                                  -----------
 
  Schein Pharmaceutical, Inc., a Delaware corporation ("Schein" or the
"Company"), hereby offers, upon the terms and subject to the conditions set
forth in this Prospectus and the accompanying letter of transmittal (the
"Letter of Transmittal," and together with this Prospectus, the "Exchange
Offer"), to exchange $1,000 principal amount of Senior Floating Rate Notes due
2004 of the Company (the "New Notes"), which have been registered under the
Securities Act of 1933, as amended (the "Securities Act"), pursuant to an
Exchange Offer Registration Statement (as defined herein) of which this
Prospectus constitutes a part, for each $1,000 principal amount of the
outstanding Senior Floating Rate Notes due 2004 of the Company (the "Old
Notes"), of which $100,000,000 aggregate principal amount is outstanding. The
form and terms of the New Notes are in all material respects the same as the
form and terms of the Old Notes, except that the New Notes will not bear
legends restricting their transfer. The New Notes will evidence the same debt
as the Old Notes (which they replace) and will be issued under and be entitled
to the benefits of the Indenture, dated as of December 24, 1997 (the
"Indenture"), among the Company, the Guarantors (as defined herein) and the
Bank of New York, as trustee (the "Trustee"). The Old Notes and the New Notes
are sometimes referred to herein collectively as the "Notes." See "The Exchange
Offer" and "Description of Notes."
 
  The indebtedness evidenced by the New Notes will be senior unsecured
obligations of the Company, will rank pari passu in right of payment with all
existing and future senior indebtedness of the Company and will rank senior in
right of payment to all existing and future indebtedness of the Company that
is, by its terms, expressly subordinated to the New Notes. Holders of secured
indebtedness of the Company, including the lenders under the Senior Credit
Agreement (as defined herein), will have claims with respect to the assets
constituting collateral for such indebtedness that are prior to the claims of
holders of the New Notes. In the event of a default on the New Notes, or a
bankruptcy, liquidation or reorganization of the Company, such assets will be
available to satisfy obligations with respect to the indebtedness secured
thereby before any payment therefrom could be made on the New Notes. To the
extent that the value of such collateral is not sufficient to satisfy the
indebtedness secured thereby, amounts remaining outstanding on such
indebtedness would be entitled to share with the Notes and their claims with
respect to any other assets of the Company. As of September 27, 1997, as
adjusted for the Initial Offering (as defined herein), the Company and its
Restricted Subsidiaries (as defined herein) would have had secured indebtedness
of approximately $160.6 million outstanding. The obligations of the Company and
the Guarantors under the Senior Credit Agreement are secured by substantially
all of the assets of the Company and the Guarantors. As of September 27, 1997,
as adjusted for the Initial Offering, the Company would have had approximately
$69.8 million of undrawn availability under the Senior Credit Agreement. The
Indenture will permit the Company and the Restricted Subsidiaries to incur
additional Indebtedness (as defined herein), including Secured Indebtedness (as
defined herein), subject to certain limitations. See "Description of Notes."
 
  All of the Company's existing and future Restricted Subsidiaries will
unconditionally guarantee on a senior unsecured basis the performance and
punctual payment when due, whether at maturity, by acceleration or otherwise,
of all obligations of the Company under the Indenture and the Notes (the
"Subsidiary Guarantees"). Each of the Guarantors has guaranteed the Company's
indebtedness under the Senior Credit Agreement on a senior secured basis. The
Subsidiary Guarantees will rank pari passu in right of payment with all
existing and future unsecured senior indebtedness of the Guarantors and senior
in right of payment to all future subordinated indebtedness of the Guarantors.
The Subsidiary Guarantee of each Guarantor will be effectively subordinated to
the prior payment in full of all secured indebtedness of such Guarantors,
including secured indebtedness under the Senior Credit Agreement. See
"Description of Notes--Guarantees."

THESE SECURITIES  HAVE NOT BEEN APPROVED  OR DISAPPROVED BY THE  SECURITIES AND

                The date of this Prospectus is February  , 1998.

(Continued from Cover Page)
 
  Interest on each New Note will accrue from the last Interest Payment Date
(as defined herein) on which interest was paid on the Old Note tendered in
exchange therefor. Holders of Old Notes whose Old Notes are accepted for
exchange will be deemed to have waived the right to receive any payment in
respect of interest on the Old Notes accrued from the last Interest Payment
Date to the date of the issuance of the New Notes. Interest on the New Notes
is payable quarterly on January 15, April 15, July 15 and October 15 of each
year, accruing from the last Interest Payment Date at a rate equal to the
Applicable LIBOR Rate (as defined herein). The Notes will be redeemable, in
whole or in part, at the option of the Company, at any time, at the redemption
prices set forth herein, plus accrued and unpaid interest thereon, to the date
of redemption. See "Description of Notes--Optional Redemption." The Notes will
mature on December 15, 2004, unless previously redeemed. The Notes will be
redeemable in cash at the option of the Company, in whole or in part, at any
time, at the redemption prices set forth herein, together with accrued
interest thereon to the date of redemption. Upon a Change of Control (as
defined herein), the Company will be required to offer to repurchase the Notes
at a purchase price equal to 101% of the principal amount thereof, plus
accrued and unpaid interest thereon to the date of repurchase.
 
  The Company will accept for exchange any and all Old Notes validly tendered
and not withdrawn prior to 5:00 p.m., New York City time on      , 1998,
unless extended by the Company in its sole discretion (the "Expiration Date").
Tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m. on the
Expiration Date. The Exchange Offer is subject to certain customary
conditions. See "The Exchange Office--Conditions."
 
  The Old Notes were sold in an aggregate principal amount of $100.0 million
by the Company on December 24, 1997 to Societe Generale Securities Corporation
(the "Initial Purchaser") in a transaction not registered under the Securities
Act in reliance upon the private offering exemption under Section 4(2) of the
Securities Act (the "Initial Offering"). The Initial Purchaser subsequently
placed the Old Notes with qualified institutional buyers in reliance upon Rule
144 A under the Securities Act and with a limited number of accredited
investors (as defined in Rule 501(A)(1), (2), (3) or (7) under the Securities
Act). Accordingly, the Old Notes may not be reoffered, resold or otherwise
transferred in the United States unless registered under the Securities Act or
unless an applicable exemption from the registration requirements of the
Securities Act is available. The New Notes are being offered hereunder in
order to satisfy the obligations of the Company and the Guarantors under the
Registration Rights Agreement (as defined herein) entered into by the Company
and the Initial Purchaser in connection with the Initial Offering. See "The
Exchange Offer."
 
  Based on no-action letters issued by the staff of the Securities and
Exchange Commission (the "Commission") to third parties, the Company believes
the New Notes issued pursuant to the Exchange Offer may be offered for resale,
resold and otherwise transferred by any holder thereof (other than any such
holder that is an "affiliate" of the Company within the meaning of Rule 405
under the Securities Act) without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such New
Notes are acquired in the ordinary course of such holder's business and such
holder has no arrangement or understanding with any person to participate in
the distribution of such New Notes. See "The Exchange Offer--Resale of the New
Notes." Each broker-dealer (a "Participating Broker-Dealer") that receives New
Notes for its own account pursuant to the Exchange Offer must acknowledge that
it will deliver a prospectus in connection with any resale of such New Notes.
The Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a Participating Broker-Dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act. This Prospectus,
as it may be amended or supplemented from time to time, may be used by a
Participating Broker-Dealer in connection with resales of New Notes received
in exchange for Old Notes where such Old Notes were acquired by such
Participating Broker-Dealer as a result of marketmaking activities or other
trading activities. The Company has agreed that, for a period of 90 days after
the Expiration Date, it will make this Prospectus available to any
participating Broker-Dealer for use in connection with any such resale. See
"Plan of Distribution."
 
  Holders of Old Notes not tendered and accepted in the Exchange Offer will
continue to hold such Old Notes and will be entitled to all the rights and
benefits and will be subject to the limitations applicable thereto under the
Indenture and with respect to transfer under the Securities Act. The Company
will pay all the expenses incurred by it incident to the Exchange Offer. See
"The Exchange Offer."
 
  There has not previously been any public market for the Old Notes or the New
Notes. There can be no assurance that an active market for the New Notes will
develop. See "Risk Factors--Lack of Public Market; Restrictions on
Transferability." Moreover, to the extent that Old Notes are tendered and
accepted in the Exchange Offer, the trading market for untendered and tendered
but unaccepted Old Notes could be adversely affected.
 
  Except as set forth below, the New Notes will initially be issued in the
form of one or more Global Notes (as defined herein), which will be deposited
with, or on behalf of, The Depository Trust Company ("DTC" or the
"Depository") and registered in its name or in the name of Cede & Co., it
nominee. Beneficial interests in the Global Notes representing the New Notes
will be shown on, and transfers thereof will be effected through, records
maintained by DTC and its participants. New Notes that are issued in respect
of Old Notes that were originally issued to Institutional Accredited Investors
(as defined herein) will be issued as Certificated Securities (as defined
herein). See "Description of Notes--Book Entry, Delivery and Form."

Company and the Guarantors other than the fiscal year in which the Exchange
Offer Registration Statement is declared effected. The Company has agreed
that, whether or not it is required to do by the rules and regulations of the

the Commission will not accept such a filing) (i) all quarterly and annual

statement so modified or superseded shall not be deemed, except as so modified

                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by, and should be read in
conjunction with, the more detailed information and financial statements and
notes thereto appearing elsewhere in this Prospectus, including information
under "Risk Factors". All references to the Company's operations for a
particular fiscal year refer to the 52-53 week period ended on the last
Saturday in December of that year, and all references to the Company's
operations for a particular fiscal quarter refer to the three month period
ended on the last Saturday in that quarter. Unless otherwise indicated, all
references to "Schein Pharmaceutical," "Schein" or the "Company" refer
collectively to Schein Pharmaceutical, Inc. and its predecessors and
subsidiaries.
 
                                  THE COMPANY
 
  Schein Pharmaceutical is one of the leading generic pharmaceutical companies
in the United States. The Company develops, manufactures and markets one of the
broadest generic product lines in the pharmaceutical industry through the
integration of its product development expertise, diverse, high-volume
production capacity and direct sales and marketing force. The Schein product
line includes both solid dosage and sterile dosage generic products, and the
Company is also developing a line of specialty branded pharmaceuticals. The
Company's primary branded product, INFeD, is the leading injectable iron
product in the United States. The Company has a substantial pipeline of
products under development, including 24 Abbreviated New Drug Applications
("ANDAs") filed with the United States Food and Drug Administration ( "FDA").
The Company supplements its internal product development, manufacturing and
marketing capabilities through strategic collaborations. Schein generated net
revenues of $478.0 million and EBITDA of $61.1 million during the 12 months
ended September 1997.
 
  The Company believes it manufactures and markets the broadest generic product
line of any U.S. pharmaceutical company in terms of number and types of
products. The Company manufactures and markets approximately 160 chemical
entities formulated in approximately 325 different dosages under approximately
200 ANDAs approved by FDA. Schein is currently the sole manufacturing source
for 47 generic pharmaceutical products, of which 45 are sterile dosage
products. The Company's solid dosage products include both immediate-release
and extended-release capsules and tablets; sterile dosage products include
solutions, suspensions, powders and lyophilized (freeze-dried) products
primarily for administration as injections, ophthalmics and otics. The
manufacture of sterile dosage products is significantly more complex than the
manufacture of solid dosage products, which limits competition in this product
area. The Company currently manufactures approximately four billion solid
dosage tablets and capsules and 75 million sterile dosage vials and ampules
annually. Solid dosage generic products and sterile dosage generic products
each accounted for approximately 40% of the Company's net revenues in the 12
months ended September 1997.
 
  Since introducing INFeD in 1992, the Company has been developing a portfolio
of branded products, primarily in select therapeutic markets, such as iron
management for the nephrology, oncology and hematology markets. INFeD is used
in the treatment of certain types of anemia, particularly in dialysis patients,
and accounted for approximately 20% of the Company's net revenues in the nine
months ended September 1997. The Company markets INFeD through a 20-person
dedicated sales and marketing force, as well as through co-marketing
collaborations with Bayer Corporation in the nephrology market and MGI Pharma,
Inc. ("MGI") in the oncology market.
 
  The Company believes its 130-person direct sales and marketing force is one
of the largest in the U.S. generic pharmaceutical industry. Through its
customized marketing programs, the Company markets its products to
approximately 60,000 customers representing all major customer channels,
including pharmaceutical wholesalers, chain and independent drug retailers,
hospitals, managed care organizations, other group purchasing organizations and
physicians.
 
  Schein's objective is to become the leading generic pharmaceutical company in
the approximately $7.4 billion generic prescription pharmaceutical industry in
the United States. The Company's growth strategy is to:
 
                                       1
<PAGE>
 
(i) leverage its diverse pharmaceutical development and manufacturing
capabilities to extend the breadth of its generic product line; (ii) focus its
product development on complex and other generic drugs that require specialized
development or manufacturing technology and are therefore expected to encounter
limited competition; (iii) develop and market branded drugs for select
therapeutic categories; (iv) pursue strategic collaborations to supplement its
product development and manufacturing resources; and (v) expand market
penetration through direct sales and innovative marketing programs.
 
  The Company's commitment to product development has resulted in 23 ANDA
approvals during the past three years and its current pipeline of 24 pending
ANDAs and over 60 additional products under development. During the past three
fiscal years, the Company, directly and through its strategic collaborations,
has expended approximately $74.0 million on product pipeline development
activities, which the Company believes is among the highest product development
expenditure levels for any independent generic drug company. The Company
pursues product development through its 150-person product development staff
and various collaborations and licensing arrangements with other pharmaceutical
and drug delivery technology companies. The Company's product development
efforts focus on: (i) major branded drugs coming off patent; (ii) drugs for
which patent protection has lapsed and for which there are few or no generic
producers; (iii) drugs whose patents may be susceptible to challenge; (iv)
proprietary and branded products focused in select therapeutic areas; and (v)
generic products that require specialized development, formulation, drug
delivery or manufacturing technology.
 
  The Company supplements its internal product development, manufacturing and
marketing capabilities with external sources. During 1994, Schein entered into
a strategic alliance with Bayer Corporation, through which Bayer Corporation
became a 28.3% stockholder of Schein, and Bayer Corporation currently
participates with Schein in several collaborations. In 1995, the Company
acquired Marsam Pharmaceuticals Inc. ("Marsam"), expanding the Company's
ability to develop and manufacture sterile penicillins and oral and sterile
cephalosporins. In addition, the Company has entered into strategic
collaborations involving product development arrangements with companies such
as Ethical Holdings plc ("Ethical") and Elan Corporation plc ("Elan"); raw
material supply arrangements with companies such as Johnson Matthey plc
("Johnson Matthey") and Abbott Laboratories ("Abbott"); and sales and marketing
arrangements with Bayer Corporation and other companies such as Elensys Care
Services, Inc. ("Elensys") and MGI.

registered trademark of A. Nattermann & Cie. GmbH. S.M.A.R.T.(TM) and

REGISTRATION RIGHTS AGREEMENT
 
  Pursuant to the Purchase Agreement, the Company and the Initial Purchaser
entered into an Exchange and Registration Rights Agreement dated as of December
24, 1997 (the "Registration Rights Agreement"), which grants the holders of the
Old Notes certain exchange and registration rights. The Exchange Offer is
intended to satisfy such exchange rights which terminate upon the consummation
of the Exchange Offer.

SECURITIES OFFERED..........  $100,000,000 aggregate principal amount of Senior

                              issued in exchange for each $1,000 principal
                              amount of Old Notes validly tendered pursuant to
                              the Exchange Offer. As of the date hereof,
                              $100,000,000 in aggregate principal amount of Old
                              Notes are outstanding. The Company will issue the

                              Based on an interpretation by the staff of the
                              Commission set forth in no-action letters issued
                              to third parties, the Company believes that New
                              Notes issued pursuant to the Exchange Offer in
                              exchange for Old Notes may be offered for resale,
                              resold and otherwise transferred by any holder
                              thereof (other than any such holder which is an
                              "affiliate" of the Company within the meaning of
                              Rule 405 under the Securities Act) without
                              compliance with the registration and prospectus
                              delivery provisions of the Securities Act,
                              provided that such New Notes are acquired in the
                              ordinary course of such holder's business and
                              that such holder does not intend to participate
                              and has no arrangement or understanding with any
                              person to participate in the distribution of such
                              New Notes. Each holder accepting the Exchange
                              Offer is required to represent to the Company in
                              the Letter of Transmittal that, among other
                              things, the New Notes will be acquired by the
                              holder in the ordinary course of business and the
                              holder does not intend to participate and has no
                              arrangement or understanding with any person to
                              participate in the distribution of such New
                              Notes.
 
                              Any Participating Broker-Dealer that acquired Old
                              Notes for its own account as a result of market-

                              resale of such New Notes. The Letter of
                              Transmittal states that by so acknowledging and
                              by delivering a prospectus, a Participating
                              Broker-Dealer will not be deemed to admit that it
                              is an "underwriter" within the meaning of the
                              Securities Act. This Prospectus, as it may be

                              acquired by such Participating Broker-Dealer as a
                              result of market-making activities or other
                              trading activities. The Company has agreed that,
                              for a period of 90 days after the Expiration
                              Date, it will make this Prospectus available to

                              may result in such holder incurring liability

                              appropriate form under the Securities Act
                              relating to the offer and sale of the Notes by
                              the holders thereof, from time to time, in
                              accordance with such registration statement and
                              Rule 415 under the Securities Act (the "Shelf
                              Registration Statement"). The Company will use
                              commercially reasonable efforts to have the
                              Exchange Offer Registration Statement or, if
                              applicable, a Shelf Registration Statement (each
                              a "Registration Statement") declared effective by
                              the Commission as promptly as practicable after
                              the filing thereof. Unless the Exchange Offer
                              would not be permitted by a policy of the
                              Commission, the Company will commence the
                              Exchange Offer and will use its reasonable best
                              efforts to consummate the Exchange Offer as
                              promptly as practicable, but in any event on or
                              prior to 150

                              days after the Issue Date. If applicable, the
                              Company will use commercially reasonable best
                              efforts to keep the Shelf Registration Statement
                              effective for the earlier of three years from the
                              Issue Date or such shorter period that will
                              terminate when all the Notes covered by the Shelf
                              Registration Statement have been sold, subject to
                              certain exceptions, including suspending the
                              effectiveness thereof as required by law or for
                              certain valid business reasons.
 
SPECIAL PROCEDURES FOR
 BENEFICIAL OWNERS..........  Any beneficial owner whose Old Notes are
                              registered in the name of a broker, dealer,
                              commercial bank, trust company or other nominee
                              and who wishes to tender should contact such
                              registered holder promptly and instruct such
                              registered holder to tender on such beneficial
                              owner's behalf. If such beneficial owner wishes
                              to tender on such owner's own behalf, such owner
                              must, prior to completing and executing the
                              Letter of Transmittal and delivering its Old
                              Notes, either make appropriate arrangements to
                              register ownership of the Old Notes in such
                              owner's name or obtain a properly completed bond
                              power from the registered holder. The transfer of
                              registered ownership may take considerable time.
                              The Company will keep the Exchange Offer open for
                              not less than twenty business days in order to
                              provide for the transfer of registered ownership.

                                 THE NEW NOTES
 
GENERAL.....................  The form and terms of the New Notes are the same
                              as the form and terms of the Old Notes (which
                              they replace) except that the New Notes have been
                              registered under the Securities Act and,
                              therefore, will not bear legends restricting the
                              transfer thereof, and (ii) the holders of New
                              Notes will not be entitled to certain rights
                              under the Registration Rights Agreement,
                              including the provisions providing for an
                              increase in the interest rate on the Old Notes in
                              certain circumstances relating to the timing of
                              the Exchange Offer, which rights will terminate
                              when the Exchange Offer is consummated. See "The
                              Exchange Offer--Purpose and Effect of the
                              Exchange Offer." The New Notes will evidence the
                              same debt as the Old Notes and will be entitled
                              to the benefits of the Indenture. See
                              "Description of Notes." The Old Notes and the New
                              Notes are referred to collectively hereinafter as

SUBSIDIARY GUARANTEES.......  All of the Company's existing and future
                              Restricted Subsidiaries will unconditionally

                              performance and punctual payment when due,
                              whether at maturity, by acceleration or
                              otherwise, of all obligations of the Company
                              under the Indenture and the Notes. The Subsidiary

                              rank pari passu with all existing and future
                              senior indebtedness of the Company and will rank
                              senior

                              in right of payment to all existing and future
                              indebtedness of the Company that is, by its
                              terms, expressly subordinated to the Notes.
                              Holders of secured indebtedness of the Company,
                              including the lenders under the Senior Credit
                              Agreement, will have claims with respect to the
                              assets constituting collateral for such
                              indebtedness that are prior to the claims of
                              holders of the Notes. In the event of a default
                              on the Notes, or a bankruptcy, liquidation or
                              reorganization of the Company, such assets will
                              be available to satisfy obligations with respect
                              to the indebtedness secured thereby before any
                              payment therefrom could be made on the Notes. To
                              the extent that such collateral is not sufficient
                              to satisfy the indebtedness secured thereby,
                              amounts remaining outstanding on such
                              indebtedness would be entitled to share with the
                              Notes and their claims with respect to any other
                              assets of the Company. As of September 27, 1997,
                              as adjusted for the Initial Offering, the Company
                              and its Restricted Subsidiaries would have had
                              secured indebtedness of approximately $160.6
                              million outstanding. The obligations of the
                              Company and the Guarantors under the Senior
                              Credit Agreement are secured by substantially all
                              of the assets of the Company and the Guarantors.
                              As of September 27, 1997, as adjusted for the
                              Offering, the Company would have had
                              approximately $69.8 million of undrawn
                              availability under the Senior Credit Agreement.
                              The Indenture relating to the Notes will permit
                              the Company and the Restricted Subsidiaries to
                              incur additional Indebtedness, including Secured
                              Indebtedness, subject to certain limitations. See
                              "Description of Notes."
 
CHANGE OF CONTROL...........  Upon a Change of Control, each holder of Notes
                              may require the Company to repurchase any or all
                              outstanding Notes owned by such holder at 101% of
                              the principal amount thereof, plus accrued and
                              unpaid interest thereon, to the date of
                              repurchase. See "Description of Notes--Change of
                              Control."
 
RESTRICTIVE COVENANTS.......  The Indenture under which the New Notes will be
                              issued contains certain covenants pertaining to
                              the Company and its Restricted Subsidiaries,
                              including but not limited to covenants with
                              respect to the following matters: (i) limitations
                              on indebtedness; (ii) limitations on restricted
                              payments such as dividends, repurchases of the
                              Company's or subsidiaries' stock, repurchases of
                              subordinated obligations and investments; (iii)
                              limitations on liens; (iv) limitations on
                              engaging in certain lines of business; (v)
                              limitations on mergers, consolidations and
                              transfers of all or substantially all assets;
                              (vi) limitations on restrictions on distributions
                              from restricted subsidiaries; (vii) limitations
                              on sales of assets and of stock of subsidiaries;
                              (viii) limitations on transactions with
                              affiliates; (ix) limitations on the sale of
                              capital stock of restricted subsidiaries; and (x)
                              limitations on sale and leaseback transactions.
                              However, all of these covenants are subject to a
                              number of important qualifications and
                              exceptions. See "Description of Notes--Certain
                              Covenants."

                              and (ii) to use commercially reasonable efforts
                              to cause the Exchange Offer Registration
                              Statement to be declared effective under the
                              Securities Act within the earlier of (A) 90 days
                              after the Issue Date or (B) 30 days after the
                              consummation of the initial public offering of
                              the Company's Common Stock. Upon the
                              effectiveness of the Exchange Offer Registration
                              Statement, the Company will commence the Exchange
                              Offer to holders of the Notes who are not
                              prohibited by any law or policy of the Commission
                              from participating in the Exchange Offer. The
                              Company will keep the Exchange Offer open for not
                              less than 30 days (or longer, if required by
                              applicable law) after the date notice of the
                              Exchange Offer is mailed to the holders of the
                              Old Notes. If (i) any change in law or applicable
                              interpretations of the staff of the Commission
                              does not permit the Company to effect the
                              Exchange Offer as contemplated thereby or (ii)
                              the Initial Purchaser, as a holder of Notes, (A)
                              is not eligible to participate in the Exchange
                              Offer or (B) participates in the Exchange Offer
                              and does not receive freely transferable Exchange
                              Notes in exchange for tendered Old Notes, the
                              Company will file with the Commission and use
                              commercially reasonable efforts to cause to be
                              declared effective on or prior to the latter of
                              (x) 120 days after the Issue Date or (y) 45 days
                              after the publication of the change in law or
                              interpretation, the Shelf Registration Statement.
 
                              The Company will use commercially reasonable
                              efforts to have the Exchange Offer Registration
                              Statement or, if applicable, a Shelf Registration
                              Statement (each a "Registration Statement")
                              declared effective by the Commission as promptly
                              as practicable after the filing thereof. Unless
                              the Exchange Offer would not be permitted by a
                              policy of the Commission, the Company will
                              commence the Exchange Offer and will use its
                              reasonable best efforts to consummate the
                              Exchange Offer as promptly as practicable, but in
                              any event on or prior to 150 days after the Issue
                              Date. If applicable, the Company will use
                              commercially reasonable best efforts to keep the
                              Shelf Registration Statement effective for the
                              earlier of three years from the Issue Date or
                              such shorter period that will terminate when all
                              the Notes covered by the Shelf Registration
                              Statement have been sold, subject to certain
                              exceptions, including suspending the
                              effectiveness thereof as required by law or for
                              certain valid business reasons.
 
TRANSFER RESTRICTIONS;
 ABSENCE OF A PUBLIC MARKET   The Old Notes have not been registered under the
 FOR THE NOTES..............  Securities Act and are subject to restrictions on
                              transferability and resale. If issued, the New
                              Notes will generally be freely transferable
                              (subject to the

                              restrictions discussed elsewhere herein) but will
                              be new securities for which there will not
                              initially be a market. Accordingly, there can be
                              no assurance as to the development or liquidity
                              of any market for the Old Notes or, if issued,
                              the New Notes. The Notes have been designated
                              eligible for trading in the PORTAL market. The
                              Initial Purchaser has advised the Company that it
                              currently intends to make a market in the Notes.
                              However, the Initial Purchaser is not obligated
                              to do so, and any market making with respect to
                              the Notes may be discontinued at any time without
                              notice. The Company does not intend to apply for
                              a listing of the Old Notes, or, if issued, the
                              New Notes, on any securities exchange or on any
                              automated dealer quotation system.

- --------
(1) Includes the results of Marsam from September 1995, the date of purchase.
    In connection with the purchase of Marsam, the Company recognized acquired
    in-process research and development. See "Management's Discussion and
    Analysis of Financial Condition and Results of Operations" and Note 3 to
    the Consolidated Financial Statements of the Company.
(2) Special compensation, restructuring and relocation expenses includes costs
    recognized by the Company in connection with its restructuring and
    relocation of its corporate headquarters. See "Management's Discussion and
    Analysis of Financial Condition and Results of Operations" and Notes 2 and
    13 to the Consolidated Financial Statements of the Company.
(3) Other expense (income), net, includes equity in earnings (loss) of
    unconsolidated international ventures of $(0.4) million and $(3.4) million
    in fiscal 1995 and 1996, respectively and $(1.6) million and $(2.7) million
    in the nine months ended September 1996 and 1997, respectively, gain on
    sales of marketable securities of $9.9 million in the nine months ended
    September 1997, a settlement contingency of $8.0 million in fiscal 1993,
    and $0.5 million of an extraordinary item in fiscal 1992.
(4) EBITDA is defined as income (loss) before provision for income taxes and
    minority interest, interest expense and depreciation and amortization
    including the $30 million charge in fiscal 1995 of acquired in-process
    Marsam research and development. The Company has included information
    concerning EBITDA in this Registration Statement because it believes that
    such information may be used by certain investors as one measure of a
    company's historical ability to service debt. EBITDA should not be
    considered as an alternative to, or more meaningful than, earnings from
    operations or other traditional indications of a company's operating
    performance.
(5) The ratio of earnings to fixed charges is computed by dividing (i) income
    (loss) before provision for income taxes and minority interest plus fixed
    charges by (ii) fixed charges. Fixed charges consist of interest on
    indebtedness including amortization of debt issuance costs and the
    estimated interest component of rental expense (assumed to be one-third).
    In fiscal 1995, fixed charges exceeded income (loss) before provision for
    income taxes and minority interest by $4.4 million.
(6) Pro forma cash interest expense is defined as historical interest expense,
    adjusted for (i) the exclusion of amortization of deferred financing fees
    of $2.2 million in fiscal 1996 and $2.3 million in the nine months ended
    September 1997, respectively, (ii) interest expense as if the Initial
    Offering had occurred on December 31, 1995 and the proceeds were used to
    repay the Senior Subordinated Loan or its predecessor debt and (iii)
    interest expense associated with drawdowns under the revolving credit
    facility under the Senior Credit Agreement which were used to pay the $4.2
    million in fees and expenses incurred as a result of the Initial Offering.
(7) As adjusted to give effect to the Initial Offering and the payment of $4.2
    million in fees and expenses in connection therewith, using proceeds from
    the Company's revolving credit facility under the Senior Credit Agreement.

                                 RISK FACTORS
 
  Prospective investors in the New Notes should carefully consider the
following risk factors, in addition to the other information set forth in this
Prospectus, before making an investment in the New Notes offered hereby. This
Prospectus contains statements which constitute forward-looking statements
within the meaning of the Private Securities Litigation Reform Act of 1995.
Those statements appear in a number of places herein and include statements
regarding the intent, belief or current expectations of the Company, primarily
with respect to the future operating performance of the Company or related
industry developments. Prospective purchasers of the New Notes are cautioned
that any such forward-looking statements are not guarantees of future
performance and involve risks and uncertainties, and that actual results and
industry developments may differ from those described in the forward-looking
statements as a result of various factors, many of which are beyond the
control of the Company. The information contained herein, including, without
limitation, the information set forth below and the information under the
heading "Management's Discussion and Analysis of Financial Condition and
Results of Operations," identifies important factors that could cause such
differences.
 
RISK FACTORS RELATED TO THE NOTES
 
 Consequences of Failure to Exchange
 
  Untendered Old Notes not exchanged for New Notes pursuant to the Exchange
Offer will remain subject to the existing restrictions upon transfer of such
Old Notes. Additionally, holders of any Old Notes not tendered in the Exchange
Offer prior to the Expiration Date will not be entitled to require the Company
to file the Shelf Registration Statement.
 
 Substantial Leverage
 
  The Company is highly leveraged. As of September 27, 1997, as adjusted for
the Initial Offering, the Company would have had total consolidated
indebtedness of $260.6 million. In addition, subject to certain restrictions
set forth in the Senior Credit Agreement and the Indenture, the Company may
incur additional indebtedness in the future for acquisitions, capital
expenditures and other corporate purposes.
 
  The Company's high degree of leverage could have important consequences,
including the following: (i) the Company's ability to obtain additional
financing in the future for working capital, capital expenditures,
acquisitions, general corporate purposes or other purposes may be impaired;
(ii) a substantial portion of the Company's cash flow from operations must be
dedicated to the payment of principal and interest on the Notes and its other
indebtedness, thereby reducing the funds available to the Company for other
purposes; (iii) the financial covenants and other restrictions contained in
the Senior Credit Agreement and the Indenture and other agreements relating to
the Company's indebtedness require the Company to meet certain financial
tests, restrict its ability to borrow additional funds and impose limitations
on the disposition of assets; (iv) obligations in respect of the Senior Credit
Agreement are, and the Notes will be, and other indebtedness of the Company
may be, at variable rates of interest, which expose the Company to the risk of
increased interest rates; (v) all of the indebtedness outstanding under the
Senior Credit Agreement is secured by substantially all the assets of the
Company and matures prior to the maturity of the Notes; (vi) the Company may
be substantially more leveraged than certain of its competitors, which may
place the Company at a competitive disadvantage; and (vii) the Company's
substantial degree of leverage may limit its flexibility to adjust to changing
market conditions and make it more vulnerable to a downturn in general
economic conditions or its business. See "Description of Notes."
 
  The Company's ability to make scheduled payments of the principal of, or
interest on, or to refinance its indebtedness (including the Notes) depends on
its future operating performance, which to a certain extent is subject to
economic, financial, competitive and other factors beyond its control. The
Company believes that, based on its current level of operations and
anticipated growth, its cash flow from operations will be adequate to meet its
anticipated requirements for working capital, capital expenditures, interest
payments and scheduled principal payments over the next several years. There
can be no assurance, however, that the Company's business
 
                                      12
<PAGE>
 
will generate cash flow at or above expected levels. If the Company is unable
to generate sufficient cash flow from operations in the future to service its
debt, fund working capital requirements and make necessary capital
expenditures, or its future earnings are insufficient to make all required
principal payments out of internally generated funds, the Company may be
required to refinance all or a portion of its existing debt, sell assets or
obtain additional financing. There can be no assurance that any such
refinancing or asset sales would be possible or that any additional financing
could be obtained on terms acceptable to the Company or at all, particularly
in view of the Company's high level of debt. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources."
 
 Ability to Service Debt
 
  The Company's ability to make scheduled payments or to refinance its
obligations with respect to its indebtedness will depend on its financial and
operating performance, which in turn will be subject to prevailing economic
conditions and to certain financial, business and other factors beyond its
control. If the Company's cash flow and capital resources are insufficient to
fund its debt service obligations, the Company may be forced to reduce or
delay planned expansion and capital expenditures, sell assets, obtain
additional equity capital or restructure its debt. There can be no assurance
that the Company's operating results, cash flow and capital resources will be
sufficient for payment of its indebtedness in the future. In the absence of
such operating results and resources, the Company could face substantial
liquidity problems and might be required to dispose of material assets or
operations to meet its debt service and other obligations, and there can be no
assurance as to the timing of such sales or the proceeds that the Company
could realize therefrom. In addition, because the Notes will bear interest at
floating rates and the Senior Credit Agreement bears interest at floating
rates, an increase in interest rates could adversely affect, among other
things, the Company's ability to meet its debt service obligations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources" and "Description of Notes."
 
 Ranking of Notes
 
  The New Notes will be senior unsecured obligations of the Company and will
rank pari passu in right of payment with all current and future unsecured
senior indebtedness of the Company. The New Notes will (i) rank senior in
right of payment to all subordinated indebtedness of the Company and (ii) be
guaranteed, on a senior unsecured basis, by the Restricted Subsidiaries of the
Company. The New Notes will also be effectively subordinated to all existing
and future indebtedness of any subsidiary of the Company that is not a
Guarantor of the Notes.
 
  The indebtedness incurred under the Senior Credit Agreement is secured by
substantially all of the assets of the Company. In addition, the Indenture
will permit the Company and the Guarantors to incur certain other secured
indebtedness. The holders of all existing and future secured indebtedness will
have a claim prior to the holders of the Notes with respect to any assets
pledged by the Company and the Guarantors as security for such indebtedness.
Further, as of September 27, 1997, as adjusted for the Initial Offering, the
Senior Credit Agreement would have provided the Company with $69.8 million of
undrawn availability, which, if drawn, would effectively rank prior to the
Notes and the Subsidiary Guarantees. Upon an event of default under the Senior
Credit Agreement, the lenders thereunder would be entitled to foreclose on the
assets of the Company and the Guarantors pledged as security for the
indebtedness incurred thereunder. In such event, the assets of the Company and
the Guarantors remaining after payment of such secured indebtedness may be
insufficient to satisfy the obligations of the Company and the Guarantors with
respect to the Notes and the Subsidiary Guarantees. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources" and "Description of Notes."
 
  As of September 27, 1997, as adjusted for the Initial Offering, the
aggregate principal amount of secured indebtedness of the Company and the
Guarantors which would have effectively ranked senior to the Notes and the
Subsidiary Guarantees would have been approximately $160.6 million.

 Fraudulent Conveyance
 
  The issuance of the Notes and the Subsidiary Guarantees may be subject to
review by a court under federal bankruptcy law or comparable provisions of
state fraudulent transfer law. Under federal or state fraudulent transfer
laws, if a court were to find that, at the time the Notes and Subsidiary
Guarantees were issued, the Company or a Guarantor, as the case may be, (i)
issued the Notes or a Subsidiary Guarantee with the intent of hindering,
delaying or defrauding current or future creditors or (ii)(A) received less
than fair consideration or reasonably equivalent value for incurring the
indebtedness represented by the Notes or a Subsidiary Guarantee and (B)(1) was
insolvent or was rendered insolvent by reason of the issuance of the Notes or
such Subsidiary Guarantee, (2) was engaged, or about to engage, in a business
or transaction for which its remaining assets constituted unreasonably small
capital or (3) intended to incur, or believed (or should have believed) it
would incur, debts beyond its ability to pay as such debts mature (as all of
the foregoing terms are defined in or interpreted under such fraudulent
transfer statutes), such court could avoid all or a portion of the Company's
or a Guarantor's obligations to the holders of the Notes or subordinate the
Company's or a Guarantor's obligations to the holders of the Notes to other
existing and future indebtedness of the Company or such Guarantor, as the case
may be, the effect of which would be to entitle such other creditors to be
paid in full before any payment could be made on the Notes, and take other
action detrimental to the holders of the Notes, including in certain
circumstances, invalidating the Notes. In that event, there would be no
assurance that any repayment on the Notes would ever be recovered by the
holders of the Notes.
 
  The definition of insolvency for purposes of the foregoing considerations
varies among jurisdictions depending upon the federal or state law that is
being applied in any such proceeding. However, the Company or a Guarantor
generally would be considered insolvent at the time it incurs the indebtedness
constituting the Notes or a Subsidiary Guarantee, as the case may be, if (i)
the fair market value (or fair saleable value) of its assets is less than the
amount required to pay its total existing debts and liabilities (including the
probable liability on contingent liabilities) as they become absolute or
matured or (ii) it is incurring debts beyond its ability to pay as such debts
mature.
 
  There can be no assurance as to what standard a court would apply in order
to evaluate the parties' intent or to determine whether the Company or a
Guarantor, as the case may be, was insolvent at the time, or rendered
insolvent upon consummation, of the sale of the Notes or the issuance of a
Subsidiary Guarantee or that, regardless of the method of valuation, a court
would not determine that the Company or a Guarantor, as the case may be, was
insolvent at the time, or rendered insolvent upon consummation, of the Initial
Offering. Nor can there be any assurance that a court would not determine,
regardless of whether the Company or a Guarantor was insolvent on the date the
Notes and Subsidiary Guarantees were issued, that the payments constituted
fraudulent transfers on another ground.
 
  In addition, the Subsidiary Guarantees could also be subject to the claim
that, since the Subsidiary Guarantees were incurred for the benefit of the
Company (and only indirectly for the benefit of the Guarantors), the
obligations of the Guarantors thereunder were incurred for less than
reasonably equivalent value or fair consideration. A court could avoid a
Guarantor's obligation under its Subsidiary Guarantee, subordinate the
Subsidiary Guarantee to other indebtedness of such Guarantor or take other
action detrimental to the holders of the Notes.
 
 Restrictions Imposed by Terms of the Company's Indebtedness
 
  The Indenture contains certain covenants that, among other things: (i) limit
the ability of the Company and its Restricted Subsidiaries to incur additional
indebtedness, repay other indebtedness and amend other debt instruments; (ii)
restrict the ability of the Company and its Restricted Subsidiaries to make
dividends and other restricted payments (including investments); (iii) limit
the ability of the Company and its Restricted Subsidiaries to incur certain
liens; (iv) limit the ability of the Company to engage in other lines of
business; (v) limit the ability of the Company to consolidate or merge with or
into, or to sell, assign, transfer, lease, convey or otherwise dispose of all
or substantially all of its assets to, another person; (vi) limit the ability
of the Restricted Subsidiaries to create restrictions on the payment of
dividends and other payments; (vii) limit the ability of the
 
                                      14
<PAGE>
 
Company and its Restricted Subsidiaries to make sales of assets and stock of a
subsidiary; (viii) limit transactions by the Company and its Restricted
Subsidiaries with affiliates; (ix) limit the sale of capital stock of
Restricted Subsidiaries; and (x) limit the ability of the Company and its
Restricted Subsidiaries to enter into sale and leaseback transactions. In
addition, the Senior Credit Agreement also contains certain other restrictive
covenants which are generally more restrictive than those contained in the
Indenture and limit the Company's ability to prepay its other indebtedness
(including the Notes). The Senior Credit Agreement also requires the Company
to maintain specified consolidated financial ratios and satisfy certain
consolidated financial tests. See "Description of Certain Indebtedness" and
"Description of Notes."
 
  The Company's ability to comply with the covenants in the Indenture and the
Senior Credit Agreement may be affected by events beyond its control,
including prevailing economic, financial, competitive, legislative, regulatory
and other conditions. The breach of any such covenants or restrictions could
result in a default under the Indenture and/or the Senior Credit Agreement,
which would permit the holders of the Notes and/or the lenders under the
Senior Credit Agreement, as the case may be, to declare all amounts borrowed
thereunder to be due and payable, together with accrued and unpaid interest,
and the commitments of the lenders to make further extensions of credit under
the Senior Credit Agreement could be terminated. If the Company was unable to
repay its indebtedness to the lenders under the Senior Credit Agreement, such
lenders could proceed against any or all of the collateral securing the
indebtedness under the Senior Credit Agreement, which collateral will consist
of substantially all of the assets of the Company and the Guarantors. In
addition, if the Company fails to comply with the financial and operating
covenants contained in the Senior Credit Agreement, such failure could result
in an event of default thereunder, which could permit the acceleration of the
debt incurred thereunder and, in some cases, cross-acceleration and cross-
default of indebtedness outstanding under other debt instruments of the
Company, including the Notes. See "Description of Notes."
 
 Limitation on Change in Control
 
  Upon a Change of Control, the Company will be required to offer to purchase
all of the outstanding Notes at a price equal to 101% of the principal amount
thereof plus accrued and unpaid interest thereon to the date of repurchase.
 
  The Senior Credit Agreement also provides that certain change of control
events with respect to the Company constitute a default thereunder. Any future
credit agreements or other agreements to which the Company becomes a party may
contain similar restrictions and provisions. In the event a Change of Control
occurs at a time when the Company is prohibited from purchasing the Notes, or
if the Company is required to make an asset sale offer pursuant to the terms
of the Notes, the Company could seek the consent of its lenders to purchase
the Notes or could attempt to refinance the borrowings that contain such
prohibition. If the Company does not obtain such a consent or refinance such
borrowings, the Company will remain prohibited from purchasing the Notes. In
such case, the Company's failure to purchase tendered Notes would constitute
an Event of Default as defined under the Indenture. If, as a result thereof, a
default occurs with respect to any other senior indebtedness, payments to the
holders of the Notes could be limited.
 
  In addition, the Change of Control provisions may not be waived by the Board
of Directors of the Company or the Trustee without the consent of holders of
at least a majority in principal amount of the Notes. As a result, the Change
of Control provisions of the Notes may in certain circumstances discourage or
make more difficult a sale or takeover of the Company and, thus, the removal
of incumbent management. The Equity Offering will not constitute a Change in
Control. See "Description of Notes--Change of Control."
 
 Lack of Public Market; Restrictions on Transferability
 
  Pursuant to the Registration Rights Agreement, the Company and the
Guarantors have agreed to file the Exchange Offer Registration Statement with
the Commission and to use their best efforts to cause such registration
statement to become effective with respect to the New Notes. If issued, the
New Notes generally
 
                                      15
<PAGE>
 
will be permitted to be resold or otherwise transferred by each holder without
the requirement of further registration. The New Notes, however, will also
constitute a new issue of securities with no established trading market. The
Exchange Offer will not be conditioned upon any minimum or maximum aggregate
principal amount of Old Notes being tendered for exchange. No assurance can be
given as to the liquidity of the trading market for the New Notes following
the Exchange Offer. See "The Exchange Offer."
 
  The liquidity of, and trading market for, the New Notes also may be
adversely affected by a general decline in the market for similar securities.
Such a decline may adversely affect such liquidity and trading markets
independent of the financial performance of, and prospects for, the Company.
 
RISK FACTORS RELATED TO THE COMPANY'S OPERATIONS
 
 Dependence Upon New Products and Effect of Product Lifecycles
 
  The Company's results of operations depend, to a significant extent, upon
its ability to develop and commercialize new pharmaceutical products in
response to the competitive dynamics within the pharmaceutical industry.
Generally, following the expiration of patents and any other market
exclusivity periods for branded drugs, the first pharmaceutical manufacturers
successfully to market generic equivalents of such drugs achieve higher
revenues and gross profit from the sale of such generic drugs than do others
from the sale of generic equivalents subsequently approved. As competing
generic products reach the market, the prices, sales volumes and profit
margins of the first generic versions often decline significantly. For these
reasons, the Company's ability to achieve growth in revenues and profitability
depends on its being among the first companies regularly to introduce new
generic products. While the Company believes the pipeline of generic drugs and
branded drugs it currently has under development will allow it to compete
effectively, no assurance can be given that any of the drugs in its pipeline
will be successfully developed or approved by FDA, will be among the first to
the market or will achieve significant revenues and profitability. See "--
Dependence on Successful Patent Litigation," "--Competition," "--Dependence on
Regulatory Approval and Compliance," "--Pending Regulatory Matters,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business."
 
 Dependence on Certain Existing Products
 
  The Company derives and is expected to continue to derive a significant
portion of its revenues and gross profit from a limited number of products.
Net revenues from INFeD in 1996 and the nine months ended September 1997 were
$88.0 million and $72.1 million or 19% and 20%, respectively, of the Company's
total net revenues, with gross profit from INFeD as a percentage of total
gross profit being significantly greater. Any material decline in revenues or
gross profit from these products could have a material adverse effect on the
Company's business, results of operations and financial condition. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business--Products."
 
 Dependence on Successful Patent Litigation
 
  A significant portion of the Company's revenues and gross profit has been
derived from generic versions of branded drug products covered by patents the
Company has challenged under the Drug Price Competition and Patent Term
Restoration Act of 1984 (the "Waxman-Hatch Act"). In several successful
proceedings, the Company has been advised and represented by an independent
patent attorney, Alfred B. Engelberg (the "Consultant"), whose involvement has
been substantial. The Company expects that the Consultant will be involved
with the Company in no more than two additional patent challenges, one of
which is currently being litigated. Through its internal efforts, and with the
assistance of third-party collaborators and advisors, the Company has
identified a number of additional patents that may be susceptible to
challenge. There can be no assurance the Company will successfully complete
the development of any additional products involving patent challenges,
succeed in any pending or future patent challenges or, if successful, receive
significant revenues or profit from the products covered by successfully
challenged patents. See "--Dependence Upon New Products

and Effect of Product Lifecycles," "Management's Discussion and Analysis of
Financial Condition and Results of Operations," and "Business--Government
Regulations."
 
 Competition
 
  The pharmaceutical industry is intensely competitive. The Company competes
with numerous companies in the pharmaceutical industry generally and the
generic segment of the industry specifically. These competitors include
generic drug manufacturers and large pharmaceutical companies that continue to
manufacture the branded and/or generic versions of drugs after the expiration
of their patents relating to these drugs. Many of the Company's competitors
have greater financial and other resources than the Company and, therefore,
are able to spend more than the Company on research, product development and
marketing. In addition, following the expiration of patents on branded drugs,
manufacturers of these products have employed various strategies intended to
maximize their share of the markets for these products, as well as, in some
cases, generic equivalents of these products, and are expected to continue to
do so in the future. There can be no assurance that developments by others
will not render any product the Company produces or may produce obsolete or
otherwise non-competitive. See "--Dependence Upon New Products and Effect of
Product Lifecycles," "--Consolidation of Distribution Network; Customer
Concentration" and "Business--Competition."
 
 Dependence on Regulatory Approval and Compliance
 
  The development, manufacture, marketing and sale of pharmaceutical products
is subject to extensive federal, state and local regulation in the U.S. and
similar regulation in other countries. The Company, like its competitors, must
obtain approval from FDA before marketing most drugs, and must demonstrate
continuing compliance with current Good Manufacturing Practices ("cGMP")
regulations. Generally, for generic products an ANDA is submitted to FDA, and
for new drugs, a New Drug Application ("NDA") is submitted. Under certain
circumstances following product approval and market introduction, FDA can
request product recalls, seize inventories and merchandise in commerce, move
to enjoin further manufacture and product distribution, suspend distribution
or withdraw FDA approval of the product, and debar a company from submitting
new applications. FDA also can take administrative action against a company to
suspend substantive review of pending applications and withhold approvals, if
it concludes that the data and applications from that company may not be
reliable or that there are significant unresolved cGMP issues pertinent to the
manufacture of drugs at a particular facility of that company. Any such
actions are likely to have a material adverse effect on a company's business.
The Company has ANDAs currently pending before FDA and intends to file
additional ANDAs in the future. Delays in the review of these applications or
the inability of the Company to obtain approval of certain of these
applications or to market the product following approval could have a material
adverse effect on the Company's business, results of operations and financial
condition. See "--Dependence Upon New Products and Effect of Product
Lifecycles," "--Pending Regulatory Matters" and "Business--Government
Regulations."
 
 Pending Regulatory Matters
 
  In early 1996, FDA conducted an inspection of the operations of the
Company's subsidiary, Steris Laboratories, Inc. ("Steris"), located in
Phoenix, Arizona. At the conclusion of that inspection, FDA identified various
cGMP manufacturing and reporting deficiencies in Steris' operations. Steris
was advised by FDA that it will not approve any ANDAs for products
manufactured at the Steris facility until FDA confirms that the manufacturing
and reporting deficiencies have been corrected. Ten of the Company's pending
ANDAs have been filed from the Steris facility. Following the 1996 inspection,
Steris implemented numerous measures to correct these deficiencies and place
Steris in compliance with applicable FDA manufacturing and reporting
requirements.
 
  In July 1997, FDA conducted a follow-up inspection of the Steris facility.
At the conclusion of that inspection, FDA identified additional cGMP
deficiencies at the Steris facility. Steris has implemented measures intended
to correct these deficiencies and believes that a full reinspection will be
required before FDA will approve ANDAs for new products manufactured at the
Steris facility. While the Company is currently discussing with FDA the timing
of this reinspection, no assurance can be given as to when it will take place.
Since the July
 
                                      17
<PAGE>
 
1997 inspection, Steris has provided FDA with information concerning the
completion of corrective action measures it has implemented and the status of
measures not yet completed. Recently, FDA requested that Steris provide a time
frame for completion of corrective action measures still in progress. Steris
intends to provide FDA with the information it has requested and to seek a
timely reinspection of its facilities. In early 1998, FDA issued a Warning
Letter relating to the deficiencies observed in the 1997 inspection.
 
  Following the 1996 inspection of Steris, FDA's Office of Regulatory Affairs
staff commenced an investigation of Steris' operations that focused primarily
on drug stability issues, including Steris' alleged failure to notify FDA on
an adequate and timely basis of drug stability problems with respect to
certain products manufactured at the Steris facility. On the basis of this
investigation, the U.S. Department of Justice ("DOJ") notified Steris in a
letter dated July 28, 1997 that the alleged reporting deficiencies constituted
serious breaches of regulatory obligations and indicated that it would be
willing to negotiate a settlement of the alleged violations with Steris. On
February 5, 1998 Steris entered into a plea agreement requiring Steris to pay
a fine of $1.0 million and pleading guilty to misdemeanor violations for
failure to observe application reporting requirements for two drugs during
1994 and 1995. While the Company does not expect any other sanctions to arise
in respect of this matter, any such sanctions could have a material adverse
effect on the Company's business, results of operations and financial
condition.
 
  In 1995, FDA inspected the operations of the Company's subsidiary, Danbury
Pharmacal, Inc. ("Danbury"), which operates facilities in Carmel, New York and
Danbury, Connecticut. As a result of observations made by FDA relating to
Danbury's compliance with cGMP requirements and the integrity of the data
submitted by Danbury in support of certain ANDAs, Danbury voluntarily audited
all data submitted in connection with 26 of its pending and approved ANDAs.
Since the 1995 inspection, FDA has continued to approve ANDAs for products
manufactured by Danbury. From August to October 1997, FDA reinspected
Danbury's facilities. FDA observed certain cGMP deficiencies which the Company
has corrected in a manner satisfactory to FDA. FDA is currently conducting an
additional inspection of those facilities, which involves primarily
evaluations of the ANDA audits and the procedural changes Danbury instituted
to remedy cGMP deficiencies observed during the 1995 FDA inspection. During
the course of the inspection, FDA has noted deficiencies relating to certain
testing records.
 
  In June 1997, FDA conducted an ANDA preapproval and cGMP inspection at the
Company's Marsam subsidiary, located in Cherry Hill, New Jersey. Although the
inspection focused primarily on issues relating to the manufacture of certain
drug products that are the subject of five pending ANDAs, the inspection also
included an examination of Marsam's general compliance with cGMP requirements.
Marsam was informed at the conclusion of the inspection that FDA intended to
withhold approval of the five ANDAs until certain alleged cGMP deficiencies
are corrected. Marsam has provided FDA with information it believes
demonstrates that the alleged deficiencies are not significant and that
corrective measures have been implemented. A follow-up inspection was
conducted to determine whether these corrective actions have been implemented
satisfactorily. Based upon the results of this inspection, FDA has informed
Marsam that its corrective actions are satisfactory and that FDA is prepared
to grant approvals of qualified ANDAs. Seven of the Company's pending ANDAs
have been filed from the Marsam facility.
 
  There can be no assurance that FDA will determine that the Company has
adequately corrected the alleged deficiencies or that approval of any of the
pending or subsequently submitted ANDAs by the Company will be forthcoming. In
addition, there can be no assurance that FDA, following the reinspection of
the Steris, Danbury and Marsam facilities and its review of their respective
responses to the alleged cGMP deficiencies, will not seek to impose additional
regulatory sanctions against the Company and its subsidiaries. See "--
Dependence Upon New Products and Effect of Product Lifecycles" and "Business--
Government Regulations."
 
 Consolidation of Distribution Network; Customer Concentration
 
  The Company's principal customers are wholesale drug distributors and major
drug store chains. These customers comprise a significant part of the
distribution network for pharmaceutical products in the United
 
                                      18
<PAGE>
 
States. This distribution network is continuing to undergo significant
consolidation marked by mergers and acquisitions among wholesale distributors
and the growth of large retail drug store chains. As a result, a small number
of large wholesale distributors control a significant share of the market, and
the number of independent drug stores and small drug store chains has
decreased. The Company expects that consolidation of drug wholesalers and
retailers will increase competitive pricing pressure on generic drug
manufacturers. The Company believes this consolidation has caused and may
continue to cause the Company's customers to reduce purchases of the Company's
products. In August 1997, Cardinal Health Inc. announced its intention to
merge with Bergen Brunswig Corporation. In addition, McKesson Corporation
announced its intention to merge with AmeriSource Corporation in September
1997. The pending mergers among the four largest pharmaceutical wholesalers in
the U.S., if consummated, would result in greater consolidation of the
pharmaceutical wholesaling industry and may intensify competitive pricing and
other competitive pressures on generic pharmaceutical manufacturers.
Specifically for Schein, if the Cardinal Health-Bergen Brunswig merger is
consummated, this combined customer would have accounted for approximately 33%
of the Company's total net revenues for the nine months ended September 1997.
 
  For the nine months ended September 1997, sales to the Company's ten largest
customers represented approximately 70% of the Company's total net revenues.
For 1996 and the nine months ended September 1997, three customers accounted
for 17%, 16% and 11%, respectively, of the Company's total net revenues. The
same three customers accounted for 16%, 15% and 11%, respectively, of the
Company's total net revenues in 1996. The loss of any of these customers could
materially and adversely affect the Company's business, results of operations
and financial condition. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business--Industry
Overview."
 
 Dependence on Collaborative Relationships
 
  The Company develops and markets certain products through collaborative
arrangements with other companies through which it gains access to dosage
forms, proprietary drug delivery technology, specialized formulation
capabilities and active pharmaceutical ingredients. The Company relies on its
collaborative partners for any number of functions, including product
formulation, approval and supply. There can be no assurance these products
will be successfully developed or that the Company's partners will perform
their obligations under these collaborative arrangements. Further, there can
be no assurance that the Company will be able to enter into future
collaborative arrangements on favorable terms, or at all. Even if the Company
enters into such collaborative arrangements, there can be no assurance that
any such arrangement will be successful. See "Business--Strategy" and
"Business--Strategic Collaborations."
 
 Supply of Raw Materials
 
  The principal components of the Company's products are active and inactive
pharmaceutical ingredients and certain packaging materials. Many of these
components are available only from a single source and, in many of the
Company's ANDAs, only one supplier of raw materials has been identified, even
in instances when multiple sources exist. Because FDA approval of drugs
requires manufacturers to specify their proposed suppliers of active
ingredients and certain packaging materials in their applications, FDA
approval of any new supplier would be required if active ingredients or such
packaging materials were no longer available from the specified supplier. The
qualification of a new supplier could delay the Company's development and
marketing efforts. Any interruption of supply could have a material adverse
effect on the Company's ability to manufacture its products or to obtain or
maintain regulatory approval of such products. In addition, the Company
obtains a significant portion of its raw materials from foreign suppliers.
Arrangements with international raw material suppliers are subject, among
other things, to FDA regulation, various import duties and other government
clearances. Acts of governments outside the U.S. may affect the price or
availability of raw materials needed for the development or manufacture of
generic drugs. In addition, recent changes in patent laws in jurisdictions
outside the U.S. may make it increasingly difficult to obtain raw materials
for research and development prior to the expiration of the applicable U.S.
patents. There can be no assurance that the Company will establish or, if
established, maintain
 
                                      19
<PAGE>
 
good relationships with its suppliers or that such suppliers will continue to
supply ingredients in conformity with legal or regulatory requirements. See
"Business--Strategy" and "Business--Manufacturing and Distribution."
 
 Risk of Product Liability Claims; No Assurance of Adequate Insurance
 
  The testing, manufacture and sale of pharmaceutical products involve a risk
of product liability claims and the adverse publicity that may accompany such
claims. The Company is a defendant in a number of product liability cases, the
outcome of which the Company believes should not materially and adversely
affect the Company's business, financial condition or results of operations.
Although the Company maintains what it believes to be an adequate amount of
product liability insurance coverage, there can be no assurance that the
Company's existing product liability insurance will cover all current and
future claims or that the Company will be able to maintain existing coverage
or obtain, if it determines to do so, insurance providing additional coverage
at reasonable rates. No assurance can be given that one or more of the claims
arising under any pending or future product liability cases, whether or not
covered by insurance, will not have a material adverse effect on the Company's
business, results of operations or financial condition. See "Business--Product
Liability; Insurance" and "Business--Legal Proceedings."
 
 Control of the Company
 
  Several of the Company's current principal stockholders are parties to the
Restructuring Agreements (as defined herein), one of which governs the voting
of their Common Stock until March 2000 and remains in effect until March 2000,
subject to earlier termination under certain circumstances. Upon such
termination, the stockholders who are parties to these agreements may be able
to control all matters requiring stockholder approval, including the election
of directors. The shares subject to these agreements represent a majority of
the shares of Common Stock to be outstanding immediately following the Equity
Offering. Under these agreements, the voting trustee (currently Martin
Sperber, the Chairman of the Board, Chief Executive Officer and President of
the Company), has the right to vote, or direct the vote of, the shares subject
to these agreements. As a result, Mr. Sperber will continue to control
substantially all matters requiring stockholder approval, including the
election of directors, following the Equity Offering.
 
  Bayer Corporation, which owns 28.3% of the outstanding shares of Common
Stock immediately prior to the Equity Offering, may purchase shares of the
Company up to a maximum, in the aggregate, of 30% of the Company's outstanding
Common Stock between May 15, 1997 and May 15, 1999, 33 1/3% between May 16,
1999 and May 15, 2000 and 36 2/3% between May 16, 2000 and May 15, 2001. Bayer
Corporation is a party to an agreement (the "Standstill") with the Company
that, among other things, prevents Bayer Corporation from acquiring or seeking
to acquire control of the Company prior to May 15, 2001. After such date,
Bayer Corporation has the right to acquire control through open market
purchases, and under certain circumstances within six months of the end of the
Standstill, to acquire from certain principal stockholders of the Company or
from the Company a number of shares that would enable Bayer Corporation to own
a majority of the outstanding shares of Common Stock. During the Standstill,
under the terms of the Restructuring Agreements, Bayer Corporation has the
right to acquire, including under certain circumstances the right to acquire
from the Company and certain of its principal stockholders, unless Bayer
Corporation has sold shares of Common Stock other than to certain permitted
transferees, (i) shares in connection with its exercise of certain preemptive
rights, (ii) after the Qualified Public Offering Date (as defined below) and
before May 15, 2001, shares necessary to acquire ownership of at least 21%
more of the outstanding Common Stock than any other holder of 10% or more of
the Common Stock (other than an employee benefit plan or a current
stockholder) (the "Investment Spread"), (iii) if, within 30 days after the
Qualified Public Offering Date, Bayer Corporation has the right to acquire
ownership of at least 21% more of the outstanding Common Stock than any other
holder of 10% or more of the Common Stock (other than a current stockholder or
employee benefit plan) and the total number of shares issued and outstanding
(less restricted securities, as defined therein) (the "Public Float") is less
than 133% of the Investment Spread, shares equal to the amount such Public
Float is less than 133% of the Investment Spread and

(iv) if, on May 15, 2001, the Public Float is less than 133% of the number of
shares that, when added to Bayer Corporation's shares, equals a majority of
the shares then outstanding, shares equal to such amount.
 
  As long as Bayer Corporation owns 10% or more of the outstanding Common
Stock (the "Governance Termination Date"), Bayer Corporation has the right to
nominate a number of members of the Board of Directors of the Company, rounded
down to the nearest whole number, (until Bayer holds more than 50% of the
outstanding Common Stock, then rounded up to the nearest whole number), equal
to the product of (a) the number of members of the Board of Directors and (b)
Bayer Corporation's percentage stockholding of Common Stock of the Company at
the time of nomination. Currently, Bayer Corporation has the right to nominate
one director and designate a second individual to attend Board meetings as an
observer.
 
  Until May 15, 2001, the Company may not undertake certain actions without
the consent of Bayer Corporation, including, among other things, (a) engaging
in any business not principally in a segment of the pharmaceutical or health
care industry (b) amending the Company's charter or by-laws to require more
than majority approval to elect a majority of the Board of Directors, or (c)
engaging in transactions with affiliates on terms more favorable to the
affiliate than could be obtained in arm's length transactions, other than
intercompany transactions and transactions under or identified in the
Restructuring Agreements. In addition, until the shares of the Company's
Common Stock held by more than 300 persons who are neither current
stockholders, their permitted transferees nor employees of the Company have a
total market value in excess of $100.0 million (the "Qualified Public Offering
Date"), the Company may not undertake certain other actions (including
incurring funded debt in excess of certain ratios, or declaring certain
dividends or making certain distributions in respect of the Company's Common
Stock) without the consent of Bayer Corporation.
 
  Each of the provisions described above may make it more difficult for a
third party to acquire, or may discourage acquisition bids for, Schein and
could limit the price that certain investors might be willing to pay in the
future for shares of the Common Stock. See "Principal Stockholders--
Restructuring Agreements."
 
 Fluctuating Results of Operations
 
  During the past three years, the Company's results of operations have
fluctuated materially on both an annual and a quarterly basis. These
fluctuations have resulted from several factors, including, among others, the
timing of introductions of new products by the Company and its competitors,
timing of receipt of patent settlement revenues, dependence by the Company on
a limited number of products, certain non-recurring expenses related to the
Company's restructuring and relocation in 1994, the Marsam Acquisition (as
defined herein) in 1995 and weak performance by the generic drug industry in
the second half of 1996 and continuing into the first half of 1997. The
Company believes that it will continue to experience fluctuations in net
revenues, gross profit and net income as a result of, among other things, the
timing of regulatory approvals and market introduction of new products by the
Company and its competitors, and downward pressure on pricing for generic
products available from multiple approved sources. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

                                  THE COMPANY
 
  The Company was founded in 1985. From 1992 to 1994, the Company engaged in a
series of corporate reorganization transactions, including the separation of
the Company from Henry Schein, Inc., a company engaged in the direct marketing
of health care products and services to office-based health care
practitioners, and the Company's reincorporation from New York to Delaware by
way of the merger of the Company's parent into the Company. In 1994, Bayer
Corporation purchased 28.3% of the Company's outstanding shares and agreed to
pursue future strategic alliances with the Company. In September 1995, the
Company acquired all the outstanding shares of Marsam, a developer,
manufacturer and marketer of generic injectable prescription drugs.
 
  The Company is a Delaware corporation with its corporate offices at 100
Campus Drive, Florham Park, New Jersey 07932. Its telephone number is (973)
593-5500.
 
                                USE OF PROCEEDS
 
  There will be no cash proceeds to the Company from the exchange pursuant to
the Exchange Offer. The net proceeds from the Initial Offering of $100.0
million were used to repay the Senior Subordinated Loan.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion and analysis should be read in conjunction with
"Selected Consolidated Financial Data" and the Consolidated Financial
Statements of the Company and Notes thereto included elsewhere in this
Prospectus. This Prospectus contains forward-looking statements that involve
risks and uncertainties, such as statements of the Company's plans,
objectives, expectations and intentions. The cautionary statements made in
this Prospectus should be read as being applicable to all related forward-
looking statements wherever they appear in this Prospectus. See "Risk
Factors."
 
OVERVIEW
 
  The Company currently manufactures and markets two classes of pharmaceutical
products, generic products and branded products. Generic products comprise the
Company's core products and patent review products and settlements resulting
from the Company's patent challenge activities. The Company's primary branded
product, INFeD, is the leading injectable iron product in the United States.
 
  The Company's results of operations depend on the Company's ability to
develop and commercialize new pharmaceutical products. Generally, following
the expiration of patents and any other market exclusivity periods for branded
drugs, the first pharmaceutical manufacturers successfully to market generic
equivalents of such drugs achieve higher revenues and gross profit from the
sale of such generic drugs than do others from the sale of generic equivalents
subsequently approved. As competing generic equivalents reach the market, the
prices, sales volumes and profit margins of the earliest generic versions
often decline significantly. For these reasons, the Company's ability to
achieve growth in revenues and profitability depends on its being among the
first companies to introduce new generic products. During the past five years,
the Company has introduced a significant number of generic products to the
market at patent expiration dates and in a number of cases prior to patent
expiration of the branded product by successful challenges to the patent under
the Waxman-Hatch Act.
 
  The Company's dependence on a limited number of products, the product cycles
of such products, and the timing of receipt of settlement revenues have
resulted in significant fluctuations in the Company's earnings. Continued
growth in the Company's revenues will depend on continued market demand for
its products, as well as the successful introduction and marketing of new
products.
 
  The development, manufacture, marketing and sale of pharmaceutical products
is subject to extensive federal, state and local regulation. The Company, like
other industry participants, must obtain approval from the FDA before
marketing most drugs, and must demonstrate continuing compliance with cGMP in
its production. Over the last several years, FDA has inspected various Company
manufacturing facilities. As a result of these inspections, FDA has required
that the Company modify certain of its manufacturing practices and, at times,
withheld approval of certain applications for new products, pending
satisfactory resolution of issues identified during the inspections. However,
all the Company's manufacturing facilities have continued production, and
there has been no significant impact on overall production. Certain
significant delays in the review or approval of applications for new products
could have a material adverse effect on the Company's future prospects. See
"Risk Factors--Pending Regulatory Matters" and "Business--Government
Regulations."
 
  The Company acquired all the outstanding capital stock of Marsam (the
"Marsam Acquisition") in September 1995 for $245.0 million in cash, which
expanded the Company's ability to manufacture sterile penicillins and oral and
sterile cephalosporins.

</TABLE>
 
  In 1992, the Company entered the branded pharmaceutical segment of the
market by introducing INFeD, currently the leading iron injectable product in
the U.S. Net revenues from INFeD as a portion of total net revenues increased
from 17% in fiscal 1995 to 20% in the nine months ended September 1997. Gross
profit margins on INFeD exceed gross profit margins on the Company's generic
products generally; accordingly, the gross profit from increased sales of
INFeD have offset the reduction in gross profit from generic products during
the periods presented.
 
  Product revenues and settlements have resulted from the Company's patent
challenge activities. Settlement revenues in fiscal 1995, 1996 and in the nine
months ended September 1997 reflect the receipt of funds from a pharmaceutical
company pursuant to an agreement reached by the Company in 1994. The agreement
provides that certain contingent payments may be made to the Company. The
Company expects a final payment of $30 million in the first quarter of 1998,
half of which will be paid to the Consultant. See Note 11 to the Consolidated
Financial Statements of the Company. In addition to the amounts paid to the
Consultant, the Company incurs other costs related to its patent review
activities as part of its overall product development activities.

NINE MONTHS ENDED SEPTEMBER 1997 COMPARED TO NINE MONTHS ENDED SEPTEMBER 1996
 
  Net revenues increased $1.6 million, or 0.5%, from $352.2 million in 1996 to
$353.8 million in 1997. In the branded business, sales increased $11.5
million, partially offset by a $9.9 million decline in the generic business.
The increase in branded product sales reflected largely an increase in units
sold. The decline in generic business resulted from (i) $32.4 million of price
erosion in core products and (ii) $16.7 million resulting from a strategic
decision in the second half of 1996 to discontinue certain lower-margin
manufacturing and lower-margin outsourced products, partially offset by a $6.4
million increase in sales of new products, an $18.5 million volume increase in
sales of core products and a $14.3 million increase in total patent review
revenues. The increase in patent review revenues resulted from a $11.5 million
increase in settlement revenues and a $2.8 million increase in sales of patent
review product revenues.
 
  Gross profit decreased $2.2 million, or 1.9%, from $115.5 million in 1996 to
$113.3 million in 1997. The gross margin decreased from 32.8% in 1996 to 32.0%
in 1997. The decline in gross profit was largely the result of price erosion
in core products, partially offset by increased gross margins from INFeD, new
products and an increase in settlement revenues.
 
  Selling, general and administrative expenses decreased $3.3 million, or
5.2%, from $63.3 million in 1996 to $60.0 million in 1997. Selling, general
and administrative expenses as a percent of net revenues decreased from 18.0%
in 1996 to 16.9% in 1997. The decrease in selling, general and administrative
expenses was due primarily to a reduction in the generic field sales force due
to consolidation of the customer base.
 
  Research and development expenses decreased $0.2 million, or 0.8%, from
$23.0 million in 1996 to $22.8 million in 1997. However, expenses in the third
quarter of 1997 increased compared to earlier 1997 quarters largely reflecting
costs associated with a development project nearing launch stage.
 
  Amortization of goodwill and other intangibles was unchanged compared to the
comparable period in 1996.
 
  As a result of the factors discussed above, operating income increased $1.4
million, or 6.5%, from $21.3 million in 1996 to $22.7 million in 1997.
 
  Interest expense, net, increased $4.4 million, or 27.2%, from $16.1 million
in 1996 to $20.5 million in 1997 principally due to higher amortization of
deferred financing expenses of $2.5 million and increased interest costs of
$1.5 million resulting from refinancing of senior debt with higher costing
subordinated debt in December 1996.
 
  Other expense (income), net, increased by $6.0 million from $0.5 million in
1996 to $6.5 million in 1997. Gains on the sale of marketable securities of
$9.9 million, primarily in the third quarter of 1997, offset increased equity
losses from the Company's investment in international joint ventures of $1.2
million and other expenses.
 
  The Company's effective tax rate is higher than the statutory rate due to
the effect of significant non-deductible expenses. The effective tax rate
decreased from 62.5% in 1996 to 57.8% in 1997, primarily as a result of higher
income offsetting fixed non-deductible expenses.
 
1996 COMPARED TO 1995
 
  Net revenues increased $84.5 million, or 21.6%, from $391.8 million in 1995
to $476.3 million in 1996. In the branded business, sales increased $21.0
million while generic business sales increased $63.5 million. The increase in
the branded product sales reflected largely an increase in units sold. The
increase in the generic business is primarily due to $32.2 million in sales
from the Marsam Acquisition in the third quarter of 1995, and a $20.3 million
increase in core product volume, partially offset by $15.0 million in price
erosion. Patent review
 
                                      28
<PAGE>
 
revenues increased $26.0 million, primarily due to a $17.5 million increase in
patent review product revenues and an increase in settlement revenues of $8.5
million.
 
  Gross profit increased $14.3 million, or 10.1%, from $141.3 million in 1995
to $156.6 million in 1996. The gross margin decreased from 36.1% in 1995 to
32.7% in 1996. The increase in gross profit was largely attributable to
increased revenues of INFeD, increases in patent review revenues and
settlement revenues and the full year of Marsam results, these increases are
partially offset by a price erosion in the core products.
 
  Selling, general and administrative expenses increased $12.0 million, or
15.9%, from $75.3 million in 1995 to $87.3 million in 1996, but decreased as a
percentage of net revenues from 19.2% in 1995 to 18.3% in 1996. Selling,
general and administrative expenses increased due primarily to increased sales
volume, the full year impact of the Marsam Acquisition of $2.6 million and an
increase in promotional activities in support of new product launches.
 
  Research and development expenses decreased $1.3 million, or 4.6%, from
$28.3 million in 1995 to $27.0 million in 1996. Acquired in-process Marsam
research and development charges of $30.0 million were fully reflected in
1995.
 
  Amortization of goodwill and other intangibles increased $6.8 million from
$3.4 million in 1995 to $10.2 million in 1996, giving effect to the full year
impact of the Marsam Acquisition.
 
  As a result of the factors discussed above, operating income increased $26.7
million from $4.3 million in 1995 to $31.1 million in 1996.
 
  Interest expense, net, increased $13.3 million from $10.0 million in 1995 to
$23.3 million in 1996. The increase was due primarily to the increase in
average debt associated with the financing for the Marsam Acquisition and
higher interest rates.
 
  Other expense (income), net, increased $2.4 million from income of $1.2
million in 1995 to an expense of $1.2 million in 1996. Equity losses from the
Company's investment in international joint ventures accounted for $3.1
million of the increase.
 
  The Company's effective tax rate is higher than the statutory rate due to
the effect of significant non-deductible expenses, which were largely
comprised of amortization of intangibles and the acquired in-process Marsam
research and development charge.
 
 1995 COMPARED TO 1994
 
  Net revenues increased $6.4 million, or 1.6%, from $385.4 million in 1994 to
$391.8 million in 1995. Branded business sales increased $6.1 million and
generic business sales increased $0.3 million. The increase in the branded
product sales reflected largely an increase in units sold. The increase in the
generic business is attributable to $14.0 million from the impact of the
Marsam Acquisition, $4.8 million of new product sales offset by a decrease in
other core products of $9.3 million and a decrease of $9.1 million of patent
review revenues. Patent review revenues decreased principally due to a decline
in patent review product revenues of $14.1 million, offset by settlement
revenues of $5.0 million.
 
  The Company's gross profit decreased $6.7 million, or 4.5%, from $148.0
million in 1994 to $141.3 million in 1995. The gross profit margin decreased
from 38.4% in 1994 to 36.1% in 1995. The decrease was primarily a result of
lower selling prices of patent review products and decreased gross margins on
core products revenues due to competitive pricing pressures. This was
partially offset by a $4.0 million increase representing the impact of the
Marsam Acquisition, an increase in gross margins in the Company's branded
business and decreased manufacturing and regulatory costs.
 
 
                                      29
<PAGE>
 
  Selling, general and administrative expenses increased $3.5 million, or
4.9%, from $71.8 million in 1994 to $75.3 million in 1995. Selling, general
and administrative expenses increased as a percentage of net revenues from
18.6% in 1994 to 19.2% in 1995. The increase in selling, general and
administrative expenses was due primarily to an increase in sales volume, an
increase in promotional activities in support of the Company's branded
business, new product launches and the Marsam Acquisition.
 
  Research and development expenses increased $9.1 million, or 47.8%, from
$19.2 million in 1994 to $28.3 million in 1995. Of the $9.1 million increase,
$2.1 million represented spending in connection with a worldwide technology
licensing and development agreement which the Company entered into during
September 1994, and the remaining increase in research and development
expenses was attributable to various new in-house development projects.
 
  Amortization of goodwill and other intangibles of $3.4 million and acquired
in-process Marsam research and development charges of $30.0 million in 1995
resulted from the Company's Marsam Acquisition in September 1995. See Note 3
to the Consolidated Financial Statements of the Company.
 
  The corporate reorganization and relocation were completed during 1994,
resulting in a $33.6 million charge. There were no restructuring or relocation
expenses incurred during 1995.
 
  As a result of the factors discussed above, operating income decreased $19.2
million from $23.5 million in 1994 to $4.3 million in 1995.
 
  Interest expense, net increased $8.5 million from $1.5 million in 1994 to
$10.0 million in 1995. The increase was due primarily to the increase in
average debt associated with the debt financing for the Marsam Acquisition
funded in September 1995.
 
  Other expense (income), changed by $1.5 from an expense of $0.2 million in
1994 to income of $1.3 million in 1995.
 
  The Company's effective tax rate is higher than the statutory rate due to
the effect of significant non-deductible expenses. The 1995 effective income
tax rate of 237.3% increased from the 1994 effective income tax rate of 69.6%,
primarily due to the impact of certain non-recurring and non-deductible
expenses, which were largely comprised of the acquired in-process Marsam
research and development charge of $30.0 million. The 1994 effective income
tax rate also reflects the impact of non-deductible expenses, primarily
special compensation charges in connection with the corporate reorganization
completed during 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Historically, the Company has financed its business operations primarily
through a revolving credit facility and used long-term bank financing to fund
acquisitions. The Company intends to finance future acquisitions through
either the issuance of new common shares and or the incurrence of new debt.
The incurrence of new debt is subject to certain limitations under the Senior
Credit Agreement and the Notes.
 
  Net cash provided by operating activities was $27.1 million and $10.8
million in the nine months ended September 1997 and in the year ended December
1996, respectively. The net cash provided by operating activities during 1997
was primarily attributable to net income, as adjusted for non-cash charges, of
$15.9 million and decreases in inventories and accounts receivable aggregating
$11.4 million. The net cash provided by operating activities during 1996 was
primarily attributable to net income, as adjusted for non-cash charges, of
$27.9 million and an increase in accounts payable and accrued expenses of
$11.9 million, offset by an increase in inventories and accounts receivable of
$31.0 million.
 
  Net cash provided by investing activities for the nine months ended
September 1997 and used in investing activities for the year ended December
1996 was $1.2 million and $20.0 million, respectively. Cash provided by
investing activities in 1997 resulted from the proceeds of sales of marketable
securities of $11.6 million, offset
 
                                      30
<PAGE>
 
primarily by capital expenditures, net of $9.0 million. The 1996 use of cash
in investing activities was primarily due to (i) capital expenditures, net,
(ii) purchase of product rights and licenses and, (iii) investments in
international joint ventures of $17.4 million.
 
  Net cash used in financing activities for the nine months ended September
1997 of $30.1 million resulted from the net repayment of debt. Net cash
provided by financing activities for the year ended December 1996 of $3.6
million was primarily due to net proceeds of debt.
 
  In September 1995, the Company entered into a secured revolving credit and
term loan agreement (as amended, the "Senior Credit Agreement") with a group
of banks to provide funds for the Marsam Acquisition, the repayment of certain
debt, working capital and general corporate purposes. The Senior Credit
Agreement, provided a term loan facility of $250.0 million and a revolving
credit facility of $100.0 million available through December 2001.
 
  The borrowings outstanding under the revolving credit facility were $30.0
million, $41.0 million and $26.0 million as of December 30, 1995, December 28,
1996 and September 27, 1997, respectively. Quarterly principal payments on the
term loan commence in September 1998 and end in the year 2001.
 
  In December 1996, the Company entered into an agreement for a $100.0 million
senior subordinated loan with a lead manager of the credit agreement.
Outstanding borrowings under the senior subordinated loan agreement bear
interest, payable quarterly, at a rate equal to LIBOR plus 4% or the bank's
floating base rate plus 3%, through January 31, 1998. Thereafter, the
principal amount of the loan will be increased to reflect related fees due and
will mature in five years. Interest will be due semi-annually and the interest
rate will be fixed at a new rate. The proceeds of the loan were used to prepay
principal on the term loan of the credit agreement. The effective borrowing
rate of the senior subordinated loan was 9.60% as of December 28, 1996. As a
result of this payment and scheduled payments, the term loan facility was
reduced to $130.0 million at September 1997.
 
  Borrowings under the credit agreement bear interest, which is payable at
least quarterly, at a rate equal to the bank's floating base rate plus a
premium ranging from zero to 1.50%, or at a rate equal to LIBOR plus a premium
ranging from 0.75% to 2.50%, depending on the type of borrowing and the
Company's performance against certain criteria. The effective borrowing rate
was 7.14%, 8.10% and $7.80% at December 30, 1995, December 28, 1996 and
September 27, 1997, respectively. A commitment fee ranging from 0.25% to 0.50%
per annum of the unused daily amount of the total commitment is payable
quarterly. The original obligation under the senior subordinated loan will be
effectively replaced by the Notes offered hereby. See "Description of Certain
Indebtedness."
 
  The Company has signed a non-binding letter dated October 7, 1997 with
Cheminor Drugs Limited and its subsidiaries ("Cheminor") and Dr. Reddy's
Laboratories Limited and its subsidiaries ("Reddy") outlining the parties'
intent to enter into a strategic alliance agreement. Cheminor will make
available to the Company its present and future dosage form generic products
on an exclusive basis in the United States and in certain countries, and the
Company will make available to Cheminor and Reddy its present and future
products on an exclusive basis for sale in India and certain other countries.
Cheminor and Reddy will make available to the Company bulk active
pharmaceutical ingredients. As part of the contemplated arrangement, the
Company would purchase 2.0 million publicly traded shares of Cheminor Drugs
Limited (12.79% of the presently outstanding shares of Clemson Drugs Limited)
for $10.0 million, and under certain circumstances have the right and the
obligation to purchase an additional 1.0 million shares for $5.0 million.
Cheminor would have the right to make fair market value purchases of the
Company's Common Stock, once the shares are publicly traded; the purchase
price could be payable from profits otherwise due Cheminor from the alliance.
Each party would also be entitled to representation on the other company's
board of directors consistent with its equity interest. See "Certain
Transactions."

  The Company has filed a registration statement covering the Equity Offering.
Consummation of each of this Exchange Offer and the Equity Offering is not
contingent upon consummation of the other. There can be no assurance that the
filing will become effective or that any shares will be sold. If the Common
Stock Offering occurs, the Company intends to use a portion of the net
proceeds from the Equity Offering to repurchase or redeem a portion of the
Notes offered hereby.
 
  In December 1997, the Company issued $100.0 million of Senior Floating Rate
Notes Due 2004 (the "Notes"), the proceeds of which were used to repay the
Senior Subordinated Loan. Interest on the Notes is payable quarterly at a rate
per annum equal to LIBOR plus 3%. The Notes will mature in December 2004,
unless previously redeemed. The Notes will be redeemable, in whole or in part,
at the option of the Company, at any time at the specified redemption prices.
Upon the occurrence of a change in control, each holder of Notes may require
the Company to repurchase such holder's Notes, in whole or in part, at a
repurchase price of 101% of the principal amount, plus accrued and unpaid
interest. The Equity Offering will not constitute a "change of control" under
the Notes. The Notes, which are unsecured obligations of the Company, rank
pari passu with or senior to all existing and future indebtedness of the
Company, and will rank senior in right of payment to all existing and future
indebtedness of the Company that is, by its terms, expressly subordinated to
the Notes.
 
  The Company believes that cash generated from its operations, its existing
credit facilities and the availability of $74.0 million under such facilities
as of September 1997 are sufficient to finance its current level of operations
and currently contemplated capital expenditures and strategic investments. In
the event the Company makes any significant acquisitions, it may be required
to raise additional funds, through the issuance of additional debt or equity
securities. There can be no assurance that such funds, if required, would be
available or, if available, would be on terms acceptable to the Company.

INFLATION
 
  Management does not believe inflation had a material adverse effect on the
financial statements for the periods presented.
 
EFFECT OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
  In June 1997, the Financial Accounting Standards Board issued two new
disclosure standards.
 
  Statement of Financial Accounting Standards No. 130 ("SFAS No. 130"),
Reporting Comprehensive Income, establishes standards for reporting and
display of comprehensive income, its components and accumulated balances.
Comprehensive income is defined to include all changes in equity except those
resulting from investments by owners and distributions to owners. Among other
disclosures, SFAS No. 130 requires that all items that are required to be
recognized under current accounting standards as components of comprehensive
income be reported in a financial statement that is displayed with the same
prominence as other financial statements.
 
  Statement of Financial Accounting Standards No. 131 ("SFAS No. 131"),
Disclosures about Segments of an Enterprise and Related Information, which
supersedes SFAS No. 14, Financial Reporting for Segments of a Business
Enterprise, establishes standards for the way that public enterprises report
information about operating segments in annual financial
 
                                      33
<PAGE>
 
statements and requires reporting of selected information about operating
segments in interim financial statements issued to the public. It also
establishes standards for disclosures regarding products and services,
geographic areas and major customers. SFAS No. 131 defines operating segments
as components of an enterprise about which separate financial information is
available that is evaluated regularly by the chief operating decision maker in
deciding how to allocate resources and in asserting performance.
 
  Both of these new standards are effective for financial statements for
periods beginning after December 15, 1997 and require comparative information
for earlier years to be restated. Results of operations and financial position
will be unaffected by implementation of these new standards. The Company has
not determined whether either of these two standards will have a material
impact on its financial statement disclosure.
 
RISK MANAGEMENT
 
  The Company is potentially subject to a concentration of credit risk with
respect to its trade receivables, the majority of which are due from
wholesalers, drug store chains and distributors. The Company performs ongoing
credit evaluations of its customers and generally does not require collateral.
The Company maintains sufficient allowances and insurance to cover potential
or anticipated losses for uncollectible accounts.
 
  The Company from time to time hedges a portion of its floating rate interest
exposure using various financial instruments. At September 1997, the Company
had no interest rate hedges in place.
 
  The Company considers its investment in international subsidiaries and joint
ventures to be both long-term and strategic. As a result, the Company does not
hedge the long-term translation exposure to its balance sheet. Foreign
currency translations to date have not been material.
 
YEAR 2000 COMPLIANCE
 
  The Company is modifying its computer systems to be Year 2000 compliant. The
Company does not expect that the cost of modifying such systems will be
material. The Company believes it will achieve Year 2000 compliance in advance
of the year 2000, and does not anticipate any material disruption in its
operations as the result of any failure by the Company to be in compliance.
The Company does not have any information concerning the Year 2000 compliance
status of its suppliers and customers.

                                   BUSINESS
 
GENERAL
 
  Schein Pharmaceutical is one of the leading generic pharmaceutical companies
in the United States. The Company develops, manufactures and markets one of
the broadest generic product lines in the pharmaceutical industry through the
integration of its product development expertise, diverse, high-volume
production capacity and direct sales and marketing forces. The Schein product
line includes both solid dosage and sterile dosage generic products, and the
Company is also developing a line of specialty branded pharmaceuticals. The
Company's primary branded product, INFeD, is the leading injectable iron
product in the United States. The Company has a substantial pipeline of
products under development, including 24 ANDAs filed with FDA. The Company
supplements its internal product development, manufacturing and marketing
capabilities through strategic collaborations. Schein generated net revenues
of $478.0 million and EBITDA of $61.1 million during the 12 months ended
September 1997.
 
  The Company believes it manufactures and markets the broadest product line
of any U.S. pharmaceutical company in terms of number and types of products.
The Company manufactures and markets approximately 160 chemical entities
formulated in approximately 325 different dosages under approximately 200
ANDAs approved by FDA. Schein is currently the sole manufacturing source for
47 generic pharmaceutical products, of which 45 are sterile dosage products.
The Company's solid dosage products include both immediate-release and
extended-release capsules and tablets; sterile dosage products include
solutions, suspensions, powders and lyophilized (freeze-dried) products
primarily for administration as injections, ophthalmics and otics. The
manufacture of sterile dosage products is significantly more complex than the
manufacture of solid dosage products, which limits competition in this product
area. The Company currently manufactures approximately four billion solid
dosage tablets and capsules and 75 million sterile dosage vials and ampules
annually. Solid dosage generic products and sterile dosage generic products
each accounted for approximately 40% of the Company's net revenues in the nine
months ended September 1997.
 
  Since introducing INFeD in 1992, the Company has been developing a portfolio
of branded products, primarily in select therapeutic markets, such as iron
management for the nephrology, oncology and hematology markets. INFeD is used
in the treatment of certain types of anemia, particularly in dialysis
patients, and accounted for approximately 20% of the Company's net revenues in
the nine months ended September 1997. The Company markets INFeD through a 20-
person dedicated sales and marketing force, as well as through co-marketing
collaborations with Bayer Corporation in the nephrology market and MGI in the
oncology market.
 
  The Company believes its 130-person direct sales and marketing force is one
of the largest in the U.S. generic pharmaceutical industry. Through its
customized marketing programs, the Company markets its products to
approximately 60,000 customers representing all major customer channels,
including pharmaceutical wholesalers, chain and independent drug retailers,
hospitals, managed care organizations, other group purchasing organizations
and physicians.
 
  Schein's objective is to become the leading generic pharmaceutical company
in the approximately $7.4 billion generic pharmaceutical industry in the
United States. The Company's growth strategy is to: (i) leverage its diverse
pharmaceutical formulation and manufacturing capabilities to extend the
breadth of its generic product line; (ii) focus its product development
activities on complex and other generic drugs that require specialized
development or manufacturing technology and are therefore expected to
encounter limited competition; (iii) develop and market branded drugs for
select therapeutic categories; (iv) pursue strategic collaborations to
supplement product development and manufacturing resources; and (v) expand
market penetration through direct sales and innovative marketing programs.
 
  The Company's commitment to product development has resulted in 23 ANDA
approvals during the past three years and its current pipeline of 24 pending
ANDAs and over 60 additional products under development. During the past three
fiscal years, the Company, directly and through its strategic collaborations,
has expended approximately $74.0 million on product pipeline development
activities, which the Company believes is among
 
                                      35
<PAGE>
 
the highest product development expenditure levels for any independent generic
drug company. The Company pursues product development through its 150-person
product development staff and various collaborations and licensing
arrangements with other pharmaceutical and drug delivery technology companies.
The Company's product development efforts focus on: (i) major branded drugs
coming off patent; (ii) drugs for which patent protection has lapsed and for
which there are few or no generic producers; (iii) drugs whose patents may be
susceptible to challenge; (iv) proprietary and branded products focused in
select therapeutic areas; and (v) generic products that require specialized
development, formulation, drug delivery or manufacturing technology.
 
  The Company supplements its internal product development, manufacturing and
marketing capabilities from external sources. During 1994, Schein entered into
a strategic alliance with Bayer Corporation, through which Bayer Corporation
became a 28.3% stockholder of Schein, and Bayer Corporation currently
participates with Schein in several collaborations. In 1995, the Company
acquired Marsam, expanding the Company's ability to develop and manufacture
sterile penicillins and oral and sterile cephalosporins. In addition, the
Company has entered into strategic collaborations involving product
development arrangements with companies such as Ethical and Elan; raw material
supply arrangements with companies such as Johnson Matthey and Abbott; and
sales and marketing arrangements with Bayer and other companies such as
Elensys and MGI.
 
INDUSTRY OVERVIEW
 
  In the U.S., pharmaceutical products are marketed as either branded or
generic. Branded products are marketed under brand names and through programs
designed to attract physician and consumer loyalty. Branded drugs generally
are covered by patents at the time of their market introduction, thereby
resulting in periods of market exclusivity for the patent holders. Following
the expiration of these patents, marketing of branded drugs often continues,
particularly in cases where there is significant physician or consumer
loyalty.
 
  Generic pharmaceuticals (also known as "multi-source" or "off-patent"
pharmaceuticals) are the chemical and therapeutic equivalents of branded
drugs. Under the Waxman-Hatch Act, generic drugs generally may be sold in the
United States following (i) FDA approval of an ANDA that includes evidence
that the generic drug is bioequivalent to its branded counterpart and (ii) the
expiration, invalidation or circumvention of any patents on the corresponding
branded drug and the expiration of any other market exclusivity periods
applicable to the branded drug.
 
  Since the adoption of the Waxman-Hatch Act, generic pharmaceuticals have
become an increasingly important segment of the U.S. pharmaceutical market,
particularly when measured in terms of the increasing rate at which doctors'
prescriptions have allowed generic drugs to be substituted for branded drugs.
In 1996, prescriptions dispensed in the United States for generic drugs
reached 40% of the total drug prescriptions dispensed. In terms of dollar
sales, however, generic drugs have accounted for a much lower percentage of
the total U.S. pharmaceutical market. In the 12 months ended September 1997,
sales of generic drugs accounted for approximately $7.4 billion out of a total
U.S. prescription pharmaceutical market of approximately $80.9 billion.
 
  The lower percentage of total dollar sales attributable to generic
pharmaceuticals compared to the growth in the number of generic pharmaceutical
prescriptions dispensed reflects the pricing dynamics for generic
pharmaceuticals. As the number of commercially available generic competitors
of a branded drug increases, their selling prices and gross margins decline
substantially. Generic drugs are generally sold at a 20% to 80% discount from
their branded counterparts. Intense price competition in the generic drug
industry requires companies to introduce new generic drug products regularly
in order to maintain and increase revenues.
 
  Growth of the generic drug industry has been driven primarily by the dollar
volume of branded drugs that have lost patent protection and the rising rate
at which generic drugs have been substituted for branded drugs. Industry
sources estimate that, during the next five years, branded drugs with 1996
U.S. sales of more than $13.0 billion will lose patent protection. The rising
rate of generic substitution has resulted in large part from increasing
pressure within the U.S. health care industry to contain costs. Due to the
lower cost of generic drugs compared to their branded counterparts, third
party payors, such as insurance companies, company health plans, health
maintenance organizations, managed care organizations, pharmacy benefit
managers, group purchasing
 
                                      36
<PAGE>
 
organizations, government-based programs and others, have adopted policies
that encourage or mandate generic substitution. In addition, physicians,
pharmacists and consumers are becoming increasingly comfortable with the
quality and therapeutic equivalence of generic drugs.
 
  A significant portion of pharmaceuticals are distributed in the United
States through wholesale drug distributors and major retail drug store chains.
During the past several years, there has been a consolidation of these
distribution channels, resulting in a smaller number of wholesale distributors
and the emergence of fewer, larger regional and nationwide retail drug store
chains. In addition to pressuring generic drug manufacturers to lower their
prices and/or provide volume discounts, these customers have also been seeking
to reduce the number of sources from which they purchase pharmaceutical
products.
 
  Participants in the generic drug market include independent generic drug
manufacturers such as the Company, generic drug subsidiaries of large branded
pharmaceutical companies and joint ventures and collaborations between branded
pharmaceutical companies and generic drug manufacturers. The participation of
branded pharmaceutical companies in the U.S. generic industry accelerated
during the first half of the 1990s as pricing pressure and generic
substitution grew. The extent to which the branded pharmaceutical companies
will continue to participate in the generic drug industry segment cannot be
predicted by the Company.
 
  The Company believes it is well positioned to capitalize on these industry
trends by leveraging its product development, manufacturing and marketing
capabilities to expand its market penetration.
 
STRATEGY
 
  The Company's objective is to become the leading generic pharmaceutical
company in the approximately $7.4 billion generic prescription pharmaceutical
industry in the United States. An important focus of the Company includes the
development, manufacture and marketing of complex generic products and branded
products for select therapeutic categories. The Company's strategy for
achieving this objective comprises the following five elements:
 
  Leverage Diverse Pharmaceutical Formulation and Manufacturing Capabilities
to Extend the Breadth of Its Generic Product Line. The Company believes it
manufactures and markets the broadest product line of any U.S. pharmaceutical
company. This product line includes both solid dosage and sterile dosage
products comprising approximately 160 chemical entities in approximately 325
dosage forms and strengths under approximately 200 approved ANDAs. Solid
dosage forms include both immediate-release and extended-release capsules and
tablets; sterile dosage forms include solutions, suspensions, powders and
lyophilized (freeze-dried) products primarily for administration as
injections, ophthalmics and otics. The Company believes its diverse high-
volume manufacturing capabilities enable it to participate in segments of the
generic drug industry where competition is limited. As the U.S. generic drug
market consolidates and major drug buyers increasingly purchase from fewer
suppliers, the Company believes its high volume and diverse drug formulation
and manufacturing capabilities will constitute an important competitive
advantage.
 
 
  Focus Product Development on Complex and Other Generic Drugs that Require
Specialized Development or Manufacturing Technology and Encounter Limited
Competition. The Company targets generic drugs for which it believes it can
achieve relatively high margins by being the first or among the first generic
manufacturers to launch the product. The Company is currently the sole generic
source for 47 products, and the Company is developing several "complex
generic" drugs that are difficult to duplicate due to formulation and/or
manufacturing complexities and other generic drugs for which raw materials are
in limited supply. In addition, the Company closely analyzes pharmaceutical
patents and initiates patent challenges where appropriate opportunities exist.
Products currently being considered for development include several that could
lead to patent challenges. The Company has generated significant revenues and
profits from generic products that have been the subject of successful patent
challenges initiated by the Company.
 
  Develop and Market Branded Drugs for Select Therapeutic
Categories. Leveraging its broad pharmaceutical formulation, development and
manufacturing capabilities, the Company targets branded drug
 
                                      37
<PAGE>
 
development and marketing opportunities in select therapeutic categories with
limited competition. The Company's branded drug development and marketing
efforts currently focus on injectable products used in the management of iron-
related disorders. The Company's first branded product, INFeD, is the leading
injectable iron product in the U.S. Schein's near-term development plan is to
expand the Company's iron management expertise into the oncology, hematology
and gastroenterology markets, and an NDA for its next generation injectable
iron product was filed with FDA in December 1997. The Company also is pursuing
opportunities to broaden its branded pharmaceutical product line by: (i)
formulating and developing, either internally or through development
collaborations, unique products that may be patented; (ii) acquiring products
developed by other drug companies; and (iii) acquiring formulation
technologies for developing new dosage forms of existing drugs.
 
  Pursue Strategic Collaborations to Supplement Product Development and
Manufacturing Resources. Schein has formed product development and marketing
alliances with several bulk pharmaceutical producers, drug delivery technology
companies and other drug manufacturers to expand the breadth of its product
development capabilities. Included among these are collaborations with drug
delivery companies, Elan and Ethical, and several bulk pharmaceutical and
finished dosage form producers. The Company plans to utilize collaborative and
licensing arrangements with third parties to share product development risk
and gain access to sales and marketing rights, dosage forms, proprietary drug
delivery technologies, specialized formulation capabilities and active
pharmaceutical ingredients.
 
  Expand Market Penetration through Direct Sales and Innovative Marketing
Programs. The Company believes its 130-person direct sales and marketing force
is one of the largest in the U.S. generic pharmaceutical industry. This sales
and marketing force includes 90 field representatives, 20 telemarketing
representatives and 20 marketing personnel and covers all major customer
groups, including chain and independent drug retailers, managed care
organizations, pharmaceutical wholesalers, hospitals and group purchasing
organizations. The Company has developed market share initiatives with
selected leading chain and wholesale customers and has implemented customized
marketing programs to meet specific customer needs, including customer
inventory management, patient-focused education and compliance programs. With
respect to its branded product business, the Company has a team of
approximately 20 sales representatives dedicated to marketing INFeD. This
sales and marketing force is complemented by marketing collaborations with
Bayer in the nephrology market and MGI in the oncology market.
 
PRODUCTS
 
  The Company believes it manufactures and markets the broadest number of
products of any U.S. pharmaceutical company in terms of number and types of
products. The Company's product line includes both solid dosage and sterile
dosage generic products; the Company is also developing a line of specialty
branded pharmaceuticals. The Company manufactures and markets approximately
160 chemical entities in approximately 325 dosage forms and strengths under
approximately 200 approved ANDAs. Schein is currently the sole generic source
for 47 pharmaceutical products.
 
  The following table sets forth the percentages of the Company's net revenues
attributable to its generic and branded businesses:

  During the period from 1993 to 1996, the Company's percentage of net
revenues from manufactured sterile dosage products and INFeD increased and the
percentage of net revenues from solid dosage products declined. This reflects
(i) the Company including Marsam's results (predominantly sterile dosage
products) since its acquisition by the Company in September 1995, (ii) INFeD
sales rising faster than the Company's total net revenues and (iii) older
solid dosage products experiencing declines in selling prices as competitors
have entered the market.
 
  GENERIC PRODUCTS
 
  The Company's generic business consists of the manufacturing and marketing
of sterile and solid dosage products and the marketing of certain additional
purchased products.
 
  The Company's manufactured sterile dosage product portfolio is comprised of
approximately 110 products and accounted for approximately 37% of the
Company's total net revenues in the nine months ended September 1997. This
portfolio includes vecuronium bromide, an anesthetic product that is currently
the Company's largest selling generic product, sales of which comprised
approximately 8.7% of the Company's total net revenues during this period. The
Company is manufacturing and marketing vecuronium bromide prior to expiration
of the patent covering this product pursuant to a licensing arrangement. None
of the Company's other sterile dosage products accounted for more than 6% of
net revenues in the nine months ended September 1997. Included in the sterile
dosage product portfolio are 45 products for which the Company is currently
the sole generic source, one of which is vecuronium bromide.
 
  The Company's manufactured solid dosage product portfolio is comprised of
approximately 50 products and accounted for approximately 30% of the Company's
total net revenues in the nine months ended September 1997. None of the
Company's solid dosage products accounted for more than 6% of net revenues in
the nine months ended September 1997. The Company's solid dosage portfolio
includes two products for which the Company is currently the sole generic
source.
 
  Pursuant to a custom manufacturing agreement dated as of July 1, 1995
between Johnson Matthey and the Company, the Company has exclusive purchase
and supply rights for bulk active methylphenidate hydrochloride produced by
Johnson Matthey. The agreement terminates on December 31, 2005, as amended,
with automatic renewals for additional successive three-year terms, unless
either party terminates the agreement on 24-months' prior notice.
 
  Pursuant to a product development, license and supply agreement dated August
16, 1994, as amended, between Elan and the Company, the Company has the right
to market, sell and distribute ketoprofen ER in the U.S. under Elan's ANDA.
Pursuant to the agreement, the Company has paid approximately $2.5 million in
development and license fees. Currently, the term of the agreement is 18 years
or, if longer, for the life of Elan's patents.
 
  The Company supplements its manufactured product line with purchased
products. The margins received by the Company on these products, however, are
generally lower than the margins received by the Company on products that it
manufactures. In addition, the Company believes its customers are increasingly
seeking to purchase products directly from manufacturers. The percentage of
the Company's total net revenues of generic products manufactured by others
has declined from approximately 18% in 1995 to 13% in the nine months ended
September 1997.
 
 
  BRANDED PRODUCTS
 
  Until 1992, the Company's exclusive focus was on generic pharmaceutical
products. In 1992, the Company introduced INFeD, its primary branded product,
and currently has other branded products under development. The Company
focuses on products used in the management of iron-related disorders.
Currently, INFeD, an injectable iron dextran used in the treatment of severe
anemia or iron deficiency, accounts for approximately
 
                                      39
<PAGE>
 
20% of the Company's net revenues. INFeD is most commonly used in the U.S. to
treat iron deficiency anemia in patients with end-stage renal disease who are
receiving therapy with recombinant human erythropoietin (EPO). In addition to
the dialysis market, the high incidence of iron deficiency anemia related to
other medical conditions presents further opportunities for the Company to
leverage its existing INFeD sales and marketing capabilities.
 
  The Company is seeking to expand its branded pharmaceutical business through
internal development and collaborative arrangements with other companies, with
a particular view to leveraging its expertise in iron management into the
nephrology, hematology and oncology markets. The following table identifies
the Company's branded product marketing and development activities:

  Iron Management Market
 
  In recent years, there has been increasing focus on improving the quality of
life of patients undergoing chronic disease therapy through, among other
means, iron management. The oxygen carrying component of red blood cells,
hemoglobin, requires iron to function efficiently. In some cases, iron
management requires the treatment of iron deficiency and, in other cases, the
treatment of iron overload disorders. The Company is currently marketing and
developing prescription products for the treatment of anemia in the dialysis
and oncology markets, and seeks to market INFeD for the gastroenterology and
bloodless medicine markets.
 
  Dialysis Market. The dialysis market is currently the largest market for
injectable iron and iron replacement products. Orally administered iron has
historically been, and continues to be, the first form of treatment used by
doctors to treat anemia in dialysis patients. Research has shown, however,
that orally administered iron inadequately treats iron deficiency in dialysis
patients and that injectable iron is more rapidly and directly absorbed in the
body. The National Kidney Foundation's Dialysis Outcome Quality Improvement
(DOQI) guidelines encourage more consistent use of injectable iron to
supplement the use of oral iron in dialysis patients. Approximately 60% to 65%
of dialysis patients are given injectable iron at least once a year. EPO
therapy is currently used to treat approximately 92% of all dialysis patients.
EPO allows patients to generate their own red blood cells, thus greatly
reducing the need for blood transfusions. One of the effects of EPO treatment,
however, is rapid mobilization of iron reserves and depletion of iron stores.
The Company believes that certain studies indicate that INFeD can be used
together with EPO to overcome this iron depletion effect. Accordingly, the use
of EPO therapy has created a need for iron management techniques.
 
  Oncology Market. In the oncology market, which includes patients with cancer
and cancer-related illnesses, anemia is a significant side effect of the
disease and the drugs used in treatment of the disease. Fatigue associated
with anemia is not widely recognized or treated as part of cancer treatment
regimens. Although there is a small base of injectable iron users in this
area, the Company believes there is potential for market expansion.
 
  Hematology and Gastroenterology. INFeD may also have applications in the
area of bloodless medicine. Bloodless medicine is surgery without the use of
blood infusions or transfusions; instead, plasma is supplemented with iron
that is administered to the patient before surgery to build up red blood cells
or after surgery to more rapidly replace red blood cells lost during surgery.
In the gastroenterology market, of the over one million patients with
inflammatory bowel disease, 30% to 70% experience anemia, mostly due to iron
deficiency.
 
  INFeD. INFeD (iron dextran injection, USP 50 mg/mL) is a liquid complex of
ferric hydroxide and dextran that is used in the treatment of patients with
documented iron deficiency in whom oral administration is
 
                                      40
<PAGE>
 
unsatisfactory or impossible. INFeD's product label includes the following
warning: "Warning: The parenteral use of complexes of iron and carbohydrates
has resulted in anaphylactic-type reactions. Deaths associated with such
administration have been reported. Therefore, INFeD (iron dextran injection,
USP 50 mg/mL) should be used only in those patients in whom the indications
have been clearly established and laboratory investigations confirm an iron-
deficient state not amenable to oral iron therapy."
 
  Currently, iron dextran is the only injectable iron formulation in the U.S.
market. The Company introduced its injectable iron product, INFeD, in May
1992. INFeD currently has approximately 85% of the injectable iron market, and
iron dextran products are marketed by one other company in the U.S. Net sales
of INFeD in 1996 and the nine months ended September 1997 were $88.0 million
and $72.1 million, respectively and accounted for 19% and 20%, respectively,
of the Company's net revenues. Growth in sales of INFeD has been driven by the
expanding use of EPO and the growing recognition of patient outcomes and
quality of life issues associated with iron deficiency anemia in dialysis
patients. For patients being treated with EPO, injectable iron therapy has
become adjunctive therapy rather than supportive therapy, as studies have
shown that anemic patients may become resistant to EPO and that injectable
iron can help to maintain EPO responsiveness and optimize its effectiveness.
The Company believes that the dialysis market should continue to expand with
the expected increase in the ESRD population, as well as the expanding use of
hemodialysis in the treatment of ESRD patients.
 
  Pursuant to a supply agreement dated May 1, 1992, as amended on December 2,
1993 and June 9, 1995, between Abbott and the Company, Abbott supplies iron
dextran bulk solution to the Company on an exclusive basis. The agreement
terminates on December 31, 1999. Abbott retains the right to manufacture,
sell, ship, market or distribute the finished iron dextran drug product,
provided the product is not manufactured with bulk solution or technology
relating to bulk solution obtained from Abbott or a licensee or sublicensee of
Abbott.
 
  Ferrlecit. Ferrlecit (sodium ferric gluconate complex in sucrose injection)
is intended to be the Company's next generation injectable iron product.
Ferrlecit is administered parenterally to treat hemodialysis patients with
iron deficiency anemia.
 
  Ferrlecit was developed by the Nattermann Company, of Cologne (now Rhone-
Poulenc Rorer GmbH) and is widely used in Europe. Makoff R&D Laboratories,
Inc. ("R&DL"), a specialty renal pharmaceutical company, acquired the rights
to Ferrlecit from Rhone-Poulenc Rorer GmbH under a distribution agreement
dated June 24, 1993 and a trademark agreement dated August 26, 1993. In 1996,
pursuant to an exclusive trademark and distribution agreement with R&DL, the
Company acquired from R&DL the exclusive right to market and distribute
Ferrlecit in the U.S. and several other countries for a period of ten years
after market authorization has been granted by FDA. R&DL filed its NDA in
December 1997. See "--Government Regulations--NDA Process."
 
  Other Products
 
  Nifedipine OD. In the U.K., the Company is currently marketing a branded
version of nifedipine OD , a once-a-day version of nifedipine used in the
treatment of hypertension. Pursuant to a license obtained from Ethical, this
product is being produced by a U.K. contract manufacturer. The Company is also
preparing for the product's launch in Israel, South Africa, the Caribbean and
selected markets in Latin America and Asia.
 
PRODUCT DEVELOPMENT
 
  The Company seeks to expand its product portfolio through continuing
investment in research and development. As a result of its approximately $74.0
million investment in product development over the past three fiscal years,
the Company has 24 ANDAs pending with FDA and over 60 products under
development internally and with third parties. The Company believes that this
increased level of investment in development activities should accelerate its
ANDA filings and launches in the next several years. The Company's product
development activities are conducted by 150 research and development
professionals and supported by others with expertise in manufacturing,
technology, legal, regulatory and intellectual property issues.
 
                                      41
<PAGE>
 
  The Company's generic product development efforts focus on: (i) major
branded drugs coming off patent; (ii) drugs for which patent protection has
lapsed and for which there are few or no generic producers; (iii) drugs whose
patents may be susceptible to challenge; (iv) proprietary and branded products
in select therapeutic areas; and (v) generic products that require specialized
development, formulation, drug delivery or manufacturing technology. In
furtherance of its strategy to be among the first to market generic versions
of brand drugs, the Company uses its scientific, pharmacologic, manufacturing
and legal expertise to identify brand products covered by patents that are
susceptible to challenge or circumvention. When the Company decides to pursue
development of a generic version of a brand product so identified, it seeks a
source for the drug's active pharmaceutical ingredient, develops a formulation
for the drug, conducts bioequivalence studies on its formulation (where
required) and prepares an ANDA filing. The ANDA filing must include a
certification from the Company that the patent on the brand product is invalid
or not infringed, and the patent holder must be provided with notice of the
filing and basis for the certification. If the patent holder commences
litigation within 45 days of the notice, FDA may not approve the ANDA for a
period of 30 months, unless the case is resolved earlier in court or by
settlement. A successful patent challenge may result in a court determination
that the patent on the brand product is invalid, not infringed or
unenforceable. Alternatively, a settlement with the patent holder may include
a license to the Company to sell the generic version of the brand product
prior to the expiration of the patent covering the product.
 
  Since 1985, the Company has had a series of non-exclusive agreements
(collectively, the "Consulting Agreement") with the Consultant. Under the
Consulting Agreement, the Consultant and the Company have identified certain
patents on branded pharmaceutical products that might be susceptible to a
challenge, and the Consultant has acted as litigation counsel or advising
counsel to the Company in those instances where the Company decided to proceed
with a patent challenge. For projects in which the Consultant has rendered an
opinion setting forth the basis for a possible patent challenge, the Company
pays the Consultant half the adjusted gross profit from the Company's sale of
generic versions of the patented product until the date on which the patent
would normally have expired or half the proceeds of any settlement.
 
  The Consultant's services are provided on a non-exclusive basis to the
Company. The Consulting Agreement does not have a specific term and continues
until the current projects under the Consulting Agreement are completed and
all payments due to the Consultant are made. There are two projects under the
Consulting Agreement, one of which has resulted in a pending patent challenge
initiated by the Company. In accordance with the Consultant's right to
delegate responsibility for defending patent challenge litigation to other
counsel selected with the consent of the Company, responsibility for the
pending patent challenge has been delegated to other counsel. The Consultant
may terminate the Consulting Agreement for certain specified reasons at any
time. Without regard to who terminates the Consulting Agreement or the reasons
therefor, the Consultant will be entitled to payment in conjunction with any
sales or settlements with respect to any patented product for which the
Consultant has previously rendered an opinion. The Consultant has rendered
opinions with respect to each of the two patented drug products that are the
respective subjects of the current projects under the Consulting Agreement,
and the Company will owe the Consultant payments to the extent that the
Company successfully develops one or both of these products and challenges the
applicable patents and thereafter markets one or both of these products, or
otherwise favorably settles any such challenge. See "Risk Factors--Dependence
on Successful Patent Litigation" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Results of Operations."
 
  In its branded product business, the Company intends to develop products for
the management of iron-related disorders and select other businesses, as well
as to promote the use of its primary branded product, INFeD, beyond the
dialysis market to other therapeutic areas, such as oncology and
gastroenterology.
 
STRATEGIC COLLABORATIONS
 
  To expand its product portfolio and improve its profitability, the Company
will continue to pursue strategic collaborations to access additional dosage
forms, proprietary drug delivery technology, specialized formulation
capabilities and sources of bulk active materials. The Company has product
development arrangements with
 
                                      42
<PAGE>
 
companies such as Ethical and Elan; collaborative arrangements for direct
access to raw materials with, among others, Johnson Matthey and Abbott; and
sales and marketing arrangements with companies such as Bayer Corporation,
Elensys and MGI. The Company has recently entered into a non-binding letter of
intent regarding Cheminor and Reddy. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Liquidity and Capital
Resources."
 
  The Company has signed a non-binding letter dated October 7, 1997 with
Cheminor and Reddy outlining the parties' intent to enter into a strategic
alliance agreement. As part of the contemplated arrangement, Cheminor could
purchase shares of the Company's Common Stock, once the shares are publicly
traded, at fair market value; the purchase price could be payable from the
profits otherwise due Cheminor from the alliance. Cheminor would have certain
rights to acquire additional shares from time to time, at fair market value,
to maintain its percentage interest in the Company. In addition, Cheminor
would have representation on the Company's Board of Directors consistent with
its equity investment through the purchase of the Company's shares once they
are publicly traded. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources" and "--
Products."

    Company.
 
  MANUFACTURING FACILITIES
 
  The Company's aggregate manufacturing capacity is among the largest of any
generic pharmaceutical company in the United States. The diversity and
capacity of these facilities are important elements of the Company's strategy
to expand the range of its existing product line and provide several
significant benefits, including (i) the ability to satisfy the growing
preference among many of the Company's customers for buying pharmaceuticals
directly from manufacturers and from fewer sources, (ii) added flexibility in
raw materials sourcing and manufacturing cost control, and (iii) economies of
scale with respect to manufacturing infrastructure functions common to solid
dosage manufacturing and/or sterile dosage manufacturing, such as water
distillation, air purification, drug formulation systems, filling and
packaging lines, and quality control and regulatory compliance. See "--
Strategy" and "--Government Regulations."
 
  The Company has made a substantial investment in plant and equipment and
believes that it is unique in its capacity to produce a broad line of both
sterile dosage products and solid dosage products. The Company
 
                                      43
<PAGE>
 
manufactures a variety of product forms and types, including immediate-release
and extended-release solid dosage products and sterile anti-infectives,
injectables, penicillins, cephalosporins, ophthalmics and otics. The Company
currently produces approximately four billion tablets and capsules and 75
million vials and ampules annually and has the capacity to increase production
to six billion tablets and capsules and 100 million vials and ampules
annually. This range of manufacturing capabilities allows the Company to
participate in segments of the generic industry where competition is limited.
Further, the Company's high-volume production enables it to obtain favorable
access to raw materials, which typically represent a substantial portion of
the cost of producing drug products. See "Risk Factors--Dependence on
Regulatory Approval and Compliance."
 
  The Company is one of only two U.S. generic manufacturers with dedicated
sterile filling facilities for cephalosporin and penicillin antibiotics, which
target the high volume institutional injectable market. In addition, the
Company's ophthalmic and otic drug manufacturing facilities target higher
margin specialty markets.
 
  In accordance with FDA requirements for manufacturers of finished
pharmaceutical products, the Company has developed strict quality control
procedures to ensure the quality and safety of its products. The Company
employs sanitary handling procedures, customized systems for monitoring and
regulating environmental conditions and back-up systems for many of the
critical steps in the production processes. The Company performs sample
testing of raw materials and packaging supplies used in manufacturing its
products and conducts on-site audits of raw material suppliers. In its
manufacturing process, the Company maintains strict quality control procedures
and believes it is in material compliance with FDA's cGMP standards. The
Company has approximately 380 employees dedicated to quality control and
quality assurance. Because developing and obtaining approval of new generic
products requires a large investment and several years of lead time, the
Company believes that companies like itself that have modern, versatile
manufacturing facilities will have a competitive advantage in responding to
market opportunities. See "Risk Factors--Dependence on Regulatory Approval and
Compliance," "Risk Factors--Pending Regulatory Matters" and "--Government
Regulations."
 
  The Company does not manufacture the active pharmaceutical ingredients used
in the preparation of its products. Instead, the Company purchases these
active pharmaceutical ingredients from international and domestic sources. FDA
requires pharmaceutical manufacturers to identify in their drug applications
the supplier(s) of all the raw materials for its products. If raw materials
for a particular product become unavailable from an approved supplier
specified in a drug application, any delay in the required FDA approval of a
substitute supplier could interrupt manufacture of the product, which could
materially and adversely affect the Company's profit margins and market share
for the product. To the extent practicable, the Company attempts to identify
more than one supplier in each drug application. However, in the case of
certain products (including certain products that contribute (or may
contribute) significantly to its sales and net income), the Company has
submitted drug applications that identify only one supplier. The Company has a
program of identifying alternative suppliers where practicable and, in many
cases, filing supplemental applications with FDA for approval.
 
  The Company obtains a significant portion of its raw materials from
international suppliers. Arrangements with international raw material
suppliers are subject, among other things, to FDA, customs and other
government clearances, various duties and regulation by the country of origin.
The Company has a number of collaborative arrangements for exclusive access to
some difficult to source products.
 
SALES AND MARKETING
 
  The Company believes that it has one of the largest direct sales and
marketing forces in the generic drug industry, with approximately 90 field
representatives, 20 telemarketing representatives and 20 marketing personnel.
This team is focused on enhancing pharmacist and payor knowledge of the Schein
product line and providing a differentiated level of customer service and
support. The sales and marketing force promotes Schein's newly approved
products and supports customers with innovative, value added services in
inventory management and patient education.
 
  The Company's broad customer base, which purchases from wholesalers and
directly from the Company, includes: retail customers, including chain drug
stores, mass merchandisers, food stores and independent drug
 
                                      44
<PAGE>
 
stores; wholesale distributors; managed care providers, including group
purchasing organizations, HMOs and mail order companies; alternative site
customers, such as long term care companies, home infusion companies and
surgery centers; and medical/surgical suppliers.
 
  Most pharmaceuticals today are sold through national and regional
wholesalers, who command approximately 80% of the U.S. drug distribution
market. While pharmaceutical products are typically distributed via these
wholesalers, pharmaceutical companies often directly enter into contracts with
the retail chains, managed care and institutional customers covering the
actual acquisition price. Under these arrangements, wholesalers often serve as
depots for substantially all of a customer's product needs, allowing it to
maintain minimal inventories and receive overnight deliveries of several
manufacturers' products from a single source. Currently, approximately 64% of
the Company's net revenues are sold through wholesalers, with approximately
82% of these net revenues subject to direct contracts between the Company and
its customers. In general, it is the Company's strategy to seek to enter into
purchase contracts with retail, managed care and institutional customers.
Sales to Bergen Brunswig Corporation, Cardinal Health, Inc. and McKesson Drug
Company accounted for 17%, 16% and 11%, respectively, of the Company's total
net revenues for the nine months ended September 1997.
 
  In August 1997, Cardinal Health Inc. announced its intention to merge with
Bergen Brunswig Corporation. In addition, McKesson Corporation announced its
intention to merge with AmeriSource Corporation in September 1997. The pending
mergers among the four largest pharmaceutical wholesalers in the U.S., if
consummated, would result in greater consolidation of the pharmaceutical
wholesaling industry and may intensify competitive pricing and other
competitive pressures on generic pharmaceutical manufacturers. Specifically
for Schein, if the Cardinal Health--Bergen Brunswig merger is consummated,
this combined customer would have accounted for approximately 33% of the
Company's total net revenues for the nine months ended September 1997.
 
  The vast majority of the Company's products are sold under the "Schein
Pharmaceutical," "Marsam Pharmaceuticals" and "Steris Laboratories" labels. In
addition, the Company sells a limited number of products to distributors under
private labels.
 
  The Company directs its sales and marketing activities through programs
specific to its generic product and branded product businesses.
 
  GENERIC PRODUCTS
 
  The Company has one of the largest generic sales and marketing organizations
in the U.S. generic pharmaceutical industry, with a sales and marketing
organization of 130 people serving the retail, institutional, alternative
site, managed care and other generic drug purchasing markets, including a 20-
person telemarketing sales force and 20 marketing personnel supporting the 90-
person field sales organization. The Company's large sales and marketing force
permits effective coverage of all purchasers of generic products. The sales
and marketing force promotes newly approved products, encourages substitution
of the Company's generic products for branded products and supports the
customer with value added services in inventory management and patient
education.
 
  The Company has developed market share initiatives with selected leading
chain and wholesale customers and has implemented customized marketing
programs to meet specific customer needs, including the following:
 
  .  The Company has implemented a unique vendor managed inventory program,
     Schein Pharmaceutical Managed Auto Replenishment Technology
     ("S.M.A.R.T."), which monitors customers' inventory levels daily to
     ensure adequate stocking levels, minimize the occurrence of back orders
     and returned goods and enhance inventory turnover for such key
     customers.
 
  .  The Company uses state-of-the-art electronic data interchange ("EDI")
     systems, which enable it to efficiently exchange data with its key
     wholesale and retail customers for a variety of transactions.
 
                                      45

  .  The Company offers a patient compliance program through which consumers
     receive prescription refill reminders from their pharmacies.
 
  .  The Company has designed the Generic Acceptance and Intervention Network
     ("G.A.I.N."), a patient-focused education program to promote the use of
     generic products.
 
  BRANDED PRODUCTS
 
  The Company has a sales and marketing organization of 20 people dedicated to
marketing INFeD. In 1994, the Company entered into a three-year co-promotion
arrangement with Bayer Corporation covering the Company's INFeD product. Under
this agreement, 16 of Bayer's specialty sales representatives in the United
States and Puerto Rico, on a full-time equivalent basis detail INFeD to the
nephrology market. In early 1998, this Agreement was extended to December
1998. In addition, as part of its marketing effort in the oncology market, the
Company entered into a co-promotion arrangement with MGI in March 1997 for
MGI's 21-person sales force to support INFeD in the oncology market.
 
COMPETITION
 
  In the generic pharmaceutical business, the Company competes with a number
of companies, including independent generic manufacturers and larger
pharmaceutical companies, which sell the same generic equivalents of the
Company's products. Many companies, including large pharmaceutical firms with
financial and marketing resources and development capabilities substantially
greater than those of the Company, are engaged in developing, marketing and
selling products that compete with those offered by the Company. The selling
prices of the Company's products may decline as competition increases.
Further, other products now in use or under development by others may be more
effective than the Company's current or future products. The pharmaceutical
industry is characterized by intense competition and rapid product development
and technological change. The Company's pharmaceuticals could be rendered
obsolete or made uneconomical by the development of new pharmaceuticals to
treat the indications addressed by the Company's products, technological
advances affecting the cost of production, or marketing or pricing actions by
one or more of the Company's competitors. The Company's business, results of
operations and financial condition could be materially adversely affected by
any one or more of such developments. Competitors may also be able to complete
the regulatory process for certain products before the Company and, therefore,
may begin to market their products in advance of the Company's products. The
Company believes that competition among prescription pharmaceuticals and
generics will be based on, among other things, product efficacy, safety,
reliability, availability and price. The Company believes that various
competitive factors, including pressure from major wholesalers and delays in
generic drug approvals by FDA, led to price declines beginning in mid-1996 for
generic drugs, largely offsetting growth in unit sales.
 
  From time to time, the Company may compete for the in-license or acquisition
of certain branded products with other pharmaceutical companies pursuing a
similar strategy. The Company's branded product competes with generic
pharmaceuticals which claim to offer equivalent therapeutic benefits at a
lower cost. In some cases, third-party payors encourage the use of lower cost
generic products by paying or reimbursing a user or supplier of a branded
prescription product a lower purchase price than would be paid or reimbursed
for a generic product, making branded products less attractive, from a cost
perspective, to buyers. The aggressive pricing activities of the Company's
generic competitors and the payment and reimbursement policies of third-party
payors could have a material adverse effect on the Company's business, results
of operations and financial condition.
 
GOVERNMENT REGULATIONS
 
  The research, development and commercial activities relating to branded and
generic prescription pharmaceutical products are subject to extensive
regulation by U.S. and foreign governmental authorities. Certain
pharmaceutical products are subject to rigorous pre-clinical testing and
clinical trials and to other approval requirements by FDA in the United States
under the Federal Food, Drug and Cosmetic Act (the "FDCA") and the Public
Health Services Act and by comparable agencies in most foreign countries.
 
 
                                      46
<PAGE>
 
  The FDCA, the Public Health Services Act, the Controlled Substances Act and
other federal statutes and regulations govern or influence all aspects of the
Company's business. Noncompliance with applicable requirements can result in
fines and other judicially imposed sanctions, including product seizures,
injunctive actions and criminal prosecutions. In addition, administrative or
judicial actions can result in the recall of products and the total or partial
suspension of the manufacturing of products, as well as the refusal of the
government to approve pending applications or supplements to approved
applications. FDA also has the authority to withdraw approvals of drugs in
accordance with statutory due process procedures. See "Risk Factors--
Dependence on Regulatory Approval and Compliance" and "Risk Factors--Pending
Regulatory Matters."
 
  FDA approval is required before any dosage form of any new unapproved drug,
including a generic equivalent of a previously approved drug, can be marketed.
All applications for FDA approval must contain information relating to product
formulation, stability, manufacturing processes, packaging, labeling and
quality control. In addition, acts of foreign governments may affect the price
or availability of raw materials needed for the development or manufacture of
generic drugs.
 
  ANDA PROCESS
 
  The Waxman-Hatch Act established abbreviated application procedures for
obtaining FDA approval for those drugs which are off-patent and whose non-
patent exclusivity under the Waxman-Hatch Act has expired and which are shown
to be bioequivalent to previously approved brand name drugs. Approval to
manufacture these drugs is obtained by filing an ANDA. An ANDA is a
comprehensive submission which must contain data and information pertaining to
the formulation, specifications and stability of the generic drug as well as
analytical methods and manufacturing process validation data and quality
control procedures. As a substitute for clinical studies, FDA requires data
indicating that the ANDA drug formulation is bioequivalent to a previously
approved NDA drug. In order to obtain an ANDA approval of a strength or dosage
form which differs from the referenced brand name drug, an applicant must file
and have granted an ANDA Suitability Petition. A product is not eligible for
ANDA approval if it is not bioequivalent to the referenced brand name drug or
if it is intended for a different use. However, such a product might be
approved under an NDA with supportive data from clinical trials.
 
  The advantage of the ANDA approval process is that an ANDA applicant
generally can rely upon bioequivalence data in lieu of conducting pre-clinical
testing and clinical trials to demonstrate that a product is safe and
effective for its intended use(s). The Company files ANDAs to obtain approval
to manufacture and market its generic products. No assurance can be given that
ANDAs or other abbreviated applications will be suitable or available for the
Company's products or that the Company's proposed products will receive FDA
approval on a timely basis, if at all. While the FDCA provides for a 180-day
review period, the Company believes the average length of time between initial
submission of an ANDA and receiving FDA approval is approximately two years.
 
  While the Waxman-Hatch Act established the ANDA, it has also fostered
pharmaceutical innovation through such incentives as market exclusivity and
patent restoration. The Waxman-Hatch Act provides two distinct market
exclusivity provisions which either preclude the submission or delay the
approval of a competitive drug application. A five-year marketing exclusivity
period is provided for new chemical compounds and a three-year marketing
exclusivity period is provided for applications containing new clinical
investigations essential to the approval of the application. The non-patent
market exclusivity provisions apply equally to patented and non-patented drug
products. Any entitlement to patent marketing exclusivity under the Waxman-
Hatch Act is based upon the term of the original patent plus any patent
extension granted under the Waxman-Hatch Act as compensation for reduction of
the effective life of a patent as a result of time spent by FDA in reviewing
the innovator's NDA. The patent and non-patent marketing exclusivity
provisions do not prevent the filing or the approval of an NDA. Additionally,
the Waxman-Hatch Act provides 180-day market exclusivity against effective
approval of another ANDA for the first ANDA applicant who (a) submits a
certificate challenging a listed patent as being invalid or not infringed and
(b) successfully defends in court any patent infringement action based on such
certification. The brand product segment of the pharmaceutical industry has
 
                                      47
<PAGE>
 
initiated legislative efforts to limit the impact of the Waxman-Hatch Act,
both on the federal and state levels. Recently, legislation has been
introduced designed to extend the patent protection on certain brand
pharmaceuticals and efforts have been made by the brand pharmaceutical
industry to introduce legislation to limit generic firms' ability to begin
research and development activities prior to patent expiration. In addition,
the brand product pharmaceutical companies have also initiated legislative
efforts in various states to limit the substitution of generic versions of
certain types of branded pharmaceuticals. The Company cannot predict whether
any such legislation will be enacted.
 
  NDA PROCESS
 
  An NDA is a filing submitted to FDA to obtain approval for a drug not
eligible for an ANDA and must contain complete pre-clinical and clinical
safety and efficacy data or a right of reference to such data. Before dosing a
new drug in healthy human subjects or patients may begin, stringent government
requirements for pre-clinical data must be satisfied. The pre-clinical data,
typically obtained from studies in animal species, as well as from laboratory
studies, are submitted in an Investigational New Drug ("IND") application, or
its equivalent in countries outside the United States, where clinical trials
are to be conducted. The pre-clinical data must provide an adequate basis for
evaluating both the safety and the scientific rationale for the initiation of
clinical trials.
 
  Clinical trials are typically conducted in three sequential phases, although
the phases may overlap. In Phase I, which frequently begins with the initial
introduction of the compound into healthy human subjects prior to introduction
into patients, the product is tested for safety, adverse effects, dosage,
tolerance, absorption, metabolism, excretion and other elements of clinical
pharmacology. Phase II typically involves studies in a small sample of the
intended patient population to assess the efficacy of the compound for a
specific indication, to determine dose tolerance and the optional dose range
as well as to gather additional information relating to safety and potential
adverse effects. Phase III trials are undertaken to further evaluate clinical
safety and efficacy in an expanded patient population at typically dispersed
study sites, in order to determine the overall risk-benefit ratio of the
compound and to provide an adequate basis for product labeling. Each trial is
conducted in accordance with certain standards under protocols that detail the
objectives of the study, the parameters to be used to monitor safety and the
efficacy criteria to be evaluated. Each protocol must be submitted to FDA as
part of the IND.
 
  Data from pre-clinical testing and clinical trials may be submitted to FDA
as an NDA for marketing approval and to foreign health authorities as a
marketing authorization application. The process of completing clinical trials
for a new drug is likely to take several years and require the expenditure of
substantial resources. Preparing an NDA or marketing authorization application
involves considerable data collection, verification, analysis and expense, and
there can be no assurance that approval from FDA or any other health authority
will be granted on a timely basis, if at all. The approval process is affected
by a number of factors, primarily the risks and benefits demonstrated in
clinical trials as well as the severity of the disease and the availability of
alternative treatments. FDA or other health authorities may deny an NDA or
marketing authorization application if the regulatory criteria are not
satisfied, or such authorities may require additional testing or information.
 
  Even after initial FDA or other health authority approval has been obtained,
further studies, including Phase IV post-marketing studies, may be required to
provide, for example, additional data on safety, and will be required to gain
approval for the use of a product as a treatment for clinical indications
other than those for which the product was initially tested. Also, FDA or
other regulatory authorities require post-marketing reporting to monitor
serious and unanticipated adverse effects of the drug. Results of post-
marketing programs may limit or expand the further marketing of the products.
Further, if there are any modifications to the drug, including changes in
indication, manufacturing process or labeling or a change in manufacturing
facility, an application seeking approval for such changes must be submitted
to FDA or other regulatory authority. Additionally, FDA regulates post-
approval promotional labeling and advertising activities to assure that such
activities are being conducted in conformity with statutory and regulatory
requirements. Failure to adhere to such requirements can result in regulatory
actions which could have a material adverse effect on the Company's business,
results of operations and financial condition.

  PENDING REGULATORY MATTERS
 
 
  In early 1996, FDA conducted an inspection of the operations of the
Company's subsidiary, Steris, located in Phoenix, Arizona. At the conclusion
of that inspection, FDA identified various cGMP manufacturing and reporting
deficiencies in Steris' operations. Steris was advised by FDA that it will not
approve any ANDAs for products manufactured at the Steris facility until FDA
confirms that the manufacturing and reporting deficiencies have been
corrected. Ten of the Company's pending ANDAs have been filed from the Steris
facility. Following the 1996 inspection, Steris implemented numerous measures
to correct these deficiencies and place Steris in compliance with applicable
FDA manufacturing and reporting requirements.
 
  In July 1997, FDA conducted a follow-up inspection of the Steris facility.
At the conclusion of that inspection, FDA identified additional cGMP
deficiencies at the Steris facility. Steris has implemented measures intended
to correct these deficiencies and believes that a full reinspection will be
required before FDA will approve ANDAs for new products manufactured at the
Steris facility. While the Company is currently discussing with FDA the timing
of this reinspection, no assurance can be given as to when it will take place.
Since the July 1997 inspection, Steris has provided FDA with information
concerning the completion of corrective action measures it has implemented and
the status of measures not yet completed. Recently, FDA requested that Steris
provide a time frame for completion of corrective action measures still in
progress. Steris intends to provide FDA with the information it has requested
and to seek a timely reinspection of its facilities. In early 1998, FDA issued
a Warning Letter relating to the deficiencies observed in the 1997 inspection.
 
  Following the 1996 inspection of Steris, FDA's Office of Regulatory Affairs
staff commenced an investigation of Steris' operations that focused primarily
on drug stability issues, including Steris' alleged failure to notify FDA on
an adequate and timely basis of drug stability problems with respect to
certain products manufactured at the Steris facility. On the basis of this
investigation, the DOJ notified Steris in a letter dated July 28, 1997 that
the alleged reporting deficiencies constituted serious breaches of regulatory
obligations and indicated that it would be willing to negotiate a settlement
of the alleged violations with Steris. On February 5, 1998, Steris entered
into a plea agreement, requiring Steris to pay a fine of $1.0 million and
pleading quilty to misdemeanor violations for failure to observe application
reporting requirements for two drugs during 1994 and 1995. While the Company
does not expect any other sanctions to arise in respect of this matter, any
such sanctions could have a material adverse effect on the Company's business,
results of operations and financial condition.
 
  In 1995, FDA inspected the operations of the Company's subsidiary, Danbury,
which operates facilities in Carmel, New York and Danbury, Connecticut. As a
result of observations made by FDA relating to Danbury's compliance with cGMP
requirements and the integrity of the data submitted by Danbury in support of
certain ANDAs, Danbury voluntarily audited all data submitted in connection
with 26 of its pending or approved ANDAs. Since the 1995 inspection, FDA has
continued to approve ANDAs for products manufactured by Danbury. From August
to October 1997, FDA reinspected Danbury's facilities. FDA observed certain
cGMP deficiencies which the Company has corrected in a manner satisfactory to
FDA. FDA is currently conducting an additional inspection of those facilities,
which involves primarily evaluations of the ANDA audits and the procedural
changes Danbury instituted to remedy cGMP deficiencies observed during the
1995 FDA inspection. During the course of the inspection, FDA has noted
deficiencies relating to certain testing records.
 
  In June 1997, FDA conducted an ANDA preapproval and cGMP inspection at the
Company's Marsam subsidiary, located in Cherry Hill, New Jersey. Although the
inspection focused primarily on issues relating to the manufacture of certain
drug products that are the subject of five pending ANDAs, the inspection also
included an examination of Marsam's general compliance with cGMP requirements.
Marsam was informed at the conclusion of the inspection that FDA intended to
withhold approval of the five ANDAs until certain alleged cGMP deficiencies
are corrected. Marsam has provided FDA with information it believes
demonstrates that the alleged deficiencies are not significant and that
corrective measures have been implemented. A follow-up inspection was
conducted to determine whether these corrective actions have been implemented
satisfactorily. Based upon the results of this inspection, FDA has informed
Marsam that its corrective actions are satisfactory
 
                                      49
<PAGE>
 
and that FDA is prepared to grant approvals of qualified ANDAs. Seven of the
Company's pending ANDAs have been filed from the Marsam facility.
 
  OTHER REGULATION
 
  The Prescription Drug Marketing Act (the "PDMA"), which amends various
sections of the FDCA, imposes requirements and limitations upon drug sampling
and prohibits states from licensing distributors of prescription drugs unless
the state licensing program meets certain federal guidelines that include,
among other things, state licensing of wholesale distributors of prescription
drugs under federal guidelines that include minimum standards for storage,
handling and record keeping. In addition, the PDMA sets forth civil and
criminal penalties for violations of these and other provisions. Various
sections of the PDMA are still being implemented by FDA and the states.
Nevertheless, failure by the Company's distributors to comply with the
requirements of the PDMA could have a material adverse effect on the Company's
business, results of operations and financial condition. See "Risk Factors--
Dependence on Regulatory Approval and Compliance" and "Risk Factors--Pending
Regulatory Matters."
 
  Manufacturers of marketed drugs must comply with cGMP regulations and other
applicable laws and regulations required by FDA, the Drug Enforcement Agency,
the Environmental Protection Agency and other regulatory agencies. Failure to
do so could lead to sanctions, which may include an injunction suspending
manufacturing, the seizure of drug products and the refusal to approve
additional marketing applications. Manufacturers of controlled substances are
also subject to the licensing, quota and regulatory requirements of the
Controlled Substances Act. Failure to comply with the Controlled Substances
Act and the regulations promulgated thereunder could subject the Company to
loss or suspension of those licenses and to civil or criminal penalties. The
Company seeks to ensure that any third party with whom it contracts for
product manufacturing or packaging will comply with cGMPs with which the
Company must also comply. FDA conducts periodic inspections to ensure
compliance with these rules. However, there can be no assurance that any such
third parties will be found to be in compliance with cGMP standards. Any such
non-compliance could result in a temporary or permanent interruption in the
development and testing of the Company's planned products or in the marketing
of approved products, as well as increased costs. Such non-compliance could
have a material adverse effect on the Company's business, results of
operations and financial condition.
 
  Products marketed outside the United States, which are manufactured in the
United States, are subject to certain FDA regulations as well as regulation by
the country in which the products are to be sold. The Company is required to
obtain approval for and maintain compliance with applicable regulations
relating to the marketing of its products outside the United States. There can
be no assurance that any such approval may be obtained or such compliance
maintained.
 
PRODUCT LIABILITY; INSURANCE
 
  The testing, manufacturing and distribution of the Company's products
involve a risk of product liability claims. Pursuant to the Company's various
insurance policies, the Company is self-insured up to the first $500,000 of
claims for each occurrence and $2,500,000 in the aggregate per policy year.
Although no assurance can be given, the Company believes that its product
liability insurance is adequate. Product liability insurance, however, could
cease to be available or could cease to be available on acceptable terms,
either as a function of the market for product liability insurance for
pharmaceutical companies or the Company's own claims experience. See "Risk
Factors--Risk of Product Liability Claims; No Assurance of Adequate
Insurance."
 
EMPLOYEES
 
  At December 1997, the Company had approximately 1,850 employees, of which
800 were engaged in manufacturing, 380 were engaged in quality control and
quality assurance, 250 were engaged in administration, finance and human
resources, 150 were engaged in research and product development, 150 were
engaged in sales and marketing, 80 were engaged in distribution and 40 were
engaged in regulatory affairs. No employee is
 
                                      50
<PAGE>
 
represented by a union, and the Company has never experienced a work stoppage.
Management believes its relationship with its employees is good.
 
LEGAL PROCEEDINGS
 
  The Company is a defendant in several product liability cases typical for a
company in the pharmaceutical industry. The Company also is involved in other
proceedings and claims of various types. Management believes the disposition
of these matters will not have a material adverse effect on the Company's
financial position, operations or liquidity.
 
  In October 1997, the Company received a subpoena from the Department of
Health and Human Services, Office of Inspector General seeking pricing
information for two products formerly marketed by the Company, vinblastine
sulfate and vincristine sulfate. The Company is aware of a number of other
pharmaceutical manufacturers and distributors that have been served with
similar subpoenas, which the Company believes is in connection with a
government investigation into claims for reimbursement by Medicare and/or
Medicaid. The Company has complied with the subpoena.

BOARD OF DIRECTORS
 
  The Board of Directors has five directors, three of whom--Martin Sperber,
Dariush Ashrafi and Paul Feuerman--are also officers of the Company and two of
whom--David R. Ebsworth and Richard L. Goldberg--are not officers of the
Company.
 
  The Company's certificate of incorporation that will be in effect upon the
completion of the Equity Offering divides the board of directors into three
classes, with each class holding office for staggered three-year terms. The
terms of one-third of the current directors will expire at the annual meeting
of stockholders in each of 1999, 2000 and 2001. At each annual election,
commencing at the annual meeting of stockholders in 1999, the successors to
the class of directors whose term expires at that time will be elected to hold
office for a term of three years to succeed those directors whose term
expires, so that the term of one class of directors will expire each year. The
classification of directors has the effect of making it more difficult to
change the composition of the Board of Directors in a relatively short period.
In addition, the classified board provision could discourage a third party
from attempting to obtain control of the Company, even though such an attempt
might be beneficial to the Company and its stockholders or could delay, defer
or prevent a change in control of the Company.
 
  Pursuant to the Restructuring Agreements (as defined herein), until Bayer
(as defined herein) owns less than 10% of the Company's outstanding Common
Stock, Bayer Corporation is entitled to nominate a number of members of the
Board of Directors of the Company, rounded down to the nearest whole number
(until Bayer holds more than 50% of the Company's outstanding stock, then
rounded up to the nearest whole number), equal to the product of (a) the
number of members of the Board of Directors and (b) its percentage
stockholdings of Common Stock at the time of nomination. In this regard, Bayer
Corporation nominated David R. Ebsworth as a member of the Board of Directors.
The Voting Trustee (currently Mr. Sperber) is entitled under the Restructuring
Agreements to nominate the balance of the members of the Board of Directors
until the Voting Trust Termination Date (as defined herein). Until May 15,
2001, the Voting Trustee and certain of the Company's principal stockholders
must vote for the election of Bayer Corporation's nominee(s). Until the Voting
Trust Termination Date, Bayer Corporation and certain of the Company's
principal stockholders must vote for the election of the Voting Trustee's
nominees.
 
  The Company's officers are elected by the Board of Directors for one-year
terms and serve at the discretion of the Board of Directors. See "Principal
Stockholders" and "Risk Factors--Control of the Company."
 
COMMITTEES OF THE BOARD OF DIRECTORS
 
  The Board of Directors of the Company has one standing committee: the
Compensation Committee.
 
  The Compensation Committee approves the compensation for senior executives
of the Company, makes recommendations to the Board of Directors with respect
to compensation levels and administers the Company's stock option plans. The
members of the Compensation Committee are Messrs. Ebsworth and Goldberg.
 
  The Company's Board of Directors is expected to appoint directors who are

EMPLOYMENT AGREEMENTS
 
  The Company entered into an employment agreement with Martin Sperber dated
September 30, 1994 pursuant to which Mr. Sperber serves as Chairman of the
Board, Chief Executive Officer and President of the Company. Under this
agreement, the term of Mr. Sperber's employment commenced on January 1, 1994
and terminates on January 1, 1999, unless earlier terminated by the death of
Mr. Sperber, by action of the Board of Directors with or without cause, due to
the disability of Mr. Sperber or by Mr. Sperber upon 30 days written notice or
a material breach by the Company of his employment or stock option agreement
that is not cured within 30 days. If Mr. Sperber is terminated without cause,
in addition to all accrued but unpaid compensation to the date of termination,
he is entitled to receive as severance compensation his base salary from the
date of termination through January 1, 1999 and an amount equal to the product
of (i) a fraction, the numerator of which is the amount of earned incentive
compensation for the last full year before termination and the denominator of
which is 365 and (ii) the number of days from termination until January 1,
1999. If Mr. Sperber voluntarily terminates his employment prior to January 1,
1999 (other than for an uncured breach by the Company), he is only entitled to
such severance pay as is determined by the Compensation Committee. Mr. Sperber
currently receives base annual compensation of $700,000. Mr. Sperber may also
receive incentive compensation in an amount to be determined by the
Compensation Committee. If Mr. Sperber's employment is terminated prior to
January 1, 1999, such incentive compensation shall be based on objective
criteria established by the Compensation Committee or $250,000 plus the
product of (x) the fraction derived by dividing (i) the sum of the actual cash
incentive compensation earned by each of the three most senior executives of
the Company other
 
                                      56

than Mr. Sperber in the year Mr. Sperber's employment is terminated less the
sum of the minimum cash incentive compensation contemplated for such
executives for such year, by (ii) the sum of the maximum cash incentive
compensation contemplated for such executives for such year less the sum of
the minimum cash incentive compensation contemplated for such executives for
such year and (y) $250,000. Mr. Sperber is prohibited from competing with the
Company during the term of the agreement and until the second anniversary of
the date the Company makes its final base salary payment to Mr. Sperber
pursuant to the agreement.
 
  Following termination of Mr. Sperber's employment other than for cause, Mr.
Sperber will be entitled during his lifetime and for the life of his spouse to
continue to participate in, or receive benefits that, on an after-tax basis,
are the same as those under all medical and dental benefit plans, policies and
programs in effect at the termination of his employment. In addition, unless
Mr. Sperber's employment is terminated for cause, Mr. Sperber will be entitled
to a pension, beginning after the termination of his employment and continuing
until the later of the death of Mr. Sperber or his spouse, in an amount equal
to 45% of the average total cash compensation for the highest three of the
last five years prior to termination, reduced generally by the sum of the
amount Mr. Sperber would be entitled to receive under all of the Company's

STOCK OPTIONS
 
  The Company's 1997 Stock Option Plan (the "1997 Plan") provides for the
granting of options to purchase not more than an aggregate of 3,370,200 shares
of Common Stock, subject to adjustment under certain circumstances. In
addition, the Company's 1993 Stock Option Plan (the "1993 Plan") provided for
the granting of options to purchase not more than an aggregate of 3,370,200
shares of Common Stock, subject to adjustment under certain circumstances. In
addition, the Company's 1995 Non-Employee Director Stock Option Plan (the
"Non-Employee Director Plan" and, together with the 1997 Plan and the 1993
Plan, the "Stock Option Plan") provides for the granting of options to
purchase not more than an aggregate of 123,000 shares of Common Stock, subject
to adjustment under certain circumstances. Although options granted under the
1993 Plan to purchase 3,109,194 shares are still outstanding, no further
grants will be made pursuant to the 1993 Plan. Some or all of the options
granted under the 1997 Plan may be "incentive stock options" within the
meaning of section 422 of the Internal Revenue Code of 1986 (the "Code"). The
Company has granted options to purchase 529,146 shares under the 1997 Plan at
the then fair market value and plans to grant     additional options to
purchase shares of Common Stock under the 1997 Plan prior to or at the
completion of the Equity Offering at an exercise price equal to the public
offering price.
 
  The Compensation Committee administers the 1997 Plan. The Compensation
Committee has full power and authority to interpret the 1997 Plan, set the
terms and conditions of individual options and supervise the administration of
the 1997 Plan.
 
  The Compensation Committee determines, subject to the provisions of the 1997
Plan, to whom options are granted, the number of shares of Common Stock
subject to an option, whether stock options will be incentive or non-
qualified, the exercise price of the options (which, in the case of non-
qualified options, may be less than the fair market value of the shares on the
date of grant) and the period during which options may be exercised. All
employees of the Company are eligible to participate in the 1997 Plan. No
options may be granted under the 1997 Plan after March 3, 2007.
 
  The Compensation Committee may amend the 1997 Plan from time to time.
However, the Compensation Committee may not, without stockholder approval,
amend the 1997 Plan to increase the number of shares of Common Stock under the
1997 Plan (except for changes in capitalization as specified in the 1997
Plan).
 
  The Non-Employee Director Plan provides for automatic annual grants of
options to purchase shares of the Company's Common Stock to non-employee
directors of the Company in amounts calculated using a formula provided in the
plan. The Company has granted options to purchase 26,445 shares of Common
Stock under the Non-Employee Director Plan and plans to grant 11,070
additional options to purchase shares of Common Stock under the Non-Employee
Director Plan to certain directors prior to or at the completion of the Equity
Offering.
 
  The Board of Directors of the Company may amend the Non-Employee Director
Plan from time to time. However, the Board of Directors may not, without
stockholder approval, amend the plan to increase the number of shares of
Common Stock available for option grants under the plan (except for changes in
capitalization specified in the plan).
 
CERTAIN OTHER EMPLOYEE BENEFIT PLANS
 
  The Company maintains The Retirement Plan of Schein Pharmaceutical, Inc. &
Affiliates (the "Company Retirement Plan"), under which employees (other than
temporary employees) of the Company may participate
 
                                      59
<PAGE>
 
on the first day of the first pay period after completing six consecutive
calendar months during which they complete at least 500 hours of service.
Effective July 1, 1996, the Company Retirement Plan became the successor to
the Marsam Pharmaceuticals Retirement Plan.
 
  Participants generally may make basic contributions to the Company
Retirement Plan, by salary deduction, of up to 14% of their compensation from
the Company, subject to applicable federal tax limitations ($10,000 for the
1998 plan year, subject to cost of living adjustments); the amount of a
participant's basic contribution is generally excluded from gross income for
federal or state income tax purposes. In 1998 the Company will make a
mandatory matching contribution to the Company Retirement Plan of $0.50 for
each dollar contributed to the Company Retirement Plan as a basic
contribution, up to the first 6% of a participant's contribution; the Company
also may make additional matching contributions and may make other non-
matching contributions to the Company Retirement Plan at the discretion of the
Board of Directors. In 1998, the Company will make a discretionary, non-
matching contribution under the Company Retirement Plan for 1997 equal to 5%
of compensation (as defined in the Company Retirement Plan).
 
  Participants in the Company Retirement Plan will be permitted to invest up
to 5% of their account balance in Common Stock at the Equity Offering price.
Participants will be allowed to sell their shares of Common Stock at any time,
however, they will not be permitted to purchase additional shares of Common
Stock at this time.
 
  Participants in the Company Retirement Plan have a 100% vested and
nonforfeitable interest in the value of their basic contribution and the
Company's matching contribution, and they acquire a 100% vested and
nonforfeitable interest in the Company's non-matching amounts at retirement,
death, disability or termination pursuant to an employee reduction plan. If
their employment terminates prior to the normal retirement date for any other
reason, participants acquire a 10% vested and nonforfeitable interest in the
Company's non-matching contribution amounts for each of the first four years
of service; and a 20% vested and nonforfeitable interest in the Company's non-
matching contribution amounts for each of the fifth, sixth and seventh years
of service; accordingly, after seven years of service, participants have a
100% vested and nonforfeitable interest in the value of the Company's non-
matching contribution amounts.
 
  Participants are entitled to receive the amounts in their Company Retirement
Plan accounts in a single lump-sum payment on death, disability, retirement or
termination of employment. At the election of the participant, the
participant's Company Retirement Plan account is eligible for payment in
installments of either 5 or 10 years. In certain circumstances, participants
may receive loans and hardship withdrawals from their accounts in the Company
Retirement Plan.
 
  Supplemental Retirement Plan. The Company maintains a Supplemental
Retirement Plan (the "Supplemental Retirement Plan"). Under the Supplemental
Retirement Plan, the Company pays non-qualified deferred compensation to
certain of its employees consisting of benefits based on annual compensation
in excess of limitations imposed by the Code on contributions under the
Company Retirement Plan. The Supplemental Retirement Plan is an unfunded
"pension benefit plan" subject to the Employee Retirement Income Security Act
of 1974, as amended.
 
  Split Dollar Life Insurance Plan. The Company maintains a Split Dollar Life
Insurance Plan (the "Life Insurance Plan"). Under the Life Insurance Plan,
each participating officer owns a life insurance policy. Each policy is
designed to provide at age 65 an annuity equal to a specified percentage of
the participant's projected average annual salary for the final three years of
employment (less Social Security benefits and certain benefits under the
Company Retirement Plan and Supplemental Retirement Plan). A cash surrender
value, which is owned by the individual and designed to fund the annuity,
accumulates under each participant's policy. The Company and the employee will
share the cost of premiums. The premiums advanced by the Company will be
repaid out of the cash value of the policies or the proceeds of the death
benefits.
 
  1993 Book Equity Appreciation Rights Program. The Company maintains a Book
Equity Appreciation Rights Program (the "Program") to allow certain employees
to benefit from an increase in the Company's book
 
                                      60
<PAGE>
 
value (calculated according to a formula defined in the Program). All
participants are fully vested in their book equity appreciation rights
("BEARs"). The Company does not intend to make any additional grants of BEARs.
 
  1998 Employee Stock Purchase Plan. The Company adopted an Employee Stock
Purchase Plan on January 23, 1998, which provides employees an opportunity to
purchase stock of the Company through payroll deductions upon completion of
the Equity Offering. Employees may elect to withhold from 1% to 20% of their
compensation and purchase Common Stock directly from the Company. Each
employee's annual purchase is limited to Common Stock with a fair market value
of $25,000 per year, which Common Stock will be purchased at 85% of the fair
market value of the Stock. The maximum number of shares of the Company's
Common Stock available for purchase under the plan is 500,000 shares.

                             CERTAIN TRANSACTIONS
 
  In 1994, the Company entered into a Heads of Agreement with Bayer
Corporation and Bayer A.G. (collectively, "Bayer"), pursuant to which the
Company and Bayer committed together to explore business opportunities for the
U.S. and abroad. Under the agreement, the parties agreed to share expertise,
personnel, products and production facilities where appropriate to (i) explore
potential areas of mutual interest and cooperation in the U.S. domestic
market, (ii) identify multisource pharmaceutical business opportunities abroad
and (iii) explore the use of Bayer's chemical synthesis expertise to provide
the Company with chemical drug ingredients. The agreement provides that any
decision to pursue a project must be approved by both parties and based on a
separately negotiated contractual agreement.
 
  In 1994, the Company entered into a three-year co-promotion agreement with
Bayer Corporation covering the Company's INFeD product. Under the terms of the
agreement, during the periods from 1994 to 1997 in exchange for promotional
support, the Company shared with Bayer the net profits of INFeD in excess of
specified threshold amounts. In early 1998, this agreement was amended and
extended to December 1998. This amended agreement provides that in exchange
for promotional support, the Company pays Bayer Corporation a fixed dollar
amount plus a fixed percentage of sales above a threshold amount. The Company
incurred selling expenses under these agreements of approximately $3.0 million
in 1996. There were no selling expenses under the first agreement for 1995.
See "Principal Stockholders."
 
  Since 1994, the Company and Bayer, through their respective affiliates, have
entered into several joint ventures to own, manage or develop generic
pharmaceutical businesses outside of the U.S. Each of Schein and Bayer have
contributed various assets and rights and funded the operations of these
ventures, and in certain circumstances have guaranteed certain liabilities of
these ventures, such as leases and lines of credit. It is contemplated that
the Company and Bayer will sell products to certain of these ventures for
resale in their local markets.
 
  During 1995 and 1996, the Company invested approximately $3.5 million and
$2.0 million, respectively, to acquire up to a 50% interest in each of several
international pharmaceutical businesses. These businesses are jointly owned
with subsidiaries of Bayer AG, the parent of Bayer Corporation, a minority
investor in the Company. The Company recorded losses of approximately $0.3
million and $3.4 million in 1995 and 1996, respectively, as its share of the
operating results of these businesses. The Company generally anticipates that
these international businesses will not have significant revenues or
operations for a period of two to three years, during which time the
businesses incur expenses to register products in anticipation of future
sales. The Company incurred expenses of approximately $2.1 million and $2.9
million in 1995 and 1996, respectively, to identify, evaluate, and establish
these and other potential international business ventures. Each of Bayer and
Schein currently is evaluating the extent of its continued participation in
certain of these ventures.
 
  In 1997, the Company, together with the Pharmaceutical, Consumer Healthcare,
Afga Film and Diagnostics divisions of Bayer Corporation, has created a
collaboration called Bayer Healthcare Partners. Bayer Healthcare Partners is a
marketing tool through which the various participants combine their sales
efforts to offer a package of goods and services designed to be more
attractive to a customer, most likely a managed healthcare provider. The
participants share in the costs and profits associated with sales of the
covered products to the customer. In the last six months of 1997, the Company
incurred expenses of approximately $100,000.
 
  In the conduct of its business, the Company sells pharmaceutical products to
Henry Schein, Inc. for distribution to its customers. Net sales to Henry
Schein, Inc. were $6.4 million, $5.3 million and $8.6 million in 1994, 1995
and 1996, respectively. Certain of the Company's principal stockholders also
are principal stockholders of Henry Schein, Inc. All transactions between the
Company and Henry Schein, Inc. are on an arm's-length basis.

  In connection with Mr. Ashrafi's relocation, the Company loaned Mr. Ashrafi
$150,000 at an interest rate of 6.875% per annum evidenced by a promissory note
dated May 31, 1996. As of September 1997, an aggregate principal amount of
$150,000 was outstanding on that loan.

  Restructuring Agreements
 
  At the time of Bayer Corporation's acquisition of its 28.3% interest in the
Company, the Company, Bayer Corporation, Mr. Sperber, and certain other
principal stockholders entered into certain agreements (the "Restructuring
Agreements") relating to the governance of the Company and certain other
matters.
 
  Agreements Relating to Control of the Company. The Restructuring Agreements
provide that, until the earlier of March 1, 2000 and the effective date of a
merger, consolidation or combination that results in the Voting Trustee
(currently Mr. Sperber) (the "Voting Trustee") neither holding the position of
chairman of the board, president, chief executive officer or chief operating
officer of the resulting entity nor having the right to designate a majority
of the members of the board of the resulting entity (such earlier date, the
"Voting Trust Termination Date"), the Voting Trustee will have the right to
vote, or direct the vote of, all the shares of Common Stock owned by Marvin
Schein, Pamela Schein and Pamela Joseph and certain trusts established by them
or for their issue (collectively, the "Family Stockholders") (i.e.,    % of
the outstanding shares of Common Stock immediately after the completion of the
Equity Offering, assuming the Underwriters' over-allotment option is not
exercised). As a result of the foregoing, the Voting Trustee as a practical
matter will be able to control substantially all matters requiring stockholder
approval, including the election of directors, until March 1, 2000 (without
giving effect to any future public issuance of Common Stock by the Company or
sales of Common Stock by Continuing Stockholders). The Restructuring
Agreements provide that Mr. Sperber may designate certain individuals to
succeed him as Voting Trustee under the Restructuring Agreements.
 
  The Restructuring Agreements provide that, until the Governance Termination
Date, Bayer Corporation shall be entitled to nominate a number of members of
the Board of Directors of the Company, rounded down to the nearest whole
number (until Bayer holds more than 50% of the outstanding Common Stock, then
rounded up to the nearest whole number), equal to the product of (a) the
number of members of the Board of Directors and (b) its percentage
stockholdings of Common Stock of the Company at the time of nomination. The
Voting Trustee is entitled, until the Voting Trust Termination Date, to
nominate the balance of the members of the Board of Directors. Until May 15,
2001, the Voting Trustee and the other Continuing Stockholders (as defined
herein) (to the extent their shares of Common Stock are not voted by the
Voting Trustee) must vote for the election of Bayer Corporation's nominee(s).
Until the Voting Trust Termination Date, Bayer Corporation and the Continuing
Stockholders (to the extent their shares of Common Stock are not voted by the
Voting Trustee) must vote for the election of the Voting Trustee's nominees.
 
  Until the earlier of May 15, 2001 and a sale of shares by Bayer Corporation
other than to a Permitted Assignee (as defined herein), the Company may not,
without Bayer Corporation's consent, among other things, (a) own, manage or
operate any business not principally engaged in a segment of the
pharmaceutical or health care industry or any business ancillary thereto, (b)
amend or restate the Company's charter or by-laws to require more than
majority approval to elect a majority of the Board of Directors, or (c) engage
in transactions with any affiliate on terms more favorable to the affiliate
than could be obtained in an arm's-length transactions, other than
intercompany transactions and transactions under or identified in the
Restructuring Agreements. In addition, until the earlier of (i) the Governance
Termination Date, (ii) the Qualified Public Offering Date and (iii) a sale of
shares by Bayer Corporation other than to a Permitted Assignee, the Company
may not undertake certain other actions (including incurring funded debt in
excess of certain ratios or declaring certain dividends or making certain
distributions in respect of the Company's Common Stock) without the consent of
Bayer Corporation.
 
  The Restructuring Agreements include the Standstill, which imposes certain
restrictions on Bayer Corporation and its affiliates until May 15, 2001 (the
"Standstill Period"). During the Standstill Period, Bayer Corporation and its
affiliates may not among other things (a) acquire, announce an intention to
acquire or offer to acquire any assets of the Company or its subsidiaries
(other than in the ordinary course) or equity securities of the Company, (b)
participate in or encourage the formation of a group or entity that seeks to
acquire equity securities of the Company, (c) solicit proxies or become a
participant in any election contest with respect to the Company, (d) initiate
or otherwise solicit stockholders for the approval of stockholder proposals or
induce any
 
                                      65
<PAGE>
 
other person to initiate any stockholder proposal, (e) seek to place designees
on, or remove any member of, the Board or Directors, (f) deposit any equity
securities in a voting trust or like arrangement, (g) seek to control the
management of the Company or negotiate with any person with respect to any
form of extraordinary transaction with the Company or other transaction not in
the ordinary course of business, or be involved in a tender or exchange offer
or other attempt to violate the Standstill or (h) request the Company or
otherwise seek to amend or waive any provision of the Standstill. In addition,
until the Qualified Public Offering Date, the Company may not undertake
certain other actions (including incurring funded debt in excess of certain
ratios or declaring certain dividends or making certain distributions in
respect of the Company's Common Stock) without the consent of Bayer
Corporation.
 
  After the Standstill Period, Bayer Corporation has the right to acquire
control through open market purchases, and under certain circumstances within
six months of the end of the Standstill Period, to acquire from certain
principal stockholders of the Company or from the Company a number of shares
that would enable Bayer Corporation to own a majority of the outstanding
shares of Common Stock. During the Standstill Period, under the terms of the
Restructuring Agreements, Bayer Corporation has the right to acquire,
including under certain circumstances the right to acquire from the Company
and certain of its principal stockholders unless Bayer Corporation has sold
shares of Common Stock other than to certain permitted transferees, (i) shares
in connection with its exercise of certain preemptive rights, (ii) after the
Qualified Public Offering Date (as defined below) and before May 15, 2001,
shares necessary to acquire the Investment Spread, (iii) if, within 30 days
after the Qualified Public Offering Date, Bayer Corporation has the right to
acquire ownership of at least 21% more of the outstanding Common Stock than
any other holder of 10% or more of the Common Stock (other than a current
stockholder or employee benefit plan) and the Public Float is less than 133%
of the Investment Spread, shares equal to the amount such Public Float is less
than 133% of the Investment Spread and (iv) if, on May 15, 2001, the Public
Float is less than 133% of the number of shares that, when added to Bayer
Corporation's shares, equals a majority of the shares then outstanding, shares
equal to such amount. Notwithstanding the foregoing, Bayer Corporation may
purchase additional shares up to a maximum, in the aggregate, of 30% of the
Company's outstanding Common Stock between May 15, 1997 and May 15, 1999, 33
1/3% between May 16, 1999 and May 15, 2000 and 36 2/3% between May 16, 2000
and the end of the Standstill Period.
 
  Under the Reorganization Documents, if Bayer Corporation for any reason
acquires shares in excess of the New Percentage, until May 15, 2001, Bayer
shall vote those excess shares in accordance with the Voting Trustee's
instructions and those excess shares will not be considered in determining the
number of director nominees to which Bayer Corporation is entitled.
 
  Under the Restructuring Agreements, each of Marvin Schein, Pamela Schein and
Pamela Joseph has agreed that such individual, and such individual's Family
Group, shall not acquire shares if, as a consequence of the acquisition such
individual, together with such individual's Family Group (as defined herein),
owns in excess of (a) in the case of Marvin Schein and his Family Group,
35.85% of the Common Stock, (b) in the case of Pamela Schein and her Family
Group, 27.55% of the Common Stock and (c) in the case of Pamela Joseph and her
Family Group, 12.97% of the Common Stock.
 
  Restrictions on Transfer. The Restructuring Agreements generally provide
that Marvin Schein, Pamela Schein, Pamela Joseph, Mr. Sperber, Stanley
Bergman, certain trusts established by these individuals (collectively, the
"Continuing Stockholders") and certain of their transferees may not transfer
any of their shares of Common Stock until March 1, 2000, except (a) pursuant
to Rule 144 under the Securities Act, but subject to volume limitations
intended to equal the volume limitations applicable to affiliates as set forth
in Rule 144(e)(1) (the "Maximum Rule 144 Sales Amount"), (b) in a wide
distribution in an amount that exceeds the Maximum Rule 144 Sales Amount,
regardless of whether the seller is an affiliate or Rule 144(k) is applicable,
in connection with which the seller or the underwriter confirms that no direct
or indirect purchaser in that distribution is intended to acquire more than
the Maximum Rule 144 Sales Amount, (c) to certain family members of the
transferor, related trusts or estates, or other entities owned exclusively by
such transferor, family members, trusts or estates (collectively, a "Family
Group"), (d) in private placements, to persons who own fewer than 1% of the
outstanding Common Stock immediately prior to the transfer and who are not
affiliated with or Family Group members of the transferor, of no more than (I)
1% of the outstanding Common Stock to any one person, its
 
                                      66
<PAGE>
 
affiliates or Family Group members in any three-month period and (II) 4% of
the outstanding Common Stock to all persons in any twelve-month period, (e) in
connection with the exercise of certain registration rights granted to the
Company's stockholders under the Restructuring Agreements, but only if, to the
extent the number of shares sold exceeds the Maximum Rule 144 Sales Amount, it
is confirmed to the Company that it is intended that no purchaser will acquire
more than the Maximum Rule 144 Sales Amount, (f) pledges to a financial
institution or transfers to a financial institution in the exercise of its
pledge rights, (g) to Bayer Corporation as provided under the Restructuring
Agreements, (h) pursuant to a merger or a consolidation that has been approved
by the Board of Directors and stockholders of the Company, (i) in a tender
offer in which Mr. Sperber (or any member of his Family Group who acquired
shares from Mr. Sperber) sells shares and (j) in a tender offer for a majority
of the shares of Common Stock of the Company by a bidder not affiliated with
Bayer Corporation, if Bayer Corporation and its affiliates have failed to
pursue a tender offer or other acquisition permitted under the Restructuring
Agreements. In addition, Continuing Stockholders have been granted
registration rights.
 
  In addition to the above restrictions, the Restructuring Agreements
generally provide that Bayer Corporation and the Continuing Stockholders may
not transfer any of their shares until May 15, 1999. However, Bayer
Corporation may transfer its shares in connection with certain registration
rights granted to Bayer Corporation under the Restructuring Agreements or to a
Permitted Assignee. The Continuing Stockholders may transfer their shares as
provided in the preceding paragraph. A "Permitted Assignee" is (a) a successor
to all or substantially all the business and assets of Bayer or a majority-
owned subsidiary of Bayer Corporation who agrees to be bound by the
Restructuring Agreements, (b) with respect to certain preemptive rights,
rights of first refusal and rights of first offer, a single purchaser who,
immediately after the purchase and for 60 days thereafter, owns at least 10%
of the shares then owned by Bayer Corporation and who agrees to be bound by
the Standstill and (c) with respect to certain registration rights, any person
referred to in (a) above and up to three non-affiliated purchasers who,
immediately after the respective purchases and for 60 days thereafter, own in
the aggregate at least 20% of the shares then owned by Bayer Corporation and
who agree to be bound by the Standstill.
 
  If Bayer Corporation sells any of its shares in the Company to any
unaffiliated third party, then the following of Bayer Corporation's rights
under the Restructuring Agreements terminate: the right to consent to certain
transactions of the Company; the right to purchase additional shares on
Company issuances of equity securities; the right to acquire shares to
maintain an ownership percentage of more than 21% of outstanding shares over
certain 10% holders; the right to acquire from the Company or the Family
Stockholders under certain circumstances after the Standstill Period, shares
for a controlling interest in the Company; and rights of first refusal with
regard to share transfers by Continuing Stockholders. However, certain of
those rights (i.e., rights to purchase additional shares on Company issuances
of equity securities and rights of first refusal) may be transferred to a
single purchaser who owns at least 10% of the Company's shares then owned by
Bayer Corporation and who agrees to be bound by the Standstill obligations.
 
  Mr. Sperber and Mr. Bergman may not transfer any of their shares to Bayer
Corporation except in certain open market transactions and except to the
extent that Bayer Corporation first offered to purchase such shares from the
Family Stockholders and the Family Stockholders did not sell such shares.
 
  The Company may not transfer any of its shares to Bayer Corporation, except
to the extent that Bayer Corporation is entitled to purchase shares under the
Restructuring Agreements and those shares are not purchased in the open market
or from Family Stockholders.
 
  Rights of Inclusion and First Refusal. The Restructuring Agreements provide
that, if at any time prior to the Voting Trust Termination Date, any Family
Stockholder or Family Group member (an "Offeree") receives an offer from a
third party to purchase some or all of the Offeree's shares of Common Stock,
the Offeree wishes to sell the shares (other than in a transaction described
in clauses (a) through (i) of the first paragraph of "--Restrictions on
Transfer" above) and Mr. Sperber, as Voting Trustee, consents to the
transaction, the Company or its designee shall have the right of first refusal
to purchase those shares on the same terms as in the third party offer.
 
                                      67
<PAGE>
 
  Under the Restructuring Agreements, if the Company fails to exercise its
right of first refusal and Bayer Corporation has not sold shares other than to
a Permitted Assignee, such right will be deemed assigned to Bayer Corporation,
provided that (a) the stockholdings of Bayer Corporation may not as a result
of its exercising such right exceed the New Percentage and (b) if as a result
of its exercising such right, Bayer Corporation would own a majority of the
shares of Common Stock. Bayer Corporation will exercise such right at a price
per share equal to the greater of (I) the price contained in the third party
offer and (II) the price determined by an investment banking firm, who will
take into consideration, among other things, that control of the Company will
pass at that time to Bayer Corporation.
 
  In addition, if, prior to the end of the Standstill or the time that Bayer
Corporation sells shares other than to a Permitted Assignee, the Company is
not entitled to exercise the right of first refusal described above and a
Continuing Stockholder is permitted under the Restructuring Agreements, and in
good faith wishes, to sell shares of Common Stock to a third party (other than
sales under Rule 144 under the Securities Act and sales under clauses (b), (i)
and (j) of the first paragraph of "--Restrictions on Transfer" above), Bayer
Corporation shall have the right of first offer to purchase those shares of
Common Stock on the same terms as the Continuing Stockholder wishes to sell
the shares of Common Stock.
 
  The Restructuring Agreements provide that if at any time prior to the
earlier of the second anniversary of the Qualified Public Offering Date and
May 15, 2001, Bayer Corporation is permitted under the Restructuring
Agreements, and in good faith wishes, to sell shares of Common Stock to a
third party, the Company and the Continuing Stockholders shall have the right
of first offer to purchase those shares of Common Stock on the same terms as
the Bayer Corporation wishes to sell the shares of Common Stock.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
  As of September 5, 1995, the Company entered into the Senior Credit
Agreement with a group of lenders. The Chase Manhattan Bank (formerly Chemical
Bank) acts as credit agent thereunder. The Senior Credit Agreement, as
amended, provides a term loan facility of $250.0 million and a revolving
credit facility of $100.0 million, each maturing on December 31, 2001. As of
September 27, 1997, the Company had pre-paid $120 million of the term loan
portion of the Senior Credit Agreement and had permanently reduced the
lenders' commitments with respect thereto and had outstandings under the
revolving credit facility of approximately $26.0 million.
 
  The Company's borrowing can be based, at the option of the Company, on a
spread above LIBOR or an alternate base rate ("ABR"). The interest rate spread
applicable to term loan and revolving credit borrowings fluctuates based on
leverage. The spread, in the case of LIBOR loans, can range from 0.75% to
2.50% and, in the case of ABR loans, from 0% to 1.50%. The ABR is based on a
per annum rate which is the greater of (i) the prime rate of the Credit Agent
(as defined herein), (ii) the secondary market rate for three-month
certificates of deposit as published in Federal Reserve Statistical Release H-
15 (519), plus 1%, and (iii) the Federal Funds rate, plus one-half of 1%. A
commitment fee ranging from 0.25% to 0.50% per annum of the unused daily
amount of the total commitment is payable quarterly.
 
  The term loan facility may be prepaid at any time by the Company. Such
facility is subject to quarterly amortization payments, beginning on September
30, 1998. Annual amortization payments will total $13.7 million, $34.2
million, $41.0 million, and $41.1 million in total between the years 1998
through 2001, respectively. In addition to scheduled amortization, the term
loan facility is subject to mandatory prepayment, without penalty or premium,
to the extent of (a) 75% of excess cash flow for any fiscal year, (b) a
specified percentage, based on leverage, from net proceeds derived from an
equity issuance, (c) 100% of net proceeds from a permitted debt issuance, and
(d) 100% of net proceeds from an asset sale in excess of $1.0 million, all as
more fully set forth in the Senior Credit Agreement.
 
  The Senior Credit Agreement contains a number of affirmative covenants,
including those relating to existence; business and properties; insurance;
taxes; recordkeeping and financial reporting; and notice of certain events, as
well as negative covenants, including: limitations on indebtedness; liens;
sale and lease-back transactions; investments, loans and advances; mergers,
consolidations and sales of assets; dividends and distributions; payment of
dividends by subsidiaries; capital expenditures; transactions with affiliates;
and changes in line of business. The Company is required to maintain specified
financial ratios with respect to leverage, senior debt, fixed charge coverage
and working capital and a minimum net worth.
 
  The Senior Credit Agreement contains customary events of default, including
covenant default, breach of representation and warranty, failure to pay
principal or interest or fees when due, cross-default to other indebtedness,
bankruptcy default, ERISA default, the occurrence of a change in control, the
guarantee agreement or any security document (as defined therein) ceasing to
be in full force and effect and any interest created by a security document
ceasing to be enforceable or ceasing to have the effect and priority purported
to be created thereby.
 
  Borrowings under the Senior Credit Agreement are secured on a senior basis
by mortgages on real property, liens on inventory and receivables and a pledge
of subsidiary stock, which represents substantially all of the Company's
assets. The Company's obligations under the Senior Credit Agreement are
jointly and severally guaranteed on a senior secured basis by the Company's
domestic subsidiaries.
 
  Societe Generale, an affiliate of Societe Generale Securities Corporation,
was the lender under the Senior Subordinated Loan Agreement, dated as of
December 20, 1996, as amended (the "Senior Subordinated Loan Agreement"). All
borrowings under the Senior Subordinated Loan Agreement (the "Senior
Subordinated Loan") were repaid from the proceeds of the Initial Offering. See
"Use of Proceeds."

                              THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
  The Old Notes were originally sold by the Company to the Initial Purchaser
pursuant to the Purchase Agreement. The Initial Purchaser subsequently resold
the Old Notes to qualified institutional buyers in reliance on Rule 144A under
the Securities Act and to a limited number of accredited investors (as defined
in Rule 501(A)(1), (2), (3) or (7) under the Securities Act). As a condition
to the Purchase Agreement, the Company entered into the Registration Rights
Agreement with the Initial Purchaser pursuant to which the Company agreed, for
the benefit of the holders of the Old Notes, at the Company's cost, to (i)
file the Exchange Offer Registration Statement within 45 days after the date
of the original issue of the Old Notes with the Commission with respect to the
Exchange Offer for the New Notes, (ii) use their reasonable best efforts to
cause the Exchange Offer Registration Statement to be declared effective under
the Securities Act within the earlier of (a) 90 days after the Issue Date or
(b) 30 days after the consummation of the initial public offering of the
Company's Common Stock and (iii) unless the Exchange Offer would not be
permitted by applicable law or Commission policy, commence the Exchange Offer
and use their reasonable best efforts to issue as soon as practicable, but in
any event prior to 150 days after the date of the original issue of the Old
Notes, New Notes in exchange for all Old Notes tendered prior thereto in the
Exchange Offer. Upon the Exchange Offer Registration Statement being declared
effective, the Company will offer the New Notes in exchange for surrender of
the Old Notes. The Company will keep the Exchange Offer open for not less than
30 business days (or longer if required by applicable law) after the date on
which notice of the Exchange Offer is mailed to the holders of the Old Notes.
For each Old Note surrendered to the Company pursuant to the Exchange Offer,
the holder of such Old Note will receive a New Note having a principal amount
equal to that of the surrendered Old Note. Each New Note will bear interest
from the last Interest Payment Date. Such interest will be paid with the first
interest payment on the New Notes. Interest on the Old Notes accepted for
exchange will cease to accrue upon issuance of the New Notes. If (i) any
change in law or applicable interpretations of the staff of the Commission
does not permit the Company to effect the Exchange Offer as contemplated
hereby or (ii) the Initial Purchaser, as a holder of Notes, (A) is not
eligible to participate in the Exchange Offer or (B) participates in the
Exchange Offer and does not receive freely transferable Exchange Notes in
exchange for tendered Notes, the Company will file with the Commission and use
commercially reasonable efforts to cause to be declared effective on or prior
to the latter of (x) 120 days after the date of issuance of the Old Notes (the
"Issue Date") or (y) 45 days after the publication of the change in law or
interpretation, a registration statement on an appropriate form under the
Securities Act relating to the offer and sale of the Notes by the holders
thereof, from time to time, in accordance with such registration statement and
Rule 415 under the Securities Act (the "Shelf Registration Statement").
 
  The Company will use commercially reasonable efforts to have the Exchange
Offer Registration Statement or, if applicable, a Shelf Registration Statement
(each a "Registration Statement") declared effective by the Commission as
promptly as practicable after the filing thereof. Unless the Exchange Offer
would not be permitted by a policy of the Commission, the Company will
commence the Exchange Offer and will use its reasonable best efforts to
consummate the Exchange Offer as promptly as practicable, but in any event on
or prior to 150 days after the Issue Date. If applicable, the Company will use
commercially reasonable best efforts to keep the Shelf Registration Statement
effective for the earlier of three years from the Issue Date or such shorter
period that will terminate when all the Notes covered by the Shelf
Registration Statement have been sold, subject to certain exceptions,
including suspending the effectiveness thereof as required by law or for
certain valid business reasons.
 
  In the event (to the extent applicable) that (i) (A) the Exchange Offer
Registration Statement is not filed on or prior to the 45th day following the
Issue Date, (B) the Exchange Offer Registration Statement is not declared
effective within the earlier of (x) 90 days after the Issue Date or (y) 30
days after the consummation of the initial public offering of the Company's
Common Stock or (C) the Exchange Offer is not consummated on or prior to the
150th day following the Issue Date or (ii) the Shelf Registration Statement is
not declared effective on or prior to the later of (x) the 120th day after the
Issue Date and (y) the 45th day after the publication of the
 
                                      70
<PAGE>
 
change in law or interpretation referred to in the second preceding paragraph,
the interest rate borne by the Notes shall be increased by one-half of one
percent per annum following, in the case of clause (i)(A) such 45-day period,
in the case of clauses (i)(B) such 90- or 30-day period, as the case may be,
or in the case of clause (i)(C), such 150-day period, or, in the case of
clause (ii), such 45- or 120-day period, as applicable. The aggregate amount
of such increase from the original interest rate pursuant to these provisions
will in no event exceed one-half of one percent per annum. Such increase will
cease to be effective on the date of filing of the Exchange Offer Registration
Statement, effectiveness of the Exchange Offer Registration Statement,
consummation of the Exchange Offer or the effectiveness of a Shelf
Registration Statement, as the case may be.
 
  Any amounts of additional interest due pursuant to the preceding paragraph
will be payable in cash, on the same original interest payment dates as the
Notes. The amount of additional interest will be determined by multiplying the
applicable additional interest rate by the principal amount of the affected
Notes of such holders, multiplied by a fraction, the numerator of which is the
number of days such additional interest rate was applicable during such
period, and the denominator of which is 360.
 
  The Registration Rights Agreement provides that the Company (i) shall cause
the Exchange Offer Registration Statement to remain continuously effective for
a period of at least 20 Business Days (or longer if required by applicable
law) from its effective date, and shall supplement or amend the Prospectus to
the extent necessary to permit the Prospectus (as supplemented or amended) to
be delivered by broker-dealers in connection with any resale of any such New
Notes and (ii) shall pay all expenses incident to the Exchange Offer and will
indemnify certain holders of the Notes (including any broker-dealer) against
certain liabilities, including liabilities under the Securities Act. A broker-
dealer that delivers such a prospectus to purchasers in connection with such
resales will be subject to certain of the civil liability provisions under the
Securities Act, and will be bound by the provisions of the Registration Rights
Agreement (including certain indemnification rights and obligations).
 
  Each holder of the Notes that wishes to exchange such Notes for New Notes in
the Exchange Offer will be required to make certain representations, including
representations that (i) any New Notes to be received by it will be acquired
in the ordinary course of its business, (ii) it has no arrangement with any
person to participate in the distribution of the New Notes and (iii) it is not
an "affiliate," as defined in Rule 405 of the Securities Act, of the Company
or if it is an affiliate, it will comply with the registration and prospectus
delivery requirements of the Securities Act to the extent applicable.
 
  Under existing interpretations of the staff of the Commission contained in
several no-action letters to third parties, the New Notes will in general be
freely tradeable after the Exchange Offer without further registration under
the Securities Act. However, any purchaser of Old Notes who is an "affiliate"
of the Company or who intends to participate in the Exchange Offer for the
purpose of distributing the New Notes (i) will not be able to rely on the
interpretation of the staff of the Commission, (ii) will not be able to tender
its Old Notes in the Exchange Offer and (iii) must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any sale or transfer of the Old Notes, unless such sale or
transfer is made pursuant to an exemption from such requirements.
 
  As contemplated by these no-action letters and the Registration Rights
Agreement, each holder accepting New Notes in the Exchange Offer is required
to represent to the Company in the Letter of Transmittal that (i) the New
Notes are to be acquired by the holder or the person receiving such New Notes,
whether or not such person is the holder, in the ordinary course of business,
(ii) the holder or any such other person (other than a broker-dealer referred
to in the next sentence) is not engaging, and does not intend to engage, in a
distribution of the New Notes, (iii) the holder or any such other person has
no arrangement or understanding with any person to participate in the
distribution of the New Notes, (iv) neither the holder nor any such other
person is an "affiliate" of the Company within the meaning of Rule 405 under
the Securities Act, and (v) the holder or any such other person acknowledges
that if such holder or any other person participates in the Exchange Offer for
the purpose of distributing the New Notes it must comply with the registration
and prospectus delivery requirements of the
 
                                      71
<PAGE>
 
Securities Act in connection with any resale of the New Notes and cannot rely
on those no-action letters. Each Participating Broker-Dealer that receives New
Notes for its own account in exchange for Old Notes, where such Old Notes were
acquired by such Participating Broker-Dealer as a result of market-making
activities or other trading activities, must acknowledge that it will deliver
a prospectus in connection with any resale of such New Notes. See "Plan of
Distribution."
 
  If a holder is not a broker-dealer, it will be required to represent that it
is not engaged in, and does not intend to engage in, the distribution of the
New Notes. If a holder is a broker-dealer that will receive New Notes for its
own account in exchange for Notes that were acquired as a result of market
making activities or other trading activities, it will be required to
acknowledge that it will deliver a prospectus in connection with any resale of
such New Notes.
 
  Holders of the Notes will be required to make certain representations to the
Company in order to participate in the Exchange Offer, and will be required to
deliver information to be used in connection with the Shelf Registration
Statement in order to have their Notes included in the Shelf Registration
Statement. A holder who sells Notes pursuant to the Shelf Registration
Statement generally will be required to be named as a selling security holder
in the related prospectus and to deliver a prospectus to purchasers, will be
subject to certain of the civil liability provisions under the Securities Act
in connection with such sales and will be bound by the provisions of the
Registration Rights Agreement which are applicable to such a holder (including
certain indemnification obligations).
 
  A holder whose Notes are included in a Registration Statement will be
required to agree not to effect any public sale or distribution of the issue
being registered or a similar security of the Company or any securities
convertible into or exchangeable or exercisable for such securities, including
a sale pursuant to Rule 144 under the Securities Act, during the 14 days prior
to, and during the 90-day period beginning on, the effective date of such
Registration Statement (except as part of such registration), if and to the
extent requested by the Company in the case of a non-underwritten public
offering or if and to the extent requested by the managing Underwriter or
Underwriters in the case of an underwritten public offering.
 
  Unless the Company is then subject to Section 13 or 15(d) of the Exchange
Act, the Company will continue to provide to holders of the Notes and to
prospective purchasers of the Notes, for so long as the Notes are outstanding,
the information required by Rule 144A under the Securities Act ("Rule 144A"),
as such Rule may be amended, or any similar rule or regulation adopted by the
Commission. The Company will provide a copy of the Registration Rights
Agreement to prospective purchasers of Notes identified to the Company by the
Initial Purchaser upon request.
 
  The foregoing description of the Registration Rights Agreement is a summary
only, does not purport to be complete and is qualified in its entirety by
reference to all provisions of the Registration Rights Agreement.
 
TERMS OF THE EXCHANGE OFFER
 
  Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all Old
Notes validly tendered and not withdrawn prior to 5:00 p.m., New York City
time, on the Expiration Date. The Company will issue $1,000 principal amount
of New Notes in exchange for each $1,000 principal amount of Old Notes
accepted in the Exchange Offer. Holders may tender some or all of their Old
Notes pursuant to the Exchange Offer. However, Old Notes may be tendered only
in integral multiples of $1,000.
 
  The form and terms of the New Notes are the same as the form and terms of
the Old Notes in all material respects except that (i) the New Notes bear a
different CUSIP number from the Old Notes and (ii) the New Notes have been
registered under the Securities Act and hence will not bear legends
restricting the transfer thereof. The New Notes will evidence the same debt as
the Old Notes and will be entitled to the benefits of the Indenture.

  As of the date of this Prospectus, $100,000,000 aggregate principal amount
of Old Notes were outstanding. The Company has fixed the close of business on
     , 1998 as the record date for the Exchange Offer for the purposes of
determining the persons to whom this Prospectus and the Letter of Transmittal
will be mailed initially.
 
  Holders of Old Notes do not have any appraisal or dissenters' rights under
the General Corporation Law of Delaware or the Indenture in connection with
the Exchange Offer. The Company intends to conduct the Exchange Offer in
accordance with the applicable requirements of the Exchange Act and the rules
and regulations of the Commission thereunder.
 
  The Company shall be deemed to have accepted validly tendered Old Notes
when, as and if the Company has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
for the purpose of receiving the New Notes from the Company.
 
  If any tendered Old Notes are not accepted for exchange because of an
invalid tender, the occurrence of certain other events set forth herein or
otherwise, the certificates for any such unaccepted Old Notes will be
returned, without expense, to the tendering holder thereof as promptly as
practicable after the Expiration Date.
 
  Holders who tender Old Notes in the Exchange Offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the
Letter of Transmittal, transfer taxes with respect to the exchange of Old
Notes pursuant to the Exchange Offer. The Company will pay all charges and
expenses, other than transfer taxes in certain circumstances, in connection
with the Exchange Offer. See "--Fees and Expenses."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
  The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
 , 1998, unless the Company in its sole discretion extends the Exchange Offer,
in which case the term "Expiration Date" shall mean the latest date and time
to which the Exchange Offer is extended.
 
  In order to extend the Exchange Offer, the Company will issue a notice of
such extension by press release or other public announcement prior to 9:00
a.m., New York City time, on the next business day following the previously
scheduled Expiration Date.
 
  The Company expressly reserves the right, in its sole discretion, prior to
the Expiration Date (i) to delay accepting any Old Notes, to extend the
Exchange Offer or to terminate the Exchange Offer if any of the conditions set
forth below under "Conditions" shall not have been satisfied, by giving oral
or written notice of such delay, extension or termination to the Exchange
Agent or (ii) to amend the terms of the Exchange Offer in any manner. Any such
delay in acceptance, extension, termination or amendment will be followed as
promptly as practicable by oral or written notice thereof to the registered
holders.
 
PROCEDURES FOR TENDERING
 
  Only a holder of Old Notes may tender such Old Notes in the Exchange Offer.
To tender in the Exchange Offer, a holder must complete, sign and date the
Letter of Transmittal, or a facsimile thereof, have the signatures thereon
guaranteed if required by the Letter of Transmittal, and mail or otherwise
deliver such Letter of Transmittal or such facsimile, together with the Old
Notes and any other required documents, to the Exchange Agent prior to 5:00
p.m., New York City time, on the Expiration Date. To be tendered effectively,
the Old Notes, Letter of Transmittal or an Agent's Message in connection with
a book-entry transfer and other required documents must be completed and
received by the Exchange Agent at the address set forth below under "Exchange
Agent" prior to 5:00 p.m., New York City time, on the Expiration Date.
Delivery of the Old Notes may be made by book-entry transfer in accordance
with the procedures described below. Confirmation of such book-entry transfer
must be received by the Exchange Agent prior to the Expiration Date.
 
  The term "Agent's Message" means a message transmitted by a book-entry
transfer facility to, and received by, the Exchange Agent forming a part of a
confirmation of a book-entry transfer, which states that
 
                                      73
<PAGE>
 
such book-entry transfer facility has received an express acknowledgment from
the participant in such book-entry transfer facility tendering the Notes that
such participant has received and agrees to be bound by the terms of the
Letter of Transmittal and that the Company may enforce such agreement against
such participant.
 
  By executing the Letter of Transmittal, each holder will make the
representations set forth above in the seventh paragraph under the heading "--
Purpose and Effect of the Exchange Offer."
 
  Each Participating Broker-Dealer that receives New Notes for its own account
in exchange for Old Notes, where such Old Notes were acquired by such
Participating Broker-Dealer as a result of market-making activities, or other
trading activities, must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes. See "Plan of Distribution."
 
  The tender by a holder and the acceptance thereof by the Company will
constitute agreement between such holder and the Company in accordance with
the terms and subject to the conditions set forth herein and in the Letter of
Transmittal.
 
  THE METHOD OF DELIVERY OF OLD NOTES AND THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND SOLE
RISK OF THE HOLDER. AS AN ALTERNATIVE TO DELIVERY BY MAIL, HOLDERS MAY WISH TO
CONSIDER OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE
EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO THE
COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL
BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS.
 
  Any beneficial owner whose Old Notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to
tender should contact the registered holder promptly and instruct such
registered holder to tender on such beneficial owner's behalf.
 
  Signatures on a Letter of Transmittal or a notice of withdrawal, as the case
may be, must be guaranteed by an Eligible Institution (as defined) unless the
Old Notes tendered pursuant thereto are tendered (i) by a registered holder
who has not completed the box entitled "Special Issuance Instructions" or
"Special Delivery Instructions" on the Letter of Transmittal or (ii) for the
account of an Eligible Institution. In the event that signatures on a Letter
of Transmittal or a notice of withdrawal, as the case may be, are required to
be guaranteed, such guarantee must be by a member firm of the Medallion System
(an "Eligible Institution").
 
  If the Letter of Transmittal is signed by a person other than the registered
holder of any Old Notes listed therein, such Old Notes must be endorsed or
accompanied by a properly completed bond power, signed by such registered
holder as such registered holder's name appears on such Old Notes with the
signature thereon guaranteed by an Eligible Institution.
 
  If the Letter of Transmittal or any Old Notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and evidence satisfactory to the
Company of their authority to so act must be submitted with the Letter of
Transmittal.
 
  The Company understands that the Exchange Agent will make a request promptly
after the date of this Prospectus to establish accounts with respect to the
Old Notes at DTC for the purpose of facilitating the Exchange Offer, and
subject to the establishment thereof, any financial institution that is a
participant in DTC's system may make book-entry delivery of Old Notes by
causing DTC to transfer such Old Notes into the Exchange Agent's account with
respect to the Old Notes in accordance with DTC's procedures for such
transfer. Although delivery of the Old Notes may be effected through book-
entry transfer into the Exchange Agent's account at DTC, an appropriate Letter
of Transmittal properly completed and duly executed with any required
 
                                      74
<PAGE>
 
signature guarantee and all other required documents must in each case be
transmitted to and received or confirmed by the Exchange Agent at its address
set forth below on or prior to the Expiration Date, or, if the guaranteed
delivery procedures described below are complied with, within the time period
provided under such procedures. Delivery of documents to DTC does not
constitute delivery to the Exchange Agent.
 
  All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Old Notes and withdrawal of tendered Old
Notes will be determined by the Company in its sole discretion, which
determination will be final and binding. The Company reserves the absolute
right to reject any and all Old Notes not properly tendered or any Old Notes
the Company's acceptance of which would, in the opinion of counsel for the
Company, be unlawful. The Company also reserves the right in its sole
discretion to waive any defects, irregularities or conditions of tender as to
particular Old Notes. The Company's interpretation of the terms and conditions
of the Exchange Offer (including the instructions in the Letter of
Transmittal) will be final and binding on all parties. Unless waived, any
defects or irregularities in connection with tenders of Old Notes must be
cured within such time as the Company shall determine. Although the Company
intends to notify holders of defects or irregularities with respect to tenders
of Old Notes, neither the Company, the Exchange Agent nor any other person
shall incur any liability for failure to give notification. Tenders of Old
Notes will not be deemed to have been made until such defects or
irregularities have been cured or waived. Any Old Notes received by the
Exchange Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering holders, unless otherwise provided in the Letter of
Transmittal, as soon as practicable following the Expiration Date.
 
GUARANTEED DELIVERY PROCEDURES
 
  Holders who wish to tender their Old Notes and (i) whose Old Notes are not
immediately available, (ii) who cannot deliver their Old Notes, the Letter of
Transmittal or any other required documents to the Exchange Agent or (iii) who
cannot complete the procedures for book-entry transfer, prior to the
Expiration Date, may effect a tender if:
 
    (a) the tender is made through an Eligible Institution;
 
    (b) prior to the Expiration Date, the Exchange Agent receives from such
  Eligible Institution a properly completed and duly executed Notice of
  Guaranteed Delivery (by facsimile transmission, mail or hand delivery)
  setting forth the name and address of the holder, the certificate number(s)
  of such Old Notes and the principal amount of Old Notes tendered, stating
  that the tender is being made thereby and guaranteeing that, within five
  New York Stock Exchange trading days after the Expiration Date, the Letter
  of Transmittal (or facsimile thereof) together with the certificate(s)
  representing the Old Notes (or a confirmation of book-entry transfer of
  such Notes into the Exchange Agent's account at DTC), and any other
  documents required by the Letter of Transmittal will be deposited by the
  Eligible Institution with the Exchange Agent; and
 
    (c) such properly completed and executed Letter of Transmittal (or
  facsimile thereof), as well as the certificate(s) representing all tendered
  Old Notes in proper form for transfer (or a confirmation of book-entry
  transfer of such Old Notes into the Exchange Agent's account of DTC), and
  all other documents required by the Letter of Transmittal are received by
  the Exchange Agent upon five New York Stock Exchange trading days after the
  Expiration Date.
 
  Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Old Notes according to the guaranteed
delivery procedures set forth above.
 
WITHDRAWAL OF TENDERS
 
  Except as otherwise provided herein, tenders of Old Notes may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the Expiration Date.
 
                                      75
<PAGE>
 
  To withdraw a tender of Old Notes in the Exchange Offer, a telegram, telex,
letter or facsimile transmission notice of withdrawal must be received by the
Exchange Agent at its address set forth herein prior to 5:00 p.m., New York
City time, on the Expiration Date. Any such notice of withdrawal must: (i)
specify the name of the person having deposited the Old Notes to be withdrawn
(the "Depositor"); (ii) identify the Old Notes to be withdrawn (including the
certificate number(s) and principal amount of such Old Notes, or, in the case
of Old Notes transferred by book-entry transfer, the name and number of the
account at the DTC to be credited); (iii) be signed by the holder in the same
manner as the original signature on the Letter of Transmittal by which such
Old Notes were tendered (including any required signature guarantees) or be
accompanied by documents of transfer sufficient to have the Trustee with
respect to the Old Notes register the transfer of such Old Notes into the name
of the person withdrawing the tender; and (iv) specify the name in which any
such Old Notes are to be registered, if different from that of the Depositor.
All questions as to the validity, form and eligibility (including time of
receipt) of such notices will be determined by the Company, whose
determination shall be final and binding on all parties. Any Old Notes so
withdrawn will be deemed not to have been validly tendered for purposes of the
Exchange Offer and no New Notes will be issued with respect thereto unless the
Old Notes so withdrawn are validly retendered. Any Old Notes which have been
tendered but which are not accepted for exchange will be returned to the
holder thereof without cost to such holder as soon as practicable after
withdrawal, rejection of tender or termination of the Exchange Offer. Properly
withdrawn Old Notes may be retendered by following one of the procedures
described above under "--Procedures for Tendering" at any time prior to the
Expiration Date.
 
CONDITIONS
 
  Notwithstanding any other term of the Exchange Offer, the Company shall not
be required to accept for exchange, or exchange New Notes for, any Old Notes,
and may terminate or amend the Exchange Offer as provided herein prior to the
Expiration Date, if:
 
    (a) any action or proceeding is instituted or threatened in any court or
  by or before any governmental agency with respect to the Exchange Offer
  which, in the reasonable judgment of the Company, might materially impair
  the ability of the Company to proceed with the Exchange Offer or any
  material adverse development has occurred in any existing action or
  proceeding with respect to the Company or any of its subsidiaries; or
 
    (b) any law, statute, rule, regulation or interpretation by the staff of
  the Commission is proposed, adopted or enacted, which, in the reasonable
  judgment of the Company, might materially impair the ability of the Company
  to proceed with the Exchange Offer or materially impair the contemplated
  benefits of the Exchange Offer to the Company; or
 
    (c) any governmental approval has not been obtained, which approval the
  Company shall, in its reasonable discretion, deem necessary for the
  consummation of the Exchange Offer as contemplated hereby.
 
  If the Company determines in its reasonable discretion that any of the above
conditions are not satisfied, the Company may (i) refuse to accept any Old
Notes and return all tendered Old Notes to the tendering holders, (ii) extend
the Exchange Offer and retain all Old Notes tendered prior to the expiration
of the Exchange Offer, subject, however, to the rights of holders to withdraw
such Old Notes (see "--Withdrawal of Tenders") or (iii) waive such unsatisfied
conditions with respect to the Exchange Offer and accept all properly tendered
Old Notes which have not been withdrawn.

  DELIVERY TO AN ADDRESS OTHER THAN SET FORTH ABOVE WILL NOT CONSTITUTE A
VALID DELIVERY.
 
FEES AND EXPENSES
 
  The expenses of soliciting tenders will be borne by the Company. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telegraph, telecopy, telephone or in person by officers and
regular employees of the Company and its affiliates.
 
  The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers, or others
soliciting acceptances of the Exchange Offer. The Company, however, will pay
the Exchange Agent reasonable and customary fees for its services and will
reimburse it for its reasonable out-of-pocket expenses in connection
therewith.
 
  The cash expenses to be incurred in connection with the Exchange Offer will
be paid by the Company. Such expenses include fees and expenses of the
Exchange Agent and Trustee, accounting and legal fees and printing costs,
among others.
 
ACCOUNTING TREATMENT
 
  The New Notes will be recorded at the same carrying value as the Old Notes,
which is face value, as reflected in the Company's accounting records on the
date of exchange. Accordingly, no gain or loss for accounting purposes will be
recognized by the Company. The expenses of the Exchange Offer will be expensed
over the term of the New Notes.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
  The Old Notes that are not exchanged for New Notes pursuant to the Exchange
Offer will remain restricted securities. Accordingly, such Old Notes may be
resold only (i) to the Company (upon redemption thereof or otherwise), (ii) so
long as the Old Notes are eligible for resale pursuant to Rule 144A, to a
person inside the United States whom the seller reasonable believes is a
qualified institutional buyer within the meaning of Rule 144A under the
Securities Act in a transaction meeting the requirements of Rule 144A, (iii)
in accordance with Rule 144 under the Securities Act, or pursuant to another
exemption from the registration requirements of the Securities Act (and based
upon an opinion of counsel reasonably acceptable to the Company), (iv) outside
the United States to a foreign person in a transaction meeting the
requirements of Rule 904 under the Securities Act, or (v) pursuant to an
effective registration under the Securities Act, in each case in accordance
with any applicable securities laws of any state of the United States.

RESALE OF THE NEW NOTES
 
  With respect to resales of New Notes, based on interpretations by the staff
of the Commission set forth in no-action letters issued to third parties, the
Company believes that a holder or other person who receives New Notes, whether
or not such person is the holder (other than a person that is an "affiliate"
of the Company within the meaning of Rule 405 under the Securities Act) who
receives New Notes in exchange for Old Notes in the ordinary course of
business and who is not participating, does not intend to participate, and has
no arrangement or understanding with any person to participate, in the
distribution of the New Notes, will be allowed to resell the New Notes to the
public without further registration under the Securities Act and without
delivering to the purchasers of the New Notes a prospectus that satisfies the
requirements of Section 10 of the Securities Act. However, if any holder
acquires New Notes in the Exchange Offer for the purpose of distributing or
participating in a distribution of the New Notes, such holder cannot rely on
the position of the staff of the Commission enunciated in such no-action
letters or any similar interpretative letters, and must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction, unless an exemption from registration
is otherwise available. Further, each Participating Broker-Dealer that
receives New Notes for its own account in exchange for Old Notes, where such
Old Notes were acquired by such Participating Broker-Dealer as a result of
market-making activities or other trading activities, must acknowledge that it
will deliver a prospectus in connection with any resale of such New Notes.
 
  As contemplated by these no-action letters and the Registration Rights
Agreement, each holder accepting the Exchange Offer is required to represent
to the Company in the Letter of Transmittal that (i) the New Notes are to be
acquired by the holder or the person receiving such New Notes, whether or not
such person is the holder, in the ordinary course of business, (ii) the holder
or any such other person (other than a broker-dealer referred to in the next
sentence) is not engaging, and does not intend to engage, in the distribution
of the New Notes, (iii) the holder or any such other person has no arrangement
or understanding with any person to participate in the distribution of the New
Notes, (iv) neither the holder nor any such other person is an "affiliate" of
the Company within the meaning of Rule 405 under the Securities Act, and (v)
the holder or any such other person acknowledges that if such holder or other
person participates in the Exchange Offer for the purpose of distributing the
New Notes it must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any resale of the New
Notes and cannot rely on those no-action letters. As indicated above, each
Participating Broker-Dealer that receives a New Note for its own account in
exchange for Old Notes must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes. For a description of the
procedures for such resales by Participating Broker-Dealers, see "Plan of
Distribution."

<PAGE>
 
                             DESCRIPTION OF NOTES
 
GENERAL
 
  The New Notes are to be issued under an indenture, dated as of December 24,
1997 (the "Indenture") between the Company, the Guarantors and The Bank of New
York, as Trustee (the "Trustee"), a copy of which is available upon request to
the Company. The form and terms of the New Notes are the same as the form and
terms of the Old Notes (which they replace) except that (i) the New Notes have
been registered under the Securities Act and (ii) the holders of New Notes
will not be entitled to certain rights under the Registration Rights
Agreement, including the provisions providing for an increase in the interest
rate of the Old Notes in certain circumstances relating to the timing of the
Exchange Offer, which rights will terminate when the Exchange Offer is
consummated. The following summary of certain provisions of the Indenture and
the Notes does not purport to be complete and is subject to, and is qualified
in its entirety by reference to, all the provisions of the Indenture
(including the definitions of certain terms therein and those terms made a
part thereof by the Trust Indenture Act of 1939, as amended (the "Trust
Indenture Act")) and the Notes. Capitalized terms used herein and not
otherwise defined have the meanings set forth in "--Certain Definitions."
 
  Under certain circumstances, the Company will be able to designate current
or future Subsidiaries as Unrestricted Subsidiaries. Unrestricted Subsidiaries
will not be subject to the restrictive covenants set forth in the Indenture.
As of the date of the Indenture, all of the Company's Subsidiaries other than
Schein Pharmaceutical (Netherlands) B.V., Schein Pharmaceutical (Bermuda) Ltd.
and Schein Farmaceutica de Peru will be Restricted Subsidiaries.
 
TERMS OF THE NOTES
 
  Interest on each New Note will accrue from the last Interest Payment Date on
which interest was paid on the Old Note tendered in exchange therefor. Holders
of Old Notes whose Old Notes are accepted for exchange will be deemed to have
waived the right to receive any payment in respect of interest on the Old
Notes accrued from the last Interest Payment Date to the date of the issuance
of the New Notes. Consequently, holders who exchange their Old Notes for New
Notes will receive the same interest payment on the same Interest Payment Date
that they would have received had they not accepted the Exchange Offer.
Interest on the New Notes is payable quarterly on January 15, April 15, July
15 and December 15 of each year accruing from the last Interest Payment Date
at a rate equal to the Applicable LIBOR Rate.
 
  The "Applicable LIBOR Rate" means, for each quarterly period during which
any Note is outstanding subsequent to the initial quarterly period, 300 basis
points over the rate determined by the Company (notice of such rate to be sent
to the Trustee by the Company on the date of determination thereof) equal to
the average (rounded upwards, if necessary, to the nearest 1/16 of 1%) of the
offered rates for deposits in U.S. dollars for a period of three months, as
set forth on the Reuters Screen LIBO Page as of 11:00 a.m., London time, on
the Interest Rate Determination Date for such quarterly period; provided,
however, that if only one such offered rate appears on the Reuters Screen LIBO
Page, the Applicable LIBOR Rate for such quarterly period will mean such
offered rate. If such rate is not available at 11:00 a.m., London time, on the
Interest Rate Determination Date for such quarterly period, then the
Applicable LIBOR Rate for such quarterly period will mean the arithmetic mean
(rounded upwards, if necessary, to the nearest 1/16 of 1%) of the interest
rates per annum at which deposits in amounts equal to US$1 million are offered
by the Reference Banks to leading banks in the London interbank market for a
period of three months as of 11:00 a.m., London time, on the Interest Rate
Determination Date for such quarterly period. If on any Interest Rate
Determination Date, at least two of the Reference Banks provide such offered
quotations, then the Applicable LIBOR Rate for such quarterly period will be
determined in accordance with the preceding sentence on the basis of the
offered quotations of those Reference Banks providing such quotations;
provided, however, that if fewer than two of the Reference Banks are so
quoting such interest rates as mentioned above, the Applicable LIBOR Rate for
such quarterly period shall be deemed to be the
 
                                      79
<PAGE>
 
applicable LIBOR Rate for the next preceding quarterly period and in the case
of the quarterly period next succeeding the initial quarterly period, the
Applicable LIBOR Rate shall be 8.9375%.
 
  "Interest Rate Determination Date" means, with respect to each quarterly
period, the second London Banking Day prior to the first day of such quarterly
period.
 
  "LIBOR Fraction" means the actual number of days in the quarterly period
divided by 360; provided, however, that the number of days in each quarterly
period shall be calculated by including the first day of such quarterly period
and excluding the last.
 
  "London Banking Day" means any day in which dealings in U.S. dollars are
transacted or, with respect to any future date, are expected to be transacted
in the London interbank market.
 
  "quarterly period" means the period from and including a scheduled payment
date (or December 24, 1997, in the case of the initial quarterly period)
through the day next preceding the following scheduled interest payment date.
 
  "Reference Banks" means each of: Societe Generale, London Branch; The Chase
Manhattan Bank, London Branch; Deutsche Bank, London Branch; and Rabobank
Nederland, London Branch and any such replacement bank thereof as listed on
the Reuters Screen LIBO Page and their respective successors, and if any such
banks are not at the applicable time providing interest rates as contemplated
within the definition of the "Applicable LIBOR Rate," Reference Banks shall
mean the remaining bank or banks so providing such rates. In the event that
less than two of such banks are providing such rates, the Company shall use
reasonable efforts to appoint additional Reference Banks so that there are at
least two such banks providing such rates; provided, however, that such banks
appointed by the Company shall be London offices of leading banks engaged in
the London interbank market.
 
  "Reuters Screen LIBO Page" means the display designated as page "LIBO" on
the Reuter Monitor Money Rates Service (or such other page as may replace the
LIBO page on that service for the purpose of displaying London Interbank
Offered Rates of leading banks).
 
  If the date due for payment of interest on or principal of the Notes or the
date fixed for redemption of any Note shall not be a Business Day (as defined
herein), then payment of interest or principal need not be made on such date,
but may be made on the next succeeding Business Day with the same force and
effect as if made on the date of maturity or the date fixed for redemption,
and no interest shall accrue for the period after such date.
 
OPTIONAL REDEMPTION
 
  The Notes will be redeemable, at the option of the Company, in whole or in
part, at any time, upon not less than 30 nor more than 60 days' prior notice,
at 103.000% of the principal amount thereof, plus accrued and unpaid interest
thereon to, but excluding the date of redemption, and at the following
redemption prices (expressed as a percentage of principal amount), plus
accrued and unpaid interest thereon to, but excluding, the date of redemption,
if redeemed during the 12-month period commencing on January 15 of each year:

  If less than all of the Notes are to be redeemed, the Trustee shall select
the Notes or portions thereof to be redeemed pro rata, by lot or by any other
method the Trustee shall deem fair and reasonable, although no Note of $1,000
in original principal amount will be redeemed in part.

SINKING FUND
 
  The Notes will not be entitled to the benefit of any sinking fund or other
mandatory redemption obligation prior to maturity.
 
GUARANTEES
 
  All of the Company's existing and future Restricted Subsidiaries (referred
to herein as the "Guarantors"), will unconditionally guarantee on a senior
unsecured basis the performance and punctual payment when due, whether at
maturity, by acceleration or otherwise, of all obligations of the Company
under the Indenture and the Notes. Each of the Guarantors has guaranteed the
Company's indebtedness under the Senior Credit Agreement on a senior secured
basis. The Subsidiary Guarantee of each Guarantor will be effectively
subordinated to the prior payment in full of all secured indebtedness of such
Guarantors, including secured indebtedness under the Senior Credit Agreement.
 
  Each Subsidiary Guarantee will be limited to an amount not to exceed the
maximum amount that can, after giving effect to all other contingent and fixed
liabilities of the applicable Guarantor, be guaranteed by such Guarantor,
without rendering such Subsidiary Guarantee voidable under applicable law
relating to fraudulent conveyance or fraudulent transfer or similar laws
affecting the rights of creditors generally. Each Guarantor will agree to pay,
in addition to the amount stated above, any and all costs and expenses
(including reasonable counsel fees and expenses) incurred by the Trustee or
any holder of a Note in enforcing any rights under the Subsidiary Guarantee
with respect to such Guarantor.
 
  Each Subsidiary Guarantee is a continuing guarantee and shall (a) remain in
full force and effect until payment in full of all the Notes, (b) be binding
upon the relevant Guarantor and (c) enure to the benefit of and be enforceable
by the Trustee, the holders of Notes and their successors, transferees and
assigns.
 
RANKING
 
  The indebtedness evidenced by the Notes will be senior unsecured obligations
of the Company, will rank pari passu in right of payment with all existing and
future senior indebtedness of the Company and will rank senior in right of
payment to all existing and future indebtedness of the Company that is, by its
terms, expressly subordinated to the Notes. The Notes will also be effectively
subordinated to all existing and future indebtedness of any Subsidiary of the
Company that is not a Guarantor of the Notes.
 
  Holders of secured indebtedness of the Company, including the lenders under
the Senior Credit Agreement, will have claims with respect to the assets
constituting collateral for such indebtedness that are prior to the claims of
holders of the Notes. In the event of a default on the Notes, or a bankruptcy,
liquidation or reorganization of the Company, such assets will be available to
satisfy obligations with respect to the indebtedness secured thereby before
any payment therefrom could be made on the Notes. To the extent that the value
of such collateral is not sufficient to satisfy the indebtedness secured
thereby, amounts remaining outstanding on such indebtedness would be entitled
to share with the Notes and their claims with respect to any other assets of
the Company. As of September 27, 1997, as adjusted for the Offering, the
Company and its Restricted Subsidiaries would have had secured indebtedness of
approximately $160.6 million outstanding. The obligations of the Company and
the Guarantors under the Senior Credit Agreement are secured by substantially
all of the assets of the Company and the Guarantors. As of September 27, 1997,
as adjusted for the Initial Offering, the Company would have had approximately
$69.8 million of undrawn availability under the Senior Credit Agreement. The
Indenture will permit the Company and its Restricted Subsidiaries to incur
additional Indebtedness, including Secured Indebtedness, subject to certain
limitations.
 
CHANGE OF CONTROL
 
  If a Change of Control shall occur at any time, then each holder of Notes
shall have the right to require that the Company purchase such holder's Notes
in whole or in part in any integral multiple of $1,000, for a cash
 
                                      81
<PAGE>
 
purchase price (the "Change of Control Purchase Price") equal to 101% of the
principal amount of such Notes, plus accrued and unpaid interest, if any, on
such Notes to the date of purchase (the "Change of Control Purchase Date"),
pursuant to the offer described below (the "Change of Control Offer") and the
other procedures set forth in the Indenture.
 
  Within 15 days following any Change of Control, the Company shall notify the
Trustee thereof and give written notice of such Change of Control to each
holder of Notes by first-class mail, postage prepaid, at his address appearing
in the security register, stating, among other things: (i) that a Change of
Control has occurred and that such Holder has the right to require the Company
to purchase each Holder's Notes, in whole or in part, at the Change of Control
Purchase Price; (ii) the Change of Control Purchase Price and the Change of
Control Purchase Date which shall be a Business Day no earlier than 30 days
nor later than 60 days from the date such notice is mailed, or such later date
as is necessary to comply with requirements under the Exchange Act; (iii) that
any Note not tendered for purchase will continue to accrue interest; (iv)
that, unless the Company defaults in the payment of the Change of Control
Purchase Price, any Notes accepted for payment pursuant to the Change of
Control Offer shall cease to accrue interest after the Change of Control
Purchase Date; and (v) certain other procedures that a holder of Notes must
follow to accept a Change of Control Offer or to withdraw such acceptance.
 
  If a Change of Control Offer is made, there can be no assurance that the
Company will have available funds sufficient to pay the Change of Control
Purchase Price for all of the Notes that might be delivered by holders of the
Notes seeking to accept the Change of Control Offer. The Senior Credit
Agreement prohibits the purchase of the Notes by the Company prior to full
repayment of Indebtedness thereunder and, upon a Change of Control, all
amounts outstanding under the Senior Credit Agreement may become due and
payable. There can be no assurance that, in the event of a Change of Control,
the Company will be able to obtain the necessary consents from the lenders
under the Senior Credit Agreement to consummate a Change of Control Offer. The
failure of the Company to make or consummate the Change of Control Offer or
pay the Change of Control Purchase Price when due would result in an Event of
Default.
 
  The existence of a right of the holder of Notes to require the Company to
purchase such holder's Notes upon a Change of Control may deter a third party
from acquiring the Company in a transaction which constitutes a Change of
Control.
 
  The Company will comply with the applicable tender offer rules, including
Rule 14e-1 under the Exchange Act, and any other applicable securities laws or
regulations in connection with a Change of Control Offer.
 
  The Company will not, and will not permit any Subsidiary to, create or
permit to exist or become effective any restriction (other than restrictions
in effect on the Issue Date with respect to Indebtedness outstanding on the
Issue Date and refinancing thereof and customary default provisions) that
would materially impair the ability of the Company to make a Change of Control
Offer to purchase the Notes or, if such Change of Control Offer is made, to
pay for the Notes tendered for purchase.

less principal repayments of term loans and permanent commitment reductions
with respect to revolving loans and letters of credit under the Senior Credit

with respect to Indebtedness of the Company or such Restricted Subsidiary
incurred without violation of the Indenture or with respect to customary
commercial transactions of the Company or such Restricted Subsidiary entered
into in the ordinary course of business; (vii) Indebtedness (including
Capitalized Lease Obligations) incurred by the Company or any Restricted
Subsidiary to finance the purchase, lease or improvement of property (real or
personal) or equipment (whether through the direct purchase of assets or the

amount which, when aggregated with the principal amount of all other
Indebtedness then outstanding and incurred pursuant to this clause (vii), does
not exceed $25.0 million; (viii) Indebtedness incurred by the Company or any
Restricted Subsidiary constituting reimbursement obligations with respect to

such obligations are reimbursed within 30 days following such incurrence; (ix)
Acquired Indebtedness; provided, however, that such Indebtedness is not
incurred in contemplation of such acquisition or merger; and provided, further
that the Company would have been able to incur such Indebtedness at the time
of the incurrence thereof pursuant to clause (a) above, determined on a pro
forma basis as if such transaction had occurred at the beginning of such four-
quarter period and such Indebtedness and the operating results of such merged
or acquired entity had been included for all purposes in such pro forma
calculation as if such entity had been a Restricted Subsidiary at the
beginning of such four-quarter period; (x) obligations in respect of
performance and surety bonds and completion guarantees provided by the Company
or any Restricted Subsidiary in the ordinary course of business; (xi)

however, that (A) the principal amount of such Refinancing Indebtedness shall
not exceed the principal or accreted amount (in the case of any Indebtedness
issued with original issue discount, as such) of Indebtedness so extended,
refinanced, renewed, replaced, substituted or refunded (the "Refinanced
Indebtedness"), (B) the Refinancing Indebtedness shall have a Weighted Average
Life to Maturity of not less than the stated maturity of the Refinanced

Subordinated Indebtedness unless such Indebtedness shall be subordinated to
the Notes to at least the same extent as such Subordinated Indebtedness or
(ii) pursuant to paragraph (a) or (b) if such Indebtedness is subordinate or
junior in ranking in any respect to any Senior Indebtedness unless such
Indebtedness is expressly subordinated in right of payment to such Senior
Indebtedness.
 
  (d) The Company shall not incur any Secured Indebtedness that is not Senior
Indebtedness.
 
  Limitation on Restricted Payments. (a) The Company shall not, and shall not

    (iv) make any Investment in any Person, including, without limitation,
  any Unrestricted Subsidiary (other than a Permitted Investment)
 
(the foregoing actions described in clauses (i) through (iv) above being
hereinafter collectively referred to as "Restricted Payments") unless after
giving effect to the proposed Restricted Payment, (A) no Default or Event of
Default shall have occurred and be continuing and such Restricted Payment
shall not cause or constitute a Default or an Event of Default; (B)
immediately before and immediately after giving effect to such transaction on
a pro forma basis, the Company could incur $1.00 of additional Indebtedness
pursuant to paragraph (a) under "Limitation of Indebtedness"; and (C) the

    (i) 50% of the aggregate cumulative Consolidated Net Income (or, if such
  aggregate cumulative Consolidated Net Income shall be a loss, minus 100% of
  such loss) of the Company accrued on a cumulative basis during the period
  (taken as one accounting period) from the fiscal quarter that first begins
  after the Issue Date to the end of the Company's most recently ended fiscal
  quarter for which internal financial statements are available at the time
  of such Restricted Payment;
 
    (ii) the aggregate Net Cash Proceeds received after the Issue Date by the

    (iv) the aggregate Net Cash Proceeds received after the Issue Date by the
  Company from Indebtedness of the Company or Disqualified Capital Stock of
  the Company that has been converted into or exchanged for Capital Stock

  the Company or Disqualified Capital Stock of the Company was originally
  incurred or issued for cash, plus the aggregate Net Cash Proceeds received
  by the Company at the time of such conversion or exchange;
 
    (v) to the extent not included in Consolidated Net Income, the net
  reduction (received by the Company or any Restricted Subsidiary in cash) in

  (e) Notwithstanding the foregoing, and in the case of clauses (v) and (vii)
below, so long as there is no Default or Event of Default continuing, the
foregoing provisions shall not prohibit the following actions:
 
    (i) the payment of any dividend within 60 days after the date of
  declaration thereof, if at such date of declaration such payment would be
  permitted by the provisions of paragraph (a) of this "Limitation on
  Restricted Payments" covenant (such payment being deemed to have been paid
  on such date of declaration for purposes of the calculation required by
  paragraph (a) of this "Limitation on Restricted Payments" covenant);

  any shares of any class of Capital Stock of the Company or warrants,

  rights to acquire such Capital Stock;
 
    (iii) any repurchase, redemption, defeasance, retirement, refinancing or
  acquisition for value or payment of principal of any Subordinated

  warrants, options or other rights to acquire such Capital Stock;
 
    (iv) the repurchase, redemption, defeasance, retirement or other

  Indebtedness through the issuance of Refinancing Indebtedness;
 
    (v) Investments in Permitted Foreign Companies in a net aggregate amount
  not to exceed $10.0 million in any fiscal year, provided, however, that, to
  the extent the net aggregate amount of such Investments in any fiscal year
  is less than $10.0 million, 50% of such difference may be carried forward
  and added to the $10.0 million permitted amount for the subsequent fiscal
  year;
 
    (vi) Investments in Cheminor Drugs Limited and Dr. Reddy's Laboratories
  Limited having an aggregate fair market value, taken together with all
  other Investments made pursuant to this clause (vi) that are at the time

    (vii) Additional Investments (including, without limitation, Unrestricted
  Subsidiaries) having an aggregate fair market value, taken together with
  all other Investments made pursuant to this clause (vii) that are at the
  time outstanding, not to exceed $15.0 million at the time of such
  Investment (with the fair market value of each Investment being measured at
  the time made and without giving effect to subsequent changes in value).
 
The actions described in clauses (i) and (vii) of this paragraph (b) shall be
Restricted Payments that shall be permitted to be taken in accordance with
this paragraph (b) but shall reduce the amount that would otherwise be
available for Restricted Payments under clause (C) of paragraph (a) of this
"Limitation on Restricted Payments" covenant (provided that any dividend paid
pursuant to clause (i) of this paragraph (b) shall reduce the amount that
would otherwise be available under clause (C) of paragraph (a) of this

paid pursuant to such clause (i)) and the actions described in clauses (ii),
(iii), (iv), (v) and (vi) of this paragraph (b) shall be permitted to be taken

Restricted Subsidiary to, directly or indirectly, incur, assume or suffer to
exist any Lien of any kind upon any of its property or assets (including any
shares of Capital Stock or Indebtedness of any Restricted Subsidiary), whether
owned on the Issue Date or acquired after the Issue Date, or any income or
profits therefrom, except if the Notes (or the Guarantee of the Notes, in the
case of Liens on properties or assets of any Guarantor) and all other amounts
due under the Indenture are directly secured equally and ratably with (or
prior to in the case of Liens with respect to
 
                                      85
<PAGE>
 
Subordinated Indebtedness) the obligation or liability secured by such Lien,
excluding, however, from the operation of the foregoing any of the following:
 
    (a) any Lien existing as of the Issue Date;
 
    (b) any Lien arising by reason of (i) any judgment, decree or order of
  any court, so long as such Lien is in existence less than 30 days after the
  entry thereof or adequately bonded or the payment of such judgment, decree
  or order is covered (subject to a customary deductible) by insurance
  maintained with responsible insurance companies; (ii) taxes, assessments or
  other governmental charges that are not yet delinquent or are being
  contested in good faith; (iii) security for payment of workers'
  compensation or other insurance; (iv) good faith deposits in connection
  with tenders, leases or contracts (other than contracts for the payment of
  borrowed money); (v) zoning restrictions, easements, licenses,

  leasehold interests, mortgages, obligations, liens and other encumbrances
  incurred, created, assumed or permitted to exist and arising by, through or
  under a landlord or owner of the leased property, with or without consent
  of the lessee), none of which materially impairs the use of any property or
  assets material to the operation of the business of the Company or any
  Restricted Subsidiary or the value of such property or assets for the
  purpose of such business; (vi) deposits to secure public or statutory
  obligations, or in lieu of surety or appeal bonds with respect to matters
  not yet finally determined and being contested in good faith by
  negotiations or by appropriate proceedings that suspend the collection
  thereof; or (vii) operation of law in favor of mechanics, materialmen,
  laborers, employees or suppliers, incurred in the ordinary course of
  business for sums that are not yet delinquent or are being contested in
  good faith by negotiations or by appropriate proceedings that suspend the
  collection thereof;
 
    (c) any Lien now or hereafter existing on property or assets of the
  Company or any Guarantor securing Indebtedness of such Person incurred
  pursuant to the Senior Credit Agreement;
 
    (d) any Lien securing Acquired Indebtedness created prior to (and not
  created in connection with, or in contemplation of) the incurrence of such
  Indebtedness by the Company or a Restricted Subsidiary; provided that any
  such Lien extends only to the assets that were subject to such Lien
  securing such Acquired Indebtedness prior to the related acquisition;
 
    (e) leases or subleases granted by the Company or any of its Subsidiaries
  to any other Person in the ordinary course of business;
 
    (f) Liens in the nature of trustees' Liens granted pursuant to any
  indenture governing any indebtedness permitted by the "Limitation on
  Indebtedness" covenant in each case in favor of the trustee under such
  indenture and securing only obligations to pay any compensation to such
  trustee, to reimburse its expenses and to indemnify it under the terms
  thereof;
 
    (g) Liens to secure Indebtedness (including Capitalized Lease
  Obligations) permitted by clause (vii) of paragraph (b) of the "Limitation
  on Indebtedness" covenant covering only the assets acquired with such
  Indebtedness; and
 
    (h) any extension, renewal, refinancing or replacement, in whole or in
  part, of any Lien described in the foregoing clauses (a) through (g) so
  long as the amount of property or assets subject to such Lien is not
  increased thereby.
 
  Limitations on Lines of Business. The Company shall not, and shall not
permit its Restricted Subsidiaries to, engage in any business other than those
engaged in on the date of the Indenture and any other segment of the
pharmaceutical or health-care industry or ancillary thereto.
 
  Commission Reports. Notwithstanding that the Company may not be subject to
the reporting requirements of Sections 13 or 15(d) of the Exchange Act, so
long as any Notes are outstanding, the Company will furnish to the Trustee and
the holders of Notes (i) within 45 days after the end of each of the first
three fiscal quarters of
 
                                      86
<PAGE>
 
each fiscal year and 90 days of the end of each fiscal year all quarterly and
annual financial information, as the case may be, that would be required to be
contained in a filing with the Commission on Forms 10-Q and 10-K if the
Company were required to file any such Forms, including a "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and,
with respect to the annual information only, a report thereon by the Company's
certified independent accountants and (ii) all current reports that would be
required to be filed with the Commission on Form 8-K if the Company were
required to file such reports. In addition, whether or not required by the
rules and regulations of the Commission, the Company will file a copy of all
such information and reports with the Commission for public availability
(unless the Commission will not accept such a filing) and make such
information available to securities analysts and prospective investors upon
request. Furthermore, for so long as any of the Notes remain outstanding, the
Company has agreed to make available to any prospective purchaser of the Notes
or beneficial owner of the Notes, in connection with any sale thereof, the
information required by Rule 144(d)(4) under the Securities Act.
 
  Limitation on Restrictions on Distributions from Restricted
Subsidiaries. The Company shall not, and shall not permit any Restricted
Subsidiary to, create or otherwise cause or permit to exist or become
effective any consensual encumbrance or restriction on the ability of any
Restricted Subsidiary (a) to pay dividends or make any other distributions on
its Capital Stock or pay any Indebtedness owed to the Company or any
Restricted Subsidiary, (b) to make any loans or advances to the Company or any
Restricted Subsidiary or (c) to transfer any of its property or assets to the
Company or any Restricted Subsidiary, except: (i) any encumbrance or
restriction pursuant to an agreement in effect at or entered into on the Issue
Date; (ii) any encumbrance or restriction with respect to a Restricted
Subsidiary pursuant to an agreement relating to any Indebtedness incurred by
such Restricted Subsidiary on or prior to the date on which such Restricted
Subsidiary was acquired by the Company (other than Indebtedness incurred as
consideration in, or to provide all or any portion of the funds or credit
support utilized to consummate, the transaction or series of related
transactions pursuant to which such Restricted Subsidiary became a Restricted
Subsidiary or was acquired by the Company) and outstanding on such date; (iii)
any encumbrance or restriction pursuant to an agreement effecting a
refinancing of Indebtedness incurred pursuant to an agreement referred to in
clause (i) or (ii) of this covenant or contained in any amendment to an
agreement referred to in clause (i) or (ii) of this covenant; provided,
however, that the encumbrances and restrictions with respect to such
Restricted Subsidiary contained in any such refinancing agreement or amendment
are no less favorable in any material respect to the holders of the Notes than
encumbrances and restrictions with respect to such Restricted Subsidiary
contained in such agreements; (iv) in the case of clause (c) above, any
encumbrance or restriction (A) that restricts in a customary manner the
subletting, assignment or transfer of any property or asset that is a lease,
license, conveyance or contract or similar property or asset that is the
subject of such encumbrance or restriction, (B) existing by virtue of any
transfer of, agreement to transfer, option or right with respect to, or Lien
on, any property or assets of the Company or any Restricted Subsidiary not
otherwise prohibited by the Indenture or (C) arising or agreed to in the
ordinary course of business, not relating to any Indebtedness, and that do
not, individually or in the aggregate, detract from the value of property or
assets of the Company or any Restricted Subsidiary in any manner material to
the Company or any Restricted Subsidiary; provided that, in each case, such
encumbrance or restriction relates to, and restricts dealings with, only the
property or asset that is the subject of such encumbrance or restriction; and
provided, further, that such encumbrance or restriction does not prohibit,
limit or otherwise restrict the making or payment of any dividend or other
distribution to the Company or any Restricted Subsidiary; (v) any restriction
with respect to a Restricted Subsidiary imposed pursuant to an agreement
entered into for the sale or disposition of all or substantially all the
Capital Stock or assets of such Restricted Subsidiary pending the closing of
such sale or disposition; and (vi) any restrictions on cash or other deposits
or net worth imposed by customers under contracts entered into in the ordinary
course of business.
 
  Limitation on Sales of Assets and Subsidiary Stock. (a) The Company shall
not, and shall not permit any Restricted Subsidiary to, make any Asset
Disposition unless (i) the Company or such Restricted Subsidiary receives
consideration (including by way of relief from, or by any other Person
assuming sole responsibility for, any liabilities, contingent or otherwise) at
the time of such Asset Disposition at least equal to the Fair Market Value of
the shares or assets that are the subject matter of such Asset Disposition,
(ii) at least 80% of the
 
                                      87
<PAGE>
 
consideration therefor received by the Company or such Restricted Subsidiary
is in the form of cash and (iii) an amount equal to 100% of the Net Available
Cash from such Asset Disposition is applied by the Company (or such Restricted
Subsidiary, as the case may be) (A) first, to the extent the Company elects
(or is required by the terms of the Senior Credit Agreement), to prepay, repay
or purchase such indebtedness incurred under the Senior Credit Agreement
within 180 days after the later of the date of such Asset Disposition or the
receipt of such Net Available Cash, (B) second, to the extent of the balance
of Net Available Cash after application in accordance with clause (A), to the
extent the Company elects, to secure letter of credit obligations to the
extent such related letters of credit have not been drawn upon or returned
undrawn; (C) third, to the extent of the balance of Net Available Cash after
application in accordance with clauses (A) and (B), to the extent the Company
or such Restricted Subsidiary elects, within one year from the later of the
date of such Asset Disposition or the receipt of such Net Available Cash, to
reinvest in, Additional Assets; and (D) fourth, to the extent of the balance
of such Net Available Cash after application in accordance with clauses (A),
(B) and (C), to make an offer to purchase Notes pursuant and subject to the
conditions of the Indenture to the holders of the Notes at a purchase price of
100% of the principal amount thereof plus accrued and unpaid interest to the
purchase date; provided, however, that, in connection with any prepayment,
repayment or purchase of Indebtedness pursuant to clause (A) or (B) above, the
Company or such Restricted Subsidiary shall retire such Indebtedness and shall
cause the related loan commitment (if any) to be permanently reduced in an
amount equal to the principal amount so prepaid, repaid or purchased. The
Company shall not be required to make an offer for Notes pursuant to this
covenant if the Net Available Cash available therefor (after application of
the proceeds as provided in clauses (A), (B) and (C)) is less than $15.0
million (which lesser amount shall be carried forward for purposes of
determining whether an offer is required with respect to the Net Available
Cash from any subsequent Asset Disposition).
 
  For the purposes of clause (a)(ii) of this covenant, the following will be
deemed to be cash: (x) the assumption of Indebtedness (other than Disqualified
Capital Stock) of the Company or any Restricted Subsidiary and the release of
the Company or such Restricted Subsidiary from all liability on such
Indebtedness in connection with such Asset Disposition and (y) securities
received by the Company or any Restricted Subsidiary of the Company from the
transferee that are promptly converted by the Company or such Restricted
Subsidiary into cash.
 
  (b) In the event of an Asset Disposition that requires the purchase of Notes
pursuant to clause (a)(iii)(D) of this covenant, the Company will be required
to purchase Notes tendered pursuant to an offer by the Company for the Notes
at a purchase price of 100% of their principal amount plus accrued interest to
the purchase date in accordance with the procedures (including prorating in
the event of oversubscription) set forth in the Indenture.
 
  (c) The Company shall comply with the applicable tender offer rules,
including Rule 14e-1 under the Exchange Act, and any other securities laws or
regulations in connection with the repurchase of Notes pursuant to this
covenant.
 
  Limitation on Affiliate Transactions. The Company shall not, and shall not
permit any Restricted Subsidiary to, directly or indirectly, enter into or
conduct any transaction (including the purchase, sale, lease or exchange of
any property or the rendering of any service) with any Affiliate of the
Company (an "Affiliate Transaction") unless: (i) the terms of such Affiliate
Transaction are no less favorable to the Company or such Restricted
Subsidiary, as the case may be, than those that could be obtained at the time
of such transaction in arm's-length dealings with a Person who is not an
Affiliate; (ii) in the event such Affiliate Transaction involves an aggregate
amount in excess of $1.0 million (unless such Affiliate Transaction
constitutes an agreement with Bayer A.G. or its Affiliate relating to an
Investment by the Company and an Investment by Bayer A.G. or its Affiliate in
a Permitted Foreign Company in which case the requirements of this clause
shall be applicable only if the amount being invested by the Company exceeds
$10.0 million), the terms of such transaction have been approved by a majority
of the members of the Board of Directors of the Company and by a majority of
the disinterested members of such Board, if any (and such majority or
majorities, as the case may be, determines that such Affiliate Transaction
satisfies the criteria in (i) above) and (iii) in the event such Affiliate
Transaction involves an aggregate amount in excess of $15.0 million (unless
such Affiliate Transaction constitutes an agreement with Bayer A.G. or its
Affiliate relating to an Investment by the Company and an Investment by Bayer
 
                                      88
<PAGE>
 
A.G. or its Affiliate in a Permitted Foreign Company in which case the
requirements of this clause shall be applicable only if the amount being
invested by the Company exceeds $25.0 million), the Company has received a
written opinion from an independent investment banking firm of nationally
recognized standing that such Affiliate Transaction is fair to the Company or
such Restricted Subsidiary, as the case may be, from a financial point of
view.
 
  The provisions of the foregoing paragraph will not prohibit (i) any
Restricted Payment permitted to be paid or made pursuant to the covenant
described under "Limitation on Restricted Payments," (ii) the performance of
the Company's or a Restricted Subsidiary's obligations under any employment
contract, stock option, collective bargaining agreement, employee benefit
plan, related trust agreement or any other similar arrangement heretofore or
hereafter entered into in the ordinary course of business, (iii) payment of
compensation to employees, officers, directors or consultants in the ordinary
course of business, (iv) maintenance in the ordinary course of business of
benefit programs or arrangements for employees, officers or directors,
including vacation plans, health and life insurance plans, deferred
compensation plans, and retirement or savings plans and similar plans, (v) any
transaction between the Company and a Restricted Subsidiary or between
Restricted Subsidiaries, (vi) any agreement in effect as of the Issue Date or
any amendment thereto or any transaction contemplated thereby, (vii)
transactions required of the Company or any Restricted Subsidiary under, or
contemplated by, the General Shareholders Agreement dated September 30, 1994,
and the Continuing Shareholders Agreement dated September 30, 1994, in each
case as in effect on the date of this Indenture or (viii) any agreement
entered into in the ordinary course or business between the Company and a
Person who constitutes an Affiliate solely by reason of such Person being an
officer or director of the Company which agreement provides for the repurchase
by the Company, upon or following the termination of such Person's employment
or directorship with the Company, of shares of Capital Stock of the Company
owned by such Person.
 
  Limitation on Sale of Capital Stock of Restricted Subsidiaries. The Company
(i) shall not, and shall not permit any Restricted Subsidiary to, transfer,
convey, sell or otherwise dispose of any Capital Stock of any Restricted
Subsidiary to any Person (other than to the Company or a Restricted
Subsidiary) and (ii) shall not permit any Restricted Subsidiary to issue any
of its Capital Stock to any Person other than to the Company or a Restricted
Subsidiary; provided, however, that the foregoing shall not prohibit the
transfer, conveyance, sale or other disposition of all the Capital Stock of a
Restricted Subsidiary if the Net Cash Proceeds from such transfer, conveyance,
sale or other disposition are applied in accordance with the covenant
described above under "Limitation on Sales of Assets and Subsidiary Stock";
and, provided, further, that this covenant shall not prohibit the transfer,
conveyance, sale or other disposition of less than all of the Capital Stock of
a Restricted Subsidiary or the issuance by any Restricted Subsidiary of any of
its Capital Stock to any Person as long as (A) the Net Cash Proceeds from such
transfer, conveyance, sale or other disposition or issuance are applied in
accordance with the "Limitation on Sales of Assets and Subsidiary Stock"
covenant, (B) immediately after giving effect to such transaction, no Event of
Default shall have occurred and be continuing, (C) immediately after giving
pro forma effect to such transaction, as if such transaction had occurred at
the beginning of the applicable four-quarter period, the Company would be
permitted to incur at least $1.00 of additional Indebtedness pursuant to the
Consolidated Coverage Ratio test as set forth in paragraph (a) of the
"Limitation on Indebtedness" covenant and (D) immediately after giving effect
to such transaction, such Restricted Subsidiary remains a Restricted
Subsidiary of the Company.
 
  Limitation on Sale and Leaseback Transactions. The Indenture will provide
that the Company shall not, and shall not permit any of its Restricted
Subsidiaries to, enter into any sale and leaseback transaction; provided that
the Company may enter into a sale and leaseback transaction if (i) the Company
could have (a) incurred Indebtedness in an amount equal to the Attributable
Debt (as defined herein) relating to such sale and leaseback transaction
pursuant to the Consolidated Coverage Ratio test set forth in paragraph (a) of
the covenant "Limitation on Indebtedness" and (b) incurred a Lien to secure
such Indebtedness pursuant to the "Limitation on Liens" covenant, (ii) the
gross cash proceeds of such sale and leaseback transaction are at least equal
to the fair market value (as determined in good faith by the Board of
Directors and set forth in an Officers' Certificate delivered to the Trustee)
of the property that is the subject of such sale and leaseback transaction and
(iii) the
 
                                      89
<PAGE>
 
transfer of assets in such sale and leaseback transaction is permitted by, and
the Company applies the net proceeds of such transaction in compliance with,
the "Limitation on Sales of Assets and Subsidiary Stock" covenant.
 
MERGER AND CONSOLIDATION
 
  The Company shall not consolidate with or merge with or into, or convey,
transfer or lease all or substantially all its assets to, any Person, unless:
(i) the resulting, surviving or transferee Person (the "Successor Company")
shall be a Person organized and existing under the laws of the United States
of America, any state thereof or the District of Columbia and the Successor
Company (if not the Company) shall expressly assume, by an indenture
supplemental to the Indenture, executed and delivered to the Trustee, in form
reasonably satisfactory to the Trustee, all the obligations of the Company
under the Notes and the Indenture; (ii) immediately after giving effect to
such transaction (and treating any Indebtedness which becomes an obligation of
the Successor Company or any Restricted Subsidiary as a result of such
transaction as having been incurred by such Successor Company or such
Restricted Subsidiary at the time of such transaction), no Event of Default
shall have occurred and be continuing; (iii) immediately after giving pro
forma effect to such transaction, as if such transaction had occurred at the
beginning of the applicable four-quarter period, the Successor Company would
be permitted to incur at least $1.00 of additional Indebtedness pursuant to
the Consolidated Coverage Ratio test set forth in paragraph (a) of the
"Limitation on Indebtedness" covenant; and (iv) the Company shall have
delivered to the Trustee an Officers' Certificate and an Opinion of Counsel,
each stating that such consolidation, merger or transfer and each supplemental
indenture (if any) comply with the Indenture.
 
  The Successor Company shall be the successor of the Company and shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company under the Indenture, but the predecessor Company in the case of a
conveyance, transfer or lease shall not be released from the obligation to pay
the principal of and interest on the Notes.
 
EVENTS OF DEFAULT
 
  An Event of Default is defined in the Indenture as (i) a default in any
payment of interest on any Note when due and payable, continued for 30 days,
(ii) a default in the payment of principal of any Note when due and payable at
its Stated Maturity, upon optional redemption, upon required repurchase, upon
declaration or otherwise, (iii) the failure by the Company to comply with its
obligations under "--Merger and Consolidation," (iv) the failure by the
Company to comply for 30 days after notice with any of its obligations under
"--Change of Control" or under the covenants described under "Certain
Covenants" above (in each case, other than a failure to purchase Notes which
shall constitute an Event of Default under clause (ii) above), (v) the failure
by the Company to comply for 30 days after notice with its other covenants and
agreements contained in the Indenture or the Notes, (vi) Indebtedness of the
Company or any Restricted Subsidiary is not paid within any applicable grace
period after final maturity or is accelerated by the holders thereof because
of a default and the total amount of such Indebtedness unpaid or accelerated
exceeds $10.0 million or its foreign currency equivalent at the time (the
"cross acceleration provision"), (vii) certain events of bankruptcy,
insolvency or reorganization of the Company or a Material Subsidiary (the
"bankruptcy provisions"), (viii) any judgment or decree for the payment of
money in excess of $10.0 million or its foreign currency equivalent at the
time (to the extent not covered by insurance) is entered against the Company
or a Material Subsidiary and is not discharged and either (A) an enforcement
proceeding has been commenced by any creditor upon such judgment or decree and
is not promptly stayed or (B) such judgment or decree shall remain
undischarged or unstayed for a period of 60 days following the entry of such
judgment or decree (the "judgment default provision") or (ix) the failure of
any Subsidiary Guarantee of the Notes to be in full force and effect (except
as contemplated by the terms thereof) or the denial or disaffirmation by any
Guarantor of its obligations under the Indenture or any Subsidiary Guarantee
of the Notes if such failure is not cured, or such denial or disaffirmation is
not rescinded or revoked, within 10 days. However, a default under clauses
(iv) and (v) will not constitute an Event of Default until the Trustee or the
holders of at least 25% in principal amount of the outstanding Notes notify
the Company in writing of the
 
                                      90
<PAGE>
 
default and the Company does not cure such default within the time specified
in clauses (iv) and (v) hereof after receipt of such notice.
 
  If an Event of Default (other than an Event of Default specified in clause
(vii) above with respect to the Company) occurs and is continuing, the
Trustee, by written notice to the Company, or the holders of at least 25% in
outstanding principal amount of the Notes, by written notice to the Company
and the Trustee, may declare the principal of, and accrued and unpaid interest
on, all the Notes to be due and payable. Upon such a declaration, such
principal and interest shall be due and payable (i) if no Indebtedness is
outstanding under the Senior Credit Agreement, immediately, and (ii) if any
Indebtedness is outstanding under the Senior Credit Agreement, upon the first
to occur of (x) the acceleration of any such Indebtedness or (y) the fifth
Business Day after receipt by the Company and the Credit Agent of such written
notice of acceleration. If an Event of Default specified in clause (vii) above
occurs and is continuing, the principal of, and accrued and unpaid interest
on, all the Notes shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any
holders. Under certain circumstances, the holders of a majority in principal
amount of the outstanding Notes may rescind any such acceleration with respect
to the Notes and its consequences.
 
  Subject to the provisions of the Indenture relating to the duties of the
Trustee, if an Event of Default occurs and is continuing, the Trustee will be
under no obligation to exercise any trust or power under the Indenture at the
request, order or direction of any of the holders unless such holders have
offered to the Trustee indemnification satisfactory to it in its sole
discretion against all losses and expenses. Except to enforce the right of any
holder to receive payment of the principal of and interest on the Notes held
by such holder on or after the respective due dates expressed in the Notes, no
holder may pursue any remedy with respect to the Indenture or the Notes unless
(i) such holder has previously given the Trustee notice that an Event of
Default is continuing, (ii) holders of at least 25% in outstanding principal
amount of the outstanding Notes have requested the Trustee to pursue the
remedy, (iii) such holders have offered the Trustee reasonable security or
indemnity against any loss, liability or expense, (iv) the Trustee has not
complied with such request within 60 days after the receipt of the request and
the offer of security or indemnity, and (v) the holders of a majority in
principal amount of the outstanding Notes have not given the Trustee a
direction that is inconsistent with such request within such 60 day period.
Subject to certain restrictions, the holders of a majority in outstanding
principal amount of the Notes may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee
may refuse to follow any direction that conflicts with law or the Indenture
or, subject to the provisions of the Indenture relating to the duties of the
Trustee, that the Trustee determines is unduly prejudicial to the rights of
other holders (it being understood that, subject to the provisions of the
Indenture relating to the duties of the Trustee, the Trustee shall have no
duty to ascertain whether or not such actions or forbearances are unduly
prejudicial to such holders) or would subject the Trustee to personal
liability; provided, however, that the Trustee may take any other action
deemed proper by the Trustee that is not inconsistent with such direction.
Prior to taking or refraining from taking any such action hereunder, the
Trustee shall be entitled to indemnification satisfactory to it in its sole
discretion against all losses and expenses caused by its taking or refraining
from taking such action.
 
  The Indenture provides that if a Default or Event of Default occurs and is
continuing and if a Trust Officer has actual knowledge thereof, the Trustee
shall mail to each holder notice of the Default or Event of Default within 90
days after it occurs. Except in the case of a Default or Event of Default in
payment of principal of, or interest on, any Note (including payments pursuant
to the optional redemption or required repurchase provisions of such Note, if
any), the Trustee may withhold the notice if and so long as its board of
directors, the Executive Committee of its board of directors or a committee of
its Trust Officers in good faith determines that withholding the notice is in
the interests of the holders of the Notes. In addition, the Company is
required to deliver to the Trustee: (i) within 5 days after the occurrence
thereof, written notice in the form of an Officers' Certificate of any Event
of Default under clause (vi) above and any event which with the giving of
notice or the lapse of time would become an Event of Default under clause
(iv), (v) or (viii), its status and what action the Company is taking or
proposes to take with respect thereto and (ii) within 120 days after the end
of each fiscal year, written notice in the form of an Officers' Certificate
indicating whether the officers signing such Officers' Certificate had actual
knowledge of any Default that occurred during such previous fiscal year.

AMENDMENTS AND WAIVERS
 
  Subject to certain exceptions, the Indenture may be amended with the consent
of the holders of a majority in principal amount of the Notes then outstanding
and any past default or compliance with any provisions may be waived with the
consent of the holders of a majority in principal amount of the Notes then
outstanding. However, without the consent of each holder of an outstanding
Note affected, no amendment may, among other things, (i) reduce the amount of
Notes whose holders must consent to an amendment, (ii) reduce the rate of or
extend the time for payment of interest on any Note, (iii) reduce the
principal of or extend the Stated Maturity of any Note, (iv) reduce the
premium payable upon the redemption or repurchase of any Note or change the
time at which any Note may or shall be redeemed or repurchased in accordance
with the Indenture, (v) make any Note payable in money other than that stated
in the Note, (vi) modify or affect in any manner adverse to the holders of the
Notes, the terms and conditions of the obligation of the Company for the due
and punctual payment of the principal of or interest on the Notes or (vii)
make any change in the amendment provisions which require each holder's
consent or in the waiver provisions.
 
  Without the consent of any holder, the Company and the Trustee may amend the
Indenture to cure any ambiguity, omission, defect or inconsistency, to provide
for the assumption by a successor corporation of the obligations of the
Company under the Indenture, to provide for uncertificated Notes in addition
to or in place of certificated Notes (provided that the uncertificated Notes
are issued in registered form for purposes of Section 163(f) of the Code, or
in a manner such that the uncertificated Notes are described in Section
163(f)(2)(B) of the Code), to add Guarantees with respect to the Notes, to
secure the Notes, to add to the covenants of the Company for the benefit of
the holders of the Notes or to surrender any right or power conferred upon the
Company, to make any change that does not adversely affect the rights of any
holder or to comply with any requirement of the Commission in connection with
the qualification of the Indenture under the Trust Indenture Act.
 
  The consent of the holders is not necessary under the Indenture to approve
the particular form of any proposed amendment. It is sufficient if such
consent approves the substance of the proposed amendment.
 
  After an amendment under the Indenture becomes effective, the Company is
required to mail to the holders a notice briefly describing such amendment.
However, the failure to give such notice to all the holders, or any defect
therein, will not impair or affect the validity of the amendment.
 
TRANSFER AND EXCHANGE
 
  A holder of Notes may transfer or exchange Notes in accordance with the
Indenture. The Company or the Trustee may require any Note presented for
registration of transfer, exchange, redemption or payment to be duly endorsed
by, or be accompanied by a written instrument or instruments of transfer in
form satisfactory to the Company and the Trustee duly executed by, the holder
or his attorney duly authorized in writing. The Company may require payment of
a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any exchange or registration of transfer of Notes.
No service charge may be imposed for any such transaction. The Trustee may not
be required to exchange or register a transfer of (i) any Notes for a period
of 15 days next preceding the first mailing of notice of redemption of Notes
to be redeemed or (ii) any Notes selected, called or being called for
redemption except, in the case of any Note where public notice has been given
that such Note is to be redeemed in part, the portion thereof not so to be
redeemed. The Notes will be issued in registered form and the registered
holder of a Note will be treated as the owner of such Note for all purposes.
 
DEFEASANCE
 
  Subject to certain conditions and to the survival of certain of the
Company's obligations under the Indenture, the Company at any time may
terminate (i) all its obligations under the Notes and the Indenture and all
obligations of the Subsidiary Guarantors under the Subsidiary Guarantee and
the Indenture ("legal defeasance option") or (ii) its obligations under
certain covenants described under "Certain Covenants," the operation of
 
                                      92
<PAGE>
 
the cross acceleration provision and the judgement default provision described
under "Events of Default" above and the limitations contained in clauses (iii)
and (iv) under "--Merger and Consolidation" above ("covenant defeasance"). The
Senior Credit Agreement prohibits the legal defeasance and covenant defeasance
of the Notes as long as there are obligations outstanding under the Senior
Credit Agreement. However, no deposit of funds shall be effective to terminate
the obligations of the Company under the Notes or the Indenture prior to 123
days following any such deposit.
 
  The Company may exercise its legal defeasance option notwithstanding its
prior exercise of its covenant defeasance option. If the Company exercises its
legal defeasance option, payment of the Notes may not be accelerated because
of an Event of Default. If the Company exercises its covenant defeasance
option, payment of the Notes may not be accelerated because of an Event of
Default specified in clause (iv), (v), (vi), (viii) or (ix) under "Events of
Default" above or because of the failure of the Company to comply with clause
(iii) or (iv) under "--Merger and Consolidation" above.
 
  In order to exercise either defeasance option, the Company must irrevocably
deposit in trust (the "defeasance trust") with the Trustee money or U.S.
Government Obligations for the payment of principal of and interest on the
Notes to maturity or redemption, as the case may be, and must comply with
certain other conditions, including delivery to the Trustee of an Opinion of
Counsel to the effect that holders of the Notes will not recognize income,
gain or loss for federal income tax purposes as a result of such defeasance
and will be subject to federal income tax on the same amounts, in the same
manner and at the same times as would have been the case if such defeasance
had not occurred (and, in the case of legal defeasance only, such Opinion of
Counsel must be based on a ruling of the Internal Revenue Service or other
change in applicable federal income tax law).
 
CONCERNING THE TRUSTEE
 
  The Bank of New York is to be the Trustee under the Indenture and has been
appointed by the Company as Registrar and Paying Agent with regard to the
Notes. The Bank of New York is a lender under the Senior Credit Agreement.
 
GOVERNING LAW
 
  The Indenture provides that it and the Notes will be governed by, and
construed in accordance with, the laws of the State of New York without giving
effect to applicable principles of conflict of laws to the extent that the
application of the law of another jurisdiction would be required thereby.

BOOK-ENTRY; DELIVERY AND FORM
 
  Except as set forth below, the New Notes will initially be issued in the
form of one or more registered Notes in global form without coupons (each a
"Global Note"). Each Global Note will be deposited upon issuance with, or on
behalf of, the Depository and registered in the name of Cede & Co., as nominee
of the Depository, or will remain in the custody of the Trustee pursuant to
the FAST Balance Certificate Agreement between the Depository and the Trustee.
 
  New Notes that are issued in respect of Notes that were (i) originally
issued to or transferred to institutional "accredited investors," as defined
in Rule 501(a) (1), (3) or (7) under the Securities Act ("Institutional
Accredited Investors"), who are not QIBs or to any other persons who are not
QIBs or (ii) issued as described below under "Certificated Securities," will
be issued in registered definitive form without coupons (the "Certificated
Securities"). Upon the transfer to a QIB of Certificated Securities, such
Certificated Securities may, unless the Global Note has previously been
exchanged for Certificated Securities, be exchanged for an interest in the
Global Note representing the principal amount of Notes being transferred.
 
  The Depository has advised the Company that it is (i) a limited purpose
trust company organized under the laws of the State of New York, (ii) a member
of the Federal Reserve System, (iii) a "clearing corporation" within the
meaning of the Uniform Commercial Code, as amended, and (iv) a "Clearing
Agency" registered pursuant to Section 17A of the Exchange Act. The Depository
was created to hold securities for its participants (collectively, the
"Participants") and facilitates the clearance and settlement of securities
transactions between Participants through electronic book-entry changes to the
accounts of its Participants, thereby eliminating the need for physical
transfer and delivery of certificates. The Depository's Participants include
securities brokers and dealers (including the Initial Purchaser), banks and
trust companies, clearing corporations and certain other organizations. Access
to the Depository's system is also available to other entities such as banks,
brokers, dealers and trust companies (collectively, the "Indirect
Participants") that clear through or maintain a custodial relationship with a
Participant, either directly or indirectly. QIBs may elect to hold Notes
purchased by them through the Depository. QIBs who are not Participants may
beneficially own securities held by or on behalf of the Depository only
through Participants or Indirect Participants. Persons that are not QIBs may
not hold Notes through the Depository.
 
  The Company expects that pursuant to procedures established by the
Depository (i) upon deposit of the Global Notes, the Depository will credit
the accounts of Participants designated by the Initial Purchaser with an
interest in the Global Note and (ii) ownership of the Notes will be shown on,
and the transfer of ownership thereof will be effected only through, records
maintained by the Depository (with respect to the interest of Participants),
the Participants and the Indirect Participants. The laws of some states
require that certain persons take physical delivery in definitive form of
securities that they own and that security interests in negotiable instruments
can only be perfected by delivery of certificates representing the
instruments. Consequently, the ability to transfer Notes or to pledge the
Notes as collateral will be limited to such extent.
 
  So long as the Depository or its nominee is the registered owner of the
Global Note, the Depository or such nominee, as the case may be, will be
considered the sole owner or Holder of the Notes represented by the Global
Note for all purposes under the Indenture. Except as provided below, owners of
beneficial interests in a Global Note will not be entitled to have Notes
represented by such Global Note registered in their names, will not receive or
be entitled to receive physical delivery of Certificated Securities, and will
not be considered the owners or holders thereof under the Indenture for any
purpose, including with respect to giving of any directions, instruction or
approval to the Trustee thereunder. As a result, the ability of a person
having a beneficial interest in Notes represented by a Global Note to pledge
such interest to persons or entities that do not participate in the
Depository's system or to otherwise take action with respect to such interest,
may be affected by the lack of a physical certificate evidencing such
interest.
 
  Accordingly, each QIB owning a beneficial interest in a Global Note must
rely on the procedures of the Depository and, if such QIB is not a Participant
or an Indirect Participant, on the procedures of the Participant
 
                                      103
<PAGE>
 
through which such QIB owns its interest, to exercise any rights of a Holder
under the Indenture or such Global Note. The Company understands that under
existing industry practice, in the event the Company requests any action of
holders or a QIB that is an owner of a beneficial interest in a Global Note
desires to take any action that the Depository, as the Holder of such Global
Note, is entitled to take, the Depository would authorize the Participants to
take such action and the Participant would authorize QIBs owning through such
Participants to take such action or would otherwise act upon the instruction
of such QIBs. Neither the Company nor the Trustee will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of Notes by the Depository, or for maintaining, supervising or
reviewing any records of the Depository relating to such Notes.
 
  Payments with respect to the principal of, premium, if any, and interest on
any Notes represented by a Global Note registered in the name of the
Depository or its nominee on the applicable record date will be payable by the
Paying Agent to or at the direction of the Depository or its nominee in its
capacity as the registered Holder of the Global Note representing such Notes
under the Indenture. Under the terms of the Indenture, the Company and the
Trustee may treat the persons in whose names the Notes, including the Global
Notes, are registered as the owners thereof for the purpose of receiving such
payment and for any and all other purposes whatsoever. Consequently, neither
the Company nor the Trustee nor the Paying Agent (if other than the Trustee)
has or will have any responsibility or liability for the payment of such
amounts to beneficial owners of Notes (including principal, premium, if any,
and interest), or to immediately credit the accounts of the relevant
Participants with such payment, in amounts proportionate to their respective
holdings in principal amount of beneficial interest in the Global Note as
shown on the records of the Depository. Payments by the Participants and the
Indirect Participants to the beneficial owners of Notes will be governed by
standing instructions and customary practice and will be the responsibility of
the Participants or the Indirect Participants.
 
CERTIFICATED SECURITIES
 
  If (i) the Company notifies the Trustee in writing that the Depository is no
longer willing or able to act as a depository and the Company is unable to
locate a qualified successor within 90 days, (ii) the Company, at its option,
notifies the Trustee in writing that it elects to cause the issuance of Notes
in definitive form under the Indenture or (iii) upon the occurrence of certain
other events, then, upon surrender by the Depository of its Global Notes,
Certificated Securities will be issued to each person that the Depository
identifies as the beneficial owner of the Notes represented by the Global
Note. Upon any such issuance, the Trustee is required to register such
Certificated Securities in the name of such person or persons (or the nominee
of any thereof), and cause the same to be delivered thereto.
 
  Neither the Company nor the Trustee shall be liable for any delay by the
Depository or any Participant or Indirect Participant in identifying the
beneficial owners of the related Notes and each such person may conclusively
rely on, and shall be protected in relying on, instructions from the
Depository for all purposes (including with respect to the registration and
delivery, and the respective principal amounts, of the Notes to be issued).

                CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS
 
  The following discussion is based upon current provisions of the Internal
Revenue Code of 1986, as amended, applicable Treasury regulations, judicial
authority and administrative ruling and practice. There can be no assurance
that the Internal Revenue Service (the "IRS") will not take a contrary view,
and no rules from the IRS has been or will be sought. Legislative, judicial or
administrative changes or interpretations may be forthcoming that could alter
or modify the statements and conditions set forth herein. Any such changes or
interpretations may or may not be retroactive and could affect the tax
consequences to holders. Certain holders (including insurance companies, tax-
exempt organizations, financial institutions, broker-dealers, foreign
corporations and persons who are not citizens or residents of the United
States) may be subject to special rules and not discussed below. The Company
recommends that each holder consult such holder's own tax adviser as to the
particular tax consequences of exchanging such holder's Old Notes for New
Notes, including the applicability and effect of any state, local or foreign
tax laws.
 
  The Company believes that the exchange of Old Notes for New Notes pursuant
to the Exchange Offer will not be treated as an "exchange" for federal income
tax purposes because the New Notes will not be considered to differ materially
in kind or extent from the Old Note. Rather, the New Notes received by a
holder will be treated as a continuation of the Old Notes in the hands of such
holder. As a result, there will be no federal income tax consequence to
holders exchanging Old Notes for New Notes pursuant to the Exchange Offer.
 
                             PLAN OF DISTRIBUTION
 
  Each Participating Broker-Dealer that receives New Notes for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such New Notes. This Prospectus,
as it may be amended or supplemented from time to time, may be used by a
Participating Broker-Dealer in connection with resales of New Notes received
in exchange for Old Notes where such Old Notes were acquired as a result of
market-making activities or other trading activities. The Company has agreed
that, for a period of 90 days after the Expiration Date, it will make this
Prospectus available to any Participating Broker-Dealer for use in connection
with any such resale. Until           , 1998 (90 days after the commencement
of the Exchange Offer), all dealers effecting transactions in the New Notes,
whether or not participating in this distribution, may be required to deliver
a prospectus.
 
  The Company will not receive any proceeds from any sales of the New Notes by
Participating Broker-Dealers. New Notes received by Participating Broker-
Dealers for their own account pursuant to the Exchange Offer may be sold from
time to time in one or more transactions in the over-the-counter market, in
negotiated transactions, through the writing of options on the New Notes or a
combination of such methods of resale, at prices related to such prevailing
market prices or negotiated prices. Any such resale may be made directly to
purchasers or to or through brokers or dealers who may receive compensation in
the form of commissions or concessions from any such Participating Broker-
Dealer and/or the purchasers of any such New Notes. Any Participating Broker-
Dealer that resells the New Notes that were received by it for its own account
pursuant to the Exchange Offer and any broker or dealer that participates in a
distribution of such New Notes may be deemed to be an "underwriter" within the
meaning of the Securities Act and any profit or any such resale of New Notes
and any commissions or concessions received by any such persons may be deemed
to be underwriting compensation under the Securities Act. The Letter of
Transmittal states that by acknowledging that it will deliver and by
delivering a Prospectus, a Participating Broker-Dealer will not be deemed to
admit that it is an "underwriter" within the meaning of the Securities Act.
 
  For a period of 90 days after the Expiration Date the Company will promptly
send additional copies of the Prospectus and any amendment or supplement to
this Prospectus to any broker-dealer that requests such documents in a Letter
of Transmittal. The Company agreed to pay all expenses incident to the
Exchange Offer other than commissions or concessions of any broker-dealers and
will indemnify holders of the Notes (including any broker-dealer) against
certain liabilities, including liabilities under the Securities Act.

              REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
Board of Directors
Schein Pharmaceutical, Inc.
 
  We have audited the accompanying consolidated balance sheets of Schein
Pharmaceutical, Inc. and subsidiaries as of December 30, 1995 and December 28,
1996, and the related consolidated statements of operations, stockholders'
equity and cash flows for each of the three years in the period ended December
28, 1996. These consolidated financial statements are the responsibility of
the management of Schein Pharmaceutical, Inc. and subsidiaries. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the consolidated financial
statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the
consolidated financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as
well as evaluating the overall consolidated financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of Schein Pharmaceutical, Inc. and subsidiaries as of December 30, 1995 and
December 28, 1996, and the consolidated results of their operations and their
cash flows for each of the three years in the period ended December 28, 1996
in conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
      (INFORMATION AS OF SEPTEMBER 27, 1997 AND FOR THE NINE-MONTHS ENDED
            SEPTEMBER 28, 1996 AND SEPTEMBER 27, 1997 IS UNAUDITED)
NOTE 1--SUMMARY OF ACCOUNTING POLICIES
 
  The Company and Principles of Consolidation
 
  Schein Pharmaceutical, Inc. and its subsidiaries (the "Company") are engaged
in developing, manufacturing, marketing and distributing generic
pharmaceutical products and a line of specialty branded pharmaceuticals. The
Company sells to drug store chains, independent retail pharmacies, managed
care organizations, hospitals and other institutions, both through drug
wholesalers and directly, primarily in the U.S.
 
  The Company's Board of Directors authorized the filing of a registration
statement with the Securities and Exchange Commission permitting the Company
to sell shares of its common stock in a proposed initial public offering. In
connection with the proposed offering, the Company, on       , 1998, effected
a 123-for-one stock split, and increased its authorized common stock to
100,000,000 shares. All applicable share and per share amounts in the
accompanying consolidated financial statements have been retroactively
adjusted to reflect the stock split.
 
  In 1995, Schein Holdings, Inc. ("SHI"), the former parent holding
corporation of the Company, was merged into the Company. The Company was the
only asset held then by SHI, and, as such, the accompanying financial
statements reflect the operations of the Company for the periods reported.
 
  The consolidated financial statements include the accounts of the Company
and its wholly-owned and majority-owned subsidiaries. Investments in
unconsolidated affiliated companies are accounted for on the equity method.
All material intercompany accounts and transactions have been eliminated in
consolidation.
 
  Certain prior year amounts have been reclassified to conform to the current
year's presentation.

  The Company reports its operations on a 52-53 week basis ending on the last
Saturday of December. Of the years presented in these statements, 1994
includes 53 weeks.
 
  Interim Financial Information
 
  The financial statements as of September 27, 1997 and for the nine months
ended September 28, 1996 and September 27, 1997 are unaudited but reflect all
adjustments (consisting only of normal recurring adjustments) which are, in
the opinion of management, necessary for a fair presentation of financial
position and results of operations. Operating results for the nine months
ended September 27, 1997 are not necessarily indicative of the results that
may be expected for the fiscal year ending December 27, 1997.
 
  Cash Equivalents
 
  The Company considers all highly liquid debt instruments and other short-
term investments with an initial maturity date of three months or less from
purchase date to be cash equivalents.
 
  Inventories
 
  Inventories are valued at the lower of cost or market. Cost is determined by
the first-in, first-out method.
 
  Property, Plant, Equipment, Depreciation and Amortization
 
  Property, plant and equipment are stated at cost. Depreciation and
amortization are computed primarily under the straight-line method over
estimated useful lives. Amortization of capital leases is computed using the
straight-line method over the lease term.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
      (INFORMATION AS OF SEPTEMBER 27, 1997 AND FOR THE NINE-MONTHS ENDED
            SEPTEMBER 28, 1996 AND SEPTEMBER 27, 1997 IS UNAUDITED)
 
  Long-Lived Assets
 
  The Company adopted in 1995 Statement of Financial Accounting Standards
("SFAS") No. 121, Accounting for Impairment of Long-Lived Assets and for Long-
Lived Assets to be Disposed of. In accordance with SFAS No. 121, the carrying
values of long-lived assets are periodically reviewed by the Company and
impairments would be recognized if the expected future operating non-
discounted cash flows derived from an asset were less than its carrying value.
 
  Deferred Loan Fees
 
  Costs incurred in connection with entering into or amending debt agreements
are capitalized to Other Assets and amortized to interest expense using the
effective interest method over the lives of the related debt.
 
  Goodwill and Product Rights, Licenses and Regulatory Approvals
 
  Goodwill is being amortized over 25 years on a straight-line basis. Product
rights, licenses and regulatory approvals are amortized on a straight-line
basis over the expected profitable and useful lives of the underlying products
and manufacturing facilities, generally for periods ranging from 10 to 20
years.
 
  Investments in Marketable Securities
 
  The Company's available-for-sale marketable securities are carried at fair
market value and are included in Other Assets in the accompanying balance
sheets. Unrealized gains are recorded directly to stockholders' equity, net of
applicable income taxes. The Company uses the specific identification method
of determining cost in calculating related gains and losses. The Company does
not own held-to-maturity or trading securities.
 
  Estimated Fair Value of Financial Instruments
 
  The carrying amounts of financial instruments, including cash and cash
equivalents, accounts receivable, accounts payable and accrued liabilities,
approximate fair value because of the current nature of these instruments. The
carrying amounts reported for revolving credit and long-term debt approximate
fair value because the interest rates on these instruments are subject to
changes with market interest rates.
 
  Revenue Recognition
 
  Revenues are recognized when products are shipped. Provisions for estimated
sales allowances, returns and losses are accrued at the time revenues are
recognized.
 
  Research and Development Expenditures
 
  Expenditures for research and development are expensed as incurred.
 
  Taxes on Income
 
  The Company accounts for income taxes in accordance with SFAS No. 109,
Accounting for Income Taxes. Under this standard, deferred taxes on income are
provided for those items for which the reporting period and methods for income
tax purposes differ from those used for financial statement purposes using the
asset and liability method. Deferred income taxes are recognized for the tax
consequences of "temporary differences" by applying enacted statutory rates
applicable to future years to differences between the financial statement
carrying amounts and the tax bases of existing assets and liabilities.

  Foreign Currency Translations
 
  Assets and liabilities of international affiliates are translated at current
exchange rates and related translation adjustments are reported as a component
of stockholders' equity. Income statement accounts are translated at the
average rates during the period.
 
  Concentration of Credit Risk
 
  The Company is potentially subject to a concentration of credit risk with
respect to its trade receivables, the majority of which are due from
wholesalers, drug store chains and distributors. The Company performs ongoing
credit evaluations of its customers and generally does not require collateral.
The Company maintains sufficient allowances and insurance to cover potential
or anticipated losses for uncollectible accounts.
 
  Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires the Company to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Effect of Recently Issued Accounting Standards
 
  In June 1997, the Financial Accounting Standards Board issued two new
disclosure standards.
 
  Statement of Financial Accounting Standards No. 130 ("SFAS No. 130"),
Reporting Comprehensive Income, establishes standards for reporting and
display of comprehensive income, its components and accumulated balances.
Comprehensive income is defined to include all changes in equity except those
resulting from investments by owners and distributions to owners. Among other
disclosures, SFAS No. 130 requires that all items that are required to be
recognized under current accounting standards as components of comprehensive
income be reported in a financial statement that is displayed with the same
prominence as other financial statements.
 
  Statement of Financial Accounting Standards No. 131 ("SFAS No. 131"),
Disclosures about Segments of an Enterprise and Related Information, which
supersedes SFAS No. 14, Financial Reporting for Segments of a Business
Enterprise, establishes standards for the way that public enterprises report
information about operating segments in annual financial statements and
requires reporting of selected information about operating segments in interim
financial statements issued to the public. It also establishes standards for
disclosures regarding products and services, geographic areas and major
customers. SFAS No. 131 defines operating segments as components of an
enterprise about which separate financial information is available that is
evaluated regularly by the chief operating decision maker in deciding how to
allocate resources and in asserting performance.
 
  Both of these new standards are effective for financial statements for
periods beginning after December 15, 1997 and require comparative information
for earlier years to be restated. Results of operations and financial position
will be unaffected by implementation of these new standards.The Company,
however, has not determined whether either of these two standards will have a
material impact on its financial statement disclosure.

NOTE 2--RESTRUCTURING
 
  As discussed in Note 1, SHI, the former parent corporation of the Company,
was merged into the Company in 1995. Prior to September 1994, in addition to
its ownership of the Company, SHI was engaged in the manufacture, distribution
and sale of dental, medical and veterinary products ("Henry Schein"). In 1992,
SHI initiated a series of transactions as part of a corporate reorganization
plan (the "Restructuring") to split off Henry Schein to certain SHI
stockholders and realign the ownership interests of SHI. In September 1994,
the series of transactions culminated when the capital stock of Henry Schein
was distributed to individuals (and certain trusts established by them) who
were holders (or beneficiaries of trusts and estates which were holders) of
SHI's common stock prior to September 30, 1994 ("Historical SHI
Stockholders").
 
  The transactions related to the Restructuring were initiated in December
1992 when SHI contributed the net assets of Henry Schein to a newly formed
company which was owned by SHI. Schein Pharmaceutical, Inc. and Henry Schein
both issued common stock to their respective chief executive officers
("CEOs"), which were forfeitable if certain conditions were not satisfied, and
paid cash bonuses to reimburse them for the personal income tax effects of the
stock issuance and reimbursements. SHI subsequently issued shares of its
common stock in exchange for the Schein Pharmaceutical, Inc. stock issuance
and these shares were reflected in the 1992 financial statements.
 
  The Restructuring continued in 1993, when Historical SHI Stockholders and
Company management agreed to a transaction whereby an investor would purchase
a portion of SHI's outstanding shares from Historical SHI Stockholders and
seek future strategic alliances (the "Minority Investor Transaction").
Following governmental regulatory review and Surrogate Court approval, the
closing occurred on September 30, 1994. The Restructuring transactions
recorded in 1994 are as follows:
 
    (i) SHI distributed the shares of Henry Schein to the Historical SHI
  Stockholders.
 
    (ii) SHI issued 854,235 shares of its common stock in exchange for the
  minority interest-redeemable stock in Schein Pharmaceutical, Inc.'s
  subsidiaries. The $13.2 million fair value of the shares issued exceeded
  the minority interest previously recorded by $7.3 million. Of this amount,
  $5.5 million was classified as special compensation expense in 1994 (for
  Schein Pharmaceutical, Inc. employees) and $1.8 million was recorded as a
  distribution by the Company to Henry Schein (for the CEO of Henry Schein).
 
    (iii) As a result of the Minority Investor Transaction described above,
  the shares of common stock issued to the CEOs of the Company and Henry
  Schein became free of the forfeiture provisions. Accordingly, the shares
  were revalued using the September 30, 1994 fair value. The amounts relating
  to (1) the Company's CEO totaled $18.6 million and was recorded as special
  compensation expense, and (2) Henry Schein's CEO totaled $5.7 million, and
  the excess of that amount over the 1992 fair value totaled $3.1 million,
  which was recorded as a capital distribution.
 
    (iv) SHI retained the services of investment banking and financial
  advisory firms. Of the fees paid to these firms, $1.5 million was charged
  to retained earnings, as such amount related to the Minority Investor
  Transaction.
 
    (v) SHI redeemed its outstanding preferred stock for $25.7 million,
  paying $20.7 million in cash and canceling a $5.0 million loan to a
  preferred stockholder.
 
    (vi) SHI established a supplemental retirement program for its CEO and
  recognized as current expense the Company's obligation under the plan,
  estimated at $5.0 million. This liability is included in Other Liabilities
  in the accompanying balance sheets.
 
  Professional fees incurred by the Company of $4.2 million in 1994 in
connection with the Restructuring were recorded as restructuring expense.

NOTE 3--ACQUISITIONS AND INVESTMENTS IN INTERNATIONAL AFFILIATES
 
  The Company acquired all the outstanding capital stock of Marsam
Pharmaceuticals Inc. ("Marsam") in September 1995 for $245.0 million in cash.
Marsam develops, manufactures and markets generic injectable prescription
drugs. The acquisition was accounted for as a purchase. The purchase price of
$245.0 million exceeded the book value of the net assets acquired by $193.0
million. Of the excess purchase price, $92.0 million was allocated to increase
the net assets acquired to fair value, principally related to regulatory
facility and product approvals and is being amortized over 15 years. Acquired
in-process Marsam research and development projects were valued at $30.0
million and were expensed at the time of the acquisition. Goodwill of $108.0
million, consisting of the remaining excess purchase price of $71.0 million
and a $37.0 million deferred tax liability resulting from the write-up of the
net assets to fair value is being amortized over 25 years. Marsam's results of
operations have been included in the consolidated statements of operations
since the date of acquisition.
 
  The following summarized, unaudited pro forma results of operations for 1994
and 1995 assume the acquisition occurred as of the beginning of 1994. In
preparing the pro forma data, adjustments have been made for the amortization
of goodwill and other intangibles acquired, the interest expense related to
borrowing agreements to finance the purchase price and, in 1994 only, the
write-off of acquired in-process Marsam research and development projects.
Since the valuation of Marsam's net assets and in-process research and
development projects may have differed at January 1, 1994 from amounts
recorded at September 1, 1995, the information presented is not necessarily
indicative of results of operations that would have occurred had the
acquisition been consummated at the beginning of the respective periods, or of
future results of the combined companies.

  During 1995 and 1996, the Company invested approximately $3.5 million and
$2.0, respectively, to acquire up to a 50% interest in each of several
international pharmaceutical businesses. These businesses are jointly owned
with subsidiaries of Bayer AG, the parent of Bayer Corp., a minority investor
in the Company. These investments are accounted for under the equity method
and are included in Other Assets in the accompanying balance sheets. Equity
losses resulting from the Company's investments in international businesses in
1995, 1996 and the nine months ended September 28, 1996 and September 27, 1997
are included in Other expenses (income), net, in the accompanying statements
of operations. The Company generally anticipates that these international
businesses will not have significant revenues or operations for a period of
two to three years following their establishment, during which time the
businesses are expected to incur expenses to register products in anticipation
of future sales.

  The Company has a tax grant in Puerto Rico. The grant provides a 90%
exclusion from Puerto Rico income tax. The grant began in 1996 and expires in
15 years. The grant benefits are recognized in conjunction with the Company's
election to compute its US tax under Internal Revenue Code Section 936 which
reduces the tax by an amount based on the Company's operations. The 936 credit
reduced the US tax in 1996 by $0.5 million.

  In September 1995, the Company entered into a secured revolving credit and
term loan agreement (as amended, the "credit agreement") with a group of banks
to provide funds for the acquisition of Marsam, the repayment of certain of
its debt, working capital and general corporate purposes. The credit agreement
provided a term loan facility of $250.0 million and a revolving credit
facility of $100.0 million available through December 2001. Amounts borrowed
under the revolving credit facility are expected to be repaid during the next
year and, accordingly, are classified as current in the accompanying balance
sheets. The borrowings outstanding under the revolving credit facility were
$30.0 million, $41.0 million and $26.0 million as of December 30, 1995,
December 28, 1996 and September 27, 1997, respectively. Quarterly principal
payments on the term loan commence in September 1998 and end in the year 2001.
 
  In December 1996, the Company entered into an agreement for a $100.0 million
senior subordinated loan with a lead manager of the credit agreement.
Outstanding borrowings under the senior subordinated loan agreement bear
interest, payable quarterly, at a rate equal to LIBOR plus 4% or the bank's
floating base rate plus 3%, through January 31, 1998. Thereafter, the
principal amount of the loan will be increased to reflect related fees due and
will mature in five years. Interest will be due semi-annually and the interest
rate will be fixed at a new rate. The proceeds of the loan were used to prepay
principal on the term loan of the credit agreement. The effective borrowing
rate of the senior subordinated loan was 9.60% as of December 28, 1996. As a
result of this payment and scheduled payments, the term loan facility was
reduced to $130.0 million at September 1997. See Note 19--Subsequent Events.
 
  Borrowings under the credit agreement bear interest, which is payable at
least quarterly, at a rate equal to the bank's floating base rate plus a
premium ranging from zero to 1.50%, or at a rate equal to LIBOR plus a premium
ranging from 0.75% to 2.50%, depending on the type of borrowing and the
Company's performance against certain criteria. The effective borrowing rate
was 7.14%, 8.10% and $7.80% at December 30, 1995, December 28, 1996 and
September 27, 1997, respectively. A commitment fee ranging from 0.25% to 0.50%
per annum of the unused daily amount of the total commitment is payable
quarterly.
 
  Borrowings under the credit agreement are secured by a mortgage on all real
property, liens on inventory and receivables and a pledge of subsidiaries'
stock. The debt is guaranteed by the Company's domestic subsidiaries.
 
  The credit agreement contains limitations and restrictions concerning
investments, acquisitions, capital expenditures, debt, liens, transactions
with stockholders, dividend payments and borrowings. In addition, the
agreement requires the Company to maintain minimum net worth levels and
certain ratios (as defined therein) of leverage to EBITDA, working capital and
fixed charge coverage. Amounts available for dividends as permitted by the
credit agreement as of September 27, 1997 were not material.

  In connection with entering into the credit agreement, the Company incurred
costs of $5.9 million in 1995. During 1996, the Company incurred costs of $2.3
million in connection with entering into the senior subordinated loan and
amending the credit agreement. The Company capitalized these costs, which are
included in Other Assets in the accompanying balance sheets. The amounts
amortized in 1995 and 1996 were $0.7 million and $2.6 million, respectively.
 
  At December 28, 1996, aggregate required principal payments for the
succeeding four years, the remaining term under existing long-term debt
agreements, excluding the revolving credit facility, are $15.3 million in
1998, $38.2 million in 1999, $45.7 million in 2000 and $45.8 million in 2001.

COMMITMENTS
 
 Consulting Agreement
 
  The Company has a series of agreements (collectively, the "Consulting
Agreement") with a patent attorney (the "Consultant"). The Consulting
Agreement generally provides that if a challenge based on an opinion of the
Consultant results in either a favorable judicial determination which enables
the Company to market a generic version of the product or in a settlement, the
Company will pay the Consultant one half of the adjusted gross profit (as
defined) from its sales of the generic versions of the patented product (until
the date on which the patent would normally have expired) or one half of the
proceeds of any settlement. Under the Consulting Agreement, the Consultant,
together with the Company, has identified certain patents on branded
pharmaceutical products susceptible to a challenge and the Consultant acted as
counsel to the Company in those instances where it decided to proceed with a
patent challenge.
 
 
  In 1994, the Company settled two such patent challenges. One of the
settlements involved a license grant to the Company to begin manufacturing and
marketing the product in 1996. The second settlement allows for cash payments
and/or license rights to the Company. In connection with the second
settlement, the Company received revenues of $5.0 million and $12.5 million in
1995 and 1996, respectively, and, such amounts are included in Net revenues in
the accompanying statements of operations.
 
  Profit-sharing expenses pursuant to the Consulting Agreement and included in
Cost of sales were $2.5 million in fiscal 1995 and $14.9 million in fiscal
1996.
 
 Operating Leases
 
  The Company leases facilities and equipment under operating leases expiring
through 2007. Some of the leases have renewal options and most contain
provisions for passing through certain incremental costs. At December 28,
1996, future net minimum annual rental payments under noncancelable leases are

  Total rental expense for the years ended 1994, 1995 and 1996 was
approximately $3.7 million, $4.7 million and $5.4 million, respectively.
 
  The Company has an agreement to lease warehousing space through September
1999, and then purchase this property for $5.3 million in October 1999. In
1998 the Company intends to exercise its option to purchase this property. The
property consists of a building of approximately 109,800 square feet on
approximately 8.5 acres of land. The purchase price includes a $0.3 million
deposit paid in 1994.
 
 Employee Benefit Plans
 
  During 1996, the Company merged its defined contribution retirement plans
into one plan. The discretionary contributions to the plan vest to employees
over several years. Additionally, employees are permitted to make pre-tax
contributions to the plan with the Company making matching contributions. The
contributions to these plans which were charged to operations, as determined
by the Board of Directors, amounted to approximately $4.2 million, $4.9
million and $3.5 million for the years ended 1994, 1995 and 1996,
respectively.
 
  The Company has entered into deferred compensation agreements with certain
officers of the Company. As of December 1996, future obligations under these
agreements were approximately $6.6 million, assuming the officers remain with
the Company over the remaining vesting period of one to three years. These
agreements provide for accelerated vesting if there is a change in control of
the Company under certain other conditions. The Company expensed $2.7 million,
$2.0 million and $4.8 million in the fiscal years ended 1994, 1995 and 1996,
respectively, in connection with these agreements.
 
  The Company established an unfunded supplemental retirement program for its
CEO during 1994. The estimated obligation of $5.0 million is included in Other
Liabilities in the accompanying balance sheets.
 
  The Company maintains a Book Equity Appreciation Rights Program (the
"Program") to allow certain employees to benefit from an increase in the
Company's book value as calculated according to a formula defined in the
Program. All participants are fully vested in their book equity appreciation
rights ("BEARs") and the Company does not intend to make any additional grants
of BEARs. Amounts charged to results of operations were not material in any
period presented.
 
 Product Technology Licensing and Development
 
  On September 1, 1994, the Company entered into a worldwide technology
licensing and development agreement with a U.K.-based pharmaceutical
development company for the development of a portfolio of oral controlled
release and/or transdermal products. Under the terms of the agreement, the
Company is obligated to pay product licensing fees and development costs
totaling $32.0 million, dependent on achievement of interim milestones. In
1994, the Company incurred obligations totaling $5.5 million under the
agreement, consisting of a $5.0 million licensing fee, which was capitalized.
The Company paid and expensed $2.4 million in development costs in 1995. In
1996, the Company incurred obligations totaling $3.0 million, consisting of a
$0.5 million licensing fee, which was capitalized, and $2.5 million in
development costs which were charged to research and development expense. The
remaining commitment under the agreement as of December 28, 1996 was $21.1
million, subject to the completion of interim milestones.
 
  On September 30, 1996, the Company entered into a marketing and distribution
agreement with a corporation to jointly commercialize a certain product. Under
the terms of the agreement, the Company is obligated to pay product licensing
fees and development costs of $12.0 million, dependent on the achievement of
certain milestones. In 1996, the Company paid and capitalized a $2.0 million
product license fee.

CONTINGENCIES
 
 Litigation
 
  The Company is a defendant in several product liability cases. These cases
are typical for a company in the pharmaceutical industry. The Company also is
involved in other proceedings and claims of various types. Management
presently believes that the disposition of all such known proceedings and
claims, individually or in the aggregate, will not have a material adverse
effect on the Company's financial position, operations or liquidity.
 
NOTE 12--STOCKHOLDERS' EQUITY AND STOCK OPTIONS
 
  Common Stock
 
  The Company has Class A Common Shares ("Class A") and Class B Common Shares
("Class B"). Each of the two classes of stock are identical except that Class
B shares are currently non-voting. Upon the earlier occurrence of an initial
public offering or May 15, 1999, each authorized share of Class B will be
automatically reclassified as and converted into one new Class A share.
 
  Upon the closing of the Company's planned initial public offering, the Class
A and Class B will convert on a one-for-one basis to new shares of the
Company's common stock.
 
  At December 30, 1995 and December 28, 1996, the Company had 22,597,806 and
22,539,012 Class A issued and outstanding, respectively. The Company had
11,072,460 Class B issued and outstanding for all periods presented.
 
  During 1996, the Company agreed to repurchase 58,794 Class A for
approximately $1.0 million from a former executive of the Company. These
shares were retired in 1996.
 
  Stock Option Plan
 
  In October 1995, the Financial Accounting Standards Board issued SFAS No.
123, Accounting for Stock- Based Compensation. SFAS No. 123 encourages
entities to adopt that method in place of the provisions of Accounting
Principles Board Opinion Number 25, Accounting for Stock Issued to Employees
("APB No. 25"), for all arrangements under which employees receive shares of
stock or other equity instruments of the employer or the employer incurs
liabilities to employees in amounts based on the price of its stock. The
Company continues to account for such transactions in accordance with APB No.
25 and, as required by SFAS No. 123, has provided pro forma information
regarding net income as if compensation cost for the Company's stock option
plan had been determined in accordance with the fair value method prescribed
by SFAS No. 123.
 
  Under the Company's 1993 Stock Option Plan, 1995 Non-Employee Director Stock
Option Plan and effective March 3, 1997, a 1997 Stock Option Plan the Company
may grant non-qualified and incentive stock options to certain officers,
employees and directors. The options expire ten years from the grant date. The
options may be exercised subject to continued service (three to five years)
and certain other conditions. Accelerated vesting occurs following a change in
control of the Company and under certain other conditions. The Company may
grant an aggregate of 6,863,400 shares under the plans. However, 261,006
shares under the 1993 Stock Option Plan will not be granted.
 
  The Company estimates the fair value of each stock option at the grant date
by using the Black-Scholes option-pricing model with the following weighted
average assumptions used for grants in 1995 and 1996: no dividend yield,
expected volatility of 0.01%, risk free interest rates of 5% to 7%, expected
lives of 10 years and

a discount for marketability of 25%. If compensation cost for the Company's
stock option plan had been determined in accordance with SFAS No. 123, net
income (loss) would have been reduced in 1995 and 1996 by approximately $1.0
million and $2.3 million, respectively.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Article SEVENTH of the Company's Certificate of Incorporation provides that
the Company shall indemnify and hold harmless, to the fullest extent
authorized by the Delaware General Corporation Law, its officers and directors
against all expenses, liability and loss actually and reasonably incurred in
connection with any civil, criminal, administrative or investigative action,
suit or proceeding. The Certificate of Incorporation also extends
indemnification to those serving at the request of the Company as directors,
officers, employees or agents of other enterprises.
 
  In addition, Article SEVENTH of the Company's Certificate of Incorporation
provides that no director shall be personally liable for any breach of
fiduciary duty. Article SEVENTH does not eliminate a director's liability (i)
for a breach of his or her duty of loyalty to the Company or its stockholders,
(ii) for acts of or omissions of such director not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law, or (iv) for any
transactions from which the director derived an improper personal benefit.
 
  Section 145 of the General Corporation Law of the State of Delaware permits
a corporation to indemnify its directors and officers against expenses
(including attorney's fees), judgments, fines and amounts paid in settlements
actually and reasonably incurred by them in connection with any action, suit
or proceeding brought by third parties, if such directors or officers acted in
good faith and in a manner they reasonably believed to be in or not opposed to
the best interests of the corporation and, with respect to any criminal action
or proceeding, had no reason to believe their conduct was unlawful. In a
derivative action, i.e., one by or in the right of the corporation,
indemnification may be made only for expenses actually and reasonably incurred
by directors and officers in connection with the defense or settlement of an
action or suit, and only with respect to a matter as to which they shall have
acted in good faith and in a manner they reasonably believed to be in or not
opposed to the best interest of the corporation, except that no
indemnification shall be made if such person shall have been adjudged liable
to the corporation, unless and only to the extent that the court in which the
action or suit was brought shall determine upon application that the defendant
officers or directors are reasonably entitled to indemnity for such expenses
despite such adjudication of liability.
 
  Section 102(b)(7) of the General Corporation Law of the State of Delaware
provides that a corporation may eliminate or limit the personal liability of a
director to the corporation or its stockholders for monetary damages for
breach of fiduciary duty as a director, provided that such provision shall not
eliminate or limit the liability of a director (i) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or
a knowing violation of law, (iii) under Section 174 of the General Corporation
Law of the State of Delaware, or (iv) for any transaction from which the
director derived an improper personal benefit. No such provision shall
eliminate or limit the liability of a director for any act or omission
occurring prior to the date when such provision becomes effective.
 
  Pursuant to Section 145 of the DGCL and the Certificate of Incorporation and
the By-Laws of the Company, the Company maintains directors' and officers'
liability insurance coverage.

ITEM 22. UNDERTAKINGS.
 
  The Registrant hereby undertakes:
 
    (a) To file, during any period in which offerings or sales are being
  made, a post-effective amendment to this registration statement:
 
      (i) To include any prospectus required by section 10(a)(3) of the
    Securities Act of 1933;
 
      (ii) To reflect in the prospectus any facts or events arising after
    the effective date of the registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the registration statement; and
 
      (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the registration statement or
    any material change to such information in the registration statement;
 
    (b) That, for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.
 
    (c) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.
 
    (d) That prior to any public reoffering of the securities registered
  hereunder through use of a prospectus which is a part of this registration
  statement, by any person or party who is deemed to be an underwriter within
  the meaning of Rule 145(c), the issuer undertakes that such reoffering
  prospectus will contain the information called for by the applicable
  registration form with respect to reofferings by persons who may be deemed
  underwriters, in addition to the information called for by the other Items
  of the applicable form.
 
    (e) That every prospectus (i) that is filed pursuant to paragraph (d)
  immediately preceding, or (ii) that purports to meet the requirements of
  section 10(a)(3) of the Securities Act of 1933 and is used in connection
  with an offering of securities subject to Rule 415 (Section 230.415 of this
  chapter), will be filed as a part of an amendment to the registration
  statement and will not be used until such amendment is effective, and that,
  for purposes of determining any liability under the Securities Act of 1933,
  each such post-effective amendment shall be deemed to be a new registration
  statement relating to the securities offered therein, and the offering of
  such securities at that time shall be deemed to be the initial bona fide
  offering thereof.
 
    (f) That, for purposes of determining any liability under the Securities
  Act of 1933, each filing of the registrant's annual report pursuant to
  Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that
  is incorporated by reference in the registration statement shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.
 
    (g) Insofar as indemnification for liabilities arising under the
  Securities Act of 1933 may be permitted to directors, officers and
  controlling persons of the registrant pursuant to the provisions described
  in Item 15, or otherwise, the registrant has been advised that in the
  opinion of the Securities and Exchange Commission such indemnification is
  against public policy as expressed in the Securities Act of 1933 and is,
  therefore, unenforceable. In the event that a claim for indemnification
  against such liabilities (other than the payment by the registrant of
  expenses incurred or paid by a director, officer or controlling person of
  the registrant in
 
                                     II-5
<PAGE>
 
  the successful defense of any action, suit or proceeding) is asserted by
  such director, officer or controlling person in connection with the
  securities being registered, the registrant will, unless in the opinion of
  its counsel the matter has been settled by controlling precedent, submit to
  a court of appropriate jurisdiction the question whether such
  indemnification by it is against public policy as expressed in the
  Securities Act of 1933 and will be governed by the final adjudication of
  such issue.
 
    (h) To respond to requests for information that is incorporated by
  reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of Form
  S-4, within one business day of receipt of such request, and to send the
  incorporated documents by first class mail or other equally prompt means.
  This includes information contained in documents filed subsequent to the
  effective date of the registration statement through the date of responding
  to the request.
 
    (i) To supply by means of post-effective amendment all information
  concerning a transaction, and the company being acquired involved therein,
  that was not the subject of and included in the registration statement when
  it became effective.

(including heirs, executors, administrators and other personal representatives
of such person) against expenses including attorneys' fees, judgments, fines and
amounts paid in settlement, actually and reasonably incurred by such person in 
connection with any threatened, pending or completed suit, action or proceeding 
(whether civil, criminal, administrative or investigative in nature or 
otherwise) in which such person may be involved by reason of the fact that he or
she is or was a director or officer of the corporation or is or was serving any 
other incorporated or unincorporated enterprise in such capacity at the request 
of the corporation.

director shall be elected to serve until his or her successor shall be elected 
and shall qualify. Directors need not be stockholders.

        SECTION 2.  RESIGNATIONS.--Any director, member of a committee or other 
officer may resign at any time. Such resignation shall be made in writing, and 
shall take effect at the time specified therein, and if no time be specified, at
the time of its receipt by the President or Secretary. The acceptance of a 
resignation shall not be necessary to make it effective.

        SECTION 3.  VACANCIES.--If the office of any director, member of a 
committee or other officer becomes vacant, the remaining directors in office, 
though less than a quorum by a majority vote, may appoint any qualified person 
to fill such vacancy, who shall hold office for the unexpired term and until his
successor shall be duly chosen provided, however, that if there are no directors
then in office due to such a vacancy, the stockholders may elect a successor 
who shall hold office for the unexpired term and until his successor shall be 
elected and qualified.

        SECTION 4. REMOVAL.--Except as hereinafter provided, any director or 
directors may be removed either for or 

                                       3
<PAGE>
 
without cause at any time by the affirmative vote of the holders of a majority 
of all the shares of stock outstanding and entitled to vote, at a special 
meeting of the stockholders called for the purpose and the vacancies thus 
created may be filled, at the meeting held for the purpose of removal, by the 
affirmative vote of a majority in interest of the stockholders entitled to vote.

        Unless the Certificate of Incorporation otherwise provides, stockholders
may effect removal of a director who is a member of a classified Board of
Directors only for cause. If the Certificate of Incorporation provides for
cumulative voting and if less than the entire board is to be removed, no
director may be removed without cause if the votes cast against his removal
would be sufficient to elect him if then cumulatively voted at an election of
the entire board of directors, or, if there be classes of directors, at an
election of the class of directors of which he is a part.

        If the holders of any class or series are entitled to elect one or more 
directors by the provisions of the Certificate of Incorporation, these 
provisions shall apply, in respect to the removal without cause of a director or
directors so elected, to the vote of the holders of the outstanding shares of 
that class or series and not to the vote of the outstanding shares as a whole.

        SECTION 5.  INCREASE OF NUMBER.--The number of directors may be 
increased by the affirmative vote of a majority of the directors, though less 
than a quorum, or, by the affirmative vote of a majority in interest of the 
stockholders, at the annual meeting or at a special meeting called for that 
purpose, and by like vote the additional directors may be chosen at such meeting
to hold office until the next annual election and until their successors are 
elected and qualify.

        SECTION 6.  POWERS.--The Board of Directors shall exercise all powers of
the corporation except such as are by law, or by the Certificate of 
Incorporation of the corporation or by these By-Laws conferred upon or reserved 
to the stockholders.

        SECTION 7.  COMMITTEES.--The Board of Directors may, by resolution or 
resolutions passed by a majority of the whole board, designate one or more 
committees, each committee to consist of one or more of the directors of the
corporation. The board may designate one or more directors as alternate members
of any committee, who may replace any absent or disqualified member at any
meeting of the committee. In the absence or disqualification of any member of
such committee or committees, the member or members thereof present at any
meeting and not disqualified from voting, whether or not he or they constitute a
quorum, may unanimously appoint another member of the Board of

                                       4
<PAGE>
 
Directors to act at the meeting in the place of any such absent or disqualified 
member.

        Any such committee, to the extent provided in the resolution of the 
Board of Directors, or in these By-Laws, shall have and may exercise all the 
powers and authority of the Board of Directors in the management of the business
and affairs of the corporation, and may authorize the seal of the corporation to
be affixed to all papers which may require it; but no such committee shall have 
the power or authority in reference to amending the Certificate of 
Incorporation, adopting an agreement of merger or consolidation, recommending to
the stockholders the sale, lease or exchange of all or substantially all of the 
corporation's property and assets, recommending to the stockholders a 
dissolution of the corporation or a revocation of a dissolution, or amending the
By-Laws of the corporation; and, unless the resolution, these By-Laws or the 
Certificate of Incorporation expressly so provide, no such committee shall have 
the power or authority to declare a dividend or to authorize the issuance of 
stock.

        SECTION 8.  MEETINGS.--The newly elected directors may hold their first 
meeting for the purpose of organization and the transaction of business, if a 
quorum be present, immediately after the annual meeting of the stockholders; or 
the time and place of such meeting may be fixed by consent in writing of all the
directors.

        Regular meetings of the directors may be held without notice at such 
places and times as shall be determined from time to time by resolution of the 
directors.

        Special meetings of the board may be called by the President or by the 
Secretary on the written request of any two directors on at least two days' 
notice to each director and shall be held at such place or places as may be 
determined by the directors, or as shall be stated in the call of the meeting.

        Unless otherwise restricted by the Certificate of Incorporation or these
By-Laws, members of the Board of Directors, or any committee designated by the 
Board of Directors, may participate in a meeting of the Board of Directors, or 
any committee, by means of conference telephone or similar communications 
equipment by means of which all persons participating in the meeting can hear 
each other, and such participation in a meeting shall constitute presence in 
person at the meeting.

        SECTION 9.  QUORUM.--A majority of the directors shall constitute a 
quorum for the transaction of business. If at any meeting of the board there 
shall be less than a quorum present, a majority of those present may adjourn the
meeting from time to time until a quorum is obtained, and no 

                                       5
<PAGE>
 
further notice thereof need be given other than by announcement at the meeting 
which shall be so adjourned.

        SECTION 10.     COMPENSATION. -- Directors shall not receive any stated 
salary for their services as directors or as members of committees, but by 
resolution of the board a fixed fee and expenses of attendance may be allowed 
for attendance at each meeting.  Nothing herein contained shall be construed to 
preclude any director from serving the corporation in any other capacity as an 
officer, agent or otherwise, and receiving compensation therefor.

        SECTION 11.     ACTION WITHOUT MEETING. -- Any action required or 
permitted to be taken at any meeting of the Board of Directors, or of any 
committee thereof, may be taken without a meeting, if a written consent thereto
is signed by all members of the board, or of such committee as the case may be, 
and such written consent id filed with the minutes of proceedings of the board 
or committee.

        SIXTH:    Whenever a compromise or arrangement is proposed between this 
corporation and its creditors or any class of them and/or between this 
corporation and its stockholders or any class of them, any court of equitable 
jurisdiction within the State of Delaware may, on the application in a summary 
way of this corporation or of any creditor or stockholder thereof or on the 
application of any receiver or receivers appointed for this corporation under 
the provisions of (S)291 of Title 8 of the Delaware Code or on the application 
of trustees in dissolution or of any receiver or receivers appointed for this 
corporation under the provisions of (S)279 of Title 8 of the Delaware Code order

(including the heirs, executors, administrators and other personal
representatives of such person) against expenses including attorneys' fees,
judgments, fines and amounts paid in settlement, actually and reasonably
incurred by such person in connection with any threatened, pending or completed
suit, action or proceeding (whether civil, criminal, administrative or
investigative in nature or otherwise) in which such person may be involved by
reason of the fact that he or she is or was a director or officer of the
corporation or is or was serving any other incorporated or unincorporated
enterprise in such capacity at the request of the corporation.

        NINTH:    Unless, and except to the extent that, the by-laws of the

          SECTION 7. ACTION WITHOUT MEETING.--Unless otherwise provided by the

shall be signed by the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and
voted. Prompt notice of the taking of the corporate action without a meeting by
less than unanimous written consent shall be given to those stockholders who
have not consented in writing.


                                  ARTICLE III

                                   DIRECTORS

          SECTION 1. NUMBER AND TERM.--The number of directors constituting the
Board of Directors shall be not more than nine nor less than one, as fixed from
time to time by action of the stockholders or the Board of Directors. The
directors shall be elected at the annual meeting of the stockholders and each
director shall be elected to serve until his or her successor shall be elected
and shall qualify. Directors need not be stockholders.

          SECTION 2. RESIGNATIONS.--Any director, member of a committee or other
officer may resign at any time. Such resignation shall be made in writing, and
shall take effect at the time specified therein, and if no time be specified, at
the time of its receipt by the President or Secretary. The acceptance of a
resignation shall not be necessary to make it effective.

          SECTION 3. VACANCIES.--If the office of any director, member of a
committee or other officer becomes vacant, the remaining directors in office,
though less than a quorum by a majority vote, may appoint any qualified person
to fill such vacancy, who shall hold office for the unexpired term and until his
successor shall be duly chosen provided, however, that if there are no directors
then in office due to such a vacancy, the stockholders may elect a successor who
shall hold office for the unexpired term and until his successor shall be
elected and qualified.

                 SECTION 4. REMOVAL.--Except as hereinafter provided, any
director or directors may be removed either for or

                                       3
<PAGE>
 
without cause at any time by the affirmative vote of the holders of a majority
of all the shares of stock outstanding and entitled to vote, at a special
meeting of the stockholders called for the purpose and the vacancies thus
created may be filled, at the meeting held for the purpose of removal, by the
affirmative vote of a majority in interest of the stockholders entitled to vote.

          Unless the Certificate of Incorporation otherwise provides,
stockholders may effect removal of a director who is a member of a classified
Board of Directors only for cause. If the Certificate of Incorporation provides
for cumulative voting and if less than the entire board is to be removed, no
director may be removed without cause if the votes cast against his removal
would be sufficient to elect him if then cumulatively voted at an election of
the entire board of directors, or, if there be classes of directors, at an
election of the class of directors of which he is a part.

          If the holders of any class or series are entitled to elect one or
more directors by the provisions of the Certificate of Incorporation, these
provisions shall apply, in respect to the removal without cause of a director or
directors so elected, to the vote of the holders of the outstanding shares of
that class or series and not to the vote of the outstanding shares as a whole.

          SECTION 5. INCREASE OF NUMBER.--The number of directors may be
increased by the affirmative vote of a majority of the directors, though less
than a quorum, or, by the affirmative vote of a majority in interest of the
stockholders, at the annual meeting or at a special meeting called for that
purpose, and by like vote the additional directors may be chosen at such meeting
to hold office until the next annual election and until their successors are
elected and qualify.

          SECTION 6. POWERS.--The Board of Directors shall exercise all of the
powers of the corporation except such as are by law, or by the Certificate of
Incorporation of the corporation or by these By-Laws conferred upon or reserved
to the stockholders.

          SECTION 7. COMMITTEES.--The Board of Directors may, by resolution or
resolutions passed by a majority of the whole board, designate one or more
committees, each committee to consist of one or more of the directors of the
corporation. The board may designate one or more directors as alternate members
of any committee, who may replace any absent or disqualified member at any
meeting of the committee. In the absence or disqualification of any member of
such committee or committees, the member or members thereof present at any
meeting and not disqualified from voting, whether or not he or they constitute a
quorum, may unanimously appoint another member of the Board of

                                       4
<PAGE>
 
Directors to act at the meeting in the place of any such absent or disqualified
member.

          Any such committee, to the extent provided in the resolution of the
Board of Directors, or in these By-Laws, shall have and may exercise all the
powers and authority of the Board of Directors in the management of the business
and affairs of the corporation, and may authorize the seal of the corporation to
be affixed to all papers which may require it; but no such committee shall have
the power or authority in reference to amending the Certificate of
Incorporation, adopting an agreement of merger or consolidation, recommending to
the stockholders the sale, lease or exchange of all or substantially all of the
corporation's property and assets, recommending to the stockholders a
dissolution of the corporation or a revocation of a dissolution, or amending the
By-Laws of the corporation; and, unless the resolution, these By-Laws or the
Certificate of Incorporation expressly so provide, no such committee shall have
the power or authority to declare a dividend or to authorize the issuance of
stock.

          SECTION 8. MEETINGS.--The newly elected directors may hold their first
meeting for the purpose of organization and the transaction of business, if a
quorum be present, immediately after the annual meeting of the stockholders; or
the time and place of such meeting may be fixed by consent in writing of all the
directors.

          Regular meetings of the directors may be held without notice at such
places and times as shall be determined from time to time by resolution of the
directors.

          Special meetings of the board may be called by the President or by the
Secretary on the written request of any two directors on at least two days'
notice to each director and shall be held at such place or places as may be
determined by the directors, or as shall be stated in the call of the meeting.

          Unless otherwise restricted by the Certificate of Incorporation or
these By-Laws, members of the Board of Directors, or any committee designated
by the Board of Directors, may participate in a meeting of the Board of
Directors, or any committee, by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and such participation in a meeting shall
constitute presence in person at the meeting.

          SECTION 9. QUORUM.--A majority of the directors shall constitute a
quorum for the transaction of business. If at any meeting of the board there
shall be less than a quorum present, a majority of those present may adjourn the
meeting from time to time until a quorum is obtained, and no

                                       5
<PAGE>
 
further notice thereof need be given other than by announcement at the meeting
which shall be so adjourned.

          SECTION 10. COMPENSATION.--Directors shall not receive any stated
salary for their services as directors or as members of committees, but by
resolution of the board a fixed fee and expenses of attendance may be allowed
for attendance at each meeting. Nothing herein contained shall be construed to
preclude any director from serving the corporation in any other capacity as an
officer, agent or otherwise, and receiving compensation therefor.

          SECTION 11. ACTION WITHOUT MEETING.--Any action required or permitted
to be taken at any meting of the Board of Directors, or of any committee
thereof, may be taken without a meeting, if a written consent thereto is signed
by all members of the board, or of such committee as the case may be, and such
written consent is filed with the minutes of proceedings of the board or
committee.

at a meeting at which all shares entitled to vote thereon were present and
voted. Prompt notice of the taking of the corporate action without a meeting by

                                  ARTICLE III

          SECTION 1. NUMBER AND TERM.--The number of directors constituting the
Board of Directors shall be not more than nine nor less than one, as fixed from
time to time by action of the stockholders or the Board of Directors. The

          SECTION 4. REMOVAL.--Except as hereinafter provided, any director or
directors may be removed either for or without cause at any time by the
affirmative vote of the holders of a majority of all the shares of stock
outstanding and entitled to vote, at a special meeting of the stockholders
called for the purpose and the vacancies thus created may be filled, at the
meeting held for the purpose of removal, by the affirmative vote of a majority
in interest of the stockholders entitled to vote.

          Unless the Certificate of Incorporation a otherwise provides,
stockholders may effect removal of a director who is a member of a classified
Board of Directors only for cause. If the Certificate of Incorporation provides
for cumulative voting and if less than the entire board is to be removed, no
director may be removed without cause if the votes cast against his removal
would be sufficient to elect him if then cumulatively voted at an election of
the entire board of directors, or, if there be classes of directors, at an
election of the class of directors of which he is a part.

          If the holders of any class or series are entitled to elect one or
more directors by the provisions of the Certificate of Incorporation, these
provisions shall apply, in respect to the removal without cause of a director or
directors so elected, to the vote of the holders of the outstanding shares of
that class or series and not to the vote of the outstanding shares as a whole.

          SECTION 5. INCREASE OF NUMBER.--The number of directors may be
increased by the affirmative vote of a majority of the directors, though less
than a quorum, or, by the affirmative vote of a majority in interest of the
stockholders, at the annual meeting or at a special meeting called for that
purpose, and by like vote the additional directors may be chosen at such meeting
to hold office until the next annual election and until their successors are
elected and qualify.

          SECTION 6. POWERS.--The Board of Directors shall exercise all of the
powers of the corporation except such as are by law, or by the Certificate of
Incorporation of the corporation or by these By-Laws conferred upon or reserved
to the stockholders.

          SECTION 7. COMMITTEES.--The Board of Directors may, by resolution or
resolutions passed by a majority of the whole board, designate one or more
committees, each committee to consist of one or more of the directors of the
corporation. The board may designate one or more directors as alternate members
of any committee, who may replace any absent or disqualified member at any
meeting of the committee. In the absence or disqualification of any member of
such committee or committees, the member or members thereof present at any
meeting and not disqualified from voting, whether or not he or they constitute a

                                       4
<PAGE>
 
quorum, may unanimously appoint another member of the Board of Directors to act
at the meeting in the place of any such absent or disqualified member.

          Any such committee, to the extent provided in the resolution of the
Board of Directors, or in these By-Laws, shall have and may exercise all the
powers and authority of the Board of Directors in the management of the business
and affairs of the corporation, and may authorize the seal of the corporation to
be affixed to all papers which may require it; but no such committee shall have
the power or authority in reference to amending the Certificate of
Incorporation, adopting an agreement of merger or consolidation, recommending to
the stockholders the sale, lease or exchange of all or substantially all of the
corporation's property and assets, recommending to the stockholders a
dissolution of the corporation or a revocation of a dissolution, or amending the
By-Laws of the corporation; and, unless the resolution, these By-Laws or the
Certificate of Incorporation expressly so provide, no such committee shall have
the power or authority to declare a dividend or to authorize the issuance of
stock.

          SECTION 8. MEETINGS.--The newly elected directors may hold their first
meeting for the purpose of organization and the transaction of business, if a
quorum be present, immediately after the annual meeting of the stockholders; or
the time and place of such meeting may be fixed by consent in writing of all the
directors.

          Regular meetings of the directors may be held without notice at such
places and times as shall be determined from time to time by resolution of the
directors.

          Special meetings of the board may be called by the President or by the
Secretary on the written request of any two directors on at least two days'
notice to each director and shall be held at such place or places as may be
determined by the directors, or as shall be stated in the call of the meeting.

          Unless otherwise restricted by the Certificate of Incorporation or
these By-Laws, members of the Board of Directors, or any committee designated by
the Board of Directors, may participate in a meeting of the Board of Directors,
or any committee, by means of conference telephone or similar communications
equipment by means of which all persons participating in the meeting can hear
each other, and such participation in a meeting shall constitute presence in
person at the meeting.

          SECTION 9. QUORUM.--A majority of the directors shall constitute a
quorum for the transaction of business. If at any meeting of the board there
shall be less than a quorum present, a majority of those present may adjourn the

                                       5
<PAGE>
 
meeting from time to time until a quorum is obtained, and no further notice
thereof need be given other than by announcement at the meeting which shall be
so adjourned.

          SECTION 10. COMPENSATION.--Directors shall not receive any stated
salary for their services as directors or as members of committees, but by
resolution of the board a fixed fee and expenses of attendance may be allowed
for attendance at each meeting. Nothing herein contained shall be construed to
preclude any director from serving the corporation in any other capacity as an
officer, agent or otherwise, and receiving compensation therefor.

          SECTION 11. ACTION WITHOUT MEETING.--Any action required or permitted
to be taken at any meting of the Board of Directors, or of any committee
thereof, may be taken without a meeting, if a written consent thereto is signed
by all members of the board, or of such committee as the case may be, and such
written consent is filed with the minutes of proceedings of the board or
committee.

                                   ARTICLE IV

                    Pursuant to Section 151 of the General
                   Corporation Law of the State of Delaware


         The undersigned, Executive Vice President of STERIS LABORATORIES, INC.,
a Delaware corporation (the "Corporation"), certifies that the following
resolution was duly adopted by unanimous written consent of the Board of
Directors of the Corporation pursuant to authority conferred upon it by the
Certificate of Incorporation of the Corporation, as amended (the "Certificate of
Incorporation"):


             RESOLVED, that a series of the class of Preferred Stock $.01 par
         value, of the Corporation be created, and that the designations,
         powers, preferences and relative, participating, optional and other
         special rights thereof, and the qualifications, limitations or
         restrictions thereof, in addition to those set forth in the Certificate
         of Incorporation, and the number of shares of stock of such series, are
         as follows:

             1.  Designation and Number. The designation of the series of
                 ----------------------                                  
         Preferred Stock provided for herein shall be "Series A 10% Non-
         Cumulative Preferred Stock" (the "Series A Preferred Stock") and the
         number of shares constituting such series shall be 100.

             2.  Dividends. The holders of Series A Preferred Stock shall be
                 ---------                                                  
         entitled to receive, so long as the Series A Preferred Stock is
         outstanding, cash dividends equal to an aggregate of $2,500 per share
         per annum and no more, if, as and when declared by the Board of
         Directors, payable at such time or times as determined by the Board of
         Directors, out of funds at the time
<PAGE>
 
         legally available for the payment of dividends. Dividends on the Series
         A Preferred Stock shall be non-cumulative. No dividends (other than
         dividends payable in Preferred Stock of the Corporation ranking junior
         to the Series A Preferred Stock as to dividends and upon liquidation or
         in Common Stock) shall be declared, paid or set apart for payment on
         any other series of Preferred Stock ranking junior to the Series A
         Preferred Stock as to dividends or on Common Stock of the Corporation
         in any fiscal year of the Corporation unless and until dividends or on
         the Series A Preferred Stock in the amount of $2500 per share in such
         fiscal year shall have been paid or declared and a sum sufficient for
         the payment thereof set apart. If in any fiscal year a dividend is
         declared, paid or set apart on or in respect of the Series A Preferred
         Stock in an amount less than the aggregate annual amount per share the
         holders of the Series A Preferred Stock are entitled to receive, any
         dividend declared, paid or set apart on or in respect of any series of
         Preferred Stock of the Corporation ranking on a parity with the Series
         A Preferred Stock as to dividends shall be declared, paid or set apart
         ratably with the dividend declared, paid or set apart on or in respect
         of the Series A Preferred Stock, in accordance with the aggregate
         annual amounts per share payable on any such series, and on the Series
         A Preferred Stock.

              3.  Liquidation, Dissolution or Winding Up. In the event of any
                  ---------------------------------------                 
         liquidation, dissolution or winding up of the Corporation (whether
         voluntary or involuntary, and whether or not the Corporation shall have
         surplus or earnings available for dividends) before any payment or
         distribution of the assets of the Corporation (whether capital or
         surplus) shall be made to or set apart for the holders of any other
         series of Preferred Stock ranking junior to, or on a parity with, the
         Series A Preferred Stock upon liquidation, or of Common Stock, the
         holders of Series A Preferred Stock shall be entitled to receive
         payment of an amount equal to $25,000 per share and no more. If the
         assets of the Corporation, or the proceeds thereof, available for
         distribution to the holders of the Series A Preferred Stock and the
         holders of any other series of Preferred Stock on a parity with the
         Series A Preferred Stock upon liquidation shall be insufficient to pay
         in full all amounts to which the holders of Series A Preferred Stock
         and the holders of any such other series of

                                      -2-

         Preferred Stock are entitled, then such assets or the proceeds thereof
         shall be distributed among the holders of the Series A Preferred Stock
         and the holders of such other series of Preferred Stock ratably in
         accordance with the respective amounts which would be payable on such
         shares if all amounts payable were paid in full. For the purposes of
         this paragraph 3, the voluntary sale, lease, exchange or transfer (for

         Corporation with or into any other corporation shall not be deemed to
         be a liquidation, dissolution or winding up of the Corporation.

              4.  Redemption. The Corporation may, at its option, at any time or
                  ----------
         from time to time, redeem the whole or any part of the Series A
         Preferred Stock at a redemption price equal to $25,000 per share. In
         the event the Corporation shall determine to redeem less than all of
         the shares of the Series A Preferred Stock then outstanding, the Board
         of Directors shall determine the shares of Series A Preferred Stock so
         to be redeemed by lot or pro rata or by any other means which the Board
         of Directors deems equitable. Notice of any proposed redemption of any
         Series A Preferred Stock shall be given by the Corporation at least
         five (5) days prior to the date fixed for such redemption to the
         holders of record of the Series A Preferred Stock to be redeemed, at
         their respective addresses appearing on the books of the Corporation.
         If on the redemption date specified in such notice, the funds necessary
         for such redemption shall have been set aside by the Corporation,
         separate and apart from its other funds, in trust for the pro rata
         benefit of the holders of the shares so called for redemption, then,
         notwithstanding that any certificates for shares of Series A Preferred
         Stock so called for redemption shall not have been surrendered for
         cancellation, the shares represented thereby shall no longer be deemed
         outstanding, all dividends rights relating thereto shall cease and all
         rights of the holders thereof as stockholders of the Corporation
         (except the right to receive payment of the redemption price) shall
         cease.

              5.  Voting. So long as any of the Series A Preferred Stock is
                  ------
         outstanding:

<PAGE>
 
                  (a) the Corporation will not, without the affirmative vote or
         consent of the holders of at least 66 2/3% of the Series A Preferred
         Stock and any other series of Preferred Stock on a parity with the
         Series A Preferred Stock as to dividends and upon liquidation (voting
         and/or consenting as one series) at the time outstanding, given in
         person or by proxy, either in writing or by resolution adopted at an
         annual meeting or a special meeting called for the purpose, (i) create
         any other series of Preferred Stock ranking prior to, or on a parity
         with, the Series A Preferred Stock, either as to dividends or upon
         liquidation, or (ii) amend, alter or repeal any of the provisions
         hereof so as adversely to affect the preferences, rights or powers of
         the Series A Preferred Stock; provided that, nothing in this paragraph
         5 shall give the holders of Series A Preferred Stock the right to vote
         or to be consulted in respect of an increase or decrease of the number
         of shares of stock constituting the Series A Preferred Stock.

                  (b) the holders of Series A Preferred Stock shall have the
         right to vote on all matters voted upon at any meeting of shareholders
         as follows: the holders of the Series A Preferred Stock shall be
         entitled as a class to cast 66-2/3 percent of the total votes of all
         of the voting stock of the Corporation. Each share of Series A
         Preferred Stock shall be entitled to cast that proportion of the 66-2/3
         percent of the total votes of the voting stock of the Corporation which
         said one share bears to the total number of shares of Preferred Stock
         then outstanding.

                  (c) the holders of Voting Common Stock shall be entitled as a
         class to cast 33-1/3 percent of the total votes of all of the voting
         stock of the Corporation. Each share of Voting Common Stock shall be
         entitled to cast that proportion of the said 33-1/3 percent of the
         total votes of the voting stock of the Corporation which said one share
         bears to the total number of shares of Voting Common Stock then
         outstanding.

        (d)  Whether or not Preferred Stock of such series shall be subject to

to the setting aside of sums as sinking funds or redemption or purchase accounts

with the provisions of Paragraph A of this Article Fourth, then and not 
otherwise the holders of Common Stock shall be entitled to receive such 
dividends as may be declared from time to time by the Board of Directors.

involuntary liquidation, distribution or sale of assets, dissolution or 
winding-up, of the corporation, the holders of the Common Stock shall be

intangible, of whatever kind available for distribution to stockholders ratably 
in proportion to the number of shares of Common Stock held by them respectively.
<PAGE>
 
        3.  Except as may otherwise be required by law or by the provisions of

bonds, certificates of indebtedness, debentures or other securities convertible 
into or exchangeable for stock of the corporation of any class or series, or 
carrying any right to purchase stock of any class or series, but any such 
unissued stock, additional authorized issue of shares of any class or series of 
stock or securities convertible into or exchangeable for stock, or carrying any 
right to
<PAGE>
 
purchase stock, may be issued and disposed of pursuant to resolution of the 
Board of Directors to such persons, firms, corporations or associations, whether
such holders or others, and upon such terms as may be deemed advisable by the 
Board of Directors in the exercise of its sole discretion.

        2.  The relative powers, preferences and rights of each series of 
Preferred Stock in relation to the powers, preferences and rights of each other 
series of Preferred Stock shall, in each case, be as fixed from time to time by 
the Board of Directors in the resolution or resolutions adopted pursuant to 
authority granted in Paragraph A of this Article Fourth and the consent, by 
class or series vote or otherwise, of the holders of such of the series of 
Preferred Stock as are from time to time outstanding shall not be required for 
the issuance by the Board of Directors of any other series of Preferred Stock 
whether or not the powers, preferences and rights of such other series shall be 
fixed by the Board of Directors as senior to, or on a parity with, the powers, 
preferences and rights of such outstanding series, or any of them; provided, 
however, that the Board of Directors may provide in the resolution or 
resolutions as to
<PAGE>
 
any series of Preferred Stock adopted pursuant to Paragraph A of this Article 
Fourth that the consent of the holders of a majority (or such greater proportion
as shall be therein fixed) of the outstanding shares of such series voting 
thereon shall be required for the issuance of any or all other series of 
Preferred Stock.

        3.  Subject to the provisions of subparagraph 2 of this Paragraph C, 
shares of any series of Preferred Stock may be issued from time to time as the 
Board of Directors of the corporation shall determine and on such terms and for 
such consideration as shall be fixed by the Board of Directors.

of Directors of the corporation shall determine and on such terms and for such 
consideration as shall be fixed by the Board of Directors".

            (a)  Upon the terms of the Merger Agreement and subject to the

        Agreement.

            (d)  The persons listed on schedule 2.5 to the Merger Agreement and
        the officers of Marsam immediately prior to the Effective Time shall be
        the directors and officers, respectively, of the Surviving Corporation,
        until their respective successors are duly elected and qualified.

consideration being offered in relation to the current market price, also in
relation to the current value of the Corporation in a freely negotiated

customers, suppliers and other constituents of the Corporation and its
subsidiaries and on the communities in which the Corporation and its

        ELEVENTH: A.  Each person who was or is made a party or is threatened to
be made a party to or is involved in any action, suit or proceeding, whether
civil, criminal, administrative or investigative (hereinafter a "proceeding"),
by reason of the fact that he or she, or a person of whom he or she is the legal
representative, is or was a director, officer or employee of the Corporation or
is or was serving at the request of the Corporation as a director, officer,
employee or agent of another corporation or of a partnership, joint venture,
trust or other enterprise, including service with respect to employee benefit
plans, whether the basis of such proceeding is alleged action in an official
capacity while serving as a director, officer, employee or (if serving for
another corporation at the request of the Corporation) agent or in any other
capacity while serving as a director, officer, employee or (if serving for
another corporation at the request of the Corporation) agent, shall be
indemnified and held harmless by the Corporation to the fullest extent
authorized by the Delaware General Corporation Law, as the same exists or may
hereafter be amended, (but, in the case of any such amendment, only to the
extent that such amendment permits the Corporation to provide broader
indemnification rights than said law permitted the Corporation to provide prior
to such amendment) against all expense, liability and loss (including attorneys'
fees, judgment, fines, ERISA excise taxes or penalties and amounts to be paid in
settlement) reasonably incurred or suffered by such person in connection
therewith and such indemnification shall continue as to a person who has ceased
to be a director, officer, employee or (if serving for another corporation at
the request of the Corporation) agent and shall inure to the benefit of his or
her heirs, executors and administrators; provided, however, that except as
                                         --------  -------
provided in Paragraph B hereof with respect to proceedings seeking to enforce
rights to indemnification, the Corporation shall indemnify any such person
seeking indemnification in connection with a proceeding (or part thereof)
initiated by such person only if such proceeding (or part thereof) was
authorized by the Board of Directors of the Corporation. The right to
indemnification conferred in this Article ELEVENTH shall be a contract right and
shall include the right to be paid by the Corporation the expenses incurred in
defending any such proceeding in advance of its final disposition; provided,
                                                                   -------- 
however, that, if the Delaware General Corporation Law requires, the payment of
- -------                                                                        
such expenses incurred by a director or officer in his or her capacity as a
director or officer (and not in any other capacity in which service was or is
rendered by such person while a direc-

                                      -9-
<PAGE>
 
tor or officer, including, without limitation, service to an employee benefit
plan) in advance of the final disposition of a proceeding shall be made only
upon delivery to the Corporation of an undertaking, by or on behalf of such
director or officer, to repay all amounts so advanced if it shall ultimately be
determined that such director or officer is not entitled to be indemnified under
this Article ELEVENTH or otherwise.

                B.  If a claim under Paragraph A of this Article ELEVENTH is
not paid in full by the Corporation within ninety days after a written claim has
been received by the Corporation, the claimant may at any time thereafter bring
suit against the Corporation to recover the unpaid amount of the claim and, if
successful in whole or in part, the claimant shall be entitled to be paid also
the expense of prosecuting such claim. It shall be a defense to any such action
(other than an action brought to enforce a claim for expenses incurred in
defending any proceeding in advance of its final disposition where the required
undertaking, if any is required, has been tendered to the Corporation) that the
claimant has not met the standards of conduct which make it permissible under
the Delaware General Corporation Law for the Corporation to indemnify the
claimant for the amount claimed, but the burden of proving such defense shall be
on the Corporation. Neither the failure of the Corporation (including its Board
of Directors, independent legal counsel, or stockholders) to have made a
determination prior to the commencement of such action that indemnification of
the claimant is proper in the circumstances because he or she has met the
applicable standard of conduct set forth in the Delaware General Corporation
Law, nor an actual determination by the Corporation (including its Board of
Directors, independent legal counsel, or stockholders) that the claimant has not
met such applicable standard of conduct, shall be a defense to the action or
create a presumption that the claimant has not met the applicable standard of
conduct.

                C.  The right to indemnification and the payment of expenses
incurred in defending a proceeding in advance of its final disposition conferred
in this Article ELEVENTH shall not be exclusive of any other right which any
person may have or hereafter acquire under any statute, provision of the
Certificate of Incorporation, by-law, agreement, vote of stockholders or
disinterested directors or otherwise.

                D.  The Corporation may maintain insurance, at its expense, to
protect itself and any director, officer, employee or agent of the Corporation
or another corporation, partnership, joint venture, trust or other enterprise
against any expense, liability or loss, whether or not the Corporation would
have the power to indemnify such person against such expense, liability or loss
under the Delaware General Corporation Law.

<PAGE>
 
one or more of its directors or officers are directors or officers, or have a
financial interest, shall be void or voidable solely for this reason, or
solely because the director or officer is present at or participated in the
meeting of the Board of Directors or a committee thereof which authorizes the
contract or transaction, or solely because his or their votes are counted for
such purpose, if:
 
    (1) The material facts as to his interest and as to the contract or
  transaction are disclosed or are known to the Board of Directors or the
  committee, and the Board or Committee in good faith authorizes the contract
  or transaction by a vote sufficient for such purpose without counting the
  vote of the interested director or directors; or
 
    (2) The material facts as to his interest and as to the contract or
  transaction are disclosed or are known to the stockholders entitled to vote
  thereon, and the contract or transaction is specifically approved in good
  faith by the vote of the stockholders; or
 
    (3) The contract or transaction is fair as to the corporation as of the
  time it is authorized, approved or ratified, by the Board of Directors, a
  committee thereof, or the stockholders.
 
  Interested directors may be counted in determining the presence of a quorum
at a meeting of the Board of Directors or of a committee which authorizes the
contract or transaction.
 
  NINTH: (a) The corporation shall have power to indemnify any person who was
or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of
the corporation) by reason of the fact that he is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of
the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys'
 
                                       4
<PAGE>
 
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed
to the best interests of the corporation, and, with respect to any criminal
action or proceeding, had no reasonable cause to believe his conduct was
unlawful. The termination of any action, suit or proceeding by judgment,
order, settlement, conviction, or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he reasonably believed to be in or not
opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his
conduct was unlawful.
 
  (b) The corporation shall have power to indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the corporation to procure a
judgment in its favor by reason of the fact that he is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against expenses (including attorneys' fees) actually and reasonably incurred
by him in connection with the defense or settlement of such action or suit if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjusted to be liable for negligence or
misconduct in the performance of his duty to the corporation unless and only
to the extent that the Court of Chancery or the court in which such action or
suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which the Court of Chancery or such other court shall deem proper.
 
  (c) To the extent that a director, officer, employee or agent of the
corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in subsections (a) and (b), or in
defense of any claim, issue or matter therein, he shall be
 
                                       5
<PAGE>
 
indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection therewith.
 
  (d) Any indemnification under subsections (a) and (b) (unless ordered by a
court) shall be made by the corporation only as authorized in the specific
case upon a determination that indemnification of the director, officer,
employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in subsections (a) and (b). Such
determination shall be made (1) by the Board of Directors by a majority vote
of a quorum consisting of directors who were not parties to such action, suit
or proceeding, or (2) if such a quorum is not obtainable, or, even if
obtainable a quorum is disinterested directors so directs, by independent
legal counsel in a written opinion, or (3) by the stockholders.
 
  (e) Expenses incurred in defending a civil or criminal action, suit or
proceeding may be paid by the corporation in advance of the final disposition
of such action, suit or proceeding as authorized by the Board of Directors in
the manner provided in subsection (d) upon receipt of an undertaking by or on
behalf of the director, officer, employee or agent to repay such amount unless
it shall ultimately be determined that he is entitled to be indemnified by the
corporation as authorized in this section.
 
  (f) The indemnification provided by this section shall not be deemed
exclusive of any other rights to which those indemnified may be entitled under
any by-law, agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office, and shall continue as to a person
who has ceased to be a director, officer, employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such a person.
 
  (g) The corporation shall have power to purchase and maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted
against him and incurred by him in any such capacity, or arising out of his
status as such, whether or not the corporation should have the power to
indemnify him against such liability under the provisions of this section.

Article the following new Article FOURTH to read as follows:
 
    "FOURTH: The total number of shares of all classes of stock which the
  Corporation shall have authority to issue is 1,000,000 shares, which shall
  be divided into two classes consisting of 500,000 shares of Preferred
  Stock, par value $.10 per share (hereinafter referred to as "Preferred
  Stock") and 500,000 shares of Common Stock, par value $.10 per share
  (hereinafter referred to as "Common Stock").
 
                                       1
<PAGE>
 
A. PREFERRED STOCK.
 
  (1) 150,000 shares of Preferred Stock are hereby constituted as a series of
Preferred Stock designated as "Preferred Stock, Series A" (hereinafter
referred to as "Series A Stock") with the powers, preferences and rights
hereinafter set forth.
 
  (a) The holders of the Series A Stock shall be entitled to receive, with
respect to each fiscal year of the Corporation during which any of the Series
A Stock is outstanding, cash dividends out of the net profits realized by the
Corporation during such fiscal year, and not to exceed an annual rate of $.02
per share, payable on the first day of July in the succeeding fiscal year, if,
as and when declared by the Board of Directors, out of funds at the time
legally available for the payment of dividends. Dividends on the Series A
Stock, to the extent equal to the net profits realized by the Corporation as
aforesaid, shall be cumulative and shall accrue from and after the date of
issuance thereof. No dividends shall be declared, paid or set apart for
payment on any other series of Preferred Stock or on Common Stock unless and
until all dividends
 
                                       2
<PAGE>
 
on the Series A Stock that have accrued for all past dividend periods and the
annual dividend on the Series A Stock for the current dividend period to the
extent accrued shall have been paid or declared and a sum sufficient for the
payment thereof set apart.
 
  (b) In the event of any liquidation, dissolution or winding up of the
Corporation, before any payment or distribution of the assets of the
Corporation (whether capital or surplus) shall be made to or set apart for the
holders of any other series of Preferred Stock or of Common Stock, the holders
of Series A Stock shall be entitled to receive payment of an amount equal to
$.40 per share plus an amount equal to all unpaid cumulative dividends accrued
thereon, pursuant to subparagraph (1)(a) hereof to the date of final
distribution to such holders, and no more. If the assets of the Corporation,
or the proceeds thereof available for distribution to its shareholders shall
be insufficient to pay in full all amounts to which the holders of Series A
Stock are entitled, then such assets or the proceeds thereof shall be
distributed among such holders ratably in accordance with the respective
amounts which would be payable on such shares if all amounts payable were paid
in full. For the purposes of this sub-paragraph (1)(b), the voluntary sale,
lease, exchange or transfer of all or substantially all of the Corporation's
assets, or the consolidation or merger of the Corporation with or into any
other
 
                                       3
<PAGE>
 
corporation shall not be deemed to be a liquidation, dissolution or winding up
of the Corporation.
 
  (c) The Corporation may, at its option, at any time or from time to time,
redeem the whole or any part of the Series A Stock at a redemption price equal
to $.40 per share, plus an amount equal to all unpaid cumulative dividends
accrued thereon, pursuant to subparagraph (1)(a) hereof, to the date of
redemption. In the event the Corporation shall determine to redeem less than
all of the shares of the Series A Stock then outstanding, the Board of
Directors shall determine the shares of Series A Stock so to be redeemed by
lot or pro rata or by any other means which the Board of Directors deems
equitable. Notice of any proposed redemption of any Series A Stock shall be
given by the Corporation by mailing a copy of such notice at least thirty (30)
days prior to the date fixed for such redemption to the holders of record of
the Series A Stock to be redeemed, at their respective addresses appearing on
the books of the Corporation. If on the redemption date specified in such
notice, the funds necessary for such redemption shall have been set aside by
the Corporation, separate and apart from its other funds, in trust for the pro
rata benefit of the holders of the shares so called for redemption, then,
notwithstanding that any certificates for shares of Series A Stock so called
for redemption shall not have been surrendered for cancellation, the shares
represented there-
 
                                       4
<PAGE>
 
by shall no longer be deemed outstanding, all dividends thereon shall cease to
accrue and all rights of the holders thereof as stockholders of the Corporation
(except the right to receive payment of the redemption price and accrued and
unpaid cumulative dividends to the date of redemption) shall cease and
determine.
 
  (d) So long as any of the Series A Stock is outstanding the Corporation will
not, without the affirmative vote or consent of the holders of at least 66 2/3%
of the Series A Stock at the time outstanding, given in person or by proxy,
either in writing or by resolution adopted at an annual meeting or a special
meeting called for the purpose, (i) create any other class or series of stock
ranking prior to, or on a parity with, the Series A Stock, either as to
dividends or upon liquidation, or increase the authorized number of shares of
any such other class or series of stock or of the Series A Stock, or (ii)
amend, alter or repeal any of the provisions hereof so as adversely to affect
the preferences, rights or powers of the Series A Stock.
 
  (e) Except as specifically provided in this subparagraph (1) or as otherwise
required by law, no holder of the Series A Stock shall be entitled to any
voting rights
 
                                       5
<PAGE>
 
or to receive notice of, or participate in, any meeting of stockholders.
 
  (2) Subject to the provisions of subparagraph (1) above, the designations,
powers, preferences and rights in respect of shares of Preferred Stock other
than shares of Series A Stock shall be as follows:
 
  Shares of Preferred Stock may be issued from time to time in one or more
series, as may from time to time de determined by the Board of Directors, each
of said series to be distinctly designated. All shares of any one series of
Preferred Stock shall be alike in every particular, except that there may be
different dates from which dividends, if any, thereon shall be cumulative, if
made cumulative. The voting powers and the preferences and relative,
participating, optional and other special rights of each such series, and the
qualifications, limitations or restrictions thereof, if any, may differ from
those of any and all other series at any time outstanding; and the Board of
Directors of the Corporation is hereby expressly granted authority to fix by
resolution or resolutions adopted prior to the issuance of any shares of a
particular series of Preferred Stock, the voting powers and the designations,
preferences and relative, optional and other special rights, and the
qualifications, limitations and restrictions of such series, including, but

the generality of the foregoing, the following:
 
    (a) The distinctive designation of, and the number of shares of Preferred

  time by like action of the Board of Directors;
 
    (b) The rate and times at which, and the terms and conditions on which,
  dividends, if any, on Preferred Stock of such series shall be paid, the
  extent of the preference or relation, if any, of such dividends to the
  dividends payable on any other class or classes, or series of the same or
  other classes of stock and whether such dividends shall be cumulative or
  non-cumulative;
 
    (c) The right, if any, of the holders of Preferred Stock of such series
  to convert the same into, or exchange the same for, shares of any other
  class or classes or of any series of the same or any other class or classes
  of stock of the Corporation and the terms and conditions of such conversion
  or exchange;
 
                                       7
<PAGE>

  redemption, and the redemption price or prices and the time or times at
  which, and the terms and conditions on which, Preferred Stock of such
  series may be redeemed;
 
    (e) The rights, if any, of the holders of Preferred Stock of such series
  upon the voluntary or involuntary liquidation, merger, consolidation,
  distribution or sale of assets, dissolution or winding-up, of the
  Corporation;
 
    (f) The terms of the sinking fund or redemption or purchase account, if
  any, to be provided for the Preferred Stock of such series; and
 
    (g) The voting powers, if any, of the holders of such series of Preferred

  the right, voting as a series by itself or together with other series of
  Preferred Stock or all series of Preferred Stock as a class, to elect one
  or more directors of the Corporation if there shall have been a default in
  the payment of dividends on any one or more series of Preferred Stock or
  under such other circumstances and on such conditions as the Board of
  Directors may determine; provided,

Article Fourth, the relative powers, preferences and rights of each series of
Preferred Stock in relation to the powers, preferences and rights of each other
series of Preferred Stock shall, in each case, be as fixed from time to time by
the Board of Directors in the resolution or resolutions adopted pursuant to
authority granted in Paragraph A of this Article Fourth and the consent, by
class or series vote or otherwise, of the holders of such of the series of
Preferred Stock as are from time to time outstanding shall not be required
<PAGE>
 
for the issuance by the Board of Directors of any other series of Preferred
Stock whether or not the powers, preferences and rights of such other series
shall be fixed by the Board of Directors as senior to, or on a parity with,
the powers, preferences and rights of such outstanding series, or any of them;
provided, however, that the Board of Directors may provide in the resolution
or resolutions as to any series of Preferred Stock adopted pursuant to

majority (or such greater proportion as shall be therein fixed) of the
outstanding shares of such series voting thereon shall be required for the
issuance of any or all other series of Preferred Stock.

               GENERAL CORPORATION LAW OF THE STATE OF DELAWARE)
 
  It is hereby certified that:

    Upon the filing in the office of the Secretary of State of the State of

  value $.10 per share, shall

  $.01 per share. No scrip or fractional shares will be issued by reason of
  this Amendment.
 
  3. In lieu of a vote, written consent to the foregoing amendment has been

the Corporation shall have been eliminated.

Incorporation of the Corporation in corrected form is as follows:
 
  "Upon the filing in the office of the Secretary of State of Delaware of
  this Certificate of Amendment to the Certificate of Incorporation whereby
  this Article Fourth is amended to read as set forth herein, each 500 issued
  and outstanding shares of voting Common Stock, par value $.01 per share, of
  the Corporation shall be automatically reclassified as and changed into one
  validly issued, fully paid and nonassessable share of voting Common Stock,
  par value $.01 per share, each issued and outstanding share of non-voting
  Common Stock, par value $.10 per share, of the Corporation shall be
  canceled and all authorized shares of such non-voting Common Stock shall be
  eliminated, and each

  value $.01 per share. No scrip or fractional shares will be issued by
  reason of this Amendment."

                               ----------------
 
                                   ARTICLE I
 
                                 STOCKHOLDERS
 
  1. CERTIFICATES REPRESENTING STOCK. Every holder of stock in the corporation
shall be entitled to have a certificate signed by, or in the name of, the
corporation by the Chairman or Vice-Chairman of the Board of Directors, if
any, or by the President or a Vice-President and by the Treasurer or an
Assistant Treasurer or the Secretary or an Assistant Secretary of the
corporation certifying the number of shares owned by him in the corporation.
If such certificate is countersigned by a transfer agent other than the
corporation or its employee or by a registrar other than the corporation or
its employee, any other signature on the certificate may be a facsimile. In
case any officer, transfer agent, or registrar who has signed or whose
facsimile signature has been placed upon a certificate shall have ceased to be
such officer, transfer agent, or registrar before such certificate is issued,
it may be issued by the corporation with the same effect as if he were such
officer, transfer agent, or registrar at the date of issue.
 
  Whenever the corporation shall be authorized to issue more than one class of
stock or more than one series of any class of stock, and whenever the
corporation shall issue any shares of its stock as partly paid stock, the
certificates representing shares of any such class or series or of any such
partly paid stock shall set forth thereon the statements prescribed by the
General Corporation Law. Any restrictions on the transfer or registration of
transfer of any shares of stock of any class or series shall be noted
conspicuously on the certificate representing such shares.
 
  The corporation may issue a new certificate of stock in place of any
certificate theretofore issued by it, alleged to have been lost, stolen, or
destroyed, and the Board of Directors may require the owner of any lost,
stolen, or destroyed certificate, or his legal representative, to give the
corporation a bond sufficient to indemnify the corporation against any claim
that may be made against it on account of the alleged
<PAGE>
 
loss, theft, or destruction of any such certificate or the issuance of any
such new certificate.
 
  2. FRACTIONAL SHARE INTERESTS. The corporation may, but shall not be
required to, issue fractions of a share. In lieu thereof it shall either pay
in cash the fair value of fractions of a share, as determined by the Board of
Directors, to those entitled thereto or issue scrip or fractional warrants in
registered or bearer from over the manual or facsimile signature of an officer
of the corporation or of its agent, exchangeable as therein provided for full
shares, but such scrip or fractional warrants shall not entitle the holder to
any rights of a shareholder except as therein provided. Such scrip or
fractional warrants may be issued subject to the condition that the same shall
become void if not exchanged for certificates representing full shares of
stock before a specified date, or subject to the condition that the shares of
stock for which such scrip or fractional warrants are exchangeable may be sold
by the corporation and the proceeds thereof distributed to the holders of such
scrip or fractional warrants, or subject to any other conditions which the
Board of Directors may determine.
 
  3. STOCK TRANSFERS. Upon compliance with provisions restricting the transfer
or registration of transfer of shares of stock, if any, transfers or
registration of transfers of shares of stock of the corporation shall be made
only on the stock ledger of the corporation by the registered holder thereof,
or by his attorney thereunto authorized by power of attorney duly executed and
filed with the Secretary of the corporation or with a transfer agent or a
registrar, if any, and on surrender of the certificate or certificates for
such shares of stock properly endorsed and the payment of all taxes due
thereon.
 
  4. RECORD DATE FOR STOCKHOLDERS. For the purpose of determining the
stockholders entitled to notice of or to vote at any meeting of stockholders
or any adjournment thereof, or to express consent to or dissent from any
corporate action in writing without a meeting, or for the purpose of
determining stockholders entitled to receive payment of any dividend or other
distribution or the allotment of any rights, or entitled to exercise any
rights in respect of any change, conversion, or exchange of stock, or for the
purpose of any other lawful action, the directors may fix, in advance, a date
as the record date for any such determination of stockholders. Such date shall
not be more than sixty days not less than ten days before the date of such
meeting, nor more than sixty days prior to any other action. If no record date
is fixed, the record date for the determination of stockholders entitled to
notice of or to vote at a meeting of stockholders shall be at the close of
business on the day next preceding the day on which
 
                                       2
<PAGE>
 
notice is given, or, of notice is waived, at the close of business on the day
next preceding the day on which the meeting is held; the record date for
determining stockholders for any other purpose shall be at the close of
business on the day on which the Board of Directors adopts the resolution
relating thereto. When a determination of stockholders of record entitled to
notice of or to vote at any meeting of stockholders has been made as provided
in this paragraph, such determination shall apply to any adjournment thereof;
provided, however, that the Board of Directors may fix a new record date for
the adjourned meeting.
 
  5. MEANING OF CERTAIN TERMS. As used herein in respect of the right to notice
of a meeting of stockholders or a waiver thereof or to participate or vote
thereat or to consent or dissent in writing in lieu of a meeting, as the case
may be, the term "share" or "shares" or "share of stock" or "shares of stock"
or "stockholder" or "stockholders" refers to an outstanding share or shares of
stock and to a holder or holders of record of outstanding shares of stock when
the corporation is authorized to issue only one class of shares of stock, and
said reference is also intended to include any outstanding share or shares of
stock and any holder or holders of record of outstanding shares of stock of any
class upon which or upon whom the certificate of incorporation confers such
rights where there are two or more classes or series of shares of stock or upon
which or upon whom the General Corporation Law confers such rights
notwithstanding that the certificate of incorporation may provide for more than
one class or series of shares of stock, one or more of which are limited or
denied such rights thereunder; provided, however, that no such right shall vest
in the event of an increase or a decrease in the authorized number of shares of
stock of any class or series which is otherwise denied voting rights under the
provisions of the certificate of incorporation.
 
6. STOCKHOLDER MEETINGS.
 
  --TIME. The annual meeting shall be held on the date and at the time fixed,
from time to time, by the directors, provided, that the first annual meeting
shall be held on a date within thirteen months after the organization of the
corporation, and each successive annual meeting shall be held on a date within
thirteen months after the date of the preceding annual meeting. A special
meeting shall be held on the date and at the time fixed by the directors.
 
  --PLACE. Annual meetings and special meetings shall be held at such place,
within or without the State of Delaware, as the directors may, from time to
time, fix. Whenever the directors shall fail to fix such place, the meeting
shall be held at the registered office of the corporation in the State of
Delaware.
 
                                       3
<PAGE>
 
  --CALL. Annual meetings and special meetings may be called by the directors
or by any officer instructed by the directors to call the meeting.
 
  --NOTICE OF WAIVER OF NOTICE. Written notice of all meetings shall be given,
stating the place, date, and hour of the meeting and stating the place within
the city or other municipality or community at which the list of stockholders
of the corporation may be examined. The notice of an annual meeting shall
state that the meeting is called for the election of directors and for the
transaction of other business which may properly come before the meeting, and
shall, (if any other action which could be taken at a special meeting is to be
taken at such annual meeting) state the purpose or purposes. The notice of a
special meeting shall in all instances state the purpose or purposes for which
the meeting is called. If any action is proposed to be taken which would, if
taken, entitle stockholders to receive payment for their shares of stock, the
notice shall include a statement of that purpose and to that effect. Except as
otherwise provided by the General Corporation Law, a copy of the notice of any
meeting shall be given, personally or by mail, no less than ten days nor more
than fifty days before the date of the meeting, unless the lapse of the
prescribed period of time shall have been waived, and directed to each
stockholder at his record address or at such other address which he may have
furnished by request in writing to Secretary of the corporation. Notice by
mail shall be deemed to be given when deposited, with postage thereon prepaid,
in the United States mail. If a meeting is adjourned to another time, not more
than thirty days hence, and/or to another place, and if an announcement of the
adjourned time and/or place is made at the meeting, it shall not be necessary
to give notice of the adjourned meeting unless the directors, after
adjournment, fix a new record date for the adjourned meeting. Notice need not
be given to any stockholder who submits a written waiver of notice by him
before or after the time stated therein. Attendance of a person at a meeting
of stockholders shall constitute a waiver of notice of such meeting, except
when the stockholder attends a meeting for the express purpose of objecting,
at the beginning of the meeting, to the transaction of any business because
the meeting is not lawfully called or convened. Neither the business to be
transacted at, nor the purpose of, any regular or special meeting of the
stockholders need to be specified in any written waiver of notice.
 
  --STOCKHOLDER LIST. The officer who has charge of the stock ledger of the
corporation shall prepare and make, at least ten days before every meeting of
stockholders, a complete list
 
                                       4
<PAGE>
 
of stockholders, arranged in alphabetical order, and showing the address of
each stockholder and the number of shares registered in the name of each
stockholder. Such list shall be open to the examination of any stockholder, for
any purpose germane to the meeting, during ordinary business hours, for a
period of at least ten days prior to the meeting, either at a place within the
city or other municipality or community where the meeting is to be held, which
place shall be specified in the notice of the meeting, or if not so specified,
at the place where the meeting is to be held. The list shall also be produced
and kept at the time and place where the meeting is to be held. The list shall
also be produced and kept at the time and place of the meeting during the whole
time thereof, and may be inspected by any stockholder who is present. The stock
ledger shall be the only evidence as to who are the stockholders entitled to
examine the stock ledger, the list required by this section or the books of the
corporation, or to vote at any meeting of stockholders.
 
  --CONDUCT OF MEETING. Meetings of the stockholders shall be presided over by
one of the following officers in the order of seniority and if present and
acting--the Chairman of the Board, if any, the Vice-Chairman of the Board, if
any, the President, a Vice-President, or, if none of the foregoing is in office
and present and acting, by a chairman to be chosen by the stockholders. The
Secretary of the corporation, or in his absence, an Assistant Secretary, shall
act as secretary of every meeting, but if neither the Secretary nor an
Assistant Secretary is present the Chairman of the meeting shall appoint a
secretary of the meeting.
 
  --PROXY REPRESENTATION. Every stockholder may authorize another person or
persons to act for him by proxy in all matters in which a stockholder is
entitled to participate, whether by waiver notice of any meeting, voting or
participating at a meeting, or expressing consent or dissent without a meeting.
Every proxy must be signed by the stockholder or by his attorney-in-fact. No
proxy shall be voted or acted upon after three years from its date unless such
proxy provides for a longer period. A duly executed proxy shall be irrevocable
if it states that it is irrevocable and, if, and only as long as, it is coupled
with an interest sufficient in law to support an irrevocable power. A proxy may
be made irrevocable regardless of whether the interest with which it is coupled
is an interest in the stock itself or an interest in the corporation generally.
 
  --INSPECTORS AND JUDGES. The directors, in advance of any meeting, may, but
need not, appoint one or more inspectors of election or judges of the vote, as
the case may be,
 
                                       5
<PAGE>
 
to act at the meeting or any adjournment thereof. If an inspector or inspectors
or judge or judges are not appointed, the person presiding at the meeting may,
but need not, appoint one or more inspectors or judges. In case any person who
may be appointed as an inspector or judge fails to appear or act, the vacancy
may be filled by appointment made by the directors in advance of the meeting or
at the meeting by the person presiding thereat. Each inspector or judge, if
any, before entering upon the discharge of his duties, shall take and sign an
oath faithfully to execute the duties of inspector or judge at such meeting
with strict impartiality and according to the best of his ability. The
inspectors or judges, if any, shall determine the number of shares of stock
outstanding and the voting power of each, the shares of stock represented at
the meeting, the existence of a quorum, the validity and effect of proxies, and
shall receive votes, ballots or consents, hear and determine all challenges and
questions arising in connection with the right to vote, count and tabulate all
votes, ballots or consents, determine the result, and do such acts as are
proper to conduct the election or vote with fairness to all stockholders. On
request of the person presiding at the meeting, the inspector or inspectors or
judge or judges, if any, shall make a report in writing of any challenge,
question or matter determined by him or them and execute a certificate of any
fact found by him or them.
 
  --QUORUM. The holders of a majority of the outstanding shares of stock shall
constitute a quorum at a meeting of stockholders for the transaction of any
business. The stockholders present may adjourn the meeting despite the absence
of a quorum.
 
  --VOTING. Each share of stock shall entitle the holder thereof to one vote.
In the election of directors, a plurality of the votes cast shall elect. Any
other action shall be authorized by a majority of the votes cast except where
the General Corporation Law prescribes a different percentage of votes and/or a
different exercise of voting power. In the election of directors, voting need
not be by ballot. Voting by ballot shall not be required for any other
corporate action except as otherwise provided by the General Corporation Law.
 
  --STOCKHOLDER ACTION WITHOUT MEETINGS. Whenever the vote of stockholders at a
meeting thereof is required or permitted to be taken for or in connection with
any corporate action, the meeting and vote of stockholders may be dispensed
with if all of the stockholders who would have been entitled to vote upon the
action if such meeting were held shall consent in writing to such corporate
action being taken; or if less than all of said stockholders, but not less than
those having at least the minimum voting power required to take corporate
action under the provisions of the General Corporation Law, shall consent in
writing
 
                                       6
<PAGE>
 
to such corporate action; provided that prompt notice be given to all
stockholders of the taking of such action without a meeting and by less than
unanimous written consent.
 
                                  ARTICLE II
 
                                   DIRECTORS
 
  1. FUNCTIONS AND DEFINITIONS. The business of the corporation shall be
managed by the Board of Directors of the corporation. The use of the phrase
"whole board" herein refers to the total number of directors which the
corporation would have if there were no vacancies.
 
  2. QUALIFICATIONS AND NUMBER. A director need not be a stockholder, a
citizen of the United States, or a resident or the State of Delaware. The
initial Board of Directors shall consist of two persons. Thereafter the number
of directors constituting the whole board shall be at least three, except
that, where all the shares of stock of the corporation are owned beneficially
and of record by less than three stockholders, the number of directors may be
less than three but not less than the number of such stockholders. Subject to
the foregoing limitation and except for the first Board of Directors, such
number may be fixed from time to time by action of the stockholders or of the
directors, or, if the number is not fixed, the number shall be two. The number
of directors may be increased or decreased by action of the stockholders or of
the directors.
 
  3. ELECTION AND TERM. The first Board of Directors, unless the members
thereof shall have been named in the certificate of incorporation, shall be
elected by the incorporator or incorporators and shall hold office until the
first annual meeting of stockholders and until their successors have been
elected and qualified or until their earlier resignation or removal. Any
director may resign at any time upon written notice to the corporation.
Thereafter, directors who are elected at an annual meeting of stockholders,
and directors who are elected in the interim to fill vacancies and newly
created directorships, shall hold office until the next annual meeting of
stockholders and until their successors have been elected and qualified or
until their earlier resignation or removal. In the interim between annual
meetings of stockholders or of special meetings of stockholders called for the
election of directors and/or for the removal of one or more directors and for
the filling of any vacancy in that connection, newly created directorships and
any vacancies in the Board of Directors, including vacancies resulting from
the removal of directors for cause or without cause, may be filled by the vote
of a majority of the remaining directors then in office, although less than a
quorum, or by the sole remaining director.
 
                                       7

  4. MEETINGS.
 
  --TIME. Meetings shall be held at such time as the Board shall fix, except
that the first meeting of a newly elected Board shall be held as soon after
its election as the directors may conveniently assemble.
 
  --PLACE. Meetings shall be held at such place within or without the State of
Delaware as shall be fixed by the Board.
 
  --CALL. No call shall be required for regular meetings for which the time
and place have been fixed. Special meetings may be called by or at the
direction of the Chairman of the Board, if any, the Vice-Chairman of the
Board, if any, of the President, or of a majority of the directors in office.
 
  --NOTICE OR ACTUAL OR CONSTRUCTIVE WAIVER. No notice shall be required for
regular meetings for which the time and place have been fixed. Written, oral,
or any other mode of notice of the time and place shall be given for special
meetings in sufficient time for the convenient assembly of the directors
thereat. The notice of any meeting need not specify the purpose of the
meeting. Any requirement of furnishing a notice shall be waived by any
director who signs a written waiver of such notice before or after the time
stated therein.
 
  --QUORUM AND ACTION. A majority of the whole Board shall constitute a quorum
except when a vacancy or vacancies prevents such majority, whereupon a
majority of the directors in office shall constitute a quorum, provided, that
such majority shall constitute at least one-third of the whole Board. A
majority of the directors present, whether or not a quorum is present, may
adjourn a meeting to another time and place. Except as herein otherwise
provided, and except as otherwise provided by the General Corporation Law, the
act of the Board shall be the act by vote of a majority of the directors
present at a meeting, a quorum being present. The quorum and voting provisions
herein stated shall not be construed as conflicting with any provisions of the
General Corporation Law and these By-Laws which govern a meeting of directors
held to fill vacancies and newly created directorships in the Board.
 
  --CHAIRMAN OF THE MEETING. The Chairman of the Board if any and if present
and acting, shall preside at all meetings. Otherwise, the Vice-Chairman of the
Board, if any and if present and acting, or the President, if present and
acting, or any other director chosen by the Board, shall preside.
 
  5. REMOVAL OF DIRECTORS. Any or all of the directors may be removed for
cause or without cause by the stockholders. One or more of the directors may
be removed for cause by the Board of Directors.

<PAGE>
 
  6. COMMITTEES. The Board of Directors may, by resolution passed by a
majority of the whole Board, designate one or more committees, each committee
to consist of two or more of the directors of the corporation. The Board may
designate one or more directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee. Any
such committee, to the extent provided in the resolution of the Board, shall
have and may exercise the powers of the Board of Directors in the management
of the business and affairs of the corporation, and may authorize the seal of
the corporation to be affixed to all papers which may require it. In the
absence or disqualification of any member of any such committee or committees,
the member or members thereof present at any meeting and not disqualified from
voting, whether or not he or they constitute a quorum, may unanimously appoint
another member of the Board of Directors to act at the meeting in the place of
any such absent or disqualified member.
 
  7. ACTION IN WRITING. Any action required or permitted to be taken at any
meeting of the Board of Directors or any committee thereof may be taken
without a meeting if all members of the Board or committee, as the case may
be, consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the Board or committee.
 
                                  ARTICLE III
 
                                   OFFICERS
 
  The directors shall elect a President, a Secretary, and a Treasurer, and may
elect a Chairman of the Board of Directors, a Vice-Chairman thereof, and one
or more Vice-Presidents, Assistant Secretaries, and Assistant Treasurers, and
may elect or appoint such other officers and agents as are desired. The
President may but need not be a director. Any number of offices may be held by
the same person.
 
  Unless otherwise provided in the resolution of election or appointment, each
officer shall hold office until the meeting of the Board of Directors
following the next annual meeting of stockholders and until his successor has
been elected and qualified. Any officer may resign at any time upon written
notice.
 
  Officers shall have the powers and duties defined in the resolutions
appointing them; provided, that the Secretary shall record all proceedings of
the meetings or of the written actions of the stockholders and of the
directors, and any committee thereof, in a book to be kept for that purpose.

  The corporate seal shall be in such form as the Board of Directors shall
prescribe.
 
                                   ARTICLE V

change, by the Board of Directors.
 
                                  ARTICLE VI
 
                                  AMENDMENTS
 
  The by-laws of the corporation may be made, and shall be subject to
alteration and repeal, by the stockholders of the corporation, at any annual
or special meeting, and by the board of directors at any regular or special
meeting, provided, however, that by-laws made or altered by the Board of
Directors may be altered or repealed by the stockholders at any annual or
special meeting.

application of trustees in dissolution or of any receiver or receivers
appointed for the Corporation under the provisions of section 279 of Title 8
of the Delaware Code order a meeting of the creditors or class of creditors,
and/or of the stockholders or class of stockholders of the Corporation, as the

reorganization of the Corporation as a consequence of such compromise or

          SECTION 2. OTHER OFFICES.----The corporation may have other offices,
either within or without the State of Delaware, at such place or places as the
Board of Directors may from time to time appoint or the business of the

                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

          SECTION 1. ANNUAL MEETINGS. --Annual meetings of stockholders for the
election of directors and for such other business as may be stated in the notice
of the meeting, shall be held at such place, either within or without the State
of Delaware, and at such time and date as the Board of Directors, by resolution,
shall determine and as set forth in the notice of the meeting.

          If the date of the annual meeting shall fall upon a legal holiday, the
meeting shall be held on the next succeeding business day. At each annual
meeting, the stockholders entitled to vote shall elect a Board of Directors and
they may transact such other corporate business as shall be stated in the notice
of the meeting.

          SECTION 2. OTHER MEETINGS.--Meetings of stockholders for any purpose
other than the election of directors may be held at such time and place, within

meeting.

          SECTION 3. VOTING.--Each stockholder entitled to vote in accordance
with the terms of the Certificate of Incorporation and these By-Laws shall be
entitled to one vote, in person or by proxy, for each share of stock entitled to
vote held by such stockholder, but no proxy shall be voted after three years
from its date unless such proxy provides for a longer period. Upon the demand of
any stockholder, the vote for directors and the
<PAGE>
 
vote upon any question before the meeting, shall be by ballot. All elections for
directors shall be decided by plurality vote; all other questions shall be
decided by majority vote except as otherwise provided by the Certificate of
Incorporation or the laws of the State of Delaware.

          A complete list of the stockholders entitled to vote at the ensuing
election, arranged in alphabetical order, with the address of each, and the
number of shares held by each, shall be open to the examination of any
stockholder, for any purpose germane to the meeting, during ordinary business
hours for a period of at least ten days prior to the meeting, either at a place
within the city where the meeting is to be held, which place shall be specified
in the notice of the meeting, or, if not so specified, at the place where the
meeting is to be held. The list shall also be produced and kept at the time and
place of the meeting during the whole time thereof, and may be inspected by any
stockholder who is present.

          SECTION 4. QUORUM.--Except as otherwise required by law, by the
Certificate of Incorporation or by these By-Laws, the presence, in person or by
proxy, of stockholders holding a majority of the stock of the corporation
entitled to vote shall constitute a quorum at all meetings of the stockholders.
In case a quorum shall not be present at any meeting, a majority in interest of
the stockholders entitled to vote thereat, present in person or by proxy, shall
have power to adjourn the meeting from time to time, without notice other than
announcement at the meeting, until the requisite amount of stock entitled to
vote shall be present. At any such adjourned meeting at which the requisite
amount of stock entitled to vote shall be represented, any business may be
transacted which might have been transacted at the meeting as originally
noticed; but only those stockholders entitled to vote at the meeting as
originally noticed shall be entitled to vote at any adjournment or adjournments
thereof.

          SECTION 5. SPECIAL MEETINGS. --Special meetings of the stockholders
for any purpose or purposes may be called by the President or Secretary, or by

date and time of the meeting, and the general nature of the business to be
considered, shall be given to each stockholder entitled to vote thereat at his

more than sixty days before the date of the meeting. No business other than that
stated in the notice shall be transacted at any meeting without the unanimous
consent of all the stockholders entitled to vote thereat.

          SECTION 7. ACTION WITHOUT MEETING.--Unless otherwise provided by the
Certificate of Incorporation, any action required to be taken at any annual or
special meeting of stockholders, or any action which may be taken at any annual
or special meeting, may be taken without a meeting, without prior notice and
without a vote, if a consent in writing, setting forth the action so taken,
shall be signed by the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and
voted. Prompt notice of the taking of the corporate action without a meeting by
less than unanimous written consent shall be given to those stockholders who
have not consented in writing.

                                  ARTICLE III

                                   DIRECTORS

          SECTION 1. NUMBER AND TERM.--The number of directors constituting the
Board of Directors shall be not more than nine nor less than one, as fixed from
time to time by action of the stockholders or the Board of Directors. The
directors shall be elected at the annual meeting of the stockholders and each
director shall be elected to serve until his or her successor shall be elected
and shall qualify. Directors need not be stockholders.

          SECTION 2. RESIGNATIONS.--Any director, member of a committee or other
officer may resign at any time. Such resignation shall be made in writing, and
shall take effect at the time specified therein, and if no time be specified, at
the time of its receipt by the President or Secretary. The acceptance of a
resignation shall not be necessary to make it effective.

          SECTION 3. VACANCIES.--If the office of any director, member of a
committee or other officer becomes vacant, the remaining directors in office,
though less than a quorum by a majority vote, may appoint any qualified person
to fill such vacancy, who shall hold office for the unexpired term and until his
or her successor shall be duly chosen provided, however, that if there are no
directors then in office due to such a vacancy, the stockholders may elect a
successor who shall hold office for the unexpired term and until his or her
successor shall be elected and qualified.

          SECTION 4. REMOVAL.--Except as hereinafter provided, any director or
directors may be removed either for or without cause at any time by the
affirmative vote of the holders of a majority of all the shares of stock
outstanding and entitled to vote, at a special meeting of the stockholders
called for that purpose, and the vacancies thus created may be filled, at the

                                       3
<PAGE>
 
meeting held for the purpose of removal, by the affirmative vote of a majority
in interest of the stockholders entitled to vote.

          Unless the Certificate of Incorporation otherwise provides,
stockholders may effect removal of a director who is a member of a classified
Board of Directors only for cause. If the Certificate of Incorporation provides
for cumulative voting and if less than the entire board is to be removed, no
director may be removed without cause if the votes cast against his removal
would be sufficient to elect him or her if then cumulatively voted at an
election of the entire board of directors, or, if there be classes of directors,
at an election of the class of directors of which he or she is a part.

          If the holders of any class or series are entitled to elect one or
more directors by the provisions of the Certificate of Incorporation, these
provisions shall apply, in respect to the removal without cause of a director or
directors so elected, to the vote of the holders of the outstanding shares of
that class or series and not to the vote of the outstanding shares as a whole.

          SECTION 5. INCREASE OF NUMBER.---The number of directors may be
increased by the affirmative vote of a majority of the directors, though less
than a quorum, or, by the affirmative vote of a majority in interest of the
stockholders, at the annual meeting or at a special meeting called for that
purpose, and by like vote the additional directors may be chosen at such meeting
to hold office until the next annual election and until their successors are
elected and qualify.

          SECTION 6. POWERS.--The Board of Directors shall exercise all of the
powers of the corporation except such as are by law, or by the Certificate of
Incorporation of the corporation or by these By--Laws conferred upon or reserved
to the stockholders.

          SECTION 7. COMMITTEES.--The Board of Directors may, by resolution or
resolutions passed by a majority of the whole board, designate one or more
committees, each committee to consist of one or more of the directors of the
corporation. The board may designate one or more directors as alternate members
of any committee, who may replace any absent or disqualified member at any
meeting of the committee. In the absence or disqualification of any member of
such committee or committees, the member or members thereof present at any
meeting and not disqualified from voting, whether or not he, she or they
constitute a quorum, may unanimously appoint another member of the Board of
Directors to act at the meeting in the place of any such absent or disqualified
member.

          Any such committee, to the extent provided in the resolution of the
Board of Directors, or in these By-Laws, shall

                                       4
<PAGE>
 
have and may exercise all the powers and authority of the Board of Directors in
the management of the business and affairs of the corporation, and may authorize
the seal of the corporation to be affixed to all papers which may require it;
but no such committee shall have the power or authority in reference to amending
the Certificate of Incorporation, adopting an agreement of merger or
consolidation, recommending to the stockholders the sale, lease or exchange of
all or substantially all of the corporation's property and assets, recommending
to the stockholders a dissolution of the corporation or a revocation of a
dissolution, or amending the By-Laws of the corporation; and, unless the
resolution, these By-Laws or the Certificate of Incorporation expressly so
provide, no such committee shall have the power or authority to declare a
dividend or to authorize the issuance of stock.

          SECTION 8. MEETINGS.--The newly elected directors may hold their first
meeting for the purpose of organization and the transaction of business, if a
quorum be present, immediately after the annual meeting of the stockholders; or
the time and place of such meeting may be fixed by consent in writing of all the
directors.

          Regular meetings of the directors may be held without notice at such
places and times as shall be determined from time to time by resolution of the
directors.

          Special meetings of the board may be called by the President or by the
Secretary on the written request of any two directors on at least two days'
notice to each director and shall be held at such place or places as may be
determined by the directors, or as shall be stated in the call of the meeting.

          Unless otherwise restricted by the Certificate of Incorporation or
these By-Laws, members of the Board of Directors, or any committee designated
by the Board of Directors, may participate in a meeting of the Board of
Directors, or any committee, by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and such participation in a meeting shall
constitute presence in person at the meeting.

          SECTION 9. QUORUM.--A majority of the directors shall constitute a
quorum for the transaction of business. If at any meeting of the board there
shall be less than a quorum present, a majority of those present may adjourn the
meeting from time to time until a quorum is obtained, and no further notice
thereof need be given other than by announcement at the meeting which shall be
so adjourned.

          SECTION 10. COMPENSATION.--Directors shall not receive any stated
salary for their services as directors or as members

                                       5
<PAGE>
 
of committees, but by resolution of the board a fixed fee and expenses of
attendance may be allowed for attendance at each meeting. Nothing herein
contained shall be construed to preclude any director from serving the
corporation in any other capacity as an officer, agent or otherwise, and
receiving compensation therefor.

          SECTION 11. ACTION WITHOUT MEETING.--Any action required or permitted
to be taken at any meeting of the Board of Directors, or of any committee
thereof, may be taken without a meeting, if a written consent thereto is signed
by all members of the board, or of such committee as the case may be, and such
written consent is filed with the minutes of proceedings of the board or
committee.

                                   ARTICLE IV

          SECTION 4. PRESIDENT.--The President shall preside at all meetings of

Chairman of the Board of Directors, at all meetings of the Board of Directors,
and shall have general supervision, direction and control of the business of the
corporation subject to the authorization and control of the Board of Directors.
Except as the Board of Directors shall authorize the execution thereof in some
other manner, he shall

                                       6

                                   The Credits

     SECTION 2.01. Commitments. Subject to the terms and conditions and relying
upon the representations and warranties herein set forth, each Lender agrees,
severally and not jointly, (a) to make a term loan to the Borrower on the Tender
Offer Date in an aggregate principal amount not to exceed the Tender Facility
Commitment of such Lender, (b) to make revolving loans to the Borrower, at any
time and
<PAGE>
 
                                                                              36

from time to time on or after the Tender Offer Date and until the earlier of the
Pre-Merger Facilities Maturity Date and the termination of the Pre-Merger
Revolving Credit Commitment of such Lender in accordance with the terms hereof,
in an aggregate principal amount at any time outstanding not to exceed the
Pre-Merger Revolving Credit Commitment of such Lender, (c) to make term loans to
the Borrower, at any time and from time to time during the Term Facility
Availability Period, in an aggregate principal amount not to exceed the Term
Facility Commitment of such Lender and (d) to make revolving loans to the
Borrower, at any time and from time to time on or after the Merger Date and
until the earlier of the Post-Merger Facilities Maturity Date and the
termination of the Post-Merger Revolving Credit Commitment of such Lender in
accordance with the terms hereof, in an aggregate principal amount at any time
outstanding that will not result in (i) the Post-Merger Revolving Credit
Exposure of such Lender exceeding (ii) the Post-Merger Revolving Credit
Commitment of such Lender. Within the limits set forth in clauses (b) and (d) of
the preceding sentence, the Borrower may borrow, pay or prepay and reborrow
Pre-Merger Revolving Loans and Post-Merger Revolving Loans subject to the terms,
conditions and limitations set forth herein. Amounts paid or prepaid in respect
of Tender Facility Loans and Term Facility Loans may not be reborrowed.

     SECTION 2.02. Loans. (a) Each Loan shall be made as part of a Borrowing
consisting of Loans made by the Lenders ratably in accordance with their
applicable Tender Facility Commitments, Pre-Merger Revolving Credit Commitments,
Term Facility Commitments or Post-Merger Revolving Credit Commitments; provided,
however, that the failure of any Lender to make any Loan shall not in itself
relieve any other Lender of its obligation to lend hereunder (it being
understood, however, that no Lender shall be responsible for the failure of any
other Lender to make any Loan required to be made by such other Lender). Except
for Loans deemed made pursuant to Section 2.02(f) or 2.02(g), the Loans
comprising any Borrowing shall be in an aggregate principal amount that is (i)
an integral multiple of $1,000,000 and, in the case of a Eurodollar Borrowing,
not less than $5,000,000 or (ii) equal to the remaining available balance of the
applicable Commitments.

     (b) Subject to Sections 2.08 and 2.15, each Borrowing shall be comprised
entirely of AIR Loans or Eurodollar Loans, as the Borrower may request pursuant
to
<PAGE>
 
                                                                              37


Section 2.03. Each Lender may at its option make any Eurodollar Loan by causing
any domestic or foreign branch or Affiliate of such Lender to make such Loan;
provided, however, that (i) any exercise of such option shall not affect the
obligation of the Borrower to repay such Loan in accordance with the terms of
this Agreement and (ii) the exercise of such option shall not result in an
increase in Statutory Reserves above those applicable to members of the Federal
Reserve System. Borrowings of more than one Type may be outstanding at the same
time; Provided, however, that the Borrower shall not be entitled to request any
Borrowing that, if made, would result in more than 15 Eurodollar Borrowings
outstanding hereunder at any time. For purposes of the foregoing, Borrowings
having different Interest Periods, regardless of whether they commence on the
same date, shall be considered separate Borrowings.

     (c) Each Lender shall make each Loan to be made by it hereunder on the
proposed date thereof by wire transfer of immediately available funds to such
account in New York City as the Administrative Agent may designate not later
than 1:00 p.m., New York City time, and the Administrative Agent shall by 2:00
p.m., New York City time, credit the amounts so received to an account with the
Administrative Agent designated by the Borrower in the applicable Borrowing
Request, which account must be in the name of the Borrower, or, if a Borrowing
shall not occur on such date because any condition precedent herein specified
shall not have been met, return the amounts so received to the respective
Lenders.

     (d) Unless the Administrative Agent shall have received notice from a
Lender prior to 1:00 p.m. on the date of any Borrowing that such Lender shall
not make available to the Administrative Agent such Lender's portion of such
Borrowing, the Administrative Agent may assume that such Lender has made such
portion available to the Administrative Agent on the date of such Borrowing in
accordance with paragraph (c) above and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If the Administrative Agent shall have so made funds
available then, to the extent that such Lender shall not have made such portion
available to the Administrative Agent, the Borrower and such Lender severally
agree to repay to the Administrative Agent, in the case of the Borrower, within
one Business Day of demand, and in the case of such Lender, forthwith on demand,
such corresponding amount together with
<PAGE>
 
                                                                              38



interest thereon, for each day from and including the date such amount is made
available to the Borrower until the date such amount is repaid to the
Administrative Agent at (i) in the case of the Borrower, the interest rate
applicable at the time to the Loans comprising such Borrowing and (ii) in the
case of such Lender, a rate determined by the Administrative Agent to represent
its cost of overnight or short-term funds (which determination shall be
conclusive absent manifest error). If such Lender shall repay to the
Administrative Agent such corresponding amount, such amount shall constitute
such Lender's Loan as part of such Borrowing for purposes of this Agreement. The
Administrative Agent will promptly notify the Borrower of any Lender's failure
to make available such Lender's portion of any Borrowing if such failure
continues unremedied for one Business Day.

     (e) Notwithstanding any other provision of this Agreement, the Borrower
shall not be entitled to request any Eurodollar Borrowing if the Interest Period
requested with respect thereto would end after the Pre-Merger Facilities
Maturity Date or the Post-Merger Facilities Maturity Date, as applicable.

     (f) If the Issuing Bank shall not have received from the Borrower the
payment required to be made by Section 2.22(e) within the time specified in such
Section, the Issuing Bank shall promptly notify the Administrative Agent of the
L/C Disbursement and the Administrative Agent shall promptly notify each
Revolving Credit Lender of such L/C Disbursement and its Pro Rata Percentage
thereof. Each Revolving Credit Lender shall pay by wire transfer of immediately
available funds to the Administrative Agent not later than 2:00 p.m., New York
City time, on such date (or, if such Revolving Credit Lender shall have received
such notice later than 12:00 noon, New York City time, on any day, not later
than 10:00 a.m., New York City time, on the immediately following Business Day),
an amount equal to such Lender's Pro Rata Percentage of such L/C Disbursement
(it being understood that such amount shall be deemed to constitute an ABR
Revolving Loan of such Lender and such payment shall be deemed to have reduced
the L/C Exposure), and the Administrative Agent shall promptly pay to the
Issuing Bank amounts so received by it from the Revolving Credit Lenders. The
Administrative Agent shall promptly pay to the Issuing Bank any amounts received
by it from the Borrower pursuant to Section 2.22(e) prior to the time that any
Revolving Credit Lender makes any payment pursuant to
<PAGE>
 
                                                                              39


this paragraph (f); any such amounts received by the Administrative Agent
thereafter shall be promptly remitted by the Administrative Agent to the
Revolving Credit Lenders that shall have made such payments and to the Issuing
Bank, as their interests may appear. If any Revolving Credit Lenders shall not
have made its Pro Rata Percentage of such L/C Disbursement available to the
Administrative Agent as provided above, the Borrower and such Lender severally
to pay interest on such amount, for each day from and including the date such
amount is required to be paid in accordance with this paragraph (f) to but
excluding the date such amount is paid, to the Administrative Agent at (i) in
the case of the Borrower, a rate per annum equal to the interest rate applicable
to ABR Revolving Loans and (ii) in the case of such Lender, for the first such
day, the Federal Funds Effective Rate, and for each day thereafter, the
Alternate Base Rate. The Administrative Agent will promptly notify the Borrower
or any Lender's failure to make available such Lender's Pro Rata Percentage of
any L/C Disbursement if such failure continues unremedied for one Business Day.

     (g) If the Borrower shall exercise its right of set-off pursuant to Section
9.06(b), the amount so set off shall be deemed to be a Eurodollar Revolving Loan
with an Interest Period of one month made by the applicable Defaulting Lender on
the date, and to the extent, of such set-off.

     SECTION 2.03. Borrowing Procedure. In order to request a Borrowing (other
than a deemed Borrowing pursuant to Section 2.02(f) or 2.02(g), as to which this
Section 2.03 shall not apply), the Borrower shall telecopy (with receipt
confirmed telephonically) to the Administrative Agent a duly completed Borrowing
Request (a) in the case of a Eurodollar Borrowing, not later than 12:00 noon,
New York City time, three Business Days before a proposed Borrowing, and (b) in
the case of an ABR Borrowing, not later than 11:00 a.m., New York City time, on
the same Business Day as the proposed Borrowing is to be made. Each Borrowing
Request shall be irrevocable, shall be signed by or on behalf of the Borrower
and shall specify the following information: (i) whether being requested is to
be a Tender Facility Borrowing, a Term Facility Borrowing, a Pre-Merger
Revolving Facility Borrowing or a Post-Merger Revolving Facility Borrowing, and
whether such Borrowing is to be a Eurodollar Borrowing or an ABR Borrowing; (ii)
the date of such Borrowing (which shall be a Business Day); (iii) the
<PAGE>
 
                                                                              40


number and location of the account to which funds are to be disbursed (which
shall be an account that complies with the requirements of Section 2.02(c));
(iv) the amount of such Borrowing; and (v) if such Borrowing is to be a
Eurodollar Borrowing, the Interest Period with respect thereto; provided,
however, that, notwithstanding any contrary specification in any Borrowing
Request, each requested Borrowing shall comply with the requirements set forth
in Section 2.02. If no election as to the Type of Borrowing is specified in any
such notice, then the requested Borrowing shall be an ABR Borrowing. If no
Interest Period with respect to any Eurodollar Borrowing is specified in any
such notice, then the Borrower shall be deemed to have selected an Interest
Period of one month's duration. The Administrative Agent shall promptly (and in
any event on the same day that the Administrative Agent receives such notice, if
received by 1:00 p.m., New York City time, on such day) advise the applicable
Lenders of any notice given pursuant to this Section 2.03 (and the contents
thereof), and of each Lender's portion of the requested Borrowing.

     SECTION 2.04. Evidence of Debt; Repayment of Loans. (a) Subject to Section
9.06(b), the Borrower hereby unconditionally promises to pay to the
Administrative Agent for the account of each Lender (i) the principal amount of
each Tender Facility Loan of such Lender on the Pre-Merger Facilities Maturity
Date, (ii) the principal amount of each Term Facility Loan of such Lender as
provided in Section 2.11 and (iii) the then unpaid principal amount of each
Revolving Loin of such Lender on the applicable Maturity Date.

     (b) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness of the Borrower to such Lender
resulting from each Loan made by such Lender from time to time, including the
amounts of principal and interest payable and paid such Lender from time to time
under this Agreement.

     (c) The Administrative Agent shall maintain accounts in which it shall
record (i) the amount of each Loan made hereunder, the Type thereof and the
Interest Period applicable thereto, (ii) the amount of any principal or interest
due and payable from the Borrower to each Lender hereunder and (iii) the amount
of any sum received by the Administrative Agent hereunder from the Borrower and
each Lender's share thereof.

                                                                              41


     (d) The entries made in the accounts maintained pursuant to paragraphs (b)
and (c) above shall be prima facie evidence of the existence and amounts of the
obligations therein recorded; provided, however, that the failure of any Lender
or the Administrative Agent to maintain such accounts or any error therein shall
not in any manner affect the obligations of the Borrower to repay the Loans in
accordance with their terms, except to the extent that the correction of such
error results in a reduction of the Borrower's obligations hereunder.

     (e) Notwithstanding any other provision of this Agreement, in the event any
Lender shall request and receive a promissory note payable to such Lender and
its registered assigns to evidence the Loans made by it hereunder, the interests
represented by such note shall at all times (including after any assignment of
all or part of such interests pursuant to Section 9.04) be represented by one or
more promissory notes payable to the payee named therein or its registered
assigns.

     SECTION 2.05. Fees. (a) The Borrower shall pay to each Lender, through the
Administrative Agent, on the date of this Agreement and on the last day of
March, June, September and December in each year and on each date on which the
Tender Facility Commitment or the Pre-Merger Revolving Credit Commitment of such
Lender shall expire or be terminated as provided herein, a commitment fee (a
"Commitment Fee") equal to 0.375% per annum on the average daily unused amount
of the Tender Facility Commitment and Pre-Merger Revolving Loan Commitment of
such Lender during the preceding quarter (or other period commencing with the
date, on or prior to the date of this Agreement, on which the Borrower shall
accept the Commitments of such Lender or ending with the Pre-Merger Facilities
Maturity Date or the date on which the Commitments of such Lender shall expire
or be terminated). In addition, the Borrower shall, after the Merger Date, pay
to each Lender, through the Administrative Agent, on the last day of March,
June, September and December in each year and on the date on which the Term
Facility Commitment and the Post-Merger Revolving Credit Commitment of such
Lender shall expire or be terminated as provided herein, a Commitment Fee equal
to the Applicable Percentage per annum in effect from time to time on the
average daily unused amount of the Term Facility Commitment and the Post-Merger
Revolving Credit Commitment (taking into account such Lender's L/C Exposure as a
used amount thereof) of such Lender during the preceding quarter (or other
period

                                                                              42


commencing with the Merger Date or ending with the Post-Merger Facilities
Maturity Date or the date on which the Term Facility Commitment and the
Post-Merger Revolving Credit Commitment of such Lender shall expire or be
terminated). All Commitment Fees shall be computed on the basis of the actual
number of days elapsed in a year of 360 days. The Commitment Fee due to each
Lender shall commence to accrue on the date of acceptance by the Borrower of the
Commitment of such Lender and shall cease to accrue on the date on which the
Commitment of such Lender shall be terminated as provided herein.
Notwithstanding this paragraph (a), no Commitment Fee shall be due or payable to
any Lender that is a Defaulting Lender on the due date for payment of such
Commitment Fee.

     (b) The Borrower shall pay to the Administrative Agent, for its own
account, the administrative fees set forth in the Fee Letter at the times and in
the amounts specified therein (the "Administrative Agent Fees").

     (c) The Borrower shall pay (i) to each Revolving Credit Lender with a
Post-Merger Revolving Credit Commitment, through the Administrative Agent, on
the last day of March, June, September and December of each year (commencing
with the first such day following the Merger Date) and on the date on which the
Post-Merger Revolving Credit Commitment of such Lender shall be terminated
pursuant to Section 2.09 and no Letter of Credit shall remain outstanding, a fee
(an "L/C Participation Fee") calculated on such Lender's Pro Rata Percentage of
the average daily aggregate L/C Exposure during the preceding quarter (or other
period commencing with the Merger Date or ending with the Post-Merger Revolving
Facilities Maturity Date or the date on which all Letters of Credit have been
canceled or have expired and the Post-Merger Revolving Credit Commitments of all
Lenders shall expire or be terminated pursuant to Section 2.09) at a rate equal
to the Applicable Percentage from time to time used pursuant to Section 2.06 to
determine the interest rate on Revolving Credit Borrowings comprised of
Eurodollar Loans, and (ii) to the Issuing Bank on the last day of March, June,
September and December of each year (commencing with the first such day
following the Merger Date), a fronting fee of 0.125% per annum on the average
daily aggregate L/C Exposure during the preceding quarter (or other period
commencing with the Merger Date or ending with the Post-Merger Facilities
Maturity Date or the date on which all Letters of Credit have been canceled or
have expired and the Post-Merger

                                                                              43


Revolving Credit Commitments of all Lenders shall expire or be terminated) and,
with respect to each Letter of Credit, any other fees agreed upon by the
Borrower and the Issuing Bank plus, in connection with the issuance, amendment
or transfer of any Letter of Credit or any L/C Disbursement, the Issuing Bank's
customary documentary and processing charges, as disclosed to the Borrower prior
to the issuance of such Letter of Credit (the "Issuing Bank Fees"). All L/C
Participation Fees and Issuing Bank Fees shall be computed on the basis of the
actual number of days elapsed in a year of 360 days. Notwithstanding this
paragraph (c), no L/C Participation Fee shall be due or payable to any Lender
that is a Defaulting Lender on the due date for payment of such L/C
Participation Fee.

     (d) The payment of Fees shall be subject to Section 9.06(b). All Fees shall
be paid on the dates due, in immediately available funds, to the Administrative
Agent for distribution, if and as appropriate, among the Lenders, except that
the Issuing Bank Fees shall be paid directly to the Issuing Bank. Once paid,
none of the Fees shall be refundable under any circumstances, except to the
extent such payment shall have been made as a consequence of manifest error.

     SECTION 2.06. Interest on Loans. (a) Subject to the provisions of Section
2.07, the Loans comprising each ABR Borrowing shall bear interest (computed on
the basis of the actual number of days elapsed over a year of 365 or 366 days,
as the case may be, when the Alternate Base Rate is determined by reference to
the Prime Rate and over a year of 360 days at all other times) at a rate per
annum equal to the Alternate Base Rate plus the Applicable Percentage in effect
from time to time.

     (b) Subject to the provisions of Section 2.07, the Loans comprising each
Eurodollar Borrowing shall bear interest (computed on the basis of the actual
number of days elapsed over a year of 360 days) at a rate per annum equal to the
Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the
Applicable Percentage in effect from time to time.

     (c) The payment of interest shall be subject to Section 9.06(b). Interest
shall accrue from and including the first day of an Interest Period to but
excluding the last day of such Interest Period. Interest on each Loan shall
accrue daily for the account of the holder from time
<PAGE>
 
                                                                              44


to time of such Loan and shall be payable on the Interest Payment Dates
applicable to such Loan except as otherwise provided in this Agreement. The
applicable Alternate Base Rate or Adjusted LIBO Rate for each Interest Period or
day within an Interest Period, as the case may be, shall be determined by the
Administrative Agent, and such determination shall be conclusive absent manifest
error.

     SECTION 2.07. Default Interest. If the Borrower shall default in the
payment of the principal of or interest on any Loan or any other amount becoming
due hereunder, by acceleration or otherwise, or under any other Loan Document,
the Borrower shall on demand from time to time pay interest, to the extent
permitted by law, on such defaulted amount to but excluding the date of actual
payment (after as well as before judgment) (a) in the case of overdue principal,
at the rate otherwise applicable to such Loan pursuant to Section 2.06 plus
2.00% per annum and (b) in all other cases, at a rate per annum (computed on the
basis of the actual number of days elapsed over a year of 365 or 366 days, as
the case may be, when determined by reference to the Prime Rate and over a year
of 360 days at all other times) equal to the sum of the Alternate Base Rate plus
2.00%.

     SECTION 2.08. Alternate Rate of Interest. In the event, and on each
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for a Eurodollar Borrowing the Administrative Agent shall have
determined in good faith that dollar deposits in the principal amounts of the
Loans comprising such Borrowing are not generally available in the London
interbank market, or that the rates at which such dollar deposits are being
offered will not adequately and fairly reflect the cost any Lender of making or
maintaining its Eurodollar Loan during such Interest Period, or that reasonable
means do not exist for ascertaining the Adjusted LIBO Rate, the Administrative
Agent will, as soon as practicable thereafter, give written notice of such
determination to the Borrower and the Lenders. In the event of any such
determination, until the Administrative Agent shall have advised the Borrower
and the Lenders that the circumstances giving rise to such notice no longer
exist, any request by the Borrower for a Eurodollar Borrowing pursuant to
Section 2.03 or 2.10 shall be deemed to be a request for an ABR Borrowing. The
Administrative Agent will promptly advise the Borrower once the circumstances
giving rise to any such notice no longer exist. Each determination by the
<PAGE>
 
                                                                              45


Administrative Agent hereunder shall be conclusive absent manifest error.

     SECTION 2.09. Termination and Reduction of Commitments. (a) The Tender
Facility Commitments shall automatically terminate at 5:00 p.m., New York City
time, on the Tender Offer Date. The Term Facility Commitments shall
automatically terminate at 5:00 p.m., New York City time, on the last day of the
Term Facility Availability Period. The Pre-Merger Revolving Credit Commitments
shall automatically terminate at 5:00 p.m., New York City time, on the
Pre-Merger Facilities Maturity Date. The Post-Merger Revolving Credit
Commitments shall automatically terminate on the Post-Merger Facilities Maturity
Date. The L/C Commitment shall automatically terminate at the earlier-of (i)
5:00 p.m., New York City time, on the sixth Business Day prior to the
Post-Merger Facilities Maturity Date and (ii) the termination of the Post-Merger
Revolving Credit Commitments. Notwithstanding the foregoing, (i) all the
Commitments shall automatically terminate at 5:00 p.m., New York City time, on
December 1, 1995, if the initial Credit Event shall not have occurred by such
time and (ii) the Post-Merger Revolving Credit Commitments and the Term Facility
Commitments shall automatically terminate at 5:00, New York City time, on the
Pre-Merger Facilities Maturity Date unless the Merger shall previously have been
consummated.

     (b) Upon at least three Business nays' prior irrevocable telephonic notice
to the Administrative Agent (confirmed in writing), the Borrower may at any time
in whole permanently terminate, or from time to time in part permanently reduce,
the Tender Facility Commitments, the Term Facility Commitments, the Pre-Merger
Revolving Loan Commitments or the Post-Merger Revolving Credit Commitments;
provided, however, that (i) each partial reduction of the Commitments with
respect to any Facility shall be in an integral multiple of $1,000,000 and in a
minimum amount of $5,000,000 and (ii) the Total Revolving Credit Commitment
shall not be reduced to an amount that is less than the Aggregate Revolving
Credit Exposure at the time. Any payment of Revolving Loans pursuant to Section
2.13(a) or 2.13(c) shall automatically reduce the applicable Revolving Credit
Commitments by the amount of such payment.

     (c) Each reduction in the Tender Facility Loan Commitments, the Term
Facility Loan Commitments, the Pre-Merger Revolving Loan Commitments or the
Post-Merger
<PAGE>
 
                                                                              46


Revolving Credit Commitments hereunder shall be made ratably among the Lenders
in accordance with their respective applicable Commitments. The Borrower shall
pay to the Administrative Agent for the account of the applicable Lenders, on
the date of each termination or reduction, the Commitment Fees on the amount of
the Commitments so terminated or reduced accrued to but excluding the date of
such termination or reduction.

     SECTION 2.10. Conversion and Continuation of Borrowings. The Borrower shall
have the right at any time upon prior irrevocable telephonic notice to the
Administrative Agent (confirmed promptly in writing) (a) not later than 11:00
a.m., New York City time, on the Business Day of the proposed conversion, to
convert any Eurodollar Borrowing into an ABR Borrowing, (b) not later than 12:00
noon, New York City time, three Business Days prior to conversion or
continuation, to convert any ABR Borrowing, into a Eurodollar Borrowing or to
continue any Eurodollar Borrowing as a Eurodollar Borrowing for an additional
Interest Period, and (c) not later than 12:00 noon, New York City time, three
Business Days prior to conversion, to convert the Interest Period with respect
to any Eurodollar Borrowing to another permissible Interest Period, subject in
each case to the following:

          (i) each conversion or continuation shall be made pro rata among the
     Lenders in accordance with the respective principal amounts of the Loans
     comprising the converted or continued Borrowing;

          (ii) if less than all the outstanding principal amount of any
     Borrowing shall be converted or continued, then each resulting Borrowing
     shall satisfy the limitations specified in Sections 2.02(a) and 2.02(b)
     regarding the principal amount and maximum number of Borrowings of the
     relevant Type;

          (iii) each conversion shall be effected by each Lender and the
     Administrative Agent by recording for the account of such Lender the new
     Loan of such Lender resulting from such conversion and reducing the Loan
     (or portion thereof) of such Lender being converted by an equivalent

                                                                              47


     demand, any amounts due to the Lenders pursuant to Section 2.16;

          (v) unless each Lender otherwise agrees, any portion of a Borrowing
     maturing or required to be repaid in less than one month from the date of
     any conversion or continuation may not be converted into or continued as a
     Eurodollar Borrowing;

          (vi) any portion of a Eurodollar Borrowing that cannot be converted
     into or continued as a Eurodollar Borrowing by reason of the immediately
     preceding clause shall be automatically converted at the end of the
     Interest Period in effect for such Borrowing into an ABR Borrowing;

          (vii) no Interest Period may be selected for any Eurodollar Term
     Borrowing that would end later than a Repayment Date occurring on or after
     the first day of such Interest Period if, after giving effect to such
     selection, the aggregate outstanding amount of (A) the Eurodollar Term
     Borrowings with Interest Periods ending on or prior to such Repayment Date
     and (B) the ABR Term Borrowings would not be at least equal to the
     principal amount of Term Borrowings to be paid on such Repayment Date;

          (viii) no Borrowing may be converted into, or continued as, a
     Eurodollar Borrowing when any Default has occurred and is continuing and
     the Administrative Agent or the Required Lenders have determined that such
     conversion or continuation is not appropriate (and, instead, any such
     Borrowing will be converted into or remain as an ABR Borrowing on the last
     day of the Interest Period applicable thereto); and

          (ix) no Borrowing may be converted into, or continued as, a Eurodollar
     Borrowing when any Event of Default has occurred and is continuing, unless
     the Required Lenders have determined that such conversion or continuation
     is appropriate (and, instead, any such Borrowing will be converted into or
     remain as an ABR Borrowing on the last day of the Interest Period
     applicable thereto).

     Each notice pursuant to this Section 2.10 shall refer to this Agreement and
specify (i) the identity and amount of the Borrowing that the Borrower requests
be

                                                                              48


converted or continued, (ii) whether such Borrowing is to be converted to or
continued as a Eurodollar Borrowing or an ABR Borrowing, (iii) if such notice
requests a conversion, the date of such conversion (which shall be a Business
Day) and (iv) if such Borrowing is to be converted to or continued as a
Eurodollar Borrowing, the Interest Period with respect thereto. If no Interest
Period is specified in any such notice with respect to any conversion to or
continuation as a Eurodollar Borrowing, the Borrower shall be deemed to have
selected an Interest Period of one months duration. The Administrative Agent
shall advise the Lenders of any notice given pursuant to this Section 2.10 and
of each Lender's portion of any converted or continued Borrowing. If the
Borrower shall not have given notice in accordance with this Section 2.10 to
continue any Borrowing into a subsequent Interest Period (and shall not
otherwise have given notice in accordance with this Section 2.10 to convert such
Borrowing), such Borrowing shall, at the end of the Interest Period applicable
thereto (unless repaid pursuant to the terms hereof), automatically be continued
into a new Interest Period as an ABR Borrowing, unless such Borrowing is
comprised of Loans deemed made pursuant to Section 2.02(g), in which case such
Borrowing shall be continued as a Eurodollar Borrowing with an Interest Period
of one month.

     (b) Each prepayment of Term Loans pursuant to this Section 2.11 shall be
subject to Section 9.06(b). Each prepayment of principal of Term Facility
Borrowings pursuant to Section 2.12 or 2.13 shall be applied to reduce pro rata
the scheduled payments of principal due under this Section 2.11 after the date
of such prepayment. To the extent not previously paid, all Term Facility
Borrowings shall be due and payable on the Post-Merger Facilities Maturity Date.
Each payment of Term Facility Borrowings pursuant to this Section 2.11 shall be
accompanied by accrued interest on the principal amount paid to but excluding
the date of payment.

     SECTION 2.12. Optional Prepayment. (a) The Borrower shall have the right at
any time and from time to time to prepay any Borrowing, in whole or in part,
upon at least three Business Days' prior irrevocable telephonic notice (promptly
confirmed in writing) to the Administrative Agent before 11:00 a.m., New York
City time; provided,

                                                                              50

however, that each partial prepayment of Borrowings under any Facility shall be
in an amount that is an integral multiple of $1,000,000.

     (b) Each notice of prepayment shall specify the prepayment date and the
principal amount of each Borrowing (or portion thereof) to be prepaid and shall
commit the Borrower to prepay such Borrowing by the amount stated therein on the
date stated therein. All prepayments under this Section 2.12 shall be subject to
Section 2.16 but otherwise without premium or penalty and shall be subject to
Section 9.06(b). All prepayments under this Section 2.12 (other than prepayments
of ABR Revolving Loans) shall be accompanied by accrued interest on the
principal amount being prepaid to but excluding the date of payment.

     SECTION 2.13. Mandatory Prepayments. (a) Not later than 100 days after the
end of each fiscal year of Borrower, commencing with the fiscal year ending
December 28, 1996, the Borrower shall (i) calculate Excess Cash Flow for such
fiscal year and apply 75% of such Excess Cash Flow to prepay Borrowings in
accordance with paragraph (d) below and (ii) deliver to the Administrative Agent
a certificate signed by any Financial Officer of the Borrower setting forth the
amount, if any, of Excess Cash Flow for such period and the calculation thereof,
in reasonable detail.

     (b) In the event of any termination of all the Pre-Merger Revolving Credit
Commitments or Post-Merger Revolving Credit Commitments, the Borrower shall
repay or prepay all the outstanding Pre-Merger Revolving Facility Borrowings or
Post-Merger Revolving Facility Borrowings, respectively, on the date of such
termination. In the event of any partial reduction of the Revolving Credit
Commitments, then (i) at or prior to the effective date of such reduction, the
Administrative Agent shall notify the Borrower and the Revolving Credit Lenders
of the Aggregate Revolving Credit Exposure after giving effect thereto and (ii)
if the Aggregate Revolving Credit Exposure would exceed the Total Revolving
Credit Commitment after giving effect to such reduction or termination, then the
Borrower shall, on the date of such reduction or termination, repay or prepay
Revolving Credit Borrowings or cash-collateralize outstanding Letters of Credit
in an amount sufficient to eliminate such excess.

     (c) The Borrower shall apply 100% of Net Proceeds promptly upon its receipt
thereof (or, if applicable, promptly upon any amounts being deemed to constitute
Net Proceeds as provided in the definition of such term) to prepay Borrowings in
accordance with paragraph (d) below; provided, however, that, in the case of Net
Proceeds from an Equity Issuance, (x) the Borrower shall only be required to
apply 50% of such Net Proceeds to the prepayment of Loans if immediately prior
to receipt thereof the Leverage Ratio is greater than 3.00 to 1.00 but not
greater than 4.00 to 1.00 and 25% of such Net Proceeds to the prepayment of
Loans if at the time of receipt thereof the Leverage Ratio is greater than 2.50
to 1.00 but not greater than 3.00 to 1.00 and (y) the Borrower shall not be
required to apply any of such Net Proceeds to the prepayment of Loans if at the
time of receipt thereof the Leverage Ratio is not greater than 2.50 to 1.00. The
Borrower shall deliver to the Administrative Agent (i) at the time of each
prepayment required under this paragraph (c), a certificate signed by a
Financial Officer of the Borrower setting forth in reasonable detail the
calculation of the amount of such prepayment and (ii) not later than the later
of (A) the date on which a Responsible Officer of the Borrower becomes aware
that such prepayment will be made and (B) the date that is three Business Days
prior to the date of such prepayment, a notice of such prepayment. Such
certificate shall also describe in reasonable detail the facts and circumstances
giving rise to the applicable prepayment event and a reasonably detailed
calculation of the Net Proceeds therefrom.

     (d) Prepayments under paragraphs (a) and (c) above shall be applied first
against outstanding Term Loans and second against outstanding Revolving Loans.
Prepayments required under this Section 2.13 in respect of any Facility shall be
applied first against ABR Loans outstanding under such Facility and then against
Eurodollar Loans outstanding under such Facility.

     (e) All prepayments under this Section 2.13 shall be subject to Section
2.16 but otherwise without premium or penalty and shall be subject to Section
9.06(b). All prepayments under this Section 2.13 shall be accompanied by accrued
interest on the principal amount being prepaid to but excluding the date of
payment.

Notwithstanding any other provision of this Agreement, if after the date of this
Agreement any

change in applicable law or regulation or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof (whether or not having the force of
law) shall change the basis of taxation of payments to any Lender or the Issuing
Bank of the principal of or interest on any Eurodollar Loan made by such Lender
or any Fees or other amounts payable hereunder (other than changes in respect of
taxes imposed on the overall net income of such Lender or the Issuing Bank by
the jurisdiction in which such Lender or the Issuing Bank has its principal
office or by any political subdivision or taxing authority therein), or shall
impose, modify or deem applicable any reserve, special deposit or similar
requirement against assets of, deposits with or for the account of or credit
extended by any Lender or the Issuing Bank (except any such reserve requirement
that is fully reflected in the Adjusted LIBO Rate) or shall impose on such
Lender or the Issuing Bank or the London interbank market any other condition
affecting this Agreement or Eurodollar Loans made by such Lender or any Letter
of Credit or participation therein, and the result of any of the foregoing shall
be to increase the cost to such Lender or the Issuing Bank of making or
maintaining any Eurodollar Loan or increase the cost to any Lender of issuing or
maintaining any Letter of Credit or purchasing or maintaining a participation
therein or to reduce the amount of any sum received or receivable by such Lender
or the Issuing Bank hereunder (whether of principal, interest or otherwise) by
an amount deemed by such Lender or the Issuing Bank to be material, then the
Borrower shall pay to such Lender or the Issuing Bank, as the case may be, upon
demand such additional amount or amounts as shall compensate such Lender or the
Issuing Bank, as the case may be, for such additional costs incurred or
reduction suffered.

     (b) If any Lender or the Issuing Bank shall determine that the adoption
after the date of this Agreement of any law, rule, regulation, agreement or
guideline regarding capital adequacy, or any change after the date hereof in any
such law, rule, regulation, agreement or guideline (whether such law, rule,
regulation, agreement or guideline has been adopted) or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof, or compliance by any Lender (or any
lending office of such Lender) or the Issuing Bank or any Lender's or the
Issuing Bank's holding company with any request or directive regarding capital
adequacy (whether or not having the force
<PAGE>
 
                                                                              53

of law) of any Governmental Authority has or would have the effect of reducing
the rate of return on such Lender's or the Issuing Bank's capital or on the
capital of such Lender's or the Issuing Bank's holding company, if any, as a
consequence of this Agreement or the Loans made or participation's in Letters of
Credit purchased by such Lender pursuant hereto or the Letters of Credit issued
by the Issuing Bank pursuant hereto to a level below that which such Lender or
the Issuing Bank or such Lender's or the Issuing Bank's holding company could
have achieved but for such applicability, adoption, change or compliance (taking
into consideration such Lenders or the Issuing Bank's policies and the policies
of such Lender's or the Issuing Bank's holding company with respect to capital
adequacy) by an amount deemed by such Lender or the Issuing Bank to be material,
then from time to time the Borrower shall pay to such Lender or the Issuing
Bank, as the case may be, such additional amount or amounts as shall compensate
such Lender or the Issuing Bank or such Lender's or the Issuing Bank's holding
company for any such reduction suffered.

     (c) A certificate of a Lender or the Issuing Bank setting forth in
reasonable detail (i) the calculation of amount or amounts necessary to
compensate such Lender or the Issuing Bank or its holding company, as
applicable, as specified in paragraph (a) or (b) above and (ii) the facts and
circumstances giving rise to such compensation, shall be delivered to the
Borrower and shall be conclusive absent manifest error. The Borrower shall pay
such Lender or the Issuing Bank the amount shown as due on any such certificate
delivered by it within 10 Business Days after its receipt of the same.

     (d) Failure or delay on the part of any Lender or the Issuing Bank to
demand compensation for any increased costs or reduction in amounts received or
receivable or reduction in return on capital shall not constitute a waiver of
such Lender's or the Issuing Bank's right to demand such compensation; provided,
however, that neither any Lender nor the Issuing Bank may demand compensation
under this Section 2.14 for any period commencing earlier than 60 days prior to
such demand. The protection of this Section 2.14 shall be available to each
Lender and the Issuing Bank regardless of any possible contention of the
invalidity or inapplicability of the law, rule, regulation, agreement, guideline
or other change or condition that shall have occurred or been imposed; provided,
however, that each Lender and the Issuing Bank shall take reasonable actions
<PAGE>
 
                                                                              54

(which shall not require such Lender or the Issuing Bank to incur an
unreimbursed loss or unreimbursed cost or expense or otherwise take any action
precluded by legal or regulatory restrictions or suffer any disadvantage or
burden deemed by it to be significant) to avoid any need to claim compensation
under this Section 2.14 arising out of any reasonably foreseeable change in
circumstances.

     (e) Without prejudice to the survival of any other agreement contained
herein, the agreements and obligations contained in this Section 2.14 shall
survive the payment in full of the principal of and interest on all Loans made
hereunder, the expiration or cancellation of all Letters of Credit and the
reimbursement of all draws thereunder.

     SECTION 2.15. Change in Legality. (a) Notwithstanding any other provision
of this Agreement, if after the date of this Agreement, any change in any law or
regulation or in the interpretation thereof by any Governmental Authority
charged with the administration or interpretation thereof shall make it unlawful
for any Lender to make or maintain any Eurodollar Loan or to give effect to its
obligations as contemplated hereby with respect to any Eurodollar Loan, then, by
written notice to the Borrower and to the Administrative Agent:

          (i) such Lender may declare that Eurodollar Loans shall not thereafter
     (for the duration of such unlawfulness) be made by such Lender hereunder
     (or be continued for additional Interest Periods and ABR Loans will not
     thereafter (for such duration) be converted into Eurodollar Loans),
     whereupon any request for a Eurodollar Borrowing (or to convert an ABR
     Borrowing to a Eurodollar Borrowing or to continue a Eurodollar Borrowing,
     for an additional Interest Period) shall, as to such Lender only, be deemed
     a request for an ABR Loan (or a request to continue an ABR Loan as such for
     an additional Interest Period or to convert a Eurodollar Loan into an ABR
     Loan, as the case may be), unless such declaration shall be subsequently
     withdrawn; and

          (ii) such Lender may require that all outstanding Eurodollar Loans
     made by it be converted to ABR Loans, in which event all such Eurodollar
     Loans shall be automatically converted to ABR Loans as of the
<PAGE>
 
                                                                              55

     effective date of such notice as provided in paragraph (b) below (and
     Section 2.16 shall not apply to any such automatic conversion).

In the event any Lender shall exercise its rights under clause (i) or (ii)
above, all payments and prepayments of principal that would otherwise have been
applied to repay the Eurodollar Loans that would have been made by such Lender
or the converted Eurodollar Loans of such Lender shall instead be applied to
repay the ABR Loans made by such Lender in lieu of, or resulting from the
conversion of, such Eurodollar Loans.

     (b) For purposes of this Section 2.15, a notice to the Borrower by any
Lender shall be effective as to each Eurodollar Loan made by such Lender, if
lawful, on the last day of the Interest Period currently applicable to such
Eurodollar Loan; in all other cases such notice shall be effective on the date
of receipt by the Borrower.

     SECTION 2.16. Indemnity. The Borrower shall indemnify each Lender against
any loss or expense that such Lender may sustain or incur as a direct
consequence of (a) any event, other than a default by such Lender in the
performance of its obligations hereunder, which results in (i) such Lender
receiving or being deemed to receive any amount on account of the principal of
any Eurodollar Loan prior to the end of the Interest Period in effect therefor,
(ii) the conversion of any Eurodollar Loan to an ABR Loan, or the conversion of
the Interest Period with respect to any Eurodollar Loan, in each case other than
on the last day of the Interest Period in effect therefor, or (iii) any
Eurodollar Loan to be made by such Lender (including any Eurodollar Loan to be
made pursuant to a conversion or continuation under Section 2.10) not being made
after notice of such Loan shall have been given by the Borrower hereunder (any
of the events referred to in this clause (a) being called a "Breakage Event") or
(b) any default in the making of any payment or prepayment required to be made
hereunder. In the case of any Breakage Event, such loss shall include an amount
equal to the excess, as reasonably determined by such Lender, of (i) its cost of
obtaining funds for the Eurodollar Loan that is the subject of such Breakage
Event for the period from the date of such Breakage Event to the last day of the
Interest Period in effect (or that would have been in effect) for such Loan over
(ii) the amount of interest likely to be realized by such Lender in redeploying
the funds released or not utilized by reason of such

                                                                              56

Breakage Event for such period. A certificate of any Lender setting forth in
reasonable detail (i) the calculation of any amount or amounts which such Lender
is entitled to receive pursuant to this Section 2.16 and (ii) the facts and
circumstances giving rise to such entitlement, shall be delivered to the
Borrower (in the case of a claim under clause (a) above, within 60 days of the
applicable Breakage Event) and shall be conclusive absent manifest error.
Without prejudice to the survival of any other agreement contained herein, the
agreements and obligations contained in this Section 2.16 shall survive the
payment in full of the principal of and interest on all Loans made hereunder,
the expiration or cancellation of all Letters of Credit and the reimbursement of
all draws thereunder.

     SECTION 2.17. Pro Rata Treatment. Except as required under Section 2.15 and
subject to Section 9.06(b), each Borrowing, each payment or prepayment of
principal of any Borrowing, each payment of interest on the Loans, each payment
of the Commitment Fees, each reduction of Commitments and each refinancing of
any Borrowing with, conversion of any Borrowing to or continuation of any
Borrowing as a Borrowing of any Type shall be allocated pro rata among the
Lenders in accordance with their respective applicable Commitments (or, if such
Commitments shall have expired or been terminated, in accordance with the
respective principal amounts of their outstanding Loans). In computing any
Lender's portion of any Borrowing to be made hereunder, the Administrative Agent
may, in its discretion, round each Lender's percentage of such Borrowing to the
next higher or lower whole dollar amount.

     SECTION 2.18. Sharing of Setoffs. If any Lender shall, through the exercise
of a right of banker's lien, setoff or counterclaim against the Borrower, or
pursuant to a secured claim under Section 506 of Title 11 of the United States
Code or other security or interest arising from, or in lieu of, such secured
claim, received by such Lender under any applicable bankruptcy, insolvency or
other similar law or otherwise, or by any other means, obtain pavement
(voluntary or involuntary) in respect of any Loan or Loans or L/C Disbursement
as a result of which the unpaid principal portion of its Term Loans and
Revolving Loans and participations in L/C Disbursements shall be proportionately
less than the unpaid principal portion of the Term Loans and Revolving Loans and
participations in L/C Disbursements of any other Lender, it shall be deemed
simultaneously to have purchased from such other Lender at face value, and shall
<PAGE>
 
                                                                              57

promptly pay to such other Lender the purchase price for, a participation in the
Term Loans and Revolving Loans and L/C Exposure, as the case may be of such
other Lender, so that the aggregate unpaid principal amount of the Term Loans
and Revolving Loans and L/C Exposure and participations in Term Loans and
Revolving Loans and L/C Exposure held by each Lender shall be in the same
proportion to the aggregate unpaid principal amount of all Term Loans and
Revolving Loans and L/C Exposure then outstanding as the principal amount of its
Term Loans and Revolving Loans and L/C Exposure prior to such exercise of
banker's lien, setoff or counterclaim or other event was to the principal amount
of all Term Loans and Revolving Loans and L/C Exposure outstanding prior to such
exercise of banker's lien, setoff or counterclaim or other event; provided,
however, that if any such purchase or purchases or adjustments shall be made
pursuant to this Section 2.18 and the payment giving rise thereto shall
thereafter be recovered, such purchase or purchases or adjustments shall be
rescinded to the extent of such recovery and the purchase price or prices or
adjustment restored without interest. The Borrower expressly consents to the
foregoing arrangements and agrees that any Lender holding a participation in a
Term Loan or Revolving Loan or L/C Disbursement deemed to have been so purchased
may exercise any and all rights of banker's lien, setoff or counterclaim with
respect to any and all moneys owing by the Borrower to such Lender by reason
thereof as fully as if such Lender had made a Loan directly to the Borrower in
the amount of such participation.

     SECTION 2.19. Payments (a) Subject to Section 9.06(b), the Borrower shall
make each payment (including principal of or interest on any Borrowing or any
L/C Disbursement or any Fees or other amounts) hereunder and under any other
Loan Document not later than 1:00 p.m., New York City time, on the date when due
in immediately available dollars, without setoff, defense or counterclaim (but
without prejudice, waiver or effect of estoppel with respect to any defense or
counterclaim). Each such payment (other than Issuing Bank Fees, which shall be
paid directly to the Issuing Bank) shall be made to the Administrative Agent at
its offices at 270 Park Avenue, New York, New York.

     (b) Whenever any payment (including principal of or interest on any
Borrowing, any Fees or any other amounts) hereunder or under any other Loan
Document shall become due, or otherwise would occur, on a day that is not a
Business Day, such payment may be made on the next succeeding Busi-
<PAGE>
 
                                                                              58

ness Day, and such extension of time shall in such case be included in the
computation of interest or Fees, if applicable.

     SECTION 2.20. Taxes. (a) Any and all payments by the Borrower hereunder and
under any other Loan Document shall be made, in accordance with Section 2.19,
free and clear of and without deduction for any and all current or future taxes,
levies, imposts, deductions, charges or withholdings, and all liabilities with
respect thereto, excluding (i) income taxes imposed on the net income of the
Administrative Agent, any Lender or the Issuing Bank (or any transferee or
assignee thereof, including a participation holder (any such entity a
"Transferee")) and (ii) franchise taxes imposed on the net income of the
Administrative Agent, any Lender or the Issuing Bank (or Transferee), in each
case by the jurisdiction (A) under the laws of which the Administrative Agent,
such Lender or the Issuing Bank (or Transferee) is organized or any political
subdivision thereof or (B) in which the applicable lending office of the
Administrative Agent, such Lender or the Issuing Bank (or any Transferee) is
located or any political subdivision thereof (all such nonexcluded taxes,
levies, imposts, deductions, charges, withholdings and liabilities, collectively
or individually, being called "Taxes"). If the Borrower shall be required to
deduct any Taxes from or in respect of any sum payable hereunder or under any
other Loan Document to the Administrative Agent, any Lender or the Issuing Bank
(or any Transferee), (i) the sum payable shall be increased by the amount (an
"additional amount") necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
2.20) the Administrative Agent, such Lender or the Issuing Bank (or Transferee),
as the case may be, shall receive an amount equal to the sum it would have
received had no such deductions been made, (ii) the Borrower shall make such
deductions and (iii) the Borrower shall pay the full amount deducted to the
relevant Governmental Authority in accordance with applicable law.

     (b) In addition, the Borrower agrees to bear and shall pay to the relevant
Governmental Authority in accordance with applicable law any current or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies (including mortgage recording taxes and similar fees) that arise
from any payment made hereunder or under any other Loan Document or from the
execution, delivery or registration of, or otherwise with
<PAGE>
 
                                                                              59

respect to, this Agreement or any other Loan Document ("Other Taxes').

     (c) The Borrower shall indemnify the Administrative Agent, each Lender and
the Issuing Bank (or Transferee) for the full amount of Taxes and Other Taxes
paid by the Administrative Agent, such Lender or the Issuing Bank (or
Transferee), as the case may be, and any liability (including penalties,
interest and expenses (including reasonable attorney's fees and expenses))
arising therefrom or with respect thereto, whether or not such Taxes or Other
Taxes were correctly or legally asserted by the relevant Governmental Authority.
A certificate as to the amount of such payment or liability prepared by the
Administrative Agent, a Lender or the Issuing Bank (or Transferee), or the
Administrative Agent on its behalf, and setting forth in reasonable detail (i)
the calculation of and (ii) the facts and circumstances giving rise to such
payment or liability, absent manifest error, shall be final, conclusive and
binding for all purposes. Such indemnification shall be made within 30 days
after the date the Administrative Agent, any Lender or the Issuing Bank (or
Transferee), as the case may be, makes written demand therefor. Neither any
Lender nor the Issuing Bank (or Transferee) may make any claim for
indemnification more than 180 days after such Lender or the Issuing Bank (or
Transferee), as applicable, knows of the payment or liability with respect to
which such indemnification is to be sought (such 180 days to be reduced to 60
days if at the time of such claim for indemnification such Lender (or
Transferee) holds Loans or participations therein or the Issuing Bank has
outstanding Letters of Credit, as applicable).

     (d) If the Administrative Agent, a Lender or the Issuing Bank (or
Transferee) receives a refund in respect of any Taxes or Other Taxes as to which
it has been indemnified by the Borrower or with respect to which the Borrower
has paid additional amounts pursuant to this Section 2.20, it shall within 30
days from the date of such receipt pay over such refund to the Borrower (but
only to the extent of indemnity payments made, or additional amounts paid, by
the Borrower under this Section 2.20 with respect to the Taxes or Other Taxes
giving rise to such refund), net of all out-of-pocket expenses of the
Administrative Agent, such Lender or the Issuing Bank (or Transferee) and
without interest (other than interest paid by the relevant Governmental
Authority with respect to such refund); provided, however, that the Borrower,
upon the request of the Administrative
<PAGE>
 
                                                                              60

Agent, such Lender or the Issuing Bank (or Transferee), shall repay the amount
paid over to the Borrower (plus penalties, interest or other charges) to the
Administrative Agent, such Lender or the Issuing Bank (or Transferee) in the
event the Administrative Agent, such Lender or the Issuing Bank (or Transferee)
is required to repay such refund to such Governmental Authority.

     (e) As soon as practicable after the date of any payment of Taxes or Other
Taxes by the Borrower to the relevant Governmental Authority, the Borrower shall
deliver to the Administrative Agent, at its address referred to in Section 9.01,
the original or a certified copy of a receipt issued by such Governmental
Authority evidencing payment thereof.

     (f) Without prejudice to the survival of any other agreement contained
herein, the agreements and obligations contained in this Section 2.20 shall
survive the payment in full of the principal of and interest on all Loans made
hereunder, the expiration or cancellation of all Letters of Credit and the
reimbursement of all draws thereunder.

     (g) Each Lender (or Transferee) that is organized under the laws of a
jurisdiction other than the United States, any State thereof or the District of
Columbia (a "Non-U.S. Lender") shall deliver to the Borrower and the
Administrative Agent two copies of either United States Internal Revenue Service
Form 1001 or Form 4224, or, in the case of a Non-U.S. Lender claiming exemption
from U.S. Federal withholding tax under Section 871(h) or 881(c) of the Code
with respect to payments of "portfolio interest", Form W-8, or any subsequent
versions thereof or successors thereto (and, if such Non-U.S. Lender delivers a
Form W-8, certificate representing that such Non-U.S. Lender is not a bank for
purposes of Section 881(c) of the Code, is not a 10-percent shareholder (within
the meaning of Section 871(h)(3)(B) of the Code) of the Borrower and is not a
controlled foreign corporation related to the Borrower (within the meaning of
Section 864(d)(4) of the Code)), properly completed and duly executed by such
Non-U.S. Lender claiming complete exemption from, or reduced rate of, U.S.
Federal withholding tax on payments by the Borrower under this Agreement and the
other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender on
or before the date it becomes a party to this Agreement (or, in the case of a
Transferee that is a participation holder, on or before
<PAGE>
 
                                                                              61

the date such participation holder becomes a Transferee hereunder) and on or
before the date, if any, such Non-U.S. Lender changes its applicable lending
office by designating a different lending office (a "New Lending Office"). In
addition, each Non-U.S. Lender shall deliver such forms promptly upon the
obsolescence or invalidity of any form previously delivered by such Non-U.S.
Lender. Notwithstanding any other provision of this paragraph (g), a Non-U.S.
Lender shall not be required to deliver any form pursuant to this paragraph (g)
that such Non-U.S. Lender is not legally able to deliver.

     (h) The Borrower shall not be required to indemnify any Non-U.S. Lender or
to pay any additional amounts to any Non-U.S. Lender, in respect of United
States Federal withholding tax pursuant to paragraph (a) or (c) above to the
extent that (i) the obligation to withhold amounts with respect to United States
Federal withholding tax existed on the date such Non-U.S. Lender became a party
to this Agreement (or, in the case of a Transferee that is a participation
holder, on the date such participation holder became a Transferee hereunder) or,
with respect to payments to a New Lending Office, the date such Non-U.S. Lender
designated such New Lending Office with respect to a Loan; provided, however,
that this paragraph (h) shall not apply (x) to any Transferee or New Lending
Office that becomes a Transferee or New Lending Office as a result of an
assignment, participation, transfer or designation made at the request of the
Borrower and (y) to the extent the indemnity payment or additional amounts any
Transferee, or any Lender (or Transferee), acting through a New Lending Office,
would be entitled to receive (without regard to this paragraph (h)) do not
exceed the indemnity payment or additional amounts that the person making the
assignment, participation or transfer to such Transferee, or Lender (or
Transferee) making the designation of such New Lending Office, would have been
entitled to receive in the absence of such assignment, participation, transfer
or designation or (ii) the obligation to pay such additional amounts would not
have arisen but for a failure by such Non-U.S. Lender to comply with the
provisions of paragraph (g) above.

     (i) Nothing contained in this Section 2.20 shall require any Lender or the
Issuing Bank (or any Transferee) or the Administrative Agent to make available
any of its tax returns (or any other information that it deems to be
confidential or proprietary).

                                                                              62

     SECTION 2.21. Assignment of Commitments under Certain Circumstances; Duty
To Mitigate. (a) In the event (i) any Lender or the Issuing Bank delivers a
certificate requesting compensation pursuant to Section 2.14, (ii) any Lender or
the Issuing Bank delivers a notice described in Section 2.15, (iii) the Borrower
is required to pay any additional amount to any Lender or the Issuing Bank or
any Governmental Authority on account of any Lender or the Issuing Bank pursuant
to Section 2.20 or (iv) the Administrative Agent notifies the Borrower of any
Lender's failure to fund as provided in Section 2.02(d) or 2.02(f), the Borrower
may, at its sole expense and effort, upon notice to such Lender or the Issuing
Bank and the Administrative Agent, require such Lender or the Issuing Bank to
transfer and assign, without recourse (in accordance with and subject to the
restrictions contained in Section 9.04), all its interests, rights and
obligations under this Agreement to an assignee that shall assume such assigned
obligations (which assignee may be another Lender, if a Lender accepts such
assignment); provided, however, that (x) such assignment shall not conflict with
any law, rule or regulation or order of any court or other Governmental
Authority having jurisdiction, (y) the Borrower or such assignee shall have paid
to the affected Lender or the Issuing Bank in immediately available funds an
amount equal to the sum of the principal of the outstanding Loans and
participations in L/C Disbursements of such Lender or the Issuing Bank plus all
other amounts (excluding interest and Fees, which shall be paid when due to the
assigning Lender or the Issuing Bank under Sections 2.06 and 2.05, respectively)
accrued for the account of such Lender or the Issuing Bank hereunder (including
any amounts under Sections 2.14, 2.16 and 2.20) and (z) if prior to any such
transfer and assignment the circumstances or event that resulted in such
Lender's or the Issuing Bank's claim for compensation under Section 2.14 or
notice under Section 2.1 or the amounts paid pursuant to Section 2.20, as the
case may be, cease to cause such Lender or the Issuing Bank to suffer increased
costs or reductions in amounts received or receivable or reduction in return on
capital, or cease to have the consequences specified in Section 2.15, or cease
to result in amounts being payable under Section 2.20, as the case may be
(including as a result of any action taken by such Lender or the Issuing Bank
pursuant to paragraph (b) below), or if such Lender or the Issuing Bank shall
waive its right to claim further compensation under Section 2.14 in respect of
such circumstances or event or shall withdraw its notice under Section 2.15 or
shall waive its right to
<PAGE>
 
                                                                              63

further payments under Section 2.20 in respect of such circumstances or event or
shall fund as provided in Section 2.02(d) or 2.02(f), as the case may be, then
such Lender or the Issuing Bank shall not thereafter be required to make any
such transfer and assignment hereunder.

     (b) If (i) any Lender or the Issuing Bank shall request compensation under
Section 2.14, (ii) any Lender or the Issuing Bank delivers a notice described in
Section 2.15 or (iii) the Borrower is required to pay any additional amount to
any Lender or the Issuing Bank or any Governmental Authority on account of any
Lender or the Issuing Bank, pursuant to Section 2.20, then such Lender or the
Issuing Bank shall use reasonable efforts (which shall not require such Lender
or the Issuing Bank to incur an unreimbursable loss or unreimbursable cost or
expense or otherwise take any action inconsistent with its internal policies or
legal or regulatory restrictions or suffer any disadvantage or burden deemed by
it in good faith to be significant) (x) to file any certificate or document
reasonably requested in writing by the Borrower or (y) to assign its rights and
delegate and transfer its obligations hereunder to another of its offices,
branches or affiliates, if such filing or assignment would reduce its claims for
compensation under Section 2.14 or enable it to withdraw its notice pursuant to
Section 2.15 or would reduce amounts payable pursuant to Section 2.20, as the
case may be, in the future. The Borrower shall pay all reasonable costs and
expenses incurred by any Lender or the Issuing Bank in connection with any such
filing or assignment, delegation and transfer.

     SECTION 2.22. Letters of Credit. (a) General. The Borrower may request the
issuance, after the Merger Date, of a Letter of Credit, in a form reasonably
acceptable to the Administrative Agent and the Issuing Bank, appropriately
completed, for the account of the Borrower, at any time and from time to time
while the L/C Commitment remains in effect. This Section 2.22 shall not be
construed to impose an obligation upon the Issuing Bank to issue any Letter of
Credit that is inconsistent with the terms and conditions of this Agreement.

     (b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions.
In order to request the issuance of a Letter of Credit (or to amend, renew or
extend an existing Letter of Credit), the Borrower shall hand deliver or
telecopy to the Issuing Bank and the Administrative Agent (reasonably in advance
of the requested
<PAGE>
 
                                                                              64

date of issuance, amendment, renewal or extension) a notice requesting the
issuance of a Letter of Credit, or identifying the Letter of Credit to be
amended, renewed or extended, the date of issuance, amendment, renewal or
extension, the date on which such Letter of Credit is to expire (which shall
comply with paragraph (c) below), the amount of such Letter of Credit, the name
and address of the beneficiary thereof and such other information as shall be
necessary to prepare such Letter of Credit. Following receipt of such notice and
prior to the issuance of the requested Letter of Credit or the applicable
amendment, renewal or extension, the Administrative Agent shall notify the
Borrower and the Issuing Bank of the amount of the Aggregate Revolving Credit
Exposure after giving effect to (i) the issuance, amendment, renewal or
extension of such Letter of Credit, (ii) the issuance or expiration of any other
Letter of Credit that is to be issued or shall expire prior to the requested
date of issuance of such Letter of Credit and (iii) the borrowing or repayment
of any Revolving Credit Loans that (based upon notices delivered to the
Administrative Agent by the Borrower) are to be borrowed or repaid prior to the
requested date of issuance of such Letter of Credit. A Letter of Credit shall be
issued, amended, renewed or extended only if, and upon issuance, amendment,
renewal or extension of each Letter of Credit the Borrower shall be deemed to
represent and warrant that, after giving effect to such issuance, amendment,
renewal or extension (A) the L/C Exposure shall not exceed $30,000,000, and (B)
the Aggregate Revolving Credit Exposure shall not exceed the Total Revolving
Credit Commitment.

     (c) Expiration Date. Each Letter of Credit shall expire at the close of
business on the earlier of the date one year after the date of the issuance of
such Letter of Credit and the date that is five Business Days prior to the
Post-Merger Facilities Maturity Date, unless such Letter of Credit expires by
its terms on an earlier date.

     (d) Participations. By the issuance of a Letter of Credit and without any
further action on the part of the Issuing Bank or the Lenders, the Issuing Bank
hereby grants to each Lender, and each such Lender hereby acquires from the
applicable Issuing Bank, a participation in such Letter of Credit equal to such
Lender's Pro Rata Percentage of the aggregate amount available to be drawn under
such Letter of Credit, effective upon the issuance of such Letter of Credit. In
consideration and in furtherance of the foregoing, each Lender hereby absolutely
and unconditionally
<PAGE>
 
                                                                              65

agrees to pay to the Administrative Agent, for the account of the Issuing Bank,
in accordance with Section 2.02(f), such Lender's Pro Rata Percentage of each
L/C Disbursement made by the Issuing Bank and not reimbursed by the Borrower
forthwith on the date due as provided in paragraph (e) below. Each Lender
acknowledges and agrees that its obligation to acquire participations pursuant
to this paragraph (d) in respect of Letters of Credit is absolute and
unconditional and shall not be affected by any circumstance whatsoever,
including the occurrence and continuance of a Default or an Event of Default,
and that each such payment shall be made without any offset, abatement,
withholding or reduction whatsoever.

     (e) Reimbursement. If the Issuing Bank shall make any L/C Disbursement in
respect of a Letter of Credit, the Borrower shall pay the amount of such L/C
Disbursement to the Administrative Agent, for the account of the Issuing Bank,
not later than two hours after the Borrower shall have received notice from the
Issuing Bank that payment of such draft has been made, or, if the Borrower shall
have received such notice later than 10:00 a.m., New York City time, on any
Business Day, not later than 10:00 a.m., New York City time, on the immediately
following Business Day. The Borrower's obligations to reimburse L/C
Disbursements as provided in this paragraph (e) shall be absolute, unconditional
and irrevocable, and shall be performed strictly in accordance with the terms of
this Agreement, under any and all circumstances whatsoever, and irrespective of:

          (i) any lack of validity or enforceability of any Letter of Credit or
     any Loan Document, or any term or provision therein;

          (ii) any amendment or waiver of or any consent to departure from all
     or any of the provisions of any Letter of Credit or any Loan Document;

          (iii) the existence of any claim, setoff, defense or other right that
     the Borrower, any other party guaranteeing, or otherwise obligated with,
     the Borrower, any Subsidiary or other Affiliate thereof or any other person
     may at any time have against the beneficiary under any Letter of Credit,
     the Issuing Bank, the Administrative Agent or any Lender or any other
     person, whether in connection with this
<PAGE>
 
                                                                              66

     Agreement, any other Loan Document or any other related or unrelated
     agreement or transaction;

          (iv) any draft or other document presented under a Letter of Credit
     proving to be forged, fraudulent, invalid or insufficient in any respect or
     any statement therein being untrue or inaccurate in any respect;

          (v) payment by the Issuing Bank under a Letter of Credit against
     presentation of a draft or other document that does not comply with the
     terms of such Letter of Credit; and

          (vi) any other act or omission to act or delay of any kind of the
     Issuing Bank, the Lenders, the Administrative Agent or any other person or
     any other event or circumstance whatsoever, whether or not similar to any
     of the foregoing, that might, but for the provisions of this Section 2.22,
     constitute a legal or equitable discharge of the Borrower's obligations
     hereunder;

provided, however, that any payment by the Borrower under this paragraph (e)
shall be without prejudice to, and shall not have any effect of estoppel or
waiver with respect to, any claim of the Borrower against the Issuing Bank under
paragraph (f) below.

     (f) Liability of Issuing Bank. Without limiting the generality of paragraph
(e) above, it is expressly understood and agreed that the absolute and
unconditional obligation of the Borrower hereunder to reimburse L/C
Disbursements shall not be excused by the gross negligence or wilful misconduct
of the Issuing Bank. However, the foregoing shall not be construed to excuse the
Issuing Bank from liability to the Borrower to the extent of any direct damages
(as opposed to consequential damages, claims in respect of which are hereby
waived by the Borrower to the extent permitted by applicable law) suffered by
the Borrower that are caused by the Issuing Bank's gross negligence or wilful
misconduct in determining whether drafts and other documents presented under a
Letter of Credit comply with the terms thereof; it is understood that the
Issuing Bank may accept documents that appear on their face to be in order,
without responsibility for further investigation, regardless of any notice or
information to the contrary and, in making any payment under any Letter of
Credit, (i) the Issuing Bank's exclusive reliance on the documents presented to
it
<PAGE>
 
                                                                              67

under such Letter of Credit as to any and all matters set forth therein,
including reliance on the amount of any draft presented under such Letter of
Credit, whether or not the amount due to the beneficiary thereunder equals the
amount of such draft and whether or not any document presented pursuant to such
Letter of Credit proves to be insufficient in any respect, if such document on
its face appears to be in order, and whether or not any other statement or any
other document presented pursuant to such Letter of Credit proves to be forged
or invalid or any statement therein proves to be inaccurate or untrue in any
respect whatsoever and (ii) any noncompliance in any immaterial respect of the
documents presented under such Letter of Credit with the terms thereof shall, in
each case, be deemed not to constitute wilful misconduct or gross negligence of
the Issuing Bank.

     (g) Disbursement Procedures. The Issuing Bank shall, promptly following its
receipt thereof, examine all documents purporting to represent a demand for
payment under a Letter of Credit. The Issuing Bank shall as promptly as possible
give telephonic notification, confirmed by telecopy, to the Administrative Agent
and the Borrower of such demand for payment and whether the Issuing Bank has
made or will make an L/C Disbursement thereunder; provided, however, that any
failure to give or delay in giving such notice shall not relieve the Borrower of
its obligation to reimburse the Issuing Bank and the Lenders with respect to any
such L/C Disbursement. The Administrative Agent shall promptly give each Lender
notice thereof.

     (h) Interim Interest. If the Issuing Bank shall make any L/C Disbursement
in respect of a Letter of Credit, then, unless the Borrower shall reimburse such
L/C Disbursement in full on such date, the unpaid amount thereof shall bear
interest for the account of the Issuing Bank, for each day from and including
the date of such L/C Disbursement, to but excluding the earlier of the date of
payment or the date on which interest shall commence to accrue thereon at the
rate per annum that would apply to such amount if such amount were an ABR Loan.

     (i) Resignation or Removal of the Issuing Bank. The Issuing Bank may resign
at any time by giving 180 days' prior written notice to the Administrative
Agent, the Lenders and the Borrower, and may be removed at any time by the
Borrower by notice to the Issuing Bank, the Administrative Agent and the
Lenders. Subject to the next
<PAGE>
 
                                                                              68

succeeding paragraph, upon the acceptance of any appointment as the Issuing Bank
hereunder by a Lender that shall agree to serve as successor Issuing Bank, such
successor shall succeed to and become vested with all the interests, rights and
obligations of the retiring Issuing Bank and the retiring Issuing Bank shall be
discharged from its obligations to issue additional Letters of Credit hereunder.
At the time such removal or resignation shall become effective, the Borrower
shall pay all accrued and unpaid Fees pursuant to Section 2.05(c)(ii). The
acceptance of any appointment as the Issuing Bank hereunder by a successor
Lender shall be evidenced by an agreement entered into by such successor, in a
form satisfactory to the Borrower and the Administrative Agent, and, from and
after the effective date of such agreement, (i) such successor Lender shall have
all the rights and obligations of the previous Issuing Bank under this Agreement
and the other Loan Documents and (ii) references herein and in the other Loan
Documents to the term "Issuing Bank" shall be deemed to refer to such successor
or to any previous Issuing Bank, or to such successor and all previous Issuing
Banks, as the context shall require. After the resignation or removal of the
Issuing Bark hereunder, the retiring Issuing Bank shall remain a party hereto
and shall continue to have all the rights and obligations of an Issuing Bank
under this Agreement and the other Loan Documents with respect to Letters of
Credit issued by it prior to such resignation or removal, but shall not be
required to issue additional Letters of Credit.

     (j) Cash Collateralizatlon. If any Event of Default shall occur and be
continuing, the Borrower shall, on the Business Day it receives notice from the
Administrative Agent, deposit in an account with the Collateral Agent, for the
benefit of the Revolving Credit Lenders, an amount in cash equal to the L/C
Exposure as of such date. Such deposit shall be held by the Collateral Agent as
collateral for the payment and performance of the Obligations. The Collateral
Agent shall have exclusive dominion and control, including the exclusive right
of withdrawal, over such account. Other than any interest earned on the
investment of such deposits in Permitted Investments, which investments shall be
made at the option and sole discretion of the Collateral Agent, such deposits
shall not bear interest. Interest or profits, if any, on such investments shall
accumulate in such account. Moneys in such account shall (i) automatically be
applied by the Collateral Agent to reimburse the Issuing Bank for L/C
<PAGE>
 
                                                                              69

Disbursements for which it has not been reimbursed, (ii) be held for the
satisfaction of the reimbursement obligations of the Borrower for the L/C
Exposure at such time and (iii) if the maturity of the Loans has been
accelerated (but subject to the consent of Revolving Credit Lenders holding
participations in outstanding Letters of Credit representing greater than 50% of
the aggregate undrawn amount of all outstanding Letters of Credit), be applied
to satisfy the Obligations. If the Borrower is required to provide an amount of
cash collateral hereunder as a result of the occurrence of an Event of Default,
such amount (to the extent not applied as aforesaid) shall be returned, together
with any remaining interest, to the Borrower within two Business Days after all
Events of Default have been cured or waived.

                                   ARTICLE III

                         Representations and warranties

borrowings hereunder (collectively, the "Transactions") and the Acquisition (a)

<PAGE>
 
                                                                              70

any action by the stockholders of the Company to approve the Merger) and (b)
will not (i) violate (A) any provision of law, statute, rule or regulation, or
of the certificate or articles of incorporation or other constitutive documents
or by-laws of the Borrower or any Subsidiary, (B) any order of any Governmental
Authority or (C) any provision of any indenture, agreement or other instrument
to which the Borrower or any Subsidiary is a party or by which any of them or

breach of or constitute (alone or with notice or lapse of time or both) a
default under, or give rise to any right to accelerate or to require the

above) for such matters that, individually or in the aggregate, could not
reasonably be expected to have a Material Adverse Effect.

     SECTION 3.03. Enforceability. This Agreement has been duly executed and
delivered by the Borrower and constitutes, and each other Loan Document when
executed and delivered by each Loan Party thereto will constitute, a legal,
valid and binding obligation of such Loan Party enforceable against such Loan
Party in accordance with its terms, except as enforceability thereof may be
limited by bankruptcy, insolvency or similar laws of general application
affecting creditors' rights.

     SECTION 3.04. Governmental Approvals. No action, consent or approval of,

     SECTION 3.05. Financial Statements. (a) The Borrower has heretofore
furnished to the Lenders its consolidated balance sheets and statements of
income, shareholders' equity and cash flows (i) as of and for the fiscal year
ended December 31, 1994, audited by and accompanied by the opinion of BDO
Seidman, independent public accountants, and (ii) as of and for the fiscal
quarter and the portion of the fiscal year ended July 1, 1995, certified by a
Financial Officer. Such financial statements present fairly the financial
condition and results of operations of the Borrower and its consolidated
Subsidiaries as of such dates and for such periods. Such balance sheets and the
notes thereto disclose all material liabilities, direct or contingent, of the
Borrower and its consolidated Subsidiaries as of the dates thereof. Such
financial statements were prepared in accordance with GAAP applied on a
consistent basis, subject (in the case of the statements referred to in clause
(ii) above) to normal, year-end recurring adjustments.

     (b) The Borrower has heretofore furnished to the Lenders its unaudited pro
forma consolidated balance sheet as of July 1, 1995, and pro forma consolidated
income statement for the two fiscal quarters ended July 1, 1995, prepared giving
effect to the Transactions and the Acquisition as if they had occurred on July
1, 1995, and December 31, 1994, respectively. Such pro forma financial
statements have been prepared in good faith by the Borrower, based on the
assumptions used to prepare the pro forma financial information contained in the
Confidential Information Memorandum (which assumptions are believed by the
Borrower on the date hereof and on the Tender Offer Date to be reasonable), are
based on the best information available to the Borrower as of the date of
delivery thereof, accurately reflect all adjustments required to be made to give
effect to the Transactions and the Acquisition and present fairly on a pro forma
basis the estimated consolidated financial position of the Borrower and the
Subsidiaries as of July 1, 1995, and estimated consolidated results of
operations of the Borrower and the Subsidiaries for the two fiscal quarters
ended July 1, 1995, assuming that the Transactions and the Acquisition had
actually occurred at July 1, 1995, and December 31, 1994, respectively.

     (c) The Borrower has heretofore furnished to the Lenders the consolidated
balance sheets and statements of operations, stockholders' equity and cash flows
of the
<PAGE>
 
                                                                              72

Company (i) as of and for the fiscal year ended December 31, 1994, audited by
and accompanied by the opinion of Coopers & Lybrand LLP, independent public
accountants, and (ii) as of and for the fiscal quarter and the portion of the
fiscal year ended June 30, 1995. The Borrower has no knowledge that these
financial statements have not been prepared in accordance with GAAP applied on a
consistent basis (except to the extent set forth in those financial statements,
including the notes, if any) or do not present fairly in all material respects
the consolidated financial position of the Company as of their respective dates,
and the consolidated results of operations and changes in financial condition
and cash flows for the periods presented, subject, in the case of the unaudited
interim financial statements, to normal, recurring, year-end adjustments.

     SECTION 3.06. No Material Adverse Change. There has been no material
adverse change in the business, assets, operations, prospects or condition,
financial or otherwise, of the Borrower and the Subsidiaries, taken as a whole,
since December 31, 1994.

     SECTION 3.07. Title to Properties; Possession under Leases. (a) Each of the
Borrower and the Subsidiaries has good and marketable title to, or valid
leasehold interests in, all its material properties and assets (including all
Mortgaged Property). All such material properties and assets are free and clear
of Liens, other than Liens expressly permitted by Section 6.02, and no material
portion of any Mortgaged Property is subject to any lease, license, sublease or
other agreement granting to any person any right to use, occupy or enjoy such
portion.

     (b) Each of the Borrower and the Subsidiaries has complied with all
obligations under all material leases to which it is a party and all such leases
are in full force and effect. Each of the Borrower and the Subsidiaries enjoys
peaceful and undisturbed possession under all such material leases.

     (c) Neither the Borrower nor any Subsidiary has received any notice of, nor
has any knowledge of, any pending or contemplated condemnation proceeding
affecting the Mortgaged Properties or any sale or disposition thereof in lieu of
condemnation.

     (d) Neither the Borrower nor any Subsidiary is obligated under any right of
first refusal, option or other
<PAGE>
 
                                                                              73

contractual right to sell, assign or otherwise dispose of any Mortgaged Property
or any interest therein.

     SECTION 3.08. Subsidiaries. Schedule 3.08 sets forth as of the Tender Offer
Date a list of the Subsidiaries (other than the Company and its subsidiaries)
and the percentage ownership interest of the Borrower therein. The shares of
capital stock or other ownership interests so indicated on Schedule 3.08 are
fully paid and non-assessable and are owned by the Borrower, directly or
indirectly, free and clear of all Liens (other than Liens pursuant to the
Security Documents).

     SECTION 3.09. Litigation; Compliance with Laws. (a) Except as disclosed in
the Tender Offer Materials or the Company's Schedule 14D-9 with respect to the
Tender Offer, there are not any actions, suits or proceedings at law or in
equity or by or before any Governmental Authority now pending or, to the
knowledge of the Borrower, threatened against or affecting any Transaction Party
or any business, property or rights of any such person (i) that involve any Loan
Document, the Transactions or the Acquisition or (ii) as to which there is a
likelihood of an adverse determination and that, if adversely determined, could
reasonably be expected, individually or in the aggregate, to result in a
Material Adverse Effect.

     (b) None of the Borrower and the Subsidiaries or any of their respective
material properties or assets (including the Mortgaged Properties) is in
violation of, nor will the continued operation of such material properties and
assets as currently conducted violate, any law, rule or regulation (including
any Health Care Law, any Environmental Law, any zoning or building ordinance,
code or approval or any building permit) or any restriction of record or
agreements affecting the Mortgaged Property, or is in default with respect to
any judgment, writ, injunction, decree or order of any Governmental Authority,
other than, in each case, such violations and defaults that, individually and in
the aggregate, could not reasonably be expected to result in a Material Adverse
Effect.

     (c) Certificates of occupancy and material permits (or other documents
expressly provided for under applicable law in lieu thereof) are in effect for
each Mortgaged Property as currently constructed, and true and complete copies
of such certificates of occupancy have been

                                                                              74

delivered to the Collateral Agent as mortgagee with respect to each Mortgaged
Property.

     SECTION 3.10. Agreements. (a) Neither the Borrower nor any Subsidiary is a
party to any agreement or instrument or subject to any corporate restriction
that has resulted or could reasonably be expected to result in a Material
Adverse Effect.

     (b) Neither the Borrower nor any of the Subsidiaries is in default in any
manner under any provision of any indenture or other agreement or instrument
evidencing Indebtedness, the General Shareholders Agreement dated September 30,
1994, or any other agreement or instrument to which it is a party or by which it
or any of its properties or assets are or may be bound, other than such defaults
that, individually and in the aggregate, could not reasonably be expected to
result in a Material Adverse Effect.

     SECTION 3.11. Federal Reserve Regulations. (a) Neither the Borrower nor any
Subsidiary is engaged principally, or as one of its important activities, in the
business of extending credit for the purpose of buying or carrying Margin Stock.

     (b) No part of the proceeds of any Loan or any Letter of Credit will be
used, whether directly or indirectly, and whether immediately, incidentally or
ultimately, for any purpose that entails a violation of, or that is inconsistent
with, the provisions of the Regulations of the Board, including, to one extent
applicable, Regulation G, U or X. Margin Stocks do not constitute 25% or more of
the assets of the Borrower and the Subsidiaries, taken as a whole.

     (c) No Indebtedness of the Borrower or any Subsidiary (other than the
Obligations) is "directly or indirectly secured" (within the meaning of
Regulation U and Regulation G) by any Margin Stock.

     SECTION 3.12. Investment Company Act; Public Utility Holding Company Act.
Neither the Borrower nor any Subsidiary is (a) an "investment company" as
defined in, or subject to regulation under, the Investment Company Act of 1940,
(b) a "holding company" as defined in, or subject to regulation under, the
Public Utility Holding Company Act of
<PAGE>
 
                                                                              75

1935 or (c) otherwise subject to any law, rule or regulation that limits its
ability to incur Indebtedness.

     SECTION 3.13. Use of Proceeds. The Borrower will use the proceeds of the
Loans and will request the issuance of Letters of Credit only for the purposes
specified in the preamble to this Agreement.

     SECTION 3.14. Tax Returns. Each of the Borrower and the Subsidiaries has
filed or caused to be filed all Federal, state, local and foreign tax returns or
materials required to have been filed by it and has paid or caused to be paid
all taxes due and payable by it and all assessments received by it, except taxes
that are being contested in good faith by appropriate proceedings and for which
the Borrower or such Subsidiary, as applicable, shall have set aside on its
books (in accordance with GAAP accounting requirements) adequate reserves.

     SECTION 3.15. No Material Misstatements. (a) the Confidential Information
Memorandum or (b) information, report, financial statement, schedule authored
by, and furnished by or on behalf of, the Borrower in writing to the
Administrative Agent in connection with the negotiation of any Loan Document or
included therein or delivered pursuant thereto contains any material
misstatement of fact or omits to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they are made
misleading; provided, however, that to the extent any such information, report,
financial statement, exhibit or schedule was based upon or constitutes a
forecast or projection, the Borrower represents only that (x) it acted in good
faith and utilized reasonable assumptions and due care in the preparation of
such information, report, financial statement, exhibit or schedule and (y) with
respect to the projections contained in the Confidential Information Memorandum,
as of the date of this Agreement and as of the Closing Date, the Borrower
believes the assumptions underlying such projections are reasonable.

     SECTION 3.16. Employee Benefit Plans. Each of the Borrower and the ERISA
Affiliates is in compliance in all respects with the applicable provisions of
ERISA and the Code and the regulations and published interpretations thereunder,
except for such failures to comply that, individually and in the aggregate,
could not reasonably be expected to result in a Material Adverse Effect. No
ERISA
<PAGE>
 
                                                                              76

Event has occurred or is reasonably expected to occur that, when taken together
with all other such ERISA Events, could reasonably be expected to result in a
Material Adverse Effect. As of the date of this Agreement, none of the Plans is
a "defined benefit plan" as defined in Section 3(35) of ERISA or Section 414(j)
of the Code. The present value of all benefit liabilities under each Plan (based
on those assumptions used for purposes of Statement of Financial Accounting
Standards No. 87) did not, as of the last annual valuation date applicable
thereto, exceed by more than $15,000,000 the fair market value of the assets of
such Plan, and the present value of all benefit liabilities of all underfunded
Plans (based on those assumptions used for purposes of Statement of Financial
Accounting Standards No. 87) did not, as of the last annual valuation dates
applicable thereto, exceed by more than $15,000,000 the fair market value of the
assets of all such underfunded Plans.

     SECTION 3.17. Environmental Matters. (a) The properties owned or operated
by the Borrower and the Subsidiaries (the "Properties") do not contain any
Hazardous Materials in amounts or concentrations that constitute a violation of,
or could give rise to under, any Environmental Law, other than such violations
and liabilities that, individually and in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect.

     (b) The Properties and all operations of the Borrower and the Subsidiaries
are in compliance, and in the last six years have been in compliance, with all
Environmental Laws and all Environmental Permits have been obtained and are in
effect, other than such items that, individually and in the aggregate, could not
reasonably be expected to result in a Material Adverse Effect.

     (c) There have not been any Releases or threatened Releases at, from, under
or, to the knowledge of the Borrower, proximate to the Properties or otherwise
in connection with the operations of the Borrower or the Subsidiaries, which
Releases or threatened Releases, in the aggregate, could reasonably be expected
to result in a Material Adverse Effect.

     (d) Neither the Borrower nor any Subsidiary has received any notice of an
Environmental Claim in connection with the Properties or the operations of the
Borrower or the Subsidiaries or with regard to any person whose liabilities for
environmental matters the Borrower or the Subsidiaries
<PAGE>
 
                                                                              77

has retained or assumed, in whole or in part, contractually, or to the knowledge
of the Borrower by operation of law or otherwise, which, individually or in the
aggregate, could reasonably be expected to result in a Material Adverse Effect,
nor do the Borrower or the Subsidiaries have any knowledge that any such notice
is likely to be received or is being threatened.

     (e) Hazardous-Materials have not been transported from the Properties, nor
have Hazardous Materials been generated, treated, stored or disposed of at, on
or under any Property in a manner that could reasonably be expected to give rise
to any material liability under any Environmental Law, nor has the Borrower or
Subsidiary retained or assumed any liability, contractually, or to the knowledge
of the Borrower by operation of law or otherwise, with respect to the
generation, treatment, storage or disposal of Hazardous Materials, which
transportation, generation, treatment, storage or disposal, or retained or
assumed liabilities, individually or in the aggregate, could reasonably be
expected to result in a Material Adverse Effect.

     SECTION 3.18. Insurance. Schedule 3.18 sets forth a true, complete and
correct description of all insurance maintained by the Borrower or the
Subsidiaries as of the date hereof and the Closing Date. As of each such date,
such insurance is in full force and effect and all premiums due have been paid.
The Borrower and the Subsidiaries have insurance in such amounts and covering
such risks and liabilities as are in accordance with normal industry practice.

     SECTION 3.19. Solvency. (a) The fair salable value of the assets of the
Borrower and each Subsidiary exceeds and shall, immediately following each of
the Tender Offer Date and the Merger Date and the consummation of the related
financings, exceed the amount that will be required to be paid on or in respect
of the existing debts and other liabilities (including contingent liabilities)
of the Borrower or such Subsidiary as they mature.

     (b) The assets of the Borrower and each Subsidiary do not, and upon
consummation of the Acquisition will not, constitute unreasonably small capital
for the Borrower or such Subsidiary to carry out its business as now conducted
and as proposed to be conducted, including the capital needs of the Borrower or
such Subsidiary, taking
<PAGE>
 
                                                                              78

into account the particular capital requirements of the business conducted by
the Borrower and each Subsidiary, and the projected capital requirements and
capital availability thereof.

     (c) The Borrower and each Subsidiary do not intend to and shall not incur
debts beyond their respective ability to pay such debts as they mature taking
into account the timing and amounts of cash to be received by the Borrower and
such Subsidiary and of amounts to be payable on or in respect of obligations of
the Borrower and such Subsidiary. The cash flow of the Borrower and each
Subsidiary, after taking into account all anticipated uses of the cash of the
Borrower and each Subsidiary, will at all times be sufficient to pay all such
amounts on or in respect of debt of the Borrower or such Subsidiary when such
amounts are required to be paid.

     (d) The representations made in this Section 3.19 with respect to any
Subsidiary that is a Guarantor are made after taking into consideration and
giving effect to the Indemnity, Contribution and Subrogation Agreement.

     SECTION 3.20. Location of Real Property and Leased Premises. (a) Schedule
3.20(a) lists completely and correctly as of the date of this Agreement all real
property owned by the Borrower and the Subsidiaries and the addresses thereof
and, to the knowledge of the Borrower, all real property owned by the Company
and its subsidiaries as of the date of this Agreement and the addresses thereof.
The Borrower and the Subsidiaries own in all the real property set forth on
Schedule 3.20(a) as owned by the Borrower or any Subsidiary and, to the
knowledge of the Borrower, the Company and its subsidiaries own in fee all the
real property set forth on Schedule 3.20(a) as owned by the Company or any of
its subsidiaries.

     (b) Schedule 3.20(b) lists completely and correctly as of the date of this
Agreement all material real property leased by the Borrower and the Subsidiaries
and the addresses thereof and, to the knowledge of the Borrower, all real
property leased by the Company and its subsidiaries as of the date of this
Agreement and the addresses thereof. The Borrower and the Subsidiaries, as the
case may be, have valid leasehold interests in all the material real property
set forth on Schedule 3.20(b) as leased by the Borrower or any Subsidiary and,

     Agent, the Lenders, the Issuing Bank and their agents and employees; and

          (ii) the designation of any form, type or amount of insurance coverage

claims for labor, materials and supplies or otherwise that, if unpaid, might
give rise to a Lien upon such properties or any part thereof; provided, however,

obligation, tax, assessment, charge, levy or claim so long as the validity,
amount or entitlement thereof shall be contested in good faith by appropriate
proceedings and the Borrower shall have set aside on its books adequate reserves
with respect thereto in accordance with GAAP and such contest operates to
suspend enforcement of any related Lien and, in the case of a Mortgaged
Property, there is no material risk of forfeiture of such property.

     calculations showing compliance with Sections 6.13, 6.14, 6.15, 6.16, 6.17
     and 6.18 and the Interest Expense Coverage Ratio as of the end of such
     fiscal period;

          (d) promptly after the same become publicly available, copies of all
     periodic and other reports, proxy statements and other materials filed by
     the Borrower or any Subsidiary with the Securities and Exchange Commission,
     or any Governmental Authority succeeding to any or all of the functions of
     said Commission, or with any national securities exchange, or distributed
     to its shareholders, as the case may be;

account in which full, true and correct entries in conformity with GAAP and all
requirements of applicable law are made of all material dealings and
transactions in relation to its business. The Borrower will, and will cause each
Subsidiary to, permit any representatives designated by the Administrative Agent
or any Lender to visit and inspect the financial records and the properties of
the Borrower or any Subsidiary upon prior notice to a Financial Officer of the
Borrower, at mutually agreed times during normal business hours and as often as
reasonably requested and to make extracts from and copies of such financial
records (such visits and inspections to be coordinated, to the extent possible,
through the Administrative Agent). Permit any representatives designated by the
Administrative Agent or any Lender to discuss the affairs, finances and

(including filing Uniform Commercial Code and other financing statements,
mortgages and deeds of trust) that may be required under applicable law, or that

reasonably request, in order to effectuate the transactions contemplated by the
Loan Documents and in order to grant, preserve, protect and perfect the validity
and first priority of the security interests created or intended to be created
by the Security Documents. The Borrower shall cause any subsequently acquired or
organized Subsidiary to became a party to the Guarantee Agreement and the
Indemnity Subrogation and Contribution Agreement and each applicable Security
Document; provided, however, that no Foreign Subsidiary shall be required to
become a party to the Guarantee Agreement or to any Security Document. In
addition, from time to time, the Borrower shall, at its cost and expense,
promptly secure the Obligations by pledging or creating, or causing to be
pledged or created, perfected security interests with respect to such of its
assets and properties as the Administrative Agent or the Required Lenders shall
designate (it being understood that it is the intent of the parties that the
Obligations shall be secured by, among other things, substantially all the
assets of the Borrower and the Domestic Subsidiaries (including real and other
properties acquired subsequent to the Closing Date)). Such security interests
and Liens shall be created under the Security Documents and other security
agreements, mortgages, deeds of trust and other instruments and documents in
form and substance satisfactory to the Collateral Agent, and the Borrower shall
deliver or cause to be delivered to the Lenders all such instruments and
documents (including legal opinions, title insurance policies and lien searches)
as the Collateral Agent shall reasonably request to evidence compliance with
this Section 5.11. The Borrower shall provide such evidence as the Collateral
Agent shall reasonably request as to the perfection and priority status of each
such security interest and Lien.

of L/C Disbursements and all other amounts due to the Lenders hereunder, and
promptly to distribute to each Lender or the Issuing Bank its proper share of
each payment so received; (b) to give notice on behalf of each of the Lenders to
the Borrower of any Event of Default specified in this Agreement of which the
Administrative Agent has actual knowledge acquired in connection with its agency
hereunder; and (c) to distribute to each Lender copies of all notices, financial
statements and other materials delivered by the Borrower pursuant to this
Agreement as received by the Administrative Agent. Without limiting the
generality of the foregoing, the Agents are hereby expressly authorized to
execute any and all documents (including releases) with respect to the
Collateral and the rights of the Secured Parties with respect thereto, as
contemplated by and in accordance with the provisions of this Agreement and the
Security Documents.

     Each Lender specifically acknowledges the provisions of Section 9.06(b),
which provide that, under certain circumstances, payments otherwise due to a
Defaulting Lender need not be made. Each Lender further acknowledges that one of
the consequences of such provisions is that amounts received by the
Administrative Agent for the account of the Lenders may not be distributed on a
pro rata basis. The Administrative Agent shall be conclusively entitled to rely
on any notice furnished pursuant to Section 9.06(b), and neither the
Administrative Agent nor any of its directors, officers, employees or agents
shall be liable as such for any action taken or omitted by them as contemplated
or required by Section 9.06(b) or in reliance upon any such notice except to the
extent of its gross negligence or willful misconduct in determining whether any
notice under Section 9.06(b) on its face meets the requirements thereof. The
exculpation provided in the immediately preceding sentence shall be available
notwithstanding: (a) any dispute as to whether a Lender is a Defaulting Lender;
(b) any dispute as to whether a Default shall have occurred and be continuing;
(c) any dispute as to the amount of any Defaulted Advance; (d) any other dispute
as to the validity of any set-off under Section 9.06(b); or (e) the belief of
the Administrative Agent as to any of the foregoing matters.

     Neither the Agents nor any of their respective directors, officers,
employees or agents shall be liable as such for any action taken or omitted by
any of them except for its or his own gross negligence or willful misconduct, or
be responsible for any statement, warranty or representation herein or the
contents of any document delivered in connection herewith, or be required to
ascertain or to make any inquiry concerning the performance or observance by the
Borrower or any other Loan Party of any of the terms, conditions, covenants or
agreements contained in any Loan Document. The Agents shall not be responsible
to the Lenders for the due execution, genuineness, validity, enforceability or
effectiveness of this Agreement or any other Loan Documents, instruments or
agreements. The Agent shall in all cases be fully protected in acting, or
refraining from acting, in accordance with written instructions signed by the
Required Lenders and, except as otherwise specifically provided herein, such
instructions and any action or inaction pursuant thereto shall be binding on all
the Lenders. Each Agent shall, in the absence of knowledge to the contrary, be
entitled to rely on and instrument or document believed by it in good faith to
be genuine and correct and to have been signed or sent by the proper person or
persons. Neither the Agents nor any of their respective directors, officers,
employees or agents shall have any responsibility to the Borrower or any other
Loan Party on account of the failure of or delay in performance or breach by any
Lender or the Issuing Bank of any of its obligations hereunder or to any Lender
or the Issuing Bank on account of the failure of or delay in performance or
breach by any other Lender or the Issuing Bank or the Borrower or any other Loan
Parry of any or their respective obligations hereunder or under any other Loan
Document or in connection herewith or therewith. Each of the Agents may execute
any and all duties hereunder by or through agents or employees and shall be
entitled to rely upon the advice of legal counsel selected by it with respect to
all matters arising hereunder and shall not be liable for any action taken or
suffered in good faith by it in accordance with the advice of such counsel.

     The Lenders hereby acknowledge that neither Agent shall be under any duty
to take any discretionary action permitted to be taken by it pursuant to the
provisions of this Agreement unless it shall be requested in writing to do so by
the Required Lenders.

                                                                             115


     Subject to the appointment and acceptance of a successor Agent as provided
below, either Agent may resign at any time by notifying the Lenders and the
Borrower. Upon any such resignation, the Required Lenders shall have the right
to appoint a successor with the prior approval of the Borrower (such approval
not to be unreasonably withheld or delayed). If no successor shall have been so
appointed by the Required Lenders and shall have accepted such appointment
within 30 days after the retiring Agent gives notice of its resignation, then
the retiring Agent may, on behalf of the Lenders, appoint a successor Agent
which shall be a bank with an office in New York, New York, having a combined
capital and surplus of at least $500,000,000 or an Affiliate of any such bank.
Upon the acceptance of any appointment as Agent hereunder by a successor bank,
such successor shall succeed to and become vested with all the rights,
powers,privileges and duties of the retiring Agent and the retiring Agent shall
be discharged from its duties and obligations hereunder. After the Agent's
resignation hereunder, the provisions of this Article and Section 9.05 shall
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as Agent.

     With respect to the Loans made by it hereunder, each Agent in its
individual capacity and not as Agent shall have the same rights and powers as
any other Lender and may exercise the same as though it were not an Agent, and
the Agents and their Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with the Borrower or any Subsidiary or
other Affiliate thereof as if it were not an Agent.

     Each Lender agrees (a) to reimburse the Agents, on demand, in the amount of
its pro rata share (based on its Commitments hereunder) of any reasonable
out-of-pocket expenses incurred for the benefit of the Lenders by the Agents,
including counsel fees and compensation of agents and employees paid for
services rendered on behalf of the Lenders, that shall not have been reimbursed
by the Borrower and (b) to indemnify and hold harmless each Agent and any of its
directors, officers, employees or agents, on demand, in the amount of such pro
rata share, from and against any and all liabilities, taxes, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever that may be imposed on, incurred
by or asserted against it in its capacity as Agent or any of them in any way
relating to or

arising out of this Agreement or any other Loan Document or any action taken or
omitted by it or any of them under this Agreement or any other Loan Document, to
the extent the same shall not have been reimbursed by the Borrower, provided,
however, that no Lender shall be liable to an Agent or any such other
indemnified person for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the gross negligence or willful misconduct of such Agent or any
of its directors, officers, employees or agents. In the event any Agent is
subsequently reimbursed by any Loan Party for any such expenses, liabilities,
taxes, obligations, losses, damages, penalties, judgments, costs or
disbursements, such Agent shall reimburse each Lender, pro rata, to the extent
of any payment made by such Lender with respect thereto under this paragraph.

     Each Lender acknowledges that it has, independently and without reliance
upon the Agents or any other Lender and based on such documents and information
as it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement. Each Lender also acknowledges that it will, independently
and without reliance upon the Agents or any other Lender and based on such
documents and information as it shall from time to time deem appropriate,
continue to make its own decisions in taking or not taking action under or based
upon this Agreement or any other Loan Document, any related agreement or any
document furnished hereunder or thereunder.

making by the Lenders of the Loans and the issuance of Letters of Credit by the
Issuing Bank, regardless of any investigation made by the Lenders or the Issuing
Bank or on their behalf, and shall continue in full force and effect as long as
the principal of or any accrued interest on any Loan or any Fee or any other
amount payable under this Agreement or any other Loan Document is outstanding

     (b) Each Lender may assign to one or more assignees all or a portion of its
interests, rights and obligations under this Agreement (including all or a
portion of its Commitments and the Loans at the time owing to it); provided,
however, that (i) except in the case of an assignment to a Lender or an

the effective date specified in each Assignment and Acceptance, which effective
date shall be at least five Business Days after the execution thereof, (A) the
assignee thereunder shall be a party hereto and, to the extent of the interest
assigned by such Assignment and Acceptance, have the rights and obligations of a
Lender under this Agreement and (B) the assigning Lender thereunder shall, to
the extent of the interest assigned by such Assignment and Acceptance, be

be a party hereto but shall continue to be entitled to the benefits of Sections
2.14, 2.16, 2.20 and 9.05, as well as to any interest and Fees accrued for its
account and not yet paid).

     (c) By executing and delivering an Assignment and Acceptance, the assigning
Lender thereunder and the assignee thereunder shall be deemed to confirm to and
agree with each other and the other parties hereto as follows: (i) such
assigning Lender warrants that it is the legal and beneficial owner of the

                                                                             120


credit analysis and decision to enter into such Assignment and Acceptance; (v)
such assignee shall independently and without reliance upon the Administrative
Agent, the Collateral Agent, such assigning Lender or any other Lender and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement; (vi) such assignee appoints and authorizes the Administrative
Agent and the Collateral Agent to take such action as agent on its behalf and to
exercise such powers under this Agreement as are delegated to the Administrative
Agent and the Collateral Agent, respectively, by the terms hereof, together with
such powers as are reasonably incidental thereto; and (vii) such assignee agrees
that it shall perform in accordance with their terms all the obligations which
by the terms of this Agreement are required to be performed by it as a Lender.

     (d) The Administrative Agent, acting for this purpose as an agent of the
Borrower, shall maintain at one of its offices in The City of Net York a copy of
each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitment of,
and principal amount of the Loans owing to, each Lender pursuant to the terms
hereof from time to time (the "Register"). The entries in the Register shall be
conclusive and the Borrower, the Administrative Agent, the Issuing Bank, the
Collateral Agent and the Lenders may treat each person whose name is recorded in
the Register pursuant to the terms hereof as a Lender hereunder for all purposes
of this Agreement, notwithstanding notice to the contrary. The Register shall be
available for inspection by the Borrower, the Issuing Bank, the Collateral Agent
and any Lender, at any reasonable time and from time to time upon reasonable
prior notice.

     (e) Upon its receipt of a duly completed Assignment and Acceptance executed
by an assigning Lender and an assignee, an Administrative Questionnaire
completed in respect of the assignee (unless the assignee shall already be a
Lender hereunder), the processing and recordation fee referred to in paragraph
(b) above and, if required, the written consent of the Borrower, the Issuing
Bank and the Administrative Agent to such assignment, the Administrative Agent
shall (i) accept such Assignment and Acceptance, (ii) record the information
contained therein in the Register and (iii) give prompt notice thereof to the
Lenders and the Issuing Bank. No assignment shall be

                                                                             121


effective unless it has been recorded in the Register as provided in this
paragraph (e).

     (f) Each Lender may without the consent of the Borrower, the Issuing Bank
or the Administrative Agent sell participations to one or more banks or other
entities in all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Commitment and the Loans owing to it);
provided, however, that (i) such Lender's obligations under this Agreement shall
remain unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, (iii) each participating
bank or other entity shall be entitled to the benefit of the cost protection
provisions contained in Sections 2.14, 2.16 and 2.20 to the same extent as if it
were a Lender, but not in an amount greater than that of the Lender from which
it acquired its participation (and any entitlement thereto of such participant
shall reduce pro tanto the right of such Lender to claim the benefit of such
provisions), (iv) a participation may not be offered or sold to any
pharmaceutical company or to any Affiliate of a pharmaceutical company and (v)
the Borrower, the Administrative Agent, the Issuing Bank and the Lenders shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Agreement, and such Lender shall
retain the sole right to enforce the obligations of the Borrower relating to the
Loans or L/C Disbursements and to approve any amendment, modification or waiver
of any provision of this Agreement (other than amendments, modifications or
waivers decreasing any fees payable hereunder or the amount of principal of or
the rate at which interest is payable on the Loans, extending any scheduled
principal payment date or date fixed for the payment of interest on the Loans or
changing or extending the Commitments).

     (g) Notwithstanding Section 9.17, any Lender or participant may, in
connection with any assignment or participation or proposed assignment or
participation pursuant to this Section 9.04, disclose to the assignee or
participant or proposed assignee or participant any information relating to the
Borrower furnished to such Lender by or on behalf of the Borrower; provided,
however, that, prior to any such disclosure of information designated by the
Borrower as confidential, each such assignee or participant or proposed assignee
or participant shall execute an agreement (a copy of which shall be given to the
<PAGE>
 
                                                                             122


Borrower) whereby such assignee or participant shall agree to preserve the
confidentiality of such confidential information on terms no less restrictive
than those applicable to the Lenders pursuant to Section 9.17.

     (h) Any Lender may at any time assign all or any portion of its rights
under this Agreement or any note issued in connection herewith to a Federal
Reserve Bank to secure extensions of credit by such Federal Reserve Bank to such
Lender; provided, however, that no such assignment shall release a Lender from
any of its obligations hereunder or substitute any such Bank for such Lender as
a party hereto. In order to facilitate such an assignment to a Federal Reserve
Bank, the Borrower shall, at the request of the assigning Lender, duly execute
and deliver to the assigning Lender a promissory note or notes evidencing the
Loans made to the Borrower by the assigning Lender hereunder.

     (i) The Borrower shall not assign or delegate any of its rights or duties
hereunder without the prior written consent of the Administrative Agent, the
Issuing Bank and each Lender, and any attempted assignment without such consent
shall be null and void.

     (j) In the event that Standard & Poor's, Moody's Investors Service, Inc.,
and Thompson's BankWatch (or InsuranceWatch Ratings Service, in the case of
Lenders that are insurance companies (or Best's Insurance Reports, if such
insurance company is not rated by InsuranceWatch Ratings Service)) shall, after
the date that any Lender becomes a Lender, downgrade the long-term certificate
of deposit ratings of such Lender, and the resulting ratings shall be below
BBB-, Baa3 and C (or BE, in the case of a Lender that is an insurance company
(or B. in the case of an insurance company not rated by InsuranceWatch Ratings
Service)), then the Issuing Bank shall have the right, but not the obligation,
at its own expense, upon notice to such Lender and the Administrative Agent, to
replace (or to request the Borrower to use its reasonable efforts to replace)
such Lender with an assignee (in accordance with and subject to the restrictions
contained in paragraph (b) above), and such Lender hereby agrees to transfer and
assign without recourse (in accordance with and subject to the restrictions
contained in paragraph (b) above) all its interests, rights and obligations in
respect of its Revolving Credit Commitment to such assignee; provided, however,
that (i) no such assignment shall conflict with any
<PAGE>
 
                                                                             123


law, rule and regulation or order of any Governmental Authority and (ii) the
Issuing Bank or such assignee, as the case may be, shall pay to such Lender in
immediately available funds on the date of such assignment the principal of and
interest accrued to the date of payment on the Loans made by such Lender
hereunder and all other amounts accrued for such Lender's account or owned to it
hereunder.

     SECTION 9.05. Expenses; Indemnity. (a) The Borrower shall pay all
reasonable out-of-pocket expenses reasonably incurred by the Administrative
Agent, the Collateral Agent and the Issuing Bank in connection with the
syndication of the credit facilities provided for herein and the preparation and
administration of this Agreement and the other Loan Documents or in connection
with any amendments, modifications or waivers of the provisions hereof or
thereof) (whether or not the transactions hereby or thereby contemplated shall
be consummated) or incurred during the continuance of a Default by the
Administrative Agent, the Collateral Agent or any Lender in connection with the
enforcement or protection of its rights in connection with this Agreement and
the other Loan Documents or in connection with the Loans made or Letters of
Credit issued hereunder, including the reasonable fees, charges and
disbursements of Cravath, Swaine & Moore, counsel for the Administrative Agent
and the Collateral Agent, and, in connection with any such enforcement or
protection, the reasonable fees, charges and disbursements of any other counsel
for the Administrative Agent, the Collateral Agent or any Lender; provided,
however, that the Borrower shall not be required to pay for separate counsel for
the Administrative Agent and the Collateral Agent.

     (b) The Borrower shall indemnify the Administrative Agent, the Collateral
Agent, each Lender and the Issuing Bank, each Affiliate of any of the foregoing
persons and each of their respective directors, officers, employees and agents
(each such person being called an "Indemnitee") against, and hold each
Indemnitee harmless from, any and all losses, claims, damages, liabilities and
related expenses, including reasonable counsel fees, charges and disbursements,
incurred by or asserted against any Indemnitee arising out of, in any way
connected with, or as a result of (i) the execution or delivery of this
Agreement or any other Loan Document or any agreement or instrument contemplated
thereby, the performance by the parties thereto of their respective obligations
thereunder or the consummation of the Transactions and the other transactions
<PAGE>
 
                                                                             124


contemplated thereby (excluding, in the case of each Indemnitee other than
Chemical Bank and its Affiliates, legal expenses incurred prior to the date of
this Agreement), (ii) the use of the proceeds of the Loans or issuance of
Letters of Credit, (iii) any claim, litigation, investigation or proceeding
relating to any of the foregoing, whether or not any Indemnitee is a party
thereto, (iv) any actual or alleged presence or Release of Hazardous Materials
on any property owned or operated by the Borrower or any Subsidiary, or any
Environmental Claim related in any way to the Borrower or the Subsidiaries or
(v) in the case of the Administrative Agent, its Affiliates and each of their
respective directors, officers, employees and agents, any claims by any Lender
arising out of any exercise or attempted exercise by the Borrower of rights
under Section 9.06(b); provided, however, that such indemnity shall not, as to
any Indemnitee, be available to the extent that such losses, claims, damages,
liabilities or related expenses are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or willful misconduct of such Indemnitee (limited, in the case of
clause (v) above, to gross negligence or wilful misconduct in determining
whether any notice under Section 9.06(b) on its face meets the requirements
thereof).

     (c) The provisions of this Section 9.05 shall remain operative and in full
force and effect regardless of the expiration of the term of this Agreement, the
consummation of the transactions contemplated hereby, the repayment of any of
the Loans, the expiration of the Commitments, the expiration of any Letter of
Credit, the invalidity or unenforceability of any term or provision of this
Agreement or any other Loan Document, or any investigation made by or on behalf
of the Administrative Agent, the Collateral Agent, any Lender or the Issuing
Bank. All amounts due under this Section 9.05 shall be payable on written demand
therefor.

     SECTION 9.06. Rights of Setoff. (a) If an Event of Default shall have
occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender to or
for the credit or the account of the Borrower against any of and all the
obligations of the Borrower now or hereafter existing under this Agreement and
other Loan Documents held by such
<PAGE>
 
                                                                             125


Lender, irrespective of whether or not such Lender shall have made any demand
under this Agreement or such other Loan Document and although such obligations
may be unmatured. The rights of each Lender under this paragraph (a) are in
addition to other rights and remedies (including other rights of setoff) which
such Lender may have.

     (b) If, at any time, (i) any Lender shall be a Defaulting Lender and shall
owe a Defaulted Advance to the Borrower, (ii) no Default shall have occurred and
be continuing and neither the Required Lenders (determined without regard for
the proviso in the definition thereof) nor the Administrative Agent shall have
asserted in writing to the Borrower that a Default shall have occurred and be
continuing and (iii) the Borrower shall be required to make any payment
hereunder or under any Loan Document to or for the account of such Defaulting
Lender, then, unless the Borrower otherwise notifies the Administrative Agent,
the Borrower shall, to the fullest extent permitted by law, set off and apply
the amount of such payment against the Defaulted Advance. Prior to the due time
for any payment with respect to which the Borrower intends to exercise its
rights under this paragraph (b), the Borrower will deliver to the Administrative
Agent a notice signed by a Responsible Officer stating (A) that the conditions
set forth in clauses (i) and (ii) above are satisfied, (B) the amount of the
Defaulted Advance and the applicable Defaulting Lender and (C) the amount to be
set off.

     SECTION 9.07. Applicable Law. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS
(OTHER THAN LETTERS OF CREDIT AND AS EXPRESSLY SET FORTH IN OTHER LOAN
DOCUMENTS) SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE
STATE OF NEW YORK. EACH LETTER OF CREDIT SHALL BE GOVERNED BY, AND SHALL BE
CONSTRUED IN ACCORDANCE WITH, THE LAWS OR RULES DESIGNATED IN SUCH LETTER OF
CREDIT, OR IF NO SUCH LAWS OR ROLES ARE DESIGNATED, THE UNIFORM CUSTOMS AND
PRACTICE FOR DOCUMENTARY CREDITS (1993 REVISION), INTERNATIONAL CHAMBER OF
COMMERCE, PUBLICATION NO. 500 (THE "UNIFORM CUSTOMS") AND, AS TO MATTERS NOT
GOVERNED BY THE UNIFORM CUSTOMS, THE LAWS OF THE STATE OF NEW YORK.

     SECTION 9.08. Waivers; Amendment. (a) No failure or delay of the
Administrative Agent, the Collateral Agent, any Lender or the Issuing Bank in
exercising any power or right hereunder or under any other Loan Document shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such right or power, or any
<PAGE>
 
                                                                             126


abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Administrative Agent, the
Collateral Agent, the Issuing Bank and the Lenders hereunder and under the other
Loan Documents are cumulative and are not exclusive of any rights or remedies
that they would otherwise have. No waiver of any provision of this Agreement or
any other Loan Document or consent to any departure by the Borrower therefrom
shall in any event be effective unless the same shall be permitted by paragraph
(b) below, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. No notice or demand on
the Borrower in any case shall entitle the Borrower to any other or further
notice or demand in similar or other circumstances.

     (b) Neither this Agreement nor any provision hereof may be waived, amended
or modified except pursuant to an agreement or agreements in writing entered
into by the Borrower and the Required Lenders; provided, however, that no such
agreement shall (i) decrease the principal amount of, or extend the maturity of
or any scheduled principal payment date or date for the payment of any interest
on any Loan or any date for reimbursement of an L/C Disbursement, or waive or
excuse any such payment or any part thereof, or decrease the rate of interest on
any Loan or L/C Disbursement, without the prior written consent of each Lender
directly affected thereby, (ii) change or extend the Commitment or decrease the
Commitment Fees or L/C Participation Fees of any Lender or extend the time for
payment thereof without the prior written consent of such Lender, or (iii) amend
or modify the provisions of Section 2.16 or 9.04(i), the provisions of this
Section 9.08 or the definition of the term "Required Lenders" without the prior
written consent of each Lender, (iv) release all or a substantial part of the
Collateral, or release any Specified Guarantor, without the prior written
consent of Lenders having Loans, L/C Exposures and unused Revolving Credit and
Term Loan Commitments at such time representing at least 80% of the sum of all
Loans outstanding, L/C Exposures and unused Revolving Credit and Term Loan
Commitments at such time, or (v) amend, modify or otherwise affect the rights or
duties of the Administrative Agent, the Collateral Agent or the Issuing Bank
hereunder or under any other Loan Document without the prior written consent of
the Administrative Agent, the Collateral Agent or the Issuing Bank.

     SECTION 9.09. Interest Rate Limitation. Notwithstanding anything herein to
the contrary, if at any time the interest rate applicable to any Loan or
participation in any L/C Disbursement, together with all fees, charges and other
amounts which are treated as interest on such Loan or participation in such L/C
Disbursement under applicable law (collectively the "Charges"), shall exceed the
maximum lawful rate (the "Maximum Rate") which may be contracted for, charged,
taken, received or reserved by the Lender holding such Loan or participation in
accordance with applicable law, the rate of interest payable in respect of such
Loan or participation hereunder, together with all Charges payable in respect
thereof, shall be limited to the Maximum Rate and, to the extent lawful, the
interest and Charges that would have been payable in respect of such Loan or
participation but were not payable as a result or the operation of this Section
shall be cumulated and the interest and Charges payable to such Lender in
respect of other Loans or participations or periods shall be increased (but not
above the Maximum Rate therefor) until such cumulated amount, together with
interest thereon at the Federal Funds Effective Rate to the date of repayment,
shall have been received by such Lender.

     SECTION 9.10. Entire Agreement. This Agreement, the Fee Letter and the
other Loan Documents constitute the entire contract between the parties relative
to the subject matter hereof. Any other previous agreement among the parties
with respect to the subject matter hereof is superseded by this Agreement and
the other Loan Documents. Nothing in this Agreement or in the other Loan
Documents, expressed or implied, is intended to confer upon any party other than
the parties hereto and thereto any rights, remedies, obligations or liabilities
under or by reason of this Agreement or the other Loan Documents.

     SECTION 9.11. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER
OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS. EACH
PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY
OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B)
ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS APPLICABLE, BY, AMONG

OTHER THINGS, THE  MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.11.

     SECTION 9.12. Severability. In the event any one or more of the provisions
contained in this Agreement or in any other Loan Document should be held
invalid, illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein and therein shall
not in any way be affected or impaired thereby. The parties shall endeavor in
good-faith negotiations to replace the invalid, illegal or unenforceable
provisions with valid provisions the economic effect of which comes as close as
possible to that of the invalid, illegal or unenforceable provisions.

     SECTION 9.13. Counterparts. This Agreement may be executed in counterparts
(and by different parties hereto on different counterparts), each of which shall
constitute an original but all of which when taken together shall constitute a
single contract, and shall become effective as provided in Section 9.03.
Delivery of an executed signature page to this Agreement by facsimile
transmission shall be as effective as delivery of a manually signed counterpart
of this Agreement.

     SECTION 9.14. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

     SECTION 9.15. Jurisdiction; Consent to Service of Process. (a) Each party
hereto hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction o
f any New York State court or
Federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement or the other Loan Documents, or for recognition or
enforcement of any judgment, and each party hereto hereby irrevocably and
unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. Each party hereto agrees that a final
judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Nothing in this Agreement shall affect any

                                                                             129


right that the Administrative Agent, the Collateral Agent, the Issuing Bank or
any Lender may otherwise have to bring any action or proceeding relating to this
Agreement or the other Loan Documents against the Borrower or its properties in
the courts of any jurisdiction.

     (b) Each party hereto hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement or the other Loan Documents in any
New York State or Federal court. Each party hereto hereby irrevocably waives, to
the fullest extent permitted by law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court.

     (c) Each party hereto irrevocably consents to service of process in the
manner provided for notices in Section 9.01. Nothing in this Agreement will
affect the right of any party to this Agreement to serve process in any other
manner permitted by law.

     SECTION 9.16. Mortgaged Property Casualty and Condemnation. (a)
Notwithstanding any other provision of this Agreement or the Security Documents,
the Collateral Agent is authorized, at its option (for the benefit of the
Secured Parties), to collect and receive, to the extent payable to the Borrower
or any other Loan Party, all insurance proceeds, damages, claims and rights of
action under any insurance policies with respect to any casualty or other
insured damage ("Casualty") to any portion of any Mortgaged Property
(collectively "Insurance Proceeds"), unless the amount of the related Insurance
Proceeds is less than $1,000,000 and an Event of Default shall not have occurred
and be continuing. The Borrower shall notify the Collateral Agent and the
Administrative Agent, in writing, promptly after the Borrower or any Subsidiary
obtains notice or knowledge of any Casualty to a Mortgaged Property, which
notice shall set forth a description of such Casualty and the Borrower's good
faith estimate of the amount of related damages. The Borrower shall, subject to
the foregoing limitations, endorse and transfer or cause to be endorsed or
transferred any Insurance Proceeds received by it or any other Loan Party to the
Collateral Agent.

     (b) In the event of any Casualty of less than or equal to 50% of the
useable square footage of the
<PAGE>
 
                                                                             130


improvements of any Mortgaged Property, the Borrower shall, subject to the
conditions contained in paragraph (f) below, restore such Mortgaged Property to
substantially its same condition immediately prior to such Casualty. In the
event of any Casualty of greater than 50% of the useable square footage of the
improvements of any Mortgaged Property and so long as no Default or Event of
Default has occurred and is continuing, the Borrower shall have the option to:

          (i) subject to the conditions contained in paragraph (f) below,
     restore such Mortgaged Property to a condition substantially similar to its
     condition immediately prior to such Casualty and to invest the balance, if
     any, of any Insurance Proceeds in equipment or other assets used in the
     Borrower's principal lines of business within 20 months after the receipt
     thereof, provided that the Borrower, pending such reinvestment, promptly
     deposits such excess Insurance Proceeds in a cash collateral account
     established with the Collateral Agent for the benefit of the Secured
     Parties,

          (ii) replace such Mortgaged Property with property of utility
     comparable to that of the replaced Mortgaged Property and to invest the
     balance, if any, of any Insurance Proceeds, in equipment, vehicles or other
     assets used in the Borrowers principal lines of business within 20 months
     after the receipt thereof, provided that the Borrower, pending such
     reinvestment, promptly deposits such excess Insurance Proceeds in a cash
     collateral account established with the Collateral Agent for the benefit of
     the Secured Parties, or

          (iii) apply the related Insurance Proceeds to (after reimbursement of
     the reasonable costs, if any, incurred by the Collateral Agent in
     connection with such Casualty) prepay Loans (in the order set forth in
     Section 2.13(d)).

Any Insurance Proceeds on account of damage to fixed assets, fixtures, plant or
equipment that are not applied to restore or replace such Mortgaged Property or
reinvested in the Borrower's principal lines of business as contemplated above
shall be applied (after reimbursement of the reasonable costs, if any, incurred
by the Collateral Agent in connection with such Casualty) to prepay Loans (in
the order set forth in Section 2.13(d)).
<PAGE>
 
                                                                             131


     (c) If required to do so, the Borrower shall make the election contemplated
by paragraph (b) above by notifying the Collateral Agent and the Administrative
Agent promptly after the later to occur of (i) 10 Business Days after the
Borrower and its insurance carrier reach a final determination of the amount of
any Insurance Proceeds and (ii) 90 days after the occurrence of the Casualty. If
the Borrower shall be required or shall elect to restore the Mortgaged Property,
the insufficiency of any Insurance Proceeds to defray the entire expense of such
restoration shall in no way relieve the Borrower of such obligation so to
restore. In the event the Borrower shall be required to restore or shall notify
the Collateral Agent and the Administrative Agent of its election to restore,
the Borrower shall diligently and continuously prosecute the restoration of the
Mortgaged Property to completion. In the event of a Casualty where the Borrower
is required to make the election set forth in paragraph (b) above and the
Borrower shall fail to notify the Collateral Agent and the Administrative Agent
of its election within the period set forth above or shall elect not to restore
the Mortgaged Property, the Borrower shall apply such Insurance Proceeds (after
reimbursement of all reasonable costs incurred by the Collateral Agent in
connection with the applicable Casualty) to prepay Loans (in the order set forth
in Section 2.13(d)). In addition, upon such prepayment, the Borrower shall be
obligated to place the remaining portion, if any, of the Mortgaged Property in a
safe condition that is otherwise in compliance with the requirements of
applicable Governmental Authorities and the provisions of this Agreement and the
applicable Mortgage.

     (d) The Borrower shall notify the Collateral Agent and the Administrative
Agent immediately upon obtaining knowledge of the institution of any action or
proceeding for the taking of any Mortgaged Property, or any part thereof or
interest therein, for public or quasi-public use under the power of eminent
domain, by reason of any public improvement or condemnation proceeding, or in
any other manner (a "Condemnation"). No settlement or compromise of any claim in
connection with any such action or proceeding shall be made without the consent
of the Collateral Agent, which consent shall not be unreasonably withheld. The
Collateral Agent is authorized, at its option (for the benefit of the Secured
Parties), to collect and receive, for application in accordance with paragraphs
(e) and (f) below, all proceeds of any such Condemnation (in each case, the
"Condemnation Proceeds"), unless the amount
<PAGE>
 
                                                                             132


of the related Condemnation Proceeds is less than $1,000,000 and an Event of
Default shall not have occurred and be continuing. The Borrower shall execute or
cause to be executed such further assignments of any Condemnation Proceeds as
the Collateral Agent may reasonably require.

     (e) In the event of any Condemnation of the Mortgaged Property or any part
thereof, and subject to paragraph (f) below, the Borrower shall apply any
Condemnation Proceeds first, in the case of a partial Condemnation, to the
repair or restoration of any integrated structure subject to such Condemnation
or, in the case of a total Condemnation or a Condemnation of substantially all a
Mortgaged Property (a "substantially all" Condemnation), to the location of a
replacement property, acquisition of such replacement property and construction
of the replacement structures, and second, shall apply the remainder of such
Condemnation Proceeds (after reimbursement of the reasonable costs, if any,
incurred by the Collateral Agent in connection with such Condemnation) to prepay
Loans (in the order set forth in Section 2.13(d)).

     (f) Except as otherwise specifically provided in this Section 9.16, all
Insurance Proceeds (other than Insurance Proceeds arising out of any Casualty
but not on account of damage to fixed assets, fixtures, plant or equipment) and
all Condemnation Proceeds (i) are to be applied to the restoration of the
applicable Mortgaged Property (after reimbursement of the reasonable costs, if
any, incurred by the Collateral Agent in connection with the applicable Casualty
or Condemnation, including reasonable attorneys' fees, other charges and
disbursements and costs allocable to inspecting the Work (as defined below)) and
(ii) shall be applied to the payment of the cost of restoring or replacing the
Mortgaged Property so damaged, destroyed or taken or of the portion or portions
of the Mortgaged Property not so taken (the "Work") and (iii) shall be paid out
from time to time to the Borrower as and to the extent the Work (or the location
and acquisition of any replacement of any Mortgaged Property) progresses for the
payment thereof, but subject to each of the following conditions:

               (A) the Borrower must promptly commence the restoration process
          or the location, acquisition and replacement process in connection
          with the Mortgaged Property;
<PAGE>
 
                                                                             133


               (B) the Work shall be in the charge of an architect or engineer
          and before the Borrower commences any Work, other than temporary work
          to protect property or prevent interference with business, the
          Collateral Agent shall have received the plans and specifications and
          the general contract for the Work from the Borrower (which plans and
          specifications shall provide for such Work that, upon completion
          thereof, the improvements shall (x) be in compliance with all
          requirements of applicable Governmental Authorities such that all
          representations and warranties of the Borrower relating to the
          compliance of such Mortgaged Property with applicable laws, rules or
          regulations in this Agreement or the Security Documents shall be
          correct in all respects and (y) be at least equal in value and general
          utility to the improvements that were on such Mortgaged Property (or
          that were on the Mortgaged Property that has been replaced, if
          applicable) prior to the Casualty or Condemnation, and in the case of
          a Condemnation, subject to the effect of such Condemnation;

               (C) except as provided in clause (D) below, each request for
          payment shall be made on seven days' prior notice to the Collateral
          Agent and shall be accompanied by a certificate to be made by a
          Responsible Officer of the Borrower, stating (x) that all the Work
          completed has been done in substantial compliance with the plans and
          specifications and (y) that the sum requested is justly required to
          reimburse the Borrower for payments by the Borrower to, or is justly
          due to, the contractor, subcontractors, materialmen, laborers,
          engineers, architects or other persons rendering services or materials
          for the Work (giving a brief description of such services and
          materials) and that, when added to all sums previously paid out by the
          Collateral Agent, does not exceed the value of the Work done to the
          date of such certificate;

               (D) each request for payment in connection with the acquisition
          of a replacement Mortgaged Property shall be made on 30 days' prior
          notice to the Collateral Agent and, in connection therewith, (x) each
          such request shall be accompanied by a copy of the sales contract or
          other document governing the acquisition of the replacement property
          by the Borrower and a certificate of the Borrower stating that the sum
          requested represents the sales price under such contract or document
          and the related reasonable
<PAGE>
 
                                                                             134


          transaction fees and expenses (including brokerage fees) and setting
          forth in sufficient detail the various components of such requested
          sum and (y) the Borrower shall (I) in addition to any other items
          required to be delivered under this Section 9.16), provide the
          Administrative Agent and the Collateral Agent with such opinions,
          documents, certificates, title insurance policies, surveys and other
          insurance policies as they may reasonably request and (II) take such
          other actions as the Administrative Agent and the Collateral Agent may
          reasonably deem necessary or appropriate (including actions with
          respect to the delivery to the Collateral Agent of a first priority
          Mortgage with respect to such real property for the ratable benefit of
          the Secured Parties);

               (E) there shall be no Default or Event of Default that has
          occurred and is continuing (other than any Default or Event of Default
          arising out of such Casualty or Condemnation);

               (F) the request for any payment after the Work has been completed
          shall be accompanied by a copy of any certificate or certificates
          required by law to render occupancy of the improvements being rebuilt,
          repaired or restored legal; and

               (G) after commencing the Work, the Borrower shall continue to
          perform the Work diligently and in good faith to completion in
          accordance with the approved plans and specifications.

     (g) Notwithstanding any other provisions of this Section 9.16, if the
Borrower shall have elected to replace a Mortgaged Property in connection with a
total or "substantially all" Condemnation as contemplated in paragraph (e)
above, all Condemnation Proceeds held by the Collateral Agent in connection
therewith shall be applied to prepay Loans (in the order set forth in Section
2.13(d)) if (i) the Borrower notifies the Collateral Agent and the
Administrative Agent that it does not intend to replace the related Mortgaged
Property, (ii) a Responsible Officer of the Borrower shall not have notified the
Administrative Agent and the Collateral Agent in writing that the Borrower has
acquired or has entered into a binding contract to acquire land upon which it
will construct the replacement property within six months after the related
Condemnation or (iii) the Borrower shall have not have begun construction of
<PAGE>
 
                                                                             135

the replacement structures within one year after the related Condemnation and
the principal reason for such failure to begin construction is the failure of
the Borrower to diligently pursue the replacement of the related Mortgaged
Property.

     (h) Any amounts held by the Collateral Agent pursuant to this Section 9.16
shall be held as collateral for the payment and performance of the Obligations.
Except as otherwise expressly specified in this Section 9.16, the Collateral
Agent shall have exclusive dominion and control, including the exclusive right
of withdrawal, over such amounts. At the option of the Collateral Agent, such
amounts may be invested in Permitted Investments (in which event interest
thereon shall be added to such amounts and be subject to this Section 9.16) or,
if the Borrower so directs, used to prepay Revolving Credit Borrowings (in which
event any reborrowing of such amounts shall be applied in accordance with this
Section 9.16). Except as provided in the preceding sentence, such amounts shall
not bear interest. Nothing in this Section 9.16 shall prevent the Collateral
Agent from applying at any time all or any part of the Insurance Proceeds or
Condemnation Proceeds to the curing of any Event of Default under this
Agreement.

     (i) Any Insurance Proceeds not on account of damage to fixed assets,
fixtures, plant or equipment need not be applied to restoration, repair or the
prepayment of Loans and, if received by the Collateral Agent, shall promptly be
paid over to the Borrower unless an Event of Default shall be continuing.

     SECTION 9.17. Confidentiality . The Administrative Agent, the Collateral
Agent, the Issuing Bank and each of the Lenders agrees to keep confidential (and
to use its best efforts to cause its respective agents and representatives to
keep confidential) the Information (as defined below) and all copies thereof,
extracts therefrom and analyses or other materials based thereon, except that
the Administrative Agent, the Collateral Agent, the Issuing Bank or any Lender
shall be permitted to disclose Information (a) to such of its respective
officers, directors, employees, agents, affiliates and representatives as need
to know such Information, (b) to the extent requested by any regulatory
authority, (c) to the extent otherwise required by applicable laws and
regulations or by any subpoena or similar legal process, upon prior notice
thereof (unless prohibited by the terms of such subpoena or process) to the
<PAGE>
 
                                                                             136

Borrower in a manner reasonably calculated to afford the Borrower an opportunity
to seek a protective order or other injunctive relief, (d) in connection with
any suit, action or proceeding relating to the enforcement or protection of its
rights hereunder or under the other Loan Documents or (e) to the extent such
Information (i) becomes publicly available other than as a result of a breach of
this Section 9.17 or (ii) becomes available to the Administrative Agent, the
Issuing Bank, any Lender or the Collateral Agent on a nonconfidential basis from
a source other than the Borrower. For the purposes of this Section 9.17,
"Information" stall mean all financial statements, certificates, reports,
agreements and information (including all analyses, compilations and studies
prepared by the Administrative Agent, the Collateral Agent, the Issuing Bank or
any Lender based on any of the foregoing) that are received from the Borrower
and related to the Borrower, any shareholder of the Borrower or any employee,
customer or supplier of the Borrower, other than any of the foregoing that were
available to the Administrative Agent, the Collateral Agent, the Issuing Bank or
any Lender on a nonconfidential basis prior to its disclosure thereto by the
Borrower, and which are in the case of Information provided after the date
hereof, clearly identified at the time of delivery as confidential. The
provisions of this Section 9.17 shall remain operative and in full force and
effect regardless of the expiration and term of this Agreement.

                              (in such capacity, the "Collateral Agent") for the

              Amendments to and Waivers under the Credit Agreement

     The Credit Agreement is amended, effective as of the date hereof (but

     terms (including, without limitation, maturity, interest rates,
     subordination provisions, prepayment, redemption, defeasance or similar
     provisions, covenants and events of default) at least as favorable in all

     Indenture), or any combination thereof, in either case yielding net cash
     proceeds to the Borrower of at least $96,000,000, and (b) applies such net

<PAGE>
 
                                                                               3

          "'Conversion Note Indenture' shall mean the "Conversion Note
     Indenture" referred to in the Senior Subordinated Loan Agreement, in the
     form attached as Annex I-B to the Third Amendment."

          "'Refinancing Debt' shall have the meaning assigned to such term in
     Section 6.01(g)."

          "'Senior Subordinated Loan Agreement' shall mean the $100,000,000

          "'Third Amendment' shall mean the Third Amendment dated as of December
     20, 1996, to this Agreement."

     (b) The definition of "Subordinated Debt" is amended to read as follows:

          "'Subordinated Debt' means unsecured Indebtedness of the Borrower that
     (a) does not have any scheduled payment of principal prior to the 180th day
     following the Post-Merger Facilities Maturity Date, (b) the principal of
     which is subordinated to the prior payment in full in cash of all the
     Obligations in a manner reasonably satisfactory to the Administrative Agent
     and (c) otherwise has terms and conditions reasonably satisfactory to the
     Administrative Agent. Notwithstanding any other provision of this
     Agreement, Subordinated Debt shall include (i) Indebtedness incurred under
     and on the terms set forth in the Senior Subordinated Loan Agreement or the
     Conversion Note Indenture, and (ii) Refinancing Debt; provided that the
     terms of such Refinancing Debt (including, without limitation, maturity,
     interest rates, subordination provisions, prepayment, redemption,
     defeasance or similar provisions, covenants and events of default) shall be
     in all material respects at least as favorable to the Borrower and the
     Lenders as the terms of the Indebtedness being refinanced, or, in the case
     of interest rates, shall be consistent with rates of interest at the time
     prevailing in the market for comparable obligations (or, if the
     Indebtedness being refinanced was incurred under the Senior Subordinated
     Loan Agreement or the Conversion Note Indenture, at least as favorable to
     the Borrower and the Lenders as the terms of the Indebtedness issued (or
     that would have been issued) under the Conversion Note Indenture including,
     without limitation, the interest rate provided for in the form of Senior
     Subordinated Conversion Note annexed as Exhibit B thereto)."

     SECTION 2.02 Amendments to Article II. (a) Section 2.11(b) of the Credit
Agreement is amended by (i) inserting the phrase "(other than Section 2.13(f))"
between "2.13" and "shall" and (ii) inserting the following at the end of the
second sentence following the word "prepayment":

          ", and each prepayment of principal of Term Facility Borrowings

                                                                               4

     in full the amounts due on or prior to June 30, 1998, in order of maturity
     and (B) second, to reduce pro rata the scheduled payments of principal due
     under this Section 2.11 after June 30, 1998".

     (b) Section 2.13 of the Credit Agreement is amended by inserting the
following new subsection (f):

          "(f) Notwithstanding anything in paragraph (a), (b) or (c) above, (i)
     the Borrower shall apply 100% of the Net Proceeds of any Acceptable
     Refinancing promptly upon receipt to prepay outstanding Term Loans in
     accordance with Section 2.11(b), and (ii) the Borrower may apply the Net
     Proceeds of any Refinancing Debt incurred in compliance with Section
     6.01(g) or of any issuance and sale of its capital stock (or rights,
     warrants or options to acquire its capital stock) to repay any Indebtedness
     incurred as part of an Acceptable Refinancing or any other Refinancing
     Debt."

     SECTION 2.03 Amendments to Article VI. (a) Clause (g) of Section 6.01 is
amended to read as follows:

          "(g) Subordinated Debt issued after the Merger Date (including any
     Indebtness incurred as part of an Acceptable Refinancing, and any
     Subordinated Debt the proceeds of which are used to refinance any such
     Indebtedness or any other Subordinated Debt the proceeds of which have been
     so used ("Refinancing Debt"); provided that the terms of such Refinancing
     Debt (including, without limitation, maturity, interest rates,
     subordination provisions, prepayment, redemption, defeasance or similar
     provisions, covenants and events of default) shall be in all material
     respects at least as favorable to the Borrower and the Lenders as the terms
     of the Indebtedness being refinanced or, in the case of interest rates,
     shall be consistent with rates of interest at the time prevailing in the
     market for comparable obligations (or, if the Indebtedness being refinanced
     was incurred under the Senior Subordinated Loan Agreement or the Conversion
     Note Indenture, at least as favorable to the Borrower and the Lenders as
     the terms of the Indebtedness issued (or that would have been issued) under
     the Conversion Note Indenture including, without limitation, the interest
     rate provided for in the form of Senior Subordinated Conversion Note
     annexed as Exhibit B thereto)."

     (b) Section 6.12 is amended by deleting the text after the word
"Indebtedness" and inserting in place thereof:

Gentlemen:

     Reference is made to that certain General Shareholders Agreement (the
"Agreement") dated September 30, 1994 among Schein Pharmaceutical, Inc.
(formerly Schein Holdings, Inc.) (hereinafter "you" or the "Company"), Bayer
Corporation (formerly Miles Inc.) (hereinafter "we" or "Bayer"), each of the
family shareholders listed as such on Schedule A to the Agreement, each of the
other shareholders listed as such on Schedule A to the Agreement, and Martin
Sperber as trustee under the Voting Trust Agreement dated September 30, 1994.

     1. You have advised Bayer that the Company proposes to refinance (the
"Refinancing") a portion of its indebtedness substantially in accordance with
the attached Senior Subordinated Credit Facility Term Sheet.

     2. You have also requested that the references in the attached letter dated
June 14, 1995 between Bayer and the Company (the "Letters) to "1996" and "1997,"
be changed to "1997" and "l998", respectively.

     3. You have further requested that "stockholders equity" as determined
under the Agreement be deemed to include the amount of any charge by the Company
for acquired in process research and development expenses of the Company
resulting from the acquisition of Marsam Pharmaceuticals Inc. to the extent such
charge is less than $35,000,000.

     On the terms and subject to the fulfillment of the conditions set forth
below, and for the purposes of Section 2.3 of the Agreement, Bayer hereby
consents to the Refinancing (including the Conversion Notes thereunder) so that
upon and after such Refinancing the ratio of the sum of all Funded Debt plus the
redemption price of all Redeemable Preferred Stock of the Company and its
consolidated subsidiaries to the Company's consolidated stockholders' equity
(excluding any Redeemable Preferred Stock), determined in accordance with GAAP
(subject to the adjustment described in paragraph 3, above) (the "Ratio"),

shall forthwith be as described in the Letter as modified by paragraph 2, above.

     Notwithstanding the foregoing, if for any reason (a) any Post-Merger
Facility (as defined by the Letter) that has not been refinanced and/or (b) any
credit facility entered into in connection with the Refinancing is prepaid in
whole, again refinanced (unless such refinancing is accomplished on terms no
less favorable to Company, as determined solely by Bayer in its reasonable
discretion) or otherwise terminated, then the applicable Ratio shall thereafter
be 1.50 to 1.

     This consent shall become effective upon the execution and delivery of
definitive documentation regarding the Refinancing.

     Please indicate your acceptance of the foregoing terms and conditions
imposed by this consent by executing both of the enclosed copies of this letter
and returning one copy to the undersigned.

           $100,000,000 Senior Subordinated Loan and Conversion Notes

                                SUMMARY OF TERMS


Issuer of Notes:              Schein Pharmaceutical, Inc. (the "Company" or the
                              "Issuer").

Lender and Conversion Notes
Underwriter:                  Societe Generale or Societe Generale Securities
                              Corporation ("SocGen"), as determined by Societe
                              Generale.

Structure:                    Structured as a single facility with two parts,
                              the Initial Loan and its subsequent conversion
                              (the "Conversion") into the Conversion Notes under
                              certain circumstances as described in more detail
                              below. The Company expects that prior to the
                              issuance of the Conversion Notes, the Initial Loan
                              will be refinanced by any or all of the following:
                              bank debt, a public offering or private placement
                              of high yield senior subordinated or subordinated
                              securities or an initial public or private
                              offering of common equity of the Company or one of
                              its subsidiaries (the "Refinancing"). The Initial
                              Loan will convert to the Conversion Notes if such
                              Refinancing is not consummated and the Initial
                              Loan is outstanding as of January 31, 1998 (the
                              "Maturity Date") pursuant to the terms set forth
                              below.

                                  Initial Loan

Title of Initial Loan:        Senior Subordinated Loan.

Principal Amount:             $100,000,000 aggregate principal amount.

Closing:                      Closing of the Initial Loan (the "Closing Date")
                              is expected to occur on or before December 20,
                              1996.

Maturity:                     The Initial Loan will mature on January 31, 1998
                              unless the Conversion has occurred. If the
                              Conversion occurs, the Initial Loan will be
                              converted to the Conversion Notes described below
                              on such date, provided that (i) there shall be no
                              default under the Initial Loan or any senior
                              indebtedness of the Issuer; (ii) all fees and
                              interest payable in connection with the Initial
                              Loan shall have been paid in full; and (iii) no
                              order shall be in effect enjoining the issuance of

                              transactions contemplated hereby (to the extent
                              determined to be appropriate by SocGen) shall be
                              governed by and construed in accordance with the
                              laws of the State of New York, without giving

                                   Underwriting

Advisory Fee:                 The Company shall pay to SocGen an advisory fee
                              equal to 1.5% of the principal amount of the
                              Initial Loan upon the occurrence of a Refinancing.

Underwriting Commission:      In the event the Company selects SocGen to
                              participate as an underwriter in a Refinancing, 
                              SocGen's underwriting commission (to be
                              determined at the time of Refinancing) shall be
                              reduced by an amount equal to the lesser of (i)
                              SocGen's total underwriting commission earned from
                              such Refinancing and (ii) the Advisory Fee. In the
                              event such underwriting commission exceeds
                              $1,500,000, the Company selects SocGen to act as
                              lead manager of such an underwriting, and SocGen
                              earns at least 70% of the total commissions paid
                              for such underwriting, and SocGen shall reimburse
                              the Company for expenses incurred by the Company
                              in connection with the Refinancing in an amount
                              equal to the lesser of (i) SocGen's total
                              underwriting commission earned from such
                              Refinancing minus $1,500,000 and (ii) $500,000.

     Indebtedness incurred as part of an Acceptable Refinancing, (b) any
     Refinancing Debt or (c) any other Subordinated Debt, in each case in a
     manner adverse in any respect to the Borrower or to the Lenders, without

     SECTION 2.05. FoxMeyer Receivables. The provisions of Sections 5.11 and
6.02 of the Credit Agreement and the provisions of the Security Agreement are
waived to the extent (and only to the extent) necessary to permit the Borrower
to assign the pre-bankruptcy receivables of FoxMeyer Corporation and its
affiliates ("FoxMeyer") to National Union Fire Insurance Company ("National
Union"), as required under the terms of a credit insurance policy issued by
National Union in favor of the Borrower in order to perfect a claim of the
Borrower under such policy (estimated by the Borrower to be in the range of
$3,300,000 to $3,600,000) resulting from the bankruptcy of FoxMeyer. In
connection with such assignment, the Collateral Agent is authorized and directed
to execute, deliver and file all such instruments and other documents as it may
deem necessary to effect or evidence the release of such receivables from the
Lien of the Security Agreement.

include, without limitation, any Indebtedness of the Borrower the terms of
which (including, without limitation, principal amount, maturity, interest
rates, subordination provisions, prepayment or similar provisions, covenants and
events of default) are in all material respects at least as favorable to the
Borrower and the Lenders as the terms set forth in Exhibit A.

Administrative Agent for the Lenders hereunder (in such capacity, the
"Administrative Agent").

                              W I T N E S S E T H:

     WHEREAS, the Borrower has requested that the Lenders enter into this
Agreement to make available to the Borrower a credit facility in the amount of
$100,000,000, and the Lenders are willing to do so on the terms and conditions
contained herein;

     NOW, THEREFORE, the parties hereto agree as follows:

                                    ARTICLE I

                                   Definitions

     SECTION 1.1. Defined Terms. As used in this Agreement, the following terms
shall have the meanings specified below:

          "ABR Borrowing" shall mean a Borrowing comprised of ABR Loans.

          "ABR Loan" shall mean any Loan bearing interest at a rate determined
     by reference to the Alternate Base Rate in accordance with the provisions
     of Article II.

          "Adjusted LIBO Rate" shall mean, with respect to any Interest Period,
     an interest rate per annum (rounded upwards, if necessary, to the next 1/16
     of 1%) equal to the product of (a) the LIBO Rate in effect for such
     Interest Period and (b) Statutory Reserves.

          "Administrative Agent" has the meaning specified in the introductory
     paragraph of this Agreement.

          "Administrative Questionnaire" shall mean an Administrative
     Questionnaire in the form of Exhibit A.

     quotations in accordance with the terms thereof, the Alternate Base Rate
     shall be determined as if the Base CD Rate or the Federal Funds Effective
     Rate, or both, as appropriate, were unchanged from that existing on the
     last date for which ascertainment thereof was made, until the circumstances
     giving rise to such inability no longer exist. Any change in the Alternate
     Base Rate due to a change in the Prime Rate, the Base CD Rate or the

          "Assessment Rate" shall mean for any date the annual rate (rounded
     upwards, if necessary, to the next 1/100 of 1%) most recently estimated by
     the Administrative Agent as the then current net annual assessment rate
     that will be employed in determining amounts payable by the Administrative
     Agent to the Federal Deposit Insurance Corporation (or any successor

     SECTION 2.1. Commitments. Subject to the terms and conditions and relying
upon the representations and warranties herein set forth, each Lender agrees,
severally and not jointly, to make a term loan to the Borrower on the Closing
Date in a principal amount equal
<PAGE>
 
                                                                              20

to the Commitment of such Lender. Amounts paid or prepaid in respect of the
Loans may not be reborrowed.

     SECTION 2.2. Loans. (a) Each loan hereunder (collectively, the "Loans")
shall be made as part of a Borrowing consisting of Loans made by the Lenders
ratably in accordance with their applicable Commitments; provided, however, that
the failure of any Lender to make any Loan shall not in itself relieve any other
Lender of its obligation to lend hereunder (it being understood, however, that
no Lender shall be responsible for the failure of any other Lender to make any
Loan required to be made by such other Lender).

     (b) Subject to Sections 2.8 and 2.13, each Borrowing shall be comprised
entirely of ABR Loans or Eurodollar Loans as the Borrower may request pursuant
to Section 2.3. Each Lender may at its option make any Eurodollar Loan by
causing any domestic or foreign branch or Affiliate of such Lender to make such
Loan; provided, however, that (i) any exercise of such option shall not affect
the obligation of the Borrower to repay such Loan in accordance with the terms
of this Agreement and (ii) the exercise of such option shall not result in an
increase in Statutory Reserves above those applicable to members of the Federal
Reserve System. Borrowings of more than one Type may be outstanding at the same
time; provided, however, that the Borrower shall not be entitled to request any
Borrowing that, if made, would result in more than three Eurodollar Borrowings
outstanding hereunder at any time. For purposes of the foregoing, Borrowings
having different Interest Periods, regardless of whether they commence on the
same date, shall be considered separate Borrowings.

     (c) Each Lender shall make the Loan to be made by it hereunder on the
Closing Date by wire transfer of immediately available funds to such account in
New York City as the Administrative Agent may designate not later than 1:00
p.m., New York City time, and the Administrative Agent shall by 2:00 p.m., New
York City time, credit the amounts so received to an account of the Borrower
designated by the Borrower in the applicable borrowing request.

     (d) Unless the Administrative Agent shall have received notice from a
Lender prior to 1:00 p.m. on the Closing Date that such Lender shall not make
available to the Administrative Agent such Lender's portion of the Borrowing to
be effected on such Date, the Administrative Agent may assume that such Lender
has made such portion available to the Administrative Agent on the Closing Date
in accordance with paragraph (c) above and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on the Closing
Date a corresponding amount. If the Administrative Agent shall have so made
funds available then, to the extent that such Lender shall not have made such
portion available to the Administrative Agent, the Borrower and such Lender
severally agree to repay to the Administrative Agent, in the case of the
Borrower, within one Business Day of demand, and in the case of such Lender,
forthwith on demand, such corresponding amount together with interest thereon,
for each day from and including the date such amount is made available to the
Borrower until the date such amount is repaid to the Administrative Agent at (i)
in the case of the Borrower, the interest rate applicable at the time to the
Loans comprising such Borrowing and (ii) in the case of such Lender, a rate
determined by the Administrative Agent to represent its cost of overnight or
short-term funds (which
<PAGE>
 
                                                                              21

determination shall be conclusive absent manifest error). If such Lender shall
repay to the Administrative Agent such corresponding amount, such amount shall
constitute such Lender's Loan as part of such Borrowing for purposes of this
Agreement. The Administrative Agent will promptly notify the Borrower of any
Lender's failure to make available such Lender's portion of any Borrowing if
such failure continues unremedied for one Business Day.

     (e) Notwithstanding any other provision of this Agreement, the Borrower
shall not be entitled to request any Eurodollar Borrowing if the Interest Period
requested with respect thereto would end after the Maturity Date.

     SECTION 2.3. Borrowing Procedure. In order to request the Borrowing to be
made on the Closing Date, the Borrower shall telecopy (with receipt confirmed
telephonically) to the Administrative Agent a written borrowing request (a) in
the case of a Eurodollar Borrowing, not later than 10:30 a.m., New York City
time, two Business Days before a proposed Borrowing, and (b) in the case of an
ABR Borrowing, not later than 10:30 a.m., New York City time, on the same
Business Day as the proposed Borrowing is to be made. Such borrowing request
shall be irrevocable, shall be signed by or on behalf of the Borrower and shall
specify the following information: (i) whether the Borrowing then being
requested is to be a Eurodollar Borrowing or an ABR Borrowing; (ii) the date of
the Borrowing (which shall be a Business Day); (iii) the number and location of
the account to which funds are to be disbursed (which shall be an account that
complies with the requirements of Section 2.2(c)); and (iv) the length of the
initial Interest Period with respect thereto. If no election as to the Type of
Borrowing is specified in any such notice, then the requested Borrowing shall be
an ABR Borrowing. If no interest Period with respect to any Eurodollar Borrowing
is specified in any such notice, then the Borrower shall be deemed to have
selected an Interest Period of one month's duration. The Administrative Agent
shall promptly (and in any event on the same day that the Administrative Agent
receives such notice, if received by 1:00 p.m., New York City time, on such day)
advise the applicable Lenders of any notice given pursuant to this Section 2.3
(and the contents thereof), and of each Lender's portion of the requested
Borrowing.

     SECTION 2.4. Evidence of Debt; Repayment of Loans. (a) The Borrower hereby
unconditionally promises to pay to the Administrative Agent for the account of
each Lender the principal amount of the Loan made by such Lender on the Maturity
Date (subject, however, to the provisions of Section 2.20).

     (b) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness of the Borrower to such Lender
resulting from the Loan made by such Lender, including the amounts of principal
and interest payable and paid such Lender from time to time under this
Agreement.

     (c) The Administrative Agent shall maintain accounts in which it shall
record (i) the amount of each Loan made hereunder, the Type thereof and the
Interest Period applicable thereto, (ii) the amount of any principal or interest
due and payable from the Borrower to each Lender hereunder and (iii) the amount
of any sum received by the Administrative Agent hereunder from the Borrower and
each Lender's share thereof.

                                                                              22

     (d) The entries made in the accounts maintained pursuant to paragraphs (b)
and (c) above shall be prima facie evidence of the existence and amounts of the
obligations therein recorded; provided, however, that the failure of any Lender
or the Administrative Agent to maintain such accounts or any error therein shall
not in any manner affect the obligations of the Borrower to repay the Loans in
accordance with their terms, except to the extent that the correction of such
error results in a reduction of the Borrower's obligations hereunder.

     (e) Notwithstanding any other provision of this Agreement, in the event any
Lender shall request and receive a promissory note payable to such Lender and
its registered assigns to evidence the Loan made by it hereunder, the interests
represented by such note shall at all times (including after any assignment of
all or part of such interests pursuant to Section 10.4) be represented by one or
more promissory notes payable to the payee named therein or its registered
assigns. Any such promissory notes shall include a paragraph indicating that the
obligations evidenced thereby are subject to the provisions of Article VIII
hereof.

     SECTION 2.5. Fees. (a) The Borrower shall pay to SocGen the Fees (the
"Fees") agreed to in the Fee Letter on the dates specified therein.

     (b) All Fees shall be paid on the dates due, in immediately available
funds, to the Administrative Agent for distribution, if and as appropriate as
determined by the Administrative Agent, among the Lenders but no Lender shall
have any claim against the Borrower once the Borrower has paid the Fees to the
Administrative Agent. Once paid, none of the Fees shall be refundable under any
circumstances, except to the extent such payment shall have been made as a
consequence of manifest error.

     SECTION 2.6. Interest on Loans. (a) Subject to the provisions of Section
2.7, the Loans comprising each Eurodollar Borrowing shall bear interest
(computed on the basis of the actual number of days elapsed over a year of 360
days) at a rate per annum equal to the Adjusted LIBO Rate for the Interest
Period in effect for such Borrowing plus 4.00%.

     (b) Subject to the provisions of Section 2.7, the Loans comprising each ABR
Borrowing shall bear interest (computed on the basis of the actual number of
days elapsed over a year of 365 or 366 days, as the case may be, when the
Altemate Base Rate is determined by reference to the Prime Rate and over a year
of 360 days at all other times) at a rate per annum equal to the Alternate Base
Rate plus 3.00%.

     (c) Interest shall accrue from and including the first day of an Interest
Period to but excluding the last day of such Interest Period. Interest on each
Loan shall accrue daily for the account of the holder from time to time of such
Loan and shall be payable on the Interest Payment Dates applicable to such Loan
except as otherwise provided in this Agreement. The applicable Alternate Base
Rate or Adjusted LIBO Rate for each Interest Period or day within an Interest
Period, as the case may be, shall be determined by the Administrative Agent, and
such determination shall be conclusive absent manifest error.

                                                                              23

     SECTION 2.7. Default Interest. If the Borrower shall default in the payment
of the principal of or interest on any Loan or any other amount becoming due
hereunder, by acceleration or otherwise, or under any other Loan Document, the
Borrower shall on demand from time to time pay interest, to the extent permitted
by law, on such defaulted amount to but excluding the date of actual payment
(after as well as before judgment) (a) in the case of overdue principal, at the
rate otherwise applicable to such Loan pursuant to Section 2.6 plus 2.00% per
annum and (b) in all other cases, at a rate per annum (computed on the basis of
the actual number of days elapsed over a year of 365 or 366 days, as the case
may be, when determined by reference to the Prime Rate and over a year of 360
days at all other times) equal to the sum of the Alternate Base Rate plus 5.00%.

     SECTION 2.8. Alternate Rate of Interest. In the event, and on each
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for a Eurodollar Borrowing the Administrative Agent shall have
determined in good faith that dollar deposits in the principal amounts of the
Loans comprising such Borrowing are not generally available in the London
interbank market, or that the rates at which such dollar deposits are being
offered will not adequately and fairly reflect the cost to any Lender of making
or maintaining its Eurodollar Loan during such Interest Period, or that
reasonable means do not exist for ascertaining the Adjusted LIBO Rate, the
Administrative Agent will, as soon as practicable thereafter, give written
notice of such determination to the Borrower and the Lenders. In the event of
any such determination, until the Administrative Agent shall have advised the
Borrower and the Lenders that the circumstances giving rise to such notice no
longer exist, any request by the Borrower for a Eurodollar Borrowing pursuant to
Section 2.3 or 2.9 shall be deemed to be a request for an ABR Borrowing. The
Administrative Agent will promptly advise the Borrower once the circumstances
giving rise to any such notice no longer exist. Each determination by the
Administrative Agent hereunder shall be conclusive absent manifest error.

     SECTION 2.9. Conversion and Continuation of Borrowings. The Borrower shall
have the right at any time upon prior irrevocable telephonic notice to the
Administrative Agent (confirmed promptly in writing) (a) not later than 10:30
a.m., New York City time, two Business Days prior to the proposed conversion, to
convert any Eurodollar Borrowing into an ABR Borrowing, (b) not later than 10:30
a.m., New York City time, two Business Days prior to conversion or continuation,
to convert any ABR Borrowing into a Eurodollar Borrowing or to continue any
Eurodollar Borrowing as a Eurodollar Borrowing for an additional Interest Period
and (c) not later than 10:30 a.m., New York City time, two Business Days prior
to conversion, to convert the Interest Period with respect to any Eurodollar
Borrowing to another permissible Interest Period, subject in each case to the
following:

          (i) each conversion or continuation shall be made pro rata among the
     Lenders in accordance with the respective principal amounts of the Loans
     comprising the converted or continued Borrowing;

          (ii) each requested conversion or continuation shall be with respect
     to all of the then outstanding Loans or with respect to a portion thereof
     equal to $10,000,000 or a whole multiple of $5,000,000 in excess thereof;
<PAGE>
 
                                                                              24

          (iii) each conversion shall be effected by each Lender and the
     Administrative Agent by recording for the account of such Lender the new
     Loan of such Lender resulting from such conversion and reducing the Loan
     (or portion thereof) of such Lender being converted by an equivalent
     principal amount;

          (iv) if any Eurodollar Borrowing is converted at a time other than the
     end of the Interest Period applicable thereto, the Borrower shall pay, upon
     demand, any amounts due to the Lenders pursuant to Section 2.14;

          (v) unless each Lender otherwise agrees, any portion of a Borrowing
     maturing or required to be repaid in less than one month from the date of
     any conversion or continuation may not be converted into or continued as a
     Eurodollar Borrowing;

          (vi) any portion of a Eurodollar Borrowing that cannot be converted
     into or continued as a Eurodollar Borrowing by reason of the immediately
     preceding clause shall be automatically converted at the end of the
     Interest Period in effect for such Borrowing into an ABR Borrowing;

          (vii) no Interest Period may be selected for any Eurodollar Borrowing
     that would end later than the Maturity Date;

          (viii) no Borrowing may be converted into, or continued as, a
     Eurodollar Borrowing when any Default has occurred and is continuing and
     the Administrative Agent or the Required Lenders have determined that such
     conversion or continuation is not appropriate (and, instead, any such
     Borrowing will be converted into or remain as an ABR Borrowing on the last
     day of the Interest Period applicable thereto); and

          (ix) no Borrowing may be converted into, or continued as, a Eurodollar
     Borrowing when any Event of Default has occurred and is continuing, unless
     the Required Lenders have determined that such conversion or continuation
     is appropriate (and, instead, any such Borrowing will be converted into or
     remain as an ABR Borrowing on the last day of the Interest Period
     applicable thereto).

     Each notice pursuant to this Section 2.9 shall refer to this Agreement and
specify (i) whether the Borrowing is to be converted to or continued as a
Eurodollar Borrowing or an ABR Borrowing, (ii) if such notice requests a
conversion, the date of such conversion (which shall be a Business Day) and
(iii) if such Borrowing is to be converted to or continued as a Eurodollar
Borrowing, the Interest Period with respect thereto. If no Interest Period is
specified in any such notice with respect to any conversion to or continuation
as a Eurodollar Borrowing, the Borrower shall be deemed to have selected an
Interest Period of one months duration. The Administrative Agent shall advise
the Lenders of any notice given pursuant to this Section 2.9 and of each
Lender's portion of any converted or continued Borrowing. If the Borrower shall
not have given notice in accordance with this Section 2.9 to continue any
Borrowing into a subsequent Interest Period (and shall not otherwise have given
notice in accordance with this Section 2.9 to convert such Borrowing),
<PAGE>
 
                                                                              25

such Borrowing shall, at the end of the Interest Period applicable thereto
(unless repaid pursuant to the terms hereof), automatically be continued into a
new Interest Period as a Eurodollar Borrowing having an Interest Period of one
months duration.

     SECTION 2.10. Optional Prepayment. (a) The Borrower shall have the right at
any time and from time to time to prepay any Borrowing, in whole or in part,
upon at least two Business Days' prior irrevocable telephonic notice (promptly
confirmed in writing) to the Administrative Agent before 10:30 a.m., New York
City time; provided, however, that each partial prepayment shall be in an amount
that is an integral multiple of $1,000,000 and provided, further, that no
prepayment shall be permitted under this Section 2.10 if, after giving effect
thereto, the aggregate principal amount of the then outstanding Loans would be
less than $75,000,000 but greater than $0.

     (b) Each notice of prepayment shall specify the prepayment date and the
principal amount of each Borrowing (or portion thereof) to be prepaid and shall
commit the Borrower to prepay such Borrowing by the amount stated therein on the
date stated therein. All prepayments under this Section 2.10 shall be subject to
Section 2.14 but otherwise without premium or penalty. All prepayments under
this Section 2.10 shall be accompanied by accrued interest on the principal
amount being prepaid to but excluding the date of payment.

     SECTION 2.11. Mandatory Prepayments. (a) The Borrower shall, if and to the
extent required pursuant to the Chase Credit Facility, apply 100% of the Net
Proceeds of any Asset Sale promptly upon its receipt thereof (or, if applicable,
promptly upon any amounts being deemed to constitute Net Proceeds as provided in
the definition of such term) to (i) prepay the term loans outstanding under the
Chase Credit Facility and/or (ii) prepay revolving credit loans outstanding
under the Chase Credit Facility provided that the commitment of the lenders
thereunder to lend revolving credit loans shall be permanently reduced to the
extent of such prepayment. To the extent not used in accordance with the
preceding sentence, the Borrower shall, or shall cause its Subsidiaries to,
prepay Borrowings with such Net Proceeds not later than the date which is one
Business Day after the date of receipt thereof.

     (b) The Borrower shall apply 100% of the Net Proceeds of any Equity
Issuance promptly upon its receipt thereof (or, if applicable, promptly upon any
amounts being deemed to constitute Net Proceeds as provided in the definition of
such term) to prepay Borrowings with such Net Proceeds not later than the date
which is one Business Day after the date of receipt thereof.

     (c) Anything in Section 2.1 1(a) or (b) to the contrary notwithstanding,
the Borrower shall not be required to make any prepayment pursuant to such
Sections to the extent that, after giving effect thereto, the aggregate
principal amount of the then outstanding Loans would be less than $75,000,000
but greater than $0, provided, however, that if at any time the aggregate amount
of prepayments pursuant to such Sections that shall have been prevented from
being made pursuant to the operation of the foregoing provisions of this
paragraph shall equal or exceed $75,000,000 then such prepayments shall be
required to be
<PAGE>
 
                                                                              26

made at such time and, provided, further, that, until applied in accordance with
the foregoing proviso, all Net Proceeds otherwise required to prepay the Loans
and not applied to effect a prepayment pursuant to the operation of this
paragraph shall be held in a cash collateral account established by the
Administrative Agent the amounts on deposit in which shall be invested in
Permitted Investments designated by the Borrower (or, in the absence of such
designation, as selected by the Administrative Agent in its sole discretion)
subject to the right of the Required Lenders at any time to require that the
amounts on deposit in such cash collateral account be applied to make the
prepayments otherwise prevented by this paragraph.

     (d) The Borrower shall deliver to the Administrative Agent (i) at the time
of each prepayment required under this Section 2.11, a certificate signed by a
Financial Of fleer of the Borrower setting forth in reasonable detail the
calculation of the amount of such prepayment and (ii) not later than the later
of (A) the date on which a Responsible Officer of the Borrower becomes aware
that such prepayment will be made and (B) the date that is three Business Days
prior to the date of such prepayment, a notice of such prepayment. Such
certificate shall also describe in reasonable detail the facts and circumstances
giving rise to the applicable prepayment event and a reasonably detailed
calculation of the Net Proceeds therefrom.

     (e) All prepayments under this Section 2.11 shall be subject to Section
2.14 but otherwise without premium or penalty. All prepayments under this
Section 2.11 shall be accompanied by accrued interest on the principal amount
being prepaid to but excluding the date of payment.

     SECTION 2.12. Reserve Requirements; Change in Circumstances. (a)
Notwithstanding any other provision of this Agreement, if after the date of this
Agreement any change in applicable law or regulation or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof (whether or not having the force of
law) shall change the basis of taxation of payments to any Lender of the
principal of or interest on any Eurodollar Loan held by such Lender or any Fees
or other amounts payable hereunder (other than changes in respect of taxes
imposed on the overall net income of such Lender by the jurisdiction in which
such Lender has its principal office or by any political subdivision or taxing
authority therein), or shall impose, modify or deem applicable any reserve,
special deposit or similar requirement against assets of, deposits with or for
the account of or credit extended by any Lender (except any such reserve
requirement that is fully reflected in the Adjusted LIBO Rate) or shall impose
on such Lender or the London interbank market any other condition affecting this
Agreement or any Eurodollar Loan held by such Lender, and the result of any of
the foregoing shall be to increase the cost to such Lender of making or
maintaining any Eurodollar Loan by an amount deemed by such Lender to be
material, then the Borrower shall pay to such Lender upon demand such additional
amount or amounts as shall compensate such Lender for such additional costs
incurred or reduction suffered.

     (b) If any Lender shall determine that the adoption after the date of this
Agreement of any law, rule, regulation, agreement or guideline regarding capital
adequacy, or any change after the date hereof in any such law, rule, regulation,
agreement or guideline
<PAGE>
 
                                                                              27

(whether such law, rule, regulation, agreement or guideline has been adopted) or
in the interpretation or administration thereof by any Governmental Authority
charged with the interpretation or administration thereof, or compliance by any
Lender or any Lender's holding company with any request or directive regarding
capital adequacy (whether or not having the force of law) of any Governmental
Authority has or would have the effect of reducing the rate of return on such
Lender's capital or on the capital of such Lender's holding company, if any, as
a consequence of this Agreement or the Loans made by such Lender pursuant hereto
to a level below that which such Lender or such Lender's holding company could
have achieved but for such applicability, adoption, change or compliance (taking
into consideration such Lender's policies and the policies of such Lender's
holding company with respect to capital adequacy) by an amount deemed by such
Lender to be material, then from time to time the Borrower shall pay to such
Lender, as the case may be, such additional amount or amounts as shall
compensate such Lender or such Lender's holding company for any such reduction
suffered.

     (c) A certificate of a Lender setting forth in reasonable detail (i) the
calculation of the amount or amounts necessary to compensate such Lender or its
holding company, as applicable, as specified in paragraph (a) or (b) above and
(ii) the facts and circumstances giving rise to such compensation, shall be
delivered to the Borrower and shall be conclusive absent manifest error. The
Borrower shall pay such Lender the amount shown as due on any such certificate
delivered by it within 10 Business Days after its receipt of the same.

     (d) Failure or delay on the part of any Lender to demand compensation for
any increased costs or reduction in amounts received or receivable or reduction
in return on capital shall not constitute a waiver of such Lender's right to
demand such compensation; provided, however, that the Lender may not demand
compensation under this Section 2.12 for any period commencing earlier than 60
days prior to such demand. The protection of this Section 2.12 shall be
available to each Lender regardless of any possible contention of the invalidity
or inapplicability of the law, rule, regulation, agreement, guideline or other
change or condition that shall have occurred or been imposed; provided, however,
that each Lender shall take reasonable actions (which shall not require such
Lender to incur an unreimbursed loss or unreimbursed cost or expense or
otherwise take any action precluded by legal or regulatory restrictions or
suffer any disadvantage or burden deemed by it to be significant) to avoid any
need to claim compensation under this Section 2.12 arising out of any reasonably
foreseeable change in circumstances.

     (e) Without prejudice to the survival of any other agreement contained
herein, the agreements and obligations contained in this Section 2.12 shall
survive the payment in full of the principal of and interest on all Loans made
hereunder. 

     SECTION 2.13. Change in Legality. (a) Notwithstanding any other provision
of this Agreement, if after the date of this Agreement, any change in any law or
regulation or in the interpretation thereof by any Governmental Authority
charged with the administration or interpretation thereof shall make it unlawful
for any Lender to make or hold any
<PAGE>
 
                                                                              28

Eurodollar Loan or to give effect to its obligations as contemplated hereby with
respect to any Eurodollar Loan, then, by written notice to the Borrower and to
the Administrative Agent:

          (i) such Lender may declare that Eurodollar Loans shall not thereafter
     (for the duration of such unlawfulness) be made by such Lender hereunder
     (or be continued for additional Interest Periods and ABR Loans will not
     thereafter (for such duration) be converted into Eurodollar Loans),
     whereupon any request for a Eurodollar Loan (or to convert an ABR Loan to a
     Eurodollar Loan or to continue a Eurodollar Loan, for an additional
     Interest Period) shall, as to such Lender only, be deemed a request for an
     ABR Loan (or a request to continue an ABR Loan as such for an additional
     Interest Period or to convert a Eurodollar Loan into an ABR Loan, as the
     case may be), unless such declaration shall be subsequently withdrawn; and

          (ii) such Lender may require that all outstanding Eurodollar Loans
     made by it be converted to ABR Loans, in which event all such Eurodollar
     Loans shall be automatically converted to ABR Loans as of the effective
     date of such notice as provided in paragraph (b) below (and Section 2.14
     shall not apply to any such automatic conversion).

In the event any Lender shall exercise its rights under clause (i) or (ii)
above, all payments and prepayments of principal that would otherwise have been
applied to repay the Eurodollar Loans that would have been made by such Lender
or the converted Eurodollar Loans of such Lender shall instead be applied to
repay the ABR Loans made by such Lender in lieu of, or resulting from the
conversion of, such Eurodollar Loans.

     (b) For purposes of this Section 2.13, a notice to the Borrower by any
Lender shall be effective as to each Eurodollar Loan made by such Lender, if
lawful, on the last day of the Interest Period currently applicable to such
Eurodollar Loan; in all other cases such notice shall be effective on the date
of receipt by the Borrower.

     SECTION 2.14. Indemnity. The Borrower shall indemnify each Lender against
any loss or expense that such Lender may sustain or incur as a direct
consequence of (a) any event, other than a default by such Lender in the
performance of its obligations hereunder, which results in (i) such Lender
receiving or being deemed to receive any amount on account of the principal of
any Eurodollar Loan prior to the end of the Interest Period in effect therefor,
(ii) the conversion of any Eurodollar Loan to an ABR Loan, or the conversion of
the Interest Period with respect to any Eurodollar Loan, in each case other than
on the last day of the Interest Period in effect therefor, or (iii) any
Eurodollar Loan to be made by such Lender not being made after notice of such
Loan shall have been given by the Borrower hereunder (any of the events referred
to in this clause (a) being called a "Breakage Event") or (b) any default in the
making of any payment or prepayment required to be made hereunder. In the case
of any Breakage Event, such loss shall include an amount equal to the excess, as
reasonably determined by such Lender, of (i) its cost of obtaining funds for the
Eurodollar Loan that is the subject of such Breakage Event for the period from
the date of such Breakage Event to the last day of the Interest Period in effect
(or that would have been in effect) for such Loan over (ii) the amount of
interest likely to be realized by such Lender in
<PAGE>
 
                                                                              29

redeploying the funds released or not utilized by reason of such Breakage Event
for such period. A certificate of any Lender setting forth in reasonable detail
(i) the calculation of any amount or amounts which such Lender is entitled to
receive pursuant to this Section 2.14 and (ii) the facts and circumstances
giving rise to such entitlement, shall be delivered to the Borrower (in the case
of a claim under clause (a) above, within 60 days of the applicable Breakage
Event) and shall be conclusive absent manifest error. Without prejudice to the
survival of any other agreement contained herein, the agreements and obligations
contained in this Section 2.14 shall survive the payment in full of the
principal of and interest on all Loans made hereunder.

     SECTION 2.15. Pro Rata Treatment. Except as required under Section 2.13,
each Borrowing, each payment or prepayment of principal of any Borrowing, each
payment of interest on the Loans, and each refinancing of any Borrowing with,
conversion of any Borrowing to or continuation of any Borrowing as a Borrowing
of any Type shall be allocated pro rata among the Lenders in accordance with the
respective principal amounts of their outstanding Loans. In computing any
Lender's portion of any Borrowing to be made hereunder, the Administrative Agent
may, in its discretion, round each Lender's percentage of such Borrowing to the
next higher or lower whole dollar amount.

     SECTION 2.16. Sharing of Setoffs. If any Lender shall, through the exercise
of a right of banker's lien, setoff or counterclaim against the Borrower, or
pursuant to a secured claim under Section 506 of Title 11 of the United States
Code or other security or interest arising from, or in lieu of, such secured
claim, received by such Lender under any applicable bankruptcy, insolvency or
other similar law or otherwise, or by any other means, obtain payment (voluntary
or involuntary) in respect of any Loan as a result of which the unpaid principal
portion of its Loans shall be proportionately less than the unpaid principal
portion of the Loans of any other Lender, it shall be deemed simultaneously to
have purchased from such other Lender at face value, and shall promptly pay to
such other Lender the purchase price for, a participation in the Loans of such
other Lender, so that the aggregate unpaid principal amount of the Loans held by
each Lender shall be in the same proportion to the aggregate unpaid principal
amount of all Loans then outstanding as the principal amount of its Loans prior
to such exercise of banker's lien, setoff or counterclaim or other event was to
the principal amount of all Loans outstanding prior to such exercise of banker's
lien, setoff or counterclaim or other event; provided, however' that if any such
purchase or purchases or adjustments shall be made pursuant to this Section 2.16
and the payment giving rise thereto shall thereafter be recovered, such purchase
or purchases or adjustments shall be rescinded to the extent of such recovery
and the purchase price or prices or adjustment restored without interest. The
Borrower expressly consents to the foregoing arrangements and agrees that any
Lender holding a participation in a Loan deemed to have been so purchased may
exercise any and all rights of banker's lien, setoff or counterclaim with
respect to any and all moneys owing by the Borrower to such Lender by reason
thereof as fully as if such Lender had made a Loan directly to the Borrower in
the amount of such participation.

     SECTION 2.17. Payments. (a) The Borrower shall make each payment (including
principal of or interest on any Borrowing or any Fees or other amounts)
hereunder and under any other Loan Document not later than 1:00 p.m., New York
City time, on the
<PAGE>
 
                                                                              30

date when due in immediately available dollars, without setoff, defense or
counterclaim (but without prejudice, waiver or effect of estoppel with respect
to any defense or counterclaim). Each such payment shall be made to the
Administrative Agent at its offices at 1221 Avenue of the Americas, New York,
New York 10020.

     (b) Whenever any payment (including principal of or interest on any
Borrowing, any Fees or any other amounts) hereunder or under any other Loan
Document shall become due, or otherwise would occur, on a day that is not a
Business Day, such payment may be made on the next succeeding Business Day, and
such extension of time shall in such case be included in the computation of
interest or Fees, if applicable.

     SECTION 2.18. Taxes. (a) Any and all payments by the Borrower hereunder and
under any other Loan Document shall be made, in accordance with Section 2.17,
free and clear of and without deduction for any and all current or future taxes,
levies, imposts, deductions, charges or withholdings, and all liabilities with
respect thereto, excluding (i) income taxes imposed on the net income of the
Administrative Agent or any Lender (or any transferee or assignee thereof,
including a participation holder (any such entity a "Transferee")) and (ii)
franchise taxes imposed on the net income of the Administrative Agent or any
Lender (or Transferee), in each case by the jurisdiction (A) under the laws of
which the Administrative Agent or any Lender (or Transferee) is organized or any
political subdivision thereof or (B) in which the applicable office of the
Administrative Agent or any Lender (or any Transferee) is located or any
political subdivision thereof (all such nonexcluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities, collectively or individually,
being called "Taxes"). If the Borrower shall be required to deduct any Taxes
from or in respect of any sum payable hereunder or under any other Loan Document
to the Administrative Agent or any Lender (or any Transferee), (i) the sum
payable shall be increased by the amount (an "additional amount") necessary so
that after making all required deductions (including deductions applicable to
additional sums payable under this Section 2.18) the Administrative Agent or any
Lender (or Transferee), as the case may be, shall receive an amount equal to the
sum it would have received had no such deductions been made, (ii) the Borrower
shall make such deductions and (iii) the Borrower shall pay the full amount
deducted to the relevant Governmental Authority in accordance with applicable
law.

     (b) In addition, the Borrower agrees to bear and shall pay to the relevant
Governmental Authority in accordance with applicable law any current or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies (including mortgage recording taxes and similar fees) that arise
from any payment made hereunder or under any other Loan Document or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement or any other Loan Document ("Other Taxes").

     (c) The Borrower shall indemnify the Administrative Agent or any Lender (or
Transferee) for the full amount of Taxes and Other Taxes paid by the
Administrative Agent or any Lender (or Transferee), as the case may be, and any
liability (including penalties, interest and expenses (including reasonable
attorney's fees and expenses)) arising therefrom or with respect thereto,
whether or not such Taxes or Other Taxes were correctly or legally asserted by
the relevant Governmental Authority. A certificate as to the amount of such
<PAGE>
 
                                                                              31

payment or liability prepared by the Administrative Agent or any Lender (or
Transferee), or the Administrative Agent on its behalf, and setting forth in
reasonable detail (i) the calculation of and (ii) the facts and circumstances
giving rise to such payment or liability, absent manifest error, shall be final,
conclusive and binding for all purposes. Such indemnification shall be made
within 30 days after the date the Administrative Agent or any Lender (or
Transferee), as the case may be, makes written demand therefor. No Lender (or
Transferee) may make any claim for indemnification more than 180 days after such
Lender (or Transferee) knows of the payment or liability with respect to which
such indemnification is to be sought (such 180 days to be reduced to 60 days if
at the time of such claim for indemnification such Lender (or Transferee) holds
Loans or participations therein.

     (d) If the Administrative Agent or any Lender (or Transferee) receives a
refund in respect of any Taxes or Other Taxes as to which it has been
indemnified by the Borrower or with respect to which the Borrower has paid
additional amounts pursuant to this Section 2.18, it shall within 30 days from
the date of such receipt pay over such refund to the Borrower (but only to the
extent of indemnity payments made, or additional amounts paid, by the Borrower
under this Section 2.18 with respect to the Taxes or Other Taxes giving rise to
such refund), net of all out-of-pocket expenses of the Administrative Agent or
such Lender (or Transferee) and without interest (other than interest paid by
the relevant Governmental Authority with respect to such refund); provided,
however, that the Borrower, upon the request of the Administrative Agent or such
Lender (or Transferee), shall repay the amount paid over to the Borrower (plus
penalties, interest or other charges) to the Administrative Agent or such Lender
(or Transferee) in the event the Administrative Agent or such Lender (or
Transferee) is required to repay such refund to such Governmental Authority.

     (e) As soon as practicable after the date of any payment of Taxes or Other
Taxes by the Borrower to the relevant Governmental Authority, the Borrower shall
deliver to the Administrative Agent, at its address referred to in Section 10.1,
the original or a certified copy of a receipt issued by such Governmental
Authority evidencing payment thereof.

     (f) Without prejudice to the survival of any other agreement contained
herein, the agreements and obligations contained in this Section 2.18 shall
survive the payment in full of the principal of and interest on all Loans made
hereunder.

     (g) Each Lender (or Transferee) that is organized under the laws of a
jurisdiction other than the United States, any State thereof or the District of
Columbia (a "Non-U.S. Lender") shall deliver to the Borrower and the
Administrative Agent two copies of either United States Internal Revenue Service
Form 1001 or Form 4224, or, in the case of a Non-U.S. Lender claiming exemption
from U.S. Federal withholding tax under Section 871(h) or 881(c) of the Code
with respect to payments of "portfolio interest", a Form W-8, or any subsequent
versions thereof or successors thereto (and, if such Non-U.S. Lender delivers a
Form W-8, a certificate representing that such Non-U.S. Lender is not a bank for
purposes of Section 881(c) of the Code, is not a 10-percent shareholder (within

reduced rate of, U.S. Federal withholding tax on payments by the Borrower under
this Agreement and the other Loan Documents. Such forms shall be delivered by
each Non-U.S. Lender on or before the date it becomes a party to this Agreement
(or, in the case of a Transferee that is a participation holder, on or before
the date such participation holder becomes a Transferee hereunder) and on or
before the date, if any, such Non-U.S. Lender changes its applicable office by
designating a different office (a "New Office"). In addition, each Non-U.S.
Lender shall deliver such forms promptly upon the obsolescence or invalidity of
any form previously delivered by such Non-U.S. Lender. Notwithstanding any other
provision of this paragraph (g), a Non-U.S. Lender shall not be required to
deliver any form pursuant to this paragraph (g) that such Non-U.S. Lender is not
legally able to deliver.

     (h) The Borrower shall not be required to indemnify any Non-U.S. Lender or
to pay any additional amounts to any Non-U.S. Lender, in respect of United
States Federal withholding tax pursuant to paragraph (a) or (c) above to the
extent that (i) the obligation to withhold amounts with respect to United States
Federal withholding tax existed on the date such Non-U.S. Lender became a party
to this Agreement (or, in the case of a Transferee that is a participation
holder, on the date such participation holder became a Transferee hereunder) or,
with respect to payments to a New Office, the date such Non-U.S. Lender
designated such New Office with respect to a Loan; provided, however, that this
paragraph (h) shall not apply (x) to any Transferee or New Office that becomes a
Transferee or New Office as a result of an assignment, participation, transfer
or designation made at the request of the Borrower and (y) to the extent the
indemnity payment or additional amounts any Transferee, or any Lender (or
Transferee), acting through a New Office, would be entitled to receive (without
regard to this paragraph (h)) do not exceed the indemnity payment or additional
amounts that the Person making the assignment, participation or transfer to such
Transferee, or Lender (or Transferee) making the designation of such New Office,
would have been entitled to receive in the absence of such assignment,
participation, transfer or designation or (ii) the obligation to pay such
additional amounts would not have arisen but for a failure by such Non-U.S.
Lender to comply with the provisions of paragraph (g) above.

     (i) Nothing contained in this Section 2.18 shall require any Lender (or any
Transferee) or the Administrative Agent to make available any of its tax returns
(or any other information that it deems to be confidential or proprietary).

     SECTION 2.19. Assignment of Commitments under Certain Circumstances; Duty
To Mitigate. (a) In the event (i) any Lender delivers a certificate requesting
compensation pursuant to Section 2.12, (ii) any Lender delivers a notice
described in Section 2.13, (iii) the Borrower is required to pay any additional
amount to any Lender or any Governmental Authority on account of any Lender
pursuant to Section 2.18 or (iv) the Administrative Agent notifies the Borrower
of any Lender's failure to fund as provided in Section 2.2(d), the Borrower may,
at its sole expense and effort, upon notice to such Lender and the
Administrative Agent, require such Lender to transfer and assign, without
recourse (in accordance with and subject to the restrictions contained in
Section 10.4), all its interests, rights and obligations under this Agreement to
an assignee that shall assume such assigned obligations (which assignee may be
another Lender, if a Lender accepts such assignment); provided, however, that
(x) such assignment shall not conflict with any law, rule or regulation
<PAGE>
 
                                                                              33

or order of any court or other Governmental Authority having jurisdiction, (y)
the Borrower or such assignee shall have paid to the affected Lender in
immediately available funds an amount equal to the sum of the principal of the
outstanding Loans of such Lender plus all other amounts (excluding interest and
Fees, which shall be paid when due to the assigning Lender under Sections 2.6
and 2.5, respectively) accrued for the account of such Lender hereunder
(including any amounts under Sections 2.12, 2.14 and 2.18) and (z) if prior to
any such transfer and assignment the circumstances or event that resulted in
such Lender's claim for compensation under Section 2.12 or notice under Section
2.13 or the amounts paid pursuant to Section 2.18, as the case may be, cease to
cause such Lender to suffer increased costs or reductions in amounts received or
receivable or reduction in return on capital, or cease to have the consequences
specified in Section 2.13, or cease to result in amounts being payable under
Section 2.18, as the case may be (including as a result of any action taken by
such Lender pursuant to paragraph (b) below), or if such Lender shall waive its
right to claim fiber compensation under Section 2.12 in respect of such
circumstances or event or shall withdraw its notice under Section 2.13 or shall
waive its right to further payments under Section 2.18 in respect of such
circumstances or event or shall fund as provided in Section 2.2(d), as the case
may be, then such Lender shall not thereafter be required to make any such
transfer and assignment hereunder.

     (b) If (i) any Lender shall request compensation under Section 2.12, (ii)
any Lender delivers a notice described in Section 2.13 or (iii) the Borrower is
required to pay any additional amount to any Lender or any Governmental
Authority on account of any Lender, pursuant to Section 2.18, then such Lender
shall use reasonable efforts (which shall not require such Lender to incur an
unreimbursable loss or unreimbursable cost or expense or otherwise take any
action inconsistent with its internal policies or legal or regulatory
restrictions or suffer any disadvantage or burden deemed by it in good faith to
be significant) (x) to file any certificate or document reasonably requested in
writing by the Borrower or (y) to assign its rights and delegate and transfer
its obligations hereunder to another of its offices, branches or affiliates, if
such filing or assignment would reduce its claims for compensation under Section
2.12 or enable it to withdraw its notice pursuant to Section 2.13 or would
reduce amounts payable pursuant to Section 2.18, as the case may be, in the
future. The Borrower shall pay all reasonable costs and expenses incurred by any
Lender in connection with any such filing or assignment, delegation and
transfer.

     SECTION 2.20. Conversion Notes. On the Conversion Date: the Borrower shall
deliver to each Lender a Conversion Note payable to the order of such Lender in
a principal amount equal to 103.5% of the principal amount of the Loan then held
by such Lender; such Lender shall accept such Conversion Note in exchange for
any promissory note then held by such Lender as evidence of such Loan; and such
Loan shall thereafter be evidenced and governed by and be payable in accordance
with such Conversion Note and the Conversion Note Indenture; provided, however,
that the exchange of promissory notes provided for in this Section 2.20 shall
not occur unless on the Conversion Date the following conditions shall have been
satisfied:

          (i) all accrued interest on all Loans shall have been paid in full in
     cash;
<PAGE>
 
                                                                              34

          (ii) no Default or Event of Default shall have occurred and be
     continuing, and no Default or Event of Default (as such terms are defined
     in the Chase Credit Agreement) shall have occurred and be continuing;

          (iii) such exchange would not violate any law or regulation or any
     order or decree of any court or Governmental Body applicable to the
     Borrower;

          (iv) The Borrower and a trustee satisfactory to the Borrower and the
     Administrative Agent shall have executed and delivered the Conversion Note
     Indenture substantially in the form of Exhibit C hereto; and

          (v) the Lenders shall have received (A) an opinion of counsel for the
     Borrower as to the Conversion Notes and the Conversion Note Indenture, in
     form and substance reasonably satisfactory to the Administrative Agent, and
     (B) a certificate of the Borrower, signed by a Responsible Officer, as to
     the names, officers and signatures of its officers executing the Conversion
     Notes and the Conversion Note Indenture on such date.

     The Conversion Notes (if any) issued pursuant to this Section 2.20 will
mature on the Maturity Date.

                                   ARTICLE III

                 Representations and Warranties of the Borrower

     The Borrower represents and warrants to the Administrative Agent and the

authority to own its property and assets and to carry on its business as now
conducted and as proposed to be conducted, (c) is qualified to do business in,
and is in good standing in, every jurisdiction where such qualification is
required, except where the failure so to qualify could not reasonably be
expected to result in a Material Adverse Effect, and (d) has the corporate power
and authority to execute, deliver and perform its obligations under each of the
Loan Documents and each other agreement or instrument contemplated hereby to
which it is or will be a party.

     SECTION 3.2. Authorization. The execution, delivery and performance by the
Borrower and each Subsidiary of this Agreement and each other Loan Document
(collectively, the "Transactions") (a) have been duly authorized by all

violate (A) any provision of law, statute, rule or regulation, or of the
certificate or articles of incorporation or other constitutive documents or
by-laws of the Borrower or any Subsidiary, (B) any order of any Governmental
Authority or 
<PAGE>
 
                                                                              35

(C) any provision of any indenture, agreement or other instrument to which the
Borrower or any Subsidiary is a party or by which any of them or any of their
property is or may be bound, (ii) be in conflict with, result in a breach of or
constitute (alone or with notice or lapse of time or both) a default under, or
give rise to any right to accelerate or to require the prepayment, repurchase or
redemption of any obligation under any such indenture, agreement or other
instrument or (iii) result in the creation or imposition of any Lien upon or
with respect to any property or assets now owned or hereafter acquired by the
Borrower or any Subsidiary, other than (in the case of clauses (b)(i)(C) and
(ii) above) for such matters that, individually or in the aggregate, could not
reasonably be expected to have a Material Adverse Effect.

     SECTION 3.3. Enforceability. This Agreement has been duly executed and
delivered by the Borrower and constitutes, and each other Loan Document when
executed and delivered by the Borrower will constitute, a legal, valid and
binding obligation of the Borrower enforceable against the Borrower in
accordance with its terms, except as enforceability thereof may be limited by
bankruptcy, insolvency or similar laws of general application affecting
creditors' rights.

     SECTION 3.4. Governmental Approvals. No action, consent or approval of,
registration or filing with or any other action by any Governmental Authority is
or will be required in connection with the Transactions, except for such as have
been made or obtained and are in full force and effect.

     SECTION 3.5. Financial Statements. The Borrower has heretofore furnished to
the Lenders its consolidated balance sheets and statements of income,
shareholders' equity and cash flows (i) as of and for the fiscal year ended
December 30, 1995, audited by and accompanied by the opinion of BDO Seidman,
independent public accountants, and (ii) as of and for the fiscal quarter and
the portion of the fiscal year ended September 28, 1996, certified by a
Financial Officer. Such financial statements present fairly the financial
condition and results of operations of the Borrower and its consolidated
Subsidiaries as of such dates and for such periods. Such balance sheets and the
notes thereto disclose all material liabilities, direct or contingent, of the
Borrower and its consolidated Subsidiaries as of the dates thereof. Such
financial statements were prepared in accordance with GAAP applied on a
consistent basis, subject (in the case of the statements referred to in clause
(ii) above) to normal, year-end recurring adjustments.

     SECTION 3.6. No Material Adverse Change. There has been no material adverse
change in the business, assets, operations, prospects or condition, financial or
otherwise, of the Borrower and the Subsidiaries, taken as a whole, since
September 28, 1996.

Borrower and the Subsidiaries has good and marketable title to, or valid
leasehold interests in, all its material properties and assets. All such
material properties and assets are free and clear of Liens, other than Liens
expressly permitted by Section 6.2 granting to any Person any right to use,
occupy or enjoy such portion.
<PAGE>
 
                                                                              36

     (b) Each of the Borrower and the Subsidiaries has complied with all
obligations under all material leases to which it is a party, and all such
leases are in full force and effect. Each of the Borrower and the Subsidiaries
enjoys peaceful and undisturbed possession under all such material leases.

     SECTION 3.8. Subsidiaries. Schedule 3.8 sets forth as of the date hereof a
list of the Subsidiaries and the percentage ownership interest of the Borrower
therein. The shares of capital stock or other ownership interests so indicated
on Schedule 3.8 are fully paid and non-assessable and are owned by the Borrower,
directly or indirectly, free and clear of all Liens except under the Chase
Credit Facility.

     SECTION 3.9. Litigation; Compliance with Laws. (a) There are not any
actions, suits or proceedings at law or in equity or by or before any
Governmental Authority now pending or, to the knowledge of the Borrower,
threatened against or affecting any Loan Park or any business, property or
rights of any such Person (i) that involve any Loan Document or the Transactions
or (ii) as to which there is a likelihood of an adverse determination and that,
if adversely determined, could reasonably be expected, individually or in the
aggregate, to result in a Material Adverse Effect.

     (b) None of the Borrower and the Subsidiaries or any of their respective
material properties or assets is in violation of, nor will the continued
operation of such material properties and assets as currently conducted violate,
any law, rule or regulation (including any Health Care Law, any Environmental
Law, any zoning or building ordinance, code or approval or any building permit)
or any restriction of record or agreements affecting any such properties or
assets, or is in default with respect to any judgment, writ, injunction, decree
or order of any Governmental Authority, other than, in each case, such
violations and defaults that, individually and in the aggregate, could not
reasonably be expected to result in a Material Adverse Effect.

     SECTION 3.10. Agreements. (a) Neither the Borrower nor any Subsidiary is a
party to any agreement or instrument or subject to any corporate restriction
that has resulted or could reasonably be expected to result in a Material
Adverse Effect.

     (b) Neither the Borrower nor any of the Subsidiaries is in default in any
manner under any provision of any indenture or other agreement or instrument
evidencing Indebtedness, the General Shareholders Agreement dated September 30,
1994, as amended, and the Continuing Shareholders Agreement dated September 30,
1994, or any other agreement or instrument to which it is a party or by which it
or any of its properties or assets are or may be bound, other than such defaults
that, individually and in the aggregate, could not reasonably be expected to
result in a Material Adverse Effect.

     SECTION 3.11. Federal Reserve Regulations. (a) Neither the Borrower nor any
Subsidiary is engaged principally, or as one of its important activities, in the
business of extending credit for the purpose of buying or carrying Margin Stock.
<PAGE>
 
                                                                              37

     (b) No part of the proceeds of any Loan will be used, whether directly or
indirectly, and whether immediately, incidentally or ultimately, for any purpose
that entails a violation of, or that is inconsistent with, the provisions of the
Regulations of the Board, including, to the extent applicable, Regulation G. U
or X. Margin Stocks do not constitute 25% or more of the assets of the Borrower
and the Subsidiaries, taken as a whole.

     (c) No Indebtedness of the Borrower or any Subsidiary (other than the
Obligations) is "directly or indirectly secured" (within the meaning of
Regulation U and Regulation G) by any Margin Stock.

     SECTION 3.12. Investment Company Act; Public Utility Holding Company Act.
Neither the Borrower nor any Subsidiary is (a) an "investment company" as
defined in, or subject to regulation under, the Investment Company Act of 1940,
(b) a "holding company" as defined in, or subject to regulation under, the
Public Utility Holding Company Act of 1935 or (c) otherwise subject to any law,
rule or regulation that limits its ability to incur Indebtedness.

     SECTION 3.13. Use of Proceeds. The Borrower will use the proceeds of the
Loans to prepay the loans under the Chase Credit Agreement.

     SECTION 3.14. Tax Returns. Each of the Borrower and the Subsidiaries has
filed or caused to be filed all Federal, state, local and foreign tax returns or
materials required to have been filed by it and has paid or caused to be paid
all taxes due and payable by it and all assessments received by it, except taxes
that are being contested in good faith by appropriate proceedings and for which
the Borrower or such Subsidiary, as applicable, shall have set aside on its
books (in accordance with GAAP accounting requirements) adequate reserves.

     SECTION 3.15. No Material Misstatements. None of any information, report,
financial statement, exhibit or schedule authored by, and furnished by or on
behalf of, the Borrower in writing to the Administrative Agent or any Lender in
connection with the negotiation of any Loan Document or included therein or
delivered pursuant thereto contains any material misstatement of fact or omits
to state any material fact necessary to make the statements therein, in the
light of the circumstances under which they are made not misleading; provided.
however that to the extent any such information, report, financial statement,
exhibit or schedule was based upon or constitutes a forecast or projection, the
Borrower represents only that (x) it acted in good faith and utilized reasonable
assumptions and due care in the preparation of such information, report,
financial statement, exhibit or schedule and (y) with respect to projections
delivered by the Borrower to the Administrative Agent on December____, 1996, as
of the date of this Agreement and as of the Closing Date, the Borrower believes
the assumptions underlying such projections are reasonable.

     SECTION 3.16. Employee Benefit Plans. Each of the Borrower and the ERISA
Affiliates is in compliance in all respects with the applicable provisions of
ERISA and the Code and the regulations and published interpretations thereunder,
except for such failures to comply that, individually and in the aggregate,
could not reasonably be expected to result

 
<PAGE>
 
                                                                              38

in a Material Adverse Effect. No ERISA Event has occurred or is reasonably
expected to occur that, when taken together with all other such ERISA Events,
could reasonably be expected to result in a Material Adverse Effect. As of the
date of this Agreement, none of the Plans is a "defined benefit plan" as defined
in Section 3(35) of ERISA or Section 414(1) of the Code. The present value of
all benefit liabilities under each Plan (based on those assumptions used for
purposes of Statement of Financial Accounting Standards No. 87) did not, as of
the last annual valuation date applicable thereto, exceed by more than
$15,000,000 the fair market value of the assets of such Plan, and the present
value of all benefit liabilities of all underfunded Plans (based on those
assumptions used for purposes of Statement of Financial Accounting Standards No.
87) did not, as of the last annual valuation dates applicable thereto, exceed by
more than $15,000,000 the fair market value of the assets of all such
underfunded Plans.

     SECTION 3.17. Environmental Matters. (a) The properties owned or operated
by the Borrower and the Subsidiaries (the "Properties") do not contain any
Hazardous Materials in amounts or concentrations that constitute a violation of,
or could give rise to under, any Environmental Law, other than such violations
and liabilities that, individually and in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect.

     (b) The Properties and all operations of the Borrower and the Subsidiaries
are in compliance, and in the last six years have been in compliance, with all
Environmental Laws, and all Environmental Permits have been obtained and are in
effect, other than such items that, individually and in the aggregate, could not
reasonably be expected to result in a Material Adverse Effect.

     (c) There have not been any Releases or threatened Releases at, from, under
or, to the knowledge of the Borrower, proximate to the Properties or otherwise
in connection with the operations of the Borrower or the Subsidiaries, which
Releases or threatened Releases, in the aggregate, could reasonably be expected
to result in a Material Adverse Effect.

     (d) Neither the Borrower nor any Subsidiary has received any notice of an
Environmental Claim in connection with the Properties or the operations of the
Borrower or the Subsidiaries or with regard to any Person whose liabilities for
environmental matters the Borrower or the Subsidiaries has retained or assumed,
in whole or in part, contractually, or to the knowledge of the Borrower by
operation of law or otherwise, which, individually or in the aggregate, could
reasonably be expected to result in a Material Adverse Effect, nor do the
Borrower or the Subsidiaries have any knowledge that any such notice is likely
to be received or is being threatened.

     (e) Hazardous Materials have not been transported from the Properties, nor
have Hazardous Materials been generated, treated, stored or disposed of at, on
or under any Property in a manner that could reasonably be expected to give rise
to any material liability under any Environmental Law, nor has the Borrower or
Subsidiary retained or assumed any liability, contractually, or to the knowledge
of the Borrower by operation of law or otherwise,
<PAGE>
 
                                                                              39

with respect to the generation, treatment, storage or disposal of Hazardous
Materials, which transportation, generation, treatment, storage or disposal, or
retained or assumed liabilities, individually or in the aggregate, could
reasonably be expected to result in a Material Adverse Effect.

     SECTION 3.18. Insurance. Schedule 3.18 sets forth a true, complete and
correct of all insurance maintained by the Borrower and the Subsidiaries as of
the date hereof and the Closing Date. As of each such date, such insurance is in
full force and effect and all premiums due have been paid. The Borrower and the
Subsidiaries have insurance in such amounts and covering such risks and
liabilities as are in accordance with normal industry practice.

     SECTION 3.19. Solvency. (a) The fair salable value of the assets of the
Borrower and each Subsidiary exceeds the amount that will be required to be paid
on or in respect of the existing debts and other liabilities (including
contingent liabilities) of the Borrower or such Subsidiary as they mature.

     (b) The assets of the Borrower and each Subsidiary do not constitute
unreasonably small capital for the Borrower or such Subsidiary to carry out its
business as now conducted and as proposed to be conducted, including the capital
needs of the Borrower or such Subsidiary, taking into account the particular
capital requirements of the business conducted by the Borrower and each
Subsidiary, and the projected capital requirements and capital availability
thereof.

     (c) The Borrower and each Subsidiary do not intend to and shall not incur
debts beyond their respective ability to pay such debts as they mature taking
into account the timing and amounts of cash to be received by the Borrower and
such Subsidiary and of amounts to be payable on or in respect of obligations of
the Borrower and such Subsidiary. The cash flow of the Borrower and each
Subsidiary, after taking into account all anticipated uses of the cash of the
Borrower and each Subsidiary, will at all times be sufficient to pay all such
amounts on or in respect of debt of the Borrower or such Subsidiary when such
amounts are required to be paid.

     (d) The representations made in this Section 3.19 with respect to any
Subsidiary that is a Guarantor are made after taking into consideration and
giving effect to the Indemnity, Contribution and Subrogation Agreement.

     SECTION 3.20. Labor Matters. As of the date of this Agreement and the
Closing Date, there are no strikes, lockouts or slowdowns against the Borrower
or any Subsidiary pending or, to the knowledge of the Borrower, threatened. The
hours worked by and payments made to employees of the Borrower and the
Subsidiaries have not been in violation of the Fair Labor Standards Act or any
other applicable Federal, state, local or foreign law dealing with such matters.
All payments due from the Borrower or any Subsidiary, or for which any claim may
be made against the Borrower or any Subsidiary, on account of wages and employee
health and welfare insurance and other benefits, have been paid or accrued as a
liability on the books of the Borrower or such Subsidiary.

     SECTION 3.21. Capitalization of the Borrower. As of the date of this
Agreement, the authorized capital stock of the Borrower consists of 529,295
shares of common stock, par value $0.01 per share, of which 273,742 shares are
issued and outstanding. All such outstanding shares of stock are fully paid and
nonassessable.

     SECTION 3.22. Shareholders Agreements. The Administrative Agent has
received a complete copy of the General Shareholders Agreement dated September
30, 1994 and the Continuing Shareholders Agreement dated September 30, 1994
(including all exhibits, schedules and disclosure letters referred to therein or
delivered pursuant thereto) and all amendments and waivers relating thereto and
other side letters or agreements affecting the terms thereof.

                                   ARTICLE IV

                               Closing Conditions

declaration of acceleration in respect of such Indebtedness, and written notice
of such rescission shall have been given to the Administrative Agent by the
Borrower and countersigned by the holders of the Indebtedness that is the
subject of such acceleration or a trustee, fiduciary or agent for such holders,

conditions shall be satisfied:

Agreement has received notice may be used as a basis for any subsequent Payment
Bar Notice, unless such facts or circumstances have been cured or waived for a
period of not less than 90 consecutive days subsequent to the giving of the
initial Payment Bar Notice (it being acknowledged that any subsequent action or
breach that would give rise to a separate Senior Event of Default pursuant to

Subordinated Indebtedness prohibited under the foregoing provisions of this
Section 8.3(a)(i) (provided that such payments are not then prohibited under

unrescinded and unannulled, such Senior Indebtedness shall first be paid in full
in cash, or provision for such payment shall be made in a manner satisfactory to
the holders of such Senior Indebtedness, before any payment is made on account
of or applied on the Subordinated Indebtedness.

     (c) In the event that any payment of assets of the Borrower or any
Guarantor shall be received by any holder of Subordinated Indebtedness in
contravention of the foregoing provisions of this Section 8.3, such payment
shall be held in trust for the benefit of, and shall be immediately paid or
delivered by such holder to, as the case may be, the holders of such Senior
Indebtedness remaining unpaid, or their representative or representatives, for
application to the payment or prepayment of all such Senior Indebtedness
remaining unpaid, ratably according to the aggregate amounts remaining unpaid on
account of the Senior Indebtedness held or represented by each, to the extent
necessary to pay all such Senior Indebtedness in full in cash after giving

Rights of Holders of Senior Indebtedness. Subject to the payment in full in cash
of all Senior Indebtedness, the holders of Subordinated Indebtedness shall be
subrogated to the rights of the holders of Senior Indebtedness to receive
payments or distributions of assets of the Borrower or any Guarantor applicable
to the Senior Indebtedness until the Subordinated Indebtedness shall be paid in
full, and, for purposes of such subrogation, no payment or distribution to the
holders of the Senior Indebtedness of assets, whether in cash, Property or
securities, distributable to the holders of Senior Indebtedness under the
provisions hereof to which the holders of Subordinated Indebtedness would be
entitled except for the provisions of this Article VIII, and no payment pursuant
to the provisions of this Article VIII to the holders of Senior Indebtedness by
the holders of Subordinated Indebtedness shall, as between the Borrower and the
Guarantors, their creditors other than the holders of the Senior Indebtedness,
and the holders of the Subordinated Indebtedness, be deemed to be a payment by
the Borrower or any Guarantor to or on account of such Senior Indebtedness, it
being understood that the provisions of this Article VIII are, and are intended,
solely for the purpose of defining the relative rights of the holders of
Subordinated Indebtedness, on the one hand, and the holders of Senior
Indebtedness, on the other hand.

     SECTION 8.5. Obligations of the Borrower and the Guarantors Unconditional.
Nothing contained in this Article VIII or elsewhere in this Agreement is
intended to or shall impair, as between the Borrower and the Guarantors, and
their creditors other than the holders of Senior Indebtedness, the obligations
of the Borrower or any Guarantor to the holders of Subordinated Indebtedness to
pay any Subordinated Indebtedness as and when such Subordinated Indebtedness
shall become due and payable in accordance with its terms, or to affect the
relative rights of the holders of Subordinated Indebtedness and creditors of the
Borrower or any Guarantor other than the holders of Senior Indebtedness, nor
shall anything herein or therein prevent any holder of Subordinated Indebtedness
from exercising all remedies otherwise permitted by applicable law upon the
happening of an Event of Default under this Agreement subject to the rights, if
any, under this Article VIII of the holders of Senior Indebtedness in respect of
assets, whether in cash, Property or securities, paid or distributed by or on
behalf of the Borrower or any Guarantor and received upon the exercise of any
such remedy.

     This Article VIII is intended to establish the relative rights of the
holders of the Subordinated Indebtedness, on the one hand, and the holders of
Senior Indebtedness, on the other hand, and shall not be deemed to affect the
obligations of the Borrower or the Guarantors to the holders of Subordinated
Indebtedness.

     SECTION 8.6. Holders of Subordinated Indebtedness Entitled to Assume
Payments Not Prohibited in Absence of Notice. No holder of Subordinated
Indebtedness shall at any time be charged with knowledge of the existence of any
facts which would prohibit the making of any payment to it, unless and until the
Administrative Agent, on behalf of such holder, shall have received written
notice thereof at its principal office from the Borrower or any holder of Senior
Indebtedness or from a duly authorized agent or representative of the holders of
Senior Indebtedness (who shall be the Administrative Agent under the Chase
Credit Agreement); and prior to the receipt of any such written notice by the
Administrative Agent, on behalf of the holder of the Subordinated Indebtedness,
each such holder of the Subordinated Indebtedness shall be entitled to assume
conclusively that no such facts exist.

     Each holder of Subordinated Indebtedness shall be entitled to rely on the
delivery to it of a written notice by a Person representing himself to be a
holder of Senior Indebtedness or a duly authorized agent or representative of
the holders of Senior Indebtedness to establish that such notice has been given
by the holders of Senior Indebtedness or such duly authorized agent or
representative. In the event that such holder of Subordinated Indebtedness
determines in good faith that further evidence is required with respect to the
right of any holder of Senior Indebtedness to participate in any payment or
distribution pursuant to this Article VIII, such holder of Subordinated
Indebtedness may request such Person to furnish evidence to the reasonable
satisfaction of such holder of Subordinated Indebtedness as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article VIII, and if such
evidence is not furnished such holder of Subordinated Indebtedness may defer any
payment to such Person pending judicial determination as to the right of such
Person to receive such payment; provided that, upon the written request of such
Person to such holder, such payment shall be made to the court having
jurisdiction over such judicial determination or to another Person mutually
satisfactory to such Person and such holder, as escrowee, to be held and
invested pending such judicial determination in accordance with such
instructions as shall be mutually satisfactory to such Person and such holder
and upon such judicial determination becoming final and nonappealable to be
distributed in accordance therewith to the Person entitled thereto.

     SECTION 8.7. Effect of Failure to Pav Subordinated Indebtedness. The fact
that failure to make any payment on account of Subordinated Indebtedness is
prevented by reason of the operation of any provision of this Article VIII shall
not be construed as preventing the occurrence of an Event of Default under this
Agreement.

     SECTION 8.8. Miscellaneous Subordination Provisions. (a) The subordination
provisions contained herein are solely for the benefit of the holders from time
to time of Senior Indebtedness and their representatives, assignees and
beneficiaries and may not be rescinded, cancelled, amended or modified in any
way. No holder of Subordinated Indebtedness shall subordinate any Subordinated
Indebtedness to any indebtedness or obligation of the Borrower or any Guarantor
other than Senior Indebtedness.

                                                                              60

     (b) No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Borrower
or any Guarantor or by any act or failure to act, in good faith, by any such
holder, or by any non-compliance by the Borrower or any Guarantor with the
terms, provisions and covenants of this Agreement, regardless of any knowledge
thereof any such holder may have or be otherwise charged with.

     (c) Without in any way limiting the generality of paragraph (b) of this
Section, the holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to the holders of the Loans, without
incurring responsibility to the holders of the Loans and without impairing or
releasing the subordination provided in this Article VIII or the obligations
hereunder of the holders of the Loans to the holders of Senior Indebtedness, do
any one or more of the following: (1) change the manner, place or terms of
payment or extend the time of payment of, or renew or alter, Senior Indebtedness
or any instrument evidencing the same or any agreement under which Senior
Indebtedness is outstanding; (2) sell, exchange, release or otherwise deal with
any property pledged, mortgaged or otherwise securing Senior Indebtedness; (3)
release any Person liable in any manner for the collection of Senior
Indebtedness; and (4) exercise or refrain from exercising any rights against the
Borrower and any other Person.

     (d) The holders of Senior Indebtedness (and/or their designated agents or
representatives) are authorized to demand specific performance of the
subordination provisions contained herein. Each holder of Subordinated
Indebtedness irrevocably waives any defense based on the adequacy of a remedy at
law which might be asserted as a bar to such remedy of specific performance and
any requirement for the securing or posting of any bond in connection with such
remedy.

     (e) Each holder of Subordinated Indebtedness acknowledges and agrees that
the holders of Senior Indebtedness have relied upon and will continue to rely
upon the subordination provided for herein and hereby waives notice of or proof
of reliance hereon, demand for payment and notice of default.

     (f) The subordination provisions of this Article VIII shall, to the fullest
extent permitted by law, continue to be effective or be reinstated, as the case
may be, if at any time payment and performance of the Senior Indebtedness is,
pursuant to applicable law, avoided, recovered, or rescinded or must otherwise
be restored or returned by any holder of Senior Indebtedness, whether as a
"voidable preference," "fraudulent conveyance," "fraudulent transfer," or
otherwise, all as though such payment or performance had not been made.

                                   ARTICLE IX

                            The Administrative Agent

     To expedite the transactions contemplated by this Agreement, SocGen is
hereby appointed to act as Administrative Agent on behalf of the Lenders. Each
of the Lenders and
<PAGE>
 
                                                                              61

each assignee of any such Lender, hereby irrevocably authorizes the
Administrative Agent to take such actions on behalf of such Lender or assignee
and to exercise such powers as are specifically delegated to the Administrative
Agent by the terms and provisions hereof and of the other Loan Documents,
together with such actions and powers as are reasonably incidental thereto. The
Administrative Agent is hereby expressly authorized by the Lenders, without
hereby limiting any implied authority, (a) to receive on behalf of the Lenders
all payments of principal of and interest on the Loans and all other amounts due
to the Lenders hereunder, and promptly to distribute to each Lender its proper
share of each payment so received; (b) to give notice on behalf of each of the
Lenders to the Borrower of any Event of Default specified in this Agreement of
which the Administrative Agent has actual knowledge acquired in connection with
its agency hereunder; and (c) to distribute to each Lender copies of all
notices, financial statements and other materials delivered by the Borrower
pursuant to this Agreement as received by the Administrative Agent.

     Neither the Administrative Agent nor any of its respective directors,
officers, employees or agents shall be liable as such for any action taken or
omitted by any of them except for its or his own gross negligence or wilful
misconduct, or be responsible for any statement, warranty or representation
herein or the contents of any document delivered in connection herewith, or be
required to ascertain or to make any inquiry concerning the performance or
observance by the Borrower or any other Loan Party of any of the terms,
conditions, covenants or agreements contained in any Loan Document. The
Administrative Agent shall not be responsible to the Lenders for the due
execution, genuineness, validity, enforceability or effectiveness of this
Agreement or any other Loan Documents, instruments or agreements. The
Administrative Agent shall in all cases be fully protected in acting, or
refraining from acting, in accordance with written instructions signed by the
Required Lenders and, except as otherwise specifically provided herein, such
instructions and any action or inaction pursuant thereto shall be binding on all
the Lenders. The Administrative Agent shall, in the absence of knowledge to the
contrary, be entitled to rely on any instrument or document believed by it in
good faith to be genuine and correct and to have been signed or sent by the
proper person or persons. Neither the Administrative Agent nor any of its
respective directors, officers, employees or agents shall have any
responsibility to the Borrower or any other Loan Party on account of the failure
of or delay in performance or breach by any Lender of any of its obligations
hereunder or to any Lender on account of the failure of or delay in performance
or breach by any other Lender or the Borrower or any other Loan Party of any of
their respective obligations hereunder or under any other Loan Document or in
connection herewith or therewith. The Administrative Agent may execute any and
all duties hereunder by or through agents or employees and shall be entitled to
rely upon the advice of legal counsel selected by it with respect to all matters
arising hereunder and shall not be liable for any action taken or suffered in
good faith by it in accordance with the advice of such counsel.

     The Lenders hereby acknowledge that the Administrative Agent shall not be
under any duty to take any discretionary action permitted to be taken by it
pursuant to the provisions of this Agreement unless it shall be requested in
writing to do so by the Required Lenders. 
<PAGE>
 
                                                                              62

     Subject to the appointment and acceptance of a successor Administrative
Agent as provided below, the Administrative Agent may resign at any time by
notifying the Lenders and the Borrower. Upon any such resignation, the Required
Lenders shall have the right to appoint a successor with the prior approval of
the Borrower (such approval not to be unreasonably withheld or delayed). If no
successor shall have been so appointed by the Required Lenders and shall have
accepted such appointment within 30 days after the retiring Administrative Agent
gives notice of its resignation, then the retiring Administrative Agent may, on
behalf of the Lenders, appoint a successor Administrative Agent which shall be a
bank with an office in New York, New York, having a combined capital and surplus
of at least $500,000,000 or an Affiliate of any such bank. Upon the acceptance
of any appointment as Administrative Agent hereunder by a successor bank, such
successor shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent and the retiring
Administrative Agent shall be discharged from its duties and obligations
hereunder. After the Administrative Agent's resignation hereunder, the
provisions of this Article and Section 10.5 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Administrative Agent.

     With respect to the Loans made by it hereunder, the Administrative Agent in
its individual capacity and not as Administrative Agent shall have the same
rights and powers as any other Lender and may exercise the same as though it
were not the Administrative Agent, and the Administrative Agent and its
Affiliates may accept deposits from, lend money to and generally engage in any
kind of business with the Borrower or any Subsidiary or other Affiliate thereof
as if it were not the Administrative Agent.

     Each Lender agrees (a) to reimburse the Administrative Agent, on demand, in
the amount of its pro rata share (based on the principal amount of its Loan
outstanding on the date indemnification is sought) of any reasonable
out-of-pocket expenses incurred for the benefit of the Lenders by the
Administrative Agent, including counsel fees and compensation of agents and
employees paid for services rendered on behalf of the Lenders, that shall not
have been reimbursed by the Borrower and (b) to indemnify and hold harmless the
Administrative Agent and any of its directors, officers, employees or agents, on
demand, in the amount of such pro rata share, from and against any and all
liabilities, taxes, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever that
may be imposed on, incurred by or asserted against it in its capacity as
Administrative Agent or any of them in any way relating to or arising out of
this Agreement or any other Loan Document or any action taken or omitted by it
or any of them under this Agreement or any other Loan Document, to the extent
the same shall not have been reimbursed by the Borrower, provided, however, that
no Lender shall be liable to the Administrative Agent or any such other
indemnified person for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the gross negligence or wilful misconduct of the Administrative
Agent or any of its directors, officers, employees or agents. In the event the
Administrative Agent is subsequently reimbursed by any Loan Party for any such
expenses, liabilities, taxes, obligations, losses, damages, penalties,
judgments, costs or disbursements, the Administrative Agent shall reimburse each
Lender, pro rata, to the extent of any payment made by such Lender with respect
thereto under this paragraph.

     Each Lender acknowledges that it has, independently and without reliance
upon the Administrative Agent or any other Lender and based on such documents
and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Lender also acknowledges that it
will, independently and without reliance upon the Administrative Agent or any
other Lender and based on such documents and information as it shall from time
to time deem appropriate, continue to make its own decisions in taking or not
taking action under or based upon this Agreement or any other Loan Document, any
related agreement or any document furnished hereunder or thereunder.

     (c) By executing and delivering an Assignment and Acceptance, the assigning
Lender thereunder and the assignee thereunder shall be deemed to confirm to and
agree with each other and the other parties hereto as follows: (i) such
assigning Lender warrants that it is the legal and beneficial owner of the
interest being assigned thereby free and clear of any adverse claim and that the

Assignment and Acceptance, (ii) except as set forth in (i) above, such assigning
Lender makes no representation or warranty and assumes no responsibility with

connection with this Agreement, or the execution, legality, validity,
enforceability, genuineness, sufficiency or value of this Agreement, any other
Loan Document or any other instrument or document furnished pursuant hereto, or

information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement; (vi) such
assignee appoints and authorizes the Administrative Agent to take such action as
agent on its behalf and to exercise such powers under this Agreement as are
delegated to the Administrative Agent by the terms hereof, together with such
powers as are reasonably incidental thereto; and (vii) such assignee agrees that
it shall perform in accordance with their terms all the obligations which by the
terms of this Agreement are required to be performed by it as a Lender.

     (d) The Administrative Agent, acting for this purpose as an agent of the
Borrower, shall maintain at one of its offices in The City of New York a copy of
each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the principal amount
of the Loans owing to, each Lender pursuant to the terms hereof from time to
time (the "Register"). The entries in the Register shall be conclusive and the
Borrower, the Administrative Agent and the Lenders may treat each person whose
name is recorded in the Register pursuant to the terms hereof as a Lender
hereunder for all purposes of this Agreement, notwithstanding notice to the
contrary.

     (e) Upon its receipt of a duly completed Assignment and Acceptance executed
by an assigning Lender and an assignee, an Administrative Questionnaire
completed in respect of the assignee (unless the assignee shall already be a
Lender hereunder), the processing and
<PAGE>
 
                                                                              66

recordation fee referred to in paragraph (b) above and, if required, the written
consent of the Borrower and the Administrative Agent to such assignment, the
Administrative Agent shall (i) accept such Assignment and Acceptance and (ii)
record the information contained therein in the Register. No assignment shall be
effective unless it has been recorded in the Register as provided in this
paragraph (e).

     (f) Each Lender may without the consent of the Borrower or the
Administrative Agent sell participations to one or more banks or other entities
in all or a portion of its rights and obligations under this Agreement
(including all or a portion of the Loans owing to it); provided, however, that
(i) such Lender's obligations under this Agreement shall remain unchanged, (ii)
such Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (iii) each participating bank or other entity
shall be entitled to the benefit of the cost protection provisions contained in
Sections 2.14 and 2.18 to the same extent as if it were a Lender, but not in an
amount greater than that of the Lender from which it acquired its participation
(and any entitlement thereto of such participant shall reduce pro tanto the
right of such Lender to claim the benefit of such provisions), (iv) a
participation may not be offered or sold to any pharmaceutical company or to any
Affiliate of a pharmaceutical company and (v) the Borrower, the Administrative
Agent and the Lenders shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement, and such Lender shall retain the sole right to enforce the
obligations of the Borrower relating to the Loans and to approve any amendment,
modification or waiver of any provision of this Agreement (other than
amendments, modifications or waivers decreasing any fees payable hereunder or
the amount of principal of or the rate at which interest is payable on the Loans
or extending any scheduled principal payment date or date fixed for the payment
of interest on the Loans).

     (g) Notwithstanding Section 10.16, any Lender or participant may, in
connection with any assignment or participation or proposed assignment or
participation pursuant to this Section 10.4, disclose to the assignee or
participant or proposed assignee or participant any information relating to the
Borrower furnished to such Lender by or on behalf of the Borrower; provided,
however, that, prior to any such disclosure of information designated by the
Borrower as confidential, each such assignee or participant or proposed assignee
or participant shall execute an agreement (a copy of which shall be given to the
Borrower) whereby such assignee or participant shall agree to preserve the
confidentiality of such confidential information on terms no less restrictive
than those applicable to the Lenders pursuant to Section 10.16.

     (h) Any Lender may at any time assign all or any portion of its rights
under this Agreement or any note issued in connection herewith to a Federal
Reserve Bank to secure extensions of credit by such Federal Reserve Bank to such
Lender; provided, however, that no such assignment shall release a Lender from
any of its obligations hereunder or substitute any such Bank for such Lender as
a party hereto. In order to facilitate such an assignment to a Federal Reserve
Bank, the Borrower shall, at the request of the assigning Lender, duly execute
and deliver to the assigning Lender a promissory note or notes evidencing the
Loans made to the Borrower by the assigning Lender hereunder (each of
<PAGE>
 
                                                                              67

which promissory notes shall include a paragraph indicating that the obligations
evidenced thereby are subject to the provisions of Article VIII hereof).

     (i) The Borrower shall not assign or delegate any of its rights or duties
hereunder without the prior wriden consent of the Administrative Agent and each
Lender, and any attempted assignment without such consent shall be null and
void.

     SECTION 10.5. Expenses; Indemnity. (a) The Borrower shall pay all
reasonable out-of-pocket expenses reasonably incurred by the Administrative
Agent in connection with the syndication of the credit facilities provided for
herein and the preparation and administration of this Agreement and the other
Loan Documents or in connection with any amendments, modifications or waivers of
the provisions hereof or thereof (whether or not the transactions hereby or
thereby contemplated shall be consummated) or incurred during the continuance of
a Default by the Administrative Agent or any Lender in connection with the
enforcement or protection of its rights in connection with this Agreement and
the other Loan Documents or in connection with the Loans made hereunder,
including the reasonable fees, charges and disbursements of Simpson Thacher &
Bartlett, counsel for the Administrative Agent, and, in connection with any such
enforcement or protection, the reasonable fees, charges and disbursements of
such other special counsel for the Administrative Agent as the Administrative
Agent may deem necessary.

     (b) The Borrower shall indemnify the Administrative Agent, each Lender,
each Affiliate of any of the foregoing persons and each of their respective
directors, officers, employees and agents (each such person being called an
"indemnitee") against, and hold each Indemnitee harmless from, any and all
losses, claims, damages, liabilities and related expenses, including reasonable
counsel fees, charges and disbursements, incurred by or asserted against any
Indemnitee arising out of, in any way connected with, or as a result of (i) the
execution or delivery of this Agreement or any other Loan Document or any
agreement or instrument contemplated thereby, the performance by the parties
thereto of their respective obligations thereunder or the consummation of the
Transactions and the other transactions contemplated thereby (excluding, in the
case of each Indemnitee other than SocGen and its Affiliates, legal expenses
incurred prior to the date of this Agreement), (ii) the use of the proceeds of
the Loans, (iii) any claim, litigation, investigation or proceeding relating to
any of the foregoing, whether or not any Indemnitee is a party thereto or (iv)
any actual or alleged presence or Release of Hazardous Materials on any property
owned or operated by the Borrower or any Subsidiary, or any Environmental Claim
related in any way to the Borrower or the Subsidiaries; provided, however, that
such indemnity shall not, as to any Indemnitee, be available to the extent that
such losses, claims, damages, liabilities or related expenses are determined by
a court of competent jurisdiction by final and nonappealable judgment to have
resulted from the gross negligence or wilful misconduct of such Indemnitee.

     (c) The provisions of this Section 10.5 shall remain operative and in full
force and effect regardless of the expiration of the term of this Agreement, the
consummation of the transactions contemplated hereby, the repayment of any of
the Loans, the invalidity or unenforceability of any term or provision of this
Agreement or any other Loan Document, or

                                                                              68

any investigation made by or on behalf of the Administrative Agent or any
Lender. All amounts due under this Section 10.5 shall be payable on written
demand therefor.

     SECTION 10.6. Rights of Setoff. If an Event of Default shall have occurred
and be continuing, each Lender is hereby authorized at any time and from time to
time, to the fullest extent permitted by law, to set off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other indebtedness at any time owing by such Lender to or for the
credit or the account of the Borrower against any of and all the obligations of
the Borrower now or hereafter existing under this Agreement and other Loan
Documents held by such Lender, irrespective of whether or not such Lender shall
have made any demand under this Agreement or such other Loan Document and
although such obligations may be unmatured. The rights of each Lender under this
section are in addition to other rights and remedies (including other rights of
setoff) which such Lender may have.

     SECTION 10.7. Applicable Law. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS
SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF
NEW YORK.

     SECTION 10.8. Waivers; Amendment. (a) No failure or delay of the
Administrative Agent or any Lender in exercising any power or right hereunder or
under any other Loan Document shall operate as a waiver thereof, nor shall any
single or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Administrative Agent and the Lenders hereunder and under the
other Loan Documents are cumulative and are not exclusive of any rights or
remedies that they would otherwise have. No waiver of any provision of this
Agreement or any other Loan Document or consent to any departure by the Borrower
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) below, and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which given. No notice or demand
on the Borrower in any case shall entitle the Borrower to any other or further
notice or demand in similar or other circumstances.

     (b) Neither this Agreement nor any provision hereof may be waived, amended
or modified except pursuant to an agreement or agreements in writing entered
into by the Borrower and the Required Lenders; provided, however, that no such
agreement shall (i) decrease the principal amount of, or extend the maturity of
or any scheduled principal payment date or date for the payment of any interest
on any Loan, or waive or excuse any such payment or any part thereof, or
decrease the rate of interest on any Loan, without the prior written consent of
each Lender directly affected thereby, (ii) amend or modify the provisions of
Section 2.14 or 10.4(i), the provisions of this Section 10.8 or the definition
of the term "Required Lenders" without the prior written consent of each Lender,
(iii) release any Specified Guarantor without the prior written consent of
Lenders having Loans at such time representing at least 80% of the sum of all
Loans outstanding at such time or (iv) amend, modify or otherwise affect the
rights or duties of the Administrative Agent hereunder or under any other Loan
Document without the prior written consent of the Administrative Agent.

     SECTION 10.9. Interest Rate Limitation. Notwithstanding anything herein to
the contrary, if at any time the interest rate applicable to any Loan, together
with all fees, charges and other amounts which are treated as interest on such
Loan under applicable law (collectively the "Charges"), shall exceed the maximum
lawful rate (the "Maximum Rate") which may be contracted for, charged, taken,
received or reserved by the Lender holding such Loan or participation in
accordance with applicable law, the rate of interest payable in respect of such
Loan, together with all Charges payable in respect thereof, shall be limited to
the Maximum Rate, and, to the extent lawful, the interest and Charges that would
have been payable in respect of such Loan but were not payable as a result of
the operation of this Section shall be cumulated and the interest and Charges
payable to such Lender in respect of other Loans or periods shall be increased
(but not above the Maximum Rate therefor) until such cumulated amount, together
with interest thereon at the Federal Funds Effective Rate to the date of
repayment, shall have been received by such Lender.

     SECTION 10.10. Entire Agreement. This Agreement, the Fee Letter and the
other Loan Documents constitute the entire contract between the parties relative
to the subject matter hereof. Any other previous agreement among the parties
with respect to the subject matter hereof is superseded by this Agreement and
the other Loan Documents. Nothing in this Agreement or in the other Loan
Documents, expressed or implied, is intended to confer upon any party other than
the parties hereto and thereto and holders of Senior Indebtedness with respect
to Article VIII any rights, remedies, obligations or liabilities under or by
reason of this Agreement or the other Loan Documents.

     SECTION 10.11. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF,
UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS.
EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY
OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B)
ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS APPLICABLE, BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.11.

     SECTION 10.12. Severability. In the event any one or more of the provisions
contained in this Agreement or in any other Loan Document should be held
invalid, illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein and therein shall
not in any way be affected or impaired thereby. The parties shall endeavor in
good-faith negotiations to replace the invalid, illegal or unenforceable
provisions with valid provisions the economic effect of which comes as close as
possible to that of the invalid, illegal or unenforceable provisions.

     SECTION 10.13. Counterparts. This Agreement may be executed in counterparts
(and by different parties hereto on different counterparts), each of which shall
constitute an original but all of which when taken together shall constitute a
single contract, and shall become effective as provided in Section 10.3.
Delivery of an executed signature page to this Agreement by facsimile
transmission shall be as effective as delivery of a manually signed counterpart
of this Agreement.

     SECTION 10.14. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

     SECTION 10.15. Jurisdiction; Consent to Service of Process. (a) Each party
hereto hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
Federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement or the other Loan Documents, or for recognition or
enforcement of any judgment, and each party hereto hereby irrevocably and
unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. Each party hereto agrees that a final
judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Nothing in this Agreement shall affect any right that the
Administrative Agent or any Lender may otherwise have to bring any action or
proceeding relating to this Agreement or the other Loan Documents against the
Borrower or its properties in the courts of any jurisdiction.

     (b) Each party hereto hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement or the other Loan Documents in any
New York State or Federal court. Each party hereto hereby irrevocably waives, to
the fullest extent permitted by law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court.

     (c) Each party hereto irrevocably consents to service of process in the
manner provided for notices in Section 10.1. Nothing in this Agreement will
affect the right of any party to this Agreement to serve process in any other
manner permitted by law.

     SECTION 10.16. Confidentialiy. The Administrative Agent and each of the
Lenders agrees to keep confidential (and to use its best efforts to cause its
respective agents and representatives to keep confidential) the Information (as
defined below) and all copies thereof, extracts therefrom and analyses or other
materials based thereon, except that the Administrative Agent or any Lender
shall be permitted to disclose Information (a) to such of its respective
officers, directors, employees, agents, affiliates and representatives as need
to know such Information, (b) to the extent requested by any regulatory
authority, (c) to the extent otherwise required by applicable laws and
regulations or by any subpoena or similar

legal process, upon prior notice thereof (unless prohibited by the terms of such
subpoena or process) to the Borrower in a manner reasonably calculated to afford
the Borrower an opportunity to seek a protective order or other injunctive
relief, (d) in connection with any suit, action or proceeding relating to the
enforcement or protection of its rights hereunder or under the other Loan
Documents or (e) to the extent such Information (i) becomes publicly available
other than as a result of a breach of this Section 10.16 or (ii) becomes
available to the Administrative Agent or any Lender on a nonconfidential basis
from a source other than the Borrower. For the purposes of this Section 10.16,
"Information" shall mean all financial statements, certificates, reports,
agreements and information (including all analyses, compilations and studies
prepared by the Administrative Agent or any Lender based on any of the
foregoing) that are received from the Borrower and related to the Borrower, any
shareholder of the Borrower or any employee, customer or supplier of the
Borrower, other than any of the foregoing that were available to the
Administrative Agent or any Lender on a nonconfidential basis prior to its
disclosure thereto by the Borrower, and which are in the case of Information
provided after the date hereof, clearly identified at the time of delivery as
confidential. The provisions of this Section 10.16 shall remain operative and in
full force and effect regardless of the expiration and term of this Agreement.

of income or earnings relating thereto and the amount of Consolidated Interest
Expense associated with any Indebtedness incurred in connection therewith, the
pro forma calculations shall be determined in good faith by a responsible
financial or accounting Officer of the Company. If any Indebtedness bears a
floating rate of interest and is being given pro forma effect, the interest
expense on such Indebtedness shall be calculated as if the rate in effect on the
date of determination had been the applicable rate for the entire period (taking
into account any Interest Rate Agreement applicable to such Indebtedness if such
Interest Rate Agreement has a remaining term in excess of 12 months).

     "Consolidated Interest Expense" means, for any period, the total interest

Preferred Stock of Restricted Subsidiaries of the Company and Disqualified
Capital Stock of the Company held by Persons other than the Company or a
Restricted Subsidiary multiplied by (b) a fraction, the numerator of which is
one and the denominator of which is one minus the then current combined federal,
state and local statutory tax rate of the Company, expressed as a decimal, in
each case, determined on a consolidated basis in accordance with GAAP.

     "Consolidated Net Income" means, for any period, the net income (loss) of
the Company and its consolidated Restricted Subsidiaries; provided, however,
that there shall not be included in such Consolidated Net Income: (i) any net
income (loss) of any Person if such Person is not a Restricted Subsidiary,

Company's equity in the net income of any such Person for such period shall be
included in such Consolidated Net Income up to the aggregate amount of cash
actually distributed by such Person during such period to the Company or a
Restricted Subsidiary as a dividend or other distribution (subject, in the case
of a dividend or other distribution to a Restricted Subsidiary, to the
limitations contained in clause (iii) below); (ii) any net income (loss) of any
person acquired by the Company or a Restricted Subsidiary in a pooling of
interests transaction for any period prior to the date of such acquisition;

Subsidiary is subject to restrictions, directly or indirectly, on the payment of
dividends or the making of distributions by such Restricted Subsidiary, directly
or indirectly, to the Company, except that subject to the limitations contained
in (iv) below, the Company's equity in the net income of any such Restricted
Subsidiary for such period shall be included in such Consolidated Net Income up
to the aggregate amount of cash that could have been distributed by such
Restricted Subsidiary during such period to the Company or another Restricted
Subsidiary as a dividend

Restricted Subsidiary, to the limitation contained in this clause); (iv) any
gain or loss realized upon the sale or other disposition of any assets of the
Company or its consolidated Restricted Subsidiaries which are not sold or
otherwise disposed of in the ordinary course of business and any gain or loss
realized upon the sale or other disposition of any Capital Stock of any Person;

Directors of the Company in the manner provided below and which remains so
designated at the time of determination. The Board of Directors of the Company
may, by a Board resolution delivered to the Trustee, designate any Restricted
Subsidiary of the Company (other than a Material Subsidiary) (including any
newly acquired or newly formed Subsidiary of the Company) to be an Unrestricted
Subsidiary unless such Restricted Subsidiary owns any Capital Stock of, or holds
any Lien on any property of, the Company or any Restricted Subsidiary, and
provided no Default or Event of Default shall have occurred and be continuing at
the time of or after giving effect to such designation. The Board of Directors
of the Company may designate any Unrestricted Subsidiary to be a Restricted
Subsidiary of the Company, provided that (i) no Default or Event of Default
shall have occurred and be continuing at the time of or after giving effect to
such designation and (ii) all Liens and Indebtedness of such Unrestricted
Subsidiary outstanding immediately following such designation would, if incurred
at such time, have been permitted to be incurred for all purposes of this
Indenture. Any designation by the Board of Directors of the Company pursuant to
this Indenture shall be evidenced to the Trustee by promptly filing with the
Trustee a copy of the Board resolutions giving effect to such designation and an
Officer's Certificate certifying that such designation complied with the
foregoing provisions.

     "Voting Shares" of a Person means all classes of Capital Stock of such
Person then outstanding and normally entitled to vote in the election of
directors or managers.

     "Weighted Average Life to Maturity" means, when applied to any Indebtedness
or Disqualified Capital Stock, as the case may be, at any date, the number of
years obtained by dividing (a) the sum of the products obtained by multiplying
(x) the amount of each then remaining installment, sinking fund, serial maturity
or other required payments of principal, including payment at final maturity, in
respect thereof, by (y) the number of years (calculated to the nearest
one-twelfth) that will elapse between such date and the making of such payment,
by (b) the then outstanding principal amount or liquidation preference, as
applicable, of such Indebtedness or Disqualified Capital Stock, as the case may
be.

                           ISSUE, EXECUTION, FORM AND
                          REGISTRATION OF SECURITIES.

     SECTION 2.1 Authentication and Delivery of Securities Upon the execution
and delivery of this Indenture, or from time to time thereafter, Securities in
an aggregate principal amount not to exceed $103,500,000 (except as otherwise
provided in Section 2.6) may be executed by the Company and delivered to the
Trustee for authentication, and the Trustee shall thereupon authenticate and
deliver said Securities to or upon the written order of the Company, signed by
both (a) any senior executive officer of the Company and (b) by its chief
financial officer, principal accounting officer, Controller, Treasurer or any
Assistant Treasurer or its Secretary or any Assistant Secretary without any
further action by the Company.

                                                                              19


     SECTION 2.2 Execution of Securities. The Securities shall be signed on
behalf of the Company by both (a) any senior executive officer of the Company
and (b)by its chief financial officer, principal accounting officer, Controller,
Treasurer or any Assistant Treasurer or its Secretary or any Assistant
Secretary, under its corporate seal. Such signatures may be the manual or
facsimile signatures of the present or any future such officers. The corporate
seal of the Company may be in the form of a facsimile thereof and may be
impressed, affixed, imprinted or otherwise reproduced on the Securities and may,
but need not, be attested. Typographical and other minor errors or defects in
any such reproduction of the seal or any such signature shall not affect the
validity or enforceability of any Security which has been duly authenticated and
delivered by the Trustee.

     In case any officer of the Company who shall have signed any of the
Securities shall cease to be such officer before the Security so signed shall be
authenticated and delivered by the Trustee or disposed of by the Company, such
Security nevertheless may be authenticated and delivered or disposed of as
though the person who signed such Security had not ceased to be such officer of
the Company; and any Security may be signed on behalf of the Company by such
persons as, at the actual date of the execution of such Security, shall be the
proper officers of the Company, although at the date of the execution and
delivery of this Indenture any such person was not such officer.

     SECTION 2.3 Certificate of Authentication. Only such Securities as shall
bear thereon a certificate of authentication substantially in the form
hereinbefore recited, executed by the Trustee by manual signature of one of its
authorized officers, shall be entitled to the benefits of this Indenture or be
valid or obligatory for any purpose. Such certificate by the Trustee upon any
Security executed by the Company shall be conclusive evidence that the Security
so authenticated has been duly authenticated and delivered hereunder and that
the holder is entitled to the benefits of this Indenture.

     SECTION 2.4 Form, Denomination and Date of Securities; Payments of
Interest. (a) The Initial Notes and the Trustee's certificate of authentication
shall be substantially in the form of Exhibit A hereto, and the Conversion Notes
and the Trustee's certificate of authentication shall be in substantially the
form of Exhibit B hereto, each of which is part of this Indenture. The
Securities shall be numbered, lettered, or otherwise distinguished in such
manner or in accordance with such plans as the officers of the Company executing
the same may determine with the approval of the Trustee. Any of the Securities
may be issued with appropriate insertions, omissions, substitutions and
variations, and may have imprinted or otherwise reproduced thereon such legend
or legends, not inconsistent with the provisions of this Indenture, as may be
required to comply with any law or with any rules or regulations pursuant
thereto, or with the rules of any securities market in which the Securities are
admitted to trading, or to conform to general usage. All Securities shall be
otherwise substantially identical expect as to denomination and as provided
herein.

     Each Security shall be dated the date of its authentication, shall bear
interest from the applicable date, and shall be payable on the dates specified
on the face of the form of Security recited above.

                                                                              20


     The Person in whose name any Security is registered at the close of
business on any record date with respect to any interest payment date shall be
entitled to receive the interest, if any, payable on such interest payment date
notwithstanding any transfer or exchange of such Security subsequent to the
record date and prior to such interest payment date, except if and to the extent
that the Company shall default in the payment of the interest due on such
interest payment date, in which case such defaulted interest shall be paid to
the Persons in whose names outstanding Securities are registered at the close of
business on a subsequent record date (which shall be not less than five business
days prior to the date of payment of such defaulted interest) established by
notice given by mail by or on behalf of the Company to the holders of Securities
not less than 15 days preceding such subsequent record date. The term "record
date" as used with respect to any interest payment date (except a date for
payment of defaulted interest) shall mean if such interest payment date is the
first day of a calendar month, the fifteenth day of the next preceding calendar
month and shall mean, if such interest payment date is the fifteenth day of a
calendar month, the first day of such calendar month, whether or not such record
date is a business day.

     (b)The Initial Notes are being offered and sold by the Company pursuant to
the Loan Agreement. The Initial Notes offered and sold to QIBs in reliance on
Rule 144A, except as provided in Section 2.4(d) hereof, shall be issued
initially in the form of one or more permanent global Securities in definitive,
fully registered form without interest coupons with the Global Securities Legend
and Restricted Securities Legend set forth in the form of Initial Notes (the
"Restricted Global Security") deposited with the Trustee, at the Corporate Trust
Office, as custodian for and registered in the name of the Depository or a
nominee of the Depository, duly executed by the Company and authenticated by the
Trustee as hereinafter provided. The aggregate principal amount of the
Restricted Global Security may from time to time be increased or decreased by
adjustments made on the records of the Trustee and the Depository or its nominee
as hereinafter provided.

     (c) This Section 2.4(c) shall apply only to the Restricted Global Security
deposited with or on behalf of the Depository.

     Members of, or participants in, the Depository (the "Agent Members") shall
have no rights under this Indenture with respect to any Restricted Global
Security held on their behalf by the Depository or under the Restricted Global
Security, and the Depository may be treated by the Company, the Trustee, and any
agent of the Company or the Trustee as the absolute owner of the Restricted
Global Security for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by the Depository or impair, as between the
Depository and its Agent Members, the operation of customary practices governing
the exercise of the rights of a holder of any Security.

     (d) Except as provided in this Section 2.4(d) and Section 2.8, owners of
beneficial interests in the Restricted Global Security will not be entitled to
receive physical delivery of certificated Initial Notes. Purchasers of Initial
Notes who are not QIBs or QIBs who elect to receive certificated Initial Notes
instead of holding their interest through the
<PAGE>
 
                                                                              21

Restricted Global Security (collectively, the "Non-Global Purchasers") will
receive certificated Initial Notes bearing the Restricted Securities Legend (the
"Restricted Securities"); provided, however, that upon transfer to a QIB of any
such certificated Initial Notes initially issued to a Non-Global Purchaser, such
certificated Initial Notes will, unless the transferee requests otherwise or the
Restricted Global Security has previously been exchanged in whole for Restricted
Securities, be exchanged for an interest in the Restricted Global Security
pursuant to the provisions of Section 2.5. Restricted Securities will bear the
Restricted Securities Legend unless removed in accordance with Section 2.5.

     Upon the occurrence of an Effective Registration involving a Notes Shelf
Registration, all requirements with respect to the Restricted Global Security
and legends on Initial Notes will cease to apply, and certificated Initial Notes
without the Restricted Securities Legend will be available to the Holders. Upon
the occurrence of an Effective Registration involving the Registered Exchange
Offer, all requirements with respect to the Restricted Global Security will
cease to apply and certificated Initial Notes with the "Restricted Securities
Legend" will be available to Holders that do not exchange their Initial Notes
for Conversion Notes, and certificated Conversion Notes without any legends will
be available to Holders that exchange their Initial Notes for Conversion Notes.

     All certificated Securities shall be issuable in denominations of $1,000
principal amount and any integral multiple thereof.

     SECTION 2.5 Registration, Transfer and Exchange. (a) The Company will keep
at each office or agency to be maintained for the purpose as provided in Section
3.2 a register or registers in which, subject to such reasonable regulations as
it may prescribe, it will register, and will register the transfer of,
Securities as in this Article provided. Such register shall be in written form
in the English language or in any other form capable of being converted into
such form within a reasonable time. At all reasonable times such register or
registers shall be open for inspection by the Trustee.

     Upon due presentation for registration of transfer of any Security at each
such office or agency, the Company shall execute and the Trustee shall
authenticate and deliver in the name of the transferee or transferees a new
Security or Securities in authorized denominations for a like aggregate
principal amount.

     Any Security or Securities may be exchanged for a Security or Securities in
other authorized denominations, in an equal aggregate principal amount.
Securities to be exchanged shall be surrendered at each office or agency to be
maintained by the Company for the purpose as provided in Section 3.2. and the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor the Security or Securities which the Securityholder making the exchange
shall be entitled to receive, bearing numbers not contemporaneously outstanding.

     All Securities presented for registration of transfer, exchange, redemption
or payment shall (if so required by the Company or the Trustee) be duly endorsed
by, or be accompanied by a written instrument or instruments of transfer in form
satisfactory to the
<PAGE>
 
                                                                              22


Company and the Trustee duly executed by, the holder or his attorney duly
authorized in writing.

     The Company may require payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection with any exchange or
registration of transfer of Securities. No service charge shall be made for any
such transaction.

     The Trustee shall not be required to exchange or register a transfer of (a)
any Securities for a period of 15 days next preceding the first mailing of
notice of redemption of Securities to be redeemed or (b) any Securities
selected, called or being called for redemption except, in the case of any
Security where public notice has been given that such Security is to be redeemed
in part, the portion thereof not so to be redeemed.

     All Securities issued upon any transfer or exchange of Securities shall be
valid obligations of the Company, evidencing the same debt, and entitled to the
same benefits under this Indenture, as the Securities surrendered upon such
transfer or exchange.

     (b) Notwithstanding any provision to the contrary herein, so long as the
Restricted Global Security remains outstanding and is held by or on behalf of
the Depository, transfers of the Restricted Global Security, in whole or in
part, shall only be made in accordance with Section 2.4(d) and this Section 2.5
as set forth below.

          (i) Subject to clauses (ii) through (iv) below, transfers of the
     Restricted Global Security shall be limited to transfers of the Restricted
     Global Security in whole, but not in part, to nominees of the Depository or
     to a successor of the Depository or such successor's nominee.

          (ii) Restricted Global Security to Restricted Security. If a holder of
     a beneficial interest in the Restricted Global Security deposited with the
     Depository wishes at any time to transfer its interest therein to a Person
     who wishes to take delivery thereof in the form of a Restricted Security,
     such holder may, subject to the rules and procedures of the Depository,
     cause the exchange of such interest for one or more Restricted Securities
     of any authorized denomination or denominations and of the same aggregate
     principal amount. Upon receipt by the Trustee at its Corporate Trust Office
     of (l) instructions from the Depository directing the Trustee to
     authenticate and deliver one or more Restricted Securities of the same
     aggregate principal amount as the beneficial interest in the Restricted
     Global Security to be exchanged, such instructions to contain the name or
     names of the designated transferee or transferees, the authorized
     denomination or denominations of the Restricted Securities to be so issued
     and appropriate delivery instructions, (2) a certificate in the form of
     Exhibit C attached hereto given by the holder of such beneficial interest
     and stating that the Person transferring such interest in the Restricted
     Global Security reasonably believes that the Person acquiring the
     Restricted Securities for which such interest is being exchanged is an
     Institutional Accredited Investor and is acquiring such Restricted
     Securities for its own account or for one or more accounts as to which
<PAGE>
 
                                                                              23


     the transferee exercises sole investment discretion, (3) a certificate in
     the form of Exhibit D attached hereto given by the Person acquiring the
     Restricted Securities for which such interest is being exchanged, to the
     effect set forth therein, and (4) an opinion of counsel to the holder of
     such beneficial interest in the form of Exhibit E attached hereto, to the
     effect set forth therein, then the Trustee will instruct the Depository to
     reduce the Restricted Global Security by the aggregate principal amount of
     the beneficial interest therein to be exchanged, and concurrently with such
     reduction the Company shall execute, and the Trustee shall authenticate and
     deliver, one or more Restricted Securities of the same aggregate principal
     amount, in accordance with the instructions referred to above.

          (iii) Restricted Securitv to Restricted Global Security. If a holder
     of a Restricted Security wishes at any time to transfer such Restricted
     Security to a Person who wishes to take delivery thereof in the form of an
     interest in the Restricted Global Security, such holder may, subject to the
     rules and procedures of the Depository, cause the exchange of such
     Restricted Security for an equivalent beneficial interest in the Restricted
     Global Security. Upon receipt by the Trustee at its Corporate Trust Office
     of (1) such Restricted Security, duly endorsed as provided herein, (2)
     instructions from such holder directing the Trustee to credit or cause to
     be credited a beneficial interest in the Restricted Global Security equal
     to the principal amount of the Restricted Security to be exchanged, such
     instructions to contain information regarding the participant account with
     the Depository to be credited with such interest, and (3) a certificate in
     the form of Exhibit F attached hereto, then the Trustee shall cancel or
     cause to be cancelled such Restricted Security and shall instruct the
     Depository to credit or cause to be credited to the account of the Person
     specified in such instructions a beneficial interest in the Restricted
     Global Security equal to the principal amount of the Restricted Security so
     cancelled.

          (iv) Restricted Securitv to Restricted Security. If a holder of a
     Restricted Security wishes at any time to transfer such Restricted Security
     to a Person who wishes to take delivery thereof in the form of a Restricted
     Security, such holder may, subject to the restrictions on transfer set
     forth herein and in such Restricted Security, cause the exchange of such
     Restricted Securities for one or more Restricted Securities of any
     authorized denomination or denominations and of the same aggregate
     principal amount. Upon receipt by the Trustee at its Corporate Trust Office
     of (1) such Restricted Security, duly endorsed as provided herein, (2)
     instructions from such holder directing the Trustee to authenticate and
     deliver one or more Restricted Securities of the same aggregate principal
     amount as the Restricted Security to be exchanged, such instructions to
     contain the name or names of the designated transferee or transferees, the
     authorized denomination or denominations of the Restricted Securities to be
     so issued and appropriate delivery instructions, (3) a certificate from the
     holder of the Restricted Security to be exchanged in the form of Exhibit C
     attached hereto (in the event that the transfer is being made to an
     Institutional Accredited Investor otherwise than pursuant to Rule 144A),
     (4) a certificate in the form of Exhibit D attached hereto (in the event
     the transfer is being made to an Institutional Accredited Investor
     otherwise than pursuant to Rule 144A) given by the
<PAGE>
 
                                                                              24


     Person acquiring the Restricted Securities for which such interest is being
     exchanged, to the effect set forth therein, and (5) an opinion of counsel
     to the transferor of such Restricted Security in the form of Exhibit E
     hereto, to the effect set forth therein, then the Trustee shall cancel or
     cause to be cancelled such Restricted Security and, concurrently therewith,
     the Company shall execute, and the Trustee shall authenticate and deliver,
     one or more Restricted Securities of the same aggregate principal amount,
     in accordance with the instructions referred to above.

          (v) Other Exchanges. In the event that the Restricted Global Security
     is exchanged pursuant to Section 2.8 for Securities in definitive
     registered form without interest coupons, prior to an Effective
     Registration such Initial Notes may be exchanged for one another only in
     accordance with those procedures that are substantially consistent with the
     provisions of clauses (i) through (iv) above (including the certification
     requirements thereof intended to insure that such transfers comply with the
     Securities Act) and which may be from time to time adopted by the Company
     and the Trustee.

     If Initial Notes are issued upon the transfer, exchange or replacement of
Initial Notes bearing the Restricted Securities Legend, or if a request is made
to remove such Restricted Securities Legend on Initial Notes, the Initial Notes
so issued shall bear the Restricted Securities Legend, or the Restricted
Securities Legend shall not be removed, as the case may be, unless (i) there is
delivered to the Company such satisfactory evidence, which may include an
opinion of counsel licensed to practice law in the State of New York, as may be
reasonably required by the Company that neither the legend nor the restrictions
on transfer set forth therein are required to ensure that transfers thereof
comply with the provisions of the Securities Act or, with respect to Restricted
Securities, that such Initial Notes are not "restricted" within the meaning of
Rule 144 under the Securities Act or (ii) there is an Effective Registration
involving the Notes Shelf Registration with respect to the Initial Notes then in
effect or the Initial Note as to which the Restricted Securities Legend is
sought to be removed has been disposed of in accordance with the Notes Shelf
Registration. Upon (i) provision of such satisfactory evidence or (ii)
notification by the Company to the Trustee of an Effective Registration with
respect to the Initial Notes, the Trustee, at the direction of the Company,
shall authenticate and deliver Initial Notes that do not bear the Restricted
Securities Legend.

     SECTION 2.6 Mutilated, Defaced, Destroyed, Lost and Stolen Securities. In
case any temporary or definitive Security shall become mutilated, defaced or be
apparently destroyed, lost or stolen, the Company in its discretion may execute,
and upon the written request of any officer of the Company, the Trustee shall
authenticate and deliver, a new Security, bearing a number not contemporaneously
outstanding, in exchange and substitution for the mutilated or defaced Security,
or in lieu of and substitution for the Security so apparently destroyed, lost or
stolen. In every case the applicant for a substitute Security shall furnish to
the Company and to the Trustee and any agent of the Company or the Trustee such
security or indemnity as may be required by them to indemnify and defend and to
save each of them harmless and, in every case of destruction, loss or theft
evidence to their satisfaction of the apparent destruction, loss or theft of
such Security and of the ownership thereof.
<PAGE>
 
                                                                              25


     Upon the issuance of any substitute Security, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses (including the fees
and expenses of the Trustee) connected therewith. In case any Security which has
matured or is about to mature, or has been called for redemption in full, shall
become mutilated or defaced or be apparently destroyed, lost or stolen, the
Company may, instead of issuing a substitute Security, pay or authorize the
payment of the same (without surrender thereof except in the case of a mutilated
or defaced Security), if the applicant for such payment shall furnish to the
Company and to the Trustee and any agent of the Company or the Trustee such
security or indemnity as any of them may require to save each of them harmless
from all risks, however remote, and, in every case of apparent destruction, loss
or theft, the applicant shall also furnish to the Company and the Trustee and
any agent of the Company or the Trustee evidence to their satisfaction of the
apparent destruction, loss or theft of such Security and of the ownership
thereof.

     Every substitute Security issued pursuant to the provisions of this Section
by virtue of the fact that any Security is apparently destroyed, lost or stolen
shall constitute an additional contractual obligation of the Company, whether or
not the apparently destroyed, lost or stolen Security shall be at any time
enforceable by anyone and shall be entitled to all the benefits of (but shall be
subject to all the limitations of rights set forth in) this Indenture equally
and proportionately with any and all other Securities duly authenticated and
delivered hereunder. All Securities shall be held and owned upon the express
condition that, to the extent permitted by law, the foregoing provisions are
exclusive with respect to the replacement or payment of mutilated, defaced, or
apparently destroyed, lost or stolen Securities and shall preclude any and all
other rights or remedies notwithstanding any law or statute existing or
hereafter enacted to the contrary with respect to the replacement or payment of
negotiable instruments or other securities without their surrender.

     SECTION 2.7 Cancellation of Securities; Destruction Thereof. All Securities
surrendered for payment, redemption, registration of transfer or exchange, if
surrendered to the Company or any agent of the Company or the Trustee, shall be
delivered to the Trustee for cancellation or, if surrendered to the Trustee,
shall be cancelled by it; and no Securities shall be issued in lieu thereof
except as expressly permitted by any of the provisions of this Indenture. The
Trustee shall deliver cancelled Securities held by it to the Company. If the
Company shall acquire any of the Securities, such acquisition shall not operate
as a redemption or satisfaction of the indebtedness represented by such
Securities unless and until the same are delivered to the Trustee for
cancellation.

     SECTION 2.8 Temporary Securities; Global Securities. Pending the
preparation of definitive Securities, the Company may execute and the Trustee
shall authenticate and deliver temporary Securities (printed, lithographed,
typewritten or otherwise reproduced, in each case in form satisfactory to the
Trustee). Temporary Securities shall be issuable as registered Securities
without coupons, of any authorized denomination, and substantially in the form
of the definitive Securities but with such omissions, insertions and variations
as may be appropriate for temporary Securities, all as may be determined by the
Company with the concurrence of the Trustee. Temporary Securities may contain
such
<PAGE>
 
                                                                              26


reference to any provisions of this Indenture as may be appropriate. Every
temporary Security shall be executed by the Company and be authenticated by the
Trustee upon the same conditions and in substantially the same manner, and with
like effect, as the definitive Securities. Without unreasonable delay, the
Company shall execute and shall furnish definitive Securities and thereupon
temporary Securities may be surrendered in exchange therefor without charge at
each office or agency to be maintained by the Company for the purpose pursuant
to Section 3.2, and the Trustee shall authenticate and deliver in exchange for
such temporary Securities a like aggregate principal amount of definitive
Securities of authorized denominations. Until so exchanged the temporary
Securities shall be entitled to the same benefits under this Indenture as
definitive Securities.

     The Restricted Global Security deposited with the Depository pursuant to
Section 2.4 shall be transferred to the beneficial owners thereof only if such
transfer complies with Section 2.5(b) of this Indenture and (i) the Depository
notifies the Company that it is unwilling or unable to continue as Depository
for the Restricted Global Security or if at any time such Depository ceases to
be a "clearing agency" registered under the Exchange Act and a successor
depositary is not appointed by the Company within 90 days of such notice, (ii)
the Company executes and delivers to the Trustee an Officer's Certificate
stating that such Global Restricted Security shall be exchangeable, or (iii) an
Event of Default has occurred and is continuing with respect to the Securities.

     Any Restricted Global Security that is transferable to the beneficial
owners thereof pursuant to this Section 2.8 shall be surrendered by the
Depository to the Trustee at its Corporate Trust Office, to be so transferred,
in whole or from time to time in part, without charge, and the Trustee shall
authenticate and deliver, upon such transfer of each portion of such Restricted
Global Security, an equal aggregate principal amount of Restricted Securities of
authorized denominations. Any portion of the Restricted Global Security
transferred pursuant to this Section 2.8 shall be executed, authenticated and
delivered only in denominations of $1,000 and any integral multiple thereof and
registered in such names as the Depository shall direct. Any Initial Note
delivered in exchange for an interest in the Restricted Global Security shall,
except as otherwise provided by Section 2.5, bear the Restricted Securities
Legend.

     Subject to the foregoing provisions of this Section 2.8, the registered
Holder of a Global Security may grant proxies and otherwise authorize any
Person, including Agent Members and Persons that may hold interests through
Agent Members, to take any action which a Holder is entitled to take under this
Indenture or the Securities.

     In the event of the occurrence of either of the events specified in the
second paragraph of this Section 2.8, the Company will promptly make available
to the Trustee a reasonable supply of certificated Securities in definitive,
fully registered form without interest coupons.

     SECTION 2.9 Effective Registration. In the event the Company has an
Effective Registration, the Company shall notify the Trustee thereof within two
Business Days after the effective date of such Effective Registration. If the
Effective Registration involves a
<PAGE>
 
                                                                              27


Notes Shelf Registration, the Company shall promptly cause to be delivered to
the Trustee certificates for Initial Notes without legends and the Trustee shall

not be required to make an offer for Securities pursuant to this Section 3.10 if
the Net Available Cash available therefor (aver application of the proceeds as
provided in clauses (A), (B) and (C)) is less than $15,000,000 (which lesser
amount shall be carried forward for purposes of determining whether an offer is
required with respect to the Net Available Cash from any subsequent Asset
Disposition).

elect to have his or her Securities purchased by the Company either in whole or
in part (subject to prorating as hereinafter described in the event the Offer is
oversubscribed) in integral multiples of $1,000 of principal amount, at the
applicable purchase price. The notice shall specify a purchase date not less
than 30 days nor more than 60 days after the date of such notice (the "Purchase
Date").

          (ii) Not later than the date upon which such written notice of an
     Offer is delivered to the Trustee and the Holders, the Company shall
     deliver to the Trustee an Officers' Certificate setting forth (A) the
     amount of the Offer (the "Offer Amount"), (B) the allocation of the Net
     Available Cash from the Asset Dispositions as a result of which such Offer
     is being made and (C) the compliance of such allocation with the provisions
     of Section 3.10(a). Upon the expiration of the period (the "Offer Period")
     for which the Offer remains open, the Company shall deliver to the Trustee
     for cancellation the Securities or portions thereof which have been
     properly tendered to and are to be accepted by the Company. The Trustee
     shall, on the Purchase Date, mail or deliver payment to each tendering
     Holder in the amount of the purchase price of the Securities tendered by
     such Holder to the extent such funds are available to the Trustee.

          (iii) Holders electing to have a Security purchased will be required
     to surrender the Security, with an appropriate form duly completed, to the
     Company at
<PAGE>
 
                                                                              36


     the address specified in the notice prior to the expiration of the Offer
     Period. Each Holder will be entitled to withdraw its election if the
     Trustee or the Company receives, not later than one Business Day prior to
     the expiration of the Offer Period, a telegram, telex, facsimile
     transmission or letter from such Holder setting forth the name of such
     Holder, the principal amount of the Security or Securities which were
     delivered for purchase by such Holder and a statement that such Holder is
     withdrawing its election to have such Security or Securities purchased. If
     at the expiration of the Offer Period the aggregate principal amount of
     Securities surrendered by Holders exceeds the Offer Amount, the Company
     shall select the Securities to be purchased on a pro rata basis (with such
     adjustments as may be deemed appropriate by the Company so that only
     Securities in denominations of $1,000, or integral multiples thereof, shall
     be purchased). Holders whose Securities are purchased only in part will be
     issued new Securities equal in principal amount to the unpurchased portion
     of the Securities surrendered.

     (d) The Company shall comply with the applicable tender offer rules,
including Rule 14e-1 under the Exchange Act, and any other securities laws or
regulations in connection with the repurchase of Securities pursuant to this
Section 3.10.

     To the extent that the provisions of any securities laws or regulations
conflict with provisions of this Section 3.10, the Company will comply with the
applicable securities laws and regulations and will not be deemed to have
breached its obligations under this Indenture by virtue thereof.

     SECTION 3.11 Limitation on Restrictions on Distributions from Restricted
Subsidiaries. The Company shall not, and shall not permit any Restricted
Subsidiary to, create or otherwise cause or permit to exist or become effective

Stock or pay any Indebtedness owed to the Company or any Restricted Subsidiary,
(b) to make any loans or advances to the Company or any Restricted Subsidiary or
(c) to transfer any of its property or assets to the Company or any Restricted
Subsidiary, except: (i) any encumbrance or restriction pursuant to an agreement
in effect at or entered into on the Issue Date; (ii) any encumbrance or
restriction with respect to a Restricted Subsidiary pursuant to an agreement
relating to any Indebtedness incurred by such Restricted Subsidiary on or prior
to the date on which such Restricted Subsidiary was acquired by the Company
(other than Indebtedness incurred as consideration in, or to provide all or any
portion of the funds or credit support utilized to consummate, the transaction
or series of related transactions pursuant to which such Restricted Subsidiary
became a Restricted Subsidiary or was acquired by the Company) and outstanding
on such date; (iii) any encumbrance or restriction pursuant to an agreement
effecting a refinancing of Indebtedness incurred pursuant to an agreement
referred to in clause (i) or (ii) of this Section 3.11 or contained in any
amendment to an agreement referred to in clause (i) or (ii) of this Section 3.1
1; provided, however, that the encumbrances and restrictions with respect to
such Restricted Subsidiary contained in any such refinancing agreement or
amendment are no less favorable in any material respect to the holders of the
Securities than encumbrances and restrictions with respect to such Restricted
Subsidiary contained in such agreements; and (iv)
<PAGE>
 
                                                                              37


in the case of Section 3.11(c), any encumbrance or restriction (A) that
restricts in a customary manner the subletting, assignment or transfer of any
property or asset that is a lease, license, conveyance or contract or similar
property or asset that is the subject of such encumbrance or restriction, (B)
existing by virtue of any transfer of, agreement to transfer, option or right
with respect to, or Lien on, any property or assets of the Company or any
Restricted Subsidiary not otherwise prohibited by this Indenture, or (C) arising
or agreed to in the ordinary course of business, not relating to any
Indebtedness, and that do not, individually or in the aggregate, detract from
the value of property or assets of the Company or any Restricted Subsidiary in
any manner material to the Company or any Restricted Subsidiary; provided that,
in each case, such encumbrance or restriction relates to, and restricts dealings
with, only the property or asset that is the subject of such encumbrance or
restriction; and provided further, that such encumbrance or restriction does not
prohibit, limit or otherwise restrict the making or payment of any dividend or
other distribution to the Company or any Restricted Subsidiary; (v) any
restriction with respect to a Restricted Subsidiary imposed pursuant to an
agreement entered into for the sale or disposition of all or substantially all
the Capital Stock or assets of such Restricted Subsidiary pending the closing of

net worth imposed by customers under contracts entered into in the ordinary
course of business.

     SECTION 3.12 Limitation on Sale of Capital Stock of Restricted
Subsidiaries. The Company (i) shall not, and shall not permit any Restricted
Subsidiary to, transfer, convey, sell or otherwise dispose of any Capital Stock
of any Restricted Subsidiary to any Person (other than to the Company or a
Restricted Subsidiary) and (ii) shall not permit any Restricted Subsidiary to
issue any of its Capital Stock to any Person other than to the Company or a
Restricted Subsidiary; provided, however, that this Section 3.12 shall not
prohibit the transfer, conveyance, sale or other disposition of all of the
Capital Stock of a Restricted Subsidiary if the net cash proceeds from such
transfer, conveyance, sale or other disposition are applied in accordance with
Section 3.10; and, provided, further, that this Section 3.12 shall not prohibit
the transfer, conveyance, sale or other disposition of less than all of the
Capital Stock of a Restricted Subsidiary or the issuance by any Restricted
Subsidiary of any of its Capital Stock to any Person as long as (A) the net cash
proceeds from such transfer, conveyance, sale or other disposition or issuance
are applied in accordance with Section 3.10, (B) immediately after giving effect
to such transaction, no Event of Default shall have occurred and be continuing,
(C) immediately after giving pro forma effect to such transaction, as if such
transaction had occurred at the beginning of the applicable four-quarter period,
the Company would be permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Consolidated Coverage Ratio test as set forth in
Section 3.8(a) and (D) immediately after giving effect to such transaction, such
Restricted Subsidiary remains a Restricted Subsidiary of the Company.

     SECTION 3.13 Limitation on Liens. The Company shall not, and shall not
permit any Restricted Subsidiary to, directly or indirectly, incur, assume or
suffer to exist any Lien of any kind upon any of its property or assets
(including any shares of Capital Stock or Indebtedness of any Restricted
Subsidiary), whether owned on the Issue Date or acquired after the Issue Date,
or any income or profits therefrom, except if the Securities (or the Guarantee
of the Securities, in the case of Liens on properties or assets of any
Guarantor) and all other

obligation or liability secured by such Lien, excluding, however, from the
operation of the foregoing any of the following:

     (a) any Lien existing as of the Issue Date;

     (b) any Lien arising by reason of (i) any judgment, decree or order of any

responsible insurance companies; (ii) taxes, assessments or other governmental
charges that are not yet delinquent or are being contested in good faith; (iii)

respect to leasehold interests, mortgages, obligations, liens and other
encumbrances incurred, created, assumed or permitted to exist and arising by,
through or under a landlord or owner of the leased property, with or without
consent of the lessee), none of which materially impairs the use of any property
or assets material to the operation of the business of the Company or any
Restricted Subsidiary or the value of such property or assets for the purpose of
such business; (vi) deposits to secure public or statutory obligations, or in
lieu of surety or appeal bonds with respect to matters not yet finally

proceedings that suspend the collection thereof; or (vii) operation of law in
favor of mechanics, materialmen, laborers, employees or suppliers, incurred in
the ordinary course of business for sums that are not yet delinquent or are

to any other Person in the ordinary course of business;

     (f) Liens in the nature of trustees' Liens granted pursuant to any
indenture governing any indebtedness permitted by Section 3.8, in each case in
favor of the trustee under such indenture and securing only obligations to pay
any compensation to such trustee, to reimburse its expenses and to indemnify it
under the terms thereof; and
<PAGE>
 
                                                                              39


     (g)any extension, renewal, refinancing or replacement, in whole or in part,
of any Lien described in the foregoing clauses (a) through (f) so long as the
amount of property or assets subject to such Lien is not increased thereby.

     SECTION 3.14 Limitations on Affiliate Transactions. (a) The Company shall
not, and shall not permit any Restricted Subsidiary to, directly or indirectly,
enter into or conduct any transaction (including the purchase, sale, lease or
exchange of any property or the rendering of any service) with any Affiliate of
the Company (an "Affiliate Transaction") unless: (i) the terms of such Affiliate
Transaction are no less favorable to the Company or such Restricted Subsidiary,
as the case may be, than those that could be obtained at the time of such
transaction in arm's-length dealings with a Person who is not such an Affiliate;
(ii) in the event such Affiliate Transaction involves an aggregate amount in
excess of $1,000,000 (unless such Affiliate Transaction constitutes an agreement
with Bayer or its Affiliate relating to an investment by the Company and an
investment by Bayer or its Affiliate in a Permitted Foreign Company in which
case the requirements of this clause shall be applicable only if the amount
being invested by the Company exceeds $10,000,000), the terms of such
transaction have been approved by a majority of the members of the Board of
Directors of the Company and by a majority of the disinterested members of such
Board, if any (and such majority or majorities, as the case may be, determines
that such Affiliate Transaction satisfies the criteria in (i) above) and (iii)
in the event such Affiliate Transaction involves an aggregate amount in excess
of $15,000,000 (unless such Affiliate Transaction constitutes an agreement with
Bayer or its Affiliate relating to an investment by the Company and an
investment by Bayer or its Affiliate in a Permitted Foreign Company in which
case the requirements of this clause shall be applicable only if the amount
being invested by the Company exceeds $25,000,000), the Company has received a
written opinion from an independent investment banking firm of nationally
recognized standing that such Affiliate Transaction is fair to the Company or
such Restricted Subsidiary, as the case may be, from a financial point of view.

     (b) The provisions of Section 3.14(a) will not prohibit (i) any Restricted
Payment permitted to be paid or made pursuant to Section 3.9, (ii) the
performance of the Company's or a Restricted Subsidiary's obligations under any
employment contract, stock option, collective bargaining agreement, employee
benefit plan, related trust agreement or any other similar arrangement
heretofore or hereafter entered into in the ordinary course of business, (iii)
payment of compensation to employees, officers, directors or consultants in the
ordinary course of business, (iv) maintenance in the ordinary course of business

between the Company and a Restricted Subsidiary or between Restricted
Subsidiaries, (vi) any agreement in effect as of the Issue Date or any amendment
thereto or any transaction contemplated thereby, (vii) transactions required of
the Company or any Restricted Subsidiary under, or contemplated by, the General
Shareholders Agreement dated September 30, 1994, and the Continuing Shareholders
Agreement dated September 30, 1994, in each case as in effect on the date of
this Indenture or (viii) any agreement entered into in the ordinary course of
business between the Company and a person who constitutes an Affiliate solely by
reason of such person being an officer or director of the Company which
agreement provides for the repurchase by the Company, upon or following
<PAGE>
 
                                                                              40


the termination of such person's employment or directorship with the Company, of
shares of Capital Stock of the Company owned by such person.

     SECTION 3.15 Chance of Control. (a) If a Change of Control shall occur at
any time, then each holder of Securities shall have the right to require that
the Company purchase such holder's Securities in whole or in part in any
integral multiple of $1,000, for a cash purchase price (the "Change of Control
Purchase Price") equal to 101% of the principal amount of such Securities, plus
accrued and unpaid interest, if any, on such Securities to the date of purchase
(the "Change of Control Purchase Date"), pursuant to an offer (the "Change of
Control Offer"), made in conformity with the procedures set forth in Sections
3.15(b), (c) and (d).

     (b) Within 15 days following any Change of Control, the Company shall
notify the Trustee thereof and give written notice of such Change of Control to
each holder of Securities by first-class mail, postage prepaid, at his address
appearing in the security register, stating:

          (i) that a Change of Control has occurred and that such Holder has the
     right to require the Company to purchase such Holder's Securities, in whole
     or in part, at the Change of Control Purchase Price;

          (ii) the Change of Control Purchase Price and the Change of Control
     Purchase Date, which shall be a Business Day no earlier than 30 days nor
     later than 60 days from the date such notice is mailed, or such later date
     as is necessary to comply with requirements under the Exchange Act;

          (iii) that any Security not tendered for purchase will continue to
     accrue interest;

          (iv) that, unless the Company defaults in the payment of the Change of
     Control Purchase Price, any Securities accepted for payment pursuant to the
     Change of Control Offer shall cease to accrue interest after the Change of
     Control Purchase Date; and

          (v) the procedures that a Holder must follow to accept a Change of
     Control Offer or to withdraw such acceptance.

     (c) Holders electing to have Securities purchased will be required to
surrender such Securities, together with the execution form provided for on
Exhibit G duly executed, to the Company at the address specified in the notice
at least 10 Business Days prior to the Change of Control Purchase Date. Holders
will be entitled to withdraw their election if the Company receives, not later
than three Business Days prior to the Change of Control Purchase Date, a
facsimile transmission or letter setting forth the name of the Holder, the
principal amount of the Securities delivered for purchase by the Holder as to
which his election is to be withdrawn and a statement that such Holder is
withdrawing his election to have such Securities purchased. Holders whose
Securities are purchased only in part will be

                                                                              41


issued new Securities equal in principal amount to the unpurchased portion of
the Securities surrendered.

     (d) The Company will comply with any applicable tender offer rules,
including Rule 14e-1 under the Exchange Act, and any other applicable securities
laws or regulations in connection with a Change of Control Offer. To the extent
that the provisions of any securities laws or regulations conflict with
provisions of this Section, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under this Section by virtue thereof.

     (e) The Company will not, and will not permit any Subsidiary to, create or
permit to exist or become effective any restriction (other than restrictions in
effect on the Issue Date with respect to Indebtedness outstanding on the Issue
Date and refinancings thereof and customary default provisions) that would
materially impair the ability of the Company to make a Change of Control Offer
to purchase the Securities or, if such Change of Control Offer is made, to pay
for the Securities tendered for purchase.

     SECTION 3.16 Limitation on Lines of Business. The Company shall not, and
shall not permit its Restricted Subsidiaries to, engage in any business other
than those engaged in on the date of this Indenture and any other segment of the
pharmaceutical or health-care industry or ancillary thereto.

     SECTION 3.17 Payments for Consent. Neither the Company nor any Subsidiary
shall, directly or indirectly, pay or cause to be paid any consideration,
whether by way of interest, fee or otherwise, to any Holder of the Securities
for or as an inducement to any consent, waiver or amendment of any terms or
provisions of the Securities unless such consideration is offered to be paid or
agreed to be paid to all Holders of the Securities who so consent, waive or
agree in the time frame set forth in the solicitation documents relating to such
consent, waiver or agreement.

     SECTION 3.18 Waiver of Stay, Extension or Usury Laws. The Company covenants
(to the extent that it may lawfully do so) that it will not at any time insist
upon, plead, or in any manner whatsoever claim, and will resist any and all
efforts to be compelled to take the benefit or advantage of, any stay or
extension law or any usury law or other law that would prohibit or forgive the
Company from paying all or any portion of the principal of or interest on the
Securities as contemplated herein, wherever enacted, now or at any time
hereafter in force, or which may affect the covenants or the performance of this
Indenture; and (to the extent that it may lawfully do so) the Company hereby
waives all benefit or advantage of any such law, and covenants that it will not
hinder, delay or impede the execution of any power herein granted to the
Trustee, but will suffer and permit the execution of every such power as though
no such law had been enacted.

                             DEFAULTS AND REMEDIES

     SECTION 4.1 Event of Default Defined; Acceleration of Maturity. An "Event
of Default" occurs if:

     (a) the Company defaults in any payment of interest on any Security when
the same becomes due and payable, whether or not such payment shall be
prohibited by Article X, and such default continues for a period of 30 days;

Securities when required pursuant to Section 3.10 or 3.15, which failure shall
constitute an Event of Default under Section 4.1(b)) and such failure continues
for 30 days after the notice specified below;

     (e) the Company fails to comply with any covenant, condition or agreement
in this Indenture or the Securities (other than those referred to in clauses
(a), (b), (c) and (d) above) and such failure continues for 30 days after the
notice specified below;

     (f) Indebtedness of the Company or any Restricted Subsidiary is not paid
within any applicable grace period after final maturity or is accelerated by the
holders thereof because of a default and the total amount of such unpaid or
accelerated Indebtedness exceeds $10,000,000 or its foreign currency equivalent
at the time;

     (g) the Company or a Material Subsidiary pursuant to or within the meaning
of any Bankruptcy Law:

          (i) commences a voluntary case;

          (ii) consents to the entry of an order for relief against it in an
     involuntary case;

          (iii) consents to the appointment of a Custodian of it or for any
     substantial part of its property; or

          (iv) makes a general assignment for the benefit of its creditors;

or takes any comparable action under any foreign laws relating to insolvency;
<PAGE>
 
                                                                              43


     (h) a court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that:

          (i) is for relief against the Company or any Material Subsidiary in an
     involuntary case;

          (ii) appoints a Custodian of the Company or any Material Subsidiary or
     for any substantial part of its property; or

          (iii) orders the winding up or liquidation of the Company or any
     Material Subsidiary;

any Subsidiary Guarantor of its obligations hereunder or any Subsidiary
Guarantee if such failure is not cured, or such denial or disaffirmation is not
rescinded or revoked, within 10 days.

     The foregoing will constitute Events of Default whatever the reason for any
such Event of Default and whether it is voluntary or involuntary or is effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body.

     The term "Bankruptcy Law" means Title 11, United States Code, or any
similar Federal or state law for the relief of debtors. The term "Custodian"
means any receiver, trustee, assignee, liquidator, custodian or similar official
under any Bankruptcy Law.

     Notwithstanding the foregoing, a Default under Section 4.1(d) or Section
4.1(e) will not constitute an Event of Default until the Trustee or the Holders
of at least 25% in principal amount of the outstanding Securities notify the
Company in writing of the Default and the Company does not cure such Default
within the time specified in said Section 4.1(d) or (e) after receipt of such
notice. Such notice must specify the Default, demand that it be remedied, and
state that such notice is a "Notice of Default."

     An Event of Default specified in Section 4.1(f) and all consequences
thereof (including without limitation, any acceleration or resulting payment
default) shall be annulled,
<PAGE>
 
                                                                              44


waived and rescinded, automatically and without any action by the Trustee or the
Holders of the Securities, if within 20 days after the occurrence of such Event
of Default, (i) the holders of the Indebtedness to which such Event of Default
relates have rescinded or waived the acceleration, notice or action (as the case
may be) giving rise to such Event of Default or (ii) the default that is the
basis for such Event of Default has been cured.

     The Company shall deliver to the Trustee: (i) within 5 days after the
occurrence thereof, written notice in the form of an Officer's Certificate of
any Event of Default under clause (f) and any event which with the giving of
notice or the lapse of time would become an Event of Default under clause (d),
(e) or (i), its status and what action the Company is taking or proposes to take
with respect thereto and (ii) within 120 days after the end of each fiscal year,
written notice in the form of an Officer's Certificate indicating whether the
Officers signing such Officer's Certificate had actual knowledge of any Default
that occurred during such previous fiscal year.

     SECTION 4.2 Acceleration. If an Event of Default (other than an Event of
Default specified in Section 4.1(g) or (h) with respect to the Company) occurs
and is continuing, the Trustee, by notice to the Company, or the Holders of at
least 25% in outstanding principal amount of the Securities, by notice to the
Company and the Trustee, may declare the principal of, and accrued and unpaid
interest on, all the Securities to be due and payable. Upon such a declaration,
such principal and interest shall be due and payable (i) if no Indebtedness is
outstanding under the Senior Credit Agreement, immediately, and (ii) if any
Indebtedness is outstanding under the Senior Credit Agreement, upon the first to
occur of (x) the acceleration of any such Indebtedness or (y) the fifth Business
Day after receipt by the Company and the Credit Agent of such written notice of
acceleration. If an Event of Default specified in Section 4.1(g) or (h) with
respect to the Company occurs and is continuing, the principal of, and accrued
and unpaid interest on, all the Securities shall into facto become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holders. The Holders of a majority in principal amount of the
Securities, by notice to the Trustee, may rescind an acceleration and its
consequences if the rescission would not conflict with any judgment or decree
and if all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of
acceleration. No such rescission shall affect any subsequent Default or Event of
Default or impair any right consequent thereto.

     SECTION 4.3 Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the Securities or to enforce the performance of
any provision of the Securities or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default. No remedy shall be deemed
exclusive of any other remedy and all available remedies shall be cumulative.

     SECTION 4.4 Waiver of Past Defaults. The Holders of a majority in
outstanding principal amount of the Securities, by notice to the Trustee, may
waive an existing Default or Event of Default and its consequences except (i) a
Default or Event of Default in the payment of the principal of or interest on a
Security or (ii) a Default or Event of Default in respect of a provision that
under Section 7.2 cannot be amended without the consent of each Holder affected.
When a Default or Event of Default is waived, it is deemed cured, but no such
waiver shall extend to any subsequent or other Default or Event of Default or
impair any consequent right.

     SECTION 4.5 Control by Majority. The Holders of a majority in outstanding
principal amount of the Securities may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture or,
subject to Section 5.1, that the Trustee determines is unduly prejudicial to the
rights of other Holders (it being understood that, subject to Section 5.1, the
Trustee shall have no duty to ascertain whether or not such actions or
forbearances are unduly prejudicial to such Holders) or would subject the
Trustee to personal liability; provided, however, that the Trustee may take any
other action deemed proper by the Trustee that is not inconsistent with such
direction. Prior to taking or refraining from taking any such action hereunder,
the Trustee shall be entitled to indemnification satisfactory to it in its sole
discretion against all losses and expenses caused by its taking or refraining
from taking such action.

     SECTION 4.6 Limitation on Suits. A Holder may not pursue any remedy with
respect to this Indenture or the Securities unless:

     (a) the Holder gives to the Trustee written notice stating that an Event of
Default is continuing;

     (b) the Holders of at least 25% in outstanding principal amount of the
Securities make a written request to the Trustee to pursue the remedy;

     (c) such Holder or Holders offer to the Trustee reasonable security or
indemnity against any loss, liability or expense;

     (d) the Trustee does not comply with the request within 60 days after
receipt of the request and the offer of security or indemnity; and

     (e) the Holders of a majority in principal amount of the Securities do not
give the Trustee a direction inconsistent with the request during such 60-day
period.

     A Holder may not use this Indenture to prejudice the rights of another
Holder or to obtain a preference or priority over another Holder.

                                                                              46


     SECTION 4.7 Rights of Holders to Receive Payment. Notwithstanding any other
provision of this Indenture, the right of any Holder to receive payment of the
principal of and interest on the Securities held by such Holder on or after the
respective due dates expressed in the Securities, or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.

     SECTION 4.8 Collection Suit by Trustee. If an Event of Default specified in
Section 4.1(a) or (b) occurs and is continuing, the Trustee may recover judgment
in its own name and as trustee of an express trust against the Company for the
whole amount then due and owing (together with interest on any unpaid interest
to the extent lawful) and the amounts provided for in Section 5.6.

     SECTION 4.9 Trustee May File Proofs of Claim. The Trustee may file such
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee and the Holders allowed in any
judicial proceedings relative to the Company, its Subsidiaries or their
respective creditors or properties and, unless prohibited by law or applicable
regulations, may vote on behalf of the Holders in any election of a trustee in
bankruptcy or other Person performing similar functions, and any Custodian in
any such judicial proceeding is hereby authorized by each Holder to make
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and its counsel, and any other amounts due
the Trustee under Section 5.6.

     SECTION 4.10 Priorities. If the Trustee collects any money or property
pursuant to this Article IV, it shall pay out the money or property in the
following order:

          FIRST: Costs and expenses of collection, including all sums paid or
     advanced by the Trustee hereunder and the reasonable compensation, expenses
     and disbursements of the Trustee, its agents, and counsel and all other
     amounts due to the Trustee under Section 5.6;

          SECOND: To holders of Senior Indebtedness to the extent required by
     Article X;

          THIRD: To Holders for amounts due and unpaid on the Securities for
     principal and interest, without preference or priority of any kind,
     according to the amounts due and payable on the Securities for principal
     and interest, respectively; and

          FOURTH: To the Company.

     The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 4.10. At least 15 days before such record date,
the Company shall mail to each Holder and the Trustee a notice that states the
record date, the payment date and the amount to be paid.

     SECTION 4.11 Undertaking for Costs. In any suit for the enforcement of any
right or remedy under this Indenture or in any suit against the Trustee for any
action taken or omitted by it as Trustee, a court in its discretion may require
the filing by any party litigant in the suit of an undertaking to pay the costs
of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in the suit,
having due regard to the merits and good faith of the claims or defenses made by
the party litigant. This Section 4.11 does not apply to a suit by the Trustee, a
suit by a Holder pursuant to Section 4.7 or a suit by Holders of more than 10%
in outstanding principal amount of the Securities.

                                    ARTICLE V

                             CONCERNING THE TRUSTEE

     SECTION 5.1 Duties and Responsibilities of the Trustee; During Default;
Prior to Default. The Trustee, prior to the occurrence of an Event of Default
and after the curing or waiving of all Events of Default that may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture. In case an Event of Default has occurred that has not
been cured or waived, the Trustee shall exercise such of the rights and powers
vested in it by this Indenture, and use the same degree of care and skill in
their exercise, as a prudent man would exercise or use under the circumstances
in the conduct of his own affairs. The Trustee shall not be charged with
knowledge of the existence of an Event of Default, other than with respect to a
payment default, unless and until the Trustee has actual knowledge of such Event
of Default or the Trustee shall have received notice thereof in writing from the
Company or from the holders of a majority in principal amount of the Securities.

     No provision of this Indenture shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or
its own wilful misconduct, except that

     (a) prior to the occurrence of an Event of Default and after the curing or
waiving of all such Events of Default that may have occurred:

          (i) the duties and obligations of the Trustee shall be determined
     solely by the express provisions of this Indenture, and the Trustee shall
     not be liable except for the performance of such duties and obligations as
     are specifically set forth in this Indenture, and no implied covenants or
     obligations shall be read into this Indenture against the Trustee; and

          (ii) in the absence of bad faith on the part of the Trustee, the
     Trustee may conclusively rely, as to the truth of the statements and the
     correctness of the opinions expressed therein, upon any statements,
     certificates or opinions furnished to the Trustee and conforming to the
     requirements of this Indenture; but in the case of any such statements,
     certificates or opinions that are specifically required by any proving
<PAGE>
 
                                                                              48


     hereof to be furnished to the Trustee, the Trustee shall be under a duty to
     examine the same to determine whether or not they conform to the
     requirements of this Indenture;

     (b) the Trustee shall not be liable for any error of judgment made in good
faith by a responsible officer or responsible officers of the Trustee, unless it
shall be proved that the Trustee was negligent in ascertaining the pertinent
facts; and

     (c) the Trustee shall not be liable with respect to any action taken or
omitted to be taken by it in good faith in accordance with the direction of the
holders of not less than a majority in principal amount of the Securities at the
time outstanding relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred upon the Trustee, under this Indenture.

     None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there shall be reasonable ground for believing that the
repayment of such funds or adequate indemnity against such liability is not
reasonably assured to it.

     This Section 5.1 is in furtherance of and subject to Sections 315 and 316
of the Trust Indenture Act.

     SECTION 5.2 Certain Rights of the Trustee. In furtherance of and subject to
the Trust Indenture Act, and subject to Section 5.1:

     (a) the Trustee may rely and shall be protected in acting or refraining
from acting upon any resolution, Officer's Certificate or any other certificate,
statement, instrument, opinion, report, notice, request, consent, order, bond,
debenture, note, coupon, security or other paper or document believed by it to
be genuine and to have been signed or presented by the proper party or parties;

     (b) any request, direction, order or demand of the Company mentioned herein
shall be sufficiently evidenced by an Officer's Certificate (unless other
evidence in respect thereof be herein specifically prescribed); and any
resolution of the Board of Directors may be evidenced to the Trustee by a copy
thereof certified by the secretary or an assistant secretary of the Company;

     (c) the Trustee may consult with counsel and any advice or Opinion of
Counsel shall be full and complete authorization and protection in respect of
any action taken, suffered or omitted to be taken by it hereunder in good faith
and in reliance on such advice or Opinion of Counsel;

     (d) the Trustee shall be under no obligation to exercise any of the trusts
or powers vested in it by this Indenture at the request, order or direction of
any of the Securityholders pursuant to the provisions of this Indenture, unless
such Securityholders shall
<PAGE>
 
                                                                              49

have offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which might be incurred therein or thereby;

     (e) the Trustee shall not be liable for any action taken or omitted by it
in good faith and believed by it to be authorized or within the discretion,
rights or powers conferred upon it by this Indenture;

     (f) prior to the occurrence of an Event of Default hereunder and after the
curing or waiving of all Events of Default, the Trustee shall not be bound to
make any investigation into the facts or matters stated in any resolution,
certificate, statement, instrument, opinion, report, notice, request, consent,
order, approval, appraisal, bond, debenture, note, coupon, security, or other
paper or document unless requested in writing to do so by the holders of not
less than a majority in aggregate principal amount of the Securities then
outstanding; provided that, if the payment within a reasonable time to the
Trustee of the costs, expenses or liabilities likely to be incurred by it in the
making of such investigation is, in the opinion of the Trustee, not reasonably
assured to the Trustee by the security afforded to it by the terms of this
Indenture, the Trustee may require reasonable indemnity against such costs,
expenses or liabilities as a condition to proceeding; the reasonable expenses of
every such examination shall be paid by the Company or, if paid by the Trustee
or any predecessor trustee, shall be repaid by the Company upon demand; and

     (g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys not regularly in its employ and the Trustee shall not be responsible
for any misconduct or negligence on the part of any such agent or attorney
appointed with due care by it hereunder.

     SECTION 5.3 Trustee Not Responsible for Recitals, Disposition of Securities
or Application of Proceeds Thereof. The recitals contained herein and in the
Securities, except the Trustee's certificates of authentication, shall be taken
as the statements of the Company, and the Trustee assumes no responsibility for
the correctness of the same. The Trustee makes no representation as to the
validity or sufficiency of this Indenture or of the Securities. The Trustee
shall not be accountable for the use or application by the Company of any of the
Securities or of the proceeds thereof.

     SECTION 5.4 Trustee and Agents May Hold Securities, Collections, etc. The
Trustee or any agent of the Company or the Trustee, in its individual or any
other capacity, may become the owner or pledgee of Securities with the same
rights it would have if it were not the Trustee or such agent and may otherwise
deal with the Company and receive, collect, hold and retain collections from the
Company with the same rights it would have if it were not the Trustee or such
agent.

     SECTION 5.5 Moneys Held By Trustee. Subject to the provisions of Section
9.6, all moneys received by the Trustee shall, until used or applied as herein
provided, be held in trust for the purposes for which they were received, but
need not be segregated from other funds except to the extent required by
mandatory provisions of law. Neither the Trustee
<PAGE>
 
                                                                              50


nor any agent of the Company or the Trustee shall be under any liability for
interest on any moneys received by it hereunder.

     SECTION 5.6 Compensation and Indemnification of Trustee and Its Prior
Claim. The Company covenants and agrees to pay to the Trustee from time to time,
and the Trustee shall be entitled to, reasonable compensation as agreed to by
the Company and the Trustee (which shall not be limited by any provision of law
in regard to the compensation of a trustee of an express trust), and the Company
covenants and agrees to pay or reimburse the Trustee and each predecessor
trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by or on behalf of it in accordance with any of the provisions
of this Indenture (including the reasonable compensation and the expenses and
disbursements of its counsel and of all agents and other persons not regularly
in its employ) except any such expense, disbursement or advance as may arise
from its negligence or bad faith. The Company also covenants to indemnify the
Trustee and each predecessor trustee for, and to hold it harmless against, any
loss, liability or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of this
Indenture or the trusts hereunder and its duties hereunder, including the costs
and expenses of enforcing this Indenture against the Company (including this
Section 5.6) and of defending itself against or investigating any claim (whether
asserted by a Holder or the Company) of liability in the premises. The
obligations of the Company under this Section to compensate and indemnify the
Trustee and each predecessor trustee and to pay or reimburse the Trustee and
each predecessor trustee for expenses, disbursements and advances shall
constitute additional indebtedness hereunder and shall survive the satisfaction
and discharge of this Indenture. Such additional indebtedness shall be a senior
claim to that of the Securities upon all property and funds held or collected by
the Trustee as such, except funds held in trust for the benefit of the holders
of particular Securities, and the Securities are hereby subordinated to such
senior claim.

     SECTION 5.7 Right of Trustee to Rely on Officer's Certificate, Etc. Subject
to Sections 5.1 and 5.2, whenever in the administration of the trusts of this
Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or bad faith on the
part of the Trustee, be deemed to be conclusively proved and established by an
Officer's Certificate delivered to the Trustee, and such certificate, in the
absence of negligence or bad faith on the part of the Trustee, shall be full
warrant to the Trustee for any action taken, suffered or omitted by it under the
provisions of this Indenture upon the faith thereof.

     SECTION 5.8 Persons Eligible for Appointment as Trustee. The Trustee
hereunder shall at all times be a corporation having a combined capital and
surplus of at least $50,000,000, and which is eligible in accordance with the
provisions of Section 310(a) of the Trust Indenture Act. If such corporation
publishes reports of condition at least annually, pursuant to law or to the
requirements of a Federal, State or District of Columbia supervising or
examining authority, then for the purposes of this Section, the combined capital
and
<PAGE>
 
                                                                              51


surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.

     SECTION 5.9 Resignation and Removal; Appointment of Successor Trustee. (a)
The Trustee may at any time resign by giving written notice of resignation to
the Company and by mailing notice thereof by first-class mail to holders of
Securities at their last addresses as they shall appear on the Security
register. Upon receiving such notice of resignation, the Company shall promptly
appoint a successor trustee by written instrument in duplicate, executed by
authority of the Board of Directors, one copy of which instrument shall be
delivered to the resigning Trustee and one copy to the successor trustee. If no
successor trustee shall have been so appointed and have accepted appointment
within 30 days after the mailing of such notice of resignation, the resigning
trustee may petition any court of competent jurisdiction for the appointment of
a successor trustee, or any Securityholder who has been a bona fide holder of a
Security or Securities for at least six months may, on behalf of himself and all
others similarly situated, petition any such court for the appointment of a
successor trustee. Such court may thereupon, after such notice, if any, as it
may deem proper, prescribe and appoint a successor trustee.

     (b) In case at any time any of the following shall occur:

          (i) the Trustee shall fail to comply with the provisions of Section
     310(b) of the Trust Indenture Act, after written request therefor by the
     Company or by any Securityholder who has been a bona fide holder of a
     Security or Securities for at least six months; or

          (ii) the Trustee shall cease to be eligible in accordance with the
     provisions of Section 5.8 and shall fail to resign after written request
     therefor by the Company or by any such Securityholder; or

          (iii) the Trustee shall become incapable of acting, or shall be
     adjudged a bankrupt or insolvent, or a receiver or liquidator of the
     Trustee or of its property shall be appointed, or any public officer shall
     take charge or control of the Trustee or of its property or affairs for the
     purpose of rehabilitation, conservation or liquidation;

then, in any such case, the Company may remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed by order of the
Board of Directors of the Company, one copy of which instrument shall be
delivered to the Trustee so removed and one copy to the successor trustee, or,
subject to Section 315(e) of the Trust Indenture Act, any Securityholder who has
been a bona fide holder of a Security or Securities for at least six months may
on behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor trustee. Such court may thereupon, after such notice, if any, as it
may deem proper and prescribe, remove the Trustee and appoint a successor
trustee.

     (c) The holders of a majority in aggregate principal amount of the
Securities at the time outstanding may at any time remove the Trustee and
appoint a successor trustee by
<PAGE>
 
                                                                              52

delivering to the Trustee so removed, to the successor trustee so appointed and
to the Company the evidence provided for in Section 6.1 of the action in that
regard taken by the Securityholder.

     (d) Any resignation or removal of the Trustee and any appointment of a
successor trustee pursuant to any of the provisions of this Section 5.9 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 5.l0.

     SECTION 5.10 Acceptance of Appointment by Successor Trustee. Any successor
trustee appointed as provided in Section 5.9 shall execute and deliver to the
Company and to its predecessor trustee an instrument accepting such appointment
hereunder, and thereupon the resignation or removal of the predecessor trustee
shall become effective and such successor trustee, without any further act, deed
or conveyance, shall become vested with all rights, powers, duties and
obligations of its predecessor hereunder, with like effect as if originally
named as trustee herein; but, nevertheless, on the written request of the
Company or of the successor trustee, upon payment of its charges then unpaid,
the trustee ceasing to act shall, subject to Section 9.6, pay over to the
successor trustee all moneys at the time held by it hereunder and shall execute
and deliver an instrument transferring to such successor trustee all such
rights, powers, duties and obligations. Upon request of any such successor
trustee, the Company shall execute any and all instruments in writing for more
fully and certainly vesting in and confirming to such successor trustee all such
rights and powers. Any trustee ceasing to act shall, nevertheless, retain a
prior claim upon all property or funds held or collected by such trustee to
secure any amounts then due it pursuant to the provisions of Section 5.6.

     Upon acceptance of appointment by a successor trustee as provided in this
Section 5.10, the Company shall mail notice thereof by first-class mail to the
holders of Securities at their last addresses as they shall appear in the
Security register. If the acceptance of appointment is substantially
contemporaneous with the resignation, then the notice called for by the
preceding sentence may be combined with the notice called for by Section 5.9. If
the Company fails to mail such notice within 10 days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Company.

     SECTION 5.11 Merger, Conversion, Consolidation or Succession to Business of
Trustee. Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to the corporate trust business of the Trustee, shall be
the successor of the Trustee hereunder, provided that such corporation shall be
eligible under the provisions of Section 5.8, without the execution or filing of
any paper or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding.

     In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture any of the Securities shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the
certificate of authentication of any
<PAGE>
 
                                                                              53


predecessor trustee and deliver such Securities so authenticated; and, in case
at that time any of the Securities shall not have been authenticated, any
successor to the Trustee may authenticate such Securities either in the name of
any predecessor hereunder or in the name of the successor trustee; and in all
such cases such certificate shall have the full force which it is anywhere in
the Securities or in this Indenture; provided that the certificate of the
Trustee shall have provided that the right to adopt the certificate of
authentication of any predecessor trustee or to authenticate Securities in the
name of any predecessor trustee shall apply only to its successor or successors
by merger, conversion or consolidation.

     SECTION 5.12 Notice of Defaults. If a Default or Event of Default occurs
and is continuing and if a Trust Officer has actual knowledge thereof, the
Trustee shall mail to each Holder notice of the Default or Event of Default
within 90 days after it occurs. Except in the case of a Default or Event of
Default in payment of principal of, or interest on, any Security (including
payments pursuant to the optional redemption or required repurchase provisions
of such Security, if any), the Trustee may withhold the notice if and so long as
its board of directors, the Executive Committee of its board of directors or a
committee of its Trust Officers in good faith determines that withholding the
notice is in the interests of Securityholders.

     SECTION 5.13 Reports by the Trustee. The Trustee shall transmit to the
Holders all reports required under Section 313(a) of the Trust Indenture Act.

                                   ARTICLE VI

                         CONCERNING THE SECURITYHOLDERS

     SECTION 6.1 Evidence of Action Taken by Securityholders. Any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Securityholders may be
embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Securityholders in person or by agent duly appointed in
writing; and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the
Trustee. Proof of execution of any instrument or of a writing appointing any
such agent shall be sufficient for any purpose of this Indenture and (subject to
Sections 5.1 and 5.2) conclusive in favor of the Trustee and the Company, if
made in the manner provided in this Article.

     SECTION 6.2 Proof of Execution of Instruments and of Holding of Securities;
Record Date. Subject to Sections 5.1 and 5.2, the execution of any instrument by
a Securityholder or his agent or proxy may be proved in accordance with such
reasonable rules and regulations as may be prescribed by the Trustee or in such
manner as shall be satisfactory to the Trustee. The holding of Securities shall
be proved by the Security register or by a certificate of the registrar thereof.
The Company may set a record date for purposes of determining the identity of
holders of Securities entitled to vote or consent to any action referred to in
Section 6.1, which record date may be set at any time or from time to time by
<PAGE>
 
                                                                              54


notice to the Trustee, for any date or dates (in the case of any adjournment or
resolicitation) not more than 60 days nor less than five days prior to the
proposed date of such vote or consent, and thereafter, notwithstanding any other
provisions hereof, only holders of Securities of record on such record date
shall be entitled to so vote or give such consent or to withdraw such vote or
consent.

     SECTION 6.3 Holders to be Treated as Owners. The Company, the Trustee and
any agents of the Company or the Trustee may deem and treat the person in whose
name any Security shall be registered upon the Security register as the absolute
owner of such Security (whether or not such Security shall be overdue and
notwithstanding any notation of ownership or other writing thereon) for the
purpose of receiving payment of or on account of the principal of and, subject
to the provisions of this Indenture, interest on such Security and for all other
purposes; and neither the Company nor the Trustee nor any agent of the Company
or the Trustee shall be affected by any notice to the contrary; provided,
however, that the Depository, or its nominee, shall be deemed the owner of the
Restricted Global Security, and owners of beneficial interests in the Restricted
Global Security will not be considered the owners of any Securities. All such
payments so made to any such person, or upon his order, shall be valid, and, to
the extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for moneys payable upon any such Security.

     SECTION 6.4 Securities Owned by Company Deemed Not Outstanding. In
determining whether the holders of the requisite aggregate principal amount of
Securities have concurred in any direction, consent or waiver under this
Indenture, Securities which are owned by the Company or any other obligor on the
Securities or by any person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Company or any other obligor
on the Securities shall be disregarded and deemed not to be outstanding for the
purpose of any such determination, except that for the purpose of determining
whether the Trustee shall be protected in relying on any such direction, consent
or waiver only Securities which the Trustee knows are so owned shall be so
disregarded. Securities so owned which have been pledged in good faith may be
regarded as outstanding if the pledgee establishes to the satisfaction of the
Trustee the pledgee's right so to act with respect to such Securities and that
the pledgee is not the Company or any other obligor upon the Securities or any
person directly or indirectly controlling or controlled by or under direct or
indirect common control with the Company or any other obligor on the Securities.
In case of a dispute as to such right, the advice of counsel shall be full
protection in respect of any decision made by the Trustee in accordance with
such advice. Upon request of the Trustee, the Company shall furnish to the
Trustee promptly an Officer's Certificate listing and identifying all
Securities, if any, known by the Company to be owned or held by or for the
account of any of the above-described persons; and, subject to Sections 5.1 and
5.2, the Trustee shall be entitled to accept such Officer's Certificate as
conclusive evidence of the facts therein set forth and of the fact that all
Securities not listed therein are outstanding for the purpose of any such
determination.

     SECTION 6.5 Right of Revocation of Action Taken. At any time prior to (but
not after) the evidencing to the Trustee, as provided in Section 6.1, of the
taking of any action by the holders of the percentage in aggregate principal
amount of the Securities
<PAGE>
 
                                                                              55


specified in this Indenture in connection with such action, any holder of a
Security the serial number of which is shown by the evidence to be included
among the serial numbers of the Securities the holders of which have consented
to such action may, by filing written notice at the Corporate Trust Office and
upon proof of holding as provided in this Article, revoke such action so far as
concerns such Security. Except as aforesaid, any such action taken by the holder
of any Security shall be conclusive and binding upon such holder and upon all
future holders and owners of such Security and of any Securities issued in
exchange or substitution therefor, irrespective of whether or not any notation
in regard thereto is made upon any such Security. Any action taken by the
holders of the percentage in aggregate principal amount of the Securities
specified in this Indenture in connection with such action shall be conclusively
binding upon the Company, the Trustee and the holders of all the Securities.

                                   ARTICLE VII

                                   AMENDMENTS

     SECTION 7.1 Without Consent of Holders. The Company and the Trustee may
amend this Indenture or the Securities without notice to or consent of any
Holder:

     (a) to cure any ambiguity, omission, defect or inconsistency;

     (b) to comply with Article VIII;

     (c) to provide for uncertificated Securities in addition to or in place of
certificated Securities; provided, however, that the uncertificated Securities
are issued in registered form for purposes of Section 163(f) of the Code or in a
manner such that the uncertificated Securities are described in Section
163(f)(2)(B) of the Code;

     (d) to make any change in Article X that would limit or terminate the
benefits available to any holder of Senior Indebtedness (or Representatives
therefor) under Article X;

     (e) to add Guarantees with respect to the Securities or to secure the
Securities;

     (f) to add to the covenants of the Company for the benefit of the Holders
or to surrender any right or power herein conferred upon the Company;

     (g) to comply with any requirements of the Commission in connection with
qualifying this Indenture under the Trust Indenture Act;

     (h) to make any change that does not adversely affect the rights of any
Holder; or

     (i) to provide for the issuance of the Conversion Notes, which will have
terms substantially identical in all material respects to the Initial Notes
(except that the transfer restrictions contained in the Initial Notes will be
modified or eliminated, as appropriate), and
<PAGE>
 
                                                                              56


which will be treated, together with any outstanding Initial Notes, as a single
issue of securities.

     An amendment under this Section 7.1 may not make any change that adversely
affects the rights under Article X of any holder of Senior Indebtedness then
outstanding unless the holders of such Senior Indebtedness (or any group or
representative thereof authorized to give a consent) consent to such change.

     After an amendment under this Section 7.1 becomes effective, the Company
shall mail to each Holder a notice briefly describing such amendment. The
failure to give such notice to all Holders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section 7.1.

     SECTION 7.2 With Consent of Holders. The Company and the Trustee may amend
this Indenture or the Securities without notice to any Holder but with the
written consent of the Holders of at least a majority in principal amount of the
Securities. However, without the consent of each Holder affected, an amendment
may not:

     (a) reduce the amount of Securities whose Holders must consent to an
amendment;

     (b) reduce the rate of or extend the time for payment of interest on any
     Security;

     (c) reduce the principal of or extend the Stated Maturity of any Security

     (d) reduce the premium payable upon the redemption or repurchase of any
Security or change the time at which any Security may or shall be redeemed or
repurchased in accordance with this Indenture;

     (e) make any Security payable in money other than that stated in the
Security;

     (f) modify or affect in any manner adverse to the Holders, the terms and
conditions of the obligation of the Company for the due and punctual payment of
the principal of or interest on Securities; or

     (g) make any change in Section 4.4 or 4.7 or the second sentence of this
Section 7.2.

     It shall not be necessary for the consent of the Holders under this Section
to approve the particular form of any proposed amendment, but it shall be
sufficient if such consent approves the substance thereof.

     An amendment under this Section 7.2 may not make any change that adversely
affects the rights under Article X of any holder of Senior Indebtedness then
outstanding
<PAGE>
 
                                                                              57


unless the holders of such Senior Indebtedness (or any group or representative
thereof authorized to give a consent) consent to such change.

     After an amendment under this Section 7.2 becomes effective, the Company
shall mail to Holders a notice briefly describing such amendment. The failure to
give such notice to all Holders, or any defect therein, shall not impair or
affect the validity of an amendment under this Section 7.2.

     SECTION 7.3 Compliance with Trust Indenture Act. Every amendment to this
Indenture or the Securities shall comply with the Trust Indenture Act as then in
effect.

     SECTION 7.4 Revocation and Effect of Consents and Waivers. A consent to an
amendment or a waiver by a Holder of a Security shall bind the Holder and every
subsequent Holder of that Security or portion of the Security that evidences the
same debt as the consenting Holder's Security, even if notation of the consent
or waiver is not made on the Security. However, any such Holder or subsequent
Holder may revoke the consent or waiver as to such Holder's Security or portion
of Security if the Trustee receives the notice of revocation before the date the
amendment or waiver becomes effective. After an amendment or waiver becomes
effective, it shall bind every Holder.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders entitled to give their consent or take any
other action described above or required or permitted to be taken pursuant to
this Indenture. If a record date is fixed, then notwithstanding the immediately
preceding paragraph, those Persons who were Holders at such record date (or
their duly designated proxies), and only those Persons, shall be entitled to
give such consent or to revoke any consent previously given or to take any such
action, whether or not such Persons continue to be Holders after such record
date. No such consent shall become valid or effective more than 120 days after
such record date.

     SECTION 7.5 Notation on or Exchange of Securities. If an amendment changes
the terms of a Security, the Trustee may require the Holder of the Security to
deliver it to the Trustee. The Trustee may place an appropriate notation on the
Security regarding the changed terms and return it to the Holder. Alternatively,
if the Company or the Trustee so determines, the Company in exchange for the
Security shall issue and the Trustee shall authenticate a new Security that
reflects the changed terms. Failure to make the appropriate notation or to issue
a new Security shall not affect the validity of such amendment.

     SECTION 7.6 Trustee to Sign Amendments. The Trustee shall sign any
amendment authorized pursuant to this Article VII if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it. In signing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Section 7.1) shall be fully protected in relying
upon, an Officer's Certificate and an Opinion of Counsel stating that such
amendment is authorized or permitted by this Indenture.

                                  ARTICLE VIII

                            MERGER AND CONSOLIDATION

     SECTION 8.1 When Company May Merge, Etc. The Company shall not consolidate
with or merge with or into, or convey, transfer or lease all or substantially
all its assets to, any Person, unless: (i) the resulting, surviving or
transferee Person (the "Successor Company") shall be a Person organized and
existing under the laws of the United States of America, any state thereof or
the District of Columbia and the Successor Company (if not the Company) shall
expressly assume, by an indenture supplemental to this Indenture, executed and
delivered to the Trustee, in form reasonably satisfactory to the Trustee, all
the obligations of the Company under the Securities and this Indenture; (ii)
immediately after giving effect to such transaction (and treating any
Indebtedness which becomes an obligation of the Successor Company or any
Restricted Subsidiary as a result of such transaction as having been incurred by
such Successor Company or such Restricted Subsidiary at the time of such
transaction), no Event of Default shall have occurred and be continuing; (iii)
immediately after giving pro forma effect to such transaction, as if such
transaction had occurred at the beginning of the applicable four-quarter period,
the Successor Company would be permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Consolidated Coverage Ratio test set forth in
Section 3.8(a); and (iv) the Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that such
consolidation, merger or transfer and such supplemental indenture (if any)
comply with this Indenture.

     SECTION 8.2 Successor Corporation Substituted. The Successor Company shall
be the successor of the Company and shall succeed to, and be substituted for,
and may exercise every right and power of, the Company under this Indenture, but
the predecessor Company in the case of a conveyance, transfer or lease shall not
be released from the obligation to pay the principal of and interest on the
Securities.

     Such Successor Company may cause to be signed, and may issue either in its
own name or in the name of the Company prior to such succession any or all of
the Securities issuable hereunder which theretofore shall not have been signed
by the Company and delivered to the Trustee; and, upon the order of such
successor corporation, instead of the Company, and subject to all the terms,
conditions and limitations in this Indenture prescribed, the Trustee shall
authenticate and shall deliver any Securities which previously shall have been
signed and delivered by the officers of the Company to the Trustee for
authentication, and any Securities which such successor corporation thereafter
shall cause to be signed and delivered to the Trustee for that purpose. All of
the Securities so issued shall in all respects have the same legal rank and
benefit under this Indenture as the Securities theretofore or thereafter issued
in accordance with the terms of this Indenture as though all of such Securities
had been issued at the date of the execution hereof.

     In case of any such consolidation, merger, sale, lease or conveyance such
changes in phraseology and form (but not in substance) may be made in the
Securities thereafter to be issued as may be appropriate.

                                                                              59


     In the event of any such sale or conveyance (other than a conveyance by way
of lease) the Company or any Successor Company which shall theretofore have
become such in the manner described in this Article shall be discharged from all
obligations and covenants under this Indenture and the Securities and may be
liquidated and dissolved.

                                   ARTICLE IX

                       DISCHARGE OF INDENTURE; DEFEASANCE

     SECTION 9.1 Discharge of Liability on Securities; Defeasance. (a) When (i)
the Company delivers to the Trustee all outstanding Securities (other than
Securities replaced pursuant to Section 2.6) for cancellation or (ii) all
outstanding Securities have become due and payable, whether at maturity or as a
result of the mailing of a notice of redemption pursuant to Article XIII and the
Company irrevocably deposits with the Trustee funds sufficient to pay at
maturity or upon redemption all outstanding Securities (other than Securities
replaced pursuant to Section 2.6), including interest thereon to maturity or
such redemption date, and if in either case the Company pays all other sums
payable hereunder by the Company, then this Indenture shall, subject to Section
9.1(c), cease to be of further effect. The Trustee shall acknowledge
satisfaction and discharge of this Indenture on demand of the Company
(accompanied by an Officers' Certificate and an Opinion of Counsel stating that
all conditions precedent specified herein relating to the satisfaction and
discharge of this Indenture have been complied with) and at the cost and expense
of the Company.

     (b) Subject to Sections 9.1(c) and 9.2, the Company at any time may
terminate (i) all its obligations under the Securities and this Indenture and
all obligations of the Subsidiary Guarantors under the Subsidiary Guarantee and
this Indenture ("legal defeasance option") or (ii) its obligations under
Sections 3.5, 3.7 through 3.18, 8.1(iii) and 8.1(iv) and the operation of
Sections 4.1(d), 4.1(e), 4.1(f), 4.1(g) (but only with respect to a Material
Subsidiary), 4.1(h) (but only with respect to a Material Subsidiary) and 4.1(i)
("covenant defeasance option"); provided, however, no deposit under this Article
IX shall be effective to terminate the obligations of the Company under the
Securities or this Indenture prior to 123 days following any such deposit. The
Company may exercise its legal defeasance option notwithstanding its prior
exercise of its covenant defeasance option.

     If the Company exercises its legal defeasance option, payment of the
Securities may not be accelerated because of an Event of Default. If the Company
exercises its covenant defeasance option, payment of the Securities may not be
accelerated because of an Event of Default specified in Sections 4.1(d), (e),
(f), (g) (but only with respect to a Material Subsidiary), 4.1(h) (but only with
respect to a Material Subsidiary) and 4.1(i) or because of the failure of the
Company to comply with Section 8.1(iii) and Section 8.1 (iv).

     Upon satisfaction of the conditions set forth herein and upon request of
the Company, the Trustee shall acknowledge in writing the discharge of those
obligations that the Company terminates.

                                                                              60


     (c) Notwithstanding the provisions of Sections 9.1(a) and (b), the
Company's obligations in Article II, Sections 5.6, 5.9, 9.4, 9.5 and 9.6 shall
survive until the Securities have been paid in full. Thereafter, the Company's
obligations in Sections 5.6, 9.4 and 9.5 shall survive.

     SECTION 9.2 Conditions to Defeasance. The Company may exercise its legal
defeasance option or its covenant defeasance option only if:

     (a) the Company irrevocably deposits in trust with the Trustee money or
U.S. Government Obligations for the payment of principal of and interest on the
Securities to maturity or redemption, as the case may be;

     (b) the Company delivers to the Trustee a certificate from a nationally
recognized firm of independent accountants expressing their opinion that the
payments of principal and interest when due and without reinvestment of the
deposited U.S. Government Obligations plus any deposited money without
investment will provide cash at such times and in such amounts as will be
sufficient to pay principal and interest when due on all the Securities to
maturity or redemption, as the case may be;

     (c) no Event of Default shall have occurred or be continuing on the date of
such deposit and 123 days pass after the deposit is made and during the 123-day
period no Default specified in Section 4.1(g) or 4.1(h) with respect to the
Company occurs which is continuing at the end of such period;

     (d) the deposit does not constitute a default under any other agreement
binding on the Company and is not prohibited by Article X;

     (e) the Company delivers to the Trustee an Opinion of Counsel to the effect
that the trust resulting from the deposit does not constitute, or is qualified
as, a regulated investment company under the Investment Company Act of 1940;

     (f) in the case of the legal defeasance option, the Company shall have
delivered to the Trustee an Opinion of Counsel stating that (A) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling, or (B) since the date hereof there has been a change in the applicable
Federal income tax law, in either case to the effect that, and based thereon
such Opinion of Counsel shall confirm that, the Holders will not recognize
income, gain or loss for Federal income tax purposes as a result of such
defeasance and will be subject to Federal income tax purposes on the same
amounts, in the same manner and at the same times as would have been the case if
such legal defeasance had not occurred;

     (g) in the case of the covenant defeasance option, the Company shall have
delivered to the Trustee an Opinion of Counsel to the effect that the Holders
will not recognize income, gain or loss for Federal income tax purposes as a
result of such covenant defeasance and will be subject to Federal income tax on
the same amounts, in the same

                                                                              61


manner and at the same times as would have been the case if such covenant
defeasance had not occurred;

     (h) The Holders shall have a perfected security interest under applicable
law in the cash or U.S. Government Obligations deposited pursuant to Section
9.2(a);

     (i) The Company shall have delivered to the Trustee an Opinion of Counsel,
in form and substance reasonably satisfactory to the Trustee, to the effect
that, after the passage of 123 days following the deposit, the trust funds will
not be subject to any applicable bankruptcy, insolvency, reorganization or
similar law affecting creditors' rights generally;

     (j) such defeasance shall not cause the Trustee to have a conflicting
interest with respect to any securities of the Company; and

     (k) the Company delivers to the Trustee an Officers' Certificate and an
Opinion of Counsel, each stating that all conditions precedent to the defeasance
and discharge of the Securities and this Indenture as contemplated by this
Article IX have been complied with.

     Before or after a deposit, the Company may make arrangements satisfactory
to the Trustee for the redemption of Securities at a future date in accordance
with Article III.

     SECTION 9.3 Application of Trust Money. The Trustee shall hold in trust
money or U.S. Government Obligations deposited with it pursuant to this Article
IX. It shall apply the deposited money and the money from U.S. Government
Obligations through the paying agent and in accordance with this Indenture to
the payment of principal of and interest on the Securities. Money and securities
so held in trust are not subject to Article X.

     SECTION 9.4 Repayment to Company. The Trustee and the paying agent shall
promptly turn over to the Company upon request any excess money or securities
held by them upon payment of all the obligations under this Indenture.

     Subject to any applicable abandoned property law, the Trustee and the
paying agent shall pay to the Company upon request any money held by them for
the payment of principal of or interest on the Securities that remains unclaimed
for two years, and, thereafter, Holders entitled to the money must look to the
Company for payment as general creditors.

     SECTION 9.5 Indemnity for U.S. Government Obligations. The Company shall
pay and shall indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against deposited U.S. Government Obligations or the principal
and interest received on such U.S. Government Obligations.

     SECTION 9.6 Reinstatement. If the Trustee or paying agent is unable to
apply any money or U.S. Government Obligations in accordance with this Article
IX by reason of any legal proceeding or by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, the
<PAGE>
 
                                                                              62


obligations of the Company and the Subsidiary Guarantors under this Indenture
and the Securities shall be revived and reinstated as though no deposit had
occurred pursuant to this Article IX until such time as the Trustee or paying
agent is permitted to apply all such money or U.S. Government Obligations in
accordance with this Article IX; provided, however, that, if the Company has
made any payment of interest on or principal of any Securities because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money or U.S.
Government Obligations held by the Trustee or paying agent.

                                    ARTICLE X

                                 SUBORDINATION.

     SECTION 10.1 Agreement to Subordinate. The Company agrees, and each
Securityholder by accepting a Security agrees, that the payment of the principal
of and interest on the Securities, the payment of all other obligations relating
to the Securities (including prepayment premiums, liquidated damages, fees,
costs, expenses, indemnities and rescission or damage claims) and the payment of
any obligation in respect of any Guarantee of obligations relating to the
Securities (all of the foregoing being collectively referred to as the "Note
Obligations") are subordinate in right of payment, to the extent and in the
manner provided in this Article X, to the prior payment in full of all Senior
Indebtedness and that the subordination is for the benefit of and enforceable by
the holders of Senior Indebtedness. The Securities shall in all respects rank
pari passu with all other Senior Subordinated Indebtedness of the Company, and
only Indebtedness of the Company that is Senior Indebtedness shall rank senior
to the Securities in accordance with the provisions set forth herein. All
provisions of this Article X shall be subject to Section 10.12. For purposes of
this Article X, "payment in full" means payment in cash.

     SECTION 10.2 Liquidation, Dissolution, Bankruptcy. Upon any payment,
distribution or other transfer of the assets of the Company or any Guarantor (or
any other payment, distribution or other transfer on behalf of the Company or
any Guarantor from any source) of any kind or character, whether direct or
indirect, by set-off or otherwise, or whether in cash, property or securities
(other than Reorganization Securities) upon any dissolution, winding up, total
or partial liquidation or reorganization of the Company or any Guarantor
(whether voluntary or involuntary, including in bankruptcy, insolvency or
receivership proceedings or upon any assignment for the benefit of creditors or
any other marshalling of the Company's or any Guarantor's assets and
liabilities):

          (a) holders of Senior Indebtedness shall be entitled to receive
     payment in full of all Senior Indebtedness before Securityholders shall be
     entitled to receive any payment or any distribution of cash, securities or
     other property with respect to the Note Obligations (other than
     Reorganization Securities); and

          (b) until the Senior Indebtedness is paid in full, any payment,
     distribution or other transfer of assets of the Company or any Guarantor of
     any kind or character,
<PAGE>
 
                                                                              63


     whether direct or indirect, by set-off or otherwise, and whether in cash,
     securities or property (other than Reorganization Securities), to which
     Securityholders would be entitled but for this Article X shall be made to
     holders of Senior Indebtedness as their interests may appear.

     SECTION 10.3 Default on Senior Indebtedness. The Company may not, and will
not permit any Guarantor to, make any payment, distribution or other transfer of
the assets of the Company or such Guarantor (or any other payment, distribution
or other transfer on behalf of the Company or any Guarantor from any source) of
any kind, or character, whether direct or indirect, by set-off or otherwise, and
whether in cash, property or securities (other than Reorganization Securities)
in respect of the Note Obligations, or make any deposit pursuant to Section 9.1
and may not, directly or indirectly, repurchase, redeem or otherwise retire any
Securities, whether pursuant to the terms of the Securities or upon acceleration
or otherwise (collectively, "pay the Securities") if (i) all or any portion of
the principal (including any reimbursement obligation) of, premium, if any, or
interest, commitment fee or letter of credit fee on or relating to, any
Designated Senior Indebtedness is not paid when due or (ii) any other default on
Designated Senior Indebtedness occurs and the maturity of such Designated Senior
Indebtedness is accelerated in accordance with its terms unless, in either case,
(x) the default has been cured or waived and any such acceleration has been
rescinded or (y) such Designated Senior Indebtedness has been paid in full;
provided, however, that the Company may pay the Securities without regard to the
foregoing if the Company and the Trustee receive written notice approving such
payment from the Representatives of all Designated Senior Indebtedness with
respect to which either of the events set forth in clause (i) or (ii) of the
immediately preceding sentence has occurred and is continuing. During the
continuance of any default (other than a default described in clause (i) or (ii)
of the preceding sentence) with respect to any Designated Senior Indebtedness
pursuant to which the maturity thereof may be accelerated immediately without
further notice (except such notice as may be required to effect such
acceleration) or the expiration of any applicable grace periods, neither the
Company nor any other Person may pay the Securities for a period (a "Payment
Blockage Period") commencing upon the receipt by the Trustee (with a copy to the
Company) of written notice (a "Blockage Notice") of such default from the
Representative of any Designated Senior Indebtedness specifying an election to
effect a Payment Blockage Period and ending 179 days thereafter (or earlier if
such Payment Blockage Period is terminated (i) by written notice to the Trustee
and the Company from the Person or Persons who gave such Blockage Notice, (ii)
because the default giving rise to such Blockage Notice is no longer continuing,
or (iii) by repayment in full of such Designated Senior Indebtedness); provided'
however, that so long as there shall remain outstanding any Senior Indebtedness
under the Senior Credit Agreement, a Blockage Notice may be given only by the
Credit Agent unless otherwise agreed to in writing by the lenders named therein.
Notwithstanding the provisions described in the immediately preceding sentence
(but subject to the provisions contained in the first sentence of this section),
the Company may resume payments on the Securities after such Payment Blockage
Period. Not more than one Blockage Notice may be given in any consecutive
360-day period, irrespective of the number of defaults with respect to
Designated Senior Indebtedness during such period.

     SECTION 10.4 Acceleration of Payment of Securities. If payment of the
Securities is accelerated because of an Event of Default, the Company or the
Trustee shall promptly notify the holders of the Designated Senior Indebtedness
(or their Representatives) of the acceleration. If any Designated Senior
Indebtedness is outstanding, neither the Company nor any other Person may pay
the Securities until five Business Days after the Representatives of all
Designated Senior Indebtedness receive notice of such acceleration and,
thereafter, may pay the Securities only if such payments are otherwise permitted
pursuant to this Article X at such time.

     SECTION 10.5 When Distribution Must Be Paid Over. If a distribution is made
to Securityholders that, because of this Article X, should not have been made to
them, the Securityholders who receive the distribution shall hold it in trust
for holders of Senior Indebtedness and pay it over to them as their interests
may appear.

     SECTION 10.6 Subrogation. After all Senior Indebtedness is paid in full and
until the Securities are paid in full, Securityholders shall be subrogated to
the rights of holders of Senior Indebtedness to receive distributions applicable
to Senior Indebtedness. A distribution made under this Article X to holders of
Senior Indebtedness which otherwise would have been made to Securityholders is
not, as between the Company and Securityholders, a payment by the Company on
Senior Indebtedness.

     SECTION 10.7 Relative Rights. This Article X defines the relative rights of
Securityholders and holders of Senior Indebtedness. Nothing in this Indenture
shall:

          (1) impair, as between the Company and Securityholders, the obligation
     of the Company, which is absolute and unconditional, to pay principal of
     and interest on the Securities in accordance with their terms; or

          (2) prevent the Trustee or any Securityholder from exercising its
     available remedies upon a Default, subject to the rights hereunder of
     holders of Senior Indebtedness to receive any payment, distribution or
     transfer otherwise payable to Securityholders.

     SECTION 10.8 Subordination May Not Be Impaired By Company. No right of any
holder of Senior Indebtedness to enforce the subordination of the Indebtedness
evidenced by the Securities shall be impaired by any act or failure to act by
the Company or by its failure to comply with this Indenture.

     SECTION 10.9 Rights of Trustee and Paying Agent. Notwithstanding Section
10.3, the Trustee or paying agent may continue to make payments on the
Securities and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payments unless, not less than two
Business Days prior to the date of such payment, a Trust Officer of the Trustee
receives notice that payments may not be made under this Article X. The Company,
the registrar, if any, the paying agent, a Representative or a holder of
Designated Senior Indebtedness may give such notice; provided, however, that, if
an issue
<PAGE>
 
                                                                              65


of Designated Senior Indebtedness has a Representative, only the Representative
may give such notice.

     The Trustee in its individual or any other capacity may hold Senior
Indebtedness with the same rights it would have if it were not Trustee. The
Registrar and co-registrar and the Paying Agent may do the same with like
rights. The Trustee shall be entitled to all the rights set forth in this
Article X with respect to any Senior Indebtedness which may at any time be held
by it, to the same extent as any other holder of Senior Indebtedness; and,
nothing in Article V shall deprive the Trustee of any of its rights as such
holder. Nothing in this Article X shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 5.6.

     SECTION 10.10 Distribution or Notice to Representative. Whenever a
distribution is to be made or a notice given to holders of Senior Indebtedness,
the distribution may be made and the notice given to their Representative (if
any).

     SECTION 10.11 Article X Not To Prevent Events of Default or Limit Right to
Accelerate. The failure to make a payment pursuant to the Securities by reason
of any provision in this Article X shall not be construed as preventing the
occurrence of a Default. Nothing in this Article X shall have any effect on the
right of the Securityholders or the Trustee to accelerate the maturity of the
Securities.

     SECTION 10.12 Trust Moneys Not Subordinated. Notwithstanding anything
contained herein to the contrary, payments from money or the proceeds of U.S.
Government Obligations held in trust in accordance with Article IX by the
Trustee for the payment of principal of and interest on the Securities shall not
be subordinated to the prior payment of any Senior Indebtedness or subject to
the restrictions set forth in this Article X, and none of the Securityholders
shall be obligated to pay over any such amount to the Company or any holder of
Senior Indebtedness of the Company or any other creditor of the Company.

     SECTION 10.13 Trustee Entitled to Rely. Upon any payment or distribution
pursuant to this Article X, the Trustee and the Securityholders shall be
entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 10.2
are pending, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Trustee or to the
Securityholders or (iii) upon the Representatives for the holders of Senior
Indebtedness for the purpose of ascertaining the Persons entitled to participate
in such payment or distribution, the holders of the Senior Indebtedness and
other Indebtedness of the Company or any Guarantor, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article X. In the event that the Trustee
determines, in good faith, that evidence is required with respect to the right
of any Person as a holder of Senior Indebtedness to participate in any payment
or distribution pursuant to this Article X, the Trustee may request such Person
to furnish evidence to the reasonable satisfaction of the Trustee as to the
amount of Senior Indebtedness held by such Person, the extent to which such
Person is entitled to participate in such payment or distribution and other
facts pertinent to the rights of such Person under this Article X, and, if such
evidence is not furnished, the
<PAGE>
 
                                                                              66


Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment. The provisions of Sections
5.1 and 5.2 shall be applicable to all actions or omissions of actions by the
Trustee pursuant to this Article X.

     SECTION 10.14 Trustee to Effectuate Subordination. Each Securityholder by
accepting a Security authorizes and directs the Trustee on his behalf to take
such action as may be necessary or appropriate to acknowledge or effectuate the
subordination between the Securityholders and the holders of Senior Indebtedness
as provided in this Article X and appoints the Trustee as attorney-in-fact for
any and all such purposes.

     SECTION 10.15 Trustee Not Fiduciary for Holders of Senior Indebtedness. The
Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior
Indebtedness and shall not be liable to any such holders if it shall mistakenly,
in the absence of gross negligence or willful misconduct, pay over or distribute
to Securityholders or the Company or any other Person, money or assets to which
any holders of Senior Indebtedness shall be entitled by virtue of this Article X
or otherwise.

     SECTION 10.16 Reliance by Holders of Senior Indebtedness on Subordination
Provisions. Each Securityholder by accepting a Security acknowledges and agrees
that the foregoing subordination provisions are, and are intended to be, an
inducement and a consideration to each holder of any Senior Indebtedness,
whether such Senior Indebtedness was created or acquired before or after the
issuance of the Securities, to acquire and continue to hold, or to continue to
hold, such Senior Indebtedness and such holder of Senior Indebtedness shall be
deemed conclusively to have relied on such subordination provisions in acquiring
and continuing to hold, or in continuing to hold, such Senior Indebtedness.

     SECTION 10.17 Miscellaneous Subordination Provisions. (a) The subordination
provisions contained herein are solely for the benefit of the holders from time
to time of Senior Indebtedness and their representatives, assignees and
beneficiaries and may not be rescinded, cancelled, amended or modified in any
way other than any amendment or modification that would not adversely affect the
rights of any holder of Senior Indebtedness. No holder of Subordinated
Indebtedness shall subordinate any Subordinated Indebtedness to any indebtedness
or obligation of the Company or any Guarantor other than Senior Indebtedness.

     (b) No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or any Guarantor or by any act or failure to act, in good faith, by any such
holder, or by any non-compliance by the Company or any Guarantor with the terms,
provisions and covenants of this Indenture, regardless of any knowledge thereof
any such holder may have or be otherwise charged with.

     (c) Without in any way limiting the generality of Section 10.17(b), the
holders of Senior Indebtedness may, at any time and from time to time, without
the consent of or notice to the holders of the Securities, without incurring
responsibility to the holders of the Securities and without impairing or
releasing the subordination provided in this Article X or
<PAGE>
 
                                                                              67


the obligations hereunder of the holders of the Securities to the holders of
Senior Indebtedness, do any one or more of the following: (i) change the manner,
place or terms of payment or extend the time of payment of, or renew or alter,
Senior Indebtedness or any instrument evidencing the same or any agreement under
which Senior Indebtedness is outstanding; (ii) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (iii) release any Person liable in any manner for the collection
of Senior Indebtedness; and (iv) exercise or refrain from exercising any rights
against the Company and any other Person.

     (d) The subordination provisions of this Article X shall, to the fullest
extent permitted by law, continue to be effective or be reinstated, as the case
may be, if at any time payment and performance of the Senior Indebtedness is,
pursuant to applicable law, avoided, recovered, or rescinded or must otherwise
be restored or returned by any holder of Senior Indebtedness, whether as a
"violable preference," "fraudulent conveyance, "fraudulent transfer," or
otherwise, all as though such payment or performance had not been made.

     (e) If, upon any proceeding referred to in Section 10.2, the Trustee does
not file a claim in such proceeding prior to ten Business Days before the
expiration of the time to file such claim, the holders of the Senior
Indebtedness or their agent may file such claim on behalf of the holders of the
Securities.

                                   ARTICLE XI

                              SUBSIDIARY GUARANTEE

     SECTION 11.1 Subsidiary Guarantee. Each Guarantor hereby unconditionally
and irrevocably guarantees (each a "Subsidiary Guarantee") on a senior
subordinated basis to each Holder and to the Trustee and its successors and
assigns all obligations of the Company under this Indenture and the Securities.
The Guarantor further agrees that the obligations of the Company may be extended
or renewed, in whole or in part, without notice or further assent from such
Guarantor, and that such Guarantor will remain bound under this Article XI
notwithstanding any extension or renewal of any such obligation.

     Each Guarantor waives presentation to, demand of, payment from and protest
to the Company of any of the Company's obligations and also waives notice of
protest for nonpayment. Each Guarantor waives notice of any default under the
Securities or the Company's obligations. The obligations of any Guarantor
hereunder shall not be affected by (a) the failure of any Holder or the Trustee
to assert any claim or demand or to enforce any right or remedy against the
Company or any other Person under this Indenture, the Securities or any other
agreement or otherwise; (b) any extension or renewal of any thereof; (c) any
rescission, waiver, amendment or modification of any of the terms or provisions
of this Indenture, the Securities or any other agreement; (d) the release of any
security held by any Holder or the trustee for the obligations of the Company or
any of them; (e) the failure of any Holder or Trustee to exercise any right or
remedy against any other guarantor of the obligations of the Company; or (fl any
change in the ownership of such Guarantor.
<PAGE>
 
                                                                              68


     Each Guarantor further agrees that its Subsidiary Guarantee constitutes a
guarantee of payment, performance and compliance when due (and not a guarantee
of collection) and waives any right to require that any resort be had by any
Holder or the Trustee to any security held for payment of the obligations of the
Company.

     Each Guarantor's Subsidiary Guarantee is, to the extent and manner set
forth in Article X, subordinated in right of payment to the prior payment in
full of all Senior Indebtedness of such Guarantor and each such Guarantor's
Subsidiary Guarantee is made subject to such provisions of this Indenture. For
purposes of this Section 11.1, "payment in full," as used with respect to Senior
Indebtedness means the receipt of cash.

     The obligations of each Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, including any
claim of waiver, release, surrender, alteration or compromise, and shall not be
subject to any defense of set-off, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or unenforceability of the
obligations or otherwise. Without limiting the generality of the foregoing, the
obligations of each Guarantor herein shall not be discharged or impaired or
otherwise affected by the failure of any Holder or the Trustee to assert any
claim or demand or to enforce any remedy under this Indenture, the Securities or
any other agreement, by any waiver or modification of any thereof, by any
default, failure or delay, willful or otherwise, in the performance of the
obligations, or by any other act or thing or omission or delay to do any other
act or thing which may or might in any manner or to any extent vary the risk of
such Guarantor or would otherwise operate as a discharge of such Guarantor as a
matter of law or equity.

     Each Guarantor further agrees that its Subsidiary Guarantee shall continue
to be effective or be reinstated, as the case may be, if at any time payment, or
any part thereof, of principal of or interest on any obligation is rescinded or
must otherwise be restored by any Holder or the Trustee upon the bankruptcy or
reorganization of the Company or otherwise.

     In furtherance of the foregoing and not in limitation of any other right
that any Holder or the Trustee has at law or in equity against any Guarantor by
virtue hereof, upon the failure of the Company to pay the principal of or
interest on any of the Securities when and as the same shall become due, whether
at maturity, by acceleration, by redemption or otherwise, or to perform or
comply with any other monetary obligation of the Company under this Indenture or
the Securities, each Guarantor hereby promises to and will, upon receipt of
written demand by the Trustee, but subject to Article X forthwith pay, or cause
to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of
(i) the unpaid principal amount of such obligations, (ii) accrued and unpaid
interest on such obligations (but only to the extent not prohibited by law) and
(iii) all other monetary obligations of the Company to the Holders and the
Trustee.

     Each Guarantor agrees that it shall not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed
hereby until payment in full of all such obligations. Each Guarantor further
agrees that, as between it, on the one hand, and the Holders and the Trustee, on
the other hand, (x) the maturity of the obligations
<PAGE>
 
                                                                              69


guaranteed hereby may be accelerated as provided in Article IV for the purposes
of such Guarantor's Subsidiary Guarantee, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (y) in the event of any declaration of acceleration of
such obligations as provided in Article IV, such obligations (whether or not due
and payable) shall forthwith become due and payable by the Guarantor for the
purposes of this Section.

     Each Guarantor also agrees to pay any and all costs and expenses (including
reasonable counsels' fees and expenses) incurred by the Trustee or any Holder in
enforcing any rights under this section with respect to such Guarantor.

     SECTION 11.2 Limitation on Liability. Any term or provision of this
Indenture to the contrary notwithstanding, the maximum, aggregate amount of the
obligations guaranteed hereunder by any Guarantor shall not exceed the maximum
amount that can, after giving effect to all other contingent and fixed
liabilities of such Guarantor be hereby guaranteed without rendering this
Indenture, as it relates to such Guarantor, voidable under applicable law
relating to fraudulent conveyance or fraudulent transfer or similar laws
affecting the rights of creditors generally.

     SECTION 11.3 Successors and Assigns. This Article XI shall be binding upon
each Guarantor and its respective successors and assigns and shall enure to the
benefit of the successors and assigns of the Trustee and the Holders and, in the
event of any transfer or assignment of rights by any Holder or the Trustee, the
rights and privileges conferred upon that party in this Indenture and in the
Securities shall automatically extend to and be vested in such transferee or
assignee, all subject to the terms and conditions of this Indenture.

     SECTION 11.4 No Waiver. Neither a failure nor a delay on the part of either
the Trustee or the Holders in exercising any right, power or privilege under
this Article XI shall operate as a waiver thereof, nor shall a single or partial
exercise thereof preclude any other or further exercise of any right, power or
privilege. The rights, remedies and benefits of the trustee and the Holders
herein expressly specified are cumulative and not exclusive of any other rights,
remedies or benefits which either may have under this Article XI at law, in
equity, by statute or otherwise.

     SECTION 11.5 Modification. No modification, amendment or waiver of any
provision of this Article XI, nor the consent to any departure by any Guarantor
therefrom, shall in any event be effective unless the same shall be in writing
and signed by the Trustee, and then such waiver or consent shall be effective
only in the specific instance and for the purpose for which given. No notice to
or demand on any Guarantor in any case shall entitle such Guarantor to any other
or further notice or demand in the same, similar or other circumstance.

     SECTION 11.6 Release. If at any time shares of the Capital Stock of any
Guarantor shall be sold in a transaction the Net Cash Proceeds of which are
applied in accordance with the provisions of Section 3.12 which results in such
Guarantor no longer constituting a Subsidiary, the Trustee is hereby authorized
and directed to execute and deliver
<PAGE>
 
                                                                              70


a release of such Guarantor from its obligations and liabilities under this
Article XI upon receipt by the Trustee of reasonable evidence of compliance with
the requirements of this Section 11.6.

                                   ARTICLE XII

                            MISCELLANEOUS PROVISIONS

     SECTION 12.1 Incorporators, Officers and Directors of Company Exempt from
Individual Liability. No recourse under or upon any obligation, covenant or
agreement contained in this Indenture, or in any Security, or because of any
indebtedness evidenced thereby, shall be had against any incorporator, as such
or against any past, present or future stockholder, officer or director, as
such, of the Company or of any successor, either directly or through the Company
or any successor, under any rule of law, statute or constitutional provision or
by the enforcement of any assessment or by any legal or equitable proceeding or
otherwise, all such liability being expressly waived and released by the
acceptance of the Securities by the holders thereof and as part of the
consideration for the issue of the Securities.

     SECTION 12.2 Provisions of Indenture for the Sole Benefit of Parties and
Securityholders. Nothing in this Indenture or in the Securities, expressed or
implied, shall give or be construed to give to any person, firm or corporation,
other than the parties hereto and their successors and the holders of the
Securities, any legal or equitable right, remedy or claim under this Indenture
or under any covenant or provision herein contained, all such covenants and
provisions being for the sole benefit of the parties hereto and their successors
and of the holders of the Securities, except that the provisions of Article X
hereof are included herein for the benefit of the holders of Senior
Indebtedness.

     SECTION 12.3 Successors and Assigns of Company Bound by Indenture. All the
covenants, stipulations, promises and agreements in this Indenture contained by
or in behalf of the Company shall bind its successors and assigns, whether so
expressed or not.

     SECTION 12.4 Notices and Demands on Company, Trustee and Securityholders.
Any notice or demand which by any provision of this Indenture is required or
permitted to be given or served by the Trustee or by the holders of Securities
to or on the Company may be given or served by being deposited postage prepaid,
first-class mail (except as otherwise specifically provided herein) addressed
(until another address of the Company is filed by the Company with the Trustee)
to Schein Pharmaceutical, Inc., 100 Campus Drive, Florham Park, NJ 07932, Chief
Financial Officer with a copy to the General Counsel. Any notice, direction,
request or demand by the Company or any Securityholder to or upon the Trustee
shall be deemed to have been sufficiently given or made, for all purposes, if
given or made at the Corporate Trust Office.

     Where this Indenture provides for notice to Holders, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed,
<PAGE>
 
                                                                              71


first-class postage prepaid, to each Holder entitled thereto, at his last
address as it appears in the Security register. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

     In case, by reason of the suspension of or irregularities in regular mail
service, it shall be impracticable to mail notice to the Company and
Securityholders when such notice is required to be given pursuant to any
provision of this Indenture, then any manner of giving such notice as shall be
satisfactory to the Trustee shall be deemed to be a sufficient giving of such
notice.

     SECTION 12.5 Officers' Certificates and Opinions of Counsel; Statements to
Be Contained Therein. Upon any application or demand by the Company to the
Trustee to take any action under any of the provisions of this Indenture, the
Company shall furnish to the Trustee an Officers' Certificate stating that all
conditions precedent provided for in this Indenture relating to the proposed
action have been complied with and an Opinion of Counsel stating that in the
opinion of such counsel all such conditions precedent have been complied with,
except that in the case of any such application or demand as to which the
furnishing of such documents is specifically required by any provision of this
Indenture relating to such particular application or demand, no additional
certificate or opinion need be furnished.

     Each certificate or opinion provided for in this Indenture and delivered to
the Trustee with respect to compliance with a condition or covenant provided for
in this Indenture shall include (a) a statement that the person making such
certificate or opinion has read such covenant or condition, (b) a brief
statement as to the nature and scope of the examination or investigation upon
which the statements or opinions contained in such certificate or opinion are
based, (c) a statement that, in the opinion of such person, he has made such
examination or investigation as is necessary to enable him to express an
informed opinion as to whether or not such covenant or condition has been
complied with and (d) a statement as to whether or not, in the opinion of such
person, such condition or covenant has been complied with.

     Any certificate, statement or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of
or representations by counsel, unless such officer knows that the certificate or
opinion or representations with respect to the matters upon which his
certificate, statement or opinion may be based as aforesaid are erroneous, or in
the exercise of reasonable care should know that the same are erroneous. Any
certificate, statement or opinion of counsel may be based, insofar as it relates
to factual matters and information in the possession of the Company, upon the
certificate, statement or opinion of or representations by an officer or
officers of the Company, unless such counsel knows that the certificate,
statement or opinion or representations with respect to
<PAGE>
 
                                                                              72


the matters upon which his certificate, statement or opinion may be based as
aforesaid are erroneous, or in the exercise of reasonable care should know that
the same are erroneous.

     Any certificate, statement or opinion of an officer of the Company or of
counsel may be based, insofar as it relates to accounting matters, upon a
certificate or opinion of or representations by an accountant or firm of
accountants in the employ of the Company, unless such officer or counsel, as the
case may be, knows that the certificate or opinion or representations with
respect to the accounting matters upon which his certificate, statement or
opinion may be based as aforesaid are erroneous, or in the exercise of
reasonable care should know that the same are erroneous.

     Any certificate or opinion of any independent firm of public accountants
filed with the Trustee shall contain a statement that such firm is independent.

     SECTION 12.6 Payments Due on Saturdays; Sundays and Holidays. If the date
of maturity of interest on or principal of the Securities or the date fixed for
redemption of any Security shall not be a Business Day, then payment of interest
or principal need not be made on such date, but may be made on the next
succeeding Business Day with the same force and effect as if made on the date of
maturity or the date fixed for redemption, and no interest shall accrue for the
period after such date.

     SECTION 12.7 Conflict of Any Provision of Indenture with Trust Indenture
Act. If and to the extent that any provision of this Indenture limits, qualifies
or conflicts with another provision included in this Indenture by operation of
Sections 310 to 317, inclusive, of the Trust Indenture Act (an "incorporated
provisions), such incorporated provision shall control.

     SECTION 12.8 APPLICABLE LAW. THIS INDENTURE AND EACH SECURITY SHALL BE
DEEMED TO BE A CONTRACT UNDER THE LAWS OF THE STATE OF NEW YORK, AND FOR ALL
PURPOSES SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF SAID STATE, WITHOUT
GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT
THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

     SECTION 12.8 Counterparts. This Indenture may be executed in any number of
counterparts, each of which shall be an original; but such counterparts shall
together constitute but one and the same instrument.

     SECTION 12.9 Effect of Headings. The Article and Section headings herein
and the Table of Contents are for convenience only and shall not affect the
construction hereof.

                                  ARTICLE XIII

                            REDEMPTION OF SECURITIES

     SECTION 13.1 Right of Optional Redemption; Prices. At any time or from time
to time prior to the date which is two years after the Issue Date the Company
may redeem Securities having a principal amount of up to 35% of the original
aggregate principal amount of the Securities within 60 days following one or
more Public Equity Offerings with the net proceeds of such offerings at a
redemption price equal to 110.0% of the principal amount thereof, together with
the accrued and unpaid interest, if any, to the date of redemption (subject to
the right of holders of record on relevant record dates to receive interest due
on relevant interest payment dates); provided that immediately after giving
effect to each such redemption, at least 65% of the original aggregate principal
amount of the Securities remains outstanding.

     SECTION 13.2 Applicability of Article. Redemption of Securities at the
election of the Company or otherwise, as permitted or required by any provision
of this Indenture, shall be made in accordance with such provision and this
Article.

     SECTION 13.3 Election to Redeem; Notice to Trustee. The election of the
Company to redeem any Securities pursuant to Section 13.1 shall be evidenced by
a resolution of the Board of Directors. In case of any redemption at the
election of the Company, the Company shall, at least 60 days prior to the
redemption date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such redemption date and of
the principal amount of Securities to be redeemed and shall deliver to the
Trustee such documentation and records as shall enable the Trustee to select the
Securities to be redeemed pursuant to Section 13.4(e).

     SECTION 13.4 Notice of Redemption; Partial Redemptions. (a) Notice of
redemption to the holders of Securities to be redeemed as a whole or in part
shall be given by mailing notice of such redemption by first class mail, postage
prepaid, at least 30 days and not more than 60 days prior to the date fixed for
redemption to such holders of Securities at their last addresses as they shall
appear upon the registry books. Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not
the holder receives the notice. Failure to give notice by mail, or any defect in
the notice to the holder of any Security designated for redemption as a whole or
in part shall not affect the validity of the proceedings for the redemption of
any other Security.

     (b) The notice of redemption to each such holder shall specify the
principal amount of each Security held by such holder to be redeemed, the date
fixed for redemption, the redemption price, the place or places of payment, that
payment will be made upon presentation and surrender of such Securities, that
such redemption is pursuant to the mandatory or optional sinking fund, or both
if such be the case, that interest accrued to the date fixed for redemption will
be paid as specified in said notice and that on and after said date interest
thereon or on the portions thereof to be redeemed will cease to accrue. In case
any Security is to be redeemed in part only the notice of redemption shall state
the portion of

                                                                              74


the principal amount thereof to be redeemed and shall state that on and after
the date fixed for redemption, upon surrender of such Security, a new Security
or Securities in principal amount equal to the unredeemed portion thereof will
be issued.

     (c) The notice of redemption of Securities to be redeemed at the option of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

     (d) At least one business day prior to the redemption date specified in the
notice of redemption given as provided in this Section, the Company will deposit
with the Trustee or with one or more paying agents (or, if the Company is acting
as its own paying agent, set aside, segregate and hold in trust as provided in
Section 3.4) an amount of money sufficient to redeem on the redemption date all
the Securities so called for redemption at the appropriate redemption price,
together with accrued interest to the date fixed for redemption. If less than
all the outstanding Securities are to be redeemed the Company will deliver to
the Trustee at least 60 days prior to the date fixed for redemption an Officers'
Certificate stating the aggregate principal amount of Securities to be redeemed.

     (e) The Trustee shall select the Securities or portions thereof, either pro
rata or by such method as the Trustee shall deem fair and appropriate,
securities to be redeemed in whole or in part. Securities may be redeemed in
part in multiples of $1,000 only. The Trustee shall, upon the request of the
Company, promptly notify the Company in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption,
the principal amount thereof to be redeemed. For all purposes of this Indenture,
unless the context otherwise requires, all provisions relating to the redemption
of Securities shall relate, in the case of any Security redeemed or to be
redeemed only in part, to the portion of the principal amount of such Security
which has been or is to be redeemed.

     SECTION 13.5 Payment of Securities Called for Redemption. (a) If notice of
redemption has been given as above provided, the Securities or portions of
Securities specified in such notice shall become due and payable on the date and
at the place stated in such notice at the applicable redemption price, together
with interest accrued to the date fixed for redemption, and on and after said
date (unless the Company shall default in the payment of such Securities at the
redemption price, together with interest accrued to said date) interest on the
Securities or portions of Securities so called for redemption shall cease to
accrue and, except as provided in Sections 5.5 and 9.6, such Securities shall
cease from and after the date fixed for redemption to be entitled to any benefit
or security under this Indenture, and the holders thereof shall have no right in
respect of such Securities except the right to receive the redemption price
thereof and unpaid interest to the date fixed for redemption. On presentation
and surrender of such Securities at a place of payment specified in said notice,
said Securities or the specified portions thereof shall be paid and redeemed by
the Company at the applicable redemption price, together with interest accrued
thereon to the date fixed for redemption; provided that any semi-annual payment
of interest becoming due on the date fixed for redemption shall be payable to
the holders of such Securities registered as such on the relevant record date
subject to the terms and provisions of Section 2.4.

     (b) If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal shall, until paid or duly
provided for, bear interest from the date fixed for redemption at the rate borne
by the Security.

     (c) Upon presentation of any Security redeemed in part only, the Company
shall execute and the Trustee shall authenticate and deliver to or on the order
of the holder thereof, at the expense of the Company, a new Security or
Securities, of authorized denominations, in principal amount equal to the
unredeemed portion of the Security so presented.

     SECTION 13.6 Exclusion of Certain Securities from Eligibility for Selection
for Redemption. Securities shall be excluded from eligibility for selection for
redemption if they are identified by registration and certificate number in a
written statement signed by an authorized officer of the Company and delivered
to the Trustee at least 40 days prior to the last date on which notice of
redemption may be given as being owned of record and beneficially by, and not
pledged or hypothecated by either (a) the Company or (b) an entity specifically
identified in such written statement directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company.

     Schein Pharmaceutical, Inc., a Delaware corporation (the "Company"), for
value received hereby promises to pay to or registered assigns the principal sum
of ___________ Dollars on [five years from the date of issue], in such coin or
currency of the United States of America as at the time of payment shall be
legal tender for the payment of public and private debts, and to pay interest at
a rate per annum equal to the greatest of (i) the Treasury Rate (as defined
below) on the date of issuance of this Security plus 6.00% and (ii) the Bear
Stearns High Yield Single B Index Rate on the date of issuance of this Security
plus 1.75%; for purposes hereof, the "Treasury Rate" means (x) the rate borne by
direct obligations of the United States maturing on the fifth anniversary of the
date of issuance of this Security or (y) if there are no such obligations, the
rate determined by linear interpolation between the rates borne by the two
direct obligations of the United States maturing closest to, but straddling the
fifth anniversary of the date of issuance of this Security, in each case as
published by the Board of Governors.

     The Company shall pay interest semiannually on February 1 and August 1, of
each year, commencing with August 1, 199_. Interest on the Securities will
accrue from the most recent interest payment date to which interest on the
Securities has been paid or duly provided for, or if no interest has been paid
or duly provided for on the Securities, from [date of issue], until payment of
said principal sum has been made or duly provided for. Notwithstanding the
foregoing, if the date hereof is after January 15 or July 15, as the case



                                      A-2
<PAGE>
 
may be, and before the following February 1 or August 1, this Security shall
bear interest from such February 1 or August 1; provided that if the Company
shall default in the payment of interest due on such February 1 or August 1,
then this Security shall bear interest from the next preceding February 1 or
August 1 to which interest on the Securities has been paid or duly provided for,
or, if no interest has been paid or duly provided for on the Securities since
the original issue date of this Security. The interest so payable on any
February 1 or August 1 will, except as otherwise provided in the Indenture
referred to on the reverse hereof, be paid to the person in whose name this
Security is registered at the close of business on the January 15 or July 15
preceding such February 1 or August 1, whether or not such day is a business
day; provided that interest may be paid, at the option of the Company, by
mailing a check therefor payable to the registered holder entitled thereto at
his last address as it appears on the Security register.

     Interest on this Security will be calculated on the basis of a 360-day
year, consisting of twelve 30-day months.

     Reference is made to the further provisions set forth on the reverse
hereof. Such further provisions shall for all purposes have the same effect as
though fully set forth at this place.

     This Security shall not be valid or obligatory until the certificate of
authentication hereon shall have been duly signed by the Trustee acting under
the Indenture.

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed under its corporate seal.

                           SCHEIN PHARMACEUTICAL, INC.
                  Senior Subordinated Conversion Notes due 2003

     This Security is one of a duly authorized issue of debt securities of the
Company, limited to the aggregate principal amount of $103,500,000 (except as
otherwise provided in the Indenture mentioned below), issued or to be issued
pursuant to an Indenture dated as of ________________ , 199_ (the "Indenture"),
duly executed and delivered by the Company and the Guarantors to the Trustee
(herein called the "Trustee"). The terms of the Securities include those stated
in the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as in effect on the date of the Indenture (the "Trust
Indenture Act"). Capitalized terms used herein and not defined have the meanings
ascribed thereto in the Indenture. The Securities are subject to all such terms
and Securityholders are referred to the Indenture and the Trust Indenture Act
for a statement of those terms. The terms of the Indenture shall govern any
inconsistencies between the Indenture and the Securities.

     This Security is one of the Initial Notes referred to in the Indenture. The
Securities include the Initial Notes and the Conversion Notes issued in exchange
for the Initial Notes pursuant to the Indenture and the Registration Rights
Agreement. The Initial Notes and the Conversion Notes are treated as a single
class of securities under the Indenture.

     Each Guarantor (on a senior subordinated basis) has jointly and severally
guaranteed, pursuant to Article XI of the Indenture, the due and punctual
payment of the principal of, premium (if any) and interest on the Securities and
all other amounts payable by the Company under the Indenture and the Securities
when and as the same shall be due and payable, whether at maturity, by
acceleration or otherwise, according to the terms of the Securities and the
Indenture.

     The Securities are subordinated to Senior Indebtedness. To the extent
provided in the Indenture, Senior Indebtedness must be paid before the
Securities may be paid. The Company, the Guarantors and each Securityholder by
accepting a Security agree to the subordination provisions contained in Article
X of the Indenture and authorize the Trustee to give them effect and appoint the
Trustee as attorney-in-fact for such purpose.

     The Securities will bear interest at the rate per annum set forth on the
face of this Security.

     In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all the Securities may be declared
due and payable, in the manner and with the effect, and subject to the
conditions, provided in the Indenture. The Indenture provides that in certain
events such declaration and its consequences may be waived by the holders of a
majority in aggregate principal amount of the Securities then outstanding and
that, prior to any such declaration, such holders may waive any past default
under the Indenture and its consequences except a default in the payment of
principal of or premium, if any, or interest on any of the Securities. Any such
consent or waiver by the holder of this



                                      A-4
<PAGE>
 
Security (unless revoked as provided in the Indenture) shall be conclusive and
binding upon such holder and upon all future holders and owners of this Security
and any Security which may be issued in exchange or substitution herefor,
whether or not any notation thereof is made upon this Security or such other
Securities.

     Subject to certain exceptions set forth in the Indenture, the Indenture or
the Securities may be amended with the written consent of the Holders of at
least a majority in outstanding principal amount of the Securities; provided
that no such amendment shall (a) reduce the amount of Securities whose Holders
must consent to an amendment; (b) reduce the rate of or extend the time for
payment of interest on any Security; (c) reduce the principal of or extend the
Stated Maturity of any Security; (d) reduce the premium payable upon the
redemption or repurchase of any Security or change the time at which any
Security may or shall be redeemed or repurchased in accordance with this
Indenture; (e) make any Security payable in money other than that stated in the
Security; (f) modify or affect in any manner adverse to the Holders the terms
and conditions of the obligation of the Company for the due and punctual payment
of the principal of or interest on Securities; or (g) make any change in Section
4.4 or 4.7 of the Indenture or the second sentence of Section 7.2 of the
Indenture, without the consent of each holder of Securities affected by such
amendment.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligations of the Company or the
Guarantors, which are absolute and unconditional, to pay the principal of and
premium, if any, and interest on this Security at the place, times, and rate,
and in the currency, herein prescribed.

     The Securities are issuable only as registered Securities without coupons
in denominations of $1,000 and any multiple of $1,000.

     The Securities may be exchanged for a like aggregate principal amount of
Securities of other authorized denominations in accordance with and subject to
the limitations provided in the Indenture.

     Upon due presentment for registration of transfer of this Security, a new
Security or Securities of authorized denominations, for a like aggregate
principal amount, will be issued to the transferee as provided in the Indenture.
No service charge shall be made for any such transfer, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto.

     At any time or from time to time prior to the date which is two years after
the Issue Date the Company may redeem Securities having a principal amount of up
to 35% of the original aggregate principal amount of the Securities within 60
days following one or more Public Equity Offerings with the net proceeds of such
offerings at a redemption price equal to 110.0% of the principal amount thereof,
together with the accrued and unpaid interest, if any, to the date of redemption
(subject to the right of Holders of record on relevant record dates to receive
interest due on relevant interest payment dates); provided that immediately
after giving effect to each such redemption, at least 65% of the original
aggregate principal amount of the Securities remains outstanding.


                                      A-5

     Subject to payment by the Company of a sum sufficient to pay the amount due
on redemption, interest on this Security (or portion hereof if this Security is
redeemed in part) shall cease to accrue upon the date duly fixed for redemption
of this Security (or portion hereof if this Security is redeemed in part).

     The election of the Company to redeem any Securities pursuant to Section
13.1 of the Indenture shall be evidenced by a resolution of the Board of
Directors. In case of any redemption at the election of the Company, the Company
shall, at least 60 days prior to the redemption date fixed by the Company
(unless a shorter notice shall be satisfactory to the Trustee), notify the
Trustee of such redemption date and of the principal amount of Securities to be
redeemed and shall deliver to the Trustee such documentation and records as
shall enable the Trustee to select the Securities to be redeemed pursuant to
Section 13.4(e) of the Indenture.

     In the event of a Change of Control, the Company will make a Change of
Control Offer to purchase all of the Securities outstanding at a price equal to
101% of the principal amount of the Securities to be repurchased plus accrued
and unpaid interest thereon to the date of purchase, pursuant to an offer made
in conformity with the procedures set forth in Section 3.15 of the Indenture.

     In the event of certain Asset Dispositions, subject to certain conditions,
the Company will make an Offer to purchase an aggregate principal amount of
Securities outstanding equal to the amount of Net Available Cash at a price
equal to 100% of the principal amount of the Securities to be repurchased plus
accrued and unpaid interest thereon to the date of purchase.

     The Company, the Trustee, and any authorized agent of the Company or the
Trustee may deem and treat the registered Holder hereof as the absolute owner of
this Security (whether or not this Security shall be overdue and notwithstanding
any notation of ownership or other writing hereon made by anyone other than the
Company or the Trustee or any authorized agent of the Company or the Trustee),
for the purpose of receiving payment of, or on account of, the principal hereof
and premium, if any, and, subject to the provisions on the face hereof, interest
hereon and for all other purposes, and neither the Company nor the Trustee nor
any authorized agent of the Company or the Trustee shall be affected by any
notice to the contrary. So long as the Depository, or its nominee, is the
registered holder of the Restricted Global Security for the Initial Notes, the
Depository, or its nominee, will be considered the absolute owner of the Initial
Notes represented by the Restricted Global Security for all purposes under the
Indenture and this Security. Owners of beneficial interests in the Restricted
Global Security will not be considered the owners or Holders of any Securities.

     The Securities are subject to defeasance as described in the Indenture.

     No recourse shall be had for the payment of the principal of and premium,
if any, or the interest on this Security, for any claim based hereon, or
otherwise in respect hereof, or based on or in respect of the Indenture or any
indenture supplemental thereto, against any incorporator, shareholder, officer
or director, as such, past, present or future, of

the Company or of any successor corporation, either directly or through the
Company or any successor corporation, whether by virtue of any constitution,
statute or rule of law or by the enforcement of any assessment or penalty or
otherwise, all such liability being, by the acceptance hereof and as part of the
consideration for the issue hereof, expressly waived and released.

                Senior Subordinated Conversion Notes due 20__

     Schein Pharmaceutical, Inc., a Delaware corporation (the "Company"), for
value received hereby promises to pay to or registered assigns the principal sum
of                 Dollars on [five years from the date of issue], in such coin
or currency of the United States of America as at the time of payment shall be
legal tender for the payment of public and private debts, and to pay interest at
a rate per annum equal to the greatest of (i) the Treasury Rate (as defined
below) on the date of issuance of this Security plus 6.00% and (ii) the Bear
Stearns High Yield Single B Index Rate on the date of issuance of this Security
plus 1.75%; for purposes hereof, the "Treasury Rate" means (x) the rate borne by
direct obligations of the United States maturing on the fifth anniversary of the
date of issuance of this Security or (y) if there are no such obligations, the
rate determined by linear interpolation between the rates borne by the two
direct obligations of the United States maturing closest to, but straddling the
fifth anniversary of the date of issuance of this Security, in each case as
published by the Board of Governors of the Federal Reserve System.

     The Company shall pay interest semiannually on February 1 and August 1, of
each year, commencing with August 1, 199_. Interest on the Securities will
accrue from the most recent interest payment date to which interest on the
Securities has been paid or duly provided for, or if no interest has been paid
or duly provided for on the Securities, from [date of issue], until payment of
said principal sum has been made or duly provided for. Notwithstanding the
foregoing, if the date hereof is after January 15 or July 15, as the case may
be, and before the following February 1 or August 1, this Security shall bear
interest from such February 1 or August 1; provided that if the Company shall
default in the payment of interest due on such February 1 or August 1, then this
Security shall bear interest from the next preceding February l or August 1 to
which interest on the Securities has been paid or duly provided for, or, if no
interest has been paid or duly provided for on the Securities since the original
issue date of this Security. The interest so payable on any February l or August
1 will, except as otherwise provided in the Indenture referred to on the reverse
hereof, be paid to the person in whose name this Security is registered at the
close of business on the January 15 or July 15 preceding such February 1 or
August 1, whether or not such day is a business day; provided that interest may
be paid, at the option of the Company, by mailing a check therefor payable to
the registered holder entitled thereto at his last address as it appears on the
Security register.


                                      B-1

     Interest on this Security will be calculated on the basis of a 360-day
year, consisting of twelve 30-day months.

     Reference is made to the further provisions set forth on the reverse
hereof. Such further provisions shall for all purposes have the same effect as
though fully set forth at this place.

     This Security shall not be valid or obligatory until the certificate of
authentication hereon shall have been duly signed by the Trustee acting under
the Indenture.

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed under its corporate seal.

               ___% Senior Subordinated Conversion Notes due 2003

     This Security is one of a duly authorized issue of debt securities of the
Company, limited to the aggregate principal amount of $103,500,000 (except as
otherwise provided in the Indenture mentioned below), issued or to be issued
pursuant to an Indenture dated as of ______, 199_ (the "Indenture"), duly
executed and delivered by the Company and the Guarantors to ____________,
Trustee (herein called the "Trustee"). The terms of the Securities include those
stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939, as in effect on the date of the Indenture (the
"Trust Indenture Act"). Capitalized terms used herein and not defined have the
meanings ascribed thereto in the Indenture. The Securities are subject to all
such terms and Securityholders are referred to the Indenture and the Trust
Indenture Act for a statement of those terms. The terms of the Indenture shall
govern any inconsistencies between the Indenture and the Securities.

     This Security is one of the Conversion Notes referred to in the Indenture.

     Each Guarantor (on a senior subordinated basis) has jointly and severally
guaranteed, pursuant to Article XI of the Indenture, the due and punctual
payment of the principal of, premium (if any) and interest on the Securities and
all other amounts payable by the Company under the Indenture and the Securities
when and as the same shall be due and payable, whether at maturity, by
acceleration or otherwise, according to the terms of the Securities and the
Indenture.

     The Securities are subordinated to Senior Indebtedness. To the extent
provided in the Indenture, Senior Indebtedness must be paid before the
Securities may be paid. The Company, the Guarantors and each Securityholder by
accepting a Security agree to the subordination provisions contained in Article
X of the Indenture and authorize the Trustee to give them effect and appoint the
Trustee as attorney-in-fact for such purpose.

     The Securities will bear interest at the rate per annum set forth on the
face of this Security.

     In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all the Securities may be declared
due and payable, in the manner and with the effect, and subject to the
conditions, provided in the Indenture. The Indenture provides that in certain
events such declaration and its consequences may be waived by the holders of a
majority in aggregate principal amount of the Securities then outstanding and
that, prior to any such declaration, such holders may waive any past default
under the Indenture and its consequences except a default in the payment of
principal of or premium, if any, or interest on any of the Securities. Any such
consent or waiver by the holder of this


                                      B-3
<PAGE>
 
Security (unless revoked as provided in the Indenture) shall be conclusive and
binding upon such holder and upon all future holders and owners of this Security
and any Security which may be issued in exchange or substitution herefor,
whether or not any notation thereof is made upon this Security or such other
Securities.

     Subject to certain exceptions set forth in the Indenture, the Indenture or
the Securities may be amended with the written consent of the Holders of at
least a majority in outstanding principal amount of the Securities; provided
that no such amendment shall (a) reduce the amount of Securities whose Holders
must consent to an amendment; (b) reduce the rate of or extend the time for
payment of interest on any Security; (c) reduce the principal of or extend the
Stated Maturity of any Security; (d) reduce the premium payable upon the
redemption or repurchase of any Security or change the time at which any
Security may or shall be redeemed or repurchased in accordance with this
Indenture; (e) make any Security payable in money other than that stated in the
Security; (f) modify or affect in any manner adverse to the Holders the terms
and conditions of the obligation of the Company for the due and punctual payment
of the principal of or interest on Securities; or (g) make any change in Section
4.4 or 4.7 of the Indenture or the second sentence of Section 7.2 of the
Indenture, without the consent of each holder of Securities affected by such
amendment.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligations of the Company or the
Guarantors, which are absolute and unconditional, to pay the principal of and
premium, if any, and interest on this Security at the place, times, and rate,
and in the currency, herein prescribed.

     The Securities are issuable only as registered Securities without coupons
in denominations of $1,000 and any multiple of $1,000.

     The Securities may be exchanged for a like aggregate principal amount of
Securities of other authorized denominations in accordance with and subject to
the limitations provided in the Indenture.

     Upon due presentment for registration of transfer of this Security, a new
Security or Securities of authorized denominations, for a like aggregate
principal amount, will be issued to the transferee as provided in the Indenture.
No service charge shall be made for any such transfer, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto.

     At any time or from time to time prior to the date which is two years from
the Issue Date the Company may redeem Securities having a principal amount of up
to 35% of the original aggregate principal amount of the Securities within 60
days following one or more Public Equity Offerings with the net proceeds of such
offerings at a redemption price equal to 110.0% of the principal amount thereof,
together with the accrued and unpaid interest, if any, to the date of redemption
(subject to the right of holders of record on relevant record dates to receive
interest due on relevant interest payment dates); provided that


                                      B-4
<PAGE>
 
immediately after giving effect to each such redemption, at least 65% of the
original aggregate principal amount of the Securities remains outstanding.

     Subject to payment by the Company of a sum sufficient to pay the amount due
on redemption, interest on this Security (or portion hereof if this Security is
redeemed in part) shall cease to accrue upon the date duly fixed for redemption
of this Security (or portion hereof if this Security is redeemed in part).

     The election of the Company to redeem any Securities pursuant to Section
13.1 of the Indenture shall be evidenced by a resolution of the Board of
Directors. In case of any redemption at the election of the Company, the Company
shall, at least 60 days prior to the redemption date fixed by the Company
(unless a shorter notice shall be satisfactory to the Trustee), notify the
Trustee of such redemption date and of the principal amount of Securities to be
redeemed and shall deliver to the Trustee such documentation and records as
shall enable the Trustee to select the Securities to be redeemed pursuant to
Section 13.4(e) of the Indenture.

     In the event of a Change of Control, the Company will make a Change of
Control Offer to purchase all of the Securities outstanding at a price equal to
101% of the principal amount of the Securities to be repurchased plus accrued
and unpaid interest thereon to the date of purchase, pursuant to an offer made
in conformity with the procedures set forth in Section 3.15 of the Indenture.

     In the event of certain Asset Dispositions, subject to certain conditions,
the Company will make an Offer to purchase an aggregate principal amount of
Securities outstanding equal to the amount of Net Available Cash at a price
equal to 100% of the principal amount of the Securities to be repurchased plus
accrued and unpaid interest thereon to the date of purchase.

     The Company, the Trustee, and any authorized agent of the Company or the
Trustee may deem and treat the registered Holder hereof as the absolute owner of
this Security (whether or not this Security shall be overdue and notwithstanding
any notation of ownership or other writing hereon made by anyone other than the
Company or the Trustee or any authorized agent of the Company or the Trustee),
for the purpose of receiving payment of, or on account of, the principal hereof
and premium, if any, and, subject to the provisions on the face hereof, interest
hereon and for all other purposes, and neither the Company nor the Trustee nor
any authorized agent of the Company or the Trustee shall be affected by any
notice to the contrary.

     The Securities are subject to defeasance as described in the Indenture.

     No recourse shall be had for the payment of the principal of and premium,
if any, or the interest on this Security, for any claim based hereon, or
otherwise in respect hereof, or based on or in respect of the Indenture or any
indenture supplemental thereto,

exemption from registration provided by Rule 144 under the Securities Act (if
available), or (F) pursuant to an effective registration statement under the
Securities Act.

     2. We understand that, on any proposed resale of Securities, we will be
required to furnish to the Trustee and the Company such certification, legal
opinions and other information as the Trustee and the Company may reasonably
require to confirm that the proposed sale complies with the foregoing
restrictions.

     3. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of our investment in the Securities, and we
and any accounts for which we are acting are each able to bear the economic risk
of our or their investment, as the case may be.

     4. We are a corporation, partnership or other entity or person having such
knowledge and experience in financial and business matters as to be capable of
evaluating the merits and risks of an investment in the Securities, and we are
(or any account for which we are purchasing is) an Institutional Accredited
Investor, able to bear the economic risk of investment in the Securities.

     5. We are acquiring the Securities for our own account (or for accounts as
to which we exercise sole investment discretion and have authority to make, and
do make, the statements contained in this letter) and not with a view to any
distribution of the Securities, subject, nevertheless, to the understanding that
the disposition of our property shall at all times be and remain within our
control.

     6. We understand that (a) the Securities will be delivered to us in
registered form only and that the certificate delivered to us in respect of the
Securities will bear a legend substantially to the following effect:

          THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES
     SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,
     ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR
     FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH BELOW. BY
     ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A
     "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER THE
     SECURITIES ACT), OR (B) TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS
     AN INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE


                                      D-2
<PAGE>
 
     501(a)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT) (AN "ACCREDITED
     INSTITUTION"), OR (C) IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS
     SECURITY IN AN OFFSHORE TRANSACTION AND (2) AGREES THAT IT WILL NOT, WITHIN
     THREE YEARS AFTER THE ORIGINAL ISSUANCE OF THIS SECURITY, RESELL OR
     OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO SCHEIN PHARMACEUTICAL, INC.
     (THE "COMPANY") OR ANY SUBSIDIARY THEREOF, (B) TO A QUALIFIED INSTITUTIONAL
     BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) TO AN
     ACCREDITED INSTITUTION THAT, PRIOR TO SUCH TRANSFER, FURNISHES (OR HAS
     FURNISHED ON ITS BEHALF BY A U.S. BROKER-DEALER) TO THE TRUSTEE A SIGNED
     LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE
     RESTRICTIONS ON TRANSFER OF THIS SECURITY (THE FORM OF WHICH LETTER CAN BE
     OBTAINED FROM THE TRUSTEE), (D) OUTSIDE THE UNITED STATES IN AN OFFSHORE
     TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT, (E)
     PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE
     SECURITIES ACT (IF AVAILABLE), OR (F) PURSUANT TO AN EFFECTIVE REGISTRATION
     STATEMENT UNDER THE SECURITIES ACT. IN CONNECTION WITH ANY TRANSFER OF THIS
     SECURITY WITHIN THREE YEARS AFTER THE ORIGINAL ISSUANCE HEREOF, IF THE
     PROPOSED TRANSFEREE IS AN ACCREDITED INSTITUTION, THE HOLDER MUST, PRIOR TO
     SUCH TRANSFER, FURNISH TO THE TRUSTEE AND THE COMPANY SUCH CERTIFICATIONS,
     LEGAL OPINIONS OR OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY
     REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
     EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
     REQUIREMENTS OF THE SECURITIES ACT. AS USED HEREIN, THE TERMS "OFFSHORE
     TRANSACTION", "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO
     THEM BY REGULATION S UNDER THE SECURITIES ACT.

     and (b) such certificates will be reissued without the foregoing legend
     only in the event of a disposition of the Securities in accordance with the
     provisions of Section 2.5 of the Indenture.

     7. We agree that we will give to each person to whom we transfer Securities
notice of any restrictions on transfer of Securities.

     8. We acknowledge that the Trustee will not be required to accept for
registration of transfer any Securities acquired by us, except upon presentation
of


                                      D-3
<PAGE>
 
evidence satisfactory to the Company and the Trustee that the restrictions set
forth herein have been complied with.

     9. We acknowledge that the Company, the Trustee and others will rely upon
the truth and accuracy of the foregoing acknowledgments, representations or
agreements and agree that if any of the acknowledgments, representations or
agreements deemed to have been made by our purchase of Notes are no longer
accurate, we shall promptly notify the Company and the Trustee.

     The Company and the Trustee are entitled to rely upon this letter and are
irrevocably authorized to produce this letter or a copy hereof to any interested
party in any administrative or legal proceeding or official inquiry with respect
to the matters covered hereby.

                                             Very truly yours,

       Re: Schein Pharmaceutical, Inc. 
           Senior Subordinated Conversion 
           Notes due 2003

Ladies and Gentlemen:

     This opinion is being furnished to you in connection with the sale by
__________ (the "Transferor") to __________ (the "Purchaser") of $___________
aggregate principal amount of __________ Senior Subordinated Conversion Notes
due 2003 of Schein Pharmaceutical, Inc. (the "Securities").

     We have examined such documents and records as we have deemed appropriate.
In our examination of the foregoing, we have assumed the authenticity of all
documents, the genuineness of all signatures and the due authorization,
execution and delivery of the aforementioned by each of the parties thereto. We
have further assumed the accuracy of the representations contained in the
documents set forth above made by the parties executing such documents. We have
also assumed that the sale of the Securities to the Transferor was exempt from
the registration and prospectus delivery requirements of the Securities Act of
1933, as amended (the "Securities Act").

     Based on the foregoing, we are of the opinion that the sale to the
Purchaser of the Securities does not require registration of such Securities
under the Securities Act.

                                             Very truly yours,

                                      E-1

                 CONVERSION NOTES REGISTRATION RIGHTS AGREEMENT

     This Conversion Notes Registration Rights Agreement (the "Agreement") dated
as of December 20, 1996, is made and entered into by Schein Pharmaceutical,
Inc., a Delaware corporation (together with its successors and assigns, the
"Borrower"), for the benefit of the holders of up to $103,500,000 in principal
amount of Senior Subordinated Conversion Notes (the "Conversion Notes") which
may be issued in connection with certain loans (the "Loans"), which shall be
made to the Borrower pursuant to the Senior Subordinated Loan Agreement (the
"Loan Agreement"), dated as of the date hereof, by and among the Borrower, the
financial institutions party thereto (the "Lenders") and Societe Generate, as
administrative agent for the Lenders (in such capacity, the "Administrative
Agent"). Holders of the Loans and the Conversion Notes, once issued, whether
they are original Lenders of the Loans or original holders of the Conversion
Notes or transferees of such Lenders or original holders, are herein referred to
collectively as the "Holders" and individually as a "Holder." To induce the
Lenders to make the Loans, the Borrower has agreed to provide, as set forth in
this Agreement, registration rights with respect to the Conversion Notes.
Capitalized terms used herein without definition shall have the meanings set
forth in the Loan Agreement.

     1. Securities Subject to This Agreement

     (a) Definitions.

     "Broker-Dealer" means a broker or dealer registered under the Exchange Act.

     "Conversion Date" means the date of issuance of the Conversion Notes.

     "Exchange Act" means the Securities Exchange Act of 1934, as amended, or
any successor statute.

     "Holder" means a holder of a Loan or a Registrable Security.
<PAGE>
 
                                                                               2

     "Registrable Securities" means the Conversion Notes.

     "Securities Act" means the Securities Act of 1933, as amended, or any
successor statute.

     "Selling Holder" means a Holder who is selling Registrable Securities
pursuant to a registration statement.

     "Underwriter" means a securities dealer that purchases any Registrable
Securities as principal and not as part of such dealer's market-making
activities.

     (b) Registrable Securities. Any Registrable Security will cease to be a
Registrable Security when (i) a registration statement covering such Registrable
Security has been declared effective by the Securities and Exchange Commission
(the "Commission") and it has been disposed of pursuant to such effective
registration statement or (ii) it is sold under circumstances in which all of
the applicable conditions of Rule 144 (or any similar provisions then in force)
under the Securities Act are met.

     2. Registration.

     (a) Conversion Notes Shelf Registration. (i) The Borrower shall, not later
than December 1, 1997 (60 days prior to the issuance of the Conversion Notes),
prepare and file with the Commission and thereafter shall use commercially
reasonable efforts to cause to be declared effective no later than the
Conversion Date a registration statement on an appropriate form under the
Securities Act relating to the offer and sale of the Conversion Notes by the
Holders thereof from time to time in accordance with the methods of distribution
set forth in such registration statement and Rule 415 under the Securities Act
("Conversion Notes Shelf Registration").
<PAGE>
 
                                                                               3

     (ii) The Borrower agrees to use commercially reasonable efforts to keep the
registration statement relating to the Conversion Notes Shelf Registration
continuously effective in order to permit the prospectus included therein to be
usable by the Holders of the Conversion Notes for a period of three years from
the Conversion Date or such shorter period that will terminate when all the
Conversion Notes covered by the registration statement have been sold pursuant
to such registration statement; provided that the Borrower shall be deemed not
to have used commercially reasonable efforts to keep the registration statement
effective during the requisite period if it voluntarily takes any action that
would result in Holders of Conversion Notes covered thereby not being able to
offer and sell such Conversion Notes during that period, unless (A) such action
is required by applicable law, rule, regulation or policy, or (B) in the
judgement of the Board of Directors of the Borrower, there is a reasonable
likelihood that the failure to take such voluntary action would adversely affect
any existing or prospective material business situation, transaction, or
negotiation or otherwise materially and adversely affect the Borrower and the
taking of such voluntary action does not cause any such registration statement
not to be effective, or delay the filing of any registration statement, for more
than 90 days. Any such period during which the Borrower fails to keep the
registration statement effective and usable for offers and sales of Conversion
Notes is referred to as a "Suspension Period." A Suspension Period shall
commence on and include the date that the Borrower gives notice that the
registration statement is no longer effective or the prospectus included therein
is no longer usable for offers and sales of Conversion Notes and shall end on
the date when each Selling Holder either receives the copies of the supplemented
or amended prospectus contemplated by Section 5(b) hereof or is advised in
writing by the Borrower that use of the prospectus may be resumed. If one or
more
<PAGE>
 
                                                                               4

Suspension Periods occur, the three-year time period referenced above shall be
extended by the number of days included in each such Suspension Period.

     (b) Registered Exchange Offer. (i) In the event that the Conversion Notes
Shelf Registration is not declared effective pursuant to Section 2(a) above on
or before the Conversion Date, the Borrower shall take such actions as are
necessary or appropriate to permit the Holders of the Conversion Notes to effect
a sale thereof in compliance with Rule 144A under the Securities Act as soon as
practicable after the Conversion Date. In addition, the Borrower shall prepare
and, within 45 days after the Conversion Date, file with the Commission a
registration statement on an appropriate form under the Securities Act with
respect to a proposed offer (the "Registered Exchange Offer") to the Holders of
the Conversion Notes to issue and deliver to such Holders, in exchange for the
Conversion Notes, a like principal amount of debt securities of the Borrower
identical in all material respects to the Conversion Notes (the "Registered
Conversion Notes"), shall use commercially reasonable efforts to cause such
registration statement to become effective under the Securities Act as soon as
practical after filing and in any event no later than 120 days after the
Conversion Date and, upon the effectiveness of that registration statement,
shall commence the Registered Exchange Offer and shall cause the same to remain
open for such period of time (but no longer than 30 days after the commencement
of the Registered Exchange Offer), and to be conducted in accordance with such
procedures, as may be required by the applicable provisions of the Exchange Act,
it being the objective of such Registered Exchange Offer to enable each Holder
electing to exchange such Conversion Notes for Registered Conversion Notes
(assuming that such Holder is not an Affiliate of the Borrower, acquires the
Registered Conversion Notes in the ordinary course of such Holder's business and
has no arrangements
<PAGE>
 
                                                                               5

with any person to participate in the distribution of the Registered Conversion
Notes) to trade such Registered Conversion Notes from and after their receipt
without any limitations or restrictions under the Securities Act or the Exchange
Act and without material restrictions under the securities laws of a substantial
proportion of the several states of the United States.

     (ii) The Borrower shall indicate in a "Plan of Distribution" section
contained in the final prospectus constituting a part of the registration
statement relating to the Registered Exchange Offer that any Broker-Dealer who
holds Conversion Notes that were acquired for its own account as a result of
market-making activities or other trading activities (other than Conversion
Notes acquired directly from the Borrower), may exchange such Conversion Notes
for Registered Conversion Notes pursuant to the Registered Exchange Offer.
However, such Broker-Dealer may be deemed an "underwriter" within the meaning of
the Exchange Act and, therefore, must deliver a prospectus meeting the
requirements of the Exchange Act in connection with any resales of the
Registered Conversion Notes received by it in the Registered Exchange Offer,
which prospectus delivery requirement may be satisfied by the delivery by such
Broker-Dealer of the final prospectus contained in the registration statement
relating to the Registered Exchange Offer. Such "Plan of Distribution" section
also shall state that the delivery by a Broker-Dealer of the final prospectus
relating to the Registered Exchange Offer in connection with resales of
Registered Conversion Notes shall not be deemed an admission by such
Broker-Dealer that it is an "underwriter" within the meaning of the Exchange
Act, and shall contain all other information with respect to the resales of the
Registered Conversion Notes by Broker-Dealers that the Commission may require in
connection therewith, but such "Plan of Distribution" shall not name any such
Broker-Dealer or disclose the amount of Registered Conversion Notes held by any
such
<PAGE>
 
                                                                               6

Broker-Dealer except to the extent required by the Commission as a result of a
change in law, rule, regulation or policy after the date of this Agreement.

     (iii) In connection with such Registered Exchange Offer and the offer and
sale of Registered Conversion Notes by Broker-Dealers as contemplated above, the
Borrower shall take such other and further action, including making appropriate
filings under state securities laws and delivering such number of final
prospectuses relating to the Registered Exchange Offer as any Broker-Dealer
proposing to deliver the same in connection with its resales of Registered
Conversion Notes may reasonably request, as may be necessary to realize the
foregoing objectives. The Borrower shall cause the registration statement
relating to the Registered Exchange Offer to remain continuously effective for a
period of at least 20 Business Days (or longer if required by applicable law)
from the date on which such registration statement is first declared effective,
and shall supplement or amend the prospectus contained therein to the extent
necessary to permit such prospectus (as supplemented or amended) to be delivered
by Broker-Dealers in connection with their resales of Registered Conversion
Notes as aforesaid.

     3. Alternative Conversion Notes Shelf Registration. If, because of any
change in currently prevailing interpretations of the Commission's staff, the
Borrower is not permitted to effect a Registered Exchange Offer, as contemplated
by Section 2(b) hereof, the following provisions shall apply:

     (a) The Borrower shall promptly file with the Commission and thereafter
shall use commercially reasonable efforts to cause to be declared effective no
later than 120 days after the issuance of the Conversion Notes a registration
statement on an appropriate form under the Securities Act relating to the offer
and sale of the Conversion Notes by the
<PAGE>
 
                                                                               7

Holders thereof from time to time in accordance with the methods of distribution
set forth in such registration statement and Rule 415 under the Securities Act
("Alternative Conversion Notes Shelf Registration"). The Borrower will use
commercially reasonable efforts to cause the Alternative Conversion Notes Shelf
Registration to become effective on or prior to the later of (x) the 120th day
after the Conversion Date or (y) the 45th day after the publication of the
change in law or interpretation.

     (b) The Borrower agrees to use commercially reasonable efforts to keep the
registration statement relating to the Alternative Conversion Notes Shelf
Registration continuously effective in order to permit the prospectus included
therein to be usable by the Holders of the Conversion Notes for a period of
three years from the Conversion Date or such shorter period that will terminate
when all the Conversion Notes covered by the registration statement have been
sold pursuant to such registration statement; provided that the Borrower shall
be deemed not to have used commercially reasonable efforts to keep the
registration statement effective during the requisite period if it voluntarily
takes any action that would result in Holders of Conversion Notes covered
thereby not being able to offer and sell such Conversion Notes during that
period, unless (A) such action is required by applicable law, rule, regulation
or policy, or (B) in the judgement of the Board of Directors of the Borrower,
there is a reasonable likelihood that the failure to take such voluntary action
would adversely affect any existing or prospective material business situation,
transaction, or negotiation or otherwise materially and adversely affect the
Borrower and the taking of such voluntary action does not cause any such
registration statement not to be effective, or delay the filing of any
registration statement, for more than 90 days. A Suspension Period, as defined
above, shall commence on and include the date that the Borrower gives notice
that
<PAGE>
 
                                                                               8

the registration statement is no longer effective or the prospectus included
therein is no longer usable for offers and sales of Conversion Notes and shall
end on the date when each Selling Holder either receives the copies of the
supplemented or amended prospectus contemplated by Section 5(b) hereof or is
advised in writing by the Borrower that use of the prospectus may be resumed. If
one or more Suspension Periods occur, the three-year time period referenced
above shall be extended by the number of days included in each such Suspension
Period.

     4. Holdback Agreements.

     (a) Restrictions on Public Sale by Holder of Registrable Securities. Each
Holder whose securities are included in a registration statement hereunder
agrees not to effect any public sale or distribution of the issue being
registered or a similar security of the Borrower or any securities convertible
into or exchangeable or exercisable for such securities, including a sale
pursuant to Rule 144 under the Securities Act, during the 14 days prior to, and
during the 90-day period beginning on, the effective date of such registration
statement (except as part of such registration), if and to the extent requested
by the Borrower in the case of a non-underwritten public offering or if and to
the extent requested by the managing Underwriter or Underwriters in the case of
an underwritten public offering.

     (b) Restrictions on Public Sale by the Borrower and Others. The Borrower
and its Affiliates agree (i) not to effect any public sale or distribution of
any securities similar to the Registrable Securities (except as part of such
registration statement), during the 14 days prior to, and during the 90-day
period beginning on, the effective date of any such registration statement filed
pursuant to Section 2 or 3 hereof; and (ii) that any agreement entered into
after the date of the Agreement pursuant to which the Borrower issues or agrees
to issue any privately placed securities similar to the Registrable Securities
shall contain a provision under
<PAGE>
 
                                                                               9

which holders of such securities agree not to effect any public sale or
distribution of any such securities during the periods described in (i) above,
in each case including a sale pursuant to Rule 144 under the Securities Act
(except as part of any such registration, if permitted).

     5. Registration Procedures.

     In connection with any Conversion Notes Shelf Registration or any
Registered Exchange Offer or Alternative Conversion Notes Shelf Registration,
the Borrower shall use commercially reasonable efforts to:

          (a) prepare and file with the Commission a registration statement on
     any form for which the Borrower then qualifies or which counsel for the
     Borrower shall deem appropriate and which form shall be available for the
     sale of the Registered Conversion Notes or Registrable Securities, as the
     case may be, to be registered thereunder in accordance with the intended
     method of distribution thereof, and use commercially reasonable efforts to
     cause such filed registration statement to become effective and qualify an
     indenture relating to the Conversion Notes or the Registered Conversion
     Notes, as the case may be, substantially in the form of Exhibit C to the
     Loan Agreement (with such appropriate modifications as may be necessary to
     reflect the registration of the Conversion Notes pursuant to Sections 2(a)
     or 2(b)) under the Trust Indenture Act of 1939, as amended; provided (i)
     that before filing a registration statement or prospectus or any amendments
     or supplements thereto, the Borrower will furnish to one counsel selected
     by the Holders who hold, or will hold, as the case may be, a majority in
     principal amount of the Registrable Securities to be covered by such
     registration statement or exchanged pursuant to the Registered Exchange
     Offer, as the case may be, copies of all such documents proposed to be
     filed, which documents will be subject
<PAGE>
 
                                                                              10

     to the review of such counsel, and (ii) that after the filing of the
     registration statement, the Borrower will promptly notify each Holder of
     any stop order issued or threatened by the Commission and take all
     reasonable actions required to prevent the entry of such stop order or to
     remove it if entered;

          (b) furnish to each Holder, prior to filing the registration
     statement, if requested, copies of such registration statement as proposed
     to be filed, and thereafter furnish to such Holder such number of copies of
     such registration statement, each amendment and supplement thereto (in each
     case including all exhibits thereto), the prospectus included in such
     registration statement (including each preliminary prospectus) and such
     other documents as such Holder may reasonably request in connection with
     the Registered Exchange Offer or in order to facilitate the disposition of
     the Registrable Securities owned by such Holder, as the case may be;

          (c) use commercially reasonable efforts to register or qualify such
     Registered Conversion Notes or Registrable Securities, as the case may be,
     under such other securities or blue sky laws of such jurisdictions in the
     United States as may be required in connection with the Registered Exchange
     Offer or as any Selling Holder or managing Underwriter reasonably (in light
     of the intended plan of distribution) requests and do any and all other
     acts and things which may be reasonably necessary or advisable to enable
     such Selling Holder or managing Underwriter to consummate the disposition
     in such jurisdictions of the Registrable Securities owned by such Selling
     Holder; provided that the Borrower will not be required to (i) qualify
     generally to do business in any jurisdiction where it would not otherwise
     be required to qualify but for this paragraph (c), (ii) subject itself to
     taxation in any such jurisdiction or (iii) consent to general service of
     process in any such jurisdiction;
<PAGE>
 
                                                                              11

          (d) use commercially reasonable efforts to cause such Registered
     Conversion Notes or Registrable Securities, as the case may be, to be
     registered with or approved by such other governmental agencies or
     authorities as may be necessary by virtue of the business and operations of
     the Borrower or its Subsidiaries in connection with the Registered Exchange
     Offer or to enable the Selling Holder or Selling Holders thereof to
     consummate the disposition of such Registrable Securities;

          (e) notify each Holder of such Registrable Securities that is named as
     a Selling Holder in any registration statement filed pursuant to this
     Agreement, at any time when a prospectus relating thereto is required to be
     delivered under the Securities Act, of the occurrence of an event requiring
     the preparation of a supplement or amendment to such prospectus so that, as
     thereafter delivered to the purchasers of such Registrable Securities, such
     prospectus will not contain an untrue statement of a material fact or omit
     to state any material fact required to be stated therein or necessary to
     make the statements therein, in the light of the circumstances in which
     they were made, not misleading and promptly make available to each such
     Holder any such supplement or amendment;

          (f) enter into customary agreements (including an underwriting
     agreement in customary form) and take such other actions as are reasonably
     required in order to expedite or facilitate the disposition of such
     Registrable Securities;

          (g) make available for inspection, during normal business hours and on
     reasonable prior notice, by any Selling Holder of such Registrable
     Securities, any Underwriter participating in any disposition pursuant to
     such registration statement and any attorney, accountant or other
     professional retained by any such Selling Holder or Underwriter
     (collectively, the "Inspectors") all financial and other records, pertinent
     corporate documents
<PAGE>
 
                                                                              12

     and properties of the Borrower and its Subsidiaries (collectively, the
     "Records") as shall be reasonably necessary to enable them to exercise
     their due diligence responsibility, and cause the Borrower's and the
     Subsidiaries' officers, directors and employees to supply all information
     reasonably requested to any such Inspectors in connection with such due
     diligence. The Borrower may require the Inspector to agree that Records
     which the Borrower determines, in good faith, to be confidential and any
     Records which it notifies the Inspectors are confidential shall not be
     disclosed by the Inspectors unless (i) the disclosure of such Records is
     necessary to avoid or correct a misstatement or omission of a material fact
     in such registration statement or (ii) the release of such Records is
     ordered pursuant to a subpoena or other order from a court of competent
     jurisdiction. Each Selling Holder of such Registrable Securities agrees,
     and shall cause the Inspectors to agree, that information obtained by it as
     a result of such inspections shall be deemed confidential and shall not be
     used by it for any purpose whatsoever, other than the exercise of its due
     diligence responsibility. Without limiting generality of the preceding
     sentence, each Selling Holder of such Registrable Securities agrees, and
     shall cause the Inspectors to agree, that information obtained by it as a
     result of such inspections shall not be used by it as the basis for any
     market transactions in the securities of the Borrower or its Affiliates
     unless and until such information is made generally available to the
     public. Each Selling Holder of such Registrable Securities further agrees,
     and shall cause the Inspectors to agree, that it will, upon learning that
     disclosure of such Records is sought in a court of competent jurisdiction,
     give notice to the Borrower and allow the Borrower, at its expense, to
     undertake appropriate action to prevent disclosure of the Records deemed
     confidential;
<PAGE>
 
                                                                              13

          (h) in the event such sale is pursuant to an underwritten offering,
     use commercially reasonable efforts to obtain a comfort letter or comfort
     letters from the Borrower's independent public accountants in customary
     form and covering matters of the type customarily covered by comfort
     letters as the managing Underwriter reasonably requests;

          (i) use commercially reasonable efforts to obtain an opinion or
     opinions from counsel for the Borrower in customary form; and

          j) otherwise use commercially reasonable efforts to comply with all
     applicable rules and regulations of the Commission.

     Notwithstanding any other provision of this Agreement, the Borrower may
delay the filing of any registration statement for up to 90 days if (i) the
Borrower would, in the opinion of its counsel, be required to disclose in such
registration statement information not otherwise then required by law to be
publicly disclosed and (ii) in the judgment of the Board of Directors of the
Borrower, there is a reasonable likelihood that such disclosure, or any other
action to be taken in connection with any registration statement, would
adversely affect any existing or prospective material business situation,
transaction, or negotiation or otherwise materially and adversely affect the
Borrower.

     The Borrower may require each Selling Holder of Registrable Securities to
promptly furnish in writing to the Borrower such information regarding the
distribution of the Registrable Securities as it may from time to time
reasonably request and such other information as may be legally required or
reasonably requested in connection with such registration.

     Each Selling Holder agrees that, upon receipt of any notice from the
Borrower of the happening of any event of the kind described in Section 5(e)
hereof, such Selling
<PAGE>
 
                                                                              14

Holder will forthwith discontinue disposition of Registrable Securities pursuant
to the registration statement covering such Registrable Securities until such
Selling Holder's receipt of the copies of the supplemented or amended prospectus
contemplated by Section 5(e) hereof, and, if so directed by the Borrower such
Selling Holder will deliver to the Borrower all copies, other than permanent
file copies then in such Selling Holder's possession, of the most recent
prospectus covering such Registrable Securities at the time of receipt of such
notice.

     6. Registration Expenses.

     In connection with any registration statement required to be filed pursuant
to Section 2 or 3 hereunder, the Borrower shall pay the following registration
expenses (the "Registration Expenses"): (i) all registration and filing fees,
(ii) fees and expenses of compliance with securities or blue sky laws (including
reasonable fees and disbursements of counsel in connection with blue sky
qualifications of the Registered Conversion Notes or Registrable Securities, as
the case may be), (iii) printing expenses, (iv) internal Borrower expenses
(including, without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties), (v) the fees and expenses
incurred in connection with any listing of the Registered Conversion Notes or
Registrable Securities, as the case may be, (vi) fees and disbursements of
counsel for the Borrower and customary fees and expenses for independent
certified public accountants retained by the Borrower (including the expenses of
any comfort letters or costs associated with the delivery by independent
certified public accountants of a comfort letter or comfort letters requested
pursuant to Section 5(h) hereof), (vii) the fees and expenses of any special
experts retained by the Borrower in connection with such registration, and
(viii) reasonable fees and expenses of one counsel (who shall be
<PAGE>
 
                                                                              15

selected by Holders of a majority of the Registrable Securities and who shall be
reasonably acceptable to the Borrower) for the Holders incurred in connection
with the registration hereunder. The Borrower shall not have any obligation to
pay any underwriting fees, discounts or commissions attributable to the sale of
Registrable Securities (including, without limitation, fees and expenses of any
qualified independent Underwriter that may be required under the rules of the
National Association of Securities Dealers), or, except as otherwise provided in
clause (viii) above, any out-of-pocket expenses of the Holders (or any agents
who manage their accounts) or fees and disbursements of any counsel for any
Underwriter in any underwritten offering.

     7. Indemnification; Contribution.

     (a) Indemnification by the Borrower. The Borrower agrees to indemnify and
hold harmless each Selling Holder of Registrable Securities, its officers,
directors, representatives and agents and each person, if any, who controls such
Selling Holder within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act from and against any and all losses, claims, damages,
liabilities and expenses (including reasonable costs of investigation) arising
out of or based upon any untrue statement or alleged untrue statement of a
material fact contained in any registration statement or prospectus relating to
the Registrable Securities or in any amendment or supplement thereto or in any
preliminary prospectus, or arising out of or based upon any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages, liabilities or expenses arise out of, or are based
upon, any such untrue statement or omission or allegation thereof based upon
information furnished in writing to the Borrower by such Selling Holder or on
such Selling
<PAGE>
 
                                                                              16

Holder's behalf expressly for use therein; and provided that with respect to any
untrue statement or omission or alleged untrue statement or omission made in any
preliminary prospectus, the indemnity agreement contained in this paragraph
shall not apply to the extent that any such loss, claim, damage, liability or
expense results from the fact that a current copy of the prospectus was not sent
or given to the person asserting any such loss, claim, damage, liability or
expense at or prior to the written confirmation of the sale of the Registrable
Securities concerned to such person if it is determined that the provision of
such person with a current copy of the prospectus would have cured the defect
giving rise to such loss, claim, damage, liability or expense. The Borrower also
agrees to indemnify, as applicable, (i) the Broker-Dealers who hold Registrable
Securities acquired for their own accounts pursuant to the Registered Exchange
Offer and their officers, directors and each person who controls such
Broker-Dealers, and (ii) the Underwriters of the Registrable Securities and
their officers, directors and each person who controls such Underwriters, on
substantially the same basis as that of the indemnification of the Selling
Holders provided in this Section 7 if such Broker-Dealers and Underwriters agree
in writing to indemnify and contribute to the Borrower on substantially the same
basis as the Selling Holders indemnify and contribute to the Borrower pursuant
to this Section 7.

     (b) Indemnification by Holder of Registrable Securities. Each Selling
Holder whose Registrable Securities are included in a registration pursuant
hereto, shall be deemed to have agreed to indemnify and hold harmless the
Borrower, its directors and officers and each person, if any, who controls the
Borrower within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act from and against any and all losses, claims,
damages, liabilities and expenses (including reasonable costs of
<PAGE>
 
                                                                              17

investigation) arising out of or based upon any untrue statement or alleged
untrue statement of a material fact contained in any registration statement or
prospectus relating to the Registrable Securities or in any amendment or
supplement thereto or in any preliminary prospectus, or arising out of or based
upon any omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
provided that the provisions of this paragraph shall apply only insofar as
losses, claims, damages, liabilities or expenses arise out of, or are based
upon, any such untrue statement or omission or allegation thereof based upon
information furnished in writing by such Selling Holder or on such Selling
Holder's behalf expressly for use in any registration statement or prospectus
relating to the Registrable Securities, or any amendment or supplement thereto,
or any preliminary prospectus. In case any action or proceeding shall be brought
against the Borrower, or its directors or officers, or any such controlling
person, in respect of which indemnity may be sought against such Selling Holder,
such Selling Holder shall have the rights and duties given to the Borrower, and
the Borrower or its directors or officers or such controlling person shall have
the rights and duties given to such Selling Holder, by the preceding paragraph.

     (c) Conduct of Indemnification Proceedings. Promptly after receipt of
notice of the commencement of any action or proceeding (including any
governmental investigation) brought or asserted against any person entitled to
indemnification under clause (a) or (b) above (an "Indemnified Party") in
respect of which indemnity may be sought from any party who has agreed to
provide such indemnification (an "Indemnifying Party"), if a claim in respect
thereof is to be made against an Indemnifying Party under such clause, the
Indemnified Party shall notify the Indemnifying Party in writing of the
commencement
<PAGE>
 
                                                                              18


thereof; provided, that the omission so to notify the Indemnifying Party shall
not relieve it from any liability which it may have under this Section 7 except
to the extent it has been materially prejudiced by such omission; provided,
further, that the omission so to notify the Indemnifying Party shall not relieve
it from any liability which it may have to an Indemnified Party otherwise than
under this Section 7. The Indemnifying Party shall be entitled to assume the
defense thereof, including the employment of counsel reasonably satisfactory to
such Indemnified Party, and shall assume the payment of all expenses indemnified
hereunder. Such Indemnified Party shall have the right to employ separate
counsel in any such action and to participate in the defense thereof, but the
fees and expenses of such separate counsel shall be at the expense of such
Indemnified Party unless (i) the Indemnifying Party has agreed to pay such fees
and expenses or (ii) the named parties to any such action or proceeding
(including any impleaded parties) include both such Indemnified Party and the
Indemnifying Party, and such Indemnified Party shall have been advised by
counsel that there is a conflict of interest on the part of counsel employed by
the Indemnifying Party to represent such Indemnified Party (in which case, if
such Indemnified Party notifies the Indemnifying Party in writing that it elects
to employ separate counsel at the expense of the Indemnifying Party, the
Indemnifying Party shall not have the right to assume the defense of such action
or proceeding on behalf of such Indemnified Party; it being understood, however,
that the Indemnifying Party shall not, in connection with any one such action or
proceeding or separate but substantially similar or related actions or
proceedings in the same jurisdiction arising out of the same general allegations
of circumstances, be liable for the fees and expenses of more than one separate
firm of attorneys (together with appropriate local counsel) at any time for all
such Indemnified Parties, which firm shall be designated in writing by
<PAGE>
 
                                                                              19


such Indemnified Parties). The Indemnifying Party shall not be liable for any
settlement of any such action or proceeding effected without its written
consent, which shall not be unreasonably withheld, but if settled with its
written consent, or if there be a final judgment for the plaintiff in any such
action or proceeding, the Indemnifying Party shall indemnify and hold harmless
such Indemnified Parties from and against any loss or liability (to the extent
stated above) by reason of such settlement or judgment.

     (d) Contribution. If the indemnification provided for in this Section 7 is
due in accordance with the terms hereof but is held to be unavailable to the
Indemnified Parties in respect of any losses, claims, damages, liabilities or
judgments referred to herein (collectively, "losses"), then each such
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such losses (i) as between the Borrower and the Selling Holders on the one
hand and the Underwriters or Broker-Dealers, as the case may be, on the other,
in such proportion as is appropriate to reflect the relative benefits received
by the Borrower and the Selling Holders on the one hand and the Underwriters or
Broker Dealers, as the case may be on the other from the offering of the
Registrable Securities, or if such allocation is not permitted by applicable
law, in such proportion as is appropriate to reflect not only such relative
benefits but also the relative fault of the Borrower and the Selling Holders on
the one hand and of the Underwriters or Broker Dealers, as the case may be, on
the other in connection with the statements or omissions which resulted in such
losses, as well as any other relevant equitable considerations and (ii) as
between the Borrower on the one hand and each Selling Holder on the other, in
such proportion as is appropriate to reflect the relative fault of the Borrower
and of each Selling Holder in connection with such statements or omissions, as
well as any other
<PAGE>
 
                                                                              20


relevant equitable considerations. The relative benefits received by the
Borrower and the Selling Holders on the one hand and the Underwriters or
Broker-Dealers, as the case may be, on the other shall be deemed to be in the
same proportion as the total proceeds from the offering (net of underwriting
discounts and commissions but before deducting expenses) received by the
Borrower and the Selling Holders bear to the total underwriting discounts and
commissions received by the Underwriters or Broker-Dealers, as the case may be,
in each case as set forth in the table on the cover page of the prospectus. The
relative fault of the Borrower and the Selling Holders on the one hand and of
the Underwriters or Broker-Dealers, as the case may be, on the other shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Borrower and the Selling
Holders or by the Underwriters or Broker-Dealers, as the case may be. The
relative fault of the Borrower on the one hand and of each Selling Holder on the
other shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by such party,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

     The Borrower and the Selling Holders agree that it would not be just and
equitable if contribution pursuant to this Section 7(d) were determined by pro
rata allocation (even if the Underwriters or Broker-Dealers, as the case may be,
were treated as one entity for such purpose) or by any other method of
allocation which does not take account of the equitable considerations referred
to in the immediately preceding paragraph. The amount paid or payable by an

                                                                              21


judgments referred to in the immediately preceding paragraph shall be deemed to
include, subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such Indemnified Party in connection with investigating
or defending any such action or claim and for which it is entitled to be
indemnified hereunder. Notwithstanding the provisions of this Section 7(d), no
Underwriter or Broker-Dealer, as the case may be, shall be required to
contribute any amount in excess of the amount by which the total price at which
the Registrable Securities underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages which such Underwriter
or Broker-Dealer, as the case may be, has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission, and no Selling Holder shall be required to contribute any amount in
excess of the amount by which the total price at which the Registrable
Securities of such Selling Holder were offered to the public exceeds the amount
of any damages which such Selling Holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 31(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.

     8. Additional Interest Under Certain Circumstances; Remedies.

     (a) In the event that the Conversion Notes Shelf Registration is not
declared effective pursuant to Section 2(a) above on or before the Conversion
Date, and (i) (A) the Registered Exchange Offer registration statement is not
filed on or prior to the 45th day following the Conversion Date, (B) the
Registered Exchange Offer registration statement is not declared effective on or
prior to the 120th day following the Conversion Date or (C) the
<PAGE>
 
                                                                              22


Registered Exchange Offer is not consummated on or prior to the 150th day
following the Conversion Date or (ii) changes in law or the applicable
interpretation of the Commission staff do not permit the Issuers to effect the
Registered Exchange Offer and (A) an Alternative Conversion Notes Shelf
Registration with respect to the Securities is not promptly filed pursuant to
Section 3(a) hereof, or (B) is not declared effective under the Securities Act
on or prior to the later of (x) the 120th day after the Conversion Date and (y)
the 45th day after the publication of the change in law or interpretation, the
interest rate borne by the Conversion Notes shall be increased by one-half of
one percent per annum following, in the case of clause (i) (A) such 45 day
period, or in the case of clauses (i)(B) or (i)(C), such 120- or 150-day period,
as the case may be or, in the case of clause (ii), such 45- or 120-day period,
as applicable. The aggregate amount of such increase from the original interest
rate pursuant to these provisions will in no event exceed one-half of one
percent per annum. Such increase will cease to be effective on the date of
filing of the Registered Exchange Offer registration statement, effectiveness of
the Registered Exchange Offer registration statement, consummation of the
Registered Exchange Offer or the effectiveness of an Alternative Conversion
Notes Shelf Registration, as the case may be.

     (b) Any amounts of additional interest due pursuant to the paragraph above
will be payable in cash, on the same original interest payment dates as the
Securities. The amount of additional interest will be determined by multiplying
the applicable additional interest rate by the principal amount of the affected
Securities of such Holders, multiplied by a fraction, the numerator of which is
the number of days such additional interest rate was applicable during such
period (determined on the basis of a 360-day year comprised of twelve

                                                                              23


30-day month and, in the case of a partial month, the actual number of days
elapsed), and the denominator of which is 360.

     9. Participation in Underwritten Registrations.

     No person may participate in any underwritten registration hereunder unless
such person (a) agrees to sell such person's securities on the basis provided in
any underwriting arrangements approved by the persons entitled hereunder to
approve such arrangements and (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
reasonably required under the terms of such underwriting arrangements and this
Agreement.

     10. Rule 144.

     To the extent it is otherwise required to do so, the Borrower covenants
that it will file any reports required to be filed by it under the Securities
Act and the Exchange Act so as to enable Holders to sell Registrable Securities
without registration under the Securities Act within the limitation of the
exemptions provided by (a) Rule 144 under the Securities Act, as such Rule may
be amended from time to time, or (b) any similar rule or regulation hereafter
adopted by the Commission. Upon the request of any Holder, the Borrower will
deliver to such Holder a written statement as to whether it has complied with
such requirements.

     11. Miscellaneous.

     (a) No Inconsistent Agreements. The Borrower will not hereafter enter into
and is not presently a party to any agreement with respect to its securities
which conflicts with the rights granted to the Holders of Registrable Securities
in this Agreement.
<PAGE>
 
                                                                              24


     (b) Remedies. Each Holder of Registrable Securities, in addition to being
entitled to exercise all rights granted by law, including recovery of damages,
will be entitled to specific performance of its rights under this Agreement. The
Borrower agrees that monetary damages would not be adequate compensation for any
loss incurred by reason of a breach by it of the provisions of this Agreement
and hereby agrees to waive the defense in any action for specific performance
that a remedy at law would be adequate. Any breach of this Agreement shall not
cause a Default or Event of Default under the Notes.

     (c) Amendments and Waivers. Except as otherwise provided herein, the
provisions of this Agreement may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given
unless the Borrower has obtained the written consent of Holders holding a
majority in principal amount of the Registrable Securities then outstanding
affected by such amendment, modification, supplement, waiver or departure, which
pursuant to the terms of the Loan Agreement may vote on waivers or amendments.

     (d) Notices. All notices and other communications provided for or permitted
hereunder shall be in writing and personally delivered or sent by registered or
certified first-class mail or by telecopy:

          (i) if to a Holder at its last registered address, and with a copy to

accordance with the internal laws of the State of New York applicable to
contracts made and to be performed wholly within that State without regard to
the principles thereof regarding conflict of laws.

     (h) Severability. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstances, is held
invalid, illegal or unenforceable in any respect for any reason, the validity,
legality and enforceability of any such provision in every other respect and of
the remaining provisions contained herein shall not be in any way impaired
thereby, it being intended that all of the rights and privileges of the Holders
shall be enforceable to the fullest extent permitted by law.

                                                           to the Loan Agreement

                         SUBORDINATED GUARANTEE AGREEMENT dated as of December
                    20, 1996, between each Subsidiary from time to time party
                    hereto (each such Subsidiary individually, a "Guarantor" and
                    collectively, the "Guarantors"), and SOCIETE GENERALE, as
                    administrative agent (in such capacity, the "Administrative
                    Agent") for the Lenders (as defined in the Loan Agreement
                    referred to below).

     Reference is made to the Senior Subordinated Loan Agreement dated as of
December 20, 1996 (as amended, restated, supplemented, modified or waived from
time to time, the "Loan Agreement"), among Schein Pharmaceutical, Inc., a
Delaware corporation (the "Borrower"), the financial institutions party thereto
as lenders (the "Lenders"), and Societe Generate, as administrative agent (in
such capacity, the "Administrative Agent").

     The Lenders have agreed to make Loans to the Borrower pursuant to, and upon
the terms and subject to the conditions specified in, the Loan Agreement. The
obligations of the Lenders to make Loans are conditioned on, among other things,
the execution and delivery by the Subsidiary Guarantors of a guarantee agreement
in the form hereof. Capitalized terms used herein and not defined herein shall
have the meanings assigned to such terms in the Loan Agreement.

     Accordingly, the parties hereto agree as follows:

     SECTION 1. Guarantee. Subject to Section 6(b) hereof, each Guarantor
unconditionally guarantees, jointly with the other Guarantors and severally, as
a primary obligor and not merely as a surety, the due and punctual payment of
the Obligations. Each Guarantor further agrees that the Obligations may be
extended or renewed, in whole or in part, without notice to or further assent
from it, and that it will remain bound upon its guarantee notwithstanding any
extension or renewal of any Obligation.

     SECTION 2. Obligations Not Waived. To the fullest extent permitted by
applicable law, each Guarantor waives presentment to, demand of payment from and
protest to the Borrower or any other guarantor of any of the Obligations, and
also waives notice of acceptance of its guarantee and notice of protest for
nonpayment. To the fullest extent permitted by applicable law, the obligations
of each Guarantor hereunder shall not be affected by (a) the failure of the
Administrative Agent or any other Lender to assert any claim or demand or to
exercise or enforce any right or remedy against the Borrower or any other
guarantor under the provisions of this Agreement, any Loan Document or
otherwise; (b) any rescission, waiver, amendment or modification of, or any
release from any of the terms or provisions of this
<PAGE>
 
                                                                               2

Agreement, any other Loan Document, any guarantee or any other agreement,
including with respect to any other Subsidiary Guarantor under this Agreement;
(c) the release of any security held by the Administrative Agent or any other
Lender for the Obligations; or (d) the failure to perfect any security interest
in, or the release of, any of the security held by or on behalf of the
Administrative Agent.

     SECTION 3. Guarantee of Payment. Each Guarantor agrees that its guarantee
constitutes a guarantee of payment when due and not of collection, and waives
any right to require that any resort be had by the Administrative Agent or any
other Lender to collateral security, if any, held for payment of the Obligations
or to any balance of any deposit account or credit on the books of the
Administrative Agent or any other Lender in favor of the Borrower or any other
Person.

     SECTION 4. No Discharge or Diminishment of Guarantee. Except as provided in
Section 6(b) hereof, the obligations of each Guarantor hereunder shall not be
subject to any reduction, limitation, impairment or termination for any reason
(other than the indefeasible payment in full in cash of the Obligations),
including any claim of waiver, release, surrender, alteration or compromise of
any of the Obligations, and shall not be subject to any defense or setoff,
counterclaim, recoupment or termination whatsoever by reason of the invalidity,
illegality or unenforceability of the Obligations or otherwise. Without limiting
the generality of the foregoing, the obligations of each Guarantor hereunder
shall not be discharged or impaired or otherwise affected by the failure of the
Administrative Agent or any other Lender to assert any claim or demand or to
enforce any remedy under the Loan Agreement, any other Loan Document, any other
guarantee or any other agreement, by any waiver or modification of any provision
of any thereof, by any default, failure or delay, wilful or otherwise, in the
performance of the Obligations, or by any other act or omission that may or
might in any manner or to any extent vary the risk of any Guarantor or that
would otherwise operate as a discharge of any Subsidiary Guarantor as a matter
of law or equity (other than the indefeasible payment in full in cash of all the
Obligations).

     SECTION 5. Defenses of Borrower Waived. To the extent permitted by
applicable law, each of the Guarantors waives any defense based on or arising
out of any defense of the Borrower or the unenforceability of the Obligations or
any part thereof from any cause, or the cessation from any cause of the
liability of the Borrower, other than final and indefeasible payment in full in
cash of the Obligations.

     SECTION 6. Subordination. (a) In furtherance of the foregoing and not in
limitation of any other right that the Administrative Agent or any other Lender
has at law or in equity against any Guarantor by virtue hereof, and subject to
Section 6(b) hereof, upon the failure of the Borrower to pay any Obligation when
and as the same shall become due, whether at maturity, by acceleration, after
notice of prepayment or otherwise, each Guarantor hereby promises to and will,
upon receipt of written demand by the Administrative Agent, forthwith pay, or
cause to be paid, to the
<PAGE>
 
                                                                               3

Administrative Agent or such other Lender as is designated thereby in cash the
amount of such unpaid Obligations. Upon payment by any Guarantor of any sums to
the Administrative Agent or any Lender as provided above, all rights of such
Guarantor against the Borrower arising as a result thereof by way of right of
subrogation, contribution, reimbursement, indemnity or otherwise, shall in all
respects be subordinate and junior in right of payments to the prior
indefeasible payment in full in cash of the Obligations. In addition, any
indebtedness of the Borrower now or hereafter held by any Guarantor is hereby
subordinated in right of payment to the Obligations (it being agreed that this
Section 6 shall not prohibit the repayment of such indebtedness so long as no
Default or Event of Default shall have occurred and be continuing, or result
therefrom). If any amount shall be paid to any Guarantor on account of (i) such
subrogation, contribution, reimbursement, indemnity or similar right or (ii) any
such indebtedness of the Borrower, such amount shall be held in trust for the
benefit of the Lenders and shall forthwith be paid to the Administrative Agent
to be credited against the payment of the Obligations, whether matured or
unmatured, in accordance with the terms of the Loan Documents.

     (b) Anything to the contrary herein notwithstanding, this Agreement is
subject to the subordination provisions of Article VIII of the Loan Agreement
which are incorporated herein by reference as if fully set forth herein,
treating the obligations of the Guarantors hereunder and the Obligations
guaranteed hereby, for all purposes, as Subordinated Indebtedness which is
subordinated to the Senior Indebtedness as provided in such Article.

     SECTION 7. Information. Each Guarantor assumes all responsibility for being
and keeping itself informed of the Borrower's financial condition and assets,
and of all other circumstances bearing upon the risk of nonpayment of the
Obligations and the nature, scope and extent of the risks that such Guarantor
assumes and incurs hereunder, and agrees that none of the Administrative Agent
or the other Lenders will have any duty to advise any Guarantor of information
known to it or any of them regarding such circumstances or risks.

     SECTION 8. Representations and Warranties. Each Guarantor represents and
warrants as to itself that all representations and warranties relating to it
contained in the Loan Agreement are true and correct.

     SECTION 9. Termination. (a) The guarantees made hereunder shall terminate
when all the Obligations have been indefeasibly paid in full and shall continue
to be effective or be reinstated, as the case may be, if at any time payment, or
any part thereof, of any Obligation is rescinded or must otherwise be restored
by any Lender or any Guarantor upon the bankruptcy or reorganization of the
Borrower, any Guarantor or otherwise.

                                                                               4

     (b) If at any time shares of the capital stock of any Guarantor shall be
sold in a transaction the Net Cash Proceeds of which are applied in accordance
with the provisions of Section 2.11 of the Loan Agreement which results in such
Guarantor no longer constituting a Subsidiary, the Agent is hereby authorized
and directed to execute and deliver a release of such Guarantor from its
obligations and liabilities under this Guarantee upon receipt by the Agent of
reasonable evidence of compliance with the requirements of this paragraph.

     SECTION 10. Binding Agreement; Assignments. Whenever in this Agreement any
of the parties hereto is referred to, such reference shall be deemed to include
the successors and assigns of such party; and all covenants, promises and
agreements by or on behalf of the Guarantors that are contained in this
Agreement shall bind and inure to the benefit of each party hereto and their
respective successors and assigns. This Agreement shall become effective as to
any Guarantor when a counterpart hereof executed on behalf of such Guarantor
shall have been delivered to the Administrative Agent and a counterpart hereof
shall have been executed on behalf of the Administrative Agent, and thereafter
shall be binding upon such Guarantor and the Administrative Agent and their
respective successors and assigns, and shall inure to the benefit of such
Guarantor, the Administrative Agent and the other Lenders, and their respective
successors and assigns, except that no Guarantor shall have the right to assign
its rights or obligations hereunder or any interest herein (and any such
attempted assignment shall be void), except as expressly contemplated by this
Agreement or the other Loan Documents.

     SECTION 11. Waivers: Amendment. (a) No failure or delay of the
Administrative Agent in exercising any power or right hereunder shall operate as
a waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power. The rights and remedies of the Administrative Agent
hereunder and of the other Lenders under the other Loan Documents are cumulative
and are not exclusive of any rights or remedies that they would otherwise have.
No waiver of any provisions of this Agreement or consent to any departure by any
Guarantor therefrom shall in any event be effective unless the same shall be
permitted by paragraph (b) below, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. No
notice or demand on any Guarantor in any case shall entitle such Guarantor to
any other or further notice or demand in similar or other circumstances.

     (b) Neither this Agreement nor any provision hereof may be waived, amended
or modified except pursuant to a written agreement entered into between the
Guarantors and the Administrative Agent, with the prior written consent of the
Required Lenders (except as otherwise provided in the Loan Agreement).

     SECTION 12. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

     SECTION 13. Notices. All communications and notices hereunder shall be in
writing and given as provided in Section 10.1 of the Loan Agreement. All
communications and notices hereunder to each Guarantor shall be given to it at
its address set forth below, or on Annex I hereto, with a copy to the Borrower.

     SECTION 14. Survival of Agreement; Severability. (a) All covenants,
agreements, representations and warranties made by the Guarantors herein and in
the certificates or other instruments prepared or delivered in connection with
or pursuant to this Agreement or any other Loan Document shall be considered to
have been relied upon by the Administrative Agent and the other Lenders and
shall survive the making by the Lenders of the Loans, regardless of any
investigation made by the Lenders or on their behalf, and shall continue in full
force and effect as long as the principal of or any accrued interest on any Loan
or any fee or other amount payable under the Loan Agreement or any other Loan
Document is outstanding and unpaid and as long as the Commitments have not been
terminated.

     (b) In the event any one or more of the provisions contained in this
Agreement or in any other Loan Document should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein and therein shall not in any way be
affected or impaired thereby (it being understood that the invalidity of a
particular provision in a particular jurisdiction shall not in and of itself
affect the validity of such provision in any other jurisdiction). The parties
shall endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

     SECTION 15. Counterparts. This Agreement may be executed in counterparts,
each of which shall constitute an original, but all of which, when taken
together, shall constitute but one contract, and shall become effective as
provided in Section 11.

     SECTION 16. Rules of Interpretation. The rules of interpretation specified
in Section 1.2 of the Loan Agreement shall be applicable to this Agreement.

     SECTION 17. Jurisdiction; Consent to Service of Process. (a) The
Administrative Agent and each Guarantor hereby irrevocably and unconditionally
submits, for itself and its property, to the nonexclusive jurisdiction of any
New York State court or Federal court of the United States of America sitting in
New York City, and any appellate court from any thereof, in any action or
proceeding arising out of or
<PAGE>
 
                                                                               6

relating to this Agreement or the other Loan Documents, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably
and unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Nothing in this Agreement shall affect any right that the
Administrative Agent or any other Lender may otherwise have to bring any action
or proceeding relating to this Agreement or the other Loan Documents against any
Guarantor or its properties in the courts of any jurisdiction.

     (b) The Administrative Agent and each Guarantor hereby irrevocably and
unconditionally waives, to the fullest extent it may legally and effectively do
so, any objection that it may now or hereafter have to the laying of venue of
any suit, action or proceeding arising out of or relating to this Agreement or
the other Loan Documents in any New York State or Federal court. Each of the
parties hereto hereby irrevocably waives, to the fullest extent permitted by
law, the defense of an inconvenient forum to the maintenance of such action or
proceeding in any such court.

     (c) Each party to this Agreement irrevocably consents to service of process
in the manner provided for notices in Section 13. Nothing in this Agreement will
affect the right of any party to this Agreement to serve process in any other
manner permitted by law.

     SECTION 18. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER
OR IN CONNECTION WITH THIS AGREEMENT. EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK
TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER
PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     SECTION 19. Additional Guarantors. Subject to Section 5.10 of the Loan
Agreement, each Subsidiary (other than Foreign Subsidiaries) that was not in
existence or not such a Subsidiary, on the date of the Loan Agreement is
required to enter into this Guarantee Agreement as a Guarantor upon becoming a
Subsidiary. Upon execution and delivery, after the date hereof, by the
Administrative Agent and
<PAGE>
 
                                                                               7

such a Subsidiary of an instrument in the form of Annex 1, such Subsidiary shall
become a Guarantor hereunder with the same force and effect as if originally
named as a Guarantor herein. The execution and delivery of any instrument adding
an additional Guarantor as a party to this Agreement shall not require the
consent of any Guarantor hereunder. The rights and obligations of each Guarantor
hereunder shall remain in full force and effect notwithstanding the addition of
any new Guarantor as a party to this Agreement.

     SECTION 20. Right of Setoff. If an Event of Default shall have occurred and
be continuing and the Administrative Agent shall have declared, or the Required
Lenders shall have requested the Administrative Agent to declare, the Loans
immediately due and payable pursuant to Article VII of the Loan Agreement, each
Lender is hereby authorized at any time and from time to time, to the fullest
extent permitted by law but in all cases, subject to the subordination
provisions of Article VIII of the Loan Agreement and Section 6(b) hereof, to set
off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other Indebtedness at any time owing
by such Lender or any Affiliate thereof to or for the credit or the account of
any Guarantor against any of and all the obligations of any Guarantor now or
hereafter existing under this Agreement and any other Loan Documents to which
such Guarantor is a party, held by such Lender, irrespective of whether or not
such Lender shall have made any demand under the Loan Agreement or any such
other Loan Document and although such obligations may be unmatured. The rights
of each Lender under this Section are in addition to other rights and remedies
(including other rights of setoff) that such Lender may have.

                                                         the Guarantor Agreement

                    SUPPLEMENT NO. ____ dated as of _______ to the Subordinated
                    Guarantee Agreement dated as of December 20, 1996, (as the
                    same may be amended, restated, supplemented, modified or
                    waived from time to time, the "Guarantee Agreement"),
                    between each Subsidiary listed on the signature pages
                    thereof (individually, a "Guarantor" and collectively, the
                    "Guarantors"); and SOCIETE GENERALE, as administrative agent
                    (the Administrative Agent") for the Lenders (as defined in
                    the Loan Agreement referred to below).

     A. Reference is made to the Senior Subordinated Loan Agreement dated as of
December 20, 1996 (as amended, restated, supplemented, modified or waived from
time to time, the "Loan Agreement"), among the Borrower, the financial
institutions party thereto (the "Lenders") and Societe Generale, as
administrative agent (in such capacity, the "Administrative Agent").

     B. Capitalized terms used herein and not otherwise defined herein shall
have the meanings assigned to such terms in the Guarantee Agreement and the Loan
Agreement.

     C. The Subsidiaries have entered into the Guarantee Agreement in order to
induce the Lenders to make Loans. Pursuant to Section 5.10 of the Loan
Agreement, each Subsidiary (other than any Foreign Subsidiary) that was not in
existence or not such a Subsidiary or was a subsidiary of the Company on the
date of the Loan Agreement is required to enter into the Guarantee Agreement as
a Guarantor upon becoming a Subsidiary. Section 19 of the Guarantee Agreement
provides that additional Subsidiaries may become Guarantors under the Guarantee
Agreement by execution and delivery of an instrument in the form of this
Supplement. The undersigned Subsidiary (the "New Guarantor") is executing this
Supplement in accordance with the requirements of the Loan Agreement to become a
Guarantor under the Guarantee Agreement as consideration for Loans previously
made.

     Accordingly, the Administrative Agent and the New Guarantor agree as
follows:

     SECTION 1. In accordance with Section 19 of the Guarantee Agreement, the
New Guarantor by its signature below becomes a Guarantor under the Guarantee
Agreement with the same force and effect as if originally named therein as a
Guarantor and the New Guarantor hereby agrees (a) to all the terms and
provisions of the Guarantor Agreement applicable to it as a Guarantor thereunder
and (b) represents and warrants that the representations and warranties made by
it as a Guarantor thereunder are true and correct on and as of the date hereof,
except to the
<PAGE>
 
                                                                               2

extent such representations and warranties speak as of an earlier date. Each
reference to a "Guarantor" in the Guarantee Agreement shall be deemed to include
the New Guarantor. The Guarantee Agreement, as supplemented hereby, is hereby
incorporated herein by reference.

     SECTION 2. The New Guarantor represents and warrants to the Administrative
Agent and the other Lenders that this Supplement has been duly authorized,
executed and delivered by it and constitutes its legal, valid and binding
obligation, enforceable against it in accordance with its terms, except as the
enforceability thereof may be limited by bankruptcy, insolvency, reorganization,
fraudulent transfer, moratorium or other similar laws affecting creditors'
rights generally and by general principles of equity (regardless of whether such
enforceability is considered in a proceeding at law or in equity).

     SECTION 3. This Supplement may be executed in two or more counterparts,
each of which shall constitute an original, but all of which, when taken
together, shall constitute but one instrument. This Supplement shall become
effective when the Administrative Agent shall have received counterparts of this
Supplement that, when taken together, bear the signatures of the New Guarantor
and the Administrative Agent.

     SECTION 4. The New Guarantor hereby represents and warrants that set forth
under its signature hereto is the true and correct location of the chief
executive office of the New Guarantor.

     SECTION 5. Except as expressly supplemented hereby, the Guarantee Agreement
shall remain in full force and effect.

     SECTION 6. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

     SECTION 7. In case any one or more of the provisions contained in this
Supplement should be held invalid, illegal or unenforceable in any respect,
neither party hereto shall be required to comply with such provision for so long
as such provision is held to be invalid, illegal or unenforceable, but the
validity, legality and enforceability of the remaining provisions contained
herein and in the Guarantee Agreement shall not in any way be affected or
impaired. The parties hereto shall endeavor in good-faith negotiations to
replace the invalid, illegal or unenforceable provisions with valid provisions
the economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

     SECTION 8. All communications and notices hereunder shall be in writing and
given as provided in Section 13 of the Guarantee Agreement. All

communications and notices hereunder to the New Guarantor shall be given to it
at the address set forth under its signature hereto, with a copy to the
Borrower.

     SECTION 9. The New Guarantor agrees to reimburse the Administrative Agent
for its reasonable out-of-pocket expenses in connection with this Supplement,
including the reasonable fees, other charges and disbursements of counsel for
the Administrative Agent.

     SECTION 10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER
OR IN CONNECTION WITH THIS AGREEMENT. EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK
TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER
PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     IN WITNESS WHEREOF, the New Guarantor and the Administrative Agent have
duly executed this Supplement to the Guarantee Agreement as of the day and year
first above written.

                                                           to the Loan Agreement

                         INDEMNITY, SUBROGATION AND CONTRIBUTION AGREEMENT dated
                    as of December 20, 1996, among SCHEIN PHARMACEUTICAL, INC.,
                    a Delaware corporation (the "Borrower"), each Subsidiary
                    from time to time party hereto (individually, a "Guarantor"
                    and collectively the "Guarantors"), and SOCIETE GENERALE, as
                    administrative agent (in such capacity, the "Administrative
                    Agent") for the Lenders (as defined in the Loan Agreement
                    referred to below).

     Reference is made to (a) the Loan Agreement dated as of December 20, 1996
(as amended, restated, supplemented, modified or waived from time to time, the
"Loan Agreement"), among the Borrower, the financial institutions party thereto
as lenders (the "Lenders") and Societe Generale, as administrative agent (in
such capacity, the "Administrative Agent") and (b) the Subordinated Guarantee
Agreement dated as of December 20, 1996 (as amended, restated, supplemented,
modified or waived from time to time, the "Guarantee Agreement") among the
Guarantors and the Administrative Agent.

     The Lenders have agreed to make Loans to the Borrower, pursuant to, and
upon the terms and subject to the conditions specified in, the Loan Agreement.
The Guarantors have guaranteed such Loans and the other Obligations pursuant to
the Guarantee Agreement (for purposes of this Agreement, the "Guarantees"). The
obligations of the Lenders to make Loans are conditioned on, among other things,
the execution and delivery by the Borrower and the Guarantors of an agreement in
the form hereof. Capitalized terms used herein and not defined herein shall have
the meanings assigned to such terms in the Loan Agreement.

     Accordingly, the Borrower, each Guarantor and the Administrative Agent
agree as follows:

     SECTION 1. Indemnity and Subrogation. In addition to all such rights of
indemnity and subrogation that the Guarantors may have under applicable law (but
subject to Section 3), the Borrower agrees that in the event a payment shall be
made by any Guarantor under the Guarantee Agreement, the Borrower shall
indemnify such Guarantor for the full amount of such payment and such Guarantor
shall be subrogated to the rights of the Person to whom such payment shall have
been made to the extent of such payment.

     SECTION 2. Contribution and Subrogation. Each Guarantor (a "Contributing
Guarantor") agrees (subject to Section 3) that, in the event a payment shall be
made by any other Guarantor under the Guarantee Agreement and such other
Guarantor (the "Claiming Guarantor") shall not have been indemnified by the
Borrower as provided in Section 1, the Contributing Guarantor shall indemnify
the
<PAGE>
 
                                                                               2

Claiming Guarantor in an amount equal to the amount of such payment multiplied
by a fraction of which the numerator shall be the net worth (without taking into
account any Obligations) of the Contributing Guarantor on the date hereof (or,
if later, the date such Contributing Guarantor became a party hereto) and the
denominator shall be the aggregate net worth (without taking into account any
Obligations) of all the Guarantors on the date hereof plus the net worth of any
Guarantor becoming a party hereto pursuant to Section 14 on the date such
Guarantor so became a party hereto. Any Contributing Guarantor making any
payment to a Claiming Guarantor pursuant to this Section 2 shall be subrogated
to the rights of such Claiming Guarantor under Section 1 to the extent of such
payment.

     SECTION 3. Subordination. Notwithstanding any provision of this Agreement
to the contrary, all rights of the Guarantors under Sections 1 and 2 and all
other rights of indemnity, contribution or subrogation under applicable law or
otherwise shall be fully subordinated to and shall not be exercised prior to the
indefeasible payment in full of the Obligations. No failure on the part of the
Borrower or any Guarantor to make the payments required by Sections 1 and 2 (or
any other payments required under applicable law or otherwise) shall in any
respect limit the obligations and liabilities of any Guarantor with respect to
any Guarantee, and each Guarantor shall remain liable for the full amount of the
obligations of such Guarantor under each such Guarantee.

     SECTION 4. Termination. This Agreement shall survive and be in full force
and effect so long as any Obligation is outstanding and has not been
indefeasibly paid in full in cash and shall continue to be effective or be
reinstated, as the case may be, if at any time payment, or any part thereof, of
any Obligation is rescinded or must otherwise be restored by any Lender or any
Guarantor upon the bankruptcy or reorganization of the Borrower, any Guarantor
or otherwise.

     SECTION 5. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

     SECTION 6. No Waiver. No failure on the part of the Administrative Agent or
any Guarantor to exercise, and no delay in exercising, any right, power or
remedy hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right, power or remedy by the Administrative Agent
or any Guarantor preclude any other or further exercise thereof or the exercise
of any other right, power or remedy. All remedies hereunder are cumulative and
are not exclusive of any other remedies provided by law. None of the
Administrative Agent and the Guarantors shall be deemed to have waived any
rights hereunder unless such waiver shall be in writing and signed by such
parties.

     SECTION 7. Notices. All communications and notices hereunder shall be in
writing and given as provided in Section 13 of the Guarantee Agreement and
addressed as specified in such Section 13.

     SECTION 8. Binding Agreement; Assignments etc. Whenever in this Agreement
any of the parties hereto is referred to, such reference shall be deemed to
include the successors and assigns of such party; and all covenants, promises
and agreements by or on behalf of the parties that are contained in this
Agreement shall bind and inure to the benefit of their respective successors and
assigns. Neither the Borrower nor any of the Guarantors may assign or transfer
any of its rights or obligations hereunder (and any such attempted assignment or
transfer shall be void) without the prior written consent of the Required
Lenders.

     SECTION 9. Survival of Agreement; Severability. (a) All covenants and
agreements made by the Borrower and each Guarantor herein and in the
certificates or other instruments prepared or delivered in connection with this
Agreement or the other Loan Documents shall be considered to have been relied
upon by the Administrative Agent, the other Lenders and each Guarantor and shall
survive the making by the Lenders of the Loans and shall continue in full force
and effect as long as the principal of or any accrued interest on any Loans or
any other fee or amount payable under the Loan Agreement or this Agreement or,
without duplication of the foregoing, under any of the other Loan Documents is
outstanding and unpaid and as long as the Commitments have not been terminated.

     (b) In case any one or more of the provisions contained in this Agreement
should be held invalid, illegal or unenforceable in any respect, no party hereto
shall be required to comply with such provision for so long as such provision is
held to be invalid, illegal or unenforceable, but the validity, legality and
enforceability of the remaining provisions contained herein shall not in any way
be affected or impaired thereby. The parties shall endeavor in good-faith
negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions the economic effect of which comes as close as possible to that
of the invalid, illegal or unenforceable provisions.

     SECTION 10. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall constitute an original, but all of which, when
taken together, shall constitute but one instrument. This Agreement shall be
effective with respect to any Guarantor when a counterpart bearing the signature
of such Guarantor shall have been delivered to and executed by the
Administrative Agent.

     SECTION 11. Rules of Interpretation. The rules of interpretation specified
in Section 1.2 of the Loan Agreement shall be applicable to this Agreement.

     SECTION 12. Jurisdiction; Consent to Service of Process. (a) The
Administrative Agent, the Borrower and each Guarantor hereby irrevocably and
unconditionally submits, for itself and its property, to the nonexclusive
jurisdiction of any New York State court or Federal court of the United States
of America sitting in New York City, and any appellate court from any thereof,
in any action or proceeding arising out of or relating to this Agreement, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such New York State or,
to the extent permitted by law, in such Federal court. Each of the parties
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Each of the parties hereto agrees that it
will not institute or seek to institute any action or proceeding arising out of
or relating to this Agreement (other than an action or proceeding seeking
enforcement of a judgment) in any forum other than a New York State court or
Federal court of the United States of America sitting in New York City.

     (b) The Administrative Agent, the Borrower and each Guarantor hereby
irrevocably and unconditionally waive, to the fullest extent it may legally and
effectively do so, any objection it may now or hereafter have to the laying of
venue of any suit, action or proceeding arising out of or relating to this
Agreement in any New York State or Federal court of the United States of America
sitting in New York. Each of the parties hereto hereby irrevocably waives, to
the fullest extent permitted by law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court.

     (c) Each party to this Agreement irrevocably consents to service of process
in the manner provided for notices in Section 7. Nothing in this Agreement will
affect the right of any party to this Agreement to serve process in any other
manner permitted by law.

     SECTION 13. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER
OR IN CONNECTION WITH THIS AGREEMENT. EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK
TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER
PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     SECTION 14. Additional Guarantors. Pursuant to Section 5.10 of the Loan
Agreement each Subsidiary (other than Foreign Subsidiaries) that was not in
existence or not such a Subsidiary on the date of the Loan Agreement is required
to enter into the Guarantee Agreement as a Guarantor upon becoming a Subsidiary.
Upon execution and delivery, after the date hereof, by the Administrative Agent
and such a Subsidiary of an instrument in the form of Annex 1, such Subsidiary
shall become a Guarantor hereunder with the same force and effect as if
originally named as a Guarantor hereunder. The execution and delivery of any
instrument adding an additional Guarantor as a party to this Agreement shall not
require the consent of any Guarantor hereunder or the Borrower. The rights and
obligations of each Guarantor hereunder shall remain in full force and effect
notwithstanding the addition of any new Guarantor as a party to this Agreement.

     SECTION 15. Amendment. Neither this Agreement nor any provision hereof may
be waived, amended or modified except pursuant to a written agreement entered
into between the Guarantor and the Administrative Agent, with the prior written
consent of the Required Lenders (except as otherwise provided in the Loan
Agreement).

                         SUPPLEMENT NO. ____ dated as of __________ to the
                    Indemnity, Subrogation and Contribution Agreement dated as
                    of December 20, 1996, (as the same may be amended, restated,
                    supplemented, modified or waived from time to time, the
                    "Indemnity, Subrogation and Contribution Agreement"), among
                    SCHEIN PHARMACEUTICAL, a Delaware corporation (the
                    "Borrower"); each Subsidiary listed on the signature pages
                    thereof (the "Guarantors"); and SOCIETE GENERALE, as
                    administrative agent (in such capacity, the "Administrative
                    Agent") for the Lenders (as defined in the Loan Agreement).

     A. Reference is made to the Senior Subordinated Loan Agreement dated as of
December 20, 1996 (as amended, restated, supplemented, modified or waived from
time to time, the "Loan Agreement"), among the Borrower, the financial
institutions party thereto (the "Lenders") and Societe Generale, as
administrative agent (in such capacity, the "Administrative Agent").

     B. Capitalized terms used herein and not otherwise defined herein shall
heave the meanings assigned to such terms in the Indemnity, Subrogation and
Contribution Agreement and the Loan Agreement.

     C. The Borrower and the Subsidiaries have entered into the Indemnity,
Subrogation and Contribution Agreement in order to induce the Lenders to make
Loans. Pursuant to Section 5.10 of the Loan Agreement, each Subsidiary (other
than any Foreign Subsidiary) that was not in existence or not such a Subsidiary
or was a subsidiary of the Company on the date of the Loan Agreement is required
to enter into the Indemnity, Subrogation and Contribution Agreement as a
Guarantor upon becoming a Subsidiary. Section 14 of the Indemnity, Subrogation
and Contribution Agreement provides that additional Subsidiaries may become
Guarantors under the Indemnity, Subrogation and Contribution Agreement by
execution and delivery of an instrument in the form of this Supplement. The
undersigned Subsidiary (the "New Guarantor") is executing this Supplement in
accordance with the requirements of the Loan Agreement to become a Guarantor
under the Indemnity, Subrogation and Contribution Agreement as consideration for
Loans previously made.

     Accordingly, the Administrative Agent and the New Guarantor agree as
follows:

     SECTION 1. In accordance with Section 14 of the Indemnity, Subrogation and
Contribution Agreement, the New Guarantor by its signature below becomes a
Guarantor under the Indemnity, Subrogation and Contribution Agreement with the
same force and effect as if originally named therein as a Guarantor and the

                                                                               2

New Guarantor hereby agrees (a) to all the terms and provisions of the
Indemnity, Subrogation and Contribution Agreement applicable to it as a
Guarantor thereunder and (b) represents and warrants that the representations
and warranties made by it as a Guarantor thereunder are true and correct on and
as of the date hereof, except to the extent such representations and warranties
speak as of an earlier date. Each reference to a "Guarantor" in the Indemnity,
Subrogation and Contribution Agreement shall be deemed to include the New
Guarantor. The Indemnity, Subrogation and Contribution Agreement, as
supplemented hereby, is hereby incorporated herein by reference.

     SECTION 2. The New Guarantor represents and warrants to the Administrative
Agent and the other Lenders that this Supplement has been duly authorized,
executed and delivered by it and constitutes its legal, valid and binding
obligation, enforceable against it in accordance with its terms, except as the
enforceability thereof may be limited by bankruptcy, insolvency, reorganization,
fraudulent transfer, moratorium or other similar laws affecting creditors'
rights generally and by general principles of equity (regardless of whether such
enforceability is considered in a proceeding at law or in equity).

     SECTION 3. This Supplement may be executed in two or more counterparts,
each of which shall constitute an original, but all of which, when taken
together, shall constitute but one instrument. This Supplement shall become
effective when the Administrative Agent shall have received counterparts of this
Supplement that, when taken together, bear the signatures of the New Guarantor
and the Administrative Agent.

     SECTION 4. The New Guarantor hereby represents and warrants that set forth
under its signature hereto is the true and correct location of the chief
executive office of the New Guarantor.

     SECTION 5. Except as expressly supplemented hereby, the Indemnity,
Subrogation and Contribution Agreement shall remain in full force and effect.

     SECTION 6. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

     SECTION 7. In case any one or more of the provisions contained in this
Supplement should be held invalid, illegal or unenforceable in any respect,
neither party hereto shall be required to comply with such provision for so long
as such provision is held to be invalid, illegal or unenforceable, but the
validity, legality and enforceability of the remaining provisions contained
herein and in the Indemnity, Subrogation and Contribution Agreement shall not in
any way be affected or impaired. The parties hereto shall endeavor in good-faith
negotiations to replace the invalid,

illegal or unenforceable provisions with valid provisions the economic effect of
which comes as close as possible to that of the invalid, illegal or
unenforceable provisions.

     SECTION 8. All communications and notices hereunder shall be in writing and
given as provided in Section 7 of the Indemnity, Subrogation and Contribution
Agreement. All communications and notices hereunder to the New Guarantor shall
be given to it at the address set forth under its signature hereto, with a copy
to the Borrower.

     SECTION 9. The New Guarantor agrees to reimburse the Administrative Agent
for its reasonable out-of-pocket expenses in connection with this Supplement,
including the reasonable fees, other charges and disbursements of counsel for
the Administrative Agent.

     SECTION 10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER
OR IN CONNECTION WITH THIS AGREEMENT. EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK
TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER
PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     IN WITNESS WHEREOF, the New Guarantor and the Administrative Agent have
duly executed this Supplement to the Indemnity, Subrogation and Contribution
Agreement as of the day and year first above written.

                                                           to the Loan Agreement

                                                  December __, 1996

To Societe Generale, as Administrative Agent

To the Lenders under the Loan Agreement
referred to below

Ladies and Gentlemen:

     We have acted as special New York counsel to Schein Pharmaceutical, Inc., a
Delaware corporation (the "Borrower"), and the subsidiaries of the Borrower
listed on Annex 1 attached hereto (the "Subsidiaries" and, together with the
Borrower, the "Obligors") in connection with the preparation, execution and
delivery of the Senior Subordinated Loan Agreement dated as of December ___,
1996 (the "Loan Agreement") among the Borrower, the Lenders from time to time
party thereto, and Societe Generale as administrative agent (in such capacity,
the "Administrative Agent"), providing for, among other things, the making of
loans by the Lenders in an aggregate principal amount of $100,000,000. This
opinion is being delivered to you at the request of the Obligors pursuant to
Section 4.2 of the Loan Agreement. All capitalized terms used but not defined in
this opinion have the respective meanings given them in the Loan Agreement.

     For purposes of this opinion, we have examined the following documents each
dated the date hereof (collectively the "Loan Documents"):

     (a)  the Loan Agreement;

     (b)  the Guarantee Agreement;

     (c)  the Conversion Note Registration Rights Agreement; and
<PAGE>
 
     (d)  the Indemnity, Subrogation and Contribution Agreement.

     In giving this opinion, we have assumed, with your permission, the
genuineness of all signatures, the legal capacity of natural persons and the
authenticity of all documents we have examined. As to questions of fact relevant
to this opinion, with your permission and without any independent investigation
or verification, we have relied upon, and assumed the accuracy of, the
representations and warranties of each party in the Loan Documents and have
relied upon certificates of officers of the Obligors (each a "Fact Certificate")
and written statements of certain public officials. We also have assumed, with
your permission and without any independent verification, compliance by each
party to the Loan Documents with its agreements in the respective Loan
Documents, and that each Loan Document constitutes the legal, valid and binding
obligation of each party to it (other than the Obligors) and is enforceable
against each such party in accordance with its terms. In addition, we have
assumed, with your permission and without any independent verification, that:

          (i) the execution, delivery and performance of each of its obligations
     under the Loan Documents does not and will not conflict with, violate,
     breach or constitute a default under, or require any consent under, (A) any
     law, rule or regulation to which the Obligors are subject (other than those
     as to which we express our opinion in paragraph 6(a) below), (B) any order,
     writ, injunction or decree of any court or governmental authority or any
     arbitral award (other than those as to which we express our opinion in
     paragraph 6(b) below) or (C) any agreement or instrument to which the
     Obligors or their properties are subject (other than those as to which we
     express our opinion in paragraph 6(c) below); and

          (ii) no approval, authorization or other action by, or filing with,
     any court or governmental authority (other than those as to which we
     express our opinion in paragraph 7 below) is required to authorize or is
     required in connection with the execution, delivery or performance by the
     Obligors of the Loan Documents or the transactions contemplated by the Loan
     Documents.

     Based upon and subject to the foregoing and the comments and qualifications
set forth below, we are of the opinion that:


                                        2
<PAGE>
 
actual knowledge of any actions, suits or proceedings at law or in equity or by
or before any Governmental Authority now pending or threatened against or
affecting any of the Obligors or any business, property or rights of any such
person (a) that involve any Loan Documents or (b) as to which there is a
likelihood of an adverse determination and that, if adversely determined, could
reasonably be expected, individually or in the aggregate, to result in a
Material Adverse Effect.

     9. Neither the Borrower nor any Subsidiary is an "investment company" or a
company "controlled" by an "investment company" within the meaning of the
Investment Company Act of 1940, as amended.

     10. Neither the Borrower nor any Subsidiary is a "holding company" within
the meaning of the Public Utility Holding Company Act of 1935, as amended.

     The opinions expressed herein are subject to the following qualifications
and comments:

     (a) The enforceability of each Loan Document against each Obligor that is a
party to it may be limited by bankruptcy, insolvency, fraudulent conveyance,
fraudulent transfer, reorganization, moratorium and other similar laws relating
to or affecting creditors' rights generally and by general equitable principles
(regardless of whether enforcement is sought in equity or at law), including,
without limitation, principles regarding good faith and fair dealing. In
addition, we express no opinion as to the enforceability of (i) provisions that
purport to establish evidentiary standards, (ii) provisions exculpating a party
from, or indemnifying a party for (or entitling a party to contribution in a
case involving), its own gross negligence, willful misconduct or violation of
securities or other laws, (iii) provisions relating to the availability of
specific remedies or relief, or the release or waiver of any remedies or rights
or time periods in which claims are required to be asserted, (iv) provisions
that allow cumulative remedies or (v) provisions relating to the discharge of
defenses or disclaimers, liability limitations or limitations of the obligations
of any Lender or the Administrative Agent or an Obligor under any of the Loan
Documents.

     (b) Insofar as the opinion in paragraph 5 relates to the Guarantee
Agreement, we have with your permission assumed the adequacy of the
consideration that supports the Guarantee Agreement and the solvency and
adequacy of capital of each of the Subsidiaries.

authenticated and delivered by the Trustee or disposed of by the Company, such
Security nevertheless may be authenticated and delivered or disposed of as

          Each Security shall be dated the date of its authentication, shall
bear interest from the applicable date, and shall be payable on the dates
specified on the face of the form of Security recited above.

          The Person in whose name any Security is registered at the close of
business on any record date with respect to any interest payment date shall be
entitled to receive the interest, if any, payable on such interest payment date
notwithstanding any transfer or exchange of such Security subsequent to the
record date and prior to such interest payment date, except if and to the extent
that the Company shall default in the payment of the interest due on such
interest payment date, in which case such defaulted interest shall be paid to
the Persons in whose names outstanding Securities are registered at the close of
business on a subsequent record date (which shall be not less than five business
days prior to the date of payment of such defaulted interest) established by
notice given by mail by or on behalf of the Company to the holders of Securities
not less than 15 days preceding such subsequent record date.  The term "record

payment of defaulted interest) shall mean if such interest payment date is the
first day of a calendar month, the fifteenth day of the next preceding calendar
month and shall mean, if such interest payment date is the fifteenth day of a
calendar month, the last day of the next preceding calendar month, whether or
not such record date is a business day.

definitive, fully registered form without interest coupons with the Global
Securities Legend and Restricted Securities Legend set forth in the form of
Initial Notes (the "Restricted Global Security") deposited with the Trustee, at
the Corporate Trust Office, as custodian for and registered in the name of the
Depository or a nominee of the Depository, duly executed by the Company and
authenticated by the Trustee as hereinafter provided.  The aggregate principal
amount of the Restricted Global Security may from time to time be increased or
decreased by adjustments made on the records of the Trustee and the Depository
or its nominee as hereinafter provided.

          (c)  This Section 2.4(c) shall apply only to the Restricted Global
Security deposited with or on behalf of the Depository.

          Members of, or participants in, the Depository (the "Agent Members")
shall have no rights under this Indenture with respect to any Restricted Global
Security held on their behalf by the Depository or under the Restricted Global
Security, and the Depository may be treated by the Company, the Trustee, and any
agent of the Company or the Trustee as the absolute owner of the Restricted
Global Security for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by the Depository or impair, as between the
Depository and its Agent Members, the operation of customary practices governing
the exercise of the rights of a holder of any Security.

          (d)  Except as provided in this Section 2.4(d) and Section 2.8, owners
of beneficial interests in the Restricted Global Security will not be entitled
to receive physical delivery of certificated Initial Notes.  Purchasers of
Initial Notes who are not QIBs or QIBs who elect to receive certificated Initial
Notes instead of holding their interest through the Restricted Global Security
(collectively, the "Non-Global Purchasers") will receive certificated Initial
Notes bearing the Restricted Securities Legend (the "Restricted Securities");
provided, however, that upon transfer to a QIB of any such certificated Initial

Notes initially issued to a Non-Global Purchaser, such certificated Initial
Notes will, unless the transferee requests otherwise or the Restricted Global
Security has previously been exchanged in whole for Restricted Securities, be
exchanged for an interest in the Restricted Global Security pursuant to the
provisions of Section 2.5.  Restricted Securities will bear the Restricted
Securities Legend unless removed in accordance with Section 2.5.

          Upon the occurrence of an Effective Registration involving a Notes
Shelf Registration, all requirements with respect to the Restricted Global
Security and legends on Initial Notes will cease to apply, and certificated
Initial Notes without the Restricted Securities Legend will be available to the
Holders.  Upon the occurrence of an Effective Registration involving the
Registered Exchange Offer, all requirements with respect to the Restricted
Global Security will cease to apply and certificated Initial Notes with the
"Restricted Securities Legend" will be available to Holders that do not exchange
their Initial Notes for Exchange Notes, and certificated Exchange Notes without
any legends will be available to Holders that exchange their Initial Notes for
Exchange Notes.

          All certificated Securities shall be issuable in denominations of
$1,000 principal amount and any integral multiple thereof.

          SECTION 2.5  Registration, Transfer and Exchange.  (a) The Company
                       -----------------------------------                  
will keep at each office or agency to be maintained for the purpose as provided
in Section 3.2 a register or registers in which, subject to such reasonable
regulations as it may prescribe, it will register, and will register the
transfer of, Securities as in this Article provided.  Such register shall be in
written form in the English language or in any other form capable of being
converted into such form within a reasonable time.  At all reasonable times such
register or registers shall be open for inspection by the Trustee.

          Upon due presentation for registration of transfer of any Security at
each such office or agency, the Company shall execute and the Trustee shall
authenticate and deliver in the name of the transferee or transferees a new
Security or Securities in authorized denominations for a like aggregate
principal amount.

          Any Security or Securities may be exchanged for a Security or
Securities in other authorized denominations, in an equal aggregate principal
amount.  Securities to be exchanged shall be surrendered at each office or
agency to be maintained by the Company for the purpose as provided in Section
3.2, and the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor the Security or Securities which the Securityholder
making the exchange shall be entitled to receive, bearing numbers not
contemporaneously outstanding.

                                                                              20

          All Securities presented for registration of transfer, exchange,
redemption or payment shall (if so required by the Company or the Trustee) be
duly endorsed by, or be accompanied by a written instrument or instruments of
transfer in form satisfactory to the Company and the Trustee duly executed by,
the holder or his attorney duly authorized in writing.

          The Company may require payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in connection with any exchange
or registration of transfer of Securities.  No service charge shall be made for
any such transaction.

          The Trustee shall not be required to exchange or register a transfer
of (a) any Securities for a period of 15 days next preceding the mailing of
notice of redemption of Securities to be redeemed and ending on the date of such
mailing or (b) any Securities selected, called or being called for redemption
except, in the case of any Security where public notice has been given that such
Security is to be redeemed in part, the portion thereof not so to be redeemed.

          All Securities issued upon any transfer or exchange of Securities
shall be valid obligations of the Company, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Securities
surrendered upon such transfer or exchange.

          (b)  Notwithstanding any provision to the contrary herein, so long as
the Restricted Global Security remains outstanding and is held by or on behalf
of the Depository, transfers of the Restricted Global Security, in whole or in
part, shall only be made in accordance with Section 2.4(d) and this Section 2.5
as set forth below.

               (i) Subject to clauses (ii) through (iv) below, transfers of the
     Restricted Global Security shall be limited to transfers of the Restricted
     Global Security in whole, but not in part, to nominees of the Depository or
     to a successor of the Depository or such successor's nominee.

               (ii) Restricted Global Security to Restricted Security. If a
                    -------------------------------------------------      
     holder of a beneficial interest in the Restricted Global Security deposited
     with the Depository wishes at any time to transfer its interest therein to
     a Person who wishes to take delivery thereof in the form of a Restricted
     Security, such holder may, subject to the rules and procedures of the
     Depository, cause the exchange of such interest for one or more Restricted
     Securities of any authorized denomination or denominations and of the same
     aggregate principal amount.  Upon receipt by the Trustee at its Corporate
     Trust Office of (1) instructions from the Depository directing the Trustee
     to authenticate and deliver one or more Restricted Securities of the same
     aggregate principal amount as the beneficial interest in the Restricted
     Global Security to be exchanged, such instructions to contain the name or
     names of the designated transferee or transferees, the authorized
     denomination or denominations of the Restricted Securities to be so issued
     and appropriate delivery instructions, (2) a certificate in the form of
     Exhibit C attached hereto given by the holder of such beneficial interest
     and stating that the 
<PAGE>
 
                                                                              21

     Person transferring such interest in the Restricted Global Security
     reasonably believes that the Person acquiring the Restricted Securities for
     which such interest is being exchanged is an Institutional Accredited
     Investor and is acquiring such Restricted Securities for its own account or
     for one or more accounts as to which the transferee exercises sole
     investment discretion, (3) a certificate in the form of Exhibit D attached
     hereto given by the Person acquiring the Restricted Securities for which
     such interest is being exchanged, to the effect set forth therein, and (4)
     an opinion of counsel to the holder of such beneficial interest in the form
     of Exhibit E attached hereto, to the effect set forth therein, then the
     Trustee will instruct the Depository to reduce the Restricted Global
     Security by the aggregate principal amount of the beneficial interest
     therein to be exchanged, and concurrently with such reduction the Company
     shall execute, and the Trustee shall authenticate and deliver, one or more
     Restricted Securities of the same aggregate principal amount, in accordance
     with the instructions referred to above.

               (iii)      Restricted Security to Restricted Global Security.  If
                          -------------------------------------------------     
     a holder of a Restricted Security wishes at any time to transfer such
     Restricted Security to a Person who wishes to take delivery thereof in the
     form of an interest in the Restricted Global Security, such holder may,
     subject to the rules and procedures of the Depository, cause the exchange
     of such Restricted Security for an equivalent beneficial interest in the
     Restricted Global Security.  Upon receipt by the Trustee at its Corporate
     Trust Office of (1) such Restricted Security, duly endorsed as provided
     herein, (2) instructions from such holder directing the Trustee to credit
     or cause to be credited a beneficial interest in the Restricted Global
     Security equal to the principal amount of the Restricted Security to be
     exchanged, such instructions to contain information regarding the
     participant account with the Depository to be credited with such interest,
     and (3) a certificate in the form of Exhibit F attached hereto, then the
     Trustee shall cancel or cause to be cancelled such Restricted Security and
     shall instruct the Depository to credit or cause to be credited to the
     account of the Person specified in such instructions a beneficial interest
     in the Restricted Global Security equal to the principal amount of the
     Restricted Security so cancelled.

               (iv) Restricted Security to Restricted Security.  If a holder of
                    ------------------------------------------                 
     a Restricted Security wishes at any time to transfer such Restricted
     Security to a Person who wishes to take delivery thereof in the form of a
     Restricted Security, such holder may, subject to the restrictions on
     transfer set forth herein and in such Restricted Security, cause the
     exchange of such Restricted Securities for one or more Restricted
     Securities of any authorized denomination or denominations and of the same
     aggregate principal amount.  Upon receipt by the Trustee at its Corporate
     Trust Office of (1) such Restricted Security, duly endorsed as provided
     herein, (2) instructions from such holder directing the Trustee to
     authenticate and deliver one or more Restricted Securities of the same
     aggregate principal amount as the Restricted Security to be exchanged, such
     instructions to contain the name or names of the designated transferee or
     transferees, the authorized denomination or denominations of the Restricted
     Securities to be so issued and appropriate delivery instructions, (3) a
     certificate from the holder of the Restricted Security to be exchanged in
     the form of Exhibit C attached hereto (in the event that the transfer is 
     being made to an Institutional Accredited 
<PAGE>
 
                                                                              22


     Investor otherwise than pursuant to Rule 144A), (4) a certificate in the
     form of Exhibit D attached hereto (in the event the transfer is being made
     to an Institutional Accredited Investor otherwise than pursuant to Rule
     144A) given by the Person acquiring the Restricted Securities for which
     such interest is being exchanged, to the effect set forth therein, and (5)
     an opinion of counsel to the transferor of such Restricted Security in the
     form of Exhibit E hereto, to the effect set forth therein, then the Trustee
     shall cancel or cause to be cancelled such Restricted Security and,
     concurrently therewith, the Company shall execute, and the Trustee shall
     authenticate and deliver, one or more Restricted Securities of the same
     aggregate principal amount, in accordance with the instructions referred to
     above.

               (v) Other Exchanges.  In the event that the Restricted Global
                   ---------------                                          
     Security is exchanged pursuant to Section 2.8 for Securities in definitive
     registered form without interest coupons, prior to an Effective
     Registration such Initial Notes may be exchanged for one another only in
     accordance with those procedures that are substantially consistent with the
     provisions of clauses (i) through (iv) above (including the certification
     requirements thereof intended to insure that such transfers comply with the
     Securities Act) and which may be from time to time adopted by the Company
     and the Trustee.

          If Initial Notes are issued upon the transfer, exchange or replacement
of Initial Notes bearing the Restricted Securities Legend, or if a request is
made to remove such Restricted Securities Legend on Initial Notes, the Initial
Notes so issued shall bear the Restricted Securities Legend, or the Restricted
Securities Legend shall not be removed, as the case may be, unless (i) there is
delivered to the Company such satisfactory evidence, which may include an
opinion of counsel licensed to practice law in the State of New York, as may be
reasonably required by the Company that neither the legend nor the restrictions
on transfer set forth therein are required to ensure that transfers thereof
comply with the provisions of the Securities Act or, with respect to Restricted
Securities, that such Initial Notes are not "restricted" within the meaning of
Rule 144 under the Securities Act or (ii) there is an Effective Registration
involving the Notes Shelf Registration with respect to the Initial Notes then in
effect or the Initial Note as to which the Restricted Securities Legend is
sought to be removed has been disposed of in accordance with the Notes Shelf
Registration.  Upon (i) provision of such satisfactory evidence or (ii)
notification by the Company to the Trustee of an Effective Registration with
respect to the Initial Notes, the Trustee, at the direction of the Company,
shall authenticate and deliver Initial Notes that do not bear the Restricted
Securities Legend.

          SECTION 2.6  Mutilated, Defaced, Destroyed, Lost and Stolen
                       ----------------------------------------------
Securities.  In case any temporary or definitive Security shall become
mutilated, defaced or be apparently destroyed, lost or stolen, the Company in
its discretion may execute, and upon the written request of any officer of the
Company, the Trustee shall authenticate and deliver, a new Security, bearing a
number not contemporaneously outstanding, in exchange and substitution for the
mutilated or defaced Security, or in lieu of and substitution for the Security
so apparently destroyed, lost or stolen.  In every case the applicant for a
substitute Security shall furnish to the Company and to the Trustee and any
agent of the Company or the Trustee such
<PAGE>
 
                                                                              23

security or indemnity as may be required by them to indemnify and defend and to
save each of them harmless and, in every case of destruction, loss or theft
evidence to their satisfaction of the apparent destruction, loss or theft of
such Security and of the ownership thereof.

          Upon the issuance of any substitute Security, the Company may require
the payment of a sum sufficient to cover any tax or other governmental charge
that may be imposed in relation thereto and any other expenses (including the
fees and expenses of the Trustee) connected therewith.  In case any Security
which has matured or is about to mature, or has been called for redemption in
full, shall become mutilated or defaced or be apparently destroyed, lost or
stolen, the Company may, instead of issuing a substitute Security, pay or
authorize the payment of the same (without surrender thereof except in the case
of a mutilated or defaced Security), if the applicant for such payment shall
furnish to the Company and to the Trustee and any agent of the Company or the
Trustee such security or indemnity as any of them may require to save each of
them harmless from all risks, however remote, and, in every case of apparent
destruction, loss or theft, the applicant shall also furnish to the Company and
the Trustee and any agent of the Company or the Trustee evidence to their
satisfaction of the apparent destruction, loss or theft of such Security and of
the ownership thereof.

          Every substitute Security issued pursuant to the provisions of this
Section by virtue of the fact that any Security is apparently destroyed, lost or
stolen shall constitute an additional contractual obligation of the Company,
whether or not the apparently destroyed, lost or stolen Security shall be at any
time enforceable by anyone and shall be entitled to all the benefits of (but
shall be subject to all the limitations of rights set forth in) this Indenture
equally and proportionately with any and all other Securities duly authenticated
and delivered hereunder.  All Securities shall be held and owned upon the
express condition that, to the extent permitted by law, the foregoing provisions
are exclusive with respect to the replacement or payment of mutilated, defaced,
or apparently destroyed, lost or stolen Securities and shall preclude any and
all other rights or remedies notwithstanding any law or statute existing or
hereafter enacted to the contrary with respect to the replacement or payment of
negotiable instruments or other securities without their surrender.

          SECTION 2.7  Cancellation of Securities; Destruction Thereof.  All
                       -----------------------------------------------      
Securities surrendered for payment, redemption, registration of transfer or
exchange, if surrendered to the Company or any agent of the Company or the
Trustee, shall be delivered to the Trustee for cancellation or, if surrendered
to the Trustee, shall be cancelled by it; and no Securities shall be issued in
lieu thereof except as expressly permitted by any of the provisions of this
Indenture.  The Trustee shall deliver cancelled Securities held by it to the
Company.  If the Company shall acquire any of the Securities, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Securities unless and until the same are delivered to the
Trustee for cancellation.

          SECTION 2.8  Temporary Securities; Global Securities.  Pending the
                       ---------------------------------------              
preparation of definitive Securities, the Company may execute and the Trustee
shall authenticate and deliver temporary Securities (printed, lithographed,
typewritten or otherwise reproduced, in each case in form satisfactory to the
Trustee). Temporary Securities shall be issuable as registered Securities
without coupons, of any authorized denomination, and
<PAGE>
 
                                                                              24

substantially in the form of the definitive Securities but with such omissions,
insertions and variations as may be appropriate for temporary Securities, all as
may be determined by the Company with the concurrence of the Trustee. Temporary
Securities may contain such reference to any provisions of this Indenture as may
be appropriate. Every temporary Security shall be executed by the Company and be
authenticated by the Trustee upon the same conditions and in substantially the
same manner, and with like effect, as the definitive Securities. Without
unreasonable delay, the Company shall execute and shall furnish definitive
Securities and thereupon temporary Securities may be surrendered in exchange
therefor without charge at each office or agency to be maintained by the Company
for the purpose pursuant to Section 3.2, and the Trustee shall authenticate and
deliver in exchange for such temporary Securities a like aggregate principal
amount of definitive Securities of authorized denominations. Until so exchanged
the temporary Securities shall be entitled to the same benefits under this
Indenture as definitive Securities.

          The Restricted Global Security deposited with the Depository pursuant
to Section 2.4 shall be transferred to the beneficial owners thereof only if
such transfer complies with Section 2.5(b) of this Indenture and (i) the
Depository notifies the Company that it is unwilling or unable to continue as
Depository for the Restricted Global Security or if at any time such Depository
ceases to be a "clearing agency" registered under the Exchange Act and a
successor depositary is not appointed by the Company within 90 days of such
notice, (ii) the Company executes and delivers to the Trustee an Officers'
Certificate stating that such Global Restricted Security shall be exchangeable,
or (iii) an Event of Default has occurred and is continuing with respect to the
Securities.

          Any Restricted Global Security that is transferable to the beneficial
owners thereof pursuant to this Section 2.8 shall be surrendered by the
Depository to the Trustee at its Corporate Trust Office, to be so transferred,
in whole or from time to time in part, without charge, and the Trustee shall
authenticate and deliver, upon such transfer of each portion of such Restricted
Global Security, an equal aggregate principal amount of Restricted Securities of
authorized denominations.  Any portion of the Restricted Global Security
transferred pursuant to this Section 2.8 shall be executed, authenticated and
delivered only in denominations of $1,000 and any integral multiple thereof and
registered in such names as the Depository shall direct.  Any Initial Note
delivered in exchange for an interest in the Restricted Global Security shall,
except as otherwise provided by Section 2.5, bear the Restricted Securities
Legend.

          Subject to the foregoing provisions of this Section 2.8, the
registered Holder of a Global Security may grant proxies and otherwise authorize
any Person, including Agent Members and Persons that may hold interests through
Agent Members, to take any action which a Holder is entitled to take under this
Indenture or the Securities.

          In the event of the occurrence of either of the events specified in
the second paragraph of this Section 2.8, the Company will promptly make
available to the Trustee a reasonable supply of certificated Securities in
definitive, fully registered form without interest coupons.

                                                                              25

          SECTION 2.9  Effective Registration.  In the event the Company has an
                       ----------------------                                  
Effective Registration, the Company shall notify the Trustee thereof in writing
within two Business Days after the effective date of such Effective
Registration.  If the Effective Registration involves a Notes Shelf
Registration, the Company shall promptly cause to be delivered to the Trustee
certificates for Initial Notes without legends and instructions to the Trustee
to authenticate and deliver certificated Initial Notes without legends to
Holders presenting their certificated Initial Notes for exchange or to Holders
of interests in the Restricted Global Security in the names and denominations
specified by the Depository or to transferees of Initial Notes covered by the
Notes Shelf Registration.  If the Effective Registration is with respect to a
Registered Exchange Offer for the Initial Notes, the Trustee shall notify the
Holders of receipt of such notice and, after receipt of a written order of the
Company (signed as specified in Section 2.1) for the authentication and delivery
of Exchange Notes and a properly completed letter of transmittal, ATOP
notification or other requested documents from a Holder as specified in the
exchange offer documents, shall exchange such Holder's Initial Notes for
Exchange Notes upon the terms set forth in the exchange offer documents.

          SECTION 2.10  CUSIP Numbers.  The Company in issuing the Securities
                        -------------                                        
may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee
shall use "CUSIP" numbers in notices of redemption as a convenience to Holders;
provided that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Securities or as contained
in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption shall
not be affected by any defect in or omission of such numbers.  The Company will
promptly notify the Trustee of any change in the "CUSIP" numbers.

                                  ARTICLE III

                            COVENANTS OF THE COMPANY
                            ------------------------

          SECTION 3.1  Payment of Principal and Interest.  The Company covenants
                       ---------------------------------                        
and agrees that it will duly and punctually pay or cause to be paid the
principal of, and interest on, each of the Securities at the place or places, at
the respective times and in the manner provided in the Securities.  Each
installment of interest on the Securities may be paid by mailing checks for such
interest payable to or upon the written order of the holders of Securities
entitled thereto as they shall appear on the registry books of the Company.

          SECTION 3.2  Offices for Payments, etc.  So long as any of the
                       -------------------------                        
Securities remain outstanding, the Company will maintain in the City of New York
the following:  (a) an office or agency where the Securities may be presented
for payment, (b) an office or agency where the Securities may be presented for
registration of transfer and for exchange as in this Indenture provided and (c)
an office or agency where notices and demands to or upon the Company in respect
of the Securities or of this Indenture may be served. The Company will give to
the Trustee written notice of the location of any such office or agency and of
any change of location thereof. The Company hereby initially designates the
Corporate Trust Office of the Trustee or such other location as the Company may
designate upon notice from 
<PAGE>
 
                                                                              26

the Trustee, as the office or agency for each such purpose. In case the Company
shall fail to maintain any such office or agency or shall fail to give such
notice of the location or of any change in the location thereof, presentations
and demands may be made and notices may be served at the Corporate Trust Office.

          SECTION 3.3  Appointment to Fill a Vacancy in Office of Trustee.  The
                       --------------------------------------------------      
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 5.9, a Trustee, so that there
shall at all times be a Trustee hereunder.

          SECTION 3.4  Paying Agents.  The paying agent will initially be the
                       -------------                                         
Trustee.  Whenever the Company shall appoint a paying agent other than the
Trustee, it will cause such paying agent to execute and deliver to the Trustee
an instrument in which such agent shall agree with the Trustee, subject to the
provisions of this Section:

          (a)  that it will hold all sums received by it as such agent for the
     payment of the principal of or interest on the Securities (whether such
     sums have been paid to it by the Company or by any other obligor on the
     Securities) in trust for the benefit of the holders of the Securities or of
     the Trustee,

          (b)  that it will give the Trustee notice of any  failure by the
     Company (or by any other obligor on the Securities) to make any payment of
     the principal of or interest on the Securities when the same shall be due
     and payable, and

          (c)  that it will pay any such sums so held in trust by it to the
     Trustee upon the Trustee's written request at any time during the
     continuance of the failure referred to in clause (b) above.

          The Company will, prior to each due date of the principal of or
interest on the Securities, deposit with the paying agent a sum sufficient to
pay such principal or interest, and (unless such paying agent is the Trustee)
the Company will promptly notify the Trustee of any failure to take such action.

          If the Company shall act as its own paying agent, it will, on or
before each due date of the principal of or interest on the Securities, set
aside, segregate and hold in trust for the benefit of the holders of the
Securities a sum sufficient to pay such principal or interest so becoming due.
The Company will promptly notify the Trustee of any failure to take such action.

          Anything in this Section to the contrary notwithstanding, the Company
may at any time, for the purpose of obtaining a satisfaction and discharge of
this Indenture or for any other reason, pay or cause to be paid to the Trustee
all sums held in trust by the Company or any paying agent hereunder, as required
by this Section, such sums to be held by the Trustee upon the trusts herein
contained.  Upon such payment to the Trustee, the relevant paying agent, if any,
shall be released from any liability with respect to such sums.

                                                                              27

          Anything in this Section to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section are subject to the
provisions of Sections 9.4 and 9.6.

          SECTION 3.5  Certificate to Trustee.  The Company will furnish to the
                       ----------------------                                  
Trustee, on or before 120 days after the end of each fiscal year of the Company
ending after the date hereof, an Officers' Certificate from the principal
executive, financial or accounting officer of the Company as to his or her
knowledge of the Company's compliance with all conditions and covenants under
this Indenture (such compliance to be determined without regard to any period of
grace or requirement of notice provided under this Indenture).

          SECTION 3.6  Securityholders' Lists.  If and so long as the Trustee
                       ----------------------                                
shall not be the Security registrar, the Company will furnish or cause to be
furnished to the Trustee a list in such form as the Trustee may reasonably
require of the names and addresses of the holders of the Securities pursuant to
Section 312 of the Trust Indenture Act (a) quarterly not more than 15 days after
each record date for the payment of quarterly interest on the Securities, as
hereinabove specified, as of such record date and (b) at such other times as the
Trustee may request in writing, within 30 days after receipt by the Company of

                        --------------------------------------------------   
The Company shall not, and shall not permit any Restricted Subsidiary to, make
any Asset Disposition unless (i) the Company or such Restricted Subsidiary
receives consideration (including by way of relief from, or by any other Person
assuming sole responsibility for, any liabilities, contingent or otherwise) at
the time of such Asset Disposition at least equal to the Fair Market Value of
the shares or assets that are the subject matter of such Asset Disposition, (ii)
at least 80% of the consideration therefor received by the Company or such
Restricted Subsidiary is in the form of cash; and (iii) an amount equal to 100%
of the Net Available Cash from such Asset Disposition is applied by the Company
(or such Restricted Subsidiary, as the case may be) (A) first, to the extent the

Company elects, to secure letter of credit obligations to the extent such
related letters of credit have not been drawn upon or returned undrawn; (C)
third, to the extent of the balance of Net Available Cash after application in
- -----
accordance with clauses (A) and (B), to the extent the Company or such
Restricted Subsidiary elects, within one year from the later of the date of such
Asset Disposition or the receipt of such Net Available Cash, to reinvest in
Additional Assets; and (D) fourth, to the extent of the balance of such Net
                           ------     
Available Cash after application in accordance with clauses (A), (B) and (C), to
make an offer (the "Offer") to purchase Securities pursuant and subject to the
conditions of this Indenture to the holders of the Securities at a purchase
price of 100% of the principal amount thereof plus accrued and unpaid interest
to the purchase date; provided, however, that, in connection with any
                      --------  -------  
prepayment, repayment or purchase of Indebtedness pursuant to clause (A) or (B)
above, the Company or such Restricted Subsidiary shall retire such Indebtedness
and shall cause the related loan commitment (if any) to be permanently reduced
in an amount equal to the principal amount so prepaid, repaid or purchased. The
Company shall not be required to make an offer for Securities pursuant to this
Section 3.10 if the Net Available Cash available therefor (after application of
the proceeds as provided in clauses (A), (B) and (C)) is less than $15,000,000
(which lesser amount shall be carried forward for purposes of determining
whether an offer is required with respect to the Net Available Cash from any
subsequent Asset Disposition).

          For the purposes of Section 3.10(a)(ii), the following will be deemed
to be cash:  (x) the assumption of Indebtedness (other than Disqualified Capital
Stock) of the Company or any Restricted Subsidiary and the release of the
Company or such Restricted Subsidiary from all liability on such Indebtedness in
connection with such Asset Disposition and (y) securities received by the

          (b)  In the event of an Asset Disposition that requires the purchase
of Securities pursuant to clause (iii)(D) of Section 3.10(a), the Company will
be required to purchase Securities tendered pursuant to an offer by the Company
for the Securities at a purchase price of 100% of their principal amount plus
accrued interest to the purchase date in accordance with the procedures
(including prorating in the event of oversubscription) set forth in Section
3.10(c).

          (c)  (i)  Promptly, and in any event within 10 days after the Company
     is required to make an Offer, the Company shall deliver to the Trustee and
     send, by first class mail to each Holder, a written notice stating that the
     Holder may elect to have his or her Securities purchased by the Company
     either in whole or in part (subject to prorating as hereinafter described
     in the event the Offer is oversubscribed) in integral multiples of $1,000
     of principal amount, at the applicable purchase price. Such notice
     delivered to each Holder shall identify the Security, including CUSIP
     numbers, and shall specify the purchase date, which date shall not be less
     than 30 days nor more than 60 days after the date of such notice (the
     "Purchase Date"), the place or places of payment and that the payment will
     be made upon presentation and surrender of the Security.

                                                                              34

               (ii) Not later than the date upon which such written notice of an
     Offer is delivered to the Trustee and the Holders, the Company shall
     deliver to the Trustee an Officers' Certificate setting forth (A) the
     amount of the Offer (the "Offer Amount"), (B) the allocation of the Net
     Available Cash from the Asset Dispositions as a result of which such Offer
     is being made and (C) the compliance of such allocation with the provisions
     of Section 3.10(a).  Upon the expiration of the period (the "Offer Period")
     for which the Offer remains open, the Company shall deliver to the Trustee
     for cancellation the Securities or portions thereof which have been
     properly tendered to and are to be accepted by the Company.  The Trustee
     shall, on the Purchase Date, mail or deliver payment to each tendering
     Holder in the amount of the purchase price of the Securities tendered by
     such Holder to the extent such funds are available to the Trustee.

               (iii)               Holders electing to have a Security purchased
     will be required to surrender the Security, together with the form entitled
     "Option of Holder to Elect Purchase" on the reverse of the Security duly
     executed, to the Company at the address specified in the notice prior to
     the expiration of the Offer Period.  Each Holder will be entitled to
     withdraw its election if the Trustee or the Company receives, not later
     than one Business Day prior to the expiration of the Offer Period, a
     facsimile transmission or letter from such Holder setting forth the name of
     such Holder, the principal amount of the Security or Securities which were
     delivered for purchase by such Holder and a statement that such Holder is
     withdrawing its election to have such Security or Securities purchased.  If
     at the expiration of the Offer Period the aggregate principal amount of
     Securities surrendered by Holders exceeds the Offer Amount, the Company
     shall select the Securities to be purchased on a pro rata basis (with such
     adjustments as may be deemed appropriate by the Company so that only
     Securities in denominations of $1,000, or integral multiples thereof, shall
     be purchased).  Holders whose Securities are purchased only in part will be

Section 4.1(e) will not constitute an Event of Default until the Trustee or the
Holders of at least 25% in principal amount of the outstanding Securities notify
the Company in writing of the Default and the Company does not cure such Default
within the time specified in said Section 4.1(d) or (e) after receipt of such
notice.  Such notice must specify the Default, demand that it be remedied, and
state that such notice is a "Notice of Default."

          The Company shall deliver to the Trustee:  (i) within 5 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any Event of Default under clause (f) and any event which with the giving of
notice or the lapse of time would become an Event of Default under clause (d),
(e) or (i), its status and what action the Company is taking or proposes to take
with respect thereto and (ii) within 120 days after the end of each fiscal year,
written notice in the form of an Officers' Certificate indicating whether the
Officers signing such Officers' Certificate had actual knowledge of any Default
that occurred during such previous fiscal year.

          SECTION 4.2  Acceleration.  If an Event of Default (other than an
                       ------------                                        
Event of Default specified in Section 4.1(g) or (h) with respect to the Company)
occurs and is continuing, the Trustee, by written notice to the Company, or the
Holders of at least 25% in outstanding principal amount of the Securities, by
written notice to the Company and the Trustee, may declare the principal of, and
accrued and unpaid interest on, all the Securities to be due and payable. Upon
such a declaration, such principal and interest shall be due and payable (i) if
no Indebtedness is outstanding under the Senior Credit Agreement, immediately,
and (ii) if any Indebtedness is outstanding under the Senior Credit Agreement,
upon the first to occur of (x) the acceleration of any such Indebtedness or (y)
the fifth Business Day after receipt by the Company and the Credit Agent of such
written notice of acceleration. If an Event of Default specified in Section
4.1(g) or (h) with respect to the Company occurs and is continuing, the
principal of, and accrued and unpaid interest on, all the Securities shall ipso
                                                                           ----

                                                                              43

facto become and be immediately due and payable without any declaration or other
- -----
act on the part of the Trustee or any Holders. The Holders of a majority in
principal amount of the Securities, by notice to the Trustee, may rescind an
acceleration and its consequences if the rescission would not conflict with any
judgment or decree and if all existing Events of Default have been cured or
waived except nonpayment of principal or interest that has become due solely
because of acceleration. No such rescission shall affect any subsequent Default
or Event of Default or impair any right consequent thereto.

          SECTION 4.3  Other Remedies.  If an Event of Default occurs and is
                       --------------                                       
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the Securities or to enforce the performance of
any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default.  No remedy shall be deemed
exclusive of any other remedy and all available remedies shall be cumulative.

          SECTION 4.4  Waiver of Past Defaults.  The Holders of a majority in
                       -----------------------                               
outstanding principal amount of the Securities, by notice to the Trustee, may
waive an existing Default or Event of Default and its consequences except (i) a
Default or Event of Default in the payment of the principal of or interest on a
Security or (ii) a Default or Event of Default in respect of a provision that
under Section 7.2 cannot be amended without the consent of each Holder affected.
When a Default or Event of Default is waived, it is deemed cured, but no such
waiver shall extend to any subsequent or other Default or Event of Default or
impair any consequent right.

          SECTION 4.5  Control by Majority.  The Holders of a majority in
                       -------------------                               
outstanding principal amount of the Securities may direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee.  However, the Trustee
may refuse to follow any direction that conflicts with law or this Indenture or,
subject to Section 5.1, that the Trustee determines is unduly prejudicial to the
rights of other Holders (it being understood that, subject to Section 5.1, the
Trustee shall have no duty to ascertain whether or not such actions or
forbearances are unduly prejudicial to such Holders) or would subject the
Trustee to personal liability; provided, however, that the Trustee may take any
                               --------  -------                               
other action deemed proper by the Trustee that is not inconsistent with such
direction. Prior to taking or refraining from taking any such action hereunder,
the Trustee shall be entitled to indemnification satisfactory to it in its sole
discretion against all losses and expenses caused by its taking or refraining
from taking such action.

          SECTION 4.6  Limitation on Suits.  Except to enforce the right of any
                       -------------------                                     
Holder to receive payment of the principal of and interest on the Securities
held by such Holder on or

after the respective due dates expressed in the Securities, no Holder may pursue
any remedy with respect to this Indenture or the Securities unless:

          (a)  the Holder gives to the Trustee written notice stating that an
Event of Default is continuing;

          (b)  the Holders of at least 25% in outstanding principal amount of
the Securities make a written request to the Trustee to pursue the remedy;

          (c)  such Holder or Holders offer to the Trustee reasonable security
or indemnity against any loss, liability or expense;

          (d)  the Trustee does not comply with the request within 60 days after
receipt of the request and the offer of security or indemnity; and

          (e)  the Holders of a majority in principal amount of the Securities
do not give the Trustee a direction inconsistent with the request during such
60-day period.

          A Holder may not use this Indenture to prejudice the rights of another
Holder or to obtain a preference or priority over another Holder.

          SECTION 4.7  Rights of Holders to Receive Payment.  Notwithstanding
                       ------------------------------------                  
any other provision of this Indenture, the right of any Holder to receive
payment of the principal of and interest on the Securities held by such Holder
on or after the respective due dates expressed in the Securities, or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of such Holder.

          SECTION 4.8  Collection Suit by Trustee.  If an Event of Default
                       --------------------------                         
specified in Section 4.1(a) or (b) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount then due and owing (together with interest on any
unpaid interest to the extent lawful) and the amounts provided for in Section
5.6.

          SECTION 4.9  Trustee May File Proofs of Claim.  The Trustee may file
                       --------------------------------                       
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Holders allowed in
any judicial proceedings relative to the Company, its Subsidiaries or their
respective creditors or properties and, unless prohibited by law or applicable
regulations, may vote on behalf of the Holders in any election of a trustee in
bankruptcy or other Person performing similar functions, and any Custodian in
any such judicial proceeding is hereby authorized by each Holder to make
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compen sation, expenses, disbursements and
advances of the Trustee, its agents and its counsel, and any other amounts due
the Trustee under Section 5.6.

          SECTION 4.10  Priorities.  If the Trustee collects any money or
                        ----------                                       
property pursuant to this Article IV, it shall pay out the money or property in
the following order:

          FIRST:  Costs and expenses of collection, including all sums paid or
     advanced by the Trustee hereunder and the reasonable compensation, expenses
     and disbursements of the Trustee, its agents, and counsel and all other
     amounts due to the Trustee under Section 5.6;

          SECOND:  To Holders for amounts due and unpaid on the Securities for
     principal and interest, without preference or priority of any kind,
     according to the amounts due and payable on the Securities for principal
     and interest, respectively; and

          THIRD:  To the Company.

          The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 4.10.  At least 15 days before such record
date, the Company shall mail to each Holder and the Trustee a notice that states
the record date, the payment date and the amount to be paid.

          SECTION 4.11  Undertaking for Costs.  In any suit for the enforcement
                        ---------------------                                  
of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or defenses
made by the party litigant.  This Section 4.11 does not apply to a suit by the
Trustee, a suit by a Holder pursuant to Section 4.7 or a suit by Holders of more
than 10% in outstanding principal amount of the Securities.

                                   ARTICLE V

                             CONCERNING THE TRUSTEE
                             ----------------------

          SECTION 5.1  Duties and Responsibilities of the Trustee; During
                       --------------------------------------------------
Default; Prior to Default.  The Trustee, prior to the occurrence of an Event of
- -------------------------                                                      
Default and after the curing or waiving of all Events of Default that may have
occurred, undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture.  In case an Event of Default has
occurred that has not been cured or waived, the Trustee shall exercise such of
the rights and powers vested in it by this Indenture, and use the same degree of
care and skill in their exercise, as a prudent man would exercise or use under
the circumstances in the conduct of his own affairs. The Trustee shall not be
charged with knowledge of the existence of an Event of Default, other than with
respect to a payment default, unless and until the Trustee has actual knowledge
of such Event of Default or the Trustee shall have received notice thereof in
writing from the Company or from the holders of a majority in principal amount
of the Securities.

                                                                              46

          No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own wilful misconduct, except that

          (a)  prior to the occurrence of an Event of Default and after the
curing or waiving of all such Events of Default that may have occurred:

               (i) the duties and obligations of the Trustee shall be determined
     solely by the express provisions of this Indenture, and the Trustee shall
     not be liable except for the performance of such duties and obligations as
     are specifically set forth in this Indenture, and no implied covenants or
     obligations shall be read into this Indenture against the Trustee; and

               (ii) in the absence of bad faith on the part of the Trustee, the
     Trustee may conclusively rely, as to the truth of the statements and the
     correctness of the opinions expressed therein, upon any statements,
     certificates or opinions furnished to the Trustee and conforming to the
     requirements of this Indenture; but in the case of any such statements,
     certificates or opinions that are specifically required by any provision
     hereof to be furnished to the Trustee, the Trustee shall be under a duty to
     examine the same to determine whether or not they conform to the
     requirements of this Indenture;

          (b)  the Trustee shall not be liable for any error of judgment made in
good faith by a responsible officer or responsible officers of the Trustee,
unless it shall be proved that the Trustee was negligent in ascertaining the
pertinent facts; and

          (c)  the Trustee shall not be liable with respect to any action taken
or omitted to be taken by it in good faith in accordance with the direction of
the holders of not less than a majority in principal amount of the Securities at
the time outstanding relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred upon the Trustee, under this Indenture.

          None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there shall be reasonable ground for believing that the
repayment of such funds or adequate indemnity against such liability is not
reasonably assured to it.

          This Section 5.1 is in furtherance of and subject to Sections 315 and
316 of the Trust Indenture Act.

          SECTION 5.2  Certain Rights of the Trustee.  In furtherance of and

subject to the Trust Indenture Act, and subject to Section 5.1:

          (a)  the Trustee may conclusively rely and shall be protected in

resolution of the Board of Directors may be evidenced to the Trustee by a copy
thereof certified by the secretary or an assistant secretary of the Company;

          (c)  the Trustee may consult with counsel of its selection and any
advice or Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted to be taken by it
hereunder in good faith and in reliance on such advice or Opinion of Counsel;

          (d)  the Trustee shall be under no obligation to exercise any of the
trusts or powers under this Indenture at the request, order or direction of any
of the Securityholders pursuant to the provisions of this Indenture, unless such
Securityholders shall have offered to the Trustee indemnification satisfactory
to it in its sole discretion against all losses and expenses;

          (e)  the Trustee shall not be liable for any action taken or omitted
by it in good faith and believed by it to be authorized or within the
discretion, rights or powers conferred upon it by this Indenture;

          (f)  prior to the occurrence of an Event of Default hereunder and
after the curing or waiving of all Events of Default, the Trustee shall not be
bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, appraisal, bond, debenture, note, coupon,
security, or other paper or document unless requested in writing to do so by the
holders of not less than a majority in aggregate principal amount of the
Securities then outstanding; provided that, if the payment within a reasonable
                             --------                                         
time to the Trustee of the costs, expenses or liabilities likely to be incurred
by it in the making of such investigation is, in the opinion of the Trustee, not
reasonably assured to the Trustee by the security afforded to it by the terms of
this Indenture, the Trustee may require reasonable indemnity against such costs,
expenses or liabilities as a condition to proceeding; the reasonable expenses of
every such examination shall be paid by the Company or, if paid by the Trustee
or any predecessor trustee, shall be repaid by the Company upon demand; and

          (g)  the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys not regularly in its employ and the Trustee shall not be responsible
for any misconduct or negligence on the part of any such agent or attorney
appointed with due care by it hereunder.

          SECTION 5.3  Trustee Not Responsible for Recitals, Disposition of
                       ----------------------------------------------------
Securities or Application of Proceeds Thereof.  The recitals contained herein
- ---------------------------------------------                                
and in the Securities, except the Trustee's certificates of authentication,
shall be taken as the statements of the 
<PAGE>
 
                                                                              48

Company, and the Trustee assumes no responsibility for the correctness of the
same. The Trustee makes no representation as to the validity or sufficiency of
this Indenture or of the Securities. The Trustee shall not be accountable for
the use or application by the Company of any of the Securities or of the
proceeds thereof.

          SECTION 5.4  Trustee and Agents May Hold Securities; Collections, etc.
                       --------------------------------------------------------
The Trustee or any agent of the Company or the Trustee, in its individual or any
other capacity, may become the owner or pledgee of Securities with the same
rights it would have if it were not the Trustee or such agent and may otherwise
deal with the Company and receive, collect, hold and retain collections from the
Company with the same rights it would have if it were not the Trustee or such
agent.

          SECTION 5.5  Moneys Held by Trustee.  Subject to the provisions of
                       ----------------------                               
Section 9.6, all moneys received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were received,
but need not be segregated from other funds except to the extent required by
mandatory provisions of law.  Neither the Trustee nor any agent of the Company
or the Trustee shall be under any liability for interest on any moneys received
by it hereunder.

          SECTION 5.6  Compensation and Indemnification of Trustee and Its Prior
                       ---------------------------------------------------------
Claim.  The Company covenants and agrees to pay to the Trustee from time to
- -----                                                                      
time, and the Trustee shall be entitled to, such compensation as agreed to by
the Company and the Trustee (which shall not be limited by any provision of law
in regard to the compensation of a trustee of an express trust), and the Company
covenants and agrees to pay or reimburse the Trustee and each predecessor
trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by or on behalf of it in accordance with any of the provisions
of this Indenture (including the reasonable compensation and the expenses and
disbursements of its counsel and of all agents and other persons not regularly
in its employ) except any such expense, disbursement or advance as may arise
from its negligence or bad faith.  The Company also covenants to indemnify the
Trustee and each predecessor trustee for, and to hold it harmless against, any
loss, liability or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of this
Indenture or the trusts hereunder and its duties hereunder, including the costs
and expenses of enforcing this Indenture against the Company (including this
Section 5.6) and of defending itself against or investigating any claim (whether
asserted by a Holder or the Company) of liability in the premises.  The
obligations of the Company under this Section to compensate and indemnify the
Trustee and each predecessor trustee and to pay or reimburse the Trustee and
each predecessor trustee for expenses, disbursements and advances shall
constitute additional indebtedness hereunder and shall survive the satisfaction
and discharge of this Indenture. Such additional indebtedness shall be a lien
prior to that of the Securities upon all property and funds held or collected by
the Trustee as such, except funds held in trust for the benefit of the holders
of particular Securities, and the Securities are hereby subordinated to such
senior claim.

          SECTION 5.7  Right of Trustee to Rely on Officer's Certificate, Etc.
                       ------------------------------------------------------  
Subject to Sections 5.1 and 5.2, whenever in the administration of the trusts of
this Indenture the

                                                                              49

Trustee shall deem it necessary or desirable that a matter be proved or
established prior to taking or suffering or omitting any action hereunder, such
matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of negligence or bad faith on the part of the
Trustee, be deemed to be conclusively proved and established by an Officers'
Certificate delivered to the Trustee, and such certificate, in the absence of
negligence or bad faith on the part of the Trustee, shall be full warrant to the
Trustee for any action taken, suffered or omitted by it under the provisions of
this Indenture upon the faith thereof.

          SECTION 5.8  Persons Eligible for Appointment as Trustee.  The Trustee
                       -------------------------------------------              
hereunder shall at all times be a corporation having a combined capital and
surplus of at least $50,000,000, and which is eligible in accordance with the
provisions of Section 310(a) of the Trust Indenture Act.  If such corporation
publishes reports of condition at least annually, pursuant to law or to the
requirements of a Federal, State or District of Columbia supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.

          SECTION 5.9  Resignation and Removal; Appointment of Successor
                       -------------------------------------------------
Trustee.  (a)  The Trustee may at any time resign by giving written notice of
resignation to the Company and by mailing notice thereof by first-class mail to
holders of Securities at their last addresses as they shall appear on the
Security register.  Upon receiving such notice of resignation, the Company shall
promptly appoint a successor trustee by written instrument in duplicate,
executed by authority of the Board of Directors, one copy of which instrument
shall be delivered to the resigning Trustee and one copy to the successor
trustee.  If no successor trustee shall have been so appointed and have accepted
appointment within 30 days after the mailing of such notice of resignation, the
resigning trustee may petition any court of competent jurisdiction for the
appointment of a successor trustee, or any Securityholder who has been a bona
fide holder of a Security or Securities for at least six months may, on behalf
of himself and all others similarly situated, petition any such court for the
appointment of a successor trustee.  Such court may thereupon, after such
notice, if any, as it may deem proper, prescribe and appoint a successor
trustee.

          (b)  In case at any time any of the following shall occur:

               (i)   the Trustee shall fail to comply with the provisions of
     Section 310(b) of the Trust Indenture Act, after written request therefor
     by the Company or by any Securityholder who has been a bona fide holder of
     a Security or Securities for at least six months; or

               (ii)  the Trustee shall cease to be eligible in accordance with
     the provisions of Section 5.8 and shall fail to resign after written
     request therefor by the Company or by any such Securityholder; or

               (iii) the Trustee shall become incapable of acting, or shall
     be adjudged a bankrupt or insolvent, or a receiver or liquidator of the
     Trustee or of its property shall

     be appointed, or any public officer shall take charge or control of the
     Trustee or of its property or affairs for the purpose of rehabilitation,
     conservation or liquidation;

then, in any such case, the Company may remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed by order of the
Board of Directors of the Company, one copy of which instrument shall be
delivered to the Trustee so removed and one copy to the successor trustee, or,
subject to Section 315(e) of the Trust Indenture Act, the Trustee or any
Securityholder who has been a bona fide holder of a Security or Securities for
at least six months may on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor trustee.  Such court may thereupon, after such
notice, if any, as it may deem proper and prescribe, remove the Trustee and
appoint a successor trustee.

          (c)  The holders of a majority in aggregate principal amount of the
Securities at the time outstanding may at any time remove the Trustee and
appoint a successor trustee by delivering to the Trustee so removed, to the
successor trustee so appointed and to the Company the evidence provided for in
Section 6.1 of the action in that regard taken by the Securityholders.

          (d)  Any resignation or removal of the Trustee and any appointment of
a successor trustee pursuant to any of the provisions of this Section 5.9 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 5.10.

          SECTION 5.10  Acceptance of Appointment by Successor Trustee.  Any
                        ----------------------------------------------      
successor trustee appointed as provided in Section 5.9 shall execute and deliver
to the Company and to its predecessor trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all rights,
powers, duties and obligations of its predecessor hereunder, with like effect as
if originally named as trustee herein; but, nevertheless, on the written request
of the Company or of the successor trustee, upon payment of its charges then
unpaid, the trustee ceasing to act shall, subject to Section 9.6, pay over to
the successor trustee all moneys at the time held by it hereunder and shall
execute and deliver an instrument transferring to such successor trustee all
such rights, powers, duties and obligations.  Upon request of any such successor
trustee, the Company shall execute any and all instruments in writing for more
fully and certainly vesting in and confirming to such successor trustee all such
rights and powers. Any trustee ceasing to act shall, nevertheless, retain a
prior claim upon all property or funds held or collected by such trustee to
secure any amounts then due it pursuant to the provisions of Section 5.6.

          Upon acceptance of appointment by a successor trustee as provided in
this Section 5.10, the Company shall mail notice thereof by first-class mail to
the holders of Securities at their last addresses as they shall appear in the
Security register.  If the acceptance of appointment is substantially
contemporaneous with the resignation, then the notice called for by the
preceding sentence may be combined with the notice called for by Section 5.9.
If the Company fails to mail such notice within 10 days after acceptance of
appointment by the

                                                                              51

successor trustee, the successor trustee shall cause such notice to be mailed at
the expense of the Company.

          SECTION 5.11  Merger, Conversion, Consolidation or Succession to
                        --------------------------------------------------
Business of Trustee.  Any corporation into which the Trustee may be merged or
- -------------------                                                          
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided that such
                                                          --------          
corporation shall be eligible under the provisions of Section 5.8, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, anything herein to the contrary notwithstanding.

          In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture any of the Securities shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the
certificate of authentication of any predecessor trustee and deliver such
Securities so authenticated; and, in case at that time any of the Securities
shall not have been authenticated, any successor to the Trustee may authenticate
such Securities either in the name of any predecessor hereunder or in the name
of the successor trustee; and in all such cases such certificate shall have the
full force which it is anywhere in the Securities or in this Indenture; provided
                                                                        --------
that the certificate of the Trustee shall have provided that the right to adopt
the certificate of authentication of any predecessor trustee or to authenticate
Securities in the name of any predecessor trustee shall apply only to its
successor or successors by merger, conversion or consolidation.

          SECTION 5.12  Notice of Defaults.  If a Default or Event of Default
                        ------------------                                   
occurs and is continuing and if a Trust Officer has actual knowledge thereof,
the Trustee shall mail to each Holder notice of the Default or Event of Default
within 90 days after it occurs.  Except in the case of a Default or Event of
Default in payment of principal of, or interest on, any Security (including
payments pursuant to the optional redemption or required repurchase provisions
of such Security, if any), the Trustee may withhold the notice if and so long as
its board of directors, the Executive Committee of its board of directors or a
committee of its Trust Officers in good faith determines that withholding the
notice is in the interests of Securityholders.

          SECTION 5.13  Reports by the Trustee.  The Trustee shall by October 1
                        ----------------------                                 
of each year transmit to the Holders all reports required under Section 313(a)
of the Trust Indenture Act.

                                   ARTICLE VI

                         CONCERNING THE SECURITYHOLDERS
                         ------------------------------

          SECTION 6.1  Evidence of Action Taken by Securityholders.  Any
                       -------------------------------------------      
request, demand, authorization, direction, notice, consent, waiver or other
action provided by this Indenture to be given or taken by Securityholders may be
embodied in and evidenced by one 
<PAGE>
 
                                                                              52

or more instruments of substantially similar tenor signed by such
Securityholders in person or by agent duly appointed in writing; and, except as
herein otherwise expressly provided, such action shall become effective when
such instrument or instruments are delivered to the Trustee. Proof of execution
of any instrument or of a writing appointing any such agent shall be sufficient
for any purpose of this Indenture and (subject to Sections 5.1 and 5.2)
conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Article.

          SECTION 6.2  Proof of Execution of Instruments and of Holding of
                       ---------------------------------------------------
Securities; Record Date.  Subject to Sections 5.1 and 5.2, the execution of any
- -----------------------                                                        
instrument by a Securityholder or his agent or proxy may be proved in accordance
with such reasonable rules and regulations as may be prescribed by the Trustee
or in such manner as shall be satisfactory to the Trustee.  The holding of
Securities shall be proved by the Security register or by a certificate of the
registrar thereof.  The Company may set a record date for purposes of
determining the identity of holders of Securities entitled to vote or consent to
any action referred to in Section 6.1, which record date may be set at any time
or from time to time by notice to the Trustee, for any date or dates (in the
case of any adjournment or resolicitation) not more than 60 days nor less than
five days prior to the proposed date of such vote or consent, and thereafter,
notwithstanding any other provisions hereof, only holders of Securities of
record on such record date shall be entitled to so vote or give such consent or
to withdraw such vote or consent.

          SECTION 6.3  Holders to be Treated as Owners.  The Company, the
                       -------------------------------                   
Trustee and any agents of the Company or the Trustee may deem and treat the
person in whose name any Security shall be registered upon the Security register
as the absolute owner of such Security (whether or not such Security shall be
overdue and notwithstanding any notation of ownership or other writing thereon)
for the purpose of receiving payment of or on account of the principal of and,
subject to the provisions of this Indenture, interest on such Security and for
all other purposes; and neither the Company nor the Trustee nor any agent of the
Company or the Trustee shall be affected by any notice to the contrary;
                                                                       
provided, however, that the Depository, or its nominee, shall be deemed the
- --------  -------                                                          
owner of the Restricted Global Security, and owners of beneficial interests in
the Restricted Global Security will not be considered the owners of any
Securities.  All such payments so made to any such person, or upon his order,
shall be valid, and, to the extent of the sum or sums so paid, effectual to
satisfy and discharge the liability for moneys payable upon any such Security.

          SECTION 6.4  Securities Owned by Company Deemed Not Outstanding.  In
                       --------------------------------------------------     
determining whether the holders of the requisite aggregate principal amount of
Securities have concurred in any direction, consent or waiver under this
Indenture, Securities which are owned by the Company or any other obligor on the
Securities or by any person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Company or any other obligor
on the Securities shall be disregarded and deemed not to be outstanding for the
purpose of any such determination, except that for the purpose of determining
whether the Trustee shall be protected in relying on any such direction, consent
or waiver only Securities which the Trustee knows are so owned shall be so
disregarded.  Securities so owned which have been pledged in good faith may be
regarded as outstanding if the pledgee establishes to the satisfaction of the
Trustee the pledgee's right so to act with 
<PAGE>
 
                                                                              53

respect to such Securities and that the pledgee is not the Company or any other
obligor upon the Securities or any person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company or any
other obligor on the Securities. In case of a dispute as to such right, the
advice of counsel shall be full protection in respect of any decision made by
the Trustee in accordance with such advice. Upon request of the Trustee, the
Company shall furnish to the Trustee promptly an Officers' Certificate listing
and identifying all Securities, if any, known by the Company to be owned or held
by or for the account of any of the above-described persons; and, subject to
Sections 5.1 and 5.2, the Trustee shall be entitled to accept such Officers'
Certificate as conclusive evidence of the facts therein set forth and of the
fact that all Securities not listed therein are outstanding for the purpose of
any such determination.

          SECTION 6.5  Right of Revocation of Action Taken.  At any time prior
                       -----------------------------------                    
to (but not after) the evidencing to the Trustee, as provided in Section 6.1, of
the taking of any action by the holders of the percentage in aggregate principal
amount of the Securities specified in this Indenture in connection with such
action, any holder of a Security the serial number of which is shown by the
evidence to be included among the serial numbers of the Securities the holders
of which have consented to such action may, by filing written notice at the
Corporate Trust Office and upon proof of holding as provided in this Article,
revoke such action so far as concerns such Security.  Except as aforesaid, any
such action taken by the holder of any Security shall be conclusive and binding
upon such holder and upon all future holders and owners of such Security and of
any Securities issued in exchange or substitution therefor, irrespective of
whether or not any notation in regard thereto is made upon any such Security.
Any action taken by the holders of the percentage in aggregate principal amount
of the Securities specified in this Indenture in connection with such action
shall be conclusively binding upon the Company, the Trustee and the holders of
all the Securities.


                                  ARTICLE VII

                                   AMENDMENTS
                                   ----------

          SECTION 7.1  Without Consent of Holders.  The Company and the Trustee
                       --------------------------                              
may amend this Indenture or the Securities without notice to or consent of any
Holder:

          (a)  to cure any ambiguity, omission, defect or inconsistency;

          (b)  to comply with Article VIII;

          (c)  to provide for uncertificated Securities in addition to or in
place of certificated Securities; provided, however, that the uncertificated
                                  --------  -------                         
Securities are issued in registered form for purposes of Section 163(f) of the
Code or in a manner such that the uncertificated Securities are described in
Section 163(f)(2)(B) of the Code;

          (d)  to add Guarantees with respect to the Securities or to secure the
Securities;
<PAGE>
 
                                                                              54

          (e)  to add to the covenants of the Company for the benefit of the
Holders of the Securities or to surrender any right or power herein conferred
upon the Company;

          (f)  to comply with any requirements of the Commission in connection
with qualifying this Indenture under the Trust Indenture Act;

          (g)  to make any change that does not adversely affect the rights of
any Holder; or

          (h)  to provide for the issuance of the Exchange Notes, which will
have terms substantially identical in all material respects to the Initial Notes
(except that the transfer restrictions contained in the Initial Notes will be
modified or eliminated, as appropriate), and which will be treated, together
with any outstanding Initial Notes, as a single issue of securities.

          After an amendment under this Section 7.1 becomes effective, the
Company shall mail to each Holder a notice briefly describing such amendment.
The failure to give such notice to all Holders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section 7.1.

          SECTION 7.2  With Consent of Holders.  The Company and the Trustee may
                       -----------------------                                  
amend this Indenture or the Securities without notice to any Holder but with the
written consent of the Holders of at least a majority in principal amount of the
Securities.  However, without the consent of each Holder of an outstanding
Security affected, no amendment may:

          (a)  reduce the amount of Securities whose Holders must consent to an
amendment;

          (b)  reduce the rate of or extend the time for payment of interest on
any Security;

          (c)  reduce the principal of or extend the Stated Maturity of any
Security;

          (d)  reduce the premium payable upon the redemption or repurchase of
any Security or change the time at which any Security may or shall be redeemed
or repurchased in accordance with this Indenture;

          (e)  make any Security payable in money other than that stated in the
Security;

          (f)  modify or affect in any manner adverse to the Holders, the terms
and conditions of the obligation of the Company for the due and punctual payment
of the principal of or interest on Securities; or

          (g)  make any change in Section 4.4 or 4.7 or the second sentence of
this Section 7.2.
<PAGE>
 
                                                                              55

          It shall not be necessary for the consent of the Holders under this
Section to approve the particular form of any proposed amendment, but it shall
be sufficient if such consent approves the substance thereof.

          After an amendment under this Section 7.2 becomes effective, the
Company shall mail to Holders a notice briefly describing such amendment.  The
failure to give such notice to all Holders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section 7.2.

          SECTION 7.3  Compliance with Trust Indenture Act.  Every amendment to
                       -----------------------------------                     
this Indenture or the Securities shall comply with the Trust Indenture Act as
then in effect.

          SECTION 7.4  Revocation and Effect of Consents and Waivers.  A consent
                       ---------------------------------------------            
to an amendment or a waiver by a Holder of a Security shall bind the Holder and
every subsequent Holder of that Security or portion of the Security that
evidences the same debt as the consenting Holder's Security, even if notation of
the consent or waiver is not made on the Security.  However, any such Holder or
subsequent Holder may revoke the consent or waiver as to such Holder's Security
or portion of Security if the Trustee receives the notice of revocation before
the date the amendment or waiver becomes effective.  After an amendment or
waiver becomes effective, it shall bind every Holder.

          The Company may, but shall not be obligated to, fix a record date for
the  purpose of determining the Holders entitled to give their consent or take
any other action described above or required or permitted to be taken pursuant
to this Indenture.  If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Holders at such record
date (or their duly designated proxies), and only those Persons, shall be
entitled to give such consent or to revoke any consent previously given or to
take any such action, whether or not such Persons continue to be Holders after
such record date.  No such consent shall become valid or effective more than 120
days after such record date.

          SECTION 7.5  Notation on or Exchange of Securities.  If an amendment
                       -------------------------------------                  
changes the terms of a Security, the Trustee may require the Holder of the
Security to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the
Holder. Alternatively, if the Company or the Trustee so determines, the Company
in exchange for the Security shall issue and the Trustee shall authenticate a
new Security that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Security shall not affect the validity of such
amendment.

          SECTION 7.6  Trustee to Sign Amendments.  The Trustee shall sign any
                       --------------------------                             
amendment authorized pursuant to this Article VII if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it.  In signing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Section 7.1) shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel stating that such
amendment is authorized or permitted by this Indenture.

          SECTION 8.1  When Company May Merge, Etc.  The Company shall not
                       ----------------------------                       
consolidate with or merge with or into, or convey, transfer or lease all or
substantially all its assets to, any Person, unless: (i) the resulting,
surviving or transferee Person (the "Successor Company") shall be a Person
organized and existing under the laws of the United States of America, any state
thereof or the District of Columbia and the Successor Company (if not the
Company) shall expressly assume, by an indenture supplemental to this Indenture,
executed and delivered to the Trustee, in form reasonably satisfactory to the
Trustee, all the obligations of the Company under the Securities and this
Indenture; (ii) immediately after giving effect to such transaction (and
treating any Indebtedness which becomes an obligation of the Successor Company
or any Restricted Subsidiary as a result of such transaction as having been
incurred by such Successor Company or such Restricted Subsidiary at the time of
such transaction), no Event of Default shall have occurred and be continuing;
(iii) immediately after giving pro forma effect to such transaction, as if such
transaction had occurred at the beginning of the applicable four-quarter period,
the Successor Company would be permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Consolidated Coverage Ratio test set forth in
Section 3.8(a); and (iv) the Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that such
consolidation, merger or transfer and such supplemental indenture (if any)
comply with this Indenture.

          SECTION 8.2  Successor Corporation Substituted.  The Successor Company
                       ---------------------------------                        
shall be the successor of the Company and shall succeed to, and be substituted
for, and may exercise every right and power of, the Company under this
Indenture, but the predecessor Company in the case of a conveyance, transfer or
lease shall not be released from the obligation to pay the principal of and
interest on the Securities.

          Such Successor Company may cause to be signed, and may issue either in
its own name or in the name of the Company prior to such succession any or all
of the Securities issuable hereunder which theretofore shall not have been
signed by the Company
and delivered to the Trustee; and, upon the order of such successor corporation,
instead of the Company, and subject to all the terms, conditions and limitations
in this Indenture prescribed, the Trustee shall authenticate and shall deliver
any Securities which previously shall have been signed and delivered by the
officers of the Company to the Trustee for authentication, and any Securities
which such successor corporation thereafter shall cause to be signed and
delivered to the Trustee for that purpose.  All of the Securities so issued
shall in all respects have the same legal rank and benefit under this Indenture
as the Securities theretofore or thereafter issued in accordance with the terms
of this Indenture as though all of such Securities had been issued at the date
of the execution hereof.

          In case of any such consolidation, merger, sale, lease or conveyance
such changes in phraseology and form (but not in substance) may be made in the
Securities thereafter to be issued as may be appropriate.

          In the event of any such sale or conveyance (other than a conveyance
by way of lease) the Company or any Successor Company which shall theretofore
have become such in the manner described in this Article shall be discharged
from all obligations and covenants under this Indenture and the Securities and
may be liquidated and dissolved.

                       ----------------------------------

          SECTION 9.1  Discharge of Liability on Securities: Defeasance.  (a)
                       ------------------------------------------------       
When (i) the Company delivers to the Trustee all outstanding Securities (other
than Securities replaced pursuant to Section 2.6) for cancellation or (ii) all
outstanding Securities have become due and payable, whether at maturity or as a
result of the mailing of a notice of redemption pursuant to Article XII and the
Company irrevocably deposits with the Trustee funds sufficient to pay at
maturity or upon redemption all outstanding Securities (other than Securities
replaced pursuant to Section 2.6), including interest thereon to maturity or
such redemption date, and if in either case the Company pays all other sums
payable hereunder by the Company, then this Indenture shall, subject to Section
9.1(c), cease to be of further effect.  The Trustee shall acknowledge
satisfaction and discharge of this Indenture on demand of the Company
(accompanied by an Officers' Certificate and an Opinion of Counsel stating that
all conditions precedent specified herein relating to the satisfaction and
discharge of this Indenture have been complied with) and at the cost and expense
of the Company.

          (b)  Subject to Sections 9.1(c) and 9.2, the Company at any time may
terminate (i) all its obligations under the Securities and this Indenture and
all obligations of the Subsidiary Guarantors under the Subsidiary Guarantee and
this Indenture ("legal defeasance option") or (ii) its obligations under
Sections 3.5, 3.7 through 3.19, 8.1(iii) and 8.1(iv) and the operation of
Sections 4.1(d), 4.1(e), 4.1(f) and 4.1(i) ("covenant defeasance option");
provided, however, no deposit under this Article IX shall be effective to
- --------  -------                                                        
terminate the obligations of the Company under the Securities or this Indenture
prior to 123 days following any such deposit. The Company may exercise its legal
defeasance option notwithstanding its prior exercise of its covenant defeasance
option.

          If the Company exercises its legal defeasance option, payment of the
Securities may not be accelerated because of an Event of Default.  If the
Company exercises its covenant defeasance option, payment of the Securities may
not be accelerated because of an Event of Default specified in Sections 4.1(d),
(e), (f), (i) or (j) or because of the failure of the Company to comply with
Section 8.1(iii) and Section 8.1(iv).

          Upon satisfaction of the conditions set forth herein and upon request
of the Company, the Trustee shall acknowledge in writing the discharge of those
obligations that the Company terminates.

          (c)  Notwithstanding the provisions of Sections 9.1(a) and (b), the
Company's obligations in Article II, Sections 5.6, 5.9, 9.4, 9.5 and 9.6 shall
survive until the Securities

have been paid in full. Thereafter, the Company's obligations in Sections 5.6,
9.4 and 9.5 shall survive.

          SECTION 9.2  Conditions to Defeasance.  The Company may exercise its
                       ------------------------                               
legal defeasance option or its covenant defeasance option only if:

          (a)  the Company irrevocably deposits in trust with the Trustee money
or U.S. Government Obligations for the payment of principal of and interest on
the Securities to maturity or redemption, as the case may be;

          (b)  the Company delivers to the Trustee a certificate from a
nationally recognized firm of independent accountants expressing their opinion
that the payments of principal and interest when due and without reinvestment of
the deposited U.S. Government Obligations plus any deposited money without
investment will provide cash at such times and in such amounts as will be
sufficient to pay principal and interest when due on all the Securities to
maturity or redemption, as the case may be;

          (c)  no Event of Default shall have occurred or be continuing on the
date of such deposit and 123 days pass after the deposit is made and during the
123-day period no Default specified in Section 4.1(g) or 4.1(h) with respect to
the Company occurs which is continuing at the end of such period;

          (d)  the deposit does not constitute a default under any other
agreement binding on the Company;

          (e)  the Company delivers to the Trustee an Opinion of Counsel to the
effect that the trust resulting from the deposit does not constitute, or is
qualified as, a regulated investment company under the Investment Company Act of
1940;

          (f)  in the case of the legal defeasance option, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (A) the Company
has received from, or there has been published by, the Internal Revenue Service
a ruling, or (B) since the date hereof there has been a change in the applicable
Federal income tax law, in either case to the effect that, and based thereon
such Opinion of Counsel shall confirm that, the Holders will not recognize
income, gain or loss for Federal income tax purposes as a result of such
defeasance and will be subject to Federal income tax purposes on the same
amounts, in the same manner and at the same times as would have been the case if
such legal defeasance had not occurred;

          (g)  in the case of the covenant defeasance option, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders will not recognize income, gain or loss for Federal income tax purposes
as a result of such covenant defeasance and will be subject to Federal income
tax on the same amounts, in the same manner and at the same times as would have
been the case if such covenant defeasance had not occurred;

                                                                              59

          (h)  The Holders shall have a perfected security interest under
applicable law in the cash or U.S. Government Obligations deposited pursuant to
Section 9.2(a);

          (i)  The Company shall have delivered to the Trustee an Opinion of
Counsel, in form and substance reasonably satisfactory to the Trustee, to the
effect that, after the passage of 123 days following the deposit, the trust
funds will not be subject to any applicable bankruptcy, insolvency,
reorganization or similar law affecting creditors' rights generally;

          (j)  such defeasance shall not cause the Trustee to have a conflicting
interest with respect to any securities of the Company; and

          (k)  the Company delivers to the Trustee an Officers' Certificate and
an Opinion of Counsel, each stating that all conditions precedent to the
defeasance and discharge of the Securities and this Indenture as contemplated by
this Article IX have been complied with.

          Before or after a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date in
accordance with Article III.

          SECTION 9.3  Application of Trust Money.  The Trustee shall hold in
                       --------------------------                            
trust money or U.S. Government Obligations deposited with it pursuant to this
Article IX.  It shall apply the deposited money and the money from U.S.
Government Obligations through the paying agent and in accordance with this
Indenture to the payment of principal of and interest on the Securities.

          SECTION 9.4  Repayment to Company.  The Trustee and the paying agent
                       --------------------                                   
shall promptly turn over to the Company upon request any excess money or
securities held by them upon payment of all the obligations under this
Indenture.

          Subject to any applicable abandoned property law, the Trustee and the
paying agent shall pay to the Company upon request any money held by them for
the payment of principal of or interest on the Securities that remains unclaimed
for two years, and, thereafter, Holders entitled to the money must look to the
Company for payment as general creditors.

          SECTION 9.5  Indemnity for U.S. Government Obligations.  The Company
                       -----------------------------------------              
shall pay and shall indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against deposited U.S. Government Obligations or the
principal and interest received on such U.S. Government Obligations.

          SECTION 9.6  Reinstatement.  If the Trustee or paying agent is unable
                       -------------                                           
to apply any money or U.S. Government Obligations in accordance with this
Article IX by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the obligations of the Company and the
Subsidiary Guarantors under this Indenture and the Securities shall be revived
and reinstated as though no deposit had occurred pursuant to this Article IX
until such time as the Trustee or paying agent is permitted to apply all such
money

                                                                              60

or U.S. Government Obligations in accordance with this Article IX;
provided, however, that, if the Company has made any payment of interest on or
- --------  -------                                                             
principal of any Securities because of the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Securities to
receive such payment from the money or U.S. Government Obligations held by the
Trustee or paying agent.


                                   ARTICLE X

                              SUBSIDIARY GUARANTEE
                              --------------------

          SECTION 10.1  Subsidiary Guarantee.  Each Guarantor hereby
                        --------------------                        
unconditionally guarantees (each a "Subsidiary Guarantee") on a senior unsecured
basis to each Holder and to the Trustee and its successors and assigns the
performance and punctual payment when due, whether at maturity, by acceleration
or otherwise, of all obligations of the Company under this Indenture and the
Securities.  The Guarantor further agrees that the obligations of the Company
may be extended or renewed, in whole or in part, without notice or further
assent from such Guarantor, and that such Guarantor will remain bound under this
Article X notwithstanding any extension or renewal of any such obligation.

          Each Guarantor waives presentation to, demand of, payment from and
protest to the Company of any of the Company's obligations and also waives
notice of protest for nonpayment.  Each Guarantor waives notice of any default
under the Securities or the Company's obligations.  The obligations of any
Guarantor hereunder shall not be affected by (a) the failure of any Holder or
the Trustee to assert any claim or demand or to enforce any right or remedy
against the Company or any other Person under this Indenture, the Securities or
any other agreement or otherwise; (b) any extension or renewal of any thereof;
(c) any rescission, waiver, amendment or modification of any of the terms or
provisions of this Indenture, the Securities or any other agreement; (d) the
release of any security held by any Holder or the Trustee for the obligations of
the Company or any of them; (e) the failure of any Holder or Trustee to exercise
any right or remedy against any other guarantor of the obligations of the
Company; or (f) any change in the ownership of such Guarantor.

          Each Guarantor further agrees that its Subsidiary Guarantee
constitutes a guarantee of payment, performance and compliance when due (and not
a guarantee of collection) and waives any right to require that any resort be
had by any Holder or the Trustee to any security held for payment of the
obligations of the Company.

          The obligations of each Guarantor hereunder shall not be subject to
any reduction, limitation, impairment or termination for any reason, including
any claim of waiver, release, surrender, alteration or compromise, and shall not
be subject to any defense of set-off, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or unenforceability of the
obligations or otherwise.  Without limiting the generality of the foregoing, the
obligations of each Guarantor herein shall not be discharged or impaired or
otherwise affected by the failure of any Holder or the Trustee to assert any
claim or demand or to enforce any remedy under this Indenture, the Securities or
any other agreement, 
<PAGE>
 
                                                                              61

by any waiver or modification of any thereof, by any default, failure or delay,
willful or otherwise, in the performance of the obligations, or by any other act
or thing or omission or delay to do any other act or thing which may or might in
any manner or to any extent vary the risk of such Guarantor or would otherwise
operate as a discharge of such Guarantor as a matter of law or equity.

          Each Guarantor further agrees that its Subsidiary Guarantee shall
continue to be effective or be reinstated, as the case may be, if at any time
payment, or any part thereof, of principal of or interest on any obligation is
rescinded or must otherwise be restored by any Holder or the Trustee upon the
bankruptcy or reorganization of the Company or otherwise.

          In furtherance of the foregoing and not in limitation of any other
right that any Holder or the Trustee has at law or in equity against any
Guarantor by virtue hereof, upon the failure of the Company to pay the principal
of or interest on any of the Securities when and as the same shall become due,
whether at maturity, by acceleration, by redemption or otherwise, or to perform
or comply with any other monetary obligation of the Company under this Indenture
or the Securities, each Guarantor hereby promises to and will, upon receipt of
written demand by the Trustee, pay, or cause to be paid, in cash, to the Holders
or the Trustee an amount equal to the sum of (i) the unpaid principal amount of
such obligations, (ii) accrued and unpaid interest on such obligations (but only
to the extent not prohibited by law) and (iii) all other monetary obligations of
the Company to the Holders and the Trustee.

          Each Guarantor agrees that it shall not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed
hereby until payment in full of all such obligations.  Each Guarantor further
agrees that, as between it, on the one hand, and the Holders and the Trustee, on
the other hand, (x) the maturity of the obligations guaranteed hereby may be
accelerated as provided in Article IV for the purposes of such Guarantor's
Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed hereby,
and (y) in the event of any declaration of acceleration of such obligations as
provided in Article IV, such obligations (whether or not due and payable) shall
forthwith become due and payable by the Guarantor for the purposes of this
Section.

          Each Guarantor also agrees to pay any and all costs and expenses
(including reasonable counsels' fees and expenses) incurred by the Trustee or
any Holder of a Security in enforcing any rights under this section with respect
to such Guarantor.

          To further evidence its Subsidiary Guarantee to the Holders, each
Guarantor hereby agrees to execute its Subsidiary Guarantee in substantially the
form set forth in Exhibit A and B hereto to be endorsed on each Security ordered
to be authenticated and delivered by the Trustee.  Each Guarantor hereby agrees
that its Subsidiary Guarantee set forth in this Section 10.1 shall remain in
full force and effect notwithstanding any failure to endorse on each Security a
notation of its Subsidiary Guarantee.  The Subsidiary Guarantee shall be signed
on behalf of each Guarantor by its Chairman of the Board, any Vice Chairman of
the Board, its Chief Executive Officer, its President, any executive vice
president, any senior vice president, its Controller, Treasurer, or any
Assistant Treasurer or its Secretary or any Assistant

                                                                              62

Secretary or any authorized signatory prior to the authentication of the
Security on which it is endorsed, and the delivery of such Security by the
Trustee, after the authentication thereof hereunder, shall constitute due
delivery of the Subsidiary Guarantee on behalf of such Guarantor. Such signature
upon a Subsidiary Guarantee may be the manual or facsimile signature of such
officer and may be imprinted or otherwise reproduced on the Subsidiary
Guarantee, and in case such officer who shall have signed the Subsidiary
Guarantee shall cease to be such officer before the Security on which the
Subsidiary Guarantee is endorsed shall have been authenticated and delivered by
the Trustee or disposed of by the Company, such Security nevertheless may be
authenticated and delivered or disposed of as though the Person who signed the
Subsidiary Guarantee had not ceased to be such officer of such Guarantor.

          SECTION 10.2  Limitation on Liability.  Any term or provision of this
                        -----------------------                                
Indenture to the contrary notwithstanding, the maximum, aggregate amount of the
obligations guaranteed hereunder by any Guarantor shall not exceed the maximum
amount that can, after giving effect to all other contingent and fixed
liabilities of such Guarantor be hereby guaranteed without rendering this
Indenture, as it relates to such Guarantor, voidable under applicable law
relating to fraudulent conveyance or fraudulent transfer or similar laws
affecting the rights of creditors generally.

          SECTION 10.3  Successors and Assigns.  This Article X shall be binding
                        ----------------------                                  
upon each Guarantor and its respective successors and assigns and shall enure to
the benefit of the successors and assigns of the Trustee and the Holders and, in
the event of any transfer or assignment of rights by any Holder or the Trustee,
the rights and privileges conferred upon that party in this Indenture and in the
Securities shall automatically extend to and be vested in such transferee or
assignee, all subject to the terms and conditions of this Indenture.

          SECTION 10.4  No Waiver.  Neither a failure nor a delay on the part of
                        ---------                                               
either the Trustee or the Holders in exercising any right, power or privilege
under this Article X shall operate as a waiver thereof, nor shall a single or
partial exercise thereof preclude any other or further exercise of any right,
power or privilege.  The rights, remedies and benefits of the trustee and the
Holders herein expressly specified are cumulative and not exclusive of any other
rights, remedies or benefits which either may have under this Article X at law,
in equity, by statute or otherwise.

          SECTION 10.5  Modification.  No modification, amendment or waiver of
                        ------------                                          
any provision of this Article X, nor the consent to any departure by any
Guarantor therefrom, shall in any event be effective unless the same shall be in
writing and signed by the Trustee, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given.  No
notice to or demand on any Guarantor in any case shall entitle such Guarantor to
any other or further notice or demand in the same, similar or other
circumstance.

          SECTION 10.6  Release.  If at any time shares of the Capital Stock of
                        -------                                                
any Guarantor shall be sold in a transaction the Net Cash Proceeds of which are
applied in accordance with the provisions of Section 3.12 which results in such
Guarantor no longer

constituting a Subsidiary, the Trustee is hereby authorized and directed to
execute and deliver a release of such Guarantor from its obligations and
liabilities under this Article X upon receipt by the Trustee of reasonable
evidence of compliance with the requirements of this Section 10.6.


                                   ARTICLE XI

                            MISCELLANEOUS PROVISIONS
                            ------------------------

          SECTION 11.1  Incorporators, Stockholders, Officers and Directors of
                        ------------------------------------------------------
Company Exempt from Individual Liability.  No recourse under or upon any
- ----------------------------------------                                
obligation, covenant or agreement contained in this Indenture, or in any
Security, or because of any indebtedness evidenced thereby, shall be had against
any incorporator, as such or against any past, present or future stockholder,
officer or director, as such, of the Company or of any successor, either
directly or through the Company or any successor, under any rule of law, statute
or constitutional provision or by the enforcement of any assessment or by any
legal or equitable proceeding or otherwise, all such liability being expressly
waived and released by the acceptance of the Securities by the holders thereof
and as part of the consideration for the issue of the Securities.

          SECTION 11.2  Provisions of Indenture for the Sole Benefit of Parties
                        -------------------------------------------------------
and Securityholders.  Nothing in this Indenture or in the Securities, expressed
- -------------------                                                            
or implied, shall give or be construed to give to any person, firm or
corporation, other than the parties hereto and their successors and the holders
of the Securities, any legal or equitable right, remedy or claim under this
Indenture or under any covenant or provision herein contained, all such
covenants and provisions being for the sole benefit of the parties hereto and
their successors and of the holders of the Securities.

          SECTION 11.3  Successors and Assigns of Company Bound by Indenture.
                        ----------------------------------------------------  
All the covenants, stipulations, promises and agreements in this Indenture
contained by or in behalf of the Company shall bind its successors and assigns,
whether so expressed or not.

          SECTION 11.4  Notices and Demands on Company, Trustee and
                        -------------------------------------------
Securityholders.  Any notice or demand which by any provision of this Indenture
- ---------------                                                                
is required or permitted to be given or served by the Trustee or by the holders
of Securities to or on the Company may be given or served by being deposited
postage prepaid, first-class mail (except as otherwise specifically provided
herein) addressed (until another address of the Company is filed by the Company
with the Trustee) to Schein Pharmaceutical, Inc., 100 Campus Drive, Florham
Park, NJ 07932, Chief Financial Officer with a copy to the General Counsel.  Any
notice, direction, request or demand by the Company or any Securityholder to or
upon the Trustee shall be deemed to have been sufficiently given or made, for
all purposes, if given or made at the Corporate Trust Office.

          Where this Indenture provides for notice to Holders, such notice shall
be sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, 
<PAGE>
 
                                                                              64

first-class postage prepaid, to each Holder entitled thereto, at his last
address as it appears in the Security register. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

          In case, by reason of the suspension of or irregularities in regular
mail service, it shall be impracticable to mail notice to the Company and
Securityholders when such notice is required to be given pursuant to any
provision of this Indenture, then any manner of giving such notice as shall be
satisfactory to the Trustee shall be deemed to be a sufficient giving of such
notice.

          SECTION 11.5  Officers' Certificates and Opinions of Counsel;
                        -----------------------------------------------
Statements to Be Contained Therein.  Upon any application or demand by the
- ----------------------------------                                        
Company to the Trustee to take any action under any of the provisions of this
Indenture, the Company shall furnish to the Trustee an Officers' Certificate
stating that all conditions precedent provided for in this Indenture relating to
the proposed action have been complied with and an Opinion of Counsel stating
that in the opinion of such counsel all such conditions precedent have been
complied with, except that in the case of any such application or demand as to
which the furnishing of such documents is specifically required by any provision
of this Indenture relating to such particular application or demand, no
additional certificate or opinion need be furnished.

          Each certificate or opinion provided for in this Indenture and
delivered to the Trustee with respect to compliance with a condition or covenant
provided for in this Indenture shall include (a) a statement that the person
making such certificate or opinion has read such covenant or condition, (b) a
brief statement as to the nature and scope of the examination or investigation
upon which the statements or opinions contained in such certificate or opinion
are based, (c) a statement that, in the opinion of such person, he has made such
examination or investigation as is necessary to enable him to express an
informed opinion as to whether or not such covenant or condition has been
complied with and (d) a statement as to whether or not, in the opinion of such
person, such condition or covenant has been complied with.

          Any certificate, statement or opinion of an officer of the Company may
be based, insofar as it relates to legal matters, upon a certificate or opinion
of or representations by counsel, unless such officer knows that the certificate
or opinion or representations with respect to the matters upon which his
certificate, statement or opinion may be based as aforesaid are erroneous, or in
the exercise of reasonable care should know that the same are erroneous.  Any
certificate, statement or opinion of counsel may be based, insofar as it relates
to factual matters and information in the possession of the Company, upon the
certificate, statement or opinion of or representations by an officer or
officers of the Company, unless such counsel knows that the certificate,
statement or opinion or representations with respect to 
<PAGE>
 
                                                                              65

the matters upon which his certificate, statement or opinion may be based as
aforesaid are erroneous, or in the exercise of reasonable care should know that
the same are erroneous.

          Any certificate, statement or opinion of an officer of the Company or
of counsel may be based, insofar as it relates to accounting matters, upon a
certificate or opinion of or representations by an accountant or firm of

          SECTION 12.1  Right of Optional Redemption; Prices.  At any time, the
                        ------------------------------------                   
Company may redeem, in whole or in part, the Securities on not less than 30 nor

provision of this Indenture, shall be made in accordance with such provision and
this Article.

          SECTION 12.3  Election to Redeem; Notice to Trustee.  The election of
                        -------------------------------------

by a resolution of the Board of Directors.  In case of any redemption at the
election of the Company, the Company shall, at least 60 days prior to the
redemption date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such redemption date and of
the principal amount of Securities to be redeemed and shall deliver to the
Trustee such documentation and records as shall enable the Trustee to select the
Securities to be redeemed pursuant to Section 12.4(e).

          SECTION 12.4  Notice of Redemption; Partial Redemptions. (a)  Notice
                        -----------------------------------------

shall be given by mailing notice of such redemption by first class mail, postage
prepaid, at least 30 days and not more than 60 days prior to the date fixed for
redemption to such holders of Securities at their last addresses as they shall
appear upon the registry books. Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not
the holder receives the notice. Failure to give notice by mail, or any defect in
the notice to the holder of any Security designated for redemption as a whole or
in part shall not affect the validity of the proceedings for the redemption of
any other Security.

          (b)  The notice of redemption to each such holder shall identify the
Security, including CUSIP numbers, and shall specify the principal amount of
each Security held by such holder to be redeemed, the date fixed for redemption,
the redemption price, the place or places of payment, that payment will be made
upon presentation and surrender of such Securities, that interest accrued to the
date fixed for redemption will be paid as specified in said notice and that on
and after said date interest thereon or on the portions thereof to be redeemed
will cease to accrue.  In case any Security is to be redeemed in part only the
notice of redemption shall state the portion of the principal amount thereof to
be redeemed and shall state that on and after the date fixed for redemption,
upon surrender of such Security, a new

Security or Securities in principal amount equal to the unredeemed portion
thereof will be issued.

          (c)  The notice of redemption of Securities to be redeemed at the
option of the Company shall be given by the Company or, at the Company's
request, by the Trustee in the name and at the expense of the Company.

          (d)  At least one business day prior to the redemption date specified
in the notice of redemption given as provided in this Section, the Company will
deposit with the Trustee or with one or more paying agents (or, if the Company
is acting as its own paying agent, set aside, segregate and hold in trust as
provided in Section 3.4) an amount of money sufficient to redeem on the
redemption date all the Securities so called for redemption at the appropriate
redemption price, together with accrued interest to the date fixed for
redemption.  If less than all the outstanding Securities are to be redeemed the
Company will deliver to the Trustee at least 60 days prior to the date fixed for
redemption an Officers' Certificate stating the aggregate principal amount of
Securities to be redeemed.

          (e)  The Trustee shall select the Securities or portions thereof,
either pro rata, by lot or by such method as the Trustee shall deem fair and
reasonable, securities to be redeemed in whole or in part.  Securities may be
redeemed in part in multiples of $1,000 or an integral multiple thereof.  The
Trustee shall, upon the request of the Company, promptly notify the Company in
writing of the Securities selected for redemption and, in the case of any
Securities selected for partial redemption, the principal amount thereof to be
redeemed.  For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

          SECTION 12.5  Payment of Securities Called for Redemption.  (a)  If
                        -------------------------------------------          
notice of redemption has been given as above provided, the Securities or
portions of Securities specified in such notice shall become due and payable on
the date and at the place stated in such notice at the applicable redemption
price, together with interest accrued to the date fixed for redemption, and on
and after said date (unless the Company shall default in the payment of such
Securities at the redemption price, together with interest accrued to said date)
interest on the Securities or portions of Securities so called for redemption
shall cease to accrue and, except as provided in Sections 5.5 and 9.6, such
Securities shall cease from and after the date fixed for redemption to be
entitled to any benefit or security under this Indenture, and the holders
thereof shall have no right in respect of such Securities except the right to
receive the redemption price thereof and unpaid interest to the date fixed for
redemption.  On presentation and surrender of such Securities at a place of
payment specified in said notice, said Securities or the specified portions
thereof shall be paid and redeemed by the Company at the applicable redemption
price, together with interest accrued thereon to the date fixed for redemption;
provided that any quarterly payment of interest becoming due on the date fixed

for redemption shall be payable to the holders of such Securities registered as
such on the relevant record date subject to the terms and provisions of Section
2.4.

          (b)  If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal shall, until paid or duly
provided for, bear interest from the date fixed for redemption at the rate borne
by the Security.

          (c)  Upon presentation of any Security redeemed in part only, the
Company shall execute and the Trustee shall authenticate and deliver to or on
the order of the holder thereof, at the expense of the Company, a new Security
or Securities, of authorized denominations, in principal amount equal to the
unredeemed portion of the Security so presented.

interest at a rate per annum equal to the Applicable LIBOR Rate (as defined
herein).

          The Company shall pay interest quarterly on January 15, April 15, July
15, and October 15, of each year, commencing with January 15, 1998.  Interest on
the Securities will accrue from the most recent interest payment date to which

basis by multiplying the principal amount of the Securities then outstanding by
the Applicable LIBOR Rate, and multiplying such product by the LIBOR Fraction
(as defined herein).

hereof.  Such further provisions shall for all purposes have the same effect as
though fully set forth at this place.

of authentication hereon shall have been duly signed by the Trustee acting under
the Indenture.

State of New York, and for all purposes shall be construed in accordance with
the laws of the State of New York, without giving effect to applicable
principles of conflicts of law to the extent that the application of the laws of
another jurisdiction would be required thereby.

                       [FORM OF REVERSE OF INITIAL NOTE]

                          SCHEIN PHARMACEUTICAL, INC.
                      Senior Floating Rate Notes due 2004

          This Security is one of a duly authorized issue of debt securities of
the Company, limited to the aggregate principal amount of $___________ (except
as otherwise provided in the Indenture mentioned below), issued or to be issued
pursuant to an Indenture dated as of December 24, 1997 (the "Indenture"), duly
executed and delivered by the Company and the Guarantors to the Trustee (herein
called the "Trustee").  The terms of the Securities include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as in effect on the date of the Indenture (the "Trust
Indenture Act").  Capitalized terms used herein and not defined have the
meanings ascribed thereto in the Indenture.  The Securities are subject to all
such terms and Securityholders are referred to the Indenture and the Trust
Indenture Act for a statement of those terms.  The terms of the Indenture shall
govern any inconsistencies between the Indenture and the Securities.

          This Security is one of the Initial Notes referred to in the
Indenture.  The Securities include the Initial Notes and the Exchange Notes
issued in exchange for the Initial Notes pursuant to the Indenture and the
Registration Rights Agreement.  The Initial Notes and the Exchange Notes are
treated as a single class of securities under the Indenture.

          Each Guarantor has jointly and severally guaranteed, pursuant to
Article X of the Indenture, the due and punctual payment of the principal of,
premium (if any) and interest on the Securities and all other amounts payable by
the Company under the Indenture and the Securities when and as the same shall be
due and payable, whether at maturity, by acceleration or otherwise, according to
the terms of the Securities and the Indenture.

          The Securities will bear interest at the Applicable LIBOR Rate.
"Applicable LIBOR Rate" means, for each quarterly period during which any
Security is outstanding subsequent to the initial quarterly period, 300 basis
points over the rate determined by the Company (notice of such rate to be sent
to the Trustee by the Company on the date of determination thereof) equal to the
average (rounded upwards, if necessary, to the nearest 1/16 of 1%) of the
offered rates for deposits in U.S. dollars for a period of three months, as set
forth on the Reuters Screen LIBO Page as of 11:00 a.m., London time, on the
Interest Rate Determination Date for such quarterly period; provided, however,
that if only one such offered rate appears on the Reuters Screen LIBO Page, the
Applicable LIBOR Rate for such quarterly period will mean such offered rate.  If
such rate is not available at 11:00 a.m., London time, on the Interest Rate
Determination Date for such quarterly period, then the Applicable LIBOR Rate for
such quarterly period will mean the arithmetic mean (rounded upwards, if
necessary, to the nearest 1/16 of 1%) of the interest rates per annum at which
deposits in amounts equal to US$1 million are offered by the Reference Banks to
leading banks in the London interbank market for a period of three months as of
11:00 a.m., London time, on the Interest Rate Determination Date for such
quarterly period. If on any Interest Rate Determination Date, at least two of
the Reference Banks provide such offered quotations, then the Applicable LIBOR
Rate for such quarterly period will be determined in accordance with the
preceding sentence

                                      A-5
<PAGE>
 
on the basis of the offered quotation of those Reference Banks providing such
quotations; provided, however, that if fewer than two of the Reference Banks are
so quoting such interest rates as mentioned above, the Applicable LIBOR Rate for
such quarterly period shall be deemed to be the applicable LIBOR Rate for the
next preceding quarterly period and in the case of the quarterly period next
succeeding the initial quarterly period, the Applicable LIBOR Rate shall be
8.9375%. Notwithstanding the foregoing, the Applicable LIBOR Rate for the
initial quarterly period shall be 8.9375%. "Interest Rate Determination Date"
means, with respect to each quarterly period, the second London Banking Day
prior to the first day of such quarterly period. "London Banking Day" means any
day in which dealings in United States dollars are transacted or, with respect
to any future date, are expected to be transacted in the London interbank
market. "LIBOR Fraction" means the actual number of days in the quarterly period
divided by 360; provided, however, that the number of days in each quarterly
period shall be calculated by including the first day of such quarterly period
and excluding the last. "Quarterly period" means the period from and including a
scheduled payment date (or December 24, 1997, in the case of the initial
quarterly period) through the day next preceding the following scheduled
interest payment date. "Reference Banks" means each of Societe Generale, London
Branch, The Chase Manhattan Bank, London Branch, Deutsche Bank, London Branch
and Rabobank Nederland, London Branch, and any such replacement bank thereof as
listed on the Reuters Screen LIBO Page and their respective successors, and if
any such banks are not at the applicable time providing interest rates as
contemplated within the definition of the "Applicable LIBOR Rate," Reference
Banks shall mean the remaining bank or banks so providing such rates. In the
event that less than two of such banks are providing such rates, the Company
shall use reasonable efforts to appoint additional Reference Banks so that there
are at least two such banks providing such rates; provided, however, that such
banks appointed by the Company shall be London offices of leading banks engaged
in the London interbank market. "Reuters Screen LIBO Page" means the display
deigned as page "LIBO" on the Reuter Monitor Money Rates Service (or such other
page as may replace the LIBO page on that service for the purpose of displaying
London Interbank Offered Rates of leading banks).

          If the date due for payment of interest on or principal of the
Securities or the date fixed for redemption of any Security shall not be a
Business Day, then payment of interest or principal need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the date of maturity or the date fixed for redemption,
and no interest shall accrue for the period after such date.

          In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all the Securities may be declared
due and payable, in the manner and with the effect, and subject to the
conditions, provided in the Indenture.  The Indenture provides that in certain
events such declaration and its consequences may be waived by the holders of a
majority in aggregate principal amount of the Securities then outstanding and
that, prior to any such declaration, such holders may waive any past default
under the Indenture and its consequences except a default in the payment of
principal of or premium, if any, or interest on any of the Securities.  Any such
consent or waiver by the holder of this Security (unless revoked as provided in
the Indenture) shall be conclusive and binding upon such holder and upon all
future holders and owners of this Security and any Security which

                                      A-6
<PAGE>
 
may be issued in exchange or substitution herefor, whether or not any notation
thereof is made upon this Security or such other Securities.

          Subject to certain exceptions set forth in the Indenture, the
Indenture or the Securities may be amended without notice to any Holder but with
the written consent of the Holders of at least a majority in outstanding
principal amount of the Securities; provided that no such amendment shall (a)
                                    --------                                 
reduce the amount of Securities whose Holders must consent to an amendment; (b)
reduce the rate of or extend the time for payment of interest on any Security;
(c) reduce the principal of or extend the Stated Maturity of any Security; (d)
reduce the premium payable upon the redemption or repurchase of any Security or
change the time at which any Security may or shall be redeemed or repurchased in
accordance with this Indenture; (e) make any Security payable in money other
than that stated in the Security; (f) modify or affect in any manner adverse to
the Holders the terms and conditions of the obligation of the Company for the
due and punctual payment of the principal of or interest on Securities; or (g)
make any change in Section 4.4 or 4.7 of the Indenture or the second sentence of
Section 7.2 of the Indenture, without the consent of each holder of Securities
affected by such amendment.

          No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligations of the Company or the
Guarantors, which are absolute and unconditional, to pay the principal of and
premium, if any, and interest on this Security at the place, times, and rate,
and in the currency, herein prescribed.

          The Securities are issuable only as registered Securities without
coupons in denominations of $1,000 and any integral multiple thereof.

          The Securities may be exchanged for a like aggregate principal amount
of Securities of other authorized denominations in accordance with and subject
to the limitations provided in the Indenture.

          Upon due presentment for registration of transfer of this Security, a
new Security or Securities of authorized denominations, for a like aggregate
principal amount, will be issued to the transferee as provided in the Indenture.
No service charge shall be made for any such transfer, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto.

          At any time, the Company may redeem, in whole or in part, the
Securities on not less than 30 nor more than 60 days' prior notice at a
redemption price equal to 103.00% of the aggregate principal amount thereof if
redeemed prior to January 15, 1999, 101.50% of the aggregate principal amount
thereof if redeemed on or after January 15, 1999 and prior to January 15, 2000,
100.75% of the aggregate principal amount thereof if redeemed on or after
January 15, 2000 and prior to January 15, 2001, and 100% of the aggregate
principal amount thereof if redeemed on or after January 15, 2001, plus, in each
case, accrued interest thereon to, but excluding, the date of redemption.

          Subject to payment by the Company of a sum sufficient to pay the
amount due on redemption, interest on this Security (or portion hereof if this
Security is redeemed in part)

                                      A-7
<PAGE>
 
shall cease to accrue upon the date duly fixed for redemption of this Security
(or portion hereof if this Security is redeemed in part).

          The election of the Company to redeem any Securities pursuant to
Section 12.1 of the Indenture shall be evidenced by a resolution of the Board of
Directors.  In case of any redemption at the election of the Company, the
Company shall, at least 60 days prior to the redemption date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such redemption date and of the principal amount of Securities to
be redeemed and shall deliver to the Trustee such documentation and records as
shall enable the Trustee to select the Securities to be redeemed pursuant to
Section 12.4(e) of the Indenture.

          In the event of a Change of Control, the Company will make a Change of
Control Offer to purchase all of the Securities outstanding at a price equal to
101% of the principal amount of the Securities to be repurchased plus accrued
and unpaid interest thereon to the date of purchase, pursuant to an offer made
in conformity with the procedures set forth in Section 3.15 of the Indenture.

          In the event of certain Asset Dispositions, subject to certain
conditions, the Company will make an Offer to purchase an aggregate principal
amount of Securities outstanding equal to the amount of Net Available Cash at a
price equal to 100% of the principal amount of the Securities to be repurchased
plus accrued and unpaid interest thereon to the date of purchase.

          The Company, the Trustee, and any authorized agent of the Company or
the Trustee may deem and treat the registered Holder hereof as the absolute
owner of this Security (whether or not this Security shall be overdue and
notwithstanding any notation of ownership or other writing hereon made by anyone
other than the Company or the Trustee or any authorized agent of the Company or
the Trustee), for the purpose of receiving payment of, or on account of, the
principal hereof and premium, if any, and, subject to the provisions on the face
hereof, interest hereon and for all other purposes, and neither the Company nor
the Trustee nor any authorized agent of the Company or the Trustee shall be
affected by any notice to the contrary.  So long as the Depository, or its
nominee, is the registered holder of the Restricted Global Security for the
Initial Notes, the Depository, or its nominee, will be considered the absolute
owner of the Initial Notes represented by the Restricted Global Security for all
purposes under the Indenture and this Security.  Owners of beneficial interests
in the Restricted Global Security will not be considered the owners or Holders
of any Securities.

          The Securities are subject to defeasance as described in the
Indenture.

          No recourse shall be had for the payment of the principal of and
premium, if any, or the interest on this Security, for any claim based hereon,
or otherwise in respect hereof, or based on or in respect of the Indenture or
any indenture supplemental thereto, against any incorporator, shareholder,
officer or director, as such, past, present or future, of the Company or of any
successor corporation, either directly or through the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law or by
the

                                      A-8
<PAGE>
 
enforcement of any assessment or penalty or otherwise, all such liability being,
by the acceptance hereof and as part of the consideration for the issue hereof,
expressly waived and released.

                      Senior Floating Rate Notes due 2004

          Schein Pharmaceutical, Inc., a Delaware corporation (the "Company"),
for value received hereby promises to pay to ______________________ or its
registered assigns the principal sum of _________________ Dollars on December
24, 2004, in such coin or currency of the United States of America as at the
time of payment shall be legal tender for the payment of public and private
debts, and to pay interest at a rate per annum equal to the Applicable LIBOR
Rate (as defined herein).

          The Company shall pay interest quarterly on January 15, April 15, July
15, and October 15, of each year, commencing with January 15, 1998.  Interest on
the Securities will accrue from the most recent interest payment date to which
interest on the Securities has been paid or duly provided for, or if no interest
has been paid or duly provided for on the Securities, from December 24, 1997,
until payment of said principal sum has been made or duly provided for.  The
interest so payable on any January 15, April 15, July 15 and October 15, will,
except as otherwise provided in the Indenture referred to on the reverse hereof,
be paid to the person in whose name this Security is registered at the close of
business on the December 31, March 31, June 30, and September 30 preceding such
January 15, April 15, July 15 and October 15, whether or not such day is a
business day; provided that interest may be paid, at the option of the Company,
              --------                                                         
by mailing a check therefor payable to the registered holder entitled thereto at
his last address as it appears on the Security register.

          Interest on this Security will accrue at a rate equal to the
Applicable LIBOR Rate (as defined herein) and will be calculated on a formula
basis by multiplying the principal amount of the Securities then outstanding by
the Applicable LIBOR Rate, and multiplying such product by the LIBOR Fraction
(as defined herein).

          Reference is made to the further provisions set forth on the reverse
hereof.  Such further provisions shall for all purposes have the same effect as
though fully set forth at this place.

          This Security shall not be valid or obligatory until the certificate
of authentication hereon shall have been duly signed by the Trustee acting under
the Indenture.

          This Security shall be deemed to be contract under the laws of the
State of New York, and for all purposes shall be construed in accordance with
the laws of the State of New York, without giving effect to applicable
principles of conflicts of law to the extent that the application of the laws of
another jurisdiction would be required thereby.

          IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed.

                       [FORM OF REVERSE OF EXCHANGE NOTE]

                          SCHEIN PHARMACEUTICAL, INC.
                      Senior Floating Rate Notes due 2004

          This Security is one of a duly authorized issue of debt securities of
the Company, limited to the aggregate principal amount of $___________ (except
as otherwise provided in the Indenture mentioned below), issued or to be issued
pursuant to an Indenture dated as of December 24, 1997 (the "Indenture"), duly
executed and delivered by the Company and the Guarantors to the Trustee (herein
called the "Trustee").  The terms of the Securities include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as in effect on the date of the Indenture (the "Trust
Indenture Act").  Capitalized terms used herein and not defined have the
meanings ascribed thereto in the Indenture.  The Securities are subject to all
such terms and Securityholders are referred to the Indenture and the Trust
Indenture Act for a statement of those terms.  The terms of the Indenture shall
govern any inconsistencies between the Indenture and the Securities.

          This Security is one of the Exchange Notes referred to in the
Indenture.

          Each Guarantor has jointly and severally guaranteed, pursuant to
Article X of the Indenture, the due and punctual payment of the principal of,
premium (if any) and interest on the Securities and all other amounts payable by
the Company under the Indenture and the Securities when and as the same shall be
due and payable, whether at maturity, by acceleration or otherwise, according to
the terms of the Securities and the Indenture.

          The Securities will bear interest at the Applicable LIBOR Rate.
"Applicable LIBOR Rate" means, for each quarterly period during which any
Security is outstanding subsequent to the initial quarterly period, 300 basis
points over the rate determined by the Company (notice of such rate to be sent
to the Trustee by the Company on the date of determination thereof) equal to the
average (rounded upwards, if necessary, to the nearest 1/16 of 1%) of the
offered rates for deposits in U.S. dollars for a period of three months, as set
forth on the Reuters Screen LIBO Page as of 11:00 a.m., London time, on the
Interest Rate Determination Date for such quarterly period; provided, however,
that if only one such offered rate appears on the Reuters Screen LIBO Page, the
Applicable LIBOR Rate for such quarterly period will mean such offered rate.  If
such rate is not available at 11:00 a.m., London time, on the Interest Rate
Determination Date for such quarterly period, then the Applicable LIBOR Rate for
such quarterly period will mean the arithmetic mean (rounded upwards, if
necessary, to the nearest 1/16 of 1%) of the interest rates per annum at which
deposits in amounts equal to US$1 million are offered by the Reference Banks to
leading banks in the London interbank market for a period of three months as of
11:00 a.m., London time, on the Interest Rate Determination Date for such
quarterly period.  If on any Interest Rate Determination Date, at least two of
the Reference Banks provide such offered quotations, then the Applicable LIBOR
Rate for such quarterly period will be determined in accordance with the
preceding sentence

                                      B-4
<PAGE>
 
on the basis of the offered quotation of those Reference Banks providing such
quotations; provided, however, that if fewer than two of the Reference Banks are
so quoting such interest rates as mentioned above, the Applicable LIBOR Rate for
such quarterly period shall be deemed to be the applicable LIBOR Rate for the
next preceding quarterly period and in the case of the quarterly period next
succeeding the initial quarterly period, the Applicable LIBOR Rate shall be
8.9375%. Notwithstanding the foregoing, the Applicable LIBOR Rate for the
initial quarterly period shall be 8.9375%. "Interest Rate Determination Date"
means, with respect to each quarterly period, the second London Banking Day
prior to the first day of such quarterly period. "London Banking Day" means any
day in which dealings in United States dollars are transacted or, with respect
to any future date, are expected to be transacted in the London interbank
market. "LIBOR Fraction" means the actual number of days in the quarterly period
divided by 360; provided, however, that the number of days in each quarterly
period shall be calculated by including the first day of such quarterly period
and excluding the last. "quarterly period" means the period from and including a
scheduled payment date (or December 24, 1997, in the case of the initial
quarterly period) through the day next preceding the following scheduled
interest payment date. "Reference Banks" means each of Societe Generale, London
Branch, The Chase Manhattan Bank, London Branch, Deutsche Bank, London Branch
and Rabobank Nederland, London Branch, and any such replacement bank thereof as
listed on the Reuters Screen LIBO Page and their respective successors, and if
any such banks are not at the applicable time providing interest rates as
contemplated within the definition of the "Applicable LIBOR Rate," Reference
Banks shall mean the remaining bank or banks so providing such rates. In the
event that less than two of such banks are providing such rates, the Company
shall use reasonable efforts to appoint additional Reference Banks so that there
are at least two such banks providing such rates; provided, however, that such
banks appointed by the Company shall be London offices of leading banks engaged
in the London interbank market. "Reuters Screen LIBO Page" means the display
deigned as page "LIBO" on the Reuter Monitor Money Rates Service (or such other
page as may replace the LIBO page on that service for the purpose of displaying
London Interbank Offered Rates of leading banks).

          If the date due for payment of interest on or principal of the
securities or the date fixed for redemption of any Security shall not be a
Business Day,  then payment of interest or principal need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the date of maturity or the date fixed for redemption,
and no interest shall accrue for the period after such date.

          In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all the Securities may be declared
due and payable, in the manner and with the effect, and subject to the
conditions, provided in the Indenture.  The Indenture provides that in certain
events such declaration and its consequences may be waived by the holders of a
majority in aggregate principal amount of the Securities then outstanding and
that, prior to any such declaration, such holders may waive any past default
under the Indenture and its consequences except a default in the payment of
principal of or premium, if any, or interest on any of the Securities. Any such
consent or waiver by the holder of this

                                      B-5
<PAGE>
 
Security (unless revoked as provided in the Indenture) shall be conclusive and
binding upon such holder and upon all future holders and owners of this Security
and any Security which may be issued in exchange or substitution herefor,
whether or not any notation thereof is made upon this Security or such other
Securities.

          Subject to certain exceptions set forth in the Indenture, the
Indenture or the Securities may be amended without notice to any Holder but with
the written consent of the Holders of at least a majority in outstanding
principal amount of the Securities; provided that no such amendment shall (a)
                                    --------                                 
reduce the amount of Securities whose Holders must consent to an amendment; (b)
reduce the rate of or extend the time for payment of interest on any Security;
(c) reduce the principal of or extend the Stated Maturity of any Security; (d)
reduce the premium payable upon the redemption or repurchase of any Security or
change the time at which any Security may or shall be redeemed or repurchased in
accordance with this Indenture; (e) make any Security payable in money other
than that stated in the Security; (f) modify or affect in any manner adverse to
the Holders the terms and conditions of the obligation of the Company for the
due and punctual payment of the principal of or interest on Securities; or (g)
make any change in Section 4.4 or 4.7 of the Indenture or the second sentence of
Section 7.2 of the Indenture, without the consent of each holder of Securities
affected by such amendment.

          No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligations of the Company or the
Guarantors, which are absolute and unconditional, to pay the principal of and
premium, if any, and interest on this Security at the place, times, and rate,
and in the currency, herein prescribed.

          The Securities are issuable only as registered Securities without
coupons in denominations of $1,000 and any integral multiple thereof.

          The Securities may be exchanged for a like aggregate principal amount
of Securities of other authorized denominations in accordance with and subject
to the limitations provided in the Indenture.

          Upon due presentment for registration of transfer of this Security, a
new Security or Securities of authorized denominations, for a like aggregate
principal amount, will be issued to the transferee as provided in the Indenture.
No service charge shall be made for any such transfer, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto.

          At any time, the Company may redeem, in whole or in part, the
Securities on not less than 30 nor more than 60 days' prior notice at a
redemption price equal to 103.00% of the aggregate principal amount thereof if
redeemed prior to January 15, 1999, 101.50% of the aggregate principal amount
thereof if redeemed on or after January 15, 1999 and prior to January 15, 2000,
100.75% of the aggregate principal amount 

                                      B-6
<PAGE>
 
thereof if redeemed on or after January 15, 2000 and prior to January 15, 2001
and 100% of the aggregate principal amount thereof if redeemed on or after
January 15, 2001, plus, in each case, accrued interest thereon to, but
excluding, the date of redemption.

          Subject to payment by the Company of a sum sufficient to pay the
amount due on redemption, interest on this Security (or portion hereof if this
Security is redeemed in part) shall cease to accrue upon the date duly fixed for
redemption of this Security (or portion hereof if this Security is redeemed in
part).

          The election of the Company to redeem any Securities pursuant to
Section 12.1 of the Indenture shall be evidenced by a resolution of the Board of
Directors.  In case of any redemption at the election of the Company, the
Company shall, at least 60 days prior to the redemption date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such redemption date and of the principal amount of Securities to
be redeemed and shall deliver to the Trustee such documentation and records as
shall enable the Trustee to select the Securities to be redeemed pursuant to
Section 12.4(e) of the Indenture.

          In the event of a Change of Control, the Company will make a Change of
Control Offer to purchase all of the Securities outstanding at a price equal to
101% of the principal amount of the Securities to be repurchased plus accrued
and unpaid interest thereon to the date of purchase, pursuant to an offer made
in conformity with the procedures set forth in Section 3.15 of the Indenture.

          In the event of certain Asset Dispositions, subject to certain
conditions, the Company will make an Offer to purchase an aggregate principal
amount of Securities outstanding equal to the amount of Net Available Cash at a
price equal to 100% of the principal amount of the Securities to be repurchased
plus accrued and unpaid interest thereon to the date of purchase.

          The Company, the Trustee, and any authorized agent of the Company or
the Trustee may deem and treat the registered Holder hereof as the absolute
owner of this Security (whether or not this Security shall be overdue and
notwithstanding any notation of ownership or other writing hereon made by anyone
other than the Company or the Trustee or any authorized agent of the Company or
the Trustee), for the purpose of receiving payment of, or on account of, the
principal hereof and premium, if any, and, subject to the provisions on the face
hereof, interest hereon and for all other purposes, and neither the Company nor
the Trustee nor any authorized agent of the Company or the Trustee shall be
affected by any notice to the contrary.

          The Securities are subject to defeasance as described in the
Indenture.

          No recourse shall be had for the payment of the principal of and
premium, if any, or the interest on this Security, for any claim based hereon,
or otherwise in respect hereof, or based on or in respect of the Indenture or
any indenture supplemental thereto,

present or future, of the Company or of any successor corporation, either
directly or through the Company or any successor corporation, whether by virtue

assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issue hereof, expressly waived
and released.

to effect the transfer of the Securities to the undersigned.

          In connection with such request, and in respect of such Securities, we
confirm that:

          1.  We understand that the offer and sale of the Securities have not

     accordance with Rule 144A under the Securities Act to a "qualified

     the restrictions on transfer of the Securities (the form of which letter
     can be obtained from the Trustee), (D) outside the United States in
     accordance with Regulation S under the Securities Act (if available), (E)
     pursuant to the exemption from registration provided by Rule 144 under the
     Securities Act (if available), or (F) pursuant to an effective registration
     statement under the Securities Act.

          2.  We understand that, on any proposed resale of Securities, we will
     be required to furnish to the Trustee and the Company such certification,
     legal opinions and other information as the Trustee and the Company may
     reasonably require to confirm that the proposed sale complies with the
     foregoing restrictions.

          3.  We are an institutional "accredited investor" (as defined in Rule
     501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and
     have such knowledge and experience in financial and business matters as to
     be capable of evaluating the merits and risks of our investment in the
     Securities, and we and any accounts for which we are acting are each able
     to bear the economic risk of our or their investment, as the case may be.

          4.  We are a corporation, partnership or other entity or person having
     such knowledge and experience in financial and business matters as to be
     capable of evaluating the merits and risks of an investment in the

     Institutional Accredited Investor, able to bear the economic risk of
     investment in the Securities.

          5.  We are acquiring the Securities for our own account (or for
     accounts as to which we exercise sole investment discretion and have
     authority to make, and do make, the statements contained in this letter)
     and not with a view to any distribution of the Securities, subject,
     nevertheless, to the understanding that the disposition of our property
     shall at all times be and remain within our control.

          6.  We understand that (a) the Securities will be delivered to us in
     registered form only and that the certificate delivered to us in respect of
     the Securities will bear a legend substantially to the following effect:

               THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES
          SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,
          ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR
          TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH

          WITHIN THREE YEARS AFTER THE ORIGINAL ISSUANCE OF THIS SECURITY,
          RESELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO SCHEIN

          A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE
          SECURITIES ACT, (C) TO AN ACCREDITED INSTITUTION THAT, PRIOR TO SUCH
          TRANSFER, FURNISHES (OR HAS FURNISHED ON ITS BEHALF BY A U.S. BROKER-
          DEALER) TO THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN

          FROM THE TRUSTEE), (D) OUTSIDE THE UNITED STATES IN AN OFFSHORE
          TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT,
          (E) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144
          UNDER THE SECURITIES ACT (IF AVAILABLE), OR (F) PURSUANT TO AN
          EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT.  IN
          CONNECTION WITH ANY TRANSFER OF THIS SECURITY WITHIN THREE YEARS AFTER

          ACCREDITED INSTITUTION, THE HOLDER MUST, PRIOR TO SUCH TRANSFER,
          FURNISH TO THE TRUSTEE AND THE COMPANY SUCH CERTIFICATIONS, LEGAL
          OPINIONS OR OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY REQUIRE
          TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION
          FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
          REQUIREMENTS OF THE SECURITIES ACT.  AS USED HEREIN, THE TERMS
          "OFFSHORE TRANSACTION", "UNITED STATES" AND "U.S. PERSON" HAVE THE
          MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

          and (b) such certificates will be reissued without the foregoing
          legend only in the event of a disposition of the Securities in
          accordance with the provisions of Section 2.5 of the Indenture.

          7.  We agree that we will give to each person to whom we transfer
     Securities notice of any restrictions on transfer of Securities.

          8. We acknowledge that the Trustee will not be required to accept for

     the restrictions set forth herein have been complied with.

          9.  We acknowledge that the Company, the Trustee and others will rely
     upon the truth and accuracy of the foregoing acknowledgments,
     representations or agreements and agree that if any of the acknowledgments,
     representations or agreements deemed to have been made by our purchase of

               Senior Floating Rate Notes
               due 2004 (the "Securities")
               ---------------------------

Ladies and Gentlemen:

          This opinion is being furnished to you in connection with the sale by
__________________ (the "Transferor") to ____________________________ (the
"Purchaser") of $_____________ aggregate principal amount of _______ Senior
Floating Rate Notes due 2004 of Schein Pharmaceutical, Inc. (the "Securities").

          We have examined such documents and records as we have deemed
appropriate. In our examination of the foregoing, we have assumed the
authenticity of all documents, the genuineness of all signatures and the due
authorization, execution and delivery of the aforementioned by each of the
parties thereto.  We have further assumed the accuracy of the representations
contained in the documents set forth above made by the parties executing such
documents.  We have also assumed that the sale of the Securities to the
Transferor was exempt from the registration and prospectus delivery requirements
of the Securities Act of 1933, as amended (the "Securities Act").

          Based on the foregoing, we are of the opinion that the sale to the
Purchaser of the Securities does not require registration of such Securities
under the Securities Act.

                              Very truly yours,

a Registrable Security when (i) a registration statement covering such
Registrable Security has been declared effective by the Securities and Exchange
Commission (the "Commission") and it has been disposed of pursuant to such

all of the applicable conditions of Rule 144 (or any similar provisions then in
force) under the Securities Act are met.

     2.   Registered Exchange Offer.
          ------------------------- 

          (a) The Company shall prepare and, on or prior to 45 days after the
Issue Date, file with the Commission a registration statement on an appropriate
form under the Securities Act with respect to a proposed offer (the "Registered
Exchange Offer") to the Holders of the Notes to issue and deliver to such
Holders, in exchange for the Notes, a like principal amount of debt securities
of the Company identical in all material respects to the Notes (the "Exchange
Notes") and shall use commercially reasonable efforts to cause such registration
statement to become effective under the Securities Act as soon as practical
after filing and in any event within the earlier of (i) 90 days after the Issue
Date or (ii) 30 days after the consummation of the initial public offering of
the Company's common stock, par value $.01 per share (the "Common Stock").  Upon
the effectiveness of that registration statement, the Company shall commence the
Registered Exchange Offer and shall cause the same to remain open for such
period of time, and to be conducted in accordance with such
<PAGE>
 
                                                                               3

procedures as may be required by the applicable provisions of the Exchange Act,
and in any event for not less than 30 days after the date notice of the
Registered Exchange Offer is mailed to the Holders of the Notes.  However, the
Registered Exchange Offer shall be consummated in any event on or prior to the
150th day following the Issue Date.  It shall be the objective of such
Registered Exchange Offer to enable each Holder electing to exchange Notes for
Exchange Notes (assuming that such Holder is not an Affiliate of the Company,
acquires the Exchange Notes in the ordinary course of such Holder's business and
has no arrangements with any person to participate in the distribution of the
Exchange Notes) to trade such Exchange Notes from and after their receipt
without any limitations or restrictions under the Securities Act or the Exchange
Act and without material restrictions under the securities laws of a substantial
proportion of the several states of the United States.

          (b) The Company shall indicate in a "Plan of Distribution" section
contained in the final prospectus constituting a part of the registration
statement relating to the Registered Exchange Offer that any Broker-Dealer who
holds Notes that were acquired for its own account as a result of market-making
activities or other trading activities (other than Notes acquired directly from
the Company), may exchange such Notes for Exchange Notes pursuant to the
Registered Exchange Offer.  However, such Broker-Dealer may be deemed an
"underwriter" within the meaning of the Exchange Act and, therefore, must
deliver a prospectus meeting the requirements of the Exchange Act in connection
with any resales of the Exchange Notes received by it in the Registered Exchange
Offer, which prospectus delivery requirement may be satisfied by the delivery by
such Broker-Dealer of the final prospectus contained in the registration
statement relating to the Registered Exchange Offer.  Such "Plan of
Distribution" section also shall state that the delivery by a Broker-Dealer of
the

final prospectus relating to the Registered Exchange Offer in connection with
resales of Exchange Notes shall not be deemed an admission by such Broker-Dealer
that it is an "underwriter" within the meaning of the Exchange Act, and shall
contain all other information with respect to the resales of the Exchange Notes
by Broker-Dealers that the Commission may require in connection therewith, but
such "Plan of Distribution" shall not name any such Broker-Dealer or disclose
the amount of Exchange Notes held by any such Broker-Dealer except to the extent
required by the Commission as a result of a change in law, rule, regulation or
policy after the date of this Agreement.

          (c) In connection with such Registered Exchange Offer and the offer
and sale of Exchange Notes by Broker-Dealers as contemplated above, the Company
shall take such other and further action, including making appropriate filings
under state securities laws and delivering such number of final prospectuses
relating to the Registered Exchange Offer as any Broker-Dealer proposing to
deliver the same in connection with its resales of Exchange Notes may reasonably
request, as may be necessary to realize the foregoing objectives. The Company
shall cause the registration statement relating to the Registered Exchange Offer
to remain continuously effective for a period of at least 20 Business Days (or
longer if required by applicable law) from the date on which such registration
statement is first declared effective, and shall supplement or amend the
prospectus contained therein to the extent necessary to permit such prospectus
(as supplemented or amended) to be delivered by Broker-Dealers in connection
with their resales of Exchange Notes as aforesaid.

     3.   Shelf Registration. If, (i) because of any change in law or in
          ------------------                                            
currently prevailing interpretations of the Commission's staff, the Company is
not permitted to effect a Registered Exchange Offer or (ii) the Initial
Purchaser, as a Holder, (A) is not eligible to
<PAGE>
 
                                                                               5

participate in the Registered Exchange Offer or (B) participates in the
Registered Exchange Offer and does not receive freely transferable Exchange
Notes in exchange for tendered Notes, in either case as contemplated by Section
2 hereof, the following provisions shall apply:

          (a) The Company shall promptly file with the Commission and thereafter
shall use commercially reasonable efforts to cause to be declared effective, on
or prior to the latter of (i) 120 days after the Issue Date or (ii) 45 days
after the publication of the change of law or interpretation, a registration
statement on an appropriate form under the Securities Act relating to the offer
and sale of the Notes by the Holders thereof from time to time in accordance
with the methods of distribution set forth in such registration statement and
Rule 415 under the Securities Act (the "Shelf Registration Statement").

          (b) The Company agrees to use commercially reasonable efforts to keep
the Shelf Registration Statement continuously effective in order to permit the
prospectus included therein to be usable by the Holders of the Notes for a
period of three years from the Issue Date or such shorter period that will
terminate when all the Notes covered by the Shelf Registration Statement have
been sold; provided that the Company shall be deemed not to have used
           --------                                                  
commercially reasonable efforts to keep the Shelf Registration Statement
effective during the requisite period if it voluntarily takes any action that
would result in Holders of Notes covered thereby not being able to offer and
sell such Notes during that period, unless (i) such action is required by
applicable law, rule, regulation or policy, or (ii) in the judgement of the
Board of Directors of the Company, there is a reasonable likelihood that the
failure to take such voluntary action would adversely affect any existing or
prospective material business situation, transaction, or negotiation or
otherwise materially and adversely
<PAGE>
 
                                                                               6

affect the Company and the taking of such voluntary action does not cause any
such registration statement not to be effective, or delay the filing of any
registration statement, for more than 90 days.  Any such period during which the
Company fails to keep the registration statement effective and usable for offers
and sales of Notes is referred to as a "Suspension Period."  A Suspension Period
shall commence on and include the date that the Company gives notice that the
registration statement is no longer effective or the prospectus included therein
is no longer usable for offers and sales of Notes and shall end on the date when
each Selling Holder either receives the copies of the supplemented or amended
prospectus contemplated by Section 5(b) hereof or is advised in writing by the
Company that use of the prospectus may be resumed. If one or more Suspension
Periods occur, the three-year time period referenced above shall be extended by
the number of days included in each such Suspension Period.

          4.   Restrictions on Public Sale by a Holder of Registrable
               ------------------------------------------------------
Securities. Each Holder whose securities are included in a registration
statement hereunder agrees not to effect any public sale or distribution of the
issue being registered or a similar security of the Company or any securities
convertible into or exchangeable or exercisable for such securities, including a
sale pursuant to Rule 144 under the Securities Act, during the 14 days prior to,
and during the 90-day period beginning on, the effective date of such
registration statement (except as part of such registration), if and to the
extent requested by the Company in the case of a non-underwritten public
offering or if and to the extent requested by the managing Underwriter or
Underwriters in the case of an underwritten public offering.

          (a)  Restrictions on Public Sale by the Company and Others. The 
               -----------------------------------------------------           
Company and its Affiliates agree (i) not to effect any public sale or 
distribution of any securities similar

<PAGE>
 
                                                                               7

to the Registrable Securities (except as part of such registration statement),
during the 14 days prior to, and during the 90-day period beginning on, the
effective date of any such registration statement filed pursuant to Section 2 or
3 hereof and (ii) that any agreement entered into after the date of the
Agreement pursuant to which the Company issues or agrees to issue any privately
placed securities similar to the Registrable Securities shall contain a
provision under which holders of such securities agree not to effect any public
sale or distribution of any such securities during the periods described in (i)
above, in each case including a sale pursuant to Rule 144 under the Securities
Act (except as part of any such registration, if permitted).

     5.   Registration Procedures.
          ----------------------- 

          In connection with any Registered Exchange Offer or Shelf Registration
Statement, the Company shall use commercially reasonable efforts to:

          (a) prepare and file with the Commission a registration statement on
any form for which the Company then qualifies or which counsel for the Company
shall deem appropriate and which form shall be available for the sale of the
Exchange Notes or Registrable Securities, as the case may be, to be registered
thereunder in accordance with the intended method of distribution thereof, and
use commercially reasonable efforts to cause such filed registration statement
to become effective and qualify an indenture relating to the Notes or the
Exchange Notes, as the case may be, substantially in the form contemplated by
the offering memorandum used in connection with the placement of the Notes;
provided (i) that before filing a registration statement or prospectus or any
- --------                                                                     
amendments or supplements thereto, the Company will furnish to one counsel
selected by the Holders who hold, or will hold, as the case may be, a majority
in principal amount of the Registrable Securities to be covered by such
registration statement or exchanged pursuant to the Registered Exchange Offer,
as the 
<PAGE>
 
                                                                               8

case may be, copies of all such documents proposed to be filed,
which documents will be subject to the review of such counsel, and (ii) that
after the filing of the registration statement, the Company will promptly notify
each Holder of any stop order issued or threatened by the Commission and take
all reasonable actions required to prevent the entry of such stop order or to
remove it if entered;

          (b) furnish to each Holder, prior to filing the registration
statement, if requested, copies of such registration statement as proposed to be
filed, and thereafter furnish to such Holder such number of copies of such
registration statement, each amendment and supplement thereto (in each case
including all exhibits thereto), the prospectus included in such registration
statement (including each preliminary prospectus) and such other documents as
such Holder may reasonably request in connection with the Registered Exchange
Offer or in order to facilitate the disposition of the Registrable Securities
owned by such Holder, as the case may be;

          (c) use commercially reasonable efforts to register or qualify such
Exchange Notes or Registrable Securities, as the case may be, under such other
securities or blue sky laws of such jurisdictions in the United States as may be
required in connection with the Registered Exchange Offer or as any Selling
Holder or managing Underwriter reasonably (in light of the intended plan of
distribution) requests and do any and all other acts and things which may be
reasonably necessary or advisable to enable such Selling Holder or managing
Underwriter to consummate the disposition of the Registrable Securities owned by
such Selling Holder in such jurisdictions, provided that the Company will not be
                                           --------                             
required to (i) qualify generally to do business in any jurisdiction where it
would not otherwise be required
<PAGE>
 
                                                                               9

to qualify but for this paragraph (c), (ii) subject itself to taxation in any
such jurisdiction or (iii) consent to general service of process in any such
jurisdiction;

          (d) use commercially reasonable efforts to cause such Exchange Notes
or Registrable Securities, as the case may be, to be registered with or approved
by such other governmental agencies or authorities as may be necessary by virtue
of the business and operations of the Company or its Subsidiaries in connection
with the Registered Exchange Offer or to enable the Selling Holder or Selling
Holders thereof to consummate the disposition of such Registrable Securities;

          (e) notify each Holder of such Registrable Securities that is named as
a Selling Holder in any registration statement filed pursuant to this Agreement,
at any time when a prospectus relating thereto is required to be delivered under
the Securities Act, of the occurrence of an event requiring the preparation of a
supplement or amendment to such prospectus so that, as thereafter delivered to
the purchasers of such Registrable Securities, such prospectus will not contain
an untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances in which they were made, not misleading and
promptly make available to each such Holder any such supplement or amendment;

          (f) enter into customary agreements (including an underwriting
agreement in customary form) and take such other actions as are reasonably
required in order to expedite or facilitate the disposition of such Registrable
Securities;

          (g) make available for inspection, during normal business hours and on
reasonable prior notice, by any Selling Holder of such Registrable Securities,
any Underwriter participating in any disposition pursuant to such registration
statement and any attorney,
<PAGE>
 
                                                                              10

accountant or other professional retained by any such Selling Holder or
Underwriter (collectively, the "Inspectors") all financial and other records,
pertinent corporate documents and properties of the Company and its Subsidiaries
(collectively, the "Records") as shall be reasonably necessary to enable them to
exercise their due diligence responsibility, and cause the Company's and the
Subsidiaries' officers, directors and employees to supply all information
reasonably requested to any such Inspectors in connection with such due
diligence.  The Company may require the Inspector to agree that Records which
the Company determines, in good faith, to be confidential and any Records which
it notifies the Inspectors are confidential shall not be disclosed by the
Inspectors unless (i) the disclosure of such Records is necessary to avoid or
correct a misstatement or omission of a material fact in such registration
statement or (ii) the release of such Records is ordered pursuant to a subpoena
or other order from a court of competent jurisdiction. Each Selling Holder of
such Registrable Securities agrees, and shall cause the Inspectors to agree,
that information obtained by it as a result of such inspections shall be deemed
confidential and shall not be used by it for any purpose whatsoever, other than
the exercise of its due diligence responsibility.  Without limiting the
generality of the preceding sentence, each Selling Holder of such Registrable
Securities agrees, and shall cause the Inspectors to agree, that information
obtained by it as a result of such inspections shall not be used by it as the
basis for any market transactions in the securities of the Company or its
Affiliates unless and until such information is made generally available to the
public. Each Selling Holder of such Registrable Securities further agrees, and
shall cause the Inspectors to agree, that it will, upon learning that disclosure
of such Records is sought in a court of competent jurisdiction, give notice to
the Company and
<PAGE>
 
                                                                              11

allow the Company, at its expense, to undertake appropriate action to prevent
disclosure of the Records deemed confidential;

          (h) in the event such sale is pursuant to an underwritten offering,
use commercially reasonable efforts to obtain a comfort letter or comfort
letters from the Company's independent public accountants in customary form and
covering matters of the type customarily covered by comfort letters as the
managing Underwriter reasonably requests;

          (i) use commercially reasonable efforts to obtain an opinion or
opinions from counsel for the Company, in customary form; and

          (j) otherwise use commercially reasonable efforts to comply with all
applicable rules and regulations of the Commission.

          Notwithstanding any other provision of this Agreement, the Company may
delay the filing of any registration statement for up to 90 days if (i) the
Company would, in the opinion of its counsel, be required to disclose in such
registration statement information not otherwise then required by law to be
publicly disclosed and (ii) in the judgment of the Board of Directors of the
Company, there is a reasonable likelihood that such disclosure, or any other
action to be taken in connection with any registration statement, would
adversely affect any existing or prospective material business situation,
transaction, or negotiation or otherwise materially and adversely affect the
Company.

          The Company may require each Selling Holder of Registrable Securities
to promptly furnish in writing to the Company such information regarding the
distribution of the Registrable Securities as it may from time to time
reasonably request and such other information as may be legally required or
reasonably requested in connection with such registration.
<PAGE>
 
                                                                              12

          Each Selling Holder agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in Section 5(e)
hereof, such Selling Holder will forthwith discontinue disposition of
Registrable Securities pursuant to the registration statement covering such
Registrable Securities until such Selling Holder's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 5(e) hereof, and, if
so directed by the Company, such Selling Holder will deliver to the Company all
copies, other than permanent file copies then in such Selling Holder's
possession, of the most recent prospectus covering such Registrable Securities
at the time of receipt of such notice.

     6.   Registration Expenses.
          --------------------- 

          In connection with any registration statement required to be filed
pursuant to Section 2 or 3 hereunder, the Company shall pay the following
registration expenses (the "Registration Expenses"): (i) all registration and
filing fees, (ii) fees and expenses of compliance with securities or blue sky
laws (including reasonable fees and disbursements of counsel in connection with
blue sky qualifications of the Exchange Notes or Registrable Securities, as the
case may be), (iii) printing expenses, (iv) internal Company expenses
(including, without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties), (v) the fees and expenses
incurred in connection with any listing of the Exchange Notes or Registrable
Securities, as the case may be, (vi) fees and disbursements of counsel for the
Company and customary fees and expenses for independent certified public
accountants retained by the Company (including the expenses of any comfort
letters or costs associated with the delivery by independent certified public
accountants of a comfort letter or comfort letters requested pursuant to Section
5(h) hereof), (vii) the fees and
<PAGE>
 
                                                                              13

expenses of any special experts retained by the Company in connection with such
registration, and (viii) reasonable fees and expenses of one counsel (who shall
be selected by Holders of a majority of the Registrable Securities and who shall
be reasonably acceptable to the Company) for the Holders incurred in connection
with the registration hereunder. The Company shall not have any obligation to
pay any underwriting fees, discounts or commissions attributable to the sale of
Registrable Securities (including, without limitation, fees and expenses of any
qualified independent Underwriter that may be required under the rules of the
National Association of Securities Dealers), or, except as otherwise provided in
clause (viii) above, any out-of-pocket expenses of the Holders (or any agents
who manage their accounts) or fees and disbursements of any counsel for any
Underwriter in any underwritten offering.

          7.   Indemnification; Contribution.
               ----------------------------- 

          (a) Indemnification by the Company. The Company agrees to indemnify
              ------------------------------                                 
and hold harmless each Selling Holder of Registrable Securities, its officers
and directors and each person, if any, who controls such Selling Holder within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act from and against any and all losses, claims, damages, liabilities and
expenses (including reasonable costs of investigation) arising out of or based
upon any untrue statement or alleged untrue statement of a material fact
contained in any registration statement or prospectus relating to the
Registrable Securities or in any amendment or supplement thereto or in any
preliminary prospectus, or arising out of or based upon any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages, liabilities or expenses arise out of, or are based
upon, any such
<PAGE>
 
                                                                              14

untrue statement or omission or allegation thereof based upon information
furnished in writing to the Company by such Selling Holder or on such Selling
Holder's behalf expressly for use therein; and provided that with respect to any
                                               --------                         
untrue statement or omission or alleged untrue statement or omission made in any
preliminary prospectus, the indemnity agreement contained in this paragraph
shall not apply to the extent that any such loss, claim, damage, liability or
expense results from the fact that a current copy of the prospectus was not sent
or given to the person asserting any such loss, claim, damage, liability or
expense at or prior to the written confirmation of the sale of the Registrable
Securities concerned to such person if it is determined that the provision of
such person with a current copy of the prospectus would have cured the defect
giving rise to such loss, claim, damage, liability or expense. The Company also
agrees to indemnify, as applicable, (i) the Broker-Dealers who hold Registrable
Securities acquired for their own accounts pursuant to the Registered Exchange
Offer and their officers, directors and each person who controls such Broker-
Dealers, and (ii) the Underwriters of the Registrable Securities and their
officers, directors and each person who controls such Underwriters, on
substantially the same basis as that of the indemnification of the Selling
Holders provided in this Section 7 if such Broker-Dealers and Underwriters agree
in writing to indemnify and contribute to the Company on substantially the same
basis as the Selling Holders indemnify and contribute to the Company pursuant to
this Section 7.

          (b) Indemnification by Holder of Registrable Securities. Each Selling
              ---------------------------------------------------              
Holder whose Registrable Securities are included in a registration pursuant
hereto, shall be deemed to have agreed to indemnify and hold harmless the
Company, its directors and officers and each person, if any, who controls the
Company within the meaning of either Section 15 of the Securities Act or Section
20 of the Exchange Act from and against any and
<PAGE>
 
                                                                              15

all losses, claims, damages, liabilities and expenses (including reasonable
costs of investigation) arising out of or based upon any untrue statement or
alleged untrue statement of a material fact contained in any registration
statement or prospectus relating to the Registrable Securities or in any
amendment or supplement thereto or in any preliminary prospectus, or arising out
of or based upon any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading; provided that the provisions of this paragraph shall apply only
                --------                                                       
insofar as losses, claims, damages, liabilities or expenses arise out of, or are
based upon, any such untrue statement or omission or allegation thereof based
upon information furnished in writing by such Selling Holder or on such Selling
Holder's behalf expressly for use in any registration statement or prospectus
relating to the Registrable Securities, or any amendment or supplement thereto,
or any preliminary prospectus. In case any action or proceeding shall be brought
against the Company, or its directors or officers, or any such controlling
person, in respect of which indemnity may be sought against such Selling Holder,
such Selling Holder shall have the rights and duties given to the Company, and
the Company or its directors or officers or such controlling person shall have
the rights and duties given to such Selling Holder, by the preceding paragraph.

          (c) Conduct of Indemnification Proceedings. Promptly after receipt of
              --------------------------------------                           
notice of the commencement of any action or proceeding (including any
governmental investigation) brought or asserted against any person entitled to
indemnification under clause (a) or (b) above (an "Indemnified Party") in
respect of which indemnity may be sought from any party who has agreed to
provide such indemnification (an "Indemnifying Party"), if a claim in respect
thereof is to be made against an Indemnifying Party under such clause, the
<PAGE>
 
                                                                              16

Indemnified Party shall notify the Indemnifying Party in writing of the
commencement thereof; provided, that the omission so to notify the Indemnifying
                      --------                                                 
Party shall not relieve it from any liability which it may have under this
Section 7 except to the extent it has been materially prejudiced by such
omission; provided, further, that the omission so to notify the Indemnifying
          --------  -------                                                 
Party shall not relieve it from any liability which it may have to an
Indemnified Party otherwise than under this Section 7.  The Indemnifying Party
shall be entitled to assume the defense thereof, including the employment of
counsel reasonably satisfactory to such Indemnified Party, and shall assume the
payment of all expenses indemnified hereunder. Such Indemnified Party shall have
the right to employ separate counsel in any such action and to participate in
the defense thereof, but the fees and expenses of such separate counsel shall be
at the expense of such Indemnified Party unless (i) the Indemnifying Party has
agreed to pay such fees and expenses or (ii) the named parties to any such
action or proceeding (including any impleaded parties) include both such
Indemnified Party and the Indemnifying Party, and such Indemnified Party shall
have been advised by counsel that there is a conflict of interest on the part of
counsel employed by the Indemnifying Party to represent such Indemnified Party
(in which case, if such Indemnified Party notifies the Indemnifying Party in
writing that it elects to employ separate counsel at the expense of the
Indemnifying Party, the Indemnifying Party shall not have the right to assume
the defense of such action or proceeding on behalf of such Indemnified Party; it
being understood, however, that the Indemnifying Party shall not, in connection
with any one such action or proceeding or separate but substantially similar or
related actions or proceedings in the same jurisdiction arising out of the same
general allegations of circumstances, be liable for the fees and expenses of
more than one separate firm of attorneys (together with appropriate local
counsel)
<PAGE>
 
                                                                              17

at any time for all such Indemnified Parties, which firm shall be designated in
writing by such Indemnified Parties). The Indemnifying Party shall not be liable
for any settlement of any such action or proceeding effected without its written
consent, which shall not be unreasonably withheld, but if settled with its
written consent, or if there be a final judgment for the plaintiff in any such
action or proceeding, the Indemnifying Party shall indemnify and hold harmless
such Indemnified Parties from and against any loss or liability (to the extent
stated above) by reason of such settlement or judgment.

          (d) Contribution. If the indemnification provided for in this Section
              ------------                                                     
7 is due in accordance with the terms hereof but is held to be unavailable to
the Indemnified Parties in respect of any losses, claims, damages, liabilities
or judgments referred to herein (collectively, "losses"), then each such
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such losses (i) as between the Company and the Selling Holders on the one
hand and the Underwriters or Broker-Dealers, as the case may be, on the other,
in such proportion as is appropriate to reflect the relative benefits received
by the Company and the Selling Holders on the one hand and the Underwriters or
Broker-Dealers, as the case may be on the other from the offering of the
Registrable Securities, or if such allocation is not permitted by applicable
law, in such proportion as is appropriate to reflect not only such relative
benefits but also the relative fault of the Company and the Selling Holders on
the one hand and of the Underwriters or Broker-Dealers, as the case may be, on
the other in connection with the statements or omissions which resulted in such
losses, as well as any other relevant equitable considerations and (ii) as
between the Company on the one hand and each Selling Holder on the other, in
such proportion as is appropriate to reflect the relative fault of the Company

of each Selling Holder in connection with such statements or omissions, as well
as any other relevant equitable considerations. The relative benefits received
by the Company and the Selling Holders on the one hand and the Underwriters or
Broker-Dealers, as the case may be, on the other shall be deemed to be in the
same proportion as the total proceeds from the offering (net of underwriting
discounts and commissions but before deducting expenses) received by the Company
and the Selling Holders bear to the total underwriting discounts and commissions
received by the Underwriters or Broker-Dealers, as the case may be, in each case
as set forth in the table on the cover page of the prospectus. The relative
fault of the  Company and the Selling Holders on the one hand and of the
Underwriters or Broker-Dealers, as the case may be, on the other shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company and the Selling
Holders or by the Underwriters or Broker-Dealers, as the case may be. The
relative fault of the Company on the one hand and of each Selling Holder on the
other shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by such party,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

          The Company and the Selling Holders agree that it would not be just
and equitable if contribution pursuant to this Section 7(d) were determined by
pro rata allocation (even if the Underwriters or Broker-Dealers, as the case may
be, were treated as one entity for such purpose) or by any other method of
allocation which does not take account of the equitable considerations referred
to in the immediately preceding paragraph. The amount paid

                                                                              19

or payable by an Indemnified Party as a result of the losses, claims, damages,
liabilities or judgments referred to in the immediately preceding paragraph
shall be deemed to include, subject to the limitations set forth above, any
legal or other expenses reasonably incurred by such Indemnified Party in
connection with investigating or defending any such action or claim and for
which it is entitled to be indemnified hereunder. Notwithstanding the provisions
of this Section 7(d), no Underwriter or Broker-Dealer, as the case may be, shall
be required to contribute any amount in excess of the amount by which the total
price at which the Registrable Securities underwritten by it and distributed to
the public were offered to the public exceeds the amount of any damages which
such Underwriter or Broker-Dealer, as the case may be, has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission, and no Selling Holder shall be required to contribute any
amount in excess of the amount by which the total price at which the Registrable
Securities of such Selling Holder were offered to the public exceeds the amount
of any damages which such Selling Holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.

     8.   Additional Interest Under Certain Circumstances; Remedies.
          --------------------------------------------------------- 

          (a)  In the event (to the extent applicable) that (i) (A) the
Registered Exchange Offer registration statement is not filed on or prior to the
45th day following the Issue Date, (B) the Registered Exchange Offer
registration statement is not declared effective within the earlier of (x) 90
days after the Issue Date or (y) 30 days after the consummation of the initial
<PAGE>
 
                                                                              20

public offering of the Company's Common Stock or (C) the Registered Exchange
Offer is not consummated on or prior to the 150th day following the Issue Date
or (ii) a Shelf Registration Statement with respect to the Notes is not promptly
filed pursuant to Section 3(a) hereof or is not declared effective under the
Securities Act on or prior to the later of (x) the 120th day after the Issue
Date and (y) the 45th day after the publication of the change in law or
interpretation referred to in Section 3, the interest rate borne by the Notes
shall be increased by one-half of one percent per annum following, in the case
of clause (i) (A), such 45-day period, or in the case of clause (i)(B), such 90-
or 30-day period, as the case may be, or in the case of clause (i)(C), such 150-
day period, or in the case of clause (ii), such 120- or 45-day period, as
applicable.  The aggregate amount of such increase from the original interest
rate pursuant to these provisions will in no event exceed one-half of one
percent per annum.  Such increase will cease to be effective on the date of
filing of the Registered Exchange Offer registration statement, effectiveness of
the Registered Exchange Offer registration statement, consummation of the
Registered Exchange Offer or the effectiveness of a Shelf Registration
Statement, as the case may be.

          (b) Any amounts of additional interest due pursuant to the paragraph
above will be payable in cash, on the same original interest payment dates as
the Notes.  The amount of additional interest will be determined by multiplying
the applicable additional interest rate by the principal amount of the affected
Notes of such Holders, multiplied by a fraction, the numerator of which is the
number of days such additional interest rate was applicable during such period
(determined on the basis of the actual number of days elapsed), and the
denominator of which is 360.

     9.   Participation in Underwritten Registrations.

                                                                              21

          No person may participate in any underwritten registration hereunder
unless such person (a) agrees to sell such person's securities on the basis
provided in any underwriting arrangements approved by the persons entitled
hereunder to approve such arrangements and (b) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents reasonably required under the terms of such underwriting
arrangements and this Agreement.

     10.  Rule 144.
          -------- 

          To the extent it is otherwise required to do so, the Company covenants
that it will file any reports required to be filed by it under the Securities
Act and the Exchange Act so as to enable Holders to sell Registrable Securities
without registration under the Securities Act within the limitation of the
exemptions provided by (a) Rule 144 under the Securities Act, as such Rule may
be amended from time to time, or (b) any similar rule or regulation hereafter
adopted by the Commission. Upon the request of any Holder, the Company will
deliver to such Holder a written statement as to whether it has complied with
such requirements.

     11.  Miscellaneous.
          ------------- 

          (a) No Inconsistent Agreements. The Company will not hereafter enter
              --------------------------                                      
into and is not presently a party to any agreement with respect to its
securities which conflicts with the rights granted to the Holders of Registrable
Securities in this Agreement.

          (b) Remedies. Each Holder of Registrable Securities, in addition to
              --------                                                       
being entitled to exercise all rights granted by law, including recovery of
damages, will be entitled to specific performance of its rights under this
Agreement. The Company agrees that monetary damages would not be adequate
compensation for any loss incurred by reason of a

breach by it of the provisions of this Agreement and hereby agrees to waive the
defense in any action for specific performance that a remedy at law would be
adequate. Any breach of this Agreement shall not cause a Default or Event of
Default under the Notes.

          (c) Amendments and Waivers. Except as otherwise provided herein, the
              ----------------------                                          
provisions of this Agreement may not be amended, modified or supplemented, and

affected by such amendment, modification, supplement, waiver or departure.

                              PURCHASE AGREEMENT

                                                               December 19, 1997

SOCIETE GENERALE SECURITIES CORPORATION
1221 Avenue of the Americas
New York, New York  10020

Ladies and Gentlemen:

                  Schein Pharmaceutical, Inc., a Delaware corporation (the
"Company"), proposes to issue and sell $100,000,000 principal amount of its

issued pursuant to an Indenture dated as of December 24, 1997 (the "Indenture")
to be entered into between the Company, the subsidiaries listed on the signature
pages hereto (collectively, the "Guarantors") and The Bank of New York, as
trustee (the "Trustee"). This is to confirm the agreement concerning the
purchase of the Securities from the Company by Societe Generale Securities
Corporation (the "Initial Purchaser"). Payment of principal and interest on the
Securities will be unconditionally guaranteed, jointly and severally, on a
senior unsecured basis (the "Subsidiary Guarantees") by the Guarantors.

                  The Securities will be offered and sold to the Initial
Purchaser without being registered under the Securities Act of 1933, as amended
(the "Securities Act"), in reliance upon an exemption therefrom. The Company has
prepared a preliminary offering memorandum dated December 3, 1997 (the
"Preliminary Offering Memorandum") and will prepare an offering memorandum dated
the date hereof (the "Offering Memorandum") setting forth information concerning
the Company and the Securities. Copies of the Preliminary Offering Memorandum
have been, and copies of the Offering Memorandum will be, delivered by the
Company to the Initial Purchaser pursuant to the terms of this Agreement. Any

use of the Preliminary Offering Memorandum and the Offering Memorandum in
connection with the offering and resale of the Securities by the Initial
Purchaser in accordance with Section 2.

                                                                               2


                  Holders of the Securities (including the Initial Purchaser and
its direct and indirect transferees) will be entitled to the benefits of an
Exchange and Registration Rights Agreement, substantially in the form attached
hereto as Annex A (the "Registration Rights Agreement"), pursuant to which the
Company will agree to file with the Securities and Exchange Commission (the
"Commission") (i) a registration statement under the Securities Act (the
"Exchange Offer Registration Statement") registering an issue of notes of the
Company (the "Exchange Securities") which are identical in all material respects
to the Securities (except that the Exchange Securities will not contain terms
with respect to transfer restrictions) and (ii) under certain circumstances, a
shelf registration statement pursuant to Rule 415 under the Securities Act (the
"Shelf Registration Statement").

                  1. REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF THE COMPANY
AND THE GUARANTORS. The Company and the Guarantors represent and warrant to and
agree, jointly and severally, with the Initial Purchaser that:

                  (a) Accurate Information Relating to the Securities. Each of
         the Preliminary Offering Memorandum and the Offering Memorandum, as of
         its respective date, did not, and on the Closing Date (as defined
         herein) the Offering Memorandum will not, contain any untrue statement
         of a material fact or omit to state a material fact required to be
         stated therein or necessary in order to make the statements therein, in
         the light of the circumstances under which they were made, not
         misleading; provided that neither the Company nor any Guarantor makes
         any representation or warranty as to information contained in or
         omitted from the Preliminary Offering Memorandum or the Offering
         Memorandum in reliance upon and in conformity with written information
         relating to the Initial Purchaser furnished to the Company and the
         Guarantors by or on behalf of the Initial Purchaser specifically for
         use therein (the "Initial Purchaser's Information").

                  (b) Compliance with Securities Act. Each of the Preliminary
         Offering Memorandum and the Offering Memorandum, as of its respective
         date, contains all of the information that, if requested by a
         prospective purchaser of the Securities, would be required to be
         provided to such prospective purchaser pursuant to Rule 144A(d)(4)
         under the Securities Act.

                  (c) Registration Required. Assuming the accuracy of the
         representations and warranties of the Initial Purchaser contained in
         Section and its compliance with the agreements set forth therein, it is
         not necessary, in connection with the issuance and sale of the
         Securities to the Initial Purchaser and the offer, resale and delivery
         of the Securities by the Initial Purchaser in the manner contemplated
         by this Agreement and the Offering Memorandum, to register the
         Securities under the Securities Act or to qualify the Indenture under
         the Trust Indenture Act of 1939, as amended (the "Trust Indenture
         Act").

         each of its subsidiaries that is a "Significant Subsidiary" within the
         meaning of such term as

         "Significant Subsidiary") have been duly incorporated and are validly
         existing as corporations in good standing under the laws of their
         respective jurisdictions of incorporation, are duly qualified to do
         business and are in good standing as foreign corporations in each
         jurisdiction in which their respective ownership or lease of property
         or the conduct of their respective businesses requires such
         qualification, and have all power and authority necessary to own or
         hold their respective properties and to conduct the businesses in which
         they are engaged, except where the failure to so qualify or have such
         power or authority would not have, singularly or in the aggregate, a
         material adverse effect on the condition (financial or otherwise),
         results of operations, business or prospects of the Company and its
         subsidiaries taken as a whole (a "Material Adverse Effect").

                  (e) Corporate Power; Authorization. Each of the Company and
         the Guarantors has full right, power and authority to execute and
         deliver this Agreement, the Registration Rights Agreement, the
         Indenture and the Securities (collectively, the "Transaction
         Documents") and to perform its respective obligations hereunder and
         thereunder; and all corporate action required to be taken for the due

         by the proper officers of the Company and each Guarantor and delivered
         by the Company and each Guarantor, assuming due authorization,
         execution and delivery thereof by the Trustee, will constitute a valid
         and binding agreement of the Company and each Guarantor enforceable
         against the Company and each Guarantor in accordance with its terms,
         subject to the effects of bankruptcy, insolvency, fraudulent

         dealing; the Registration Rights Agreement, when duly executed by the
         proper officers of the Company and delivered by the Company, assuming
         due authorization, execution and delivery thereof by the Initial
         Purchaser, will constitute a valid and binding agreement of the Company
         enforceable against the Company in accordance with its terms, subject
         to the effects of bankruptcy, insolvency, fraudulent conveyance,

         Agreement, will be duly and validly issued and outstanding and will
         constitute valid and binding obligations of the Company entitled to the
         benefits of the Indenture and enforceable against the Company in
         accordance with their terms, subject to the effects of bankruptcy,
         insolvency, fraudulent conveyance, fraudulent transfer, reorganization,

                  (i) No Legal Bar. The execution, delivery and performance of
         each of the Transaction Documents by the Company and each Guarantor and
         the consummation of the transactions contemplated hereby and thereby

         with generally accepted accounting principles consistently applied
         throughout the periods covered thereby and fairly present the financial
         position of the entities purported to be covered thereby at the

         material adjustments to the historical financial information required

         Exchange Act to reflect the transactions described in the Offering
         Memorandum, gives effect to assumptions made on a reasonable basis and
         fairly presents the historical and proposed transactions contemplated

         historical financial and statistical information and data included in
         the Offering Memorandum are, in all material respects, fairly
         presented.

                  (l) No Material Adverse Change. Neither the Company nor any of
         its subsidiaries has sustained, since the date of the latest audited
         financial statements included in the Offering Memorandum, any material
         (determined with respect to the Company and its subsidiaries taken as a
         whole) loss or interference with its business from fire, explosion,
         flood or other calamity, whether or not covered by insurance, or from
         any labor dispute or court or governmental action, order or decree,
         otherwise than as set forth or contemplated in the Offering Memorandum;
         and, since such date, there has not been any change in the capital
         stock or an increase in long-term debt of the Company or any of its
         subsidiaries or any material adverse change, or any development
         involving a prospective material adverse change, in or affecting the
         business, general affairs, management, financial position,
         stockholders' equity or results of operations of the Company and its
         subsidiaries taken as a whole, otherwise than as set forth or

                  (m) No Material Litigation. Other than as disclosed in the
         Offering Memorandum: there is no legal or governmental proceeding
         pending to which the Company or any of its subsidiaries is a party or
         of which any property or assets of the Company or any of its
         subsidiaries is the subject which, singularly or in the aggregate, if
         determined adversely to the Company or any of its subsidiaries, is
         reasonably likely to have a Material Adverse Effect; and to the best of
         the Company's and the Guarantors' knowledge, no such proceedings are
         threatened or contemplated by governmental authorities or threatened by
         others.

                  (n) No Defaults. Neither the Company nor any of its
         subsidiaries (i) is in violation of its charter or by-laws, (ii) is in
         default in any material respect, and no event has occurred which, with
         notice or lapse of time or both, would constitute such a default, in
         the due performance or observance of any term, covenant or condition
         contained in any material indenture, mortgage, deed of trust, loan
         agreement or other agreement or instrument to which it is a party or by
         which it is bound or to which any of its property or assets is subject
         or (iii) is in violation in any respect of any law, ordinance,
         governmental rule, regulation or court decree to which it or its
         property or assets may be subject, except any violations or defaults
         which, singularly or in the aggregate, would not have a Material
         Adverse Effect.

                  (o) Possession of Licenses and Permits. The Company and each
         of its subsidiaries possess all material licenses, certificates,
         authorizations and permits issued by, and have made all declarations
         and filings with, the appropriate state, federal or foreign regulatory
         agencies or bodies which are necessary or desirable for the ownership
         of their respective properties or the conduct of their respective
         businesses as described in the Offering Memorandum, except where any
         failures to possess or make the same, singularly or in the aggregate,
         would not have a Material Adverse Effect, and the Company has not
         received notification of any revocation or modification of any such
         license, authorization or permit and has no reason to believe that any
         such license, certificate, authorization or permit will not be renewed.

                  (p) No Lending Relationships. Except as disclosed in the
         Offering Memorandum, the Company (i) does not have any material lending
         or other relationship with any bank or lending affiliate of the Initial
         Purchaser and (ii) does not intend to use any of the proceeds from the
         sale of the Securities hereunder to repay any outstanding debt owed to
         any affiliate of the Initial Purchaser.

                  (q) Investment Company Act. Neither the Company nor any of its
         subsidiaries is an "investment company" within the meaning of the
         Investment Company Act of 1940, as amended (the "Investment Company
         Act"), and the rules and regulations of the Commission thereunder.

                  (r) No Registration Rights. Except as otherwise disclosed in
         the Offering Memorandum, there are no contracts, agreements or
         understandings between the Company or any Guarantor and any person
         granting such person the right to require the Company or such Guarantor
         to file a registration statement under the Securities
<PAGE>
 
                                                                               7



         Act with respect to any securities of the Company or such Guarantor or
         to require the Company or such Guarantor to include such securities
         with the Securities and Subsidiary Guarantees registered pursuant to
         any Exchange Offer Registration Statement or Shelf Registration
         Statement.

                  (s) No Stabilization. Neither the Company, nor to the
         Company's or the Guarantors' best knowledge, any of its affiliates, has
         taken or may take, directly or indirectly, any action designed to cause
         or result in, or which has constituted or which might reasonably be
         expected to constitute, the stabilization or manipulation of the price
         of the Securities to facilitate the sale or resale of the Securities.

                  (t) Possession of Intellectual Property. The Company and each
         of its subsidiaries own or possess adequate rights to use all material
         patents, patent applications, trademarks, service marks, trade names,
         trademark registrations, service mark registrations, copyrights,
         licenses and know-how (including trade secrets and other unpatented
         and/or unpatentable proprietary or confidential information, systems or
         procedures) necessary for the conduct of their respective businesses,
         except where the absence of which would not reasonably be expected to
         have a Material Adverse Effect. Neither the Company nor any of its
         subsidiaries has reason to believe that the conduct of their respective
         businesses will conflict with, and has not received any notice of any
         claim of conflict with, any such rights of others.

                  (u) Title to Personal Property. The Company and each of its
         subsidiaries have good and marketable title in fee simple to, or have
         valid rights to lease or otherwise use, all items of real or personal
         property which are material to the business of the Company and its
         subsidiaries taken as a whole, in each case free and clear of all
         liens, encumbrances, claims and defects that may result in a Material
         Adverse Effect.

                  (v) Title to Real Property. The Company and each of its
         subsidiaries have good and marketable title in fee simple to all real
         property owned by them, in each case free and clear of all liens,
         encumbrances and defects except such as are described in the Offering
         Memorandum or such as do not materially affect the value of such
         property and do not materially interfere with the use made and proposed
         to be made of such property by the Company and its subsidiaries; and
         all real property and buildings held under lease by the Company and its
         subsidiaries are held by them under valid, subsisting and enforceable
         leases, with such exceptions as are not material and do not interfere
         with the use made and proposed to be made of such property and
         buildings by the Company and its subsidiaries.

                  (w) No Labor Dispute. No labor disturbance by the employees of
         the Company or any of its subsidiaries exists or, to the best of the
         Company's knowledge, is imminent which might be expected to have a
         Material Adverse Effect.

                  (x) Employee Benefit Plans. No "prohibited transaction" (as
         defined in Section 406 of the Employee Retirement Income Security Act
         of 1974, as amended, including the regulations and published
         interpretations thereunder ("ERISA"), or 
<PAGE>
 
                                                                               8

         Section 4975 of the Internal Revenue Code of 1986, as amended from time
         to time (the "Code")) or "accumulated funding deficiency" (as defined
         in Section 302 of ERISA) or any of the events set forth in Section
         4043(b) of ERISA (other than events with respect to which the 30-day
         notice requirement under Section 4043 of ERISA has been waived) has
         occurred with respect to any employee benefit plan which could have a
         Material Adverse Effect; each employee benefit plan is in compliance in
         all material respects with applicable law, including ERISA and the
         Code; the Company has not incurred and does not expect to incur
         liability under Title IV of ERISA with respect to the termination of,
         or withdrawal from, any "pension plan"; and each "pension plan" (as
         defined in ERISA) for which the Company would have any liability that
         is intended to be qualified under Section 401(a) of the Code is so
         qualified in all material respects, and nothing has occurred, whether
         by action or by failure to act, which could cause the loss of such
         qualification.

                  (y) No Material Environmental Liabilities. There has been no
         storage, generation, transportation, handling, treatment, disposal,
         discharge, emission, or other release of any kind of toxic or other
         wastes or other hazardous substances by, due to, or caused by the
         Company or any of its subsidiaries (or, to the best of the Company's
         knowledge, any other entity for whose acts or omissions the Company or
         any of its subsidiaries is or may be liable) upon any of the property
         now or previously owned or leased by the Company or any of its
         subsidiaries, or upon any other property, in violation of any statute
         or any ordinance, rule, regulation, order, judgment, decree or permit
         or which would, under any statute or any ordinance, rule (including
         rule of common law), regulation, order, judgment, decree or permit,
         give rise to any liability, except for any violation or liability which
         would not have, singularly or in the aggregate with all such violations
         and liabilities, a Material Adverse Effect; there has been no disposal,
         discharge, emission or other release of any kind onto such property or
         into the environment surrounding such property of any toxic or other
         wastes or other hazardous substances with respect to which the Company
         or any of its subsidiaries have knowledge, except for any such
         disposal, discharge, emission, or other release of any kind which would
         not have, singularly or in the aggregate with all such discharges and
         other releases, a Material Adverse Effect.

                  (z) Taxes. The Company and its subsidiaries each (i) have
         filed all necessary federal, state and foreign income and franchise tax
         returns, (ii) have paid all federal, state, local and foreign taxes due
         and payable for which it is liable, including, but not limited to,
         withholding taxes and amounts payable under the Code, except to the
         extent any taxes in question are being contested in good faith through
         appropriate proceedings and as to which reserves have been established,
         and has furnished all information returns it is required to furnish
         pursuant to the Code, (iii) have established adequate reserves for all
         such taxes which are not yet due and payable and (iv) do not have any
         tax deficiency or claims outstanding or assessed or, to the best of the
         Company's knowledge, proposed against it which could reasonably be
         expected to have a Material Adverse Effect.

                                                                               9

                  (aa) Insurance Policies. The Company and its subsidiaries each
         maintain insurance policies and surety bonds, including, but not
         limited to, general liability and property insurance, which insures the
         Company and each of its subsidiaries and their respective employees
         against losses and risks generally insured against by comparable
         companies in comparable businesses. Neither the Company nor any of its
         subsidiaries (i) has failed to give notice or to present any insurance
         claim with respect to any material matter, including, but not limited
         to, the Company's or the subsidiaries' respective business, property or
         employees under any insurance policy or surety bond in a due and timely
         manner, (ii) has any material disputes or claims against any
         underwriter of such insurance policies or surety bonds or has failed to
         pay any premiums due and payable thereunder or (iii) has failed to
         comply with any material conditions contained in such insurance
         policies and surety bonds. To the best of the Company's knowledge,
         there are no facts or circumstances under any such insurance policy or
         surety bond which would relieve any insurer of its obligation to
         satisfy in full any valid claim of the Company or any of its
         subsidiaries.

                  (bb) Accounting Controls. The Company and each of its
         subsidiaries maintain a system of internal accounting controls
         sufficient to provide reasonable assurance that (i) transactions are
         executed in accordance with management's general or specific
         authorizations; (ii) transactions are recorded as necessary to permit
         preparation of financial statements in conformity with generally
         accepted accounting principles and to maintain asset accountability;
         (iii) access to assets is permitted only in accordance with
         management's general or specific authorization; and (iv) the recorded
         accountability for assets is compared with the existing assets at
         reasonable intervals and appropriate action is taken with respect to
         any differences.

                  (cc) Minute Books. The minute books of the Company and each of
         its Significant Subsidiaries have been made available to the Initial
         Purchaser and counsel for the Initial Purchaser, and such books (i)
         contain a complete summary of all meetings and actions of the directors
         and stockholders of the Company and each of its subsidiaries since the
         time of its respective incorporation through the date of the latest
         meeting and action (except for certain meetings identified on and
         certified by the Secretary of the Company on a certificate of such
         Secretary which has previously been provided to the Initial Purchaser),
         and (ii) accurately in all material respects reflect all transactions
         referred to in such minutes.

                  (dd) Transactions with Management and Others. No relationship,
         direct or indirect, exists between or among the Company or the
         Guarantors on the one hand, and the directors, officers, stockholders,
         customers or suppliers of the Company or the Guarantors on the other
         hand, which is required to be described in the Offering Memorandum and
         which is not so described.

                  (ee) No Outstanding Subscriptions. Except as described in the
         Offering Memorandum, there are no outstanding subscriptions, rights,
         warrants, calls or options to acquire, or instruments convertible into
         or exchangeable for, or agreements or 
<PAGE>
 
                                                                              10


         understandings with respect to the sale or issuance of, any shares of
         capital stock of or other equity or other ownership interest in the
         Company or any of its subsidiaries.

                  (ff) Solvency. On and immediately after the Closing Date, the
         Company (after giving effect to the issuance of the Securities and to
         the other transactions related thereto as described in the Offering
         Memorandum) will be Solvent. As used in this paragraph, the term
         "Solvent" means, with respect to a particular date, that on such date
         (i) the present fair market value (or present fair saleable value) of
         the assets of the Company on a consolidated basis is not less than the
         total amount required to pay the probable liabilities of the Company on
         a consolidated basis on its total existing debts and liabilities
         (including contingent liabilities) as they become absolute and matured,
         (ii) the Company is able to realize upon its assets and pay its debts
         and other liabilities, contingent obligations and commitments as they
         mature and become due in the normal course of business, (iii) assuming
         the sale of the Securities as contemplated by this Agreement and the
         Offering Memorandum, the Company is not incurring debts or liabilities
         beyond its ability to pay as such debts and liabilities mature and (iv)
         the Company is not engaged in any business or transaction, and is not
         about to engage in any business or transaction, for which its property
         would constitute unreasonably small capital after giving due
         consideration to the capital needs of the Company, taking into account
         the projected capital requirements and the capital available to the
         Company. In computing the amount of such contingent liabilities at any
         time, it is intended that such liabilities will be computed at the
         amount that, in the light of all the facts and circumstances existing
         at such time, represents the amount that can reasonably be expected to
         become an actual or matured liability.

                  (gg) Material Agreements or Instruments. Except as set forth
         on Annex 2 to the opinion to be delivered by Proskauer Rose LLP,
         pursuant to Section 5(d) hereof, there are no other material documents
         or instruments to which the Company or any of its Significant
         Subsidiaries is bound or to which the properties or assets of the
         Company or its Significant Subsidiaries is subject.

         System (the "Federal Reserve Board"), for the purpose of reducing or
         retiring any indebtedness which was originally incurred to purchase or
         carry any margin security or for any other purpose which might cause
         any of the Securities to be considered a "purpose credit" within the
         meanings of Regulation G, T, U or X of the Federal Reserve Board.

                  (ii) No Brokerage Fees. Neither the Company nor any of its
         subsidiaries is a party to any contract, agreement or understanding
         with any person that would give rise to a valid claim by such person

         Purchaser for a brokerage commission, finder's fee or like payment in
         connection with the offering and sale of the Securities.

         for the Initial Purchaser or counsel for the Company, to amend or
         supplement the Offering Memorandum in order that the Offering
         Memorandum will not include an untrue statement of a material fact or
         omit to state a material fact necessary in order to make the statements
         therein, in the light of the circumstances existing at the time it is

         Initial Purchaser may reasonably require, and the Company shall have

         a certificate, dated the Closing Date, of its Chairman of the Board,
         its President, any executive vice president, senior vice president or

         examined the Offering Memorandum (ii) in his opinion, the Offering
         Memorandum, as of its date, did not include any untrue statement of a
         material fact and did not omit to state a material fact required to be
         stated therein or necessary to make the statements therein not
         misleading, and since the date of the Offering Memorandum, no event has
         occurred which should have been set forth in a supplement or amendment
         to the Offering Memorandum and (iii) to the best of his knowledge after
         reasonable investigation, as of the Closing Date, the Company and each
         Guarantor have complied with all agreements and satisfied all
         conditions on their part to be performed or satisfied hereunder at or
         prior to the Closing Date.

                  (j) The Initial Purchaser shall have received a counterpart of
         the Registration Rights Agreement which shall have been executed and
         delivered by a duly authorized officer of the Company.

                  (k) The Indenture shall have been duly executed and delivered

                  (m) If any event shall have occurred that requires the Company
         under Section 4(d) to prepare an amendment or supplement to the
         Offering Memorandum, such amendment or supplement shall have been
         prepared, the Initial Purchaser shall

                                                                              19

         have been given a reasonable opportunity to comment thereon, and copies
         thereof shall have been delivered to the Initial Purchaser reasonably
         in advance of the Closing Date.

                  (n) There shall not have occurred any invalidation of Rule
         144A under the Securities Act by any court or any withdrawal or
         proposed withdrawal of any rule or regulation under the Securities Act
         or the Exchange Act by the Commission or any amendment or proposed
         amendment thereof by the Commission which in the judgment of the
         Initial Purchaser would materially impair the ability of the Initial
         Purchaser to purchase, hold or effect resales of the Securities as
         contemplated hereby.

                  (o) No action shall have been taken and no statute, rule,
         regulation or order shall have been enacted, adopted or issued by any
         governmental agency or body which would, as of the Closing Date,
         prevent the issuance or sale of the Securities; and no injunction,
         restraining order or order of any other nature by any federal or state
         court of competent jurisdiction shall have been issued as of the
         Closing Date which would prevent the issuance or sale of the
         Securities.

                  All opinions, letters, evidence and certificates mentioned
above or elsewhere in this Agreement shall be deemed to be in compliance with
the provisions hereof only if they are in form and substance reasonably
satisfactory to counsel for the Initial Purchaser.

                  6. REPRESENTATIONS OF THE INITIAL PURCHASER. The Initial
Purchaser represents to and agree, jointly and severally, with the Company and
each of the Guarantors:

                  (a) Corporate Power; Authorization. The Initial Purchaser has
         full right, power and authority to execute and deliver this Agreement
         and the Registration Rights Agreement and to perform its respective
         obligations hereunder and thereunder; and all corporate action required
         to be taken for the due and proper authorization, execution and
         delivery of each of this Agreement and the Registration Rights
         Agreement and the consummation of the transactions contemplated by this
         Agreement have been duly and validly taken.

                  (b) Enforceable Obligations. The Registration Rights
         Agreement, when duly executed by the proper officers of the Initial
         Purchaser and delivered by the Initial Purchaser, assuming due
         authorization, execution and delivery thereof by the Company, will
         constitute a valid and binding agreement of the Initial Purchaser
         enforceable against the Initial Purchaser in accordance with its terms,
         subject to the effects of bankruptcy, insolvency, fraudulent
         conveyance, fraudulent transfer, reorganization, moratorium and other
         similar laws relating to or affecting creditors' rights generally,
         general equitable principles (whether considered in a proceeding in
         equity or at law) and an implied covenant of good faith and fair
         dealing.

                  7. REIMBURSEMENT OF INITIAL PURCHASER'S EXPENSES. If (a) the
Company shall fail to tender the Securities for delivery to the Initial
Purchaser for any reason permitted under this Agreement, (b) the Initial
Purchaser shall decline to purchase the Securities for any reason permitted
under this Agreement or (c) the Initial Purchaser shall purchase the Securities
<PAGE>
 
                                                                              20


pursuant to this Agreement, the Company shall reimburse the Initial Purchaser
for the fees and expenses of their counsel and for such other out-of-pocket
expenses as shall have been reasonably incurred by them in connection with this
Agreement and the proposed purchase and resale of the Securities, and upon
demand the Company shall pay the full amount thereof to the Initial Purchaser.

                  8. INDEMNIFICATION OF THE INITIAL PURCHASER AND THE COMPANY.
(a) Indemnification of the Initial Purchaser. The Company and each Guarantor,
jointly and severally, shall indemnify and hold harmless the Initial Purchaser
and each person, if any, who controls the Initial Purchaser within the meaning
of the Securities Act (collectively referred to for the purposes of this Section
8 as the Initial Purchaser) against any loss, claim, damage or liability, joint
or several, or any action in respect thereof, to which the Initial Purchaser may
become subject, under the Securities Act or otherwise, insofar as such loss,
claim, damage, liability or action arises out of or is based upon (i) any untrue
statement or alleged untrue statement of a material fact contained in the
Preliminary Offering Memorandum or the Offering Memorandum or in any amendment
or supplement thereto or (ii) the omission or alleged omission to state in the
Preliminary Offering Memorandum or the Offering Memorandum or in any amendment
or supplement thereto a material fact required to be stated therein or necessary
to make the statements therein not misleading, and shall reimburse the Initial
Purchaser for any legal or other expenses reasonably incurred by the Initial
Purchaser in connection with investigating or preparing to defend or defending
against or appearing as a third party witness in connection with any such loss,
claim, damage, liability or action as such expenses are incurred; provided,
however, that the foregoing indemnification agreement with respect to the
Preliminary Offering Memorandum shall not inure to the benefit of the Initial
Purchaser if (i) a copy of the Offering Memorandum (as then amended or
supplemented) was required by law to be delivered to the person asserting any
such loss, claim, damage or liability at or prior to the written confirmation of
the sale of Securities to such person, (ii) a copy of the Offering Memorandum
(as then amended or supplemented) was not sent or given to such person by or on
behalf of the Initial Purchaser and (iii) the Offering Memorandum (as so amended
or supplemented) would have cured the defect giving rise to such loss, claim,
damage or liability; and further provided, however, that the Company and the
Guarantors shall not be liable in any such case to the extent that any such
loss, claim, damage, liability or action arises out of or is based upon (i) an
untrue statement or alleged untrue statement in or omission or alleged omission
from the Preliminary Offering Memorandum or the Offering Memorandum or any such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company and the Guarantors through the Initial
Purchaser specifically for use therein, which information the parties hereto
agree is limited to the Initial Purchaser's Information.

                  (b) Indemnification of Company, Directors and Officers. The
Initial Purchaser shall indemnify and hold harmless the Company and each
Guarantor, their respective directors and officers, and each person, if any, who
controls the Company or Guarantor within the meaning of the Securities Act
(collectively referred to for the purposes of this Section 8 as the Company),
against any loss, claim, damage or liability, joint or several, or any action in
respect thereof, to which the Company or any Guarantor may become subject, under
the Securities Act or otherwise, insofar as such loss, claim, damage, liability
or action arises out 
<PAGE>
 
                                                                              21

of or is based upon (i) any untrue statement or alleged untrue statement of a
material fact contained in the Preliminary Offering Memorandum or the Offering
Memorandum or in any amendment or supplement thereto or (ii) the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, but in each case
only to the extent that the untrue statement or alleged untrue statement or
omission or alleged omission was made in reliance upon and in conformity with
written information furnished to the Company through the Initial Purchaser by or
on behalf of the Initial Purchaser specifically for use therein, and shall
reimburse the Company or such Guarantor for any legal or other expenses
reasonably incurred by the Company or such Guarantor in connection with
investigating or preparing to defend or defending against or appearing as third
party witness in connection with any such loss, claim, damage, liability or
action as such expenses are incurred; provided that the parties hereto hereby
agree that such written information provided by the Initial Purchaser consists
solely of the Initial Purchaser's Information.

                  (c) Actions; Notification. Promptly after receipt by an
indemnified party under this Section 8 of notice of any claim or the
commencement of any action, the indemnified party shall, if a claim in respect
thereof is to be made against the indemnifying party under this Section 8,
notify the indemnifying party in writing of the claim or the commencement of
that action; provided, however, that the failure to notify the indemnifying
party shall not relieve it from any liability which it may have under this
Section 8 except to the extent it has been materially prejudiced by such
failure; and, provided, further, that the failure to notify the indemnifying
party shall not relieve it from any liability which it may have to an
indemnified party otherwise than under this Section 8. If any such claim or
action shall be brought against an indemnified party, and it shall notify the
indemnifying party thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it wishes, jointly with any other
similarly notified indemnifying party, to assume the defense thereof with
counsel reasonably satisfactory to the indemnified party. After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 8 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
any indemnified party shall have the right to employ separate counsel in any
such action and to participate in the defense thereof, but the fees and expenses
of such counsel shall be at the expense of such indemnified party unless (i) the
employment thereof has been specifically authorized by the indemnifying party in
writing, (ii) such indemnified party shall have been advised in writing (a copy
of which shall be provided to the indemnifying party) by such counsel that there
may be one or more legal defenses available to it which are different from or
additional to those available to the indemnifying party and in the reasonable
judgment of such counsel it is advisable for such indemnified party to employ
separate counsel or (ii) the indemnifying party has failed to assume the defense
of such action and employ counsel reasonably satisfactory to the indemnified
party, in which case, if such indemnified party notifies the indemnifying party
in writing that it elects to employ separate counsel at the expense of the
indemnifying party, the indemnifying party shall not have the right to assume
the defense of such action on behalf of such indemnified party, it being
understood, however, that the indemnifying party shall not, in connection with
any one such action or
<PAGE>
 
                                                                              22

separate but substantially similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys at any
time for all such indemnified parties, which firm shall be designated in writing
by the Initial Purchaser (without giving effect to the first parenthetical
contained in Section 8(a)), if the indemnified parties under this Section 8
consist of the Initial Purchaser or any of its officers, employees or
controlling persons, or by the Company (without giving effect to the
parenthetical contained in Section 8(b)), if the indemnified parties under this
Section 8 consist of the Company or any of the Company's directors, officers,
employees or controlling persons. Each indemnified party, as a condition of the
indemnity agreements contained in Sections 8(a) and 8(b), shall use all
reasonable efforts to cooperate with the indemnifying party in the defense of
any such action or claim. Subject to the provisions of Section 8(d) below, no
indemnifying party shall be liable for any settlement of any such action
effected without its written consent (which consent shall not be unreasonably
withheld), but if settled with its written consent or if there be a final
judgment for the plaintiff in any such action, the indemnifying party agrees to
indemnify and hold harmless any indemnified party from and against any loss or
liability by reason of such settlement or judgment.

                  (d) Settlement without Consent if Failure to Reimburse. If at
any time an indemnified party shall have requested that an indemnifying party
reimburse the indemnified party for fees and expenses of counsel, such
indemnifying party agrees that it shall be liable for any settlement of the
nature contemplated by this Section 8 effected without its written consent if
(i) such settlement is entered into more than 45 days after receipt by such
indemnifying party of the request for reimbursement, (ii) such indemnifying
party shall have received notice of the terms of such settlement at least 30
days prior to such settlement being entered into and (iii) such indemnifying
party shall not have reimbursed such indemnified party in accordance with such
request prior to the date of such settlement.

                  (e) Contribution. If the indemnification provided for in this
Section 8 is unavailable or insufficient to hold harmless an indemnified party
under Section 8(a) or (b), then each indemnifying party shall, in lieu of
indemnifying such indemnified party, contribute to the amount paid or payable by
such indemnified party as a result of such loss, claim, damage or liability, or
action in respect thereof, (i) in such proportion as shall be appropriate to
reflect the relative benefits received by the Company and the Guarantors on the
one hand and the Initial Purchaser on the other from the offering of the
Securities or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Company and the Guarantors on the one hand and the Initial
Purchaser on the other with respect to the statements or omissions which
resulted in such loss, claim, damage or liability, or action in respect thereof,
as well as any other relevant equitable considerations. The relative benefits
received by the Company and the Guarantors on the one hand and the Initial
Purchaser on the other with respect to such offering shall be deemed to be in
the same proportion as the total net proceeds from the offering of the
Securities purchased under this Agreement (before deducting expenses) received
by the Company and the Guarantors bear to the total underwriting discounts and
commissions received by the Initial Purchaser with respect to the Securities
purchased under this Agreement, in each case
<PAGE>
 
                                                                              23

as set forth in the Offering Memorandum. The relative fault shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company and the Guarantors
on the one hand or the Initial Purchaser on the other, the intent of the parties
and their relative knowledge, access to information and opportunity to correct
or prevent such untrue statement or omission; provided that the parties hereto
agree that the written information furnished to the Company by the Initial
Purchaser for use in the Preliminary Offering Memorandum, or the Offering
Memorandum consists solely of the Initial Purchaser's Information. The Company
and the Initial Purchaser agree that it would not be just and equitable if
contributions pursuant to this Section 8(e) were to be determined by pro rata
allocation or by any other method of allocation which does not take into account
the equitable considerations referred to herein. The amount paid or payable by
an indemnified party as a result of the loss, claim, damage or liability, or
action in respect thereof, referred to above in this Section 8(e) shall be
deemed to include, for purposes of this Section 8(e), any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 8(e), the Initial Purchaser shall not be required to
contribute any amount in excess of the amount by which the total price at which
the Securities underwritten by it and distributed to the public were offered to
the public less the amount of any damages which the Initial Purchaser has
otherwise paid or become liable to pay by reason of any untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

                  The obligations of the Company, the Guarantors and the Initial
Purchaser in this Section 8 are in addition to any other liability which the
Company, the Guarantors or the Initial Purchaser, as the case may be, may
otherwise have.

                  9. PERSONS ENTITLED TO BENEFIT OF AGREEMENT. This Agreement
shall inure to the benefit of and be binding upon the Initial Purchaser, the
Company, the Guarantors and their respective successors. Nothing expressed or
mentioned in this Agreement is intended or shall be construed to give any
person, firm or corporation, other than the Initial Purchaser, the Company, the
Guarantors and their respective successors and the controlling persons and
officers and directors referred to in Section 8 and their heirs and legal
representatives, any legal or equitable right, remedy or claim under or in
respect of this Agreement or any provision contained herein.

                  10. EXPENSES. In addition to the Company's obligations under
Section 7, the Company and the Guarantors agree with the Initial Purchaser to
pay (a) the costs incident to the authorization, issuance, sale, preparation and
delivery of the Securities and any taxes payable in that connection; (b) the
costs incident to the preparation, printing and distribution of the Preliminary
Offering Memorandum, the Offering Memorandum and any amendments and exhibits
thereto and the costs of printing, reproducing and distributing the applicable
Transaction Documents by mail, telex or other means of communications; (c) all
expenses and listing fees incurred in connection with the application for
quotation of the Securities on the PORTAL Market and the approval of the
Securities for book-entry transfer by The

Depository Trust Company; (d) any applicable listing or other fees; (e) the fees
and expenses of qualifying the Securities under the securities laws of the
several jurisdictions as provided in Section 4(g) and of preparing, printing and
distributing Blue Sky Memoranda and Legal Investment Surveys (including related
fees and expenses of counsel to the Initial Purchaser); (f) any fees charged by
securities rating services for rating the Securities; (g) all fees and expenses
of the Trustee and any agent thereof; and (h) all other costs and expenses
incident to the performance of the obligations of the Company under this
Agreement (including, without limitation, the fees and expenses of counsel to
the Company and the fees and expenses of BDO Seidman LLP).

                  11. SURVIVAL. The respective indemnities, rights of
contribution, representations, warranties and agreements of the Company, the
Guarantors and the Initial Purchaser contained in this Agreement or made by or
on behalf on them, respectively, pursuant to this Agreement, shall survive the
delivery of and payment for the Securities and shall remain in full force and
effect, regardless of any termination or cancellation of this Agreement or any
investigation made by or on behalf of any of them or any person controlling any
of them.

                  12. NOTICES, ETC. All statements, requests, notices and

OFFERING MEMORANDUM                                                CONFIDENTIAL

                         [LOGO] SCHEIN PHARMACEUTICAL
 
                      SENIOR FLOATING RATE NOTES DUE 2004
 

                               -----------------
 
  Schein Pharmaceutical, Inc. ("Schein" or the "Company") is offering (the
"Offering") $100,000,000 of Senior Floating Rate Notes due 2004 (the "Notes").
Interest on the Notes will be payable quarterly on January 15, April 15, July
15 and October 15 of each year, commencing on January 15, 1998, at a rate per
annum equal to the Applicable LIBOR Rate (as defined herein). Interest on the
Notes will be reset quarterly. The Notes will mature on December 15, 2004
unless previously redeemed. The Notes will be redeemable, in whole or in part,
at the option of the Company, at any time, at the redemption prices set forth
herein, plus accrued and unpaid interest thereon, to the date of redemption.
Upon the occurrence of a Change of Control (as defined herein), each holder of
Notes may require the Company to repurchase such holder's Notes, in whole or
in part, at a repurchase price of 101% of the principal amount, plus accrued
and unpaid interest thereon, to the date of repurchase. The Company currently
expects to repurchase or redeem a portion of the Notes offered hereby. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources" and "Description of Notes."
 
  The indebtedness evidenced by the Notes will be senior unsecured obligations
of the Company, will rank pari passu in right of payment with all existing and
future senior indebtedness of the Company and will rank senior in right of
payment to all existing and future indebtedness of the Company that is, by its
terms, expressly subordinated to the Notes. Holders of secured indebtedness of
the Company, including the lenders under the Senior Credit Agreement (as
defined herein), will have claims with respect to the assets constituting
collateral for such indebtedness that are prior to the claims of holders of
the Notes. In the event of a default on the Notes, or a bankruptcy,
liquidation or reorganization of the Company, such assets will be available to
satisfy obligations with respect to the indebtedness secured thereby before
any payment therefrom could be made on the Notes. To the extent that the value
of such collateral is not sufficient to satisfy the indebtedness secured
thereby, amounts remaining outstanding on such indebtedness would be entitled
to share with the Notes and their claims with respect to any other assets of
the Company. As of September 27, 1997, as adjusted for the Offering, the
Company and its Restricted Subsidiaries (as defined herein) would have had
secured indebtedness of approximately $160.6 million outstanding. The
obligations of the Company and the Guarantors (as defined herein) under the
Senior Credit Agreement are secured by substantially all of the assets of the
Company and the Guarantors. As of September 27, 1997, as adjusted for the
Offering, the Company would have had approximately $69.8 million of undrawn
availability under the Senior Credit Agreement. The Indenture relating to the
Notes (the "Indenture") will permit the Company and the Restricted
Subsidiaries to incur additional Indebtedness (as defined herein), including
Secured Indebtedness (as defined herein), subject to certain limitations. See
"Description of Notes."
 
  All of the Company's existing and future Restricted Subsidiaries will
unconditionally guarantee on a senior unsecured basis the performance and
punctual payment when due, whether at maturity, by acceleration or otherwise,
of all obligations of the Company under the Indenture and the Notes (the
"Subsidiary Guarantees"). Each of the Guarantors has guaranteed the Company's
indebtedness under the Senior Credit Agreement on a senior secured basis. The
Subsidiary Guarantees will rank pari passu in right of payment with all
existing and future unsecured senior indebtedness of the Guarantors and senior
in right of payment to all future subordinated indebtedness of the Guarantors.
The Subsidiary Guarantee of each Guarantor will be effectively subordinated to
the prior payment in full of all secured indebtedness of such Guarantors,
including secured indebtedness under the Senior Credit Agreement. See
"Description of Notes--Guarantees."
 
  The Notes have been designated eligible for trading in the Private
Offerings, Resales and Trading through Automated Linkages (PORTAL) market. The
Company and the Restricted Subsidiaries have agreed, for the benefit of all
holders of the Notes, that, after the sale of the Notes, they will file a
registration statement relating to an exchange offer for the Notes under the
Securities Act (as defined herein) for another series of notes with
substantially the same terms as the Notes offered hereby. See "Exchange Offer
and Registration Rights Agreement."

  SEE "RISK FACTORS" BEGINNING ON PAGE 9 FOR A DISCUSSION OF CERTAIN FACTORS
THAT SHOULD BE CONSIDERED IN CONNECTION WITH AN INVESTMENT IN THE NOTES.
                               -----------------

                              December 24, 1997.

products under development, including 24 ANDAs filed with FDA. The Company
supplements its internal product development, manufacturing and marketing
capabilities through strategic collaborations. Schein generated net revenues of
$478.0 million and EBITDA (as defined) of $55.8 million during the 12 months
ended September 1997.
 
  The Company believes it manufactures and markets the broadest product line of
any U.S. pharmaceutical company in terms of number and types of products. The
Company manufactures and markets approximately 160 chemical entities formulated
in approximately 350 different dosages under approximately 200 ANDAs approved
by FDA. Schein is currently the sole manufacturing source for 47 generic
pharmaceutical products, of which 45 are sterile dosage products. The Company's
solid dosage products include both immediate-release and extended-release
capsules and tablets; sterile dosage products include solutions, suspensions,
powders and lyophilized (freeze-dried) products primarily for administration as
injections, ophthalmics and otics. The manufacture of sterile dosage products
is significantly more complex than the manufacture of solid dosage products,
which limits competition in this product area. The Company currently
manufactures approximately four billion solid dosage tablets and capsules and
75 million sterile dosage vials and ampules annually. Solid dosage generic
products and sterile dosage generic products each accounted for approximately
40% of the Company's net revenues in the 12 months ended September 1997.
 
  Since introducing INFeD in 1992, the Company has been developing a portfolio
of branded products, primarily in select therapeutic markets, such as iron
management for the nephrology, oncology and hematology markets. INFeD is used
in the treatment of certain types of anemia, particularly in dialysis patients,
and accounted for approximately 20% of the Company's net revenues in the nine
months ended September 1997. The Company markets INFeD through a 20-person
dedicated sales and marketing force, as well as through co-marketing
collaborations with Bayer Corporation in the nephrology market and MGI Pharma,
Inc. ("MGI") in the oncology market.
 
  The Company believes its 120-person direct sales and marketing force is the
largest in the U.S. generic pharmaceutical industry. Through its customized
marketing programs, the Company markets its products to approximately 60,000
customers representing all major customer channels, including pharmaceutical
wholesalers, chain and independent drug retailers, hospitals, managed care
organizations, other group purchasing organizations and physicians.

  The Company's commitment to product development has resulted in 23 ANDA
approvals during the past three years and its current pipeline of 24 pending
ANDAs and over 60 additional products under development. During the past three
fiscal years, the Company, directly and through its strategic collaborations,
has expended approximately $74.0 million on product pipeline development
activities, which the Company believes is among the highest product development
expenditure levels for any independent generic drug company. The Company
pursues product development through its 140-person product development staff
and various collaborations and licensing arrangements with other pharmaceutical
and drug delivery technology companies. The Company's product development
efforts focus on: (i) major branded drugs coming off patent; (ii) drugs for
which patent protection has lapsed and for which there are few or no generic
producers; (iii) drugs whose patents may be susceptible to challenge; (iv)
proprietary and branded products focused in select therapeutic areas; and (v)
generic products that require specialized development, formulation, drug
delivery or manufacturing technology.
 
  The Company supplements its internal product development, manufacturing and
marketing capabilities from external sources. During 1994, Schein entered into
a strategic alliance with Bayer Corporation, through which Bayer Corporation
became a 28.3% stockholder of Schein, and Bayer Corporation currently
participates with Schein in several collaborations. In 1995, the Company
acquired Marsam Pharmaceuticals Inc. ("Marsam"), expanding the Company's
ability to develop and manufacture sterile penicillins and oral and sterile
cephalosporins. In addition, the Company has entered into strategic
collaborations involving product development arrangements with companies such
as Elan Corporation plc ("Elan") and Ethical Holdings plc ("Ethical"); raw
material supply arrangements with companies such as Johnson Matthey plc
("Johnson Matthey") and Abbott Laboratories ("Abbott"); and sales and marketing
arrangements with Bayer Corporation and other companies such as Elensys Care
Services, Inc. ("Elensys") and MGI.
 
  Schein's objective is to become the leading generic pharmaceutical company in
the approximately $10 billion generic pharmaceutical industry in the United
States. The Company's strategy for achieving this objective comprises the
following five elements:
 
  Leverage Diverse Pharmaceutical Formulation and Manufacturing Capabilities to
Extend the Breadth of Its Generic Product Line. The Company believes it
manufactures and markets the broadest product line of any U.S. pharmaceutical
company. This product line includes both solid dosage and sterile dosage
products comprising approximately 160 chemical entities in approximately 350
dosage forms and strengths under approximately 200 approved ANDAs. Solid dosage
forms include both immediate-release and extended-release capsules and tablets;
sterile dosage forms include solutions, suspensions, powders and lyophilized
(freeze-dried) products primarily for administration as injections, ophthalmics
and otics. The Company believes its diverse high-volume manufacturing
capabilities enable it to participate in segments of the generic drug industry
where competition is limited. As the U.S. generic drug market consolidates and
major drug buyers increasingly purchase from fewer suppliers, the Company
believes its high volume and diverse drug formulation and manufacturing
capabilities will constitute an important competitive advantage.
 
  Pursue Strategic Collaborations to Supplement Product Development and
Manufacturing Resources. Schein has formed product development and marketing
alliances with several bulk pharmaceutical producers, drug delivery technology
companies and other drug manufacturers to expand the breadth of its product
development capabilities. Included among these are collaborations with drug
delivery companies, Elan and Ethical, and several bulk pharmaceutical and
finished dosage form producers. The Company plans to utilize collaborative and
licensing arrangements with third parties to share product development risk and
gain access to sales and marketing rights, dosage forms, proprietary drug
delivery technologies, specialized formulation capabilities and active
pharmaceutical ingredients.
 
                                       2

  Focus Product Development on Complex and Other Generic Drugs that Require
Specialized Development or Manufacturing Technology and Encounter Limited
Competition. The Company targets generic drugs for which it believes it can
achieve relatively high margins by being the first or among the first generic
manufacturers to launch the product. The Company is currently the sole generic
source for 47 products, and the Company is developing several "complex generic"
drugs that are difficult to duplicate due to formulation and/or manufacturing
complexities and other generic drugs for which raw materials are in limited
supply. In addition, the Company closely analyzes pharmaceutical patents and
initiates patent challenges where appropriate opportunities exist. Products
currently being considered for development include several that could lead to
patent challenges. The Company has generated significant revenues and profits
from generic products that have been the subject of successful patent
challenges initiated by the Company.
 
  Develop and Market Branded Drugs for Select Therapeutic
Categories. Leveraging its broad pharmaceutical formulation, development and
manufacturing capabilities, the Company targets branded drug development and
marketing opportunities in select therapeutic categories with limited
competition. The Company's branded drug development and marketing efforts
currently focus on injectable products used in the management of iron-related
disorders. The Company's first branded product, INFeD, is the leading
injectable iron product in the U.S. Schein's near-term development plan is to
expand the Company's iron management expertise into the oncology, hematology
and gastroenterology markets, and the Company expects that a New Drug
Application ("NDA") for its next generation injectable iron product will be
filed with FDA in the first half of 1998. The Company also is pursuing
opportunities to broaden its branded pharmaceutical product line by: (i)
formulating and developing, either internally or through development
collaborations, unique products that may be patented; (ii) acquiring products
developed by other drug companies; and (iii) acquiring formulation technologies
for developing new dosage forms of existing drugs.
 
  Expand Market Penetration through Direct Sales and Innovative Marketing
Programs. The Company believes its 120-person direct sales and marketing force
is the largest in the U.S. generic pharmaceutical industry. This sales and
marketing force includes 90 field representatives, 20 telemarketing
representatives and 10 marketing personnel and covers all major customer
groups, including chain and independent drug retailers, managed care
organizations, pharmaceutical wholesalers, hospitals and group purchasing
organizations. The Company has developed market share initiatives with selected
leading chain and wholesale customers and developed and implemented customized
marketing programs to meet specific customer needs, including customer
inventory management, patient-focused education and compliance programs. With
respect to its branded product business, the Company has a team of
approximately 20 sales representatives dedicated to marketing INFeD. This sales
and marketing force is complemented by marketing collaborations with Bayer (as
defined herein) in the nephrology market and MGI in the oncology market.

                              Guarantees."
 
Ranking.....................  The indebtedness evidenced by the Notes will be
                              senior unsecured obligations of the Company, will
                              rank pari passu with all existing and future
                              senior indebtedness of the Company and will rank
                              senior in right of payment to all existing and
                              future indebtedness of the Company that is, by
                              its terms, expressly subordinated to the Notes.
                              Holders of secured indebtedness of the Company,
                              including the lenders under the Senior Credit
                              Agreement, will have claims with respect to the
                              assets constituting collateral for such
                              indebtedness that are prior to the claims of
                              holders of the Notes. In the event of a default
                              on the Notes, or a bankruptcy, liquidation or
                              reorganization of the Company, such assets will
                              be available to satisfy obligations with respect
                              to the indebtedness secured thereby before any
                              payment therefrom could be made on the Notes. To
                              the extent that such collateral is not sufficient
                              to satisfy the indebtedness secured thereby,
                              amounts remaining outstanding on such
                              indebtedness would be entitled to share with the
                              Notes and their claims with respect to any other
                              assets of the Company. As of September 27, 1997,
                              as adjusted for the Offering, the Company and its
                              Restricted

                              Subsidiaries would have had secured indebtedness
                              of approximately $160.6 million outstanding. The
                              obligations of the Company and the Guarantors
                              under the Senior Credit Agreement are secured by
                              substantially all of the assets of the Company
                              and the Guarantors. As of September 27, 1997, as
                              adjusted for the Offering, the Company would have
                              had approximately $69.8 million of undrawn
                              availability under the Senior Credit Agreement.
                              The Indenture relating to the Notes will permit
                              the Company and the Restricted Subsidiaries to
                              incur additional Indebtedness, including Secured
                              Indebtedness, subject to certain limitations. See
                              "Description of Notes."
 
Change of Control...........  Upon a Change of Control, each holder of Notes
                              may require the Company to repurchase any or all
                              outstanding Notes owned by such holder at 101% of
                              the principal amount thereof, plus accrued and
                              unpaid interest thereon, to the date of
                              repurchase. See "Description of Notes--Change of
                              Control."
 
Restrictive Covenants.......  The Indenture under which the Notes will be
                              issued will contain certain covenants pertaining
                              to the Company and its Restricted Subsidiaries,
                              including but not limited to covenants with
                              respect to the following matters: (i) limitations
                              on indebtedness; (ii) limitations on restricted

                              subordinated obligations and investments; (iii)
                              limitations on liens; (iv) limitations on
                              engaging in certain lines of business; (v)
                              limitations on mergers, consolidations and
                              transfers of all or substantially all assets;
                              (vi) limitations on restrictions on distributions
                              from restricted subsidiaries; (vii) limitations
                              on sales of assets and of stock of subsidiaries;
                              (viii) limitations on transactions with
                              affiliates; (ix) limitations on the sale of
                              capital stock of restricted subsidiaries; and (x)
                              limitations on sale and leaseback transactions.
                              However, all of these covenants are subject to a
                              number of important qualifications and
                              exceptions. See "Description of Notes--Certain
                              Covenants."

Exchange Offer and

                              declared effective within the earlier of (A) 90
                              days after the Issue Date or (B) 30 days after
                              the effectiveness of the consummation of the

                              laws or interpretations of the staff of the
                              Commission do not permit the Company to effect
                              the Registered Exchange Offer, the Company will
                              use commercially reasonable efforts to cause to
                              become effective a shelf registration statement
                              (the "Shelf Registration Statement") with respect
                              to the resale of Notes and to keep the Shelf
                              Registration Statement effective until three
                              years from the Issue Date or such shorter period
                              that will terminate when all the Notes covered by
                              the Shelf Registration Statement have been sold.
                              The Company shall cause such Shelf Registration
                              Statement to be declared effective on or prior to
                              the latter of (x) the 120th day after the Issue

                              Notes. See "Exchange and Registration Rights
                              Agreement."
                             
Transfer Restrictions;       
 Absence of a Public Market  
 for the Notes..............  The Notes have not been registered under the
                              Securities Act and are subject to restrictions on
                              transferability and resale. The Notes are new
                              securities, and there is currently no established
                              market for the Notes. If issued, the Exchange
                              Notes will generally be freely transferable
                              (subject to the restrictions discussed elsewhere
                              herein) but will be new securities for which
                              there will not initially be a market.
                              Accordingly, there can be no assurance as to the
                              development or liquidity of any market for the
                              Notes or, if issued, the Exchange Notes. The
                              Notes have been designated eligible for trading
                              in the PORTAL market. The Initial Purchaser has
                              advised the Company that it currently intends to
                              make a market in the Notes. However, the Initial
                              Purchaser is not obligated to do so, and any
                              market making with respect to the Notes may be
                              discontinued at any time without notice. The
                              Company does not intend to apply for a listing of
                              the Notes, or, if issued, the Exchange Notes, on
                              any securities exchange or on any automated
                              dealer quotation system. See "Transfer
                              Restrictions."
 
Use of Proceeds.............  The Company is amending the terms of the Senior
                              Subordinated Loan Agreement (as defined herein)
                              to allow for the issuance of the Notes and
                              intends to use the net proceeds of the Offering
                              to repay the Senior Subordinated Loan (as defined
                              herein). See "Use of Proceeds."
 
                                  RISK FACTORS
 
  Prospective purchasers of the Notes should carefully consider the information
set forth under the caption "Risk Factors" and all other information set forth
in this Offering Memorandum before making any investment in the Notes.

(1) Includes the results of Marsam from September 1995, the date of purchase.
    In connection with the purchase of Marsam, the Company recognized acquired
    in-process research and development. See "Management's Discussion and
    Analysis of Financial Condition and Results of Operations" and Note 3 to
    the Consolidated Financial Statements of the Company.
(2) Special compensation, restructuring and relocation expenses includes costs
    recognized by the Company in connection with its restructuring and
    relocation of its corporate headquarters. See "Management's Discussion and
    Analysis of Financial Condition and Results of Operations" and Notes 2 and
    12 to the Consolidated Financial Statements of the Company.
(3) Other expense (income), net in 1992 includes $0.5 million of an
    extraordinary income item.
(4) Provision for income taxes in 1993 includes an adjustment to reduce income
    taxes by $1.1 million relating to the adoption of Statement of Financial
    Accounting Standards No. 109.
(5) EBITDA is defined as income (loss) before provision for income taxes and
    minority interest, interest expense, net and depreciation and amortization,
    excluding gains on sales of securities and non-cash items (special
    compensation, acquired in-process Marsam research and development,
    contingent settlement accruals, equity in net losses of international
    investments and other non-cash items). The Company has included information
    concerning EBITDA in this Offering Memorandum because it believes that such
    information may be used by certain investors as one measure of a company's
    historical ability to service debt. EBITDA should not be considered as an
    alternative to, or more meaningful than, earnings from operations or other
    traditional indications of a company's operating performance.
(6) The ratio of earnings to fixed charges is computed by dividing (i) income
    (loss) before provision for income taxes and minority interest plus fixed
    charges by (ii) fixed charges. Fixed charges consist of interest on
    indebtedness including amortization of debt issuance costs and the
    estimated interest component of rental expense (assumed to be one-third).
    In fiscal 1995, fixed charges exceeded income (loss) before provision for
    income taxes and minority interest by $4.4 million.
(7) Pro forma cash interest expense is defined as historical interest expense,
    net adjusted for (i) the exclusion of amortization of deferred financing
    fees of $2.2 million in fiscal 1996 and $0.9 million and $2.3 million in
    the nine months ended September 1996 and 1997, respectively, (ii) interest
    expense as if the Offering had occurred on December 31, 1995 and the
    proceeds were used to repay the Senior Subordinated Loan or its predecessor
    debt and (iii) interest expense associated with drawdowns under the
    revolving credit facility under the Senior Credit Agreement which were used
    to pay the $4.2 million in fees and expenses incurred as a result of the
    Offering.
(8) The ratio of total debt to EBITDA (as defined) is computed by dividing (i)
    EBITDA (as defined) for the twelve months ended September 1997 by (ii)
    total debt as of September 1997 as adjusted for the Offering.
(9) As adjusted to give effect to the Offering and the payment of $4.2 million
    in fees and expenses in connection therewith, using proceeds from the
    Company's revolving credit facility under the Senior Credit Agreement.

                                 RISK FACTORS
 
  Prospective investors in the Notes should carefully consider the following
risk factors, in addition to the other information set forth in this Offering
Memorandum, before making an investment in the Notes offered hereby. This
Offering Memorandum contains statements which constitute forward-looking
statements within the meaning of the Private Securities Litigation Reform Act
of 1995. Those statements appear in a number of places herein and include
statements regarding the intent, belief or current expectations of the
Company, primarily with respect to the future operating performance of the
Company or related industry developments. Prospective purchasers of the Notes
are cautioned that any such forward-looking statements are not guarantees of
future performance and involve risks and uncertainties, and that actual
results and industry developments may differ from those described in the
forward-looking statements as a result of various factors, many of which are
beyond the control of the Company. The information contained herein,
including, without limitation, the information set forth below and the
information under the heading "Management's Discussion and Analysis of
Financial Condition and Results of Operations," identifies important factors
that could cause such differences.
 
RISK FACTORS RELATED TO THE NOTES
 
 Substantial Leverage
 
  The Company is highly leveraged. As of September 27, 1997, as adjusted for
the Offering, the Company would have had total consolidated indebtedness of
$260.6 million. In addition, subject to certain restrictions set forth in the
Senior Credit Agreement and the Indenture, the Company may incur additional
indebtedness in the future for acquisitions, capital expenditures and other
corporate purposes.
 
  The Company's high degree of leverage could have important consequences,
including the following: (i) the Company's ability to obtain additional
financing in the future for working capital, capital expenditures,
acquisitions, general corporate purposes or other purposes may be impaired;
(ii) a substantial portion of the Company's cash flow from operations must be
dedicated to the payment of principal and interest on the Notes and its other
indebtedness, thereby reducing the funds available to the Company for other
purposes; (iii) the financial covenants and other restrictions contained in
the Senior Credit Agreement and the Indenture and other agreements relating to
the Company's indebtedness require the Company to meet certain financial
tests, restrict its ability to borrow additional funds and impose limitations
on the disposition of assets; (iv) obligations in respect of the Senior Credit
Agreement are, and the Notes will be, and other indebtedness of the Company
may be, at variable rates of interest, which expose the Company to the risk of
increased interest rates; (v) all of the indebtedness outstanding under the
Senior Credit Agreement is secured by substantially all the assets of the
Company and matures prior to the maturity of the Notes; (vi) the Company may
be substantially more leveraged than certain of its competitors, which may
place the Company at a competitive disadvantage; and (vii) the Company's
substantial degree of leverage may limit its flexibility to adjust to changing
market conditions and make it more vulnerable to a downturn in general
economic conditions or its business. See "Description of Notes."
 
  The Company's ability to make scheduled payments of the principal of, or
interest on, or to refinance its indebtedness (including the Notes) depends on
its future operating performance, which to a certain extent is subject to
economic, financial, competitive and other factors beyond its control. The
Company believes that, based on its current level of operations and
anticipated growth, its cash flow from operations will be adequate to meet its
anticipated requirements for working capital, capital expenditures, interest
payments and scheduled principal payments over the next several years. There
can be no assurance, however, that the Company's business will generate cash
flow at or above expected levels. If the Company is unable to generate
sufficient cash flow from operations in the future to service its debt, fund
working capital requirements and make necessary capital expenditures, or its
future earnings are insufficient to make all required principal payments out
of internally generated funds, the Company may be required to refinance all or
a portion of its existing debt, sell assets or obtain additional financing.
There can be no assurance that any such refinancing or asset sales would be
possible or that any additional financing could be obtained on terms
acceptable to the Company or at all, particularly in
 
                                       9
<PAGE>
 
view of the Company's high level of debt. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources."
 
 Ability to Service Debt
 
  The Company's ability to make scheduled payments or to refinance its
obligations with respect to its indebtedness will depend on its financial and
operating performance, which in turn will be subject to prevailing economic
conditions and to certain financial, business and other factors beyond its
control. If the Company's cash flow and capital resources are insufficient to
fund its debt service obligations, the Company may be forced to reduce or
delay planned expansion and capital expenditures, sell assets, obtain
additional equity capital or restructure its debt. There can be no assurance
that the Company's operating results, cash flow and capital resources will be
sufficient for payment of its indebtedness in the future. In the absence of
such operating results and resources, the Company could face substantial
liquidity problems and might be required to dispose of material assets or
operations to meet its debt service and other obligations, and there can be no
assurance as to the timing of such sales or the proceeds that the Company
could realize therefrom. In addition, because the Notes will bear interest at
floating rates and the Senior Credit Agreement bears interest at floating
rates, an increase in interest rates could adversely affect, among other
things, the Company's ability to meet its debt service obligations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources" and "Description of Notes."
 
 Ranking of Notes
 
  The Notes will be senior unsecured obligations of the Company and will rank
pari passu in right of payment with all current and future unsecured senior
indebtedness of the Company. The Notes will (i) rank senior in right of
payment to all subordinated indebtedness of the Company and (ii) be
guaranteed, on a senior unsecured basis, by the Restricted Subsidiaries of the
Company. The Notes will also be effectively subordinated to all existing and
future indebtedness of any subsidiary of the Company that is not a Guarantor
of the Notes.
 
  The indebtedness incurred under the Senior Credit Agreement is secured by
substantially all of the assets of the Company. In addition, the Indenture
will permit the Company and the Guarantors to incur certain other secured
indebtedness. The holders of all existing and future secured indebtedness will
have a claim prior to the holders of the Notes with respect to any assets
pledged by the Company and the Guarantors as security for such indebtedness.
Further, as of September 27, 1997, as adjusted for the Offering, the Senior
Credit Agreement would have provided the Company with $69.8 million of undrawn
availability, which, if drawn, would effectively rank prior to the Notes and
the Subsidiary Guarantees. Upon an event of default under the Senior Credit
Agreement, the lenders thereunder would be entitled to foreclose on the assets
of the Company and the Guarantors pledged as security for the indebtedness
incurred thereunder. In such event, the assets of the Company and the
Guarantors remaining after payment of such secured indebtedness may be
insufficient to satisfy the obligations of the Company and the Guarantors with
respect to the Notes and the Subsidiary Guarantees. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources" and "Description of Notes."
 
  As of September 27, 1997, as adjusted for the Offering, the aggregate
principal amount of secured indebtedness of the Company and the Guarantors
which would have effectively ranked senior to the Notes and the Subsidiary
Guarantees would have been approximately $160.6 million.
 
 Fraudulent Conveyance
 
  The issuance of the Notes and the Subsidiary Guarantees may be subject to
review by a court under federal bankruptcy law or comparable provisions of
state fraudulent transfer law. Under federal or state fraudulent transfer
laws, if a court were to find that, at the time the Notes and Subsidiary
Guarantees were issued, the Company or a Guarantor, as the case may be, (i)
issued the Notes or a Subsidiary Guarantee with the intent of hindering,
delaying or defrauding current or future creditors or (ii)(A) received less
than fair consideration or reasonably equivalent value for incurring the
indebtedness represented by the Notes or a Subsidiary Guarantee
 
                                      10
<PAGE>
 
and (B)(1) was insolvent or was rendered insolvent by reason of the issuance
of the Notes or such Subsidiary Guarantee, (2) was engaged, or about to
engage, in a business or transaction for which its remaining assets
constituted unreasonably small capital or (3) intended to incur, or believed
(or should have believed) it would incur, debts beyond its ability to pay as
such debts mature (as all of the foregoing terms are defined in or interpreted
under such fraudulent transfer statutes), such court could avoid all or a
portion of the Company's or a Guarantor's obligations to the holders of the
Notes or subordinate the Company's or a Guarantor's obligations to the holders
of the Notes to other existing and future indebtedness of the Company or such
Guarantor, as the case may be, the effect of which would be to entitle such
other creditors to be paid in full before any payment could be made on the
Notes, and take other action detrimental to the holders of the Notes,
including in certain circumstances, invalidating the Notes. In that event,
there would be no assurance that any repayment on the Notes would ever be
recovered by the holders of the Notes.
 
  The definition of insolvency for purposes of the foregoing considerations
varies among jurisdictions depending upon the federal or state law that is
being applied in any such proceeding. However, the Company or a Guarantor
generally would be considered insolvent at the time it incurs the indebtedness
constituting the Notes or a Subsidiary Guarantee, as the case may be, if (i)
the fair market value (or fair saleable value) of its assets is less than the
amount required to pay its total existing debts and liabilities (including the
probable liability on contingent liabilities) as they become absolute or
matured or (ii) it is incurring debts beyond its ability to pay as such debts
mature.
 
  There can be no assurance as to what standard a court would apply in order
to evaluate the parties' intent or to determine whether the Company or a
Guarantor, as the case may be, was insolvent at the time, or rendered
insolvent upon consummation, of the sale of the Notes or the issuance of a
Subsidiary Guarantee or that, regardless of the method of valuation, a court
would not determine that the Company or a Guarantor, as the case may be, was
insolvent at the time, or rendered insolvent upon consummation, of the
Offering. Nor can there be any assurance that a court would not determine,
regardless of whether the Company or a Guarantor was insolvent on the date the
Notes and Subsidiary Guarantees were issued, that the payments constituted
fraudulent transfers on another ground.
 
  In addition, the Subsidiary Guarantees could also be subject to the claim
that, since the Subsidiary Guarantees were incurred for the benefit of the
Company (and only indirectly for the benefit of the Guarantors), the
obligations of the Guarantors thereunder were incurred for less than
reasonably equivalent value or fair consideration. A court could avoid a
Guarantor's obligation under its Subsidiary Guarantee, subordinate the
Subsidiary Guarantee to other indebtedness of such Guarantor or take other
action detrimental to the holders of the Notes.
 
 Restrictions Imposed by Terms of the Company's Indebtedness
 
  The Indenture will contain certain covenants that, among other things: (i)
limit the ability of the Company and its Restricted Subsidiaries to incur
additional indebtedness, repay other indebtedness and amend other debt
instruments; (ii) restrict the ability of the Company and its Restricted
Subsidiaries to make dividends and other restricted payments (including
investments); (iii) limit the ability of the Company and its Restricted
Subsidiaries to incur certain liens; (iv) limit the ability of the Company to
engage in other lines of business; (v) limit the ability of the Company to
consolidate or merge with or into, or to sell, assign, transfer, lease, convey
or otherwise dispose of all or substantially all of its assets to, another
person; (vi) limit the ability of the Restricted Subsidiaries to create
restrictions on the payment of dividends and other payments; (vii) limit the
ability of the Company and its Restricted Subsidiaries to make sales of assets
and stock of a subsidiary; (viii) limit transactions by the Company and its
Restricted Subsidiaries with affiliates; (ix) limit the sale of capital stock
of Restricted Subsidiaries; and (x) limit the ability of the Company and its
Restricted Subsidiaries to enter into sale and leaseback transactions. In
addition, the Senior Credit Agreement also contains certain other restrictive
covenants which are generally more restrictive than those contained in the
Indenture and limit the Company's ability to prepay its other indebtedness
(including the Notes). The Senior Credit Agreement also requires the Company
to maintain specified consolidated financial ratios and satisfy certain
consolidated financial tests. See "Description of Certain Indebtedness" and
"Description of Notes."
 
                                      11
<PAGE>
 
  The Company's ability to comply with the covenants in the Indenture and the
Senior Credit Agreement may be affected by events beyond its control,
including prevailing economic, financial, competitive, legislative, regulatory
and other conditions. The breach of any such covenants or restrictions could
result in a default under the Indenture and/or the Senior Credit Agreement,
which would permit the holders of the Notes and/or the lenders under the
Senior Credit Agreement, as the case may be, to declare all amounts borrowed
thereunder to be due and payable, together with accrued and unpaid interest,
and the commitments of the lenders to make further extensions of credit under
the Senior Credit Agreement could be terminated. If the Company was unable to
repay its indebtedness to the lenders under the Senior Credit Agreement, such
lenders could proceed against any or all of the collateral securing the
indebtedness under the Senior Credit Agreement, which collateral will consist
of substantially all of the assets of the Company and the Guarantors. In
addition, if the Company fails to comply with the financial and operating
covenants contained in the Senior Credit Agreement, such failure could result
in an event of default thereunder, which could permit the acceleration of the
debt incurred thereunder and, in some cases, cross-acceleration and cross-
default of indebtedness outstanding under other debt instruments of the
Company, including the Notes. See "Description of Notes."
 
 Limitation on Change in Control
 
  Upon a Change of Control, the Company will be required to offer to purchase
all of the outstanding Notes at a price equal to 101% of the principal amount
thereof plus accrued and unpaid interest thereon to the date of repurchase.
 
  The Senior Credit Agreement also provides that certain change of control
events with respect to the Company constitute a default thereunder. Any future
credit agreements or other agreements to which the Company becomes a party may
contain similar restrictions and provisions. In the event a Change of Control
occurs at a time when the Company is prohibited from purchasing the Notes, or
if the Company is required to make an asset sale offer pursuant to the terms
of the Notes, the Company could seek the consent of its lenders to purchase
the Notes or could attempt to refinance the borrowings that contain such
prohibition. If the Company does not obtain such a consent or refinance such
borrowings, the Company will remain prohibited from purchasing the Notes. In
such case, the Company's failure to purchase tendered Notes would constitute
an Event of Default as defined under the Indenture. If, as a result thereof, a
default occurs with respect to any other senior indebtedness, payments to the
holders of the Notes could be limited.
 
  In addition, the Change of Control provisions may not be waived by the Board
of Directors of the Company or the Trustee without the consent of holders of
at least a majority in principal amount of the Notes. As a result, the Change
of Control provisions of the Notes may in certain circumstances discourage or
make more difficult a sale or takeover of the Company and, thus, the removal
of incumbent management. See "Description of Notes--Change of Control."
 
 Lack of Public Market; Restrictions on Transferability
 
  The Company does not intend to apply for a listing of the Notes, or if
issued, the Exchange Notes, on any securities exchange or on any automated
dealer quotation system. There is currently no established market for the
Notes, and there can be no assurance as to the liquidity of markets that may
develop for the Notes, the ability of the holders of the Notes to sell their
Notes or the price at which such holders would be able to sell their Notes. If
such market were to exist, the Notes could trade at prices that may be lower
than the initial market values thereof depending on many factors, including
prevailing interest rates, the Company's operating results and the market for
similar securities. The Notes are expected to be designated for trading in the
PORTAL market. The Initial Purchaser has advised the Company that it currently
intends to make a market with respect to the Notes. However, the Initial
Purchaser is not obligated to do so, and any market making with respect to the
Notes may be discontinued at any time without notice. In addition, such market
making activity will be subject to the limits imposed by the Securities Act
and the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
may be limited during the pendency of the Exchange Offer or the effectiveness
of a shelf registration statement in lieu thereof. See "Exchange and
Registration Rights Agreement," "Transfer Restrictions" and "Plan of
Distribution."
 
                                      12
<PAGE>
 
  The Notes are being offered in reliance upon an exemption from registration
under the Securities Act and applicable state securities laws. Therefore, the
Notes may be transferred or resold only in a transaction registered under or
exempt from the Securities Act and applicable state securities laws. Pursuant
to the Exchange and Registration Rights Agreement, the Company and the
Guarantors have agreed to file the Exchange Offer Registration Statement with
the Commission and to use their best efforts to cause such registration
statement to become effective with respect to the Exchange Notes. If issued,
the Exchange Notes generally will be permitted to be resold or otherwise
transferred by each holder without the requirement of further registration.
The Exchange Notes, however, also will constitute a new issue of securities
with no established trading market. The Exchange Offer will not be conditioned
upon any minimum or maximum aggregate principal amount of Notes being tendered
for exchange. No assurance can be given as to the liquidity of the trading
market for the Exchange Notes, or, in the case of non-exchanging holders of
Notes, the trading market for the Notes following the Exchange Offer. See
"Exchange and Registration Rights Agreement."
 
  The liquidity of, and trading market for, the Notes or the Exchange Notes
also may be adversely affected by a general decline in the market for similar
securities. Such a decline may adversely affect such liquidity and trading
markets independent of the financial performance of, and prospects for, the
Company.
 
RISK FACTORS RELATED TO THE COMPANY'S OPERATIONS
 
 Dependence Upon New Products and Effect of Product Lifecycles
 
  The Company's results of operations depend, to a significant extent, upon
its ability to develop and commercialize new pharmaceutical products in
response to the competitive dynamics within the pharmaceutical industry.
Generally, following the expiration of patents and any other market
exclusivity periods for branded drugs, the first pharmaceutical manufacturers
successfully to market generic equivalents of such drugs achieve higher
revenues and gross profit from the sale of such generic drugs than do others
from the sale of generic equivalents subsequently approved. As competing
generic products reach the market, the prices, sales volumes and profit
margins of the first generic versions often decline significantly. For these
reasons, the Company's ability to achieve growth in revenues and profitability
depends on its being among the first companies regularly to introduce new
generic products. While the Company believes the pipeline of generic drugs and
branded drugs it currently has under development will allow it to compete
effectively, no assurance can be given that any of the drugs in its pipeline
will be successfully developed or approved by FDA, will be among the first to
the market or will achieve significant revenues and profitability. See "--
Dependence on Successful Patent Litigation," "--Competition," "--Dependence on
Regulatory Approval and Compliance," "--Pending Regulatory Matters,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business."
 
 Dependence on Certain Existing Products
 
  The Company derives and is expected to continue to derive a significant
portion of its revenues and gross profit from a limited number of products.
Net revenues from INFeD in 1996 and the nine months ended September 1997 were
$88.0 million and $72.1 million, respectively, or 19% and 20%, respectively,
of the Company's total net revenues, with gross profit from INFeD as a
percentage of total gross profit being significantly greater. Any material
decline in revenues or gross profit from these products could have a material
adverse effect on the Company's business, results of operations and financial
condition. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and "Business--Products."
 
 Dependence on Successful Patent Litigation
 
  A significant portion of the Company's revenues and gross profit has been
derived from generic versions of branded drug products covered by patents the
Company has challenged under the Drug Price Competition and Patent Term
Restoration Act of 1984 (the "Waxman-Hatch Act"). In several successful
proceedings, the Company has been advised and represented by an independent
patent attorney (the "Consultant") whose involvement has been substantial. The
Company expects that the Consultant will be involved with the Company
 
                                      13
<PAGE>
 
in no more than two additional patent challenges, one of which is currently
being litigated. Through its internal efforts, and with the assistance of
third-party collaborators and advisors, the Company has identified a number of
additional patents that may be susceptible to challenge. There can be no
assurance the Company will successfully complete the development of any
additional products involving patent challenges, succeed in any pending or
future patent challenges or, if successful, receive significant revenues or
profit from the products covered by successfully challenged patents. See "--
Dependence Upon New Products and Effect of Product Lifecycles," "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
"Business--Government Regulations" and "Certain Transactions."
 
 Competition
 
  The pharmaceutical industry is intensely competitive. The Company competes
with numerous companies in the pharmaceutical industry generally and the
generic segment of the industry specifically. These competitors include
generic drug manufacturers and large pharmaceutical companies that continue to
manufacture the branded and/or generic versions of drugs after the expiration
of their patents relating to these drugs. Many of the Company's competitors
have greater financial and other resources than the Company and, therefore,
are able to spend more than the Company on research, product development and
marketing. In addition, following the expiration of patents on branded drugs,
manufacturers of these products have employed various strategies intended to
maximize their share of the markets for these products, as well as, in some
cases, generic equivalents of these products, and are expected to continue to
do so in the future. There can be no assurance that developments by others
will not render any product the Company produces or may produce obsolete or
otherwise non-competitive. See "--Dependence Upon New Products and Effect of
Product Lifecycles," "--Consolidation of Distribution Network; Customer
Concentration" and "Business--Competition."
 
 Dependence on Regulatory Approval and Compliance
 
  The development, manufacture, marketing and sale of pharmaceutical products
is subject to extensive federal, state and local regulation in the U.S. and
similar regulation in other countries. The Company, like its competitors, must
obtain approval from FDA before marketing most drugs, and must demonstrate
continuing compliance with current Good Manufacturing Practices ("cGMP")
regulations. Generally, for generic products an ANDA is submitted to FDA, and
for new drugs an NDA is submitted. Under certain circumstances following
product approval and market introduction, FDA can request product recalls,
seize inventories and merchandise in commerce, move to enjoin further
manufacture and product distribution, suspend distribution or withdraw FDA
approval of the product, and debar a company from submitting new applications.
FDA also can take administrative action against a company to suspend
substantive review of pending applications and withhold approvals, if it
concludes that the data and applications from that company may not be reliable
or that there are significant unresolved cGMP issues pertinent to the
manufacture of drugs at a particular facility of that company. Any such
actions are likely to have a material adverse effect on a company's business.
The Company has ANDAs currently pending before FDA and intends to file
additional ANDAs in the future. Delays in the review of these applications or
the inability of the Company to obtain approval of certain of these
applications or to market the product following approval could have a material
adverse effect on the Company's business, results of operations and financial
condition. See "--Dependence Upon New Products and Effect of Product
Lifecycles," "--Pending Regulatory Matters" and "Business--Government
Regulations."
 
 Pending Regulatory Matters
 
  In early 1996, FDA conducted an inspection of the operations of the
Company's subsidiary, Steris Laboratories, Inc. ("Steris"), located in
Phoenix, Arizona. At the conclusion of that inspection, FDA identified various
cGMP manufacturing and reporting deficiencies in Steris' operations. Steris
has subsequently been advised by FDA that it will not approve any ANDAs for
products manufactured at the Steris facility until FDA confirms that the
manufacturing and reporting deficiencies have been corrected. Ten of the
Company's pending ANDAs have been filed from the Steris facility. Following
the 1996 inspection, Steris implemented numerous measures to correct these
deficiencies and place Steris in compliance with applicable FDA manufacturing
and reporting requirements.
 
                                      14
<PAGE>
 
  In July 1997, FDA conducted a follow-up inspection of the Steris facility.
At the conclusion of that inspection, FDA identified additional cGMP
deficiencies at the Steris facility. Steris has implemented measures intended
to correct these deficiencies and believes that a full reinspection will be
required before FDA will approve ANDAs for new products manufactured at the
Steris facility. While the Company is currently discussing with FDA the timing
of this reinspection, no assurance can be given as to when it will take place.
 
  Following the 1996 inspection of Steris, FDA's Office of Regulatory Affairs
staff commenced an investigation of Steris' operations that focused primarily
on drug stability issues, including Steris' alleged failure to notify FDA on
an adequate and timely basis of drug stability problems with respect to
certain products manufactured at the Steris facility. On the basis of this
investigation, the U.S. Department of Justice ("DOJ") notified Steris in a
letter dated July 28, 1997 that the alleged reporting deficiencies constituted
serious breaches of regulatory obligations and indicated that it would be
willing to negotiate a settlement of the alleged violations with Steris. The
contemplated settlement will require Steris to pay a substantial misdemeanor
fine for failure to observe application reporting requirements for two drugs
during 1994 and 1995. While the Company does not expect any other sanctions to
arise in respect of this matter, any such sanctions could have a material
adverse effect on the Company's business, results of operations and financial
condition.
 
  In 1995, FDA inspected the operations of the Company's subsidiary, Danbury
Pharmacal, Inc. ("Danbury"), which operates facilities in Carmel, New York and
Danbury, Connecticut. As a result of observations made by FDA relating to
Danbury's compliance with cGMP requirements and the integrity of the data
submitted by Danbury in support of certain ANDAs, Danbury voluntarily audited
all data submitted in connection with 26 of its pending and approved ANDAs.
Since the 1995 inspection, FDA has continued to approve ANDAs for products
manufactured by Danbury. In August 1997, FDA reinspected the Carmel and
Danbury facilities. FDA observed certain cGMP deficiencies which the Company
has corrected in a manner satisfactory to FDA. FDA is currently conducting an
additional inspection of those facilities, which the Company believes
primarily will involve evaluations of the ANDA audits and the procedural
changes Danbury instituted to remedy cGMP deficiencies observed during the
1995 FDA inspection.
 
  In June 1997, FDA conducted an ANDA preapproval and cGMP inspection at the
Company's Marsam subsidiary, located in Cherry Hill, New Jersey. Although the
inspection focused primarily on issues relating to the manufacture of certain
drug products that are the subject of five pending ANDAs, the inspection also
included an examination of Marsam's general compliance with cGMP requirements.
Marsam was informed at the conclusion of the inspection that FDA intended to
withhold approval of the five ANDAs until certain alleged cGMP deficiencies
are corrected. Marsam has provided FDA with information it believes
demonstrates that the alleged deficiencies are not significant and that
corrective measures have been implemented. FDA has begun a follow-up
inspection to determine whether these corrective actions have been implemented
satisfactorily. Seven of the Company's pending ANDAs have been filed from the
Marsam facility.
 
  There can be no assurance that FDA will determine that the Company has
adequately corrected the alleged deficiencies or that approval of any of the
pending or subsequently submitted ANDAs by the Company will be forthcoming. In
addition, there can be no assurance that FDA, following the reinspection of
the Steris, Danbury and Marsam facilities and its review of their respective
responses to the alleged cGMP deficiencies, will not seek to impose additional
regulatory sanctions against the Company and its subsidiaries. See "--
Dependence Upon New Products and Effect of Product Lifecycles" and "Business--
Government Regulations."
 
 Consolidation of Distribution Network; Customer Concentration
 
  The Company's principal customers are wholesale drug distributors and major
drug store chains. These customers comprise a significant part of the
distribution network for pharmaceutical products in the United States. This
distribution network is continuing to undergo significant consolidation marked
by mergers and acquisitions among wholesale distributors and the growth of
large retail drug store chains. As a result, a small number of large wholesale
distributors control a significant share of the market, and the number of
independent drug stores and small drug store chains has decreased. The Company
expects that consolidation of drug
 
                                      15
<PAGE>
 
wholesalers and retailers will increase competitive pricing pressure on
generic drug manufacturers. The Company believes this consolidation has caused
and may continue to cause the Company's customers to reduce purchases of the
Company's products. For the nine months ended September 1997 and for the year
ended December 1996, sales to the Company's ten largest customers represented
approximately 70% of the Company's total net revenues. For the nine months
ended September 1997, three customers accounted for 17%, 16% and 11%,
respectively, of the Company's total net revenues. The same three customers
accounted for 16%, 15% and 11%, respectively, of the Company's total net
revenues in 1996. The loss of any of these customers could materially and
adversely affect the Company's business, results of operations and financial
condition. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and "Business--Industry Overview."
 
 Dependence on Collaborative Relationships
 
  The Company develops and markets certain products through collaborative
arrangements with other companies through which it gains access to dosage
forms, proprietary drug delivery technology, specialized formulation
capabilities and active pharmaceutical ingredients. The Company relies on its
collaborative partners for any number of functions, including product
formulation, approval and supply. There can be no assurance these products
will be successfully developed or that the Company's partners will perform
their obligations under these collaborative arrangements. Further, there can
be no assurance that the Company will be able to enter into future
collaborative arrangements on favorable terms, or at all. Even if the Company
enters into such collaborative arrangements, there can be no assurance that
any such arrangement will be successful. See "Business--Strategy" and
"Business--Strategic Collaborations."
 
 Supply of Raw Materials
 
  The principal components of the Company's products are active and inactive
pharmaceutical ingredients and certain packaging materials. Many of these
components are available only from a single source and, in many of the
Company's ANDAs, only one supplier of raw materials has been identified, even
in instances when multiple sources exist. Because FDA approval of drugs
requires manufacturers to specify their proposed suppliers of active
ingredients and certain packaging materials in their applications, FDA
approval of any new supplier would be required if active ingredients or such
packaging materials were no longer available from the specified supplier. The
qualification of a new supplier could delay the Company's development and
marketing efforts. Any interruption of supply could have a material adverse
effect on the Company's ability to manufacture its products or to obtain or
maintain regulatory approval of such products. In addition, the Company
obtains a significant portion of its raw materials from foreign suppliers.
Arrangements with international raw material suppliers are subject, among
other things, to FDA regulation, various import duties and other government
clearances. Acts of governments outside the U.S. may affect the price or
availability of raw materials needed for the development or manufacture of
generic drugs. In addition, recent changes in patent laws in jurisdictions
outside the U.S. may make it increasingly difficult to obtain raw materials
for research and development prior to the expiration of the applicable U.S.
patents. There can be no assurance that the Company will establish or, if
established, maintain good relationships with its suppliers or that such
suppliers will continue to exist or be able to supply ingredients in
conformity with legal or regulatory requirements. See "Business--Strategy" and
"Business--Manufacturing and Distribution."
 
 Risk of Product Liability Claims; No Assurance of Adequate Insurance
 
  The testing, manufacture and sale of pharmaceutical products involve a risk
of product liability claims and the adverse publicity that may accompany such
claims. The Company is a defendant in a number of product liability cases, the
outcome of which the Company believes should not materially and adversely
affect the Company's business, financial condition or results of operations.
Although the Company maintains what it believes to be an adequate amount of
product liability insurance coverage, there can be no assurance that the
Company's existing product liability insurance will cover all current and
future claims or that the Company will be able to maintain existing coverage
or obtain, if it determines to do so, insurance providing additional coverage
at reasonable rates. No assurance can be given that one or more of the claims
arising under any pending or future
 
                                      16
<PAGE>
 
product liability cases, whether or not covered by insurance, will not have a
material adverse effect on the Company's business, results of operations or
financial condition. See "Business--Product Liability; Insurance" and
"Business--Legal Proceedings."
 
 Control of the Company
 
  Several of the Company's current principal stockholders are parties to the
Restructuring Agreements (as defined herein), which govern the voting of their
common stock (the "Common Stock") until March 2000. The shares subject to
these agreements represent a majority of the shares of Common Stock
outstanding. Under these agreements, the voting trustee (currently Martin
Sperber, the Chairman of the Board, Chief Executive Officer and President of
the Company), has the right to vote, or direct the vote of, the shares subject
to these agreements. Accordingly, Mr. Sperber is able to control substantially
all matters requiring stockholder approval, including the election of
directors. These agreements remain in effect until March 2000, subject to
earlier termination under certain circumstances. Upon such termination, the
stockholders who are parties to these agreements may be able to control all
matters requiring stockholder approval, including the election of directors.
 
  Bayer Corporation, which owns 28.3% of the outstanding shares of Common
Stock, is a party to an agreement with the Company (the "Standstill") that,
among other things, prevents Bayer Corporation from acquiring or seeking to
acquire control of the Company until May 15, 2001. After such date, Bayer
Corporation has the right to acquire control through open market purchases,
and under certain circumstances within six months of the end of the
Standstill, to acquire from certain principal stockholders of the Company or
from the Company a number of shares that would enable Bayer Corporation to own
a majority of the outstanding shares of Common Stock. During the Standstill,
Bayer Corporation has, under the terms of the Restructuring Agreements, the
right to acquire, including under certain circumstances the right to acquire
from the Company and certain of its principal stockholders, a significant
number of additional shares of Common Stock.
 
  As long as Bayer Corporation owns 10% or more of the outstanding Common
Stock, Bayer Corporation has the right to nominate one member of the Company's
Board of Directors and the right to nominate one or more additional directors,
depending on the number of shares it owns. Until May 15, 2001, the Company may
not undertake certain actions without the consent of Bayer Corporation,
including, among other things, engaging in any business not principally in a
segment of the pharmaceutical or health care industry or amending the
Company's charter or by-laws to require more than majority approval to elect a
majority of the Board of Directors, merge, consolidate or sell all or
substantially all the Company's assets. In addition, until the shares of the
Company's Common Stock held by more than 300 persons who are neither current
stockholders, their permitted transferees nor employees of the Company have a
total market value in excess of $100.0 million, the Company may not undertake
certain other actions without the consent of Bayer Corporation.
 
  Each of the provisions described above may make it more difficult for a
third party to acquire, or may discourage acquisition bids for, Schein. See
"Management--Board of Directors" and "Certain Transactions--Restructuring
Agreements."
 
 Fluctuating Results of Operations
 
  During the past three years, the Company's results of operations have
fluctuated materially on both an annual and a quarterly basis. These
fluctuations have resulted from several factors, including, among others, the
timing of introductions of new products by the Company and its competitors,
timing of receipt of patent settlement revenues, dependence by the Company on
a limited number of products, certain non-recurring expenses related to the
Company's restructuring and relocation in 1994, the Marsam Acquisition (as
defined herein) in 1995 and weak performance by the generic drug industry in
the second half of 1996 and continuing into the first half of 1997. The
Company believes that it will continue to experience fluctuations in net
revenues, gross profit and net income as a result of, among other things, the
timing of regulatory approvals and market introduction of new products by the
Company and its competitors, and downward pressure on pricing for generic
products available from multiple approved sources. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

                                  THE COMPANY
 
  The Company was founded in 1985. From 1992 to 1994, the Company engaged in a
series of corporate reorganization transactions, including the separation of
the Company from Henry Schein, Inc., a company engaged in the direct marketing
of health care products and services to office-based health care
practitioners, and the Company's reincorporation from New York to Delaware by
way of the merger of the Company's parent into the Company. In 1994, Bayer
Corporation purchased 28.3% of the Company's outstanding shares and agreed to
pursue future strategic alliances with the Company. In September 1995, the
Company acquired all the outstanding shares of Marsam, a developer,
manufacturer and marketer of generic injectable prescription drugs.
 
  The Company is a Delaware corporation with its corporate offices at 100
Campus Drive, Florham Park, New Jersey 07932. Its telephone number is (973)
593-5500.

    In connection with the purchase of Marsam, the Company recognized acquired
    in-process research and development. See "Management's Discussion and
    Analysis of Financial Condition and Results of Operations" and Note 3 to
    the Consolidated Financial Statements of the Company.
(2) Special compensation, restructuring and relocation expenses includes costs
    recognized by the Company in connection with its restructuring and

(4) Provision for income taxes in 1993 includes an adjustment to reduce income
    taxes by $1.1 million relating to the adoption of Statement of Financial
    Accounting Standards No. 109.
(5) EBITDA is defined as income (loss) before provision for income taxes and
    minority interest, interest expense, net and depreciation and
    amortization, excluding gains on sales of securities and non-cash items
    (special compensation, acquired in-process Marsam research and
    development, contingent settlement accruals, equity in net losses of
    international investments and other non-cash items). The Company has
    included information concerning EBITDA in this Offering Memorandum because
    it believes that such information may be used by certain investors as one
    measure of a company's historical ability to service debt. EBITDA should
    not be considered as an alternative to, or more meaningful than, earnings
    from operations or other traditional indications of a company's operating
    performance.
(6) The ratio of earnings to fixed charges is computed by dividing (i) income
    (loss) before provision for income taxes and minority interest plus fixed
    charges by (ii) fixed charges. Fixed charges consist of interest on
    indebtedness including amortization of debt issuance costs and the
    estimated interest component of rental expense (assumed to be one-third).
    In fiscal 1995, fixed charges exceeded income (loss) before provision for
    income taxes and minority interest by $4.4 million.
(7) Pro forma cash interest expense is defined as historical interest expense,
    net adjusted for (i) the exclusion of amortization of deferred financing
    fees of $2.2 million in fiscal 1996 and $0.9 million and $2.3 million in
    the nine months ended September 1996 and 1997, respectively, (ii) interest
    expense as if the Offering had occurred on December 31, 1995 and the
    proceeds were used to repay the Senior Subordinated Loan or its
    predecessor debt and (iii) interest expense associated with drawdowns
    under the revolving credit facility under the Senior Credit Agreement
    which were used to pay the $4.2 million in fees and expenses incurred as a
    result of the Offering.
(8) The ratio of total debt to EBITDA (as defined) is computed by dividing (i)
    EBITDA (as defined) for the twelve months ended September 1997 by (ii)
    total debt as of September 1997 as adjusted for the Offering.
(9) As adjusted to give effect to the Offering and the payment of $4.2 million
    in fees and expenses in connection therewith, using proceeds from the
    Company's revolving credit facility under the Senior Credit Agreement.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion and analysis should be read in conjunction with
"Selected Consolidated Financial Data" and the Consolidated Financial
Statements of the Company and notes thereto included elsewhere in this
Offering Memorandum. This Offering Memorandum contains forward-looking
statements that involve risks and uncertainties, such as statements of the
Company's plans, objectives, expectations and intentions. The cautionary
statements made in this Offering Memorandum should be read as being applicable
to all related forward-looking statements wherever they appear in this
Offering Memorandum. See "Risk Factors."
 
OVERVIEW
 
  The Company currently manufactures and markets two classes of pharmaceutical
products, generic products and branded products. The Company's results of
operations depend on the Company's ability to develop and commercialize new
pharmaceutical products. Generally, following the expiration of patents and
any other market exclusivity periods for branded drugs, the first
pharmaceutical manufacturers successfully to market generic equivalents of
such drugs achieve higher revenues and gross profit from the sale of such
generic drugs than do others from the sale of generic equivalents subsequently
approved. As competing generic equivalents reach the market, the prices, sales
volumes and profit margins of the earliest generic versions often decline
significantly. For these reasons, the Company's ability to achieve growth in
revenues and profitability depends on its being among the first companies to
introduce new generic products. During the past five years, the Company has
introduced a significant number of generic products to the market at patent
expiration dates and in a number of cases prior to patent expiration of the
branded product by successful challenges to the patent under the Waxman-Hatch
Act.
 
  The Company's dependence on a limited number of products, the product cycles
of such products, and the timing of receipt of patent settlement revenues have
resulted in significant fluctuations in the Company's earnings. Continued
growth in the Company's revenues will depend on continued market demand for
its products, as well as the successful introduction and marketing of new
products.
 
  Net revenues from INFeD as a portion of total net revenues increased from
16% in 1994 to 20% in the nine months ended September 1997. Gross profit
margins on INFeD exceed gross profit margins on the Company's generic products
generally; accordingly, the gross profit from increased sales of INFeD have
offset the reduction in gross profit from generic products during the periods
presented.
 
  The following table sets forth the net revenues of the Company's generic and
branded businesses for each of the periods shown:

  From 1992 to 1994, the Company engaged in a series of corporate
reorganization transactions, including the separation of the Company from
Henry Schein, Inc., which is engaged in the direct marketing of health care
products and services to office-based health care practitioners. In connection
with these transactions, Bayer Corporation purchased from the Company's
stockholders 28.3% of the Company's outstanding shares for $312.4 million and
agreed with the Company to pursue future strategic alliances. Charges for
special compensation, restructuring and relocation incurred in connection with
the reorganization aggregated $7.4 million, $8.4 million and $33.6 million for
1992, 1993 and 1994, respectively.
 
  The Company acquired all the outstanding capital stock of Marsam (the
"Marsam Acquisition") in September 1995 for $245.0 million in cash, which
expanded the Company's ability to manufacture sterile penicillins and oral and
sterile cephalosporins.

 Nine Months Ended September 1997 Compared to Nine Months Ended September 1996
 
  Net revenues increased $1.6 million, or 0.5%, from $352.2 million in 1996 to
$353.8 million in 1997. In the branded business, sales increased $11.5
million, which offset a decline in sales of generic products of $9.9 million.
The increase in branded product sales reflected largely an increase in units
sold. The decline in generic revenues resulted from a $26.2 million decline in
the sales of core products and a $2.8 million decline in sales of
nortriptyline, offset by an $11.5 million increase in patent settlement
revenues received in the first quarter of 1997 and a $7.6 million increase in
sales of vecuronium bromide. The decrease in sales of core products reflected
the strategic decision in the second half of 1996 to discontinue certain low-
margin manufactured products and to reduce selling efforts on outsourced
products as well as competitive pressures on other core products, which was
offset by the impact of a $6.4 million increase in sales of new products.
 
  Gross profit decreased $2.2 million, or 1.9%, from $115.5 million in 1996 to
$113.3 million in 1997. The gross profit margin decreased from 32.8% in 1996
to 32.0% in 1997. This decline in gross profit was largely comprised of a
decline in gross profit on core products which was partially offset by
increased gross profit on INFeD, vecuronium bromide and new products. Gross
profit from patent settlements received in the first quarters of 1996 and 1997
contributed an additional $5.6 million, reduced by increased manufacturing
variances and other
 
                                      23

costs of $4.6 million. In the third quarter of 1997 compared to the third
quarter of 1996, the gross profit margin decreased from 32.6% to 29.7%,
reflecting a less favorable mix of products sold as well as competitive price
pressures.
 
  Selling, general and administrative expenses decreased $3.2 million, or
5.2%, from $61.1 million in 1996 to $58.0 million in 1997. Selling, general
and administrative expenses as a percent of net revenues decreased from 17.4%
in 1996 to 16.4% in 1997. The decrease in selling, general and administrative
expenses was due primarily to the effects of various cost reduction
initiatives, including a reduction in the retail field sales force. In the
third quarter of 1997, the Company experienced increased selling, general and
administrative expenses compared to earlier quarters of 1997 due primarily to
higher brand marketing expenses.
 
  Research and development expenses decreased $0.2 million, or 0.8%, from
$23.0 million in 1996 to $22.8 million in 1997. However, expenses in the third
quarter of 1997 increased compared to earlier 1997 quarters largely reflecting
costs associated with a development project nearing launch stage.
 
  Amortization of goodwill and other intangibles was unchanged compared to the
comparable period in 1996.
 
  As a result of the factors discussed above, operating income increased $1.2
million, or 5.1%, from $23.5 million in 1996 to $24.7 million in 1997.
 
  Interest expense, net increased $4.4 million, or 27.2%, from $16.1 million
in 1996 to $20.5 million in 1997 principally due to higher amortization of
deferred financing expenses of $2.5 million and increased interest costs of
$1.5 million resulting from refinancing of senior debt with higher cost
subordinated debt in December 1996.
 
  Other expense (income), net changed by $6.3 million from an expense of $1.7
million in 1996 to income of $4.5 million in 1997. Gains on the sale of
marketable securities of $9.9 million, primarily in the third quarter of 1997,
offset increased equity losses from the Company's investment in international
joint ventures of $1.0 million and other expenses.
 
  The Company's effective tax rate is higher than the statutory rate due to
the effect of significant non-deductible expenses. The effective tax rate
decreased from 62.5% in 1996 to 57.8% in 1997, primarily as a result of higher
income offsetting fixed non-deductible expenses.
 
 1996 Compared to 1995
 
  Net revenues increased $84.4 million, or 21.6%, from $391.9 million in 1995
to $476.3 million in 1996. In the generic business, net revenues increased
$63.5 million, and in the branded business, net revenues increased $21.0
million, driven by increased unit sales of INFeD. Increased revenues of
generic products consisted of $34.2 million in sales generated by vecuronium
bromide, a new product launched in March 1996, an $8.5 million increase in
patent settlement revenues and a $30.8 million increase in sales of the
Company's core products, offset in part by a decline in nortriptyline sales of
$10.0 million. The sales of core products increased primarily from the Marsam
Acquisition, which increased core product sales by $31.4 million, and from
$7.6 million in sales of new products, offset by an $8.2 million decrease in
sales of the Company's other core products, due primarily to price decreases.
 
  The Company's gross profit increased $14.3 million, or 10.1%, from $141.3
million in 1995 to $155.6 million in 1996. The gross profit margin fell from
36.1% in 1995 to 32.7% in 1996. An increase in gross profit of $31.2 million
was attributable to the Company's branded business, vecuronium bromide and
patent settlement revenues, which was partially offset by a $12.6 million
increase in manufacturing and regulatory costs.
 
  Selling, general and administrative expenses increased $11.1 million, or
15.2%, from $73.3 million in 1995 to $84.4 million in 1996. Selling, general
and administrative expenses decreased as a percentage of net revenues from
18.7% in 1995 to 17.7% in 1996. Selling, general and administrative expenses
increased due primarily to increased sales volume, the full year impact of the
Marsam Acquisition of $2.6 million and an increase in promotional activities
in support of new product launches.
 
                                      24
<PAGE>
 
  Research and development expenses decreased $1.3 million, or 4.6%, from
$28.3 million in 1995 to $27.0 million in 1996. Acquired in-process Marsam
research and development charges of $30.0 million were fully reflected in
1995.
 
  Amortization of goodwill and other intangibles increased $6.8 million from
$3.4 million in 1995 to $10.2 million in 1996, giving effect to the full year
impact of the Marsam Acquisition.
 
  As a result of the factors discussed above, operating income increased $27.7
million from $6.3 million in 1995 to $34.0 million in 1996.
 
  Interest expense, net increased $13.3 million from $10.0 million in 1995 to
$23.3 million in 1996. The increase was due primarily to the increase in
average debt associated with the debt financing for the Marsam Acquisition and
higher interest rates.
 
  Other expense (income), net increased by $3.4 million from $0.8 million in
1995 to $4.2 million in 1996. Equity losses from the Company's investment in
international joint ventures accounted for $3.0 million of the increase.
 
  The Company's effective tax rate is higher than the statutory rate due to
the effect of significant non-deductible expenses. The 1996 effective income
tax rate of 78.9% represented a decrease from the 1995 effective rate of
237.3% primarily due to the impact of certain non-recurring and non-deductible
expenses, which were largely comprised of the acquired in-process Marsam
research and development charge of $30.0 million.
 
 1995 Compared to 1994
 
  Net revenues increased $6.4 million, or 1.7%, from $385.4 million in 1994 to
$391.8 million in 1995. In the branded business, net revenues increased $6.1
million, and in the generic business, net revenues increased $0.3 million. The
increase in net revenues in the branded business resulted from an increased
number of units of INFeD sold. In the generic business, the changes consisted
of increases of $4.8 million in sales of new products, $5.0 million in new
patent settlement revenues and $14.0 million from the impact of the Marsam
Acquisition. These increases in the generic business were offset by a $13.6
million decrease in sales of nortriptyline and a $4.1 million decrease in
sales of the Company's other core products due primarily to price declines.
 
  The Company's gross profit decreased $6.7 million, or 4.5%, from $148.0
million in 1994 to $141.3 million in 1995. The gross profit margin decreased
from 38.4% in 1994 to 36.1% in 1995. The decrease was primarily a result of a
$12.8 million decrease attributable to lower selling prices of nortriptyline
and decreased gross profit on other core products due to competitive pricing
pressures. This was partially offset by a $4.0 million increase representing
the impact of the Marsam Acquisition, an increase in gross profit in the
Company's branded business and decreased manufacturing and regulatory costs.
 
  Selling, general and administrative expenses increased $1.9 million, or
2.6%, from $71.4 million in 1994 to $73.3 million in 1995. The increase in
selling, general and administrative expenses was due primarily to an increase
in sales volume, an increase in promotional activities in support of the
Company's branded business, new product launches and the Marsam Acquisition.
Selling, general and administrative expenses increased as a percentage of net
revenues from 18.5% in 1994 to 18.7% in 1995.
 
  Research and development expenses increased $9.1 million, or 47.8%, from
$19.2 million in 1994 to $28.3 million in 1995. Of the $9.1 million increase,
$2.1 million represented spending in connection with a worldwide technology
licensing and development agreement which the Company entered into during
September 1994, and the remaining increase in research and development
expenses was attributable to various new in-house development projects.
 
  Amortization of goodwill and other intangibles of $3.4 million and acquired
in-process Marsam research and development charges of $30.0 million in 1995
resulted from the Company's Marsam Acquisition in September 1995. See Note 3
to the Consolidated Financial Statements of the Company.
 
                                      25
<PAGE>
 
  The corporate reorganization and relocation were completed during 1994,
resulting in a $33.6 million charge. There were no restructuring or relocation
expenses incurred during 1995.
 
  As a result of the factors discussed above, operating income decreased $17.5
million from $23.9 million in 1994 to $6.4 million in 1995.
 
  Interest expense, net increased $8.5 million from $1.5 million in 1994 to
$10.0 million in 1995. The increase was due primarily to the increase in
average debt associated with the debt financing for the Marsam Acquisition
funded in September 1995.
 
  The Company's effective tax rate is higher than the statutory rate due to
the effect of significant non-deductible expenses. The 1995 effective income
tax rate of 237.3% increased from the 1994 effective income tax rate of 69.6%,
primarily due to the impact of certain non-recurring and non-deductible
expenses, which were largely comprised of the acquired in-process Marsam
research and development charge of $30.0 million. The 1994 effective income
tax rate also reflects the impact of non-deductible expenses, primarily
special compensation charges in connection with the corporate reorganization
completed during 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Historically, the Company has financed its business operations primarily
through a revolving credit facility and used long-term bank financing to fund
acquisitions. The Company plans to use the proceeds of the Offering as set
forth under "Use of Proceeds."
 
  Net cash provided by operating activities was $27.1 million and $10.8
million in the nine months ended September 1997 and in the year ended December
1996, respectively. The net cash provided by operating activities during 1997
was primarily attributable to net income, as adjusted for non-cash charges, of
$15.9 million and decreases in inventories and accounts receivable aggregating
$11.4 million. The net cash provided by operating activities during 1996 was
primarily attributable to net income, as adjusted for non-cash charges, of
$27.9 million and an increase in accounts payable and accrued expenses of
$11.9 million, offset by an increase in inventories and accounts receivable of
$31.0 million.
 
  Net cash provided by investing activities for the nine months ended
September 1997 and used in investing activities for the year ended December
1996 was $1.2 million and $20.0 million, respectively. Cash provided by
investing activities in 1997 resulted from the proceeds of sales of marketable
securities of $11.6 million, offset primarily by capital expenditures, net of
$9.0 million. The 1996 use of cash in investing activities was primarily due
to capital expenditures, net, purchase of product rights and licenses and
investments in international joint ventures of $17.4 million.
 
  Net cash used in financing activities for the nine months ended September
1997 of $30.1 million resulted from the net repayment of debt. Net cash
provided by financing activities for the year ended December 1996 of $3.6
million was primarily due to net proceeds of debt.
 
  In September 1995, the Company entered into a secured revolving credit and
term loan agreement (as amended, the "Senior Credit Agreement") with a group
of banks to provide funds for the Marsam Acquisition, the repayment of certain
debt, working capital and general corporate purposes. The Senior Credit
Agreement, which expires in December 2001, provided a term loan facility of
$250.0 million and a revolving credit facility of $100.0 million. In December
1996, the Company prepaid $100.0 million of the term loan portion of the
Senior Credit Agreement using the proceeds from a $100.0 million senior
subordinated loan (the "Senior Subordinated Loan") provided by Societe
Generale, New York branch, an affiliate of the Initial Purchaser and a lead-
manager of the Senior Credit Agreement. As a result of this payment and a
scheduled payment, the term loan facility was reduced to $145.0 million at
December 1996. In the first nine months of 1997, the Company made principal
payments of $15.0 million, thus reducing the term loan portion to $130.0
million at September 1997. Quarterly principal payments on the term loan
commence in September 1998 and end in the year 2001. Amortization
 
                                      26

amounts will total $13.7 million, $34.2 million, $41.0 million and $41.1
million in years 1998 through 2001, respectively. In addition to such
principal payments, the Company is required to make additional principal
payments in certain circumstances. Amounts outstanding under the revolving
credit facility were $41.0 million and $26.0 million as of December 1996 and
September 1997, respectively.
 
  Borrowings under the Senior Credit Agreement bear interest, which is payable
at least quarterly, at a rate equal to a floating alternate base rate (derived
from the greater of the prime rate of the Credit Agent (as defined herein),
the three-month secondary market rate for certificates of deposit plus 1.00%
and the Federal Funds rate plus 1/2 of 1.00%), plus a margin ranging from zero
to 1.50% or at a rate equal to LIBOR (as defined herein) plus a margin ranging
from 0.75% to 2.50%, depending on the type of borrowing and the Company's
performance against certain criteria. Outstanding borrowings under the Senior
Subordinated Loan through January 31, 1998 bear interest, payable quarterly,
at a rate equal to a floating alternate base rate (derived from the greater of
Societe Generale's prime rate, the three-month secondary market rate for
certificates of deposit plus 1.00% and the Federal Funds rate plus 1/2 of
1.00%) plus a margin of 3.00% or a rate equal to LIBOR plus a margin of 4.00%.
The original obligations under the Senior Subordinated Loan will be
effectively replaced by the Notes offered hereby. See "Description of Certain
Indebtedness."
 
  The Company believes that its existing credit facilities and cash expected
to be generated from operations are sufficient to finance its current level of
operations and currently contemplated capital expenditures.
 
  The Company has signed a non-binding letter dated October 7, 1997 with
Cheminor Drugs Limited and its subsidiaries ("Cheminor") and Dr. Reddy's
Laboratories Limited and its subsidiaries ("Reddy") outlining the parties'
intent to enter into a strategic alliance agreement. Cheminor will make
available to the Company its present and future dosage form generic products
on an exclusive basis in the United States and in certain countries, and the
Company will make available to Cheminor and Reddy its present and future
products on an exclusive basis for sale in India and certain other countries.
Cheminor and Reddy will make available to the Company bulk active
pharmaceutical ingredients. As part of the contemplated arrangement, the
Company would purchase 2.0 million publicly traded shares of Cheminor Drugs
Limited for $10.0 million, and under certain circumstances have the right and
the obligation to purchase an additional 1.0 million shares for $5.0 million.
Cheminor would have the right to make fair market value purchases of the
Company's Common Stock, once the shares are publicly traded; the purchase
price could be payable from profits otherwise due Cheminor from the alliance.
Each party would also be entitled to representation on the other company's
board of directors consistent with its equity interest. See "Certain
Transactions."
 
  In the event the Company makes any significant acquisitions, it may be
required to raise additional funds through the issuance of additional debt or
equity securities. There can be no assurance that such funds, if required,
would be available or, if available, would be on terms acceptable to the
Company.
 
  The Company has filed a registration statement covering an initial public
offering (the "Common Stock Offering") of its Common Stock. Consummation of
each of this Offering and the Common Stock Offering is not contingent upon
consummation of the other. There can be no assurance that the filing will
become effective or that any shares will be sold. If the Common Stock Offering
occurs, the Company intends to use a portion of the net proceeds from the
Common Stock Offering to repurchase or redeem a portion of the Notes offered
hereby.
 
QUARTERLY INFORMATION
 
  As a result of a variety of factors, including the introduction of new
products by the Company, the timing of receipt of patent settlement revenues
and changes in the degree of competition for the Company's products, the
Company's quarterly results of operations have fluctuated significantly and
are expected to fluctuate significantly in the future.

INFLATION
 
  Management does not believe inflation had a material adverse effect on the
financial statements for the periods presented.
 
EFFECT OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
  In June 1997, the Financial Accounting Standards Board issued two new
disclosure standards.
 
  Statement of Financial Accounting Standards No. 130 ("SFAS No. 130"),
Reporting Comprehensive Income, establishes standards for reporting and
display of comprehensive income, its components and accumulated balances.
Comprehensive income is defined to include all changes in equity except those
resulting from investments by owners and distributions to owners. Among other
disclosures, SFAS No. 130 requires that all items that are required to be
recognized under current accounting standards as components of comprehensive
income be reported in a financial statement that is displayed with the same
prominence as other financial statements.
 
  Statement of Financial Accounting Standards No. 131 ("SFAS No. 131"),
Disclosures about Segments of an Enterprise and Related Information, which
supersedes SFAS No. 14, Financial Reporting for Segments of a Business
Enterprise, establishes standards for the way that public enterprises report
information about operating segments in annual financial statements and
requires reporting of selected information about operating segments in interim
financial statements issued to the public. It also establishes standards for
disclosures regarding products and services, geographic areas and major
customers. SFAS No. 131 defines operating segments as components of an
enterprise about which separate financial information is available that is
evaluated regularly by the chief operating decision maker in deciding how to
allocate resources and in asserting performance.
 
                                      28
<PAGE>
 
  Both of these new standards are effective for financial statements for
periods beginning after December 15, 1997 and require comparative information
for earlier years to be restated. Results of operations and financial position
will be unaffected by implementation of these new standards. The Company has
not determined whether either of these two standards will have a material
impact on its financial statement disclosure.
 
RISK MANAGEMENT
 
  The Company is potentially subject to a concentration of credit risk with
respect to its trade receivables, the majority of which are due from
wholesalers, drug store chains and distributors. The Company performs ongoing
credit evaluations of its customers and generally does not require collateral.
The Company maintains sufficient allowances and insurance to cover potential
or anticipated losses for uncollectible accounts.
 
  The Company considers its investment in international subsidiaries and joint
ventures to be both long-term and strategic. As a result, the Company does not
hedge the long-term translation exposure to its balance sheet. Foreign
currency translations to date have not been material.
 
YEAR 2000 COMPLIANCE
 
  The Company is modifying its computer systems to be Year 2000 compliant. The
Company does not expect that the cost of modifying such systems will be
material. The Company believes it will achieve Year 2000 compliance in advance
of the year 2000 and does not anticipate any material disruption in its
operations as the result of any failure by the Company to be in compliance.
The Company does not have any information concerning the Year 2000 compliance
status of its suppliers and customers.

GENERAL
 
  Schein Pharmaceutical is one of the leading generic pharmaceutical companies
in the United States. The Company develops, manufactures and markets one of
the broadest generic product lines in the pharmaceutical industry through the
integration of its product development expertise, diverse, high-volume
production capacity and direct sales and marketing forces. The Schein product
line includes both solid dosage and sterile dosage generic products, and the
Company is also developing a line of specialty branded pharmaceuticals. The
Company's primary branded product, INFeD, is the leading injectable iron
product in the United States. The Company has a substantial pipeline of
products under development, including 24 ANDAs filed with FDA. The Company
supplements its internal product development, manufacturing and marketing
capabilities through strategic collaborations. Schein generated net revenues
of $478.0 million and EBITDA (as defined) of $55.8 million during the 12
months ended September 1997.
 
  The Company believes it manufactures and markets the broadest product line
of any U.S. pharmaceutical company in terms of number and types of products.
The Company manufactures and markets approximately 160 chemical entities
formulated in approximately 350 different dosages under approximately 200
ANDAs approved by FDA. Schein is currently the sole manufacturing source for
47 generic pharmaceutical products, of which 45 are sterile dosage products.
The Company's solid dosage products include both immediate-release and
extended-release capsules and tablets; sterile dosage products include
solutions, suspensions, powders and lyophilized (freeze-dried) products
primarily for administration as injections, ophthalmics and otics. The
manufacture of sterile dosage products is significantly more complex than the
manufacture of solid dosage products, which limits competition in this product
area. The Company currently manufactures approximately four billion solid
dosage tablets and capsules and 75 million sterile dosage vials and ampules
annually. Solid dosage generic products and sterile dosage generic products
each accounted for approximately 40% of the Company's net revenues in the 12
months ended September 1997.
 
  Since introducing INFeD in 1992, the Company has been developing a portfolio
of branded products, primarily in select therapeutic markets, such as iron
management for the nephrology, oncology and hematology markets. INFeD is used
in the treatment of certain types of anemia, particularly in dialysis
patients, and accounted for approximately 20% of the Company's net revenues in
the nine months ended September 1997. The Company markets INFeD through a 20-
person dedicated sales and marketing force, as well as through co-marketing
collaborations with Bayer Corporation in the nephrology market and MGI in the
oncology market.
 
  The Company believes its 120-person direct sales and marketing force is the
largest in the U.S. generic pharmaceutical industry. Through its customized
marketing programs, the Company markets its products to approximately 60,000
customers representing all major customer channels, including pharmaceutical
wholesalers, chain and independent drug retailers, hospitals, managed care
organizations, other group purchasing organizations and physicians.
 
  Schein's objective is to become the leading generic pharmaceutical company
in the approximately $10 billion generic pharmaceutical industry in the United
States. The Company's growth strategy is to: (i) leverage its diverse
pharmaceutical formulation and manufacturing capabilities to extend the
breadth of its generic product line; (ii) pursue strategic collaborations to
supplement product development and manufacturing resources; (iii) focus its
product development on complex and other generic drugs that require
specialized development or manufacturing technology and are therefore expected
to encounter limited competition; (iv) develop and market branded drugs for
select therapeutic categories; and (v) expand market penetration through
direct sales and innovative marketing programs.
 
  The Company's commitment to product development has resulted in 23 ANDA
approvals during the past three years and its current pipeline of 24 pending
ANDAs and over 60 additional products under development. During the past three
fiscal years, the Company, directly and through its strategic collaborations,
has expended
 
                                      30
<PAGE>
 
approximately $74.0 million on product pipeline development activities, which
the Company believes is among the highest product development expenditure
levels for any independent generic drug company. The Company pursues product
development through its 140-person product development staff and various
collaborations and licensing arrangements with other pharmaceutical and drug
delivery technology companies. The Company's product development efforts focus
on: (i) major branded drugs coming off patent; (ii) drugs for which patent
protection has lapsed and for which there are few or no generic producers;
(iii) drugs whose patents may be susceptible to challenge; (iv) proprietary
and branded products focused in select therapeutic areas; and (v) generic
products that require specialized development, formulation, drug delivery or
manufacturing technology.
 
  The Company supplements its internal product development, manufacturing and
marketing capabilities from external sources. During 1994, Schein entered into
a strategic alliance with Bayer Corporation, through which Bayer Corporation
became a 28.3% stockholder of Schein, and Bayer Corporation currently
participates with Schein in several collaborations. In 1995, the Company
acquired Marsam, expanding the Company's ability to develop and manufacture
sterile penicillins and oral and sterile cephalosporins. In addition, the
Company has entered into strategic collaborations involving product
development arrangements with companies such as Ethical and Elan; raw material
supply arrangements with companies such as Johnson Matthey and Abbott; and
sales and marketing arrangements with Bayer and other companies such as
Elensys and MGI.
 
INDUSTRY OVERVIEW
 
  In the U.S., pharmaceutical products are marketed as either branded or
generic. Branded products are marketed under brand names and through programs
designed to attract physician and consumer loyalty. Branded drugs generally
are covered by patents at the time of their market introduction, thereby
resulting in periods of market exclusivity for the patent holders. Following
the expiration of these patents, marketing of branded drugs often continues,
particularly in cases where there is significant physician or consumer
loyalty.
 
  Generic pharmaceuticals (also known as "multi-source" or "off-patent"
pharmaceuticals) are the chemical and therapeutic equivalents of branded
drugs. Under the Waxman-Hatch Act, generic drugs generally may be sold in the
United States following (i) FDA approval of an ANDA that includes evidence
that the generic drug is bioequivalent to its branded counterpart and (ii) the
expiration, invalidation or circumvention of any patents on the corresponding
branded drug and the expiration of any other market exclusivity periods
applicable to the branded drug.
 
  Since the adoption of the Waxman-Hatch Act, generic pharmaceuticals have
become an increasingly important segment of the U.S. pharmaceutical market,
particularly when measured in terms of the increasing rate at which doctors'
prescriptions have allowed generic drugs to be substituted for branded drugs.
In 1996, prescriptions dispensed in the United States for generic drugs
reached 40% of the total drug prescriptions dispensed. In terms of dollar
sales, however, generic drugs have accounted for a much lower percentage of
the total U.S. pharmaceutical market. In 1996, sales of generic drugs
accounted for approximately $10 billion out of a total U.S. prescription
pharmaceutical market of approximately $83 billion.
 
  The lower percentage of total dollar sales attributable to generic
pharmaceuticals compared to the growth in the number of generic pharmaceutical
prescriptions dispensed reflects the pricing dynamics for generic
pharmaceuticals. As the number of commercially available generic competitors
of a branded drug increases, their selling prices and gross margins decline
substantially. Generic drugs are generally sold at a 20% to 80% discount from
their branded counterparts. Intense price competition in the generic drug
industry requires companies to introduce new generic drug products regularly
in order to maintain and increase revenues.
 
  Growth of the generic drug industry has been driven primarily by the dollar
volume of branded drugs that have lost patent protection and the rising rate
at which generic drugs have been substituted for branded drugs. Industry
sources estimate that, during the next five years, branded drugs with 1996
U.S. sales of more than $13 billion will lose patent protection. The rising
rate of generic substitution has resulted in large part from increasing
pressure within the U.S. health care industry to contain costs. Due to the
lower cost of generic drugs compared
 
                                      31
<PAGE>
 
to their branded counterparts, third party payors, such as insurance
companies, company health plans, health maintenance organizations, managed
care organizations, pharmacy benefit managers, group purchasing organizations,
government-based programs and others, have adopted policies that encourage or
mandate generic substitution. In addition, physicians, pharmacists and
consumers are becoming increasingly comfortable with the quality and
therapeutic equivalence of generic drugs.
 
  A significant portion of pharmaceuticals are distributed in the United
States through wholesale drug distributors and major retail drug store chains.
During the past several years, there has been a consolidation of these
distribution channels, resulting in a smaller number of wholesale distributors
and the emergence of fewer, larger regional and nationwide retail drug store
chains. In addition to forcing generic drug manufacturers to lower their
prices and/or provide volume discounts, these customers have also been seeking
to reduce the number of sources from which they purchase pharmaceutical
products.
 
  Participants in the generic drug market include independent generic drug
manufacturers such as the Company, generic drug subsidiaries of large branded
pharmaceutical companies and joint ventures and collaborations between branded
pharmaceutical companies and generic drug manufacturers. The participation of
branded pharmaceutical companies in the U.S. generic industry accelerated
during the first half of the 1990s as pricing pressure and generic
substitution grew. The extent to which the branded pharmaceutical companies
will continue to participate in the generic drug industry segment cannot be
predicted by the Company.
 
  The Company believes it is well positioned to capitalize on these industry
trends by leveraging its product development, manufacturing and marketing
capabilities to expand its market penetration.
 
STRATEGY
 
  The Company's objective is to become the leading generic pharmaceutical
company in the approximately $10 billion generic pharmaceutical industry in
the United States. The Company's strategy for achieving this objective
comprises the following five elements:
 
  Leverage Diverse Pharmaceutical Formulation and Manufacturing Capabilities
to Extend the Breadth of Its Generic Product Line. The Company believes it
manufactures and markets the broadest product line of any U.S. pharmaceutical
company. This product line includes both solid dosage and sterile dosage
products comprising approximately 160 chemical entities in approximately 350
dosage forms and strengths under approximately 200 approved ANDAs. Solid
dosage forms include both immediate-release and extended-release capsules and
tablets; sterile dosage forms include solutions, suspensions, powders and
lyophilized (freeze-dried) products primarily for administration as
injections, ophthalmics and otics. The Company believes its diverse high-
volume manufacturing capabilities enable it to participate in segments of the
generic drug industry where competition is limited. As the U.S. generic drug
market consolidates and major drug buyers increasingly purchase from fewer
suppliers, the Company believes its high volume and diverse drug formulation
and manufacturing capabilities will constitute an important competitive
advantage.
 
  Pursue Strategic Collaborations to Supplement Product Development and
Manufacturing Resources. Schein has formed product development and marketing
alliances with several bulk pharmaceutical producers, drug delivery technology
companies and other drug manufacturers to expand the breadth of its product
development capabilities. Included among these are collaborations with drug
delivery companies, Elan and Ethical, and several bulk pharmaceutical and
finished dosage form producers. The Company plans to utilize collaborative and
licensing arrangements with third parties to share product development risk
and gain access to sales and marketing rights, dosage forms, proprietary drug
delivery technologies, specialized formulation capabilities and active
pharmaceutical ingredients.
 
 
                                      32
<PAGE>
 
  Focus Product Development on Complex and Other Generic Drugs that Require
Specialized Development or Manufacturing Technology and Encounter Limited
Competition. The Company targets generic drugs for which it believes it can
achieve relatively high margins by being the first or among the first generic
manufacturers to launch the product. The Company is currently the sole generic
source for 47 products, and the Company is developing several "complex
generic" drugs that are difficult to duplicate due to formulation and/or
manufacturing complexities and other generic drugs for which raw materials are
in limited supply. In addition, the Company closely analyzes pharmaceutical
patents and initiates patent challenges where appropriate opportunities exist.
Products currently being considered for development include several that could
lead to patent challenges. The Company has generated significant revenues and
profits from generic products that have been the subject of successful patent
challenges initiated by the Company.
 
  Develop and Market Branded Drugs for Select Therapeutic
Categories. Leveraging its broad pharmaceutical formulation, development and
manufacturing capabilities, the Company targets branded drug development and
marketing opportunities in select therapeutic categories with limited
competition. The Company's branded drug development and marketing efforts
currently focus on injectable products used in the management of iron-related
disorders. The Company's first branded product, INFeD, is the leading
injectable iron product in the U.S. Schein's near-term development plan is to
expand the Company's iron management expertise into the oncology, hematology
and gastroenterology markets, and the Company expects that an NDA for its next
generation injectable iron product will be filed with FDA in the first half of
1998. The Company also is pursuing opportunities to broaden its branded
pharmaceutical product line by: (i) formulating and developing, either
internally or through development collaborations, unique products that may be
patented; (ii) acquiring products developed by other drug companies; and (iii)
acquiring formulation technologies for developing new dosage forms of existing
drugs.
 
  Expand Market Penetration through Direct Sales and Innovative Marketing
Programs. The Company believes its 120-person direct sales and marketing force
is the largest in the U.S. generic pharmaceutical industry. This sales and
marketing force includes 90 field representatives, 20 telemarketing
representatives and 10 marketing personnel and covers all major customer
groups, including chain and independent drug retailers, managed care
organizations, pharmaceutical wholesalers, hospitals and group purchasing
organizations. The Company has developed market share initiatives with
selected leading chain and wholesale customers and developed and implemented
customized marketing programs to meet specific customer needs, including
customer inventory management, patient-focused education and compliance
programs. With respect to its branded product business, the Company has a team
of approximately 20 sales representatives dedicated to marketing INFeD. This
sales and marketing force is complemented by marketing collaborations with
Bayer in the nephrology market and MGI in the oncology market.
 
PRODUCTS
 
  The Company believes it manufactures and markets the broadest number of
products of any U.S. pharmaceutical company in terms of number and types of
products. The Company's product line includes both solid dosage and sterile
dosage generic products; the Company is also developing a line of specialty
branded pharmaceuticals. The Company manufactures and markets approximately
160 chemical entities in approximately 350 dosage forms and strengths under
approximately 200 approved ANDAs. Schein is currently the sole generic source
for 47 pharmaceutical products.

 Generic Products
 
  The Company's generic business consists of the manufacturing and marketing
of sterile and solid dosage products and the marketing of certain additional
purchased products.
 
  The Company's sterile dosage product portfolio is comprised of approximately
110 products and accounted for approximately 37% of the Company's total net
revenues in the nine months ended September 1997. This portfolio includes
vecuronium bromide, an anesthetic product that is currently the Company's
largest selling generic product. The Company is manufacturing and marketing
vecuronium bromide prior to expiration of the patent covering this product
pursuant to a licensing arrangement. None of the Company's other sterile
dosage products accounted for more than 6% of net revenues in the nine months
ended September 1997. Included in the sterile dosage product portfolio are 45
products for which the Company is currently the sole generic source, one of
which is vecuronium bromide.
 
  The Company's solid dosage product portfolio is comprised of approximately
50 products and accounted for approximately 30% of the Company's total net
revenues in the nine months ended September 1997. None of the Company's solid
dosage products accounted for more than 6% of net revenues in the nine months
ended September 1997. The Company's solid dosage portfolio includes two
products for which the Company is currently the sole generic source.
 
  The Company supplements its manufactured product line with purchased
products. The margins received by the Company on these products, however, are
generally lower than the margins received by the Company on products that it
manufactures. In addition, the Company believes its customers are increasingly
seeking to purchase products directly from manufacturers. The percentage of
the Company's total net revenues of generic products manufactured by others
has declined from approximately 18% in 1995 to 13% for the nine months ended
September 1997.
 
 Branded Products
 
  Until 1992, the Company's focus was on generic pharmaceutical products. In
1992, the Company introduced INFeD, its primary branded product, and currently
has other branded products under development. The Company focuses on products
used in the management of iron-related disorders. Currently, INFeD, an
injectable iron dextran used in the treatment of severe anemia or iron
deficiency, accounts for approximately 20% of the Company's net revenues.
INFeD is most commonly used in the U.S. to treat iron deficiency anemia in
patients with end-stage renal disease (ESRD) who are receiving therapy with
recombinant human erythropoietin (EPO). In addition to the dialysis market,
the high incidence of iron deficiency anemia related to other medical
conditions presents further opportunities for the Company to leverage its
existing INFeD sales and marketing capabilities.
 
  The Company is seeking to expand its branded pharmaceutical business through
internal development and collaborative arrangements with other companies, with
a particular view to leveraging its expertise in iron

 Iron Management Market
 
  In recent years, there has been increasing focus on improving the quality of
life of patients undergoing chronic disease therapy through, among other
means, iron management. The oxygen carrying component of red blood cells,
hemoglobin, requires iron to function efficiently. In some cases, iron
management requires the treatment of iron deficiency and, in other cases, the
treatment of iron excess. The Company is currently marketing and developing
prescription products for the treatment of anemia in the dialysis and oncology
markets, and seeks to market INFeD for the gastroenterology and bloodless
medicine markets.
 
  Dialysis Market. The dialysis market is currently the largest market for
injectable iron and iron replacement products. Orally administered iron has
historically been, and continues to be, the first form of treatment used by
doctors to treat anemia in dialysis patients. Research has shown, however,
that orally administered iron inadequately treats iron deficiency in dialysis
patients and that injectable iron is more rapidly and directly absorbed in the
body. The National Kidney Foundation's Dialysis Outcome Quality Improvement
(DOQI) guidelines encourage more consistent use of injectable iron to
supplement the use of oral iron in dialysis patients. Approximately 60% to 65%
of dialysis patients are given injectable iron at least once a year. EPO
therapy is currently used to treat approximately 92% of all dialysis patients.
EPO allows patients to generate their own red blood cells, thus greatly
reducing the need for blood transfusions. One of the effects of EPO treatment,
however, is rapid mobilization of iron reserves and depletion of iron stores.
The Company believes that certain studies indicate that INFeD can be used
together with EPO to overcome this iron depletion effect. Accordingly, the use
of EPO therapy has created a need for iron management techniques.
 
  Oncology Market. In the oncology market, which includes patients with cancer
and cancer-related illnesses, anemia is a significant side effect of the
disease and the drugs used in treatment of the disease. Fatigue associated
with anemia is not widely recognized or treated as part of cancer treatment
regimens. Although there is a small base of injectable iron users in this
area, the Company believes there is potential for market expansion.
 
  Hematology and Gastroenterology. INFeD may also have applications in the
area of bloodless medicine. Bloodless medicine is surgery without the use of
blood infusions or transfusions; instead, plasma is supplemented with iron
that is administered to the patient before surgery to build up red blood cells
or after surgery to more rapidly replace red blood cells lost during surgery.
In the gastroenterology market, of the over one million patients with
inflammatory bowel disease, 30% to 70% experience anemia, mostly due to iron
deficiency.
 
  INFeD. INFeD (iron dextran injection, USP 50 mg/mL) is a liquid complex of
ferric hydroxide and dextran that is used in the treatment of patients with
documented iron deficiency in whom oral administration is unsatisfactory or
impossible. INFeD's product label includes the following warning: "Warning:
The parenteral use of complexes of iron and carbohydrates has resulted in
anaphylactic-type reactions. Deaths associated with such administration have
been reported. Therefore, INFeD (iron dextran injection, USP 50 mg/mL) should
be used only in those patients in whom the indications have been clearly
established and laboratory investigations confirm an iron-deficient state not
amenable to oral iron therapy."
 
  Currently, iron dextran is the only injectable iron formulation in the U.S.
market. The Company introduced its injectable iron product, INFeD, in May
1992. INFeD currently has approximately 85% of the injectable iron market, and
iron dextran products are marketed by one other company in the U.S. Net sales
of INFeD in 1996
 
                                      35

and the nine months ended September 1997 were $88.0 million and $72.1 million,
respectively, and accounted for 19% and 20%, respectively, of the Company's
net revenues. Growth in sales of INFeD has been driven by the expanding use of
EPO and the growing recognition of patient outcomes and quality of life issues
associated with iron deficiency anemia in dialysis patients. For patients
being treated with EPO, injectable iron therapy has become adjunctive therapy
rather than supportive therapy, as studies have shown that anemic patients may
become resistant to EPO and that injectable iron can help to maintain EPO
responsiveness and optimize its effectiveness. The Company believes that the
dialysis market should continue to expand with the expected increase in the
ESRD population, as well as the expanding use of hemodialysis in the treatment
of ESRD patients.
 
  Ferrlecit. Ferrlecit (sodium ferric gluconate complex in sucrose injection)
is intended to be the Company's next generation injectable iron product.
Ferrlecit is administered parenterally to treat hemodialysis patients with
iron deficiency anemia.
 
  Ferrlecit was developed by the Nattermann Company, of Cologne (now Rhone-
Poulenc Rorer GMBH) and is widely used in Europe. In 1996, pursuant to an
exclusive trademark and distribution agreement with Makoff R&D Laboratories
("R&DL"), a specialty renal pharmaceutical company, the Company acquired the
exclusive right to market and distribute Ferrlecit in the U.S. and several
other countries for a period of ten years after market authorization has been
granted by FDA. R&DL has completed Phases I, II and III clinical trials and
expects to file an NDA in the first half of 1998. See "--Government
Regulations--NDA Process."
 
 Other Products
 
  Unipine XL. In the U.K., the Company is currently manufacturing and
marketing Unipine XL, a once- a-day version of nifedipine used in the
treatment of hypertension, pursuant to a license obtained from Ethical. The
Company is also preparing for Unipine XL's launch in Israel, South Africa, the
Caribbean and selected markets in Latin America and Asia.
 
PRODUCT DEVELOPMENT
 
  The Company seeks to expand its product portfolio through continuing
investment in research and development. As a result of its approximately $74.0
million investment in product development over the past three fiscal years,
the Company has 24 ANDAs pending with FDA and over 60 products under
development internally and with third parties. The Company believes that this
investment in development activities should accelerate its ANDA filings and
launches in the next several years. The Company's product development
activities are conducted by 140 research and development professionals and
supported by others with expertise in manufacturing, technology, legal,
regulatory and intellectual property issues.
 
  The Company's generic product development efforts focus on: (i) major
branded drugs coming off patent; (ii) drugs for which patent protection has
lapsed and for which there are few or no generic producers; (iii) drugs whose
patents may be susceptible to challenge; (iv) proprietary and branded products
in select therapeutic areas; and (v) generic products that require specialized
development, formulation, drug delivery or manufacturing technology. In
furtherance of its strategy to be among the first to market generic versions
of brand drugs, the Company uses its scientific, pharmacologic, manufacturing
and legal expertise to identify brand products covered by patents that are
susceptible to challenge or circumvention. When the Company decides to pursue
development of a generic version of a brand product so identified, it seeks a
source for the drug's active pharmaceutical ingredient, develops a formulation
for the drug, conducts bioequivalence studies on its formulation and prepares
an ANDA filing. The ANDA filing must include a certification from the Company
that the patent on the brand product is invalid or not infringed, and the
patent holder must be provided with notice of the filing and basis for the
certification. If the patent holder commences litigation within 45 days of the
notice, FDA may not approve the ANDA for a period of 30 months, unless the
case is resolved earlier in court or by settlement. A successful patent
challenge may result in a court determination that the patent on the brand
product is invalid, not infringed or unenforceable. Alternatively, a
settlement with the patent holder may include a license to the Company to sell
the generic version of the brand product prior to the expiration of the patent
covering the product.
 
 
                                      36
<PAGE>
 
  In its branded product business, the Company intends to develop products for
the management of iron-related disorders and select other businesses, as well
as promote the use of its primary branded product, INFeD, beyond the dialysis
market to other therapeutic areas, such as oncology and gastroenterology.
 
STRATEGIC COLLABORATIONS
 
  To expand its product portfolio and improve its profitability, the Company
will continue to pursue strategic collaborations to access additional dosage
forms, proprietary drug delivery technology, specialized formulation
capabilities and sources of bulk active materials. The Company has product
development arrangements with companies such as Ethical and Elan;
collaborative arrangements for direct access to raw materials with, among
others, Johnson Matthey and Abbott; and sales and marketing arrangements with
companies such as Bayer Corporation, Elensys and MGI. The Company has recently
entered into a non-binding letter of intent regarding Cheminor and Reddy. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."
 
MANUFACTURING AND DISTRIBUTION
 
  The Company operates five manufacturing facilities and two distribution
centers. The following table presents the facilities owned or leased by the
Company and indicates the location and type of each of these facilities:

 Manufacturing Facilities
 
  The Company's aggregate manufacturing capacity is among the largest of any
generic pharmaceutical company in the United States. The diversity and
capacity of these facilities are important elements of the Company's strategy
to expand the range of its existing product line and provide several
significant benefits, including (i) the ability to satisfy the growing
preference among many of the Company's customers for buying pharmaceuticals
directly from manufacturers and from fewer sources, (ii) added flexibility in
raw materials sourcing and manufacturing cost control, and (iii) economies of
scale with respect to manufacturing infrastructure functions common to solid
dosage manufacturing and/or sterile dosage manufacturing, such as water
distillation, air purification, drug formulation systems, filling and
packaging lines, and quality control and regulatory compliance. See "--
Strategy" and "--Government Regulations."
 
  The Company has made a substantial investment in plant and equipment and
believes that it is unique in its capacity to produce a broad line of both
sterile dosage products and solid dosage products. The Company manufactures a
variety of product forms and types, including immediate-release and extended-
release solid dosage products and sterile anti-infectives, injectables,
penicillins, cephalosporins, ophthalmics and otics. The
 
                                      37
<PAGE>
 
Company currently produces approximately four billion tablets and capsules and
75 million vials and ampules annually and has the capacity to increase
production to six billion tablets and capsules and 100 million vials and
ampules annually. This range of manufacturing capabilities allows the Company
to participate in segments of the generic industry where competition is
limited. Further, the Company's high-volume production enables it to obtain
favorable access to raw materials, which typically represent a substantial
portion of the cost of producing drug products. See "Risk Factors--Dependence
on Regulatory Approval and Compliance."
 
  The Company is one of only two U.S. generic manufacturers with dedicated
sterile filling facilities for cephalosporin and penicillin antibiotics, which
target the high volume institutional injectable market. In addition, the
Company's ophthalmic and otic drug manufacturing facilities target higher
margin specialty markets.
 
  In accordance with FDA requirements for manufacturers of finished
pharmaceutical products, the Company has developed strict quality control
procedures to ensure the quality and safety of its products. The Company
employs sanitary handling procedures, customized systems for monitoring and
regulating environmental conditions and back-up systems for many of the
critical steps in the production processes. The Company performs sample
testing of raw materials and packaging supplies used in manufacturing its
products and conducts on-site audits of raw material suppliers. In its
manufacturing process, the Company maintains strict quality control procedures
and believes it is in material compliance with FDA's cGMP standards. The
Company has approximately 380 employees dedicated to quality control and
quality assurance. Because developing and obtaining approval of new generic
products requires a large investment and several years of lead time, the
Company believes that companies like itself that have modern, versatile
manufacturing facilities will have a competitive advantage in responding to
market opportunities. See "Risk Factors--Dependence on Regulatory Approval and
Compliance," "Risk Factors--Pending Regulatory Matters" and "--Government
Regulations."
 
  The Company does not manufacture the active pharmaceutical ingredients used
in the preparation of its products. Instead, the Company purchases these
active pharmaceutical ingredients from international and domestic sources. FDA
requires pharmaceutical manufacturers to identify in their drug applications
the supplier(s) of all the raw materials for its products. If raw materials
for a particular product become unavailable from an approved supplier
specified in a drug application, any delay in the required FDA approval of a
substitute supplier could interrupt manufacture of the product, which could
materially and adversely affect the Company's profit margins and market share
for the product. To the extent practicable, the Company attempts to identify
more than one supplier in each drug application. However, in the case of
certain products (including certain products that contribute (or may
contribute) significantly to its sales and net income), the Company has
submitted drug applications that identify only one supplier. The Company has a
program of identifying alternative suppliers where practicable and, in many
cases, filing supplemental applications with FDA for approval.
 
  The Company obtains a significant portion of its raw materials from
international suppliers. Arrangements with international raw material
suppliers are subject, among other things, to FDA, customs and other
government clearances, various duties and regulation by the country of origin.
The Company has a number of collaborative arrangements for exclusive access to
some difficult to source products.
 
SALES AND MARKETING
 
  The Company believes that it has one of the largest direct sales and
marketing forces in the generic drug industry, with approximately 90 field
representatives, 20 telemarketing representatives and 10 marketing personnel.
This team is focused on enhancing pharmacist and payor knowledge of the Schein
product line and providing a differentiated level of customer service and
support. The sales and marketing force promotes Schein's newly approved
products and supports customers with innovative, value added services in
inventory management and patient education.
 
  The Company's broad customer base, which purchases from wholesalers and
directly from the Company, includes: retail customers, including chain drug
stores, mass merchandisers, food stores and independent drug stores; wholesale
distributors; managed care providers, including group purchasing
organizations, HMOs and
 
                                      38
<PAGE>
 
mail order companies; alternative site customers, such as long term care
companies, home infusion companies and surgery centers; and medical/surgical
suppliers.
 
  Most pharmaceuticals today are sold through national and regional
wholesalers, who command approximately 80% of the U.S. drug distribution
market. While pharmaceutical products are typically distributed via these
wholesalers, pharmaceutical companies often directly enter into contracts with
the retail chains, managed care and institutional customers covering the
actual acquisition price. Under these arrangements, wholesalers often serve as
depots for substantially all of a customer's product needs, allowing it to
maintain minimal inventories and receive overnight deliveries of several
manufacturers' products from a single source. Currently, approximately 64% of
the Company's revenues are sold through wholesalers, with approximately 82% of
these revenues subject to direct contracts between the Company and its
customers. In general, it is the Company's strategy to seek to enter into
purchase contracts with retail, managed care and institutional customers.
Sales to Bergen Brunswig Corporation, Cardinal Health, Inc. and McKesson Drug
Company accounted for 17%, 16% and 11%, respectively, of the Company's total
net revenues for the nine months ended September 1997 and accounted for 16%,
15% and 11%, respectively, of the Company's total net revenues in fiscal 1996.
 
  The vast majority of the Company's products are sold under the "Schein
Pharmaceutical," "Marsam Pharmaceuticals" and "Steris Laboratories" labels. In
addition, the Company sells a limited number of products to distributors under
private labels.
 
  The Company directs its sales and marketing activities through programs
specific to its generic product and branded product businesses.
 
 Generic Products
 
  The Company has one of the largest generic sales and marketing organizations
in the U.S. generic pharmaceutical industry, with a sales and marketing
organization of 120 people serving the retail, institutional, alternative
site, managed care and other generic drug purchasing markets, including a 20-
person telemarketing sales force and 10 marketing personnel supporting the 90-
person field sales organization. The Company's large sales and marketing force
permits effective coverage of all purchasers of generic products. The sales
and marketing force promotes newly approved products, encourages substitution
of the Company's generic products for branded products and supports the
customer with value added services in inventory management and patient
education.
 
  The Company has developed market share initiatives with selected leading
chain and wholesale customers and has implemented customized marketing
programs to meet specific customer needs, including the following:
 
  .  The Company has developed and implemented a unique vendor managed
     inventory program, Schein Pharmaceutical Managed Auto Replenishment
     Technology ("S.M.A.R.T.(TM)"), which monitors customers' inventory levels
     daily to ensure adequate stocking levels, minimize the occurrence of back
     orders and returned goods and enhance inventory turnover for such key
     customers.
 
  .  The Company uses state-of-the-art electronic data interchange ("EDI")
     systems, which enable it to efficiently exchange data with its key
     wholesale and retail customers for a variety of transactions.
 
  .  The Company offers a patient compliance program through which consumers
     receive prescription refill reminders from their pharmacies.
 
  .  The Company has designed the Generic Acceptance and Intervention Network
     ("G.A.I.N.(TM)"), a patient-focused education program to promote the use
     of generic products for its customers.
 
 Branded Products
 
  The Company has a sales and marketing organization of 20 people dedicated to
marketing INFeD. The Company also has established a co-promotion arrangement
with Bayer Corporation under which 150 of Bayer's
 
                                      39
<PAGE>
 
specialty sales representatives devote a portion of their time in the United
States and Puerto Rico detailing INFeD to the nephrology market. In addition,
as part of its marketing effort in the oncology market, the Company entered
into a co-promotion arrangement with MGI in March 1997 for MGI's 21-person
sales force to support INFeD in the oncology market.
 
COMPETITION
 
  In the generic pharmaceutical business, the Company competes with a number
of companies, including independent generic manufacturers and larger
pharmaceutical companies, which sell the same generic equivalents of the
Company's products. Many companies, including large pharmaceutical firms with
financial and marketing resources and development capabilities substantially
greater than those of the Company, are engaged in developing, marketing and
selling products that compete with those offered by the Company. The selling
prices of the Company's products may decline as competition increases.
Further, other products now in use or under development by others may be more
effective than the Company's current or future products. The pharmaceutical
industry is characterized by intense competition and rapid product development
and technological change. The Company's pharmaceuticals could be rendered
obsolete or made uneconomical by the development of new pharmaceuticals to
treat the indications addressed by the Company's products, technological
advances affecting the cost of production, or marketing or pricing actions by
one or more of the Company's competitors. The Company's business, results of
operations and financial condition could be materially adversely affected by
any one or more of such developments. Competitors may also be able to complete
the regulatory process for certain products before the Company and, therefore,
may begin to market their products in advance of the Company's products. The
Company believes that competition among prescription pharmaceuticals and
generics will be based on, among other things, product efficacy, safety,
reliability, availability and price. The Company believes that various
competitive factors, including pressure from major wholesalers and delays in
generic drug approvals by FDA, led to price declines beginning in mid-1996 for
generic drugs, largely offsetting growth in unit sales.
 
  From time to time, the Company may compete for the in-license or acquisition
of certain branded products with other pharmaceutical companies pursuing a
similar strategy. The Company's branded product competes with generic
pharmaceuticals which claim to offer equivalent therapeutic benefits at a
lower cost. In some cases, third-party payors encourage the use of lower cost
generic products by paying or reimbursing a user or supplier of a branded
prescription product a lower purchase price than would be paid or reimbursed
for a generic product, making branded products less attractive, from a cost
perspective, to buyers. The aggressive pricing activities of the Company's
generic competitors and the payment and reimbursement policies of third-party
payors could have a material adverse effect on the Company's business, results
of operations and financial condition.
 
GOVERNMENT REGULATIONS
 
  The research, development and commercial activities relating to branded and
generic prescription pharmaceutical products are subject to extensive
regulation by U.S. and foreign governmental authorities. Certain
pharmaceutical products are subject to rigorous pre-clinical testing and
clinical trials and to other approval requirements by FDA in the United States
under the Federal Food, Drug and Cosmetic Act (the "FDCA") and the Public
Health Services Act and by comparable agencies in most foreign countries.
 
  The FDCA, the Public Health Services Act, the Controlled Substances Act and
other federal statutes and regulations govern or influence all aspects of the
Company's business. Noncompliance with applicable requirements can result in
fines and other judicially imposed sanctions, including product seizures,
injunctive actions and criminal prosecutions. In addition, administrative or
judicial actions can result in the recall of products and the total or partial
suspension of the manufacturing of products, as well as the refusal of the
government to approve pending applications or supplements to approved
applications. FDA also has the authority to withdraw approvals of drugs in
accordance with statutory due process procedures. See "Risk Factors--
Dependence on Regulatory Approval and Compliance" and "Risk Factors--Pending
Regulatory Matters."
 
 
                                      40
<PAGE>
 
  FDA approval is required before any dosage form of any new unapproved drug,
including a generic equivalent of a previously approved drug, can be marketed.
All applications for FDA approval must contain information relating to product
formulation, stability, manufacturing processes, packaging, labeling and
quality control. In addition, acts of foreign governments may affect the price
or availability of raw materials needed for the development or manufacture of
generic drugs.
 
 ANDA Process
 
  The Waxman-Hatch Act established abbreviated application procedures for
obtaining FDA approval for those drugs which are off-patent and whose non-
patent exclusivity under the Waxman-Hatch Act has expired and which are shown
to be bioequivalent to previously approved brand name drugs. Approval to
manufacture these drugs is obtained by filing an ANDA. An ANDA is a
comprehensive submission which must contain data and information pertaining to
the formulation, specifications and stability of the generic drug as well as
analytical methods and manufacturing process validation data and quality
control procedures. As a substitute for clinical studies, FDA requires data
indicating that the ANDA drug formulation is bioequivalent to a previously
approved NDA drug. In order to obtain an ANDA approval of a strength or dosage
form which differs from the referenced brand name drug, an applicant must file
and have granted an ANDA Suitability Petition. A product is not eligible for
ANDA approval if it is not bioequivalent to the referenced brand name drug or
if it is intended for a different use. However, such a product might be
approved under an NDA with supportive data from clinical trials.
 
  The advantage of the ANDA approval process is that an ANDA applicant
generally can rely upon bioequivalence data in lieu of conducting pre-clinical
testing and clinical trials to demonstrate that a product is safe and
effective for its intended use(s). The Company files ANDAs to obtain approval
to manufacture and market its generic products. No assurance can be given that
ANDAs or other abbreviated applications will be suitable or available for the
Company's products or that the Company's proposed products will receive FDA
approval on a timely basis, if at all. While the FDCA provides for a 180-day
review period, the Company believes the average length of time between initial
submission of an ANDA and receiving FDA approval is approximately two years.
 
  While the Waxman-Hatch Act established the ANDA, it has also fostered
pharmaceutical innovation through such incentives as market exclusivity and
patent restoration. The Waxman-Hatch Act provides two distinct market
exclusivity provisions which either preclude the submission or delay the
approval of a competitive drug application. A five-year marketing exclusivity
period is provided for new chemical compounds and a three-year marketing
exclusivity period is provided for applications containing new clinical
investigations essential to the approval of the application. The non-patent
market exclusivity provisions apply equally to patented and non-patented drug
products. Any entitlement to patent marketing exclusivity under the Waxman-
Hatch Act is based upon the term of the original patent plus any patent
extension granted under the Waxman-Hatch Act as compensation for reduction of
the effective life of a patent as a result of time spent by FDA in reviewing
the innovator's NDA. The patent and non-patent marketing exclusivity
provisions do not prevent the filing or the approval of an NDA. Additionally,
the Waxman-Hatch Act provides 180-day market exclusivity against effective
approval of another ANDA for the first ANDA applicant who (a) submits a
certificate challenging a listed patent as being invalid or not infringed and
(b) successfully defends in court any patent infringement action based on such
certification. The brand product segment of the pharmaceutical industry has
initiated legislative efforts to limit the impact of the Waxman-Hatch Act,
both on the federal and state levels. Recently, legislation has been
introduced designed to extend the patent protection on certain brand
pharmaceuticals and efforts have been made by the brand pharmaceutical
industry to introduce legislation to limit generic firms' ability to begin
research and development activities prior to patent expiration. In addition,
the brand product pharmaceutical companies have also initiated legislative
efforts in various states to limit the substitution of generic versions of
certain types of branded pharmaceuticals. The Company cannot predict whether
any such legislation will be enacted.
 
 
                                      41
<PAGE>
 
 NDA Process
 
  An NDA is a filing submitted to FDA to obtain approval for a drug not
eligible for an ANDA and must contain complete pre-clinical and clinical
safety and efficacy data or a right of reference to such data. Before dosing a
new drug in healthy human subjects or patients may begin, stringent government
requirements for pre-clinical data must be satisfied. The pre-clinical data,
typically obtained from studies in animal species, as well as from laboratory
studies, are submitted in an Investigational New Drug ("IND") application, or
its equivalent in countries outside the United States, where clinical trials
are to be conducted. The pre-clinical data must provide an adequate basis for
evaluating both the safety and the scientific rationale for the initiation of
clinical trials.
 
  Clinical trials are typically conducted in three sequential phases, although
the phases may overlap. In Phase I, which frequently begins with the initial
introduction of the compound into healthy human subjects prior to introduction
into patients, the product is tested for safety, adverse effects, dosage,
tolerance, absorption, metabolism, excretion and other elements of clinical
pharmacology. Phase II typically involves studies in a small sample of the
intended patient population to assess the efficacy of the compound for a
specific indication, to determine dose tolerance and the optional dose range
as well as to gather additional information relating to safety and potential
adverse effects. Phase III trials are undertaken to further evaluate clinical
safety and efficacy in an expanded patient population at typically dispersed
study sites, in order to determine the overall risk-benefit ratio of the
compound and to provide an adequate basis for product labeling. Each trial is
conducted in accordance with certain standards under protocols that detail the
objectives of the study, the parameters to be used to monitor safety and the
efficacy criteria to be evaluated. Each protocol must be submitted to FDA as
part of the IND.
 
  Data from pre-clinical testing and clinical trials may be submitted to FDA
as an NDA for marketing approval and to foreign health authorities as a
marketing authorization application. The process of completing clinical trials
for a new drug is likely to take several years and require the expenditure of
substantial resources. Preparing an NDA or marketing authorization application
involves considerable data collection, verification, analysis and expense, and
there can be no assurance that approval from FDA or any other health authority
will be granted on a timely basis, if at all. The approval process is affected
by a number of factors, primarily the risks and benefits demonstrated in
clinical trials as well as the severity of the disease and the availability of
alternative treatments. FDA or other health authorities may deny an NDA or
marketing authorization application if the regulatory criteria are not
satisfied, or such authorities may require additional testing or information.
 
  Even after initial FDA or other health authority approval has been obtained,
further studies, including Phase IV post-marketing studies, may be required to
provide, for example, additional data on safety, and will be required to gain
approval for the use of a product as a treatment for clinical indications
other than those for which the product was initially tested. Also, FDA or
other regulatory authorities require post-marketing reporting to monitor
serious and unanticipated adverse effects of the drug. Results of post-
marketing programs may limit or expand the further marketing of the products.
Further, if there are any modifications to the drug, including changes in
indication, manufacturing process or labeling or a change in manufacturing
facility, an application seeking approval for such changes must be submitted
to FDA or other regulatory authority. Additionally, FDA regulates post-
approval promotional labeling and advertising activities to assure that such
activities are being conducted in conformity with statutory and regulatory
requirements. Failure to adhere to such requirements can result in regulatory
actions which could have a material adverse effect on the Company's business,
results of operations and financial condition.
 
 Other Regulation
 
  The Prescription Drug Marketing Act (the "PDMA"), which amends various
sections of the FDCA, imposes requirements and limitations upon drug sampling
and prohibits states from licensing distributors of prescription drugs unless
the state licensing program meets certain federal guidelines that include,
among other things, state licensing of wholesale distributors of prescription
drugs under federal guidelines that include minimum standards for storage,
handling and record keeping. In addition, the PDMA sets forth civil and
criminal penalties for violations of these and other provisions. Various
sections of the PDMA are still being implemented by FDA and the states.
Nevertheless, failure by the Company's distributors to comply with the
requirements of
 
                                      42
<PAGE>
 
the PDMA could have a material adverse effect on the Company's business,
results of operations and financial condition. See "Risk Factors--Dependence
on Regulatory Approval and Compliance" and "Risk Factors--Pending Regulatory
Matters."
 
  Manufacturers of marketed drugs must comply with cGMP regulations and other
applicable laws and regulations required by FDA, the Drug Enforcement Agency,
the Environmental Protection Agency and other regulatory agencies. Failure to
do so could lead to sanctions, which may include an injunction suspending
manufacturing, the seizure of drug products and the refusal to approve
additional marketing applications. Manufacturers of controlled substances are
also subject to the licensing, quota and regulatory requirements of the
Controlled Substances Act. Failure to comply with the Controlled Substances
Act and the regulations promulgated thereunder could subject the Company to
loss or suspension of those licenses and to civil or criminal penalties. The
Company seeks to ensure that any third party with whom it contracts for
product manufacturing or packaging will comply with cGMPs. FDA conducts
periodic inspections to ensure compliance with these rules. However, there can
be no assurance that any such third parties will be found to be in compliance
with cGMP standards. Any such non-compliance could result in a temporary or
permanent interruption in the development and testing of the Company's planned
products or in the marketing of approved products, as well as increased costs.
Such non-compliance could have a material adverse effect on the Company's
business, results of operations and financial condition.
 
  Products marketed outside the United States, which are manufactured in the
United States, are subject to certain FDA regulations as well as regulation by
the country in which the products are to be sold. The Company is required to
obtain approval for and maintain compliance with applicable regulations
relating to the marketing of its products outside the United States. There can
be no assurance that any such approval may be obtained or such compliance
maintained.
 
PRODUCT LIABILITY; INSURANCE
 
  The testing, manufacturing and distribution of the Company's products
involve a risk of product liability claims. Pursuant to the Company's various
insurance policies, the Company is self-insured up to the first $500,000 of
claims for each occurrence and $2,500,000 in the aggregate per policy year.
Although no assurance can be given, the Company believes that its product
liability insurance is adequate. Product liability insurance, however, could
cease to be available or could cease to be available on acceptable terms,
either as a function of the market for product liability insurance for
pharmaceutical companies or the Company's own claims experience. See "Risk
Factors--Risk of Product Liability Claims; No Assurance of Adequate
Insurance."
 
EMPLOYEES
 
  At September 1997, the Company had approximately 1,850 employees, of which
830 were engaged in manufacturing, 380 were engaged in quality control and
quality assurance, 240 were engaged in administration, finance and human
resources, 140 were engaged in research and product development, 140 were
engaged in sales and marketing, 80 were engaged in distribution and 40 were
engaged in regulatory affairs. No employee is represented by a union, and the
Company has never experienced a work stoppage. Management believes its
relationship with its employees is good.
 
LEGAL PROCEEDINGS
 
  The Company is a defendant in several product liability cases typical for a
company in the pharmaceutical industry. The Company also is involved in other
proceedings and claims of various types. Management believes the disposition
of these matters will not have a material adverse effect on the Company.
 
  In October 1997, the Company received a subpoena from the Department of
Health and Human Services, Office of Inspector General seeking pricing
information for two products formerly marketed by the Company, vinblastine
sulfate and vincristine sulfate. The Company is aware of a number of other
pharmaceutical manufacturers and distributors that have been served with
similar subpoenas, which the Company believes is in connection with a
government investigation into claims for reimbursement by Medicare and/or
Medicaid. The Company intends to comply with the subpoena.

EMPLOYMENT AGREEMENTS
 
  The Company entered into an employment agreement with Martin Sperber dated
September 30, 1994 pursuant to which Mr. Sperber serves as Chairman of the
Board, Chief Executive Officer and President of the Company. Under this
agreement, the term of Mr. Sperber's employment commenced on January 1, 1994
and terminates on January 1, 1999, unless earlier terminated by the death of
Mr. Sperber, by action of the Board of Directors with or without cause, due to
the disability of Mr. Sperber or by Mr. Sperber upon 30 days written notice or
a material breach by the Company of his employment or stock option agreement
that is not cured within 30 days. If Mr. Sperber is terminated without cause,
in addition to all accrued but unpaid compensation to the date of termination,
he is entitled to receive as severance compensation his base salary from the
date of termination through January 1, 1999 and an amount equal to the product
of (i) a fraction, the numerator of which is the amount of earned incentive
compensation for the last full year before termination and the denominator of
which is 365 and (ii) the number of days from termination until January 1,
1999. If Mr. Sperber voluntarily terminates his employment prior to January 1,
1999 (other than for an uncured breach by the Company), he is only entitled to
such severance pay as is determined by the Compensation Committee. Mr. Sperber
currently receives base annual compensation of $700,000. Mr. Sperber may also
receive incentive compensation in an amount to be determined by the
Compensation Committee. If Mr. Sperber's employment is terminated prior to
January 1, 1999, such incentive compensation shall be based on objective
criteria established by the Compensation Committee or $250,000 plus the
product of (x) the fraction derived by dividing (i) the sum of the actual cash
incentive compensation earned by each of the three most senior executives of
the Company other than Mr. Sperber in the year Mr. Sperber's employment is
terminated less the sum of the minimum cash incentive compensation
contemplated for such executives for such year, by (ii) the sum of the maximum
cash incentive compensation contemplated for such executives for such year
less the sum of the minimum cash incentive compensation contemplated for such
executives for such year and (y) $250,000. Mr. Sperber is prohibited from
competing with the Company during the term of the agreement and until the
second anniversary of the date the Company makes its final base salary payment
to Mr. Sperber pursuant to the agreement.
 
  Following termination of Mr. Sperber's employment other than for cause, Mr.
Sperber will be entitled during his lifetime and for the life of his spouse to
continue to participate in, or receive benefits that, on an after-tax basis,
are the same as those under all medical and dental benefit plans, policies and
programs in effect at the termination of his employment. In addition, unless
Mr. Sperber's employment is terminated for cause, Mr. Sperber will be entitled
to an annual pension, beginning after the termination of his employment and
continuing until the later of the death of Mr. Sperber or his spouse, in an
amount equal to 45% (or 40%, if Mr. Sperber's employment is terminated due to
his voluntary resignation) of the average total cash compensation for the
highest three of the last five years prior to termination, reduced generally
by the sum of the amount Mr. Sperber would be entitled to receive under all of
the Company's qualified retirement plans within the meaning of Section 401(a)
of the Internal Revenue Code and under Social Security if he commenced
receiving such benefit payments at age 65. See "--Stock Options."
 
  The Company entered an Option Agreement with Mr. Sperber dated September 30,
1994 under which Mr. Sperber was granted, as a key employee pursuant to the
Company's 1993 Stock Option Plan, a non-qualified option to purchase from the
Company up to 4,795 shares of Common Stock at a price of $2,000 per share. The
option expires on the earlier of September 30, 2004 or upon Termination of
Employment (as defined in the 1993 Stock Option Plan). In the event of Mr.
Sperber's death, disability, retirement or termination without cause, the
option remains exercisable for one year (but may be extended by the Company at
its discretion). Upon termination of Mr. Sperber's employment for cause (or
discovery of justification for termination for cause after termination for
another reason), all outstanding options are immediately cancelled. In the
event Mr. Sperber's employment is terminated for any other reason, all
outstanding options will remain exercisable for three months from the date of
termination (but may be extended at the discretion of the Company).
 
  Pursuant to an employment agreement with Marsam dated July 28, 1995, to
which the Company agreed to be bound by certain provisions, Marvin Samson was
appointed an Executive Vice President and Director of the Company, as well as
President, Chief Executive Officer and Chief Operating Officer of Marsam, for
an initial
 
                                      47
<PAGE>
 
term that commenced on the date of the Marsam Acquisition and terminates on
the fifth anniversary of that date (the "Initial Term"), which term is
automatically extended for one-year periods unless earlier terminated upon 180
days advance written notice by either party. During the Initial Term, Mr.
Samson may terminate the agreement at any time, but the Company may only
terminate Mr. Samson for cause. If the Company terminates Mr. Samson's
employment other than for cause during the Initial Term, Mr. Samson is
entitled to severance compensation in the amount of his annual salary, as well
as comparable health and disability insurance coverage (or reimbursement
therefor), for the remainder of the Initial Term (or any extension thereof).
If Mr. Samson terminates the agreement prior to the end of the Initial Term,
he is entitled to continue receiving 50% of his salary and comparable
insurance benefits (or reimbursement therefor) starting on the date of
termination and ending on the earlier of the third anniversary of the
termination or the fifth anniversary of the Marsam Acquisition. Mr. Samson
currently receives base annual compensation of $400,000. In 1996, the
Company's Board of Directors determined to award a $70,000 bonus to Mr.
Samson, payable to Mr. Samson in 1997. Mr. Samson is also entitled to
participate in and receive benefits from the Company's bonus, stock option,
pension, profit-sharing, insurance and other employee benefit plans. In
addition, the agreement provides that during any time when the Company is
obligated to pay Mr. Samson a salary or consulting fee, Mr. Samson is also
entitled to an automobile, or, at the Company's option, an automobile
allowance. Mr. Samson is prohibited from competing with the Company (or owning
more than 3% of the outstanding equity of a competing business) during the
term of his employment or consultancy with the Company, during any period in
which the Company is making severance compensation payments or upon
termination for cause by the Company until the earlier of the sixth
anniversary of the Marsam Acquisition and the fourth anniversary of the
termination.
 
  The Company, at its option, may retain Mr. Samson as a consultant for a
period of one year after the Initial Term (or any extension thereof) or after
Mr. Samson terminates the agreement. As a consultant, Mr. Samson is entitled
to receive a consulting fee in an amount equal to his base salary immediately
prior to termination, as well as comparable health and disability insurance
coverage (or reimbursement therefor). Such consulting fee may be reduced
dollar-for-dollar by any compensation received by Mr. Samson for other
employment that he is engaged in at the time. The Company, at its option, may
terminate the consultancy upon 30 days prior written notice.
 
  The agreement also provides that Mr. Samson, having been elected a director
of the Company effective on the date of the Marsam Acquisition, is entitled to
have his name included in the slate of the Company's management nominees for
re-election as a director during the term of the agreement. Mr. Samson is also
entitled to designate three of Marsam's seven board members.
 
  Following termination of Mr. Samson's employment other than for cause, Mr.
Samson will be entitled to an annual pension for a period of ten years. A
compensation continuation agreement dated October 19, 1991 provides for a
payment in the first year equal to 100% of his prior year base salary and a
payment equal to 50% of his base salary for the subsequent nine years. The
Company has also agreed to provide certain benefits to Mr. Samson in the form
of payments on the split dollar life insurance contract insuring the lives of
Mr. Samson and his wife.
 
  The Company entered into an employment agreement with Dariush Ashrafi dated
May 1, 1995, pursuant to which Mr. Ashrafi serves as Executive Vice President
and Chief Financial Officer of the Company. Under this agreement, the term of
Mr. Ashrafi's employment began on May 1, 1995 and terminates 60 days after
either Mr. Ashrafi or the Company gives written notice that he or it does not
wish to continue the employment, unless earlier terminated for cause or upon
the death or disability of Mr. Ashrafi. Mr. Ashrafi currently receives annual
base compensation of $341,000. In 1996, the Company's Board of Directors
determined to award a $59,700 bonus to Mr. Ashrafi, payable to Mr. Ashrafi in
1997. Pursuant to a deferred compensation agreement dated April 17, 1995,
between the Company and Mr. Ashrafi, Mr. Ashrafi is entitled to receive a
bonus of $300,000, payable in quarterly payments in the amount of $75,000. If
Mr. Ashrafi's employment with the Company is terminated under certain
circumstances, he is entitled to receive 100% of his base salary and annual
cash bonus paid or payable by the Company to him in respect of the last full
fiscal year preceding the termination date as one lump
 
                                      48
<PAGE>
 
sum payment. Further, if Mr. Ashrafi is terminated other than for cause or
disability, or if he voluntarily terminates his employment in certain
instances, he is entitled to receive basic health and medical benefits until
the earlier of one year following termination and his full-time employment
elsewhere.
 
  The Company entered into an employment agreement with Paul Feuerman dated
November 29, 1993, pursuant to which Mr. Feuerman serves as Senior Vice
President and General Counsel to the Company. Under this agreement, the term
of Mr. Feuerman's employment began on November 29, 1993 and terminates 60 days
after either Mr. Feuerman or the Company gives written notice that he or it
does not wish to continue the employment, unless earlier terminated for cause
or upon the death or disability of Mr. Feuerman. Mr. Feuerman currently
receives annual base compensation of $225,000. In 1996, the Company's Board of
Directors determined to award a $32,400 bonus, payable to Mr. Feuerman in
1997. Pursuant to a deferred compensation agreement dated August 8, 1996,
between the Company and Mr. Feuerman, Mr. Feuerman is entitled to receive a
bonus of $500,000, payable in two annual installments of $100,000 each
followed by two annual installments of $150,000 each. If Mr. Feuerman's
employment with the Company is terminated under certain circumstances, he is
entitled to receive 100% of his base salary and annual cash bonus paid or
payable by the Company to him in respect of the last full fiscal year
preceding the termination date as one lump sum payment. Further, if Mr.

Common Stock, subject to adjustment under certain circumstances. In addition,
the Company's 1993 Stock Option Plan (the "1993 Plan") provided for the
granting of options to purchase not more than an aggregate of 27,400 shares of
Common Stock, subject to adjustment under certain circumstances. In addition,
the Company's 1995 Non-Employee Director Stock Option Plan (the "Non-Employee
Director Plan") provides for the granting of options to purchase not more than
an aggregate of 1,000 shares of Common Stock, subject to adjustment under
certain circumstances. Although options granted under the 1993 Plan to
purchase 25,586 shares are still outstanding, no further grants will be made
pursuant to the 1993 Plan. Some or all of the options granted under the 1997
Plan may be "incentive stock options" within the meaning of section 422 of the
Internal Revenue Code of 1986 (the "Code"). The Company has granted options to
purchase 4,252 shares under the 1997 Plan at the then fair market value.
 
  The Compensation Committee administers the 1997 Plan. The Compensation
Committee has full power and authority to interpret the 1997 Plan, set the
terms and conditions of individual options and supervise the administration of
the 1997 Plan.
 
  The Compensation Committee determines, subject to the provisions of the 1997
Plan, to whom options are granted, the number of shares of Common Stock
subject to an option, whether stock options will be incentive or non-
qualified, the exercise price of the options (which, in the case of non-
qualified options, may be less than the fair market value of the shares on the
date of grant) and the period during which options may be exercised. All
employees of the Company are eligible to participate in the 1997 Plan. No
options may be granted under the 1997 Plan after March 3, 2007.

  The Compensation Committee may amend the 1997 Plan from time to time.
However, the Compensation Committee may not, without stockholder approval,
amend the 1997 Plan to increase the number of shares of Common Stock under the
1997 Plan (except for changes in capitalization as specified in the 1997
Plan).
 
  The Non-Employee Director Plan provides for automatic annual grants of
options to purchase shares of the Company's Common Stock to non-employee
directors of the Company in amounts calculated using a formula provided in the
plan. The Company has granted options to purchase 189 shares of Common Stock
under the Non-Employee Director Plan.
 
  The Board of Directors of the Company may amend the Non-Employee Director
Plan from time to time. However, the Board of Directors may not, without
stockholder approval, amend the plan to increase the number of shares of
Common Stock available for option grants under the plan (except for changes in
capitalization specified in the plan).
 
CERTAIN OTHER EMPLOYEE BENEFIT PLANS
 
  The Company maintains the Retirement Plan of Schein Pharmaceutical, Inc. &
Affiliates (the "Company Retirement Plan"), under which employees (other than
temporary employees) of the Company may participate on the first day of the
first pay period after completing six consecutive calendar months during which
they complete at least 500 hours of service. Effective July 1, 1996, the
Company Retirement Plan became the successor to the Marsam Pharmaceuticals
Retirement Plan.
 
  Participants generally may make basic contributions to the Company
Retirement Plan, by salary deduction, of up to 14% of their compensation from
the Company, subject to applicable federal tax limitations ($9,500 for the
1997 plan year, subject to cost of living adjustments); the amount of a
participant's basic contribution is generally excluded from gross income for
federal or state income tax purposes. The Company makes a mandatory matching
contribution to the Company Retirement Plan of $.25 for each dollar
contributed to the Company Retirement Plan as a basic contribution, up to the
first 3% of a participant's contribution; the Company also may make additional
matching contributions and may make other non-matching contributions to the
Company Retirement Plan at the discretion of the Board of Directors. In 1997,
the Company made a discretionary, non-matching contribution under the Company
Retirement Plan for 1996 equal to 5% of compensation.
 
  Participants in the Company Retirement Plan have a 100% vested and
nonforfeitable interest in the value of their basic contribution and the
Company's matching contribution, and they acquire a 100% vested and
nonforfeitable interest in the Company's non-matching amounts at retirement,
death, disability or termination pursuant to an employee reduction plan. If
their employment terminates prior to the normal retirement date for any other
reason, participants acquire a 10% vested and nonforfeitable interest in the
Company's non-matching contribution amounts for each of the first four years
of service; and a 20% vested and nonforfeitable interest in the Company's non-
matching contribution amounts for each of the fifth, sixth and seventh years
of service; accordingly, after seven years of service, participants have a
100% vested and nonforfeitable interest in the value of the Company's non-
matching contribution amounts.
 
  Participants are entitled to receive the amounts in their Company Retirement
Plan accounts in a single lump-sum payment on death, disability, retirement or
termination of employment. At the election of the participant, the
participant's Company Retirement Plan account is eligible for payment in
installments of either 5 or 10 years. In certain circumstances, participants
may receive loans and hardship withdrawals from their accounts in the Company
Retirement Plan.
 
  Supplemental Retirement Plan. The Company maintains a Supplemental
Retirement Plan (the "Supplemental Retirement Plan"). Under the Supplemental
Retirement Plan, the Company pays non-qualified deferred compensation to
certain of its employees consisting of benefits based on annual compensation
in excess of limitations imposed by the Code on contributions under the
Company Retirement Plan. The Supplemental Retirement Plan is an unfunded
"pension benefit plan" subject to the Employee Retirement Income Security Act
of 1974, as amended.
 
 
                                      50
<PAGE>
 
  Split Dollar Life Insurance Plan. The Company maintains a Split Dollar Life
Insurance Plan (the "Life Insurance Plan"). Under the Life Insurance Plan,
each participating officer owns a life insurance policy. Each policy is
designed to provide at age 65 an annuity equal to a specified percentage of
the participant's projected average annual salary for the final three years of
employment (less Social Security benefits and certain benefits under the
Company Retirement Plan). A cash surrender value, which is owned by the
individual and designed to fund the annuity, accumulates under each
participant's policy. The Company and the employee will share the cost of
premiums. The premiums advanced by the Company will be repaid out of the cash
value of the policies.
 
  1993 Book Equity Appreciation Rights Program. The Company maintains a Book
Equity Appreciation Rights Program (the "Program") to allow certain employees
to benefit from an increase in the Company's book value (calculated according
to a formula defined in the Program). All participants are fully vested in
their book equity appreciation rights ("BEARs"). The Company does not intend
to make any additional grants of BEARs.

                             CERTAIN TRANSACTIONS
 
  In 1994, the Company entered into a Heads of Agreement with Bayer
Corporation and Bayer A.G. (collectively, "Bayer"), pursuant to which the
Company and Bayer committed together to explore business opportunities for the
U.S. and abroad.
 
  In 1994, the Company entered into a three-year co-promotion agreement with
Bayer covering the Company's INFeD product. Under the terms of the agreement,
in 1994, 1995 and 1996, in exchange for promotional support, the Company
shared with Bayer the net profits of INFeD in excess of specified threshold
amounts. In early 1997, this agreement was amended and extended to December
1997. The parties are currently negotiating a further extension of this
agreement. This amended agreement provides that in exchange for promotional
support, the Company pays Bayer a fixed dollar amount plus a fixed percentage
of sales above a threshold amount. The Company incurred selling expenses under
these agreements of approximately $3.0 million in 1996 and $2.9 million for
the first nine months of 1997. There were no selling expenses under the first
agreement for 1994 and 1995. See "--Restructuring Agreements."
 
  Since 1994, the Company and Bayer, through their respective affiliates, have
entered into several joint ventures to own, manage or develop generic
pharmaceutical businesses outside of the U.S. Each of Schein and Bayer have
contributed various assets and rights and funded the operations of these
ventures, and in certain circumstances have guaranteed certain liabilities of
these ventures, such as leases and lines of credit. It is contemplated that
the Company and Bayer will sell products to certain of these ventures for
resale in their local markets. Bayer and Schein are each currently evaluating
the extent of their continued participation in certain of these ventures.
 
  The Company, together with the Pharmaceutical, Consumer Healthcare, Afga
Film and Diagnostics divisions of Bayer, has created a collaboration called
Bayer Healthcare Partners. Bayer Healthcare Partners is a marketing tool
through which the various participants combine their sales efforts to offer a
package of goods and services designed to be more attractive to a customer,
most likely a managed health care provider. The participants share in the
costs and profits associated with sales of the covered products to that
customer.
 
  Since 1985, the Company has had a series of non-exclusive agreements
(collectively, the "Consulting Agreement") with the Consultant. Under the
Consulting Agreement, the Consultant and the Company have identified certain
patents on branded pharmaceutical products that might be susceptible to a
challenge, and the Consultant has acted as litigation counsel or advising
counsel to the Company in those instances where the Company decided to proceed
with a patent challenge. For projects in which the Consultant has rendered an
opinion, the Company pays the Consultant half the adjusted gross profit from
the Company's sale of generic versions of the patented product until the date
on which the patent would normally have expired or half the proceeds of any
settlement. In 1995 and 1996, the Company recorded in the aggregate net
product sales and settlements from patent challenges of $106.0 million and
related gross profits of $62.6 million (after deducting payments to the
Consultant of $17.4 million). See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Results of Operations."
 
  The Consultant's services are provided on a non-exclusive basis to the
Company. The Consulting Agreement does not have a specific term and continues
until the current projects under the Consulting Agreement are completed and
all payments due to the Consultant are made. There are two current projects
under the Consulting Agreement, one of which has resulted in a pending patent
challenge initiated by the Company. In accordance with the Consultant's right
to delegate responsibility for defending patent challenge litigation to other
counsel selected with the consent of the Company, responsibility for the
pending patent challenge has been delegated to other counsel. The Consultant
may terminate the Consulting Agreement for certain specified reasons at any
time. Without regard to who terminates the Consulting Agreement or the reasons
therefor, the Consultant will be entitled to payment in conjunction with any
sales or settlements with respect to any patented product for which the
Consultant has previously rendered an opinion setting forth the basis for a
possible patent challenge. The Consultant has rendered opinions with respect
to each of the two patented drug products that are the
 
                                      52
<PAGE>
 
respective subjects of the current projects under the Consulting Agreement,
and the Company will owe the Consultant payments to the extent that the
Company successfully develops one or both of these products and challenges the
applicable patents and thereafter markets one or both of these products, or
otherwise favorably settles any such challenge.
 
  In the conduct of its business, the Company sells pharmaceutical products to
Henry Schein, Inc. for distribution to its customers. Net sales to Henry
Schein, Inc. were $6.4 million, $5.3 million and $8.6 million in 1994, 1995
and 1996, respectively, and $5.5 million and $5.4 million for the nine months
ended September 1996 and the nine months ended September 1997, respectively.
Other than certain common stockholders, there is no affiliation between Henry
Schein, Inc. and the Company, and all transactions between the Company and
Henry Schein, Inc. are on an arm's-length basis.
 
  The Company has signed a non-binding letter dated October 7, 1997 with
Cheminor and Reddy outlining the parties' intent to enter into a strategic
alliance agreement. As part of the contemplated arrangement, Cheminor could
purchase shares of the Company's Common Stock, once the shares are publicly
traded, at fair market value; the purchase price could be payable from the
profits otherwise due Cheminor from the alliance. Cheminor would have certain
rights to acquire additional shares from time to time, at fair market value,
to maintain its percentage interest in the Company. In addition, Cheminor
would have representation on the Company's Board of Directors consistent with
its equity investment through the purchase of the Company's shares once they
are publicly traded. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."
 
  In connection with Mr. Ashrafi's relocation, the Company loaned Mr. Ashrafi
$150,000 at an interest rate of 6.875% per annum evidenced by a promissory
note dated May 31, 1996. As of September 1997, an aggregate principal amount
of $150,000 was outstanding on that loan.
 
  Richard L. Goldberg, who is a Director of the Company, is a member of
Proskauer Rose LLP, which has been retained by the Company to provide legal
services.
 
 Restructuring Agreements
 
  At the time of Bayer Corporation's acquisition of its 28.3% interest in the
Company, the Company, Bayer Corporation, Mr. Sperber, and certain other
principal stockholders entered into certain agreements (the "Restructuring
Agreements") relating to the governance of the Company and certain other
matters.
 
  Agreements Relating to Control of the Company. The Restructuring Agreements
provide that, until the earlier of March 1, 2000 and the effective date of a
merger, consolidation or combination that results in the voting trustee
(currently Mr. Sperber) (the "Voting Trustee") neither holding the position of
chairman of the board, president, chief executive officer or chief operating
officer of the resulting entity nor having the right to designate a majority
of the members of the board of the resulting entity (such earlier date, the
"Voting Trust Termination Date"), the Voting Trustee will have the right to
vote, or direct the vote of, all the shares of Common Stock owned by Marvin
Schein, Pamela Schein and Pamela Joseph and certain trusts established by them
or for their issue (collectively, the "Family Stockholders"). As a result of
the foregoing, the Voting Trustee as a practical matter will be able to
control substantially all matters requiring stockholder approval, including
the election of directors, until March 1, 2000. The Restructuring Agreements
provide that Mr. Sperber may designate certain individuals to succeed him as
Voting Trustee under the Restructuring Agreements.
 
  The Restructuring Agreements provide that, until Bayer Corporation owns less
than 10% of the Company's outstanding Common Stock (the "Governance
Termination Date"), Bayer Corporation shall be entitled to nominate a number
of members of the Board of Directors of the Company, rounded down to the
nearest whole number, equal to the product of (a) the number of members of the
Board of Directors and (b) its percentage stockholdings of Common Stock of the
Company at the time of nomination. The Voting Trustee is entitled, until the
Voting Trust Termination Date, to nominate the balance of the members of the
Board of Directors. Until May 15, 2001, the Voting Trustee and the other
Continuing Stockholders (as defined herein) (to the extent their shares of
Common Stock are not voted by the Voting Trustee) must vote for the election
of Bayer Corporation's
 
                                      53
<PAGE>
 
nominee(s). Until the Voting Trust Termination Date, Bayer Corporation and the
Continuing Stockholders (to the extent their shares of Common Stock are not
voted by the Voting Trustee) must vote for the election of the Voting
Trustee's nominees.
 
  Until May 15, 2001, the Company may not, without Bayer Corporation's
consent, among other things, (a) own, manage or operate any business not
principally engaged in a segment of the pharmaceutical or health care industry
or any business ancillary thereto, (b) amend or restate the Company's charter
or by-laws to require more than majority approval to elect a majority of the
Board of Directors, merge, consolidate or sell all or substantially all the
Company's assets or (c) engage in transactions with any affiliate on terms
more favorable to the affiliate than could be obtained in an arm's-length
transactions, other than intercompany transactions and transactions under or
identified in the Restructuring Agreements. In addition, until the earlier of
(i) the Governance Termination Date and (ii) the date on which the shares of
the Company's Common Stock that are held by more than 300 persons who are
neither current stockholders, their permitted transferees nor employees of the
Company have a total market value in excess of $100.0 million (the "Qualified
Public Offering Date"), the Company may not undertake certain other actions
without the consent of Bayer Corporation.
 
  The Restructuring Agreements include the Standstill, which imposes certain
restrictions on Bayer Corporation and its affiliates until May 15, 2001 (the
"Standstill Period"). Under the Standstill, Bayer Corporation and its
affiliates may not, among other things, (a) acquire, announce an intention to
acquire or offer to acquire any assets of the Company or its subsidiaries
(other than in the ordinary course) or equity securities of the Company, (b)
participate in or encourage the formation of a group or entity that seeks to
acquire equity securities of the Company, (c) solicit proxies or become a
participant in any election contest with respect to the Company, (d) initiate
or otherwise solicit stockholders for the approval of stockholder proposals or
induce any other person to initiate any stockholder proposal, (e) seek to
place designees on, or remove any member of, the Board or Directors, (f)
deposit any equity securities in a voting trust or like arrangement, (g) seek
to control the management of the Company or negotiate with any person with
respect to any form of extraordinary transaction with the Company or other
transaction not in the ordinary course of business, or be involved in a tender
or exchange offer or other attempt to violate the Standstill or (h) request
the Company or otherwise seek to amend or waive any provision of the
Standstill.
 
  After the Standstill Period, Bayer Corporation has the right, exercisable
within six months of the end of the Standstill Period and if there is an
insufficient number of shares of Common Stock available on the open market for
Bayer Corporation to acquire a majority of the outstanding Common Stock of the
Company on the open market, to acquire from the Family Stockholders and then
from the Company, a number of shares that should enable Bayer Corporation to
own a majority of the outstanding Common Stock of the Company.
 
  Notwithstanding the Standstill, Bayer Corporation generally may acquire
Common Stock (a) unless Bayer Corporation has sold shares of Common Stock
other than to a Permitted Assignee, (I) in connection with its exercise of
certain preemptive rights or (II) if, after the Qualified Public Offering
Date, necessary to own at least 21% more of the Company's outstanding Common
Stock than certain 10% holders and (b) up to the "New Percentage," defined as:
30% of the Company's outstanding common stock between May 15, 1997 and May 15,
1999; 33 1/3% between May 16, 1999 and May 15, 2000; and 36 2/3% between May
16, 2000 and the end of the Standstill Period.
 
  Under the Restructuring Agreements, if Bayer Corporation and its affiliates
for any reason acquire shares in excess of the New Percentage, until May 15,
2001, Bayer Corporation shall vote those excess shares in accordance with the
Voting Trustee's instructions and those excess shares will not be considered
in determining the number of director nominees to which Bayer Corporation is
entitled.
 
  Under the Restructuring Agreements, each of Marvin Schein, Pamela Schein and
Pamela Joseph has agreed that such individual, and such individual's Family
Group (as defined herein), shall not acquire shares if, as a consequence of
the acquisition such individual, together with such individual's Family Group,
owns in excess of (a) in the case of Marvin Schein and his Family Group,
35.85% of the Common Stock of the Company, (b) in the case of Pamela Schein
and her Family Group, 27.55% of the Common Stock of the Company and (c) in the
case of Pamela Joseph and her Family Group, 12.97% of the Common Stock of the
Company.
 
                                      54
<PAGE>
 
  Restrictions on Transfer. The Restructuring Agreements generally provide
that Marvin Schein, Pamela Schein, Pamela Joseph, Mr. Sperber, Stanley
Bergman, certain trusts established by these individuals (collectively, the
"Continuing Stockholders") and certain of their transferees may not transfer
any of their shares until March 1, 2000, except (a) pursuant to Rule 144 under
the Securities Act, but subject to volume limitations intended to equal the
volume limitations applicable to affiliates as set forth in Rule 144(e)(1)
(the "Maximum Rule 144 Sales Amount"), (b) in a wide distribution in an amount
that exceeds the Maximum Rule 144 Sales Amount, regardless of whether the
seller is an affiliate or Rule 144(k) is applicable, in connection with which
the seller or the underwriter confirms that no direct or indirect purchaser in
that distribution is intended to acquire more than the Maximum Rule 144 Sales
Amount, (c) to certain family members of the transferor, related trusts or
estates, or other entities owned exclusively by such transferor, family
members, trusts or estates (collectively, a "Family Group"), (d) in private
placements, to persons who own fewer than 1% of the outstanding common stock
of the Company immediately prior to the transfer and who are not affiliated
with or Family Group members of the transferor, of no more than (I) 1% of the
outstanding Common Stock of the Company to any one person, its affiliates or
Family Group members in any three-month period and (II) 4% of the outstanding
Common Stock of the Company to all persons in any twelve-month period, (e) in
connection with the exercise of certain registration rights granted to the
Company's stockholders under the Restructuring Agreements, but only if, to the
extent the number of shares sold exceeds the Maximum Rule 144 Sales Amount, it
is confirmed to the Company that it is intended that no purchaser will acquire
more than the Maximum Rule 144 Sales Amount, (f) pledges to a financial
institution or transfers to a financial institution in the exercise of its
pledge rights, (g) to Bayer Corporation as provided under the Restructuring
Agreements, (h) pursuant to a merger or a consolidation that has been approved
by the Board of Directors and stockholders of the Company, (i) in a tender
offer in which Mr. Sperber (or any member of his Family Group who acquired
shares from Mr. Sperber) sells shares and (j) in a tender offer for a majority
of the shares of Common Stock of the Company by a bidder not affiliated with
Bayer A.G., if Bayer A.G. and its affiliates have failed to pursue a tender
offer or other acquisition permitted under the Restructuring Agreements. In
addition, Continuing Stockholders have been granted registration rights.
 
  In addition to the above restrictions, the Restructuring Agreements
generally provide that Bayer Corporation and the Continuing Stockholders may
not transfer any of their shares until May 15, 1999. However, Bayer
Corporation may transfer its shares in connection with certain registration
rights granted to Bayer Corporation under the Restructuring Agreements or to a
Permitted Assignee. The Continuing Stockholders may transfer their shares as
provided in the preceding paragraph. A "Permitted Assignee" is (a) a successor
to all or substantially all the business and assets of Bayer Corporation or a
majority-owned subsidiary of Bayer A.G. who agrees to be bound by the
Restructuring Agreements, (b) with respect to certain preemptive rights,
rights of first refusal and rights of first offer, a single purchaser who,
immediately after the purchase and for 60 days thereafter, owns at least 10%
of the shares then owned by Bayer Corporation and who agrees to be bound by
the Standstill and (c) with respect to certain registration rights, any person
referred to in (a) above and up to three non-affiliated purchasers who,
immediately after the respective purchases and for 60 days thereafter, own in
the aggregate at least 20% of the shares then owned by Bayer Corporation and
who agree to be bound by the Standstill.
 
  If Bayer Corporation sells any of its shares in the Company to any
unaffiliated third party, then the following of Bayer Corporation's rights
under the Restructuring Agreements terminate: the right to consent to certain
transactions of the Company; the right to purchase additional shares on
Company issuances of equity securities; the right to acquire shares to
maintain an ownership percentage of more than 21% of outstanding shares over
certain 10% holders; the right to acquire from the Company or the Family
Stockholders under certain circumstances after the Standstill Period, shares
for a controlling interest in the Company; and rights of first refusal with
regard to share transfers by Continuing Stockholders. However, certain of
those rights (i.e., rights to purchase additional shares on Company issuances
of equity securities and rights of first refusal) may be transferred to a
single purchaser who owns at least 10% of the Company's shares then owned by
Bayer Corporation and who agrees to be bound by the Standstill obligations.
 
  Mr. Sperber and Mr. Bergman may not transfer any of their shares to Bayer
A.G. except in certain open market transactions and except to the extent that
Bayer A.G. first offered to purchase such shares from the Family Stockholders
and the Family Stockholders did not sell such shares.
 
                                      55
<PAGE>
 
  The Company may not transfer any of its shares to Bayer A.G., except to the
extent that Bayer A.G. is entitled to purchase shares under the Restructuring
Agreements and those shares are not purchased in the open market or from
Family Stockholders.
 
  Rights of Inclusion and First Refusal. The Restructuring Agreements provide
that, if at any time prior to the Voting Trust Termination Date, any Family
Stockholder or Family Group member (an "Offeree") receives an offer from a
third party to purchase some or all of the Offeree's shares of Common Stock,
the Offeree wishes to sell the shares (other than in a transaction described
in clauses (a) through (i) of the first paragraph of "--Restrictions on
Transfer" above) and Mr. Sperber, as Voting Trustee, consents to the
transaction, the Company or its designee shall have the right of first refusal
to purchase those shares on the same terms as in the third party offer.
 
  Under the Restructuring Agreements, if the Company fails to exercise its
right of first refusal and Bayer Corporation has not sold shares other than to
a Permitted Assignee, such right will be deemed assigned to Bayer Corporation,
provided that (a) the stockholdings of Bayer A.G. may not as a result of its
exercising such right exceed the New Percentage and (b) if as a result of its
exercising such right, Bayer A.G. would own a majority of the shares of Common
Stock of the Company, Bayer Corporation will exercise such right at a price
per share equal to the greater of (I) the price contained in the third party
offer and (II) the price determined by an investment banking firm, who will
take into consideration, among other things, that control of the Company will
pass at that time to Bayer A.G.
 
  In addition, if, prior to the end of the Standstill or the time that Bayer
Corporation sells shares other than to a Permitted Assignee, the Company is
not entitled to exercise the right of first refusal described above and a
Continuing Stockholder is permitted under the Restructuring Agreements, and in
good faith wishes, to sell shares of Common Stock to a third party (other than
sales under Rule 144 under the Securities Act and sales under clauses (b), (i)
and (j) of the first paragraph of "--Restrictions on Transfer" above), Bayer
Corporation shall have the right of first offer to purchase those shares of
Common Stock on the same terms as the Continuing Stockholder wishes to sell
the shares of Common Stock.
 
  The Restructuring Agreements provide that if at any time prior to the
earlier of the second anniversary of the Qualified Public Offering Date and
May 15, 2001, Bayer is permitted under the Restructuring Agreements, and in
good faith wishes, to sell shares of Common Stock to a third party, the
Company and the Continuing Stockholders shall have the right of first offer to
purchase those shares of Common Stock on the same terms as the Bayer wishes to
sell the shares of Common Stock.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
  As of September 5, 1995, the Company entered into the Senior Credit
Agreement with a group of lenders. The Chase Manhattan Bank (formerly Chemical
Bank) acts as credit agent thereunder. The Senior Credit Agreement, as
amended, provides a term loan facility of $250.0 million and a revolving
credit facility of $100.0 million, each maturing on December 31, 2001. As of
September 27, 1997, the Company had pre-paid $120 million of the term loan
portion of the Senior Credit Agreement and had permanently reduced the
lenders' commitments with respect thereto and had outstandings under the
revolving credit facility of approximately $26.0 million.
 
  The Company's borrowing can be based, at the option of the Company, on a
spread above LIBOR or an alternate base rate ("ABR"). The interest rate spread
applicable to term loan and revolving credit borrowings fluctuates based on
leverage. The spread, in the case of LIBOR loans, can range from 0.75% to
2.50% and, in the case of ABR loans, from 0% to 1.50%. The ABR is based on a
per annum rate which is the greater of (i) the prime rate of the Credit Agent,
(ii) the secondary market rate for three-month certificates of deposit as
published in Federal Reserve Statistical Release H-15 (519), plus 1%, and
(iii) the Federal Funds rate, plus one-half of 1%. A commitment fee ranging
from 0.25% to 0.50% per annum of the unused daily amount of the total
commitment is payable quarterly.
 
  The term loan facility may be prepaid at any time by the Company. Such
facility is subject to quarterly amortization payments, beginning on September
30, 1998. Annual amortization payments will total $13.7 million, $34.2
million, $41.0 million, and $41.1 million in years 1998 through 2001,
respectively. In addition to scheduled amortization, the term loan facility is
subject to mandatory prepayment, without penalty or premium, to the extent of
(a) 75% of excess cash flow for any fiscal year, (b) a specified percentage,
based on leverage, from net proceeds derived from an equity issuance, (c) 100%
of net proceeds from a permitted debt issuance, and (d) 100% of net proceeds
from an asset sale in excess of $1.0 million, all as more fully set forth in
the Senior Credit Agreement.
 
  The Senior Credit Agreement contains a number of affirmative covenants,
including those relating to existence; business and properties; insurance;
taxes; recordkeeping and financial reporting; and notice of certain events, as
well as negative covenants, including: limitations on indebtedness; liens;
sale and lease-back transactions; investments, loans and advances; mergers,
consolidations and sales of assets; dividends and distributions; payment of
dividends by subsidiaries; capital expenditures; transactions with affiliates;
and changes in line of business. The Company is required to maintain specified
financial ratios with respect to leverage, senior debt, fixed charge coverage
and working capital and a minimum net worth.
 
  The Senior Credit Agreement contains customary events of default, including
covenant default, breach of representation and warranty, failure to pay
principal or interest or fees when due, cross-default to other indebtedness,
bankruptcy default, ERISA default, the occurrence of a change in control, the
guarantee agreement or any security document (as defined therein) ceasing to
be in full force and effect and any interest created by a security document
ceasing to be enforceable or ceasing to have the effect and priority purported
to be created thereby.
 
  Borrowings under the Senior Credit Agreement are secured on a senior basis
by mortgages on real property, liens on inventory and receivables and a pledge
of subsidiary stock, which represents substantially all of the Company's
assets. The Company's obligations under the Senior Credit Agreement are
jointly and severally guaranteed on a senior secured basis by the Company's
domestic subsidiaries.
 
  The Senior Subordinated Loan is being repaid from the proceeds of the Notes
offered hereby. See "Use of Proceeds."

                             DESCRIPTION OF NOTES
 
GENERAL
 
  The Notes are to be issued under an indenture, to be dated as of December
24, 1997 (the "Indenture") between the Company, the Guarantors and The Bank of
New York, as Trustee (the "Trustee"), a copy of which is available upon
request to the Company. The following summary of certain provisions of the
Indenture and the Notes does not purport to be complete and is subject to, and
is qualified in its entirety by reference to, all the provisions of the
Indenture (including the definitions of certain terms therein and those terms
made a part thereof by the Trust Indenture Act of 1939, as amended (the "Trust
Indenture Act")) and the Notes. Capitalized terms used herein and not
otherwise defined have the meanings set forth in "--Certain Definitions."
 
  Under certain circumstances, the Company will be able to designate current
or future Subsidiaries as Unrestricted Subsidiaries. Unrestricted Subsidiaries
will not be subject to the restrictive covenants set forth in the Indenture.
As of the date of the Indenture, all of the Company's Subsidiaries other than
Schein Pharmaceutical (Netherlands) B.V., Schein Pharmaceutical (Bermuda) Ltd.
and Schein Farmaceutica de Peru will be Restricted Subsidiaries.
 
TERMS OF THE NOTES
 
  The Notes will be limited to $100.0 million aggregate principal amount, and
will mature on December 15, 2004. Each Note will bear interest at the floating
rate described below payable quarterly in arrears on January 15, April 15,
July 15 and October 15, commencing on January 15, 1998, to holders of record
on the immediately preceding December 31, March 31, June 30 and September 30,
respectively.
 
  Interest on the Notes will accrue at a rate equal to the Applicable LIBOR
Rate and will be calculated on a formula basis by multiplying the principal
amount of the Notes then outstanding by the Applicable LIBOR Rate, and
multiplying such product by the LIBOR Fraction.
 
  The "Applicable LIBOR Rate" means, for each quarterly period during which
any Note is outstanding subsequent to the initial quarterly period, 300 basis
points over the rate determined by the Company (notice of such rate to be sent
to the Trustee by the Company on the date of determination thereof) equal to
the average (rounded upwards, if necessary, to the nearest 1/16 of 1%) of the
offered rates for deposits in U.S. dollars for a period of three months, as
set forth on the Reuters Screen LIBO Page as of 11:00 a.m., London time, on
the Interest Rate Determination Date for such quarterly period; provided,
however, that if only one such offered rate appears on the Reuters Screen LIBO
Page, the Applicable LIBOR Rate for such quarterly period will mean such
offered rate. If such rate is not available at 11:00 a.m., London time, on the
Interest Rate Determination Date for such quarterly period, then the
Applicable LIBOR Rate for such quarterly period will mean the arithmetic mean
(rounded upwards, if necessary, to the nearest 1/16 of 1%) of the interest
rates per annum at which deposits in amounts equal to US$1 million are offered
by the Reference Banks to leading banks in the London interbank market for a
period of three months as of 11:00 a.m., London time, on the Interest Rate
Determination Date for such quarterly period. If on any Interest Rate
Determination Date, at least two of the Reference Banks provide such offered
quotations, then the Applicable LIBOR Rate for such quarterly period will be
determined in accordance with the preceding sentence on the basis of the
offered quotations of those Reference Banks providing such quotations;
provided, however, that if fewer than two of the Reference Banks are so
quoting such interest rates as mentioned above, the Applicable LIBOR Rate for
such quarterly period shall be deemed to be the applicable LIBOR Rate for the
next preceding quarterly period and in the case of the quarterly period next
succeeding the initial quarterly period, the Applicable LIBOR Rate shall be
8.9375%. Notwithstanding the foregoing, the Applicable LIBOR Rate for the
initial quarterly period shall be 8.9375%.
 
  "Interest Rate Determination Date" means, with respect to each quarterly
period, the second London Banking Day prior to the first day of such quarterly
period.
 
  "LIBOR Fraction" means the actual number of days in the quarterly period
divided by 360; provided, however, that the number of days in each quarterly
period shall be calculated by including the first day of such quarterly period
and excluding the last.
 
                                      58
<PAGE>
 
  "London Banking Day" means any day in which dealings in U.S. dollars are
transacted or, with respect to any future date, are expected to be transacted
in the London interbank market.
 
  "quarterly period" means the period from and including a scheduled payment
date (or December 24, 1997, in the case of the initial quarterly period)
through the day next preceding the following scheduled interest payment date.
 
  "Reference Banks" means each of: Societe Generale, London Branch; The Chase
Manhattan Bank, London Branch; Deutsche Bank, London Branch; and Rabobank
Nederland, London Branch and any such replacement bank thereof as listed on
the Reuters Screen LIBO Page and their respective successors, and if any such
banks are not at the applicable time providing interest rates as contemplated
within the definition of the "Applicable LIBOR Rate," Reference Banks shall
mean the remaining bank or banks so providing such rates. In the event that
less than two of such banks are providing such rates, the Company shall use
reasonable efforts to appoint additional Reference Banks so that there are at
least two such banks providing such rates; provided, however, that such banks
appointed by the Company shall be London offices of leading banks engaged in
the London interbank market.
 
  "Reuters Screen LIBO Page" means the display designated as page "LIBO" on
the Reuter Monitor Money Rates Service (or such other page as may replace the
LIBO page on that service for the purpose of displaying London Interbank
Offered Rates of leading banks).
 
  If the date due for payment of interest on or principal of the Notes or the
date fixed for redemption of any Note shall not be a Business Day (as defined
herein), then payment of interest or principal need not be made on such date,
but may be made on the next succeeding Business Day with the same force and
effect as if made on the date of maturity or the date fixed for redemption,
and no interest shall accrue for the period after such date.
 
OPTIONAL REDEMPTION
 
  The Notes will be redeemable, at the option of the Company, in whole or in
part, at any time, upon not less than 30 nor more than 60 days' prior notice,
at 103.000% of the principal amount thereof, plus accrued and unpaid interest
thereon to, but excluding the date of redemption, if redeemed prior to January
15, 1998 and at the following redemption prices (expressed as a percentage of
principal amount), plus accrued and unpaid interest thereon to, but excluding,
the date of redemption, if redeemed during the 12-month period commencing on
January 15 of each year:

  If less than all of the Notes are to be redeemed, the Trustee shall select
the Notes or portions thereof to be redeemed pro rata, by lot or by any other
method the Trustee shall deem fair and reasonable, although no Note of $1,000
in original principal amount will be redeemed in part.
 
SINKING FUND
 
  The Notes will not be entitled to the benefit of any sinking fund or other
mandatory redemption obligation prior to maturity.
 
 
                                      59

GUARANTEES
 
  All of the Company's existing and future Restricted Subsidiaries (referred
to herein as the "Guarantors"), will unconditionally guarantee on a senior
unsecured basis the performance and punctual payment when due, whether at
maturity, by acceleration or otherwise, of all obligations of the Company
under the Indenture and the Notes. Each of the Guarantors has guaranteed the
Company's indebtedness under the Senior Credit Agreement on a senior secured
basis. The Subsidiary Guarantee of each Guarantor will be effectively
subordinated to the prior payment in full of all secured indebtedness of such
Guarantors, including secured indebtedness under the Senior Credit Agreement.
 
  Each Subsidiary Guarantee will be limited to an amount not to exceed the
maximum amount that can, after giving effect to all other contingent and fixed
liabilities of the applicable Guarantor, be guaranteed by such Guarantor,
without rendering such Subsidiary Guarantee voidable under applicable law
relating to fraudulent conveyance or fraudulent transfer or similar laws
affecting the rights of creditors generally. Each Guarantor will agree to pay,
in addition to the amount stated above, any and all costs and expenses
(including reasonable counsel fees and expenses) incurred by the Trustee or
any holder of a Note in enforcing any rights under the Subsidiary Guarantee
with respect to such Guarantor.
 
  Each Subsidiary Guarantee is a continuing guarantee and shall (a) remain in
full force and effect until payment in full of all the Notes, (b) be binding
upon the relevant Guarantor, and (c) enure to the benefit of and be
enforceable by the Trustee, the holders of Notes and their successors,
transferees and assigns.
 
RANKING
 
  The indebtedness evidenced by the Notes will be senior unsecured obligations
of the Company, will rank pari passu in right of payment with all existing and
future senior indebtedness of the Company and will rank senior in right of
payment to all existing and future indebtedness of the Company that is, by its
terms, expressly subordinated to the Notes. The Notes will also be effectively
subordinated to all existing and future indebtedness of any Subsidiary of the
Company that is not a Guarantor of the Notes.
 
  Holders of secured indebtedness of the Company, including the lenders under
the Senior Credit Agreement, will have claims with respect to the assets
constituting collateral for such indebtedness that are prior to the claims of
holders of the Notes. In the event of a default on the Notes, or a bankruptcy,
liquidation or reorganization of the Company, such assets will be available to
satisfy obligations with respect to the indebtedness secured thereby before
any payment therefrom could be made on the Notes. To the extent that the value
of such collateral is not sufficient to satisfy the indebtedness secured
thereby, amounts remaining outstanding on such indebtedness would be entitled
to share with the Notes and their claims with respect to any other assets of
the Company. As of September 27, 1997, as adjusted for the Offering, the
Company and its Restricted Subsidiaries would have had secured indebtedness of
approximately $160.6 million outstanding. The obligations of the Company and
the Guarantors under the Senior Credit Agreement are secured by substantially
all of the assets of the Company and the Guarantors. As of September 27, 1997,
as adjusted for the Offering, the Company would have had approximately $69.8
million of undrawn availability under the Senior Credit Agreement. The
Indenture will permit the Company and its Restricted Subsidiaries to incur
additional Indebtedness, including Secured Indebtedness, subject to certain
limitations.
 
CHANGE OF CONTROL
 
  If a Change of Control shall occur at any time, then each holder of Notes
shall have the right to require that the Company purchase such holder's Notes
in whole or in part in any integral multiple of $1,000, for a cash purchase
price (the "Change of Control Purchase Price") equal to 101% of the principal
amount of such Notes, plus accrued and unpaid interest, if any, on such Notes
to the date of purchase (the "Change of Control Purchase Date"), pursuant to
the offer described below (the "Change of Control Offer") and the other
procedures set forth in the Indenture.
 
 
                                      60
<PAGE>
 
  Within 15 days following any Change of Control, the Company shall notify the
Trustee thereof and give written notice of such Change of Control to each
holder of Notes by first-class mail, postage prepaid, at his address appearing
in the security register, stating, among other things, (i) that a Change of
Control has occurred and that such Holder has the right to require the Company
to purchase each Holder's Notes, in whole or in part, at the Change of Control
Purchase Price; (ii) the Change of Control Purchase Price and the Change of
Control Purchase Date which shall be a Business Day no earlier than 30 days
nor later than 60 days from the date such notice is mailed, or such later date
as is necessary to comply with requirements under the Exchange Act; (iii) that
any Note not tendered for purchase will continue to accrue interest; (iv)
that, unless the Company defaults in the payment of the Change of Control
Purchase Price, any Notes accepted for payment pursuant to the Change of
Control Offer shall cease to accrue interest after the Change of Control
Purchase Date; and (v) certain other procedures that a holder of Notes must
follow to accept a Change of Control Offer or to withdraw such acceptance.
 
  If a Change of Control Offer is made, there can be no assurance that the
Company will have available funds sufficient to pay the Change of Control
Purchase Price for all of the Notes that might be delivered by holders of the
Notes seeking to accept the Change of Control Offer. The Senior Credit
Agreement prohibits the purchase of the Notes by the Company prior to full
repayment of Indebtedness thereunder and, upon a Change of Control, all
amounts outstanding under the Senior Credit Agreement may become due and
payable. There can be no assurance that, in the event of a Change of Control,
the Company will be able to obtain the necessary consents from the lenders
under the Senior Credit Agreement to consummate a Change of Control Offer. The
failure of the Company to make or consummate the Change of Control Offer or
pay the Change of Control Purchase Price when due would result in an Event of
Default.
 
  The existence of a right of the holder of Notes to require the Company to
purchase such holder's Notes upon a Change of Control may deter a third party
from acquiring the Company in a transaction which constitutes a Change of
Control.
 
  The Company will comply with the applicable tender offer rules, including
Rule 14e-1 under the Exchange Act, and any other applicable securities laws or
regulations in connection with a Change of Control Offer.
 
  The Company will not, and will not permit any Subsidiary to, create or
permit to exist or become effective any restriction (other than restrictions
in effect on the Issue Date with respect to Indebtedness outstanding on the
Issue Date and refinancing thereof and customary default provisions) that
would materially impair the ability of the Company to make a Change of Control
Offer to purchase the Notes or, if such Change of Control Offer is made, to
pay for the Notes tendered for purchase.
 
CERTAIN COVENANTS
 
  The Indenture contains certain covenants including, among others, the
following:
 
  Limitation on Indebtedness. (a) The Company shall not, and shall not permit
any of its Restricted Subsidiaries to, incur any Indebtedness; provided,
however, that the Company may incur Indebtedness (including through the

Consolidated Coverage Ratio would be greater than (i) 2.50:1, if such
Indebtedness is incurred prior to the expiration of 24 months after the Issue
Date, and (ii) 3.00:1 if such Indebtedness is incurred on or subsequent to the
expiration of 24 months after the Issue Date.

Restricted Subsidiaries may incur Indebtedness to the extent set forth below:
(i) the incurrence by the Company of Indebtedness under the Senior Credit

credit being deemed to have a principal amount equal to the undrawn amount of
the letters of credit plus any unreimbursed drawings thereon) up to an
aggregate principal amount of $250.0 million outstanding at any one time, less
principal repayments of term loans and permanent commitment reductions with
respect to revolving loans and letters of credit under the Senior Credit
Agreement made after the Issuance Date with the Net Cash Proceeds of Asset
Dispositions, if any;
 
                                      61

represented by the Guarantees of the Notes and Guarantees of Indebtedness
incurred pursuant to clause (i) above; (vi) Indebtedness of the Company or any
Restricted Subsidiary under Interest Rate Agreements that are entered into by

Company or such Restricted Subsidiary incurred without violation of the
Indenture or with respect to customary commercial transactions of the Company
or such Restricted Subsidiary entered into in the ordinary course of business;
(vii) Indebtedness (including Capitalized Lease Obligations) incurred by the
Company or any Restricted Subsidiary to finance the purchase, lease or
improvement of property (real or personal) or equipment (whether through the
direct purchase of assets or the Capital Stock of any Person owning such

principal amount of all other Indebtedness then outstanding and incurred
pursuant to this clause (vii), does not exceed $25.0 million; (viii)
Indebtedness incurred by the Company or any Restricted Subsidiary constituting
reimbursement obligations with respect to letters of credit issued in the
ordinary course of business, including, without limitation, letters of credit
in respect of workers' compensation claims or self-insurance, or other
Indebtedness with respect to reimbursement type obligations regarding workers'
compensation claims; provided, that upon the drawing of such letters of credit
or the incurrence of such Indebtedness, such obligations are reimbursed within
30 days following such incurrence; (ix) Acquired Indebtedness; provided,
however, that such Indebtedness is not incurred in contemplation of such
acquisition or merger; and provided, further that the Company would have been
able to incur such Indebtedness at the time of the incurrence thereof pursuant
to clause (a) above, determined on a pro forma basis as if such transaction
had occurred at the beginning of such four-quarter period and such
Indebtedness and the operating results of such merged or acquired entity had
been included for all purposes in such pro forma calculation as if such entity
had been a Restricted Subsidiary at the beginning of such four-quarter period;
(x) obligations in respect of performance and surety bonds and completion
guarantees provided by the Company or any Restricted Subsidiary in the
ordinary course of business; (xi) additional indebtedness in an aggregate

Refinancing Indebtedness; provided, however, that (A) the principal amount of
such Refinancing Indebtedness shall not exceed the principal or accreted
amount (in the case of any Indebtedness issued with original issue discount,
as such) of Indebtedness so extended, refinanced, renewed, replaced,
substituted or refunded (the "Refinanced Indebtedness"), (B) the Refinancing
Indebtedness shall have a Weighted Average Life to Maturity of not less than
the stated maturity of the Refinanced Indebtedness and (C) the Refinancing
Indebtedness shall rank in right of payment relative to the Notes on terms at

documentation governing the Refinanced Indebtedness.
 
  (c) Notwithstanding any other provision of this covenant, neither the
Company nor any Restricted Subsidiary shall incur any Indebtedness (i)
pursuant to paragraph (b) above, if the proceeds thereof are used, directly or
indirectly, to repay, prepay, redeem, defease, retire, refund or refinance any
Subordinated Indebtedness unless such Indebtedness shall be subordinated to
the Notes to at least the same extent as such Subordinated Indebtedness or
(ii) pursuant to paragraph (a) or (b) if such Indebtedness is subordinate or
junior in ranking in any respect to any Senior Indebtedness unless such
Indebtedness is expressly subordinated in right of payment to such Senior
Indebtedness.
 
  (d) The Company shall not incur any Secured Indebtedness that is not Senior
Indebtedness.
 
  Limitation on Restricted Payments. (a) The Company shall not, and shall not
permit any Restricted Subsidiary to, directly or indirectly:
 
    (i) declare or pay any dividend on, or make any distribution to holders

  Capital Stock and other
 
                                      62

  principal payment, sinking fund or maturity, any Subordinated Indebtedness;
  or
 
    (iv) make any Investment in any Person, including, without limitation,
  any Unrestricted Subsidiary (other than a Permitted Investment)
 
(the foregoing actions described in clauses (i) through (iv) above being
hereinafter collectively referred to as "Restricted Payments") unless after
giving effect to the proposed Restricted Payment, (A) no Default or Event of
Default shall have occurred and be continuing and such Restricted Payment
shall not cause or constitute a Default or an Event of Default; (B)
immediately before and immediately after giving effect to such transaction on
a pro forma basis, the Company could incur $1.00 of additional Indebtedness
pursuant to paragraph (a) under "Limitation of Indebtedness"; and (C) the
aggregate amount of all such Restricted Payments (the amount of any such
Restricted Payment, if other than cash, to be determined in good faith by the
Board of Directors of the Company, whose determination shall be conclusive and

the Issue Date (including such Restricted Payment) does not exceed the sum of:
 
    (i) 50% of the aggregate cumulative Consolidated Net Income (or, if such
  aggregate cumulative Consolidated Net Income shall be a loss, minus 100% of
  such loss) of the Company accrued on a cumulative basis during the period
  (taken as one accounting period) from the fiscal quarter that first begins
  after the Issue Date to the end of the Company's most recently ended fiscal
  quarter for which internal financial statements are available at the time
  of such Restricted Payment;
 
    (ii) the aggregate Net Cash Proceeds received after the Issue Date by the
  Company from the issuance or sale (other than to any of its Subsidiaries)
  of its shares of Capital Stock (other than Disqualified Capital Stock) or

  paragraph (b) below);
 
    (iii) the aggregate Net Cash Proceeds received after the Issue Date by

  any options, warrants or rights to purchase shares of Capital Stock (other
  than Disqualified Capital Stock) of the Company;
 
    (iv) the aggregate Net Cash Proceeds received after the Issue Date by the
  Company from Indebtedness of the Company or Disqualified Capital Stock of
  the Company that has been converted into or exchanged for Capital Stock
  (other than Disqualified Capital Stock) of the Company or options, warrants
  or rights to acquire such Capital Stock, to the extent such Indebtedness of
  the Company or Disqualified Capital Stock of the Company was originally
  incurred or issued for cash, plus the aggregate Net Cash Proceeds received
  by the Company at the time of such conversion or exchange;
 
    (v) to the extent not included in Consolidated Net Income, the net
  reduction (received by the Company or any Restricted Subsidiary in cash) in

  Restricted Subsidiaries since the Issue Date, not to exceed, in the case of
  any Investments in any Person, the amount of Investments (other than
  Permitted Investments) made by the Company and the Restricted Subsidiaries
  in such Person since the Issue Date.

<PAGE>
 
  (b) Notwithstanding the foregoing, and in the case of clauses (v) and (vii)
below, so long as there is no Default or Event of Default continuing, the
foregoing provisions shall not prohibit the following actions:
 
    (i) the payment of any dividend within 60 days after the date of
  declaration thereof, if at such date of declaration such payment would be
  permitted by the provisions of paragraph (a) of this "Limitation on
  Restricted Payments" covenant (such payment being deemed to have been paid
  on such date of declaration for purposes of the calculation required by
  paragraph (a) of this "Limitation on Restricted Payments" covenant);
 
    (ii) the repurchase, redemption, or other acquisition or retirement of
  any shares of any class of Capital Stock of the Company or warrants,
  options or other rights to acquire such stock in exchange for, or out of
  the Net Cash Proceeds of a substantially concurrent issue and sale (other
  than to a Subsidiary) for cash of, any Capital Stock (other than
  Disqualified Capital Stock) of the Company or warrants, options or other
  rights to acquire such Capital Stock;
 
    (iii) any repurchase, redemption, defeasance, retirement, refinancing or
  acquisition for value or payment of principal of any Subordinated
  Indebtedness in exchange for, or out of the net proceeds of a substantially
  concurrent issuance and sale (other than to a Subsidiary) for cash of, any
  Capital Stock (other than Disqualified Capital Stock) of the Company or
  warrants, options or other rights to acquire such Capital Stock;
 
    (iv) the repurchase, redemption, defeasance, retirement or other
  acquisition for value or payment of principal of any Subordinated
  Indebtedness through the issuance of Refinancing Indebtedness;
 
    (v) Investments in Permitted Foreign Companies in a net aggregate amount
  not to exceed $10.0 million in any fiscal year, provided, however, that, to
  the extent the net aggregate amount of such Investments in any fiscal year
  is less than $10.0 million, 50% of such difference may be carried forward
  and added to the $10.0 million permitted amount for the subsequent fiscal
  year;
 
    (vi) Investments in Cheminor Drugs Limited and Dr. Reddy's Laboratories
  Limited having an aggregate fair market value, taken together with all
  other Investments made pursuant to this clause (vi) that are at the time
  outstanding, not to exceed $10.0 million; and
 
    (vii) Additional Investments (including, without limitation, Unrestricted
  Subsidiaries) having an aggregate fair market value, taken together with
  all other Investments made pursuant to this clause (vii) that are at the
  time outstanding, not to exceed $15.0 million at the time of such
  Investment (with the fair market value of each Investment being measured at
  the time made and without giving effect to subsequent changes in value).
 
The actions described in clauses (i) and (vii) of this paragraph (b) shall be
Restricted Payments that shall be permitted to be taken in accordance with
this paragraph (b) but shall reduce the amount that would otherwise be
available for Restricted Payments under clause (C) of paragraph (a) of this

consideration in, or to provide all or any portion of the funds or credit
support utilized to consummate, the transaction or series of related
transactions pursuant to which such Restricted Subsidiary became a Restricted
Subsidiary or was acquired by the Company) and outstanding on such date; (iii)
any encumbrance or restriction pursuant to an agreement effecting a
refinancing of Indebtedness incurred pursuant to an agreement referred to in
clause (i) or (ii) of this covenant or contained in any amendment to an
agreement referred to in clause (i) or (ii) of this covenant; provided,
however, that the encumbrances and restrictions with respect to such
Restricted Subsidiary contained in any such refinancing agreement or amendment
are no less favorable in any material respect to the holders of the Notes than
encumbrances and restrictions with respect to such Restricted Subsidiary
contained in such agreements; (iv) in the case of clause (c) above, any
encumbrance or restriction (A) that restricts in a customary manner the
subletting, assignment or transfer of any property or asset that is a lease,

on, any property or assets of the Company or any Restricted Subsidiary not
otherwise prohibited by the Indenture or (C) arising or agreed to in the
ordinary course of business, not relating to any Indebtedness, and that do
not, individually or in the aggregate, detract from the value of property or
assets of the Company or any Restricted Subsidiary in any manner material to
the Company or any Restricted Subsidiary; provided that, in each case, such
encumbrance or restriction relates to, and restricts dealings with, only the
property or asset that is the subject of such encumbrance or restriction; and
provided, further, that such encumbrance or restriction does not prohibit,
limit or otherwise restrict the making or payment of any dividend or other
distribution to the Company or any Restricted Subsidiary; (v) any restriction
with respect to a Restricted Subsidiary imposed pursuant to an agreement
entered into for the sale or disposition of all or substantially all the

or net worth imposed by customers under contracts entered into in the ordinary

  Limitation on Sales of Assets and Subsidiary Stock. (a) The Company shall
not, and shall not permit any Restricted Subsidiary to, make any Asset
Disposition unless (i) the Company or such Restricted Subsidiary receives
consideration (including by way of relief from, or by any other Person
assuming sole responsibility for, any liabilities, contingent or otherwise) at
the time of such Asset Disposition at least equal to the Fair Market Value of
the shares or assets that are the subject matter of such Asset Disposition,
(ii) at least 80% of the consideration therefor received by the Company or
such Restricted Subsidiary is in the form of cash; and (iii) an
 
                                      66
<PAGE>
 
amount equal to 100% of the Net Available Cash from such Asset Disposition is
applied by the Company (or such Restricted Subsidiary, as the case may be) (A)
first, to the extent the Company elects (or is required by the terms of the
Senior Credit Agreement), to prepay, repay or purchase such indebtedness
incurred under the Senior Credit Agreement within 180 days after the later of
the date of such Asset Disposition or the receipt of such Net Available Cash,
(B) second, to the extent of the balance of Net Available Cash after
application in accordance with clause (A), to the extent the Company elects,
to secure letter of credit obligations to the extent such related letters of
credit have not been drawn upon or returned undrawn; (C) third, to the extent
of the balance of Net Available Cash after application in accordance with
clauses (A) and (B), to the extent the Company or such Restricted Subsidiary
elects, within one year from the later of the date of such Asset Disposition
or the receipt of such Net Available Cash, to reinvest in, Additional Assets;
and (D) fourth, to the extent of the balance of such Net Available Cash after
application in accordance with clauses (A), (B) and (C), to make an offer to
purchase Notes pursuant and subject to the conditions of the Indenture to the

thereof plus accrued and unpaid interest to the purchase date; provided,
however, that, in connection with any prepayment, repayment or purchase of
Indebtedness pursuant to clause (A) or (B) above, the Company or such
Restricted Subsidiary shall retire such Indebtedness and shall cause the
related loan commitment (if any) to be permanently reduced in an amount equal
to the principal amount so prepaid, repaid or purchased. The Company shall not
be required to make an offer for Notes pursuant to this covenant if the Net
Available Cash available therefor (after application of the proceeds as
provided in clauses (A), (B) and (C)) is less than $15.0 million (which lesser
amount shall be carried forward for purposes of determining whether an offer
is required with respect to the Net Available Cash from any subsequent Asset
Disposition).
 
  For the purposes of clause (a)(ii) of this covenant, the following will be
deemed to be cash: (x) the assumption of Indebtedness (other than Disqualified
Capital Stock) of the Company or any Restricted Subsidiary and the release of
the Company or such Restricted Subsidiary from all liability on such
Indebtedness in connection with such Asset Disposition and (y) securities
received by the Company or any Restricted Subsidiary of the Company from the
transferee that are promptly converted by the Company or such Restricted
Subsidiary into cash.
 
  (b) In the event of an Asset Disposition that requires the purchase of Notes
pursuant to clause (a)(iii)(D) of this covenant, the Company will be required
to purchase Notes tendered pursuant to an offer by the Company for the Notes
at a purchase price of 100% of their principal amount plus accrued interest to
the purchase date in accordance with the procedures (including prorating in
the event of oversubscription) set forth in the Indenture.
 
  (c) The Company shall comply with the applicable tender offer rules,
including Rule 14e-1 under the Exchange Act, and any other securities laws or
regulations in connection with the repurchase of Notes pursuant to this
covenant.
 
  Limitation on Affiliate Transactions. The Company shall not, and shall not
permit any Restricted Subsidiary to, directly or indirectly, enter into or
conduct any transaction (including the purchase, sale, lease or exchange of
any property or the rendering of any service) with any Affiliate of the
Company (an "Affiliate Transaction") unless: (i) the terms of such Affiliate
Transaction are no less favorable to the Company or such Restricted
Subsidiary, as the case may be, than those that could be obtained at the time
of such transaction in arm's-length dealings with a Person who is not an
Affiliate; (ii) in the event such Affiliate Transaction involves an aggregate
amount in excess of $1.0 million (unless such Affiliate Transaction
constitutes an agreement with Bayer A.G. or its Affiliate relating to an
Investment by the Company and an Investment by Bayer A.G. or its Affiliate in
a Permitted Foreign Company in which case the requirements of this clause
shall be applicable only if the amount being invested by the Company exceeds
$10.0 million), the terms of such transaction have been approved by a majority
of the members of the Board of Directors of the Company and by a majority of
the disinterested members of such Board, if any (and such majority or
majorities, as the case may be, determines that such Affiliate Transaction
satisfies the criteria in (i) above) and (iii) in the event such Affiliate
Transaction involves an aggregate amount in excess of $15.0 million (unless
such Affiliate Transaction constitutes an agreement with Bayer A.G. or its
Affiliate relating to an Investment by the Company and an Investment by Bayer
A.G. or its Affiliate in a Permitted Foreign Company in which case the
requirements of this clause shall be
 
                                      67
<PAGE>
 
applicable only if the amount being invested by the Company exceeds $25.0
million), the Company has received a written opinion from an independent
investment banking firm of nationally recognized standing that such Affiliate
Transaction is fair to the Company or such Restricted Subsidiary, as the case
may be, from a financial point of view.
 
  The provisions of the foregoing paragraph will not prohibit (i) any
Restricted Payment permitted to be paid or made pursuant to the covenant
described under "Limitation on Restricted Payments," (ii) the performance of

contemplated by, the General Shareholders Agreement dated September 30, 1994,
and the Continuing Shareholders Agreement dated September 30, 1994, in each
cased as in effect on the date of this Indenture or (viii) any agreement
entered into in the ordinary course or business between the Company and a
Person who constitutes an Affiliate solely by reason of such Person being an

by the Company, upon or following the termination of such Person's employment
or directorship with the Company, of shares of Capital Stock of the Company
owned by such Person.
 
  Limitation on Sale of Capital Stock of Restricted Subsidiaries. The Company
(i) shall not, and shall not permit any Restricted Subsidiary to, transfer,
convey, sell or otherwise dispose of any Capital Stock of any Restricted
Subsidiary to any Person (other than to the Company or a Restricted
Subsidiary) and (ii) shall not permit any Restricted Subsidiary to issue any
of its Capital Stock to any Person other than to the Company or a Restricted
Subsidiary; provided, however, that the foregoing shall not prohibit the
transfer, conveyance, sale or other disposition of all the Capital Stock of a
Restricted Subsidiary if the Net Cash Proceeds from such transfer, conveyance,
sale or other disposition are applied in accordance with the covenant
described above under "Limitation on Sales of Assets and Subsidiary Stock";
and, provided, further, that this covenant shall not prohibit the transfer,
conveyance, sale or other disposition of less than all of the Capital Stock of
a Restricted Subsidiary or the issuance by any Restricted Subsidiary of any of
its Capital Stock to any Person as long as (A) the Net Cash Proceeds from such
transfer, conveyance, sale or other disposition or issuance are applied in
accordance with the "Limitation on Sales of Assets and Subsidiary Stock"
covenant, (B) immediately after giving effect to such transaction, no Event of
Default shall have occurred and be continuing, (C) immediately after giving
pro forma effect to such transaction, as if such transaction had occurred at

Consolidated Coverage Ratio test as set forth in paragraph (a) of the
"Limitation on Indebtedness" covenant and (D) immediately after giving effect
to such transaction, such Restricted Subsidiary remains a Restricted
Subsidiary of the Company.

that the Company shall not, and shall not permit any of its Restricted
Subsidiaries to, enter into any sale and leaseback transaction; provided that

(iii) the transfer of assets in such sale and leaseback transaction is
permitted by, and the Company applies the net proceeds of such transaction in

MERGER AND CONSOLIDATION
 
  The Company shall not consolidate with or merge with or into, or convey,
transfer or lease all or substantially all its assets to, any Person, unless:
(i) the resulting, surviving or transferee Person (the "Successor Company")
shall be a Person organized and existing under the laws of the United States
of America, any state thereof or the District of Columbia and the Successor
Company (if not the Company) shall expressly assume, by an indenture
supplemental to the Indenture, executed and delivered to the Trustee, in form
reasonably satisfactory to the Trustee, all the obligations of the Company
under the Notes and the Indenture; (ii) immediately after giving effect to
such transaction (and treating any Indebtedness which becomes an obligation of
the Successor Company or any Restricted Subsidiary as a result of such
transaction as having been incurred by such Successor Company or such
Restricted Subsidiary at the time of such transaction), no Event of Default
shall have occurred and be continuing; (iii) immediately after giving pro
forma effect to such transaction, as if such transaction had occurred at the
beginning of the applicable four-quarter period, the Successor Company would
be permitted to incur at least $1.00 of additional Indebtedness pursuant to
the Consolidated Coverage Ratio test set forth in paragraph (a) of the
"Limitation on Indebtedness" covenant; and (iv) the Company shall have
delivered to the Trustee an Officers' Certificate and an Opinion of Counsel,
each stating that such consolidation, merger or transfer and each supplemental
indenture (if any) comply with the Indenture.
 
  The Successor Company shall be the successor of the Company and shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company under the Indenture, but the predecessor Company in the case of a
conveyance, transfer or lease shall not be released from the obligation to pay
the principal of and interest on the Notes.
 
EVENTS OF DEFAULT
 
  An Event of Default is defined in the Indenture as (i) a default in any
payment of interest on any Note when due and payable, continued for 30 days,
(ii) a default in the payment of principal of any Note when due and payable at
its Stated Maturity, upon optional redemption, upon required repurchase, upon
declaration or otherwise, (iii) the failure by the Company to comply with its
obligations under "--Merger and Consolidation," (iv) the failure by the
Company to comply for 30 days after notice with any of its obligations under
"--Change of Control" or under the covenants described under "Certain
Covenants" above (in each case, other than a failure to purchase Notes which
shall constitute an Event of Default under clause (ii) above), (v) the failure
by the Company to comply for 30 days after notice with its other covenants and
agreements contained in the Indenture or the Notes, (vi) Indebtedness of the
Company or any Restricted Subsidiary is not paid within any applicable grace
period after final maturity or is accelerated by the holders thereof because
of a default and the total amount of such Indebtedness unpaid or accelerated
exceeds $10.0 million or its foreign currency equivalent at the time (the
"cross acceleration provision"), (vii) certain events of bankruptcy,
insolvency or reorganization of the Company or a Material Subsidiary (the
"bankruptcy provisions"), (viii) any judgment or decree for the payment of
money in excess of $10.0 million or its foreign currency equivalent at the
time (to the extent not covered by insurance) is entered against the Company
or a Material Subsidiary and is not discharged and either (A) an enforcement
proceeding has been commenced by any creditor upon such judgment or decree and
is not promptly stayed or (B) such judgment or decree shall remain
undischarged or unstayed for a period of 60 days following the entry of such
judgment or decree (the "judgment default provision") or (ix) the failure of
any Subsidiary Guarantee of the Notes to be in full force and effect (except
as contemplated by the terms thereof) or the denial or disaffirmation by any
Guarantor of its obligations under the Indenture or any Subsidiary Guarantee
of the Notes if such failure is not cured, or such denial or disaffirmation is
not rescinded or revoked, within 10 days. However, a default under clauses
(iv) and (v) will not constitute an Event of Default until the Trustee or the
holders of at least 25% in principal amount of the outstanding Notes notify
the Company in writing of the default and the Company does not cure such
default within the time specified in clauses (iv) and (v) hereof after receipt
of such notice.
 
  If an Event of Default (other than an Event of Default specified in clause
(vii) above with respect to the Company) occurs and is continuing, the
Trustee, by written notice to the Company, or the holders of at least
 
                                      69
<PAGE>
 
25% in outstanding principal amount of the Notes, by written notice to the
Company and the Trustee, may declare the principal of, and accrued and unpaid
interest on, all the Notes to be due and payable. Upon such a declaration,
such principal and interest shall be due and payable (i) if no Indebtedness is
outstanding under the Senior Credit Agreement, immediately, and (ii) if any
Indebtedness is outstanding under the Senior Credit Agreement, upon the first
to occur of (x) the acceleration of any such Indebtedness or (y) the fifth
Business Day after receipt by the Company and the Credit Agent of such written
notice of acceleration. If an Event of Default specified in clause (vii) above
occurs and is continuing, the principal of, and accrued and unpaid interest
on, all the Notes shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any
holders. Under certain circumstances, the holders of a majority in principal
amount of the outstanding Notes may rescind any such acceleration with respect
to the Notes and its consequences.
 
  Subject to the provisions of the Indenture relating to the duties of the
Trustee, if an Event of Default occurs and is continuing, the Trustee will be
under no obligation to exercise any trust or power under the Indenture at the
request, order or direction of any of the holders unless such holders have
offered to the Trustee indemnification satisfactory to it in its sole
discretion against all losses and expenses. Except to enforce the right of any
holder to receive payment of the principal of and interest on the Notes held
by such holder on or after the respective due dates expressed in the Notes, no
holder may pursue any remedy with respect to the Indenture or the Notes unless
(i) such holder has previously given the Trustee notice that an Event of
Default is continuing, (ii) holders of at least 25% in outstanding principal
amount of the outstanding Notes have requested the Trustee to pursue the
remedy, (iii) such holders have offered the Trustee reasonable security or
indemnity against any loss, liability or expense, (iv) the Trustee has not
complied with such request within 60 days after the receipt of the request and
the offer of security or indemnity, and (v) the holders of a majority in
principal amount of the outstanding Notes have not given the Trustee a
direction that is inconsistent with such request within such 60 day period.
Subject to certain restrictions, the holders of a majority in outstanding
principal amount of the Notes may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee
may refuse to follow any direction that conflicts with law or the Indenture
or, subject to the provisions of the Indenture relating to the duties of the
Trustee, that the Trustee determines is unduly prejudicial to the rights of
other holders (it being understood that, subject to the provisions of the
Indenture relating to the duties of the Trustee, the Trustee shall have no
duty to ascertain whether or not such actions or forbearances are unduly
prejudicial to such holders) or would subject the Trustee to personal
liability; provided, however, that the Trustee may take any other action
deemed proper by the Trustee that is not inconsistent with such direction.
Prior to taking or refraining from taking any such action hereunder, the
Trustee shall be entitled to indemnification satisfactory to it in its sole
discretion against all losses and expenses caused by its taking or refraining
from taking such action.
 
  The Indenture provides that if a Default or Event of Default occurs and is
continuing and if a Trust Officer has actual knowledge thereof, the Trustee
shall mail to each holder notice of the Default or Event of Default within 90
days after it occurs. Except in the case of a Default or Event of Default in
payment of principal of, or interest on, any Note (including payments pursuant
to the optional redemption or required repurchase provisions of such Note, if
any), the Trustee may withhold the notice if and so long as its board of
directors, the Executive Committee of its board of directors or a committee of
its Trust Officers in good faith determines that withholding the notice is in
the interests of the holders of the Notes. In addition, the Company is
required to deliver to the Trustee: (i) within 5 days after the occurrence
thereof, written notice in the form of an Officers' Certificate of any Event
of Default under clause (vi) above and any event which with the giving of
notice or the lapse of time would become an Event of Default under clause
(iv), (v) or (viii), its status and what action the Company is taking or
proposes to take with respect thereto and (ii) within 120 days after the end
of each fiscal year, written notice in the form of an Officers' Certificate
indicating whether the officers signing such Officers' Certificate had actual
knowledge of any Default that occurred during such previous fiscal year.
 
AMENDMENTS AND WAIVERS
 
  Subject to certain exceptions, the Indenture may be amended with the consent
of the holders of a majority in principal amount of the Notes then outstanding
and any past default or compliance with any provisions may
 
                                      70
<PAGE>
 
be waived with the consent of the holders of a majority in principal amount of
the Notes then outstanding. However, without the consent of each holder of an
outstanding Note affected, no amendment may, among other things, (i) reduce
the amount of Notes whose holders must consent to an amendment, (ii) reduce
the rate of or extend the time for payment of interest on any Note, (iii)
reduce the principal of or extend the Stated Maturity of any Note, (iv) reduce
the premium payable upon the redemption or repurchase of any Note or change
the time at which any Note may or shall be redeemed or repurchased in
accordance with the Indenture, (v) make any Note payable in money other than
that stated in the Note, (vi) modify or affect in any manner adverse to the
holders of the Notes, the terms and conditions of the obligation of the
Company for the due and punctual payment of the principal of or interest on
the Notes or (vii) make any change in the amendment provisions which require
each holder's consent or in the waiver provisions.
 
  Without the consent of any holder, the Company and the Trustee may amend the
Indenture to cure any ambiguity, omission, defect or inconsistency, to provide
for the assumption by a successor corporation of the obligations of the
Company under the Indenture, to provide for uncertificated Notes in addition
to or in place of certificated Notes (provided that the uncertificated Notes
are issued in registered form for purposes of Section 163(f) of the Code, or
in a manner such that the uncertificated Notes are described in Section
163(f)(2)(B) of the Code), to add Guarantees with respect to the Notes, to
secure the Notes, to add to the covenants of the Company for the benefit of
the holders of the Notes or to surrender any right or power conferred upon the
Company, to make any change that does not adversely affect the rights of any
holder or to comply with any requirement of the Commission in connection with
the qualification of the Indenture under the Trust Indenture Act.
 
  The consent of the holders is not necessary under the Indenture to approve
the particular form of any proposed amendment. It is sufficient if such
consent approves the substance of the proposed amendment.
 
  After an amendment under the Indenture becomes effective, the Company is
required to mail to the holders a notice briefly describing such amendment.
However, the failure to give such notice to all the holders, or any defect
therein, will not impair or affect the validity of the amendment.
 
TRANSFER AND EXCHANGE
 
  A holder of Notes may transfer or exchange Notes in accordance with the
Indenture. The Company or the Trustee may require any Note presented for
registration of transfer, exchange, redemption or payment to be duly endorsed
by, or be accompanied by a written instrument or instruments of transfer in
form satisfactory to the Company and the Trustee duly executed by, the holder
or his attorney duly authorized in writing. The Company may require payment of
a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any exchange or registration of transfer of Notes.
No service charge may be imposed for any such transaction. The Trustee may not
be required to exchange or register a transfer of (i) any Notes for a period
of 15 days next preceding the first mailing of notice of redemption of Notes
to be redeemed or (ii) any Notes selected, called or being called for
redemption except, in the case of any Note where public notice has been given
that such Note is to be redeemed in part, the portion thereof not so to be
redeemed. The Notes will be issued in registered form and the registered
holder of a Note will be treated as the owner of such Note for all purposes.
 
DEFEASANCE
 
  Subject to certain conditions and to the survival of certain of the
Company's obligations under the Indenture, the Company at any time may
terminate (i) all its obligations under the Notes and the Indenture and all
obligations of the Subsidiary Guarantors under the Subsidiary Guarantee and
the Indenture ("legal defeasance option") or (ii) its obligations under
certain covenants described under "Certain Covenants," the operation of the
cross acceleration provision and the judgement default provision described
under "Events of Default" above and the limitations contained in clauses (iii)
and (iv) under "--Merger and Consolidation" above ("covenant defeasance"). The
Senior Credit Agreement prohibits the legal defeasance and covenant defeasance
of the Notes as long as there are obligations outstanding under the Senior
Credit Agreement. However, no deposit of funds shall be effective to terminate
the obligations of the Company under the Notes or the Indenture prior to 123
days following any such deposit.
 
                                      71
<PAGE>
 
  The Company may exercise its legal defeasance option notwithstanding its
prior exercise of its covenant defeasance option. If the Company exercises its
legal defeasance option, payment of the Notes may not be accelerated because
of an Event of Default. If the Company exercises its covenant defeasance
option, payment of the Notes may not be accelerated because of an Event of
Default specified in clause (iv), (v), (vi), (viii) or (ix) under "Events of
Default" above or because of the failure of the Company to comply with clause
(iii) or (iv) under "--Merger and Consolidation" above.
 
  In order to exercise either defeasance option, the Company must irrevocably
deposit in trust (the "defeasance trust") with the Trustee money or U.S.
Government Obligations for the payment of principal of and interest on the
Notes to maturity or redemption, as the case may be, and must comply with
certain other conditions, including delivery to the Trustee of an Opinion of
Counsel to the effect that holders of the Notes will not recognize income,
gain or loss for federal income tax purposes as a result of such defeasance
and will be subject to federal income tax on the same amounts, in the same
manner and at the same times as would have been the case if such defeasance
had not occurred (and, in the case of legal defeasance only, such Opinion of
Counsel must be based on a ruling of the Internal Revenue Service or other
change in applicable federal income tax law).

  The Bank of New York is to be the Trustee under the Indenture and has been
appointed by the Company as Registrar and Paying Agent with regard to the
Notes. The Bank of New York is a lender under the Senior Credit Agreement.
 
GOVERNING LAW
 
  The Indenture provides that it and the Notes will be governed by, and
construed in accordance with, the laws of the State of New York without giving

BOOK-ENTRY; DELIVERY AND FORM
 
  Except as set forth below, the Notes will initially be issued in the form of
one or more registered notes in global form without coupons (each a "Global
Note"). Each Global Note will be deposited on the date of the closing of the
sale of the Notes (the "Closing Date") with, or on behalf of, The Depository
Trust Company (the "Depository") and registered in the name of Cede & Co., as
nominee of the Depository, or will remain in the custody of the Trustee
pursuant to the FAST Balance Certificate Agreement between the Depository and
the Trustee. Interests in the Global Note will be available for purchase only
by "qualified institutional buyers," as defined in Rule 144A under the
Securities Act ("QIBs").
 
  Notes that were (i) originally issued to or transferred to institutional
"accredited investors," as defined in Rule 501(a) (1), (3) or (7) under the
Securities Act ("Institutional Accredited Investors"), who are not QIBs or to
any other persons who are not QIBs or (ii) issued as described below under
"Certificated Securities," will be issued in registered definitive form
without coupons (the "Certificated Securities"). Upon the transfer to a QIB of
Certificated Securities, such Certificated Securities may, unless the Global
Note has previously been exchanged for Certificated Securities, be exchanged
for an interest in the Global Note representing the principal amount of Notes
being transferred. For a description of the restrictions on the transfer of
Certificated Securities, see "Transfer Restrictions."
 
  The Depository has advised the Company that it is (i) a limited purpose
trust company organized under the laws of the State of New York, (ii) a member
of the Federal Reserve System, (iii) a "clearing corporation"
 
                                      81
<PAGE>
 
within the meaning of the Uniform Commercial Code, as amended, and (iv) a
"Clearing Agency" registered pursuant to Section 17A of the Exchange Act. The
Depository was created to hold securities for its participants (collectively,
the "Participants") and facilitates the clearance and settlement of securities
transactions between Participants through electronic book-entry changes to the
accounts of its Participants, thereby eliminating the need for physical
transfer and delivery of certificates. The Depository's Participants include
securities brokers and dealers (including the Initial Purchaser), banks and
trust companies, clearing corporations and certain other organizations. Access
to the Depository's system is also available to other entities such as banks,
brokers, dealers and trust companies (collectively, the "Indirect
Participants") that clear through or maintain a custodial relationship with a
Participant, either directly or indirectly. QIBs may elect to hold Notes
purchased by them through the Depository. QIBs who are not Participants may
beneficially own securities held by or on behalf of the Depository only
through Participants or Indirect Participants. Persons that are not QIBs may
not hold Notes through the Depository.
 
  The Company expects that pursuant to procedures established by the
Depository (i) upon deposit of the Global Notes, the Depository will credit
the accounts of Participants designated by the Initial Purchaser with an
interest in the Global Note and (ii) ownership of the Notes will be shown on,
and the transfer of ownership thereof will be effected only through, records
maintained by the Depository (with respect to the interest of Participants),
the Participants and the Indirect Participants. The laws of some states
require that certain persons take physical delivery in definitive form of
securities that they own and that security interests in negotiable instruments
can only be perfected by delivery of certificates representing the
instruments. Consequently, the ability to transfer Notes or to pledge the
Notes as collateral will be limited to such extent. For certain other
restrictions on the transferability of the Notes, see "Transfer Restrictions."
 
  So long as the Depository or its nominee is the registered owner of the
Global Note, the Depository or such nominee, as the case may be, will be
considered the sole owner or Holder of the Notes represented by the Global
Note for all purposes under the Indenture. Except as provided below, owners of
beneficial interests in a Global Note will not be entitled to have Notes
represented by such Global Note registered in their names, will not receive or
be entitled to receive physical delivery of Certificated Securities, and will
not be considered the owners or holders thereof under the Indenture for any
purpose, including with respect to giving of any directions, instruction or
approval to the Trustee thereunder. As a result, the ability of a person
having a beneficial interest in Notes represented by a Global Note to pledge
such interest to persons or entities that do not participate in the
Depository's system or to otherwise take action with respect to such interest,
may be affected by the lack of a physical certificate evidencing such
interest.
 
  Accordingly, each QIB owning a beneficial interest in a Global Note must
rely on the procedures of the Depository and, if such QIB is not a Participant
or an Indirect Participant, on the procedures of the Participant through which
such QIB owns its interest, to exercise any rights of a Holder under the
Indenture or such Global Note. The Company understands that under existing
industry practice, in the event the Company requests any action of holders or
a QIB that is an owner of a beneficial interest in a Global Note desires to
take any action that the Depository, as the Holder of such Global Note, is
entitled to take, the Depository would authorize the Participants to take such
action and the Participant would authorize QIBs owning through such
Participants to take such action or would otherwise act upon the instruction
of such QIBs. Neither the Company nor the Trustee will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of Notes by the Depository, or for maintaining, supervising or
reviewing any records of the Depository relating to such Notes.
 
  Payments with respect to the principal of, premium, if any, and interest on
any Notes represented by a Global Note registered in the name of the
Depository or its nominee on the applicable record date will be payable by the
Paying Agent to or at the direction of the Depository or its nominee in its
capacity as the registered Holder of the Global Note representing such Notes
under the Indenture. Under the terms of the Indenture, the Company and the
Trustee may treat the persons in whose names the Notes, including the Global
Notes, are registered as the owners thereof for the purpose of receiving such
payment and for any and all other purposes whatsoever. Consequently, neither
the Company nor the Trustee nor the Paying Agent (if other than the Trustee)
has or will have
 
                                      82
<PAGE>
 
any responsibility or liability for the payment of such amounts to beneficial
owners of Notes (including principal, premium, if any, and interest), or to
immediately credit the accounts of the relevant Participants with such
payment, in amounts proportionate to their respective holdings in principal
amount of beneficial interest in the Global Note as shown on the records of
the Depository. Payments by the Participants and the Indirect Participants to
the beneficial owners of Notes will be governed by standing instructions and
customary practice and will be the responsibility of the Participants or the
Indirect Participants.
 
CERTIFICATED SECURITIES
 
  If (i) the Company notifies the Trustee in writing that the Depository is no
longer willing or able to act as a depository and the Company is unable to
locate a qualified successor within 90 days, (ii) the Company, at its option,
notifies the Trustee in writing that it elects to cause the issuance of Notes
in definitive form under the Indenture or (iii) upon the occurrence of certain
other events, then, upon surrender by the Depository of its Global Notes,
Certificated Securities will be issued to each person that the Depository
identifies as the beneficial owner of the Notes represented by the Global
Note. Upon any such issuance, the Trustee is required to register such
Certificated Securities in the name of such person or persons (or the nominee
of any thereof), and cause the same to be delivered thereto.
 
  Neither the Company nor the Trustee shall be liable for any delay by the
Depository or any Participant or Indirect Participant in identifying the
beneficial owners of the related Notes and each such person may conclusively
rely on, and shall be protected in relying on, instructions from the
Depository for all purposes (including with respect to the registration and
delivery, and the respective principal amounts, of the Notes to be issued).

                  EXCHANGE AND REGISTRATION RIGHTS AGREEMENT
 
  The Company and the Initial Purchaser will enter into an exchange and
registration rights agreement (the "Exchange and Registration Rights
Agreement") prior to or concurrently with the issuance of the Notes offered
hereby. Pursuant to the Exchange and Registration Rights Agreement, the
Company will agree (i) to file with the Commission on or prior to 45 days
after the date of issuance of the Notes (the "Issue Date") a registration
statement (the "Exchange Offer Registration Statement"), with respect to an
offer to exchange the Notes (the "Registered Exchange Offer") for senior notes
of the Company with terms identical in all material respects to those of the
Notes ("Exchange Notes") and (ii) to use commercially reasonable efforts to
cause the Exchange Offer Registration Statement to be declared effective under
the Securities Act within the earlier of (A) 90 days after the Issue Date or
(B) 30 days after the consummation of the initial public offering of the
Company's Common Stock. Upon the effectiveness of the Exchange Offer
Registration Statement, the Company will commence the Registered Exchange
Offer to holders of the Notes who are not prohibited by any law or policy of
the Commission from participating in the Registered Exchange Offer. The
Company will keep the Exchange Offer open for not less than 30 days (or
longer, if required by applicable law) after the date notice of the Exchange
Offer is mailed to the holders of the Notes. If (i) any change in law or
applicable interpretations of the staff of the Commission does not permit the
Company to effect the Registered Exchange Offer as contemplated thereby or
(ii) the Initial Purchaser, as a holder of Notes, (A) is not eligible to
participate in the Exchange Offer or (B) participates in the Exchange Offer
and does not receive freely transferable Exchange Notes in exchange for
tendered Notes, the Company will file with the Commission and use commercially
reasonable efforts to cause to be declared effective on or prior to the latter
of (x) 120 days after the Issue Date or (y) 45 days after the publication of
the change in law or interpretation, a registration statement on an
appropriate form under the Securities Act relating to the offer and sale of
the Notes by the holders thereof, from time to time, in accordance with such
registration statement and Rule 415 under the Securities Act (the "Shelf
Registration Statement").
 
  The Company will use commercially reasonable efforts to have the Exchange
Offer Registration Statement or, if applicable, a Shelf Registration Statement
(each a "Registration Statement") declared effective by the Commission as
promptly as practicable after the filing thereof. Unless the Registered
Exchange Offer would not be permitted by a policy of the Commission, the
Company will commence the Registered Exchange Offer and will use its
reasonable best efforts to consummate the Registered Exchange Offer as
promptly as practicable, but in any event on or prior to 150 days after the
Issue Date. If applicable, the Company will use commercially reasonable best
efforts to keep the Shelf Registration Statement effective for the earlier of
three years from the Issue Date or such shorter period that will terminate
when all the Notes covered by the Shelf Registration Statement have been sold,
subject to certain exceptions, including suspending the effectiveness thereof
as required by law or for certain valid business reasons.
 
  Although the Company intends to file the registration statements described
above, as required, there can be no assurance that such registration
statements will be filed, or, if filed, that they will become effective. In
the event (to the extent applicable) that (i) (A) the Exchange Offer
Registration Statement is not filed on or prior to the 45th day following the
Issue Date, (B) the Exchange Offer Registration Statement is not declared
effective within the earlier of (x) 90 days after the Issue Date or (y) 30
days after the consummation of the initial public offering of the Company's
Common Stock or (C) the Registered Exchange Offer is not consummated on or
prior to the 150th day following the Issue Date or (ii) the Shelf Registration
Statement is not declared effective on or prior to the later of (x) the 120th
day after the Issue Date and (y) the 45th day after the publication of the
change in law or interpretation referred to in the second preceding paragraph,
the interest rate borne by the Notes shall be increased by one-half of one
percent per annum following, in the case of clause (i)(A) such 45-day period,
in the case of clauses (i)(B) such 90- or 30-day period, as the case may be,
or in the case of clause (i)(C), such 150-day period, or, in the case of
clause (ii), such 45- or 120-day period, as applicable. The aggregate amount
of such increase from the original interest rate pursuant to these provisions
will in no event exceed one-half of one percent per annum. Such increase will
cease to be effective on the date of filing of the Exchange Offer Registration
Statement, effectiveness of the Exchange Offer Registration Statement,
consummation of the Registered Exchange Offer or the effectiveness of a Shelf
Registration Statement, as the case may be.
 
                                      84
<PAGE>
 
  Any amounts of additional interest due pursuant to the preceding paragraph
will be payable in cash, on the same original interest payment dates as the
Notes. The amount of additional interest will be determined by multiplying the
applicable additional interest rate by the principal amount of the affected
Notes of such holders, multiplied by a fraction, the numerator of which is the
number of days such additional interest rate was applicable during such
period, and the denominator of which is 360.
 
  The Exchange and Registration Rights Agreement will also provide that the
Company (i) shall cause the Exchange Offer Registration Statement to remain
continuously effective for a period of at least 20 Business Days (or longer if
required by applicable law) from its effective date, and shall supplement or
amend the prospectus contained therein to the extent necessary to permit such
prospectus (as supplemented or amended) to be delivered by broker-dealers in
connection with any resale of any such Exchange Notes and (ii) shall pay all
expenses incident to the Exchange Offer and will indemnify certain holders of
the Notes (including any broker-dealer) against certain liabilities, including
liabilities under the Securities Act. A broker-dealer that delivers such a
prospectus to purchasers in connection with such resales will be subject to
certain of the civil liability provisions under the Securities Act, and will
be bound by the provisions of the Exchange and Registration Rights Agreement
(including certain indemnification rights and obligations).
 
  Each holder of the Notes that wishes to exchange such Notes for Exchange
Notes in the Exchange Offer will be required to make certain representations,
including representations that (i) any Exchange Notes to be received by it
will be acquired in the ordinary course of its business, (ii) it has no
arrangement with any person to participate in the distribution of the Exchange
Notes and (iii) it is not an "affiliate," as defined in Rule 405 of the
Securities Act, of the Company or if it is an affiliate, it will comply with
the registration and prospectus delivery requirements of the Securities Act to
the extent applicable.
 
  If a holder is not a broker-dealer, it will be required to represent that it
is not engaged in, and does not intend to engage in, the distribution of the
Exchange Notes. If a holder is a broker-dealer that will receive Exchange
Notes for its own account in exchange for Notes that were acquired as a result
of market making activities or other trading activities, it will be required
to acknowledge that it will deliver a prospectus in connection with any resale
of such Exchange Notes.
 
  Holders of the Notes will be required to make certain representations to the
Company in order to participate in the Exchange Offer, and will be required to
deliver information to be used in connection with the Shelf Registration
Statement in order to have their Notes included in the Shelf Registration
Statement. A holder who sells Notes pursuant to the Shelf Registration
Statement generally will be required to be named as a selling security holder
in the related prospectus and to deliver a prospectus to purchasers, will be
subject to certain of the civil liability provisions under the Securities Act
in connection with such sales and will be bound by the provisions of the
Exchange and Registration Rights Agreement which are applicable to such a
holder (including certain indemnification obligations).
 
  A holder whose Notes are included in a Registration Statement will be
required to agree not to effect any public sale or distribution of the issue
being registered or a similar security of the Company or any securities
convertible into or exchangeable or exercisable for such securities, including
a sale pursuant to Rule 144 under the Securities Act, during the 14 days prior
to, and during the 90-day period beginning on, the effective date of such
Registration Statement (except as part of such registration), if and to the
extent requested by the Company in the case of a non-underwritten public
offering or if and to the extent requested by the managing Underwriter or
Underwriters in the case of an underwritten public offering.
 
  Notwithstanding any other provision set forth above, the Company may delay
the filing of any Registration Statement for up to 90 days if (i) the Company
would, in the opinion of its counsel, be required to disclose in such
Registration Statement information not otherwise then required by law to be
publicly disclosed and (ii) in the judgment of the Board of Directors of the
Company, there is a reasonable likelihood that such disclosure, or any other
action to be taken in connection with any Registration Statement, would
adversely affect any existing or prospective material business situation,
transaction, or negotiation or otherwise materially and adversely affect the
Company.

  Unless the Company is then subject to Section 13 or 15(d) of the Exchange
Act, the Company will continue to provide to holders of the Notes and to
prospective purchasers of the Notes, for so long as the Notes are outstanding,
the information required by Rule 144A under the Securities Act ("Rule 144A"),
as such Rule may be amended, or any similar rule or regulation adopted by the
Commission. The Company will provide a copy of the Exchange and Registration
Rights Agreement to prospective purchasers of Notes identified to the Company
by the Initial Purchaser upon request.
 
  The foregoing description of the Exchange and Registration Rights Agreement
is a summary only, does not purport to be complete and is qualified in its
entirety by reference to all provisions of the Exchange and Registration
Rights Agreement.

                             TRANSFER RESTRICTIONS
 
  Each purchaser of Notes from the Initial Purchaser, by its acceptance
thereof, will be deemed to have acknowledged, represented to and agreed with
the Company and the Initial Purchaser as follows:
 
    1. It understands and acknowledges that the Notes have not been
  registered under the Securities Act or any other applicable securities law,
  and that the Notes are being offered for resale in transactions not
  requiring registration under the Securities Act or any other securities
  laws, including sales pursuant to Rule 144A and, unless so registered, may
  not be offered, sold or otherwise transferred except in compliance with the
  registration requirements of the Securities Act or any other applicable
  securities laws, pursuant to any exemption therefrom or in a transaction
  not subject thereto and in each case in compliance with the conditions for
  transfer set forth in paragraph (4) below.
 
    2. It is not an "affiliate" (as defined in Rule 144 under the Securities
  Act) of the Company or acting on behalf of the Company and is either:
 
      (a) a "Qualified Institutional Buyer" as defined in Rule 144A
    ("QIB"), and is aware that any sale of the Notes to it will be made in
    reliance on Rule 144A and such acquisition will be for its own account
    or for the account of another QIB; or
 
      (b) an "Institutional Accredited Investor" within the meaning of Rule
    501(a)(1), (2), (3) and (7) under the Securities Act or, if the Notes
    are to be purchased for one or more accounts ("investor accounts") for
    which it is acting as fiduciary or agent, each such account is an
    Institutional Accredited Investor on a like basis. It is aware that the
    minimum principal amount of Notes that may be purchased by an
    Institutional Accredited Investor (including each investor account) is
    $250,000. In the normal course of its business, it invests in or
    purchases securities similar to the Notes and it has such knowledge and
    experience in financial and business matters that it is capable of
    evaluating the merits and risks of purchasing the Notes. It is aware
    that it (or any investor account) may be required to bear the economic
    risk of an investment in the Notes of an indefinite period of time and
    it (or such account) is able to bear such risk for an indefinite
    period.
 
    3. It acknowledges that neither the Company, the Initial Purchaser nor
  any person representing the Company or the Initial Purchaser has made any
  representation to it with respect to the Company or the Offering, other
  than the information contained in this Offering Memorandum, which has been
  delivered to it and upon which it is relying in making its investment
  decision with respect to the Notes. It has had access to such financial and
  other information concerning the Company and the Notes as it has deemed
  necessary in connection with its decision to purchase the Notes, including
  an opportunity to ask questions of and request information from the Company
  and the Initial Purchaser.
 
    4. It is purchasing the Notes for its own account or for one or more
  investor accounts for which it is acting as a fiduciary or agent, in each
  case not with a view to, or for offer or sale in connection with, any
  distribution thereof in violation of the Securities Act, subject to any
  requirement of law that the disposition of its property or the property of
  such investor account or accounts be at all times within its or their
  control and subject to its or their ability to resell such Notes pursuant
  to Rule 144A or any exemption from registration available under the
  Securities Act. It agrees on its own behalf and on behalf of any investor
  account for which it is purchasing the Notes, and each subsequent holder of
  the Notes by its acceptance thereof will agree, to offer, sell or otherwise
  transfer such Notes prior to the date which is two years after the later of
  the date of original issue and the last date that the Company or any
  affiliate of the Company was the owner of such Notes (or any predecessor
  thereto) (the "Resale Restriction Termination Date") only (i) to the
  Company, (ii) pursuant to a registration statement that has been declared
  effective under the Securities Act, (iii) for so long as the Notes are
  eligible for resale pursuant to Rule 144A, to a person it reasonably
  believes is a QIB that purchases for its own account or for the account of
  a QIB to whom notice is given that the transfer is being made in reliance
  on Rule 144A, (iv) pursuant to offers and sales that occur outside the
  United States within the meaning of Regulation S under the Securities Act,
  (v) to an Institutional Accredited Investor (as defined in Rule 501(a)(1),
  (2), (3) and (7) under the Securities Act) that is
 
                                      87
<PAGE>
 
  purchasing for its own account or for the account of such an Institutional
  Accredited Investor, in each case in a minimum principal amount of the
  Notes of $250,000 or (vi) pursuant to any other available exemption from
  the registration requirements of the Securities Act, subject in each of the
  foregoing cases to any requirement of law that the disposition of its
  property or the property of such investor account or accounts be at all
  times within its or their control. The foregoing restrictions on resale
  will not apply subsequent to the Resale Restriction Termination Date. If
  any resale or other transfer of the Notes is proposed to be made pursuant
  to clause (v) above prior to the Resale Restriction Termination Date, the
  transferor shall deliver a letter from the transferee substantially in the
  form of Annex A hereto to the Company and the Trustee, which shall provide,
  among other things, that the transferee is an Institutional Accredited
  Investor that is acquiring such Notes not for distribution in violation of
  the Securities Act, and for the transferee's representations to the same
  effect as set forth in paragraph 5 below, with respect to the transferee's
  purchase and holding of such Notes. Each purchaser acknowledges that the
  Company and the Trustee reserve the right prior to any offer, sale or other
  transfer prior to the Resale Restriction Termination Date of the Notes
  pursuant to clauses (iv), (v) and (vi) above to require the delivery of an
  opinion of counsel, certifications and/or other information satisfactory to
  the Company and the Trustee. Each purchaser acknowledges that each Note
  will contain a legend substantially to the following effect.

  THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF AGREES TO OFFER, SELL
OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE DATE (THE "RESALE

ORIGINAL ISSUE DATE HEREOF AND THE LAST DATE ON WHICH THE ISSUER OR ANY
AFFILIATE OF THE ISSUER WAS THE OWNER OF THIS SECURITY (OR ANY PREDECESSOR OF
SUCH SECURITY), ONLY (A) TO THE ISSUER, (B) PURSUANT TO A REGISTRATION

    5. Each purchaser, by its purchase of the Notes, shall be deemed to have
  represented that (i) if it is an insurance company, the funds to be used to
  purchase the Notes by it constitute (A) assets of an insurance company
  general account maintained by it and the acquisition and holding of each
  such Note by such account is exempt under United States Department of Labor
  Prohibited Transaction Class Exemption ("PTCE") 95-60 or (B) assets of an
  insurance company pooled separate account and the acquisition and holding
  of each such Note by such account is exempt under PTCE 90-1, and (ii) no
  part of the funds to be used to purchase the Notes to be purchased by it
  constitute assets of any plan or employee benefit plan such that the use of
  such assets constitutes a non-exempt prohibited transaction under ERISA or
  the Code. The representation is based upon the purchaser's determination
  that a statutory or administrative exemption is applicable or that the
  Company and its Affiliates are not parties in interest or disqualified
  persons with respect to the purchaser or holder plan or employee benefit
  plan. As used in this paragraph, the terms "employee benefit plan" and
  "party in interest" shall have the meanings assigned to such terms in
  Section 3 of ERISA, the term "Affiliate" shall have the meaning assigned to
  such term in Section 407(d)(7) of ERISA and the terms "disqualified person"
  and "plan" shall have the meanings assigned to such terms in Section 4975
  of the Code. If any resale or other transfer of the Notes is proposed to be
  made pursuant to clause (v) of paragraph 4 above prior to the Resale
  Restriction Termination Date, the transferor shall deliver a letter from
  the transferee to the Company and the Trustee, which shall contain a
  representation of the transferee with respect to the transferee's purchase
  and holding of the Notes, substantially as set forth in paragraph 3 of
  Annex A hereto.
 
    6. It acknowledges that the Company, the Initial Purchaser and others
  will rely upon the truth and accuracy of the foregoing acknowledgments,
  representations and agreements and agrees that, if any of the
  acknowledgments, representations or warranties deemed to have been made by
  it by its purchase of Notes are no longer accurate, it shall promptly
  notify the Company and the Initial Purchaser. If it is acquiring any Notes
  as a fiduciary or agent for one or more investor accounts, it represents
  that it has sole investment discretion with respect to each such account
  and that it has full power to make the foregoing acknowledgments,
  representations and agreements on behalf of each such account.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  The following summary describes the principal U.S. federal income tax
consequences resulting from the ownership and disposition of the Notes by U.S.
Holders (as defined below) that are initial purchasers of Notes. Except where
noted, it deals only with Notes held as capital assets and does not deal with
special situations, such as those of dealers in securities or currencies,
financial institutions, tax-exempt entities, life insurance companies, persons
holding Notes as part of a hedging, conversion or constructive sale
transaction or a straddle or holders whose "functional currency" is not the
U.S. dollar. Furthermore, the discussion below is based upon provisions of the
Internal Revenue Code of 1986, as amended (the "Code"), and regulations,
rulings and judicial decisions thereunder as of the date hereof, and such
authorities may be repealed, revoked or modified so as to result in United
States federal income tax consequences different from those discussed below.
Persons considering the purchase, ownership or disposition of Notes should
consult their own tax advisors concerning the United States federal income tax
consequences in light of their particular situations as well as any
consequences arising under the laws of any other taxing jurisdiction.
 
  As used herein, a "U.S. Holder" is (i) a citizen or resident of the United
States, (ii) a corporation or partnership created or organized in or under the
laws of the United States or a State thereof (including the District of
Columbia), (iii) an estate the income of which is subject to United States
federal income taxation regardless of source or (iv) a trust if (a) a U.S.
court is able to exercise primary supervision over the trust's administration
and (b) one or more U.S. persons have the authority to control all of the
trust's substantial decisions. The term also includes certain former citizens
of the United States.
 
ORIGINAL ISSUE DISCOUNT
 
  For purposes of the Code, each Note will be deemed to have been issued with
original issue discount ("OID") equal to the difference between the Note's
stated redemption price at maturity (i.e., the sum of all payments to be made
on the Note other than stated interest payments) and its "issue price." U.S.
Holders of Notes should be aware that they generally must include OID in gross
income in advance of the receipt of cash attributable to that income. A U.S.
Holder must include in gross income the sum of the daily portions of OID which
accrue under a constant yield method with respect to such instrument for each
day during the accrual period (or portion of the accrual period) in which such
U.S. Holder held such Notes, regardless of the U.S. Holder's method of
accounting for tax purposes. The amount of OID which accrues in an accrual
period is an amount equal to the excess (if any) of (i) the product of the
Note's "adjusted issue price" at the beginning of such accrual period and its
yield to maturity (determined on the basis of compounding at the end of each
accrual period and appropriately adjusted to take into account the length of
the particular accrual period) over (ii) the sum of the stated interest
payments, if any, allocable to the accrual period. The daily portion of OID is
determined by allocating to each day in any accrual period a ratable portion
of OID allocable to the accrual period. The "adjusted issue price" of a Note
at the beginning of any accrual period is the sum of the issue price of such
Note plus the OID allocable to all prior accrual periods reduced by payments
on the Note other than stated interest. An "accrual period" may be of any
length and the accrual periods may even vary in length over the term of the
debt instrument, provided that each accrual period is no longer than one year
and each scheduled payment of principal or interest occurs at the end of an
accrual period. Under these rules, U.S. Holders generally will have to include
in income increasingly greater amounts of OID in successive accrual periods.
Generally, a U.S. Holder's tax basis in the debt instrument will be increased
by the amount of OID that is included in such U.S. Holder's income pursuant to
the foregoing rules through the day preceding the day of disposition and will
be decreased by the amount of any cash payments received (other than a payment
of stated interest).
 
  Special rules apply to the calculation of OID in the case of a debt
instrument whose issuer has an intention to call the instrument before
maturity. The Company intends to take the position that under applicable
Treasury Regulations (the "OID Regulations") the special rules will not apply
to the Notes.
 
  Under the OID Regulations, a U.S. Holder may elect to treat all interest and
discount on a Note (including stated interest and OID) as income by using the
constant yield method applicable to OID, subject to certain limitations and
exceptions. Such an election must be made for the taxable year in which the
U.S. Holder acquires the Note and may not be revoked unless approved by the
IRS.
 
                                      90
<PAGE>
 
SALE, EXCHANGE OR REDEMPTION
 
  A U.S. Holder's adjusted tax basis in a Note will, in general, be the U.S.
Holder's cost for the Note increased by OID. The sale, exchange or redemption
of a Note generally will be a taxable event for federal income tax purposes. A
U.S. Holder generally will recognize gain or loss on the sale, exchange or
redemption of a Note in an amount equal to the difference between (i) the
amount of cash plus the fair market value of any property received upon such
sale, exchange or redemption (other than the amount of such consideration
received in respect of accrued but unpaid interest which will be taxable as
such) and (ii) the U.S. Holder's adjusted tax basis in such Note. Such gain or
loss will be capital gain or loss. Under recently enacted legislation, capital
gains of individuals derived in respect of capital assets held for more than
one year are eligible for reduced rates of taxation which may vary depending
upon the holding period of such capital assets. Prospective investors should
consult their own tax advisors with respect to the tax consequences of the new
legislation. The deductibility of capital losses is subject to limitations.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
  Certain noncorporate U.S. Holders may be subject to backup withholding at a
rate of 31% on payments made on a Note. Backup withholding will apply only if
a U.S. Holder (i) fails to furnish its taxpayer identification number ("TIN")
which, in the case of an individual, would be his or her social security
number, (ii) furnishes an incorrect TIN, (iii) is notified by the IRS that it
has failed to properly report payments of interest and dividends or (iv) under
certain circumstances, fails to certify, under penalties of perjury, that it
has furnished a correct TIN. Amounts withheld under the backup withholding
rules are not an additional tax and may be refunded, or credited against the
U.S. Holder's United States federal income tax liability, provided that the
required information is furnished to the IRS. The Company will furnish
annually to the IRS and to certain record U.S. Holders of the Notes
information relating to the amount of OID, if any, accruing during the
calendar year. The Company's determination of OID generally is binding on a
U.S. Holder for U.S. federal income tax purposes but is not binding on the
IRS, and there can be no assurance that the IRS will not challenge such
determination.

                             PLAN OF DISTRIBUTION
 
  Subject to the terms and conditions set forth in the Purchase Agreement (the
"Purchase Agreement") by and among the Company, the Guarantors and Societe
Generale Securities Corporation (the "Initial Purchaser"), the Company agrees
to sell to the Initial Purchaser, and the Initial Purchaser agrees to
purchase, $100.0 million principal amount of the Notes.
 
  The Purchase Agreement provides that the obligations of the Initial
Purchaser thereunder are subject to certain conditions precedent, and that the
Initial Purchaser is committed to take and pay for $100.0 million aggregate
principal amount of Notes, if any are taken. The Company will separately pay a
commission to the Initial Purchaser of 3.000% of the principal amount of the
Notes purchased. The Initial Purchaser proposes to offer the Notes at the
applicable initial offering price set forth on the cover page of this Offering
Memorandum (the "Note Offering Price"). After the Notes are released for sale,
the Note Offering Price and other selling terms may from time to time be
varied by the Initial Purchaser.
 
  The Company and the Restricted Subsidiaries have agreed in the Purchase
Agreement to indemnify the Initial Purchaser against certain liabilities under
the Securities Act, and to contribute to payments that the Initial Purchaser
may be required to make in respect thereof.
 
  The Initial Purchaser proposes to offer the Notes for resale in transactions
not requiring registration under the Securities Act or applicable state
securities laws, including sales pursuant to Rule 144A. The Initial Purchaser
proposes to offer the Notes for resale initially at the offering price set
forth on the cover page of this Offering Memorandum. After the initial
offering, the offering price and other selling terms may be changed at any
time without notice. The Initial Purchaser will not offer or sell the Notes
except to persons it reasonably believes to be QIBs or Institutional
Accredited Investors. Each purchaser of the Notes offered hereby in making its
purchase will, by its purchase, be deemed to have made certain
acknowledgements, representations, warranties and agreements as set forth
under "Transfer Restrictions" and, in the case of purchasers that are
Institutional Accredited Investors, will be required to complete and deliver
to the Initial Purchaser a purchaser questionnaire prior to acceptance of any
order.
 
  The Notes have been designated eligible for trading in the PORTAL market.
The Notes have not been registered under the Securities Act and may not be
offered or sold except as set forth above. The Initial Purchaser has advised
the Company that the Initial Purchaser currently intends to make a market in
the Notes; however, it is not obligated to do so and any market making may be
discontinued by the Initial Purchaser at any time without notice. In addition,
such market making activity may be limited during the Exchange Offer described
below and the pendency of the effectiveness of the applicable Registration
Statement. Accordingly, no assurance can be given as to the liquidity of or
the trading market for the Notes.
 
  In connection with the Offering, the Initial Purchaser may engage in
overallotment, stabilizing transactions and syndicate covering transactions.
Overallotment involves sales in excess of the offering size, which creates a
short position for the Initial Purchaser. Stabilizing transactions involve
bids to purchase the Notes in the open market for the purpose of pegging,
fixing or maintaining the price of the Notes. Syndicate covering transactions
involve purchases of the Notes in the open market after the distribution has
been completed in order to cover short positions. Such stabilizing
transactions and syndicate covering transactions may cause the price of the
Notes to be higher than it would otherwise be in the absence of such
transactions. Such activities, if commenced, may be discontinued at any time.
 
  The Company has covenanted with the Initial Purchaser (i) that within 45
days after the Issue Date, the Company will file with the Commission an
Exchange Offer Registration Statement under the Securities Act with respect to
an issue of Exchange Notes and (ii) to use commercially reasonable efforts to
cause such Exchange Offer Registration Statement to be declared effective
under the Securities Act within the earlier of (A) 90 days after the Issue
Date or (B) 30 days after the effectiveness of the registration statement
filed in connection with an initial public offering of the Company's Common
Stock. Upon effectiveness of that Exchange Offer Registration
 
                                      92
<PAGE>
 
Statement, the Company will offer to the holders of the Notes the opportunity
to exchange their Notes for a like principal amount of Exchange Notes, which
Exchange Notes will be issued without the legend described above under
"Transfer Restrictions" and (generally other than by an affiliate of the
Company) may be reoffered and resold by the holder without restrictions or
limitations under the Securities Act. The Company has also covenanted with the
Initial Purchaser to consummate the Registered Exchange Offer within 150 days
after the Issue Date. Additionally, the Company has covenanted that if any
change in law or applicable interpretations of the staff of the Commission
does not permit the Company to effect the Registered Exchange Offer, the
Company will file with the Commission and use commercially reasonable efforts
to cause to be declared effective a Shelf Registration Statement with respect
to the resale of Notes and to keep the Shelf Registration Statement effective
until three years from the Issue Date or such shorter period that will
terminate when all the Notes covered by the Shelf Registration Statement have
been sold. The Company shall cause such Shelf Registration Statement to be
declared effective on or prior to the latter of (x) the 120th day after the
Issue Date or (y) the 45th day after the publication of the change in law or
interpretation. See "Exchange and Registration Rights Agreement."
 
  It is expected that delivery of the Notes will be made against payment
therefor on or about the date specified in the last paragraph of the cover
page of this Offering Memorandum, which will be the third business day
following the date hereof.
 
  Societe Generale, an affiliate of Societe Generale Securities Corporation,
is the lender under the Senior Subordinated Loan Agreement, dated as of

Corporation a fee of $750,000 for financial advisory services rendered to the
Company in connection with the amendment of the Senior Subordinated Loan
Agreement.

                             AVAILABLE INFORMATION
 
  Immediately following the Offering, the Company will not be subject to the
periodic reporting and other informational requirements of the Exchange Act.
Until its acquisition by the Company in 1995, Marsam was subject to the
periodic reporting and other informational requirements of the Exchange Act,
and therefore, its Forms 10-K and 10-Q for periods prior to its acquisition
are available from the Commission. The Company has agreed that,
notwithstanding that it may not be subject to the reporting requirements of
Sections 13 or 15(d) of the Exchange Act, for so long as any Notes are
outstanding, the Company will furnish to the Trustee and the holders of the
Notes (i) within 45 days after the end of each of the first three fiscal
quarters of each fiscal year and 90 days of the end of each fiscal year all
quarterly and annual financial information, as the case may be, that would be
required to be contained in a filing with the Commission on Forms 10-Q and 10-
K if the Company were required to file any such Forms, including a
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and, with respect to the annual information only, a report thereon
by the Company's certified independent accountants and (ii) all current
reports that would be required to be filed with the Commission on Form 8-K if
the Company were required to file such reports. In addition, whether or not
required by the rules and regulations of the Commission, the Company will file
a copy of all such information and reports with the Commission for public
availability (unless the Commission will not accept such a filing) and make
such information available to securities analysts and prospective investors
upon request. Furthermore, for so long as any of the Notes remain outstanding,
the Company has agreed to make available to any prospective purchaser of the
Notes or beneficial owner of the Notes, in connection with any sale thereof,
the information required by Rule 144(d)(4) under the Securities Act.

              REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
Board of Directors
Schein Pharmaceutical, Inc.
 
  We have audited the accompanying consolidated balance sheets of Schein
Pharmaceutical, Inc. and subsidiaries as of December 30, 1995 and December 28,
1996, and the related consolidated statements of operations, stockholders'
equity and cash flows for each of the three years in the period ended December
28, 1996. These consolidated financial statements are the responsibility of
the management of Schein Pharmaceutical, Inc. and subsidiaries. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the consolidated financial
statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the
consolidated financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as
well as evaluating the overall consolidated financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of Schein Pharmaceutical, Inc. and subsidiaries as of December 30, 1995 and
December 28, 1996, and the consolidated results of their operations and their
cash flows for each of the three years in the period ended December 28, 1996
in conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 (INFORMATION AS OF SEPTEMBER 1997 AND FOR THE NINE-MONTHS ENDED SEPTEMBER 28,
                   1996 AND SEPTEMBER 27, 1997 IS UNAUDITED)
 
NOTE 1--SUMMARY OF ACCOUNTING POLICIES
 
  The Company and Principles of Consolidation
 
  Schein Pharmaceutical, Inc. and its subsidiaries (the "Company") are engaged
in developing, manufacturing, marketing and distributing generic
pharmaceutical products. The Company sells to drug store chains, independent
retail pharmacies, managed care organizations, hospitals and other
institutions, both through drug wholesalers and directly, primarily in the
U.S.
 
  In 1995, Schein Holdings, Inc. ("SHI"), the former parent holding
corporation of Schein Pharmaceutical, Inc., was merged into Schein
Pharmaceutical, Inc. The Company was the only asset held by SHI, and, as such,
the accompanying financial statements reflect the operations of the Company
for the periods reported.
 
  The consolidated financial statements include the accounts of the Company
and its wholly-owned and majority-owned subsidiaries. Investments in
unconsolidated affiliated companies are accounted for on the equity method.
All material intercompany accounts and transactions have been eliminated in
consolidation.
 
  Certain prior year amounts have been reclassified to conform to the current
year's presentation.
 
  Fiscal Year
 
  The Company reports its operations on a 52-53 week basis ending on the last
Saturday of December. Of the years presented in these statements, 1994
includes 53 weeks.
 
  Interim Financial Information
 
  The financial statements as of September 27, 1997 and for the nine months
ended September 28, 1996 and September 27, 1997 are unaudited but reflect all
adjustments (consisting only of normal recurring adjustments) which are, in
the opinion of management, necessary for a fair presentation of financial
position and results of operations. Operating results for the nine months
ended September 27, 1997 are not necessarily indicative of the results that
may be expected for the fiscal year ending December 27, 1997.
 
  Cash Equivalents
 
  The Company considers all highly liquid debt instruments and other short-
term investments with an initial maturity date of three months or less from
purchase date to be cash equivalents.
 
  Inventories
 
  Inventories are valued at the lower of cost or market. Cost is determined by
the first-in, first-out method.
 
  Property, Plant, Equipment, Depreciation and Amortization
 
  Property, plant and equipment are stated at cost. Depreciation and
amortization are computed primarily under the straight-line method over
estimated useful lives. Amortization of capital leases is computed using the
straight-line method over the lease term.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 (INFORMATION AS OF SEPTEMBER 1997 AND FOR THE NINE-MONTHS ENDED SEPTEMBER 28,
                   1996 AND SEPTEMBER 27, 1997 IS UNAUDITED)
 
 
  Long-Lived Assets
 
  The Company adopted in 1995 Statement of Financial Accounting Standards
("SFAS") No. 121, Accounting for Impairment of Long-Lived Assets and for Long-
Lived Assets to be Disposed of. In accordance with SFAS No. 121, the carrying
values of long-lived assets are periodically reviewed by the Company and
impairments would be recognized if the expected future operating non-
discounted cash flows derived from an asset were less than its carrying value.
 
  Deferred Loan Fees
 
  Costs incurred in connection with entering into or amending debt agreements
are capitalized to Other Assets and amortized to interest expense using the
effective interest method over the lives of the related debt.
 
  Goodwill and Product Rights, Licenses and Regulatory Approvals
 
  Goodwill is being amortized over 25 years on a straight-line basis. Product
rights, licenses and regulatory approvals are amortized on a straight-line
basis over the expected profitable and useful lives of the underlying products
and manufacturing facilities, generally for periods ranging from 10 to 20
years.
 
  Investments in Marketable Securities
 
  The Company's available-for-sale marketable securities are carried at fair
market value and are included in Other Assets in the accompanying balance
sheets. Unrealized gains are recorded directly to stockholders' equity, net of
applicable income taxes. The Company uses the specific identification method
of determining cost in calculating related gains and losses. The Company does
not own held-to-maturity or trading securities.
 
  Estimated Fair Value of Financial Instruments
 
  The carrying amounts of financial instruments, including cash and cash
equivalents, accounts receivable, accounts payable and accrued liabilities,
approximate fair value because of the current nature of these instruments. The
carrying amounts reported for revolving credit and long-term debt approximate
fair value because the interest rates on these instruments are subject to
changes with market interest rates.
 
  Revenue Recognition
 
  Revenues are recognized when products are shipped. Provisions for estimated
sales allowances, returns and losses are accrued at the time revenues are
recognized.
 
  Research and Development Expenditures
 
  Expenditures for research and development are expensed as incurred.
 
  Taxes on Income
 
  The Company accounts for income taxes in accordance with SFAS No. 109,
Accounting for Income Taxes. Under this standard, deferred taxes on income are
provided for those items for which the reporting period and methods for income
tax purposes differ from those used for financial statement purposes using the
asset and liability method. Deferred income taxes are recognized for the tax
consequences of "temporary differences" by applying enacted statutory rates
applicable to future years to differences between the financial statement
carrying amounts and the tax bases of existing assets and liabilities.

                   1996 AND SEPTEMBER 27, 1997 IS UNAUDITED)
 
  Foreign Currency Translations
 
  Assets and liabilities of international affiliates are translated at current
exchange rates and related translation adjustments are reported as a component
of stockholders' equity. Income statement accounts are translated at the
average rates during the period.
 
  Concentration of Credit Risk
 
  The Company is potentially subject to a concentration of credit risk with
respect to its trade receivables, the majority of which are due from
wholesalers, drug store chains, and distributors. The Company performs ongoing
credit evaluations of its customers and generally does not require collateral.
The Company maintains sufficient allowances and insurance to cover potential
or anticipated losses for uncollectible accounts.
 
  Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires the Company to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Effect of Recently Issued Accounting Standards
 
  In June 1997, the Financial Accounting Standards Board issued two new
disclosure standards.
 
  Statement of Financial Accounting Standards No. 130 ("SFAS No. 130"),
Reporting Comprehensive Income, establishes standards for reporting and
display of comprehensive income, its components and accumulated balances.
Comprehensive income is defined to include all changes in equity except those
resulting from investments by owners and distributions to owners. Among other
disclosures, SFAS No. 130 requires that all items that are required to be
recognized under current accounting standards as components of comprehensive
income be reported in a financial statement that is displayed with the same
prominence as other financial statements.
 
  Statement of Accounting Standards No. 131 ("SFAS No. 131"), Disclosures
about Segments of an Enterprise and Related Information, which supersedes SFAS
No. 14, Financial Reporting for Segments of a Business Enterprise, establishes
standards for the way that public enterprises report information about
operating segments in annual financial statements and requires reporting of
selected information about operating segments in interim financial statements
issued to the public. It also establishes standards for disclosures regarding
products and services, geographic areas and major customers. SFAS No. 131
defines operating segments as components of an enterprise about which separate
financial information is available that is evaluated regularly by the chief
operating decision maker in deciding how to allocate resources and in
asserting performance.
 
  Both of these new standards are effective for financial statements for
periods beginning after December 15, 1997 and require comparative information
for earlier years to be restated. Results of operations and financial position
will be unaffected by implementation of these new standards. The Company has
not determined whether either of these two standards will have a material
impact on its financial statement disclosure.

NOTE 2--RESTRUCTURING
 
  As discussed in Note 1, SHI, the former parent corporation of the Company,
was merged into the Company in 1995. Prior to September 1994, in addition to
its ownership of the Company, SHI was engaged in the manufacture, distribution
and sale of dental, medical and veterinary products ("Henry Schein"). In 1992,
SHI initiated a series of transactions as part of a corporate reorganization
plan (the "Restructuring") to split off Henry Schein to certain SHI
stockholders and realign the ownership interests of SHI. In September 1994,
the series of transactions culminated when the capital stock of Henry Schein
was distributed to individuals (and certain trusts established by them) who
were holders (or beneficiaries of trusts and estates which were holders) of
SHI's common stock prior to September 30, 1994 ("Historical SHI
Stockholders").
 
  The transactions related to the Restructuring were initiated in December
1992 when SHI contributed the net assets of Henry Schein to a newly formed
company which was owned by SHI. Schein Pharmaceutical, Inc. and Henry Schein
both issued common stock to their respective chief executive officers
("CEOs"), which were forfeitable if certain conditions were not satisfied, and
paid cash bonuses to reimburse them for the personal income tax effects of the
stock issuance and reimbursements. SHI subsequently issued shares of its
common stock in exchange for the Schein Pharmaceutical, Inc. stock issuance
and these shares were reflected in the 1992 financial statements.
 
  The Restructuring continued in 1993, when Historical SHI Stockholders and
Company management agreed to a transaction whereby an investor would purchase
a portion of SHI's outstanding shares from Historical SHI Stockholders and
seek future strategic alliances (the "Minority Investor Transaction").
Following governmental regulatory review and Surrogate Court approval, the
closing occurred on September 30, 1994. The Restructuring transactions
recorded in 1994 are as follows:
 
    (i) SHI distributed the shares of Henry Schein to the Historical SHI
  Stockholders.
 
    (ii) SHI issued 6,945 shares of its common stock in exchange for the
  minority interest-redeemable stock in Schein Pharmaceutical, Inc.'s
  subsidiaries. The $13.2 million fair value of the shares issued exceeded
  the minority interest previously recorded by $7.3 million. Of this amount,
  $5.5 million was classified as special compensation expense in 1994 (for
  Schein Pharmaceutical, Inc. employees) and $1.8 million was recorded as a
  distribution by the Company to Henry Schein (for the CEO of Henry Schein).
 
    (iii) As a result of the Minority Investor Transaction described above,
  the shares of common stock issued to the CEOs of the Company and Henry
  Schein became free of the forfeiture provisions. Accordingly, the shares
  were revalued using the September 30, 1994 fair value. The amounts relating
  to (1) the Company's CEO totaled $18.6 million and was recorded as special
  compensation expense, and (2) Henry Schein's CEO totaled $5.7 million, and
  the excess of that amount over the 1992 fair value totaled $3.1 million,
  which was recorded as a capital distribution.
 
    (iv) SHI retained the services of investment banking and financial
  advisory firms. Of the fees paid to these firms, $1.5 million was charged
  to retained earnings, as such amount related to the Minority Investor
  Transaction.
 
    (v) SHI redeemed its outstanding preferred stock for $25.7 million,
  paying $20.7 million in cash and canceling a $5.0 million loan to a
  preferred stockholder.
 
    (vi) SHI established a supplemental retirement program for its CEO and
  recognized as current expense the Company's obligation under the plan,
  estimated at $5.0 million. This liability is included in Other Liabilities
  in the accompanying balance sheets.

  Professional fees incurred by the Company of $4.2 million in 1994 in
connection with the Restructuring were recorded as restructuring expense.
 
NOTE 3--ACQUISITIONS AND INVESTMENTS IN INTERNATIONAL AFFILIATES
 
  The Company acquired all the outstanding capital stock of Marsam
Pharmaceuticals Inc. ("Marsam") in September 1995 for $245.0 million in cash.
Marsam develops, manufactures and markets generic injectable prescription
drugs. The acquisition was accounted for as a purchase. The purchase price of
$245.0 million exceeded the book value of the net assets acquired by $193.0
million. Of the excess purchase price, $92.0 million was allocated to increase
the net assets acquired to fair value, principally related to regulatory
facility and product approvals. Acquired in-process Marsam research and
development projects were valued at $30.0 million and were expensed at the
time of the acquisition. Goodwill of $108.0 million, consisting of the
remaining excess purchase price of $71.0 million and a $37.0 million deferred
tax liability resulting from the write-up of the net assets to fair value. is
being amortized over 25 years. Marsam's results of operations have been
included in the consolidated statements of operations since the date of
acquisition.
 
  The following summarized, unaudited pro forma results of operations for 1994
and 1995 assume the acquisition occurred as of the beginning of 1994. In
preparing the pro forma data, adjustments have been made for the amortization
of goodwill and other intangibles acquired, the interest expense related to
borrowing agreements to finance the purchase price and, in 1994 only, the
write-off of acquired in-process Marsam research and development projects.
Since the valuation of Marsam's net assets and in-process research and
development projects may have differed at January 1, 1994 from amounts
recorded at September 1, 1995, the information presented is not necessarily
indicative of results of operations that would have occurred had the
acquisition been consummated at the beginning of the respective periods, or of
future results of the combined companies.

</TABLE>
 
  During 1995 and 1996, the Company invested approximately $3.5 million and
$2.0 million, respectively, and $0.2 million for the nine months ended
September 27, 1997, to acquire up to a 50% interest in each of several
international pharmaceutical businesses. These businesses are jointly owned
with subsidiaries of Bayer AG, the parent of Bayer Corp., a minority investor
in the Company. These investments are accounted for under the equity method
and are included in Other Assets in the accompanying balance sheets. The
Company recorded losses of approximately $0.3 million and $3.3 million in
fiscal 1995 and fiscal 1996, respectively, and $1.6 million and $2.7 million
for the nine months ended September 28, 1996 and September 27, 1997,
respectively, as its share of the operating results of these businesses.
Additionally, the Company incurred expenses of approximately $2.1 million and
$2.9 million in fiscal 1995 and fiscal 1996, respectively, and approximately
$2.0 million and $1.8 million for the nine months ended September 28, 1996 and
September 27, 1997, to identify, evaluate, and establish these and other
potential international business ventures. All equity losses and other
expenses resulting from the Company's investments in international businesses
in fiscal 1995 and fiscal 1996 are included in other expense, net, in the
accompanying statements of operations. The Company generally anticipates that
these international businesses will not have significant revenues or
operations for a period of two to three years, during which time the
businesses incur expenses to register products in anticipation of future
sales.

  In September 1995, the Company entered into a secured revolving credit and
term loan agreement (as amended, the "credit agreement") with a group of banks
to provide funds for the acquisition of Marsam, the repayment of certain of
its debt, working capital and general corporate purposes. The credit agreement
provided a term loan facility of $250.0 million and a revolving credit
facility of $100.0 million. In December 1996, the Company prepaid $100.0
million of the term loan portion of the credit agreement using the proceeds
from a new senior subordinated loan (see below). As a result of this payment
and a scheduled payment, the term loan facility was reduced to $145.0 million.
Quarterly principal payments on the term loan commence in September 1998 and
end in the year 2001. The revolving credit usage was $30.0 million, $41.0
million and $26.0 million as of December 30, 1995, December 28, 1996 and
September 27, 1997, respectively. The $100.0 million revolving credit line is
available through December 2001. Amounts borrowed under the revolving credit
facility are expected to be repaid during the next year and, accordingly, are
classified as current in the accompanying balance sheets.
 
  Borrowings under the credit agreement bear interest, which is payable at
least quarterly, at a rate equal to the bank's floating base rate plus a
premium ranging from zero to 1.50%, or at a rate equal to LIBOR plus a premium
ranging from 0.75% to 2.50%, depending on the type of borrowing and the
Company's performance against certain criteria. The effective borrowing rate
was 7.14%, 8.10% and 7.80% at December 30, 1995, December 28, 1996 and
September 27, 1997, respectively. A commitment fee ranging from 0.25% to 0.50%
per annum of the unused daily amount of the total commitment is payable
quarterly.
 
  Borrowings under the credit agreement are secured by a mortgage on all real
property, liens on inventory and receivables and a pledge of subsidiaries'
stock. The debt is guaranteed by the Company's domestic subsidiaries.
 
  The credit agreement contains limitations and restrictions concerning
investments, acquisitions, capital expenditures, debt, liens, transactions
with stockholders, dividend payments and borrowings. In addition, the
agreement requires the Company to maintain minimum net worth levels and
certain ratios (as defined) of leverage to EBITDA, working capital and fixed
charge coverage. Amounts available for dividends as of December 28, 1996 were
not material.
 
  In December 1996, the Company entered into an agreement for a $100.0 million
senior subordinated loan with a lead-manager of the credit agreement. The
proceeds of the loan were used to prepay principal on the term loan of the
credit agreement. The effective borrowing rate was 9.60% and 9.72% as of
December 28, 1996 and September 27, 1997, respectively. Outstanding borrowings
under the senior subordinated loan agreement bear interest, payable quarterly,
at a rate equal to LIBOR plus 4% or the bank's floating base rate plus 3%,
through January 31, 1998. Thereafter, the principal amount of the loan will be
increased to reflect related fees due and will mature in five years. Interest
will be due semi-annually and the interest rate will be fixed at a new rate.

  In connection with entering into the credit agreement, the Company incurred
costs of $5.9 million in 1995. During 1996, the Company incurred costs of $2.3
million in connection with entering into the senior subordinated loan and
amending the credit agreement. The Company capitalized these costs, which are
included in Other Assets in the accompanying balance sheets. The amounts
amortized in 1995 and 1996 were $0.7 million and $2.6 million, respectively.
 
  At December 28, 1996, aggregate required principal payments for the
succeeding four years, the remaining term under existing long-term debt
agreements, excluding the revolving credit facility, are $15.3 million in
1998, $38.2 million in 1999, $45.8 million in 2000 and $45.8 million in 2001.

 Operating Leases
 
  The Company leases facilities and equipment under operating leases expiring
through 2007. Some of the leases have renewal options and most contain

  Total rental expense for the fiscal years ended 1994, 1995 and 1996 was
approximately $3.7 million, $4.7 million and $5.4 million, respectively and
$3.9 million and $4.1 million for the nine months ended September 28, 1996 and
September 27, 1997, respectively.
 
  The Company has an agreement to lease warehousing space through September
1999, and then purchase this property for $5.3 million in October 1999. In
1997 the Company intends to exercise its option to purchase this property. The
property consists of a building of approximately 109,800 square feet on
approximately 8.5 acres of land. The purchase price includes a $0.3 million
deposit paid in 1994.
 
 Employee Benefit Plans
 
  During 1996, the Company merged its defined contribution retirement plans
into one plan. The discretionary contributions to the plan vest to employees
over several years. Additionally, employees are permitted to make pre-tax
contributions to the plan with the Company making matching contributions. The
contributions to these plans which were charged to operations, as determined
by the Board of Directors, amounted to approximately $4.2 million, $4.9
million and $3.5 million for the fiscal years ended 1994, 1995 and 1996,
respectively and $3.7 million and $4.7 million for the nine months ended
September 28, 1996 and September 27, 1997, respectively.
 
  The Company has entered into deferred compensation agreements with certain
officers of the Company. As of December 1996, obligations under these
agreements were approximately $6.6 million, assuming the officers remain with
the Company over the vesting period of four years. These agreements provide
for accelerated vesting

if there is a change in control of the Company and under certain other
conditions. The Company expensed $2.7 million, $2.0 million, and $4.8 million
in the fiscal years ended 1994, 1995, and 1996, respectively, and $1.7 million
and $1.1 million in the nine months ended September 28, 1996 and September 27,
1997, respectively, in connection with these agreements.
 
  The Company established an unfunded supplemental retirement program for its
CEO during 1994. The estimated obligation of $5.0 million is included in Other
Liabilities in the accompanying balance sheets.
 
  The Company maintains a Book Equity Appreciation Rights Program (the
"Program") to allow certain employees to benefit from an increase in the
Company's book value as calculated according to a formula defined in the
Program. All participants are fully bested in their book equity appreciation
rights ("BEARs") and the Company does not intend to make any additional grants
of BEARs. Amounts charged to results of operations were not material in any
period presented.
 
 Product Technology Licensing and Development
 
  On September 1, 1994, the Company entered into a worldwide technology
licensing and development agreement with a U.K.-based pharmaceutical
development company for the development of a portfolio of oral controlled
release and/or transdermal products. Under the terms of the agreement, the
Company is obligated to pay product licensing fees and development costs
totaling $32.0 million, dependent on achievement of interim milestones. In
1994, the Company incurred obligations totaling $5.3 million under the
agreement, consisting of a $5.0 million licensing fee, which was capitalized,
and $0.3 million in development costs, which were charged to research and
development expense. The Company paid and expensed $2.1 million in development
costs in 1995. In 1996, the Company incurred obligations totaling $3.0
million, consisting of a $0.5 million licensing fee, which was capitalized,
and $2.5 million in development costs which were charged to research and
development expense. The remaining commitment under the agreement as of
December 28, 1996 was $21.6 million, subject to the completion of interim
milestones.
 
  On September 30, 1996, the Company entered into a marketing and distribution
agreement with a corporation to jointly commercialize a certain product. Under
the terms of the agreement, the Company is obligated to pay product licensing
fees and development costs of $12.0 million, dependent on the achievement of
certain milestones. In 1996, the Company paid and capitalized a $2.0 million
product license fee.
 
 Consulting Agreement
 
  The Company has a series of agreements (collectively, the "Consulting
Agreement") with a patent attorney (the "Consultant"). Under the Consulting
Agreement, the Consultant, together with the Company, identified certain
patents on branded pharmaceutical products which might be susceptible to a
challenge and the Consultant acted as counsel to the Company in those
instances where it decided to proceed with a patent challenge.
 
  The Consulting Agreement generally provides that if a challenge based on an
opinion of the Consultant results in either a favorable judicial determination
which enables the Company to market a generic version of the product or in a
settlement, the Company will pay the Consultant one half of the adjusted gross
profit (as defined) from its sales of the generic versions of the patented
product (until the date on which the patent would normally have expired) or
one half of the proceeds of any settlement.
 
  In 1994, the Company settled two such patent challenges. One of the
settlements involved a license grant to the Company to market the product
which was the subject of the challenge beginning in 1996. The other allows for
future cash payments and/or license rights to the Company. In connection with
the second settlement, the Company received revenues of $5 and $12.5 million
in 1995 and 1996, respectively, and $12.5 million and $25.0 million in the
nine months ended September 28, 1996 and September 27, 1997, which are
included in Net revenues in the accompanying statements of operations.

  Profit-sharing expenses pursuant to the Consulting Agreement and included in
Cost of sales were $2.5 million in fiscal 1995, $14.9 million in fiscal 1996
and $9.3 million and $24.5 million for the nine months ended September 28,
1996 and September 27, 1997, respectively. In 1994, there were no related
profit-sharing expenses.
 
CONTINGENCIES
 
 Litigation
 
  The Company is a defendant in several product liability cases. These cases
are typical for a company in the pharmaceutical industry. The Company also is
involved in other proceedings and claims of various types. Management
presently believes that the disposition of all such known proceedings and
claims, individually or in the aggregate, will not have a material adverse
effect on the Company's financial position, operations or liquidity.
 
NOTE 11--STOCKHOLDERS' EQUITY AND STOCK OPTIONS
 
  Common Stock
 
  The Company has Class A Common Shares ("Class A") and Class B Common Shares
("Class B"). Each of the two classes of stock are identical except that Class
B shares are currently non-voting. Upon the earlier occurrence of an initial
public offering or May 15, 1999, each authorized share of Class B will be
automatically reclassified as and converted into one new Class A share.
 
  Upon the closing of the Company's planned initial public offering, the Class
A and Class B will convert on a one-for-one basis to new shares of the
Company's common stock.
 
  At December 30, 1995, December 28, 1996 and September 22, 1997, the Company
had 183,722, 183,244 and 183,244 Class A issued and outstanding, respectively.
The Company had 90,020 Class B for all periods presented.
 
  During 1996, the Company agreed to repurchase 478 Common Shares for
approximately $1.0 million from a former executive of the Company. These
shares were retired in 1996.
 
  Stock Option Plan
 
  In October 1995, the Financial Accounting Standards Board issued SFAS No.
123, Accounting for Stock- Based Compensation. SFAS No. 123 encourages
entities to adopt that method in place of the provisions of Accounting
Principles Board Opinion Number 25, Accounting for Stock Issued to Employees
("APB No. 25"), for all arrangements under which employees receive shares of
stock or other equity instruments of the employer or the employer incurs
liabilities to employees in amounts based on the price of its stock. The
Company continues to account for such transactions in accordance with APB No.
25 and, as required by SFAS No. 123, has provided pro forma information
regarding net income as if compensation cost for the Company's stock option
plan had been determined in accordance with the fair value method prescribed
by SFAS No. 123.
 
  Under a 1993 Stock Option Plan, a 1995 Non-Employee Director Stock Option
Plan, and effective March 3, 1997, a 1997 Stock Option Plan the Company may
grant non-qualified and incentive stock options to certain officers, employees
and directors. The options expire ten years from the grant date. The options
may be exercised subject to continued service (three to five years) and
certain other conditions. Accelerated vesting occurs following a change in
control of the Company and under certain other conditions. The Company may
grant an aggregate of 55,797 shares under the plans. However, 3,503 shares
under the 1993 Stock Option Plan will not be granted.

  The Company estimates the fair value of each stock option at the grant date
by using the Black-Scholes option-pricing model with the following weighted
average assumptions used for grants in 1995 and 1996: no dividend yield,
expected volatility of 0.01%, risk free interest rates of 5% to 7%, expected
lives of 10 years and a discount for marketability of 25%. If compensation
cost for the Company's stock option plan had been determined in accordance
with SFAS No. 123, net income (loss) would have been reduced in 1995 and 1996
by approximately $1.0 million and $2.3 million, respectively.

NOTE 17--SUBSEQUENT EVENTS
 
  In November 1997, the Company entered into a Commitment Letter with an
investment banking firm providing for the issuance and sale of $100 million of
Senior Floating Rate Notes due 2004. Interest on the notes will be due
quarterly at a LIBOR-based rate. The Company expects this offering to be
completed in December 1997, at which time the proceeds will be used to retire
the existing $100 million senior subordinated loan (Note 9).
 
  The Company has filed a registration statement covering an initial public
offering under which it anticipates raising net proceeds of approximately $45
million upon the sale of its common stock. If the offering is consummated, the
net proceeds will be used in whole or in part to pay down the Company's debt.

1. BUSINESS:
 
  The Company was founded in 1985 and is engaged in the business of
developing, manufacturing, marketing and distributing generic injectable
prescription drug products. The Company markets penicillin, cephalosporin and
other injectable products.
 
  The Company, prior to 1993, operated under joint venture agreements with
E.R. Squibb & Sons, Inc. ("Squibb") and Geneva Pharmaceuticals, Inc.
("Geneva"). Both joint ventures required the Company to manufacture its
products and ship them to its joint venture partner, with the partner then
being responsible for marketing and distributing the Company's products. The
joint venture agreement with Squibb (as amended, the "Joint Agreement") was in
place from December 1985 to June 1990, and was replaced with a restructure and
release agreement (the "Restructure Agreement") which required each party to
manufacture for the other certain products through May 1993. The Restructure
Agreement was later extended to December 31, 1994.
 
  The joint venture agreement with Geneva (the "Distribution Agreement") was
executed in June 1990 and was in place until July 1992, at which time the
Company filed a complaint against Geneva asserting certain breaches by Geneva
of its fiduciary duties to the Company and of its contractual obligations
under the Distribution Agreement. The financial statements for 1992 include
approximately $1,100,000 of costs related to the termination of the
Distribution Agreement. In July 1993 the Company and Geneva executed a
settlement agreement (the "Settlement Agreement") which resolved the
outstanding litigation between the two companies. Pursuant to the Settlement
Agreement, Geneva paid the sum of $550,000 to the Company to balance the
accounts between the parties and in full settlement of all claims and
counterclaims. In 1993, as a result of the settlement, the Company reduced
previously accrued liabilities by approximately $600,000.
 
  In 1993 the Company began to develop its own sales and marketing force to
sell its products under the Marsam label and other private labels. The Company
markets these products to pharmaceutical wholesalers and distributors,
hospitals, home infusion companies and other medical providers. In 1994, more
than 75% of revenues were from direct sales of Marsam-label products.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Basis of Presentation:
 
  The consolidated financial statements include to accounts of Marsam
Pharmaceuticals Inc. and subsidiary. All intercompany transactions are
eliminated in consolidation investments in corporate joint ventures in which
the Company has a 20 to 50 percent ownership are accounted for by the equity
method. Other investments, less than 20 percent owned, are carried at their
original cost. Equity and cost investments are included in other assets in the
consolidated financial statements.
 
 Revenue Recognition:
 
  Sales to Geneva in 1992 were at a price equal to the estimated production
cost per unit plus 10% for products manufactured by Marsam and the amount per
unit actually paid plus 5% for sourced injectable products ("Transfer Price").
At the time of shipment to Geneva, revenue was recognized at the Transfer
Price less one-half of the applicable 10% or 5% profit. The portion of the
profit which was deferred was recognized as revenue when Geneva shipped the
Products. Net Proceeds were earned when the products were sold by Geneva. Net
Proceeds were to generally represent Geneva's net sales of the Products less
the applicable Transfer Price and certain specific distribution and operating
costs.
 
 Principal Customers:
 
  Sales to Squibb were $8,090,100, $8,126,500, and $7,375,800 for each of the
years ended December 31, 1994, 1993 and 1992, respectively.

                  MARSAM PHARMACEUTICALS INC. AND SUBSIDIARY
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Sales to Geneva were $578,700 and $7,297,400 for the years ended December
31, 1993 and 1992, respectively.
 
  Sales of Marsam label products are sold predominately through pharmaceutical
wholesalers to third parties under contract with the Company; thus, no one
customer comprises a significant portion of sales.
 
 Credit Risk:
 
  Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash and cash
equivalents, investments, and accounts receivable. The Company invests cash
and cash equivalents in savings and money market accounts of high credit
qualified financial institutions, as well as high credit commercial paper and
time deposits. Investments are placed in investment grade debt. Accounts
receivable are substantially comprised of amounts from sales to relatively few
large contract and wholesale customers. Credit limits, ongoing credit
evaluation and account monitoring procedures are utilized to minimize the risk
of loss. Collateral is generally not required.
 
 Cash Equivalents:
 
  Cash equivalents consist of those securities with maturities of three months
or less when purchased.
 
 Investments:
 
  Effective January 1, 1994, the Company adopted the provisions of Statement
of Financial Accounting Standards No. 115, "Accounting for Certain Investments
in Debt and Equity Securities." There was no cumulative effect of adopting
SFAS 115 as of January 1, 1994, and prior period financial statements have not
been restated. At December 31, 1994 the Company owned current "available-for-
sale" marketable securities which are carried at fair market value on the
balance sheet. Unrealized gains or losses are recorded directly to
stockholders equity, net of applicable income taxes. At December 31, 1994,
there were no unrealized gains or losses related to these securities, as the
cost was equal to fair value on that date.
 
  Prior to 1994, the Company recorded investments in marketable securities at
the lower of cost or fair market value. At December 31, 1993, the Company had
investments with a cost equal to their fair market value.
 
  For the years ending December 31, 1994, 1993, and 1992, the Company realized
interest and dividend income of $732,100, $521,100 and $990,700, respectively,
which is included in other income.
 
 Inventories:
 
  Inventories are stated at the lower of cost or market. Cost is determined by
the first in, first out method.
 
 Property and Equipment:
 
  Property and equipment is stated at cost. Depreciation of property and
equipment is computed using the straight-line method based on the estimated
useful lives of the assets, which range from five to forty years. Amortization
of leasehold improvements is recorded ratably over the remaining lease term or
useful life, if shorter.
 
  Maintenance and repairs are charged to expense as incurred; major renewals
and improvements are capitalized. Gains or losses on the disposition of fixed
assets are reflected in income.
 
 Income Taxes:
 
  The Company records deferred taxes by using the asset and liability method.
Under this method, deferred tax assets and liabilities are determined based on
differences between financial reporting and tax bases of assets
 
                                     F-28

                  MARSAM PHARMACEUTICALS INC. AND SUBSIDIARY
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
and liabilities and are measured using the enacted tax rates and laws that
will be in effect when the differences are expected to reverse. Valuation
allowances are established when necessary to reduce deferred tax assets to the
amounts expected to be realized. Federal tax credits are recognized as
deferred tax assets.
 
  Net Income (Loss) per Share:
 
  Net income (loss) per share was calculated based upon the weighted average
common and common equivalent shares outstanding. Common share equivalents
included in the calculation represent shares issuable upon assumed exercise of
stock options which would have a dilutive effect in years where there are
earnings. Equivalents had no material effect on the computation in 1994, 1993,
or 1992.
 
  Statements of Cash Flows:
 
  At December 31, 1994, 1993 and 1992, approximately $454,800, $85,900 and
$279,700, respectively of amounts payable relating to the acquisition of
property and equipment were excluded from the statement of cash flows. In 1994
and 1992, the Company paid income taxes of $5,200 and $5,800, respectively.
 
3. INVENTORY:
 
  At December 31, 1994 and 1993, inventory consisted of the following:

  In 1994 and 1993, current federal income tax expense was generated on
alternative minimum taxable income. The current federal income tax provisions
on earnings for 1994 and 1993 were offset by the utilization of federal net
operating loss carryforwards. Utilization of federal net operating loss
carryforwards in 1994, created by tax expense for employee stock options,
resulted in a $365,100 increase to additional paid-in capital. There was no
current federal income tax provision for 1992, due to the loss incurred by the
Company. A deferred federal income tax benefit arose in 1994 due to the
recognition of the Company's deferred tax assets. In the fourth quarter of
1994, a net $300,000 benefit was recognized due to a reduction in the deferred
tax asset valuation allowance. A deferred federal income tax provision arose
in 1993 and 1992 from temporary differences on which net operating loss
carryforwards could not be utilized. At December 31, 1994, the Company had
utilized the balance of its net operating loss carryforwards for federal tax
purposes. At December 31, 1994 the Company had utilized the balance of its
alternative minimum tax net operating loss carryforwards and had available
alternative minimum tax credit carryforwards of $198,600 which do not expire.
 
  The current state income tax provisions for 1994 and 1993 were offset by
utilization of state net operating loss carryforwards. There was no current
state income tax provision for 1992 due to the loss incurred by the Company.
In 1994, a deferred state income tax benefit arose from the recognition of the
Company's deferred tax assets. In 1993, a deferred state income tax provision
arose from temporary differences on which net operating loss carryforwards
could not be utilized. At December 31, 1994, the Company had available state
net operating loss carryforwards of $1,877,600 to offset future state taxable
income. The state net operating loss carryforwards expire 1996 through 1999.

6. SETTLEMENT AGREEMENT WITH GREAT LAKES CHEMICAL CORPORATION:
 
  On July 18, 1994, the Company and Great Lakes Chemical Corporation ("GLCC")
executed a comprehensive settlement agreement which resolved the outstanding
litigation between them concerning the failure of GLCC to supply the Company
certain raw materials in accordance with the agreement between them. Under the
terms of the settlement, GLCC paid $2.35 million to the Company and agreed to
begin supplying the Company with an inhaled anesthetic raw material commencing
upon the availability of production quantities from its existing facility and
continuing for at least five years after completion of a new, larger
production facility. The payment received by the Company on July 19, 1994, is
being ratably recognized as income during the period of July 1, 1994 through
June 30, 1995, the period during which the Company expected to market the
product but will be unable to market because of GLCC'S failure to supply the
raw material. For the year ended December 31, 1994, the Company recognized
$1,175,000, of the $2.35 million received from GLCC, as other income. The
balance of $1,175,000 is included as deferred revenue at December 31, 1994.
 
  If GLCC fails to deliver agreed quantities of product by specified dates, or
if the product does not receive FDA approval by July 15, 1995, the Company is
entitled to be reimbursed for lost profits associated with the inability of
the Company to market the product. Such payments can be received until January
15, 1998.
 
7. INVESTMENT IN BUSINESS:
 
  On September 23, 1994, the Company purchased, for $1,500,000, a minority
equity interest in Sabratek Corporation ("Sabratek"), a medical device
manufacturer. The Company received one million shares of cumulative
convertible preferred stock of Sabratek in return for its investment. The
Company has committed to an additional investment of $500,000 provided that
Sabratek achieves certain goals. The Company has also received warrants to
purchase an additional 1.5 million shares of Sabratek. The Company accounts
for this investment under the cost method, as the Company has a less than 20%
interest in Sabratek.

$252,800 and $45,200 in 1995, 1996 and 1997, respectively. The Company has
agreed to purchase this property, which consists of a building of
approximately 109,800 square feet on approximately 8.8 acres of land, in March
1997. The purchase price is $5,319,000 and includes a $250,000 deposit which
was paid during 1994, and two installment payments of $3,000,000 in March 1997
and $2,069,000 in October 1997.

9. CAPITAL TRANSACTIONS:
 
 Stock Option Plan:

Accordingly, the accompanying unaudited consolidated financial statements do

3. SETTLEMENT AGREEMENT WITH GREAT LAKES CHEMICAL CORPORATION
 
  On July 18, 1994, the Company and Great Lakes Chemical Corporation (GLCC)
executed a comprehensive settlement agreement which resolved the outstanding
litigation between them concerning the failure of GLCC to supply the Company
certain raw materials. Under the terms of the settlement, GLCC paid $2.35
million to the Company and agreed to begin supplying the Company with the
inhaled anesthetic raw material commencing upon the availability of production
quantities from its existing facility and continuing for at least five years
after completion of a new, larger production facility. The payment, received
by the Company on July 19, 1994, was ratably recognized as income during the
period of July 1, 1994 through June 30, 1995, the period during which the
Company originally expected to launch the product. For the three and six-month
periods ended June 30, 1995, the Company recognized $587,500 and $1,175,000,
respectively, of the $2.35 million received from GLCC, as other income.
 
  If GLCC fails to deliver agreed quantities of product by specified dates the
Company is entitled to be reimbursed for lost profits associated with the
inability of the Company to market the product. Such payments can be received
until January 15, 1998.
 
4. INCOME TAXES
 
  The provision for income tax expenses is based on an estimated full year
effective income tax rate. The rate reflects the Company's utilization of
certain federal tax credits and its federal and state net operating loss
carryforwards during 1995. The provision for income tax for the same periods
in 1994 was insignificant due to the availability of federal and state net
operating loss carryforwards.

5. NET INCOME PER SHARE
 
  Net income per share is based on fully diluted weighted average common and
common equivalent shares outstanding for the three and six-month periods ended
June 30, 1995 and 1994.

                  FORM OF TRANSFEREE LETTER OF REPRESENTATION
 
Schein Pharmaceutical, Inc.
100 Campus Drive
Florham Park, NJ 07932
Attn: Chief Financial Officer
 
Ladies and Gentlemen:
 
  This certificate is delivered to request a transfer of $           principal
amount of the Senior Floating Rate Notes Due 2004 (the "Notes") of Schein
Pharmaceutical, Inc. (the "Company").
 
  Upon transfer, the Notes would be registered in the name of the new
beneficial owner as follows:
 
     Name: _________________________________________________________
 
     Address: ______________________________________________________
 
     Taxpayer ID Number: ___________________________________________
 
The undersigned represents and warrants to you that:
 
  1. We are an institutional "accredited investor" (as defined in Rule
501(a)(1),(2),(3) or (7) under the Securities Act of 1933, as amended (the
"Securities Act")) purchasing for our own account or for the account of such
an institutional "accredited investor" at least $250,000 principal amount of
the Notes, and we are acquiring the Notes not with a view to, or for offer or
sale in connection with, any distribution in violation of the Securities Act.
We have such knowledge and experience in financial and business matters as to
be capable of evaluating the merits and risk of our investment in the Notes
and we invest in or purchase securities similar to the Notes in the normal
course of our business. We and any accounts for which we are acting are each
able to bear the economic risk of our or its investment.
 
  2. We understand that the Notes have not been registered under the
Securities Act and, unless so registered, may not be sold except as permitted
in the following sentence. We agree on our own behalf and on behalf of any
investor account for which we are purchasing Notes to offer, sell or otherwise
transfer such Notes prior to the date which is two years after the later of
the date of original issue and the last date on which the Company or any
affiliate of the Company was the owner of such Notes (or any predecessor
thereto) (the "Resale Restriction Termination Date") only (a) to the Company,
(b) pursuant to a registration statement which has been declared effective
under the Securities Act, (c) in a transaction complying with the requirements
of Rule 144A under the Securities Act, to a person we reasonably believe is a
qualified institutional buyer under Rule 144A (a "QIB") that purchases for its
own account or for the account of a QIB and to whom notice is given that the
transfer is being made in reliance on Rule 144A, (d) pursuant to offers and
sales that occur outside the United States within the meaning of Regulation S
under the Securities Act, (e) to an institutional "accredited investor"
(within the meaning of Rule 501(a)(1),(2),(3), or (7) under the Securities
Act) that is purchasing for its own account or for the account of such an
institutional "accredited investor", in each case in a minimum principal
amount of Notes of $250,000 or (f) pursuant to any other available exemption
from the registration requirements of the Securities Act, subject in each of
the foregoing cases to any requirement of law that the disposition of our
property or the property of such investor account or accounts be at all times
within our or their control and in compliance with any applicable state
securities laws. The foregoing restrictions on resale will not apply
subsequent to the Resale Restriction Termination Date. If any resale or other
transfer of the Notes is proposed to be made pursuant to clause (e) above
prior to the Resale Restriction Termination Date, the transferor shall deliver
a letter from the transferee substantially in the form of this letter to the
Company and the Trustee, which shall provide, among other things, that the
transferee is an institutional "accredited investor" (within the meaning of
Rule 501(a)(1),(2),(3) or (7) under the Securities Act) that is acquiring such
Notes for investment purposes and not for distribution in violation of the
Securities Act. Each purchaser acknowledges that the Company and the Trustee
reserve the right prior to any offer, sale or other transfer prior to the
Resale Termination Date of the Notes pursuant to clause (d),(e) or (f) above
to require the delivery of an opinion of counsel, certifications and/or other
information satisfactory to the Company and the Trustee.
 
                                      A-1

  3. We agree on our own behalf and on behalf of any investor account for
which we are purchasing the Notes that (i) if it is an insurance company, the
funds to be used to purchase the Notes by it constitute (A) assets of an
insurance company general account maintained by it and the acquisition and
holding of each such Note by such account is exempt under United States
Department of Labor Prohibited Transaction Class Exemption ("PTCE") 95-60 or
(B) assets of an insurance company pooled separate account and the acquisition
and holding of each such Note by such account is exempt under PTCE 90-1, and
(ii) no part of the funds to be used to purchase the Notes to be purchased by
it constitute assets of any plan or employee benefit plan such that the use of
such assets constitutes a non-exempt prohibited transaction under the Employee
Retirement Income Security Act of 1974, as amended ("ERISA") or the Internal
Revenue Code of 1986, as amended (the "Code"). The representation is based
upon the purchaser's determination that a statutory or administrative
exemption is applicable or that the Company and its Affiliates are not parties
in interest or disqualified persons with respect to the purchaser or holder
plan or employee benefit plan. As used in this paragraph, the terms "employee
benefit plan" and "party in interest" shall have the meanings assigned to such
terms in Section 3 of ERISA, the term "Affiliate" shall have the meaning
assigned to such term in Section 407(d)(7) of ERISA and the terms
"disqualified person" and "plan" shall have the meanings assigned to such
terms in Section 4975 of the Code.

expense, to perform the work and all other obligations on the part of the
Developer to be performed under the Development Agreement in accordance with the
terms and conditions thereof ("Landlord's Work").  Landlord agrees to perform
Landlord's Work in a manner which shall cause the least possible interference to
Tenant in the performance of Tenant's Work (as defined in the Development
Agreement) and Tenant's use and enjoyment of the Demised Premises.  Landlord
shall continuously keep Tenant fully informed of the progress of Landlord's
Work; and Tenant's representatives at all times shall have access to the Demised
Premises during Landlord's Work for purposes of inspection.  In addition,
Landlord shall cooperate with Tenant so that Tenant is able to commence
preparing the Demised Premises for Tenant's use and occupancy.

          Tenant is hereby permitted to enter the Demised Premises for the
purpose of doing Tenant's Work and making the same ready for Tenant's occupancy.
Provided that all "Conditions" on the part of Developer to be satisfied pursuant
to and as defined in the Development Agreement have been satisfied in full,
Tenant agrees promptly to commence Tenant's Work and to use due diligence and
continuity to complete Tenant's Work, subject to unavoidable delays caused by
events beyond the control of Tenant.  Tenant and Landlord agree that:

          (a)  Tenant will employ contractors approved by Landlord, which
approval Landlord agrees not to unreasonably withhold;

                                       2
<PAGE>
 
          (b)  Except to the extent that any of Tenant's Work shall constitute a
portion of the Demised Premises with respect to which Landlord shall have an
obligation to maintain or repair in accordance with another provision of this
Lease, Landlord shall not be responsible for any materials installed or
delivered, or any work performed, in connection with Tenant's Work;

          (c)  Landlord and Tenant will cooperate with each other to coordinate
the schedule of the performance of Tenant's Work and Landlord's Work so that the
installation or delivery of such materials or work performed shall not interfere
with the other's work or the other's workmen;

          (d)  Any materials so installed or work performed by Tenant shall be
made in conformity with all Laws and Ordinances (as hereinafter defined), shall
not violate any permit issued to Landlord (which Landlord has identified to
Tenant and Tenant's architect) and shall be made after Tenant obtains any
permits required for such materials and work;

          (e)  Tenant and Landlord shall cooperate with each other to coordinate
the employment of labor for the performance of any work required to be done by
Tenant or Landlord, which is compatible with the labor employed by the other so
as to avoid any labor dispute or work stoppage and agrees to cease work promptly
upon notice from the other if any is threatened; and

          (f)  Tenant shall, during such period, perform and comply with all the
terms, covenants and conditions of this Lease to be performed by Tenant other
than the payment of any charges for rent or additional rent required to be paid
by Tenant hereunder.

          2.4  For the purposes of this Lease, the Commencement Date shall mean
the date on which the last of all the following shall have occurred or have been
performed:

                 (i)  Landlord shall have Substantially Completed Landlord's
Work and Tenant shall have been provided with at least ninety (90) days from the
date on which Landlord has Substantially Completed Landlord's Work to perform
Tenant's Work. As used in this Lease, "Substantially Completed" or "Substantial
Completion" shall mean completed or completion except for details of
construction, decoration and mechanical, electrical or other adjustments, which
do not materially interfere with Tenant's use of the Demised Premises;

                (ii)  All utilities have been connected in the Building and are
in good working order;

               (iii)  A temporary or permanent certificate of occupancy shall
have been obtained by Landlord from the

                                       3
<PAGE>
 
appropriate local authority indicating that the Demised Premises may be lawfully
occupied for the purposes set forth herein;

                 (iv)  Landlord shall have delivered to Tenant the "Commencement
Date Certificate and Agreement" in the form annexed hereto as Exhibit D;

                 (v)   Landlord shall have obtained from any mortgagee of the
Demised Premises, a Non-Disturbance Agreement, as such term is defined herein;
and

                 (vi)  All other Conditions under and as defined in the
Development Agreement on the part of the Developer thereunder to be satisfied
have been satisfied in full.

          In the event that the Commencement Date occurs prior to Landlord's
having obtained a permanent certificate of occupancy, Landlord shall be
obligated to perform all work and supply all material necessary to obtain a
permanent certificate of occupancy prior to the expiration of the temporary
certificate of occupancy.

          2.5  Within one hundred twenty (120) days after the Substantial
Completion of the Demised Premises, Tenant shall deliver to Landlord a statement
or statements setting forth the items of work to be performed by Landlord
hereunder, if any, which have not been completed or which are defective.
Landlord agrees to complete such items with reasonable diligence. Landlord shall
not be relieved of its responsibility with respect to Landlord's Work as a
result of Tenant's failure to identify defects in Landlord's Work, unless Tenant
has not notified Landlord of such defects within twelve (12) months from the
Commencement Date of this Lease.  Defects which are not reasonably apparent from
Tenant's contemplated use of the Demised Premises shall not be subject to such
twelve (12) month limitation.  Landlord agrees to assign to Tenant any warranty
and/or guaranty of work and/or materials from any contractor and/or materialmen
at the end of such twelve (12) month period and shall cooperate with Tenant in
enforcing all such warranties and/or guaranties.  Landlord shall not be
obligated to repair or restore any damage to Demised Premises caused by Tenant,
or Tenant's employees or contractors.

          2.6  Within thirty (30) days after the request of either party hereto
after the Commencement Date of this Lease shall have been determined, Landlord
and Tenant shall execute, acknowledge and deliver to each other duplicate
originals of an instrument in form and content reasonably satisfactory to them
setting forth such date.  The failure of either party to promptly execute and
deliver such instrument shall in no way affect the commencement of the term
hereof.

                                       4

          At the request of either party, Landlord and Tenant shall promptly
execute, acknowledge and deliver a memorandum with respect to this Lease
sufficient for recording, which Tenant may record at Tenant's cost and expense.
Such memorandum shall not in any circumstance be deemed to change or otherwise
affect any of the obligations or provisions of this Lease.

          2.7  Anything set forth in this Lease to the contrary notwithstanding,
this Lease shall not be effective, nor shall Tenant have any obligations to
perform hereunder, unless and until all Conditions under and as defined in the
Development Agreement on the part of the Developer thereunder to be satisfied
have been satisfied in full.  In the event that Tenant elects to terminate the
Development Agreement in accordance with the terms thereof, this Lease will
automatically terminate without the necessity of any additional action on the
part of either Landlord or Tenant hereunder.

                                    ------

          3.1  Tenant agrees to pay to Landlord a fixed minimum rent
(hereinafter referred to as the "Fixed Minimum Rent") at the rates set forth on
Exhibit E attached hereto.  Monthly installments of Fixed Minimum Rent, shall be
paid in advance on the first day of each and every calendar month, and, together
with all other amounts payable by Tenant to Landlord hereunder, shall be paid at
the offices of Landlord set forth above, or at such other place or to such other
entity or entities as Landlord may from time to time designate by notice to
Tenant, without notice or demand therefor and without deduction, abatement or
set-off except as herein permitted.

          3.2  All costs, charges and expenses which Tenant is obligated to pay
to Landlord pursuant to the provisions of this Lease shall be deemed additional
rent ("Additional Rent"), and in the event of nonpayment thereof, after Tenant's
receipt of notice of nonpayment and the expiration of ten (10) days without
payment (provided that, if Tenant disputes in good faith its obligation to make
all or any portion of such payment, such ten (10) day period shall be extended
with respect to the disputed portion of such payment during the period of such
dispute), Landlord shall have all the rights and remedies with respect thereto
as is provided for herein or by applicable law in case of non-payment of rent
(Fixed Minimum Rent and Additional Rent are sometimes hereinafter collectively
referred to as "Rental").  If the Commencement Date shall be a date other than
the first day of a calendar month, the Fixed Minimum Rent and other charges
shall be prorated for the portion of the calendar month in which the
Commencement Date occurs, and shall be paid by Tenant promptly after being
billed therefor.

                                       5
<PAGE>
 
          Tenant covenants to pay the Fixed Minimum Rent and Additional Rent as
in this Lease provided, when due, and in lawful money of the United States which
shall be legal tender for payment of all debts and dues, public and private, at
the time of payment.  From and after the expiration of the applicable notice and
grace period provided in this Lease, all unpaid sums due and payable as Fixed
Minimum Rent and Additional Rent shall bear interest at the rate of two (2%)
percent per annum over the prime rate of interest announced, from time to time,
by The Chase Manhattan Bank, N.A., New York, New York, or any successor thereto,
to corporate borrowers of the highest credit standing for 90-day unsecured
commercial loans, but in no event more than the maximum permitted by law
(hereinafter referred to as the "Default Charge"), and such interest shall be
deemed to be Additional Rent; provided, however, that no further interest shall
be payable upon such interest.

          3.3  If at any time or times during the Term, the Fixed Minimum Rent,
Additional Rent or other charges payable by Tenant hereunder shall not be fully
collectible by reason of any Laws and Ordinances (including, without limitation,
rent control or stabilization laws), then for the period prescribed by such Laws
and Ordinances, Tenant shall pay to Landlord the maximum amounts permitted
pursuant thereto.  Upon the expiration of the applicable period of time during
which such amounts shall be uncollectible, Tenant shall pay to Landlord as
Additional Rent, within fifteen (15) days after demand, all such uncollected
amounts that would have been payable for the period absent such legal
restrictions; provided, however, that the retroactive collection thereof shall
then be lawful.

          Tenant shall remain obligated under this Lease in accordance with its
terms and shall not take any action to terminate, rescind or avoid this Lease,
notwithstanding any bankruptcy, insolvency, reorganization, liquidation,
dissolution or other proceeding affecting Landlord or any assignee of Landlord
or any action with respect to this Lease which may be taken by any trustee,
receiver or liquidator or by any court.

          4.1  Tenant initially shall use:  (i) the Building for administrative,
executive and general business offices, warehousing of finished goods, raw
materials and packaging components, and distribution, in the conduct of its
pharmaceutical business (the "Initial Building Use") and (ii) the Land, other
than that occupied by the Building, for parking and landscaping as shown on the
final approved site plan; and thereafter the Demised Premises may be used for
any lawful purposes, which are not prohibited by the Permitted Encumbrances and
the other provisions of this Lease (a "Subsequent Building Use").

          4.2  Tenant shall not suffer or permit the Demised Premises or any
part thereof to be used in any manner, or anything to be brought into or kept
therein, which would in any way:  (i) cause structural injury to the Building or
any part thereof; (ii) constitute a public or private nuisance; (iii) impair the
appearance, character or reputation of the Building and/or the Park; or (iv)
violate any of Tenant's other obligations under this Lease.

          4.3  For purposes hereof the term "Insurance Companies and Boards"
shall mean the companies writing the insurance policies required pursuant to the
provisions of this Lease and the New York Board of Fire Underwriters, or any
other body having similar jurisdiction and any body establishing insurance
premium rates.

                             COMPLIANCE WITH LAWS
                             --------------------

          5.1  A.  Landlord agrees that Landlord's Work in constructing the
Demised Premises shall comply with all Laws and Ordinances on the Commencement
Date and shall permit Tenant's initial use of the Demised Premises.

               B.  Landlord shall, at its sole cost and expense, comply with all
present and future laws, orders, ordinances and regulations, including, without
limitation, all environmental, health and safety laws and regulations, of all
state, federal, municipal and local governments, departments, commissions and
orders of any public officer pursuant to law, all orders, rules and regulations
of the Board of Fire Underwriters or a similar body ("Laws and Ordinances") and
all requirements of Insurance Companies and Boards applicable to the Building or
the Demised Premises (other than matters for which Tenant is responsible under
the provisions of this Section). Tenant shall, at its sole cost and expense,
comply with all Laws and Ordinances and all requirements of applicable Insurance
Companies and Boards to the extent that such compliance is necessitated by
reason of Tenant's Specific Use (as hereinafter defined) of the Demised
Premises. Anything in this Lease to the contrary notwithstanding, it is hereby
understood and agreed that compliance with Laws and Ordinances: (i) which are of
general applicability to office buildings, warehouses and distribution
facilities, and (ii) which do not arise as a result of Tenant's Specific Use,
shall not be the responsibility of Tenant. For purposes hereof, "Tenant's
Specific Use" shall mean (i) the specific nature of the Initial Building Use of
the Demised Premises by Tenant, (ii) the specific nature of a Subsequent
Building Use of the Demised Premises by Tenant and (iii) the conversion of the
Building from its then existing use to a Subsequent Building Use.

               C.  If any structural repair or alteration to the Demised
Premises or the Building shall be required under this

                                       7
<PAGE>
 
Article 5 and Tenant shall not be obligated to make the same pursuant to the
provisions hereof, such repair or alteration shall be made by Landlord, at
Landlord's sole cost and expense and in such manner so as to not unreasonably
interfere with Tenant's business or reduce the amount of useable space available
to Tenant.

               D.  In the event that Landlord pays the cost of any capital
expenditure required to be paid by Landlord by reason of any Laws and Ordinances
or the requirements of applicable Insurance Companies and Boards which become
effective after the Commencement Date, then Tenant shall pay to Landlord on the
first day of each calendar month during the period commencing with the calendar
month following completion of such capital expenditure and ending on the earlier
the expiration (inclusive of any Extended Terms elected by Tenant pursuant to
Article 33 below) or earlier termination of this Lease and the date upon which
such capital expenditure has been fully reimbursed by Tenant to Landlord, an
amount equal to the cost of such capital expenditure divided by the number of
months of the useful economic life of such capital expenditure.

          5.2  Landlord agrees to remedy, at Landlord's sole cost and expense,
all environmental problems, other than those caused by Tenant, and shall
indemnify, defend and hold Tenant harmless against all loss, liability, damages,
costs and expenses, including reasonable attorneys' fees, relating to any
Hazardous Materials, as hereinafter defined, found in the Demised Premises
during the term of this Lease that are not caused by Tenant. Tenant shall be
responsible to remedy, at its sole cost and expense, all environmental problems
caused by Tenant during the Term, and shall indemnify, defend and hold Landlord
harmless against all losses, liability, damages, costs and expenses, including
reasonable attorneys' fees, relating to any Hazardous Materials found in the
Demised Premises during the term of this Lease that are caused by Tenant.
Without limiting the generality of the provisions of Section 5.lB, Tenant agrees
not to use, generate, manufacture, produce, store, release, discharge or dispose
of (or permit any of the same) or permit to exist on the Demised Premises or
transport (or permit to be transported) to or from the Demised Premises any
hazardous substances, hazardous materials, toxic substances or solid waste as
defined in the Clear Air Act, the Comprehensive Environmental Response
Compensation and Liability Act ("CERCLA"), the Resource Conservation and
Recovery Act ("RCRA") and the Hazardous Materials Transportation Act ("HMTA"),
any substances or materials listed as hazardous or toxic in the United States
Department of Transportation Table, by the Environmental Protection Agency or
any successor agency or under any federal, state or local laws or regulations
(collectively, "Hazardous Materials"), except in the ordinary course of its
business and in compliance with all Laws and Ordinances, including, without
limitation, the Clean Air Act, CERCLA, RCRA and HMTA.  Tenant

                                       8
<PAGE>
 
will immediately remove or cause to be removed from the Demised Premises any
Hazardous Materials not used, stored, generated, manufactured, produced,
released or discharged in the ordinary course of its business.  Landlord
expressly acknowledges that Tenant shall from time to time, in the ordinary
course of its business, cause certain Hazardous Materials to be stored or
otherwise be present in the Demised Premises and agrees that such storage or
presence of Hazardous Materials shall be permitted by the terms of this Lease
provided Tenant complies with all applicable Laws and Ordinances relating
thereto.

          In the event any Laws and Ordinances, as applied to Tenant's Specific
Use, shall require Tenant to follow special procedures for such emissions or
discharges, whether into the atmosphere, the ground, the water systems and/or
the sewage system, including but not limited to, the pretreatment of sewage
and/or the installation of a monitoring well(s), Tenant shall be responsible for
full compliance therewith and all of the costs and expenses thereof.  Landlord
hereby covenants to cooperate with Tenant, to the extent necessary to enable
Tenant to comply with such procedures.  Tenant agrees to deliver to Landlord any
and all certifications, affidavits and other documents which may be required
pursuant to Laws and Ordinances during the Term and after the expiration of the
Term, indicating compliance by Tenant with the provisions thereof.  Without
limiting the generality of the foregoing, Tenant shall not intentionally
discharge into the sewer systems any Hazardous Materials stored in containers
situated in the Demised Premises.

          5.3  If Tenant receives written notice of any violation of any Laws
and Ordinances applicable to the Demised Premises, or any recommendations by any
Insurance Companies and Boards, Tenant shall give prompt notice thereof to
Landlord.

          5.4  Tenant, after notice to Landlord, may contest by appropriate
legal proceedings, without cost or expense to Landlord, the validity of any Law
or Ordinance, and may defer compliance therewith; provided, however, that (a)
such noncompliance shall not constitute a crime on the part of Landlord;
(b) Tenant shall diligently prosecute such contest to a final determination by a
court, department or governmental authority or body having final jurisdiction;
(c) Tenant shall indemnify Landlord against any and all liability, loss and
damage which Landlord may sustain by reason of Tenant's failure or delay in
complying therewith; and (d) Tenant shall keep Landlord advised as to the status
of such proceeding.  Landlord agrees to cooperate reasonably with Tenant, and to
execute any documents or pleadings reasonably required for the purpose of any
such contest; provided, however, that the same shall be without cost or expense
to Landlord.  Provided that Tenant chooses not to initiate a contest pursuant to
this paragraph, Landlord shall have the right, but not the obligation, to
contest by appropriate

                                       9
<PAGE>
 
legal proceedings, at Landlord's expense, any such Law or Ordinance.

          5.5  Tenant shall, at its own cost and expense, keep in full force and
effect any and all necessary permits, licenses, certificates or other
authorizations required in connection with Tenant's lawful and proper use,
occupancy, operation and management of the Demised Premises, and Tenant shall
obtain any and all necessary permits, licenses, certificates or other
authorization required in connection with Tenant's Specific Use of the Demised
Premises, provided however that nothing in this Section 5.5 shall increase,
enlarge or otherwise affect Tenant's obligations under Section 5.1 above.

          5.6  Subject to the provisions of Articles 8, 12 and 17 of this Lease,
no abatement, diminution or reduction of the Fixed Minimum Rent, or of any
Additional Rent or other charges required to be paid by Tenant pursuant to the
terms of this Lease, shall be claimed by, or allowed to, Tenant for any
inconvenience, interruption, cessation or loss of business or otherwise caused
directly or indirectly by any present or future Laws and Ordinances, or by
priorities, rationing or curtailment of labor or materials, or because of civil
commotion, strikes or riots, or any matter or thing resulting therefrom, nor
shall this Lease be affected by any such causes, except for any act, omission or
gross negligence of Landlord; provided, however, that Tenant shall in no event
have any right of offset against the Rental under this Lease, except as provided
in Section 17.2 hereof. Tenant however, may bring a separate action against
Landlord, subject to the limitations set forth in Article 27 hereof, and
provided further that nothing herein contained is intended to affect the
coverage of Landlord as additional insured under the policies of liability
insurance to be maintained by Tenant.

                          --------------------------

          6.1  Except with respect to replacements, repairs and restorations
which are the obligation of Landlord pursuant to an express provision of this
Lease, including without limitation Section 6.2 and Articles 5, 8 and 12 hereof,
Tenant shall, throughout the Term and at no expense whatsoever to Landlord, take
good care of the Demised Premises and shall not do or suffer any waste with
respect thereto, and Tenant shall promptly make all repairs and replacements to
the Demised Premises necessary to keep the Demised Premises (including the
heating, plumbing, electrical, ventilating and air-conditioning systems) in good
and lawful order and condition, ordinary wear and tear excepted. Tenant shall
keep and maintain all exterior areas of the Demised Premises in a clean and
orderly condition, reasonably free of accumulation of ice, snow, dirt and
rubbish.  Tenant agrees to use chemicals for de-icing which are not harmful to
the Demised

                                       10
<PAGE>
 
Premises.  Tenant agrees not to place a load upon any floor of the Building
which exceeds the load per square foot which such floor was designed to carry
and which is allowed by law.

          6.2  Anything to the contrary set forth in this Lease notwithstanding,
during the Term of this Lease and any renewals thereof, Landlord shall, upon
reasonable notice from Tenant, make all necessary structural repairs to the
Building (but excluding the exterior and interior of all windows, doors, plate
glass and signs) and all repairs to the roads and drives located on, or
providing access to, the Demised Premises which roads and drives are owned by
Landlord.  In addition, (i) during the first five (5) years and the last two (2)
years of the Term, Landlord agrees to make all replacements and repairs to the
heating, plumbing, electrical, ventilating and air conditioning systems (other
than such routine repairs as are necessary, in the course of Tenant's
maintenance of such systems, to keep such systems in good order and condition)
and (ii) during the first five (5) years of the Term, Landlord agrees to make
all replacements and repairs to the parking areas located on the Demised
Premises.  Tenant shall be responsible for the restriping of the parking lots
throughout the Term.

          Landlord shall not be required to do any of the work or supply any of
the materials required pursuant to this Section 6.2 in the event any damage is
caused by gross negligence of Tenant or Person Within Tenant's Control (as
hereinafter defined).

          6.3  Tenant shall promptly reimburse Landlord for expenditures made by
Landlord pursuant to Section 6.2 above during the last two (2) years of the
Initial Term or any Extended Term if (i) Landlord's obligation to make such
expenditures arises only during the last two (2) years of the Term and (ii)
Tenant thereafter exercises its option to extend the Term.

                                   INSURANCE
                                   ---------

          7.1  (a)  Tenant, at Tenant's cost and expense, will maintain
insurance on the Demised Premises as follows:

                 (i)   Insurance on an all-risk form insuring against the perils
of fire and extended coverage and physical loss or damage, including, without
duplication of coverage, theft, vandalism, malicious mischief, collapse, false
work, temporary buildings and debris removal, in amounts sufficient to prevent
Mortgagee, Landlord or Tenant from becoming a co-insurer of any loss, but in any
event in amounts not less than the actual replacement value of the Demised
Premises, exclusive of foundations, footings and excavations. The policies to be
provided pursuant to this Section 7.l(a)(i) shall be subject to such deductibles
as Tenant may elect, provided that, in the event of a loss covered by any such
policy, Tenant shall be obligated

                                       11
<PAGE>
 
to provide from its own funds a sum equal to the amount of such deductible
(which sum to be provided by Tenant shall, for purposes of Article 8 hereof, be
deemed "insurance proceeds").

          The actual replacement value of the Demised Premises shall be
determined from time to time, but not more often than once in every two (2)
years, at Landlord's request, by an appraiser designated by an insurer of the
Demised Premises and if the insurance company does not so designate an
appraiser, then by an appraiser designated by Landlord, at Landlord's cost and
expense, except that no such appraisal shall be required for the first two (2)
years of the Term.  Appraisals which are requested by the insurer shall be
conducted at the expense of the insurer or Tenant.  Notwithstanding the
foregoing provisions of this Section 7.1(a)(i), no appraisals of the Demised
Premises shall be required by Landlord as long as coverage of at least $30
million is provided with respect to the Demised Premises (by Tenant's blanket or
excess coverage policies, or otherwise).

                 (ii)  Rent insurance with the standard extended coverage
endorsements issued in connection with fire insurance policies covering property
similar to the Demised Premises in an amount equal to the aggregate of the Fixed
Minimum Rent, Impositions (as hereinafter defined) and all other charges payable
by Tenant pursuant to this Lease for a period of one (1) year, except that
Tenant may at its election provide such insurance by an appropriate endorsement
to its business interruption policy.

                 (iii) General comprehensive public liability insurance with
respect to the Demised Premises and its appurtenances in the combined aggregate
amount of not less than Five Million ($5,000,000.00) Dollars with respect to
death and/or injuries suffered in any one accident, including property damage.
Such limits shall be increased from time to time (but not more often than once
every five (5) years) as may be reasonably required by Landlord based upon the
limits which are customary for similar buildings in the general vicinity of the
Building.

                 (iv)  Workers' compensation insurance to the extent required by
the law of the State in which the Demised Premises are located and to the extent
necessary to protect Landlord and the Demised Premises against Workers'
compensation claims.

                 (v)   Such other insurance reasonably requested by Landlord, in
such amounts and against such risks, as is commonly obtained in the case of
property similar in use to the Demised Premises and located in the vicinity of
the Demised Premises are located, with due regard to the height and the type of
the Building, its construction, use and occupancy.

          The insurance described in this Section 7.1(a) shall be written by
companies of nationally recognized good financial standing legally qualified to
issue such insurance and shall name Tenant as insured party and Mortgagee and
Landlord as additional insureds, as their interests may appear.

          (b)  Every such policy (other than any comprehensive liability or
workers' compensation policy) shall bear a mortgagee endorsement in favor of
Mortgagee; and such policies shall provide that the loss, if any, shall be
adjusted and payable to Landlord to be held and applied by Landlord or Mortgagee
for reconstruction of the Demised Premises.  Every policy referred to in this
section (other than the workers' compensation policy) shall not be canceled or
materially altered except after 30 days' written notice to Landlord and the
Mortgagee and the policies referred to in Section 7.1(a)(i) and (ii) shall not
be invalidated by any act or neglect of Landlord or Tenant, nor by occupancy of
the Demised Premises for purposes more hazardous than permitted by such policy,
nor by any foreclosure or other proceedings relating to the Demised Premises,
nor by change in title to the Demised Premises.  Tenant will immediately deliver
to the Landlord copies of any notices of cancellation received with regard to
any insurance maintained pursuant to this Article.

          (c)  Tenant shall deliver to Landlord and Mortgagee original
certificates which set forth the major policy provisions and limits of liability
relating to the Demised Premises (together with such other reasonable
information as may be requested by Landlord or Mortgagee to correctly evidence
the insurance coverage of Tenant covering the Demised Premises) of insurers,
reasonably satisfactory to Mortgagee, evidencing the existence of all insurance
which is required to be maintained by Tenant hereunder, such delivery to be made
(i) promptly after the execution and delivery hereof, and (ii) within ten (10)
days prior to the expiration of any such insurance.  Tenant shall have the right
to pay such premiums in installments.  Tenant shall not obtain or carry separate
insurance concurrent in form or contributing in the event of loss with that
required by this Article.  Any insurance required hereunder may be provided
under blanket policies or excess coverage (umbrella) policies, provided that the
policies otherwise comply with the provisions of this Lease and allocate to the
Demised Premises the specific coverage, without possibility of reduction or
coinsurance by reason of, or damage to, any other property named therein.

          7.2  Each insurance policy insuring the Demised Premises and Tenant's
fixtures and contents against loss, shall be written in a manner so as to
provide that the insurance company waives all right of recovery by way of
subrogation against Landlord and Mortgagee in connection with any loss or damage
covered by any such policies, provided that such waiver is available at no
additional cost to Tenant.  If an additional charge is imposed to obtain such
waiver, Landlord may elect to

                                       13
<PAGE>
 
pay such charge.  Landlord and Mortgagee shall not be liable to Tenant, to the
extent of the insurance proceeds actually collected and retained by Tenant, for
any loss or damage caused by fire or any of the risks enumerated in such
policies provided such waiver was in effect with respect to such policies at the
time of such loss or damage.  If the release of either Landlord or Mortgagee
shall contravene the provisions of any insurance policy or any law with respect
to exculpatory agreements, the liability of the party in question shall be
deemed not released but no action or rights shall be sought or enforced against
such party unless and until all rights and remedies against such party's insurer
are exhausted and such party shall be unable to collect such insurance proceeds.

                            FIRE AND OTHER CASUALTY
                            -----------------------

          8.1  (a)  Subject to the provisions of Section 8.1(b), Section 8.2,
Section 8.3 and Section 8.4 hereof, if the Building or the Demised Premises
shall be damaged by any casualty, Tenant shall notify Landlord of the same and
if an election to terminate this Lease shall not have been made pursuant to this
Article 8, Landlord shall repair said damage and restore and rebuild the
Building and/or Demised Premises (excluding Tenant Work and the personal
property of Tenant). In such event, the Fixed Minimum Rent payable hereunder
shall be reduced, until such time as the repair and restoration work is
Substantially Completed, Tenant has had an opportunity to Substantially Complete
restoration of Tenant's Work, and Tenant is not prevented by the condition of
the Demised Premises from occupying the Demised Premises for the normal conduct
of its business, in proportion to the extent that the Demised Premises are
rendered unusable for the normal conduct of the business then conducted on the
Demised Premises, and Landlord shall be entitled to receive the proceeds of rent
insurance maintained pursuant to Section 7.1(a)(ii) hereof. Such repair and
restoration work shall be diligently commenced and prosecuted by Landlord until
full completion thereof. It is acknowledged that a casualty affecting a portion
of the Warehouse (as hereinafter defined) may, as a consequence of Tenant's
Specific Use thereof, render the entire Warehouse unusable for the normal
conduct of the business conducted therein by Tenant. The terms of the rent
insurance maintained pursuant to Section 7.1(a)(ii) hereby shall acknowledge
the foregoing.

          (b)  If the insurance proceeds available to Landlord (or Landlord's
mortgagee) are not adequate to pay for the full cost of such repair and
restoration work, then (i) Landlord shall not be obligated to pay such
deficiency if within thirty (30) days of the date of such casualty, Landlord
sends written notice to Tenant (the "Insurance Deficiency Notice") advising
Tenant of the amount of such deficiency and that Landlord elects not to pay such
deficiency, and (ii) in the event that Landlord delivers the Insurance
Deficiency Notice to Tenant within such thirty (30) day

                                       14

period, Tenant shall have the right, at its option, to terminate this Lease by
sending written notice of such termination to Landlord within ninety (90) days
after Tenant's receipt of the Insurance Deficiency Notice, which termination
shall be effective as of any date designated by Tenant, which effective date
shall not be more than twelve (12) months from the date of such termination
notice, or if Tenant does not terminate this Lease as aforesaid, Tenant shall
pay such deficiency.  Notwithstanding the preceding sentence, Tenant shall pay
any deficiency attributable to Tenant's failure to maintain in effect any
insurance required to be maintained by Tenant pursuant to this Lease, and, in
such event, Tenant shall not have the right to terminate this Lease (it being
understood that Tenant shall not be responsible for any deficiency that would
not have been paid pursuant to normal policy exclusions).  Landlord shall apply
all insurance proceeds received with respect to any insurance required to be
maintained by Tenant hereunder (other than the insurance to be provided pursuant
to Section 7.1(a) (ii) above) for the purposes of fully repairing and replacing
the damage unless an election to terminate this Lease is made pursuant to this
Article 8.

          8.2  If the Building and/or Demised Premises shall be damaged by
casualty, to the extent that the portion of the Demised Premises used by Tenant
as a warehouse and distribution facility (the "Warehouse") is rendered unusable
for the normal conduct of Tenant's business then conducted in the Warehouse, and
a reputable contractor selected by Landlord and reasonably approved by Tenant
estimates that the repair of the Warehouse (including Tenant's Work, but
excluding the personal property of Tenant) cannot be Substantially Completed
within seven (7) months after the date of such casualty, Tenant may terminate
this Lease by notice to Landlord given within sixty (60) days of the date of
such casualty.  Upon such notice, this Lease shall terminate (and Tenant shall
not be responsible for paying any deficiency pursuant to Section 8.1(b));
provided, however, that the provisions of this Lease which are designated to
cover matters of termination and the period thereafter shall survive the
termination of this Lease.  Landlord shall use reasonable efforts to cause such
contractor's estimate to be rendered and delivered to Tenant within thirty (30)
days after the casualty.

          8.3  If the Building and/or the Demised Premises shall be damaged by
casualty, to the extent that the portion of the Demised Premises used by Tenant
for office purposes (the "Offices") is rendered unusable for the normal conduct
of Tenant's business then conducted in the Offices, and a reputable contractor
selected by Landlord and reasonably approved by Tenant estimates that the repair
of the Offices (including the leasehold improvements, but excluding the personal
property of Tenant) cannot be Substantially Completed within twelve (12) months
after the date of such casualty, Tenant may terminate this Lease by notice to
Landlord given within sixty (60) days of the date of such casualty.  Upon such
notice this Lease shall terminate (and

                                       15
<PAGE>
 
Tenant shall not be responsible for paying any deficiency pursuant to Section
8.1(b)), provided, however, that the provisions of this Lease which are
designated to cover matters of termination and the period thereafter shall
survive the termination of this Lease.  Landlord shall use reasonable efforts to
cause such contractor's estimate to be rendered and delivered to Tenant within
thirty (30) days after the casualty. Notwithstanding the foregoing, Tenant shall
not have a right to terminate this Lease pursuant to this Section 8.3 in the
event that Landlord is able to provide to Tenant, within thirty (30) days of the
casualty and upon terms reasonably acceptable to Tenant, substitute office
facilities in the immediate vicinity of the Building, which are reasonable
acceptable to Tenant, and which will be available to Tenant during the period
that the repair and restoration work to the offices is being completed.

          8.4  If a casualty occurs during the last two (2) years of the Term
and if any portion of the Demised Premises shall be so damaged by such casualty
that the cost of repair or replacement would exceed twenty-five percent (25%) of
the replacement cost of the Building as estimated by a reputable contractor
selected by Landlord and reasonably approved by Tenant, Tenant may terminate
this Lease by notice to Landlord given within sixty (60) days of the date of
such casualty and upon such notice, this Lease shall terminate; provided,
however, that the provisions of this Lease which are designated to cover matters
of termination and the period thereafter shall survive the termination of this
Lease.  If Tenant does not choose to terminate this Lease in accordance with
this paragraph within such sixty (60) day period, Landlord may, at its option,
terminate this Lease by notice to Tenant given within ten (10) days of the
expiration of such sixty (60) day period.  Landlord shall use reasonable efforts
to cause such contractor's estimate to be rendered and delivered to Tenant
within thirty (30) days after the casualty.

          8.5  No damages, compensation, or claim shall be payable by Landlord
for inconvenience, loss of business or annoyance arising from any repair or
restoration of any portion of the Demised Premises, the leasehold improvements,
or the Building.  Landlord shall use reasonable efforts to have such repairs for
which it is responsible made promptly so as not to unnecessarily interfere with
Tenant's occupancy.

          8.6  In the event of the termination of this Lease pursuant to the
provisions of Section 8.1(b), Section 8.2, Section 8.3 or Section 8.4, this
Lease, the Term and the estate hereby granted shall expire as of the date of
such termination in the same manner and with the same effect as if it were the
date set for the normal expiration of the Term, and Fixed Minimum Rent shall be
apportioned as of the date of termination.

<PAGE>
 
          8.7  (a)  If any of the insurance monies paid to Landlord shall remain
after the completion of the repair and restoration, the excess shall be paid to
Tenant, or if Tenant and Landlord funded any deficiency in the insurance
proceeds in order to complete the repair and restoration work, any excess shall
be shared by Landlord and Tenant proportionately to the amount of the deficiency
contributed by each party.

          (b) Tenant understands that Landlord will not carry insurance of any
kind on Tenant's furniture or furnishings or on any fixtures or equipment
removable by Tenant under the provisions of this Lease, including Tenant's Work,
and that Landlord shall not be obligated to repair any damage thereto or replace
the same.

          8.8  Landlord and Tenant each agrees that it will cooperate with the
other, to such extent as such other party may reasonably require, in connection
with the prosecution or defense of any action or proceeding arising out of, or
for the collection of, any insurance monies that may be due in the event of any
loss or damage, and that they each will execute and deliver to the other party
such instruments as may be reasonably required to facilitate the recovery of any
insurance monies.

          8.9  Tenant agrees to give prompt notice to Landlord with respect to
all fires and other casualties occurring in, on, at or about the Demised
Premises.

                                   ---------

          9.1  After the Substantial Completion of Landlord's Work, Tenant
agrees that Landlord is not, nor shall it be, required to furnish to Tenant or
any other occupant of the Demised Premises any gas, water, sewer, electric, heat
or any other utility, facility, equipment, labor, materials, services or trash
removal of any kind whatsoever (collectively referred to in this Article as
"Utilities and Services").

          9.2  Tenant agrees to obtain all Utilities and Services and to pay all
charges therefor.  Provided that Landlord performs all of its obligations under
Article 6 in a timely manner, Tenant expressly agrees that Landlord shall not be
responsible for the failure of supply to Tenant of any of such Utilities and
Services, or any other utility or services, whether similar or dissimilar to
those enumerated in this Article.

           9.3  Tenant agrees to limit its consumption of water at the Demised
Premises to not more than l0~000 gallons per day.

          9.4  Notwithstanding the foregoing provisions of this Article 9, as
long as water and sewer service is provided to the Demised Premises by an
affiliate of Landlord, unless the water

                                       17
<PAGE>
 
and sewer rates are regulated by a state or municipal agency, Tenant's
obligation to pay for water and sewer service shall be limited to the amount
that is computed based upon the average rates approved by the state or municipal
agency then applicable to the provision of water to facilities comparable to the
Demised Premises in the vicinity thereof.

                                MECHANIC'S LIENS
                                ----------------

          10.1  Tenant shall not suffer or permit any liens to be filed against
the Park, Demised Premises or any part thereof or against Tenant's leasehold
estate therein by reason of any work, labor, services or materials done for, or
supplied, or claimed to have been done for, or supplied to, Tenant or any one
holding the Demised Premises or any part thereof through or under Tenant.  If
any such lien shall at any time be filed against the Park, the Demised Premises
or any part thereof or against Tenant's leasehold estate therein, Tenant shall
cause the same to be discharged of record within forty-five (45) days after the
date of notice thereof to Tenant, by either payment, deposit, bond or otherwise.
If Tenant shall fail to discharge any such lien within such period, then, in
addition to any other right or remedy of Landlord, Landlord may, but shall not
be obligated to, procure the discharge of the same either by paying the amount
claimed to be due by deposit in court or by bonding, and/or Landlord shall be
entitled, if Landlord so elects, to compel the prosecution of an action for the
foreclosure of such lien by the lienor and to pay the amount of the judgment, if
any, in favor of the lienor with interest, costs and allowances.  Any amount
paid or deposited by Landlord for any of the aforesaid purposes, and all legal
and other expenses of Landlord, including reasonable attorneys' fees, in
defending any such action or in or about procuring the discharge of such lien,
with all necessary disbursements in connection therewith, together with the
Default Charge thereon, shall become due and payable forthwith by Tenant to
Landlord.

          10.2  Nothing in this Lease shall be deemed to be, or construed in any
way as constituting, the consent or request of Landlord, expressed or implied,
by inference or otherwise, to any person, firm or corporation for the
performance of any labor or the furnishing of any materials for any
construction, rebuilding, alteration or repair of or to the Demised Premises or
any part thereof, nor as giving Tenant any right, power or authority to contract
for or permit the rendering of any services or the furnishing of any materials
which might in any way give rise to the right to file any lien against
Landlord's interest in the Demised Premises.

                                  ALTERATIONS
                                  -----------

          11.1   For the purposes of this Article the term "Alterations" shall
include, without limitation, decorations, installations, changes, restorations,
replacements, additions, improvements and betterments.  An alteration shall be
deemed to be structural if it involves or affects (a) the exterior (or the
exterior appearance) of the Building other than landscaping or the restriping of
the parking areas located on the Demised Premises or the other areas of the
Demised Premises outside the Building other than landscaping or the restriping
of the parking areas located on the Demised Premises, or the roof or foundations
of the Building, (b) the supporting members or structural elements of the
Building, or (c) any of the Building systems in a material and adverse manner.

          After the completion of Tenant's Work, Tenant shall make no
Alterations in or to the Demised Premises, whether structural or non-structural,
without Landlord's prior written consent, except as follows:

          (a) Tenant may make non-structural Alterations in each instance
costing less than Fifty Thousand ($50,000) Dollars and decorative Alterations
costing less than One Hundred Thousand ($100,000) Dollars without obtaining
Landlord's consent.

          (b) Landlord agrees that it shall not unreasonably withhold or delay
its consent to any other Alterations to the Demised Premises requested to be
made by Tenant.

          (c) No structural Alterations in or to the Demised Premises shall be
made by Tenant without obtaining Landlord's prior consent in each case, which
consent shall not be unreasonably withheld or delayed.

          All Alterations: (i) shall be done at Tenant's sole expense; (ii) may
be made at all hours and days; (iii) shall in all events comply with all Laws
and Ordinances and all orders, rules and regulations of Insurance Boards; (iv)
shall be made in a good workmanlike manner using materials comparable in quality
to the quality of the existing materials in the Demised Premises; and (v) shall,
in the case of structural Alterations, non-structural Alterations costing in
excess of Fifty Thousand ($50,000) Dollars and decorative Alterations costing in
excess of One Hundred Thousand ($100,000) Dollars, be made only by contractors
or mechanics approved by Landlord (which approval Landlord agrees not to
unreasonably withhold or delay).

          11.2  Prior to commencing any Alterations, Tenant shall furnish to
Landlord, and obtain Landlord's prior written consent (unless said consent is
not required pursuant to subparagraph (a) of Section 11.1) to:

                                       19
<PAGE>
 
                 (i)    Plans and specifications (to be prepared by and at the
expense of Tenant), in detail, of such proposed Alterations, and Landlord agrees
that provided Tenant otherwise complies with the provisions of this Article 11,
Landlord shall not unreasonably withhold or delay its consent to plans and
specifications in connection with Alterations, provided that Tenant shall not be
obligated to provide such plans and specifications for non-structural
Alterations costing less than Fifty Thousand ($50,000) Dollars, or decorative
Alterations costing less than One Hundred Thousand ($100,000) Dollars;

                 (ii)   A certificate evidencing that Tenant (or Tenant's
contractors) has (have) procured and paid for workmen's compensation and
employer liability insurance covering all persons employed in connection with
the work who might assert claims for death or bodily injury against Landlord,
Tenant, the Land or the Building;

                 (iii)  Such additional personal injury and property damage
insurance (over and above the insurance required to be carried by Tenant
pursuant to the provisions of Article 7) and builder's risk fire and other
casualty insurance as Landlord may reasonably require in connection with the
work to be done by Tenant; and

                 (iv)   Such permits, authorizations or consents as may be
required by any applicable Law or Ordinance, all of which shall be obtained at
Tenant's expense; provided, however, that no plans, specifications or
applications shall be filed by Tenant with any governmental authority without
first obtaining Landlord's consent (which Landlord agrees not to unreasonably
withhold or delay to the extent provided elsewhere in this Article), except to
the extent authorized under subparagraph (a) of Section 11.1. Landlord agrees to
cooperate with Tenant's efforts to obtain such permits, authorizations and
consents. Without limiting the generality of the foregoing, Landlord shall
execute and deliver and/or join in the execution and delivery of any building or
alteration permit applicable requested by Tenant.

           11.3  (Except for the property described in Section 11.5 which Tenant
may remove at the end of the Term) in no event shall any material or equipment
be incorporated in the Demised Premises in connection with any such Alteration
which is subject to any lien, encumbrance, chattel mortgage, security interest,
charge of any kind whatsoever, or is subject to any conditional sale or other
similar or dissimilar title retention agreement.

          11.4   Upon the termination of this Lease, Tenant shall be required to
remove all Alterations with respect to which (i) Tenant was required to obtain
Landlord's consent pursuant to subparagraph (a) of Section 11.1 hereof, and (ii)
Landlord notified Tenant, at the time of Landlord's consent to the installation
of such Alteration, that Tenant would have to remove

                                       20
<PAGE>
 
the same from the Demised Premises at the termination of this Lease.

          11.5  Where furnished by or at the expense of Tenant (except where
same is a replacement of an item theretofore furnished and paid for by Landlord
or against which Tenant has received a credit), all movable property, furniture,
furnishings, trade fixtures and equipment (including such trade fixtures and
equipment which may be attached to the Building due to the nature of Tenant's
business) shall remain the property of Tenant, and may be removed by Tenant on
or before the expiration of the Term, and, in case of damage by reason of the
removal, Tenant shall restore the Demised Premises to good order and condition,
normal wear and tear excepted. If Tenant shall fail to remove such property,
Landlord may remove such property, and dispose of it or place it in storage. Any
of such property not removed by Tenant shall, at the election of Landlord, be
deemed to be abandoned by Tenant, and Landlord may return or dispose of such
property as Landlord shall elect, without any liability to Tenant.

          11.6  Except as provided in Sections 11.4 and 11.5, all of Landlord's
Work and all of Tenant's Work shall become the property of Landlord and shall
remain upon, and be surrendered with, said Demised Premises, as a part thereof,
at the end of the Term. Except as provided in Sections 11.4 and 11.5, all
Alterations upon the Demised Premises, made by either party subsequent to
Landlord's Work and Tenant's Work, affixed to the realty shall become the
property of Landlord and shall remain upon, and be surrendered with, said
Demised Premises, as a part thereof, at the end of the Term. Except as provided
in Sections 11.4 and 11.5, in no event shall Tenant be required or permitted to
remove (a) the original installations made by Landlord as part of Landlord's
Work or Tenant as part of Tenant's Work, or (b) Alterations, made by Tenant. Any
Alteration which is not removed by Tenant from the Building at the end of the
Term shall be deemed abandoned by Tenant to Landlord, and Landlord may remove
the same from the Demised Premises.

                                  ------------

          12.1  In the event that all of the Demised Premises are taken or
condemned for any public purpose, this Lease shall terminate as of the date of
such taking; provided, however, that those provisions of this Lease which are
designated to cover matters of termination and the period thereafter shall
survive the termination hereof.

          12.2  In the event that any portion of the Warehouse or more than
twenty percent (20%) of the Offices shall be taken or condemned for any public
purposes, or in the event of any taking or condemnation which prevents Tenant
from having access to any portion of the Warehouse or at least eighty percent
(80%) of the

                                       21
<PAGE>
 
Offices or which reduces the number of parking spaces available to Tenant below
ninety percent (90%) of the number of parking spaces available to Tenant
immediately prior to such taking or condemnation, then Tenant shall have the
option, exercisable within thirty (30) days after Tenant receives notice of such
taking or condemnation, to terminate this Lease effective as of the date
specified by Tenant in its notice of termination, which effective date shall not
be more than one (1) year after the date of Tenant's notice of termination;
provided, however, that those provisions of this Lease which are designated to
cover matters of termination and the period thereafter shall survive the
termination hereof; and provided further that Landlord may negate Tenant's
option to terminate this Lease pursuant to Section 12.2 by reason of any taking
of any portion of the Offices or any parking spaces if Landlord provides to
Tenant, in a location and condition satisfactory to Tenant, similar office space
of the same dimensions of those taken or condemned or an equal number of
substitute parking spaces in the immediate vicinity of the Building.

          12.3  In the event that a portion, but less than all, of the Demised
Premises shall be taken or condemned for any public purpose or such taking or
condemnation shall result in a denial of access to a portion, but less than all,
of the Demised Premises, then this Lease shall terminate as of the date of such
taking as to the portion of the Demised Premises so taken or denied access, and,
unless Tenant exercises its option to terminate this Lease pursuant to Section
12.2 hereof, this Lease shall remain in full force and effect as to the
remainder of the Premises.  In such event, the Fixed Minimum Rent will be
diminished by an amount representing the part thereof applicable to the portion
of the Demised Premise so taken, and Landlord shall restore the balance of the
Demised Premises to an architecturally complete unit with reasonable promptness.

          12.4  In the event of the termination of this Lease pursuant to the
provisions of Sections 12.1 and 12.2, the Lease shall expire as of the date of
such termination in the same manner and with the same effect as if that were the
date set for the normal expiration of the Term, and Fixed Minimum Rent shall be
apportioned as of the date of termination.  The provisions of this Section shall
apply in the same manner to any partial termination of this Lease pursuant to
the provisions of this Article 12.

          12.5  Landlord may appear in any condemnation proceeding or action or
taking to negotiate, prosecute and adjust any claim for an award thereunder.
Landlord shall be entitled to receive the entire award in any condemnation
proceeding or action for taking, without deduction therefrom for any estate
vested in Tenant by this Lease; provided that nothing herein contained shall
prohibit Tenant from seeking severance damages, moving

                                       22
<PAGE>
 
expenses or any other award so long as any such award does not reduce the award
payable to Landlord.

          12.6  If the temporary use or occupancy of all or any part of the
Demised Premises shall be condemned or taken for any public or quasi-public use
during the Term, this Lease shall be and remain unaffected by such condemnation
or taking and Tenant shall continue to pay the full Fixed Minimum Rent payable
hereunder and Tenant shall be entitled to receive the entire amount of any award
made for such taking, whether paid as damages, rent or otherwise, provided,
however, that in the event that: (i) any such temporary taking involves any
portion of the Warehouse or more than twenty percent (20%) of the Offices or
prevents Tenant from having access to any portion of the Warehouse or at least
eighty percent (80%) of the Offices or reduces the number of parking spaces
available to Tenant below ninety percent (90%) of the number of parking spaces
available to Tenant immediately prior to such taking, and (ii) such taking is
for a period of more than six (6) months, Tenant may elect to terminate this
Lease by notifying Landlord of such election within thirty (30) days after
Tenant receives notice of such taking, in which event this Lease shall terminate
as of the date specified in Tenant's notice of termination, which effective date
shall not be later than one (1) year after the date of Tenant's notice of
termination; provided, however, that the provisions of this Lease which are
designated to cover matters of termination and the period thereafter shall
survive the termination hereof. For purposes hereof, Offices and/or parking
spaces shall be deemed available to Tenant if alternative Offices and/or
substitute parking spaces are provided to Tenant in accordance with the
requirements of Section 12.2.

                           --------------------------

          13.1  Tenant shall permit Landlord and the authorized representatives
of Landlord, upon notice of not less than fifteen (15) days (except in
emergency), to enter the Demised Premises at all reasonable times during usual
business hours for the purpose of making any repairs required to be made by
Landlord to fulfill Landlord's obligations under this Lease, or inspecting the
Demised Premises, and after the notice and the expiration of the grace period
provided for in this Lease, for the purpose of curing any defaults on the part
of Tenant in the making of any necessary repairs to the Demised Premises, or in
the performance of any work therein that may be necessary to comply with any
Laws and Ordinances, or that may be necessary to prevent waste or deterioration
in connection with the Demised Premises.  No prior notice of such entry shall be
necessary in the case of emergency, but Landlord agrees to provide Tenant with
written notice of its entry as soon thereafter as practicable.  Nothing in this
section 13.1 shall imply any duty upon the part of Landlord to cure any such
defaults or to do any such work.  The performance thereof by

                                       23

Landlord shall not constitute a waiver of Tenant's default in failing to perform
the same.  Landlord shall be liable for all damage to Tenant's property caused
by Landlord or Landlord's agents or employees in connection with the making of
repairs or the performance of any work in the Demised Premises or on account of
bringing materials, supplies and equipment into or through the Demised Premises
during the course thereof.  Landlord must use its best efforts to minimize any
inconvenience or damage caused by Landlord in connection with the making of
repairs or performance of any work on the Demised Premises and to coordinate the
scheduling of such repairs, maintenance, or work with Tenant.

          For a period commencing six (6) months prior to the end of the Term,
Landlord shall have reasonable access to the Demised Premises for the purposes
of exhibiting the same to prospective tenants and for posting any "To Let" or
"To Lease" signs upon the Demised Premises.  The size and location of such signs
shall be subject to Tenant's approval, which approval may not be unreasonably
withheld.

                      ASSIGNMENT, SUBLETTING, MORTGAGING
                      ----------------------------------

          14.1  Tenant covenants and agrees that neither this Lease nor the Term
and estate hereby granted, nor any part hereof or thereof, will be assigned,
mortgaged, pledged, encumbered or otherwise transferred, by Tenant or by
operation of law or otherwise, and that neither the Demised Premises, nor any
part thereof, will be sublet or occupied, by anyone other than Tenant, or for
any purpose other than as set forth in this Lease, without the prior written
consent of Landlord in every case, except as expressly provided in subparagraph
(c) hereinbelow.

          Notwithstanding the foregoing provisions of this Section 14.1:

          (a) Prior to the agreement by Tenant to any assignment or subletting,
Tenant shall submit to Landlord in writing: (1) the name of the proposed
assignee or subtenant; (2) a copy of the proposed written agreement including
all of the terms and conditions of the proposed assignment or subletting,
stating that such agreement shall not become effective unless Landlord hereunder
shall consent thereto in writing and which shall contain a provision complying
with Section 14.4; (3) the nature and character of the business of the proposed
assignee or subtenant and any other information reasonably requested by
Landlord; (4) a financial statement of the proposed assignee or subtenant,
certified to by a certified public accountant as of a date not more than twelve
(12) months prior thereto or if not available, such other financial information
as may be reasonably acceptable to Landlord; and (5) an agreement by Tenant to
indemnify, defend and hold Landlord harmless against any claim or liability for
real estate brokerage commission payable with

                                       24
<PAGE>
 
respect to any sublease or assignment by Tenant in accordance with this Article.

          Provided Tenant is not in default hereunder (after notice from
Landlord if any be required hereunder and the expiration of any applicable grace
period)1 Landlord's consent to any such proposed assignment or subletting shall
not be "unreasonably" withheld or delayed, in accordance with paragraph (b).
This paragraph (a) shall apply to each and every proposed assignment and
sublease during the Term hereof, and if Tenant fails to consummate any proposed
assignment or sublease to which Landlord shall have consented within one hundred
eighty (180) days after granting such consent, this paragraph (a) shall again
apply to said proposed assignment or sublease.

          (b)   In determining reasonableness, Landlord may take into
consideration all relevant factors surrounding the proposed sublease or
assignment, including, without limitation, the following:

                (i)      the financial stability and business reputation of the
proposed assignee or subtenant;

                (ii)     the nature of the business and the proposed use of the
Demised Premises by the proposed assignee or subtenant in relation to the
majority of other tenants in the Park;

                (iii)    the proposed assignee or subtenant shall not be a
tenant of other space in the Park, and shall not be entitled directly or
indirectly to diplomatic or sovereign immunity; and

                (iv)     not more than two (2) unrelated entities shall occupy
the Demised Premises at any time.

          (c)   Notwithstanding any contrary provision of this Lease, provided
Tenant shall not be in default hereunder (which continues after notice and the
expiration of any applicable grace period), this Lease may be assigned at any
time without the consent of Landlord, to any corporation into which or with
which Tenant may be merged or consolidated, or to any corporation which shall
purchase all or substantially all of the assets of Tenant, or assigned or sublet
in whole or in part to any subsidiary or affiliate of Tenant, provided each of
the following conditions shall be complied with:

                (i)     If such assignment shall be to a successor by merger or
consolidation, or by acquisition of assets, such successor shall have acquired
all or substantially all of the assets of the assignor;

                                       25
<PAGE>
 
                (ii)    If such assignment or sublease shall be to a subsidiary
or affiliate, such subsidiary or affiliate shall have assumed all of the
liabilities hereunder of the assignor, and the assignor shall have expressly
agreed to continue to remain jointly and severally liable as Tenant hereunder;

                (iii)   The assumptions and agreement referred to in
subparagraphs (i) and (ii) above, shall be set forth in written instruments
complying with the provisions of Section 14.4 of this Lease; and

                 (iv)   The assignee or sublessee shall at all times use the
Demised Premises for a purpose permitted by Article 4 hereof; and

                  (v)   Subdivision (iv) of paragraph (b) above shall apply.

          For the purposes of this paragraph, a corporation shall be deemed to
be a subsidiary of Tenant if fifty (50%) percent or more of its voting stock
shall be owned by Tenant, and a corporation or other person or entity shall be
deemed to be an affiliate of Tenant if it directly or indirectly controls, is
controlled by or is under common control with Tenant.

          (d)  Notwithstanding the provisions of subparagraphs (b) and (c)
above, Tenant shall obtain, at Tenant's cost and expense, all necessary
governmental consents and approvals for the occupancy of the Demised Premises,
or any portion thereof, by such permitted assignee or sublessee.

          (e)  In the event of the sale or other disposition of all or
substantially all of the assets of Tenant during the Term of this Lease, the
transferee of assets shall be deemed to have assumed all obligations, covenants
and responsibilities of Tenant under this Lease.  Upon request of Landlord, the
transferee of assets shall deliver to Landlord an instrument in recordable form
evidencing the aforesaid assumption of this Lease.

          14.2  If this Lease is assigned or if the Demised Premises is sublet
or occupied by anyone other than Tenant, and if Tenant is in default (after
notice from Landlord if any be required hereunder and the expiration of any
applicable grace period), Landlord may collect Fixed Minimum Rent, Additional
Rent and other charges from the assignee, sublessee or occupant, and apply the
net amount collected to the Fixed Minimum Rent, Additional Rent and other
charges herein provided, but no such assignment, subletting, occupancy or
collection shall be deemed a waiver of the covenant by Tenant under Section
14.1, nor shall the same be deemed the acceptance of the assignee, sublessee or
occupant as a tenant, or a release of Tenant from the further performance of the
covenants and agreements contained in this Lease on the part of Tenant to be
performed.

<PAGE>
 
          14.3  The consent by Landlord to an assignment or subletting shall not
relieve Tenant, the assignee or subtenant from obtaining the express consent in
writing of Landlord to any further assignment or subletting required pursuant to
this Article 14.

          14.4  Each permitted assignee or transferee of this Lease shall assume
and be deemed to have assumed this Lease and shall be and remain liable jointly
and severally with Tenant for the payment of the Fixed Minimum Rent, Additional
Rent and other charges, and for the due performance of and compliance with all
of the terms, covenants, conditions and agreements contained in this Lease on
Tenant's part to be performed or complied with for the Term.  No assignment,
sublease or transfer shall be binding on Landlord unless such assignee,
subtenant or transferee of Tenant shall deliver to Landlord a duplicate original
of the instrument of assignment, sublease or transfer which (i) contains a
covenant of assumption by the assignee or transferee (other than a subtenant) of
all of the obligations aforesaid, (ii) contains a confirmation that Landlord
shall have all of the rights set forth in this Article as to any further
assignment or subletting superior to and preemptive of any rights of sublessor
thereunder, and (iii) in every case, other than pursuant to Section 14.1(c)
hereof Landlord shall have consented thereto in advance in writing as required
hereunder.  In the event of Tenant's failure to comply with the provisions of
this Article, Landlord may elect to treat such purported assignee, subtenant or
transferee as having assumed this Lease jointly and severally with Tenant,
without in any way or to any extent binding Landlord to consent to such
purported assignment, sublease or transfer.

          14.5  If Landlord shall for any reason or cause recover or come into
possession of said Demised Premises before the date hereinbefore fixed for the
expiration of the Term, Landlord shall have the right at its option to take over
any and all subleases or subletting of the Demised Premises or any part or parts
thereof made or granted by Tenant and to succeed to the rights and privileges of
Tenant with respect to said subleases and subletting or such of them as it may
elect to take over and assume, and Tenant hereby expressly assigns and transfers
to Landlord such of the subleases and subletting as Landlord may elect to take
over and assume at the time of such recovery of possession, and Tenant shall
upon request of Landlord execute, acknowledge and deliver to Landlord such
further assignments and transfers as may be necessary, sufficient and proper to
vest in Landlord the then existing subleases and subletting.  By its acceptance
of and entry- into a sublease, subtenant thereunder shall be deemed to have
thereby agreed that, at Landlord's election, such subtenant shall be bound to
Landlord for the balance of the term of such sublease and shall attorn to
Landlord, as its landlord, under all of the terms, covenants and conditions of
such Sublease.

                                  ---------- 

          15.1  Tenant shall not erect any signs on the Demised Premises without
Landlord's prior written consent, which consent Landlord agrees not to
unreasonably withhold.  All such signs must conform to all Laws and Ordinances.

                                  IMPOSITIONS
                                  -----------

          16.1  Tenant agrees to pay to the appropriate taxing authority, all
Impositions (as hereinafter defined) and to provide Landlord with proof of the
payment thereof upon Landlord's request.  Such Impositions shall be paid prior
to delinquency.  If, at Tenant's option, Tenant pays the Impositions to Landlord
rather than to the appropriate taxing authority, Landlord agrees to pay or cause
to be paid all such monies to the appropriate authorities prior to delinquency.

          16.2  As used herein the term "Impositions" shall mean: (a) all taxes,
assessments, levies, fees, water and sewer rents and charges, and all other
governmental charges, general and special, ordinary and extraordinary, and
whether or not the same shall have been within the express contemplation of the
parties hereto, together with any interest and penalties thereon, which are
imposed or levied upon or assessed against (i) all or any part of the Demised
Premises, (ii) the Fixed Minimum Rent, Additional Rent or other charges payable
by Tenant hereunder, or (iii) this Lease or the leasehold estate created hereby;
(b) any gross receipts, gross income, rental income or similar taxes which fail
to take into account deductions with respect to the Demised Premises such as
depreciation, interest, taxes or ordinary and necessary business expenses,
imposed or levied upon, assessed against or measured solely by the Fixed Minimum
Rent, Additional Rent or other charges to be paid by Tenant hereunder and
without regard to other income of Landlord; (c) all sales and use taxes which
may be levied or assessed against or be payable by Landlord or Tenant on account
of the leasing or use of all or any part of the Demised Premises; and (d) all
other taxes and charges in the same or similar categories. Tenant shall not be
required to pay any franchise, corporate, capital levy, estate, inheritance,
succession, transfer, federal, state, municipal or other income, profit or
revenue or similar taxes assessed or imposed against Landlord, the Demised
Premises, this Lease or any Fixed Minimum Rent or Additional Rent or other
charges due hereunder (other than any gross receipts, gross income or similar
taxes which fail to take into account deductions with respect to the Demised
Premises such as depreciation, interest, taxes or ordinary and necessary
business expenses, imposed or levied upon, assessed against or measured solely
by the Fixed Minimum Rent, Additional Rent or other charges to be paid by Tenant
hereunder, and without regard to other income of Landlord).

          16.3  To the extent that the same may be permitted by law, Tenant
shall have the right to apply for the conversion of any assessment for local
improvements assessed during the term of this Lease to be payable in annual
installments over the maximum time permitted by the municipal authority imposing
the same and upon such conversion Tenant shall be responsible for the payment of
only such installments thereof as shall be allocable to the term of this Lease.
Impositions, whether or not a lien upon the Demised Premises, shall be
apportioned between Landlord and Tenant at the beginning and end of the term of
this Lease; it being intended that Tenant shall pay only that portion of the
Impositions as is allocable to the term of this Lease; provided, however, that
Landlord need not make any apportionment in Tenant's favor if the term of this
Lease shall be terminated by reason of a default on the part of Tenant hereunder
unless and until such default is cured.

          16.4  Tenant, at its own expense, may contest any Impositions,
including a proceeding to reduce the assessed value of the Demised Premises
through tax certiori proceedings, in any manner permitted by law, in Tenant's
name, and whenever necessary in Landlord's name.  Landlord agrees that if
requested by Tenant, Landlord will remit Tenant's payments for Impositions to
the appropriate authority under protest.  Landlord will cooperate with Tenant
and execute any documents or pleadings reasonably required for such purpose;
provided, however, that the same shall be without cost, liability or expense to
Landlord.  Such contest may include appeals from any judgment, decree or order
until a final determination is made by a court or governmental department or
authority having final jurisdiction in the matter.  However, notwithstanding
such contest, Tenant shall promptly pay the contested Impositions in the manner
provided for in this Article, if at any time the Demised Premises or any part
thereof shall, as a result of the deferment of such payment, be subject to
forfeiture or if Landlord shall be subject to any criminal liability by reason
of the non-payment thereof.  Any tax refund with respect to any Imposition paid
by Tenant shall, to the extent thereof, be the property of Tenant.  Landlord, at
its expense, may contest any Imposition only in the event that Tenant is not
actively contesting any such Imposition, provided that Landlord provides Tenant
with written notice of its intention to contest such Imposition prior to the
commencement thereof.

          17.1  If Tenant shall fail to comply fully with any of its obligations
under this Lease (including without limitation, its obligations to make repairs,
maintain insurance, comply with all laws, ordinances and regulations and pay all
bills for utilities) after receipt of written notice of such failure from
Landlord and the expiration of any applicable grace periods, then Landlord shall
have the right, at its option, to cure such breach

                                       29
<PAGE>
 
at Tenant's expense.  Tenant agrees to reimburse Landlord for all costs and
expenses incurred as a result thereof together with the Default Charge which
Default Charge shall not begin to accrue until the date that Tenant receives a
written demand for such reimbursement from Landlord.

          17.2  Without limiting any rights granted to Tenant under Article 20.3
hereof, and notwithstanding any contrary provision of this Lease, if Landlord
shall fail to fully comply with any of its obligations under this Lease
(including without limitation, its obligations to make repairs or restoration in
connection with a casualty) and such failure shall continue for thirty (30) days
after receipt of written notice of such default from Tenant, Tenant shall
thereafter, upon notice to Landlord, have the right to cure such default at
Landlord's expense; provided, however, that if the said default shall be of a
nature that the same cannot be completely cured or remedied within said thirty
(30) day period and if Landlord shall commence the curing of such default
promptly, then the time of Landlord within which to cure the same shall be
extended for such period as may be necessary to complete the same with all due
diligence.  Landlord agrees to promptly reimburse Tenant for any costs and
expenses incurred as a result thereof, together with interest thereon at the
Default Charge.  If Landlord does not reimburse Tenant within ten (10) business
days of its receipt of a written request thereof from Tenant, Tenant shall be
entitled to offset and deduct such expenses from the next Fixed Minimum Rent
payment due hereunder.

          18.1  This Lease may be canceled by Landlord after the happening of
any one or more of the following events: (1) the commencement of a case in
bankruptcy or under the laws of any State naming Tenant as the debtor; or (2)
the making by Tenant of an assignment or any other arrangement for the benefit
of creditors under any State statute. Landlord, (a) at any time after receipt of
notice of the occurrence of any such event, or (b) if such event occurs without
the acquiescence of Tenant, at any time after the event continues for one
hundred twenty (120) days, may give Tenant a notice of intention to end the Term
of this Lease at the expiration of five (5) days from the date of service of
such notice of intention and, upon the expiration of said five (5) day period,
this Lease and the Term and estate hereby granted shall terminate with the same
effect as if that date were expressly set forth in this Lease, but Tenant shall
remain liable for damages as hereinafter provided. Neither Tenant nor any person
claiming through or under Tenant, or by reason of any statute or order of court,
shall thereafter be entitled to possession of the Demised Premises but shall
forthwith quit and surrender the Demised Premises.

     18.2  It is stipulated and agreed that in the event of the termination of
this Lease pursuant to Section 18.1, Landlord shall forthwith, notwithstanding
any other provisions of this Lease to the contrary, be entitled to recover from
Tenant as and for liquidated damages an amount equal to the excess of the rent
reserved hereunder for the unexpired portion of the Term demised over the then
fair and reasonable rental value of the Demised Premises for the same period. In
the computation of such damages the difference between any installment of rent
becoming due hereunder after the date of termination and the fair and reasonable
rental value of the Demised Premises for the period for which such installment
was payable shall be discounted to the date of termination at the annual rate of
interest payable with respect to the first mortgage encumbering the Demised
Premises. Nothing herein contained shall limit or prejudice the right of the
Landlord to prove for and obtain as liquidated damages (in lieu of other
damages) by reason of such termination, an amount equal to the maximum allowed
by any statute or rule of law in effect at the time when, and governing the
proceedings in which, such damages are to be proved, whether or not such amount
be greater, equal to or less than the amount of the difference referred to
above.

     19.1  If Tenant shall: (a) (i) default in the payment of the Fixed Minimum
Rent or any other item of Rental reserved herein payable on a regular monthly
basis for ten (10) days after Tenant's receipt of written notice of such
default, or (ii) in the payment of any other obligation involving the payment of
money within ten (10) business days after receipt of written notice from
Landlord; or (b) default in the observance of any of the other terms, covenants
and conditions of this Lease (except those expressly enumerated in this Section
19.1) and such default shall continue for more than thirty (30) business days
after written notice of such default, provided, however, that if the said
default shall be of a nature that the same cannot be completely cured or
remedied within said thirty (30) business day period and if Tenant shall
commence the curing of such default promptly, then the time of Tenant within
which to cure the same shall be extended for such period as may be necessary to
complete the same with all due diligence; or (c) if the Demised Premise shall be
occupied by someone other than Tenant in violation of the provisions of this
Lease and such occupancy shall continue for thirty (30) business days after
Tenant's receipt of written notice of such violation, or (d) if this Lease shall
be assigned or pass to or devolve upon one other than Tenant, except as herein
permitted; (e) if a receiver or trustee of Tenant and/or its property shall be
appointed in any proceedings other than bankruptcy proceedings and such
appointments, if made in proceedings instituted by or against Tenant, shall not
be vacated within one hundred twenty (120) business days after it has been

made; or (f) Tenant shall vacate the Demised Premises or any substantial portion
of the Demised Premises for any consecutive period in excess of eighteen (18)
months, it being agreed that Tenant shall not be in default under this Lease if
Tenant vacates the Demised Premises or any substantial portion of the Demised
Premises for a consecutive period of less than eighteen (18) months provided
that Tenant fulfills all of its obligations under this Lease (including, but not
limited to, the obligations contained in Article 7 hereof) during such period,
and provided further that Tenant provides Landlord with reasonable assurances
that Tenant will continue to fulfill its obligations hereunder, then upon the
happening of any one or more of the defaults or events above mentioned in this
Article and the continuance thereof beyond the applicable cure period, this
Lease and the Term hereof shall upon the date specified in a notice, which date
shall be not less than five (5) business days after the date of sending of such
notice by Landlord to Tenant, wholly cease and expire, with the same force and
effect as though the date so specified were the date hereinabove first set forth
as the date of the expiration of the Term (but Tenant shall remain liable to
Landlord as hereinafter provided); and thereupon, or at any time thereafter,
Landlord may recover possession thereof in the manner prescribed by the statute
relating to summary proceedings, or similar statutes (but Tenant shall remain
liable to Landlord as hereinafter provided), it being understood that no demand
for reentry for condition broken and no notice to quit possession or other
notices prescribed by statute shall be necessary to enable Landlord to recover
such possession but that all right to any such demand and any such re-entry and
any notice to quit possession or other statutory notices or prerequisites are
hereby expressly waived by Tenant to the extent such waiver is permitted by law.

     19.2  Notwithstanding any other provision in this Article, no termination,
re-entry, or dispossess by summary proceedings or otherwise, no termination by
operation of law or otherwise, and no reletting of the Demised Premises shall
relieve Tenant of its liabilities and obligations hereunder, all of which shall
survive such termination, re-entry, repossession or reletting.

     19.3  In case of any such termination, re-entry, or dispossess by summary
proceedings or otherwise, the Fixed Minimum Rent, Additional Rent and all other
charges required to be paid by Tenant hereunder shall thereupon become due and
be paid up to the time of such termination, re-entry or dispossess, and Tenant
shall also pay to Landlord all reasonable expenses which Landlord may then or
thereafter incur for attorneys' fees, brokerage commissions, and all other costs
paid or incurred by Landlord for recovering and restoring the Demised Premises
to good order and condition and for preparing the same for re-letting. Landlord
may, at any time and from time to time, re-let the Demised Premises, in whole or
in part, either in its own name or as agent

of Tenant, for a term or terms which at Landlord's option, may be for the
remainder of the Term of this Lease or for any longer or shorter period, and
(unless the statute or rule of law which governs or shall govern the proceeding
in which such damages are to be proved, limits or shall limit the amount of such
claim capable of being so proved and allowed, in which case Landlord shall be
entitled to prove as and for liquidated damages and have allowed an amount equal
to the maximum allowed by or under any such statute or rule of law) Tenant shall
be obligated to and shall pay to Landlord as damages, upon demand, and Landlord
shall be entitled to recover from Tenant damages (payable in monthly
installments, in advance, on the first day of each calendar month following such
termination, re-entry or dispossess, and continuing until the date originally
fixed herein for the expiration of the Term) in an amount or amounts equal to
the excess, if any, of the sum of the aggregate expenses paid by Landlord during
the month immediately preceding such calendar month for all such items as, by
the terms of this Lease, are required to be paid by Tenant, plus an amount equal
to the amount of the installment of Fixed Minimum Rent which would have been
payable by Tenant hereunder in respect of such calendar month, had this Lease
and the Term not been so terminated, or had Landlord not so re-entered, over the
rents, if any, collected by Landlord in respect of such calendar month pursuant
to such reletting (provided that if Landlord acted unreasonably in connection
with such reletting, given the market conditions then existing, Landlord shall
be deemed to have collected the fair market rental value of the Demised Premises
in respect of such calendar month), and any suit or action brought to collect
the amount of the deficiency for any month shall not prejudice in any way the
rights of Landlord to collect the deficiency for any subsequent month by a
similar proceeding. Provided that Landlord acts reasonably and in good faith,
(i) Landlord shall in no event be liable in any way whatever for failure to re-
let the Demised Premises and Landlord shall have no obligation or affirmative
duty to re-let or attempt to re-let the Demised Premises, nor to accept a new
tenant suggested by or supplied by Tenant and (ii) in the event that the Demised
Premises are re-let, Landlord shall not be liable for failure to collect the
rent thereof under such re-letting.

     19.4  Landlord, at Landlord's option, may make such alterations, repairs,
replacements and/or decorations in the Demised Premises as Landlord, in
Landlord's sole reasonable judgment, considers advisable and necessary for the
purpose of reletting the Demised Premises; and the making of such alterations
and/or decorations shall not operate or be construed to release Tenant from
liability hereunder.

     19.5  In the event of a breach or threatened breach by Tenant of any of the
covenants or provisions of this Lease, Landlord shall have the right to seek an
injunction and the right to invoke any remedy allowed at law or in equity as if
reentry,

                                       33

summary proceedings and other remedies were not herein provided for. Mention in
this Lease of any particular remedy shall not preclude Landlord from any other
remedy, in law or in equity.

     19.6  No receipt of Rental by Landlord from Tenant after the termination in
any way of this Lease or after giving any notice, shall reinstate, continue or
extend the Term, or affect any notice. No receipt of Rental after the
commencement of suit, or after final judgment for possession of the Demised
Premises, shall reinstate, continue or extend the Term or affect said suit or
said judgment.

                      SUBORDINATION, ATTORNMENT AND NON-DISTURBANCE
                      ---------------------------------------------

     20.1  This Lease, at the option of Landlord or any Mortgagee or
Overlandlord, shall be or shall become subject and subordinate, to all
Overleases, and to all Mortgages, and all advances thereon, which may now or
hereafter affect this Lease or the Demised Premises, and to all renewals,
modifications, consolidations, participations, replacements and extensions of
such Overleases and/or Mortgages; provided, however, any such Mortgagee or
Overlandlord must execute and deliver to Tenant an agreement substantially in
the form of Exhibit F attached hereto (a "Non-Disturbance Agreement") containing
provisions to the effect that, as long as Tenant is not in default under the
terms, covenants and conditions of this Lease beyond any grace period provided
in this Lease for remedying the same, in any action or proceeding to terminate
the Overlease, or to foreclose the Mortgage, Tenant will not be made a party
defendant, that Tenant's possession of the Demised Premises will not be
disturbed, and that Tenant's leasehold estate and its rights and remedies
hereunder will not be affected, impaired or terminated by any such action or
proceeding or by any judgment or order rendered therein. The term "Mortgages" as
used herein shall be deemed to include trust indentures and deeds of trust.

     In the event that Landlord, any Mortgagee or any Overlandlord elects to
subject and subordinate this Lease as mentioned in the preceding paragraph, then
Landlord or its Mortgagee or Overlandlord shall give Tenant notice to such
effect, and provided that such Mortgagee or Overlandlord shall have duly
executed and delivered to Tenant a Non-Disturbance Agreement, immediately
thereafter the aforesaid provisions shall be self-operative and no further
instrument of subordination shall be required. In the event Landlord or any
Overlandlord or any Mortgagee desires confirmation of such subordination, Tenant
shall execute promptly a confirmatory certificate in form reasonably acceptable
to Tenant upon Landlord's request.

     20.2  Tenant agrees that neither the cancellation nor the termination of
any Overlease, nor any foreclosure of any Mortgage, nor any proceeding to
recover possession of the Demised

                                       34
<PAGE>
 
Premises shall by operation of law or otherwise result in the cancellation or
termination of this Lease or the obligations of the Tenant hereunder. Tenant
covenants and agrees that upon delivery of a duly executed Non-Disturbance
Agreement, it shall attorn to any Mortgagee or Overlandlord or to the purchaser
of the Demised Premises in foreclosure or the sale of the Overlease, or any of
their respective successors or assigns or any other person claiming by or
through any such Mortgagee, or the Overlandlord, or by or through any
foreclosure proceeding of any such Mortgage, or any proceeding with respect to
such Overlease, who shall succeed to the rights of Landlord under this Lease;
and Tenant shall recognize such successor as Tenant's landlord under this Lease.
Upon such attornment this Lease shall continue in full force and effect as a
direct lease between Tenant and such successor landlord, upon and subject to all
of the terms, covenants and conditions of this Lease with the same force and
effect as if this Lease had originally been entered into by such successor
landlord and Tenant; except that such successor landlord and each succeeding
landlord shall not be: (a) liable for any act or omission of any prior landlord
(including Landlord); (b) subject to any offset, defense or counterclaim which
Tenant might have against any prior landlord (including Landlord); (c) bound by
any prepayments of more than one (1) month's Fixed Minimum Rent or additional
rent which Tenant may have paid to any prior landlord (including Landlord); or
(d) bound by any amendment or modification of this Lease made without its
consent. The provisions of this Article shall be self-operative, and no
instrument of attornment shall be required or needed. In confirmation of any
such attornment, Tenant shall promptly execute and deliver such instruments as
may be reasonably required.

     20.3  In the event of any act or omission by Landlord which would give
Tenant the right to terminate this Lease or claim a partial or total eviction,
or, except pursuant to Section 17.2, make any claim against Landlord for the
payment of money, Tenant will not exercise such right until it has given written
notice of such act or omission to

           (i)  the Landlord; and

           (ii) the Mortgagee and the Overlandlord as to whom Landlord has
instructed Tenant to give copies of all of Tenant's notices to Landlord,

and unless Landlord shall not have remedied such act or omission within thirty
(30) days from its receipt of such written notice, or, if such act or omission
cannot be remedied by the payment of money and is not capable of being remedied
within said thirty (30) day period, Landlord shall not have commenced the remedy
of such act or omission within said thirty day period or shall not diligently
pursue the completion of such remedy. Nothing herein contained shall be deemed
to create any rights in Tenant not

                                       35
<PAGE>
 
specifically granted in this Lease or under any applicable provision of law.

                         SURRENDER OF DEMISED PREMISES
                         -----------------------------

     21.1  On the last day or sooner termination of the Term, Tenant shall quit
and surrender the Demised Premises broom clean, in good condition and repair
(reasonable wear and tear, casualty and condemnation excepted), as provided in
Sections 11.4, 11.5 and 11.6 of this Lease. If the Demised Premises be not
surrendered as and when aforesaid and such failure to surrender shall continue
for three (3) months thereafter, Tenant shall indemnify Landlord against loss or
liability directly resulting from the delay by Tenant in so surrendering the
Demised Premises, including, without limitation, any claims made by any
succeeding occupant or prospective occupant of the Demised Premises founded upon
such delay. Upon expiration of the then current term of this Lease, without
premature termination, for the number of days that Tenant remains in possession
of the Demised Premises, without the execution of a new lease, Tenant shall be
deemed to be occupying said Demised Premises at a Rental equal to 125% of the
amount of the Rental (Fixed Minimum Rent), and 100% of the additional charges
herein provided for each month or part thereof and otherwise be subject to all
the conditions, provisions, and obligations of this Lease insofar as the same
are applicable to a month-to-month tenancy.

     Tenant's obligations under this Article 21 shall survive the expiration or
sooner termination of the Term.

hereafter but not more often than four (4) times each year, within twenty (20)
days after written request of Landlord, certify by a written instrument duly
executed and acknowledged to any mortgagee or purchaser, or proposed mortgagee

if so the substance and manner of such supplement or amendment; (b) as to the
validity and force and effect of this Lease, in accordance with its tenor as
then constituted; (c) as to the existence of any default by Landlord hereunder
known to Tenant; (d) as to the existence of any offsets, counterclaims or
defenses thereto on the part of Tenant known to Tenant; (e) as to commencement
and expiration dates of the Term; and (f) as to any other matters as may
reasonably be so requested. Any such certificate may be relied upon by Landlord
and any other person, firm or corporation to whom the same may be exhibited or
delivered; and the contents of such certificate shall be binding on Tenant.

     22.3  In addition to the provisions of Section 22.1 of this Lease, Tenant
agrees to furnish directly to Landlord's proposed lender upon Landlord's
request, within six (6) months from the end of each of Tenant's fiscal years,
Tenant's consolidated financial statements prepared by independent certified
public accountants. Landlord agrees to keep such financial information
confidential; and to deliver such statements only to the party proposing to give
such financing and/or proposing to purchase the Demised Premises or the Park and
only if such party agrees, in a manner reasonably acceptable to Tenant, to
preserve such confidentiality.

     23.1  It is mutually agreed by and between Landlord and Tenant that the
respective parties hereto shall and they hereby do waive trial by jury in any
action, proceeding or counterclaim brought by either of the parties hereto
against the other on any matters whatsoever arising out of or in any way
connection with this Lease, the relationship of Landlord and Tenant, Tenant's

     24.1  Landlord covenants and agrees with Tenant that upon Tenant paying the
Rental and observing and performing all the terms, covenants and conditions on
Tenant's part to be observed and performed, Tenant may peaceably and quietly
enjoy the Demised Premises without hindrance or ejection by Landlord or

                                       37

     25.1  Tenant covenants, warrants and represents that Tenant has not dealt
with any broker in connection with this Lease, other than Landlord's broker,
Spectra Realty, and any other person or entity identified by Tenant in writing
to Landlord. Tenant agrees to hold Landlord harmless against any liability or
expense arising out of a misrepresentation by Tenant in the preceding sentence.
Landlord agrees to be responsible for any brokerage commissions which may be
payable to Spectra Realty, and hereby agrees to indemnify Tenant from any claims
of Spectra Realty or any other person or entity claiming a commission in
connection with this Lease, including all costs and expenses in connection
therewith.

                                 -------------

     26.1  The obligations of this Lease shall bind and benefit the successors
and assigns of the parties with the same effect as if mentioned in each instance
where a party is named or referred to, except that no violation of the
provisions of Article 14 shall operate to vest any rights in any successor or
assignee of Tenant and that the provisions of this Article shall not be
construed as modifying the provisions of Article 14. All covenants and
agreements of this Lease shall run with the Land. The term "Landlord" as used in
this Lease means only the owner or the mortgagee in possession for the time
being of the Demised Premises so that in the event of any sale of said Demised
Premises or an assignment of this Lease Landlord shall be and hereby is entirely
freed and relieved of all obligations of Landlord hereunder and it shall be
deemed without further agreement between the parties and such purchaser(s) or
assignee(s) that the purchaser or assignee has assumed and agreed to observe and
perform all obligations of Landlord hereunder, subject to the exculpation
provisions of the immediately following paragraph.

     Notwithstanding anything to the contrary provided in this Lease, it is
understood and agreed that, except in the case of fraud or intentional
misconduct by Landlord in connection with this Lease or the misapplication of
any funds, insurance proceeds or condemnation awards received by Landlord under
or in connection with this Lease, there shall be no personal liability on the
part of Landlord or any officer, director, shareholder or agent of Landlord (or
any successor corporate landlord or any partner of any limited or general
partnership which may become Landlord or any individual or other entity) to
Tenant with respect to any of the terms, covenants and conditions of this

Lease except to the extent of the Demised Premises and the proceeds thereof, and
Tenant agrees that it shall look solely to the Demised Premises and the proceeds
thereof for the satisfaction of any claims, debts, demands or judgments of
Tenant in the event of breach or default by Landlord under the terms of this
Lease, except in the case of fraud or intentional misconduct by Landlord in
connection with this Lease or the misapplication of any funds, insurance
proceeds or condemnation awards received by Landlord under or in connection with
this Lease. No other property or assets of Landlord shall be subject to
judgment, levy, execution or other enforcement procedure for the satisfaction of
Tenant's remedies under or with respect to this Lease, the relationship of
Landlord and Tenant hereunder or Tenant's use or occupancy of the Demised
Premises. The foregoing shall not limit or restrict Tenant's right to obtain as
against Landlord affirmative or negative injunctive relief or any other relief
similar to such injunctive relief.

the event the addressee or such agent of the addressee shall refuse to receive
any notice given by registered mail or certified mail as above provided the time
of the giving of such notice shall be the time of such refusal. If the sender of

addressee of a change of address of said addressee, such changed address shall
thereafter as to such sender be deemed the address to which future notices shall

Landlord or any designee of Landlord in, to, or through all areas of the Demised
Premises, except the Building,

                                       39

for the installation, repair, maintenance and replacement of pipes, cables,
conduits and wires at reasonable times and upon reasonable written notice to
Tenant to the extent that Landlord may now or hereafter deem to be necessary or
appropriate for the proper operation and maintenance of the Demised Premises or
any other portion of the Park or which may be required by Laws and Ordinances,
provided that Tenant shall have the right to approve the location of such pipes,
cables, conduits and wires and provided further that Landlord's installation,
repair, maintenance or replacement thereof does not substantially interfere with
any of the parking spaces located on the Demised Premises. Landlord agrees to
cause the least interference with Tenant's use of the Demised Premises. All such
work shall be done in such manner as to cause the least interference with
Tenant's use of the Demised Premises, and Landlord shall repair and replace all
areas of the Demised Premises damaged by such installation, repair, maintenance
and replacement to the same condition as existed immediately prior to the
commencement of such work.

     29.1  Landlord and owners of other property intend to develop, or cause to
be developed, a first class corporate/industrial park; but nothing herein
contained shall be deemed a representation by Landlord (or a requirement that
Landlord) construct any portion of the Park or the size of the Park nor shall
Landlord be limited from time to time in changing the size thereof. Tenant
agrees to keep the Land clean of unsightly objects or debris. Tenant shall
maintain the landscaping on the Demised Premises as set forth in the final
approved subdivision plan and as initially installed by Landlord. All
landscaping areas shall be maintained in good order and condition, including
watering when necessary for continued growth and cutting; and no weeds or
underbrush nor unsightly growth of any kind shall be permitted. There shall be
no outside storage, except for adequately screened garbage dumpsters, provided
same are permitted by Laws and Ordinances.

     30.1  One or more waivers of any covenant or condition by Landlord shall
not be construed as a waiver of a subsequent breach of the same or any other
covenant or condition, and the consent or approval by Landlord to or of any act
by Tenant requiring Landlord's consent or approval shall not be construed to
waive or render unnecessary Landlord's consent or approval to or of any
subsequent similar act by Tenant. Landlord's failure to prepare any of the bills
for Impositions or any other bills or statements shall not in any way cause
Landlord to forfeit or surrender its rights to collect any of such items of
additional

                                       40

rent that may have become due during the Term; which right shall survive the
termination of this Lease.

     30.2  This Lease (together with the Development Agreement) contains the
entire agreement of the parties with respect to the subject hereof, and no oral
statement or prior written matter (other than the terms of the Development
Agreement) shall have any force of effect. No waiver of any provision of this
instrument shall be effective unless in writing, signed by the waiving party.
Tenant agrees that it is not relying on any representations or agreements other
than those contained in this Lease and the Development Agreement. This Lease
shall not be modified except by a writing subscribed by Landlord and Tenant, nor
canceled by Tenant except with the written consent of Landlord, unless otherwise
specifically provided herein.

     30.3  If any provision of this Lease shall be invalid or unenforceable in
whole or in part, the remainder of this Lease shall not be affected thereby and
each and every provision of this Lease shall be enforceable to the fullest
extent permitted by Laws and Ordinances. This Lease shall be interpreted in
accordance with and be governed by the Laws and Ordinances of the State of New
York.

     30.4  Tenant waives any and all rights of redemption conferred by statute
or otherwise, to the maximum extent permitted by Laws and Ordinances, upon the
expiration or sooner termination of the Term, or upon the entry of final
unappealable judgment for recovery of possession through any action or
proceeding.

the plural, and the masculine gender shall include the feminine and neuter
genders. The paragraph headings used herein are for reference and convenience
only, and shall not enter into the interpretation of this Lease. The words
"reenter" and "reentry" as used herein are not restricted to their technical
legal meaning.

     30.6  Nothing in this Lease shall cause Landlord in any way to be construed
as a partner, joint venturer, or an associate of Tenant in the operation of the
Demised Premises.

to a warehouse and office facility located in the Mt. Ebo Office Park in the 
Town of Southeast, County of Putnam, State of New York (the "Demised Premises");
and

          WHEREAS, Landlord is about to execute a first Mortgage to Mortgagee
dated of even date herewith (the "Mortgage") securing a loan in the amount of
                                       ($              ), and Mortgagee has
- --------------------------------------   -------------
refused to make said loan unless it is secured by a mortgage prior in right and
interest to the Lease and the interests of Tenant under the Lease; and


          WHEREAS, Tenant has agreed that the Lease shall be subject and
subordinate to mortgages affecting the Demised
<PAGE>
 
Premises provided that the mortgagee thereunder delivers to Tenant an agreement
in the form of this Agreement.

          NOW, THEREFORE, in consideration of the Premises and ONE DOLLAR
($1.00) paid to Tenant, the receipt and sufficiency of which are hereby
acknowledged and intending to be legally bound, Tenant and Mortgagee covenant
and agree as follows:

          1.  Mortgagee agrees that, for as long as Tenant is not in default
beyond any applicable notice and/or grace period under any of the terms,
covenants or conditions of the Lease, if any action or proceeding is commenced
by Mortgagee for the foreclosure of the Mortgage, Tenant shall not be named as a
party therein, and the right of possession of Tenant to the Demised Premises
shall not be affected or disturbed, and upon the sale of the Demised Premises in
any such action or proceeding, the Mortgagee or other purchaser of the premises
shall accept the attornment of Tenant and recognize the rights of Tenant under
the Lease.

          2.  In the event that Mortgagee or such other purchaser shall succeed
to the interests of Landlord under the Lease as aforesaid, Tenant agrees to
attorn to and accept Mortgagee or such other purchaser as its landlord under the
Lease for the balance of the term thereof and Mortgagee or such other purchaser
shall be bound to Tenant under all the terms, covenants and conditions of the
Lease and Tenant shall, from and after such event, have the same remedies
against Mortgagee or such other

                                       2
<PAGE>
 
purchaser for the breach of an agreement contained in the Lease that Tenant
might have had under the Lease against Landlord if Mortgagee or such other
purchaser had not succeeded to the interest of Landlord; provided, however, that
Mortgagee or such other purchaser shall not be:

              (i)   bound by any payment of rent or additional rent made by
Tenant for more than one month in advance;

              (ii)  bound by any amendment or modification of the Lease, dated
subsequent to this Agreement, made without the consent of Mortgagee;

              (iii) liable for any previous act or omission of any prior
landlord, including Landlord, under the Lease; or

              (iv)  subject to any offset or counterclaim or defense which shall
theretofore have accrued to Tenant against any prior landlord, including
Landlord, under the Lease.

          3.  Tenant agrees to give prompt written notice to Mortgagee of any
default of Landlord in the obligations of Landlord under the Lease, if such
default is of such nature as to give Tenant a right to terminate the Lease,
reduce rent or to credit or offset any amounts against future rents.  It is
further agreed that such notice will be given to any successor in interest of
Mortgagee in said Mortgage provided that prior to any such default of Landlord
such successor in interest shall have given written notice to Tenant of its
acquisition of Mortgagee's

                                       3
<PAGE>
 
interest therein, and designated the address to which such notice is to be
directed.  Tenant further agrees that notwithstanding any provision of the Lease
to the contrary, no notice of cancellation thereof shall be effective unless
Mortgagee, or such successor in interest, has received such notice of default
within thirty (30) days of the date thereof (or if the default cannot be cured
within thirty (30) days in the exercise of reasonable diligence, has had the
opportunity to commence the cure thereof within said thirty (30) day period) and
thereafter completes the cure with reasonable diligence.

     4.   TERM AND OPTION.

          4.1  The TERM of the INITIAL LEASE PERIOD shall be for One Hundred
Twenty (120) months, commencing on the thirtieth day after the Lessee has use of
the Premises, the "Lease Commencement Date".

          4.2  If the Lease Commencement Date occurs on other than on the first
day of the month, the Lessee will pay a pro rata rental for the portion of the
month that the Premises are occupied by Lessee, based upon a full month's

                                     - 2 -
<PAGE>
 
rental for a month containing 30 days.

          4.3  It is anticipated that Lease Commencement date shall be
approximately August 15, 1990. The Occupancy Date (approximately July 15, 1990)
shall be established when a Certificate of Occupancy (temporary or final) is
issued; or upon initial occupancy of premises by Tenant for Tenant
fixturization, whichever occurs first. The representatives of Lessor and Lessee
shall mutually agree to a date that occupancy will commence (or had commenced)
and a letter executed by representatives of both Lessor and Lessee shall be
appended to the Lease.

          4.4  In the event Lessor has not completed the premises for Tenant
fixturization by August 30, 1990, then Lessee shall have the right to (i)
complete the Tenant Improvements pursuant to the plans and specifications
therefor, in which event all costs incurred by Lessee in connection with such
work shall be paid to Lessee by Lessor immediately upon demand therefor, (ii)
terminate this Lease, which termination shall be effective thirty (30) days
after notice of termination is delivered to Lessor by Lessee. Notwithstanding
the foregoing, if the Lessor has diligently expended efforts to deliver
possession of the premises, but was precluded by delays outside of his control,
the above dates shall be reasonably extended.

          4.5  Lessor does hereby grant to Lessee the Option to Extend the Term
of this Lease for three (3) additional 60 month periods, commencing upon the
expiration of the Initial 120 month Term, upon the following terms and
conditions:
 
               (a)  Lessee shall give Lessor written notice at least 240 days
prior to the expiration of the Initial Term, or any extended Term of this Lease,
as applicable. Failure to give such written notice shall extinguish and make
null and void the Option to Extend.

               (b)  The Option(s) are expressly conditioned upon Lessee's not
being in default at the time notice of election to exercise the option(s) is
given. Such default refers to any requirement under this entire Lease, which
remains uncured by Lessee at the time notice is given, and for which the time in
which to cure such default has expired on the date notice is given.

               (c)  During the First, Second, and Third Extended Option Term(s),
all the terms and conditions of this Lease shall control the occupancy of the
Premises by Lessee.

               (d)  Notwithstanding the above, it is understood by Lessor and
Lessee that the 121st through 300th month period is an Option Period and said
rents shall be required only if Option is exercised by Lessee, as required and
set forth herein.

          4.6  During the Initial Term of this Lease, and during any Extended
Term, Lessor shall not enter into any Lease affecting any additional space
within the PHASE II (contemplated as PH.IIA & IIB) building which is contiguous
to the Premises, which may from time to time be vacant, without first offering
Lessee an opportunity to lease such space on the terms and conditions Lessor is
willing to lease such space to a third party, except that the Monthly Rental
shall be as set forth below; and the Tenant improvements to be

                                     - 3 -
<PAGE>
 
installed by Lessor shall include only: demising walls, lighting, evaporative
cooling and ventilating facilities (the "Standard Warehouse Improvements").
Lessor shall offer such opportunity to lease to Lessee by notifying Lessee in
writing of the proposed terms and conditions thereof, or at Lessor's option, by
submitting to Lessee a copy of such offer to lease. If, within ten (10) business
days of the date of receipt of such notice, Lessor has received written notice
from Lessee of its election to lease such space on the same terms and conditions
of such proposed lease, except for Monthly Rental and the Standard Warehouse
Improvements, then Lessor shall not enter into a lease with the Third Party and
Lessor and Lessee shall promptly enter into a separate lease, or addendum
hereto, on the same terms and conditions as set forth in proposed Lease. The
term of such lease or addendum shall correspond with the Term of the Third Party
Proposal, and the Monthly Rental shall be as set forth below. If Lessor has not
received Lessee's written election to lease such space within the 10 business
day period, Lessor shall be free to execute a proposed lease with the Third
Party.

     Note:  Lease Month 0l (Initial term), corresponds to Initial Lease
Commencement Date.

     4.7  Notwithstanding Lessee's right of first refusal as set forth in
Section 4.6 above, Lessee shall have the right at any time during the Initial
Term of this Lease, or any Extended Term, to lease from Lessor any available
contiguous space in the Phase II building, at the rental rate set forth in Par.
4.6; provided, however, that unless otherwise agreed by Lessor and Lessee, (i)
the improvements to be installed by Lessor in such additional space shall
include only the Standard Warehouse Improvements, and (ii) if Lessee notifies
Lessor in the last twenty-four months of the Initial Term, or any Extended Term,
as applicable, that it desires to lease any such additional space, Lessee must
also elect to extend the term of this Lease for at least one Extended Term, as
provided in Section 4.5. For all such additional space, the Monthly Rental shall
be as set forth in Par. 4.6, unless the type and development of the space
differs from same, the proposal, or supplemental proposals, will provide the
basis to establish the Rent.

     4.8  In the event that a Lessee's requirements for additional/expansion
space cannot be provided by the Lessor in the subject facility, or the adjacent
facility, within a time frame of nine (9) months, the Lessor shall be obligated
to accomodate Lessee in any other available existing facility, or facilities,
owned by the Lessor. The Lessor may elect to develop and build a new facility to
accomodate the additional growth expansion, or a facility for a total
consolidated facility, at Lessor's option. If the Lessee and Lessor enter into a
Lease for a consolidated facility, this Lease shall terminate upon the
Commencement of the Lease in the new facility.

          Notwithstanding the foregoing, the Lessor shall not be obliged to

                                     - 4 -
<PAGE>
 
provide a consolidated expansion facility, if the Lessee has within a fifteen
(15) month period prior to the request, rejected additional space (of near
equivalent area to the requirement contemplated herein), as set forth in Par.
4.6.

          The Rate for any expansion area space shall be as set forth in Par.
4.6. The Rate for a consolidated facility shall be as established within this
Lease for the primary space, and as established in Par. 4.6 expansion space
portion.

     4.9  The Lessor shall not for a period of four (4) months after the date
of this lease, proceed with development and/or construction of the Phase IIB
building improvements, which constitutes the space set forth in Par. 4.6 and
4.7, without notice to Lessee.

     5.   SECURITY DEPOSIT. In lieu of security deposit, first month's rent
payment shall be made at signing of this Lease Agreement.

     6.   USE OF PREMISES.

          6.1  USE. The Premises shall be used and occupied for warehousing
and distribution of pharmaceutical compounds (including controlled substances),
materials required for manufacture of pharmaceuticals, and medical related
products, and any lawful purpose which does not violate any applicable zoning
ordinance, restrictive covenant, or other restriction upon the use of the
Premises.

          6.2  COMPLIANCE WITH LAW.

               (a)  Lessor warrants to Lessee that the Premises, in its state
existing on the date that the Lease occupancy commences, does not violate any
covenant or restrictions of record or any applicable building code, regulation
or ordinance in effect on such Occupancy Date. If it is determined that this
warranty has been violated, then it shall be the obligation of the Lessor, after
written notice from Lessee, to promptly and with due diligence, at Lessor's sole
cost and expense, rectify any such violation.

               If, during the terms of the Lease, it is determined that there
has been a violation of the warranty of Lessor, Lessee, upon learning of such
breach of warranty, shall give notice of such breach of warranty to Lessor
within 10 days after learning of same, by written notice of such breach, and
thereafter Lessor, at Lessor's sole cost and expense, shall cure such breach. If
such breach cannot be cured by Lessor after notice, and by reason thereof Lessee
is unable to continue its ordinary business upon the Premises, Lessee may
thereupon terminate this lease and be entitled to recover any rent paid and
unearned as of the date of such termination, or Lessee may elect to cure
Lessor's breach, in which event all costs incurred by Lessee in effecting such
cure shall be paid by Lessor to Lessee immediately upon Lessor's receipt of
demand therefor;

               (b)  Except as provided in paragraph 6.2 (a), Lessee shall, at
Lessee's expense, comply promptly with all applicable statutes, ordinances,
rules, regulations, orders, covenants, and restrictions of record if any, and
requirements in effect during the term, or any part of the term hereof,

                                     - 5 -

regulating the use by Lessee of the Premises. Lessee shall not use, nor permit
the use of, the Premises in any manner that will tend to create trash or waste
at the exterior portions of the Premises, or a nuisance, or if there shall be
more than one tenant in the building containing the Premises, the use by Lessee
shall not unreasonably disturb the use of other portions of the building by
other tenants.

               (c)  If a statute, ordinance, rule or regulation or order is
promulgated by a governmental subdivision having jurisdiction over the Premises
which renders it impractical for Lessee to continue the occupancy of the
Premises, then thereupon Lessee shall have the right to terminate this Lease
upon 90 days written notice of its election to so terminate. Such notice shall
cite to Lessor the statute, ordinance, rule, regulation, or order that makes
occupancy impractical, and shall further state the reason for the impracticality
of continued occupancy. Lessor represents and warrants that there are no
covenants and restrictions of record, as of the date of this Lease, that will
require Lessee to incur an expense other than as is herein specifically provided
for in this Lease Agreement.

     6.3  CONDITION OF PREMISES.

               (a)  Lessor shall deliver the Premises to Lessee clean and free
of debris and in a safe condition on the Lease Commencement Date, and Lessor
further warrants to Lessee that the plumbing, lighting, mechanical systems, and
loading doors, in and on the Premises, shall be in new, or operating condition
on the Lease Occupancy Date. If it is determined that the warranty has been
violated, then it shall be the obligation of Lessor, after receipt of written
notice from Lessee, setting forth with specificity the nature of the violation,
to promptly, at Lessor's sole cost, rectify such violation. Lessee's failure to
give such written notice to Lessor within 60 days after the Lease Commencement
Date, or within thirty (30) days after occupancy by Tenant of an expansion
phase(s), shall create the conclusive presumption that Lessor has complied with
all of Lessor's obligations under this Subparagraph 6.3(a). By reason of the
Premises being a newly constructed building, or as applicable to expansion
phase(s), Lessee shall have the benefit of any continuing warranties with
respect to equipment, and a one year warranty with respect to all new
construction. The Lessor shall provide Lessee, within 30 days of commencement
date, a list of subcontractors, suppliers, and related warranties thereto in
effect.

               (b)  Except as otherwise provided in this Lease, and subject to
Lessor's Warranties set forth in 6.2(a), 6.3(a), and 7.1, Lessee accepts the
Premises in their condition existing as of the Lease Commencement Date, or the
date that Lessee takes possession of the Premises, whichever is earlier, subject
to all applicable zoning, municipal, county and State Laws, ordinances and
regulations governing and regulating the use of the Premises and any covenants
or restrictions of record, and accepts this Lease subject thereto and to all
matters disclosed thereby and by any exhibits attached hereto, provided,
however, that Lessor does hereby expressly warrant that there will be no
violations of any such matters on such Lease Commencement Date. If, subsequent
to occupancy, Lessee discovers that a violation of any such matter has occurred,
and that such violation was in existence at the date of the commencement of the
occupancy of the Premises, then such violation shall be cured at the sole cost
and expense of Lessor. Written notice of any such

                                     - 6 -
<PAGE>
 
violation shall be given by Lessee to Lessor within 10 days after obtaining
knowledge of such violation.

     7.   MAINTENANCE, REPAIRS AND ALTERATIONS.

          7.1  LESSEE'S OBLIGATION. Lessee shall keep in good order, condition
and repair, the nonstructural portion of the Premises, and the mechanical
systems utilized for the Premises occupied by Lessee. Any structural repairs,
including, but not limited to, the roof framing (beams and plywood sheeting),
foundation, exterior walls, the floor structural section, as pertains to
settling (not including surface), and portions of the Premises not accessible to
Lessee, shall be maintained at the sole cost and expense of Lessor throughout
the term, and any extended term of the Lease, provided, however, that if there
is damage to the Premises by any act of omission or commission on the part of
the Lessee which causes a structural defect that requires repairs, then in that
event the cost of such repairs shall be paid by Lessee. Lessee shall maintain
plumbing, mechanical, and ventilating systems, electrical, and lighting
facilities, and any other equipment located within the Premises occupied by
Lessee, at Lessee's sole cost and expense. Lessee shall maintain the non-
warehouse area ceilings, floors (except structural defect), windows, doors,
plate glass and skylights located within the leased Premises. Notwithstanding
the foregoing, Lessor shall fully warrant the total Premises, including all
Tenant Improvements installed by Lessor, for a period of twelve (12) months from
the Lease Commencement Date, and for any items covered for extended periods by
manufacturers warranties for the time period of such extended warranties.

          Landscaping, driveways, parking lots and fences located adjacent to
the Premises, and the roofing of the building, in which the Premises are
located, shall be maintained by Lessor, the reasonable cost of such maintenance
to be paid by Lessee, on pro rata basis of space leased by Lessee, as compared
to total leasable space in the building, except for maintenance costs
attributable to Lessee's exclusive parking area which shall be the sole
responsibility of Lessee, subject to allocation as may be applicable.

          7.2  REPAIR OR SURRENDER. On the last day of the term hereof, or on
any sooner termination, Lessee shall surrender the Premises to Lessor in the
same condition as when received, ordinary wear and tear and construction defects
excepted, and the Premises shall be clean and free of debris. Lessee shall
repair any damage to the Premises occasioned by the installation or removal of
Lessee's trade fixtures, furnishings and equipment.

          7.3  LESSOR'S RIGHTS. If Lessee fails to perform Lessee's obligations
under this Paragraph 7, or under any other paragraph of this Lease, Lessor may
at its option (but shall not be required to) enter upon the Premises after ten
(10) days prior written notice to Lessee (except in the case of an emergency, in
which case no notice shall be required), perform such obligations on Lessee's
behalf and put the same in good order, condition and repair, and the cost
thereof shall become due and payable as additional rental to Lessor together
with Lessee's next rental installment.

          7.4  LESSOR'S OBLIGATIONS. Except for the obligations of Lessor under
Paragraph 6.2 (a) and 6.3 (a) (relating to Lessor's warranty), Paragraph 9
(relating to destruction of the Premises) Paragraph 14 relating to

                                     - 7 -
<PAGE>
 
condemnation of the Premises), and Paragraph 7.1 (relating to structural
repairs), it is intended by the parties hereto that Lessor have no obligation in
any manner whatsoever, to repair and maintain the Premises, nor the building
located thereon, nor the equipment therein, whether structural or nonstructural,
except as expressly provided in this Lease, and particularly as set forth in
Paragraph 7.1 above.

          If Lessor, for any reason, fails to perform its obligations under this
Paragraph 7, as it relates to other provisions of this Lease in respect to
Lessor's obligations regarding repairs of the Premises, (i) after 10 days
written notice, or in an emergency, immediately then in that event, Lessee may
make such repairs and deduct the cost thereof from the next monthly rental due
under the terms of this Lease, or due under the terms of the extended term of
this Lease, or (ii) after 30 days written notice Lessee may terminate this Lease
immediately upon written notice to Lessor.

          7.5  ALTERATIONS AND ADDITIONS.

               (a)  Lessee shall not, without Lessor's prior written consent,
which shall not be unreasonably withheld, make any alterations, improvements,
additions or Utility Installations in, on, or about the Premises, except for
nonstructural alterations not exceeding $5,000 in cumulative costs during any
six month period, during the term of this Lease. In any event, whether or not in
excess of $5,000 in cumulative costs, Lessee shall make no change or alteration
to the exterior of the Premises, nor the exterior of the building on the
Premises, without Lessor's written consent. As used in Paragraph 7.5, the term
"Utility Installations" shall mean airlines, power panels, electrical
distribution systems, mechanical systems, plumbing, and fencing. Lessor may
require that Lessee remove any or all of said alterations, improvements,
additions or Utility Installations at the expiration of the term and restore the
Premises to their prior condition.

               (b)  Any alterations, improvements, additions or Utility
Installations in, or about the premises that Lessee shall desire to make, which
require the consent of the Lessor, shall be presented to Lessor in written form,
with proposed preliminary or detailed plans. Lessor shall either approve, or
disapprove with reasonable cause, Lessee's request within ten (10) business days
after receipt of Lessee's request. If Lessor has not responded within said 
10-day period, Lessor shall be deemed to have approved Lessee's request. If
Lessor shall give its consent, the consent shall be deemed conditioned upon
Lessee acquiring a permit to do so from appropriate governmental agencies, the
furnishing of a copy thereof to Lessor prior to the commencement of the work and
the compliance by Lessee of all conditions of said permit in a prompt and
expeditious manner.

               (c)  Lessee shall pay, when due, all claims for labor or
materials furnished, or alleged to have been furnished to or for Lessee at or
for use in the Premises, which claims are or may be secured by any mechanics' or
materialmen's lien against the Premises or any interest therein. Lessee shall
give Lessor not less than ten (10) days notice prior to the commencement of any
work on the Premises, and Lessor shall have the right to post notices of
nonresponsibility in or on the Premises as provided by law. If Lessee shall, in
good faith, contest the validity of any such lien, claim or demand, then Lessee
shall, at its sole expense, defend itself and Lessor against the same

                                     - 8 -
<PAGE>
 
and shall pay and satisfy any such adverse judgement that may be rendered
thereon before the enforcement thereof against the Lessor or the Premises, upon
the condition that if Lessor shall require, Lessee shall furnish to lessor a
surety bond satisfactory to Lessor in an amount equal to such contested lien
claim or demand, indemnifying Lessor against liability for the same and holding
the Premises free from the effect of such lien or claim. In addition, Lessor may
require Lessee to pay Lessor's attorneys' fees and costs in participating in
such action if Lessor shall decide it is to its best interest to do so.

               (d)  Unless Lessor requires their removal, as set forth in
Paragraph 7.5 (a), all alterations, improvements, additions and Utility
Installations which may be made on the Premises, shall become the property of
Lessor and remain upon and be surrendered with the Premises at the expiration of
the term. Notwithstanding the provisions of this Paragraph 7.5 (d), Lessee's
machinery, trade fixtures, and equipment, other than that which is affixed to
the Premises so that it cannot be removed without material damage to the
Premises, which damage is incapable of being repaired within ten (10) days after
removal of Lessee's equipment, shall remain the property of Lessee and may be
removed by Lessee, subject to the provisions of Paragraph 7.2.

     8.   INSURANCE AND INDEMNITY.

          8.1  INSURING PARTY.  As used in this Paragraph 8, the term "insuring
party" shall mean the party to this Lease who has the obligation to obtain the
particular insurance described in each of the subsections of this Paragraph 8,
with respect to Property Damage to the Premises, Public Liability, and property
damage to property of another, by reason of conduct involving the Premises,
which are the subject of this Lease.

          All insurance, as hereafter provided, and any that is required to be
procured by Lessor, shall be at the cost and expense of Lessee, on a pro rata
basis as hereafter provided. The Lessor shall maintain a comprehensive general
liability policy to insure against loss by reason of the ownership of the
property, involving personal injury or property damage to another, however, the
Lessee shall be responsible only for a policy up to a maximum coveage of one
million dollars ($1,000,000) per occurrence. If the Lessor determines to procure
insurance for liability in excess of one million dollars per occurrence, the
cost of such additional coverage shall be paid solely by Lessor.  Any such
liability insurance procured by Lessor shall not reflect the Lessee as an
additional insured under such policy.

          All insurance that is procured by Lessor, except as to liability
insurance in excess of $1,000,000, shall be at the expense of Lessee and any
other tenants of the building within which the Premises are located, and the
land upon which such building is located. The cost shall be prorated among all
Lessees of any portion of the Real Property, or the building, and the proration
shall be on the basis of the square footage of space occupied by Lessee, as that
bears to the total number of square feet of building occupied by all tenants, or
available for occupancy of tenants, of the real property and building.

          8.2  LIABILITY INSURANCE.

                                     - 9 -
<PAGE>
 
          Lessee shall, at Lessee's expense, obtain, pay for directly, and keep
in force during the term of this Lease, a policy of Combined Single Limit,
Bodily Injury and Property Damage Insurance, insuring Lessor and Lessee against
any liability arising out of the ownership, use occupancy or maintenance of the
Premises and all areas appurtenant thereto. Such insurance shall be a combined
single limit policy in an amount not less than $1,000,000 per occurrence. Lessee
shall have the right to provide such insurance coverage, pursuant to blanket
policies obtained by Lessee.

          The policy shall insure performance by Lessee of the indemnity pro-
visions of Paragraph 8. The limits of said insurance shall not, however, limit
the liability of Lessee hereunder.

          8.3  PROPERTY INSURANCE.

          (a)  The Lessor shall procure and obtain, and keep in force during the
term of this Lease, at Lessee's expense, a policy or policies of insurance
covering loss or damage to the Premises, in the amount of the full replacement
value thereof, as the same may exist from time to time. The replacement value is
$2,100,000, but in no event less than the total amount required by lenders
having liens on the Premises, against all perils included within the
classification of fire, extended coverage, vandalism, malicious mischief, flood,
(in the event same is required by a lender having a lien on the Premises), and
special extended perils ("All Risk" as such term is used in the insurance
industry). Said insurance shall provide for payment of loss thereunder to Lessor
or to the holders of mortgages or deeds of trust on the Premises. A stipulated
value or agreed amount endorsement deleting the coinsurance provision of the
policy shall be procured with said insurance as well as an automatic increase in
insurance endorsement, causing the increase in annual property insurance
coverage by 1% per quarter, or as may be determined from time to time as based
on the cumulative change in CPI, from Lease Commencement. If Lessor shall fail
to procure and maintain said insurance, the Lessee may, but shall not be
required to, procure and maintain the same, but at the expense of Lessee. If
such insurance coverage has a deductible clause, the deductible. amount shall
not exceed $5,000 per occurrence, and Lessee shall be liable for such deductible
amount, in the same proportion as Lessee is liable for the cost of insurance
under the formula set forth above.

          (b)  The Lessor shall, in addition, obtain and keep in force at
Lessee's expense during the term of this Lease, a policy of rental value
insurance (Loss of Rents) covering a period of one year, with loss payable to
Lessor which insurance shall also cover all real estate taxes and insurance
costs for said period.

          (c)  If the Premises are part of a larger building, or if the Premises
are part of a group of buildings owned by Lessor which are adjacent to the
Premises, then Lessee shall pay for any increase in the property insurance of
such other building or buildings if said increase is caused by Lessee's acts,
omissions, or use of occupancy of the Premises.

          (d)  If the Lessor is the insuring party, the Lessor will not insure
Lessee's fixtures, equipment, or tenant improvements unless the tenant
improvements have become a part of the Premises under Paragraph 7 hereof.

                                    - 10 -
<PAGE>
 
Lessee shall insure its fixtures, equipment, and tenant improvements which have
not become a part of the Premises.

          8.4  INSURANCE POLICIES. The insuring party shall deliver to the other
party, copies of policies or such insurance certificates evidencing the
existence and amounts of such insurance, with loss payable clauses as required
by this Paragraph 8. No such policy shall be cancellable or subject to reduction
of coverage, or other modification, except after thirty (30) days prior written
notice to Lessor. If Lessee is the insuring party, Lessee shall at least (30)
days prior to the expiration of such policies, furnish Lessor with renewals or
"binders" thereof, or Lessor may order such insurance and charge the cost
thereof to Lessee, which amount shall be payable by Lessee upon demand. Lessee
shall not do, or permit to be done, anything which shall invalidate the
insurance policies referred to in Paragraph 8.3. If Lessee does or permits to be
done, anything which shall increase the cost of the insurance policies referred
to in Paragraph 8.3, then Lessee shall forthwith upon Lessor's demand, reimburse
Lessor for any additional premiums attributable to any act or omission of
operation of Lessee causing such increase in the cost of insurance. If Lessor is
the insuring party, and if the insurance policies maintained hereunder cover
other improvements, in addition to the Premises, Lessor shall deliver to Lessee
a written statement setting forth the amount of any such insurance cost increase
and showing in reasonable detail the manner in which it has been computed.
Insurance required hereunder shall be with companies holding a "General
Policyholders Rating" of at least B plus, or such other rating as may be
required by a lender having a lien on the Premises, as set forth in the most
current issue of "Best's Insurance Guide".

          8.5  WAIVER OF SUBROGATION. Lessee and Lessor each hereby release and
relieve the other, and waive their entire right of recovery against the other
for loss or damage arising out of or incident to the perils required to be
insured against hereunder, which perils occur in, on, or about the Premises,
whether due to the negligence of Lessor or Lessee or their agents, employees,
contractors and/or invitees. Lessee and Lessor shall, upon obtaining the
policies of insurance required hereunder, give notice to the insurance carrier
or carriers that the foregoing mutual waiver of subrogation is contained in this
Lease.

          8.6  INDEMNITY. Lessee shall indemnify and hold harmless Lessor from
and against any and all claims arising from Lessee's use of the Premises, or
from the conduct of Lessee's business, or from activity, work or other things
done, permitted or suffered by Lessee in or about the Premises, or upon the real
property where such Premises are located and shall further indemnify and hold
harmless Lessor from and against any and all claims arising from any breach or
default in the performance of any obligation on Lessee's part to be performed
under the terms of this Lease, or arising from any negligence of the Lessee or
any of Lessee's agents, contractors or employees, and from and against all
costs, attorneys' fees, expenses and liabilities incurred thereon; and in case
any action or proceeding be brought against Lessor by reason of any such claim.
Lessee, upon notice from Lessor, shall defend the same at Lessee's expense.
Lessee, as a material part of the consideration of Lessor, hereby assumes all
risks of damage to property or injury to persons in, upon or about Premises,
arising from any cause, except for any loss, or claim attributable to a breach
of this Lease on the part of the Lessor, or an

                                    - 11 -
<PAGE>
 
intentional act of coumission or an intentional act of omission or a negligent
act of omission or commission on the part of Lessor, Lessor's employees, agents
or contractors, from which Lessor shall defend, indemnify and hold harmless
Lessee.

          8.7  EXEMPTION OF LESSOR FROM LIABILITY. Lessee hereby agrees that
Lessor shall not be liable for injury to Lessee's business or any loss of
income therefrom, or for damages to the goods, wares, merchandise or other
property of Lessee, Lessee's employees, invitees, customers, or any other person
in or about the Premises, nor shall Lessor be liable for injury to the person of
Lessee, Lessee's employees, agents or contractors (except as may be caused by
negligence by engineering design), and whether such damage or injury is caused
by or results from fire, steam, electricity, gas, water or rain, or from the
breakage, leakage, obstruction or other defects of pipes, sprinklers, wires,
appliances, plumbing, mechanical systems, or lighting fixtures, or from any
other cause, whether the said damage or injury results from conditions arising
upon the Premises, or upon other portions of the building of which the Premises
are a part, or from other sources or places unless the cause of such damage or
injury or the means of repairing the same is inaccessible to Lessee. In
connection with Lessor's repairs, alterations, replacements or improvements to
the Premises, Lessor shall not suspend any utility services to the Premises
during Lessee's normal business hours, except as may be necessary in an
emergency. Lessor shall not be liable for any damages arising from any act or
neglect of any other tenant, if any, of the building in which the Premises are
located.

     9.   DAMAGE OR DESTRUCTION.

          9.1  Definitions.

               (a)  If at any time during the last eight months of the term of
this Lease, or an extended term of this Lease, there is damage, whether or not

and Lessor or Lessee repairs or restores the Premises, pursuant to the
provisions of this Paragraph 9, the rent payable hereunder for the period during
which such damage, repair or restoration continues shall be abated in proportion
to the degree to which Lessee's use of the Premises is impaired. Except for
abatement of rent, if any, Lessee shall have no claim against Lessor for any
damage suffered by reason of any such damage, destruction, repair or 
restoration.

               (b)  If Lessor shall be obligated to repair or restore the
Premises under the provisions of this Paragraph 9, and shall not commence such
repair or restoration within 60 days after such obligations shall accrue, Lessee
may at Lessee's option cancel and terminate this Lease by giving Lessor written
notice of Lessee's election to do so at any time prior to the commencement of
such repair or restoration. In such event, this Lease shall terminate as of the
date of such notice.

          9.7  TERMINATION - Advance Payments. Upon termination of this Lease
pursuant to this Paragraph 9, an equitable adjustment shall be made concerning
advance Rent payments made by Lessee to Lessor.

          9.8  WAIVER.  Lessor and Lessee waive the provisions of any statutes
which relate to termination of leases when leased property is destroyed and
agree that such event shall be governed by the terms of this Lease.

     10.  REAL PROPERTY TAXES.

          10.1  PAYMENT OF TAXES. Beginning upon the date of Commencement of the
Lease, Lessee shall pay the real property tax, as defined in Paragraph 10.2,
applicable to the square footage leased by Tenant as a portion of the total
Premises during the term of this Lease. All such payments shall be made at least
ten (10) days prior to the delinquency date of such payment. Lessee shall
promptly furnish Lessor with satisfactory evidence that such taxes have been
paid. If any such taxes paid by Lessee shall cover any period of time prior to
or after the expiration of the term hereof, Lessee's share of such taxes shall
be equitably prorated to cover only the period of time within the tax fiscal
year during which this Lease shall be in effect, and Lessor shall reimburse
Lessee to the extent required. If Lessee shall fail to pay any such taxes,
Lessor shall have the right to pay the same, in which case Lessee shall repay
such amount to Lessor with Lessee's next rent installment, together with any
penalties and interest imposed by the taxing authority, plus default interest
pursuant to Section 19.

          The real property tax that Lessee will be required to pay under this
provision will be that portion of the real property taxes on the real property
and the building located thereon, as set forth in Exhibits "A" and "B", which is
occupied by Lessee, and the ratio shall be determined by the number of square
feet leased by Lessee that bears to the total number of square feet of leasable
space in the entire building. If any additional improvements are made to a
portion of the building not occupied by the Lessee, any increase in taxes
attributable to such addition will be the liability of someone other than Lessee
under this Lease.  If Lessor installs additional improvements upon the real
property in addition to the building in which Lessee is located, then the amount
of taxes that will be required to be paid by Lessee shall be in a ratio that is
determined by the number of square feet occupied by Lessee, as that bears to the
total number of square feet of revised building area and improvements on the
real property.

          If Lessor is required to pay impounds for taxes to any lending
institution holding a lien on the real property, Lessee will pay his
proportionate share of such impounds, based upon the ratio as above described,
as and when required to be paid by Lessor, under the Deed of Trust or mortgage
securing the Lessee.

          The Lessee reserves the right to appeal directly or assist in the
appeal process of the assessment of Property Taxes, by the governing authority.

          10.2 DEFINITION of Real Property Tax. As used herein, the term
"real property tax" shall include any form of real estate tax or assessment,
general, special, ordinary or extraordinary, and any license fee, commercial
rental tax, improvement bond or bonds, levy or tax (other than inheritance,
personal income or estate taxes) imposed on the Premises by any authority having
the direct or indirect power to tax, including any city, state or federal
government, or any school, agricultural, sanitary, fire, street, drainage or
other improvement district thereof, as against any legal or equitable interest
of Lessor in the Premises or in the real property of which the Premises are a
part, as against Lessor's right to rent or derive other income therefrom, and as
against Lessor's business of leasing the Premises;

                                     - 15 -
<PAGE>
 
provided, however, that with respect to any special assessments which may be
paid in a lump sum or in periodic installments, Lessee shall only be required to
pay such assessments in periodic installments and only for the remainder of the
Term, as may be extended. The term "real property tax" shall also include any
tax, fee, levy, assessment or charge (i) in substitution of, partially or
totally, any tax, fee, levy, assessment, or charge hereabove included within the
definition of "real property tax", or (ii) the nature of which was hereinbefore
included within the definition of "real property tax", or (iii) which is imposed
for a service or right not charged prior to August, 1990, or, if previously
charged, has been increased since August, 1990, or (iv) which is imposed as a
result of a transfer, either partial or total, of Lessor's interest in the
Premises or which is added to a tax or charge hereinbefore included within the
definition of real property by reason of such transfer (except for any sales tax
on a transfer of the property), or (v) which is imposed by reason of this
transaction, any modifications or changes hereto, or any transfers hereof.

          10.3  JOINT ASSESSMENT. If the Premises are not separately Lessee's
liability shall be a portion of the real property taxes for land and
improvements included within the tax parcel assessed.

          The amount of taxes to be paid by Lessee shall be an amount based upon
the ratio of the number of square feet of the building included in the Premises
occupied by the Lessee as that bears to the total amount of area within the
building that is available for use by Lessor or another tenant. If additional
improvements are placed upon the land whereon the building is located from which
the Premises are delineated, any increase in taxes by reason of such
improvements shall not be a liability of Lessee unless such improvement is
placed specifically upon that portion of the building constituting a part of the
Premises which is occupied by the Lessee, in which event Lessee will pay for all
such additional taxes.
                                                            
          10.4  PERSONAL PROPERTY TAXES.

                (a) Lessee shall pay, prior to delinquency, all taxes assessed
against and levied upon trade fixtures, furnishings, equipment and all other
personal property of Lessee contained in the Premises or elsewhere. When
possible, Lessee shall cause said trade fixtures, furnishings, equipment and all
other personal property to be assessed and billed separately from the real
property of Lessor.

                (b) If any of Lessee's said personal property shall be assessed
with Lessor's real property, Lessee shall pay Lessor the taxes attributable to
Lessee within 10 days after receipt of a written statement setting forth the
taxes applicable to Lessee's property.

     11.  UTILITIES. Lessee shall pay directly to the appropriate agency, for 
all water, gas, heat, light, power, telephone and other utilities and services
supplied to the Premises, together with any taxes thereon. If any such services
are not separately metered to Lessee, Lessee shall pay a reasonable proportion,
as determined by Lessor, of all charges jointly metered with other premises.
 
     12.  ASSIGNMENT AND SUBLETTING. 

                                     - 16 -
<PAGE>
 
          12.1  LESSOR' S CONSENT REQUIRED. Lessee shall not voluntarily or by
operation of law, assign, transfer, mortgage, sublet, or otherwise transfer or
encumber all or any part of Lessee's interest in this Lease or in the Premises,
without Lessor's prior written consent, which Lessor shall not unreasonably
withhold. Lessor shall respond to Lessee's request for consent hereunder within
fifteen (15) days after Lessor's receipt of Lessee's request therefor, and in
the event Lessor fails to respond within said 15-day period, Lessor shall be
deemed to have consented to such assignment or sublease. Any attempted
assignment, transfer, mortgage, encumbrance or subletting without such consent
shall be void, and shall constitute a breach of this Lease.

          12.2  LESSEE AFFILIATE. Notwithstanding the provisions of Paragraph

12.1 hereof, Lessee may assign or sublet the Premises, or any portion
thereof, without Lessor's consent, to any corporation, partnership, or other
entity, which controls, is controlled by or is under common control with Lessee,
or to any corporation, partnership, or other entity, resulting from merger or
consolidation with Lessee, or to any person or entity which acquires all the
assets of Lessee as a going concern of the business that is being conducted on
the Premises, provided that said assignee assumes, in full, the obligations of
Lessee under this Lease. Any such assignment shall not, in any way, affect or
limit the liability of Lessee under the terms of this Lease even if after such
assignment or subletting, the terms of this Lease are materially changed or
altered with the consent of Lessee, the consent of whom shall not be necessary.

          12.3  NO RELEASE OF LESSEE.  Regardless of Lessor's consent, no
subletting or assignment shall release Lessee of Lessee's obligation or alter
the primary liability of Lessee to pay the rent and to perform all other
obligations to be performed by Lessee hereunder. The acceptance of rent by
Lessor from any other person shall not be deemed to be waiver by Lessor or any
provision hereof. Consent to assignment or subletting shall not be deemed
consent to any subsequent assignment or subletting. In the event of default by
any assignee of Lessee or any successor of Lessee, in the performance of the
terms hereof, Lessor may proceed directly against Lessee without the necessity
of exhausting remedies against said assignee. Lessor may consent to subsequent
assignments or subletting of this Lease or amendments or modifications to this
Lease with assignees of Lessee, and without obtaining its or their consent
thereto and such action shall not relieve Lessee of liability under this Lease;
provided that Lessor delivers written notice of such subsequent assignment,
sublease, amendment or modification to Lessee.

     If there is an assignment or subletting of the rights under this Lease
with the consent of Lessor, and thereafter a default occurs on the part of such
assignee, Lessor shall give Lessee notice of such default, and Lessee shall have
ten days within which to cure or commence to cure such default before this Lease
shall be terminated.

     12.4 ATTORNEYS' FEES.  In the event Lessee shall assign or sublet the
Premises or request the consent of Lessor to any assignment or subletting, or if
Lessee shall request the consent of Lessor for any act Lessee proposes to do,
then Lessee shall pay Lessor's reasonable attorneys' fees incurred in connection
therewith, such attorneys' fees not to exceed $1,000 for each such request.

                                     - 17 -
<PAGE>
 
     13.  DEFAULTS; REMEDIES.

          13.1  DEFAULTS. The occurrence of any one or more of the following
events shall constitute a material default and breach of this Lease by Lessee.

                (a) The vacating or abandonment of the Premises by the Lessee,
provided however, that if Lessee continues to pay the rent and other amounts
required under this Lease, such abandonment or vacating will not constitute a
default.

                (b) The failure by Lessee to make any payment of rent or any
other payment required to be made by Lessee hereunder, as and when due, where
such failure shall continue for a period of ten (10) days after receipt of
written notice thereof from Lessor to Lessee. In the event that Lessor serves
with a Notice to Pay Rent or Quit pursuant to applicable unlawful detainer
statutes, such Notice to Pay Rent or Quit shall also constitute the notice
required by this subparagraph.

                (c) The failure by Lessee to observe or perform any of the
covenants, conditions or provisions of this lease to be observed or performed by
Lessee, other than described in Paragraph (b) above, where such failure shall
continue for a period of 30 days after written notice thereof from Lessor to
Lessee; provided, however, that if the nature of Lessee's default is such that
more than 30 days are reasonably required for its cure, then Lessee shall not be
deemed to be in default if Lessee commenced such cure within said 30 day period
and thereafter diligently prosecutes such cure to completion.

                (d) (i) The making by Lessee of any general arrangement or
assignment for the benefit of creditors; (ii) Lessee becomes a "debtor" as
defined in U.S.C. 101, or any successor statute thereto (unless, in the case of
a petition filed against Lessee, the same is dismissed within 60 days) (iii) the
appointment of a trustee or receiver to take possession of substantially all of
Lessee's assets located at the Premises or of Lessee's interest in this Lease,
where possession is not by execution or other judicial seizure of substantially
all of Lessee's assets located at the Premises or of Lessee's interest in this
Lease, where such seizure is not discharged within 30 days. Provided, however,
in the event that any provision of this Paragraph 13.1 (d) is contrary to any
applicable law, such provision shall be of no force or effect.

                (e) The discovery by Lessor that any financial statement given
to Lessor by Lessee was materially false at the time given to Lessor; provided
however, that Lessee had actual knowledge of the existence of such falsity and
that such materially false financial statement shall not constitute a default so
long as Lessee remains liable under the terms of this Lease and continues to pay
all amounts required to be paid by Lessee under the terms of this Lease.

          13.2  REMEDIES. In the event of any such material default or breach by
Lessee, Lessor may at any time thereafter, without notice or demand and without
limiting Lessor in the exercise of any right or remedy which Lessor may have by
reason of such default or breach, choose any or all of the following:

                                     - 18 -
<PAGE>
 
                (a) Terminate Lessee's right to possession of the Premises by
any lawful means, in which case this Lease shall terminate, and Lessee shall
immediately surrender possession of the Premises to Lessor. In such event,
Lessor shall be entitled to recover from Lessee all damages incurred by Lessor
by reason of Lessee's default including, but not limited to, the cost of
recovering possession of the Premises; expenses of reletting, including
necessary renovation and alteration of the Premises, reasonable attorneys' fees,
that portion of the leasing commission paid by Lessor pursuant to Paragraph 15,
applicable to the unexpired term of this Lease.

                (b) Maintain Lessee's right to possession in which case this
Lease shall continue in effect whether or not Lessee shall have abandoned the
Premises. In such event, Lessor shall be entitled to enforce all of Lessor's
rights and remedies under this Lease, including the right to recover the rent as
it becomes due hereunder.

                (c) Pursue any other remedy now or hereafter available to Lessor
under the laws or judicial decisions of the state wherein the Premises are
located. Unpaid installments of rent and other monetary obligations of Lessee
under the terms of this Lease shall bear interest from the date due at the
maximum rate than allowable by law.

          13.3  DEFAULT BY LESSOR. Lessor shall not be in default unless Lessor 
fails to perform obligations required of Lessor within a reasonable time, but in
no event later than ten (10) days after receipt of written notice by Lessee to
Lessor, and to the holder of any first mortgage or deed of trust covering the
Premises whose name and address shall have theretofore been furnished to Lessee
in writing, specifying wherein Lessor has failed to perform such obligation;
provided, however, that if the nature of Lessor's obligation is such that more
than thirty (30) days are required for performance, then Lessor shall not be in
default if Lessor commences action within such 30 day period and thereafter
diligently prosecutes the same to completion.

          Notwithstanding any other provision in this Lease to the contrary or
which provides separate and/or additional remedies for Lessee, in the event
Lessor fails to perform its obligations or fails to initiate performance of its
obligations within said 30-day period, Lessee shall have the right, but not the
obligation, to perform Lessor's obligations, the cost of which shall either be
paid to Lessee by Lessor immediately upon demand therefor, or an offset against
future rentals. In the event Lessee elects not to cure Lessor's failure to
perform and Lessor's failure continues for thirty (30) days after Lessor's
receipt of Lessee's notice, Lessee shall have the right to terminate this Lease
effective immediately upon delivery of written notice of such termination to
Lessor. In the event of such termination by Lessee, each party shall be relieved
of all respective duties and obligations hereunder.
 
          13.4  LATE CHARGES. Lessee hereby acknowledges that late payment by
Lessee to Lessor of rent and other sums due hereunder will cause Lessor to incur
costs not contemplated by this Lease, the exact amount of which will be
difficult to ascertain. Such costs include, but are not limited to, processing
and accounting charges, and late charges which may be imposed on Lessor by the
terms of any mortgage or trust deed covering the Premises. Accordingly, if any
installment of rent or any other sum due from Lessee shall

                                     - 19 -
<PAGE>
 
 not be received by Lessor or Lessor's designee within ten (10) days after such
 amount shall be due, then, without any requirement for notice to Lessee, Lessee
 shall pay to Lessor a LATE CHARGE equal to the late charge imposed by any
 lender of Lessor in connection with the Premises, or 5%, whichever is less, of
 such overdue amount. The parties hereby agree that such LATE CHARGE represents
 a fair and reasonable estimate of the costs Lessor will incur by reason of late
 payment by Lessee. Acceptance of such late charge by Lessor shall in no event
 constitute a waiver of Lessee's default with respect to such overdue amount,
 nor prevent Lessor from exercising any of the other rights and remedies granted
 hereunder.

          13.5  IMPOUNDS. If a late charge is payable hereunder, whether or not
collected, for three (3) consecutive installments of rent, within any Lease
Term, or any other monetary obligations of Lessee under the terms of this Lease,
Lessee shall pay to Lessor, in addition to any other payments required under
this Lease, a monthly advance installment, payable at the same time as the
monthly rent, for real property taxes and insurance expenses on the Premises,
which are payable by Lessee to Lessor under the terms of this Lease. Such
monthly impound shall be an amount equal to 1/12 of the real property tax for
the last taxable year, and 1/12 of the insurance premium for the preceding
insurance year during which insurance premiums were paid for the insurance
required to be paid for by Lessee under the terms of this Lease. Such funds
shall be established to insure payment when due before delinquency of any and
all such real property taxes and insurance premiums. If the amounts paid to
Lessor by Lessee under the provisions of this Paragraph 13.5 are insufficient to
discharge the obligations of Lessee to pay such real property taxes and
insurance premiums as the same become due, Lessee shall pay to Lessor, upon
Lessor's demand, such additional sums necessary to pay such obligations. All
monies paid to Lessor under this Paragraph 13.5 may be intermingled with other
monies of Lessor and shall not bear interest. In the event of a default in the
obligation of Lessee to perform under this Lease, then any balance remaining
from the funds paid to Lessor under the provisions of this Paragraph 13.5, may
at the option of Lessor be applied to payment of any monetary default of Lessee
in lieu of being applied to the payment of real property tax and insurance
premiums.

          14.   CONDEMNATION. If the Premises or any portion thereof are taken
under the power of eminent domain, or sold under the threat of the exercise of
said power (all of which are herein called "condemnation"), and such
condemnation renders the Premises unsuitable for Lessee's use, as reasonably
determined by Lessee, this Lease shall terminate as to the part so taken as of
the date of condemning authority takes title or possession, whichever first
occurs. If more than 10% of the floor area of the building on the Premises, or
more than 25% of the land area of the Premises, or a majority of the parking
area designated for Lessee's use, which is not occupied by any building, is
taken by condemnation, or if such condemnation renders the Premises unsuitable
for Lessee's use or adversely affects Lessee's use of the Premises, as
reasonably determined by Lessee, Lessee may at Lessee's option, to be exercised
in writing only within ten (10) days after Lessee's receipt of written notice of
such taking (or in the absence of such notice, within (10) days after the
condemning authority shall have taken possession) terminate this Lease as of the
date the condemning authority takes such possession. If Lessee does not
terminate this Lease in accordance with the foregoing, this Lease shall remain
in full force and effect as to the portion of the Premises

                                     - 20 -
<PAGE>
 
remaining, except that the rent shall be reduced in the proportion that the
floor area of the building taken bears to the total floor area of the building
constituting the Premises. Any award for the taking of all or any part of the
Premises under which the power of eminent domain or any payment made under
threat of the exercise of such power shall be the property of Lessor, whether
such award shall be made as compensation for diminution in value of the
leasehold or for the taking of the fee, or as severance damages; provided,
however, that Lessee shall be entitled to any award for loss of or damage to
Lessee's trade fixtures and removable personal property. In the event that this
Lease is not terminated by reason of such condemnation, Lessor shall, in the
exercise of due diligence, repair any damage to the Premises caused by such
condemnation except to the extent that Lessee has been reimbursed therefor by
the condemning authority.

          15.   BROKER'S FEE.

                (a) Upon the execution of this Lease by both parties, Lessor
shall be responsible for all Broker's Fees connected with this Lease, and in
accord with separate agreement(s) for same. This paragraph is set forth for
information purposes only, and has no binding obligation on the part of Lessee.

          16.   ESTOPPEL CERTIFICATE.

                (a) Lessee shall at any time, within fifteen (15) days after
written notice from Lessor, execute, acknowledge and deliver to lessor a
statement in writing (i) certifying that this Lease is unmodified and in full
force and effect (or, if modified, stating the nature of such modification and
certifying that this Lease, as so modified, is in full force and effect) and the
date to which the rent and other charges are paid in advance if any, and (ii)
acknowledging that there are not, to Lessee's knowledge, any uncured defaults
if any are claimed. Any such statement may be conclusively relied upon by any
prospective purchaser or encumbrancer of the Premises.

                (b) At Lessor's option, Lessee's failure to deliver such
statement within such time shall be conclusive upon Lessee (i) that this Lease
is in full force and effect, without modification except as may be represented
by Lessor, (ii) that there are no uncured defaults in Lessor's performance, and
(iii) that not more than one month's rent has been paid in advance.

                (c) If Lessor desires to finance, refinance, or sell the
Premises, or any part thereof, Lessee hereby agrees to deliver to any lender or
purchaser designated by Lessor, such financial statements of Lessee as may be
reasonably required by such lender or purchaser. Such statements shall include
the past three years' financial statements of Lessee. All such financial
statements shall be received by Lessor, such lender or purchaser in confidence
and shall be used only for the purposes herein set forth.

          17.   LESSOR'S LIABILITY

                The term "Lessor" as used herein shall mean only the owner or
owners at the time in question of the fee title or a Lessee's interest in a
ground Lease of the Premises, and except as expressly provided in Paragraph 15,
in the event of any transfer of such title or interest, Lessor herein

                                     - 21 -
<PAGE>
 
named (and in case of any subsequent transfers then the grantor) shall be
relieved from and after the obligations thereafter to be performed, provided
that any funds in the hands of Lessor or the then grantor at the time of such
transfer, in which Lessee has an interest, shall be delivered to the grantee.
The obligations contained in this Lease to be performed by Lessor shall, subject
as aforesaid, be binding on Lessor's successors and assigns, only during their
respective periods of ownership.

          18.   SEVERABILITY. The invalidity of any provision of this Lease is
determined by a court of competent jurisdiction, shall in no way affect the
validity of any other provision hereof.

          19.   INTEREST ON PAST DUE OBLIGATIONS.  Except as expressly herein
provided, any amount due to Lessor not paid when due shall bear interest at the
rate equal to First Interstate Bank of Arizona's "Prime Rate" as announced from
time to time, plus 2%, from the due date. Payment of such interest shall not
excuse or cure any default by Lessee under this Lease, provided however, that
interest shall not be payable on late charges incurred by Lessee nor on any
amounts upon which late charges are paid by Lessee.

          20.   TIME IS OF THE ESSENCE.  Time is of the essence.

          21.   ADDITIONAL RENT.  Any monetary obligations of Lessee to Lessor
under the terms of this Lease shall be deemed to be rent.

          22.   INCORPORATION OF PRIOR AGREEMENTS; AMENDMENTS.
                This Lease, including the Exhibits attached hereto, contains all
agreements of the parties with respect to any matter mentioned herein. No prior
agreement or understanding pertaining to any such matter shall be effective,
except for Lease Proposal Documents and letters, which are incorporated herein
by reference. This Lease may be modified in writing only, signed by the parties
in interest at the time of the modification. Except as otherwise stated in this
Lease, Lessee hereby ackknowledges that neither the real estate broker listed in
Paragraph 15 hereof, nor any cooperating broker on this transaction, nor the
Lessor or any employees or agents of any of said person has made any oral or
written warranties or representations to Lessee relative to the condition or use
by Lessee of said Premises, and Lessee acknowledges that Lessee assumes all
responsibility regarding the Occupational Safety Health Act, the legal use and
adaptability of the Premises and the compliance thereof with all applicable laws
and regulations in effect during the term of this Lease except as otherwise
specifically stated in this Lease.

          23.   NOTICES. Any notice required or permitted to be given hereunder
shall be in writing and may be given by personal delivery, certified mail, or
overnight delivery, and if given personally or by mail, shall be deemed
sufficiently given if addressed to Lessee or to Lessor at the address noted
below the signature of the respective parties, as the case may be. Either party
may by notice to the other specify a different address for notice purposes.  A
copy of all notices required or permitted to be given to Lessor hereunder shall
be concurrently transmitted to such party or parties at such addresses as Lessor
may from time to time hereafter designate by notice to Lessee.

          The notices herein provided for shall be deemed given upon the date

                                     - 22 -

the personal delivery is made, and a receipt for such notice is signed by an
authorized agent of Lessor or Lessee. If notice is given by certified mail, it
shall be return receipt requested, and shall be deemed given upon the date
indicated as having been delivered by the United States Postal Department on the
return receipt.

          Notices to LESSEE shall be sent to:

          24.   WAIVERS. No waiver by Lessor of any provision hereof shall be
deemed a waiver of any other provision hereof or of any subsequent breach by
Lessee of the same or any other provision. Lessor's consent to or approval of
any act shall not be deemed to render unnecessary the obtaining of Lessor's
consent to or approval of any subsequent act by Lessee. The acceptance of rent
hereunder by Lessor shall not be a waiver of any preceding breach by Lessee of
any provision hereof, other than the failure of Lessee to pay the particular
rent so accepted, regardless of Lessor's knowledge of such preceding breach at
the time of acceptance of such rent.

          25.   RECORDING. Either Lessor or Lessee shall, upon request of the
other, execute, acknowledge and deliver to the other a "short form" memorandum
of this Lease for recording purposes.

          26.   HOLDING OVER. If Lessee, with Lessor's consent, remains in
possession of the Premises or any part thereof after the expiration of the term
hereof, or the extended term, such occupancy shall be a tenancy from month to
month upon all the provisions of this Lease pertaining to the obligations of
Lessee, but all options and rights of first refusal, if any, granted under the
terms of this Lease shall be deemed terminated and be of no further effect
during said month to month tenancy.

          27.   CUMULATIVE REMEDIES. No remedy or election hereunder shall be
deemed exclusive but shall, wherever possible, be cumulative with all other
remedies at law or in equity.

          28.   COVENANTS AND CONDITIONS. Each provision of this Lease per-
formable by Lessee and Lessor shall be deemed both a covenant and a condition.

          29.   BINDING EFFECT; CHOICE OF LAW.  Subject to any provisions hereof
restricting assignment or subletting by Lessee and subject to the provisions of
Paragraph 17, this Lease shall bind the parties, their personal representatives,
successors and assigns. This Lease shall be governed by the laws of the State
wherein the Premises are located.

          30.   SUBORDINATION.

          (a) This Lease, at Lessor's option, shall be subordinate to any

                                     - 23 -
<PAGE>
 
ground lease, mortgage, deed of trust, or any other hypothecation or security
now or hereafter placed upon the real property of which the Premises are a part
and to any and all advances made on the security thereof and to all renewals,
modifications, consolidations, replacements and extensions thereof.
Notwithstanding such subordination, Lessee's right to quiet possession of the
Premises shall not be disturbed if Lessee is not in default and so long as
Lessee shall pay the rent and observe and perform all of the provisions of this
Lease, unless this Lease is otherwise terminated pursuant to its terms. If any
mortgagee, trustee or ground lessor shall elect to have this lease assigned, the
Lessor shall give written notice thereof to Lessee, this Lease shall be deemed
prior to such mortgage, deed of trust or ground lease, whether this Lease is
dated prior or subsequent to the date of said mortgage, deed of trust or ground
lease or the date of recording thereof. Upon any subordination, the Lessee
hereunder shall continue to be entitled to peaceable possession of the Premises
so long as Lessee is not in default under any of the terms of this Lease.

          (b) Lessee agrees to execute any documents reasonably required to
effectuate an attornment, a subordination or to make this Lease prior to the
lien of any mortgage, deed of trust or ground lease, as the case may be.
Lessee's failure to execute such documents within 10 days after receipt of
written demand shall constitute a material default by Lessee hereunder, unless
the subordination agreement or document does not provide for the continued
peaceable possession of Lessee when not in default under the terms of this
Lease.

          31.  ATTORNEY'S FEES.  If either party named herein brings an action
to enforce the terms hereof or declare rights hereunder, the prevailing party in
any such action, on trial or appeal, shall be entitled to his reasonable
attorney's fees to be paid by the losing party as fixed by the court.

          32.  LESSOR 'S ACCESS. Lessor and Lessor's agents shall have the
right to enter the Premises at reasonable times and for upon twenty-four (24)
hours' prior notice to Lessee, or as otherwise agreed to from time to time
between the parties, for the purpose of inspecting of the same, showing the same
to lenders, prospective purchasers, or prospective lessees, and making such
alterations, repairs, improvements or additions to the Premises as Lessor may
deem necessary or desirable. Lessor may not at any time place on or about the
Premises any ordinary "For Sale" signs; without receiving prior written
permission from Lessee, Lessor may at any time during the last 180 days of the
term or extended term hereof place on or about the Premises any ordinary "For
Lease" signs, without receiving prior written permission from Lessee.

          33.  AUCTIONS. Lessee shall not conduct, nor permit to be conducted,
either voluntarily or involuntarily, any auction upon the Premises without first
having obtained Lessor's prior written consent. Notwithstanding anything to the
contrary in the Lease, Lessor shall not be obligated to exercise any standard of
reasonableness in determining whether to grant such consent.

          34.  SIGNS.  Lessee shall not place any sign upon the Premises
without Lessor's prior written consent, which shall not unreasonably be
withheld, if in conformity with sign ordinances applicable thereto, and
commensurate with the tenant's signs located on the property and in the
neighborhood,

                                     - 24 -
<PAGE>
 
except that Lessee shall have the right without the prior permission of Lessor,
to place ordinary and usual For Rent or Sublet signs thereon.

          35.  CONSENTS. Wherever in this Lease the consent of one party is
required to an act of the other party, such consent shall not be unreasonably
withheld or delayed.

          36.  GUARANTOR. In the event that there is a guarantor of this Lease,
an addendum or modification to the Lease, defining the scope and/or limitations
of the guarantor, shall be set forth.

          37.  QUIET SESSION. Upon Lessee paying the rent for the Premises and
observing and performing all of the covenants, conditions and provisions on
Lessee's part to be observed and performed hereunder, Lessee shall have quiet
possession of the Premises for the entire term hereof, and extended term,
subject to all of the provisions of this Lease. The individual(s) executing this
Lease on behalf of Lessor, represent and warrant to Lessee that they are fully
authorized and legally capable of executing this Lease on behalf of Lessor and
that such execution is binding upon all parties holding an ownership interest in
the Premises.

          38.  OPTIONS.

               38.1 DEFINITION. As used in this paragraph the word "OPTIONS" has
the following meaning: (1) the right or option to extend the term of this Lease
or to renew this Lease or to extend or renew any lease that Lessee has on other
property of Lessor; (2) the option or right of first refusal to lease, or right
of first refusal to lease the Premises, or the right of first offer to lease the
Premises, or the right of first refusal to lease other property of Lessor or
the right of first offer to lease other property of Lessor.

               38.2  OPTIONS ASSIGNABLE ONLY WITH ASSIGNMENT OF LEASE. Each
Option granted to Lessee in this Lease are personal to Lessee and may not be
exercised or be assigned, voluntarily or involuntarily, by or to any person or
entity other than Lessee, provided however, the Option may be exercised by or
assigned to any assignee of Lessee approved by Lessor, pursuant to Paragraph
12.1 of this Lease, or by any Lessee Affiliate as defined in Paragraph 12.2 of
this Lease. The Options herein granted to Lessee are not assignable separate and
apart from this Lease.

               38.3  MULTIPLE OPTIONS. In the event that Lessee has any multiple
options to extend or renew this Lease, a later option cannot be exercised unless
the prior option to extend or renew this Lease has been so exercised.

          38.  EFFECT OF DEFAULT ON OPTIONS.

               (a) Lessee shall have no right to exercise an Option,
notwithstanding any provision in the grant of Option to the contrary, (i) during
the time commencing from the date Lessor gives to Lessee a notice of default
pursuant to Paragraph 13.1 (b) or 13.1 (c) and continuing until the default
alleged in said notice of default is cured, or (ii) during the period of time
commencing on the day after a monetary obligation to Lessor is due

                                     - 25 -
<PAGE>
 
from Lessee and unpaid and continuing until the obligation is paid, or (iii) at
any time after an event of default described in Paragraphs 13.1 (a), 13.1 (d),
or 13.1 (e) (without any necessity of Lessor to give notice of such default to
Lessee).

                (b) The period of time within which an Option may be exercised
shall not be extended or enlarged by reason of Lessee's inability to exercise
an Option because of the provisions of Paragraph 39.4 (a).

                (c) All rights of Lessee under the provisions of an Option shall
terminate and be of no further force or effect, notwithstanding Lessee's due and
timely exercise of the Option, if, after such exercise and during the term of
this Lease, (i) Lessee fails to pay to Lessor a monetary obligation of Lessee
for a period of 30 days after such obligation becomes due, or (ii) Lessee fails
to commence to cure a default specified in Paragraph 13.1 (c) within 30 days
after the date that Lessor gives notice to Lessee of such default and/or Lessee
fails thereafter to diligently prosecute said cure to completion, or (iii)
Lessee commits a default described in Paragraph 13.1 (a), 13.1 (d), or 13.1 (e)
(without the necessity of Lessor to give notice of such default to Lessee), or
(iv) Lessor gives to Lessee three or more notices of default under Paragraph
13.1 (b), where a late charge becomes payable under Paragraph 13.4 for each
such default, or Paragraph 13.1 (c), except where the defaults are cured.

          39.  MULTIPLE TENANT BUILDING. In the event that the Premises are part
of a larger building or group of buildings, then Lessee agrees that it will
abide by, keep and observe all reasonable rules and regulations which Lessor may
make from time to time for the management, safety, care, and cleanliness of the
building and grounds, the parking of vehicles and the preservation of good order
therein as well as for the convenience of other occupants and tenants of the
building; provided, however, that any such Rules and Regulations must apply
uniformly to all tenants in the building and, provided further, that such Rules
and Regulations do not abrogate in any way Lessee's rights under this Lease. The
material violation of any such rules and regulations shall be deemed a material
breach of this Lease by Lessee. If Lessor deems Lessee in breach of this
Paragraph 40, notice of such breach shall be given and a reasonable time to
correct the same on the part of Lessee shall be granted not to exceed 30 days
unless correction cannot reasonably be made within such period of time.

          40.  SECURITY MEASURES. Lessee hereby acknowledges that the rental
payable to Lessor hereunder does not include the cost of guard service or other
security measures, and that Lessor shall have no obligation whatsoever to
provide same.  Lessee assumes all responsibility for the overall protection of
Lessee, its agents, and invitees from acts of third parties.

          41.  EASEMENTS. Lessor reserves to itself the right, from time to
time, to grant such easements, rights and dedications that Lessor deems
necessary or desirable, and to cause the recordation of Parcel Maps and
restrictions, so long as such easements, rights, dedications, maps and
restrictions do not in any way affect Lessee's access to the Premises, or
unreasonably interfere or otherwise adversely affect Lessee's use of and
enjoyment of the Premises.  Provided such easements, rights, dedications, maps
and restrictions comply with the foregoing, Lessee shall sign any of the

                                     - 26 -
<PAGE>
 
aforementioned documents upon request of Lessor.

          42.  PERFORMANCE UNDER PROTEST. If at any time a dispute shall arise
as to any amount or sum of money to be paid by one party to the other under the
provisions hereof, the party against whom the obligation to pay the money is
asserted shall have the right to make payment "under protest" and such payment
shall not be regarded as a voluntary payment, and there shall survive the right
on the part of said party to institute suit for recovery of such sum. If it
shall be adjudged that there was no legal obligation on the part of said party
to pay such sum or any part thereof said party shall be entitled to recover such
sum or part thereof, as it was not legally required to pay under the provisions
of this Lease, together with such party's attorneys' fees and court costs to be
fixed by the Court.

          43.  AUTHORITY. If Lessee is a corporation, trust, or a general or
limited partnership, each individual executing this Lease on behalf of such
entity represents and warrants that he or she is duly authorized to execute and
deliver this Lease on behalf of said entity. If Lessee is a corporation, trust,
or partnership, Lessee shall, within thirty (30) days after execution of this
Lease, deliver to Lessor evidence of such authority satisfactory to Lessor.

          44.  INSURING PARTY. The Insuring Party under this Lease shall be the
Lessor. Lessee shall be responsible to insure its own property, and the contents
of the Premises to the extent Lessee desires to insure same and to carry such
liability insurance as Lessee may determine is appropriate, and as subject only
to the requirements of Paragraph 8 above.

determined by multiplying the square footage of Building E times the minimum net
rental per square foot of Building D for that year.

          (iii) Commencing January 1, 1999, and on each anniversary date
thereafter, the minimum net rental the Tenant shall pay for the next succeeding
year shall be the minimum net rental for the previous year plus the CPI

previous year times the percentage increase in the Consumer Price Index
Northeast Region for that year.   Providing, however, in no one year shall the
increase be greater than seven (7%) percent or less than two and one-half (2.5%)
percent.

     (f) Pending determination of the additional amounts to be paid by the
Tenant as a result of a Consumer Price  Index adjustment, the Tenant shall
continue to pay the minimum annual rental due Landlord as of the last adjustment
date or in the case of the first year, the amounts stipulated in this Lease and
when the additional amount has been determined, the Tenant, on the first day of
the month immediately following the furnishing by Landlord to Tenant of the
computation thereof shall pay to the Landlord the increased amount from the
commencement of the Lease Year in question up to and including the first day of
such month.

5.   SECURITY DEPOSITS:  INTENTIONALLY OMITTED
     ------------------  ---------------------

6.  UTILITIES:  Tenant shall, at its own cost and expense pay all charges when
    ---------                                                                 
due for water, gas, electricity, heat, sewer and water rentals or charges and
any other utility charges incurred in the use of the Demised Premises except as
or otherwise provided in this Lease.

7.   USE OF PREMISES: Tenant agrees to use the Leased Premises for
     ---------------                                              
pharmaceutical related businesses.   Any other unrelated use is prohibited
without the written approval of the Landlord which approval shall not be
unreasonably withheld.

8.  CONDITION OF PREMISES, ORDINANCES AND VIOLATIONS:
    ------------------------------------------------ 

     (a) The Tenant shall make no alteration,  addition or improvement in the
premises in excess of $25,000 without the prior
 
                                      -4-
<PAGE>
 
written consent of Landlord and in any event only be contractors or mechanics
approved by Landlord, which consent or approval shall not be unreasonably
withheld or delayed;

     (b) Throughout the term of this Lease, Landlord agrees to make structural
repairs to the premises which shall be deemed to mean repairs to the structural
frame, exterior of the premises, to the roof and to utilities and facilities
servicing the premises to the extent that they are located outside of the Leased
Premises, as well as to the common areas of the Landlord's premises, except as
previously noted, all at Landlord's expense unless such repairs are necessitated
by the act of Tenant or any of it's employees or business invites.  All other
non-structural repairs shall be done by the Tenant at Tenant's expense.  All
repairs and replacements shall be at least equal in quality of workmanship and
materials to that existing in Leased Premises at the commencement of this Lease.
Tenant shall indemnify the Landlord against all costs, expenses, liabilities,
losses, damages, suits, fines, penalties, claims and demands, including
reasonable attorney's fees, because of Tenant's failure to comply with the
foregoing covenant.  The Landlord shall in no event be required to make any
repair,  alteration or improvement to the Leased Premises except as set forth
above.  If, upon notice from Tenant, Landlord fails to make any such required
repairs, which affect the habitability of any portion of the demised premises,
Tenant may but shall not be required to make those repairs and deduct the cost
of same from future installments of rent.

     (c) The  necessity  for  and  adequacy  of  repairs  and replacements to
the Leased Premises shall be measured by the standard  which  is  appropriate
for  improvements  of  similar construction and class, provided that Tenant
shall in any event make all repairs necessary to comply with the building,
health and fire codes of Danbury, Connecticut.  Tenant shall not be obligated to
make any repairs or replacements which are structural in nature and are outside
the Leased Premises and generally serve the entire building.

     (d) Upon the last day or sooner termination of the term hereof, Tenant
shall surrender to Landlord the Demised Premises in broom  clean  condition.
All  alterations,   additions  and improvements, whether temporary or permanent
in character, which may be made upon the premises, either by the Landlord or the
Tenant, shall be surrendered with the premises as a part thereof upon the
termination of this Lease without compensation to the Tenant.  Tenant may
remove its trade fixtures provided however it shall restore the premises to
substantially the same conditions as existed prior to their installation.

     (e) Subject to Landlord's obligations set forth in subpara-
 
                                      -5-
 
<PAGE>
 
graph (b) above, Tenant shall:   Suffer no waste or injury to Demised Premises;
give prompt notice to the Landlord of any damage that may occur; execute and
comply with all laws, rules, orders, ordinances and regulations at any time
issued or in force, applicable to the Demised Premises or to the Tenant's use
and occupancy thereof, of the City, State and Federal Governments and Landlord,
and of each and every department, bureau and official thereof, and of the Board
of Fire Underwriters having jurisdiction thereof.  An adequate fire protection
system will be installed on the premises and during the term of this lease,
Tenant agrees to maintain a  service or maintenance agreement on said system
consistent with the manufacturer's recommendation or to pay its prorata share of
a master maintenance agreement if applicable.

9.  ASSIGNMENT: The Tenant shall not assign, mortgage or encumber this Lease in
    ----------                                                                 
whole or in part, or subject all or any part of the Leased premises to a sub-
lease without the prior written consent of the Landlord which consent shall not
be unreasonably withheld and in the event of a sale or merger of Tenant's
business to a entity of financial ability similar in all respects to Tenants as
of the commencement of this Lease, Landlord shall be notified but its consent
shall not be required.  The consent by Landlord to any assignment or subletting
shall not constitute a waiver of the necessity  for such consent to any
subsequent  assignment or subletting. This prohibition against assigning or
subletting shall be construed to  include a prohibition against  assigning or
subletting by operation of law.  If this Lease be assigned or if the Leased
premises or any part thereof be occupied by anybody other than the Tenant,
Landlord may collect rent from the assignee, or occupant and apply the net
amount collected to the rent herein reserved,  but no such assignment,
underletting,  occupancy or collection shall be deemed a waiver of this
provision or the acceptance of the assignee, under Tenant or occupant as lessee,
or as a release of Tenant from the further performance by it of the provisions
on its part to be observed or performed herein. Notwithstanding any assignment
or sub-lease, Tenant shall remain fully liable and shall not be released from
performing any of the terms of this Lease except where the assignment is a
result of a sale or merger of Tenant's business.

10.  FIRE AND OTHER CASUALTY:  If during the term of this Lease any of the
     -----------------------                                              
buildings comprising the Demised Property shall be partially or totally
destroyed by fire or other casualty or peril then the following shall be
applicable:

     (a) If, in Landlord's reasonable opinion (to be given to Tenant not later
than ten (10) days after notice to Landlord by Tenant of the happening of such
damage or destruction), the building or buildings cannot be repaired or restored
within a period of one hundred eighty (180) days from the date of such opinion,
then either Landlord or Tenant may, within ten (10) days
<PAGE>
 
next succeeding the giving of such opinion by Landlord, terminate this Lease by
giving notice to the other of such termination.  In that event, this Lease shall
terminate as to that building or buildings but shall remain in effect as to the
remaining building or buildings (unless the only other remaining building is
Building A in which event Tenant may terminate this Lease) and the rent and all
other payments for which Tenant may be liable under the terms of this Lease
shall be prorated and paid in full to the date of such destruction or damage.
If neither Landlord nor Tenant so terminate this Lease, then Landlord shall
repair or restore the building or buildings with reasonable diligence and the
rent shall abate on each damaged building from the date of the happening of such
damage or destruction until that building has been repaired or restored to the
extent reasonably necessary to enable Tenant to again use and occupy the
building, and Landlord shall repair or restore the building with reasonable
diligence.  Provided Landlord is proceeding with reasonable diligence to repair
or restore the building, Landlord shall not be responsible for any delays beyond
the reasonable control of Landlord which prevent such repair or restoration from
being completed within such one hundred eighty (180) day period.

      (b) If, in Landlord's reasonable opinion (to be given to Tenant not later
than ten (10) days after notice to Landlord by Tenant of the happening of such
damage or destruction),  the building or buildings can be repaired or restored
as set forth is subparagraph (b) above within one hundred eighty (180) days from
the date of such opinion, and the damage or destruction is such that a building
is capable of being partially used by Tenant, then, until such damage has been
repaired or restored, the rent shall abate in the proportion which that part of
the building which is rendered unfit for occupancy bears to the whole of the
building, and Landlord shall repair or restore the building with reasonable
diligence.   Providing Landlord is proceeding with reasonable diligence to
repair or restore the building, Landlord shall not be responsible for any delays
beyond the reasonable control of Landlord which prevent such repair or
restoration from being completed without such one hundred eighty (180) day
period.

     (c) Landlord and Tenant shall fully cooperate with each other regarding the
settlement and adjustment of insurance claims.  If Landlord is to repair or
restore any building, Tenant, at Tenant's sole cost and expense, shall remove
any machinery, equipment, furniture, inventory, or other items of personal
property from that building as shall be required by Landlord in order to repair
or restore the Improvements constituting a part of the building.

Also, Landlord shall have the free and uninterrupted right to possession of the
building to repair and restore the Improvements constituting a part of the
building, and such right shall extend to Landlord's employees, contractors,
subcontractors, laborers and suppliers.
 
                                      -7-
<PAGE>
 
      (d) Notwithstanding anything to the contrary contained herein, Landlord
shall not be obligated to repair or restore any damage to or destruction of the
Demised Property if the costs of repair or restoration, in Landlord's reasonable
opinion, exceeds the amount of insurance proceeds payable to Landlord by reason
of such damage or destruction.  In that event, Tenant shall have the option of
either (1) terminating this Lease as it applies to such damaged or destroyed
building or buildings or (2) requiring Landlord to repair or restore the damaged
property in which event Tenant shall assume responsibility for the payment of
all costs and expenses to repair or restore in excess of the insurance proceeds
due Landlord.  In the event Tenant elects the latter option and requires
Landlord to repair or restore it shall give written notice to Landlord of that
election within sixty (60) days of the damage or destruction and
contemporaneously with the giving of notice provide Landlord with adequate
security for the payment (based on written estimates) of all excess costs and
expenses. The excess costs incurred by Tenant shall be divided by the years
remaining in the Lease term and the annual rental due in each of the remaining
years shall be reduced by the resulting figure.  Anything herein  to  the
contrary  notwithstanding,  Landlord  shall  not  be responsible for repairing
or restoring any alterations, additions or improvements made to the Demised
Property by Tenant.  Furthermore, in no event shall Landlord be liable for any
loss of or damage to any of Tenant's property.

      (e) In the event that the partial destruction or casualty to the entire
Demised Premises is more than fifty percent (50%), the Landlord in its sole
discretion shall determine whether or not to repair the Demised Premises.  In
the event that the Landlord decides not to repair the Demised Premises, then and
in that event, this Lease shall cease and be terminated provided however should
such destruction or casualty occur in the final Lease year, Tenant may terminate
this Lease as it applies to the building or buildings so impacted upon notice to
Landlord.

11.  INDEMNITY AND INSURANCE:  From and after the commencement of this Lease,
     -----------------------                                                 
Tenant will indemnify and hold landlord harmless absolutely from and against any
and all claims,  suits,  actions,  damages,  costs, expenses or judgement, by
reason of any actual or claimed injury to person and/or property or loss of life
sustained in the Demised Premises during the term hereof except for such injury,
property damage or loss of life caused by negligence by Landlord, its employees
or agents.  If Landlord is made party to any litigation instituted against
Tenant, to which the foregoing indemnity may relate, Tenant will pay all
expenses, costs, damages, judgement and reasonable fees for counsel incurred 
by or imposed on Landlord in connection therewith or as a result thereof.

      Without limiting the foregoing and other indemnification provisions herein
contained, Tenant agrees, at Tenant's sole cost and expense, throughout the term
of this Lease, but for the mutual benefit of Landlord and Tenant, to maintain
general public liability insurance against claims for bodily injury or death, or
injury to property, occurring upon or in the Demised Premises, such insurance to
afford protection to the limit of not less than Two Million and 00/100
($2,000,000.00) Dollars in respect of any one accident, and not less than Two
Hundred Thousand and 00/100 ($200,000.00) Dollars in respect to property damage.

     All insurance provided for in this paragraph shall name Landlord as owner
and the Landlord's mortgagee as additional   
 
                                      -8-
<PAGE>
 
insureds as well as Tenant as insured, as their respective interests may appear,
and shall be effected under valid and enforceable policies issued by insurers
licensed to do business in the State of Connecticut. Tenant may carry the
insurance required under this paragraph under a blanket policy. Upon the
commencement of the term of this Lease and thereafter prior to the expiration
dates of the expiring policies thereto-fore furnished pursuant to this
paragraph, original certificates thereof issued by the respective insurers shall
be delivered by Tenant to Landlord. Tenant agrees to pay the cost of any such
insurance and to furnish Landlord, if requested, with evidence satisfactory to
Landlord of such payment. All such policies shall, to the extent obtainable,
contain an agreement by the insurers that such policies shall not be canceled
without at least forty-five (45) days prior written notice to Landlord.

      Tenant agrees that if it shall at any time fail to take out, pay for,
maintain or deliver any of the insurance policies as provided for in this
paragraph, or to make any other payment or perform any other act on the part of
Tenant to be made or performed, then Landlord may, but shall not be obligated to
do so, and on not less than fifteen (15) days notice to or demand upon Tenant
(and unless Tenant shall comply with such 15-day period) and without waiving or
releasing Tenant from any obligations of Tenant in this Lease contained, (i)
take out, pay for, maintain or deliver any of the insurance policies provided
for in this paragraph, or

          (ii) make any other payment or perform any other act on Tenant's part
to be made or performed as in this Lease provided. All sums so paid by Landlord
and all necessary incidental costs and expenses in connection with the
performance of any such act by Landlord, together with interest thereon at the
rate of twelve (12%) percent per annum from the date of the making of such
expenditure by Landlord, at the option of Landlord, shall be payable to Landlord
on demand or shall be added to any rent then due or thereafter becoming due
under this Lease, and Tenant agrees to pay any such sum or sums with interest as
aforesaid. All sums which may become payable to Landlord by Tenant, as in this
paragraph provided, and all sums payable by Tenant pursuant to any other
provision of this Lease, shall be deemed obligations of Tenant hereunder and
Landlord shall have (in addition to any other right or remedy) the same rights
and remedies in the event of nonpayment of any such sums by Tenant as in the
case of default by Tenant in the payment of rent. The notice provided for herein
shall not in any way affect the other notice provisions of this Lease.

      Each party agrees to use diligent efforts to include in each of its
policies insuring against loss, damage or destruction by fire or other insured
casualty a waiver of the insurer's right of





                                      -9-
<PAGE>
 
subrogation against the other party or, should such waiver be unobtainable (i)
an express agreement that such policy shall not be invalidated if the insured
waives or has waived before the casualty the right of recover against any party
responsible for a covered casualty or (ii) any other form of permission for the
release of such responsible party.  If such waiver, agreement or permission
shall not be, or shall cease to be, obtainable without additional charge or at
all, the insured party shall so notify the other party promptly after notice
thereof.  If the other party shall agree in writing to pay the insurer's
additional charge therefor,  such waiver, agreement or permission shall (if
obtainable) be included in the policy.

      As long as Landlord's fire insurance policies include the waiver of
subrogation or agreement or permission to release liability referred to in the
previous paragraph,  and the coverage is in amounts sufficient to cover any
claim being made then, Landlord waives, for itself and those claiming through or
under it, any right of recovery against Tenant, any other permitted occupant or
subtenant of the Premises and any of their employees, agents or contractors with
respect to that claim, occasioned by fire or other insured casualty.  If at any
time any of Landlord's policies shall not include such or similar provisions,
the waiver set forth in the foregoing sentence shall be of no further force or
effect.

     As long as Tenant's fire insurance policies include the waiver of
subrogation or agreement or permission to release liability previously referred
to, Tenant waives for itself and those claiming through or under it, any right
of recovery against any of their employees, agents or contractors, for any loss
occasioned by fire or other insured casualty.  If at any time any of Tenant's
policies shall not include such or similar provisions, the waiver set forth in
the foregoing sentence shall upon (20) days notice given by Tenant to Landlord,
be of no further force or effect from and after the giving of such notice.

12.  PROPERTY LOSS OR DAMAGE:  Landlord or its agents shall not be liable for
     -----------------------                                                 
any damage to property of Tenant, its employees or of others entrusted to Tenant
except damage caused by the negligence of Landlord, its employees or agents nor
the loss or damage to any property of Tenant by theft or otherwise. Furthermore,
the Landlord or its agents shall not be liable for any injury or damage to
persons or property resulting from fire, explosion, falling plaster, steam, gas,
electricity, water, rain or snow, or leaks from any part of the building housing
the Demised Premises or from the pipes, appliances or plumbing works or from the
roof, street or sub-surface or from any other place or by dampness or by any
other cause of whatsoever nature, unless caused by or due to the negligence of
Landlord, its agents, servants or employees.

                                     -10-
<PAGE>
 
      Landlord or its agents shall not be liable for any such damages caused by
other Tenants or persons in said building or caused by operations in
construction of any private, public or quasi-public work. Tenant shall give
immediate notice to Landlord in case of fire or accidents in the Demised
Premises or in the building, or of defects therein or in any building fixtures
or equipment. If Tenant shall move any safe, machinery, equipment, freight bulky
matter or fixtures which require special handling, Tenant agrees to employ only
persons holding a license to do said work and all work in connection therewith
shall comply with any regulations, law or ordinance affecting such work. Tenant
shall indemnify Landlord for, and hold Landlord harmless and free from damages
sustained by person or property for any damages or monies paid out by Landlord
in settlement of any claims or judgements related to the preceding as well as
for all expenses and reasonable attorney fees incurred in connection therewith
and all cost incurred in repairing any damage to the building or appurtenances.

13.  ACCESS:   Upon notice to Tenant,  and without causing an unreasonable
     ------                                                               
intrusion, the Landlord, its servants and agents, including representatives of
the insurance company or companies carrying insurance on the building containing
the Demised Premises, shall have the right to enter upon the said premises at
any time for inspection of the premises or for repairs to building or equipment
or without notice in an emergency or to take preventative measures to protect
and preserve the property of the Landlord.

     Upon notice to Tenant, and without causing an unreasonable intrusion,
Landlord shall have the right to enter the premises during business hours for
purposes of showing the premises to any prospective mortgagee or purchaser of
the premises or during the last twelve (12) months of the Lease for purposes of
reletting the premises.

14.  CONDEMNATION:  In the event of a condemnation of the premises, which shall
     ------------                                                              
include a taking of all or a substantial part of the building on the premises,
this Lease shall, at the option of either party, terminate upon the completion
of such taking. The rent shall be apportioned as of that date. The condemnation
award shall belong solely to the Landlord. Tenant shall be entitled to
relocation costs, if any, provided said costs may be separately determined as an
element of the award and not included in the determination of the value of the
interest of the Landlord in the Leased Premises. In the event of a partial
taking of the premises in such manner that the Tenant is able to continue
without substantial modifications, the operation then being conducted on the
Demises Premises, then this Lease shall remain in full force and effect and the
Landlord and Tenant shall agree upon an equitable rent adjustment reflecting
such partial taking. Any




                                     -11-
<PAGE>
 
award for partial taking shall belong solely to the Landlord. Nothing herein
shall be construed to deprive Tenant of its rights upon condemnation as set
forth in the Connecticut General Statutes.

15.  SUBORDINATION:  This Lease is subject and subordinate to all mortgages
     -------------                                                         
which may now or hereafter affect such Leases or the real property of which the
Demised Premises form a part, and to all renewals, modifications,
consolidations, replacements and extensions thereof. This clause shall be self-
operative and no further instrument of subordination shall be required by any
mortgage. In confirmation of such subordination, Tenant shall execute promptly
any certificate that Landlord may request. Tenant hereby constitutes and
appoints Landlord as the Tenant's attorney-in-fact to execute any such
certificate or certificates for and on behalf of the Landlord. Landlord,
however, covenants and agrees that it will obtain from all future mortgagees
holding a mortgage on the premises written assurance that so long as the Tenant
is not in default under the terms and conditions of this Lease, Tenant's use,
occupation and possession of the premises and all rights of Tenant under this
Lease shall not be affected or disturbed by the bringing of any action to
foreclose or otherwise enforce any such mortgage.

16.  ESTOPPEL CERTIFICATES:   The Landlord and the Tenant shall, without charge,
     ---------------------                                                      
at any time, and from time to time, as the same shall be reasonably requested,
within ten (10) days after a written request by the other, certify by a written
instrument to the other, or any person, firm or corporation specified by the
other:

      (a) That there is no default under this Lease, that this Lease is
unmodified and in full force and effect, or if there have been any
modifications, that the same is in full force and effect as modified and stating
the modifications.

     (b) Whether or not there are then existing any setoffs or defenses against
the enforcement of any of the agreements, terms, covenants, or conditions
contained herein and any modifications hereof upon the part of the Tenant to be
performed or complied with, and if so, specifying the same.

     (c) The date, if any, to which the rent and other charges hereunder have
been paid.

     (d) That prior to the date of the issuance of the certificate required
hereby, to the best of the knowledge of the signer thereof,  there has been no
violation or breach which would constitute a default under this Lease.

17.  DEFAULT:
     ------- 

      (a) The occurrence of any of the following shall constitute an event of
default:




                                     -12-
<PAGE>
 
          (i)   Delinquency in the payment of any rent including supplemental
or additional rent payable under this Lease continuing for a period of ten (10)
days after notice.

          (ii)   Delinquency by the Tenant in the performance of or compliance
with any of the conditions contained in this Lease other than those referred to
in the foregoing subparagraph (1), for a period of thirty (30) days after
written notice thereof from the Landlord to the Tenant, except for any default
not susceptible of being cured within such thirty (30) day period, in which
event the time permitted to the Tenant to cure such default shall be extended
for as long as shall be necessary to cure such default, provided the Tenant
commences promptly and proceeds diligently to cure such default, and provided
further that such period of time shall not be so extended as to jeopardize the
interest of the Landlord in this Lease or so as to subject the Landlord or the
Tenant to any civil or criminal liabilities.

          (iii)  Filing by the Tenant in any court pursuant to any statute,
either of the United States or any state, of a petition in bankruptcy or
insolvency, or for reorganization, or for the appointment of a receiver or
trustee of all or a portion of the Tenant's property, or an assignment by the
Tenant for the benefit of creditors.

           (iv)  Filing against the Tenant in any court pursuant to any statute,
either of the United States or of any state, of a petition in bankruptcy or
insolvency, or for reorganization or for appointment of a receiver or trustee of
all or a portion of the Tenant's property, if within ninety (90) days after the
commencement of any such proceeding against the Tenant such petition shall not
have been dismissed.

      (b) Upon the occurrence of an event of default, the Landlord at any time
may give written notice to the Tenant specifying such event of default and
stating that this Lease shall expire on the date specified in such notice, which
shall be at least thirty (30) days after the giving of such notice, and upon the
date specified in such notice this Lease and all rights of the Tenant hereunder
shall terminate.

      (c) Upon the expiration of this Lease pursuant to subparagraph 17 (b)
above, the Tenant shall peacefully surrender the Leased property to the Landlord
and the Landlord, upon or at any time after any such expiration, may without
further notice reenter the Leased property and repossess it by summary
proceedings, ejectment, or otherwise, and may dispossess the Tenant and remove
the Tenant and all other persons and property from the Leased property and may
have, hold and enjoy the Leased property and the right to receive all rental
income therefrom.
<PAGE>
 
      (d) At any time after such expiration, the Landlord may relet the Leased
property or any part thereof for such term and on such conditions as the
Landlord, in its uncontrolled discretion, may determination and may collect and
receive the rent therefor.  The Landlord shall in no way be responsible or
liable for any failure to relet the Leased property or any part thereof, or for
any failure to collect any rent due upon any such reletting.

      (e) No such expiration of this Lease shall relieve the Tenant of its
liability and obligations under this Lease, and such liability and obligations
shall survive any such expiration. In the event of any such expiration, whether
or not the Leased property or any part thereof shall have been relet, the Tenant
shall pay to the Landlord the rent and supplemental and additional rent required
to be paid by the Tenant up to the time of such expiration, and thereafter the
Tenant, until the end of what would have been the term of this Lease in the
absence of such expiration, shall be liable to the Landlord for, and shall pay
to the Landlord, as and for liquidated and agreed current damages for the
Tenant's default;

          (i) the equivalent of the amount of the rent and additional rent which
would be payable under this Lease by the Tenant if this Lease were still in
effect, less

          (ii) the net proceeds of any reletting effected pursuant to the
provisions of subparagraph 17(d) above, after deducting all the  Landlord's
expenses  in  connection  with  such  reletting, including, without limitation,
all repossession costs, brokerage commissions, legal expenses, reasonable
attorney's fees, alteration costs and expenses of preparation for such
reletting.

      (f) The Tenant shall pay such current damages, called deficiency, to the
Landlord monthly on the days on which the rent, supplemental, and additional
rent would have been payable under this Lease if this Lease were still in
effect, and the Landlord shall be entitled to recover from the Tenant each
monthly deficiency as such deficiency shall arise. At any time after such
expiration, whether or not the Landlord shall have collected any monthly
deficiency, the Landlord shall be entitled to recover from the Tenant, and the
Tenant shall pay to the Landlord, on demand, as and for liquidated and agreed
final damages for the Tenant's default, an amount equal to the difference
between the rent and supplemental and additional rent reserved hereunder for the
unexpired portion of the Lease term and the then fair and reasonable rental
value of the Leased property for the same period. If the Lease property or any
part thereof is relet by the Landlord for the unexpired term of this Lease, or
any part thereof, before presentation of proof of such liquidated damages to any
court, commission, or tribunal, the amount of rent reserved upon such




                                     -14-
<PAGE>
 
reletting shall be deemed prima facie to be the fair and reasonable rental value
for the part or the whole of the Leased property so relet during the term of the
reletting.  Nothing herein contained shall limit or prejudice the right of the
Landlord to prove for and obtain as liquidated damages by reason of such
termination an amount equal to the maximum allowed by any statute or rule of law
in effect at the time when, and governing the proceedings in which, such damages
are to be proved.

      (g) The Tenant hereby expressly waives, so far as permitted by law, the
service of any notice of intention to reenter provided for in any statute, or of
the institution of legal proceedings to that end.  The Tenant, for and on behalf
of itself and all persons claiming through or under the Tenant, also waives any
right of redemption or reentry or repossession or to restore the operation of
this Lease in case the Tenant shall be dispossessed by a judgement or by warrant
of any court or judge or in case of reentry or repossession by the Landlord.  In
case of any expiration of this Lease, the Landlord and the Tenant, so far as
permitted by law, waive trial by jury in any action, proceeding, or counterclaim
brought by either of the parties hereto against the other on any matter arising
out of or in any way connected with this Lease, the relationship of Landlord and
Tenant, the Tenant's use or occupancy of the Leased property, or any claim or
injury or damage.  The terms "enter", "reenter", "entry", or "reentry", as used
in this Lease are not restricted to their technical legal meaning.

18.  COSTS AFTER DEFAULT:  The Tenant shall pay and indemnify the Landlord
     -------------------                                                  
against all legal costs and charges, including counsel fees lawfully and
reasonably incurred, in obtaining possession of the Demised Premises after a
default of the Tenant or after the Tenant's default in surrendering possession
upon the expiration of earlier termination of the term of the Lease or enforcing
any covenant of the Tenant herein contained.  In any action between the parties
under this Lease the prevailing party shall be entitled to recover its
reasonable attorney's fees.

19.   SIGNS:  The Tenant may place and maintain a sign on said Demised Premises
      -----

Landlord, which approval shall not be unreasonably withheld, and shall be

request from the Tenant Waivers of Lien in the event Tenant shall commence to do
interior repairs to said premises. In the event the Landlord requests such
Waivers of Lien, he shall supply the same to the Tenant and the Tenant shall
have the same executed by all suppliers of material and labor to said Demised
Premises prior to the commencement of said work.

28.  ADDITIONAL RENT - OTHER IMPOSITIONS:  Tenant shall bear and pay as
     -----------------------------------                               
additional rent its proportionate share (unless usage is metered or charged
directly to the Demised Premises in which event Tenants will pay such charges
directly) as hereinafter set forth, of all charges for water supplied to the
Entire Premises, including sewer rents, any expenses of any municipal
assessments that may be levied on the land and buildings to the extent that such
assessments are and become due and payable in full or in installments during the
term and any extension of this Lease. The proportionate share to be paid by the
Tenant shall be computed on the basis of the total rentable floor area of the
Demised Premises as it bears to the total rentable floor area of the Entire
Premises. Upon receipt of each bill for such taxes, assessments, or charges,
Landlord shall notify Tenant of the portion thereof payable by Tenant and
enclose a copy of the bill and computation and Tenant shall within fifteen (15)
days thereafter pay such portion to Landlord. The Landlord and Tenant agree that
Tenant's proportionate share of the buildings shall be sixty-five (65%) percent.
Said figure is based upon Tenant's rentable floor area of 87,680 square feet,
and the total rentable floor area in the Entire Premises of 135,000 square feet.

      (a) Additional Rent - Common Area:  Tenant agrees that it will pay to the
          -----------------------------                                        
Landlord as and when bills are rendered therefore, the allocated share taking
into account any costs and maintenance assumed directly by Tenant for area
reserved to its exclusive use of all operating costs excluding mortgage interest
and amortization payments for maintenance of the Common Facilities as herein
defined, including but not limited to the following costs incurred: parking lot
and common area lighting including the replacement of non-functioning or
malfunctioning bulbs; common area and parking lot cleaning and general
maintenance and landscaping; garbage removal; snow and ice removal; premiums on
liability insurance policies for any common area in parking lot; policing and
maintaining of the parking area, walks and ways and for areas common to all
Tenants of the buildings as may be necessary from time to time including
restriping the paved area. Tenant shall contract, maintain, and pay for its own
garbage removal if required by Landlord. Any extraordinary costs or expense
attributable to Tenant's use shall be the sole responsibility of Tenant.

     (b) Additional Rent - Real Estate Taxes:  Tenant agrees to
         -----------------------------------                   




                                     -17-
<PAGE>
 
pay as additional rent its proportionate share, as hereinafter set forth, of all
real estate taxes assessed against the land and buildings.  The proportionate
share of the cost to be paid by the Tenant shall be computed on the basis of the
total rentable floor area of the Demised Premises as it bears to the total
rentable floor area of the Entire Premises.  The Landlord and Tenant agree that
Tenant's proportionate share of the buildings shall be sixty-five (65%) percent.
Said figure is based upon Tenant's rentable floor area of 87,680 square feet,
and the total rentable floor area in the Entire Premises of 135,000 square feet.
Real estate taxes for the buildings will be determined from the assessment of
the land and buildings times the established mill rate.  In the event real
estate taxes are assessed separately against any of the demised buildings during
the term of the Lease, the Landlord and Tenant agree the Tenant shall pay its
proportionate share as hereinbefore set forth of the taxes attributable to the
land and shall pay all of the taxes attributable to each separately assessed
Demised Building.

      (c) Additional Rent Insurance:  Tenant agrees it will pay to the Landlord,
          -------------------------                                             
its proportionate share of the costs of all hazard, fire,  liability and rental
value insurance incurred for the buildings in which the Demised Premises are
located and also for the Entire Premises.  Said insurance shall be for the
minimum of the fair replacement value of said buildings and public liability
insurance in an amount not less than two million and shall be in the form of an
extended coverage policy.  The proportionate share of the costs to be paid by
Tenant shall be computed on the basis of the total floor area of the Demised
Premises as it bears to the total floor area of the buildings, and the same
shall be deemed additional rent under this Lease.  The Landlord and Tenant agree
that Tenant's proportionate share of the buildings shall be sixty-five (65%)
percent.  Said figure is based upon Tenant's rentable floor area of 87,680
square feet which amount may be changed after verification and certification by
Landlord, and the total rentable floor area in Entire Premises of 135,000 square
feet.  Notwithstanding the above, in the event the rating of said buildings is
increased because of the use of said buildings by a particular tenant, then in
such event that increase in the insurance premium shall be attributable to the
Tenant.

     (d) Payment of Additional Rent:  Notwithstanding any other paragraph to the
         --------------------------                                             
contrary, Tenant shall pay its additional rent as determined by this paragraph
30 on a monthly basis, on the first day of each month, in addition to the
minimum guaranteed rental. This monthly payment to be determined prior to the
commencement date shall be an estimate based on a total annualized figure per
square foot divided into 12 equal payments.  On February 1st of each year during
the Lease term that additional rent is due, the Landlord will compute any over-
payment or under-payment of said





                                     -18-
<PAGE>
 
additional rent, and shall bill the Tenant within thirty (30) days or shall
credit the Tenant accordingly.

      (e)  Net Lease: All rent shall be absolutely net to Landlord, so that this
           ---------                                                            
Lease shall, except as hereinbefore provided to the contrary, yield net to the
Landlord the rent, to be paid in each year during the term of this  Lease and
any  renewal  term. Accordingly, the Tenant's proportionate share of all costs,
expenses and obligations of every kind or nature whatsoever, relating to the
Demised Premises or the Entire Premises, or any improvements thereon, which may
arise or become due during the term of this Lease shall be paid by the Tenant,
and the Landlord shall be indemnified and saved harmless by the Tenant from and
against same.  Nothing herein contained shall be deemed to require the Tenant to
pay or discharge any liens or mortgages of any character whatever which may
hereafter be placed upon the Demised Premises by the affirmative act of the
Landlord. The Landlord and Tenant agree that Tenant's proportionate share of the
buildings shall be sixty-five (65%) percent.

      (f) Landlord agrees to maintain complete records of all costs reimbursable
by Tenant under the terms of this Lease. All such records shall be maintained in
accordance with generally accepted accounting practices and shall be retained
for a period of four (4) years following the date on which such costs were
charged to Tenant.  Tenant shall have the right, through its representatives, to
examine,  at the Landlord's office,  such records  at  all reasonable times.

     (g) If Landlord and Tenant cannot reach agreement on all costs reimbursable
by Tenant under the Lease, then Landlord and Tenant agree the matter shall be
determined by arbitration.

          (i) Landlord and Tenant shall each appoint an arbitrator by written
notice given to the other party not later than twenty (20) days after Landlord
and Tenant have failed to agree.   If either Landlord or Tenant  shall have
failed to appoint an arbitrator within such period of time and, thereafter,
shall have failed to do so by written notice given within a period of ten (10)
days after notice by the other party requesting the appointment of such
arbitrator, then such arbitrator shall be appointed by the American Arbitration
Association or its successor (the branch office of which is located in or
closest to the Premises) upon request of the party who shall have timely
appointed an arbitrator.

          (ii) The two (2) arbitrators shall attempt to reach agreement on the
matter at issue.  In the event they are unable to reach  agreement  within
thirty  (30)  days  after  their  joint appointment, they shall appoint a third
(3rd) arbitrator (the "Referee") by written notice given to both Landlord and
Tenant, and, if they fail to do so by written notice given within thirty




                                     -19-
<PAGE>
 
(30) days after their appointment, the Referee shall be appointed by the
American Arbitration Association or its successor upon request of Landlord or
Tenant.

          (iii)  The Referee, selected as aforesaid, shall within thirty (30)
days after his appointment render his decision, which decision shall be strictly
limited to choosing one of the two determinations made by the two arbitrators
chosen by Landlord and Tenant with respect to the matter. The decision of such
arbitrators or the Referee, as the case may be, shall be binding upon Landlord
and Tenant. Duplicate original counterparts of such decision shall be sent
forthwith by the arbitrators or the Referee, as the case may be, by certified
mail, return receipt requested, to both Landlord and Tenant.

29.   SURRENDER OF PREMISES:   Notwithstanding anything to the contrary in this
      ---------------------                                                    
Lease on the last day of the term hereof, or on any sooner termination, Tenant
shall surrender the Premises to Landlord in the same condition as received,

occasioned by the installation or removal of its trade, fixtures, furnishings
and equipment.

30.  HOLDING OVER:  If Tenant, with Landlord's consent, remains in possession of
     ------------                                                               
the Premises or any part thereof after the expiration of the term hereof, such
occupancy shall be a tenancy from month to month upon all the provisions of this
Lease with fifty (50%) percent premium paid to Landlord, unless other
arrangements are made with Tenant  at Leased  sale option,  pertaining to the
obligations of Tenant.

31.  LATE CHARGE:  There shall be assessed against the Tenant at the Landlord's
     -----------                                                               
option in addition to the Landlord's other remedies named herein, a late charge
for rent not received by the Landlord by the end of fifteen (15) days after the
date it is due in the amount of five (5%) percent of the monthly payment.

32.  MAINTENANCE OF HVAC SYSTEM:  Tenant agrees to maintain during the term of
     --------------------------                                               
this Lease and any renewals or extensions thereof, a service or maintenance
agreement in connection with the HVAC system with a company acceptable to the
Landlord for at least a semiannual servicing of said equipment.

33.   QUIET ENJOYMENT:   The Landlord covenants to the Tenant, subject to the
      ---------------                                                        
conditions and covenants herein contained on paying the rent and performing the
covenants aforesaid, that the Tenant shall and may peaceably and quietly have,

     ----------------------                                                
extension thereof, elect to sell all or any portion of the leased premises,
whether separately or as a part of the larger parcel, known as 131 West Street,
Danbury, Connecticut, the Tenant shall have the right of first refusal to meet
any bona fide offer of sale on the same terms and conditions of such offer.
Upon the Tenant's failure to meet such bona fide offer within 30 days after
notice thereof from the Landlord, the Landlord shall be free to sell the
premises or portion thereof to such third person in accordance with the terms
and conditions of his offer.

38.  OPTION TO EXTEND: The Tenant shall have an option to extend
       -----------------                                          
this Lease on the entire 87,680 square feet of demised premises for an
additional ten (10) years.

     The minimum net rental per annum on the buildings designated B, C, D, and E

succeeding Lease years during the extended Lease term shall be adjusted annually
and shall be the minimum net rental for the previous Lease year times the

previous 12 months payable in monthly installments.  Providing, however, that in
any one year the increase shall not be greater than seven (7%) percent or less
than two and one-half (2.5%) percent.

modified by this paragraph, shall remain the same and in full force and effect

39.  LANDLORD LIABILITY:   It is expressly understood and agreed by Tenant that
     ------------------                                                        
none of Landlord's covenants, understandings or agreements are made or intended
as personal covenants, undertakings or agreements by Landlord, and any liability
for damage or breach of non-performance by Landlord shall be collectible only
out of Landlord's interest in the buildings and land and no personal liability
is assumed by, nor at any time may be asserted against Landlord or his heirs, or
legal representatives, all such liabilities, if any, being expressly waived and
released by Tenant. Provided, however, if Tenant obtains a final judgement
against Landlord based upon breach by Landlord of his covenants, warranties,
undertakings or agreements contained in this Lease, and if Landlord does not
satisfy such judgement within thirty (30) days after entry thereof, Tenant may,
successively if necessary (and in addition to all other rights and remedies
provided at law or in equity or elsewhere herein) set off the amount of such
judgement against the rent or any other amounts payable to Landlord by Tenant
hereunder next due under the provisions of this Lease. Anything herein to the
contrary notwithstanding, the waiver of Landlords personal liability set forth
in this Paragraph 39 shall not apply to any liabilities of Landlord arising
pursuant to Paragraph 35, Hazardous Waste, or for over-payment of any rent by
Tenant.

      It is further expressly understood and agreed by Tenant that Landlord
reserves the right, at any time during the Lease Term, to transfer title to the
demised premises free from any Right of First Refusal set forth in Paragraph 37
to a Limited Liability Company or other limited liability entity providing
Landlord retains a controlling interest in said company or entity.

                No expenses shall be included as both Expenses and Complex

Expenses;

                (iii)  Building and Complex start-up or opening expenses;

                (iv)   except as provided hereinbelow, expenditures for capital
improvements or other expenses which are capital in nature, as determined
pursuant to generally accepted accounting principles consistently applied except
for those de minimis amounts that are expensed;

                (v)    advertising, marketing and promotional expenditures;

                (vi)   legal fees and other professional fees for lease
negotiations and disputes with tenants;

                (vii)  as a deduction, amounts received by Landlord through
proceeds of insurance to the extent the proceeds are compensation for expenses
which were previously included as Expenses hereunder;

                (viii) the cost of repairs or replacements incurred, by reasons
of fire or other casualty, or caused by the exercise of the right of eminent
domain, or compensable to Landlord by virtue of Landlord's insurance;

                (ix)   expenses for painting, redecorating or other work which
Landlord, at its expense, performs for Tenant or for any other tenant in leased
areas of the Building or the Complex other than painting, redecorating or other
work which is standard for or periodically performed in the Building or the
Complex; and

                (x)    interest and amortization payments or other payments
(except escrows for items included in Expenses) on any mortgages and rental
under any ground or underlying leases.

                If Landlord and/or others shall purchase any item of capital
equipment or make any capital expenditures designed to result in savings or
reductions in Expenses or Complex Expenses, then the costs for same shall be
included in Expenses or Complex Expenses. The costs of capital equipment or
capital expenditures are to be included in Expenses or Complex Expenses for the
calendar year in which the costs are incurred and subsequent calendar years on a
straight line basis amortized over such period of time as reasonably can be
estimated as the time in which such savings or reductions in Expenses or Complex
Expenses are expected to equal Landlord's costs for such capital equipment or
capital expenditure with an interest factor equal to the Prime Rate at the time
of Landlord's having actually incurred said costs. If Landlord and/or others
shall lease any such item of capital equipment designed to result in savings or
reductions in Expenses, then the rentals and other costs paid pursuant to such
leasing shall be included in Expenses or Complex Expenses for the calendar year
in which they were incurred.

                If during all or part of any calendar year, including the
Initial Year, Landlord and/or others shall not furnish any particular item(s) of
work or service which would constitute an Expense or Complex Expense hereunder
to portions of the Building or the Complex due to the fact that construction of
the Building or the Complex is not completed, or such portions are not occupied
or leased, or because such item of work or service is not required or desired by
the tenant of such portion, or such tenant is itself obtaining and providing
such item of work or service, or for other reasons, for the purposes of
computing the Additional Rent payable hereunder the amount of the Expenses or
Complex Expenses for such item for such period shall be increased by an amount
equal to the

                                     - 7 -
<PAGE>
 
additional operating and maintenance expenses which would reasonably have been
incurred during such period by Landlord and/or others if it or they had at its
or their own expense furnished such item of work or service to such portion of
the Building or Complex; it being the intention of this provision that
Landlord's determination of any increase in Expenses not be biased by any
increase attributable solely to an increase in occupancy or the provision of new
services or the like.

                (b)  In the event (i) that the Commencement Date shall occur on
other than the first day of a calendar year, or (ii) that the Expiration Date or
other termination of this Lease shall be a day other than the last day of a
calendar year, or (iii) of any abatement of the Fixed Rent payable hereunder
pursuant to any provision of this Lease for any period of time not equal to a
full calendar year, or (iv) of any increase or decrease in the gross rentable
area of the Demised Premises or any increase in the gross rentable area of the
Building or the Complex, then in each such event in applying the provisions of
this Article 3 with respect to such calendar year in which such event shall have
occurred, appropriate adjustments shall be made to Tenant's Proportionate Share
of Expenses payable pursuant to Paragraph 3(c) so as to apportion such payment
on the basis of (i) the pro rata portion of the calendar year during which such
payment is to be made and/or (ii) the increase or decrease in Tenant's
Proportionate Share of Expenses by virtue of the changes in any such gross
rentable area.

                (c)  Tenant shall be responsible for Tenant's Proportionate
Share of any increase in Expenses paid or incurred by Landlord in each Lease
Year during the Term over the Expenses paid or incurred by Landlord during the
Initial Year, as hereinafter provided. Attached hereto as Exhibit H is a true
copy of the statement of Expenses for the Building for the calendar years 1991
and 1992.

                     (1)  During each Lease Year Tenant shall pay to Landlord
monthly, on the first day of each calendar month, as Additional Rent, Landlord's
good faith estimate of Tenant's Share of any increase in Expenses paid or
incurred by Landlord in each Lease Year over the Expenses paid or incurred by
Landlord during the Initial Year.

                     (2)  Prior to the end of the Initial Year and thereafter
for each successive Lease Year, or part thereof, Landlord shall send to Tenant a
statement of the projected increase in Expenses, ("Projected Expense Increase")
for the applicable Lease Year, if any, broken down by categories as set forth in
Exhibit H (an "Expense Projection") and shall indicate what the estimated amount
of Tenant's Proportionate Share of said increase in Expenses shall be, said
amount to be paid in equal monthly installments (rounded to the nearest whole
dollar) in advance on the first day of each month by Tenant as Additional Rent,
commencing January 1st of the applicable Lease Year.

                     (3)  If during the course of any Lease Year, Landlord shall
have reason to believe that the increase in Expenses shall be higher than that
upon which the aforesaid Expense Projection was originally based, as set forth
in subparagraph (c) (2) above, then Landlord shall be entitled to advise Tenant
of an adjustment in future monthly projection amounts to the end result that
Landlord's Projected Expense Increase shall be on a reasonably current basis
each Lease Year.

                     (4)  Within ninety (90) days following the end of each
Lease Year, Landlord shall send to Tenant a statement of the actual increase in
Expenses incurred for the prior Lease Year showing Tenant's Proportionate Share
of the increase in Expenses due from Tenant, which statement shall be certified
as being accurate by Landlord, and which shall show Expenses broken down by
categories as set forth in Exhibit H. In the event that the amount

                                     - 8 -
<PAGE>
 
prepaid by Tenant exceeds the amount that was actually due based upon actual
year end cost, then Landlord shall pay to Tenant an amount equal to the
overcharge.  In the event that Landlord has undercharged Tenant, then Landlord
shall provide Tenant with an invoice stating the additional amount due, which
amount shall be paid in full by Tenant within twenty (20) days of receipt.

                     (5)  Tenant shall have the right, for a period of four (4)
months following the receipt of each statement of the actual Expenses incurred
for the prior Lease Year, to audit the records of Landlord in support of such
statement at the offices of Landlord during regular business hours on a date and
at a time reasonably satisfactory to Landlord and upon at least fourteen (14)
days prior notice to Landlord. Upon the completion of such audit, Tenant shall
file any written objections to the statement with Landlord within said four (4)
month period. In response to the filing of any objections, the parties shall
confer and a final amount shall be agreed upon between the parties within thirty
(30) days thereafter. Upon such settlement, or in the event of the passage of
the period for review by Tenant, the determination shall be final and binding
upon the parties and no further adjustments shall be made with reference to such
Lease Year. If despite good faith efforts, the parties are unable to reach a
complete settlement of any objections filed by Tenant, the parties agree to
refer any unsettled objections to a mutually acceptable independent accountant
with experience in the real estate industry, whose determination shall be
binding on both parties. If the parties are unable to agree on a mutually
acceptable independent accountant, each party shall appoint an independent
accountant acceptable to it and the two independent accountants so appointed
shall appoint the independent accountant to whom the objections matter shall be
referred.

                (d)  Each and every of the aforesaid Expense Projection amounts
shall for all purposes be treated and considered as Additional Rent and the
failure of Tenant to pay the same as and when due in advance and without demand
shall have the same effect as a failure to pay any installment of the Fixed Rent
and shall afford Landlord all the remedies provided in this Lease therefor,
including, without limitation, the Late Charge as provided in Paragraph 2(c) of
this Lease.

                (e)  Tenant acknowledges and agrees that Landlord shall have the
right to change the period of the Lease Year (but may not change the period of
the Initial Year), either before or during the Term, to any other fiscal year or
twelve month period, provided that such change shall not result in any item of
Expenses being included twice in either the same or different Lease Years. In
the event that Landlord makes such a change, then the same shall be effective
upon written notice to Tenant and, in such event, Tenant shall pay Tenant's
Proportionate Share of any increase in Expenses paid or incurred by Landlord
over the Expenses paid or incurred by Landlord during the Initial Year for the
period from the end of the initially designated Lease Year, as last billed, to
the beginning of the newly designated Lease Year, prorated for such period,
within twenty (20) days of the rendering by Landlord of the bill for such
interim period. If the Building shall have been less than ninety-five percent
(95%) occupied during the Initial Year or any entire Lease Year, then the
Expenses shall be projected for the Initial Year and such Lease Year as set
forth in the last paragraph of Paragraph 3(a) of this Lease. Real Estate Taxes,
for the purposes of this Lease shall reflect the full assessed value of the
Building as a completed office building multiplied by the tax rate then in
effect. If all the Land, Building and other Improvements have not been included
in the assessed value of the Building for the calculation of Real Estate Taxes,
then the Real Estate Taxes shall be adjusted by Landlord to reflect the amount
of Real Estate Taxes which would be assessed against a fully completed Building,
i.e. those imposed on the Building if all of the Land, Building and

                                     - 9 -
<PAGE>
 
other Improvements were completed and included in the assessed value of the
Building.


          4.    Completion of Improvements and Commencement of Rent.
                --------------------------------------------------- 

                (a)  Landlord agrees to construct the Tenant Improvements (as
such term is defined in Exhibit B attached hereto and made part hereof) in
accordance with the terms, conditions and provisions set forth in Exhibit B.
Landlord shall proceed diligently to complete such work in the manner specified
herein.

                (b)  The Demised Premises shall be deemed ready for occupancy
and the Commencement Date hereunder shall occur on August 1, 1993 or such later
date that (i) the Demised Premises shall be delivered to Tenant in tenantable
condition, free of violations of any health, safety, fire and other statutes and
regulations governing the Demised Premises and its use, all of which shall be
established by issuance of a certificate (temporary or final) by appropriate
governmental authority, permitting occupancy of the Demised Premises for the
purposes set forth herein; and (ii) Landlord has substantially completed the
initial installations and other work in and to the Demised Premises agreed to be
performed by it pursuant to Paragraph 4(a) (and Landlord shall be deemed to have
substantially completed said installations and other work notwithstanding that
minor or insubstantial details of construction, mechanical adjustment or
decoration remain to be performed within the Demised Premises or any part
thereof, the non-completion of which does not materially interfere with Tenant's
use of the Demised Premises). If the occurrence of any of the conditions listed
in the preceding sentence, and thereby the making of the Demised Premises ready
for occupancy, shall be delayed due to a Tenant Delay (as defined in Section 3.2
of Exhibit B), then the Commencement Date shall be accelerated by a time period
equal to the number of days of Tenant Delay so caused by Tenant; provided,
however, that the Commencement Date shall not be accelerated to a date earlier
than August 1, 1993. In the event that any such Tenant Delay days shall be
asserted by Landlord, Landlord shall notify Tenant of the same as provided in
Section 3.2 of Exhibit B. If the Commencement Date does not occur by August 15,
1993 for any reason other than a Tenant Delay, Landlord shall allow Tenant a day
of free Fixed Rent for each day after August 15, 1993 (net of Tenant Delay days)
until the Commencement Date occurs (which free Fixed Rent shall be in addition
to that allowed under Paragraph 2 (d) hereof). If the Commencement Date does not
occur by December 15, 1993 for any reason other than a Tenant Delay, Tenant may
terminate this Lease by giving written notice of termination to Landlord prior
to the Commencement Date. In the event of such a termination, Landlord shall
refund the Security Deposit and any pre-paid rental to Tenant. If Landlord
obtains a temporary certificate of occupancy, Landlord (i) shall proceed
diligently to complete or correct such items as are necessary to obtain a final,
unconditional certificate of occupancy for the Demised Premises and (ii) shall
be responsible for all costs, fines or penalties imposed as a result of any
delays in completing work required under the temporary certificate of occupancy.

                (c)   Tenant may occupy the Demised Premises as soon as the same
are ready for its occupancy and the Commencement Date shall have occurred (but
not prior to said date except for installation of Tenant's personal property or
otherwise with the express consent of Landlord). If and when Tenant shall take
actual possession of the Demised Premises, it shall be conclusively presumed
that the same is in satisfactory condition, except as to (i) those items of work
remaining to be performed by Landlord pursuant to this Paragraph 4, (ii) latent
defects in the construction of the Tenant Improvements of which Tenant notifies
Landlord within one year after the Commencement Date, or (iii) any items of work
set forth on a "Punch List" to be submitted to and acknowledged by Landlord in
writing within thirty (30) days after the Commencement

                                     - 10 -
<PAGE>
 
Date.  Landlord shall proceed diligently to complete such Punch List items.

                (d)   Upon the occurrence of the Commencement Date, the parties
shall execute a letter agreement confirming the Commencement Date and the
Expiration Date and specifying the amount of Fixed Rent payable during the
initial month if the Commencement Date occurs on a day other than the first day
of the month.


           5.   Covenants  as  to  Condition  of  Premises  and Compliance with
                ---------------------------------------------------------------
                Laws.
                ---- 

                (a)  Subject to the waiver of subrogation provisions of
Paragraph 10(d) hereof, in the event that the Building or any of the equipment
affixed thereto or stored therein should be damaged as a result of any act of
Tenant, its agents, servants, employees, invitees or contractors, Tenant shall,
upon demand, pay to Landlord the actual reasonable cost of all required repairs,
including structural repairs. Tenant shall commit no act of waste and shall take
good care of the Demised Premises and the equipment affixed thereto and stored
therein, shall maintain the Demised Premises in good condition and state of
repair (including the components of the electrical and HVAC system which
exclusively serve the Demised Premises, but otherwise excluding the Building
systems) and, upon the Expiration Date or other termination of this Lease, shall
deliver up the Demised Premises in good order and condition, wear and tear from
a reasonable use thereof excepted. Landlord shall perform, or cause to be
performed, all such maintenance and repairs and Tenant shall pay to Landlord the
reasonable costs incurred therefor promptly upon demand as Additional Rent.

                (b)  Tenant, at Tenant's expense, shall promptly comply in all
material respects with all laws, rules, regulations and ordinances, of all
governmental authorities or agencies having jurisdiction over the Demised
Premises, and of all insurance bodies (including, without limitation, the Board
of Fire Underwriters), at any time duly issued or in force applicable to the
Demised Premises or any part thereof or to Tenant's use thereof, including,
without limitation the Americans with Disabilities Act, ("Laws" or, as the
context requires, "laws"); provided that Tenant shall not be deemed to have
complied with such Laws in all material respects in the event that Landlord
would have any liability thereunder as a result of such non-compliance.

                (c)  Landlord, at Landlord's expense, shall promptly comply with
all Laws applicable to the Common Areas and the Land. Subject to the releases
and waivers of subrogation contained in or required by this Lease, Landlord
shall indemnify and hold Tenant harmless from and against any expense
(including, without limitation reasonable attorneys fees), loss, liability or
damages (excluding consequential damages) suffered or incurred by Tenant as a
result of Landlord's failure to comply with all laws applicable to the Common
Areas. Landlord represents that it has received no notice of any violation of
Laws applicable to the Common Areas.


          6.    Tenant Improvements, Alterations and Installations.
                -------------------------------------------------- 

                (a)  With the exception of Tenant's trade fixtures, furniture
and other personalty (including computer and other office equipment and
modular/open plan furniture), all fixtures, equipment, improvements,
alterations, installations which are attached to the Demised Premises, and any
additions and appurtenances made by Tenant to the Demised Premises, shall become
the property of Landlord upon installation. Not later than the last day of the
Term, Tenant shall, at its expense, remove from the Demised Premises all of its
trade fixtures, furniture and other personal property and such improvements as
Landlord elects to have removed;

                                     - 11 -
<PAGE>
 
provided, however, that Tenant shall not be required to remove any improvements
or fixtures contemplated by the Final Plans  (as defined in Exhibit B) or any
improvements or fixtures of similar character which become part of the Demised
Premises as a result of an expansion thereof in accordance with the rights
granted Tenant under Paragraphs 32 and 33 of this Lease.  Tenant, at its sole
cost and expense, shall repair injury done by or in connection with the
installation or removal of such improvements.   Any equipment, fixtures, goods
or other property of Tenant not removed by Tenant upon the termination of this
Lease, or upon any quitting, vacating or abandonment of  the Demised Premises by
Tenant shall  be considered as abandoned and Landlord shall have the right,
without any notice to Tenant, to sell or otherwise dispose of the same, at the
expense of Tenant, and shall not be accountable to Tenant for any part of the
proceeds of such sale, if any, unless the proceeds of such sale exceed the total
amount of any sums due to Landlord under this Lease.  Landlord may have any such
property stored at Tenant's risk and expense.

                (b)  Tenant, without Landlord's prior consent, shall have the
right to make non-structural alterations, installations, additions or
improvements in or to the Demised Premises that (i) do not require a building
permit to be issued by any governmental authority to legally make same, and (ii)
do not affect any existing-building systems outside the Demised Premises and do
not impair or adversely affect any existing building systems within the Demised
Premises. No other alterations, installations, additions or improvements
(structural or non-structural) shall be made by Tenant without Landlord's
express prior written approval. Landlord agrees that approval of alterations,
installations and improvements of a non-structural nature and which do not
affect any building systems shall not be unreasonably withheld. Tenant shall
give Landlord prior written notice of any proposed alterations, installations,
additions or improvements (hereinafter called "Alterations") with copies of
proposed plans and as-built plans upon completion of the Alterations. At the
time of granting its approval of any Alterations, Landlord shall notify Tenant
of any such Alterations which must be removed at the expiration of the Term as
provided in Paragraph 6(a) above. All Alterations shall be done at Tenant's sole
expense and the making thereof shall not interfere with the use of the Building
by other tenants. Tenant agrees to indemnify, defend and hold harmless Landlord
from any and all costs, expenses, claims, causes of action, damages and
liabilities of any type or nature whatsoever (including, but not limited to,
reasonable attorneys' fees and costs of litigation) arising out of or relating
to the making of the Alterations by Tenant. Nothing herein contained shall be
construed as constituting the permission of Landlord for a mechanic or
subcontractor to file a lien claim against the Demised Premises and Tenant
agrees to secure the removal of or bond against any such lien which a contractor
purports to file against the Demised Premises as provided in Paragraph 30(g) of
this Lease. All such Alterations shall be effected in compliance with all
applicable laws, ordinances, rules and regulations of government bodies having
or asserting jurisdiction over the Demised Premises.

          7.    Various Negative Covenants by Tenant. Tenant agrees that it 
                ------------------------------------
shall not, without Landlord's prior written consent:

                (a)  do anything in or near the Demised Premises which will
increase the rate of fire insurance on the Building, provided that Tenant's use
of the Demised Premises in the manner allowed under Paragraph 1(c) hereof shall
not be deemed to cause such increase;

                (b)  permit the accumulation of waste or refuse matter in or
near the Demised Premises, except in containers provided therefor;

                (c)  mortgage, hypothecate, pledge or encumber this Lease in
whole or in part;

                                     - 12 -
<PAGE>
 
                (d)  permit any signs, lettering or advertising matter to be
erected or attached to the Demised Premises which is visible from outside of the
Demised Premises except as expressly permitted herein; or

                (e)  encumber or obstruct the Common Areas surrounding the
Demised Premises, nor cause same to be encumbered or obstructed, nor encumber or
obstruct any access ways to the Demised Premises, nor cause same to be
encumbered or obstructed.

          8.    Various Affirmative Covenants of Tenant.      Tenant covenants
                ---------------------------------------            
and agrees that Tenant will:

                (a)  At any time and from time to time execute, acknowledge and
deliver to Landlord, or to anyone Landlord shall designate, within ten (10)
business days of receipt of request therefor, a tenant estoppel certificate in
form reasonably acceptable to Landlord or financial institutions requesting the
same relating to matters customarily included in tenant estoppel certificates.
Tenant shall not be required to execute any estoppel certificate which would
result in a alteration of Tenant's rights and obligations under this Lease.

                (b)  Faithfully observe and comply with the rules and
regulations annexed hereto and made a part hereof as Exhibit C and such
additional rules and regulations as Landlord may hereafter at any time or from
time to time communicate in writing to Tenant, and which, in the reasonable
judgment of Landlord, shall be necessary or desirable for the reputation,
safety, care or appearance of the Building or the Complex, or the preservation
of good order therein, or the operation or maintenance of the Building or
Complex, or the equipment thereof, or the comfort of tenants or others in the
Building or Complex; provided, however, that in the case of any conflict between
the provisions of this Lease and any such rule or regulation, the provisions of
this Lease shall control. Nothing contained in this Lease shall be construed to
impose upon Landlord any duty or obligation to enforce the rules and regulations
or the terms, covenants or conditions in any other lease as against any other
tenant, and Landlord shall not be liable to Tenant for violation of any rule or
regulation by any other tenant, its employees, agents, visitors, invitees,
subtenants or licensees. Notwithstanding the foregoing, Landlord shall not
enforce such rules and regulations against Tenant, or fail to enforce the same
against other tenants in the Building, in a manner which would be unreasonable
and discriminatory as to Tenant.


          9.    Building Directory and Signage.   Provided that Landlord is able
                ------------------------------                                  
to obtain the necessary governmental permits and approvals to construct an
additional Building monument sign located on Campus Drive at the entrance to the
Building or to expand the existing sign, Landlord shall add Tenant's name at the
top of said additional or expanded Building monument sign.  Landlord agrees to
make commercially reasonable efforts to secure such permits and approvals.
Landlord's inability to obtain such governmental permits and approvals shall not
entitle Tenant to an offset or abatement of rent of any kind hereunder or
otherwise permit Tenant to avoid compliance with all terms, covenants and
conditions of this Lease.   If Landlord is unable to obtain such governmental
permits and approvals, Landlord shall reconfigure the existing monument sign to
add Tenant's name to the list of tenants presently contained on said sign.
Tenant shall be permitted to display its corporate name at the entrance of the
Demised Premises and on all Building directories.

                                     - 13 -

          10.   Casualty and Insurance.
                ---------------------- 

                (a)  In the event of partial or total destruction, by reason of
fire or any other cause, of (i) the Demised Premises or (ii) the Building or any
portion thereof which renders the Demised Premises untenantable, Landlord shall
promptly restore and rebuild (i) the Demised Premises to the standard set forth
in the work letter specifications contained in Exhibit B-1 or (ii) the Building
or such portion thereof as needed to make the Demised Premises tenantable to the
standard existing immediately prior to the occurrence of such fire or other
casualty, at Landlord's expense, unless, subject to the immediately following
sentence, Landlord elects by notice to Tenant within sixty (60) days of said
destruction not to restore and rebuild the Demised Premises and/or the Building,
and, in such case, upon a date specified in said notice by Landlord, this Lease
shall terminate. Landlord may elect to terminate this Lease only if (i) Landlord
is electing to terminate the leases of all tenants similarly situated and
affected by such casualty, or (ii) if such casualty occurs during the last
twelve (12) months of the Term (or, if Tenant has exercised its option to renew
this Lease, if such casualty occurs during the last twelve (12) months of the
final renewal Term). If Landlord elects to restore and rebuild the damage, then
during the period of restoration, Landlord shall notify Tenant of the estimated
time period for completing such restoration and Tenant shall be relieved of the
obligation to pay that portion of the rent herein reserved which relates to the
area of the Demised premises which has been rendered untenantable. If the damage
to the Demised Premises is such that Landlord reasonably estimates that the
restoration of the Demised Premises would require a period of time in excess of
eight (8) months after the date of Landlord's notice, then Tenant shall have the
right to terminate this Lease upon notice to Landlord given within twenty (20)
days after the date that Landlord notifies Tenant of the estimated time period
required for the restoration of the Demised Premises. If for any reason
(including force majeure) Landlord fails to complete the restoration of the
Demised Premises within twelve (12) months of the date on which the casualty
occurs, Tenant may terminate this Lease by giving Landlord written notice of
Termination prior to the completion of the restoration of the Demised Premises.
In the event of a casualty which renders the entire Demised Premises
untenantable which is restored and rebuilt by Landlord, Landlord shall give
Tenant fifteen (15) days notice prior to the completion of the restoration and
re-commencement of the obligation to pay rent hereunder.

          (b)   Tenant shall, at Tenant's sole cost and expense, except to the
extent prohibited by law with respect to workmen's compensation insurance, for
the mutual benefit of Landlord and Tenant and any Additional Insured (as
hereinafter defined) or any other additional insured as Landlord may from time
to time determine, including the lessors under any ground leases or underlying
leases and any mortgagees, maintain or cause to be maintained; (i) comprehensive
general liability insurance, including but not limited to, premises, bodily
injury, personal injury and contractual liability coverages (provided that
contractual liability coverage shall be required only if available at
commercially reasonable rates) for any and all damage or injury resulting from
any act or omission on the part of Tenant or Tenant's contractors, licensees,
agents, visitors or employees on or about the Demised Premises, including such
claims arising out of the construction of improvements on the Demised Premises,
such insurance to afford protection in the amount of Three Million Dollars
($3,000,000) with respect to injury or death to any one person or to any number
of persons or property damage arising out of a single occurrence, subject to
customary exclusions and to customary and reasonable deductibles; (ii) workmen's
compensation insurance covering all persons employed in connection with the
construction of any improvements by Tenant and the operation of its business
upon the Demised Premises. In the event that Landlord, at any time but not more
often than twice during the Term, reasonably deter-

                                     - 14 -
<PAGE>
 
mines that Tenant's insurance coverage is inadequate, based upon the coverages
being required by landlords of comparable buildings in the general geographic
area of the Building, Landlord shall have the right to require Tenant to
increase its insurance coverage; provided, however,  that such determination
shall not be made arbitrarily or discriminatorily as to Tenant in the context of
Landlord's treatment of other tenants in the Building.  All such insurance
shall, to the extent permitted by law, name any mortgagees and ground lessors of
the Land and the Building and their successors and assigns, as additional
insureds (the "Additional Insureds") and shall be written by an insurance
carrier authorized to do business in the State of New Jersey, which shall be
reasonably satisfactory to Landlord.

                (c)  Prior to the Commencement Date, and at least thirty (30)
days prior to the expiration date of any policy, Tenant shall furnish evidence
of such insurance and of the payment of the premiums thereon to Landlord. Such
insurance shall be in form reasonably satisfactory to Landlord and, without
limitation, shall provide that no cancellation or lapse thereof or change
therein shall be effective until after thirty (30) days' written notice to
Landlord at the address specified in Paragraph 18 of this Lease. Tenant waives
all rights of recovery against Landlord and the Additional Insureds for any
loss, damages, or injury of any nature for which Tenant is insured.

                (d)  During the Term, Tenant shall maintain in effect in each
insurance policy required under this Lease that relates to property damage a
waiver of subrogation in favor of Landlord and the Additional Insureds from
its then-current insurance carriers, and shall at all times furnish evidence of
such currently effective waiver to Landlord.  Such waiver shall be in a form
reasonably satisfactory to Landlord and, without limitation, shall provide that
no cancellation or lapse thereof or change therein with respect to any coverages
or conditions required in this Paragraph 10 shall be effective until after
thirty (30) days' written notice to Landlord at the address specified in
Paragraph 18 of this Lease.   During the term of this Lease, Landlord shall
maintain in effect in each insurance policy insuring the Building, the Land or
the Complex Land that relates to property damage a waiver of subrogation in
favor of Tenant from its then-current insurance carriers, and shall at all times
furnish evidence of such currently effective waiver to Tenant.  Such waiver
shall be in a form reasonably satisfactory to Tenant and, without limitation,
shall provide that no cancellation or lapse thereof shall be effective until
after thirty (30) days' written notice to Tenant at the address, specified in
Paragraph 18 of this Lease.

                (e)  Each insurance policy required to be maintained under this
Lease shall state that with respect to the interest of Landlord and the
Additional Insureds the insurance maintained pursuant to each such policy shall
not be invalidated by any action or inaction of Tenant and shall insure Landlord
and the Additional Insureds regardless of any breach or violation of any
warranties, declarations, conditions or exclusions by Tenant.

                (f)  Each insurance policy required to be maintained under this
Lease: (i) shall state that the insurance provided thereunder is primary
insurance without any right of contribution from any other insurance which may
be carried by or for the benefit of Landlord or the Additional Insureds; and
(ii) shall recognize the indemnification set forth in Paragraph 11 of this
Lease.

                (g)  Landlord agrees to maintain (i) comprehensive general
liability insurance in the minimum amount of One Million Dollars ($1,000,000)
single limit coverage, and (ii) insurance against loss or damage by fire, and
such other risks as may be included in the standard form of All Risk coverage,
in amounts required by Landlord's first mortgagee or, if none, amounts suffi-

                                     - 15 -
<PAGE>
 
cient to enable Landlord to obtain physical replacement cost coverage.

     11.  Indemnification.
          --------------- 

          Subject to the releases and waivers of subrogation contained in or
required by this Lease, Tenant shall indemnify, defend and hold harmless
Landlord and the Additional Insureds, from and against any expense (including,
without limitation, reasonable attorneys' fees), loss, liability or damages
suffered or incurred as a result of the negligent acts or omissions or the
willful misconduct of Tenant or Tenant's agents,  servants,  invitees,
contractors or employees.  The liability of Tenant to indemnify Landlord,  as
hereinabove set forth,  (i)  shall not extend to liability resulting solely from
the negligence of Landlord or Landlord's agents or employees, (ii) shall be in
proportion to Tenant's allocable share of any joint negligence or willful
misconduct with Landlord, and (iii) shall not extend to any matter against which
Landlord shall be effectively protected by insurance; provided, however, that if
any such liability shall exceed the amount of the effective and collectable
insurance in question, the said liability of Tenant shall apply to such excess.
If the obligations or liabilities of Tenant under the provisions of this
Paragraph 11 are qualified or contradicted by the specifically expressed
provisions of other paragraphs or clauses of this Lease, this Paragraph 11,
shall be deemed and construed to be modified or controlled by such other
paragraphs or clauses.

     12.  Non-Liability of Landlord.  Landlord shall not be liable for (and
          -------------------------
Tenant shall make no claim for) any property damage or personal injury which may
be sustained by Tenant or any other person as a consequence of the failure,
breakage, leakage, inadequacy, defect or obstruction of the water, plumbing,
steam, sewer, waste or soil pipes, roof drains, leaders, gutters, valleys,
downspouts, or the like or of the electrical, gas, power, conveyor,
refrigeration, sprinkler, air conditioning or heating systems, elevators or
hoisting equipment; or by reason of the elements; or resulting from the
carelessness, negligence or improper conduct on the part of any other tenant of
Landlord, or Tenant's or any other tenant's agents, employees, guests,
licensees, invitees, sub-tenants, assignees or successors; or attributable to
any interference with, interruption or failure of any services or utilities to
be furnished or supplied by Landlord. Tenant shall give Landlord prompt written
notice of the occurrence of any events set forth in this Paragraph 12.

     13.  Remedies and Termination Upon Tenant Default.
          -------------------------------------------- 

          (a)  In the event that:

               (1) Tenant shall default in the payment of any Fixed Rent, or any
Additional Rent, or other charge payable hereunder by Tenant to Landlord, on any
date upon which the same becomes due, and such default shall continue for five
(5) days after Landlord shall have given Tenant a written notice specifying such
default; or

               (2) Tenant shall default in the due keeping, observing or
performing of the covenants, agreements, terms, provisions or conditions
contained in Paragraph 1(c) of this Lease on the part of Tenant to be kept,
observed or performed and if such default shall continue and shall not be
remedied by Tenant within two (2) business days after Landlord shall have given
to Tenant a written notice specifying the same; or

               (3) Tenant shall default in the due keeping, observing or
performing of any covenant, agreement, term, provision or condition of this
Lease on the part of Tenant to be kept, observed or performed, other than a
default of the character referred to in clauses (1) or (2) of this Paragraph
13(a), and if such

                                    - 16 -
<PAGE>
 
default shall continue and shall not be remedied by Tenant within twenty (20)
days after Landlord shall have given to Tenant a written notice specifying the
same (unless such default is such that it could not reasonably be cured within a
twenty (20) day period and Tenant shall commence to make a good faith effort to
cure such default within said twenty (20) day period and shall diligently
proceed to completion); or

               (4) Should Tenant be evicted by summary proceedings or otherwise;

then, Landlord may, in addition to any other remedies herein contained, as may
be permitted by law, without being liable for prosecution therefor, or for
damages, reenter the Demised Premises and have and again possess and enjoy the
same; and as agent for Tenant or otherwise, re-let the Demised Premises and
receive the rents therefor and apply the same first to the payment of such
expenses, reasonable attorney fees and costs, as Landlord may have been put to
in re-entering and repossessing the same and in making such repairs and
alterations as may be necessary and second to the payment of the rents due
hereunder. Tenant shall remain liable for such rents as may be in arrears and
also the rents as may accrue subsequent to the re-entry by Landlord to the
extent of the difference between the rents reserved hereunder and the rents, if
any, received by Landlord during the remainder of the unexpired Term hereof,
after deducting the aforementioned expenses, fees and costs; the same to be paid
as such deficiencies arise and are ascertained each month. Landlord, at its
option, may require Tenant to pay in a single lump sum payment, at the time of
such termination or re-entry, as the case may be, a sum which represents the
present value (using a discount rate equal to the Prime Rate) of the excess of
the aggregate of the Fixed Rent which would have been payable by Tenant for the
period commencing with such termination or re-entry, as the case may be, and
ending on the originally fixed Expiration Date of the Term, over the aggregate
rental value of the Demised Premises for the same period. Landlord shall make
commercially reasonable efforts to mitigate damages in the event of a default by
Tenant.

          (b)  Upon the occurrence of any of the contingencies set forth in the
preceding subparagraph (a) of this Paragraph 13, or should Tenant be adjudicated
a bankrupt or insolvent, or placed in receivership, or should proceedings be
instituted by or against Tenant for bankruptcy,  insolvency,  receivership,
agreement of composition, or assignment for the benefit of creditors (and, if
the proceedings are initiated against Tenant, the same are not vacated within
ninety (90) days of their initiation), or if this Lease or the estate of Tenant
hereunder shall pass to another unaffiliated entity by virtue of any court
proceedings, writ of execution, levy, sale, or by operation of law, Landlord
may, if Landlord so elects, at any time thereafter, terminate this Lease and the
Term hereof, upon giving to Tenant or to any trustee, receiver, assignee or
other person in charge of or acting as custodian of the assets or property of
Tenant, five (5) days' notice in writing of Landlord's intention so to do.
Upon the giving of such notice, this Lease and the Term hereof shall end on the
date fixed in such notice as if the said date was the Expiration Date; and
Landlord shall have the right to remove all persons, goods, fixtures and
chattels therefrom, by force or otherwise without liability for damages.


     14.  Remedies Cumulative; Non-Waiver.
          ------------------------------- 

The various rights, remedies, options and elections expressed herein are
cumulative and the failure of either party to enforce strict performance by the
other of the conditions and covenants of this Agreement, to exercise any
election or option, or to resort or have recourse to any remedy herein
conferred, or the acceptance by Landlord of any installment of rent after any
breach by Tenant, in any one or more instances, shall not be construed or deemed
to be

                                     - 17 -
<PAGE>
 
a waiver or a relinquishment for the future of any such conditions and
covenants, options, elections or remedies, but the same shall continue in full
force and effect.


     15.  Services; Electric Energy
          -------------------------

          (a)  Landlord shall: (i) supply heat, ventilation and air conditioning
to the Demised Premises and the Common Areas during Business Hours in accordance
with the HVAC specifications contained in Exhibit B-1 attached hereto; (ii)
provide snow and ice removal for the parking area, sidewalks and driveways in a
reasonably expeditious manner;  (iii)  provide refuse removal from a dumpster to
be provided on site to be used for normal paper waste attendant to an office
building; and (iv) provide security services in accordance with the
specifications attached hereto as Exhibit I. "Business Hours" as used in this
Lease, means the generally customary daytime business hours of Tenant but not
before 8:00 A.M. or after 6:00 P.M. on weekdays and 8:00 A.M. to 1:00 P.M. on
Saturdays, and not including Sundays and Building Holidays (except that Landlord
shall provide heat, ventilation and air conditioning service to the Demised
Premises and building security to the Building on Good Friday without charging
Tenant for overtime services). Tenant shall have access to the Demised Premises
twenty-four (24) hours a day, seven (7) days a week at no additional cost except
when overtime services are required as provided in Paragraph 15(b). Tenant
agrees at all times to cooperate fully with Landlord and to abide by all the
regulations and requirements which Landlord may prescribe for the proper
functioning and protection of such air conditioning system. Landlord shall clean
the Demised Premises in accordance with the cleaning schedule annexed hereto as
Exhibit D. The cost of the services and utilities provided pursuant to this
Paragraph 15(a) is included in Expenses as defined in Paragraph 3(a).

          (b)  Provided Tenant is not then in default of this Lease beyond the
expiration of any applicable grace period, Landlord shall provide to Tenant
overtime services and utilities when and to the extent reasonably requested by
Tenant, or when activated by Tenant's use of an overtime thermostat and time
clock, and in accordance with such reasonable conditions as shall be determined
by Landlord.    Tenant  shall  pay to Landlord,  as Additional Rent, a charge
determined by Landlord for such additional service and utilities, which charge
shall cover all costs and expenses of Landlord in providing such overtime
services, including, without limitation, the cost of the utility usage, the cost
of maintenance, repairs and inspections of such building systems and employee
and administrative costs related to such services.  Such charge shall constitute
a direct charge to Tenant and not an Expense as defined in Paragraph 3.  During
the Initial Year, such charge shall be Fifty-five Dollars ($55) per hour.
Increases in such charge after the Initial Year shall be based upon increases in
the costs incurred by Landlord in supplying such service without mark-up.

          (c)  Landlord reserves the right, without liability to Tenant and
without constituting any claim of constructive eviction, to stop or interrupt
any heating, lighting, ventilating, air conditioning, gas, steam, power,
electricity, water or other service and to stop or interrupt the use of any
building or Building facilities at such times as may be necessary and for as
long as may reasonably be required by reason of accidents, strikes, or the
making of repairs, alterations or improvements, or inability to secure a proper
supply of fuel, gas, steam, water, electricity, labor or supplies, or by reason
of any other similar or dissimilar cause beyond the reasonable control of
Landlord.  No such stoppage or interruption shall entitle Tenant to any
diminution or abatement of rent or other compensation nor shall this Lease or
any of the obligations of Tenant be affected or reduced by reason of any such
stoppage or interruption; provided, however, that if such stoppage

                                     - 18 -
<PAGE>
 
is within the control of Landlord, the rent reserved hereunder shall abate from
and after the fifth (5th) business day of such stoppage or interruption until
Landlord shall restore service. Further, if such stoppage or interruption
continues for a period of six (6) months, Tenant shall have the right to
terminate this Lease by giving written notice of termination to Landlord prior
to the restoration of service.

          (d) Landlord shall furnish to Tenant, through the transmission
facilities installed in the Demised Premises, electric energy to be used by
Tenant, at Tenant's expense as provided for in this Paragraph 15, in the Demised
Premises in such reasonable quantity as shall be sufficient to meet Tenant's
ordinary business needs for lighting and the operation of its business machines,
as specified on Exhibit B-1, including, without limitation, photocopy equipment
and computer and data processing equipment, provided that Landlord shall not be
obligated to provide such electrical energy in any amount in excess of a total
connected load of six (6) watts of electric consumption for all purposes per
square foot of rentable area.

          (e) Landlord shall, prior to the Commencement Date, at Landlord's sole
cost and expense, install a separate electrical meter so as to measure the
consumption of electricity in the Demised Premises. Landlord shall charge Tenant
for such electrical usage at Landlord's actual cost therefor (based upon the
average kilowatt hour cost of each invoice) without mark-up and Tenant shall pay
such amount to Landlord as Additional Rent hereunder within thirty (30) days of
Landlord's giving Tenant notice of the amount then due.

          (f) If Landlord, by operation of law or as a result of the order of
any governmental authority or utility, is required to discontinue furnishing
electric energy to Tenant, Tenant shall arrange to obtain electric energy
directly from the public utility company furnishing electric service to the
Building. Such electric energy may be furnished to Tenant by means of the then
existing Building system feeders, risers and wiring to the extent that the same
are available, suitable and safe for such purposes.   All meters and additional
panel boards, feeds, risers, wiring and other conductors and equipment which may
be required to obtain electric energy directly from such public utility company
shall be installed by Landlord at Tenant's expense.  There shall be no
discontinuance of the furnishing of electric current to the Demised Premises by
Landlord until Tenant has completed its arrangements to obtain electric current
directly from the public utility company furnishing electric current to the
Building so that there is no interruption in the continuity of electric service.

          (g) In the event that Tenant shall require electric energy for use in
the Demised Premises in excess of the quantity to be initially furnished as
herein provided and if, in Landlord's judgment, such excess requirements cannot
be furnished unless additional risers, conduits, feeders, switchboards and/or
appurtenances are installed in the Building, Landlord, upon written request of
Tenant, shall proceed with reasonable diligence to install such additional
risers, conduits, feeders, switchboards and/or appurtenances, provided the same
and the use thereof shall be permitted by applicable laws and insurance
regulations and shall not cause permanent damage or injury to the Building or
the Demised Premises, or cause or create a dangerous or hazardous condition, or
entail excessive or unreasonable alterations or repairs, or interfere with or
disrupt other tenants or occupants of the Building, and Tenant agrees to pay all
costs and expenses incurred by Landlord in connection with such installation.



                                     - 19 -
<PAGE>
 
          (h) In order that Landlord may at all times have all necessary
information which it requires in order to maintain and protect its equipment,
Tenant agrees that Tenant shall not make any material alteration or material
addition to the electrical equipment and/or appliances in the Demised Premises
without the prior written consent of Landlord in each instance and shall
promptly advise Landlord of any other alteration or addition to such electrical
equipment and/or appliances.   Tenant agrees to advise Landlord in writing as to
any material change in the periods of use of the lighting fixtures and Tenant's
business machines and equipment.

          (i) Landlord shall in no way be liable or responsible to Tenant for
any loss or damage or expense which Tenant may sustain or incur by reason of any
failure, inadequacy or defect in the character, quantity or supply of electric
energy furnished to the Demised Premises except for actual damage other than
property damage suffered by Tenant by reason of any negligence of Landlord.

     16.  Subordination.   This Lease shall be subject and subordinate in all
          -------------                                                      
respects to any underlying leases, ground leases, licenses or agreements, and to
all mortgages which may now or hereafter be placed on or affect such leases,
licenses or agreements or the Land or the Demised Premises and also to all
renewals, modifications, consolidations and extensions of such underlying,
leases, ground lease, licenses, agreements, and mortgages, so long as each such
underlying landlord, ground lessor, or mortgagee shall provide to Tenant a
subordination, attornment and nondisturbance agreement substantially in the form
attached hereto and made part hereof as Exhibit E. Tenant shall execute and
deliver such further instruments confirming such subordination and non-
disturbance agreement as may be reasonably required by any holder of any such
mortgage or by a lessor, licensor or party to an agreement under any such
underlying lease, ground lease, license or agreement, respectively. If any
underlying lease, ground lease, license or agreement to which this agreement is
subject and subordinate terminates, or if any Mortgage to which this lease is
subordinate is foreclosed, Tenant shall, on timely request, attorn to the holder
of the reversionary interest or to the Mortgagee in possession, as the case may
be. Landlord represents that, on the date of the execution of this Lease, there
are no underlying leases, ground leases or mortgages encumbering the Building
with the exception of a construction loan mortgage held by the First National
Bank of Chicago. The parties shall execute and deliver to each other a
subordination, attornment and nondisturbance agreement substantially in the form
of that in Exhibit E with respect to said construction loan mortgage prior to
the Commencement Date.


     17.  Curing Tenant's Defaults.  If Tenant shall fail or refuse to comply
          ------------------------
with and perform any conditions and covenants of this Lease after notice and the
expiration of the applicable cure period, Landlord may, if Landlord so elects,
carry out and perform such conditions and covenants, at the cost and expense of
Tenant, and the said cost and expense shall be payable on demand, or, at the
option of Landlord, shall be added to the installment of Monthly Fixed Rent due
immediately thereafter but in no case later than one month after such demand,
whichever occurs sooner, and shall be due and payable as such. This remedy shall
be in addition to such other remedies and Landlord may have hereunder by reason
of the breach of Tenant of any of the covenants and conditions in this Lease
contained.


     18.  Notices.  Any notice, demand, statement or other communication which
          -------
under the terms of this Lease or under any statute or law must or may be given
shall be given by hand delivery, or by registered or certified mail, return

     19.  Quiet Enjoyment.   Landlord covenants that Tenant upon keeping and
          ---------------                                                   
performing each and every covenant, agreement, term, provision and condition
herein contained on the part and on behalf of Tenant to be kept and performed,
shall quietly enjoy the Demised Premises without hindrance or molestation by
Landlord or by any other person lawfully claiming by, through or under the same,
subject to the covenants, agreements, terms, provisions and conditions of this
Lease and the effects of the application of same. The foregoing covenant is and
shall be, in addition to and not in derogation of Tenant's implied right to
quiet enjoyment.


     20.  Security Deposit.
          ---------------- 

          (a) Tenant has this day deposited with Landlord the Security Deposit
for the payment of the Fixed Rent, Additional Rent and other charges hereunder
and the full and faithful performance by Tenant of the covenants and conditions
on the part of Tenant to be performed.   Said sum shall be returned to Tenant,
without interest, after the expiration of the term hereof, provided that Tenant
has fully and faithfully performed all such covenants and conditions and is not
in arrears in Fixed Rent, Additional Rent and other charges.  During the term
hereof, Landlord may, if Landlord so elects, have recourse to such security, to
make good any default by Tenant, in which event Tenant shall, on demand,
promptly restore said security to its original amount.   Liability to repay said

                                     - 21 -
<PAGE>
 
security to Tenant shall run with the reversion and title to the Demised
Premises, whether any change in ownership thereof be by voluntary alienation or
as the result of judicial sale, foreclosure or other proceedings, or the
exercise of a right of taking or entry by any mortgagee. Landlord shall assign
or transfer said security, for the benefit of Tenant, to any subsequent owner or
holder of the reversion or title to Demised Premises, in which case the assignee
shall become liable for the repayment thereof as herein provided, and the
assignor shall be deemed to be released by Tenant from all liability to return
such security.

          (b) If on the thirty (30) month anniversary of the Commencement Date,
and provided that (i) Tenant's financial condition has not, in the reasonable
opinion of Landlord, declined in any material respect below the condition
existing on the date of the execution of this Lease, (ii) Tenant has not made
more than two (2) late payments of Fixed or Additional Rent beyond the
applicable grace period, and (iii) Tenant is not in default under any other
term, covenant or condition of this Lease beyond the applicable cure period,
the Security Deposit shall be reduced to an amount equal to the monthly Fixed
Rent, and Landlord shall refund the excess over such amount to Tenant.

          (c) If on the five (5) year anniversary of the Commencement Date, and
provided that (i) Tenant's financial condition has not, in the reasonable
opinion of Landlord, declined in any material respect below the condition
existing on the date of the execution of this Lease, (ii) Tenant has not made
more than two (2) late payments of Fixed or Additional Rent beyond the
applicable grace period, and (iii) Tenant is not in default under any other
term, covenant or condition of this Lease beyond the applicable cure period, the
Security Deposit shall be returned to Tenant by Landlord; provided, however,
that in the event of a default by Tenant hereunder with respect to Tenant's
obligation to pay Fixed or Additional Rent, Landlord may require, in addition to
such payments as are necessary to cure such default, that Tenant pay an amount
equal to twice the Fixed Monthly Rent to re-establish the Security Deposit.


     21.  Inspection and Entry by Landlord.
          -------------------------------- 

          (a) Tenant agrees to permit Landlord and Landlord's agents, employees
or other representatives to show the Demised Premises to any lessor under any
underlying lease or ground lease or any mortgagee or any persons wishing to rent
or purchase the same; provided that Tenant shall be given twenty-four (24) hours
prior telephonic notice.

          (b) Tenant agrees that, upon same day telephonic notice to Tenant
(except for routine maintenance), Landlord and Landlord's agents, employees or
other representatives, shall have the right to enter into and upon the Demised
Premises or any part thereof, at all reasonable hours, for the purpose of
inspecting the same, or reading meters, or performing maintenance, or making
such repairs or alterations therein as may be necessary for the safety and
preservation thereof.  This clause shall not be deemed to be a covenant by
Landlord nor be construed to create an obligation on the part of Landlord to
make such inspection or repairs.


     22.  Brokerage.  Tenant and Landlord warrant and represent to each other
          ---------
that neither has dealt with any broker or brokers regarding the negotiation of
this Lease other than the Designated Broker. Landlord agrees to pay the
commission due and payable to the Designated Broker as a result of the execution
of this Lease in accordance with the terms of a separate agreement between those
parties, and Landlord shall indemnify and hold Tenant harmless from any claim by
the Designated Broker with respect to such commission. Tenant and Landlord agree
to be responsible for

                                     - 22 -
<PAGE>
 
and to indemnify and hold the other harmless from and against any claim for a
commission or other compensation by any broker other than the Designated Broker
claiming to have negotiated with the indemnifying party with respect to the
Demised Premises or to have called the said Demised Premises to Tenant's
attention or to have called Tenant to Landlord's attention.

     23.  Parking.  Tenant shall have the right under this Lease to the
          -------
exclusive use of the Exclusive Spaces in the Building's executive garage and the
non-exclusive use of the Non-Exclusive Spaces in the parking lot of the Building
in compliance with such reasonable Rules and Regulations as Landlord may
promulgate from time to time. Landlord shall have the right to assign the
location of said non-exclusive parking spaces or may designate the location of
same from time to time. Landlord shall designate and assign to Tenant one (1)
additional Exclusive Space in the Building's executive garage, as and if such
space become available due to the expiration and non-renewal of other tenant's
leases in the Building. If Tenant takes additional space in the Building
pursuant to the rights afforded Tenant in Paragraphs 32 and 33 hereof, subject
to availability, Tenant shall also be allocated one additional Exclusive Space
in the executive garage for each additional ten thousand (10,000) square feet of
gross rentable area of office space leased by Tenant.


     24.  Renewal Option.
          -------------- 

          (a) Tenant is hereby granted three (3) successive options to renew
this Lease for a Renewal Term or five (5) years each, subject to the term of
this Paragraph 24. In the event that Tenant desires to renew this Lease, it
shall give notice in writing to Landlord of its intention to renew the Lease at
least fifteen (15) months prior to the Expiration Date and at least fifteen
(15) months prior to the expiration of each of the first two (2) Renewal Terms,
as the case may be. All of the terms and conditions of this Lease shall remain
in effect during each Renewal Term, except that (i) the Initial Year for
purposes of determining Tenant's Proportionate Share of any increase in Expenses
shall be adjusted to the year preceding the first year of the applicable Renewal
Term, and (ii) the annual Fixed Rent payable during each Renewal Term shall be
ninety-five percent (95%) of the annual fair market rental value of the Demised
Premises during the applicable Renewal Term based on comparable space in the
vicinity of the Demised Premises in comparable condition to that which the
Demised Premises will be in after completion of the Tenant Improvements (the
"Fair Market Value") as of the date which is thirteen (13) months prior to the
commencement date of such Renewal Term. The Fair Market Value of the Demised
Premises for purposes of subparagraph (a) of this Paragraph 24 shall take into
account the adjustment of the Initial Year as provided above and shall otherwise
be determined pursuant to the provisions of Paragraph 24(b). In no event shall
the annual Fixed Rent during any Renewal Term be less than the annual Fixed Rent
payable during the year preceding the first year of each such Renewal Term.

          (b) On or before the later to occur of (i) the fifteenth (15th) day
after Landlord's receipt of notice of Tenant's intention to renew this Lease or
(ii) the first day of the fifteenth (15th) month preceding the then Expiration
Date, Landlord Shall notify Tenant of Landlord's determination of the Fair
Market Value. Within fifteen (15) days after Tenant's receipt of Landlord's
determination, Tenant shall notify Landlord whether Tenant accepts or rejects
said determination. If Tenant objects to Landlord's determination, the parties
shall confer and negotiate over the next sixty (60) days in an attempt to
reconcile its differences over the Fair Market Value. If the parties are unable
to resolve the dispute within sixty (60) days after Landlord's receipt of
Tenant's objection, then Tenant shall have

                                     -23 -
<PAGE>
 
the right, at its discretion, to either rescind its notice of intention to renew
this Lease or to implement the appraisal process hereinafter described. If
Tenant elects to rescind its renewal notice, or if Tenant fails to give Landlord
notice of its election to implement the appraisal process by the first day of
the twelfth (12th) month precedinq the then Expiration Date, then in either case
Tenant shall be deemed to have waived its right to renew pursuant to the terms
of this Paragraph. If Tenant elects to implement the appraisal process, then
Landlord and Tenant each agree to be bound by the Fair Market Value determined
by said process. In the event Tenant has elected to implement the appraisal
process, then each party, at their own expense, shall designate an MAI or SREA
appraiser in the Morris County area who shall then determine and promptly report
to both parties in writing the Fair Market Value of the Demised Premises. If,
after receiving the appraisers' reports, the parties are unable to agree on the
Fair Market Value, both parties shall jointly appoint a separate MAI or SREA
appraiser who shall determine the Fair Market Value by selecting either
Landlord's appraiser's Fair Market Value determination or Tenant's appraiser's
Fair Market Value determination according to whichever of the two valuations is
closer to the actual Fair Market Value in the opinion of such third appraiser.
If Landlord's appraiser and Tenant's appraiser can not agree on the selection of
the third appraiser, such selection shall be made by the Morris County
Assignment Judge. The costs of such third appraiser shall be shared equally by
Landlord and Tenant.

          (c) It shall be a condition of the exercise or the option set forth in
this Paragraph 24, that at the time of the exercise of said option, Tenant shall
not be in default under this Lease beyond applicable grace periods.


     25.  Landlord's Inability to Perform. This Lease and the obligation of
          -------------------------------
Tenant to pay the rent hereunder and to comply with the covenants and conditions
hereof shall not be affected, curtailed, impaired or excused because of the
Landlord's inability to supply any service or material called for herein, by
reason of any rule, order, regulation or preemption by any governmental entity,
authority, department, agency or subdivision or for any delay which may arise by
reason of negotiations for the adjustment or any fire or other casualty loss or
because of strikes or other labor trouble or for any cause beyond the control of
the Landlord; provided; however, that this Paragraph 25 shall not affect
Tenant's right to an abatement of rent where such right is specifically provided
in another paragraph of this Lease.


                                  
     26.  Condemnation.
          ------------ 

          (a) In the event that the whole or the Demised Premises shall be
lawfully condemned or taken in any manner for any public or quasi-public use or
purpose or is transferred, under threat of condemnation, by Landlord to any
party having the right of condemnation (any of such acts are referred to herein
as "eminent domain"), this Lease and the term and estate hereby granted shall
forthwith cease and terminate as of the date of vesting of title (hereinafter
referred to as the "date of taking"), and Tenant shall have no claim against
Landlord for, or make any claim for the value of, any unexpired term of this
Lease, and the Fixed Rent and Additional Rent shall he apportioned as of such
date.

          (b) In the event that any part of the Demised Premises shall be so
condemned or taken, then this Lease shall be and remain unaffected by such
condemnation or taking, except that the Fixed Rent and Additional Rent
allocable to the part so taken shall be apportioned as of the date of taking,
and Tenant shall have no claim against Landlord for, or make any claim for the
value of, the portion of the unexpired Term of this Lease allocable to the part
so taken, provided, however, that in such event either party may elect to cancel
this Lease, provided that notice of


                                     - 24 -
<PAGE>
 
termination is given to the other party not later than sixty (60) days after the
date when title shall vest in the condemning authority. Upon the giving of such
notice, this Lease shall terminate on the thirtieth (30th) day following the
date of such notice and the Fixed Rent and Additional Rent shall be apportioned
as of such termination date and Tenant shall have no claim against Landlord for,
or make any claim for the value of, the unexpired Term of this Lease. Upon such
partial taking and this Lease continuing in force as to any part of the Demised
Premises, the Fixed Rent and Additional Rent shall be diminished by an amount
representing the part of the Fixed Rent and Additional Rent properly applicable
to the portion or portions of the Demised Premises which may be so condemned or
taken and the parking spaces allocable to the Demised Premises shall be reduced
proportionately. If, as a result of the partial taking (and this Lease
continuing in force as to the part of the Demised Premises not so taken), any
part of the Demised Premises not taken is damaged, Landlord agrees with
reasonable promptness to commence the work necessary to restore the damaged
portion to the condition existing immediately prior to the taking, and prosecute
the same with reasonable diligence to its completion. In the event Landlord and
Tenant are unable to agree as to the amount by which the Fixed Rent and
Additional Rent shall be diminished, the matter shall be determined by a
mutually acceptable third party. Pending such determination, Tenant shall pay to
Landlord the Fixed Rent and Additional Rent as fixed by Landlord, subject to
adjustment upon resolution of such dispute.

          (c) Nothing herein provided shall preclude Tenant from appearing,
claiming, proving and receiving in the condemnation proceeding Tenant's
reasonable and actual moving and relocation expenses and the value of trade
fixtures provided such claim shall be separate from and shall not adversely
affect Landlord's award.

          (d) Subject to the provisions of Paragraph 26(c), the entire award for
any act of eminent domain shall be paid to Landlord, and, in the event of a
partial taking, if this lease is not cancelled by either party pursuant to the
provisions of this Paragraph 26, Landlord, at Landlord's own expense, shall
restore the unaffected part of the Demised Premises to substantially the same
condition and tenantability as existed prior to the taking. Until said
unaffected portion is restored, Tenant shall be entitled to a proportionate
abatement of Fixed Rent and Additional Rent of that portion of the Demised
Premises which is being restored and is not usable until the completion of the
restoration or until the said portion of the Demised Premises is used by Tenant,
whichever occurs sooner.  Said unaffected portion shall be restored within a
reasonable time, provided, however, if Landlord is delayed by force majeure the
time for completion shall be extended for a period equivalent to the delay.  If
such partial taking shall occur in the last year of the Term, either party,
irrespective of the area of the space remaining, may elect to cancel this Lease
and the term hereby granted, provided such party shall, within sixty (60) days
after such taking, give notice to that effect, and upon the giving of such
notice, the Fixed Rent and Additional Rent shall be apportioned and paid to the
date of expiration of the term specified, which date shall be not more than
thirty (30) days after the date of such notice, and this Lease and the term
hereby granted shall cease, expire and come to an end upon the expiration of the
period specified in said notice.  If either party shall so elect to end this
Lease and the term hereby granted, Landlord need not restore any part of the
Demised Premises and the entire award for partial condemnation shall be paid to
Landlord, and Tenant shall have no claim to any part thereof.

     27.  Assignment and Subletting.
          ------------------------- 

          (a) In the event that Tenant desires to assign this Lease or sublease
the Demised Premises or any portion thereof to any other party, notice of such
desire shall be given to Landlord in writing at least sixty (60) days prior to
the proposed effective date of any such assignment or sublease.   Such notice
shall include,  in the case of a sublease, the area of the Demised Premises to
be sublet and the proposed term of such sublease. Landlord shall have the
option, exercisable within thirty (30) days of Landlord's receipt of Tenant's
notice of intent, to recapture this Lease, in the case of an assignment, or, in
the case of a sublease, to recapture the space intended to be sublet, if the
gross floor area of the space to be sublet exceeds (in the aggregate including
all prior subleases) thirty percent (30%) of the gross floor area of the Demised
Premises, such recapture to occur as of the proposed effective date set forth in
Tenant's notice.  In such event, Tenant shall be fully released from any and all
obligations hereunder with respect to the Demised Premises, in the case of an
assignment, or with respect to the space to have been sublet, in the case of a
sublease.  Any sale or other transfer, whether voluntary or involuntary, by
operation of law or otherwise (including, without limitation, by consolidation,
merger or reorganization), of a majority of the voting stock of Tenant, if
Tenant is a corporation, or a majority of the partnership interests in Tenant,
if Tenant is a partnership, shall be an assignment for purposes of this
Paragraph 27 whether such transfer is accomplished in one transaction or a
series of transactions; provided, however, that the initial public stock
offering by Tenant or a successor entity and subsequent sales of stock sold on a
nationally recognized exchange shall not constitute an assignment for purposes
of this Paragraph 27.

          (b) In the event that Landlord elects not to recapture the Demised
Premises or the portion thereof to be sublet as hereinabove provided, whichever
the case may be, Tenant may nevertheless assign this Lease or sublet the whole
or any portion of the Demised Premises, subject to the Landlord's prior written
consent, which consent shall not be unreasonably withheld and shall be granted
or denied within fifteen (15) days of receiving Tenant's request therefor
identifying the name and address of the proposed assignee or sublessee.
Landlord's failure to respond within said fifteen (15) day time period shall be
deemed to constitute consent. Any approval of such request shall be subject to
the consent of any mortgagee or ground lessor, which consent shall also be
granted or withheld within said fifteen (15) day period, and shall be subject to
the following terms and conditions:

              (1) The assignee shall assume, by written instrument, all of the
obligations of this Lease, and the sublessee shall agree, by written instrument,
to be subject to all of the obligations of this Lease (but only to the extent
applicable to the space sublet and for the term of the sublease), and a copy of
such agreement shall be furnished to Landlord within ten (10) days of its
execution.

              (2) Tenant and each assignee shall be and remain liable for the
observance of all of the covenants and provisions of this Lease including, but
not limited to, the payment of Fixed Rent, Additional Rent and other charges due
hereunder through the entire Term of this Lease, as the same may be renewed,
extended or otherwise modified.

              (3) Tenant shall promptly pay to Landlord fifty percent (50%) of
any consideration other than rent received for or in connection with any
assignment or sublease, however denominated (excluding the proceeds of the sale
of Tenant's personal property and trade fixtures at a price not in excess of
depreciated book value), and fifty percent (50%) of all of the rent, as and when
received, in excess of the rent required to be paid by Tenant for the area
assigned or sublet.


                                    - 26 -
<PAGE>
 
              (4) In any event, the acceptance by Landlord of any rent from any
of the subtenants or the failure of Landlord to insist upon the strict
performance of any of the terms, conditions and covenants herein from any
assignee or subtenant shall not release Tenant herein, from any and all of the
obligations herein during and for the entire term of this Lease.

              (5) The assignment or sublease shall provide that there shall be
no further assignments and/or subletting without Landlord's consent in
accordance with the provisions of this Paragraph 27.

          (c) Tenant shall pay the actual reasonable legal costs incurred by
Landlord, up to a maximum of Seven Hundred Fifty Dollars ($750) per request, to
cover its handling charges for each request for consent to any assignment or
sublet which is subsequently approved by Landlord, such payment to be made
within ten (10) days of Landlord's notice of approval. Tenant acknowledges that
its sole remedy with respect to any assertion that Landlord's failure to consent
to any assignment or sublet is unreasonable shall be the remedy of specific
performance and Tenant shall have no other claim or cause of action against
Landlord as a result of Landlord's actions in refusing to consent thereto.

          (d) Notwithstanding anything to the contrary contained in this Lease,
Tenant, without Landlord's prior written consent thereto and without being
subject to the provisions of this Paragraph 27, except subsection (b)(2) which
shall be applicable, shall have the right at any time and from time to time, to
assign this Lease or sublet all or a portion of the Demised Premises to, or
allow the Demised Premises to be otherwise occupied by (i) any parent,
subsidiary, affiliate, group, or division of Tenant, or to any purchaser of all
or substantially all of Tenant's assets, or to any entity which acquires all or
substantially all of the outstanding capital stock of Tenant; or (ii) any entity
arising from Tenant being restructured as a publicly held company; or (iii) any
entity arising as a result of a leveraged buyout, including any subsequent sales
of stock to the public or otherwise, as applicable.

     28.  Environmental Laws.
          ------------------ 

          (a) Tenant agrees to comply with all environmental laws, rules and
regulations, including, but not limited to, the Environmental Cleanup
Responsibility Act (N.J.S.A. 13:lK-6, et seg.)  ("ECRA")  applicable to the
                                      -- ---                                  
Demised Premises or to the Tenant's use or occupancy thereof. Tenant represents
to Landlord that Tenant's Standard Industrial Classification (SIC) Number is
2834. Tenant represents that its contemplated use of the Demised Premises is
consistent with those uses identified in N.J.A.C. 7:26B-l.8(a)2 and should
thereby qualify for the administrative office exemption from ECRA contained in
said regulation. Tenant shall not conduct any operations at the Demised Premises
that shall cause the Building or the Demised Premises to be deemed an
"industrial establishment" as presently defined in ECRA, or, in the alternative,
shall conduct its operations so as to continue to qualify for an exemption
therefrom.

          (b) Tenant hereby agrees to execute such documents Landlord reasonably
deems necessary and to cooperate in the making of such applications as Landlord
reasonably requires to assure compliance with ECRA. Tenant shall bear all costs
and expenses incurred by Landlord associated with any required ECRA compliance
resulting from Tenant's use of the Demised Premises, including, but not limited
to, state agency fees, engineering fees, clean-up costs, filing fees and
suretyship expenses; provided, however, that Tenant shall have no responsibility
for any such costs and expenses arising from (i) conditions at the Demised
Premises or on the Land existing prior to the Commencement Date, (ii) the
affirmative act or negligent omission of Landlord, or Landlord's agents or
employees, or (iii) the construction of the Building or the Demised

                                     - 27 -
<PAGE>
 
Premises by Landlord and the nature of the materials employed by Landlord with
respect thereto. In addition, Landlord shall be responsible for the cost of
obtaining a Letter of Non-Applicability under ECRA if the triggering event is
the sale or refinancing of the Building by Landlord, or any change in the
ownership or control of Landlord, or any other trigger resulting solely from the
actions of Landlord. As used in this Lease, ECRA compliance shall include
applications for determinations of nonapplicability by the appropriate
governmental authority. The foregoing undertaking shall survive the termination
or sooner expiration of the Lease and surrender of the Demised Premises and
shall also survive the sale, lease or assignment of the Demised Premises by
Landlord. Tenant shall promptly provide Landlord with copies of all material
correspondence, reports, notices, orders, findings, declarations and other
materials pertinent to Tenant's compliance at the Demised Premises and the New
Jersey Department of Environmental Protection and Energy's ("NJDEPE")
requirements under ECRA as they are issued or received by the Tenant.

          (c) Neither party hereto shall be permitted to generate, store,
manufacture, refine, transport, treat, dispose of, or otherwise allow to be
present on or about the Demised Premises, any Hazardous Substances with the sole
exception of those Hazardous Substances typically used in operating, cleaning or
maintaining a business office in quantities consistent with such use.  As used
herein, "Hazardous Substance" shall be defined as any "hazardous chemical",
"hazardous substance", "hazardous waste", or similar term as defined in the
Comprehensive Environmental Responsibility Compensation and Liability Act, as
amended (42 U.S.C. 9601, et seq.), ECRA, the New Jersey Spill Compensation and
Control Act, as amended, (N.J.S.A. 58:l0-23.llb, et seq.), any rules or
regulations promulgated thereunder, or in any other present or future applicable
federal, state or local law, rule or regulation dealing with environmental
protection.

          (d) Tenant agrees to indemnify and hold harmless Landlord and each
mortgagee of the Demised Premises from and against any and all liabilities,
damages, claims, losses, judgments, causes of action, costs and expenses
(including reasonable attorneys' fees) which may be incurred by Landlord or any
such mortgagee or threatened against the Landlord or such mortgagee, relating to
or arising out of any breach by Tenant of this Paragraph 28, which
indemnification shall survive the expiration or sooner termination of this
Lease.

          (e) Landlord represents that it has no knowledge of the storage or
disposal of Hazardous Substances anywhere on the Complex Land or any of the
Improvements thereon (i) except in compliance with all applicable federal, state
and local environmental laws, (ii) of a nature as would expose Tenant to any
claims or liabilities as a result of its use and occupancy of the Demised
Premises, or (iii) which would materially impair Tenant's use and occupancy of
the Demised Premises.  Landlord agrees to indemnify and hold Tenant harmless
from and against any and all liabilities, damages, claims, losses, judgments,
causes of action, costs and expenses (including reasonable attorneys' fees)
which may be incurred by Tenant as a result of (i) the existence of Hazardous
Substances in the Building or on the Land prior to the Commencement Date, or
(ii) the handling, storage or disposal of Hazardous Substances by Landlord or
Landlord's agents or employees in violation of any applicable federal, state or
local environmental laws.


     29.  Parties Bound.
          ------------- 

          (a) The covenants, agreements, terms, provisions and conditions of
this Lease shall bind and benefit the respective successors, assigns and legal
representatives of the parties hereto with the same effect as if mentioned in
each instance where a party

                                     - 28 -
<PAGE>
 
hereto is named or referred to except that no violation of the provisions of
Paragraph 7(c) hereof shall operate to vest any rights in any successor,
assignee or legal representative of Tenant and that the provisions of this
Paragraph 29 shall not be construed as modifying the conditions contained in
Paragraph 13 hereof.

          (b) Tenant acknowledges and agrees that if Landlord shall be an
individual, joint venture, tenancy-in-common, firm, or partnership, general or
limited, there shall be no personal liability on such individual or on the
members of such joint venture, tenancy-in-common, firm or partnership in respect
of any of the covenants or conditions of this Lease; rather, Tenant agrees to
look solely to Landlord's estate and property in the Building (or the proceeds
thereof) for the satisfaction of Tenant's remedies arising out of or related to
this Lease.

          (c) The term "Landlord" as used in this Lease means only the owner, or
the mortgagee in possession, for the time being of the Demised Premises (or the
owner of a lease of the Demised Premises) so that in the event of any sale or
sales of the Land, the Building, or the Demised Premises or of said lease, or in
the event of a lease of the Land, the Building or of the Demised Premises, the
said Landlord shall be and hereby is entirely freed and relieved of all
covenants and obligations of the Landlord hereunder, and it shall be deemed and
construed without further agreement between the parties or their successors-in-
interest, or between the parties and the purchaser, at any such sale, or the
said lessee of the Land, Building or of the Demised Premises, that the purchaser
or the lessee of the same has assumed and agreed to carry out any and all
covenants and obligations of Landlord hereunder.


     30.  Miscellaneous.
          ------------- 

          (a) This Lease contains the entire contract between the parties.  No
representative, agent or employee of Landlord has been authorized to make any
representations or promises with reference to the leasing of the Demised
Premises or to vary, alter or modify the terms hereof.  No additions, changes or
modifications, renewals, or extensions hereof, shall be binding unless reduced
to writing and signed by Landlord and Tenant.

          (b) The terms, conditions, covenants and provisions of this Lease
shall be deemed to be severable.  If any clause or provision herein contained be
adjudged to be invalid or unenforceable by a court of competent jurisdiction or
by operation of any applicable law, it shall not affect the validity of any
other clause or provision herein but such other clauses or provisions shall
remain in full force and effect.

          (c) The paragraph headings in this Lease are for convenience
only and are not to be considered in construing the same.

          (d) If, in connection with obtaining financing for the Building, a
banking, insurance or other recognized institutional lender shall request
reasonable modifications in this Lease as a condition to such financing, Tenant
shall not unreasonably withhold, delay or defer its consent thereto, provided
that (i) such modifications do not in any significant manner increase the
obligations of Tenant hereunder, or affect the leasehold interest created
hereby, or impair the conduct of Tenant's business operations at the Demised
Premises or materially diminish Landlord's responsibilities hereunder; and (ii)
such modifications do not affect the Term, rent, renewal or expansion rights, or
work letter allowances afforded to Tenant hereunder.

          (e) This Lease shall be governed by and construed in accordance with
the laws of the State of New Jersey.

          (f) The parties agree that any litigation arising out of this Lease
shall be venued in the Superior Court of New

                                     - 29 -
<PAGE>
 
Jersey.  Each party waives trial by jury in any action or proceeding arising out
of this Lease.

          (g) Tenant shall not allow the Demised Premises to be encumbered by a
mechanic's lien.  If any mechanic's or material-man's lien is filed against the
Demised Premises, the Building or the Land as a result of any additions,
alterations, repairs, installations, improvements or any other work or act of
Tenant, Landlord shall notify Tenant of same and Tenant shall discharge or bond
same within fifteen (15) days from the date Tenant is notified of the filing of
the lien.  If Tenant shall fail to discharge or bond the lien, Landlord may bond
or pay lien or claim for the account of Tenant without inquiring into the
validity of the lien or claim and Tenant shall reimburse Landlord upon demand.

          (h) Each party represents to the other that the undersigned officer(s)
have been duly authorized to enter into this Lease and that the execution and
consummation of this Lease does not and shall not violate any provision of any
by-laws, certificate of incorporation, agreement, order, judgment, governmental
regulation or any other obligations to which the parties are subject. Upon
execution hereof, Tenant shall deliver a Secretary's certificate evidencing its
authority to execute this Lease.

          (i) Landlord represents that it is the owner in fee, simple of the
Land and the Building and that the title thereto is not subject to any covenant,
restriction or other encumbrance which would preclude the use and occupancy of
the Demised Premises by Tenant for the Permitted Use.

          (j) Whenever Landlord's consent or approval is required under this
Lease, Landlord agrees that such consent shall not be unreasonably withheld or
delayed at such times as Tenant is not in default in the performance of any of
its obligations under this Lease beyond this applicable grace period provided
herein. This subparagraph (j) shall not apply to any provision in this Lease
which expressly permits Landlord to arbitrarily withhold its consent or
approval.

     31.  Hold Over Tenancy.  If Tenant shall hold over after the expiration of
          -----------------
the term of this Lease or any extensions hereof, Tenant shall be deemed to be
occupying the Demised. Premises as a tenant from month-to-month, which tenancy
may be terminated as provided by New Jersey state law. Tenant acknowledges that
holding over beyond the term of this Lease may cause Landlord damages that are
impossible to estimate or quantify for purposes of this Lease. Therefore, during
such tenancy, Landlord and Tenant agree that Tenant shall pay to Landlord one-
hundred fifty percent (150%) of the Fixed Monthly Rent in effect on the
Expiration Date plus all other sums due hereunder, making such payment in
accordance with this Lease. Tenant shall be otherwise bound by all of the terms,
covenants and conditions contained in this Lease.

     32.  Tenant's Expansion Options.
          -------------------------- 

          (a) Tenant is hereby granted the option to lease an additional six
thousand (6,000) square feet of gross rentable area of office space located on
the third floor of the Building and currently occupied by Gale & Wentworth,
Inc.,  which area is identified as Option Space A on the floor plan attached
hereto as Exhibit F, subject to reasonable adjustments in the configuration of
the space as may in the future be agreed upon by the parties, ("Option Space A")
at any time between the second and fourth anniversaries of the Commencement
Date.  In the event that Tenant desires to lease Option Space A, it must give
notice in writing to Landlord of Tenant's intention to lease Option Space A no
earlier than the eighteen (18) month anniversary of the Commencement Date and no
later than the forty-two (42) month anniversary of the

                                     - 30 -
<PAGE>
 
Commencement Date. Such notice shall fix a date for the commencement of the
lease of Option Space A which shall be six (6) months after the date of such
notice. Failure of Tenant to provide Landlord with such notice shall be deemed
to be a termination of Tenant's right to lease Option Space A pursuant to the
terms and provisions of this Paragraph 32(a). If said option is exercised, all
of the terms and conditions of this Lease shall remain in effect for Option
Space A except that: (i) the annual and monthly Fixed Rent shall be increased
based upon the increase in the gross floor area of the Demised Premises
resulting from the addition of Option Space A; (ii) Landlord shall provide a
period of rent abatement equal to nine (9) months Fixed Rent (as to Option Space
A only) multiplied by a fraction the numerator of which is the number of years
remaining in the Term on the date on which the lease of Option Space A commences
and the denominator of which is the number twelve (12); and (iii) Landlord shall
provide a construction allowance equal to Thirty-one Dollars ($31) per square
foot of office space in Option Space A if Tenant's notice is given between the
eighteen (18) month and thirty (30) month anniversaries of the Commencement Date
and Twenty-nine Dollars ($29) per square foot of office space in Option Space A
if such notice is given on or after the thirty (30) month anniversary of the
Commencement Date. At such time as the commencement date for Option Space A
begins, Landlord and Tenant shall enter into a separate amendment to this Lease
appropriately incorporating Option Space A into this Lease, including, without
limitation, a recomputation of Tenant's Proportionate Share.

     (b) At any time after November 30, 1995, contingent upon the release or
termination of the expansion rights of Merrill Lynch, Pierce, Fenner & Smith
Incorporated, Tenant shall be granted the option to lease an additional five
thousand (5,000) square feet of gross rentable area of office space located on
the third floor of the Building, which area is identified as Option Space B on
the floor plan attached hereto as Exhibit G ("Option Space B"). In the event the
Tenant desires to lease Option Space B, it must give notice in writing to
Landlord of Tenant's intention to lease Option Space B after November 30, 1995.
Such notice shall fix a date for the commencement of the lease of Option Space B
which shall be six (6) months after the date of such notice. Failure of Tenant
to provide Landlord with such notice during the Term shall be deemed to be a
termination of Tenant's right to lease Option Space B pursuant to the terms and
provisions of this Paragraph 32(b). If said option is exercised, all of the
terms and conditions of this Lease shall remain in effect for Option Space B
except that: (i) the annual and monthly Fixed Rent shall be increased based upon
the increase in the gross floor area of the Demised Premises resulting from the
addition of Option Space B; (ii) Landlord provide a period of rent abatement
equal to nine (9) months Fixed Rent (as to Option Space B only) multiplied by a
fraction the numerator of which is the number of years remaining in the Term on
the date on which the lease of Option Space A commences and the denominator of
which is the number twelve (12); and (iii) Landlord shall not be required to
provide the same per square foot rate construction allowance as set forth herein
but shall provide instead a work letter allowance of Thirty-one Dollars ($31.00)
per square foot of office space in Option Space B multiplied by a fraction the
numerator of which is the number of years remaining in the Term on the date on
which the lease of Option Space B commences and the denominator of which is the
number twelve (12). At such time as the commencement date for Option Space B
begins, Landlord and Tenant shall enter into a separate amendment to this Lease
appropriately incorporating Option Space B into this Lease, including, without
limitation, a recomputation of Tenant's Proportionate Share.

     (c) It shall be a condition of Tenant's right to exercise the options set
forth in Paragraphs 32(a) and 32(b) that at the time of the exercise of said
option that Tenant shall not be in default under this Lease beyond any
applicable grace period.

     33.  Right of First Offer.
          -------------------- 

          (a) If at any time during the Term (exclusive of any Renewal Term),
Landlord decides to lease space on the third floor of the Building ("Third Floor
Offer Space"), then Landlord shall, before deciding to so lease the space,
provide written notice to Tenant enclosing an offer of the terms and conditions
upon which Landlord would be willing to lease the Third Floor Offer Space, which
notice shall be accompanied by a floor plan of the Third Floor Offer Space. The
fixed rent specified in such notice shall be the greater of (i) the prevailing
fixed rent then being offered to tenants leasing similar space in the Building,
or (ii) the Fixed Rent payable by Tenant hereunder on the date of the notice.
Tenant shall then have a period of ten (10) days after receipt of the notice
containing the offer within which to accept such offer in writing, by notice
given in accordance with Paragraph 18 of this Lease, upon the terms and
conditions specified therein. In the event Tenant shall accept Landlord's offer,
then Landlord and Tenant shall enter into an amendment to this Lease upon the
terms and conditions specified in Landlord's notice to Tenant. In the event
Tenant shall fail to respond to Landlord during such ten (10) day period, then
Landlord shall thereafter be free to lease the First Offer Space to any third
party.

          (b) If at any time during the Term, including any Renewal Term, any
storage space located in the lower level of the Building becomes available,
Landlord shall, prior to leasing such available storage space, provide written
notice to Tenant enclosing an offer of the terms and conditions upon which
Landlord would be willing to lease the storage space. Tenant shall then have a
period of ten (10) days after receipt of the notice containing the offer within
which to accept such offer in writing, by notice given in accordance with
Paragraph 18 of this Lease, upon the terms and conditions specified herein. In
the event that Tenant accepts Landlord's offer, then Landlord and Tenant shall
enter into an amendment of this Lease incorporating the storage space on the
terms and conditions specified in Landlord's notice to Tenant. In the event that
Tenant fails to respond to Landlord during such ten (10) day period, then
Landlord shall thereafter be free to lease the storage space to any third party.

          (c) It shall be a condition of Tenant's right to exercise its right of
first offer for the Third Floor Offer Space or the storage space as set forth in
this Paragraph 33, that, at the time of such exercise Tenant shall not be in

     34.  Satellite Dish Antenna.  Tenant shall have the right, at its sole
          ----------------------                                         
cost and expense, to install and maintain on the Building's roof the equipment
and satellite dish antenna (or similar transmitting device) required for
Tenant's communications and data transmission network (the "Antenna"). Tenant
shall be solely responsible for obtaining, with Landlord's reasonable
cooperation, if necessary (but at no cost to Landlord), any and all governmental
approvals and permits, including, without limitation, any FCC permit and any
amendment of the Building's site plan approval, which may be required in
connection with the installation and use of the Antenna. The Antenna shall be
located in an area mutually acceptable to both Tenant and Landlord. Landlord
shall have the right to relocate the Antenna, at its sole cost and expense, at
any time and from time to time during the Term, provided such relocation does
not unreasonably interfere with Tenant's business at the Demised Premises and
further provided that Landlord shall provide Tenant with reasonable prior notice
of said relocation and Landlord shall cooperate with Tenant in effectuating said
relocation. Tenant shall not have the exclusive right to use the Building roof
for its Antenna, but rather, shall be subject to the right of Landlord to use
the roof or to permit other tenants of the Building to use the roof for their
needs. In the event that Land-

lord permits any other tenant to use the roof for equipment similar to the
Antenna, such other tenant's use shall not unreasonably interfere with Tenant's
Antenna. Tenant shall not be permitted to terminate this Lease or be entitled to
a reduction or abatement of the rent due and payable under this Lease in the
event that Tenant is unable to obtain the necessary permits and approvals to
install the Antenna or if conditions beyond Landlord's control interfere with
Tenant's use of the Antenna. Tenant shall be permitted access to the Building
roof and to the risers and conduits within the Building for purposes of
installing and maintaining the Antenna, which access shall not unreasonably
interfere with any other tenant's use and enjoyment of the Building. Tenant
shall pay the cost of any Building modifications or improvements required to
accommodate the Antenna. Tenant hereby indemnifies and holds Landlord harmless
from and against any and all claims, damages, liabilities, costs and expenses
(including without limitation attorneys fees and litigation costs) arising out
of Tenant's construction, installation, replacement, maintenance and general use
of the Antenna. Tenant acknowledges that Landlord has made no representations or
warranties to Tenant that the Antenna is permitted under applicable zoning
ordinances. Tenant shall comply with any such ordinances, at its sole cost and
expense. Tenant's use of the roof space shall not require a separate or
additional rent payment by Tenant.

     35.  Cafeteria.  The Landlord covenants that so long as Tenant or an
          ---------

for said cafeteria, or for a brief period of time, not to exceed one hundred
twenty (120) days, while said facility is being repaired or restored after

or air conditioning equipment, or any other energy systems installed in the
Demised Premises, entitle the purchaser thereof to any rebate of the cost of
purchase, Landlord shall assign to Tenant all of its interest in such rebate.
Landlord shall cooperate with Tenant at no expense to Landlord to enable Tenant

                                     - 33 -

                          Sammis Morristown Associates

                          Schein Pharmaceutical, Inc.


     Section 1.1.  The provisions of this Exhibit shall have the same force and
effect as if this Exhibit were a numbered Article of the Lease.

     Section 2.1. (a) Landlord and Tenant have approved and do hereby
incorporate by reference herein as Exhibit B-1 work letter specifications and
preliminary plans for the construction of the Demised Premises (the "Preliminary
Plans"). The parties acknowledge that the Preliminary Plans were prepared based
upon a Demised Premises of 38,180 square feet of gross floor area of office
space. In finalizing the Preliminary Plans, the gross floor area of the Demised
Premises will be increased to 40,899 square feet and, as a result, the
quantities and allowances set forth in Exhibit B-1 shall be increased by 7.12%
(except for those expressed as an amount per square foot). Subject to the
provisions of this, Lease, Landlord agrees, to construct the Demised Premises in
accordance with the Final Plans (as hereinafter defined) finalized from the
Preliminary Plans, which construction shall be completed in a good and
workmanlike manner and in compliance with all applicable laws and regulations.
The work, fixtures, equipment and other improvements depicted on the Final Plans
are referred to in this Lease as the "Tenant Improvements". Tenant shall pay to
Landlord the sum of One Hundred Seven Thousand Dollars ($107,000) toward the
cost of constructing the Tenant Improvements ("Tenant's Construction Cost");
otherwise, Landlord shall complete the construction at Landlord's sole cost and
expense. Tenant's Construction Cost shall be paid to Landlord on the sooner of
(i) the date on which Tenant takes occupancy of the Demised Premises or (ii) the
date which is five (5) days of the issuance of a temporary or permanent
Certificate of Occupancy for the Demised Premises.

                  (b) Landlord shall pay the cost of preparing the Preliminary
Plans and the Final Plans up to a maximum of Four Dollars and Fifty Cents
($4.50) per useable square foot as provided in Exhibit B-1. Any revisions to the
Final Plans shall be at Tenant's sole cost and expense thereto.

     Section 3.1. (a) In order to finalize the Preliminary Plans or in the event
that Tenant desires any change in the Preliminary Plans before finalization,
Tenant shall submit to Landlord, proposed final plans setting forth the
finalization of the Preliminary Plans, including any proposed finalization by
April 12, 1993. Within two (2) business days after receipt of any proposed
change to the Preliminary Plans, Landlord shall approve or reject same and if
rejecting same shall state the reasons for such rejection. Landlord agrees not
to unreasonably withhold its approval to any changes or to the proposed final
plans. If the proposed final plans included any changes from the Preliminary
Plans, upon the granting of any approval, Landlord shall notify Tenant of the
amount, if any, of the charge to Tenant arising therefrom (which charge shall be
determined after deducting any savings attributable to said change and which
charge shall be paid by Tenant to Landlord within ten (10) days after the
issuance of a temporary or permanent certificate of occupancy for the Demised
Premises). In the event of a rejection by Landlord of any proposed final plans,
Tenant may make changes to the proposed final plans and resubmit them pursuant
hereto. Upon receiving Landlord's approval to any proposed final plans, such
plans shall become the Final Plans (the "Final Plans") hereunder. No plans
submitted to Landlord shall be considered to be Final Plans unless they are

                                      B-1
<PAGE>
 
submitted to Landlord signed and sealed and in proper and sufficient form for
Landlord to obtain all necessary permits and approvals to construct the Demised
Premises in accordance with such Final Plans.  Any delay in the completion of
the Demised Premises caused by the Final Plans being delivered to Landlord,
fully approved and in the proper form as set forth herein, later than May 5,
1993 shall be a Tenant Delay (as hereinafter defined).

          (b) In the event that Tenant desires any change in the Final Plans,
Tenant shall submit to Landlord revised final plans setting forth the proposed
change and instructing Landlord whether to cease work or cease any segment of
work while the change is approved (in which case the delay shall be a Tenant
Delay as hereinafter defined) or whether Landlord should continue constructing
the Demised Premises in accordance with the Final Plans notwithstanding the
proposed change thereto. In the event that no such instructions are given,
Landlord shall continue constructing the Demised Premises in accordance with the
Final Plans without regard to the proposed changes thereto. Within two (2)
business days after receipt of any proposed change in the Final Plans from
Tenant, Landlord shall approve or reject same and, if rejecting same, shall
state the reasons for such rejection. Landlord agrees not to unreasonably
withhold its approval to any such change. If Landlord has stopped work, or some
segment thereof, at Tenant's request, Landlord shall resume work, or some
segment thereof, at Tenant's written instructions from Tenant authorizing the
recommencement of such work. Upon the granting of any approval, Landlord shall
notify Tenant of the amount, if any, of the charge to Tenant arising therefrom
(which charge shall be determined after deducting any savings attributable to
said change and which charge shall be paid by Tenant to Landlord within thirty
(30) days after the issuance of a temporary or permanent certificate of
occupancy for the Demised Premises) and Landlord's estimate of the delay in
completion that will be caused by such proposed revision to the Final Plans. In
the event of a rejection by Landlord of a proposed revision, Tenant may make
changes to the proposed revision and resubmit it pursuant hereto. Upon receiving
Landlord's approval to any revision, Tenant shall, as soon thereafter as
practicable, but in no event in excess of two (2) business days, and
understanding that any delay in responding may cause delays in completion
substantially greater than the estimate given by landlord, authorize the work
that Tenant desires by approving in writing the work and the cost thereof, and
submitting to Landlord signed and sealed revised final plans sufficient for
Landlord to obtain all necessary permits and approvals to construct the Demised
Premises in accordance with such revised final plans. Upon the submission of
such revised final plans, such revised final plans shall become the Final Plans
hereunder. Any delay in completion caused by the revision to the Final Plans,
whether greater or less than Landlord's estimate, shall be a Tenant Delay (as
hereinafter defined).

          (c) Any reduction in the cost of constructing the Tenant Improvements
resulting from changes to the Preliminary or Final Plans shall result in a
dollar for dollar reduction in Tenant's Construction Cost; provided, however,
that in no event shall Landlord be required to rebate any funds to Tenant due to
cost reductions in excess of Tenant's Construction Cost.

     Section 3.2. If (a) a delay shall occur in the completion of the Demised
Premises in accordance with the Final Plans or any revised Final Plans by the
Landlord as the result of any act of or by Tenant or any of its employees,
agents or contractors which materially interferes with the completion of the
Tenant Improvements, including, without limitation, (i) any delay in delivering
the Final Plans to Landlord in the form and on the date required by Section
3.1(a) hereof, (ii) any direction by Tenant that the Landlord delay proceeding
with the work or any segment of the work in anticipation of a possible revision
to the Final Plans by Tenant or for any other reason, (iii) any revision to the
Final

                                      B-2
<PAGE>
 
Plans authorized by Tenant, or (iv) any additional time required for the
completion by Landlord of its work because of the inclusion therein at Tenant's
request of any item of work not included in the Final Plans, or (v) any other
act or omission of Tenant, its agents, employees or contractors (any of such
events being a "Tenant Delay"), then (b) the Commencement Date shall (even
though no Certificate of Occupancy has been issued or the Demised Premises has
not been completed) be deemed to be one day earlier than provided for in
Paragraph 4(b) of the Lease for each day of such Tenant Delay. Landlord shall
notify Tenant of any event or occurrence which constitutes a Tenant Delay within
five (5) days of such event or occurrence. If Landlord fails to give such
notice, Landlord shall be deemed to have waived such Tenant Delay for the period
prior to the date which is five (5) days prior to the giving of such notice. The
extent of any Tenant Delay shall be determined in the following manner: Landlord
shall notify Tenant of a Tenant Delay and the estimated length of the Tenant
Delay involved as soon as practicable after the information necessary to
estimate such Tenant Delay is available (which notice shall include the basis
for the Landlord's estimate) and, as Landlord obtains the information to
calculate the actual Tenant Delay, Landlord shall so notify Tenant, providing it
with the basis used in calculating such Tenant Delay. In the event of a dispute
concerning the length of any Tenant Delay, Landlord's calculation shall be used
and the Commencement Date shall occur in accordance therewith, provided,
however, that Tenant shall retain its right to challenge Landlord's calculation
of the length of the Tenant Delay, and such dispute shall be submitted to
arbitration by the American Arbitration Association or such other arbitrator as
may be selected by mutual agreement of the parties, such arbitration to be
conducted in accordance with the rules of the American Arbitration Association
pertaining to commercial arbitration.

                                   --------

        A.  Landlord is the owner of that certain land (the "Land") located in
the Borough of Florham Park, County of Morris, State of New Jersey and more
particularly described in Exhibit A attached hereto and by this reference made a
                          ---------                                             
part hereof.  As used herein, the term "Property" shall refer to the Land
together with all improvements located thereon.

        B.  Landlord and Lender previously have entered into that certain
Construction Loan Agreement dated as of June 9, 1989, as amended pursuant to
that certain Modification Agreement dated July 26, 1989 by and between Landlord
and Lender and as further amended by that certain Second Modification Agreement
(the "Second Modification") dated January 10, 1990, by and between Landlord and
Lender (as modified, the "Loan Agreement"), pursuant to which Lender agreed to
lend and Landlord agreed to borrow up to Ninety Million Dollars ($90,000,000)
(the "Loan") upon the terms and conditions contained therein.

        C.  The Loan is evidenced by that certain Promissory Note dated as of
June 9, 1989 (the "Note"), executed by Landlord, as maker, and payable to the
order of Lender, as holder, in the principal amount of Ninety Million Dollars
($90,000,000).

        D.  The Note is secured by, among other things, a Mortgage dated June 9,
1989, executed by Landlord, as mortgagor in favor of Lender as mortgagee, and
recorded on June 14, 1989, in the Office of the Clerk of Morris County, New
Jersey, in Mortgage Book 3016, Page 0241 as modified by that certain Mortgage
Modification Agreement dated July 26, 1989, by and between Landlord, as

mortgagor and Lender, as mortgagee, and recorded on August 1, 1989, in the
Office of the Clerk of Morris County, New Jersey in Mortgage Book 3066, Page
0001 and as further amended by that certain Second Mortgage Modification
Agreement dated January 10, 1990 by and between Landlord, as mortgagor, and
Lender, as mortgagee and recorded on March 6, 1990, in the Office of the Clerk
of Morris County, New Jersey, in Mortgage Book 3273, Page 0128 (as amended, the
"Mortgage").

          E.  The Note is also secured by, among other things, that certain
Assignment of Rents, Leases, Income and Profits dated as of June 9, 1989, by
Landlord, as assignor, in favor of Lender, as assignee, recorded on June 14,
1989, in the Office of the Clerk of Morris County, New Jersey in Mortgage Book
3016, Page 0276, as modified by that certain Assignment of Rents Modification
Agreement dated as of July 26, 1989, by and between Landlord, as assignor, and
Lender, as assignee and recorded on August 1, 1989, in the Office of the Clerk
of Morris County, New Jersey in Mortgage Book 3066, Page 0015 and as further
amended by the Second Modification (as modified,  the "Assignment of Rents").
The Mortgage and the Assignment of Rents together with any and all other
documents now or hereafter securing the Note, are collectively referred to
herein as the "Security Documents."

          F.  Tenant and Landlord have entered into or are about to enter into
that certain lease dated as of April   , 1993 by and between Tenant and Landlord
(the "Lease") pursuant to which Landlord leased to Tenant a portion of the
improvements located on the Land and more particularly described in the Lease
(the "Premises").

          G.  Upon receipt of a nondisturbance agreement, Tenant has obligated
itself under the terms of the Lease to execute any document necessary or
appropriate to subordinate the Lease to the Security Documents.

          H.  Landlord has obligated itself under the terms of the Lease to
furnish Tenant with an undertaking by Lender as set forth herein and Lender is
willing to provide such undertaking on the terms and conditions set forth
herein.

          NOW, THEREFORE, in consideration of the foregoing recitals, which are
incorporated herein by this reference, and for other valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
hereby covenant and agree as follows:

          1.  Landlord does hereby grant, transfer and assign to Lender the
Lease together with all rents and other sums payable under the Lease; provided,
however, that until written demand is made by Lender to Tenant, all rents and
other sums payable under the Lease shall be paid to Landlord, but only as they
become payable. Upon receipt of written notice by Lender to Tenant pursuant to
Paragraph 18 hereof, Tenant shall thereafter pay all rents and other sums
payable under the Lease to Lender. Landlord agrees to indemnify, defend and hold
tenant harmless from and against any and all loss, claim, damage or liability
arising out of Tenant's compliance with such notice.

          2.  Subject to the provisions of this Agreement, the Security
Documents (and each of them) and all supplements, amendments, and modifications
thereto and all renewals, replacements or extensions thereof, shall
unconditionally be and remain at all times a lien or charge on the Property
prior and superior to the Lease, to the leasehold estate created thereby and to
all rights and privileges of Tenant thereunder, and the Lease, the leasehold
estate created thereby, together with all rights and privileges of Tenant
thereunder; is hereby unconditionally subjected, and made subordinate, to the
lien or charge of the Security Documents (and each of them) in favor of Lender.
Tenant declares, agrees and acknowledges that Lender, in making disbursements
pursuant to the

                                      E-2
<PAGE>
 
Loan Documents (as defined in the Mortgage), is under no obligation or duty to,
nor has Lender represented that it will, see to the application of such proceeds
by the person or persons to whom Lender disburses such proceeds, and any
application or use of such proceeds for purposes other than those provided for
in such agreement or agreements shall not defeat the subordination herein made
in whole or in part.

          3.  So long as Tenant is not in default in performance of the terms,
provisions and conditions contained in the Lease beyond any notice and cure
period provided in the Lease, and so long as Tenant observes the provisions of
Paragraph 4 of this Agreement:

              (a)   Tenant shall not be named or joined in any foreclosure or
     other proceeding to enforce the Mortgage unless such joinder be required by
     law in order to perfect such foreclosure or other proceeding;

              (b)   enforcement of the Mortgage shall not terminate the Lease or
     disturb Tenant's possession and use of the Premises or affect any of
     Tenant's other rights, options and privileges under the Lease; and

              (c)   the leasehold estate granted by the Lease shall not be
     affected in any manner by any foreclosure or other proceeding instituted or
     action taken under or in connection with the Mortgage or in case Lender
     takes possession of the Premises pursuant to any provision of the Mortgage,
     except that a transferee (including, but not limited to, Lender) of the
     interest of Landlord as a result of such foreclosure or other proceeding
     and such transferee's successors and assigns (such transferee, its
     successors and assigns, including, but not limited to, Lender, being
     hereinafter referred to as "Purchaser") shall not:

                    (i)    be liable for any damages or other relief
          attributable to any act or omission of any prior landlord under the
          Lease (including, without limitation, Landlord);

                    (ii)   be liable for any damages or other relief
          attributable to any latent or patent defects in construction unless
          and only to the extent such defects are the result of such Purchaser's
          negligent act or omission, provided, however, this Paragraph 3(c)(ii)
          shall not be deemed a waiver or relinquishment by Tenant of any right
          or cause of action Tenant may have against any contractor, architect
          or other party (other than a Purchaser) for such defect, and provided,
          further, any such action against Landlord shall be expressly subject
          to Paragraph 2 hereof;

                    (iii)  be liable for any consequential damages attributable
          to any act or omission of said Purchaser;

                    (iv)   be liable for any damages or other relief
          attributable to any breach by any prior landlord (including Landlord)
          under the Lease of any representation or warranty contained in the
          Lease;

                    (v)    be subject to any offsets or defenses not
          specifically provided for in the Lease and which Tenant may have
          against any prior landlord under the Lease; and

                    (vi)   be bound by any prepayment by Tenant of more than one
          month's installment of rent or for any security deposit not actually
          delivered to Purchaser, or by any modification of or amendment to the
          Lease, unless such prepayment, amendment or modification shall have

                                      E-3
<PAGE>
 
          been approved in writing by Lender or by any subsequent mortgagee
          under the Mortgage, which approval shall not be unreasonably withheld
          or delayed.

          4.  If the interest of Landlord in the Property shall be transferred
by reason of any foreclosure or other proceeding for enforcement of the Mortgage
or by deed in lieu thereof, the Lease shall continue in full force and effect as
a direct lease between Purchaser and Tenant, and Tenant shall attorn to
Purchaser, including Lender if it be Purchaser, as the landlord under the Lease,
and Purchaser shall assume Landlord's obligations under the Lease for the
balance of the term then remaining, including any renewal options; the
provisions of this sentence shall be effective and self-operative without the
execution of any further instruments upon Purchaser's succeeding to the interest
of the landlord under the Lease.  Tenant hereby waives any right to exercise any
purchase option contained in the Lease in the event of any transfer to
Purchaser.  Landlord hereby agrees to give Tenant prompt written notice of any
foreclosure or other proceeding for the enforcement of the Mortgage; provided
however, any failure by Landlord to give such notice shall in no way affect the
rights of any Purchaser.

          5.  In the event of default by Landlord in its performance of the
terms, provisions and conditions of the Note or of any Security Document, Tenant
agrees to recognize the assignment of the Lease made by Landlord to Lender
hereunder and pursuant to the Assignment of Rents and shall pay to Lender, as
assignee, the rents under the Lease, but only those which are due or which come
due to Landlord under the terms of the Lease at or after the time Lender gives
Tenant notice that Landlord is in default under the terms of the Note or
Security Documents.  Such payments of rents to Lender by Tenant by reason of
said assignment and of Landlord's default shall continue until the first to
occur of the following:

              (a) No further rent is due or payable under the Lease;

              (b) Lender gives Tenant notice that the default of Landlord
       under the note or Security Documents has been cured and instructs
       Tenant that the rents shall thereafter be payable to Landlord; or

              (c) The lien of the Mortgage has been foreclosed and Purchaser
       gives Tenant notice of such foreclosure. Purchaser shall thereupon
       succeed to the interests of Landlord under the Lease as provided in
       Paragraphs 2, 3 and 4 hereof, after which time the rents and other
       benefits of Landlord under the Lease shall be payable to Purchaser as
       the owner thereof.

          6.  In complying with the provisions of Paragraph 5 hereof, Tenant
shall be entitled to rely solely upon the notices given by Lender which are
referred to in Paragraph 5 hereof and Landlord agrees to indemnify and hold
Tenant harmless from and against any and all loss, claim, damage, or liability
arising out of Tenant's compliance with such notice. Tenant shall be entitled
to full credit under the Lease for any rents paid to Lender in accordance with
the provisions of Paragraph 5 hereof to the same extent as if such rents were
paid directly to Landlord.   Any dispute between Lender (or other Purchaser) and
Landlord as to the existence or continuance of a default by Landlord under the
terms of the Note or Security Documents, or with respect to the extent or nature
of such default, or with respect to foreclosure of the Mortgage by Lender, shall
be dealt with and adjusted solely between Lender (or other Purchaser) and
Landlord, and Tenant shall not be made a party thereto (unless required by law).

          7.  Nothing in this Agreement shall be deemed to be or construed to be
an agreement by Lender to perform any covenant of the Landlord as landlord under
the Lease unless and until it

                                      E-4
<PAGE>
 
obtains title to the Property by judicial foreclosure or deed in lieu thereof or
obtains possession of the Property pursuant to the terms of the Mortgage.

         8.  Tenant agrees that during the term of the Lease, without Lender's
prior written consent, Tenant will not:

              (a) pay any rent or additional rent more than one month in advance
     to any landlord (including, but not limited to, Landlord);

              (b) cancel, terminate or surrender the Lease, except at the normal
     expiration of the Lease term or otherwise in accordance with the terms and
     conditions of the Lease; or

              (c) enter into any material amendment or modification of the
     Lease, provided, however, no Purchaser shall be bound by any amendment or
     modification of the Lease which has not been approved by Lender in writing.

         9.   Landlord, Tenant and Lender agree that unless Lender shall
otherwise consent in writing, Landlord's estate in and to the Property and the
leasehold estate created by the Lease shall not merge but shall remain separate
and distinct, notwithstanding the union of said estates either in Landlord or
Tenant or any third, party by purchase, assignment or otherwise.

         10.  Tenant, from and after the date hereof, shall send a copy of any
notice of default under the Lease to Lender at the same time such notice is sent
to Landlord under the Lease.  Such notices shall be delivered to Lender in the
manner and at the addresses set forth in Paragraph 18 hereof.

         11.  Anything herein or in the Lease to the contrary notwithstanding,
in the event that any Purchaser shall acquire title to the Property, said
Purchaser shall have no obligation, nor incur any liability, beyond the then
interest, if any, of said Purchaser in the Property and Tenant shall look
exclusively to such interest of said Purchaser, if any, in the Property for the
payment and discharge of any obligations imposed upon said Purchaser hereunder
or under the Lease, and said Purchaser is hereby released and relieved of any
liability hereunder and under the Lease beyond any such interest in the
Property.  As regards said Purchaser, Tenant shall look solely to the estate or
interest owned by said Purchaser in the Property and Tenant will not collect or
attempt to collect any such judgment out of any other assets of said Purchaser.
By executing this Agreement, Landlord specifically acknowledges and agrees that
nothing contained in this Paragraph 11 shall impair, limit, affect, lessen,
abrogate or otherwise modify the obligations of Landlord to Tenant under the
lease.

         12.  Tenant and Landlord each hereby certifies that as of the date
hereof, to the best of its respective knowledge, there are no defaults on the
part of the other party under the Lease, that the Lease is a complete statement
of the agreement of the parties thereto with respect to the leasing of the
Premises, that the Lease is in full force and effect, and that all conditions to
the effectiveness or continuing effectiveness thereof required to be satisfied
as of the date hereof have been satisfied.

         13.  This Agreement shall be the whole and only agreement with regard
to the subjection and subordination of the Lease and the leasehold estate
created thereby, together with all rights and privileges of Tenant thereunder,
to the lien or charge of the Security Documents (and each of them) and shall
supersede and cancel, but only insofar as would affect the priority between the
Lease and the Security Documents (and each of them), any prior agreements as to
such subjection or subordination, including, but not limited to, those
provisions contained in the Lease which provide for the subjection or
subordination of the Lease and the

                                      E-5
<PAGE>
 
leasehold estate created thereby to a deed or deeds of trust or to a mortgage or
mortgages.

          14.  This Agreement may be executed in any number of counterparts,
each of which when so executed and delivered shall be deemed to be an original
and all of which counterparts taken together shall constitute but one and the
same instrument. Signature and acknowledgement pages may be detached from the
counterparts and attached to a single copy of this Agreement to physically form
one document, which may be recorded.

          15.  This Agreement may not be modified orally or in any manner other
than by an agreement in writing signed by the parties hereto or their respective
successors in interest.  This Agreement shall inure to the benefit of and be
binding upon the parties hereto and their respective successors and assigns.

          16.  In the event any legal action or proceeding is commenced to
interpret or enforce the terms of, or obligations arising out of, this
Agreement, or to recover damages for the breach thereof,  the party prevailing
in any such action or proceeding shall be entitled to recover from the non-
prevailing party all reasonable attorneys' fees, costs and expenses incurred by
the prevailing party.

          17.  The interpretation, validity and enforcement of this Agreement
shall be governed by and construed under the laws of the State of New Jersey.

          18.  All notices and other communications to be made hereunder to the
parties hereto shall be in writing (at the addresses set forth below) and shall
be given by any of the following means:  (a) personal service; (b) electronic
communication, whether by telex, telegram or telecopying (if confirmed in
writing sent by registered or certified first class mail, return receipt
requested); or (c) registered or certified first class mail, return receipt
requested.  Such addresses may be changed by notice to the other parties given
in the same manner as provided above.   Any notice or other communication sent
pursuant to subsection (a) or (b) hereof shall be deemed received upon such
personal service or upon dispatch by electronic means, and, if sent pursuant to
subsection (c), shall be deemed received five (5) days following deposit in the
mail.

                      FIRST AMENDMENT TO LEASE AGREEMENT


        THIS FIRST AMENDMENT TO LEASE AGREEMENT is made this 26th day of
 October, 1994 between VALLEY NATIONAL BANK, as subtrustee ("Landlord"), having
 an office address c/o Gale & Wentworth, 100 Campus Drive, Florham Park, New
 Jersey 07932 and SCHEIN PHARMACEUTICAL, INC., a Delaware corporation
 ("Tenant"), having an address of 100 Campus Drive, Florham Park, New Jersey
 07932.

                                P R E A M B L E
                                - - - - - - - -

        A. By Lease Agreement dated April 16, 1993 (the "Lease"), Sammis
Morristown Associates, Landlord's predecessor in title, leased to Tenant and
Tenant leased from said party certain premises therein described on the third
floor of the office building at 100 Campus Drive, Florham Park, New Jersey.

        B.  The parties desire to amend the Lease to include the demise of
additional premises on the first floor of the Building.

        C.  All terms not specifically defined herein shall have the meanings
given to them in the Lease.

        NOW, THEREFORE, in consideration of the foregoing, the parties agree
that the Lease is hereby amended as hereafter provided, effective as of the
"Effective Date", as defined below:

          1.  Upon the occurrence of the Effective Date, the Demised Premises
shall be increased to include the portion of the first floor of the Building
outlined on the floor plan which is annexed hereto as Exhibit A-3 (the
"Additional Premises").  The gross rentable area of the Additional Premises is
9,832 square feet.

          2.  The  Term  with  respect  to  the  Additional Premises shall be
coextensive with the Term with respect to the remainder of the Demised Premises.
The parties confirm and agree that the Expiration Date is August 31, 2005.
<PAGE>
 
          3.  Subject to the Rental Abatement described below, the Fixed Rent
with respect to the Additional Premises shall be $20. per square foot of gross
rentable area of office space per annum, i.e., $196,640., payable in equal
monthly installments of $16,386.67, from the Effective Date through August 18,
1999 (the sixth (6th) anniversary of the Commencement Date).  commencing August
19, 1999 and throughout the remainder of the Term, the Fixed Rent with respect
to the Additional Premises shall be $23. per square foot of gross rentable area
of office space per annum, i.e., $226,136., payable in equal monthly
installments of $18,844.67. Therefore, as of the Effective Date, the Fixed Rent
for the entire Demised Premises shall be $1,219,115. per annum, payable in equal
monthly installments of $101,592.91, through August 18,  1999. Commencing August
19, 1999 and for the remainder of the Term, the Fixed Rent for the entire
Demised Premises shall be $1,361,083.25 per annum, payable in equal monthly
installments of $113,423.60.

          4.  Tenant's Proportionate Share with respect to the Additional
Premises  is two and  76/100 percent  (2.76%). Tenant's Proportionate Share with
respect to the entire Demised Premises shall be fourteen and 25/100 percent
(14.25%).


            5.  With respect to parking,  Tenant shall be entitled to thirty-
nine (39) additional Non-Exclusive Spaces.


            6. Notwithstanding the foregoing provisions, Tenant shall not be
required to pay to Landlord the Monthly Fixed Rent with respect to the
Additional Premises attributable to the second (2d) through the fifth (5th)
months after the Effective Date, i.e., February through May, 1995.


          7.A.  Landlord agrees to fit up the Additional Premises in accordance
with plans and specifications prepared by the architectural firm of Knoll Roslyn
Associates, Inc., after consultation with and approval thereof by both Landlord
and Tenant (the "Tenant Improvements").  Each party agrees that it will not
unreasonably withhold its approval of the plans and specifications.


                                      -2-
<PAGE>
 
The work to be performed shall be generally consistent with the character and
quality of the existing improvements in the Demised Premises.  Tenant shall be
responsible for the Construction Cost, as hereafter defined, of the Tenant
Improvements, against which Tenant shall be entitled to an allowance of
$260,548. (the "Tenant Allowance").  The difference between the Construction
Cost and the Tenant Allowance is hereafter called the "Tenant's Finish Cost."
Tenant's Finish Cost shall be payable to Landlord within thirty (30)  days
after  the  substantial  completion  of  the  Tenant Improvements pursuant to
subparagraph C, below.  The failure of Tenant to pay Tenant's Finish Cost when
due shall have the same consequences as a failure of Tenant to pay Fixed Rent
when due. Construction Cost as defined herein shall be the actual cost of the
construction of the Tenant Improvements in accordance with the approved plans
and specifications, plus four percent (4%) of such actual cost as profit to
Landlord and six percent (6%) of such actual cost as a payment to Landlord to
compensate Landlord for its overhead costs. Construction Cost shall only include
the following out-of-pocket soft costs to Landlord:  permits, blueprints,
cleanup, dumpsters  job site supervision, overnight delivery charges,
architectural fees and temporary protection.  Construction Cost shall include
the fees of Knoll Roslyn Associates, Inc. paid by Tenant for space planning and
other architectural services with respect to the Additional Premises.
Construction Cost shall not include the fees of Landlord's architect Mancini 
Duffy, which fees are the sole responsibility of Landlord.   Tenant shall not be
entitled to any portion of the Tenant Allowance not utilized for construction of
leasehold improvements by Tenant in the Building within one year after the
Effective Date.  Tenant shall be allowed access to the Additional Premises prior
to the Effective Date for the purpose of furniture erection and fixture and
equipment installation, so long as Tenant and its agents and contractors do not
interfere with the performance of the Tenant Improvements by Landlord.


                                      -3-
<PAGE>
 
          B. The plans and specifications for the Tenant Improvements shall be
prepared giving effect to the outline specifications contained in Exhibit B-l of
the Leased except where any such specification is inconsistent with the express
provisions of this Amendment.


          C. The Effective Date shall be the later of January  1,  1995  and the
date  of completion of  the Tenant Improvements as  evidenced by the  issuance
of any necessary certificate of occupancy from the Borough of Florham Park.  If
such certificate is not issued by January 1, 1995, the Effective Date shall be
extended until the certificate is issued, unless the delay constitutes a Tenant
Delay as defined in Exhibit B to the Lease. If the Effective Date is delayed as
aforesaid, all corresponding dates of the Lease shall be extended for an
equivalent time, with the exception of the Expiration Date.    Notwithstanding
the foregoing, if the Effective Date has not occurred by June 30, 1995 and the
delay is not attributable to a Tenant Delay or to a situation beyond Landlord's
reasonable control, Tenant shall have the right to terminate this First
Amendment by notice to Landlord whereupon this First Amendment shall be null and
void, but the Lease shall otherwise remain in effect.  Landlord shall be deemed
to  have  substantially  completed  the  Tenant  Improvements notwithstanding
that  minor  or  insubstantial  details  of construction, mechanical adjustment
or decoration remain to be performed within the Additional Premises or any part
thereof, the noncompletion of which does not materially interfere with Tenant's
use of the Additional Premises.  Within thirty (30) days after the Effective
Date, Tenant may submit to Landlord a "Punchlist" of incomplete items with
respect to the Tenant Improvements, and Landlord agrees to proceed diligently to
complete such Punchlist items.


          8.  Paragraph 3(a) of the Lease is hereby amended to provide that with
respect to the Additional Premises the Initial Year shall be the calendar year
1995.


                                      -4-
<PAGE>
 
          9. Tenant shall be responsible to pay to Landlord, as Additional Rent,
a monthly charge equivalent to the cost to Landlord of estimated monthly usage
of electrical service within the Additional Premises.  The initial estimated
monthly charge for electrical service to the Additional Premises shall be $847.
Such monthly charge shall be adjusted from time to time by Landlord on a square
foot basis on the basis of the electricity charges paid by Tenant to Landlord
with respect to the original Demised Premises described in the Lease.   Either
party may elect (but not more frequently than once during any calendar year) to
cause a survey of electrical usage of the Additional Premises to be made by a
qualified independent electrical rate consultant, in which event the monthly
charge shall be appropriately adjusted prospectively in accordance with the
results of such survey.  The cost of each such survey shall be paid by the party
requesting it.

            10. The provisions of Paragraph 33 of the Lease shall also apply to
    the portion of the first floor of the Building shown on the floor plan
    annexed hereto as Exhibit B-2 (the "First Floor Offer Space"). The terms of
    Paragraph 33 of the Lease shall apply to the First Floor Offer Space in the
    same manner as they apply to the Third Floor Offer Space.


            11.  Landlord represents that,  as of the date hereof, no mortgage
encumbers the Land.


            12.  Except and as amended hereby, the Lease remains in full force
and effect.


        IN WITNESS WHEREOF, the parties have executed this First Amendment to
Agreement of Lease as to the date first above written.

                      SECOND AMENDMENT TO LEASE AGREEMENT


        THIS SECOND AMENDMENT TO LEASE AGREEMENT is made this 31st day of
January, 1995 between VALLEY NATIONAL BANK, as subtrustee ("Landlord"), having
an office address c/o Gale & Wentworth, 100 Campus Drive, Florham Park, New
Jersey 07932 and SCHEIN PHARMACEUTICAL, INC., a Delaware corporation ("Tenant"),
having an address of 100 Campus Drive, Florham Park, New Jersey 07932.


                                P R E A M B L E
                                - - - - - - - -


        A. By Lease Agreement dated April 16, 1993, amended by First Amendment
to Lease Agreement (the "First Amendment") dated October 26, 1994 (collectively,
the "Lease"), Sammis Morristown Associates, Landlord's predecessor in title,
leased to Tenant and Tenant leased from said party certain premises therein
described on the first and third floors of the office building at 100 Campus
Drive, Florham Park, New Jersey.


        B.  The parties desire to amend the Lease to include the demise of
additional premises on the third floor of the Building.


        C.  All terms not specifically defined herein shall have the meanings
given to them in the Lease.


        NOW, THEREFORE, in consideration of the foregoing, the parties agree
that the Lease is hereby further amended as hereafter provided, effective as of
the later to occur of (i) February 1, 1995, and (ii) the date on which Landlord
delivers possession of the Additional Premises, as defined below, to Tenant free
and clear of all tenancies and occupancies and in "broom clean" condition (such
later date being hereafter referred to as the "Effective Date"):


          1. Upon the occurrence of the Effective Date, the Demised Premises
shall be increased to include the portion of the third floor of the Building
outlined on the floor plan which is annexed hereto as Exhibit A-4 (the
"Additional Premises").  The
<PAGE>
 
gross rentable area of the Additional Premises is 2,242 square feet.


          2. The  Term  with  respect  to  the  Additional Premises shall be
coextensive with the Term with respect to the remainder of the Demised Premises.
The parties confirm and agree that the Expiration Date is August 31, 2005.


          3. The Fixed Rent with respect to the Additional Premises shall  be
$25. per square foot of gross rentable area of office space per annum, i.e.,
$56,050., payable in equal monthly installments of $4,670.83, from the Effective
Date through August 18, 1999 (the sixth (6th) anniversary of the Commencement
Date). Commencing August 19, 1999 and throughout the remainder of the Term, the
Fixed Rent with respect to the Additional Premises shall be $27.75. per square
foot of gross rentable area of office space per annum, i.e., $62,215.50.,
payable in equal monthly installments of $5,184.63.  Therefore, provided that
the First Amendment has become effective, as of the Effective Date the Fixed
Rent for the entire Demised Premises shall be $1,275,165. per annum, payable in
equal monthly installments of $106,263.75, through August 18, 1999. Commencing
August 19, 1999 and for the remainder of the Term, the Fixed Rent for the entire
Demised Premises shall be $1,423,298.75 per annum, payable in equal monthly
installments of $118,608.23.


          4. Tenant's Proportionate Share with respect to the Additional
Premises is 63/100 percent (.63%).  At such time as the First Amendment is
effective, Tenant's Proportionate Share with respect to the entire Demised
Premises shall be fourteen and 87/100 percent (14.87%).


          5. With  respect  to parking,  Tenant  shall  be entitled  to nine
(9)  additional Non-Exclusive Spaces.    Upon addition of the Additional
Premises to the Demised Premises, Tenant would qualify for one additional
Exclusive Space under Paragraph 23 of the Lease, except that no such space is
currently available for Tenant.

                                      -2-
<PAGE>
 
          6. A.  The Additional Premises shall be delivered to Tenant "as is" on
the Effective Date and, except as hereafter provided,  Landlord shall have no
obligation with respect to the fit-up thereof.  Any work performed by Tenant in
the Additional Premises  (the "AP Work")  shall be subject to all applicable
provisions of the Lease, including Paragraph 6 thereof.  Landlord hereby grants
to Tenant an improvement allowance for the AP Work in the amount of $22,420.
(the "Improvement Allowance").   Within thirty (30) days after the presentation
to Landlord of invoices covering AP Work, together with such other documentation
as may be reasonably requested by Landlord, Landlord shall reimburse Tenant for
the  amount  of  such  invoices,  up to  the  amount  of  the Improvement
Allowance. Any unused Tenant Allowance with respect to the premises demised by
the First Amendment may be utilized by Tenant with respect to the AP Work.  No
allowance shall be payable by Landlord, except for work actually performed by or
for Tenant in the Additional Premises or in the premises demised by the First
Amendment within one year after the Effective Date.  Tenant shall be solely
responsible for the cost of all AP Work which exceeds the Improvement Allowance.


          B.   Landlord's contractor, Gale & Wentworth Construction Co.  ("G&W")
shall have the right to bid for the AP Work against contractors selected by
Tenant from a list of approved contractors prepared by Tenant and approved by
Landlord, which approval shall not be unreasonably withheld or delayed.  If the
bid of G&W is equal to, less than or not more than five percent (5%) in excess
of the bid of another contractor which Tenant is willing to accept, Tenant
agrees to accept the bid of G&W to do the AP Work. Furthermore,  if the bid of
G&W exceeds the bid of Tenant's preferred contractor by more than five percent

same basis per square foot as that provided in Paragraph 9 of the First

underlying leases, ground leases or mortgages encumbering the Land or the
Building.

          10.  This Second Amendment to Lease Agreement is contingent upon
Landlord securing, prior to January 23, 1995, a termination of an existing lease
of the Additional Premises from The Arbitration Centre, Inc.  If Landlord is
unable to secure such termination by January 23, 1995, this Second Amendment to

and effect.


        IN WITNESS WHEREOF, the parties have executed this Second Amendment to
Lease Agreement as to the date first above written.

<PAGE>
 
all of the requirements contained herein.

      All insurance policies required of Tenant shall: (a) provide at least
thirty (30) days prior notice to Landlord and Tenant of any change,
modifications or cancellation; and (b) contain a waiver of subrogation of the
rights of the Tenant's insurance carrier to proceed against the Landlord for

policies.

accident or similar occurrence.

alterations, additions, property, appurtenances, or similar items that are not
the property of Landlord in or upon the Premises and agrees that Landlord is not
and shall not be obligated to repair any damage or loss thereto, nor replace
same, nor compensate any person or party for any loss, damage, or destruction
regardless of cause and/or reason.

Premises, no penalty shall accrue for reasonable delay which may arise by reason
of adjustment of insurance on the part of Landlord and/or Tenant, or for delays
on account of labor troubles or other reasons or causes beyond Landlord's
control.

limited to, smoke detectors and heat sensors), or any changes, modifications,
alterations, or the installation of additional sprinkler heads or other
equipment for any existing sprinkler, fire extinguishing system,

any reason, whether or not attributable to Tenant's use of the Premises or
Alterations performed by or on behalf of Tenant; OR

sprinkler heads, or other equipment become necessary to prevent the imposition
of a penalty, an additional charge, or an increase in the fire insurance rate as

company as a result of the use of the Premises whether or not the same is a
permitted use as defined elsewhere herein, then Tenant shall, at Tenant's sole

to which Landlord may be subject or which Landlord may sustain relating to

posted within the road/driveway system of the Cherry Hill Industrial Center; (2)
obey fire regulations and procedures governing the premises; (3) keep access
lids on exterior waste storage containers in a closed position except when waste

      g. Landlord shall have the right to prohibit any advertising by any Tenant
which, in Landlords reasonable judgment, tends to impair the reputation of said
Tenant's Premises or the Cherry Hill Industrial Center, and upon notice from
Landlord, such Tenant shall refrain from or discontinue such advertising.
Landlord shall have the right to enforce this provision by injunction.

      h. Landlord's employees shall not be required to perform, and


                                        9
<PAGE>
 
shall not be required by tenant to perform, any work outside of their regular
duties, unless under specific instructions from the office of Landlord.

      i. Tenant shall immediately notify Landlord of any serious breakage, or
fire or disorder, occurring within the Premises.

      j. Landlord reserves the right to rescind, amend, alter or waive any of
the foregoing Rules and Regulations at any time when, in its judgment, it deems
it necessary, desirable or proper for its best interest and/or for the best
interest of the tenants, and no such recission, amendment, alteration or waiver
of any rule or regulation in favor of one Tenant shall operate as an alteration
or waiver in favor of any other Tenant. Any such rescission, amendment,
alteration, or waiver shall become effective ten (10) days after notice by
Landlord to Tenant.

      k. Nothing contained in this Lease shall be construed to impose upon
Landlord any duty or obligation to impose the rules and regulations against any
other Tenant or any employees or agents of any other Tenant, and Landlord shall
not be responsible or liable to Tenant or others for non-observance or violation
of the rules and regulations by any other Tenant or its employees, agents,
invitees or licensees at any time.

      l. Tenant, its employees, contractors, agents, assignees, sublessees,
invitees, licensees and similar parties shall obey and observe all reasonable
rules and regulations established by Landlord from time to time for the conduct
of Tenant and/or the welfare, care, cleanliness, preservation of good order,
and/or safety of the Cherry Hill Industrial Center. Landlord shall give Tenant
at least (10) days notice of the establishment thereof. Nothing contained in
this Lease shall be construed to impose upon Landlord any duty or obligation to
enforce the rules and regulations against any other Tenant or any employees or
agents of any other Tenant, and Landlord shall not be liable to Tenant or others
for violations of the rules and regulations by any other Tenant or its
employees, contractors, agents, invitees, licensees or similar parties.

21. EMINENT DOMAIN. If the Premises or any portion thereof are taken under the
power of eminent domain, this Lease shall terminate as to the part so taken as
of the date the condemning authority takes title. If more than 10% of the floor
area of the Premises, or more than 25% of the non floor area of the Premises is
taken by condemnation, Tenant may, at Tenant's option, to be exercised by
written notice to the Landlord within 10 days after the Landlord shall have
given Tenant notice of such taking, terminate this Lease as of the date the
condemning authority takes title. If Tenant does not terminate this Lease in
accordance with the foregoing, this Lease shall remain in full force and effect
as to the portion of the Premises remaining, except that the rent shall be
reduced in proportion to the floor area of the Premises taken to the total floor
area of the Premises. Any award for taking of all or any part of the Premises
under the power of eminent domain or any payment made under threat of the
exercise of such power shall be the property of the Landlord, whether such award
shall be made as compensation for diminution in value of the Leasehold or for
the taking of the fee, or as severance damages, or other compensation to which
Landlord may be entitled. Tenant may make a separate application for
compensation relating to its trade fixtures or personal property.


                                       10

22. FORCE MAJEURE. Except as the effect of this paragraph may be expressly
excluded in other provisions hereof, the parties shall be excused for the period
of any delay in the performance of any obligation hereunder when prevented from
so doing by a cause or causes beyond the parties control which shall include,
without limitation, all labor disputes, civil commotion, war, war-like
operations, invasion, rebellion, hostilities, military or usurped power
sabotage, governmental regulations or controls, fire or other casualty, or
through Acts of God.

23. LANDLORDS NON-LIABILITY. Except as is specifically provided for herein:

      Landlord shall not be liable or responsible for any loss or damage to any
property regardless of its nature or ownership at any time on or about the
Premises arising from any cause or reason whatsoever. Nor shall Landlord be
liable or responsible for any harm or injury (including death) to any person at
any time on or about the Premises, arising from any cause or reason whatsoever.
Tenant shall not hold Landlord in any way responsible or liable therefor and
hereby releases and remises Landlord therefrom.

      Without limiting or diminishing Landlord's non-liability as provided for
herein, Landlord shall not be responsible or liable to Tenant, its employees,
invitees, agents, or any other party for any loss or damage to any property or
harm or injury to any persons (including death): (a) which is and/or should have
been covered by an insurance policy required of Tenant or which Tenant failed to
obtain or keep in force and effect; (b) caused by work stoppages, business
interruptions, or similar events; (c) caused by other Tenants, its agents,
invitees, employees, and similar parties; (d) caused by operations in
construction of any private, public or quasi-public works; (e) caused by any
latent or patent defects in the Premises or in any part of the building of which
the Premises may form a part; (f) arising out of the design or construction of
the Premises; (g) caused by snow, wind, rain, leakage, and similar events into
or out of any portion of the Premises; (h) caused by leakage, overflows,
obstructions, blockages, explosions, collapse, bursts, surges, and similar
events of any mechanical, structural, or other component and/or part thereof;
(i) arising from or caused by Tenant's business operation, occupancy and/or use
of the Premises and/or the streets, rights of way, and walkways adjacent
thereto, or any other similar reason.

      All non-liability, waivers of liability, and save and hold harmless
references in this Lease given Cherry Hill Industrial Sites, Inc., as Landlord,
shall apply to (a) Cherry Hill Industrial Sites, Inc., as General Contractor,
Designer, Contractor, or Subcontractor; and (b) any partner, joint venturer,
director, officer, agent, stockholder, and employee of Cherry Hill Industrial
Sites, Inc.

24. INDEMNIFICATION. Tenant shall not do, nor permit to be done, any act or
thing in or upon the Premises, which may, will, or does subject Landlord to any
claims, penalties, expenses, judgments, responsibility, liability, damages or
similar occurrence by reason of damage or loss to any property or harm and/or
injury (including death) to any persons at any time.

      Tenant agrees to and shall hold and save harmless and indemnify the
Landlord from and for any and all payments, expenses, costs, attorney fees,
claims and liability for losses or damage to property


                                       11
<PAGE>
 
and/or injury to any person (including death) resulting from any acts or
omissions by the Tenant, or its agents, employees, guests, licensees, invitees,
sub-tenants, contractors and similar parties, or for any cause or reason arising
out of or by reason of Tenant's use and/or occupancy of the Premises and/or the
conduct of Tenant's business and/or the breach by Tenant of any of the terms and
conditions of this Lease and/or similar reason.

25. FAILURE TO GIVE POSSESSION. If Landlord, for any reason, shall be unable to
give possession of the Premises on the date set for the commencement of the
Term, Landlord shall not be subject to any liability for such failure. Under
such circumstances, provided the delay is not caused or contributed to by
Tenant, the rent payments shall not commence until possession of the Premises is
given or the Premises are available for occupancy by Tenant, whichever occurs
first. Failure to give possession on the date of commencement of the term shall
in no way affect the validity of this Lease or the obligations of Tenant
hereunder nor shall it be construed in any way as an extension to the Term or
expiration date of this Lease.

      If Landlord, at its option, grants Tenant permission to enter into the
possession of the Premises prior to the date specified as the commencement of
the Term, Tenant agrees that such occupancy shall be pursuant to the terms and
conditions of this Lease.

26. LIENS. Tenant shall not do anything which shall interfere with Landlord's
rights of ownership in the Premises. Tenant shall not permit nor allow any
notice of intention to file any type of lien (including, but not limited to,
mechanics liens) to be filed against the Premises. However, in the event any
notice of intention to file a lien is filed for work to be performed, material
to be furnished, or a lien is filed for work claimed to have been done or for
materials claimed to have been furnished to Tenant, same shall be discharged of
record and satisfied by Tenant within five (5) days thereafter at Tenant's own
cost and expense, or Tenant shall file a bond pursuant to statute releasing such
liens. Failure to do so shall entitle Landlord to resort to such remedies as are
provided herein in case of any default of this Lease, in addition to such as are
permitted by law.

27. ACCESS TO PREMISES. Landlord, its employees and agents shall have the right
to enter the Premises at all reasonable times for the purpose of: (a) examining
or inspecting the same; (b) showing the same to prospective purchasers,
mortgagees or Tenants; (c) making such alterations, repairs, improvements or
additions to the Premises or to the Building as may be necessary; (d) any other
similar or reasonable purpose.

      If representatives of Tenant shall not be present to open and permit entry
into the Premises at an time when such entry by Landlord is necessary or
permitted hereunder, Landlord may enter by means of a master key (or forcibly in
the event of an emergency) without: (a) liability to Landlord, its employees,
agents, invitees and similar parties; (b) hindrance or molestation from Tenant,
its employees, and agents; and (c) such entry constituting an eviction of Tenant
or termination of this Lease.

28. ASSIGNMENT.

      a. Tenant shall not assign, mortgage, pledge, encumber or in any manner
transfer this Lease or any portion thereof, or any interest


                                       12
<PAGE>
 
herein, or sublet the whole or any part of the Premises, without obtaining the
approval of Landlord. In the event of any such occurrence, with or without
Landlord's approval, Tenant shall, nevertheless, remain liable for the
performance of all the terms and conditions of this Lease and will require any
assignee/sublessee to execute and deliver to Landlord an assumption of all of
the terms and conditions of this Lease in form satisfactory to Landlord.
Landlord shall be entitled to, and Tenant shall promptly remit to Landlord, any
profit which may inure to the benefit of Tenant as a result of any partial or
entire subletting of the Premises or assignment of this Lease, whether or not
approved by Landlord.

      b. For the purposes of this paragraph, Tenant understands that the
transfer of a majority of Tenant's stock is tantamount to an assignment.

      c. As a condition precedent to Tenant's right to sublease the Premises or
to assign this Lease, Tenant shall, at Tenant's own expense, first comply with
ECRA and fulfill all of Tenant's environmental obligations under this Lease
pursuant to paragraph 51 which also arise upon termination of Tenant's lease
term. If this condition is not satisfied, then Landlord shall have the right to
withhold consent to sublease or assignment.

      Tenant shall promptly furnish to Landlord true and complete copies of all
documents, submissions and correspondence provided by Tenant to the NJDEP and
all documents, reports, directives and correspondence provided by the NJDEP to
Tenant. Tenant shall also promptly furnish to Landlord true and complete copies
of all sampling and test results obtained from samples and tests taken at and
around the Premises. Tenant shall notify Landlord in advance of all meetings
scheduled between Tenant and NJDEP, and Landlord may attend all such meetings.

      d. Should Tenant make an assignment or sublet the Premises or any portion
thereof without the approval of Landlord, then Landlord may, at its option,
terminate this Lease by giving Tenant five (5) days notice of Landlord's
intention to do so and, upon the expiration of five (5) days, this Lease shall
terminate and Tenant shall peaceably quit and surrender the Premises to
Landlord; nevertheless Tenant shall remain liable as provided elsewhere in this
Lease. This Lease shall not, nor shall any interest therein, be assignable as to
the interest of Tenant by operation of law, without the approval of Landlord.

      e. Subletting or assigning this Lease to anyone other than an actual user
of the Premises is positively prohibited.

      f. Tenant may assign this Lease or sublet the Premises or any part thereof
to a subsidiary or controlled or affiliated concern of Tenant and of its parent,
or a surviving company of a merger or consolidation of any of the foregoing
without the Landlord's consent. Tenant is expressly granted consent to assign or
sublet the Premises, or any portion thereof, to a wholly owned subsidiary.

29. SUBORDINATION. This Lease shall be subject and subordinate at all times to
the lien of any mortgages and/or other encumbrances, common right-of-way's,
easements and similar items existing or hereafter placed upon the Premises by
Landlord, or with the permission of Landlord, without the necessity of any
further instrument or act on the part of Tenant to effectuate such
subordination. Tenant agrees, however, at the election of a mortgagee, to attorn
to any holder of any mortgage to which this Lease is subordinate. Tenant agrees
to


                                       13
<PAGE>
 
execute and deliver promptly upon demand, and without charge, such further
instrument or instruments evidencing such subordination of this Lease to the
lien of any mortgage and/or other encumbrance. Tenant hereby irrevocably
appoints Landlord as Tenant's attorney in fact to execute and deliver such
instrument or instruments for and in the name of the Tenant provided same have
not been executed by Tenant within ten (10) days after Landlord's notice to
Tenant.

      Landlord agrees that the subordination of the Lease to any future mortgage
relating to the Premises shall be conditional and contingent upon any such
mortgagee's agreeing that, so long as Tenant is not in default under the terms
and conditions of the Lease, such mortgages shall not disturb Tenant's use,
possession and occupancy of the Premises.

30. CERTIFICATIONS. Tenant agrees, within ten (10) days after Landlord's notice,
to execute, acknowledge and deliver to Landlord a written instrument in
recordable form certifying: (1) that this Lease is unmodified and in full force
and effect (or if there have been modifications, that the same are in full force
and effect as modified and stating the modifications); (2) that the Tenant has
accepted possession of the Premises and the date on which the term of the Lease
commenced; (3) the dates to which rent and additional rent have been paid in
advance, if any; (4) whether or not to the best knowledge of the signer of such
certificate, Landlord is in default in the performance of any covenant of this
Lease, and, if so, specifying each such default of which the signers may have
knowledge; (5) any other reasonable stipulation as may be required and/or
requested by Landlord. It is understood that such instrument may be relied upon
by a prospective purchaser of the fee or any mortgagee of the Premises.

      Tenant shall provide to Landlord, if requested, its latest audited
financial statement, accurately reflecting its financial condition for the
latest fiscal year of Tenant. It is understood that such statement may by relied
upon by a prospective purchaser of the fee or any mortgagee of the Premises.

31. DEFAULT AND REMEDIES.

      a. Default. The occurrence of any of the following shall constitute a
material default and breach of this Lease by Tenant:

            (1) Failure of Tenant to accept possession of the Premises within
thirty (30) days after the effective date of the Lease;

            (2) The vacating or abandonment of the Premises by Tenant;

            (3) The failure by Tenant to pay, when due, any installment of rent
hereunder or any additional rent or any such other sum herein required to be
paid by Tenant;

            (4) A failure by Tenant to observe and perform any other provision
or terms and conditions of this lease to be observed or performed by Tenant,
where such failure continues for fifteen (15) days (or a lesser time period when
an emergency or law requires or makes such a reduction for abatement and/or
correction prudent; or when a lessor of non notice provision is specifically
provided for in any covenant of this Lease) after written notice thereof from
Landlord to Tenant provided, however, that if the nature of the default is such
that the same cannot reasonably be cured within such fifteen (15) day period,
Tenant shall not be deemed to be in default if Tenant shall within such period
commence such cure and thereafter diligently prosecute the same to completion;


                                       14
<PAGE>
 
      b. Remedies. Upon the occurrence of any such event of default set forth
above;

            (1) Landlord may (but shall not be required to) perform for the
account of Tenant the curing of any default of Tenant and immediately recover as
additional rent any expenditure made and the amount of any obligations incurred
in connection therewith, plus interest at the rate of four percent (4%) per
annum over the Midlantic National Bank/South prime rate from the date of such
expenditure;

            (2) Tenant may cure any monetary default by making payment of the
monies due, together with a late charge of 5% of the amount due not later than
ten (10) calendar days after notice of the default has been given to Tenant. If
said default should continue for a longer period, Landlord may accelerate all
rent and additional rent due for the succeeding nine (9) months of the term of
this Lease and declare the same to be immediately due and payable.

            (3) Tenant may cure any non-monetary default by correcting the
default condition described in Landlord's notice to Tenant if said corrections
are completed within twenty (20) calendar days after notice of the default has
been given to Tenant. If said default should continue for a longer period,
Landlord may accelerate all rent and additional rent due for the succeeding nine
(9) months of the term of this Lease and declare the same to be immediately due
and payable.

            (4) In the event of default, and the failure of Tenant to cure same
within the designated time period, Landlord, at its option, may serve notice
upon Tenant that this Lease and the then unexpired term hereof and all renewal
options shall cease and expire and become absolutely void on the date specified
in such notice, to be not less than five (5) days after the date of such notice
without any right on the part of the Tenant to save the forfeiture by payment of
any sum due or by the performance of any terms, provision, covenant, agreement
or condition broken; and, thereupon and at the expiration of the time limit in
such notice, this Lease and the term hereof granted, as well as the right, title
and interest of the Tenant hereunder, shall wholly cease and expire and become
void in the same manner and with the same force and effect (except as to
Tenant's liability) as if the date fixed in such notice were the date herein
granted for expiration of the term of this Lease. Thereupon, Tenant shall
immediately quit and surrender to Landlord the Premises, and Landlord may enter
into and repossess the Premises by summary proceedings, detainer, ejectment or
otherwise and remove all occupants thereof and, at Landlord's option, any
property thereon without being liable to indictment, prosecution or damages
therefor. No such expiration or termination of this Lease shall relieve Tenant
of its liability and obligations under this Lease, whether or not the Premises
shall be relet;

            (5) Landlord may, at any time after the occurrence of any event of
default, re-enter and repossess the Premises and any part thereof and attempt in
its own name, as agent for Tenant if this Lease not be terminated or in its own
behalf if this Lease be terminated, to relet all or any part of such Premises
for and upon such terms and to such persons, firms or corporations and for such
period or periods as Landlord, in its sole discretion, shall determine,
including the term beyond the termination of this Lease; and Landlord shall not
be required to accept any tenant offered by Tenant or observe any instruction
given by Tenant about such reletting or do any act or exercise any care or
diligence with respect to such reletting or to the mitigation of damages. For
the purpose of such reletting, Landlord may decorate or make repairs, changes,
alterations


                                       15
<PAGE>
 
or additions in or to the Premises to the extent deemed by Landlord desirable or
convenient; and the cost of such decoration, repairs, changes, alterations or
additions shall be charged to and be payable by Tenant as additional rent
hereunder, as well as any reasonable brokerage and legal fees expended by
Landlord; and any sums collected by landlord from any new tenant obtained on
account of the Tenant shall be credited against the balance of the rent due
hereunder as aforesaid. Tenant shall pay to Landlord monthly, on the days when
the rent would have been payable under this Lease, the amount due hereunder less
the amount obtained by Landlord from such new Tenant;

            (6) The parties recognize and agree that the damage to Landlord
resulting from any failure by Tenant to timely surrender possession of the
Premises will be substantial, will exceed the amount of the monthly installments
of the Rent payable hereunder, and will be impossible to measure accurately.
Tenant therefore agrees that if possession of the Premises is not surrendered to
Landlord upon the expiration date or sooner termination of the Lease, in
addition to any other rights or remedies Landlord may have hereunder or at law,
Tenant shall pay to Landlord, as liquidated damages, for each month and for each
portion of any month during which Tenant holds over in the Premises after the
expiration date or sooner termination of this Lease, a sum equal to two times
the aggregate of that portion of Base Annual Rent and Additional Rent that was
payable under this Lease during the last month of the Term.

            (7) Nothing herein contained shall be deemed to permit Tenant to
retain possession of the Premises after the expiration date or sooner
termination of the Lease.

            (8) In addition to all remedies provided herein or by law, Tenant
shall pay to Landlord reasonable attorneys fees and court costs and any other
expenses incurred as a result of such breach or default.

32. BANKRUPTCY.

      a. Anything elsewhere in this lease to the contrary notwithstanding, this
Lease may be cancelled by Landlord by the sending of a written notice to Tenant
within a reasonable time after the happening of any one or more of the following
events: (1) the commencement of a case in bankruptcy or under the laws of any
state naming Tenant as the debtor; or (2) the making by Tenant of an assignment
or any other arrangement for the benefit of creditors under any state statute.
Neither Tenant nor any person claiming through or under Tenant, or by reason of
any statute or order of court, shall thereafter be entitled to possession of the
premises demised but shall forthwith quit and surrender the premises. If this
Lease shall be assigned in accordance with its terms, the provisions of this
Article 31 shall be applicable only to the party then owning Tenant's interest
in this Lease.

      b. It is stipulated and agreed that in the event of the termination of
this Lease pursuant to (a) hereof, Landlord shall forthwith, notwithstanding any
other provisions of this Lease to the contrary, be entitled to recover from
Tenant as and for liquidated damages an amount equal to the difference between
the rent reserved hereunder for the unexpired portion of the term demised and
the fair and reasonable rental value of the demised premises for the period for
which such installment was payable shall be discounted to the date of
termination at the rate of four percent (4%) per annum. If such


                                       16
<PAGE>
 
premises or any part thereof be re-let by the Landlord for the unexpired term of
said Lease, or any part thereof, before presentation of proof of such liquidated
damages to any court, commission or tribunal, the amount of rent reserved upon
such reletting shall be deemed to be the fair and reasonable rental value for
the part or the whole of the premises so re-let during the term of the
re-letting. Nothing herein contained shall limit or prejudice the right of the
Landlord to prove for and obtain as liquidated damages by reason of such
termination, an amount equal to the maximum allowed by any statute or rule of
law in effect at the time when, and governing the proceedings in which, such
damages are to be proved, whether or not such amount be greater, equal to, or
less than the amount of the difference referred to above.

33. EXPIRATION. Upon the expiration date of this Lease or prior termination
specified by Landlord pursuant to notice as provided for elsewhere in this
Lease: (a) Tenant shall remove all of its personal property from the Premises;
(b) Tenant shall peacefully quit and surrender to Landlord the Premises, broom
clean and in the same condition in which Tenant has agreed to keep it during the
Term. Tenant's obligation to observe or perform this covenant shall survive the
expiration or prior termination date of this Lease; (c) Tenant, for itself and
on behalf of any and all persons claiming through or under it, including, but
not limited to, creditors of every kind, shall and does hereby waive and
surrender all rights and privileges which it may have under or by reason of any
present or future law, to redeem the Premises or to have a continuance of this
Lease; (d) Landlord may enter and repossess the Premises as of Landlord's former
estate and expel Tenant, and those claiming through or under Tenant from the
Premises; (e) Landlord may remove from the Premises any property of Tenant
and/or the property of those cliaming through or under Tenant and, without
notice to Tenant or others, sell such property or any part thereof at public or
private sale or Landlord may treat such property or any part thereof as
abandoned and dispose of same in any manner as Landlord, at its option, elects,
all at the risk and cost of Tenant and without any liability to Landlord
whatsoever.

      If during the last month of the term or prior termination, Tenant has
removed all or substantially all of the Tenant's property from the Premises,
Landlord may, without notice to Tenant, immediately enter the Premises to
renovate and decorate the Premises, without liability to Tenant and without
reducing or otherwise affecting Tenant's obligations hereunder.

34. USE AND OCCUPANCY ON HOLDOVER. Tenant agrees that if possession of the
Premises is not surrendered to Landlord upon the expiration date or sooner
termination of the Lease, in addition to any other rights or remedies Landlord
may have hereunder or at law, Tenant shall pay to Landlord, as use and
occupancy, for each month and for each portion of any month during which Tenant
holds over in the Premises after the expiration date or sooner termination of
this Lease, a sum equal to two times the aggregate of that portion of Base
Annual Rent and Additional Rent that was payable under this Lease during the
last month of the Term.

      Nothing herein contained shall be deemed to permit Tenant to retain
possession of the Premises after the expiration date or sooner termination of
the Lease.


                                       17
<PAGE>
 
35. NON-WAIVER BY LANDLORD. Landlord may restrain any breach or threatened
breach of any covenant of this Lease by Tenant. However, the recitation herein
of any particular remedy shall not preclude the Landlord from any other remedy
it may have, either at law or in equity. Landlord, at its option, may pursue
more than one remedy available either concurrently or separately. The failure of
Landlord to insist upon the strict performance of any one of the terms and
conditions of this Lease or to exercise any right, remedy or election provided
for in this Lease, or permitted by law, shall not constitute or be construed as
a waiver or relinquishment of such right, remedy or election. Landlord may, at
its option, mitigate any damages caused or arising out of Tenant's breach of any
of the terms and conditions of this Lease, but shall not be under any obligation
or duty to do so. Any rights and remedies of Landlord, whether created by the
terms of this Lease or existing at law, in equity, or otherwise, shall be
distinct, separate and cumulative and no one of them, whether exercised by
Landlord or not, shall be deemed to be in exclusion of any other.

      No covenant of this Lease shall be deemed to have been waived by Landlord
unless such waiver is in writing, signed by Landlord.

36. QUIET ENJOYMENT. Landlord covenants that upon Tenant observing and
performing all the terms and conditions of this Lease, Tenant shall and may
peaceably and quietly have, hold and enjoy the Premises for the term
aforementioned.

37. BILLS/NOTICES. Except as otherwise provided in this Lease, any bill,
statement, or notice shall be deemed sufficient if written and delivered to
Tenant personally or sent by certified mail, return receipt requested, to Tenant
at the Premises. The time of mailing of such bill or statement and of the giving
of such notice or communication shall be deemed to be the time when same is
mailed to Tenant as herein provided. Any notice by Tenant to Landlord must be
served by certified mail, return receipt requested, to Landlord at the address
herein given or at such other address as Landlord shall designate.

such locations as shall be first approved by the Landlord and then the

or condition of this Lease, such approval shall be in writing and in advance for
each occurrence. Landlord is under no duty or obligation to grant approvals.

      Whenever this Lease provides for a Landlord's option, it is agreed such

      Whenever this Lease provides for Landlord's approval which shall not be

without any claim on the part of Tenant, or those claiming under Tenant, for
diminution, setoff, deduction, or abatement except as is specifically provided
for herein.

      Tenant's obligation to pay rent and additional rent hereunder, and to

47. COMPLIANCE WITH THE NJ ENVIRONMENTAL CLEANUP RESPONSIBILITY ACT.

      a. Tenant shall, at Tenant's own expense, comply with the Environmental
Cleanup Responsibility Act, N.J.S.A. 13:1K-6 et seq., the regulations
promulgated thereunder and any successor legislation and regulations, and any
amendments or additions thereto, (hereinafter referred to as "ECRA"). Tenant
shall, at Tenant's own expense, make all submissions to, provide all information
to, and comply with all requirements of, the Industrial Site Evaluation or its
successor ("Element") of the New Jersey Department of Environmental Protection
("NJDEP").

      b. Tenant's obligations under this paragraph shall arise if there is any
closing, termination or transferring of operations of an industrial
establishment at the premises pursuant to ECRA, whether triggered by Landlord or
Tenant.

      c. Provided this Lease is not previously cancelled or terminated by either
party or by operation of law, Tenant shall commence its submission to the
Element in anticipation of the end of the lease term no later than one (1) year
prior to the expiration of the lease term. Tenant shall promptly furnish to
Landlord true and complete copies of communications provided by Tenant to the
Element, and all documents, reports, directives, correspondence and oral or
written communications by the Element to Tenant. Tenant shall also promptly
furnish to Landlord true and complete copies of all sampling and tests taken at
and around the Premises. Tenant shall notify Landlord in advance of all meetings
scheduled between Tenant and NJDEP, and Landlord may attend all such meetings.

      d. Should the Element or any other division of NJDEP determine that a
cleanup plan be prepared and that a cleanup be undertaken because of a spill or
discharge of a hazardous substance or waste at the Premises which occurred
during the term of the Lease, Tenant shall, at Tenant's own expense, promptly
prepare and submit the required plan and financial assurances and shall promptly
carry out the approved plans.

      e. At no expense to Landlord, Tenant shall promptly provide all


                                       20
<PAGE>
 
information requested by Landlord or NJDEP for preparation of a
non-applicability affidavit, de minimus quantity exemption application, negative
declaration application, limited conveyance application or other submission and
shall promptly sign such affidavits and submissions when requested by Landlord
or NJDEP.

      f. Should Tenant's operations at the Premises be outside of those
industrial operations covered by ECRA, Tenant shall, at Tenant's own expense,
obtain a letter of non-applicability or de minimus quantity exemption from the
Element prior to termination of the Lease term and shall promptly provide
Tenant's submission and the Element's exemption letter to Landlord. Should
Tenant obtain a letter of non-applicability or de minimus quantity exemption
from the Element, then Tenant shall, at Landlord's option, hire a consultant
satisfactory to Landlord to undertake sampling at the Premises sufficient to
determine whether or not Tenant's operations have resulted in a spill or
discharge of a hazardous substance or waste at or around the Premises. Should
the sampling reveal any spill or discharge of a hazardous substance or waste,
the Tenant shall, at Tenant's expense, promptly clean up the Premises to the
satisfaction of Landlord and NJDEP.

      g. If Tenant fails to obtain either: (i) a non-applicability letter; (ii)
a de minimus exemption; (iii) a negative declaration; or (iv) final approval of
cleanup; (collectively referred to as "ECRA clearance") from the Element; or
fails to clean up the Premises pursuant to subparagraph (f) above, prior to the
expiration or earlier termination of the lease term, then upon the expiration or
earlier termination of the lease term Landlord shall have the option either to
consider the Lease as having ended or to treat Tenant as a holdover tenant in
possession of the Premises. If Landlord considers the lease as having ended,
then Tenant shall nevertheless be obligated to promptly obtain ECRA clearance
and to fulfill the obligations set forth in subparagraph (f) above. If Landlord
treats Tenant as a holdover tenant in possession of the Premises, then Tenant
shall monthly pay to Landlord double the regular and additional monthly rent
which Tenant would otherwise have paid, until such time as Tenant obtains ECRA
clearance and fulfills its obligations under subparagraph (f) above, and during
the holdover period all of the terms of this Lease shall remain in full force
and effect.

      h. Tenant represents and warrants to Landlord that Tenant intends to use
the Premises for activities relating to the warehousing and distribution of
pharmaceutical products. Tenant's use of the Premises shall be restricted to the
classifications set forth above unless Tenant obtains Landlord's written prior
written consent to any change in use of the Premises. Prior to the commencement
date of Tenant's lease term, Tenant shall supply to Landlord an affidavit of an
officer of Tenant ("Officer's Affidavit") setting forth Tenant's SIC numbers and
a detailed description of the operations and processes Tenant will undertake at
the Premises, organized in the form of a narrative report including a
description and quantification of hazardous substances and wastes to be
generated, manufactured, refined, transported, treated, stored, handled or
disposed of at the Premises. Following commencement of the lease term, Tenant
shall notify Landlord by way of a supplemental Officer's Affidavit, as to any
changes in Tenant's operation, SIC number or use or generation of hazardous
substances and wastes. Tenant shall also supplement and update Officer's
Affidavit upon each anniversary of the commencement of the lease term. Tenant
shall not commence or alter any operations


                                       21
<PAGE>
 
at the Premises prior to (i) obtaining all required operating and discharge
permits or approvals, including, but not limited to, air pollution control
permits and pollution discharge elimination system permits from NJDEP, all
governmental or public authorities having jurisdiction over Tenant's operations
or the Premises, and (ii) providing copies of permits and approvals to Landlord.

      i. Tenant shall permit Landlord and Landlord's agents, servants and
employees, including but not limited to, legal counsel and environmental
consultants and engineers, access to the Premises for the purposes of
environmental inspections and sampling during regular business hours, or during
other hours either by agreement of the parties or in the event of any
environmental emergency. Tenant shall not restrict access to any part of the
Premises, and Tenant shall not impose any conditions to access. In the event
that Landlord's environmental inspection shall include sampling and testing of
the Premises, Landlord shall use its best efforts to avoid interfering with
Tenant's use of the Premises, and upon completion of sampling and testing shall
repair and restore the affected areas of the Premises from any damage caused by
the sampling and testing.

      j. Tenant's indemnification of Landlord as set forth elsewhere within this
Lease shall extend to any and all claims, liabilities, losses, damages, and
costs, foreseen or unforeseen, including without limitation counsel, engineering
and other professional or expert fees, which Landlord may incur by reason of
Tenant's action or non-action with regard to Tenant's obligations under this
paragraph.

      k. This paragraph shall survive the expiration or earlier termination of
this Lease. Tenant's failure to abide by the terms of this paragraph shall be
restrainable by injunction without limiting Landlord's right to remedy as
provided for elsewhere in this Lease.

Landlord deems necessary or appropriate to determine the applicability of the
Laws to the Premises and Tenant's use thereof, and for compliance therewith, and
Tenant shall execute all documents promptly upon Landlord's request. No such
action by Landlord and no attempt made by Landlord to mitigate damages under any
Law shall constitute a waiver of any of Tenant's obligations under this
sub-paragraph c.

      d. Tenant's Indemnity.

            Tenant shall indemnify, defend and hold harmless Cherry Hill
Industrial Sites, Inc. as Landlord, Landlord and Contractor, and its officers,

Hazardous Substances that occurs during the term of this Lease, at or from the
Premises, or which arises at any time from Tenant's use or occupancy of the
Premises, or from Tenant's failure to provide all information, make all
submissions, and take all steps required by all Authorities under the Laws and

survive the natural expiration or sooner termination of this Lease.

            Buyer shall make a payment of FIVE MILLION AND THREE HUNDRED

may designate.

      The following adjustments and payments shall be made at Closing:

      a. Real property taxes for the then current year relating to the Premises

<PAGE>
 
3. TITLE TO PREMISES. At Closing, Seller shall convey to Buyer, by special
warranty deed, good and marketable title of record in fee simple to the
Premises. All costs related to closing shall be paid by Buyer. Such costs shall
be deemed to include real property taxes, real estate transfer taxes, sewer
charges and other municipal and local taxes, assessments and levies upon the
property which are required by the title company or Buyer's lender to be paid.

      The Buyer shall be required to accept at closing those restrictions of
record that may appear on the title report to be issued by Continental Title
Insurance Company, 8000 Sagemore Drive, Suite 8202, Marlton, NJ 08053 (Required
Encumbrances). Buyer further agrees that it will execute the easements, attached
hereto as Exhibits B and C, relating to the private road system in the
industrial center in which building #31 and this premises are situated. Buyer
acknowledges that the documents will be recorded along with the deed.

      The Seller represents and warrants to the Buyer that it presently has
marketable title in fee simple to the premises subject only to those exceptions
listed in the title report, to be provided. The Seller further warrants that it
will not cause or permit any adverse changes in its title to the premises at any
time prior to the Closing of Title. If the title report requires actions or
payments by the Seller in order to preserve Seller's title, the Seller will
promptly make all of said payments and will promptly perform all of said acts
without permitting any default.

      If at the Closing Date there may be any mortgages, liens or encumbrances
which Seller is obligated to pay and discharge, Seller may use all or any
portion of the Purchase Price payable at the Closing to satisfy the same,
provided (i) Seller shall simultaneously deliver instruments in recordable form
and sufficient to satisfy such mortgages, liens and encumbrances of record
together with the cost of recording or filing said instruments which the title
company employed by Buyer shall approve in order to omit such mortgages, liens
and encumbrances from Buyer's title insurance commitment; or (ii) Seller shall
have made arrangements with the title company employed by Buyer in advance of
Closing, which are acceptable to and required by it, to insure the obtaining and
recording of such satisfactions and the issuance of title insurance to Buyer
free of any such liens and encumbrances.

4. COMPLIANCE WITH ECRA. Buyer shall have the obligation of affirmatively
complying with all of the requirements of the New Jersey Environmental Cleanup
Responsibility Act, N.J.S.A. 13:1K-6 et seq ("ECRA"), or, in the alternative, to
obtain a letter of non-applicability stating that the transaction contained in
the agreement of sale is not a transaction which triggers the application of
ECRA.

      In the event that the sale of the property requires that the property be
reviewed pursuant to ECRA, then Buyer shall notify the New Jersey Department of
Environmental Protection ("NJDEP") and submit all necessary forms and fees in a
timely manner so that closing is not delayed beyond the time designated in the
agreement.

      Buyer shall indemnify, defend and hold Seller harmless from
<PAGE>
 
and against all claims, liabilities, losses, damages and costs, foreseen and
unforeseen, including, without limitation, counsel, engineering and other
professional expert fees, which Seller may incur by reason of Buyer's action or
non-action with regard to Buyer's obligation under this paragraph. This
paragraph shall survive closing of title.

5. BUYER'S REPRESENTATIONS. Buyer represents and warrants to Seller that:

      a. Buyer has the legal right, power and authority to enter into this
Agreement and to consummate the transactions contemplated hereby, and the
execution, delivery and performance of this Agreement have been duly authorized

Premises nor does any person or entity other than Buyer have any right or option
to acquire the Premises.

      c. Seller has not received written notice, and Seller is not aware, of
pending or contemplated condemnation proceedings affecting the Premises or any
part thereof as of the date of this Agreement, and, if Seller receives any such
written notice or such information prior to Closing, Seller agrees to provide
Buyer with such information, including a copy of any written notice.

      d. Seller has not received written notice, and Seller is not aware, of any
default or breach under any covenant, condition, restriction, right-of-way or
easement affecting the Premises, or any portion thereof as of the date of this

including a copy of any written notice.

      e. Seller is a corporation of the State of New Jersey in good standing.

      f. Seller has not received any written notice, and Seller is not aware, of

date of this Agreement, and, if Seller receives any such written notice or such
information prior to Closing, Seller agrees to provide Buyer with such
information, including a copy of any written notice.

      g. Seller has not received any written notice from the holder(s) of any
mortgages upon the Premises, any insurance company which has issued a policy
with respect to the Premises,
<PAGE>
 
or any board of fire underwriters (or other body of similar functions) claiming
any default in Seller's performance under said documents and, if Seller receives
any such written notice prior to Closing, Seller agrees to provide Buyer with a
copy thereof.

      h. Seller has received no written notice, and Seller is not aware, of any
litigation or administrative or governmental proceeding pending or threatened
against or relating to the title to the Premises or which would materially
adversely affect Buyer's purchase, ownership, operation of, construction and
development of the Premises as of the date of this Agreement, and, Seller shall
give to Buyer prompt notice of the institution of any such litigation or
proceeding prior to the Closing of which Seller receives written notice or of
which Seller becomes aware, and Seller agrees to provide Buyer with such
information including a copy of any written notice.

7. CONDITION OF THE PREMISES. Buyer acknowledges and agrees that, other than is
expressly set forth elsewhere in this Agreement, Seller has made no
representations or warranties regarding the Premises, including, without
limitation, its condition, its past use, or its suitability for Buyer's intended
use thereof, and that Buyer is acquiring the Premises on an "AS IS" basis.

8. ASSIGNABILITY. The Buyer may not assign its rights and duties under this
Contract.

9. NOTICE. All notices, requests, consents, approvals or other communications
under this Agreement shall be in writing and mailed by U.S. Registered or

10. ENTIRE AGREEMENT. This Agreement contains the entire agreement between the
parties. This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective heirs, legal representatives, successors
and/or assigns.

11. AMENDMENT AND WAIVER. Any provisions of this Agreement may be amended or
waived, but only if such amendment or waiver is in writing and is signed by all
parties to this Agreement.

12. APPLICABLE LAW. This Agreement and the rights of the parties hereunder shall
be construed in accordance with and governed by the laws of the State of New
Jersey.

13. SEVERABILITY. In the event any one or more provisions of this Agreement
shall be determined to be void or unenforceable by a court of competent
jurisdiction or by law, such determination will not render this Agreement
invalid or unenforceable and the remaining provisions hereof shall remain in
full force and effect.

14. Said premises are sold and conveyed subject to the following:

      (a) any state of facts an accurate survey or physical inspection may show
      provided same does not render title
<PAGE>
 
      unmarketable; (b) covenants, restrictions, easements, reservations,
      consents and agreements of record, if any, provided same are not violated
      by the existing structure and present use thereof and/or render title
      unmarketable; (c) rights, if any, acquired by the utility company to
      maintain and operate lines, wires, cables, poles, etc., in, over, and upon
      said premises; (d) street widenings, existing or proposed, if any,
      provided same do not encroach on existing buildings or violate their
      present use; (e) the violations of any covenant or restriction shall not
      be deemed an objection to title provided the title company insuring title
      shall agree to insure that such improvements may remain in their present
      location as long as same shall stand.

15.   Seller and Buyer each warrants and represents to the other that it has
      dealt with no broker which would result in a commission or other
      compensation being due with respect to the sale of the premises and Seller
      and Buyer each agree to indemnify and hold the other harmless with respect
      to any judgment, damages, legal fees, court costs and any liabilities of
      any nature whatsoever arising from breach of its representation.

16.   All prior understandings and agreements between Seller and Buyer are
      merged into this agreement. It completely expresses their full agreement.
      It has been entered into after full investigation, neither party relying
      upon any statements made by anyone else that are not set forth in this
      agreement.

17.   If Seller is unable to transfer title to Buyer in accordance with this
      agreement, Seller's sole liability shall be to refund all money paid on
      account of this agreement, plus all charges made for (i) examining the
      title; (ii) any appropriate additional searches made in accordance with
      this agreement, and (iii) survey and survey inspection charges. Upon such
      refund and payment this agreement shall be considered concelled, and
      neither Seller nor Buyer shall have any further rights against the other.

18.   The parties agree, subject to those contingencies and conditions to
      closing contained herein, that in the event Buyer fails to comply with any
      of the terms of this Agreement and closing does not take place on the
      Closing date as set forth in this Agreement, then the damage which Seller
      will sustain as a result thereof will be substantial but will be
      difficult, if not impossible, to ascertain.

            The parties therefore agree that in such event Seller's sole and
      exclusive remedy shall be to terminate this Agreement, in which event all
      obligations hereunder shall be deemed null and void, and to retain the
      Deposit as liquidated damages, to recompense Seller for time spent, labor
      and services performed, and loss of the benefit of its bargain.

19.   Except as is otherwise specifically provided, no
<PAGE>
 
      representations or warranties by Seller shall survive the passage of the
      deed.

20.   Closing proceeds will be paid by certified or bank check or draft. Third
      party endorsed checks, whether certified or bank checks, and uncertified
      funding company, mortgage broker, attorney or private mortgage company
      checks or drafts shall not be deemed to be acceptable funds hereunder.

21.   In any construction of the terms of this agreement, none of its terms
      shall be construed against the Sellers or their attorney by reason of the
      fact that the Sellers or their attorney drew the agreement since the final
      terms of this agreement are the result of negotiations by parties having
      equal bargaining power, with each of the parties having full access to
      legal representation.

22.   Buyers, at least ten (10) days before the date scheduled for closing,
      shall furnish Seller's attorney with any objections to title which may
      have been returned by the title company or anyone examining title to the
      premises, and if it appears from such objections or exceptions, that time
      will be required within which to remove the same, then and in that event,
      Sellers shall have reasonable adjournment or adjournments, from time to
      time, within which to clear such objections or exceptions.

23.   This agreement shall be considered only an offer on the part of the Buyers
      and shall not be enforceable as against the Seller until executed by the
      Seller.

            IN WITNESS WHEREOF, the parties hereto have duly executed this Rider
on the day and year written below.

Mendam, New Jersey 07945
    
Dear Paul:
    
We are pleased to confirm the terms of your ongoing employment with Schein
Pharmaceutical, Inc. (the "Company") as Vice President of Business Development.
    
1.   The Company will employ you as Vice President of Business Development for
the period from the date of this Agreement and continuing until 60 days after
either you or the Company gives written notice to the other that you or it does
not wish to continue your employment hereunder (a "Non-Continuation Notice").
You accept such employment, and will devote your full time and effort to the
business and affairs of the Company, with such duties consistent with your
position as may be assigned to you from time to time by the President (or such
other officer) or Board of Directors of the Company.

2.   In consideration of all services rendered by you during your employment
hereunder, the Company will pay you a base salary at the annual rate of
$180,000, payable in accordance with the Company's payroll practices from time
to time in effect. The Company will review your salary at least once each year
and may in its discretion increase your salary.

3.   For as long as you are employed by the Company you will be entitled to
participate in all bonus, incentive, retirement, profit-sharing, life, medical,
disability and other benefit plans and programs of the Company as are from time
to time generally available to other executives of the Company with comparable
responsibilities, subject to the provisions of those programs.

4.   Your employment by the Company: (a) shall terminate upon your death; (b)
shall terminate 60 days after a Non-Continuation Notice is given; (c) may be
terminated by the Company for cause at any time; and (d) may be terminated by
the Company if you fail to render the services provided for in this Agreement
for a continuous period of six months by reason of physical or mental illness or
disability.

     For purposes of this Agreement, "cause" means (i) your willful and
continued failure substantially to perform your duties with the Company, (ii)
fraud, misappropriation or intentional material damage to the property or
business of the Company or (iii) commission of a felony.
    
5.   If your employment is terminated by the Company's giving a Non-Continuation
<PAGE>
 
Notice as provided in Section 1 hereof (the giving of such Notice being a
"Termination Event"), the Company will pay you, in full satisfaction of all of
its obligations hereunder (except for its obligations under paragraphs 6 and 8
hereof), 100% of the amount of compensation (base salary and annual cash bonus)
paid (or payable) by the Company to you in respect of the last full fiscal year
of the Company immediately preceding the date of termination (the "Termination
Payment"). If the Termination Event occurs at any time within two years after a
Significant Date, the Termination Payment will be two times the amount provided
in the preceding sentence reduced by the amount of all compensation actually
paid to you by the Company at any time after the sixth-month anniversary of a
Significant Date; provided that in no event will the Termination Payment be less
than 100% of your compensation for the last full fiscal year preceding
termination, as provided in the preceding sentence. Notwithstanding anything to
the contrary in this Agreement, the maximum amount payable under this Section 5
shall be limited to that amount which when added to all other payments (or the
value of all other benefits) that are "contingent on a change in control" (as
such term is defined in the Internal Revenue Code of 1986, as amended (the
"Code") of the Company, would not constitute a "parachute payment" (as such term
is defined in the Code). The Termination Payment will be paid in a lump sum and
will be subject to any applicable payroll or other taxes required to be
withheld.
    
     Termination of your employment by the Company for any reason other than for
cause or disability, or your voluntary termination of employment on account of 
(i) a 10% or more reduction of your base salary by the Company or (ii) the
Company's assigning you duties or responsibilities that are inconsistent, in any
significant respect, with the scope of duties or responsibilities associated
with Vice President of Business Development or (iii) relocation of your office
other than to a facility which, as of the date of this Agreement, the Company or
any of its subsidiaries conducts operations, will be deemed a Termination Event.

     The Termination Payment will not be subject to offset on account of any
remuneration paid or payable to you for any subsequent employment you may
obtain, whether during or after the period during which the Termination Payment
is made and you shall have no obligation whatever to seek any subsequent
employment.
    
     For purposes of this Agreement, a "Significant Date" means the date on
which the persons (or successors designated by such persons or successors)
presently entitled to elect a majority of the Board of Directors of the company
(the "Parent") controlling the Company, are no longer entitled to elect,
directly or indirectly, a majority of the Board of Directors of the Company,
other than as an immediate result of public sales of stock of the Parent or the
Company; provided however that a Significant Date shall not be deemed to have
occurred if on such date the present Chairman of the Company (including
successors designated by such Chairman or by successors) alone or pursuant to
joint authority with others, are entitled to so elect.

6.   For one year following a Termination Event, the Company will also provide
you
<PAGE>
 
with basic health and medical benefits on the terms that such benefits are
provided to all salaried employees of the Company as of the date of your
termination of employment. If the Termination Event occurs at any time within
two years after a Significant Date, the Company will provide the benefits
described in the preceding sentence until the later of (A) the first anniversary
of the Termination Event and (B) the second anniversary of the Significant Date.
These benefits will cease immediately upon your obtaining other full-time
employment. If the Company is unable to provide any of the foregoing benefits
under then existing plans without costs it considers excessive, the Company will
be entitled to satisfy any such obligation by making a payment to you equal to
two times the cost to the Company during the last full year immediately
preceding the Termination Event of providing such benefits to you.
    
7.   At the time you execute this Agreement, you will also execute and deliver
to the Company the enclosed Confidentiality Undertaking.

8.   The Company will reimburse you for reasonable attorneys fees and expenses
incurred by you if you are employed hereunder on a Significant Date and prevail
against the Company with respect to a claim hereunder arising on or after such
date.

9.   This Agreement shall be binding upon and inure to the benefit of you and
your legal representatives and the Company and any assignee or successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business or assets of the Company.

10.  This Agreement: contains the entire agreement between the parties with
respect to the subject matter hereof, may not be modified or terminated orally,
and shall be construed and governed in accordance with the laws of the State of
New York.

     If the foregoing is acceptable to you, please execute the enclosed copy of
this Agreement and return it to the undersigned.
   

Very truly yours,
    
SCHEIN PHARMACEUTICAL, INC.

Notice as provided in Section 1 hereof (the giving of such Notice being a
"Termination Event"), the Company will pay you, in full satisfaction of all of
its obligations hereunder (except for its obligations under paragraphs 6 and 8
hereof), 100% of the amount of compensation (base salary and annual cash bonus)
paid (or payable) by the Company to you in respect of the last full fiscal year
of the Company immediately preceding the date of termination (the "Termination
Payment"). If the Termination Event occurs at any time within two years after a
Significant Date, the Termination Payment will be two times the amount provided
in the preceding sentence reduced by the amount of all compensation actually
paid to you by the Company at any time after the sixth-month anniversary of a
Significant Date; provided that in no event will the Termination Payment be less
than 100% of your compensation for the last full fiscal year preceding
termination, as provided in the preceding sentence. Notwithstanding anything to
the contrary in this Agreement, the maximum amount payable under this Section 5
shall be limited to that amount which when added to all other payments (or the
value of all other benefits) that are "contingent on a change in control" (as
such term is defined in the Internal Revenue Code of 1986, as amended (the
"Code") of the Company, would not constitute a "parachute payment" (as such term
is defined in the Code). The Termination Payment will be paid in a lump sum and
will be subject to any applicable payroll or other taxes required to be
withheld.

     Termination of your employment by the Company for any reason other than for
cause or disability, or your voluntary termination of employment on account of
(i) a 10% or more reduction of your base salary by the Company or (ii) the
Company's assigning you duties or responsibilities that are inconsistent, in any
significant respect, with the scope of duties or responsibilities associated
with Vice President of Operations, Danbury Pharmacal, Inc., or (iii) relocation
of your office other than to a facility which, as of the date of this Agreement,
the Company or any of its subsidiaries conducts operations, will be deemed a
Termination Event.

     The Termination Payment will not be subject to offset on account of any
remuneration paid or payable to you for any subsequent employment you may
obtain, whether during or after the period during which the Termination Payment
is made and you shall have no obligation whatever to seek any subsequent
employment.

     For purposes of this Agreement, a "Significant Date" means the date on
which the persons (or successors designated by such persons or successors)
presently entitled to elect a majority of the Board of Directors of the company
(the "Parent") controlling the Company, are no longer entitled to elect,
directly or indirectly, a majority of the Board of Directors of the Company,
other than as an immediate result
<PAGE>
 
of public sales of stock of the Parent or the Company; provided however that a
Significant Date shall not be deemed to have occurred if on such date the
present Chairman of the Company (including successors designated by such
Chairman or by successors) alone or pursuant to joint authority with others, are
entitled to so elect.
    
6.   For one year following a Termination Event, the Company will also provide
you with basic health and medical benefits on the terms that such benefits are
provided to all salaried employees of the Company as of the date of your
termination of employment. If the Termination Event occurs at any time within
two years after a Significant Date, the Company will provide the benefits
described in the preceding sentence until the later of (A) the first anniversary
of the Termination Event and (B) the second anniversary of the Significant Date.
These benefits will cease immediately upon your obtaining other full-time
employment. If the Company is unable to provide any of the foregoing benefits
under then existing plans without costs it considers excessive, the Company will
be entitled to satisfy any such obligation by making a payment to you equal to
two times the cost to the Company during the last full year immediately
preceding the Termination Event of providing such benefits to you.
    
7.   At the time you execute this Agreement, you will also execute and deliver
to the Company the enclosed Confidentiality Undertaking.

8.   The Company will reimburse you for reasonable attorneys fees and expenses
incurred by you if you are employed hereunder on a Significant Date and prevail
against the Company with respect to a claim hereunder arising on or after such
date.

9.   This Agreement shall be binding upon and inure to the benefit of you and
your legal representatives and the Company and any assignee or successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business or assets of the Company.

10.  This Agreement: contains the entire agreement between the parties with
respect to the subject matter hereof, may not be modified or terminated orally,
and shall be construed and governed in accordance with the laws of the State of
New York.

further obligation to pay any amount under this agreement.

employment of the Employee, or on the Employee to remain in the employ of the
Company or any of its subsidiaries, subject, however, to the provisions of any
other agreement between the Company or any of its subsidiaries and the Employee.

                        DEFERRED COMPENSATION AGREEMENT
    
                            Dated November 22, 1993

          The parties to this agreement are Schein Pharmaceutical, Inc. (the
"Company") and Jay Cayado (the "Employee").
               ----------

          The Company and its subsidiaries wish to obtain the continuing benefit
of the Employee's services after an Equity Investor Transaction (as defined in

Investor Transaction by providing additional cash compensation to the Employee.

          The parties agree as follows:
    
          1.   Deferred Compensation. Subject to the provisions of this
               ---------------------
agreement, the Company shall pay the Employee a bonus of $250,000 (the "Deferred
                                                         --------

employee, not later than thirty days after the applicable anniversary date, an
amount equal to (a) 50% of the Deferred Compensation Amount after the second

Transaction, and (c) an additional 25% of the Deferred Compensation Amount after
the fourth anniversary of an Equity Investor Transaction, provided the Employee
is in the employ of the Company or any of its subsidiaries at each such
anniversary date. Notwithstanding the foregoing, however, if the Employee's
employment with the Company and each of its subsidiaries terminates at any time
before the Final Date,

                                       1

the amount, if any, payable to the Employee, and the time any such amount shall
be payable, shall be determined under section 2 of this agreement. As used in
this agreement, (a) the term "Final Date" means the fourth anniversary of the
consummation of the Equity Investor Transaction, and (b) the term "Equity
Investor Transaction" means a transaction (or series of transactions) resulting
in the stockholders (or beneficiaries of any such stockholders which are trusts)
of Schein Holdings, Inc., a New York corporation of which SPINC is a subsidiary,
receiving after November 1, 1993 and prior to December 31, 1994 not less than
$200 million in the aggregate in respect of the disposition of shares of Schein
Holdings, Inc., by cash dividend or otherwise. All payments under this agreement
shall be subject to applicable federal, state and local withholdings.
    
          2.   Termination of Employment.

termination for Cause (as defined in section 2.2) or voluntary termination in
accordance with section 2.3, the Company shall pay the Employee (or his or her
estate), not later than thirty days following the termination of employment, the
Deferred Compensation Amount. As used in this agreement, the term "Disability"
means a permanent disability, as determined by the board of directors of the
Company in its sole discretion. A Disability shall be deemed to occur at the
time of that determination by the board of directors.
    
               2.2  Cause. If the Company or any of its subsidiaries terminates
                    -----
the Employee's employment for Cause, or the Employee terminates his or her
employment in
    
                                       2
<PAGE>
 
violation of an agreement with the Company or any of its subsidiaries, or if it
is discovered after such termination of employment that the Employee had engaged
in conduct that would have justified termination if employment for Cause, the

in this agreement, termination of employment for "Cause" means (a) the
Employee's wilful and continued failure substantially to perform his or her
duties with the Company and its subsidiaries, (b) fraud, misappropriation or
intentional material damage to the property or business of the Company or any of
its subsidiaries or (c) commission of a felony.
    
               2.3  Voluntary Termination.  If the Employee voluntarily
                    ---------------------
terminates his or her employment with the Company and each of its subsidiaries
before the second anniversary of an Equity Investor Transaction, the Company
shall have no obligation to pay any amount under this agreement. If the Employee
voluntarily terminates his or her employment with the Company and each of its
subsidiaries thereafter, the Company shall pay the Employee, not later than
thirty days after the applicable anniversary date, an amount equal to (a) 50% of
the Deferred Compensation Amount if the termination of employment occurs after
the second anniversary, but before the third anniversary, of the consummation of
an Equity Investor Transaction, (b) an additional 25% of the Deferred
Compensation Amount if the termination of employment occurs after the third
anniversary of the consummation of an Equity Investor Transaction, but before

                (b) Payroll deductions for a participant shall commence on the

deductions made on each payday during the time he or she is a participant at

during the Offering Period, and the aggregate of such payroll deductions during

Compensation during said Offering Period.
         
                (b) All payroll deductions made for a participant shall be

additional cash payments into such account.
        
                (c) A participant may discontinue his or her participation in
the Plan as provided in Section 10 hereof, or may increase or decrease the rate
of his or her payroll deductions during the Offering Period by filing with
the Company a new subscription agreement authorizing a change in payroll
deduction rate. The Board may, in its discretion, limit the number of
participation rate changes. The change in rate shall be effective with the first
full payroll period following five (5) business days after the Company's receipt
of the new subscription agreement unless the Company elects to process a given
change in participation more quickly. A participant's subscription agreement
shall remain in effect unless terminated as provided in Section 10 hereof.
        
                (d) At the time the stock is purchased by a participant under

the Plan is disposed of, the participant must make adequate provision for the
Company's federal, state, or other tax withholding obligations, if any, which
arise upon the purchase or the disposition of the Common Stock. At any time,
the Company may, but will not be obligated to, withhold from the participant's
Compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.
        
                (e) Notwithstanding the foregoing, to the extent necessary to
comply with Section 423 (b)(8) of the Code and Section 3(b) hereof, a
participant's payroll
        

                                      -6-

deductions may be decreased to zero percent (0%) at such time during any
Offering Period which is scheduled to end during the current calendar year (the
"Current Offering Period") that the aggregate of all payroll deductions which
were previously used to purchase stock under the Plan in a prior Offering
Period which ended during that calendar year plus all payroll deductions
accumulated with respect to the Current Offering Period equal $25,000. Payroll
deductions shall recommence at the rate provided in such participant's
subscription agreement at the beginning of the first Offering Period which is
scheduled to end in the following calendar year, unless terminated by the
participant as provided in Section 10 hereof.
        
                7. Grant of Option. On the Enrollment Date of each Offering
                   ---------------
Period, each eligible Employee participating in such Offering Period shall be
granted an option to purchase on the Exercise Date of such Offering Period (at
the applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's  account as of the
Exercise Date by the applicable Purchase Price; provided that in no event shall
an Employee be permitted to purchase during each Offering Period more than a
number of Shares determined by dividing $25,000 by the Fair Market Value of a
share of the Company's  Common Stock on the Enrollment Date, and provided
further that such purchase shall be subject to the limitations set forth in
sections 3(b) and 12 hereof. Exercise of the option shall occur as provided in
Section 8 hereof, unless the participant has withdrawn pursuant to Section 10
hereof,QS and the option shall expire at the end of the day on the last day of
the Offering Period.
        
                8. Exercise of Option. A participant's option for the purchase
                   ------------------
shares will be exercised automatically on the Exercise Date, and the maximum
number of shares, including fractional shares, subject to option shall be
purchased for such participant at the applicable Purchase Price with the
accumulated payroll deductions in his or her account. During a participant's
lifetime, a participant's
        

                                      -7-
<PAGE>
 
option to purchase shares hereunder is exercisable only by him or her.
         
                9. Reports. A book-entry system of shares will be maintained for

not be issued except as in accordance with Section 10 hereof. Individual
accounts will be maintained for each participant in the Plan. Statements of
account will be given to participating Employees at least annually, which
statements will set forth the amounts of payroll deductions, the Purchase Price,
the number of shares purchased and the remaining cash balance, if any. The
Company will comply with all applicable reporting requirements applicable to
Employee Stock Purchase Plans under the Code.
         
               10. Withdrawal; Termination of Employment.

               (a) A participant may withdraw from the Plan at any time by
giving written notice to the Company in the form of Exhibit to this Plan. Upon
a participant's withdrawal from the Plan all the payroll deductions credited to
his or her account and not yet used to exercise his or her option under the Plan
will be automatically exercised on the next Exercise Date. No further payroll
deductions for the purchase of Common Stock will be made after receipt of the
notice of withdrawal. If a participant withdraws from the Plan, he or she must
wait one full Offering Period before resuming participation in the Plan. In
addition such participant must deliver a new subscription agreement to the
Company which will become effective on the Enrollment Date of the applicable
Offering Period.
        
               (b) upon a participant's ceasing to be an Employee for any 
reason, he will be deemed to have elected to withdraw from the Plan and the
payroll deductions credited to such participant's account during the applicable
Offering Period will be returned to such participant or, in the case of his
death, to the person entitled thereto under Section 14 hereof, and such
participant's right to purchase Common Stock will be automatically terminated. A
participant ceasing to be an Employee will have ninety (90) days to
        

                                      -8-

either sell their shares purchased or have certificates representing such shares
issued, provided, however, that in the case of death, the person designated as
beneficiary pursuant to Section 14 hereof shall have one (1) year to notify the
Company regarding disposition of the account. If the Company has not been
notified by such Employee within ninety (90) days, or such designated
beneficiary within one (1) year, certificates will be issued for full shares and
partial shares will be sold. All certificates shall bear a legend indicating
that such shares were issued pursuant to the Company's Employee Stock Purchase
Plan
         
               11. Interest. No interest shall accrue on the payroll deductions
                   --------

               12. Stock.

               (a) The maximum number of shares of the Company's Common Stock
which shall be made available for purchase under the Plan shall be 500,000,
subject to adjustment upon changes in capitalization of the Company as provided
in Section 18 hereof. If, on a given Exercise Date, the number of shares to be
purchased by participants exceeds the number of shares then available under the
Plan, the Company shall make a pro rata allocation of the shares remaining
available for purchase in as uniform a manner as shall be practicable and as it
shall determine to be equitable.
        
               (b) The participant will have no interest or voting right in
shares of Common Stock covered by his right to purchase until such Common Stock
has been purchased.
        
               (c) Shares to be delivered to a participant under the Plan will
be registered in the name of the participant or in the name of the participant

event that Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), or any successor provision ("Rule 16b-3") provides
specific requirements for the administrators of plans of this type, the Plan
shall be administered only by such a body and in such a manner as shall comply
with the applicable requirements of Rule 16b-3. Unless permitted by Rule 16b-3,
no discretion concerning decisions regarding the Plan shall be afforded to any
committee or persons that is not "disinterested" as that term is used in Rule
16b-3.
                14. Designation of Beneficiary.

beneficiary who is to receive any shares

                                      -10-

and cash, if any, form the participant's account under the Plan in the event of
such participant's death.
         
                (b) Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under the
Plan who is living at the time of such participant's death, the Company shall
deliver such shares and/or cash to the executor or administrator of the estate
of the participant, or if no such executor or administrator has been appointed
(to the knowledge of the Company), the Company, in its discretion, may deliver
such shares and/or cash to the spouse or to any one or more dependents or
relatives of the participant, or if no spouse, dependent or relative is known to
the Company, then to such other person as the Company may designate.

to receive shares under the Plan may be assigned, transferred, pledged or
otherwise deposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 14 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat each act as an election to withdrew
funds from an Offering Period in accordance with Section 10 hereof.
        
                16. Use of Funds. All payroll deductions received or held by 
                    ------------

Plan which has not yet been exercised shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of shares of Common Stock effected without receipt of consideration by
the Company; provided, however, that conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration." Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive. Except as expressly
provided herein, no issuance by the Company of, shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to a right of purchase under the Plan.
        
                (b) Liquidation, Merger or Asset Sale. In the event of the
                    ---------------------------------
dissolution or liquidation of the Company or a proposed sale of all or
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each right to purchase Common Stock under the
Plan shall be assumed or an equivalent right to purchase stock shall be
substituted by such successor corporation or a parent or subsidiary of such
Successor corporation, unless the Board determines, in the exercise of its sole
discretion and in lieu of such assumption or substitution, to set a new
Exercise Date (the "New Exercise Date"). If the Board sets a New Exercise Date,
the Board shall notify each participant in writing, at least ten (10) business
days prior to the New Exercise Date, that the Exercise Date has been changed to
the New Exercise Date and that his right to purchase Common Stock will be
exercised automatically on the New Exercise Date, unless prior to such date he
has withdrawn from the Plan as provided in Section 10 hereof.

require the person exercising such option to represent and warrant at the time
of any such exercise that the shares are being purchased only for investment
and without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of the law. In addition, any person

restrictions as may be required by Rule 16b-3 to qualify for the maximum
exemption from Section 16 of the Exchange Act with respect to Plan transactions.

fractional percentages are permitted.)
             
        3. I understand that said payroll deductions shall be accumulated for
the purchase of shares of Common Stock at the applicable Purchase Price
determined in accordance with the Employee Stock Purchase Plan. I understand
that all accumulated payroll deductions will be used to automatically purchase
shares of Common Stock, provided, however, that all accumulated payroll
deductions during the Offering Period of an Employee's termination will be
refunded.

to the Plan within two (2) years after the applicable Enrollment Date (the date
on which the right to purchase shares of Common Stock was granted) or one (1)
year after the Exercise Date, I will be treated for Federal income tax purposes
as having received ordinary income at the time of such disposition in the amount
equal to the excess of the fair market value of the shares at the time such
shares were purchased over the price which I paid for the shares. I hereby agree
to notify the Company in writing within thirty (30) days after the date of any 
disposition of my shares and I will make adequate provision for Federal, State
or other tax withholding obligations, if any, which arise upon the disposition
of the Common Stock. The Company may, but will not be obligated to, withhold
from my Compensation the amount necessary to meet any applicable withholding
obligation including any withholding necessary to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by me. If I dispose of such shares at any time after the expiration
of the 2-year and 1-year holding periods, I understand that I will be treated
for Federal income tax purposes as having received income only at the time of
such disposition, and that such income will be taxed as ordinary income only to
the extent of any amount equal to the lesser of (1) the excess of the fair
market value of the shares at the time of such disposition over the purchase
price which I paid for the shares, or (2) fifteen percent (15% ) of the fair
market value of the shares on the first day of the applicable Enrollment Date.

        FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER
 
  1. DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES; GUARANTEED DELIVERY
PROCEDURES. This Letter of Transmittal is to be completed either if (a)
Certificates are to be forwarded herewith or (b) tenders are to be made
pursuant to the procedures for tender by book-entry transfer set forth in "The

facsimile thereof), properly completed and duly executed, with any required
signature guarantees, and any other documents required by this Letter of
Transmittal, must be received by the Exchange Agent at its address set forth
herein on or prior to the Expiration Date. Old Notes may be tendered in whole
or in part in integral multiples of $1,000.
 
  Holders who wish to tender their Old Notes and (i) whose Old Notes are not
immediately available or (ii) who cannot deliver their Old Notes, this Letter
of Transmittal and all other required documents to the Exchange Agent on or
prior to the Expiration Date or (iii) who cannot complete the procedures for
delivery by book-entry transfer on a timely basis, may tender their Old Notes
by properly completing and duly executing a Notice of Guaranteed Delivery

Offer--Procedures for Tendering" in the Prospectus. Pursuant to such
procedures: (i) such tender must be made by or through an Eligible Institution
(as defined below); (ii) a properly completed and duly executed Notice of
Guaranteed Delivery, substantially in the form made available by the Company,
must be received by the Exchange Agent on or prior to the Expiration Date; and

together with a Letter of Transmittal (or facsimile thereof), properly
completed and duly executed, with any required signature guarantees and any
other documents required by this Letter of Transmittal, must be received by
the Exchange Agent within five New York Stock Exchange, Inc. trading days
after the date of execution of such Notice of Guaranteed Delivery, all as
provided in "The Exchange Offer--Procedures for Tendering" in the Prospectus.
 
  The Notice of Guaranteed Delivery may be delivered by hand or transmitted by
facsimile or mail to the Exchange Agent, and must include a guarantee by an
Eligible Institution in the form set forth in such Notice. For Old Notes to be
properly tendered pursuant to the guaranteed delivery procedure, the Exchange
Agent must receive a Notice of Guaranteed Delivery on or prior to the
Expiration Date. As used herein and in the Prospectus, "Eligible Institution"
means a firm or other entity identified in Rule 17Ad-15 under the Exchange Act
as "an eligible guarantor institution," including (as such terms are defined
therein) (i) a bank; (ii) a broker, dealer, municipal securities broker or
dealer or government securities broker or dealer; (iii) a credit union; (v) a
national securities exchange, registered securities association or clearing
agency; or (v) a savings association that is a participant in a Securities
Transfer Association.
 
  THE METHOD OF DELIVERY OF CERTIFICATES, THIS LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING
HOLDER AND THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE
EXCHANGE AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT
REQUESTED, PROPERLY INSURED, OR OVERNIGHT DELIVERY SERVICE IS RECOMMENDED. IN
ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.
 
  The Company will not accept any alternative, conditional or contingent
tenders. Each tendering holder, by execution of a Letter of Transmittal (or
facsimile thereof,) waives any right to receive any notice of the acceptance
of such tender.
 
  2. GUARANTEE OF SIGNATURES. No signature guarantee on this Letter of
Transmittal is required if:
 
    (i) this Letter of Transmittal is signed by the registered holder (which
  term, for purposes of this document, shall include any participant in DTC
  whose name appears on the register of holders maintained by the Trust as
  the owner of the Old Notes) of Old Notes tendered herewith, unless such
  holder(s) has completed either the box entitled "Special Issuance
  Instructions" or the box entitled "Special Delivery Instructions" above, or
 
    (ii) such Old Notes are tendered for the account of a firm that is an
  Eligible Institution.
 
                                       7
<PAGE>
 
  In all other cases, an Eligible Institution must guarantee the signature(s)
on this Letter of Transmittal. See Instruction 5.
 
  3. INADEQUATE SPACE. If the space provided in the box captioned "Description
of Old Notes" is inadequate, the Certificate number(s) and/or the principal
amount of Old Notes and any other required information should be listed on a
separate signed schedule which is attached to this Letter of Transmittal.
 
  4. PARTIAL TENDERS AND WITHDRAWAL RIGHTS. Tenders of Old Notes will be
accepted only in integral multiples of $1,000. If less than all the Old Notes
evidenced by any Certificate submitted are to be tendered, fill in the
principal amount of Old Notes which are to be tendered in the box entitled
"Aggregate Principal Amount of Old Notes Tendered (if less than all)." In such
case, new Certificate(s) for the remainder of the Old Notes that were
evidenced by your old Certificate(s) will only be sent to the holder of the
Old Notes, promptly after the Expiration Date. All Old Notes represented by
Certificates delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise indicated.
 
  Except as otherwise provided herein, tenders of Old Notes may be withdrawn
at any time on or prior to the Expiration Date. In order for a withdrawal to
be effective on or prior to that time, a written, telegraphic, telex or
facsimile transmission of such notice of withdrawal must be timely received by
the Exchange Agent at one of its addresses set forth above or in the
Prospectus on or prior to the Expiration Date. Any such notice of withdrawal
must specify the name of the person who tendered the Old Notes to be
withdrawn, the aggregate principal amount of Old Notes to be withdrawn, and
(if Certificates for Old Notes have been tendered) the name of the registered
holder of the Old Notes as set forth on the Certificate for the Old Notes, if
different from that of the person who tendered such Old Notes. If Certificates
for the Old Notes have been delivered or otherwise identified to the Exchange
Agent, then prior to the physical release of such Certificates for the Old
Notes, the tendering holder must submit the serial numbers shown on the
particular Certificates for the Old Notes to be withdrawn and the signature on
the notice of withdrawal must be guaranteed by an Eligible Institution, except
in the case of Old Notes tendered for the account of an Eligible Institution.
If Old Notes have been tendered pursuant to the procedures for book-entry
transfer set forth in the Prospectus under "The Exchange Offer--Procedures for
Tendering," the notice of withdrawal must specify the name and number of the
account at DTC to be credited with the withdrawal of Old Notes, in which case
a notice of withdrawal will be effective if delivered to the Exchange Agent by
written, telegraphic, telex or facsimile transmission. Withdrawals of tenders
of Old Notes may not be rescinded. Old Notes properly withdrawn will not be
deemed validly tendered for purposes of the Exchange Offer, but may be
retendered at any subsequent time on or prior to the Expiration Date by
following any of the procedures described in the Prospectus under "The
Exchange Offer--Procedures for Tendering."
 
  All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Company, in its
sole discretion, whose determination shall be final and binding on all
parties. Neither the Company nor the Exchange Agent or any other person shall
be under any duty to give any notification of any irregularities in any notice
of withdrawal or incur any liability for failure to give any such
notification. Any Old Notes which have been tendered but which are withdrawn
will be returned to the holder thereof without cost to such holder promptly
after withdrawal.
 
  5. SIGNATURES ON LETTER OF TRANSMITTAL, ASSIGNMENTS AND ENDORSEMENTS. If
this Letter of Transmittal is signed by the registered holder(s) of the Old
Notes tendered hereby, the signature(s) must correspond exactly with the
name(s) as written on the face of the Certificate(s) without alteration,
enlargement or any change whatsoever.
 
  If any of the Old Notes tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.
 
  If any, tendered Old Notes are registered in different name(s) on several
Certificates, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal (or facsimiles thereof) as there are different
registrations of Certificates.
 
  If this Letter of Transmittal or any Certificates or bond powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity,
such persons
 
                                       8
<PAGE>
 
should so indicate when signing and must submit proper evidence satisfactory
to the Company, in its sole discretion, of each such person's authority so to
act.
 
  When this Letter of Transmittal is signed by the registered owner(s) of the
Old Notes listed and transmitted hereby, no endorsement(s) of Certificate(s)
or separate bond power(s) are required unless New Notes are to be issued in
the name of a person other than the registered holder(s). Signature(s) on such
Certificate(s) or bond power(s) must be guaranteed by an Eligible Institution.
 
  If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the Old Notes listed, the Certificates must be endorsed
or accompanied by appropriate bond powers, signed exactly as the name or names
of the registered owner(s) appear(s) on the Certificates, and also must be
accompanied by such opinions of counsel, certifications and other information
as the Company or the Trustee for the Old Notes may require in accordance with
the restrictions on transfer applicable to the Old Notes. Signatures on such
Certificates or bond powers must be guaranteed by an Eligible Institution.
 
  6. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS. If New Notes are to be issued
in the name of a person other than the signer of this Letter of Transmittal,
or if New Notes are to be sent to someone other than the signer of this Letter
of Transmittal or to an address other than that shown above, the appropriate
boxes on this Letter of Transmittal should be completed. Certificates for Old
Notes not exchanged will be returned by mail or, if tendered by book-entry
transfer, by crediting the account indicated above maintained at DTC. See
Instruction 4.
 
  7. IRREGULARITIES. The Company will determine, in its sole discretion, all
questions as to the form of documents, validity, eligibility (including time
of receipt) and acceptance for exchange of any tender of Old Notes, which
determination shall be final and binding on all parties the Company reserves
the absolute right to reject any and all tenders determined by either of them
not to be in proper form or the acceptance of which, or exchange for which,
may, in the view of counsel to the Company, be unlawful. The Company also
reserves the absolute right, subject to applicable law, to waive any of the
conditions of the Exchange Offer set forth in the Prospectus under "The
Exchange Offer--Conditions" or any conditions or irregularity in any tender of
Old Notes of any particular holder whether or not similar conditions or
irregularities are waived in the case of other holders. The Company's
interpretation of the terms and conditions of the Exchange Offer (including
this Letter of Transmittal and the instructions hereto) will be final and
binding. No tender of Old Notes will be deemed to have been validly made until
all irregularities with respect to such tender have been cured or waived. The
Company and the Exchange Agent, or any other person shall not be under any
duty to give notification of any irregularities in tenders or incur any
liability for failure to give such notification.
 
  8. QUESTIONS, REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES. Questions and
requests for assistance may be directed to the Exchange Agent at its address
and telephone number set forth on the front of this Letter of Transmittal.
Additional copies of the Prospectus, the Notice of Guaranteed Delivery and the
Letter of Transmittal may be obtained from the Exchange Agent or from your
broker, dealer, commercial bank, trust company or other nominee.
 
  9. 31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9. Under U.S. Federal income
tax law, a holder whose tendered Old Notes are accepted for exchange is
required to provide the Exchange Agent with such holder's correct taxpayer
identification number ("TIN") on Substitute Form W-9 below. If the Exchange
Agent is not provided with the correct TIN, the Internal Revenue Service (the
"IRS") may subject the holder or other payee to a $50 penalty. In addition,
payments to such holders or other payees with respect to Old Notes exchanged
pursuant to the Exchange Offer may be subject to 31% backup withholding.
 
  The box in Part 2 of the Substitute Form W-9 may be checked if the tendering
holder has not been issued a TIN and has applied for a TIN or intends to apply
for a TIN in the near future. If the box in Part 2 is checked, the holder or
other payee must also complete the Certificate of Awaiting Taxpayer
Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 2 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Exchange Agent will
withhold 31% of all payments made prior to the time a properly certified TIN
is provided to the Exchange Agent. The Exchange Agent will retain such amounts
withheld during the 60 day period following the date of the Substitute Form W-
9. If the holder furnishes the Exchange Agent with its TIN within 60 days
after
 
                                       9
<PAGE>
 
the date of the Substitute Form W-9, the amounts retained during the 60 day
period will be remitted to the holder and no further amounts shall be retained
or withheld from payments made to the holder thereafter. If, however, the
holder has not provided the Exchange Agent with its TIN within such 60 day
period, amounts withheld will be remitted to the IRS as backup withholding. In
addition, 31% of all payments made thereafter will be withheld and remitted to
the IRS until a correct TIN is provided.
 
  The holder is required to give the Exchange Agent the TIN (e.g., social
security number or employer identification number) of the registered owner of
the Old Notes or of the last transferee appearing on the transfers attached
to, or endorsed on, the Old Notes. If the Old Notes are registered in more
than one name or are not in the name of the actual number, consult the
enclosed "Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9" for additional guidance on which number to report.
 
  Certain holders (including, among others, corporations, financial
institutions and certain foreign persons) may not be subject to these backup
withholding and reporting requirements. Such holders should nevertheless
complete the attached Substitute Form W-9 below, and write "exempt" on the
face thereof, to avoid possible erroneous backup withholding. A foreign person
may qualify), as an exempt recipient by submitting a properly completed IRS
Form W-8, signed under penalties of perjury, attesting to that holder's exempt
status. Please consult the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional guidance on which
holders are exempt from backup withholding.
 
  Backup withholding is not an additional U.S. Federal income tax. Rather, the
U.S. Federal income tax liability of a person subject to backup withholding
will be reduced by the amount of tax withheld. If withholding results in an
overpayment of taxes, a refund may be obtained.
 
  10. WAIVER OF CONDITIONS. The Company reserves the absolute right to waive
satisfaction of any or all conditions enumerated in the Prospectus.
 
  11. NO CONDITIONAL TENDERS. No alternative, conditional, irregular or
contingent tenders will be accepted. All tendering holders of Old Notes, by
execution of this Letter of Transmittal, shall waive any right to receive
notice of the acceptance of their Old Notes for exchanges.
 
  Neither the Company, the Exchange Agent nor any other person is obligated to
give notice of any defect or irregularity with respect to any tender of Old
Notes nor shall any of them incur any liability for failure to give any such
notice.
 
  12. LOST, DESTROYED OR STOLEN CERTIFICATES. If any Certificate(s)
representing Old Notes have been lost, destroyed or stolen, the holder should
promptly notify the Exchange Agent. The holder will then be instructed as to
the steps that must be taken in order to replace the Certificate(s). This
Letter of Transmittal and related documents cannot be processed until the
procedures for replacing lost, destroyed or stolen Certificate(s) have been
followed.
 
  13. SECURITY TRANSFER TAXES. Holders who tender their Old Notes for exchange
will not be obligated to pay any transfer taxes in connection therewith. If,
however, New Notes are to be delivered to, or are to be issued in the name of,
any person other than the registered holder of the Old Notes tendered, or if a
transfer tax is imposed for any reason other than the exchange of Old Notes in
connection with the Exchange Offer, then the amount of any such transfer tax
(whether imposed on the registered holder or any other persons) will be
payable by the tendering holder. If satisfactory evidence of payment of such
taxes or exemption therefrom is not submitted with the Letter of Transmittal,
the amount of such transfer taxes will be billed directly to such tendering
holder.

  YOU MUST COMPLETE THE FOLLOWING CERTIFICATE IF YOU CHECKED THE BOX IN PART 2
OF SUBSTITUTE FORM W-9 CERTIFICATE OF AWAITING TAXPAYER IDENTIFICATION NUMBER
 
  I certify under penalties of perjury that a taxpayer identification number
has not been issued to me, and either (1) I have mailed or delivered an
application to receive a taxpayer identification number to the appropriate
Internal Revenue Service Center or Social Security Administration Office or
(2) I intend to mail or deliver an application in the near future. I
understand that if I do not provide a taxpayer identification number by the
time of payment, 31% of all payments made to me on account of the New Notes
shall be retained until I provide a taxpayer identification number to the

                           EXCHANGE AGENT AGREEMENT
 
The Bank of New York
Corporate Trust Trustee Administration
101 Barclay Street--21st Floor
New York, New York 10286
 
                                                                         , 1998
 
Ladies and Gentlemen:
 
  Schein Pharmaceutical, Inc. (the "Company") proposes to make an offer (the
"Exchange Offer") to exchange its Senior Floating Rate Notes due 2004 (the
"New Notes") which have been registered under the Securities Act of 1933, as
amended (the "Securities Act") for its Senior Floating Rate Notes due 2004
(the "Old Notes"). The terms and conditions of the Exchange Offer as currently
contemplated are set forth in a prospectus, dated      , 1998 (the
"Prospectus"), proposed to be distributed to all record holders of the Old
Notes. The Old Notes and the New Notes are collectively referred to herein as
the "Notes".
 
  The Company hereby appoints The Bank of New York to act as exchange agent
(the "Exchange Agent") in connection with the Exchange Offer. References
hereinafter to "you" shall refer to The Bank of New York.
 
  The Exchange Offer is expected to be commenced by the Company on or about
     , 1998. The Letter of Transmittal accompanying the Prospectus (or in the
case of book entry securities, the ATOP system) is to be used by the holders
of the Old Notes to accept the Exchange Offer and contains instructions with
respect to the delivery of certificates for Old Notes tendered in connection
therewith.
 
  The Exchange Offer shall expire at 5:00 P.M., New York City time, on      ,
1998 or on such later date or time to which the Company may extend the
Exchange Offer (the "Expiration Date"). Subject to the terms and conditions
set forth in the Prospectus, the Company expressly reserves the right to
extend the Exchange Offer from time to time and may extend the Exchange Offer
by press release or other public announcement prior to 9:00 A.M., New York
City time, on the business day following the previously scheduled Expiration
Date.
 
  The Company expressly reserves the right to amend or terminate the Exchange
Offer, and not to accept for exchange any Old Notes not theretofore accepted
for exchange, upon the occurrence of any of the conditions of the Exchange
Offer specified in the Prospectus under the caption "The Exchange Offer--
Conditions". The Company will give oral or written notice of any amendment,
termination or nonacceptance to you as promptly as practicable.
 
  In carrying out your duties as Exchange Agent, you are to act in accordance
with the following instructions:
 
  1. You will perform such duties and only such duties as are specifically set
forth in the section of the Prospectus captioned "The Exchange Offer" or as
specifically set forth herein; provided, however, that in no way will your
general duty to act in good faith be discharged by the foregoing.
 
  2. You will establish an account with respect to the Old Notes at The
Depository Trust Company (the "Book-Entry Transfer Facility") for purposes of
the Exchange Offer within two business days after the date of the Prospectus,
and any financial institution that is a participant in the Book-Entry Transfer
Facility's systems may make book-entry delivery of the Old Notes by causing
the Book-Entry Transfer Facility to transfer such Old Notes into your account
in accordance with the Book-Entry Transfer Facility's procedure for such
transfer.
 
  3. You are to examine each of the Letters of Transmittal and certificates
for Old Notes (or confirmation of book-entry transfer into your account at the
Book-Entry Transfer Facility) and any other documents delivered or mailed to
you by or for holders of the Old Notes to ascertain whether: (i) the Letters
of Transmittal and any such
<PAGE>
 
other documents are duly executed and properly completed in accordance with
instructions set forth therein and (ii) the Old Notes have otherwise been
properly tendered. In each case where the Letter of Transmittal or any other
document has been improperly completed or executed or any of the certificates
for Old Notes are not in proper form for transfer or some other irregularity
in connection with the acceptance of the Exchange Offer exists, you will
endeavor to inform the presenters of the need for fulfillment of all
requirements and to take any other action as may be necessary or advisable to
cause such irregularity to be corrected.
 
  4. With the approval of the President, Executive Vice President or Senior
Vice President of the Company (such approval, if given orally, to be confirmed
in writing) or any other party designated by such an officer in writing, you
are authorized to waive any irregularities in connection with any tender of
Old Notes pursuant to the Exchange Offer.
 
  5. Tenders of Old Notes may be made only as set forth in the Letter of
Transmittal and in the section of the Prospectus captioned "The Exchange
Offer--Procedures for Tendering", and Old Notes shall be considered properly
tendered to you only when tendered in accordance with the procedures set forth
therein.
 
  Notwithstanding the provisions of this paragraph 5, Old Notes which the
President, Executive Vice President or Senior Vice President of the Company
shall approve as having been properly tendered shall be considered to be
properly tendered (such approval, if given orally, shall be confirmed in
writing).
 
  6. You shall advise the Company with respect to any Old Notes received
subsequent to the Expiration Date and accept its instructions with respect to
disposition of such Old Notes.
 
  7. You shall accept tenders:
 
    (a) in cases where the Old Notes are registered in two or more names only
  if signed by all named holders;
 
    (b) in cases where the signing person (as indicated on the Letter of
  Transmittal) is acting in a fiduciary or a representative capacity only
  when proper evidence of his or her authority so to act is submitted; and
 
    (c) from persons other than the registered holder of Old Notes provided
  that customary transfer requirements, including any applicable transfer
  taxes, are fulfilled.
 
  You shall accept partial tenders of Old Notes where so indicated and as
permitted in the Letter of Transmittal and deliver certificates for Old Notes
to the transfer agent for split-up and return any untendered Old Notes to the
holder (or such other person as may be designated in the Letter of
Transmittal) as promptly as practicable after expiration or termination of the
Exchange Offer.
 
  8. Upon satisfaction or waiver of all of the conditions to the Exchange
Offer, the Company will notify you (such notice if given orally, to be
confirmed in writing) of its acceptance, promptly after the Expiration Date,
of all Old Notes properly tendered and you, on behalf of the Company, will
exchange such Old Notes for New Notes and cause such Old Notes to be
cancelled. Delivery of New Notes will be made on behalf of the Company by you
at the rate of $1,000 principal amount of New Notes for each $1,000 principal
amount of the Old Notes tendered promptly after notice (such notice if given
orally, to be confirmed in writing) of acceptance of said Old Notes by the
Company; provided, however, that in all cases, Old Notes tendered pursuant to
the Exchange Offer will be exchanged only after timely receipt by you of
certificates for such Old Notes (or confirmation of book-entry transfer into
your account at the Book-Entry Transfer Facility), a properly completed and
duly executed Letter of Transmittal (or facsimile thereof) with any required
signature guarantees and any other required documents. You shall issue New
Notes only in denominations of $1,000 or any integral multiple thereof.
 
  9. Tenders pursuant to the Exchange Offer are irrevocable, except that,
subject to the terms and upon the conditions set forth in the Prospectus and
the Letter of Transmittal, Old Notes tendered pursuant to the Exchange Offer
may be withdrawn at any time prior to the Expiration Date.
 
                                       2
<PAGE>
 
  10. The Company shall not be required to exchange any Old Notes tendered if
any of the conditions set forth in the Exchange Offer are not met. Notice of
any decision by the Company not to exchange any Old Notes tendered shall be
given (and confirmed in writing) by the Company to you.
 
  11. If, pursuant to the Exchange Offer, the Company does not accept for
exchange all or part of the Old Notes tendered because of an invalid tender,
the occurrence of certain other events set forth in the Prospectus under the
caption "The Exchange Offer--Conditions" or otherwise, you shall as soon as
practicable after the expiration or termination of the Exchange Offer return
those certificates for unaccepted Old Notes (or effect appropriate book-entry
transfer), together with any related required documents and the Letters of
Transmittal relating thereto that are in your possession, to the persons who
deposited them.
 
  12. All certificates for reissued Old Notes, unaccepted Old Notes or for New
Notes shall be forwarded by first-class mail.
 
  13. You are not authorized to pay or offer to pay any concessions,
commissions or solicitation fees to any broker, dealer, bank or other persons
or to engage or utilize any person to solicit tenders.
 
  14. As Exchange Agent hereunder you:
 
    (a) shall have no duties or obligations other than those specifically set
  forth herein or as may be subsequently agreed to in writing by you and the
  Company;
 
    (b) will be regarded as making no representations and having no
  responsibilities as to the validity, sufficiency, value or genuineness of
  any of the certificates or the Old Notes represented thereby deposited with
  you pursuant to the Exchange Offer, and will not be required to and will
  make no representation as to the validity, value or genuineness of the
  Exchange Offer;
 
    (c) shall not be obligated to take any legal action hereunder which might
  in your reasonable judgment involve any expense or liability, unless you
  shall have been furnished with reasonable indemnity;
 
    (d) may reasonably rely on and shall be protected in acting in reliance
  upon any certificate, instrument, opinion, notice, letter, telegram or
  other document or security delivered to you and reasonably believed by you
  to be genuine and to have been signed by the proper party or parties;
 
    (e) may reasonably act upon any tender, statement, request, comment,
  agreement or other instrument whatsoever not only as to its due execution
  and validity and effectiveness of its provisions, but also as to the truth
  and accuracy of any information contained therein, which you shall in good
  faith believe to be genuine or to have been signed or represented by a
  proper person or persons;
 
    (f) may rely on and shall be protected in acting upon written or oral
  instructions from any officer of the Company;
 
    (g) may consult with your counsel with respect to any questions relating
  to your duties and responsibilities and the advice or opinion of such
  counsel shall be full and complete authorization and protection in respect
  of any action taken, suffered or omitted to be taken by you hereunder in
  good faith and in accordance with the advice or opinion of such counsel;
  and
 
    (h) shall not advise any person tendering Old Notes pursuant to the
  Exchange Offer as to the wisdom of making such tender or as to the market
  value or decline or appreciation in market value of any Old Notes.
 
  15. You shall take such action as may from time to time be requested by the
Company or its counsel (and such other action as you may reasonably deem
appropriate) to furnish copies of the Prospectus, Letter of Transmittal and
the Notice of Guaranteed Delivery (as defined in the Prospectus) or such other
forms as may be approved from time to time by the Company, to all persons
requesting such documents and to accept and comply with telephone requests for
information relating to the Exchange Offer, provided that such information
shall relate only to the procedures for accepting (or withdrawing from) the
Exchange Offer. The Company will furnish you with copies of such documents at
your request. All other requests for information relating to the Exchange
Offer shall be directed to the Company, Attention: General Counsel.
 
                                       3
<PAGE>
 
  16. You shall advise by facsimile transmission or telephone, and promptly
thereafter confirm in writing to the General Counsel of the Company and such
other person or persons as it may request, daily (and more frequently during
the week immediately preceding the Expiration Date and if otherwise requested)
up to and including the Expiration Date, as to the number of Old Notes which
have been tendered pursuant to the Exchange Offer and the items received by
you pursuant to this Agreement, separately reporting and giving cumulative
totals as to items properly received and items improperly received. In
addition, you will also inform, and cooperate in making available to, the
Company or any such other person or persons upon oral request made from time
to time prior to the Expiration Date of such other information as it or he or
she reasonably requests. Such cooperation shall include, without limitation,
the granting by you to the Company and such person as the Company may request
of access to those persons on your staff who are responsible for receiving
tenders, in order to ensure that immediately prior to the Expiration Date the
Company shall have received information in sufficient detail to enable it to
decide whether to extend the Exchange Offer. You shall prepare a final list of
all persons whose tenders were accepted, the aggregate principal amount of Old
Notes tendered, the aggregate principal amount of Old Notes accepted and
deliver said list to the Company.
 
  17. Letters of Transmittal and Notices of Guaranteed Delivery shall be
stamped by you as to the date and the time of receipt thereof and shall be
preserved by you for a period of time at least equal to the period of time you
preserve other records pertaining to the transfer of Notes. You shall dispose
of unused Letters of Transmittal and other surplus materials by returning them
to the Company.
 
  18. You hereby expressly waive any lien, encumbrance or right of set-off
whatsoever that you may have with respect to funds deposited with you for the
payment of transfer taxes by reasons of amounts, if any, borrowed by the
Company, or any of its subsidiaries or affiliates pursuant to any loan or
credit agreement with you or for compensation owed to you hereunder.
 
  19. For services rendered as Exchange Agent hereunder, you shall be entitled
to such compensation as set forth on Schedule I attached hereto.
 
  20. You hereby acknowledge receipt of the Prospectus and the Letter of
Transmittal and further acknowledge that you have examined each of them. Any
inconsistency between this Agreement, on the one hand, and the Prospectus and
the Letter of Transmittal (as they may be amended from time to time), on the
other hand, shall be resolved in favor of the latter two documents, except
with respect to the duties, liabilities and indemnification of you as Exchange
Agent, which shall be controlled by this Agreement.
 
  21. The Company covenants and agrees to indemnify and hold you harmless in
your capacity as Exchange Agent hereunder against any loss, liability, cost or
expense, including attorneys' fees and expenses, arising out of or in
connection with any act, omission, delay or refusal made by you in reliance
upon any signature, endorsement, assignment, certificate, order, request,
notice, instruction or other instrument or document reasonably believed by you
to be valid, genuine and sufficient and in accepting any tender or effecting
any transfer of Old Notes reasonably believed by you in good faith to be
authorized, and in delaying or refusing in good faith to accept any tenders or
effect any transfer of Old Notes; provided, however, that the Company shall
not be liable for indemnification or otherwise for any loss, liability, cost
or expense to the extent arising out of your gross negligence or willful
misconduct. In no case shall the Company be liable under this indemnity with
respect to any claim against you unless the Company shall be notified by you,
by letter or by facsimile confirmed by letter, of the written assertion of a
claim against you or of any other action commenced against you, promptly after
you shall have received any such written assertion or notice of commencement
of action. The Company shall be entitled to participate at its own expense in
the defense of any such claim or other action, and, if the Company so elects,
the Company shall assume the defense of any suit brought to enforce any such
claim. In the event that the Company shall assume the defense of any such
suit, the Company shall not be liable for the fees and expenses of any
additional counsel thereafter retained by you so long as the Company shall
retain counsel satisfactory to you to defend such suit, and so long as you
have not determined, in your reasonable judgment, that a conflict of interest
exists between you and the Company.
 
                                       4
<PAGE>
 
  22. You shall arrange to comply with all requirements under the tax laws of
the United States, including those relating to missing Tax Identification
Numbers, and shall file any appropriate reports with the Internal Revenue
Service. The Company understands that you are required to deduct 31% on
payments to holders who have not supplied their correct Taxpayer
Identification Number or required certification. Such funds will be turned
over to the Internal Revenue Service in accordance with applicable
regulations.
 
  23. You shall deliver or cause to be delivered, in a timely manner to each
governmental authority to which any transfer taxes are payable in respect of
the exchange of Old Notes, the Company's check in the amount of all transfer
taxes so payable, and the Company shall reimburse you for the amount of any
and all transfer taxes payable in respect of the exchange of Old Notes;
provided, however, that you shall reimburse the Company for amounts refunded
to you in respect of your payment of any such transfer taxes, at such time as
such refund is received by you.
 
  24. This Agreement and your appointment as Exchange Agent hereunder shall be
construed and enforced in accordance with the laws of the State of New York
applicable to agreements made and to be performed entirely within such state,
and without regard to conflicts of law principles, and shall inure to the
benefit of, and the obligations created hereby shall be binding upon, the
