Item 1.  Changes in Control of Registrant

        (a) On April 30, 1998, Arizona Acquisition Corp., a Delaware
corporation ("AAC"), controlled by Cable Systems Holding, LLC, a Delaware
limited liability company ("CSH LLC"), and its affiliates (with CSH LLC, the
"CSH Affiliates"), merged with and into the Registrant, IPC Information Systems,
Inc., a Delaware corporation (the "Company") (the "Merger"), pursuant to the
Agreement and Plan of Merger, dated as of December 18, 1997, as amended and
restated on April 9, 1998 (the "Merger Agreement"), between AAC and the Company.

         Pursuant to the Merger, each share of the Company's common stock, par
value $0.01 per share ("Company Common Stock"), issued and outstanding
immediately prior to the effective time (the "Effective Time") of the Merger
(other than treasury shares, which were canceled) was converted, at the election
of the holder thereof into (i) either the right to receive $21.00 per share in
cash or (ii) the right to retain one fully paid and nonassessable share of
common stock of the surviving corporation (the "Surviving Corporation") (the
"Surviving Corporation Common Stock"). The Company's stockholders elected to
retain 1,203,870 shares of Surviving Corporation Common Stock (which included
the election of Richard P. Kleinknecht, the current Vice Chairman of the
Surviving Corporation, to retain 380,952 shares) which was less than the maximum
stock election number (1,752,381) and greater than the minumum stock election
number (380,952); therefore, proration was not required.

         Upon the Merger, the CSH Affiliates acquired 2,462,887 shares of
Surviving Corporation Common Stock in exchange for shares of common stock of AAC
for which the CSH Affiliates paid an aggregate of $51,720,627 in cash. Such
shares (representing 64.65% of the outstanding shares of Surviving Corporation
Common Stock upon the Merger) represent control of the Surviving Corporation.

         Pursuant to the Merger Agreement and the Amended and Restated Investors
Agreement (as defined below), the Company's Board of Directors approved a
resolution authorizing an increase in the number of directors constituting the
Board from six to nine. Upon the Merger, four directors (Peter J. Kleinknecht,
Theodore J. Johnson, Peter M. Stein and Robert J. McInerney) resigned from the
Board of Directors, and the remaining directors appointed the following six
designees of the CSH Shareholders (as defined in the Amended and Restated
Investors Agreement) to serve as directors of the Surviving Corporation: Richard
W. Smith and Kilin To, as independent directors, Richard M. Cashin, Jr., David
Y. Howe, Peter A. Woog and David Walsh. In addition, Robert J. McInerney, a
designee of the Kleinknecht Shareholders (as defined in the Amended and Restated
Investors Agreement), was appointed to serve as a director of the Surviving
Corporation.

         At the Effective Time, the Surviving Corporation entered into debt
financing arrangements, consisting of both Notes (as defined below) and a senior
secured revolving credit facility (the "Revolving Credit Facility"). The amount
invested by the CSH Affiliates plus the proceeds of the Notes were used to
finance the conversion into cash of the 9,536,665 shares of outstanding Company
Common Stock that were not retained by the Company's then-existing stockholders,
to


                                       -2-

<PAGE>



refinance a portion of the Company's outstanding indebtedness and to pay related
transaction fees and expenses. The Revolving Credit Facility is intended to be
available for the Company's working capital requirements following the Merger.

         The Surviving Corporation issued $247,400,000 aggregate principal
amount at maturity ($180,010,714 initial proceeds upon issuance) of 10 7/8%
Senior Discount Notes due May 1, 2008 (the "Notes"). Cash interest on the Notes
will be payable semiannually on May 1 and November 1 of each year commencing
November 1, 2001 at a rate of 10 7/8%. The Notes are unsubordinated, unsecured
indebtedness of the Surviving Corporation, ranking pari passu in right of
payment with all existing and future unsubordinated indebtedness of the
Surviving Corporation and senior in right of payment to all subordinated
indebtedness of the Surviving Corporation.

         On or after May 1, 2003, the Surviving Corporation may redeem the Notes
in whole or in part from time to time pursuant to the terms thereof. At any time
on or before May 1, 2001, the Surviving Corporation may redeem up to 35% of the
aggregate principal amount at maturity of the Notes with the proceeds of one or
more Equity Offerings (as defined in the Indenture, dated as of April 30, 1998
(the "Indenture"), between the Company and United States Trust Company of New
York, pursuant to which the Notes were issued) at 110.875% of their Accreted
Value (as defined in the Indenture) on the redemption date, provided that after
any such redemption, Notes representing at least 65% of the Notes originally
issued remain outstanding.

         Upon a Change of Control (as defined in the Indenture), the Surviving
Corporation will be required to make an offer to purchase the Notes at a
purchase price equal to 101% of their Accreted Value on the date of purchase
plus accrued interest, if any. In addition, a Change of Control would also
require the Surviving Corporation to repay outstanding indebtedness under the
Revolving Credit Facility.

         The Indenture restricts the ability of the Surviving Corporation and
its Restricted Subsidiaries (as defined in the Indenture), among other things,
to incur additional indebtedness, create liens, engage in sale-leaseback
transactions, pay dividends or make investments or certain other restricted
payments, sell assets, redeem capital stock, issue or sell stock of Restricted
Subsidiaries, enter into transactions with stockholders or affiliates or effect
a consolidation or merger.

         The Company, IPC Funding Corp. (a newly-formed subsidiary), Morgan 
Stanley Senior Funding, Inc. ("MSFF"), as syndication agent and arranger,
Goldman Sachs Credit Partners L.P., as documentation agent, General Electric
Capital Corporation, as collateral agent, and MSSF, as administrative agent,
entered into a Credit Agreement, dated as of April 30, 1998, pursuant to which
the Surviving Corporation was provided with $55 million of revolving credit
(subject to borrowing base and other limitations). The Revolving Credit Facility
included a $10 million sublimit for the issuance of letters of credit. Funds
from the Revolving Credit Facility were not needed in order to consummate the
Merger and the transactions contemplated thereby. The Revolving Credit Facility
will bear interest at a rate equal to, at the Surviving Corporation's option,
(i) the rate of interest announced publicly by Citibank, N.A. as its base rate
and (ii) a rate equal to 1/2 of 1% per annum above the weighted average of the
rates on overnight Federal funds

                                       -3-

<PAGE>



transactions with members of the Federal Reserve System arranged by Federal
funds brokers, as determined for any day by the administrative agent. The Base
Rate and LIBOR Rate will be subject to step-downs based on the leverage ratio of
the Surviving Corporation and its subsidiaries on a consolidated basis.

         The Revolving Credit Facility expires five years from the Effective
Time. The obligations of the Company under the Revolving Credit Facility are
secured by substantially all of the real and personal property of the Company
and its subsidiaries including inventory, accounts receivable
and the proceeds of the foregoing.

         The Revolving Credit Facility contains customary covenants of the
Surviving Corporation and its subsidiaries, including, without limitation,
restrictions in (i) asset dispositions, (ii) mergers or acquisitions, (iii)
capital expenditures, (iv) restricted payments, including prohibitions on the
payment of dividends to, or the repurchase or redemption of stock from,
stockholders, (v) the incurrence of indebtedness, (vi) loans and investments,
(vii) liens and (viii) transactions with affiliates (as defined in the Revolving
Credit Facility). Pursuant to the terms of the Revolving Credit Facility, the
Surviving Corporation would be in default under the Revolving Credit Facility
upon (i) the non-payment of principal or interest when due under the notes
issued in connection with the Revolving Credit Facility or, subject to
applicable grace periods in certain circumstances, upon the non-fulfillment of
the covenants described above, (ii) certain changes in control of the ownership
of the Company and (iii) various other events of default described in the
Revolving Credit Facility. If such an event of default occurs, the banks would
be entitled to take all actions permitted to be taken by a secured creditor
under the Uniform Commercial Code and to accelerate the amounts due under the
Revolving Credit Facility and may require all such amounts to be immediately
paid in full.

         Immediately following the Merger, the transactions contemplated by the
Share Exchange and Termination Agreement dated as of December 18, 1997 (the
"Agreement") among the Company, International Exchange Networks, Ltd. ("IXnet"),
David Walsh and Anthony Servidio were consummated. Pursuant to the Agreement,
Mr. Walsh and Mr. Servidio exchanged 336 shares and 224 shares, respectively, of
common stock, par value $0.01 per share, of IXnet (the "Exchange") for 131,047
and 87,365 shares, respectively, of Surviving Corporation Common Stock (net of
(i) 15,239 and 10,159 shares, respectively, which the Company held back pending
receipt of certain releases from former shareholders of IXnet and (ii) 6,095 and
4,063 shares, respectively, which were transferred to a former shareholder of
IXnet in satisfaction of a certain Installment Share Purchase Agreement). As a
result of these transactions, all ownership interests in Surviving Corporation
Common Stock were immediately diluted. Upon consummation of the Exchange,
Richard P. Kleinknecht and the CSH Affiliates owned approximately 9.43% and
60.99%, respectively, of the outstanding shares of Surviving Corporation Common
Stock.

         The Company, CSH LLC, Cable Systems International, Inc. ("CSI"),
Lawrence, Smith & Horey III, L.P. ("LSH"), Richard P. Kleinknecht, David Walsh
and Anthony Servidio entered into an Amended and Restated Investors Agreement
dated as of April 9, 1998 (the "Amended and Restated Investors Agreement"). The
Amended and Restated Investors Agreement provides for the addition of CSI and
LSH as parties thereto, but otherwise contains substantially the same terms

                                       -4-

and provisions as the Investors Agreement dated as of December 18, 1997 among
the Company, CSH LLC, Richard P. Kleinknecht, David Walsh and Anthony Servidio.

         The Surviving Corporation announced on May 1, 1998 its intent to
effect, in May, 1998, a 3 for 2 stock split by way of a stock dividend of one
share for every two shares outstanding. Surviving Corporation Common Stock is
now listed on the Nasdaq SmallCap Market under the symbol "IPCX."

         The Company issued a press release dated May 1, 1998 publicly

principal amount at maturity of the Company's 107/8% Senior Discount Notes due
2008 (the "Notes") issuable as provided in this Indenture. All things necessary
to make this Indenture a valid agreement of the Company, in accordance with its
terms, have been done, and the Company has done all things necessary to make the

Trustee hereunder and duly issued by the Company, valid obligations of the
Company as hereinafter provided.

          This Indenture is subject to, and shall be governed by, the provisions
of the Trust Indenture Act of 1939, as amended, that are required to be a part

proportionate benefit of all Holders, as follows.

        SECTION 2.01. Form and Dating. The Notes and the Trustee's certificate
of authentication shall be substantially in the form annexed hereto as Exhibit A
with such appropriate insertions, omissions, substitutions and other variations
as are required or permitted by this Indenture. The Notes may have notations,
legends or endorsements required by law, stock exchange agreements to which the
Company is subject or usage. The Company shall approve the form of the Notes and
any notation, legend or endorsement on the Notes. Each Note shall be dated the
date of its authentication.

        The terms and provisions contained in the form of the Notes annexed

"Global Notes"), deposited with, or on behalf of the Depositary, duly executed
by the Company and authenticated by the Trustee as hereinafter provided. Each

        SECTION 2.02. Execution, Authentication and Denominations. Subject to
Article Four and applicable law, the aggregate principal amount at maturity of
Notes which may be authenticated and delivered under this Indenture is
unlimited. The Notes shall be executed by an Officer of the Company. The

                                                             22



<PAGE>





        If an Officer whose signature is on a Note no longer holds that office
at the time the Trustee or authenticating agent authenticates the Note, the Note
shall be valid nevertheless.

        A Note shall not be valid until the Trustee or authenticating agent
manually signs the certificate of authentication on the Note. The signature
shall be conclusive evidence that the Note has been authenticated under this
Indenture.

        At any time and from time to time after the execution of this Indenture,
the Trustee or an authenticating agent shall upon receipt of a Company Order
authenticate for original issue Global Notes in the aggregate principal amount
at maturity specified in such Company Order; provided that the Trustee shall be
entitled to receive an Officers' Certificate and an Opinion of Counsel of the
Company in connection with such authentication of Notes. The Opinion of Counsel
shall, if requested by the Trustee, be to the effect that: (a) the form and
terms of such Notes have been established by or pursuant to a Board Resolution
or, if applicable, an indenture supplemental hereto in conformity with the
provisions of this Indenture; (b) such supplemental indenture, if any, when
executed and delivered by the Company and the Trustee, will constitute a valid
and binding obligation of the Company; (c) such Notes, when authenticated and
delivered by the Trustee and issued by the Company in the manner and subject to
any conditions specified in such Opinion of Counsel, will constitute valid and
binding obligations of the Company in accordance with their terms and will be
entitled to the benefits of this Indenture, subject to bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and similar laws of general
applicability relating to or affecting creditors' rights and to general
equitable principles; and (d) that the Company has been duly incorporated in,
and is a validly existing corporation in good standing under the laws of, the
State of Delaware. Such Company Order shall specify the amount of Global Notes
to be authenticated and the date on which the original issue of Notes is to be
authenticated and, in case of an issuance of Notes pursuant to Section 2.12,
shall certify that such issuance is in compliance with Article Four.

        The Trustee may appoint an authenticating agent to authenticate Notes.
An authenticating agent may authenticate Notes whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes
authentication by such authenticating agent. An authenticating agent has the
same rights as an Agent to deal with the Company or an Affiliate of the Company.

        The Notes shall be issuable only in registered form without coupons and
only in denominations of $1,000 in principal amount at maturity and any integral
multiple thereof.

        SECTION 2.03. Registrar and Paying Agent. The Company shall maintain an

demands to or upon the Company in respect of the

                                                             23



<PAGE>





Notes and this Indenture may be served, which shall be in the Borough of
Manhattan, The City of New York. The Company shall cause the Registrar to keep a
register of the Notes and of their transfer and exchange (the "Security
Register"). The Security Register shall be in written form or any other form
capable of being converted into written form within a reasonable time. The
Company may have one or more co-Registrars and one or more additional Paying
Agents.

        The Company shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture. The agreement shall implement the
provisions of this Indenture that relate to such Agent. The Company shall give
prompt written notice to the Trustee of the name and address of any such Agent
and any change in the address of such Agent. If the Company fails to maintain a
Registrar, Paying Agent and/or agent for service of notices and demands, the
Trustee shall act as such Registrar, Paying Agent and/or agent for service of
notices and demands. The Company may remove any Agent upon written notice to
such Agent and the Trustee; provided that no such removal shall become effective
until (i) the acceptance of an appointment by a successor Agent to such Agent as
evidenced by an appropriate agency agreement entered into by the Company and
such successor Agent and delivered to the Trustee or (ii) notification to the
Trustee that the Trustee shall serve as such Agent until the appointment of a
successor Agent in accordance with clause (i) of this proviso. The Company, any
Subsidiary of the Company, or any Affiliate of any of them may act as Paying
Agent, Registrar or co-Registrar, and/or agent for service of notice and
demands.

        The Company initially appoints the Trustee as Registrar, Paying Agent,
authenticating agent and agent for service of notice and demands. The Trustee
shall preserve in as current a form as is reasonably practicable the most recent
list available to it of the names and addresses of Holders and shall otherwise
comply with TIA ss. 312(a). If the Trustee is not the Registrar, the Company
shall furnish to the Trustee as of each Regular Record Date and at such other
times as the Trustee may reasonably request the names and addresses of Holders
as they appear in the Security Register, including the aggregate principal
amount at maturity of Notes held by each Holder.

        SECTION 2.04. Paying Agent to Hold Money in Trust. Not later than 11:00
a.m. (New York City time) on each due date of the principal, premium, if any,
and interest on any Notes, the Company shall deposit with the Paying Agent money
in immediately available funds sufficient to pay such principal, premium, if
any, and interest so becoming due. The Company shall require each Paying Agent
other than the Trustee to agree in writing that such Paying Agent shall hold in
trust for the benefit of the Holders or the Trustee all money held by the Paying
Agent for the payment of principal of, premium, if any, and interest on the
Notes (whether such money has been paid to it by the Company or any other
obligor on the Notes), and such Paying Agent shall promptly notify the Trustee
of any default by the Company (or any other obligor on the Notes) in making any
such payment. The Company at any time may require a Paying Agent to pay all
money held by it to the Trustee and account for any funds disbursed, and the
Trustee may at any

                                                             24



<PAGE>





time during the continuance of any payment default, upon written request to a
Paying Agent, require such Paying Agent to pay all money held by it to the
Trustee and to account for any funds disbursed. Upon doing so, the Paying Agent
shall have no further liability for the money so paid over to the Trustee. If
the Company or any Subsidiary of the Company or any Affiliate of any of them
acts as Paying Agent, it will, on or before each due date of any principal of,
premium, if any, or interest on the Notes, segregate and hold in a separate
trust fund for the benefit of the Holders a sum of money sufficient to pay such
principal, premium, if any, or interest so becoming due until such sum of money
shall be paid to such Holders or otherwise disposed of as provided in this
Indenture, and will promptly notify the Trustee of its action or failure to act.

        SECTION 2.05. Transfer and Exchange. When Notes are presented to the
Registrar or a co-Registrar with a request to register the transfer or to
exchange them for an equal principal amount at maturity of Notes of other
authorized denominations, the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transactions are met
(including that such Notes are duly endorsed or accompanied by a written
instrument of transfer in form satisfactory to the Trustee and Registrar duly
executed by the Holder thereof or by an attorney who is authorized in writing to
act on behalf of the Holder). To permit registrations of transfers and
exchanges, the Company shall execute and the Trustee shall authenticate Notes at
the Registrar's request. No service charge shall be made for any registration of
transfer or exchange or redemption of the Notes, but the Company may require
payment of a sum sufficient to cover any transfer tax or similar governmental
charge payable in connection therewith (other than any such transfer taxes or
other similar governmental charge payable upon exchanges pursuant to Section
2.08, 3.08 or 9.04).

        The Registrar shall not be required (i) to issue, register the transfer
of or exchange any Note during a period beginning at the opening of business 15
days before the day of the mailing of a notice of redemption of Notes selected
for redemption under Section 3.03 or Section 3.08 and ending at the close of
business on the day of such mailing, or (ii) to register the transfer of or
exchange any Note so selected for redemption in whole or in part, except the
unredeemed portion of any Note being redeemed in part.

        Notwithstanding any other provisions of this Section 2.05, unless and
until it is exchanged in whole or in part for Notes in definitive registered
form, the Global Notes representing all or a portion of the Notes may not be
transferred except as a whole by the Depositary to a nominee of such Depositary
or by a nominee of such Depositary to such Depositary or another nominee of such
Depositary or by such Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary.

        If the Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for the Global Notes or if at any time the Depositary
shall no longer be eligible under the next sentence of this paragraph, the
Company shall appoint a successor Depositary with respect

                                                             25



<PAGE>





to the Notes. Each Depositary appointed pursuant to this Section 2.05 must, at
the time of its appointment and at all times while it serves as Depositary, be a
clearing agency registered under the Exchange Act and any other applicable
statute or regulation. The Company will execute, and the Trustee, upon receipt
of an authentication order, will authenticate and deliver, Notes in definitive
registered form in any authorized denominations, in an aggregate principal
amount at maturity equal to the principal amount at maturity of the Global Note
or Notes representing such Notes in exchange for such Global Note or Notes if
(i) the Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for the Global Notes or if at any time the Depositary
shall no longer be eligible to serve as Depositary and a successor Depositary
for the Notes is not appointed by the Company within 60 days after the Company
receives such notice or becomes aware of such ineligibility or (ii) an Event of
Default has occurred and is continuing.

        The Company may at any time and in its sole discretion determine that
the Notes shall no longer be represented by a Global Note or Notes. In such
event the Company will execute, and the Trustee will, upon receipt of an
authentication order, authenticate and deliver, Notes in definitive registered
form in any authorized denominations, in an aggregate principal amount at
maturity equal to the principal amount at maturity of the Global Note or Notes
representing such Notes in exchange for such Global Note or Notes.

        Upon the exchange of a Global Note for Notes in definitive registered
form, without coupons, in authorized denominations, such Global Note shall be
canceled by the Trustee. Notes in definitive registered form issued in exchange
for a Global Note pursuant to this Section 2.05 shall be registered in such
names and in such authorized denominations as the Depositary for such Global
Note, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Trustee. The Trustee shall deliver such Notes to
or as directed by the Persons in whose names such Notes are so registered.

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

        SECTION 2.06. Replacement Notes. If a mutilated Note is surrendered to
the Trustee or if the Holder claims that the Note has been lost, destroyed or
wrongfully taken, then, in the absence of notice to the Company or the Trustee
that such Note has been acquired by a bona fide purchaser, the Company shall
issue and the Trustee shall authenticate a replacement Note of like tenor and
principal amount and bearing a number not contemporaneously outstanding;
provided that the requirements of this Section 2.06 are met. If required by the
Trustee or the Company, an indemnity bond must be furnished that is sufficient
in the judgment of both the Trustee and the Company to protect the Company, the
Trustee or any Agent from any loss that any of them may suffer if a Note is
replaced. The Company may charge such Holder for its expenses and the expenses
of the Trustee in replacing a Note. In case any such mutilated, lost, destroyed
or

                                                             26



<PAGE>





wrongfully taken Note has become or is about to become due and payable, the
Company in its discretion may pay such Note instead of issuing a new Note in
replacement thereof.

        Every replacement Note is an additional obligation of the Company and
shall be entitled to the benefits of this Indenture.

        SECTION 2.07. Outstanding Notes. Notes outstanding at any time are all
Notes that have been authenticated by the Trustee except for those canceled by
it, those delivered to it for cancellation and those described in this Section
2.07 as not outstanding.

        If a Note is replaced pursuant to Section 2.06, it ceases to be
outstanding unless and until the Trustee and the Company receive proof
satisfactory to them that the replaced Note is held by a bona fide purchaser.

        If the Paying Agent (other than the Company or an Affiliate of the
Company) holds on a maturity date money sufficient to pay Notes payable on that
date, then on and after that date such Notes cease to be outstanding and
interest on them shall cease to accrue.

               A Note does not cease to be outstanding because the Company or
one of its Affiliates holds such Note, provided, however, that in determining
whether the Holders of the requisite principal amount at maturity of the
outstanding Notes have given any request, demand, authorization, direction,
notice, consent or waiver hereunder, Notes owned by the Company or any other
obligor upon the Notes or any Affiliate of the Company or of such other obligor
shall be disregarded and deemed not to be outstanding, except that, in
determining whether the Trustee shall be protected in relying upon any such
request, demand, authorization, direction, notice, consent or waiver, only Notes
which the Trustee has actual knowledge to be so owned shall be so disregarded.
Notes 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 Notes and that the pledgee is not
the Company or any other obligor upon the Notes or any Affiliate of the Company
or of such other obligor.

        SECTION 2.08. Temporary Notes. Until definitive Notes are ready for
delivery, the Company may prepare and execute and the Trustee shall authenticate
temporary Notes. Temporary Notes shall be substantially in the form of
definitive Notes but may have insertions, substitutions, omissions and other
variations determined to be appropriate by the Officer executing the temporary
Notes, as evidenced by their execution of such temporary Notes. If temporary
Notes are issued, the Company will cause definitive Notes to be prepared without
unreasonable delay. After the preparation of definitive Notes, the temporary
Notes shall be exchangeable for definitive Notes upon surrender of the temporary
Notes at the office or agency of the Company designated for such purpose
pursuant to Section 4.02, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Notes the Company shall execute and
the

Trustee shall authenticate and deliver in exchange therefor a like principal
amount at maturity of definitive Notes of authorized denominations. Until so
exchanged, the temporary Notes shall be entitled to the same benefits under this
Indenture as definitive Notes.

        SECTION 2.09. Cancellation. The Company at any time may deliver to the
Trustee for cancellation any Notes previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may
deliver to the Trustee for cancellation any Notes previously authenticated
hereunder which the Company has not issued and sold. The Registrar and the
Paying Agent shall forward to the Trustee any Notes surrendered to them for
transfer, exchange or payment. The Trustee shall cancel all Notes surrendered
for transfer, exchange, payment or cancellation and shall destroy them in
accordance with its normal procedure.

        SECTION 2.10. CUSIP Numbers. The Company in issuing the Notes may use a
"CUSIP" number (if then generally in use), and the Company and the Trustee shall
use such CUSIP number, in notices of redemption or exchange as a convenience to
Holders; provided that any such notice shall state that no representation is
made as to the correctness of such number either as printed on the Notes or as
contained in any notice of redemption or exchange and that reliance may be
placed only on the other identification numbers printed on the Notes. The
Company shall promptly notify the Trustee of any change in "CUSIP", number for
the Notes.

        SECTION 2.11. Defaulted Interest. If the Company defaults in a payment
of interest on the Notes, it shall pay, or shall deposit with the Paying Agent
money in immediately available funds sufficient to pay, the defaulted interest,
plus (to the extent lawful) any interest payable on the defaulted interest, to
the Persons who are Holders on a subsequent special record date. A special
record date, as used in this Section 2.11 with respect to the payment of any
defaulted interest, shall mean the 15th day next preceding the date fixed by the
Company for the payment of defaulted interest, whether or not such day is a
Business Day. At least 15 days before the subsequent special record date, the
Company shall mail to each Holder and to the Trustee a notice that states the
subsequent special record date, the payment date and the amount of defaulted
interest to be paid.

        SECTION 2.12. Issuance of Additional Notes. The Company may, subject to
Article Four of this Indenture and applicable law, issue additional Notes under
this Indenture. The Notes issued on the Closing Date and any additional Notes
subsequently issued shall be treated as a single class for all purposes under
this Indenture.

                                  REDEMPTION

        SECTION 3.01. Right of Redemption. The Notes are redeemable, at the
Company's option, in whole or in part, at any time or from time to time, on or
after May 1, 2003 and prior to maturity, upon not less than 30 nor more than 60
days' prior notice mailed by first class mail to each Holder's last address as
it appears in the Security Register, at the following Redemption Prices
(expressed in percentages of principal amount at maturity), plus accrued and
unpaid interest, if any, to the Redemption Date (subject to the right of Holders
of record on the relevant Regular Record Date that is on or prior to the
Redemption Date to receive interest due on an Interest Payment Date), if
redeemed during the 12-month period commencing May 1, of the years set forth
below:

                Year                                        Redemption Price
                ----                                        ----------------
                2003..............................             105.438%
                2004..............................             103.625%
                2005..............................             101.813%
                2006 and thereafter...............             100.000%

        In addition, at any time prior to May 1, 2001, the Company may redeem up
to 35% of the principal amount at maturity of the Notes with the proceeds of one
or more Equity Offerings, at any time or from time to time in part, at a
Redemption Price (expressed as a percentage of Accreted Value) of 110.875%, plus
accrued and unpaid interest to the Redemption Date (subject to the rights of
Holders of record on the relevant Regular Record Date that is prior to the
Redemption Date to receive interest due on an Interest Payment Date); provided
that (i) Notes representing 65% of the principal amount of Notes initially
issued remain outstanding after each such redemption and (ii) notice of such
redemption is mailed within 60 days of the related Equity Offering.

               SECTION 3.02. Notices to Trustee. If the Company elects to redeem
Notes pursuant to Section 3.01, it shall notify the Trustee in writing of the
Redemption Date and the principal amount at maturity of Notes to be redeemed and
the clause of this Indenture pursuant to which redemption shall occur.

        The Company shall give each notice provided for in this Section 3.02 in
an Officers' Certificate at least ten days before mailing the notice to the
Holders pursuant to Section 3.04 (unless a shorter period shall be satisfactory
to the Trustee).

        SECTION 3.03. Selection of Notes to Be Redeemed. If less than all of the
Notes are to be redeemed at any time, the Trustee shall select the Notes to be
redeemed in compliance with the requirements, as certified to it by the Company,
of the principal national securities exchange, if
                                                             29

any, on which the Notes are listed or, if the Notes are not listed on a national
securities exchange or automated quotation system, by lot or by such other
method as the Trustee in its sole discretion shall deem fair and appropriate;
provided that no Note of $1,000 in principal amount at maturity or less shall be
redeemed in part.

        The Trustee shall make the selection from the Notes outstanding and not
previously called for redemption. Notes in denominations of $1,000 in principal
amount at maturity may only be redeemed in whole. The Trustee may select for
redemption portions (equal to $1,000 in principal amount at maturity or any
integral multiple thereof) of Notes that have denominations larger than $1,000
in principal amount at maturity. Provisions of this Indenture that apply to
Notes called for redemption also apply to portions of Notes called for
redemption. The Trustee shall notify the Company and the Registrar promptly in
writing of the Notes or portions of Notes to be called for redemption.

        SECTION 3.04. Notice of Redemption. With respect to any redemption of
Notes pursuant to Section 3.01, at least 30 days but not more than 60 days
before a Redemption Date, the Company shall mail a notice of redemption by
first-class mail to each Holder whose Notes are to be redeemed.

        The notice shall identify the Notes to be redeemed and shall state:

               (i) the Redemption Date;

               (ii) the Redemption Price;

               (iii) the name and address of the Paying Agent;

               (iv) that Notes called for redemption must be surrendered to the
        Paying Agent in order to collect the Redemption Price;

               (v) that, unless the Company defaults in making the redemption
        payment, interest on Notes called for redemption ceases to accrue on and
        after the Redemption Date and the only remaining right of the Holders is
        to receive payment of the Redemption Price plus accrued interest to the
        Redemption Date upon surrender of the Notes to the Paying Agent;

               (vi) that, if any Note is being redeemed in part, the portion of
        the principal amount at maturity (equal to $1,000 in principal amount at
        maturity or any integral multiple thereof) of such Note to be redeemed
        and that, on and after the Redemption Date, upon surrender of such Note,
        a new Note or Notes in principal amount at maturity equal to the
        unredeemed portion thereof will be reissued; and

                                                             30



<PAGE>





               (vii) that, if any Note contains a CUSIP number as provided in
        Section 2.10, no representation is being made as to the correctness of
        the CUSIP number either as printed on the Notes or as contained in the
        notice of redemption and that reliance may be placed only on the other
        identification numbers printed on the Notes.

        At the Company's request (which request may be revoked by the Company at
any time prior to the time at which the Trustee shall have given such notice to
the Holders), made in writing to the Trustee at least ten days before mailing
the notice to Holders referred to in this Section 3.04 (or such shorter period
as shall be satisfactory to the Trustee), the Trustee shall give the notice of
redemption in the name and at the expense of the Company. If, however, the
Company gives such notice to the Holders, the Company shall concurrently deliver
to the Trustee an Officers' Certificate stating that such notice has been given.

        SECTION 3.05. Effect of Notice of Redemption. Once notice of redemption
is mailed, Notes called for redemption become due and payable on the Redemption
Date and at the Redemption Price. Upon surrender of any Notes to the Paying
Agent, such Notes shall be paid at the Redemption Price, plus accrued interest,
if any, to the Redemption Date.

        Notice of redemption shall be deemed to be given when mailed, whether or
not the Holder receives the notice. In any event, failure to give such notice,
or any defect therein, shall not affect the validity of the proceedings for the
redemption of Notes held by Holders to whom such notice was properly given.

        SECTION 3.06. Deposit of Redemption Price. Prior to any Redemption Date,
the Company shall deposit with the Paying Agent (or, if the Company is acting as
its own Paying Agent, shall segregate and hold in trust as provided in Section
2.04) money sufficient to pay the Redemption Price of and accrued interest on
all Notes to be redeemed on that date other than Notes or portions thereof
called for redemption on that date that have been delivered by the Company to
the Trustee for cancellation.

        SECTION 3.07. Payment of Notes Called for Redemption. If notice of
redemption has been given in the manner provided above, the Notes or portion of
Notes specified in such notice to be redeemed shall become due and payable on
the Redemption Date at the Redemption Price stated therein, together with
accrued interest to such Redemption Date, and on and after such date (unless the
Company shall default in the payment of such Notes at the Redemption Price and
accrued interest to the Redemption Date, in which case the principal, until
paid, shall bear interest from the Redemption Date at the rate prescribed in the
Notes), such Notes shall cease to accrue interest. Upon surrender of any Note
for redemption in accordance with a notice of redemption, such Note shall be
paid and redeemed by the Company at the Redemption Price, together with accrued
interest, if any, to the Redemption Date; provided that installments of interest
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders registered as such at the close of business on the relevant Regular
Record Date.

                                                             31



<PAGE>





        SECTION 3.08. Notes Redeemed in Part. Upon surrender of any Note that is
redeemed in part, the Company shall execute and the Trustee shall authenticate
and deliver to the Holder without service charge, a new Note equal in principal
amount at maturity to the unredeemed portion of such surrendered Note.

                                 ARTICLE FOUR

                                   COVENANTS

        SECTION 4.01. Payment of Notes. The Company shall pay the principal of,
premium, if any, and interest on the Notes on the dates and in the manner
provided in the Notes and this Indenture. An installment of principal, premium,
if any, or interest shall be considered paid on the date due if the Trustee or
Paying Agent (other than the Company, a Subsidiary of the Company, or any
Affiliate of any of them) holds on that date money designated for and sufficient
to pay the installment. If the Company or any Subsidiary of the Company or any
Affiliate of any of them acts as Paying Agent, an installment of principal,
premium, if any, or interest shall be considered paid on the due date if the
entity acting as Paying Agent complies with the last sentence of Section 2.04.
As provided in Section 6.09, upon any bankruptcy or reorganization procedure
relative to the Company, the Trustee shall serve as the Paying Agent, if any,
for the Notes.

        The Company shall pay interest on overdue principal and premium, if any,
and interest on overdue installments of interest, to the extent lawful, at the
rate per annum specified in the Notes.

        SECTION 4.02. Maintenance of Office or Agency. The Company will maintain
in the Borough of Manhattan, The City of New York an office or agency where
Notes may be surrendered for registration of transfer or exchange or for
presentation for payment and where notices and demands to or upon the Company in
respect of the Notes and this Indenture may be served. The Company will give
prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency. If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the address of the Trustee set forth in Section 10.02.

        The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; provided
that no such designation or rescission shall in any manner relieve the Company
of its obligation to maintain an office or agency in the Borough of Manhattan,
The City of New York for such purposes. The Company shall give prompt written
notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency.

will not permit any of its Restricted Subsidiaries to, Incur any Indebtedness
(other than the Notes and Indebtedness existing on the Closing Date); provided
that the Company may Incur Indebtedness if, after giving effect to the
Incurrence of such Indebtedness and the receipt and application of the proceeds
therefrom, the Consolidated Leverage Ratio would be positive and (i) with
respect to any Incurrence occurring from the Closing Date through January 1,
1999, greater than zero and less than 5.5:1 and (ii) with respect to any
Incurrence occurring thereafter, greater than zero and less than 5.0:1.

        Notwithstanding the foregoing, the Company and any Restricted Subsidiary

outstanding at any time in an aggregate principal amount not to exceed the

less any amount of such Indebtedness permanently repaid as provided under
Section 4.11; (ii) Indebtedness owed (A) to the Company evidenced by an
unsubordinated promissory note or (B) to any Restricted Subsidiary; provided
that any event which results in any such Restricted Subsidiary ceasing to be a
Restricted Subsidiary or any subsequent transfer of such Indebtedness (other
than to the Company or another Restricted Subsidiary) shall be deemed, in each
case, to constitute an Incurrence of such Indebtedness not permitted by this
clause (ii); (iii) Indebtedness issued in exchange for, or the net proceeds of
which are used to refinance or refund, then outstanding Indebtedness (other than
Indebtedness Incurred under clause (i), (ii), (iv), (vi), (viii), (x) or (xi) of
this paragraph) and any refinancings thereof in an amount not to exceed the
amount so refinanced or refunded (plus premiums, accrued interest, fees and
expenses); provided that Indebtedness the proceeds of which are used to
refinance or refund the Notes or Indebtedness that is pari passu with, or
subordinated in right of payment to, the Notes shall only be permitted under
this clause (iii) if (A) in case the Notes are refinanced in part or the
Indebtedness to be refinanced is pari passu with the Notes, such new
Indebtedness, by its terms or by the terms of any agreement or instrument
pursuant to which such new Indebtedness is outstanding, is expressly made pari
passu with, or subordinate in right of payment to, the remaining Notes, (B) in
case the Indebtedness to be refinanced is subordinated in right of payment to
the Notes, such new Indebtedness, by its terms or by the terms of any agreement
or instrument pursuant to which such new Indebtedness is issued or remains
outstanding, is expressly made subordinate in right of payment to the Notes at
least to the extent that the Indebtedness to be refinanced is subordinated to
the Notes and (C) such new Indebtedness, determined as of the date of Incurrence
of such new Indebtedness, does not mature prior to the Stated Maturity of the
Indebtedness to be refinanced or refunded, and the Average Life of such new
Indebtedness is at least equal to the remaining Average Life of the Indebtedness
to be

                                                             33

refinanced or refunded; and provided further that in no event may Indebtedness
of the Company be refinanced by means of any Indebtedness of any Restricted
Subsidiary pursuant to this clause (iii); (iv) Indebtedness (A) in respect of
performance, surety or appeal bonds or letters of credit supporting trade
payables, in each case provided in the ordinary course of business, (B) under
Currency Agreements and Interest Rate Agreements; provided that such agreements
(1) are designed solely to protect the Company or its Restricted Subsidiaries
against fluctuations in foreign currency exchange rates or interest rates and
(2) do not increase the Indebtedness of the obligor outstanding at any time
other than as a result of fluctuations in foreign currency exchange rates or
interest rates or by reason of fees, indemnities and compensation payable
thereunder; and (C) arising from agreements providing for indemnification,
adjustment of purchase price or similar obligations, or from Guarantees or
letters of credit, surety bonds or performance bonds securing any obligations of
the Company or any of its Restricted Subsidiaries pursuant to such agreements,
in any case Incurred in connection with the disposition of any business, assets
or Restricted Subsidiary (other than Guarantees of Indebtedness Incurred by any
Person acquiring all or any portion of such business, assets or Restricted
Subsidiary for the purpose of financing such acquisition), in a principal amount
not to exceed the gross proceeds actually received by the Company or any
Restricted Subsidiary in connection with such disposition; (v) Indebtedness of
the Company, to the extent the net proceeds thereof are promptly (A) used to
purchase Notes tendered in an Offer to Purchase made as a result of a Change in
Control or (B) deposited to defease the Notes as described in Article Eight;

times the (A) Net Cash Proceeds received by the Company after the Closing Date

market value of property (other than cash and cash equivalents) received by the

above) in an aggregate principal amount outstanding at any time not to exceed
$100 million, less any amount of such Indebtedness permanently repaid as
provided under Section 4.11.

        (b) Notwithstanding any other provision of this Section 4.03 the maximum
amount of Indebtedness that the Company or a Restricted Subsidiary may Incur
pursuant to this Section 4.03 shall not be deemed to be exceeded, with respect
to any outstanding Indebtedness due solely to the result of fluctuations in the
exchange rates of currencies.

        (c) For purposes of determining any particular amount of Indebtedness
under this Section 4.03, (1) Indebtedness Incurred under the Credit Agreement on
or prior to the Closing Date shall be treated as Incurred pursuant to clause (i)
of the second paragraph of this Section 4.03, (2) Guarantees, Liens and
obligations with respect to letters of credit supporting Indebtedness otherwise
included in the determination of such particular amount shall not be included
and (3) any Liens granted pursuant to the equal and ratable provisions referred

determining compliance with this Section 4.03, in the event that an item of
Indebtedness meets the criteria of more than one of the types of Indebtedness
described in the above clauses (other than Indebtedness referred to in clause
(1) of the preceding sentence), the Company, in its sole discretion, shall
classify, and from time to time may reclassify, such item of Indebtedness and
only be required to include the amount and type of such Indebtedness in one of
such clauses.

        SECTION 4.04. Limitation on Restricted Payments. The Company will not,
and will not permit any Restricted Subsidiary to, directly or indirectly, (i)

and be continuing, (B) the Company could not Incur at least $1.00 of
Indebtedness under the first paragraph of Section 4.03 or (C) the aggregate
amount of all Restricted Payments (the amount, if other than in cash, to be
determined in good faith by the Board of Directors, whose determination shall be
conclusive and evidenced by a Board Resolution) made after the Closing Date
shall exceed the sum of (1) 50% of the aggregate amount of the Adjusted
Consolidated Net Income (or, if the Adjusted Consolidated Net Income is a loss,
minus 100% of the amount of such loss) (determined by excluding income resulting
from transfers of assets by the Company or a Restricted Subsidiary to an
Unrestricted Subsidiary) accrued on a cumulative basis during the period (taken
as one accounting period) beginning on the first day of the fiscal quarter
immediately following the Closing Date and ending on the last day of the last
fiscal quarter preceding the Transaction Date for which reports have been filed

holder, or are required to be redeemed, prior to the Stated Maturity of the
Notes) plus (3) an amount equal to the net reduction in Investments (other than
reductions in Permitted Investments and Investments made pursuant to clause

included in the calculation of Adjusted Consolidated Net Income), or from
redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries (valued
in each case as provided in the definition of "Investment"), not to exceed, in
each case, the amount of Investments previously made by the Company or any
Restricted Subsidiary in such Person or Unrestricted Subsidiary.

Indebtedness of the Company which is subordinated in right of payment to the

any agreement under such shares of Capital Stock or options were issued;
provided that the aggregate consideration paid for such purchase, redemption,
retirement or other acquisition for value of such shares of Capital Stock or
options after the Closing Date does not exceed $2 million in any calendar year,
or $5 million in the aggregate; (ix) Investments acquired in exchange for
Capital Stock (other than Disqualified Stock) of the Company or acquired with
Net Cash Proceeds received by the Company after the Closing Date from the
issuance and sale of its Capital Stock (other than Disqualified Stock); provided

exchange of Capital Stock for Capital Stock or Indebtedness referred to in
clause (iii) or (iv) thereof and an Investment referred to in clause (vi)
thereof), and the Net Cash Proceeds from any issuance of Capital Stock referred
to in clauses (iii) and (iv), shall be included in calculating whether the
conditions of clause (C) of the first paragraph of this Section 4.04 have been
met with respect to any subsequent Restricted Payments. In the event the
proceeds of an issuance of Capital Stock of the Company are used for the
redemption, repurchase or other acquisition of the Notes, or Indebtedness that
is pari passu with the Notes, then the Net Cash Proceeds of such issuance shall
be included in clause (C) of the

                                                             37

first paragraph of this Section 4.04 covenant only to the extent such proceeds
are not used for such redemption, repurchase or other acquisition of
Indebtedness.

        Any Restricted Payments made other than in cash shall be valued at fair
market value. The amount of any Investment "outstanding" at any time shall be
deemed to be equal to the amount of such Investment on the date made, less the
return of capital to the Company and its Restricted Subsidiaries with respect to
such Investment (up to the amount of such Investment on the date made).

        SECTION 4.05. Limitation on Dividend and Other Payment Restrictions
Affecting Restricted Subsidiaries. The Company will not, and will not permit any
Restricted Subsidiary to, create or otherwise cause or suffer to exist or become
effective any consensual encumbrance or restriction of any kind on the ability
of any Restricted Subsidiary to (i) pay dividends or make any other
distributions permitted by applicable law on any Capital Stock of such
Restricted Subsidiary owned by the Company or any other Restricted Subsidiary,
(ii) pay any Indebtedness owed to the Company or any other Restricted
Subsidiary, (iii) make loans or advances to the Company or any other Restricted
Subsidiary or (iv) transfer any of its property or assets to the Company or any
other Restricted Subsidiary.

        The foregoing provisions shall not restrict any encumbrances or
restrictions: (i) existing on the Closing Date in the Credit Agreement, this
Indenture or any other agreements in effect on the Closing Date, and any
extensions, refinancings, renewals or replacements of such agreements; provided
that the encumbrances and restrictions in any such extensions, refinancings,
renewals or replacements are no less favorable in any material respect to the
Holders than those encumbrances or restrictions that are then in effect and that
are being extended, refinanced, renewed or replaced; (ii) existing under or by
reason of applicable law; (iii) existing with respect to any Person or the
property or assets of such Person acquired by the Company or any Restricted
Subsidiary, existing at the time of such acquisition and not incurred in
contemplation thereof, which encumbrances or restrictions are not applicable to
any Person or the property or assets of any Person other than such Person or the
property or assets of such Person so acquired; (iv) in the case of clause (iv)
of the first paragraph of this Section 4.05, (A) that restrict 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, (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; (v) with
respect to a Restricted Subsidiary and imposed pursuant to an agreement that has
been entered into for the sale or disposition of all or substantially all of the
Capital Stock of, or property and assets of, such Restricted Subsidiary or (vi)
relating solely to any Foreign Subsidiaries and supporting Indebtedness of such
Foreign Subsidiaries Incurred under clause (x) of the second paragraph of

                                                             38

Section 4.03. Nothing contained in this Section 4.05 shall prevent the Company
or any Restricted Subsidiary from (1) creating, incurring, assuming or suffering
to exist any Liens otherwise permitted in Section 4.09 or (2) restricting the
sale or other disposition of property or assets of the Company or any of its
Restricted Subsidiaries that secure Indebtedness of the Company or any of its
Restricted Subsidiaries.

        SECTION 4.06. Limitation on the Issuance and Sale of Capital Stock of
Restricted Subsidiaries. The Company will not sell, and will not permit any
Restricted Subsidiary, directly or indirectly, to issue or sell, any shares of
Capital Stock of a Restricted Subsidiary (including options, warrants or other
rights to purchase shares of such Capital Stock) except (i) to the Company or a
Wholly Owned Restricted Subsidiary; (ii) issuances of director's qualifying
shares or sales to foreign nationals of shares of Capital Stock of foreign
Restricted Subsidiaries, to the extent required by applicable law; or (iii) if,
immediately after giving effect to such issuance or sale, such Restricted
Subsidiary would no longer constitute a Restricted Subsidiary and any Investment
in such Person remaining after giving effect to such issuance or sale would have
been permitted to be made under Section 4.04 if made on the date of such
issuance or sale or (iv) issuances or sales of Common Stock of a Restricted
Subsidiary, provided that the Company or such Restricted Subsidiary applies the
Net Cash Proceeds, if any, of any such sale in accordance with clause (A) or (B)
of Section 4.11.

        SECTION 4.07. Limitation on Issuances of Guarantees by Restricted
Subsidiaries. The Company will not permit any Restricted Subsidiary, directly or
indirectly, to Guarantee any Indebtedness of the Company which is pari passu
with or subordinate in right of payment to the Notes ("Guaranteed
Indebtedness"), unless (i) such Restricted Subsidiary simultaneously executes
and delivers a supplemental indenture to this Indenture providing for a
Guarantee (a "Subsidiary Guarantee") of payment of the Notes by such Restricted
Subsidiary and (ii) such Restricted Subsidiary waives and will not in any manner
whatsoever claim or take the benefit or advantage of, any rights of
reimbursement, indemnity or subrogation or any other rights against the Company
or any other Restricted Subsidiary as a result of any payment by such Restricted
Subsidiary under its Subsidiary Guarantee; provided that this paragraph shall
not be applicable to any Guarantee of any Restricted Subsidiary (x) that existed
at the time such Person became a Restricted Subsidiary and was not Incurred in
connection with, or in contemplation of, such Person becoming a Restricted
Subsidiary or (y) Indebtedness Incurred under clause (i) or (vii) of the second
paragraph of Section 4.03. If the Guaranteed Indebtedness is (A) pari passu with
the Notes, then the Guarantee of such Guaranteed Indebtedness shall be pari
passu with, or subordinated to, the Subsidiary Guarantee or (B) subordinated to
the Notes, then the Guarantee of such Guaranteed Indebtedness shall be
subordinated to the Subsidiary Guarantee at least to the extent that the
Guaranteed Indebtedness is subordinated to the Notes.

        Notwithstanding the foregoing, any Subsidiary Guarantee by a Restricted
Subsidiary may provide by its terms that it shall be automatically and
unconditionally released and discharged upon (i) any sale, exchange or transfer,
to any Person not an Affiliate of the Company, of all of

                                                             39



<PAGE>





the Company's and each Restricted Subsidiary's Capital Stock in, or all or
substantially all the assets of, such Restricted Subsidiary (which sale,
exchange or transfer is not prohibited by this Indenture) or (ii) the release or
discharge of the Guarantee which resulted in the creation of such Subsidiary
Guarantee, except a discharge or release by or as a result of payment under such
Guarantee.

        SECTION 4.08. Limitation on Transactions with Stockholders and
Affiliates. The Company will not, and will not permit any Restricted Subsidiary
to, directly or indirectly, enter into any transaction (including, without
limitation, the purchase, sale, lease or exchange of property or assets, or the
rendering of any service) with any holder (or any Affiliate of such holder) of
5% or more of any class of Capital Stock of the Company or with any Affiliate of
the Company or any Restricted Subsidiary, except upon fair and reasonable terms
no less favorable to the Company or such Restricted Subsidiary than could be
obtained, at the time of such transaction or, if such transaction is pursuant to
a written agreement, at the time of the execution of the agreement providing
therefor, in a comparable arm's-length transaction with a Person that is not
such a holder or an Affiliate.

        The foregoing limitation does not limit, and shall not apply to (i)
transactions (A) approved by a majority of the disinterested members of the
Board of Directors or (B) for which the Company or a Restricted Subsidiary
delivers to the Trustee a written opinion of a nationally recognized investment
banking firm stating that the transaction is fair to the Company or such
Restricted Subsidiary from a financial point of view; (ii) any transaction
solely between the Company and any of its Wholly Owned Restricted Subsidiaries
or solely between Wholly Owned Restricted Subsidiaries; (iii) the payment of
reasonable and customary regular fees to directors of the Company who are not
employees of the Company; (iv) any payments or other transactions pursuant to
any tax-sharing agreement between the Company and any other Person with which
the Company files a consolidated tax return or with which the Company is part of
a consolidated group for tax purposes; (v) the existence of, or the performance
by the Company or any of its Restricted Subsidiaries of its obligations under
the terms of, any stockholders agreement (including any registration rights
agreement or purchase agreement related thereto) to which it is a party as of
the Closing Date and any similar agreements which it may enter into thereafter;
provided, however, that the existence of, or the performance by the Company or
any of its Restricted Subsidiaries of obligations under any future amendment to
any such existing agreement or under any similar agreement entered into after
the Closing Date shall only be permitted by this clause (v) to the extent that
the terms of any such amendment or new agreement are not otherwise
disadvantageous to the holders of the Notes in any material respect; (vi) the
payment of all fees and expenses and the performance of obligations related to
the Transaction; or (vii) any Restricted Payments not prohibited by Section
4.04. Notwithstanding the foregoing, any transaction or series of related
transactions covered by the first paragraph of this Section 4.08 and not covered
by clauses (ii) through (vii) of this paragraph, the aggregate amount of which
exceeds $2 million in value, must be approved or determined to be fair in the
manner provided for in clause (i)(A) or (B) above.

                                                             40



<PAGE>





        SECTION 4.09. Limitation on Liens. The Company will not, and will not
permit any Restricted Subsidiary to, create, incur, assume or suffer to exist
any Lien on any of its assets or properties of any character, or any shares of
Capital Stock or Indebtedness of any Restricted Subsidiary, without making
effective provision for all of the Notes and all other amounts due under this
Indenture to be secured equally and ratably with (or, if the obligation or
liability to be secured by such Lien is subordinated in right of payment to the
Notes, prior to) the obligation or liability secured by such Lien.

        The foregoing limitation does not apply to (i) Liens existing on the
Closing Date, including Liens securing obligations under the Credit Agreement;
(ii) Liens granted after the Closing Date on any assets or Capital Stock of the
Company or its Restricted Subsidiaries created in favor of the Holders; (iii)
Liens with respect to the assets of a Restricted Subsidiary granted by such
Restricted Subsidiary to the Company or a Wholly Owned Restricted Subsidiary to
secure Indebtedness owing to the Company or such other Restricted Subsidiary;
(iv) Liens securing Indebtedness which is Incurred to refinance secured
Indebtedness which is permitted to be Incurred under clause (i) or (iii) of the
second paragraph of Section 4.03; provided that such Liens do not extend to or
cover any property or assets of the Company or any Restricted Subsidiary other
than the property or assets securing the Indebtedness being refinanced; (v)
Liens on any property or assets of a Restricted Subsidiary securing Indebtedness
of such Restricted Subsidiary permitted under Section 4.03; or (vi) Permitted
Liens.

        SECTION 4.10. Limitation on Sale-Leaseback Transactions. The Company
will not, and will not permit any Restricted Subsidiary to, enter into any
sale-leaseback transaction involving any of its assets or properties whether now
owned or hereafter acquired, whereby the Company or a Restricted Subsidiary
sells or transfers such assets or properties and then or thereafter leases such
assets or properties or any part thereof or any other assets or properties which
the Company or such Restricted Subsidiary, as the case may be, intends to use
for substantially the same purpose or purposes as the assets or properties sold
or transferred.

        The foregoing restriction does not apply to any sale-leaseback
transaction if (i) the lease is for a period, including renewal rights, of not
in excess of three years; (ii) the lease secures or relates to industrial
revenue or pollution control bonds; (iii) the transaction is solely between the
Company and any Wholly Owned Restricted Subsidiary or solely between Wholly
Owned Restricted Subsidiaries; or (iv) the Company or such Restricted
Subsidiary, within 12 months after the sale or transfer of any assets or
properties is completed, applies an amount not less than the net proceeds
received from such sale in accordance with clause (A) or (B) of the first
paragraph of Section 4.11.

        SECTION 4.11. Limitation on Asset Sales. The Company will not, and will
not permit any Restricted Subsidiary to, consummate any Asset Sale, unless (i)
the consideration received by the Company or such Restricted Subsidiary is at
least equal to the fair market value of the assets sold or disposed of and (ii)
at least 75% of the consideration received consists of cash or Temporary Cash
Investments; provided that the amount of (a) any liabilities (as shown on the
Company's or such Restricted Subsidiary's most recent balance sheet or in the
notes thereto) of

                                                             41



<PAGE>





the Company or any Restricted Subsidiary (other than liabilities that are by
their terms subordinated to the Notes), that are assumed by the transferee of
any such assets, to the extent the creditors with respect thereto execute a
written release of such liability, in favor of the Company or the Restricted
Subsidiary, as applicable, and (b) any notes or other obligations received by
the Company or such Restricted Subsidiary from such transferee that are
converted by the Company or such Restricted Subsidiary into cash (to the extent
of the cash received) within 180 days following the closing of such Asset Sale,
shall be deemed to be cash for purposes of this provision. In the event and to
the extent that the Net Cash Proceeds received by the Company or any of its
Restricted Subsidiaries from one or more Asset Sales occurring on or after the
Closing Date in any period of 12 consecutive months exceed 10% of Adjusted
Consolidated Net Tangible Assets (determined as of the date closest to the
commencement of such 12-month period for which a consolidated balance sheet of
the Company and its Subsidiaries has been filed pursuant to Section 4.18), then
the Company shall or shall cause the relevant Restricted Subsidiary to (i)
within twelve months after the date Net Cash Proceeds so received exceed 10% of
Adjusted Consolidated Net Tangible Assets (A) apply an amount equal to such
excess Net Cash Proceeds to permanently repay unsubordinated Indebtedness of the
Company, or any Restricted Subsidiary providing a Subsidiary Guarantee pursuant
to Section 4.07 or Indebtedness of any other Restricted Subsidiary, in each case
owing to a Person other than the Company or any of its Restricted Subsidiaries
or (B) invest an equal amount, or the amount not so applied pursuant to clause
(A) (or enter into a definitive agreement committing to so invest within 12
months after the date of such agreement), in property or assets (other than
current assets) of a nature or type or that are used in a business (or in a
company having property and assets of a nature or type, or engaged in a
business) similar or related to the nature or type of the property and assets
of, or the business of, the Company and its Restricted Subsidiaries existing on
the date of such investment and (ii) apply (no later than the end of the
12-month period referred to in clause (i)) such excess Net Cash Proceeds (to the
extent not applied pursuant to clause (i)) as provided in the following
paragraph of this Section 4.11. The amount of such excess Net Cash Proceeds
required to be applied (or to be committed to be applied) during such 12-month
period as set forth in clause (i) of the preceding sentence and not applied as
so required by the end of such period shall constitute "Excess Proceeds".

        If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this
Section 4.11 totals at least $10 million, the Company must commence, not later
than the fifteenth Business Day of such month, and consummate an Offer to
Purchase from the Holders on a pro rata basis an aggregate Accreted Value of
Notes equal to the Excess Proceeds on such date, at a purchase price equal to
100% of the Accreted Value of the Notes, plus, in each case, accrued interest
(if any) to the Payment Date.

        SECTION 4.12. Repurchase of Notes upon a Change of Control. The Company
shall commence, within 30 days of the occurrence of a Change of Control, and
consummate an Offer to Purchase for all Notes then outstanding, at a purchase
price equal to 101% of the Accreted Value thereof on the relevant Payment Date,
plus accrued interest, if any, to the Payment Date.

                                                             42

        SECTION 4.13. Existence. Subject to Article Five of this Indenture, the
Company will do or cause to be done all things necessary to preserve and keep in
full force and effect its existence and the existence of each of its Restricted
Subsidiaries in accordance with the respective organizational documents of the
Company and each Restricted Subsidiary and the rights (whether pursuant to
charter, partnership certificate, agreement, statute or otherwise), licenses and
franchises of the Company and each Restricted Subsidiary; provided that the
Company shall not be required to preserve any such right, license or franchise,
or the existence of any Restricted Subsidiary, if the maintenance or
preservation thereof is no longer desirable in the conduct of the business of
the Company and its Restricted Subsidiaries taken as a whole.

        SECTION 4.14. Payment of Taxes and Other Claims. The Company will pay or
discharge and shall cause each of its Subsidiaries to pay or discharge, or cause
to be paid or discharged, before the same shall become delinquent (i) all
material taxes, assessments and governmental charges levied or imposed upon (a)
the Company or any such Subsidiary, (b) the income or profits of any such
Subsidiary which is a corporation or (c) the property of the Company or any such
Subsidiary and (ii) all material lawful claims for labor, materials and supplies
that, if unpaid, might by law become a lien upon the property of the Company or
any such Subsidiary; provided that the Company shall not be required to pay or
discharge, or cause to be paid or discharged, any such tax, assessment, charge
or claim the amount, applicability or validity of which is being contested in
good faith by appropriate proceedings and for which adequate reserves have been
established.

        SECTION 4.15. Maintenance of Properties and Insurance. The Company will
cause all properties used or useful in the conduct of its business or the
business of any of its Restricted Subsidiaries to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of the Company may
be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided that nothing in
this Section 4.15 shall prevent the Company or any Restricted Subsidiary from
discontinuing the use, operation or maintenance of any of such properties or
disposing of any of them, if such discontinuance or disposal is, in the judgment
of the Company, desirable in the conduct of the business of the Company or such
Restricted Subsidiary.

        The Company will provide or cause to be provided, for itself and its
Restricted Subsidiaries, insurance (including appropriate self-insurance)
against loss or damage of the kinds customarily insured against by corporations
similarly situated and owning like properties, including, but not limited to,
products liability insurance and public liability insurance, with reputable
insurers or with the government of the United States of America, or an agency or
instrumentality thereof, in such amounts, with such deductibles and by such
methods as shall be customary for corporations similarly situated in the
industry in which the Company or any such Restricted Subsidiary, as the case may
be, is then conducting business.

                                                             43

        SECTION 4.16. Notice of Defaults. In the event that the Company or any
Officer becomes aware of any Default or Event of Default, the Company shall
promptly deliver to the Trustee an Officers' Certificate specifying such Default
or Event of Default.

        SECTION 4.17. Compliance Certificates. (a) The Company shall deliver to
the Trustee, within 45 days after the end of each fiscal quarter (90 days after
the end of the last fiscal quarter of each year), an Officers' Certificate
stating whether or not the signers know of any Default or Event of Default that
occurred during such fiscal quarter. In the case of the Officers' Certificate
delivered within 90 days after the end of the Company's fiscal year, such
certificate shall contain a certification from the principal executive officer,
principal financial officer or principal accounting officer of the Company that
a review has been conducted of the activities of the Company and its Restricted
Subsidiaries and the Company's and its Restricted Subsidiaries' performance
under this Indenture and that the Company has complied with all conditions and
covenants under this Indenture. For purposes of this Section 4.17, such
compliance shall be determined without regard to any period of grace or
requirement of notice provided under this Indenture. If any of the officers of
the Company signing such certificate has knowledge of such a Default or Event of
Default, the certificate shall describe any such Default or Event of Default and
its status. The first certificate to be delivered pursuant to this Section
4.17(a) shall be for the first fiscal quarter beginning after the execution of
this Indenture.

        (b) The Company shall deliver to the Trustee, within 90 days after the
end of each fiscal year, beginning with the fiscal year in which this Indenture
was executed, a certificate signed by the Company's independent certified public
accountants stating (i) that their audit examination has included a review of
the terms of this Indenture and the Notes as they relate to accounting matters,
(ii) that they have read the most recent Officers' Certificate delivered to the
Trustee pursuant to paragraph (a) of this Section 4.17 and (iii) whether, in
connection with their audit examination, anything came to their attention that
caused them to believe that the Company was not in compliance with any of the
terms, covenants, provisions or conditions of Article Four and Section 5.01 of
this Indenture as they pertain to accounting matters and, if any Default or
Event of Default has come to their attention, specifying the nature and period
of existence thereof; provided that such independent certified public
accountants shall not be liable in respect of such statement by reason of any
failure to obtain knowledge of any such Default or Event of Default that would
not be disclosed in the course of an audit examination conducted in accordance
with generally accepted auditing standards in effect at the date of such
examination.

        SECTION 4.18. Commission Reports and Reports to Holders. Whether or not
the Company is then required to file reports with the Commission, the Company
shall file with the Commission (unless the Commission will not accept such
filing) all such reports and other information as it would be required to file
with the Commission by Section 13(a) or 15(d) under the Exchange Act if it were
subject thereto. The Company shall supply the Trustee and each Holder or shall
supply to the Trustee for forwarding to each such Holder, without cost to such
Holder, copies of such reports and other information within 15 days after the
date it would have

                                                             44

been required to file such reports or other information with the Commission had
it been subject to such Sections; provided, however, that the copies of such
reports and information supplied to Holders may omit exhibits. The Company also
shall comply with the other provisions of TIA Section 314(a).

        SECTION 4.19. 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, or plead, or in any manner whatsoever claim or 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, premium, if any, or interest on the Notes as contemplated herein,
wherever enacted, now or at any time hereafter in force, or that may affect the
covenants or the performance of this Indenture; and (to the extent that it may
lawfully do so) the Company hereby expressly 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.

may then be relevant under the Internal Revenue Code of 1986, as amended from
time to time and requested by the Trustee.

otherwise dispose of all or substantially all of its property and assets (as an
entirety or substantially an entirety in one transaction or a series of related

Company unless: (i) the Company shall be the continuing Person, or the Person

Company is merged or that acquired or leased such property and assets of the
Company shall be a corporation organized and validly existing under the laws of
the United States of America, the United Kingdom or, in each case, any
jurisdiction thereof and shall expressly assume, by a supplemental indenture,

continuing; (iii) immediately after giving effect to such transaction on a pro
forma basis, the Company or any Person becoming the successor obligor of the

lower than the Consolidated Leverage Ratio of the Company immediately prior to
such transaction; and (iv) the Company delivers to the Trustee an Officers'
Certificate (attaching the arithmetic computations to demonstrate compliance
with clause (iii)) and Opinion of Counsel, in each case stating that such
consolidation, merger or transfer and such supplemental indenture complies with
this provision and that all conditions precedent provided for herein relating to
such transaction have been complied with; provided, however, that clause (iii)
above does not apply if, in the good faith determination of the Board of
Directors of the Company, whose determination shall be evidenced by a Board
Resolution, the principal purpose of such transaction is to change the state of
incorporation of the Company; and provided further that any such transaction
shall not have as one of its purposes the evasion of the foregoing limitations.

        SECTION 5.02. Successor Substituted. Upon any consolidation or merger,
or any sale, conveyance, transfer, lease or other disposition of all or
substantially all of the property and assets of the Company in accordance with

               (a) default in the payment of principal of (or premium, if any,
        on) any Note when the same becomes due and payable at maturity, upon
        acceleration, redemption or otherwise;

               (b) default in the payment of interest on any Note when the same

<PAGE>





               (a), (b) or (c) above) and such default or breach continues for a
period of 30 consecutive days after written notice by the Trustee or the Holders
of 25% or more in aggregate principal amount of the Notes;

               (e) there occurs with respect to any issue or issues of
Indebtedness of the Company or any Significant Subsidiary having an outstanding
principal amount of $5 million or more in the aggregate for all such issues of
all such Persons, whether such Indebtedness now exists or shall hereafter be
created,(I) an event of default that has caused the holder thereof to declare
such Indebtedness to be due and payable prior to its Stated Maturity and such
Indebtedness has not been discharged in full or such acceleration has not been
rescinded or annulled within 30 days of such acceleration and/or (II) the
failure to make a principal payment at the final (but not any interim) fixed
maturity and such defaulted payment shall not have been made, waived or extended
within 30 days of such payment default;

               (f) any final judgment or order (not covered by insurance) for
the payment of money in excess of $5 million in the aggregate for all such final
judgments or orders against all such Persons (treating any deductibles,
self-insurance or retention as not so covered) shall be rendered against the
Company or any Significant Subsidiary and shall not be paid or discharged, and
there shall be any period of 30 consecutive days following entry of the final
judgment or order that causes the aggregate amount for all such final judgments
or orders outstanding and not paid or discharged against all such Persons to
exceed $5 million during which a stay of enforcement of such final judgment or
order, by reason of a pending appeal or otherwise, shall not be in effect;

               (g) a court having jurisdiction in the premises enters a decree
or order for

               (A) relief in respect of the Company or any Significant
Subsidiary in an involuntary case under any applicable bankruptcy, insolvency or
other similar law now or hereafter in effect,

               (B) appointment of a receiver, liquidator, assignee, custodian,

<PAGE>





               (B) consents to the appointment of or taking possession by a
receiver, liquidator, assignee, custodian, trustee, sequestrator or similar
official of the Company or any Significant Subsidiary or for all or
substantially all of the property and assets of the Company or any Significant
Subsidiary or

               (C) effects any general assignment for the benefit of creditors.

        SECTION 6.02. Acceleration. If an Event of Default (other than an Event
of Default specified in clause (g) or (h) of Section 6.01 that occurs with
respect to the Company) occurs and is continuing under this Indenture, the
Trustee or the Holders of at least 25% in aggregate principal amount of the
Notes then outstanding, by written notice to the Company (and to the Trustee if
such notice is given by the Holders), may, and the Trustee at the request of
such Holders shall, declare the Accreted Value of, premium, if any, and accrued
interest on the Notes to be immediately due and payable. Upon a declaration of
acceleration, such Accreted Value, premium, if any, and accrued interest shall
be immediately due and payable. In the event of a declaration of acceleration
because an Event of Default set forth in clause (e) of Section 6.01 has occurred
and is continuing, such declaration of acceleration shall be automatically
rescinded and annulled if the event of default triggering such Event of Default
pursuant to clause (e) shall be remedied or cured by the Company or the relevant
Significant Subsidiary or waived by the holders of the relevant Indebtedness
within 60 days after the declaration of acceleration with respect thereto. If an
Event of Default specified in clause (g) or (h) of Section 6.01 occurs with
respect to the Company, the Accreted Value of, premium, if any, and accrued
interest on the Notes then outstanding shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder.

        At any time after such declaration of acceleration, but before a
judgment or decree for the payment of the money due has been obtained by the
Trustee, the Holders of at least a majority in principal amount of the
outstanding Notes by written notice to the Company and to the Trustee, may waive
all past Defaults and rescind and annul a declaration of acceleration and its
consequences if (a) the Company has paid or deposited with the Trustee a sum
sufficient to pay (i) all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, (ii) all overdue interest on all Notes, (iii) the
Accreted Value of and premium, if any, on any Notes that have become due
otherwise than by such declaration or occurrence of acceleration and interest
thereon at the rate prescribed therefor by such Notes, and (iv) to the extent
that payment of such interest is lawful, interest upon overdue interest, if any,
at the rate prescribed therefor by such Notes, (b) all existing Events of
Default, other than the non-payment of the Accreted Value of, premium, if any,
and accrued interest on the Notes that have become due solely by such
declaration of acceleration, have been cured or waived and (c) the rescission
would not conflict with any judgment or decree of a court of competent
jurisdiction.

                                                             48



<PAGE>





        SECTION 6.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may, and at the direction of the Holders of at least a
majority in principal amount of the outstanding Notes shall, pursue any
available remedy by proceeding at law or in equity to collect the payment of
principal of, premium, if any, or interest on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

        The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding.

        SECTION 6.04. Waiver of Past Defaults. Subject to Sections 6.02, 6.07
and 9.02, the Holders of at least a majority in principal amount of the
outstanding Notes, by notice to the Trustee, may waive an existing Default or
Event of Default and its consequences, except a Default in the payment of
principal of, premium, if any, or interest on any Note as specified in clause
(a) or (b) of Section 6.01 or in respect of a covenant or provision of this
Indenture which cannot be modified or amended without the consent of the Holder
of each outstanding Note affected. Upon any such waiver, such Default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to
have been cured, for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other Default or Event of Default or impair any
right consequent thereto.

        SECTION 6.05. Control by Majority. The Holders of at least a majority in
aggregate principal amount of the outstanding Notes may direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on the Trustee; provided that the
Trustee may refuse to follow any direction that conflicts with law or this
Indenture, that may involve the Trustee in personal liability, or that the
Trustee determines in good faith may be unduly prejudicial to the rights of
Holders of Notes not joining in the giving of such direction; and provided
further that the Trustee may take any other action it deems proper that is not
inconsistent with any such direction received from Holders of Notes.

        SECTION 6.06. Limitation on Suits. A Holder may not institute any
proceeding, judicial or otherwise, with respect to this Indenture or the Notes,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless:

               (i) the Holder has previously given the Trustee written notice of
        a continuing Event of Default;

               (ii) the Holders of at least 25% in aggregate principal amount of
        outstanding Notes shall have made a written request to the Trustee to
        pursue such remedy;

               (iii) such Holder or Holders offer the Trustee indemnity
        reasonably satisfactory to the Trustee against any costs, liability or
        expense;

                                                             49



<PAGE>





               (iv) the Trustee does not comply with the request within 60 days
        after receipt of the request and the offer of indemnity; and

               (v) during such 60-day period, the Holders of a majority in
        aggregate principal amount of the outstanding Notes do not give the
        Trustee a direction that is inconsistent with the request.

        For purposes of Section 6.05 of this Indenture and this Section 6.06,
the Trustee shall comply with TIA Section 316(a) in making any determination of
whether the Holders of the required aggregate principal amount of outstanding
Notes have concurred in any request or direction of the Trustee to pursue any
remedy available to the Trustee or the Holders with respect to this Indenture or
the Notes or otherwise under the law.

        A Holder may not use this Indenture to prejudice the rights of another
Holder or to obtain a preference or priority over such other Holder.

        SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding any
other provision of this Indenture, the right of any Holder of a Note to receive
payment of the Accreted Value of, premium, if any, or interest on, such Note or
to bring suit for the enforcement of any such payment, on or after the due date
expressed in the Notes, shall not be impaired or affected without the consent of
such Holder.

        SECTION 6.08. Collection Suit by Trustee. If an Event of Default in
payment of principal, premium or interest specified in clause (a), (b) or (c) of
Section 6.01 occurs and is continuing, the Trustee may recover judgment in its
own name and as trustee of an express trust against the Company or any other
obligor of the Notes for the whole amount of principal, premium, if any, and
accrued interest remaining unpaid, together with interest on overdue principal,
premium, if any, and, to the extent that payment of such interest is lawful,
interest on overdue installments of interest, in each case at the rate specified
in the Notes, and such further amount as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

        SECTION 6.09. 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 (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07) and the Holders allowed in any judicial proceedings relative to
the Company (or any other obligor of the Notes), its creditors or its property
and shall be entitled and empowered to collect and receive any monies,
securities or other property payable or deliverable upon conversion or exchange
of the Notes or upon any such claims and to distribute the same, and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar official in any

                                                             50



<PAGE>





such judicial proceeding is hereby authorized by each Holder to make such
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 to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 7.07. Nothing herein contained shall be deemed to empower
the Trustee to authorize or consent to, or accept or adopt on behalf of any
Holder, any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

        SECTION 6.10. Priorities. If the Trustee collects any money pursuant to
this Article Six, it shall pay out the money in the following order:

               First:  to the Trustee for all amounts due under Section 7.07;

               Second: to Holders for amounts then due and unpaid for principal
        of, premium, if any, and interest on the Notes in respect of which or
        for the benefit of which such money has been collected, ratably, without
        preference or priority of any kind, according to the amounts due and
        payable on such Notes for principal, premium, if any, and interest,
        respectively; and

               Third: to the Company or any other obligors of the Notes, as
        their interests may appear, or as a court of competent jurisdiction may
        direct.

        The Trustee, upon prior written notice to the Company, may fix a record
date and payment date for any payment to Holders pursuant to this Section 6.10.

        SECTION 6.11. 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 may require any party
litigant in such suit to file an undertaking to pay the costs of the suit, and
the court 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 6.11
does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section
6.07, or a suit by Holders of more than 10% in principal amount of the
outstanding Notes.

        SECTION 6.12. Restoration of Rights and Remedies. If the Trustee or any
Holder has instituted any proceeding to enforce any right or remedy under this
Indenture and such proceeding has been discontinued or abandoned for any reason,
or has been determined adversely to the Trustee or to such Holder, then, and in
every such case, subject to any determination in such proceeding, the Company,
the Trustee and the Holders shall be restored severally and respectively

                                                             51



<PAGE>





to their former positions hereunder and thereafter all rights and remedies of
the Company, Trustee and the Holders shall continue as though no such proceeding
had been instituted.

        SECTION 6.13. Rights and Remedies Cumulative. Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed,
lost or wrongfully taken Notes in Section 2.06, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

        SECTION 6.14. Delay or Omission Not Waiver. No delay or omission of the
Trustee or of any Holder to exercise any right or remedy accruing upon any Event
of Default shall impair any such right or remedy or constitute a waiver of any
such Event of Default or an acquiescence therein. Every right and remedy given
by this Article Six or by law to the Trustee or to the Holders may be exercised
from time to time, and as often as may be deemed expedient, by the Trustee or by
the Holders, as the case may be.

        SECTION 7.01. General. The duties and responsibilities of the Trustee
shall be as provided by the TIA and as set forth herein. Notwithstanding the
foregoing, no provision of this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur any financial liability in the performance
of any of its duties hereunder, or in the exercise of any of its rights or
powers, if it shall have reasonable grounds for believing that repayment of such
funds or adequate indemnity against such risk or liability is not reasonably
assured to it. Whether or not herein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Article Seven.

        SECTION 7.02. Certain Rights of Trustee. Subject to TIA Sections 315(a)
through (d):

               (i) the Trustee may rely, and shall be protected in acting or
        refraining from acting, upon any resolution, certificate, statement,
        instrument, opinion, report, notice, request, direction, consent, order,
        bond, debenture, note, other evidence of indebtedness or other paper or
        document believed by it to be genuine and to have been signed or
        presented by the proper person. The Trustee need not investigate any
        fact or matter stated in the document and may in good faith conclusively
        rely as to the truth of the statements and the correctness of the
        opinions therein;

                                                             52



<PAGE>





               (ii) before the Trustee acts or refrains from acting, it may
        require an Officers' Certificate or an Opinion of Counsel, which shall
        conform to Section 10.04. The Trustee shall not be liable for any action
        it takes or omits to take in good faith in reliance on such certificate,
        opinion and/or an accountants' certificate;

               (iii) the Trustee may act through its attorneys and agents and
        shall not be responsible for the misconduct or negligence of any
        attorney or agent appointed with due care by it hereunder;

               (iv) the Trustee shall be under no obligation to exercise any of
        the rights or powers vested in it by this Indenture at the request or
        direction of any of the Holders, unless such Holders shall have offered
        to the Trustee security or indemnity reasonably satisfactory to it
        against the costs, expenses and liabilities that might be incurred by it
        in compliance with such request or direction;

               (v) the Trustee shall not be liable for any action it takes or
        omits to take in good faith that it believes to be authorized or within
        its rights or powers or for any action it takes or omits to take in
        accordance with the direction of the Holders of a majority in principal
        amount of the outstanding Securities 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, provided that the Trustee's conduct does not
        constitute negligence or bad faith;

               (vi) whenever in the administration of this Indenture the Trustee
        shall deem it desirable that a matter be proved or established prior to
        taking, suffering or omitting any action hereunder, the Trustee (unless
        other evidence be herein specifically prescribed) may, in the absence of
        bad faith on its part, rely upon an Officers' Certificate;

               (vii) 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, direction,
        consent, order, bond, debenture, note, other evidence of indebtedness or
        other paper or document, but the Trustee, in its discretion, may make
        such further inquiry or investigation into such facts or matters as it
        may see fit, and, if the Trustee shall determine to make such further
        inquiry or investigation, it shall be entitled to examine the books,
        records and premises of the Company personally or by agent or attorney;
        and

               (viii) any request or direction of the Company mentioned herein
        shall be sufficiently evidenced by a Company Order and any resolution of
        the Board of Directors may be sufficiently evidenced by a Board
        Resolution.

        SECTION 7.03. Individual Rights of Trustee. The Trustee, in its
individual or any other capacity, may become the owner or pledgee of Notes and
may otherwise deal with the Company

                                                             53

or its Affiliates with the same rights it would have if it were not the Trustee.
Any Agent may do the same with like rights. However, the Trustee is subject to
TIA Sections 310(b) and 311.

        SECTION 7.04. Trustee's Disclaimer. The Trustee (i) makes no
representation as to the validity or adequacy of this Indenture or the Notes,
(ii) shall not be accountable for the Company's use or application of the
proceeds from the Notes and (iii) shall not be responsible for any statement in
the Notes other than its certificate of authentication.

        SECTION 7.05. Notice of Default. If any Default or any Event of Default
occurs and is continuing and if such Default or Event of Default is known to the
Trustee, the Trustee shall mail to each Holder in the manner and to the extent
provided in TIA Section 313(c) notice of the Default or Event of Default within
45 days after it occurs, unless such Default or Event of Default has been cured;
provided, however, that, except in the case of a default in the payment of the
principal of, premium, if any, or interest on any Note, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determine that the withholding of such
notice is in the interest of the Holders.

        SECTION 7.06. Reports by Trustee to Holders. Within 60 days after each
April 15, beginning with April 15, 1999, the Trustee shall mail to each Holder
as provided in TIA Section 313(c) a brief report dated as of such April 15, if
required by TIA Section 313(a).

        A copy of each report at the time of its mailing to the Holders of

Trustee shall have a lien prior to the Notes on all money or property held or
collected by the Trustee, in its capacity as Trustee, except money or property
held in trust to pay principal of, premium, if any, and interest on particular
Notes.

        If the Trustee incurs expenses or renders services after the occurrence
of an Event of Default specified in clause (g) or (h) of Section 6.01, the
expenses and the compensation for the services will be intended to constitute
expenses of administration under Title 11 of the United States Bankruptcy Code
or any applicable federal or state law for the relief of debtors.

        The provisions of this Section 7.07 shall survive the termination of
this Indenture.

        The Trustee shall comply with the provisions of TIA Section 313(b)(2) to
the extent applicable.

        SECTION 7.08. Replacement of Trustee. A resignation or removal of the
Trustee and appointment of a successor Trustee shall become effective only upon
the successor Trustee's acceptance of appointment as provided in this Section
7.08.

        The Trustee may resign at any time by so notifying the Company in
writing at least 30 days prior to the date of the proposed resignation. The
Holders of a majority in principal amount at maturity of the outstanding Notes
may remove the Trustee by so notifying the Trustee in writing and may appoint a
successor Trustee with the consent of the Company. The Company may remove the
Trustee by Company Order given at least 30 days prior to the proposed date of
removal if: (i) the Trustee is no longer eligible under Section 7.10; (ii) the
Trustee is adjudged a bankrupt or an insolvent; (iii) a receiver or other public
officer takes charge of the Trustee or its property; or (iv) the Trustee becomes
incapable of acting.

        If the Trustee resigns or is removed, or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Company. If
the successor Trustee does not deliver its written acceptance required by the
next succeeding paragraph of this Section 7.08 within 30 days after the retiring
Trustee resigns or is removed, the retiring Trustee, the Company or the Holders
of a majority in principal amount at maturity of the outstanding Notes may, at
the expense of the Company, petition any court of competent jurisdiction for the
appointment of a successor Trustee.

        A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after the
delivery of such written acceptance, subject to the lien provided in Section
7.07, (i) the retiring Trustee shall transfer all property held by it as Trustee
to the successor Trustee, (ii) the resignation or removal of the retiring
Trustee shall

                                                             55

become effective and (iii) the successor Trustee shall have all the rights,
powers and duties of the Trustee under this Indenture. A successor Trustee shall
mail notice of its succession to each Holder. No successor Trustee shall accept
its appointment unless at the time of such acceptance such successor Trustee
shall be qualified and eligible under this Article.

        If the Trustee is no longer eligible under Section 7.10 or shall fail to
comply with TIA Section 310(b), any Holder who satisfies the requirements of TIA
Section 310(b) may petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor Trustee. If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section 7.08, the Trustee shall resign immediately in the manner and with the
effect provided in this Section.

        The Company shall give notice of any resignation and any removal of the
Trustee and each appointment of a successor Trustee to all Holders. Each notice
shall include the name of the successor Trustee and the address of its Corporate
Trust Office.

        Notwithstanding replacement of the Trustee pursuant to this Section
7.08, the Company's obligation under Section 7.07 shall continue indefinitely
for the benefit of the retiring Trustee.

        SECTION 7.09. Successor Trustee by Merger, Etc. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all of its corporate trust business to, another corporation or national banking
association, the resulting, surviving or transferee corporation or national
banking association without any further act shall be the successor Trustee with
the same effect as if the successor Trustee had been named as the Trustee
herein, provided such corporation shall be otherwise qualified and eligible
under this Article.

        SECTION 7.10. Eligibility. This Indenture shall always have a Trustee
who satisfies the requirements of TIA Section 310(a)(1). The Trustee shall have
a combined capital and surplus of at least $25 million as set forth in its most
recent published annual report of condition that is subject to the requirements
of applicable Federal or state supervising or examining authority. If at any
time the Trustee shall cease to be eligible in accordance with the provisions of
this Section, the Trustee shall resign immediately in the manner and with the
effect specified in this Article.

        SECTION 7.11. Money Held in Trust. The Trustee shall not be liable for
interest on any money received by it except as the Trustee may agree with the
Company. Money held in trust by the Trustee need not be segregated from other
funds except to the extent required by law and except for money held in trust
under Article Eight of this Indenture.

        of independent public accountants expressed in a written certification
        thereof delivered to the Trustee), without consideration of any
        reinvestment of any interest thereon, to pay principal, premium, if,

Trustee upon request shall acknowledge in writing the discharge of the Company's
obligations under the Notes and this Indenture except for those surviving

        Trustee (or another trustee satisfying the requirements of Section 7.10)
        and conveyed all right, title and interest to the Trustee for the
        benefit of the Holders, under the terms of an irrevocable trust

        funds in trust, specifically pledged to the Trustee for the benefit of
        the Holders as security for payment of the principal of, premium, if
        any, and interest, if any, on the Notes, and dedicated solely to, the
        benefit of the Holders, in and to (1) money in an amount, (2) U.S.
        Government Obligations that, through the payment of interest, premium,
        if any, and principal in respect thereof in accordance with their terms,
        will provide, not later than one day before the due date of any payment
        referred to in this clause (A), money in an amount or (3) a combination
        thereof in an amount sufficient, in the opinion of a nationally

        premium, if any, and interest with respect to the Notes;

               (B) the Company has delivered to the Trustee (1) either (x) an
        Opinion of Counsel to the effect that Holders will not recognize income,
        gain or loss for federal income tax purposes as a result of the

        subject to federal income tax on the same amount and in the same manner
        and at the same times as would have been the case if such option had not
        been exercised, which Opinion of Counsel shall be based upon (and
        accompanied by a copy of) a ruling of the Internal Revenue Service to
        the same effect unless there has been a change in applicable federal
        income tax law after the Closing Date such that a ruling is no longer
        required or (y) a ruling directed to the Trustee received from the
        Internal Revenue Service to the same effect as the aforementioned
        Opinion of Counsel and (2) an Opinion of Counsel to the effect that the
        creation of the defeasance trust does not violate the Investment Company
        Act of 1940 and that after the passage of 123 days following the deposit
        (except, with respect to any trust funds for the account of any Holder
        who may be deemed to be an "insider" for purposes of the United States
        Bankruptcy Code, after one year following the deposit), the trust funds
        will not be subject to the effect of Section 547 of the United States
        Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law in
        a case commenced by or against the Company under either such statute,
        and either (I) the trust funds will no longer remain the property of the
        Company (and therefore will

        not be subject to the effect of any applicable bankruptcy, insolvency,
        reorganization or similar laws affecting creditors' rights generally) or
        (II) if a court were to rule under any such law in any case or
        proceeding that the trust funds remained property of the Company, (a)
        assuming such trust funds remained in the possession of the Trustee
        prior to such court ruling to the extent not paid to the Holders, the
        Trustee will hold, for the benefit of the Holders, a valid and perfected
        security interest in such trust funds that is not avoidable in
        bankruptcy or otherwise except for the effect of Section 552(b) of the
        United States Bankruptcy Code on interest on the trust funds accruing
        after the commencement of a case under such statute, (b) the Holders
        will be entitled to receive adequate protection of their interests in
        such trust funds if such trust funds are used in such case or proceeding
        and (c) no property, rights in property or other interests granted to
        the Trustee or the Holders in exchange for, or with respect to, such
        trust funds will be subject to any prior rights of holders of other
        Indebtedness of the Company or any of its Subsidiaries;

               (C) immediately after giving effect to such deposit, on a pro
        forma basis, no Default or Event of Default shall have occurred and be
        continuing on the date of such deposit or during the period ending on
        the 123rd day after such date of such deposit, and such deposit shall
        not result in a breach or violation of, or constitute a default under,
        this Indenture or any other agreement or instrument to which the Company
        or any of its Subsidiaries is a party or by which the Company or any of
        its Subsidiaries is bound;

               (D) if the Notes are then listed on a national securities
        exchange, the Company has delivered to the Trustee an Opinion of Counsel
        to the effect that the Notes will not be delisted as a result of such
        deposit, defeasance and discharge; and

               (E) the Company has delivered to the Trustee an Officers'
        Certificate and an Opinion of Counsel, in each case stating that all
        conditions precedent provided for herein relating to the defeasance
        contemplated by this Section 8.02 have been complied with.

year) period referred to in clause (B)(2) of this Section 8.02, none of the
Company's obligations under this Indenture shall be discharged. Subsequent to
the end of such 123-day (or one year) period with respect to this Section 8.02,
the Company's obligations in Sections 2.02, 2.03, 2.04, 2.05, 2.06, 2.11, 4.01,
4.02, 8.04, 8.05, 8.06 and the rights, powers, trusts, duties and immunities of
the Trustee hereunder shall survive until the Notes are no longer outstanding.
Thereafter, only the Company's obligations in Sections 7.07, 8.04, 8.05 and 8.06
shall survive. If and when a ruling from the Internal Revenue Service or an
Opinion of Counsel referred to in clause (B)(1) of this Section 8.02 is able to
be provided specifically without regard to, and not in reliance upon, the
continuance of the Company's obligations under Section 4.01, then the Company's
obligations under such Section 4.01 shall cease upon delivery to the Trustee of
such ruling or Opinion of Counsel and compliance with the other conditions
precedent provided for herein relating to the defeasance contemplated by this
Section 8.02.

        Company under either such statute, and either (1) the trust funds will
        no longer remain the property of the Company (and therefore will not be
        subject to the effect of any applicable bankruptcy, insolvency,
        reorganization or similar laws

        SECTION 8.06. Reinstatement. If the Trustee or Paying Agent is unable to
apply any money or U.S. Government Obligations in accordance with Section 8.01,
8.02 or 8.03, as the case may be, 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 Company's obligations
under this Indenture and the Notes shall be revived and reinstated as though no
deposit had occurred pursuant to Section 8.01, 8.02 or 8.03, as the case may be,
until such time as the Trustee or Paying Agent is permitted to apply all such
money or U.S. Government Obligations in accordance with Section 8.01, 8.02 or
8.03, as the case may be; provided that, if the Company has made any payment of
principal of, premium, if any, or interest on any Notes because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money or U.S.
Government Obligations held by the Trustee or Paying Agent.

                      AMENDMENTS, SUPPLEMENTS AND WAIVERS

        SECTION 9.01. Without Consent of Holders. The Company, when authorized
by a resolution of its Board of Directors (as evidenced by a Board Resolution
delivered to the Trustee), and the Trustee may amend or supplement this
Indenture or the Notes without notice to or the consent of any Holder:

               (1) to cure any ambiguity, defect or inconsistency in this
        Indenture; provided that such amendments or supplements shall not, in
        the good faith opinion of the Board of Directors as evidenced by a Board
        Resolution, adversely affect the interests of the Holders in any
        material respect;

               (2)     to comply with Article Five;

                                                             62

               (3) to comply with any requirements of the Commission in
        connection with the qualification of this Indenture under the TIA;

               (4) to evidence and provide for the acceptance of appointment
        hereunder by a successor Trustee;

               (5) to provide for uncertificated Notes in addition to or in
        place of certificated Notes;

               (6) to add one or more subsidiary guarantees on the terms
        required by this Indenture; or

               (7) to make any change that, in the good faith opinion of the
        Board of Directors as evidenced by a Board Resolution, does not
        materially and adversely affect the rights of any Holder.

        SECTION 9.02. With Consent of Holders. Subject to Sections 6.04 and 6.07
and without prior notice to the Holders, the Company, when authorized by its
Board of Directors (as evidenced by a Board Resolution delivered to the
Trustee), and the Trustee may amend this Indenture and the Notes with the
written consent of the Holders of a majority in aggregate principal amount at
maturity of the Notes then outstanding, and the Holders of a majority in
aggregate principal amount at maturity of the Notes then outstanding by written
notice to the Trustee may waive future compliance by the Company with any
provision of this Indenture or the Notes.

        Notwithstanding the provisions of this Section 9.02, without the consent
of each Holder affected, an amendment or waiver, including a waiver pursuant to
Section 6.04, may not:

               (i) change the Stated Maturity of the principal of, or any
        installment of interest on, any Note;

               (ii) reduce the principal amount or Accreted Value of, premium,
        if any, or interest, on any Note;

               (iii) change the place or currency of payment of principal of, or
        premium, if any, or interest on, any Note;

               (iv) impair the right to institute suit for the enforcement of
        any payment on or after the Stated Maturity (or, in the case of
        redemption, on or after the Redemption Date) on any Note;

               (v) reduce the above-stated percentage of outstanding Notes the
        consent of whose Holders is necessary to modify or amend this Indenture;

                                                             63



<PAGE>





               (vi) waive a default in the payment of principal of, premium, if
        any, or interest on, the Notes;

               (vii) reduce the percentage or aggregate principal amount of
        outstanding Notes the consent of whose Holders is necessary for waiver
        of compliance with certain provisions of this Indenture or for waiver of
        certain defaults; or

               (viii) modify any of the provisions of this Section 9.02, except
        to increase any such percentage or to provide that certain other
        provisions of this Indenture cannot be modified or waived without the
        consent of the Holder of each outstanding Note affected thereby.

        It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

        After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Company shall mail to the Holders affected thereby a notice
briefly describing the amendment, supplement or waiver. The Company will mail
supplemental indentures to Holders upon request. Any failure of the Company to
mail such notice, or any defect therein, shall not, however, in any way impair
or affect the validity of any such supplemental indenture or waiver.

        SECTION 9.03. Revocation and Effect of Consent. Until an amendment or
waiver becomes effective, a consent to it by a Holder is a continuing consent by
the Holder and every subsequent Holder of a Note or portion of a Note that
evidences the same debt as the Note of the consenting Holder, even if notation
of the consent is not made on any Note. However, any such Holder or subsequent
Holder may revoke the consent as to its Note or portion of its Note. Such
revocation shall be effective only if the Trustee receives the notice of
revocation before the date the amendment, supplement or waiver becomes
effective. An amendment, supplement or waiver shall become effective on receipt
by the Trustee of written consents from the Holders of the requisite percentage
in principal amount of the outstanding Notes.

        The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver. If a record date is fixed, then, notwithstanding the last
two sentences of 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 consent to such amendment, supplement or waiver or
to revoke any consent previously given, whether or not such persons continue to
be Holders after such record date. No such consent shall be valid or effective
for more than 90 days after such record date.

                                                             64



<PAGE>





        After an amendment, supplement or waiver becomes effective, it shall
bind every Holder unless it is of the type described in the second paragraph of
Section 9.02. In case of an amendment or waiver of the type described in the
second paragraph of Section 9.02, the amendment or waiver shall bind each Holder
who has consented to it and every subsequent Holder of a Note that evidences the
same indebtedness as the Note of the consenting Holder.

        SECTION 9.04. Notation on or Exchange of Notes. If an amendment,
supplement or waiver changes the terms of a Note, the Trustee may require the
Holder to deliver such Note to the Trustee. At the Company's expense, the
Trustee may place an appropriate notation on the Note about the changed terms
and return it to the Holder and the Trustee may place an appropriate notation on
any Note thereafter authenticated. Alternatively, if the Company or the Trustee
so determines, the Company in exchange for the Note shall issue and the Trustee
shall authenticate a new Note that reflects the changed terms. Failure to make
the appropriate notation, or issue a new Note, shall not affect the validity and
effect of such amendment, supplement or waiver.

        SECTION 9.05. Trustee to Sign Amendments, Etc. The Trustee shall be
entitled to receive, and shall be fully protected in relying upon, an Opinion of
Counsel stating that the execution of any amendment, supplement or waiver
authorized pursuant to this Article Nine is authorized or permitted by this
Indenture and that it will be valid and binding upon the Company. Subject to the
preceding sentence, the Trustee shall sign such amendment, supplement or waiver
if the same does not adversely affect the rights, duties, liabilities or
immunities of the Trustee. The Trustee may, but shall not be obligated to,
execute any such amendment, supplement or waiver that affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise.

        SECTION 9.06. Conformity with Trust Indenture Act. Every supplemental
indenture executed pursuant to this Article Nine shall conform to the
requirements of the TIA as then in effect.

                                 MISCELLANEOUS

        SECTION 10.01. Trust Indenture Act of 1939. This Indenture shall be
subject to the provisions of the TIA that are required to be a part of this
Indenture and shall, to the extent applicable, be governed by such provisions.

        SECTION 10.02. Notices. Any notice or communication shall be
sufficiently given if in writing and delivered in person, mailed by first-class
mail or sent by telecopier transmission addressed as follows:

               Telecopier No.: (212) 852-1626
               Attention: Louis Young, Corporate Trust Department

        The Company or the Trustee by notice to the other may designate
additional or different addresses for subsequent notices or communications.

        Any notice or communication mailed to a Holder shall be mailed to it at
its address as it appears on the Security Register by first-class mail and shall
be sufficiently given to him if so mailed within the time prescribed. Any notice
or communication shall also be so mailed to any Person described in TIA Section
313(c), to the extent required by the TIA. Copies of any such communication or
notice to a Holder shall also be mailed to the Trustee and each Agent at the
same time.

        Failure to mail notice or communication to a Holder as provided herein
or any defect in any such notice or communication shall not affect its
sufficiency with respect to other Holders. Except for a notice to the Trustee,
which is deemed given only when received, and except as otherwise provided in
this Indenture, if a notice or communication is mailed in the manner provided in
this Section 10.02, it is duly given, whether or not the addressee receives it.

        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 regular mail service or by reason
of any other cause it shall be impracticable to give such notice by mail, then
such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

Notes at the close of business on the April 15 or October 15 immediately
preceding the Interest Payment Date) on each Interest Payment Date, commencing
November 1, 2001; provided that no interest shall accrue on the principal amount
of this Note prior to May 1, 2001

        Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from May 1, 2001;
provided that, if there is no existing default in the payment of interest and
this Note is authenticated between a Regular Record Date referred to on the face
hereof and the next succeeding Interest Payment Date, interest shall accrue from
such Interest Payment Date. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.

        The Company shall pay interest on overdue principal and premium, if any,
and interest on overdue installments of interest, to the extent lawful, at a
rate per annum that is 2% in excess of the rate otherwise payable.

2.  Method of Payment.

        The Company will pay interest (except defaulted interest) on the
principal amount of the Notes as provided above on each May 1 and November1,
commencing November 1, 2001 to the persons who are Holders (as reflected in the
Security Register at the close of business on the April 15 or October 15
immediately preceding the Interest Payment Date), in each case, even if the Note
is canceled on registration of transfer or registration of exchange after such
record date; provided that, with respect to the payment of principal, the
Company will make payment to the Holder that surrenders this Note to a Paying
Agent on or after May 1, 2008.

                                                             A-6

        The Company will pay principal, premium, if any, and as provided above,
interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts. However, the Company may pay
principal, premium, if any, and interest by its check payable in such money. It
may mail an interest check to a Holder's registered address (as reflected in the
Security Register). If a payment date is a date other than a Business Day at a
place of payment, payment may be made at that place on the next succeeding day
that is a Business Day and no interest shall accrue for the intervening period.

3.  Paying Agent and Registrar.

        Initially, the Trustee will act as authenticating agent, Paying Agent
and Registrar. The Company may change any authenticating agent, Paying Agent or
Registrar without notice. The Company, any Subsidiary or any Affiliate of any of
them may act as Paying Agent, Registrar or co-Registrar.

4.  Indenture; Limitations.

        The Company issued the Notes under an Indenture dated as of April 30,
1998 (the "Indenture"), between the Company and United States Trust Company of
New York, as trustee (the "Trustee"). Capitalized terms herein are used as
defined in the Indenture unless otherwise indicated. The terms of the Notes
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act. The Notes are subject to all such terms,
and Holders are referred to the Indenture and the Trust Indenture Act for a
statement of all such terms. To the extent permitted by applicable law, in the
event of any inconsistency between the terms of this Note and the terms of the
Indenture, the terms of the Indenture shall control.

        The Notes are general unsecured obligations of the Company.

        The Company may, subject to Article Four of the Indenture and applicable
law, issue additional Notes under the Indenture.

5.  Optional Redemption.

        The Notes are redeemable, at the Company's option, in whole or in part,
at any time or from time to time, on or after May 1, 2003 and prior to maturity,
upon not less than 30 nor more than 60 days' prior notice mailed by first class
mail to each Holder's last address, as it appears in the Security Register, at
the following Redemption Prices (expressed in percentages of principal amount at
maturity), plus accrued and unpaid interest to the Redemption Date (subject to
the right of Holders of record on the relevant Regular Record Date that is prior
to the Redemption Date to receive interest due on an Interest Payment Date), if
redeemed during the 12-month period commencing May 1 of the years set forth
below:

                                                             A-7



<PAGE>





                Year                   Redemption Price
                ----                   ----------------
                2003.............          105.438%
                2004.............          103.625%
                2005.............          101.813%
                2006 and thereafter        100.000%

        In addition, at any time and from time to time prior to May 1, 2001, the
Company may redeem up to 35% of the principal amount at maturity of the Notes
with the proceeds of one or more Equity Offerings, at any time or from time to
time in part, at a Redemption Price (expressed as a percentage of Accreted Value
on the Redemption Date) of 110.875%, plus accrued and unpaid interest to the
Redemption Date (subject to the rights of Holders of record on the relevant
Regular Record Date that is prior to the Redemption Date to receive interest due
on an Interest Payment Date); provided that (i) Notes representing 65% of the
principal amount of notes initially issued remain outstanding after each such
redemption and (ii) notice of such redemption is mailed within 60 days of the
related Equity Offering.

        Notes in original denominations larger than $1,000 may be redeemed in
part. On and after the Redemption Date, interest ceases to accrue on Notes or
portions of Notes called for redemption, unless the Company defaults in the
payment of the Redemption Price.

6. Repurchase upon Change of Control.

        Upon the occurrence of any Change of Control, each Holder shall have the
right to require the repurchase of its Notes by the Company in cash pursuant to
the offer described in the Indenture at a purchase price equal to 101% of the
Accreted Value thereof plus accrued and unpaid interest, if any, to the date of
purchase (the "Payment Date").

        A notice of such Change of Control will be mailed within 30 days after
any Change of Control occurs to each Holder at its last address as it appears in
the Security Register. Notes in original denominations larger than $1,000 may be
sold to the Company in part. On and after the Payment Date, interest ceases to
accrue and original issue discount ceases to accrete on Notes or portions of
Notes surrendered for purchase by the Company, unless the Company defaults in
the payment of the purchase price.

7.  Denominations; Transfer; Exchange.

        The Notes are in registered form without coupons in denominations of
$1,000 of principal amount at maturity and multiples of $1,000 in excess
thereof. A Holder may register the transfer or exchange of Notes in accordance
with the Indenture. The Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay any taxes and
fees required by law or permitted by the Indenture. The Registrar need not
register the transfer or exchange of any Notes selected for redemption. Also, it
need not register the transfer

                                                             A-8



<PAGE>





or exchange of any Notes for a period of 15 days before the day of mailing of a
notice of redemption of Notes selected for redemption.

8.  Persons Deemed Owners.

        A Holder shall be treated as the owner of a Note for all purposes.

9.  Unclaimed Money.

        If money for the payment of principal, premium, if any, or interest
remains unclaimed for two years, the Trustee and the Paying Agent will pay the
money back to the Company at its request. After that, Holders entitled to the
money must look to the Company for payment, unless an abandoned property law
designates another Person, and all liability of the Trustee and such Paying
Agent with respect to such money shall cease.

10. Discharge Prior to Redemption or Maturity.

        If the Company deposits with the Trustee money or U.S. Government
Obligations sufficient to pay the then outstanding principal of, premium, if
any, and accrued interest on the Notes (a) to redemption or maturity, the
Company will be discharged from the Indenture and the Notes, except in certain
circumstances for certain provisions thereof, and (b) to the Stated Maturity,
the Company will be discharged from certain covenants set forth in the
Indenture.

11.  Amendment; Supplement; Waiver.

        Subject to certain exceptions, the Indenture or the Notes may be amended
or supplemented with the consent of the Holders of at least a majority in
principal amount of the Notes then outstanding, and any existing default or
compliance with any provision may be waived with the consent of the Holders of
at least a majority in principal amount of the Notes then outstanding. Without
notice to or the consent of any Holder, the parties thereto may amend or
supplement the Indenture or the Notes to, among other things, cure any
ambiguity, defect or inconsistency and make any change that does not materially
and adversely affect the rights of any Holder.

continuing, the Trustee may, and at the direction of the Holders of at least 25%
in aggregate principal amount of the Notes then outstanding shall, declare all
the Notes to be due and payable. If a bankruptcy or insolvency default with
respect to the Company occurs and is continuing, the Notes automatically become

obligations of the Company under the Notes or the Indenture or for any claim
based on, in respect of or by reason of, such obligations or their creation.
Each Holder by accepting a Note waives and releases all such liability. The
waiver and release are part of the consideration for the issuance of the Notes.

17.  Authentication.

        This Note shall not be valid until the Trustee or authenticating agent
signs the certificate of authentication on the other side of this Note.

18.  Abbreviations.

                                                             A-11

members, of whom (i) three shall be nominated by the CSH Shareholders, (ii) two
shall be nominated by the CSH Shareholders and shall be individuals which are
not "Affiliates" or "Associates" (as those terms are used within the meaning of

Shareholder or its Affiliates, (iii) two shall be nominated by the CSH
Shareholders and shall be individuals who are executive officers of the Company
or its Subsidiaries and (iv) two shall be nominated by the Kleinknecht
Shareholders. Each Shareholder entitled to vote for the election of directors to
the Board agrees that it will vote its shares of Common Stock or execute
consents, as the case may be, and take all other necessary action (including
causing the Company to call a special meeting of shareholders) in order to
ensure that the composition of the Board is as set forth in this Section 2.01;
provided that, no Shareholder shall be required to vote for the CSH
Shareholders' or the Kleinknecht Shareholders' nominee(s) , as applicable, if
the number of Shares held by the group of Shareholders, as applicable, making
the nomination is, at the close of business on the day preceding such vote or
execution of consents, (x) less than 5% of the outstanding number of Shares of
Common Stock, in the case of the CSH Shareholders or (y) less than 50% of its

  Section 2.02. Removal. Subject to applicable law, each Shareholder agrees that
if, at any time, it is then entitled to vote for the removal of directors of the
Company, it will not vote any of its Shares in favor of the removal of any
director who shall have been designated or nominated pursuant to Section 2.01
unless such removal shall be for Cause or the Person(s) entitled to designate or
nominate such director shall have consented to such removal in writing, provided
that if the Persons entitled to designate or nominate any director pursuant to
Section 2.01 shall request the removal, with or without Cause, of such director
in writing, each such Shareholder shall vote its shares of Common Stock in favor
of such removal. Removal for "Cause" shall mean removal of a director because of
such director's (a) willful and continued failure substantially to perform his
duties with the Company in his established position, (b) willful conduct which
is injurious to the Company or any of its Subsidiaries, monetarily or otherwise,

  individual (the "Nominee") to fill such vacancy and serve as a director of the
  Company; and

    (b) each Shareholder then entitled to vote for the election of the Nominee
  as a director of the Company agrees that it will vote its Shares, or execute a
  written consent, as the case may be, in order to ensure that the Nominee be
  elected to the Board; provided that, no Shareholder shall be required to vote
  for another party's Nominee(s) if the aggregate number of Shares held by the
  Shareholder or group of Shareholders, as applicable, making the nomination is,
  at the close of business of the day preceding such vote or execution of
  consents, less than (x) 5% of the outstanding number of Shares of Common
  Stock, in the case of the CSH Shareholders or (y) less than 50% of the Initial
  Ownership of Common Stock, in the case of the Kleinknecht Shareholders.

  Section 2.04. Action by the Board. (a) A quorum at any meeting of the Board
shall consist of five directors.

  (b) All actions of the Board shall require the affirmative vote of at least a
majority of the directors present at a duly convened meeting of the Board at
which a quorum is present or the unanimous written consent of the Board;
provided that, in the event there is a vacancy on the Board and an individual
has been nominated to fill such vacancy, the first order of business shall be to
fill such vacancy.

Rights pursuant to this Section 4.01 may consummate the Tag-Along Sale on

specified in the Tag-Along Notice by up to 5%) within 120 days of the date on
which Tag-Along Rights shall have been waived, exercised or expire.

Section 4.02 Sale to a representative of CSH designated in the Section 4.02
Notice certificates representing all Subject Securities held by such Kleinknecht
Shareholder, Walsh Shareholder, Servidio Shareholder and LSH Shareholder duly
endorsed, together with all other documents required to be executed in
connection with such Section 4.02 Sale or, if such delivery is not permitted by
applicable law, an unconditional agreement to deliver such Subject Securities
pursuant to this Section 4.02 at the closing for such Section 4.02 Sale against
delivery to such Kleinknecht Shareholder, Walsh Shareholder, Servidio
Shareholder and LSH Shareholder of the consideration therefor. If a Kleinknecht
Shareholder, Walsh Shareholder, Servidio Shareholder or LSH Shareholder should
fail to deliver such certificates to CSH, the Company shall cause the books and
records of the Company to show that such Subject Securities are bound by the
provisions of this Section 4.02 and that such Subject Securities shall be
transferred to the purchaser of the Subject Securities immediately upon
surrender for transfer by the holder thereof.

  (b) The CSH Shareholders shall have a period of 120 days from the date of
receipt of the Section 4.02 Notice to consummate the Section 4.02 Sale on the
terms and conditions set forth in such Section 4.02 Sale Notice. If the Section
4.02 Sale shall not have been consummated during such period, CSH shall return
to each of the Kleinknecht Shareholders, each of the Walsh Shareholders, each of
the Servidio Shareholders and each of the LSH Shareholders all certificates
representing Shares that such Kleinknecht Shareholder, Walsh Shareholder,
Servidio Shareholder or LSH Shareholder, as the case may be, may have delivered
for transfer pursuant hereto, together with any documents in the possession of
CSH executed by the Kleinknecht Shareholder, the Walsh Shareholder, the Servidio
Shareholder or the LSH Shareholder, as the case may be, in connection with such
proposed transfer, and all the restrictions on transfer contained in this
Agreement or otherwise applicable at such time with respect to Common Stock
owned by the Kleinknecht Shareholders, the Walsh Shareholders, the Servidio
Shareholders and the LSH Shareholders shall again be in effect.

  (c) Concurrently with the consummation of the transfer of Shares pursuant to
this Section 4.02, CSH or the Company, as applicable, shall remit to each of the
Shareholders who have surrendered their certificates the total consideration (by
bank or certified check) for the Shares transferred pursuant hereto and shall
furnish such other evidence of the completion and time of completion of such
transfer and the terms thereof as may be reasonably requested by such
Shareholders.

  (d) In furtherance of, and not in limitation of the foregoing provisions of
this Section 4.02, in connection with a Section 4.02 Sale (which Section 4.02
Sale may be structured as a merger, recapitalization, reorganization, sale of
assets or otherwise) each Kleinknecht Shareholder, Walsh Shareholder, Servidio
Shareholder or LSH Shareholder will (i) consent to and raise no objection
against the Section 4.02 Sale or the process pursuant to which it was arranged,
(ii) waive any appraisal rights and other similar rights and (iii) execute all
documents containing such terms and conditions as those executed by other
Shareholders as directed by the CSH Shareholders.

  (e) The sale of the CSH Shareholders' Shares in any Section 4.02 Sale shall be
effected on the same terms and conditions as the sale of any Shares owned by the
Kleinknecht Shareholders, the Walsh Shareholders, the Servidio Shareholders and
the LSH Shareholders and no CSH Shareholder shall receive any form of special
consideration or control premium in addition to the price payable for the sold
Shares.

                              REGISTRATION RIGHTS

  Section 5.01. Demand Registration. (a) If the Company shall receive a written
request by the CSH Shareholders (any such requesting Person, a "Selling
Shareholder") that the Company effect the registration under the Securities Act
of all or a portion of such Selling Shareholder's Registrable Securities, and
specifying the intended method of disposition thereof, then the Company shall
promptly give written notice of such requested registration (a "Demand
Registration") to the Kleinknecht Shareholders, the Walsh Shareholders, the
Servidio Shareholders and the LSH Shareholders, and thereupon will use its best
efforts to effect, as expeditiously as possible, the registration under the
Securities Act of:

    (i) the Registrable Securities which the Company has been so requested to
  register by the Selling Shareholders, then held by the Selling Shareholders;
  and

    (ii) all other Registrable Securities of the same type as that to which the
  request by the Selling Shareholders relates which any Kleinknecht Shareholder,
  any Walsh Shareholder, any Servidio Shareholder or any LSH Shareholder (all
  such Shareholders, together with the Selling Shareholders, the "Holders") has
  requested the Company to register by written request received by the Company
  within 10 days (one of which shall be a Business Day) after the receipt by
  such Holders of such written notice given by the Company, all to the extent
  necessary to permit the disposition (in accordance with the intended methods
  thereof as aforesaid) of the Registrable Securities so to be registered;
  provided that, subject to Section 5.01(d) hereof, the Company shall not be
  obligated to effect more than five Demand Registrations for the CSH
  Shareholders; and provided further that the Company shall not be obligated to
  effect a Demand Registration unless the aggregate proceeds expected to be
  received from the sale of the Common Stock requested to be included in such
  Demand Registration, in the reasonable opinion of CSH exercised in good faith,
  equals or exceeds $7,500,000. In no event will the Company be required to
  effect more than one Demand Registration within any four-month period.

  (b) Promptly after the expiration of the 10-day period referred to in Section
5.01(a)(ii) hereof, the Company will notify all the Holders to be included in
the Demand Registration of the other Holders and the number of Registrable
Securities requested to be included therein. The Selling Shareholders requesting
a registration under Section 5.01(a) may, at any time prior to the effective
date of the registration statement relating to such registration, revoke such
request, without liability to any of the other Holders, by providing a written
notice to the Company revoking such request, in which case such request, so
revoked, shall be considered a Demand Registration unless such revocation arose
out of the fault of the Company or unless the participating Shareholders
reimburse the Company for all costs incurred by the Company in connection with
such registration, in which case such request shall not be considered a Demand
Registration.

  (c) The Company will pay all Registration Expenses in connection with any
Demand Registration.

  (d) A registration requested pursuant to this Section 5.01 shall not be deemed
to have been effected unless the registration statement relating thereto (i) has
become effective under the Securities Act and (ii) all of the Registrable
Securities registered thereunder have been sold; provided that if, within 180
days after it has become effective, the offering of Registrable Securities
pursuant to such registration is interfered with by any stop order, injunction
or other order or requirement of the SEC or other governmental agency or court
such registration will be deemed not to have been effected.

  (e) If a Demand Registration involves an Underwritten Public Offering and the
managing underwriter shall advise the Company and the Selling Shareholders that,
in its view, (i) the number of shares of Registrable Securities requested to be
included in such registration (including any securities which the Company
proposes to be included which are not Registrable Securities) or (ii) the
inclusion of some or all of the shares of Registrable Securities owned by the
Holders, in any such case, exceeds the largest number of shares which can be
sold without having an adverse effect on such offering, including the price at
which such shares can be sold (the

                                      10



<PAGE>




"Maximum Offering Size"), the Company will include in such registration, in the
priority listed below, up to the Maximum Offering Size:

    (A) first, all Registrable Securities requested to be registered by the
  parties requesting such Demand Registration and all Registrable Securities
  requested to be included in such registration by any other Holder (allocated,
  if necessary for the offering not to exceed the Maximum Offering Size, pro
  rata among such Holders on the basis of the relative number of Registrable
  Securities so requested to be included in such registration); and

    (B) second, any securities proposed to be registered by the Company.

  (f) Upon written notice to each Selling Shareholder, the Company may postpone
effecting a registration pursuant to this Section 5.01 on one occasion during
any period of six consecutive months for a reasonable time specified in the
notice but not exceeding 90 days (which period may not be extended or renewed),
if (1) an investment banking firm of recognized national standing shall advise
the Company and the Selling Shareholders in writing that effecting the
registration would materially and adversely affect an offering of securities of
such Company the preparation of which had then been commenced or (2) the Company
is in possession of material non-public information the disclosure of which
during the period specified in such notice the Company believes, in its
reasonable judgment, would not be in the best interests of the Company.

  (g) After the Company has effected one Demand Registration by the CSH
Shareholders pursuant to this Section 5.01 of Common Stock, the Kleinknecht
Shareholders, upon request of the Kleinknecht Shareholders owning a majority of
the Shares acquired by the Kleinknecht Shareholders on the Closing Date may
request that the Company register Common Stock which are Registrable Securities
then owned by such Kleinknecht Shareholders. In no event will the Company be
required to effect more than two such Demand Registrations by the Kleinknecht
Shareholders. The other provisions of this Article 5 applicable to Demand
Registrations requested by the CSH Shareholders shall apply, mutatis mutandis,
to any such Demand Registration by the Kleinknecht Shareholders.

  (h) If any registration requested pursuant to this Section 5.01 which is
proposed by the Company to be effected by the filing of a registration statement
on form S-3 (or any successor or similar short-form registration statement)
shall be in connection with an Underwritten Public Offering, and if the managing
underwriter shall advise the Company in writing that, in its opinion, the use of
another form of registration statement is of material importance to the success
of such proposed offering, then such registration shall be effected on such
other form.

  Section 5.02. Piggyback Registration. Piggyback Registration. (a) If the
Company proposes to register any of its Common Stock under the Securities Act
(other than pursuant to a Demand Registration), it will each such time,
subject to the provisions of Section 5.02(b) hereof, give prompt written
notice at least 15 days prior to the anticipated filing date of the
registration statement relating to such registration to all Shareholders which
notice shall set forth such Shareholders' rights under this Section 5.02 and
shall offer all Shareholders the opportunity to include in such registration
statement such number of shares of Common Stock as each such Shareholder may
request (a "Piggyback Registration"). Upon the written request of any such
Shareholder made within 10 days after the receipt of notice from the Company
(which request shall specify the number of shares of Common Stock intended to
be disposed of by such Shareholder), the Company will use its reasonable best
efforts to effect the registration under the Securities Act of all shares of
Common Stock which the Company has been so requested to register by such
Shareholders, to the extent requisite to permit the disposition of the shares
of Common Stock so to be registered; provided that (i) if such registration
involves an Underwritten Public Offering, all such Shareholders requesting to
be included in the Company's registration must sell their Registrable
Securities to the underwriters selected as provided in Section 5.04(f) on the
same terms and conditions as apply to the Company or the Selling Shareholder,
as applicable, and (ii) if, at any time after giving written notice of its
intention to register any stock pursuant to this Section 5.02(a) and prior to
the effective date of the registration statement filed in connection with such
registration, the Company shall determine for any reason not to register such
stock, the Company shall give written notice to all such Shareholders and,
thereupon, shall be relieved of its obligation to register any Registrable
Securities in connection with such registration. No

                                      11



<PAGE>




registration effected under this Section 5.02 shall relieve the Company of its
obligations to effect a Demand Registration to the extent required by Section
5.01 hereof. The Company will pay all Registration Expenses in connection with
each registration of Registrable Securities requested pursuant to this Section
5.02.

  (b) If a registration pursuant to this Section 5.02 involves an Underwritten
Public Offering and the managing underwriter advises the Company that, in its
view, the number of shares of Common Stock which the Company and the selling
Shareholders intend to include in such registration exceeds the Maximum Offering
Size, the Company will include in such registration, in the following priority,
up to the Maximum Offering Size:

    (i) first, so much of the Common Stock proposed to be registered for the
  account of the Company as would not cause the offering to exceed the Maximum
  Offering Size; and

    (ii) second, all Registrable Securities requested to be included in such
  registration by any Shareholder pursuant to Section 5.02 (allocated, if
  necessary for the offering not to exceed the Maximum Offering Size, pro rata
  among such Shareholders on the basis of the relative number of shares of
  Registrable Securities so requested to be included in such registration).

  Section 5.03. Holdback Agreements. With respect to each and every firmly
underwritten Public Offering, each Shareholder agrees not to offer or sell any
shares of Common Stock (except for shares of Common Stock, if any, sold in that
Public Offering) during the 14 days prior to the effective date of the
applicable registration statement for a public offering of shares of Common
Stock (except as part of such registration) and during the period after such
effective date equal to the lesser of: (i) 180 days or (ii) any such shorter
period as the Company and the lead managing underwriter of an Underwritten
Public Offering agree.

  Section 5.04. Registration Procedures. Whenever Shareholders request that any
Registrable Securities be registered pursuant to Section 5.01 or 5.02 hereof,
the Company will, subject to the provisions of such Sections, use its reasonable
best efforts to effect the registration and the sale of such Registrable
Securities in accordance with the intended method of disposition thereof as
quickly as practicable, and in connection with any such request:

    (a) The Company will as expeditiously as possible prepare and file with the
  SEC a registration statement on any form selected by counsel for the Company
  and which form shall be available for the sale of the Registrable Securities
  to be registered thereunder in accordance with the intended method of
  distribution thereof, and use its reasonable best efforts to cause such filed
  registration statement to become and remain effective for a period of not less
  than 180 days (or such shorter period in which all of the Registrable
  Securities of the Holders included in such registration statement shall have
  actually been sold thereunder).

    (b) The Company will, if requested, prior to filing a registration statement
  or prospectus or any amendment or supplement thereto, furnish to each
  Shareholder and each underwriter, if any, of the Registrable Securities
  covered by such registration statement copies of such registration statement
  as proposed to be filed, and thereafter the Company will furnish to such
  Shareholder and underwriter, if any, such number of copies of such
  registration statement, each amendment and supplement thereto (in each case
  including all exhibits thereto and documents incorporated by reference
  therein), the prospectus included in such registration statement (including
  each preliminary prospectus) and such other documents as such Shareholder or
  underwriter may reasonably request in order to facilitate the disposition of
  the Registrable Securities owned by such Shareholder. Each Shareholder shall
  have the right to request that the Company modify any information contained in
  such registration statement, amendment and supplement thereto pertaining to
  such Shareholder and the Company shall use its reasonable best efforts to
  comply with such request, provided, however, that the Company shall not have
  any obligation to so modify any information if so doing would cause the
  prospectus to 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 not misleading.

    (c) After the filing of the registration statement, the Company will (i)
  cause the related prospectus to be supplemented by any required prospectus
  supplement, and as so supplemented to be filed pursuant to

                                      12



<PAGE>




  Rule 424 under the Securities Act, (ii) comply with the provisions of the
  Securities Act with respect to the disposition of all Registrable Securities
  covered by such registration statement during the applicable period in
  accordance with the intended methods of disposition by the sellers thereof set
  forth in such registration statement or supplement to such prospectus and
  (iii) promptly notify each Shareholder holding Registrable Securities covered
  by such registration statement of any stop order issued or threatened by the
  SEC or any state securities commission under state blue sky laws and take all
  reasonable actions required to prevent the entry of such stop order or to
  remove it if entered.

    (d) The Company will use its reasonable best efforts to (i) register or
  qualify the Registrable Securities covered by such registration statement
  under such other securities or blue sky laws of such jurisdictions in the
  United States as any Shareholder holding such Registrable Securities
  reasonably (in light of such Shareholder's intended plan of distribution)
  requests and (ii) cause such Registrable Securities 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 and do any
  and all other acts and things that may be reasonably necessary or advisable to
  enable such Shareholder to consummate the disposition of the Registrable
  Securities owned by such Shareholder; provided that the Company will not be
  required to (A) qualify generally to do business in any jurisdiction where it
  would not otherwise be required to qualify but for this paragraph (d), (B)
  subject itself to taxation in any such jurisdiction or (C) consent to general
  service of process in any such jurisdiction.

    (e) The Company will immediately notify each Shareholder holding such
  Registrable Securities covered by such registration statement, 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
  not misleading and promptly prepare and make available to each such
  Shareholder and file with the SEC any such supplement or amendment.

    (f) In connection with any Demand Registration requested by the CSH
  Shareholders, the Company shall appoint the underwriter or underwriters chosen
  by CSH. The Company will 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, including the engagement of a "qualified independent
  underwriter" in connection with the qualification of the underwriting
  arrangements with the NASD.

    (g) Upon execution of confidentiality agreements in form and substance
  reasonably satisfactory to the Company, the Company will make available for
  inspection by any Shareholder and any underwriter participating in any
  disposition pursuant to a registration statement being filed by the Company
  pursuant to this Section 5.04 and any attorney, accountant or other
  professional retained by any such Shareholder or underwriter (collectively,
  the "Inspectors"), all financial and other records, pertinent corporate
  documents and properties of the Company (collectively, the "Records") as shall
  be reasonably requested by any such Person, and cause the Company's officers,
  directors and employees to supply all information reasonably requested by any
  Inspectors in connection with such registration statement.

    (h) The Company will furnish to each such Shareholder (if requested by such
  Shareholder) and to each such underwriter, if any, a signed counterpart,
  addressed to such underwriter and the participating Shareholders, of (i) an
  opinion or opinions of counsel to the Company and (ii) a comfort letter or
  comfort letters from the Company's independent public accountants, each in
  customary form and covering such matters of the type customarily covered by
  opinions or comfort letters, as the case may be, as a majority of such
  Shareholders or the managing underwriter therefor reasonably requests.

    (i) The Company will otherwise use its reasonable best efforts to comply
  with all applicable rules and regulations of the SEC and the relevant state
  blue sky commissions, and make available to its securityholders, as soon as
  reasonably practicable, an earnings statement covering a period of 12 months,

                                      13



<PAGE>




  beginning within three months after the effective date of the registration
  statement, which earnings statement shall satisfy the provisions of Section
  11(a) of the Securities Act.

    (j) The Company may require each such Shareholder to promptly furnish in
  writing to the Company information regarding the distribution of the
  Registrable Securities as the Company may from time to time reasonably request
  and such other information as may be legally required in connection with such
  registration.

    (k) Each such Shareholder agrees that, upon receipt of any notice from the
  Company of the happening of any event of the kind described in Section 5.04(e)
  hereof, such Shareholder will forthwith discontinue disposition of Registrable
  Securities pursuant to the registration statement covering such Registrable
  Securities until such Shareholder's receipt of the copies of the supplemented
  or amended prospectus contemplated by Section 5.04(e) hereof, and, if so
  directed by the Company, such Shareholder will deliver to the Company all
  copies, other than any permanent file copies then in such Shareholder's
  possession, of the most recent prospectus covering such Registrable Securities
  at the time of receipt of such notice. In the event that the Company shall
  give such notice, the Company shall extend the period during which such
  registration statement shall be maintained effective (including the period
  referred to in Section 5.04(a) hereof) by the number of days during the period
  from and including the date of the giving of notice pursuant to Section
  5.04(e) hereof to the date when the Company shall make available to such
  Shareholder a prospectus supplemented or amended to conform with the
  requirements of Section 5.04(e) hereof.

    (l) The Company will use its reasonable best efforts to list such
  Registrable Securities on any securities exchange on which the Common Stock is
  then listed or on NASDAQ if the Common Stock is then quoted on NASDAQ not
  later than the effective date of such registration statement.

  Section 5.05. Indemnification by the Company. The Company agrees to indemnify
and hold harmless each Shareholder holding Registrable Securities covered by a
registration statement, its officers, directors, employees, members, partners
and agents, any affiliate of such Shareholder and each Person, if any, who
controls such Shareholder within the meaning of the Securities Act or Section 20
of the Exchange Act (and officers, directors, employees, members, partners and
agents of any such affiliate or controlling Persons) from and against any and
all losses, claims, damages and liabilities, joint or several, and expenses
(including reasonable attorneys fees and costs and expenses of investigation)
caused by any untrue statement or alleged untrue statement of a material fact
contained in any registration statement or prospectus relating to the
Registrable Securities (as amended or supplemented if the Company shall have
furnished any amendments or supplements thereto) or any preliminary prospectus,
or caused by 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 or liabilities are
caused by any such untrue statement or omission or alleged untrue statement or
omission so made in strict conformity with information furnished in writing to
the Company by such Shareholder or on such Shareholder's behalf expressly for
use therein; provided that with respect to any untrue statement or omission or
alleged untrue statement or omission made in any preliminary prospectus, or in
any prospectus, as the case may be, 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
(or, in the case of a prospectus, the prospectus as amended or supplemented) 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
Company has provided such current copy of such prospectus (or such amended or
supplemented prospectus, as the case may be) to such Shareholder in a timely
manner prior to such sale and it was the responsibility of such Shareholder
under the Securities Act to provide such Person with a current copy of the
prospectus (or such amended or supplemented prospectus, as the case may be) and
such current copy of the prospectus (or such amended or supplemented prospectus,
as the case may be) would have cured the defect giving rise to such loss, claim,
damage, liability or expense. The Company also agrees to indemnify any
underwriters of the Registrable Securities, their officers and directors and
each person who controls such underwriters on substantially the same basis as
that of the indemnification of the Shareholders provided in this Section 5.05.


                                      14



<PAGE>




  Section 5.06. Indemnification by Participating Shareholders. Each Shareholder
holding Registrable Securities included in any registration statement agrees,
severally but not jointly, to indemnify and hold harmless the Company, its
officers, directors and agents and each Person (other than such Shareholder) if
any, who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company to such Shareholder, but only (i) with
respect to information furnished in writing by such Shareholder or on such
Shareholder'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 or (ii) to the extent that any
loss, claim, damage, liability or expense described in Section 5.05 results from
the fact that a current copy of the prospectus (or, in the case of a prospectus,
the prospectus as amended or supplemented) 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 it was the responsibility of such Shareholder to
provide such Person with a current copy of the prospectus (or such amended or
supplemented prospectus, as the case may be) and such current copy of the
prospectus (or such amended or supplemented prospectus, as the case may be)
would have cured the defect giving rise to such loss, claim, damage, liability
or expense. Each such Shareholder shall be prepared, if required by the
underwriting agreement, to indemnify and hold harmless underwriters of the
Registrable Securities, their officers and directors and each person who
controls such underwriters on substantially the same basis as that of the
indemnification of the Company provided in this Section 5.06. As a condition to
including Registrable Securities in any registration statement filed in
accordance with Article 5 hereof, the Company may require that it shall have
received an undertaking reasonably satisfactory to it from any underwriter to
indemnify and hold it harmless to the extent customarily provided by
underwriters with respect to similar securities.

  No Shareholder shall be liable under Section 5.06 for any damage thereunder in
excess of the net proceeds realized by such Shareholder in the sale of the
Registrable Securities of such Shareholder.

  Section 5.07. Conduct of Indemnification Proceedings. In case any proceeding
(including any governmental investigation) shall be instituted involving any
Person in respect of which indemnity may be sought pursuant to this Article 5,
such Person (an "Indemnified Party") shall promptly notify the Person against
whom such indemnity may be sought (the "Indemnifying Party") in writing and the
Indemnifying Party shall assume the defense thereof, including the employment of
counsel reasonably satisfactory to such Indemnified Party, and shall assume the
payment of all fees and expenses; provided that the failure of any Indemnified
Party so to notify the Indemnifying Party shall not relieve the Indemnifying
Party of its obligations hereunder except to the extent that the Indemnifying
Party is materially and actually prejudiced by such failure to notify. In any
such proceeding, any Indemnified Party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Party unless (i) the Indemnifying Party and the Indemnified
Party shall have mutually agreed to the retention of such counsel or (ii) in the
reasonable judgment of such Indemnified Party representation of both parties by
the same counsel would be inappropriate due to actual or potential differing
interests between them. It is understood that the Indemnifying Party shall not,
in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys (in addition to any local counsel) at any time for
all such Indemnified Parties, and that all such fees and expenses shall be
reimbursed as they are incurred. In the case of any such separate firm for the
Indemnified Parties, such firm shall be designated in writing by the Indemnified
Parties. The Indemnifying Party shall not be liable for any settlement of any
proceeding effected without its written consent, but if settled with such
consent, or if there be a final judgment for the plaintiff, the Indemnifying
Party shall indemnify and hold harmless such Indemnified Parties from and
against any and all losses, claims, damages, liabilities and expenses or
liability (to the extent stated above) by reason of such settlement or judgment.
No Indemnifying Party shall, without the prior written consent of the
Indemnified Party, effect any settlement of any pending or threatened proceeding
in respect of which any Indemnified Party is or could have been a party and
indemnity could have been sought hereunder by such Indemnified Party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability arising out of such proceeding.

  Section 5.08. Contribution. If the indemnification provided for in this
Article 5 is held by a court of competent jurisdiction to be unavailable to the
Indemnified Parties in respect of any losses, claims, damages, liabilities or
expenses referred to herein, 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, claims, damages or
liabilities (i) as between the Company and the Shareholders holding Registrable
Securities covered by a registration statement and their related Indemnified
Parties on the one hand and the underwriters and their related Indemnified
Parties on the other, in such proportion as is appropriate to reflect the
relative benefits received by the Company and such Shareholders on the one hand
and the underwriters on the other, from the offering of the Shareholders'
Registrable Securities, or if such allocation is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits but also the relative fault of the Company and such Shareholders on the
one hand and of such underwriters on the other in connection with the statements
or omissions which resulted in such losses, claims, damages or liabilities, as
well as any other relevant equitable considerations and (ii) as between the
Company and their related Indemnified Parties on the one hand and each such
Shareholder and their related Indemnified Parties on the other, in such
proportion as is appropriate to reflect the relative fault of the Company and of
each such Shareholder in connection with such statements or omissions, as well
as any other relevant equitable considerations. The relative benefits received
by the Company and such Shareholders on the one hand and such underwriters 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 such Shareholders bear to the
total underwriting discounts and commissions received by such underwriters, in
each case as set forth in the table on the cover page of the prospectus. The
relative fault of the Company and such Shareholders on the one hand and of such
underwriters 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 such Shareholders or by such underwriters. The
relative fault of the Company on the one hand and of each such Shareholder 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 Shareholders agree that it would not be just and equitable
if contribution pursuant to this Section 5.08 were determined by pro rata
allocation 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 Indemnified Party as a result of the losses,
claims, damages, liabilities or expenses 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.
Notwithstanding the provisions of this Section 5.08 no underwriter shall be
required to contribute any amount in excess of the underwriting discount
applicable to securities purchased by such underwriter in such offering, less
the aggregate amount of any damages which such underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission, and no Shareholder shall be required to contribute any
amount in excess of the amount by which the net proceeds realized on the sale of
the Registrable Securities of such Shareholder exceeds the amount of any damages
which such Shareholder 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. Each Shareholder's obligation
to contribute pursuant to this Section 5.08 is several in the proportion that
the proceeds of the offering received by such Shareholder bears to the total
proceeds of the offering received by all such Shareholders and not joint.

  Section 5.09. Participation in Public Offering. No Person may participate in
any Underwritten Public Offering hereunder unless such Person (a) agrees to sell
such Person's securities on the basis provided in any underwriting arrangements
to be entered into in connection with such Underwritten Public Offering and (b)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other

                                      16

documents reasonably required under the terms of such underwriting arrangements
and the provisions of this Agreement in respect of registration rights.

  Section 5.10. Rule 144. The Company covenants that it will file the reports
required to be filed by it under the Securities Act and the Exchange Act and the
rules and regulations adopted by the SEC thereunder (or, if the Company is not
required to file such reports, it will, upon the request of any holder of
Registrable Securities, make publicly available such information), and it will
take such further action as any holder of Registrable Securities may reasonably
request, all to the extent required from time to time to enable such holder to
sell shares of Registrable Securities without registration under the Securities
Act within the limitation of the exemptions provided by (i) Rule 144 under the
Securities Act, as such Rule may be amended from time to time, or (ii) any
similar rule or regulation hereafter adopted by the SEC. Upon the request of any
holder of Registrable Securities, the Company will deliver to such holder a
written statement as to whether it has complied with such requirements.
Notwithstanding anything contained in this Section 5.10, the Company may
de-register under Section 12 of the Exchange Act if it then is permitted to do
so pursuant to the Exchange Act and the rules and regulations thereunder and, in
such circumstances, shall not be required hereby to file any reports which may
be necessary in order for Rule 144 or any similar rule or regulation to be
available.

  Section 5.11. No Transfer of Registration Rights. None of the rights of
Shareholders under this Article 5 shall be assignable by any Shareholder to any
Person acquiring securities of such Shareholder in any Public Offering or
pursuant to a distribution to the public under Rule 144 under the Securities
Act.

written consent of Shareholders holding at least 51% of the Shares held by all
Shareholders, the Company shall not enter into any agreement with any holder or
prospective holder of any securities of the Company (a) that would allow such
holder or prospective holder to include such securities in any registration
filed pursuant to Section 5.01 or 5.02 hereof, unless under the terms of such
agreement, such holder or prospective holder may include such securities in any
such registration only to the extent that the inclusion of such securities would
not reduce the amount of the Registrable Securities of the Shareholders included
therein or (b) on terms otherwise more favorable than this Agreement.

  Section 6.02. Limitation on Purchase of Common Stock. Until the earlier to
occur of (i) the fifth anniversary of the Closing Date or (ii) the occurrence of
a Change in Control no Kleinknecht Shareholder shall acquire any shares of
Common Stock or securities convertible into or exercisable or exchangeable for
Common Stock except (x) as a Permitted Transferee in a transfer from any other
Kleinknecht Shareholder which is otherwise permitted under the terms of Article
3 hereof or (y) pursuant to stock options granted by the Company.

implied, is intended to confer on any Person other than the parties hereto, and

Agreement shall execute and deliver to the Company a Joinder Agreement, and (ii)

of which when executed shall be deemed to be an original but all of which taken
together shall constitute one and the same agreement.

damage would occur in the event that any of the provisions of this Agreement

any New York State court sitting in New York, New York, and each of the parties
hereby consents to the exclusive jurisdiction of such courts (and of the
appropriate appellate courts therefrom) in any such suit, action or proceeding
and irrevocably waives, to the fullest extent permitted by law, any objection
which it may now or hereafter have to the laying of the venue of any such suit,
action or proceeding in any such court or that any such suit, action or
proceeding which is brought in any such court has been brought in an
inconvenient forum. Process in any such suit, action or proceeding may be served
on any party anywhere in the world, whether within or without the jurisdiction
of any such court. Without limiting the foregoing, each party agrees that
service of process on such party by any method provided in Section 7.05 shall be

the party that does not prevail.

remain in full force and effect so long as the economic or legal substance of

shall negotiate in good faith to modify this Agreement so as to effect the

                                   ARTICLE II

                        AMOUNTS AND TERMS OF THE ADVANCES
                            AND THE LETTERS OF CREDIT

                  SECTION 2.01. THE ADVANCES AND LETTERS OF CREDIT. (a) THE
WORKING CAPITAL ADVANCES. Each Lender severally agrees, on the terms and
conditions hereinafter set forth, to make advances (each a "WORKING CAPITAL
ADVANCE") to either Borrower from time to time on any Business Day during the
period from the Effective Date until the Termination Date in an amount for each
such Advance not to exceed (i) in the case of the Parent Borrower, the lesser of
(x) such Lender's Unused Working Capital Commitment at such time and (y) such
Lender's Pro Rata Share of the Loan Value of the applicable Eligible Collateral
at such time, and (ii) in the case of the Sub Borrower, the lesser of (x) such
Lender's Unused Working Capital Commitment at such time and (y) such Lender's
Pro Rata Share of the Loan Value of the applicable Eligible Collateral at such
time; PROVIDED, HOWEVER, that notwithstanding the foregoing, no Advances shall
be made hereunder until the condition set forth in Section 5.01(q)(vii) shall
have been satisfied in a manner reasonably acceptable to the Administrative
Agent. Each Borrowing shall be in an aggregate amount of $1,000,000 or an
integral multiple of $100,000 in excess thereof and shall consist of Working
Capital Advances made simultaneously by the Lenders ratably according to their
Working Capital Commitments. Within the limits of each Lender's Unused Working
Capital Commitment in effect from time to time, the Borrowers may borrow under
this Section 2.01(a), prepay pursuant to Section 2.06(a) and reborrow under this
Section 2.01(a).

                  (b) LETTERS OF CREDIT. The Issuing Bank agrees, on the terms
and conditions hereinafter set forth, to issue letters of credit (the "LETTERS
OF CREDIT") for the account of the Parent Borrower from time to time on any
Business Day during the period from the Effective Date until 60 days before the
Termination Date (i) in an aggregate Available Amount for all Letters of Credit
not to exceed at any time the Issuing Bank's Letter of Credit Commitment at such
time and (ii) in an Available Amount for each such Letter of Credit not to
exceed the lesser of (x) the Unused Working Capital Commitments of the Lenders
at such time and (y) the Loan Value of the applicable Eligible Collateral at
such time. No Letter of Credit shall have an expiration date (including all
rights of the Parent Borrower or the beneficiary to require renewal) later than
the earlier of 30 days before the Termination Date and (A) in the case of
Standby Letters of Credit, one year after the date of issuance thereof and (B)
in the case of a Trade Letter of Credit, 60 days after the date of issuance
thereof; PROVIDED, HOWEVER, that notwithstanding the foregoing, (x) no Letters
of Credit shall be issued hereunder after the Effective Date until the condition
set forth in Section 5.01(q)(vii) shall have been satisfied in a manner
reasonably acceptable to the Administrative Agent and (y) no Letters of Credit
shall be issued hereunder after the Effective Date (unless the Initial Issuing
Bank otherwise agrees) until the Initial Issuing Bank shall have assigned its
Letter of Credit Commitment to an Eligible Assignee acceptable to it and the
Letters of Credit issued on the Effective Date shall have been replaced by
Letters of Credit issued by such Eligible Assignee or shall have otherwise
expired or terminated. Within the limits of the Letter of Credit Facility, and
subject to the limits referred to above, the Parent Borrower may request the
issuance of Letters of Credit under this Section 2.01(b), repay any Letter of
Credit Advances resulting from drawings thereunder pursuant to Section 2.03(c)
and request the issuance of additional Letters of Credit under this Section
2.01(b).

                  SECTION 2.02.  MAKING THE ADVANCES.  (a)  Except as
otherwise provided in Section 2.03, each Borrowing shall be made on notice,
given not later than 11:00 A.M. (New York City time) on the



<PAGE>


                                       30

third Business Day prior to the date of the proposed Borrowing in the case of a
Borrowing consisting of Eurodollar Rate Advances, or the first Business Day
prior to the date of the proposed Borrowing in the case of a Borrowing
consisting of Base Rate Advances, by the applicable Borrower to the
Administrative Agent, which shall give to each Lender prompt notice thereof by
telex or telecopier. Each such notice of a Borrowing (a "NOTICE OF BORROWING")
shall be by telephone, confirmed immediately in writing, or telex or telecopier,
in substantially the form of Exhibit B hereto, specifying therein the requested
(i) date of such Borrowing, (ii) Type of Advances comprising such Borrowing,
(iii) aggregate amount of such Borrowing and (iv) in the case of a Borrowing
consisting of Eurodollar Rate Advances, initial Interest Period for each such
Advance. Each Lender shall, before 11:00 A.M. (New York City time) on the date
of such Borrowing, make available for the account of its Applicable Lending
Office to the Administrative Agent at the Administrative Agent's Account, in
same day funds, such Lender's ratable portion of such Borrowing in accordance
with the respective Working Capital Commitments of such Lender and the other
Lenders. After the Administrative Agent's receipt of such funds and upon
fulfillment of the applicable conditions set forth in Article III, the
Administrative Agent shall make such funds available to such Borrower by
crediting the Parent Borrower's Account or the Sub Borrower's Account, as
applicable; PROVIDED, HOWEVER, that the Administrative Agent shall first make a
portion of such funds equal to the aggregate principal amount of any Letter of
Credit Advances made by the Issuing Bank and by any other Lender and outstanding
on the date of such Borrowing, plus interest accrued and unpaid thereon to and
as of such date, available to the Issuing Bank and such other Lenders for
repayment of such Letter of Credit Advances.

                  (b) Anything in subsection (a) of this Section 2.02 to the
contrary notwithstanding, (i) neither Borrower may select Eurodollar Rate
Advances for any Borrowing if the aggregate amount of such Borrowing is less
than $3,000,000 or if the obligation of the Lenders to make Eurodollar Rate
Advances shall then be suspended pursuant to Section 2.09 or 2.10 and (ii) the
Working Capital Advances may not be outstanding as part of more than 12 separate
Borrowings.

                  (c) Each Notice of Borrowing shall be irrevocable and binding
on the Borrower giving such Notice of Borrowing. In the case of any Borrowing
that the related Notice of Borrowing specifies is to be comprised of Eurodollar
Rate Advances, the applicable Borrower shall indemnify each Lender against any
loss, cost or expense incurred by such Lender as a result of any failure to
fulfill on or before the date specified in such Notice of Borrowing for such
Borrowing the applicable conditions set forth in Article III, including, without
limitation, any loss (including loss of anticipated profits), cost or expense
incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by such Lender to fund the Advance to be made by such Lender as part of
such Borrowing when such Advance, as a result of such failure, is not made on
such date.

                  (d) Unless the Administrative Agent shall have received notice
from a Lender prior to the date of any Borrowing that such Lender will not make
available to the Administrative Agent such Lender's ratable 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 subsection (a) of this Section 2.02 and the Administrative Agent
may, in reliance upon such assumption, make available to the applicable Borrower
on such date a corresponding amount. If and to the extent that such Lender shall
not have so made such ratable portion available to the Administrative Agent,
such Lender and such Borrower severally agree to repay or pay to the
Administrative Agent forthwith on demand such corresponding amount and to pay
interest thereon, for each day from the date such amount is made available to
such Borrower until the date such amount is repaid or paid to the Administrative
Agent, at



<PAGE>


                                       31

(i) in the case of such Borrower, the interest rate applicable at such time
under Section 2.07 to Advances comprising such Borrowing and (ii) in the case of
such Lender, the Federal Funds Rate. If such Lender shall pay to the
Administrative Agent such corresponding amount, such amount so paid shall
constitute such Lender's Advance as part of such Borrowing for all purposes.

                  (e) The failure of any Lender to make the Advance to be made
by it as part of any Borrowing shall not relieve any other Lender of its
obligation, if any, hereunder to make its Advance on the date of such Borrowing,
but no Lender shall be responsible for the failure of any other Lender to make
the Advance to be made by such other Lender on the date of any Borrowing.

                  SECTION 2.03. ISSUANCE OF AND DRAWINGS AND REIMBURSEMENT UNDER
LETTERS OF CREDIT. (a) REQUEST FOR ISSUANCE. Each Letter of Credit shall be
issued upon notice, given not later than 11:00 A.M. (New York City time) on the
fifth Business Day prior to the date of the proposed issuance of such Letter of
Credit, by the Parent Borrower to the Issuing Bank, which shall give to the
Administrative Agent and each Lender prompt notice thereof by telex or
telecopier. Each such notice of issuance of a Letter of Credit (a "NOTICE OF
ISSUANCE") shall be by telephone, confirmed immediately in writing, or telex or
telecopier, specifying therein the requested (A) date of such issuance (which
shall be a Business Day), (B) Available Amount of such Letter of Credit, (C)
expiration date of such Letter of Credit, (D) name and address of the
beneficiary of such Letter of Credit and (E) form of such Letter of Credit, and
shall be accompanied by such application and agreement for letter of credit as
the Issuing Bank may specify to the Parent Borrower for use in connection with
such requested Letter of Credit (a "LETTER OF CREDIT AGREEMENT"). If (x) the
requested form of such Letter of Credit is acceptable to the Issuing Bank in its
sole discretion and (y) the Issuing Bank has not received notice from the
Administrative Agent or the Required Lenders that the conditions to issuing such
Letter of Credit have not been satisfied or duly waived, the Issuing Bank shall,
upon fulfillment of the applicable conditions set forth in Article III, make
such Letter of Credit available to the Parent Borrower at its office referred to
in Section 8.02 or as otherwise agreed with the Parent Borrower in connection
with such issuance. In the event and to the extent that the provisions of any
Letter of Credit Agreement shall conflict with this Agreement, the provisions of
this Agreement shall govern. At the Parent Borrower's request, the Issuing Bank
shall provide the Parent Borrower with a copy of the form of Letter of Credit to
be issued for the Parent Borrower's review and approval prior to issuance.

                  (b) LETTER OF CREDIT REPORTS. The Issuing Bank shall furnish
(A) to the Administrative Agent on the first Business Day of each week a written
report summarizing issuance and expiration dates of Letters of Credit issued
during the previous week and drawings during such week under all Letters of
Credit, (B) to each Lender on the first Business Day of each month a written
report summarizing issuance and expiration dates of Letters of Credit issued
during the preceding month and drawings during such month under all Letters of
Credit and (C) to the Administrative Agent and each Lender on the first Business
Day of each calendar quarter a written report setting forth the average daily
aggregate Available Amount during the preceding calendar quarter of all Letters
of Credit.

                  (c) DRAWING AND REIMBURSEMENT. The payment by the Issuing Bank
of a draft drawn under any Letter of Credit shall constitute for all purposes of
this Agreement the making by the Issuing Bank of a Letter of Credit Advance,
which shall be a Base Rate Advance, in the amount of such draft. Upon written
demand by the Issuing Bank, with a copy of such demand to the Administrative
Agent, each Lender shall purchase from the Issuing Bank, and the Issuing Bank
shall sell and assign to each such



<PAGE>


                                       32

Lender, such Lender's Pro Rata Share of such outstanding Letter of Credit
Advance as of the date of such purchase, by making available for the account of
its Applicable Lending Office to the Administrative Agent for the account of the
Issuing Bank, by deposit to the Administrative Agent's Account, in same day
funds, an amount equal to the portion of the outstanding principal amount of
such Letter of Credit Advance to be purchased by such Lender. Promptly after
receipt thereof, the Administrative Agent shall transfer such funds to the
Issuing Bank. The Parent Borrower hereby agrees to each such sale and
assignment. Each Lender agrees to purchase its Pro Rata Share of an outstanding
Letter of Credit Advance on (i) the Business Day on which demand therefor is
made by the Issuing Bank; PROVIDED that notice of such demand is given not later
than 11:00 A.M. (New York City time) on such Business Day or (ii) the first
Business Day next succeeding such demand if notice of such demand is given after
such time. Upon any such assignment by the Issuing Bank to any Lender of a
portion of a Letter of Credit Advance, the Issuing Bank represents and warrants
to such other Lender that the Issuing Bank is the legal and beneficial owner of
such interest being assigned by it, free and clear of any Liens, but makes no
other representation or warranty and assumes no responsibility with respect to
such Letter of Credit Advance, the Loan Documents or any Loan Party. If and to
the extent that any Lender shall not have so made the amount of such Letter of
Credit Advance available to the Administrative Agent, such Lender agrees to pay
to the Administrative Agent forthwith on demand such amount together with
interest thereon, for each day from the date of demand by the Issuing Bank until
the date such amount is paid to the Administrative Agent, at the Federal Funds
Rate for its account or the account of the Issuing Bank, as applicable. If such
Lender shall pay to the Administrative Agent such amount for the account of the
Issuing Bank on any Business Day, such amount so paid in respect of principal
shall constitute a Letter of Credit Advance made by such Lender on such Business
Day for purposes of this Agreement, and the outstanding principal amount of the
Letter of Credit Advance made by the Issuing Bank shall be reduced by such
amount on such Business Day.

                  (d) FAILURE TO MAKE LETTER OF CREDIT ADVANCES. The failure of
any Lender to make the Letter of Credit Advance to be made by it on the date
specified in Section 2.03(c) shall not relieve any other Lender of its
obligation hereunder to make its Letter of Credit Advance on such date, but no
Lender shall be responsible for the failure of any other Lender to make the
Letter of Credit Advance to be made by such other Lender on such date.

                  SECTION 2.04. REPAYMENT OF ADVANCES. (a) WORKING CAPITAL
ADVANCES. Each Borrower shall repay to the Administrative Agent for the ratable
account of the Lenders on the Termination Date the aggregate outstanding
principal amount of the Working Capital Advances then outstanding and owing by
such Borrower.

                  (b) LETTER OF CREDIT ADVANCES. (i) The Parent Borrower shall
repay to the Administrative Agent for the account of the Issuing Bank and each
other Lender that has made a Letter of Credit Advance on the earlier of demand
and the Termination Date the outstanding principal amount of
each Letter of Credit Advance made by each of them.

                  (ii) The Obligations of the Parent Borrower under this
Agreement, any Letter of Credit Agreement and any other agreement or instrument
relating to any Letter of Credit shall be unconditional and irrevocable, and
shall be paid strictly in accordance with the terms of this Agreement, such
Letter of Credit Agreement and such other agreement or instrument under all
circumstances, including, without limitation, the following circumstances (it
being understood that any such payment by the Parent Borrower is without
prejudice to, and does not constitute a waiver of, any rights that the Parent
Borrower might have

                  (B) any change in the time, manner or place of payment of, or

         Borrower in respect of any L/C Related Document or any other amendment
         or waiver of or any consent to departure from all or any of the L/C
         Related
         Documents;

                  (C) the existence of any claim, setoff, defense or other right
         that the Parent Borrower may have at any time against any beneficiary
         or any transferee of a Letter of Credit (or any Persons for whom any
         such beneficiary or any such transferee may be acting), the Issuing
         Bank or any other Person, whether in connection with the transactions
         contemplated by the L/C Related Documents or any unrelated transaction;

                  (D) any statement or any 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;

                  (E) payment by the Issuing Bank under a Letter of Credit
         against presentation of a draft or certificate that does not strictly
         comply with the terms of such Letter of Credit;

                  (F) any exchange, release or non-perfection of any Collateral
         or other collateral, or any release or amendment or waiver of or
         consent to departure from the Domestic Guaranty or any other guarantee,
         for all or any of the Obligations of the Parent Borrower in respect of
         the L/C Related Documents; or

                  (G) any other circumstance or happening whatsoever, whether or
         not similar to any of the foregoing, including, without limitation, any
         other circumstance that might otherwise constitute a defense available
         to, or a discharge of, the Parent Borrower or a Domestic Guarantor
         or any other guarantor.

                  SECTION 2.05. TERMINATION OR REDUCTION OF THE COMMITMENTS. (a)
OPTIONAL. The Parent Borrower may, upon at least five Business Days' notice to
the Administrative Agent, terminate in whole or reduce in part the unused

reduced from time to time on the date of each reduction in the Working Capital
Facility by the amount, if any, by which the amount of the Letter of Credit

upon at least five Business Days' notice to the Administrative Agent stating the
proposed date and aggregate principal amount of the prepayment, and if such

Collateral on such Business Day.

                  (iii) The Parent Borrower shall, on each Business Day, pay to
the Administrative Agent for deposit in the L/C Cash Collateral Account an
amount sufficient to cause the aggregate amount on deposit in such Account to
equal the amount by which the aggregate Available Amount of all Letters of
Credit then outstanding exceeds the Letter of Credit Facility on such Business
Day.

                  (iv) Prepayments of the Working Capital Facility made pursuant
to clause (i) or (ii) of this Section 2.06(b) shall be FIRST applied to prepay
Letter of Credit Advances then outstanding until such Advances are paid in full,
SECOND applied to prepay Working Capital Advances then outstanding comprising
part of the same Borrowings until such Advances are paid in full and THIRD
deposited in the L/C Cash Collateral Account to cash collateralize 100% of the
Available Amount of the Letters of Credit then outstanding; and, in the case of
prepayments of the Working Capital Facility required pursuant to clause (i)
above, the amount remaining (if any) after the prepayment in full of the
Advances then outstanding and the 100% cash collateralization of the aggregate
Available Amount of Letters of Credit then outstanding (the sum of such
prepayment amounts, cash collateralization amounts and remaining amount being
referred to herein as the "REDUCTION AMOUNT") may be retained by the Parent
Borrower and the Working Capital Facility shall be permanently reduced as set
forth in Section 2.05(b)(i). Upon the drawing of any Letter of Credit for which
funds are on deposit in the L/C Cash Collateral Account, such funds shall be
applied to reimburse the Issuing Bank or Lenders, as applicable.

                  (v) All prepayments under this subsection (b) shall be made
together with accrued interest to the date of such prepayment on the principal
amount prepaid.

                  SECTION 2.07.  INTEREST.  (a)  SCHEDULED INTEREST.  Each
Borrower shall pay interest on the unpaid principal amount of each Advance owing
by such Borrower to each Lender from the date of such Advance until such
principal amount shall be paid in full, at the following rates per annum:

                  (i) BASE RATE ADVANCES. During such periods as such Advance is
         a Base Rate Advance, a rate per annum equal at all times to the sum of
         (A) the Base Rate in effect from time to time PLUS (B) the Applicable
         Margin in effect from time to time, payable in arrears quarterly on the
         last day of each March, June, September and December during such
         periods and on the date such Base Rate Advance shall be Converted or
         paid in full.

                  (ii) EURODOLLAR RATE ADVANCES. During such periods as such
         Advance is a Eurodollar Rate Advance, a rate per annum equal at all
         times during each Interest Period for such Advance to the sum of (A)
         the Eurodollar Rate for such Interest Period for such Advance PLUS (B)
         the Applicable Margin in effect on the first day of such Interest
         Period, payable in arrears on the last day of such Interest Period and,
         if such Interest Period has a duration of more than three months, on
         each day that occurs during such Interest Period every three months
         from the first day of such Interest Period and on the date such
         Eurodollar Rate Advance shall be Converted or paid in full.

                                       36

                  (b) DEFAULT INTEREST. Upon the occurrence and during the
continuance of an Event of Default, each Borrower shall pay interest on (i) the
unpaid principal amount of each Advance owing by such Borrower to each Lender,
payable in arrears on the dates referred to in clause (a)(i) or (a)(ii) of this
Section 2.07 and on demand, at a rate per annum equal at all times to 2% per
annum above the rate per annum required to be paid on such Advance pursuant to
clause (a)(i) or (a)(ii) of this Section 2.07 and (ii) to the fullest extent
permitted by law, the amount of any interest, fee or other amount payable
hereunder that is not paid when due, from the date such amount shall be due
until such amount shall be paid in full, payable in arrears on the date such
amount shall be paid in full and on demand, at a rate per annum equal at all
times to 2% per annum above the rate per annum required to be paid, in the case
of interest, on the Type of Advance on which such interest has accrued pursuant
to clause (a)(i) or (a)(ii) of this Section 2.07, and, in all other cases, on
Base Rate Advances pursuant to clause (a)(i) of this Section 2.07.

                  (c) NOTICE OF INTEREST RATE. Promptly after receipt of a
Notice of Borrowing pursuant to Section 2.02(a), the Administrative Agent shall
give notice to the Borrower giving such Notice of Borrowing and each Lender of
the applicable interest rate determined by the Administrative Agent for
purposes of Section 2.07(a)(i) or 2.07(a)(ii).

                  SECTION 2.08.  FEES.  (a)  COMMITMENT FEE.  The Parent 
Borrower shall pay to the Administrative Agent for the account of the Lenders a
commitment fee, from the date hereof in the case of each Initial Lender and from
the effective date specified in the Assignment and Acceptance pursuant to which
it became a Lender in the case of each other Lender until the Termination Date,
payable in arrears on the date of the initial Borrowing hereunder, and
thereafter quarterly on the last Business Day of each March, June, September and
December, commencing June 30, 1998, and on the Termination Date, at the rate of
0.50% per annum on the daily aggregate Unused Working Capital Commitment of such
Lender; PROVIDED, HOWEVER, that any commitment fee accrued with respect to any
of the Commitments of a Defaulting Lender during the period prior to the time
such Lender became a Defaulting Lender and unpaid at such time shall not be
payable by the Parent Borrower so long as such Lender shall be a Defaulting
Lender except to the extent that such commitment fee shall otherwise have been
due and payable by the Parent Borrower prior to such time; and PROVIDED FURTHER
that no commitment fee shall accrue on any of the Commitments of a Defaulting
Lender so long as such Lender shall be a Defaulting Lender.

                  (b) LETTER OF CREDIT FEES, ETC. (i) The Parent Borrower shall
pay to the Administrative Agent for the account of each Lender a commission,
payable in arrears quarterly on the last Business Day of each March, June,
September and December, commencing June 30, 1998, and on the earliest to occur
of the full drawing, expiration, termination or cancellation of any Letter of
Credit and on the Termination Date, on such Lender's Pro Rata Share of the
average daily aggregate Available Amount during such quarter of all Letters of
Credit outstanding from time to time at the Letter of Credit Fee Rate in effect
from time to time.

                  (ii) The Parent Borrower shall pay to the Issuing Bank, for
its own account, (A) a fronting fee for each Letter of Credit in an amount equal
to 0.25% of the Available Amount of such Letter of Credit on the date of
issuance of such Letter of Credit, payable on such date and (B) such
commissions, issuance fees, transfer fees and other fees and charges in
connection with the issuance or administration of each Letter of Credit as the
Parent Borrower and the Issuing Bank shall agree.

                                       37

                  (c) AGENTS' FEES.  The Parent Borrower shall pay to the 
Administrative Agent for its account the fees described in the Administrative
Agent's Fee Letter.

                  SECTION 2.09. CONVERSION OF ADVANCES. (a) OPTIONAL. Either
Borrower may on any Business Day, upon notice given to the Administrative Agent
not later than 11:00 A.M. (New York City time) on the third Business Day prior
to the date of the proposed Conversion and subject to the provisions of Sections
2.07 and 2.10, Convert all or any portion of the Advances of one Type comprising
the same Borrowing and owing by such Borrower into Advances of the other Type;
PROVIDED, HOWEVER, that any Conversion of Eurodollar Rate Advances into Base
Rate Advances shall be made only on the last day of an Interest Period for such
Eurodollar Rate Advances, any Conversion of Base Rate Advances into Eurodollar
Rate Advances shall be in an amount not less than the minimum amount specified
in Section 2.02(b), no Conversion of any Advances shall result in more separate
Borrowings than permitted under Section 2.02(b) and each Conversion of Advances
comprising part of the same Borrowing shall be made ratably among the Lenders in
accordance with their Working Capital Commitments. Each such notice of
Conversion shall, within the restrictions specified above, specify (i) the date
of such Conversion, (ii) the Advances to be Converted and (iii) if such
Conversion is into Eurodollar Rate Advances, the duration of the initial
Interest Period for such Advances. Each notice of Conversion shall be
irrevocable and binding on the Borrower giving such notice of Conversion.

                  (b) MANDATORY. (i) On the date on which the aggregate unpaid
principal amount of Eurodollar Rate Advances comprising any Borrowing shall be
reduced, by payment or prepayment or otherwise, to less than $3,000,000, such
Advances shall automatically Convert into Base Rate Advances.

                  (ii) If the applicable Borrower shall fail to select the
duration of any Interest Period for any Eurodollar Rate Advances in accordance
with the provisions contained in the definition of "Interest Period" in Section
1.01, the Administrative Agent shall forthwith so notify such Borrower and the
Lenders, whereupon each such Eurodollar Rate Advance will automatically, on the
last day of the then existing Interest Period therefor, Convert into a Base Rate
Advance.

                  (iii) Upon the occurrence and during the continuance of any
Event of Default, (x) each Eurodollar Rate Advance will automatically, on the
last day of the then existing Interest Period therefor, Convert into a Base Rate
Advance and (y) the obligation of the Lenders to make, or to Convert Advances
into, Eurodollar Rate Advances shall be suspended.

                  SECTION 2.10. INCREASED COSTS, ETC. (a) If, due to either (i)
the introduction of or any change in or in the interpretation of any law or
regulation or (ii) the compliance with any guideline or request from any central
bank or other governmental authority (whether or not having the force of law),
there shall be any increase in the cost to any Lender Party of agreeing to make
or of making, funding or maintaining Eurodollar Rate Advances or of agreeing to
issue or of issuing or maintaining Letters of Credit or of agreeing to make or
of making or maintaining Letter of Credit Advances (excluding, for purposes of
this Section 2.10, any such increased costs resulting from (x) Taxes or Other
Taxes (as to which Section 2.12 shall govern) and (y) changes in the basis of
taxation of overall net income or overall gross income by the United States or
by the foreign jurisdiction or state under the laws of which such Lender Party
is organized or has its Applicable Lending Office or any political subdivision
thereof), then each Borrower hereby jointly and severally agrees from time to
time, upon demand by such Lender Party (with a copy of such demand to the
Administrative Agent), to pay to the Administrative Agent for the account of
such



<PAGE>


                                       38

Lender Party additional amounts sufficient to compensate such Lender Party for
such increased cost. A certificate as to the amount of such increased cost,
submitted to the Borrowers by such Lender Party, shall
be conclusive and binding for all purposes, absent manifest error.

                  (b) If any Lender Party determines that compliance with any
law or regulation or any guideline or request from any central bank or other
governmental authority (whether or not having the force of law) affects or would
affect the amount of capital required or expected to be maintained by such
Lender Party or any corporation controlling such Lender Party and that the
amount of such capital is increased by or based upon the existence of such
Lender Party's commitment to lend or to issue Letters of Credit hereunder and
other commitments of such type or the issuance or maintenance of the Letters of
Credit (or similar contingent obligations), then each Borrower hereby jointly
and severally agrees, upon demand by such Lender Party (with a copy of such
demand to the Administrative Agent), to pay to the Administrative Agent for the
account of such Lender Party, from time to time as specified by such Lender
Party, additional amounts sufficient to compensate such Lender Party in the
light of such circumstances, to the extent that such Lender Party reasonably
determines such increase in capital to be allocable to the existence of such
Lender Party's commitment to lend or to issue Letters of Credit hereunder or to
the issuance or maintenance of any Letters of Credit. A certificate as to such
amounts submitted to the Borrowers by such Lender Party shall be conclusive and
binding for all purposes, absent manifest error. Each Lender Party shall use its
reasonable efforts to notify the Borrowers as to the existence of any change of
circumstance described in this Section 2.10(b) as promptly as practicable after
gaining knowledge thereof, but the failure to give notice required hereby shall
not affect the right of any Lender Party to any payment to which it would
otherwise be entitled hereunder.

                  (c) If, with respect to any Eurodollar Rate Advances, the
Required Lenders notify the Administrative Agent that the Eurodollar Rate for
any Interest Period for such Advances will not adequately reflect the cost to
such Lenders of making, funding or maintaining their Eurodollar Rate Advances
for such Interest Period, the Administrative Agent shall forthwith so notify the
Borrowers and the Lenders, whereupon (i) each such Eurodollar Rate Advance shall
automatically, on the last day of the then existing Interest Period therefor,
Convert into a Base Rate Advance and (ii) the obligation of the Lenders to make,
or to Convert Advances into, Eurodollar Rate Advances shall be suspended until
the Administrative Agent shall notify the Borrowers that such Lenders have
determined that the circumstances causing such suspension no longer exist.

                  (d) Notwithstanding any other provision of this Agreement, if
the introduction of or any change in or in the interpretation of any law or
regulation shall make it unlawful, or any central bank or other governmental
authority shall assert that it is unlawful, for any Lender or its Eurodollar
Lending Office to perform its obligations hereunder to make Eurodollar Rate
Advances or to continue to fund or maintain Eurodollar Rate Advances hereunder,
then, on notice thereof and demand therefor by such Lender to each Borrower
through the Administrative Agent, (i) each Eurodollar Rate Advance shall
automatically, upon such demand, Convert into a Base Rate Advance and (ii) the
obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate
Advances shall be suspended until the Administrative Agent shall notify the
Borrowers that such Lender has determined that the circumstances causing such
suspension no longer exist.

                  (e) Any Lender Party claiming any additional amounts payable
pursuant to clause (a), (b) or (c) of this Section 2.10 agrees to use its
reasonable efforts (consistent with its internal policy and



<PAGE>


                                       39

legal and regulatory restrictions) to designate a different Applicable Lending
Office if the making of such a designation would avoid the need for, or reduce
the amount of, such increased costs or additional amounts that may thereafter
accrue and would not, in the sole judgment of such Lender Party, be otherwise
disadvantageous to such Lender Party.

                  SECTION 2.11. PAYMENTS AND COMPUTATIONS. (a) Each Borrower
shall make each payment hereunder and under the Notes issued by such Borrower,
irrespective of any right of counterclaim or setoff (except as otherwise
provided in Section 2.15), not later than 11:00 A.M. (New York City time) on the
day when due in U.S. dollars to the Administrative Agent at the Administrative
Agent's Account in same day funds. The Administrative Agent shall promptly
thereafter cause like funds to be distributed (i) if such payment by either
Borrower is in respect of principal, interest, commitment fees or any other
Obligation then payable hereunder and under the Notes issued by such Borrower to
more than one Lender Party, to such Lender Parties for the account of their
respective Applicable Lending Offices ratably in accordance with the amounts of
such respective Obligations then payable to such Lender Parties and (ii) if such
payment by either Borrower is in respect of any Obligation then payable
hereunder to one Lender Party, to such Lender Party for the account of its
Applicable Lending Office, in each case to be applied in accordance with the
terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and
recording of the information contained therein in the Register pursuant to
Section 8.07(d), from and after the effective date of such Assignment and
Acceptance, the Administrative Agent shall make all payments hereunder and under
the Notes in respect of the interest assigned thereby to the Lender Party
assignee thereunder, and the parties to such Assignment and Acceptance shall
make all appropriate adjustments in such payments for periods prior to such
effective date directly between themselves.

                  (b) Each Borrower hereby authorizes each Lender Party, if and
to the extent payment owed to such Lender Party is not made when due hereunder
or, in the case of a Lender, under the Note issued by such Borrower and held by
such Lender, to charge from time to time against any or all of such
Borrower's accounts with such Lender Party any amount so due.

                  (c) The computation of interest on Base Rate Advances using an
interest rate determined pursuant to clause (a) of the definition of "Base Rate"
and the computation of the fees payable pursuant to Section 2.08(a) shall each
be made by the Administrative Agent on the basis of a year of 365 days or 366
days, as the case may be, in each case for the actual number of days (including
the first but excluding the last day) occurring in the period for which such
interest or commissions are payable. All other computations of interest, fees
and commissions shall be made by the Administrative Agent on the basis of a year
of 360 days, in each case for the actual number of days (including the first day
but excluding the last day) occurring in the period for which such interest,
fees or commissions are payable. Each determination by the Administrative Agent
of an interest rate, fee or commission hereunder shall be conclusive and binding
for all purposes, absent manifest error.

                  (d) Whenever any payment hereunder or under the Notes shall be
stated to be due on a day other than a Business Day, such payment shall be made
on the next succeeding Business Day, and such extension of time shall in such
case be included in the computation of payment of interest or commitment fee, as
the case may be; PROVIDED, HOWEVER, that, if such extension would cause payment
of interest on or principal of Eurodollar Rate Advances to be made in the next
following calendar month, such payment shall be made on the next preceding
Business Day.

                                       40

                  (e) Unless the Administrative Agent shall have received notice
from the applicable Borrower prior to the date on which any payment is due to
any Lender Party hereunder that such Borrower will not make such payment in
full, the Administrative Agent may assume that such Borrower has made such
payment in full to the Administrative Agent on such date and the Administrative
Agent may, in reliance upon such assumption, cause to be distributed to each
such Lender Party on such due date an amount equal to the amount then due such
Lender Party. If and to the extent such Borrower shall not have so made such
payment in full to the Administrative Agent, each such Lender Party shall repay
to the Administrative Agent forthwith on demand such amount distributed to such
Lender Party together with interest thereon, for each day from the date such
amount is distributed to such Lender Party until the date such Lender Party
repays such amount to the Administrative Agent, at the Federal Funds Rate.

                  SECTION 2.12. TAXES. (a) Any and all payments by either
Borrower hereunder or under the Notes issued by such Borrower shall be made, in
accordance with Section 2.11, free and clear of and without deduction for any
and all present or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, EXCLUDING, in the case
of each Lender Party and each Agent, taxes that are imposed on its net income by
the United States and taxes that are imposed on its net income (and franchise
taxes imposed in lieu thereof) by the state or foreign jurisdiction under the
laws of which such Lender Party or such Agent (as the case may be) is organized
or any political subdivision thereof and, in the case of each Lender Party,
taxes that are imposed on its overall net income (and franchise taxes imposed in
lieu thereof) by the state or foreign jurisdiction of such Lender Party's
Applicable Lending Office or any political subdivision thereof (all such
non-excluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities in respect of payments hereunder or under the Notes being
hereinafter referred to as "TAXES"). If either Borrower shall be required by law
to deduct any Taxes from or in respect of any sum payable hereunder or under any
Note issued by such Borrower to any Lender Party or any Agent, (i) the sum
payable by such Borrower shall be increased as may be necessary so that after
such Borrower and the Administrative Agent have made all required deductions
(including deductions applicable to additional sums payable under this Section
2.12) such Lender Party or such Agent (as the case may be) receives an amount
equal to the sum it would have received had no such deductions been made, (ii)
such Borrower shall make all such deductions and (iii) such Borrower shall pay
the full amount deducted to the relevant taxation authority or other authority
in accordance with applicable law.

                  (b) In addition, each Borrower shall pay any present or future
stamp, documentary, excise, property or similar taxes, charges or levies that
arise from any payment made hereunder or under the Notes issued by such Borrower
or from the execution, delivery or registration of, performance under, or
otherwise with respect to, this Agreement or the Notes issued by such Borrower
(hereinafter referred to as "OTHER TAXES").

                  (c) The Borrowers shall jointly and severally indemnify each
Lender Party and each Agent for and hold them harmless against the full amount
of Taxes and Other Taxes, and for the full amount of taxes of any kind imposed
by any jurisdiction on amounts payable under this Section 2.12, imposed on or
paid by such Lender Party or such Agent (as the case may be) and any liability
(including penalties, additions to tax, interest and expenses) arising therefrom
or with respect thereto. This indemnification shall be made within 30 days from
the date such Lender Party or such Agent (as the case may be) makes written
demand therefor.




<PAGE>


                                       41

                  (d) Within 30 days after the date of any payment of Taxes, the
applicable Borrower shall furnish to the Administrative Agent, at its address
referred to in Section 8.02, the original or a certified copy of a receipt
evidencing such payment.

                  (e) Each Lender Party organized under the laws of a
jurisdiction outside the United States shall, on or prior to the date of its
execution and delivery of this Agreement in the case of each Initial Lender or
Initial Issuing Bank, as the case may be, and on the date of the Assignment and
Acceptance pursuant to which it becomes a Lender Party in the case of each other
Lender Party, and from time to time thereafter as requested in writing by either
Borrower (but only so long thereafter as such Lender Party remains lawfully able
to do so), provide each of the Administrative Agent and such Borrower with two
original Internal Revenue Service forms 1001 or 4224 or (in the case of a Lender
that has certified in writing to the Administrative Agent and such Borrower that
it is not a "bank" as defined in Section 881(c)(3)(A) of the Internal Revenue
Code) form W-8 (and, if such Lender delivers a form W-8, a certificate
representing that such Lender is not a "bank" for purposes of Section 881(c) of
the Internal Revenue Code, is not a 10-percent shareholder (within the meaning
of Section 871(h)(3)(B) of the Internal Revenue Code) of such Borrower and is
not a controlled foreign corporation related to such Borrower (within the
meaning of Section 864(d)(4) of the Internal Revenue Code)), as appropriate, or
any successor or other form prescribed by the Internal Revenue Service,
certifying that such Lender Party is exempt from or entitled to a reduced rate
of United States withholding tax on payments pursuant to this Agreement or the
Notes issued by such Borrower or, in the case of a Lender providing a form W-8,
certifying that such Lender is a foreign corporation, partnership estate or
trust. If the forms provided by a Lender Party at the time such Lender Party
first becomes a party to this Agreement indicate a United States interest
withholding tax rate in excess of zero, withholding tax at such rate shall be
considered excluded from Taxes unless and until such Lender Party provides the
appropriate forms certifying that a lesser rate applies, whereupon withholding
tax at such lesser rate only shall be considered excluded from Taxes for periods
governed by such forms; PROVIDED, HOWEVER, that, if, at the date of the
Assignment and Acceptance pursuant to which a Lender Party becomes a party to
this Agreement, the Lender Party assignor was entitled to payments under
subsection (a) of this Section 2.12 in respect of United States withholding tax
with respect to interest paid at such date, then, to such extent, the term Taxes
shall include (in addition to withholding taxes that may be imposed in the
future or other amounts otherwise includable in Taxes) United States withholding
tax, if any, applicable with respect to the Lender Party assignee on such date.
For purposes of this subsection (e) and subsection (f) of this Section 2.12, the
terms "UNITED STATES" and "UNITED STATES PERSON" shall have the meanings
specified in Section 7701 of the Internal Revenue Code.

                  (f) For any period with respect to which a Lender Party has
failed to provide the applicable Borrower with the appropriate form described in
subsection (e) above (OTHER THAN if such failure is due to a change in law
enacted or promulgated after the date on which a form originally was required to
be provided or if such form otherwise is not required under subsection (e) of
this Section 2.12), such Lender Party shall not be entitled to indemnification
under subsection (a) or (c) of this Section 2.12 with respect to Taxes imposed
by the United States by reason of such failure; PROVIDED, HOWEVER, that should a
Lender Party become subject to Taxes because of its failure to deliver a form
required hereunder, such Borrower shall take such steps as such Lender Party
shall reasonably request to assist such Lender Party to recover such Taxes.

                  (g) In the event that a Lender Party determines in its
reasonable discretion, that it has actually and finally realized a refund of or
credit for taxes withheld or paid pursuant to this Section 2.12,



<PAGE>


                                       42

which credit or refund is identifiable by such Lender Party as being a result of
taxes withheld in connection with sums payable hereunder or under any other Loan
Document, such Lender Party shall promptly notify the Administrative Agent and
the Parent Borrower and shall remit to the Parent Borrower or the Sub Borrower,
as applicable, the amount of such refund or credit allocable to payments made
hereunder or under the other Loan Documents; PROVIDED, HOWEVER, that in the
event of any subsequent disallowance of any such refund or credit on account of
which such Lender Party has made a payment pursuant to this subsection (g), the
amount so disallowed shall be deemed to be a Tax (notwithstanding any exclusions
in the definition of "Taxes") for which such Lender Party shall be entitled to
indemnification under subsection (c) of this Section 2.12, but only to the
extent of any payment by such Lender Party pursuant to this subsection (g).

                  SECTION 2.13. SHARING OF PAYMENTS, ETC. If any Lender Party
shall obtain at any time any payment (whether voluntary, involuntary, through
the exercise of any right of setoff, or otherwise) (a) on account of Obligations
due and payable to such Lender Party hereunder and under the Notes at such time
in excess of its ratable share (according to the proportion of (i) the amount of
such Obligations due and payable to such Lender Party at such time to (ii) the
aggregate amount of the Obligations due and payable to all Lender Parties
hereunder and under the Notes at such time) of payments on account of the
Obligations due and payable to all Lender Parties hereunder and under the Notes
at such time obtained by all the Lender Parties at such time or (b) on account
of Obligations owing (but not due and payable) to such Lender Party hereunder
and under the Notes at such time in excess of its ratable share (according to
the proportion of (i) the amount of such Obligations owing to such Lender Party
at such time to (ii) the aggregate amount of the Obligations owing (but not due
and payable) to all Lender Parties hereunder and under the Notes at such time)
of payments on account of the Obligations owing (but not due and payable) to all
Lender Parties hereunder and under the Notes at such time obtained by all of the
Lender Parties at such time, such Lender Party shall forthwith purchase from the
other Lender Parties such participations in the Obligations due and payable or
owing to them, as the case may be, as shall be necessary to cause such
purchasing Lender Party to share the excess payment ratably with each of them;
PROVIDED, HOWEVER, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Lender Party, such purchase from each
other Lender Party shall be rescinded and such other Lender Party shall repay to
the purchasing Lender Party the purchase price to the extent of such Lender
Party's ratable share (according to the proportion of (i) the purchase price
paid to such Lender Party to (ii) the aggregate purchase price paid to all
Lender Parties) of such recovery together with an amount equal to such Lender
Party's ratable share (according to the proportion of (i) the amount of such
other Lender Party's required repayment to (ii) the total amount so recovered
from the purchasing Lender Party) of any interest or other amount paid or
payable by the purchasing Lender Party in respect of the total amount so
recovered. Each Borrower agrees that any Lender Party so purchasing a
participation from another Lender Party pursuant to this Section 2.13 may, to
the fullest extent permitted by law, exercise all its rights of payment
(including the right of setoff) with respect to such participation as fully as
if such Lender Party were the direct creditor of such Borrower in the amount of
such participation.

                  SECTION 2.14. USE OF PROCEEDS. The proceeds of the Advances
and issuances of Letters of Credit to the Parent Borrower shall be available
(and the Parent Borrower agrees that it shall use such proceeds and Letters of
Credit) solely to finance ongoing working capital requirements and for other
general corporate purposes, including, without limitation, Non-hostile
Acquisitions, of the Parent Borrower and its Subsidiaries. The proceeds of the
Advances to the Sub Borrower shall be available (and the Sub Borrower agrees
that it shall use such proceeds) solely to be lent to the Specified Subsidiaries
and to be used

                                       43

by the Specified Subsidiaries solely to finance ongoing working capital
requirements and for other general corporate purposes of the Specified
Subsidiaries.

                  SECTION 2.15. DEFAULTING LENDERS. (a) In the event that, at
any one time, (i) any Lender Party shall be a Defaulting Lender, (ii) such
Defaulting Lender shall owe a Defaulted Advance to either Borrower and (iii)
such Borrower shall be required to make any payment hereunder or under any other
Loan Document to or for the account of such Defaulting Lender, then such
Borrower may, so long as no Default shall occur or be continuing at such time
and to the fullest extent permitted by applicable law, set off and otherwise
apply the Obligation of such Borrower to make such payment to or for the account
of such Defaulting Lender against the obligation of such Defaulting Lender to
make such Defaulted Advance. In the event that, on any date, such Borrower shall
so set off and otherwise apply its Obligation to make any such payment against
the obligation of such Defaulting Lender to make any such Defaulted Advance on
or prior to such date, the amount so set off and otherwise applied by such
Borrower shall constitute for all purposes of this Agreement and the other Loan
Documents an Advance by such Defaulting Lender made on the date under the
Facility pursuant to which such Defaulted Advance was originally required to
have been made pursuant to Section 2.01. Such Advance shall be a Base Rate
Advance and shall be considered, for all purposes of this Agreement, to comprise
part of the Borrowing in connection with which such Defaulted Advance was
originally required to have been made pursuant to Section 2.01, even if the
other Advances comprising such Borrowing shall be Eurodollar Rate Advances on
the date such Advance is deemed to be made pursuant to this subsection (a). Each
Borrower shall notify the Administrative Agent at any time such Borrower
exercises its right of setoff pursuant to this subsection (a) and shall set
forth in such notice (A) the name of the Defaulting Lender and the Defaulted
Advance required to be made by such Defaulting Lender and (B) the amount set off
and otherwise applied in respect of such Defaulted Advance pursuant to this
subsection (a). Any portion of such payment otherwise required to be made by
such Borrower to or for the account of such Defaulting Lender that is paid by
such Borrower, after giving effect to the amount set off and otherwise applied
by such Borrower pursuant to this subsection (a), shall be applied by the
Administrative Agent as specified in subsection (b) or (c) of this Section 2.15.

                  (b) In the event that, at any one time, (i) any Lender Party
shall be a Defaulting Lender, (ii) such Defaulting Lender shall owe a Defaulted
Amount to any Agent or any of the other Lender Parties and (iii) either Borrower
shall make any payment hereunder or under any other Loan Document to the
Administrative Agent for the account of such Defaulting Lender, then the
Administrative Agent may, on its behalf or on behalf of such other Agents or
such other Lender Parties and to the fullest extent permitted by applicable law,
apply at such time the amount so paid by such Borrower to or for the account of
such Defaulting Lender to the payment of each such Defaulted Amount to the
extent required to pay such Defaulted Amount. In the event that the
Administrative Agent shall so apply any such amount to the payment of any such
Defaulted Amount on any date, the amount so applied by the Administrative Agent
shall constitute for all purposes of this Agreement and the other Loan Documents
payment, to such extent, of such Defaulted Amount on such date. Any such amount
so applied by the Administrative Agent shall be retained by the Administrative
Agent or distributed by the Administrative Agent to such other Agents or such
other Lender Parties, ratably in accordance with the respective portions of such
Defaulted Amounts payable at such time to the Administrative Agent, such other
Agents and such other Lender Parties and, if the amount of such payment made by
such Borrower shall at such time be insufficient to pay all Defaulted Amounts
owing at such time to the Administrative Agent, the other Agents and the other
Lender Parties, in the following order of priority:



<PAGE>


                                       44

                  (i) FIRST, to the Administrative Agent for any Defaulted
         Amount then owing to the Administrative Agent;

                  (ii) SECOND, to any other Agents for any Defaulted Amounts
         then owing to such other Agents, ratably in accordance with such
         respective Defaulted Amounts then owing to such other Agents; and

                  (iii) THIRD, to any other Lender Parties for any Defaulted
         Amounts then owing to such other Lender Parties, ratably in accordance
         with such respective Defaulted Amounts then owing
         to such other Lender Parties.

Any portion of such amount paid by such Borrower for the account of such
Defaulting Lender remaining, after giving effect to the amount applied by the
Administrative Agent pursuant to this subsection (b), shall be applied by the
Administrative Agent as specified in subsection (c) of this Section 2.15.

                  (c) In the event that, at any one time, (i) any Lender Party
shall be a Defaulting Lender, (ii) such Defaulting Lender shall not owe a
Defaulted Advance or a Defaulted Amount and (iii) either Borrower, any Agent or
any other Lender Party shall be required to pay or distribute any amount
hereunder or under any other Loan Document to or for the account of such
Defaulting Lender, then such Borrower, such Agent or such other Lender Party
shall pay such amount to the Administrative Agent to be held by the
Administrative Agent, to the fullest extent permitted by applicable law, in
escrow or the Administrative Agent shall, to the fullest extent permitted by
applicable law, hold in escrow such amount otherwise held by it. Any funds held
by the Administrative Agent in escrow under this subsection (c) shall be
deposited by the Administrative Agent in an account with IBJ Schroder Bank &
Trust Company, in the name and under the control of the Administrative Agent,
but subject to the provisions of this subsection (c). The terms applicable to
such account, including the rate of interest payable with respect to the credit
balance of such account from time to time, shall be IBJ Schroder Bank & Trust
Company's standard terms applicable to escrow accounts maintained with it. Any
interest credited to such account from time to time shall be held by the
Administrative Agent in escrow under, and applied by the Administrative Agent
from time to time in accordance with the provisions of, this subsection (c). The
Administrative Agent shall, to the fullest extent permitted by applicable law,
apply all funds so held in escrow from time to time to the extent necessary to
make any Advances required to be made by such Defaulting Lender and to pay any
amount payable by such Defaulting Lender hereunder and under the other Loan
Documents to the Administrative Agent, any other Agents or any other Lender
Party, as and when such Advances or amounts are required to be made or paid and,
if the amount so held in escrow shall at any time be insufficient to make and
pay all such Advances and amounts required to be made or paid at such time, in
the following order of priority:

                  (i) FIRST, to the Administrative Agent for any amount then due
         and payable by such Defaulting Lender to the Administrative Agent
         hereunder;

                  (ii) SECOND, to any other Agents for any amount then due and
         payable by such Defaulting Lender to such other Agents hereunder,
         ratably in accordance with such respective amounts then due and payable
         to such other Agents;




<PAGE>


                                       45

                  (iii) THIRD, to any other Lender Parties for any amount then
         due and payable by such Defaulting Lender to such other Lender Parties
         hereunder, ratably in accordance with such respective amounts then due
         and payable to such other Lender Parties; and

                  (iv) FOURTH, to the applicable Borrower for any Advance then
         required to be made to such Borrower by such Defaulting Lender pursuant
         to a Commitment of such Defaulting Lender.

In the event that any Lender Party that is a Defaulting Lender shall, at any
time, cease to be a Defaulting Lender, any funds held by the Administrative
Agent in escrow at such time with respect to such Lender Party shall be
distributed by the Administrative Agent to such Lender Party and applied by such
Lender Party to the Obligations owing to such Lender Party at such time under
this Agreement and the other Loan Documents ratably in accordance with the
respective amounts of such Obligations outstanding at such time.

                  (d) The rights and remedies against a Defaulting Lender under
this Section 2.15 are in addition to other rights and remedies that the
Borrowers may have against such Defaulting Lender with respect to any Defaulted
Advance and that the Administrative Agent, any Agent or any Lender Party may
have against such Defaulting Lender with respect to any Defaulted Amount.

         desirable in the conduct of the business of the Parent Borrower or such
         Subsidiary, as the case may be, and that the loss thereof is not
         disadvantageous in any material respect to the Parent Borrower, such
         Subsidiary or the Lender Parties.

         accountants; without limitation of the foregoing, the Collateral Agent
         may conduct audits of the Collateral up to two times in each Fiscal
         Year (unless an Event of Default shall have occurred and be continuing,
         in which case the right of the Collateral Agent to perform audits of
         the Collateral shall not be so limited), including, without limitation,
         inspection, reviews, evaluation and performance of counts of the
         Receivables, Inventory and other Collateral, PROVIDED that so long as
         no Event of Default shall have occurred and be continuing, the
         Collateral Agent shall coordinate its audits to coincide with the
         Parent Borrower's regularly scheduled internal cycle counts, PROVIDED
         FURTHER that in connection with any audit by the Collateral Agent, the
         Parent Borrower shall reimburse each auditor of the Collateral Agent at
         a rate of $650 per day plus actual out-of-pocket expenses (including,
         without limitation, travel expenses), PROVIDED STILL FURTHER that the
         Parent Borrower shall, at the request of the Collateral Agent, arrange

         and be continuing, permit the Collateral Agent to perform test
         verifications of the Collateral at such times as the Collateral Agent
         may request but in any event, so long as no Event of Default shall have
         occurred and be continuing, not more than two times in any Fiscal Year.

                  (g) PREPARATION OF ENVIRONMENTAL REPORTS. At the request of

         during the continuance of a Default, (ii) in the case of the Parent
         Borrower's or any of its Subsidiaries' acquisition of real property
         that could be reasonably likely to result in a Material Adverse Effect,
         and (iii) at any time when any Lender believes after reasonable inquiry
         that a condition or event exists or has occurred on any real property
         owned or operated by the Parent Borrower or any of its Subsidiaries
         that could be reasonably likely to result in a Material Adverse Effect,
         provide, or cause such Subsidiary to

                                       62

         provide, to the Agents and the Lender Parties within 60 days after such
         request, at the expense of the Parent Borrower or such Subsidiary, an
         environmental site assessment report for any of its or its
         Subsidiaries' properties described in such request, prepared by an
         environmental consulting firm acceptable to the Required Lenders,
         indicating the presence or absence of Hazardous Materials and the
         estimated cost of any compliance, removal or remedial action in
         connection with any Hazardous Materials on such properties; without
         limiting the generality of the foregoing, if the Required Lenders
         determine at any time that a material risk exists that any such report
         will not be provided within the time referred to above and the Required
         Lenders will be materially prejudiced by any such delay, the Required
         Lenders may retain an environmental consulting firm to prepare such
         report at the expense of the Parent Borrower, and the Parent Borrower
         hereby grants and agrees to cause any Subsidiary that owns any property
         described in such request to grant to the Agents, the Lender Parties,
         such firm and any agents or representatives thereof, subject to the
         rights of tenants, access to enter onto their respective properties to
         undertake such an assessment; PROVIDED, HOWEVER, that no such Persons
         shall unreasonably interfere with the operations conducted at such
         property and the Parent Borrower shall be given at least 2 Business
         Days' notice prior to such undertaking.

                  (h) KEEPING OF BOOKS. Keep, and cause each of its Subsidiaries

         leases to lapse or be terminated or any rights to renew such leases to
         be forfeited or canceled, notify the Administrative Agent of any
         default by any party with respect to such leases and cooperate with the
         Administrative Agent in all respects to cure any such default, and
         cause each of its Subsidiaries to do so, except, in any case, where the
         failure to do so, either individually or in the aggregate, could not be
         reasonably expected to have a Material Adverse Effect.

                  (k) PERFORMANCE OF RELATED DOCUMENTS. Perform and observe all

         observed by it, maintain each such Related Document in full force and

         take all such action to such end as may be from time to time requested
         by the Administrative Agent and, upon request of the Administrative
         Agent, make to each other party to each such Related Document such
         demands and requests for information and reports or for action as any
         Loan Party is entitled to make under such Related Document, except, in

         case, where the failure to do so, either individually or in the
         aggregate, could not be reasonably expected to have a Material Adverse
         Effect.

                  (m) TRANSACTIONS WITH AFFILIATES. Conduct, and cause each of
         its Subsidiaries to conduct, all transactions otherwise permitted under
         the Loan Documents with any of their Affiliates on terms that are fair

                  Agent to vest in the Administrative Agent (or in any
                  representative of the Administrative Agent designated by it)

         substantial part of its property and, in the case of any such
         proceeding instituted against it (but not instituted by it) that is
         being diligently contested by it in good faith, either such proceeding
         shall remain undismissed or unstayed for a period of 30 days or any of
         the actions sought in such proceeding (including, without limitation,
         the entry of an order for relief against, or the appointment of a
         receiver, trustee, custodian or other similar official for, it or any
         substantial part of its property) shall occur; or any Loan Party or any

         any Material Adverse Change;

then, and in any such event, the Administrative Agent (i) shall at the request,
or may with the consent, of the Required Lenders, by notice to the Borrowers,
declare the obligation of each Lender to make Advances (other than Letter of
Credit Advances by the Issuing Bank or a Lender pursuant to Section 2.03(c)) and

consent, of the Required Lenders, by notice to the Borrowers, declare the Notes,
all interest thereon and all other amounts payable under this Agreement and the
other Loan Documents to be forthwith due and payable, whereupon the Notes, all
such interest and all such amounts shall become and be forthwith due and
payable, without presentment, demand, protest or further notice of any kind, all
of which are hereby expressly waived by each Borrower; PROVIDED, HOWEVER, that
in the event of an actual or deemed entry of an order for relief with respect to
any Loan Party or any of its Subsidiaries under the Federal Bankruptcy Code, (x)

such demand the Parent Borrower shall, pay to the Administrative Agent on behalf
of the Lender Parties in same day funds at the Administrative Agent's office
designated in such demand, for deposit in the L/C Cash Collateral Account, an
amount equal to the aggregate Available Amount of all Letters of Credit then
outstanding. If at any time the Administrative Agent determines that any funds
held in the L/C Cash Collateral Account are subject to any right or claim of any
Person other than the Administrative Agent and the Lender Parties or that the
total amount of such funds is less than the aggregate Available Amount of all
Letters of Credit, the Parent Borrower shall, forthwith upon demand by the
Administrative Agent, pay to the Administrative Agent, as additional funds to be
deposited and held in the L/C Cash Collateral Account, an amount equal to the
excess of (a) such aggregate Available Amount over (b) the total amount of
funds, if any, then held in the L/C Cash Collateral Account that the
Administrative Agent determines to be free and clear of any such right and
claim.

                                   THE AGENTS

                  SECTION 7.01. AUTHORIZATION AND ACTION. Each Lender Party (in
its capacities as a Lender, the Issuing Bank (if applicable) and a potential
Hedge Bank) hereby appoints and authorizes each Agent to take such action as
agents on its behalf and to exercise such powers and discretion under this
Agreement and the other Loan Documents as are delegated to such Agent by the
terms hereof and thereof, together with such powers and discretion as are
reasonably incidental thereto. As to any matters not expressly provided for by
the Loan Documents (including, without limitation, enforcement or collection of
the Notes), no Agent shall be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions of
the Required Lenders, and such instructions shall be binding upon all Lender
Parties and all holders of Notes; PROVIDED, HOWEVER, that no Agent shall be
required to take any action that exposes such Agent to personal liability or
that is contrary to this Agreement or applicable law. The Administrative Agent
agrees to give to each Lender Party prompt notice of each notice given to it by
either Borrower pursuant to the terms of this Agreement.

                  SECTION 7.02. AGENTS' RELIANCE, ETC. Neither any Agent nor any
of their respective directors, officers, agents or employees shall be liable for
any action taken or omitted to be taken by it or them under or in connection
with the Loan Documents, except for its or their own gross negligence or willful
misconduct. Without limiting the generality of the foregoing, each Agent: (a)
may treat the payee of any Note as the holder thereof until, in the case of the
Administrative Agent, the Administrative Agent receives and accepts an
Assignment and Acceptance entered into by the Lender that is the payee of such
Note, as assignor, and an Eligible Assignee, as assignee, or, in the case of the
Syndication Agent and the Documentation Agent, such Agent has received notice
from the Administrative Agent that it has received and accepted such Assignment
and Acceptance, in each case as provided in Section 8.07; (b) may consult with
legal counsel (including counsel for any Loan Party), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken in good faith by it in accordance with the
advice of such counsel, accountants or experts; (c) make no warranty or
representation to any Lender Party and shall not be responsible to any Lender
Party for any statements, warranties or representations (whether written or
oral) made in or in connection with the Loan Documents; (d) shall not have any
duty to ascertain or to inquire as to the performance or observance of any of
the terms, covenants or conditions of any Loan Document on the part of any Loan
Party or to inspect the property (including the books and records) of any Loan
Party; (e) shall not be responsible to any Lender Party for the due execution,
legality, validity, enforceability, genuineness, sufficiency or value of, or the
perfection or priority of any Lien or security interest created or purported to
be created under or in connection with, any Loan Document or any other
instrument or document furnished pursuant thereto; and (f) shall incur no
liability under or in respect of any Loan Document by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telegram,
telecopy or telex) believed by it to be genuine and signed or sent by the proper
party or parties.

                  SECTION 7.03.  GOLDMAN SACHS, GE CAPITAL, MSSF AND AFFILIATES.
With respect to its Commitments, the Advances made by it and the Notes issued to
it, Goldman Sachs, GE Capital and MSSF shall have the same rights and powers
under the Loan Documents as any other Lender Party and may exercise the same as
though it were not the Documentation Agent, the Collateral Agent, the
Administrative

Agent or the Syndication Agent, as the case may be; and the term "Lender Party"
or "Lender Parties" shall, unless otherwise expressly indicated, include Goldman
Sachs, GE Capital and MSSF in their respective individual capacities. Goldman
Sachs, GE Capital and MSSF and their respective Affiliates may accept deposits
from, lend money to, act as trustee under indentures of, accept investment
banking engagements from and generally engage in any kind of business with, any
Loan Party, any of its Subsidiaries and any Person who may do business with or
own securities of any Loan Party or any such Subsidiary, all as if Goldman
Sachs, GE Capital and MSSF were not the Documentation Agent, the Collateral
Agent, the Administrative Agent or the Syndication Agent, as the case may be,
and without any duty to account therefor to the Lender Parties.

                  SECTION 7.04. LENDER PARTY CREDIT DECISION. Each Lender Party
acknowledges that it has, independently and without reliance upon any of the
Agents or any of the other Lender Parties and based on the financial statements
referred to in Section 4.01 and such other documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Lender Party also acknowledges that it will, independently and
without reliance upon any of the Agents or any of the other Lender Parties 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.

                  SECTION 7.05. INDEMNIFICATION. (a) Each Lender Party severally
agrees to indemnify each Agent (to the extent not promptly reimbursed by the
Borrowers) from and against such Lender Party's ratable share (determined as
provided below) of any and all liabilities, 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 such Agent in any way relating to or arising out of the Loan Documents
or any action taken or omitted by such Agent under the Loan Documents; PROVIDED,
HOWEVER, that no Lender Party shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from such Agent's gross negligence or
willful misconduct. Without limiting the foregoing, each Lender Party agrees to
reimburse each Agent promptly upon demand for its ratable share of any costs and
expenses (including, without limitation, fees and expenses of counsel) payable
by either Borrower under Section 8.04, to the extent that such Agent is not
promptly reimbursed for such costs and expenses by such Borrower. For purposes
of this subsection (a), the Lender Parties' respective ratable shares of any
amount shall be determined, at any time, according to the sum of (x) the
aggregate principal amount of the Advances outstanding at such time and owing to
the respective Lender Parties, (y) their respective Pro Rata Shares of the
aggregate Available Amount of all Letters of Credit outstanding at such time and
(z) their respective Unused Working Capital Commitments at such time; PROVIDED
that the aggregate principal amount of Letter of Credit Advances owing to the
Issuing Bank shall be considered to be owed to the Lenders ratably in accordance
with their respective Working Capital Commitments. In the event that any
Defaulted Advance shall be owing by any Defaulting Lender at any time, such
Lender Party's Commitment with respect to the Facility under which such
Defaulted Advance was required to have been made shall be considered to be
unused for purposes of this subsection (a) to the extent of the amount of such
Defaulted Advance. The failure of any Lender Party to reimburse an Agent
promptly upon demand for its ratable share of any amount required to be paid by
the Lender Party to such Agent as provided herein shall not relieve any other
Lender Party of its obligation hereunder to reimburse such Agent for its ratable
share of such amount, but no Lender Party shall be responsible for the failure
of any other Lender Party to reimburse such Agent for such other Lender Party's
ratable share of such amount.

                                       87

                  (b) Each Lender Party severally agrees to indemnify the
Issuing Bank (to the extent not promptly reimbursed by the Borrowers) from and
against such Lender Party's ratable share (determined as provided below) of any
and all liabilities, 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 the Issuing
Bank in any way relating to or arising out of the Loan Documents or any action
taken or omitted by the Issuing Bank under the Loan Documents; PROVIDED,
HOWEVER, that no Lender Party shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the Issuing Bank's gross
negligence or willful misconduct. Without limiting the foregoing, each Lender
Party agrees to reimburse the Issuing Bank promptly upon demand for its ratable
share of any costs and expenses (including, without limitation, fees and
expenses of counsel) payable by either Borrower under Section 8.04, to the
extent that the Issuing Bank is not promptly reimbursed for such costs and
expenses by such Borrower. For purposes of this subsection (b), the Lender
Parties' respective ratable shares of any amount shall be determined, at any
time, according to the sum of (a) the aggregate principal amount of the Advances
outstanding at such time and owing to the respective Lender Parties, (b) their
respective Pro Rata Shares of the aggregate Available Amount of all Letters of
Credit outstanding at such time and (c) their respective Unused Working Capital
Commitments at such time; PROVIDED that the aggregate principal amount of Letter
of Credit Advances owing to the Issuing Bank shall be considered to be owed to
the Lenders ratably in accordance with their respective Working Capital
Commitments. In the event that any Defaulted Advance shall be owing by any
Defaulting Lender at any time, such Lender Party's Commitment with respect to
the Facility under which such Defaulted Advance was required to have been made
shall be considered to be unused for purposes of this subsection (b) to the
extent of the amount of such Defaulted Advance. The failure of any Lender Party
to reimburse the Issuing Bank promptly upon demand for its ratable share of any
amount required to be paid by the Lender Parties to the Issuing Bank as provided
herein shall not relieve any other Lender Party of its obligation hereunder to
reimburse the Issuing Bank for its ratable share of such amount, but no Lender
Party shall be responsible for the failure of any other Lender Party to
reimburse the Issuing Bank for such other Lender Party's ratable share of such
amount.

                  (c) Without prejudice to the survival of any other agreement
of any Lender Party hereunder, the agreement and obligations of each Lender
Party contained in this Section 7.05 shall survive the payment in full of
principal, interest and all other amounts payable hereunder and under the other
Loan Documents.

                  SECTION 7.06. SUCCESSOR AGENTS. Any Agent may resign at any
time and, if at any time the Administrative Agent shall cease to be a Lender,
the Administrative Agent shall promptly thereafter resign by giving written
notice thereof to the Lender Parties and the Borrowers and may be removed at any
time with or without cause by the Required Lenders. Upon any such resignation or
removal, the Required Lenders shall have the right to appoint a successor Agent,
subject, so long as no Default shall have occurred and be continuing, to the
consent of the Parent Borrower, such consent not to be unreasonably withheld or
delayed, PROVIDED, HOWEVER, that, notwithstanding the foregoing, MSSF shall have
the right to resign as Administrative Agent and appoint a successor
Administrative Agent without the consent of the Lenders but subject, so long as
no Default shall have occurred and be continuing, to the consent of the Parent
Borrower, such consent not be unreasonably withheld. If no successor Agent shall
have been so appointed by the Required Lenders, and shall have accepted such
appointment, within 30 days after the retiring Agent's giving of notice of
resignation or the Required Lenders' removal of the retiring Agent, then the
retiring Agent may, on behalf of the Lender Parties, appoint a successor Agent,
which shall be,



<PAGE>


                                       88

in the case of the Administrative Agent, a Lender that is a financial
institution organized under the laws of the United States or of any State
thereof. Upon the acceptance of any appointment as Agent hereunder by a
successor Agent and upon the execution and filing or recording of such financing
statements, or amendments thereto and such other instruments or notices, as may
be necessary or desirable, or as the Required Lenders may request, in order to
continue the perfection of the Liens granted or purported to be granted by the
Collateral Documents, such successor Agent shall succeed to and become vested
with all the rights, powers, discretion, privileges and duties of the retiring
Agent, and the retiring Agent shall be discharged from its duties and
obligations under the Loan Documents. After any retiring Agent's resignation or
removal hereunder as an Agent, the provisions of this Article VII shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was an
Agent under this Agreement.


                                  ARTICLE VIII

waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given; PROVIDED, HOWEVER, that no amendment, waiver

                  (b) Each Borrower agrees jointly and severally to indemnify
and hold harmless each Agent, each Lender Party and each of their respective
Affiliates and their respective officers, directors, employees, agents and
advisors (each, an "INDEMNIFIED PARTY") from and against any and all claims,
damages, losses, liabilities and expenses (including, without limitation,
reasonable fees and expenses of counsel) that may be incurred by or asserted or
awarded against any Indemnified Party, in each case arising out of or in
connection with or by reason of (including, without limitation, in connection
with any investigation, litigation or proceeding or preparation of a defense in
connection therewith) (i) the Facilities, the actual or proposed use of the
proceeds of the Advances or the Letters of Credit, the Loan Documents or any of
the transactions contemplated thereby, including, without limitation, any
acquisition or proposed acquisition (including, without limitation, the
Transaction) by the Equity Investors or any of their respective Subsidiaries or
Affiliates of all or any portion of the stock or substantially all the assets of
the Parent Borrower or any of its Subsidiaries or by the Parent Borrower or any
of its Subsidiaries or Affiliates or (ii) the actual or alleged presence of
Hazardous Materials on any property of any Loan Party or any of its Subsidiaries
or any Environmental Action relating in any way to any Loan Party or any of its
Subsidiaries, except to the extent such claim, damage, loss, liability or
expense is found in a final, non-appealable judgment by a court of competent
jurisdiction to have resulted directly and primarily from such Indemnified
Party's bad faith, gross negligence or willful misconduct. In the case of an
investigation, litigation or other proceeding to which the indemnity in this
subsection (b) applies, such indemnity shall be effective whether or not such
investigation, litigation or proceeding is brought by any Loan Party, its
directors, shareholders or creditors or an Indemnified Party or any Indemnified
Party is otherwise a party thereto and whether or not the transactions
contemplated hereby are consummated. Each Borrower also agrees not to assert any
claim against any Agent, any Lender Party or any of their Affiliates, or any of
their respective officers, directors, employees, attorneys or agents, on any
theory of liability, for special, indirect, consequential or punitive damages
arising out of or otherwise relating to the Facilities, the actual or proposed
use of the proceeds of the Advances or the Letters of Credit, the Loan Documents
or any of the transactions contemplated thereby.

                  (c) If any payment of principal of, or Conversion of, any
Eurodollar Rate Advance is made by either Borrower to or for the account of a
Lender Party other than on the last day of the Interest Period for such Advance,
as a result of a payment or Conversion pursuant to Section 2.09(b)(i) or
2.10(d), acceleration of the maturity of the Notes pursuant to Section 6.01 or
for any other reason, or by an Eligible Assignee to a Lender Party other than on
the last day of the Interest Period for such Advance upon an assignment of
rights and obligations under this Agreement pursuant to Section 8.07 as a result
of a demand by the Parent Borrower pursuant to Section 8.07(a), such Borrower
shall, upon demand by such Lender Party (with a copy of such demand to the
Administrative Agent), pay to the Administrative Agent for the account of such
Lender Party any amounts required to compensate such Lender Party for any
additional losses, costs or expenses that it may reasonably incur as a result of
such payment, including, without limitation, any loss (including loss of
anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by any Lender Party to fund or
maintain such Advance.

                  (d) If any Loan Party fails to pay when due any costs,
expenses or other amounts payable by it under any Loan Document, including,
without limitation, fees and expenses of counsel and indemnities, such amount
may be paid on behalf of such Loan Party by the Administrative Agent or any
Lender Party, in its sole discretion.

Section 8.04 shall survive the payment in full of principal, interest and all
other amounts payable hereunder and under any of the other Loan Documents.

during the continuance of any Event of Default and (b) the making of the request
or the granting of the consent specified by Section 6.01 to authorize the
Administrative Agent to declare the Notes due and payable pursuant to the
provisions of Section 6.01, each Lender Party and each of its Affiliates is
hereby authorized at any time and from time to time, to the fullest extent
permitted by law, to set off and otherwise 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 Party or such Affiliate to or for
the credit or the account of either Borrower against any and all of the
Obligations of such Borrower now or hereafter existing under this Agreement and
the Note or Notes (if any) held by such Lender Party, irrespective of whether
such Lender Party shall have made any demand under this Agreement or such Note
or Notes and although such obligations may be unmatured. Each Lender Party
agrees promptly to notify the applicable Borrower after any such setoff and
application; PROVIDED, HOWEVER, that the failure to give such notice shall not
affect the validity of such setoff and application. The rights of each Lender
Party and its respective Affiliates under this Section 8.05 are in addition to
other rights and remedies (including, without limitation, other rights of
setoff) that such Lender Party and its Affiliates may have.

                  SECTION 8.06. BINDING EFFECT. This Agreement shall become
effective when it shall have been executed by each Borrower, the Administrative
Agent, the Documentation Agent and the Syndication Agent and when the
Administrative Agent shall have been notified by each Initial Lender and the
Initial Issuing Bank that such Initial Lender and the Initial Issuing Bank has
executed it and thereafter shall be binding upon and inure to the benefit of
each Borrower, each Agent and each Lender Party and their respective successors
and assigns, except that neither Borrower shall have the right to assign its
rights hereunder or any interest herein without the prior written consent of the
Lender Parties.

Section 2.10) upon at least five Business Days' notice to such Lender and the
Administrative Agent, will assign to one or more Eligible Assignees all or a
portion of its rights and obligations under this Agreement (including, without
limitation, all or a portion of its Commitment or Commitments, the Advances
owing to it and the Note or Notes held by it); PROVIDED, HOWEVER, that (i) each
such assignment shall be of a uniform, and not a varying, percentage of all
rights and obligations under and in respect of all of the Facilities, (ii)
except in the case of an assignment of all of a Lender's rights and obligations
under this Agreement, the amount of the Commitment of the assigning Lender being
assigned pursuant to each such assignment (determined as of the date of the
Assignment and Acceptance with respect to such assignment) shall in no event be
less than $5,000,000, (iii) each such assignment shall be to an Eligible
Assignee, (iv) each such assignment made as a result of a demand by the Parent
Borrower pursuant to this Section 8.07(a) shall be arranged by the Parent
Borrower after consultation with the Administrative Agent and shall be either an
assignment of all of the rights and obligations of the assigning Lender under
this Agreement or an assignment of a portion of such rights and obligations made
concurrently with another such assignment or other such assignments that
together cover all of the rights and obligations of the assigning Lender under
this Agreement, (v) no Lender shall be obligated to make any such assignment as

                                       92

a result of a demand by the Parent Borrower pursuant to this Section 8.07(a)
unless and until such Lender shall have received one or more payments from
either the Parent Borrower or one or more Eligible Assignees in an aggregate
amount at least equal to the aggregate outstanding principal amount of the
Advances owing to such Lender, together with accrued interest thereon to the
date of payment of such principal amount and all other amounts payable to such
Lender under this Agreement, (vi) no such assignments shall be permitted without
the consent of the Syndication Agent until the Syndication Agent shall have
notified the Lender Parties that syndication of the Commitments hereunder has
been completed, and (vii) the parties to each such assignment shall execute and
deliver to the Administrative Agent, for its acceptance and recording in the
Register, an Assignment and Acceptance, together with any Note or Notes subject
to such assignment and a processing and recordation fee of (A) $1,500 if such
assignment is to an existing Lender Party, (B) $0 if such assignment is to an
Affiliate of the assigning Lender Party and (C) $3,000 in all other cases.

                  (b) Upon such execution, delivery, acceptance and recording,
from and after the effective date specified in such Assignment and Acceptance,
(x) the assignee thereunder shall be a party hereto and, to the extent that
rights and obligations hereunder have been assigned to it pursuant to such
Assignment and Acceptance, have the rights and obligations of a Lender or
Issuing Bank, as the case may be, hereunder and (y) the Lender or Issuing Bank
assignor thereunder shall, to the extent that rights and obligations hereunder
have been assigned by it pursuant to such Assignment and Acceptance, relinquish
its rights and be released from its obligations under this Agreement (and, in
the case of an Assignment and Acceptance covering all or the remaining portion
of an assigning Lender's or Issuing Bank's rights and obligations under this
Agreement, such Lender or Issuing Bank shall cease to be a party hereto).

                  (c) By executing and delivering an Assignment and Acceptance,
the Lender Party assignor thereunder and the assignee thereunder confirm to and
agree with each other and the other parties hereto as follows: (i) other than as
provided in such Assignment and Acceptance, such assigning Lender Party makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or any other Loan Document or the execution, legality, validity,
enforceability, genuineness, sufficiency or value of, or the perfection or
priority of any Lien or security interest created or purported to be created
under or in connection with, this Agreement or any other Loan Document or any
other instrument or document furnished pursuant hereto or thereto; (ii) such
assigning Lender Party makes no representation or warranty and assumes no
responsibility with respect to the financial condition of either Borrower or any
other Loan Party or the performance or observance by any Loan Party of any of
its obligations under any Loan Document or any other instrument or document
furnished pursuant thereto; (iii) such assignee confirms that it has received a
copy of this Agreement, together with copies of the financial statements
referred to in Section 4.01 and such other documents and information as it has
deemed appropriate to make its own credit analysis and decision to enter into
such Assignment and Acceptance; (iv) such assignee will, independently and
without reliance upon the Agents, such assigning Lender Party or any other
Lender Party 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; (v) such assignee confirms that it is an
Eligible Assignee; (vi) such assignee appoints and authorizes each Agent to take
such action as agents on its behalf and to exercise such powers and discretion
under the Loan Documents as are delegated to such Agent by the terms hereof,
together with such powers and discretion as are reasonably incidental thereto;
and (vii) such assignee agrees that it will perform in accordance with their
terms all of the obligations



<PAGE>


                                       93

which by the terms of this Agreement are required to be performed by it as a
Lender or Issuing Bank, as the case may be.

                  (d) The Administrative Agent, acting for this purpose (but
only for this purpose) as the agent of the Borrowers, shall maintain at its
address referred to in Section 8.02 a copy of each Assignment and Acceptance
delivered to and accepted by it and a register for the recordation of the names
and addresses of the Lender Parties and the Commitment of, and principal amount
of the Advances owing to, each Lender Party from time to time (the "REGISTER").
The entries in the Register shall be conclusive and binding for all purposes,
absent manifest error, and the Borrowers, the Agents and the Lender Parties
shall treat each Person whose name is recorded in the Register as a Lender Party
hereunder for all purposes of this Agreement. The Register shall be available
for inspection by either Borrower or any Lender Party at any reasonable time and
from time to time upon reasonable prior notice.

                  (e) Upon its receipt of an Assignment and Acceptance executed
by an assigning Lender Party and an assignee, together with any Note or Notes
subject to such assignment, the Administrative Agent shall, if such Assignment
and Acceptance has been completed and is in substantially the form of Exhibit C
hereto, (i) accept such Assignment and Acceptance, (ii) record the information
contained therein in the Register and (iii) give prompt notice thereof to the
Borrowers and the other Agents. In the case of any assignment by a Lender,
within five Business Days after its receipt of such notice, each Borrower, at
its own expense, shall execute and deliver to the Administrative Agent in
exchange for the surrendered Note or Notes a new Note to the order of such
Eligible Assignee in an amount equal to the Commitment assumed by it pursuant to
such Assignment and Acceptance and, if the assigning Lender has retained a
Commitment hereunder, a new Note to the order of the assigning Lender in an

                   (f) The Issuing Bank may assign to an Eligible Assignee all

PROVIDED, HOWEVER, that (i) each such assignment shall be to an Eligible
Assignee and (ii) the parties to each such assignment shall execute and deliver
to the Administrative Agent, for its acceptance and recording in the Register,
an Assignment and Acceptance, together with a processing and recordation fee of
(A) $1,500 if such assignment is to an existing Lender Party, (B) $0 if such
assignment is to an Affiliate of the assigning Lender Party and (C) $3,000 in
all other cases.

                  (g) Each Lender Party may sell participations to one or more
Persons (other than any Loan Party or any of its Affiliates) in or to all or a
portion of its rights and obligations under this Agreement (including, without
limitation, all or a portion of its Commitments, the Advances owing to it and
the Note or Notes (if any) held by it); PROVIDED, HOWEVER, that (i) such Lender
Party's obligations under this Agreement (including, without limitation, its
Commitments) shall remain unchanged, (ii) such Lender Party shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(iii) such Lender Party shall remain the holder of any such Note for all
purposes of this Agreement, (iv) the Borrowers, the Agents and the other Lender
Parties shall continue to deal solely and directly with such Lender Party in
connection with such Lender Party's rights and obligations under this Agreement
and (v) no participant under any such participation shall have any right to
approve any amendment or waiver of any provision of any Loan Document, or any
consent to any departure by any



<PAGE>


                                       94

Loan Party therefrom, except to the extent that such amendment, waiver or
consent would reduce the principal of, or interest on, the Notes or any fees or
other amounts payable hereunder, in each case to the extent subject to such
participation, postpone any date fixed for any payment of principal of, or
interest on, the Notes or any fees or other amounts payable hereunder, in each
case to the extent subject to such participation, or release all or
substantially all of the Collateral.

                  (h) Any Lender Party may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
8.07, disclose to the assignee or participant or proposed assignee or
participant, any information relating to either Borrower furnished to such
Lender Party by or on behalf of such Borrower; PROVIDED, HOWEVER, that, prior to
any such disclosure, the assignee or participant or proposed assignee or
participant shall agree to preserve in accordance with Section 8.10 the
confidentiality of any confidential information relating to any Loan Party
received by it from such Lender Party.

                  (i) Notwithstanding any other provision set forth in this
Agreement, any Lender Party may at any time create a security interest in all or
any portion of its rights under this Agreement (including, without limitation,
the Advances owing to it and the Note or Notes held by it) in favor of any
Federal Reserve Bank in accordance with Regulation A of the Board of Governors
of the Federal Reserve System.

                  SECTION 8.08. EXECUTION IN COUNTERPARTS. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement. Delivery of an executed counterpart of a signature page to this
Agreement by telecopier shall be effective as delivery of a manually executed
counterpart of this Agreement.

                  SECTION 8.09. NO LIABILITY OF THE ISSUING BANK. The Parent
Borrower assumes all risks of the acts or omissions of any beneficiary or
transferee of any Letter of Credit with respect to its use of such Letter of
Credit. Neither the Issuing Bank nor any of its officers or directors shall be
liable or responsible for: (a) the use that may be made of any Letter of Credit
or any acts or omissions of any beneficiary or transferee in connection
therewith; (b) the validity, sufficiency or genuineness of documents, or of any
endorsement thereon, even if such documents should prove to be in any or all
respects invalid, insufficient, fraudulent or forged; (c) payment by the Issuing
Bank against presentation of documents that do not comply with the terms of a
Letter of Credit, including failure of any documents to bear any reference or
adequate reference to the Letter of Credit; or (d) any other circumstances
whatsoever in making or failing to make payment under any Letter of Credit;
EXCEPT that the Parent Borrower shall have a claim against the Issuing Bank, and
the Issuing Bank shall be liable to the Parent Borrower, to the extent of any
direct, but not consequential, damages suffered by the Parent Borrower that the
Parent Borrower proves were caused by (i) the Issuing Bank's willful misconduct
or gross negligence in determining whether documents presented under any Letter
of Credit comply with the terms of the Letter of Credit or (ii) the Issuing
Bank's willful failure to make lawful payment under a Letter of Credit after the
presentation to it of a draft and certificates strictly complying with the terms
and conditions of the Letter of Credit. In furtherance and not in limitation of
the foregoing, 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.

or participant, in breach of any agreement or other obligation to either
Borrower, from a source other than such Borrower; (e) disclosure to the extent

may otherwise have to bring any action or proceeding relating to this Agreement

                  (b) Each of the parties hereto 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 any of the
other Loan Documents to which it is a party 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.

                  SECTION 8.13.  GOVERNING LAW.  This Agreement and the Notes

or the actions of any Agent or any Lender Party in the negotiation,
administration, performance or enforcement thereof.

                  IN WITNESS WHEREOF, the parties hereto have caused this

PRESS RELEASE


IPC Information Systems Closes Merger With Cable Systems
Holding - Intends To Effect 3 For 2 Stock Split

         NEW YORK, MAY 1, 1998 - IPC Information Systems, Inc. (formerly,
NASDAQ:IPCI, now IPCX), a leading provider of financial trading services
worldwide, today announced that it has closed its recapitalization merger with
Cable Systems Holding, LLC (CSH LLC).

         As previously announced, IPC stockholders had the option to receive $21
per share in cash, or to retain a portion of their equity, not to exceed 46
percent in total, in the recapitalized company. Richard P. Kleinknecht, who,
prior to the merger, served as Chairman of IPC, and after the merger, will serve
as Vice Chairman of IPC, retained 380,952 shares of common stock in the
surviving entity (equal to 10%). Other IPC stockholders elected to retain
822,828 shares of common stock in the surviving entity, which, together with the
shares retained by Richard P. Kleinknecht, represent approximately 32% of the
common stock in the surviving entity.

         IPC issued $247,400,000 aggregate principal amount at maturity
($180,010,714 initial proceeds upon issuance) of its 10-7/8% senior discount
notes, the proceeds of which, together with the $54,720,000 of capital provided
by CSH LLC, its indirect subsidiary Cable Systems International, Inc. and the
investment fund Lawrence Smith & Horey III, L.P., were used to repurchase shares
of IPC common stock from IPC stockholders who chose to receive cash in exchange
for their shares. Morgan Stanley & Co. Incorporated and Goldman, Sachs & Co.
arranged the debt financing. IPC also entered into a $55 million revolving
credit facility with Morgan Stanley Senior Funding, Inc., as syndication agent,
to be used by IPC for working capital and other purposes.

         Commencing today, May 1, 1998, IPC will be listed on the NASDAQ
SmallCap Market. IPC intends, with the approval of IPC's new controlling
stockholders, to effect a 3 for 2 stock split as soon as practicable.

         CSH LLC is headquartered in Phoenix, Arizona. CSH LLC has one direct
operating subsidiary, Cable Systems Holding Company (CSH), a manufacturer of
telecommunications products for outside plant, customer premises, broadband
networks, specialized cable assemblies and contract assembly services.

         IPC Information Systems, Inc. is a world leader in the delivery of
integrated multimedia communications solutions to the financial trading
industry. IPC serves customers in more than 35 countries. Its patented digital
TRADENET MX(R) turret is the most widely installed voice trading system in the
world. With its subsidiary, IXnet, IPC has created the first global virtual
private network, connecting trading companies with customers and counterparts
around the world. In addition, IPC installs and maintains communications cable
infrastructure, video and call logging systems, communication integration
services, and complete customer care programs.
