To the Holders of Common Stock of
Marsam Pharmaceuticals Inc.:

                                  INTRODUCTION

    Schein  Pharmaceutical,  Inc.,  a  Delaware  corporation  (the "Purchaser"),
hereby offers to purchase all the  outstanding shares of common stock, $.01  par
value  (the "Shares"),  of Marsam  Pharmaceuticals Inc.,  a Delaware corporation
(the "Company"), at a  purchase price of $21.00  per Share (the "Offer  Price"),
net  to the  seller in cash,  upon the terms  and subject to  the conditions set
forth in this Offer to Purchase and in the related Letter of Transmittal (which,
together  with  any  amendments  or  supplements,  collectively  constitute  the
"Offer").

    The  Offer is being made  pursuant to an agreement  and plan of merger dated
July 28, 1995 (the  "Merger Agreement") among the  Purchaser, SM Acquiring  Co.,
Inc., a Delaware corporation and a wholly-owned subsidiary of the Purchaser (the
"Sub"),  and the Company. The Merger Agreement provides, among other things, for
the commencement  of the  Offer  by the  Purchaser  and further  provides  that,
subject  to the satisfaction or waiver of certain conditions, the Purchaser will
transfer to the Sub all the Shares held  by it, and the Sub will be merged  with
and  into the Company (the "Merger"), with the Company surviving the Merger as a
direct, wholly-owned subsidiary of the Purchaser (the "Surviving  Corporation").
In the Merger, each outstanding Share (other than Shares owned by the Company or
any subsidiary of the Company, the Purchaser, the Sub or any other subsidiary of
the  Purchaser,  and  Shares  owned  by  stockholders  who  shall  have properly
exercised their appraisal rights  under Delaware law) will  be converted at  the
effective  time of the Merger  (the "Effective Time") into  the right to receive
the Offer Price  in cash,  without interest  and less  any required  withholding
taxes (the "Merger Consideration").

    The  board  of  directors  of  the  Company  (the  "Board")  has unanimously
determined that  each of  the Offer  and  Merger is  fair to,  and in  the  best
interests  of, the Company's stockholders (the "Stockholders"), has approved the
Merger Agreement  and the  transactions contemplated  by the  Merger  Agreement,
including  the Offer and Merger, and recommends that the Stockholders accept the
Offer and tender all their Shares pursuant to the Offer.

    Bear, Stearns & Co. Inc., the Company's financial advisor ("Bear  Stearns"),
has  delivered to the Company  its written opinion dated  the date of the Merger
Agreement that  the  consideration to  be  received  by holders  of  the  Shares
pursuant  to the Offer and  Merger is fair to  the Company's public Stockholders
from a  financial point  of view.  A  copy of  the opinion  of Bear  Stearns  is
contained  in the  Company's Solicitation/ Recommendation  Statement on Schedule
14D-9 (the "Schedule 14D-9") filed  with the Securities and Exchange  Commission
(the  "Commission")  in connection  with the  Offer,  a copy  of which  is being
furnished to Stockholders concurrently with this Offer to Purchase.

    The Offer  is conditioned  upon,  among other  things, there  being  validly
tendered  and not properly withdrawn prior to the Expiration Date (as defined in
Section 1 below)  that number of  Shares (the "Minimum  Number of Shares")  that
would  represent, on a fully diluted basis, a majority of the outstanding Shares
(the "Minimum Tender  Condition"). The Offer  also is subject  to certain  other
conditions. See Sections 1 and 14.

    The Company has informed the Purchaser that, as of July 26, 1995, there were
(i)  11,084,137  Shares  outstanding  and (ii)  outstanding  stock  options (the
"Marsam Options") granted by the Company  to purchase an aggregate of  1,166,649
Shares.

    Concurrently  with the execution of the  Merger Agreement, the Purchaser and
the Sub  entered  into  a  stockholders  agreement  dated  July  28,  1995  (the
"Stockholders Agreement") with certain Stockholders (the "Selling Stockholders")
owning,  in  the  aggregate,  3,071,132  Shares  (or  approximately  25%  of the
outstanding Shares  calculated  on  a  fully diluted  basis).  Pursuant  to  the
Stockholders  Agreement, the Selling Stockholders have agreed to tender pursuant
to the Offer and not withdraw an aggregate of 2,871,132 Shares (or approximately
24% of the  outstanding Shares  calculated on a  fully diluted  basis) that  are
owned  beneficially by them plus any Shares  issued to them upon the exercise of
Marsam Options (collectively, the "Founders Shares"). The tender of the Founders
Shares by the Selling Stockholders will not be sufficient to satisfy the Minimum
Tender Condition.
<PAGE>
Pursuant to the Stockholders Agreement, the  Purchaser has the right to  acquire
from the Selling Stockholders at the Offer Price all the Founders Shares, if (i)
the  Offer is terminated, abandoned or withdrawn by the Purchaser or the Sub due
to the failure of certain conditions to the Offer, (ii) the Merger Agreement  is
terminated  by the Purchaser  or the Company  by reason of  a court of competent
jurisdiction having issued, in connection with a suit, action or proceeding by a
party that  has made  an  Acquisition Proposal  (as  defined under  "The  Merger
Agreement  --  No  Solicitation"  below),  an  order  (other  than  a  temporary
restraining order),  a  decree  or  ruling or  having  taken  any  other  action
restraining,  enjoining or otherwise prohibiting the purchase of Shares pursuant
to the  Offer or  the Merger,  provided that  the party  terminating the  Merger
Agreement  used its reasonable best efforts to  remove or lift the order, decree
or ruling, or (iii) the Offer is consummated, but the Purchaser has not accepted
for payment  and  paid  for  the Founders  Shares  and  such  non-acceptance  or
non-payment  is not in contravention of the Purchaser's or the Sub's obligations
under the Merger Agreement or the Offer. Subject to certain conditions specified
in the Stockholders  Agreement, that right  is exercisable in  whole but not  in
part for the 30-day period following the first to occur of the foregoing events.

    The consummation of the Merger is subject to the satisfaction or waiver of a
number  of conditions, including, if required, the approval of the Merger by the
requisite vote  or  consent of  the  Stockholders. Under  the  Delaware  General
Corporation  Law (the  "DGCL"), the  stockholder vote  necessary to  approve the
Merger will be the affirmative  vote of at least  a majority of the  outstanding
Shares,  including Shares held by the Purchaser and its affiliates. Accordingly,
even if,  upon  the terms  and  subject to  the  conditions of  the  Offer,  the
Purchaser  purchases  all  the Shares  owned  by the  Selling  Stockholders, the
Purchaser will not  have the votes  required to approve  the Merger without  the
affirmative  vote of other Stockholders. If  the Purchaser acquires at least 90%
of the outstanding  Shares pursuant  to the  Offer or  otherwise, the  Purchaser
would  be  able  to  effect  the  Merger  pursuant  to  the  "short-form" merger
provisions of Section 253 of  the DGCL, without prior  notice to, or any  action
by,  any other Stockholder. In  that event, the Purchaser  intends to effect the
Merger as promptly as practicable following the purchase of Shares in the Offer.
See Section 12.

    The Merger Agreement and Stockholders Agreement are more fully described  in
Section  12.  Certain federal  income  tax consequences  of  the sale  of Shares
pursuant to the Offer  and the exchange of  Shares for the Merger  Consideration
pursuant to the Merger are described in Section 5.

    Tendering  Stockholders  will  not be  obligated  to pay  brokerage  fees or
commissions or,  except  as  set  forth  in  Instruction  6  to  the  Letter  of
Transmittal,  transfer taxes on the purchase of  Shares pursuant to the Offer or
Merger. The  Purchaser  will pay  all  charges  and expenses  of  Chemical  Bank
("Chemical"),  the depositary (the "Depositary"),  and Georgeson & Company Inc.,
as the  information agent  (the  "Information Agent"),  in connection  with  the
Offer. See Section 16.

1.  TERMS OF THE OFFER

    Upon the terms and subject to the conditions of the Offer (including, if the
Offer  is extended or amended, the terms and conditions of any such extension or
amendment), the Purchaser  will accept  for payment (and  thereby purchase)  all
Shares  that are validly tendered and not withdrawn in accordance with Section 4
below prior to the Expiration Date. As  used in the Offer, the term  "Expiration
Date"  means 12:00 midnight, New  York City time, on  Friday, September 1, 1995,
unless and until the Purchaser,  in accordance with the  terms of the Offer  and
the  Merger Agreement, shall have  extended the period of  time during which the
Offer is open, in which event the  term "Expiration Date" means the latest  time
and  date at which the Offer, as so  extended, expires. As used in this Offer to
Purchase, "business day" has the meaning set forth in Rule 14d-1(c)(6) under the
Securities Exchange Act of 1934 (the "Exchange Act").

    In the event that the  Offer is not consummated,  the Purchaser may seek  to
acquire  additional Shares  through open market  purchases, privately negotiated
transactions or otherwise, upon such terms and conditions and at such prices  as
it  shall determine, which may be more or less than the Offer Price and could be
for cash or other consideration.

                                       2
<PAGE>
    The Offer  is conditioned  upon,  among other  things, satisfaction  of  the
Minimum  Tender  Condition  and the  expiration  or termination  of  all waiting
periods imposed by the Hart-Scott-Rodino Antitrust Improvements Act of 1976  and
the  regulations under it (the "HSR Act").  The Offer also is subject to certain
other conditions set  forth in Section  14 below.  Subject to the  terms of  the
Merger  Agreement, the Purchaser  expressly reserves the right  (but will not be
obligated) to waive any or  all of the conditions of  the Offer. Subject to  the
terms  of the  Merger Agreement,  if by the  Expiration Date  any or  all of the
conditions of the Offer are not  satisfied or waived, the Purchaser will  extend
the period during which the Offer is open until the earliest of the consummation
of  the  Offer, November  30, 1995  (provided,  that the  Purchaser will  not be
obligated to  make  any such  extension  if, in  the  reasonable belief  of  the
Purchaser, all of the conditions of the Offer are not capable of being satisfied
by that date) or the termination of the Merger Agreement.

    Subject  to  the  terms of  the  Merger Agreement,  the  Purchaser expressly
reserves the right,  subject to  applicable law, to  extend the  period of  time
during which the Offer is open, provided that the extension of the Offer will be
for  a period of no more  than 10 business days. There  can be no assurance that
the Purchaser will exercise  its right to extend  the Offer. The Purchaser  also
expressly  reserves the right, subject  to applicable laws (including applicable
regulations of the Commission promulgated under the Exchange Act) and the  terms
of  the  Merger Agreement,  at  any time  or  from time  to  time, (i)  to delay
acceptance for payment of or payment  for any Shares, regardless of whether  the
Shares  were theretofore accepted for payment, or to terminate the Offer and not
accept for payment or pay for any Shares not theretofore accepted for payment or
paid for, upon the occurrence of any  of the conditions specified in Section  14
below,  by giving oral or written notice of such delay in payment or termination
to the Depositary, and (ii) to amend the Offer in any respect, by giving oral or
written notice to the Depositary.  Any extension, delay in payment,  termination
or amendment will be followed as promptly as practicable by public announcement,
the  announcement in the  case of an extension  to be issued  no later than 9:00
a.m., New  York  City  time, on  the  next  business day  after  the  previously
scheduled  Expiration Date. Without  limiting the manner  in which the Purchaser
may choose  to  make  any  public  announcement,  the  Purchaser  will  have  no
obligation to publish, advertise or otherwise communicate any such announcement,
other  than by issuing a  release to the Dow Jones  News Service or as otherwise
required by  law.  The  reservation by  the  Purchaser  of the  right  to  delay
acceptance  for payment of or payment for Shares is subject to the provisions of
Rule 14e-1(c) under the Exchange Act, which requires that the Purchaser pay  the
consideration  offered  or  return  the  Shares deposited  by  or  on  behalf of
Stockholders promptly  after the  termination or  withdrawal of  the Offer.  Any
delay  in  acceptance  for  payment  or payment  beyond  the  time  permitted by
applicable law will be  effectuated by an extension  of the period during  which
the Offer is open.

    Pursuant  to the  terms of the  Merger Agreement, without  the prior written
consent of the Company, the Purchaser will  not (i) decrease or change the  form
of consideration payable in the Offer, (ii) decrease the number of Shares sought
pursuant  to the  Offer, (iii) impose  additional conditions to  the Offer, (iv)
change the  conditions to  the Offer,  (v)  waive the  condition that  there  be
validly  tendered and not properly withdrawn prior to the time the Offer expires
a number  of  Shares that  constitutes  a  majority of  the  Shares  outstanding
calculated  on a fully  diluted basis on the  date of purchase  or (vi) make any
other change in  the terms  or conditions  of the  Offer adverse  to holders  of
Shares;  provided that, except as  set forth above, the  Purchaser may waive any
other condition to the Offer in its sole discretion; and provided, further, that
the Offer may be extended in connection with an increase in the consideration to
be paid  pursuant  to the  Offer  so as  to  comply with  applicable  rules  and
regulations  of the Commission. Assuming the prior satisfaction or waiver of the
conditions to the Offer, the Purchaser will accept for payment, and pay for,  in
accordance  with the  terms of  the Offer, all  Shares validly  tendered and not
properly withdrawn pursuant to the Offer promptly after the Expiration Date.

    The Commission  has  announced  that,  under  its  interpretation  of  Rules
14d-4(c) and 14d-6(d) under the Exchange Act, material changes in the terms of a
tender  offer  or information  concerning a  tender offer  may require  that the
tender offer be extended so that it remains open a

                                       3
<PAGE>
sufficient period of time  to allow security holders  to consider such  material
changes  or information in deciding  whether or not to  tender or withdraw their
securities. The minimum period during which an offer must remain open  following
material  changes in the terms of the Offer or information concerning the Offer,
other than a change  in price or  a change in  percentage of securities  sought,
will depend upon the facts and circumstances, including the relative materiality
of the terms or information. If the Purchaser decides to increase or, subject to
the  consent of the Company, to decrease the consideration in the Offer, to make
a change in the percentage  of Shares sought or to  change or waive the  Minimum
Tender  Condition and, if, at  the time that notice of  any such change is first
published, sent or given  to Stockholders, the Offer  is scheduled to expire  at
any  time earlier than the tenth business  day after (and including) the date of
that notice, the Offer will  be extended at least  until the expiration of  that
period of ten business days.

    The  Company  has  provided  the Purchaser  with  its  stockholder  list and
security position  listings  for  the  purpose of  disseminating  the  Offer  to
Stockholders.  This Offer  to Purchase,  the related  Letter of  Transmittal and
other relevant materials will be mailed to record holders of Shares and will  be
furnished  to brokers,  dealers, commercial  banks, trust  companies and similar
persons whose names,  or the  names of whose  nominees, appear  on the  Company'
stockholder list or, if applicable, who are listed as participants in a clearing
agency's  security  position listing  for  subsequent transmittal  to beneficial
owners of Shares.

2.  ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES

    Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension  or
amendment),  the Purchaser will  accept for payment  (and thereby purchase) and,
under the terms of the Offer, pay  for Shares that are validly tendered and  not
properly  withdrawn on or prior to the Expiration Date, promptly after the later
of  the  following  dates:  (i)  the  Expiration  Date  and  (ii)  the  date  of
satisfaction  or waiver  of all the  conditions to  the Offer set  forth in this
Offer  to  Purchase.  The  Purchaser  expressly  reserves  the  right,  in   its
discretion,  subject to applicable laws and regulations, to delay acceptance for
payment of or payment for Shares in order  to comply, in whole or in part,  with
any  applicable law, government regulation or  condition contained in this Offer
to Purchase. See Section 14 below.

    In all cases,  payment for Shares  purchased pursuant to  the Offer will  be
made  only after timely  receipt by the  Depositary of (i)  certificates for the
Shares (or  a timely  Book-Entry Confirmation  (as defined  in Section  3)  with
respect  to the Shares) and (ii) the Letter of Transmittal (or a manually signed
facsimile), properly completed  and duly  executed with  all required  signature
guarantees,  and all other documents required  by the Letter of Transmittal. See
Section 3 below.

    For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment (and thereby purchased)  tendered Shares as, if  and when the  Purchaser
gives  oral or written notice to the Depositary of the Purchaser's acceptance of
the Shares for payment. In all  cases, payment for Shares purchased pursuant  to
the  Offer will be  made by deposit  of the purchase  price with the Depositary,
which will act as agent for tendering Stockholders for the purpose of  receiving
payment  from the Purchaser  and transmitting payment  to tendering Stockholders
whose Shares  shall  have  been  accepted  for  payment.  If,  for  any  reason,
acceptance  for payment of any Shares tendered pursuant to the Offer is delayed,
or the Purchaser is unable to accept for payment Shares tendered pursuant to the
Offer, then, without prejudice to the  Purchaser's rights under Section 14,  the
Depositary  may,  nevertheless,  on  behalf of  the  Purchaser,  retain tendered
Shares, and such  Shares may not  be withdrawn,  except to the  extent that  the
tendering Stockholders are entitled to withdrawal rights as described in Section
4 below and as otherwise required by Rule 14e-1(c) under the Exchange Act. Under
no  circumstances will  interest on  the Offer Price  be paid  by the Purchaser,
regardless of any delay in making such payment.

    If any tendered Shares are not  purchased for any reason or if  certificates
are submitted for more Shares than are tendered, certificates for the Shares not
purchased or tendered will be returned

                                       4
<PAGE>
pursuant to the instructions of the tendering Stockholder without expense to the
tendering  Stockholder  (or,  in  the case  of  Shares  delivered  by book-entry
transfer into the  Depositary's account  at a Book-Entry  Transfer Facility  (as
defined  in Section 3)  pursuant to the  procedures set forth  in Section 3, the
Shares will be credited to an  account maintained at the appropriate  Book-Entry
Transfer   Facility)  as  promptly  as  practicable  following  the  expiration,
termination or withdrawal of the Offer.

    If, prior to the Expiration Date, the Purchaser increases the  consideration
to be paid per Share pursuant to the Offer, the Purchaser will pay the increased
consideration for all the Shares purchased pursuant to the Offer, whether or not
the Shares were tendered prior to the increases in consideration.

    The  Purchaser reserves the  right to transfer  or assign, in  whole or from
time to time in  part, to one or  more of its affiliates  the right to  purchase
Shares  tendered pursuant to  the Offer; however no  such transfer or assignment
will release the Purchaser from its obligations under the Offer or prejudice the
rights of tendering Stockholders to receive payment for Shares validly  tendered
and accepted for payment pursuant to the Offer.

3.  PROCEDURE FOR TENDERING SHARES

    VALID  TENDERS.  For  Shares to be  validly tendered pursuant  to the Offer,
either (i) a Letter  of Transmittal (or a  manually signed facsimile),  properly
completed  and duly  executed, with  any required  signature guarantees  and any
other documents required by the Letter  of Transmittal, must be received by  the
Depositary  at one of its addresses set forth on the back cover of this Offer to
Purchase prior to the Expiration  Date and either (a) certificates  representing
Shares  must be  received by  the Depositary  at any  such address  prior to the
Expiration Date or (b) the Shares  must be delivered pursuant to the  procedures
for  book-entry  transfer  set forth  below  and a  Book-Entry  Confirmation (as
defined below) must be received by  the Depositary prior to the Expiration  Date
or  (ii)  the tendering  Stockholder must  comply  with the  guaranteed delivery
procedures set forth  below. No alternative,  conditional or contingent  tenders
will be accepted.

    BOOK-ENTRY  TRANSFER.  The Depositary will establish an account with respect
to the Shares at The Depository Trust Company, Midwest Securities Trust  Company
and   Philadelphia  Depository  Trust  Company  (each,  a  "Book-Entry  Transfer
Facility" and, collectively, the "Book-Entry Transfer Facilities") for  purposes
of  the Offer within two business days after the date of this Offer to Purchase.
Any financial  institution  that is  a  participant  in any  of  the  Book-Entry
Transfer Facilities' systems may make book-Entry delivery of Shares by causing a
Book-Entry  Transfer  Facility  to  transfer the  Shares  into  the Depositary's
account at the Book-Entry Transfer  Facility in accordance with that  Book-Entry
Transfer  Facility's procedures for such transfer. However, although delivery of
the Shares may  be effected  through book-entry transfer  into the  Depositary's
account  at  a Book-Entry  Transfer Facility,  the Letter  of Transmittal  (or a
manually signed  facsimile),  properly completed  and  duly executed,  with  any
required  signature guarantees  and any other  required documents,  must, in any
case, be transmitted to, and received by, the Depositary at one of its addresses
set forth on the back  cover of this Offer to  Purchase prior to the  Expiration
Date,  or the  tendering Stockholder  must comply  with the  guaranteed delivery
procedures described below. The confirmation of a book-entry transfer of  Shares
into  the Depositary's  account at a  Book-Entry Transfer  Facility as described
above is referred to as a "Book-Entry Confirmation". DELIVERY OF DOCUMENTS TO  A
BOOK-ENTRY   TRANSFER  FACILITY  IN  ACCORDANCE  WITH  THE  BOOK-ENTRY  TRANSFER
FACILITY'S PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.

    SIGNATURE GUARANTEES.    Signatures  on  Letters  of  Transmittals  must  be
guaranteed  by  a  member  firm of  a  registered  national  securities exchange
(registered under Section 6 of the Exchange Act) or of the National  Association
of  Securities Dealers,  Inc. (the  "NASD"), or  by a  commercial bank  or trust
company having an office or correspondent in  the United States or by any  other
"Eligible  Guarantor Institution" (as defined in Rule 17Ad-15 under the Exchange
Act) (each of the foregoing constituting an "Eligible Institution"), unless  the
Shares  are tendered (i) by a registered  holder of Shares who has not completed
either the  box entitled  "Special Delivery  Instructions" or  the box  entitled
"Special  Payment Instructions"  on the  Letter of  Transmittal or  (ii) for the
account of  an  Eligible  Institution.  See  Instruction  1  of  the  Letter  of
Transmittal.   If  the  certificates  representing   Shares  are  registered  in

                                       5
<PAGE>
the name of a person  other than the signer of  the Letter of Transmittal or  if
payment is to be made or certificates for Shares not accepted for payment or not
tendered are to be issued to a person other than the registered holder, then the
certificates  representing Shares must be endorsed or accompanied by appropriate
stock powers, in each case signed exactly as the name or names of the registered
holder or  holders  appear on  the  certificates,  with the  signatures  on  the
certificates  or stock powers  guaranteed as described above  and as provided in
the  Letter  of  Transmittal.  See  Instructions  1  and  5  of  the  Letter  of
Transmittal.

    GUARANTEED  DELIVERY.  If a Stockholder  wishes to tender Shares pursuant to
the Offer and the  Stockholder's certificates are  not immediately available  or
the  procedures for book-entry transfer cannot be completed on a timely basis or
time will not permit all required documents to reach the Depositary prior to the
Expiration Date, the Shares may nevertheless  be tendered, if all the  following
guaranteed delivery procedures are complied with:

        (i) the tender is made by or through an Eligible Institution;

        (ii)  a  properly  completed  and  duly  executed  Notice  of Guaranteed
    Delivery, substantially  in the  form provided  by the  Purchaser with  this
    Offer  to Purchase, is received by the Depositary as provided below prior to
    the Expiration Date; and

       (iii) the  certificates  for  all  tendered Shares  in  proper  form  for
    transfer  or a Book-Entry Confirmation with  respect to all tendered Shares,
    together with a properly completed  and duly executed Letter of  Transmittal
    (or  a manually  signed facsimile) and  any other documents  required by the
    Letter of Transmittal, are received  by the Depositary within three  NASDAQ/
    National  Market  System  ("NASDAQ/NMS")  trading  days  after  the  date of
    execution of the Notice of Guaranteed Delivery.

    The Notice of Guaranteed Delivery may be delivered by hand or transmitted by
telegram, facsimile transmission or mailed to the Depositary and must include an
endorsement by an Eligible Institution  in the form set  forth in the Notice  of
Guaranteed Delivery.

    In all cases, Shares shall not be deemed validly tendered, unless a properly
completed  and  duly  executed  Letter  of  Transmittal  (or  a  manually signed
facsimile) is received by the Depositary.

    The method of delivery of certificates for Shares, the Letter of Transmittal
and any other  required documents is  at the  option and risk  of the  tendering
Stockholder.  If delivery is  made by mail, registered  mail with return receipt
requested, properly  insured,  is recommended.  In  all cases,  sufficient  time
should be allowed to ensure timely delivery.

    Notwithstanding  any other provision of this  Offer to Purchase, payment for
Shares accepted for payment pursuant to the Offer in all cases will be made only
after timely  receipt  by the  Depositary  of certificates  for  (or  Book-Entry
Confirmation with respect to) the Shares, a Letter of Transmittal (or a manually
signed  facsimile),  properly completed  and  duly executed,  with  any required
signature  guarantees  and  all  other  documents  required  by  the  Letter  of
Transmittal.

    BACKUP FEDERAL INCOME TAX WITHHOLDING.  To prevent backup federal income tax
withholding  of 31%  of the  payments made to  Stockholders with  respect to the
purchase price  of Shares  purchased pursuant  to  the Offer  or the  Merger,  a
Stockholder must provide the Depositary with his correct taxpayer identification
number  and  certify  that  he  is not  subject  to  backup  federal  income tax
withholding by completing  the substitute  Form W-9  included in  the Letter  of
Transmittal.  See Instruction  10 of  the Letter  of Transmittal.  See Section 5
below.

    DETERMINATION OF VALIDITY.   All questions as to  the form of documents  and
the validity, eligibility (including time of receipt) and acceptance for payment
of  any tender of Shares pursuant to  any of the procedures described above will
be determined by the Purchaser in its sole discretion, which determination shall
be final and binding on all  parties. The Purchaser reserves the absolute  right
to  reject any or all tenders  of Shares determined not to  be in proper form or
the acceptance  of or  payment for  which may,  in the  opinion of  counsel,  be
unlawful   and   reserves   the  absolute   right   to  waive   any   defect  or

                                       6
<PAGE>
irregularity in  any  tender of  Shares.  Subject to  the  terms of  the  Merger
Agreement,  the Purchaser also reserves the absolute right to waive or amend any
or all of  the conditions of  the Offer. The  Purchaser's interpretation of  the
terms  and conditions of the Offer (including  the Letter of Transmittal and its
instructions) will be final and binding on all parties. No tender of Shares will
be deemed to have been validly  made, until all defects and irregularities  have
been  cured  or waived.  None of  the  Purchaser, the  Sub, the  Depositary, the
Information  Agent  or  any  other  person  will  be  under  any  duty  to  give
notification  of any defects or irregularities in tenders or incur any liability
for failure to give any such notification.

    OTHER REQUIREMENTS.   By  executing  a Letter  of Transmittal,  a  tendering
Stockholder   irrevocably   appoints   designees  of   the   Purchaser   as  his
attorneys-in-fact and proxies, with  full power of  substitution, in the  manner
set  forth in the Letter of Transmittal, to the full extent of the Stockholder's
rights with respect to the Shares  tendered by the Stockholder and purchased  by
the  Purchaser and with respect to any  and all other Shares or other securities
issued or issuable  in respect  of those  Shares, on or  after the  date of  the
Offer.  All such powers of attorney and  proxies will be considered coupled with
an interest in the tendered Shares. Such appointment will be effective when, and
only to the  extent that,  the Purchaser accepts  the Shares  for payment.  Upon
acceptance  for payment, all prior  powers of attorney and  proxies given by the
Stockholder with respect to the Shares (and any other Shares or other securities
so issued in respect of such purchased Shares) will be revoked, without  further
action,  and no subsequent powers of attorney  and proxies may be given (and, if
given, will not be  deemed effective) by the  Stockholder. The designees of  the
Purchaser  will be  empowered to  exercise all  voting and  other rights  of the
Stockholder with respect to such Shares  (and any other Shares or securities  so
issued in respect of such purchased Shares) as they in their sole discretion may
deem  proper, including, without limitation, in respect of any annual or special
meeting of the  Stockholders, or  any adjournment  or postponement  of any  such
meeting, or in connection with any action by written consent in lieu of any such
meeting or otherwise (including any such meeting or action by written consent to
approve  the Merger). The Purchaser reserves the absolute right to require that,
in order  for  Shares  to  be validly  tendered,  immediately  upon  Purchaser's
acceptance  for payment of  the Shares, the  Purchaser must be  able to exercise
full voting and other rights with respect to the Shares, including voting at any
meeting of Stockholders then scheduled.

    A tender of Shares  pursuant to any of  the procedures described above  will
constitute the tendering Stockholder's acceptance of the terms and conditions of
the Offer, as well as the tendering Stockholder's representation and warranty to
the  Purchaser that (i)  the Stockholder has  a net long  position in the Shares
being tendered, within  the meaning of  Rule 14e-4 under  the Exchange Act,  and
(ii)  the tender of  the Shares complies with  Rule 14e-4. It  is a violation of
Rule 14e-4 for a person,  directly or indirectly, to  tender Shares for his  own
account,  unless, at the time  of tender, the person so  tendering (i) has a net
long position equal to or greater than the amount of (a) Shares tendered or  (b)
other securities immediately convertible into or exchangeable or exercisable for
the  Shares  tendered and  that person  will  acquire the  Shares for  tender by
conversion, exchange or exercise and (ii) will cause the Shares to be  delivered
in  accordance  with the  terms  of the  Offer.  Rule 14c-4  provides  a similar
restriction applicable  to the  tender or  guarantee of  a tender  on behalf  of
another  person.  The  Purchaser's  acceptance for  payment  of  Shares tendered
pursuant to the Offer will constitute a binding agreement between the  tendering
Stockholder and the Purchaser upon the terms and conditions of the Offer.

4.  WITHDRAWAL RIGHTS

    Tenders  of Shares  made pursuant  to the  Offer are  irrevocable, except as
otherwise provided in this Section 4. Shares tendered pursuant to the Offer  may
be  withdrawn at any time  prior to the Expiration  Date and, unless theretofore
accepted for payment by the Purchaser as provided in this Offer to Purchase, may
also be withdrawn at any  time after October 2,  1995. If the Purchaser  extends
the  Offer, is delayed in its purchase of  or payment for Shares or is unable to
purchase or pay for Shares

                                       7
<PAGE>
for any reason, then, without prejudice to the rights of the Purchaser, tendered
Shares may be retained by the Depositary on behalf of the Purchaser and may  not
be  withdrawn, except to the extent  that tendering Stockholders are entitled to
withdrawal rights as set forth in this Section 4.

    The reservation by  the Purchaser of  the right to  delay the acceptance  or
purchase  of or payment for Shares is subject to the provisions of Rule 14e-1(c)
under the Exchange Act,  which requires the Purchaser  to pay the  consideration
offered  or return  Shares deposited  by or  on behalf  of Stockholders promptly
after the termination or withdrawal of the Offer.

    For a  withdrawal  to be  effective,  a written,  telegraphic  or  facsimile
transmission  notice of withdrawal must be  timely received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase.  Any
such  notice of withdrawal must specify the name of the persons who tendered the
Shares to be withdrawn, the number of Shares to be withdrawn and the name of the
registered holder, if different from that of the person who tendered the Shares.
If certificates evidencing Shares have been delivered or otherwise identified to
the Depositary, then, prior  to the release of  the certificates, the  tendering
Stockholder  must  also  submit  the  serial  numbers  shown  on  the particular
certificates evidencing the  Shares to be  withdrawn, and the  signature on  the
notice  of withdrawal must  be guaranteed by an  Eligible Institution (except in
the case of  Shares tendered  for the account  of an  Eligible Institution).  If
Shares  have been tendered pursuant to the procedure for book-entry transfer set
forth in Section 3, the notice of withdrawal must specify the name and number of
the account at the applicable Book-Entry  Transfer Facility to be credited  with
the  withdrawn Shares. All questions as to the form and validity (including time
of receipt) of notices of withdrawal will be determined by the Purchaser, in its
sole discretion, whose determination will be  final and binding on all  parties.
No  withdrawal of  Shares will be  deemed to  have been properly  made until all
defects and irregularities have been cured or waived. None of the Purchaser, the
Sub, the Depositary, the Information Agent or any other person will be under any
duty to give  notification of  any defects or  irregularities in  any notice  of
withdrawal or incur any liability for failing to give such notification.

    Any  Shares  properly  withdrawn will  be  deemed not  validly  tendered for
purposes of the Offer, but may be  tendered at any subsequent time prior to  the
Expiration Date by following any of the procedures described in Section 3 above.

5.  CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE OFFER AND THE MERGER

    The  following is a summary of the principal federal income tax consequences
of the Offer and the  Merger to holders whose  Shares are purchased pursuant  to
the  Offer or whose  Shares are converted  into the right  to receive the Merger
Consideration in the Merger (including  any cash amounts received by  dissenting
Stockholders  pursuant  to the  exercise  of appraisal  rights).  The discussion
applies only to holders of Shares in whose hands Shares are capital assets,  and
may  not apply  to Shares  received pursuant to  the exercise  of employee stock
options or  otherwise as  compensation, or  to  holders of  Shares who  are  not
citizens or residents of the United States.

    The federal income tax consequences set forth below are included for general
informational  purposes only and are based  upon present law. Because individual
circumstances may  differ, each  holder of  Shares should  consult his  own  tax
advisor  to determine  the applicability  of the  rules discussed  below to that
Stockholder and  the  particular  tax  effects of  the  Offer  and  the  Merger,
including the application and effect of state, local and other tax laws.

    The  receipt of the Offer Price  and the Merger Consideration (including any
cash amounts received  by dissenting  Stockholders pursuant to  the exercise  of
appraisal  rights) will be a taxable transaction for federal income tax purposes
(and also may be a taxable  transaction under applicable state, local and  other
income  tax laws).  In general,  for federal  income tax  purposes, a  holder of
Shares will recognize gain or loss equal to the difference between his  adjusted
tax  basis in the Shares sold pursuant to  the Offer or converted to cash in the
Merger and the amount of cash received therefor. Gain or loss must be determined
separately for  each  block  of  Shares  (I.E.,  Shares  acquired  at  the  same

                                       8
<PAGE>
cost in a single transaction) sold pursuant to the Offer or converted to cash in
the Merger. Such gain or loss will be capital gain or loss and will be long-term
gain  or loss,  if, on  the date  of sale  (or, if  applicable, the  date of the
Merger), the Shares were held for more than one year.

    Payments in  connection with  the Offer  or  the Merger  may be  subject  to
"backup  withholding" at a 31% rate. Backup withholding generally applies if the
Stockholder (i) fails to  furnish his social security  number or other  taxpayer
identification  number  ("TIN"), (ii)  furnishes an  incorrect TIN,  (iii) fails
properly to report interest  or dividends or  (iv) under certain  circumstances,
fails  to provide a certified statement, signed under penalties of perjury, that
the TIN provided  is his correct  number and that  he is not  subject to  backup
withholding.  Backup withholding is not an  additional tax but merely an advance
payment, which may be  refunded to the  extent it results  in an overpayment  of
tax.  Certain persons  generally are  exempt from  backup withholding, including
corporations and financial institutions. Certain penalties apply for failure  to
furnish  correct information and for failure  to include the reportable payments
in income. Each Stockholder should  consult with his own  tax advisor as to  his
qualifications  for exemption from  withholding and the  procedure for obtaining
such exemption.

6.  PRICE RANGE OF THE SHARES; DIVIDENDS ON THE SHARES

    According to the  Company, the  Shares commenced trading  on the  NASDAQ/NMS
under  the symbol  "MSAM" on  March 26,  1987. The  Company has  never paid cash
dividends on  the  Shares. The  following  table  sets forth,  for  the  periods
indicated, the high and low sale prices per Share on the NASDAQ/NMS.

           Second Quarter..................................................................  13 1/4      8
           Third Quarter...................................................................  15          9 3/4

           Third Quarter (through August 3)................................................  21 1/4     18 1/2
</TABLE>

    On  July 28, 1995, the  last full day before  the public announcement of the
Purchaser's intention to acquire the Shares, the closing bid price per Share  on
the NASDAQ/NMS was $19 5/16. On August 3, 1995, the last full trading day before
the commencement of the Offer, the closing bid price per Share on the NASDAQ/NMS
was  $20  3/4  per  Share.  Stockholders  are  urged  to  obtain  current market
quotations for the Shares.

7.  EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES, NASDAQ/NMS LISTING,
    EXCHANGE ACT REGISTRATION AND MARGIN SECURITIES

    The purchase  of Shares  pursuant to  the Offer  will reduce  the number  of
holders  of Shares and the number of  Shares that might otherwise trade publicly
and could  adversely affect  the liquidity  and market  value of  the  remaining
Shares held by the public.

    The  extent  of the  public  market for  the  Shares and,  according  to the
published guidelines of  the NASD, the  continued trading of  the Shares on  the
NASDAQ/NMS, after commencement of the Offer,

                                       9
<PAGE>
will  depend upon the  number of holders  of Shares remaining  at that time, the
interest in maintaining a market in the Shares on the part of securities  firms,
the  possible termination of registration of  the Shares under the Exchange Act,
as described below, and other factors.

    The Company has informed the Purchaser that, as of July 26, 1995, 11,084,137
Shares were outstanding. If, as a result  of the purchase of Shares pursuant  to
the Offer or otherwise, trading of the Shares on the NASDAQ/NMS is discontinued,
the  liquidity of  and market  for the Shares  could be  adversely affected. The
Purchaser cannot predict whether or to  what extent the reduction in the  number
of  Shares  that  might  otherwise  trade  publicly  would  have  an  adverse or
beneficial effect on  the market  price for or  marketability of  the Shares  or
whether it would cause future prices to be greater or less than the Offer Price.

    The Shares are currently registered under Section 12(g) of the Exchange Act.
Registration  of  the  Shares under  the  Exchange  Act may  be  terminated upon
application by the Company to the  Commission, if the Shares are neither  listed
on  a national securities exchange nor held  by more than 300 holders of record.
Termination  of  registration  of  the  Shares  under  the  Exchange  Act  would
substantially  reduce the information required to be furnished by the Company to
its Stockholders and to the Commission and could make certain provisions of  the
Exchange Act no longer applicable to the Company, such as the short-swing profit
recovery  provisions of  Section 16(b) of  the Exchange Act,  the requirement of
furnishing a proxy statement  pursuant to Section 14(a)  of the Exchange Act  in
connection with Stockholders' meetings and the related requirement of furnishing
an  annual report to Stockholders  and the requirements of  Rule 13e-3 under the
Exchange Act  with respect  to "going  private" transactions.  Furthermore,  the
ability   of  "affiliates"  of  the  Company  and  persons  holding  "restricted
securities" of the Company to dispose of securities pursuant to Rule 144 or 144A
under the Securities Act of 1933 may be impaired or eliminated.

    The Purchaser  intends  to  seek  to cause  the  Company  to  terminate  the
registration  of the Shares under the Exchange  Act as soon after the completion
of the Offer as the requirements for termination are met. If registration of the
Shares is not  terminated prior to  the Merger, the  registration of the  Shares
under the Exchange Act will be terminated following consummation of the Merger.

    The  Shares are currently  "margin securities" under  the regulations of the
Board of Governors of the Federal Reserve System (the "Federal Reserve  Board"),
which  has the effect, among other things,  of allowing brokers to extend credit
on the  loan  value of  the  Shares. Depending  upon  factors similar  to  those
described  above regarding listing  and market quotations,  it is possible that,
following the Offer, the Shares  would no longer constitute "margin  securities"
for  the purpose  of the  margin regulations  of the  Federal Reserve  Board and
therefore could no longer be  used as collateral for  loans made by brokers.  If
registration  of Shares under the Exchange Act were terminated, the Shares would
no longer be "margin securities" or be eligible for listing on the NASDAQ/NMS.

    CERTAIN COMPANY PROJECTIONS.  During  the course of discussions between  the
Purchaser and the Company that led to the execution of the Merger Agreement (see
Section  11 below), in May 1995 the  Company provided the Purchaser with certain
non-public business and financial information about the Company. Included  among
the  information  the  Company  provided  the  Purchaser  were  projections that
indicated 1995,  1996,  1997  and  1998 net  revenue  of  $48.3  million,  $71.3
milllion,  $94.1 million and $120.1 million,  respectively, and 1995, 1996, 1997
and 1998  net income  of $4.7  million, $9.6  million, $16.2  million and  $25.2

    Martin  Sperber, the Purchaser's  chairman and chief  executive officer, has
owned 3,125 Shares  for a  number of  years, and  has advised  the Purchaser  he
intends  to tender all such Shares pursuant to the Offer. Except as described in
this Offer to  Purchase, (i)  none of  the Purchaser, the  Sub or,  to the  best
knowledge  of the Purchaser and the Sub, any of the persons listed in Schedule I
or any associate or majority-owned  subsidiary of any such person,  beneficially
owns  or has a right to acquire any equity security of the Company and (ii) none
of the Purchaser, the  Sub or, to  the best knowledge of  the Purchaser and  the
Sub,  any  of the  other persons  referred to  above, or  any of  the respective
directors, executive  officers or  subsidiaries  of any  of the  foregoing,  has
effected  any transaction in any equity security  of the Company during the past
60 days.

    Except as described in  this Offer to Purchase,  (i) none of the  Purchaser,
the  Sub or,  to the best  knowledge of  the Purchaser and  the Sub,  any of the
persons listed in  Schedule I  has any contract,  arrangement, understanding  or
relationship  (whether or  not legally enforceable)  with any  other person with
respect to any  securities of the  Company, including, but  not limited to,  any
contract,  arrangement, understanding or relationship concerning the transfer or
the voting of any such securities, joint ventures, loan or option  arrangements,
puts  or calls, guarantees  of loans, guarantees  against loss or  the giving or
withholding of proxies  and (ii) there  have been no  contacts, negotiations  or
transactions  between  the  Purchaser,  the  Sub  or  any  of  their  respective
subsidiaries or, to the best knowledge of the Purchaser and the Sub, any of  the
persons  listed in Schedule  I, on the one  hand, and the Company  or any of its
directors, officers or affiliates,  on the other hand,  that are required to  be
disclosed pursuant to the rules and regulations of the Commission.

10.  SOURCE AND AMOUNT OF FUNDS

    The  total  amount  of  funds  required by  the  Purchaser  and  the  Sub to
consummate the Offer  and the Merger  and to  pay related fees  and expenses  is
estimated  to be approximately $258 million. The Sub intends to obtain the funds
required by it from capital contributions and/or loans from the Purchaser.

    The Purchaser will  obtain all of  those funds from  credit facilities.  The
Purchaser  has  received  a commitment  letter  dated  June 6,  1995  (the "Bank
Commitment Letter") from Chemical to provide senior secured term loan facilities
and senior secured  revolving credit facilities  for up to  $350 million (i)  to
finance  the purchase of the Shares pursuant to  the Offer and Merger and to pay
certain related  fees and  expenses related  to the  Offer and  Merger, (ii)  to
refinance  certain existing debt of the  Purchaser and (iii) for working capital
purposes. Consummation of that financing is subject to, among other things,  the
receipt of required consents, the absence of material adverse conditions and the
negotiation,  execution and delivery of definitive documentation consistent with
the Bank Commitment Letter and the related term sheet. There can be no assurance
that the terms described in the Bank Commitment Letter will be contained in  the
definitive  agreements  or  that  the  definitive  agreements  will  not contain
additional provisions.

    The Bank Commitment Letter and the  related term sheet attached provide  for
credit  facilities relating to the Offer consisting  of a $250 million term loan
facility (the "Facility A")  and a $100 million  revolving credit facility  (the
"Facility  B"), which mature on  the earlier of the  Effective Date and the date
270 days after the first date on which Shares are accepted for purchase pursuant
to the Offer. In addition, facilities relating  to the Merger will consist of  a
$250  million term  loan facility  ("Facility C")  and a  $100 million revolving
credit facility  (the "Facility  D"), which  mature on  December 31,  2001.  The
Purchaser  has agreed to assist Chemical  in syndicating Facility A, Facility B,
Facility C and Facility D (collectively, the "Facilities").

                                       13
<PAGE>
    The  Facilities  will  be guaranteed  by  each of  the  Purchaser's domestic
subsidiaries and, subject to  standards to be agreed  upon by the Purchaser  and
Chemical,  certain of the Purchaser's foreign  subsidiaries. The loans under the
Facilities and  the guarantees  will be  secured  by (i)  all the  Shares  owned
directly  or  indirectly by  the  Purchaser and  all  the common  stock  of each
subsidiary of the  Purchaser that is  a guarantor and  approximately 65% of  the
common  stock of foreign, non-guarantor  subsidiaries and (ii) substantially all
assets of the Purchaser and its domestic subsidiaries.

    The Facilities will bear  interest, depending on  the interest rate  pricing
option selected by the Purchaser, at LIBOR, Prime Rate, Base CD plus one percent
per  annum or Federal Funds Effective Rate  plus one-half of 1 percent per annum
(the Prime Rate, Base CD plus one percent per annum and Federal Funds  Effective
Rate  plus one-half of 1 percent per annum being collectively referred to as the
"Alternate Base Rate"). A margin of one  and one-quarter of 1 percent per  annum
and one-quarter of 1 percent per annum will be added to LIBOR and Alternate Base
Rate  loans, respectively,  effected pursuant to  Facilities A and  B. A sliding
scale margin for loans effected pursuant to Facilities C and D will be added  to
the selected rate option based on leverage and interest expense coverage ratios,
which,  for LIBOR-based loans, will be up  to one and one-half percent per annum
and, for Alternate  Base Rate loans,  will be up  to one-half of  1 percent  per
annum.  A commitment  fee on the  undrawn amount of  Facilities A and  B will be
payable at a per annum rate of three-eighths of 1 percent and at a sliding  rate
of one-quarter to one-half of 1 percent in the case of Facilities C and D.

    It  presently is anticipated that funds  borrowed under the Facilities would
be repaid from internally  generated funds of the  Purchaser or the Company,  or
with the proceeds of a subsequent or other financing transaction.

    The  margin  regulations  promulgated  by the  Federal  Reserve  Board place
restrictions on the amount of  credit that may be  extended for the purposes  of
purchasing  margin  stock  (including  the Shares),  if  the  credit  is secured
directly or indirectly by margin stock. The Purchaser believes the financing  of
the   acquisition  of  the  Shares  will  be  in  full  compliance  with  margin
regulations, as applicable.

11.  BACKGROUND OF THE OFFER

    In recent years, the Purchaser and the Company have engaged in business with
each other. In that connection, in 1992,  1993 and 1994, the Company made  sales
to the Purchaser of $1,139,454, $1,952,688 and $183,237, respectively.

    From  time to time over the past few years, Martin Sperber, the chairman and
chief executive  officer of  the  Purchaser, and  Marvin Samson,  the  Company's
president,  also briefly discussed the possibility  of the two companies working
together in other ways. These discussions included a meeting on May 8, 1995  and
a  telephone conversation on May  12, 1995, in which  Mr. Sperber and Mr. Samson
discussed the possibility of the  two companies combining. Subsequently, in  May
1995,  representatives  of  Tanner  &  Co.,  Inc.  ("Tanner"),  the  Purchaser's
financial advisor, and Bear Stearns, the Company's financial advisor,  discussed
the  Purchaser's possible  acquisition of  the Company.  In that  connection, in
mid-May, the Purchaser executed a confidentiality agreement with the Company  in
anticipation of receiving information concerning the Company.

    At  a meeting on  May 17, 1995  among representatives of  the Purchaser, the
Company, Tanner and Bear Stearns, the Purchaser's representatives indicated  the
Purchaser  was interested in pursuing an acquisiton of the Company at a price of
$19.50 a  Share. In  a letter  dated May  31, 1995  to Mr.  Samson, Mr.  Sperber
reaffirmed  the Purchaser's interest, subject to due diligence, in acquiring the
Company for $19.50 a Share and, if appropriate, going beyond $19.50. In a letter
dated June 1, 1995, as a follow-up  to his previous letter, Mr. Sperber  advised
Mr.  Samson that, in anticipation of receiving due diligence material that would
justify a higher  price, the Purchaser  was prepared to  increase its number  to
$21.00 a Share, and might consider going higher.

                                       14
<PAGE>
    In  early  June,  the  Company  began  to  furnish  the  Purchaser  and  its
representatives  with  information  about   the  Company,  including   financial
information and information relating to manufacturing, sales and distribution of
the  Company's products  and other  relevant data  (in addition  to the publicly
available information the Purchaser already had). Throughout June and July,  the
Purchaser and its representatives conducted their due diligence investigation of
the  Company,  and  representatives  of  the  Purchaser  and  Tanner  engaged in
continuing discussions  with representatives  of the  Company and  Bear  Stearns
regarding that process.

    During  early June, the Purchaser negotiated  the terms of its financing for
the possible acquisition. On  June 7, representatives  of the Purchaser,  Tanner
and  the  Purchaser's  counsel met  with  representatives of  the  Company, Bear
Stearns and the Company's  counsel. At that meeting,  the parties discussed  the
Purchaser's  financing for a possible  acquisition, and the Purchaser reaffirmed
its interest  in  proceeding with  due  diligence with  a  view to  effecting  a
possible acquisition transaction.

    During  early June, Mr. Sperber, Mr.  Samson and Agnes Varis, the beneficial
owner of  approximately 14%  of the  outstanding Shares  and a  director of  the
Company, discussed the Company, the possible transaction and matters relating to
management  arrangements,  including  the Purchaser's  interest  in  the Company
having a substantial degree  of autonomy after the  acquisition. On June 11,  at
Mr. Sperber's request, Mr. Samson furnished the Purchaser a proposal relating to
the  Company's governance after  the acquisition, which  Mr. Sperber, Mr. Samson
and Ms. Varis continued to discuss thereafter. On June 19, Mr. Sperber,  Dariush
Ashrafi,  the Purchaser's senior vice president and chief financial officer, Mr.
Samson and Ms. Varis met to review those discussions.

    On June 8, drafts of the agreement  and plan of merger and the  stockholders
agreement  were delivered to the Company's  counsel. In late June, the Company's
counsel provided the Purchaser's counsel with  its comments on the June 8  draft
of the agreement and plan of merger.

    In  the course of discussions among the parties, the Purchaser had indicated
that its proposed acquisition was conditioned upon Mr. Samson and Ms. Varis (and
her affiliates) entering into the proposed stockholders agreement and Mr. Samson
entering into a  five-year employment  agreement. On  July 18,  counsel for  the
Company  and  the Purchaser  met and  discussed various  issues relating  to the
proposed transaction. On July  19, a draft of  an employment agreement with  Mr.
Samson was furnished by the Purchaser. From July 25 through July 28, the parties
negotiated  the agreement and  plan of merger and  the stockholders agreement as
well as the employment agreement with Mr. Samson.

    After confirming that the  representatives of the  Company and its  advisors
were  prepared to  recommend the  transaction to the  Board of  Directors of the
Company on  the  terms  described in  this  Offer  to Purchase,  the  Boards  of
Directors of the Purchaser and of the Company independently met and approved the
transaction on July 26 and July 28, respectively.

12.  PURPOSE OF THE OFFER AND THE MERGER; PLANS FOR THE COMPANY; THE MERGER
     AGREEMENT; THE STOCKHOLDERS AGREEMENT; OTHER AGREEMENTS

    PURPOSE OF THE OFFER AND THE MERGER

    The  purpose  of the  Offer and  the Merger  is to  enable the  Purchaser to
acquire, in one or more transactions, substantial control of the Company and the
entire equity interest in the Company.

    The Offer is  intended to increase  the likelihood that  the Merger will  be
completed  promptly. The Purchaser regards the  acquisition of the Company as an
attractive opportunity to acquire  a significant and well-established  business.
The  Purchaser  believes the  increased scale  of  the combined  businesses will
enable the Purchaser to compete more effectively in the pharmaceutical  business
both domestically and internationally.

                                       15
<PAGE>
    PLANS FOR THE COMPANY

    The Purchaser has identified several areas where it believes the Company and
the  Purchaser may enhance each other's  performance. The two business units, in
the  aggregate,  would  create  a  multisource  pharmaceutical  company  with  a
materially  broader product line than that of either business unit individually,
and the two business units would have complementary strengths.

    The Purchaser intends, from time to  time after completion of the Offer,  to
evaluate  and review the Company's operations and consider what, if any, changes
would be desirable in light of circumstances that then exist.

    Except as noted in this Offer to Purchase, the Purchaser and the Sub have no
present plans  or proposals  that  would result  in an  extraordinary  corporate
transaction,  such as a merger, reorganization,  liquidation or sale or transfer
of a material amount of assets, involving  the Company or any subsidiary or  any
other  material  changes  in  the  Company's  capitalization,  dividend  policy,
corporate structure, business or composition of its management or Board.

THE MERGER AGREEMENT

    The following is a  summary of the material  terms of the Merger  Agreement.
This  summary is not a  complete description of the  terms and conditions of the
Merger Agreement and is qualified in its entirety by reference to the full  text
of  the Merger Agreement, which is incorporated by reference and a copy of which
has been filed  with the Commission  as an  exhibit to the  Schedule 14D-1.  The
Merger Agreement may be examined, and copies obtained, as set forth in Section 8
above.

    THE OFFER.  The Merger Agreement provides for the commencement of the Offer,
in connection with which the Purchaser has expressly reserved the right to waive
certain  conditions of the Offer; however,  without the prior written consent of
the Company, the Purchaser has agreed not to (i) decrease or change the form  of
consideration  payable in the  Offer, (ii) decrease the  number of Shares sought
pursuant to the  Offer, (iii) impose  additional conditions to  the Offer,  (iv)
change  the  conditions to  the Offer,  (v)  waive the  condition that  there be
validly tendered and not properly withdrawn prior to the time the Offer  expires
a  number  of  Shares that  constitutes  a  majority of  the  Shares outstanding
calculated on a fully diluted  basis on the date of  purchase, or (vi) make  any
other  change in  the terms  or conditions  of the  Offer adverse  to holders of
Shares; provided that the Offer may  be extended in connection with an  increase
in  the consideration to be paid pursuant to the Offer to comply with applicable
rules and regulations of the Commission.

    BOARD REPRESENTATION.  The Merger Agreement provides that, promptly upon the
purchase by the Purchaser or any of its subsidiaries of a number of Shares  that
represents  at least a  majority of the  outstanding Shares (on  a fully diluted
basis), and from time to time thereafter, the Company, the Purchaser and the Sub
will, subject to the provisions  of section 14(f) of  the Exchange Act and  Rule
14f-1  under the Exchange Act, use all  reasonable efforts to cause the Board to
be comprised of Marvin Samson, Agnes  Varis, Allen Misher, three individuals  to
be  designated by the Purchaser and one  employee of Bayer Corporation or any of
its affiliates (other than the Purchaser and its subsidiaries) to be  designated
by  the Purchaser (subject to the approval  of Marvin Samson, which approval may
not be unreasonably withheld). Following the  date on which those persons  first
comprise  the Board (the "Control Date") and  prior to the Effective Time and as
long as  there  is at  least  one Continuing  Director  (defined in  the  Merger
Agreement as certain specified directors then in office who were directors as of
the  date of the Merger Agreement), if requested by a majority of the Continuing
Directors, all other directors will abstain  from acting upon, and the  approval
of  a majority of  the Continuing Directors  will be required  to authorize, any
termination of the Merger Agreement by the Company, any amendment of the  Merger
Agreement  requiring  action  by  the  Board,  any  extension  of  time  for the
performance of any obligation or other act of the Purchaser or the Sub under the
Merger Agreement and any waiver of  compliance with any provision of the  Merger
Agreement for the benefit
of the Company.

                                       16
<PAGE>
    CONSIDERATION TO BE PAID IN THE MERGER.  The Merger Agreement provides that,
upon  the  terms  (but  subject  to the  conditions)  set  forth  in  the Merger
Agreement, the Sub will be merged with and into the Company. In the Merger, each
Share issued and outstanding immediately prior to the Effective Time  (excluding
shares owned directly or indirectly by the Company or any of its subsidiaries or
by  the  Purchaser,  the  Sub  or any  other  subsidiary  of  the  Purchaser and
Dissenting Shares (as defined in the  Merger Agreement)) will be converted  into
the  right to receive in cash an amount per Share equal to the highest price per
Share payable in the Offer, without  any interest thereon, less any  withholding
taxes  required under Section  3406 of the  Internal Revenue Code  of 1986. Each
share of the capital stock of  the Sub issued and outstanding immediately  prior
to  the Effective  Time will  be converted  into and  become one  fully paid and
nonassessable share of Common Stock, par value $.01 per share, of the  Surviving
Corporation  (as defined in the Merger Agreement), which will thereupon become a
direct, wholly-owned subsidiary of the Purchaser. The Merger Agreement  provides
that  the Merger will occur as soon as practicable following the satisfaction or
waiver of conditions set forth in  the Merger Agreement. The Merger will  become
effective upon the filing of a certificate of merger in the State of Delaware or
at such time thereafter as is provided in the certificate of merger.

    STOCKHOLDER  MEETING.   The Merger Agreement  provides that,  if required by
applicable law, the Company will, as  soon as practicable following payment  for
the  Shares in  the Offer, duly  call a  meeting (the "Special  Meeting") of its
Stockholders for the purpose  of considering and taking  action upon the  Merger
Agreement  and the  transactions contemplated  by the  Merger Agreement.  At the
Special Meeting,  the Purchaser  will cause  all the  Shares then  owned by  the
Purchaser  or the Sub or and any of their subsidiaries or affiliates to be voted
in favor of the Merger.

    If the Purchaser  acquires at  least 90% of  the outstanding  Shares in  the
Offer,  the Merger  may be  effected without  a meeting  of the  Stockholders in
accordance with the provisions of Delaware law.

    REPRESENTATIONS AND  WARRANTIES.    The Merger  Agreement  contains  various
representations and warranties of the parties. These include representations and
warranties by the Company with respect to corporate existence and power, capital
structure,  corporate  authorization,  non-contravention  of  other  agreements,
documents and laws,  consents and approvals,  subsidiaries, Commission  filings,
compliance  with  applicable  laws,  litigation,  taxes,  regulatory compliance,
employee benefits,  material  liabilities,  environmental  matters,  absence  of
changes and other matters.

    The  Purchaser  and  the  Sub also  have  made  certain  representations and
warranties  with   respect  to   corporate   existence  and   power,   corporate
authorization and consents and approvals, non-contravention of other agreements,
documents and laws, regulatory matters, financing and other matters.

    CONDUCT  OF BUSINESS PENDING THE MERGER.   The Company has agreed that, from
the date of  the Merger  Agreement to the  Effective Time,  except as  otherwise
provided  in the Merger Agreement or consented  to by the Purchaser, the Company
and its subsidiaries  will conduct their  business only in  the ordinary  course
consistent  with past practice  and will use all  reasonable efforts to preserve
intact their business organizations and to maintain their existing relationships
with third  parties  with whom  they  have significant  business  relationships.
Except  as contemplated by the Merger  Agreement, the Company has further agreed
that it will not, nor will it permit any of its subsidiaries to: (i) issue, sell
or pledge, or authorize or propose  the issuance, sale or pledge of,  additional
shares  of  capital stock  of  any class  (including  the Shares)  or  any other
ownership interest in any of its subsidiaries, or securities convertible into or
exchangeable for any such shares or  ownership interest or any rights,  warrants
or  options to  acquire or  with respect  to any  such shares  of capital stock,
ownership interest or other convertible or exchangeable securities, or grant  or
accelerate  any right to convert or exchange  any securities for any such shares
(including the Shares) or ownership interest or any other securities in  respect
of,  in lieu of or in substitution for Shares outstanding, other than (a) Shares
issuable upon exercise of the Options  (as defined in the Merger Agreement)  and
(b)  issuances of capital stock of the  Company's subsidiaries to the Company or
to a wholly-owned subsidiary of the  Company; (ii) redeem or otherwise  acquire,
directly  or  indirectly,  any  of  its  outstanding  securities  (including the
Shares); (iii) split, combine  or reclassify its capital  stock or declare,  set
aside, make or pay any dividend or

                                       17
<PAGE>
distribution  on  any shares  of  capital stock  of the  Company  or any  of its
subsidiaries (other than cash dividends paid to the Company by its  wholly-owned
subsidiaries);  (iv) make any acquisition, by means of a merger or otherwise, of
assets or securities, or  any sale, lease, encumbrance  or other disposition  of
assets or securities, in each case other than in the ordinary course of business
and in circumstances not requiring approval of its board of directors; (v) incur
or  assume any debt for  borrowed money (other than  short-term debt pursuant to
existing credit facilities); (vi) assume, guarantee, endorse or otherwise become
liable  or  responsible  for  the  obligations  of  any  other  person   (except
wholly-owned  subsidiaries of  the Company),  except in  the ordinary  course of
business; (vii)  make  any  loans,  advances or  capital  contributions  to,  or
investments  in,  any  other  person (except  wholly-owned  subsidiaries  of the
Company), in each  case other than  in the ordinary  course of business;  (viii)
change  any of the accounting principles or practices used by the Company or any
of its subsidiaries, except  as required by the  Commission or by United  States
generally  accepted  accounting  principles;  (ix)  make  any  tax  election not
required by law or settle or compromise  any federal, state or local income  tax
liability,  in each case  that is material  to the Company  and its subsidiaries
taken as  a whole;  (x) adopt  any amendments  to the  Company's certificate  of
incorporation  or by-laws; (xi)  grant any stock-related  or performance awards;
(xii) forgive any loans to employees, officers or directors of more than $10,000
with respect to any particular individual; (xiii) enter into any new employment,
severance, consulting  or  salary  continuation agreements  with  any  officers,
directors or employees other than as contemplated by the Merger Agreement; (xiv)
adopt,  amend or  terminate any  material employee  benefit plan,  except in the
ordinary course of business or  as required by law  or as necessary to  maintain
tax  qualified status; or (xv) agree in writing  or otherwise to take any of the
foregoing actions or any action that  would make any representation or  warranty
in  the Merger Agreement untrue  or incorrect in any  material respect as of the
date when made or as of  a future date or otherwise  would result in any of  the
conditions to the Offer not being satisfied.

    OTHER  AGREEMENTS.  The  Company, the Purchaser  and the Sub  have agreed to
take all  reasonable  actions  necessary  to  comply  promptly  with  all  legal
requirements  that may have  been imposed on  it with respect  to the Offer, the
Merger  and  the  transactions   contemplated  by  the  Stockholders   Agreement
(including  furnishing  all  information  required  under  the  HSR  Act  and in
connection with approvals of or filings with any other governmental entity)  and
promptly  to cooperate with and furnish  information to each other in connection
with any such requirements imposed upon any of them or any of their subsidiaries
in connection with the  Offer, the Merger and  the transactions contemplated  by
the  Stockholders Agreement; provided that the  Purchaser need not so comply, if
required by the Department of Justice  or any other governmental entity to  hold
separate,  sell or otherwise dispose  of any subsidiary of  the Purchaser or the
Company or assets or  properties of any  of the foregoing,  the effect of  which
would  be materially to impair the value of the Merger to the Purchaser. Each of
the Company, the Purchaser and the Sub will, and will cause its subsidiaries to,
take all reasonable actions  necessary to obtain (and  will cooperate with  each
other  in obtaining)  any consent, authorization,  order or approval  of, or any
exemption by, any  governmental entity or  other public or  private third  party
required  to be obtained or  made by the Company, the  Purchaser or any of their
subsidiaries  in  connection  with  the  Offer,  the  Merger,  the  Stockholders
Agreement  or the taking of any action contemplated by any of the foregoing. The
Purchaser and the Company also have made certain agreements regarding access  to
information and holding in confidence information so furnished.

    NO  SOLICITATION.    From  the  date  of  the  Merger  Agreement  until  the
termination of  the  Merger  Agreement,  neither the  Company  nor  any  of  its
subsidiaries,  nor  any  of  their  respective  officers,  directors, employees,
representatives, agents  or affiliates,  will directly  or indirectly  initiate,
solicit   or  knowingly  encourage,  or  take  any  other  action  knowingly  to
facilitate, any inquiries or the making of any proposal that constitutes, or may
reasonably be expected to lead to,  an Acquisition Proposal (as defined  below),
or  enter into or maintain or continue  discussions or negotiate with any person
or entity in furtherance of such inquiries to obtain an Acquisition Proposal  or
agree  to or endorse an Acquisition Proposal,  or authorize or permit any of its
or their officers, directors or employees or any

                                       18
<PAGE>
of its  subsidiaries, or  any investment  banker, financial  advisor,  attorney,
accountant or other representative retained by it or any of its subsidiaries, to
take any such action; provided that, the Board is not prohibited from furnishing
information  to,  or entering  into,  maintaining or  continuing  discussions or
negotiations with, any  person or entity  that (i) made  inquiries or  proposals
prior  to the date of the Merger  Agreement regarding an Acquisition Proposal or
(ii) makes an unsolicited Acquisition Proposal, if the Board, after consultation
with and based  upon the advice  of independent  legal counsel (who  may be  the
Company's  regularly  engaged, independent  legal  counsel), determines  in good
faith that such action is necessary for  the Board to comply with its  fiduciary
duties  to Stockholders under applicable law,  and, prior to taking such action,
the Company (a) provides reasonable notice  to the Purchaser to the effect  that
it  is  taking such  action (unless  the  Board determines  in good  faith after
consultation with and based  upon the advice of  independent legal counsel  that
giving  such notice would breach the fiduciary duties of the Board in connection
with  an  Acquisition  Proposal  that   is  more  favorable  to  the   Company's
stockholders  than the  Offer and  the Merger  (a "Superior  Proposal")) and (b)
receives from such  person or  entity an executed  confidentiality agreement  in
reasonably  customary form. The  term "Acquisition Proposal"  means any inquiry,
offer or proposal regarding any of  the following (other than transactions  with
the  Purchaser or  the Sub contemplated  by the Merger  Agreement) involving the
Company or  any  of  its  subsidiaries: (i)  any  merger,  consolidation,  share
exchange,  recapitalization, business combination  or other similar transaction;
(ii) any sale, lease, exchange, mortgage, pledge, transfer or other  disposition
of  all or substantially all  of the assets of  the Company and its subsidiaries
taken as a whole, in a single  transaction or a series of related  transactions;
(iii)  any tender  offer or exchange  offer for  20% or more  of the outstanding
shares of capital stock of the Company or the filing of a registration statement
under the Securities  Act of  1933 in connection  with that  tender or  exchange
offer;  or (iv) any public  announcement of a proposal,  plan or intention to do
any of the foregoing or any agreement to engage in any of the foregoing.

    Pursuant to the Merger Agreement, the Board will not (i) withdraw or modify,
or propose to withdraw or  modify, in a manner adverse  to the Purchaser or  the
Sub,  its approval or recommendation  of the Offer, the  Merger Agreement or the
Merger, (ii)  approve or  recommend, or  propose to  approve or  recommend,  any
Acquisition Proposal or (iii) cause the Company to enter into any agreement with
respect to any Acquisition Proposal, unless, prior to the time of acceptance for
payment  of  Shares in  the Offer,  the  Board determines  in good  faith, after
consultation with and based upon the  advice of independent legal counsel,  that
it  is necessary to  do so in order  to comply with its  fiduciary duties to the
Stockholders under applicable  law, in  which event  the Board  may withdraw  or
modify its approval or recommendation of the Offer, the Merger Agreement and the
Merger,  approve or recommend a Superior Proposal  or cause the Company to enter
into an agreement with respect to a Superior Proposal. The Company will  provide
reasonable  notice to the Purchaser  or the Sub to the  effect that it is taking
such action.

    FEES AND  EXPENSES.   The  Merger  Agreement  provides that  all  costs  and
expenses  incurred in connection with the  Merger Agreement and the transactions
contemplated by the  Merger Agreement will  be paid by  the party incurring  the
expenses.  In addition, in the event that  an Acquisition Proposal has been made
to or recommended or accepted by the Company, and either (i) the Purchaser shall
have terminated the Merger Agreement as a result of the Board having  withdrawn,
modified  or changed its  recommendation or approval of  the Merger Agreement or
the Offer in a manner adverse to  the Purchaser or the Board having approved  or
recommended  any Acquisition Proposal or (ii)  the Company shall have terminated
the Merger  Agreement in  order to  enter into  an agreement  in respect  of  an
Acquisition  Proposal, the  Company has  agreed to  pay the  Purchaser a  fee in
immediately available funds equal to $6,000,000.

    CONDITIONS TO THE MERGER.  Pursuant to the Merger Agreement, the  obligation
of  each party to effect the Merger is subject to the satisfaction, prior to the
proposed Effective Time, of the  following conditions: (i) the Merger  Agreement
and  the Merger shall have been approved  and adopted by the affirmative vote of
the holders of a majority of the Shares entitled to vote, if a vote is  required
by  applicable law, (ii) all necessary  waiting periods applicable to the Merger
under the HSR Act shall have

                                       19
<PAGE>
been terminated or  shall have  expired, (iii) no  temporary restraining  order,
preliminary  or  permanent injunction  or  other order  issued  by any  court or
governmental authority or  other legal  restraint or  prohibition preventing  or
restricting  the consummation  of the  Merger shall  be in  effect and  (iv) the
Purchaser shall have accepted for payment  and paid for the Shares tendered  and
not withdrawn pursuant to the Offer, provided that this condition will be deemed
satisfied with respect to the Purchaser and the Sub, if the Purchaser shall have
failed  to purchase Shares in violation of  the Merger Agreement or the terms of
the Offer.

    TERMINATION.   The  Merger  Agreement  may  be  terminated  and  the  Merger
abandoned  at any  time prior  to the  Effective Time,  whether before  or after
approval by the  Stockholders of the  matters presented in  connection with  the
Merger  (i) by mutual written consent of the Board and the board of directors of
the Purchaser; (ii)  by either  the Company or  the Purchaser,  if, without  any
material  breach by  the terminating party  of its obligations  under the Merger
Agreement, the purchase of Shares pursuant to the Offer shall not have  occurred
on  or before November 30,  1995; (iii) by the Company  or the Purchaser, if the
Offer expires or is  terminated or withdrawn pursuant  to its terms without  any
Shares  being purchased in  accordance with the  Merger Agreement, provided that
the Purchaser  may not  so terminate  the Merger  Agreement if  the  Purchaser's
termination  of, or  the failure  to accept  for payment  or pay  for any Shares
tendered pursuant to, the Offer does not follow the failure to occur, of any  of
the  conditions to the  Offer or is otherwise  in violation of  the terms of the
Offer or the  Merger Agreement; (iv)  by the  Company or the  Purchaser, if  any
court  of  competent  jurisdiction shall  have  issued  an order  (other  than a
temporary restraining  order),  decree  or  ruling or  taken  any  other  action
restraining,  enjoining or otherwise prohibiting the purchase of Shares pursuant
to the Offer or  the Merger, provided  that such right  to terminate the  Merger
Agreement  under this clause  is not available  to any party  who shall not have
used its reasonable best efforts, subject to the terms of the Merger  Agreement,
to remove or lift such order, decree or ruling; (v) by the Company, if the Offer
has  not  been timely  commenced  in accordance  with  the terms  of  the Merger
Agreement; (vi) by  the Purchaser, if  the Board shall  (a) withdraw, modify  or
change  its recommendation or approval in respect of the Merger Agreement or the
Offer in a manner adverse to the  Purchaser or (b) have approved or  recommended
any proposal other than by the Purchaser or the Sub in respect of an Acquisition
Proposal; (vii) subject to the terms of the Merger Agreement, by the Company, to
allow  the  Company to  enter into  an  agreement in  respect of  an Acquisition
Proposal; and (viii) prior to the consummation of the Offer, by the Company,  if
any  of the  representations or warranties  of the  Purchaser or the  Sub in the
Merger Agreement were untrue or incorrect  in any material respect when made  or
have since become, and at the time of termination remain, untrue or incorrect in
any  material respect, or the Purchaser or the Sub shall have breached or failed
to comply in any material respect with  any of its obligations under the  Merger
Agreement,  or any other  events or circumstances have  occurred that render the
conditions to  the Company's  obligation to  effect the  Merger not  able to  be
satisfied  on or before  November 30, 1995.  In the event  of termination of the
Merger Agreement  by either  the Company  or the  Purchaser as  provided in  the
Merger  Agreement, the Merger  Agreement will become  void and there  will be no
liability or obligation on the part of the Purchaser, the Sub or the Company, or
their respective officers, directors or shareholders, except as provided in  the
Merger  Agreement.  In addition,  following the  Control  Date if  the Purchaser
acquires in the Offer at least a majority of the outstanding Shares  (calculated
on a fully diluted basis), and prior to the Effective Time, and as long as there
is  at  least  one  Continuing  Director, if  requested  by  a  majority  of the
Continuing Directors, all other directors will abstain from acting upon, and the
approval of  a  majority  of  the  Continuing  Directors  will  be  required  to
authorize,  any amendment or termination of the Merger Agreement by the Company,
any extension for the performance or waiver of the obligations or other acts  of
the Purchaser or the Sub and any waiver of the Company's rights under the Merger
Agreement.

    INDEMNIFICATION.   The Purchaser and the Sub  have agreed that all rights to
indemnification  and  exculpation  now  existing  in  favor  of  the  directors,
officers,  employees and  agents of  the Company as  provided in  its charter or
by-laws or otherwise  in effect  as of  the date  of the  Merger Agreement  with
respect to matters occurring prior to the Effective Time will survive the Merger
and continue in full

                                       20
<PAGE>
force  and  effect.  The  Merger  Agreement  provides  that  the  Purchaser will
indemnify, defend and hold harmless, to  the full extent permitted by law,  each
present  or former officer, director, employee or agent of the Company or any of
its  subsidiaries  (the  "Indemnified  Parties")  against  all  losses,  claims,
damages,   costs,  liabilities  or  judgements  or  amounts  that  are  paid  in
settlement, including  advancement of  expenses (including  attorneys' fees)  as
incurred  in respect of  any threatened, pending  or contemplated claim, action,
suit or proceeding,  whether criminal, civil,  administrative or  investigative,
including, without limitation, any action by or on behalf of any or all security
holders  of the Company  or by or in  the right of the  Company or the Surviving
Corporation, or  investigation  relating  to  any action  or  omission  by  such
Indemnified  Party  in its  capacity  as such  (including  service to  any other
entity, plan, trust or the like at the Company's request) occurring on or  prior
to   the   Effective  Time   ("Indemnified  Liabilities"),   including,  without
limitation, any  Indemnified Liabilities  that arise  out of  or relate  to  the
transactions contemplated by the Merger Agreement).

    For  a  period of  no fewer  than six  years after  the Effective  Time, the
Purchaser will  cause  to  be  maintained in  effect  the  current  policies  of
directors'  and officers' liability insurance maintained  by the Company and its
subsidiaries (provided that  the Surviving Corporation  may substitute  policies
with  reputable and financially sound carriers of at least the same coverage and
containing terms and conditions  no less advantageous,  as long as  substitution
does  not result in gaps or lapses  in coverage) with respect to matters arising
before the Effective Time, provided that  the Purchaser will not be required  to
pay  an annual premium for  such insurance in excess of  200% of the last annual
premium paid by the Company  prior to the date of  the Merger Agreement, but  in
that  case  will purchase  as much  coverage  as possible  for such  amount. The
Purchaser will cause the  Surviving Corporation to  pay all expenses  (including
reasonable  attorneys'  fees) reasonably  incurred  by an  Indemnified  Party in
successfully enforcing the  rights to  which the Indemnified  Party is  entitled
under  the Merger Agreement,  the Surviving Corporation's  by-laws or otherwise.
Should the Surviving Corporation fail to comply with the foregoing  obligations,
the Purchaser will be responsible for those obligations.

    AMENDMENT.   To the extent permitted by applicable law, the Merger Agreement
may be amended,  by action by  or on behalf  of the Boards  of Directors of  the
Company, the Purchaser and the Sub; provided that, after the Merger Agreement is
approved  by  the Stockholders,  no amendment  will be  made that  decreases the
amount of consideration to be delivered to the Stockholders or adversely affects
the rights of the Stockholders under the Merger Agreement, without the  approval
of  the Stockholders. In addition, following  the Control Date (if the Purchaser
acquires in the Offer at least a majority of the outstanding Shares  (calculated
on  a fully diluted  basis)) and prior  to the Effective  Time, any amendment or
termination of the Merger Agreement, extension for the performance or waiver  of
the  obligations or  other acts  of the Purchaser  or the  Sub or  waiver of the
Company's rights under the Merger Agreement,  will require the concurrence of  a
majority of the Continuing Directors.

    TIMING.   The exact timing and details for the Merger will depend upon legal
requirements and a  variety of  other factors,  including the  number of  Shares
acquired  by the  Purchaser pursuant  to the  Offer. Although  the Purchaser has
agreed to cause the Merger to be consummated on the terms set forth above, there
can be no assurance as to the timing of the Merger.

    DELAWARE LAW.    The  Board  has  approved  the  Merger  Agreement  and  the
transactions  contemplated  by  it,  including the  Offer,  the  Merger  and the
Stockholders Agreement, and  the entry  by the Purchaser  into the  Stockholders
Agreement for purposes of Section 203 of the DGCL. Accordingly, the restrictions
of  Section 203 do not apply to  the transactions contemplated by the Offer, the
Merger Agreement or the Stockholders Agreement. Section 203 of the DGCL prevents
an "interested stockholder" (generally,  a stockholder owning 15%  or more of  a
corporation's  outstanding voting  stock or  an affiliate  or associate  of that
stockholder) from engaging  in a  "business combination" (defined  to include  a
merger  and certain other transactions) with a Delaware corporation for a period
of three years following the date on which the stockholder became an  interested
stockholder, unless (i) prior to that date, the corporation's board of directors
approved either the business combination or the transaction that resulted in the
stockholder  becoming an interested  stockholder, (ii) upon  consummation of the
transaction that resulted in the stockholder becoming an interested stockholder,
the

                                       21
<PAGE>
interested stockholder  owned at  least 85%  of the  corporation's voting  stock
outstanding  at the  time the transaction  commenced (excluding  shares owned by
certain employee stock plans and persons who are directors and also officers  of
the  corporation)  or  (iii)  on  or  subsequent  to  that  date,  the  business
combination is approved by the  corporation's board of directors and  authorized
at  an annual or special meeting of stockholders, and not by written consent, by
the affirmative vote of  at least 66  2/3% of the  outstanding voting stock  not
owned by the interested stockholder. As described above, Section 203 of the DGCL
does not apply to the Offer, the Merger or the Stockholders Agreement.

THE STOCKHOLDERS AGREEMENT

    The  following  is  a summary  of  the  material terms  of  the Stockholders
Agreement. This  summary  is  not  a  complete  description  of  the  terms  and
conditions  of the  Stockholders Agreement and  is qualified in  its entirety by
reference to the full text of the Stockholders Agreement, which is  incorporated
by  reference and  a copy  of which  has been  filed with  the Commission  as an
exhibit to the Schedule 14D-1. The  Stockholders Agreement may be examined,  and
copies may be obtained, as set forth in Section 8 above.

    TENDER  OF  SHARES.    Simultaneously  with  the  execution  of  the  Merger
Agreement, the Purchaser, the Sub and  each of the Selling Stockholders  entered
into the Stockholders Agreement. Upon the terms and subject to the conditions of
that agreement, the Selling Stockholders have severally agreed validly to tender
and  not to withdraw pursuant to and in  accordance with the terms of the Offer,
not later  than the  tenth business  day  after commencement  of the  Offer,  an
aggregate   of  2,871,132  Shares  owned   beneficially  by  them.  The  Selling
Stockholders will have  no obligation to  tender the Founders  Shares after  the
earliest  of (i) the  termination, expiration, abandonment  or withdrawal or the
Offer, (ii) December 30, 1995 and (iii) the termination of the Merger  Agreement
under  any of the circumstances described in  clause (i), (ii), (iii), (iv), (v)
or (viii) under "The Merger Agreement -- Termination" above.

    STOCK OPTION.  Each of the Selling Stockholders has granted the Purchaser an
irrevocable option (collectively,  the "Stock  Options") to  purchase all  their
Shares  (less 100,000 Shares  beneficially owned by  each of Mr.  Samson and Ms.
Varis) at a purchase price per Share  equal to the Offer Price. Pursuant to  the
Stockholders  Agreement, if (i) the Offer  is terminated, abandoned or withdrawn
by the Purchaser due  to any of  the following: (a) the  failure to achieve  the
Minimum  Tender Condition, (b) the representations and warranties of the Company
in the Merger Agreement  were untrue or incorrect  in any material respect  when
made  or (except for those that address matters as of a specific date and except
for changes specifically permitted under the Merger Agreement) thereafter become
and remain untrue or incorrect in any material respect, (c) the Company breaches
or fails to comply in any material respect with any of its obligations under the
Merger Agreement  and,  with  respect to  any  breach  or failure  that  can  be
remedied,  the breach or failure  is not remedied within  10 business days after
the Purchaser has furnished the Company written notice of the breach or failure,
(d) the Board withdraws or materially modifies or changes its recommendation  of
the  Offer,  the  Merger Agreement  or  the  Merger, or  the  Board  approves or
recommends an  Acquisition Proposal  or (e)  a court  of competent  jurisdiction
issues  an  order,  decree or  ruling  or  takes any  other  action restraining,
enjoining or otherwise prohibiting the Purchase of Shares pursuant to the  Offer
or  the Merger as a result  of a suit, action or  proceeding by a party that has
made an Acquisition Proposal; or (ii) the Offer is consummated but the Purchaser
has not  accepted  for  payment  and  paid for  the  Founders  Shares,  and  the
non-acceptance  or non-payment is not in contravention of the Purchaser's or the
Sub's obligations under  the Merger Agreement  or the Offer,  the Stock  Options
will  become exercisable, in whole  but not in part, upon  the first to occur of
any such event and continuing until 30 days after the date of the occurrence  of
that  event, as long as: (i) all waiting  periods under the HSR Act required for
the purchase of the Option Shares upon such exercise shall have expired or  been
waived,  and (ii)  there shall not  be in  effect any injunction  or other order
issued by  any court  or governmental,  administrative or  regulatory agency  or
authority  prohibiting  the  exercise  of  the  Stock  Options  pursuant  to the
Stockholders Agreement. In the event that  the Purchaser elects to exercise  the
Stock Options, the

                                       22
<PAGE>
Purchaser must send a written notice to the Selling Stockholders identifying the
place  and date (not fewer than two or  more than 10 business days from the date
of that notice) for the closing of the purchase.

    Under the Stockholders Agreement, if the Purchaser purchases Shares pursuant
to the Stock Options, it is required, subject to certain conditions, to offer to
purchase all the other outstanding Shares within  30 days on the same terms.  In
addition,  if,  at  any time  within  183  days after  the  consummation  of the
purchase, the Purchaser or any of  its affiliates sells, exchanges or  otherwise
disposes  of any of  those Shares, voluntarily  or otherwise (including, without
limitation, pursuant  to  a merger),  and  if the  cash  or fair  value  of  the
consideration per Share received in exchange exceeds the purchase price of those
Shares,  then the Purchaser is required promptly  to pay or deliver an aggregate
of 60%  of  that excess  to  the respective  Selling  Stockholders pro  rata  in
relation to the number of Shares sold by them pursuant to the Stock Options.

    VOTING.   Each Selling Stockholder has agreed that, until the first to occur
of December 30, 1995 or termination  of the Merger Agreement in accordance  with
its  terms, at any meeting of the Stockholders or in connection with any written
consent of the Stockholders, that Selling Stockholder will vote (or cause to  be
voted)  the Shares held  of record or beneficially  by that Selling Stockholder,
(i) in favor of  the Merger, the  execution and delivery by  the Company of  the
Merger  Agreement and the  approval of the  terms of the  Merger Agreement; (ii)
against any action or agreement that would result in a breach in any respect  of
any  agreement of the Company under the  Merger Agreement; and (iii) against any
other action  that could  reasonably be  expected to  interfere with,  delay  or
otherwise  adversely affect the Merger and  the transactions contemplated by the
Merger Agreement. Each  Selling Stockholder's obligations  regarding voting,  as
well  as that Selling Stockholder's obligation  to waive any rights of appraisal
or rights to dissent  from the Merger, terminate  following any decrease in,  or
change  in the form of, the consideration payable to Stockholders in the Merger,
unless that Selling Stockholder gives its consent to the decrease or change.

    NO SOLICITATION.   The  Selling  Stockholders have  further agreed  not  to,
directly  or indirectly, initiate, solicit  or knowingly encourage (including by
way of  furnishing non-public  information  or assistance),  or take  any  other
action knowingly to facilitate, any inquiries or the making of any proposal that
constitutes,  or reasonably may be expected to lead to, an Acquisition Proposal,
enter into or maintain or continue  discussions or negotiate with any person  or
entity  in furtherance of  such inquiries or to  obtain an Acquisition Proposal,
agree to or endorse an Acquisition Proposal or authorize or permit any person or
entity acting on behalf of that Selling Stockholder to do any of the  foregoing.
Under  the  Stockholders  Agreement,  if any  Selling  Stockholder  receives any
inquiry or proposal regarding any Acquisition Proposal, that Selling Stockholder
is required promptly to  inform the Purchaser of  that inquiry or proposal.  The
Purchaser's  exclusive remedy for a breach  of these provisions is an injunction
or decree of specific performance, and not monetary damages.

    REPRESENTATIONS, WARRANTIES, COVENANTS AND OTHER AGREEMENTS.  In  connection
with  the  Stockholders Agreement,  the Selling  Stockholders have  made certain
customary representations, warranties and  covenants, including with respect  to
(i)  their ownership of the Founders Shares,  (ii) their authority to enter into
and perform  their  obligations  under the  Stockholders  Agreement,  (iii)  the
receipt  of requisite governmental  consents and approvals,  (iv) the absence of
liens  and  encumbrances  on  and  in  respect  of  the  Founders  Shares,   (v)
restrictions  on the transfer  of the Founders Shares,  (vi) the solicitation of
Acquisition Proposals and (vii) the waiver of their appraisal rights.

THE EMPLOYMENT AGREEMENT

    Simultaneously with the execution of  the Merger Agreement, the Company  and
Marvin   S.  Samson  entered  into  an  employment  agreement  (the  "Employment
Agreement"). Beginning on the Control Date,  the Company has agreed to  continue
to  employ Mr. Samson as president,  chief executive officer and chief operating
officer of the Company, and the Purchaser has agreed to employ Mr. Samson as  an
executive vice president of the Purchaser. The Employment Agreement provides for
an  annual salary of not less than $400,000 per year plus any other compensation
as may, from time to

                                       23
<PAGE>
time, be determined by the Company. In addition, Mr. Samson will participate  in
certain  benefit Plans (as  defined in the Employment  Agreement) of the Company
or, at the  option of Mr.  Samson and on  a basis reasonably  acceptable to  the
Company and the Purchaser, of the Purchaser.

    The  Employment Agreement  expires on the  fifth anniversary  of the Control
Date, but will be automatically renewed  for one-year periods, unless notice  of
termination  is given by either  party. In addition, the  Company may retain Mr.
Samson as a consultant  for a one-year period  following the termination of  his
employment.  During that period, the Company will pay Mr. Samson an amount equal
to his  base salary  immediately prior  to the  termination of  employment.  The
Employment  Agreement provides for a severance payment of not less than $400,000
per year  plus  certain  benefits  during the  initial  five-year  term  of  the
Employment  Agreement  (the  "Initial Term"),  in  the event  that  Mr. Samson's
employment is terminated without cause.  The Employment Agreement also  provides
for a severance payment of not less than $200,000 per year plus certain benefits
during the Initial Term, in the event that Mr. Samson voluntarily terminates his
employment.

    During  Mr. Samson's  employment under  the Employment  Agreement, except as
otherwise consented to or approved by Mr. Samson and the Purchaser, (i) (a)  the
Board  will be comprised of seven members, three to be designated by Mr. Samson,
three to be designated by the Purchaser (the "SPI directors") and one, who  will
be  an employee of  Bayer Corporation or  any of its  affiliates (other than the
Purchaser and its subsidiaries), to be  designated by the Purchaser, subject  to
the  approval by  Mr. Samson, which  approval will not  be unreasonably withheld
(the "Bayer director"), (b) the consent or  approval of at least one of the  SPI
directors  will  be  required  prior to  the  Company  taking  any extraordinary
corporate actions, including financings, purchases or sales of assets not in the
ordinary course of  business, issuances of  securities, providing  compensation,
perquisites  or benefits  beyond levels  customary in  the multisource industry,
actions  with  respect   to  the  certificate   of  incorporation  or   by-laws,
reorganizations,  recapitalizations  and business  combinations,  encumbering of
assets and actions that  could result in a  violation of agreements relating  to
indebtedness of the Purchaser or (with the additional consent or approval of the
Bayer  director) agreements between the Purchaser (or any of its affiliates) and
Bayer Corporation (or any  of its affiliates), and  (c) after consultation  with
the  other  directors,  the SPI  directors  will  be entitled  to  authorize and
approve, as actions of  the Board, corporate actions  not inconsistent with  the
provisions  of  the  Employment Agreement,  including  financings,  issuances of
securities and encumbering of assets;  (ii) Mr. Samson will  be in the slate  of
the Purchaser's management nominees for re-election as a director; (iii) neither
the Company's name nor its logo will be modified in any way, and the Company may
continue  to use its name  and logo on product labelling  and the like; (iv) the
headquarters of the  Company will  remain in Cherry  Hill, New  Jersey; (v)  the
Company will not be required to sell products to or manufacture products for the
Purchaser  or any  affiliate of  the Purchaser  on terms  less favorable  to the
Company than those the  Company provides to  unaffiliated customers for  similar
purchase  quantities; and (vi) the Company will  have funds made available to it
to the extent of Available Cash (as defined in the Employment Agreement).

    The Employment Agreement provides that Mr.  Samson will not use or  disclose
at  any time during or after his employment with the Company any trade secret or
proprietary or confidential information of the Company or any of its affiliates.
During Mr. Samson's employment with the Company, during the advisory period,  if
any,  during any period in which the Company is making severance payments to Mr.
Samson, and, in the  event of termination  for cause, until  the earlier of  the
sixth  anniversary  of  the Control  Date  and  the fourth  anniversary  of such
termination, Mr. Samson will not be engaged as an officer, director or  employee
of,  or in any way be associated in a management or ownership capacity with, any
corporation, partnership or other enterprise or venture that conducts a business
in competition  with the  business of  the  Company or  the Purchaser  or  their
subsidiaries  at the time  of such termination or  expiration; provided that Mr.
Samson may own not more than three percent of the outstanding securities of  any
publicly-held company.

    The  Purchaser has  agreed to cause  the Company to  perform its obligations
under the Employment Agreement after the Control Date.

                                       24
<PAGE>
    The Employment  Agreement  provides  that  a  compensation  agreement  dated
October  19, 1991 (the "Compensation Continuation Agreement") and a split dollar
insurance agreement dated  March 25,  1991 (the "Split  Dollar Agreement")  will
continue  in effect  in accordance with  their terms, unless  surrendered by Mr.
Samson. The  Compensation Continuation  Agreement provides  for payment  to  Mr.
Samson  or his designee, for one  year after Mr. Samson's retirement, disability
or death,  a sum  equal  to his  annual base  salary  immediately prior  to  his
retirement, disability or death, as the case may be, and thereafter for a period
of  nine  years  annual  payments  of 50%  of  that  amount.  Payment  under the
Compensation Continuation Agreement  depends upon Mr.  Samson's compliance  with
certain  covenants, including  a covenant  against competition.  Pursuant to the
Split Dollar Agreement, a trust created  by Mr. Samson purchased a split  dollar
life  insurance  policy on  the lives  of Mr.  Samson and  his wife.  The policy
provides  for  death  benefits  aggregating   $5,000,000  to  be  paid  to   the
beneficiaries of Mr. Samson's trust. The Company pays the annual premiums on the
policy,  minus a sum  equal to the lesser  of the cost  of a comparable one-year
term life insurance policy or the applicable one-year term premium cost computed
under the Internal Revenue  Service's Revenue Ruling 55-747.  The Company has  a
security  interest in the policy's death benefit equal to the sum of all premium
payments made by the Company.

BOLAR AGREEMENT

    Pursuant to an agreement dated as of December 31, 1985 among Marvin  Samson,
Agvar   Chemicals  Inc.   (whose  sole   shareholder  is   Agnes  Varis),  Bolar
Pharmaceutical Co., Inc. ("Bolar") and the Company (the "Bolar Agreement"),  the
Company was granted a right of first refusal to purchase from any other party to
the  agreement all Shares for which such  party received a bona fide third-party
offer, for the same consideration as in the third-party offer. The other parties
to the agreement were also granted an  option, exercisable on a pro rata  basis,
to  purchase  such Shares,  to the  extent  the Company  failed to  exercise its
option. Pursuant to a letter agreement dated  July 28, 1995, the parties to  the
Bolar Agreement, including Circa Pharmaceuticals, the successor to Bolar, waived
any  rights they may have  had under the Bolar  Agreement in connection with the
Offer, the Merger and the Stockholders Agreement. The Bolar Agreement expires in
accordance with its terms on December 31, 1995.

OTHER MATTERS

    APPRAISAL RIGHTS.   No  appraisal rights  are available  to Stockholders  in
connection  with the Offer. However, if the Merger is consummated, a Stockholder
will have certain rights  under Section 262  of the DGCL  to dissent and  demand
appraisal  of, and  payment in  cash for the  fair value  of, that Stockholder's
Shares. Those rights, if the statutory procedures are complied with, could  lead
to  a judicial determination of the fair value (excluding any value arising from
the Merger) required  to be paid  in cash to  dissenting Stockholders for  their
Shares.  Any judicial determination of  the fair value of  Shares could be based
upon considerations other than or in addition to the Offer Price and the  market
value  of the  Shares, including  asset values and  the investment  value of the
Shares. The value so determined  could be more or less  than the Offer Price  or
the Merger Consideration.

    If  a Stockholder who demands appraisal under  Section 262 of the DGCL fails
to perfect,  or effectively  withdraws  or loses,  his  right to  appraisal,  as
provided  in the DGCL, the Shares of that Stockholder will be converted into the
Merger Consideration in accordance with the Merger Agreement. A Stockholder  may
withdraw  his  demand for  appraisal by  delivering to  the Purchaser  a written
withdrawal of such demand for appraisal and acceptance of the Merger.

    Failure to  follow  the  steps required  by  Section  262 of  the  DGCL  for
perfecting appraisal rights may result in the loss of those rights.

    GOING PRIVATE TRANSACTIONS.  Rule 13e-3 under the Exchange Act is applicable
to  certain "going-private"  transactions. The  Purchaser does  not believe that
Rule 13e-3 will  be applicable to  the Merger, unless,  among other things,  the
Merger  is  completed more  than one  year  after termination  of the  Offer. If
applicable, Rule 13e-3 would require, among other things, that certain financial
information

                                       25
<PAGE>
regarding the  Company and  certain information  regarding the  fairness of  the
Merger  and the consideration offered to minority Stockholders be filed with the
Commission and disclosed to minority  Stockholders prior to consummation of  the
Merger.

13.  DIVIDENDS AND DISTRIBUTIONS

    If,  on or after  the date of  the Merger Agreement,  the Company should (i)
split, combine  or  otherwise change  the  Shares or  its  capitalization,  (ii)
acquire  currently  outstanding Shares  or otherwise  cause  a reduction  in the
number of outstanding Shares or (iii) issue or sell additional Shares, shares of
any other class  of capital  stock, other  voting securities  or any  securities
convertible  into, or rights, warrants or  options, conditional or otherwise, to
acquire, any of  the foregoing, then,  subject to the  provisions of Section  14
below,  the Purchaser, in its  sole discretion, may make  such adjustments as it
deems appropriate in the  Offer Price and other  terms of the Offer,  including,
without limitation, the number or type of securities offered to be purchased.

    If,  on or after the  date of the Merger  Agreement, the Company declares or
pays any cash dividend on the Shares, makes other distributions on the Shares or
issues with respect  to the Shares  any additional Shares,  shares of any  other
class  of capital stock,  other voting securities  or any securities convertible
into, or rights, warrants or options, conditional or otherwise, to acquire,  any
of  the foregoing, payable  or distributable to Stockholders  of record prior to
the transfer of the Shares purchased pursuant  to the Offer to the Purchaser  or
its nominee or transferee on the Company's stock transfer records, then, subject
to  Section 14  below, (i) the  Offer Price may,  in the sole  discretion of the
Purchaser, be reduced by  the amount of any  cash dividend or cash  distribution
and  (ii) the  whole of  any non-cash dividend,  distribution or  issuance to be
received by the  tendering Stockholders  will (a) be  received and  held by  the
tendering  Stockholders for the account of the Purchaser and will be required to
be promptly  remitted  and transferred  by  each tendering  Stockholder  to  the
Depositary  for  the  account  of  the  Purchaser,  accompanied  by  appropriate
documentation of transfer or (b) at the direction of the Purchaser, be exercised
for the  benefit  of the  Purchaser,  in which  case  the proceeds  of  exercise
promptly  will be remitted to the  Purchaser. Pending the remittance and subject
to applicable law, the Purchaser will  be entitled to all rights and  privileges
as  owner of any  non-cash dividend, distribution, issuance  or proceeds and may
withhold the entire Offer  Price or deduct  from the Offer  Price the amount  or
value   of  the  non-cash  dividend,  distribution,  issuance  or  proceeds,  as
determined by the Purchaser in its sole discretion.

    Pursuant to the  terms of the  Merger Agreement, the  Company is  prohibited
from  taking any of  the actions described  in the two  preceding paragraphs and
nothing in this Offer to Purchase shall constitute a waiver by the Purchaser  or
the  Sub of  any of  its rights under  the Merger  Agreement or  a limitation of
remedies available to  the Purchaser or  the Sub  for any breach  of the  Merger
Agreement, including termination of the Merger Agreement.

14.  CERTAIN CONDITIONS OF THE OFFER

    Notwithstanding any other provision of the Offer, the Purchaser shall not be
required  to  accept  for  payment  or,  subject  to  any  applicable  rules and

tendered,  and  may  postpone the  acceptance  for  payment or,  subject  to the

Company is then required  to issue pursuant to  obligations outstanding at  that
date  under employee stock option or other benefit plans or otherwise), (ii) any
applicable waiting periods under

    Purchaser  and its subsidiaries, taken as a  whole, or to compel the Company
    or the Purchaser to dispose of or hold separate any material portion of  the

    the  Purchaser and its  subsidiaries, taken as  a whole, as  a result of the
    Offer or any of the other transactions contemplated by the Merger Agreement,
    (3) seeking to impose material limitations  on the ability of the  Purchaser
    or  Sub to  acquire or hold,  or exercise  full rights of  ownership of, any

    limitation,  the right to vote such Shares on all matters properly presented
    to the Stockholders of the Company, or (4) seeking to prohibit the Purchaser
    or any  of its  subsidiaries from  effectively controlling  in any  material
    respect  any material portion  of the business or  operations of the Company
    and its subsidiaries;

        (B) any  governmental entity  or  federal or  state court  of  competent
    jurisdiction  shall have  enacted, issued, promulgated,  enforced or entered
    any statute, rule, regulation, executive order, decree, injunction or  other
    order  that  is in  effect and  that (1)  materially restricts,  prevents or
    prohibits consummation of the Offer, the Merger or any material  transaction
    contemplated by the Merger Agreement, (2) prohibits or limits materially the

    effectively full  rights  of ownership  of  any Shares,  including,  without
    limitation,  the right to vote any Shares acquired by the Purchaser pursuant
    to the  Offer  or  otherwise  on  all  matters  properly  presented  to  the

    or the Merger;

                                       27
<PAGE>
        (G)  (1) it  shall have been  publicly disclosed or  the Purchaser shall
    have otherwise  learned that,  except as  contemplated by  the  Stockholders
    Agreement,  any person  or "group"  (as defined  in Section  13(d)(3) of the
    Exchange Act), other than  the Purchaser or its  affiliates or any group  of
    which  any of  them is  a member,  shall have  acquired beneficial ownership
    (determined pursuant to Rule  13d-3 promulgated under  the Exchange Act)  of
    more than 25% of the Shares, through the acquisition of stock, the formation
    of  a group  or otherwise, or  shall have  been granted an  option, right or

    market in the United States, (2)  the declaration of any banking  moratorium
    or any suspension of payments in respect of banks or any limitation (whether
    or  not mandatory) by any governmental  entity on, or other event materially
    adversely affecting, the extension of credit by lending institutions in  the
    United  States or (3)  in the case of  any of the  foregoing existing at the
    time of the commencement of the Offer, a material acceleration or  worsening
    of the foregoing; or

        (I)  for each real property  owned or operated by  the Company or any of
    its subsidiaries located in the state  of New Jersey, the Company shall  not
    have complied with the obligations imposed by the New Jersey Industrial Site
    Recovery  Act by: (1) securing and providing a copy to the Purchaser and Sub
    of a letter of non-applicability, (2)  securing and providing a copy to  the
    Purchaser  and Sub  of a  written approval by  the New  Jersey Department of
    Environmental Protection (the "NJDEP")  of a negative declaration  submitted
    by  the Company, (3) securing and providing  a copy to the Purchaser and Sub
    of a  no further  action letter  from the  NJDEP, (4)  filing a  DE  MINIMUS
    Quantity Exemption Affidavit and providing the Purchaser and Sub with a copy
    evidencing  the filing, (5)  securing and providing a  copy to the Purchaser
    and Sub of  a letter of  authorization from  the NJDEP for  the transfer  of
    ownership  or (6)  securing written approval  by the NJDEP  of a Remediation
    Agreement and providing a copy to the Purchaser and Sub;

which, in the judgment of the Purchaser in any such case, and regardless of  the
circumstances  (including any  action or omission  by the Purchaser  or the Sub)
giving rise to  any such  condition, makes it  inadvisable to  proceed with  the
acceptance for payment or payment.

    The  foregoing conditions are for the sole benefit of the Purchaser, the Sub
and their affiliates and may be asserted by the Purchaser or the Sub  regardless
of  the circumstances (including, without limitation,  any action or inaction by
the Purchaser, the Sub  or any of  their affiliates) giving rise  to any of  the
conditions  or may be waived by  the Purchaser or the Sub,  in whole or in part,
from time to time in  its sole discretion, except  as otherwise provided in  the
Merger  Agreement.  The failure  by  the Purchaser  or the  Sub  at any  time to
exercise any of the foregoing rights will not be deemed a waiver of any of those
rights and each  of those  rights will  be deemed an  ongoing right  and may  be
asserted at any time and from time to time.

15.  CERTAIN LEGAL MATTERS

    Except  as  described in  this Section  15,  based on  a review  of publicly
available filings made  by the Company  with the Commission  and other  publicly
available  information  concerning  the  Company,  but  without  any independent
investigation, neither the  Purchaser nor  the Sub is  aware of  any license  or
regulatory permit that appears to be material to the business of the Company and
its  subsidiaries, taken  as a  whole, that might  be adversely  affected by the
Purchaser's acquisition of Shares as contemplated  in this Offer to Purchase  or
of  any approval  or other  action by any  governmental authority  that would be
required for  the  acquisition  or  ownership of  Shares  by  the  Purchaser  as
contemplated in this Offer to Purchase. Should any such approval or other action
be  required, the Purchaser and the Sub presently contemplate that such approval
or other action will be sought, except as described below under "State  Takeover
Laws."  While, except as  otherwise expressly described in  this Section 15, the
Purchaser does not presently  intend to delay the  acceptance for payment of  or

                                       28
<PAGE>
payment  for Shares tendered  pursuant to the  Offer pending the  outcome of any
such matter, there can be no assurance  that any such approval or other  action,
if needed, would be obtained or would be obtained without substantial conditions
or  that failure to obtain any such approval or other action might not result in
consequences adverse to  the Company's  business or  that certain  parts of  the
Company's  business might not have to be  disposed of if such approvals were not
obtained or other actions were not taken or in order to obtain any such approval
or other action. If certain  types of adverse action  are taken with respect  to
the  matters discussed below, the Purchaser  could decline to accept for payment
or pay for any Shares tendered. See  Section 14 above for certain conditions  to
the Offer.

    CERTAIN  LITIGATION RELATING TO THE OFFER.  On July 31, 1995, a class action
complaint was filed  in the  Delaware Chancery Court  on behalf  of all  persons
(other  than the defendants) who own  Shares against the Company, Marvin Samson,
Judith U. Arnoff,  Agnes Varis, Barry  Waxman, Allen Misher,  Gus Blass and  the
Purchaser.  In the suit,  entitled Harbor Finance Partners  v. Marvin Samson, et
al., Civil Action No. 14447, the plaintiff has alleged, among other things, that
the defendants have breached their fiduciary duties to holders of the Shares  by
entering into an agreement with the Purchaser and failing to attempt to maximize
shareholder  value. The suit seeks various  remedies, including an injunction to
prevent consummation of the transaction, and damages, costs and disbursements of
the action.

    STATE TAKEOVER LAWS.  A number  of states throughout the United States  have
enacted  takeover statutes that purport, in varying degrees, to be applicable to
attempts to acquire  securities of  corporations that are  incorporated or  have
assets,  stockholders, executive offices or places  of business in those states.
In EDGAR V. MITE  CORP., the Supreme  Court of the United  States held that  the
Illinois  Business Takeover Act, which involved  state securities laws that made
the takeover  of  certain corporations  more  difficult, imposed  a  substantial
burden  on interstate commerce and therefore  was unconstitutional. In CTS CORP.
V. DYNAMICS CORP. OF  AMERICA, however, the Supreme  Court of the United  States
held  that a state may,  as a matter of corporate  law and, in particular, those
laws concerning corporate  governance, constitutionally  disqualify a  potential
acquiror  from  voting on  the  affairs of  a  target corporation  without prior
approval of the remaining stockholders,  provided that the laws were  applicable
only under certain conditions.

    Section  203 of  the DGCL  limits the ability  of a  Delaware corporation to
engage in business combinations with  "interested stockholders" (defined as  any
beneficial  owner  of  15%  or  more of  the  outstanding  voting  stock  of the
corporation) unless, among  other things, the  corporation's board of  directors
has  given  its  prior  approval  of  either  the  business  combination  or the
transaction  which  resulted   in  the  stockholder   becoming  an   "interested
stockholder."  The  Company  has represented  in  the Merger  Agreement  that it
properly approved, among other things, the Offer and the Merger for purposes  of
Section 203 of the DGCL.

    Based   on   information  supplied   by  the   Company  and   the  Company's
representations in the Merger Agreement, the Purchaser does not believe that any
state takeover statutes apply to the Offer or the Merger. Neither the  Purchaser
nor  the  Sub  has  currently  complied  with  any  state  takeover  statute  or
regulation. The Purchaser reserves the  right to challenge the applicability  or
validity  of any state law purportedly applicable to the Offer or the Merger and
nothing in this Offer  to Purchase or  any action taken  in connection with  the
Offer  or the Merger  is intended as a  waiver of that right.  If it is asserted
that any state takeover statute is applicable to the Offer or the Merger and  an
appropriate  court  does not  determine that  it is  inapplicable or  invalid as
applied to the  Offer or the  Merger, the  Purchaser might be  required to  file
certain  information  with, or  to receive  approvals  from, the  relevant state
authorities, and the Purchaser might be unable to accept for payment or pay  for
Shares  tendered pursuant to the Offer, or  be delayed in consummating the Offer
or the Merger. In such  case, the Purchaser may not  be obligated to accept  for
payment or pay for any Shares tendered pursuant to the Offer.

                                       29

    ANTITRUST.  Under the provisions of the HSR Act applicable to the Offer, the
purchase  of Shares under the Offer  may be consummated following the expiration
of a 15-calendar-day waiting period following  the filing by the Purchaser of  a
Notification  and Report  Form with respect  to the Offer,  unless the Purchaser
receives a request for additional  information or documentary material from  the
Antitrust  Division or the FTC or unless early termination of the waiting period
is granted. The  Purchaser expects that  such filing  will be made  on or  about
August  4, 1995 and  such waiting period will  expire at 11:59  p.m. on or about
August 19,  1995. If,  within  the initial  15-day  waiting period,  either  the
Antitrust  Division or  the FTC  requests additional  information or documentary
material from the  Purchaser concerning the  Offer, the waiting  period will  be
extended  and would expire 11:59 P.M., New York City time, on the tenth calendar
day after the date of substantial compliance by the Purchaser with such request.
Only one extension of  the waiting period pursuant  to a request for  additional
information  is authorized by the HSR Act. Thereafter, the waiting period may be
extended only by court order or with the consent of the Purchaser. In  practice,
complying  with a request for additional information or documentary material can
take a significant amount of time. In addition, if the Antitrust Division or the
FTC raises substantive  issues in  connection with a  proposed transaction,  the
parties  frequently engage in negotiations with the relevant governmental agency
concerning possible means  of addressing  those issues  and may  agree to  delay
consummation of the transaction while the negotiations continue.

    The  FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as the Purchaser's proposed  acquisition
of  the Company. At any time before  or after the Purchaser's purchase of Shares
pursuant to the Offer, the Antitrust Division or the FTC could take such  action
under  the  antitrust laws  as it  deems  necessary or  desirable in  the public
interest, including seeking  to enjoin the  purchase of Shares  pursuant to  the
Offer  or the consummation  of the Merger  or seeking the  divestiture of Shares
acquired by  the Purchaser  or  the divestiture  of  substantial assets  of  the
Purchaser  or  its subsidiaries,  or the  Company  or its  subsidiaries. Private
parties may  also bring  legal action  under the  antitrust laws  under  certain
circumstances.  There  can be  no assurance  that  a challenge  to the  Offer on
antitrust grounds will  not be  made or,  if such a  challenge is  made, of  the
result of that challenge.

16.  FEES AND EXPENSES

    The  Purchaser  has  retained  Georgeson  &  Company  Inc.  to  act  as  the
Information Agent, and Chemical to act as the Depositary, in connection with the
Offer. The Information Agent and the Depositary each will receive reasonable and
customary  compensation  for  its  services,  will  be  reimbursed  for  certain
reasonable  out-of-pocket  expenses  and  will  be  indemnified  against certain
liabilities and expenses in connection therewith, including certain  liabilities
under the federal securities laws.

    Except  as  set  forth  above,  the  Purchaser  will  not  pay  any  fees or
commissions to any broker  or dealer or other  person for soliciting tenders  of
Shares  pursuant  to the  Offer. Brokers,  dealers,  commercial banks  and trust
companies will be reimbursed by the Purchaser for customary mailing and handling
expenses incurred  by  them  in  forwarding  the  offering  materials  to  their
customers.

17.  MISCELLANEOUS

    The  Offer is  not being made  to (nor will  tenders be accepted  from or on
behalf of) holders of Shares residing in any jurisdiction in which the making of
the Offer  or  the  acceptance thereof  would  not  be in  compliance  with  the
securities,  blue sky or other laws  of the jurisdiction. However, the Purchaser
may, in its discretion, take  such action as it may  deem necessary to make  the
Offer  in any  jurisdiction and extend  the Offer  to holders of  Shares in that
jurisdiction. In any jurisdiction where the  securities, blue sky or other  laws
require  the Offer to be made by a  licensed broker or dealer, the Offer will be
deemed to be made on behalf of  the Purchaser by one or more registered  brokers
or dealers that are licensed under the laws of the jurisdiction.

    The  Purchaser has filed with the  Commission the Schedule 14D-1 pursuant to
Rule 14d-1 under the Exchange Act containing certain additional information with
respect to the Offer. The Schedule

                                       30
<PAGE>
and any amendments  to the  Schedule, including  exhibits, may  be examined  and
copies may be obtained from the principal office of the Commission in the manner
set  forth in  Section 8 above  (except that they  will not be  available at the
regional offices of the Commission).

    NO  PERSON  HAS  BEEN  AUTHORIZED  TO  GIVE  ANY  INFORMATION  OR  MAKE  ANY
REPRESENTATION ON BEHALF OF THE PURCHASER NOT CONTAINED IN THE OFFER TO PURCHASE
OR  IN  THE LETTER  OF TRANSMITTAL  AND, IF  GIVEN OR  MADE, THE  INFORMATION OR
REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED.

                   NOTE: SIGNATURE(S) MUST BE PROVIDED BELOW
              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

    The undersigned hereby  tenders to Schein  Pharmaceutical, Inc., a  Delaware
corporation  (the "Purchaser"), the above-described shares of Common Stock, $.01
par value (the "Shares"), of Marsam Pharmaceuticals Inc., a Delaware corporation
(the "Company"), for $21.00 per Share, net to the seller in cash, upon the terms
and subject to the conditions set forth in the Offer to Purchase, dated July 28,
1995 (the "Offer to Purchase"), receipt of which is hereby acknowledged, and  in
this  Letter  of  Transmittal  (which  together  constitute  the  "Offer").  The
undersigned understands that  the Purchaser  reserves the right  to transfer  or
assign, in whole or from time to time in part, to one or more of its affiliates,
the  right to purchase all or any portion of the Shares tendered pursuant to the
Offer, but any such transfer or assignment will not relieve the Purchaser of its
obligations under the Offer or prejudice the rights of tendering holders of  the
Shares  ("Stockholders")  to receive  payment  for Shares  validly  tendered and
accepted for payment pursuant to the Offer.

    Subject to, and effective upon, acceptance  for payment of, or payment  for,
Shares tendered with this Letter of Transmittal in accordance with the terms and
subject  to the conditions of the Offer  (including, if the Offer is extended or
amended, the  terms or  conditions  of any  such  extension or  amendment),  the
undersigned  hereby sells, assigns and  transfers to, or upon  the order of, the
Purchaser all right, title  and interest in  and to all of  the Shares that  are
being tendered hereby and any and all other Shares or other securities issued or
issuable in respect of such Shares on or after August 4, 1995 (a "Distribution")
and  irrevocably constitutes  and appoints  the Depositary  the true  and lawful
agent and attorney-in-fact of the undersigned  with respect to such Shares  (and
any  Distributions), with  full power  of substitution  (such power  of attorney
being deemed  to be  an irrevocable  power  coupled with  an interest),  to  (i)
deliver Certificates evidencing such Shares (and any Distributions), or transfer
ownership of such Shares (and all Distributions) on the account books maintained
by  a  Book-Entry  Transfer  Facility  together,  in  any  such  case,  with all
accompanying evidences of transfer  and authenticity to, or  upon the order  of,
the  Purchaser, upon receipt  by the Depositary, as  the undersigned's agent, of
the purchase price with  respect to such Shares,  (ii) present such Shares  (and
any  Distributions) for transfer on  the books of the  Company and (iii) receive
all benefits and otherwise exercise all  rights of beneficial ownership of  such
Shares  (and any Distributions), all in accordance with the terms and subject to
the conditions of the Offer.

    The undersigned hereby irrevocably appoints  each designee of the  Purchaser
as  the attorney-in-fact and proxy  of the undersigned, each  with full power of
substitution, to the full extent of the undersigned's rights with respect to all
Shares tendered hereby and  accepted for payment and  paid for by the  Purchaser
(and  any Distributions), including  without limitation, the  right to vote such
Shares (and any Distributions) in such manner as each such attorney and proxy or
his substitute shall, in  his sole discretion, deem  proper. All such powers  of
attorney  and  proxies,  being deemed  to  be irrevocable,  shall  be considered
coupled with an interest in the Shares tendered with this Letter of Transmittal.
Such appointment  will be  effective when,  and  only to  the extent  that,  the
Purchaser accepts such Shares for payment. Upon such acceptance for payment, all
prior  powers of attorney and  proxies given by the  undersigned with respect to
such Shares (and any Distributions) will be revoked, without further action, and
no subsequent powers of attorneys and proxies may be given with respect  thereto
(and,  if given,  will be  deemed ineffective).  The designees  of the Purchaser
will, with  respect  to  the  Shares (and  any  Distributions)  for  which  such
appointment  is effective, be empowered to  exercise all voting and other rights
of the undersigned with respect to  such Shares (and any Distributions) as  they
in  their sole discretion  may deem proper. The  Purchaser reserves the absolute
right to  require that,  in order  for  Shares to  be deemed  validly  tendered,
immediately upon the acceptance for payment of such Shares, the Purchaser or its
designees  are able to exercise  full voting rights with  respect to such Shares
(and any Distributions).

    All authority  conferred  or  agreed  to be  conferred  in  this  Letter  of
Transmittal  shall be  binding upon  the successors,  assigns, heirs, executors,
administrators and legal  representatives of  the undersigned and  shall not  be
affected  by, and  shall survive,  the death  or incapacity  of the undersigned.
Except as stated in the Offer to Purchase, this tender is irrevocable.

    The undersigned hereby represents and warrants that the undersigned has full
power and authority  to tender, sell,  assign and transfer  the Shares  tendered
hereby  (and any Distributions) and that, when the same are accepted for payment
and paid for by the Purchaser,  the Purchaser will acquire good, marketable  and
unencumbered  title thereto, free and clear  of all liens, restrictions, charges
and encumbrances, and that  the Shares tendered  hereby (and any  Distributions)
will  not be subject to  any adverse claim. The  undersigned, upon request, will
execute and deliver  any additional documents  deemed by the  Depositary or  the
Purchaser  to be  necessary or  desirable to  complete the  sale, assignment and
transfer of Shares  tendered hereby  (and any Distributions).  In addition,  the
undersigned  shall promptly remit and transfer to the Depositary for the account
of the Purchaser any and all Distributions issued to the undersigned on or after
August 4,  1995  in  respect  of the  Shares  tendered  hereby,  accompanied  by
appropriate  documentation of transfer, and pending such remittance and transfer
or appropriate assurance thereof, the Purchaser shall be entitled to all  rights
and  privileges as owner of  any such Distributions and  may withhold the entire
purchase price or deduct from the purchase price the amount of value thereof, as
determined by the Purchaser in its sole discretion.

    The undersigned understands that the valid tender of Shares pursuant to  any
one of the procedures described in section 3 of the Offer to Purchase and in the
instructions  to this Letter of Transmittal  will constitute a binding agreement
between the undersigned and the Purchaser  with respect to such Shares upon  the
terms and subject to the conditions of the Offer.

    The  undersigned recognizes that,  under certain circumstances  set forth in
the Offer to Purchase, the Purchaser may  not be required to accept for  payment
any  of the Shares tendered  hereby or may accept for  payment fewer that all of
the Shares tendered hereby.

    Unless otherwise  indicated in  this Letter  of Transmittal  under  "Special
Payment  Instructions," please  issue the  check for  the purchase  price and/or
return any  Certificates evidencing  Shares  not tendered  or not  accepted  for
payment  in the name(s) of the registered holder(s) appearing under "Description
of Shares  Tendered."  Similarly,  unless  otherwise  indicated  under  "Special
Delivery  Instructions," please  mail the  check for  the purchase  price and/or
return any  Certificates evidencing  Shares  not tendered  or not  accepted  for
payment  (and accompanying documents, as appropriate)  to the address(es) of the
registered holder(s) appearing  under "Description of  Shares Tendered." In  the
event  that both  the "Special Payment  Instructions" and  the "Special Delivery
Instructions" are  completed, please  issue  the check  for the  purchase  price
and/or  return  any  such Certificates  evidencing  Shares not  tendered  or not
accepted for payment (and accompanying documents, as appropriate) in the name(s)
of, and deliver  such check  and/or return such  Certificates (and  accompanying
documents,  as  appropriate) to  the  person(s) so  indicated.  Unless otherwise
indicated in this Letter of Transmittal under "Special Payment Instructions," in
the case  of  a  book-entry  delivery  of  Shares,  please  credit  the  account
maintained  at the Book-Entry Transfer Facility  indicated above with respect to
any Shares  not  accepted  for  payment. The  undersigned  recognizes  that  the
Purchaser  has no obligation  pursuant to the  "Special Payment Instructions" to
transfer any Shares from the name of the registered holder if the Purchaser does
not accept for payment any of the Shares tendered hereby.

    This  method of delivery of Certificates, this Letter of Transmittal and any
other required  documents, is  at the  option  and sole  risk of  the  tendering
Stockholder  and the delivery will be deemed made only when actually received by

should be allowed to ensure timely delivery.

    No alternative, conditional or  contingent tenders will  be accepted and  no

Certificates delivered to the Depositary with this Letter of Transmittal are  to
be  tendered, fill in the number  of Shares which are to  be tendered in the box
entitled "Number of Shares Tendered." In  such cases, a new Certificate for  the

unless  otherwise provided in the box entitled "Special Payment Instructions" or
the box entitled "Special Delivery Instructions" on this Letter of  Transmittal,
as  soon as  practicable after  the Expiration  Date. All  Shares represented by

Certificates, it will be necessary to complete, sign and submit as many separate
Letters of Transmittal as there are different registrations of Certificates.

    If this Letter of Transmittal or any Certificates or instruments of transfer
are  signed by  a trustee, executor,  administrator, guardian, attorney-in-fact,
officer of a corporation or other person acting in a fiduciary or representative
capacity, that  person should  so  indicate when  signing, and  proper  evidence
satisfactory  to the  Purchaser of  that person's  authority to  so act  must be
submitted.

    If this Letter of Transmittal is  signed by the registered holder(s) of  the
Shares  listed  and  transmitted  hereby,  no  endorsements  of  Certificates or
separate instruments of transfer are required  unless payment is to be made,  or
Certificates  not tendered or not  purchased are to be  issued or returned, to a
person other than the  registered holder(s). Signatures  on the Certificates  or
instruments of transfer must be guaranteed by an Eligible Institution.

    If  this  Letter  of  Transmittal  is signed  by  a  person  other  than the
registered holder(s) of the  Shares evidenced by  the Certificate(s) listed  and
transmitted  hereby,  the  Certificate(s)  must be  endorsed  or  accompanied by
appropriate instruments  of  transfer, in  either  case signed  exactly  as  the
name(s)  of the registered holder(s) appear on the Certificate(s). Signatures on
the Certificate(s) or instruments of transfer must be guaranteed by an  Eligible
Instruction.

    6.    TRANSFER  TAXES.   Except  as set  forth  in this  Instruction  6, the
Purchaser will pay or cause  to be paid any transfer  taxes with respect to  the
transfer  and sale  of Shares  to it  or its  order pursuant  to the  Offer. If,
however,  payment  of  the  purchase  price  is  to  be  made  to,  or  (in  the
circumstances  permitted hereby) if Certificates for  Shares not tendered or not
purchased are  to be  registered  in the  name of,  any  person other  than  the
registered  holder(s), or if tendered Certificates are registered in the name of
any person other  than the  person(s) signing  this Letter  of Transmittal,  the
amount  of any  transfer taxes (whether  imposed on the  registered holder(s) or
such person) payable on account of the transfer to such person will be  deducted
from  the purchase  priced unless satisfactory  evidence of the  payment of such
taxes or exemption therefrom is submitted.

    Except as  provided in  this Instruction  6, it  will not  be necessary  for
transfer tax stamps to be affixed to the Certificate(s) listed in this Letter of
Transmittal.

    7.    SPECIAL  PAYMENT  AND  DELIVERY  INSTRUCTIONS.    If  a  check  and/or
Certificates for unpurchased Shares  are to be  issued in the  name of a  person
other  than the signer of this Letter of Transmittal or if a check is to be sent
and/ or Certificates are to be returned to someone other than the signer of this
Letter of  Transmittal  or  to an  address  other  than that  shown  above,  the
appropriate  boxes on  this Letter  of Transmittal  should be  completed. If any
tendered Shares are not purchased for any reason and the Shares are delivered by
Book-Entry Transfer  Facility,  the  Shares  will  be  credited  to  an  account
maintained at the appropriate Book-Entry Transfer Facility.

    8.   REQUESTS FOR  ASSISTANCE OR ADDITIONAL COPIES.   Questions and requests

    9.   WAIVER OF CONDITIONS.  The conditions of the Offer may be waived by the
Purchaser, in  whole or  in part,  at any  time or  from time  to time,  in  the
Purchaser's sole discretion.

    10.   BACKUP  WITHHOLDING TAX.   Each  tendering Stockholder  is required to
provide the Depositary with a correct Taxpayer Identification Number ("TIN")  on
Substitute  Form W-9, which is provided  under "Important Tax Information" below
and to  certify that  the  Stockholder is  not  subject to  backup  withholding.
Failure  to provide the information  on the Substitute Form  W-9 may subject the
tendering Stockholder  to  31% federal  income  tax backup  withholding  on  the
payment  of the purchase price for  the Shares. The tendering Stockholder should
indicate in the  box in Part  III of the  Substitute Form W-9  if the  tendering
Stockholder  has not been issued a  TIN and has applied for  a TIN or intends to
apply for a TIN in the near future. If the Stockholder has indicated in the  box
in  Part III that a TIN has been  applied for and the Depositary is not provided
with a TIN  by the  time of  payment, the Depositary  will withhold  31% of  all

                           IMPORTANT TAX INFORMATION

    Under federal  income  tax law,  a  Stockholder whose  tendered  Shares  are
accepted  for payment is required to provide the Depositary (as payor) with such
Stockholder's correct TIN on Substitute Form  W-9 below. If such Stockholder  is
an  individual,  the  TIN  is  his  social  security  number.  If  the tendering
Stockholder has not been issued  a TIN and has applied  for a TIN or intends  to
apply  for a TIN in  the near future, the Stockholder  should so indicate on the
Substitute Form W-9. See Instruction 10. If the Depositary is not provided  with
the  correct TIN, the Stockholder may be subject to a $50 penalty imposed by the
Internal Revenue Service. In addition, payments that are made to the Stockholder
with respect to Shares purchased pursuant to the Offer may be subject to  backup
federal income tax withholding.

    Certain  Stockholders (including, among others, all corporations and certain
foreign individuals) are not subject  to these backup withholding and  reporting
requirements.  In  order  for  a  foreign individual  to  qualify  as  an exempt
recipient, that Stockholder must submit  a statement, signed under penalties  of
perjury, attesting to that individual's exempt status. Forms for such statements
can   be  obtained  from  the  Depositary.   See  the  enclosed  Guidelines  for
Certificates of  Taxpayer  Identification  Number on  Substitute  Form  W-9  for
additional instructions.

    If backup withholding applies, the Depositary is required to withhold 31% of
any  payments made to  the Stockholder. Backup withholding  is not an additional
tax. Rather, the tax liability of persons subject to backup withholding will  be
reduced  by the amount of tax withheld. If withholding results in an overpayment
of taxes, a refund may be obtained from the Internal Revenue Service.

PURPOSE OF SUBSTITUTE FORM W-9

    To prevent backup federal income tax withholding with respect to payment  of
the  purchase price  for Shares purchased  pursuant to the  Offer, a Stockholder
must provide the Treasury with his correct TIN by completing the Substitute Form
W-9 below, certifying that  the TIN provided on  Substitute Form W-9 is  correct
(or that the Stockholder is awaiting a TIN) and that (1) the Stockholder has not
been  notified by  the Internal  Revenue Service  that he  is subject  to backup
withholding as a result of  failure to report all  interest or dividends or  (2)
the  Internal Revenue Service has notified the  Stockholder that he is no longer
subject to backup withholding.

WHAT NUMBER TO GIVE THE DEPOSITARY

    The Stockholder  is required  to  give the  Depositary the  social  security
number  or employer  identification number  of the  record holder  of the Shares
tendered hereby. If the Shares are registered  in more than one name or are  not
in   the  name  of  the  actual  owner,  consult  the  enclosed  Guidelines  for
Certification of  Taxpayer  Identification Number  on  Substitute Form  W-9  for
additional guidance on which number to report.

    York City time, on Friday, September 1, 1995, unless the Offer is extended.

        6.   The  board of directors  of the Company  has unanimously determined
    that each of the Offer and the Merger (as defined in the Offer to  Purchase)
    is  fair to, and in  the best interests of,  the Company's stockholders, has
    approved the Merger Agreement (as defined in the Offer to Purchase) and  the

    the Merger, and recommends that the Company's stockholders accept the  Offer
    and tender all their Shares pursuant to the Offer.

        7.  Notwithstanding any other provision of the Offer, payment for Shares
    accepted  for payment pursuant to  the Offer will in  all cases be made only

    signature  guarantees, and (c) any other documents required by the Letter of

forward  their  Certificates  or  other  required  documents  or  complete   the
procedures for book-entry transfer prior to the Expiration Date, a tender may be
effected  by following the guaranteed delivery procedures specified in Section 3
of the Offer to Purchase.

other  person for soliciting tenders of Shares pursuant to the Offer (other than
the Depositary and the Information Agent as described in the Offer to Purchase).

cause and not to willful neglect.

(2) CIVIL PENALTY  FOR FALSE  INFORMATION WITH RESPECT  TO WITHHOLDING.--If  you
make  a  false statement  with no  reasonable  basis that  results in  no backup
withholding, you are subject to a $500 penalty.

(3)  CRIMINAL   PENALTY   FOR  FALSIFYING   INFORMATION.--Willfully   falsifying
certifications  or affirmations may subject  you to criminal penalties including
fines and/or imprisonment.

the "Offer").

--------------------------------------------------------------------------------
         THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT,
       NEW YORK CITY TIME, ON FRIDAY, SEPTEMBER 1, 1995, UNLESS EXTENDED.
--------------------------------------------------------------------------------

     THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY
TENDERED AND NOT PROPERLY WITHDRAWN PRIOR TO THE EXPIRATION DATE (DEFINED BELOW)
THAT NUMBER OF SHARES THAT WOULD REPRESENT, ON A FULLY DILUTED BASIS, A MAJORITY
OF ALL OUTSTANDING SHARES.

     The Offer is being made pursuant to an agreement and plan of merger dated
July 28, 1995 (the "Merger Agreement") among the Purchaser, SM Acquiring Co.,
Inc., a Delaware corporation and a direct wholly-owned subsidiary of the
Purchaser (the "Sub"), and the Company. The Merger Agreement provides, among
other things, that after completion of the Offer and the satisfaction or waiver
of certain conditions, the Purchaser will transfer to the Sub all the Shares
held by it, and the Sub will be merged with and into the Company (the "Merger").
At the effective time of the Merger, each outstanding Share (other than Shares
owned by the Company or any subsidiary of the Company, and Shares owned by the
Purchaser, the Sub or any other subsidiary of the Purchaser, or by stockholders,
if any, who properly exercise their appraisal rights under Delaware law) will be
converted into the right to receive $21 in cash without interest.

     Concurrently with the execution of the Merger Agreement, the Purchaser and
the Sub entered into a stockholders agreement dated July 28, 1995 (the
"Stockholders Agreement") with certain stockholders of the Company (the "Selling
Stockholders") owning, in the aggregate, approximately 28% of the Shares.
Pursuant to the Stockholders Agreement, the Selling Stockholders have agreed to
tender pursuant to the Offer and not withdraw an aggregate of 2,871,132 Shares
that are owned of record or beneficially by them plus any Shares issued to them
upon the exercise of outstanding stock options granted to them by the Company
(collectively, the "Founders Shares") or 24% of the Shares calculated on a
fully-diluted basis. Pursuant to the Stockholders Agreement, the Purchaser has
the right to acquire all the Founders Shares under certain circumstances,
including if the Offer is consummated but the Purchaser has not accepted for
payment and paid for the aggregate number of Shares owned by the Selling
Stockholders, or the Offer is terminated by the Purchaser or the Sub due to
failure of certain conditions of the Offer. Such right would be exercisable for
the 30-day period following the occurrence of the events described above.

     THE BOARD OF DIRECTORS OF THE COMPANY (THE "BOARD") HAS UNANIMOUSLY
DETERMINED THAT EACH OF THE OFFER AND MERGER IS FAIR TO, AND IN THE BEST
INTERESTS OF, THE COMPANY'S STOCKHOLDERS, HAS APPROVED THE MERGER AGREEMENT AND
THE TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE OFFER AND MERGER, AND
RECOMMENDS THAT THE COMPANY'S STOCKHOLDERS ACCEPT THE OFFER AND TENDER ALL THEIR
SHARES PURSUANT THERETO.

     Tendering stockholders will not be obligated to pay brokerage fees or
commissions or, except as set forth in Instruction 6 of the Letter of
Transmittal, transfer taxes on the purchase of Shares pursuant to the Offer.

     For purposes of the Offer, the Purchaser will be deemed to have accepted
for payment (and thereby purchased) tendered Shares as, if and when the
Purchaser gives oral or written notice to the depositary (the "Depositary") of
its acceptance of such Shares for payment. Upon the terms and subject to the
conditions of the Offer, payment for Shares purchased pursuant to the Offer will
be made by deposit of the purchase price therefor with the Depositary, which
will act as agent for tendering stockholders for the purposes of receiving
payment from the Purchaser and transmitting payment to tendering stockholders
whose Shares have theretofore been accepted for payment. In all cases, payment
for Shares purchased pursuant to the Offer will be made only after timely
receipt by the Depositary of (i) certificates for such Shares (or a timely
Book-Entry Confirmation (as defined in Section 3 of the Offer to Purchase) with
respect to such Shares), (ii) the Letter of Transmittal (or a manually signed
facsimile), properly completed and duly executed with all required signature
guarantees, and (iii) all other documents required by the Letter of Transmittal.
Under no circumstances will interest be paid on the purchase price for Shares to
be paid by the Purchaser, regardless of any delay in making such payment.

<PAGE>

     The term "Expiration Date" shall mean 12:00 midnight, New York City time,
on Friday, September 1, 1995, unless and until the Purchaser, in accordance with
the terms of the Offer and the Merger Agreement, shall have extended the period
of time during which the Offer is open, in which event the term "Expiration
Date" shall mean the latest time and date at which the Offer, as so extended by
the Purchaser, shall expire. Subject to the terms of the Merger Agreement, the
Purchaser expressly reserves the right, at any time, to extend the period of
time during which the Offer is open for a period of no more than ten business
days and thereby delay acceptance for payment of, or payment for, any Shares by
giving oral or written notice of such extension to the Depositary and by making
a public announcement of such extension. The Purchaser shall not have any
obligation to pay interest on the purchase price for tendered Shares whether or
not the Purchaser exercises its right to extend the period of time during which
the Offer is open. Any such extension will be followed by a public announcement
thereof by no later than 9:00 a.m., New York City time, on the next business day
after the previously scheduled Expiration Date. During any such extension, all
Shares previously tendered and not withdrawn will remain subject to the Offer,
subject to the right of a tendering stockholder to withdraw such stockholder's
Shares. Without limiting the manner in which the Purchaser may choose to make
any public announcement, the Purchaser will have no obligation to publish,
advertise or otherwise communicate any such announcement other than by issuing a
release to the Dow Jones News Service or as otherwise may be required by law.

     Except as otherwise provided below, tenders of Shares are irrevocable.
Shares tendered pursuant to the Offer may be withdrawn any time prior to the
Expiration Date and, unless theretofore accepted for payment by the Purchaser,
may also be withdrawn at any time after October 2, 1995. For a withdrawal to be
effective, a written, telegraphic or facsimile transmission notice of withdrawal
must be timely received by the Depositary at its address set forth on the back
cover of the Offer to Purchase. Any such notice of withdrawal must specify the
name of the person who tendered the Shares to be withdrawn, the number of Shares
to be withdrawn and the name of the registered holder, if different from that of
the person who tendered such Shares. If certificates evidencing Shares have been
delivered or otherwise identified to the Depositary, then prior to the release
of such certificates, the tendering stockholder must also submit the serial
numbers shown on the particular certificates evidencing the Shares to be
withdrawn, and the signature on the notice of withdrawal must be guaranteed by
an Eligible Institution, as defined in Section 3 of the Offer to Purchase
(except in the case of Shares tendered for the account of an Eligible
Institution). If Shares have been tendered pursuant to the procedure for
book-entry transfer set forth in Section 3 of the Offer to Purchase, the notice
of withdrawal must specify the name and number of the account at the applicable
Book-Entry Transfer Facility (as defined in Section 3 of the Offer to Purchase)
to be credited with the withdrawn Shares. All questions as to the form and
validity (including time of receipt) of notices of withdrawal will be determined
by the Purchaser, in its sole discretion, whose determination shall be final and
binding on all parties. Any Shares properly withdrawn will be deemed not validly
tendered for purposes of the Offer, but may be tendered at any subsequent time
prior to the Expiration Date by following any of the procedures described in
Section 3 of the Offer to Purchase.

     The Company has provided the Purchaser with the Company's stockholder list
and security position listings for the purpose of disseminating the Offer to
stockholders. The Offer to Purchase, the related Letter of Transmittal and any
relevant materials will be mailed to record holders of Shares and will be
furnished to brokers, dealers, commercial banks, trust companies and similar
persons whose names, or the name of whose nominees, appear on the Company's
stockholders list or, if applicable, who are listed as participants in a
clearing agency's security position listing, for subsequent transmittal to
beneficial owners of Shares by the Purchaser.

     The information required to be disclosed by paragraph (e)(1)(vii) of Rule
14d-6 under the Securities Exchange Act of 1934, as amended, is contained in the
Offer to Purchase and is incorporated herein by reference.

     THE OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE
WITH RESPECT TO THE OFFER.

     Requests for copies of the Offer to Purchase, the Letter of Transmittal and
other tender offer documents may be directed to the Information Agent as set
forth below, and copies will be furnished promptly at the Purchaser's expense.
Questions or requests for assistance also may be directed to the Information

broker or dealer or other person (other than the Depositary and the Information
Agent) in connection with the solicitation of tenders of Shares pursuant to the
Offer.

FLORHAM PARK, NEW JERSEY, AND CHERRY HILL, NEW JERSEY, JULY 29, 1995 -- Schein
Pharmaceutical, Inc. and Marsam Pharmaceuticals Inc. (NASDAQ:MSAM) today
announced they have entered into a merger agreement.  The agreement provides for
the acquisition by Schein of all the outstanding shares of Marsam for
approximately $240 million in cash, or the equivalent of $21 per share.

Schein will make a cash tender offer for all of the outstanding shares of Marsam
common stock.  This offer will be subject to a number of conditions, including
that the number of shares tendered equals at least a majority of the Marsam
shares, assuming exercise of all outstanding options, and the expiration of the
waiting period under the Hart-Scott-Rodino Antitrust Improvements Act.  The
merger agreement then contemplates that any untendered shares will be converted
into cash at the tender offer price pursuant to a merger as soon as practicable
after the completion of the tender offer.

<PAGE>

Marvin Samson, President and Chief Executive Officer of Marsam, and Agvar
Chemicals Inc., who, in the aggregate, hold approximately 28% of the outstanding
shares of common stock of Marsam, have agreed to tender their shares in the
tender offer and have granted Schein an option to purchase their shares at $21
per share, all in accordance with the terms of such agreement.

Marsam said that its Board of Directors has approved the offer and recommended
its acceptance by stockholders.  The tender offer is expected to commence on
Friday, August 4, 1995, and expire at midnight, New York time, on Friday,
September 1, 1995, unless extended.  The tender offer will only be made pursuant
to definitive tender offer materials, which will be distributed to Marsam's
stockholders and filed with the Securities and Exchange Commission.

Marvin Samson, who will continue as President and Chief Executive Officer of
Marsam, in announcing the prospective merger, said, "We believe that the
synergies between Marsam and Schein present a unique opportunity for growth in
both organizations.  Our complementary strengths and product offerings are
critical success factors in the ever-changing health care environment.  Schein's
management shares our vision for the future, and together we have

Dear Sirs:

     We understand that Schein Pharmaceutical, Inc., a Delaware corporation

(the "Tender Offer") to acquire up to 100% of the outstanding Shares. Promptly
after the acceptance of Shares pursuant to the Tender Offer, Acquisition Co.
will be merged with and into Marsam (the "Merger") in a transaction in which
each outstanding Share not acquired in the Tender Offer will be converted
into the right to receive the cash price paid in respect of the Shares
purchased in the Tender Offer.

     You have advised us that in connection with the Acquisition you will
require the following bank credit facilities in an aggregate principle amount
not to exceed

$350,000,000: (a) pre-Merger facilities (the "Pre-Merger
Facilities") consisting of (i) a senior secured term loan facility (the
"Tender Facility") in the amount of up to $250,000,000 and (ii) a senior
secured revolving credit facility (the "Pre-Merger Revolving Credit
Facility") in an aggregate principal amount up to $100,000,000 and (b)
post-Merger facilities (the "Post-Merger Facilities") consisting of (i) a
senior secured term loan facility (the "Term Facility") in the amount of
$200,000,000 and (ii) a senior secured revolving credit facility (the
"Post-Merger Revolving Facility") in an aggregate principal amount up to
$150,000,000. The Pre-Merger Facilities and the Post-Merger Facilities are
collectively referred to herein as the "Facilities." The Pre-Merger Revolving
Facility and the Post-Merger Revolving Facility are collectively referred to
herein as the "Revolving Facilities."

     Chemical Bank ("Chemical") is pleased to advise you of its commitment to
provide the entire amount of the Facilities, and Chemical Securities Inc.
("CSI") is pleased to advise you of its agreement to act as arranger of the
Facilities, in each case upon the terms and subject to the conditions set
forth or referred to herein and in the Summary of Terms and Conditions
attached hereto as Exhibit A (the "Term Sheet"). It is agreed that (a)
Chemical will act as sole administrative agent and collateral agent for the
Facilities and (b) CSI will act as sole arranger of and manager of the
syndication for the Facilities, and that Chemical and CSI will perform all
functions and exercise all authority customarily performed and exercised by
them in such roles. It is further agreed that no additional agents or
arrangers for the Facilities will be appointed except pursuant to our mutual
agreement, PROVIDED that you may without our consent designate a co-agent and
co-arranger (with the respective roles and compensation of Chemical, CSI and
such co-agent and co-arranger to be mutually agreed upon by Chemical, CSI,
such co-agent and co-arranger and you at the time).

     Chemical reserves the right, prior to or after execution of definitive
documentation with respect to the Facilities, to syndicate all or part of the
Facilities to one or more financial institutions. It is agreed that no
syndicate lender participating in the Facilities will receive compensation
outside the terms contained herein and in the Fee Letter referred to below in
order to obtain its commitment to participate in this financing. You acknowledge
that CSI may commence syndication efforts

promptly after the execution of this Commitment Letter and you agree actively to
assist CSI in achieving a syndication which is satisfactory to it.
Specifically, such assistance shall include your using your best efforts to seek
to ensure that CSI's syndication efforts benefit materially from your lending
relationships and the lending relationships of your controlled affiliates and
Marsam.  This will be accomplished by a variety of means, including direct
contact during the syndication between your senior management and the proposed
syndicate lenders, assistance in the preparation of a confidential information
memorandum and the hosting, with CSI, of a meeting or meetings with proposed
syndicate lenders.  You will also use your best efforts to have senior
management of Marsam participate in such meeting or meetings.

     As consideration for Chemical's commitment hereunder and CSI's agreement
to manage the syndication of the Facilities, you agree to pay the fees set forth
in the Fee Letter dated the date hereof (the "Fee Letter").  Once paid, such
fees shall not be refundable under any circumstances (except to correct errors
in payment).

     To assist CSI in its syndication efforts, you agree promptly to provide,
and to cause your advisors to provide, CSI and the other syndicate lenders upon
request with all information  reasonably deemed necessary by them to complete
successfully the syndication, including but not limited to all information and
projections prepared by you or your advisors on your behalf or by Marsam's
management relating to the transactions described herein.  You hereby represent
and covenant that (a) to the best of the knowledge of your senior management,
all information (excluding financial projections) prepared by you (the
"Information") which is or has been made available to Chemical or CSI by you or
any of your authorized representatives in connection with the transactions
contemplated hereby is complete and correct in all material respects and does
not contain any untrue statement of a material fact or omit to state a material
fact necessary in order to make the statements contained therein not misleading
in light of the circumstances under which such statements are made and (b) all
financial projections (the "Projections") that are or have been prepared by you
and made available to Chemical or CSI have been or will be prepared in good
faith based upon reasonable assumptions.  In arranging and syndicating the
Facilities, CSI will be using and relying on the Infor-

Company, Acquisition Co. and Marsam of a Merger Agreement reasonably
satisfactory in form and substance to Chemical and Chemical's reasonable

prospects of the Company and its subsidiaries (including, following the Merger,
Marsam and its subsidiaries), taken as a whole,  (e) there not existing any
litigation or administrative proceedings or any other legal or regulatory
development, actual or threatened, that, in Chemical's reasonable judgment,  (i)
would be reasonably likely to result in a material adverse effect on the
business, condition (financial or otherwise) operations, assets, liabilities or
prospects of the Company and its subsidiaries (including, following the Merger,
Marsam and its subsidiaries), taken as a whole, or on the rights, remedies and
benefits available to Chemical and the other Lenders under the loan documents,
(ii) would be materially likely to result in any material restriction or
limitation on the transactions contemplated by the Merger Agreement or (iii)
would be materially inconsistent with the assumptions underlying the
Projections, (f)  the acquisition in the Tender Offer of Shares sufficient on a
fully diluted basis to enable the Company, acting alone, promptly to effect all
necessary shareholder approvals and cause the Merger to occur in the accordance
with applicable law and the charter and by-laws of Marsam, (g)  the sources and
uses of funds in connection with the Acquisition being consistent with the
schedule of sources and uses dated June 6, 1995, heretofore delivered by you to
Chemical and (h)  the other conditions set forth in the Term Sheet.

change in financial, banking or capital market conditions since the

have a material adverse effect on the syndication of the Facilities and (b)
CSI's satisfaction that, prior to and during the syndication of the Facilities,
there shall be no issues of debt securities, issues of equity securities or bank
credit facilities of the Company or its subsidiaries, or Marsam and its

capital markets. The terms and conditions of Chemical's commitment hereunder and

are not covered by or made clear under the provisions hereof are subject to
the approval and agreement of Chemical and you.

harmless each of Chemical, CSI and the syndicate lenders and their respective
officers, directors, employees, affiliates and controlling persons from and
against any and all losses, claims, damages and liabilities to which any such
person may become subject arising out of or in connection with this Commitment
Letter, the Facilities or the loans thereunder, the use of any proceeds of such
loans, the Acquisition or any related transaction or any claim, litigation,
investigation or proceeding relating to any of the foregoing, regardless of
whether any of such indemnified parties is a party thereto, and to reimburse
each of such indemnified parties upon demand for any reasonable legal or other
expenses incurred in connection with investigating or defending any of the
foregoing; PROVIDED that the foregoing indemnity will not, as to any indemnified
party, apply to losses, claims, damages, liabilities or related expenses to the
extent they are found by a final decision of a court of competent jurisdiction
to have resulted from the wilful misconduct or gross negligence of such
indemnified party; and (ii) to reimburse each of Chemical and CSI from time to
time for all reasonable out-of-pocket expenses (including expenses of their due
diligence investigation, syndication expenses, travel expenses and reasonable
fees, disbursements and other charges of counsel, consultants and advisors
retained by them) incurred in connection with the Facilities and the preparation
of this Commitment Letter, the Term Sheet, the Fee Letter, the definitive
documentation for the Facilities and the security arrangements in connection

     You agree that you will not disclose this Commitment Letter, the Term
Sheet, the Fee Letter, the contents of any of the foregoing or the activities of
Chemical or CSI pursuant hereto or thereto to any person without the prior
approval of Chemical (which shall not be unreasonably withheld), except that
(a) you may disclose this Commitment Letter, the Term Sheet, the Fee Letter and
the contents hereto and thereof (i) to your officers, directors, employees,
attorneys and advisors on a confidential and need-to-know basis and (ii) as
required by applicable law or compulsory legal process and (b) you may disclose
this Commitment Letter and the Term Sheet and the contents hereof and thereof
and the existence of the Fee Letter on a confidential basis to Marsam and its
attorneys and advisors on a confidential and need-to-know basis in connection
with the transactions contemplated hereby, it being expressly understood and
agreed that neither the Fee Letter nor the contents thereof may be so disclosed
pursuant to this clause (b). The provisions contained in this paragraph shall
remain in full force and effect notwithstanding the termination of this
Commitment Letter or Chemical's commitment hereunder.

agreements contained herein shall in any event terminate, unless Chemical and

                           SUMMARY OF TERMS AND CONDITIONS
                           SENIOR SECURED CREDIT FACILITIES


BORROWER:               Schein Pharmaceutical, Inc., a Delaware corporation
                        (the "Company").

ACQUISITION:             The Company proposes to acquire as described below (the
                        "Acquisition"), through a special purpose acquisition
                        subsidiary to be organized under the laws of the State
                        of Delaware ("Acquisition Co."), all the outstanding
                        common stock (the "Shares") of Marsam Pharmaceuticals
                        Inc. and Subsidiary, a Delaware corporation ("Marsam").
                        The Acquisition will be effected pursuant to a merger
                        agreement (the "Merger Agreement") to be entered into
                        among the Company, Acquisition Co. and Marsam. The
                        Merger Agreement will provide that Acquisition Co. will
                        make a cash tender offer (the "Tender Offer") to
                        acquire up to 100% of the outstanding Shares. Promptly

                        Offer, Acquisition Co. will be merged with and into
                        Marsam (the "Merger") in a transaction in which each
                        outstanding Share not acquired in the Tender Offer will
                        be converted into the right to receive the cash price
                        paid in respect of the Shares purchased in the Tender
                        Offer.

                        "Guarantees") by each existing and subsequently acquired
                        or organized domestic subsidiary of the Company

                        U.S. and non-U.S. banks. The Company will have the right
                        to require any Lender claiming compensation under these
                        provisions to assign its loans and commitments to
                        another financial institution designated by the Company

                        not be unreasonably withheld (except that assignments to
                        another Lender or one of its affiliates or to a Federal
                        Reserve Bank will not require the Company's consent).
                        Assignees will assume all the rights and obligations of
                        the assigning Lender. Each assignment (other than to
                        another Lender or one of its affiliates) will be in a
                        minimum amount of $10,000,000. Assignments of
                        commitments need not be pro rata among the Facilities.
                        Participations will be without restriction and

                          AGREEMENT AND PLAN OF MERGER

                               DATED JULY 28, 1995

          The parties to this agreement and plan of merger are Schein
Pharmaceutical, Inc., a Delaware corporation (the "Parent"), SM Acquiring Co.,
Inc., a Delaware corporation and a wholly-owned subsidiary of the Parent (the
"Sub"), and Marsam Pharmaceuticals Inc., a Delaware corporation (the "Company").

          The board of directors of each of the Parent, the Sub and the Company
has determined it is in the best interests of its stockholders for the Parent to
acquire the Company upon the terms and subject to the conditions set forth in
this agreement.

          Accordingly, the parties agree as follows:

1.   THE OFFER

     1.1  THE OFFER.

          (a)  Provided this agreement shall not have been terminated in
accordance with section 8.1, promptly (but in no event later than five business
days following the public announcement of the terms of this agreement), the
Parent shall commence (within the meaning of Rule 14d-2 under the Securities
Exchange Act of 1934 (the "Exchange Act")), or cause the Sub to commence, an
offer to purchase all the outstanding shares of common stock of the Company, par
value $.01 per share (the "Shares"), at a price of $21.00 per Share, net to the
seller in cash (the "Offer").  The obligation to consummate the Offer and to
accept for payment and to pay for any Shares tendered pursuant to the Offer
shall be subject only to those conditions set forth in exhibit A.  The Company
agrees that no Shares held by the Company or any of its subsidiaries shall be
tendered to the Parent or the Sub pursuant to the Offer.  Neither the Parent nor
the Sub shall, without the prior written consent of the Company, (i) decrease or
change the form of the consideration payable in the Offer, (ii) decrease the
number of Shares sought pursuant to the Offer, (iii) impose additional
conditions to the Offer, (iv) change the conditions to the Offer, except the
Parent or the Sub, as applicable, in its sole discretion may waive any condition
to the Offer, other than the condition set forth in clause (1) of exhibit A,
which may not be waived without the Company's prior written consent, or (v) make
any other change in the terms of the Offer adverse to the holders of the Shares.
The Parent or the Sub, as applicable, agrees that, subject to the terms and
conditions of the Offer and this agreement, it will accept for payment and pay
for all Shares validly tendered and not withdrawn pursuant to the Offer promptly
after expiration of the Offer.  The Offer shall initially provide that the Offer
shall expire 20 business days after it is commenced or on September 1, 1995,
whichever is later.  The Parent or the Sub, as applicable, may

<PAGE>

extend the Offer in accordance with applicable law, but if the conditions set
forth in exhibit A are satisfied as of the then scheduled expiration date of the
Offer, the Offer may be extended only with the prior written consent of the
Company or as required by law; provided that the Parent or the Sub, as
applicable, may, without the consent of the Company, extend the Offer on one
occasion for a period not to exceed 10 business days, if the number of Shares
tendered, together with any Shares beneficially owned by the Parent or the Sub,
is less than 90% of the Shares outstanding on the scheduled expiration date of
the Offer.  If the conditions set forth in exhibit A are not satisfied or, to
the extent permitted by this agreement, waived by the Parent or the Sub, as
applicable, as of the scheduled expiration date, the Parent or the Sub, as
applicable, shall extend the Offer from time to time until the earliest of the
consummation of the Offer, November 30, 1995 (provided, that neither the Parent
nor the Sub shall be obligated to make any such extension, if, in the reasonable
belief of the Parent or the Sub, as applicable, all such conditions are not
capable of being satisfied by that date) or the termination of this agreement.
Any individual extension of the Offer shall be for a period of no more than 10
business days.

          (b)  On the date of commencement of the Offer, the Parent or the Sub,
as applicable, shall file or cause to be filed with the Securities and Exchange
Commission (the "SEC") a Tender Offer Statement on Schedule 14D-1 (together with
all amendments, the "Schedule 14D-1") with respect to the Offer, which shall
contain the Offer to purchase and related letter of transmittal and other
ancillary Offer documents and instruments pursuant to which the Offer will be
made (collectively, with any supplements or amendments, the "Offer Documents").
The Parent or the Sub, as applicable, shall disseminate the Offer Documents to
holders of the Shares.  Each of the Parent or the Sub, as applicable, and the
Company agrees promptly to correct any information provided by it for use in the
Offer Documents that becomes false or misleading in any material respect, and
the Parent and the Sub shall take all steps necessary to cause the Offer
Documents as so corrected to be filed with the SEC and to be disseminated to
holders of the Shares, in each case as and to the extent required by law.  The
Company and its counsel shall have a reasonable opportunity to review and
comment on the Offer Documents prior to the filing of the respective Offer
Documents with the SEC.  The Parent or the Sub, as applicable, shall provide the
Company and its counsel with any comments that may be received from the SEC or
its staff with respect to the Offer Documents promptly after receipt.  The Offer
Documents shall comply as to form in all material respects with the requirements
of the Exchange Act and the rules and regulations under the Exchange Act.  The
Parent and the Sub agree that none of the information in the Offer Documents or
any related schedule required to be filed with the SEC or in any related
amendment shall, on the date of filing with the SEC or on the date first
published, sent or given to stockholders of

                                        2

the Company, as the case may be, contain an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they are made, not misleading (but excluding statements made in any of the
foregoing documents based on information supplied by the Company specifically
for inclusion therein).  The Parent and the Sub agree that none of the
information supplied by the Parent or the Sub or any of their affiliates
specifically for inclusion in the Proxy Statement (as defined in section 1.2) or
Schedule 14D-9 (as defined in section 1.2) or any related amendment shall, at
the date of filing with the SEC, and, in the case of the Proxy Statement, at the
time the Proxy Statement is mailed and at the time of the Special Meeting (as
defined in section 2.8), contain an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they are
made, not misleading.

that, in the opinion of Bear, Stearns & Co. Inc., the consideration to be paid
to the Company's stockholders in the Offer and Merger is fair, from a financial
point of view, to those stockholders.  As promptly as practicable after
commencement of the Offer, the Company shall, subject to the terms and
conditions set forth in this agreement, file with the SEC a
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-9")
containing the recommendations of its board of directors in favor of the Offer
and Merger and shall permit the inclusion in the Offer Documents of such
recommendations, in each case subject to the fiduciary duties of the board of
directors of the Company as advised by outside counsel.  The Company, the Parent
and the Sub shall promptly correct any information provided by them for use in
the Schedule 14D-9 that becomes false or misleading in any material respect, and
the Company shall take all steps necessary to cause the Schedule 14D-9 as so
corrected to be filed with the SEC and to be disseminated to holders of the
Shares, in each case as and to the extent required by law.  The Parent and its
counsel shall

                                        3

<PAGE>

have a reasonable opportunity to review and comment on the Schedule 14D-9 prior
to its filing with the SEC.  The Company agrees to provide the Parent and its
counsel with any comments that may be received from the SEC or its staff with
respect to the Schedule 14D-9 promptly after receipt.  The Company agrees that
neither the Schedule 14D-9, nor any related amendments nor any information
supplied by the Company specifically for inclusion in the Offer Documents or the
Proxy Statement (but excluding statements made in any of the foregoing documents
based on information supplied by the Parent or Sub or any of their affiliates
specifically for inclusion therein) shall, at the respective times the Schedule
14D-9 or Offer Documents are filed with the SEC or are first published, sent or
given to stockholders, as the case may be, contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they are made, not misleading.  The Schedule 14D-9 and the Proxy
Statement shall comply as to form in all material respects with the applicable
requirements of the Exchange Act and the rules and regulations under the
Exchange Act.  The letter to stockholders, notice of meeting, proxy statement
and form of proxy, or the information statement, as the case may be, that may be
distributed to stockholders in connection with the Merger (including any
supplements), and any schedules required to be filed with the SEC in connection
therewith, as from time to time amended or supplemented, are collectively
referred to as the "Proxy Statement".

     1.3  STOCKHOLDER LISTS.  In connection with the Offer, the Company shall
promptly furnish the Sub with mailing labels, security position listings and any
available listing or computer file containing the names and addresses of the
record holders of the Shares as of a recent date and shall furnish the Sub with
such information and assistance as the Sub or its agents may reasonably request
in communicating the Offer to the record and beneficial stockholders of the
Company.  Subject to the requirements of applicable law and except for such
steps as are necessary to disseminate the Offer Documents and any other
documents necessary to consummate the Offer and Merger, the Parent and Sub and
their affiliates and associates shall hold in confidence such listings and other
information, shall use such information only in connection with the Offer and
Merger and, if this agreement is terminated in accordance with its terms, shall
deliver to the  Company all copies of all such information (and extracts or
summaries of such information) then in their or their agents' or advisors'
possession.

     1.4  DIRECTORS

          (a)  Promptly upon the purchase by the Parent or the Sub, as
applicable, pursuant to the Offer of a number of Shares that represents at least
a majority of the outstanding Shares on

                                        4

<PAGE>

a fully-diluted basis and from time to time thereafter, the parties shall,
subject to the provisions of section 14(f) of the Exchange Act and Rule 14f-1
under the Exchange Act, promptly use all reasonable efforts necessary to cause
the persons listed on schedule 2.5 to comprise the entire board of directors of
the Company.  The date on which such persons first comprise the Company's board
of directors is referred to as the "Control Date".

          (b)  From and after the Control Date and prior to the Effective Time
and as long as there is at least one director who is designated as a "Continuing
Director" on schedule 2.5 (a "Continuing Director" and, collectively, the
"Continuing Directors"), if requested by a majority of the Continuing Directors,
all other directors shall abstain from acting upon, and the approval of a
majority of the Continuing Directors shall be required to authorize, any
termination of this agreement by the Company, any amendment of this agreement
requiring action by the board of directors of the Company, any extension of time
for the performance of any obligation or other act of the Parent or the Sub
under this agreement and any waiver of compliance with any provision of this
agreement for the benefit of the Company.


2.   THE MERGER

     2.1  THE MERGER.  Upon the terms of this agreement and subject to the
provisions of the DGCL, the Parent shall transfer to the Sub all Shares held by
it, and the Sub shall be merged with and into the Company (the "Merger") as soon
as practicable following the satisfaction or waiver, if permissible, of the
conditions set forth in section 7.  The Company shall be the surviving
corporation in the Merger (the "Surviving Corporation") under the name "Marsam
Pharmaceuticals Inc." and shall continue its existence under the law of
Delaware.  At the Effective Time, the separate corporate existence of the Sub
shall cease.

     2.2  CONSUMMATION OF THE MERGER.  Subject to the provisions of this
agreement, the parties shall cause the Merger to be consummated by filing with
the secretary of state of the state of Delaware a duly executed and verified
certificate of merger, and shall take all other action required by law to effect
the Merger.  Prior to the filing referred to in this section, a closing (the
"Closing") shall be held at the offices of Proskauer Rose Goetz & Mendelsohn
LLP, 1585 Broadway, New York, New York (or such other place as the parties may
agree) for the purpose of completing the foregoing.  The time the Merger becomes
effective in accordance with applicable law is referred to as the "Effective
Time".

     2.3  EFFECTS OF THE MERGER.  The Merger shall have the effects set forth in
the DGCL and this agreement.

                                        5

<PAGE>

     2.4  CERTIFICATE OF INCORPORATION AND BY-LAWS.  The certificate of
incorporation and by-laws of the Sub, as in effect on the date of this
agreement, shall be the certificate of incorporation and by-laws, respectively,
of the Surviving Corporation; PROVIDED, HOWEVER, that section 1 of the
certificate of incorporation of the Surviving Corporation shall be amended to
read in its entirety as follows:  "Section 1.  The name of the Corporation is
Marsam Pharmaceuticals Inc."

     2.5  DIRECTORS AND OFFICERS.  The persons listed on schedule 2.5 and the
officers of the Company immediately prior to the Effective Time shall be the
directors and officers, respectively, of the Surviving Corporation, until their
respective successors are duly elected and qualified.

     2.6  CONVERSION OF SHARES.  Each Share issued and outstanding immediately
prior to the Effective Time (other than Shares owned by the Parent, the Sub or
any subsidiary of the Parent or Sub or held in the treasury of the Company, all
of which shall be cancelled, and other than Dissenting Shares (as defined in
section 3.1)) shall, by virtue of the Merger and without any action on the part
of the Parent, the Sub, the Company or the holder, be converted into the right
to receive in cash an amount per Share (subject to any applicable withholding
tax, as specified in section 2.10) equal to the highest price per share payable
in the Offer, without interest (the "Merger Consideration"), upon the surrender
of the certificate representing the Share in accordance with section 3.2.

     2.7  CONVERSION OF COMMON STOCK OF THE SUB.  Each share of common stock,
par value $.01, of the Sub issued and outstanding immediately prior to the
Effective Time shall, by virtue of the Merger and without any action on the part
of the Parent, the Sub or the Company, be converted into and become one share of
common stock of the Surviving Corporation.

     2.8  STOCKHOLDERS' MEETING.  Unless the Merger is consummated in accordance
with section 253 of the DGCL as contemplated by section 2.9, and subject to
applicable law, the Company, acting through its board of directors, shall, in
accordance with applicable law, duly call, give notice of, convene and hold a
special meeting (the "Special Meeting") of its stockholders as soon as
practicable following the consummation of the Offer for the purpose of
considering and taking action upon the agreement of merger (within the meaning
of section 251 of the DGCL) set forth in this agreement; and, subject to the
fiduciary duties of its board of directors under applicable law as advised by
outside counsel, the Company shall include in the Proxy Statement the
recommendation of its board of directors that stockholders of the Company vote
in favor of the approval and adoption of the agreement of merger set forth in
this agreement.  The Parent and the Sub agree that, at the Special Meeting, all
the Shares acquired pursuant to the Offer or otherwise by the

                                        6

<PAGE>

Parent or Sub or any of their affiliates shall be voted in favor of the approval
and adoption of the agreement of merger set forth in this agreement.

     2.9  MERGER WITHOUT MEETING OF STOCKHOLDERS.  Notwithstanding section 2.8,
if the Parent, directly or indirectly through the Sub or any other subsidiary,
acquires at least 90 percent of the outstanding Shares, each of the Parent, the
Sub and the Company shall take all necessary and appropriate action to cause the
Merger to become effective, as soon as practicable after the consummation of the
Offer, without a meeting of stockholders of the Company, in accordance with
section 253 of the DGCL.

     2.10 WITHHOLDING TAXES.  If so specified in the Offer Documents, the Parent
and Sub shall be entitled to deduct and withhold from the consideration
otherwise payable to a holder of Shares or Options pursuant to the Offer or
Merger such amounts as are required under section 3406 of the Internal Revenue
Code of 1986 (the "Code").  To the extent amounts are so withheld by the Parent
or Sub, the withheld amounts shall be treated for all purposes of this agreement
as having been paid to the holder of the Shares in respect of which the
deduction and withholding was made by the Parent or Sub, in the circumstances
described in the Offer Documents.


3.   DISSENTING SHARES; PAYMENT FOR SHARES; OPTIONS

     3.1  DISSENTING SHARES.  Notwithstanding anything in this agreement to the
contrary, Shares issued and outstanding immediately prior to the Effective Time
and held by any stockholder who did not vote in favor of the Merger and comply
with section 262 of the DGCL (the "Dissenting Shares") shall not be converted
into or be exchangeable for the right to receive the Merger Consideration,
unless and until any such stockholder shall have failed to perfect or shall have
effectively withdrawn or lost his rights to appraisal under the DGCL.  If any
such holder shall have failed to perfect or shall have effectively withdrawn or
lost that right, that holder's Shares shall thereupon be converted into and
become exchangeable for the right to receive, as of the Effective Time, the
Merger Consideration without any interest.  The Company shall give the Parent or
the Sub, as applicable, (a) prompt notice of any written demands for appraisal
of any Shares, attempted withdrawals of such demands and any other instruments
served pursuant to the DGCL and received by the Company relating to
stockholders' rights of appraisal and (b) the opportunity to direct all
negotiations and proceedings with respect to demands for appraisal under the
DGCL.  The Company shall not, except with the prior written consent of the
Parent or the Sub, as applicable, voluntarily make any payment with respect to
any demands for appraisal of capital

                                        7

<PAGE>

stock of the Company, offer to settle or settle any demands or approve any
withdrawal of any such demands.

     3.2  PAYMENT FOR SHARES

          (a)  Prior to the Effective Time, the Parent shall cause the Sub to
deposit with Chemical Bank (or another bank or trust company reasonably
satisfactory to the Company) (the "Paying Agent") sufficient funds to make the
payments pursuant to section 2.6 on a timely basis to holders of Shares issued
and outstanding immediately prior to the Effective Time (such funds, the
"Payment Fund").  The Paying Agent shall, pursuant to irrevocable instructions,
make the payments provided for in the preceding sentence out of the Payment
Fund.  The Payment Fund shall not be used for any purpose, except as provided in
this agreement.

          (b)  Promptly after the Effective Time, the Surviving Corporation
shall cause the Paying Agent to mail to each record holder of Shares, as of the
Effective Time, a form of letter of transmittal, the form and content of which
shall be reasonably acceptable to the Company (which shall specify that delivery
shall be effected, and risk of loss and title to the certificates representing
the Shares (the "Certificates") shall pass, only upon proper delivery of the
Certificates to the Paying Agent), and instructions for use in effecting the
surrender of the Certificates for payment of the Merger Consideration.  Upon
surrender to the Paying Agent of a Certificate, together with the letter of
transmittal duly executed, the holder of the Certificate shall be paid cash in
an amount (subject to any applicable withholding tax, as specified in section
2.10) equal to the product of the number of Shares represented by the
Certificate and the Merger Consideration, and the Certificate shall be
cancelled.  No interest shall be paid or accrued on the cash payable upon the
surrender of a Certificate.  If payment is to be made to a person other than the
person in whose name a Certificate surrendered is registered, it shall be a
condition of payment that the Certificate so surrendered be properly endorsed or
otherwise in proper form for transfer and that the person requesting such
payment pay any transfer or other taxes required by reason of the payment to a
person other than the registered holder of the Certificate surrendered or
establish to the satisfaction of the Surviving Corporation that the tax has been
paid or is not applicable.  From and after the Effective Time and until
surrendered in accordance with this section 3.2, each Certificate (other than
Certificates representing Shares owned by the Parent or Sub or any of their
subsidiaries, and Dissenting Shares) shall represent for all purposes solely the
right to receive in cash an amount equal to the product of the Merger
Consideration and the number of Shares evidenced by the Certificate, without
interest.

                                        8

<PAGE>

          (c)  Any portion of the Payment Fund (including the proceeds of any
investments of the Payment Fund) that remains unclaimed by the former
stockholders of the Company for six months after the Effective Time shall be
repaid to the Surviving Corporation.  Any former stockholders of the Company who
have not theretofore complied with section 3.1 shall thereafter look only to the
Surviving Corporation (subject to abandoned property, escheat or other similar
laws) for payment of their claim for the Merger Consideration per Share, without
interest.  Neither the Parent, the Sub nor the Surviving Corporation shall be
liable to any holder of Shares for any monies delivered from the Payment Fund or
otherwise to a public official pursuant to any applicable abandoned property,
escheat or similar law.

     3.3  CLOSING OF THE COMPANY'S TRANSFER BOOKS.  At the Effective Time, the
stock transfer books of the Company shall be closed and no transfer of Shares
shall thereafter be made.  If, after the Effective Time, Certificates are
presented to the Surviving Corporation, they shall be cancelled and exchanged
for cash as provided in this section 3, subject to applicable law in the case of
Dissenting Shares.

     3.4  OPTIONS.  Upon the consummation of the Offer, the Parent or the Sub,
as applicable, shall pay each holder of a then outstanding option to purchase
Shares under the Company's 1986 Stock Option Plan, 1993 Stock Option Plan or
1995 Stock Purchase Plan (collectively, the "Stock Option Plans"), whether or
not then exercisable (collectively, the "Options"), in settlement of the
Options, for each Share subject to an Option, an amount (subject to any
applicable withholding tax) in cash equal to the excess, if any, of the Merger
Consideration over the per Share exercise price of that Option (that amount, the
"Option Consideration"); PROVIDED, HOWEVER, that with respect to any person
subject to section 16 of the Exchange Act, any such amount shall be paid by the
Surviving Corporation as soon as practicable after the first date payment can be
made without liability to that person under section 16(b) of the Exchange Act.
Upon receipt of the Option Consideration, the Option shall be cancelled.  The
surrender of an Option to the Company in exchange for the Option Consideration
shall be deemed a release of all rights the holder had or may have had in
respect of that Option.  Prior to the Effective Time, the Company shall use all
reasonable efforts to obtain all necessary consents or releases from holders of
Options under the Stock Option Plans and take all other action necessary to give
effect to the transactions contemplated by this section 3.4.  Except as
otherwise agreed by the parties, (a) all Stock Option Plans shall terminate as
of the Effective Time and all rights under any provision of any other plan,
program or arrangement providing for the issuance or grant of any other interest
in respect of the capital stock of the Company or any subsidiary of the Company
shall be cancelled as of the Effective Time, and (b) the Company shall take all
reasonable action to ensure that, after the Effective Time, no person shall have
any

                                        9

<PAGE>

right under any Stock Option Plan (or any option granted under any Stock Option
Plan) or other plan, program or arrangement with respect to equity securities of
the Company, the Surviving Corporation or any direct or indirect subsidiary of
either.


4.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company represents and
warrants to the Parent and Sub as follows:

     4.1  ORGANIZATION AND QUALIFICATION.  Each of the Company and its
subsidiaries is a duly organized and validly existing corporation in good
standing under the law of its jurisdiction of incorporation, with the corporate
power and authority to own its properties and conduct its business as now being
conducted, and is duly qualified and in good standing as a foreign corporation
authorized to do business in each jurisdiction in which the character of the
properties owned or held under lease by it or the nature of the business
transacted by it makes such qualification necessary, except where the failure to
be so qualified and in good standing would not have a Material Adverse Effect
(as defined in section 9.9).  The Company has made available to the Parent
accurate and complete copies of the certificates of incorporation and by-laws as
currently in effect of the Company and each of its subsidiaries.

     4.2  CAPITALIZATION

Shares were issued and outstanding; no shares of Preferred Stock were issued or
outstanding; no Shares were held in the Company's treasury; and there were

Company, or obligations of the Company to issue, any capital stock, voting
securities or securities convertible into or exchangeable for capital stock or
voting securities of the Company, or obligations of the Company to grant, extend

section 4.2(a) of the Disclosure Letter, there are no outstanding obligations of
the Company or any subsidiary to repurchase, redeem or otherwise acquire any

of its subsidiaries is a party with respect to the voting of capital stock of
the Company or any of its subsidiaries.

          (b)  Except as set forth in section 4.2(b) of the Disclosure Letter,
the Company is, directly or indirectly, the record and beneficial owner of all
the outstanding shares of capital stock of each of its subsidiaries, free and
clear of any lien, mortgage, pledge, charge, security interest or encumbrance,
and there are no irrevocable proxies with respect to any such shares.  Except as
set forth in section 4.2(b) of the Disclosure Letter, there are no outstanding
(i) securities of the Company or any subsidiary convertible into or exchangeable
for shares of capital stock or other voting securities or ownership interests in
any subsidiary, or (ii) options or other rights to acquire from the Company or
any of its subsidiaries, or other obligations of the Company or any of its
subsidiaries to issue, any capital stock, voting securities or other ownership
interests in, or any securities convertible into or exchangeable for any capital

other obligations of the Company or any of its subsidiaries to grant, extend or
enter into any subscription, warrant, right, convertible or exchangeable
security or other similar agreement or commitment (the items in  clauses (i) and
(ii), collectively, the "Subsidiary Securities").  Except as set forth in
section 4.2(b) of the Disclosure Letter, there are no outstanding obligations of
the Company or any of its subsidiaries to repurchase, redeem or otherwise
acquire any outstanding Subsidiary Securities.

     4.3  AUTHORITY FOR THIS AGREEMENT.  The Company has the requisite corporate
power and authority to execute and deliver this agreement and to consummate the
transactions contemplated by this agreement.  The execution and delivery of this
agreement by the Company and the consummation by the Company of the transactions
contemplated by this agreement have been duly and validly authorized by the
board of directors of the Company and no other corporate proceedings on the part

<PAGE>

adoption of the agreement of merger (within the meaning of section 251 of the
DGCL) in this agreement by the holders of a majority of the Shares prior to the
consummation of the Merger, if required by applicable law).  This agreement has
been duly and validly executed and delivered by the Company and, assuming this
agreement constitutes the valid and binding obligation of each of the Parent and
Sub, constitutes a valid and binding agreement of the Company, enforceable
against the Company in accordance with its terms, except as enforceability may
be limited by applicable bankruptcy, insolvency and similar laws affecting
creditors' rights generally and subject to general principles of equity (whether
considered in a proceeding in equity or at law).

their respective businesses only in the ordinary course consistent with past
practice, except in connection with the negotiation and execution and delivery
of this agreement and the exploration of other alternative transactions, and (c)

or other distribution in respect of the Shares or any repurchase, redemption or
other acquisition by the Company or any of its subsidiaries of any outstanding

the Company or any of its subsidiaries; (ii) any entry into any written
employment agreement (other than the agreements identified in section 4.4 of the
Disclosure Letter that are being entered into contemporaneously with this
agreement) with, or any increase in the rate or terms (including, without
limitation, any acceleration of the right to receive payment pursuant to
arrangements set forth in section 4.4 of the Disclosure Letter) of compensation
payable or to become payable by the Company or any of its subsidiaries to, their
respective directors or officers; (iii) any increase in the rate or terms
(including, without limitation, any acceleration of the right to receive
payment) of any bonus, insurance, pension or other employee benefit plan,
payment or arrangement made to, for or with any such directors, officers or key
employees, except increases occurring in the ordinary course of business or as
required by law or as necessary to maintain tax-qualified status; or (iv) any
action by the Company that, if taken after the date of this agreement, would
constitute a breach of section 6.1.

of the terms, conditions or provisions of any material note, license, agreement
or other instrument or obligation to which the Company is a party or by which
the Company or any of its assets or subsidiaries may be bound; or (d) violate in
any material respect any material order, writ, injunction, decree, statute, rule

          (a)  Until the termination of this agreement, the Company shall not,
and shall not permit any of its subsidiaries, or any of its or their officers,

any inquiries or the making of any proposal that constitutes, or

                                       23

<PAGE>

may reasonably be expected to lead to, an Acquisition Proposal (as defined
below), or enter into or maintain or continue discussions or negotiate with any
person or entity in furtherance of such inquiries or to obtain an Acquisition
Proposal or agree to or endorse any Acquisition Proposal, or authorize or permit
any of its or their officers, directors or employees or any of its subsidiaries
or any investment banker, financial advisor, attorney, accountant or other
representative retained by it or any of its subsidiaries to take any such
action; PROVIDED, HOWEVER, that nothing in this agreement shall prohibit the

into, maintaining or continuing discussions or negotiations with, any person or

agreement regarding an Acquisition Proposal or (b) makes an unsolicited
Acquisition Proposal, if the board of directors of the Company, after
consultation with and based upon the advice of independent legal counsel (who

good faith that such action is necessary for the board of directors of the
Company to comply with its fiduciary duties to stockholders under applicable law
and, prior to taking such action, the Company (i) provides reasonable notice to
the Parent to the effect that it is taking such action (unless the board of
directors of the Company determines in good faith after consultation with and

breach the fiduciary duties of the board in connection with an Acquisition
Proposal that is more favorable to the stockholders of the Company than the
Offer and the Merger (a "Superior Proposal")) and (ii) receives from such person
or entity an executed confidentiality agreement in reasonably customary form.
The Company shall use reasonable efforts to keep the Parent informed of the
status of any such Acquisition Proposal (unless the board of directors of the
Company determines in good faith after consultation with and based upon the
advice of independent legal counsel that keeping the Parent so informed would
breach the fiduciary duties of the board in connection with a Superior
Proposal).  For purposes of this agreement, "Acquisition Proposal" means an
inquiry, offer or proposal regarding any of the following (other than the
transactions contemplated by this agreement with the Parent or Sub) involving
the Company or any of its subsidiaries:  (w) any merger, consolidation, share
exchange, recapitalization, business combination or other similar transaction;
(x) any sale, lease, exchange, mortgage, pledge, transfer or other disposition
of all or substantially all the assets of the Company and its subsidiaries,
taken as a whole, in a single transaction or series of related transactions; (y)
any tender offer or exchange offer for 20 percent or more of the outstanding
shares of capital stock of the Company or the filing of a registration statement
under the Securities Act of 1933 in connection therewith; or (z) any public
announcement of a proposal, plan or intention to do any of the foregoing or any
agreement to engage in any of the foregoing.

directors of the Company shall not (i) withdraw or modify, or propose to
withdraw or modify, in a manner adverse to the Parent or the Sub, the approval
or recommendation by the board of directors of the Offer, this agreement or the
Merger, (ii) approve or recommend, or propose to approve or recommend, any
Acquisition Proposal or (iii) cause the Company to enter into any agreement with
respect to any Acquisition Proposal.  Notwithstanding the foregoing, in the
event that prior to the time of acceptance for payment of Shares in the Offer
the board of directors of the Company determines in good faith, after
consultation with and based upon the advice of independent legal counsel, that
it is necessary to do so in order to comply with its fiduciary duties to the
Company's stockholders under applicable law, the board of directors of the
Company may withdraw or modify its approval or recommendation of the Offer, this
agreement and the Merger, approve or recommend a Superior Proposal or cause the
Company to enter into an agreement with respect to a Superior Proposal.  The
Company shall provide reasonable notice to the Parent or the Sub to the effect
that it is taking such action.  If the Company proposes to enter into an
agreement with respect to any Superior Proposal, it shall concurrently with
proposing such an agreement pay, or cause to be paid, to the Parent the fee
provided for in section 6.10.

     6.3  ACCESS TO INFORMATION

          (a)  Subject to any limitations imposed by applicable law, between the
date of this agreement and the Control Date, the Company shall (i) give the
Parent and Sub and their authorized representatives all reasonable access
(during regular business hours upon reasonable notice) to all employees, plants,
offices, warehouses and other facilities and to all books and records
(including, without limitation, tax returns) of the Company and its subsidiaries
and cause the Company's and its subsidiaries' independent accountants to provide
access to their work papers and such other information as the Parent or Sub may
reasonably request, (ii) permit the Parent and Sub to make such inspections as
they may reasonably require and (iii) cause its officers and those of its
subsidiaries to furnish the Parent and Sub with such financial and operating
data and other information with respect to the business, properties and
personnel of the Company and its subsidiaries as the Parent or Sub may from time
to time reasonably request.

          (b)  All information obtained by the Parent or Sub pursuant to this
section 6.3 shall constitute Evaluation Material and shall be subject to the
provisions of the letter agreement dated May 15, 1995 between the Parent and the
Company (the "Confidentiality Agreement") relating to the confidential treatment
of Evaluation Material (as defined in the Confidentiality Agreement).

                                       25

     6.4  REASONABLE EFFORTS.  Subject to the terms of this agreement and the
fiduciary duties of the board of directors of the Company under applicable law
as advised by independent legal counsel, each of the parties agrees to use all
reasonable efforts to take, or cause to be taken, all appropriate action, and to
do, or cause to be done, all things necessary, proper or advisable under
applicable law to consummate and make effective, in the most expeditious manner
practicable, the transactions contemplated by this agreement.  Without limiting
the foregoing, (a) the Company and its board of directors shall use all
reasonable efforts promptly to make any required submissions under the HSR Act
that the Company and Parent determine should be made, in each case with respect
to the Offer, the Merger and the transactions contemplated by this agreement,
and (b) the parties shall cooperate with one another (i) in promptly determining
whether any filings are required to be or should be made or consents, approvals,
permits or authorizations are required to be or should be obtained under any
other federal, state or foreign law or regulation or whether any consents,
approvals or waivers are required to be or should be obtained from other parties
to loan agreements or other contracts or instruments material to the Company's
business in connection with the consummation of the Offer, the Merger and the
transactions contemplated by this agreement, and (ii) in promptly making any
such filings, furnishing information required in connection with such filings
and seeking to obtain timely any such consents, permits, authorizations,
approvals or waivers.

     6.5  INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE

          (a)  The Parent and Sub agree that all rights to indemnification or
exculpation now existing in favor of the directors, officers, employees and
agents of the Company and its subsidiaries as provided in their respective
charters or by-laws or otherwise in effect as of the date of this agreement with
respect to matters occurring prior to the Effective Time shall survive the
Merger and shall continue in full force and effect.  To the maximum extent
permitted by the DGCL, such indemnification shall be mandatory rather than
permissive and the Surviving Corporation shall advance expenses in connection
with such indemnification.  The by-laws of the Surviving Corporation shall
contain provisions substantially similar to the provisions with respect to
indemnification and insurance set forth in Article ELEVENTH of the Company's
restated certificate of incorporation, as amended, which provisions shall not be
amended in any manner that would adversely affect the rights under those by-laws
of the Company's employees, agents, directors or officers for acts or omissions
on or prior to the Effective Time, except if such amendment is required by law.


          (b)  In addition to the rights provided for in section 6.5(a), and not
in limitation of those rights, the Parent shall cause the Surviving Corporation
to indemnify, defend and hold

                                       26

<PAGE>

harmless each present and former director and officer, employee and agent of the
Company and its subsidiaries ("Indemnified Parties") to the fullest extent
permitted by law for all claims, losses, damages, liabilities, costs, judgments
and amounts paid in settlement, including advancement of expenses (including
attorneys' fees) as incurred in respect of any threatened, pending or
contemplated claim, action, suit or proceeding, whether criminal, civil,
administrative or investigative, including, without limitation, any action by or
on behalf of any or all security holders of the Company or by or in the right of
the Company or the Surviving Corporation, or investigation relating to any
action or omission by such party in its capacity as such (including service to
any other entity, plan, trust or the like at the Company's request) occurring on
or prior to the Effective Time (including, without limitation, any that arise
out of or relate to the transactions contemplated by this agreement).

          (c)  The Parent shall cause the Surviving Corporation to maintain in
effect for not fewer than six years from the Effective Time the policies of
directors' and officers' liability insurance most recently maintained by the
Company (provided that the Surviving Corporation may substitute therefor
policies with reputable and financially sound carriers of at least the same
coverage and containing terms and conditions no less advantageous, as long as
such substitution does not result in gaps or lapses in coverage) with respect to
claims arising from or related to matters occurring prior to the Effective Time;
PROVIDED, HOWEVER, that in no event shall the Surviving Corporation be required
to expend more than an amount per year equal to 200% of the current annual
premiums paid by the Company (the "Premium Amount") to maintain or procure
insurance coverage pursuant to this section 6.5(c); and FURTHER PROVIDED that,
if the Surviving Corporation is unable to obtain the insurance called for by
this section 6.5(c), the Surviving Corporation shall obtain as much comparable
insurance as is available for the Premium Amount per year.  The Parent shall
cause the Surviving Corporation to pay all expenses (including reasonable
attorneys' fees) that may reasonably be incurred by the Indemnified Party in
successfully enforcing the rights to which the Indemnified Party is entitled
under this agreement or the Surviving Corporation's by-laws or is otherwise
entitled.  The Parent agrees that, should the Surviving Corporation fail to
comply with the foregoing obligations, the Parent shall be responsible for those
obligations.

          (d)  In the event the Surviving Corporation or Parent or any of their
successors or assigns (i) consolidates with or merges into any other person and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any person, then, and in each such case, proper
provisions shall be made so that the successors and assigns of

                                       27

<PAGE>

the Surviving Corporation or Parent shall assume its obligations set forth in
this section 6.5.

          (e)  The provisions of this section 6.5 are intended to be for the
benefit of, and shall be enforceable by, each Indemnified Party, his or her
heirs and his or her personal representatives.

     6.6  STATE TAKEOVER STATUTES.  The Company shall, upon the request and at
the expense of the Parent, take all reasonable steps to assist in any challenge
by the Parent or the Sub to the validity, or applicability to the Offer or
Merger, of any state takeover law.

     6.7  PROXY STATEMENT.  Unless the Merger is consummated in accordance with
section 253 of the DGCL as contemplated by section 2.9, the Company shall
prepare and file with the SEC, and in consultation with the Parent and Sub, as
soon as practicable after the consummation of the Offer, a preliminary proxy or
information statement (the "Preliminary Proxy Statement") relating to the Merger
in accordance with the Exchange Act and the rules and regulations under the
Exchange Act, with respect to the transactions contemplated by this agreement.
The Company, the Parent and the Sub shall cooperate with each other in the
preparation of the Preliminary Proxy Statement.  The Company shall use all
reasonable efforts to respond promptly to any comments made by the SEC with
respect to the Preliminary Proxy Statement, and to cause the Proxy Statement to
be mailed to the Company's stockholders at the earliest practicable date.

     6.8  NOTIFICATION OF CERTAIN MATTERS.  The Company shall give prompt notice
to the Parent and Sub, and the Parent or Sub, as the case may be, shall give
prompt notice to the Company, of (a) the occurrence or non-occurrence of any
event the occurrence, or non-occurrence of which is likely to cause any
representation or warranty of that party in this agreement to be untrue or
inaccurate in any material respect at or prior to the Effective Time and (b) any
failure of that party to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by it under this agreement; PROVIDED,
HOWEVER, that the delivery of any notice pursuant to this section 6.8 shall not
limit or otherwise affect the remedies available under this agreement to any of
the parties receiving such notice.

     6.9  COMPLIANCE WITH ISRA.  The Company has complied or shall comply with
all obligations imposed by the New Jersey Industrial Site Recovery Act ("ISRA"),
all regulations promulgated under ISRA and all directives, orders and
requirements of the New Jersey Department of Environmental Protection ("NJDEP")
issued under ISRA and resulting from this agreement.

     6.10  FEES AND EXPENSES

          (a)  Whether or not the Merger is consummated and except as otherwise
provided in this section 6.10, all costs and expenses incurred in connection
with this agreement and the transactions contemplated by this agreement shall be
paid by the party incurring the expense.

          (b)  The Company agrees to pay the Parent a fee in immediately
available funds equal to $6,000,000 upon the termination of this agreement by
the Parent pursuant to Section 8.1(f) or by the Company pursuant to Section
8.1(g).

     6.11  EMPLOYEE BENEFITS.  The Parent and Sub agree that, for a period of at
least two years following the Effective Time, the Surviving Corporation shall
maintain benefit plans for the employees of the Company and its subsidiaries
with terms that, in the aggregate, are substantially equivalent or better than
those in the benefit plans now in place for such employees, to the extent
permitted under laws and regulations in force from time to time; to the extent
appropriate to carry out the foregoing, the Parent agrees that, following the
Effective Time, employees of the Surviving Corporation shall be eligible to
participate in the Parent's various compensation plans on a basis comparable to
that of similarly situated employees of the Parent and its subsidiaries.


7.   CONDITIONS TO CONSUMMATION OF THE MERGER.  The obligation of each party to
effect the Merger is subject to the satisfaction or waiver, where permissible,
prior to the proposed Effective Time, of the following conditions:

          (a)  unless the Merger is consummated pursuant to section 253 of the

Company and Parent, subject, in the case of the Company, to section 1.4(b);

respect with any of its obligations under this agreement, or any other events or

together with Shares the Company is then required to issue pursuant to
obligations outstanding at that date under employee stock option or other

                             STOCKHOLDERS AGREEMENT


                               DATED JULY 28, 1995

          The parties to this agreement are Schein Pharmaceutical, Inc., a
Delaware corporation (the "Parent"), SM Acquiring Co., Inc., a Delaware
corporation and a subsidiary of the Parent (the "Sub"), and the other parties to
this agreement (each, a "Stockholder", and, collectively, the "Stockholders").

          Simultaneously with the execution and delivery of this agreement and
in reliance on the parties entering into this agreement, the Parent, the Sub and
Marsam Pharmaceuticals, Inc., a Delaware corporation (the "Company"), are
entering into an agreement and plan of merger (the "Merger Agreement"), pursuant
to which the Sub will merge into the Company (the "Merger").  Under the Merger
Agreement, the Parent or Sub will commence a cash tender offer to purchase all
the outstanding shares of common stock of the Company (the "Shares").

          The parties agree as follows:

          1.   TENDER OF SHARES.  Each Stockholder shall validly tender (and not
withdraw) pursuant to and in accordance with the Offer (as defined in the Merger
Agreement), not later than the tenth business day after commencement of the
Offer pursuant to section 1.1 of the Merger Agreement, the number of shares of
common stock of the Company set forth opposite that Stockholder's name on
schedule 1 (the "Existing Shares") beneficially owned by the Stockholder.  Each
Stockholder agrees that the Parent's obligation to accept for payment and pay
for Shares in the Offer is subject to the terms and conditions of the Offer.
The Parent and Sub agree that Shares (as such term is defined in the Merger
Agreement) may not be accepted for payment in the Offer in violation of the
terms of the Merger Agreement.  The Stockholders shall have no obligation under
this section 1 after the earliest of (a) the termination, expiration,
abandonment or withdrawal of the Offer, (b) December 30, 1995 and (c) the
termination of the Merger Agreement in accordance with clause (a), (b), (c),
(d), (e) or (h) of section 8.1 of the Merger Agreement.  In addition, no
Stockholder shall have any obligation under this section 1 in the event that the
Parent has taken any action with respect to or in connection with the Offer
that, pursuant to the provisions of section 1.1(a) of the Merger Agreement, the
Parent is prohibited from taking without the prior written consent of the
Company, unless such Stockholder has given its written consent to such action.

          2.   VOTING OF SHARES.  At any meeting of stockholders of the Company
or in connection with any written consent of

<PAGE>

stockholders of the Company, each Stockholder shall vote (or cause to be voted)
all the Shares beneficially owned by that Stockholder as of the applicable
record date (other than Shares that are not outstanding) (a) in favor of the
Merger, the execution and delivery by the Company of the Merger Agreement and
the approval of the terms of the Merger Agreement; (b) against any action or
agreement that would result in a breach of any agreement of the Company under
the Merger Agreement; and (c) against any other action that could reasonably be
expected to interfere with, delay or otherwise adversely affect the Merger and
the transactions contemplated by the Merger Agreement.  The Stockholders shall
have no obligation under this section 2 or under section 8 after the earlier of
(a) December 30, 1995 and (b) the termination of the Merger Agreement in
accordance with its terms.  In addition, no Stockholder shall have any
obligation under this section 2 or under section 8 following any decrease in, or
change in the form of, the consideration payable to stockholders of the Company
in the Merger, unless that Stockholder shall have given its consent to the
decrease or change.

          3.   OPTIONS

               (a)  Each Stockholder grants the Parent an irrevocable option
(collectively, the "Stock Options") to purchase the number of Shares set forth
opposite that Stockholder's name on schedule 1 (the "Option Shares") at a
purchase price per Share equal to the price per Share payable in the Offer (the
"Purchase Price").  If (a) the Offer is terminated, abandoned or withdrawn by
the Parent or Sub due to the failure of the condition to the Offer set forth in
clause (1) or in sub-clause (C), (D), (F) or (G) of clause (3) of exhibit A to
the Merger Agreement, (b) the Offer is terminated, abandoned or withdrawn by the
Parent or Sub in a circumstance referred to in section 8.1(d) of the Merger
Agreement that involves a suit, action or proceeding by a party that has made an
Acquisition Proposal (as defined in the Merger Agreement) or (c) the Offer is
consummated but the Parent or the Sub has not accepted for payment and paid for
the aggregate number of Shares set forth opposite each Stockholder's name on
schedule 1 and such non-acceptance and non-payment is not in contravention of
the Parent's or Sub's obligations under the Merger Agreement or the Offer, the
Stock Options shall, in each case, become exercisable, in whole but not in part,
upon the first to occur of any such event and remain  exercisable in whole but
not in part until 30 days after the date of the occurrence of that event, as
long as:  (y) all waiting periods under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 (the "HSR Act") required for the purchase of the Option
Shares upon such exercise shall have expired or been waived, and (z) there shall
not be in effect any injunction or other order issued by any court or
governmental, administrative or regulatory agency or authority prohibiting the
exercise of the Stock Options.  If the Parent wishes to exercise

                                        2

<PAGE>

the Stock Options, the Parent shall send a written notice to the Stockholders
identifying the place and date (not fewer than two nor more than 10 business
days from the date of the notice) for the closing of the purchase.
Notwithstanding the foregoing, if the Parent exercises the Stock Options, (i)
the Parent shall, within 30 calendar days after the date of exercise, offer to
all other stockholders of the Company the opportunity to sell their shares of
common stock of the Company to the Parent on the same terms provided in this
section 3 with respect to the purchase of Shares upon the exercise of Stock
Options, subject only to the conditions set forth in clauses (y) and (z) in this
section 3 and in clause (3)(I) of exhibit A to the Merger Agreement, and (ii) if
the amount of cash or fair value of consideration per share paid in that tender
offer or otherwise (including, without limitation, in a merger) for the
acquisition of Shares by the Parent or any of its affiliates (as defined in
section 3(b)) at any time within 183 days after the purchase of Shares pursuant
to the Stock Options exceeds the amount per Share paid upon the purchase of
Shares pursuant to the Stock Options, the Parent shall promptly pay each
Stockholder an amount equal to the product of that excess and the number of
Shares sold by that Stockholder pursuant to the Stock Options.  Anything in this
agreement to the contrary notwithstanding, (i) no Stockholder shall have any
obligation under this section 3(a) if the Stock Options have not been exercised
in accordance with this section 3(a) on or prior to December 30, 1995, and (ii)
no Stock Option may be exercised in respect of the Option Shares of any
Stockholder on or after the date, if any, on which such Stockholder has no
obligation under section 1 of this agreement by reason of the provisions of the
last sentence of section 1 of this agreement.

          (b)  If the Parent purchases Shares pursuant to the Stock Options,
and, at any time(s) within 183 days after the consummation of the purchase, the
Parent or any of its affiliates (as such term is defined in Rule 405 under the
Securities Act of 1933) sells, exchanges or otherwise disposes of any of those
Shares, or agrees to sell, exchange or otherwise dispose of any of those Shares,
voluntarily or otherwise (including, without limitation, pursuant to a merger),
and if the cash or fair value of the consideration per Share received in
exchange exceeds the Purchase Price, then the Parent shall promptly pay or
deliver an aggregate of 60% of that excess to the respective Stockholders pro
rata in relation to the number of Shares sold by them pursuant to the Stock
Options.

          (c)  The Parent shall not offer, sell or otherwise dispose of any
Shares purchased pursuant to the Stock Options in violation of applicable
federal or state securities laws.

          4.   REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDERS.  Each
Stockholder represents and warrants to the Parent as follows:

                                        3

<PAGE>

on schedule 1.  That Stockholder has sole voting power and sole power to issue
instructions with respect to the matters set forth in sections 1 and 2, sole
power of disposition, sole power to demand appraisal rights and sole power to
agree to all  the matters set forth in this agreement, in each case with respect
to all the Existing Shares set forth opposite that Stockholder's name on

encumbrances arising under this agreement.

          (b)  POWER; BINDING AGREEMENT.  That Stockholder has the legal
capacity to enter into and perform all of that Stockholder's obligations under

agreement or voting trust.  This agreement has been duly and validly executed
and delivered by that Stockholder and constitutes a valid and binding obligation
of that Stockholder, enforceable against that Stockholder in accordance with its

insolvency and similar laws affecting creditors' rights generally and subject to
general principles of equity.  There is no other person or entity whose consent
is required for the execution and delivery of this agreement by that Stockholder
or the consummation by that Stockholder of the transactions contemplated by this
agreement.  If that Stockholder is married and that Stockholder's Shares
constitute community property, this agreement has been duly authorized, executed
and delivered by, and constitutes a valid and binding obligation of, that
Stockholder's spouse, enforceable against that spouse in accordance with its
terms, except as enforceability may be limited by applicable bankruptcy,
insolvency and similar laws affecting creditors' rights generally and subject to
general principles of equity.

          (c)  CONSENTS AND APPROVALS; NO VIOLATION.  Assuming the compliance by
the Parent with section 3(c), neither the execution and delivery of this
agreement by that Stockholder nor the consummation by that Stockholder of the
transactions contemplated by this agreement will: (i) require any consent,
approval, authorization or permit of, or filing with or notification to, any
governmental or regulatory authority, except in connection with the HSR Act or
pursuant to the Securities Exchange Act of 1934; (ii) result in a default (or
give rise to a right of termination, cancellation or acceleration) under any of
the terms, conditions or provisions of any note, license, agreement or other
instrument or obligation to which that

                                        4

<PAGE>

Stockholder is a party or by which that Stockholder or any of that Stockholder's

statute, rule or regulation applicable to that Stockholder or by which any of
that Stockholder's assets are bound.

          (d)  BROKERS.  No broker, finder or other investment banker (with the
possible exception of Bear, Stearns & Co. Inc.) is entitled to any broker's,
finder's or other similar fee or commission in connection with this agreement or
the sale of that Stockholder's Option Shares pursuant to this agreement based
upon agreements made by or on behalf of that Stockholder.

give rise to a right of termination, cancellation or acceleration) under any of
the terms, conditions or provisions of any note, license, agreement or other
instrument or obligation to which the Parent is a party or by which the Parent
or any of its assets may be bound; or (iii) violate any order, writ injunction,
decree, statute, rule or regulation applicable to the Parent or by which any of

          6.   NO SOLICITATION.  Prior to December 31, 1995, no Stockholder

notwithstanding, the sole and exclusive remedy for any nonperformance or breach
by any Stockholder or Stockholders of the provisions of this section 6 shall be

attorney with respect to any Shares, the deposit of any Shares into a voting

Gentlemen:

Reference is made to the Stockholders' Agreement (the "Agreement"), dated as of
December 31, 1985, by and among Marsam Pharmaceuticals Inc., Marvin S. Samson,
Agvar Chemicals Inc. and Bolar Pharmaceutical Co., Inc. (now known as Circa
Pharmaceuticals, Inc.) Marsam is contemplating a transaction pursuant to which a
third party will make an offer to all of the Marsam stockholders to purchase
their Marsam shares on the same terms and conditions and Agvar and Samson are
granting an option (including an option to tender) to the third party to
purchase their Marsam shares exercisable under certain circumstances. This
letter, when executed on behalf of the parties hereto in the spaces provided
below, will evidence each party's waiver or any rights that it otherwise would
have had under the Agreement in respect of all the transactions referred to
above, and except as set forth herein, the Agreement shall remain in full force
and effect until December 31, 1995.

                                        Very truly yours,

                                        MARSAM PHARMACEUTICALS INC.

                              EMPLOYMENT AGREEMENT



          AGREEMENT dated as of July 28, 1995 by and between MARSAM
PHARMACEUTICALS INC., a Delaware corporation having its principal office at
Building 31, Olney Avenue, Cherry Hill, New Jersey (the "Company"), and Marvin
S. Samson, residing at 1905 Owl Court, Cherry Hill, New Jersey 08003 (the
"Executive").

          The parties are entering into this Agreement to set forth and confirm
their respective rights and obligations with respect to Executive's employment
by the Company.

          NOW, THEREFORE, in consideration of the mutual covenants herein
contained, the parties hereto mutually agree as follows:

          1.  EMPLOYMENT AND TERM.  (a) The Company hereby employs the Executive
as president, chief executive officer and chief operating officer of the Company
and, as of the Acquisition Date, the Executive shall be appointed an Executive
Vice President of Schein Pharmaceutical, Inc., a Delaware corporation ("SPI")
(collectively, the "Position").  The Executive agrees to serve in the employ of
the Company in the Position for a term (the "Initial Term") which shall commence
on the date of the acquisition by SPI or a subsidiary of SPI of more than a
majority of the outstanding shares of the common stock of the Company on a
fully-diluted basis (the "Acquisition Date"), and, subject to paragraphs 1(b)
and 1(c) hereof, shall terminate on the fifth anniversary of the Acquisition
Date.

               (b)  Unless written notice terminating the term of employment is
given by either the Company or the Executive not less than one hundred eighty
(180) days in advance of the termination date of this Agreement, this Agreement
shall be automatically extended, on all of the terms and conditions hereof, for
additional periods of one-year.

               (c)  The Company shall have the right to terminate the
Executive's employment hereunder prior to the fifth anniversary of the
Acquisition Date, but only for cause.  For purposes of this Agreement, "cause"
means (i) the Executive's willful and continued failure substantially to perform
his duties with the Company or SPI, (ii) fraud, misappropriation or intentional
material damage to the property or business of the Company or SPI or (iii) the
Executive's admission or conviction of, or plea of nolo contendere to, any
felony that, in the judgment of the Board of Directors of the Company (the
"Board"),

<PAGE>

adversely affects the Company's reputation or the Executive's ability to carry
out his obligations under this Agreement.  The Executive shall not be entitled
to any compensation under this Agreement for any period after such termination
pursuant to this paragraph 1(c) except to the extent the Executive is entitled
to receive benefits under the Plans (as defined herein) following such
termination.

               (d)  The Executive shall have the right to terminate his
employment hereunder at any time prior to the fifth anniversary of the
Acquisition Date.

               (e)  Anything in this Agreement to the contrary notwithstanding,
the Company, at its option, may retain the Executive as a consultant for a
period (the "advisory period") of one year after (i) the Initial Term (or any
extension under paragraph 1(b) hereof) or (ii) a termination by the Executive
pursuant to paragraph 1(d) hereof, all on the terms and conditions hereinafter
provided, in which event, the Executive shall continue to be bound by the
restrictions of paragraph 7(b) hereof during the advisory period, as if he were
an employee for such period.  During the advisory period, the Executive will
provide such advisory services concerning the business, affairs and management
of the Company as may be from time to time requested by the Company, but the
Executive shall not be required to devote more than five (5) days (up to an
aggregate of forty (40) hours) each month to such services, which shall be
performed at a time mutually convenient to both parties.  The Company, at its
option, may terminate the advisory period upon not less than thirty (30) days'
prior written notice; PROVIDED, that upon termination of the advisory period,
the Executive shall no longer be bound by the restrictions of paragraph 7(b)
hereof.  The Executive may, subject to the restrictions set out in paragraph
7(b) hereof, engage in other employment during the advisory period, and his
advisory services hereunder shall be required only at times and places
consistent with his other employment and his private activities.  During the
advisory period, the Company shall pay the Executive a consulting fee in an
amount equal to the Executive's base salary immediately prior to the termination
of employment, payments of such fee to be made in accordance with the Company's
standard payroll policies in effect from time to time, and provide the Executive
and his eligible dependents with health insurance coverage and disability
insurance coverage for the Executive comparable to coverage while he was an
employee hereunder or, at the Company's option, reimburse the Executive in an
amount equal to not more than 125% of the cost to the Company thereof while an
employee during the previous year; PROVIDED, HOWEVER, that, should the Executive
engage in other employment, such consulting fee shall be reduced, on a dollar-
for-dollar, basis, by an amount equal to the compensation received by the
Executive for such other employment; and the consulting fee shall be reduced, on
a dollar-for-dollar basis, by compensation paid to the Executive by the Company
under paragraph 3(d) hereof for the

                                        2

<PAGE>

same period of time.  Without limiting the application of any other provision of
this Agreement during the advisory period, the Company expressly confirms that
the provisions of paragraph 4 hereof shall apply during the advisory period.

          2.  DUTIES.  (a)  Subject to the ultimate control and discretion of
the Board, the Executive shall serve in the Position and perform all duties and
services of an executive nature commensurate with the Position which the Board
may from time to time reasonably assign to him.  Except for travel normally
incidental and reasonably necessary to the business of the Company and the
duties of the Executive hereunder, the duties of the Executive shall be
performed in the Cherry Hill, New Jersey area.  SPI shall also make available to
the Executive an office for his use in its corporate headquarters.

               (b)  The Executive shall, consistent with his position as
president and chief executive officer of the Company and executive vice
president of SPI, be responsible for the management of the Company and its
organizational structure, subject to the Board and to the provisions of this
Agreement, his authority to include, without limitation, supplier relationships
and salary, perquisites and, with respect to stock options, (subject
additionally to SPI's Board of Directors) stock options for SPI common stock for
the Company's employees.

               (c)  The Executive shall, consistent with his position as
president and chief executive officer of the Company and executive vice
president of SPI, be responsible for, and shall co-ordinate, all product
development activities for SPI's and the Company's parenteral products.

               (d)  The Executive shall, consistent with his position as
president and chief executive officer of the Company and executive vice
president of SPI, be responsible for and shall co-ordinate, all sales and
marketing activities for SPI's and the Company's hospital and home care
accounts.

               (e)  The Executive shall devote all of the Executive's time and
attention during regular business hours to the performance of the Executive's
duties hereunder and, during the term of his employment hereunder, shall not
engage in any other business enterprise which requires the Executive's personal
time or attention, unless granted the prior permission of the Board.  The
foregoing shall not prevent the Executive's purchase, ownership or sale of any
interest in, or the Executive's engaging (but not to exceed an average of five
hours per week) in, any business which does not compete with the business of the
Company or SPI or any subsidiary of the Company or SPI or the Executive's
involvement in charitable or community activities, provided, that the time and
attention which the Executive devotes to such business and activities does not
materially interfere with the performance of his duties hereunder.

                                        3

<PAGE>

               (f)  The Executive shall be entitled to such personal vacations
with full compensation, and to be taken at such time or times, as the Executive
and the Company shall mutually determine.

          3.  COMPENSATION.  (a)  For all services to be rendered by the
Executive hereunder, the Company shall pay the Executive an annual salary at a
rate of not less than Four Hundred Thousand Dollars ($400,000) per year, plus
such other compensation as may, from time to time, be determined by the Company.
Such salary and other compensation shall be payable in accordance with the
Company's normal payroll practices as in effect from time to time.  At the end
of each fiscal year, the Company shall review the Executive's salary level, and
shall increase such level for the following year to such amount as the Board may
determine.

               (b)  The compensation provided for in paragraph 3(a) above shall
be in addition to such rights as the Executive may have, during the Executive's
employment hereunder or thereafter, to participate in and receive benefits from
or under any bonus, stock option, pension, profit-sharing, insurance or other
employee benefit plan or plans of the Company which may exist now or hereafter
(collectively, the "Plans").  During the period ending on the first anniversary
of the Acquisition Date, the Executive shall have the right, on a basis
reasonably acceptable to the Company and SPI (such acceptance not to be
unreasonably withheld), to elect to participate (with credit to the greatest
extent possible for prior years of service with the Company), to the extent he
is eligible, and subject to applicable law, in one or more SPI benefit plans in
which senior executives of SPI participate, in lieu of one or more Company
benefit plans relating to the same type of benefit.

               (c)  If the Company terminates the Executive's employment
hereunder, other than in accordance with paragraph 1(c) above, the Company shall
continue to pay the Executive the salary provided in paragraph 3(a) above, in
accordance with the Company's normal payroll practices in effect from time to
time, and provide the Executive and his eligible dependents with health
insurance coverage and disability insurance coverage comparable to coverage
while he was an employee hereunder or, at the Company's option, reimburse the
Executive in an amount equal to not more than 125% of the cost to the Company
thereof while an employee during the previous year, all for the remainder of the
Initial Term or any extension thereof; and the Executive shall have no further
or other rights, and the Company no further or other liabilities or obligations,
under this Agreement.

               (d)  If the Executive terminates his employment hereunder prior
to the end of the Initial Term under paragraph 1(d) above, the Company shall
continue to pay the Executive 50% of the salary provided for in paragraph 3(a)
above, in accordance with the Company's normal practices in effect from time to
time,

                                        4

<PAGE>

and provide the Executive and his eligible dependents with health insurance
coverage and disability insurance coverage comparable to coverage while he was
an employee hereunder or, at the Company's option, reimburse the Executive in an
amount equal to not more than 125% of the cost to the Company thereof while an
employee during the previous year, all for a period beginning on the date of
such termination and ending on the earlier of the third anniversary of the
termination or the fifth anniversary of the Acquisition Date; and the Executive
shall have no further or other rights, and the Company no further or other
liabilities or obligations, under this Agreement.

               (e)  During any period in which the Company is obligated to pay
salary to the Executive under this paragraph 3 or a consulting fee under
paragraph 1(e) of this Agreement, the Company shall provide the Executive with
an automobile or, at the Company's option, an automobile allowance, in
accordance with the Company's policies in effect from time to time.

          4.  EXPENSES.  The Company shall promptly reimburse the Executive, or
cause the Executive promptly to be reimbursed, for all reasonable expenses paid
or incurred by the Executive in connection with the performance of the
Executive's duties and responsibilities hereunder, upon presentation of expense
vouchers or other appropriate documentation therefor.

          5.  ADDITIONAL COVENANTS.  During the Executive's employment under
this Agreement, except as otherwise consented to or approved by the Executive
and SPI:

               (a)  (1)  the Board will be comprised of seven members, three to
be designated by the Executive, three to be designated by SPI (the "SPI
directors") and one, who shall be an employee of Bayer Corporation or any of its
affiliates (other than SPI and its subsidiaries), to be designated by SPI,

                      COMPENSATION CONTINUATION AGREEMENT


     AGREEMENT made this 19th day of October, 1991, by and between MARSAM
PHARMACEUTICALS INC., a Delaware corporation ("Company") and MARVIN SAMSON,
1905 Owl Court, Cherry Hill, New Jersey ("Employee").

                                  BACKGROUND

     Employee is, and since the Company's inception in 1985 has been, chief
executive officer and a key employee of the Company. Employee and the Company
entered into an Employment Agreement dated as of December 19, 1986, which has
been amended to extend its term to December 31, 1996, and year to year
thereafter (the "Employment Agreement")>

     The continued services of Employee and his knowledge of the Company's
activities and of the industry in which the Company participates are of great
value to the Company. The Company believes that it is in its best interests
to provide Employee with the security of a level of continuing payments to
Employee or Employee's designee in the event of his retirement, disability or
death.

     NOW, THEREFORE, intending to be legally bound hereby, the Company and
Employee agree as follows:

     1.  TERM OF AGREEMENT.  This Agreement shall remain in effect and confer
upon Employee the benefits set forth herein so long as Employee's employment
by the Company is not terminated by the Company based upon a clear showing of
due

<PAGE>

cause, as hereinafter defined, and with Employee first having had a reasonable
opportunity to cure. Termination of Employee's employment by the Company shall
be for due cause hereunder in the event that the termination is in connection
with (i) any dishonest action against the Company, (ii) admission or conviction
of any fraud or embezzlement, or (iii) a breach or violation by Employee during
his employment of the confidentiality or non-competition covenants set forth in
paragraph 6 of the Employment Agreement.

     2.  RETIREMENT.  In the event of the Employee's retirement, as
hereinafter defined, the Company shall pay to the Employee in the first
year following commencement of retirement an amount equal to Employee's
annual base salary immediately prior to his retirement and, thereafter, fifty
percent (50%) of such amount for each of the next nine years. In the event of
Employee's death after his retirement, there shall be a continuation of the
retirement payments for a period of ten (10) years from the commencement of
Employee's retirement, with the payments after death being made to the
beneficiary designated by Employee. All payment obligations under this
agreement shall be met by periodic payments on the same dates as executive
compensation is paid by the Company, except as otherwise agreed by the
parties.

                                     -2-

<PAGE>

     3.  DEFINITION OF RETIREMENT.  Employee may elect to retire by giving
written notice of such election to the Company not less than ninety (90) days
prior to the proposed commencement of retirement, but in no event shall such
retirement be effective prior to the end of Employee's employment term under
the Employment Agreement or any agreement superseding or extending the
Employment Agreement. Furthermore, for the purposes of paragraph 2 hereof,
termination of Employee's employment as the result of either party giving
notice of termination pursuant to paragraph 1(b) of the Employment Agreement
shall be deemed to be Employee's retirement hereunder. The retirement
payments provided for herein shall be made on the same dates as those on
which the Company makes compensation payments to executive employees
generally.

     4.  DISABILITY.  If Employee, while employed by the Company, becomes
unable, for a period of six (6) months during any period of twelve (12)
consecutive months, to perform his duties due to partial or total disability
or incapacity resulting from a mental or physical illness or injury, as
certified by a licensed physician, the Company shall make disability payments
to Employee until the earlier of resumption of employment or the end of the
year in which Employee reaches age sixty-five (65), in an amount equal to
Employee's annual base salary immediately prior to commencement of Employee's
disability for the first year of disability, and

                                     -3-
<PAGE>

fifty percent (50%) of said amount in each of the years following. The
disability payments provided for herein shall be reduced to the extent of
payments received by Employee from any disability benefit program arranged
and paid for by the Company, and any fees or other payments by the Company
for services provided by Employee. Upon reaching age 65, Employee, if
disabled, shall be deemed to have retired for purposes of paragraph 2 hereof
and shall be entitled to retirement benefits equal to fifty percent (50%) of
Employee's annual base salary immediately prior to commencement of Employee's
disability in accordance with said paragraph 2.


     5.  OTHER INSURANCE BENEFITS.  During the period of retirement or
disability payments under this Agreement, the Company shall continue to
provide Employee with health and medical insurance coverage and benefits to
the same extent as if he had continued to be an executive employee of the
Company.

     6.  DEATH.  In the event of Employee's death while still in the employ of
the Company, the Company shall pay to Employee's designee during the first
year after death an amount equal to Employee's annual base salary immediately
prior to his death and, thereafter, fifty percent (50%) of said amount for
each of the next nine (9) years. In the event of Employee's death while
entitled to disability payments pursuant to paragraph 4 hereof, the Company
shall pay to Employee's designee an amount equal to fifty percent (50%) of
Employee's annual base salary immediately prior to the commencement of
Employee's disability during each of the next nine (9) years.

                                     -4-
<PAGE>

     7.   RESTRICTIVE COVENANT. Notwithstanding the time limits set forth in
paragraph 6 of the Employment Agreement (or comparable provisions of any
agreement superseding or extending the Employment Agreement) with respect to
Employee's obligations to maintain confidentiality and not compete with the
Company, the payment obligations of the Company under paragraphs 2, 4 and 6
hereof shall cease if the Company, after notice to Employee of its intent to do
so, obtains a judicial determination that Employee's conduct is in violation of
the provisions of the Employment Agreement respecting confidentiality and
noncompetition, or would be in the absence of the time limitation provisions
applicable to such provisions.

     8.   BINDING EFFECT. This Agreement will be binding on the Company and the
Employee, their heirs, legal representatives, successors and assigns.

     9.   GOVERNING LAW. This Agreement shall be deemed to be executed,
delivered and is intended to be performed in the State of New Jersey and in all
respects is to be governed by the laws of the State of New Jersey.

     10.  SEVERANCE.  In the event that performance of any provision hereunder
shall in any way be in contravention of any law, rule or regulation of any
governmental body claiming to have jurisdiction, then, to the extent of such
illegality or violation, this Agreement shall be inoperative without in any
manner impairing its other provisions and obligations.

     11.  UNFUNDED ARRANGEMENT. The Company shall pay the benefits provided
hereunder out of its general assets in cash

                                     -5-

<PAGE>


when due. The Company shall not be required to establish any segregated account,
trust, escrow, reserve or other arrangement to discharge such benefits. No asset
of the Company shall be deemed segregated or otherwise set aside to discharge
the Company's obligations under this agreement. The rights and benefits of the
Employee or any beneficiary thereof shall be solely those of an unsecured
general creditor.

     12.  NON-ALIENATION.  None of the payments, benefits or rights of the
Employee or beneficiary thereof shall be subject to any claim of any creditor of
such person and, in particular, to the fullest extent permitted by law, shall be
free from attachment, garnishment, trustee's process, or any other legal or
equitable process available to any creditor of such person. The Employee or
beneficiary thereof shall not have the right to alienate, anticipate, commute,
pledge, encumber or assign any of the benefits or payments which he may expect
to receive, contingently or otherwise, under this agreement, except the right to
designate a beneficiary or beneficiaries as hereinabove provided.

     13.  EMPLOYMENT OBLIGATIONS. This agreement shall not be construed as
creating any additional contract of employment between the Company and the
Employee or as giving the Employee, or any person whomsoever, any legal or
equitable rights against the Company unless such rights shall be specifically
provided for in this agreement or conferred by affirmative action of the Company
in accordance with the terms and provisions of this agreement.

                                     -6-
<PAGE>

     14.  TAXES. The Company shall not be responsible for the tax consequences
under federal, state or local law of the Employee under this agreement. All
payments under this agreement shall be subject to withholding and reporting
requirements to the extent provided by applicable law.

     IN WITNESS WHEREOF, the Company has caused this Agreement to be executed by
its duly authorized officer, and the Employee has executed this Agreement, each
as of the day and year first above written.

surrender of the Policy directly from the Insurer.

     2.   The Insurer is authorized to rely solely on the written statement of
the Company and the Owner for the exercise of any rights under the Policy
