     "NOLs"), and the purchase of the Shares at the Closing and the exercise of
     the Warrant or the Additional Warrant, assuming they were issued and
     exercised at the Closing, will not cause such "ownership change" or any
     limitation on the NOLs.

     consent describing in reasonably detail the nature and substance of such
     action;

          (v) such observer shall be bound by the confidentiality provisions set
     forth in Section 6.2 hereof,  but such provisions shall not prohibit or
     restrict such observer from disclosing or providing any information of any

interest in any Pharmaceutical Opportunity pursuant to Section 9.1 hereof, the
Company shall be entitled to participate in any sale or other disposition by the
Purchaser or its Affiliates of any of their interests in such Pharmaceutical
Opportunity by selling the same proportionate part of the Company's interest in
such Pharmaceutical Opportunity, at the same price and on the same terms and
conditions, as proposed to be sold by the Purchaser or such Affiliates.  The
Purchaser shall give the Company at least 30 days prior written notice of any
proposed sale or other disposition, and the Company shall notify the Purchaser,

same terms and conditions as specified in such Transaction Notice.  As a
condition to exercising its right in this Section 10.1, the Purchaser shall (i)
deliver with its notice an opinion of Wertheim Schroder & Co. (or an investment
bank of similar or greater standing and reputation which shall have significant
operations in the United States) addressed to the Company's Board of Directors
to the effect that the type and amount of consideration offered by the Purchaser
in its notice is equivalent to the type and amount of the consideration being
paid in the Third Party Transaction and (ii) demonstrate to the reasonable
satisfaction of the Company that the Purchaser has the financial ability and
resources to consummate the transaction contemplated in the Purchaser's notice.
The cost of such opinion shall be paid equally by the Purchaser and the Company.
In the event that the Purchaser shall not provide notice of its election to
consummate such transaction within such 60-day period, the Company may
consummate such Third Party Transaction on substantially the same terms and
conditions as specified in the Transaction Notice at any time within 180 days
after the expiration of such 60-day period.  If the Company shall not consummate
such Third Party Transaction within such period, the consummation of such
Transaction or any other Third Party Transaction shall again be subject to the
Purchaser's rights under this Section 10.1(a).

          (b) The closing of any transaction to be consummated with the
Purchaser pursuant to this Section 10.1 shall take place at the offices of the

                                                                              22

equity interests in, the resulting entity, (ii) sell an amount of its securities
which, as a result of such transaction, would cause such third party to own,
beneficially, 51% or more of the outstanding voting securities of the Company or
(iii) sell all or substantially all of its assets.

          (d) Notwithstanding anything to the contrary contained herein, the
Purchaser shall only be entitled to exercise its right of first refusal pursuant
to Section 10.1(a) hereof if, at the time of exercise of such right of first
refusal, (i) the Purchaser shall not have previously sold, transferred or
otherwise disposed of (in a transaction or series of transactions) more than the
sum of 334,778 shares of Common Stock plus 2% of any additional shares of Common
Stock issued after the date hereof and prior to the Closing and (ii) either (A)
the Warrant or the Additional Warrant shall be outstanding or (B) the Purchaser
shall own of record 14% (subject to Section 7.7(b) hereof) of the issued and
outstanding shares of Common Stock.

          (e) If the Company shall consummate a Third Party Transaction as to
which the Purchaser did not exercise, for any reason, the right of first refusal
pursuant to Section 10.1(a) hereof, the Purchaser shall have no further rights
under said Section 10.1(a) with respect to any future Third Party Transactions.

          10.2 Purchaser's Voting Obligations.  (a) The Purchaser shall, during
               ------------------------------

terminate under Section 10.1 hereof, vote all shares of Common Stock owned or
held by it in favor of a Third Party Transaction (other than a Third Party
Transaction as to which the Purchaser shall have exercised its right under
Section 10.1 hereof) with respect to which a vote of the Company's stockholders
shall be taken, and shall take such other actions (including, without
limitation, surrendering its shares of Common Stock and the Warrant and the
Additional Warrant, if issued) reasonably required or appropriate to facilitate
the consummation of such Transaction.

          (b) Notwithstanding the foregoing, the Purchaser shall not be required
to vote its shares of Common Stock in favor of, or take other actions to
facilitate, such Third Party Transaction if (i) less than 75% of the members of
the Company's Board of Directors (exclusive of those members appointed by the
Purchaser pursuant to Section 7.2 hereof) shall have voted in favor of such
Transaction or (ii) any member of the Board (other than any member appointed by
the Purchaser pursuant to Section 7.2 hereof) shall have voted against such
Transaction, regardless of how many directors

 
                                                                              23

voted in favor of such Transaction.  Furthermore, in the event that the
Purchaser shall notify the Company that, in the opinion of the Purchaser, the
consummation of the Third Party Transaction would be detrimental to the Company
and/or its stockholders, the Purchaser shall not be required to vote its shares
of Common Stock in favor of, or take other actions to facilitate, such Third
Party Transaction unless the Company, in response to the Purchaser's notice,
shall have delivered, at the Company's cost, to the Purchaser a fairness opinion
with respect to such Third Party Transaction from a nationally recognized
investment banking firm selected by the Company.

               -----------------------------------------                        
("Consent Period") commencing on the Closing Date and terminating six months
after the date on which the Purchaser's rights shall terminate under Section
10.1 hereof, the Purchaser shall not sell, assign, pledge, transfer or otherwise
dispose of (collectively, a "Transfer") any Securities (as hereinafter defined)
without the written consent of the Company (which may be granted or withheld in
its sole discretion) unless such Securities (i) shall be registered under the
Securities Act and applicable state securities laws, (ii) shall be sold in
brokers' transactions pursuant to Rule 144 promulgated under the Securities Act
or (iii) shall be sold or transferred in connection with a Third Party
Transaction or any other transaction that has been approved by a majority of the
members of the Board (exclusive of those members appointed by the Purchaser
pursuant to Section 7.2 hereof).  For the purposes hereof, "Securities" shall
mean and include the Shares, the Warrant Shares, the Additional Warrant Shares,
if issued, any other shares of Common Stock, and any rights, options, warrants
or other securities of the Company exercisable or exchangeable for, or
convertible into, shares of Common Stock.

          (b) Except as permitted by Section 16.2 hereof, the Purchaser, during
the Consent Period, shall not sell, transfer or otherwise dispose of any shares
of Common Stock, constituting 3% or more of the issued and outstanding shares
of Common Stock at the time of such sale, transfer or disposition to any one
person or entity or group of related persons or entities in one transaction or
series of related transactions, notwithstanding anything to the contrary
contained herein.

 
                                                                              24

          (c) At any time or from time to time subsequent to the Consent Period,
the Purchaser shall not transfer any Securities unless such Transfer shall be in
full compliance with all applicable provisions of the Securities Act and all
applicable provisions of state securities laws.

          (d) Each certificate for the Shares, the Warrant Shares and the
Additional Warrant Shares shall be endorsed with the following legend:

     "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933 OR UNDER ANY STATE SECURITIES LAWS, AND MAY NOT BE
     SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF
     EFFECTIVE REGISTRATION STATEMENTS UNDER APPLICABLE FEDERAL AND STATE
     SECURITIES LAWS OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT
     THE TRANSFER IS EXEMPT FROM REGISTRATION UNDER APPLICABLE FEDERAL AND STATE
     SECURITIES LAWS.  THE SECURITIES REPRESENTED HEREBY ARE ALSO SUBJECT TO
     LIMITATIONS ON TRANSFER PURSUANT TO A STOCK PURCHASE AGREEMENT DATED MARCH
     25, 1995, BETWEEN THE COMPANY AND THE HOLDER HEREOF (A COPY OF WHICH IS ON
     FILE AT THE OFFICES OF THE COMPANY)."

          11.2 Limitations on Acquisitions of the Company's Securities.  (a)
               -------------------------------------------------------      
During the Consent Period, the Purchaser shall not purchase or otherwise acquire
any additional Securities without the prior written consent of the Company
(which may be granted or withheld in its sole discretion), except for (i)
acquisitions of the Warrant Shares or the Additional Warrant Shares, (ii)
acquisitions of Securities pursuant to subdivisions (b) and (c) of this Section
11.2, (iii) acquisitions of Securities pursuant to Sections 11.3 and 11.4(b)
hereof and (iv) acquisitions of Securities pursuant to Section 9.4 hereof.

          (b) The Purchaser, at any time after the Closing Date, shall be
entitled, upon at least 24 hours' prior written notice to the Company, to
purchase or acquire, in open market transactions, such number of Securities as
will cause the Purchaser to own up to 19.99% of the then issued and outstanding
shares of the Common Stock (assuming, for this purpose, the exercise, exchange
or conversion, as applicable, of such Securities into shares of Common Stock).
Upon the acquisition of any such Securities by the Purchaser, the aggregate
number of Warrant Shares and Additional Warrant Shares issuable upon exercise of
the Warrant or the Additional Warrant shall, as of the date of such acquisition,
be reduced, on a share for share basis, in an amount equal to the number of
shares of Common Stock acquired by the Purchaser (including, for this purpose,
shares of Common Stock issuable upon any exercise, exchange

 
                                                                              25

or conversion of the Securities), with any such reduction first being applied
against the Warrant Shares and, thereafter, being applied against the Additional
Warrant Shares; provided, that, prior to the issuance of the Additional Warrant,
                --------  ----                                                  
no such reduction shall occur unless the sum of the shares of Common Stock owned
by the Purchaser plus the Warrant Shares equals 19.99% of the then issued and
outstanding shares of Common Stock (assuming, for this purpose, exercise of the
Warrant in full).

          (c) The Purchaser, subsequent to the third anniversary of the Closing
Date, shall be entitled, upon at least 24 hours' prior written notice to the
Company, to purchase or acquire, in open market transactions, such number of
Securities as will cause the Purchaser to own up to 25% of the then issued and
outstanding shares of the Common Stock (assuming, for this purpose, the
exercise, exchange or conversion, as applicable, of such Securities into shares
of Common Stock).

          11.3 Public Offerings.  The Purchaser, after the Closing, shall be
               ----------------                                             
entitled to acquire up to 20% of any Securities to be issued by the Company in
an underwritten public offering registered pursuant to the Securities Act on the
same terms and conditions, including the same price per share, as such
Securities shall be sold in such offering.  If the Purchaser shall elect to
exercise such right, the Purchaser shall give notice to the Company of the
number of shares to be acquired by the Purchaser, within 15 days after receipt
of a notice from the Company describing the terms and conditions of the proposed
offering.  The Purchaser shall not be entitled to exercise its right under this
Section 11.3 unless, at the time, the Purchaser shall own shares of Common Stock
(including, for this purpose, Warrant Shares then issuable upon exercise of the
Warrant and the Additional Warrant Shares then issuable upon exercise of the
Additional Warrant, if issued) at least equal to 10% of the sum of (i) the
number of issued and outstanding shares of Common Stock, (ii) the number of
Warrant Shares then issuable upon exercise of the Warrant and (iii) if issued,
the Additional Warrant Shares then issuable upon exercise of the Additional
Warrant.

          11.4 Standstill.  (a)  During the Consent Period, the Purchaser shall
               ----------                                                      
not, without the prior approval of a majority of the Company's Board of
Directors (exclusive of members appointed by the Purchaser pursuant to Section
7.2 hereof), enter into any agreement or arrangement with any person or entity
(other than the Company) concerning the voting, holding or transferring of any
Securities, or initiate, propose or participate in any transaction involving the
Company (including, without limitation, any

 
                                                                              26

purchase of, or tender for, any Securities or any purchase of the Company's
assets), except as otherwise provided in Section 11.4(b) hereof.

          (b) Nothing contained herein shall prohibit the Purchaser, subsequent
to the fifth anniversary of the Closing Date, to tender for, and/or purchase or
otherwise acquire, such number of shares of Securities as would cause the
Purchaser to own at least 70% of the issued and outstanding shares of Common
Stock.  Notwithstanding the foregoing, the Company shall have no obligation to
support, or otherwise cooperate with, the Purchaser or any of its Affiliates in
any such tender offer or acquisition of Securities, and the Company, in no
event, shall be required to make any favorable recommendation in furtherance of
such tender offer or such acquisition.

          SECTION 12.  Exchanges; Lost, Stolen or Mutilated Certificates.
                       -------------------------------------------------  
Subject to Section 11 hereof and upon surrender by the Purchaser to the Company
of any certificates representing the Shares, the Warrant Shares or the
Additional Warrant Shares, the Company, at its expense, shall issue in exchange
therefor, and deliver to the Purchaser, a new certificate or certificates
representing such Shares, Warrant Shares or Additional Warrant Shares, in such
denominations as may be requested in writing by the Purchaser.  Every
surrendered certificate representing the Shares, the Warrant Shares or the
Additional Warrant Shares shall be duly endorsed or be accompanied by a written
instrument of the Purchaser's attorney duly authorized in writing.  Upon receipt
of evidence satisfactory to the Company of the loss, theft, destruction or
mutilation of any certificate representing any Shares, Warrant Shares or
Additional Warrant Shares, and in case of any such loss, theft or destruction,
upon delivery of an indemnity agreement satisfactory to the Company, or in case
of any such mutilation, upon surrender and cancellation of such certificate, the
Company shall issue and deliver to the Purchaser a new certificate for such
Shares, Warrant Shares or Additional Warrant Shares of like tenor and in the
same amount and name, in lieu of such lost, stolen or mutilated certificate.

          SECTION 13.  Survival of Representations, Warranties and Agreements.
                       ------------------------------------------------------- 
All representations and warranties of the parties hereunder shall survive the
Closing.  Except as otherwise provided herein, all covenants and agreements of
the parties contained herein shall survive indefinitely until, by their
respective terms, they shall no longer be operative.

 
                                                                              27

          SECTION 14.  Disclosure of Documents.  The Company represents to the
                       ------------------------                               
Purchaser that, to the best of the Company's knowledge, there are no documents
which contain information materially adverse to the Company that have not been
disclosed in the documents set forth on Exhibit D annexed hereto (to the extent
supplemented by the Company as provided herein) or in publicly available
documents filed with the SEC or issued in public press releases.  Set forth in
Exhibit D is an itemized list, prepared by the Purchaser, of documents made
available to the Purchaser and/or its representatives (including its attorneys,
its accountants and its regulatory advisor) for review.  The Company shall have
the right to supplement Exhibit D up to five days prior to the Closing by making
additional documents available to Purchaser for its review.  In the event that
the Company provides any such additional document and that document contains
information materially adverse to the Company, which information was not
previously disclosed in the documents set forth in Exhibit D or in publicly
available documents filed with the SEC or issued in public press releases, then
the Purchaser shall (with respect to each such document) have the right
(exercisable by written notice to the Company within five days after the
Purchaser's receipt of such document) to elect not to consummate the
transactions contemplated by this Agreement, in which case neither party shall
have any liability or obligation to the other hereunder and this Agreement shall
terminate.

          SECTION 15.  Indemnification.
                       --------------- 

          15.1 Indemnitors; Indemnified Persons.  For purposes of this Section
               --------------------------------                               
15, each party which, pursuant to this Section 15, agrees to indemnify any other
person or entity shall be referred to, as applicable, as the "Indemnitor" with
respect to such persons and entities, and each such person and entity who is
indemnified shall be referred to as the "Indemnified Person" with respect to
such Indemnitor.

          15.2 Company Indemnity.  The Company hereby agrees to indemnify and
               -----------------                                             
hold harmless each of the Purchaser, and its directors, officers, employees,
agents and controlling persons (within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act), from and against any and
all claims, liabilities, losses, damages and expenses (including, without
limitation, reasonable attorneys' fees and disbursements, regardless of whether
incurred in connection with a third-party claim) asserted against or incurred by
any such Indemnified Person which are caused by or are related to or arise out
of (a) any breach of any representation, warranty, covenant or agreement of the
Company contained in this Agreement, the Warrant, the Additional Warrant or the
Registration Rights Agreement or

 
                                                                              28

(b) (i) any violation by the Company or any subsidiary thereof, or their non-
compliance with, any Environmental Law (as defined below), or the disposal,
discharge or release of solid wastes, pollutants or hazardous substances,
whether in compliance with Environmental Laws or not, (ii) the ownership,
operation or use of any landfill, wastewater treatment plant, air pollution
control equipment, storage lagoon or other waste management or pollution control
facility, whether in compliance with Environmental Laws or not, or (iii)
exposure of any person to any chemical substances, noises or vibration generated
by the Company, any of its subsidiaries, or any of their respective
predecessors, whether in compliance with Environmental Laws or not; provided,
                                                                    --------

diminution in the value of the shares of Common Stock owned by the Purchaser.
The Company shall reimburse any such Indemnified Person for all costs and
expenses (including, without limitation, reasonable attorneys' fees and
disbursements), as they shall be incurred, in connection with investigating,
preparing for, or defending any action, claim, investigation, inquiry or other
proceeding, whether or not in connection with pending or threatened litigation,
which are caused by or related to or arise out of the foregoing, whether or not
such Indemnified Person shall be named as a party thereto and whether or not any
liability shall result therefrom.  For purposes of this Section 15.2,
"Environmental Law" shall mean any law, regulation, rule or requirement (whether
existing now or in the future) of the United States, any other country or any
state, province, municipality or other subdivision thereof relating to the
pollution or protection of the environment (including, without limitation,
ambient air, surface waters, ground water, lands, sub-surface strata, biota and
cultural properties), and any permit, licensed or registration issued pursuant
to any of the foregoing notwithstanding anything herein to the contrary.

          15.3 Purchaser Indemnity.  The Purchaser hereby agrees to indemnify
               -------------------                                           
and hold harmless each of the Company, and its directors, officers, employees,
agents and controlling persons (within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act), from and against any and
all claims, liabilities, losses, damages and expenses (including, without
limitation, reasonable attorneys' fees and disbursements, regardless of whether
incurred in connection with a third-party claim) asserted against or incurred by
any such Indemnified Person which are caused by or are related to or arise out
of the Purchaser's breach of any representation, warranty, covenant or agreement
of the Purchaser contained in this Agreement, the Warrant, the Additional
Warrant or the Registration Rights Agreement, and shall reimburse any such
Indemnified Person

 
                                                                              29

for all costs and expenses (including, without limitation, reasonable attorneys'
fees and disbursements), as they shall be incurred, in connection with
investigating, preparing for, or defending any action, claim, investigation,
inquiry or other proceeding, whether or not in connection with pending or
threatened litigation, which shall be caused by or related to or arise out of
such breach, whether or not such Indemnified Person shall be named as a party
thereto and whether or not any liability shall result therefrom.

          15.4 Defense.  Promptly after receipt by an Indemnified Person of
               -------                                                     
notice of any claim or demand or the commencement of any action or proceeding
with respect to which indemnification may be sought hereunder, such Indemnified
Person shall notify the Indemnitor of such claim or demand or the commencement
of such action or proceeding, but failure so to notify the Indemnitor shall not
relieve the Indemnitor from any liability which the Indemnitor may have
hereunder or otherwise, unless the Indemnitor shall be materially prejudiced by
such failure.  If the Indemnitor shall so elect, the Indemnitor shall assume the
defense of such claim, demand, action or proceeding, including the employment of
counsel reasonably satisfactory to such Indemnified Person, and shall pay the
fees and disbursements of such counsel.  In the event, however, that such
Indemnified Person shall reasonably determine in its judgment that having common
counsel would present such counsel with a conflict of interest or alternative
defenses shall be available to an Indemnified Person or if the Indemnitor shall
fail to assume the defense of the claim, demand, action or proceeding in a
timely manner, then such Indemnified Person may employ separate counsel to
represent or defend such Person against any such claim, demand, action or
proceeding and the Indemnitor shall pay the reasonable fees and disbursements of
such counsel; provided, however, that the Indemnitor shall not be required to
              --------  -------                                              
pay the fees and disbursements of more than one separate counsel for all
Indemnified Persons in any jurisdiction in any single action or proceeding.  For
any claim, demand, action or proceeding the defense of which the Indemnitor
shall assume, the Indemnified Person shall have the right to participate therein
and to retain its own counsel at such Indemnified Person's own expense (except
as otherwise provided in this Section 15.4), so long as such participation does
not interfere with the Indemnitor's control of such claim, demand, action or
proceeding.  The Indemnitor shall not, without the prior written consent of the
Indemnified Person, settle or compromise or consent to the entry of any judgment
in any pending or threatened claim, action, suit or proceeding in respect of
which indemnification may be sought hereunder unless such settlement, compromise
or consent shall include an unconditional release of such Indemnified

 
                                                                              30

Person from all liability arising out of such claim, demand, action or
proceeding and would not prohibit, restrict or impair the Indemnified Person or
the Joint Venture from engaging in any business.

successors and permitted assigns, but neither this Agreement nor any of the

Purchaser may assign its rights under this Agreement, in whole or in part, to
