ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Our Fourth Amended and Restated Articles of Incorporation eliminate, as
permitted by Section 14-2-202(b)(4) of the Georgia Business Corporation Code,
the personal liability of directors and officers for monetary damages to the
corporation or its shareholders for breach of their duty of care and other
duties; provided, however, that our Articles of Incorporation and Section
14-2-202(b)(4) of the Georgia Code do not permit us to eliminate or limit
liability for (1) a breach of duty involving appropriation of a business
opportunity of ours; (2) an act or omission which involves intentional
misconduct or a knowing violation of law; (3) any transaction from which an
improper personal benefit is derived; or (4) any payments of a dividend or any
other type of distribution that is illegal under Section 14-2-832 of the Georgia
Code. In addition, if at any time the Georgia Code is amended to authorize
further elimination or limitation of personal liability, then the liability of
each of our directors and officers shall be eliminated or limited to the fullest
extent permitted by such provisions, as so amended, without further action by
the shareholders, unless the provisions of the Georgia Code require such action.

     Sections 14-2-850 to 14-2-859, inclusive, of the Georgia Code govern the
indemnification of directors, officers, employees and agents. Section 14-2-851
of the Georgia Code provides for indemnification of any of our directors for
liability incurred by him in connection with any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative,
arbitrative or investigative and whether formal or informal, in which he may
become involved by reason of being a member of our board of directors. Section
14-2-851 also provides such indemnity for directors who, at our request, act as
directors, officers, partners, trustees, employees or agents of another foreign
or domestic corporation, partnership, joint venture, trust, employee benefit
plan or another enterprise. Section 14-2-851 permits indemnification if the
director acted in a manner he believed in good faith to be in or not opposed to
our best interest and, in addition, in criminal proceedings, if he had no
reasonable cause to believe his conduct was unlawful. If the required standard
of conduct is met, indemnification may include judgments, settlements,
penalties, fines or reasonable expenses, including attorneys' fees, incurred
with respect to a proceeding. However, if the director is adjudged liable to us
in a derivative action or on the basis that personal benefit was

                                      II-2
<PAGE>   4

improperly received by him, the director will only be entitled to such
indemnification for reasonable expenses as a court finds to be proper in
accordance with the provisions of Section 14-2-854.

     Section 14-2-852 of the Georgia Code provides that directors who are
successful with respect to any claim brought against them, which claim is
brought because they are or were directors, are entitled to indemnification
against reasonable expenses as of right. Conversely, if the charges made in any
action are sustained, the determination of whether the required standard of
conduct has been met will be made, in accordance with the provisions of Section
14-2-855 of the Georgia Code, as follows: (1) if there are two or more
disinterested members of the board of directors, by the majority vote of a
quorum of the disinterested members of the board of directors, (2) by a majority
of the members of a committee of two or more disinterested directors, (3) by
special legal counsel or (4) by the shareholders, but, in such event, the shares
owned by or voted under the control of directors seeking indemnification may not
be voted.

     Section 14-2-857 of the Georgia Code provides that an officer who is not a
director has the mandatory right of indemnification granted to directors under
Section 14-2-852, as described above. In addition, we may, as provided by our
Articles, Bylaws, general or specific actions by our board of directors, or by
contract, indemnify and advance expenses to an officer, employee or agent who is
not a director to the extent that such indemnification is consistent with public
policy.

     We plan to enter into indemnification agreements with each of our directors
and certain executive officers. The indemnification agreements set forth certain
procedural matters relating to indemnification, including the manner in which an
indemnified party may make a claim and the right of an indemnified party to
court adjudication of his or her claim if we deny such indemnification.

     Our officers and directors are presently covered by insurance which (with
certain exceptions and within certain limitations) indemnifies them against any
losses or liabilities arising from any alleged "wrongful act," including any
alleged breach of duty, neglect, error, misstatement, misleading statement,
omissions or other act done or wrongfully attempted. We pay the cost of such
insurance as permitted by our Bylaws and the laws of the State of Georgia.

     Reference is hereby made to Section        of the underwriting agreement,
the form of which will be filed as Exhibit 1.01 hereto, in which the
underwriters agree to indemnify our directors and officers and certain other
persons against certain civil liabilities.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES

     In the three years preceding the filing of this registration statement, we
have sold and issued the following securities:

          1. In April, May and August 1999, we issued an aggregate of 5,899,999
             shares of Series C convertible preferred stock to 21 investors for
             a consideration of $3.00 per share, or an aggregate of $17,699,997
             before expenses of the private placements of approximately
             $164,000. In accordance with the terms of the Series C convertible
             preferred stock, each share of Series C convertible preferred stock
             will be converted into one share of our common stock immediately
             prior to the consummation of the public offering.

          2. In August and December 1998, we issued $6,150,000 principal amount
             notes bearing interest at a rate per annum equal to the prime rate
             as published in The Wall Street Journal plus 2%. At that time we
             also issued warrants exercisable for 200,001 shares of our Series B
             convertible preferred stock. In April 1999 we issued warrants
             exercisable for 205,002 shares of our Series C convertible stock to
             the noteholders as consideration for extending the maturity of the
             notes. The notes and, at the option of the noteholders, the accrued
             and unpaid interest on the notes were converted into 2,140,357
             shares of our Series C convertible preferred stock in April 1999.
             In accordance with the terms of the Series B convertible preferred
             stock and the Series C convertible preferred stock, each share of
             convertible preferred stock will be converted into one share of our
             common stock immediately prior to the consummation of the public
             offering.
                                      II-3
<PAGE>   5

          3. From January 1, 1997 through February 18, 2000, we granted
             incentive stock options and nonqualified stock options to purchase
             an aggregate of 3,097,000 shares of our common stock at exercise
             prices ranging from $.30 to $.38 per share to employees and
             directors under our 1995 Stock Option Plan and our 1997 Equity
             Ownership Plan, and issued an aggregate of 254,597 shares upon the
             exercise of these and previously granted options. Of these options
             granted, options to purchase 408,328 shares of common stock have
             been canceled.

          4. In July 1998, we issued to Cousins Properties, Inc. a warrant to
             purchase 50,000 shares of our Series B-1 convertible preferred
             stock at an exercise price of $5.00 per share. This warrant will be
             converted into a warrant to purchase 50,000 shares of our common
             stock at an exercise price of $5.00 per share immediately prior to
             the consummation of the public offering in accordance with the
             terms of the Series B-1 convertible preferred stock.

          5. In December 1998, we issued to Long Aldridge & Norman LLP 16,666
             shares of Series B convertible stock for consideration of $3.00 per
             share or an aggregate of $49,998 in legal fees incurred by
             AtheroGenics in 1998. In accordance with the terms of the Series B
             convertible preferred stock, each share of Series B convertible
             preferred stock will be converted into one share of our common
             stock prior to the consummation of the public offering.

          6. In April 1999, we issued to Long Aldridge & Norman LLP 16,666
             shares of Series C convertible stock for consideration of $3.00 per
             share or an aggregate of $49,998 in legal fees incurred by
             AtheroGenics in 1998. In accordance with the terms of the Series C
             convertible preferred stock, each share of Series C convertible
             preferred stock will be converted into one share of our common
             stock prior to the consummation of the public offering.

          7. In October 1997, we issued to Phoenix Leasing Incorporated a
             warrant to purchase 2,200 shares of Series B convertible preferred
             stock at an exercise price of $3.00 per share in connection with
             the Master Lease Agreement between Phoenix Leasing and us dated
             November 1, 1995. This warrant will be converted into a warrant to
             purchase 2,200 shares of our common stock at an exercise price of
             $3.00 per share immediately prior to the consummation of the public
             offering in accordance with the terms of the Series B convertible
             preferred stock.

     No underwriters were involved in the foregoing sales of securities. The
issuance of the above securities were deemed to be exempt from registration
under the Securities Act in reliance on Section 4(2) of such Securities Act as
transactions by an issuer not involving any public offering, or, in the case of
some options to purchase common stock, Rule 701 of the Securities Act. The
recipients of securities in each such transaction represented their intentions
to acquire the securities for investment only and not with a view to or for sale
in connection with any distribution thereof and appropriate legends were affixed
to the share certificates and warrants issued in such transactions. All
recipients had adequate access, through their relationships with us, to
information about us.

ITEM 17.  UNDERTAKINGS

     The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

     The undersigned registrant hereby undertakes that:

          (1) For purposes of determining any liability under the Securities
     Act, the information which may be omitted from the form of prospectus filed
     as part of this registration statement in reliance upon Rule 430A and
     contained in a form or prospectus filed by the registrant pursuant to Rule
     424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be
     part of this registration statement as of the time it was declared
     effective.

          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

         2.1      Exclusive License Grant.

                  (a) License. Subject to the terms and conditions of this
         Agreement, Licensor hereby grants to SPL, as of the Effective Date, an
         exclusive license (exclusive even as to Licensor) under the Patent
         Rights and Licensor Know-How in the Territory to develop, make, have
         made, import, export, use, distribute, market, promote, offer for sale
         and sell: (i) Licensed Compound(s) and/or Licensed Product(s)
         containing Licensed Compound; and (ii) compound(s) in the Compound
         Library other than Licensed Compound, and/or Licensed Product(s)
         containing such compound(s) for the Primary Indication and the

                  (b) Co-Exclusive License to Other Indications Subject to the
         terms and conditions of this Agreement, Licensor hereby grants to SPL,
         as of the Effective Date, a co-exclusive license under the Patent
         Rights and Licensor Know-How in the Territory to develop, make, have
         made, import, export, use, distribute, market, promote, offer for sale
         and sell compound(s) in the Compound Library other than Licensed
         Compound, and/or Licensed Product(s) containing such compound(s), for
         any and all indications other than



                                       6
<PAGE>   13

         the Primary Indication and Secondary Indication. The term "co-exclusive
         license" shall mean that with respect to the rights granted to SPL
         under this Section 2.1(b), Licensor retains the same rights as are
         granted to SPL. With respect to a given compound, indication or
         territory, each of Licensor and SPL may either directly exercise and
         exploit its co-exclusive rights or grant a co-exclusive license under
         such rights, either in whole or in part, to one (1) third party or
         Affiliate.

                  (c)      Right to Sublicense. The licenses granted to SPL
         under Sections 2.1(a) and 2.1(b) shall include the right to grant
         sublicenses to Affiliates and/or any third party (to the extent
         provided therein), provided that SPL remains responsible to Licensor
         under this Agreement for the performance of its Sublicensees.

                  (d)      Retained Rights Subject to the restrictions set forth
         in Section 2.11, Licensor retains all rights under the Patent Rights
         not expressly granted to SPL by this Section 2.1, and the right to use
         Licensor Know-How pursuant to Sections 2.6(h) and 5.1(c) below.

                  (e)      Third Party Agreements. As of the Execution Date,
         Licensor is a party to certain agreements (as listed in Schedule
         2.1(e), redacted copies of which have been provided to SPL) with third
         parties pursuant to which Licensor has acquired rights to certain
         patent applications, patents and technology, which agreements are
         relevant to the Patent Rights and/or Licensor Know-How. The parties
         acknowledge that the licenses granted to SPL under this Agreement are,
         or may be, subject to the specific rights retained by or granted to the
         U.S. Government, and/or the rights for research use retained by such
         third parties, under those agreements. In the event that on or after
         the Execution Date and during the Term of this Agreement, Licensor
         acquires any additional Patent Rights or Licensor Know-How from any
         third parties, by assignment, license or otherwise, Licensor shall
         promptly notify SPL in writing to that effect, and provide SPL with a
         copy (which may be redacted) of the agreement(s) with such third party.
         To the extent that the copies of the agreements listed in Schedule
         2.1(e) which were provided to SPL, or any other agreements provided to
         SPL under this Section 2.1(e), have been redacted, Licensor represents
         and warrants that the redacted portions of such agreements have no
         material effect on the scope of the licenses or other rights granted to
         SPL under this Agreement. Nothing herein shall be construed as granting
         to SPL any greater rights under the Patent Rights and/or Licensor
         Know-How than those held by Licensor

         2.2      Non-Exclusive License Grant. In the event that the
development, making, having made, importing, exporting, use, distribution,
marketing, promotion, offering for sale or sale by SPL, its Affiliates and/or
Sublicensees of Licensed Product in the Territory would infringe during the Term
of this Agreement a claim of an issued letters patent, and/or any patent rights
which Licensor owns or has the rights to license and which patents are not
covered by the grant in Section 2.1, Licensor hereby grants to SPL and its
Affiliates, to the extent Licensor is legally able to do so, a non-exclusive,
royalty-free license in the Territory under such issued letters patent



                                       7

solely for SPL, its Affiliates and/or Sublicensees to discover, develop, make,
have made, use, distribute, market, promote, offer for sale and sell Licensed
Compound and/or Licensed Product(s) in the Territory.

         2.3      Disclosure of Information. Promptly after the Effective Date,
Licensor shall, at its own cost, disclose to SPL in writing, or via mutually
acceptable electronic media, copies or reproductions of all existing Licensor
Know-How not previously disclosed to SPL in order to enable SPL to exploit its
rights granted under Section 2.1 and, if applicable, Section 2.2 of this
Agreement. In addition, during the Term of this Agreement, Licensor shall
promptly disclose to SPL in writing, or via mutually acceptable electronic
media, on an ongoing basis copies or reproductions of all new Licensor Know-How
that is reasonably necessary for research, development, registration,
manufacture, marketing, use or sale of Licensed Compound and/or Licensed
Product. Such Licensor Know-How and other information shall be automatically
deemed to be within the scope of the licenses granted herein without payment of
any additional compensation. Upon SPL's request but reasonably subject to
Licensor's other business requirements, Licensor shall provide reasonable
technical assistance to enable SPL to utilize such additional Licensor Know-How,
provided, that SPL shall promptly reimburse Licensor for reasonable
out-of-pocket costs and expenses incurred by Licensor in providing such
technical assistance. Licensor shall invoice SPL for such costs and expenses,
and shall provide documentation for the invoice. The invoice shall be payable to
Licensor or its designee(s) [ * ] after receipt by SPL of the invoice provided,
however, that such cost and out-of-pocket expenses must be identified prior to
being committed to by Licensor and provided to SPL to determine whether SPL
agrees to have the technical assistance provided at such cost and the final
amount sought to be reimbursed shall not exceed [ * ] of the estimated cost
without SPL's prior written consent. SPL shall be under no obligation to
reimburse Licensor for out-of-pocket costs and expenses incurred by Licensor
without SPL's agreement. SPL shall have the right to use for all purposes in
connection with obtaining any Regulatory Approval for the Licensed Product(s)
all Licensor Know-How and other information, disclosed pursuant to this Section
and under this Agreement.

         2.4      HSR Filing and Approvals.

                  (a)      HSR Filing. To the extent necessary, each of Licensor
         and SPL shall file, within ten (10) days after the date of this
         Agreement, with the Federal Trade Commission (the "FTC") and the
         Antitrust Division of the United States Department of Justice (the
         "Antitrust Division") any notification and report form (the "Report")
         required of it in the reasonable opinion of either or both Parties
         under the HSR Act with respect to the transactions as contemplated
         hereby and shall cooperate with the other Party to the extent necessary
         to assist the other Party in the preparation of its Report and to
         proceed to obtain necessary approvals under the HSR Act, including but
         not limited to the expiration or earlier termination of any and all
         applicable waiting periods required by the HSR Act.

                  (b)      Licensor's Obligations. Licensor shall use good faith
         reasonable efforts to



                                       8
<PAGE>   15

         assist SPL in eliminating any concern on the part of any court or
         government authority regarding the legality of the proposed
         transaction, including, if required by federal or state antitrust
         authorities, SPL's promptly taking all reasonable steps to secure
         government antitrust clearance. Licensor shall cooperate in good faith
         at its own cost with any government investigation and promptly produce
         documents and information demanded by a second request for documents
         and of witnesses if requested.

                  (c)      Additional Approvals. Each of Licensor and SPL will
         cooperate and use all reasonable efforts to make all other
         registrations, filings and applications, to give all notices and to
         obtain as soon as practicable all governmental or other consents,
         transfers, approvals, orders, qualifications authorizations, permits
         and waivers, if any, and to do all other things reasonably necessary or
         desirable in SPL's opinion for the consummation of the transactions as
         contemplated hereby (including, without limitation, those acts required
         to obtain necessary approvals under any foreign equivalent antitrust
         statute to the HSR Act or regulation from any government or regulatory
         authority having the requisite jurisdiction; provided, however, that
         SPL shall promptly reimburse Licensor for reasonable out-of-pocket
         costs and expenses incurred by Licensor in providing such cooperation.
         Licensor shall invoice SPL for such costs and expenses, and shall
         provide supporting documentation for the invoice. The invoice shall be
         payable to Licensor or its designee(s) [ * ] days after receipt by SPL
         of the invoice.

         2.5      Joint Management Committee. The Parties shall establish a
Joint Management Committee (the "JMC") to oversee the development and
commercialization program for Licensed Product for the Primary Indication and
the Secondary Indication, and to facilitate the exchange of information between
the Parties. The JMC will generally serve in an advisory capacity with respect
to the development and commercialization activities to be performed by SPL under
this Agreement, with SPL retaining final decision making authority with respect
to all such matters.

                  (a)      Composition of the JMC. The JMC shall be composed of
         up to three (3) representatives from each of SPL and Licensor, and a
         quorum shall consist of at least one (1) JMC representative from each
         Party. In any matter before the JMC, each Party shall have one (1)
         vote, with decisions being made by unanimous decision. SPL shall
         seriously consider the recommendations and decisions of the JMC. A
         Party's representatives to the JMC shall serve at the discretion of
         such Party and may be substituted for or replaced at any time by such
         Party. The JMC shall be chaired by a representative of SPL. The
         Chairperson shall be responsible for calling meetings, preparing
         agendas and preparing and issuing minutes of each meeting within
         [ * ] thereafter.

                  (b)      JMC Meetings. The JMC shall meet at least once each
         Calendar Quarter during the Term of this Agreement, until such time as
         the Parties agree to a more or less frequent meeting schedule. The site
         of such meetings shall alternate between the offices of SPL and
         Licensor (or any other site mutually agreed upon by the Parties) and
         each



                                       9
<PAGE>   16

         Party shall bear its own costs of attending such meetings. All meetings
         of the JMC shall be summarized in writing and sent to both Parties and
         countersigned by both Parties.

                  (c)      JMC Responsibilities. The JMC will be generally
         responsible for monitoring the status of SPL's development and
         commercialization activities with respect to Licensed Product and for
         preparing recommendations for implementation by SPL with regard to: (i)
         selection of Licensed Compounds for development by SPL as Licensed
         Products for the Primary Indication; (ii) preclinical and clinical
         development plans; (iii) development timelines and scheduling; (iv)
         strategies for obtaining and maintaining Regulatory Approvals; (v)
         marketing and sales strategies for Licensed Product.

                  (d)      Deadlock. In the event that the JMC is unable to
         reach a decision by unanimous vote with respect to any matter, then SPL
         shall have final decision making authority with respect thereto.


         2.6      SPL's Development Obligations.

                  (a)      SPL Diligence. SPL shall, at SPL's expense, and
         subject to Licensor's compliance with its obligations under Sections
         2.3 and 2.4, use good faith reasonable efforts to develop, obtain
         Regulatory Approval for, and commercialize the Licensed Product(s) in
         the Territory for the Primary Indication. SPL shall have the option, in
         its sole discretion, to seek Regulatory Approval for the Licensed
         Product for any additional indications it determines are desirable, but
         shall have no diligence obligations to Licensor with respect thereto
         with the exception of those expressly set forth in Section 2.11(d). The
         Parties acknowledge and agree that all business decisions including,
         without limitation, decisions relating to SPL's research, development,
         registration, manufacture, sale, commercialization, design, price,
         distribution, marketing and promotion of Licensed Products covered
         under this Agreement, shall be within the sole discretion of SPL.
         Licensor acknowledges that SPL is in the business of developing,
         manufacturing and selling pharmaceutical products and, subject to the
         provisions of this Section, nothing in this Agreement shall be
         construed as restricting such business or imposing on SPL the duty to
         market and/or sell and exploit Licensed Compound or Licensed Product
         for which royalties are payable hereunder to the exclusion of, or in
         preference to, any other product, or in any way other than in
         accordance with its normal commercial practices.

                  (b)      Opportunity to Cure. If, in Licensor's reasonable
         opinion, SPL fails to comply with any of its diligence obligations
         under Sections 2.6(a) and (c), then Licensor shall have the right to
         give SPL written notice thereof stating in reasonable detail the
         particular failure(s). SPL shall have a period [ * ] days from the
         receipt of such notice to correct the failure or, in the event that the
         failure cannot be reasonably cured within a [ * ] day period, then SPL
         shall initiate actions reasonably expected to cure the failure within
         [ * ] days of receiving notice and shall thereafter diligently pursue
         such actions to cure



                                       10
<PAGE>   17

         the failure (even if requiring longer than the [ * ] days specified in
         Section 8.4(a)(i)). In the event of a dispute as to whether or not SPL
         has failed to exercise due diligence under Sections 2.6(a) and 2.6(c),
         or whether SPL is diligently pursuing actions reasonably expected to
         cure such failure under this Section 2.6(b), such dispute shall be
         resolved through binding arbitration in accordance with Section 9.2.

                  (c)      Research and Development Activities. As of the
         Effective Date, SPL shall be responsible, at its cost and expense, and
         in its sole judgment, for all research and development activities which
         are necessary to obtain Regulatory Approval for a Licensed Product in
         the Territory for the Primary Indication and any post-approval studies
         required as a condition of obtaining any Regulatory Approval for a
         Licensed Product for the Primary Indication. The parties acknowledge
         and agree that SPL's obligations under this Section 2.6(c) shall
         include all of the costs of conducting the CART Study (whether incurred
         before or after the Effective Date) which are estimated at [ * ]. In
         addition, SPL shall be responsible for any other studies (or portions
         of studies) necessary or desirable, in its sole judgment, for
         maintaining any Regulatory Approval (for the Primary Indication or any
         other indication for which SPL, in its sole discretion, may decide to
         seek Regulatory Approval) in the Territory, as well as any
         pre-marketing studies prior to such Regulatory Approval and
         post-marketing studies conducted following a Regulatory Approval.

                  (d)      Licensed Product Registrations; Pricing Reimbursement
         Approvals. Subject to its diligence obligations set forth in Section
         2.6(a), SPL shall be responsible, at its cost and expense, and in its
         sole judgment, for determining the appropriate regulatory strategy, for
         obtaining and maintaining all Regulatory Approvals and for obtaining
         and maintaining any pricing and reimbursement approvals required for
         the sale of Licensed Product in the Territory. Each Regulatory Approval
         and each pricing and reimbursement approval shall be placed in SPL's
         name or the name of a SPL Affiliate unless applicable law requires, or
         Licensor and SPL otherwise agree, that an approval be solely or jointly
         in the name of Licensor or a designated Licensor Affiliate. Licensor
         agrees that notwithstanding such Regulatory Approval or pricing and
         reimbursement approval in its name, SPL retains the exclusive rights to
         make, have made, import, export, use, distribute, promote, offer for
         sale and sell Licensed Compound and/or Licensed Product(s) as granted
         SPL in Section 2.1.

                  (e)      Data. SPL shall own all data arising out of studies
         performed by or on behalf of SPL under this Article II.

                  (f)      Assistance by Licensor. In connection with any NDA,
         HRD or other application for Regulatory Approval relating to Licensed
         Product, Licensor shall, at SPL's request, provide to SPL in a prompt
         manner responses to questions which have been raised by any regulatory
         authority in connection with such application for Regulatory Approval
         and further provide to SPL estimates of Licensor's [ * ] costs for


                                       11
<PAGE>   18

         rendering such assistance. Licensor shall assist SPL from time to time,
         at SPL's request, in the design and implementation of clinical studies.
         Subject to Licensor's rights under Section 3.3(b), Licensor shall
         assist SPL to enable SPL to self-source bulk material for the
         manufacture of Licensed Compound and/or Licensed Product; provided,
         however, that SPL shall have no obligation whatsoever to purchase any
         bulk material or Licensed Compound from Licensor.

                  (g)      Reimbursement of Costs by SPL

                           (i) SPL shall reimburse Licensor for its reasonable
         [ * ] costs and expenses incurred in rendering assistance under Section
         2.6(f) (but no more than [ * ] of those costs which Licensor estimated,
         as provided above, that the work would cost unless SPL provides written
         approval). Licensor shall invoice SPL for such costs and expenses, and
         shall provide documentation for the invoice. The invoice shall be
         payable to Licensor or its designee(s) [ * ] days after receipt by SPL
         of the invoice, provided, however, that SPL shall be under no
         obligation to reimburse Licensor for [ * ] costs and expenses incurred
         by Licensor without SPL's agreement.

                           (ii) SPL shall reimburse Licensor for its reasonable
         [ * ] costs and expenses incurred in performing research and
         development activities under Section 2.6 (h) (but no more than [ * ] of
         those costs which Licensor estimated, as provided below, that the work
         would cost unless the JMC provides written approval). Licensor shall
         invoice SPL for such costs and expenses, and shall provide
         documentation for the invoice. The invoice shall be payable to Licensor
         or its designee(s) [ * ] days after receipt by SPL of the invoice,
         provided, however, that SPL shall be under no obligation to reimburse
         Licensor for research and development costs and expenses incurred by
         Licensor without the prior approval of the JMC.

                  (h)      Licensor's Additional Development Obligations. In
         addition to Licensor's obligations under Section 2.6(f), the JMC will
         assign to Licensor the responsibility to conduct, on SPL's behalf and
         at SPL's expense, certain of the research and development activities,
         including clinical studies involving Licensed Product, for which SPL is
         responsible under Section 2.6(c). The nature and extent of the research
         and development activities to be conducted by Licensor is generally set
         forth in Schedule 2.6(h). The JMC shall determine the specific aspects
         of such activities, including the timing and costs of the work to be
         performed by Licensor. Licensor agrees to use good faith reasonable
         efforts to complete such activities in the manner determined by the
         JMC, and shall have the right to utilize contract research
         organizations and other third party contractors in the performance of
         such activities, provided that Licensor shall remain responsible for
         the performance of all such contractors. To the extent that Licensor
         utilizes third party contractors to perform such activities, Licensor
         shall enter into suitable agreements with


                                       12
<PAGE>   19

         such contractors, which agreements shall incorporate provisions
         consistent with the terms and conditions of this Agreement, including,
         without limitation, provisions governing confidentiality, ownership of
         data, inventions and other intellectual property arising from such
         activities, financial obligations and termination rights. Licensor
         shall keep the JMC informed with regard to such third party contracts
         and shall provide SPL with a copy of all such agreements. Any research
         and development activities conducted by Licensor or its contractors
         pursuant to this Section 2.6(h) shall be performed in accordance with
         good laboratory practices and good clinical practices, and in
         compliance with all applicable laws, rules and regulations in the U.S.
         and the EU, and shall meet current regulatory standards. SPL shall
         promptly notify Licensor in the event that SPL reasonably determines
         that all or any part of the work performed by Licensor and/or its
         contractors under this Section 2.6(h) fails to meet such standards. If
         Licensor reasonably disagrees with such determination, the parties
         shall refer the matter to an independent expert (selected by mutual
         agreement of the parties) to determine whether or not the study must be
         repeated to support Regulatory Approval for Licensed Product. In the
         event that Licensor and/or the independent expert agrees with SPL's
         determination and such studies are repeated, then SPL shall have the
         right to deduct the [ * ] costs of repeating such work from [ * ]
         payments due Licensor under this Agreement.

                  (i)      Adverse Event Reporting Licensor shall promptly
         report to SPL any information regarding adverse events related to the
         use of the Licensed Product in accordance with the Adverse Event
         Reporting Procedures (as may be amended from time to time upon mutual
         agreement) set forth in Schedule 2.6(i) and incorporated herein by
         reference. To the extent that Licensor holds any INDs or otherwise has
         any adverse event reporting obligations with respect to Licensed
         Product, SPL shall promptly report to Licensor any information
         regarding adverse events related to the use of Licensed Product in
         accordance with such Adverse Event Reporting Procedures.

         2.7      Independent Discoveries by SPL. Licensor acknowledges that SPL
and/or its Affiliates have ongoing research programs which may now or in the
future independently discover, develop and/or acquire technologies and/or
products relating to treatment and prevention of any disease, disorder or
condition in humans or animals. Licensor agrees that such technologies and
products, to the extent discovered without use of Licensor Know-How, will not be
deemed to be Licensor Know-How and are outside the scope of this Agreement.

         2.8      Excused Performance. In addition to the provisions of Article
VIII and Section 9.9, the obligations of SPL with respect to a Licensed Product
under Sections 2.6(a), 2.6(c), 2.6(d) and 2.11(d) are expressly conditioned upon
the continuing absence of any adverse condition or event which warrants a delay
in commercialization of a Licensed Product including, but not limited to, an
adverse condition or event relating to the safety or efficacy of a Licensed
Product or unfavorable labeling, pricing or pricing reimbursement approvals, or
lack of Regulatory Approval, and the obligation of SPL to develop or market any
such Licensed Product shall be delayed or suspended so long as in SPL's
reasonable opinion any such condition or event exists.

         2.9      Supply of Licensed Compound/Licensed Product. Licensor shall
be responsible, at Licensor's expense, for supplying SPL with Licensed Compound
(in the form of bulk active), from Licensor's existing inventory of Licensed
Compound, to enable SPL to perform [ * ]. In addition, Licensor has the limited
option to supply all of SPL's requirements of Licensed Products as set forth in
Section 3.3(b). All Licensed Compound to be supplied by Licensor hereunder shall
be delivered FCA (Kenilworth, New Jersey) (Incoterms 1990) via a carrier to be
specified by SPL. Licensor warrants and represents that all supplies of Licensed
Compound provided to SPL by Licensor shall conform to the applicable
specifications for such Licensed Compound and were prepared in accordance with
current Good Manufacturing Practices ("cGMPs") and other applicable federal,
national, state and local laws and regulations in effect at the time of
manufacture. SPL shall be responsible for the formulation and packaging of the
Licensed Compound provided by Licensor hereunder, and for manufacture and supply
of all Licensed Compound and/or Licensed Product necessary for the performance
of [ * ] and for supplying all commercial quantities of Licensed Compound and
Licensed Products. Licensor shall transfer to SPL all Licensor Know-How relating

completion, and results of the major phases of clinical development of Licensed
Product, including but not limited to Phase II and Phase III clinical trials,
NDA and HRD submissions, NDA and HRD filings, approvable and approval letters,
and launch.

         2.11     Non-Compete Provision. Subject to the terms of Section 9.1(b),
Licensor and its Affiliates shall be subject to the non-compete obligations set
forth in this Section 2.11.

                  (a)      During the Term of this Agreement, Licensor shall not
         undertake a development program for, or commercialize, either on its
         own or in collaboration with any third party:

         [  *  ]

                  (b)      For the period extending from the Effective Date
         until the earlier of [ * ] after the First Commercial Sale of Licensed
         Product in the Territory or [ * ], Licensor shall not, either on its
         own or in collaboration with any third party:

         [  *  ]

                  (c)      The foregoing notwithstanding, Licensor shall at all
         times retain the right to develop and commercialize topical products
         containing any compound other than the

         to the performance by Licensor of pre-clinical research activities with
         respect to compounds owned or controlled by such third parties,
         provided that such compounds do not compete through the same mechanism
         of action with the Licensed Compound (as determined using the same
         criteria as set forth in Section 6.2(k)) with respect to the Primary
         Indication and/or the Secondary Indication.

                  (d)      Licensor's non-compete obligations under Section
         2.11(b)(ii) are expressly conditioned upon SPL's initiating a
         development program for Licensed Product for the Secondary indication
         within [ * ] years after the Effective Date, and thereafter using good
         faith reasonable efforts to develop and commercialize one or more
         Licensed Products for the Secondary Indication.

                      (iii) [ * ]

                      (iv)  [ * ]

                      (v)   [ * ]

                  (b)      Sales Milestones:

                      (i)   [ * ]

                      (ii)  [ * ]

                      (iii) [ * ]

                      (iv)  [ * ]

         The foregoing sales milestone payments are in addition to any royalty
         payments due Licensor under Section 3.3 with respect to sales of
         Licensed Product. For purposes of clarity, the parties acknowledge that
         (1) the first achievement of more than one of the above sales
         milestones in the same Calendar Year shall not affect SPL's obligation
         to make the relevant sales milestone payments to Licensor, and (2)
         annual worldwide sales of the Licensed Product shall be determined
         based upon the aggregate total of sales in the Territory under this
         Agreement and sales in countries outside the Territory under the
         International Agreement.

                  (c)      Limitations. Except as expressly set forth below,
         each development milestone payment under Section 3.2(a) and each sales
         milestone payment under Section 3.2(b) shall be payable one (1) time
         only on the first occurrence of the indicated event regardless of the
         number of times the event triggering the payment of such milestone
         occurs. If the triggering event for a given milestone payment does not
         occur prior to the effective date of termination, or the expiration, of
         this Agreement, SPL shall have no obligation to pay such milestone
         payment to Licensor. The Parties acknowledge and agree that nothing
         herein shall be construed as representing an estimate or projection of
         anticipated sales or the actual value of Licensed Compounds or Licensed
         Products, and the figures set forth in Section 3.2(b) are merely
         intended to define SPL's obligations to Licensor in the event such
         sales performance is achieved.

         3.3      Royalties. In further consideration for the licenses granted
to SPL hereunder, for so long as the Licensed Product is covered by a Valid
Claim in the Territory at the time of sale by SPL, and subject to the provisions
of Section 3.3 (a)-(c), SPL shall pay to Licensor royalties on a
country-by-country basis of [ * ] of SPL's, its Affiliates' or its Sublicensees'
Net Sales of Licensed Product in the Territory. With respect to countries in the
Territory where no such Valid Claim exists, the royalty rate shall be [ * ], and
such royalties shall be paid for [ * ] years from



                                       16
<PAGE>   23

the first commercial sale of Licensed Product in such country. No royalties
shall be due upon the sale or other transfer among SPL, its Affiliates or
Sublicensees, but in such cases the royalty shall be due and calculated upon
SPL's or its Affiliates' or its Sublicensees' Net Sales to the first independent
third party. No royalties shall accrue on the disposition of Licensed Product by
SPL, its Affiliates or Sublicensees as samples (promotion or otherwise) or as
donations (for example, to non-profit institutions or government agencies for a
non-commercial purpose) or for clinical studies. Such dispositions by SPL shall
not be included in the determination of Net Sales during the period of time in
which such third party sales are occurring.

                  (a)      Cap on Royalties Plus Cost of Goods. The parties
         acknowledge and agree that the total of (i) royalties payable by SPL to
         Licensor under this Agreement, and (ii) the Cost of Goods of Licensed
         Product manufactured by SPL and/or paid by SPL to third parties for the
         manufacture of Licensed Product, shall not exceed [ * ] of Net Sales of
         Licensed Product. SPL shall use good faith reasonable efforts to keep
         the Cost of Goods of Licensed Product from exceeding [ * ] of Net
         Sales. SPL shall determine the Cost of Goods for the Licensed Product
         in a timely manner, and in no event later than the date of filing of
         the first NDA for the Licensed Product in the United States. In the
         event that notwithstanding such efforts by SPL the Cost of Goods for
         Licensed Product does exceed [ * ] of Net Sales, then SPL shall notify
         Licensor in writing to that effect. Following receipt of such notice,
         Licensor shall have the right to have an independent auditor review
         SPL's relevant records and make an independent determination of the
         Cost of Goods for the Licensed Product. Any such audit shall be
         conducted under terms and conditions essentially the same as those set
         forth in Section 3.7.

                  (b)      Licensor's Option to Manufacture. In the event that
         SPL's Cost of Goods for the Licensed Product is correctly determined to
         exceed [ * ] of Net Sales, Licensor shall have the right to manufacture
         and supply, or to seek a third party supplier able to manufacture and
         supply, SPL's requirements of Licensed Product at a Cost of Goods equal
         to or less than [ * ] of Net Sales for Licensed Product. If Licensor is
         able, or locates a third supplier able, to manufacture and supply
         Licensed Product at a Cost of Goods equal to or less than [ * ] of Net
         Sales, SPL shall in good faith negotiate and enter into a suitable
         supply agreement with Licensor or such third party, as appropriate, for
         the manufacture and supply of Licensed Product. Any such agreement
         shall include terms obligating SPL to purchase, and Licensor or the
         third party to manufacture and supply, all of SPL's requirements of
         Licensed Product at a Cost of Goods to be agreed upon, not to exceed [
         * ] of Net Sales of Licensed Product. All supplies of Licensed Product
         to be provided to SPL by Licensor or such third party manufacturer
         pursuant to this Section 3.3(b) shall be manufactured at a qualified
         manufacturing site, shall conform to the applicable specifications for
         Licensed Product and shall be prepared in accordance with cGMPs and all
         applicable federal, national, state and local laws and regulations in
         effect at the time of manufacture.

                  (c)      Royalty Reduction. In the event that SPL's Cost of
         Goods for Licensed Product are correctly determined to exceed [ * ] of
         Net Sales of Licensed Product and Licensor is unable to identify a
         third party capable of supplying SPL's requirements of Licensed Product
         at a price equal to or less than [ * ] of Net Sales of Licensed
         Product, then SPL shall remain responsible for the manufacture and
         supply of Licensed Product and the royalty rate to be paid by SPL under
         this Section 3.3 shall be reduced so that the total of (i) royalties
         payable by SPL to Licensor under this Agreement, and (ii) the Cost of
         Goods of Licensed Product manufactured by SPL and/or paid by SPL to
         third parties for the manufacture of Licensed Product, is equal to [ *
         ] of Net Sales of Licensed Product. Notwithstanding the foregoing, the
         royalty payable to Licensor under this Agreement shall not be reduced
         pursuant to this Section 3.3(c) to less then [ * ] where a Valid Claim
         exists, or [ * ] where no Valid Claim exists.

         3.4      Third Party Licenses. In the event that SPL's outside patent
counsel determines that patent licenses from third parties are required by SPL,
its Affiliates or its Sublicensees in order to discover, develop, make, have
made, import, export, use, distribute, promote, market, offer for sale or sell
Licensed Compound and/or Licensed Product (hereinafter "Third Party Licenses"),
SPL shall provide Licensor with written notice to that effect and shall be
solely responsible for acquiring such licenses at SPL's sole discretion. SPL may
reduce any royalty otherwise due Licensor hereunder to reimburse it for
royalties and or license fees actually paid to such third parties under any
Third Party Licenses of patent claims which would be infringed by the
manufacture, use, import, export or sale of Licensed Compound and/or Licensed
Product in the Territory. SPL shall have no right to reduce any royalty due
Licensor hereunder for any amounts paid to a third party under any Third Party
License to the extent it is a license to technology (other than Licensor
Know-How) or materials (other than Licensed Compound) selected by SPL for use in
connection with the Licensed Product. The amount of reduction of royalties due
Licensor and the amount of reimbursement to SPL shall be equal to [ * ] of the
royalties or license fees paid to such third parties in consideration for the
Third Party License but in no event shall the royalty due Licensor for any
Licensed Product in any country be thereby reduced to less than [ * ] of the
royalty rate otherwise due Licensor hereunder for such Licensed Product in such
country.

         3.5      Compulsory Licenses. If a compulsory license is granted under
the Patent Rights to a third party with respect to Licensed Compound and/or
Licensed Product in any country in the Territory with a royalty rate lower than
the royalty rate provided for under Section 3.3, then the royalty rate to be
paid by SPL on Net Sales in that country under Section 3.3 shall be reduced to
the rate paid by the compulsory licensee for so long as such compulsory license
is in effect.

         3.6      Reports; Payment of Royalty; Payment Exchange Rate and
Currency Conversions.

                  (a)      Royalties Paid Quarterly. Within [ * ] calendar days
         following the close of each Calendar Quarter, following the First
         Commercial Sale of a Licensed Product, SPL shall furnish to Licensor a
         written report for the Calendar Quarter showing the Net


                                       18
<PAGE>   25

         Sales of Licensed Product(s) sold by SPL, its Affiliates and its
         Sublicensees in the Territory during such Calendar Quarter and the
         royalties payable under this Agreement for such Calendar Quarter.
         Simultaneously with the submission of the written report, SPL shall pay
         to Licensor, for the account of SPL or the applicable Affiliate or
         Sublicensee, as the case may be, a sum equal to the aggregate royalty
         due for such Calendar Quarter calculated in accordance with this
         Agreement (reconciled for any previous overpayments or underpayments).

                  (b)      Method of Payment. Payments to be made by SPL to
         Licensor under this Agreement shall be paid by bank wire transfer in
         immediately available funds to such bank account as is designated in
         writing by Licensor from time to time. Royalties shall be deemed
         payable by the entity making the Net Sales from the country in which
         earned in local currency and subject to foreign exchange regulations
         then prevailing. Royalty payments shall be made in United States
         dollars to the extent that free conversions to United States dollars is
         permitted. The rate of exchange to be used in any such conversion from
         the currency in the country where such Net Sales are made shall be the
         rate of exchange used by Schering Corporation for reporting such sales
         for United States financial statement purposes. If, due to restrictions
         or prohibitions imposed by national or international authority,
         payments cannot be made as aforesaid, the Parties shall consult with a
         view to finding a prompt and acceptable solution, and SPL will deal
         with such monies as Licensor may lawfully direct at no additional
         out-of-pocket expense to SPL. Notwithstanding the foregoing, if
         royalties in any country cannot be remitted to Licensor for any reason
         within [ * ] after the end of the Calendar Quarter during which they
         are earned, then SPL shall be obligated to deposit the royalties in a
         bank account in such country in the name of Licensor.

         3.7      Maintenance of Records; Audits.

                  (a)      Record Keeping by SPL. SPL and its Affiliates shall
         keep complete and accurate records in sufficient detail to enable the
         royalties payable hereunder to be determined. Upon [ * ] days prior
         written notice from Licensor, SPL shall permit an independent certified
         public accounting firm of nationally recognized standing selected by
         Licensor, at Licensor's expense, to have access during normal business
         hours to examine pertinent books and records of SPL and/or its
         Affiliates as may be reasonably necessary to verify the accuracy of the
         royalty reports hereunder. The examination shall be limited to
         pertinent books and records for any year ending not more than [ * ]
         months prior to the date of such request. An examination under this
         Section 3.7(a) shall not occur more than once in any Calendar Year. SPL
         may designate competitively sensitive information, which such auditor
         may not disclose to Licensor; provided, however, that such designation
         shall not encompass the auditor's conclusions. The accounting firm
         shall disclose to Licensor only whether the royalty reports are correct
         or incorrect and the specific details concerning any discrepancies. No
         other information shall be provided to Licensor. All such accounting
         firms shall sign a confidentiality agreement (in form and


                                       19
<PAGE>   26

         substance reasonably acceptable to SPL) as to any of SPL's or its
         Affiliate's confidential information which they are provided, or to
         which they have access, while conducting any audit pursuant to this
         Section 3.7(a).

                  (b)      Underpayments/Overpayments. If such accounting firm
         correctly concludes that additional royalties were owed during such
         period, SPL shall pay the additional royalties within [ * ] days of the
         date Licensor delivers to SPL such accounting firm's written report so
         correctly concluding. If such underpayment exceeds [ * ] of the royalty
         correctly due Licensor then the fees charged by such accounting firm
         for the work associated with the underpayment audit shall be paid by
         SPL. Any overpayments by SPL will be credited against future royalty
         obligations. In the event that SPL disagrees with the audit report and
         the chief financial officers of SPL and Licensor (or their designees)
         fail to resolve such disagreement, the dispute will be resolved through
         the dispute resolution mechanism set forth in Section 9.2.

                  (c)      Record Keeping by Sublicensee. SPL shall include in
         each sublicense granted by it pursuant to this Agreement a provision
         requiring the Sublicensee to make reports to SPL, to keep and maintain
         records of sales made pursuant to such sublicense and to grant access
         to such records by Licensor's independent accountant to the same extent
         required of SPL under this Agreement.

                  (d)      Confidentiality. Licensor shall treat all financial
         information subject to review under this Section 3.7, or under any
         sublicense agreement, in accordance with the confidentiality provisions
         of this Agreement, and shall cause its accounting firm to enter into an
         acceptable confidentiality agreement with SPL obligating it to retain
         all such financial information in confidence pursuant to such
         confidentiality agreement.

                  (e)      Binding Records. Upon the expiration of [ * ] months
         following the end of any Calendar Year, the calculation of royalties
         payable under this Agreement with respect to such year shall be binding
         and conclusive upon the Parties, and SPL, its Affiliates and its
         Sublicensees shall be released from any liability or accountability
         with respect to royalties for such Calendar Year.


                                       20
<PAGE>   27

         3.8      Income Tax Withholding. If at any time, any jurisdiction
within the Territory requires the withholding of income taxes or other taxes
imposed upon payments set forth in this Article III, SPL shall make such
withholding payments as required and subtract such withholding payments from the
payments set forth in this Article III, or if applicable, Licensor will promptly
reimburse SPL or its designee(s) of the amount of such payments, it being
understood that such withholding taxes are the obligation of Licensor. SPL shall
provide Licensor with documentation of such withholding and payment in a manner
that is satisfactory for purposes of the U.S. Internal Revenue Service. Any
withholdings paid when due hereunder shall be for the account of Licensor and
shall not be included in the calculation of Net Sales. Payments of withholding
taxes made by SPL pursuant to this Section 3.8 will be made based upon financial
information to be provided to SPL by Licensor and, to the extent that such
information is incorrect or incomplete, Licensor shall be liable for any fine,
assessment or penalty, or any deficiency, imposed by any taxing authority in the
Territory for any deficiency in the amount of any such withholding or the
failure to make such withholding payment. If SPL is required to pay any such
deficiency, or any such fine, assessment or penalty for any such deficiency,
Licensor shall promptly reimburse SPL for such payments, which shall not be
included in the calculation of Net Sales.

         3.9      Direct Affiliate Licenses. Whenever SPL shall reasonably
demonstrate to Licensor that, in order to facilitate direct royalty payments by
an Affiliate, it is desirable that a separate license agreement be entered into
between Licensor and such Affiliate, Licensor will grant such licenses directly
to such Affiliate by means of an agreement which shall be consistent with all of
the provisions hereof, provided that SPL guarantees the Affiliate's obligations
thereunder.

                                   ARTICLE IV
                                     PATENTS

         4.1      Filing, Prosecution and Maintenance of Patents. Licensor
agrees to diligently file, prosecute and maintain in the Territory, at
Licensor's expense, all Patent Rights owned in whole or in part by Licensor and
licensed to SPL under this Agreement, including without limitation, any Patent
Rights covering any Improvement(s). SPL shall determine the country(ies) in the
Territory with respect to which SPL desires Licensor to perform such activities
and will promptly notify Licensor to that effect. All such determinations shall
be made by SPL in accordance with its standard practices with respect to the
filing, prosecution and maintenance of patents, and Licensor's obligation to
file, prosecute and maintain each patent application or patent within the Patent
Rights under this Section 4.1 shall be limited to those countries selected by
SPL for such patent application or patent. Licensor shall supply SPL with a copy
of the applications as filed, together with notice of its filing date and serial
number. Licensor shall keep SPL regularly advised of the status of pending
patent applications (including, without limitation, the grant of any Patent
Rights), and upon the written request of SPL shall provide copies of any
substantive papers provided to or received from government patent authorities
related to the filing, prosecution and maintenance of such patent filings. SPL
shall treat all information, papers, and



                                       21
<PAGE>   28

other materials provided by Licensor pursuant to this Section 4.1 in accordance
with the confidentiality provisions of this Agreement.

         4.2      Option of SPL to Prosecute and Maintain Patents. Licensor
shall give [ * ] days prior written notice to SPL of any desire to cease
prosecution and/or maintenance of a particular Patent Right and, in such case,
shall permit SPL, at its sole discretion, to continue prosecution or maintenance
at its own expense. If SPL elects to continue prosecution or maintenance,
Licensor shall execute such documents and perform such acts, at SPL's expense,
as may be reasonably necessary to effect an assignment of such Patent Rights to
SPL. Any such assignment shall be completed in a timely manner to allow SPL to
continue such prosecution or maintenance. Any patents or patent applications so
assigned shall not be considered Patent Rights.

         4.3      Enforcement.

                  (a)      Notice and Discontinuance of Infringement. In the
         event that either SPL or Licensor becomes aware of any third party
         infringement within the Territory of any Valid Claim, it will notify
         the other Party in writing to that effect. Any such notice shall
         include evidence to support an allegation of infringement by such third
         party. Licensor shall have a period of [ * ] months from the date of
         said notice to obtain a discontinuance of such infringement or bring
         suit against the third party infringer. Licensor shall bear all the
         expenses of any suit brought by it. SPL shall have the right, prior to
         commencement of the trial, suit or action brought by Licensor, to join
         any such suit or action, and in such event shall pay one-half of all
         costs of such suit or action. In the event that SPL has joined in the
         action and shared in the costs thereof as set forth above, no
         settlement, consent judgment or other voluntary final disposition of
         the suit may be entered into without the consent of SPL. In the event
         that SPL has not joined the suit or action, SPL will reasonably
         cooperate with Licensor in any such suit or action and shall have the
         right to consult with Licensor and be represented by its own counsel,
         provided that Licensor shall periodically reimburse SPL for its
         out-of-pocket costs (excluding the costs of retaining its own outside
         counsel) incurred in cooperating with Licensor. Any recovery or damages
         derived from any suit under this Section 4.3(a) where SPL has joined
         and shared costs shall be used first to reimburse each of Licensor and
         SPL for its documented out-of-pocket legal expenses relating to the
         suit, shall be used second to reimburse Licensor for royalties lost as
         a result of reduced sales of Licensed Product, shall be used third to
         reimburse SPL for amounts attributed to SPL's lost profits, with any
         remaining amounts, including but not limited to punitive, exemplary, or
         other enhanced damages, to be shared [ * ] by the Parties. Any recovery
         or damages derived from a suit which SPL has not joined shall be
         retained by Licensor.

                  (b)      Continuance of Infringement. If Licensor has neither
         obtained a discontinuance of such infringement nor brought suit against
         such infringer after the expiration of the [ * ] period specified in
         Subsection 4.3(a), SPL shall have the right, but not the obligation, to
         bring suit against such infringer under the Patent Rights and join


                                       22
<PAGE>   29

         Licensor as a party plaintiff, provided that SPL shall bear all the
         expenses of such suit. Licensor shall cooperate with SPL in any such
         suit for infringement of a Patent Right brought by SPL against a third
         party, and shall have the right to consult with SPL and to participate
         in and be represented by independent counsel in such litigation at its
         own expense. SPL shall periodically reimburse Licensor for its out of
         pocket costs (excluding Licensor's costs of retaining independent
         counsel) incurred in cooperating with SPL. SPL shall incur no liability
         to Licensor as a consequence of such litigation or any unfavorable
         decision resulting therefrom, including any decision holding any of the
         Patent Rights invalid or unenforceable, except that SPL shall indemnify
         and hold Licensor harmless for any monetary judgment or award against
         or penalty levied upon either Licensor or SPL arising out of SPL's acts
         in the enforcement of such Patent Rights. In the event that SPL
         recovers any sums through litigation under this Section 4.3(b) by way
         of damages or in settlement thereof, SPL shall retain all such sums.

         4.4      Third Party Infringement Suit.

                  (a)      Defense. In the event that a third party sues SPL
         alleging that SPL's, its Affiliates' or its Sublicensees' making,
         having made, importing, exporting, using, distributing, marketing,
         promoting, offering for sale or selling Licensed Compound and/or
         Licensed Product in one or more countries in the Territory infringes or
         will infringe said third party's patent, then SPL may elect to defend
         such suit at its sole expense and discretion. To the extent that the
         alleged infringement is based upon the use of Licensed Compound,
         another compound from the Compound Library or the Licensor Know-How,
         SPL shall have no obligation to pay royalties to Licensor under Section
         3.3 with respect to sales of Licensed Product in such country(ies)
         during the pendency of any such suit. Upon SPL's request and in
         connection with SPL's defense of any such third party infringement
         suit, Licensor shall cooperate with SPL for such defense provided, that
         SPL shall promptly reimburse Licensor for reasonable out-of-pocket
         costs and expenses incurred by Licensor in providing such cooperation
         (excluding Licensor's costs of retaining independent counsel). Licensor
         shall invoice SPL for such costs and expenses, and shall provide
         documentation for the invoice. The invoice shall be payable to Licensor
         or its designee(s) [ * ] days after receipt by SPL of the invoice.

                  (b)      Licensing. SPL shall have the right to negotiate with
         said third party for a suitable license or assignment of rights under
         the relevant patents. In the event that such negotiation results in a
         consummated agreement, then any lump sum payment and/or royalty
         payments to be made thereunder shall be paid by SPL and shall be offset
         against any royalties due Licensor in accordance with the terms of
         Article 3.4.

         4.5      Certification Under Drug Price Competition and Patent
Restoration Act. Licensor and SPL each shall immediately give written notice to
the other of any certification of which they become aware filed pursuant to 21
U.S.C. ss.355(b)(2)(A)(iv) and 355(j)(2)(A)(vii), or any amendment or successor
statute thereto, claiming that Patent Rights covering Licensed



                                       23
<PAGE>   30

Compound and/or Licensed Product(s) are invalid or that infringement will not
arise from the manufacture, use or sale of a product containing Licensed
Compound or otherwise equivalent to Licensed Product by a third party.
Notwithstanding any provision to the contrary, in the event that the Patent
Rights at issue are owned and/or controlled by Licensor and Licensor has failed
to bring an infringement action against such third party at least [ * ] business
days prior to expiration of the forty five (45) day period set forth in 21
U.S.C. ss.355(c)(3)(C) (or any amendment or successor statute thereto), SPL
shall have the right to bring such an infringement action, in its sole
discretion and at its own expense, in its own name and/or in the name of
Licensor. At SPL's request, Licensor shall, at its own expense, provide SPL
reasonable assistance to conduct such infringement action, including, without
limitation, causing the execution of such legal documents as SPL may deem
necessary for the prosecution of such action. SPL shall periodically reimburse
Licensor for its out-of-pocket costs (excluding any of Licensor's costs of
retaining independent counsel) incurred in assisting SPL. SPL shall incur no
liability to Licensor as a consequence of such litigation or any unfavorable
decision resulting therefrom, including any decision holding any of the Patent
Rights invalid or unenforceable, except that SPL shall indemnify and hold
Licensor harmless for any monetary judgment or award against or penalty levied
upon either Licensor or SPL arising out of SPL's acts in the enforcement of such
Patent Rights. In the event that SPL recovers any sums in such litigation by way
of damages or in settlement thereof, SPL shall have the right to retain all such
sums to offset its costs, losses and expenses.

         4.6      Abandonment. Subject to SPL's rights pursuant to Section 4.2,
Licensor shall at the earliest known date give notice to SPL of the grant,
lapse, revocation, surrender, invalidation or abandonment of any Patent Rights
licensed to SPL for which Licensor is responsible for the filing, prosecution
and maintenance under this Agreement.

         4.7      Patent Term Restoration. The Parties hereto shall cooperate
with each other in obtaining patent term restoration or its equivalent in the
Territory where applicable to Patent Rights. In the event that elections with
respect to obtaining such patent term restoration are to be made, SPL shall have
the right to make the election and Licensor agrees to abide by such election.

         4.8      Notices Regarding Patents. All notices, inquiries and
communications in connection with this Article IV shall be sent in the manner

         disclose to any third party, any of the other Party's Proprietary
         Information received by it pursuant to this Agreement without the prior
         written consent of the other Party. The foregoing obligations shall
         survive the expiration or termination of this Agreement for a period of
         [ * ] years. These obligations shall not apply when and to the extent
         Proprietary Information :

                           (i)      is known by the receiving Party at the time
                  of its receipt, and not through a prior disclosure by the
                  disclosing Party, as documented by business records;

                           (ii)     is at the time of disclosure or thereafter

                           (iii)    is subsequently disclosed to the receiving
                  Party by a third party that has the right to make such
                  disclosure;

                           (iv)     is developed by the receiving Party
                  independently of Proprietary Information or other information
                  received from the disclosing Party and such independent
                  development can be documented by the receiving Party;

                           (v)      is disclosed to any institutional review
                  board of any entity conducting clinical trials, or any
                  governmental or other regulatory agencies in order to obtain
                  patents, to gain approval to conduct clinical trials or to
                  market Licensed Compound and/or Licensed Product, but such
                  disclosure may be made only to the extent reasonably necessary
                  to obtain such patents or authorizations; or

                           (vi)     is required by law, regulation, rule, act or
                  order of any governmental authority or agency to be disclosed
                  by a Party, provided that notice is promptly delivered to the
                  other Party in order to provide an opportunity to seek



                                       25
<PAGE>   32

                  a protective order or other similar order with respect to such
                  Proprietary Information and thereafter the disclosing Party
                  discloses to the requesting entity only the minimum
                  Proprietary Information required to be disclosed in order to
                  comply with the request, whether or not a protective order or
                  other similar order is obtained by the other Party.

         of Section 5.1(a), SPL shall have the right to disclose Licensor's
         Proprietary Information to its Sublicensees, agents, consultants,
         Affiliates or other third parties (collectively "Agents") in accordance
         with this Section 5.1(b). Such disclosure shall be limited only to
         those Agents directly involved in the research, development,
         manufacture, marketing or promotion of Licensed Compound or Licensed
         Product (or for such Agents to determine their interest in performing
         such activities) in accordance with this Agreement. Any such Agents
         must agree in writing to be bound by confidentiality and non-use
         obligations essentially the same as those contained in this Agreement.
         The term of confidentiality and non-use obligations for such Agents
         shall be no less than [ * ] years. SPL shall be jointly and severally
         liable for any disclosure of Licensor Proprietary Information by
         Agents.

                  (c)      Disclosure to a Third Party. Licensor shall have the
         right to use and disclose any Licensor Know-How at its sole option and
         discretion for the limited purpose of filing, prosecuting, and
         supporting Patent Rights. Subject to the terms of Section 5.2, either
         Party may publish Licensor Know-How under the terms of Section 5.3
         below. Licensor shall not otherwise disclose, provide or transfer any
         Licensor Know-How to any third party without the prior written approval
         of SPL.

         5.2      Publicity. Except as provided in Section 5.1 and this Section
5.2, a Party may not use the name of the other Party in any publicity,
advertising or in any other public way and, may not issue press releases or
otherwise publicize or disclose any information related to the existence of this
Agreement, the terms or conditions of this Agreement, or any information
relating to the subject matter hereof, without the prior written consent of the
other Party. The Parties shall agree upon an initial press release to announce
the execution of this Agreement, together with a corresponding Q&A outline for
use in responding to inquiries about the Agreement. Following such initial press
release, Licensor may use the specific information contained therein, or in any
subsequent public announcements or publications made by SPL or by mutual
agreement of the Parties, in Licensor's investor relations and public relations
activities. Licensor shall make no public announcement, either written, oral or
in any medium relating to the safety of Licensed Compound and/or Licensed
Product, except for statements in official correspondence with government patent
authorities in support of Patent Rights as provided for in Section 5.1(c). [ * ]

         5.4      Publication. SPL and Licensor each acknowledge the potential
benefit in



                                       26
<PAGE>   33

publishing results of certain studies to obtain recognition within the
scientific community and to advance the state of scientific knowledge. Each
Party also recognizes the mutual interest in obtaining valid patent protection
and in protecting business interests and trade secret information. No
publication of Licensor Know-How or Patent Rights may be made without the prior
written consent of Licensor. The Parties agree that SPL, its Affiliates,
employees or consultants shall be free to make any publication which does not
disclose Licensor Know-How or Patent Rights. In the event that any proposed
publication (as defined below) discloses Licensor Know-How or Patent Rights, the
following procedure shall apply: Either Party, its Affiliates, employees or
consultants wishing to make a publication shall deliver to the other Party a
copy of the proposed written publication or an outline of an oral disclosure at
least [ * ] days prior to submission for publication or presentation. For
purposes of this Agreement, the term "publication" shall include, without
limitation, abstracts and manuscripts for publication, slides and texts of oral
or other public presentations, and texts of any transmission through any
electronic media, e.g. any computer access system such as the Internet,
including the World Wide Web. The reviewing Party shall have the right (i) to
propose modifications to the publication for patent reasons, trade secret
reasons or business reasons or (ii) to request delay of the publication or
presentation in order to protect patentable information. If the reviewing Party
requests a delay, the publishing Party shall delay submission or presentation
for a period of up to [ * ] from the filing date of the first patent application
in the Territory covering the information contained in the proposed publication
or presentation. If the reviewing Party requests modifications to the
publication, the publishing Party may edit such publication to prevent
disclosure of trade secret or proprietary business information prior to
submission of the publication or presentation.

                  irregularities in connection with the preparation, filing or
                  prosecution of patent applications or patents which may have a
                  material adverse effect with respect thereto; and

         (iv)     knows of no irregularities or information suggesting any
                  irregularities in connection with the conduct and evaluation
                  of the Studies which may have a material adverse effect with
                  respect thereto.

                  (b)      To the extent of Licensor's obligations under this
         Agreement, Licensor shall undertake to perform the following in
         accordance with all applicable laws, rules and regulations:

                  subcontractors, collaborators and/or agents prepare, file,

         application or submission for Regulatory Approval, Licensor shall,

                                   ARTICLE VII
                   INDEMNIFICATION AND LIMITATION ON LIABILITY

         7.1      Indemnification by SPL. SPL shall indemnify, defend and hold
harmless Licensor and its Affiliates, and each of its and their respective
employees, officers, directors and agents (each, a "Licensor Indemnified Party")
from and against any and all third party claims, demands, lawsuits, proceedings,
settlement amounts, liability, loss, damage, cost, and expense (including
reasonable attorneys' fees), (collectively, a "Liability") which may be asserted
against the Licensor Indemnified Party or which the Licensor Indemnified Party
may incur, suffer or be required to pay resulting from or arising out of (i) the
discovery, development, manufacture, promotion, distribution, use, testing,
marketing, sale or other disposition of Licensed Compound



                                       31
<PAGE>   38

and/or Licensed Product(s) by SPL, its Affiliates or Sublicensees (including
without limitation any personal injury, death, or other injuries suffered by
users of Licensed Compound or Licensed Product), or (ii) the breach by SPL of
any covenant, representation or warranty contained in this Agreement; or (iii)
the successful enforcement by a Licensor Indemnified Party of its rights under
this Section 7.1. Notwithstanding the foregoing, SPL shall have no obligation
under this Agreement to indemnify, defend or hold harmless any Licensor
Indemnified Party with respect to any Liability which results from the willful
misconduct or negligent acts or omissions of Licensor, its Affiliates, or any of
their respective employees, officers, directors or agents.

         7.2      Indemnification by Licensor. Licensor shall indemnify, defend
and hold harmless SPL and its Affiliates, and each of its and their respective
employees, officers, directors and agents (each, a "SPL Indemnified Party") from
and against any Liability which the SPL Indemnified Party may incur, suffer or
be required to pay resulting from or arising out of (i) the breach by Licensor
of any covenant, representation or warranty contained in this Agreement; or (ii)
the successful enforcement by a SPL Indemnified Party of its rights under this
Section 7.2. Notwithstanding the foregoing, Licensor shall have no obligation
under this Agreement to indemnify, defend or hold harmless any SPL Indemnified
Party with respect to any Liability which results from willful misconduct or
negligent acts or omissions of SPL, its Affiliates, or any of their respective
employees, officers, directors or agents.

         7.3      Conditions to Indemnification. Each Party agrees to promptly
give the other Party notice of any claim for which indemnification may be
sought. Failure of an indemnified Party to provide notice of a claim to the
indemnifying Party shall affect the indemnified Party's right to indemnification
only to the extent that such failure has a material adverse effect on the
indemnifying Party's ability to defend or the nature or the amount of the
Liability. Subject to the provisions of Article IV, the indemnifying Party shall
have the right to assume the defense of any suit or claim related to the
Liability if it has assumed responsibility for the suit or claim in writing;
provided, however, that if in the reasonable judgment of the indemnified Party,
such suit or claim involves an issue or matter which could have a materially
adverse effect on the business operations or assets of the indemnified Party,
the indemnified Party may waive its rights to indemnity under this Agreement and
control the defense or settlement thereof, but in no event shall any such waiver
be construed as a waiver of any indemnification rights such Party may have at
law or in equity. If the indemnifying Party defends the suit or claim, the
indemnified Party may participate in (but not control) the defense thereof at
its sole cost and expense.

         7.4      Settlements. Subject to the provisions of Article IV, neither
Party may settle a claim or action related to a Liability without the consent of
the other Party if such settlement would impose any monetary obligation on the
other Party or require the other Party to submit to an injunction or otherwise
limit the other Party's rights under this Agreement, provided that such consent
shall not be unreasonably withheld or delayed. Any payment made by a Party to
settle any such claim or action shall be at its own cost and expense.

         7.5      Limitation of Liability. With respect to any claim by one
Party against the other



                                       32
<PAGE>   39

arising out of the performance or failure of performance of the other Party
under this Agreement, the Parties expressly agree that the liability of such
Party to the other Party for such breach shall be limited under this Agreement
or otherwise at law or equity to direct damages only and in no event shall a
Party be liable for, punitive, exemplary or consequential damages suffered or
incurred by the other Party.

         7.6      Insurance. Each Party acknowledges and agrees that during the
Term of this Agreement it shall maintain adequate insurance and/or a
self-insurance program for contractual liability insurance to cover such Party's
obligations under this Agreement. Each Party shall provide the other Party with
evidence of such insurance and/or self-insurance program, upon request.

respect to the applicable product which are granted pursuant to this Agreement

         the unilateral right to terminate this Agreement on a

         commercialization of Licensed Compound or Licensed Product pursuant to
         Sections 2.6(a) and (c), subject to Section 2.6(b). In the event of the
         exercise of such termination rights, the rights and licenses granted to
         SPL under Sections 2.1 and 2.2 shall terminate and all rights to
         Licensor Know-How, Licensed Compounds and Licensed Products with
         respect to the applicable product which are granted pursuant to this
         Agreement shall revert to Licensor.

                  (b)      Termination by Licensor Licensor shall have the
         unilateral right to terminate this Agreement by giving [ * ] days
         written notice to SPL in the event that:

                           (i)      [ * ]

                           (ii)     [ * ]

         In the event of the exercise of such termination rights, the rights and

         8.4      Termination.

                  (a)      Termination for Cause. This Agreement may be
         terminated by written notice at any time during the Term of this
         Agreement:

                           (i)      by either Party, subject to Section 9.2, if
                  the other Party is in breach of its material obligations with
                  respect to such product hereunder and has not cured such
                  breach within [ * ] days ([ * ] days with respect to payment
                  obligations under Article III) after written notice requesting
                  cure of the breach with reasonable detail of the particulars
                  of the alleged breach, or within [ * ] days of receiving
                  notice initiated actions reasonably expected to cure the cited
                  failure and thereafter diligently pursued such actions to cure
                  the failure (even if requiring longer than the [ * ] days set
                  forth in this subsection); or

                           (ii)     by either Party upon the filing or
                  institution of bankruptcy, reorganization (in connection with
                  any insolvency), liquidation or receivership proceedings, or
                  upon an assignment of a substantial portion of the assets for
                  the benefit of creditors by the other Party, or in the event a
                  receiver or custodian is appointed for such other Party's
                  business, or if a substantial portion of such other Party's
                  business is subject to attachment or similar process;
                  provided, however, that in the case of any involuntary
                  bankruptcy proceeding such right to terminate shall only
                  become effective if the proceeding is not dismissed within
                  [ * ] days after the filing thereof.

                  (b)      Effect of Termination for Cause on License.

                           (i)      Termination by SPL. In the event SPL
                  terminates this Agreement under Section 8.4(a)(i), due to a
                  breach by Licensor of its material obligations under Section
                  2.1(a), 2.1(b) or 2.11(a) of this Agreement, then SPL's
                  licenses pursuant to Sections 2.1 and 2.2 shall become fully
                  paid-up, perpetual licenses.


                                       34
<PAGE>   41

                           (ii)     Termination by Licensor. In the event that
                  Licensor terminates this Agreement under Section 8.4(a)(i),
                  then the rights and licenses granted to SPL under Sections 2.1
                  and 2.2 shall terminate and all rights to Licensor Know-How,
                  Licensed Compounds and Licensed Products granted pursuant to
                  this Agreement shall revert to Licensor.

                           (iii)    Effect of Bankruptcy. In the event SPL
                  terminates this Agreement under Section 8.4(a)(ii) or this
                  Agreement is otherwise terminated under Section 8.4(a)(ii),
                  the Parties agree that SPL, as a licensee of rights to
                  intellectual property under this Agreement, shall retain and
                  may fully exercise all of its rights and elections under the
                  Insolvency Statute including as set forth in Section 9.8
                  hereof.

         8.5      Effect of Termination. Expiration or termination of the
Agreement shall not relieve the Parties of any obligation accruing prior to such
expiration or termination, and the provisions of Articles V and VII shall
survive the expiration of the Agreement. With regard to reimbursement for
development costs incurred by Licensor, including, without limitation, the costs
of clinical studies, SPL's obligations under Section 2.6 shall upon termination
be limited to the costs for actual work performed in accordance with the
relevant research plans or protocols up to the effective date of such
termination, or any irrevocable financial commitments made by Licensor prior to
the date of notice of termination. Any expiration or early termination of this
Agreement shall be without prejudice to the rights of either Party against the
other accrued or accruing under this Agreement prior to termination, including
the obligation to pay royalties for Licensed Product(s) or Licensed Compound
sold prior to such termination. In the event of termination of this Agreement,
SPL shall have the right to continue to sell its existing inventory of Licensed
Product during the [ * ] month period immediately following such termination,
provided that SPL shall continue to make royalty payments with respect to such
sales.

         8.6      Remedies for Breach. In addition to any and all other
remedies that SPL may have under this Agreement, or otherwise under law and/or
equity, in the event that Licensor materially breaches its obligations under
Sections 6.6(a) or (b) of this Agreement and/or materially breaches its
representation, warranties and covenants under Section 6.2(m), then SPL shall
have the right, at SPL's sole discretion, upon written notice to Licensor to
either: (i) deduct [ * ] of the remaining unpaid milestone(s) in Section 3.2;
(ii) permanently reduce by [ * ] the royalty rates provided for in Section 3.3;
or (iii) immediately terminate the Agreement.

         8.7      Licensor's Rights on Termination. In the event that Licensor
terminates this Agreement under Section 8.3 or 8.4(a)(i), or SPL terminates this
Agreement under Section 8.2 or 8.3, SPL shall provide to Licensor the following:

         (i)      all existing Regulatory Approvals and/or applications for
                  Regulatory Approval for the applicable Licensed Product(s) in
                  the Territory;

         (ii)     access, including the right to make copies, of all
                  preclinical, clinical,



                                       35
<PAGE>   42

                  pharmacokinetic, toxicology or other data owned or controlled
                  by SPL which is necessary to support any of the Regulatory
                  Approvals provided to Licensor under Section 8.7(i);

         (iii)    subject to the terms of Section 8.7 (iv), all preclinical and
                  clinical supplies of the applicable Licensed Product(s),
                  and/or Licensed Compound or other Compound Library compounds,
                  in SPL's possession or control;

         (iv)     access to all manufacturing information relating to the
                  Licensed Product, including assigning, sublicensing or
                  otherwise making available, as appropriate, any third party
                  manufacturing agreements relied upon by SPL for the
                  manufacture of Licensed Product, in each case to the extent
                  reasonably necessary for Licensor to manufacture the Licensed
                  Product following such termination;

         (v)      to the extent that termination occurs after the First
                  Commercial Sale of the applicable Licensed Product(s) and
                  subject to the terms of Section 8.5, Licensor shall have the
                  right to purchase SPL's remaining inventory of the applicable
                  Licensed Product(s) and/or Licensed Compound or other Compound
                  Library compounds for sale in the Territory at [ * ] of SPL's
                  fully absorbed manufacturing costs.

In addition, in the event of such termination, SPL shall grant to Licensor a
paid-up, non-exclusive, non-transferable license in the Territory under any
issued patents, or pending patent applications, owned or controlled by SPL which
would otherwise be infringed by the manufacture, use or sale of the applicable
Licensed Product(s) in the Territory, which license shall be restricted to the
sole purpose of making, having made, importing, exporting, using, distributing,
marketing, promoting, offering for sale and selling such Licensed Product(s).

         8.8      Concurrent Termination with the US Agreement. In the event of
any termination of the US Agreement by either Licensor or Schering Corporation
under the provisions of Sections 8.2, 8.3 or 8.4 of the US Agreement, this
Agreement shall automatically terminate concurrently under the corresponding
Section 8.2, 8.3 or 8.4 of this Agreement.


                                   ARTICLE IX
                                  MISCELLANEOUS

         9.1      Assignment/Change of Control.

                  (a)      Assignment. Neither this Agreement nor any or all of
         the rights and obligations of a Party hereunder shall be assigned,
         delegated, sold, transferred, sublicensed (except as expressly
         permitted hereunder) or otherwise disposed of, by operation of law or
         otherwise, to any third party (other than an Affiliate of an assigning
         Party under the condition that the assignor remain responsible to the
         other Party under



                                       36
<PAGE>   43

         this Agreement), without the prior written consent of the other Party.
         Any attempted assignment, delegation, sale, transfer, sublicense or
         other disposition, by operation of law or otherwise, of this Agreement
         or of any rights or obligations hereunder contrary to this Section 9.1
         shall be a material breach of this Agreement by the attempting Party,
         and shall be void and without force or effect; provided, however,
         either Party may, without such consent, assign the Agreement and its
         rights and obligations hereunder to an Affiliate or in connection with
         the transfer or sale of all or substantially all of its assets related
         to the division or the subject business, or in the event of its merger
         or consolidation or change in control or similar transaction. This
         Agreement shall be binding upon, and inure to the benefit of, each
         Party, its Affiliates, and its permitted successors and assigns. Each
         Party shall be responsible for the compliance by its Affiliates with
         the terms and conditions of this Agreement.

                  (b)      Change of Control. In the event the ownership or
         control of Licensor is acquired by another pharmaceutical company that
         has an ongoing development program or commercializes (directly or
         through any Affiliate) any compound or product for the Primary
         Indication and/or the Secondary Indication, Licensor shall promptly
         notify SPL in writing to that effect. Licensor's obligations under
         Section 2.11 shall not extend to any such compound or product.
         Effective upon such notice, the JMC shall be disbanded and SPL will
         assume and thereafter be responsible for all of the rights and
         obligations of the JMC. Licensor, and following the change of control
         the acquiring party, shall use best efforts to ensure that such
         acquiring party does not have any access to any of SPL's Proprietary
         Information or other proprietary information relating to the
         development and commercialization of Licensed Product. Such best
         efforts shall include, without limitation: (i) ensuring that the
         acquiring party does not have access to any such information prior to
         the change of control of Licensor; and (ii) promptly destroying or
         returning to SPL all such information in Licensor's possession or
         control upon completion of the change of control. The acquiring party
         shall have no rights to use any Licensor Know-How relating to the
         Primary Indication or the Secondary Indication in connection with the
         development and commercialization of its own compound or product for
         the Primary and/or Secondary Indication. All of SPL's obligations under
         Article II to provide Licensor and/or the JMC with reports or to
         otherwise keep Licensor informed with respect to the development and
         commercialization of Licensed Compound, any other compound within the
         Compound Library and/or Licensed Product shall immediately terminate;
         provided, however, that SPL shall provide such acquiring party with an
         annual summary of its activities in developing and commercializing
         Licensed Product.

         9.2      Governing Law. This Agreement shall be governed, interpreted
and construed in accordance with the laws of the State of New Jersey, without
giving effect to conflict of law principles. All disputes under this Agreement
shall be governed by binding arbitration pursuant to the mechanism set forth in
Schedule 9.2 attached hereto and incorporated hereby. The Parties expressly
exclude application of the United Nations Convention for the International Sale
of Goods.

         9.3      Waiver. Any delay or failure in enforcing a Party's rights
under this Agreement or any waiver as to a particular default or other matter
shall not constitute a waiver of such Party's rights to the future enforcement
of such rights under this Agreement, nor operate to bar the exercise or
enforcement thereof at any time or times thereafter, excepting only as to an
express written and signed waiver as to a particular matter for a particular
period of time.

         9.4      Independent Relationship. Nothing in this Agreement shall be
deemed to create an employment, agency, joint venture or partnership
relationship between the Parties hereto or any of their respective Affiliates,
agents or employees, or any other legal arrangement that would impose liability
upon one Party for the act or failure to act of the other Party. Neither Party
shall have any power to enter into any contracts or commitments or to incur any
liabilities in the name of, or on behalf of, the other Party, or to bind the
other Party in any respect whatsoever.

         9.5      Export Control. This Agreement is made subject to any
restrictions concerning the export of products or technical information from the
United States of America which may be imposed upon or related to Licensor or SPL
from time to time by the government of the United States of America.
Furthermore, SPL agrees that it will not export, directly or indirectly, any
technical information acquired from Licensor under this Agreement or any
products using such technical information to any country for which the United
States government or any agency thereof at the time of export requires an export
license or other governmental approval, without first obtaining the written
consent to do so from the Department of Commerce or other agency of the United

9.8      Provisions for Insolvency.

                  (a)      Effect on Licenses. All rights and licenses granted
         under or pursuant to this Agreement by Licensor to SPL are, for all
         purposes of Section 365(n) of Title 11 of the United States Code
         (together with its foreign equivalent, the "Insolvency Statute"),
         licenses of rights to "intellectual property" as defined in the
         Insolvency Statute. Licensor agrees that SPL, as licensee of such
         rights under this Agreement shall retain and may fully exercise all of
         its rights and elections under the Insolvency Statute provided that SPL
         makes all royalty payments under this Agreement. Licensor agrees during
         the Term of this Agreement to create and maintain current copies or, if
         not amenable to copying, detailed descriptions or other appropriate
         embodiments, to the extent feasible, of all such intellectual property.
         If a case is commenced by or against Licensor under the Insolvency
         Statute, Licensor (in any capacity, including debtor-in-possession) and
         its successors and assigns (including, without limitation, an
         Insolvency Statute trustee) shall,

                           (i)      as SPL may elect in a written request,
                  immediately upon such request:

                                    (A)      perform all of the obligations
                           provided in this Agreement to be performed by
                           Licensor including, where applicable and without
                           limitation, providing to SPL portions of such
                           intellectual property (including embodiments thereof)
                           held by Licensor and such successors and assigns or
                           otherwise available to them; or

                                    (B)      provide to SPL all such
                           intellectual property (including all embodiments
                           thereof) held by Licensor and such successors and
                           assigns or otherwise available to them; and

                           (ii)     not interfere with the rights of SPL under
                  this Agreement, or any agreement supplemental hereto, to such
                  intellectual property (including such embodiments), including
                  any right to obtain such intellectual property (or such
                  embodiments) from another entity.

                  (b)      Rights to Intellectual Property. If an Insolvency
         Statute case is commenced by or against Licensor, and this Agreement is
         rejected as provided in the Insolvency Statute, and SPL elects to
         retain its rights hereunder as provided in the Insolvency Statute, then
         Licensor (in any capacity, including debtor-in-possession) and its
         successors and assigns (including, without limitation, an Insolvency
         Statute trustee) shall provide to SPL all such intellectual property
         (including all embodiments thereof) held by Licensor and such
         successors and assigns, or otherwise available to them, immediately
         upon SPL's written request. Whenever Licensor or any of its successors
         or assigns provides to SPL any of the intellectual property licensed
         hereunder (or any embodiment thereof) pursuant to this Section 9.8, SPL
         shall have the right to perform the obligations


                                       40
<PAGE>   47

         of Licensor hereunder with respect to such intellectual property, but
         neither such provision nor such performance by SPL shall release
         Licensor from any such obligation or liability for failing to perform
         it.

                  (c)      SPL's Rights. All rights, powers and remedies of SPL
         provided herein are in addition to and not in substitution for any and
         all other rights, powers and remedies now or hereafter existing at law
         or in equity (including, without limitation, the Insolvency Statute) in
         the event of the commencement of an Insolvency Statute case by or
         against Licensor. SPL, in addition to the rights, power and remedies
         expressly provided herein, shall be entitled to exercise all other such
         rights and powers and resort to all other such remedies as may now or
         hereafter exist at law or in equity (including, without limitation, the
         Insolvency Statute) in such event. The Parties agree that they intend
         the foregoing SPL rights to extend to the maximum extent permitted by
         law, including, without limitation, for purposes of the Insolvency
         Statute:

                           (i)      the right of access to any intellectual
                  property (including all embodiments thereof) of Licensor, or
                  any third party with whom Licensor contracts to perform an
                  obligation of Licensor under this Agreement, and, in the case
                  of the third party, which is necessary for the development,
                  registration, manufacture and marketing of Licensed Compound
                  and/or Licensed Product(s); and

                           (ii)     the right to contract directly with any
                  third party described in (i) to complete the contracted work.

                  (d)      Deemed Grant of Rights. In the event of any
         insolvency of Licensor and if any statute and/or regulation in any
         country in the Territory requires that there be a specific grant or
         specific clause(s) in order for SPL to obtain the rights and benefits
         as licensee under this Agreement which are analogous to those rights
         under Section 365(n) of Title 11 of the United States Code, then this
         Agreement shall be deemed to include any and all such required
         grant(s), clause(s) and/or requirements.

                  (e)      Security Interests. In addition to any other rights
         granted to SPL hereunder, with respect to any country in the Territory
         in which SPL reasonably determines that its rights set forth in this
         Section 9.8 are nonexistent or inadequate to protect SPL's interests in
         the licenses granted hereunder, Licensor shall, upon SPL's request,
         execute a security agreement, or any foreign equivalent, for each
         country in the Territory, granting SPL a secured interest in all
         intellectual property licensed to SPL under this Agreement.

         9.9      Force Majeure. Failure of any Party to perform its obligations
under this Agreement (except the obligation to make payments when properly due)
shall not subject such Party to any liability or place them in breach of any
term or condition of this Agreement to the other Party if such failure is due to
any cause beyond the reasonable control of such non-performing Party ("force
majeure"), unless conclusive evidence to the contrary is provided. Causes of
non-performance constituting force majeure shall include, without limitation,
acts of God, fire, explosion, flood, drought, war, riot, sabotage, embargo,
strikes or other labor trouble, failure in whole or in part of suppliers to
deliver on schedule materials, equipment or machinery, interruption of or delay
in transportation, a national health emergency or compliance with any order or
regulation of any government entity acting with color of right. The Party
affected shall promptly notify the other Party of the condition constituting
force majeure as defined herein and shall exert reasonable efforts to eliminate,
cure and overcome any such causes and to resume performance of its obligations
with all possible speed; provided, however, that nothing contained herein shall
require any Party to settle on terms unsatisfactory to such Party any strike,
lock-out or other labor difficulty, any investigation or proceeding by any
public authority, or any litigation by any third party. If a condition
constituting force majeure as defined herein exists for more than ninety (90)
consecutive days, the Parties shall meet to negotiate a mutually satisfactory
resolution to the problem, if practicable.

         9.10     Severability. If any provision of this Agreement is declared
illegal, invalid or unenforceable by a court having competent jurisdiction, it
is mutually agreed that this Agreement shall endure except for the part declared
invalid or unenforceable by order of such court; provided, however, that in the
event that the terms and conditions of this Agreement are materially altered,
the Parties will, in good faith, renegotiate the terms and conditions of this
Agreement to reasonably substitute such invalid or unenforceable provisions in
light of the intent of this Agreement.

         9.11     Counterparts. This Agreement shall become binding when any one
or more counterparts hereof, individually or taken together, shall bear the
signatures of each of the Parties hereto. This Agreement may be executed in any
number of counterparts, each of which shall be an original as against either
Party whose signature appears thereon, but all of which taken together shall
constitute but one and the same instrument.

         9.12     Captions. The captions of this Agreement are solely for the
convenience of reference and shall not affect its interpretation.

         9.13     Recording. Each Party shall have the right, at any time, to
record, register, or otherwise notify this Agreement in appropriate governmental
or regulatory offices anywhere in the world, and each Party shall provide
reasonable assistance to the other in effecting such recording, registering or
notifying. Notwithstanding the foregoing, prior to recording, registering, or
otherwise notifying this Agreement, the Party desiring to so record, register,
or notify shall provide a copy of all materials to be filed for review, comment,
and approval by the other Party, such approval not unreasonably to be withheld
or delayed.

         9.14     Further Actions. Each Party agrees to execute, acknowledge and
deliver such further instruments, and to do all other acts, as may be necessary
or appropriate in order to carry out the purposes and intent of this Agreement
including, without limitation, any filings with any antitrust agency which may
be required.

         IN WITNESS WHEREOF, this Agreement has been executed by the duly
authorized representatives of the Parties as of the date set forth below.

             Elements of Fully Absorbed Manufacturing Cost of Goods

The following expenses are included in manufacturing costs:

1.       Direct Materials

completed product, such as:

         -        Inert raw materials or excipients
         -        Active substances/ingredients
         -        Packaging components such as bottles, caps, labels, etc.

2.       Direct Labor

The cost of employees engaged in production activities that are directly
identifiable with product costs. Excludes supervision, which is included in
indirect labor, and production support activities such as inspection, plant and
equipment maintenance labor, and material handling personnel. Direct Labor cost
includes:

         -        Base pay, overtime, vacation and holidays, illness, personal
                  time with pay and shift differential.

3.       Indirect Manufacturing Costs

Costs which are ultimately allocated to product based on standard direct labor
hours of the operating departments. These costs include:

         -        Indirect Production Labor - salaries of employees engaged in
                  production activities who are not classified as direct labor,
                  including supervision, clerical, etc.

         -        Costs of Direct Labor - employees not utilized for the
                  manufacturing of product such as training, downtime and

                  property (manufacturing site, buildings and the fixed assets
                  of equipment, furniture and fixtures, etc.). If manufacturing
                  site includes other operations (marketing, R&D, etc.), taxes
                  are allocated to manufacturing on the basis of total real and

         services rendered, EDP computer hours, etc.

4.       Quality Assurance Costs

Direct labor and indirect costs for Quality Assurance departments testing and
approving materials used in manufacturing and completed manufacturing batches
and finished products. This includes all manufacturing in-process testing and
testing of finished materials. Excluded from product costs are QA costs related
to research and development, stability testing, and other costs customarily
excluded from such Quality Assurance costs.

The following expenses are not included in manufacturing costs:
         a)       Inventory Carrying Costs
         b)       Regulatory Affairs Costs
         c)       Pilot plant costs, research batches and other similar costs
                  prior to turnover to manufacturing. These are handled as
                  development costs and expensed to R&D. This excludes
                  commercial goods produced by a research facility.
         d)       Costs incurred by Manufacturing for special projects (e.g.
                  requests by Schering-Plough Research Institute) to establish
                  and certify new production processes, batch sizes and product
                  line improvements, and new vendor certification of equipment
                  and primary materials components.
                  These costs are expensed to R&D.
         e)       Manufacturing start-up costs and initial one-time
                  extraordinary manufacturing costs incurred prior to plant
                  operation and achievement of a normal production activity
                  level. Includes costs of training, testing,
                  qualification/validation of new equipment and facilities and
                  initial, trial batches. These costs are deferred and then
                  amortized to Other Production Costs over five years.
         f)       Significant idle capacity is eliminated from factory overhead
                  and product cost. Idle or excess capacity costs are culled out
                  of the Manufacturing Budget and expensed as a period cost to
                  Other Production Costs.
         g)       Finished goods warehousing, shipping and other distribution
                  costs. These are included in distribution costs.
         h)       Product liability and/or business interruption insurance
                  expenses.
         i)       Intercompany profit.

5.       Other Production Costs

Three major types of expense are included in the Other Production Costs
classification.

         a)       Variances from standard cost the difference between the actual
                  and standard cost of inventory purchased and produced during
                  the period less any portion applicable to on-hand inventory
                  which has been capitalized.

                  (i)      Materials purchase price variance


                                      iii
<PAGE>   53

                  (ii)     Materials usage/yield variances
                  (iii)    Direct labor efficiency/inefficiency - reflects the
                           cost difference between the standard and actual
                           number of direct labor hours used for actual
                           production.
                  (iv)     Overhead - reflects all other labor and overhead cost
                           variances including activity and spending production
                           related and support.

                  With the exception of overhead, all of the other variances can
                  be identified by product and can be added (if unfavorable) or
                  subtracted (if favorable) to determine actual manufacturing
                  costs of a product.

         (b)      Non-standard costs: Cost of miscellaneous production related
                  operations for which standards are not established due to the
                  nature of the function, such as manufacturing start-up
                  operations, stock conversions and reclaiming (processing and
                  returning to finished goods inventory) of products returned by
                  customers. Also includes miscellaneous expenses incurred in
                  connection with the production of inventory which for various
                  reasons (e.g., cyclical, non-recurring) are not included in
                  standard costs. Examples include excess/idle capacity not
                  included in standards, abnormal waste or rework, experiments,
                  unallocated production costs, tooling and package design
                  costs.

                  Some of the above costs may be incurred for specific products,
                  e.g., rework, experiments, tooling, but the majority are
                  general to all products produced.

         (c)      Inventory adjustments: Consists of charges or credits due to
                  adjustments to inventory concerning revaluation to new
                  standards, stock conversions, capitalized/amortized production
                  variances, shortages or overages, and damage or obsolescence
                  of regular on-hand inventory or products returned by
                  customers.

Each of these charges or credits can be identified to a specific product.

                 ADVERSE EVENT REPORTING PROCEDURES FOR PRODUCTS


         The Parties understand and agree that these procedures are intended to
comply with 21 CFR 314.80(b) and 21 CFR 310.305(a) concerning standard written
procedures for adverse event reporting in the United States. These procedures
may be amended by the Parties at any time, at the request of either Party, to
ensure that they fully and accurately reflect the procedures in place for
surveillance, receipt, evaluation and reporting of adverse drug experiences by
the pharmacovigilance departments of the Parties and comply with applicable laws
and regulations in the countries in which the product(s) is marketed and/or is
under investigation. In that regard, upon the written request of either Party,
the Parties shall meet to renegotiate in good faith, all or some of these
procedures. Each Party may request such a meeting no more often than once in any
twelve (12) month period.


1.       Definitions:

         (a)      An Adverse Event ("AE") is defined as:

                  i)       any experience which is adverse, including what are
                           commonly described as adverse or undesirable
                           experiences, adverse events, adverse reactions, side
                           effects, or death due to any cause associated with,
                           or observed in conjunction with the use of a drug,
                           biological product, or device in humans, whether or
                           not considered related to the use of that product:

                           -        occurring in the course of the use of a
                                    drug, biological product or device,

                           -        associated with, or observed in conjunction
                                    with product overdose, whether accidental or
                                    intentional,

                           -        associated with, or observed in conjunction
                                    with product abuse,

                           -        associated with, or observed in conjunction
                                    with product withdrawal

                  ii)      Any significant failure of expected pharmacological
                           or biologic therapeutical action (with the exception
                           of in clinical trials).

         (b).     Associated with or related to the use of the drug is defined
as: A


<PAGE>   58

reasonable possibility exists that the AE was caused by the drug.

         (c)      Expected or unexpected are defined as:

                  i)       Expected ("labeled") AE - An AE which is included in
                           the Investigators' Brochure for clinical trials,
                           included in local labeling (e.g., summary of product
                           characteristics) for Marketed Drugs, or in countries
                           with no local labeling, in the Company Core Data
                           Sheet (CCDS).


                  ii)      Unexpected ("unlabeled") AE - An AE that does not
                           meet the criteria for an expected AE or an AE which
                           is listed but differs from that event in terms of
                           severity or specificity.

         (d)      IND Holder is defined as: A "Sponsor" as defined in 21 CFR
Part 312.2(b) of an investigational new drug in any regulatory jurisdiction,
including a holder of a foreign equivalent thereto.

         (e)      Life-threatening is defined as: any adverse drug experience
that places the patient, in the view of the initial reporter, at immediate risk
of death from the adverse drug experience as it occurred, i.e., it does not
include an AE that, had it occurred in more severe form, might have caused
death.

         (f)      NDA Holder is defined as: An "Applicant" as defined in 21 CFR
Part 314.3(b), for regulatory approval of a Licensed Product in any regulatory
jurisdiction, including a holder of a foreign equivalent thereto.

         (g)      Serious or Non-Serious are defined as:

                  i)       Any adverse drug experience occurring at any dose
                           that results in any of the following outcomes: Death,
                           a life-threatening adverse drug experience, inpatient
                           hospitalization or prolongation of existing
                           hospitalization, a persistent or significant
                           disability/incapacity, or a congenital anomaly/birth
                           defect. Important medical events that may not result
                           in death, be life-threatening, or require
                           hospitalization may be considered serious when, based
                           upon appropriate medical judgment, they may
                           jeopardize the patient or subject and may require
                           medical or surgical intervention to prevent one of
                           the outcomes listed in this definition. Examples of
                           such medical events include allergic bronchospasm
                           requiring intensive treatment in an emergency room or
                           at home, blood dyscrasias or convulsions that do not
                           result in inpatient hospitalization, or the
                           development of drug dependency or drug abuse.

<PAGE>   59

                  ii)      A Non-serious AE is any AE which does not meet the
                           criteria for a serious AE.

         (h)      Not associated or unrelated to the use of the drug means it
does not meet the definition of "associated."

2.       Capitalized terms not defined in this Appendix shall have the meaning
         assigned thereto in the Agreement.

3.       With respect to all Licensed Products:

                  All initial reports (oral or written) for any and all serious
                  AEs as defined above which become known to either Party (other
                  than from disclosure by or on behalf of the other Party) must
                  be communicated by telephone, telefax or electronically
                  directly to the other Party, NDA Holder, and/or IND Holder
                  (individually and collectively referred to as "Holders")
                  within five (5) calendar days of receipt of the information.
                  Written confirmation of the Serious AE received by the Party
                  should be sent to the other Party and the Holders as soon as
                  it becomes available, but in any event within two (2) business
                  days of initial report of the Serious AE by such Party.

                  All Parties and Holders should exchange Medwatch and/or CIOMS
                  forms and other health authority reports within two (2)
                  business days of submission to any regulatory agency.

                  All initial reports and follow-up information received for all
                  non-serious AEs for marketed Licensed Products which become
                  known to a Party (other than from disclosure by or on behalf
                  of the other Party) must be communicated in writing, by
                  telefax or electronically to the other Party and all Holders
                  on a monthly basis, on Medwatch or CIOMs forms (where
                  possible). All follow-up on any AE reports forwarded to either
                  Party by FDA must be submitted to FDA.

                  Each Party shall coordinate and cooperate with the other
                  whenever practicable to prepare a single written report
                  regarding all Serious AEs, provided, however, that neither
                  Party shall be obligated to delay reporting or any AE in
                  violation of applicable law or regulations regarding the
                  reporting of adverse events.

4.       The Parties further agree that:

         (a)      a written report for AEs for animal studies which suggest a
potential significant risk for humans shall be forwarded to the other Party
within two (2) business days of receipt by the Party making the report,

<PAGE>   60
 (b)      each Party will give the other Party a print-out or computer disk of
all AEs reported to it relating to Products within the preceding 365
days/calendar year, within [ * ] days of receipt of a request from the other
Party;

         (c)      upon request of a Party, the other Party shall make available
its AE records relating to Licensed Products (including computer disks) for
viewing and copying by the other Party,

         (d)      disclosure of information hereunder by a Party to the other
Party shall continue as long as either Party continues to clinically test or
market product(s) containing Licensed Products or holds an open IND, NDA or
foreign equivalent thereto.

         (e)      all written regulatory reports, including periodic NDA, annual
IND, safety updates, or foreign equivalents thereto, etc. should be sent by a
Party to the other Party within 2 business days of submission to the appropriate
regulatory agency. The Parties shall agree on a procedure for preparing these
reports (e.g. electronic mail, facsimile transmission, overnight service, etc.).

5.       Each Party shall diligently undertake the following further obligations
where both Parties are or will be commercializing products hereunder and/or
performing clinical trials with respect to Licensed Product:

         (a)      to immediately consult with the other Party, with respect to
the investigation and handling of any serious AE disclosed to it by the other
Party or by a third Party, including government agencies, and to allow the other
Party to review the serious AE and to participate in the follow-up
investigation;

         (b)      to immediately advise the other Party of any Product safety
communication received from a health authority and consult with the other Party
with respect to any proposed change to product warnings, labeling or an
Investigator's Brochure involving safety issues, including, but not limited to,
safety issues agreed to by the Parties;

         (c)      to diligently handle in a timely manner the investigation and
resolution of each AE reported to it; and

         (d)      to provide the other Party reasonable annual audit rights of
its AE reporting system and documentation, upon prior notice, during normal
business hours, at the expense of the auditing Party and under customary
confidentiality obligations.

         (e)      to meet in a timely fashion from time to time as may be
reasonably required to implement the adverse event reporting and consultation
procedures described in this Appendix, including identification of those
individuals in each Party's pharmacovigilance group who will be responsible for
reporting to and receiving AE information from the other Party, and the
development of a written standard operating

procedure with respect to adverse event reporting responsibilities, including
reporting responsibilities to investigators;

         (f)      where possible, to transmit all data electronically;

         (g)      to report to each other any addenda, revisions or changes to
this Agreement (e.g., change in territories, local regulations, addition of new
licensors/licensees to the agreement, etc.) which might alter the adverse event
reporting responsibilities hereunder;

         (h)      to utilize English as the language of communication and data
exchange between the Parties;

         (i)      to develop a system of exchange of documents and information
in the event that the Agreement involves more than two Holders.

                             ARBITRATION PROVISIONS

         (a) Scope. Subject to and in accordance with the terms of this
Agreement and this Schedule 9.2, all differences, disputes, claims or
controversies arising out of or in any way connected or related to this
Agreement, whether arising before or after the expiration of the Term of this
Agreement, and including, without limitation, its negotiation, execution,
delivery, enforceability, performance, breach, discharge, interpretation and
construction, existence, validity and any damages resulting therefrom or the
rights, privileges, duties and obligations of the Parties under or in relation
to this Agreement (including any dispute as to whether an issue is arbitrable)
shall be referred to binding arbitration in accordance with the rules of the
American Arbitration Association, as in effect at the time of the arbitration.

         (b) Parties to Arbitration. For the purposes of each arbitration under
this Agreement, SPL shall constitute one party to the arbitration and Licensor
shall constitute the other party to the arbitration.

         (c) Notice of Arbitration. A Party requesting arbitration hereunder
shall give a notice of arbitration to the other Party containing a concise
description of the matter submitted for arbitration, including references to the
relevant provisions of the Agreement and a proposed solution (a "Notice of
Arbitration"). Notice of Arbitration shall be delivered to the other Party in
accordance with Section 9.7 of the Agreement.

         (d) Response. The non-requesting Party must respond in writing within
forty-five (45) days of receiving a Notice of Arbitration with an explanation,
including references to the relevant provisions of the Agreement and a response
to the proposed solution and suggested time frame for action. The non-requesting
Party may add additional issues to be resolved.

         (e) Meeting. Within fifteen (15) days of receipt of the response from
the non-requesting Party pursuant to Paragraph (d), the Parties shall meet and
discuss in good faith options for resolving the dispute. The requesting Party
must initiate the scheduling of this resolution meeting. Each Party shall make
available appropriate personnel to meet and confer with the other Party during
such fifteen-(15) day period.

         (f) Selection of Arbitrator. Any and all disputes that cannot be
resolved pursuant to Paragraphs (c), (d) and (e) shall be submitted to an
arbitrator (the "Arbitrator") to be selected by mutual agreement of the Parties.
The Arbitrator shall be a retired judge of a state or federal court, to be
chosen from a list of such retired judges to be prepared jointly by the Parties,
with each Party entitled to submit the names of three such retired judges for
inclusion in the list. No Arbitrator appointed or selected hereunder shall be an
employee, director or shareholder of, or otherwise have any current or previous
relationship with, any Party or its respective Affiliates. If the Parties fail
to

agree on the selection of the Arbitrator, the Arbitrator shall be designated by
a judge of the Federal District Court in New York upon application by either
Party.

         (g) Powers of Arbitrator. The Arbitrator may determine all questions of
law and jurisdiction (including questions as to whether a dispute is arbitrable)
and all matters of procedure relating to the arbitration. The Arbitrator shall
have the right to grant legal and equitable relief (including injunctive relief)
and to award costs (including reasonable legal fees and costs of arbitration)
and interest. Nothing contained herein shall be construed to permit the
Arbitrator to award punitive, exemplary or any similar damages.

         (h) Arbitration Procedure. In the event that SPL is the Party
requesting arbitration, the arbitration shall take place in the State of
Georgia, unless otherwise agreed by the Parties, at such place and time as the
Arbitrator may fix for the purpose of hearing the evidence and representations
that the Parties may present. In the event that Licensor is the Party requesting
arbitration, the arbitration shall take place in the State of New Jersey, unless
otherwise agreed by the Parties, at such place and time as the Arbitrator may
fix for the purpose of hearing the evidence and representations that the Parties
may present. The arbitration proceedings shall be conducted in the English
language. The law applicable to the arbitration shall be the law of the State of
New Jersey. No later than twenty (20) business days after hearing the
representations and evidence of the Parties, the Arbitrator shall make its
determination in writing and deliver one copy to each of the Parties.

         (i) Discovery and Hearing. During the meeting referred to in Paragraph
(e), the Parties shall negotiate in good faith the scope and schedule of
discovery, relating to depositions, document production and other discovery
devices, taking into account the nature of the dispute submitted for resolution.
If the Parties are unable to reach agreement as to the scope and schedule of
discovery, the Arbitrator may order such discovery as it deems necessary. To the

               LICENSE; DISCLOSURE OF INFORMATION; DEVELOPMENT AND
                               COMMERCIALIZATION

         2.1      Exclusive License Grant.

                  (a) License. Subject to the terms and conditions of this
         Agreement, Licensor hereby grants to Schering, as of the Effective
         Date, an exclusive license (exclusive even as to Licensor) under the
         Patent Rights and Licensor Know-How in the Territory to develop, make,
         have made, import, export, use, distribute, market, promote, offer for
         sale and sell: (i) Licensed Compound(s) and/or Licensed Product(s)
         containing Licensed Compound; and (ii) compound(s) in the Compound
         Library other than Licensed Compound, and/or Licensed Product(s)
         containing such compound(s) for the Primary Indication and the
         Secondary Indication.

                  (b) Co-Exclusive License to Other Indications Subject to the
         terms and conditions of this Agreement, Licensor hereby grants to
         Schering, as of the Effective Date, a co-exclusive license under the
         Patent Rights and Licensor Know-How in the Territory to develop, make,
         have made, import, export, use, distribute, market, promote, offer for
         sale and sell compound(s) in the Compound Library other than Licensed
         Compound, and/or Licensed Product(s) containing


                                       6
<PAGE>   80

         such compound(s), for any and all indications other than the Primary
         Indication and Secondary Indication. The term "co-exclusive license"
         shall mean that with respect to the rights granted to Schering under
         this Section 2.1(b), Licensor retains the same rights as are granted to
         Schering. With respect to a given compound, indication or territory,
         each of Licensor and Schering may either directly exercise and exploit
         its co-exclusive rights or grant a co-exclusive license under such
         rights, either in whole or in part, to one (1) third party or
         Affiliate.

                  (c) Right to Sublicense. The licenses granted to Schering
         under Sections 2.1(a) and 2.1(b) shall include the right to grant
         sublicenses to Affiliates and/or any third party (to the extent
         provided therein), provided that Schering remains responsible to
         Licensor under this Agreement for the performance of its Sublicensees.

                  (d) Retained Rights Subject to the restrictions set forth in
         Section 2.11, Licensor retains all rights under the Patent Rights not
         expressly granted to Schering by this Section 2.1, and the right to use
         Licensor Know-How pursuant to Sections 2.6(h) and 5.1(c) below.

                  (e) Third Party Agreements. As of the Execution Date, Licensor
         is a party to certain agreements (as listed in Schedule 2.1(e),
         redacted copies of which have been provided to Schering) with third
         parties pursuant to which Licensor has acquired rights to certain
         patent applications, patents and technology, which agreements are
         relevant to the Patent Rights and/or Licensor Know-How. The parties
         acknowledge that the licenses granted to Schering under this Agreement
         are subject to the specific rights retained by or granted to the U.S.
         Government, and/or the rights for research use retained by such third
         parties, under those agreements. In the event that on or after the
         Execution Date and during the Term of this Agreement, Licensor acquires
         any additional Patent Rights or Licensor Know-How from any third
         parties, by assignment, license or otherwise, Licensor shall promptly
         notify Schering in writing to that effect, and provide Schering with a
         copy (which may be redacted) of the agreement(s) with such third party.
         To the extent that the copies of the agreements listed in Schedule
         2.1(e) which were provided to Schering, or any other agreements
         provided to Schering under this Section 2.1(e), have been redacted,
         Licensor represents and warrants that the redacted portions of such
         agreements have no material effect on the scope of the licenses or
         other rights granted to Schering under this Agreement. Nothing herein
         shall be construed as granting to Schering any greater rights under the
         Patent Rights and/or Licensor Know-How than those held by Licensor

         2.2 Non-Exclusive License Grant. In the event that the development,
making, having made, importing, exporting, use, distribution, marketing,
promotion, offering for sale or sale by Schering, its Affiliates and/or
Sublicensees of Licensed Product in the Territory would infringe during the Term
of this Agreement a claim of an issued letters patent, and/or any patent rights
which Licensor owns or has the rights to license and


                                       7
<PAGE>   81
which patents are not covered by the grant in Section 2.1, Licensor hereby
grants to Schering and its Affiliates, to the extent Licensor is legally able to
do so, a non-exclusive, royalty-free license in the Territory under such issued
letters patent solely for Schering, its Affiliates and/or Sublicensees to
discover, develop, make, have made, use, distribute, market, promote, offer for
sale and sell Licensed Compound and/or Licensed Product(s) in the Territory.

         2.3 Disclosure of Information. Promptly after the Effective Date,
Licensor shall, at its own cost, disclose to Schering in writing, or via
mutually acceptable electronic media, copies or reproductions of all existing
Licensor Know-How not previously disclosed to Schering in order to enable
Schering to exploit its rights granted under Section 2.1 and, if applicable,
Section 2.2 of this Agreement. In addition, during the Term of this Agreement,
Licensor shall promptly disclose to Schering in writing, or via mutually
acceptable electronic media, on an ongoing basis copies or reproductions of all
new Licensor Know-How that is reasonably necessary for research, development,
registration, manufacture, marketing, use or sale of Licensed Compound and/or
Licensed Product. Such Licensor Know-How and other information shall be
automatically deemed to be within the scope of the licenses granted herein
without payment of any additional compensation. Upon Schering's request but
reasonably subject to Licensor's other business requirements, Licensor shall
provide reasonable technical assistance to enable Schering to utilize such
additional Licensor Know-How, provided, that Schering shall promptly reimburse
Licensor for reasonable out-of-pocket costs and expenses incurred by Licensor in
providing such technical assistance. Licensor shall invoice Schering for such
costs and expenses, and shall provide documentation for the invoice. The invoice
shall be payable to Licensor or its designee(s) [ * ] days after receipt by
Schering of the invoice provided, however, that such cost and out-of-pocket
expenses must be identified prior to being committed to by Licensor and provided
to Schering to determine whether Schering agrees to have the technical
assistance provided at such cost and the final amount sought to be reimbursed
shall not exceed [ * ] of the estimated cost without Schering's prior written
consent. Schering shall be under no obligation to reimburse Licensor for
out-of-pocket costs and expenses incurred by Licensor without Schering's
agreement. Schering shall have the right to use for all purposes in connection
with obtaining any Regulatory Approval for the Licensed Product(s) all Licensor
Know-How and other information, disclosed pursuant to this Section and under
this Agreement.

         2.4      HSR Filing and Approvals.

                  (a) HSR Filing. To the extent necessary, each of Licensor and
         Schering shall file, within ten (10) days after the date of this
         Agreement, with the Federal Trade Commission (the "FTC") and the
         Antitrust Division of the United States Department of Justice (the
         "Antitrust Division") any notification and report form (the "Report")
         required of it in the reasonable opinion of either or both Parties
         under the HSR Act with respect to the transactions as contemplated
         hereby and shall cooperate with the other Party to the extent necessary
         to assist the other Party in the preparation of its Report and to
         proceed to obtain necessary approvals


                                       8
<PAGE>   82

         under the HSR Act, including but not limited to the expiration or
         earlier termination of any and all applicable waiting periods required
         by the HSR Act.

                  (b) Licensor's Obligations. Licensor shall use good faith
         reasonable efforts to assist Schering in eliminating any concern on the
         part of any court or government authority regarding the legality of the
         proposed transaction, including, if required by federal or state
         antitrust authorities, Schering's promptly taking all reasonable steps
         to secure government antitrust clearance. Licensor shall cooperate in
         good faith at its own cost with any government investigation and
         promptly produce documents and information demanded by a second request
         for documents and of witnesses if requested.

                  (c) Additional Approvals. Each of Licensor and Schering will
         cooperate and use all reasonable efforts to make all other
         registrations, filings and applications, to give all notices and to
         obtain as soon as practicable all governmental or other consents,
         transfers, approvals, orders, qualifications authorizations, permits
         and waivers, if any, and to do all other things reasonably necessary or
         desirable in Schering's opinion for the consummation of the
         transactions as contemplated hereby (including, without limitation,
         those acts required to obtain necessary approvals under any foreign
         equivalent antitrust statute to the HSR Act or regulation from any
         government or regulatory authority having the requisite jurisdiction;
         provided, however, that Schering shall promptly reimburse Licensor for
         reasonable out-of-pocket costs and expenses incurred by Licensor in
         providing such cooperation. Licensor shall invoice Schering for such
         costs and expenses, and shall provide supporting documentation for the
         invoice. The invoice shall be payable to Licensor or its designee(s)
         [ * ] days after receipt by Schering of the invoice.

         2.5 Joint Management Committee. The Parties shall establish a Joint
Management Committee (the "JMC") to oversee the development and
commercialization program for Licensed Product for the Primary Indication and
the Secondary Indication, and to facilitate the exchange of information between
the Parties. The JMC will generally serve in an advisory capacity with respect
to the development and commercialization activities to be performed by Schering
under this Agreement, with Schering retaining final decision making authority
with respect to all such matters.

                  (a) Composition of the JMC. The JMC shall be composed of up to
         three (3) representatives from each of Schering and Licensor, and a
         quorum shall consist of at least one (1) JMC representative from each
         Party. In any matter before the JMC, each Party shall have one (1)
         vote, with decisions being made by unanimous decision. Schering shall
         seriously consider the recommendations and decisions of the JMC. A
         Party's representatives to the JMC shall serve at the discretion of
         such Party and may be substituted for or replaced at any time by such
         Party. The JMC shall be chaired by a representative of Schering. The
         Chairperson shall be responsible for calling meetings, preparing
         agendas and




                                       9
<PAGE>   83

         preparing and issuing minutes of each meeting within [ * ] days
         thereafter.

                  (b) JMC Meetings. The JMC shall meet at least once each
         Calendar Quarter during the Term of this Agreement, until such time as
         the Parties agree to a more or less frequent meeting schedule. The site
         of such meetings shall alternate between the offices of Schering and
         Licensor (or any other site mutually agreed upon by the Parties) and
         each Party shall bear its own costs of attending such meetings. All
         meetings of the JMC shall be summarized in writing and sent to both
         Parties and countersigned by both Parties.

                  (c) JMC Responsibilities. The JMC will be generally
         responsible for monitoring the status of Schering's development and
         commercialization activities with respect to Licensed Product and for
         preparing recommendations for implementation by Schering with regard
         to: (i) selection of Licensed Compounds for development by Schering as
         Licensed Products for the Primary Indication; (ii) preclinical and
         clinical development plans; (iii) development timelines and scheduling;
         (iv) strategies for obtaining and maintaining Regulatory Approvals; (v)
         marketing and sales strategies for Licensed Product.

                  (d) Deadlock. In the event that the JMC is unable to reach a
         decision by unanimous vote with respect to any matter, then Schering
         shall have final decision making authority with respect thereto.


         2.6      Schering's Development Obligations.

                  (a) Schering Diligence. Schering shall, at Schering's expense,
         and subject to Licensor's compliance with its obligations under
         Sections 2.3 and 2.4, use good faith reasonable efforts to develop,
         obtain Regulatory Approval for, and commercialize the Licensed
         Product(s) in the Territory for the Primary Indication. Schering shall
         have the option, in its sole discretion, to seek Regulatory Approval
         for the Licensed Product for any additional indications it determines
         are desirable, but shall have no diligence obligations to Licensor with
         respect thereto with the exception of those expressly set forth in
         Section 2.11(d). The Parties acknowledge and agree that all business
         decisions including, without limitation, decisions relating to
         Schering's research, development, registration, manufacture, sale,
         commercialization, design, price, distribution, marketing and promotion
         of Licensed Products covered under this Agreement, shall be within the
         sole discretion of Schering. Licensor acknowledges that Schering is in
         the business of developing, manufacturing and selling pharmaceutical
         products and, subject to the provisions of this Section, nothing in
         this Agreement shall be construed as restricting such business or
         imposing on Schering the duty to market and/or sell and exploit
         Licensed Compound or Licensed Product for which royalties are payable
         hereunder to the exclusion of, or in preference to, any other product,
         or in any way other than in accordance with its normal commercial
         practices.



                                       10
<PAGE>   84

                  (b) Opportunity to Cure. If, in Licensor's reasonable opinion,
         Schering fails to comply with any of its diligence obligations under
         Sections 2.6(a) and (c), then Licensor shall have the right to give
         Schering written notice thereof stating in reasonable detail the
         particular failure(s). Schering shall have a period of [ * ] days from
         the receipt of such notice to correct the failure or, in the event that
         the failure cannot be reasonably cured within a [ * ] day period, then
         Schering shall initiate actions reasonably expected to cure the failure
         within [ * ] days of receiving notice and shall thereafter diligently
         pursue such actions to cure the failure (even if requiring longer than
         the [ * ] days specified in Section 8.4(a)(i)). In the event of a
         dispute as to whether or not Schering has failed to exercise due
         diligence under Sections 2.6(a) and 2.6(c), or whether Schering is
         diligently pursuing actions reasonably expected to cure such failure
         under this Section 2.6(b), such dispute shall be resolved through
         binding arbitration in accordance with Section 9.2.

                  (c) Research and Development Activities. As of the Effective
         Date, Schering shall be responsible, at its cost and expense, and in
         its sole judgment, for all research and development activities which
         are necessary to obtain Regulatory Approval for a Licensed Product in
         the Territory for the Primary Indication and any post-approval studies
         required as a condition of obtaining any Regulatory Approval for a
         Licensed Product for the Primary Indication. The parties acknowledge
         and agree that Schering's obligations under this Section 2.6(c) shall
         include all of the costs of conducting the CART Study (whether incurred
         before or after the Effective Date) which are estimated at [ * ]. In
         addition, Schering shall be responsible for any other studies (or
         portions of studies) necessary or desirable, in its sole judgment, for
         maintaining any Regulatory Approval (for the Primary Indication or any
         other indication for which Schering, in its sole discretion, may decide
         to seek Regulatory Approval) in the Territory, as well as any
         pre-marketing studies prior to such Regulatory Approval and
         post-marketing studies conducted following a Regulatory Approval.

                  (d) Licensed Product Registrations; Pricing Reimbursement
         Approvals. Subject to its diligence obligations set forth in Section
         2.6(a), Schering shall be responsible, at its cost and expense, and in
         its sole judgment, for determining the appropriate regulatory strategy,
         for obtaining and maintaining all Regulatory Approvals and for
         obtaining and maintaining any pricing and reimbursement approvals
         required for the sale of Licensed Product in the Territory. Each
         Regulatory Approval and each pricing and reimbursement approval shall
         be placed in Schering's name or the name of a Schering Affiliate unless
         applicable law requires, or Licensor and Schering otherwise agree, that
         an approval be solely or jointly in the name of Licensor or a
         designated Licensor Affiliate. Licensor agrees that notwithstanding
         such Regulatory Approval or pricing and reimbursement approval in its
         name, Schering retains the exclusive rights to make, have made, import,
         export, use, distribute, promote, offer for sale




                                       11

         and sell Licensed Compound and/or Licensed Product(s) as granted
         Schering in Section 2.1.

                  (e) Data. Schering shall own all data arising out of studies
         performed by or on behalf of Schering under this Article II.

                  (f) Assistance by Licensor. In connection with any NDA, HRD or
         other application for Regulatory Approval relating to Licensed Product,
         Licensor shall, at Schering's request, provide to Schering in a prompt
         manner responses to questions which have been raised by any regulatory
         authority in connection with such application for Regulatory Approval
         and further provide to Schering estimates of Licensor's [ * ] costs for
         rendering such assistance. Licensor shall assist Schering from time to
         time, at Schering's request, in the design and implementation of
         clinical studies. Subject to Licensor's rights under Section 3.3(b),
         Licensor shall assist Schering to enable Schering to self-source bulk
         material for the manufacture of Licensed Compound and/or Licensed
         Product; provided, however, that Schering shall have no obligation
         whatsoever to purchase any bulk material or Licensed Compound from
         Licensor.

                  (g)      Reimbursement of Costs by Schering

                           (i)  Schering shall reimburse Licensor for its
                  reasonable [ * ] costs and expenses incurred in rendering
                  assistance under Section 2.6(f) (but no more than [ * ] of
                  those costs which Licensor estimated, as provided above, that
                  the work would cost unless Schering provides written
                  approval). Licensor shall invoice Schering for such costs and
                  expenses, and shall provide documentation for the invoice. The
                  invoice shall be payable to Licensor or its designee(s) [ * ]
                  days after receipt by Schering of the invoice, provided,
                  however, that Schering shall be under no obligation to
                  reimburse Licensor for [ * ] costs and expenses incurred by
                  Licensor without Schering's agreement.

                           (ii) Schering shall reimburse Licensor for its
                  reasonable [ * ] costs and expenses incurred in performing
                  research and development activities under Section 2.6 (h) (but
                  no more than [ * ] of those costs which Licensor estimated, as
                  provided below, that the work would cost unless the JMC
                  provides written approval). Licensor shall invoice Schering
                  for such costs and expenses, and shall provide documentation
                  for the invoice. The invoice shall be payable to Licensor or
                  its designee(s) [ * ] days after receipt by Schering of the
                  invoice, provided, however, that Schering shall be under no
                  obligation to reimburse Licensor for research and development
                  costs and expenses incurred by Licensor without the prior
                  approval of the JMC.



                                       12

         (h) Licensor's Additional Development Obligations. In addition to
Licensor's obligations under Section 2.6(f), the JMC will assign to Licensor the
responsibility to conduct, on Schering's behalf and at Schering's expense,
certain of the research and development activities, including clinical studies
involving Licensed Product, for which Schering is responsible under Section
2.6(c). The nature and extent of the research and development activities to be
conducted by Licensor is generally set forth in Schedule 2.6(h). The JMC shall
determine the specific aspects of such activities, including the timing and
costs of the work to be performed by Licensor. Licensor agrees to use good faith
reasonable efforts to complete such activities in the manner determined by the
JMC, and shall have the right to utilize contract research organizations and
other third party contractors in the performance of such activities, provided
that Licensor shall remain responsible for the performance of all such
contractors. To the extent that Licensor utilizes third party contractors to
perform such activities, Licensor shall enter into suitable agreements with such
contractors, which agreements shall incorporate provisions consistent with the
terms and conditions of this Agreement, including, without limitation,
provisions governing confidentiality, ownership of data, inventions and other
intellectual property arising from such activities, financial obligations and
termination rights. Licensor shall keep the JMC informed with regard to such
third party contracts and shall provide Schering with a copy of all such
agreements. Any research and development activities conducted by Licensor or its
contractors pursuant to this Section 2.6(h) shall be performed in accordance
with good laboratory practices and good clinical practices, and in compliance
with all applicable laws, rules and regulations in the U.S. and the EU, and
shall meet current regulatory standards. Schering shall promptly notify Licensor
in the event that Schering reasonably determines that all or any part of the
work performed by Licensor and/or its contractors under this Section 2.6(h)
fails to meet such standards. If Licensor reasonably disagrees with such
determination, the parties shall refer the matter to an independent expert
(selected by mutual agreement of the parties) to determine whether or not the
study must be repeated to support Regulatory Approval for Licensed Product. In
the event that Licensor and/or the independent expert agrees with Schering's
determination and such studies are repeated, then Schering shall have the right
to deduct the [ * ] costs of repeating such work from the [ * ] payments due
Licensor under this Agreement.

         (i) Adverse Event Reporting Licensor shall promptly report to Schering
any information regarding adverse events related to the use of the Licensed
Product in accordance with the Adverse Event Reporting Procedures (as may be
amended from time to time upon mutual agreement) set forth in Schedule 2.6(i)
and incorporated herein by reference. To the extent that Licensor holds any INDs
or otherwise has any adverse event reporting obligations with respect to
Licensed Product, Schering shall promptly report to Licensor any information
regarding adverse events related to the use of Licensed Product in accordance
with such Adverse Event Reporting Procedures.





                                       13

         2.7  Independent Discoveries by Schering. Licensor acknowledges that
Schering and/or its Affiliates have ongoing research programs which may now or
in the future independently discover, develop and/or acquire technologies and/or
products relating to treatment and prevention of any disease, disorder or
condition in humans or animals. Licensor agrees that such technologies and
products, to the extent discovered without use of Licensor Know-How, will not be
deemed to be Licensor Know-How and are outside the scope of this Agreement.

         2.8  Excused Performance. In addition to the provisions of Article
VIII and Section 9.9, the obligations of Schering with respect to a Licensed
Product under Sections 2.6(a), 2.6(c), 2.6(d) and 2.11(d) are expressly
conditioned upon the continuing absence of any adverse condition or event which
warrants a delay in commercialization of a Licensed Product including, but not
limited to, an adverse condition or event relating to the safety or efficacy of
a Licensed Product or unfavorable labeling, pricing or pricing reimbursement
approvals, or lack of Regulatory Approval, and the obligation of Schering to
develop or market any such Licensed Product shall be delayed or suspended so
long as in Schering's reasonable opinion any such condition or event exists.

         2.9  Supply of Licensed Compound/Licensed Product. Licensor shall be
responsible, at Licensor's expense, for supplying Schering with Licensed
Compound (in the form of bulk active), from Licensor's existing inventory of
Licensed Compound, to enable Schering to perform [ * ], for such Licensed
Compound for the Primary Indication. In addition, Licensor has the limited
option to supply all of Schering's requirements of Licensed Products as set
forth in Section 3.3(b). All Licensed Compound to be supplied by Licensor
hereunder shall be delivered FCA (Kenilworth, New Jersey) (Incoterms 1990) via a
carrier to be specified by Schering. Licensor warrants and represents that all
supplies of Licensed Compound provided to Schering by Licensor shall conform to
the applicable specifications for such Licensed Compound and were prepared in
accordance with current Good Manufacturing Practices ("cGMPs") and other
applicable federal, national, state and local laws and regulations in effect at
the time of manufacture. Schering shall be responsible for the formulation and
packaging of the Licensed Compound provided by Licensor hereunder, and for
manufacture and supply of all Licensed Compound and/or Licensed Product
necessary for the performance of [ * ] and for supplying all commercial
quantities of Licensed Compound and Licensed Products. Licensor shall transfer
to Schering all Licensor Know-How relating to the manufacture of Licensed
Compound, and at Schering's request and expense shall provide reasonable
technical support to facilitate the implementation of such manufacturing
technology at Schering.

         2.10 Reports. Schering shall provide Licensor with quarterly reports of
the status of the research and development activities and progress of any
application for Regulatory Approval, as applicable, in connection with Licensed
Product in the Territory. Further, Schering shall inform Licensor of
commencement, completion, and results of the major phases of clinical
development of Licensed Product, including but not limited to Phase II and Phase
III clinical trials, NDA and HRD submissions, NDA and HRD filings,


                                       14

approvable and approval letters, and launch.

         2.11 Non-Compete Provision. Subject to the terms of Section 9.1(b),
Licensor and its Affiliates shall be subject to the non-compete obligations set
forth in this Section 2.11.

                  (a) During the Term of this Agreement, Licensor shall not
         undertake a development program for, or commercialize, either on its
         own or in collaboration with any third party:

                  [  *  ]

                  [  *  ]

                  [  *  ]

                  (b) For the period extending from the Effective Date until the
         earlier of [ * ] years after the First Commercial Sale of Licensed
         Product in the Territory or [ * ], licensor shall not, either on its
         own or in collaboration with any third party:

                  [ * ]

                  [ * ]

                  (c) The foregoing notwithstanding, Licensor shall at all times
         retain the right to develop and commercialize topical products
         containing any compound other than the Licensed Compound for the
         treatment or prevention of dermatological conditions, diseases or
         disorders. In addition, Licensor shall have the right at all times to
         enter into agreements with third parties relating to the performance by
         Licensor of pre-clinical research activities with respect to compounds
         owned or controlled by such third parties, provided that such compounds
         do not compete through the same mechanism of action with the Licensed
         Compound (as determined using the same criteria as set forth in Section
         6.2(k)) with respect to the Primary Indication and/or the Secondary
         Indication.

                  (d) Licensor's non-compete obligations under Section
         2.11(b)(ii) are expressly conditioned upon Schering's initiating a
         development program for Licensed Product for the Secondary indication
         within [ * ] years after the Effective Date, and thereafter using good
         faith reasonable efforts to develop and commercialize one or more
         Licensed Products for the Secondary Indication.

                                   ARTICLE III
                         PAYMENTS; ROYALTIES AND REPORTS

         3.0 Coordination of Payments under the International Agreement. The
license fee, milestone payments and royalties payable by Schering under this
Article III are in consideration for the rights and licenses granted to Schering
under this Agreement and are in addition to any amounts payable to Licensor
under the International Agreement. It is understood and agreed that, with
respect to the development milestone payable under Section 3.2(a)(i) and the
sales milestones payable under Section 3.2(b) the occurrence of one or more of
such milestone events will result in milestone payment obligations under both
this Agreement and the corresponding provisions of the International Agreement.
It is further understood that Schering's financial obligations with respect to
development costs under Article II shall be [ * ] apportioned between Schering
and the corresponding obligations of Schering-Plough Ltd. under the
International Agreement.

         3.1 License Fee. In partial consideration for the licenses and other
rights granted to Schering hereunder, Schering shall pay to Licensor a license
fee ("License Fee") of [ * ], which payment shall be due within [ * ] business
days following the Effective Date.

         3.2 Milestone Payments. In partial consideration for the licenses and
other rights granted to Schering hereunder, Schering shall promptly notify
Licensor in writing upon the occurrence of an event triggering one of the
milestone payments set forth in this Section 3.2, and within [ * ] days after
the occurrence of such event pay to Licensor the applicable milestone payment.

             (a)      Development Milestones:

                      (i)   [  *  ]

                      (ii)  [  *  ]

                      (iii) [  *  ]

             (b)      Sales Milestones:

                      (i)   [  *  ]

                      (ii)  [  *  ]

                      (iii) [  *  ]

                      (iv)  [  *  ]


                                       16
<PAGE>   90

         The foregoing sales milestone payments are in addition to any royalty
         payments due Licensor under Section 3.3 with respect to sales of
         Licensed Product. For purposes of clarity, the parties acknowledge that
         (1) the first achievement of more than one of the above sales
         milestones in the same Calendar Year shall not affect Schering's
         obligation to make the relevant sales milestone payments to Licensor,
         and (2) annual worldwide sales of the Licensed Product shall be
         determined based upon the aggregate total of sales in the Territory
         under this Agreement and sales in countries outside the Territory under
         the International Agreement.

                  (c) Limitations. Except as expressly set forth below, each
         development milestone payment under Section 3.2(a) and each sales
         milestone payment under Section 3.2(b) shall be payable one (1) time
         only on the first occurrence of the indicated event regardless of the
         number of times the event triggering the payment of such milestone
         occurs. The development milestone payment set forth in Section
         3.2(a)(iii) for U.S. Regulatory Approval of a Licensed Product shall be
         payable for the first Licensed Product developed by Schering and
         thereafter shall again be payable for each successive Licensed Product
         successfully developed by Schering which contains as the active
         ingredient a different compound from the Compound Library. For purposes
         of clarity and avoidance of doubt, the parties acknowledge that
         development milestone 3.2(a)(iii) will not be triggered by repeated
         occurrences of that milestone event involving different Licensed
         Products containing the same compound from the Compound Library. If the
         triggering event for a given milestone payment does not occur prior to
         the effective date of termination, or the expiration, of this
         Agreement, Schering shall have no obligation to pay such milestone
         payment to Licensor. The Parties acknowledge and agree that nothing
         herein shall be construed as representing an estimate or projection of
         anticipated sales or the actual value of Licensed Compounds or Licensed
         Products, and the figures set forth in Section 3.2(b) are merely
         intended to define Schering's obligations to Licensor in the event such
         sales performance is achieved.

         3.3 Royalties. In further consideration for the licenses granted to
Schering hereunder, for so long as the Licensed Product is covered by a Valid
Claim in the Territory at the time of sale by Schering, and subject to the
provisions of Section 3.3 (a)-(c), Schering shall pay to Licensor royalties on a
country-by-country basis of [ * ] of Schering's, its Affiliates' or its
Sublicensees' Net Sales of Licensed Product in the Territory. With respect to
countries in the Territory where no such Valid Claim exists, the royalty rate
shall be [ * ], and such royalties shall be paid for [ * ] years from the first
commercial sale of Licensed Product in such country. No royalties shall be due
upon the sale or other transfer among Schering, its Affiliates or Sublicensees,
but in such cases the royalty shall be due and calculated upon Schering's or its
Affiliates' or its Sublicensees' Net Sales to the first independent third party.
No royalties shall accrue on the disposition of Licensed Product by Schering,
its Affiliates or Sublicensees as samples (promotion or otherwise) or as
donations (for example, to non-profit institutions or government agencies for a
non-commercial purpose) or for clinical studies. Such




                                       17
<PAGE>   91
dispositions by Schering shall not be included in the determination of Net Sales
during the period of time in which such third party sales are occurring.

                  (a) Cap on Royalties Plus Cost of Goods. The parties
         acknowledge and agree that the total of (i) royalties payable by
         Schering to Licensor under this Agreement, and (ii) the Cost of Goods
         of Licensed Product manufactured by Schering and/or paid by Schering to
         third parties for the manufacture of Licensed Product, shall not exceed
         [ * ] of Net Sales of Licensed Product. Schering shall use good faith
         reasonable efforts to keep the Cost of Goods of Licensed Product from
         exceeding [ * ] of Net Sales. Schering shall determine the Cost of
         Goods for the Licensed Product in a timely manner, and in no event
         later than [ * ]. In the event that notwithstanding such efforts by
         Schering the Cost of Goods for Licensed Product does exceed [ * ] of
         Net Sales, then Schering shall notify Licensor in writing to that
         effect. Following receipt of such notice, Licensor shall have the right
         to have an independent auditor review Schering's relevant records and
         make an independent determination of the Cost of Goods for the Licensed
         Product. Any such audit shall be conducted under terms and conditions
         essentially the same as those set forth in Section 3.7.

                  (b) Licensor's Option to Manufacture. In the event that
         Schering's Cost of Goods for the Licensed Product is correctly
         determined to exceed [ * ] of Net Sales, Licensor shall have the right
         to manufacture and supply, or to seek a third party supplier able to
         manufacture and supply, Schering's requirements of Licensed Product at
         a Cost of Goods equal to or less than [ * ] of Net Sales for Licensed
         Product. If Licensor is able, or locates a third supplier able, to
         manufacture and supply Licensed Product at a Cost of Goods equal to or
         less than [ * ] of Net Sales, Schering shall in good faith negotiate
         and enter into a suitable supply agreement with Licensor or such third
         party, as appropriate, for the manufacture and supply of Licensed
         Product. Any such agreement shall include terms obligating Schering to
         purchase, and Licensor or the third party to manufacture and supply,
         all of Schering's requirements of Licensed Product at a Cost of Goods
         to be agreed upon, not to exceed [ * ] of Net Sales of Licensed
         Product. All supplies of Licensed Product to be provided to Schering by
         Licensor or such third party manufacturer pursuant to this Section
         3.3(b) shall be manufactured at a qualified manufacturing site, shall
         conform to the applicable specifications for Licensed Product and shall
         be prepared in accordance with cGMPs and all applicable federal,
         national, state and local laws and regulations in effect at the time of
         manufacture.

                  (c) Royalty Reduction. In the event that Schering's Cost of
         Goods for Licensed Product are correctly determined to exceed [ * ] of
         Net Sales of Licensed Product and Licensor is unable to identify a
         third party capable of supplying Schering's requirements of Licensed
         Product at a price equal to or less than [ * ] of Net Sales of Licensed
         Product, then Schering shall remain responsible for the manufacture and
         supply of Licensed Product and the royalty


                                       18
<PAGE>   92

         rate to be paid by Schering under this Section 3.3 shall be reduced so
         that the total of (i) royalties payable by Schering to Licensor under
         this Agreement, and (ii) the Cost of Goods of Licensed Product
         manufactured by Schering and/or paid by Schering to third parties for
         the manufacture of Licensed Product, is equal to [ * ] of Net Sales of
         Licensed Product. Notwithstanding the foregoing, the royalty payable to
         Licensor under this Agreement shall not be reduced pursuant to this
         Section 3.3(c) to less then [ * ] where a Valid Claim exists, or [ * ]
         where no Valid Claim exists.

         3.4 Third Party Licenses. In the event that Schering's outside patent
counsel determines that patent licenses from third parties are required by
Schering, its Affiliates or its Sublicensees in order to discover, develop,
make, have made, import, export, use, distribute, promote, market, offer for
sale or sell Licensed Compound and/or Licensed Product (hereinafter "Third Party
Licenses"), Schering shall provide Licensor with written notice to that effect
and shall be solely responsible for acquiring such licenses at Schering's sole
discretion. Schering may reduce any royalty otherwise due Licensor hereunder to
reimburse it for royalties and or license fees actually paid to such third
parties under any Third Party Licenses of patent claims which would be infringed
by the manufacture, use, import, export or sale of Licensed Compound and/or
Licensed Product in the Territory. Schering shall have no right to reduce any
royalty due Licensor hereunder for any amounts paid to a third party under any
Third Party License to the extent it is a license to technology (other than
Licensor Know-How) or materials (other than Licensed Compound) selected by
Schering for use in connection with the Licensed Product. The amount of
reduction of royalties due Licensor and the amount of reimbursement to Schering
shall be equal to [ * ] of the royalties or license fees paid to such third
parties in consideration for the Third Party License but in no event shall the
royalty due Licensor for any Licensed Product in any country be thereby reduced
to less than [ * ] of the royalty rate otherwise due Licensor hereunder for such
Licensed Product in such country.

         3.5 Compulsory Licenses. If a compulsory license is granted under the
Patent Rights to a third party with respect to Licensed Compound and/or Licensed
Product in any country in the Territory with a royalty rate lower than the
royalty rate provided for under Section 3.3, then the royalty rate to be paid by
Schering on Net Sales in that country under Section 3.3 shall be reduced to the
rate paid by the compulsory licensee for so long as such compulsory license is
in effect.

         3.6 Reports; Payment of Royalty; Payment Exchange Rate and Currency
Conversions.

             (a) Royalties Paid Quarterly. Within [ * ] calendar days
         following the close of each Calendar Quarter, following the First
         Commercial Sale of a Licensed Product, Schering shall furnish to
         Licensor a written report for the Calendar Quarter showing the Net
         Sales of Licensed Product(s) sold by Schering, its Affiliates and its
         Sublicensees in the Territory during such Calendar


                                       19
<PAGE>   93

         Quarter and the royalties payable under this Agreement for such
         Calendar Quarter. Simultaneously with the submission of the written
         report, Schering shall pay to Licensor, for the account of Schering or
         the applicable Affiliate or Sublicensee, as the case may be, a sum
         equal to the aggregate royalty due for such Calendar Quarter calculated
         in accordance with this Agreement (reconciled for any previous
         overpayments or underpayments).

             (b) Method of Payment. Payments to be made by Schering to
         Licensor under this Agreement shall be paid by bank wire transfer in
         immediately available funds to such bank account as is designated in
         writing by Licensor from time to time. Royalties shall be deemed
         payable by the entity making the Net Sales from the country in which
         earned in local currency and subject to foreign exchange regulations
         then prevailing. Royalty payments shall be made in United States
         dollars to the extent that free conversions to United States dollars is
         permitted. The rate of exchange to be used in any such conversion from
         the currency in the country where such Net Sales are made shall be the
         rate of exchange used by Schering Corporation for reporting such sales
         for United States financial statement purposes. If, due to restrictions
         or prohibitions imposed by national or international authority,
         payments cannot be made as aforesaid, the Parties shall consult with a
         view to finding a prompt and acceptable solution, and Schering will
         deal with such monies as Licensor may lawfully direct at no additional
         out-of-pocket expense to Schering. Notwithstanding the foregoing, if
         royalties in any country cannot be remitted to Licensor for any reason
         within [ * ] months after the end of the Calendar Quarter during which
         they are earned, then Schering shall be obligated to deposit the
         royalties in a bank account in such country in the name of Licensor.

         3.7     Maintenance of Records; Audits.

                 (a) Record Keeping by Schering. Schering and its Affiliates
         shall keep complete and accurate records in sufficient detail to enable
         the royalties payable hereunder to be determined. Upon [ * ] days prior
         written notice from Licensor, Schering shall permit an independent
         certified public accounting firm of nationally recognized standing
         selected by Licensor, at Licensor's expense, to have access during
         normal business hours to examine pertinent books and records of
         Schering and/or its Affiliates as may be reasonably necessary to verify
         the accuracy of the royalty reports hereunder. The examination shall be
         limited to pertinent books and records for any year ending not more
         than [ * ] months prior to the date of such request. An examination
         under this Section 3.7(a) shall not occur more than once in any
         Calendar Year. Schering may designate competitively sensitive
         information, which such auditor may not disclose to Licensor; provided,
         however, that such designation shall not encompass the auditor's
         conclusions. The accounting firm shall disclose to Licensor only
         whether the royalty reports are correct or incorrect and the specific
         details concerning any discrepancies. No other information shall be
         provided to


                                       20
<PAGE>   94


         Licensor. All such accounting firms shall sign a confidentiality
         agreement (in form and substance reasonably acceptable to Schering) as
         to any of Schering's or its Affiliate's confidential information which
         they are provided, or to which they have access, while conducting any
         audit pursuant to this Section 3.7(a).

                  (b) Underpayments/Overpayments. If such accounting firm
         correctly concludes that additional royalties were owed during such
         period, Schering shall pay the additional royalties within [ * ] days
         of the date Licensor delivers to Schering such accounting firm's
         written report so correctly concluding. If such underpayment exceeds
         [ * ] of the royalty correctly due Licensor then the fees charged by
         such accounting firm for the work associated with the underpayment
         audit shall be paid by Schering. Any overpayments by Schering will be
         credited against future royalty obligations. In the event that
         Schering disagrees with the audit report and the chief financial
         officers of Schering and Licensor (or their designees) fail to resolve
         such disagreement, the dispute will be resolved through the dispute
         resolution mechanism set forth in Section 9.2.

                  (c) Record Keeping by Sublicensee. Schering shall include in
         each sublicense granted by it pursuant to this Agreement a provision
         requiring the Sublicensee to make reports to Schering, to keep and
         maintain records of sales made pursuant to such sublicense and to grant
         access to such records by Licensor's independent accountant to the same
         extent required of Schering under this Agreement.

                  (d) Confidentiality. Licensor shall treat all financial
         information subject to review under this Section 3.7, or under any
         sublicense agreement, in accordance with the confidentiality provisions
         of this Agreement, and shall cause its accounting firm to enter into an
         acceptable confidentiality agreement with Schering obligating it to
         retain all such financial information in confidence pursuant to such
         confidentiality agreement.

                  (e) Binding Records. Upon the expiration of [ * ] months
         following the end of any Calendar Year, the calculation of royalties
         payable under this Agreement with respect to such year shall be binding
         and conclusive upon the Parties, and Schering, its Affiliates and its
         Sublicensees shall be released from any liability or accountability
         with respect to royalties for such Calendar Year.

         3.8 Income Tax Withholding. If at any time, any jurisdiction within the
Territory requires the withholding of income taxes or other taxes imposed upon
payments set forth in this Article III, Schering shall make such withholding
payments as required and subtract such withholding payments from the payments
set forth in this Article III, or if applicable, Licensor will promptly
reimburse Schering or its designee(s) of the amount of such payments, it being
understood that such withholding taxes are the obligation of Licensor. Schering
shall provide Licensor with documentation of such withholding and payment in a
manner that is satisfactory for purposes of the U.S. Internal Revenue


                                       21
<PAGE>   95

Service. Any withholdings paid when due hereunder shall be for the account of
Licensor and shall not be included in the calculation of Net Sales. Payments of
withholding taxes made by Schering pursuant to this Section 3.8 will be made
based upon financial information to be provided to Schering by Licensor and, to
the extent that such information is incorrect or incomplete, Licensor shall be
liable for any fine, assessment or penalty, or any deficiency, imposed by any
taxing authority in the Territory for any deficiency in the amount of any such
withholding or the failure to make such withholding payment. If Schering is
required to pay any such deficiency, or any such fine, assessment or penalty for
any such deficiency, Licensor shall promptly reimburse Schering for such
payments, which shall not be included in the calculation of Net Sales.

         3.9 Direct Affiliate Licenses. Whenever Schering shall reasonably
demonstrate to Licensor that, in order to facilitate direct royalty payments by
an Affiliate, it is desirable that a separate license agreement be entered into
between Licensor and such Affiliate, Licensor will grant such licenses directly
to such Affiliate by means of an agreement which shall be consistent with all of
the provisions hereof, provided that Schering guarantees the Affiliate's
obligations thereunder.

                                   ARTICLE IV
                                     PATENTS

         4.1 Filing, Prosecution and Maintenance of Patents. Licensor agrees to
diligently file, prosecute and maintain in the Territory, at Licensor's expense,
all Patent Rights owned in whole or in part by Licensor and licensed to Schering
under this Agreement, including without limitation, any Patent Rights covering
any Improvement(s). Schering shall determine the country(ies) in the Territory
with respect to which Schering desires Licensor to perform such activities and
will promptly notify Licensor to that effect. All such determinations shall be
made by Schering in accordance with its standard practices with respect to the
filing, prosecution and maintenance of patents, and Licensor's obligation to
file, prosecute and maintain each patent application or patent within the Patent
Rights under this Section 4.1 shall be limited to those countries selected by
Schering for such patent application or patent. Licensor shall supply Schering
with a copy of the applications as filed, together with notice of its filing
date and serial number. Licensor shall keep Schering regularly advised of the
status of pending patent applications (including, without limitation, the grant
of any Patent Rights), and upon the written request of Schering shall provide
copies of any substantive papers provided to or received from government patent
authorities related to the filing, prosecution and maintenance of such patent
filings. Schering shall treat all information, papers, and other materials
provided by Licensor pursuant to this Section 4.1 in accordance with the
confidentiality provisions of this Agreement.

         4.2 Option of Schering to Prosecute and Maintain Patents. Licensor
shall give [ * ] days prior written notice to Schering of any desire to cease
prosecution and/or maintenance of a particular Patent Right and, in such case,
shall permit Schering, at its sole discretion, to continue prosecution or
maintenance at its own expense. If Schering


                                       22
<PAGE>   96

elects to continue prosecution or maintenance, Licensor shall execute such
documents and perform such acts, at Schering's expense, as may be reasonably
necessary to effect an assignment of such Patent Rights to Schering. Any such
assignment shall be completed in a timely manner to allow Schering to continue
such prosecution or maintenance. Any patents or patent applications so assigned
shall not be considered Patent Rights.

         4.3      Enforcement.

                  (a) Notice and Discontinuance of Infringement. In the event
         that either Schering or Licensor becomes aware of any third party
         infringement within the Territory of any Valid Claim, it will notify
         the other Party in writing to that effect. Any such notice shall
         include evidence to support an allegation of infringement by such third
         party. Licensor shall have a period of [ * ] months from the date of
         said notice to obtain a discontinuance of such infringement or bring
         suit against the third party infringer. Licensor shall bear all the
         expenses of any suit brought by it. Schering shall have the right,
         prior to commencement of the trial, suit or action brought by Licensor,
         to join any such suit or action, and in such event shall pay one-half
         of all costs of such suit or action. In the event that Schering has
         joined in the action and shared in the costs thereof as set forth
         above, no settlement, consent judgment or other voluntary final
         disposition of the suit may be entered into without the consent of
         Schering. In the event that Schering has not joined the suit or action,
         Schering will reasonably cooperate with Licensor in any such suit or
         action and shall have the right to consult with Licensor and be
         represented by its own counsel, provided that Licensor shall
         periodically reimburse Schering for its out-of-pocket costs (excluding
         the costs of retaining its own outside counsel) incurred in cooperating
         with Licensor. Any recovery or damages derived from any suit under this
         Section 4.3(a) where Schering has joined and shared costs shall be used
         first to reimburse each of Licensor and Schering for its documented
         out-of-pocket legal expenses relating to the suit, shall be used second
         to reimburse Licensor for royalties lost as a result of reduced sales
         of Licensed Product, shall be used third to reimburse Schering for
         amounts attributed to Schering's lost profits, with any remaining
         amounts, including but not limited to punitive, exemplary, or other
         enhanced damages, to be shared [ * ] by the Parties. Any recovery or
         damages derived from a suit which Schering has not joined shall be
         retained by Licensor.

                  (b) Continuance of Infringement. If Licensor has neither
         obtained a discontinuance of such infringement nor brought suit against
         such infringer after the expiration of the [ * ] period specified in
         Subsection 4.3(a), Schering shall have the right, but not the
         obligation, to bring suit against such infringer under the Patent
         Rights and join Licensor as a party plaintiff, provided that Schering
         shall bear all the expenses of such suit. Licensor shall cooperate with
         Schering in any such suit for infringement of a Patent Right brought by
         Schering against a third party, and shall have the right to consult
         with Schering and to participate in and be represented by independent
         counsel in such litigation at its own expense.


                                       23
<PAGE>   97

         Schering shall periodically reimburse Licensor for its out of pocket
         costs (excluding Licensor's costs of retaining independent counsel)
         incurred in cooperating with Schering. Schering shall incur no
         liability to Licensor as a consequence of such litigation or any
         unfavorable decision resulting therefrom, including any decision
         holding any of the Patent Rights invalid or unenforceable, except that
         Schering shall indemnify and hold Licensor harmless for any monetary
         judgment or award against or penalty levied upon either Licensor or
         Schering arising out of Schering's acts in the enforcement of such
         Patent Rights. In the event that Schering recovers any sums through
         litigation under this Section 4.3(b) by way of damages or in settlement
         thereof, Schering shall retain all such sums.

         4.4      Third Party Infringement Suit.

                  (a) Defense. In the event that a third party sues Schering
         alleging that Schering's, its Affiliates' or its Sublicensees' making,
         having made, importing, exporting, using, distributing, marketing,
         promoting, offering for sale or selling Licensed Compound and/or
         Licensed Product in one or more countries in the Territory infringes or
         will infringe said third party's patent, then Schering may elect to
         defend such suit at its sole expense and discretion. To the extent that
         the alleged infringement is based upon the use of Licensed Compound,
         another compound from the Compound Library or the Licensor Know-How,
         Schering shall have no obligation to pay royalties to Licensor under
         Section 3.3 with respect to sales of Licensed Product in such
         country(ies) during the pendency of any such suit. Upon Schering's
         request and in connection with Schering's defense of any such third
         party infringement suit, Licensor shall cooperate with Schering for
         such defense provided, that Schering shall promptly reimburse Licensor
         for reasonable out-of-pocket costs and expenses incurred by Licensor in
         providing such cooperation (excluding Licensor's costs of retaining
         independent counsel). Licensor shall invoice Schering for such costs
         and expenses, and shall provide documentation for the invoice. The
         invoice shall be payable to Licensor or its designee(s) [ * ] days
         after receipt by Schering of the invoice.

                  (b) Licensing. Schering shall have the right to negotiate with
         said third party for a suitable license or assignment of rights under
         the relevant patents. In the event that such negotiation results in a
         consummated agreement, then any lump sum payment and/or royalty
         payments to be made thereunder shall be paid by Schering and shall be
         offset against any royalties due Licensor in accordance with the terms
         of Article 3.4.

         4.5 Certification Under Drug Price Competition and Patent Restoration
Act. Licensor and Schering each shall immediately give written notice to the
other of any certification of which they become aware filed pursuant to 21
U.S.C. ss.355(b)(2)(A)(iv) and 355(j)(2)(A)(vii), or any amendment or successor
statute thereto, claiming that Patent Rights covering Licensed Compound and/or
Licensed Product(s) are invalid or that infringement will not arise from the
manufacture, use or sale of a product containing


                                       24
<PAGE>   98

Licensed Compound or otherwise equivalent to Licensed Product by a third party.
Notwithstanding any provision to the contrary, in the event that the Patent
Rights at issue are owned and/or controlled by Licensor and Licensor has failed
to bring an infringement action against such third party at least [ * ] business
days prior to expiration of the forty five (45) day period set forth in 21
U.S.C. ss.355(c)(3)(C) (or any amendment or successor statute thereto), Schering
shall have the right to bring such an infringement action, in its sole
discretion and at its own expense, in its own name and/or in the name of
Licensor. At Schering's request, Licensor shall, at its own expense, provide
Schering reasonable assistance to conduct such infringement action, including,
without limitation, causing the execution of such legal documents as Schering
may deem necessary for the prosecution of such action. Schering shall
periodically reimburse Licensor for its out-of-pocket costs (excluding any of
Licensor's costs of retaining independent counsel) incurred in assisting
Schering. Schering shall incur no liability to Licensor as a consequence of such
litigation or any unfavorable decision resulting therefrom, including any
decision holding any of the Patent Rights invalid or unenforceable, except that
Schering shall indemnify and hold Licensor harmless for any monetary judgment or
award against or penalty levied upon either Licensor or Schering arising out of
Schering's acts in the enforcement of such Patent Rights. In the event that
Schering recovers any sums in such litigation by way of damages or in settlement
thereof, Schering shall have the right to retain all such sums to offset its
costs, losses and expenses.

         4.6 Abandonment. Subject to Schering's rights pursuant to Section 4.2,
Licensor shall at the earliest known date give notice to Schering of the grant,
lapse, revocation, surrender, invalidation or abandonment of any Patent Rights
licensed to Schering for which Licensor is responsible for the filing,
prosecution and maintenance under this Agreement.

         4.7 Patent Term Restoration. The Parties hereto shall cooperate with
each other in obtaining patent term restoration or its equivalent in the
Territory where applicable to Patent Rights. In the event that elections with
respect to obtaining such patent term restoration are to be made, Schering shall
have the right to make the election and Licensor agrees to abide by such
election.

         4.8 Notices Regarding Patents. All notices, inquiries and
communications in connection with this Article IV shall be sent in the manner
set forth in Section 9.7 to the Parties at the addresses and facsimile numbers

         5.1      Confidentiality.

                  (a) Nondisclosure Obligation. Each of Licensor and Schering
         shall use only in accordance with this Agreement, and shall not
         disclose to any third party, any of the other Party's Proprietary
         Information received by it pursuant to this Agreement without the prior
         written consent of the other Party. The foregoing obligations shall
         survive the expiration or termination of this Agreement for a period of
         [ * ] years. These obligations shall not apply when and to the extent
         Proprietary Information:

                           (i) is known by the receiving Party at the time of
                  its receipt, and not through a prior disclosure by the
                  disclosing Party, as documented by business records;

                           (ii) is at the time of disclosure or thereafter
                  becomes published or otherwise part of the public domain
                  without breach of this Agreement by the receiving Party;

                           (iii) is subsequently disclosed to the receiving
                  Party by a third party that has the right to make such
                  disclosure;

                           (iv) is developed by the receiving Party
                  independently of Proprietary Information or other information
                  received from the disclosing Party and such independent
                  development can be documented by the receiving Party;

                           (v) is disclosed to any institutional review board of
                  any entity conducting clinical trials, or any governmental or
                  other regulatory agencies in order to obtain patents, to gain
                  approval to conduct clinical trials or to market Licensed
                  Compound and/or Licensed Product, but such disclosure may be
                  made only to the extent reasonably necessary to obtain such
                  patents or authorizations; or

                           (vi) is required by law, regulation, rule, act or
                  order of any governmental authority or agency to be disclosed
                  by a Party, provided that


                                       26
<PAGE>   100

                  notice is promptly delivered to the other Party in order to
                  provide an opportunity to seek a protective order or other
                  similar order with respect to such Proprietary Information and
                  thereafter the disclosing Party discloses to the requesting
                  entity only the minimum Proprietary Information required to be
                  disclosed in order to comply with the request, whether or not
                  a protective order or other similar order is obtained by the
                  other Party.


                  (b) Disclosure to Agents. Notwithstanding the provisions of
         Section 5.1(a), Schering shall have the right to disclose Licensor's
         Proprietary Information to its Sublicensees, agents, consultants,
         Affiliates or other third parties (collectively "Agents") in accordance
         with this Section 5.1(b). Such disclosure shall be limited only to
         those Agents directly involved in the research, development,
         manufacture, marketing or promotion of Licensed Compound or Licensed
         Product (or for such Agents to determine their interest in performing
         such activities) in accordance with this Agreement. Any such Agents
         must agree in writing to be bound by confidentiality and non-use
         obligations essentially the same as those contained in this Agreement.
         The term of confidentiality and non-use obligations for such Agents
         shall be no less than [ * ] years. Schering shall be jointly and
         severally liable for any disclosure of Licensor Proprietary Information
         by Agents.

                  (c) Disclosure to a Third Party. Licensor shall have the right
         to use and disclose any Licensor Know-How at its sole option and
         discretion for the limited purpose of filing, prosecuting, and
         supporting Patent Rights. Subject to the terms of Section 5.2, either
         Party may publish Licensor Know-How under the terms of Section 5.3
         below. Licensor shall not otherwise disclose, provide or transfer any
         Licensor Know-How to any third party without the prior written approval
         of Schering.

         5.2 Publicity. Except as provided in Section 5.1 and this Section 5.2,
a Party may not use the name of the other Party in any publicity, advertising or
in any other public way and, may not issue press releases or otherwise publicize
or disclose any information related to the existence of this Agreement, the
terms or conditions of this Agreement, or any information relating to the
subject matter hereof, without the prior written consent of the other Party. The
Parties shall agree upon an initial press release to announce the execution of
this Agreement, together with a corresponding Q&A outline for use in responding
to inquiries about the Agreement. Following such initial press release, Licensor
may use the specific information contained therein, or in any subsequent public
announcements or publications made by Schering or by mutual agreement of the
Parties, in Licensor's investor relations and public relations activities.
Licensor shall make no public announcement, either written, oral or in any
medium relating to the safety of Licensed Compound and/or Licensed Product,
except for statements in official correspondence with government patent
authorities in support of Patent Rights as provided for in Section 5.1(c) [ * ].

         5.4 Publication. Schering and Licensor each acknowledge the potential
benefit in publishing results of certain studies to obtain recognition within
the scientific community and to advance the state of scientific knowledge. Each
Party also recognizes the mutual interest in obtaining valid patent protection
and in protecting business interests and trade secret information. No
publication of Licensor Know-How or Patent Rights may be made without the prior
written consent of Licensor. The Parties agree that Schering, its Affiliates,
employees or consultants shall be free to make any publication which does not
disclose Licensor Know-How or Patent Rights. In the event that any proposed
publication (as defined below) discloses Licensor Know-How or Patent Rights, the
following procedure shall apply: Either Party, its Affiliates, employees or
consultants wishing to make a publication shall deliver to the other Party a
copy of the proposed written publication or an outline of an oral disclosure at
least [ * ] days prior to submission for publication or presentation. For
purposes of this Agreement, the term "publication" shall include, without
limitation, abstracts and manuscripts for publication, slides and texts of oral
or other public presentations, and texts of any transmission through any
electronic media, e.g. any computer access system such as the Internet,
including the World Wide Web. The reviewing Party shall have the right (i) to
propose modifications to the publication for patent reasons, trade secret
reasons or business reasons or (ii) to request delay of the publication or
presentation in order to protect patentable information. If the reviewing Party
requests a delay, the publishing Party shall delay submission or presentation
for a period of up to [ * ] months from the filing date of the first patent
application in the Territory covering the information contained in the proposed
publication or presentation. If the reviewing Party requests modifications to
the publication, the publishing Party may edit such publication to prevent
disclosure of trade secret or proprietary business information prior to
submission of the publication or presentation.

         efforts not to diminish the rights under the Patent Rights and Licensor
         Know-How granted to Schering hereunder, including without limitation,
         by not committing or permitting any actions or omissions which would
         cause the breach of any license or other agreements between itself and
         third parties which provide for licenses, assignments or other rights
         to any Patent Rights or Licensor Know-How, that it will provide

of or relating to any preclinical and/or clinical studies involving the Licensed
Compound and/or Licensed Product conducted by or on behalf of Licensor (the

                   INDEMNIFICATION AND LIMITATION ON LIABILITY

         7.1 Indemnification by Schering. Schering shall indemnify, defend and
hold harmless Licensor and its Affiliates, and each of its and their respective
employees,


                                       32
<PAGE>   106

officers, directors and agents (each, a "Licensor Indemnified Party") from and
against any and all third party claims, demands, lawsuits, proceedings,
settlement amounts, liability, loss, damage, cost, and expense (including
reasonable attorneys' fees), (collectively, a "Liability") which may be asserted
against the Licensor Indemnified Party or which the Licensor Indemnified Party
may incur, suffer or be required to pay resulting from or arising out of (i) the
discovery, development, manufacture, promotion, distribution, use, testing,
marketing, sale or other disposition of Licensed Compound and/or Licensed
Product(s) by Schering, its Affiliates or Sublicensees (including without
limitation any personal injury, death, or other injuries suffered by users of
Licensed Compound or Licensed Product), or (ii) the breach by Schering of any
covenant, representation or warranty contained in this Agreement; or (iii) the
successful enforcement by a Licensor Indemnified Party of its rights under this
Section 7.1. Notwithstanding the foregoing, Schering shall have no obligation
under this Agreement to indemnify, defend or hold harmless any Licensor
Indemnified Party with respect to any Liability which results from the willful
misconduct or negligent acts or omissions of Licensor, its Affiliates, or any of
their respective employees, officers, directors or agents.

         7.2 Indemnification by Licensor. Licensor shall indemnify, defend and
hold harmless Schering and its Affiliates, and each of its and their respective
employees, officers, directors and agents (each, a "Schering Indemnified Party")
from and against any Liability which the Schering Indemnified Party may incur,
suffer or be required to pay resulting from or arising out of (i) the breach by
Licensor of any covenant, representation or warranty contained in this
Agreement; or (ii) the successful enforcement by a Schering Indemnified Party of
its rights under this Section 7.2. Notwithstanding the foregoing, Licensor shall
have no obligation under this Agreement to indemnify, defend or hold harmless
any Schering Indemnified Party with respect to any Liability which results from
willful misconduct or negligent acts or omissions of Schering, its Affiliates,
or any of their respective employees, officers, directors or agents.

         7.3 Conditions to Indemnification. Each Party agrees to promptly give
the other Party notice of any claim for which indemnification may be sought.
Failure of an indemnified Party to provide notice of a claim to the indemnifying
Party shall affect the indemnified Party's right to indemnification only to the
extent that such failure has a material adverse effect on the indemnifying
Party's ability to defend or the nature or the amount of the Liability. Subject
to the provisions of Article IV, the indemnifying Party shall have the right to
assume the defense of any suit or claim related to the Liability if it has
assumed responsibility for the suit or claim in writing; provided, however, that
if in the reasonable judgment of the indemnified Party, such suit or claim
involves an issue or matter which could have a materially adverse effect on the
business operations or assets of the indemnified Party, the indemnified Party
may waive its rights to indemnity under this Agreement and control the defense
or settlement thereof, but in no event shall any such waiver be construed as a
waiver of any indemnification rights such Party may have at law or in equity. If
the indemnifying Party defends the suit or claim, the indemnified Party may
participate in (but not control) the defense thereof at its sole cost and
expense.


                                       33
<PAGE>   107

         7.4 Settlements. Subject to the provisions of Article IV, neither Party
may settle a claim or action related to a Liability without the consent of the
other Party if such settlement would impose any monetary obligation on the other
Party or require the other Party to submit to an injunction or otherwise limit
the other Party's rights under this Agreement, provided that such consent shall
not be unreasonably withheld or delayed. Any payment made by a Party to settle
any such claim or action shall be at its own cost and expense.

         7.5 Limitation of Liability. With respect to any claim by one Party
against the other arising out of the performance or failure of performance of
the other Party under this Agreement, the Parties expressly agree that the
liability of such Party to the other Party for such breach shall be limited
under this Agreement or otherwise at law or equity to direct damages only and in
no event shall a Party be liable for, punitive, exemplary or consequential
damages suffered or incurred by the other Party.

         7.6 Insurance. Each Party acknowledges and agrees that during the Term
of this Agreement it shall maintain adequate insurance and/or a self-insurance
program for contractual liability insurance to cover such Party's obligations
under this Agreement. Each Party shall provide the other Party with evidence of
such insurance and/or self-insurance program, upon request.

                           (i) by either Party, subject to Section 9.2, if the
                  other Party is in breach of its material obligations with
                  respect to such product hereunder and has not cured such
                  breach within [ * ] days ([ * ] days with respect to payment
                  obligations under Article III) after written notice requesting
                  cure of the breach with reasonable detail of the particulars
                  of the alleged breach, or within [ * ] days of receiving
                  notice initiated actions reasonably expected to cure the cited
                  failure and thereafter diligently pursued such actions to cure
                  the failure (even if requiring longer than the [ * ] days set
                  forth in this subsection); or

                           (ii) by either Party upon the filing or institution
                  of bankruptcy, reorganization (in connection with any
                  insolvency), liquidation or receivership proceedings, or upon
                  an assignment of a substantial portion of the assets for the
                  benefit of creditors by the other Party, or in the event a


                                       35
<PAGE>   109

                  receiver or custodian is appointed for such other Party's
                  business, or if a substantial portion of such other Party's
                  business is subject to attachment or similar process;
                  provided, however, that in the case of any involuntary
                  bankruptcy proceeding such right to terminate shall only
                  become effective if the proceeding is not dismissed within
                  [ * ] days after the filing thereof.

                  (b)      Effect of Termination for Cause on License.

                           (i) Termination by Schering. In the event Schering
                  terminates this Agreement under Section 8.4(a)(i), due to a
                  breach by Licensor of its material obligations under Section
                  2.1(a), 2.1(b) or 2.11(a) of this Agreement, then Schering's
                  licenses pursuant to Sections 2.1 and 2.2 shall become fully
                  paid-up, perpetual licenses.

                           (ii) Termination by Licensor. In the event that
                  Licensor terminates this Agreement under Section 8.4(a)(i),
                  then the rights and licenses granted to Schering under
                  Sections 2.1 and 2.2 shall terminate and all rights to
                  Licensor Know-How, Licensed Compounds and Licensed Products
                  granted pursuant to this Agreement shall revert to Licensor.

                           (iii) Effect of Bankruptcy. In the event Schering
                  terminates this Agreement under Section 8.4(a)(ii) or this
                  Agreement is otherwise terminated under Section 8.4(a)(ii),
                  the Parties agree that Schering, as a licensee of rights to
                  intellectual property under this Agreement, shall retain and
                  may fully exercise all of its rights and elections under the
                  Insolvency Statute including as set forth in Section 9.8
                  hereof.

         8.5 Effect of Termination. Expiration or termination of the Agreement
shall not relieve the Parties of any obligation accruing prior to such
expiration or termination, and the provisions of Articles V and VII shall
survive the expiration of the Agreement. With regard to reimbursement for
development costs incurred by Licensor, including, without limitation, the costs
of clinical studies, Schering's obligations under Section 2.6 shall upon
termination be limited to the costs for actual work performed in accordance with
the relevant research plans or protocols up to the effective date of such
termination, or any irrevocable financial commitments made by Licensor prior to
the date of notice of termination. Any expiration or early termination of this
Agreement shall be without prejudice to the rights of either Party against the
other accrued or accruing under this Agreement prior to termination, including
the obligation to pay royalties for Licensed Product(s) or Licensed Compound
sold prior to such termination. In the event of termination of this Agreement,
Schering shall have the right to continue to sell its existing inventory of
Licensed Product during the [ * ] month period immediately following such
termination, provided that Schering shall continue to make royalty payments with
respect to such sales.

         8.6 Remedies for Breach. In addition to any and all other remedies that
Schering may have under this Agreement, or otherwise under law and/or equity, in
the event that Licensor materially breaches its obligations under Sections
6.6(a) or (b) of this Agreement and/or materially breaches its representation,
warranties and covenants under Section 6.2(m), then Schering shall have the
right, at Schering's sole discretion, upon written notice to Licensor to either:
(i) deduct [ * ] of the remaining unpaid milestone(s) in Section 3.2; (ii)
permanently reduce by [ * ] the royalty rates provided for in Section 3.3; or
(iii) immediately terminate the Agreement.

         8.7 Licensor's Rights on Termination. In the event that Licensor
terminates this Agreement under Section 8.3 or 8.4(a)(i), or Schering terminates
this Agreement under Section 8.2 or 8.3, Schering shall provide to Licensor the
following:

         (i)      all existing Regulatory Approvals and/or applications for
                  Regulatory Approval for the applicable Licensed Product(s) in
                  the Territory;

         (ii)     access, including the right to make copies, of all
                  preclinical, clinical, pharmacokinetic, toxicology or other
                  data owned or controlled by Schering which is necessary to
                  support any of the Regulatory Approvals provided to Licensor
                  under Section 8.7(i);

         (iii)    subject to the terms of Section 8.7 (iv), all preclinical and
                  clinical supplies of the applicable Licensed Product(s),
                  and/or Licensed Compound or other Compound Library compounds,
                  in Schering's possession or control;

         (iv)     access to all manufacturing information relating to the
                  Licensed Product, including assigning, sublicensing or
                  otherwise making available, as appropriate, any third party
                  manufacturing agreements relied upon by Schering for the
                  manufacture of Licensed Product, in each case to the extent
                  reasonably necessary for Licensor to manufacture the Licensed
                  Product following such termination;

         (v)      to the extent that termination occurs after the First
                  Commercial Sale of the applicable Licensed Product(s) and
                  subject to the terms of Section 8.5, Licensor shall have the
                  right to purchase Schering's remaining inventory of the
                  applicable Licensed Product(s) and/or Licensed Compound or
                  other Compound Library compounds for sale in the Territory at
                  [ * ] of Schering's fully absorbed manufacturing costs.

In addition, in the event of such termination, Schering shall grant to Licensor
a paid-up, non-exclusive, non-transferable license in the Territory under any
issued patents, or pending patent applications, owned or controlled by Schering
which would otherwise be infringed by the manufacture, use or sale of the
applicable Licensed Product(s) in the Territory, which license shall be
restricted to the sole purpose of making, having made, importing, exporting,
using, distributing, marketing, promoting, offering for sale


                                       37
<PAGE>   111

and selling such Licensed Product(s).

         8.8 Concurrent Termination with the International Agreement. In the
event of any termination of the International Agreement by either Licensor or
Schering-Plough Ltd. under the provisions of Sections 8.2, 8.3 or 8.4 of the
International Agreement, this Agreement shall automatically terminate
concurrently under the corresponding Section 8.2, 8.3 or 8.4 of this Agreement.


                                   ARTICLE IX
                                  MISCELLANEOUS

         9.1      Assignment/Change of Control.

                  (a) Assignment. Neither this Agreement nor any or all of the
         rights and obligations of a Party hereunder shall be assigned,
         delegated, sold, transferred, sublicensed (except as expressly
         permitted hereunder) or otherwise disposed of, by operation of law or
         otherwise, to any third party (other than an Affiliate of an assigning
         Party under the condition that the assignor remain responsible to the
         other Party under this Agreement), without the prior written consent of
         the other Party. Any attempted assignment, delegation, sale, transfer,
         sublicense or other disposition, by operation of law or otherwise, of
         this Agreement or of any rights or obligations hereunder contrary to
         this Section 9.1 shall be a material breach of this Agreement by the
         attempting Party, and shall be void and without force or effect;
         provided, however, either Party may, without such consent, assign the
         Agreement and its rights and obligations hereunder to an Affiliate or
         in connection with the transfer or sale of all or substantially all of
         its assets related to the division or the subject business, or in the
         event of its merger or consolidation or change in control or similar
         transaction. This Agreement shall be binding upon, and inure to the
         benefit of, each Party, its Affiliates, and its permitted successors
         and assigns. Each Party shall be responsible for the compliance by its
         Affiliates with the terms and conditions of this Agreement.

                  (b) Change of Control. In the event the ownership or control
         of Licensor is acquired by another pharmaceutical company that has an
         ongoing development program or commercializes (directly or through any
         Affiliate) any compound or product for the Primary Indication and/or
         the Secondary Indication, Licensor shall promptly notify Schering in
         writing to that effect. Licensor's obligations under Section 2.11 shall
         not extend to any such compound or product. Effective upon such notice,
         the JMC shall be disbanded and Schering will assume and thereafter be
         responsible for all of the rights and obligations of the JMC. Licensor,
         and following the change of control the acquiring party, shall use best
         efforts to ensure that such acquiring party does not have any access to
         any of Schering's Proprietary Information or other proprietary
         information relating to the development and commercialization of
         Licensed Product. Such best efforts shall


                                       38
<PAGE>   112

         include, without limitation: (i) ensuring that the acquiring party does
         not have access to any such information prior to the change of control
         of Licensor; and (ii) promptly destroying or returning to Schering all
         such information in Licensor's possession or control upon completion of
         the change of control. The acquiring party shall have no rights to use
         any Licensor Know-How relating to the Primary Indication or the
         Secondary Indication in connection with the development and
         commercialization of its own compound or product for the Primary and/or
         Secondary Indication. All of Schering's obligations under Article II to
         provide Licensor and/or the JMC with reports or to otherwise keep
         Licensor informed with respect to the development and commercialization
         of Licensed Compound, any other compound within the Compound Library
         and/or Licensed Product shall immediately terminate; provided, however,
         that Schering shall provide such acquiring party with an annual summary
         of its activities in developing and commercializing Licensed Product.

         9.2 Governing Law. This Agreement shall be governed, interpreted and
construed in accordance with the laws of the State of New Jersey, without giving
effect to conflict of law principles. All disputes under this Agreement shall be
governed by binding arbitration pursuant to the mechanism set forth in Schedule
9.2 attached hereto and incorporated hereby.

         9.3 Waiver. Any delay or failure in enforcing a Party's rights under
this Agreement or any waiver as to a particular default or other matter shall
not constitute a waiver of such Party's rights to the future enforcement of such
rights under this Agreement, nor operate to bar the exercise or enforcement
thereof at any time or times thereafter, excepting only as to an express written
and signed waiver as to a particular matter for a particular period of time.

         9.4 Independent Relationship. Nothing in this Agreement shall be deemed
to create an employment, agency, joint venture or partnership relationship
between the Parties hereto or any of their respective Affiliates, agents or
employees, or any other legal arrangement that would impose liability upon one
Party for the act or failure to act of the other Party. Neither Party shall have
any power to enter into any contracts or commitments or to incur any liabilities
in the name of, or on behalf of, the other Party, or to bind the other Party in
any respect whatsoever.

         9.5 Export Control. This Agreement is made subject to any restrictions
concerning the export of products or technical information from the United
States of America which may be imposed upon or related to Licensor or Schering
from time to time by the government of the United States of America.
Furthermore, Schering agrees that it will not export, directly or indirectly,
any technical information acquired from Licensor under this Agreement or any
products using such technical information to any country for which the United
States government or any agency thereof at the time of export requires an export
license or other governmental approval, without first obtaining the written
consent to do so from the Department of Commerce or other agency of the


                                       39
<PAGE>   113

United States government when required by an applicable statute or regulation.

         9.6 Entire Agreement; Amendment. This Agreement, including the Exhibits
and Schedules hereto and all the covenants, promises, agreements, warranties,
representations, conditions and understandings contained herein sets forth the
complete, final and exclusive agreement between the Parties with respect to the
subject matter hereof and supersedes and terminates all prior and
contemporaneous agreements and understandings between the Parties, whether oral
or in writing. There are no covenants, promises, agreements, warranties,
representations, conditions or understandings, either oral or written, between
the Parties other than as are set forth herein. No subsequent alteration,
amendment, change, waiver or addition to this Agreement shall be binding upon
the Parties unless reduced to writing and signed by an authorized officer of
each Party. Each Party in deciding to execute this Agreement has not relied on
any understanding, agreement, representation or promise by the other Party which
is not explicitly set forth herein.

         9.7 Notices. Except as provided under Section 4.8 hereof, any notice
required or permitted to be given or sent under this Agreement shall be hand
delivered or sent by express delivery service or certified or registered mail,
postage prepaid, or by facsimile transmission (with written confirmation copy by
registered first-class mail) to the Parties at the addresses and facsimile

9.8      Provisions for Insolvency.

                  (a) Effect on Licenses. All rights and licenses granted under
         or pursuant to this Agreement by Licensor to Schering are, for all
         purposes of Section 365(n) of Title 11 of the United States Code
         (together with its foreign equivalent, the "Insolvency Statute"),
         licenses of rights to "intellectual property" as defined in the
         Insolvency Statute. Licensor agrees that Schering, as licensee of such
         rights under this Agreement shall retain and may fully exercise all of
         its rights and elections under the Insolvency Statute provided that
         Schering makes all royalty payments under this Agreement. Licensor
         agrees during the Term of this Agreement to create and maintain current
         copies or, if not amenable to copying, detailed descriptions or other
         appropriate embodiments, to the extent feasible, of all such
         intellectual property. If a case is commenced by or against Licensor
         under the Insolvency Statute, Licensor (in any capacity, including
         debtor-in-possession) and its successors and assigns (including,
         without limitation, an Insolvency Statute trustee) shall,

                           (i)      as Schering may elect in a written request,
                  immediately upon such request:

                                    (A) perform all of the obligations provided
                           in this Agreement to be performed by Licensor
                           including, where applicable and without limitation,
                           providing to Schering portions of such intellectual
                           property (including embodiments thereof) held by
                           Licensor and such successors and assigns or otherwise
                           available to them; or

                                    (B) provide to Schering all such
                           intellectual property (including all embodiments
                           thereof) held by Licensor and such successors and
                           assigns or otherwise available to them; and

                           (ii) not interfere with the rights of Schering under
                  this Agreement, or any agreement supplemental hereto, to such
                  intellectual property (including such embodiments), including
                  any right to obtain such intellectual property (or such
                  embodiments) from another entity.

                  (b) Rights to Intellectual Property. If an Insolvency Statute
         case is commenced by or against Licensor, and this Agreement is
         rejected as provided in the Insolvency Statute, and Schering elects to
         retain its rights hereunder as provided in the Insolvency Statute, then
         Licensor (in any capacity, including debtor-in-possession) and its
         successors and assigns (including, without limitation, an Insolvency
         Statute trustee) shall provide to Schering all such intellectual
         property (including all embodiments thereof) held by Licensor and such
         successors and assigns, or otherwise available to them, immediately
         upon


                                       41
<PAGE>   115

         Schering's written request. Whenever Licensor or any of its successors
         or assigns provides to Schering any of the intellectual property
         licensed hereunder (or any embodiment thereof) pursuant to this Section
         9.8, Schering shall have the right to perform the obligations of
         Licensor hereunder with respect to such intellectual property, but
         neither such provision nor such performance by Schering shall release
         Licensor from any such obligation or liability for failing to perform
         it.

                  (c) Schering's Rights. All rights, powers and remedies of
         Schering provided herein are in addition to and not in substitution for
         any and all other rights, powers and remedies now or hereafter existing
         at law or in equity (including, without limitation, the Insolvency
         Statute) in the event of the commencement of an Insolvency Statute case
         by or against Licensor. Schering, in addition to the rights, power and
         remedies expressly provided herein, shall be entitled to exercise all
         other such rights and powers and resort to all other such remedies as
         may now or hereafter exist at law or in equity (including, without
         limitation, the Insolvency Statute) in such event. The Parties agree
         that they intend the foregoing Schering rights to extend to the maximum
         extent permitted by law, including, without limitation, for purposes of
         the Insolvency Statute:

                           (i) the right of access to any intellectual property
                  (including all embodiments thereof) of Licensor, or any third
                  party with whom Licensor contracts to perform an obligation of
                  Licensor under this Agreement, and, in the case of the third
                  party, which is necessary for the development, registration,
                  manufacture and marketing of Licensed Compound and/or Licensed
                  Product(s); and

                           (ii) the right to contract directly with any third
                  party described in (i) to complete the contracted work.

                  (d) Deemed Grant of Rights. In the event of any insolvency of
         Licensor and if any statute and/or regulation in any country in the
         Territory requires that there be a specific grant or specific clause(s)
         in order for Schering to obtain the rights and benefits as licensee
         under this Agreement which are analogous to those rights under Section
         365(n) of Title 11 of the United States Code, then this Agreement shall
         be deemed to include any and all such required grant(s), clause(s)
         and/or requirements.

                  (e) Security Interests. In addition to any other rights
         granted to Schering hereunder, with respect to any country in the
         Territory in which Schering reasonably determines that its rights set
         forth in this Section 9.8 are nonexistent or inadequate to protect
         Schering's interests in the licenses granted hereunder, Licensor shall,
         upon Schering's request, execute a security agreement, or any foreign
         equivalent, for each country in the Territory, granting Schering a
         secured interest in all intellectual property licensed to Schering
         under this Agreement.

         9.9 Force Majeure. Failure of any Party to perform its obligations
under this Agreement (except the obligation to make payments when properly due)
shall not subject such Party to any liability or place them in breach of any
term or condition of this Agreement to the other Party if such failure is due to
any cause beyond the reasonable control of such non-performing Party ("force
majeure"), unless conclusive evidence to the contrary is provided. Causes of
non-performance constituting force majeure shall include, without limitation,
acts of God, fire, explosion, flood, drought, war, riot, sabotage, embargo,
strikes or other labor trouble, failure in whole or in part of suppliers to
deliver on schedule materials, equipment or machinery, interruption of or delay
in transportation, a national health emergency or compliance with any order or
regulation of any government entity acting with color of right. The Party
affected shall promptly notify the other Party of the condition constituting
force majeure as defined herein and shall exert reasonable efforts to eliminate,
cure and overcome any such causes and to resume performance of its obligations
with all possible speed; provided, however, that nothing contained herein shall
require any Party to settle on terms unsatisfactory to such Party any strike,
lock-out or other labor difficulty, any investigation or proceeding by any
public authority, or any litigation by any third party. If a condition
constituting force majeure as defined herein exists for more than ninety (90)
consecutive days, the Parties shall meet to negotiate a mutually satisfactory
resolution to the problem, if practicable.

         9.10 Severability. If any provision of this Agreement is declared
illegal, invalid or unenforceable by a court having competent jurisdiction, it
is mutually agreed that this Agreement shall endure except for the part declared
invalid or unenforceable by order of such court; provided, however, that in the
event that the terms and conditions of this Agreement are materially altered,
the Parties will, in good faith, renegotiate the terms and conditions of this
Agreement to reasonably substitute such invalid or unenforceable provisions in
light of the intent of this Agreement.

         9.11 Counterparts. This Agreement shall become binding when any one or
more counterparts hereof, individually or taken together, shall bear the
signatures of each of the Parties hereto. This Agreement may be executed in any
number of counterparts, each of which shall be an original as against either
Party whose signature appears thereon, but all of which taken together shall
constitute but one and the same instrument.

         9.12 Captions. The captions of this Agreement are solely for the
convenience of reference and shall not affect its interpretation.

         9.13 Recording. Each Party shall have the right, at any time, to
record, register, or otherwise notify this Agreement in appropriate governmental
or regulatory offices anywhere in the world, and each Party shall provide
reasonable assistance to the other in effecting such recording, registering or
notifying. Notwithstanding the foregoing, prior to recording, registering, or
otherwise notifying this Agreement, the Party desiring to so record, register,
or notify shall provide a copy of all materials to be filed for review, comment,
and approval by the other Party, such approval not unreasonably to be withheld
or delayed.

         -        Active substances/ingredients

         -        Packaging components such as bottles, caps, labels, etc.

2.       Direct Labor

The cost of employees engaged in production activities that are directly
identifiable with product costs. Excludes supervision, which is included in
indirect labor, and production support activities such as inspection, plant and
equipment maintenance labor, and material handling personnel. Direct Labor cost
includes:

         -        Base pay, overtime, vacation and holidays, illness, personal
                  time with pay and shift differential.

         -        Cost of employee fringe benefits such as health and life
                  insurance, payroll taxes, welfare, pension and profit sharing.

3.       Indirect Manufacturing Costs

Costs which are ultimately allocated to product based on standard direct labor
hours of the operating departments. These costs include:

         -        Indirect Production Labor - salaries of employees engaged in
                  production activities who are not classified as direct labor,
                  including supervision, clerical, etc.

         -        Costs of Direct Labor - employees not utilized for the
                  manufacturing of product such as training, downtime and
                  general duties.

         -        Indirect Materials - supplies and chemicals which are used in
                  the manufacturing process and are not assigned to specific
                  products but are included in manufacturing overhead costs.
                  Includes supplies for which direct assignment to products is
                  not practical.

         -        Utilities - expenses incurred for fuel, electricity and water
                  in providing

                  property (manufacturing site, buildings and the fixed assets
                  of equipment, furniture and fixtures, etc.). If manufacturing
                  site includes other operations (marketing, R&D, etc.), taxes
                  are allocated to manufacturing on the basis of total real and
                  personal property.

         -        Cost of manufacturing, service departments - such as:
                  (where applicable)

4.       Quality Assurance Costs

Direct labor and indirect costs for Quality Assurance departments testing and
approving materials used in manufacturing and completed manufacturing batches
and finished products. This includes all manufacturing in-process testing and
testing of finished materials. Excluded from product costs are QA costs related
to research and development, stability testing, and other costs customarily
excluded from such Quality Assurance costs.

The following expenses are not included in manufacturing costs:
         a)       Inventory Carrying Costs

         b)       Regulatory Affairs Costs

         c)       Pilot plant costs, research batches and other similar costs
                  prior to turnover to manufacturing. These are handled as
                  development costs and expensed to R&D. This excludes
                  commercial goods produced by a research facility.

         d)       Costs incurred by Manufacturing for special projects (e.g.
                  requests by Schering-Plough Research Institute) to establish
                  and certify new production processes, batch sizes and product
                  line improvements, and new vendor certification of equipment
                  and primary materials components. These costs are expensed to
                  R&D.

         e)       Manufacturing start-up costs and initial one-time
                  extraordinary manufacturing costs incurred prior to plant
                  operation and achievement of a normal production activity
                  level. Includes costs of training, testing,
                  qualification/validation of new equipment and facilities and
                  initial, trial batches. These costs are deferred and then
                  amortized to Other Production Costs over five years.

         f)       Significant idle capacity is eliminated from factory overhead
                  and product cost. Idle or excess capacity costs are culled out
                  of the Manufacturing Budget and expensed as a period cost to
                  Other Production Costs.

         g)       Finished goods warehousing, shipping and other distribution
                  costs. These are included in distribution costs.

         h)       Product liability and/or business interruption insurance
                  expenses.

         i)       Intercompany profit.

5.       Other Production Costs

Three major types of expense are included in the Other Production Costs
classification.

         a)       Variances from standard cost the difference between the actual
                  and standard cost of inventory purchased and produced during
                  the period less any portion applicable to on-hand inventory
                  which has been capitalized.

                  (i)      Materials purchase price variance

                  (ii)     Materials usage/yield variances

                  (iii)    Direct labor efficiency/inefficiency - reflects the
                           cost difference between the standard and actual
                           number of direct labor


                                      iii
<PAGE>   122

                           hours used for actual production.

                  (iv)     Overhead - reflects all other labor and overhead cost
                           variances including activity and spending production
                           related and support.

                  With the exception of overhead, all of the other variances can
                  be identified by product and can be added (if unfavorable) or
                  subtracted (if favorable) to determine actual manufacturing
                  costs of a product.

         (b)      Non-standard costs: Cost of miscellaneous production related
                  operations for which standards are not established due to the
                  nature of the function, such as manufacturing start-up
                  operations, stock conversions and reclaiming (processing and
                  returning to finished goods inventory) of products returned by
                  customers. Also includes miscellaneous expenses incurred in
                  connection with the production of inventory which for various
                  reasons (e.g., cyclical, non-recurring) are not included in
                  standard costs. Examples include excess/idle capacity not
                  included in standards, abnormal waste or rework, experiments,
                  unallocated production costs, tooling and package design
                  costs.

                  Some of the above costs may be incurred for specific products,
                  e.g., rework, experiments, tooling, but the majority are
                  general to all products produced.

         (c)      Inventory adjustments: Consists of charges or credits due to
                  adjustments to inventory concerning revaluation to new
                  standards, stock conversions, capitalized/amortized production
                  variances, shortages or overages, and damage or obsolescence
                  of regular on-hand inventory or products returned by
                  customers.

Each of these charges or credits can be identified to a specific product.

                 ADVERSE EVENT REPORTING PROCEDURES FOR PRODUCTS


         The Parties understand and agree that these procedures are intended to
comply with 21 CFR 314.80(b) and 21 CFR 310.305(a) concerning standard written
procedures for adverse event reporting in the United States. These procedures
may be amended by the Parties at any time, at the request of either Party, to
ensure that they fully and accurately reflect the procedures in place for
surveillance, receipt, evaluation and reporting of adverse drug experiences by
the pharmacovigilance departments of the Parties and comply with applicable laws
and regulations in the countries in which the product(s) is marketed and/or is
under investigation. In that regard, upon the written request of either Party,
the Parties shall meet to renegotiate in good faith, all or some of these
procedures. Each Party may request such a meeting no more often than once in any
twelve (12) month period.


1.       Definitions:

         (a)      An Adverse Event ("AE") is defined as:

                           Sheet (CCDS).


                  ii)      Unexpected ("unlabeled") AE - An AE that does not
                           meet the criteria for an expected AE or an AE which
                           is listed but differs from that event in terms of
                           severity or specificity.

         (d)      IND Holder is defined as: A "Sponsor" as defined in 21 CFR
Part 312.2(b) of an investigational new drug in any regulatory jurisdiction,
including a holder of a foreign equivalent thereto.

         (e)      Life-threatening is defined as: any adverse drug experience
that places the patient, in the view of the initial reporter, at immediate risk
of death from the adverse drug experience as it occurred, i.e., it does not
include an AE that, had it occurred in more severe form, might have caused
death.

         (f)      NDA Holder is defined as: An "Applicant" as defined in 21 CFR
Part 314.3(b), for regulatory approval of a Licensed Product in any regulatory

         (g)      Serious or Non-Serious are defined as:

                  i)       Any adverse drug experience occurring at any dose
                           that results in any of the following outcomes: Death,
                           a life-threatening adverse drug experience, inpatient
                           hospitalization or prolongation of existing
                           hospitalization, a persistent or significant
                           disability/incapacity, or a congenital anomaly/birth
                           defect. Important medical events that may not result
                           in death, be life-threatening, or require
                           hospitalization may be considered serious when, based
                           upon appropriate medical judgment, they may
                           jeopardize the patient or subject and may require
                           medical or surgical intervention to prevent one of
                           the outcomes listed in this definition. Examples of
                           such medical events include allergic bronchospasm
                           requiring intensive treatment in an emergency room or
                           at home, blood dyscrasias or convulsions that do not
                           result in inpatient hospitalization, or the
                           development of drug dependency or drug abuse.
<PAGE>   128

                  ii)      A Non-serious AE is any AE which does not meet the
                           criteria for a serious AE.

         (h)      Not associated or unrelated to the use of the drug means it
does not meet the definition of "associated."

2.       Capitalized terms not defined in this Appendix shall have the meaning
assigned thereto in the Agreement.

3.       With respect to all Licensed Products:

                  All initial reports (oral or written) for any and all serious
                  AEs as defined above which become known to either Party (other
                  than from disclosure by or on behalf of the other Party) must
                  be communicated by telephone, telefax or electronically
                  directly to the other Party, NDA Holder, and/or IND Holder
                  (individually and collectively referred to as "Holders")
                  within five (5) calendar days of receipt of the information.
                  Written confirmation of the Serious AE received by the Party
                  should be sent to the other Party and the Holders as soon as
                  it becomes available, but in any event within two (2) business
                  days of initial report of the Serious AE by such Party.

                  All Parties and Holders should exchange Medwatch and/or CIOMS
                  forms and other health authority reports within two (2)
                  business days of submission to any regulatory agency.

                  All initial reports and follow-up information received for all
                  non-serious AEs for marketed Licensed Products which become
                  known to a Party (other than from disclosure by or on behalf
                  of the other Party) must be communicated in writing, by
                  telefax or electronically to the other Party and all Holders
                  on a monthly basis, on Medwatch or CIOMs forms (where
                  possible). All follow-up on any AE reports forwarded to either
                  Party by FDA must be submitted to FDA.

                  Each Party shall coordinate and cooperate with the other
                  whenever practicable to prepare a single written report
                  regarding all Serious AEs, provided, however, that neither
                  Party shall be obligated to delay reporting or any AE in
                  violation of applicable law or regulations regarding the
                  reporting of adverse events.

4.       The Parties further agree that:

         (a) a written report for AEs for animal studies which suggest a
potential significant risk for humans shall be forwarded to the other Party
within two (2) business days of receipt by the Party making the report,
<PAGE>   129

         (b) each Party will give the other Party a print-out or computer disk

days/calendar year, within thirty (30) days of receipt of a request from the
other Party;

         (c) upon request of a Party, the other Party shall make available its
AE records relating to Licensed Products (including computer disks) for viewing
and copying by the other Party,

         (d) disclosure of information hereunder by a Party to the other Party
shall continue as long as either Party continues to clinically test or market
product(s) containing Licensed Products or holds an open IND, NDA or foreign
equivalent thereto.

         (e) all written regulatory reports, including periodic NDA, annual IND,
safety updates, or foreign equivalents thereto, etc. should be sent by a Party
to the other Party within 2 business days of submission to the appropriate
regulatory agency. The Parties shall agree on a procedure for preparing these
reports (e.g. electronic mail, facsimile transmission, overnight service, etc.).

5.       Each Party shall diligently undertake the following further obligations
where both Parties are or will be commercializing products hereunder and/or
performing clinical trials with respect to Licensed Product:

         (a) to immediately consult with the other Party, with respect to the
investigation and handling of any serious AE disclosed to it by the other Party
or by a third Party, including government agencies, and to allow the other Party
to review the serious AE and to participate in the follow-up investigation;

         (b) to immediately advise the other Party of any Product safety
communication received from a health authority and consult with the other Party
with respect to any proposed change to product warnings, labeling or an
Investigator's Brochure involving safety issues, including, but not limited to,
safety issues agreed to by the Parties;

         (c) to diligently handle in a timely manner the investigation and
resolution of each AE reported to it; and

         (d) to provide the other Party reasonable annual audit rights of its AE
reporting system and documentation, upon prior notice, during normal business
hours, at the expense of the auditing Party and under customary confidentiality
obligations.

procedure with respect to adverse event reporting responsibilities, including
reporting responsibilities to investigators;

         (f) where possible, to transmit all data electronically;

         (g) to report to each other any addenda, revisions or changes to this
Agreement (e.g., change in territories, local regulations, addition of new
licensors/licensees to the agreement, etc.) which might alter the adverse event
reporting responsibilities hereunder;

         (h) to utilize English as the language of communication and data

         (c) Notice of Arbitration. A Party requesting arbitration hereunder
shall give a notice of arbitration to the other Party containing a concise
description of the matter submitted for arbitration, including references to the
relevant provisions of the Agreement and a proposed solution (a "Notice of
Arbitration"). Notice of Arbitration shall be delivered to the other Party in

         (e) Meeting. Within fifteen (15) days of receipt of the response from
the non-requesting Party pursuant to Paragraph (d), the Parties shall meet and
discuss in good faith options for resolving the dispute. The requesting Party

discovery, relating to depositions, document production and other discovery
devices, taking into account the nature of the dispute submitted for resolution.
If the Parties are unable to reach agreement as to the scope and schedule of
discovery, the Arbitrator may order such discovery as it deems necessary. To the
extent practicable taking into account the nature of the dispute submitted for
resolution, such discovery shall be completed within [*] days from the date of
the selection of the Arbitrator. At the hearing, which shall commence within [*]
days after completion of discovery unless the Arbitrator otherwise orders, the
Parties may present testimony (either live witness or deposition), subject to
cross-examination, and documentary evidence. To the extent practicable taking
into account the nature of the dispute submitted for resolution and the
availability of the Arbitrator, the hearing shall be conducted over a period not
to exceed [*] consecutive business days, with each Party entitled to
approximately half of the allotted time unless otherwise ordered by the
Arbitrator. Each Party shall have sole discretion with regard to the
admissibility of any evidence and all other matters relating to the conduct of
the hearing.

         (j) Witness Lists. At least [*] business days prior to the date
set for the hearing, each Party shall submit to the other Party and the
Arbitrator a list of all documents on which such Party intends to rely in any
oral or written presentation to the Arbitrator and a list of all witnesses, if

a brief summary of each witness' testimony. At least five (5) business days
prior to the hearing, each Party must submit to the Arbitrator and serve on each
other Party a proposed findings of fact and conclusions of law on each issue to
be resolved. Following the close of hearings, the Parties shall each submit such
post-hearing briefs to the Arbitrator addressing the evidence and issues to be
resolved as may be required or permitted by the Arbitrator.

         (k) Confidentiality. The arbitration proceedings shall be confidential
and, except as required by law, no Party shall make, or instruct the Arbitrator
to make, any public announcement with respect to the proceedings or decision of
the Arbitrator without the prior written consent of the other Party. The
existence of any dispute submitted to arbitration and the award of the
Arbitrator shall be kept in confidence by the Parties and the Arbitrator, except
as required in connection with the enforcement of such award or as otherwise
required by law.

         (l) Awards and Appeal. Subject to the provisions of this Schedule 9.2,
the decision of the Arbitrator shall be final and binding upon the Parties in
respect of all matters relating to the arbitration, the conduct of the Parties
during the proceedings, and the final determination of the issues in the
arbitration. There shall be no appeal from the final determination of the
Arbitrator to any court, except in the case of fraud or bad faith on the part of
the Arbitrator or any Party to the arbitration proceeding in connection with the
conduct of such proceedings. Judgment upon any award rendered by the Arbitrator
may be entered in any court having jurisdiction thereof.

         (m) Costs of Arbitration. The costs of any arbitration hereunder shall
be borne by the Parties in the manner specified by the Arbitrator in its
determination.

         (n) Performance of the Agreement. During the pendency of the
arbitration proceedings, the matter which is the subject of such arbitration
proceedings shall be performed by the Parties (A) in the manner determined by
Schering in its sole discretion if it is a matter relating to Schering's
development of Licensed Product, and (B) in the manner determined by Licensor in
its sole discretion if it is a matter involving payment of License Fees under
Section 3.1 and royalty payments under Sections 3.2 or 3.3. Notwithstanding the
foregoing, in the event that Schering makes payments pursuant to Sections 3.1,
3.2 or 3.3 and it is subsequently determined by the Arbitrator that Schering was
not required to make such payment(s) then Licensor shall promptly repay to
Schering all such payments. Further notwithstanding the foregoing, the time
periods set forth in Section 2.6(b) of the Agreement shall be suspended during
the pendency of the arbitration proceedings. For purposes of this Paragraph (n)
the term "pendency of the arbitration proceeding" shall mean the period starting
on the date on which arbitration proceedings are commenced by a Party in
accordance with Paragraph (c) of this Schedule 9.2 and ending on the date on
which the Arbitrator delivers its final determination in writing to the Parties.

                           EXCLUSIVE LICENSE AGREEMENT

         This License Agreement (the "Agreement") is made effective this 17th
day of July, 1998 (the "Effective Date") between THE REGENTS OF THE UNIVERSITY
OF CALIFORNIA, a California corporation having its statewide administrative
offices at 300 Lakeside Drive, 22nd Floor, Oakland, California 94612-3550, ("The
Regents") represented by the University of California, San Diego campus having
its offices at 9500 Gilman Drive, La Jolla, CA 92093-0910, and AtheroGenics
Inc. ("Licensee"), a Georgia corporation having offices at 3065 Northwoods
Circle, Norcross, GA 30071.

                                     WHEREAS

         1. Certain inventions, generally characterized as [*] and officially
recorded in[*] (collectively the "Invention"), were made in the course of
research at the University of California, San Diego by Dr. Joseph Witztum and
others and are covered by Regents' Patent Rights as defined herein;

         2. The development of the Invention was sponsored in part by the
National Institutes of Health and as a consequence this license is subject to
overriding obligations to the Federal Government under 35 U.S.C. 200-212 and
applicable regulations;

         3. Dr. Witztum and the other inventors are employees of The Regents.
The Regents have asked Dr. Witztum and his co-inventors to assign their rights
to The Regents;

         4. Licensee has evaluated the Invention under a Secrecy Agreement with
The Regents [*], and has communicated its evaluation to The Regents;

         5. Licensee and The Regents have executed a Letter of Intent dated June
27, 1997, that was amended on December 24, 1997 to extend the "Negotiation
Period," as defined therein, to March 1, 1998;

         6. Licensee wishes to obtain rights from The Regents for the commercial
development, use, and sale of products from the Invention, and The Regents is
willing to grant those rights so that the Invention may be developed to its
fullest and the benefits enjoyed by the general public; and

         7. Licensee is currently a "small business firm" as defined in 15
U.S.C. 632;

         8. The parties recognize and agree that royalties due under this
Agreement will be paid on both pending patent applications and issued patents;



                                       1
<PAGE>   5

         In view of the foregoing, the parties agree:

1.       DEFINITIONS

         1.1 "Regents' Patent Rights" means any subject matter claimed in or
covered by any of the following: Issued or Pending U.S. Patent Applications,
Provisional Applications and applications in preparation related to inventions
and as disclosed to Licensee as entitled [*] and assigned to The Regents; and
continuing applications thereof including divisions and substitutions but
excluding continuation-in-part applications (except continuations-in-part
applications supported by the original application); and patents issuing on said
applications including reissues, reexaminations and extensions; and any
corresponding foreign applications or patents.

         1.2 "Licensed Product" means any material that is either covered by
Regents' Patent Rights, that is produced by the Licensed Method, or that the use
of which would constitute, but for the license granted to Licensee under this
Agreement, an infringement of any pending or issued claim within Regents' Patent
Rights, including disease indications other than those set forth in the
Invention.

         1.3 "Licensed Method" means any method that is covered by Regents'
Patent Rights, the use of which would constitute, but for the license granted to
Licensee under this Agreement, an infringement of any pending or issued claim
within Regents' Patent Rights.

         1.4 "Net Sales" means the total of the gross invoice prices of Licensed
Products sold by Licensee, an affiliate, or a sublicensee, less the sum of the
following actual and customary deductions where applicable: cash, trade, or
quantity discounts; sales, use, tariff, import/export duties or other excise
taxes imposed on particular sales; transportation charges and allowances; or
credits to customers because of rejections or returns. For purposes of
calculating Net Sales, transfers to an affiliate or sublicensee for end use by
the affiliate or sublicensee will be treated as sales at list price.

         1.5 "Affiliate" means any corporation or other business entity in which
Licensee owns or controls, directly or indirectly, at least fifty percent (50%)
of the outstanding stock or other voting rights entitled to elect directors, or
in which Licensee is owned or controlled directly or indirectly by at least 50%
of the outstanding stock or other voting rights entitled to elect directors, but
in any country where the local law does not permit foreign equity participation
of at least 50%, then an "Affiliate" includes any company in which Licensee owns
or controls or is owned or controlled by, directly or indirectly, the maximum
percentage of outstanding stock or voting rights permitted by local law.

         1.6 "Field of Use" means all diagnostic and therapeutic use of the
Invention for human or veterinary application, including, but not limited to,
use in atherosclerosis and other cardiovascular and antiinflammatory diseases.

         1.7 "Know How" means all technical information and know-how, whether or
not patented, which is invented, developed, acquired and owned or licensed by
The Regents (other than from Licensee or its Affiliates or sublicensees) prior
to and during the term of this Agreement and which relate to the Invention;
excluding, however, any such item, information and data licensed by The Regents
with respect to which The Regents do not have a right to sublicense to third
parties.

2.       PERIOD OF PATENT EXCLUSIVE GRANT

         2.1 Subject to the limitations set forth in this Agreement, The Regents
grant to Licensee a world-wide license under Regents' Patent Rights and Know How
to make, have made, use, import and sell Licensed Products and to practice
Licensed Methods for the life of the longest-lived patent covering the Invention
described herein.

         2.2 Except as otherwise provided in this Agreement, the license granted
in Paragraph 2.1 is exclusive for the life of the Agreement.

         2.3 The license granted in Paragraphs 2.1 and 2.2 is subject to all the
applicable provisions of any license to the United States Government executed by
The Regents and is subject to the overriding obligations to the U.S. Government
under 35 U.S.C. 200-212 and applicable governmental implementing regulations.

         2.4 The licenses granted in Paragraphs 2.1 and 2.2 are limited to

Agreement for other methods and products not described in Regents Patent Rights,
and know-how pertaining to the Invention.

         2.5 The Regents reserves the right to use the Invention, know-how and
associated technology for educational and research purposes.

3.       SUBLICENSES

         3.1 The Regents also grant to Licensee the right to issue sublicenses
to third parties to make, have made, use, import and sell Licensed Products and
to practice Licensed Method, as long as Licensee has current exclusive rights
thereto under this Agreement. To the extent applicable, sublicenses must include
all of the rights of and obligations due to The Regents (and, if applicable, the
United States Government) and contained in this Agreement.

         3.2 Licensee shall promptly provide The Regents with a copy of each
sublicense issued; use diligent efforts to collect and guarantee payment of all

         3.3 Upon termination of this Agreement for any reason, The Regents, at
its sole discretion, shall determine whether Licensee shall cancel or assign to
The Regents any and all sublicenses.

         3.4 Licensee shall pay The Regents [*] of each non-royalty payment
received by Licensee from each sublicensee of the Licensed Products, unless the
Licensed Product contains (i) any know-how added by Licensee, in which case the
foregoing percentage for non-royalty payments shall be [*] or (ii) any antibody
or a material component in addition to know-how added by Licensee, in which case
the foregoing percentage for non-royalty payment shall be [*] or (iii) more than
one antibody or material component in addition to know-how added by Licensee, in
which case the foregoing percentage for non-royalty payments shall be [*]
(collectively, Licensed Products meeting the conditions of (i) (ii) or (iii) are
referred to hereafter as a "Value Added Licensed Product").

         3.5 Licensee shall pay The Regents [*] of each earned royalty payment
received by Licensee, unless the Licensed Product is determined to be a "Value
Added Licensed Product" as defined in this Section 3.4, in which case,
Licensee's royalty payment to The Regents shall be [*] of each royalty payment
received from each sublicensee. Licensee may at its sole discretion select the
alternative royalty payment schedule described in Section 7.5.

         3.6 In the event that circumstances relating to the sublicensing of the
Licensed Products arise that make the sublicensing of the Licensed Product
unfeasible or otherwise require consultations between the parties, the parties
agree to discuss these circumstances and negotiate in good faith any amendments
to this Agreement that may be mutually agreeable to the parties hereto.

4.       PAYMENT TERMS

         4.1 Paragraphs 1.1, 1.2, and 1.3 define Regents' Patent Rights,
Licensed Products and Licensed Methods so that royalties are payable on products
and methods covered by both pending patent applications and issued patents.
Royalties will accrue in each country for the duration of Regents' Rights in
that country and are payable to The Regents when Licensee receives payment from
a third party.

         4.2 Licensee shall pay earned royalties quarterly within ninety (90)
days after the end of the applicable quarter of each calendar year in which such
royalties are earned.

         4.3 All monies due The Regents are payable in United States dollars.
When Licensed Products are sold for monies other than United States dollars,
Licensee shall first determine the earned royalty in the currency of the country
in which Licensed Products were sold and then convert the amount into equivalent
United States funds, using the exchange rate quoted in the Wall Street Journal
on the date payment was received by the licensee.



                                       4
<PAGE>   8



         4.4 Royalties earned on sales occurring in any country outside the
United States may not be reduced by any taxes, fees, or other charges imposed by
the government of such country on the payment of royalty income. Licensee is
also responsible for all bank transfer charges. Notwithstanding this, all
payments made by Licensee in fulfillment of The Regents' tax liability in any
particular country will be credited against earned royalties or fees due The
Regents for that county.

         4.5 If at any time legal restrictions prevent the remittance of
royalties within 180 days by Licensee from any country where a Licensed Product
is, sold, Licensee shall convert the amount owed to The Regents into United
States funds and shall pay The Regents directly from its U.S. source of funds
for as long as the legal restrictions apply.

         4.6 If any patent or patent claim conferring exclusive marketing or
manufacturing rights to License under this Agreement within The Regents' Patent
Rights is held invalid in a decision by any court of competent jurisdiction, all
royalty payments will be held in an interest-bearing escrow account established
by the parties until a final decision is made by a court of competent
jurisdiction and last resort and from which no appeal has or can be taken, all
obligation to pay royalties based on that patent or claim or any claim patently
indistinct therefrom will cease as of the date of final decision. Licensee will
not, however, be relieved from paying any royalties that accrued and where
received before the final decision or that are based on another patent or claim
not involved in the final decision, or that are based on The Regents' property
rights.

         4.7 No royalties may be collected or paid on Licensed Products sold to
the account of the U.S. Government, any agency thereof, state or domestic
municipal government as provided for in the License to the Government.

         4.8 In the event payments, rebilling or fees are not received by The
Regents when due, Licensee shall pay to The Regents interest charges at a rate
of [*] per annum. Interest is calculated from the date payment was due until
actually received by The Regents.

5.       LICENSE-ISSUE FEE

         5.1 Licensee shall pay to The Regents a license-issue fee equal to the
higher of [*] of the patent costs reimbursable to The Regents under the Letter
of Intent, said license-issue fee to be paid on the first anniversary of the
execution of this License Agreement. Patent costs reimbursed to The Regents
within 30 days after the signing of this License Agreement shall not be used in
the license-issue fee calculation. This fee is [*].

milestone payments shall not be reimbursed to Licensee by The Regents.

7.       EARNED ROYALTIES AND MINIMUM ANNUAL ROYALTIES

         7.1 Unless provided to the contrary in Section 7.2 and 7.3, Licensee
shall pay to The Regents a royalty on worldwide Net Sales according to the
following schedule for therapeutic applications only:

[*] on sales of less than [*]
[*] on sales greater than [*], but less than [*]
[*] on sales greater than [*], but less than [*]
[*] on sales greater than [*], but less than [*]
[*] on sales greater than [*], but less than [*]

The Regents a royalty of on worldwide Net Sales according to the following
schedule for diagnostic applications only:

- - [*] on sales of Licensed Product in which the Licensed Method is supplemented
by monoclonal antibodies which are not included in The Regents Patent Rights;

Licensee;



                                       6
<PAGE>   10



- - [*] on all other sales of Licensed Product.

         7.2 If Licensee determines after consultation with The Regents that it
is required to pay royalties or other fees to any third party because the
manufacture, use, offer for sale, importation, or sale of a Licensed Method or a
Licensed Product would otherwise be likely to infringe any patent or other
intellectual property rights of such third party in a given country ("Third
Party Royalties"), Licensee may deduct from royalties thereafter due to The
Regents pursuant to this Agreement with respect to the Net Sales of such
Licensed Method or Licensed Product in such country up to [*] of the Third Party
Royalties. If the sum of the royalties paid hereunder and Third Party Royalties
for a given Licensed Product or a Licensed Method in a given country exceeds, at
any time, more than [*] on a therapeutic product or [*] on a diagnostic product
of the Net Sales, then upon Licensee's request, The Regents and Licensee agree
to negotiate in good faith in an effort to agree on a reduction in the royalties
payable hereunder to The Regents for such Licensed Product or Licensed Method in
such country. In the event the parties are unable to agree to such reduction
after a reasonable period of time, not to exceed thirty (30) days, either party
may request that the issue be arbitrated and the issue will be submitted to
final and binding arbitration in accordance with the rules of the American
Arbitration Association.

         7.3 Licensee may credit solely against all payments to The Regents,
including, without limitation, the royalties, accruing under this Agreement all
reasonable costs incurred by Licensee after the date hereof in connection with
any litigation, interference, opposition, or other action pertaining to the
validity, enforceability, allowability or subsistence of the Regents' Patent
Rights or whether Licensee's practice of the Regents' Patent Rights infringes a
third party patent.

         7.4 Licensee shall pay to The Regents a minimum annual royalty of [*]
for the life of Regents' Patent Rights, beginning with the year of the first
commercial sale of Licensed Product, but no later than the fifth-year
anniversary of the Effective Date. For the first year of commercial sales,
Licensee's obligation to pay the minimum annual royalty will be pro-rated for
the number of months remaining in that calendar year when commercial sales
commence and will be due the following March 31, to allow for crediting of the
pro-rated year's earned royalties. For subsequent years, the minimum annual
royalty will be paid to The Regents by March 31 of each year and will be
credited against the earned royalty due for the calendar year in which the
minimum payment was made.

         7.5 Licensee shall have the right to diligently sublicense the
Invention, the Licensed Products and the Licensed Method, including alternate
indications thereof, without restriction. In the case of a sublicense, Licensee
shall pay The Regents either of the following sublicense schedule as determined
by Licensee at its sole discretion:



                                       7
<PAGE>   11


         i) [*] of each payment received from the sublicensee for Licensed
Products that are not Value Added Licensed Products and [*] of each payment
received from the sublicensee for Value Added Licensed Products, or
         ii) Royalties on worldwide net sales in the amount set forth in
Sections 7.1.

In either schedule, payment shall be made to The Regents within ninety (90) days
of sublicense payment being received by Licensee, except as provided for in
Sections 3.1, 3.2 and 3.3.

8.       DUE DILIGENCE

with the development, manufacture and sale of Licensed Products and shall
earnestly and diligently endeavor to market the same within a reasonable time
after execution of this Agreement and in quantities sufficient to meet market
demands. The Regents expect that the first sale of Licensed Products shall occur
within twelve (12) years of the execution date of this Agreement, or within
eleven (11) years of the payment of the License Issue Fee, whichever is the
sooner, unless the first sale of Licensed Products is delayed by the process of
regulatory approval by federal, state or foreign national agencies.

         8.2 Licensee shall endeavor to obtain all necessary governmental
approvals for the manufacture, use and sale of Licensed Products, or shall
certify to The Regents in writing that none are needed.

         8.3 Licensee shall:

                  United States FDA within ten (10) years from the Effective
                  Date of this Agreement.

         8.3.2    market Licensed Products in the United States within one year
                  of receiving approval of the PLA for such Licensed Products

                  following commencement of marketing at any time during the
                  exclusive period of this Agreement.

         8.4 If the Licensee is unable to perform any of the above provisions,
then The Regents has the right and option to either terminate this Agreement or
reduce Licensee's exclusive license to a nonexclusive license. This right, if
exercised by The Regents, supersedes the rights granted in Article 2 (GRANT).



                                       8

         9.5 After the first commercial sale of a Licensed Product anywhere in
the world, Licensee shall make quarterly royalty reports to The Regents on or

10.      BOOKS AND RECORDS

         10.1 Licensee shall keep accurate books and records showing all
Licensed Products manufactured, used, and/or sold under the terms of this
Agreement. Books and records must be preserved for at least five (5) years from
the date of the royalty payment to which they pertain.

         10.2 Books and records must be open to inspection by representatives or
agents of The Regents at reasonable times. The Regents shall bear the fees and

total royalties due for any year is discovered in any examination then Licensee
shall bear the fees and expenses of that examination.

11.      LIFE OF THE AGREEMENT

         11.1 Unless otherwise terminated by operation of law or by acts of the
parties in accordance with the terms of this Agreement, this Agreement will be
in force from the Effective Date until the last-to-expire patent licensed under
this Agreement; or for twenty (20) years from the date of this Agreement if no
patent issues; or until the last patent application licensed under this
Agreement is abandoned and no patent in Regent's Patent Rights ever issues,
whichever occurs first. By mutual agreement, the Agreement can be extended until
the expiration date of the last-to-expire patent licensed under this Agreement;
or until the last patent application licensed under this Agreement is abandoned

days of the effective date of Notice of Default, The Regents may terminate this
Agreement and its licenses by a second written notice (Notice of Termination).

effective date of notice.

         13.2 Any termination under the above paragraph does not relieve
Licensee of any obligation or liability accrued under this Agreement prior to
termination or rescind any payment made to The Regents or anything done by
Licensee prior to the time termination becomes effective. Termination does not
affect in any manner any rights of The Regents arising under this Agreement
prior to termination.

14.      DISPOSITION OF LICENSED PRODUCTS ON HAND UPON TERMINATION

15.      USE OF NAMES AND TRADEMARKS

         Nothing contained in this Agreement confers any right use in
advertising, publicity, or other promotional activities any name, trade name,
trademark, or other designation of either party hereto (including contraction,

         16.4 Nothing in this agreement:

         16.4.1   is a warranty or representation by The Regents as to the
                  validity or scope of any Regents' Patent Rights;

         16.4.2   is a warranty or representation that anything made, used, sold
                  or otherwise disposed of under any license granted in this
                  Agreement is or will be free from infringement of patents of
                  third parties;

         16.4.3   is an obligation to bring or prosecute actions or suits
                  against third parties for patent infringement except as
                  provided in Article 19;

         16.4.4   confers by implication, estoppel or otherwise any license or
                  rights under any patents of The Regents other than Regents'
                  Patent Rights as defined in this Agreement, regardless of
                  whether those patents are dominant or subordinate to Regent's
                  Patent Rights; or

         16.4.5   is an obligation to furnish any know-how not provided in
                  Regents' Patent Rights.

17.      PATENT PROSECUTION AND MAINTENANCE

         17.1 As long as Licensee has paid patent costs as provided for in
Paragraph 17.5, The Regents shall diligently endeavor to prosecute and maintain
the United States and foreign patents comprising Regents' Patent Rights using
counsel of its choice selected from those approved by Licensee from the list
approved by The Regents. The Regents agrees to keep Licensee fully informed of
any and all patent prosecution and other actions with respect to Regents' Patent
Rights including sending to Licensee copies of all correspondence with patent
offices and local associates, submitting to Licensee copies of all draft
responses to Office Actions and other substantive filings in sufficient time
prior to filing to provide Licensee with adequate time to review and comment on
such matters; provided, however, that Licensee shall be responsible for any of
its expenses including attorney's fees that Licensee incurs in reviewing and
commenting on the information received from The Regents. The Regents shall
consult with Licensee regarding any material actions concerning the Patent
Rights and shall use all reasonable efforts to take such actions requested by
Licensee. If The Regents decide to abandon or allow to lapse any patent or
patent application within the Patent Rights in any country, The Regents will
inform Licensee in a timely manner and Licensee shall have the right to
prosecute or maintain any such patent or patent application at its expense. The
Regents shall provide Licensee with copies of all relevant documentation so that
Licensee may be informed of the continuing prosecution and Licensee agrees to
keep this documentation confidential. The Regents' counsel will take
instructions only from The Regents, or from Licensee after these instructions
have been approved by The Regents, and all patents and patent applications under
this Agreement will be assigned solely to The Regents.



                                       12
<PAGE>   16



         17.2 The Regents shall use all reasonable efforts to amend any patent
application to include claims reasonably requested by Licensee to protect the
products contemplated to be sold under this Agreement.

         17.3 Licensee shall apply for an extension of the term of any patent
related to the species of Fields of Use included within Regents' Patent Rights
if appropriate. Licensee shall prepare all documents, and The Regents agree to
execute the documents and to take additional action as Licensee reasonably
request in connection therewith.

         17.4 If either party receives notice pertaining to infringement or
potential infringement of any issued Licensed patents or plant-specific patent
included within Regents' Patent Rights, that party shall notify the other party
within ten (10) days after receipt of notice of infringement, and the terms of
Section 19 of this agreement shall apply.

         17.5 Licensee shall reimburse The Regents for all the costs of
preparing, filing, prosecuting and maintaining all United States and foreign
patent applications contemplated by this Agreement and requested by Licensee.
Relevant costs billed by The Regents' counsel will be rebilled to Licensee and
are due within 30 days of rebilling by The Regents. These costs include patent
prosecution costs for the Invention incurred by The Regents prior to the
execution of this Agreement and any patent prosecution costs that may be
incurred for patentability opinions, re-examination, re-issue, interferences, or
inventorship determinations. Prior costs relating to the filing of patents
requested by Licensee will be due on execution of this Agreement and billing by
The Regents.

         17.6 The Regents will notify Licensee of any actions with respect to
obtaining patents or other protection on the Invention as it relates to the
Field of Use in foreign countries. Licensee may request The Regents to obtain
patent or other patent protection on the Invention as it relates to the Field of
Use in foreign countries, if available. The Regents shall notify Licensee of any
action required to obtain or maintain foreign patents not less than ninety (90)
days prior to the deadline for any payment, filing, or action to be taken in
connection therewith. This notice concerning foreign filing must be in writing
and must identify the countries desired. The absence of a response by Licensee
to such a notice from The Regents to Licensee within forty five days of such
notice will be considered an election not to obtain or maintain foreign rights.

         17.7 Licensee's obligation to underwrite and to pay patent prosecution
costs will continue for so long as this Agreement remains in effect, but
Licensee may terminate its obligations with respect to any given patent
application or patent upon sixty (60) days written notice to The Regents. The
Regents will use its best efforts to curtail patent costs when a notice of
termination is received from Licensee. The Regents may prosecute and maintain
such application(s) or patent(s) at its sole discretion and expense, but
Licensee will have no further right or licenses thereunder. Non-payment of
patent costs may be deemed by The Regents as an election by Licensee not to
maintain application(s) or patent(s).

         17.8 The Regents may, after notification of Licensee, file, prosecute
or maintain patent applications at its own expense in any country in which
Licensee has not elected to have patent applications filed, prosecuted, or
maintained in accordance with this Article, and those applications and resultant
patents will not be subject to this Agreement.

18.      PATENT MARKING

         Licensee shall mark all Licensed Products made, used or sold under the
terms of this Agreement, or their containers, in accordance with the applicable
patent marking laws.

19.      PATENT INFRINGEMENT

         19.1 If Licensee learns of the substantial infringement of any patent
licensed under this Agreement, Licensee shall call The Regents' attention
thereto in writing and provide The Regents with reasonable evidence of
infringement. Neither party will notify a third party of the infringement of any
of Regents' Patent Rights without first obtaining consent of the other party,
which consent will not be unreasonably denied. Both parties shall use their best
efforts, including but not limited to arbitration, in cooperation with each
other to terminate infringement without litigation.

         19.2 Licensee may request that The Regents take legal action against
the infringement of Regents' Patent Rights. Request must be in writing and must
include reasonable evidence of infringement and damages to Licensee. If the
infringing activity has not abated within ninety (90) days following the
effective date of request, The Regents then has the right to:

         19.2.1   commence suit on its own account; or

         19.2.2   refuse to participate in the suit,

and The Regents shall give notice of its election in writing to Licensee by the
end of the one-hundredth (100th) day after receiving notice of written request
from Licensee. Licensee may thereafter bring suit for patent infringement, at
its own expense, if an only if The Regents elects not to commence suit and if
the infringement occurred during the period and in a jurisdiction where Licensee
had exclusive rights under this Agreement. If, however, Licensee elects to bring
suit in accordance with this paragraph, The Regents may thereafter join that
suit at its own expense.

         19.3 Legal action as is decided on will be at the expense or the party
bringing suit and all recoveries recovered thereby will belong to the party
bringing suit, but legal action brought jointly by The Regents and Licensee and
fully participated in by both will be at the joint expense of the parties and
all recoveries will be shared jointly by them in proportion to the share of
expense paid by each party.

         19.4 Each party shall cooperate with the other in litigation
proceedings instituted hereunder but at the expense of the party bringing suit.
Litigation will be controlled by the party bringing the suit, except that The
Regents may be represented by counsel of its choice and at its expense in any
suit brought by Licensee.

20.      INDEMNIFICATION

         20.1 Licensee shall indemnify, hold harmless and defend The Regents,
its officers, employees, and agents; the sponsors of the research that led to
the Invention; and the inventors of the parents and patent applications in
Regent's Patent Rights and their employers against any and all claims, suits
losses, damage, costs, fees, and expenses resulting from or arising out of
exercise of this license or any sublicense. This indemnification includes, but
is not limited to, any product liability.

         20.2 Licensee at its sole cost and expense, shall insure its activities
in connection with the work under this Agreement and obtain, keep in force and
maintain insurance as follows, or an equivalent program of self insurance:

(contractual liability included) with limits as follows:

         -        Each occurrence [*]
         -        Products/Completed Operations Aggregate [*]
         -        Personal and Advertising injury [*]
         -        General Aggregate (commercial form only) [*]

         The coverage and limits referred to under the above do not in any way
limit the liability of Licensee. Licensee shall furnish The Regents with
certificates of insurance showing compliance with all requirements. Certificates
must:

         -        Provide for thirty (30) day advance written notice to The
                  Regents of any modification.
         -        Indicate that The Regents has been endorsed as an additional
                  Insured under the coverage referred to under the above.
         -        Include a provision that the coverage will be primary and will
                  not participate with nor will be excess over any valid and
                  collectable insurance or program of self-insurance carried or
                  maintained by The Regents.

         20.3 The Regents shall notify Licensee in writing of any claim or suit
brought against The Regents in respect of which The Regents intends to invoke
the provisions of this Article. Licensee shall keep The Regents informed on a
current basis of its defense of any claims under this Article.

         3. PAYMENTS AND REPORTS

         3.1 ANNUAL FEE. As partial consideration for the rights conveyed by the
University under this Agreement, Licensee shall pay the University a minimum
annual license fee of [*] upon January 31 of each year that this Agreement is in
effect, beginning on January 31, 1998.

         3.2 LICENSED PRODUCTS ROYALTY. As partial consideration for the rights
conveyed by the University under this Agreement, Licensee shall pay the
University a running royalty of (i) [*] of Net Sales made in countries in which
a Licensed Product sold falls within the claims of a patent listed in Exhibit A,
and (ii) [*] of Net Sales made in countries if the Product is approved in the
country for the indication described in the patent claims. Such running
royalties shall be payable as provided in Paragraph 3.6. For the purposes of
this Section, a Licensed Product is considered to fall within the claims of the
patent if a dithiocarbamate which is included in a claim is sold for use in
combination with an antineoplastic or antibiotic agent that is included in the
claim.

         3.3 MILESTONE PAYMENTS. Licensee shall also pay the University the
following milestone payments: (a) [*] upon the submission of the first
Investigational New Drug Application for a Licensed Product to the FDA; and (b)
[*] upon the approval of the first New Drug Application for a Licensed Product
from the FDA.

         3.4 VALUE ADDED SUBLICENSING ROYALTY. In place of the royalty provision

sublicensed to a third party, Licensee agrees to pay to the University as
royalties hereunder, [*] of all Value Added Sublicensing Revenue arising from
sublicenses of the Subject Technology in countries in which the Subject
Technology is protected by patents owned by the University. If, however,
Licensee or Sublicensee is required to obtain third party rights to sell
Licensed Products which result in an actual reduction in the sublicense royalty
paid to Licensee, the [*] royalty to the University can be renegotiated to
reflect the required extra payments. If agreement cannot be reached on a
reasonable royalty under the circumstances, the parties agree to resolve the
dispute through arbitration conducted under the auspices of the American
Arbitration Association pursuant to the organization's rules for commercial
arbitration.

         3.5 STRAIGHT SUBLICENSING ROYALTY. In place of the royalty provision
set out in Section 3.2, if the Subject Technology or any aspect of it is
sublicensed to a third party, Licensee agrees to pay to University as royalties
hereunder, [*] of all Straight Sublicensing Revenue arising from sublicenses of
the Subject Technology in countries in which the Subject Technology is protected
by patents listed in Exhibit A. If, however, Licensee or Sublicensee is required

<PAGE>   4



party rights to sell Licensed Products which result in an actual reduction in
the sublicense royalty paid to Licensee, the [*] royalty to the University can
be renegotiated to reflect the required extra payments. If agreement cannot be
reached on a reasonable royalty under the circumstances, the parties agree to
resolve the dispute through arbitration conducted under the auspices of the
American Arbitration Association pursuant to the organization's rules for
commercial arbitration.

         3.6 QUARTERLY PAYMENTS. Payment of the royalties specified in Paragraph
3.2 shall be made by Licensee to the University within forty-five (45) days
after March 31, June 30, September 30 and December 31 of each year during the
term of this Agreement covering the quantity of Licensed Products sold by
Licensee during the preceding calendar quarter. Payment of the royalties
specified in Paragraphs 3.4 and 3.5 shall be made by Licensee to the University
within forty-five (45) days after receipt of payment from the sublicensee. After
termination or expiration of this Agreement, a final payment shall be made by
Licensee covering the whole or partial calendar quarter. Each quarterly payment
shall be accompanied by a written statement of Net Sales of Licensed Products by
Licensee during such calendar quarter. Such written statements shall be duly
signed by an authorized signatory of Licensee on behalf of Licensee and shall
show the Net Sales of Licensed Products by Licensee during such calendar quarter
and the amount of royalties payable under this Agreement based thereon.

         3.7 PAYMENTS IN DOLLARS. All payments due hereunder are expressed in
and shall be paid by check payable in United States of America currency, without
deduction of exchange, collection or other charges, to the University, or to the
account of the University at such other bank as the University may from time to
time designate by notice to Licensee. All currency conversion rates will be
calculated at the reported conversion rate in The Wall Street Journal on the
first day of the month in which the payment is due.

         3.8 INTEREST ON LATE PAYMENTS. In the event that any payment due
hereunder is not made when due, the payment shall accrue interest beginning on
the tenth day following the due date thereof, calculated at the annual rate of
[*], the interest being compounded on the last day of each calendar quarter,
provided, however, that in no event shall said annual interest rate exceed the
maximum legal interest rate. Each such royalty payment when made shall be
accompanied by all interest so accrued. Said interest and the payment and
acceptance thereof shall not negate or waive the right of the University to seek
any other remedy, legal or equitable, to which it may be entitled because of the
delinquency of any payment.

         4. RECORDS AND INSPECTION

         Licensee shall maintain or cause to be maintained a true and correct
set of records pertaining to the Net Sales of Licensed Products by Licensee
under this Agreement. During the term of this Agreement and for a period of one

         6. PATENTS AND INFRINGEMENT

         6.1 PATENT COSTS. After the Effective Date, Licensee agrees, with
respect to the Subject Technology, to pay all costs incurred by the University,
incident to the United States and foreign applications, patents and like
protection, including all costs incurred for filing, prosecution, issuance and
maintenance fees as well as any costs incurred in filing continuations,
continuations-in-part, divisionals or related applications and any reexamination
or reissue proceedings. Licensee shall have no obligation for any costs related
to the protection of the Subject Technology that were incurred prior to the
Effective Date.

         6.2 MAINTENANCE OF PATENTS. In the event that Licensee decides not to
continue any payments for prosecution of a patent application to issuance or
maintain any United States or foreign patent application or patent on the
Subject Technology, Licensee shall timely notify the University in writing in
order that the University may pay for such United States and said foreign




                                       5
<PAGE>   6



applications and continue said prosecution or maintenance of such patent
applications at its own expense, and the license rights as to such Subject
Technology covered by such patent application shall terminate with respect to
such country or countries as of the date of Licensee's notice.

         6.3 PATENT PROSECUTIONS. The University agrees to keep Licensee fully
informed of any and all patent prosecution and other actions with respect to the
Subject Technology including sending to Licensee copies of all correspondence
with patent offices and local associates, submitting to Licensee copies of all
draft responses to Office Actions and other substantive filings in sufficient
time prior to filing to provide Licensee with adequate time to review and
comment on, however, Licensee shall be responsible for any of its expenses
including attorney's fees that Licensee incurs in reviewing and commenting on
the information received from the University. The University shall consult with
Licensee regarding any material actions concerning the Patent Rights. The
University will use patent counsel acceptable to Licensee.

         6.4 COOPERATION. The University agrees to reasonably cooperate with
Licensee to whatever extent is reasonably necessary to procure and defend the
patent protection of any rights in the Subject Technology, including presenting
or amending any claims desired by Licensee, filing reissue or reexamination
applications or other documents desired by Licensee, and agreeing to execute any
and all documents to provide Licensee the full benefit of the licenses granted
herein.

         6.5 INFRINGEMENTS. Each Party shall promptly inform the other of any
suspected infringement of any claims in the Patent Rights or misuse,
misappropriation, theft or breach of confidence of other proprietary rights in
the Subject Technology by a third party, and with respect to such activities as
are suspected, Licensee shall have the right, but not the obligation, to
institute an action for infringement, misuse, misappropriation, theft or breach
of confidence of the proprietary rights against such third party. If Licensee
fails to bring such an action or proceeding within a period of three (3) months
after receiving notice or otherwise having knowledge of such infringement, then
the University shall have the right, but not the obligation, to prosecute at its
own expense any such claim. Should either the University or Licensee commence
suit under the provisions of this Paragraph 6.5 and thereafter elect to abandon
the same, it shall give at least thirty days written notice to the other Party
who may, if it so desires, continue prosecution of such action or proceeding.
All recoveries, whether by judgment, award, decree or settlement, from
infringement or misuse of Subject Technology shall be apportioned as follows:

to two times the cost and expenses incurred by such Party directly related to
the prosecution of such action or proceeding and the remainder shall be
distributed pursuant to the terms of this agreement.

         6.6 SETTLEMENTS. Neither the University nor Licensee shall settle any
action covered by Paragraph 6.5 without first obtaining the consent of the other
Party, which consent will not be unreasonably withheld.

         7. TERM AND TERMINATION

         7.1 TERM OF AGREEMENT. Unless earlier terminated as hereinafter
provided, this Agreement shall extend for the life of the last to expire patent
issued on the Subject Technology and shall then expire automatically. After such
expiration, Licensee shall have a perpetual, royalty-free license to make, use,
sell, offer to sell, and sublicense the Subject Technology.

         7.2 BREACH OF AGREEMENT. In the event of default or failure by either
Party to perform any of the terms, covenants or provisions of this Agreement,
such Party shall have thirty (30) days after the giving of written notice of
such default by the other Party to correct such default. If such default is not
corrected within the said thirty (30) day period, the other Party shall have the
right, at its option, to cancel and terminate this Agreement. The failure of the
other Party to exercise such right of termination for non-payment of royalties
or otherwise shall not be deemed to be a waiver of any right the other Party
might have, nor shall such failure preclude the other Party from exercising or
enforcing said right upon any subsequent default.

         7.3 BANKRUPTCY. The University shall have the right, at its option, to
cancel and terminate this Agreement in the event that Licensee shall (i) become
involved in insolvency, dissolution, bankruptcy or receivership proceedings
affecting the operation of its business or (ii) make an assignment of all or
substantially all of its assets for the benefit of creditors, or in the event
that (iii) a receiver or trustee is appointed for Licensee and Licensee, after
the expiration of thirty (30) days following any of the events enumerated above,
has been unable to secure a dismissal, stay or other suspension of such
proceedings.

         7.4 EFFECT OF TERMINATION. At the date of any termination of this
Agreement pursuant to Paragraph 7.2 hereof for breach by Licensee, or pursuant
to Paragraph 7.3 hereof, as of the receipt by Licensee of notice of such
termination, all rights to the Subject Technology shall revert to the University
and Licensee shall immediately cease using any of the Subject Technology and
return all copies of the same to the University; provided, however, that
Licensee may dispose of any Licensed Products actually in the possession of
Licensee or its agents prior to the date of termination, subject to Licensee's
paying to the University running royalties in accordance with Paragraph 3.2 with
respect thereto and otherwise complying with the terms of this Agreement.

         7.5 NO WAIVER. No termination of this Agreement shall constitute a
termination or a waiver of any rights of either Party against the other Party
accruing at or prior to the time of such termination. The University's waiver of
a single breach of any provision shall not be a waiver as to subsequent breaches
of the same provision.

              (d) Emory shall have the right to approve any sublicense
arrangement, which approval shall not be unreasonably withheld, which

<PAGE>   13

              (d) the amount of any consideration received by AtheroGenics from
sublicensees and an explanation of the contractual obligation satisfied by such
consideration; and

              (e) the occurrence of any event triggering a Milestone Payment

              Reports shall be made semiannually after the first Sale of a
Licensed Product. These royalty reports shall be due within ninety (90) days of
the close of every second and fourth AtheroGenics fiscal quarter. AtheroGenics
shall keep accurate records in sufficient detail to enable royalties and other
payments payable hereunder to be determined.

              6.2 Right to Audit. Emory shall have the right, upon prior notice
to AtheroGenics, not more than once in each AtheroGenics fiscal year, for the
period not exceeding the previous twenty four (24) months, through an
independent public accountant selected by Emory and acceptable to AtheroGenics,
which acceptance shall not be unreasonably refused, to have access during normal
business hours of AtheroGenics as may be reasonably necessary to verify the
accuracy of the royalty reports required to be furnished by AtheroGenics
pursuant to Section 6.1 of the Agreement. AtheroGenics shall include in any
sublicenses granted pursuant to this Agreement, a provision requiring the
sublicensee to keep and maintain records of Sales made pursuant to such
sublicense and to grant reasonable access to such records by Emory's independent
public accountant for the purpose of verifying the accuracy of royalty reports.
If such independent public accountant's report shows any underpayment of
royalties by AtheroGenics, its Affiliates or sublicensees, within ninety (90)
days after AtheroGenics' receipt of such report, AtheroGenics shall remit or
shall cause its sublicensees to remit to Emory:


                                       12

<PAGE>   14

              (a) the amount of such underpayment; and

              (b) if such underpayment exceeds [*] of the total royalties owed
for the fiscal year then being reviewed, the reasonably necessary fees and
expenses of such independent public accountant performing the audit. Otherwise,
Emory's accountant's fees and expenses shall be borne by Emory. Any overpayment
of royalties shall be fully refunded within ninety (90) days by Emory.

              6.3 Confidentiality of Records. All information subject to review
under this Article 6 shall be confidential. Except where provided by law, Emory
and its accountant shall retain all such information in confidence.

                               ARTICLE 7. PAYMENTS

              7.1 Payment Due Dates. Royalties and sublicense fees payable to
Emory as a result of activities occurring during the period covered by each
royalty report provided for under Article 6 of this Agreement shall be due and
payable on the date such royalty report is due. Payments of royalties in whole
or in part may be made in advance of such due date. Any payment in excess of [*]
shall be made by wire or transferred to an account of Emory designated by Emory
from time to time; provided, however, that in the event that Emory fails to
designate such account, AtheroGenics or its Affiliates and sublicensees may
remit payment to Emory to the address applicable for the receipt of notices
hereunder; providing, further, that any notice by Emory of such account or
change in such account, shall not be effective until fifteen (15) days after
receipt thereof by AtheroGenics.


                                       13

<PAGE>   15

               7.2 Currency Restrictions. Except as hereinafter provided in this
 Section 7.2, all royalties shall be paid in Dollars. If, at any time, legal
 restrictions prevent the prompt remittance of part of or all royalties with
 respect to any country in the Licensed Territory where Licensed Products are
 Sold, AtheroGenics or its sublicensee shall have the right and option to make
 such payments by depositing the amount thereof in local currency to Emory's
 account in a bank or depository in such country.

               7.3 Interest. Royalties and other payments required to be paid by
 AtheroGenics pursuant to this Agreement shall, if overdue, bear interest at the
 lesser of the maximum applicable legal rate of interest on overdue commercial
 accounts, or the LIBOR rate, calculated on an average daily basis over the
 period of the delinquency. The payment of such interest shall not foreclose
 Emory from exercising any other rights it may have because any payment is
 overdue.

                  ARTICLE 8. DEVELOPMENT AND MARKETING PROGRAM

              8.1 Diligence Obligations. AtheroGenics shall directly, or in
collaboration with Affiliates and sublicensees, use its best efforts:

              (a) to conduct a research and development program relating to the
use of Licensed Products in the Field; and

              (b) to promptly register Licensed Products with the FDA as
required by law.

              For purposes of this Agreement, "best efforts" shall mean that
AtheroGenics shall use reasonable efforts consistent with those used by
comparable biotechnology companies in the United States, at the same stage of
corporate and scientific development, in research and


                                       14

<PAGE>   16

development projects for diagnostic methods or kits and therapeutic methods or
compositions deemed to have commercial value comparable to the Licensed
Products.

              8.2 Fulfillment; Conversion. AtheroGenics' best efforts
obligations set forth in this Article 8 shall be deemed to have been fulfilled
if AtheroGenics (a) files an IND for Registration of a Licensed Product in the
United States within three (3) years after the effective date of this Agreement;
and (b) diligently pursues such Registration by complying with all FDA
requirements and appealing, to the extent permissible by law, any decisions
taken by the FDA which would prohibit Registration; and (c) commences marketing
at least one Licensed Product within six (6) months following Registration.

              If AtheroGenics fails to meet any deadline set forth in this
Section 8.2 or use best efforts as defined in Section 8.1 of this Agreement,
Emory may, upon at least ninety (90) days' prior written notice, convert this
license from an exclusive to non-exclusive license and grant third parties
rights in Licensed Patents and/or Licensed Technology equal to or lesser rights
than rights granted to AtheroGenics for the same Licensed Patents and/or
Licensed Technology, unless within such ninety (90) day period AtheroGenics
meets such deadline or demonstrates to the reasonable satisfaction of Emory that
it has resumed and will continue to use best efforts.

              8.3 Progress Reports. AtheroGenics shall, no less frequently than
once every twelve (12) months until a Licensed Product has been Registered,
provide Emory with a written report detailing AtheroGenics', its Affiliates' and
sublicensees, activities related to developing Licensed Products and pursuing
Registration of Licensed Products.


                                       15

<PAGE>   17

              8.4 Development Outside United States. No later than AtheroGenics'
filing of an NDA for a Licensed Product in the United States, AtheroGenics shall
directly, or in collaboration with Affiliates and sublicensees, use its best
efforts:

              (a) to obtain Registration for a Licensed Product in such other
countries of the Licensed Territory as AtheroGenics or AtheroGenics' Affiliates
and sublicensees deem appropriate; and

              (b) upon Registration of a Licensed Product in a particular
country proceed with due diligence to market such Licensed Product in such
country.

              8.5 Development of Indications.

              (a) AtheroGenics and Emory acknowledge that the compositions and
methods claimed in the Licensed Patents may be useful for a myriad of
indications. AtheroGenics shall, in accordance with its diligence obligations,
attempt to develop the Licensed Patents and Licensed Technology for all such
indications. However, because of the burdens, both financial and practical,
which may be accompanied by this requirement, such development is intended to be
staggered. Accordingly, AtheroGenics shall begin diligence requirements for its
second indication within [*] of the date of this Agreement, and thereafter for
one new indication at least once every [*]. Dates wherein diligence requirements
commence for a new indication shall be termed "Diligence Commencement Dates."

              (b) If AtheroGenics fails to begin using diligence to develop a
new potential indication an any Diligence Commencement Date in accordance with
Section 8.5 (a) of this Agreement, Emory may, commencing ninety (90) days after
that Diligence Commencement Date, request in writing that AtheroGenics enter
into good faith negotiations with prospective


                                       16

<PAGE>   18

 sublicensees which Emory believes are interested in developing an indication
 which AtheroGenics is not developing, for the purpose of sublicensing one new
 potential indication. Within sixty (60) days of receipt of such written
 request, AtheroGenics shall (i) commence and diligently pursue good faith
 negotiations with such prospective sublicensee or (ii) provide Emory with a
 detailed development plan, including milestones, for such indication in
 accordance with diligence requirements of this Agreement.


                         ARTICLE 9. PATENT PROSECUTION

              9.1 Licensed Patents Assigned Solely to Emory. AtheroGenics shall
be primarily responsible for all patent prosecution activities pertaining to
Licensed Patents assigned solely to Emory. AtheroGenics, with the agreement of
Emory, which agreement shall not be unreasonably withheld, shall select patent
counsel to prosecute all such Licensed Patents and shall provide Emory with
copies of all communications from patent offices, filings and correspondence
pertaining to such patent prosecution activities, in a timely manner, so as to
give Emory an opportunity to comment thereon prior to any responsive filing.
Emory shall have the right to have claims which are supported by the
specification added to an application.

              AtheroGenics shall pursue prosecution of such Licensed Patents in
at least the following countries: United States, EPO countries, Japan and
Canada. AtheroGenics shall, upon Emory's request, pursue prosecution of such
Licensed Patents in additional countries at Emory's expense.

              If AtheroGenics chooses not to timely file or pursue patent
protection or patent maintenance for any patent application or issued patent
assigned solely to Emory, AtheroGenics


                                       17

<PAGE>   19

shall notify Emory prior to abandonment in such a manner as would allow Emory a
reasonable period of time to take over prosecution or maintenance of said patent
application or issued patent. Such patent application or issued patent shall
then not be considered a Licensed Patent and Emory shall be free, at its
election, to abandon or maintain the prosecution of such patent application or
issued patent or grant rights to such patent application or issued patent to
third parties.

              9.2 Licensed Patents Jointly Assigned to AtheroGenics and Emory.
AtheroGenics shall be primarily responsible for all patent prosecution
activities pertaining to Licensed Patents assigned jointly to AtheroGenics and
Emory. AtheroGenics shall select patent counsel to prosecute all such Licensed
Patents and shall provide Emory with copies of all communications from patent
offices, filings and correspondence pertaining to such patent prosecution
activities, in a timely manner, so as to give Emory an opportunity to comment
thereon prior to any responsive filing. Emory shall have the right to have
claims which are supported by the specification added to an application.

              AtheroGenics shall pursue prosecution of such Licensed Patents in
at least the following countries: United States, EPO countries, Japan and
Canada. AtheroGenics shall, upon Emory's request, pursue prosecution of such
Licensed Patents in additional countries at Emory's expense.

              If AtheroGenics chooses not to timely file or pursue patent
protection or patent maintenance for any patent application or issued patent
assigned jointly to AtheroGenics and Emory, AtheroGenics shall, upon Emory's
request, assign its interests in such patent application or issued patent to
Emory. After such assignment, such patent application or issued patent shall
then not be considered a Licensed Patent and Emory shall be free, at its
election, to abandon or


                                       18

<PAGE>   20

maintain the prosecution of such patent application or issued patent or grant
rights to such patent application or issued patent to third parties.

                            ARTICLE 10. INFRINGEMENT

              10.1 If either AtheroGenics or Emory becomes aware of a product
made, used or sold in the Licensed Territory, which it believes infringes a
Valid Claim, the party obtaining such knowledge shall promptly advise the other
party of all relevant facts and circumstances pertaining to the potential
infringement. AtheroGenics shall have the right to enforce any issued Licensed
Patent against such infringement, at its own expense. Emory shall cooperate with
AtheroGenics in such effort, including being joined as a party to such action,
if necessary. During the pendency of such an action, royalty rates owed by
AtheroGenics to Emory shall be reduced by [*] from those listed in Article 5 of
this Agreement.

              10.2 Any damages or costs recovered by AtheroGenics in connection
with any action filed by AtheroGenics hereunder shall be applied first to
reimbursing AtheroGenics for costs and expenses of such litigation. Any damages
or costs recovered by AtheroGenics in excess of costs and expenses credited
shall be the sole property of AtheroGenics. Any such excess damages or costs
shall be treated as proceeds of Sales of Licensed Products in the fiscal quarter
received by AtheroGenics, and royalties shall be payable by AtheroGenics to
Emory thereon in accordance with the terms of this Agreement.

              10.3 Any multiplication of damages for punitive purposes shall be
treated as proceeds of Sales of Licensed Products in the fiscal quarter received
by AtheroGenics, and


                                       19

<PAGE>   21

royalties shall be payable by AtheroGenics to Emory thereon in accordance with
the terms of this Agreement, and AtheroGenics shall retain all attorney fees
awarded.

              10.4 If AtheroGenics shall fail, within one hundred twenty (120)
days after receiving notice from Emory of a potential infringement, or providing
Emory with notice of such infringement, to either (a) terminate such
infringement, (b) institute sub-licensing negotiations, to be completed within a
reasonable period of time, or (c) institute an action to prevent continuation
thereof and, thereafter to prosecute such action diligently, or if AtheroGenics
notifies Emory that it does not plan to terminate the infringement, negotiate a
sub-license or institute such action, then Emory shall have the right to do so
at its own expense. AtheroGenics shall cooperate with Emory in such effort,
including being joined as a party to such action if necessary. Emory shall be
entitled to retain all damages or costs awarded to Emory in such action.

                   ARTICLE 11. REPRESENTATIONS AND WARRANTIES

              11.1 Warranty of Ownership and Right to License. Emory represents

or its Affiliates or sublicensees, independent of disclosures from the other
party of this Agreement, provided that the persons developing such information
have not had any exposure to the information received from the disclosing party;

                           Shares as defined in the Stock Restriction Agreement.


                  ii.      The Stock is being acquired by you solely for your
                           account, for investment, with no present intention of
                           making a public distribution thereof within the
                           meaning of the Securities Act. None of the Stock will
                           be sold or transferred by you in violation of the
                           Securities Act or any state securities law, and your
                           financial condition is such that this investment can
                           be made on a long-term basis and you can afford the
                           complete loss of the investment. You are aware that
                           none of the Stock has been registered under the
                           Securities Act or any state securities law, that the
                           Stock must be held indefinitely unless they are
                           subsequently registered or an exception from such
                           registration is available and that the Company is
                           under no obligation to register any of the Stock
                           under the Securities Act or any state securities law.
                           You are aware that an exception from registration
                           requirements of the Securities Act pursuant to Rule
                           144 thereunder is not presently available; that the
                           Company has not covenanted to make available an
                           exception from the registration requirements pursuant
                           to such Rule 144 or any successor rule for resale of
                           any of the Stock; and that even if any exemption
                           under Rule 144 were available, the Rule permits only
                           routine sales of securities in limited amounts in
                           accordance with the terms and conditions of such
                           Rule. You further acknowledge that there is presently
                           no market for the purchase and sale of any of the
                           Stock.

                  iii.     You confirm that the Company has made available to
                           you, or to your representatives, the opportunity to
                           ask questions of its officers and directors and to
                           acquire such additional information about the
                           business and financial condition of the Company as
                           you request. You are not acquiring and will not
                           acquire the Stock based upon representations, oral or
                           written, by any person with respect to the future
                           value of, or income from, such Stock but rather upon
                           your independent examination and judgment as to the
                           prospects of the Company, You have all requisite

                           STOCK RESTRICTION AGREEMENT


                  THIS STOCK RESTRICTION AGREEMENT (this "Agreement") is made
and entered into as of April 26, 1995 by and between ATHEROGENICS, INC. a
Georgia corporation (the "Company"), and Sampath Parthasarathy, Ph.D., a
resident of Georgia ("Stockholder").

                                R E C I T A L S:

         A. Stockholder is being issued as of the date hereof forty thousand
(40,000) shares of the Common Stock of the Company (the "Shares") in connection
with that certain Patent Purchase Agreement of even date herewith (the "Patent
Purchase Agreement") and that certain Consulting Agreement dated of even date
herewith (the "Consulting Agreement"). As used herein, the term "Shares" refers
to all such shares presently held by the Stockholder and to all securities
purchased or otherwise received in addition thereto or in replacement thereof,
pursuant to or in consequence of any stock dividend, stock split,
recapitalization, merger, reorganization, exchange of shares or other similar
event.

         B. The Company is party to Series A Convertible Preferred Stock
Agreement (the "Purchase Agreement") dated as of May 6, 1994 with Alliance
Technology Ventures, L.P. ("Alliance") pursuant to which the Company issued to
Alliance the Company's Series A Convertible Preferred Stock. All capitalized
terms in this Agreement shall have the meanings ascribed to such terms in the
Purchase Agreement unless otherwise defined herein.

                  In order to provide assurance to Alliance and other persons
who may purchase or otherwise require shares of the Series A Convertible
Preferred Stock (the "Preferred Stock") of the Company in the future
(collectively, the "Investors") and thereby to assist in future equity
financings of the Company, Stockholder is willing to enter into this Agreement
for the benefit of the Company, the Investors and any other person or entity who
holds stock of the Company from time to time.

         THE PARTIES AGREE AS FOLLOWS:

         1. THE COMPANY'S RIGHT TO REPURCHASE UPON TERMINATION OF EMPLOYMENT.

                  1.1. REPURCHASE RIGHT. The unvested Shares, regardless of
ownership, shall be subject to a right (but not obligation) of repurchase in
favor of the Company (the "Right of Repurchase") at the price set forth below
("Purchase Price"), if the Stockholder's consultancy with the Company is
terminated by Stockholder other than for death or disability or by the Company
for cause which shall be the wilfull breach of the Consulting Agreement (the
"Consultancy Termination") before the Right of Repurchase expires with respect
to such Shares in accordance with Schedule 1.1. The Purchase Price shall be ten
cents (10(cent)) per Share for those

<PAGE>   15



40,000 Shares transferred in connection with the Patent Purchase Agreement and
the Consulting Agreement. The Stockholder may not dispose of or transfer or
pledge or grant a security interest in any Shares which are subject to the Right
of Repurchase and any such attempted transfer shall be null and void. The
Company's rights under this Section 1.1 shall be freely assignable, in whole or
in part.

                  1.2. REPURCHASE PROCEDURE. The Company's Right of Repurchase
shall terminate if not exercised by written notice from the Company to the
Stockholder within sixty (60) days from the date on which the Company learns of
the Consultancy Termination. If the Company exercises its Right of Repurchase,
the Stockholder shall promptly endorse and deliver to the Company the stock
certificates representing the Shares being repurchased free and clear of any
liens, claims or encumbrances, and the Company shall then pay promptly (but in
no event later than sixty (60) days after the date of Consultancy Termination,
or five (5) days after return of the stock certificate, whichever is later,
pursuant to the provisions of Section 1.3 of this Agreement, the total Purchase
Price to the Stockholder.

                  1.3. REPURCHASE PAYMENT. If, at the time of the repurchase,
any notes are outstanding which represent any portion of the total Purchase
Price for Shares being so repurchased, the Purchase Price shall be paid first by
cancellation of any obligation for accrued but unpaid interest under such notes,
next by cancellation of principal under such notes, and finally by payment of
cash or check.

                  1.4. BINDING EFFECT. The Company's Right of Repurchase shall
inure to the benefit of the successors and assigns of the Company and shall be
binding upon any representative, executor, administrator, heir, successor,
assignee or legatee of the Stockholder.

                  1.5. For purposes of this Article I and Article 2 below, if
Stockholder is also a member of the Board of Directors of the Company, the
Stockholder shall abstain from voting in regard to Company's Right of Repurchase
or Right of First Refusal (as that term is defined below).

         2. COMPANY'S RIGHT OF FIRST REFUSAL RESPECTING SHARES.

                  2.1. RIGHT OF FIRST REFUSAL. Without derogation of any
provisions of Section 1, and except as provided by Section 2.5 of this
Agreement, and if and to the extent Stockholder is allowed to sell under
applicable Securities laws which may restrict Stockholder's ability to sell,
pledge or otherwise transfer, in the event that the Stockholder proposes to
sell, pledge, or otherwise transfer any Shares or any interest in such Shares to
any person or entity, the Company shall have a right of first refusal (the
"Right of First Refusal") with respect to such Shares. Stockholder shall give a
written notice (the "Transfer Notice") to the Company describing fully any
proposed transfer of Shares, including the number of Shares proposed to be
transferred, the proposed transfer price, and the name and address of the
proposed transferee. The Transfer Notice shall be signed both by the Stockholder
and by the proposed transferee. The Company shall have the right to purchase
all, but not less than all, of the Shares subject to the Transfer

                                       2
<PAGE>   16



Notice at the same price and on the same terms as those indicated in the
Transfer Notice by delivery of a notice of exercise of the Company's Right of
First Refusal within thirty (30) days after the date the Transfer Notice is
delivered to the Company (the "Repurchase Period"). The Company's rights under
this Section 2.1 shall be freely assignable, in whole or in part. For purposes
of this Agreement, a transfer of Shares or any interest in Shares to an inter
vivos revocable trust which does not allow for the disposition of these Shares
except upon Stockholder's death and then only to Stockholder's immediate family
members, or transfer of Shares or any interest in Shares via a testimentary
instrument to Stockholder's immediate family members, shall not be considered a
transfer. However, subsequent sales, pledges or other transfers of any Shares or
interest in Shares shall be subject to this Right of First Refusal.
Notwithstanding anything to the contrary, any Shares so transferred shall be
subject to all limitations and restrictions of Section 1.1.

                  2.2. TRANSFER OF SHARES. If the Company fails to exercise the
Right of First Refusal within the Repurchase Period, the Stockholder, may, not
later than ninety (90) days following delivery to the Company of the Transfer
Notice, conclude a transfer of the Shares subject to the Transfer Notice on the
terms and conditions described in the Transfer Notice. Any proposed transfer on
terms and conditions different from those described in the Transfer Notice, as
well as any subsequent proposed transfer by the Stockholder, shall again be
subject to the Right of First Refusal and shall require compliance by the
Stockholder with the procedure described in Section 2.1 of this Agreement. If
the Company exercises the Right of First Refusal, the parties shall consummate
the sale of shares on the terms set forth in the Transfer Notice; provided,
however, in the event the Transfer Notice provides for payment for the Shares
other than in cash, the Company shall have the option of paying for the Shares
by the discounted cash equivalent of the consideration described in the Transfer
Notice.

                  2.3. BINDING EFFECT OF RIGHT OF FIRST REFUSAL. The Company's
Right of First Refusal shall inure to the benefit of the successors and assigns
of the Company and shall be binding upon any transferee of Shares other than a
transferee acquiring Shares in a bona fide arms-length transaction where the
Company failed to exercise the Right of First Refusal (a "Free Transferee"), or
a transferee of a Free Transferee.

                  2.4. TERMINATION OF THE COMPANY'S RIGHT OF FIRST REFUSAL.
Notwithstanding anything in this Section 2, the Company shall have no Right of
First Refusal, and Stockholder shall have no obligation to comply with the
procedures in Sections 2.1 through 2.3 after the earlier to occur of (i) the
Company's initial registered public offering of Common Stock to the public, or
(ii) the date ten (10) years after the date of this Agreement.

                  2.5. LIMITATIONS TO RIGHTS. Without regard and not subject to
the provisions of Sections 2.1 and 3.1, the Stockholder may sell or otherwise
assign for consideration Shares to any or all of his ancestors, descendants,
spouse, or members of his immediate family, or to a custodian, trustee
(including a trustee of a voting trust), executor, or other fiduciary for the
account of his ancestors, descendants, spouse, or members of his immediate
family, provided that each such transferee or assignee, prior to the completion
of the sale, transfer, or assignment, shall



                                       3
<PAGE>   17



have executed documents assuming the obligations of the Stockholder under this
Agreement with respect to the transferred securities.

         3. RIGHTS OF CO-SALE.

                  3.1. THE RIGHTS OF INVESTORS. Following the Repurchase Period,
if at any time Stockholder proposes to sell any Shares to parties other than the
Investors in a transaction (the "Transaction") not registered under the Act in
reliance upon a claimed exemption thereunder, then to the extent the Company has
not exercised its Right of First Refusal as to any Shares being sold, any
Investor which notifies the Company in writing, within thirty (30) days after
receipt of the notification from the Stockholder referred to in Section 3.2 (a
"Selling Holder") shall have the opportunity to sell a pro rata portion of
Shares which the Stockholder proposes to sell to such third party in the
Transaction; whereupon the Stockholder shall assign so much of his interest in
the agreement of sale as the Selling Holder shall be entitled to and shall
request hereunder, and the Selling Holder shall assume such part of the
obligations of the Stockholder under such agreement as shall relate to the sale
of the Shares by the Selling Holder. For the purposes of this Section 3, the
"pro rata portion" which the Selling Holder shall be entitled to sell shall be
an amount of shares equal to the total amount of Shares proposed to be sold
multiplied by a fraction, the numerator of which is the number of shares of
Common Stock issuable upon conversion of the Preferred Stock and shares of
Common Stock owned by a Selling Holder, and the denominator of which is the
total number of such shares owned by all participating Selling Holders and the
Stockholder. Each Selling Holder shall notify the Stockholder whether it elects
to sell an amount equal to or less than its pro rata portion of the Shares so
offered. Each Selling Holder shall be entitled to apportion Shares to be sold
among its partners and affiliates, provided that such Selling Holder notifies
the Company of such allocation.

                  3.2. NOTICE. Following the Repurchase Period, prior to any
sale by the Stockholder of any Shares, the Stockholder shall notify each
Investor and the Company, in writing, of his intention to sell and issue such
securities, setting forth the general terms under which he proposes to make such
sale. Such notice shall be signed by the third parties, or a representative of
such third parties, or shall be accompanied by a letter of intent signed by the
third parties or representatives of such third parties, to whom the sale,
assignment or transfer is proposed and shall indicate the third parties'
concurrence with the description of the terms.

                  3.3. FAILURE TO NOTIFY. If, within thirty (30) days after the
Stockholder gives his notice to the Investors, the Investors do not notify the
Company that they desire to sell all of their pro rata portion of the Shares
described in such notice at the price and on the terms and conditions set forth
therein, then the Stockholder may, not later than ninety (90) days following
delivery of the notice under Section 3.2 as to the Shares to which the Investors
do not indicate a desire to sell, conclude a transfer on the terms and
conditions described in the notice. In the event the Stockholder has not
concluded such sale of shares within such ninety (90) days, the Stockholder
shall not thereafter sell any Shares without first notifying the Investors and
the Company in the manner provided above. The exercise or non-exercise of the
right to participate in one or more sales of Shares made by the Stockholder
shall not adversely affect an Eligible




                                       4
<PAGE>   18




Holder's right to participate in subsequent sales of Shares by the Stockholder
pursuant to Section 3.1 hereof.

                  3.4. TERMINATION. The obligations of the Stockholder under
this Section 3 shall terminate and be of no further force and effect upon the
occurrence of either event described in subsection 2.4 of this Agreement.

         4. MARKET STANDOFF. The Stockholder hereby agrees that if so requested
by the Company or any representative of the underwriters in connection with any
registration of the offering of any securities of the Company under the Act, the
Stockholder shall not sell or otherwise transfer any Shares for a period of one
hundred eighty (180) days following the effective date of a Registration
Statement filed under the Act; provided, however, that such restriction shall
apply to the first two (2) Registration Statements of the Company to become
effective under the Act which include securities to be sold on behalf of the
Company to the public in an underwritten public offering under the Act. The
Company may impose stop-transfer instructions in order to enforce the foregoing
restrictions.

         5. TAXES. The Stockholder shall execute and deliver to the Company with
this executed Agreement a copy of the Acknowledgement and Statement of Decision
Regarding Election Pursuant to Section 83(b) of the Internal Revenue Code (the
"Acknowledgement") attached hereto as Schedule 5A. The Stockholder shall execute
and submit with the Acknowledgement a copy of the Election Pursuant to Section
83(b) of the Code, attached hereto as Schedule 5B, if the Stockholder has
indicated in the Acknowledgement his decision to make such an election. The
Stockholder should consult his tax advisor to determine if there is a comparable
election to file in the state of his residence and whether such filing is
desirable under the circumstances. The Company may withhold from the
Stockholder's wage, or require the Stockholder to pay to the Company, any
applicable withholding or employment taxes resulting from the lapse of any
restrictions imposed on the Shares.

         6. STOCK RESTRICTIVE LEGENDS. Stock certificates evidencing Shares may
bear such restrictive legends as the Company and the Company's counsel deem
necessary or advisable under applicable law or pursuant to this Agreement,
including, without limitation, the following legends:

                  "The securities represented hereby are subject to a right of
         first refusal by the Company and a right of co-sale on the part of
         certain stockholders pursuant to provisions of the Stock Restriction
         Agreement between the Company and Sampath Parthasarathy dated as of
         April 26, 1995, and may not be sold or otherwise transferred except in
         compliance with the terms of such agreement."

                             PATENT, COPYRIGHT AND
                            NONDISCLOSURE AGREEMENT



     In partial consideration and as a condition of my engagement as a
consultant by AtheroGenics, Inc., a Georgia corporation (the "Company"), and
effective as of the date that the consultancy by the Company first commenced,
the undersigned agrees as follows:

     1. NONCOMPETITION

     (a) The Company acknowledges and agrees that during the term of my
consultancy by, or any subsequent consultancy with the Company (the
"Consultancy Period"), I may continue to be employed by the Emory University
School of Medicine ("Emory") or may be employed by or consult with other
academic or non-profit research institutions. In the course of my employment or
consultancy with Emory or another medical school, I will perform services
traditionally performed by members of the faculty of such school, including,
without limitation, (i) teaching, (ii) providing medical services to patients
or related or affiliated hospitals or clinics, (iii) conducting research on
behalf of Emory with respect to medical devices, procedures and pharmaceuticals
or other compounds which may relate to or be used as prescription
pharmaceuticals (including pharmaceuticals which are or may be competitive with
those marketed, promoted or researched by the Company), (iv) researching and
testing pharmaceuticals or compounds manufactured or developed by third parties
under circumstances that result in compensation to Emory (and possible indirect
compensation to me) or such other school for such services, and (v) receiving
honoraria for presentations at medical conferences or seminars, except that I
will not investigate or develop for any other commercial entity (a) the
relationship of oxidation reactions to transcriptional factors, including NFxB,
in cardiovascular disease and other inflammatory diseases, (b) antioxidants and
their anti-inflammatory role in the activation of transcriptional factors in
cardiovascular disease and other inflammatory diseases, or (c) the commercial
development of antioxidants as potential therapeutic mediators in cardiovascular
diseases and other inflammatory diseases. Subject to the foregoing duties which
I perform or may perform for Emory or other academic or research institutions
during the Consultancy Period, I will not, without the prior written approval of
an executive officer of the Company (i) engage in any other professional
employment or consulting or (ii) directly or indirectly participate in or assist
in any business which is a current or potential competitor of the Company.

     (b) I understand and acknowledge that the Company is in the business of
researching, developing, marketing and worldwide promotion of prescription
pharmaceuticals, and that to assist in this business endeavor the Company will
be recruiting investors on a worldwide basis to furnish financial backing.
During the course of my consulting, I will be consulting in the foregoing areas,
i.e. researching, developing, investigating, producing, promoting, marketing
and sales of prescription pharmaceuticals, as well as recruiting investors. I
will acquire in-depth knowledge of certain of the Company's business practices
and confidential information.

<PAGE>   27





     (c) In light of the foregoing, during the Consultancy Period, I agree that
I will not directly or indirectly, expressly or tacitly, for myself or on
behalf of any entity anywhere in the world, (i) act as an officer, manager,
advisor, executive, controlling shareholder, or consultant to any business in
which my duties at or for such business include oversight of or actual
involvement in the research, development, investigation, production, promotion,
marketing or sales or prescription pharmaceuticals which are competitive with
those being produced or developed by the Company, or are under investigation by
the Company at the expiration of the Consultancy Period, (ii) recruit investors
on behalf of an entity which engages in researching, developing, investigating,
producing, promoting, marketing and sales of prescription pharmaceuticals which
are competitive with those being produced or developed by the Company, or are
under investigation by the Company at the expiration of the Consultancy Period,
or (iii) become employed by such an entity in any capacity which would require
me to carry out, in whole or in part, the duties I have performed for the
Company with respect to prescription pharmaceuticals which are competitive with
those being produced or developed by the Company, or are under active
investigation by the Company at the expiration of the Consultancy Period). I
acknowledge that because of the worldwide nature of the Company's business,
this restriction will prevent me from acting in any of the foregoing capacities
for any competing entity wherever located and that this worldwide scope is
reasonable in light of the business of the Company.

     (d) I further agree that during the Consultancy Period, and for a period
of two (2) years following the termination of the Consultancy Period, I will
not directly or indirectly, on my own behalf or in the service or on behalf of
others, solicit, suggest or direct others to solicit for hire any person
employed by the Company at the time of termination of the Consultancy Period.

     (e) I agree that during the Consultancy Period, and for a period of two (2)
years following the termination of the Consultancy Period, I will not, without
the prior written approval of an executive officer of the Company, on my own
behalf or in the service of or on behalf of others, knowingly solicit, divert,
or attempt to appropriate, to any business which competes with the Company in
the fields of research, development, investigation, production, promotion,
marketing, and sales of prescription pharmaceuticals, any person or entity who
is a customer of the Company or an actively sought prospective customer of the
Company (who is known as such by me) during my Consultancy Period.

     (f) I agree that the covenants contained in this Section 1 are reasonable
and necessary to protect the confidentiality of the trade secrets, and other
confidential information concerning the Company acquired by me. The provisions
of this Section 1 shall be interpreted so as to protect those trade secrets and
confidential information, and to secure for the Company the exclusive benefits
of the work performed on behalf of the Company by me under this Agreement, and
not to unreasonably limit my ability to engage in employment and consulting
activities in non-competitive areas which do not endanger the Company's
legitimate interests expressed in this Agreement.




                                       2
<PAGE>   28




     (g) In the event that any of the covenants contained herein in
subparagraphs (a) through (e) are deemed unenforceable by a court of competent
jurisdiction, I agree that each of the covenants herein is severable from each
of the others, and that a declaration of invalidity as to any one of the
covenants shall not effect the enforceability of the others. Further, in the
event one or more of the covenants herein is deemed unenforceable by a court of
competent jurisdiction, the parties hereby agree and request that the court
enforce the covenant(s) to the extent found reasonable by the court. I
acknowledge that I have had the assistance of counsel of my choice in
negotiation of this Agreement and of these covenants.

     2. INVENTIONS

        2.1 DISCLOSURE

            The Company acknowledges and agrees that pursuant to my employment
relationship with Emory or such other academic or non-profit research
institution or commercial enterprise as I may be engaged by in the future
("Employer"), Emory has, and an Employer may have, all right, title and
interest in and to any patentable or unpatentable, copyrightable or

improvement, method, process or discovery (any of the foregoing items
hereinafter referred to as an "Invention") arising out of, related to or based
upon my work for or on behalf of my Employer. Except for Inventions which arise
out of my employment and belong to my Employer, I will disclose promptly to the
proper officers of the Company in writing any Invention which relates to the
Company's business that I conceive, make, develop, or work on, in whole or in
part, solely or jointly with others during the term of my consultancy with the
Company and for a period of six months thereafter regardless of whether (a)
such invention was conceived, made, developed or worked on during my regular
hours of employment of my time away from work; (b) the Invention was made at
the suggestion of the Company; or (c) the Invention was reduced to drawing,
written description, documentation, models or other tangible form.

        2.2 ASSIGNMENT OF INVENTIONS TO COMPANY

            I hereby assign to the Company without royalty or any other further
consideration my entire right, title and interest in and to any Invention I am
required to disclose under Section 2.1.

        2.4 PATENTS

            Subject to Section 2.1, I will assist the Company in obtaining,
maintaining, and enforcing patents and other proprietary rights in connection
with any Invention covered by Section 2.2 for which the Company has or obtains
any right, title or interest. I farther agree that my obligations under this
Section 2.4 shall continue beyond the termination of the Consultancy Period, but
if I am called upon to render such assistance after the termination of the
Consultancy Period, I shall be entitled to a fair and reasonable rate of
compensation for such assistance. I shall, in addition, be entitled to
reimbursement of any out-of-pocket expenses incurred at the request of the
Company relating to such assistance.

        2.5 PRIOR CONTRACTS AND INVENTIONS: INFORMATION BELONGING TO THIRD
            PARTIES

            I represent that, except as set forth on Schedule 2.5A hereto an

inventions that are now in existence between any other person or entity and me.
I further represent that other than my employment obligations for Emory and the
NIH I have no other employments or undertakings which might restrict or impair
my performance of this Agreement I will not, in connection with my engagement
as a consultant by the Company, use or disclose to the Company any confidential
trade secret or other proprietary information or any previous employer or other
person to which I am not lawfully entitled. As a matter of record, I attach to
Schedule 2.5B of this Agreement a brief description of all Inventions made or
conceived by me prior to my engagement as a consultant with the Company which I
desire to be excluded from this Agreement.

     3. NONDISCLOSURE OF CONFIDENTIAL INFORMATION

     (a) I agree that all confidential information which is forwarded to me by
the Company and which is marked Confidential if forwarded in written form or
which is reduced to writing and marked Confidential within thirty days of
forwarding if forwarded in oral form shall be received in strict confidence,
used only for the purposes of this Agreement, and not disclosed by me (except as
required by law or court order) without the prior written consent of the other
Company, unless such information (a) was in the public domain at the time of
disclosure, (b) later became part of the public domain through no act or
omission of the by me, (c) was lawfully disclosed to me by a third party
having the right to disclose it, or (d) was already known by me at the time of
disclosure, as evidenced by written documents in my possession at the time of
the disclosure.

     (b) In order to fulfill my obligation of confidence hereunder, I shall use
at least the same degree of care with the Company's confidential information as
I use to protect my own confidential information. This obligation shall exist
while this Agreement is in force and for a period of four (4) years thereafter.

     All notes, memoranda, reports, drawings, blueprints, manuals, materials,
data and other papers and records of every kind which shall come into my

                                        3

<PAGE>   5



                  b.       A report of all activities undertaken and
                           accomplishments achieved through the Research Program
                           during the prior year (Principal Investigator).

         4.4      To facilitate the collaborative aspects of the Research
Program and to assist Sponsor's in-house research and development efforts,

the University in the course of the Research Program. In this regard, the
University agrees to provide Sponsor with research quantities of any tangible
technical material produced by the University in the course of the Research
Program and available in transferrable quantities upon written request of
Sponsor to do so. Any reasonable extra costs incurred by the University over and
above the costs set forth in Article III above in supplying such tangible
technical materials to Sponsor shall be paid by Sponsor on receipt of an
appropriate invoice from University.

                                  V. PUBLICITY

         No press release or any other written statements in connection with
work performed under this Agreement intended for use in the public media making
any reference to one party hereunder shall be made by the other party, except as
provided below. University, however, shall have the right to acknowledge
Sponsor's support of the investigations under this Agreement in scientific or
academic publications and other scientific or academic communications. In any
such statement, the parties shall describe the scope and nature of their
participation accurately and -appropriately. Any press release developed by
University regarding this Research Program will be submitted to Sponsor thirty
(30) days in advance of planned release, and Sponsor shall have the right to
review and comment upon such proposed press release to determine if
Sponsor-furnished Confidential Information or patentable information is included
therein. If so, the provisions regarding deferral of publications set forth in
Article VI below shall be applicable to such release.

                       VI. PUBLICATION AND ACADEMIC RIGHTS

         6.1      University and the Principal Investigator have the right to
publish or otherwise publicly disclose information gained in the course of this
Agreement. In order to avoid loss of patent rights as a result of premature
public disclosure of patentable information and to provide Sponsor an
opportunity to review proposed publication materials to determine whether such
material contains Sponsor-furnished Confidential Information (as defined in
Article VII), University will submit any prepublication materials to Sponsor for
review and comment at least thirty (30) days prior to planned submission for
publication.

         Sponsor shall notify University within this thirty (30) days period
whether Sponsor-furnished Confidential Information is contained therein and
whether it desires patent applications to be filed on any inventions contained
in the materials, in accord with the provisions of Attachment C. If requested by
Sponsor, University shall delay publication of any portion of the


                                       4

<PAGE>   6



materials for an additional period not to exceed ninety (90) days, unless a
further extension is mutually agreed upon, in order to facilitate filing of a
patent application in the United States. University shall have final authority
to determine the scope and content of any publications; however if any such
publication discloses Sponsor's Confidential Information (as defined in Article
VII), University agrees to delete such information prior to publication.

         6.2      It is understood that the University investigators may discuss
the research being performed under this Agreement with other investigators but
shall not reveal information which is Sponsor's Confidential Information under
Article VII hereof, nor shall a public disclosure of patentable information be
made except as set forth in Article V and in Paragraph 6.1 hereof. In the event
any joint inventions relating to the subject matter of the Research Program,
between the University investigators being funded by this Agreement and other
investigators, result from such discussions, University shall grant to Sponsor
the rights outlined in Attachment C to this Agreement, except that, in the event
there exist obligations, relating to the joint inventions, to another party as a
result of the involvement of the other investigators, University shall, in good
faith, exercise reasonable efforts to enable Sponsor to obtain full rights to
the joint invention.

                          VII. CONFIDENTIAL INFORMATION

         7.1      The parties may wish, from time to time, in connection with
work contemplated under this Agreement, to disclose Confidential Information to
each other. For the term of this Agreement and for a period of four (4) years
following termination of this Agreement, Sponsor and University each agrees that
it shall regard, maintain and preserve the secrecy and confidentiality of any
and all information and data, whether in oral or written form, including but not
limited to, products, processes, methods, concepts, ideas, programs, formulas,
apparatuses, chemicals, organisms, molecules, prototypes, techniques, know-how,
marketing plans, business plans, financial information, data, strategies,
forecasts, customer lists or technical requirements of customers, or other trade
secrets (collectively referred to herein as the "Proprietary Information") of
the other party which may be disclosed to or obtained by it pursuant to this
Agreement. Sponsor and University each agrees that it will not, at any time
without the prior written consent of the other party, use or disclose the
Proprietary Information belonging to the other party for any reason or in any
manner whatsoever except as may be necessary for the operation of this
Agreement, as explicitly authorized under this Agreement, or as required by law.

         7.2      Sponsor and University shall each take the same measures to
preserve the secrecy and confidentiality and avoid the unauthorized use or
disclosure of the other party's Proprietary Information as such party takes to
protect its own Proprietary Information.

         7.3      Sponsor and University shall each limit access to the
Proprietary Information to those of its employees and agents, Affiliates,
sublicensees, consultants, outside contractors, governmental regulatory
authorities and clinical investigators who have a reasonable need for access to
such information in connection with the operation of this Agreement. The
University


                                        5

<PAGE>   7


shall require all personnel assigned to the Research Program to comply with, and
to assist the University in complying with, the terms of the Agreement,
including maintaining the confidentiality of Sponsor's Confidential Information.
To this end the University shall require all personnel assigned to the Research
Program to individually sign a confidentiality agreement in the form attached as
Attachment D. Further, each party or its Affiliates or sublicensees may disclose
Proprietary Information to the United States government or other regulatory
authorities to the extent that such disclosure is necessary for the prosecution
and/or enforcement of patents or for authorizations to conduct clinical trials
or commercially market Licensed Products, provided that such party is otherwise
entitled to engage in such activities under this Agreement, or may disclose
Proprietary Information as is necessary to exercise any rights which survive
termination or expiration of this Agreement. All persons or entities to whom
Proprietary Information is disclosed shall be subject to the non-disclosure
covenants contained herein.

         7.4      Sponsor and University shall each use its best efforts to
disclose Proprietary Information to the other in writing and marked as
proprietary. If it is necessary to first disclose such information other than in
written form, the disclosing party shall, within thirty (30) days of such first
disclosure, reduce the information to writing and provide the receiving party
with a copy of such information marked as proprietary.

         7.5      Sponsor and University each acknowledges that the disclosure
of Proprietary Information under this Agreement confers no rights in the
receiving party other than the right to use the Proprietary Information of the
disclosing party for the operation of this Agreement. Upon termination of this
Agreement, or forthwith upon the request of the other party, Sponsor and
University shall promptly return to the other party all such documents,
drawings, samples, specimens or reproductions thereof which may have come into
its possession.

         7.6      The obligations undertaken by Sponsor and University hereunder
shall not apply to any portion of the Proprietary Information disclosed
hereunder which:

                  a.       was known to the non-disclosing party prior to
                           disclosure of such Proprietary Information by the
                           disclosing party; or

                  b.       is, or shall become, other than by an act or omission
                           of the non-disclosing party, generally available to
                           the public; or

                  c.       shall, by lawful means, be made available to the
                           non-disclosing party by a third party with the right
                           to disclose; or

                  d.       is required by law to be disclosed by the
                           non-disclosing party, provided the non-disclosing
                           party uses its best efforts to notify the disclosing
                           party immediately upon learning of such requirement
                           in order to give the disclosing party reasonable
                           opportunity to oppose such requirement; or


                                        6

<PAGE>   8



                  e.       results from research and development by the
                           receiving party or its Affiliates or sublicensees,
                           independent of disclosures from the other party of
                           this Agreement, provided that the persons developing
                           such information have not had any exposure to the
                           information received from the disclosing party; or

                  f.       Sponsor and University agree in writing may be
                           disclosed.

         7.7      In claiming the benefit of any of these exceptions, the
non-disclosing party shall have the burden of establishing that a portion of the
Proprietary Information is subject to such exception.

                VIII. PATENTS, COPYRIGHTS, AND TECHNOLOGY RIGHTS

         As partial consideration for payments made by Sponsor hereunder,
Sponsor and University agree to the terms concerning patents, copyrights, and
technology rights set forth in Attachment C.

                                  IX. LIABILITY

         9.1      Sponsor agrees to hold harmless the University, its officers,
agents and employees from any liability, loss or damage Sponsor may suffer as a
result of claims, demands, costs or judgments against Sponsor arising out of the
activities to be carried out pursuant to the obligations of this Agreement, and
the use by Sponsor of the results obtained from the activities performed by
University under this Agreement; provided, however, that any such liability,
loss or damage resulting from the following Sub-sections "a" or "b" is excluded
from this Agreement to hold harmless:

                  a.       the negligent or willful failure of University to
                           substantially comply with any applicable FDA or other
                           governmental requirement; or

                  b.       the negligence or willful malfeasance of any officer,
                           agent or employee of University.

         9.2      Both parties agree that upon receipt of a notice of claim or
action arising from activities to be carried out pursuant to the obligations of
this Agreement, the party receiving such notice will notify the other party
promptly.

                            X. INDEPENDENT CONTRACTOR

         For the purposes of this Agreement and all services to be provided
hereunder, the parties shall be, and shall be deemed to be, independent
contractors and not agents or employees of the other party. Neither party shall
have authority to make any statements, representations or

<PAGE>   9



commitments of any kind, or to take any action which shall be binding on the
other party, except as may be expressly provided for herein or authorized in
writing.

                            XI. TERM AND TERMINATION

         11.1     This Agreement shall commence with the Effective Date hereof
and extend until the end of the Research Program as described herein, unless
sooner terminated in accordance with the provisions of this Section ("Term").

         11.2     This Agreement maybe terminated by the mutual agreement of the
parties or by either party upon thirty (30) days written notice, if the
Principal Investigator's tenured appointment with the University terminates and
a suitable replacement (reasonably acceptable to the Sponsor) is not identified.

         11.3     In the event that either party shall be in default of its
material obligations under this Agreement and shall fail to remedy such default
within sixty (60) days after receipt of written notice thereof, the other party
may terminate this Agreement upon expiration of the sixty (60) day period.

         11.4     Termination or cancellation of this Agreement shall not affect

patent maintenance for any patent application or issued patent assigned solely
to University, Sponsor shall notify University prior to abandonment in such a

prosecution of such patent application or issued patent or grant rights to such
patent application or issued patent to third parties.

         If Sponsor chooses not to timely file or pursue patent protection or
patent maintenance for any patent application or issued patent assigned jointly
to Sponsor and University, Sponsor shall, upon University's request, assign its
interests in such patent application or issued patent to University. After such
assignment, such patent application or issued patent shall then not be
considered a Licensed Patent and University shall be free, at its election, to
abandon or maintain the prosecution of such patent application or issued patent
or grant rights to such patent application or issued patent to third parties.

States Patent Application which Sponsor files pursuant to the above.

         VI.      Foreign Filing and Prosecution: Within nine (9) months after
each United States Patent Application is filed pursuant to Paragraph 3 above,
Sponsor shall elect those foreign countries in which Sponsor, after consultation
with University, desires foreign patent protection and Sponsor shall timely file
patent applications in all foreign countries elected. If elected by University,
Sponsor shall file at least in the EPO, Canada and Japan. Sponsor shall, upon
University's request, pursue prosecution of such Licensed Patents in additional
countries at University's expense.

         The Patent Expenses and Costs relating to obtaining, issuing and
maintaining any foreign patent in all foreign countries elected, as provided
above, shall be paid by Sponsor, with reimbursement rights as described above.
If the University so requests, Sponsor shall inform the University of any
significant prosecution events in the elected foreign countries by providing
copies of all prosecution papers and soliciting input into patent office
responses where appropriate.

         VII.     License: Sponsor shall have an exclusive license to University
Patent Rights and University Technology Rights and/or University's ownership
interest in any Joint Patent Rights and Joint Technology Rights to practice any
Invention and use any technology made in the course

the terms of the License Agreement, which is attached as Attachment E.
