                                      -3-
<PAGE>   9

sublicensee of SC shall not be considered a sale; in such cases, Net Sales
shall be determined based on the invoiced sales price by the Affiliate or
permitted sublicensee to its Third Party customer, less the deductions allowed
under this Section.  Every other commercial use or disposition of Products by
SC or its Affiliates or permitted sublicensees of SC in barter or similar
transactions, not including samples, shall be considered a sale of the Products
at the weighted average Net Sales price for Products during the preceding
quarter.

     In the event that a Product is sold in the form of a combination product
containing one or more active ingredients other than a component whose
discovery or development was Enabled by GTC (a "Combination Product"), Net
Sales for such Combination Product will be calculated by multiplying actual Net
Sales of such Combination Product by the fraction A/(A+B), where A is the
invoice price of the Product if sold separately by SC, an Affiliate or a
sublicensee and containing a component whose discovery or development was
Enabled by GTC as the only active ingredient and B is the invoice price of any
other active component or components in the Combination Product if sold
separately by SC, an Affiliate or a sublicensee.  In the event that the Product
is sold in the form of a Combination Product containing one or more active
ingredients other than a component whose discovery or development was Enabled
by GTC and one or more such active ingredients of the Combination Product are
not sold separately, then the above formula shall be modified such that A shall
be the total manufacturing cost to SC, its Affiliate or sublicensee of the
Product and B shall be the total manufacturing cost to SC, its Affiliate,
sublicensee or other supplier of any other active component or components in
the Combination Product.  Notwithstanding the foregoing, (i) biologically
active ingredients shall not include diluents, vehicles or adjuvants and (ii)
in no event shall Net Sales for any Combination Product calculated under this
provision be less than fifty percent of the invoice price of such Combination
Product.

     In the event that SC, its Affiliates or permitted sublicensees sell
Products pursuant to an agreement with an independent customer specifying, for
a combination of products or services, a single price, other terms of purchase
not separately identifying either a price per product or the effective
deductions referred to above per product or a price for units of the Products
which is discounted below SC's, its Affiliates' or its permitted sublicensee's
standard invoice price per unit of the Products by at least five (5) percentage
points more than the amount that any other product or service included in the
arrangement is discounted below such other product's or service's standard
invoice price, then GTC and SC will determine a mutually agreeable method of
calculation so that a fair and reasonable portion of the aggregate purchase
price is allocated to the Product(s) included in any such arrangement.

     1.19. "OTHER PRODUCT" shall mean any product which is based upon genes
or proteins contained in the GTC Database, other than a Diagnostic Product,
Pharmaceutical Product or Vaccine Product, and which (i) contains a component
which is covered by one or more Valid Claims included within the Product Patent
Rights or (ii) contains a component whose discovery or
development was Enabled by GTC.

     1.20. "OVERALL RESEARCH PLAN" shall mean the research plan agreed upon
by the Joint Research Committee pursuant to Section 4.6.1 hereof, as it may be
subsequently amended, improved or modified from time to time, the draft of
which is attached hereto as EXHIBIT A1 (the "Draft Overall Research Plan").

     1.21. "PHARMACEUTICAL PRODUCT" shall mean any product used to treat
disease (whether related to     *      or    * or not) which (i) contains a
component which is covered by one or more Valid Claims included within the
Product Patent Rights or (ii) contains a component whose discovery or
development was Enabled by GTC.

     1.22. "PHARMACEUTICAL PRODUCT CLASS" shall mean any one of the
following three classes of Pharmaceutical Products: (i) broad spectrum
antibiotics; (ii) narrow spectrum antibiotics; and (iii)      *      products.

     1.23. "PRODUCT" shall mean collectively Pharmaceutical Products,
Vaccine Products, Other Products, or any one or more of them, but shall not
include Diagnostic Products.

     1.24. "PRODUCT CATEGORY" shall mean any one of the following two
categories of Products: (i) Pharmaceutical Products, including products in any
Pharmaceutical Product Class, and (ii) Vaccine Products.

     1.25. "PRODUCT PATENT RIGHTS" shall mean (a) the United States and
foreign patent applications filed covering Products (including components
thereof) or biological targets discovered and/or developed during the course of
the Research Collaboration or during the course of SC's performance of its
development obligations under Article 5 of this Agreement, (b) any United
States patents and foreign patents issuing from such patent applications and
(c) any continuations, continuations-in-part directed to subject matter
specifically described in such patent applications, divisionals, reissues or
extensions of any of the foregoing.  Product Patent Rights shall not include
any of the foregoing to the extent that they are specifically directed to and
cover Diagnostic Products.

     1.26. "RESEARCH COLLABORATION" shall mean the period of time during

Collaboration within        *        after GTC's release of such software.
After the end of the Research Collaboration and prior to the termination of the
Agreement, SC may request, and GTC agrees to furnish, updates of the GTC 
Databases, including annotations, and new releases of GTC Software upon such 
terms and conditions, including the payment by SC of fair and reasonable 
additional consideration therefor, as may be negotiated in good faith by GTC 
and SC at the time of any such request.

     4.2. ACCESS TO DATA, INFORMATION EXCHANGE AND REPORTS.   SC will have
direct access to raw sequence data that form part of the GTC Databases and to
other work resulting from the Research Collaboration including, but not limited
to, targeted sequencing data, comparative sequence data, gene mapping,
representational difference analysis data, gene expression and protein
expression data, gene mutation data, molecular genetic methodologies and
technologies, protein purification procedures and biochemical assay
methodologies.  Except for electronic access via a computer network pursuant to
Section 4.3 hereof, SC's access shall be during normal business hours and upon
reasonable notice, granting SC treatment and priority not less favorable than
granted to GTC's other collaborators.

     During the Research Collaboration and thereafter, each party shall keep
the other informed as to its progress related to the development of Products by
either party or its Affiliates or sublicensees in connection with the Research
Collaboration.  In a timely manner during the Research Collaboration, each
party shall provide the other party with a reasonably detailed report which
shall describe the reporting party's progress with respect to its efforts under
this Agreement.

     4.3. ELECTRONIC ACCESS TO SCIENTIFIC DATA. To the extent practicable, SC's
access to scientific data contemplated by Section 4.2 will at all times be, at
the expense of SC, via electronic computer network with twenty-four (24) hours
accessibility except for downtime required to maintain or otherwise service the
database and under unforeseen circumstances; provided, however, that SC shall
take such measures to insure the security of such computer link as GTC shall
reasonably request, including, without limitation, restricting access thereto
and regulating the information communicated pursuant thereto for purposes of
maintaining confidentiality.  In addition to electronic access via a computer
network, SC shall be entitled to install and maintain for the term of this
Agreement electronic copies of the GTC Databases and any updates thereto on
computers maintained by SC at SC facilities; provided, however, that prior to
any such installation GTC and SC shall agreed upon reasonable

security measures to be instituted by SC to protect the GTC Databases from
access by Third Parties.

     4.4. LEVEL OF EFFORT BY GTC SCIENTISTS.  The Research Collaboration shall
continue for a minimum term of            * Contract Years and may be extended,
at the option of SC, for a total term of     *     Contract Years.   During the
first Contract Year, GTC will provide        *         scientist man-years of 
effort (including bioinformatics) for the Research Collaboration.  During the
        *, GTC will provide *                     *   scientist man-years of 
effort (including bioinformatics) for the Research Collaboration.  After 
completion of the    *    Contract Year, (i) if SC does not elect to extend the
Research Collaboration, the number of GTC scientist man-years (including 
bioinformatics) committed to the Research Collaboration shall continue at a 
minimum of       *     for the final   *           *      of the Research 
Collaboration, subject to GTC's right to engage in an orderly wind-down 
pursuant to Section 11.1.1 hereof, and (ii) if SC elects to extend the Research 
Collaboration to a total term of     *     Contract Years, the number of GTC 
scientist man-years (including bioinformatics) committed to the Research 
Collaboration during each of the       *    and    *    Contract Years shall be 
a minimum of     *      .  Any number of scientist man-years in excess of the 
minimum applicable to any Contract Year shall be subject to the mutual 
agreement of GTC and SC.

           4.6.2. ANNUAL RESEARCH PLANS.  Within forty-five (45) days after
the Effective Date, the Joint Research Committee shall agree upon a written
plan for the specific activities to be conducted in connection with the
Research Collaboration during calendar year 1996 (the "Annual Research Plan").
Thereafter, by October 1 of each year during the Research Collaboration
beginning with October 1, 1996, GTC shall submit to the Joint Research
Committee a written proposed Annual Research Plan for the following calendar
year.  The Joint Research Committee shall review each such proposal as soon as
practicable and shall approve no later than December 31 of such year the final
Annual Research Plan for the next succeeding calendar year.

           4.6.3. PERIODIC REVIEWS.  The Joint Research Committee shall
review the Overall Research Plan on an ongoing basis and may make changes to
the Annual Research Plan then in effect; provided, however, the Annual Research
Plan then in effect shall not be modified except as agreed in writing by the
Joint Research Committee.

           4.6.4. MEMBERSHIP OF JOINT RESEARCH COMMITTEE.  The Joint Research
Committee shall be comprised of three (3) representatives from each of SC and
GTC, with each party's members to be selected by that party.  GTC and SC may
replace one or more of its representatives on the Joint Research Committee at
any time upon written notice to the other party.  Unless the parties otherwise
agree, the chairmanship of the Joint Research Committee shall rotate at the end
of each Contract Year between a representative of GTC and a representative of
SC, with a representative of GTC serving as chairman during the first Contract
Year.  From time to time the Joint Research Committee may establish
subcommittees to oversee particular projects or activities, and such
subcommittees will be constituted as the Joint Research Committee shall agree.

           4.6.5. JOINT RESEARCH COMMITTEE MEETINGS.  The Joint Research
Committee shall meet six (6) time per year at regular intervals during the term
of the Research Collaboration, or more often as agreed upon by both parties, at
such locations as the parties may agree upon.  Regularly scheduled meetings or
special meetings of the Joint Research Team may be in such form (e.g. in
person, by telephone or by video conference) as the members of the Joint
Research Committee shall agree.  At such meetings, the Joint Research Committee
shall formulate and review the objectives of the Research Collaboration as
expressed in the Overall Research Plan, monitor the progress of the Annual
Research Plan toward those objectives and take such other actions as may be
specified under this Agreement or as the parties may deem appropriate.  With
the consent of both parties, other representatives of GTC or SC or their
respective Affiliates or, in the case of SC and its Affiliated, their
sublicensees, may attend the meetings of the Joint Research Committee as
nonvoting observers.  Each party shall be responsible for all expenses of its
representatives on the Joint Research Committee.  The Joint Research Committee
shall keep accurate minutes of its deliberations which shall record all
proposed decisions and all actions recommended or taken and which shall be
countersigned by one representative of each party.  All records of the Joint
Research Committee shall be available to both parties.

           4.6.6. DECISION MAKING.  Any approval, determination or other
action agreed to by all members of the Joint Research Committee or their

<PAGE>   17

action of the entire Joint Research Committee.  Except as otherwise agreed, all
decisions require the approval of all of the representatives of each party,
regardless of the number of such representatives present.  The Joint Research
Committee may, however, delegate to one party or to a specific representative
the authority to make certain decisions.  In the event of a dispute within the
Joint Research Committee, if the members of the Joint Research Committee are
unable to resolve such dispute after engaging in good faith negotiations for
thirty (30) days, then such dispute shall be resolved in accordance with
Section 13.6 hereof.

     4.7. JOINT PATENT COMMITTEE.  A joint committee comprised of one (1) named
representatives of each party (the "Joint Patent Committee") shall be appointed
and shall meet as needed.  A party may change one or more of its
representatives to the Joint Patent Committee at any time.  Members of the
Joint Patent Committee may be represented at any meeting by another member of
the Joint Patent Committee, or by a deputy.  Additional members of the Joint
Patent Committee may be appointed on an ad hoc basis upon the mutual consent of
the parties.  The Joint Patent Committee shall formulate and supervise the
execution of an intellectual property protection strategy with regard to all
matters in connection with the Research Collaboration.  In any instance in
which GTC informs SC in writing that it objects to the filing of any patent
application by SC, the filing of such application shall be subject to the prior
written approval of the Joint Patent Committee.   The policies and procedures
set forth in Section 4.6.6 shall apply to the Joint Patent Committee and
references to the Joint Research Committee made therein shall be deemed to
refer to the Joint Patent Committee for purposes of this Section 4.7.


             ARTICLE 5.  DEVELOPMENT AND MARKETING DUE DILIGENCE

     5.1. DILIGENT DISCOVERY EFFORTS.  SC agrees, at its own expense, to use
diligent efforts to use the GTC Databases, GTC Technology and GTC Software to
discover one or more Lead Compounds for each Product Category.  Such diligent
efforts shall be comparable to those efforts used by SC for other SC discovery
programs with comparable commercial potential, value and development status. 
Without limiting the foregoing, SC will at a minimum (i) pursue diligent
efforts to screen representative compounds, not previously tested, from SC's    
in-house synthetic and natural product libraries against genomic targets
identified by GTC during the Research Collaboration and (ii) in each twelve-
month period following the end of Research Collaboration, either (a) screen not
less than      *     * new representative compounds, not previously tested,
against genomic targets identified by GTC during the Research Collaboration or
(b) if new assay development is required, commit at least      *      full time
equivalent scientists to assay development; provided, however, that such
minimum screening effort may be suspended in whole or in part at the sole
discretion of SC during any  period in which SC is actively developing    *
*    Lead  Compounds or Development Candidates for each Product Category.

     5.2. DILIGENT DEVELOPMENT EFFORTS.  SC agrees, at its own expense, to use
diligent efforts to develop and commercialize, either directly or through its
Affiliates or permitted sublicensees, the Lead Compounds and Development
Candidates selected by it pursuant to Section 5.1.  Such diligent efforts shall
be comparable to those efforts used by SC for other SC product candidates with
comparable commercial potential, value and development status 



*  Confidential information omitted and filed separately with the Commission


                                    -12-

and shall include the active conduct of in vivo toxicology trials necessary to
obtain approval for use of such compound in human clinical trials or the active
conduct of human clinical trials, in each case for at least one Lead Compound
or Development Candidate in each Product Category.  The selection of Lead
Compounds and Development Compounds for development and commercialization shall
be in the sole discretion of SC.  SC, its Affiliates and permitted sublicensees
may, but shall have no obligation under this Agreement to, develop and
commercialize more than       *        in each Product Category at any time
during the term of this Agreement.  If SC discontinues development of a Lead
Compound or Development Candidate, SC will resume the diligent screening
efforts described in Section 5.1 with the objective of selecting a replacement
Lead Compound or Development Candidate, as the case may be, and maintaining at  
least                          * under active pre-clinical or clinical
development in each Product Category.  Such diligent development efforts will
continue until marketing approval has been obtained for at least one Product in
each Product Category in each Major Market Country.

     5.3. DILIGENT MARKETING AND DISTRIBUTION EFFORTS.  SC shall have the
exclusive worldwide right to market and distribute the Products.  Upon receipt
of approval for commercial sale of a Product in any country, SC agrees, at its
own expense, to use diligent efforts to launch, promote, market and sell such
Product in such country.  Such efforts shall be comparable to those efforts
used by SC to promote its own products of similar commercial potential, value
and development status in such country or a comparable country, as the case may
be.  Both parties recognize that extenuating circumstances may arise that
warrant a delay in launching a Product in a particular country, including but
not limited to unfavorable pricing, pricing reimbursement or labelling of the
Product in such country.  The parties agree that such extenuating circumstances
shall be considered in connection with any determination concerning whether SC
has fulfilled its obligation to use diligent efforts to launch, promote, market
and sell such Product in such country.

     5.4. REPORTS.  After the expiration or termination of the Research
Collaboration, SC shall provide GTC with reasonably detailed reports which
shall describe SC's progress with respect to its development, commercialization
and marketing efforts under this Agreement.  Such reports shall be furnished
semi-annually for the first five (5) years after the expiration or
termination of the Research Collaboration and annually thereafter.

     6.3. Research Funding.
          ----------------

          6.3.1. FUNDING DURING FIRST   *   CONTRACT YEARS.  During the
first    *   Contract Years, SC will pay GTC      * United States dollars per
year by certified or bank check or wire transfer for funding of the sponsored
research outlined in the Overall Research Plan.  Such amounts shall be payable
in advance in four quarterly payments of              *      United States
dollars each, with the first quarterly payment due within fifteen (15) days
after the Funding Commencement Date.  In the event that the parties agree to
exceed the number of scientist man-years set forth in Section 4.4 hereof in
*    of the first *   Contract Years, in addition to the amounts set forth in
this Sections 6.3.1, SC shall reimburse GTC at the rate of     * United States
dollars per man-year for each such additional scientist (including
bioinformatics) engaged in the Research Collaboration.  Such payments shall be
made in accordance with the procedure set forth in Section 6.3.2.

          6.3.2. FUNDING AFTER THE     *     CONTRACT YEAR.  After the
completion of the      *     Contract Year, SC will reimburse GTC at the rate
of      *      United States dollars per man-year for each scientist 
(including bioinformatics) engaged in the Research Collaboration, such
reimbursement to be indexed to reflect changes in GTC's actual cost of
performing research during the first    *   Contract Years.  Reimbursements
will be payable by certified or bank check or wire transfer in advance of each
quarter of such Contract Year in which the work is to be performed based on
reasonable estimates.  Payments for partial quarters shall be prorated.  After
the completion of the *       Contract Year, GTC will, within forty-five (45)
days after the end of each quarter of a Contract Year, provide SC with a
written report specifying the scientists engaged in the Research Collaboration,
the time devoted thereto by each of them during the preceding quarter, a
calculation of the amount due to GTC from SC for such   quarter and the debit
or credit balance at the end of such quarter.  Debit balances shall reduce the
estimated payment to be made by SC for work under the Research Collaboration in
the next quarter and credit balances shall be paid by SC to GTC within fifteen
(15) days after the receipt of GTC's written report.

          6.3.3. ADDITIONAL EXPENDITURES.  In the event that the scope,
scale or direction of the Research Collaboration as described in the draft
Overall Research Plan attached hereto as EXHIBIT A1 changes after the Effective
Date, any additional expenditures required to be made by GTC to support the
Research Collaboration shall be funded by SC.  All changes in the scope, scale
or direction of the Research Collaboration which may trigger additional funding
by SC shall be approved in advance by the Joint Research Committee.  If such

*  Confidential information omitted and filed separately with the Commission

                                    -15-
<PAGE>   21

additional payments relate to items of capital equipment or Third Party
software which are reasonably anticipated to be used by GTC to a greater extent
outside the Research Collaboration than within the Research Collaboration, then
GTC and SC shall negotiate in good faith regarding the allocation of such costs
between GTC and SC; provided, however, that GTC cannot not be required to
contribute to such costs without its consent.  Any payments which become due
under this Subsection shall be made in United States dollars quarterly in
advance by certified or bank check or wire transfer.

     6.4. ROYALTIES PAYABLE BY SC AND ITS AFFILIATES AND SUBLICENSEES.
Following the First Commercial Sale of any Product, SC will pay, on a quarterly
basis, a royalty in the amounts set forth below on Net Sales of the Products
during the previous quarter.

          6.4.1. ROYALTIES ON NET SALES OF THE PRODUCTS.  In consideration
of the licenses granted to SC, SC shall pay to GTC a royalty in the amount of
(i)           *              on cumulative Net Sales by SC, its Affiliates and
sublicensees of less than        *         and (ii)            *            on
cumulative Net Sales by SC, its Affiliates and sublicensees equal to or greater
than      *      .  In the event that a Product comprises a Lead Compound or
derivatives or analogues thereof initially discovered to have activity against
a GTC-identified target during the first    *    Contract Years, the royalty
rate on Net Sales of such Product payable pursuant to the preceding sentence 
shall be increased by          *         .

          6.4.2. SUBLICENSES.  If SC grants a sublicense hereunder to any
Third Party to make, have made, use, or sell Products in any country, SC shall
(i) pay to GTC       * *        of the fair market value of all consideration
received by SC from such Third Party in connection therewith which are not
based upon Net Sales of the Products by such Third Party in such country and
(ii)(A) pay to GTC royalties on Net Sales of the Products sold by such Third
Party in such country or (B) provide in such sublicense that such sublicensee
shall pay to GTC royalties on Net Sales of the Products sold by such
sublicensee in such country, in either case at the royalty rate set forth in
Section 6.4 that would be applicable had such sales been made by SC, and
provided that in either case, SC shall remain liable for the timely payment of
all such royalties.

          6.4.3. ADJUSTMENTS FOR THIRD PARTY ROYALTIES.  If SC is required
to pay royalties and/or lump sum license fees to Third Parties for rights under
patents necessary to make or sell the Products, it may deduct an amount equal
to up to *               of such royalties and/or lump sum license fees from
the royalties due GTC under Section 6.4, provided, however that the aggregate
royalties due to GTC under this Agreement may not be reduced by more than
*               in any given quarter by all deductions or credits allowed under
this Agreement.

          6.4.4. ROYALTY REPORTS, EXCHANGE RATES.  During the term of this
Agreement following the First Commercial Sale of any Product, SC shall within
sixty (60) days after each calendar quarter furnish to GTC a written quarterly
report showing:  (i) the gross sales of the Products sold by SC and its
Affiliates and sublicensees during the reporting period and the calculation of
Net Sales from such gross sales; (ii) the sublicense payments received by SC
during the reporting period; (iii) the royalties and other payments payable in
United States dollars which shall have accrued hereunder in respect of such
sales and sublicense

payments; (iv) withholding taxes, if any, required by law to be deducted in
respect of such royalties and sublicense payments; (v) the dates of the
First Commercial Sales of Products in any country during the reporting period;
and (iv) the exchange rates used in determining the amount of United States
dollars payable hereunder.  Royalties payable on sales in countries other than
the United States shall be calculated by multiplying the appropriate royalty
rate times the sales in each currency in which they are made and converting the
resulting amount into United States dollars at the rates of exchange used by SC
for reporting such sales for United States financial statement purposes.  If no
royalty or payment is due for any royalty period hereunder, SC shall so report. 
SC shall keep complete and accurate records in sufficient detail to properly
reflect all gross sales and Net Sales and to enable the royalties payable
hereunder to be determined.

           6.4.5. AUDITS.  Upon the written request of GTC, SC shall permit
an independent certified public accountant selected by GTC and acceptable to
SC, which acceptance shall not be unreasonably withheld, to have access during
normal business hours to such records of SC as may be reasonably necessary to
verify the accuracy of the royalty reports described herein, in respect of any
fiscal year ending not more than twenty-four (24) months prior to the date of
such request.  GTC and SC shall use commercially reasonable efforts to schedule
all such verifications within forty-five (45) days after GTC makes its written
request.  All such verifications shall be conducted at GTC's expense and not
more than once in each calendar year.  In the event GTC's independent certified
public accountant concludes that additional royalties were owed to GTC during
such period, the additional royalty shall be paid by SC within thirty (30) days
of the date GTC delivers to SC such independent certified public accountant's
written report so concluding.  In the event GTC's independent certified public
accountant concludes that there was an overpayment of royalties to GTC during
such period, the overpayment less the reasonable fees and expenses charged by
such representative shall be repaid by GTC within thirty (30) days of the date
GTC received such independent certified public accountant's written report so
concluding.  The fees charged by such independent certified public accountant
shall be paid by GTC unless the audit discloses an underpayment of the
royalties payable by SC for the audited period of more than five percent (5%),
in which case SC shall pay the reasonable fees and expenses charged by such
representative.  SC shall include in each Third Party sublicense granted by it
pursuant to this Agreement a provision requiring the sublicensee to make
reports to SC, to keep and maintain records of sales made pursuant to such
sublicense and to grant access to such records by GTC's independent certified
public accountant to the same extent required of SC under this Agreement.  GTC
agrees that all information subject to review under this Section 6.4.5 or under
any sublicense agreement is confidential and that GTC shall cause its
independent certified public accountant to retain all such information in
confidence.  GTC's independent certified public accountant shall only report to
GTC as to the computation of the royalties and other payments due to GTC under
this Agreement and shall not disclose to GTC any other information of SC or its
sublicensees.

           6.4.6. ROYALTY PAYMENT TERMS.  Royalties shown to have accrued by
each royalty report provided for under this Agreement shall be due sixty (60)
days after the end of each calendar quarter.  Payment of royalties in whole or
in part may be made in advance of such due date.  Royalties determined to be
owing with respect to any prior quarter shall be added, together with interest
thereon accruing under this Agreement from the date of the


                                    -17-
<PAGE>   23

report for the quarter for which such amounts are owing, to the next quarterly 
payment hereunder.

     6.5. ROYALTIES PAYABLE BY GTC.  Following the First Commercial Sale of any
Other Product by GTC or its Affiliates, GTC will pay to Schering Corporation,
on a quarterly basis, a royalty in the amount of        *          on Net
Sales, subject to the terms and conditions of Sections 1.19, 6.4.3 through
6.4.6, and 6.6 through 6.8 hereof.  For purposes of this Section 6.5, all
references to SC in the aforementioned sections of this Agreement shall be
deemed to refer to GTC and vice-versa.

     6.6. WITHHOLDING TAXES.  SC shall                * 
                                        * 
     *     .  SC shall                          * 
                        *                               including but not 
limited to any such taxes or charges    incurred as a result of an assignment
or sublicense by SC to any Affiliate or any Third Party                *
 .  SC shall           * 
            * 
The parties will exercise their best efforts to ensure that any withholding 
taxes imposed are reduced as far as possible under the provisions of any 
treaties applicable to any payment made hereunder.

     6.7. BLOCKED CURRENCY.  If transfer of amounts payable hereunder to United
States dollars is subject to administrative authorization, SC shall promptly
file the transfer application with the competent authorities supported by all
requisite documentation, and use its reasonable efforts to obtain such
authorization and effect the remittance within the applicable period set forth
under this Article 6; provided, however, that nothing in this Section 6.7 shall
relieve SC from its obligation to pay any amounts payable hereunder within the
applicable period set forth under this Article 6.

     6.8. ALLOCATION OF PAYMENTS BY SC.  Fifty percent (50%) of all payments to
be made by SC to GTC pursuant to this Article 6 shall be paid by Schering
Corporation and the balance shall be paid by Schering-Plough Ltd.; provided,
however, that Schering Corporation and Schering-Plough Ltd. are jointly and
severally liable for any and all amounts payable by SC to GTC pursuant to this
Article 6.

     6.9. INTEREST ON LATE PAYMENTS.  Any payments by SC to GTC that are not
paid on or before thirty (30) days after the date such payments are due under
this Agreement shall bear interest, to the extent permitted by applicable law,
at one and one half percent (1.5%) per month, calculated on the total number of
days payment is delinquent; provided, however, that interest shall not accrue
pursuant to this Section 6.8 on any amounts payable under this Agreement with
respect to which payment is disputed in good faith; provided further that 
interest shall accrue pursuant to this Section 6.8 once such dispute has been 
resolved if payment is not made promptly thereafter.

                      ARTICLE 7.  INTELLECTUAL PROPERTY

     7.1. OWNERSHIP OF INTELLECTUAL PROPERTY.  Subject to the rights and
licenses granted under this Agreement (i) GTC shall retain ownership of the GTC
Databases, the GTC Technology and the GTC Software and (ii) SC shall retain
ownership of the SC Assay Technology and Product Patent Rights.

     7.2. Filing, Prosecution and Maintenance of Product Patent Rights.
          ------------------------------------------------------------

          7.2.1.    PROSECUTION AND MAINTENANCE OF PRODUCT PATENT RIGHTS.  SC
shall be responsible for the filing, prosecution (including oppositions) and
maintenance of the Product Patent Rights at its expense in its own name;
provided, however, that the filing, prosecution (including oppositions) and
maintenance of Product Patent Rights relating to Other Products shall be at
SC's expense in GTC's name.  SC shall consult with GTC and keep GTC fully
informed of important issues relating to the preparation, filing, prosecution
and maintenance of such patent applications and the patents related thereto,
including SC's patent strategy with respect to both existing and future patent
applications, patents and patent extensions, and shall furnish to GTC copies of
documents relevant to such preparation or filing (such copies of documents with
respect to initial patent filings to be furnished to GTC sufficiently prior to
filing such document or making any payment due thereunder to allow for review
and comment by GTC, and SC shall seriously consider all GTC comments on such
initial patent filings) and, upon GTC's request, copies of documents relevant
to such prosecution or maintenance; and provided, further, that in any instance
in which GTC informs SC in writing that it objects to the filing of any patent
application by SC, the filing of such application shall be subject to the prior
written approval of the Joint Patent Committee pursuant to Section 4.7 hereof.
If SC elects not to continue to seek or maintain patent protection on any
patent or patent application included in the Product Patent Rights in any
country, GTC shall have the right, at its option and expense, with the
reasonable assistance of SC to file, prosecute (including oppositions) and
maintain such patent applications and patents; provided, however, that the
rights of the parties with respect to any such Product Patent Rights shall in
all other respects be as described in this Agreement.  SC will advise GTC of
all decisions taken with respect to any such election in a timely manner in
order to allow GTC to protect its rights under this Section 7.1.1.

          7.2.2.    ABANDONMENT; FAILURE TO PAY.  SC agrees that it will not
abandon the prosecution of any patent applications included within the Product
Patent Rights nor shall it fail to make any payment or fail to take any other 
action necessary to maintain a patent under the Product Patent Rights unless 
it has notified GTC in sufficient time for GTC to assume such prosecution or 
make such payment.

          7.2.3.    COOPERATION.  Each party shall make available to the other
party (or to the other party's authorized attorneys, agents or
representatives), its employees, agents or consultants to the extent reasonably
necessary or appropriate to enable the appropriate party to file, prosecute and
maintain patent applications and resulting patents as set forth in this Section
7.1 for periods of time reasonably sufficient for such party to obtain the
assistance it needs from such personnel.  Where appropriate, each party shall
sign or cause to have signed all documents relating to said patent applications
or patents at no charge to the other party.

<PAGE>   25

     7.3. INFRINGEMENT BY OTHERS; PROSECUTION BY SC.  GTC and SC shall each
promptly notify the other in writing of any alleged or threatened infringement
of patents or patent applications included in the Product Patent Rights of
which they become aware, and the parties shall consult concerning the action to
be taken.  SC shall have the right, but not the obligation, to prosecute at its
own expense any such infringement.  Any recovery or damages derived from such
action shall be used (i) first to reimburse SC for all legal expenses relating
to the suit and (ii) second to pay GTC the royalty it would have been entitled
to receive had the sale of such infringing products been sales of Products
licensed by SC hereunder.     *
                *                                  .

     7.4. INFRINGEMENT BY OTHERS; PROSECUTION BY GTC.  If, within six (6)
months after SC first becomes aware of any infringement of the Product Patent
Rights, SC fails to cause such infringement to terminate or to bring a suit or
action to compel termination, GTC shall have the right, but not the obligation,
to bring such suit or action to compel termination at the sole expense of GTC.
In such event, GTC shall have the right, if SC is a legally indispensable
party, to bring such suit or action in the name of SC.  Any recovery or damages
in such suit shall be retained by GTC.

     SC shall have the right, prior to the commencement of the trial of any
suit or action brought by GTC, to join any such suit or action and, in such
event, shall pay one-half of the entire cost of such suit or action.  Provided
that SC has joined in the action and shared the costs thereof as stated in the
preceding sentence, no settlement, consent judgment or other voluntary final
disposition of the suit may be entered into without the consent of SC, which
consent shall not unreasonably be withheld.  Any recovery or damages derived
from such action shall be used (i) first to reimburse GTC for all legal
expenses relating to the suit and (ii) second to pay GTC the royalty it would
have been entitled to receive had the sale of such infringing products been
sales of Products licensed by SC hereunder.                * *    of any
remaining recovery or damages shall thereafter be retained by GTC and the
balance shall be distributed to SC.

     7.5. COOPERATION IN INFRINGEMENT ACTIONS.  In any infringement suit which
either party may institute to enforce the Product Patent Rights pursuant to
this Agreement, the other party hereto shall, at the request of the party
initiating such suit, cooperate in all respects and, to the extent possible,
have its employees testify when requested and make available relevant records,
papers, information, samples and the like.  GTC's cooperation in any suit
initiated by SC shall be at SC's expense.  SC's cooperation in any suit
initiated by GTC shall be at GTC's expense.

     7.6. TRADEMARKS.  SC shall be free to use and to register in any trademark
office in the world any trademark for use with Products it desires in its sole
discretion.  SC shall own all right, title and interest in and to any such
trademark in its own name or that of its designated Affiliate during and after
the term of this Agreement.

thereafter, the parties shall maintain in confidence and use only for purposes
specifically authorized under this Agreement (i) GTC Databases, (ii) the SC
Assay Technology, (iii) any other information and data received from the other
party resulting from or related to the Research Collaboration and the Products
and (iv) all information and data not described in clauses (i), (ii) or (iii)
but supplied by the other party under this Agreement marked "Confidential."
For purposes of this Article 8, information and data described in clauses (i),
(ii), (iii) or (iv) shall be referred to as "Information."

          8.1.2. LIMITATIONS.  To the extent it is reasonably necessary or
appropriate to fulfill its obligations or exercise its rights under this
Agreement: (i) a party may disclose Information it is otherwise obligated under
this Section 8.1 not to disclose to its Affiliates, sublicensees, consultants,
outside contractors and clinical investigators, on a need-to-know basis and on
condition that such entities or persons agree to keep the Information
confidential for the same time periods and to the same extent as such party is
required to keep the Information confidential; and (ii) a party or its
sublicensees may disclose such Information to government or other regulatory
authorities to the extent that such disclosure is reasonably necessary to
obtain patents or authorizations to conduct clinical trials of, and to
commercially market, Products pursuant to this Agreement.  The obligation not
to disclose Information shall not apply to any part of such Information that:
(i) is or becomes part of the public domain other than by unauthorized acts of
the party obligated not to disclose such Information or its Affiliates or 
sublicensees; (ii) can be shown by written documents to have been disclosed to 
the receiving party or its Affiliates or sublicensees by a Third Party, 
provided such Information was not obtained by such Third Party directly or 
indirectly from the other party to this Agreement pursuant to a confidentiality
agreement; (iii) prior to disclosure under this Agreement, was already in the 
possession of the receiving party or its Affiliates or sublicensees, provided 
such Information was not obtained directly or indirectly from the other party to
this Agreement pursuant to a confidentiality agreement; (iv) can be shown by
written documents to have been independently developed by the receiving party
or its Affiliates without breach of any of the provisions of this Agreement; or
(v) is disclosed by the receiving party pursuant to interrogatories, requests
for information or documents, subpoena, civil investigative demand issued by a
court or governmental agency or as otherwise required by law, provided,
however, that the receiving party notifies the other party immediately upon
receipt thereof, giving such other party sufficient advance notice to permit it
to seek a protective order or other similar order with respect to such
Information and provided, further, that the disclosing party furnishes only
that portion of the Information which it is advised by counsel is legally
required whether or not a protective order or other similar order is obtained
by the other party.

     8.2. SAMPLES. Samples of genes, other biological targets, antigens or
compounds identified, sequenced, synthesized, purified or developed in the
course of the Research Collaboration shall not be supplied or sent by either
party to any Third Party, other than to




                                      -21-

regulatory agencies or for use in clinical trials, unless such release is
approved by a member of the Joint Research Committee from the other party and
protected by an appropriate materials transfer agreement substantially similar
to the form of Material Transfer Agreement attached hereto as EXHIBIT C.
Samples of materials other than those described above provided by one party
(the "supplying party") to the other party (the "receiving party") in the
course of the Research Collaboration shall not be supplied or sent by the
receiving party to any Third Party, other than to regulatory agencies or for
use in clinical trials, without the written consent of the supplying party.

     8.3. INJUNCTIVE RELIEF.  The parties hereto understand and agree that
remedies at law may be inadequate to protect against any breach of any of the
provisions of this Article 8 by either party or their employees, agents,
officers or directors or any other person acting in concert with it or on its
behalf.  Accordingly, each party shall be entitled to the granting of
injunctive relief by a court of competent jurisdiction against any action that
constitutes any such breach of this Article 8.

PRODUCT PATENT RIGHTS, GOODS, SERVICES OR OTHER SUBJECT MATTER OF THIS AGREEMENT
AND HEREBY DISCLAIMS WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR 
PURPOSE AND NONINFRINGEMENT WITH RESPECT TO ANY AND ALL OF THE FOREGOING.

     9.5. LIMITED LIABILITY.  NOTWITHSTANDING ANYTHING ELSE IN THIS AGREEMENT
OR OTHERWISE TO THE CONTRARY, NEITHER GTC NOR SC WILL BE LIABLE WITH RESPECT TO
ANY SUBJECT MATTER OF THIS AGREEMENT UNDER ANY CONTRACT, NEGLIGENCE, STRICT

OF SUBSTITUTE GOODS, TECHNOLOGY OR SERVICES.


                             ARTICLE 10.  INDEMNITY

    10.1. SC INDEMNITY OBLIGATIONS.  SC agrees to defend, indemnify and
hold GTC, its Affiliates and their respective employees and agents harmless
from all claims, losses, damages or expenses arising as a result of:  (a)
actual or asserted violations of any applicable law or regulation by SC, its
Affiliates or sublicensees by virtue of which the Products manufactured,
distributed or sold hereunder shall be alleged or determined to be adulterated,
misbranded, mislabeled or otherwise not in compliance with any applicable law
or regulation; (b) claims for bodily injury, death or property damage
attributable to the manufacture, distribution, sale or use of the Products by
SC, its Affiliates or sublicensees; or (c) a Product recall ordered by a
governmental agency or required by a confirmed Product failure as reasonably
determined by the parties hereto.

    10.2. LIMITATION ON SC INDEMNITY OBLIGATIONS.  GTC, its Affiliates and
their respective employees and agents shall not be entitled to the indemnities
set forth in Section 10.1 where the claim, loss, damage or expense for which
indemnification is sought was caused by a grossly negligent or intentional act
or omission by GTC, its directors, officers, employees or authorized agents.

    10.3. PROCEDURE.  If GTC or any of its Affiliates or their respective
employees or agents (the "Indemnitee") intends to claim indemnification under
this Article 10, the Indemnitee shall promptly notify the other party (the
"Indemnitor") of any loss, claim, damage, liability or action in respect of 
which the Indemnitee intends to claim such indemnification, and the Indemnitor  
shall assume the defense thereof with counsel mutually satisfactory to the
parties; provided, however, that an Indemnitee shall have the right to retain
its own counsel, with the fees and expenses to be paid by the Indemnitor, if
representation of such Indemnitee by the counsel retained by the Indemnitor
would be inappropriate due to actual or potential differing interests between
such Indemnitee and any other party represented by such counsel in such
proceedings. The indemnity agreement in this Article 10 shall not apply to
amounts paid in settlement of any loss, claim, damage, liability or action if
such settlement is effected without the consent of the Indemnitor, which consent
shall not be withheld unreasonably.  The failure to deliver notice to the
Indemnitor within a reasonable time after the commencement of any such action,
if prejudicial to its ability to defend such




                                      -24-
<PAGE>   30

action, shall relieve such Indemnitor of any liability to the Indemnitee under
this Article 10, but the omission so to deliver notice to the Indemnitor will
not relieve it of any liability that it may have to any Indemnitee otherwise
than under this Article 10.  The Indemnitee under this Article 10, its
employees and agents, shall cooperate fully with the Indemnitor and its legal
representatives in the investigation of any action, claim or liability covered
by this indemnification.  The Indemnitor shall additionally be liable to pay
the reasonable legal costs and attorneys' fees incurred by the Indemnitee in
establishing its claim for indemnity.

     10.4. INSURANCE.  SC shall maintain appropriate product liability
insurance with respect to  development, manufacture and sales of the Products
by SC in such amount as SC customarily maintains with respect to sales of its
other products.  SC shall maintain such insurance for so long as it continues
to manufacture or sell the Products, and thereafter for so long as SC maintains
insurance for itself covering such manufacture or sales.


                    ARTICLE 11.  EXPIRATION AND TERMINATION

     11.1. Expiration.
           ----------
   
           11.1.1. TERM OF RESEARCH COLLABORATION.  Unless this Agreement is
sooner terminated in accordance with the provisions of this Article 11, the term
of the Research Collaboration shall expire thirty (30) months from the Funding
Commencement Date; provided, however, that SC may, in its discretion, elect to
extend the Research Collaboration for an additional eighteen (18) months.  SC
shall deliver written notice to GTC at least *          *       prior to the
expiration of the initial term of the Research Collaboration definitively
stating whether SC intends to exercise its option to extend the term of the

                     ARTICLE 12.  PROVISIONS FOR INSOLVENCY

     12.1. GENERAL.  All rights and licenses granted under or pursuant to
this Agreement by GTC to SC are, for all purposes of Section 365(n) of Title 11
of the U.S. Code ("Title 11"), licenses of rights to intellectual property as
defined in Title 11.  GTC agrees during the term of this Agreement to maintain
and preserve any current copies of all such intellectual property which are in
existence and in its possession as of the commencement of a case under Title 11
by or against GTC.  If a case is commenced by or against GTC under Title 11,
then, unless and until this Agreement is rejected as provided in Title 11, GTC
(in any capacity, including debtor-in-possession) and its successors and
assigns (including, without limitation, a Title 11 Trustee) shall, as SC may
elect in a written request, immediately upon such request (A) (i) perform all
of the obligations provided in this Agreement to be performed by GTC, or (ii)
provide to SC copies of all such intellectual property (including all
embodiments thereof) held by GTC and such successors and assigns as of the
commencement of a case under Title 11 by or against GTC and from time to time
thereafter, and (B) not interfere with the rights of SC as provided in this
Agreement, or any agreement supplementary hereto, to such intellectual property
(including all such embodiments thereof), including any right of SC to obtain
such intellectual property (or such embodiment) from any other entity.

     12.2. REJECTION OF AGREEMENT IN TITLE 11.  If a Title 11 case is
commenced by or against GTC and this Agreement is rejected as provided in Title
11 and SC elects to retain its rights hereunder as provided in Title 11, then
GTC (in any capacity, including debtor-in-possession) and its successors and
assigns (including, without limitation, a Title 11 Trustee shall provide to SC
copies of all such intellectual property (including all embodiments thereof)
held by GTC and such successors and assigns immediately upon SC's written
request therefor.  Whenever GTC or any of its successors or assigns provides 
to SC any of the intellectual property licensed hereunder (or any embodiment
thereof) pursuant to this Article 12, SC shall have the right to perform the 
obligations of GTC hereunder with respect


                                      -29-
<PAGE>   35

to such intellectual property, but neither such provision nor such performance
by SC shall release GTC from any such obligation or liability for failing to
perform it; provided, however, that in such event SC shall not be entitled to
compel specific performance by GTC under this Agreement except to the extent of
enforcing the exclusivity of the license granted hereunder.

     12.3. ADDITIONAL RIGHTS.  All rights, powers, remedies, obligations
and conditions of SC provided herein are in addition to and not in substitution
for any and all other rights, powers, remedies, obligations and conditions of
GTC or SC now or hereafter existing at law or in equity (including, without
limitation, Title 11) in the event of the commencement of a Title 11 case by or
against GTC.  SC, in addition to the rights, power and remedies expressly
provided herein, shall be subject to all obligations and conditions, and 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, Title 11) in such event.  The parties agree
that they intend the foregoing rights and obligations of SC to apply to the
maximum extent permitted by law, including without limitation for purposes of
Title 11, (i) the right of access to any intellectual property (including all
embodiments thereof) of GTC, or any third party with whom GTC contracts to
perform an obligation of GTC under this Agreement, and in, the case of the
third party, which is necessary for the development, registration and
manufacture of a Product, and (ii) the right to contract directly with any
third party described in clause (i) in this sentence to complete the contracted
work.


                           ARTICLE 13.  MISCELLANEOUS

     13.1. FORCE MAJEURE.  Neither party shall be held liable or
responsible to the other party nor be deemed to have defaulted under or
breached this Agreement for failure or delay in fulfilling or performing any
term of this Agreement when such failure or delay is caused by or results from
causes beyond the reasonable control of the affected party, including but not
limited to fire, floods, embargoes, war, acts of war (whether war is declared
or not), insurrections, riots, civil commotions, strikes, lockouts or other
labor disturbances, acts of God or acts, omissions or delays in acting by any
governmental authority or the other party; provided, however, that the party so
affected shall use reasonable commercial efforts to avoid or remove such causes
of nonperformance, and shall continue performance hereunder with reasonable
dispatch whenever such causes are removed.  Either party shall provide the
other party with prompt written notice of any delay or failure to perform that
occurs by reason of force majeure.  The parties shall mutually seek a
resolution of the delay or the failure to perform as noted above.

     13.2. ASSIGNMENT.  This Agreement may not be assigned or otherwise
transferred by either party without the consent of the other party; provided,
however, that either GTC or SC may, without such consent, assign its rights and
obligations under this Agreement (i) to any Affiliate, all or substantially all
of the equity interest of which is owned and controlled by such party or its
direct or indirect parent corporation, or (ii) in connection with a merger,
consolidation or sale of substantially all of such party's assets to an
unrelated Third Party; provided, however, that such party's rights and
obligations under this Agreement shall be assumed by its successor in interest
in any such transaction and shall not be transferred


                                     -30-
<PAGE>   36

separate from all or substantially all of its other business assets, including  
those business assets that are the subject of this Agreement.  Any purported
assignment in violation of the preceding sentence shall be void.  Any permitted
assignee shall assume all obligations of its assignor under this Agreement.

     13.3. SEVERABILITY.  Each party hereby agrees that it does not intend
to violate any public policy, statutory or common laws, rules, regulations,
treaty or decision of any government agency or executive body thereof of any
country or community or association of countries.  Should one or more
provisions of this Agreement be or become invalid, the parties hereto shall
substitute, by mutual consent, valid provisions for such invalid provisions
which valid provisions in their economic effect are sufficiently similar to the
invalid provisions that it can be reasonably assumed that the parties would
have entered into this Agreement with such valid provisions.  In case such
valid provisions cannot be agreed upon, the invalidity of one or several
provisions of this Agreement shall not affect the validity of this Agreement as
a whole, unless the invalid provisions are of such essential importance to this
Agreement that it is to be reasonably assumed that the parties would not have
entered into this Agreement without the invalid provisions.

                          ---------------------------


This MATERIAL TRANSFER AGREEMENT, including the attached Schedules,
(collectively the "Agreement") is entered into as of the last date on the
signature page hereof (the "Effective Date") by and between the Schering-Plough
Research Institute, a Delaware corporation with its office and place of
business at 2015 Galloping Hill Road, Kenilworth, New Jersey 07033, (the
"SUPPLIER"), and the organization identified on the signature page (the
"RECIPIENT").

1.   BACKGROUND.  SUPPLIER has developed and produced certain
     Material (as defined below).  RECIPIENT is conducting certain

     conditions set forth in this Agreement.

2.   Definitions.
     -----------

     2.1  "CONFIDENTIAL INFORMATION" includes, without limitation any
          scientific, technical, trade or business information given to one
          party (the "Receiving Party") by the other party (the "Disclosing
          Party") which is treated by the Disclosing Party as confidential or

     (e)  which is required by law, regulation, statute, rule, act or order of
          any governmental authority or agency to be disclosed by Receiving
          Party.

          To permit Disclosing Party an opportunity to intervene, in order to
          obtain a protective order or other similar order to limit or prevent
          disclosures of Confidential Information, Receiving Party shall
          immediately notify Disclosing Party, in writing, if it is requested
          by a court order, a governmental agency, or any other entity to
          disclose Confidential Information in Receiving Party's possession and
          thereafter Receiving Party shall disclose only the minimum

<PAGE>   45

          under state, federal, or foreign patent, trademark, copyright or
          similar laws) that incorporate the Material, or that could not have
          been developed without the use of the Material, or that require the
          use of the Material, that are discovered, developed, created,
          conceived or reduced to practice by the RECIPIENT, alone or jointly
          with others, during the term of this Agreement.  Developments
          include, without limitation, New Substances and New Uses.

     2.3  "MATERIAL" means the material to be transferred from SUPPLIER to
          RECIPIENT, as described in Schedule A attached to this Agreement,
          together with any refills of the Material and any progeny and
          unmodified derivatives of the Material (including, without
          limitation, expression products, subclones, sub-units or
          fractionations).

     2.4  "NEW SUBSTANCE" means any material first produced or isolated with or
          by use of the Material.

     written permission of SUPPLIER.

4.   Acknowledgment.
     --------------

     4.1  RECIPIENT acknowledges that the Material is experimental in nature
          and may have hazardous properties.  RECIPIENT agrees to comply with
          all laws and regulations applicable to its handling.

     4.2  RECIPIENT acknowledges and agrees that the Material is or may be the
          subject of a patent or patent application.  Except as expressly
          provided in this Agreement, no licenses or other rights, either
          expressed or implied, are provided to the RECIPIENT under any
          patents, patent applications, trade secrets or other proprietary
          rights of the SUPPLIER.  In particular, no express or implied
          licenses or other rights are provided to use the Material,
          Modifications, Developments, or any related patent or patent
          applications of SUPPLIER for any Commercial Purposes.

5.   NO WARRANTY.  THE MATERIAL IS PROVIDED BY SUPPLIER TO RECIPIENT WITHOUT 
     ANY WARRANTY, EXPRESS OR IMPLIED, INCLUDING ANY WARRANTY OF
     MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, AND SUPPLIER MAKES NO
     REPRESENTATION THAT RECIPIENT'S USE OF THE MATERIAL WILL NOT INFRINGE ANY
     PATENT OR OTHER PROPRIETARY RIGHTS OF ANY THIRD PARTY.  THE MATERIAL IS
     PROVIDED TO RECIPIENT WITH THE UNDERSTANDING THAT SUPPLIER AND ITS AGENTS,
     EMPLOYEES AND AFFILIATES, HAVE NO LIABILITY WHATSOEVER IN CONNECTION WITH
     SUCH MATERIAL OR ITS USE.

6.   INDEMNIFICATION.  Except to the extent prohibited by law,

     from any claims and liabilities which might arise from RECIPIENT's use of
     the Material, except for those arising from the gross negligence or

7.   Ownership and Grant of Rights.
     -----------------------------

     7.1  MATERIAL.  SUPPLIER has developed the Material over a substantial
          period of time at considerable expense, and the Material is of great
          importance to SUPPLIER's business.  RECIPIENT acknowledges that
          SUPPLIER is and will at all times remain the owner of the Material.

     7.2  OWNERSHIP OF DEVELOPMENTS.  RECIPIENT acknowledges and agrees that
          all rights, title and interest in and to any and all Developments
          resulting from RECIPIENT's use of the Materials provided hereunder
          will belong solely to SUPPLIER, and RECIPIENT will take all steps
          necessary to enable SUPPLIER to perfect its rights to all such
          Developments.

     7.3  DISCLOSURE OF DEVELOPMENTS.  RECIPIENT will promptly and fully
          disclose in writing to SUPPLIER any and all Developments.  RECIPIENT
          will keep complete and accurate written records of its Research.  At
          SUPPLIER's request, RECIPIENT will meet with SUPPLIER to discuss the
          Research.  In addition, RECIPIENT will provide SUPPLIER with periodic
          written summaries of its Research.  RECIPIENT acknowledges and agrees
          that data transmitted to SUPPLIER cannot be considered as
          confidential.

     7.4  PATENT APPLICATIONS.  Any patent applications considered necessary in
          the reasonable legal and business judgment of SUPPLIER to protect
          SUPPLIER's proprietary position in any Developments will be prepared
          and filed by SUPPLIER (jointly in SUPPLIER's and RECIPIENT's names,
          if jointly invented; solely in SUPPLIER's or RECIPIENT's name, if
          solely invented) with the expenses of these patent applications being
          born by SUPPLIER.  At SUPPLIER's request and expense, RECIPIENT will
          cause its interest in any Developments to be assigned to SUPPLIER and
          will provide SUPPLIER with reasonable assistance in preparing such
          applications, including causing the execution of any assignments or
          other documents.

8.   Confidentiality
     ---------------

     8.1  NONDISCLOSURE OF CONFIDENTIAL INFORMATION.  Except as provided in
          Section 9 below, neither party will directly or indirectly publish,
          disseminate or otherwise disclose, deliver or make available to any
          third party any of the other party's Confidential Information other
          than in furtherance of this Agreement.

     8.2  PROTECTION.  RECIPIENT will exercise all commercially reasonable
          precautions to protect the integrity and confidentiality of the
          Material.  RECIPIENT will not remove the Material from RECIPIENT's
          premises except to the extent necessary to fulfill its obligations
          under this Agreement, and then only with the prior written consent of
          SUPPLIER.

9.   Publication.
     -----------

     9.1  RIGHT TO PUBLISH; REVIEW BY SUPPLIER.  Notwithstanding RECIPIENT's
          confidentiality obligations under Section 8 above, RECIPIENT will
          have the right to publish and disclose the final results of the
          Research.  In order to balance this right with SUPPLIER's proprietary
          interests, RECIPIENT will submit for SUPPLIER's review all
          manuscripts, abstracts or presentations intended for publication or
          other public disclosure ("Publications") at least sixty (60) days
          prior to the date of submission for publication or public disclosure.
          SUPPLIER will use reasonable efforts to complete its review promptly
          and will complete its review within sixty (60) days of receipt of the
          Publications.  No Publication shall contain any Confidential
          Information of SUPPLIER.  At SUPPLIER's request RECIPIENT shall
          delete from its Publications any references deemed by SUPPLIER to be
          Confidential Information.  At the end of this sixty (60) day period,
          RECIPIENT will have the right to publish the Publications, as amended
          by SUPPLIER and subject to SUPPLIER's rights under Section 9.2 below.

     9.2  OPPORTUNITY TO FILE PATENT APPLICATIONS.  If during its sixty (60)
          day Publication review period SUPPLIER notifies RECIPIENT that it
          desires patent applications to be filed on any developments disclosed
          or contained in the Publications, RECIPIENT will defer publication or
          other disclosure for a period sufficient to permit SUPPLIER to file
          any such patent applications, such period not to exceed ninety (90)
          days from the date of submission of the Publication to SUPPLER.

          current Research as defined in Section 2.6.

     10.2 TERMINATION FOR CAUSE.  Either party may terminate this Agreement for
          cause at any time upon thirty (30) days prior written notice to the
          other party.  "Cause" means a material breach of this Agreement by
          the other party where such breach, if curable, is not remedied to the
          nonbreaching party's satisfaction within such thirty (30) day period.

     10.3 TERMINATION BY EITHER PARTY WITHOUT CAUSE.  Either party may
          terminate this Agreement at any time without cause upon not less than
          sixty (60) days prior written notice to the other party.

     10.4 EFFECT OF TERMINATION OR EXPIRATION.  Upon termination or expiration
          of this Agreement for any reason RECIPIENT shall immediately return
          to SUPPLIER all its Confidential Information and copies thereof, and
          shall return, or at SUPPLIER's direction to destroy, any and all
          unused Material, and if instructed to destroy such Material will
          provide evidence documenting the manner of destruction to SUPPLIER. 
          All of RECIPIENT's rights to use the



                                     - 5 -
<PAGE>   49

          Material shall cease.  Following termination or expiration, neither
          party shall have any further obligations under this Agreement, except

          survive and remain in force.

11.  NOTICE.  All communications and notices from one party to
     the other will be in writing and will be given by addressing the same to
     the other party at the address or facsimile number set forth in this

     writing signed by both parties.

15.  SEVERABILITY.  In the event that any one or more of the
     provisions in this Agreement shall, for any reason, be held to be invalid,
     illegal or unenforceable in any respect, such invalidity, illegality or
     unenforceability shall not affect any other provisions of this Agreement,
