            NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 March 31, 1997
                                   (unaudited)

1.  Summary of Significant Accounting Policies
    Basis of Presentation


The information contained herein has been prepared in accordance with
instructions for Form 10-Q and Article 10 of Regulation S-X. The information at
March 31, 1997, and for the three months ended March 31, 1997 and 1996, is
unaudited. In the opinion of management, the information reflects all
adjustments necessary to make the results of operations for the interim periods
a fair statement of such operations. All such adjustments are of a normal
recurring nature. Interim results are not necessarily indicative of results for
a full year. For a presentation including all disclosures required by generally
accepted accounting principles, these financial statements should be read in
conjunction with the audited financial statements included in the Company's
Annual Report to Shareholders for the year ended December 31, 1996.

   Per Share Data

Net loss per share is computed using the weighted average number of shares
outstanding during the periods.

In February 1997, the Financial Accounting Standards Board issued Statement No.
128, Earnings per Share, which is required to be adopted on December 31, 1997.
At that time the Company will be required to change the method currently used to
compute earnings per share and to restate all prior periods. Under the new
requirements for calculating primary earnings per share, the dilutive effect of
stock options will be excluded. The impact of Statement 128 on the calculation
of primary earnings per share for the quarters presented is not expected to be
material.

   Consolidation

The consolidated financial statements include the accounts of the Company and
its wholly owned subsidiary, Amylin Europe Limited. All significant intercompany
transactions and balances have been eliminated.


2.  Contingency

The Company has received letters from the University of Minnesota (the
"University") asserting that pramlintide is covered by a patent (the "University
Patent") which was licensed to the Company pursuant to a License Agreement dated
November 11, 1991 
<PAGE>   7
among the Company, the University and Per Westermark ("Westermark") (the
"University License Agreement"). In its letters, the University claims that they
and Westermark are entitled to 50% of any sublicense fees received by the
Company from sublicensing the University Patent to Johnson & Johnson pursuant to
the Company's Collaboration Agreement with Johnson & Johnson, as well as future
royalties as specified in the University License Agreement. The Company has
informed the University and Westermark that no such sublicensing moneys have
been received by the Company from Johnson & Johnson, who is not a sublicensee
under the University Patent. On December 5, 1996, the Company filed a complaint
against the University and Westermark in the U.S. District Court for the
Southern District of California seeking a declaratory judgment that pramlintide
is not covered by the University Patent and that no moneys are owed to the
University or Westermark. Although discussions were underway with the University
and Westermark, they did not result in any agreement regarding the litigation.
The Company's complaint was served on the University and Westermark in April
1997. The Company believes the University's assertions are without merit and
intends to defend vigorously against any claims that may be brought by the
University against the Company related to the foregoing.




<PAGE>   8
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

         Except for the historical information contained herein, the discussion
in this report contains forward-looking statements that involve risks and
uncertainties. The Company's actual results could differ materially from those
discussed in this report. Factors that could cause or contribute to such
differences include, without limitation, those discussed in the section entitled
"Liquidity and Capital Resources" herein as well as those discussed in the
Company's Annual Report on Form 10-K for the year ended December 31, 1996 under
the heading "Risk Factors."

         Since its inception in September 1987, Amylin Pharmaceuticals, Inc.
("Amylin Pharmaceuticals" or the "Company") has devoted substantially all of its
resources to its research and development programs. Substantially all of the
Company's revenues to date have been derived from fees and expense
reimbursements under collaborative agreements and from interest income. Amylin
Pharmaceuticals has not received any revenues from the sale of products. The
Company has been unprofitable since its inception and expects to incur
additional operating losses for the next several years. As of March 31, 1997,
the Company's accumulated deficit was approximately $161.8 million.


RESULTS OF OPERATIONS

Revenue

         The Company had $12.4 million of revenue for the three month period
ended March 31, 1997 as compared to $3.3 million for the same period in 1996.
The revenues recognized in 1997 and 1996 were related to the Company's
Collaboration Agreement with LifeScan, Inc., a wholly owned subsidiary of
Johnson & Johnson, hereinafter referred to as Johnson & Johnson. Revenues in
1997 were comprised of Johnson & Johnson's one-half share of collaboration
development expenses incurred by Amylin in the first quarter and $6.0 million in
license fee payments made by Johnson & Johnson related to the exercise of their
option to broaden the scope of the collaboration with the Company to include all
amylin agonists for the treatment of fuel metabolism disorders, including
diabetes. Revenues in 1996 were comprised of Johnson & Johnson's one-half share
of collaboration development expenses incurred by Amylin in the first quarter of
1996. (Please see the "Liquidity and Capital Resources" section for further
discussion of payments expected to be received by the Company in the future.)

Operating Expenses

         The Company's total operating expenses for the quarter ended March 31,
1997 increased to $19.4 million from $10.5 million for the same period in 1996.

         Research and development expenses increased to $16.5 million for the
three months ended March 31, 1997 as compared to $8.6 
<PAGE>   9
million for the same period in 1996. The increase in these expenditures was
primarily due to the costs of expanding pramlintide clinical development
efforts. Several other factors also contributed to this increase, including
increased staffing and expanded product development efforts.

         General and administrative expenses increased to $2.8 million for the
three months ended March 31, 1997 as compared to $1.9 million for the same
period in 1996. The increase was primarily related to expanded pramlintide
market development efforts in connection with the Company's collaboration with
Johnson & Johnson.

Other Income and Expense

         Interest and other income is principally comprised of interest income
from investment of the Company's cash reserves. Interest and other income was
$0.7 million for the quarter ended March 31, 1997 as compared to $0.6 million
for the same period in 1996.

         Interest and other expense is principally comprised of interest expense
resulting from long-term debt obligations. Debt financing has been utilized by
the Company to acquire laboratory and other equipment and to fund tenant
improvements to the Company's facilities. In addition, in accordance with the
terms of the Company's Collaboration Agreement with Johnson & Johnson, Johnson &
Johnson has advanced Amylin's share of pramlintide pre-launch marketing expenses
incurred since the date of the collaboration, to be repaid with interest over
time out of Amylin's share of future pramlintide profits if any. Interest and
other expense increased to $0.3 million for the three months ended March 31,
1997 from $0.1 million for the same period in 1996. The increase in interest and
other expense reflects the overall higher long-term debt balance during the
first three months of 1997 as compared to 1996 as well as a provision of
approximately 0.1 million made for the disposal of certain pieces of equipment.

Net Loss

         The net loss for the quarter ended March 31, 1997 was $6.6 million
compared to a net loss for the first quarter of 1996 of $6.6 million. Although
the net loss remained virtually unchanged between the years, operating expenses
did increase significantly in 1997 as compared to 1996, but they were partially
offset by the $6.0 million license fee payment received in the quarter along
with payments received for Johnson & Johnson's one-half share of collaboration
development expenses incurred by Amylin. The increase in operating expenses for
the quarter was primarily the result of expanded clinical, product development
and pre-marketing activities on pramlintide.

         Amylin expects to incur substantial operating losses over the next
several years due to continuing and increasing expenses associated with its
research and development programs, including preclinical and potential clinical
testing of multiple product candidates, and related general and administrative
support. 
<PAGE>   10
Operating losses may fluctuate from quarter to quarter as a result of
differences in the timing of expenses incurred and revenues recognized.


LIQUIDITY AND CAPITAL RESOURCES

         Since its inception, the Company has financed its operations primarily
through private placements of preferred stock, sales of common stock, its
collaboration with Johnson & Johnson, and operating and capital lease
obligations.

         In June 1995, the Company entered into a worldwide Collaboration
Agreement with Johnson & Johnson for the development and commercialization of
pramlintide, a diabetes drug candidate currently in Phase III clinical trials.
In conjunction with the Collaboration Agreement, the Company also entered into a
Stock Purchase Agreement with Johnson & Johnson Development Corporation (a
wholly owned subsidiary of Johnson & Johnson referred to herein as Johnson &
Johnson) and a Loan Agreement with Johnson & Johnson.

                  In March 1997, Johnson & Johnson exercised an option to
broaden the scope of the existing collaboration on pramlintide and paid the
Company $6.0 million to obtain additional rights for all amylin agonists for
treatment or prevention of fuel metabolism disorders, including diabetes. The
Company will lead the research and development while Johnson & Johnson will lead
commercialization of any future product candidates.

         In addition to the above mentioned milestone-related payments and
investment, Johnson & Johnson's financial commitment to the Company now includes
the funding of 50% of development costs and 100% of pre-launch marketing costs
(Amylin Pharmaceutical's one-half share to be repaid over time from future
profits), as well as milestone payments, license fees, equity investments, and a
development loan facility for use in certain circumstances. The Company will
apply all of the license fees, any cash milestone payments, 50% of the proceeds
from Johnson & Johnson's equity investments and proceeds from draw downs under
the development loan facility towards its share of pramlintide development
expenses.

         Funding available to the Company from Johnson & Johnson as of March 31,
1997 under the development loan facility (the "Development Loan Facility") was
$57.1 million. The aggregate amount of the Development Loan Facility is subject
to adjustment for certain events, e.g. increased by 50% of any increases in the
pramlintide development budget as of December 31, 1996 and decreased by 50% of
the Company's net proceeds received from future debt or equity offerings to
investors other than Johnson & Johnson or other corporate partners. The Company
is required to issue a warrant to Johnson & Johnson to purchase 50,000 shares of
the Company's common stock at an exercise price of $12.00 per share for every $1
million of proceeds borrowed by the Company under the Development Loan Facility.
Under the terms of the Loan Agreement, the Company is eligible in certain
circumstances to make quarterly draw downs on the then available Development
Loan Facility based on 
<PAGE>   11
pramlintide development expenses during specified periods. The projected
aggregate amount available to be borrowed by the Company under the Development
Loan Facility during 1997 is $42.3 million, which is subject to adjustment based
on changes to the pramlintide development budget and on certain corporate
financing activities. As of March 31, 1997 the Company has not drawn down any
proceeds available to it under the Development Loan Facility.

         The Company is dependent on the future payments from Johnson & Johnson
to continue development and commercialization of pramlintide. Johnson & Johnson
may terminate the Collaboration Agreement subject to a notice period of six
months. Johnson & Johnson's financial and other obligations under the
Collaboration Agreement would continue during any such termination notice
period. In addition, Johnson & Johnson has the right to terminate the
Collaboration Agreement at any time based on material safety or tolerability
issues. Without Johnson & Johnson's continued collaborative support, the Company
might not be able to continue the pramlintide development program, and the
Company's financial condition would be materially adversely affected.

         As of March 31, 1997, Johnson & Johnson entities have made various
financial payments to the Company totaling approximately $109 million. These
payments primarily include funding of one half of the pramlintide development
costs, the purchase of $30 million of the Company's common stock, milestone and
option fee payments and license fees.

         At March 31, 1997, the Company had $59.6 million in cash, cash
equivalents and short-term investments as compared to $62.1 million at December
31, 1996. The Company invests its cash in U.S. government and other highly rated
liquid debt instruments.

         The Company intends to use its financial resources for the ongoing
development of pramlintide, including the Phase III efficacy studies, for
expansion of its other research, drug discovery and development programs, and
for other general corporate purposes. To the extent that clinical trials of the
Company's compounds progress as planned, research and development expenses will
include costs of supplying materials for and conducting pramlintide clinical
trials, research activities to further explore amylin biology, and research and
development of other compounds targeted at metabolic diseases. The amounts
actually expended for each purpose may vary significantly depending upon
numerous factors, including the progress of the Company's research and
development programs, the results of preclinical and clinical studies, the
timing of regulatory submissions and approvals, if any, technological advances,
determinations as to commercial potential of the Company's compounds, and the
status of competitive products. Expenditures will also depend upon the continued
participation of Johnson & Johnson in the collaboration, the availability of
additional sources of funds, the establishment of collaborative arrangements
with other companies, and other factors.

         The Company currently leases or sub-leases approximately 99,000 square
feet of space. At this time, the Company expects to 
<PAGE>   12
incur approximately $5.9 million of capital expenditures in 1997. These
expenditures will primarily be directed toward the purchase of new equipment to
support research and development efforts and for tenant improvements for newly
sub-leased space. In addition, some capital expenditures will be directed toward
the purchase of equipment coming off of lease lines which will expire during the
year. The Company has entered into a loan agreement for the financing of the
majority of its equipment needs and intends to use this financing source during
1997. The Company anticipates that it will utilize approximately $3.4 million of
debt financing and $2.5 million of its own cash reserves for capital
expenditures in 1997. The terms of the Company's loan agreement call for amounts
drawn down under the loan to be repaid monthly over a four year period.

         The Company does not expect to generate a positive internal cash flow
for several years due to substantial additional research and development costs,
including costs related to drug discovery, preclinical testing, clinical trials,
manufacturing costs, and general and administrative expenses necessary to
support such activities. In addition to the 1997 and 1998 funding of 50% of the
six pivotal studies and other ancillary studies in the pramlintide clinical
program, the Company plans to expand its research and development pipeline by
licensing new technologies and product candidates. The Company anticipates that
its existing cash, including interest income from cash investments, and
financial payments and loan facilities from Johnson & Johnson, will be adequate
to satisfy the Company's capital requirements through 1998. As an alternative to
the additional funding available through the Johnson & Johnson Development Loan
Facility (as described above), the Company may also consider additional equity
offerings. Assuming continued participation by Johnson & Johnson, the Company
believes it has reasonable alternatives to meet the financial needs of its
programs. However, there can be no assurance that additional financial resources
will be raised in the necessary time frame or on terms favorable to the Company.

         The Company cannot assure that any of its drug candidates will
successfully meet all of their development goals. Important technical milestones
remain to be achieved before Amylin Pharmaceuticals can commercialize any of its
products, and failure to achieve these milestones could seriously jeopardize the
Company's chances of success and its financial condition would be adversely
affected. The Company's future capital requirements will depend on many factors,
including continued scientific progress in its research and development
programs, the magnitude of these programs, progress with preclinical and
clinical trials, the time and costs involved in preparing regulatory submissions
and seeking regulatory approvals, the costs involved in preparing, filing,
prosecuting, maintaining, and enforcing patents, competing technological and
market developments, changes in the Johnson & Johnson collaboration, the ability
of the Company to establish collaborative arrangements for its other research
and development programs, and the cost of manufacturing scale-up.

         Prior to marketing, any drug developed by the Company must undergo
rigorous preclinical and clinical testing and an 
<PAGE>   13
extensive regulatory approval process mandated by the Food and Drug
Administration (FDA) and equivalent foreign authorities. Human clinical testing
is now underway on the Company's first product candidate, pramlintide. Subject
to compliance with FDA regulations, the Company plans to undertake extensive
clinical testing to demonstrate optimal dose, safety, and efficacy for its
product candidates in humans. Although preliminary clinical data about
pramlintide's possible clinical value warrants continuing Phase III trials,
there can be no assurance that these larger and longer studies will confirm the
results of the Phase I and Phase II studies to date. Further testing of
pramlintide and the Company's other product candidates in research or
development may reveal undesirable and unintended side effects or other
characteristics that may prevent or limit their commercial use. The Company or
the FDA may suspend clinical trials at any time if the subjects or patients
participating in such trials are being exposed to unacceptable health risks.
There can be no assurance that the Company will not encounter problems in
clinical trials which will cause the Company or the FDA to delay or suspend
clinical trials. In addition, there can be no assurance that any of the
Company's products will obtain FDA approval for any indication. Products, if
any, resulting from Amylin Pharmaceuticals' research and development programs
are not expected to be commercially available for a number of years.

                  The Company believes that patent and other proprietary rights
are important to its business, and in this regard intends to file applications
as appropriate for patents covering both its products and processes. Litigation,
which could result in substantial cost to the Company, may also be necessary to
enforce any patents issued to the Company or to determine the scope and validity
of third-party proprietary rights. The Company has received letters from the
University of Minnesota (the "University") asserting that pramlintide is covered
by a patent (the "University Patent") which was licensed to the Company pursuant
to a License Agreement dated November 11, 1991 among the Company, the University
and Per Westermark ("Westermark") (the "University License Agreement"). In its
letters, the University claims that they and Westermark are entitled to 50% of
any sublicense fees received by the Company from sublicensing the University
Patent to Johnson & Johnson pursuant to the Company's Collaboration Agreement
with Johnson & Johnson, as well as future royalties as specified in the
University License Agreement. The Company has informed the University and
Westermark that no such sublicensing moneys have been received by the Company
from Johnson & Johnson, who is not a sublicensee under the University Patent. On
December 5, 1996, the Company filed a complaint against the University and
Westermark in the U.S. District Court for the Southern District of California
seeking a declaratory judgment that pramlintide is not covered by the University
Patent and that no moneys are owed to the University or Westermark. Although
discussions were underway with the University and Westermark, they did not
result in any agreement regarding the litigation. The Company's complaint was
served on the University and Westermark in April 1997. The Company believes the
University's assertions are without merit and intends to defend 
<PAGE>   14
vigorously against any claims that may be brought by the University against the
Company related to the foregoing. In addition, should any of the Company's
competitors have prepared and filed patent applications in the United States
which claim technology also invented by the Company, Amylin Pharmaceuticals may
have to participate in interference proceedings declared by the U.S. Patent and
Trademark Office in order to determine priority of invention and, thus, the
right to a patent for the technology, all of which could result in substantial
cost to the Company to determine its rights. It is uncertain whether any
third-party patents will require the Company to alter its products or processes,
obtain licenses, or cease certain activities. If any licenses are required,
there can be no assurances that the Company will be able to obtain any such
license on commercially favorable terms, if at all. Failure by the Company to
obtain a license to any technology that it may require to commercialize its
products may have a material adverse impact on the Company.


Material Agreement

         In March 1997, the Company entered into a Technology License Agreement
(the "License Agreement") with Hoechst Marion Roussel, pursuant to which the
Company was granted exclusive worldwide rights to a series of orally active
compounds which will be evaluated for their ability to improve cardiovascular
risk factors associated with the development of atherosclerosis.

         Under the terms of the License Agreement, the Company is responsible
for conducting the preclinical evaluation and clinical development of candidate
compounds. Upon completion of Phase II clinical trials, Hoechst Marion Roussel
will have a one-time right to elect to collaborate with the Company in the
continuing development and commercialization of these compounds in a 50:50
cost-and-profit sharing arrangement. If Hoechst Marion Roussel exercises this
option, the Company will continue to be responsible for developing and
registering the product candidates, and Hoechst Marion Roussel will be
responsible for manufacturing and marketing. The Company and Hoechst Marion
Roussel will assume equal responsibility for all past and future research and
development, manufacturing, and commercialization expenses and will share
equally in any operating profits from commercialization. If Hoechst Marion
Roussel does not exercise its option, the Company will retain all development
and commercialization rights, and Hoechst Marion Roussel will be entitled to a
royalty based on any future net sales. In such case, the Company will be free to
collaborate with other companies on the development, manufacture, and
commercialization of these compounds.

ITEM 1. LEGAL PROCEEDINGS

         The Company has received letters from the University of Minnesota (the
"University") asserting that pramlintide is covered by a patent (the "University
Patent") which was licensed to the Company pursuant to a License Agreement dated
November 11, 1991 among the Company, the University and Per Westermark
("Westermark") (the "University License Agreement"). In its letters, the
University claims that they and Westermark are entitled to 50% of any sublicense
fees received by the Company from sublicensing the University Patent to Johnson
& Johnson pursuant to the Company's Collaboration Agreement with Johnson &
Johnson, as well as future royalties as specified in the University License
Agreement. The Company has informed the University and Westermark that no such
sublicensing moneys have been received by the Company from Johnson & Johnson,
who is not a sublicensee under the University Patent. On December 5, 1996, the
Company filed a complaint against the University and Westermark in the U.S.
District Court for the Southern District of California seeking a declaratory
judgment that pramlintide is not covered by the University Patent and that no
moneys are owed to the University or Westermark. Although discussions were
underway with the University and Westermark, they did not result in any
agreement regarding the litigation. The Company's complaint was served on the
University and Westermark in April 1997. The Company believes the University's
assertions are without merit and intends to defend vigorously against any claims
that may be brought by the University against the Company related to the
foregoing.

and expenses hereunder with respect to the Products using its standard
accounting procedures, consistent with United States Generally Accepted
Accounting Principles, to the extent practical, as if such Products were solely
owned products of the Party. The Parties also recognize that such procedures may
change from time to time and that any such changes may affect the definition of
Net Sales, Royalty-Bearing Sales, Allowable Expenses, Research and Development
Expenses, Pre-Marketing Expenses and such other costs and expenses. The Parties
agree that, where such changes are economically material to either Party,
adjustments shall be made to compensate the affected Party in order to preserve
the same economics as reflected under this Agreement under such Party's
accounting procedures in effect as of the date on which the activity in question
(for example, Research, Development, marketing or manufacturing) first commences
under this Agreement. Where the change is or would be economically material to
one Party, the other Party shall provide an explanation of the proposed change
and an accounting of the effect of the change on the relevant revenue, cost or
expense category. For purposes of this Section 3.11, "economically material"
shall mean, before the first commercial launch of a Collaboration Product, a
change which affects Research Expenses, Research and Development Expenses and/or
Pre-Marketing Expenses by five percent

                                      -13-

(5%) or more, and after the first commercial launch of a Collaboration Product,
a change which affects Operating Profits or Losses by five percent (5%) or more.



                                   ARTICLE IV

                         JOINT RESEARCH AND DEVELOPMENT

        4.1     RESPONSIBILITIES OF THE JDC.

                (a)     Following the Effective Date, the JDC shall oversee the
Research and Development of Collaboration Compounds in order to obtain
Regulatory Approvals, as set forth in this Article IV. The JDC will also (i)
oversee the preparation of Research and Development Plans and Research and
Development Budgets and submit such plans and budgets to the Steering Committee
for review and budget approval, (ii) evaluate and designate Collaboration
Compounds for Research and Development and (iii) facilitate the flow of
Information with respect to Research and Development being conducted for each
Collaboration Product. In addition, in connection with an approved
Commercialization Budget and/or an approved Launch Budget, the JDC will oversee

IV Clinical Trials as may be reasonably requested by the JCC.

                (b)     Decisions of the JDC shall be approved by a majority
vote of the members of the JDC. If the JDC is unable to obtain a majority
affirmative vote as to any matter involving Research or Development, except for
(i) increasing the Research and Development Budget (other than as provided for
in the Initial Research and Development Plan and Budget in Section 4.4(a)), (ii)
altering the Research and Development Plan in a manner which would (1) change
indications for which a Collaboration Product is being developed, (2) conduct
Development for less than North America and the European Union or (3) change or
add a route of delivery or line extension of a Collaboration Product in
Development or (iii) terminating a Phase III Clinical Trial prior to completion
in accordance with its protocol (collectively, the "Excepted Development
Matters"), the decision of Amylin will be final and determinative so long as
such decision does not contradict or modify the terms of this Agreement. Such
Excepted Development Matters shall be referred to the Steering Committee for
consideration pursuant to Section 3.4 of this Agreement.

                (c)     The JDC will have the power to form subcommittees with
appropriate representation from Amylin, HMR and appropriate Third Parties;
provided, however, that any Third Party member of a subcommittee must be
approved by HMR.

                (d)     During clinical trials for any Collaboration Products,
the JDC and JCC shall work together to assure a smooth transition from
Development of such Collaboration Products to Commercialization of such
Collaboration Products, including, without limitation,


                                      -14-
<PAGE>   21

product claims, product positioning, pre-launch medical education and
communications programs. In addition, the JDC shall keep the JCC informed of
proposed changes in the dosage form of Collaboration Products and the countries
in which Phase III Clinical Trials are being conducted.

        4.2     LEAD RESEARCH AND DEVELOPMENT PARTY. Amylin will be the lead
Research and Development Party with respect to all Collaboration Products and,
as a result, shall be obligated and responsible for carrying out Research and
Development pursuant to each Research and Development Plan. Amylin will commence
reporting to the JDC within sixty (60) days following the Effective Date. Amylin
will report to the JDC at such times and in such manner as is reasonably
determined by the JDC from time to time. HMR agrees to carry out such Research
and Development tasks as are reasonably requested by Amylin and accepted by HMR.
In addition, consideration shall be given to HMR to participate in other
Research and Development activities, as mutually agreed upon by the Parties. All
HMR Research and Development Expenses will be included in Research and
Development Expenses to the account of HMR .

        4.3     RIGHT TO ENGAGE THIRD PARTIES. In the course of its business,
Amylin regularly uses Third Parties to perform certain Research and Development
activities. Amylin will continue to do so during the course of this Agreement,
and expenses relating to such Third Party Development will be included in
Amylin's Research and Development Expenses.

        4.4     RESEARCH AND DEVELOPMENT PLAN AND RESEARCH AND DEVELOPMENT
BUDGET.

                (a)     The Research and Development of each Collaboration
Product shall be governed by a Research and Development Plan and a Research and
Development Budget, which shall provide for Development in at least all Core
Dossier Countries and, together with updates, shall be prepared by Amylin, after
taking into consideration HMR's comments, for budget approval by the Steering
Committee. The Parties shall agree upon and approve an Initial Research and
Development Plan and Budget within sixty (60) days after the Effective Date. If
the Parties are unable to agree on the Initial Research and Development Plan and
Budget within such sixty (60) day period, then the Initial Research and
Development Plan and Budget shall be referred to the Steering Committee for
resolution by the Steering Committee.

                (b)     Each Research and Development Plan shall describe the
proposed overall program of Research and Development for the subject
Collaboration Product in each applicable country, including preclinical studies,
toxicology, formulation, process development, clinical studies and regulatory
plans and other elements of obtaining Regulatory Approval in each applicable
country. HMR shall provide such guidance as Amylin reasonably requests regarding
local Drug Approval Application submission requirements. The Research and
Development Plan shall include a summary of estimated Research and Development
Expenses of the program expected during the Research and Development process
through obtaining Regulatory Approval 

                                      -15-
<PAGE>   22

for each proposed indication and route of delivery, and shall also include a
detailed Research and Development Budget for all Research and Development
activities proposed for the following twelve (12) months.

                (c)     Each Research and Development Plan and Research and
Development Budget shall be updated annually by Amylin, after taking into
account HMR's comments, and shall be submitted by October 1 of each calendar
year to the Steering Committee for review and for Research and Development
Budget approval. The Steering Committee shall provide comments on each such
updated Research and Development Plan and Research and Development Budget within
thirty (30) days following its receipt of such plan and budget. Within ninety
(90) days following its receipt of such plan and budget, the Steering Committee
shall either approve the Research and Development Budget submitted by the JDC or
approve a modified Research and Development Budget prepared by the Steering
Committee consistent with the objectives for the Collaboration Products and the
aims of the collaboration contemplated by this Agreement. If the Steering
Committee fails to approve any budget increase in the Research and Development
Budget or a material change of the type described in Section 4.1(b)(ii) in the
Research and Development Plan, the Research and Development Budget and the
Research and Development Plan shall remain at its previously approved level or
previous unmodified form.

        4.5     DEVELOPMENT EFFORTS. Each Party agrees to exert the efforts
necessary and reasonable to execute and substantially carry out the Research and
Development Plan within the Research and Development Budget and to cooperate
with the other Party in carrying out the Research and Development Plan.

        4.6     DRUG APPROVAL APPLICATIONS. Consistent with the Research and
Development Plan, Amylin shall be responsible for preparing and filing all
filings with the regulatory authorities with respect to HMR Compounds in each
country in the Profit Sharing Territory ("Regulatory Filings"), including, but
not limited to, Drug Approval Applications, and seeking Regulatory Approvals for
Collaboration Products in the Profit Sharing Territory, including preparation of
all reports necessary as part of a Drug Approval Application. All such Drug
Approval Applications shall be filed jointly in the names of Amylin and HMR if
permitted by the regulatory agency. If a joint filing is not permitted,
simultaneous filings of identical Drug Approval Applications, one in Amylin's
name and one in HMR's name, shall be made ("Simultaneous Filings"). If neither
of the preceding filing scenarios is permitted by a regulatory agency, the Drug
Approval Application in such case shall be filed in the name of Amylin, and a
copy of such Drug Approval Application shall be simultaneously provided to HMR
together with written notice from the regulatory agency that neither joint
filings nor Simultaneous Filings are permitted in such jurisdiction. Amylin
shall be responsible for prosecuting all such Drug Approval Applications,
including any such Drug Approval Applications filed in HMR's name. In the event
a Drug Approval Application is filed in the name of a single Party, the other
Party shall have the right of cross reference. The Parties shall consult and
cooperate in the preparation of each Drug Approval Application and in obtaining
Regulatory Approvals. Upon receipt of 

                                      -16-
<PAGE>   23

each Regulatory Approval, Amylin shall promptly transfer ownership of the
corresponding Drug Approval Application and Regulatory Approval to HMR, provided
HMR is the marketing Party in the country wherein Regulatory Approval is
obtained, and shall promptly notify the appropriate regulatory agency of such
transfer of ownership. Transfer of sole ownership shall occur earlier in time if
necessary for negotiating pricing approvals pursuant to Section 5.11. In the
event HMR's right to market any Collaboration Products under this Agreement
terminates for any reason, HMR shall promptly transfer any and all of its
ownership rights in the corresponding Drug Approval Application and Regulatory
Approvals to Amylin. In connection with all Drug Approval Applications being
prosecuted by Amylin hereunder, each Party agrees to provide the other Party
with a copy (which may be wholly or partly in electronic form) of all filings to
regulatory agencies it makes on its behalf or on the other Party's behalf
hereunder.

        4.7     COSTS OF DEVELOPMENT.

                (a)     All Research and Development Expenses of Collaboration
Products under this Agreement shall be shared equally by the Parties.

                (b)     HMR shall advance to Amylin, on the next to last
business day of each calendar quarter ending subsequent to the Effective Date,
HMR's share of the budgeted Research and Development Expenses for the following
quarter, based on the most recently approved Research and Development Budget.

                (c)     Each Party shall maintain records of Research and
Development Expenses incurred by it in accordance with procedures to be agreed
upon between the Parties. Subsequent to the Effective Date, Amylin and HMR shall
report quarterly to each other on their Research and Development Expenses, with
such reports to be submitted within twenty (20) days after the end of each
calendar quarter and within thirty (30) days after the end of each calendar
year. The Parties shall seek to resolve any questions related to such accounting
reports within sixty (60) days following receipt of such reports. If the Parties
are unable to resolve any disputes regarding such accounting reports within such
sixty (60) day period, such dispute will be referred to the Steering Committee
for resolution pursuant to Section 3.4.

                (d)     Any differences between the actual expenses incurred in
a particular quarter and the budgeted expenses for such quarter upon which HMR's
advance payment was made to Amylin shall be applied as an adjustment to the
following quarter's payment due from HMR as follows:

                        (i)     in the event actual expenses exceed budgeted
        expenses for a particular quarter, the amount of the difference shall be
        added to the amount due under HMR's next quarterly advance payment of
        budgeted Research and Development Expenses; and 

                                      -17-
<PAGE>   24

                        (ii)    in the event actual expenses are less than
        budgeted expenses for a particular quarter, the amount of the difference
        shall be subtracted from the amount due under HMR's next quarterly
        advance payment of budgeted Research and Development Expenses.

                (e)     Notwithstanding the provisions of Section 4.7(d), Amylin
shall be solely responsible for any Research and Development Expenses exceeding,
during a calendar year, one hundred five percent (105%) of the most recently
approved Research and Development Budget for such year, and such overage, if
any, shall be paid by Amylin to HMR within ten (10) days after the amount of
such overage is determined, unless the overage is (i) the result of actions of
HMR (in which case HMR shall bear the expense), (ii) is approved by the Steering
Committee or (iii) is the result of the requirements of regulatory authorities
(in which cases the Parties shall share the expense equally). If actual costs
and expenses for a given calendar year are less than or equal to 5% below
budgeted costs and expenses for such year, then such amount will be carried
forward into the next calendar year's budget. If actual costs and expenses for a
given calendar year are more than 5% below budgeted costs and expenses for such
year, then the Parties will mutually determine the portion of such amount in
excess of 5%, if any, that will be carried forward into the next calendar year's
budget.

        4.8     ELECTION BY A PARTY TO TERMINATE ITS PARTICIPATION IN THE
DEVELOPMENT OF A COLLABORATION COMPOUND OR COLLABORATION PRODUCT FOR SAFETY OR
TOLERABILITY REASONS.

                (a)     In the event material issues regarding the Safety or
Tolerability of a Collaboration Compound or Collaboration Product arise during
the Development thereof, each Party shall have the right to terminate its
participation in worldwide Development of such Collaboration Compound or
Collaboration Product as provided below in Section 4.8(b). A Party's decision to
terminate its participation in Development of a particular Collaboration
Compound or Collaboration Product shall be in its own discretion.

                (b)     In the event one Party's participation in Development of
a Collaboration Compound or Collaboration Product is terminated pursuant to this
Section 4.8, then (i) such termination shall be effective thirty (30) days
following the date of receipt of written notice by the non-terminating Party of
the terminating Party's decision to terminate its participation, (ii) the
terminating Party shall not be responsible for any Research and Development
Expenses related to such Collaboration Compound or Collaboration Product after
the date the termination is effective, (iii) the non-terminating Party may
thereafter proceed independently with research, development and/or
commercialization of the 

                                      -18-
<PAGE>   25

compound or product in question as an Independent Product, either alone or in
conjunction with Third Parties and (iv) the terminating Party shall, to the
extent not previously granted under this Agreement or the License Agreement, (1)
grant exclusive licenses (even as to the granting Party) under Amylin Patents or
HMR Patents, as applicable, Joint Patents and know-how Controlled by such Party
to the non-terminating Party for continued research, development and/or
commercialization of the compound or product in question, (2) shall transfer any
related Drug Approval Applications or Regulatory Approvals (including transfer
of all relevant data and information relevant to Regulatory Authorities) to the
non-terminating party, and (3) otherwise cooperate to enable the non-terminating
Party under this Section 4.8 to continue said research, development and/or
commercialization. In the event a termination of participation in Development of
a Collaboration Compound or Collaboration Product occurs under this Section 4.8,
such Independent Product shall thereafter bear a royalty of ******************
of Royalty-Bearing Sales on a country-by-country basis for the later to occur of
(i) ten (10) years from the first commercial sale of such Independent Product in
such country and (ii) the expiration of the last to expire of any issued patents
covering such Independent Product in any relevant country; provided, however,
that such Collaboration Compound or Collaboration Product may not be so
independently developed or commercialized for any indication for which a
Collaboration Product or Royalty-Bearing Product is being (i) Developed, (ii)
Commercialized, or (iii) Developed and/or Commercialized, in all cases in at
least two Major Market Countries at the time the termination under this Section
4.8(b) became effective for any Collaboration Compound or Collaboration Product.
Royalty payments, if any, due under this Section 4.8(b) shall be paid in
accordance with the provisions of Section 6.6.

                (c)     The rights set forth in this Section 4.8 to terminate
participation in Development of a particular Collaboration Compound or
Collaboration Product for Safety or Tolerability reasons shall be separate from,
and in addition to, the right to terminate this Agreement pursuant to Article
XII.

        4.9     INSURANCE. Throughout the Research and Development of a
Collaboration Product, Amylin agrees to have in place comprehensive general
liability insurance, including, but not limited to, product liability insurance
(which shall include coverage for clinical trials) of at least **********
combined single limit with an aggregate limit of at least **********, which
insurance shall include HMR as an additional insured. Amylin agrees to provide
HMR with thirty (30) days prior written notice in the event it elects to
voluntarily terminate such insurance. When insurance is obtained as required
under this Section 4.9, Amylin agrees to provide HMR with a certificate of
insurance evidencing its retention of such insurance coverage and any updates
thereto.

such to the Steering Committee pursuant to Section 8.1, and (viii) facilitate
the flow of Information with respect to the Commercialization of each
Collaboration Product. Subject to the provisions of Section 5.1(b) regarding
Excepted Commercialization Matters, HMR shall make the final decision on all
matters relating to the Commercialization of any Collaboration Product,
including all day to day decisions.

                (b)     Decisions of the JCC shall require a majority vote of
all members of the JCC. If the JCC is unable to obtain a majority affirmative
vote as to any matter involving Commercialization, the decision of HMR will be
final and determinative, so long as such decision does not contradict or modify
the terms of this Agreement, except with regard to (i) a decision to recall a
Collaboration Product, which shall be decided pursuant to Section 5.12, (ii) a
dispute related to pricing of a Collaboration Product, which shall be referred
to the executive officers of the Parties pursuant to Section 5.11, (iii) a
dispute related to manufacturing of a Collaboration Product, which shall be
referred to the executive officers of the Parties pursuant to Article XII of the
License Agreement, or (iv) a Third Party promotion support arrangement for a
Collaboration Product which also involves the promotion support of a
non-Collaboration Product(s), which must be approved by the Steering Committee
pursuant to Section 5.3(a) (collectively, the "Excepted Commercialization
Matters").

                (c)     The JCC will have the power to form subcommittees with
appropriate representation from Amylin, HMR and appropriate Third Parties;
provided, however, that any Third Party members of such a subcommittee must be
approved by Amylin.

                (d)     During clinical trials for any Collaboration Products,
the JCC shall coordinate with the JDC to assure a smooth transition from
Development to Commercialization.

                (e)     The JCC shall not be involved with the commercialization
of (i) Independent Products or (ii) Royalty-Bearing Products in any
Royalty-Bearing Countries.

        5.2     HMR AS LEAD MARKETING PARTY.

                (a)     HMR will be the lead marketing party with respect to all
Collaboration Products and, as a result, shall be obligated and responsible for
carrying out Commercialization pursuant to each Commercialization Plan. HMR will
assemble its product team and commence 


                                      -20-
<PAGE>   27

reporting to the JCC within sixty (60) days following the Effective Date. Amylin
agrees to carry out the Commercialization tasks referred to in Section 5.2(b)
and such other Commercialization tasks as are reasonably requested by HMR and
accepted by Amylin.

                (b)     It is recognized that the Parties bring particular
strengths to the ongoing Commercialization of Collaboration Products. HMR will
assign to Amylin a role in Commercialization functions and activities, both
during Development and following Collaboration Product launch, as follows:

                        (i)     it is anticipated by the Parties that from the
        Effective Date throughout the marketing of Collaboration Products,
        Amylin will provide members for the HMR product teams, participating in
        the development of all strategies and performing activities relating to
        the following marketing functions as part of the Commercialization Plans
        and Launch Plans in the Core Dossier Countries:

                             -       Medical Symposia
                             -       Scientific Exhibits
                             -       Opinion Leader Program Development
                             -       Medical Education Program Development;

                        (ii)    furthermore, in preparation for, but at least
        twelve (12) months prior to, product launch of the first Collaboration
        Product hereunder in the first Core Dossier Country, Amylin will provide
        a small (not to exceed one hundred (100) persons) dedicated field force
        of experienced, scientifically competent "Medical Liaison Officers"; and

                        (iii)   Amylin's activities will be performed in
        accordance with each approved Commercialization Plan and
        Commercialization Budget and each approved Launch Plan and Launch
        Budget. All other marketing activities that have not been assigned to
        Amylin will be the responsibility of HMR, unless determined otherwise by
        the JCC.

        5.3     RIGHT TO ENGAGE THIRD PARTIES.

                (a)     If HMR determines that it needs promotion support in the
Profit Sharing Territory and Amylin does not provide it, or HMR determines
Amylin is not reasonably capable of providing it, then HMR may contract for
additional promotion support from a Third Party. In such event, the Parties will
consult prior to the engagement of a Third Party. The costs of engaging such
Third Party will be a Royalty Expense (as defined in Exhibit A). Any other use
of a Third Party, such as the sublicensing of a Third Party with respect to
co-marketing and/or co-promotion in the Profit Sharing Territory, must be
approved by the Steering Committee as described in Section 3.4, except to the
extent such arrangements either directly or indirectly also 


                                      -21-
<PAGE>   28

involve the marketing, promotion, co-marketing and/or co-promotion of
non-Collaboration Products. To the extent any non-cash consideration is conveyed
to either Party as part of any arrangement under this Section 5.3, the other
Party shall be made whole.

                (b)     In the event that HMR decides not to market a
Collaboration Product in a country, the Parties will consider whether it is
desirable to license a Third Party to market in such country, and only if both
Parties so agree, the Parties, through HMR with full participation by Amylin,
shall attempt to license such rights to a Third Party. Royalties received under
this provision, if any, shall be included in Net Sublicense Revenues.

        5.4     COMMERCIALIZATION EFFORTS. Each Party agrees to exert the
efforts necessary and reasonable to execute and substantially carry out the
Commercialization Plans and Launch Plans within the Commercialization Budgets
and Launch Budgets and to cooperate with each other in carrying out the
Commercialization Plans. In addition, with regard to the determination of all
pricing, sampling and discount strategies for Collaboration Products, HMR shall
use a similar and no less rigorous approach as that used by it in determining
such strategies for its own pharmaceutical products of comparable market
potential.

        5.5     COMMERCIALIZATION PLAN AND COMMERCIALIZATION BUDGET.

                (a)     HMR shall develop a commercialization plan (the
"Commercialization Plan") for each Collaboration Product, which shall include
but not be limited to (i) global demographics and market dynamics, Major Market
Country market strategies, estimated country launch dates, a worldwide sales and
expense forecast (including at least three (3) years of estimated sales and
expenses), manufacturing plans and expected product profile based upon the
Research and Development Plan, (ii) a market plan (including pricing strategies
pertaining to discounts, samples and Nominal Price sales) for the United States,
which will serve as a strategic reference for other market plans for countries
such as Germany, the United Kingdom, France and Japan (it being understood that
such market plans will evolve over time and shall be similar to existing market
plans developed at such time by HMR for pharmaceutical products with comparable
market potential), and (iii) a commercialization budget ("Commercialization
Budget") for each Collaboration Product for all applicable countries so
determined by HMR (but at a minimum, the countries covered by the then current
Research and Development Plan), including the Third Parties to be utilized and
the arrangements with them that have been or are proposed to be agreed upon.
Each Commercialization Budget shall include a budget of the expenses expected to
be incurred in connection with performing the Commercialization Plan, including
Pre-Marketing Expenses and Allowable Expenses in each applicable country.

                (b)     The first Commercialization Plan shall be in the form of
an initial outline and the first Commercialization Budget shall be in the form
of an estimated budget. The JCC shall submit such outline of the first
Commercialization Plan and such estimated Commercialization Budget to the
Steering Committee for review and approval no later than six 


                                      -22-
<PAGE>   29

(6) months following the Effective Date. It is understood that such outline and
estimate may contain open issues and identify areas wherein more information is
needed to complete the outline and estimated budget and to prepare a more
complete Commercialization Plan and Commercialization Budget. Thereafter, by
October 1 of each subsequent year, HMR, after taking into consideration Amylin's
comments, will prepare a Commercialization Plan for submission by the JCC to the
Steering Committee for review and a Commercialization Budget for submission by
the JCC to the Steering Committee for review and approval. Notwithstanding
anything in this Agreement to the contrary, the Commercialization Budget shall
be approved by the Steering Committee no later than October 31 of each year. For
any subsequent Collaboration Products, HMR shall prepare and the JCC shall
submit an outline of an initial Commercialization Plan for each such
Collaboration Product to the Steering Committee for review and an estimated
Commercialization Budget for review and approval no later than six (6) months
after any Collaboration Compound is designated a Collaboration Product. Each
such Commercialization Plan and Commercialization Budget shall be updated and
refined on each subsequent October 1 as described above in connection with
Collaboration Compounds. Any significant change in any Commercialization Plan or
Commercialization Budget during the course of the year will be communicated
promptly to the JCC. In addition, HMR shall provide an update of each
Commercialization Plan and Commercialization Budget to the JCC in a manner
consistent (with respect to timing and content) with such updates as are
reported internally by HMR on its existing pharmaceutical products of comparable
market potential.

        5.6     LAUNCH PLAN.

                (a)     Each Commercialization Plan shall be updated, in advance
of the launch of the applicable Collaboration Product in each country as the JCC
determines is appropriate, to include a Launch Plan and Launch Budget for such
launch and the twelve (12) month period following the launch date for such
Collaboration Product. Each such Launch Plan and Launch Budget shall be
developed by HMR, after taking into consideration Amylin's comments, and
presented to the JCC for Launch Plan and Launch Budget review and approval and
to the Steering Committee for Launch Budget approval, with HMR having the final
decision at the JCC and Steering Committee as described in Section 3.4. The
Steering Committee shall have sixty (60) days to review and approve such Launch
Budget. If the Steering Committee is unable to approve the Launch Budget within
such sixty (60) day period, the Launch Budget shall be submitted to the Parties'
executives as provided for in Article XII of the License Agreement.

                (b)     It is understood by the Parties that determining a date
for Regulatory Approval and thus a launch date is difficult. The failure to
accurately estimate the launch date shall not constitute a breach hereunder. As
a result of this uncertainty, the JDC shall estimate for each country a
realistic date for Regulatory Approval, and the JCC will use this estimated date
to submit its Launch Plan and Launch Budget at least twelve (12) months prior to
the estimated Regulatory Approval date, to the Steering Committee. By October 1
of each calendar year thereafter, if not yet executed, each Launch Plan and
Launch Budget for each Collaboration 

                                      -23-

Product shall be updated by HMR and the updated Launch Budget shall be submitted
by the JCC for approval by the Steering Committee.

                (c)     Each Launch Plan shall include (i) updated market and
sales forecasts in units and estimated revenues of Collaboration Product, (ii)
estimated resource requirements and (iii) such other matters deemed appropriate
by HMR.

                (d)     Each Launch Budget shall include a breakdown of
individual Allowable Expense items expected to be incurred in connection with
performing the applicable Launch Plan. It is understood that there will not
necessarily be a separate Launch Plan and Launch Budget for each country in
which a Collaboration Product launch is planned, but that estimated launch
dates, Launch Budgets and Launch Plans for each country in which a launch is
planned may be incorporated into one or more comprehensive Launch Plans and
Launch Budgets.

        5.7     ELECTION BY AMYLIN OF ROYALTY-BEARING COUNTRIES.

                (a)     With respect to all countries other than the Core
Dossier Countries, within sixty (60) days after the Steering Committee approves
a Launch Budget for each Collaboration Product, Amylin may make a one-time,
irrevocable election on a country-by-country basis to withdraw from
expense-sharing with respect to such Collaboration Product in the applicable
country, in which case such country shall become a Royalty-Bearing Country and
Amylin shall receive a royalty of ****************** on Royalty-Bearing Sales in
such Royalty-Bearing Country with respect to such Royalty-Bearing Product, in
accordance with Section 6.4(a) and Section 6.4(b). Amylin's election to withdraw
with respect to a Collaboration Product pursuant to this Section 5.7(a) shall be
effective thirty (30) days after receipt by HMR of written notice from Amylin of
its election to withdraw, which written notice shall specify the Collaboration
Product and the country(ies) subject to such withdrawal. Withdrawal under this
Section 5.7(a) by Amylin shall relieve it from its obligation to carry out and
complete the Research and Development Plan as it relates to countries from which
it withdraws hereunder.

                (b)     Subject to Sections 7.3, 11.2 and 11.3, the
Commercialization of Royalty- Bearing Products shall be conducted independently
by HMR.

        5.8     ADVERTISING AND EDUCATION. HMR, after consultation with the JCC,
will assign to the Parties, their Affiliates or any Third Party the preparation
of advertising and education materials. Such materials shall be subject to prior
review and comment by Amylin and HMR, which review and comment by Amylin and HMR
shall be completed within thirty (30) days after receipt of such materials by
Amylin and HMR. With respect to written and visual promotional or educational
materials, to the extent such materials identify or otherwise make reference to
either of the Parties, Amylin and HMR shall both be presented and described with
equal prominence, as permitted by the applicable laws and regulations of each
country in which such materials are to be presented. All product labeling,
documentary information, promotional

material and oral presentations (where practical) regarding the detailing and
promoting of Collaboration Products shall display the names and logos of Amylin
and HMR with equal prominence. All advertising and education and training
materials for use in a country must also be approved in advance by the Party
holding the relevant Drug Approval Application or responsible for the Regulatory
Approval for such country, as necessary to ensure such Party's compliance with
all applicable Regulatory Approvals. Such approval or disapproval shall be given
by the Party within thirty (30) days after receipt of such advertising and
education and training materials.

        5.9     PRE-MARKETING EXPENSES. Amylin and HMR shall share equally in
Pre-Marketing Expenses; provided, however, that HMR will fund all Pre-Marketing
Expenses for the first Collaboration Product. Amylin's 50% share of such
Pre-Marketing Expenses for the first Collaboration Product shall be reimbursed
by Amylin to HMR from its share of Operating Profits as provided in Section
6.2(b). In this regard, a written accounting of Pre-Marketing Expenses incurred
by Amylin within a Commercialization Plan and Budget shall be submitted by
Amylin to HMR within twenty (20) days of the end of each calendar quarter and
within thirty (30) days of the end of each calendar year in which such expenses
were incurred. HMR will repay Amylin within thirty (30) days of its receipt of
such written accounting. Notwithstanding anything in this Agreement to the
contrary, in the event that greater than 50% of the voting stock or
substantially all of the assets of Amylin are acquired by (i) an entity with a
market capitalization equal to or in excess of $2.5 billion in publicly traded
stock or (ii) a privately held entity with annual sales in excess of $1 billion,
then HMR's obligation to fund all Pre-Marketing expenses for the first
Collaboration Product pursuant to this Section 5.9 shall terminate and be of no
further effect.

        5.10    TRAINING PROGRAM. HMR will develop adequate training programs
for personnel involved in the Commercialization of Collaboration Products and/or
Royalty-Bearing Products. Amylin shall play an appropriate role, as determined
by the JCC, in the preparation of such training materials and conduct of
training; provided, however, that Amylin shall not be involved in the
preparation of training materials or the conduct of training with respect to
Royalty-Bearing Products in a Royalty-Bearing Country or HMR's Independent
Products. HMR shall submit to Amylin for its review all training materials,
which review shall be completed within thirty (30) days of receipt of such
materials by Amylin. The Parties agree to utilize such training programs on an
ongoing basis to assure a consistent, focused promotional strategy. Training
shall be carried out at a time which is determined by HMR, and which is prior to
but reasonably near the date on which Regulatory Approval is expected. The costs
of transporting, housing and maintaining personnel to be trained, and the
preparation of materials, shall be deemed to be Pre-Marketing Expenses or
Marketing Expenses, as the case may be.

        5.11    PRICING, PRICING APPROVALS AND PRODUCT DISTRIBUTION. If Amylin
does not agree with the recommended price proposed by HMR with respect to a
Collaboration Product, it may, within ninety (90) days following receipt of such
recommended price from HMR, prepare 

                                      -25-
<PAGE>   32

its own analysis of the market potential and recommended price for such
Collaboration Product and present such analysis and recommendation to the
Steering Committee. If the Steering Committee is unable to agree on the prices
for such Collaboration Product within sixty (60) days after receipt of the HMR,
and, if applicable, Amylin pricing recommendations, whichever is later, the
analyses and recommendations of both Parties will be referred to a joint
executive review panel composed of the Chief Executive Officer of Amylin and
HMR's Chief Operating Officer. If this joint executive review panel is unable to
agree on a price after reviewing the submissions from Amylin and HMR within
thirty (30) days following receipt of such recommendations, then HMR shall set
the applicable prices, which shall be somewhere between the prices proposed by
each Party. The above described mechanism shall be the sole method for resolving
disputes as to price(s) and shall not be subject to dispute resolution pursuant
to Article XII of the License Agreement. HMR shall obtain for Collaboration
Products such pricing approvals as may be required by, and arrange for
distribution of each Collaboration Product in, each applicable country of the
Profit Sharing Territory.

        5.12    PRODUCT RECALLS. As an exception to the general authority of HMR
under this Article V, if HMR commences an internal product quality
investigation, it shall promptly notify and consult with Amylin regarding such
investigation. Further, if either Party believes that a recall of a
Collaboration Product is necessary, such Party shall notify and consult with the
other Party within two (2) working days of its determination, and both Parties
shall cooperate to allow such recall to occur under the direction of the
Steering Committee. In the event of a dispute about whether to recall a
Collaboration Product, such recall shall occur.

        5.13    TAX CONSIDERATION. Either Party may take advantage of tax
considerations which benefit it and not the other Party. In the event that a
Party takes advantage of a tax consideration which benefits it and not the other
Party, no compensation to the other Party is required unless such affects the
other Party's Operating Profits or Losses negatively, in which case compensation
shall be provided to the other Party to make it whole. To the extent such
negative impact on one Party's Operating Profits or Losses results from the
manufacture of a Collaboration Product, such impact shall be addressed in the
manner described in Section 8.1.

        5.14    DISCOUNTED SALES. It is possible that Collaboration Products
could be included as part of a multiple product offering to customers by HMR,
and, at times, discounts may be offered independently. In the event that any
Collaboration Products are offered along with other HMR products, the effect of
the potential discounts may not impact the Average Net Selling Price below ****
of the Ex-Manufacturer Selling Price in any given country. In the event that
planned or executed discounting activities related to any Collaboration Product
(pursuant to which such Collaboration Product is sold by HMR in combination with
one or more non-Collaboration Products in any given country) as measured on a
quarterly basis will reduce the Average Net Selling Price below **** of the
Ex-Manufacturer Selling Price in any given country, HMR shall present an
analysis of such discounting forecasts and activities to the JCC for review and
comment. Such analysis will include all appropriate information for such
Collaboration Product

reasonably available to HMR, such as discounts given or forecasted, profit
and/or loss analysis of discounting activities, Average Net Selling Price of
planned or granted discounts for major customers (to be defined by HMR) and a
price versus volume analysis. If the Average Net Selling Price discount with
respect to such Collaboration Products exceeds ***, HMR shall make Amylin whole
with respect to Net Sales of such Collaboration Product (whole equals *** of the
Ex-Manufacturer Selling Price). All sales of such Collaboration Product at a
Nominal Price as well as all sales involving governmental mandated or conceded
discounts are exempt from the Average Net Selling Price calculations. If Amylin
determines that the discounting activities as presented by HMR unfairly
disadvantage Amylin's interest, Amylin may prepare an analysis and present it to
the Steering Committee for review and concurrence. In the absence of agreement
at the Steering Committee, HMR shall have the final determination in this
matter. If market dynamics change (for example, if a directly competing product
were to enter the market, and it were to become in the best interest of both
Parties to discount more than *** below Ex-Manufacturer Selling Price in a
particular country), HMR and Amylin may agree to discount beyond the stated ***
discount to Ex-Manufacturer Selling Price, and in this situation HMR will no
longer be required to keep Amylin whole (whole equals *** of the Ex-Manufacturer
Selling Price). This Section 5.14 regarding "discounted sales? will only be in
effect while any Collaboration Compound is covered by a Patent.


                                   ARTICLE VI

                          PROFIT SHARING AND ROYALTIES

        6.1     SHARE OF OPERATING PROFITS OR LOSSES.

                (a)     Subject to the terms of this Agreement, Amylin and HMR
shall share equally in Operating Profits or Losses.

                (b)     Notwithstanding the foregoing Section 6.1(a) to the
contrary, HMR shall fund Amylin's one-half share of any Operating Losses
incurred during any quarter during the first two years following commercial
launch of a Collaboration Product, which funding by HMR shall be reimbursed by
Amylin pursuant to Section 6.2(b); provided, however, that in the event that
greater than 50% of the voting stock or substantially all of the assets of
Amylin are acquired by (i) an entity with a market capitalization equal to or in
excess of $2.5 billion in publicly traded stock or (ii) a privately held entity
with annual sales in excess of $1 billion, then HMR's obligation to fund
Amylin's one-half share of any Operating Losses pursuant to this Section 6.1(b)
shall terminate and be of no further effect.

        6.2     PAYMENT.

                (a)     Subject to Section 6.2(b), within twenty (20) days of
the end of each of the first three calendar quarters and within thirty (30) days
of the end of the fourth calendar quarter of each year following the launch of
each Collaboration Product in a country, Amylin shall report to HMR and the JCC
as outlined in Exhibit B, its revenues and individual Allowable Expense items
(with appropriate supporting information) involved in the computation of
Operating Profits or Losses and recognized during such quarter with respect to
each such Collaboration Product. Within ten (10) days after receipt of such
report, HMR shall provide for each Collaboration Product one worldwide
consolidated Financial Statement and individual Financial Statements for each
country in the Profit Sharing Territory to the JCC, and the JCC shall promptly
direct the remittance between the Parties of an Equalization Payment with
respect to each Collaboration Product. The reports and Equalization Payments for
the fourth quarter of the fiscal year may include reconciliations and year-end
adjustments with respect to previous quarters. The payment required by this
Section 6.2(a), together with interest accrued from the end of each calendar
quarter (to be paid at the commercial paper rate for high grade unsecured notes
sold through dealers, as quoted in the Wall Street Journal on the last day of
each such quarter), shall be made in any event within thirty (30) days of the
due date of the receipt of reports described in the first sentence of this
Section 6.2(a).

                (b)     Notwithstanding anything to the contrary provided for in
Section 6.2(a), twelve (12) months after the approval of a United States Drug
Approval Application for a Collaboration Product, HMR may withhold from payment
to Amylin an amount equal to ******************* of any Equalization Payment
owed to Amylin pursuant to Section 6.2(a), until such time as HMR has received
from such withheld payments an aggregate amount equal to the sum of (i)
************ (representing ******************* of the remaining ********** of
the agreed upon ************ in costs and expenses incurred by HMR prior to the
effective date of the License Agreement) plus (ii) the aggregate amount of
Amylin's fifty percent (50%) share of Pre-Marketing Expenses for the first
Collaboration Product advanced by HMR pursuant to Section 5.9 plus (iii) the
aggregate amount of Amylin's fifty percent (50%) share of Operating Losses
funded by HMR pursuant to Section 6.1(b).

        6.3     TERM. The Parties shall share Operating Profits or Losses
hereunder with respect to each Collaboration Product in each Profit Sharing
Territory until each such Collaboration Product is permanently withdrawn from
and is no longer being sold anywhere in the relevant Profit-Sharing Territory.

        6.4     ROYALTY-BEARING PRODUCTS.

                (a)     HMR shall pay to Amylin the applicable running royalty,
as set forth in Section 5.7(a), on Royalty-Bearing Sales for Royalty-Bearing
Products, if any.

                (b)     Except as expressly provided in this Agreement, all
royalties to be paid to Amylin on Royalty-Bearing Sales for Royalty-Bearing
Products shall be paid in accordance with the provisions of Section 6.6, on a
country-by-country basis, from the date of the first commercial sale of each
Royalty-Bearing Product in a particular country until the later of (i) ten (10)
years from the first commercial sale in such country or (ii) the last to expire
of any (1) Amylin Patents or (2) HMR Patents or Joint Patents, as applicable,
which covers use or sale of the Royalty-Bearing Product in such country, subject
to the following:

                        (i)     if a generic form of a Royalty-Bearing Product
        is introduced by a Third Party in any country in which neither Amylin
        nor HMR has patent coverage preventing sale or use and such Third Party
        has sales in such country equal to at least ********************* of
        unit sales of the Royalty-Bearing Product in such country, the royalty
        obligation set forth above shall be reduced by ******************* until
        such time, and from time to time, that either Amylin or HMR is granted
        such patent coverage of the Royalty-Bearing Product in such country or
        the generically equivalent product sales in any full calendar quarter
        are reduced to less than ********************* of the Royalty-Bearing
        Product unit sales; and

                        (ii)    the royalty amount to be paid under this
        Agreement with respect to a Royalty-Bearing Product shall be reduced by
        an amount equal to ******************* of any royalties payable to Third
        Parties in respect of the manufacture, use or sale of Royalty-Bearing
        Products.

                Notwithstanding anything in this Section 6.4 to the contrary,
the aggregate reduction of royalties set forth in Subsections (i) and (ii) of
this Section 6.4(b) and in Section 9.4 of this Agreement shall not reduce the
net royalty amount payable under this Section 6.4 by more than
*******************.

                (c)     HMR may discontinue Commercialization of a
Royalty-Bearing Product at any time in its sole discretion.

        6.5     SALES BY SUBLICENSEES. In the event HMR grants licenses or
sublicenses to others to make or sell Royalty-Bearing Products, or in the event
either Party grants licences or sublicenses to others to make or sell
Independent Products, such licenses or sublicenses shall include an obligation
for the licensee or sublicensee to account for and report its Royalty-Bearing
Sales of such Royalty-Bearing Products and/or Independent Products on the same
basis as if such sales were Royalty-Bearing Sales by the Party, and such Party
shall pay royalties to the other Party as if the Royalty-Bearing Sales of the
sublicensee were Royalty-Bearing Sales of the Party granting the license or
sublicense.

        6.6     ROYALTY PAYMENTS AND REPORTS. A report summarizing the
Royalty-Bearing Sales of any Royalty-Bearing Products and/or Independent
Products during the relevant quarter shall be delivered to the receiving Party
within twenty (20) days following the end of each calendar quarter and within
thirty (30) days following the end of each calendar year for which royalties are
due from the selling Party. Royalty payments under this Agreement shall be made
to the receiving Party or its designee quarterly within thirty (30) days
following the due date for the report as set forth in the first sentence of this
Section 6.6.

        6.7     TAXES. The Party receiving royalties shall pay any and all taxes
levied on account of royalties it receives under this Agreement. If laws or
regulations require that taxes be withheld, the Party paying royalties will (i)
deduct those taxes from the remittable royalty, (ii) timely pay the taxes to the
proper taxing authority, and (iii) send proof of payment to the other Party
within thirty (30) days following such payment.

        6.8     BLOCKED CURRENCY. In each country where the local currency is
blocked and cannot be removed from the country, at the election of the selling
Party, royalties or the other Party's share of Operating Profits or Losses
accrued in that country shall be paid to the appropriate Party in the country in
local currency by deposit in a local bank designated by the receiving Party.

        6.9     PAYMENTS TO OR REPORTS BY AFFILIATES. Any payment required under
any provision of this Agreement to be made to either Party or any report
required to be made by any Party shall be made to or by an Affiliate of that
Party if designated by that Party as the appropriate recipient or reporting
entity.

        6.10    NO OVERLAPPING ROYALTIES. Notwithstanding any other provision of
this Agreement to the contrary, in no event shall any royalty payment provided
for under any Section of this Agreement be paid with respect to any sale of an
Independent Product or Royalty-Bearing Product to the extent a royalty payment
has been paid pursuant to any other Section of this Agreement with respect to
such sale; provided, however, that in the event of such overlapping royalty
provisions, the highest royalty rate provided for such sale in this Agreement
shall be the applicable royalty rate for such sale.

with the terms of this Agreement. Such license shall be subject to royalty
payments as provided in Section 4.8.

        7.4     SUBLICENSING. During the term of this Agreement, neither Party
may grant sublicenses of Joint Patents or Patents owned or Controlled by the
other Party except with the express prior written approval of the other Party;

of a Collaboration Product through its usual and customary distributors
performing their usual and customary distribution activities for such Party in
accordance with this Agreement without the other Party's prior written approval
of any necessary sublicenses in connection therewith, and (ii) in the case of

        7.5     THIRD PARTY TECHNOLOGY.

                (a)     The licenses granted under Sections 7.1, 7.2 and 7.3 may
include sublicenses of Third Party technology. Any royalty amounts payable to
Third Parties in connection with sales of Products shall be considered a Royalty
Expense (as defined in Exhibit A) with respect to the sale of Collaboration
Products and in any event shall be offset against any royalty amount owed with
respect to the sale of Royalty-Bearing Products and Independent Products, as
provided under Section 6.4(b)(ii).

                (b)     The licenses granted under Sections 7.1, 7.2 and 7.3, to
the extent they include sublicenses of Third Party technology, shall be subject
to the terms and conditions of the license agreement pursuant to which the
sublicense is granted.

                (c)     During the term of this Agreement, if either Party
becomes aware of technology of a Third Party that would be valuable to the
Development or Commercialization of Collaboration Products, the JDC will
determine whether such technology should be brought into the collaboration
contemplated by this Agreement and the cost of acquiring such technology shall
be borne equally by the Parties. In the event that such acquired technology
results in the payment of Third Party royalties, such royalties shall be a
Royalty Expense with respect to the sale of Collaboration Products, and offset
against any royalty owed with respect to the sale of Royalty-Bearing Products
and Independent Products, as provided under Section 6.4(b)(ii).

                             MANUFACTURE AND SUPPLY

        8.1     MANUFACTURE AND SUPPLY DURING DEVELOPMENT. Amylin will be
responsible for manufacture of Collaboration Products for use during the
Development of Collaboration Products. Payments to Third Party manufacturers for
such manufacture of Collaboration Products and related costs will be included in
Research and Development Expenses for purposes of Article IV. As used in this
Article VIII, "manufacture" shall mean manufacture of Collaboration Products in
bulk form or finished form.

        8.2     MANUFACTURE AND SUPPLY DURING COMMERCIALIZATION. HMR shall be
responsible for arranging for the commercial manufacture of Collaboration
Products in such a manner as to achieve and maintain a substantially competitive
Cost of Goods Sold and to assure quality control and quality assurance as
stringent as such quality control and quality assurance standards used by HMR in
the manufacture of its other pharmaceutical products of comparable market
potential, continuity and security of supply, compliance with cGMP, compliance
with all applicable regulatory requirements, and other terms and conditions of
supply which best serve the interests of the collaboration contemplated by this
Agreement. Such manufacturer(s) may

include either or both of the Parties as well as Third Parties. To enable the
transfer of manufacturing to Amylin in situations under this Agreement where HMR
is obligated to do so, with respect to all contracts entered into by HMR with a
Third Party relating to the manufacture of Collaboration Products, HMR shall use
commercially reasonable efforts to include a provision permitting the assignment
of such contract to Amylin on the same terms for at least three (3) years. In
selecting one or more manufacturers, the goals set forth in the first sentence
of this paragraph shall take precedence over the consideration of whether one
Party or the other then has unused or excess manufacturing capacity. Any
selection of manufacturers for Commercialization shall be subject to the rights
of any Third Parties existing at the time such determination is made.

                (a)     Before selecting a manufacturer for a Collaboration
Product under this Section 8.2, a "make versus buy" analysis and proposed
recommendations shall be presented by HMR to the JCC and then the Steering
Committee for review and approval within sixty (60) days after its receipt of
such recommendation. In addition to the quality control and quality assurance
assessments noted above in this Section 8.2, each such analysis will compare
various potential manufacturers with respect to the following attributes
(collectively, the "Manufacturing Attributes"):  *****************************
******************************************************************************
*************************************************************

                (b)     To the extent the Steering Committee decides that HMR or
Amylin, as the case may be, should manufacture such Collaboration Product and
the "make versus buy" analysis described in Section 8.2(a) shows one or more of
the alternative manufacturers with quality control and quality assurance
standards and Manufacturing Attributes reasonably acceptable to both Parties to
be less expensive, the Steering Committee shall determine whether HMR or Amylin,
as the case may be, should increase the Equalization Payment due to the other
Party or decrease the Equalization Payment due from the other Party, as the case
may be, each quarter by half the amount of such difference to make the other
Party whole.

                (c)     To the extent HMR or Amylin, as the case may be,
manufactures such Collaboration Product pursuant to this Section 8.2, then at
least once every three (3) years, the Party performing the manufacturing shall
present to the JCC a review and analysis of the manufacturing cost elements
identified in Section 8.2(a) to determine if the then current manufacturing
arrangements are substantially competitive with other manufacturing alternatives
at such time. Following such review and analysis, no change will be made to the
Equalization Payment adjustment as described in Section 8.2(b).

        8.3     QUALITY CONTROL, QUALITY ASSURANCE, ETC. During the term of this
Agreement, HMR shall have day to day responsibility for commercial manufacturing
and formulation issues related to product safety and regulatory compliance.
Amylin shall provide technical support reasonably required by HMR or Third
Parties for such manufacture of Collaboration Products.

The costs of providing on-going post-launch technical support shall be an
Allowable Expense under Post-Launch Product R & D Expenses (as defined in
Exhibit A). Regardless of the parties selected to manufacture the Collaboration
Products, each of the Parties shall have rights of inspection and audit as
necessary or reasonable to enable it to comply with its internal quality control
and quality assurance and reporting obligations, including those imposed by
regulatory authorities. In addition, before a final commitment is made to any
Party or Parties or to any Third Party regarding manufacturing plant decisions,
both Parties shall have the right to perform plant quality assurance audits.

        8.4     PROVISIONS FOR THE MANUFACTURE OF COLLABORATION PRODUCTS. If a
Party is manufacturing and supplying the Collaboration Products pursuant to
Section 8.2, such Party shall be entitled to recover as an Allowable Expense
such Party's Cost of Goods Sold for Collaboration Products so supplied, upon the
sale of such Collaboration Products according to its standard accounting
procedures consistently applied within and across its pharmaceutical operating
units for matching revenues with costs of products sold for pharmaceutical
products with a comparable market potential. In the event a Party would obtain a
tax benefit from such manufacture of Collaboration Products in a particular
jurisdiction, such tax benefit shall be treated as described in Section 5.13.

        8.5     TECHNOLOGY TRANSFER IN EVENT OF TERMINATION BY HMR. In the event
that, upon termination by HMR of this Agreement, HMR is manufacturing in whole
or in part one or more Collaboration Products or Royalty-Bearing Products under
this Article VIII, then HMR shall continue to provide for such manufacture of
such Collaboration Products and Royalty-Bearing Products to the extent provided
prior to notice of such termination, from the time notice of such termination is
provided until such time as Amylin is able to secure an equivalent alternative
manufacturing source, in the event that Amylin is unable to secure such an
alternative source during the notice period. To this end, as of the effective
date of such termination, all Third Party manufacturing contracts that are
assignable shall be assigned to Amylin, and the cost charged to Amylin by HMR
for any of the internal manufacturing activities to be continued by HMR pursuant
to this Section 8.5 for the production of Collaboration Products and
Royalty-Bearing Products shall be the same as HMR's cost during the time that
the Agreement was in effect; provided, however, that HMR may receive a profit
for its internal manufacturing activities relating to such Products at a rate of
********************************************************************************
********************************************************************************
Further, upon Amylin's request, HMR shall provide such technical assistance and
know-how licenses on a royalty free basis as may reasonably be requested to
transfer such technology needed by Amylin to commence or continue manufacture of
Collaboration Products and Royalty-Bearing Products.

Such technical assistance shall be provided at HMR's cost, which cost shall be
reimbursed by Amylin within thirty (30) days after receipt of an invoice for
such cost by Amylin.


                                   ARTICLE IX

                    ENFORCEMENT OF INTELLECTUAL PROPERTY AND PATENT RIGHTS

        9.1     GENERAL ENFORCEMENT RIGHTS.

                (a)     With respect to infringement of any of the Amylin
Patents or any of the Joint Patents by a Third Party through the manufacture,
import, use, sale or offer for sale of a product competitive with a
Collaboration Product being Developed or Commercialized under this Agreement,
except as provided in Section 9.5(a) ("Competitive Product Infringement"),
Amylin shall have the right to institute, prosecute and control any action or
proceeding with respect to such infringement (with HMR having the right to
participate in such action and be represented if it so desires by counsel of its
own selection) and, if necessary, HMR agrees to be joined as a party plaintiff
and to give Amylin reasonable assistance and any needed authority to control,
file and prosecute such action. Amylin's and, if any, HMR's costs related to
patent enforcement (including internal costs and expenses specifically
attributable to said patent enforcement) and related recoveries with respect to
Competitive Product Infringement shall be treated as Allowable Expenses and Net
Sublicense Revenues, respectively. With respect to infringement of any of the
HMR Patents by a Third Party through Competitive Product Infringement, HMR shall
have the right to institute, prosecute and control any action or proceeding with
respect to such infringement (with Amylin having the right to participate in
such action and be represented if it so desires by counsel of its own selection)
and, if necessary, Amylin agrees to be joined as a party plaintiff and to give
HMR reasonable assistance and any needed authority to control, file and
prosecute such action. The Parties shall consult with each other regarding the
institution, prosecution and control of any action or proceeding with respect to
any infringement of any of the HMR Patents, other than Competitive Product
Infringement. In the absence of agreement with respect to such infringement,
each Party may proceed in such manner as the law permits. HMR's and, if any,
Amylin's costs related to patent enforcement (including internal costs and
expenses specifically attributable to said patent enforcement) and related
recoveries with respect to Competitive Product Infringement shall be treated as
Allowable Expenses and Net Sublicense Revenues, respectively. In this regard, if
it is believed in good faith that any Amylin Patents, HMR Patents, or Joint
Patents are infringed by a Third Party through the manufacture, import, use,
sale or offer for sale of a product competitive with a Collaboration Product,
the Party first having knowledge of such infringement shall promptly notify the
other Party in writing thereof, which notice shall set forth the facts of such
infringement in reasonable detail. If Amylin or HMR, as the case may be, fails
to institute and prosecute an action or proceeding to abate the infringement
within a period of ninety (90) days after receiving written notice or otherwise
having knowledge of the infringement, then the other 

                                      -35-
<PAGE>   42

Party shall have the right, but not the obligation, to bring and prosecute any
such action and the Party which failed to bring such action agrees to be joined
as a party plaintiff and to give the Party bringing such action reasonable
assistance and all authority to control, file and prosecute the suit as may be
necessary; provided, however, that the Party which failed to bring such action
shall have the right to participate in such action and to be represented in any
such action by counsel of its choice. The Parties' costs of patent enforcement
(including internal costs and expenses specifically attributable to said patent
enforcement) and related recoveries with respect to actions brought under this
paragraph shall be treated as Allowable Expenses and Net Sublicense Revenues,
respectively. Any recovery of damages and costs in such action referred to in
this Section 9.1(a) shall be apportioned between the Parties as follows: (i) the
Party bringing suit shall first recover from any such award an amount equal to
the cost and expense incurred by such Party and (ii) the remainder, if any,
shall be divided equally by the Parties.

        (b)     No settlement or consent judgment or other voluntary final
disposition of suit under this Section 9.1 may be entered into without the joint
consent of Amylin and HMR.

        9.2     DEFENSE AND SETTLEMENT OF THIRD PARTY CLAIMS AGAINST
COLLABORATION PRODUCTS. If a Third Party asserts that a patent or other right
owned by it is infringed by the manufacture, import, use, sale or offer for sale
of any Collaboration Product, the Party first obtaining knowledge of such a
claim shall immediately provide the other Party notice of such claim and the
related facts in reasonable detail. In such event, the Steering Committee shall
determine how best to control the defense of any such claim. In the event the
Parties cannot agree on the defense of any such claim, such defense shall be
controlled by HMR; provided, however that Amylin shall have the right to
participate in such defense and to be represented in any such action by counsel
of its selection at its sole discretion. The entity (whether Amylin and HMR, or
HMR only) that controls the defense of a given claim with respect to a
Collaboration Product, shall also have the right to control settlement of such
claim; provided further, however, that no settlement shall be entered into
without the written consent of the other Party. If there is no agreement between
the Parties as to any proposed settlement, then the dispute shall be decided by
the Steering Committee and if the Steering Committee is unable to decide the
dispute, the matter will be resolved pursuant to the dispute resolution
provisions of Article XII of the License Agreement. If the dispute is not
resolved pursuant to Article XII of the License Agreement, then the case may not
be settled.

        9.3     ALLOCATION OF EXPENSES. The expenses of patent defense,
settlement and judgments pursuant to Section 9.2 with respect to Collaboration
Products shall be a shared expense of the Parties, except as otherwise expressly
provided for in Section 9.2. Such costs which are incurred after the designation
of a Collaboration Product for Development but prior to Regulatory Approval
shall be borne in the same manner as if such costs were Development Expenses.
Such costs which are incurred following launch of the subject Collaboration
Product in a Major Market Country shall be an Allowable Expense, reimbursed to
the Party incurring such expense.

        9.4     SETTLEMENT OF THIRD PARTY CLAIMS FOR ROYALTY-BEARING PRODUCTS
AND INDEPENDENT PRODUCTS; ROYALTY REDUCTION.

                (a)     If a Third Party asserts that a patent or other right
owned by it is infringed by any Royalty-Bearing Product, and as a result of
settlement procedures or litigation under this Section 9.4, HMR is required to
pay the Third Party a royalty or make any payment of any kind for the right to
sell a Royalty-Bearing Product in a particular country, the royalty rate for
such Royalty-Bearing Product shall be adjusted as recited in Section 6.4(b).

                (b)     If a Third Party asserts that a patent or other right
owned by it is infringed by any Independent Product, and as a result of
settlement procedures or litigation under this Section 9.4), either Party is
required to pay the Third Party a royalty or make any payment of any kind for
the right to sell an Independent Product in a particular country, the royalty
rate for such Independent Product shall be adjusted as recited in Section
6.4(b).

        9.5     INFRINGEMENT BY THIRD PARTIES WITH RESPECT TO ROYALTY-BEARING
PRODUCTS OR INDEPENDENT PRODUCTS.

                (a)     If any Amylin Patent is infringed by a Third Party in
any country in connection with the manufacture, import, use, sale or offer for
sale of a product competitive with one or more Royalty-Bearing Products or
Independent Products being marketed by HMR in such country, the Party to this
Agreement first having knowledge of such infringement shall promptly notify the
other in writing. The notice shall set forth the facts of that infringement in
reasonable detail. Amylin shall have the primary right, but not the obligation,
to institute, prosecute, and control any action or proceeding with respect to
such infringement of the Amylin Patent, by counsel of its own choice, and HMR
shall have the right to participate in such action and to be represented by
counsel of its own choice. If Amylin fails to bring an action or proceeding
within a period of ninety (90) days after having knowledge of that infringement,
HMR shall have the right to bring and control any such action by counsel of its
own choice, and Amylin shall have the right to participate in such action and to
be represented by counsel of its own choice. If one Party brings any such action
or proceeding, the second Party agrees to be joined as a party plaintiff and to
give the first Party reasonable assistance and authority to control, file and
prosecute the suit as necessary. The costs and expenses of the Party bringing
suit under this Section 9.5(a) (including the internal costs and expenses
specifically attributable to said suit) shall be reimbursed first out of any
damages or other monetary awards recovered in favor of the Parties. Any
remaining damages shall be split ******************* to Amylin and
******************* to HMR if Amylin institutes and controls such suit. However,
if HMR institutes and controls such suit, any damage recovery shall be treated
as Royalty-Bearing Sales and Amylin shall receive a portion of such damages
equal to the applicable royalty rate (expressed as a percentage) payable to
Amylin on said Royalty-Bearing Sales and all remaining damages shall be
distributed to HMR.

                (b)     If any HMR Patent or Joint Patent is infringed by a
Third Party in any country in connection with the manufacture, import, use, sale
or offer for sale of a product competitive with one or more Royalty-Bearing
Products being marketed by HMR, or with one or more Independent Products being
marketed by Amylin in such country, the Party to this Agreement first having
knowledge of such infringement shall promptly notify the other in writing. The
notice shall set forth the facts of that infringement in reasonable detail. HMR
shall have the primary right, but not the obligation, to institute, prosecute,
and control any action or proceeding with respect to such infringement of the
HMR Patent or Joint Patent, by counsel of its own choice, and Amylin shall have
the right to be represented in that action by counsel of its own choice. If HMR
fails to bring an action or proceeding within a period of ninety (90) days after
having knowledge of that infringement, Amylin shall have the right to bring and
control any such action by counsel of its own choice, and HMR shall have the
right to participate in such action and be represented by counsel of its own
choice. If one Party brings any such action or proceeding, the second Party
agrees to be joined as a party plaintiff and to give the first Party reasonable
assistance and all authority to file and prosecute the suit as may be necessary.
The costs and expenses of the Party bringing suit under this Section 9.5(b)
(including the internal costs and expenses specifically attributable to said
suit) shall be reimbursed first out of any damages or other monetary awards
recovered in favor of the Parties. Any remaining damages shall be split
******************* to HMR and ******************* to Amylin if HMR institutes
and controls such suit. However, if Amylin institutes and controls such suit,
any damage recovery shall be treated as Royalty-Bearing Sales and HMR shall
receive a portion of such damages equal to the applicable royalty rate
(expressed as a percentage) payable to HMR on said Royalty-Bearing Sales and all
remaining damages shall be distributed to Amylin.

                (c)     No settlement or consent judgment or other voluntary
final disposition of a suit under this Section 9.5 may be entered into without
the joint consent of Amylin and HMR.

                (d)     Notwithstanding the provisions of Section 9.1 and this
Section 9.5, neither Party shall file and prosecute an action for infringement
of a Patent for which the other Party has the primary responsibility to file and
prosecute such action, and pursuant to which that other Party having primary
responsibility has commenced and is prosecuting at least one such action for
infringement of said Patent, without the agreement of that other Party.

        9.6     COLLABORATION PATENT EXPENSES. Prior to the first commercial
sale of a Collaboration Product, Collaboration Patent Expenses shall be borne
equally by the Parties. Within thirty (30) days following the end of each
calendar quarter, each Party shall deliver a report outlining its Collaboration
Patent Expenses for such quarter. Within forty-five (45) days following the end
of each such quarter, the Party incurring less than one-half of the aggregate
combined total of such reported Collaboration Patent Expense during the quarter
shall reimburse the other Party an amount sufficient to equalize each Party's
one-half share of such combined

Collaboration Patent Expenses. Following the first commercial sale of a
Collaboration Product, Collaboration Patent Expenses will be treated as an
Allowable Expense.

        9.7     ASSIGNMENT OF JOINT PATENTS. Neither Party may assign its rights
under any Joint Patent except with the prior written consent of the other Party;
provided, however, that either Party may assign such rights without consent to
an Affiliate or other permitted assignee under this Agreement in connection with
a merger or similar reorganization or the sale of all or substantially all of
its assets, as provided in Section 15.1(b).

        9.8     TRADEMARKS.

                9.8.1   PRODUCT TRADEMARKS. The JCC shall oversee the selection,
prosecution of applications for, and maintenance of, trademarks in the
applicable country for each Collaboration Product and shall designate which of
the Parties shall be responsible for the related work. Under the supervision of
the JCC, the Parties shall work together and seek to agree on the selection of
trademarks for Collaboration Products for use in those countries where the
subject trademarked product is to be marketed, whether as a Collaboration
Product or as a Royalty-Bearing Product. In the event that the Parties cannot
agree on a trademark for any Collaboration Product as a result of said joint
selection efforts, HMR shall have the right to present three qualified
trademarks that have been identified by the Parties to Amylin, and Amylin shall
have the right to refuse any two such trademarks. The remaining trademark shall
be the selected trademark for the subject Collaboration Product and shall be
owned jointly by Amylin and HMR. To the extent expenses are incurred hereunder
prior to the first commercial sale of the applicable Collaboration Product, such
expense shall be treated as a Pre-Marketing Expense and thereafter, such
expenses shall be treated as Allowable Expenses. Collaboration Products shall be
sold under at least one trademark owned jointly by HMR and Amylin. All uses of a
jointly owned trademark(s) to identify a Collaboration Product, whether sold as
a Collaboration Product or as a Royalty-Bearing Product, shall comply with all
applicable laws and regulations, and those laws and regulations particularly
applying to the proper use and designation of trademarks in the countries of the
Profit Sharing Territory or in Royalty-Bearing Countries, as applicable. Jointly
owned trademark(s) shall be used only pursuant to the terms of this Agreement to
identify Collaboration Products or Royalty-Bearing Products, and shall not be
used by either Party to identify any other products. All jointly-owned
trademarks shall be registered by HMR in the names of Amylin and HMR as joint
owners in all countries where said marks will be used.

                9.8.2   INFRINGEMENT OF TRADEMARKS. HMR shall take all
reasonable and appropriate steps to protect, defend and maintain each jointly
owned trademark for use by the Parties in connection with a Collaboration
Product or Royalty-Bearing Product, and all registrations therefor, and each
Party shall notify the other Party promptly upon learning of any actual, alleged
or threatened infringement of a jointly-owned trademark or of any unfair trade
practices, trade dress imitation, passing off of counterfeit goods or like
offenses. Upon learning of such offenses HMR shall have the right but not the
obligation to, in consultation with Amylin,

                                      -39-
<PAGE>   46

institute and control an appropriate action or proceeding to halt the offense.
Amylin shall have the right to participate fully in all such actions or
proceedings.

                9.8.3   COSTS OF DEFENSE. All of the unrecovered costs, expenses
and legal fees (including internal costs, expenses and legal fees) in bringing,
maintaining and prosecuting any action to maintain, protect or defend a
trademark (or registration therefor) covering (i) a Collaboration Product shall
be an Allowable Expense in the applicable country or (ii) a Royalty-Bearing
Product shall be a deduction from Royalty-Bearing Sales, and any recovery shall
be Net Sublicense Revenue in that country.

                                    ARTICLE X

                         REPRESENTATIONS AND WARRANTIES

                Each of the Parties hereby represents and warrants to the other
Party as follows:

                (a)     This Agreement is a legal and valid obligation binding
upon such Party and enforceable in accordance with its terms. The execution,
delivery and performance of the Agreement by such Party does not conflict with
any agreement, instrument or understanding, oral or written, to which it is a
Party or by which it is bound, nor violate any law or regulation of any court,
governmental body or administrative or other agency having jurisdiction over it.

                (b)     Such Party has not, and during the term of the Agreement
will not, grant any right to any Third Party relating to its respective Patents
and know-how in the Field which would conflict with the rights granted to the
other Party hereunder.

                                   ARTICLE XI

                             INFORMATION AND REPORTS

        11.1    INFORMATION AND REPORTS DURING DEVELOPMENT AND
COMMERCIALIZATION. HMR and Amylin will disclose and make available to each other
all preclinical, clinical, regulatory, commercial marketing, promotion, pricing,
sales and other Information, including copies of all preclinical and clinical
reports, known by HMR or Amylin directly concerning Collaboration Compounds or
Collaboration Products at any time during the term of this Agreement. All
significant Information will be disclosed to the other Party promptly after it
is learned or its significance is appreciated. Each Party shall own and maintain
its own database of clinical trial data accumulated from all clinical trials of
Collaboration Products for which it was responsible and of adverse drug event
information for all Collaboration Products. At the option of the requesting
Party, such data shall be provided in a computer readable format by the
providing Party, to the extent available, which shall also assist in the
transfer and validation of such data to the receiving Party. Without limitation
of the foregoing, each Party shall supply to 

                                      -40-
<PAGE>   47

the other the Information required by the other Party and requested by it
(either as a routine practice or as a specific request) for purposes of
compliance with regulatory requirements.

        11.2    COMPLAINTS. Each Party shall maintain a record of all complaints
it receives with respect to any Collaboration Product or Royalty-Bearing Product
in accordance with its own established record keeping procedures for
pharmaceutical products of comparable market potential. Each Party shall notify
the other of any such complaint received by it in sufficient detail and within
five (5) business days after receipt, and in any event in sufficient time to
allow the responsible Party to comply with any and all regulatory requirements
imposed upon it in any country.

        11.3    ADVERSE DRUG EXPERIENCES. The Parties recognize that the holder
of a Drug Approval Application may be required to submit information and file
reports to various governmental agencies on (i) Collaboration Products and
Royalty-Bearing Products under clinical investigation, (ii) Collaboration
Products and Royalty-Bearing Products proposed for marketing or (iii) marketed
Collaboration Products and Royalty-Bearing Products. Information must be
submitted at the time of initial filing for investigational use in humans and at
the time of a request for market approval of a new Collaboration Product and
Royalty-Bearing Product. In addition, supplemental information must be provided
on Collaboration Products and Royalty-Bearing Products at periodic intervals and
adverse drug experiences must be reported at more frequent intervals depending
on the severity of the experience. Consequently, each Party agrees to:

                (a)     provide to the other Party for initial and/or periodic
submission to government agencies significant information on the Collaboration
Product and Royalty-Bearing Product from preclinical laboratory, animal
toxicology and pharmacology studies, as well as adverse drug experience reports
from clinical trials and commercial experiences with the Collaboration Product
and Royalty-Bearing Product;

                (b)     in connection with investigational Collaboration
Products and Royalty-Bearing Products, report to the other Party within
twenty-four (24) days of the initial receipt of a report of any unexpected or
serious experience with the drug, if required for either Party to comply with
regulatory requirements; and

                (c)     in connection with marketed Collaboration Products and
Royalty-Bearing Products, report to the other Party within five (5) working days
of the initial receipt of a report of any adverse experience with the drug that
is serious and unexpected or sooner if required for either Party to comply with
regulatory requirements. "Serious" adverse experience means any experience that
suggests a significant hazard, contraindication, side effect or precaution, or
any experience that is fatal or life threatening, is permanently disabling,
requires or prolongs inpatient hospitalization, or is a congenital anomaly,
cancer or overdose. "Unexpected" adverse experience means an adverse experience
not identified in nature, specificity, severity or 

                                      -41-

frequency in the current investigator brochure or the U.S. labeling for the
drug. Each Party also agrees that if it contracts with a Third Party for
research to be performed by such Third Party on a Product, that Party agrees to
require such Third Party to report to the contracting Party the information set
forth in subsections (a), (b), and (c) of this Section 11.3

        11.4    RECORDS OF REVENUES AND EXPENSES. Each Party will maintain
complete and accurate records which are relevant to revenues, costs, expenses
and payments under this Agreement, and such records shall be open during
reasonable business hours for a period of five (5) years from creation of
individual records for examination at the other Party's expense and not more
often than once each year by a certified public accountant selected by the other
Party for the sole purpose of verifying for the inspecting Party the correctness
of calculations and classifications of such revenues, costs, expenses or
payments made under this Agreement. In the absence of material discrepancies
(in excess of 5%) in any request for reimbursement resulting from such audit,
the accounting expense shall be paid by the Party requesting the audit. If
material discrepancies do result, the audited Party shall bear the accounting
expense. Any records or accounting information received from the other Party
shall be confidential information.

                                   ARTICLE XII

                              TERM AND TERMINATION

        12.1    TERM. This Agreement shall commence as of the Effective Date
and, unless sooner terminated as provided herein, shall continue in effect until
the date on which the Parties are no longer developing, marketing or selling in
any country (i) a Royalty-Bearing Product or an Independent Product for which,
in either case, royalties are or may be owed by one Party to the other Party, or
(ii) a Collaboration Product.

        12.2    TERMINATION FOR MATERIAL BREACH.

                (a)     Subject to the provisions of this Section 12.2, if
either Party (the "Breaching Party?) shall have committed a Material Breach (as
defined below) and such Material Breach shall remain uncured and shall be
continuing for a period of ninety (90) days following receipt of written notice
thereof by the other Party (the "Non-Breaching Party"), then, in addition to any
and all other rights and remedies that may be available, the Non-Breaching Party
shall have the right to terminate this Agreement effective upon the expiration
of such ninety (90) day period. Any such written notice of alleged Material
Breach by the Non-Breaching Party shall include a reasonably detailed
description of all relevant facts and circumstances demonstrating, supporting
and/or relating to each such alleged Material Breach by the Breaching Party.

                (b)     If the Breaching Party, upon written notice delivered to
the Non-Breaching Party prior to the expiration of such ninety (90) day period,
shall assert in good faith that any

such alleged Material Breach described in the Non-Breaching Party's notice,
whether in payment of moneys or otherwise, was not a Material Breach, or was
excused by reason of material failure of performance by the other Party or Third
Parties or by reason of Force Majeure (as defined in Section 15.4), or shall
otherwise in good faith dispute such alleged Material Breach, then the Parties
shall continue to perform under this Agreement, subject to all of its terms and
conditions, and the matter shall be resolved pursuant to the dispute resolution
provisions of Article XII of the License Agreement. In such event, the
Non-Breaching Party shall not be entitled to terminate this Agreement pursuant
to this Section 12.2 unless and until (i) it shall be determined pursuant to the
dispute resolution provisions of Article XII of the License Agreement that the
Breaching Party has committed a Material Breach and (ii) such Material Breach
has not been cured prior to such determination. To the extent that it is
determined pursuant to a final and non-appealable decision under the dispute
resolution provisions of Article XII of the License Agreement that the Breaching
Party did commit a Material Breach and failed to cure the same within the period
provided for in clause (ii) of this Section 12.2(b), then the Non-Breaching
Party may immediately terminate this Agreement and, in addition to all damages
determined pursuant to the dispute resolution provisions of Article XII of the
License Agreement to be due and owing from the Breaching Party to the
Non-Breaching Party under this Agreement, the Breaching Party shall be liable
for the Non-Breaching Party's reasonable attorney's fees incurred in connection
with resolving such matter.

                (c)     If the Non-Breaching Party terminates this Agreement
pursuant to the provisions of Sections 12.2(a) and (b), then the following
provisions shall apply:

                        (i)     the Non-Breaching Party shall receive, to the
        extent not already granted in this Agreement or the License Agreement,
        an exclusive (even as to the Breaching Party but subject to rights of
        Third Parties that are not Affiliates of the Breaching Party that
        pre-existed or accrued prior to such termination) worldwide right and
        license, with the right to grant sublicenses, to all HMR Patents or
        Amylin Patents, as applicable, of the Breaching Party and all of the
        Breaching Party's interest in jointly owned trademarks pursuant to
        Section 9.8.1, to make, have made, import, use, sell, offer for sale and
        have sold Collaboration Products, Royalty-Bearing Products and
        Independent Products, subject to the royalty obligations set forth below
        in Section 12.2(c)(ii), and shall have the exclusive right (but not the
        obligation) to enforce the Patents against Competitive Product
        Infringement and the exclusive right (but not the obligation) to enforce
        the trademark rights against infringers;

                        (ii)    the Breaching Party shall be entitled to receive
        royalties with respect to Collaboration Products at royalty rates of

        Products and Royalty-Bearing Products at ******** the royalty rates
        provided for in Section 4.8(b) and Section 5.7(a) of this Agreement,
        respectively; and

                        (iii)   the provisions of Sections 6.4(b) and 6.5
        through 6.10 shall apply with respect to royalties payable under this
        Section 12.2.

                (d)     In the event of termination of this Agreement pursuant
to this Section 12.2, the Breaching Party shall use its best efforts to cause
the transfer of all INDs, Drug Approval Applications and Regulatory Approvals
related to Collaboration Compounds, Collaboration Products, Royalty-Bearing
Products and Independent Products to the Non-Breaching Party, and take such
other actions and execute such other instruments, assignments and documents as
may be necessary to effect the transfer of rights hereunder to the Non-Breaching
Party.

                (e)     In the event of termination of this Agreement pursuant
to this Section 12.2 where HMR is the Breaching Party and HMR is manufacturing
in whole or in part one or more Collaboration Compounds, Collaboration Products
or Royalty-Bearing Products hereunder, HMR shall continue to provide for
manufacture of such Collaboration Compounds, Collaboration Products and
Royalty-Bearing Products to the extent provided prior to notice of such
termination, from the effective date of such termination until such time as
Amylin is able to secure an equivalent alternative commercial manufacturing
source, as requested by Amylin. To this end, as of the effective date of such
termination, all Third Party manufacturing contracts that are assignable shall
be assigned to Amylin, and the cost charged to Amylin by HMR for any of the
internal manufacturing activities to be continued by HMR pursuant to this
Section 12.2 for the production of Collaboration Products and Royalty-Bearing
Products shall be the same as HMR's direct cost was while the Agreement was in
effect; provided, however, that HMR may receive a profit for its internal
manufacturing activities relating to such Products at a rate of ***************
*******************************************************************************
********************************************************************************
Further, upon Amylin's request, HMR shall provide such technical assistance and
know-how licenses on a royalty free basis as may reasonably be requested to
transfer such technology as is needed by Amylin to commence or continue
commercial manufacture of Collaboration Products and Royalty-Bearing Products.
Such technical assistance shall be provided at HMR's direct cost, which cost
shall be reimbursed within thirty (30) days upon receipt of an invoice from HMR
by Amylin or its designee. In the event that any technology needed by Amylin to
commence or continue commercial manufacture of Collaboration Products and
Royalty-Bearing Products is covered by one or more HMR Patents, Amylin shall
receive a fully paid-up, royalty-free, non-exclusive worldwide license to
practice any and all such HMR Patents for the purposes contemplated in this
Section 12.2(e) together with the right to grant sublicenses.

                (f)     Except where expressly provided for otherwise in this
Agreement, termination of this Agreement shall not relieve the Parties hereto of
any liability, including any obligation to make payments hereunder, which
accrued hereunder prior to the effective date of such termination, nor preclude
any Party from pursuing all rights and remedies it may have

hereunder or at law or in equity with respect to any breach of this Agreement,
nor prejudice any Party's right to obtain performance of any obligation.

                (g)     For purposes of this Section 12.2, "Material Breach"
shall mean the breach or failure to perform, in a material respect, a Party's
material obligations under this Agreement. Without limiting the foregoing and by
way of example only, the term "Material Breach" shall be deemed to include the
failure of any Party in a material respect to meet such Party's payment or
non-compete obligations. In no event shall a failure to gain Regulatory Approval
for a Collaboration Product or to meet timelines or budgets specified in any
Research and Development Plan, Research and Development Budget,
Commercialization Plan, Commercialization Budget, Launch Plan or Launch Budget,
in and of itself, be deemed to constitute a Material Breach, unless such failure
is a result of acts and events or conduct that is otherwise a Material Breach.

                (h)     The provisions of this Section 12.2 shall survive
termination of this Agreement.

        12.3    TERMINATION WITHOUT A MATERIAL BREACH.

                (a)     Each Party shall have a continuing right to terminate
this Agreement for any reason, effective upon six (6) month advance written
notice to the other Party, subject to this Section 12.3.

                (b)     If either Party terminates pursuant to this Section
12.3, it shall continue to be obligated during the termination notice period to
perform all of its obligations under this Agreement. In addition, as a result of
such termination:

                        (i)     all licenses and rights granted by the
        non-terminating Party to the terminating Party hereunder shall
        terminate;

                        (ii)    to the extent not already granted in this
        Agreement or the License Agreement, the non-terminating Party shall
        receive an exclusive (even as to the terminating Party but subject to
        rights of Third Parties that are not Affiliates of the terminating Party
        that pre-existed or accrued prior to such termination) worldwide right
        and license, with the right to grant sublicenses, to all Patents of the
        terminating Party to import, use, sell, offer for sale and have sold
        Products for use in the Field, subject to the applicable royalty
        obligations set forth in Section 12.3(c) below, and shall have the right
        (but not the obligation) to enforce the Patents against Competitive
        Product Infringement (in the manner contemplated under and pursuant to
        the terms of Section 9.5(a) applicable to the terminating Party's
        Patents in the event that the terminating Party does not or will not so
        enforce the Patents) and the exclusive right (but not the obligation) to
        enforce the trademark rights against infringers;

                        (iii)   all Confidential Information supplied by the
        non-terminating Party to the terminating Party shall be destroyed by the
        terminating Party; provided, however, the terminating Party may retain
        one copy of such information solely for legal archive purposes;

                        (iv)    if HMR is the terminating Party, HMR shall be
        obligated under Section 8.5 to the extent provided therein;

                        (v)     the terminating Party shall cooperate in the
        transfer of all INDs, Drug Approval Applications and Regulatory
        Approvals related to Collaboration Compounds and the Products, to the
        non-terminating Party, and shall take such other actions and execute
        such other instruments, assignments and documents as may be necessary to
        effect the transfer of rights hereunder to the non-terminating Party;
        and

                        (vi)    the terminating Party shall not exploit or
        commercialize Joint Patents or jointly-owned trademarks in competition
        with the non-terminating Party's commercialization of the HMR Compounds.

                (c)     The terminating Party under this Section 12.3 shall be
entitled to a royalty of 6% of worldwide Royalty-Bearing Sales of products
incorporating HMR Compounds, which royalty shall be paid in accordance with the
provisions of Sections 6.5 through 6.10 of this Agreement.

        12.4    SURVIVING RIGHTS. The rights and obligations set forth in this
Agreement shall extend beyond the term or termination of the Agreement only to
the extent expressly provided for herein, or the extent that the survival of
such rights or obligations are necessary to permit their complete fulfillment or
discharge. Without limiting the foregoing, the Parties have identified various

Articles XIV and XV.

        12.5    ACCRUED RIGHTS, SURVIVING OBLIGATIONS. Termination,
relinquishment or expiration of this Agreement for any reason shall be without
prejudice to any rights which shall have accrued to the benefit of either Party
prior to such termination, relinquishment or expiration, including damages
arising from any breach hereunder. Such termination, relinquishment or
expiration shall not relieve either Party from obligations which are expressly
indicated to survive termination or expiration of the Agreement.

                                  ARTICLE XIII

                                 INDEMNIFICATION

                (a)     HMR hereby agrees to save, defend and hold Amylin and
its agents and employees harmless from and against any and all suits, claims,
actions, demands, liabilities, expenses and/or losses, including reasonable
legal expenses and attorneys' fees (collectively, "Losses"), resulting directly
from the manufacture, use, handling, storage, sale or other disposition of
Royalty-Bearing Products by HMR, its agents or sublicensees except to the extent
such Losses result from the negligence or willful misconduct of Amylin, its
agents or sublicenses.

                (b)     In the event that Amylin is seeking indemnification
under Section 13.1(a), it shall inform HMR of a claim for Losses as soon as
reasonably practicable after it receives notice of such claim, shall permit HMR
to assume direction and control of the defense of such claim (including the
right to settle the claim solely for monetary consideration), and shall
cooperate as requested (at the expense of HMR) in the defense of the claim.

        13.2    INDEMNIFICATION FOR COLLABORATION PRODUCTS. With respect to
Collaboration Products:

                (a)     Each Party hereby agrees to save, defend and hold the
other Party and its agents and employees harmless from and against any and all
Losses resulting directly or indirectly from the manufacture, use, handling,
storage, sale or other disposition of Collaboration Products by the indemnifying
Party, its agents or sublicensees, but only to the extent such Losses result
from the negligence or willful misconduct of the indemnifying Party or its
employees and agents and do not also result from the negligence or willful
misconduct of the Party seeking indemnification. Any other Losses from claims
resulting directly or indirectly from the 


                                      -47-
<PAGE>   54

manufacture, use, handling, storage, sale or other disposition of Collaboration

misconduct of the Party seeking indemnification.

                (b)     In the event that either Party receives notice of a

        15.1    ASSIGNMENT.

                (a)     Either Party may assign any of its rights or obligations
under this Agreement in any country to any Affiliates; provided, however, that
such assignment shall not 

                                      -48-
<PAGE>   55

relieve the assigning Party of its responsibilities for performance of its
obligations under this Agreement.

                (b)     Either Party may assign its rights or obligations under
this Agreement or its ownership interest in Joint Patents to a non-Affiliate
only as provided in Section 9.7, or in connection with a merger or similar
reorganization or the sale of all or substantially all of its assets, or
otherwise with the prior written consent of the other Party. This Agreement
shall survive any such merger or reorganization of either Party with or into, or
such sale of assets to, another party and no consent for such merger,
reorganization or sale shall be required hereunder; provided, however, that in
the event of such merger, reorganization or sale, no intellectual property
rights of the acquiring corporation shall be included in the technology licensed

Either Party may assign its rights and obligations under this Agreement to an
entity or entities (e.g., partnership or corporation) that are specifically
formed for financial purposes and that finance Research, Development or
Commercialization performed by such Party pursuant to this Agreement; provided,
however, that such assignment shall not relieve the assigning Party of
responsibility for performance of its obligations under this Agreement.

in this Agreement for either Party to secure the consent or approval of the
other, that consent or approval shall not unreasonably be withheld, and whenever
in this Agreement provision is made for one Party to object to or disapprove a
matter, such objection or disapproval shall not unreasonably be exercised.

        15.4    FORCE MAJEURE. Neither Party shall lose any rights hereunder or
be liable to the other Party for damages or losses on account of failure of
performance by the defaulting Party if the failure is occasioned by government
action, war, fire, explosion, flood, strike, lockout, embargo, act of God, or
any other similar cause beyond the control of the defaulting Party, provided
that the Party claiming force majeure has exerted all reasonable efforts to
avoid or remedy such force majeure; provided, however, that in no event shall a
Party be required to settle any labor dispute or disturbance.

        15.5    INCORPORATION OF LICENSE AGREEMENT PROVISIONS; CONFLICTING
PROVISIONS. Upon the Effective Date of this Agreement, the terms and conditions
of the License Agreement are hereby incorporated by reference into this
Agreement, except the provisions of the License Agreement that are superseded by

                                    EXHIBIT A
                    DETERMINATION OF CERTAIN ACCOUNTING TERMS
<PAGE>   60
                                    EXHIBIT A

                    DETERMINATION OF CERTAIN ACCOUNTING TERMS

        As a supplement to the definitions provided in Article 1 of this
Agreement, the following accounting terms shall be further specified as follows.
As used herein, the term "operating unit" shall mean the smallest operating unit
in which an operating profit and loss statement is prepared for management
accounting purposes in the Party's normal accounting procedures, consistently
applied within and across its operating units.

        1.     COST OF GOODS SOLD

        Cost of Goods Sold shall be equal to the Standard Cost of each unit of
Collaboration Product sold plus Other Costs Not In Standard incurred during the
period, subject to limitation as provided in Item C below.

        A.     "STANDARD COST" shall include the following:

               1) Material Cost shall mean the prices paid for raw material
components and purchased Finished Goods which are purchased from outside vendors
as well as any freight and duty where applicable.

                      Standard Material Cost includes the quantity of the
components included in the Bill of Material times the purchase price and the
waste factor (i.e., scrap percentage) included in the Bill of Materials. It also
includes the normal costed Quality Assurance sample quantity which is included
in the Bill of Materials. Raw Material prices shall be adjusted on an annual
basis by Purchasing.

               2) Direct Labor Costs shall mean the standard labor hours
required for an operation according to the Standard Operating Procedures for
such Collaboration Product multiplied by the Direct Labor Rate for work centers
within the relevant manufacturing operating unit.

               3) Overhead Costs shall mean other costs associated with the
operating unit(s) manufacturing a Collaboration Product, provided, however, that
such Overhead Costs shall exclude costs associated with unused manufacturing
capacity and any administrative costs other than indirect labor of the
Manufacturing Department specifically attributable to the Collaboration Product
in question. Overhead Costs shall include expenses associated with Quality
Assurance, Manufacturing and Engineering associated with the operating unit(s)
manufacturing a Collaboration Product and shall include Depreciation and
Property Taxes associated with the plant(s) manufacturing a Collaboration
Product. These costs shall be allocated to each product line in such operating
unit(s) or plant(s), whichever is applicable, based on specific criteria
consistent with the standard operating procedures for each product and work
center overhead rates of the Party performing the work determined and allocated
in a manner consistently applied within and across its operating units (except
as specifically provided in Item C below).

                                       1
<PAGE>   61



               4)  Manufacturing Variances shall include:

                      (a) Purchase Price Variance shall mean the difference
between the actual price paid the vendor versus the standard cost of such
material, times the quantity received.

                      (b) Spending Variance shall mean the difference between
actual department spending and the budgeted spending included in Standard Cost
for the relevant manufacturing operating unit.

                      (c) Absorption volume variances shall mean the difference
between actual product hours earned (or units produced) and the hours budgeted
for the period (or projected production units used) in the development of
Standard Costs times the standard labor and overhead content of those units.

                      (d) Material usage shall mean the difference between the
actual quantity of component raw materials or work-in-process used in the
production of work-in-process or finished goods versus the standard quantity
included in the Bill of Materials times the standard cost of the component or
work-in-process item.

                      (e) Rework shall mean the additional standard cost of
components or work-in-process items used to turn rejected inventory into usable
inventory. No labor or overhead rate is assigned to rework orders, only the
additional value of the inventory which is issued to the other. Additionally, no
production/absorption credit is generated for rework orders since the credit was
already generated the first time the production occurred.

        B.  "OTHER COSTS NOT IN STANDARD" shall include:

               1) Scrap Expense shall mean the total standard cost of inventory
which is physically destroyed or transferred to Rejected Inventory awaiting
disposition. Total Cost means total inventory value which includes material,
labor and overhead.

               2) Inventory revaluation shall mean under FIFO Inventory
Valuation the difference between the prior year's ending inventory at the prior
year's standard cost plus or minus the year-end full absorption adjustment (see
below) versus the same inventory at the new year's standard cost.

               3) Full Absorption Adjustment -- Under FIFO Inventory Valuation
the monthly adjustment which is made to adjust inventories from standard to
actual cost. This involves reserving a period of the Manufacturing Variances,
beginning with the current month and going back according to the number of
month's supply of inventory on hand at the end of each month or annually as the
case may be.

               4) Excess and Obsolete Inventory Adjustments -- The P&L impact of
adjusting the reserves for excess and obsolete inventory up and down based upon
a quarterly analysis or 

                                       2.
<PAGE>   62

annually as the case may be.

               5) Loss on Returns Expense -- These are expenses (similar to
sales returns and allowances) which are incurred as a result of issuing
reasonable sales credits to customers at standard cost. This is the offset to
reversing the standard cost of sales when the sale is negated.

               6) No Charge Shipments -- Those expenses associated with shipping
replacement product to customers at no charge. This is the offset to relieving
inventory at standard cost when the product is shipped.

        C.     EXCLUDED COSTS. Notwithstanding the foregoing, Cost of Goods
Sold shall exclude administrative costs other than indirect manufacturing labor
specifically attributable to the Collaboration Product being manufactured and
shall exclude allocation of unused capacity costs.

        2.     MARKETING EXPENSES

        Marketing Expenses shall be the sum of Selling Expenses, Marketing
Management, Market and Consumer Research, Advertising, Trade Promotion, Consumer
Promotion, and Education Expenses, each of which is specified below.

        A.     "SELLING EXPENSES" shall include the following costs directly
associated with the efforts of field sales representatives with respect to
Collaboration Products: field sales force; field sales offices; home offices
staffs directly involved in the management of and the performance of the selling
functions; payments to Third Parties under co-promotion agreements approved by
the Steering Committee. Reasonable field samples shall normally be charged to
Trade Promotion, but if sales management has direct decision making authority
for the distribution of field sales samples, it may be appropriate to charge
these costs to Selling Expenses. The costs of detailing sales calls shall be
allocated on a weighted average basis based on what detail position the involved
Collaboration Product is assigned at an accounting charge rate consistently
applied within and across its operating units and which is no less favorable to
the collaboration than the internal charge rate used by HMR for its own internal
cost accounting purposes for products other than Collaboration Products
(excluding internal profit margins and markups).

        B.     "MARKETING MANAGEMENT" shall include Product Management and
Sales Promotion Management direct expenses. This shall include costs associated
with developing overall sales and marketing strategies and planning for
Collaboration Products. In addition, payments to Third Parties in connection
with trademark selection, filing, prosecution and enforcement shall be included
in this category.

        C.     "MARKET AND CONSUMER RESEARCH" shall include direct expenses for
Market and Consumer Research personnel and payments to Third Parties related to
conducting and monitoring professional and consumer appraisals of existing, new
or proposed Collaboration Products such as market share services (e.g., IMS
data), special research testing and focus groups.



                                       3.
<PAGE>   63


        D.      "ADVERTISING" shall include all direct media costs associated
with Collaboration Product advertising as follows: production expense/artwork
including set up; design and art work for an advertisement; the cost of securing
print space, air time, etc. in newspapers, magazines, trade journals,
television, radio, billboards, etc.

        E.      "TRADE PROMOTION" shall include reasonable allowances given to
retailers, brokers, distributors, hospital buying groups, etc. for purchasing,
promoting, and distribution of Collaboration Products. This shall include
purchasing, advertising, new distribution, and display allowances as well as
free goods, wholesale allowances and reasonable field sales samples. To the
extent multiple products are involved and some of such products are not
Collaboration Products then such allowances shall be allocated on a pro rata
basis based upon net sales of each respective product by such operating unit
during the most recent quarter.

        F.      "CONSUMER PROMOTION" shall include the direct expenses
associated with programs to promote Collaboration Products directly to the end
user. This category shall include direct expenses associated with promoting
products directly to the professional community such as professional samples,
professional literature, promotional material costs, patient aids and detailing
aids. To the extent multiple products are involved and some of such products are
not Collaboration Products then such allowances shall be allocated on a pro rata
basis based upon net sales of each respective product by such operating unit
during the most recent quarter.

        G.      "EDUCATION" shall include direct expenses associated with
professional education with respect to Collaboration Products through any means
not covered above, including articles appearing in journals, newspapers,
magazines or other media; seminars, scientific exhibits, and conventions; and
symposia, advisory boards and opinion leader development activities.

        H.      "ROYALTY EXPENSES" shall mean royalties or other compensation
payable to a Third Party under patents and/or technology rights of such Third
Party to conduct Commercialization pursuant to the Collaboration Agreement.

        3.      DISTRIBUTION EXPENSES

        Distribution Expenses shall be the sum of Stock and Shipping Expenses
and Transportation Expenses, each as specified below.

        A.      "STOCK AND SHIPPING" shall include the portion of distribution
costs for the warehousing of Collaboration Product finished goods from the point
of completion of production to the time the goods are turned over to a carrier
for delivery as follows: order filling/assembly functions; reasonable order
billing and customer service functions; reasonable portion of company
owned/leased facilities relating to warehousing of finished products; storage of
products at public warehouses.

        B.      "TRANSPORTATION" shall include the portion of distribution costs
relating to moving Collaboration Product goods from a warehouse to the customer
as follows: outbound 

                                       4.
<PAGE>   64

transportation costs; costs of moving goods from a manufacturing point to a
warehouse at another location from which it is ultimately to be distributed to a
customer.

        4.      POST-LAUNCH PRODUCT R&D EXPENSES

        Post-Launch Product R&D Expenses shall include certain research and
development costs incurred by a Party in relation to a Collaboration Product
after the first commercial launch and shall exclude administrative expenses.
Such post-launch research and development costs shall include:

        A.      Phase IV Clinical Trials.

        B.      Ongoing product support (as defined in Section 1.45 of the
Collaboration Agreement).

        C.      Ongoing medical affairs (as defined in Section 1.45 of the
Collaboration Agreement).

        D.      Preclinical research.

        E.      Contract R&D costs performed by others for a particular project
that have no alternative future uses in other R&D projects or otherwise.

        F.      Fees and expenses of outside counsel in respect of regulatory
affairs unrelated to obtaining Regulatory Approvals.

        5.      CURRENCY GAINS OR LOSSES

        Currency Gains or Losses shall include the following:

        A.      UNHEDGED TRANSACTIONS. Transaction gains or losses resulting
from a change in exchange rates between the functional currency and the currency
in which the transaction is denominated. The transaction gain or loss is
determined by measuring the increase or decrease in the functional currency cash
flow due to the changes in the exchange rate from the date of the transaction to
the settlement date. The difference between the functional currency amount
calculated using the current exchange rate at the transaction date and the
amount calculated using the currency exchange rate at the settlement date is the
transaction gain or loss. Transaction gains or losses on unsettled foreign
currency transactions are also reported in this manner. When there is a balance
sheet date between the transaction date and settlement date, the gain or loss on
the unsettled balance shall be measured using the current exchange rate at the
balance sheet date.

        B.      HEDGED TRANSACTIONS. For purposes of this collaboration, neither
Party shall buy or sell forward, directly or indirectly, foreign currencies in
amounts greater than those which can reasonably be expected to be received or
paid, as the case may be, over the relevant time period.

                                       5.
<PAGE>   65

If a Party enters into a hedged transaction, the gain or loss realized from the
hedge must be included in the underlying transaction. If the currency
transaction gain or loss has been included in Net Sales, Costs of Goods Sold,
etc., it shall not be included in this category.

        3.6    SELECTION OF HMR COMPOUNDS; HMR REPLACEMENT COMPOUNDS.

               3.6.1 SELECTION OF HMR PRIMARY COMPOUNDS FOR RESEARCH AND
DEVELOPMENT. Promptly after the Effective Date, Amylin will commence Research
and Development on *********** and ***********. Thereafter, from time to time in
Amylin's sole discretion, Amylin shall be entitled to initiate Research and
Development with respect to one or more additional HMR Compounds pursuant to
this Agreement and/or to discontinue Research or Development with respect to one
or more HMR Compounds, including but not limited to *********** and ***********.

               3.6.2  HMR REPLACEMENT COMPOUNDS.

                      (a) If Amylin determines at any time or from time to time,
        whether prior to or subsequent to the HMR Option Exercise Date, in its
        sole discretion, that ************************ or any other HMR Primary
        Compound is not suitable for Research, Development and/or
        commercialization pursuant to this Agreement, upon written notification
        of the same to HMR, Amylin shall thereupon be entitled to select an
        additional compound ("HMR Replacement Compound") from the HMR Series for
        Research, Development and/or commercialization pursuant to this
        Agreement to replace such HMR Primary Compound; provided, however, that
        (i) Amylin shall not be entitled to select more than ********* such HMR
        Replacement Compounds during the term of this Agreement and (ii) Amylin
        shall not be entitled to select any compound from the HMR Series with
        respect to which HMR or any of its licensees has initiated human
        clinical trials or is in active research as a clinical candidate prior
        to such notification by Amylin. HMR agrees to provide all information
        reasonably requested by Amylin from time to time with regard to
        compounds included in the HMR Series in order to allow Amylin to
        reasonably evaluate its rights under this Section 3.6.2 and the
        desirability of selecting an HMR Replacement Compound pursuant to this
        Section 3.6.2, including without limitation, all applicable HMR Data. At
        any time an HMR Replacement Compound is so selected by Amylin as a
        replacement for an HMR Primary Compound, the HMR Primary Compound so
        replaced (such compound hereinafter referred to as a "Terminated
        Compound") shall thereafter be excluded from the meaning of "HMR
        Compound" for all purposes of this Agreement.

                      (b) In the event Amylin begins and then discontinues
        Research and Development with respect to one or more HMR Compounds and
        does not select an HMR Replacement Compound pursuant to this Section
        3.6.2, then Amylin shall notify HMR in writing, and thereafter such HMR
        Compound shall be deemed a "Terminated Compound" and be excluded from
        the meaning of "HMR Compound" for all purposes of this Agreement.

               3.6.3 OTHER COMPOUNDS IN THE HMR SERIES. HMR shall be free to
develop or commercialize, or to license Third Parties to develop or
commercialize, the compounds in the HMR Series other than HMR Compounds;
provided, however, that HMR or its licensee(s) shall

not be entitled to develop or commercialize such other compounds in the HMR
Series for the prevention, treatment and/or diagnosis of cardiovascular or
metabolic diseases or disorders.

        3.7    REGULATORY MATTERS.

               3.7.1 COMPLIANCE WITH REGULATIONS. Amylin, and HMR to the extent
it is providing services pursuant to Sections 3.5.2(c), (d) and (e), will
conduct their efforts hereunder in compliance with all applicable regulatory
requirements, including without limitation, the FDA's Good Clinical Practice,
Good Laboratory Practice and Good Manufacturing Practice regulations and the
guidelines of the International Conference on Harmonization of Technical
Requirements for Registration of Pharmaceuticals for Human Use.

               3.7.2 REGULATORY FILINGS. Unless and until the HMR Option is
exercised, Amylin shall, at its own expense, prepare and submit all filings with
the regulatory authorities with respect to HMR Compounds in each country in the
Territory (the "Regulatory Filings"), and Amylin shall be responsible for
causing such applications to progress through the approval process on a timely
basis. In the event that the HMR Option is exercised, Regulatory Filings shall
be prepared and submitted in accordance with the provisions of the Collaboration
Agreement. HMR will provide the Drug Master File or appropriate reference to the
Drug Master File directly to the regulatory authorities in the countries in the
Territory, if applicable, and as may be required by law or regulation in such
country in the Territory. HMR shall reasonably cooperate with Amylin in such
manner as Amylin may reasonably request to assist in obtaining Regulatory
Approval for Products. The Research and Development Expenses incurred in
obtaining Regulatory Approval for HMR Compounds shall be allocated between the
Parties pursuant to the provisions of Section 3.5.3. Amylin shall, promptly
after filing, deliver to HMR copies of all Regulatory Filings and
correspondence, which shall be held by HMR subject to the provisions of Article
VI.

               3.7.3 MAINTENANCE OF RECORDS. Each Party shall maintain records
with respect to activities conducted in connection with Research and Development
of HMR Compounds in sufficient detail and in the manner appropriate for
Regulatory Approval purposes and in a manner which will reflect all studies
conducted, results achieved and data obtained by such Party in the course of
such Research and Development.

               3.7.4 SAFETY REPORTING. During the term of this Agreement
(regardless of whether the HMR Option has been exercised or expires
unexercised), the Parties shall, on a quarterly basis, exchange toxicological
and other similar reports relevant to the use, indications, Tolerability or
Safety of HMR Compounds.

                                   ARTICLE IV

            HMR'S OPTION TO PARTICIPATE IN RESEARCH, DEVELOPMENT AND
                                COMMERCIALIZATION

        4.1 HMR OPTION. HMR shall have a one-time right to elect to form a joint
venture with Amylin (in such legal form as the Parties may mutually agree) to
jointly research, develop and commercialize, and share profits and losses
associated with, the HMR Compounds (the "HMR Option") as follows:

               4.1.1 HMR OPTION NOTICE. Within thirty (30) days after the date
that the first HMR Compound has completed Pivotal Phase II Clinical Trials,
Amylin shall provide a written notice to HMR (the "Option Notice") which sets
forth in reasonable detail (i) the results of such Pivotal Phase II Clinical
Trials and (ii) all Research and Development Expenses incurred by Amylin with
respect to all HMR Compounds through the date of such notice and estimated for
the immediately subsequent thirty (30) day period (such Research and Development
Expenses being subject to verification by HMR and being referred to herein as
the "Amylin Research and Development Expenses").

               4.1.2 HMR OPTION REPLY. HMR shall exercise, or indicate its
decision not to exercise, the HMR Option by providing written notice of its
decision to Amylin within sixty (60) days following receipt by HMR of the Option
Notice (the "HMR Option Reply"). If no HMR Option Reply is received by Amylin
within sixty (60) days following receipt by HMR of the Option Notice, the HMR
Option will be deemed to have expired unexercised. If HMR determines to exercise
the HMR Option, then the date on which HMR delivers the HMR Option Reply is
referred to as the "HMR Option Exercise Date". If HMR exercises the HMR Option,
HMR shall set forth in reasonable detail in the HMR Option Reply all Research
and Development Expenses previously agreed to by the Parties and incurred by HMR
pursuant to this Agreement subsequent to the Effective Date and through the HMR
Option Exercise Date with respect to all HMR Compounds which have not been
reimbursed by Amylin or its Affiliates as provided in Section 3.5.3(b)(iii) (the
"HMR Additional Research and Development Expenses").

               4.1.3 In the event the HMR Option is exercised, HMR will pay to
Amylin, or Amylin will pay to HMR, as the case may be, the "Pre-Collaboration
Allocation Payment" (as defined in Section 2.2 of the Collaboration Agreement).

        4.2 LIMITATIONS OF FURTHER RIGHTS. HMR shall be entitled to only one HMR
Option. In the event HMR exercises the HMR Option, then on the HMR Option
Exercise Date, the Collaboration Agreement will become effective and the
provisions of such Collaboration Agreement will supersede, to the extent
applicable, the provisions of Sections 2.2-2.4, 3.1-3.5, 3.7.2, 4.1, 7.3.3, 7.5,
7.6 and 10.2-10.5 and Article V of this Agreement.

                                    ARTICLE V

                                    ROYALTIES

        5.1 ROYALTIES AND ROYALTY PAYMENTS. Subject to Section 5.2, Amylin shall
pay HMR a royalty equal to ****************** of Net Sales of Products with
respect to Net Sales up to U.S. ************ in any calendar year, and
******************** of Net Sales of Products with respect to Net Sales in
excess of U.S. ************ in any calendar year, sold by Amylin, its Affiliates
or permitted sublicensees pursuant to Section 5.4.

        5.2 DURATION OF ROYALTY OBLIGATIONS. Amylin's royalty obligation as to
each Product shall commence as of the date hereof and shall expire on a
country-by-country basis concurrently with the later to occur of (i) the
expiration of the last to expire of any issued patents within the HMR Patents or
Joint Patents in the country, or (ii) if no such Patent should issue in a
country, the tenth anniversary of the first commercial sale of the relevant
Product in such country.

        5.3 ROYALTY RATE IF GENERICS INTRODUCED. In the event that a generic
version of a Product is marketed in any country where no Patents within the HMR
Patents or Joint Patents have issued which would prevent the sale of such
generic version and the sales of such generic version of a Product in such
country is equal to at least ********************* of unit sales of the Product
being marketed by Amylin in such country, the royalty rate in that country will
be reduced to ******************* of the applicable royalty rate provided in
Section 5.1 until such time, and from time to time, that a Patent within the HMR
Patents or Joint Patents has issued which would prevent the sale of such generic
version or sales of the generic version of the Product in any calendar quarter
are reduced to less than ********************* of the unit sales of the Product
in such calendar quarter.

        5.4 SALES BY SUBLICENSEES. In the event Amylin grants licenses or
sublicenses to others to make or sell Products, such licenses or sublicenses
shall include an obligation for the licensee or sublicensee to account for and
report its Net Sales of such Products on the same basis as if such Net Sales
were sales by Amylin, and Amylin shall pay royalties to HMR as if the Net Sales
of the sublicensee were sales of Amylin. Amounts payable by the sublicensee to
Amylin on account of the sublicense shall not be included in amounts deducted
from gross sales in arriving at Net Sales.

        5.5 ROYALTY PAYMENTS AND REPORTS. A report summarizing the sales of any
Products during the relevant quarter shall be delivered to HMR within thirty
(30) days following the end of each calendar quarter and sixty (60) days
following the end of each calendar year for which royalties are due from Amylin.
Royalty payments under this Agreement shall be made to HMR or its designee
quarterly within thirty (30) days following the due date for the report in the
first sentence of this Section 5.5.

        5.6 TAXES. HMR shall pay any and all taxes levied on account of
royalties it receives under this Agreement. If laws or regulations require that
taxes be withheld, then Amylin will (i) deduct those taxes from the remittance
royalty, (ii) timely pay the taxes to the proper taxing authority and (iii) send
proof of payment to HMR within thirty (30) days following such payment.

        5.7 BLOCKED CURRENCY. In each country where the local currency is
blocked or cannot be removed from such country, at the election of HMR,
royalties shall accrue in that country or shall be paid to HMR in the country in
local currency by deposit in a local bank designated in writing by HMR.

        5.8 PAYMENTS TO OR REPORTS BY AFFILIATES. Any payment required under any
provision of this Agreement to be made to either Party or any report required to
be made by either Party shall be made to or by an Affiliate of that Party if
designated by that Party as the appropriate recipient or reporting entity.

        5.9 NO OVERLAPPING ROYALTIES. Notwithstanding any other provisions of
this Agreement, in no event shall any royalty provided for under any section of
this Agreement be paid with respect to any sale of a Product to the extent a
royalty has been paid pursuant to any other section of this Agreement with
respect to such sale.


                                   ARTICLE VI

                                 CONFIDENTIALITY

        6.1 CONFIDENTIALITY; EXCEPTIONS. Except to the extent expressly
authorized by this Agreement or otherwise agreed in writing or permitted by
Section 6.3. herein, the Parties agree that, the receiving Party shall keep
confidential and shall not publish or otherwise disclose or use for any purpose
other than as provided for in this Agreement any Information related to the HMR
Compounds or the Products and other information and materials furnished to it by
the other Party pursuant to this Agreement or any Information related to the HMR
Compounds or the Products developed during the term of this Agreement hereunder,
or any provisions of this Agreement that are the subject of an effective order
of the Securities and Exchange Commission granting confidential treatment
pursuant to the Securities Exchange Act of 1934, as amended (collectively,
"Confidential Information"), except to the extent that it can be established by
the receiving Party that such Confidential Information:

               (1) was already known to the receiving Party, other than under an
obligation of confidentiality, at the time of disclosure by the other Party;



                                      16.
<PAGE>   22


               (2) was generally available to the public or otherwise part of
the public domain at the time of its disclosure to the receiving Party;

               (3) became generally available to the public or otherwise part of
the public domain after its disclosure and other than through any act or
omission of the receiving Party in breach of this Agreement;

               (4) was disclosed to the receiving Party, other than under an
obligation of confidentiality, by a Third Party who had no obligation to the
disclosing Party not to disclose such information to others; or

               (5) was independently developed by the receiving Party without
breach of the provisions of this Agreement (and can be verified by the
disclosing Party as such).

        6.2 RECEIPT OF THIRD PARTY INFORMATION. Neither Party shall knowingly
receive documents containing Information related to the use of the HMR Compounds
in the Field under an obligation of confidentiality to Third Parties which
requires the Party receiving such documents to withhold access to the other
Party, without such Party's written consent.

        6.3 AUTHORIZED DISCLOSURE. Each Party may disclose Confidential
Information hereunder to the extent such disclosure is reasonably necessary in
(i) filing or prosecuting patent applications, (ii) prosecuting or defending
litigation, (iii) complying with applicable laws or regulations or (iv)
conducting preclinical or clinical trials, provided that if a Party is required
by law or regulation to make any such disclosure of the other Party's
Confidential Information it will, except where impracticable for necessary
disclosures (e.g., in the event of medical emergency), give reasonable advance
notice to the other Party of such disclosure requirement and, except to the
extent inappropriate in the case of patent applications, will use its reasonable
efforts to secure confidential treatment of such Confidential Information
required to be disclosed. In addition, and with prior notice to the other Party
of each Third Party with whom a confidential disclosure agreement is being
entered into, each Party shall be entitled to disclose, under a binder of
confidentiality containing provisions as protective as those of this Article VI,
Confidential Information to any Third Party for the purpose of carrying out the
purposes of this Agreement. Nothing in this Article VI shall restrict any Party
from using for any purpose consistent with the terms of this Agreement any
Information developed by it during the term of this Agreement. When a Party
makes a disclosure of the other Party's Confidential Information to any of its
employees, the Party making such disclosure shall ensure that such employees are
bound by written confidentiality agreements having substantially the same terms
as this Article VI.

        6.4 SURVIVAL. This Article VI (other than Section 6.2) shall survive the
termination or expiration of this Agreement for a period of the greater of (i)
seven (7) years and (ii) until the termination of the Collaboration Agreement.

        6.5 TERMINATION OF PRIOR AGREEMENT. This Agreement supersedes the
Confidentiality Agreement between Amylin and HMR dated April 5, 1996. All
Information exchanged between the Parties under that Agreement shall be deemed
Confidential Information and shall be subject to the terms of this Article VI,
and shall be included within the definitions of Amylin Know-how and HMR
Know-how.

        6.6 SCIENTIFIC PUBLICATIONS AND PRESENTATIONS. Unless or until the HMR
Option expires unexercised, each Party agrees that it shall not publish or
present Information or Confidential Information without the opportunity for
prior review by the other Party. Except as required by law, each Party shall
provide to the other the opportunity to review and approve any proposed
scientific publications and scientific presentations (including information to
be presented orally) which relate to the HMR Compounds or otherwise constitutes
Confidential Information as early as reasonably practical, but at least three
(3) weeks prior to their intended submission for publication (one (1) week for
abstracts) except, where applicable, with the written consent of an appropriate
employee of the other Party. Such submitting Party agrees, upon written request
from the other Party, not to submit such proposed publication for publication or
to make such presentation unless or until the other Party consents.


                                   ARTICLE VII

              OWNERSHIP OF INTELLECTUAL PROPERTY AND PATENT RIGHTS

        7.1 OWNERSHIP. Each Party shall solely own, and it alone shall have the
right to apply for Patents within and outside of the United States for any
inventions made solely by that Party's personnel or consultants in the course of
performing work under this Agreement. Inventions made jointly by personnel or
consultants of Amylin and HMR shall be owned jointly by Amylin and HMR. The law
of joint ownership of inventions of the United States shall apply to any joint
ownership of patents outside the United States claiming joint inventions of the
Parties.

        7.2 DISCLOSURE OF PATENTABLE INVENTIONS. In addition to the disclosures
required under Article IX, each Party shall provide to the other any invention
disclosure submitted in the normal course of performing its obligations
hereunder which discloses an invention related to the HMR Compounds in the Field
or the Products. Such invention disclosures shall be provided to the other Party
promptly after submission and in no event later than ten (10) days after the end
of the calendar quarter in which the disclosure was submitted, provided,
however, that no disclosure is required that would constitute publication prior
to the time a patent issues.

        7.3    PATENT FILINGS.

               7.3.1 AMYLIN AND JOINT PATENTS. Amylin shall prepare, file, and
prosecute Patents for (i) inventions relating to HMR Compounds that are made
solely by Amylin personnel and consultants (all of which shall be issued in
Amylin's name and shall be Amylin Patents), and 

                                      18.
<PAGE>   24

(ii) inventions relating to HMR Compounds that are made jointly by personnel and
consultants of Amylin and HMR in the course of the performance of the Parties'
obligations under this Agreement or the Collaboration Agreement (which shall be
issued in HMR's and Amylin's joint name and shall be "Joint Patents"), and will
use reasonable efforts to file initially all such applications in the United
States. With respect to (i) Joint Patents only (prior to and after the delivery
of the HMR Option Reply, regardless of whether HMR exercises the HMR Option) and
(ii) both Joint Patents and Amylin Patents (only if HMR exercises the HMR
Option): (A) the determination of the countries outside of the United States in
which to file such patent applications shall be made by mutual agreement of the
Parties (if, however, there is a dispute as to where to file, the more
comprehensive filing will be made); (B) Amylin shall keep HMR informed of the
status of such Patents and shall seek the advice of HMR with respect to such
Patent strategy and draft applications and shall give reasonable consideration
to any suggestions or recommendation of HMR concerning the preparation, filing,
prosecution and maintenance thereof; (C) the Parties shall cooperate in good
faith in the prosecution of such Patents and shall share all material
Information relating thereto promptly after receipt of such Information; and (D)
if, during the term of this Agreement, Amylin intends to allow any Amylin
Patents under which HMR has a right to a license under this Agreement, to lapse
or become abandoned without having first filed a substitute, Amylin shall,
whenever practicable, notify HMR of such intention at least sixty (60) days
prior to the date upon which such Amylin Patent shall lapse or become abandoned,
and HMR shall thereupon have the right, but not the obligation, to assume
responsibility for the prosecution and maintenance thereof.

               7.3.2 HMR PATENTS. HMR shall file, prosecute and be entitled to
be issued in its name Patents to cover inventions relating to HMR Compounds that
are made solely by HMR personnel and consultants (all of which will be HMR
Patents), and will use reasonable efforts to file initially all such
applications in the United States. The determination of the countries outside of
the U.S. in which to file shall be made by mutual agreement of the Parties. If,
however, there is a dispute as to where to file, the more comprehensive filing
shall be made. In the case where Amylin requests worldwide filing, HMR shall at
least file in the following countries: United States, Canada, Japan and all
European Patent Office countries. HMR shall keep Amylin informed of the status
of each HMR Patent and shall seek the advice of Amylin with respect to HMR
Patent strategy and draft applications and shall give reasonable consideration
to any suggestions or recommendations of Amylin concerning the preparation,
filing, prosecution and maintenance thereof. The Parties shall cooperate
reasonably in the prosecution of all applications for HMR Patents and shall
share all material Information relating thereto promptly after receipt of such
Information. If, during the term of this Agreement, HMR intends to allow any HMR
Patent under which Amylin has a license under this Agreement, to lapse or become
abandoned without having first filed a substitute, HMR shall, whenever
practicable, notify Amylin of such intention at least sixty (60) days prior to
the date upon which such HMR Patent shall lapse or become abandoned, and Amylin
shall thereupon have the right, but not the obligation, to assume responsibility
for the prosecution and maintenance thereof.

               7.3.3 PATENT EXPENSES. Unless or until HMR exercises the HMR
Option, Amylin shall bear all Patent Expenses for Amylin Patents and HMR shall
bear all Patent Expenses for HMR Patents. The Parties shall share equally all
Patent Expenses for Joint Patents. Upon exercise of the HMR Option, all Patent
Expenses shall be handled as Collaboration Patent Expenses (as defined in the
Collaboration Agreement) under the provisions of the Collaboration Agreement.

        7.4 THIRD PARTY PATENT RIGHTS. Neither Party makes any representation or
warranty to the other with respect to the validity, enforceability, perfection
or dominance of any Patent or other proprietary right or with respect to the
absence of rights of Third Parties which may be infringed by the manufacture or
sale of any Product, the use of any Patent, Know-how or any other activity
contemplated by this Agreement. Each Party agrees to bring to the attention of
the other Party any patent or patent application it discovers, or has
discovered, and which relates to the subject matter of this Agreement.

        7.5    ENFORCEMENT RIGHTS.

               7.5.1  GENERAL.

                      (a) In the event a Third Party, through the actual or
        proposed manufacture, import, use, sale or offer for sale of a product
        competitive with a Product being developed or commercialized under this
        Agreement infringes or is reasonably likely to infringe ("Competitive
        Product Infringement") any Amylin Patent or Joint Patents, Amylin shall
        have the right to institute, prosecute and control any action or
        proceeding with respect to such infringement. HMR has the right to
        participate and be represented in such action by counsel of its own
        selection at its own expense. HMR agrees to be joined as a party
        plaintiff, if necessary in any such action, and to give Amylin
        reasonable assistance and any needed authority to control, file and to
        prosecute such action.

                      (b) In the event of the Competitive Product Infringement
        of any of the HMR Patents by a Third Party, HMR shall have the right to
        institute, prosecute and control any action or proceeding with respect
        to such infringement. Amylin shall have the right to participate and be
        represented in such action by counsel of its own selection at its own
        expense. Amylin agrees to be joined as a party plaintiff, if necessary
        in any such action, and to give HMR reasonable assistance and any needed
        authority to control, file and prosecute such action.

                      (c) If either Party learns or determines in good faith
        that there is or is a reasonable likelihood of Competitive Product
        Infringement of any Amylin Patents, HMR Patents, or Joint Patents by a
        Third Party, the Party first having knowledge shall promptly notify the
        other Party in writing thereof, which notice shall set forth the facts
        of such actual or potential infringement in reasonable detail. If Amylin
        or HMR, as the case may be, fails to institute and prosecute an action
        or proceeding to abate any actual


                                      20.

        infringement within a period of ninety (90) days after receiving written
        notice of actual infringement or otherwise having knowledge of the
        actual infringement, then the other Party shall have the right, but not
        the obligation, to bring and prosecute any action and the Party which
        failed to bring such action agrees to be joined as a party plaintiff in
        such action and to give the Party bringing such action reasonable
        assistance and all authority to control, file and prosecute the action
        as may be necessary; provided, however, that the Party which failed to
        bring the action shall have the right to participate and to be
        represented in any such action by counsel of its choice at its own
        expense.

                      (d) Each Party's costs of patent enforcement (including
        internal costs and expenses specifically attributable to said patent
        enforcement) and related recoveries with respect to actions brought
        under this Section 7.5.1 shall be the responsibility of such Party. Any
        amounts recovered in such action referred to in this Section 7.5.1 shall
        be apportioned between the Parties as follows: the Party bringing and
        controlling the action shall first recover from any such award an amount
        equal to the cost and expense incurred by such Party and the remainder
        shall be divided equally by the Parties.

                      (e) No settlement or consent judgment or other voluntary
        final disposition of suit under this Section 7.5.1 may be entered into
        without the joint consent of Amylin and HMR, which consents shall not be
        withheld unreasonably.

               7.5.2 SETTLEMENT OF THIRD PARTY CLAIMS FOR PRODUCTS; ROYALTY
REDUCTION. If a Third Party asserts that a patent or other right owned by it is
infringed by any Product and if following the conclusion of proceedings brought
as a result of such alleged infringement, Amylin is required to pay the Third
Party any payment of any kind for the right to sell a Product in a particular
country, the royalty rate then payable to HMR attributable only to sales in such
country shall be reduced ******* (but in no event shall the royalty rate payable
to HMR be less than ******************. The royalty rate shall return to its
previous level once Amylin has paid one-half of the payment due to the Third
Party. In the event Amylin is required to pay to the Third Party a royalty due
to an alleged infringement, then the royalty rate payable to HMR attributable
only to sales in such country shall be reduced by ******** of the royalty rate
payable to the Third Party (but no event shall the royalty rate payable to HMR
be less than *****************). Such royalty rate shall return to its previous
level once the royalty obligations to the Third Party have been satisfied. No
settlement or consent judgment or other voluntary final disposition of a suit
under this Section 7.5.2 may be entered into without the mutual consent of
Amylin and HMR.

               7.5.3 PATENT PROSECUTION RIGHTS. Notwithstanding the provisions
of Section 7.5.1, a Party shall not file or prosecute any action for
infringement of a Patent for which the other Party has the primary
responsibility if the other Party having primary responsibility is prosecuting
at least one such action for infringement of such Patent, without the agreement
of the other Party, which agreement shall not be unreasonably withheld.

                                  ARTICLE VIII

                         REPRESENTATIONS AND WARRANTIES

               Each Party hereby represents and warrants to the other Party that
this Agreement is a legal and valid obligation binding on such Party and
enforceable in accordance with its terms, subject to laws regarding bankruptcy
or insolvency generally. The execution, delivery and performance of the
Agreement by such Party does not conflict with any agreement, instrument or
understanding, oral or written, to which it is a Party or by which it is bound,
nor violate any law or regulation of any court, governmental body or
administrative or other agency having jurisdiction over it. Such Party
represents and warrants that it has not, and covenants that during the term of
the Agreement it will not, grant to any Third Party any rights which would
conflict with the rights granted to the other Party hereunder.



                                          ARTICLE IX

and accurate accounts and records of revenues, costs, expenses and payments
earned or made in connection with this Agreement and such records shall be
available for examination at the other Party's expense during such Party's
reasonable business hours for a period of five (5) years from creation of the
individual records. In addition, not more often than once each year, the other
Party may designate a firm of certified public accountant to verify the
correctness of calculations and classifications of such revenues, costs,
expenses or payments earned or made in connection with this Agreement. Any
variances in revenues, costs, expenses or payments earned or made in connection
with this Agreement discovered during such audit shall be paid within thirty
(30) days of the conclusion of the audit by the audited Party (subject to
Article XII hereof). If the audit results in a variance of more than 5% in favor

        9.2 PUBLICITY REVIEW. Subject to the provisions of this Section 9.2, no
Party shall originate any news release or Form 8-K's filed pursuant to the
Securities Exchange Act of 1934, as amended, and the rules and regulations
promulgated thereunder, relating to this Agreement or the performance hereunder
or the existence of an arrangement between the Parties (collectively, "Written
Disclosure"), without the prior prompt review and written approval of the other
Party, which approval shall not be unreasonably withheld. With regard to any
proposed Written Disclosure by Amylin, HMR shall take into consideration that
Amylin is a specialized publicly held company and as such will find it important
to provide ongoing information about Products, this Agreement and the status of
the Collaboration Agreement to investors or potential investors. The Parties
agree that should either Party make an oral disclosure and the other Party has a
concern or issue with respect to such oral disclosure, the Parties will promptly
discuss such concerns and/or issues and reasonably attempt to agree on a
modification to such oral disclosure that is mutually agreeable to the Parties.
Notwithstanding the foregoing provisions of this Section 9.2, any Party may make
any public Written Disclosure it believes in good faith is required by
applicable law or any listing or trading agreement concerning its
publicly-traded securities based upon the written advice of counsel, provided
that prior to making such Written Disclosure, the disclosing Party shall provide
the other Party with an opportunity to promptly review the proposed Written
Disclosure. To the extent that the reviewing Party reasonably requests that any
information in the proposed Written Disclosure be deleted, the disclosing Party
shall take reasonable action to avoid disclosure, where possible, including
requesting confidential treatment of such information pursuant to Rule 406 of
the Securities Act of 1933 or Rule 26b-2 of the Securities Exchange Act of 1934,
as applicable (or any other applicable regulation relating to the confidential
treatment of information).


                                    ARTICLE X

                              TERM AND TERMINATION

        10.1 TERM. This Agreement shall commence as of the Effective Date and,
unless terminated as provided herein in its entirety or with respect to certain
HMR Compounds or countries in the Territory as set forth herein, shall continue
in effect (i) if HMR does not exercise the HMR Option or the HMR Option expires
unexercised, until the date on which Amylin is no longer conducting Research and
Development with respect to an HMR Compound or marketing or selling in any
country an HMR Compound or a Product, or (ii) if HMR exercises the HMR Option,
until the date on which the Collaboration Agreement is terminated or expires
according to its terms.

        10.2 TERMINATION BY HMR FOR AMYLIN'S FAILURE TO MEET MILESTONES OR
DISCONTINUING RESEARCH AND DEVELOPMENT.

               10.2.1 TERMINATION. HMR shall have the right to terminate this

such milestones. Termination of this Agreement pursuant to this Section 10.2.1
shall be made pursuant to a written notice delivered by HMR to Amylin within
ninety (90) days after the expiration of the time period with respect to which
such notice is being delivered. Upon receipt of such written notice from HMR,
Amylin shall have a sixty (60) day period in which to cure the failure to meet
the milestone for which such notice is delivered or to continue Research and/or
Development of the HMR compounds, as the case may be. Termination pursuant to
this Section 10.2.1 shall be effective as of the sixtieth (60th) day following
delivery of the written notice to Amylin unless Amylin has cured such failure to
meet milestones or continue Research and Development, as the case may be, on or
prior to such 60th day (the "Termination Effective Date"). The termination
rights set forth in this Section 10.2.1 shall constitute HMR's sole remedy with
respect to Amylin's discontinuance of Research and/or Development on the HMR
Compounds or failure to meet any required milestones within their applicable
time periods.

               10.2.2 EFFECTS OF TERMINATION. If HMR terminates this Agreement
pursuant to this Section 10.2, the Parties shall continue to perform their
obligations under this Agreement pending the winding down of operations on the
Termination Effective Date. Upon the Termination Effective Date:

                      (a) all licenses and rights of Amylin to HMR Patents and
        HMR Know-how hereunder shall terminate in their entirety with respect to
        the HMR Compound(s);

                      (b) HMR shall receive an exclusive (even as to Amylin but
        subject to Third Party rights in existence prior to such termination)
        worldwide right and license, with the right to grant sublicenses, to all
        Amylin Patents and Amylin Know-how and Amylin's rights in any Joint
        Patents to make, have made, import, use, sell, offer for sale and have
        sold Products subject to the applicable royalty obligations set forth in
        this Agreement, and shall have the right (but not the obligation) to
        enforce the Amylin Patents and Joint Patents (in the manner contemplated
        in this Agreement in the event that Amylin does not or will not so
        enforce the Amylin Patents or the Joint Patents);

                      (c) all Confidential Information supplied by HMR to Amylin
        shall be returned to HMR, except Amylin may retain one copy of such
        Confidential Information solely for legal archive purposes; and

                      (d) Amylin shall use its best efforts to cause transfer to
        HMR of all INDs, Drug Approval Applications and Regulatory Approvals, or
        equivalent foreign filings, if any, related to the HMR Compound(s), and
        shall take such other actions and execute such other instruments,
        assignments and documents as may be necessary to effect the transfer of
        such rights hereunder to HMR.

        10.3 TERMINATION BY HMR FOR AMYLIN'S FAILURE TO COMMERCIALIZE OR MARKET
PRODUCTS IN THE TERRITORY.

               10.3.1 FAILURE TO COMMERCIALIZE IN MAJOR MARKET COUNTRIES. If
Amylin (or a sublicense of Amylin) does not commercialize a Product in a Major
Market Country within one (1) year after Regulatory Approval is obtained in such
Major Market Country, then HMR shall have the right to terminate this Agreement
with respect to such Major Market County (any such countries shall be referred
to as "Terminated Countries") and the definition of the Territory shall
thenceforth exclude such Terminated Countries. HMR shall provide written
notification to Amylin of its intent to deem a particular Major Market Country a
Terminated Country, and Amylin shall have ninety (90) days following receipt of
such written notice in which to respond to such proposed action or to cure such
failure to commercialize. If Amylin shall in good faith dispute such intention
to deem a particular country a Terminated Country, the Parties shall submit such
matter to dispute resolution as set forth in Article XII hereof.

               10.3.2 FAILURE TO MARKET. In the event Amylin fails to maintain
support of a Product in a commercially reasonable manner in a Major Market
Country, then HMR shall have the right to terminate this Agreement with respect
to such Major Market Country (and any such countries shall also be referred to
as "Terminated Countries") and the definition of Territory shall thenceforth
exclude such Terminated Countries. HMR shall provide written notification to
Amylin of its intent to deem a particular Major Market Country a Terminated
Country, and Amylin shall have ninety (90) days following receipt of such
written notice in which to respond to such proposed action or to cure such
failure to support a Product. If Amylin shall in good faith dispute such
intention to deem a particular country a Terminated Country, the Parties shall
submit such matter to dispute resolution as set forth in Article XII hereof.

               10.3.3 EFFECT OF TERMINATED COUNTRIES. If HMR terminates this
Agreement with respect to a Terminated Country, then the following provisions
shall apply:

                      (a) HMR shall receive an exclusive (even as to Amylin but
        subject to the existing rights of Third Parties) right and license in
        the Terminated Countries with the right to grant sublicenses, to all
        Amylin Patents, Amylin Know-how, Amylin's rights in any Joint Patents
        and all of Amylin's interest in trademarks in the Terminated Countries
        related to the Products, to make, have made, import, use, sell, offer
        for sale and have sold Products in the Terminated Countries, subject to
        the royalty obligations set forth below in Section 10.3.3(c), and shall
        have the exclusive right (but not the obligation) to enforce the Patents
        against Competitive Product Infringement in the Terminated Countries and
        the exclusive right (but not the obligation) to enforce the trademark
        rights related to the Products against infringers in the Terminated
        Countries.

                      (b) Amylin shall use its best efforts to cause transfer of
        all INDs, Drug Approval Applications and Regulatory Approvals, or
        equivalent foreign filings, if any, related to Products in the
        Terminated Countries to HMR, and take such other actions and execute
        such other instruments, assignments and documents as may be necessary to
        transfer the rights hereunder in the Terminated Countries to HMR.

                      (c) Amylin shall be entitled to receive royalties with
        respect to the Net Sales by HMR of Products in those Terminated
        Countries under Section 10.3.2 at a rate of ***.

        10.4   TERMINATION FOR MATERIAL BREACH.

               10.4.1 GENERAL

                      (a) Subject to the provisions of this Section 10.4, if
        either Party (the "Breaching Party") shall have committed a Material
        Breach (as defined below) and such Material Breach shall remain uncured
        and shall be continuing for a period of ninety (90) days following
        receipt of written notice thereof from the other Party (the
        "Non-Breaching Party"), then, in addition to any and all other rights
        and remedies that may be available, the Non-Breaching Party shall have
        the right to terminate this Agreement effective upon the expiration of
        such ninety (90) day period. Any such written notice of alleged Material
        Breach from the Non-Breaching Party shall include a reasonably detailed
        description of all relevant facts and circumstances demonstrating,
        supporting and/or relating to each such alleged Material Breach by the
        Breaching Party.

                      (b) If the Breaching Party, upon written notice delivered
        to the Non-Breaching Party prior to the expiration of such ninety (90)
        day period, shall assert in good faith that any such alleged Material
        Breach described in the Non-Breaching Party's notice, whether in payment
        or moneys or otherwise, was not a Material Breach, or was excused by
        reason of material failure of performance by the other Party or third
        Parties or by reason of Force Majeure (as defined in Section 13.4), or
        shall otherwise in good faith dispute such alleged Material Breach, then
        the Parties shall continue to perform under this Agreement, subject to
        all of its terms and conditions, and the matter shall be resolved
        pursuant to the provisions of Section 12.2. In such event, the
        Non-Breaching Party shall not be entitled to terminate this Agreement
        pursuant to this Section 10.4 unless and until (i) it shall be
        determined pursuant to Section 12.2 that the Breaching Party has
        committed a Material Breach and (ii) such Material Breach has not been
        cured prior to such determination pursuant to Section 12.2. To the
        extent that it is determined pursuant to Section 12.2 that the Breaching
        Party did commit a Material Breach and failed to cure the same within
        the period provided for in clause (ii) above, then the Non-Breaching
        Party may immediately terminate this Agreement and, in addition to all
        damages determined pursuant to be due and owing from the Breaching Party
        to the Non-Breaching Party under this Agreement, the Breaching Party
        shall be liable for the Non-Breaching Party's reasonable attorney's fees
        incurred in connection with resolving such matter.

                      (c) Termination of this Agreement pursuant to this Section
        10.4 shall not relieve the Breaching Party of any liability, including
        any obligation to make payments hereunder, which accrued hereunder prior
        to the effective date of such termination, nor preclude the
        Non-Breaching Party from pursuing all rights and remedies it may have
        hereunder or at law or in equity with respect to any breach of this
        Agreement nor prejudice the Non-Breaching Party's right to obtain
        performance of any obligation.

                      (d) For purposes of this Section 10.4, "Material Breach"
        shall mean the breach or failure to perform, in a material respect, a
        material obligation under this Agreement. Without limiting the foregoing
        and by way of example only, the term "Material Breach" shall be deemed
        to include the failure of either Party in a material respect to meet its
        payment or non-compete obligations. In no event shall a failure to meet
        timelines or budgets specified in any Research and Development Plan, in
        and of itself, be deemed to constitute a Material Breach, unless such
        failure is a result of acts and events or conduct that is otherwise a
        Material Breach.

        Patents and Amylin Know-how and Amylin's rights to any Joint Patents

               10.4.3 TERMINATION BY AMYLIN FOR MATERIAL BREACH. If Amylin
terminates this Agreement pursuant to the provisions of this Section 10.4 as a
Non-Breaching Party, then the following provisions shall apply:

                      (a) all licenses and rights granted by Amylin to HMR

expiration shall not relieve either Party from obligations which are expressly
indicated to survive termination or expiration of this Agreement.

                               DISPUTE RESOLUTION

        12.1 GENERAL. The Parties recognize that disputes as to certain matters
may from time to time arise during the term of this Agreement which relate to
either Party's rights and/or obligations hereunder. It is the objective of the
Parties to establish procedures to facilitate the resolution of disputes rising
under this Agreement in an expedient manner by mutual cooperation and without
resort to litigation. To accomplish this objective, the Parties agree to follow
the procedures set forth in this Article XII if and when a dispute arises under
this Agreement.

        12.2 NEGOTIATION. Either Party may, by written notice to the other, have
such dispute referred to their respective executive officers designated below or
their successors, for attempted resolution by good faith negotiations within
fourteen (14) days after such notice is received. Said designated officers are

                                  ARTICLE XIII

                                  MISCELLANEOUS

        13.1   ASSIGNMENT; BINDING EFFECT.

               13.1.1 ASSIGNMENT TO AFFILIATES. Either Party may assign any of
its rights or obligations under this Agreement in any country in the Territory
to any Affiliates; provided, however, that such assignment shall not relieve the
assigning Party of its responsibilities for performance of its obligations under
this Agreement.

               13.1.2 ASSIGNMENT TO NON-AFFILIATES. Either Party may assign any
of its rights or obligations under this Agreement or its ownership interest in
Joint Patents to a non-Affiliate only as provided in Section 7.6, in connection
with a merger or similar reorganization or the sale of all or substantially all
of its assets, or otherwise with the prior written consent of the other Party.
This Agreement shall survive any such merger or reorganization of either Party
with or into, or such sale of assets to, a Third Party and no consent for such
merger, reorganization or sale shall be required hereunder; provided, that in
the event of such merger, reorganization or sale, no intellectual property
rights of the acquiring corporation shall be included in the Patents licensed.

               13.1.3 BINDING EFFECT. This Agreement shall be binding upon and
inure to the benefit of the Parties and their respective successors and
permitted assigns of the Parties. Any assignment not in accordance with this
Agreement shall be void and of no effect.

        13.2 RESEARCH AND DEVELOPMENT ENTITIES. Either Party may assign its
rights and obligations under this Agreement to an entity or entities (e.g.,
partnership or corporation) that are specifically formed for financial purposes
and that finance research and development performed by such Party; provided,
however, that such assignment shall not relieve the assigning Party of
responsibility for performance of its obligations under this Agreement.

        13.3 CONSENTS NOT UNREASONABLY WITHHELD. Whenever provision is made in
this Agreement for either Party to secure the consent or approval of the other,
such consent or approval shall not unreasonably be withheld. Whenever provision
is made in this Agreement for one Party to object or to disapprove a matter,
such objection or disapproval shall not be unreasonably exercised.

        13.4 FORCE MAJEURE. Neither Party shall lose any rights hereunder or be
liable to the other Party for damages or losses on account of failure of
performance by the defaulting Party if the failure is occasioned by government
action, war, fire, explosion, flood, strike, lockout, embargo, act of God, or
any other similar cause beyond the control of the defaulting Party, provided
that the Party claiming force majeure has exerted all reasonable efforts to
avoid or remedy such force majeure; provided, however, that in no event shall a
Party be required to settle any labor dispute or disturbance. The foregoing
shall not affect either Party's rights hereunder to 


                                      32.
<PAGE>   38

terminate this Agreement in its entirety or with respect to certain HMR
Compounds or certain countries in the Territory pursuant to the terms hereof.

deliver such further instruments and do all such other acts, as may be necessary
or appropriate in order to carry out the purposes and intent of this Agreement.

        13.6 NO TRADEMARK RIGHTS. Except as otherwise provided herein or
otherwise agreed to in writing by the Parties, no right, express or implied is
granted by the Agreement to use in any manner the name "Amylin," "HMR" or any
other trade name or trademark of the other Party or its Affiliates in connection
with the performance of the Agreement.

        13.8 WAIVER. Except as specifically provided for herein, the waiver from
time to time by either Party of any of their rights or their failure to exercise

of any other of such Party's rights or remedies provided in this Agreement. All
such waivers shall be in writing.

        13.9 SEVERABILITY. If any term, covenant or condition of this Agreement
or the application thereof to any party or circumstance shall, to any extent, be

construed against either Party, irrespective of which Party may be deemed to
have authored the ambiguous provision.

under the laws of the State of Delaware, without regard to principles of
conflicts of law.
