effective May 28, 1993, (the "Agreement"); and

WHEREAS, COR exercised its right to extend the Research Term until
April 30, 1996; and

WHEREAS, Lilly elected to terminate its rights to develop certain
Collaboration Compounds; and

WHEREAS, under this Amendment, the parties (i) confirm their
respective rights to perform continuing research and development within the
field of Collaboration Compounds (and, with respect to certain categories of
compounds, for COR to have the right to do so in collaboration with a third
party effective immediately and Lilly to have the right to do so in
collaboration with a third party effective [*]), and (ii) allocate to each other
[*] to commercialize [*] within the category of Collaboration Compounds; and

WHEREAS, in particular, under this Amendment, COR has [*] to: (a) [*]
as to which Lilly terminated co-development under the original Agreement (as
defined below, the "Terminated Co-Development Products"), (b) [*]

1
5
[*] Specific PAI Agents (as defined below) that COR designates prior to [*] (as
defined below, the "COR Option Products"), and (c) any additional Specific PAI

to Sections 4.5a, 4.5b, 4.5c and 4.5d, at any point following the Research Term
that a Party believes a Collaboration Compound should be designated for
development, it shall submit such recommendation, together with all available
Information regarding such Collaboration Compound, to the Operating Committee
pursuant to Section 5.1 for a determination of whether such compound should be
selected for development as a

5
9
Product. If the Operating Committee does not select such compound for
development, the Party desiring to develop such compound may proceed with
development, if it desires to do so, pursuant to Section 5.10 (including the
re-offer and royalty provisions contained therein) and shall notify the other
Party if such development is discontinued. Submission by a Party of a
recommendation for development under this Section 4.5 shall preclude the other
Party from subsequently designating such Collaboration Compound for development
under Sections 4.5a, 4.5b, or 4.5c, during the time period such Collaboration
Compound is being actively developed as a Co-Developed Product or under Section
5.10.

13. Section 4.5a shall be inserted following Section 4.5 as follows:

4.5a COR INFORMATION AND REPORTS FOLLOWING THE RESEARCH TERM. At
any point before [*] that COR believes a Specific PAI Agent, [*] should be
designated for development as a COR Option Product, it shall notify Lilly and a
mutually agreed third party, in writing, of such designation. The notice to
Lilly shall include identification of the compound [*]. Subject to prior
designation of such compound for development under Section 4.5 and subject also
to Section 4.5d, this notice shall constitute a designation of such compound as
a COR Option Product. Such notice, to be effective, must be provided to Lilly
and the third party prior to or substantially contemporaneously with the [*].
COR may, at its election, undesignate [*] as a COR Option Product and
substitute one compound for each undesignated compound, provided that COR may
not undesignate a compound after the [*] of such compound. Upon a decision by
COR and/or a licensee of COR to proceed with [*] of such COR Option Product [*],
the notice provided by COR to Lilly pursuant to this Section 4.5a shall be
updated to include [*]. COR may make up to [*] compounds substitutions under
this Section 4.5a. Once a compound has been undesignated by COR, such compound
may not be subsequently designated by COR. A designation by COR of a compound
as a COR Option Product shall not itself constitute the exercise of an option
to take a license for such compound under Section 16.1(d). Such option exercise
shall occur by means of an express notice of exercise by COR, which notice must
be provided to Lilly and the third party prior to [*] of a COR Option Product
shall be deemed an option exercise by COR even if no express election

6
10
was made, in which case COR shall provide [*]. COR may exercise its option to
take a license under Section 16.1(d) only as [*]; may not [*] covered by such
exercised option; and may not exercise such option after [*].

14. Section 4.5b shall be inserted following Section 4.5a as follows:

4.5b DEVELOPMENT OF SPECIFIC NEW CHEMISTRY COMPOUNDS. Between
April 30, 1996 and [*], substantially contemporaneously with [*] by COR, COR
shall notify, in writing, Lilly and a mutually agreed third party of such
administration. The notice to Lilly shall include identification of the
compound [*], and the notice to the third party shall include identification
of the compound [*] and shall constitute perfection of COR's rights to
exclusivity for that compound under Section 16.1(e), subject to prior
designation of such compound for development under Section 4.5 and subject
also to Section 4.5d and subject to royalty obligations as set forth in
Section 13.6. Upon a decision by COR and/or a licensee of COR to proceed with
[*], the notice provided by COR to Lilly pursuant to this Section 4.5b shall
be updated to include identification of the compound [*].

15. Section 4.5c shall be inserted following Section 4.5b as follows:

4.5c DEVELOPMENT OF SPECIFIC PAI AGENTS. Commencing [*],
substantially contemporaneously with administration of the [*] by either party,
such party shall notify, in writing, the other Party and a mutually agreed
third party of such administration. The notice to the other Party shall include
identification of the compound [*], and the notice to the third party shall
include identification of the compound [*] and, subject to prior designation
of the compound for development under Section 4.5 and subject also to Section
4.5d, shall constitute perfection of the notifying party's rights to
exclusivity for that compound under Section 16.1(g) or 16.2(d), as applicable,
subject to royalty obligations as set forth in Sections 13.6, 13.19 and 13.20,
and thereafter, such compound shall be excluded from the definitions of
Collaboration Compound and Product. Upon a decision by either party to proceed
with a [*], the notice

7
11
provided by either Party to the other Party pursuant to this Section 4.5c shall
be updated to include identification of the compound [*].

16. Section 4.5d shall be inserted following Section 4.5c as follows:

4.5d RESPONSIBILITIES OF AGREED THIRD PARTY. The Parties shall
agree on a third party to receive the notices and hold the information to be
disclosed to a mutually agreed third party pursuant to Sections 4.5a, 4.5b and
4.5c. Upon receipt of a notice by a Party of [*] of a compound or other claim
to exclusivity for a particular compound under Sections 4.5, 4.5a, 4.5b or
4.5c, the third party shall determine if it has already received a notice that
such compound is being actively developed by the other Party. The third party
shall, within ten business days, communicate to both Parties whether that
compound, by name, is or is not available for the notifying Party's development
at that time. No perfection of a Party's rights to exclusivity for a compound
under Sections 16.l(d), 16.l(e), 16.l(g) or 16.2(d), shall occur without such
clearance for development by the third party. COR shall bear the expenses
incurred in connection with the third party's services under this Agreement.

17. Section 5.11 shall be inserted following Section 5.10 as follows:

5.11 TERMINATION OF CERTAIN DEVELOPMENT PROGRAMS. Lilly hereby
confirms that it has terminated its rights to develop [*] and [*] pursuant to
Section 5.9 of the Agreement.

with the following:

7.8 COMMERCIALIZATION OF NON CO-DEVELOPED PRODUCTS BY LILLY. Lilly
agrees to exercise reasonable and diligent efforts toward developing and
commercializing products developed by it under this Agreement that are not Co-
Developed Products. Other than the responsibilities of COR determined by the
Joint Research Committee in accordance with Section 4.3, such development and
commercialization shall occur at the expense of Lilly. Such development and
commercialization shall be conducted in accordance with Lilly's internal
standards with respect to matters such as development timetables, expenditures,
pricing, promotion and advertising, taking into account relevant parameters
including market size, profit margins and competition. In connection with the
development of each Lilly Product, or Product that is not a Co-Developed
Product, Lilly shall provide to COR an annual report listing the general
efforts devoted

8
12
to that product for the year including the following information: a list of the
[*] completed during the year covered by the report, a list of the [*]
commenced or ongoing during the year covered by the report and a list of the
compounds taken out of development during the year covered by the report. The
obligation to provide such reports shall begin upon the First Human Dose for
such product and shall continue until (i) the first sale of such product, or
(ii) development is terminated. If such a product is introduced commercially,
Lilly shall thereafter advise COR promptly of each application filed by its for
regulatory approval of such product in a new country, and each related
regulatory approval that is obtained. In the event COR begins to participate in
development of a Product but terminates such participation in particular
countries or overall pursuant to Section 5.8, Lilly shall thereafter provide
the reports called for in this Section 7.8.

19. Section 7.9 shall be inserted following 7.8 as follows:

7.9 COMMERCIALIZATION OF NON CO-DEVELOPED PRODUCTS BY COR. COR
agrees to exercise reasonable and diligent efforts toward developing and
commercializing products developed by it under this Agreement that are not
Co-Developed Products, including Terminated Co-Development Products, COR Option
Products, Specific New Chemistry Compounds, and COR Products. Other than the
responsibilities of Lilly determined by the Joint Research Committee in
accordance with Section 4.3, such development and commercialization shall occur
at the expense of COR. Such development and commercialization shall be
conducted in accordance with COR's internal standards with respect to matters
such as development timetables, expenditures, pricing, promotion and
advertising, taking into account relevant parameters including market size,
profit margins and competition. In connection with the development of each
Terminated Co-Development Product, COR Option Product, Specific New Chemistry
Compound, COR Product, or Product that is not a Co-Developed Product, COR shall
provide to Lilly an annual report listing the general efforts devoted to that
product for the year including the following information: a list of the [*]
completed during the year covered by the report, a list of the [*] commenced or
ongoing during the year covered by the report and a list of the compounds taken
out of development during the year covered by the report. The obligation to
provide such reports shall begin upon the First Human Dose for such product and
shall continue until (i) the first sale of such product, or (ii) development of
such product is terminated. If such a product is introduced commercially, COR
shall thereafter advise Lilly promptly of each application filed by it for
regulatory approval of such product in a new country, and each related
regulatory approval that is obtained. In the event Lilly begins to participate
in development of a Product but terminated such participating in particular

9
13
countries or overall pursuant to Section 5.8, COR shall thereafter provide the
reports called for in this Section 7.9.

20. Section 9.9 shall be inserted following Section 9.8 as follows:

9.9 cGMP COMPLIANCE AND QA AUDITS. After the Amendment Effective
Date, Lilly shall not be responsible for the manufacture of COR Option
Products, COR Products, Specific New Chemistry Compounds or Terminated
Co-Development Products. Notwithstanding the previous sentence, after the
Amendment Effective Date, Lilly shall be responsible for the manufacture of
Products developed pursuant to Section 4.5 and for the completion of
manufacturing of the bulk [*] lots that were commenced during the Research
Term. During the first [*] the Amendment Effective Date, upon written request
to Lilly and at a mutually agreeable time during normal business hours, COR
shall have the right, with respect only to such manufacture of [*] to (i) have
representatives visit Lilly's or its subcontractors' manufacturing facilities,
as applicable, (ii) review Lilly's or its subcontractors' manufacturing,
operations and assess their compliance with cGMP and quality assurance
standards, and (iii) discuss any related issues with Lilly's or its
subcontractors' manufacturing and management personnel. During the first [*] the
Amendment Effective Date, Lilly shall cooperate and cause its subcontractor to
cooperate with any inspection by the FDA or other regulatory agency, including
but not limited to any inspection prior to approval of the NDA for a Terminated
Co-Development Product containing [*].

While it is not anticipated that the FDA or other regulatory agencies
will seek to inspect or review the manufacturing of [*] by Lilly or its
subcontractors after the expiration of [*] from the Amendment Effective Date,
all parties to this agreement acknowledge the right of these agencies to do so.
In view of such potential regulatory inspection or review, Lilly agrees not to
destroy any records directly relating to the manufacturing of [*] by Lilly or
its subcontractors without first notifying COR and giving COR a reasonable
opportunity to obtain such records. In the event that such a review or
inspection is requested, COR, Lilly and Lilly's subcontractors will (i) confer
with each other with respect to the best means to comply with any such agency
requests, and (ii) use their respective best efforts to comply with such
requests. COR shall bear the reasonable direct costs incurred by Lilly in
complying with this Section 9.9.
