under this Agreement, ERS undertakes to comply with all laws pertaining to
trademarks in force at any time in the Territory.

              (d) If necessary in any country in the Territory to permit ERS to
use the Trademarks, the Company shall make application to register ERS as a
permitted user or registered user of the Trademarks and, if necessary, or if
requested by the Company, ERS undertakes to join in such application and to
take such action as may be necessary or requested by the Company to implement
such application or retain, enforce or defend the Trademarks. If necessary in
any country in the Territory to maintain the Company's rights in the
Trademarks, ERS shall enter into a registered user agreement or permitted user
agreement regulating its use of the Trademarks.

              (e) ERS acknowledges that the Company is the owner of the
Trademarks. ERS shall not at any time do, cause to be done, or permit any act
or thing inconsistent with, contesting or in any way impairing or tending to
impair such ownership. ERS agrees that all use of the Trademarks by ERS shall
inure to the benefit of and be on behalf of the Company. ERS acknowledges that
nothing in this Agreement shall give ERS any right, title or interest in the
Trademarks other than the right to use the Trademarks in accordance with this
Agreement. ERS agrees that it will not challenge the title or ownership of the
Company to the Trademarks or attack or contest the validity of the Trademarks.

              (f) The Company shall register and maintain, or cause to be
registered and maintained, in consultation with ERS, the Trademarks in the
Territory during the term of this Agreement at the Company's sole expense. If
any Party learns of any actual, alleged or threatened unauthorized use or other
infringement of the Trademarks by others in the Territory, such Party agrees to
promptly notify the other Parties of such unauthorized use or other
infringement. The Company shall use reasonable efforts to retain, enforce or
defend the Trademarks.

              (g) To the extent permitted by law, all labeling, packaging,
literature, promotional material and advertising for any Product to be
marketed, distributed or sold in any country in the Territory shall contain the
Company's name and logo with comparable prominence as the name and logo used by
ERS. To the extent practicable, or as required by applicable law to protect the
Trademarks, ERS shall include on any material bearing any Trademarks an
acknowledgement that such Trademark is the property of the Company.

         3.5 Right of First Offer to ERS Regarding the Other Compound. During
the period of time commencing on the Effective Date and ending on the First
Offer Termination Date, ERS shall have, and the Company hereby grants to ERS, a
right of first offer to enter into a partnering arrangement with the Company
for the Other Compound, as follows:

              (a) In the event that the Company is interested in seeking any
Third Party partnering arrangement with respect to the Other Compound (whether
by granting a license or other rights to a Third Party), the Company shall give
written notice thereof to ERS, together with any and all materials and relevant
information and data regarding the Other Compound that the Company has in its
possession or control. ERS shall have 30 days after receipt of such written
notice and all such information and data to decide whether or not it is
interested in entering into negotiations for such a partnering arrangement with
the Company for the Other Compound.

              (b) If ERS notifies the Company in writing within such 30-day
period that it is interested in negotiating such a partnering arrangement, the
Company shall provide ERS with written notice of its proposed material terms
and conditions of such arrangement ("Proposed Terms"). The Proposed Terms shall
include all material terms and conditions of such arrangement, including,

                                      19




Confidential treatment requested by Bristol-Myers Squibb Company, Bristol-Myers
Squibb Biologics Company and ImClone Systems Incorporated.
                                                  
without limitation, the scope of the proposed arrangement, the financial terms
and any technology or compound quid pro quo. ERS and the Company shall promptly
commence good faith negotiations (including a review of all relevant data and
information of clinical significance relating to the Other Compound), for a
period of up to 90 days after ERS receives such Proposed Terms from the
Company, in an effort to reach mutually acceptable material terms and
conditions for such arrangement, which material terms and conditions shall be
set forth in a written letter of intent ("Letter of Intent"). During such
90-day period, the Company shall not negotiate with any Third Party a potential
partnering arrangement with such Third Party with respect to the Other
Compound.

              (c) If, despite each of ERS's and the Company's good faith
efforts, the Company and ERS are not able to agree on such material terms and
conditions and do not execute a Letter of Intent by the end of such 90-day
period, ERS shall provide to the Company (within five business days) a written
notice setting forth the terms ERS will agree to for such arrangement (the "ERS
Proposed Terms"). The Company shall then have 15 days to accept or reject the
ERS Proposed Terms. If the Company declines to accept the ERS Proposed Terms
within such 15-day period, then the Company may enter into negotiations with
any Third Party regarding the Other Compound, provided, however, that the terms
and conditions of any agreement with a Third Party shall be no more favorable,
in the aggregate, to such Third Party than the ERS Proposed Terms.

         3.6 Right of First Negotiation of ERS Regarding Partnering
Transactions. At any time during the Restricted Period, ERS shall have, and the
Company hereby grants to ERS, a right of first negotiation to enter into a
partnering arrangement with the Company (including, without limitation, any
co-development, co-promotion, research and development, commercialization or
intellectual property license agreement, joint venture, partnership, or other
partnering relationship) involving compounds or products not directly relating
to the Other Compound, to the extent involving the out-licensing of any of
intellectual property or know-how owned by the Company or to which the Company
has an exclusive license ("Partnering Relationship").

              (a) In the event that the Company is interested in establishing a
such Partnering Relationship with a Third Party, the Company shall give written
notice thereof to ERS, together with any and all materials and relevant
information and data regarding the subject matter of such proposed Partnering
Relationships that the Company has in its possession or control.

              (b) With respect to each such Partnering Relationship, ERS shall
have 90 days after receipt of such written notice and all such information and
data to enter into a non-binding heads of agreement with the Company containing
the proposed material terms of an agreement regarding such Partnering
Relationship. During such 90-day time period, the Company shall not negotiate
such a Partnering Relationship with any Third Party. In the event that ERS and
the Company do not enter into a non-binding heads of agreement as aforesaid,
the Company shall be free to proceed to negotiate with Third Parties as it
deems appropriate without any further obligation to ERS.

         3.7 Negotiation of Services. As soon as reasonably practicable after
the Effective Date, the Parties will negotiate in good faith the Company's
access to ERS's and BMS's research and development services, including
medicinal chemistry, high throughput screening, genomics, etc., and the extent
to which and terms on which such services will be made available to the
Company.

         3.8 Restrictions on Competing Products. Except as permitted by this
Section 3.8, during the period from the Effective Date to the seventh
anniversary of the Effective Date, each Party agrees not to, and to cause its
Affiliates not to, directly or indirectly, develop or commercialize a Competing
Product in any country in the Territory. In the event that a Party (an
"Acquiring Party") proposes to develop or commercialize a Competing Product or
purchases or otherwise takes control of a Third Party which has developed or
commercialized (and is continuing to produce or sell), or is developing

or commercializing, a Competing Product (directly or indirectly), in any such
case within the Territory, the Acquiring Party shall, at its option, either:

              (a) divest, or cause its applicable Affiliate to divest, the
Competing Product within 12 months after such event; or

              (b) offer to the Company (in the case of BMS or ERS) or ERS (in
the case of the Company), (the "Non-Acquiring Party"), the right to: (i)
participate in 50% of the Acquiring Party's rights and obligations in
connection with the development and commercialization of the Competing Product;
or (ii) acquire 50% of the Acquiring Party's interest in the Competing Product
at a valuation which is in proportion to the price paid by the Acquiring Party
for the Competing Product. In such event, such Parties shall conduct good faith
discussions regarding the terms of such arrangement. In the event that such
Parties do not reach agreement on such terms, or the Non-Acquiring Party
declines to participate or acquire such an interest in the Competing Product,
then the Acquiring Party shall be required to divest, or cause its applicable
Affiliate to divest, the Competing Product within 12 months after such event.

         3.9 The Company's Right to Develop and Market Products.

              (a) In the event that the Company believes that ERS is not
adequately performing its obligations and responsibilities under the relevant
Clinical Development Plan or the Marketing Plan, the Company shall provide ERS
with written notice of such claim including specification of the respects in
which the Company believes ERS is not meeting such obligations and
responsibilities with reasonable particularity. The PDC or the JCC, as the case
may be, shall promptly meet to discuss such claims. If the PDC or the JCC, as
the case may be, does not reach a consensus decision, then the matter shall be
referred to the JEC for resolution, provided that Sections 2.1(d)(ii), (iii)
and (iv) shall not apply with respect to such matter. If the JEC does not reach
consensus decision on the matter, then the Company may submit the matter to
arbitration pursuant to the Accelerated Arbitration Provisions set forth in
Section 16.13(b).

              (b) If a determination is made pursuant to Section 3.9(a), by the
PDC, the JCC, the JEC or the arbitrators, as the case may be, that ERS has
failed to adequately perform such obligations and responsibilities, then the
Company may perform such obligations and responsibilities to the extent it
reasonably deems appropriate. The Company's performance of such obligations and
responsibilities pursuant to this Section shall be reasonably consistent with
the scope of performance of such obligations and responsibilities contemplated
to be performed by ERS in the relevant Clinical Development Plan or Marketing
Plan, as the case may be.

              (c) Provided that the performance by the Company is in accordance
with the scope of such performance contemplated by Section 3.9(b), ERS shall
reimburse the Company for all of the Company's Development Costs, Distribution
Costs, Sales Costs, Marketing Costs and Other Operating Income/Expense, as the
case may be, incurred by the Company with respect to such actions. In addition,
if the Company elected to commence performance of such obligations and
responsibilities prior to a determination being made pursuant to Section
3.9(a), and such determination is that ERS has failed to adequately perform
such obligations and responsibilities, then ERS shall reimburse the Company for
all such costs incurred by the Company prior to the date of such determination,
but only for such costs incurred by the Company that were necessary to satisfy
the performance obligations and responsibilities that it is determined ERS
failed to adequately provide.

              (d) If such failure to perform is in connection with ERS's
obligations and responsibilities in Japan, then ERS shall have the right to
include any amount paid to the Company pursuant to this Section as Development
Costs, Distribution Costs, Sales Costs, Marketing Costs and/or Other Operating
Income/Expense, as the case may be, for purposes of calculating Operating
Profit or Loss.

              (e) In no event shall ERS be obligated pursuant to this Section
to reimburse the Company for any costs incurred by the Company pursuant to this
Section 3.9 unless: (i) the relevant Committee reaches a consensus decision, or
the arbitrators find, that ERS failed to adequately perform such obligations
and responsibilities; or (ii) ERS otherwise consents in writing. The rights of
the Company under this Agreement shall not be affected in any way by the
Company's waiver or failure to take action pursuant to this Section 3.9. Any
rights provided to the Company pursuant to this Section shall be in addition to
any other rights or remedies available to the Company under this Agreement, at
law or in equity.

         4.3 Scope of Clinical Development Plans and Clinical Budget.

              (a) A clinical budget containing the budget for the conduct of
the Clinical Development Plans for the development of Compounds and Products
for calendar years 2001 through and including 2017, on a calendar
year-by-calendar year basis, is attached to this Agreement as Exhibit 4.3(A)
(such budget, as modified from time to time pursuant to this Agreement, the
"Clinical Budget").

              (b) A Summary Clinical Development Plan for calendar years 2001
through 2004 is attached to this Agreement as Exhibit 4.3(B). As soon as
reasonably possible after the Effective Date, the PDC shall meet to develop,
finalize and approve the definitive clinical development plan for the Compounds
and the Products for calendar years 2001 through 2004 based on the Summary
Clinical Development Plan for such period. Such Clinical Development Plan shall
include: (i) a plan for the rapid and orderly transition, after the BLA Filing
Date, of those clinical and other studies ongoing with respect to the Compounds
and Products which are identified in the initial Clinical Development Plan as
being transferred to ERS from the Company's sole control to the control of ERS
and the Company, as determined by the PDC in conformity with all applicable
regulatory requirements and consistent with Section 4.1; (ii) the allocation
and transition of regulatory strategy and responsibility for the Products;
(iii) the research and development activities of any or all of the Parties
under this Agreement for the development of Compounds and Products for calendar
years 2001, 2002, 2003 and 2004, including the allocation of resources between
the Company and ERS, which shall be consistent with the Clinical Budget for
such period; (iv) "go/no go" decision criteria for each stage of development of
a Product; (v) target Product profiles; and (vi) timelines for scientific,
medical, regulatory and other activities to be undertaken by the Parties for
the purpose of obtaining Registrations for the Products in each country in the
Territory, providing marketing support and developing new indications and
formulations for the Products. Every Clinical Development Plan for the relevant
period shall comprise two components: (1) those clinical studies required for
approval of new indications, other labeling changes or for any other purpose
under an IND (e.g., Phase I through Phase III studies (the "Registrational
Studies"); and (2) those studies undertaken post-launch which are not
Registrational Studies (e.g., Phase IV studies) ("Non-Registrational Studies").
The PDC shall use all commercially reasonable efforts to finalize and approve
the initial Clinical Development Plan no later than 90 days after the Effective
Date.

              (c) Prior to Registration in any country in the Territory, the
Parties intend that the Company will be primarily responsible for implementing
the regulatory strategy for the Products in such country developed by the PDC.
The Parties intend that ERS will be primarily responsible for regulatory
activities in a country in the Territory after Registration in such country,
comprising regulatory compliance, worldwide safety surveillance, adverse event
reporting and all other necessary support services.

              (d) At least 12 months prior to the end of the last calendar year
for which a Clinical Development Plan has been approved (i.e., prior to the end
of 2004, 2008 and 2012, respectively), the PDC shall develop, finalize and
approve a summary clinical development plan for the Compounds and the Products
for the four (or, in the case of the last such period, five) calendar years
next succeeding such calendar year, comparable in scope and detail to the
Summary Clinical Development Plan attached as Exhibit 4.3(B) (i.e., for the
period from 2005 through and including 2008, 2009 through and including 2012,
2013 through and including 2017) (each such approved summary clinical
development plan is a Summary Clinical Development Plan).

              (e) At least six months prior to the end of the last calendar
year for which a Clinical Development Plan has been approved (i.e., prior to
the end of 2004, 2008 and 2012, respectively),

the PDC shall develop, finalize and approve a definitive clinical development
plan for the Compounds and the Products for the four calendar years (or, in the
case of the last such period, five calendar years) next succeeding such
calendar year, containing the information described in Section 4.3(b)(ii)
through (vi) for the relevant period (i.e., for the period from 2005 through
and including 2008, 2009 through and including 2012, 2013 through and including
2017) based on the Summary Clinical Development Plan for such period (each such
approved definitive clinical development plan is a Clinical Development Plan);
provided, however, that the Clinical Budget for each such calendar year shall
be no less than the amount set forth in the Clinical Budget attached as Exhibit
4.3(A) with respect to such calendar year, except that:

                   (i) if Net Sales of Products for the calendar year
immediately preceding such calendar year are less than the [**] for the
immediately preceding calendar year, but more than the [**] for the immediately
preceding calendar year, then the Clinical Budget for the calendar year in
question shall be no less than an amount equal to [**] of the amount set forth
in the initial Clinical Budget for the calendar year in question, determined on
a [**] based upon the actual [**] for the calendar year immediately preceding
the calendar year in question and the [**] and [**], such that if the actual
Net Sales were equal to the Low Case Projections, the amount would be equal
[**] and if [**] were equal to the [**], the amount would be equal to [**] or

                   (ii) if Net Sales of Products for the calendar year
immediately preceding such calendar year are less than the [**] for the
immediately preceding calendar year, then the Clinical Budget for the calendar
year in question shall be no less than an amount equal to [**] of the amount
set forth in the initial Clinical Budget for the calendar year in question.

              (f) As of the Effective Date, each of the Parties believes that
the Clinical Budget provides for sufficient funds to complete the execution of
the Clinical Development Plans that are to be developed by the Parties in
accordance with this Section 4.3. ERS shall provide sufficient funds to
complete the execution of the Clinical Development Plans provided they are
developed in accordance with this Section 4.3 (even if such funding is in
excess of the Clinical Budget). Any change to any Clinical Development Plan
after the development thereof in accordance with this Section 4.3 must be
approved by the PDC, provided that any such change that (i) alters the number
of patients being studied under the Clinical Development Plan or the type
and/or phase of such studies, or (ii) increases the amount of funding necessary
to complete a Clinical Development Plan as a result of any change to (A) the
timing of entry of such patients into studies under such Clinical Development
Plan, or (B) the procedures to be conducted in such studies, in each such case
shall relieve ERS of the funding obligation set forth in the immediately
preceding sentence with regard to such revised Clinical Development Plan only
to the extent that such revised Clinical Development Plan requires funding
which exceeds the Clinical Budget (after taking into account any increase in
the Clinical Budget in accordance with Sections 2.1(d)(ii) or (iii)).

         4.4 Transition of Clinical Studies. As soon as practicable after the
BLA Filing Date, and consistent with the transition plan adopted by the PDC and
contained in the initial Clinical Development Plan, the Company shall
transition such clinical and other studies ongoing with respect to the Products
which have been identified in such Clinical Development Plan as being
transferred to ERS in such transition plan from the Company's sole control to
the control of the Party(ies) set forth in the initial Clinical Development
Plan. Thereafter, ERS shall be primarily responsible for performing such
studies designated therefor in the Clinical Development Plans through
completion, and the Company shall be primarily responsible for performing such
studies designated therefor in the Clinical Development Plans through
completion. During the transition period, the Company shall continue to be
involved in the ongoing clinical studies in order to assure an orderly transfer
of responsibility.

         4.5 Conduct of Clinical Development Plans. Under the auspices of, and
subject to review and approval by, the PDC, the Parties shall have the
following responsibilities relating to the conduct of the Clinical Development
Plans:

              (a) Each of ERS and the Company shall be responsible for the
preparation of all protocols and the conduct of all Registrational Studies and
Non-Registrational Studies for which such Party is designated as the Party
responsible for such studies in the Clinical Development Plans. Each such Party
shall submit all protocols for Registrational Studies to the PDC and, in the
case of the Non-Registrational Studies, to the JCC, for its or their approval,
as the case may be.

              (b) Each of ERS and the Company shall be responsible for
preparing all Regulatory Applications necessary or desirable to register the
Products in all countries in the Territory for which such Party is designated
as the Party responsible for such preparation in the Clinical Development
Plans. The Company shall be responsible for filing all Regulatory Applications
(whether prepared by the Company or ERS) and, thereafter, to conduct all
communications with the Regulatory Authorities during the registration process
(provided that, if ERS is the responsible Party for the preparation of such
Regulatory Application, it will work with the Company with respect to all such
regulatory activities). Each such Party shall submit all proposed filings to
the PDC for its approval. The other such Party shall provide all technical data
and support necessary to assist the responsible Party to prepare such

4.7 IT Support. From and after the Effective Date, ERS shall provide software and technical assistance to the Company which are reasonably necessary to enable the Company to fulfill its obligations under this Agreement by allowing the Company's information systems to communicate and exchange data with ERS's and BMS's information systems to a degree and in a manner mutually agreed upon by the Parties. Such software and technical assistance will enable secure information flow among the Parties with respect to clinical, regulatory, manufacturing, marketing and sales information. It is understood that such software and technical assistance shall not include providing any hardware necessary for the Company to permit such information flow or incurring the costs associated with such hardware by ERS. ERS and BMS shall be responsible for all costs they incur in connection with providing the foregoing software and technical assistance to the Company, which 26 Confidential treatment requested by Bristol-Myers Squibb Company, Bristol-Myers Squibb Biologics Company and ImClone Systems Incorporated. shall include, without limitation, ERS's and BMS's internal costs of providing information technology personnel to provide such software and technical assistance and all applicable allocable overhead. Each of the Parties shall be responsible for their respective internal information technology maintenance costs associated with or arising from the foregoing, which shall include, without limitation, each such Party's internal costs of providing information technology personnel to provide such maintenance and all applicable allocable overhead. This Section 4.7 is not intended to address software or hardware upgrades unilaterally undertaken by the Company without ERS's consent after the foregoing communication and data exchange systems have been established. In the event that the Parties cannot agree with respect to any of the foregoing, such matter shall be referred to the relevant Committee for resolution. 4.8 Delay of Initial Regulatory Filing.

As used in this Section 4.8, a material delay is a delay arising from a requirement set forth by the FDA that the Company conduct additional clinical studies not conducted in connection with the submission of the Initial Regulatory Filing. In the event of a material delay, the PDC shall apply its sound scientific, commercial and regulatory judgment with all deliberate speed to determine whether or not it is in the best interest of both of ERS and the Company to go forward with the conduct of any additional clinical studies required by the FDA. Upon reaching such determination, the PDC shall make a formal recommendation of its conclusions to the JEC and shall await direction from the JEC regarding what, if any, further action is to be taken with respect to such matters. Upon receiving the approval of the JEC to undertake the additional clinical studies required by the FDA, the PDC shall be authorized to, and is hereby directed to, redirect (without increasing) the existing overall Clinical Budget as necessary to undertake such studies and to cause such studies to be undertaken. 4.9 Suspension of Clinical Development Activities. Any Party shall have the right to immediately suspend the relevant clinical development activities with respect to a Product or Compound for a particular indication, formulation or dosage form in the event that such Party, in good faith, determines that there exists significant and urgent concerns relating to patient safety with respect to such clinical studies. The Party making the determination to suspend such clinical activities shall notify the other Parties in writing immediately of any such suspension and the reasons therefor. The PDC shall then promptly determine what actions should be taken with respect to such clinical activities.

In order to exercise the Co-Promotion Option, the Company must give ERS written notice of such exercise at least six months prior to the date the Company intends to begin its co-promotion activities. (b) The Company will be included in, and be allowed to participate in, all promotional activities being conducted by ERS pursuant to the then current Marketing Plan, 29 Confidential treatment requested by Bristol-Myers Squibb Company, Bristol-Myers Squibb Biologics Company and ImClone Systems Incorporated. including participation in symposia, key opinion leader events, and the like.

The JCC shall promptly meet to discuss such claims and to determine whether or not such a Co-Promotion Problem has occurred. If the JCC does not reach a consensus decision, then the matter shall be referred to the JEC for resolution, provided that Sections 2.1(d)(ii), (iii) and (iv) shall not apply with respect to such matter. If the JEC does not reach consensus decision on the matter, then ERS may submit the matter to arbitration pursuant to the Accelerated Arbitration Provisions set forth in Section 16.13(b).

The Auditing Party shall bear the full cost of the performance of any audit requested by the Auditing Party except as hereinafter set forth. If, as a result of any inspection of the books and records of the Audited Party and/or its Affiliates, it is shown that payments made by ERS to the Company under this Agreement were less than the amount which should have been paid, then ERS shall make all payments required to be made to eliminate any discrepancy revealed by said inspection within 30 days after the Company's demand therefor. Furthermore, if the payments made were less than 95% of the amount that should have been paid during the period in question, ERS shall also reimburse the Company for the reasonable costs of such audit; provided, however, that no such reimbursement of such audit costs shall be made in the event such audit determines that, in the period in question, the Company misstated the financial data it reported to ERS pursuant to Section 7.1 and the Financial Appendix by such an amount as to cause an increase in the underpayment by ERS great enough to trigger the threshold set forth above, without which ERS would be within such threshold. In the event that the audit shows that an overpayment has been made by ERS, such amounts shall be deducted from Distribution Fees owed to the Company. If such overpayment amounts have not been settled by such deductions from Distribution Fees within one year from the date originally overpaid, then the Company shall make all payments required to be made to ERS to eliminate any such overpayment. Furthermore, if (i) the overpayment made was more than 105% of the amount that should have been paid during the period in question and (ii) the costs invoiced by the Company were more than 105% of the audited costs during the period in question, then the Company shall also reimburse ERS for the reasonable costs of such audit; provided, however, that no such reimbursement of such audit costs shall be made in the event such audit determines that, in the period in question, ERS misstated the financial data it reported to the Company pursuant to Section 7.1 and the Financial Appendix by such an amount as to cause an increase in the costs invoiced by the Company and/or the overpayment by ERS great enough to trigger the thresholds set forth above, without which the Company would be within such thresholds. 7.7 No Non-Monetary Consideration for Sales. Without the prior written consent of the Company, ERS and its Affiliates shall not accept or solicit any non-monetary consideration of the sale of the Products. Subject to the applicable oversight and approval responsibilities of the PDC and the JCC set forth in Sections 2.3(b)(vii) and 2.4(b)(vii), the use by ERS and its Affiliates of a commercially reasonable amount of the Products for promotional sampling, compassionate use and indigent care shall not violate this Section 7.7. 7.8 Taxes. In the event that ERS is required to withhold any tax to the tax or revenue authorities in any country in the Territory regarding any payment to the Company due to the laws of such country, such amount shall be deducted from the payment to be made by ERS, and ERS shall promptly notify the Company of such withholding and, within a reasonable amount of time after making such deduction, furnish the Company with copies of any tax certificate or other documentation evidencing such withholding. Each Party agrees to cooperate with the other Parties in claiming exemptions from such deductions or withholdings under any agreement or treaty from time to time in effect. 34 Confidential treatment requested by Bristol-Myers Squibb Company, Bristol-Myers Squibb Biologics Company and ImClone Systems Incorporated. 8. MANUFACTURE AND SUPPLY. 8.1 Supply Obligations. Under the auspices of, and subject to review and approval by, the JMC, and except as mutually agreed by ERS and the Company, the Parties shall have the following responsibilities relating to the manufacture and supply of API and Finished Products: (a) Commencing on the Effective Date, and thereafter during the term of this Agreement, the Company (or its Affiliates) shall be responsible for the manufacture or supply of all requirements of API for clinical and commercial use in the Territory pursuant to this Agreement. (b) Prior to expiration, termination or assignment (pursuant to Section 8.9) of any existing agreement between the Company and a Third Party Manufacturer for the manufacture of Finished Products, the Company shall be the Party responsible for processing the API into Finished Products pursuant to such agreement. Commencing upon the expiration, termination or assignment (pursuant to Section 8.9) of any existing agreement between the Company and a Third Party Manufacturer for the manufacture of Finished Products, ERS shall become and thereafter shall remain the Party responsible for processing the API into Finished Products. 8.2 Supply of API; Processing of Finished Product. (a) Commencing on the commercial launch of Product and thereafter during the term of this Agreement, subject to the terms and conditions of this Section 8, the Company shall supply ERS with all of ERS's requirements for API for commercial use in the Territory pursuant to this Agreement (which shall be deemed to include all of the requirements of ERS's Affiliates), and ERS shall purchase from the Company all of such requirements for API. ERS shall place orders for the requirements of its Affiliates, and either have the Company ship directly to such Affiliates or to ERS for its reshipment to such Affiliates. (b) Except to the extent that the Company is responsible for processing API into Finished Products pursuant to Section 8.1(b), ERS (or its Affiliates) shall be responsible for processing the API into Finished Product, including, without limitation, all product labeling and other package inserts and materials required by the applicable Regulatory Authorities. The responsible party shall use commercially reasonable efforts to ensure that all services, facilities and goods used in connection with such manufacture comply with the applicable Manufacturing Standards in effect from time to time.

In order to facilitate manufacture of the API and the Finished Products, as ERS and the Company deem appropriate, such Parties shall cooperate in good faith with Third Parties to establish Specifications and Manufacturing Standards for this Agreement that conform to the extent practicable to the specifications and standards applicable to the Company's manufacture of the API and products containing the API for such Third Parties, and the Company shall use all reasonable efforts to cause such Third Parties to do the same. (d) The Parties intend that the Company will use BMS's Hopewell facility to provide certain services in connection with establishing a non-commercial supply of API. As soon as reasonably practicable after the Effective Date, BMS and the Company will negotiate in good faith the Company's use of BMS's process development and analytical services at BMS's Hopewell facility for the support of pre-clinical and clinical supplies of API for use in the development of Products, and the extent to which and terms on which such services will be made available to the Company. 35 Confidential treatment requested by Bristol-Myers Squibb Company, Bristol-Myers Squibb Biologics Company and ImClone Systems Incorporated. 8.3 Forecasts. Commencing 12 months prior to the anticipated commercial launch of the Product in any country in the Territory, no later than 180 days prior to the first day of each calendar quarter ("Q1"), ERS shall provide the Company with a non-binding (except with respect to Q1), good faith rolling forecast of estimated quantities in kilograms and anticipated delivery schedules for API for the following 12-month period (i.e., Q1 and the next three calendar quarters ("Q2," "Q3" and "Q4," respectively)), by calendar quarters. The quantity indicated for Q1 shall be considered a firm order, in accordance with Section 8.4. Such forecasts shall be revised and updated quarterly, including firm orders for the next succeeding quarter. 8.4 Orders for API. (a) Together with each forecast provided under Section 8.3 (the "Current Forecast"), ERS shall place its firm order on a quarterly basis with the Company, setting forth kilograms, delivery dates and shipping instructions with respect to each shipment of API for delivery in Q1. The Company shall accept such orders from ERS, subject to the other terms and conditions of this Agreement, to the extent such quantity of API is: (i) no more than the least of: (A) the quantity thereof reflected in the Current Forecast for Q1; (B) 110% of the quantity thereof reflected for Q2 in the forecast that next preceded the Current Forecast; and (C) 125% of the quantity thereof reflected for Q3 in the forecast that next preceded the forecast referred to in clause (i)(B); and (ii) no less than the greatest of: (A) the quantity thereof reflected in the Current Forecast for Q1; (B) 90% of the quantity thereof reflected for Q2 in the forecast that next preceded the Current Forecast; and (C) 75% of the quantity thereof reflected for Q3 in the forecast that next preceded the forecast referred to in clause (ii)(B). ERS's orders shall be made pursuant to purchase orders which are in a form mutually acceptable to the ERS and the Company, to the extent that such form is not inconsistent with the terms of this Agreement. (b) The Company shall not be obligated to accept orders for Q1 to the extent the quantity of API ordered exceeds the foregoing limitations, but shall use good faith efforts to fill such orders for such excess quantities from available supplies. In the event that the Company, despite the use of good faith efforts, is unable to supply such excess quantities to ERS, such inability to supply shall not constitute a breach of the Company's obligations under this Section 8 or a Short-Term Inability to Supply or Long-Term Inability to Supply. The Company shall use all reasonable efforts to notify ERS within ten days after receipt of an order of the Company's ability to fill any amounts of such orders in excess of the quantities that the Company is obligated to supply. ERS shall notify the Company as soon as possible of an increase in ERS's requirements for API materially in excess of the limits set forth in Section 8.4(a). (c) In the event that ERS submits orders for API with respect to any Q1 for less than the minimum quantity of API that ERS is required to purchase under this Section 8, the Company nevertheless shall have the right to supply and ship to ERS (in accordance with the shipping instructions most recently supplied by ERS), and ERS shall have the obligation to purchase and accept from the Company, such minimum quantity of API. ERS shall notify the Company as soon as possible of a decrease in ERS's requirements for API materially below the limits set forth in Section 8.4(a). In the event of such a decrease, the Company shall use all reasonable efforts, but shall not be required, to reduce accordingly the orders for API that the Company has placed with its Third Party Manufacturers or to allocate to other purchasers API that ERS would have purchased but for such decrease. 8.5 Delivery. With respect to exact shipping dates, the Company shall use all reasonable commercial efforts to ship or cause to be shipped quantities of API that the Company is obligated to supply pursuant to Section 8.4 on the dates specified in ERS's purchase orders submitted and accepted in accordance with Section 8.4. Notwithstanding any Incoterm that may be specified on 36 Confidential treatment requested by Bristol-Myers Squibb Company, Bristol-Myers Squibb Biologics Company and ImClone Systems Incorporated. ERS's API purchase order, all API to be delivered pursuant to this Agreement shall be delivered in accordance with this Section 8.5, suitably packed in bulk containers for shipment, and marked for shipment to the final destination point indicated in ERS's purchase order. The shipping packaging used in connection with such API deliveries shall be in accordance with cGMP with respect to protection of the API during transportation, taking into consideration the mode(s) of transport ERS has elected to use for each such shipment, the final destination point of each such shipment and reasonable expectations regarding shipment time duration and possible delays associated therewith. Transportation of API may be made by rail, road, air, sea, inland waterway or by a combination of such modes of transport. The Company will deliver or cause to be delivered all API, cleared for export (if applicable based on the final destination point and expected travel route indicated in ERS's purchase order), to the carrier nominated by ERS at a point selected by the Company. If such delivery occurs at the Company's or a Third Party's premises, the Company or such Third Party shall be responsible for loading. If delivery occurs at any other place, the Company or such Third Party shall not be responsible for unloading. If ERS nominates a Person other than a carrier to receive the API, the Company shall be deemed to have fulfilled its obligation to deliver the API when the API is delivered to that Person. Title and risk of loss shall transfer to ERS upon delivery to the carrier or Person designated by ERS. 8.6 Purchase Price. (a) The purchase price for all API supplied by the Company to ERS pursuant to this Section 8 for commercial use in North America shall be the Company's Fully Burdened Manufacturing Cost for such API plus a mark-up of 10%; provided, however process development, process improvement, scale-up, recovery, and qualification lots costs (although components of Fully Burdened Manufacturing Cost) shall not be subject to the mark-up of 10%. (b) For all API supplied by the Company to ERS pursuant to this Section 8 for commercial use in Japan, the Company's Fully Burdened Manufacturing Cost for such API shall be included in the calculation of Operating Profit or Loss, pursuant to the Financial Appendix. Similarly, ERS's Fully Burdened Manufacturing Cost for the processing API into Finished Product for commercial use in Japan shall be included in the calculation of Operating Profit or Loss, pursuant to the Financial Appendix. (c) For API supplied to ERS for the clinical studies and for commercial use in North America, the Company shall submit invoices to ERS for API promptly after shipment. Payments shall be made by ERS within 60 days after ERS's receipt of the invoice. ERS has no obligation to pay for any shipment of API that (i) ERS and the Company agree does not to meet the Specifications and/or Manufacturing Standards, or (ii) in accordance with Section 8.8(b), ERS has found not to meet the Specifications and/or Manufacturing Standards while such findings have not been contradicted by independent laboratory testing. Upon the Company's receipt of a notice from ERS claiming that a shipment of API does not meet the Specifications and/or applicable Manufacturing Standards, the time period for payment of such shipment or such batch shall toll until such time as such non-conformity questions regarding such shipment or such batch are resolved in accordance with Section 8.8. All relevant terms of Section 7 with respect to payments of Distribution Fees shall apply to the payment of invoices for the supply of API. (d) Once the Company begins manufacturing API itself, it shall use its commercially reasonable efforts to reduce the Fully Burdened Manufacturing Cost of manufacturing API itself to an amount equal to or less than [**] before the end of calendar year [**]. The foregoing sentence shall apply only to API for the initial Product, and not to any other Products or line extensions. If, in order to achieve the reduction referred to in the first sentence of this Section 8.6(d), the Company reasonably determines that it must change the cell line and/or manufacturing process for the Product, 37 Confidential treatment requested by Bristol-Myers Squibb Company, Bristol-Myers Squibb Biologics Company and ImClone Systems Incorporated. the JMC shall approve such change and ERS shall assume all costs of any testing, qualification, scale-up, regulatory filings, and additional clinical trials which are reasonably necessary to support such changes in addition to, and not as part of, the Development Costs assumed elsewhere in this Agreement. In the event that the Company does not achieve the target Fully Burdened Manufacturing Cost set forth in the first sentence of this Section 8.6(d), any excess of Fully Burdened Manufacturing Cost above such target cost shall be [**] by ERS and the Company, after the end of calendar year [**]. 8.7 Conformity; Specifications; Quality Control (a) All quantities of API supplied by the Company pursuant to this Section 8 will comply in all material respects with the Specifications and applicable Manufacturing Standards and shall adhere in all material respects to all applicable governmental laws and regulations relating to the manufacture, sale and shipment of each shipment of API at the time it is shipped by the Company hereunder. (b) Changes to the Specifications shall be made only by the JMC. (c) The Company shall conduct, or cause to be conducted, quality control testing of API prior to shipment, in accordance with the Specifications and applicable Manufacturing Standards as are in effect from time to time and such other quality control testing procedures adopted by the JMC from time to time (collectively, the "Testing Methods"). Initially and until decided otherwise by the JMC, the Testing Methods shall include all FDA required release testing and the Company shall undertake all such tests. The Company shall retain records pertaining to such testing. Each shipment of API hereunder shall be accompanied by a certified quality control protocol and certificate of analysis for each lot of API therein as well as such customs and other documentation as is necessary or appropriate. (d) ERS shall have the right, at reasonable times and upon reasonable notice, to inspect all facilities at which API is manufactured pursuant to this Section 8 for compliance with cGMP, subject to existing agreements with Third Party Manufacturers. (e) All units of Finished Product manufactured pursuant to this Agreement will comply in all material respects with the applicable Manufacturing Standards and specifications for Finished Products determined by the JMC and shall adhere in all material respects to all applicable governmental laws and regulations relating to the manufacture, sale and shipment of each Finished Product at the time it is manufactured and distributed hereunder. (f) The Party responsible for processing the API into Finished Products (either ERS or the Company to the extent that the Company is responsible for processing API into Finished Products pursuant to Section 8.1(b)) shall conduct, or cause to be conducted, quality control testing of each Finished Product prior to shipment, in accordance with the applicable Manufacturing Standards and specifications for Finished Products determined by the JMC, as are in effect from time to time and such other quality control testing procedures adopted by the JMC from time to time. Such Party shall retain records pertaining to such testing. 8.8 Acceptance/Rejection; Interim Replacement. (a) ERS may test or cause to be tested API supplied under this Section 8 in accordance with ERS's customary procedures within 30 days of its receipt at ERS's plant or that of 38 Confidential treatment requested by Bristol-Myers Squibb Company, Bristol-Myers Squibb Biologics Company and ImClone Systems Incorporated. its designee. ERS or its designee shall have the right to reject any shipment of API made to it under this Agreement that does not meet the Specifications and applicable Manufacturing Standards in any material respects when received by it at such destination when tested in accordance with the Testing Methods. All claims by ERS of non-conforming API shall be deemed waived unless made by ERS in writing and received by the Company within such 30-day period. (b) All claims of non-conforming API shall be accompanied by a report of analysis (including a sample of the API from the batch analyzed) of the allegedly non-conforming API that shall have been made by ERS or its designee, using the Testing Methods. The Company shall promptly undertake its own analysis of such sample after receiving such claim and report from ERS. If, after its own analysis, the Company does not confirm such non-conformity, the JMC shall agree to retest the shipment or otherwise in good faith attempt to agree upon a settlement of the issue. In the event that the JMC cannot resolve the issue, the JMC shall submit the disputed API to an independent testing laboratory, to be agreed upon by the JMC, for testing in accordance with the Testing Methods. Notwithstanding Section 16.13, the findings of such laboratory shall be binding on the Parties, absent manifest error. Expenses of such independent testing shall be borne by either ERS or the Company depending on which such Party is adversely affected by such findings. In the event that any API shipment or batch thereof is ultimately agreed or found not to meet the Specifications and/or applicable Manufacturing Standards, the Company agrees to replace such shipment or batch with conforming API and pay for all reasonable out of pocket expenses incurred by ERS and the Company in connection with shipping and/or storing such replacement API and storing the non-conforming API. Such replacement shipment of API shall be treated as a new, additional shipment of API (that will be separately invoiced by the Company) for all purposes, including measuring its conformity to the Specifications and applicable Manufacturing Standards and ERS's payment for such additional shipment. ERS shall return any such rejected shipment to the Company if so instructed by the Company, at the Company's expense. In the event that any API shipment or batch thereof is ultimately agreed or found to meet the Specifications and applicable Manufacturing Standards, ERS shall accept and pay for such shipment or batch in accordance with Section 8.6(c). (c) Within 30 business days following December 31st of each calendar year after the first shipment of API by the Company in the Territory (or upon such other times agreed to by the Finance Committee), the Finance Committee shall undertake a series of calculations to determine the amount, if any, of overpayment by ERS to the Company of Fully Burdened Manufacturing Cost for API during the preceding calendar year, as follows: (i) The Finance Committee shall review and determine the following information regarding the previous calendar year's production of API: -------------------------------------------------------------------------- Total Number of All Batches = total number of all (including successful, failed and non-conforming batches) API batches manufactured by the Company or attempted to be manufactured by the Company -------------------------------------------------------------------------- Total Number of Failed Batches = total number of all failed or non-conforming API batches manufactured by the Company or attempted to be manufactured by the Company -------------------------------------------------------------------------- 39 Confidential treatment requested by Bristol-Myers Squibb Company, Bristol-Myers Squibb Biologics Company and ImClone Systems Incorporated. -------------------------------------------------------------------------- Total Cost of Failed Batches = total cost of all failed or non-conforming API batches manufactured by the Company or attempted to be manufactured by the Company (as such are reported as part of Fully Burdened Manufacturing Cost for API during such calendar year) -------------------------------------------------------------------------- (ii) The Finance Committee shall undertake the following calculations: -------------------------------------------------------------------------- Average Cost Per Failed Batch = Total Cost of Failed Batches / Total Number of Failed Batches -------------------------------------------------------------------------- Allowable Number of Failures = Total Number of All Batches x Allowable Failure Rate applicable to the calendar year under review -------------------------------------------------------------------------- Number of Excess Failed Batches = Total Number of Failed Batches - Allowable Number of Failures -------------------------------------------------------------------------- (iii) If the Number of Excess Failed Batches is greater than zero, then the Finance Committee shall undertake the following calculation: -------------------------------------------------------------------------- Amount of Overpayment = Average Cost Per Failed Batch x Number of Excess Failed Batches -------------------------------------------------------------------------- If the Number of Excess Failed Batches is greater than zero, the Company shall reimburse ERS for the Amount of Overpayment within 3 business days after the completion of the calculation of such amount. Prior to receiving any such payment, ERS may elect to credit any such amount due against any payment owed to the Company under this Agreement. For purposes of such determinations, the "Allowable Failure Rate" for the manufacture of API, in the aggregate, in calendar years 2001 and 2002 shall be [**]; in calendar years 2003 and 2004, the "Allowable Failure Rate" for the manufacture of API shall be [**]; and in calendar year 2005 and in all subsequent calendar years, the "Allowable Failure Rate" for the manufacture of API shall be [**]. In the event the Finance Committee does not agree on the Amount of Overpayment, such matter shall be referred to the JEC for resolution. (d) Upon the Company's receipt of a claim that a shipment or batch thereof of API does not meet the Specifications and/or applicable Manufacturing Standards, the Company shall use commercially reasonable efforts to replace such shipment or batch thereof with an additional shipment of API that does conform to such standards as soon as practicable. 8.9 Third Party Manufacturers. The Parties acknowledge and agree that the Company currently obtains Finished Products through written contractual arrangements with Third Party Manufacturers. Upon the execution and delivery of this Agreement, the Company shall use 40 Confidential treatment requested by Bristol-Myers Squibb Company, Bristol-Myers Squibb Biologics Company and ImClone Systems Incorporated. commercially reasonable efforts to assign all such written contracts to ERS, and upon such assignment, the Company shall and hereby does represent and warrant that, as of the Effective Date, to the knowledge of the Company it is not in breach under any such contracts and that data and information provided to ERS by the Company relating to such contracts is accurate and complete in all material respects and contains no material errors or omissions. If any of such contracts are not assigned (after the Company's use of commercially reasonable efforts to secure their assignment under such contracts), ERS will reimburse the Company for the cost of producing Finished Product. The JMC shall prepare a strategy and transition plan for transitioning the production of Finished Products from such Third Party Manufacturers to ERS, which shall provide for a reasonably sufficient amount of time for ERS to be able to manufacture all of its requirements of Finished Products. The JMC may, from time to time, determine that the Company may use Third Party Manufacturers to supply all or some of the API it is required to supply to ERS under this Agreement. 8.10 Inventory Management ERS shall maintain inventory of Finished Product and API in accordance with ERS's usual and customary inventory management practices that ERS applies to its other therapeutic oncology products. 8.11 Shortage of Supply. (a) The Company shall notify ERS: (i) as promptly as possible, but in no event more than ten days after the Company's receipt of a firm order from ERS as provided in Section 8.4, or (ii) immediately upon becoming aware that the Company is unable to supply the quantity of API to ERS that the Company is required to supply hereunder, if the Company is unable to supply such quantities of API. In such event, the Company shall implement all commercially reasonable efforts to remedy such shortage, including through the use of Third Party Manufacturers for all or a portion of such quantities of API, as determined are necessary by the JMC. (b) In the event that the Company is unable to supply both ERS's requirements of API and the Company's and Third Parties' requirements for the API due to force majeure or otherwise, the Company shall allocate the API that the Company has in inventory and that the Company is able to produce among the quantities of all such requirements, so that ERS receives at least its proportionate share of such available supplies, as determined from reasonable forecasts (taking into consideration past sales and sales performance against forecast) and orders, for the API. 8.12 Inability to Supply. (a) In the event of any Short-Term Inability to Supply or Long-Term Inability to Supply, ERS shall be entitled in proportion to the supply shortfall to delay the incurrence of the Development Costs and/or the Distribution Costs, Sales Costs and/or Marketing Costs for the relevant period, until such Short-Term Inability to Supply or Long-Term Inability to Supply ends. The Clinical Budget and/or the relevant Marketing Budget shall be adjusted accordingly. Any issues relating to the application of this provision shall be subject to review by the relevant Committee, and any resolution of such matters shall require a consensus decision by such Committee, not subject to the tie-break mechanisms of the relevant Sections of this Agreement. (b) An "Inability to Supply" shall mean: (i) with respect to the supply of API for Registrational Studies or Non-Registrational Studies, the Company's failure for any reason, including without limitation force majeure reasons or otherwise, to supply ERS with quantities of API meeting the Specifications and Manufacturing Standards equal to at least [**] of the quantity of API set forth in the applicable time period on Exhibit 8.12(B)(i); and (ii) with respect to the supply of API for commercial sales, the Company's failure for any reason, including without limitation force majeure reasons or otherwise, to supply ERS with quantities of API meeting the Specifications and 41 Confidential treatment requested by Bristol-Myers Squibb Company, Bristol-Myers Squibb Biologics Company and ImClone Systems Incorporated. Manufacturing Standards equal to at least [**] of the quantity of API set forth in the applicable time period on Exhibit 8.12(B)(ii). (c) A "Short-Term Inability to Supply" is an Inability to Supply that is reasonably expected to continue for no more than a six-month period of time. (d) A "Long-Term Inability to Supply" shall mean any Inability to Supply that is reasonably expected to exceed or actually exceeds a six-month period of time. (e) In the event that ERS believes that any Long-Term Inability to Supply exists, ERS shall provide the Company with written notice of such claim and the JMC shall promptly meet to discuss such claims and to determine whether the alleged Long-Term Inability to Supply exists and whether it is due solely to a force majeure event. If the JMC does not reach a consensus decision in its deliberations regarding such claims, then the matter shall be referred to the JEC for resolution, provided that Sections 2.1(d)(ii), (iii) and (iv) shall not apply with respect to such matter. If the JEC does not reach consensus decision on the matter, then ERS may submit the matter to arbitration pursuant to the Accelerated Arbitration Provisions set forth in Section 16.13(b). The Parties shall reasonably and promptly cooperate with the JMC, JEC, and arbitrators, as the case may be, during their proceedings regarding such claims. (f) If a determination is made pursuant to Section 8.12(e), by the JMC, the JEC, or the arbitrators, as the case may be, that a Long-Term Inability to Supply exists, the JEC shall re-evaluate the Clinical Development Plans, Marketing Plans, Clinical Budget and/or the Marketing Budgets in view of such Long-Term Inability to Supply. If a determination is made pursuant to Section 8.12(e), by the JMC, the JEC, or the arbitrators, as the case may be, that a Long-Term Inability to Supply exists and is not due solely to a force majeure event, then: (i) for so long as such Long-Term Inability to Supply continues, the JMC shall be co-chaired by representatives of ERS and the Company and matters that are the subject of a deadlock arising in the JMC shall be resolved in accordance with the Accelerated Arbitration Provisions of Section 16.13(b); (ii) the Company shall reasonably cooperate with ERS to establish an alternative supply, including locating qualified third party manufacturers and sources of materials; and (iii) the JMC shall (with the understanding that the goal of the Parties shall be to transition the manufacture and supply of API back to the Company as soon as practicable, to the extent that such Long-Term Inability to Supply ceases to exist) authorize the taking of one or more the following actions to make up for the API supply shortfall, in the order of preference listed below, and with the understanding that performance of API supply obligations and responsibilities under each of the actions listed below shall be reasonably consistent with the scope of performance of such obligations and responsibilities contemplated to be performed by the Company as the primary source of API supply: first, make use of the internal capacity of BMS and/or ERS to fill the API supply shortfall; second, contract with a third party manufacturer to fill the API supply shortfall; and third, take such other actions as may be necessary for purposes of filling the API supply shortfall. (g) The Company shall reimburse ERS for all reasonable out-of-pocket costs incurred in connection with making up for a shortfall in API supply pursuant to Section 8.12(f); provided, 42 Confidential treatment requested by Bristol-Myers Squibb Company, Bristol-Myers Squibb Biologics Company and ImClone Systems Incorporated. however that such reimbursable costs shall not include the costs of purchasing API from a third party manufacturer or the costs of purchasing any component used to manufacture API for purposes of calculating Fully Burdened Manufacturing Cost as defined in Exhibit 1.35 (as applied to ERS) other than those directly relating to the startup of biologic operation for the Product, including any efficiency, activity and spending variances from standards as well as any underabsorbed overhead expenses incurred during such startup, including, without limitation, capital investments undertaken by ERS that are authorized by the JMC which relate to ERS's use, dedication, expansion, and/or creation of ERS's internal capability to supply API. The rights of ERS pursuant to this Section 8.12 shall not be affected in any way by ERS's waiver or failure to take action with respect to any previous failure by the Company. Any rights provided to ERS pursuant to this Section shall be in addition to any other rights or remedies available to ERS at law or in equity. (h) If a determination is made pursuant to Section 8.12(e), by the JMC, the JEC, or the arbitrators, as the case may be, that a Long-Term Inability to Supply exists and is due solely to a force majeure event, then the JMC shall meet to determine how to rectify such Long-Term Inability to Supply. If the JMC does not reach a consensus decision, then the matter shall be referred to the JEC for resolution, provided that Sections 2.1(d)(ii), (iii) and (iv) shall not apply with respect to such matter. If the JEC does not reach consensus decision on the matter, then any Party may submit the matter to arbitration pursuant to the Accelerated Arbitration Provisions set forth in Section 16.13(b). The Parties shall reasonably and promptly cooperate with the JMC, JEC, and arbitrators, as the case may be, during their proceedings regarding such Long-Term Inability to Supply. (i) In the event that ERS or a third party manufacturer is to supply API in accordance with Section 8.12(f), the Company shall fully cooperate with ERS or such third party manufacturer, as the case may be, and take all actions necessary to qualify them as a manufacturer of API, including, without limitation: (i) providing them with copies of all documentation within the Company's possession and control that is reasonably necessary for them to manufacture API; (ii) providing such technical assistance as is reasonably necessary to enable them to manufacture API in accordance with the Specifications and the applicable Manufacturing Standards; and (iii) to the extent that ERS or a third party manufacturer supplies API pursuant to Section 8.12(f), ERS shall be relieved of its obligation to purchase from the Company such quantities of API. 9.

At least 45 days before a manuscript is to be submitted to a publisher, the publishing Party will provide the PDC with a copy of the manuscript. If the publishing Party wishes to make an oral presentation, it will provide the PDC with a summary of such presentation at least 30 days before such oral presentation and, if an abstract is to be published, 30 days before such abstract is to be submitted. Any oral presentation, including any question period, shall not include any Confidential Information unless the Parties otherwise mutually agree in writing in advance of such oral presentation. 10.2 Review. The PDC will review the manuscript, abstract, text or any other material provided to it under Section 10.1 to determine whether patentable subject matter is disclosed. The PDC will notify the publishing Party within 30 days of receipt of the proposed publication if the PDC, in good faith, determines that patentable subject matter is or may be disclosed, or if the PDC, in good faith, believes Confidential Information is or may be disclosed. If it is determined by the PDC that patent applications should be filed, the publishing Party shall delay its publication or presentation for a period not to exceed 60 days from the PDC's receipt of the proposed publication or presentation to allow time for the filing of patent applications covering patentable subject matter. In the event that the delay needed to complete the filing of any necessary patent application will exceed the 60-day period, the PDC will discuss the need for obtaining an extension of the publication delay beyond the 60-day period. If it is determined in good faith by the PDC that Confidential Information or proprietary information is being disclosed, the Parties will consult in good faith to arrive at an agreement on mutually acceptable modifications to the proposed publication or presentation to avoid such disclosure. 10.3 Confidentiality; Exceptions. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing, the Parties agree that, during the term of this Agreement and for ten years thereafter, the receiving Party, its Affiliates and its licensees shall, and shall ensure that their respective employees, officers, directors and other representatives shall, keep completely confidential and not publish or otherwise disclose and not use for any purpose any information furnished to it or them by the disclosing Party, its Affiliates or its licensees or developed under or in connection with this Agreement, except to the extent that it can be established by the receiving Party by competent proof that such information: (i) was already known to the receiving Party, other than under an obligation of confidentiality, at the time of disclosure by the disclosing Party; (ii) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party; (iii) became generally available to the public or was 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; or (iv) 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 (all such information to which none of the foregoing exceptions applies, shall be deemed "Confidential Information"). 10.4 Exceptions to Obligation.
