Licensed Product for the Territory during the Term. Millennium will have the
right to grant sublicenses under this Section 7.2(b) to Third Parties solely for
the purposes of Developing or Manufacturing the Licensed Product for the
Territory. To the extent the GSK Other Intellectual Property includes "severable
improvements" within the meaning of Article 5 of the TTBE Regulation, the
license described above will not be co-exclusive. Instead GSK hereby grants
Millennium an irrevocable, paid-up, non-exclusive, non-royalty-bearing,
worldwide right and license, with the right to grant sublicenses, under GSK
Other Intellectual Property to Develop or Manufacture the Licensed Product for
the Territory during the Term.

this option any time during the Term by providing written notice to GSK,
declaring its intent to enter into a license agreement with GSK. [**], the
Parties will negotiate any such license in good faith and on commercially
reasonable terms within [**] following notification by Millennium of exercise of
said option, or for such additional time as may be mutually agreed by the
Parties. To the extent the GSK Other Intellectual Property includes "severable
improvements" within the meaning of Article 5 of the TTBE Regulation, the
license described above will not be exclusive. Instead GSK would grant
Millennium a non-exclusive, royalty-bearing right and license under GSK Other
Intellectual Property to Develop or Commercialize Licensed Product in, or
Manufacture Licensed Product for, outside the Territory.

Section 7.3. GSK INTELLECTUAL PROPERTY DEVELOPED BY GSK AFFILIATES AND
THIRD PARTY CONTRACTORS. To the extent that GSK contracts with its Affiliates or
Third Parties for the performance of GSK obligations hereunder, GSK shall obtain
the right under the intellectual property rights of such Affiliate or Third
Party related to the Licensed Product, with the right to grant sublicenses to
Millennium (and such license shall be further sublicensable by Millennium), to
use any intellectual property pertaining to the Licensed Product that is
discovered or developed by such Affiliate or Third Party under such contract for
the Development or Manufacture of Licensed Product throughout the world or the
Commercialization of the Licensed Product outside the Territory. In addition to
the foregoing, GSK shall use commercially reasonable efforts [**]with respect to
the Development, Manufacture or Commercialization of the Licensed Product in the
Territory, [**].

Section 7.4. MILLENNIUM RETAINED RIGHTS. Any rights of Millennium not
expressly granted to GSK under the provisions of this Agreement will be retained
by Millennium, including the right (a) to exploit Millennium Intellectual
Property to Develop Licensed Product in the Territory as permitted by this
Agreement and outside the Territory, (b) to Commercialize the Licensed Product
outside the Territory, and (c) to Manufacture the Licensed Product.

Section 7.5. GSK KNOW-HOW. Subject to the terms and conditions of this
Agreement, GSK hereby grants to Millennium a perpetual, irrevocable,

Commercialize the Licensed Product.

Section 7.6. MILLENNIUM'S PRODUCT TRADEMARKS. GSK, its Affiliates and
designees will, subject to this Section 7.6, use Millennium's Product Trademarks
on a royalty-free, fully paid up, (a) non-exclusive basis with respect to
Development, (b) exclusive basis with respect to Commercialization, and/or (c)
non-exclusive basis with respect to Secondary Packaging, in each case during the
Term in the Territory, and solely for display, advertising or informational
purposes in connection with such Development, Commercialization, and the conduct
of Secondary Packaging of the Licensed Product for the Territory, in accordance
with this Agreement. GSK will not at any time do or permit any act to be done
which may in any way impair the rights of Millennium in the Product Trademarks.

Section 7.7. COPYRIGHT.

use, display, modify, have modified, distribute, have distributed and make or
have made derivative works of Millennium's Copyrights on a royalty-free, fully

or advertising purposes in connection with Development and Commercialization of
the Licensed Product in the Territory, and the conduct of Secondary Packaging of
the Licensed Product for the Territory, in accordance with this Agreement. GSK
will not at any time do or permit any act to be done which may in any way impair
the rights of Millennium in Millennium's Copyrights.

Schering's Copyrights on a royalty-free, fully paid up, exclusive basis solely
to the extent necessary to permit GSK, its Affiliates or designees to use,
display, distribute, and have distributed all Licensed Product Promotional
Materials, educational materials, product labeling, product inserts and product
packaging used by Schering in Commercializing the Licensed Product in the
Territory, solely to the extent that such materials may display Schering's
Copyrights. GSK will not at any time do or permit any act to be done which may
in any way impair the rights of Schering in Schering's Copyrights.

Section 7.8. RIGHTS RETAINED BY BOTH PARTIES. Each Party will retain
the right to exploit Joint Intellectual Property after the Term, without any
duty to account to the other Party or obtain the other Party's consent for such
exploitation.

reduction.

(b) "Generic Erosion" means achievement by all Generic
Equivalents of a prescription market share equal to [**] percent ([**]%) or
greater in the aggregate of the total prescriptions for the particular Licensed
Product plus its Generic Equivalent(s), assessed on a moving basis for the last

(a) Within [**] Business Days after (a) the end of the calendar
quarter during which the First Commercial Sale occurred and (b) all subsequent
quarters, GSK will submit to Millennium a report, on a country-by-country and

records of the items underlying COGS, Net Sales, Supply Price Percentage, [**],
royalties and other amounts relating to the reports and payments required by
Article VIII. Either Party will have the right annually at its own expense to
have an independent, certified public accountant selected by the requesting
Party (the "Requesting Party") review any such records of the Party receiving
the audit request (the "Receiving Party") in the location(s) where such records
are maintained upon reasonable notice and during regular business hours and
under obligations of confidence, for the sole purpose of verifying the basis and
accuracy of payments made under this Agreement.

(a) If such examination results in a determination that Net
Sales have been understated or COGS have been overstated, then any resulting
underpayment or overpayment will be paid to the Requesting Party with interest
from the date originally due (calculated at a per annum rate equal to the prime
rate as published in the THE WALL STREET JOURNAL, Eastern Edition, on the first
day of each calendar quarter for as long as such payments are overdue), within
[**] after the date on which Requesting Party receives the accounting report. If
the audit results in a determination that Net Sales have been understated or
COGS overstated by more than [**]% for the period examined, the Receiving Party
will pay all fees, costs and expenses incurred by the Requesting Party in the
course of making such determination.

(b) In the event that any understatement of Net Sales [**] of
the Licensed Products pursuant to Section 1.54(a), with such adjustments not to
occur any later than [**] after the gross sales that are the subject of such
calculation took place, then the Parties agree that the [**]% threshold
described above [**] will apply to the amount of such underpayment.

Section 8.13. TAX MATTERS.

(a) GSK will make all payments to Millennium under this
Agreement without deduction or withholding except to the extent that any such
deduction or withholding is required by Law to be made on account of Taxes.

(b) Any Tax required to be withheld under Law on amounts payable
under this Agreement will promptly be paid by GSK on behalf of Millennium to the
appropriate Governmental Authority, and GSK will furnish Millennium with proof
of payment of such Tax. Any such Tax required to be withheld will be an deemed

intention to begin withholding any such Tax in advance and cooperate to reduce
such Tax on payments made to Millennium hereunder.

(c) GSK and Millennium will cooperate with respect to all
documentation required by any taxing authority or reasonably requested by GSK or
Millennium to secure a reduction in the rate of applicable withholding Taxes.

(d) Solely for purposes of this Section 8.13, "Tax" or "Taxes"
means any present or future taxes, levies, imposts, duties, charges, assessments
or fees of any nature (including interest, penalties and additions thereto) that
are imposed by Law.

Section 8.14. PAYMENT PROCEDURES. All dollar ($) amounts specified in
this Agreement are United States dollar amounts. All payments to be made by GSK
to Millennium will be made in U.S. Dollars, to a Millennium bank account able to
receive U.S. Dollars. All payments hereunder will be made by wire transfer to
such bank and account as Millennium may from time to time designate in writing.
Whenever any payment hereunder will be stated to be due on a day which is not a
Business Day, such payment will be made on the immediately succeeding Business
Day. Payments hereunder will be considered to be made as of the day on which
they are credited to Millennium's designated bank and account.

Section 8.15. CURRENCY EXCHANGE. If any Net Sales or COGS are stated in
a currency other than United States Dollars, then, for the purpose of
calculating the amount due to any Party hereunder, such Net Sales or COGS will
be converted into United States Dollars at the exchange rate between those two
currencies most recently quoted in the Wall Street Journal in New York as of the
last Business Day of the calendar quarter for which such amounts are being paid.
If no such exchange rate has been quoted in the Wall Street Journal in New York
at any time during the twelve (12) month period preceding the date on which such
amount becomes due to a Party, such Net Sales or COGS will be deemed to be equal
to the average Net Sales or COGS for such Licensed Product in the Territory for
the most recently completed calendar quarter, as stated in Euros.

Section 8.16. LATE PAYMENTS. Any amounts that are not paid on or before
the date such payments are due under this Agreement will bear interest at an
annual rate of interest equal to the prime rate of interest, plus two (2)
percentage points, as published in the WALL STREET JOURNAL, Eastern Edition, on
the first day of each calendar quarter for as long as such payments are overdue
calculated on the number of days such payment is delinquent.

related packaging materials and Promotional Materials, in both written and
electronic forms. If Millennium reasonably objects to the usage of the Product
Trademark(s) or GSK Product Trademark(s) in connection with any sample, it will
give written notice of such objection to GSK within [**] days of receipt by
Millennium of such sample, specifying the way in which such usage of its Product
Trademark(s) or GSK Product Trademark(s) fails to meet the style, usage or
quality standards for the Licensed Product or Promotional Materials set forth in
the first sentence of this Section 9.7(c), and GSK will cease sale and
distribution of any units of the Licensed Product or Promotional Materials that
fail to meet the style, usage or quality standards in the same manner as the
sample objected to by Millennium as soon as commercially practicable so long as
supply of the Licensed Product is not disrupted. GSK will remedy the failure and
submit further samples to Millennium for approval. Millennium will cooperate
with GSK to insure that issues related to Product Trademark(s) and GSK Product
Trademark(s) do not compromise the supply or distribution chain of the Licensed
Product. In addition, GSK will: (i) use the GSK Product Trademark(s) and the
Product Trademark(s) in compliance with all relevant Laws and regulations; and
(ii) not modify any of the GSK Product Trademark(s) and the Product Trademark(s)
in any way and not use any GSK Product Trademark or Product Trademark on or in
connection with any goods or services other than the Licensed Product in the
Territory.

(d) In no event will GSK: (i) establish, operate, sponsor or
contribute content to any site on the Internet which incorporates the word
"INTEGRILIN," any of Millennium's trademarks, service marks or trade names (the
"Millennium Trademarks") or any variation or part of such word or Millennium
Trademark as its URL address or any part of such address; (ii) register any
domain name which incorporates the word "INTEGRILIN" or Millennium Trademarks;
(iii) register any Millennium Trademarks or any trademarks, service marks or
trade names that are confusingly similar to any of the word "INTEGRILIN" or
Millennium Trademarks; (iv) form (or change the name of) any corporation or
other entity under or to a name which incorporates any of the word "INTEGRILIN"
or Millennium Trademarks; or (v) at any time during or after the Term, in order
to attract visitors to any site on the Internet, (A) use "INTEGRILIN," any
Millennium Trademark or any variation or part thereof as a meta-tag or invisible
text or on any unused frame or bridge page, (B) purchase "INTEGRILIN," any
Millennium Trademark or any variation or part thereof as a search term from any
search engine; or (C) engage in any other practice designed to direct web
browsers using search engines to different web pages or versions of web pages
than the pages corresponding to search terms entered by the user (including
"bridge pages," "cloaking" or "pagejacking").

(e) Should GSK have an interest in the inclusion of a specific
reference to the Product Trademarks on the content of a site on the internet
Controlled by GSK, it will notify Millennium. GSK will provide detailed
information on the proposed location and use of the Product Trademark. The
Parties agree to discuss the details of such proposed use and review its
compliance with all applicable Laws. If the Parties mutually agree on such
specific use of the Product Trademark, then GSK will implement such use, subject
to this Section 9.7. If the Parties do not mutually agree on the proposed use of
the Product Trademark by GSK, then GSK will not implement the proposed reference
to the Product Trademark. Any modification or alteration to the agreed upon
reference to the Product Trademark will be considered a new specific reference
to the Product Trademark and the proposed modification or alteration thus not
allowed without review and mutual approval by the Parties in accordance with the
terms of this Section 9.7(e).

(f) Millennium will use commercially reasonable efforts to
establish, maintain and enforce the Product Trademark(s) and the GSK Product
Trademark(s) during the Term in all countries in the Territory where such
Product Trademark(s) and GSK Product Trademark(s) are registered as of the
Effective Date, a listing of which is attached hereto as EXHIBIT D. If
Millennium elects not to undertake to establish, maintain and enforce the
Product Trademark(s) and the GSK Product Trademark(s) during the Term in any
country in the Territory (or, after commencement of such establishment,
maintenance and/or enforcement, desires to cease such prosecution, maintenance
or enforcement in such country of the Territory), then Millennium will notify
GSK of such election and GSK will be entitled to establish, maintain and enforce
the Product Trademark(s) and the GSK Product Trademark(s) in such country of the
Territory. Irrespective of which Party has the right to establish, maintain, or
enforce the Product Trademark(s) and the GSK Product Trademark(s) during the
Term in the Territory, GSK will be responsible for [**]% of the costs of
establishment, maintenance and enforcement efforts for the Licensed Product in
the Territory and GSK will reimburse Millennium for all such costs incurred by
Millennium within [**] days after receiving an invoice from Millennium for such
costs, accompanied by reasonable substantiation thereof.

(g) If either Party becomes aware of any infringement of any
Product Trademark or GSK Product Trademark by a Third Party, such Party will
promptly notify the other Party and the Parties will consult with each other and
jointly determine the best way to prevent such infringement, including by the
institution of legal proceedings against such Third Party.

CONFIDENTIALITY AND PUBLICITY

Section 10.1. CONFIDENTIAL INFORMATION. During the Term and for a
period of [**] years after any termination or expiration hereof, each Party
agrees to keep in confidence and not to disclose to any Third Party, or use for
any purpose, except pursuant to, and in order to carry out, the terms and
objectives of this Agreement, any Confidential Information of the other Party.
The Parties will use commercially reasonable efforts, consistent with reasonable
business practices, to (x) label or identify as "CONFIDENTIAL", at the time of
disclosure, or by written notice to the other Party, within thirty (30) days
following such disclosures, Confidential Information which is disclosed in
writing or other tangible form, and (y) reduce to writing or other tangible form
and similarly label, within thirty (30) days of disclosure, Confidential
Information which is disclosed verbally. The terms of this Agreement will be
considered Confidential Information hereunder. The restrictions on the
disclosure and use of Confidential Information set forth in the first sentence
of this Section 10.1 will not apply to any Confidential Information that:

(a) was known by the receiving Party prior to disclosure by the
disclosing Party hereunder (as evidenced by the receiving Party's written
records or other competent evidence);

(b) is or becomes part of the public domain under circumstances
involving no breach of this Agreement;

(c) is disclosed to the receiving Party by a Third Party who had
a legal right to make such disclosure without restrictions for the benefit of
the disclosing Party; or

(d) is independently developed by personnel of the receiving
Party who did not have access to the Confidential Information (as evidenced by
the receiving Party's written records or other competent evidence).

The foregoing notwithstanding, if either Party is required (as reasonably
determined by its legal counsel) by regulation, Law or legal process, including
without limitation by the rules or regulations of the United States Securities
and Exchange Commission or similar regulatory agency in a country other than the
United States or of any stock exchange or Nasdaq, to disclose the existence of
this Agreement and/or any information related to the terms and conditions of
this Agreement, such Party will provide prior written notice of such intended
disclosure to the other Party, which notice will include a copy of the proposed
disclosure. Upon receipt of such notice, the other Party will have a reasonable
period to review and comment on the proposed disclosure (not to exceed five (5)
Business Days), and the Party required to disclose will in good faith consider
any changes or modifications to the proposed disclosure requested by the other
Party. In the event that the legal requirements compelling such disclosure will
not reasonably allow for a review period of five (5) Business Days, the notice
provided by the Party required to disclose will specify a shorter period for
review (of not less than one (1) Business Day) necessary under such
circumstances. The Party legally required to disclose will use commercially
reasonable efforts to obtain confidential treatment (to the extent available) of
the Confidential Information proposed to be disclosed, and will disclose only
such Confidential Information of the other Party as is required to be disclosed
in order to comply. In addition, either Party may disclose to bona fide
potential investors, lenders and acquirors/acquirees, and to such Party's
consultants and advisors, the existence and terms of this Agreement only if and
to the extent necessary in connection with a proposed equity or debt financing
of such Party, or a proposed acquisition, merger or other similar business
combination, so long as such recipients are bound in writing to maintain the
confidentiality of such information in accordance with the terms of this
Agreement.

Section 10.2. EMPLOYEE, CONSULTANT AND ADVISOR OBLIGATIONS. Each Party
agrees that it and its Affiliates will provide or permit access to Confidential
Information received from the other Party and such Party's Affiliates and
representatives only to the employees, consultants, advisors and permitted
subcontractors, sublicensees, distributors and sub-distributors of the receiving
Party and its Affiliates, who in such Party's reasonable judgment have a need to
know such Confidential Information to assist the receiving Party with the
activities contemplated by this Agreement and who are subject to contractual
obligations of confidentiality and non-use with respect to such Confidential
Information similar to the obligations of confidentiality and non-use of the
receiving Party pursuant to Section 10.1; provided, that Millennium and GSK will
each remain responsible for any failure by its Affiliates, and its and its
Affiliates' employees, consultants, advisors and permitted subcontractors,
sublicensees, distributors and sub-distributors, to treat such Confidential
Information as required under Section 10.1 (as if such Affiliates, employees,
consultants, advisors and permitted subcontractors, sublicensees, distributors
and sub-distributors were Parties directly bound by the requirements of Section
10.1).

Section 10.3. PUBLICITY. Upon the execution of this Agreement,
Millennium and GSK will issue a mutually agreed press release regarding the
subject matter of this Agreement. After such initial press release, neither
Party will issue a press release or public announcement relating to the Licensed
Product in the Territory or this Agreement without the prior written approval of
the other Party, which approval will not be unreasonably withheld, except that a
Party may (a) issue such press release or public announcement if the contents of
such press release or public announcement have previously been made public other
than through a breach of this Agreement by the issuing Party and (b) issue such
a press release or public announcement if required by applicable Law, in each
case under clause (a) and (b) after first notifying the other Party of such
planned press release or public announcement at least three (3) Business Days in
advance of issuing such press release or making such public announcement (or,
with respect to press releases and public announcements made pursuant to the
foregoing clause (b), with as much advance notice as possible under the
circumstances if it is not possible to provide notice at least three (3)
Business Days in advance) for the sole purpose of allowing the other Party to
review the proposed press release or public announcement for the inclusion of
Confidential Information, provided, that, the Party subject to the requirement
will include in such press release or public announcement made pursuant to the
foregoing clause (b) only such information relating to the Licensed Product or
this Agreement as is required by such applicable Law.

Section 10.4. PUBLICATIONS. Subject to the restrictions provided below,
GSK may publish or present the results of Development carried out on the
Licensed Product in the Territory, subject to prior review by Millennium for
patentability and protection of Millennium's Confidential Information. GSK will
provide Millennium any proposed abstracts, manuscripts or summaries of
presentations that cover the results of Development of the Licensed Product at
least thirty (30) days' prior to its proposed submission for publication or
presentation. Millennium will designate a person or persons who will be
responsible for reviewing such publications. Such designated person will respond
in writing promptly and in no event later than thirty (30) days after receipt of
the proposed material with either approval of the proposed material or a
specific statement of concern, based upon either the need to seek patent
protection or concern regarding competitive disadvantage arising from the
proposal. If Millennium expresses such a concern, GSK agrees not to submit such
publication or to make the presentation that contains such information until
Millennium is given a reasonable period of time (not to exceed ninety (90) days)
to seek patent protection for any material in such publication or presentation
that it believes is patentable or to resolve any other issues, and GSK will
remove any Confidential Information of Millennium from the publication if
requested by Millennium. With respect to proposed abstracts, manuscripts or
summaries of presentations by investigators (including results of Investigator
Sponsored Clinical Studies) or other Third Parties (other than Schering), such
materials will be subject to review under this Section 10.4 to the extent that
GSK has the right and ability (after using Commercially Reasonable Efforts) to
do so.

(e) CLAIMS FOR INDEMNIFICATION.

(i) A person entitled to indemnification under this Section
11.8 (an "Indemnified Party") will give prompt written notification to the
person from whom indemnification is sought (the "Indemnifying Party") of the
commencement of any action, suit or proceeding relating to a Third Party or
Governmental Authority claim for which indemnification may be sought or, if
earlier, upon the assertion of any such claim by a Third Party or Governmental
Authority (it being understood and agreed, however, that the failure by an
Indemnified Party to give notice of a Third Party or Governmental Authority
claim as provided in this Section 11.8 will not relieve the Indemnifying Party
of its indemnification obligation under this Agreement except and only to the
extent that such Indemnifying Party is actually prejudiced as a result of such
failure to give notice).

(ii) Within [**] days after delivery of such notification,
the Indemnifying Party may, upon written notice thereof to the Indemnified
Party, assume control of the defense of such action, suit, proceeding or claim
with counsel reasonably satisfactory to the Indemnified Party. If the
Indemnifying Party does not assume control of such defense, the Indemnified
Party will control such defense.

(iii) The Party not controlling such defense may participate
therein at its own expense; provided, that if the Indemnifying Party assumes
control of such defense and the Indemnified Party reasonably concludes, based on
advice from counsel, that the Indemnifying Party and the Indemnified Party have
conflicting interests with respect to such action, suit, proceeding or claim,
the Indemnifying Party will be responsible for the reasonable fees and expenses
of counsel to the Indemnified Party solely in connection therewith; provided
further, however, that in no event will the Indemnifying Party be responsible
for the fees and expenses of more than one counsel in any one jurisdiction for
all Indemnified Parties.

(iv) The Party controlling such defense will keep the other
Party advised of the status of such action, suit, proceeding or claim and the
defense thereof and will consider recommendations made by the other Party with
respect thereto.

(v) The Indemnified Party will cooperate fully with the
Indemnifying Party and its legal counsel (including the provision of testimony
or documents) with respect to the defense or settlement of any such action,
suit, proceeding or claim.

(vi) The Indemnified Party will not agree to any settlement
of such action, suit, proceeding or claim without the prior written consent of
the Indemnifying Party, which will not be unreasonably withheld. The
Indemnifying Party will not agree to any settlement of such action, suit,
proceeding or claim or consent to any judgment in respect thereof that does not
include a complete and unconditional release of the Indemnified Party from all
liability with respect thereto or that imposes any liability or obligation on
the Indemnified Party without the prior written consent of the Indemnified
Party, which consent will not be unreasonably withheld.

Section 11.9. INSURANCE. Each Party will maintain insurance, including
product liability insurance, with respect to its activities or obligations
hereunder. Such insurance will be in such amounts and subject to such
deductibles as the Parties may agree based upon standards prevailing in the
industry at the time, provided, that, as of the Effective Date, each Party will
maintain a minimum of Twenty Million Dollars ($20,000,000) in product liability
insurance. Notwithstanding the preceding two sentences, either Party may satisfy
its obligations hereunder through reasonable self-insurance to the same extent.
A Party will name the other Party as an additional insured on any policies it
maintains pertaining to the Development, Manufacturing or Commercialization of
the Licensed Product.

ARTICLE XII

TERM AND TERMINATION

Section 12.1. TERM. Unless terminated earlier in accordance with this
Article XII, this Agreement will commence on the Effective Date and will remain
in force and effect until the later of (a) December 31, 2014, or (b) for as long
as GSK continues to Commercialize the Licensed Product in any country in the
Territory (the "Term"). Upon expiration or earlier termination of this
Agreement, the licenses granted to GSK under Article VII will terminate.

Section 12.2. TERMINATION FOR MATERIAL BREACH. Upon any material breach
of this Agreement by a Party (the "Breaching Party"), the other Party (the
"Non-Breaching Party") may terminate this Agreement by providing thirty (30)
days' written notice to the Breaching Party if such material breach is a breach
of a payment obligation, or sixty (60) days' written notice to the Breaching
Party in the case of any other material breach. The termination will become
effective at the end of the notice period unless the Breaching Party cures such
breach during such notice period; provided, that the Non-Breaching Party may, by
notice to the Breaching Party, designate a later date for such termination in
order to facilitate an orderly transition of activities relating to the Licensed
Product. Notwithstanding the foregoing,

(a) if such breach, by its nature, is incurable, the
Non-Breaching Party may terminate this Agreement immediately upon written notice
to the Breaching Party;

(b) if such breach (other than a payment breach), by its nature,
is curable, but not within the applicable cure period, then such cure period
will be extended if the Breaching Party provides an appropriate written plan for
curing such breach to the Non-Breaching Party and uses commercially reasonable
efforts to cure such breach in accordance with such written plan; provided that
no such extension will exceed sixty (60) days without the consent of the
Non-Breaching Party; and

(c) if there is a good faith dispute as to whether performance
has been made by either Party pursuant to this Agreement, the relevant cure
period with respect thereto will be tolled pending resolution of such dispute in
accordance with the applicable provisions of this Agreement.

Section 12.3. TERMINATION BY GSK. GSK has the right to terminate this
Agreement as set forth in this Section 12.3.

(a) TERMINATION ARISING FROM GSK ELECTIVE DECISION TO
DISCONTINUE COMMERCIALIZATION OF LICENSED PRODUCT PRIOR TO GENERIC Erosion. If
based on a reasonable determination, the Commercially Reasonable Efforts to be
undertaken by GSK for Development and Commercialization do not justify, in GSK's
sole discretion, the continued Commercialization of the Licensed Product, then
GSK may, upon written notice to Millennium, terminate this Agreement in the
Territory as a whole; provided, however, that GSK [**]. In the event that
GSK chooses to exercise its right of termination under this provision, [**];
provided, however, that in the event that GSK's decision not to continue the
Commercialization of the Licensed Product is due to: (i) actions by a Government
or Regulatory Agency that results in the [**] of the Licensed Product in the
Major Market Countries by greater than [**] percent ([**]%), or (ii) actions by
a Government or Regulatory Agency to [**] for the Licensed Product in the Major
Market Countries, or (iii) [**] in connection with Commercialization [**] of the
Licensed Product in the Territory [**] per cent ([**]%) [**], in each case, not
directly or indirectly caused by the actions or inactions of GSK, then in such
event GSK may terminate this Agreement [**].

(b) TERMINATION BY GSK DUE TO GENERIC COMPETITION. In the event
GSK elects to stop Commercializing the Licensed Product in the Major Market
Countries after Generic Erosion has occurred pursuant to Section 8.5, which
countries accounted for [**]percent ([**]%) or more of the total sales in the
Territory [**], GSK will promptly send written notice to Millennium of such
election and either Party will have the opportunity to terminate this Agreement.

(c) TERMINATION BY GSK DUE TO COMPETING PRODUCT. If GSK elects
to retain a Competing Product pursuant to Section 11.4 hereof, GSK will notify
Millennium and [**] and this Agreement will terminate.

(d) TERMINATION BY GSK FOR SAFETY ISSUES. GSK may unilaterally
terminate this Agreement for the Territory as a whole if (i) the withdrawal of
the Licensed Product from the market in the United States, or one or more of
France, Germany, Italy, Spain or the United Kingdom for all indications and uses
(other than compassionate uses requested or required by any Regulatory
Authority) for health or safety reasons is ordered or required by the FDA, EMEA
or other Regulatory Authority, or (ii) the Parties reasonably agree that there
is a significant patient health or safety issue with respect to the Licensed
Product which may lead to any of the events enumerated in the immediately
preceding clause 12.3(d)(i).

(e) TERMINATION UPON TERMINATION OF THE SUPPLY AGREEMENT. GSK
may elect to terminate this Agreement for the Territory as a whole upon any
termination of the Supply Agreement or the Future Supply Agreement.

(f) TERMINATION BY GSK FOR DELAYED TRANSITION. In the event the
Transition Activities and Processes listed on Exhibit H have not been completed
by [**] and such lack of completion is not due to the gross negligence or
willful misconduct of GSK, GSK may terminate this Agreement for the Territory as
a whole [**] prior written notice to Millennium. During such notice period, upon
Millennium's request, the Executive Officers for each Party will discuss the
situation; provided, however, if the Transition Activities and Processes listed
on Exhibit H have not been completed by [**], GSK may proceed with termination
in its sole discretion. If GSK terminates this Agreement pursuant to this
Section 12.3(f) Millennium will [**] days of the date of termination.

actions as may be reasonably requested by Millennium in order to give effect to
the foregoing clauses (a) through (j); and

(l) Until the earlier of (i) [**] or (ii) [**] this Agreement,

ARTICLE XIII

FINAL DECISION-MAKING; DISPUTE RESOLUTION

Section 13.1. REFERRAL TO EXECUTIVE OFFICERS. In general the Parties
will use good faith efforts to resolve matters at the Steering Committee by
consensus. If for any reason the Steering Committee cannot resolve any matter
properly referred to it pertaining to the Licensed Product in the Territory
either Party may refer the matter to the Executive Officers for resolution. If
after discussing the matter in good faith and attempting to find a mutually
satisfactory resolution to the issue, the Executive Officers fail to come to
consensus within [**] Business Days after the date on which the matter is
referred to the Executive Officers (unless a longer period is agreed to in
writing by the Executive Officers), the provisions of Sections 13.2 and 13.3
will apply and resolutions reached through such provisions will be binding on
the Parties.

Section 13.2. FINAL DECISION-MAKING AUTHORITY. If the Executive
Officers fail to come to consensus on any matter referred to them within the
period for resolution set forth in Section 13.1 (an "Unresolved Matter"), then
the following provisions will apply:

(a) GSK will have final decision-making authority with respect
to Unresolved Matters with respect to the pricing or reimbursement of the
Licensed Product in the Territory, [**] in the Territory in connection with the
Development and Commercialization of the Licensed Product, the contents of the
label for the Licensed Product in the Territory other than those contents
related to patient safety, Promotional Materials and the Commercialization
strategy, including those set forth in the Launch Plan and Annual Plan, for the
Licensed Product in the Territory.

(b) Millennium will have final decision-making authority with
respect to Development activities where Millennium reasonably believes that
conduct of the proposed Development activity [**] of the Licensed Product
outside the Territory.

(c) All other Unresolved Matters arising in connection with
disputes under this Agreement, including but not limited to patient health or
safety matters, financial provisions, diligence and any disputes regarding the
Supplemental Plan will be handled pursuant to Section 13.3 hereof.

(d) For purposes of clarity, Millennium will have final
decision-making authority with respect to all matters arising in connection with
the Development, Manufacture and Commercialization of the Licensed Product
outside the Territory.

Section 13.3. ARBITRATION. Any dispute, controversy or claim arising
out of or relating to this Agreement, or the breach, termination or invalidity
thereof, in each case which is not subject to Section 13.1 or 13.2, shall be
finally settled by binding arbitration conducted in the English language in
Cambridge, Massachusetts under the commercial arbitration rules of the American
Arbitration Association ("AAA"). The arbitration shall be conducted by a single
arbitrator jointly appointed by the Parties; provided, HOWEVER, that if they
cannot agree within thirty (30) days after the initiation of the arbitration,
then the arbitrator shall be appointed by the President of the AAA. Disputes
about arbitration procedure shall be resolved by the arbitrator. The arbitrator
may proceed to an award notwithstanding the failure of either Party to
participate in the proceedings. Discovery shall be limited to mutual exchange of
documents relevant to the dispute, controversy or claim; depositions shall not
be permitted unless agreed to by both Parties. The arbitrator shall be
authorized to grant interim relief, including to prevent the destruction of
goods or documents involved in the dispute, protect trade secrets and provide
for security for a prospective monetary award. The limitations on liability set
out in Section 14.10 hereof shall apply to an award of the arbitrator.
Specifically, but without limitation, under no circumstances shall the
arbitrator be authorized to award punitive or multiple damages. Any purported
award of punitive or multiple damages or of other damages not permitted under
Section 14.10 hereof shall be beyond the arbitrator's authority, void, and
unenforceable. The prevailing Party shall be entitled to an award of reasonable
attorney fees incurred in connection with the arbitration in such amount as may
be determined by the arbitrator. The award of the arbitrator shall be the sole
and exclusive remedy of the Parties and shall be enforceable in any court of
competent jurisdiction, subject only to revocation on grounds of fraud or clear
bias on the part of the arbitrator. Notwithstanding this, application may be
made to any court for a judicial acceptance of the award or order of
enforcement. Notwithstanding anything contained in this Section 13.3 to the
contrary, each Party shall have the right to institute judicial proceedings
against the other Party or anyone acting by, through or under such other Party,
in order to enforce the instituting Party's rights hereunder through reformation
of contract, specific performance, injunction or similar equitable relief.

Section 13.4. INTENDED THIRD PARTY BENEFICIARY.

(a) The Parties intend that, effective on the Effective Date,
GSK shall be deemed an intended third party beneficiary of the
Schering/Millennium European Agreement, including, without limitation, with the

covenants of Schering stated in Article X of such agreement with respect to:

(i) Millennium's rights to Develop, Commercialize and
Manufacture Licensed Products in the Territory under this Agreement;

(ii) Schering's obligations under Sections 3.2(c), 3.2(d),
3.3, 3.4, 4.3, 4.4, 5.1, 5.2, 5.3, 7.2 and 8.1 of the Schering/Millennium
European Agreement; and

(iii) Schering's indemnification obligations under Sections

Agreement.

Schering/Millennium European Agreement. In addition, GSK agrees to be bound by
Section 12.3 of the Schering/Millennium European Agreement with regard to its
enforcement of the terms of such agreement as an intended third party
beneficiary, and to join or be joined by Schering or Millennium in any
proceeding described in Section 12.3 of such agreement relevant to GSK. GSK
agrees to be bound by the dispute resolution provisions of such agreement with
regard to its enforcement of the terms of such agreements as an intended third
party beneficiary, and to agree to join or be joined by Schering or Millennium
in any proceeding described in the dispute resolution provisions of such
agreements; PROVIDED HOWEVER, that GSK may enforce its rights as a third party
beneficiary hereunder by going directly to dispute resolution under Section
12.3(b) of the Schering/Millennium European Agreement; provided, further that
GSK will be permitted, in such instance in which GSK initiates such proceeding,
to select, in lieu of Millennium, at least of one (1) of the three (3)
arbitrators to decide such dispute if the AAA rules governing the dispute so
provide and the parties each select one (1) arbitrator who then will select the
third arbitrator. Millennium agrees that Millennium and Schering will not modify
or amend the terms of the Schering/Millennium European Agreement with respect to
the provisions set forth above in this Section 13.4(a) without the prior written
consent of GSK, which consent shall not be unreasonably withheld. Millennium
agrees that GSK may exercise its rights under this Agreement and its rights
under the Schering/Millennium European Agreement independently.

(b) The Parties intend that, effective on the Effective Date,
the Schering Indemnified Parties, individually or collectively, shall be deemed
intended third party beneficiaries of this Agreement with respect to GSK's
indemnification obligations under Section 11.8(d)(iii) of this Agreement.

rights under the Schering/Millennium European Agreement independently.
