-14-

no event more than thirty (30) days following the Effective Date), each Party shall designate by written notice its initial representatives on the JSC. Thereafter, if AVEO provides written notice to Schering-Plough that it elects not to participate in the JSC, the JSC shall be disbanded and all decisions and responsibilities previously in the purview of the JSC shall be made and assumed by Schering-Plough. The JSC shall appoint a chairperson from among its members, who shall alternate annually between representatives of AVEO and representatives of Schering-Plough, with the first such chairperson being an AVEO representative. Each Party shall be free to change its representatives on written notice to the other or to send a substitute representative to any JSC meeting; provided, however, that each Party will ensure that at all times during the existence of the JSC, its representatives on the JSC are appropriate in terms of expertise and seniority (including at least one member of senior management) for the then current stage of Research and Development of Licensed Products. At the end of the Development Term, the JSC shall be disbanded and Schering-Plough shall assume all responsibilities of the JSC. Thereafter, the Parties shall meet semi-annually at mutually agreed times and places to discuss Development activities under this Agreement.

2.2. Meetings. The JSC shall meet on a quarterly basis, or more often as the Parties shall agree. Meetings of the JSC shall alternate between the offices of AVEO and Schering-Plough. A JSC member of the Party hosting the meeting shall serve as secretary of that meeting, who shall be responsible for preparing the minutes of the meeting.

-27-

(n) If any milestone set forth in Section 7.5(a) (the “Preclinical Milestone”), Sections 7.5(b), (c), or (d) (the “Clinical Milestones”) or in Sections 7.5(e) or (f) (the “Regulatory Milestones”) is achieved with respect to a Licensed Product prior to the achievement of an earlier Preclinical Milestone, Clinical Milestone or Regulatory Milestone (as the case may be) for such Licensed Product, then all milestone payments due and payable for the earlier Preclinical Milestone or Clinical Milestone (as the case may be) shall be due and payable simultaneously with the payment for achievement of the later milestone event. In the event a Pivotal Trial is deemed to be a [**], then the milestone set forth in Section 7.5(d) shall only be due when the trial progresses to the [**]. In the event of acceptance of [**], and the receipt of [**], milestones paid for acceptance of the [**] shall only be made once for such Indication. For purposes of clarity, if, with respect to any Licensed Product for an Indication, Schering-Plough initiates a [**] and upon completion of such [**] Schering-Plough files for [**], and subsequently receives such accelerated [**], then (i) Schering-Plough shall be obligated to pay the milestone under Section 7.5(e) or (f) (as applicable) upon the filing for [**], if such milestone (e) or (f) has not previously been paid for an Indication, (ii) Schering-Plough shall pay the milestone under Section 7.5(g) or 7.5(j) upon receipt of such [**], (iii) Schering-Plough shall pay the milestone set forth in Section 7.5(d) at such time as a [**] is initiated, it being understood that the initiation of such [**] is likely to occur (and Schering-Plough shall initiate such [**]) after the receipt of [**], and (iv) Schering-Plough shall not be obligated to pay for a second time the milestone set forth in Section 7.5(g) or 7.5(j) upon receipt of [**].

(o) If Development of any Licensed Product ceases (a “Failed Licensed Product”), and Development of another Licensed Product (a “Back-Up Product”) subsequently commences or continues, then any of the Preclinical Milestone, Clinical Milestone or Regulatory Milestone payments previously made by Schering-Plough in connection with such Failed Licensed Product shall be fully credited against any subsequent or repeated achievement of such milestone by the Back-Up Product.

(p) In addition, for each Licensed Product, on a one-time basis in each of the United States, the EU and Japan, Schering-Plough will pay AVEO an additional [**] percent ([**]%) of the applicable Commercial Milestone amounts set forth in Sections 7.5 (g) or (j), (h) or (k), and (i) or (l) upon Regulatory Approval of the first Indication in such country or territory where such Regulatory Approval for such Indication includes in the labeling a claim for the identification of a targeted patient population and where such label claim is also the subject of a Valid Claim of an AVEO Patent Right in such country or territory. For the avoidance of doubt, for each Licensed Product, such amounts shall only be paid once for Sections 7.5(g) or (j), once for Sections 7.5(h) or (k) and once for Sections 7.5(i) or (l).

Greater than $[**] and less than or equal to $[**]		[**]	%
Greater than $[**] and less than or equal to $[**]		[**]	%

Royalties under this Section 7.6 on aggregate Net Sales of any Licensed Product in the Territory in a Calendar Year shall be paid at the rate applicable to the portion of Net Sales within each of the Net Sales levels during such Calendar Year. For example, if, during a Calendar Year, Net Sales of a particular Licensed Product were equal to $[**], then the royalties payable by Schering-Plough would be calculated by adding (i) the royalties with respect to the first $[**].

Schering-Plough’s royalty obligations to AVEO under this Section 7.6 shall commence on a country-by-country and Licensed Product-by-Licensed Product basis on the First Commercial Sale of such Licensed Product and shall expire on a country-by-country basis and Licensed Product-by-Licensed Product basis on the later of: (i) the expiration of the last Valid Claim (that is not a patent claim to a Biomarker) of the AVEO Patent Rights or Joint Patent Rights Covering such Licensed Product in such country, or (ii) the tenth (10th) anniversary of the date of the First Commercial Sale by Schering-Plough or any of its Affiliates or Sublicensees to a non-Sublicensee Third Party of such Licensed Product in such country (the “Royalty Term”). The foregoing provisions of this Section 7.6(c) notwithstanding, the royalties payable with respect to Net Sales of a Licensed Product shall be reduced to [**] percent ([**]%) of the amounts otherwise payable pursuant to Section 7.6(a) during any portion of the Royalty Term when there is no Valid Claim (that is not a patent claim to a Biomarker) of the AVEO Patent Rights or Joint Patent Rights Covering such Licensed Product in such country; provided that such reduction shall not apply if the Licensed Product is entitled to Marketing Exclusivity in such country and there are no other products on the market in such country that contain substantially the same active ingredient as that contained in the Licensed Product.

-29-

(d) Third Party Royalties. If Schering-Plough reasonably determines that, in order to Commercialize a Licensed Product and avoid infringement of any patent not licensed hereunder, it is necessary or advisable to obtain a license from a Third Party and to pay a royalty or other payments under such patent (“Third Party Patent Licenses”), [**] percent ([**]%) of any royalties or other payments paid under Third Party Patent Licenses by Schering-Plough, its Affiliates or Sublicensees, shall be creditable against royalties payable to AVEO hereunder. In addition, Schering-Plough shall be responsible for all payments required under the AVEO Third Party Agreements; provided that [**] percent ([**]%) of any royalties paid by Schering-Plough pursuant to any of the AVEO Third Party Agreements shall be creditable against royalties on the Net Sales of Licensed Products payable to AVEO hereunder. In no event shall all such credits available under this Section 7.6(d), in the aggregate, cause the royalties paid to AVEO for any particular Calendar Quarter to be reduced by more than [**] percent ([**]%) of the royalties otherwise payable on Net Sales of such Licensed Product in such country; provided that any reduction hereunder, or portion thereof, that is rendered not usable pursuant to the immediately preceding proviso may be carried forward for use in future Calendar Quarters.

7.7. Diagnostic Licensed Products.

(a) Schering-Plough Licenses Third Party. In the event that Schering-Plough licenses a Third Party to Commercialize a Diagnostic Licensed Product, Schering-Plough shall pay to AVEO royalties on the proceeds of all Diagnostic Licensed Product Revenues in the Territory received by Schering-Plough for such a license based on the royalty table set forth in Section 7.6(a), with such Diagnostic Licensed Product Revenues being deemed to be Net Sales. Such royalties shall be payable (a) with respect to royalties received by Schering-Plough, its Affiliates or Sublicensees for the period set forth in Section 7.6(c), and any such royalties shall be subject to, where applicable, reductions set forth in the second sentence of Section 7.6(c); and (b) with respect to all other amounts received by Schering-Plough or any of its Affiliates from any Third Party (including a Sublicensee) in connection with the sale or other disposition of Diagnostic Licensed Products or rights relating thereto, for so long as Schering-Plough receives such amounts.

7.14. Blocked Payments. If by reason of applicable Laws in any country in the Territory, it becomes impossible or illegal for Schering-Plough or its Affiliates or Sublicensees to transfer, or have transferred on its behalf, milestones, royalties or other payments to AVEO, Schering-Plough shall promptly notify AVEO of the conditions preventing such transfer and such royalties or other

-32-

-38-

protecting its own confidential and proprietary information. Each Party will be responsible for a breach of this Article IX by its Agents. For clarity, each Party may disclose Confidential Information of the other Party (a) to Regulatory Authorities (i) to the extent desirable to obtain or maintain INDs or Regulatory Approvals for any Licensed Product within the Territory and (ii) in order to respond to inquiries, requests or investigations by Regulatory Authorities; (b) to outside consultants, scientific advisory boards, managed care organizations, and non-clinical and clinical investigators to the extent necessary to Develop or Commercialize any Licensed Product (provided that such Party shall obtain the same confidentiality obligations from such Third Parties as it obtains with respect to its own similar types of confidential information); and (c) to the extent desirable to obtain Patent Rights to protect, or to Develop or Commercialize, any Licensed Product.

9.2. Publication Rights. Each Party agrees that it shall not, and shall cause its Affiliates and its and their Affiliates’ employees, consultants, contractors, licensees and agents not to, publish or publicly present any results of any preclinical or clinical studies with respect to any Licensed Product without the prior consent of the other Party (which shall not be unreasonably withheld), except as may be required by applicable Law, legal proceedings or for patent filings. Each Party acknowledges that the other Party has an interest in the publication of studies related to Licensed Products conducted by itself and its collaborators, and agrees that the JSC will be responsible for determining which publications of this nature can occur without prejudice to the interests of the other Party. Subject to the foregoing, each Party shall provide to the other Party the opportunity to review any proposed abstracts, manuscripts or summaries of presentations that disclose any Confidential Information or results of preclinical or clinical studies with respect to any Licensed Product at least forty-five (45) days prior to the submission of such proposed abstract, manuscript or summary for publication or presentation. The reviewing Party shall have the right: to propose modifications to the proposed disclosure; to prohibit or delay the proposed disclosure for patent reasons, trade secret reasons or business reasons; or to request a reasonable delay in publication or presentation in order to protect patentable information. If the reviewing Party requests a delay, the publishing Party shall delay submission or presentation for a period of up to ninety (90) days to enable patent applications protecting each Party’s rights in such information to be filed. If the reviewing Party requests modifications to the proposed disclosure, the publishing Party shall edit the proposed disclosure pursuant to the reviewing Party’s request prior to its submission. If the reviewing Party prohibits publication, the publishing Party shall not publish the public presentation during the Term of this Agreement. With respect to any proposed abstracts, manuscripts or summaries for publication or presentation by investigators or other Third Parties, such materials shall be subject to review in accordance with the terms and conditions of the clinical trial agreement entered into by a Party with such Third Party; provided that such clinical trial agreement has been approved in writing in advance by the JSC in accordance with Section 8.1(d)(i) & (ii).

9.3. Public Disclosure.

(a) The terms and conditions of this Agreement are Confidential Information hereunder and, except as expressly set forth herein, the Parties shall not disclose any terms or conditions of this Agreement to any Third Party without first obtaining the written approval of the other Party prior to such disclosure. Additionally, the Parties shall not use any name or trademark of the other Party in any publicity without the prior written approval of the other Party. After the Execution Date, AVEO may issue one or more press releases, subject to the prior approval of Schering-Plough, such approval not to be unreasonably withheld, delayed or conditioned.

-39-

(b) Neither Party shall issue any additional press release or make any other public disclosure concerning this Agreement or the subject matter hereof without first following the approval procedure of this Section 9.3(b). The disclosing Party shall provide the other Party with a copy of the proposed release or public disclosure for review and comment as soon as reasonably practicable prior to the proposed disclosure date; provided that such right of review and comment shall only apply for the first time that specific information is to be disclosed, and shall not apply to the subsequent disclosure of the same specific information that has previously been approved for disclosure. The Party proposing to make the press release or other public disclosure shall give due consideration to any reasonable comments by the other Party relating to such proposed press release or other public disclosure. The principles to be observed by Schering-Plough and AVEO in press releases or other public disclosures with respect to this Agreement shall be: accuracy, compliance with applicable legal requirements and the requirements of confidentiality under Article IX. For the avoidance of doubt, either Party may issue such press releases as it determines, based on the reasonable advice of counsel, are reasonably necessary to comply with Law. It is understood, however, that except as provided in Section 9.3(c), or unless required by Law in the reasonable opinion of counsel, the Parties shall not disclose the specific financial terms and conditions of this Agreement, any plans, projections or forecasts for clinical trials, regulatory approval, marketing or Commercialization of Licensed Product or other non-factual or speculative information in any press release or other public disclosure. In addition, if a public disclosure is required by Law in the reasonable opinion of counsel, including without limitation in a filing with the United States Securities and Exchange Commission, the disclosing Party shall provide copies of the proposed disclosure in advance (as set forth herein) of such filing or other disclosure for the non-disclosing Party’s prior review and comment and shall give due consideration to any reasonable comments by the non-filing Party relating to such filing, including without limitation the provisions of this Agreement for which confidential treatment should be sought. In the event a Party believes that it is required by Law to make a disclosure under this Section 9.3(b) and the non-disclosing Party disagrees with such conclusion, the Parties shall, through their attorneys, discuss and seek to resolve such disagreement.

(c) Notwithstanding any other provisions to the contrary in this Article IX, each Party shall be entitled to disclose the terms (including the financial terms) of this Agreement to a Party’s or its Affiliates’ accountants and attorneys on the condition that such entities or persons agree to keep such terms confidential for the same time periods and to the same extent as such Party is required to keep such terms confidential. Subject to the prior written approval of Schering-Plough, not to be unreasonably withheld, AVEO may disclose the terms of this Agreement to its other professional financial advisors and any existing or potential bona fide acquirers, investors or lenders on the condition that such entities or persons agree to keep such terms confidential for the same time periods and to the same extent as AVEO is required to keep such terms confidential. For the sake of clarity, Schering-Plough may only withhold such approval if there is a good faith disagreement between the Parties over whether a Third Party to whom AVEO is proposing to make the disclosure satisfies the requirements of this Section 9.3(c).

(a) If a Party or any of its Affiliates or their respective employees or agents (collectively, the “Indemnitee”) intends to claim indemnification under Section 11.2 or 11.3, the Indemnitee shall promptly notify the other Party (the “Indemnitor”) of any loss, claim, damage, liability or action in respect of which the Indemnitee intends to claim such indemnification, and the Indemnitor shall assume the defense thereof with counsel selected by the Indemnitor and reasonably acceptable to the Indemnitee; provided, however, that an Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitee, if representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing interests between such Indemnitee and any other Party represented by such counsel in such proceedings. The Indemnitor shall have the right to settle or compromise any claims for which it is providing indemnification under this Section 11.3; provided that the consent of the Indemnitee (which shall not be unreasonably withheld or delayed) shall be required in the event any such settlement or compromise would adversely affect the interests of the Indemnitee. The indemnity agreement in this Section 11.3 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the consent of the Indemnitor. The failure to deliver notice to the Indemnitor within a reasonable time after the commencement of any such action, if prejudicial to the Indemnitor’s ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Section 11.3 resulting from such failure, but the omission so to deliver notice to the Indemnitor will not relieve it of any liability that it may have to any Indemnitee otherwise than under this Section 11.3.

11.4. Insurance. Each Party shall maintain appropriate product liability insurance (and/or self-insurance) with respect to its Research, Development, Manufacture and Commercialization activities hereunder in such amount as such Party customarily maintains with respect to its other products.

11.5. Exclusive Remedy. The Parties agree and acknowledge that the provisions of this Article XI represent the Indemnified Party’s exclusive recourse with respect to any Losses for which indemnification is provided to the Indemnified Party under this Article XI.

ARTICLE XII. TERM AND TERMINATION

12.1. Term. The term of this Agreement (the “Term”) shall, unless earlier terminated as provided in this Article XII, shall continue in full force and effect, on a country-by-country and Licensed Product-by-Licensed Product basis until there is no remaining royalty obligation in such country with respect to such Licensed Product, at which time this Agreement shall expire in its entirety with respect to such Licensed Product in such country. The Term shall expire on the date the Agreement has expired with respect to all Licensed Products in all countries in the Territory.

12.2. Termination Due to Passage of Time. Either Party may terminate this Agreement effective upon notice to the other Party if the HSR Clearance Date shall not have occurred on or prior to the date one hundred and twenty (120) days after the Parties make their respective HSR Filings pursuant to Section 14.1. If this Agreement is terminated pursuant to this Section 12.2, then this Agreement, including Section 12.10 of this Agreement, shall terminate; provided, however, that the Confidentiality Agreement and the AVEO/SP Material Transfer Agreement shall remain in full force and effect notwithstanding any termination of this Agreement pursuant to this Section 12.2.

-46-

12.3. Schering-Plough Termination at Will. Schering-Plough shall have the right to terminate this Agreement upon ninety (90) days written notice to AVEO.

12.4. Termination for Cause. In the event of a Material Breach of this Agreement by a Party, the other Party may give the Party in default written notice requiring it to cure such default. “Material Breach” shall mean a failure by a Party to perform one or more of its obligations under this Agreement that, if not cured within the applicable cure period, is likely to cause material harm to the other Party. Without limiting the generality of the foregoing, such material harm shall be deemed to have occurred if the breach causes or is likely to cause a material adverse effect on the global commercial value of a Licensed Product and to materially impair the ability of the non-breaching Party to realize the reasonably anticipated benefits of the global commercialization of a Licensed Product. If such Material Breach is not cured within [**] days after receipt of such notice (or within [**] days in the case of a payment breach), the notifying Party shall be entitled (without prejudice to any of its other rights conferred on it by this Agreement or under applicable Law) to terminate this Agreement (or such rights and obligations as are set forth in Section 12.8(b)) by giving written notice to the defaulting Party, with such termination to take effect immediately. Notwithstanding the foregoing, if the Material Breach relates only to a specific Licensed Product in a specific country or group of countries then any termination pursuant to this Section 12.4 shall apply only to the affected Licensed Product or countries. Termination of this Agreement pursuant to this Section 12.4 shall automatically be stayed pending the outcome of any dispute resolution proceedings initiated pursuant to Article XIII that relate to the subject matter of such termination. The right of either Party to terminate this Agreement as set forth in this Section 12.4 shall not be affected in any way by its waiver of, or failure to take action with respect to, any previous default. If AVEO terminates this Agreement under this Section 12.4, then the consequences set forth in Section 12.6 shall apply for each affected Licensed Product and in each affected country. If Schering-Plough terminates this Agreement under this Section 12.4, then the consequences set forth in Section 12.8 shall apply.

12.5. Termination for Insolvency.

-47-

(d) anything analogous to any of the foregoing occurs in any applicable jurisdiction. Termination shall be effective upon the date specified in such notice. If AVEO terminates this Agreement under this Section 12.5, then the provisions of Section 12.6 shall apply.

15.4. Entire Agreement. This Agreement (including Exhibits and Schedules) contains the complete understanding of the Parties with respect to the Development, Manufacture and Commercialization of Licensed Products and supersedes all prior understandings and writings relating to such subject matter. In particular, and without limitation, it supersedes and replaces the Confidentiality Agreements, the AVEO/SP Material Transfer Agreement and any and all term sheets relating to the transactions contemplated by this Agreement and exchanged between the Parties prior to the Execution Date. No amendment change or addition to this Agreement will be effective or binding on either Party unless reduced to writing and duly executed on behalf of both Parties.

15.5. Headings. Headings in this Agreement are for convenience of reference only and shall not be considered in construing this Agreement.

15.6. Severability. If any provision of this Agreement is held unenforceable by a court or tribunal of competent jurisdiction because it is invalid or conflicts with any Law of any relevant jurisdiction, the validity of the remaining provisions shall not be affected. In such event, the Parties shall negotiate a substitute provision that, to the extent possible, accomplishes the original business purpose.

15.7. Registration and Filing of the Agreement. To the extent a Party determines in good faith that it is required by applicable Law to publicly file, register or notify this Agreement with a Regulatory Authority, including public filings pursuant to securities Laws, it shall provide the proposed redacted form of the Agreement to the other Party a reasonable amount of time, not less than five (5) Business Days, prior to filing for the other Party to review such draft and propose changes to such proposed redactions.

Further, each Party may assign this Agreement, without the prior written consent of the other Party, to its successor in interest by way of merger, acquisition, or sale of all or substantially all of its assets to which this Agreement relates; provided, that such Party provides the other Party with written notice of such assignment; and provided further, if the Third Party that acquires or controls AVEO or AVEO’s assets, as the case may be, following such a transaction is a Major Pharmaceutical Company (as defined below), then, upon written notice by Schering-Plough, AVEO’s Co-Promotion Option pursuant to Section 5.2 and the provisions of Article 5 of this Agreement (other than Schering-Plough’s obligation to use Commercially Reasonable Efforts to Commercialize Licensed Product in the Major Markets) shall terminate immediately.

-55-

Any other assignment of this Agreement by a Party requires the prior written consent of the other Party. Any assignment in violation of this Section 15.8 shall be null and void. This Agreement shall be binding on and shall inure to the benefit of the permitted successors and assigns of the Parties hereto. Notwithstanding the foregoing, in the event that a Party assigns this Agreement to its successor in interest by way of merger, acquisition, or sale of all or substantially all of its assets to which this Agreement relates, the intellectual property rights of such successor in interest, and of any of its Affiliates as of just prior to such assignment, as existing immediately prior to the closing of such transaction, shall be automatically excluded from the rights licensed to the non-assigning Party under this Agreement. For purposes of this Section 15.8, “Major Pharmaceutical Company” means a Third Party company (including a pharmaceutical or biotech company or a “group” within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934; but excluding Schering-Plough and any Affiliates of the Parties) whose worldwide net sales (or reported equivalent) of human pharmaceutical products in the most recently completed fiscal year for which audited financial statements are publicly available exceed [**] US Dollars or whose net sales in the US of human pharmaceutical products in the most recently completed fiscal year for which audited financial statements are publicly available exceed [**] US Dollars, as reported in such financial statements, or if not publicly available as provided by AVEO.

15.11. Non-Solicitation of Employees. During the Research Program Term, neither Party shall directly recruit or solicit any employee of the other Party, who is then a current employee of the other Party, with whom such Party has come into contact or interacted with for the purpose of performing this Agreement, without the prior consent of the other Party, except pursuant to general solicitations not targeted specifically at such employees or in response to unsolicited employment inquiries by such employees.

15.12. Third-Party Beneficiaries. None of the provisions of this Agreement shall be for the benefit of or enforceable by any Third Party other than an indemnitee under Article XI. No such Third Party shall obtain any right under any provision of this Agreement or shall by reason of any such provision make any claim in respect of any debt, liability or obligation (or otherwise) against either Party.

15.13. Relationship of the Parties. Each Party shall bear its own costs incurred in the performance of its obligations hereunder without charge or expense to the other, except as expressly provided in this Agreement. Neither Party shall have any responsibility for the hiring, termination or compensation of the other Party’s employees or for any employee compensation or benefits of the other Party’s employees, other than as provided in Section 3.2(a). No employee or representative of a Party shall have any authority to bind or obligate the other Party for any sum or in any manner whatsoever, or to create or impose any contractual or other liability on the other Party without said other Party’s approval. For all purposes, and notwithstanding any other provision of this Agreement to the contrary, the legal relationship under this Agreement of each Party to the other Party shall be that of independent contractor. Nothing in this Agreement shall be construed to establish a relationship of partners or joint venturers between the Parties.

15.14. Performance by Affiliates. To the extent that this Agreement imposes obligations on Affiliates of a Party, such Party agrees to cause its Affiliates to perform such obligations.

15.15. Construction. Each Party acknowledges that it has been advised by counsel during the course of negotiation of this Agreement, and, therefore, that this Agreement shall be interpreted without regard to any presumption or rule requiring construction against the Party causing this Agreement to be drafted. Any reference in this Agreement to an Article, Section, subsection, paragraph, clause, Schedule or Exhibit shall be deemed to be a reference to any Article, Section, subsection, paragraph, clause, Schedule or Exhibit, of or to, as the case may be, this Agreement.

Based on the Applicable Percentage, the Co-Promotion Agreement shall be structured to reflect the following:

• The allocation of details for the Co-Promotion Indication will be reasonably allocated between the Parties, taking into consideration prescribing levels, target audience for the Co-Promotion Indication, geographic territory, centers of excellence and other considerations as decided by the JCC. In all cases the Parties agree that the allocation of the details should be done in a manner to minimize any duplication of effort by the Parties. [**].

• Each year Schering-Plough may increase or decrease the overall sales force effort for the Licensed Product for the Co-Promotion Indication. If Schering-Plough increases such sales force efforts, AVEO shall have the right, but not the obligation, to increase its total sales force efforts within [**] days of receipt of notice from Schering-Plough in order to maintain its Applicable Percentage, provided that if AVEO does not increase its total sales force efforts, its Applicable Percentage shall be reduced to reflect the level of sales efforts maintained by AVEO. If Schering-Plough decreases such sales force efforts, AVEO shall adjust its sales force efforts to perform its Applicable Percentage unless Schering-Plough agrees otherwise.

• Schering-Plough will compensate AVEO for co-promoting the Licensed Product [**].

• AVEO shall employ its expertise, best professional judgment and, where applicable, its working relationships with the target audience and other physician specialties, as applicable, to ensure that AVEO’s sales force used for the promotion of the Licensed Product (the “AVEO Sales Force”) details the Licensed Products in a manner aimed at maximum appropriate prescription generation. In connection with AVEO’s management of the AVEO Sales Force, AVEO shall designate its own full-time employee as a senior director of sales (or functional equivalent), who shall be AVEO’s primary contact with Schering-Plough relating to the AVEO Sales Force.

• [**].

• Hiring Criteria. AVEO shall ensure that each member of the AVEO Sales Force meets an agreed upon Hiring Criteria throughout the term of the Co-Promotion Agreement, provided such hiring criteria is no more stringent than Schering-Plough’s hiring criteria for its own sale force for the Licensed Product. Hiring Criteria shall mean that (i) at least [**] percent ([**])% of the Sales Force shall have [**] or more years of experience in promoting prescription pharmaceutical products, of which [**] must have been spent promoting to hospitals and specialty care physicians; and (ii) at least [**] percent ([**])% of the Sales Force shall have at least [**] of experience in promoting prescription pharmaceutical oncology products.

Such notice will not be effective unless the results of the study meet the study’s primary end point. Once such notice is effective, all current and future Co-Promotion activities (or options to Co-Promote) will terminated.

During the term of the Co-Promotion Agreement, AVEO will maintain a Disclosure Program that includes a mechanism (e.g., a toll-free compliance telephone line) to enable individuals to disclose, to the Compliance Officer or some other person who is not in the disclosing individual’s chain of command, any identified issues or questions associated with AVEO’s policies, Schering-Plough’s Standards of Global Business Practices and Schering-Plough’s U.S. Sales and Marketing Policy, conduct, practices, or procedures with respect to a Federal health care program or FDA requirement believed by the individual to be a potential violation of criminal, civil, or administrative law. The Compliance Officer shall conduct an internal review of any matter brought to the attention of AVEO that a reasonable person would consider a probable violation of criminal, civil, or administrative laws relating to the promotion of the Licensed Product. AVEO shall report to Schering-Plough on the results on the Compliance Officer’s internal review. During the term of the Co-Promotion Agreement, AVEO shall appropriately publicize the existence of the disclosure mechanism (e.g., via periodic e-mails to employees or by posting the information in prominent common areas, including on the company’s intranet or internal web site available to all employees).

• The Disclosure Program shall emphasize a non-retribution, non-retaliation policy, and shall include a reporting mechanism for anonymous communications for which appropriate confidentiality shall be maintained. Upon receipt of a disclosure associated with AVEO’s policies, Schering-Plough’s Standards of Global Business Practices and Schering-Plough’s U.S. Sales and Marketing Policy, conduct, practices or procedures with respect to any Federal health care program, Federal health care program requirement or FDA requirement concerning the promotion of products (hereafter “Disclosure”), the Compliance Officer shall gather all relevant information from the disclosing individual. The Compliance Officer shall make a preliminary, good faith inquiry into the allegations set forth in every Disclosure to ensure that he or she has obtained all of the information necessary to determine whether a further review should be conducted. For any Disclosure that is sufficiently specific so that it reasonably: (1) permits a determination of the appropriateness of the alleged improper practice; and (2) provides an opportunity for taking corrective action, AVEO shall conduct an internal review of the allegations set forth in the Disclosure and ensure that proper follow-up is conducted.

• The Compliance Officer shall maintain a Disclosure log, which shall include a record and summary of each Disclosure received (whether anonymous or not), the status of the respective internal reviews, and any corrective action taken in response to the internal reviews. The Disclosure log shall be made available to Schering-Plough, upon request.

Exh. C-7

• AVEO shall maintain policies and procedures relating to compensation (including salaries and bonuses) for the AVEO Sales Force that are designed to ensure that financial incentives do not exist for the improper promotion, sales, and marketing of the Licensed Product and disciplinary policies and procedures for violations of AVEO’s policies and procedures, including policies relating to Federal health care program and FDA requirements.

15. Miscellaneous.

• Nothing in the Co-Promotion Agreement shall give AVEO the right to conduct or otherwise participate in any clinical trials relating to the Licensed Product.

• The Parties shall agree to appropriate and reasonable audit, recordkeeping and reporting obligations (including monthly and biweekly performance reports).
