In the event the Royalty-bearing Product is sold as part of a Combination Product (as defined below), the Net Sales from the Combination Product, for the purposes of determining royalty payments, shall be determined by multiplying the Net Sales of the Combination Product (as defined in the standard Net Sales definition), during the applicable royalty reporting period, by the fraction, A/A+B where A is the average sale price of the Royalty-bearing Product when sold separately in finished form and B is the average sale price of the other product(s) included in the Combination Product when sold separately in finished form, in each case during the applicable royalty reporting period or, if sales of both the Royalty-bearing Product and the other product(s) did not occur in such period, then in the most recent royalty reporting period in which sales of both occurred. In the event that such average sale price cannot be determined for both the Royalty-bearing Product and all other product(s) included in the Combination Product, Net Sales for the purposes of determining royalty payments shall be calculated by multiplying the Net Sales of the Combination Product by the fraction C/C+D where C is the fair market value of the Royalty-bearing Product and D is the fair market value of all other pharmaceutical product(s) included in the Combination Product. In such event, AHP shall in good faith make a determination of the respective fair market values of the Royalty-bearing Product and all other pharmaceutical products included in the Combination Product, and shall notify Millennium of such determination and provide Millennium with data to support such determination. Millennium shall have the right to review such determination and supporting data, and to notify AHP if it disagrees with such determination. If Millennium does not agree with such determination and the Parties are unable to agree in good faith as to such respective fair market values, then such matter shall be referred to the Executive Officers (as defined in Section 2.3(b)(iii) pursuant to Section 2.3(b)(iv)). - 10 - 17 As used above, the term "Combination Product" means any pharmaceutical product which comprises the Royalty-bearing Product and other active compounds and/or ingredients.

(iv) Rejected Millennium Reserve Field Project. In the event that (A) a Reserve Field Project is submitted to the CNS JMT by Millennium (a "Millennium Reserve Field Project") and (B) (1) the Steering Committee, or if necessary, the Executive Officers decide(s) that such Millennium Reserve Field Project does not have merit and, accordingly, should not be incorporated into the Research Program (and no alternative project targeting the disease that is the subject of such Millennium Reserve Field Project is identified pursuant to the terms of Section 2.4(b)(i)), (2) the Steering Committee or, if necessary, the Executive Officers decide(s) that such Millennium Reserve Field Project should be incorporated into the Research Program with increased funding but the funds available through the use of the Mutual Consent Fund have been exhausted and AHP does not agree to provide the recommended additional funding, or (3) neither the Management Committees nor the Executive Officers can reach a decision with respect to the proposed incorporation of such Millennium Reserve Field Project into the Research Program, then the disease that is the subject of such rejected Millennium Reserve Field Project (a "Rejected Millennium Reserve Field Project") shall cease to be a part of the Reserve Field and shall become part of the Expansion Field (see Section 2.4(c)). The specific Rejected Millennium Reserve Field Project shall be deemed a Rejected Expansion Field Project (see Section 2.4(c)) and shall be handled accordingly. For the sake of clarity, a disease can cease to be a part of the Reserve Field and become a part of the Expansion Field only if such disease is the subject of a Rejected Millennium Reserve Field Project. - 29 - 36 CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.

Section 2.5. Term of the Millennium Research Program; Extension Benchmarks. (a) Millennium shall conduct the Millennium Research Program for the first seven (7) Contract Years; provided, however, that AHP may terminate the Millennium Research Program by providing notice to Millennium (the "Termination Notice") (i) at any time during the ten (10) Business Day - 31 - 38 CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION. ASTERISKS DENOTE SUCH OMISSIONS. period following the conclusion of the third Contract Year, if, at the conclusion of the third Contract Year, the Year Three Extension Benchmark (as that term is defined below) has not been achieved, or (ii) at any time during the ten (10) Business Day period following the conclusion of the fifth Contract Year, if, at the conclusion of the fifth Contract Year, the Year Five Extension Benchmark (to be determined by the Steering Committee as described below) has not been achieved. As used herein, the term "Year Three Extension Benchmark" means that at least ************************* have been identified (i.e., have met the criteria for ****************** and ********************************** *********************************************************************** ********************************************************************* *********), provided that the foregoing criteria for the Year Three Extension Benchmark shall be subject to modification to be agreed upon in good faith based upon the prioritization of research within the Millennium Research Program (e.g., such criteria could include *************************** to the extent work thereon is contemplated by the Research Program Plan). In the event that the term of the Millennium Research Program is extended to at least five (5) Contract Years, the Year Five Extension Benchmark will be determined in good faith by the Steering Committee within ninety (90) days following the commencement of the fourth Contract Year. (b) If Millennium achieves the Year Three Extension Benchmark, then the Millennium Research Program shall continue for at least an additional two (2) Contract Years at the level of funding set forth in Budget 1 in Section 8.3(a) and, upon the election of Millennium, AHP shall make the required equity purchase set forth in Section 8.2. If Millennium fails to achieve the Year Three Extension Benchmark but AHP does not elect to terminate the Millennium Research Program as a result thereof, then the Millennium Research Program shall, at AHP's option and with no equity purchase by AHP pursuant to Section 8.2, continue for at least an additional two (2) Contract Years at the level of funding set forth for those Contract Years in Budget 2 in Section 8.3(a). The foregoing choice shall be made by AHP within ten (10) Business Days following the conclusion of the third Contract Year. In the event that AHP elects to extend the term of the Millennium Research Program pursuant to this Section 2.5(b) and Millennium achieves the Year Five Extension Benchmark, AHP shall be obligated, upon the - 32 - 39 election of Millennium, to make the equity purchase triggered by such achievement, as set forth in Section 8.2. (c) If the term of the Millennium Research Program is extended to at least five (5) Contract Years, and Millennium fails to achieve the Year Five Extension Benchmark but AHP does not elect to terminate the Millennium Research Program as a result thereof, then the Millennium Research Program shall, at AHP's option and with no equity purchase by AHP pursuant to Section 8.2, continue for the remaining two (2) Contract Years of the seven (7) Contract Year Term at the reduced level of funding set forth in Budget 2 in Section 8.3(a) if Millennium had not achieved the Year Three Extension Benchmark or Budget 3 in Section 8.3(a) if Millennium had achieved the Year Three Extension Benchmark. The foregoing choice shall be made by AHP within ten (10) Business Days following the conclusion of the fifth Contract Year. (d) If Millennium achieves both the Year Three Extension Benchmark and the Year Five Extension Benchmark, then the Millennium Research Program shall continue for the entire seven (7) Contract Year term at the funding level set forth in Budget 1 in Section 8.3(a) and AHP, at the election of Millennium, shall make both equity purchases set forth in Section 8.2. Section 2.6. Termination of the Millennium Research Program. In addition to the right of AHP to terminate the Millennium Research Program pursuant to Section 2.5 in the event that the Year Three Extension Benchmark or Year Five Extension Benchmark is not achieved, AHP shall have the following rights to terminate the Millennium Research Program: (a) Termination Upon Change of Control. AHP shall have the right to terminate the Millennium Research Program upon the occurrence of a Change of Control during the term of the Millennium Research Program by providing written notice of termination to Millennium within sixty (60) days following receipt of written notice of the occurrence of such Change of Control. Millennium agrees to provide AHP with written notice of a Change of Control within ten (10) Business Days following the occurrence thereof. (b) Termination Upon a Change in Strategic Direction or a Technology Patent Blocking Event. AHP shall have the right to terminate the Millennium Research Program (i) upon the occurrence - 33 - 40 of a Change in Strategic Direction by providing written notice of termination to Millennium indicating its belief that such a Change in Strategic Direction has occurred and specifying its reasons for such belief, or (ii) in the event that a Technology Patent Blocking Event has occurred by providing written notice of termination to Millennium indicating its belief that a Technology Patent Blocking Event has occurred and specifying its reasons for such belief. Such termination shall be effective sixty (60) days following Millennium's receipt of any such notice unless Millennium, during such sixty (60) day period, objects in writing to such termination and provides reasons for its belief that a Change in Strategic Direction or a Technology Patent Blocking Event, as applicable, has not occurred. Any disagreement relating to the occurrence of a Change in Strategic Direction or a Technology Patent Blocking Event, as applicable, shall be resolved by the Executive Officers pursuant to Section 2.3(b)(iv) above.. (c) Termination Upon Certain Unsuccessful Technology Transfers. AHP shall have the right to terminate the Millennium Research Program during the period beginning on the first day of the fourth Contract Year and ending ninety (90) days thereafter in the event that (a) AHP has terminated the TPT Access and License Agreement and (i) AHP has made one or more requests for a transfer of MTPT, including a request for RADE (as such terms are defined in the TPT Access and License Agreement), and (ii) there has not occurred at least one (1) Successful Transfer (as defined in the TPT Access and License Agreement); or (b) AHP has terminated the software license agreement between Millennium and AHP effective as of August 1, 1996 (the "Bioinformatics Agreement") on the basis that Millennium failed to complete the initial installation of the Millennium Bioinformatics Technology in accordance with the Acceptance Criteria (as such terms are defined in the Bioinformatics Agreement). Any such termination shall be effected by written notice from AHP to Millennium provided during the ninety (90) day period specified above, and shall be effective sixty (60) days after such notice. (d) For the sake of clarity, the termination of the Millennium Research Program, pursuant to this Section 2.6, shall not constitute a termination of this Agreement. Section 2.7. Diligence.

Section 5.3. AHP's Right of First Refusal with Respect to Non-Vaccine Products. During the term of the Research Program, Millennium and AHP agree to discuss collaborations concerning the development and commercialization of Non-Vaccine Products for use in the CNS Disorders Field on a product-by-product basis. The initial opportunity to begin such discussions concerning a Non-Vaccine Product shall arise when, in the course of the Research Program, either Party recognizes the possibility for developing such Non-Vaccine Product. When this occurs, the Party recognizing such possibility shall present such information to the other Party and such other Party shall have a period of forty-five (45) days in which to initiate good faith negotiations concerning a potential collaboration with respect to such Non-Vaccine Product. If such negotiation is initiated, the Parties shall have a period of ninety (90) days in which to execute a definitive agreement, the terms and conditions of which shall govern any collaboration between the Parties with respect to such Non-Vaccine Product. If either (a) a negotiation concerning a potential collaboration with respect to a Non-Vaccine Product is not initiated, or (b) the Parties cannot agree to the terms of a - 40 - 47 collaboration with respect to such Non-Vaccine Product, then Millennium shall have the exclusive right, either alone or in collaboration with a third party, to research, have researched, develop, have developed, make, have made, import, use, have used, offer to sell, sell and have sold such Non-Vaccine Product for use in and outside of the CNS Disorders Field within the Territory, provided, however, that Millennium shall not, without AHP's prior written consent, enter into a collaboration with a third party with respect to such Non-Vaccine Product pursuant to an agreement, the terms and conditions of which are, on the whole, more favorable than those offered by Millennium to AHP. Notwithstanding the foregoing provisions of this Section 5.3, the Parties agree and acknowledge that Millennium shall have the right to enter into a collaboration with a commercial third party with respect to the research, development and/or commercialization of a broad class of Millennium therapeutic product opportunities that comprise Proteins ("Protein Therapeutics") and/or Gene Therapy Drugs, the significant majority of which are not likely to be useful as therapeutic products in the CNS Disorders Field; examples of such a class include without limitation: (i) Protein Therapeutics isolated from an individual cell or tissue type such as T cells or monocytes; (ii) Protein Therapeutics isolated from a set of several individual cell or tissue types; (iii) Protein Therapeutics of a specific structural or functional class such as chemokines; and (iv) Gene Therapy Drugs that contain a particular delivery vehicle that targets a broad set of cell or tissue types. Prior to entering into any such collaboration, Millennium shall provide AHP with (x) a written notification of its intent to enter into such collaboration, and (y) a written summary with respect to such collaboration (a "Collaboration Summary") broadly outlining the scope and the experimental objectives of the research to be undertaken in the course of such collaboration. Following a thirty (30) day period commencing on the date on which AHP receives the Collaboration Summary, Millennium shall have the right to enter into such collaboration, unless within such thirty (30) day period AHP provides Millennium with written notification of AHP's opinion that the collaboration described in the Collaboration Summary does not satisfy the conditions set forth in the first sentence of this paragraph, in which case the disagreement between the Parties with respect to such collaboration shall be presented to the Executive Officers for resolution within a period not to exceed thirty (30) days. With respect to any and all product opportunities falling within any class that is the subject of any collaboration with a commercial third party entered into by Millennium pursuant to this Section 5.3 that prohibits Millennium from collaborating with AHP - 41 - 48 with respect to such product opportunities, AHP's right of first refusal, as set forth in this Section 5.3, shall terminate. Section 5.4. AHP's Rights With Respect to Other Millennium Projects. The Parties understand and agree that during the term but outside of the Millennium Research Program, Millennium may undertake genomic research activities not designed primarily to yield biological molecules likely to be useful as therapeutic targets or as therapeutic products in the CNS Disorders Field but which may yield such biological molecules (the "Other Millennium Projects"). Other Millennium Projects include without limitation non-CNS disease-focused genetic/genomic research programs (e.g., studies of the genetic and molecular basis of obesity or asthma; random sequencing of cDNA libraries constructed from human or other tissues, such as T cells or fetal brain) and diagnostics research. In the event that (i) a biological molecule with utility as a target for small molecule intervention or a Vaccine in the CNS Disorders Field is identified in the course of an Other Millennium Project during the term of the Millennium Research Program, (ii) Millennium elects to exploit the potential of such biological molecule for use in the CNS Disorders Field, and (iii) Millennium has no prior commitment to a third party concerning the research, development and/or commercialization of such biological molecule that would prohibit Millennium from undertaking a collaboration with AHP with respect to such biological molecule, then Millennium shall (a) inform AHP of the existence and potential utility in the CNS Disorders Field of such biological molecule, and (b) enter into discussions with AHP regarding a collaboration between Millennium and AHP concerning the research, development and/or commercialization of such biological molecule within the CNS Disorders Field. Section 5.5. Diagnostic Products. The Parties acknowledge and agree that the development and commercialization of a Diagnostic Product associated with a Product may advantageously affect the sales of both the Diagnostic Product and the associated Product. Except as otherwise provided in this Section 5.5, Millennium has retained the right to develop and commercialize Diagnostic Products relating to Products, either alone or in collaboration with third parties. The Parties agree to exchange requisite information to enable Millennium, if it so elects, to develop a Diagnostic Product for use in conjunction with each Product and to enable AHP to assess the status of Millennium's development efforts relating thereto. Millennium shall provide written notice to AHP, on a disease indication-by-disease indication basis, whether it intends to develop a - 42 - 49 CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.

If (a) ************************************ ***************************************************************** ********************************************************** ************************, and the licences set forth in Sections 5.1 and 5.2 shall be extended to permit the development and commercialization of a Diagnostic Product for such indication; (b) **************************** ******************************************************************** ******************************************************************************* ************************************************************************* ************************************************************, then Millennium shall retain all rights with respect thereto, including the right to develop and commercialize such Diagnostic Product in collaboration with a third party, without obligation to AHP; (c) *************************************************************** ************************************************************** ****************************************************************** **************************************************** on the development and commercialization of such Diagnostic Product, then the Parties shall attempt in good faith to negotiate a separate development and commercialization agreement with respect to such Diagnostic Product, provided that *********************************************************************** ************************************************************************ ***********************************************************, including the right to develop and commercialize such Diagnostic Product in collaboration with a third party. In the event that ********** has not provided ********************** with respect to a specific disease indication, ****************************************** provide such notice within ***************; failure to provide such notice within ****************** shall be considered a response that ************************************************** ***************************. Section 5.6. AHP's Rights to Potential Candidate Genes. Within ninety (90) days following the expiration of the Research Program, AHP may designate any potential Candidate Gene as a Candidate Gene, provided, however, that at the time of such designation(s) AHP shall pay to Millennium the appropriate milestone payment set forth in Section 8.4. Upon any such designation(s), each designated Candidate Gene (a "Designated Candidate Gene") shall be subject to all terms and conditions of this Agreement that relate to any Candidate Gene. - 43 - 50 CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION. ASTERISKS DENOTE SUCH OMISSIONS. Section 5.7. AHP's Right of First Refusal with Respect to Autoimmune Diseases. (a) Program Discussion Initiated by Millennium. In the event that p***********************, Millennium has not entered into an agreement with a third party relating to the research, development and commercialization of products for Autoimmune Diseases, Millennium grants to AHP a right of first refusal on or after *************** to (a) fund any research program in which genetics and genomics technologies are used to discover genes responsible for susceptibility to Autoimmune Diseases (which genes may, in turn, be used to identify and develop Small Molecules and Vaccines for use in the field of Autoimmune Diseases) that Millennium has decided to undertake using financial support from a commercial third party (an "Autoimmune Disease Program"), and (b) obtain certain license rights under certain intellectual property that results from such Autoimmune Disease Program. Such right of first refusal shall continue for the term of the Research Program and shall operate as follows: (1) Millennium shall send to AHP a written notification describing in reasonable detail any such Autoimmune Disease Program contemplated by Millennium (an "AD Notification"); (2) AHP shall respond to Millennium within forty-five (45) days of its receipt of such AD Notification indicating its interest in such Autoimmune Disease Program; and (3) If AHP indicates that it is interested in funding such Autoimmune Disease Program, the Parties shall negotiate in good faith a reasonable agreement concerning such Autoimmune Disease Program. In the event that (X) AHP fails to respond to Millennium within forty-five (45) days after its receipt of an AD Notification, or (Y) AHP indicates that it is not interested in funding such Autoimmune Disease Program, or (Z) the Parties fail to reach a final agreement within ninety (90) days after the receipt by Millennium of AHP's response indicating AHP's interest in such Autoimmune Disease Program, Millennium shall be free to pursue such Autoimmune Disease Program with one or more third parties. If AHP gives notice of its intention to fund such Autoimmune Disease Program but the Parties fail to reach agreement and Millennium pursues a collaboration in the field of Autoimmune Diseases pursuant to an agreement with a commercial third party, Millennium agrees that the terms and conditions of any such agreement with any commercial third party shall not be, on the - 44 - 51 CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION. ASTERISKS DENOTE SUCH OMISSIONS. whole, more favorable than the most favorable terms offered to AHP. From and after ***************, Millennium shall not discuss any Autoimmune Disease Program with a commercial third party until after Millennium has provided AHP with an AD Notification with respect to such Autoimmune Disease Program. (b) Program Discussions with a Third Party. Notwithstanding the provisions set forth in Section 5.7(a), if a discussion of an Autoimmune Disease Program is already in progress between Millennium and a commercial third party as of *************** or is initiated by a commercial third party after *************** but during the term of the Research Program, Millennium shall promptly inform AHP of such third party interest. In such instance, Millennium shall have the right to continue its discussions with such third party but hereby agrees to initiate concurrent good faith negotiations with AHP with respect to such research program. Section 5.8. Millennium's Retained Rights. Any of Millennium's rights to Millennium Program Know-How and Millennium Program Patent Rights not specifically licensed to AHP pursuant to this Article V shall be retained by Millennium, including without limitation (a) Millennium's non-exclusive right to research, have researched, develop, have developed, make, have made, import, use, have used, offer to sell, sell and have sold Small Molecules and Vaccines for use in the treatment of medical indications outside of the CNS Disorders Field within the Territory, provided that, except as otherwise specifically provided herein or in the TPT Access and License Agreement, Millennium shall have no rights to AHP products or compounds, (b) Millennium's exclusive right to research, have researched, develop, have developed, make, have made, import, use, have used, offer to sell, sell and have sold any (i) Non-Vaccine Product (subject to AHP's right of first refusal as set forth in Section 5.3), (ii) Diagnostic Product (subject to the provisions of Section 5.4), and (iii) Antisense Drug that embodies Millennium Program Know-How, in each case, for use in and outside of the CNS Disorders Field within the Territory, and (c) Millennium's exclusive right, within the Territory, to practice, outside of the CNS Disorders Field, any and all Millennium Program Know-How that does not constitute a Validated Target or Validated Vaccine Candidate. - 45 - 52 Article VI Patent Ownership, Protection and Related Matters Section 6.1. Ownership. AHP shall own all inventions within the scope of the Research Program or the AHP Discovery Program made solely by its employees, and Millennium shall own all inventions within the scope of the Research Program made solely by its employees.

All patent applications and patents covering any invention and all Know-How related to such invention made within the scope of the Research Program or the AHP Discovery Program shall be owned by the Parties or Party, as the case may be, that own(s) said invention. The determination of inventorship shall be made in accordance with relevant patent laws; in the event of a dispute regarding inventorship, the Steering Committee shall be authorized to determine inventorship, with the advice of mutually acceptable outside patent counsel not regularly employed by either Party. Section 6.2. Patentable Inventions. (a) If a patentable invention related to the Core Field is (i) conceived or reduced to practice prior to the Effective Date and included within Millennium Program Patent Rights, or (ii) conceived in the course of and within the scope of the Research Program and is reduced to practice within the course of the Research Program or the AHP Discovery Program (with respect to either subsection (i) or (ii), a "Section 6.2 Invention"), AHP and Millennium shall promptly discuss that invention and the desirability of filing a United States patent application covering such invention, as well as any foreign counterparts. The Party owning the Section 6.2 Invention (determined in accordance with Section 6.1) shall make the final decision with respect to any such filings as soon as practicable. If a Section 6.2 Invention is made jointly, the CNS JMT shall determine which Party shall file and prosecute the application. If either (1) the CNS JMT is unable to make such a determination or (2) no decision is made regarding which Party shall file and prosecute the application covering such jointly owned invention, then (i) Millennium shall have the first option to file and prosecute the application - 46 - 53 for such jointly owned invention if such invention relates to a Candidate Gene, Validated Target, Validated Vaccine Candidate, Protein, Gene Therapy Drug or Diagnostic Product, and (ii) AHP shall have the first option to file and prosecute the application for such jointly made invention if such invention relates to a Modified Drug, Small Molecule Product or Vaccine Product. In the event that either Party declines the option to file and prosecute any such patent application for such jointly made invention, the Party not having such option may, upon written notice to the other Party, file and prosecute the application for such jointly made inventions. (b) Patent applications relating to Section 6.2 Inventions made jointly shall be prepared and prosecuted by outside patent counsel mutually agreed to by the Parties, with review and comment provided by both Parties as to such preparation and prosecution.

Section 6.3. Review and Comment. Each Party shall provide the other Party with a copy of any patent application which first discloses any Section 6.2 Invention prior to filing the first of such applications in any jurisdiction, if possible, for review and comment by such other Party. The Party receiving any such patent application under this Section 6.3 shall maintain such patent application in confidence, pursuant to Article IV. Section 6.4. Notice of Decision. If a Party decides not to file, prosecute or maintain an application or patent on a Section 6.2 Invention in any country, it shall give the other Party reasonable notice to this effect. After such notice, the other Party may file, or maintain the application or patent, in which event the first Party shall execute such documents and perform such acts as may be reasonably necessary for the other Party to file, prosecute or maintain such application. Section 6.5. Patent Term Extensions. The Parties shall cooperate, if necessary and appropriate, with each other in gaining patent term extension wherever applicable to Program Patent Rights covering Products. The Parties shall, if necessary and appropriate, use reasonable efforts to agree upon a joint strategy relating to patent term extensions, but, in the absence of mutual agreement with respect to any extension issue, a patent shall be extended if either Party elects to extend such patent. - 47 - 54 CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION. ASTERISKS DENOTE SUCH OMISSIONS. All filings for such extension shall be made by the Party to whom the patent is assigned, provided, however, that in the event that the Party to whom the patent is assigned elects not to file for an extension, such Party shall (i) inform the other Party of its intention not to file and (ii) grant the other Party the right to file for such extension. Section 6.6. Costs and Expenses. Each Party shall bear its own costs and expenses in filing, prosecuting, maintaining and extending Patent Rights arising out of the Research Program and the AHP Discovery Program, except that AHP shall reimburse Millennium for ******************* of the costs of filing, prosecuting, maintaining and extending Millennium Program Patent Rights and Joint Program Patent Rights incurred on and after the Effective Date. AHP shall, however, have the right to decline to so reimburse Millennium with respect to a Millennium Program Patent Right in any country or countries in the Territory by so notifying Millennium in writing prior to the time that Millennium incurs legal expenses with respect to such Millennium Program Patent Right, in which event the licenses granted to AHP in Article V with respect to such Millennium Program Patent Right in such country or countries shall terminate, unless otherwise agreed in writing. Section 6.7. Third Party Infringement. (a) Millennium and AHP each agrees to take reasonable actions to protect the Program Patent Rights from infringement in the CNS Disorders Field and to protect the Program Know-How from unauthorized use in the CNS Disorders Field, when, from its own knowledge or upon notice by the other Party, the Party with knowledge or receiving notice becomes aware of the reasonable probability that such infringement or unauthorized use exists in the Field. (b) Within ninety (90) days of becoming aware of the reasonable probability of an interference or infringement of the Program Patent Rights in the CNS Disorders Field or unauthorized use of the Program Know-How in the CNS Disorders Field, the Responsible Party (as defined below) shall decide whether to institute an infringement suit or take other appropriate action that it believes is reasonably required to protect the Program Patent Rights and Program Know-How in the CNS Disorders Field. If the Responsible Party fails to institute such suit or take such action within such ninety (90)-day period, then the other Party shall have the right at its sole discretion to institute such suit or other appropriate action in the name of either or both Parties. - 48 - 55 CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION. ASTERISKS DENOTE SUCH OMISSIONS. In such event, the Responsible Party shall cooperate with the other Party to the extent reasonably possible, including the joining of suit if necessary or desirable. (c) Neither Party shall settle or compromise any claim or proceeding relating to Program Patent Rights or Program Know-How in the CNS Disorders Field without the consent of the other Party, which consent shall not be unreasonably withheld, provided that no such consent of Millennium shall be required with respect to Patent Rights owned by, licensed to or otherwise controlled by AHP (other than Millennium Program Patent Rights). (d) As used herein, the term "Responsible Party" means (i) AHP with respect to Patent Rights solely owned by, licensed to or otherwise controlled by AHP (other than Millennium Program Patent Rights), (ii) Millennium with respect to Millennium Program Patent Rights and (iii) AHP and Millennium jointly with respect to Joint Program Patent Rights. (e) Each Party shall assume and pay all of its own out-of-pocket costs incurred in connection with any litigation or proceedings described in this Section 6.7, including, without limitation, the fees and expenses of that Party's counsel. (f) Any recovery obtained by any Party as a result of any proceeding described in this Section 6.7 or from any counterclaim or similar claim asserted in a proceeding described in Section 6.9, by settlement or otherwise, shall be applied in the following order of priority: (i) first, to reimburse each Party for all litigation costs in connection with such proceeding paid by that Party and not otherwise recovered on a pro rata basis based on each Party's respective litigation costs; and (ii) second, the remainder of the recovery shall be paid (A) where either AHP or Millennium is the Responsible Party, ************************** to the Responsible Party and ************************* to the other Party, provided, however, that if the Responsible Party does not institute suit or take action as set forth in Section 6.7(b) or elects not to respond to an invalidity claim pursuant to Section 6.9, then the recovery shall be paid ************* ***** to each Party, or (B) where AHP and Millennium are the Responsible Party jointly (i.e. in the case of Joint Program Patent Rights), ******************* to each Party. - 49 - 56 Section 6.8. Notice of Certification. Millennium and AHP each shall immediately give notice to the other of any certification filed under the U.S. "Drug Price Competition and Patent Term Restoration Act of 1984", or comparable law in other countries where applicable Program Patent Rights covering a product sold by Millennium or AHP are maintained, claiming that such Program Patent Right is invalid or that any infringement will not arise from the manufacture, use or sale of any product in the Core Field by a third party. If the Responsible Party decides not to bring infringement proceedings against a third party making such a certification, the Responsible Party shall give notice to the other Party of its decision not to bring suit as soon as practicable but no later than twenty-one (21) days after receipt of notice of such certification. The other Party may then, but is not required to, bring suit against the party that filed the certification. Any suit by AHP or Millennium shall either be in the name of AHP or in the name of Millennium, or jointly by AHP and Millennium, as may be required by law. For this purpose, the Party not bringing suit shall execute such legal papers necessary for the prosecution of such suit as may be reasonably requested by the Party bringing suit. Section 6.9. Claimed Infringement; Claimed Invalidity. (a) If the activities of either Party in connection with the Research Program, the AHP Discovery Program or as the result of making, importing, using, offering to sell or selling a Product in the CNS Disorders Field result in a claim of patent infringement or other violation of the intellectual property rights of any third party, the Party who is accused of such infringement shall defend itself at its sole cost. The other Party shall cooperate with the accused Party in such defense and prosecution and shall have the right to be represented by counsel of its own choice. (b) If a third party at any time asserts a claim that any Program Patent Right is invalid or otherwise unenforceable (an "Invalidity Claim"), whether as a defense in an infringement action brought by AHP or Millennium pursuant to Section 6.7 or Section 6.8, or in an action brought against AHP or Millennium, the Parties shall cooperate with each other in preparing and formulating a response to such Invalidity Claim. The Party responsible for responding to such claim, at its sole expense, shall be initially the Responsible Party, subject to the other Party's right, at its sole expense, to assume responsibility if the Responsible Party elects not to do so. Neither Party shall settle or compromise any Invalidity Claim without the consent of - 50 - 57 CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION. ASTERISKS DENOTE SUCH OMISSIONS. the other Party, which consent shall not be unreasonably withheld, provided that no such consent of Millennium shall be required with respect to an Invalidity Claim relating to Patent Rights owned by, licensed to or otherwise controlled by AHP (other than Millennium Program Patent Rights). Article VII AHP Due Diligence Section 7.1. Research Program Inventory. As set forth in this Article VII, AHP is required to exercise commercially reasonable efforts to develop Products based upon the results of the Research Program. For purposes of assessing the adequacy of the efforts devoted by AHP thereto (and not for purposes of determining whether a Product is a Royalty-bearing Product), the CNS JMT shall, within ninety (90) days after the end of each Contract Year during the term of the Research Program and each twelve (12) month period thereafter for a period of three (3) years, provide a written inventory to each Party listing the following: (a) each Candidate Gene; (b) each Validated Target; (c) each Validated Vaccine Candidate (based upon the advice of the Vaccine Management Team); (d) each disease indication relevant to a Candidate Gene, Validated Target or Validated Vaccine Candidate (each such indication, which must have at least one relevant Validated Target or Validated Vaccine Candidate in such inventory, referred to as a "Disease Indication"); and (e) in the Final Inventory (as defined below), all Designated Candidate Genes (as that term is defined in Section 5.6) (each such inventory referred to as a "Program Inventory" and the Program Inventory for the last Contract Year during the term of the Research Program, as modified as described below, referred to as the "Final Inventory"). The Final Inventory shall be modified to include Disease Indications which relate to Validated Targets or Validated Vaccine Candidates which achieve such status during the ********************* ************************* of the Research Program. Section 7.2. Candidate Genes. (a) AHP shall use commercially reasonable efforts to move Candidate Genes into Validated Target or Validated Vaccine Candidate status within *************************************** of the Research Program. Such efforts shall not be less than the efforts expended by AHP in connection with its other research and development projects that are at a comparable stage of the - 51 - 58 CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION. ASTERISKS DENOTE SUCH OMISSIONS. research and development process and that are of comparable scientific and commercial promise. (b) AHP shall provide Millennium with a written report describing AHP's progress in moving Candidate Genes into Validated Target or Validated Vaccine Candidate status, provided that no such report shall be required until after the first Candidate Gene is identified. Such reports shall be provided (i) within thirty (30) days after each June 30 and December 31 during the two (2) year period following the termination of the Research Program, (ii) within thirty (30) days after each June 30 during the three (3) following years, and (iii) thereafter if and when AHP has progress to report relating to moving Candidate Genes into Validated Target or Validated Vaccine Candidate status. (c) AHP shall be deemed to have satisfied its obligations under subsection (a) in the event that it is using the commercially reasonable efforts required pursuant to subsection (a) at any given time to develop at least *************** (rounded to the nearest whole number) of the ************************ (as defined below) into *****************. As used herein, the term ************************** means a number of ***** equal to the sum of Candidate Genes and *************** of all Designated Candidate Genes, if any, included in the Final Inventory. Disputes regarding fulfillment of AHP's obligations under this Section 7.2 shall be resolved in accordance with Section 7.5. (d) If AHP fails to exercise commercially reasonable efforts as required under this Section 7.2 then, at the election of Millennium, the exclusive rights of AHP with respect to those Candidate Genes (including Designated Candidate Genes) (i) as to which AHP has not initiated and conducted continuing research efforts to develop a Validated Target or Validated Vaccine Candidate, and (ii) which do not relate to any Disease Indication included in the most recent Program Inventory for which AHP is conducting active and continuing research efforts under the AHP Research Program or AHP Discovery Program, shall be converted to co-exclusive rights (with Millennium, either alone or in collaboration with others). The foregoing shall be Millennium's sole and exclusive remedy for the failure by AHP to use the commercially reasonable efforts required under this Section 7.2. - 52 - 59 CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION. ASTERISKS DENOTE SUCH OMISSIONS. Section 7.3. Disease Indications. (a) AHP shall use commercially reasonable efforts to develop a Product for each Disease Indication included in each Program Inventory, including the Final Inventory (as modified pursuant to Section 7.1). Such efforts shall not be less than the efforts expended by AHP in connection with its other research and development projects that are at a comparable stage of the research and development process and that are of comparable scientific and commercial promise. AHP's obligations under this subsection (a) shall apply during the period (the "Section 7.3 Due Diligence Period") commencing with the date of the initial Program Inventory and continuing until ******************* the date of the Final Inventory (including the final modification thereto as of the ************************************ of the Research Program). (b) AHP shall provide Millennium with a written report describing AHP's progress in developing Products for Disease Indications included in the most recent Program Inventory. Such reports shall be provided (i) within thirty (30) days after each June 30 during the ********************************************* of the Research Program, and (ii) thereafter if and when AHP has progress to report relating to developing Products for Disease Indications included in the Final Inventory. (c) AHP shall be deemed to have satisfied its obligations under subsection (a) in the event that it is using the commercially reasonable efforts at all times during the Section 7.3 Due Diligence Period (which shall include, at a minimum, active efforts to screen against relevant Validated Targets and/or to use relevant Validated Targets as the basis for structure-based rational drug design) required pursuant to subsection (a) at any given time to develop a Product for **************** (rounded to the nearest whole number) of the ******************* included in the most recent Program Inventory. (d) If AHP fails to exercise commercially reasonable efforts as required under this Section 7.3, then, at the election of Millennium, the exclusive rights of AHP with respect to those Validated Targets or Validated Vaccine Candidates (together with all related Candidate Genes) (i) as to which AHP has not initiated and conducted continuing screening and related efforts to discover and develop a Product, and - 53 - 60 CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION. ASTERISKS DENOTE SUCH OMISSIONS. (ii) which do not relate to any Disease Indication included in the most recent Program Inventory for which AHP is conducting active and continuing research and development efforts under the AHP Research Program or AHP Discovery Program, shall be converted to co-exclusive rights (with Millennium, either alone or in collaboration with others). The foregoing shall be Millennium's ************************* for the failure by AHP to use the commercially reasonable efforts required under this Section 7.3. (e) Notwithstanding the provisions of this Section 7.3, at any time prior to the date of the Final Inventory (including the final modification thereto as of **************************** *********** of the Research Program), AHP shall have the right, by providing written notice to Millennium, to delete a specified ****************** from the Program Inventory. Any such deletion shall have the following effects: (i) such ****************** shall no longer be considered to be part of the Program Inventory for assessing whether AHP has satisfied its obligations under subsections (a) or (c) above; (ii) such ****************** shall cease to be in the *******************; and (iii) all licenses granted by Millennium to AHP with respect to Validated Targets and Validated Vaccine Candidates (together with all related Candidate Genes) that relate solely to such ****************** shall terminate effective as of the date of AHP's notice. Section 7.4 Commercialization. (a) AHP agrees to use commercially reasonable efforts to conduct required clinical development activities and seek regulatory approval in Major Market Countries for each Small Molecule Product and Vaccine Product. Such efforts shall not be less than the efforts expended by AHP in connection with its other development projects that are at a comparable stage in the development process and are of comparable commercial promise. Upon receipt of regulatory approval, AHP agrees to use commercially reasonable efforts to market and sell each such Small Molecule Product and Vaccine Product in Major Market Countries. (b) Within thirty (30) days after the end of each calendar quarter, AHP shall provide Millennium with a written report describing AHP's efforts with respect to the development and/or commercialization of each Small Molecule Product and Vaccine Product in each Major Market Country. - 54 - 61 (c) AHP shall be deemed to have satisfied its obligations under subsection (a) with respect to a Small Molecule Product or Vaccine Product in the event that it is using the commercially reasonable efforts required pursuant to subsection (a) at any given time in at least three (3) Major Market Countries with respect to each such Product. (d) If AHP shall fail to exercise commercially reasonable efforts as required under this Section 7.4 with respect to any Small Molecule Product or Vaccine Product, Millennium shall notify AHP. Effective ninety (90) days thereafter, if AHP has not cured such failure, then AHP's exclusive rights with respect to the development and commercialization of such Small Molecule Product or Vaccine Product, as the case may be, in each Major Market Country in which AHP has failed to exercise such commercially reasonable efforts (an "Abandoned Market") shall terminate, and AHP shall grant to Millennium a fully paid-up non-royalty bearing license to develop and commercialize, either alone or in collaboration with third parties, such Small Molecule Product or Vaccine Product, as the case may be, in each Abandoned Market. In such instance, AHP shall (i) transfer to Millennium any and all regulatory and clinical information related to such Small Molecule Product or Vaccine Product, as the case may be, that AHP owns or otherwise controls and as to which AHP has the right to grant licenses or sublicenses without violating the terms of any agreement or other arrangement with a third party (the "Product Related Information"), and (ii) grant to Millennium a fully paid-up non-royalty bearing license to use such Product Related Information to develop and commercialize such Small Molecule Product or Vaccine Product, as the case may be, in each Abandoned Market. AHP's rights hereunder with respect to such Small Molecule Product or Vaccine Product, as the case may be, in other Major Market Countries, or to other Products in the Abandoned Market, shall be unaffected. The foregoing shall be Millennium's sole and exclusive remedy for the failure by AHP to use the commercially reasonable efforts required under this Section 7.4 (e) Notwithstanding the foregoing, AHP shall not be obligated to use commercially reasonable efforts to conduct clinical development activities, seek regulatory approval and market and sell any Small Molecule Product or Vaccine Product with respect to which a Product Patent Blocking Event has occurred. In the event that a Party makes a determination that a Product Patent Blocking Event has occurred, such Party shall notify the other Party, and shall provide with such notice support for its determination. In the event that the other Party disagrees with - 55 - 62 CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION. ASTERISKS DENOTE SUCH OMISSIONS. such determination, the matter shall be referred to the Executive Officers for resolution pursuant to Section 2.3(b)(iv), with the advice of mutually acceptable outside patent counsel not regularly employed by either Party. Section 7.5. Determination of Due Diligence. In the event that Millennium does not believe that AHP has satisfied its obligations under Sections 7.2(a), 7.3(a) or 7.4(a), Millennium shall notify AHP in writing. If AHP believes that it has satisfied such obligations, it shall so notify Millennium within ten (10) Business Days after receipt of Millennium's notice. Such notice by AHP shall indicate whether AHP believes it has met the "safe harbors" set forth in Sections 7.2(c), 7.3(c) or 7.4(c), as applicable (the "Safe Harbor Provisions"), or whether AHP believes it has otherwise satisfied its obligations under Sections 7.2(a), 7.3(a) or 7.4(a), as applicable, and, in either event, provide supporting information for such position. If Millennium disagrees with AHP's response, either because it does not believe that the applicable Safe Harbor Provision has been satisfied or, if AHP has indicated that it has not met the applicable Safe Harbor Provision, because it does not believe that AHP has otherwise satisfied its obligations, the Parties shall attempt in good faith to resolve the disagreement, referring the matters to the Executive Officers for resolution pursuant to Section 2.3(b), if necessary. In the event that (a) the Parties are unable to resolve any disagreement under this Section 7.5, and (b) AHP has not met the applicable Safe Harbor Provision, then AHP shall bear the burden of proof relating to its satisfaction of its obligations under Sections 7.2(a), 7.3(a) or 7.4(a), as applicable.

Notice of Millennium's election to have AHP purchase Common Stock (an "Equity Election Notice") shall be provided by Millennium to AHP at least sixty (60) days prior to the end of the third or fifth Contract Year, as applicable. The Purchase Date shall mean (i) in the case of a purchase relating to the achievement of the Year Three Extension Benchmark, the date one (1) Business Day after the end of the third Contract Year, and (ii) in the case of a purchase relating to the achievement of the Year Five Extension Benchmark, the date one (1) Business Day after the end of the fifth Contract Year. The "Fair Market Value" shall be equal to the average closing price of the Common Stock on the NASDAQ National Market (or other principal securities exchange on which the Common Stock is then traded) during the ten (10) Business Days ending on the Business Day preceding the third Business Day prior to the end of the third or fifth Contract Year, as applicable (the "Measurement Period"). Notwithstanding the foregoing, in the event that (A) the Fair Market Value is fifteen percent (15%) or more lower than the average closing price of the Common Stock on the Nasdaq National Market (or other principal securities exchange on which the Common Stock is then traded) during the ten (10) Business Days ending sixty (60) days prior to the end of the third or fifth Contract Year, as applicable (such average price being referred to as the "Prior Fair Market Value"), Millennium shall have the right to cancel the closing by providing notice to AHP during the three (3) Business Day period prior to the end of the third or fifth Contract Year, as applicable. Furthermore, in the event that the Fair Market Value exceeds the Prior Fair Market Value by fifteen (15%) or more, then the purchase price shall be equal to one ****************************************************************** *************, provided that Millennium shall have the right to cancel the closing by providing notice to AHP during the three (3) Business Day period prior to the end of the third or fifth Contract Year, as applicable. In the event that Millennium exercises its rights to cancel a closing, Millennium shall have no further right to receive the cancelled equity investment (but any cancellation of the equity payment relating to the third Contract Year shall have no effect on the equity payment, if any, relating to the fifth Contract Year). Each purchase of Common Stock under this Section 8.2 shall be pursuant to, and shall be subject to the conditions in, an agreement which shall include the terms set forth on Appendix D to this Agreement. Notwithstanding the provisions of this Section 8.2 to the contrary, in the event that, on any Purchase Date, the Common Stock of Millennium (or any - 58 - 65 CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.
