Also, within [**] days following the receipt of each invoice from Harvard, Licensee shall reimburse Harvard for amounts paid by Harvard to its patent counsel with respect to review of Licensee’s preparation, filing, protection, prosecution and maintenance of Licensee Prosecuted Patent Rights in which Harvard has an ownership interest. In addition, within [**] days following the receipt of an invoice from Harvard and/or DFCI, Licensee shall reimburse Harvard and DFCI, as appropriate, for expenses incurred by Licensors prior to the Effective Date, and in connection with the transfer of responsibility to Licensee as described in Section 3.1.2, with respect to the preparation, filing, prosecution and/or maintenance of the Licensors Patent Rights, [**] Poly Peptide Patent Rights, [**] Patent Rights, [**] Patent Rights and p53 Patent Rights.

3.3. Abandonment. Should Licensee decide that it does not wish to pay for the filing or prosecution of a patent application, or the maintenance of a patent, on any invention or claim included in the Licensed Patent Rights, in any country (an “Abandoned Country”), Licensee shall provide Harvard and/or DFCI, as applicable based on ownership, with written notice of such election at least [**] days prior to the effective date of such abandonment (and in no event less than [**] days prior to the date on which any pending action needs to be taken to preserve the relevant Licensed Patent Rights). Upon the effective date of such abandonment, Licensee shall be released from its obligation to pay for the prosecution of, or to reimburse Harvard for the expenses incurred by Harvard thereafter in conjunction with, such Licensed Patent Rights in such Abandoned Country; provided that expenses for work or filing fees authorized prior to the receipt by Harvard and/or DFCI of such notice shall be deemed incurred prior to the notice.

3.3.1. Effect of Abandonment of Harvard Patent Rights, [**] Poly Peptide Patent Rights, [**] Patent Rights, [**] Patent Rights, P53 Patent Rights, Licensors Patent Rights and/or DFCI Patent Rights. In the event of Licensee’s abandonment of any Harvard Patent Rights, [**] Poly Peptide Patent Rights, [**] Patent Rights, [**] Patent Rights, P53 Patent Rights, Licensors Patent Rights and/or DFCI Patent Rights, any license granted by Harvard and/or DFCI to Licensee hereunder with respect to such Licensed Patent Rights will terminate in the relevant Abandoned Country, and Licensee will have no rights whatsoever to exploit such abandoned Licensed Patent Rights in such Abandoned Country. Harvard and/or DFCI shall then be free, without further notice or obligation to Licensee, to grant rights in and to such abandoned Licensed Patent Rights in such Abandoned Country to third parties.

3.3.2. Effect of Abandonment of Joint Patent Rights. In the event of Licensee’s abandonment of any Joint Patent Rights, Harvard (and/or DFCI, if DFCI is the joint owner of such Patent Rights with Licensee) may assume responsibility for paying for the preparation, filing, prosecution, protection and/or maintenance of such Joint Patent Rights in such Abandoned Country, in its sole discretion. In such event, such paying Licensor(s) may choose, at its sole discretion, to terminate any license granted by such Licensor to Licensee hereunder with respect to such Joint Patent Rights in such Abandoned Country. If such Licensor exercises its right to terminate: (a) the license granted hereunder with respect to such Joint Patent Rights in such Abandoned Country shall terminate and (b) such Licensor(s) thereafter shall be free, without further notice or obligation to Licensee, and Licensee hereby grants such Licensor(s) an exclusive license (subject to the provisions of this Section 3.3.2) under its interest in such Joint Patent Rights in such Abandoned Country, to grant rights in and to such Joint Patent Rights in such Abandoned Country to third parties; provided, however, that such third party licenses shall be subject to Licensee retaining the right, without further notice or obligation to Harvard, to practice and otherwise exploit its interest in such Joint Patent Rights in such Abandoned Country in connection with any development or commercialization of a Licensed Product by or on behalf of Licensee or its Affiliates, and to grant rights to third parties in and to its interest in such Joint Patent Rights in such Abandoned Country in connection with a license of a Licensed Product developed by or on behalf of Licensee, its Affiliates or any Sublicensee. The claims of any Joint Patent Rights to which Licensee’s license is terminated in an Abandoned Country pursuant to this Section 3.3.2 shall cease to constitute Valid Claims for purposes of this Agreement.

3.4. No Warranty. Nothing contained herein shall be deemed to be a warranty by Licensors that they can or will be able to obtain patents on patent applications included in the Licensed Patent Rights, or that any of the Licensed Patent Rights will afford adequate or commercially worthwhile protection.

3.5. Small Entity Designation. If Licensee, any Sublicensee and/or any holder of an option to obtain a Sublicense does not qualify, or at any point during the term of this Agreement ceases to qualify, as a “small entity” as provided by the United States Patent and Trademark Office (USPTO), Licensee immediately shall so notify the USPTO (with respect to Licensed Patent Rights for which Licensee has prosecution responsibility under the terms of this Agreement), as well as Licensors in order to enable Licensors to comply with USPTO regulations regarding payment of fees with respect to Licensed Patent Rights.

- 13 -

4.1.4.4. Third Party Proposed Products.

(a) If, at any time after August 2, 2011, a third party makes a bona fide proposal to either Licensor for developing a Third Party Proposed Product and Harvard is interested in having such Third Party Proposed Product developed and commercialized, Harvard shall notify Licensee of such Third Party Proposed Product, and shall provide Licensee with information regarding the third party proposal. Within [**] days of the receipt of such notification from Harvard, [**].

(b) If Licensee notifies Harvard within such [**] day period that [**], the parties will agree upon [**] with respect to such Third Party Proposed Product, which [**], subject to necessary adjustments, and will include reasonable [**]. In such case, Licensee shall be obligated (i) to use commercially reasonable efforts to [**] in accordance with such new [**] and (ii) to [**] with respect to the Third Party Proposed Product.

(c) If Licensee notifies Harvard that [**] (consistent with the considerations set forth in the following sentence) [**] with such third party or another party. Bona fide business concerns of Licensee as well as the goal of ensuring that Licensed Products are developed and commercialized to benefit the public will be considered by Licensee in its determination of [**]. Licensee shall have no obligation to license or sublicense any other intellectual property (i.e. [**]) to a prospective sublicensee. If Licensee has not entered into a [**] within a reasonable time after its notice to Harvard, at Harvard’s request, it shall notify Harvard (in person or by telephone) the [**] shall be deemed Confidential Information of Licensee in accordance with Section 12.6.

(d) If Licensee does not notify Harvard within the [**] day period described in (a) above or notifies Harvard [**] to (A) [**] or to (B) enter into [**] with such third party or another party for such product, Harvard shall be [**] to such third party and otherwise consistent with the rights granted to Licensee herein. From all amounts received by Harvard under [**], (i) Harvard shall first deduct [**] and (ii) all remaining amounts shall be distributed as follows: [**]. Harvard shall notify Licensee when it commences negotiations with such third party, and shall provide a copy of any such license to Licensee, the terms of which shall be deemed Confidential Information of Harvard in accordance with Section 12.6.

4.1.5. Affiliates and Sub-contractors. The licenses granted to Licensee under Sections 4.1.1, 4.1.2 and 4.1.3 shall include the right to have some or all of Licensee’s rights or obligations under such licenses performed or exercised by one or more of its Affiliates and/or through Sub-contractors; provided that: (a) no such Affiliate or Sub-contractor shall be entitled to grant, directly or indirectly, to any person or entity any Sublicense; and (b) any acts taken by any such Affiliate or Sub-contractor (or assignee thereof as described in the next sentence) in accordance with the rights granted under this Section 4.1.5 shall be deemed an act taken by Licensee under this Agreement. For clarity, the assignment of such rights by an Affiliate or Subcontractor in connection with the sale of its business or assets to which such rights pertain or otherwise to a successor-in-interest as a result of a merger or reorganization or otherwise shall not be deemed to be a Sublicense prohibited by this Section 4.1.5.

- 14 -

4.2. Sublicense.

4.2.1. Sublicense Grant. Licensee shall be entitled to grant Sublicenses to third parties under the licenses granted pursuant to Section 4.1 on terms and conditions in compliance with and not inconsistent with the terms of this Agreement.

4.2.2. Sublicense Agreements. Sublicenses shall only be granted pursuant to written agreements, which shall be subject and subordinate to the terms and conditions of this Agreement. Such Sublicense agreements shall contain, among other things, provisions to the following effect;

4.2.2.1. All provisions necessary to ensure Licensee’s ability to perform its obligations under this Agreement, including without limitation its obligations under Sections 7.1, 7.3 and 12.1;

4.2.2.2. A clause substantially the same as the provisions of Section 10 (Indemnification) that shall also state that Harvard, DFCI and HHMI are intended third party beneficiaries of such Sublicense agreement for the purpose of enforcing such indemnification and insurance provisions.

4.2.2.3. Upon any termination of this Agreement, all Sublicenses shall terminate. However, in recognition of the substantial investment made by Sublicensees in commercializing the Licensed Patent Rights, and to avoid future negotiation over the terms of a Sublicensee’s continued exercise of the Licensed Patent Rights in the field and scope enjoyed pursuant to its Sublicense Agreement, Licensors will, at the request of a Sublicensee after such termination, grant a direct license under the Licensed Patent Rights to such Sublicensee (effective as of the date of the termination of this Agreement) for the Licensed Products and the field specified in its Sublicense Agreement and under the same terms and conditions (except as set forth in (c) and (d) below) as those granted to Licensee under this Agreement, provided that:

(a) such Sublicensee is not in material default under the Sublicense Agreement at the time of termination of this Agreement;

(b) such Sublicensee assumes all unsatisfied past, current, and future obligations of Licensee under this Agreement, including under Section 3.2 and 6, with respect to the Licensed Products and field covered by its Sublicense;

(c) such Sublicensee agrees: (i) with respect to Original Patent Rights covered by such Sublicense, to use commercially reasonable efforts, and/or cause its Affiliates to use commercially reasonable efforts (x) to develop Licensed Products, the making, using or selling of which is covered by a Valid Claim of the Original Patent Rights, (y) to introduce such Licensed Products into the commercial market and (z) to market such Licensed Products following such introduction into the market (including undertaking in such direct license to meet all applicable diligence milestones as set forth in the Sublicense agreement), in which event Sublicensee shall not be obligated to meet the original General Development Milestone within the time period set forth in this Agreement; and (ii) with respect to all of the other Licensed Patent Rights covered by such Sublicense, to meet the relevant Development Milestones (e.g. [**] Development Milestone, [**] Development Milestone, [**] Development Milestone, p53 Development Milestone and/or [**] Poly Peptide Milestone) within the time periods set forth in this Agreement, in which event such Sublicensee shall be obligated to meet such Development Milestones with such time periods; and

- 15 -

(d) (i) the terms contained in such direct license agreement do not impose any representation, warranties, obligations or liabilities on Licensors or the Sublicensee which are not included in this Agreement and includes limitations of liability provisions identical to those set forth in Sections 9.2 and 9.3, (ii) Sublicensee assumes all of Licensee’s obligations under Sections 5.3, 7.1.1, 7.3, 9.1, 10, 12.1, 12.4 and 12.7 with respect to the Licensed Products or field covered by its Sublicense, (iii) the royalty rates and milestone payments contained in such new agreement shall be equivalent to the royalty rates and milestone payments specified in Sections 6.4 and 6.5 of this Agreement), (iv) Licensors shall not be entitled to any stock or equity payment or issuance from the Sublicensee on account of such direct license, (v) the obligations to reimburse of patent prosecution expenses and pay license maintenance fees contained in the direct license agreement shall not be less favorable to Licensors than those set forth in Sections 3 and 6.3 of this Agreement, respectively; provided, however, that such prosecution expenses and license maintenance fees shall be prorated among all former Sublicensees to whom Licensors grant a direct license under this Section 4.2.2.3 and whose such direct licenses are in effect on the date payments are due.

4.2.2.4. The Sublicensee shall not be entitled to sublicense its rights under such Sublicense agreement. However, Sublicensee shall be entitled to have some or all of its rights or obligations under such Sublicense performed or exercised by one or more of its Affiliates and/or through Sub-contractors; provided that any acts taken by any such Affiliate or Sub-contractor (or assignee thereof as described in the next sentence) in accordance with the rights granted under this Section 4.2.2.4 shall be deemed an act taken by Sublicensee under the Sublicense agreement. For clarity, the assignment of a Sublicense agreement by a Sublicensee in connection with the sale of its business or assets to which the Sublicense agreement pertains or otherwise to a successor-in-interest as a result of a merger or reorganization or otherwise shall not be deemed to be a Sublicense prohibited by this Section 4.2.2.4.

4.2.2.5. The Sublicense agreement may not be assigned by Sublicensee without the prior written consent of Harvard, except that Sublicensee may assign the Sublicense agreement without the consent of Harvard (i) to an Affiliate of such Sublicenses or (ii) to a successor-in-interest in connection with the merger, consolidation, or sale of all or substantially all of its assets or that portion of its business or assets to which the Sublicense agreement relates; provided that any such assignee agrees in writing in a manner reasonably satisfactory to Harvard to be bound by the terms of such Sublicense agreement.

4.2.3. Delivery of Sublicense Agreement. Licensee shall furnish Licensors with a fully executed copy of any such Sublicense agreement promptly after its execution. Licensors shall keep any such copies of Sublicense agreements in its confidential files and shall use them solely for the purpose of monitoring Licensee’s and Sublicensees’ compliance with their obligations hereunder and enforcing Licensors’ rights under this Agreement. Any such Sublicense agreement shall be deemed Confidential Information of Licensee in accordance with Section 12.6.

4.2.4. Breach by Sublicensee. Any act or omission by a Sublicensee, which would have constituted a breach of this Agreement had it been an act or omission by Licensee,

- 16 -

shall constitute a breach of this Agreement. Licensee shall indemnify Licensors and HHMI for, and hold them harmless from, any and all damages or losses caused to Licensors and HHMI as a result of any such breach by a Sublicensee. For clarity, Licensee shall have the right to cure any such breach in the same manner as it has the right to cure its own breaches.

4.3. No Other Grant of Rights. Nothing in this Agreement shall be construed to confer any rights upon Licensee by implication, estoppel, or otherwise as to any technology or patent rights of Licensors or any other entity other than the rights granted herein with respect to Licensed Patent Rights, regardless of whether such technology or patent rights shall be dominant, subordinate or otherwise related to any Licensed Patent Rights.

5.	Development and Commercialization.

5.1. Diligence. Licensee shall use commercially reasonable efforts, and/or shall cause its Affiliates or Sublicensees to use commercially reasonable efforts: (i) to develop Licensed Products in accordance with the Development Plan, (ii) to introduce Licensed Products into the commercial market and (iii) to market Licensed Products following such introduction into the market. In addition, Licensee, by itself or through Affiliates or Sublicensees, shall meet each of the Development Milestones within the time periods set forth therein. Without limiting Licensors’ rights under any other provision of this Agreement, Licensors’ sole and exclusive remedy and Licensee’s sole and exclusive liability for any breach of the obligations set forth in this Section 5.1 shall be the termination rights set forth in Section 5.5. For clarity, it is contemplated that Licensee, its Affiliate or Sublicensee can achieve the General Development Milestone simultaneously upon achieving a milestone described in any of Sections 1.7 (b)-(f) with the same Licensed Product. For further clarity, if a Licensed Product is covered by a Valid Claim of two or more categories of Licensed Patent Rights, it is possible that it can meet the Development Milestone in each such category if applicable. For example, if a Licensed Product is covered by Valid Claims within both the [**] Patent Rights and the [**] Poly Peptide Patent Rights, and Licensee files an IND for such Licensed Product within the time periods required for the IND [**] Development Milestone and the IND [**] Development Milestone, then both such Development Milestones will be deemed to have been met by such IND filing.

5.2. Development Plan. Licensee shall be entitled, from time to time, to make such adjustments to the then applicable Development Plan including the timelines therein as Licensee believes, in its good faith judgment, are needed in order to improve Licensee’s ability to meet the Development Milestones.

5.3. Reporting. Within [**] days after the end of each calendar year, Licensee shall furnish Harvard with a written report on the progress of its, its Affiliate’s and Sublicensees’ efforts during the prior year to develop and commercialize Licensed Products, including without limitation research and development efforts and marketing efforts. The report shall also contain a discussion of intended efforts and sales projections for the then current year.

5.4. Failure. The parties agree that timely achievement of Development Milestones is subject to considerable uncertainty, given the novelty of the technology embodied in the Licensed Patent Rights, territorial or legal restrictions on the use of biotechnology products, the regulatory climate and approval process, and pricing or other government restrictions on certain

- 17 -

pharmaceutical products. Accordingly if Licensee fails to achieve any Development Milestone, the parties agree to discuss and, if appropriate, revise said milestone upon Licensee’s written notice to Harvard and explanation for the reasons for such failure. If Licensee does not provide Harvard with a reasonable basis for its failure to meet a Development Milestone (and lack of finances shall not constitute reasonable basis), Harvard shall notify Licensee in writing of Licensee’s failure and shall allow Licensee [**] days to cure its failure; provided that Harvard agrees to consider in good faith a reasonable extension to such [**]-day period if such failure occurs despite Licensee’s (itself or through one or more Affiliates or Sublicensees) use of commercially reasonable efforts to meet such Development Milestone.

5.5. Remedy for Failure.

5.5.1. General Development Milestone. If a failure to meet a Development Milestone as described in Section 5.4 relates to the General Development Milestone, Licensee’s failure to cure such delay within such [**]-day period (as may be extended) set forth in Section 5.4 shall constitute a material breach of this Agreement and Harvard shall have the right to terminate this Agreement forthwith.

5.5.2. Other Development Milestones. If a failure to meet a Development Milestone as described in Section 5.4 relates to a Development Milestone that is not the General Development Milestone (i.e., [**] Development Milestone, [**] Development Milestone, [**] Development Milestone, p53 Development Milestone or [**] Poly Peptide Milestone), Licensee’s failure to cure such delay within such [**]-day period set forth in Section 5.4 shall entitle Harvard (or in the case of a failure to achieve a [**] Development Milestone, DFCI) to terminate Licensee’s license with respect to the Licensed Patent Rights solely related to such Development Milestone (“Terminated Patent Rights”). For example, if the failure to meet a Development Milestone as described in Section 5.4.2 relates to a [**] Development Milestone, Harvard will be entitled to terminate the license granted under Section 4.1.2 with respect to the [**] Patent Rights. For clarity, the termination of the license with respect to any Terminated Patent Rights under this Section 5.5.2 will terminate any Sublicense granted with respect to such Terminated Patent Rights (and Licensors will not be required to grant any licenses with respect to such Terminated Patent Rights to any Sublicensee). For further clarity, Licensee’s rights and obligations under Sections 3 and 8 with respect to any Terminated Patent Rights shall terminate.

5.5.3. Background for Terminated Patent Rights. Notwithstanding the terms of Section 4.1.1, if any Licensed Patent Rights become Terminated Patent Rights, Harvard will be entitled to grant to third party licensees of such Terminated Patent Rights non-exclusive, worldwide, licenses (with the right to grant sublicenses) under the Harvard Patent Rights and [**] Poly Peptide Patent Rights in the Field solely for the purpose of and to the extent needed to develop, make, have made, use, market, offer for sale, sell and import products, the making, using or selling of which falls within the scope of a Valid Claim of such Terminated Patent Rights.

In partial consideration for the license granted to Licensee pursuant to Section 4.1.2 above with respect to the p53 Patent Rights, Licensee shall pay Harvard a license issuance fee of [**] US Dollars ($[**]). Such amount will be paid in three installments, as follows: (a) [**] US Dollars ($[**]) will be paid within [**] business days after the Effective Date; (b) [**] US Dollars ($[**]) will be paid within [**] business days after the [**] of the Effective Date; and (c) [**] US Dollars ($[**]) will be paid within [**] business days after the [**] of the Effective Date.

6.1.2.4. [**] Patent Rights. In partial consideration for the license granted to Licensee pursuant to Section 4.1.3 above with respect to the [**] Patent Rights, Licensee shall pay Harvard a license issuance fee of [**] US Dollars ($[**]).

For clarity, Licensee shall be obligated to pay the full amount of each installment set forth in this Section 6.1.2 on the due date therefore regardless of whether, at the time the relevant installment is due, (i) this Agreement is still in effect or (ii) the relevant Licensed Patent Rights are still licensed under this Agreement (or have become Terminated Patent Rights).

Each milestone payment shall be payable only upon the initial achievement of such milestone with respect to a Therapeutic Product and no amounts shall be due hereunder for subsequent or repeated achievement of such milestone with respect to such Therapeutic Product. For clarity, the milestones set forth in Section 6.4.1 are successive and, upon achievement of any milestone by a Therapeutic Product, all prior milestones for such Therapeutic Product shall be deemed achieved and, to the extent any payments were not made with respect thereto, the corresponding payments shall be due. For purposes of the milestone payments in this Section 6.4.1 all Licensed Products incorporating the same Covered Peptide shall be deemed to be the same Therapeutic Product.

If development of a Therapeutic Product is abandoned after one or more of the milestone payments set forth in Sections [**] have been made with respect to such Therapeutic Product (“Abandoned Therapeutic Product”), but before the [**] of such Abandoned Therapeutic Product, then such milestone payments shall be credited against any milestone payments that subsequently become due pursuant to Sections [**] for any other Therapeutic Product that is intended to prevent or treat the same indication, is directed to the same biological target(s) and has substantially the same mechanism of action as the Abandoned Licensed Product (a “Back-Up Product”), until such amounts have been fully credited. The above notwithstanding, if Licensee thereafter revives development efforts with respect to such Abandoned Therapeutic Product and such efforts lead to the attainment of the milestone described in Section [**], as applicable, that follows the last milestone for which payment was made prior to abandonment, Licensee shall be required to reimburse Harvard the full amount credited pursuant to this paragraph upon reaching such milestone. For purposes of illustration, [**].

6.4.2. Diagnostic Products. In addition, Licensee shall pay Harvard the following milestone payments with respect to each Licensed Product being commercialized for the diagnosis of [**] (a “Diagnostic Product”) to reach the relevant milestone, regardless of whether such milestone is achieved by Licensee or a Sublicensee:

6.4.2.1. $[**] US Dollars) upon the earlier of [**]; and

6.4.2.2. $[**] US Dollars) upon the achievement of cumulative worldwide sales of the first Diagnostic Product of $[**] US Dollars).

Licensee shall notify Harvard in writing within [**] days following the achievement of each milestone described in this Section 6.4.2, and shall make the appropriate milestone payment within [**] days after the achievement of such milestone.

6.5. Royalties on Net Sales.

6.5.1. Licensee shall pay Harvard royalties on Net Sales as follows:

(a)

An amount equal to [**]% of all Net Sales of [**] Products; and

(b)

An amount equal to [**]% of all Net Sales of [**] Products; and

(c)

An amount equal to [**]% of all Net Sales of Combination Products (with Net Sales as determined in Section 1.25) in which the Covered Peptide would be considered a [**] product if sold with no Independent Active Ingredient; and

(d)

6.5.2. Notwithstanding the foregoing, in the event that Licensee or an Affiliate of Licensee is required to make royalty payments, at fair market terms after arms’ length negotiations, under a Third Party License as a result of the sale of a Licensed Product in a certain country, Licensee may offset an amount equal to [**]% of such third-party payments with respect to such sale of such Licensed Product against the royalty payments that are due to Licensors pursuant to Section 6.5.1 with respect to sales of such Licensed Product in such country; provided that in no event, shall the royalty payments to Licensors under Section 6.5.1 with respect to such Licensed Product be reduced by more than [**]% of the amount otherwise due with respect to such Licensed Product.

- 23 -

6.5.3. With respect to each Licensed Product, royalties will be payable on a country-by-country basis, so long as the making, using or selling of the Licensed Product falls within the scope of a Valid Claim in the country in which such Licensed Product is made, used or sold.

6.5.4. If the use, manufacture, sale or importation of any Licensed Product is covered by more than one Valid Claim of the Licensed Patent Rights, multiple royalties shall not be due. Accordingly, no more than one royalty shall be due with respect to any unit of Licensed Product. Further no royalty shall be due with respect to reasonable quantities of units of Licensed Product used solely for clinical trials, other internal research or development purposes or as samples or promotional goods.

6.6. Sublicense Receipts.

6.6.1. General. In addition, Licensee shall pay Harvard an amount equal to [**] percent ([**]%) of all Sublicense Receipts. Notwithstanding the foregoing, if a Sublicense is part of a transaction in which Licensee also conveys rights to technology or intellectual property other than the Licensed Patent Rights that is reasonably necessary for, or directed to, the discovery, development, manufacture, sale or importation of a Licensed Product, then Licensee will propose in good faith by written notice to Harvard a basis for allocation of the consideration received by Licensee and its Affiliates for such transaction between the Licensed Patent Rights and such other technology and intellectual property based on the relative value to be attributed to the Sublicense as part of the overall transaction. Such notice shall describe in reasonable detail the rationale for such allocation. If Harvard disputes the proposed allocation, then the provisions of Section 6.6.2 shall apply. The amount payable to Harvard under this Section 6.6 with respect to Sublicense Receipts received in connection with such transaction shall be determined by the following equation:

[**].

If Licensee receives Sublicense Receipts that are creditable against amounts payable by the relevant Sublicensee with respect to sales of Licensed Products, then any amount paid by Licensee to Harvard under this Section 6.6.1 on account of such Sublicense Receipts shall be creditable against any amounts payable by Licensee to Harvard under Section 6.5 with respect to such sales.

6.6.2. Disputes. In the event that Harvard disputes Licensee’s proposed allocation of Sublicense Receipts with respect to a particular transaction, Harvard shall notify Licensee within [**] days of receipt of the proposed allocation (the “Allocation Dispute Notice”), in which case senior executives of Licensee and Harvard shall promptly meet in an attempt to resolve such matter in good faith. If Licensee and Harvard are unable to so resolve such matter within [**] days of the Allocation Dispute Notice, then either Licensee or Harvard may by written notice to the other have such dispute referred for resolution by an independent expert with substantial experience in valuing biopharmaceutical transactions. The parties shall agree upon the appointment of such independent expert. Licensee shall bear the costs of such expert in making such resolution. Licensee and Harvard shall instruct the expert to provide a written allocation of the Sublicense Receipts for the particular transaction between the Licensed Patent Rights and the other relevant technology and intellectual property licensed or sublicensed in connection therewith

- 24 -

in such transaction within [**] days of the date of appointment. Each of Licensee and Harvard shall promptly provide to the expert in confidence such information in its possession and control as the expert may reasonably request in connection with such resolution. The written allocation of the expert, absent clear error, shall be binding upon the parties.

Harvard may exercise its rights under this Section 7.3 only [**] per audited party and only with reasonable prior notice to the audited party. Notwithstanding the foregoing, to the extent that Licensee does not have the right to grant Harvard the right to audit the records of any of its Sublicensees hereunder, Licensee shall obtain for itself such right and, at the request of Harvard, Licensee shall exercise such inspection right with respect to such Sublicensees, using an independent, certified public accountant acceptable to Harvard, and provide the results of such inspection for inspection by Harvard pursuant to this Section 7.3. In such event, Licensee shall bear the full cost of such audit regardless of whether an underpayment of any amount is revealed.

7.8. Confidentiality of Records. All materials and information disclosed to or reviewed by Harvard or DFCI, or the appointed agents of either pursuant to this Article 7 shall be considered Confidential Information in accordance with Section 12.6.

8.	Enforcement of Patent Rights.

8.1. Notice. In the event either Harvard or DFCI (on one hand) or Licensee (on the other) becomes aware of any possible or actual infringement of any Licensed Patent Rights relating to Licensed Products (collectively, an “Infringement”), that party shall promptly notify the other party (provided that Licensee shall notify Harvard) and provide it with details regarding such Infringement.

8.2. Suit by Licensee. Licensee shall have the first right, but not the obligation, to take action in the prosecution, prevention, or termination of any Infringement. Before Licensee commences an action with respect to any Infringement, Licensee shall consider in good faith the views of Harvard and potential effects on the public interest in making its decision whether to xxx. Should Licensee elect to bring suit against an infringer, Licensee shall keep Harvard reasonably informed of the progress of the action and shall give Harvard a reasonable opportunity in advance to consult with Licensee and offer its views about major decision affecting the litigation. Licensee shall give careful consideration to those views, but shall have the right to control the action, provided, however, that if Licensee fails to defend in good faith the validity and/or enforceability of the Licensed Patent Rights in the action or, or if Licensee’s license to a Valid Claim in suit terminates, Harvard may elect to take control of the action pursuant to Section 8.3. Should Licensee elect to bring suit against an infringer and either or both Licensors are joined as party plaintiff in any such suit, such Licensor(s) shall have the right to withhold approval of counsel selected by Licensee only upon its reasonable determination that a conflict of interest exists with such counsel.

Licensee shall not compromise or settle any such litigation that purports to limit the scope or validity of any Licensed Patents without the prior written consent of Harvard, which consent shall not be unreasonably withheld or delayed. In the event Licensee exercises its right to xxx pursuant to this Section 8.2, it shall first reimburse itself out of any sums recovered in such suit or in settlement thereof for all costs and expenses of every kind and character, including reasonable attorney’s fees, reasonably incurred in the prosecution of any such suit. If, after such reimbursement, any funds shall remain from said recovery, then Harvard shall receive an amount equal to [**]% of such funds and the remaining [**]% of such funds shall be retained by Licensee.

- 27 -

8.3. Suit by Harvard. If Licensee does not take action in the prosecution, prevention, or termination of any Infringement pursuant to Section 8.2 above, and has not commenced negotiations with the infringer for the discontinuance of said Infringement, within the earlier of (a) [**] days after receipt of notice to Licensee by Harvard of the existence of an Infringement and (b) [**] days prior to the last date by which any Infringement action may be filed against the infringer, Harvard may elect to do so; provided that Harvard shall consider in good faith the grounds, if any, that Licensee may have had for not taking such action and any request by Licensee to delay or forego such action. Should Harvard elect to bring suit against an infringer and Licensee is joined as party plaintiff in any such suit, Licensee shall have the right to withhold approval of counsel selected by Harvard only upon its reasonable determination that a conflict of interest exists with such counsel. If Licensee withholds such approval due to a reasonable determination that a conflict of interest exists with the counsel selected by Harvard, then Harvard shall have the option to keep such counsel selected by Harvard and to provide separate counsel for Licensee at Harvard’s expense. The expenses of such suit or suits that Harvard elects to bring, including any expenses of Licensee incurred in conjunction with the prosecution of such suits or the settlement thereof, shall be paid for entirely by Harvard and Harvard shall hold Licensee free, clear and harmless from and against any and all costs of such litigation, including attorney’s fees, in each case incurred at the request of Harvard. Harvard shall not compromise or settle such litigation that purports to limit the scope or validity of any Licensed Patents without the prior written consent of Licensee, which consent shall not be unreasonably withheld or delayed. In the event Harvard exercises its right to xxx pursuant to this Section 8.3, it shall first reimburse itself out of any sums recovered in such suit or in settlement thereof for all costs and expenses of every kind and character, including reasonable attorney’s fees, reasonably incurred in the prosecution of any such suit. If, after such reimbursement, any funds shall remain from said recovery, then Licensee shall receive an amount equal to [**]% of such funds and the remaining [**]% of such funds shall be retained by Harvard.

8.4. Own Counsel. Each party shall always have the right to be represented by counsel of its own selection and at its own expense in any suit instituted under this Section 8 by another party for Infringement.

8.5. Cooperation. Each party agrees to cooperate fully in any action under this Section 8 which is controlled by another party, provided that the controlling party reimburses the cooperating parties promptly for any costs and expenses incurred by the cooperating parties in connection with providing such assistance.

8.6. Standing. If a party lacks standing and another party has standing to bring any such suit, action or proceeding, then such other party shall do so at the request of and at the expense of the requesting party. If a party determines that it is necessary or desirable for another party to join any such suit, action or proceeding, the other party shall execute all papers and perform such other acts as may be reasonably required in the circumstances.

8.7. Declaratory Judgment. If a declaratory judgment action is brought as an independent action naming Licensee and/or any of its Affiliates or Sublicensees as a defendant and alleging invalidity or unenforceability of any claims within the Licensed Patent Rights (except Joint Patent Rights), Licensee shall promptly notify Licensors in writing and Harvard and/or DFCI, as relevant based on ownership of the subject Licensed Patent Rights, may elect, upon

- 28 -

written notice to Licensee within [**] days after Licensors receive notice of the commencement of such action, to take over the sole defense of the invalidity or unenforceability aspect of the action at its/their own expense. If neither Harvard nor DFCI elect to take over the action, Licensee (and/or any of its Affiliates or Sublicensees, as applicable) shall have the right to control such action in its entirety at its own expense, in which case it shall keep Harvard and/or DFCI, as relevant, reasonably informed of the progress of the action and shall give Harvard and/or DFCI, as relevant, a reasonable opportunity in advance to consult and offer its/their views about major decisions affecting such defense, which views Licensee (and/or any of its Affiliates or Sublicensees, as applicable) shall consider in good faith. Licensee may elect to retain sole responsibility for defense of the invalidity and/or unenforceability aspect of any action alleging invalidity or unenforceability with respect to Joint Patent Rights at its own expense. No party responsible for handling the defense of a declaratory judgment action as specified in this Section 8.7 shall compromise or settle such litigation in any manner that purports to limit the scope or validity of any Licensed Patent Rights without the prior written consent of the owner(s) of such Licensed Patent Rights, which consent shall not be unreasonably withheld or delayed.

8.8. Paragraph IV Certification. Harvard and DFCI each shall inform Licensee of any certification regarding any Licensed Patent Rights received by it pursuant to 21 U.S.C. §§ 355(b)(2)(A)(iv) or (j)(2)(A)(vii)(IV) or successor provisions, or any similar provisions in a country other than the United States, and shall make reasonable efforts to provide Licensee with a copy of such certification within [**] business days of receipt. Licensors’ and Licensee’s rights with respect to the initiation and prosecution of any legal action in connection with such certification or any recovery obtained as a result of such legal action shall be as defined in Sections 8.2 though 8.4 above. Regardless of which party has the right to initiate and prosecute such action, the parties shall, as soon as practicable after receiving notice of such certification, convene and consult with each other regarding the appropriate course of conduct for such action. The initiating party shall keep the other parties fully informed and provide them with an opportunity to participate in decisions regarding the appropriate course of conduct for such action, as well as the right to join and participate in such action.

- 29 -

no representation that the practice of the Licensed Patent Rights or the manufacture, use or sale of any Licensed Product, or any element thereof, will not infringe the patent or proprietary rights of any third party.

9.2.2. Except as otherwise expressly provided in this Agreement, no party makes any warranty with respect to any technology, patents, goods, services, rights or other subject matter of this Agreement and hereby disclaims warranties of merchantability, fitness for a particular purpose and noninfringement with respect to any and all of the foregoing.

9.3. Limitation of Liability.

9.3.1.

10.1.1. Licensee shall indemnify, defend and hold harmless Licensors and their current or former directors, governing board members, trustees, officers, faculties, medical and professional staffs, employees, students, and agents and their respective successors, heirs and assigns (collectively, the “Indemnitees”) from and against any third party claim, liability, cost, expense, damage, deficiency, loss or obligation of any kind or nature (including, without limitation, reasonable attorney’s fees and other costs and expenses of litigation) (collectively, “Claims”), based upon, arising out of, or otherwise relating to the practice of any right or license under this Agreement by or on behalf of Licensee, any of its Affiliates, or any of its Sublicensees, including without limitation any cause of action relating to product liability concerning any product, process, or service made, used or sold pursuant to any right or license granted under this Agreement, except to the extent any such Claim is based on the gross negligence or willful misconduct of any Indemnitee.

HHMI and its trustees, officers, employees, and agents (collectively, “HHMI Indemnitees”) will be indemnified, defended by counsel acceptable to HHMI, and held harmless by the Licensee from and against any Claim, based upon, arising out of, or otherwise relating to this Agreement, including without limitation any cause of action relating to product liability. The previous sentence will not apply to any Claim that is determined with finality by a court of competent jurisdiction to result solely from the gross negligence or willful misconduct of an HHMI Indemnitee.

As a condition of indemnification under this Section 10, (a) the Indemnitees shall provide Licensee with prompt written notice of any claim, suit or action for which indemnification is sought (provided that the failure of Indemnitees so to notify Licensee will relieve Licensee from

- 30 -

liability for indemnification only to the extent Licensee is prejudiced by such delay); (b) the Indemnitees shall provide Licensee with the exclusive right to control the defense and settlement of such Claims, and Licensee shall not be obligated to indemnify any Indemnitee in connection with any settlement for any Claim unless Licensee previously consents in writing to such settlement; and (c) the Indemnitees shall cooperate fully with Licensee in such defense, at Licensee’s expense, and will permit Licensee to conduct and control such defense and the disposition of any such claim, suit, or action for which Licensee acknowledges it is fully responsible; provided that Licensee shall not settle any such claim, suit or action by admitting fault or liability on the part of the Licensors, or that would limit the scope or validity of any of the Licensed Patent Rights, without the prior written consent of Licensors, which consent shall not be unreasonably denied or delayed.

Notice of any claim for which indemnification may be sought pursuant to this Agreement shall be given reasonably promptly by HHMI following actual receipt of written notice thereof by an officer or attorney of HHMI. Notwithstanding the foregoing, the delay or failure of any HHMI Indemnitee to give reasonably prompt notice to Licensee of any such claim shall not affect the rights of such HHMI Indemnitee unless, and then only to the extent that, such delay or failure is prejudicial to or otherwise adversely affects Licensee. Licensee agrees not to settle any Claim against an HHMI Indemnitee without HHMI’s written consent, where (a) such settlement would include any admission of liability on the part of any HHMI Indemnitee, (b) such settlement would impose any restriction on any HHMI Indemnitee’s conduct of any of its activities, or (c) such settlement would not include an unconditional release of all HHMI Indemnitees from all liability for claims that are the subject matter of the settled Claim.

10.1.2. Licensee shall, at its own expense, provide attorneys reasonably acceptable to Harvard to defend against any actions brought or filed against any Indemnitee hereunder with respect to the subject of indemnity contained herein, whether or not such actions are rightfully brought. Licensee shall, at its own expense, provide attorneys reasonably acceptable to HHMI to defend against any actions brought or filed against any HHMI Indemnitee hereunder with respect to the subject of indemnity contained herein, whether or not such actions are rightfully brought.

10.2. Insurance.

10.2.1. Beginning at the time any Licensed Product is being commercially distributed or sold (other than for the purpose of obtaining regulatory approvals) by Licensee, or by an Affiliate, Sublicensee or agent of Licensee, Licensee shall, at its sole cost and expense, procure and maintain commercial general liability insurance in amounts not less than $[**] per incident and $[**] annual aggregate and naming the Licensors and HHMI as additional insureds. During clinical trials of any Licensed Product, Licensee shall, at its sole cost and expense, procure and maintain commercial general liability insurance in such equal or such lesser amount as Harvard shall require, naming the Licensors and HHMI as additional insureds. Such commercial general liability insurance shall provide; (a) product liability coverage and (b) broad form contractual liability coverage for Licensors’ and HHMI’s indemnification under this Agreement.

10.2.2. If Licensee elects to self-insure all or part of the limits described above in Section 10.2.1 (including deductibles or retentions which are in excess of $[**] annual aggregate) such self-insurance program must be acceptable to Harvard and the Risk Management Foundation

- 31 -

of the Harvard Medical Institutions, Inc. in their sole discretion. The minimum amounts of insurance coverage required shall not be construed to create a limit of Licensee’s liability with respect to its indemnification under this Agreement.

10.2.3. Licensee shall provide Harvard with written evidence of such insurance upon request of Licensors. Licensee shall provide Licensors with written notice at least [**] days prior to the cancellation, non-renewal or material change in such insurance; if Licensee does not obtain replacement insurance providing comparable coverage within such [**] day period, Licensors shall have the right to terminate this Agreement effective at the end of such [**] day period without notice or any additional waiting periods.

11.2.2.2.

- 32 -

accordance with the procedure set forth in clauses (i) through (iv) below. For the purposes of this Section 11.2.2.3, a “Bona Fide Dispute” shall be deemed to exist if Licensee believes in good faith that it is not required to pay the sums in dispute and has placed the sums in dispute or other sufficient collateral in escrow in a manner reasonably acceptable to Harvard until the dispute is resolved.

(i) In the event of a Bona Fide Dispute, upon written request by either party to the other party, the parties shall promptly negotiate in good faith to appoint a mutually acceptable, disinterested, conflict-free individual not affiliated with either party to resolve such dispute (an “Arbitrator”). If the parties are not able to agree within [**] business days after the receipt of the written request in the immediately preceding sentence, either party may request the appointment of an arbitrator on a expedited basis by the American Arbitration Association, sitting in Boston, with relevant commercial experience, from its panel of arbitrators.

Each party shall have [**] days from receipt of the other party’s statement to submit a written response, which shall include any technical information in support of such response. The Arbitrator shall have the right to meet with the parties, either alone or together, as necessary to make a determination.

(iii) No later than [**] days after the designation of the Arbitrator, the Arbitrator shall render his/her decision, and s/he shall provide the parties with a written statement setting forth the basis of the decision.

(iv) In the event that the Arbitrator rules in favor of Harvard, Licensee shall reimburse Harvard in full for Harvard’s share of the fees and costs of the Arbitrator and for all of Harvard’s reasonable out-of-pocket expenses (including attorneys fees) incurred in connection with the arbitration proceedings. In addition, Licensee shall pay Harvard interest on the amount awarded, if any, in accordance with Section 7.4.

11.2.2.4. If Licensee defaults in its obligations under Section 10.2 to procure and maintain insurance or, if Licensee has in any event failed to comply with the notice requirements contained therein, then Licensors may terminate this Agreement if Licensee has not cured such default or failure within [**] days of written notice thereof from Licensors.

11.2.3. Diligence. Harvard shall have the right to terminate this Agreement in accordance with the provisions of Section 5.5.

11.2.4. Bankruptcy. Licensors may terminate this Agreement upon notice to Licensee if Licensee is adjudged insolvent or bankrupt, applies for judicial or extra-judicial settlement with its creditors, makes an assignment for the benefit of its creditors, voluntarily files for bankruptcy or has a receiver or trustee (or the like) in bankruptcy appointed by reason of its insolvency, or in the event an involuntary bankruptcy action is filed against Licensee and not dismissed within ninety (90) days, or if Licensee becomes the subject of liquidation or dissolution proceedings or otherwise discontinues doing business generally.

12.2. No Security Interest. Licensee shall not enter into any agreement under which Licensee grants to or otherwise creates in any third party a security interest in this Agreement or any of the rights granted to Licensee herein. Any grant or creation of a security interest purported or attempted to be made in violation of the terms of this Section 12.2 shall be null and void and of no legal effect.

12.3. Disclosure of Agreement. Neither party will make any public announcement regarding this Agreement without the prior written approval of the other party, provided that each party may disclose the terms of this Agreement to the extent required, in the reasonable opinion of its legal counsel, to comply with applicable laws, or in confidence to its current or prospective partners, investors, accountants and agents.

- 34 -

12.4. Use of Name. Licensee shall not, and shall ensure that its Affiliates and Sublicensees shall not, use the name or insignia of Harvard or DFCI or the name of any of Harvard’s or DFCI’s officers, faculty, other researchers or students, or any adaptation of such names, in any advertising, promotional or sales literature, including without limitation any press release or any document employed to obtain funds, without the prior written approval of Harvard or DFCI, as applicable. This restriction shall not apply to any information required by law to be disclosed to any governmental entity.

12.5. Supersedes Original Agreement; Entire Agreement. The parties acknowledge and agree that the Original Agreement is hereby terminated in its entirety as of the Effective Date. As of the Effective Date, this Agreement replaces and supersedes the Original Agreement in its entirety. Accordingly notwithstanding anything in the Original Agreement to the contrary none of the terms or conditions of the Original Agreement shall survive such termination. Notwithstanding the foregoing, any of Licensee’s obligations under the Original Agreement which accrued prior to the Effective Date will survive termination of the Original Agreement. This Agreement is the sole agreement with respect to the subject matter hereof and, except as expressly set forth herein, supersedes all other agreements and understandings between the parties with respect to the same.

12.6. Notices. Unless otherwise specifically provided, all notices required or permitted by this Agreement shall be in writing and may be delivered personally, or may be sent by facsimile

Except pursuant to a written agreement wherein such assignee acknowledges the terms and conditions of this Agreement and agrees to be bound by the applicable terms hereof and with prior written notice to Licensee identifying the proposed assignee, neither Licensor shall assign any of its rights to the Licensed Patent Rights to any third party.

12.13. Force Majeure. Neither party will be responsible for delays resulting from causes beyond the reasonable control of such party, including without limitation fire, explosion, flood, war, strike, or riot, provided that the nonperforming party uses commercially reasonable efforts to avoid or remove such causes of nonperformance and continues performance under this Agreement with reasonable dispatch whenever such causes are removed.

12.14. Interpretation. The parties hereto acknowledge and agree that: (i) each party and its counsel reviewed and negotiated the terms and provisions of this Agreement and have contributed to its revision; (ii) the rule of construction to the effect that any ambiguities are resolved against the drafting party shall not be employed in the interpretation of this Agreement; and (iii) the terms and provisions of this Agreement shall be construed fairly as to both parties hereto and not in favor of or against either party, regardless of which party was generally responsible for the preparation of this Agreement.

12.15. Severability. If any provision of this Agreement is or becomes invalid or is ruled invalid by any court of competent jurisdiction or is deemed unenforceable, it is the intention of the parties that the remainder of this Agreement shall not be affected.

nature of such Confidential Information and who need to know such Confidential Information for the purposes of this Agreement: (ii) use such Confidential Information solely for the purposes of this Agreement; and (iii) allow its trustees or directors, officers, employees, consultants, auditors, and advisors to reproduce the Confidential Information only to the extent necessary for the purposes of this Agreement with all such reproductions being considered Confidential Information.

12.16.2. Exceptions.

12.17. Third Party Beneficiary Status.

12.17.1.
