5. REPORTS AND RECORD KEEPING

5.1 Frequency of Reports.

(a) Before First Commercial Sale. Prior to the first commercial sale to an end user purchaser of any LICENSED PRODUCT or first commercial performance of any LICENSED PROCESS, COMPANY shall deliver reports to WHITEHEAD annually, within [***] days of the end of each calendar year, containing information concerning the immediately preceding calendar year, as further described in Section 5.2.

5.2 Content of Reports and Payments. Each report delivered by COMPANY to WHITEHEAD shall contain at least the following information for the immediately preceding REPORTING PERIOD or calendar year, as applicable:

21

If no amounts are due for any REPORTING PERIOD, the report shall so state. Each report provided to WHITEHEAD under this Section 5 shall be treated as confidential information of COMPANY and not disclosed or used by WHITEHEAD other than to confirm COMPANY’s compliance with its reporting obligations under this Section 5, to exercise its rights under this Agreement, and to provide such report to employees of HHMI and trustees who have a need to know such information.

5.3 Financial Statements. On or before the [***] day following the close of COMPANY’s fiscal year, COMPANY shall provide WHITEHEAD with COMPANY’s financial statements for the preceding fiscal year including, at a minimum, a balance sheet and an income statement, certified by COMPANY’s treasurer or chief financial officer or by an independent auditor.

5.4 Record keeping. COMPANY shall maintain, and shall cause its AFFILIATES and SUBLICENSEES to maintain, complete and accurate records relating to the rights and obligations under this Agreement and any amounts payable to WHITEHEAD in relation to this Agreement, which records shall contain sufficient information to permit WHITEHEAD to confirm the accuracy of any reports delivered to WHITEHEAD and compliance in other respects with this Agreement. The relevant party shall retain such records for at least three (3) years following the end of the calendar year to which they pertain, during which time WHITEHEAD or WHITEHEAD’s appointed agents, shall have the right, at WHITEHEAD’s expense, to inspect such records during normal business hours to verify any reports and payments made or compliance in other respects under this Agreement. In the event that any audit performed under this Section reveals an underpayment in excess [***] for any twelve (12) month period,

6. PATENT PROSECUTION

6.1 Responsibility for PATENT RIGHTS. WHITEHEAD shall prepare, file, prosecute, and maintain all of the PATENT RIGHTS. COMPANY shall have reasonable advance opportunities to advise WHITEHEAD and shall cooperate with WHITEHEAD in such filing, prosecution and maintenance. WHITEHEAD will consult with COMPANY on the prosecution of the PATENT RIGHTS and COMPANY’s suggestions and requests regarding patent prosecution will be reasonably considered and included unless WHITEHEAD reasonably concludes in good faith that they are not beneficial to the PATENT RIGHTS. WHITEHEAD shall keep COMPANY timely informed with regard to the provisional application, patent application and maintenance processes. WHITEHEAD shall deliver to COMPANY copies of all provisional applications, patent applications, amendments, related correspondence, and other related matters in a timely manner, both for United States and international (non-United States) filings. Notwithstanding anything herein to the contrary, on a country-by-country basis, if COMPANY notifies WHITEHEAD in writing of COMPANY’s objection to any such filing, prosecution or maintenance with respect to any provisional application(s) or patent application(s) within the scope of PATENT RIGHTS, such provisional application(s) and patent application(s) shall thereafter not qualify as PATENT RIGHTS hereunder with respect to the particular country in question, and COMPANY shall not be responsible for patents costs or expenses of such provisional application(s) and patent application(s) incurred thereafter.

6.2 International (non-United States) Filings. Appendix D is a list of countries in which patent applications corresponding to the United States patent applications and provisional applications listed in Appendix A shall be filed, prosecuted, and maintained. Appendix D may be amended by mutual agreement of COMPANY and WHITEHEAD.

23

6.3 Payment of Expenses. Payment of all reasonable out-of-pocket fees and costs, including attorneys’ fees, relating to the filing, prosecution and maintenance of the PATENT RIGHTS shall be the responsibility of COMPANY, whether such amounts were incurred before or after the EFFECTIVE DATE but not after the Term. As of October 15, 2015, WHITEHEAD, UC and UW have incurred $[***] for such patent-related fees and costs. (Such amount includes fees and costs invoiced prior to October 15, 2015. Additional fees and costs may be invoiced after such date, which will be for COMPANY’s account.) WHITEHEAD shall invoice COMPANY for $[***] of such costs upon execution of this Agreement, and for $[***] on the first anniversary of execution of this Agreement. COMPANY shall reimburse all amounts due pursuant to this Section 6.3 within [***] days of invoicing; late payments shall accrue interest pursuant to Section 4.2(c). In the event that WHITEHEAD licenses the PATENT RIGHTS in a field separate from the FIELD to a third party, where possible, a reasonable adjustment to COMPANY’s patent reimbursement payment shall be made to account for such third party license. In all instances, WHITEHEAD shall pay the fees prescribed for large entities to the United States Patent and Trademark Office.

7. INFRINGEMENT

7.1 Notification of Infringement. Each Party agrees to provide written notice to the other Party promptly after becoming aware of any infringement of the PATENT RIGHTS.

7.2 Right to Prosecute Infringements.

(a) COMPANY Right to Prosecute. So long as COMPANY remains the exclusive licensee of the PATENT RIGHTS in the FIELD in the TERRITORY, COMPANY, to the extent permitted by law, shall have the right, under its own control and at its own expense, to prosecute any third party infringement of the PATENT RIGHTS in the FIELD in the TERRITORY, subject to Sections 7.4 and 7.5. If required by law, WHITEHEAD shall permit any action under this Section to be brought in its name, including being joined as a party-plaintiff, provided that COMPANY shall reimburse WHITEHEAD for any reasonable out-of-pocket costs WHITEHEAD incurs in connection with such action.

24

Prior to commencing any such action, COMPANY shall consult with WHITEHEAD and shall consider the views of WHITEHEAD regarding the advisability of the proposed action and its effect on the public interest. COMPANY shall not enter into any settlement, consent judgment, or other voluntary final disposition of any infringement action under this Section which imposes obligations on WHITEHEAD or MIT beyond those set forth herein, or which invalidates or restricts the PATENT RIGHTS, without the prior written consent of WHITEHEAD (subject to concurrence of MIT, as applicable), which consent shall not be unreasonably withheld or delayed.

(b) WHITEHEAD Right to Prosecute. In the event that COMPANY is unsuccessful in persuading the alleged infringer to desist or fails to have initiated an infringement action within a reasonable time after COMPANY first becomes aware of the basis for such action, WHITEHEAD shall have the right, at its sole discretion, to prosecute such infringement under its sole control and at its sole expense, and any recovery obtained shall belong to WHITEHEAD.

7.3 Declaratory Judgment Actions. In the event that a PATENT CHALLENGE is brought against WHITEHEAD or COMPANY by a third party (including without limitation oppositions, reissues, interferences, reexaminations and other litigation-like proceedings), COMPANY, at its option, shall have the right within [***] days after commencement of such action to take over the sole defense of the action at its own expense subject to Sections 7.4 and 7.5. If COMPANY does not exercise this right, WHITEHEAD may take over the sole defense of the action at WHITEHEAD’s sole expense, subject to Sections 7.4 and 7.5. In the event such a PATENT CHALLENGE results in the filing of an infringement counterclaim, then any recovery obtained from such a counterclaim shall be distributed in accordance with Section 7.5.

7.4 Offsets. COMPANY may offset a total of [***] of any expenses incurred (whether by COMPANY or by WHITEHEAD reimbursed by COMPANY pursuant to Section 7.2(a)) under Sections 7.2 or 7.3 against any payments due to WHITEHEAD under Article 4, provided that in no event shall such payments under Article 4, when aggregated with any other offsets and credits allowed under this Agreement, be reduced by more than [***] in any REPORTING PERIOD. If such [***] of COMPANY’s expenses and costs exceeds the amount of payments deducted by COMPANY for any REPORTING PERIOD, then COMPANY may to that extent reduce the payments due to WHITEHEAD in succeeding REPORTING PERIODS, but never by more than [***] of the total payments due in any one calendar year with respect to the patent(s) and patent application(s) subject to such suit.

25

7.5 Recovery. Any recovery obtained in an action brought by the COMPANY under Sections 7.2 or 7.3 shall be distributed as follows:

7.6 Cooperation. Each Party agrees to cooperate in any action under this Article which is controlled by any other 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.

7.7 Right to Sublicense. So long as COMPANY remains the exclusive licensee of the PATENT RIGHTS in the FIELD in the TERRITORY, COMPANY shall have the sole right to sublicense any alleged infringer in the FIELD in the TERRITORY for future use of the PATENT RIGHTS in accordance with the terms and conditions of this Agreement relating to sublicenses. Any upfront fees as part of such sublicense shall be treated as set forth in Article 4.

26

8. INDEMNIFICATION AND INSURANCE

8.1 Indemnification.

(a) Indemnity. COMPANY shall indemnify, defend, and hold harmless WHITEHEAD, UM, MIT, ARIZONA, UW and UC, and the trustees (including the Curators of UM, the Arizona Board of Regents, the University of Washington Board of Regents and the members of the MIT Corporation), officers, faculty, students, employees, and agents of each of them, and their respective successors, heirs and assigns (the “Indemnitees”), against any liability, damage, loss, or expense (including reasonable attorneys’ fees and expenses) (collectively, “Losses”) incurred by or imposed upon any of the Indemnitees in connection with any third party claims, suits, actions or demands arising out of or based upon the exercise of any rights granted to COMPANY under this Agreement or any breach of this Agreement by COMPANY. COMPANY’S indemnification under this Section 8.1(a) does not apply to any Losses to the extent that they are attributable to the grossly negligent or willful activities of any of the Indemnitees, or to the intentional wrongdoing or intentional misconduct of any of the Indemnitees.

(b) Indemnification of HHMI. HHMI, and its trustees, officers, employees, and agents (collectively, “HHMI Indemnitees”), will be indemnified, defended by counsel acceptable to HHMI, and held harmless by COMPANY from and against any claim, liability, cost, expense, damage, deficiency, loss, or obligation, of any kind or nature (including, without limitation, reasonable attorneys’ fees and other costs and expenses of defense) (collectively, “Claims”), based upon, arising out of, or otherwise relating to this Agreement or any sublicense, or the use, handling, storage, or disposition of the TANGIBLE PROPERTY by COMPANY or others who possess the TANGIBLE PROPERTY through a chain of possession leading back, directly or indirectly, to COMPANY, 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. Notwithstanding any other provision of this Agreement, COMPANY’s obligations to defend, indemnify and hold harmless the HHMI Indemnitees under this paragraph will not be subject to any limitation or exclusion of liability or damages or otherwise limited in any way.

27

(c) Procedures. The Indemnitees agree to provide COMPANY with prompt written notice of any claim, suit, action, or demand for which indemnification is sought under Section 8.1(a) of this Agreement. COMPANY agrees, at its own expense, to provide attorneys reasonably acceptable to Indemnitees to defend against any such claim. The Indemnitees shall cooperate fully with COMPANY in such defense and will permit COMPANY to conduct and control such defense and the disposition of such claim, suit, or action (including all decisions relative to litigation, appeal, and settlement); provided, however, that any Indemnitee shall have the right to retain its own counsel, at the expense of COMPANY, if representation of such Indemnitee by the counsel retained by COMPANY would be inappropriate because of actual or potential differences in the interests of such Indemnitee and any other party represented by such counsel. COMPANY agrees to keep WHITEHEAD reasonably informed of the progress in the defense and disposition of such claim and to consult reasonably with WHITEHEAD with regard to any proposed settlement.

8.2 Insurance. COMPANY shall obtain and carry in full force and effect commercial general liability insurance and, beginning at the time any PRODUCT is being commercially manufactured, distributed or sold by, or any LICENSED PROCESS is being performed commercially by, COMPANY or by an AFFILIATE or SUBLICENSEE, product liability and errors and omissions insurance. Such insurance:

In addition, the COMPANY shall obtain and carry in full force and effect general liability insurance, including products liability insurance, and errors and omissions insurance for the conduct of all clinical trials involving human subjects by no later than the commencement thereof. Such insurance shall comply with subsections (ii) and (iii) above.

28

All product liability insurance policies shall be occurrence-based policies. All errors and omissions liability policies shall have endorsements to cover bodily injury and damage to tangible property and shall have “retroactive dates” of the earliest to occur of the events described in subclauses (i) and (ii) of the last paragraph of this Section 8.2 and shall continue for the time durations specified in such last paragraph.

The limits of such insurance shall not be less than [***] per occurrence with an aggregate of [***] bodily injury including death; and [***] per occurrence with an aggregate of [***] for property damage. In the alternative, COMPANY may self-insure subject to prior approval of WHITEHEAD, MIT, UM, ARIZONA, UW and UC. COMPANY shall provide WHITEHEAD with Certificates of Insurance evidencing compliance with this Section. COMPANY shall continue to maintain such insurance or self-insurance after the expiration or termination of this Agreement during any period in which COMPANY or any AFFILIATE or SUBLICENSEE continues (i) to commercially manufacture, distribute or sell a product that was a PRODUCT under this Agreement or (ii) to perform commercially a service that was a LICENSED PROCESS under this Agreement, and, in both cases, thereafter for a period of ten (10) years.

9. REPRESENTATIONS OR WARRANTIES

WHITEHEAD hereby represents and warrants that (a) it has the power and authority to grant the licenses provided for herein to COMPANY, and that it has not earlier granted, or assumed any obligation to grant, any rights in the PATENT RIGHTS to any third party that would conflict with the rights granted to COMPANY herein; and (b) this Agreement constitutes the legal, valid and binding obligation of WHITEHEAD, enforceable against WHITEHEAD in accordance with its terms.

EXCEPT AS MAY OTHERWISE BE EXPRESSLY SET FORTH IN THIS AGREEMENT, WHITEHEAD, UM, MIT, ARIZONA, UW AND UC MAKE NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE PATENT RIGHTS, TANGIBLE PROPERTY OR KNOW-HOW, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A

29

PARTICULAR PURPOSE, NONINFRINGEMENT, VALIDITY OF PATENT RIGHTS CLAIMS, WHETHER ISSUED OR PENDING, AND THE ABSENCE OF LATENT OR OTHER DEFECTS, WHETHER OR NOT DISCOVERABLE. Specifically, and not to limit the foregoing, WHITEHEAD, UM, MIT, ARIZONA, UW and UC make no warranty or representation, except as expressly set forth in this Agreement, (i) regarding the validity or scope of the PATENT RIGHTS, and (ii) that the exploitation of the PATENT RIGHTS, TANGIBLE PROPERTY or any LICENSED PRODUCT or LICENSED PROCESS will not infringe any patents or other intellectual property rights of WHITEHEAD, UM, MIT, ARIZONA, UC, UW or of a third party.

IN NO EVENT SHALL COMPANY, OR WHITEHEAD, UM, MIT, ARIZONA, UW OR UC, OR THE TRUSTEES, DIRECTORS, OFFICERS, EMPLOYEES AND AFFILIATES OF ANY OF THEM, BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY KIND, INCLUDING ECONOMIC DAMAGES OR INJURY TO PROPERTY AND LOST PROFITS, REGARDLESS OF WHETHER COMPANY, WHITEHEAD, UM, MIT, ARIZONA OR UC SHALL BE ADVISED, SHALL HAVE OTHER REASON TO KNOW, OR IN FACT SHALL KNOW OF THE POSSIBILITY OF THE FOREGOING.

The TANGIBLE PROPERTY is experimental in nature and will be used with prudence and appropriate caution, since not all of its characteristics are known.

10. ASSIGNMENT

This Agreement is personal to COMPANY and no rights or obligations may be assigned by COMPANY without the prior written consent of WHITEHEAD. The foregoing notwithstanding, COMPANY may assign its rights and obligations under this Agreement (a) to an Affiliate, and (b) to a successor in connection with the merger, consolidation, or sale of all or substantially all of its assets or that portion of its business to which this Agreement relates; provided, however, that such assignee shall agree in writing to be bound by the terms and conditions of this Agreement as if the Affiliate or successor, as applicable, were COMPANY under this Agreement on or before the effective date of the assignment.

30

11. GENERAL COMPLIANCE WITH LAWS

COMPANY hereby gives written assurance that it will comply with, and will cause its AFFILIATES and SUBLICENSEES to comply with, all United States export control laws and regulations, that it bears sole responsibility for any violation of such laws and regulations by itself or its AFFILIATES or SUBLICENSEES, and that it will indemnify, defend, and hold WHITEHEAD, MIT and HHMI harmless (in accordance with Section 8.1) for the consequences of any such violation.

11.3 Non-Use of Name.

32

12.4 Termination as a Consequence of Patent Challenge.

(b) By SUBLICENSEE. If a SUBLICENSEE brings a PATENT CHALLENGE or assists another party in bringing a PATENT CHALLENGE (except as required under a court order or subpoena), then WHITEHEAD may send a written demand to COMPANY to end the PATENT CHALLENGE or terminate such sublicense as the COMPANY may choose.

The Parties agree that any dispute arising out of or relating to this Agreement shall be resolved solely by means of the procedures set forth in this Article, and that such procedures constitute legally binding obligations that are an essential provision of this Agreement. If any Party fails to observe the procedures of this Article, as may be modified by their written agreement, the other Parties may bring an action for specific performance of these procedures in any court of competent jurisdiction.

13.2 Equitable Remedies. Although the procedures specified in this Article are the sole and exclusive procedures for the resolution of disputes arising out of or relating to this Agreement, any Party may seek a preliminary injunction or other provisional equitable relief if, in its reasonable judgment, such action is necessary to avoid irreparable harm to itself or to preserve its rights under this Agreement.

13.3 Dispute Resolution Procedures.

(a) Mediation. In the event any dispute arising out of or relating to this Agreement remains unresolved within [***] days from the date the affected Party informed the other Parties of such dispute, any Party may initiate mediation upon written notice to the other Party (“Notice Date”), whereupon all Parties shall be obligated to engage in a mediation proceeding under the then current Center for Public Resources (“CPR”) Model Procedure for Mediation of Business Disputes (http://www.cpradr.org), except that specific provisions of this Article shall override inconsistent provisions of the CPR Model Procedure. The mediator will be selected from the CPR Panels of Neutrals. If the Parties cannot agree upon the selection of a mediator within [***] days after the Notice Date, then upon the request of any Party, the CPR shall appoint the mediator. The Parties shall attempt to resolve the dispute through mediation until the first of the following occurs:

34

(b) Trial Without Jury. If the Parties fail to resolve the dispute through mediation, or if no Party elects to initiate mediation, each Party shall have the right to pursue any other remedies legally available to resolve the dispute, provided, however, that the Parties expressly waive any right to a jury trial in any legal proceeding under this Article.

13.4 Performance to Continue. Each Party shall continue to perform its undisputed obligations under this Agreement pending final resolution of any dispute arising out of or relating to this Agreement; provided, however, that a Party may suspend performance of its undisputed obligations during any period in which any other Party fails or refuses to perform its undisputed obligations.

36

14.4 Amendment and Waiver. This Agreement may be amended, supplemented, or otherwise modified only by means of a written instrument signed by all Parties. Any waiver of any rights or failure to act in a specific instance shall relate only to such instance and shall not be construed as an agreement to waive any rights or fail to act in any other instance, whether or not similar.

37

14.10 Interpretation. Whenever any provision of this Agreement uses the term “including” (or “includes”), such term shall be deemed to mean “including without limitation” (or “includes without limitations”). “Herein,” “hereby,” “hereunder,” “hereof” and other equivalent words refer to this Agreement as an entirety and not solely to the particular portion of this Agreement in which any such word is used.
