2.7Sublicensing. LICENSEE has the right to grant sublicenses under this Agreement consistent with the terms and conditions of this Agreement. LICENSEE remains responsible for the operations of any Sublicensee under this Agreement, as if the operations were carried out by LICENSEE.

2.7.1

Notice. LICENSEE shall promptly notify DFCI in writing of the identity of any prospective Sublicensee at the time that LICENSEE enters into a binding term sheet or final sublicense with such prospective Sublicensee.

2.7.2

Form and Content of Sublicenses. LICENSEE shall issue any sublicense(s) granted by it under this Agreement in writing and shall attach a copy of this Agreement to all sublicenses.

The first year in which the cumulative and aggregated Net Sales for all Licensed Products by LICENSEE, Affiliates, and Sublicensees, on a worldwide basis exceeds a total of one billion dollars ($1,000,000,000)	$[ * ]

3.1.5

Running Royalties. LICENSEE shall pay DFCI the following running royalties as set forth below:

(a)

LICENSEE, its Affiliates, or its Sublicensees shall pay DFCI a [ * ] royalty on the Net Sales of Licensed Products or a Licensed Process in the Field of Use. Such royalty rate shall not be subject to any form of royalty stacking reduction. It is also expressly understood that even if a Licensed Product or Licensed Process would, but for the license granted under this Agreement, infringe multiple claims included under Patent Rights, the royalty shall not be additive and shall not exceed the royalty stated in this Section 3.1.5(a).

(b)

For any Licensed Product or Licensed Process covered solely by a claim in a pending patent application included in the Patent Rights, LICENSEE, its Affiliates, or its Sublicensees shall have the right to deduct from the royalty payment due DFCI, as specified above in Section 3.1.5(a), fifty percent (50%) of such royalty payment. The unpaid royalty payment balance in each territory shall be due and payable by LICENSEE to DFCI sixty (60) days after such claim is issued or granted in such territory.

3.1.6

Sublicense Fees. For each sublicense granted by LICENSEE to a Sublicensee in the Field of Use, LICENSEE shall pay to DFCI the sum of [ * ] for each fully executed sublicense executed after the Effective Date of this Agreement that grants rights to one or more Licensed Products in the Field of Use to be paid thirty (30) days from the date of full execution of that sublicense.

3.1.7

Maintenance Fees. Upon the achievement of certain events by LICENSEE specified below, LICENSEE will pay to DFCI; (i) an annual license maintenance fee and (ii) an equivalent sublicense maintenance fee for each fully executed sublicense in effect, collectively the “Maintenance Fees”. Such Maintenance Fees

shall be due beginning on the first anniversary date of this Agreement and due annually thereafter on the anniversary date:


EVENT	MAINTENANCE FEE
After the issuance in the United States of the first patent within Patent Rights claiming subject matter in the Field of Use	$[ * ]
After (i) the issuance in the United States and (ii) grant in an EPO member state and Japan of the first patent within Patent Rights claiming subject matter in the Field of Use	$[ * ]

Notwithstanding the foregoing, no license maintenance fee will be due after LICENSEE, an Affiliate, or Sublicensee begins to commercially sell a Licensed Product. For the avoidance of doubt, the above fees are triggered by the first issuance of a patent in the Field of Use and not due for each issuance of a patent in the Field of Use.

The fees specified in this Section 3.1.7 are not refundable, not creditable, and not an advance against any fees, royalties, or reimbursement of any costs incurred hereunder.

3.2Waiver or Deferral. Waiver or deferral by DFCI of any payment owed under any paragraph under Section 3.1 may not be construed as a waiver or deferral of any subsequent payment owed by LICENSEE to DFCI.

3.3Combination Packages. If a Licensed Product in the Field of Use is sold in a combination package or kit containing other active products or processes, then Net Sales for purposes of determining royalty payments on the combination package will be calculated using one of the following methods, but the royalties payable to DFCI may not be reduced to less than [ * ] of that provided for in Section 3.1.5 (a) of this Agreement:

By multiplying the net selling price of the combination by the fraction A/A+B, where A is the gross selling price, during the royalty-paying period in question, of the Licensed Product sold separately, and B is the gross selling price during the royalty period in question, of the other active products sold separately; or

If no separate sales are made of the Licensed Product or any of the active products in such combination package during the royalty-paying period in question, Net Sales for the purposes of determining royalty payments, must be calculated by dividing the net selling price of the combination by the number of functions performed by the combination sold where such combination contains active agents other than those licensed under this Agreement.

Article 4 - Royalty Reports, Payments and Financial Records

4.1Royalty Reports. Within sixty (60) days after March 31, June 30, September 30, and December 31, of each year in which this Agreement is in effect, LICENSEE shall deliver to DFCI full, true and accurate reports of its activities and those of its Affiliates, if any, relating to this Agreement during the preceding three (3) month period. LICENSEE shall deliver reports containing equivalent information pertaining to its Sublicensee(s) within sixty (60) days of receipt of a royalty report from such Sublicensee (“Sublicensee Report”). Notwithstanding the foregoing,

LICENSEE shall have the option to provide such Sublicensee reports either individually or as a consolidated report and shall provide such reports no less frequently than every six (6) months. All reports must include at least the following:

(i)

An accounting of amounts invoiced but not yet received by FibroGen pursuant to Section 1.9(e).

With each report, LICENSEE shall pay to DFCI the royalties due and payable. If no royalties are due, LICENSEE shall so report. If multiple Licensed Products are covered by the license granted under this Agreement, LICENSEE shall separately identify each Licensed Product in the royalty report and specify which Licensed Intellectual Property covers that Licensed Product.

Ninety (90) days following any such payment, LICENSEE shall take reasonable business efforts to make any necessary adjustments (including any necessary credits, and offsets) to ensure that the amount paid to DFCI is in compliance with the terms of this Agreement.

4.2Record Keeping.

4.2.1

Books and Records. LICENSEE shall keep, and shall require its Affiliates and Sublicensees to keep, true books of account containing an accurate record (together with supporting documentation) of all data necessary for determining the amounts payable to DFCI. LICENSEE shall keep its records at its principal place of business or the principal place of business of the appropriate division of LICENSEE to which this Agreement relates and shall require its Affiliates and Sublicenses to keep their books and records in the same manner.

4.2.2

Inspections. In order for DFCI to determine the correctness of any report or payment made under this Agreement, LICENSEE shall make its records available

to DFCI for inspection, for a period of three (3) years following the end of the calendar year to which they pertain. LICENSEE shall also require any Affiliates or Sublicensees to make their records available for inspection by DFCI, in the same manner as provided in this Section 4.2.2.

DFCI may inspect the records during regular business hours by a certified public accountant selected by DFCI and reasonably acceptable to the licensed entity whose records are being inspected. In conducting inspections under this Section 4.2.2, LICENSEE agrees that DFCI’s accountant may have access to all records which DFCI reasonably believes to be relevant to calculating royalties owed to DFCI under Article 3.

DFCI is responsible for the cost of any inspection, unless the examination shows an underreporting or underpayment by any entity in excess of five percent for any twelve (12) month period, in which case LICENSEE shall pay the cost of the inspection as well as any additional sum that would have been payable to DFCI had the LICENSEE reported correctly, plus interest as set forth in Section 4.5.

4.3Form of Payments and Taxes. LICENSEE must make all payments to be made to DFCI in Boston, Massachusetts, or at such other place or in such other way as DFCI may reasonably designate. Payments must be paid by check or wire transfer.

LICENSEE shall pay all amounts payable to DFCI under this Agreement in United States funds. All taxes levied on payments accruing to DFCI under this Agreement shall be paid by DFCI from its own account, including taxes levied thereon as income to DFCI. Any withholding taxes imposed on any payments made to DFCI shall be deducted from the payments made to DFCI, paid to the proper taxing authority, and a receipt of payments of the tax secured and properly delivered to DFCI. Each party agrees to assist the other party in claiming exemption from such deductions or withholding under any double taxation or similar agreement or treaty from time to time in force. LICENSEE shall reasonably inform DFCI of any such taxes actually due on a payment owed to DFCI if LICENSEE becomes aware that such tax is due.

4.4Currency Conversion. If any currency conversion is required in connection with any payment owed to DFCI, the conversion will be made at the buying rate for the foreign currency as quoted by the Wall Street Journal on the last business day of the month to which such payment pertains.

4.5Interest. Any payment owed to DFCI under this Agreement that is not made when due will accrue interest beginning on the first day following the due date specified in Article 3. The interest will be calculated at the annual rate of the sum of (a) [ * ] plus (b), the prime interest rate quoted by Bank of America on the date the payment is due, the interest being compounded on the last day of each calendar quarter. However, the annual rate may not exceed the maximum legal interest rate in Massachusetts. The payment of interest as required by this Section does not foreclose DFCI from exercising any other rights or remedies it has as a consequence of the lateness of any payment.

Article 5 - Operations under the License

5.1.1

General Obligations. LICENSEE shall use commercially reasonable efforts to diligently use Licensed Intellectual Property to develop and commercialize a diagnostic or therapeutic Licensed Product(s) in the Field of Use.

At a minimum, LICENSEE shall include in these reports: (a) a summary of LICENSEE’s progress and (that of any Sublicensee) in the reporting year, related to exploiting the Licensed Intellectual Property including an identification of all Licensed Products that LICENSEE intends to develop, if any; and (b), a summary of all sublicenses that are currently in force and those that have been terminated, if any, in the reporting year.

5.1.3

Failure to Perform. LICENSEE’s failure to perform with any due diligence requirement provided in any paragraph in this Section 5.1 is grounds for DFCI to terminate this Agreement according to Section 8.2 or to convert this Agreement to a non-exclusive license agreement, at DFCI’s option.

5.2U.S. Manufacture. LICENSEE shall manufacture Licensed Products as required by 35 U.S.C. 204 and 37 C.F.R. 401 et. seq., as amended. LICENSEE shall also require any Affiliate(s) or Sublicensee(s) to comply with this U.S. manufacture requirement.

If LICENSEE provides compelling evidence to DFCI that domestic manufacture of a Licensed Product is not commercially feasible, at LICENSEE’s request, DFCI will cooperate with LICENSEE to seek a waiver from the United States government with respect to the United States manufacture requirement. If a waiver is to be sought, LICENSEE shall provide DFCI with the required information, prepare the initial paperwork necessary for applying for or obtaining the waiver and bear all costs associated with the waiver process. LICENSEE acknowledges that DFCI cannot guarantee that a waiver can or will be obtained.

Article 6 - Patent Preparation, Filing, Prosecution, and Maintenance

6.1Responsibility. Upon request of LICENSEE and at LICENSEE’s expense, DFCI shall provide (or shall instruct DFCI’s outside counsel to provide) to LICENSEE (or to an outside patent counsel of LICENSEE’s choice) copies of all correspondence and documentation related to the Patent Rights, including copies of all original files, and all official and internal correspondence related thereto, and any associated documents. LICENSEE, in its sole discretion, is responsible for preparing, filing, prosecuting, and maintaining all patent applications and patents covered by the Patent Rights, and is solely responsible for making strategic decisions regarding such Patent Rights and for paying all costs. DFCI shall not file any application that claims priority to, or benefit of, an application included in Patent Rights without LICENSEE’S prior written consent. DFCI will request that the law firms currently responsible for prosecution of the Patent Rights, transfer all file histories to LICENSEEE at the address provided in Section 6.3 below (attention Intellectual Property Department) within thirty (30) days of the Effective Date of this Agreement. DFCI shall execute Revocation Of Power Of Attorney With New Power Of Attorney And Change Of Correspondence Address documents for filing with the USPTO, in a timely manner not to exceed thirty (30) days, upon receipt of a request from FibroGen or its designated counsel. For purposes

of this Agreement, "prosecuting" or "prosecution" include all prosecution and any interference, reissue, or reexamination proceeding or opposition or other post-issuance or post-grant proceeding. LICENSEE shall provide DFCI with sufficient notification of LICENSEE’s intention to file U.S. CIP applications and/or foreign equivalent patent applications claiming priority to an application included in the Patent Rights. LICENSEE shall provide, or cause its agent to provide, copies of all correspondence between LICENSEE and/or LICENSEE’s counsel and the United States Patent and Trademark Office or the various foreign patent offices and shall give DFCI reasonable opportunity to advise LICENSEE or LICENSEE’s counsel on such matters.

6.2LICENSEE shall have the right to elect not to financially support the preparation, filing, prosecution, and maintenance of any patent application or patent included within Patent Rights. In such case, LICENSEE shall relinquish its rights to those patent applications or patents included within Patent Rights as provided in Section 6.5 below. Notwithstanding the foregoing, a strategic decision to discontinue the pursuit of a non-provisional patent application contained in the Patent Rights, shall not be construed as LICENSEE relinquishing its rights to the subject matter described therein if DFCI agrees in writing with such decision. LICENSEE’s strategic decision to discontinue the pursuit of a provisional patent application contained in the Patent Rights in favor of filing a new patent application (NPA) claiming the subject matter described in such provisional application shall not be construed as LICENSEE relinquishing its rights to the subject matter described therein if DFCI agrees in writing with such decision. If one or more inventors are added to the NPA as the result of the addition of new matter supplied by LICENSEE and said added inventor(s) are under an obligation to assign his or her rights in the NPA to LICENSEE, LICENSEE hereby assigns its rights in the NPA to DFCI and LICENSEE agrees to fully cooperate to perfect that title with the appropriate patent authorities. In no event will NPAs be filed which would result in the addition of inventor(s) who are not under an obligation to assign to LICENSEE.

6.3DFCI designates the following individual or department, or any designee thereof, to be available to consult with LICENSEE and to coordinate any reasonable response to a request from LICENSEE (see Section 6.4, infra), and to receive any patent-related correspondence:

6.4Cooperation. DFCI shall cooperate with LICENSEE in preparing, filing, prosecuting, and maintaining the patent applications and patents within Patent Rights. This cooperation is limited to making any DFCI personnel (including any named DFCI inventors or any other involved parties who are employed in the laboratories of Xx. Xxxxxx and\or Xx. Xxxxxxxxxx) available to answer questions, providing copies of any reasonably requested documents, including copies of pages in laboratory notebooks, manuscripts, etc., as may be necessary to provide required support and documentation for preparing, filing, prosecuting, and maintaining all patent applications and patents or for use in any post-issuance or post-grant procedure; and obtaining necessary signatures on documents, including, for example, any power of attorney, declaration, or assignment papers. DFCI will also direct any outside counsel involved in drafting, filing, prosecution, or maintenance of the patents and patent applications listed in Schedule 3 to cooperate fully with LICENSEE. LICENSEE will pay all associated costs, if any, incurred as a result of LICENSEE's requests for cooperation. DFCI shall provide prompt notice to LICENSEE of any matter that comes to its attention that may affect the patentability, validity, or enforceability of any patent application or patent within Patent Rights.

6.5Relinquishing Rights. If LICENSEE elects not to prepare, prosecute, and/or maintain a patent or patent application within Patent Rights in any country of the licensed Territory, LICENSEE shall give ninety (90) days advance written notice to DFCI; relinquish responsibility for prosecution of such patent or patent application; and surrender its license under such patent or patent application. However, if LICENSEE relinquishes rights to any patent or application within Patent Rights to which an interference proceeding or opposition has been declared or filed, the notice period is one hundred and eighty (180) days. If LICENSEE so relinquishes its rights, it will remain responsible for all patent-related expenses incurred by DFCI during the applicable notice period. Thereafter, LICENSEE will have no further obligation to pay any patent expenses for the patents or patent applications that it relinquished.

6.6Prosecution by DFCI. If LICENSEE relinquishes its rights within Patent Rights as described in Section 6.5, DFCI shall thereafter have the right, but not any obligation, to prosecute, obtain issuance of, and/or maintain such Patent Rights relinquished by LICENSEE in such country(ies) or region(s) at its own cost, and any such applications and resultant patents shall not be subject to this Agreement.

Article 7 - Patent Infringement and Enforcement

7.1Substantial Infringement. For the purposes of this Agreement, "Substantial Infringement" shall mean any infringement, of any of the Patent Rights, that LICENSEE deems material to its business. If at any time during the term of this Agreement, LICENSEE becomes aware of an apparent Substantial Infringement, LICENSEE will promptly notify DFCI of such infringement. In the event that LICENSEE chooses to take any action with respect to the Substantial Infringement, LICENSEE shall, upon the request of DFCI, provide DFCI with an explanation of LICENSEE's reasoning in choosing to take such action.

7.2Action by LICENSEE.

7.2.1

Procedure. LICENSEE shall have the first right, but not the obligation, to enforce the Patent Rights and to prosecute apparent Substantial Infringers, at its expense and in its own name, when it believes such action may be reasonably necessary and justified. Before LICENSEE files a lawsuit in a court of law with respect to the infringement, LICENSEE shall consider in good faith the views of DFCI,

particularly as they relate to the potential effects on the public interest. LICENSEE shall join DFCI as a party-plaintiff if such joinder is required by law (including, but not limited to, joinder of DFCI if deemed to be an indispensable party), at LICENSEE's expense. LICENSEE shall have the right to join Affiliates and Sublicensees into any such legal proceeding.

7.2.2

Timing. If LICENSEE notifies DFCI that it intends to prosecute the alleged Substantial Infringer, then LICENSEE has [ * ] months from the date of its notice to DFCI to either (a) cause the infringement to terminate or (b) file a lawsuit in a court of law against the infringer. If any such lawsuit is brought by LICENSEE in its own name it will be at LICENSEE’s expense and on its own behalf. LICENSEE has the right to join DFCI as a party-plaintiff if required by law, at LICENSEE’s expense.

7.2.3

Action at Request of DFCI. DFCI may request LICENSEE to take steps to protect the Patent Rights from an apparent Substantial Infringement. LICENSEE shall notify DFCI, within [ * ] months of receiving a written request from DFCI, of action it intends to take, if any, to compel termination of the alleged infringing action or to file a lawsuit in a court of law against the alleged infringer.

7.2.4

DFCI’s Right to Join. DFCI independently has the right to join any lawsuit brought by LICENSEE under this Section 7.2 and shall, in such case, fund a pro rata share of the cost of the legal proceeding from the date of joining. If DFCI elects to join as a party plaintiff pursuant to this Section 7.2.4, DFCI may jointly participate in the action with LICENSEE, but LICENSEE will have the right to designate lead counsel.

7.2.5

Settlement. In any legal proceeding initiated by LICENSEE, LICENSEE shall not enter into any settlement, consent judgment, or other voluntary final disposition in which a license to Patent Rights (or covenant not to xxx with respect to such Patent Rights) would be granted to the third party defendant pursuant to which DFCI’s future financial compensation would be significantly affected (such as future royalties as would be owed under a sublicense granted hereunder) or patent rights would be forfeited, without the consent of DFCI (which shall not be unreasonably withheld).

7.2.6

Reduction of Royalties. If LICENSEE initiates legal proceedings under this Section 7.2 in any country and DFCI does not independently join the proceeding, LICENSEE may deduct up to [ * ] of LICENSEE's documented costs, including reasonable attorney fees, from running royalties payable to DFCI from sales of Licensed Products covered by the patent(s)-in suit. However, LICENSEE may not reduce DFCI's royalty payments by more than [ * ] of the amount otherwise due under Section 3.1.5. If [ * ] of LICENSEE's costs and expenses exceeds the amount of royalties deducted by LICENSEE for any calendar year, LICENSEE may, to that extent, reduce the royalties due to DFCI in succeeding calendar quarters for so long as LICENSEE as the Substantial Infringement continues. However, LICENSEE may not reduce total royalties due to DFCI in a given calendar quarter by more than [ * ]. LICENSEE's right to reduce royalty payments to DFCI under this Section 7.2.6 applies only for so long as the Substantial Infringement continues.

7.3Action by DFCI

7.3.1

Procedure. If LICENSEE notifies DFCI that it does not intend to prosecute a Substantial Infringement, or if LICENSEE fails to cause the Substantial Infringement to terminate, or fails to file a lawsuit in a court of law to compel termination within [ * ] months of the date of its notice to DFCI pursuant to Section 7.1 or Section 7.2.3, above, then DFCI may initiate legal proceedings against the alleged infringer, at DFCI’s expense and on its own behalf according to the terms of this Section 7.3. Before DFCI commences any legal proceeding with respect to the infringement, DFCI shall consider in good faith the views of LICENSEE. DFCI has the right to join LICENSEE as a party-plaintiff, if required by law, at DFCI’s expense.

7.3.2

LICENSEE’s Right To Join. LICENSEE independently has the right to join any legal proceeding brought by DFCI under this Section 7.3 and shall, in such case, fund a pro rata share of the cost of the legal proceeding from the date of joining. If LICENSEE elects to join as a party plaintiff pursuant to this Section 7.3.2 or, LICENSEE may jointly participate in the action with DFCI, but DFCI will have the right to designate lead counsel.

7.3.3

Settlement. Regardless of whether LICENSEE is joined or joins any legal proceeding initiated by DFCI (as described in Section 7.3.2), no settlement, consent judgment, or other voluntary final disposition of such legal proceeding may be entered into without the consent of DFCI.

7.4Cooperation. If one party files a lawsuit in a court of law or brings any other action related to enforcement of the Patent Rights or otherwise related to the Patent Rights against a third party pursuant to this Article 7 or is prevented from filing such a lawsuit or bringing such an action against the third party due to lack of standing to xxx, the other party (and any Affiliates or Sublicensee of that party) shall cooperate with and supply all assistance reasonably requested by the party initiating the proceedings, at the initiating party's request and expense.

7.5Distribution of Amounts Paid by Third Parties. In any legal proceeding brought by DFCI under Section 7.3 and funded solely by DFCI, any damages or other amounts recovered as a result of the proceeding will be retained by DFCI. In any other legal proceeding, any damages or other amounts will be distributed as follows: The damages or other amounts will first be used to reimburse LICENSEE, it’s Affiliates or Sublicensees, and DFCI for litigation costs not paid from royalties and then to reimburse DFCI a sum equivalent to the total amount of royalties and minimum royalties deducted by LICENSEE under Section 7.2.6. The balance, if any, will be divided pro rata based on the relative contributions of the parties. It is expressly understood that any party not contributing to the funding of a proceeding will not share in any amounts recovered as a result of the proceeding.

7.6Declaratory Judgment Actions. In the event that any third party initiates a declaratory judgment action alleging the invalidity or unenforceability of the Patent Rights, or if any third party brings an infringement action against LICENSEE or its Affiliates or Sublicensees because of the exercise of the rights granted LICENSEE under this Agreement, then LICENSEE shall have the right to defend such action under its own control and at its own expense; provided, however, that DFCI shall (a) have option of joining as co-defendant if it chooses to do so; or (b) join as co-defendant if required by law; and (c) cooperate as necessary with LICENSEE in LICENSEE’s

defense. LICENSEE shall NOT enter into any settlement, consent judgment or other voluntary final disposition of any action under this Section 7.6 without the consent of DFCI, which consent shall not be unreasonably withheld unless the settlement includes any express or implied admission of liability or wrongdoing on DFCI's part, in which case DFCI's right to grant or deny consent is absolute and at its sole discretion. Any recovery shall be first applied to reimburse each party pro rata for any out-of pocket expenses it may have incurred with respect to defense of such action and the remainder shall be distributed as described in Section 7.5.

Article 8 - Term and Termination

However, any Sublicensee not in default under its sublicense may request conversion of the sublicense to a license directly between DFCI and Sublicensee. DFCI shall not unreasonably withhold its acceptance of such conversion under substantially the same financial terms and as those contained the sublicense, however, as a condition of DFCI’s acceptance, the Sublicensee must first agree to be bound by all of the non-financial provisions of this Agreement.

Article 9 - Indemnification, Defense and Insurance

9.1LICENSEE shall indemnify, defend and hold harmless DFCI and its trustees, officers, medical and professional staff, employees, and agents and their respective successors, heirs and assigns collectively, (the “DFCI Indemnitees”), against any claim, liability, damage, deficiency, obligation, cost, loss or expense (including reasonable attorneys' fees and expenses of litigation) incurred by or imposed upon the DFCI Indemnitees, or any one of them, in connection with any claims, suits, actions, demands or judgments (a) arising out of the design, production, manufacture, sale, use in commerce, lease, or promotion by LICENSEE or by a Sublicensee, Affiliate, or agent of LICENSEE, of any product, process or service relating to, or developed pursuant to, this

Agreement or (b) arising out of any other activities to be carried out pursuant to this Agreement. LICENSEE shall indemnify, defend by counsel reasonably acceptable to HHMI, and hold harmless HHMI and its trustees, officers, employees, and agents (collectively, “HHMI Indemnitees”) 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, including without limitation any cause of action relating to product liability. DFCI Indemnitees and HHMI Indemnitees may be referred to in this Agreement collectively as the “Indemnitees”). This Section 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 Indemnitee.

9.2LICENSEE shall, at its own expense, provide attorneys reasonably acceptable to DFCI to defend against any actions brought or filed against any party indemnified hereunder with respect to the subject of indemnity contained herein, whether or not such actions are rightfully brought.

9.3If any such action is commenced or claim made or threatened against DFCI or other Indemnitees as to which LICENSEE is obligated to indemnify it (them) or hold it (them) harmless, DFCI or the other Indemnitees shall promptly notify LICENSEE of such event. In the case of any HHMI Indemnitee, notice shall be given reasonably promptly following actual receipt of written notice of the action or claim by an officer or attorney of HHMI. LICENSEE shall assume the defense of, and may settle, that part of any such claim or action commenced or made against DFCI (or other Indemnitees) which relates to LICENSEE’s indemnification and LICENSEE may take such other steps as may be necessary to protect it. LICENSEE will not be liable to DFCI or other Indemnitees on account of any settlement of any such claim or litigation affected without LICENSEE’s consent. The right of LICENSEE to assume the defense of any action is limited to that part of the action commenced against DFCI and/or Indemnitees that relates to LICENSEE’s obligation of indemnification and holding harmless. Notwithstanding the foregoing, LICENSEE shall not 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.

9.4LICENSEE shall require any Affiliates or Sublicensee(s) to indemnify, hold harmless and defend DFCI and HHMI under the same terms set forth in Sections 9.1 – 9.3 and Section 9.5.

9.5HHMI is not a party to this Agreement and has no liability to any LICENSEE, sublicensee, or user of anything covered by this Agreement, but HHMI is an intended third-party beneficiary of this Agreement and certain of its provisions are for the benefit of HHMI and are enforceable by HHMI in its own name.

Insurance.

9.6At such time as any product, process or service relating to, or developed pursuant to, this Agreement is being commercially distributed or sold (other than for the purpose of obtaining regulatory approvals) by LICENSEE or by a Sublicensee, Affiliate or agent of LICENSEE, LICENSEE shall, at its sole cost and expense, procure and maintain policies of commercial general liability insurance in amounts not less than $2,000,000 per incident and $2,000,000 annual aggregate and naming the Indemnitees as additional insureds. Such commercial general liability

insurance must provide (a) product liability coverage and (b) contractual liability coverage for LICENSEE's indemnification under Sections 9.1 through 9.5 of this Agreement. If LICENSEE elects to self‑insure all or part of the limits described above (including deductibles or retentions which are in excess of $250,000 annual aggregate), such self‑insurance program must be acceptable to the DFCI and the DFCI's associated Risk Management Foundation. The minimum amounts of insurance coverage required under these provisions may not be construed to create a limit of LICENSEE's liability with respect to its indemnification obligation under Sections 9.1 through 9.5 of this Agreement.

9.7LICENSEE or its insurance carrier shall provide DFCI with written evidence of such insurance upon request of DFCI. LICENSEE or its insurance carrier shall promptly notify DFCI, in the event that LICENSEE receives notice of cancellation, non-renewal or other material change in such insurance. LICENSEE acknowledges its obligation to maintain insurance coverage as described in Section 9.6. As such, in the event that LICENSEE receives notice of cancellation, non-renewal or other material change of such insurance, LICENSEE must elect to either (i) obtain replacement insurance providing comparable coverage or, (ii) implement a self-insurance program acceptable to DFCI and DFCI's associated Risk Management Foundation. LICENSEE shall provide written notice and proof that it has either obtained replacement insurance or implemented self-insurance program to DFCI at least fifteen (15) days prior to the cancellation or material change in such insurance coverage. Notwithstanding the foregoing, in the event that LICENSEE elects (ii) above, LICENSEE must provide DFCI and DFCI's associated Risk Management Foundation with sufficient information to allow a review and acceptance of LICENSEE’s self-insurance program prior to aforementioned fifteen (15) day period.

If LICENSEE does not notify DFCI and provide proof that it has either obtained replacement insurance coverage or implemented a self insurance program acceptable to DFCI at least fifteen (15) days prior to the effective date of cancellation or material change in such insurance coverage, DFCI has the right to terminate this Agreement effective the date the insurance coverage is cancelled, not renewed or otherwise materially changed without additional waiting periods. In such event, DFCI agrees to provide written notice within twenty-four (24) hours pursuant to Article 11 (“Notices”) to LICENSEE that this Agreement is terminated under Article 8.2.

9.8LICENSEE shall maintain such comprehensive general liability insurance beyond the expiration or termination of this Agreement during (a) the period that any product, process, or service, relating to, or developed pursuant to, this Agreement is being commercially distributed or sold (other than for the purpose of obtaining regulatory approvals) by LICENSEE or by a Sublicensee, Affiliate or agent of LICENSEE.

9.9LICENSEE shall require any Affiliates or Sublicensee(s) to maintain insurance in favor of DFCI and the Indemnitees under the same terms set forth in Sections 9.6 – 9.8.
