If any Taxes are required by Applicable Law to be withheld on amounts payable to DFCI under this Agreement, Licensee will pay to DFCI an additional amount as is necessary to ensure that the amount actually received by DFCI is equal to the amount of payment that would have been made if no such Taxes had applied. If Taxes are imposed on a

payment to DFCI under Applicable Law, Licensee will, to the extent such is available, promptly provide evidence that Licensee has paid such Taxes to the proper taxing authority.

4.4    Currency 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 transfer of such other currency as quoted by the Wall Street Journal on the last business day of the applicable accounting period in the case of any payment payable with respect to a specified accounting period or, in the case of any other payment, the last business day before the date the payment is due.

4.5    Interest. 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 III and such interest payment will be due immediately but in no event later than the payment of the overdue amount to DFCI. The interest will be calculated at the annual rate of the sum of (a) two percent (2%) 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; provided that the annual rate may not exceed the maximum legal interest rate permitted by Applicable Law. The payment of interest as required by this Section 4.5 does not foreclose or in any way limit DFCI from exercising any other rights or remedies it has as a consequence of the lateness of any payment.

5.1    Due Diligence.

a.General Obligations. Licensee shall use Commercially Reasonable Efforts to bring one or more Licensed Products or Licensed Processes to the marketplace as soon as reasonably practicable. After commercialization, Licensee shall continue Commercially Reasonable Efforts to keep Licensed Products and Licensed Processes available to the public.

b.Development and Commercialization Reports. On or before each anniversary of the Effective Date, Licensee shall provide to DFCI a written report describing the efforts by Licensee, or any Affiliates or Sublicensees, to bring one or more Licensed Products or Licensed Processes to the marketplace. The report must be in sufficient detail to permit DFCI to monitor Licensee’s compliance with the diligence provisions and requirements of this Agreement. Licensee shall include at least the following in these reports: (a) a summary of Licensee’s progress toward meeting the goals and objectives that had been established for the previous Calendar Year; (b) a summary of Licensee’s goals and objectives for the ensuing Calendar Year for developing and commercializing Patent Rights, including an identification of additional Licensed Products or Licensed Processes that Licensee intends to develop, if any and, if after the date of First Commercial Sale in any country, a summary of the activities of Licensee, and any Affiliates and Sublicensees, directed toward promoting the sale of Licensed Products in the Territory.

c.Failure to Perform. Licensee’s failure to satisfy any diligence obligations set forth in Section 5.1(a) shall give rise to DFCI’s ability to terminate this Agreement pursuant to Section 8.2(c).

d.Decision Not to Further Exploit. If at any time during the Term, Licensee decides not to Exploit or further Exploit a particular Licensed Product or Licensed Process, either by itself, with an Affiliate or through sublicensing, it shall promptly inform DFCI in writing. Unless within sixty (60) days of such notice to DFCI, Licensee establishes to DFCI’s satisfaction that the particular Licensed Product or Licensed Process that will no longer be Exploited is directly comparable to another Licensed Product or Licensed Process that Licensee is diligently developing or commercializing pursuant to this Agreement, DFCI has the right to terminate this Agreement by immediate written notice insofar as it applies to the particular Licensed Product or Licensed Process by providing written notice to Licensee. For clarity, any decision by Licensee to not develop or to not commercialize a Licensed Product or Licensed Process shall be a decision not to “Exploit” such Licensed Process or Licensed Product under this Section 5.1(d). In no event shall

this Section 5.1(d) limit or eliminate, in any way, DFCI’s other rights and remedies under this Agreement and under Applicable Law, including DFCI’s right to terminate this Agreement as described in Section 5.1(c).

This section is intentionally left blank.

5.3    Other Government Laws. Licensee shall comply with, and ensure that its Affiliates and Sublicensees comply with, all Applicable Laws that relate to Licensed Processes or Licensed Products. These include but are not limited to FDA statutes and regulations, the Export Administration Act of 1979, as amended, codified in 50 App. U.S.C. 2041 et seq. and the regulations promulgated thereunder or other applicable export statutes or regulations.

5.4    This section is intentionally left blank.

5.5    Publicity; Use of Name. Licensee, its Affiliates and Sublicensees are not permitted to use the names of DFCI, the Inventor, its related entities or its employees, or any adaptations thereof, in any advertising, promotional or sales literature, or in any securities report required by the Securities and Exchange Commission (except as required by law), without the prior written consent of DFCI in each case. However, Licensee may (a) refer to publications in the scientific literature by employees of DFCI or (b) state that a license from DFCI has been granted as provided in this Agreement.

5.6    Confidentiality. All Confidential Information that is provided by one Party (the “disclosing Party”) to the other Party (the “receiving Party”) hereunder shall be maintained in confidence by the receiving Party, and shall not be disclosed to any Third Party or used for any purpose other than performance of its obligations and exercise of its rights under this Agreement. The Parties agree that disclosure by Licensee of development plan information constituting Exhibit B of this Agreement shall be considered Confidential Information despite such disclosure having occurred prior to the Effective Date hereof, and such information shall be subject to this Section 5.6. For the avoidance of doubt, Confidential Information of DFCI includes analyses or opinions of Third Party intellectual property that may be provided to Licensee by DFCI’s external counsel and any information in connection with patent preparation, filing, prosecution and maintenance under the terms of ARTICLE VI, and Confidential Information of Licensee includes reports submitted to DFCI pursuant to Section 5.1(b). Each Party agrees, during the Term and for five (5) years thereafter, to employ all reasonable efforts to keep the Confidential Information secret and confidential, such efforts to be no less than the degree of care employed by such Party to preserve and safeguard its own confidential information. The Confidential Information shall not be disclosed or revealed to anyone except employees or agents of or consultants to receiving Party who have a need to know the information and who have entered into a secrecy agreement with Licensee under which such employees, agents, or consultants are required to maintain as confidential the Confidential Information and such employees, agents, or consultants shall be advised by Licensee of the confidential nature of the Confidential Information and that the Confidential Information shall be treated accordingly. The receiving Party’s obligations under this Section shall not extend to any part of the information:

a.that can be demonstrated to have been in the public domain prior to the date of the disclosure;

b.that can be demonstrated, from written records, to have been in the receiving Party’s possession prior to the disclosure;

c.that becomes part of the public domain or publicly known by publication or otherwise, not due to any act or omission of the receiving Party, its employees, agents or consultants; or

d.that is demonstrated from written records to have been independently developed by or for the receiving Party without reference to the Confidential Information.

Notwithstanding anything to the contrary in this Agreement, the receiving Party may disclose the Confidential Information in order to comply with Applicable Law or a valid court order, in each case in connection with the receiving Party’s rights and obligations pursuant to this Agreement. Notwithstanding

the foregoing, in the event the receiving Party is required to make a disclosure of Confidential Information pursuant to the preceding sentence, it will, (x) to the extent permissible under Applicable Law, give reasonable advance notice to the disclosing Party of such disclosure to provide an opportunity for the disclosing Party to challenge or limit the disclosure obligations, (y) use reasonable efforts to secure confidential treatment of such Confidential Information and (z) use reasonable efforts to avoid disclosure of Confidential Information.

5.7    Terms of the Agreement. Each Party agrees not to, and to cause its Affiliates not to, disclose to any Third Party the terms of this Agreement without the prior written consent of the other Party hereto, which consent shall not be withheld unreasonably, except each Party and its Affiliates may disclose the terms of this Agreement without such consent: (a) to advisors (including financial advisors, legal advisors and accountants), actual or potential acquisition partners or private investors, licensees and other financial parties on a reasonable need to know basis, in each case under appropriate confidentiality provisions substantially equivalent to those in this Agreement; or (b) to the extent necessary to comply with Applicable Law and court orders (including securities laws or regulations and the applicable rules of any public stock exchange); provided that in the case of clause (b), the disclosing Party or its Affiliate shall promptly notify the other Party and (other than in the case where such disclosure is necessary, in the reasonable opinion of the disclosing Party’s legal counsel, to comply with securities laws or regulations) allow the other Party a reasonable opportunity to intervene to protect the confidentiality of the information and oppose such disclosure and, to the extent allowable by law, to seek limitations on the portion of the Agreement that is required to be disclosed. Where such disclosure is necessary, in the reasonable opinion of the disclosing Party’s legal counsel, to comply with securities laws or regulations, the disclosing Party shall allow the other Party a reasonable opportunity to review such proposed disclosure and suggest portions of such disclosure for confidential treatment, which suggestions the disclosing Party shall reasonably consider. Notwithstanding any other provisions of this Agreement: (x) the Parties may provide information about this Agreement and amounts paid as part of routinely prepared summary documents that do not disclose any terms that were not disclosed in a mutually agreed press release; (y) the Parties may make factual statements regarding the existence, nature, and type of this Agreement, provided that such statements do not disclose specific terms hereof; and (z) DFCI may report consideration to institutions, inventors or others to whom royalties are payable based on activities performed hereunder and to the government as necessary or required.

a.Notwithstanding anything to the contrary in this Agreement, DFCI retains the right to publish, present and otherwise publicly disseminate any results or other information stemming from the rights retained as set forth in Section 2.4.

6.1    Responsibility. Subject to Section 3.1(b), DFCI, in its sole discretion, is responsible for preparing, filing, prosecuting and maintaining the patent applications and patents included within Patent Rights, in consultation with Licensee. For purposes of this Agreement, patent “prosecution” and “prosecuting” includes ex parte prosecution, interference proceedings, reissues, reexaminations, oppositions and all proceedings before a patent office in the Territory, including inter partes review, appeals and post grant review proceedings, and any judicial or other appeals of the foregoing. DFCI shall provide, or cause its agent to provide, to Licensee copies of relevant material correspondence between DFCI and the United States Patent Office or the various foreign patent offices with respect to the filing, prosecution and maintenance of Patent Rights.

6.2    Relinquishing Rights. Licensee may surrender its licenses under any of the patents or patent applications within Patent Rights in any country of the Territory by giving ninety (90) days advance written notice to DFCI. However, if Licensee is surrendering any patent or application within Patent Rights on which an inter partes review, post grant review proceeding, interference proceeding, other opposition or any appeal thereof has been declared or filed, the notice period is one hundred and eighty (180) days. If Licensee so surrenders its rights, it will remain responsible for all patent-related expenses incurred by DFCI before or 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 surrendered. Notwithstanding the foregoing, if such surrender results in termination of all rights under this Agreement, then such surrender shall be deemed a termination of this Agreement in its entirety and the termination notice provision in Section 8.3 shall apply.

7.1    Responsibility. Subject to the rights of co-applicants or co-owners of any Patent Rights, DFCI, in its sole discretion, is responsible for preparing, filing, prosecuting, maintaining, enforcing and defending the patent applications and patents included within Patent Rights. For purposes of this Agreement, patent “prosecution” and “prosecuting” includes ex parte prosecution, interference proceedings, reissues, reexaminations, oppositions and all proceedings before a patent office in the Territory, including inter partes review, appeals and post grant review proceedings, and any judicial or other appeals of the foregoing.

7.2    Cooperation. Licensee shall cooperate with DFCI in preparing, filing, prosecuting, maintaining, extending, enforcing and defending the patent applications and patents within Patent Rights, as applicable. Licensee shall provide prompt notice to DFCI of any matter that comes to its attention that may affect the patentability, validity, enforceability, or infringement, or support any extension (including patent term extension pursuant to 35 U.S.C. § 156 and comparable laws and supplementary protection certificates) of any patent application or patent within Patent Rights.

If, at any time during the term of this Agreement, Licensee becomes aware of any infringement of or challenge to the Patent Rights, it will promptly notify DFCI.

7.3    Paragraph IV Type Notices. Without limiting any other obligation under this Agreement, each Party will immediately (but in no event more than five (5) days after awareness) give written notice to the other of any certification of which it becomes aware filed pursuant to any statutory or regulatory requirement in any country in the Territory similar to 21 U.S.C. § 355(b)(2)(A)(iv) or § 355(j)(2)(A)(vii)(IV) (or any amendment or successor statute thereto) claiming that any Patent Right Covering any Licensed Product or License Process is invalid or that infringement will not arise from the development, manufacture, use or commercialization in the Territory of such Licensed Product or Licensed Process by a Third Party. Licensee shall promptly provide to DFCI copies of all correspondence by or to Licensee or its Affiliates related to such certification.

8.1    Term. The term of this Agreement shall commence on the Effective Date and remain in effect until, unless terminated earlier under the provisions of this Agreement, the later of the (a) expiration date of the last to expire of patents within Patent Rights and (b) the expiration of all of Licensee’s payment obligations to DFCI pursuant to this Agreement (such time period, the “Term”).

c.Licensee fails to comply with any of the due diligence obligation provided for in Sections 5.1(a) through 5.1(c) or Section 5.1(e) and Licensee has not cured the default by satisfying such obligation within sixty (60) days of receiving written notice of default from DFCI.

d.Licensee defaults in its obligations to procure and maintain insurance under Section 9.2.

e.An officer of the Licensee, its Affiliate or Sublicensee is convicted of a felony relating to the manufacture, use, sale or importation of one or more Licensed Products.

e.Return of Confidential Information. Within sixty (60) days of the effective date of any termination of this Agreement (but not the expiration of this Agreement in accordance with the terms hereof), each Party shall, at the disclosing Party’s option, either return or destroy all materials relating to or containing Confidential Information, except to the extent such Confidential Information is maintained by the receiving Party as part of a permitted disclosure under Section 5.7. Notwithstanding the foregoing, (i) the receiving Party will be permitted to retain one copy of such materials for archival and legal compliance purposes and (ii) the receiving Party will not be required to delete or destroy any electronic back-up tapes or other electronic back-up files that have been created solely by the automatic or routine archiving and back-up procedures of the receiving Party, to the extent created and retained in a manner consistent with its or their standard archiving and back-up procedures.

f.Sublicenses. Any Sublicenses will terminate contemporaneously with this Agreement. However, any Sublicensee not in default under its Sublicense may request conversion of the Sublicense to a license directly between DFCI and Sublicensee on or before the thirtieth day following termination of this Agreement. DFCI shall not unreasonably withhold its acceptance of such conversion, however, as a condition of DFCI’s acceptance, the Sublicensee must first agree to be bound by all of the provisions of this Agreement.

a.Licensee 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 “Indemnitees” and each, an “Indemnitee”) against any liability, damage, loss or expense (including attorneys’ fees and expenses of litigation) incurred by or imposed upon the Indemnitees, or any one of them, in connection with any claims, suits, actions, demands or judgments arising from or occurring as a result of: (i) the research, development, design, production, manufacture, sale, use in commerce, lease, promotion or other Exploitation of any product, process or service relating to, or developed pursuant to, this Agreement (including any Licensed Process or Licensed Product) by Licensee or by a Sublicensee, Affiliate or agent of Licensee, (ii) a breach of this Agreement by Licensee or (iii) any activities carried out pursuant to this Agreement or the exercise of any rights granted under this Agreement by Licensee, its Affiliates, Sublicensees or permitted subcontractors.

c.If 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; provided that any failure to do so shall not affect the Indemnitee’s right to indemnification hereunder, except to the extent that such failure or delay impairs the Licensee’s ability to defend or contest any such claim. 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 Licensee shall assume the defense of any suit or claim for which indemnification is sought under this Section 9.1. Licensee shall, at its own expense, provide attorneys reasonably

acceptable to DFCI 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 keep DFCI informed of the progress of the indemnified claim. DFCI may participate in the defense thereof at its sole cost and expense. Licensee may not enter into any settlement, consent judgment, or other voluntary final disposition of any claim that has an adverse effect on the rights of any Indemnitee(s) hereunder or admits any wrongdoing or fault by any Indemnitee(s) or imposes on any Indemnitee(s) any payment or other liability or obligation, without the prior written consent of DFCI.

a.At 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 $1,000,000 per incident and $2,000,000 annual aggregate and products liability insurance in amounts not less than $5,000,000 per incident and $5,000,000 annual aggregate, . Such commercial general liability insurance must provide contractual liability coverage for Licensee’s indemnification under Section 9.1 of this Agreement. If Licensee elects to selfinsure all or part of the limits described above (including deductibles or retentions which are in excess of $250,000 annual aggregate), such selfinsurance 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 Section 9.1 of this Agreement.

b.Licensee shall provide DFCI with written evidence of such insurance upon request of DFCI. Licensee shall provide DFCI with written notice at least fifteen (15) days prior to the cancellation, nonrenewal or material change in such insurance; if Licensee does not obtain replacement insurance providing comparable coverage within such fifteen (15) day period, DFCI has the right to terminate this Agreement effective at the end of such fifteen (15) day period without any notice or additional waiting periods.
