2.2.1.

Development Plan.  The Development of Collaboration Compounds and Licensed Products shall be governed by the Development Plan, and the Parties may not Develop any Collaboration Compound or Licensed Product other than in accordance with the Development Plan or as set forth in Section 2.2.3(c) or Section 2.3. Each Party shall use Commercially Reasonable Efforts to conduct all their Development activities relating to Licensed Products in accordance with the Development Plan. Summit shall prepare the initial draft of the initial

Development Plan for review and approval by the JSC. The JSC shall be responsible for approving the initial Development Plan. Unless otherwise approved by the JSC, the Development Plan shall include in reasonable detail (a) all Development activities reasonably anticipated to be undertaken by each Party, (b) the endpoints for all Clinical Studies contemplated by such plan, (c) which Clinical Study is intended to be a Pivotal Clinical Study, (d) all regulatory activities and interactions anticipated to be conducted by each Party in support of Regulatory Approval of each Licensed Product, including all planned regulatory filings to be submitted in connection with such approvals, (e) a good faith non-binding estimate of the dates on which the Parties expect to achieve each milestone event set forth in TABLE 8.2.1, and, if applicable, TABLE 8.2.2 and TABLE 8.2.3 and (f) a budget for all Development Costs. The JSC shall approve the initial Development Plan within ninety (90) days after the Effective Date in accordance with Section 5.3.1(a), and once the JSC approves such initial Development Plan, it will be attached to this Agreement as Exhibit A.

2.2.2.

Amendments.  Following the JSC’s approval of the initial Development Plan, it shall review the Development Plan not less frequently than annually and shall develop detailed and specific Development Plan updates, each of which shall update and include annual Development budgets for the following Calendar Year until the completion of Licensed Product Development activities.  The Parties may also develop and submit to the JSC from time to time other proposed substantive amendments to the Development Plan. In addition, upon approval of any Additional Study by the JSC pursuant to Section 5.3.1(d) and the Non-Proposing Party’s agreement to co-fund such study, the JSC will amend the Development Plan to include such Additional Study. Further, upon designation of such Next Generation Collaboration Compound as a Development Candidate pursuant to Section 5.3.1(i), the Parties will develop and submit to the JSC an amendment to the Development Plan that includes the proposed Development activities with respect to such Next Generation Collaboration Compound. The JSC shall review such proposed amendments and may approve such proposed amendments or any other proposed amendments that the JSC may consider from time to time in its discretion and, upon such approval by the JSC, the Development Plan shall be amended accordingly. Amendments and updates to the Development Plan, including any budgets contained in the Development Plan, shall not be effective without the approval of the JSC.

2.2.3.

Development Costs.

(a)

Responsibility for Costs.  

(i)

During the period beginning on the Effective Date and ending on December 31, 2017, subject to Section 2.2.3(a)(iii), Summit shall be solely responsible for all Development Costs; provided, however, that, if Sarepta incurs Development Costs in excess of one hundred ten percent (110%) of the Development Costs budgeted for activities assigned to Sarepta in the budget of the

then-current version of the Development Plan, then Sarepta shall be solely responsible for such excess costs unless Summit agrees in writing to assume them.

(ii)

Beginning on January 1, 2018, subject to Section 2.2.3(a)(iii) and Section 2.2.3(c), Summit shall pay fifty-five percent (55%) and Sarepta shall pay forty-five percent (45%) of all Development Costs that are within one hundred ten percent (110%) of the Development Costs budgeted for activities included in the budget of the then-current version of the Development Plan.  Any Development Costs in excess of one hundred ten percent (110%) of such budgeted Development Costs shall be borne solely by the Party incurring such costs unless such Party has received the other Party’s written approval to share such excess costs.  

(iii)

If Sarepta exercises the Territory Expansion Option pursuant to Section 4.2, then, from and after the Territory Expansion Option Exercise Date, Sarepta shall be solely responsible for all Development Costs specifically related to the Option Territory;  provided, however, that, if Summit incurs Development Costs specifically related to the Option Territory in excess of one hundred ten percent (110%) of the Development Costs budgeted for activities assigned to Summit in the budget of the then-current version of the Development Plan, then Summit shall be solely responsible for such excess costs unless Sarepta agrees in writing to assume them.

(iv)

In each case contemplated by Sections 2.2.3(a)(i) – 2.2.3(a)(iii), Development Costs shall initially be borne by the Party incurring the cost or expense, subject to reimbursement as provided in Section 2.2.3(b).  Each Party shall calculate and maintain records of Development Costs incurred by it in accordance with procedures to be established by the JSC pursuant to Section 5.3.1(e).

(b)

Development Cost Reports. Within fifteen (15) business days following the beginning of the last month of each Calendar Quarter, each Party shall prepare and deliver to the JSC a quarterly report detailing its and its Affiliates’ Development Costs (i) incurred during the first two (2) months of such Calendar Quarter, (ii) estimated to be incurred during the last month of such Calendar Quarter and (iii) actually incurred in the last month of the immediately preceding Calendar Quarter, in each case, ((i)-(iii)), that are required to be shared pursuant to this Section 2.2.3.  Each Party shall submit any supporting information or clarifications reasonably requested by the other Party related to such Development Costs included in such Party’s report within ten (10) business days after the other Party’s receipt of such request.  The Parties, with the assistance

of the JSC, shall conduct a reconciliation of Development Costs for the subject Calendar Quarter within ten (10) business days after receipt of all such supporting information, and an invoice shall be issued to the Party (if any) that has not paid for its full share of the Development Costs for such Calendar Quarter.  Such reconciliation shall balance the actual amount of Development Costs incurred during the last month of the immediately preceding Calendar Quarter (to correct for any differences between the estimates and actual amount of such costs) together with the amounts incurred during the first two (2) months of such Calendar Quarter and those estimated to be incurred during the last month of such Calendar Quarter.  The paying Party shall pay all amounts payable under any such invoice within forty-five (45) days after its receipt of such invoice.

(c)

(d)

Development Buy-In. At any time prior to the completion of an Additional Study that the Non-Proposing Party declined previously to co-fund, the Non-Proposing Party will have the right to elect by written notice to the Proposing Party to include in the shared Development Costs the costs of such Additional Study (the “Development Buy-In”).  In such case, (i) the Parties shall share any Development Costs from the day of such notice onward incurred by the Proposing Party to conduct such Additional Study after the Development Buy-In in accordance with Section 2.2.3 and (ii) the Non-Proposing Party shall reimburse the Proposing Party an amount equal to [**] of the costs incurred by the Proposing Party in conducting such Additional Study prior to the day of such notice. Upon any such Development Buy-In, the Parties shall have the rights with respect to such Clinical Studies or studies and the data arising therefrom as set forth in Sections 2.5.3 and 3.2.  If the Non-Proposing Party elects a Development Buy-In, then it shall pay to the Proposing Party the amount set forth in the foregoing clause (ii) within forty-five (45) days after the Non-Proposing Party notifies the Proposing Party in writing that the Non-Proposing Party is exercising its right to effect the Development Buy-In pursuant to this Section 2.2.3(d).

(e)

Post-Development Buy-In. If the Non-Proposing Party wishes to exercise a buy-in with respect to an Additional Study after the completion of such Additional Study (a “Post-Development Buy-In”), then the Non-Proposing Party shall notify the Proposing Party thereof in writing and pay to the Proposing Party for such Additional Study a lump sum payment equal to [**] of the costs that the Proposing Party incurred in conducting such Additional Study. Upon any such Post-Development Buy-In, the Parties shall have the rights with respect to such Clinical Studies or studies and the data arising therefrom as set forth in Sections 2.5.3 and 3.2.  If the Non-Proposing Party elects a Post-Development

8.4.6.

Royalty Anti-Stacking.  Subject to Section 8.4.7, if Sarepta (a) determines in good faith that, in order to avoid infringement of any Third Party’s Patent Rights not licensed to Sarepta hereunder, it is reasonably necessary to obtain a license after the Effective Date from a Third Party under Patent Rights owned or licensable by such Third Party Covering such Licensed Product (but excluding any such Patent Rights (i) to the extent Covering a use of such Licensed Product that is not indicated in a Regulatory Approval for such Licensed Product in such

country or (ii) owned or licensable by a contract manufacturing organization engaged by Sarepta) in order to Manufacture or Commercialize a Licensed Product in the Field in a country in the Sarepta Territory and to pay a royalty under such license (including in connection with the settlement of a patent infringement claim) or (b) becomes subject to a final court or other binding order or ruling requiring the payment of a royalty or damages to a Third Party patent holder in respect of the Manufacture or Commercialization of a Licensed Product in the Field in a country in the Sarepta Territory, then, on a country-by-country basis, in each case, ((a) and (b)), the amount of Sarepta’s royalty payments under Section 8.4.1 with respect to Net Sales for such Licensed Product in such country in any Calendar Quarter shall be reduced by [**] of the payments actually paid by Sarepta to such Third Party in consideration for such license that are reasonably and appropriately allocable to such Licensed Product in the Field in such country during such Calendar Quarter.

8.4.7.

Royalty Floor.  Notwithstanding the foregoing provisions of this Section 8.4, in no event during the applicable Royalty Term for a Licensed Product in a country of the Sarepta Territory shall the royalties payable to Summit hereunder for such Licensed Product in such country for any Calendar Quarter be reduced pursuant to Sections 8.4.4, 8.4.5 and 8.4.6 to less than [**] of the royalties payable pursuant to Section 8.4.1 as to such Licensed Product in such country for such Calendar Quarter.

8.4.8.

During the Term, following the First Commercial Sale of a Licensed Product in the Sarepta Territory, Sarepta shall furnish to Summit a written report within forty-five (45) days after the end of each Calendar Quarter showing, on a Licensed Product-by-Licensed Product and country-by-country basis, the gross sales of each Licensed Product in each country of the Sarepta Territory, deductions from gross sales (itemized by deduction category) for each Licensed Product for each country of the Sarepta Territory included in the calculation of Net Sales, the Net Sales in each country of the Sarepta Territory of Licensed Product during the reporting period and the royalties payable under this Agreement.

8.5.

Audits.

8.5.1.

Records; Inspections.  Each Party shall keep complete and accurate records of the items underlying Development Costs, Declined NG Candidate Development Costs, Net Sales, Cost of Goods, royalties, milestones, other license fees and other payments under this Agreement.  Upon the written request of a Party and

not more than once in each Calendar Year, the other Party and its Related Parties shall permit an independent certified public accounting firm of internationally-recognized standing selected by the requesting Party and reasonably acceptable to the other Party, at the requesting Party’s expense except as set forth below, to have access during normal business hours to such of the records of the other Party as may be reasonably necessary to verify the accuracy of the payments and reports hereunder for any year ending not more than three (3) years prior to the date of such request for the sole purpose of verifying the basis and accuracy of payments made under this Agreement.

8.5.2.

Discrepancies.  If such accounting firm identifies a discrepancy made during such period, then the appropriate Party shall pay the other Party the amount of the discrepancy (together with, in the case of any underpayments, late-payment interest in accordance with Section 8.7) within fifteen (15) days after the date the requesting Party delivers to the other Party such accounting firm’s written report so concluding, or as otherwise agreed by the Parties in writing.  The fees charged by such accounting firm shall be paid by the requesting Party, unless such discrepancy represents an underpayment by the other Party of at least [**] of the total amounts due hereunder in the audited period, in which case such fees shall be paid by the other Party.

8.5.3.

Compliance with In-Licenses.  Each Party shall comply with all applicable audit requirements in the In-Licenses and shall include in each sublicense granted by it pursuant to this Agreement a provision requiring the Sublicensee to make reports to the Party that is party to such In-License, to keep and maintain records of sales made pursuant to such sublicense and to grant access to such records by the independent accountant of the Party that is party to such In-License to the same extent required of a Party under this Agreement.

8.5.4.

Audit Term.  Unless an audit for such year has been commenced prior to and is ongoing upon the third (3^rd) anniversary of the end of such year, the calculation of payments payable with respect to such year shall be binding and conclusive upon both Parties, and each Party and its Related Parties shall be released from any further liability or accountability with respect to such royalties or expense reimbursement for such year.

8.5.5.

Confidential Treatment.  Each Party shall treat all financial information subject to review under this Section 8.5 or under any sublicense agreement in accordance with the confidentiality and non-use provisions of this Agreement, and shall cause its accounting firm to enter into a written confidentiality agreement with the other Party or its Related Parties obligating it to retain all such information in confidence pursuant to such confidentiality agreement, which terms shall be no less stringent than the provisions of Section 9.

8.6.

Payment Exchange Rate.  Each payment to be made to Summit under this Agreement shall be made in such currency and to such bank account in the United Kingdom as may be designated in writing by Summit from time to time. All payments to be made under this

Agreement to Sarepta shall be made in United States dollars and shall be paid by bank wire transfer in immediately available funds to such bank account in the United States as may be designated in writing by Sarepta from time to time. If, in a given Calendar Quarter, either Party is required to convert between currencies in order to make a payment in accordance with this Section 8.6, then such Party shall make such conversion using the average rate of exchange for such Calendar Quarter utilized by such Party in its worldwide accounting system and calculated in accordance with GAAP.

8.7.

Late Payments.  Any amount owed by a Party to the other Party under this Agreement that is not paid on or before the date such payment is due shall bear interest at a rate per annum equal to the lesser of (a) the then-current one (1) month London Inter-Bank Offering Rate for US Dollars, as quoted on the British Banker’s Association’s website currently located at www.bba.org.uk (or such other source as may be mutually agreed by the Parties) plus [**] per annum or (b) the highest rate permitted by Law, calculated on the number of days such payments are paid after such payments are due and compounded monthly.

8.8.

Blocked Payments.  If, by reason of applicable Laws in any jurisdiction in a Party’s Territory, it becomes impossible or illegal for a Party to transfer milestone payments, royalties or other payments under this Agreement to the other Party, then the payor shall promptly notify the payee. During any such period described above, the payor shall deposit such payments in local currency in the relevant jurisdiction to the credit of the payee in a recognized banking institution designated by the payee or, if none is designated by the payee within a period of ninety (90) days, in a recognized banking institution selected by the payor and identified in a written notice given to the payee.

8.9.

Taxes.  If a timely and appropriately completed and executed Internal Revenue Service Form W-9 is provided by the receiving Party to the paying Party, then the Parties acknowledge and agree that no United States tax withholding shall be applied with respect to the payments due under this Agreement. Each Party shall use reasonable efforts to minimize tax withholding on payments made to the other Party. Notwithstanding such efforts, if such Party concludes that tax withholdings under the Laws of any country are required with respect to payments to the other Party, then such Party shall first notify the other Party and provide such Party with twenty (20) days to determine whether there are actions such receiving Party can undertake to avoid such withholding. During this notice period, the paying Party shall refrain from making such payment until the receiving Party instructs the paying Party that (a) the receiving Party intends to take actions (satisfactory to both Parties) that will obviate the need for such withholding, in which case the paying Party shall make such payment only after it is instructed to do so by the receiving Party or (b) the paying Party should make such payment and withhold the required amount and pay it to the appropriate Governmental Authority. In such case, the withholding Party shall promptly provide the other Party with copies of receipts or other evidence reasonably required and sufficient to allow the other Party to document such tax withholdings adequately for purposes of claiming foreign tax credits and similar benefits. The Parties will cooperate reasonably in completing and filing documents required under the provisions of any applicable tax laws or under any other applicable Law, in connection with the making of any required tax payment or withholding payment, or in connection with any claim to a refund of or credit for any such payment. The Parties will cooperate to

minimize such taxes in accordance with applicable Laws, including using reasonable efforts to access the benefits of any applicable treaties. Notwithstanding the foregoing, if, as a result of (y) the assignment of this Agreement by Sarepta to an Affiliate or a Third Party outside of the United States or (z) the exercise by Sarepta of its rights under this Agreement through an Affiliate or Third Party outside of the United States (or the direct exercise of such rights by an Affiliate of Sarepta outside of the United States), foreign withholding tax in excess of the foreign withholding tax amount that would have been payable in the absence of such assignment or exercise of rights becomes payable with respect to amounts due to Summit hereunder, then such amount due to Summit will be increased so that the amount actually paid to Summit equals the amount that would have been payable to Summit in the absence of such excess withholding (after withholding of the excess withholding tax and any additional withholding tax on such increased amount). However, if a similar assignment or exercise of rights described in clauses (y) or (z) of the preceding sentence by Summit results in foreign withholding tax in excess of the foreign withholding tax amount that would have been payable in the absence of such assignment or exercise of rights, then any amount due to Summit will not be increased for such excess withholding and, subject to the terms of this Agreement, the required amount will be withheld and submitted to the appropriate Governmental Authority.

9.1.2.

Permitted Disclosures.  Notwithstanding the obligations of confidentiality and non-use set forth above, a receiving Party may provide Confidential Information disclosed to it, and disclose the existence and terms of this Agreement, as may be reasonably required in order to perform its obligations and to exploit its rights under this Agreement, and specifically to (a) Related Parties, and their employees, directors, agents, consultants, advisors or other Third Parties for the performance of its obligations hereunder (or for such entities to determine their interest in performing such activities) in accordance with this Agreement in each case, who are under an obligation of confidentiality with respect to such information that is no less stringent than the terms of this Section 9; (b) governmental or other Regulatory Authorities in order to obtain patents or perform its obligations or exploit its rights under this Agreement; provided that such Confidential Information shall be disclosed only to the extent reasonably necessary to do so, (c) the extent required by Law, including by the rules or regulations of the United States Securities and Exchange Commission or similar regulatory agency in a country other than the United States or of any stock exchange or listing entity, (d) any bona fide actual or prospective acquirers, underwriters, investors, lenders or other financing sources and any bona fide actual or prospective licensee, sublicensees, collaborators or strategic partners and to consultants and advisors of such Party, in each case, who are under an obligation or confidentiality with respect to such information that is no less stringent than the terms of this Section 9 and (e) to Third Parties to the extent a Party is required to do so pursuant to the terms of an Existing Summit In-License. If a Party is required by Law to disclose Confidential Information that is subject to the non-disclosure provisions of this Section 9, then such Party shall promptly inform the other Party of the disclosure that is being sought in order to provide the other Party an opportunity to challenge or limit the disclosure obligations. Confidential Information that is required to be disclosed by Law shall remain otherwise subject to the confidentiality and non-use provisions of this Section 9. If either Party concludes that a copy of this Agreement must be filed with the United States Securities and Exchange Commission or similar regulatory agency in a country other than the United States, then such Party will provide the other Party with a copy of this Agreement showing any provisions hereof as to which the Party proposes to request confidential treatment, will provide the other Party with an opportunity to comment on any such proposed redactions and to suggest additional redactions and will take such Party’s reasonable comments into consideration before filing the Agreement.

Publication and Publicity.

9.2.1.

Publication.  Sarepta and Summit each acknowledge the other Party’s interest in publishing certain key results of the Collaboration. Each Party also recognizes the mutual interest in obtaining valid patent protection and in protecting trade secret information. Consequently, except for disclosures permitted pursuant to Section 9.1 and Section 9.2.3, either Party wishing to make a publication or public presentation that contains the Confidential Information of the other Party shall deliver to the other Party a copy of the proposed written

publication or presentation a reasonable period of time prior to submission for publication or presentation. The reviewing Party shall have the right (a) to propose modifications to the publication or presentation for patent reasons, trade secret reasons or business reasons, and the publishing Party will remove all Confidential Information of the other Party if requested by the reviewing Party and (b) to request a reasonable delay in publication or presentation in order to protect patentable information. If the reviewing Party requests a delay, then the publishing Party shall delay submission or presentation for a period of ninety (90) days (or such shorter period as may be mutually agreed by the Parties) to enable the non-publishing Party to file patent applications protecting such Party’s rights in such information in accordance with Section 12. With respect to any proposed publications or disclosures by investigators or academic or non-profit collaborators, such materials shall be subject to review under this Section 9.2.1 to the extent that Sarepta or Summit, as the case may be, has the right and ability (after using Commercially Reasonable Efforts to obtain such right and ability) to do so.

9.2.2.

Publicity; Use of Names.  Except as set forth in Section 9.1 and Section 9.2.3, no Party shall use the name, trademark, trade name or logo of the other Party or its employees in any publicity, news release or disclosure relating to this Agreement or its subject matter without the prior express written permission of the other Party, except as may be required by Law or expressly permitted by the terms hereof.

13.

TERM AND TERMINATION

13.1.

Term.  This Agreement shall be effective as of the Effective Date and, unless terminated earlier pursuant to Section 13.2, this Agreement shall continue in effect on a Licensed Product-by-Licensed Product and country-by-country basis until expiration of the last Royalty Term to expire under this Agreement (“Term”). Upon expiration of the Term, all licenses granted to Sarepta under Section 7.1 then in effect shall become fully paid-up, perpetual, irrevocable licenses and all licenses granted to Summit under Section 7.2 then in effect shall become fully paid-up, perpetual, irrevocable licenses.

13.2.

Termination Rights.

13.2.1.

Termination for Convenience.  

(a)

By Sarepta. Sarepta shall have the right to terminate this Agreement in its entirety or on a Licensed Product-by-Licensed Product or country-by-country basis at any time after the Effective Date on six (6) months’ prior written notice to Summit.  If Sarepta terminates this Agreement with respect to one or more, but not all, countries in the Sarepta Territory, then those countries will cease being part of the Sarepta Territory commencing on the effective date of such termination.  

(b)

Summit’s Resulting Right. If any termination by Sarepta pursuant to Section 13.2.1(a) prevents Sarepta from satisfying its obligations with respect to the Terminated Licensed Product in the Major European Countries as set forth in Sections 3.3 and 4.1.1, then such termination shall give Summit the right to terminate this Agreement with respect to such Terminated Licensed Product as to the EU by providing written notice to Sarepta within [**] of Summit’s receipt of Sarepta’s notice of termination pursuant to Section 13.2.1(a). If any termination by Sarepta pursuant to Section 13.2.1(a) prevents Sarepta from satisfying its obligations with respect to the Terminated Licensed Product in the Major Option Countries as set forth in Sections 3.3 and 4.1.1, then such termination shall give Summit the right to terminate this Agreement with respect to such Terminated Licensed Product as to the Option Territory by providing written notice to Sarepta within [**] of Summit’s receipt of Sarepta’s notice of termination pursuant to Section 13.2.1(a). The effects of such termination will be as if Summit terminated this Agreement with respect to such Terminated Licensed Product in the EU or the Option Territory, as applicable, pursuant to Section  13.2.2.

13.2.2.

Termination for Cause.  This Agreement may be terminated, in its entirety or on a Licensed Product-by-Licensed Product basis, at any time during the Term upon written notice by either Party if the other Party is in material breach of its obligations hereunder and has not cured such breach within [**] in the case of a payment breach, or within [**] in the case of all other breaches, after notice requesting cure of the breach; provided, however, that if any breach other than a payment breach is not reasonably curable within [**] and if a Party is making a bona fide effort to cure such breach, then such termination shall be delayed for a time period to be agreed by both Parties, not to exceed an additional [**], in order to permit such Party a reasonable period of time to cure such breach.  For the avoidance of doubt, any failure by Sarepta to satisfy its diligence obligations in Sections 2.4, 3.3 or 4.1.1 with respect to a Licensed Product shall be deemed a material breach only with respect to such Licensed Product for purposes of this Section 13.2.2.  If Sarepta fails to satisfy its diligence obligations in Sections 3.3 or 4.1.1 as to a Licensed Product in the Major European Countries or, if applicable, the Major Option Countries, then Summit shall have the right to

terminate this Agreement as to such Licensed Product only in the EU or the Option Territory, as applicable, as a result of such failure.  If Sarepta fails to satisfy its diligence obligations in Sections 3.3 or 4.1.1 as to any country in the Sarepta Territory outside the EU and the Option Territory, then Summit shall have the right to terminate this Agreement as to such Licensed Product only in such country as a result of such failure. If either Party initiates a dispute resolution procedure in accordance with Section 14.3.2 to resolve a dispute, claim or controversy regarding the material breach for which termination is being sought and is diligently pursuing such procedure, then the cure period set forth in this Section 13.2.2 will be tolled during the pendency of such dispute resolution procedure.

13.2.3.

Termination for Safety Reasons.

(a)

Termination by Sarepta.  At any time during the [**] after the Effective Date, Sarepta may terminate this Agreement with respect to the Benzoxazole Licensed Product on not less than [**] prior written notice to Summit if Sarepta reasonably determines based upon its review of the clinical data or upon a determination by an applicable drug safety monitoring board or Governmental Authority that the Benzoxazole Licensed Product caused or is likely to cause a fatal, life-threatening or other Serious Adverse Event that is reasonably expected, based upon then-available data, to preclude continued Development or Commercialization of the Benzoxazole Licensed Product (such termination, a “Safety Termination”).  Upon delivery of any such notice of a Safety Termination, each Party may wind-down its then on-going activities related to the Benzoxazole Licensed Product, including any on-going Clinical Studies, in accordance with Section 13.3.2(c)(ii) (to the extent consistent with applicable Laws).

(b)

Termination by Consensus. The Parties may terminate this Agreement on a Licensed Product-by-Licensed Product basis prior to expiration of the [**] notice period provided in Section 13.3.2(a) upon written agreement if the Parties: (i) reach consensus that the Party proposing the Safety Termination is unable to continue Developing or Commercializing a Licensed Product in the Field in its Territory; and (ii) have completed all applicable wind-down and other transition activities, including those set forth in Section 13.3.2(c)(ii).

13.2.4.

Challenges of Patent Rights.  In the event that Sarepta or any of its Related Parties (a) commences or participates in any action or proceeding (including any patent opposition or re-examination proceeding), or otherwise asserts any claim, challenging or denying the validity or enforceability of any Summit Patent Right or any claim thereof or (b) actively assists any other Person in bringing or prosecuting any action or proceeding (including any patent opposition or re-examination proceeding) challenging or denying the validity or enforceability of any of such Summit Patent Rights or any claim thereof, then (i) Sarepta shall

give notice thereof to Summit within [**] of taking such action (or becoming aware that its Related Party has taken such action) and (ii) Summit will have the right, in its sole discretion to give notice to Sarepta that the licenses granted to Sarepta with respect to all or any portion of the Summit Patent Rights licensed to Sarepta under this Agreement will terminate [**] following such notice (or such longer period as Summit may designate in such notice) unless (x) Sarepta withdraws or causes to be withdrawn all such challenge or (y) in the case of ex-parte proceedings, multi-party proceedings or other patent challenges that Sarepta or Sarepta’s Related Parties do not have the power to unilaterally withdraw or cause to be withdrawn, Sarepta and Sarepta’s Related Parties cease assisting any other party to such patent challenge and, to the extent Sarepta or a Sarepta Related Party is a party to such patent challenge, it withdraws from such patent challenge, in each case, within such [**] period. In the event that Summit is not permitted under Law to terminate the licenses with respect to all Summit Patent Rights under this Agreement, then the Parties agree to construe this provision to permit Summit to terminate only the licenses to that portion of such Summit Patent Rights with respect to which Summit may terminate consistent with applicable Law.  The foregoing shall not apply with respect to (A) any patent challenge described in clause (a) or (b) above that is made in defense of Summit’s assertion of any Summit Patent Right against Sarepta or any of its Related Parties and (B) any patent challenge commenced by a Third Party that after the Effective Date acquires or is acquired by Sarepta or its Related Parties or its or their business or assets, whether by stock purchase, merger, asset purchase or otherwise, provided that such patent challenge commenced prior to the closing of such acquisition.

13.3.

Effect of Termination.

13.3.1.

Termination by Sarepta for Summit Breach.  Without limiting any other legal or equitable remedies that either Party may have, if Sarepta has the right to terminate this Agreement pursuant to Section 13.2.2 in its entirety or with respect to a particular Licensed Product(s) (in the form such Licensed Product exists as of the effective date of termination, a “Terminated Licensed Product”), then Sarepta may elect, upon written notice to Summit, to either:

(a)

Termination. Terminate this Agreement in its entirety, in which case:

(i)
