4.2.

Development Milestone Payments. Subject to the terms and conditions of this Agreement and commencing upon the Effective Date, Sarepta will pay to BioMarin the Milestone Payments set forth in this Section ‎4.2 (Development Milestone Payments) for Royalty Bearing Products, whether the corresponding Milestone Event is achieved by Sarepta or its Affiliates or any of their Sublicensees. Each Milestone Payment set forth in this Section ‎4.2 (Development Milestone Payments) is payable with respect to each Royalty Bearing Product targeting a different Target Exon but only once with respect to all Royalty Bearing Products that target the same Target Exon, and the total payments payable under this Section ‎4.2 (Development Milestone payments) will in no event exceed US $20,000,000 per Target Exon, irrespective of whether the applicable Milestone Event(s) is achieved by Sarepta, its Affiliates or any of their Sublicensees.

Sarepta will notify BioMarin promptly following the achievement of the Milestone Event described in this Section ‎4.3 (Sales Milestone Payment) and will pay the associated Milestone Payment within 30 days following the achievement of the Milestone Event. Notwithstanding the foregoing, on a Royalty Bearing Product-by-Royalty Bearing Product and country-by-country basis, the Net Sales of any Royalty Bearing Product in any country following the expiration of the Royalty Term for such Royalty Bearing Product in such country will be excluded from the calculation of “aggregate Net Sales” for the purpose of determining the Sales Milestone Event under this Section ‎4.3 (Sales Milestone Payment).

(d) Net Sales of a Royalty Bearing Product outside the United States in a Calendar Quarter during and after the BioMarin Option Quarter

If the manufacture, use, performance or sale of any Royalty Bearing Product is Covered by more than one Valid Claim or Patent of the Licensed Patents, multiple royalties will not be due as a result of being so covered. Following the expiration of the applicable Royalty Term in a country in the Territory with respect to a Royalty Bearing Product (but not following an earlier termination of this Agreement), the Sarepta License with respect to such Royalty Bearing Product in such country will be fully-paid, irrevocable, perpetual and royalty-free, on a Royalty Bearing Product-by-Royalty Bearing Product and country-by-country basis.

4.4.2.

Royalty Adjustments for Generic Products. On a Royalty Bearing Product-by-Royalty Bearing Product and country-by-country basis, the royalty payments owed with respect to a Royalty Bearing Product in a country in the Territory pursuant to Section ‎4.4 (Royalties) will be reduced by [**]% of the amounts otherwise payable pursuant to Section ‎4.4.1 (Royalty Rates) commencing in the Calendar Quarter during which one or more Generic Products with respect to such Royalty Bearing Product has captured in aggregate [**]% of the market for such Royalty Bearing Product and continuing for [**].

(b)

BioMarin Cross-License. If BioMarin licenses the Licensed Patents to a Third Party following Sarepta’s request pursuant to Section ‎4.4.3‎(a) (Sarepta Cross-License Request) or Section ‎7.3 (Defense Cost Sharing), then (i) all such Third Party’s products [**] will be subject to [**], respectively, and such Third Party products will be subject to [**] of this Agreement under [**], as applicable

[**], (ii) the terms and conditions of such license agreement will be consistent with the terms and conditions of this Agreement including, without limitation, Section 2 (License Grant), Section 4 (Payment Terms) (other than Section ‎4.4.3 (Third Party License Offset), [**], which sections shall not be included in any such license agreement), Section ‎5 (Records; Audit Rights), Section ‎8 (Confidentiality), Section ‎9 (Representations, Warranties and Covenants), Section ‎10 (Indemnification; Limitation of Liability), Section ‎11 (Term; Termination), Section ‎12.1.1 (Use of Names) and Section ‎13 (General Provisions), and be subject to Sarepta’s prior written approval, which shall not be unreasonably withheld or delayed, (iii) BioMarin will only enter into such license agreement simultaneously with Sarepta’s entry into the Third Party License, (iv) BioMarin will cooperate in good faith to facilitate a comprehensive settlement with such Third Party including providing Sarepta drafts of the proposed license agreement and the opportunity to participate in negotiations with such Third Party, and (v) upon BioMarin’s entry into such license agreement, the royalty rates under this Agreement will be [**].

(c)

4.4.4.

Royalty Holiday for Managed Access Programs.

-17-

4.4.5.

Reports; Payment of Royalty. No sooner than 35 days following the end of each Calendar Quarter until the completion of the final Royalty Term, and within 45 days following the end of each such Calendar Quarter, Sarepta will (a) provide BioMarin with a report (a “Royalty Report”) that includes reasonably detailed information regarding a total monthly sales calculation on a country-by-country basis of gross sales of Royalty Bearing Products, Net Sales of Royalty Bearing Products (detailing all deductions) and all royalties payable for the applicable Calendar Quarter (including any foreign exchange rates used), and (b) pay BioMarin the royalties payable for the applicable Calendar Quarter.

4.4.6.

Late Payments. Any late payments will bear interest, accruing and compounding daily from the date such payment is due, at the lower rate of (a) [**] and (b) the highest rate permitted under Applicable Law.

4.5.

Payment Method.

4.5.1.

Currency. With respect to Net Sales invoiced in U.S. dollars, the Net Sales and the amounts due for royalties under Section ‎4.4.1 (Royalty Rates) will be expressed in U.S. dollars. With respect to Net Sales invoiced in a currency other than U.S. dollars, payments will be calculated based on amounts converted to U.S. dollars using currency exchange rates for the Calendar Quarter for which remittance is made for such royalties. Conversion of Net Sales recorded in local currencies to U.S. dollars will be performed in a manner consistent with Sarepta’s normal practices used to prepare its audited financial statements for external reporting purposes, provided that such practices use a widely accepted source of published exchange rates.

4.5.2.

Method of Payment. All payments due hereunder will be made by wire transfer in U.S. Dollars to the credit of such bank account as may be designated by BioMarin in writing to Sarepta. Any payment which falls due on a date which is not a Business Day may be made on the next succeeding Business Day.

4.6.

Taxes. The Parties shall execute such appropriate documentation as may be necessary to minimize or eliminate any tax withholdings. Notwithstanding such efforts, if Sarepta concludes that tax withholdings under the Applicable Law of any country are required with respect to payments to BioMarin, then Sarepta will first notify BioMarin and provide BioMarin with 20 days to determine whether there are actions BioMarin can undertake to avoid such withholding. During this notice period, Sarepta will refrain from making such payment until BioMarin instructs Sarepta that (a) BioMarin intends to take actions (satisfactory to both Parties) that will obviate the need for such withholding, in which case Sarepta will make such payment only after it is instructed to do so by BioMarin or (b) Sarepta should make such payment and withhold the required amount and pay it to the appropriate

-18-

governmental authority. In such case, Sarepta will promptly provide BioMarin with copies of receipts or other evidence reasonably required and sufficient to allow BioMarin 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 BioMarin hereunder, then such amount due to BioMarin will be increased so that the amount actually paid to BioMarin equals the amount that would have been payable to BioMarin in the absence of such excess withholding (after withholding of the excess withholding tax and any additional withholding tax on such increased amount).

5.	RECORDS; AUDIT RIGHTS

5.1.

Relevant Records.

5.1.1.

Relevant Records. Sarepta will keep, and will cause each of its Affiliates and Sublicensees, as applicable, to keep, accurate books and records of accounting for the purpose of calculating all payments due to BioMarin under Section ‎4 (Payment Terms) (such books and records, collectively the “Relevant Records”). For the three years following the end of the Calendar Year to which each will pertain (“Record Retention Period”), such Relevant Records will be kept by Sarepta or such Affiliate or Sublicensee at each of their principal place of business.

5.1.2.

Audit of Sarepta and its Affiliates. During the Record Retention Period, BioMarin will have the right, at its expense, to cause an independent, certified public accountant chosen by BioMarin and reasonably acceptable to Sarepta to inspect such records of Sarepta and its Affiliates during normal business hours for the purposes of verifying the accuracy of any reports and payments delivered under this Agreement and Sarepta compliance with the terms hereof. Such accountant or other auditor, as applicable, will not

-19-

disclose to BioMarin any information other than information relating to the accuracy of reports and payments delivered under this Agreement. The Parties will reconcile any underpayment or overpayment within 30 days after the accountant delivers the results of the audit. If any audit performed under this Section ‎5.1.2 (Audit of Sarepta and its Affiliates) reveals an underpayment in excess of [**] percent ([**]%) in any Calendar Year, Sarepta will reimburse BioMarin for all amounts incurred in connection with such audit. BioMarin may exercise its rights under this Section ‎5.1.2 (Audit of Sarepta and its Affiliates) only once per Calendar Year per audited entity, only once with respect to any Calendar Year and only with reasonable prior written notice, and in no event with fewer than seven days prior notice, to the audited entity.

5.1.3.

Audit of Sublicensees. During the Record Retention Period, BioMarin will have the right, at its expense, to require Sarepta to make available to an independent, certified public accountant chosen by BioMarin and reasonably acceptable to Sarepta, during normal business hours, such information as Sarepta has in its possession with respect to reports and payments from Sublicensees for the purposes of verifying the accuracy of any reports and payments delivered under this Agreement. If such information as Sarepta has in its possession is not sufficient for such purposes, BioMarin will have the right, at its expense, to cause Sarepta to exercise its right under a Sublicense to cause an independent, certified public accountant (or, in the event of a non-financial audit, other appropriate auditor) chosen by BioMarin and reasonably acceptable to Sarepta to inspect such records of Sublicensee during normal business hours for the purposes of verifying the accuracy of any reports and payments delivered under this Agreement. Such accountant or other auditor, as applicable, will not disclose to BioMarin any information other than information relating to the accuracy of reports and payments delivered under this Agreement and then only to the extent such accountant or other auditor may disclose such information to Sarepta under the terms of the relevant Sublicense. If Sarepta does not have the right to conduct an audit of such Sublicensee for the relevant Calendar Year, Sarepta and BioMarin will meet and use reasonable efforts to agree on an appropriate course of action. The Parties will reconcile any underpayment or overpayment within 30 days after the accountant delivers the results of the audit. If any audit performed under this Section ‎5.1.3 (Audit of Sublicensees) reveals an underpayment to BioMarin in excess of [**] percent ([**]%) in any Calendar Year, Sarepta will reimburse BioMarin for all amounts incurred in connection with such audit. BioMarin may exercise its rights under this Section ‎5.1.3 (Audit of Sublicensees) only once per Calendar Year per Sublicensee, only once with respect to any Calendar Quarter and only with reasonable prior written notice, and in no event with fewer than seven days prior notice, to Sarepta and any audited Sublicensee.

-20-

5.1.4.

Confidential Treatment. All information subject to review under Section ‎5 (Records; Audit Rights) will be deemed Sarepta’s Confidential Information and will be treated in accordance with the confidentiality provisions of Section ‎8 (Confidentiality). BioMarin will cause its applicable auditors and accountants to enter into a reasonably acceptable confidentiality agreement with Sarepta and its Affiliates or Sublicensees, as applicable, prior to any review under Section ‎5 (Records; Audit Rights), which confidentiality agreement will obligate such auditor or accountant to retain all such information in confidence pursuant to terms that are at least as restrictive as the confidentiality and non-use obligations under this Agreement.

6.	INTELLECTUAL PROPERTY ownership and prosecution

6.1.

Patent Prosecution and Maintenance of Licensed Patents.

6.1.1.

Patent Prosecution Committee. The Parties will establish a patent prosecution committee (“PPC”) comprised of at least two representatives from Sarepta and at least two representatives from BioMarin. The PPC will oversee, review and inform decisions relating to the preparation, filing, prosecution and maintenance of the Licensed Patents. Each Party may replace its representatives to the PPC at any time upon written notice to the other Party. Unless otherwise agreed to by the Parties, the PPC will meet each Calendar Quarter during the Term to discuss patent strategy for Licensed Patents, and to review and discuss upcoming substantive communications, responses or proposed filings with patent offices and other government authorities related to the Licensed Patents and the content and positions to be taken in such communications, responses or proposed filings. The PPC will meet in-person or by teleconference. Each Party has the right, but not the obligation, to invite outside patent counsel to attend a PPC meeting upon providing prior written notice to the other Party. Each Party will be responsible for all of its own expenses of participating in PPC meetings, including travel costs. [**]. The Parties will agree on the minutes of each meeting promptly, but in no event later than the next meeting of the PPC. Without limiting BioMarin’s obligations under Section ‎8 (Confidentiality), BioMarin will not, and will ensure that its representatives on the PPC and its outside patent counsel do not, disclose any Sarepta Confidential Information that Sarepta provides to the PPC to any Person other than a Sarepta or BioMarin representative on the PPC, including to any employees, agents, contractors, representatives, directors and advisors of BioMarin and AZL who are not BioMarin representatives on the PPC, without the prior written consent of Sarepta. BioMarin will use all reasonable measures to protect such Sarepta Confidential Information from such unauthorized disclosure, including by securing paper and electronic files that include such Sarepta Confidential Information in a manner that

-21-

makes such Sarepta Confidential Information inaccessible to Persons not authorized to access such information.

6.1.2.

Patent Prosecution. BioMarin will, taking into consideration the recommendations of the PPC and Section ‎6.1.3 (Prosecution Dispute Escalation), prepare, file, prosecute (including in connection with any post-grant proceedings, such as reissues, reexaminations and the like) and maintain (or abandon) the Licensed Patents at BioMarin’s cost, using counsel that is reasonably acceptable to Sarepta. BioMarin will consult and reasonably cooperate with Sarepta or the PPC (as appropriate) with respect to the preparation, filing, prosecution and maintenance of its Licensed Patents, including: (a) allowing Sarepta through its representatives on the PPC a reasonable opportunity and reasonable time to review and comment regarding drafts of substantive communications, responses or proposed filings by BioMarin before any such communications, responses or filings are submitted to any relevant patent office or governmental authority, (b) taking into consideration the comments offered by Sarepta through its representatives on the PPC in any such communications, responses or filings submitted by BioMarin to any relevant patent office or governmental authority, (c) promptly informing Sarepta and the PPC in writing of BioMarin’s disagreement with any such Sarepta comment, if applicable, prior to submitting any such communication, response or filing to any relevant patent office or governmental authority, and (d) resolving any such disagreement in the manner set forth in Section ‎6.1.3 (Prosecution Dispute Escalation) prior to submitting any such communication, response or filing to any relevant patent office or governmental authority. BioMarin shall notify Sarepta in writing at least 10 Business Days prior to the deadline for submitting any filing with respect to any Licensed Patent to the relevant patent office or governmental authority if BioMarin intends to not implement any recommendation of Sarepta or its representatives on the PPC into the relevant filing. If BioMarin informs Sarepta or its representatives on the PPC that it intends not to implement any recommendation of Sarepta or its representatives on the PPC or if BioMarin does not promptly respond to any Sarepta comment on any draft communication, response or filing reasonably in advance of the relevant submission deadline, then, in either case, Sarepta may refer the matter for resolution in accordance with Section ‎6.1.3 (Prosecution Dispute Escalation), in which case the Parties will pursue the dispute resolution process set forth in Section ‎6.1.3 (Prosecution Dispute Escalation) prior to the submission of the applicable communication, response or filing to the relevant patent office or governmental authority.

6.1.3.

Prosecution Dispute Escalation. In the event that the Parties through the PPC disagree with respect to any comment offered in good faith by Sarepta regarding a draft material substantive communication, response or proposed filing by BioMarin under Section ‎6.1.2 (Patent Prosecution) with respect to

-22-

a Licensed Patent, then, before any such communication, response or filing is submitted to any relevant patent office or governmental authority, the Parties will refer the matter to the General Counsels of both Parties for resolution prior to the deadline for the relevant communication, response or proposed filing. If the matter is not resolved by the General Counsels prior to such deadline, then:

(a)

BioMarin will have the right to make the final decision regarding such communication, response or filing after considering Sarepta’s comments in good faith, and

(b)

if such communication, response or filing does not reflect such Sarepta comments then, notwithstanding anything to the contrary in this Agreement or in the Settlement Agreement, if Sarepta brings a Patent Challenge (as defined in the Settlement Agreement) with respect to such Licensed Patent in the country to which such comments pertain, then BioMarin may terminate this Agreement and the Settlement Agreement only with respect to such Licensed Patent in such country (or the entire European Union for a challenge in any country in the European Union) and only with respect to the Follow-On Products (and not any Lead Product).

6.1.4.

Step-in Right. If BioMarin elects to cease prosecution of the Licensed Patents in a country in the Territory in a manner that would prevent the opportunity to obtain an issued Licensed Patent or additional issued Licensed Patents, as the case may be, in such country, then BioMarin will provide Sarepta with written notice as soon as reasonably practicable, but not less than 30 days before any action is required, upon the decision to cease prosecution of such Patent, in which case BioMarin or its Affiliates will permit Sarepta, in Sarepta’s sole discretion, to file or continue prosecution of any such Licensed Patent in such country at Sarepta’s sole expense. If BioMarin elects not to maintain any issued Patent within the Licensed Patents, then BioMarin or its Affiliates will permit Sarepta, in Sarepta’s sole discretion, to maintain any such issued Patent within the Licensed Patents in such country at Sarepta’s sole expense.

6.2.

EU Unitary Patent System. Sarepta and its Affiliates will have the exclusive right to remain in or opt-out of the EU Unitary Patent System for the Licensed Patents, and BioMarin will take no actions inconsistent with such determination and cooperate with Sarepta in support of it exercising its rights hereunder. Without limiting the generality of the foregoing, if Sarepta or its Affiliates opt out of the EU Unitary Patent System with respect to a Licensed Patent prior to the final due date for doing so, then BioMarin will not initiate any action under the EU Unitary Patent System without Sarepta’s prior written approval, in Sarepta’s sole discretion.

-23-

6.3.

Regulatory Filings; Orange Book Listings. Sarepta will have the sole discretion to determine whether to list or de-list a Licensed Patent in the FDA’s Orange Book or its foreign equivalents with respect to a Product, as required or allowed under Applicable Law. To the extent that Sarepta elects to list a Licensed Patent in the Orange Book and foreign equivalents with respect to a Product, it will have the sole right make all filings with Regulatory Authorities in the Territory with respect to the Licensed Patents. At Sarepta’s expense, BioMarin will cooperate with Sarepta’s reasonable requests in connection therewith, to the extent required or permitted under Applicable Law. Upon Sarepta listing a Licensed Patent in the Orange Book or foreign equivalent with respect to a Product pursuant to this Section ‎6.3 (Regulatory Filings; Orange Book Listings), BioMarin agrees to notify AZL of its notification obligations pursuant to Section ‎7.7 (Generic Challenge) and request AZL to cooperate with it in fulfilling its obligations.

6.4.

Patent Coverage Disputes. The Parties will first attempt to resolve any and all disputes between the Parties relating to whether or not a Product of Sarepta (other than a Lead Product in the United States or in the European Union prior to BioMarin’s exercise of the BioMarin Co-Exclusive License Option) is a Royalty Bearing Product (a “Patent Coverage Dispute”) informally through good faith negotiation between the Parties following either Party’s provision of written notice that such Patent Coverage Dispute exists. In the event that Xxxxxxxxxxx Xxxxx, Vice President, Chief Intellectual Property Counsel, on behalf of Sarepta, and Xxxxx Xxxxxxxx, Vice President, Intellectual Property, on behalf of BioMarin, or their respective successors are unable to resolve such Patent Coverage Dispute within 60 days following the provision of such notice, such Patent Coverage Dispute will be resolved through binding arbitration as set forth in this Section ‎6.4 (Patent Coverage Disputes). The arbitration will be initiated and conducted according to the Commercial Arbitration Rules of the American Arbitration Association and the Supplementary Procedures for Large, Complex Disputes (the “Arbitration Rules”). The arbitration will be conducted in Boston, Massachusetts before a panel of three arbiters selected as follows: each Party would appoint one arbiter and the two Party-appointed arbiters would mutually select a third arbiter. All arbiters will be experienced United States patent lawyers practicing in the bio-pharmaceutical industry with significant arbitration experience and experience with patent matters involving RNA-targeted therapeutics. The arbitrators will follow Massachusetts law in adjudicating such dispute. The Parties agree that the arbitrators’ authority will extend solely to resolving such Patent Coverage Dispute, and not to any other matter. The arbitrators will provide a detailed written statement of decision, which may be enforced in any court of competent jurisdiction. The cost of such arbitration will be borne by the unsuccessful Party in such arbitration, including without limitation the costs and expenses of the prevailing Party (including reasonable attorney’s fees). Such arbitration and such results will be the Confidential Information of both Parties. The Parties agree that the Licensed Patents may not be asserted or defended, or their validity challenged in a court of law unless and until the arbitrators provide the written statement of the decision.

-24-

6.5.

Bankruptcy. All rights and licenses granted to Sarepta pursuant to this Agreement are licenses of rights to “intellectual property” (as defined in Section 101(35A) of title 11 of the United States Code (the “Bankruptcy Code”)). Each Party will retain and may fully exercise all of its rights and elections under the Bankruptcy Code. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against BioMarin or any of its Affiliates (collectively, the “Bankrupt Party”) under the Bankruptcy Code or analogous provisions of Applicable Law outside the United States, Sarepta, as a licensee under the Bankrupt Party’s intellectual property, will be entitled to a complete duplicate of (or complete access to, as appropriate) such intellectual property and all embodiments of such intellectual property, which, if not already in Sarepta’s possession, will be promptly delivered to it upon Sarepta’s request therefor.

7.	enforcement AND DEFENSE of the licensed patents

7.1.

Notification. BioMarin will promptly notify Sarepta in writing of its becoming aware of any actual, perceived, or threatened (a) act of direct, contributory or induced infringement or misappropriation of the Licensed Patents and Licensed Know-How, whether or not defendable, or other violation of the Licensed Patents or Licensed Know-How for which a Claim could be brought, a suit could be filed or other legal action could be taken (collectively, “Third Party Infringement Action”); or (b) challenge to the validity, scope, ownership or enforceability of any Licensed Patent or Licensed Know-How, including any declaratory judgment action, revocation action, opposition proceeding, nullity action, interference, derivation action, inter partes review, post-grant review and the like, by a Third Party against or with respect to any Licensed Patents or Licensed Know-How (collectively, “Challenge Action”).

7.2.

Right to Enforce and Defend. Except as otherwise provided in this Section ‎7 (Enforcement and Defense of the Licensed Patents), as between the Parties, Sarepta will have the first right, but not the obligation, to institute a Third Party Infringement Action or Challenge Action, and any such Third Party Infringement Action or Challenge Action initiated by Sarepta will be at Sarepta’s expense, subject to Section ‎7.3 (Defense Cost Sharing). Subject to Section ‎7.7 (Generic Challenge), if Sarepta fails to institute such Third Party Infringement Action or defend a Challenge Action within [**] of its receipt of notice thereof, then BioMarin will have the right, but not the obligation, upon [**] prior notice to Sarepta, to institute any such Third Party Infringement Action or defend any such Challenge Action at its own expense. The Party that undertakes to institute a Third Party Infringement Action or Challenge Action in accordance with this Section ‎7 (Enforcement and Defense of the Licensed Patents) is referred to in this Agreement as the “Enforcing Party.” For clarity, Sarepta is not obligated to lead or continue any Third Party Infringement Action or Challenge Action initiated or defended by BioMarin with respect to the Licensed Patents prior to the Effective Date, including the Actions, except as otherwise expressly provided in the Settlement Agreement.

-25-

7.3.

Defense Cost Sharing. If (a) a Third Party asserts a Third Party Claim and (b) such Third Party (or its Affiliates or licensees) [**], then Sarepta may, in its sole discretion, request BioMarin to license the Licensed Patents to such Third Party under the terms set forth in Section ‎4.4.3(b) (BioMarin Cross-License) as part of a cross-license arrangement. If, within [**] following the applicable Sarepta request under this Section ‎7.3 (Defense Cost Sharing), BioMarin does not offer to license the Licensed Patents to such Third Party under the terms set forth in Section ‎4.4.3(b) (BioMarin Cross-License) and subsequently negotiate in good faith a license agreement with such Third Party in accordance with Section ‎4.4.3(b) (BioMarin Cross-License) for at least [**] following such offer to license or such shorter period as Sarepta may direct, as applicable, then (A) Sarepta may deduct [**]% of the amount of Third Party Royalties actually paid by Sarepta or its Affiliates to such Third Party with respect to any Royalty Bearing Product from amounts payable to BioMarin under Section 4.4 (Royalties) of this Agreement with respect to such Royalty Bearing Product, and (B) Sarepta may deduct [**]% of its reasonable expenses (including attorney’s fees) incurred in defending such Third Party Claim as well as [**]% of the amount of any settlement amounts or damages actually paid by Sarepta or its Affiliates to such Third Party as a result of such Third Party Claim from amounts payable to BioMarin under Section 4.4 (Royalties); provided that, in no event will payments to BioMarin be reduced pursuant to this Section ‎7.3 (Defense Cost Sharing) by more than [**]% of the payments that would otherwise be payable pursuant to Section ‎4.4 (Royalties).

7.4.

Cooperation. The Enforcing Party will have the right to control the Third Party Infringement Action or Challenge Action instituted or defended by it, as applicable, at its own expense. At the Enforcing Party’s request and expense, the other Party will timely commence or join in any such Third Party Infringement Action or the defense of any such Challenge Action whether to establish standing or otherwise, and in any event will cooperate with the Enforcing Party in such Third Party Infringement Action or Challenge Action at the Enforcing Party’s expense. The other Party also will have the right to consult with the Enforcing Party about such Third Party Infringement Action or Challenge Action and to join such Third Party Infringement Action or Challenge Action as a party and to participate in and be represented by independent counsel in such Third Party Infringement Action or Challenge Action at such other Party’s own expense. If BioMarin exercises the BioMarin Co-Exclusive License Option, it will provide Sarepta with reasonable prior written notice of its desire to initiate a Third Party Infringement Action or defend a Challenge Action, such Third Party Infringement Action or such defense of a Challenge Action will be at its sole expense, and BioMarin agrees to cooperate with Sarepta and keep Sarepta reasonably informed of any such Third Party Infringement Action or Challenge Action in the manner provided in this Section ‎7.4 (Cooperation).

-26-

settlement of any such Third Party Infringement Action or Challenge Action that such Enforcing Party controls and will not settle, stipulate to any facts or make any admission with respect to any such Third Party Infringement Action or Challenge Action without the other Party’s prior written consent (not to be unreasonably withheld or delayed) if such settlement, stipulation or admission would: (a) adversely affect the validity, enforceability or scope, or admit non-infringement, of any of the Licensed Patents; (b) give rise to liability of the other Party or its Affiliates; (c) grant to a Third Party a license, sublicense or covenant not to xxx under, or with respect to, any Licensed Patent beyond the scope of the Enforcing Party’s right to do so under this Agreement; or (d) otherwise impair the other Party’s rights in any Licensed Patents or the other Party’s rights under this Agreement.

7.6.

Recoveries. Any and all recoveries resulting from a Third Party Infringement Action or Challenge Action as provided in this Section ‎7 (Enforcement and Defense of the Licensed Patents) will first be applied to reimburse each Party’s costs and expenses in connection with such Third Party Infringement Action or Challenge Action (such recoveries to be applied pro rata in accordance with the costs and expenses incurred by each Party, in the event that the amount of such recoveries is less than the total amount of all such costs and expenses).

-27-

Third Party Infringement Action as a result of such certification will be as set forth in Section ‎7 (Enforcement and Defense of the Licensed Patents); provided that if Sarepta elects not to initiate a Third Party Infringement Action against the Third Party providing notice of such certification within [**] of receipt of such notice, then BioMarin, upon discussing the facts and circumstances with Sarepta, will have the right, but will not be obligated, to initiate the Third Party Infringement Action against such Third Party at its expense and to join Sarepta as a party plaintiff if necessary to bring such a suit, in which event BioMarin will hold Sarepta and its Affiliates harmless from and against any and all costs and expenses of such litigation, including reasonable attorneys’ fees and expenses.

As used herein, the term “Residuals” means any information retained in the unaided memories of a Party’s or its Affiliates’ employees who have had access to the other Party’s Confidential Information pursuant to the terms of this Agreement.

Sarepta Therapeutics and BioMarin Pharmaceutical Inc. Announce Execution of a Global Settlement and a License Agreement Resolving Exon Skipping Patent Litigation

-- Agreement terms resolve global patent proceedings regarding Sarepta’s sale of EXONDYS 51® (eteplirsen) and future Duchenne muscular dystrophy (DMD) exon-skipping products --

CAMBRIDGE, Mass. and SAN RAFAEL, Calif., July 18, 2017 (GLOBE NEWSWIRE) -- Sarepta Therapeutics, Inc. (NASDAQ:SRPT), a U.S. commercial-stage biopharmaceutical company focused on the discovery and development of unique RNA-targeted therapeutics for the treatment of rare neuromuscular diseases, and BioMarin Pharmaceutical Inc. (NASDAQ:BMRN), a leading biotechnology company in therapies for rare genetic diseases, announced today that Sarepta and BioMarin executed a license agreement that provides Sarepta Therapeutics with global exclusive rights to BioMarin’s DMD patent estate for EXONDYS 51 and all future exon-skipping products. BioMarin retains the right to convert the license to a co-exclusive right in the event it decides to proceed with an exon-skipping therapy for DMD. In addition, Sarepta and BioMarin executed a settlement agreement, resolving the ongoing worldwide patent proceedings related to the use of EXONDYS 51 and all future exon-skipping products for the treatment of DMD. The effectiveness of the agreements is subject to closing conditions including execution of necessary approvals by Academisch Ziekenhuis Leiden (AZL) by July 24, 2017.

Under the terms of the license and settlement agreements, Sarepta will make a one-time payment of $35 million to BioMarin and certain additional regulatory and commercial milestone payments for exons 51, 45, 53 and possibly on future exon-skipping products.

In addition, Sarepta will pay royalties to BioMarin as follows:

•

Exon-skipping compounds 51, 45, and 53 and possibly on future exon-skipping products: Sarepta will pay BioMarin 5 percent of net sales through the end of 2023 in the United States; and

•

Exon-skipping compounds 51, 45, and 53 and possibly on future exon-skipping products: Sarepta will pay BioMarin 8 percent of net sales through September 30, 2024 in the European Union and in other countries where certain BioMarin / AZL patents exist.

“Upon their effectiveness, these global license and settlement agreements provide Sarepta worldwide freedom to operate for EXONDYS 51 and our future exon-skipping products,” said Xxxxxxx Xxxxxx, Sarepta’s President and Chief Executive Officer. “The resolution of these legal matters provides us with more certainty to fully focus our resources and energy on our crucial mission of developing innovative medicines to improve the lives of those impacted by DMD around the world."

“We are pleased to reach a global settlement and license agreement with Sarepta that fairly recognizes the important innovation by the Leiden University Medical Center and allows patients certainty that this issue will not create a barrier to access,” said G. Xxxx Xxxxx, BioMarin’s Executive Vice President and General Counsel.

About EXONDYS 51

EXONDYS 51 uses Sarepta’s proprietary phosphorodiamidate morpholino oligomer (PMO) chemistry and exon-skipping technology to skip exon 51 of the dystrophin gene. EXONDYS 51 is designed to bind to exon 51 of dystrophin pre-mRNA, resulting in exclusion of this exon during mRNA processing in patients with genetic mutations that are amenable to exon 51 skipping. Exon skipping is intended to allow for production of an internally truncated dystrophin protein. Data from clinical studies of EXONDYS 51 in a small number of DMD patients have demonstrated a consistent safety and tolerability profile. The pivotal trials were not designed to evaluate long-term safety and a clinical benefit of EXONDYS 51 has not been established.

Important Safety Information

Adverse reactions in DMD patients (N=8) treated with EXONDYS 51 30 or 50 mg/kg/week by intravenous (IV) infusion with an incidence of at least 25% more than placebo (N=4) (Study 1, 24 weeks) were (EXONDYS 51, placebo): balance disorder (38%, 0%), vomiting (38%, 0%) and contact dermatitis (25%, 0%). The most common adverse reactions were balance disorder and vomiting. Because of the small numbers of patients, these represent crude frequencies that may not reflect the frequencies observed in practice. The 50 mg/kg once weekly dosing regimen of EXONDYS 51 is not recommended.

In the 88 patients who received ≥30 mg/kg/week of EXONDYS 51 for up to 208 weeks in clinical studies, the following events were reported in ≥10% of patients and occurred more frequently than on the same dose in Study 1: vomiting, contusion, excoriation, arthralgia, rash, catheter site pain, and upper respiratory tract infection.

There have been reports of transient erythema, facial flushing, and elevated temperature occurring on the day of EXONDYS 51 infusion.

This press release contains statements that are forward-looking. Any statements contained in this press release that are not statements of historical fact may be deemed to be forward-looking statements. Words such as "believes," "anticipates," "plans," "expects," "will," "intends," "potential," "possible" and similar expressions are intended to identify forward-looking statements. These forward-looking statements include statements about the license agreement providing Sarepta with global exclusive rights to BioMarin’s DMD patent estate for EXONDYS 51 and all future exon-skipping products; the settlement agreement resolving the ongoing worldwide patent proceedings related to the use of EXONDYS 51 and all future exon-skipping products for the treatment of DMD; the payments and royalties

that Sarepta will be making as part of the settlement and license agreements; the settlement and license agreements providing for Sarepta's worldwide freedom to operate for EXONDYS 51 and Sarepta’s future exon-skipping products; the settlement providing Sarepta with the certainty to fully focus its resources and energy on its crucial mission of developing innovative medicines to improve the lives of those impacted by DMD around the world; and the statement that the patent proceedings between the parties will not create for patients a barrier to access to the innovation by the Leiden University Medical Center.

These forward-looking statements involve risks and uncertainties, many of which are beyond Sarepta's control. Known risk factors include, among others: the settlement and license agreements may not become effective if their conditions to effectiveness are not met within the required deadline; the parties may not be able to fulfill their commitments and obligations under the settlement and license agreements; any future claims of infringement by other third parties; the expected benefits and opportunities related to the settlement and license agreements between the parties may not be realized or may take longer to realize than expected due to challenges and uncertainties regarding the sales of EXONDYS 51 and the research and development of future exon-skipping products; Sarepta may experience significant fluctuations in sales of EXONDYS 51 from period to period and, ultimately, Sarepta may never generate sufficient revenues from EXONDYS 51 to reach or maintain profitability or sustain its anticipated levels of operations; Sarepta may never receive regulatory approval to its future exon-skipping products due to a variety of reasons including that the results of additional research may not be consistent with past results or may not be positive or may otherwise fail to meet regulatory approval requirements for the safety and efficacy of product candidates; and even if Sarepta obtains regulatory approvals, it may not achieve any significant revenues from the sale of such products; Sarepta may not have worldwide freedom to operate for EXONDYS 51 and Sarepta’s future exon-skipping products due to future proceedings brought by other parties.
