2.CONDUCT OF THE RESEARCH.

2.1Objective. Subject to the terms and conditions of this Agreement, the parties agree that, during the Research Term, Company shall perform the Research in accordance with the Research Plan, and each party shall contribute the materials and services specified therein, with the goal of identifying and developing small molecule therapeutics for use in the Field.

2.2Research Plan; Contributions. The Research Plan sets forth the activities proposed to be conducted by Company, together with an anticipated schedule for completion of such activities. Company agrees to use commercially reasonable efforts to achieve the research milestones (the “Research Milestones”) and research goal(s) described in Exhibit B (attached hereto) on the schedule set forth therein and to incorporate feedback from the Foundation’s scientific advisors. The parties will jointly review the research goals, activities and schedule set forth in the Research Plan and may, by mutual written agreement, amend the Research Plan from time to time during the course of the Research Term and, in connection therewith, may (i) modify the funding amounts and schedule set forth in Section 4.1, (ii) add additional Research Milestones or goals to Exhibit B, or (iii) provide for Additional Payments, as appropriate. Each party shall contribute to the Research the materials and services specified in the Research Plan, and the Foundation shall use commercially reasonable efforts to assist Company in obtaining favorable licensing terms to SMA Research Tools necessary or useful for the Research.

2.3Principal Scientist. The Principal Scientist is considered essential to the Research being performed, and no substitution may be made without the prior written agreement of the Foundation. If for any reason the Principal Scientist ceases to be employed by Company or otherwise becomes unavailable, or cannot continue to oversee the conduct or completion of the Research, Company will propose a successor whose appointment as Principal Scientist shall be subject to the approval of the Foundation, such approval not to be unreasonably withheld. If the parties are unable to agree upon a successor within 90 days after the Principal Scientist ceases his involvement in the Research, this Agreement may be terminated by the Foundation pursuant to Section 7.3.

2.4The Research.

(a)During the Research Term, Company shall conduct each of the Research Projects in accordance with this Agreement and the Research Plan. Company shall disclose the results of all Research activities to the Foundation in accordance with Section 2.7. Company may select, after disclosing the applicable criteria to the Foundation, one or more compounds that have been validated in secondary assay(s) and have suitable in vitro potency, or otherwise meet the criteria set forth in the Research Plan (or otherwise mutually agreed upon by the parties) for further evaluation (each such compound being hereinafter referred to as a “Hit”), following which, as more fully described in the Research Plan, Company shall: (i) assess each Hit (and, as the parties deem appropriate consistent with the Research Plan, any analog, derivative or formulation thereof) with the goal of identifying one or more compounds that have suitable properties for administration to humans (each such compound being hereinafter referred to as a “Lead Candidate”); and (ii) evaluate and, if appropriate based on such evaluation, optimize each Lead Candidate for therapeutic administration to humans.

(b)The parties shall mutually agree upon a strategy for medicinal chemistry follow-up on Lead Candidates and further pharmacology studies, formulation development, safety and toxicity studies, dosing studies or other preclinical work at Company, or at Company’s option, through external collaboration or licensing with a Third Party. As promptly as practicable after identification of one or more Lead Candidates, Company shall provide the Foundation with total cost estimates for continued Lead Optimization and development of such Lead Candidates, and the Foundation may elect to fund, in the form of cash payments to Company, some, all or none of this work upon reasonable advance notice to Company. In addition, the Foundation may act to secure funding from Third Parties, and/or assist Company to obtain alternative sources of external funding, and in each case such funding would be administered through and governed by this Agreement as specified in a written agreement with any such Third Party, such Agreement to specify the impact of such alternative sources of funding on the payment obligations of the Company under Section 4.3.

(c)Company shall disclose the results of all Research activities regarding Hits and Lead Candidates to the Foundation in accordance with Section 2.7, and the parties shall consult with each other with the objective of identifying at least one Drug Candidate suitable for progression to the preparation and filing of an IND in the Field and, contingent on the effectiveness of such IND, progressing such Drug Candidate into human clinical trials in the most expeditious manner.

2.5Performance Standards. Company shall conduct the Research in good scientific manner, and in compliance in all material respects with the requirements of applicable laws and regulations and with applicable good laboratory practices, to attempt to achieve its objectives efficiently and expeditiously. Company shall maintain (either as its own internal resources, or via subcontract) laboratories, offices and all other facilities reasonably necessary to carry out the activities to be performed by it pursuant to the Research Plan. In conformity with standard pharmaceutical and biotechnology industry practices and the terms and conditions of this Agreement, Company shall prepare and maintain, or shall cause to be prepared and maintained, complete and accurate written records, accounts, notes, reports and data with respect to activities conducted pursuant to the Research Plan. Upon reasonable advance notice, Company agrees to make its employees and non-employee consultants reasonably available at their respective places of employment to consult with the Foundation on issues or questions arising during the Research Term.

2.6Research Term. The initial phase of the Research is expected to require one year to reach the primary overall objective of Lead Candidate identification. The parties may, from time to time, on a Research Project-by-Research Project basis, extend or modify the Research Term by mutual written agreement (the initial one-year period and any extensions or modifications together shall hereinafter referred to as the “Research Term”).

2.7Communication; Research Reports. On a regular basis during the Research Term (but no less frequently than [**]), the parties shall conduct meetings, either in person or by telephone or video conference, to discuss the progress of the Research and strategies for achieving the objectives of the Research in an expeditious manner. Company shall keep the Foundation fully informed as to all results and discoveries (including, without limitation, assay development and all Hits and potential Lead Candidates and Drug Candidates) made in the

course of performing activities under the Research Program at these meetings. In furtherance of the foregoing, on a [**] basis, Company shall prepare, and deliver to the Foundation no later than [**] days after the conclusion of [**] during the Research Term, a reasonably detailed written summary report of the results and progress of the Research during [**] (each, a “Research Report”). In addition, the Foundation may, at its option, during the Research Term, schedule up to [**] formal program review meetings with Company personnel and those of Foundation’s Third Party advisors who (i) have agreed to confidentiality restrictions substantially similar to those contained in this Agreement, and (ii) are reasonably acceptable to Company. Such meetings will be held at the times and locations mutually agreed upon by the parties. The purpose of such meetings will be to review the progress of the Research relative to the Research Plan.

2.8Subcontracts. Company may perform some of its obligations under the Research Plan through one or more subcontractors, provided that (a) none of the rights of either party hereunder are diminished or otherwise adversely affected as a result of such subcontracting, and (b) Company will at all times be responsible for the performance and, except as otherwise agreed by the parties in writing, payment of such subcontractor; provided, however, that the Company may use payments received by it pursuant to Section 4.1 to pay for such subcontractor(s). In determining whether any Company obligations under the Research Plan will be performed in-house or by a Third Party subcontractor, Company shall take into consideration Company’s then-current capabilities and the relative efficiency of utilizing such internal capabilities versus Third Party services.

2.9Additional Screening. The Foundation may request that Company test up to [**] compounds identified by other Foundation partners (“Third Party Compounds”) on a blinded basis. Company agrees to test such Third Party Compounds on behalf of the Foundation and to disclose the results of such screening to the Foundation, provided that the relevant assay is already being run by the Company on its own Compounds. Such testing shall be performed pursuant to a separate materials transfer agreement to be negotiated in good faith by the parties prior to provision of any compounds or related information, which agreement shall contain reasonable and customary terms to protect the parties’ respective intellectual property rights. Without limiting the generality of the foregoing, each such materials transfer agreement shall provide that in no event shall any Third Party Compound become the property of the Company, nor shall any Third Party Compound become subject to royalty or other reach-through payment obligations to Company or its affiliates as a result of such screening by Company.

3.	DEVELOPMENT OF PRODUCTS.

3.1Clinical Development Strategy. As soon as Company reasonably believes that it has identified a Drug Candidate for which it proposes to file an IND in the Field, Company will notify the Foundation in writing, and the parties will promptly discuss in good faith how to proceed with the clinical development of such Drug Candidate, taking into consideration the interests of SMA patients, the intellectual property and regulatory landscape and the commercial potential of the Drug Candidate. The parties agree to consider in good faith collaborating with the NIH in preclinical or clinical development activities regarding such Drug Candidate. Should Company elect to proceed with clinical development of the Drug Candidate, it may do so directly. In the alternative, at its discretion, the Company may decide to enter into a

collaboration with one or more Third Parties for clinical development and/or commercialization of the Drug Candidate through licensing or other arrangement; provided, however, that if the Foundation has funded (or caused to be funded) [**], then until [**], any such collaborations shall be subject to the Foundation’s approval (which shall not be unreasonably withheld). If Company wishes to pursue clinical development of a Drug Candidate, the Company will consult with the SMA Foundation on the clinical trial network that will be used. Although the parties currently expect to use the clinical trial network established by the Foundation, the clinical trial network to be used shall be determined in good faith by Company in its reasonable judgment. For any Drug Candidate for which it files an IND, Company agrees to consider in good faith whether to obtain, (a) “Orphan Product” designation from the FDA, and (b) research funding from the FDA’s Office of Rare Diseases to support human clinical trials conducted for such Drug Candidate. The parties acknowledge that if the Drug Candidate is [**], or [**] due to [**] and [**], investment by Company in further development of such Drug Candidate may not be in the best interests of Company’s stockholders, and therefore shall not be required under this Agreement, and the failure to engage in such further development shall not be the basis of a Reversionary License under Section 6.1(c). In such case, the parties may elect to enter into an additional sponsored research agreement under which the Foundation would provide funding for further development efforts by Company, but neither party shall have any obligation to enter into such additional agreement.

3.2Conduct of Clinical Development. Except as set forth in Section 3.1 above or as otherwise agreed by the parties in writing, Company shall be responsible for clinical development of any Drug Candidate for which Company files an IND. Company shall use commercially reasonable efforts to develop and commercialize (whether directly, through an Affiliate, or in collaboration with one or more Third Parties, through licensing or some combination of the foregoing) at least one Product. The parties anticipate that an IND will be submitted within [**] years of commencement of IND-enabling toxicology studies for a Lead Candidate, but the parties acknowledge that [**], and therefore [**], to be a [**]. Notwithstanding the preceding provisions of this Section 3.2, in no event shall Company have any obligation (i) to pursue clinical development or commercialization of any Drug Candidate which is [**], or which [**] the [**] due to its [**] and [**], or (ii) in the absence of complete funding by (or arranged by) the Foundation, to pursue clinical development or commercialization of any Drug Candidate which is not, [**]. In addition, Company shall not be obligated to pursue clinical development or commercialization of a Drug Candidate if the pharmaceutical preparation, composition of matter, method of manufacture and/or method of use of such Drug Candidate is covered by Patents of a Third Party, unless a license under such Third Party Patents is available to Company (or its Affiliate or Licensee, as applicable) on commercially reasonable terms (a “Third Party Patent License”).

3.3Disclosure Regarding Company Efforts. Company will keep the Foundation appropriately informed about clinical trial progress and commercialization efforts with respect to Products, and in any event, Company shall provide the Foundation with [**] written reports summarizing any significant development or commercialization events that have occurred during the applicable [**]-month period, provided that such reports may be incorporated into any Research Reports then being prepared and delivered under Section 2.7.

4.	PAYMENTS.

4.1Research Funding by the Foundation. For the conduct of the Research, and subject to the completion of the applicable Research Milestones described in Exhibit B (attached hereto), the Foundation shall pay a total of US$[**] to Company on the schedule specified below:

(a)within 10 days after the Effective Date, the Foundation will pay to Company US$400,000;

(b)within 30 days after the Foundation’s receipt of notice from Company of the achievement of Milestone 1 in Exhibit B attached hereto, the Foundation will pay Company US$400,000;

(c)within 30 days after the Foundation’s receipt of notice from Company of the achievement of Milestone 2 in Exhibit B attached hereto, the Foundation will pay Company US$400,000; and

(d)within 30 days after the Foundation’s receipt of notice from Company of the achievement of Milestone 3 in Exhibit B attached hereto, the Foundation will pay Company US$400,000.

The Foundation may delay any payment until such time as the milestones in the Research Plan are met (or as may otherwise be mutually agreed in writing). For purposes of clarification, the foregoing payments shall be non-refundable, and each of the foregoing payments shall be payable only once. The Foundation acknowledges that the foregoing payments represent only a portion of the total cost of performing the Research. Notwithstanding the foregoing,, except as agreed pursuant to Section 4.2, the Foundation will not be obligated to pay any additional amounts in connection with the Research.

4.2Additional Payments. In addition to the amounts specified in Section 4.1, upon mutual written agreement of the parties, the Foundation may make, or cause to be made, additional research funding payments to Company in connection with any modification of the Research Plan.

4.3Milestone Donation by Company. Within [**] days after the end of the first fiscal quarter in which Company has received an aggregate of US$[**] in Product Revenues, Company shall make a payment to the Foundation (or, at the Foundation’s option, one or more other non-profit organizations or academic or research institutions designated by the Foundation in writing) in the applicable amount set forth below pursuant to clause (a), (b) or (c), whichever one (and only one) of the following applies:

(a)

[**];

(b)

[**]; or

(c)

[**].

In addition to the foregoing milestone payments, and provided that the Foundation provided funding for Lead Optimization of Products hereunder at the level set forth in the first paragraph of 4.3(c), within [**] days after the end of the first calendar year during which Company has received an annual aggregate in that year of US$[**] in Product Revenues, Company shall make a payment to the Foundation equal to 100% of the sum of the Research Funds and the Additional Payments. For the avoidance of doubt, such additional payment shall be a one-time payment only, regardless of any additional Product Revenues.

If [**] in good faith believes that making the applicable payment(s) specified in this Section 4.3 on the schedule set forth above will prevent Company from achieving a reasonable profit margin on commercial sales of Products, [**] may reduce any such payments due in the applicable calendar or fiscal quarter by [**]%, or such other reduction as the parties shall in good faith agree, with any reduction carried forward on a quarter-by-quarter basis (subject to the same reductions in each subsequent quarter) until paid in full.

4.4Reporting of Product Revenues. From and after such time as Company first receives any Product Revenues and until such time as Company has paid in full the amount due under Section 4.3 (if any), Company shall deliver to the Foundation (or a Third Party designated in writing by the Foundation) quarterly written reports of Product Revenues received by Company and its Affiliates, which reports shall indicate the total Product Revenues received. Company shall keep, and shall cause its Affiliates to keep, complete and accurate records pertaining to the receipt of Product Revenues in sufficient detail to permit the Foundation to confirm the accuracy of such reports.

4.5Exchange Rate; Xxxxxx and Place of Payment. All payments hereunder shall be payable in U.S. dollars. When conversion of payments from any foreign currency is required for purposes of calculating Product Revenues, such conversion shall be at the exchange rate used by Company (or, where applicable, a Licensee) throughout its accounting system (which shall, in any event, be commercially reasonable) during the quarter for which such report is due. All payments owed under this Agreement shall be made by check, or by wire transfer in immediately available funds to a bank and account designated in writing by the party entitled to receive payment, unless otherwise specified in writing by such party.

4.6Taxes. Each party will pay any and all taxes levied on account of any payments made to it under this Agreement out of the amounts it is to receive hereunder. If any taxes are required to be withheld by the party making payment, such party will (a) deduct such taxes from the payment made by it, (b) timely pay the taxes to the proper taxing authority, (c) send proof of payment to the other party and certify its receipt by the taxing authority within [**] days following such payment, and (d) be deemed to have paid such amount to the other party hereunder.

4.7Audits. The Foundation shall have the right to cause an independent, certified public accountant reasonably acceptable to Company to audit the records of Company and its Affiliates to confirm the accuracy of Company’s reports of Product Revenues for a period covering not more than the preceding [**] years. Such audits may be exercised during normal business hours upon reasonable prior written notice to Company and no more than [**] per year. Prompt adjustments shall be made by the parties to reflect the results of such audit. The

Foundation shall bear the full cost of such audit unless such audit discloses an underreporting of Product Revenues by Company of more than [**]% during any calendar year, in which case, Company shall bear the full cost of such audit.

5.	CONFIDENTIALITY.

5.1Confidentiality. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the parties, the parties agree that, during the Research Term and for a period of [**] years thereafter, each party (the “Receiving Party”) will maintain in confidence all Confidential Information disclosed to it by the other party (the “Disclosing Party”), provided that, with regard to Confidential Information which is trade secret information, such obligation shall extend thereafter until such information is no longer a trade secret of the Disclosing Party. The Receiving Party may use the Confidential Information of the Disclosing Party only to the extent required to accomplish the purposes of this Agreement. The Receiving Party shall use at least the same standard of care as it uses to protect proprietary or confidential information of its own to ensure that its employees, agents, consultants and other representatives do not disclose or make any unauthorized use of the Disclosing Party’s Confidential Information. Each party will promptly notify the other upon discovery of any unauthorized use or disclosure of the other party’s Confidential Information.

5.2Exceptions. The obligations of confidentiality contained in Section 5.1 will not apply to the extent that it can be established by the Receiving Party by competent proof that such Confidential Information: (a) was already known to the Receiving Party, other than under an obligation of confidentiality, at the time of disclosure by the Disclosing Party; (b) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the Receiving Party; (c) became generally available to the public or otherwise part of the public domain after its disclosure and other than through any act or omission of the Receiving Party in breach of this Agreement; (d) is independently discovered or developed by the Receiving Party without the use of Confidential Information of the Disclosing Party; or (e) was disclosed to the Receiving Party, other than under an obligation of confidentiality, by a Third Party who had no obligation to the Disclosing Party not to disclose such information to others.

5.3Authorized Disclosure. Notwithstanding any other provision of this Agreement, disclosure of Confidential Information shall not be precluded if such disclosure is in response to a valid order of a court or other governmental body of competent jurisdiction of the United States or any political subdivision thereof or is otherwise required by law or regulation; provided, however, that the Receiving Party shall, to the extent practicable, first have given notice to the Disclosing Party and shall have made a reasonable effort to obtain a protective order requiring that the Confidential Information so disclosed be used only for the purposes for which the order was issued or the law or regulation required or to seek other confidential treatment of such information.

5.4Publication. The parties acknowledge and agree that the SMA research community and medical professionals treating SMA patients will benefit from disclosure of the Data as soon as practicable. Accordingly, should the Foundation wish to publish any Confidential Information contained in a Research Report, it shall provide Company with [**] days’ advance notice of such publication (the “IP Filing Period”) to allow Company to file

patent applications covering the Company Technology disclosed in such Research Report; provided, however, that at Company’s reasonable request, the IP Filing Period shall be extended for an additional [**] days if necessary for the filing of appropriate patent applications covering Company Technology disclosed in or apparent from such Research Report. During the IP Filing Period, the Foundation shall maintain as confidential the Data and the Research Report provided to Foundation by Company. Notwithstanding the foregoing, in no event shall Foundation disclose the structures of any chemical compound being researched or developed by Company in any publication or other public forum without the prior written consent of Company. Except as expressly set forth in this Agreement, the Foundation shall not have the right to use the Data to develop, commercialize, market or sublicense any commercial offering of any product or service based on the Data. The Company shall provide in each [**] Research Report a summary section which is suitable for immediate public disclosure and the Foundation may release copies of such portions of each Research Report and supporting Data to any Third Party investigator who requests such material from the Foundation in writing; provided, however, that said Third Party investigator first executes Company’s non-disclosure agreement (it being understood that such non-disclosure agreement will not prohibit said Third Party investigator from applying his or her knowledge of the Data to further SMA research and/or to treatment of SMA patients, but will prohibit him or her from transferring such Data except as incidental and necessary to treating SMA patients). The Foundation will treat all other Data in each Research Report as Company Confidential information. To the extent that any journal or other forum in which the Foundation proposes to publish or disseminate the Data requires the authorship or participation of one or more Company employees or contractors who participated in the Research or in the development of a Drug Candidate or Product, Company shall use commercially reasonable efforts to cause such individuals to cooperate with the Foundation in making such publication and, as necessary or appropriate, to be named as authors (or co-authors) of such publication.

2.	Continuing Research.

(a)The parties agree to the modification of the Research Plan and related budget attached as Exhibit SA-1 to allow for Company to perform continued research activities (the “DC Research”) with respect to [**] Research Projects previously funded under the Agreement and the First Amendment. The goal of such research will be the presentation by Company of one (1) Development Candidate from one (1) Research Project for further discussion with Foundation with respect to potential funding of development of such Development Candidate by Foundation, and continuation of one (1) backup program with respect to the other Research Project (the “Secondary Research Project”). The expected duration of the DC Research is [**] months from the Second Amendment Effective Date (the “DC Timeline Goal”).

(b)Company shall conduct such DC Research (i) in accordance with Exhibit SA-1, subject to amendment by the JSC as provided in this Second Amendment, and (ii) in accordance with the terms of the Agreement as amended herein, including but not limited to Company’s obligations under Section 2.5 of the Agreement (captioned “Performance Standards”).

(c)In connection with such DC Research, the Research Term shall be extended, without interruption, until the earliest of (i) the date upon which the JSC first designates a Development Candidate, (ii) the date which is [**] years following the Second Amendment Effective Date or (iii) the effective date of any termination of the Research Term pursuant to Second Amendment Section 3.

(d)The parties will fund the overall total cost of the DC Research based on the Research Plan and related budget attached as Exhibit SA-1, with Foundation contributing approximately [**]% and Company contributing approximately [**]% of such overall total cost of the DC Research as more explicitly specified in such budget, such overall total cost not to exceed $[**] (the “Research Cap”) and the Foundation’s share of such total cost not to exceed $[**].

When invoicing Foundation or developing or presenting any budget related to the Research Plan, Company will in all cases apply the FTE rates specified in Exhibit SA-1 to the applicable category of FTE, and no additions or changes to the FTE categories or rates specified in Exhibit SA-1 shall be made by Company absent prior written consent of Foundation. Company will promptly respond to all requests by Foundation for additional information regarding such out-of-pocket costs. Company’s commitment, between [**] and [**], of [**] dollars ($[**]) in funding towards the DC Research shall be available to Company in the form of an invoice credit against Company’s share of the cost of the DC Research until expended and shall count towards the Research Cap.

vii

Promptly after the Second Amendment Effective Date, Company will provide Foundation with an invoice for [**] percent ([**]%) of the amount that Company spent between [**] and the Second Amendment Effective Date to perform the DC Research. Such invoice shall include the information specified in (A), (B) and (C) within this Second Amendment Section 2(d) and shall be payable within [**] days of receipt by Foundation. The entire amount paid by Foundation pursuant to such invoice shall count towards the Research Cap and towards Foundation’s share of the Research Cap.

(i) Subject to Second Amendment Section 2(d)(ii), Foundation shall not be responsible for its share of any DC Research costs that exceed the budget for any calendar quarter unless:

(1) such costs exceed the budget for such calendar quarter by less than [**] dollars ($[**]) or [**] percent ([**]%) (whichever is less);

(2) such costs exceed the budget for such calendar quarter by more than [**] dollars ($[**]) or [**] percent ([**]%) (whichever is less) but less than [**] percent ([**]%) and Company provided written notice to Foundation prior to incurring such budget overrun; or

(3) such costs exceed the budget for such calendar quarter by more than [**] percent ([**]%) and Foundation approved such budget overrun in writing before it was incurred.

(ii) If at any time during the Second Amendment Term, the total cost incurred in the performance of the DC Research during the period from the Second Amendment Effective Date until the end of the most recent calendar quarter exceeds the cumulative budget for such period by [**] dollars ($[**]) or more, then Second Amendment Section 2(d)(i) shall not apply to any subsequent cost overruns and Foundation shall not be responsible for its share of any additional costs that exceed the applicable budget for any subsequent quarter unless Foundation approved such budget overrun in writing before it was incurred.

(e)Foundation may provide its share of the budget under the Research Plan via other sources of funding, subject to prior agreement of the parties and the existing terms of the Agreement. One hundred percent (100%) of all funds, if any, received by Company during the Second Amendment Term from the Department of Defense directed to the DC Research or the Development of a Development Candidate as a result of the advocacy of the Foundation will count toward the Foundation’s share of the costs incurred in connection with the Research Plan; provided, however, that [**] in the [**] pursuant to [**] of the Agreement. At Foundation’s request, Company shall promptly complete all paperwork required or reasonably useful to secure receipt by Company of such funds from the Department of Defense.

(f)Company may provide its share of the budget via government grants or grants from nonprofit organizations; provided however, that, except for mandatory licenses and similar or related rights granted to government entities, Company’s acceptance of such grants shall not have any effect on Foundation’s rights pursuant to this Agreement; further provided, however, that with respect to any nonprofit organizations that have as a specific aspect of their general

viii

mission the funding of research on SMA, Company shall first seek Foundation’s written consent and the parties shall negotiate in good faith any required amendments to this Agreement or separate agreements to accommodate grants from such organizations, with the guiding principle that this Agreement remain the primary document governing the conduct of the DC Research by the parties. Company shall use Commercially Reasonable Efforts to obtain additional funding for the Secondary Research Project from government grants or grants from nonprofit organizations (subject to the provisions set forth in the preceding sentence with respect to funding from any nonprofit organizations that have as a specific aspect of their general mission the funding of research on SMA); provided however, that, except for mandatory licenses and similar or related rights granted to government entities, Company’s acceptance of such grants shall not have any effect on Foundation’s rights pursuant to this Agreement. If Company obtains such funding in an amount that exceeds Company’s share of the budget for the Secondary Research Project, Company shall notify Foundation in writing and the JSC shall revise the Research Plan and related budget to reflect the additional work to be performed on the Secondary Research Project with such funds, (i) which additional work shall be under the purview of the JSC and the compounds resulting from such work shall remain Drug Candidates, Reversion Candidates, or Development Candidates, as the case may be, and (ii) which revised budget shall not require the Foundation to contribute any money to pay for or reimburse Company for research performed with respect to any aspect of the revised Research Plan for which Company has received such grant funds.

(g)If (i) it becomes evident to either party at any time, based on budget forecasts or progress in the Research Plan, that a [**] may [**] for [**], or that the [**], or (ii) the [**] is [**] (each of the foregoing, a “Cost/Timeline Issue”), then either party may, on written notice to the other, call a special meeting of the JSC to address such Cost/Timeline Issue. At such meeting, representatives of each party shall present information in their control with respect to the reasons for such Cost/Timeline Issue, and (if applicable) each party’s plan or recommendation for addressing such Cost/Timeline Issue. The JSC shall review and address such Cost/Timeline Issue, and shall determine which of the following actions the parties shall pursue:

(1)develop, approve, and follow an amendment to the Research Plan (such amendment, the “Corrective Plan”) to address the Cost/Timeline Issue, which may (subject to the written consent of the affected party in such party’s sole discretion) require either party to [**] the DC Research, or provide that the [**] in which case (x) the [**] shall be [**] and/or, if the [**] is more than [**] years after the Second Amendment Effective Date, then the Research Term shall be deemed amended to extend until the earliest of (i) the date upon which the JSC first designates a Development Candidate, (ii) the [**], or (iii) the effective date of any termination of the Research Term pursuant to Second Amendment Section 3, and (y) in addition to their other obligations under the Agreement, the parties shall duly perform their respective obligations pursuant to such Corrective Plan; provided, however, that after the adoption of a Corrective Plan, failure to achieve the [**] or [**] shall not be deemed, by itself, to be a breach of this Agreement, but shall entitle either party to terminate the Research Term pursuant to Second Amendment Section 3;

(2)restructure the Research Plan and related budget in a manner that resolves the Cost/Timeline Issue; provided, however, that such restructuring shall not obligate either party to [**] of the [**] or be deemed to [**]; or

(3)determine that continuation of the DC Research would be futile, in which case the JSC shall recommend to the parties that they terminate the DC Research; provided further, that following such recommendation either party shall have the right to terminate the Research Term pursuant to Second Amendment Section 3.

(h)If the members of the JSC fail to unanimously agree upon one of the three actions described in Second Amendment Section 2(g) (1), (2) and (3), then the matter shall be referred to the parties’ Chief Executive Officers, and if the parties’ Chief Executive Officers do not agree upon one of such three actions within [**] days after matter referral, then either party shall have the right to terminate the Research Term pursuant to Second Amendment Section 3. If the affected party does not approve the Corrective Plan within [**] days after it is first formally proposed, then either party shall have the right to terminate the Research Term pursuant to Second Amendment Section 3.

3.Special Termination. In addition to the rights to terminate this Agreement as provided in Article 7 of the Agreement, either party shall have the rights to terminate the Research Term as provided in Second Amendment Section 2(g)(1), 2(g)(3) or 2(h) (any such termination of the Research Term, a “Special Termination”).

6.Information Concerning other SMA Efforts. The parties acknowledge that a goal of Foundation in funding the DC Research is to identify and advance the compound most likely to advance rapidly to human clinical trials directed towards the treatment, mitigation or prevention of SMA, and that therefore the parties may have an interest in negotiating funding of other research and development efforts conducted by Company instead of, or in addition to, the Research Projects. In furtherance of this objective, Company will make available to Foundation on a confidential basis regular reports with respect to progress and summary data with respect to Company’s other internal efforts directed towards the approval of a compound for the treatment, mitigation or prevention of SMA. In addition, Company will make available to Foundation general product profiles showing, on a comparative basis, the status of potential Development Candidates from the DC Research against other potential therapeutic agents being pursued by Company in the treatment, mitigation or prevention of SMA (whether internal or in collaboration with Third Parties) in the format provided in Exhibit SA-3 to this Second Amendment; provided, however, that such obligation shall not require Company to breach any condition of any agreement in effect as of the Second Amendment Effective Date. Company will use Commercially Reasonable Efforts to ensure that it is able to share the information specified in this Second Amendment Section 6 with respect to any Third Party agreements entered in to following the Second Amendment Effective Date, and may only enter into such Third Party Agreements if it notifies Foundation reasonably in advance of entering in to such agreements to allow further discussions and potential negotiations with such Third Party with respect to such sharing of information. If, based on information made available pursuant to this Second Amendment Section 6, either party is of the opinion that a change in funding or approach may be advisable, then such party may propose to the JSC, and the JSC shall conduct, an evaluation of the merits of such proposed change that includes a report and recommendation thereon to the parties.

0.Xxxxxxxxxx Access to Company Meetings Following Declaration of a Development Candidate. Following the JSC’s determination that a particular compound is a Development Candidate and through the earlier of Regulatory Approval, abandonment of Development of such Development Candidate, or the granting of a Reversionary License to Foundation, Company shall invite a representative of Foundation (to be designated by Foundation) to observe regularly scheduled monthly meetings of the Company team charged with Development of such Development Candidate, subject to the terms of Second Amendment Section 18(f); provided, however, that failure of Foundation to designate such representative or failure of such representative to attend such meetings shall not constitute a breach of this Agreement. Company may request that Foundation representative recuse themselves from such meetings (or portions of such meetings) (a) that do not relate specifically to a Development Candidate, (b) to prevent the breach of an applicable legal or regulatory obligation of confidentiality or privacy or avoid a conflict of interest, (c) to protect the attorney-client privilege, and/or (d) to preserve intellectual property rights.

8.	Development of Products.

(a)

Article 3 of the Agreement (captioned “Development of Products”) shall, as of the Second Amendment Effective Date, be amended and restated as follows:

“3.DEVELOPMENT OF PRODUCTS.

“3.1Development Plan and Development Deadline Document. Upon selection of a Development Candidate, the JSC will meet to prepare a plan for the Development of such Development Candidate (such plan, the “Development Plan” for such Development Candidate”) and to conduct a formal review of and prepare a comprehensive update to Exhibit SA-4A to the Second Amendment (the “Development Deadline Document”) that reflects anticipated activities directed towards Development and commercialization of such Development Candidate through Regulatory Approval in the United States, in each case taking into consideration available information concerning such Development Candidate, the interests of SMA patients, the intellectual property and regulatory landscape and the commercial potential of the Development Candidate. The parties acknowledge and agree that Exhibit SA-4A takes into account many delays in Development and receipt of Regulatory Approval that, while possible, are not anticipated as of the Second Amendment Effective Date to be likely; Company’s expectations, as of the Second Amendment Effective Date, of the activities required to obtain Regulatory Approval and its goal timelines for completing such activities are set forth in Exhibit SA-4B. When preparing the Development Plan and updating the Development Deadline Document for each Development Candidate, the JSC shall consider whether to obtain, (a) “Orphan Product” designation from the FDA, and (b) research funding from the FDA’s Office of Rare Diseases or other government agencies to support human clinical trials conducted for such Development Candidate, in each case taking into consideration the protection of intellectual property rights and confidential information. The Development Plan shall set forth, in at least the level of detail included in the Company’s or its Licensee’s plans for developing other preclinical or clinical (whichever reflects the status of the Development Candidate at such time) pharmaceutical products, both major and minor Development activities planned to be conducted with respect to such Development Candidate by or on behalf of Company or its Affiliates or Licensees, the anticipated timeline for performing such activities, the goals of such activities and the anticipated timeline for achieving such goals. The Development Deadlines Document shall set forth the deadline by which each major Development activity must be performed by on behalf of Company or its Affiliates or Licensees if the Company wishes to avoid granting the Foundation the right to obtain a Reversionary License pursuant to Section 3.3 of the Agreement. No change can be made to any Development Plan or Development Deadline Document without the approval of the JSC unless such change is approved by the parties’ respective Chief Executive Officers pursuant to Second Amendment Section 5(d) or 5(e), is implemented by Baseball Arbitration

in accordance with Second Amendment Sections 5(d) and 17, or is approved by the Foundation in accordance with Second Amendment Section 9(b)(1).

“3.2Diligence. Prior to selection of a Development Candidate, Company shall (i) perform the activities set forth in the Research Plan in a timely and complete manner, (ii) use Commercially Reasonable Efforts to achieve the goals of the DC Research within the time and budget allotted therefor in the Research Plan, and (iii) also have the research and Development obligations set forth in Section 2.5 of the Agreement. Following selection of a Development Candidate, Company shall use Commercially Reasonable Efforts to Develop and commercialize (whether directly, through an Affiliate, or in collaboration with one or more Third Parties, through licensing or some combination of the foregoing, all in compliance with the other applicable terms of this Agreement), for the treatment, mitigation or prevention of SMA or any other disease, indication or medical condition approved in writing by Foundation, at least one Product from such Development Candidate. In the event that the Development of a Development Candidate [**] toxicology studies governed by good laboratory practices (“GLP Toxicology Studies”) that causes Company to [**] that [**] is [**], then Company shall promptly notify Foundation in writing and Company shall spend up to [**] dollars ($[**]) Developing a Reversion Candidate through the start of GLP Toxicology Studies, provided that such Development does not [**] to [**] that such [**]. Upon the initiation of GLP Toxicology Studies for such Reversion Candidate, it shall be deemed a Development Candidate and Company shall have the diligence obligations set forth in the second sentence of this Section 3.2 of the Agreement. In the event that the Development of a Development Candidate [**] of [**] that [**] to [**] that such [**], then Company shall promptly notify Foundation in writing and Company shall, within [**] days of such notice, notify Foundation that Company has decided to do one of the following: (a) Develop one or more potential or actual Reversion Candidates or Lead Candidates at its own expense and in accordance with the terms and conditions of this Agreement, (b) Develop one or more potential or actual Reversion Candidates or Lead Candidates if Foundation is willing to pay for [**] percent ([**]%) of the costs of such Development for a [**] month period while the parties negotiate in good faith a separate agreement governing the further Development of such potential or actual Reversion Candidates or Lead Candidate(s); provided, that in the event the parties are unable to reach such separate agreement following good faith negotiations, then Company shall have [**] days following the end of such [**] month period to notify the Foundation of its decision to elect either option (a) or (c), or (c) stop all Development work on potential and actual Reversion Candidates or Lead Candidates and Development Candidates. If Company chooses option (a), then Company shall use Commercially Reasonable Efforts to Develop such Reversion Candidates and/or Lead Candidates through the start of GLP Toxicology Studies; upon the initiation of GLP Toxicology Studies for any such Reversion Candidate or Lead Candidate, it shall be deemed a Development Candidate and Company shall have the diligence obligations set forth in the second sentence of this Section 3.2 of the

xxi

Agreement. If Company chooses option (c), then upon written notice (a “Reversion Notice”) to Company, Foundation shall have the Reversionary License and other rights set forth in Section 6.1(c)(2) of the Agreement.

“3.3Development Benchmarks. Following designation of a Development Candidate, and in addition to Company’s general diligence obligation set forth in Section 3.2 of the Agreement, Company shall use Commercially Reasonable Efforts to perform the activities set forth in the Development Plan in accordance with the timeline specified therein and to complete each activity set forth in the Development Deadline Document prior to the applicable deadline specified therein, as such Development Plan or Development Deadline Document may be amended consistent with the terms of this Agreement, with respect to Development of a Product based on such Development Candidate; provided, however, that:

“(a)the JSC shall conduct a formal review of and comprehensive update to such Development Plan and Development Deadline Document on an annual basis to reflect, on a good faith basis, information from the DC Research, ongoing clinical or supportive non-clinical trials, or other factors that may impact the activities, timelines, milestones and goals set forth such Development Plan or the deadlines set forth in such Development Deadline Document;

“(b)a failure of Company, despite Commercially Reasonable Efforts, to meet any deadline set forth in a particular Development Deadline Document (as amended by the JSC) with respect to the relevant Development Candidate (each, a “Benchmark Trigger”) shall not create a breach of the Agreement, but shall instead trigger the availability of a right on the part of Foundation to obtain a Reversionary License in accordance with the following terms:

“(i)if Foundation believes a Benchmark Trigger has occurred, it shall provide written notice to Company setting forth in reasonable detail those aspects of the Development Deadline Document that have created such Benchmark Trigger.

“(ii)Company shall have [**] days to respond to a notice of Benchmark Trigger, which response shall either be (1) to cure the Benchmark Trigger (if it is capable of being cured), or (2) to propose a corrective plan to address the Benchmark Trigger, which shall take the form of a proposed amendment to the Development Deadline Document.

“(iii)if Company proposes a corrective plan to address the Benchmark Trigger, Foundation shall have [**] days to accept or reject such corrective plan. The parties may extend such [**] day period by mutual consent to engage in good faith negotiations

xxii

directed towards arriving at a mutually-agreeable form of such corrective plan with respect to such Benchmark Trigger.

“(iv)if Company fails to respond to a Benchmark Trigger notice or cure the applicable Benchmark Trigger within [**] days of such Benchmark Trigger Notice, or, following the acceptance of a corrective plan for a Benchmark Trigger by Foundation fails to use Commercially Reasonable Efforts to execute such corrective plan, or following a PTC Corporate Change the entity primarily responsible for Company’s obligations under this Agreement fails to provide an M&A Certification as more fully set forth in Second Amendment Section 9(b)(4), then immediately as of such occurrence Foundation shall have the right to obtain the Reversionary License and other rights set forth in Section 6.1(c)(2) of the Agreement (a “Buy-Out Right”).

“(v)Foundation may exercise its Buy-Out Right by providing written notice (a “Buy-Out Notice”) to Company and the first installment payment described in Section 6.1(c)(3)(iii)(A) of the Agreement, such Buy-Out Notice to be effective upon the occurrence of both (A) receipt by Company and (B) availability of funds with respect to such first installment payment (provided that such funds shall be deemed to be available on the [**] business day after the Company’s receipt of such initial payment if the Company does not deposit such payment within [**] after such receipt). Upon the effectiveness of such Buy-Out Notice, the terms of Section 6.1(c)(2) of the Agreement shall apply.

“(vi)notwithstanding the foregoing, if Foundation fails to exercise a Buy-Out Right within [**] years of the date of the accrual of such Buy-Out Right, and other than with respect to the circumstances giving rise to such Buy-Out Right Company is in compliance with the terms of this Agreement, then such Buy-Out Right shall lapse and no longer be exercisable by Foundation. For clarity, the foregoing operates on a Buy-Out Right by Buy-Out Right basis, with Foundation having a full [**] year period to exercise each Buy-Out Right.

“3.4Decisions to Discontinue Development or Commercialization.

(a)At the request of Company, the JSC shall determine, based on a comparison of test data for a particular Development Candidate (both alone and in combination with another treatment) and for the applicable Available Product and through the application of objective criteria previously established by the JSC (or by a mutually agreed independent technical expert if the JSC is not able to agree upon such objective criteria within [**] days after either party provides written notice to the other that

xxiii

it intends to arrange for a technical expert to decide such criteria), which criteria shall include without limitation [**] and [**], whether such Development Candidate (both alone and in combination with another treatment) appears to be less desirable as a therapeutic option in the Field than such Available Product. If, following such a determination, Company informs Foundation in writing that it intends to cease further Development and commercialization of the applicable Development Candidate, then Foundation shall have: (i) upon Foundation’s written notice to Company (such notice, a “Reversion Notice”), a Reversionary License and all other rights set forth in Section 6.1(c)(2) of the Agreement if such Available Product [**] (a “[**]”), or (ii) a Buy-Out Right if such Available Product is a [**], such right to be exercisable by Foundation on the terms provided in Sections 3.3(b)(v) and (vi) of the Agreement.

(b)Company shall notify Foundation in writing if Company has, in its good faith judgment, decided that a particular Development Candidate is not commercially viable, which decision shall not be based, in whole or in part, upon the size of the addressable patient population for such Development Candidate. Such notice shall include a written explanation of the basis for Company’s decision. Unless the parties enter into a separate agreement pursuant to which [**] the Development or commercialization of such Development Candidate, Foundation shall, upon written notice to Company (such notice, a “Reversion Notice”), have a Reversionary License and all other rights set forth in Section 6.1(c)(2) of the Agreement.

(c)Company shall notify Foundation in writing if Company has, in its good faith judgment, determined that (i) based on advice of outside patent counsel, the pharmaceutical preparation, composition of matter, method of manufacture or method of use of a particular Development Candidate is covered by at least one issued and apparently valid and enforceable United States Patent of a Third Party and (ii) it is not possible for Company (or its Affiliate or Licensee, as applicable) to obtain a license under such Third Party Patents on commercially reasonable terms (a “Third Party Patent License”). Upon receipt of such notice from Company and provision by Foundation of a written notice to Company (such notice, a “Reversion Notice”), Foundation shall have a Reversionary License and all other rights set forth in Section 6.1(c)(2) of the Agreement.

(d)Company shall notify Foundation in writing if Company has, in its good faith judgment, decided to cease all Development and commercialization of a particular Development Candidate and it believes that such cessation is not a breach of the obligations set forth in Section 3.2 of the Agreement. Such notice shall include a written explanation of the basis for Company’s belief. Unless the Foundation notifies Company in writing that it does not agree with such belief and that Company is

xxiv

obligated to continue Development and commercialization of such Development Candidate in accordance with Sections 3.2 and 3.3 of the Agreement, then upon Foundation’s written notice to Company (such notice, a “Reversion Notice”), Foundation shall have a Reversionary License and all other rights set forth in Section 6.1(c)(2) of the Agreement.”

(b)The parties acknowledge their continued interest in Research Project B in the area of [**] which is [**], and their good faith intention to continue negotiations (including negotiations with any Third Parties) with respect to finding a way to fund and advance research directed towards Research Project B. Therefore, notwithstanding anything to the contrary in this Second Amendment, the amendments effectuated by this Second Amendment shall not apply to such Research Project B or any Lead Candidates identified during the course of such Research Project B. Instead, the terms of the Agreement (including those amendments implemented pursuant to the First Amendment) as they existed prior to amendment by this Second Amendment shall continue to apply, after the Second Amendment Effective Date, exclusively to such Research Project B and any Lead Candidates identified during the course of such Research Project B.

9.PTC Corporate Change:

(a)M&A Approval Request. Company shall have the option to notify a designated representative of Foundation in writing (an “M&A Approval Request”) no later than [**] days prior to the entry into a definitive written agreement involving a PTC Corporate Change. Such M&A Approval Request shall include the identity of the proposed acquiring or merging entity or entities, the expected relationship (if any) between Company and its Affiliates, Company’s shareholders, and Company’s management following such PTC Corporate Change, and the expected impact of such PTC Corporate Change on Company’s obligations under the Agreement. In addition, subject to appropriate confidentiality protections and the consent of the potential acquiring or merging entity or entities (to the extent such information is information of the potential acquiring or merging entity or entities or relates to the economics or financial terms of the potential PTC Corporate Change), Company shall promptly provide to Foundation’s designated representative any supplemental information concerning such potential PTC Corporate Change as Foundation shall reasonably request. If Foundation responds to such M&A Approval Request by consenting to such proposed PTC Corporate Change prior to Company’s entry into a definitive written agreement involving a PTC Corporate Change, then the terms and conditions of this Agreement shall remain in full force and effect without alteration, and Foundation shall sign such documents and provide such consents as may be reasonably required to effectuate the proposed PTC Corporate Change as described in such M&A Approval Request. If Foundation does not respond prior to Company’s entry into a definitive written agreement involving a PTC Corporate Change, or responds by denying consent prior to Company’s entry into a definitive written agreement for such PTC Corporate Change, then the consequences in Second Amendment Section 9(b) shall apply. Having given an M&A Approval Request to Foundation, Company shall not enter into a definitive written agreement involving a PTC Corporate Change contemplated in such M&A Approval Request prior to the earlier of (i) receipt

xxv

of a response from Foundation as specified in this Second Amendment Section 9(a), or (ii) [**] days following the provision of such M&A Approval Request to Foundation.

(b)Parallel Notification Option. If with respect to a particular definitive written agreement that would result in the a PTC Corporate Change, Company has not given the M&A Approval Request provided for in Second Amendment Section 9(a), or if Company has given such M&A Approval Request and Foundation has either failed to respond within [**] days or responded by denying consent, then within [**] of entering into such definitive written agreement, Company shall provide written notice thereof to a designated representative of Foundation (the “M&A Notice”).

10.Partnering.

(a)Company shall have the primary responsibility to evaluate the need for and timing of Collaboration Activities.

(b)During any period in which Company is not actively pursuing Collaboration Activities, Company shall report to the JSC on [**] basis Company’s views of the partnering/collaboration marketplace for drug discovery and lead optimization efforts at a similar stage to efforts under the DC Research or, if a Development Candidate has been declared, the partnering/collaboration marketplace for development candidates at a similar stage of development to such Development Candidate.

(c)If Company determines to actively pursue Collaboration Activities, whether at its own initiative or in response to inquiries from Third Parties, Company will first seek input from the JSC on the nature, scope, and potential terms of a transaction arising in connection with such Collaboration Activities, as well as a rank-ordered summary list of preferred potential counterparties to such transaction. To the extent prepared by Company rather than received by Company from a potential counterparty, Company shall also provide the JSC with an opportunity to review a draft term sheet and related materials in support of its proposed Collaboration Activities. The JSC shall promptly provide input on Company’s overall approach to Collaboration Activities, as well as specific input on any term sheet or related materials provided to the JSC.

(d)Prior to Company commencing formal term sheet negotiations or contractual negotiations with any Third Party in connection with Collaboration Activities, Company shall first notify Foundation in writing concerning such negotiations (a “Partnering Notice”). Such Partnering Notice shall be accompanied by any available drafts of term sheets or contracts, or if not available, a summary of the proposed transaction to the extent available, in either case subject to redactions of financial terms to the extent required to comply with any confidentiality agreements with the potential counterparty. Following receipt of a Partnering Notice, Foundation and Company shall have the following rights and obligations in connection with the proposed transaction described in the Partnering Notice (regardless of whether, in the course of negotiations, the terms change from those described the original Partnering Notice):

(i)Foundation shall designate a representative to serve in an advisory capacity with respect such transaction and, if requested by Company, to participate in negotiations subject to appropriate confidentiality protections; provided, however, that such representative shall not have the power to commit Foundation to enter into any

amendments to the Agreement absent formal written approval by an appropriately authorized officer of Foundation.

(ii)Foundation may designate legal counsel and [**] of Foundation, each subject to appropriate confidentiality protections, to review and provide comments upon proposed term sheets and contracts for such transaction subject to reasonable time frames consistent with overall progress and status of negotiations and not less than [**]percent ([**]%) of the timeframe specified by Company for the receipt of comments from its senior management. For clarity, such reasonable time frames may be as short as [**] if, in Company’s reasonable judgment, such time frames are required to support a successful negotiation process and such time frames are not less than [**] percent ([**]%) of the timeframe specified by Company for the receipt of comments from its senior management. If requested by the potential counterparty, Company shall have the right to redact financial terms from such term sheets and contracts. In reviewing and commenting on such proposed term sheet and contracts, Foundation counsel and designated representative shall indicate the relative importance of their comments, and if practicable a range of potential responses for negotiation purposes. Company shall use Commercially Reasonable Efforts to implement comments and negotiating positions suggested by Foundation’s counsel and/or representative, with due consideration given to the relative importance assigned to the comments and reflecting the outcome of any discussions between Company and Foundation’s counsel and/or representative with respect to modification of such comments. In addition, Company shall, as non-negotiable contractual terms, require (1) that the counterparty commit, in response to the JSC’s invitation, to sending a representative of such counterparty to such JSC meetings or portions of meetings as the JSC shall request for the purposes of informing, discussing and serving in an advisory role with respect to decisions regarding the progress of and all future plans for the DC Research and the Development and commercialization of the Reversion Candidates, Development Candidate(s) and Product(s) that are the subject of the agreement between Company and such counterparty, (2) an acknowledgement that the JSC shall remain the sole governance body for all research, Development and commercialization decisions regarding the DC Research and the Development and commercialization of Reversion Candidates, Development Candidates and Products that are the subject of the agreement between Company and such counterparty (which acknowledgement may include a clarification that the JSC’s role as such sole governance body shall not prevent the Company or its Licensee from making decisions necessary or useful to implement decisions made by the JSC regarding research, Development, commercialization, and Collaboration Activities with respect to Drug Candidates, Reversion Candidates, Development Candidate(s) and Product(s), so long as such implementation decisions are consistent with and faithful to the intent of the JSC’s decision), (3) that to the extent the counterparty will assume responsibility for Development of a Development Candidate or Product in any country, that such counterparty assume the obligations and rights of Company pursuant to Second Amendment Section 13 in that country, (4) an acknowledgement that the counterparty’s rights and licenses from Company with respect to Reversion Candidates, Development Candidates and Products will terminate upon a Special Termination or Company’s receipt of a Reversion Notice or Buy-Out Notice and an obligation in such circumstance for the

xxix

counterparty to grant the licenses and rights specified in Section 3 of this Second Amendment and Section 6.1(c)(2) of this Agreement (including licenses and rights to (A) all intellectual property that, if developed, acquired or otherwise Controlled by Company, rather than such counterparty, would be Company Technology or Data (“Licensee Technology” and “Licensee Data”, respectively) and (B) all INDs, NDAs or similar regulatory filings made or obtained by such counterparty with respect to the relevant Reversion Candidates, Development Candidates and Products) and perform the activities specified therein in each case as if such counterparty were Company, and (5) third party beneficiary rights for Foundation in the event that such counterparty fails to fulfill any of the foregoing obligations.

(iii)Prior to the conclusion of contractual negotiations pursuant to such Partnering Notice, Company shall schedule at least [**] with representatives of the negotiating team of potential counterparties to the transaction and the representatives designated by Foundation pursuant to the foregoing subsections (i) and (ii) to discuss Foundation’s goals and interests with respect to such proposed transaction. Unless otherwise agreed by Foundation, Company shall use Commercially Reasonable Efforts to cause [**] to take place in person at a location convenient to the New York metropolitan area.

If required by the Company’s confidentiality agreement with the potential counterparty, Company shall have the right to redact financial terms from such proposed final draft of the definitive written agreement. As promptly as reasonably possible, but in no event later then [**] business days following receipt by the JSC members of such proposed final draft of the definitive written agreement and summary, the JSC shall convene a meeting to either approve or deny for such proposed transaction; provided, however, that if Company has otherwise complied with requirements of this Second Amendment Section 10, Foundation shall only be entitled to cast its JSC vote against such proposed transaction if it agrees either (i) to fund [**] percent ([**]%) of ongoing Development and commercialization costs for the applicable Development Candidate(s) or Product(s), or (ii) [**] and any related rights pursuant to Section [**]; and provided further, that failure of either party to make itself available within the time frames specified in this Second Amendment Section 10(e) shall entitle the other party to either approve or deny the proposed transaction in the name of the JSC without the requirement of holding an actual JSC meeting. If the JSC denies approval in accordance with this Second Amendment Section 10(e), Company shall not enter into such proposed definitive written agreement, but shall have the right to continue the applicable negotiations consistent with this Second Amendment Section 10 for the purposes of achieving a form of such definitive written agreement acceptable to the JSC.

(f)Following the entry into a transaction pursuant to this Second Amendment Section 10, the following additional terms and conditions will apply:

“(5)If Foundation makes a final decision, with respect to each and every Reversion Candidate, that it has no interest in performing or having performed (including through a sublicensee), at such time or at any point in the future, any further research, Development, or commercialization upon such Reversion Candidate pursuant to the Reversionary License, then it shall provide written notice thereof to Company, and Company shall be entitled to [**] and this Agreement on written notice to Foundation.”

13.Clinical Trials and Access to Materials. The terms and conditions of this Second Amendment Section 13 shall apply equally to each Licensee as if such Licensee were Company, shall be included in the agreement pursuant to which Company grants rights to such Licensee with respect to any Drug Candidate or Product, and Foundation shall be a third party beneficiary with respect to such terms and conditions and shall have the right to take action directly against such Licensee if such Licensee fails to comply with such terms and conditions.

(a)SMAF Clinical Trials Advisory Committee. Foundation shall have the right, but not the obligation, to create a committee of experts to advise Foundation and Company on clinical trials and expanded access with respect to Development Candidates and Products (the “SMAF Clinical Trials Advisory Committee”). Such SMAF Clinical Trials Advisory Committee shall consist of such individuals as Foundation may designate, but shall include at least one clinical investigator with experience in the Field, [**]. The SMAF Clinical Trials Advisory Committee shall have, as one of its principal mandates, the responsibility of balancing (i) the rapid and efficient Development and commercialization of Development Candidates and Products for the benefit of all potential patients in the Field and (ii) the appropriateness, based on available safety and efficacy information with respect to such Development Candidates and Products, of providing access to such Development Candidates or Products to individual patients via the extension protocols to Company Clinical Trials or expanded access programs further

xxxix

described in Second Amendment Sections 13(b) and 13(c). Such SMAF Clinical Trials Advisory Committee may establish its own procedures for meetings and decision-making.

(b)

Company Clinical Trials.

(1)Foundation shall have the right, but not the obligation, to assist with patient recruitment for any Company Clinical Trial involving SMA patients by (i) referring to Company (or, at Company’s request, referring directly to any clinical investigator at a clinical trial site for the applicable Company Clinical Trial) up to [**] SMA patients meeting the enrollment criteria for the applicable Company Clinical Trial and identified by Foundation or its designee, and/or (ii) proposing up to [**] clinical trial sites with access to appropriate patient populations for such Company Clinical Trial. Company shall use Commercially Reasonable Efforts to enable such patients to be enrolled in such Company Clinical Trial consistent with the applicable enrollment criteria, protocol, and target patient number for such Company Clinical Trial (it being understood that such patients should be given priority over other patients who are equally qualified to participate in such Company Clinical Trial, provided that the final decision regarding such enrollment is made by the clinical investigator and/or clinical trial site personnel of the investigating institution), and to contract with such clinical trial sites for such Company Clinical Trial. If Foundation, in its sole discretion, determines not to assist in patient recruitment for any Company Clinical Trial, then it shall so inform Company and Company shall assume all responsibility for patient recruitment and selection of clinical trial sites.

(2)Each time that Company commences the drafting of a clinical trial protocol for a Development Candidate or Product and at reasonable times thereafter, Company will discuss with Foundation Company’s plans for making such Development Candidate or Product available to participants in such clinical trial after the completion of such trial. If mutually agreed by the parties based on such discussions, or if recommended by the SMAF Clinical Trials Advisory Committee in its sole discretion, Company will submit to the appropriate Regulatory Agency a suitable extension protocol and corresponding informed consent form providing for administration of such Drug Candidate or Product for at least [**] beyond the term provided for in a particular Company Clinical Trial. Company shall use Commercially Reasonable Efforts to obtain the applicable Regulatory Agency’s approval of such extension protocol and informed consent and subsequent approval from the Institutional Review Boards at the locations where such Company Clinical Trial is being conducted; provided, however, that the proposed [**] period for such extension protocol may be shortened based on the request or advice of the applicable Regulatory Agency. Upon receipt of such approvals, Company shall provide, in accordance with the approved extension protocol, such Development Candidate or Product to those SMA patients who enrolled in such Company Clinical Trial pursuant to this Second Amendment Section 13(b) and wish to continue to receive such Development Candidate or Product after the completion of such Company Clinical Trial (such patients, the “Enrollees”). For so long as Company is continuing to develop or seek approval from a Regulatory Agency for such Development Candidate or Product, and subject either to mutual agreement of Company and Foundation or to the recommendation of the SMAF Clinical Trials Advisory Committee in its sole discretion, Company shall use commercially reasonably efforts to obtain approval for an amended or new extension protocol providing for continued administration of such Development Candidate or Product to the Enrollees, and Company shall

provide such Development Candidate or Product to the Enrollees in accordance with any such approved protocol. In any case in which Company, [**], does not concur in the decision to commence or continue any extension protocols pursuant to this Second Amendment Section 13(b)(2), then Company’s obligations to assist with such extension protocols and continue to supply such Development Candidate or Product to Enrollees shall [**], directly or indirectly, [**], and [**] of Development Candidate or Product to Enrollees.

(3)If Company stops Developing or seeking approval from a Regulatory Agency of a Development Candidate or Product for which it filed an extension protocol pursuant to Second Amendment Section 13(b)(2), and either the parties mutually agree or the SMAF Clinical Trials Advisory Committee in its sole discretion (but having considered any safety issues) recommends that the Enrollees continue to have access to such Development Candidate or Product for a longer period than provided for in any existing extension protocol submitted by Company with respect to such Development Candidate or Product, then upon Foundation’s request, Company shall facilitate Foundation’s efforts to arrange for prolonged continued access to such Development Candidate or Product for some or all of the Enrollees by taking all reasonable actions requested by Foundation (consistent with the SMAF Clinical Trials Advisory Committee’s recommendations, if applicable), including without limitation: (i) either (1) transferring Company’s IND for such Development Candidate or Product to Foundation or its designee or (2) providing Foundation or its designee with a right of reference to the manufacturing-related information and safety and efficacy data in Company’s IND or Drug Master File or equivalent regulatory filing (as applicable) so that Foundation or its designee can submit its own IND with respect to such continued access; (ii) providing (for the shorter of [**] months or the amount of time necessary for Foundation or its designee to establish an alternative supply of equivalent clinical grade product) such Development Candidate or Product to Foundation or its designee for administration to such Enrollees in accordance with any extension protocol for which Foundation or its designee has obtained approval from the FDA or the applicable Agency; (iii) assisting Foundation or its designee with obtaining an alternative, equivalent clinical grade supply of such Development Candidate or Product by (1) facilitating Foundation’s or its designee’s negotiation of a supply agreement with Company’s manufacturer of such Development Candidate or Product or (2) providing technology transfer and other technical assistance reasonably requested by Foundation to enable Foundation or its designee to manufacture such Development Candidate or Product; and (iv) providing Foundation with a non-exclusive, fully paid, sublicensable license under Company Technology and Data, and solely to the extent reasonably necessary for Foundation to exercise its rights under the foregoing license, to Company Base IP (provided, that the license granted hereunder to Foundation [**] or [**] or [**] to perform or have performed on its behalf any and all activities necessary or reasonably useful to provide continued access to such Development Candidate or Product in accordance with this Second Amendment Section 13(b)(3). In any case in which Company, [**], does not concur in the decision to commence or continue any extension protocols pursuant to this Second Amendment Section 13(b)(3), then Company’s obligations to assist with such extension protocols and continue to supply such Development Candidate or Product to Enrollees shall [**], directly or indirectly, [**], and [**] of Development Candidate or Product to Enrollees. In connection with the foregoing, Foundation, [**], shall maintain clinical trial and/or product liability insurance, as applicable, in an amount consistent with industry standards and only if available on commercially reasonable terms, and shall [**] with respect to such insurance, with

xli

respect to losses arising out of or related to the activities contemplated under this Second Amendment Section 13(b)(3). Foundation shall provide a certificate of insurance evidencing such coverage to Company upon request.

(c)

Expanded Access Program.

(1)At such a time as the parties mutually agree, or the SMAF Clinical Trials Advisory Committee in its sole discretion determines, that results from Company Clinical Trials and other Development activities with respect to the applicable Development Candidate or Product support expanded access to such Development Candidate or Product for patients with SMA, then Company and Foundation shall cooperate to establish such an expanded access program in which at least [**] SMA patients identified by Foundation who do not meet the enrollment criteria for a particular Company Clinical Trial (whether or not such Company Clinical Trial is directed to SMA patients) for such Development Candidate or Product (such patients, the “Patients”) may gain access to such Development Candidate or Product. Company agrees that at its earliest reasonable opportunity following the commencement of such cooperation (e.g., at a meeting with FDA), Company will inquire about the feasibility of an expanded access protocol for such Drug Candidate or Product for SMA purposes and will invite a designee of Foundation with appropriate medical or regulatory experience to participate in discussions with the FDA regarding the establishment and maintenance of such expanded access program. In connection with such expanded access program, at Foundation’s request and consistent with any recommendation made by the SMAF Clinical Trials Advisory Committee, Company will either (i) submit to the FDA a protocol that is reasonably acceptable to Foundation and calls for administering such Development Candidate or Product to the Patients or (ii) notify Foundation that it will not be making such a submission and facilitate the submission and approval of such a protocol by the Foundation or its designee.

(2)If Company chooses option (i) above, then it shall use Commercially Reasonable Efforts to obtain approval of such protocol and upon receipt of such approval, it shall provide such Development Candidate or Product to the Patients in accordance with the approved protocol; provided, that the parties shall engage in good faith negotiations with respect to [**].

(3)If Company chooses option (ii) above, then Company shall facilitate Foundation’s efforts to arrange for such expanded access program for such Development Candidate or Product for the Patients by taking all reasonable actions requested by Foundation, in each case [**], including without limitation: (1) either (1) allowing the expanded access program to be performed pursuant to Company’s IND (in which case Foundation or its designee shall provide Company with all data arising from and other information with respect to such expanded access program that is necessary or reasonably useful for Company to fulfill its obligations as the IND holder) or (2) providing Foundation or its designee with a right of reference to the manufacturing-related information and safety and efficacy data in Company’s IND or Drug Master File or similar regulatory filing (as applicable) so that Foundation or its designee can file its own IND with respect to such expanded access program; (ii) providing such Development Candidate or Product to an appropriate designee of Foundation for administration to the Patients in accordance with any expanded access protocol for which Foundation or its designee has obtained approval from the FDA [**]); and (iii) providing Foundation with a non-

xlii

exclusive, fully paid, sublicensable license under Company Technology and Data, and solely to the extent reasonably necessary for Foundation to exercise its rights under the foregoing license, to Company Base IP (provided, that the license granted to Foundation hereunder [**] or [**] or [**] to perform or have performed on its behalf any and all activities necessary or reasonably useful to provide such expanded access to such Drug Candidate or Product in accordance with this Second Amendment Section 13(c)(3). In connection with the foregoing, Foundation, [**], shall maintain clinical trial and/or product liability insurance, as applicable, in an amount consistent with industry standards and only if available on commercially reasonable terms, and shall [**] with respect to such insurance, with respect to losses arising out of or related to the activities contemplated under this Second Amendment Section 13(c)(3). Foundation shall provide a certificate of insurance evidencing such coverage to Company upon request.

(d)Indemnification by Foundation. In connection with the foregoing Second Amendment Sections 13(b)(3) and 13(c)(3), Foundation hereby agrees to save, defend, indemnify and hold harmless Company, its trustees, officers, employees and agents (each, a “Company Indemnitee”) from and against any and all losses, damages, liabilities, expenses and costs, including reasonable legal expenses and attorneys’ fees (“Company Losses”), to which a Company Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any Third Party to the extent such Company Losses arise directly or indirectly out of (a) [**] or [**] of any Development Candidate or Product by Foundation, its Affiliate(s) or Licensee(s) pursuant to Second Amendment Sections 13(b)(3) or 13(c)(3), or (b) the breach of this Agreement by Foundation or the gross negligence or willful misconduct of Foundation pursuant to Second Amendment Sections 13(b)(3) or 13(c)(3), except in each case to the extent such Losses result from (x) the breach of this Agreement by Company or the gross negligence or willful misconduct of any Company Indemnitee, or (y) the activities of Company or its agents or employees in connection with any Development Candidate or Product. The obligations of Foundation under this Second Amendment Section 13(d) are conditioned upon Company’s delivery of written notice to Foundation of any potential Company Losses promptly after Company becomes aware of such potential Company Losses. Foundation shall have the right to assume the defense of any suit or claim related to Company Losses if it has assumed responsibility for the suit or claim in writing. If Foundation defends the suit or claim, Company may participate in (but not control) the defense thereof at its sole cost and expense but Company may not settle such suit or claim without the prior written consent of Foundation, not to be unreasonably withheld.

(e)Clinical Trial/CRO Agreements. In connection with the foregoing Second Amendment Sections 13(b)(3) and 13(c)(3), Foundation hereby agrees that under any circumstance in which Foundation is contracting directly with clinical trial sites, clinical investigators, and contract research organizations (“CROs”), it will use as the basis for its negotiations [**], and will use Commercially Reasonable Efforts to secure terms with respect to publication, confidentiality, intellectual property (which shall be [**], as the case may be, [**]), and indemnification substantially similar to those routinely obtained by Company with respect to such an agreement, and naming the Company as a third-party beneficiary.

14.Patents. Section 6.2 of the Agreement (captioned “Patent Filings”) shall, as of the Second Amendment Effective Date, be amended and restated as follows:

xliii

“6.2.Patent Filings.

“(a)Company shall control the filing, prosecution and maintenance of all Patents on Company Technology at its sole expense, which expense shall be included as part of Company’s contribution to the Research Project and not payable or reimbursable by Foundation; provided, that Foundation shall have reasonable rights of comment and consultation on all such filing, prosecution and maintenance activities; and provided further that with respect to initial filings claiming the composition of matter, method of use, or process for manufacturing small molecules, Foundation’s review shall be confined to specific individuals reasonably acceptable to Company.

“(b)Subject to the prior written consent of Foundation, such consent not to be unreasonably withheld, delayed or conditioned, Company shall have the right to disclose, in connection with the filing, prosecution or maintenance of any Patents on Company Technology filed by it pursuant to this Agreement, any Confidential Information to the extent reasonably necessary to support and enable the claims of any application with respect to such Patents, or to maintain or enforce any such issued Patents. If, with respect to a specific filing or other document to be submitted to a governmental or quasi-governmental authority in connection with an issued Patent or application for a Patent, Foundation has reviewed and commented on such filing or document pursuant to Section 6.2(a) of the Agreement and raised no objections to the use of Confidential Information, then such consent will be deemed to have been granted for such filing or document.

“(c)Notwithstanding the foregoing Sections 6.2(a) and 6.2(b) of the Agreement, if Company grants the Reversionary License to Foundation pursuant to Section 6.1(c)(2) of the Agreement with respect to a Reversion Candidate or Reversion Product, then Foundation (or its designee) shall have the rights and obligations of Company under Sections 6.2(a) and 6.2(b) of the Agreement (substituting “Foundation” for “Company” as the context requires) with respect to Patents exclusively licensed to Foundation pursuant to such Reversionary License; provided, however, that [**], and [**] of the Agreement.

“(d)Each of Company and Foundation shall execute all papers and instruments, and require its employees and contractors to execute all papers and instruments, so as to enable the other party to exercise the rights set forth in this Section 6.2 of the Agreement.”

15.Confidentiality and Exceptions. Section 5.1 of the Agreement (captioned “Confidentiality”) and Section 5.2 of the Agreement (captioned “Exceptions”) shall, as of the Second Amendment Effective Date, be amended and restated as follows:

“5.1Confidentiality. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the parties, the parties agree that, during the Term and for a period of [**] years thereafter, each party (the “Receiving Party”) will maintain in confidence all Confidential Information disclosed to it by the other party (the “Disclosing Party”), provided that, with regard to Confidential Information which is trade secret information, such obligation shall extend thereafter until such information is

xliv

no longer a trade secret of the Disclosing Party. The Receiving Party may use the Confidential Information of the Disclosing Party only to the extent required to accomplish the purposes of this Agreement. The Receiving Party shall use at least the same standard of care as it uses to protect proprietary or confidential information of its own to ensure that its employees, agents, consultants and other representatives do not disclose or make any unauthorized use of the Disclosing Party’s Confidential Information; provided, however, each party shall ensure that any such employees, agents, consultants and other representatives who are granted access to trade secrets or, prior to publication, to other potentially patentable matter for which patent protection has been or is planned to be sought, arising from the DC Research shall sign written agreements containing confidentiality obligations substantially similar to those set forth in this Agreement except that the duration of such confidentiality obligations for consultants may be less than the duration set forth in this Agreement provided that the duration shall be for a minimum of [**] years from the date of disclosure. Each party will promptly notify the other upon discovery of any unauthorized use or disclosure of the other party’s Confidential Information.

“5.2Exceptions. The obligations of non-disclosure and non-use contained in Section 5.1 will not apply to the extent that it can be established by the Receiving Party by competent proof that such Confidential Information: (a) was already known to the Receiving Party, other than under an obligation of confidentiality, at the time of disclosure by the Disclosing Party; (b) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the Receiving Party; (c) became generally available to the public or otherwise part of the public domain after its disclosure and other than through any act or omission of the Receiving Party in breach of this Agreement; (d) is independently discovered or developed by the Receiving Party without the use of Confidential Information of the Disclosing Party; or (e) was disclosed to the Receiving Party, other than under an obligation of confidentiality, by a Third Party who had no obligation to the Disclosing Party not to disclose such information to others.”

16.Publications, Presentations and Public Disclosures. Section 5.4 of the Agreement (captioned “Publication”) and Section 5.5 of the Agreement (captioned “Publicity; Regulatory Disclosures”) shall, as of the Second Amendment Effective Date, be amended and restated as follows:

“5.4.Scientific and Medical Publications and Presentations.

“(a)Company and Foundation each acknowledge the other party’s interest in publishing or presenting certain results of the Research (including but not limited to the DC Research) to obtain recognition within the scientific community and to advance the state of scientific knowledge and enhance the progress of research in the Field, in all cases in a manner consistent with existing obligations to Third Parties and scientific and industry standards for the research, development and commercialization of small molecules for the treatment, mitigation or prevention of disease. Each party also recognizes their mutual interest in obtaining Patents in support of Products, and the need for such publications or presentations to be strictly monitored to prevent any adverse

xlv

effect from premature publication or dissemination of results of the activities hereunder. Consequently, the JSC shall establish reasonable policies and procedures with respect to scientific publications and presentations that balance the foregoing interests, and once established both parties shall be bound by such policies and procedures, and may establish a separate publication committee to administer such policies and procedures. In the event no such procedures and policies are established by the JSC, either party, its employees or consultants wishing to make a publication in a scientific or medical journal or a presentation or similar oral disclosure made at a scientific or medical conference without obligation of confidentiality relating to work performed as part of the Research (the “Publishing Party”) shall transmit to the other party (the “Reviewing Party”) a copy of the proposed written publication or a written detailed description of the proposed oral disclosure at least [**] days prior to submission or disclosure (or, in the case of Third Party agreements, such shorter period as required by such Third Party agreement) prior to submission for publication or presentation. The Reviewing Party shall have the right (a) to make modifications to the publication for accuracy or intellectual property reasons, and (b) to obtain a delay in publication or presentation of up to [**] days (or, in the case of Third Party agreements, such shorter period as required by such Third Party agreement) in order to enable patent applications or similar applications protecting rights in such information to be filed, and each party shall have the right to prohibit disclosure of any of its Confidential Information (except as otherwise provided in Section 6.2 of the Agreement) in any such proposed publication or presentation. Notwithstanding the foregoing, in no event shall any publication, presentation, or other public disclosure disclose the chemical structure of any Lead Candidate, Drug Candidate, Development Candidate, or Product absent specific permission from the JSC. In any permitted publication or presentation by a party, the other party’s contribution shall be duly recognized, and authorship shall be determined in accordance with customary practice in the scientific or medical field.

(b)Company shall provide in each Research Report a summary section which is suitable for immediate public disclosure and the Foundation may release copies of such portions of each Research Report and supporting Data other than chemical structures to any Third Party investigator who requests such material from the Foundation in writing; provided, however, that said Third Party investigator first executes Company’s non-disclosure agreement that the Company provides to the Foundation for such purpose (it being understood that such non-disclosure agreement will not prohibit said Third Party investigator from applying his or her knowledge of the Data to further SMA research and/or to treatment of SMA patients, but will prohibit him or her from transferring such Data except as incidental and necessary to treating SMA patients).

(c)The parties acknowledge that during the course of research, development and commercialization of Products, it may be necessary to enter into agreements with Third Parties that require different standards for publication and presentation of research results relating to the Research. Notwithstanding Section 5.4(a) of the Agreement, the party conducting research, development or commercialization of Products may enter into agreements with academic, government, nonprofit or similar entities which allow principal investigators and other external researchers to publish or present the results of

xlvi

their research on terms inconsistent with Section 5.4(a) of the Agreement; provided, that each party entering into such agreements shall use Commercially Reasonable Efforts to include provisions reasonably consistent with and similar to those appearing in Section 5.4(a) of the Agreement in such Third Party agreements.

“5.5Publicity; Regulatory Disclosures. In connection with the execution of the Second Amendment, the parties shall jointly issue one or more press releases, the contents of which shall be mutually agreed. Except as otherwise required by law or regulation, or as permitted pursuant to Section 5.4 of the Agreement, neither party shall issue any additional press release or make any other public disclosure concerning this Agreement or the subject matter hereof without first providing the other party with a copy of the proposed release or public disclosure for review and comment, provided that such right of review and comment shall only apply for the first time that specific information is to be disclosed, and shall not apply to the subsequent disclosure of substantially similar information that has previously been disclosed. The party proposing to make the press release or other public disclosure shall give due consideration to any reasonable comments by the other party relating to such proposed press release or other public disclosure. The principles to be observed by the parties in press releases or other public disclosures with respect to this Agreement shall be: accuracy, compliance with applicable legal and regulatory requirements, the requirements of confidentiality under this Agreement and customary business practice in the biopharmaceutical industry for disclosures by companies comparable to Company. For the avoidance of doubt, either party may issue such press releases as it determines, based on advice of counsel, are reasonably necessary to comply with laws or regulations (including regulations of non-governmental regulatory bodies) or for appropriate market disclosure. It is understood, however, that unless required by law or regulation, the parties shall not disclose the specific financial terms and conditions of this Agreement in any press release or other public disclosure. In addition, if a public disclosure is required by law or regulation, including without limitation in a filing with the United States Securities and Exchange Commission, the disclosing party shall provide copies of the proposed disclosure reasonably in advance of such filing or other disclosure for the non-disclosing party’s prior review and comment and shall give due consideration to any reasonable comments by the non-filing party relating to such filing, including without limitation the provisions of this Agreement for which confidential treatment should be sought.”

00.Xxxxxxxx Arbitration.

(a)An arbitration under this Second Amendment Section 17 (a “Baseball Arbitration”) shall be initiated by written notice of one party to the other and may only be initiated with respect to disputes which meet both the following criteria: (i) the dispute arises from matters within the jurisdiction of the JSC following escalation to the respective Chief Executive Officers of the parties as provided elsewhere in the Agreement, and (ii) Baseball Arbitration is explicitly specified as the method for resolving such dispute pursuant to the Agreement.

xlvii

(b)The Baseball Arbitration shall be held in a location mutually agreeable to the parties, or if no such location can be agreed, in New York City, according to the then-current commercial arbitration rules of the American Arbitration Association (“AAA”), except to the extent such rules are inconsistent with this Second Amendment Section 17.

(c)The Baseball Arbitration will be conducted by one (1) arbitrator who shall be reasonably acceptable to the parties and who shall be appointed in accordance with AAA rules. If the parties are unable to select an arbitrator within [**] days of the notice that initiated the Baseball Arbitration, then the arbitrator shall be appointed in accordance with AAA rules. Any arbitrator chosen hereunder shall have educational training and industry experience sufficient to demonstrate a reasonable level of scientific, financial, medical and industry knowledge relevant to the particular dispute.

(d)Within [**] days after the selection of the arbitrator, each party shall submit to the arbitrator and the other party a proposed resolution of the dispute that is the subject of the arbitration, together with any relevant evidence in support thereof (the “Proposals”). Within [**] business days after the delivery of the last Proposal to the arbitrator, each party may submit a written rebuttal of the other party’s Proposal and may also amend and re-submit its original Proposal. The parties and the arbitrator shall meet within [**] business days after the parties have submitted their final Proposals (and rebuttals, if any), at which time each party shall have [**] to argue in support of its Proposal. The parties shall [**]. Within [**] days after such meeting, the arbitrator shall select one of the final Proposals so submitted by one of the parties as the resolution of the dispute, but may not alter the terms of either final Proposal and may not resolve the dispute in a manner other than by selection of one of the submitted final Proposals. If a party fails to submit a Proposal within the initial [**] day time frame set forth in the first sentence of this Second Amendment Section 17, the arbitrator shall select the Proposal of the other party as the resolution of the dispute. Any time period set forth in this Second Amendment Section 17 may be extended by mutual agreement of the parties.

(e)No arbitrator shall have the power to award punitive damages under this Agreement regardless of whether any such damages are contained in a Proposal, and such award is expressly prohibited. The proceedings and decisions of the arbitrator shall be confidential, final and binding on the parties. Judgment on the award so rendered may be entered in a court having jurisdiction thereof.

(f)[**] the costs of such Baseball Arbitration.

18.Miscellaneous.

(a)Compounds not Selected: During the Second Amendment Term and for the [**] period thereafter, should Company require additional funds for the conduct of research or Development in the Field of any Lead Candidate that was tested in the course of the DC Research but was not selected as a Reversion Candidate (such research and Development, “Non-DC Research”), Foundation will be consulted and provided the opportunity to fund such Non-DC Research in whole or in part prior to any fundraising efforts for such Non-DC Research. Should Company identify an opportunity for agreement with any Third Party or Third Parties with respect to such Non-DC Research during such [**] period, it will provide reasonable advance

notice to Foundation, and the parties will negotiate in good faith (involving such Third Party or Third Parties as appropriate) to develop a structure that supports such additional funding, based on the following principles: (a) entities co-funding such Non-DC Research should share information on the Non-DC Research with each other, subject to appropriate confidentiality provisions, (b) governance with respect to co-funded Non-DC Research should be via a joint steering committee including representatives of Foundation, Company, and any Third Parties, and (c) entities that have provided funding to such co-funded Non-DC Research should have an opportunity (subject to compliance with the terms of their respective funding agreements) to continue their support of such Non-DC Research. For clarity, Company’s obligations under this Second Amendment Section 18(a) shall in no way limit Company’s ability to engage in general fund-raising activities and to enter into agreements relating thereto.

(b)Additional Testing of Reversion Candidates. After the end of the Research Term and selection of one or more Development Candidates, the JSC (at the request of either party) shall consider whether further research or pre-clinical Development on any Reversion Candidate that is not a Development Candidate is advisable for the purposes of enhancing the utility of such Reversion Candidate as a potential back-up compound or next-generation Product. If deemed advisable by the JSC, and subject to agreement between the parties with respect to funding, Company shall make such Reversion Candidates available for such further research or pre-clinical Development under the terms of a commercially reasonable materials transfer agreement (or a more comprehensive agreement agreed by the parties with respect to such Third Party, which shall include commercially reasonable terms with respect to materials transfer).Without limiting the generality of the foregoing, each such materials transfer agreement shall provide that in no event shall any compound become the property of such Third Party, nor shall any such compound become subject to royalty or other reach-through payment obligations to such Third Party as a result of such testing by such Third Party, and shall also require that a summary of the results of the research be provided to the Company. Company shall share all such research results with the JSC.

(c)Testing by Foundation Partners. Upon the Foundation’s request, and under the supervision of the JSC with respect to design of the testing to be done and selection of appropriate compounds and (only during the Research Term) consistent with the then-current Research Plan, Company shall provide reasonable quantities of compounds synthesized or tested during the DC Research (“Research Compounds”) to other Foundation partners for testing on a blinded basis in assays already being run by such Foundation partner, provided that (i) after the end of the Research Term, such testing shall be limited to Reversion Candidates and shall not include, without the prior written consent of Company, any Development Candidate that is, at such time, the subject of a Company Clinical Trial, (ii) the Foundation or such Foundation partner shall disclose the results of such screening to Company and (iii) such testing shall be performed pursuant to a separate materials transfer agreement reasonably acceptable to Company and negotiated in good faith by the parties prior to provision of any Research Compounds or related information, which agreement shall contain reasonable and customary terms to protect the parties’ respective intellectual property rights. Without limiting the generality of the foregoing, each such materials transfer agreement shall provide that in no event shall any Research Compound become the property of the Foundation partner, nor shall any Research Compound become subject to royalty or other reach-through payment obligations to the

xlix

Foundation partner as a result of such testing by such Foundation partner, and shall also require that a summary of the results of the research be provided to the Foundation. Foundation shall share all such research results with the JSC on a regular basis.

(d)Financial Reporting. For so long as it is not a publicly-traded company, (i) Company shall provide Foundation, within [**] days after the end of each of the first three quarters of the fiscal year of the Company, with a copy of the financial report for such quarter that Company generates for its investors, and (ii) Company shall use best its efforts to provide within [**] days, but in no event more than [**] days, after the end of the fiscal year of the Company, a copy of the annual audit report for such year that the Company generates for its investors.

[**], Company may request Foundation consider amending the provisions of this Second Amendment Section 18(d), and Foundation shall consider such request in good faith.

(e)Representations, Warranties and Covenants. Each party hereby represents, warrants and covenants to the other that (i) it has the authority and right to enter into this Second Amendment and to perform its obligations hereunder and (ii) it has not granted as of the Second Amendment Effective Date, and will not grant during the Term (except as specifically allowed and consistent with the applicable terms of this Agreement), any assignment, license, covenant not to sue, option to obtain a license or other right, interest or benefit, exclusive or otherwise, to any Third Party relating to the DC Research or any Reversion Candidate, Drug Candidate, Development Candidate or Product that conflicts with or limits the rights granted to or exercisable by the other party hereunder.

(f)Designation of Third Party Representatives. In any case under this Agreement under which Foundation is entitled to designate a representative, such representative may be a person other than a Foundation employee provided the following criteria are met: (i) Foundation identifies such person in writing to Company, [**], and requests Company’s written consent for such addition, such consent not to be unreasonably withheld or delayed and to be based solely on objective written criteria determined by the JSC within [**] months after the Second Amendment Effective Date, which criteria shall vary depending upon the information to which such person is anticipated to have access to in the course of his or her service as such representative; and (ii) such person signs a confidentiality agreement with Company substantially in the form attached as Exhibit SA-7. The JSC shall also establish policies and procedures regarding continuing disclosure obligations for such representatives with respect to conflicts of interest within [**] months of the Second Amendment Effective Date. A breach by a designated representative of Foundation of such conflict of interest policies, or of the confidentiality agreement between Company and such representative, shall entitle Company to terminate such representative effective upon written notice by Company to Foundation stating the grounds for such termination.

AMENDMENT No. 3 TO SPONSORED RESEARCH AGREEMENT

This third amendment (“Third Amendment”) to the Sponsored Research Agreement is effective as of the 1st day of January, 2011 (the “Third Amendment Effective Date”), by and between Spinal Muscular Atrophy Foundation (the “Foundation”) and PTC Therapeutics, Inc. (the “Company”), with reference to the following facts and circumstances.

WHEREAS Foundation and Company are parties to that certain Sponsored Research Agreement (the “Agreement”) dated as of June 1st, 2006, as amended by the First Amendment on October 12th, 2007 and by the Second Amendment on May 1, 2009 (the “Second Amendment”);

WHEREAS, the parties desire to further amend the Agreement in connection with continued research, beyond the [**] specified in the Second Amendment, on small molecule therapeutics for SMA;

NOW THEREFORE, in consideration of the premises and mutual covenants contained in this Third Amendment, the parties agree as follows:

1.Continuing Research.

(a)By letter dated [**], Foundation called a special meeting of the JSC pursuant to Second Amendment Section 2(g) to address the Cost/Timeline Issue that a [**] by the [**] of [**] and that the [**] of $[**] before a [**] would be [**]. As contemplated by Second Amendment Section 2(g)(1) the JSC has agreed upon the Corrective Plan and related budget that are attached as Exhibits TA-1 and TA-2, respectively. Such Corrective Plan and related budget constitutes an amendment of the Research Plan and related budget. Company shall conduct the DC Research in accordance with the Agreement, as amended.

(b)In connection with adoption of the Corrective Plan, the JSC has also agreed upon the DC Criteria attached as Exhibit TA-3 and the parties have agreed to extend the DC Timeline Goal to [**] and the Research Term until the earliest of (i) the date upon which the JSC first designates a Development Candidate, (ii) [**] or (iii) the effective date of any termination of the Research Term pursuant to Second Amendment Section 3. If a Development Candidate is not selected by the extended DC Timeline Goal, the parties shall have the right to call a special meeting of the JSC to address [**] in accordance with Second Amendment Section [**], including by agreeing upon [**], and if applicable thereafter, the rights specified in Section Amendment Section 2(h) and/or Second Amendment Section [**].

(c)Notwithstanding Second Amendment Section 2(d), Company shall be responsible for funding one hundred percent (100%) of the total overall cost of all DC Research performed on or after the Third Amendment Effective Date; provided, however, that Company shall have the ability to set its own budgets with respect to the conduct of the research after [**] so long as the Company’s obligations under Section 2.5 of the Agreement (captioned “Performance Standards”) are met. Company acknowledges and agrees that Foundation has paid all amounts due to Company pursuant to Second Amendment Section 2(d) and does not have any further

obligation to reimburse Company for any amounts incurred by Company, whether before or after the Third Amendment Effective Date, with respect to the DC Research. If Foundation decides in its discretion to engage [**] or other external contract research organizations (“CROs”) or academic collaborators [**] to test, after the Third Amendment Effective Date, any compounds arising from the DC Research, Foundation shall be solely responsible for paying any amounts owed to [**] or such other CROs or academic collaborators in connection with such testing.

2.Governance. Second Amendment Section 5(d) is amended and restated in its entirety as follows:

“(d)Meetings and Decision-Making by the JSC — Before Proof-of-Concept. During the Research Term and through achievement of Proof-of-Concept, the JSC shall meet periodically as needed, but in no event less than [**], in person (with the location to be at Foundation’s offices in New York City unless otherwise agreed by the Parties) or by teleconference or other electronic means as mutually agreed, to discuss matters within its jurisdiction. In addition, the JSC may agree to hold special meetings at any time on reasonable notice given by the chairperson or the secretary to the other members of the JSC. Unless waived by a party in writing, at least [**] JSC representatives of each party must participate in a meeting of the JSC in order for there to be a quorum at such meeting. The members of the JSC shall seek to make all determinations to be made by them unanimously following full discussion thereof (with each party’s representatives having, collectively, one (1) vote). If the JSC is unable to reach a unanimous decision on any matter within its jurisdiction, the parties’ respective Chief Executive Officers shall meet in person to attempt to resolve the matter in good faith. If the parties’ respective Chief Executive Officers are unable to reach agreement on a matter referred to them pursuant to the foregoing sentence within [**] days after the matter referral, then either party may by written notice to the other submit the matter to Baseball Arbitration as provided in Section 17 of this Second Amendment; provided, however, that the following matters shall not be subject to such referral to Baseball Arbitration, : (i) [**]; (ii) any [**] described in Second Amendment Section [**] as [**] to or [**]; (iii) any changes to [**] for the [**] that would require [**] than contemplated in [**]; (iv) deciding whether to pursue [**] of this Second Amendment in the event of a [**]; and (v) any disputes referred to the CEOs pursuant to Second Amendment Section [**]. Disputes not subject to referral to Baseball Arbitration pursuant clauses (i) through (v) of the preceding sentence shall be resolved as follows: any dispute arising in the JSC with respect to clause (v) shall be decided by [**], and any disputes arising in the JSC with respect to clauses (i) through (iv) may only be resolved by mutual agreement of the parties.”

3.Partnering Activities.

Second Amendment Section 10(c) is amended and restated in its entirety as follows:

“(c)If Company determines to actively pursue Collaboration Activities, whether at its own initiative or in response to inquiries from Third Parties, Company will first seek input from Foundation through a mutually-agreed team of Foundation representatives

(the “Foundation Partnering Team”) on the nature, scope, and potential terms of a transaction arising in connection with such Collaboration Activities, as well as a rank-ordered summary list of preferred potential counterparties to such transaction. To the extent prepared by Company rather than received by Company from a potential counterparty, Company shall also provide the Foundation Partnering Team with an opportunity to review a draft term sheet and related materials in support of its proposed Collaboration Activities. The Foundation shall collect input from the Foundation Partnering Team on Company’s overall approach to Collaboration Activities, as well as specific input on any term sheet or related materials provided to the Foundation Partnering Team, and shall promptly provide such input to Company. The initial mutually-agreed members of the Foundation Partnering Team are set forth on Exhibit TA-4. The Foundation may replace the outside counsel member of the Foundation Partnering Team with an alternative outside counsel chosen by the Foundation; such replacement will be effective upon notice to Company. The Foundation may replace any other member of the Foundation Partnering Team with an alternative individual chosen by the Foundation; such replacement will be effective upon PTC’s written consent, which will not be unreasonably withheld or delayed.”

Second Amendment Section 10(e) is amended and restated in its entirety as follows:

“(e)Prior to Company entering into a definitive written agreement with any Third Party in connection with Collaboration Activities, Company shall seek the review and approval of the Foundation by providing the members of the Foundation Partnering Team with a proposed final draft of the definitive written agreement, a summary (which may be oral or written) of the proposed transaction, including an overview of any items or terms subject to finalization in the draft provided, and the timely opportunity (which may include one or more in-person meetings) to discuss such draft and summary and answer the Foundation’s questions with respect thereto. If required by the Company’s confidentiality agreement with the potential counterparty, Company shall have the right to redact financial terms from such proposed final draft of the definitive written agreement. As promptly as reasonably possible, but in no event later then [**] business days following receipt by the Foundation Partnering Team members of such proposed final draft of the definitive written agreement and summary, Foundation shall either approve or deny such proposed transaction; provided, however, that if Company has otherwise complied with requirements of this Second Amendment Section 10, Foundation shall only be entitled to deny such proposed transaction if it agrees either (i) to fund [**] percent ([**]%) of ongoing Development and commercialization costs for the applicable Development Candidate(s) or Product(s), or (ii) [**] or [**] and any related rights pursuant to [**]; and provided further, that failure of Foundation to communicate its approval or denial of a transaction pursuant to Second Amendment Section 10(e) shall entitle PTC to treat the proposed transaction as approved by Foundation. If the Foundation denies approval in accordance with this Second Amendment Section 10(e), Company shall not enter into such proposed definitive written agreement, but shall have the right to continue the applicable negotiations consistent with

this Second Amendment Section 10 for the purposes of achieving a form of such definitive written agreement acceptable to Foundation.”

0.Xx Other Modifications. In all other respects, the terms and conditions of the Agreement shall remain unchanged and in full force and effect. In the event of any conflict between the terms of this Third Amendment and the terms of the Agreement, the First Amendment, or the Second Amendment, the terms of this Third Amendment shall govern. For clarity, any cross-references to Agreement Sections refer to those Agreement Sections as amended by this Third Amendment.

IN WITNESS WHEREOF, the parties have executed this Third Amendment by their duly authorized officers as of the date set forth above.
