BACKGROUND

In the course of conducting biomedical and behavioral research, the IC investigators made inventions that may have commercial applicability.

By assignment of rights from the IC employees, HHS, on behalf of the Government, and together with Association Institute de Myologie (AIM, Paris, FR), Centre National de la Recherche Scientifique (CNRS, Paris, FR), Universite Pierre et Marie Curie (UPMC, Paris, FR), and INSERM TRANSFERT SA (Paris, FR) (together “Co-Owner”) owns intellectual property rights claimed in any United States or foreign patent applications or patents corresponding to the assigned inventions. HHS also owns any tangible embodiments of these inventions actually reduced to practice by the IC.

The Secretary of HHS has delegated to the IC the authority to enter into this Agreement for the licensing of rights to these inventions under 35 U.S.C. §§200-212, the Federal Technology Transfer Act of 1986, 15 U.S.C. §3710(a), and the regulations governing the licensing of Government-owned inventions, 37 CFR Part 404.

The IC desires to transfer these inventions to the private sector through commercialization licenses to facilitate the commercial development of products and processes for public use and benefit.

The Licensee desires to acquire commercialization rights to certain of these inventions in order to develop processes, methods, or marketable products for public use and benefit.

GRANT OF RIGHTS

The IC hereby grants, and the Licensee accepts, subject to the terms and conditions of this Agreement, a nonexclusive license under the Licensed Patent Rights in the Licensed Territory to make and have made, research, have researched, to use and have used, to sell and have sold, to offer to sell, and to import any Licensed Products in the Licensed Fields of Use and to practice and have practiced any Licensed Processes in the Licensed Fields of Use.

If the license granted to Licensee in Paragraph 3.1 is held to be invalid or otherwise ineffective with respect to any of the Licensed Patent Rights on account of any failure by the IC to obtain the consent of a co-owner of such Licensed Patent Rights to the grant of such license, the IC hereby covenants not to enforce such Licensed Patent Rights against Licensee or any of Licensee’s permitted sublicensees based on any making or having made, research, having researched, use or having used, sale or having sold, offering to sell, or importation of any Licensed Products in the Licensed Fields of Use or practice or having practiced any Licensed Processes in the Licensed Fields of Use by or on behalf of Licensee or any of Licensee’s permitted sublicensees, for so long as this Agreement remains in force, and the IC further covenants not to consent or agree to, and not to grant or transfer any right permitting or enabling the undertaking of, any such enforcement by any third party.

Licensee understands that, as of the date of this Agreement, NIH and/or IC, on the one hand, and the Co-Owner, on the other hand, are or may be in discussions regarding a proposed inter-institutional agreement (the “Proposed IIA”) between them pursuant to which they may enter into certain agreements regarding the licensing and administration of the Licensed Patent Rights. Licensee agrees, if requested by NIH and/or IC, to reasonably negotiate appropriate amendments to this Agreement to conform with the Proposed IIA, if and when executed, and, whether or not the Proposed IIA is executed, shall agree to pay any portion of Licensee’s reimbursement obligations under Paragraphs 6.9 and 6.10 directly to Co-Owner as directed by the IC, provided that Licensee’s license hereunder shall remain in force and Licensee shall be treated on par with (or more favorably than) other non-exclusive licensees of the Licensed Patent Rights.

This Agreement confers no license or rights by implication, estoppel, or otherwise under any patent applications or patents of the IC other than the Licensed Patent Rights regardless of whether these patents a redominant or subordinate to the Licensed Patent Rights.

SUBLICENSING

The Licensee shall notify the IC in writing of its intent to sublicense, after which Licensee may enter into sublicensing agreements under the Licensed Patent Rights only when it concurrently licenses proprietary or in-licensed intellectual property rights controlled by Licensee in connection with Licensed Products or Licensed Processes. For the avoidance of doubt, the Licensee does not have the right to solely sublicense the Licensed Patent Rights.

The Licensee agrees that any sublicenses granted by it shall provide that the obligations to the IC of paragraphs 5.1, 5.2, 8.1, 10.1, 10.2, 12.5, and 13.7-13.9 of this Agreement shall be binding upon the sublicensee as if it were a party to this Agreement. The Licensee further agrees to attach copies of these Paragraphs to all sub license agreements.

Any sublicenses granted by the Licensee shall provide for the termination of the sub license, or the conversion to a license directly between the sublicensees and the IC, at the option of the sublicensee, upon termination of this Agreement under Article 13. This conversion is subject to the IC approval and contingent upon acceptance by the sublicensee of the remaining provisions of this Agreement.

The Licensee agrees to forward to the IC a complete copy of each fully executed sublicense agreement postmarked within [**] of the execution of the agreement, which copy may be reasonably redacted as to confidential business information that is not required to enable the IC to confirm the compliance of the a sublicense agreement with the requirements of this Agreement. To the extent permitted by law, the IC agrees to maintain each sublicense agreement in confidence.

STATUTORY AND NIH REQUIREMENTS AND RESERVED GOVERNMENT RIGHTS

Prior to the First Commercial Sale, the Licensee agrees to provide the IC with reasonable quantities of Licensed Products or materials made through the Licensed Processes for the IC’s non-clinical research use.

The Licensee agrees that products used or sold in the United States embodying Licensed Products or produced through use of Licensed Processes shall be manufactured substantially in the United States, unless a written waiver is obtained in advance from the IC.

ROYALTIES AND REIMBURSEMENT

The Licensee agrees to pay the IC a noncreditable, nonrefundable license issue royalty as set forth in Appendix C.

The Licensee agrees to pay the IC a minimum annual royalty as set forth in Appendix C.

The Licensee agrees to pay the IC earned royalties as set forth in Appendix C.

The Licensee agrees to pay the IC benchmark royalties as set forth in Appendix C.

The Licensee agrees to pay the IC sublicensing royalties as set forth in Appendix C.

A patent or patent application licensed under this Agreement shall cease to fall within the Licensed Patent Rights for the purpose of computing earned royalty payments in any given country on the earliest of the dates that:

the application has been abandoned and not continued;

the patent expires or irrevocably lapses; or

the patent has been held to be invalid or unenforceable by an unappealed or unappealable decision of a court of competent jurisdiction or administrative agency.

No multiple royalties shall be payable because any Licensed Products or Licensed Processes are covered by more than one of the Licensed Patent Rights.

On sales of Licensed Products by the Licensee to sublicensees or on sales made in other than an arms-length transaction, the value of the Net Sales attributed under this Article 6 to this transaction shall be that which is received in a subsequent arms-length transaction from an end-user of the Licensed Products.

With regard to unreimbursed expenses associated with the preparation filing, prosecution, and maintenance of all patent applications and patents included within the Licensed Patent Rights and paid by the IC and the Co-Owner prior to the effective date of this Agreement, the Licensee shall pay the Co-Owner, as an additional royalty, within [**] of the Co-Owner’s submission of a statement (which will include summaries of patent prosecution invoices) and request for payment to the Licensee, an amount equivalent to the unreimbursed patent expenses previously paid by the IC and the Co-Owner divided by the aggregate number of commercial licensees of the Licensed Patent Rights, that are obligated to reimburse patent costs under similar such provision on the date of the Invoice. Notwithstanding, Licensee shall not be required to pay more than [**] of such expenses. Such expenses are estimated to total [**] Euro ([**] US Dollars with an exchange rate of 1.07 US Dollar to Euro) as of January 18, 2017, and accordingly the Licensee’s payment obligation as of January 18, 2017 is estimated to be [**] Euro ([**] US Dollars). The conversion to US Dollars, if applicable, shall be made using the exchange rate published on the day the statement is received by Licensee. Unless otherwise indicated in Co-Owner’s request for payment, Licensee shall wire its payment obligation under Paragraph 6.9 to the following bank account:

With regard to unreimbursed expenses associated with the preparation, filing, prosecution, and maintenance of all patent applications and patents included within the Licensed Patent Rights and paid by the IC and the Co-Owner on or after the effective date of this Agreement, the IC, at its sole option, may require the Licensee:

to pay the Co-Owner on an annual basis, within [**] of the Co-Owner’s submission of a statement (which will include summaries of patent prosecution invoices) and request for payment, a royalty amount equivalent to these unreimbursed expenses paid during the previous calendar year(s) divided by the aggregate number of commercial licensees of the Licensed Patent Rights, that are obligated to reimburse patent costs under similar such provision on the date of the Invoice;

to pay these unreimbursed expenses directly to the law firm employed by the IC or the Co-Owner, as applicable, to handle these functions divided by the aggregate number of commercial licensees of the Licensed Patent Rights, that are obligated to reimburse patent costs under similar such provision on the date of the Invoice. However, in this event, the IC or the Co-Owner, as applicable, and not the Licensee shall be the client of the law firm; or

under exceptional circumstances, the Licensee may be given the right to assume responsibility for the preparation, filing, prosecution, or maintenance of any patent application or patent included with the Licensed Patent Rights. In that event, the Licensee shall directly pay the attorneys or agents engaged to prepare, file, prosecute, or maintain these patent applications or patents and shall provide the IC with copies of each invoice associated with these services as well as Co-Owner documentation that these invoices have been paid.

The Licensee may elect to surrender its rights in any country of the Licensed Territory under any of the Licensed Patent Rights upon [**] written notice to the IC and owe no payment obligation under Paragraph 6.3, 6.4 or 6.10 in that country after the effective date of the written notice.

PATENT FILING, PROSECUTION, AND MAINTENANCE

RECORD KEEPING

REPORTS ON PROGRESS, BENCHMARKS, SALES, AND PAYMENTS

Prior to signing this Agreement, the Licensee has provided the IC with the Commercial Development Plan in Appendix E, under which the Licensee intends to bring the subject matter of the Licensed Patent Rights to the point of Practical Application. This Commercial Development Plan is hereby incorporated by reference into this Agreement. Based on this plan, performance Benchmarks are determined as specified in Appendix D.

The Licensee shall provide written annual reports on its product development progress or efforts to commercialize under the Commercial Development Plan for each of the Licensed Fields of Use within [**] after December 31 of each calendar year. These progress reports shall include, but not be limited to: progress on research and development, status of applications for regulatory approvals, manufacture and status of sublicensing, marketing, importing, and sales during the preceding calendar year, as well as, plans for the present calendar year. The IC also encourages these reports to include information on any of the Licensee’s public service activities that relate to the Licensed Patent Rights. If reported progress differs from that projected in the Commercial Development Plan and Benchmarks, the Licensee shall explain the reasons for such

The Licensee shall report to the IC the dates for achieving Benchmarks specified in Appendix D and the First Commercial Sale in each country in the Licensed Territory within [**] of such occurrences.

The Licensee shall submit to the IC, within [**] after each calendar [**], a royalty report, as described in the example in Appendix F, setting forth for the preceding [**] period, to the extent possible, an estimate of the amount of the Licensed Products sold or Licensed Processes practiced by or on behalf of the Licensee in each country with in the Licensed Territory, the Net Sales and the amount of royalty accordingly due. With each royalty report, the Licensee shall submit payment of earned royalties due. If no earned royalties are due to the IC for any reporting period, the written report shall so state. The royalty report shall be certified as correct by an authorized officer of the Licensee and shall include a detailed listing of all deductions made under Paragraph 2.11 to determine Net Sales made under Article 6 to determine royalties due.

The Licensee agrees to forward [**] to the IC a copy of these reports received by the Licensee from its sublicensees during the preceding [**] period as shall be pertinent to a royalty accounting to the IC by the Licensee for activities under the sublicense.

Royalties due under Article 6 shall be paid in U.S. dollars and payment options are listed in Appendix G. For conversion of foreign currency to U.S. dollars, the conversion rate shall be the New York foreign exchange rate quoted in The Wall Street Journal on the day that the payment is due, and any loss of exchange, value, taxes, or other expenses incurred in the transfer or conversion to U.S. dollars shall be paid entirely by the Licensee. The royalty report required by Paragraph 9.4 shall be mailed to the IC at its address for Agreement Notices indicated on the Signature Page.

The Licensee shall be solely responsible for determining if any tax on royalty income is owed outside the United States and shall pay this tax and be responsible for all filings with appropriate agencies of foreign governments.

Additional royalties may be assessed by the IC on any payment that is more than [**] overdue at the rate of [**] percent ([**]%) per month. This [**] percent ([**]%) per month rate may be applied retroactively from the original due date until the date of receipt by the IC of the overdue payment and additional royalties. The payment of any additional royalties shall not prevent the IC from exercising any other rights it may have as a consequence of the lateness of any payment.

All plans and reports required by this Article 9 and marked “confidential” by the Licensee shall, to the extent permitted by law, be treated by the IC as commercial and financial information obtained from a person and as privileged and confidential, and any proposed disclosure of these records by the IC under the Freedom of Information Act (FOIA), 5 U.S.C. §552 shall be subject to the predisclosure notification requirements of 45 CFR §5.65(d).

PERFORMANCE

The Licensee shall use its reasonable commercial efforts to bring the Licensed Products and Licensed Processes to Practical Application. Licensee shall be deemed to have used “reasonable commercial efforts” if it has adhered to the Commercial Development Plan in Appendix E and performance of the Benchmarks in Appendix D. The efforts of a sublicensee or an Affiliate shall be considered the efforts of the Licensee.

The Licensee agrees, after its First Commercial Sale, to make reasonable quantities of Licensed Products or materials produced through the use of Licensed Processes available to patient assistance programs if commercially practicable.

The Licensee agrees, after its First Commercial Sale, and as part of its marketing and product promotion, to develop educational materials (e.g., brochures, website, etc.) directed to patients and physicians detailing the Licensed Products or medical aspects of the prophylactic and therapeutic uses of the Licensed Products, if commercially practicable and consistent with applicable regulations.

The Licensee agrees to supply, to the Mailing Address for Agreement Notices indicated on the Signature Page, the Office of Technology Transfer, NIH with a reasonable amount of inert samples of the Licensed Products or Licensed Processes or their packaging for educational and display purposes only.

INFRINGEMENT AND PATENT ENFORCEMENT

The IC and the Licensee agree to notify each other promptly of each infringement or possible infringement of the Licensed Patent Rights, as well as, any facts which may affect the validity, scope, or enforceability of the Licensed Patent Rights of which either Party becomes aware.

In the event that a declaratory judgment action alleging invalidity of any of the Licensed Patent Rights shall be brought against the IC, the IC agrees to notify the Licensee that an action alleging invalidity has been brought. The IC does not represent that it shall commence legal action to defend against a declaratory action alleging invalidity. The Licensee shall take no action to compel the Government either to initiate or to join in any declaratory judgment action. Should the Government be made a party to any suit by motion or any other action of the Licensee, the Licensee shall reimburse the Government for any costs, expenses, or fees, which the Government incurs as a result of the motion or other action. Upon the Licensee’s payment of all costs incurred by the Government as a result of the Licensee’s joinder motion or other action, these actions by the Licensee shall not be considered a default in the performance of any material obligation under this Agreement.

NEGATION OF WARRANTIES AND INDEMNIFICATION

The IC offers no warranties other than those specified in Article 1.

The IC does not warrant the validity of the Licensed Patent Rights and makes no representations whatsoever with regard to the scope of the Licensed Patent Rights, or that the Licensed Patent Rights may be exploited without infringing other patents or other intellectual property rights of third parties.

THE IC MAKES NO WARRANTIES, EXPRESSED OR IMPLIED, OF MERCHANTABILITY OR FITNESS FOR AP ARTICULAR PURPOSE OF ANY SUBJECT MATIER DEFINED BY THE CLAIMS OF THE LICENSED PATENT RIGHTS OR TANGIBLE MATERIALS RELATED THERETO.

The IC does not represent that it shall commence legal actions against third parties infringing the Licensed Patent Rights.

The Licensee shall indemnify and hold the IC, its employees, students, fellows, agents, and consultants harmless from and against all liability, demands, damages, expenses, and losses, including but not limited to death, personal injury, illness, or property damage in connection with or arising out of:

the use by or on behalf of the Licensee, its sublicensees, its directors, employees, or third parties of any Licensed Patent Rights; or

the design, manufacture, distribution, or use of any Licensed Products, Licensed Processes or materials by the Licensee, or other products or processes developed in connection with or arising out of the Licensed Patent Rights.

The Licensee agrees to maintain a liability insurance program consistent with so und business practice.

TERM, TERMINATION, AND MODIFICATION OF RIGHTS

This Agreement is effective when signed by all parties, unless the provisions of Paragraph 14.15 are not fulfilled, and shall extend on a Licensed Product-by-Licensed Product and country-by-country basis to the expiration of the last to expire of the Licensed Patent Rights covering the Licensed Product in such country unless sooner terminated as provided in this Article 13.

In the event that the Licensee is in default in the performance of any material obligations under this Agreement, including but not limited to the obligations listed in Paragraph 13.5, and if the default has not been remedied within [**] after the date of notice in writing of the default, the IC may terminate this Agreement by written notice and pursue outstanding royalties owed through procedures provided by the Federal Debt Collection Act.

In the event that the Licensee becomes insolvent, files a petition in bankruptcy, has such a petition filed against it, determines to file a petition in bankruptcy, or receives notice of a third party’s intention to file an involuntary petition in bankruptcy, the Licensee shall immediately notify the IC in writing.

The Licensee shall have a unilateral right to terminate this Agreement in any country or territory by giving the IC sixty (60) days written notice to that effect.

Subject to the cure provisions paragraphs 13.2 and 13.6, the IC shall specifically have the right to terminate or modify, at its option, this Agreement, if the IC reasonably determines that the Licensee:

is not executing the Commercial Development Plan submitted with its request for a license and the Licensee cannot otherwise demonstrate to the IC’s satisfaction that the Licensee has taken, or can be expected to take within a reasonable time, effective steps to achieve Practical Application of the Licensed Products or Licensed Processes;

has not achieved the Benchmarks as may be modified under Paragraph 9.2;

has willfully made a false statement of, or willfully omitted, a material fact in the license application or in any report required by this Agreement;

has committed a material breach of a covenant or agreement contained in this Agreement;

is not keeping Licensed Products or Licensed Processes reasonably available to the public after commercial use commences;

cannot reasonably satisfy unmet health and safety needs; or

cannot reasonably justify a failure to comply with the domestic production requirement of Paragraph 5.2, unless waived.

In making the determination referenced in Paragraph 13.5, the IC shall take into account the normal course of such commercial development programs conducted with sound and reasonable business practices and judgment and the annual reports submitted by the Licensee under Paragraph 9.2. Prior to invoking termination or modification of this Agreement under Paragraph 13.5, the IC shall give written notice to the Licensee providing the Licensee specific notice of, and a [**] opportunity to respond to the IC’s concerns as to the items reference d in 13.5(a)-13.5(g). If the Licensee fails to alleviate the IC’s concerns as to the items referenced in 13.5(a)-13.5(g) or fails to initiate connective action to the IC’s satisfaction, the IC may terminate this Agreement. Notwithstanding the above, with respect to items 13.5(e) and 13.5(f), the IC may only terminate the license with respect to the specific Licensed Product which gave rise to the IC’s concern regarding such items; this Agreement will otherwise remain in full force and effect.

The IC reserves the right according to 35 U.S.C. §209(d)(3) to terminate or modify this Agreement if it is reasonably determined that the action is necessary to meet the requirements for public use specified by federal regulations issued after the date of the license and these requirements are not reasonably satisfied by the Licensee.

Within [**] of receipt of written notice of the IC’s unilateral decision to modify or terminate this Agreement, the Licensee may, consistent with the provisions of 37 CFR §404.11, appeal the decision by written submission to the designated the IC official. The decision of the designated IC official shall be the final agency decision. The Licensee may thereafter exercise any and all administrative or judicial remedies that may be available.

Within [**] of expiration or termination of this Agreement under this Article 13, a final report shall be submitted by the Licensee. Any royalty payments, including those incurred but not yet paid (such as the full minimum annual royalty), and those related to patent expense, due to the IC shall become immediately due and payable upon termination or expiration. If terminated under this Article 13, sublicensees may elect to convert their sublicenses to direct licenses with the IC pursuant to Paragraph 4.3. Unless otherwise specifically provided for under this Agreement, upon termination or expiration of this Agreement , the Licensee shall return all Licensed Products or other materials included within the Licensed Patent Rights to the IC or provide the IC with written certification of the destruction thereof to the extent the same are covered by Licensed Patent Rights at such time. The Licensee may not be granted additional IC licenses if the final reporting requirement is not fulfilled.

GENERAL PROVISIONS

Neither party may waive or release any of its rights or interests in this Agreement except in writing. The failure of the Government to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right by the Government or excuse a similar subsequent failure to perform any of these terms or conditions by the Licensee.

This Agreement constitutes the entire agreement between the Parties relating to the subject matter of the Licensed Patent Rights, Licensed Products and Licensed Processes, and all prior negotiations, representations, agreements, and understandings are merged into, extinguished by, and completely expressed by this Agreement.

The provisions of this Agreement are severable, and in the event that any provision of this Agreement shall be determined to be invalid or unenforceable under any controlling body of law, this determination shall not in any way affect the validity or enforceability of the remaining provisions of this Agreement.

If either party desires a modification to this Agreement, the parties shall, upon reasonable notice of the proposed modification by the party desiring the change, confer in good faith to determine the desirability of the modification. No modification shall be effective until a written amendment is signed by the signatories to this Agreement or their designees.

The construction, validity, performance, and effect of this Agreement shall be governed by Federal law as applied by the Federal courts in the District of Columbia.

All Agreement notices required or permitted by this Agreement shall be given by prepaid, first class, registered or certified mail or by an express/overnight delivery service provided by a commercial carrier, properly addressed to the other party at the address designated on the Signature Page, or to any other address as may be designated in writing by such other party. Agreement notices shall be considered timely if such notices are received on or before the established deadline date or sent on or before the deadline date as verifiable by U.S. Postal Service postmark or dated receipt from a commercial carrier. Parties should request a legibly dated U.S. Postal Service postmark or obtain a dated receipt from a commercial carrier or the U.S. Postal Service. Private metered postmarks shall not be acceptable as proof of timely mailing.

This Agreement shall not be assigned or otherwise transferred (including any transfer by legal process or by operation of law, and any transfer in bankruptcy or insolvency, or in any other compulsory procedure or order of court), except to the Licensee’s Affiliate(s) or in connection with a sale or transfer of all or

The Licensee agrees in its use of any IC-supplied materials to comply with all applicable statutes, regulations, and guidelines, including the NIH and the HHS regulations and guidelines. The Licensee agrees not to use the materials for research involving human subjects or clinical trials in the United States without complying with 21 CFR Part 50 and 45 CFR Part 46. The Licensee agrees not to use the materials for research involving human subjects or clinical trials outside of the United States without notifying the IC, in writing, of the research or trials and complying with the applicable regulations of the appropriate national control authorities. Written notification to the IC of research involving human subjects or clinical trials outside of the United States shall be given no later than [**] prior to commencement of the research or trials.

The Licensee acknowledges that it is subject to and agrees to abide by the United States laws and regulations (including the Export Administration Act of 1979 and Arms Export Control Act) controlling the export of technical data, computer software, laboratory prototypes, biological materials, and other commodities. The transfer of these items may require a license from the appropriate agency of the Government or written assurances by the Licensee that it shall not export these items to certain foreign countries without prior approval of the agency. The IC neither represents that a license is or is not required or that, if required, it shall be issued.

The Licensee agrees to mark the Licensed Products or their packaging sold in the United States with all applicable U.S. patent numbers and similarly to indicate “Patent Pending” status. All Licensed Products manufactured in, shipped to, or sold in other countries shall be marked in a manner to preserve the IC patent rights in those countries.

By entering into this Agreement, the IC does not directly or indirectly endorse any product or service provided, or to be provided, by the Licensee whether directly or indirectly related to this Agreement. The Licensee shall not state or imply that this Agreement is an endorsement by the Government, the IC, any

The Parties agree to attempt to settle amicably any controversy or claim arising under this Agreement or a breach of this Agreement, except for appeals of modifications or termination decisions provided for in Article 13. The Licensee agrees first to appeal any unsettled claims or controversies to the designated the IC official, or designee, whose decision shall be considered the final agency decision. Thereafter, the Licensee may exercise any administrative or judicial remedies that may be available.

Nothing relating to the grant of a license, nor the grant itself, shall be construed to confer upon any person any immunity from or defenses under the antitrust laws or from a charge of patent misuse, and the acquisition and use of rights pursuant to 37 CFR Part 404 shall not be immunized from the operation of state or Federal law by reason of the source of the grant.

Paragraphs 8.1, 9.7-9.9, 12.1-12.5, 13.8, 13.9, 14.12 and 14.14 of this Agreement shall survive termination of this Agreement.

The terms and conditions of this Agreement shall, at the IC’s sole option, be considered by the IC to be withdrawn from the Licensee’s consideration and the terms and conditions of this Agreement, and the Agreement itself to be null and void, unless this Agreement is executed by the Licensee and a fully executed original is received by the IC within [**] from the date of the IC signature found at the Signature Page.

to reasonably seek the grant of a conditional (EU) or accelerated (US) approval for eligible patients, in keeping with applicable legal and regulatory regimes; and

to reasonably accommodate requests for pre-approval compassionate access to Licensed Products provided that such access is: (a) feasible, (b) in keeping with applicable legal and regulatory regimes, and (c) Licensee retains control over the Licensed Products and their dissemination.
