Manufacturing Agreement that accrued or arose prior to the Assignment Effective Time, unless expressly agreed upon by PRF and Eiger in the written assignment agreement effectuating such assignment; and (2) such Assigned Manufacturing Agreement shall, if agreed upon by the third party counter-party to such Assigned Manufacturing Agreement, be novated and assigned to PRF in its entirety (as may be modified by PRF and such counter-party)); (B) fulfill any outstanding orders for Licensed Progeria Product submitted by PRF pursuant to Section 22(c); and (C) except to the extent Eiger is obligated under the Merck License Agreement to deliver Eiger’s remaining inventory of Licensed Progeria Product to Merck, deliver to PRF all of the safety stock maintained by Eiger pursuant to Section 9(h). With respect to any other remaining inventory of Licensed Progeria Product of Eiger, the Parties shall discuss in good faith Eiger (as may be permitted by Merck if Merck does not exercise its rights under the Merck License Agreement to the Licensed Progeria Product possessed by Eiger) making available any such remaining inventory of Licensed Progeria Product to PRF. For the avoidance of doubt, any such remaining inventory of Licensed Progeria Product assigned to PRF other than the safety stock maintained by Eiger pursuant to Section 9(h) shall be delivered on an “as is” basis without warranty of any kind, and PRF shall be responsible for requalification or other requirements for research use or use in humans under any applicable laws, rules and regulations with respect to such remaining inventory. In the event Eiger provides to PRF any such remaining inventory of Licensed Progeria Product other than such safety stock, Eiger shall provide to PRF [ * ].

10.Delivery. Eiger shall deliver the Licensed Progeria Product [ * ] to PRF or its designee (provided that all products in a single order will be delivered to a single place of destination in the U.S.) by PRF’s requested delivery date, provided that with respect to Licensed Progeria Product, PRF supply orders are made in accordance with Section 9(a). Delivery of the Licensed Progeria Product intended to be used for Research Activities outside of the U.S. shall be [ * ] for PRF to undertake export, shipment and delivery outside of the U.S. For clarity, this Section 10 does not apply to, and Eiger remains solely responsible for, the delivery of all Licensed Progeria Product under the global patient support program described in Section 7 and the expanded access or other “named patient” programs described in Section 8.

11.Supply of Licensed API.

(a)Eiger shall supply and deliver to PRF an average quantity of [ * ] of Licensed API (or such higher quantity as reasonably agreed upon by the Parties) per calendar year (the “Applicable Calendar Year”), at no cost or expense to PRF, for inclusion in and distribution by PRF’s Cell and Tissue Bank (information about which is located, as of the Effective Date, at https://www.progeriaresearch.org/cell-and-tissue-bank/). Eiger may supply and deliver such average quantity of Licensed API during such Applicable Calendar Year or the immediately subsequent calendar year (the “Subsequent Calendar Year”), but the supply and delivery of such average quantity of Licensed API for the Applicable Calendar Year during the Subsequent Calendar Year shall not decrease Eiger’s obligation to supply and deliver such average quantity of Licensed API for the Subsequent Calendar Year. Eiger shall deliver such Licensed API to [ * ], unless the Parties otherwise agree in writing to an alternative delivery location, [ * ], by delivery dates reasonably agreed upon by the Parties in writing.

~~179161731 v1~~

EXECUTION VERSION

(b)Eiger shall (i) retain a sample of each batch of the Licensed API supplied under or pursuant to this Agreement and (ii) maintain and provide to PRF reasonable access to records of the Licensed API in each shipment, including CoAs. As reasonably requested by PRF, Eiger shall promptly provide PRF (A) a copy of such CoAs and (B) access to a copy of any such other records described in subclause (ii) of the foregoing sentence and any records of testing performed on such Licensed API (as such testing records are required to be maintained by Eiger pursuant to any applicable law, statute, rule or regulation).

12.Rejection.

(a)For each shipment of the Licensed Progeria Product, Eiger shall provide PRF with a CoA no less than [ * ] days before shipping. PRF shall reasonably promptly review the CoA and notify Eiger in writing within [ * ] days after PRF’s receipt of such CoA of any non-conformance PRF identifies in the CoA. If no notification is provided from PRF, then Eiger shall ship the Licensed Progeria Product as scheduled, and PRF (or its designee) shall inspect the Licensed Progeria Product upon its receipt thereof. Within ten [ * ] days after delivery of any Licensed Progeria Product, PRF may reject all or any portion of any shipment of the Licensed Progeria Product that (i) has been damaged or tampered with (or the container or packaging of which has been damaged or tampered with) prior to receipt of such Licensed Progeria Product by or on behalf of PRF or its designee, (ii) is not in conformance with the approved Eiger IND or NDA for such Licensed Progeria Product or (iii) is adulterated or misbranded within the meaning of such terms under the Federal Food, Drug and Cosmetic Act (each of such Licensed Progeria Product, a “Non-Conforming Product”).

(b)In order to reject a shipment of the Licensed Progeria Product, PRF must provide Eiger with a written notice of rejection and the basis therefor within [ * ] days after PRF’s receipt of such shipment, except that in the case of any Licensed Progeria Product having any latent defect which, upon reasonable examination by PRF or its designee, could not have been discovered within such [ * ] day period after receipt thereof, PRF must provide Eiger with a notice of rejection and the basis therefor within [ * ] days after PRF becomes aware of such defect. Any notice of rejection from PRF must contain reasonable documentation to allow Eiger to reasonably determine whether such rejected Licensed Progeria Product is a Non-Conforming Product. If no such notice of rejection is received by Eiger within the applicable [ * ] day period set forth above, PRF shall be deemed to have accepted such delivery of such Licensed Progeria Product, as the case may be.

(c)If in good faith Eiger does not accept PRF’s basis for rejection of any Licensed Progeria Product, the Parties shall engage a mutually acceptable independent third party laboratory to test the putative Non-Conforming Product in question to determine if such Licensed Progeria Product is a Non-Conforming Product. The determination of such laboratory shall be binding upon the Parties, and the costs of such testing shall be shared equally by the Parties.

~~179161731 v1~~

EXECUTION VERSION

(d)If Eiger accepts PRF’s basis for rejection of any Licensed Progeria Product or if any such independent third party laboratory determines that the Licensed Progeria Product in question is a Non-Conforming Product, promptly upon receipt of such notice of rejection or such determination, Eiger shall, at PRF’s request, use commercially reasonable efforts to promptly provide PRF with replacement Licensed Progeria Product in the same quantity as the Non-Conforming Product. Unless Eiger requests the return of a rejected batch of the Licensed Progeria Product within [ * ] after the later of the receipt of PRF’s notice of rejection or, if applicable, the independent third party laboratory’s determination that such Licensed Progeria Product is a Non-Conforming Product, PRF shall destroy such rejected batch of the Licensed Progeria Product and provide Eiger with written certification of such destruction. Within [ * ] after PRF’s receipt of a written request from Eiger for the return of a rejected batch of the Licensed Progeria Product, PRF shall return such rejected batch to Eiger, at Eiger’s cost and expense.

13.Recalls; Safety Reporting. Eiger shall have sole decision-making authority with respect to, and shall bear all costs and expenses relating to, issuing any recall, market withdrawal or correction of any Licensed Progeria Product provided by Eiger or with respect to issuing any advisory letter or other safety related communication with respect to any Licensed Progeria Product provided by Eiger. Eiger shall notify PRF in writing promptly (and in any event within (a) [ * ] after Eiger’s receipt of any written notice or other communication from a regulatory agency that could reasonably be expected to result in any recall, market withdrawal, correction or suspension of distribution of any Licensed Progeria Product or (b) [ * ] after Eiger’s receipt of any written notice or other communication from a regulatory agency that could reasonably be expected to result in any clinical hold of any Licensed Progeria Product) if any Licensed Progeria Product, or any Licensed API contained therein, is alleged or proven to be the subject of any recall, market withdrawal, correction, clinical hold or suspension of distribution. PRF will make available to Eiger, upon Eiger’s written request, all of PRF's pertinent records in its Control relating to such Licensed Progeria Product that Eiger may reasonably request to assist in effecting any such recall, market withdrawal or correction. If either Party becomes aware of any information that reasonably suggests that a death or serious adverse reaction or injury will impact the Commercialization or development of the Licensed Progeria Product, such Party will (i) furnish such information to the other Party within [ * ] after such Party becomes aware of such information and (ii) make, maintain and retain records of such information.

14.Inventory Records. PRF shall keep Eiger reasonably informed of its use of all Licensed Progeria Product and shall keep full and accurate records of its receipt, use and inventory of any Licensed Progeria Product. Within [ * ] after the end of each [ * ], PRF shall provide Eiger with a written inventory report for the Licensed Progeria Product, documenting amounts of the Licensed Progeria Product being allocated to Research Activities and amounts otherwise being held in the possession of PRF, if any.

The Parties acknowledge that discussions between the Parties in an attempt to resolve any disputes are settlement discussions under applicable rules of evidence and without prejudice to either Party's legal position.

(b) Arbitration. Any dispute that is not resolved pursuant to Section 27(a), except for any dispute, claim or controversy subject to Section 27(b)(vi), shall be settled by binding arbitration administered by federal arbitration before a single arbitrator having substantial experience with commercial transactions in the pharmaceutical industry. Such arbitration shall be governed by the U.S. Federal Arbitration Act, 9 U.S.C. §§ 1-16 (the “Federal Arbitration Act”), to the exclusion of any inconsistent state laws and conducted in accordance with the Arbitration Rules and Procedures of the Judicial Arbitration and Mediation Service, Inc. (“JAMS”) then in effect. The arbitration will be conducted promptly in Boston, Massachusetts, and the Parties consent to the personal jurisdiction of the Federal District Court in the District of Massachusetts for any case arising out of or otherwise related to the arbitration, its conduct or its enforcement. Each Party shall have [ * ] to present its case, and the Parties shall jointly request that the arbitrator render a final decision within [ * ] following completion of each Party’s presentation or as soon thereafter as is practicable.

(i)Any award shall be promptly paid free of any tax, deduction or offset, and any costs, fees or taxes incident to enforcing the award shall, to the maximum extent permitted by law, be charged against the Party resisting enforcement. The prevailing Party in the arbitration shall be entitled to receive reimbursement of its reasonable expenses (including reasonable attorneys’ fees, expert witness fees and all other expenses) incurred in connection with such arbitration. Each Party agrees (A) to abide by the award rendered in any arbitration conducted pursuant to this Section 27(b) and (B) that, subject to the Federal Arbitration Act, judgment may be entered upon the final award in the Federal District Court in the District of Massachusetts and that other courts may award full faith and credit to such judgment in order to enforce such award. The award shall include interest from the date of any damages incurred for breach of this Agreement, and from the date of the award until paid in full, at a rate fixed by the arbitrator.

(ii)Except as set forth in Section 27(b)(i), each Party shall bear its own legal fees. The arbitrators shall have the authority to grant specific performance or to allocate between the Parties the costs of arbitration (including service fees, arbitrator fees and all other fees related to the arbitration) in such equitable manner as the arbitrator may determine.

(iii)Provided a Party has made a sufficient showing under the rules and standards set forth in the U.S. Federal Rules of Civil Procedure and applicable case law, the arbitrator shall have the freedom to invoke, and the Parties agree to abide by, injunctive

measures after either Party submits in writing for arbitration claims requiring immediate relief. Additionally, nothing in this Section 27 will preclude either Party from seeking any injunctive relief from a court of competent jurisdiction, including a temporary restraining order, preliminary injunction, permanent injunction or other equitable relief, concerning a dispute either prior to, during or after any arbitration if necessary to protect the interests of such Party or to preserve the status quo pending the arbitration proceeding.

(iv)The arbitration proceeding will be confidential and the arbitrator shall issue appropriate protective orders to safeguard each Party's Confidential Information.

(v)Any duty to arbitrate under this Agreement shall remain in effect and be enforceable after expiration or termination of this Agreement for any reason.

28.Notices. All notices required or permitted to be given under this Agreement will be in writing and will be sent by an overnight courier service with package tracking capabilities and costs prepaid, by registered or certified airmail, return receipt requested and postage prepaid, to the other Party at the addresses set forth in the preamble of this Agreement and to the attention of President and Executive Director (in the case of PRF) or the President and CEO (in the case of Eiger). Such notices will be deemed to have been given when received by the addressee. Any Party may give written notice of a change of address in accordance with this Section 28, whereupon any notice or request will thereafter be given to such Party as above provided at such changed address.

29.Severability. If any provision of this Agreement is held to be illegal or unenforceable, such provision will be limited or eliminated to the minimum extent necessary so that the remainder of this Agreement will continue in full force and effect and be enforceable, and the validity, legality and enforceability of the remaining provisions will not in any way be affected or impaired thereby. The Parties agree to negotiate in good faith an enforceable substitute provision for any invalid or unenforceable provision that most nearly achieves the Parties’ intent of such provision.

30.Construction; Headings. No rule of construction that disfavors the drafting party will apply to this Agreement. As used in this Agreement, “including” and words of similar import mean “including but not limited to.” The use of “or” will not be deemed to be exclusive.
