ASSET PURCHASE AGREEMENT

THIS ASSET PURCHASE AGREEMENT (this “Agreement”) is entered into as of December 22, 2016, by and between RaNA Therapeutics, Inc., a Delaware corporation (the “Buyer”), and Shire Human Genetic Therapies, Inc., a Delaware corporation (the “Seller”).

Introduction

The Seller desires to sell, transfer and assign to the Buyer, and the Buyer desires to purchase from the Seller, the Transferred Assets (as defined below), subject to the assumption by the Buyer of the Assumed Liabilities (as defined below), upon the terms and subject to the conditions set forth in this Agreement.

In contemplation of and in order to facilitate the consummation of the First Tranche (as defined below) and the execution and closing of this Agreement, on December 5, 2016, the former members of RaNA Therapeutics, LLC (“RaNA LLC”) exchanged their interests in RaNA LLC for shares of capital stock of the Buyer pursuant to a merger of a wholly owned subsidiary of the Buyer with and into RaNA LLC (the “Incorporation”).

The Buyer and the Seller intend to treat (i) the Incorporation, (ii) the transfer by the Seller of the Transferred Assets (as defined below) to the Buyer in exchange for the Aggregate Consideration (as defined below) and the assumption of the Assumed Liabilities (as defined below), and (iii) the First Tranche (as defined below) as an integrated transaction governed by Section 351 of the Internal Revenue Code of 1986, as amended (the “Code”).

In consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth below, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Buyer and the Seller agree as follows:

ARTICLE I

Upon the terms and subject to the conditions set forth in this Agreement, at the Closing, the Seller agrees to sell, convey, transfer, assign and deliver to the Buyer, and the Buyer agrees to purchase from the Seller and the Selling Subsidiaries, the Transferred Assets, in each case, free and clear of all Liens other than Permitted Liens. For purposes of this Agreement, “Transferred Assets” means all of the Seller’s and the Selling Subsidiaries’ right, title and interest in and to the following assets as such right, title and interest exist as of immediately prior to the Closing:

(b) all regulatory filings, marketing authorizations, permits, licenses, registrations, regulatory clearances, approvals, concessions, qualifications, registrations, certifications and similar items in each case granted by or issued pursuant to the authority of any Governmental Entity (“Permits”) that are exclusively or primarily used or held for use in connection with, or are exclusively or primarily related to, the MRT Program as of immediately prior to the Closing, in each case, in or related to any jurisdiction anywhere in the world (the “Transferred Permits”), including those set forth on Schedule 1.1(b); provided that the Seller shall have the right to retain copies of any such Transferred Permits for its compliance records;

(c) any and all Know-How owned by the Seller or any of the Selling Subsidiaries that is exclusively or primarily used or held for use by the Seller or any of the Selling Subsidiaries in connection with, or is exclusively or primarily related to, the MRT Program as of immediately prior to the Closing (the “Transferred Know-How”), including the Know-How set forth on Schedule 1.1(c);

(d) the real property lease set forth on Schedule 1.1(d) (the “Lease”) (together with all rights, title and interest of the Seller and the Selling Subsidiaries in and to leasehold improvements relating thereto, excluding security deposits, reserves or prepaid rents in connection therewith) (such real property, the “Leased Real Property”);

(e) all of the inventory (i) exclusively related to the MRT Program as of immediately prior to the Closing, including the existing finished quantities, work in process, raw materials, constituent substances, materials, stores and supplies, as well as any trade and sample inventories, (ii) located on the Leased Real Property at ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇▇ and (iii) set forth on Schedule 1.1(e) (clauses (i), (ii) and (iii), collectively, the “Transferred Inventory”);

(f) all contracts, leases (other than real property leases), deeds, mortgages, licenses, instruments, notes, commitments, undertakings, indentures, and all other agreements, commitments and legally binding arrangements, whether written or oral (“Contracts”), that are exclusively or primarily used or held for use in connection with, or are exclusively or primarily related to, the MRT Program (the “Transferred Contracts”), including those set forth on Schedule 1.1(f) (as amended);

(g) all books, documentation, ledgers, files, reports, plans and operating records of the Seller or the Selling Subsidiaries that are exclusively or primarily related to the MRT Program (and not any Excluded Asset or Retained Liability) (the “Transferred Books and Records”); provided that (i) the Seller shall have the right to retain copies of any such Transferred Books and Records for its compliance records and (ii) the Seller shall have the right to retain originals of any laboratory notebooks included in the Transferred Books and Records and provide the Buyer with copies of such notebooks;

(h) all rights to any actions, suits, claims or causes of action arising out of or relating to any of the Transferred Contracts on or after the Closing;

(i) all furniture and equipment that are exclusively or primarily used or held for use in connection with, or are exclusively or primarily related to, the MRT Program, including those set forth on Schedule 1.1(i);

(j) the information technology equipment set forth on Schedule 1.1(j) (the “Transferred Internal Systems”); and

(k) all other assets, rights and properties (excluding any asset, right or property of a type described in the categories of assets, rights and properties addressed in clauses (a) through (j) above, including, for the avoidance of doubt, any Intellectual Property) of the Seller or any of the Selling Subsidiaries that are exclusively or primarily used or held for use in connection with, or are exclusively or primarily related to, the MRT Program as of immediately prior to the Closing, except for any such assets, rights or properties that are material to Seller Parent, any of its Affiliates or any of its or their programs or business units.

Notwithstanding the foregoing, the Buyer acknowledges and agrees that (i) the Seller and its Affiliates may retain possession of and use any Transferred Asset necessary or desirable for the Seller and its Affiliates to perform its obligations under the Transition Services Agreement, in which case the Seller and its Affiliates shall be under no obligation to deliver such Transferred Assets, and may use such assets, in connection with such performance until the termination of the Transition Services Agreement, and (ii) in respect of the items described in Section 1.1(a), Section 1.1(b), and Section 1.1(g) (including, for the avoidance of doubt, e-mails and electronic data): (x) with respect to any portions of such items that do not relate solely to the Transferred Assets or the Assumed Liabilities or are also required for the operation of the Excluded Assets or relate to the Retained Liabilities, the Seller and its Affiliates may retain the originals of such items, and deliver, or cause to be delivered, copies thereof to the Buyer and redact from any such items any information that is not related to the Transferred Assets or the Assumed Liabilities, (y) to the extent the delivery of any such items is not reasonably practicable at the Closing, the Seller and its Affiliates will have up to 60 calendar days following the Closing (or such longer time as provided in the Transition Services Agreement) to deliver such items to the Buyer (and, in the case of inactive laboratory notebooks or laboratory notebooks that do not relate exclusively to the MRT Program, will use commercially reasonable efforts to deliver such items in due course) and (z) the Seller shall only have an obligation to physically deliver such items to the extent in the possession or control of the Seller or the Selling Subsidiaries.

After the Closing, if the Seller determines in good faith that any of the Contracts listed on Schedule 1.2(b) under the heading “Potentially Shared Contracts” are exclusively used or held for use in, or exclusively related to, the MRT Program and notifies the Buyer of such determination, such Contract shall be a Transferred Contract for all purposes hereunder (subject to the terms and conditions hereof, including Section 1.10), and the Buyer agrees to assume all Assumed Liabilities with respect thereto.

Notwithstanding anything to the contrary in this Agreement, the Buyer is only purchasing the Transferred Assets, and the Transferred Assets shall not include any of the Excluded Assets. For purposes of this Agreement, “Excluded Assets” means all assets, rights and properties of the Seller or any of its Affiliates other than the Transferred Assets.

(a) all Liabilities related to or arising out of any Transferred Asset or the MRT Program that arise at or after the Closing;

(b) the Liabilities under the Transferred Contracts or the Lease (excluding, for the avoidance of doubt, any Liabilities that may arise out of or relate to any breach of any of the Transferred Contracts that exist or occur prior to the Closing);

(c) all Liabilities related to (i) any Transferred Employee, or Persons asserting claims on behalf of such Transferred Employee, including any liability for compensation or employment, labor, pension or personnel benefits and the employer portion of any Taxes with respect thereto, solely to the extent that such Liabilities arise at or after the Closing, and (ii) the Buyer’s obligations under Section 4.7, including any severance obligations with respect to any Business Employee;

1.7. Taxes and Fees.

(a) Transfer Taxes. All transfer, sales, and use taxes, deed excise stamps and similar charges (“Transfer Taxes”) related to the Contemplated Transactions shall be borne equally, one-half by the Seller and one-half by the Buyer. The required party shall file all necessary Tax Returns and other documentation with respect to such Transfer Taxes required by a Governmental Entity to be filed and, if required by applicable Law, the other party will, and will cause its controlled Affiliates to, join in the execution of any such Tax Returns and other documentation. The Seller and the Buyer shall cooperate in the preparation and filing of all forms and documentation necessary to provide exemption from Transfer Tax, to the extent permitted by applicable Law.

(b) Withholding Taxes. The Buyer will be entitled to deduct and withhold from the amounts otherwise payable by it pursuant to this Agreement such amounts as it reasonably determines that it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign Tax Law, and to collect any necessary Tax forms, including Forms W-8 or W-9, as applicable, or any similar information, from the Seller and any other recipient of payments hereunder; provided, however, that the Buyer will (i) promptly (and in any event no later than five (5) Business Days prior to the date on which such payment is made) notify the Seller of any intention to so deduct and withhold with respect to any payment to the Seller and provide the Seller a reasonable opportunity to provide any statement, form, or other documentation that would

reduce or eliminate any such requirement to deduct and withhold (provided, however that no delay or failure on the part of the Buyer in so notifying the Seller shall relieve the Seller of any liability with respect to such deduction or withholding except to the extent the Seller is actually prejudiced thereby); (ii) remit and report any such amount required to be deducted and withheld to the applicable Governmental Entity in accordance with applicable Law; (iii) upon request, promptly provide to the Seller a certificate, receipt or other documentation of proof of such remittance reasonably acceptable to the Seller; and (iv) cooperate with the Seller (at the Seller’s expense) as reasonably requested with respect to the filing of any Tax Return or conduct of any claim relating to any available refund of such amount remitted. In the event that any amount is so deducted and withheld, and properly remitted, such amount will be treated for all purposes of this Agreement as having been paid to the person to whom the payment from which such amount was withheld was made.

1.8. Intended Tax Treatment. The Buyer and the Seller acknowledge and agree (i) that (x) the Incorporation, (y) the transfer of the Transferred Assets by the Seller to the Buyer in exchange for the Aggregate Consideration and the assumption of the Assumed Liabilities, and (z) the First Tranche (as defined below) are intended to qualify as an integrated transaction governed by Section 351 of the Code and (ii) each of them shall exchange the information required and file all Tax Returns in a manner consistent with this treatment unless an alternative position is required pursuant to a final determination as defined in Section 1313 of the Code.

1.9. Wrong Pocket Assets.

(a) If at any time, or from time to time after the Closing, Seller Parent or any of its controlled Affiliates, including the Seller, on the one hand, or the Buyer or any of its controlled Affiliates, on the other hand, shall receive or otherwise possess any asset or right (including cash) that should belong to the Buyer, on the one hand, or the Seller or any of its Affiliates, on the other, pursuant to this Agreement, the Seller or the Buyer (as the case may be) shall promptly transfer, or cause to be transferred, such asset or right to the Person so entitled thereto. Prior to any such transfer in accordance with this Section 1.9, the Person receiving or possessing such asset shall hold such asset in trust for such other Person. Without limitation of the foregoing, in the event Seller Parent or any of its controlled Affiliates receives any payment in respect of any Transferred Asset or Buyer or any of its controlled Affiliates receives any payment in respect of an Excluded Asset, the Seller or the Buyer (as applicable) shall promptly deliver such payment to an account designated in writing by the Buyer or the Seller (as applicable) by wire transfer of immediately available funds.

(b) Notwithstanding anything in this Agreement to the contrary, with respect to any purchase orders that are outstanding as of immediately prior to the Closing that are exclusively or primarily used or held for use in connection with, or are exclusively or primarily related to, the MRT Program, even if such purchase orders are issued under a Contract that is not included in the Transferred Assets (collectively, the “Specified Purchase Orders”), the parties agree that the Buyer shall be responsible for all Liabilities under the Specified Purchase Orders (excluding, for the avoidance of doubt, any Liabilities that may arise out of or relate to any breach of any of the Specified Purchase Orders that exist or occur prior to the Closing). The parties will work in good faith to identify the Specified Purchase Orders promptly after the Closing.

1.10. Consents.

Anything in this Agreement to the contrary notwithstanding, this Agreement shall not constitute an agreement to assign or transfer any Transferred Asset or any claim, right or benefit arising thereunder or resulting therefrom, if an attempted assignment or transfer thereof, without the consent of a third party or a Governmental Entity would constitute a breach thereof or in any way adversely affect the rights or obligations of the Buyer, the Seller or any Selling Subsidiary thereunder or violate any applicable Law (any such Transferred Asset, claim, right or benefit, a “Deferred Item”). If any such required consent is not obtained (such consent, a “Deferred Consent”), then, in each such case, (a) the Deferred Item shall be withheld from sale pursuant to this Agreement without any reduction in the Closing Date Consideration or any Contingent Payments, (b) from and after the Closing, the Seller and the Buyer will use commercially reasonable efforts to cooperate to seek to obtain such Deferred Consent as soon as practicable after the Closing and (c) until such Deferred Consent is obtained, the Seller and the Buyer will use commercially reasonable efforts to cooperate to provide to the Buyer the benefits under the Deferred Item to which such Deferred Consent relates in a manner that would not require any Deferred Consent (with the Buyer entitled to all the benefits and subject to all the Liabilities thereunder (as Assumed Liabilities) arising on or after the Closing (i) except for any obligations to the extent arising from or related to any breach or violation thereunder prior to the Closing or any act or omission prior to the Closing that would have constituted a breach or violation thereunder upon notice or passage of time and (ii) without limiting the Seller’s liability under Article V for any breach of any representation, warranty, covenant or agreement of the Seller in this Agreement). In particular, in the event that any such Deferred Consent is not obtained prior to the Closing, then the Buyer and the Seller shall use commercially reasonable efforts to enter into such arrangements (including subleasing or subcontracting if permitted) in a manner that would not require any Deferred Consent to provide to the parties the economic and operational equivalent of obtaining such Deferred Consent and assigning or transferring such Transferred Asset, including (at the Buyer’s cost and expense) enforcement by the Seller for the benefit of the Buyer of all claims or rights arising thereunder relating to the post-Closing period, and the performance by the Buyer of the obligations thereunder on a prompt and punctual basis. Nothing in this Agreement (including in this Section 1.10) shall require either party or any of their respective Affiliates to pay any money or other consideration or grant any other accommodation to any Person (including any amendment to any Transferred Contract or other modification of any Transferred Asset) or to initiate any claim or proceeding against any Person. For the avoidance of doubt, neither the Seller nor any of its Affiliates shall have any obligation to obtain any Deferred Consent or to provide such an alternative arrangement (and the failure to do so shall not, in and of itself, be deemed to be a breach of the Seller’s representations, warranties or covenants hereunder) other than the undertaking to use commercially reasonable efforts to obtain or provide the same set forth in this Section 1.10. For the avoidance of doubt, neither the Seller nor any of its Affiliates warrants, or shall be responsible for, the successful maintenance or renewal of any Transferred Permit.

1.11. Contingent Payments.

(a) Milestone Events and Milestone Payments. Subject to the terms and conditions of this Agreement, Buyer shall make each applicable payment (each a “Milestone Payment”) set forth in Section 1.11(a)(i), Section 1.11(a)(ii) or Section 1.11(a)(iii) to the Seller promptly (and in any event no later than [**]) after the achievement by any member of the Buyer Rights Group of the relevant event listed under Sections 1.11(a)(i), Section 1.11(a)(ii) or Section 1.11(a)(iii), respectively (each, a “Milestone Event”).

(i) A one-time payment of [**] Dollars ($[**]) upon the First Commercial Sale of any CFTR MRT Product in the United States or European Union;

(ii) With respect to each Non-CFTR MRT Product, a one-time payment of Ten Million Dollars ($10,000,000) upon the First Commercial Sale of such Non-CFTR MRT Product [**], provided, however, that the Milestone Payment in this Section 1.11(a)(ii) shall be due no more than once with respect to any two Non-CFTR MRT Products if all of the MRT Compound(s) in one of the Non-CFTR MRT Products are the same as all of the MRT Compound(s) in the other Non-CFTR MRT Product (it being understood that, for purposes of this Section 1.11(a)(ii), (A) any metabolite, prodrug, hydrate or other solvate, analog, ester, salt, intermediate, stereoisomer, racemate, tautomer or polymorph of any MRT Compound shall be considered the same MRT Compound and (B) any MRT Compound containing a different sequence than (e.g., an optimized sequence of) any other MRT Compound shall be considered a different MRT Compound from such other MRT Compound), regardless of whether such Non-CFTR MRT Products containing such MRT Compound(s) have different strengths, formulations, dosage forms or modes of administration or are marketed and sold for different Indications; and

(iii) A one-time payment of [**] Dollars ($[**]) upon the first achievement of the aggregate Annual Net Sales of any MRT Product equaling or being greater than [**] Dollars ($[**]) (it being understood that the Annual Net Sales of any two MRT Products may be aggregated to determine whether the Milestone Event in this Section 1.11(a)(iii) has been achieved only if all of the MRT Compound(s) in one of the MRT Products are the same as all of the MRT Compound(s) in the other MRT Product (it being understood that, for purposes of this Section 1.11(a)(iii), (A) any metabolite, prodrug, hydrate or other solvate, analog, ester, salt, intermediate, stereoisomer, racemate, tautomer or polymorph of any MRT Compound shall be considered the same MRT Compound and (B) any MRT Compound containing a different sequence than (e.g., an optimized sequence of) any other MRT Compound shall be considered a different MRT Compound from such other MRT Compound), regardless of whether such MRT Products have different strengths, formulations, dosage forms or modes of administration or are marketed and sold for different Indications.

(b) For the avoidance of doubt, (i) no payment under Section 1.11(a)(i) or Section 1.11(a)(iii) shall be paid more than once, (ii) in no event shall the Buyer pay or otherwise owe any amounts in excess of Sixty Million Dollars ($60,000,000) in the aggregate pursuant to Section 1.11(a)(i) and Section 1.11(a)(iii) and (iii) without limiting the Buyer’s obligations hereunder (including under Section 1.11(e)), the Buyer does not represent or warrant that the development and commercialization of any MRT Product will be successful.

(i) Earn-Out Payment Rate. Subject to the remainder of this Section 1.11(c), with respect to each MRT Product in each country, Buyer shall pay to the Seller quarterly payments equal to [**] percent ([**]%) (“Earn-Out Payment Rate”) of Net Sales of each such MRT Product in each such country during the applicable Earn-Out Period (each such payment, on an MRT Product-by-MRT Product, quarter-by-quarter and country-by-country basis, an “Earn-Out Payment”).

(ii) Patent Right Expiration. With respect to any MRT Product in any country, if there is no Valid Claim that Covers such MRT Product (or any element thereof) in such country, then the Earn-Out Payment Rate for such MRT Product in such country shall be reduced by [**] percent ([**]%).

(d) Exception for Seller Activities. Notwithstanding anything to the contrary herein and for the avoidance of doubt, no Milestone Payment or Earn-Out Payment shall be due to the Seller for any MRT Product sold by Seller Parent or any of its controlled Affiliates, any of their respective distributors on their behalf or any of their respective licensees with respect to such MRT Product if such MRT Product was licensed to or acquired by Seller Parent or any of its controlled Affiliates from a member of the Buyer Rights Group.

(e) Diligence.

(i) During the Developmental Diligence Period, the Buyer shall, and shall cause the members of the Buyer Rights Group to, use Commercially Reasonable Efforts to develop MRT Products, seek and obtain Regulatory Approval therefor and achieve the Developmental Milestone Events.

(ii) From the date hereof until the end of the Earn-Out Period with respect to any MRT Product in any country, the Buyer shall, itself or through the members of the Buyer Rights Group, use Commercially Reasonable Efforts to market and sell such MRT Product in such country.

(iii) Other than the diligence obligations specifically set forth in this Section 1.11(e), neither the Buyer nor any other member of the Buyer Rights Group shall have other diligence obligations with respect to achievement of any Milestone Event, or to develop, market or sell any MRT Product.

(f) Methods of Payments; Foreign Currency. All Contingent Payments shall be paid in U.S. dollars by wire transfer to an account designated in writing by the Seller. For all Net Sales and Exclusions denominated in any currency other than U.S. dollars, the amount of such Net Sales and Exclusions shall be converted into U.S. dollars using the exchange rate for the relevant month (the “Monthly Rate”), such Monthly Rate being determined as the last price rate of exchange for such currencies on the last business day of the immediately preceding calendar month as published on Bloomberg page FXC (or such other publication as may be agreed upon in writing between the parties from time to time).

(g) Reporting.

(i) Within [**] following January 1st of each calendar year commencing in 2018 and continuing until [**] following the end of the Developmental Diligence Period, the Buyer shall provide the Seller with a reasonably detailed written report (each, an “Annual Report”) summarizing the status of the development of the MRT Products in order to achieve any Developmental Milestone Event that had not yet been achieved. Following receipt by the Seller of each Annual Report, the Seller may request a meeting with knowledgeable senior representatives of Buyer who are directly involved and engaged in the development activities of MRT Products, which meeting shall take place promptly, and in any event not later than [**] following such request, in person or by telephone conference or video conference as mutually agreed. At such meeting, such representatives of Buyer shall promptly respond, during such meeting (or, if not then practicable, as promptly as practicable thereafter), to the Seller’s reasonable inquiries to the extent appropriate for the purpose of providing the Seller with a reasonably detailed understanding of the efforts of Buyer to achieve the Milestone Events and Buyer’s progress with respect thereto.

(ii) The Buyer shall provide written notice to the Seller of the achievement of each Developmental Milestone Event no later than [**] after the occurrence thereof or after Buyer becomes aware of the achievement of such Developmental Milestone Event.

(iii) The Buyer shall, and shall cause the other members of the Buyer Rights Group to, keep books and records sufficient to determine the achievement of any Milestone Event and to calculate Contingent Payments.

(iv) With respect to each calendar quarter during the relevant Earn-Out Period, on an MRT Product-by-MRT-Product and country-by-country basis, the Buyer shall furnish the Seller with a report, within [**] after the end of such quarter, setting forth, with respect to each MRT Product in each country, Buyer’s good faith calculation of (A) the Net Sales during such calendar quarter and (B) the Exclusions with respect to the calculation of Net Sales for such calendar quarter.

(h) Audits. Upon the written request of the Seller, the Buyer shall, and shall cause the other members of the Buyer Rights Group to, permit an independent public accountant selected by the Seller and reasonably satisfactory to the Buyer and the relevant member of the Buyer Rights Group (the “Accountant”) to have reasonable access upon reasonable prior notice and during normal business hours, but no more than [**], to review the records specified in Section 1.11(g)(iii) solely for the purpose of determining the accuracy of the reports described in Section 1.11(g)(i) and (iv) (an “Audit”), at the Seller’s expense. Before conducting the Audit, the Accountant must execute a reasonable confidentiality agreement with the Buyer and, if applicable, the relevant Buyer Rights Group member. If the Accountant concludes that any Contingent Payment was not paid when due, the Seller shall be entitled to deliver a written notice of such non-payment (a “Dispute Notice”), in which case the Seller and the Buyer shall, for a period of not less than [**] after delivery of the Dispute Notice, attempt in good faith to resolve the items in dispute. If no agreement is reached by the Seller and the Buyer as to the calculation of the disputed amount within [**] after delivery of a Dispute Notice, then either party shall have the right to pursue applicable legal remedies in accordance with the provisions of Section 6.10. If the Seller and the Buyer agree, or any dispute resolution

mechanism determines that, any Earn-Out Payment or any Milestone Payment was not paid as a result of an underreporting of Net Sales by more than [**] percent ([**]%), the Buyer shall reimburse the Seller for the reasonable out-of-pocket costs of the Audit. A quarterly period can only be subject to an Audit [**] and the Seller shall not be permitted to Audit a calendar quarter more than [**].

(i) Overdue Payments. Any portion of any Contingent Payment not paid when due shall bear interest from the due date until the date of payment thereof at a per annum rate equal to [**] percentage points above the prime rate as reported by the Wall Street Journal, from time to time, compounded annually; provided that interest shall not accrue at a rate that exceeds the maximum rate permitted by applicable Law.

(j) Contractual Right Only. The rights and obligations of the Seller under this Section 1.11, including the right to receive payments, (i) are purely contractual rights and not a security for purposes of any federal or state securities Laws, (ii) will not be represented by any form of certificate or instrument, (iii) do not give the Seller any dividend rights, voting rights, liquidation rights, preemptive rights or other rights common to holders of the Buyer’s equity securities and (iv) are not transferrable, assignable or redeemable (other than indirect transfers or assignments, transfers by operation of law or transfers or assignments to any Affiliate of the Seller).

(k) ROFN. Until the first dosing of the first patient with a CFTR MRT Product in a Phase 3 Trial, the Buyer shall notify the Seller in writing (each such notice, a “ROFN Notice”) (i) promptly after (x) the Buyer or any of its Affiliates receives from a third party (other than (1) any Affiliate of the Buyer or (2) any academic or non-profit research institution, hospital, contract research organization, contract manufacturer, contract employee, consultant or other third party, in the case of both clauses (1) and (2) in connection with licenses granted solely to conduct development activities on behalf of the Buyer or any of its Affiliates) of a proposal that the Buyer license or otherwise grant to such third party any rights to develop or sell any CFTR MRT Product in any country or group of countries (a “License Opportunity”), or sell (other than through a change of control of the Buyer) all or a substantial portion of the Transferred Assets or other assets of the Buyer and its Affiliates that are necessary for or related to the development and commercialization of CFTR MRT Products (a “Sale Opportunity”; each License Opportunity for a CFTR MRT Product and each Sale Opportunity, an “Opportunity”) and (y) the board of directors of the Buyer directs the Buyer to pursue the Opportunity referenced in such proposal and (ii) prior to the Buyer or any of its Affiliates commencing negotiations with a third party with respect to an Opportunity. For clarity, this Section 1.11(k) shall not prevent the Buyer or any of its Affiliates from executing any confidentiality agreement or participating in general discussions with prospective partners, investors, licensors, licensees or other third parties, provided that such agreement or discussion does not relate to an Opportunity. The Seller shall have thirty (30) calendar days after receipt of the relevant ROFN Notice (the relevant “Notice Period”) to notify the Buyer in writing of its interest in negotiating an agreement with the Buyer with respect to the relevant Opportunity. If the Seller notifies the Buyer in writing within the Notice Period that it desires to negotiate such an agreement (a “Negotiation Notice”), then the Seller and the Buyer shall negotiate exclusively with respect to such Opportunity for up to ninety (90) calendar days after the Buyer’s receipt of such Negotiation Notice, which period may be extended by mutual written agreement of the parties

(the relevant “Negotiation Period”) and, for the avoidance of doubt, neither the Buyer nor any of its Affiliates shall negotiate with any third parties or enter into any agreements with respect to an Opportunity during the Notice Period or the Negotiation Period. If (x) the Seller does not notify the Buyer in writing within the relevant Notice Period that it desires to negotiate an agreement for such Opportunity, or (y) the parties fail within the Negotiation Period to reach agreement on and execute a definitive agreement for such Opportunity, then, for a period of twelve (12) months after the end of the Notice Period (if the Seller does not send a Negotiation Notice) or the end of the Negotiation Period (if the Seller does send a Negotiation Notice), the Buyer may thereafter grant the rights to such Opportunity to a third party on such terms as the Buyer may determine in its sole discretion, without any further obligation to the Seller under this Section 1.11(k) with respect to the Opportunity described in the relevant ROFN Notice, and, for clarity, during such applicable twelve (12) month period the Buyer shall have no obligation to again provide a ROFN Notice to the Seller with respect to such Opportunity; provided, however, that, during such twelve (12) month period, prior to entering into a definitive agreement with a third party with respect to such Opportunity, (1) the Buyer shall not enter into a period of exclusive negotiation with a third party for such Opportunity for a period in excess of ninety (90) days and (2) subject to clause (1), the Seller may continue to discuss such Opportunity with the Buyer.

1.12. Product Sale. In no event shall the Buyer or any of its Affiliates effect any Product Sale to any Person, unless such Product Sale is to a Qualified Transferee and all of the following requirements are satisfied: (a) such Qualified Transferee in such Product Sale agrees in writing to be bound by, and assumes and succeeds to, all of the obligations of the Buyer under this Agreement with respect to all MRT Compounds, MRT Products, Transferred Intellectual Property and Derived Patents that are the subject of such Product Sale, and (b) prior to or simultaneously with the consummation of such Product Sale, (i) such Qualified Transferee delivers to the Seller an instrument of assumption, reasonably acceptable to the Seller, effecting the agreement, assumption and succession described in the foregoing clause (a), and (ii) the Buyer pays or causes to be paid to the Seller all Contingent Payments that have become due and payable under this Agreement prior to such consummation of such Product Sale. Following the consummation of any such Product Sale effected in accordance with this Section 1.12, the Buyer shall be secondarily liable for any obligations of the Qualified Transferee under this Agreement with respect to the MRT Compounds, MRT Products, Transferred Intellectual Property and Derived Patents that are the subject of such Product Sale (it being understood that the Buyer will remain primarily liable for any obligations of the Buyer (and the Buyer Rights Group) under this Agreement in connection with any sale, transfer or license that is not a Product Sale). Notwithstanding anything in this Agreement to the contrary, (x) any purported Product Sale in contravention of this Section 1.12 shall be null and void and the Buyer shall remain solely liable for all obligations of the Buyer under this Agreement with respect to all MRT Compounds, MRT Products, Transferred Intellectual Property and Derived Patents that are the subject of such purported Product Sale, (y) nothing in this Section 1.12 shall be construed to reduce, limit or otherwise modify any liability of the Buyer under this Agreement with respect to any conduct of any member of the Buyer Rights Group, other than following the consummation of a Product Sale to a Qualified Transferee in accordance with this Section 1.12, and (z) nothing in this Section 1.12 shall be construed to reduce, limit or otherwise modify any of the Seller’s rights or the Buyer’s obligations under Section 1.11(k).

1.13. Unblocking Licenses.

(a) Effective as of the Closing, the Seller, on behalf of itself, Seller Parent and each of its controlled Affiliates, hereby grants to the Buyer a worldwide, non-exclusive, royalty-free, fully-paid up, perpetual, irrevocable, non-transferable (except in accordance with Section 6.4) license, sublicensable through multiple tiers (but subject to Section 1.13(c)), under the Seller Licensed IP to research, develop, manufacture, commercialize (e.g., sell and offer for sale), use and import any MRT Compound used in the MRT Program as of the Closing Date (“Buyer License”).

(b) Effective as of the Closing, the Buyer hereby grants to Seller Parent, the Seller and their respective Affiliates a worldwide, non-exclusive, royalty-free, fully-paid up, perpetual, irrevocable, non-transferable (except in accordance with Section 6.4) license, sublicensable through multiple tiers (but subject to Section 1.13(d)), under the Transferred Patents and Transferred Know-How to conduct research on, develop, manufacture, commercialize (e.g., sell and offer for sale), use and import any product (that is not a messenger RNA therapeutic product) for any purpose other than in connection with the MRT Program (“Seller License”).

(c) The license granted to the Buyer under the Buyer License shall include the right of the Buyer to grant sublicenses thereunder to any Person. The Buyer shall remain liable to the Seller for all acts or omissions of its sublicensees as if they were acts or omissions of the Buyer under this Agreement.

(d) The license granted to the Seller under the Seller License shall include the right of the Seller to grant sublicenses thereunder to any Person. The Seller shall remain liable to the Buyer for all acts or omissions of its sublicensees as if they were acts or omissions of the Seller under this Agreement.

(e) Without limiting the express representations and warranties of the parties set forth in Article II and Article III, the Buyer License and Seller License are granted “as is” and the Seller and the Buyer each hereby disclaim any express or implied representations or warranties of any kind with respect to the Buyer License and Seller License, including those regarding merchantability, fitness for a particular purpose or of non-infringement. Except for the Buyer License and Seller License, no other licenses of Intellectual Property are granted to the Buyer or the Seller under this Agreement.

(f) The terms and conditions of Section 4.1 shall apply to the Buyer, its Affiliates and sublicensees and their respective Representatives with respect to all confidential or non-public information included in any embodiment of the Seller Licensed IP provided to Buyer, mutatis mutandis (it being understood that, to the extent that any Seller Licensed IP is maintained as a trade secret by the Seller or any of its Affiliates, such terms and conditions shall survive and continue to apply to the Buyer, its Affiliates and sublicensees until such Seller Licensed IP is no longer maintained as a trade secret by the Seller or any of its Affiliates).

Subject to compliance with contractual obligations and applicable Law, following the Closing, each party shall afford to the other party and the other party’s Representatives during normal business hours in a manner so as to not unreasonably disrupt or interfere with the conduct of business (a) reasonable access and duplicating rights to all Confidential Information (which shall remain subject to Section 4.1, as applicable) and other information relating to the MRT Program within the possession or control of such party and (b) reasonable access to the personnel of such party related to the MRT Program, in each case in connection with its financial reporting and accounting matters, preparing financial statements, preparing and filing any Tax Returns, prosecuting any claims for refund, defending any Tax claims or assessment, preparing securities Law or securities exchange filings, prosecuting, defending or settling any litigation or insurance claim, prosecuting patent applications and pursuing other patent matters, performing obligations under this Agreement and the Ancillary Agreements and all other proper business purposes (including determining any matter relating to its rights and obligations hereunder). A party making information or personnel available to another party under this Section 4.2 shall be entitled to receive from such other party, upon the presentation of invoices therefor, payments for such amounts relating to supplies, disbursements and other out-of-pocket expenses, as may reasonably be incurred in making such information or personnel available; provided, however, that no such reimbursements shall be required for general overhead or the salary or cost of benefits or similar expenses pertaining to employees of the providing party. Notwithstanding anything to the contrary contained herein, nothing in this Section 4.2 shall require (i) the Seller or any of its Affiliates or the Buyer or any of its Affiliates (x) to waive the protection of an attorney-client privilege, (y) to violate applicable Law or (z) to take any action that would result in the disclosure of any trade secrets (for the avoidance of doubt, without limitation of the Seller’s obligation to provide the Buyer with the Transferred Assets as provided hereunder and the services under the Transition Services Agreement) (provided that, in the case of clauses (i)(x) and (i)(y), the disclosing party shall use commercially reasonable efforts to provide the other party, to the extent possible, with access to the relevant information in a manner that would not reasonably be expected to result in any such violation or waiver) or (ii) the auditors and independent accountants of the Seller or any of its Affiliates or of the Buyer or any of its Affiliates to make any work papers available to any Person unless and until such Person has signed a customary confidentiality and hold harmless agreement relating to such access to work papers in form and substance reasonably acceptable to such auditors or independent accountants. The parties acknowledge that, with respect to e-mails, (i) the Buyer shall solely be entitled to request, based on a specific keyword search, any e-mails of the Business Employees since [**] that are exclusively related to the MRT Program and are Excluded Assets, (ii) any e-mails provided to the Buyer pursuant to this Section 4.2 shall require the assistance of a third-party vendor to review and provide such e-mails and the Buyer shall be responsible to pay any costs and expenses incurred by the Seller related thereto and (iii) Shire shall only be required to retain such e-mails for [**] from their respective delivery dates.

4.3. Public Disclosure. The press release announcing the execution of this Agreement shall be issued in such form as shall be mutually agreed upon by the Seller and the Buyer. Unless otherwise required by applicable Law, by any listing agreement with any U.S. or U.K. securities exchange or share market or by any listing authority including the U.K. Listing Authority, the Seller and the Buyer shall not, and cause their respective controlled Affiliates not to, make any public announcement or publicly disseminate any written communication with respect to this Agreement or the Contemplated Transactions, or otherwise communicate with

any news media regarding this Agreement or the Contemplated Transactions, without the prior written consent of the other party; provided that if any such announcement or communication is so required, the Buyer and the Seller shall consult with each other, to the extent reasonably practicable, in advance as to the contents and timing thereof; provided, further, (a) that after the Contemplated Transactions have been announced, Seller Parent, the Seller and their controlled Affiliates and the Buyer and its controlled Affiliates shall be entitled to respond to questions in the ordinary course or issue any press release or make any other public statement that, in each case, is not inconsistent with any public statement previously issued or made by it in accordance with the provisions of this Section 4.3 , and (b) nothing in this Agreement, but subject to Section 1.13(f), shall restrict the Buyer or any member of the Buyer Rights Group from making any public announcement or from publicly disseminating any written communication with respect to the research, development, manufacture or commercialization of any MRT Compound or MRT Product or the exploitation of any Transferred Asset that is not related to the Contemplated Transactions.

4.4. Nonsolicitation.

(a) The Seller covenants and agrees that from and after the Closing Date and until the [**] of the Closing Date, the Seller shall not, and shall cause Seller Parent and its controlled Subsidiaries not to, directly or indirectly, hire or solicit any Business Employee who is given an offer of employment by the Buyer in accordance with the terms of Section 4.7 (an “Offered Employee”) or encourage any Offered Employee to leave his or her employment or hire any Offered Employee who has left such employment; provided, however, that a general solicitation which is not directed specifically to Offered Employees, and the hiring of an Offered Employee through such general solicitation, shall not be deemed a violation hereof and provided, further, that nothing in this Section 4.4(a) shall apply to the hiring of (i) an Offered Employee whose employment with the Buyer has been terminated for a period of at least [**] or (ii) an Offered Employee who approached the Seller for employment on an unsolicited basis.

(b) The Buyer covenants and agrees that from and after the Closing Date and until the [**] of the Closing Date, the Buyer shall not, and shall cause its controlled Subsidiaries not to, directly or indirectly, hire or solicit any employees of Seller Parent or any of its Subsidiaries that (i) are related to the MRT Program or (ii) the Buyer had contact with or obtained information about in connection with the Contemplated Transactions (each, a “Seller Employee”) or encourage any Seller Employee to leave his or her employment or hire any Seller Employee who has left such employment; provided, however, that a general solicitation which is not directed specifically to Seller Employees, and the hiring of a Seller Employee through such general solicitation, shall not be deemed a violation hereof and provided, further, that nothing in this Section 4.4(b) shall apply to the hiring of (i) a Seller Employee whose employment with Seller Parent or any of its Subsidiaries has been terminated for a period of at least [**] or (ii) a Seller Employee who approached the Buyer for employment on an unsolicited basis.

(c) The parties acknowledge that the covenants set forth in this Section 4.4 are an essential element of this Agreement and that, but for these covenants, the parties would not have entered into this Agreement. The parties acknowledge that this Section 4.4 constitutes an independent covenant and shall not be affected by performance or nonperformance of any other provision of this Agreement or any other document contemplated

by this Agreement and the Ancillary Agreements. The Seller, on behalf of itself, Seller Parent and its controlled Subsidiaries, acknowledges and agrees that, in the event that the Seller, Seller Parent or one or more of its controlled Subsidiaries breaches any of the provisions in this Section 4.4, the Buyer shall suffer immediate, irreparable injury and will, therefore, be entitled to seek injunctive relief, without the requirement of posting any bond or other security, in addition to any other damages to which it may be entitled, as well as reimbursement by the Seller of the reasonable costs and attorneys’ fees the Buyer incurs in successfully enforcing its rights under this Section 4.4. The Buyer, on behalf of itself and its controlled Affiliates, acknowledges and agrees that, in the event that the Buyer or one or more of its controlled Affiliates breaches any of the provisions in this Section 4.4, the Seller shall suffer immediate, irreparable injury and will, therefore, be entitled to seek injunctive relief, without the requirement of posting any bond or other security, in addition to any other damages to which it may be entitled, as well as reimbursement by the Buyer of the reasonable costs and attorneys’ fees the Seller incurs in successfully enforcing its rights under this Section 4.4.

(d) The parties acknowledge that the restrictions set forth in this Section 4.4 (i) are reasonably drawn with respect to duration, scope, and otherwise, (ii) are not unduly burdensome, (iii) are not injurious to the public interest and (iv) are supported by adequate consideration. It is the intention of the parties that if any of the restrictions or covenants contained in this Section 4.4 is held to cover a geographic area or to be for a length of time which is not permitted by applicable Law, or in any way construed to be too broad or to any extent invalid, such restrictions or covenants shall not be construed to be null, void and of no effect, but to the extent such restrictions or covenants would be valid or enforceable under applicable Law, a court of competent jurisdiction shall construe and interpret or reform this Section 4.4 to provide for a covenant having the maximum enforceable geographic area, time period and other provisions that would be valid and enforceable under such applicable Law. The parties agree and intend that the applicable obligations under this Section 4.4 be tolled during any period that a breaching party is finally determined to be in breach of any of the obligations under this Section 4.4, so that the non-breaching party is provided with the full benefit of the restrictive periods set forth herein.

4.5. Other Actions. Except as set forth on Section 4.5 of the Seller Disclosure Schedule, the parties acknowledge that after the Closing, as between the parties, the Buyer will have full control of all pending patent applications and prosecution thereof, issued patents and maintenance thereof, in each case, to the extent included in the Transferred Patents, and, at the Buyer’s request, the Seller will execute and deliver at Closing all documents reasonably necessary to effect the same.

4.6. Further Assurances. Each of the parties will execute and deliver any further instruments and documents as any other party reasonably may request in order to carry out the purposes of this Agreement or any Ancillary Agreement.

4.7. Employees.

(a) Offers of Employment. Not less than [**] prior to the Closing Date, the Buyer (or one of its controlled Subsidiaries) shall make an offer of at-will employment, to be effective as of the Closing Date, to each Business Employee who is employed by the Seller

immediately prior to the Closing Date (excluding any such Business Employee who is on disability or other approved leave of absence and does not return to active employment within [**] following the Closing); provided that any Business Employee who is not in active employment on the Closing Date due to disability or other approved leave of absence shall become an employee of the Buyer only upon returning to active employment. Each such offer of at-will employment shall be on terms and conditions no less favorable than those provided in this Section 4.7. Each Business Employee who accepts such offer of employment shall be deemed a “Transferred Employee” on the date such employee commences active employment with the Buyer or one of its Subsidiaries.

(b) Employee Compensation and Benefits. (i) For a period of at least [**] commencing on the Closing Date (the “Continuation Period”), the Buyer shall provide, or shall cause its Affiliates to provide, each Transferred Employee who remains employed by the Buyer following the Closing Date with (w) a base salary or wage rate, bonus opportunity and severance payments and benefits that are no less favorable than the base salary or wage rate (which such base salary or wage rate will be eligible for increase in accordance with the Buyer’s 2017 merit increase program), bonus opportunity (including, if applicable, a one-time bridge payment, rounded to the next $[**], in respect of the 2017 annual bonus target payable to each affected Transferred Employee on the first anniversary of such Transferred Employee’s employment with the Buyer) and severance payments and benefits that are provided by the Seller to such Transferred Employee immediately prior to the Closing Date, (x) except as agreed between the parties, at least [**] of paid vacation (it being understood that the Buyer shall accelerate its vacation benefit for 2017), (y) equity incentive compensation commensurate with industry standards and (z) subject to Section 4.7(d), other employee benefits (other than nonqualified pension benefits and deferred compensation) that are substantially comparable in the aggregate to the employee benefits provided to such Transferred Employee immediately prior to the Closing Date (other than nonqualified pension benefits and deferred compensation).

(ii) With respect to any employee benefit plan maintained by the Buyer or its Affiliates in which any Transferred Employee becomes a participant, for purposes of determining eligibility to participate, vesting, vacation, paid time-off and severance plan and other benefit plan accruals, each Transferred Employee’s service with the Seller or any of its Affiliates (as well as service with any predecessor employer, to the extent recognized by the Seller or any of its Affiliates) shall be treated as service with the Buyer and its Affiliates; provided, however, that such service need not be recognized (x) to the extent that such recognition would result in any duplication of benefits or (y) such service was not recognized under a comparable Employee Plan immediately prior to the Closing or (z) for any purposes in connection with equity awards.

(iii) The Buyer shall use reasonable best efforts to waive, or shall cause its Affiliates to waive, any preexisting conditions, limitations, exclusions, actively at work requirements and waiting periods under any welfare benefit plan maintained by the Buyer or any of its Affiliates in which Transferred Employees (and their eligible dependents) will be eligible to participate from and after the Closing, except to the extent that such items would not have been satisfied or waived under the comparable Employee Plan immediately prior to the Closing. Where a waiting period cannot be waived, the Buyer will cover the costs of employee COBRA coverage for the duration of the intervening period. The Buyer shall use reasonable

best efforts to recognize, or shall cause its Affiliates to recognize, all co-payments, deductibles and similar expenses and out-of-pocket maximums incurred by each Transferred Employee (and his or her eligible dependents) prior to the Closing during the plan year in which Closing occurs for purposes of satisfying any comparable deductible and co-payment limitations and out-of-pocket requirements under the relevant welfare benefit plans in which such Transferred Employee (and his or her eligible dependents) will be eligible to participate from and after the Closing during the plan year in which Closing occurs.

(iv) Effective as of the Closing Date, the vesting of each unvested Seller equity award held by any Transferred Employee immediately prior to the Closing Date shall, by virtue of the consummation of the Contemplated Transactions and without any action on the part of the holder thereof, be accelerated on a pro-rata basis through the Closing Date consistent with the Seller’s approved Good Leaver treatment of equity awards. These equity awards will become vested and, to the extent applicable, exercisable under the terms of the Sellers long-term incentive plan rules under which they were granted.

(v) To the extent that a Transferred Employee remains employed by the Buyer on the [**] of the Closing Date, the Buyer shall provide such Transferred Employee with a payment in cash equal to the amount set forth opposite such Transferred Employee’s name on Schedule 4.7(b)(v), less applicable Tax withholding.

(c) Flexible Spending Account Plan. Effective as of the Closing Date or as soon as administratively practicable thereafter, the Buyer (or one of its Subsidiaries) shall cause the flexible spending account plan under Section 125 of the Code sponsored by the Buyer (the “Buyer FSAP”) to assume the account balances associated with the Transferred Employees’ flexible spending accounts under the comparable plan of the Seller (the “Seller FSAP”). The Buyer FSAP will recognize the elections that each Transferred Employee had in effect under the Seller FSAP, subject to the applicable dollar limits of the Buyer FSAP for the calendar year in which such Transferred Employee becomes covered under the Buyer FSAP. The Buyer FSAP shall be responsible for reimbursement of all previously unsubmitted and unreimbursed medical and dependent care claims incurred by the Transferred Employees in such calendar year. As part of the Buyer’s assumption of the Transferred Employees’ flexible spending accounts under the Seller FSAP, the Seller (or one of its Affiliates) shall transfer to the Buyer FSAP a cash amount equal to the aggregate net positive balance, if any, of all accounts assumed by the Buyer FSAP under this Section 4.7(c), as of the date of assumption by the Buyer (or one of its Affiliates).

(d) Defined Contribution Plan. As soon as practicable after the Closing Date, account balances as of the Closing Date of the Transferred Employees in the Shire Pharmaceuticals Inc. 401(k) Savings Plan (the “Seller Defined Contribution Plan”), including any outstanding participant loans, shall be transferred to a qualified defined contribution plan of the Buyer or one of its Affiliates. Such transfer shall be effected in accordance with Applicable Law and the Buyer shall make or cause to be made, and the Seller shall make or cause to be made, any required filings in connection therewith. The parties hereby agree to cooperate in good faith to provide for the duration of the Continuation Period to each Transferred Employee who participates in the Seller Defined Contribution Plan with a matching contribution that is no less favorable than the matching contribution provided by the Seller to such Transferred

Employee immediately prior to the Closing Date; provided that if such matching contribution made by the Buyer is less favorable, the Buyer shall provide such affected Transferred Employee with a one-time cash payment equal to the difference (on an after-tax basis) between the matching contribution provided by the Buyer and the matching contribution that would have been provided by the Seller to such Transferred Employee under the Seller Defined Contribution Plan.

(e) 2016 Annual Bonuses. Annual bonuses for the year in which the Closing occurs shall be treated in accordance with the terms set forth in Section 4.7(e) of the Seller Disclosure Schedule.

(f) Work Authorization. The Buyer will continue to sponsor and provide assistance in connection with obtaining and/or maintaining, as applicable, appropriate work authorization in the United States for any Transferred Employee requiring such authorization.

(g) This Section 4.7 shall be binding upon and inure solely to the benefit of the parties to this Agreement, and nothing in this Section 4.7, express or implied, (i) is intended to confer upon any other Person, including any Business Employee, any rights or remedies of any nature whatsoever under or by reason of this Section 4.7 and (ii) shall limit the right of the parties to this Agreement to terminate the employment of any Person, including any Business Employee, at any time following the Closing.

4.8. Financing.

(a) At or prior to the Closing, the Buyer shall consummate an Equity Financing with gross proceeds of at least Fifty Million Dollars ($50,000,000) (the “First Tranche”) and, if such gross proceeds are less than One Hundred Million Dollars ($100,000,000), the Buyer shall use the first Fifty Million Dollars ($50,000,000) of the net proceeds from the First Tranche (the “Specified Proceeds”) solely for activities and expenses associated with the MRT Program and/or the Transferred Assets (including employee compensation and benefits expenses, rent and overhead expenses, purchases and maintenance of capital equipment and other costs and expenditures, which costs and expenses may be comprised of intercompany or intracompany allocations of corporate or other overhead) and to satisfy the Buyer’s obligations hereunder or under the Ancillary Agreements until the earlier of (i) the consummation of another tranche or tranches of Equity Financing with aggregate gross proceeds equal to at least (A) One Hundred Million Dollars ($100,000,000) minus (B) the gross proceeds from the First Tranche (each such tranche, a “Subsequent Tranche”) and (ii) full utilization of the Specified Proceeds in accordance with this Section 4.8(a).

(b) If the gross proceeds from the First Tranche are less than One Hundred Million Dollars ($100,000,000), the Buyer shall use commercially reasonable efforts to consummate Subsequent Tranches (each, a “Subsequent Tranche Closing”) as promptly as practicable until proceeds from the First Tranche and all Subsequent Tranches is equal to or greater than One Hundred Million Dollars ($100,000,000) (and shall not permit the consummation of a financing by a controlled Affiliate of the Buyer or a holding company of the Buyer in order to avoid the Buyer’s obligations in this Section 4.8(b), including by raising

financing at a holding company or Subsidiary of the Buyer or by issuing securities that are not convertible into or exchangeable for Buyer Common Stock). At each Subsequent Tranche Closing, the Buyer shall deliver to the Seller a certificate representing a number of shares of Buyer Common Stock equal to the applicable Subsequent Tranche Closing Date Consideration.

(c) Upon issuance of the Stock Fee (as defined in the Engagement Letter) to MTS, the Buyer shall deliver to the Seller a certificate representing a number of shares of Buyer Common Stock in an amount necessary so that the aggregate ownership percentage of outstanding Buyer Common Stock (determined on an as-converted basis) of Seller Parent and its controlled Affiliates is not affected by the issuance of the Stock Fee.

4.9. Seller Names and Marks.

Following the Closing, Buyer shall, and shall cause its controlled Affiliates to, cease and discontinue any and all uses of the Seller Names and Marks and remove all Seller Names and Marks from the Transferred Assets and any other materials of Buyer or any of its controlled Affiliates.

4.10. Tax Matters.

(a) The Buyer and the Seller agree to furnish or cause to be furnished to each other, upon request, as promptly as practicable, such information and assistance relating to the Transferred Assets (including access to books and records) as is reasonably necessary for the filing of all Tax Returns, the making of any election relating to Taxes, the preparation for any audit by any Governmental Entity, and the prosecution or defense of any claim, suit or proceeding relating to any Tax. The Buyer and the Seller (and their respective Subsidiaries) shall retain all books and records with respect to Taxes pertaining to the Transferred Assets for a Pre-Closing Tax Period for a period of at least six years following the Closing Date. On or after the end of such period, each party shall provide the other with at least 10 days prior written notice before destroying any such books and records, during which period the party receiving such notice can elect to take possession, at its own expense, of such books and records. The Seller and the Buyer shall cooperate with each other in the conduct of any audit or other proceeding relating to Taxes involving the Transferred Assets with respect to any Pre-Closing Tax Period.

(b) Any real property, personal property or similar Taxes applicable to the Transferred Assets for a taxable period that includes but does not end on the Closing Date (collectively, the “Apportioned Obligations”) shall be paid by the Buyer or the Seller, as applicable, and such Taxes shall be apportioned between the Buyer and the Seller based on the number of days in such taxable period included in the Pre-Closing Tax Period and the number of days in the entire taxable period. The Seller shall pay the Buyer an amount equal to any such Taxes payable by the Buyer which are attributable to the Pre-Closing Tax Period, and the Buyer shall pay the Seller an amount equal to any such Taxes payable by the Seller which are not attributable to the Pre-Closing Tax Period. Such payments shall be made on or prior to the Closing Date or, if later, on the date such Taxes are due (or thereafter, promptly after request by the Buyer or the Seller if such Taxes are not identified by the Buyer or the Seller on or prior to the Closing Date). Apportioned Obligations shall be timely paid, and all applicable filings, reports and returns shall be filed, as provided by applicable Law.

4.11. Books and Records.

From and after the Closing, subject to Section 4.1, Seller Parent, the Seller and their controlled Affiliates and its and their respective Representatives may retain a copy of any or all of the data room materials and other books, data, files, information and records relating to the MRT Program on or before the Closing Date. Each party agrees that, with respect to all original data room materials and other books, data, files, information and records relating to the MRT Program and existing as of the Closing, it will (and will cause each of its controlled Affiliates and Representatives to) (i) comply in all material respects with all applicable Law relating to the preservation and retention of records and (ii) apply preservation and retention policies that are no less stringent than those generally applied by such party or its controlled Affiliates or Representatives. In addition, for at least three years after the Closing Date, the Buyer shall, and shall cause each of its controlled Affiliates to, preserve all original data room materials and other books, data, files, information and records relating to the MRT Program and existing as of the Closing Date and, thereafter, until the [**] of the Closing Date, dispose of such original data room materials and other books, data, files, information and records only after it shall have given the Seller [**] prior written notice of such disposition and the opportunity (at the Seller’s expense) to remove and retain such information.

4.12. Services from Affiliates.

The Buyer acknowledges that the MRT Program currently receives from the Seller and its Affiliates certain services and benefits, including IT services and the benefit of the use of IT assets of the Seller and its Affiliates. Other than as may be provided pursuant to the terms of the Transition Services Agreement, the Buyer further acknowledges and agrees that all such services and benefits shall cease, and any agreement in respect thereof shall terminate with respect to the MRT Program as of the Closing, and thereafter the sole obligation of the Seller and its Affiliates with respect to the provision of any services with respect to the MRT Program shall be as set forth in the Transition Services Agreement. The foregoing shall in no way limit the express representations or warranties of the Seller contained in Article II, including representations or warranties in Section 2.13.

4.13. Equity Ceiling. From and after the Closing, the Buyer agrees not to take, and agrees to prevent its controlled Affiliates from taking, any actions that would result in Seller Parent, together with Seller and their respective controlled Affiliates, beneficially owning (within the meaning of Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended) Buyer Stock representing in excess of 19.9% of the voting power of all outstanding Buyer Stock (excluding from the denominator unvested restricted stock) (the “Threshold”). In the event of Seller Parent, together with Seller and their respective controlled Affiliates, beneficially owning Buyer Stock in excess of the Threshold, at the Seller’s written election the Buyer agrees to promptly redeem shares of Buyer Stock from Seller Parent, the Seller and their respective controlled Affiliates at the then-fair market value of such shares such that Seller Parent, Seller and their respective controlled Affiliates cease to beneficially own Buyer Stock in the aggregate in excess of the Threshold; provided, however, that such obligation to redeem such shares of

Buyer Stock shall not apply after the consummation of the first underwritten public offering of the Buyer Common Stock under the Securities Act to the extent the Seller and/or its controlled Affiliates can sell such excess shares without limitation pursuant to Rule 144 promulgated under the Securities Act.

4.14. Letter of Credit. As promptly as practicable and in any event within four weeks after the date hereof, the Buyer shall secure an irrevocable standby letter of credit for the benefit of the Seller in an amount equal to $[**], in form and substance reasonably acceptable to the Seller, which shall be available until [**] to be drawn by the Seller against any Liability incurred by the Seller under the Lease.

4.15. No Impairment.

(a) The Buyer shall not, and shall not permit any of its controlled Affiliates to, amend its or its controlled Affiliates’ organizational documents in a manner that avoids, or seeks to avoid, any of the terms and conditions of, or the ability of the Buyer or such controlled Affiliate(s) to observe or perform any of the terms or conditions of, this Agreement or the Ancillary Agreements. The Buyer shall provide the Seller with prior written notice of any proposed amendment to such organizational documents at least [**] prior to the amendment thereof.

(b) The Buyer acknowledges that in the event that the Buyer or one or more of its controlled Affiliates breaches any of the provisions in Section 4.15, the Seller and its Affiliates shall suffer immediate, irreparable injury and will, therefore, be entitled to injunctive relief, without the requirement of posting any bond or other security, in addition to any other damages to which it may be entitled, as well as reimbursement by the Buyer of the reasonable costs and attorneys’ fees the Buyer incurs in successfully enforcing its rights under Section 4.15.

ARTICLE V

5.1. Indemnification by the Seller. Subject to the terms and conditions of this Article V, from and after the Closing, the Seller shall defend and indemnify the Buyer, its Affiliates and their respective Representatives (collectively, the “Buyer Indemnified Parties”) in respect of, and hold them harmless against and will compensate and reimburse them for, any and all Damages suffered or incurred by any of them (whether or not such Damages relate to any Third Party Action) resulting from, arising out of or constituting:

(a) any inaccuracy in or breach of any of the representations or warranties of the Seller contained in Article II of this Agreement;

(b) any breach or failure to perform by the Seller of any covenant or agreement contained in this Agreement; or

5.2. Indemnification by the Buyer. Subject to the terms and conditions of this Article V, from and after the Closing, the Buyer shall defend and indemnify the Seller, its Affiliates and their respective Representatives (collectively, the “Seller Indemnified Parties”) in respect of, and hold them harmless against and will compensate and reimburse them for, any and all Damages suffered or incurred by any of them (whether or not such Damages relate to any Third Party Action) resulting from, arising out of or constituting:

(a) any inaccuracy in or breach of any of the representations or warranties of the Buyer contained in Article III of this Agreement;

(b) any breach or failure to perform by the Buyer of any covenant or agreement contained in this Agreement;

(d) the Incorporation.

5.3. Claims for Indemnification.

(a) Third Party Claims. All claims for indemnification made under this Agreement resulting from, related to or arising out of a third party claim against an Indemnified Party (a “Third Party Claim”) shall be made in accordance with the following procedures. A Person entitled to indemnification under this Article V (an “Indemnified Party”) shall give prompt written notification to the Indemnifying Party (a “Third Party Claim Notice”) of the commencement of any action, suit or proceeding relating to a third party claim for which indemnification may be sought or, if earlier, upon the assertion of any such claim by a third party. For purposes of this Agreement, “Indemnifying Party” means (i) in the case of a claim for indemnification by the Buyer (or any other Buyer Indemnified Party), the Seller, and (ii) in the case of a claim for indemnification by the Seller (or any other Seller Indemnified Party), the Buyer. Such Third Party Claim Notice shall include a description in reasonable detail (to the extent then known by the Indemnified Party) of (A) the facts constituting the basis for such Third Party Claim and (B) the amount of the Damages claimed (the “Third Party Claim Amount”). No delay or failure on the part of the Indemnified Party in so notifying the Indemnifying Party shall relieve the Indemnifying Party of any liability or obligation hereunder except to the extent the Indemnifying Party is actually prejudiced thereby. Within [**] after receipt of such Third Party Claim Notice, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense with counsel reasonably satisfactory to the Indemnified Party of any such Third Party Claim seeking (i) solely monetary damages or (ii) injunctive relief that would be reasonably expected to be immaterial to the operations or business of the Indemnified Party and monetary damages; provided that prior to the assumption of the defense of any Third Party Claim, the Indemnifying Party shall provide a written undertaking confirming that as between the Indemnified Party and the Indemnifying Party, assuming the facts alleged in such Third Party Claim are true, that it would have been an indemnity obligation for Damages resulting from such Third Party Claim (subject to the limitations set forth herein). If the Indemnifying Party does not assume control of such defense, the Indemnified Party shall control such defense. The party not controlling such defense may participate therein at its own expense; provided that if the Indemnifying Party assumes control of such defense and the Indemnified

Party reasonably concludes, based on advice from outside counsel, that the Indemnifying Party and the Indemnified Party have conflicting interests with respect to such action, suit, proceeding or claim, the reasonable fees and expenses of counsel to the Indemnified Party solely in connection therewith shall be considered “Damages” for purposes of this Agreement; provided, however, that in no event shall the Indemnifying Party be responsible for the fees and expenses of more than one (1) counsel for the Indemnified Party. The party controlling such defense shall keep the other party reasonably advised of the status of such action, suit, proceeding or claim and the defense thereof. The Indemnified Party shall not agree to any settlement of such action, suit, proceeding or claim without the prior written consent of the Indemnifying Party. The Indemnifying Party shall not agree to any settlement of such action, suit, proceeding or claim that (x) does not include a complete release of the Indemnified Party from all liability with respect thereto, (y) includes any admission by, or finding adverse to, the Indemnified Party or (z) imposes any liability or obligation on the Indemnified Party, in each case, without the prior written consent of the Indemnified Party (not to be unreasonably withheld, conditioned or delayed).

(b) Procedure for Claims Not Involving Third Parties. An Indemnified Party wishing to assert a claim for indemnification under this Article V that does not involve a Third Party Claim shall deliver to the Indemnifying Party a written notice (a “Claim Notice”) which contains (i) a description and the amount (the “Claim Amount”) of any Damages, (ii) a statement that the Indemnified Party is entitled to indemnification under this Article V and a reasonable explanation of the basis therefor and (iii) a demand for payment in the amount of such Damages. The Indemnifying Party shall deliver to the Indemnified Party a written response in which the Indemnifying Party shall (A) agree that the Indemnified Party is entitled to receive all of the Claim Amount, (B) agree that the Indemnified Party is entitled to receive part, but not all, of the Claim Amount or (C) contest that the Indemnified Party is entitled to receive any of the Claim Amount.

With respect to any Damages that may be recoverable by an Indemnified Party under Section 5.1(a) or Section 5.2(a), other than in respect of the Core Reps, neither the Seller nor the Buyer shall be liable for any individual or series of related Damages which do not exceed $[**] (which Damages shall not be counted toward the Deductible).

(d) Except with respect to claims for actual and knowing common law fraud or for specific performance as provided in Section 6.9, from and after the Closing the rights of the Indemnified Parties under this Article V shall be the sole and exclusive remedies of the Indemnified Parties with respect to claims under, or otherwise relating to the transactions that are the subject of, this Agreement (whether at law or in equity and regardless of the legal theory

under which such claim may be made). Without limitation of the foregoing, in no event shall any party, its successors or permitted assigns be entitled to claim or seek rescission of the Contemplated Transactions.

(e) Notwithstanding anything to the contrary in this Agreement, for purposes of determining the amount of Damages for which any Buyer Indemnified Party or Seller Indemnified Party may be entitled to indemnification under this Article V (but not for the purposes of determining whether there has been a breach of any representation or warranty set forth in Article II or Article III), each such representation or warranty shall be deemed to have been made without any qualifications or limitations as to materiality (including any qualifications or limitations made by reference to a Seller Material Adverse Effect or Buyer Material Adverse Effect).

(f) Any payment by the Seller to satisfy its indemnification obligations under this Article V may be made, at the option of the Seller, in cash or by surrendering shares of Buyer Common Stock to the Buyer, which shares shall be valued at $1.98 per share (adjusted as may be appropriate to account for any stock split, combination, recapitalization or similar event, the “Per Share Value”).

5.6. Indemnification Payments. All indemnification payments made hereunder shall be treated by all parties as adjustments to the Aggregate Consideration for Tax purposes unless otherwise required by Law.

5.7. Setoff.

Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one (1) remedy will not preclude the exercise of any other remedy.
