Homology shall further take all actions necessary so that the certificate of incorporation of Homology shall remain in effect following the Effective Time, until thereafter amended as provided by Delaware Law, provided, however, that at or prior to the Effective Time, Homology shall file one or more amendments to its certificate of incorporation to (i) change the name of Homology to Q32 Bio Inc., (ii) effect the Nasdaq Reverse Split and the Authorized Share Increase Proposal and (iii) make such other changes as are mutually agreeable to Homology and Q32.

(b) Bylaws. The bylaws of the Surviving Corporation shall be amended and restated as of the Effective Time to be the same as the bylaws of Merger Sub as in effect immediately prior to the Effective Time (with the name of Q32 as the Surviving Corporation’s name) until thereafter amended in accordance with Delaware Law and as provided in the Surviving Corporation’s Organizational Documents.

(c) Directors and Officers. The directors and officers, each to hold office in accordance with the provisions of Delaware Law and the Surviving Corporation’s Organizational Documents immediately after the Effective Time, shall be as set forth in Section 5.19.

2.4 Conversion of Shares.

(a) At the Effective Time (after giving effect to Q32 Preferred Stock Conversion), by virtue of the Merger and without any further action on the part of Homology, Merger Sub, Q32 or any stockholder of Q32, subject to Section 2.4(d), the Q32 Common Stock outstanding immediately prior to the Effective Time (excluding Q32 Common Stock issued in the Concurrent Financing) shall be converted solely into the right to receive a number of shares of Homology Common Stock equal to the amount of Q32 Merger Shares multiplied by the applicable stockholder’s percentage interest in Q32 as set forth on the Allocation Certificate.

(b) At the Effective Time, by virtue of the Merger and without further action on the part of Homology, Merger Sub, Q32 or any stockholder of Q32, subject to Section 2.4(d), the Q32 Common Stock issued in the Concurrent Financing shall be converted solely into the right to receive a number of shares of Homology Common Stock equal to the amount of Concurrent Financing Merger Shares multiplied by the percentage of the Concurrent Financing Proceeds represented by the applicable stockholder’s investment in the Concurrent Financing, as set forth on the Allocation Certificate.

(c) If any Q32 Common Stock outstanding immediately prior to the Effective Time is unvested or is subject to a repurchase option or a risk of forfeiture under any applicable restricted stock, restricted stock unit award agreement or other similar agreement with Q32, then the shares of Homology Common Stock issued in exchange for such Q32 Common Stock will to the same extent be unvested and subject to the same repurchase option or risk of forfeiture, and such shares of Homology Common Stock shall accordingly be marked with appropriate legends. Q32 shall take all actions that may be necessary to ensure that, from and after the Effective Time, Homology is entitled to exercise any such repurchase option or other right set forth in any such restricted stock unit award agreement or other agreement.

(d) No fractional shares of Homology Common Stock shall be issued in connection with the Merger, and no certificates or scrip for any such fractional shares shall be issued, with no cash being paid for any fractional share eliminated by such rounding. Any fractional shares of Homology Common Stock a holder of Q32 Common Stock would otherwise be entitled to receive shall be aggregated together first prior to eliminating any remaining fractional share.

(e) At the Effective Time, by virtue of the Merger and without any further action on the part of Homology, Merger Sub, Q32 or any stockholder of Q32, each share of common stock, $0.01 par value per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of common stock, $0.0001 par value per share, of the Surviving Corporation. If applicable, each stock certificate of Merger Sub evidencing ownership of any such shares shall, as of the Effective Time, evidence ownership of such shares of common stock of the Surviving Corporation until presented for transfer or exchange.

(f) If, between the date of this Agreement and the Effective Time, the outstanding Q32 Common Stock or Homology Common Stock shall have been changed into, or exchanged for, a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split (including the Nasdaq Reverse Split to the extent such split has not previously been taken into account in calculating Q32 Merger Shares), combination or exchange of shares or other like change, Q32 Merger Shares shall, to the extent necessary, be equitably adjusted to reflect such change to the extent necessary to provide the holders of Q32 Common Stock and Homology Common Stock with the same economic effect as contemplated by this Agreement prior to such stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares or other like change; provided, however, that nothing herein will be construed to permit Q32 or Homology to take any action with respect to Q32 Common Stock or Homology Common Stock, respectively, that is prohibited or not expressly permitted by the terms of this Agreement.

(g) Each Q32 Option outstanding immediately prior to the Effective Time shall automatically without any further action on the part of Homology, Merger Sub, Q32 or any holder of a Q32 Option, be converted, at the Effective Time, into an option (an “Assumed Option”) to acquire, on the same terms and conditions (including the same vesting and exercisability terms and conditions) as were applicable under the Q32 Equity Plan and option agreement applicable to such Q32 Option immediately prior to the Effective Time, the number of shares of Homology Common Stock determined by multiplying the number of shares of Q32 Common Stock subject to such Q32 Option immediately prior to the Effective Time by the Q32 Exchange Ratio, rounding down to the nearest whole number of shares, at a per share exercise price determined by dividing the per share exercise price of such Q32 Option immediately prior to the Effective Time by the Q32 Exchange Ratio, rounding up to the nearest whole cent; provided, that the conversion of the Q32 Options will be made in a manner consistent with

Treasury Regulations Section 1.424-1, such that the conversion will not constitute a “modification” of such Q32 Options for purposes of Section 409A or Section 424 of the Code. As of the Effective Time, Homology will assume the Q32 Equity Plan.

(h) All Q32 Preferred Stock shall be converted into Q32 Common Stock as of immediately prior to the Effective Time in accordance with, and pursuant to the terms and conditions of, the Organizational Documents of Q32 (the “Q32 Preferred Stock Conversion”).

(i) At the Effective Time, each Q32 Warrant, to the extent outstanding and unexercised, shall automatically, without any action on the part of the holder thereof, be converted into a warrant to acquire a number of shares of Homology Common Stock(each such resulting warrant, an “Assumed Warrant”). Each Assumed Warrant shall be subject to the same terms and conditions as were applicable to such corresponding Q32 Warrant immediately prior to the Effective Time (including applicable vesting conditions), except (i) each Assumed Warrant will be exercisable (or will become exercisable in accordance with its terms) for that number of whole shares of Homology Common Stock equal to the product of the number of Q32 Merger Shares that were issuable upon exercise of such Q32 Warrant immediately prior to the Effective Time multiplied by the Q32 Exchange Ratio, rounded down to the nearest whole number of shares of Homology Common Stock, (ii) the per share exercise price for the shares of Homology Common Stock issuable upon exercise of such Assumed Warrant will be equal to the quotient determined by dividing the exercise price per share of Q32 Common Stock at which such Q32 Warrant was exercisable immediately prior to the Effective Time by the Q32 Exchange Ratio, rounded up to the nearest whole cent, and (iii) for terms rendered inoperative by reason of the transactions contemplated by this Agreement (including any anti-dilution or other similar provisions that adjust the number of underlying shares that could become exercisable subject to such Q32 Warrant).

(j) Immediately prior to the Effective Time, the Company shall cause the outstanding principal and accrued but unpaid interest on Q32 Convertible Notes to be converted into the applicable number of shares of Q32 Common Stock provided for under the terms of such Q32 Convertible Note (the “Convertible Notes Conversion”). All of Q32 Convertible Notes converted into shares of Q32 Common Stock shall no longer be outstanding and shall cease to exist, and each holder of Q32 Convertible Notes shall thereafter cease to have any rights with respect to Q32 Convertible Notes. Immediately following the Convertible Notes Conversion, at the Effective Time and by virtue of the Merger, all shares of Q32 Common Stock issued in the Convertible Notes Conversion shall be canceled and converted into the right to receive Homology Common Stock pursuant to this Section 2.4.

2.5 Contingent Value Right.

(a) Prior to the Effective Time, Homology shall declare a distribution (the “Pre-Closing Distribution”) to holders of Homology Common Stock of record the right to receive one contingent value right (each, a “CVR”) for each outstanding share of Homology Common Stock held by such stockholder as of such date, each representing the right to receive contingent payments upon the occurrence of certain events set forth in, and subject to and in accordance with the terms and conditions of, the Contingent Value Rights Agreement in the form attached hereto as Exhibit E, to be entered into between Homology and Equiniti Trust Company, LLC (or such other nationally recognized rights agent agreed to between Homology and Q32) (the “Rights Agent”), with such revisions thereto requested by the Rights Agent that are not, individually or in the aggregate, materially detrimental to the holders of CVRs and reasonably acceptable to Homology and Q32 (the “CVR Agreement”). The record date for the Pre-Closing Distribution shall be the close of business on the last Business Day prior to the day on which the Effective Time occurs and the payment date for the Pre-Closing Distribution shall be three (3) Business Days after the Effective Time; provided that the payment of such distribution may be conditioned upon the occurrence of the Effective Time. In connection with the Pre-Closing Distribution, Homology shall cause the CVR Agreement to be duly authorized, executed and delivered by Homology and the Exchange Agent.

(b) Homology agrees to pay all reasonable costs and fees associated with any action contemplated by this Section 2.5 (the “CVR Fees”).

2.6 Closing of Q32’s Transfer Books. At the Effective Time: (a) all Q32 Common Stock outstanding immediately prior to the Effective Time shall be treated in accordance with Section 2.4(a) and Section 2.4(b), as applicable, and all holders of certificates representing Q32 Common Stock that were outstanding immediately prior to the Effective Time shall cease to have any rights as stockholders of Q32 (other than the right to receive Q32 Merger Shares) and (b) the stock transfer books of Q32 shall be closed with respect to all Q32 Common Stock outstanding immediately prior to the Effective Time. No further transfer of any such Q32 Common Stock shall be made on such stock transfer books after the Effective Time.

2.7 Surrender of Q32 Common Stock.

(a) On or prior to the Closing Date, Homology and Q32 shall jointly select a reputable bank, transfer agent or trust company to act as exchange agent in the Merger (the “Exchange Agent”). At the Effective Time, Homology shall deposit with the Exchange Agent evidence of book-entry shares representing the shares of Homology Common Stock issuable pursuant to Section 2.4(a) in exchange for Q32 Common Stock.

(b) Promptly after the Effective Time, the Parties shall cause the Exchange Agent to mail to the Persons who were record holders of Q32 Common Stock that were converted into the right to receive Q32 Merger Shares: (i) a letter of transmittal in customary form and containing such provisions as Homology may reasonably specify and (ii) instructions for effecting the surrender of Q32 Common Stock in exchange for book-entry shares of Homology Common Stock. Upon surrender of a duly executed letter of transmittal and such other documents as may be reasonably required by the Exchange Agent or Homology, the holder of such Q32 Common Stock shall be entitled to receive in exchange therefor book-entry shares representing Q32 Merger Shares (in a number of whole shares of Homology Common Stock) that such holder has the right to receive pursuant to the provisions of Section 2.4(a).

(c) No dividends or other distributions declared or made with respect to Homology Common Stock with a record date after the Effective Time shall be paid to the holder of any Q32 Common Stock with respect to the shares of Homology Common Stock that such holder has the right to receive in the Merger until such holder delivers a duly executed letter of transmittal (at which time (or, if later, on the applicable payment date) such holder shall be entitled, subject to the effect of applicable abandoned property, escheat or similar Laws, to receive all such dividends and distributions, without interest).

(d) Any shares of Homology Common Stock deposited with the Exchange Agent that remain undistributed to holders of Q32 Common Stock as of the date that is 180 days after the Closing Date shall be delivered to Homology upon demand, and any holders of Q32 Common Stock who have not theretofore delivered a duly executed letter of transmittal in accordance with this Section 2.7 shall thereafter look only to Homology for satisfaction of their claims for Homology Common Stock and any dividends or distributions with respect to shares of Homology Common Stock.

(e) No Party shall be liable to any holder of any Q32 Common Stock or to any other Person with respect to any shares of Homology Common Stock (or dividends or distributions with respect thereto) or for any cash amounts delivered to any public official pursuant to any applicable abandoned property Law, escheat Law or similar Law.

2.8 Calculation of Net Cash.

(a) Not less than ten (10) Business Days prior to the anticipated date for Closing as mutually agreed in good faith by Homology and Q32 (the “Anticipated Closing Date”), Homology will deliver to Q32 a schedule (the “Homology Net Cash Schedule”, and the date of delivery of the Homology Net Cash Schedule, the “Delivery Date”) setting forth, in reasonable detail, Homology’s good faith, estimated calculation of Homology Net Cash (the “Homology Net Cash Calculation”) as of the close of business on the Closing Date (the “Cash Determination Time”) prepared and certified by Homology’s chief financial officer (or if there is no chief

financial officer at such time, the principal financial and accounting officer for Homology). Homology shall make available to Q32 (electronically to the greatest extent possible), as reasonably requested by Q32, the work papers and back-up materials used or useful in preparing the Homology Net Cash Schedule and, if reasonably requested by Q32, Homology’s accountants and counsel at reasonable times and upon reasonable notice. The Homology Net Cash Calculation shall include Homology’s determination, as of the Cash Determination Time, of the defined terms in Section 1.1 necessary to calculate Q32 Merger Shares. Set forth on Section 2.8(a) of the Homology Disclosure Schedule is an illustrative example of Homology Net Cash calculation calculated on a hypothetical basis as of the date described therein.

(b) Within five (5) Business Days after the Delivery Date (the last day of such period, the “Response Date”), Q32 shall have the right to dispute any part of the Homology Net Cash Calculation by delivering a written notice to that effect to Homology (a “Dispute Notice”). Any Dispute Notice shall identify in reasonable detail and to the extent known the nature and amounts of any proposed revisions to the Homology Net Cash Calculation.

(c) If, on or prior to the Response Date, Q32 notifies Homology in writing that it has no objections to the Homology Net Cash Calculation or, if prior to 5:00 p.m. (New York City time) on the Response Date, Q32 has failed to deliver a Dispute Notice as provided in Section 2.8(b), then the Homology Net Cash Calculation as set forth in the Homology Net Cash Schedule shall be deemed to have been finally determined for purposes of this Agreement and to represent the Homology Net Cash at the Cash Determination Time (the “Final Homology Net Cash”) for purposes of this Agreement.

(d) If Q32 delivers a Dispute Notice on or prior to 5:00 p.m. (New York City time) on the Response Date, then Representatives of Homology and Q32 shall promptly, and in no event later than one calendar day after the Response Date, meet and attempt in good faith to resolve the disputed item(s) and negotiate an agreed-upon determination of Homology Net Cash, which agreed upon Homology Net Cash amount shall be deemed to have been finally determined for purposes of this Agreement and to represent the Final Homology Net Cash for purposes of this Agreement.

(e) If Representatives of Homology and Q32 are unable to negotiate an agreed-upon determination of Final Net Cash pursuant to Section 2.8(d) within two (2) calendar days after delivery of the Dispute Notice (or such other period as Homology and Q32 may mutually agree upon), then any remaining disagreements as to the calculation of Homology Net Cash shall be referred to an independent auditor of recognized national standing jointly selected by Homology and Q32 or another independent auditor of recognized national standing mutually agreed upon by Homology and Q32 (the “Accounting Firm”). Homology shall promptly deliver to the Accounting Firm all work papers and back-up materials used in preparing the Homology Net Cash Schedule, and Homology and Q32 shall use commercially reasonable efforts to cause the Accounting Firm to make its determination within five (5) calendar days of accepting its selection. Homology and Q32 shall be afforded the opportunity to present to the Accounting Firm any material related to the unresolved disputes and to discuss the issues with the Accounting Firm; provided, however, that no such presentation or discussion shall occur without the presence of a Representative of each of Homology and Q32. The determination of the Accounting Firm shall be limited to the disagreements submitted to the Accounting Firm. The determination of the amount of Homology Net Cash made by the Accounting Firm shall be made in writing delivered to each of Homology and Q32, shall be final and binding on Homology and Q32 and shall be deemed to have been finally determined for purposes of this Agreement and to represent the Final Homology Net Cash for purposes of this Agreement. The Parties shall delay the Closing until the resolution of the matters described in this Section 2.8(e). The fees and expenses of the Accounting Firm shall be allocated between Homology and Q32 in the same proportion that the disputed amount of the Homology Net Cash that was unsuccessfully disputed by such Party (as finally determined by the Accounting Firm) bears to the total disputed amount of the Homology Net Cash amount and such portion of the costs and expenses of the Accounting Firm borne by Q32 and any other fees, costs or expenses incurred by Q32 following the Anticipated Closing Date in connection with the procedures set forth in this Section 2.8(e) shall be deducted from the final determination of the amount of Homology Net Cash. If this

Section 2.8(e) applies as to the determination of the Final Homology Net Cash described in Section 2.8(a), upon resolution of the matter in accordance with this Section 2.8(e), the Parties shall not be required to determine Homology Net Cash again even though the Closing Date may occur later than the Anticipated Closing Date, except that either Homology and Q32 may require a redetermination of the Final Homology Net Cash if the Closing Date is more than ten (10) calendar days after the Anticipated Closing Date.

2.9 Further Action. If, at any time after the Effective Time, any further action is determined by the Surviving Corporation to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of Q32, then the officers and manager of the Surviving Corporation shall be fully authorized, and shall use their and its commercially reasonable efforts (in the name of Q32, in the name of Merger Sub, in the name of the Surviving Corporation and otherwise) to take such action.

2.10 Withholding. Each of the Exchange Agent, Homology and the Surviving Corporation (each, a “Withholding Agent”) shall be entitled to deduct and withhold from any consideration deliverable pursuant to this Agreement (including the Pre-Closing Distribution) such amounts as are required to be deducted or withheld from such consideration under the Code or under any other applicable Law; provided, however, that if a Withholding Agent determines that any payment in connection with the Contemplated Transactions is subject to deduction and/or withholding, then, except with respect to compensatory payments or as a result of a failure to deliver the certificate described in Section 5.16(b), such Withholding Agent shall use commercially reasonable efforts to (i) provide reasonable advance notice to such recipient of any required deduction or withholding and (ii) reasonably cooperate with such recipient to reduce or eliminate any such deduction and/or withholding. To the extent such amounts are so deducted or withheld, such amounts shall be (i) timely remitted to the appropriate Governmental Authority and (ii) treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF Q32

Except as set forth in the written disclosure schedule delivered by Q32 to Homology (the “Q32 Disclosure Schedule”), Q32 represents and warrants to Homology and Merger Sub as follows:

3.1 Due Organization; Subsidiaries.

(a) Q32 is a corporation or other legal entity duly incorporated or otherwise organized, validly existing and in good standing under the Laws of the jurisdiction of its incorporation or organization and has all necessary power and authority: (i) to conduct its business in the manner in which its business is currently being conducted, (ii) to own or lease and use its property and assets in the manner in which its property and assets are currently owned or leased and used and (iii) to perform its obligations under all Contracts by which it is bound.

(b) Each of Q32 and its Subsidiaries is licensed and qualified to do business, and is in good standing (to the extent applicable in such jurisdiction), under the Laws of all jurisdictions where the nature of its business in the manner in which its business is currently being conducted requires such licensing or qualification other than in jurisdictions where the failure to be so qualified individually or in the aggregate would not be reasonably expected to have a Q32 Material Adverse Effect.

(c) Except as set forth on Section 3.1(c) of the Q32 Disclosure Schedule, Q32 has no Subsidiaries and Q32 does not directly or indirectly own any capital stock of, or any equity ownership or profit sharing interest of any nature in, or control directly or indirectly, any other Entity. Q32 is not and has not otherwise been, directly or indirectly, a party to, member of or participant in any partnership, joint venture or similar business entity. Q32

has not agreed and is not obligated to make, or is bound by any Contract under which it may become obligated to make, any future investment in or capital contribution to any other Entity. Q32 has not, at any time, been a general partner of, and has not otherwise been liable for any of the debts or other obligations of, any general partnership, limited partnership or other Entity.

3.2 Organizational Documents. Q32 has delivered to Homology accurate and complete copies of Q32’s Organizational Documents. Q32 is not in breach or violation of its Organizational Documents in any material respect.

3.3 Authority; Binding Nature of Agreement. Q32 has all necessary corporate power and authority to enter into and to perform its obligations under this Agreement and to consummate the Contemplated Transactions. The Q32 Board (at meetings duly called and held) has (i) determined that the Contemplated Transactions are fair to, advisable and in the best interests of Q32 and its stockholders, (ii) approved and declared advisable this Agreement and the Contemplated Transactions and (iii) determined to recommend the Q32 Board Recommendation to the stockholders of Q32. This Agreement has been duly executed and delivered by Q32 and assuming the due authorization, execution and delivery by Homology and Merger Sub, constitutes the legal, valid and binding obligation of Q32, enforceable against Q32 in accordance with its terms, subject to the Enforceability Exceptions.

3.4 Vote Required. The affirmative vote of the holders of at least (i) a majority of the then outstanding shares of Q32 Common Stock outstanding on the record date for the Q32 Stockholder Written Consent and (ii) a majority of the then outstanding shares of Q32 Preferred Stock voting as a single class on an as-converted basis (together, the “Required Q32 Stockholder Vote”), is the only vote of the holders of any class or series of Q32 Capital Stock necessary to adopt and approve this Agreement and approve the Contemplated Transactions. No interest in Q32 is subject to any appraisal or dissenters rights in connection with the Contemplated Transactions.

3.5 Non-Contravention; Consents.

(a) Subject to obtaining the Required Q32 Stockholder Vote and the filing of the Certificate of Merger required by Delaware Law, neither (x) the execution, delivery or performance of this Agreement by Q32, nor (y) the consummation of the Contemplated Transactions, will directly or indirectly (with or without notice or lapse of time):

(i) contravene, conflict with or result in a violation of any of the provisions of the Organizational Documents of Q32 or its Subsidiaries;

(ii) contravene, conflict with or result in a material violation of, or give any Governmental Authority or other Person the right to challenge the Contemplated Transactions or to exercise any remedy or obtain any relief under, any Law or any Order to which Q32 or its Subsidiaries, or any of the assets owned or used by Q32 or its Subsidiaries, is subject;

(iii) contravene, conflict with or result in a material violation of any of the terms or requirements of, or give any Governmental Authority the right to revoke, withdraw, suspend, cancel, terminate or modify, any Governmental Authorization that is held by Q32 or its Subsidiaries or that otherwise relates to the business of Q32, or any of the assets owned, leased or used by Q32;

(iv) contravene, conflict with or result in a violation or breach of, or result in a default under, any provision of any Q32 Material Contract, or give any Person the right to: (A) declare a default or exercise any remedy under any Q32 Material Contract, (B) any material payment, rebate, chargeback, penalty or change in delivery schedule under any such Q32 Material Contract, (C) accelerate the maturity or performance of any Q32 Material Contract or (D) cancel, terminate or modify any term of any Q32 Material Contract, except in the case of any nonmaterial breach, default, penalty or modification; or

(v) result in the imposition or creation of any Encumbrance upon or with respect to any asset owned or used by Q32 or its Subsidiaries (except for Permitted Encumbrances).

(b) Except for (i) any Consent set forth on Section 3.5 of the Q32 Disclosure Schedule under any Q32 Contract, (ii) the Required Q32 Stockholder Vote, (iii) the filing of the Certificate of Merger with the Secretary of State of the State of Delaware pursuant to Delaware Law and (iv) such consents, waivers, approvals, orders, authorizations, registrations, declarations and filings as may be required under applicable federal and state securities laws, neither Q32 nor any of its Subsidiaries was, is or will be required to make any filing with or give any notice to, or to obtain any Consent from, any Person in connection with (x) the execution, delivery or performance of this Agreement or (y) the consummation of the Contemplated Transactions.

(c) The Q32 Board has taken and will take all actions necessary to ensure that the restrictions applicable to business combinations contained in Section 203 of Delaware Law are, and will be, inapplicable to the execution, delivery and performance of this Agreement and to the consummation of the Contemplated Transactions. No other state takeover statute or similar Law applies or purports to apply to the Merger, this Agreement or any of the other Contemplated Transactions.

3.6 Capitalization.

(a) The authorized capital stock of Q32 consists of (i) 141,900,000 shares of Q32 Common Stock of which 7,274,482 shares have been issued and are outstanding as of November 12, 2023 , and (ii) 117,933,356 shares of Q32 Preferred Stock of which (a) 6,500,000 shares have been designated Q32 Series A1 Preferred Stock of which 6,500,000 shares have been issued and are outstanding as of November 12, 2023, (b) 47,628,788 shares have been designated Q32 Series A Preferred Stock of which 47,628,788 shares have been issued and are outstanding as of November 12, 2023 and (d) 63,804,568 shares have been designated Q32 Series B Preferred Stock of which 54,689,627 shares have been issued and are outstanding as of November 12, 2023.

agreement evidencing a Q32 Option that does not conform in all material respects to the standard form agreement.

(d) Except as set forth on Section 3.6(c) of the Q32 Disclosure Schedule, there is no: (i) outstanding subscription, option, call, warrant or right (whether or not currently exercisable) to acquire any shares of the capital stock or other securities of Q32, (ii) outstanding security, instrument or obligation that is or may become convertible into or exchangeable for any shares of the capital stock or other securities of Q32, (iii) stockholder rights plan (or similar plan commonly referred to as a “poison pill”) or Contract under which Q32 is or may become obligated to sell or otherwise issue any shares of its capital stock or any other securities or (iv) condition or circumstance that may give rise to or provide a basis for the assertion of a claim by any Person to the effect that such Person is entitled to acquire or receive any shares of capital stock or other securities of Q32.

(b) The Q32 Financial Statements (i) were prepared in accordance with GAAP (except the Q32 Interim Financial Statements and are subject to normal and recurring year-end adjustments that are not reasonably expected to be material in amount) applied on a consistent basis unless otherwise noted therein throughout the periods indicated, (ii) fairly present, in all material respects, the financial position of Q32 as of the respective dates thereof and the results of operations and cash flows of Q32 for the periods covered thereby and (iii) when delivered by Q32 for inclusion in the Registration Statement (as defined below) for filing with the SEC following the date of this Agreement in accordance with Section 5.7, shall comply in all material respects with the applicable accounting requirements and with the rules and regulations of the SEC, the Exchange Act and the Securities Act applicable to a registrant, in effect as of the respective dates thereof.

5.3 Access and Investigation.

(a) Subject to the terms of the Confidentiality Agreement, which the Parties agree will continue in full force following the date of this Agreement, during the Pre-Closing Period, upon reasonable notice, Homology, on the one hand, and Q32, on the other hand, shall and shall use commercially reasonable efforts to cause such Party’s Representatives to: (i) provide the other Party and such other Party’s Representatives with reasonable access during normal business hours to such Party’s Representatives, personnel and assets and to all existing books, records, Tax Returns, work papers and other documents and information relating to such Party and its Subsidiaries, (ii) provide the other Party and such other Party’s Representatives with such copies of the existing books, records, Tax Returns, work papers, product data, and other documents and information relating to such Party and its Subsidiaries, and with such additional financial, operating and other data and information regarding such Party and its Subsidiaries as the other Party may reasonably request, (iii) permit the other Party’s officers and other employees to meet, upon reasonable notice and during normal business hours, with the chief financial officer and other officers and managers of such Party responsible for such Party’s financial statements and the internal controls of such Party to discuss such matters as the other Party may deem reasonably necessary or appropriate, and (iv) provide the other Party with copies, when available, of unaudited financial statements or management accounts, and communications sent by or on behalf of such Party to its stockholders or any material notice, report or other document filed with or sent to or received from any Governmental Authority in connection with the Contemplated Transactions. Any investigation conducted by either Homology or Q32 pursuant to this Section 5.3 shall be conducted in such manner as not to interfere unreasonably with the conduct of the business of the other Party.

(b) Notwithstanding anything herein to the contrary in this Section 5.3, no access or examination contemplated by this Section 5.3 shall be permitted to the extent that it would require any Party or its Subsidiaries to waive the attorney-client privilege or attorney work product privilege, or violate any applicable Law; provided, that such Party or its Subsidiary (i) shall be entitled to withhold only such information that may not be provided without causing such violation or waiver, (ii) shall provide to the other Party all related information that may be provided without causing such violation or waiver (including, to the extent permitted, redacted versions of any such information) and (iii) shall enter into such effective and appropriate joint-defense agreements or other protective arrangements as may be reasonably requested by the other Party in order that all such information may be provided to the other Party without causing such violation or waiver.

5.4 No Solicitation.

(a) Each of Homology and Q32 agrees that, during the Pre-Closing Period, neither it nor any of its Subsidiaries shall, nor shall it or any of its Subsidiaries authorize any of its Representatives to, directly or indirectly: (i) solicit, initiate or knowingly encourage, induce or facilitate the communication, making, submission or announcement of any Acquisition Proposal or Acquisition Inquiry or take any action otherwise inconsistent with past practice that could reasonably be expected to lead to an Acquisition Proposal or Acquisition Inquiry, (ii) furnish any non-public information regarding such Party to any Person (other than Q32 or Homology) in connection with or in response to an Acquisition Proposal or Acquisition Inquiry, (iii) engage in discussions or negotiations with any Person with respect to any Acquisition Proposal or Acquisition Inquiry, (iv) approve, endorse or recommend any Acquisition Proposal (subject to Section 5.9), (v) execute or enter into any letter of intent or any Contract contemplating or otherwise relating to any Acquisition Transaction or (vi) publicly propose to do any of the foregoing; provided, however, that, notwithstanding anything contained in this Section 5.3(a) and subject to compliance with this Section 5.3(a), prior to the approval of this Agreement by Homology’s stockholders (i.e., the Required Homology Stockholder Vote), Homology may furnish non-public information regarding Homology and its Subsidiaries to, and enter into discussions or negotiations with, any Person in response to a bona fide written Acquisition Proposal by Homology which the Homology Board determines in good faith, after consultation with Homology’s financial advisors and outside legal counsel, constitutes, or is reasonably likely to result in, a Superior Offer (and is not withdrawn) if: (A) neither Homology nor any Representative of Homology shall have breached this Section 5.3(a) in any material respect, (B) the Homology Board concludes in good faith based on the advice of outside legal counsel, that the failure to take such action would reasonably be expected to be inconsistent with the fiduciary duties of the Homology Board under applicable Law, (C) as promptly as possible after (and in any event within forty-eight hours of) initially furnishing any such non-public information to, or entering into discussions with, such Person, Homology gives Q32 written notice of the identity of such Person to Q32, and of Homology’s intention to furnish non-public information to, or enter into discussions with, such Person, (D) Homology receives from such Person an executed Acceptable Confidentiality Agreement and (E) as promptly as possible after (and in any event within forty-eight hours of) furnishing any such non-public information to such Person, Homology furnishes such non-public information to Q32 (to the extent such information has not been previously furnished by Homology to Q32). Notwithstanding anything to the contrary set forth in this Agreement, Homology and its Representatives may, in any event (without the Homology Board having to make a determination in clause (B) of the preceding sentence), contact any person to (i) seek to clarify and understand the terms and conditions of any Acquisition Proposal made by such Person solely to determine whether such Acquisition Proposal constitutes, or is reasonably likely to result in, a Superior Offer and (ii) inform such Person that has made or, to the knowledge of Homology is considering making an Acquisition Proposal. Without limiting the generality of the foregoing, Homology acknowledges and agrees that, in the event any Representative of Homology takes any action that, if taken by Homology, would constitute a breach of this Section 5.3(a) by Homology, the taking of such action by such Representative shall be deemed to constitute a breach of this Section 5.3(a) by Homology for purposes of this Agreement.

(b) If any Party or any Representative of such Party receives an Acquisition Proposal or Acquisition Inquiry at any time during the Pre-Closing Period, then such Party shall promptly (and in no event later than one

Business Day after such Party becomes aware of such Acquisition Proposal or Acquisition Inquiry) advise the other Party orally and in writing of such Acquisition Proposal or Acquisition Inquiry (including the identity of the Person making or submitting such Acquisition Proposal or Acquisition Inquiry, and provide a copy of the Acquisition Proposal or Acquisition Inquiry, of if the Acquisition Proposal or Acquisition Inquiry is not written, the terms thereof). Such Party shall keep the other Party reasonably informed with respect to the status and terms of any such Acquisition Proposal or Acquisition Inquiry and any material modification or material proposed modification thereto. In addition to the foregoing, each Party shall provide the other Party with at least forty-eight hours written notice of a meeting of its board of directors (or any committee thereof) at which its board of directors (or any committee thereof) is reasonably expected to consider an Acquisition Proposal or Acquisition Inquiry it has received.

(c) Each Party shall immediately cease and cause to be terminated any existing discussions, negotiations and communications with any Person that relate to any Acquisition Proposal or Acquisition Inquiry as of the date of this Agreement and request the destruction or return of any non-public information provided to such Person.

5.5 Notification of Certain Matters.

(a) During the Pre-Closing Period, each of Q32, on the one hand, and Homology, on the other hand, shall promptly notify the other (and, if in writing, furnish copies of) if any of the following occurs: (i) any notice or other communication is received from any Person alleging that the Consent of such Person is or may be required in connection with any of the Contemplated Transactions, (ii) any Legal Proceeding against or involving or otherwise affecting such Party or its Subsidiaries is commenced, or, to the Knowledge of such Party, threatened against such Party or, to the Knowledge of such Party, any director, officer or Key Employee of such Party, (iii) such Party becomes aware of any inaccuracy in any representation or warranty made by such Party in this Agreement or (iv) the failure of such Party to comply with any covenant or obligation of such Party; in each case that could reasonably be expected to make the timely satisfaction of any of the conditions set forth in Article VI impossible or materially less likely. No such notice shall be deemed to supplement or amend the Q32 Disclosure Schedule or the Homology Disclosure Schedule for the purpose of (A) determining the accuracy of any of the representations and warranties made by Q32 or Homology in this Agreement or (B) determining whether any condition set forth in Article VI has been satisfied. Any failure by either Party to provide notice pursuant to this Section 5.5 shall not be deemed to be a breach for purposes of Section 6.2(b) or 6.3(b), as applicable, unless such failure to provide such notice was knowing and intentional.

(b) During the Pre-Closing Period, Homology shall use reasonable best efforts to consult with Q32 during the negotiation process for, and prior to taking any material action with respect to, any amendment to, sublicense or the potential early termination of the Homology Lease, and shall consider any input received from Q32 in good faith prior to taking any such action.

(c) During the Pre-Closing Period, Homology shall provide to Q32 an updated list of Abandoned Homology Legacy IP Rights on a monthly basis starting from December 1, 2023, with the final such list to be delivered within three (3) days preceding Closing.

5.6 Legacy Asset Disposition.

(a) Prior to the Closing Date, Homology shall be entitled, but under no obligation, to sell, transfer, license, assign or otherwise divest any or all of the assets and rights primarily relating to Homology’s HMI-103 (Adult/Pediatric PKU), HMI-203 (MPS II (Hunter Syndrome)), HMI-204 (MLD), Capsids and AAVHSC Platform (the “Legacy Assets”), including any equity interests held directly or indirectly by Homology in Oxford Biomedica Solutions, LLC or its affiliates (the “Oxford Assets”) in a transaction or series of transactions (the “Legacy Asset Disposition”), provided that Homology as promptly as practicable thereafter notify Q32 of any such Legacy Asset Disposition. Each Party acknowledges that Homology may, in contemplation of the Legacy Asset Disposition, (a) establish one or more Subsidiaries to hold the Legacy Assets, (b) transfer to any such Subsidiary

any or all of the Legacy Assets and the liabilities and obligations related thereto and (c) take such other steps that are reasonably necessary to prepare for the Legacy Asset Disposition. For clarity, if Homology transfers the Legacy Assets to one or more Subsidiaries, the terms of this Section 0 shall apply to such Subsidiaries in addition to Homology. Each Party further acknowledges that Homology may not be successful in completing, or may determine not to proceed, with the Legacy Asset Disposition. Notwithstanding the foregoing, Homology may not enter into any agreement with respect to the Legacy Asset Disposition that would result in a continuing obligation or liability without the prior written consent of Q32 (such consent shall not be unreasonably withheld, conditioned or delayed); provided, further, that Homology shall provide Q32 with a copy of any agreement with respect to an Legacy Asset Disposition that would be reasonably likely to result in a continuing obligation or liability of either Homology or Q32 on or after the Effective Time at least five Business Days prior to entry into such agreement.

(b) For the avoidance of doubt, any sale, transfer, license, assignment or other divestiture of Legacy Assets on or after the Closing Date shall be governed by the terms and conditions of the CVR Agreement.

5.7 Registration Statement; Proxy Statement.

(a) As promptly as practicable (but in any event, no later than twenty (20) Business Days) after the date of this Agreement, (i) Homology, in cooperation with Q32, shall prepare and file with the SEC a proxy statement relating to the Homology Stockholder Meeting to be held in connection with the Merger (together with any amendments thereof or supplements thereto, the “Proxy Statement”) and (ii) Homology, in cooperation with Q32, shall prepare and file with the SEC a registration statement on Form S-4 (the “Form S-4”), in which the Proxy Statement shall be included as a part (the Proxy Statement and the Form S-4, collectively, the “Registration Statement”), in connection with the registration under the Securities Act of the shares of Homology Common Stock to be issued by virtue of the Merger. Each of Homology and Q32 shall use their commercially reasonable efforts to respond promptly to any comments of the SEC or its staff and to cause the Registration Statement to become effective as promptly as practicable, and shall take all or any action required under any applicable federal, state, securities and other Laws in connection with the issuance of shares of Homology Common Stock pursuant to the Merger. Each of the Parties shall furnish all information concerning itself and their Affiliates, as applicable, to the other Parties as the other Parties may reasonably request in connection with such actions and the preparation of the Registration Statement and Proxy Statement.

(b) Homology covenants and agrees that the Registration Statement (and the letter to stockholders, notice of meeting and form of proxy included therewith) will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements made therein not misleading. Q32 covenants and agrees that the information supplied by or on behalf of Q32 and its Subsidiaries to Homology for inclusion in the Registration Statement (including the Q32 Financials) will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make such information, in light of the circumstances under which they were made, not misleading. Notwithstanding the foregoing, Homology makes no covenant, representation or warranty with respect to statements made in the Registration Statement (and the letter to stockholders, notice of meeting and form of proxy included therewith), if any, based on information provided by Q32 or its Subsidiaries or any of their Representatives for inclusion therein. Q32 and its legal counsel shall be given reasonable opportunity to review and comment on the Registration Statement, including all amendments and supplements thereto, prior to the filing thereof with the SEC, and on the response to any comments on the SEC prior to the filing thereof with the SEC; provided, however, that the foregoing shall not apply to any amendment to the Registration Statement pertaining to a Homology Board Adverse Recommendation Change. Each of the Parties shall use commercially reasonable efforts to cause the Registration Statement to comply with the applicable rules and regulations promulgated by the SEC, to respond promptly to any comments of the SEC or its staff and to have the Registration Statement declared effective under the Securities Act as promptly as practicable after it is filed with the SEC.

(c) Each of the Parties shall use commercially reasonable efforts to cause the Proxy Statement to be mailed to Homology’s stockholders as promptly as practicable after the Registration Statement is declared effective under the Securities Act. If Homology, Merger Sub or Q32 become aware of any event or information that, pursuant to the Securities Act or the Exchange Act, should be disclosed in an amendment or supplement to the Registration Statement or Proxy Statement, as the case may be, then such Party, as the case may be, shall promptly inform the other Parties thereof and shall cooperate with such other Parties in filing such amendment or supplement with the SEC and, if appropriate, in mailing such amendment or supplement to the Homology stockholders.

(d) Q32 shall reasonably cooperate with Homology and provide, and cause its Representatives to provide, Homology and its Representatives, with all true, correct and complete information regarding (i) Q32 and its Subsidiaries and (ii) the 2023 Plans that is, in each case, required by Law to be included in the Registration Statement or reasonably requested by Homology to be included in the Registration Statement. Q32 will use commercially reasonable efforts to cause Q32’s independent accounting firm to deliver any consent that Homology is required to file with the SEC with respect to the inclusion of the independent accounting firm’s opinion on the audited financial statements of Q32 in any filing of the Registration Statement with the SEC.

(e) As promptly as practicable following the date of this Agreement and no later than fifteen (15) Business Days after the date of this Agreement, Q32 shall deliver to Homology financial statements (including any related notes thereto) of Q32 and its consolidated Subsidiaries as of and for the fiscal years ended December 31, 2022 and 2021, with respect to which the PCAOB Auditor has substantially completed its audit work in accordance with the standards of the PCAOB, subject to providing the PCAOB Auditor’s report thereon for inclusion in the Registration Statement. As promptly as practicable following the date of this Agreement and no later than fifteen (15) Business Days after the date of this Agreement, Q32 shall deliver to Homology unaudited interim financial statements (including any related notes thereto) of Q32 and its consolidated Subsidiaries as of and for the nine months ended September 30, 2023 and 2022, with respect to which the PCAOB Auditor has substantially completed its review in accordance with the procedures specified by the PCAOB in AS 4105, Reviews of Interim Financial Information (the “interim review procedures”), for inclusion in the Registration Statement. All such financial statements included in the Registration Statement at the time of filing shall comply as to form in all material respects, shall be prepared in accordance with GAAP (as modified by the rules and regulations of the SEC) applied on a consistent basis throughout the periods involved, shall fairly present in all material respects the consolidated financial position at the date thereof and the results of its operations and cash flows as of and for the periods therein indicated and shall comply in all material respects with the applicable accounting requirements and with the rules and regulations of the SEC, the Exchange Act and the Securities Act applicable to a registrant, in effect as of the respective dates thereof.

5.8 Q32 Stockholder Written Consent.

(a) Promptly after the Registration Statement has been declared effective under the Securities Act, and in any event no later than two (2) Business Days thereafter, Q32 shall prepare, with the cooperation of Homology, and cause to be mailed to its stockholders an information statement, which shall include a copy of the Proxy Statement (the “Information Statement”), and the Q32 Stockholder Written Consent, in order to solicit the approval of Q32’s stockholders, including but not limited to Q32’s stockholders sufficient for the Required Q32 Stockholder Vote in lieu of a meeting pursuant to Section 228 of Delaware Law, for purposes of (i) adopting and approving this Agreement and the Contemplated Transactions, and (ii) acknowledging that the approval given thereby is irrevocable. Q32 shall use its reasonable best efforts to cause Q32’s stockholders sufficient for the Required Q32 Stockholder Vote to execute and deliver to Q32 the Q32 Stockholder Written Consent promptly following delivery thereof, and in any event no later than fifteen (15) days after the Registration Statement has been declared effective. Promptly following receipt of the duly executed Q32 Stockholder Written Consent, Q32 shall deliver a copy of the duly executed Q32 Stockholder Written Consent to Homology. Under no circumstances shall Q32 assert that any other approval or consent is necessary by its stockholders to approve this Agreement and the Contemplated Transactions.

(b) Promptly following receipt of the Required Q32 Stockholder Vote, Q32 shall prepare and mail a notice to every stockholder of Q32 that did not execute the Q32 Stockholder Written Consent. Such notice shall (i) be a statement to the effect that the Q32 Board determined that the Merger is advisable in accordance with Section 251(b) of Delaware Law and in the best interests of the stockholders of Q32 and approved and adopted this Agreement, the Merger and the other Contemplated Transactions, and (ii) provide the stockholders of Q32 to whom it is sent with notice of the actions taken in the Q32 Stockholder Written Consent, including the adoption and approval of this Agreement, the Merger and the other Contemplated Transactions in accordance with Section 228(e) of Delaware Law and Q32’s Organizational Documents.

(c) Q32 agrees that: (i) the Q32 Board shall recommend that Q32’s stockholders vote to adopt and approve this Agreement and the Contemplated Transactions and shall use commercially reasonable efforts to solicit such approval within the time set forth in Section 5.8(a) (the recommendation of the Q32 Board that Q32’s stockholders vote to adopt and approve this Agreement being referred to as the “Q32 Board Recommendation”) and (ii) the Q32 Board Recommendation shall not be withdrawn or modified (and the Q32 Board shall not publicly propose to withdraw or modify the Q32 Board Recommendation) in a manner adverse to Homology, and no resolution by the Q32 Board or any committee thereof to withdraw or modify the Q32 Board Recommendation in a manner adverse to Homology or to adopt, approve or recommend (or publicly propose to adopt, approve or recommend) any Acquisition Proposal shall be adopted or proposed.

(d) Q32’s obligation to solicit the consent of its stockholders to sign the Q32 Stockholder Written Consent in accordance with Section 5.8(a) shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission of any Superior Offer or other Acquisition Proposal.

5.9 Homology Stockholder Meeting.

(a) Homology shall take all action necessary under applicable Law to call, give notice of and hold a meeting of the holders of Homology Common Stock to consider and vote to approve this Agreement and the Contemplated Transactions, including the issuance of the shares of Homology Common Stock to the stockholders of Q32 pursuant to the terms of this Agreement and the Charter Amendment Proposal (collectively, the “Homology Stockholder Matters” and such meeting, the “Homology Stockholder Meeting”). The Homology Stockholder Meeting shall be held as promptly as practicable after the Registration Statement is declared effective under the Securities Act, and in any event no later than forty-five (45) days after the effective date of the Registration Statement. Homology shall take reasonable measures to ensure that all proxies solicited in connection with the Homology Stockholder Meeting are solicited in compliance with all applicable Law. Notwithstanding anything to the contrary contained herein, if on the date of the Homology Stockholder Meeting, or a date preceding the date on which the Homology Stockholder Meeting is scheduled, Homology reasonably believes that (i) it will not receive proxies sufficient to obtain the Required Homology Stockholder Vote, whether or not a quorum would be present or (ii) it will not have sufficient shares of Homology Common Stock represented (whether in person or by proxy) to constitute a quorum necessary to conduct the business of the Homology Stockholder Meeting, Homology may postpone or adjourn, or make one or more successive postponements or adjournments of, the Homology Stockholder Meeting as long as the date of the Homology Stockholder Meeting is not postponed or adjourned more than an aggregate of thirty (30) calendar days in connection with any postponements or adjournments.

(b) Homology agrees that, subject to Section 5.9(c): (i) the Homology Board shall recommend that the holders of Homology Common Stock vote to approve the Homology Stockholder Matters and shall use commercially reasonable efforts to solicit such approval within the timeframe set forth in Section 5.9(a) above, (ii) the Proxy Statement shall include a statement to the effect that the Homology Board recommends that Homology’s stockholders vote to approve the Homology Stockholder Matters (the recommendation of the Homology Board being referred to as the “Homology Board Recommendation”) and (iii) the Homology Board Recommendation shall not be withheld, amended, withdrawn or modified (and the Homology Board shall not publicly propose to withhold, amend, withdraw or modify the Homology Board Recommendation) in a manner

adverse to Q32, and no resolution by the Homology Board or any committee thereof to withdraw or modify the Homology Board Recommendation in a manner adverse to Q32 or to adopt, approve or recommend (or publicly propose to adopt, approve or recommend) any Acquisition Proposal shall be adopted or proposed (the actions set forth in the foregoing clause (iii), collectively, a “Homology Board Adverse Recommendation Change”).

(c) Notwithstanding anything to the contrary contained in Section 5.9(b), and subject to compliance with Section 5.4 and Section 5.9, at any time prior to the approval of Homology Stockholder Matters by the Required Homology Stockholder Vote, Homology receives a bona fide written Superior Offer, the Homology Board may make a Homology Board Adverse Recommendation Change if, but only if, in the receipt of and on account of such Superior Offer, (i) the Homology Board determines in good faith, after consultation with its outside legal counsel, that the failure to make a Homology Board Adverse Recommendation Change would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law, (ii) Homology has, and has caused its financial advisors and outside legal counsel to, during the Notice Period, negotiate with Q32 in good faith to make such adjustments to the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Offer and (iii) if after Q32 shall have delivered to Homology a written offer to alter the terms or conditions of this Agreement during the Notice Period (or if Q32 declines to do so), the Homology Board shall have determined in good faith, after consultation with its outside legal counsel, that the failure to withhold, amend, withdraw or modify the Homology Board Recommendation would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law (after taking into account such alterations of the terms and conditions of this Agreement, if any); provided that (x) Q32 receives written notice from Homology confirming that the Homology Board has determined to change its recommendation during the Notice Period, which notice shall include a description in reasonable detail of the reasons for such Homology Board Adverse Recommendation Change, and written copies of any relevant proposed transaction agreements with any party making a potential Superior Offer, (y) during any Notice Period, Q32 shall be entitled to deliver to Homology one or more counterproposals to such Acquisition Proposal and Homology will, and cause its Representatives to, negotiate with Q32 in good faith (to the extent Q32 desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that the applicable Acquisition Proposal ceases to constitute a Superior Offer and (z) in the event of any material amendment to any Superior Offer (including any revision in price or percentage of the combined company that Homology’s stockholders would receive as a result of such potential Superior Offer), Homology shall be required to provide Q32 with notice of such material amendment and the Notice Period shall be extended, if applicable, to ensure that at least two (2) Business Days remain in the Notice Period following such notification during which the parties shall comply again with the requirements of this Section 5.9(c) and the Homology Board shall not make a Homology Board Adverse Recommendation Change prior to the end of such Notice Period as so extended (it being understood that there may be multiple extensions).

(d) Homology’s obligation to call, give notice of and hold the Homology Stockholder Meeting in accordance with Section 5.9(a) shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission of any Superior Offer or Acquisition Proposal, or by any withdrawal or modification of the Homology Board Recommendation.

(e) Nothing contained in this Agreement shall prohibit Homology or the Homology Board from complying with Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act; provided, however, that any disclosure made by Homology or the Homology Board pursuant to Rules 14d-9 and 14e-2(a) shall be limited to a statement that Homology is unable to take a position with respect to the bidder’s tender offer unless the Homology Board determines in good faith, after consultation with its outside legal counsel, that such statement would result in a breach of its fiduciary duties under applicable Law.

5.10 Efforts; Regulatory Approvals.

(a) The Parties shall use commercially reasonable efforts to consummate the Contemplated Transactions. Without limiting the generality of the foregoing, each Party: (i) shall make all filings and other submissions (if any) and give all notices (if any) required to be made and given by such Party in connection with the

Contemplated Transactions, (ii) shall use commercially reasonable efforts to obtain each Consent (if any) reasonably required to be obtained (pursuant to any applicable Law or Contract, or otherwise) by such Party in connection with the Contemplated Transactions or for such Contract to remain in full force and effect, (iii) shall use commercially reasonable efforts to lift any injunction prohibiting, or any other legal bar to, the Contemplated Transactions and (iv) shall use commercially reasonable efforts to satisfy the conditions precedent to the consummation of this Agreement.

5.11 Disclosures. Without limiting any Party’s obligations under the Confidentiality Agreement, no Party shall, and no Party shall permit any of its Subsidiaries or any of its Representative to, issue any press release or make any disclosure (to any customers or employees of such Party, to the public or otherwise) regarding the Contemplated Transactions unless: (a) the other Party shall have approved such press release or disclosure in writing, such approval not to be unreasonably conditioned, withheld or delayed; or (b) such Party shall have determined in good faith, upon the advice of outside legal counsel, that such disclosure is required by applicable Law and, to the extent practicable, before such press release or disclosure is issued or made, such Party advises the other Party of, and consults with the other Party regarding, the text of such press release or disclosure; provided, however, that each of Q32 and Homology may make any statement in response to questions by the press, analysts, investors or those attending industry conferences or financial analyst conference calls, so long as any such statements are consistent with previous press releases, public disclosures or public statements made by Q32 and Homology in compliance with this Section 5.11. Notwithstanding the foregoing, a Party need not consult with any other Parties in connection with such portion of any press release, public statement or filing to be issued or made pursuant to Section 5.9(d) or with an Acquisition Proposal, or Homology Board Adverse Recommendation Change with respect to Homology only pursuant to Section 5.9(e).

5.12 Homology Options. Prior to the Closing, the Homology Board shall have adopted appropriate resolutions and taken all other actions necessary and appropriate to provide (a) each outstanding Homology Option that is not a Homology ITM Option will be cancelled for no consideration and (b) that the vesting and exercisability of each unexpired, unexercised and unvested Homology ITM Option shall be accelerated in full, in each case, effective as of immediately prior to the Effective Time, contingent on the occurrence of the Closing.

5.13 Homology Restricted Stock Unit Awards. Prior to the Closing, the Homology Board shall have adopted appropriate resolutions and taken all other actions necessary and appropriate to provide that (a) the vesting of each outstanding and unvested Homology Restricted Stock Unit Award shall be accelerated in full effective as of immediately prior to the Effective Time, contingent on the occurrence of the Closing and (b) for each outstanding and unsettled Homology Restricted Stock Unit Award, the holder thereof shall receive, immediately prior to the Effective Time, a number of shares of Homology Common Stock equal to the number of vested and unsettled shares of Homology Common Stock underlying such Homology Restricted Stock Unit Award. Notwithstanding anything herein to the contrary, the Tax withholding obligations for each holder receiving shares of Homology Common Stock in accordance with the preceding sentence shall be satisfied by Homology withholding from issuance that number of shares of Homology Common Stock calculated by multiplying the maximum statutory withholding rate for such holder in connection with such issuance by the number of shares of Homology Common Stock to be issued in accordance with the preceding sentence, and rounding up to the nearest whole share and remitting such withholding in cash to the appropriate taxing authorities (the amount of such cash, the “RSU Withholding Amount”).

5.14 Homology ESPP. As soon as reasonably practicable following the date of this Agreement, the Homology Board shall adopt appropriate resolutions to provide that (a) no offering periods or purchase periods

shall be commenced following or in addition to the offering period underway as of the date hereof under the Homology ESPP (the “Current Offering Period”), (b) no payroll deductions or other contributions shall be made or effected after the Current Offering Period with respect to the Homology ESPP, and (c) each Homology ESPP participant’s accumulated contributions under the Homology ESPP shall be returned to the participant in accordance with the terms of the Homology ESPP.

5.15 Indemnification of Officers and Directors.

Each D&O Indemnified Party will be entitled to advancement of fees, costs and expenses incurred in the defense of any such claim, action, suit, proceeding or investigation from each of Homology and the Surviving Corporation, jointly and severally, upon receipt by Homology or the Surviving Corporation from the D&O Indemnified Party of a request therefor; provided that any such person to whom fees, costs or expenses are advanced provides an undertaking to Homology, to the extent then required by Delaware Law, to repay such advances if it is ultimately determined that such person is not entitled to indemnification. Homology and the Surviving Corporation shall each cooperate with the D&O Indemnified Party in the defense of any actual or threatened claim, action, suit, proceeding or investigation.

(b) The provisions of Homology’s Organizational Documents with respect to indemnification, advancement of expenses and exculpation of present and former directors and officers of Homology that are presently set forth in Homology’s Organizational Documents shall not be amended, modified or repealed for a period of six years from the Effective Time in a manner that would adversely affect the rights thereunder of individuals who, at or prior to the Effective Time, were officers or directors of Homology, unless such modification is required by applicable Law. The Surviving Corporation’s Organizational Documents shall contain, and Homology shall cause the certificate of incorporation of the Surviving Corporation to so contain, provisions no less favorable with respect to indemnification, advancement of fees, costs and expenses and exculpation of future, present and former directors and officers as those presently set forth in Homology’s and Q32’s Organizational Documents, respectively.

(c) From and after the Effective Time, (i) the Surviving Corporation shall fulfill and honor in all respects the obligations of Q32 to its D&O Indemnified Parties as of immediately prior to the Effective Time pursuant to any indemnification, exculpation and advancement provisions under Q32’s Organizational Documents and pursuant to any indemnification agreements between Q32 and such D&O Indemnified Parties, with respect to any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, formal or informal, arising out of matters occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time (including in connection with this Agreement or the Contemplated Transactions), and (ii) Homology shall fulfill and honor in all respects the obligations of Homology to its D&O Indemnified Parties as of immediately prior to the Closing pursuant to any indemnification provisions under Homology’s Organizational Documents and pursuant to any indemnification agreements between Homology and such D&O Indemnified Parties, with respect to claims arising out of matters occurring at or prior to the Effective Time.

In addition, Homology shall purchase, prior to the Effective Time, a six-year prepaid non-cancellable extension of directors’ and officers’ liability coverage of Homology’s existing directors’ and officers’ insurance policies for a claims reporting or discovery period of at least six years from and after the Effective Time with respect to any claim related to any period of time at or prior to the Effective Time “Homology D&O Tail Coverage” with the same or substantially the same terms, conditions, retentions and limits of liability as the coverage provided under Homology’s existing policies as of the date of this Agreement with respect to any actual or alleged error, misstatement, misleading statement, act, omission, neglect, breach of duty or any matter claimed against a director or officer of Homology by reason of him or her serving in such capacity that existed or occurred at or prior to the Effective Time (including in connection with this Agreement or the Contemplated Transactions or in connection with Homology’s initial public offering of shares of Homology Common Stock).

(e) From and after the Effective Time, each of Homology and the Surviving Corporation, jointly and severally, shall pay all expenses, including reasonable fees, costs and expenses, including attorneys’ fees and disbursements in advance, that are incurred by the persons referred to in this Section 5.15 in connection with their enforcement of the rights provided to such persons in this Section 5.15.

(f) The provisions of this Section 5.15 are intended to be in addition to the rights otherwise available to the current and former officers and directors of Homology and Q32 by Law, charter, statute, bylaw or agreement, and shall operate for the benefit of, and shall be enforceable by, each of the D&O Indemnified Parties, their heirs and their Representatives.

(g) In the event Homology or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of Homology or the Surviving Corporation, as the case may be, shall succeed to the obligations set forth in this Section 5.15. Homology shall cause the Surviving Corporation to perform all of the obligations of the Surviving Corporation under this Section 5.15.

5.16 Tax Matters.

(a) All transfer, documentary, sales, use, stamp, registration, excise, recording, registration value added and other such similar Taxes and fees (including any penalties and interest) that become payable by Q32 or Homology in connection with or by reason of the execution of this Agreement and the transactions contemplated hereby (collectively, “Transfer Taxes”) shall be borne and paid by Homology.

(c) The parties intend that, for United States federal income tax purposes, the Merger will qualify for the Intended Tax Treatment. The Merger shall be reported by the parties for all Tax purposes in accordance with the foregoing, unless otherwise required by a Governmental Authority as a result of a “determination” within the meaning of Section 1313(a) of the Code.

5.18 Legends. Homology shall be entitled to place appropriate legends on the book entries and/or certificates evidencing any shares of Homology Common Stock to be received in the Merger by equityholders of Q32 who may be considered “affiliates” of Homology for purposes of Rules 144 and 145 under the Securities Act reflecting the restrictions set forth in Rules 144 and 145 and to issue appropriate stop transfer instructions to the transfer agent for Homology Common Stock.

The representations and warranties of Homology and Merger Sub contained in this Agreement (other than the Homology Fundamental Representations and the Homology Capitalization Representations) shall have been true and correct in all respects as of the date of this Agreement and shall be true and correct on and as of the Closing Date with the same force and effect as if made on the Closing Date except (i) in each case, or in the aggregate, where the failure to be true and correct would not reasonably be expected to have a Homology Material Adverse Effect (without giving effect to any references therein to any Homology Material Adverse Effect or other materiality qualifications), (ii) where the failure to be true and correct as of the Closing Date is the result of (a) a Legacy Asset Disposition or (b) abandonment of or failure to file, prosecute or maintain any Abandoned Homology Legacy IP Rights (provided that this clause (ii) shall not cover any liability related to Legacy IP Rights (e.g., liability for infringement) that remains with the Company following Closing or (iii) for those representations and warranties which address matters only as of a particular date (which representations shall have been true and correct, subject to the qualifications as set forth in the preceding clause (i) and (ii), as of such particular date) (it being understood that, for purposes of determining the accuracy of such representations and warranties, any update of or modification to the Homology Disclosure Schedule made or purported to have been made after the date of this Agreement shall be disregarded).

(b) Homology and Merger Sub shall have performed or complied in all material respects with all covenants and agreements required to be performed or complied with by them under this Agreement at or prior to the Closing Date.

(d) Homology shall have delivered to Q32 a certificate (the “Homology Closing Certificate”), dated the Closing Date and signed by an executive officer of Homology, certifying to the effect that the conditions set forth in Sections 6.2(a) and 6.2(b) have been satisfied.

6.3 Conditions Precedent to Obligations of Homology. The obligations of Homology and Merger Sub to effect the Merger and otherwise consummate the Contemplated Transactions are subject to the satisfaction or, to the extent permitted by applicable law, the written waiver by Homology, at or prior to the Closing, of each of the following conditions:

(a) Each of the Q32 Fundamental Representations shall have been true and correct in all respects as of the date of this Agreement and shall be true and correct in all material respects on and as of the Closing Date with the same force and effect as if made on and as of such date (except to the extent such representations and warranties are specifically made as of a particular date, in which case such representations and warranties shall be true and correct as of such date). The Q32 Capitalization Representations shall have been true and correct in all respects as of the date of this Agreement and shall be true and correct on and as of the Closing Date with the

same force and effect as if made on and as of such date, except, in each case, (x) for such inaccuracies which are de minimis, individually or in the aggregate or (y) for those representations and warranties which address matters only as of a particular date (which representations and warranties shall have been true and correct, subject to the qualifications as set forth in the preceding clause (x), as of such particular date). The representations and warranties of Q32 contained in this Agreement (other than the Q32 Fundamental Representations and the Q32 Capitalization Representations) shall have been true and correct in all respects as of the date of this Agreement and shall be true and correct on and as of the Closing Date with the same force and effect as if made on the Closing Date except (i) in each case, or in the aggregate, where the failure to be so true and correct would not reasonably be expected to have a Q32 Material Adverse Effect (without giving effect to any references therein to any Q32 Material Adverse Effect or other materiality qualifications) or (ii) for those representations and warranties which address matters only as of a particular date (which representations shall have been true and correct, subject to the qualifications as set forth in the preceding clause (a), as of such particular date) (it being understood that, for purposes of determining the accuracy of such representations and warranties, any update of or modification to the Q32 Disclosure Schedule made or purported to have been made after the date of this Agreement shall be disregarded).

(b) Q32 shall have performed and complied in all material respects with all covenants and agreements required to be performed or complied with by it under this Agreement at or prior to the Closing Date.

6.4 Frustration of Closing Conditions. Neither Homology nor Merger Sub may rely on the failure of any conditions set forth in Sections 6.1 or 6.3 to be satisfied if the primary cause of such failure was the failure of Homology or Merger Sub to perform any of its obligations under this Agreement. Q32 may not rely on the failure of any conditions set forth in Sections 6.1 or 6.2 to be satisfied if the primary cause of such failure was the failure of Q32 to perform any of its obligations under this Agreement.

TERMINATION

8.1 Termination. This Agreement may be terminated, and the Merger and the Contemplated Transactions may be abandoned at any time prior to the Effective Time, whether before or (subject to the terms hereof) after approval of the Homology Stockholder Matters by Homology’s stockholders, unless otherwise specified below:

(a) by mutual written consent of Homology and Q32;

(b) by either Homology and Q32 if the Merger shall not have been consummated by May 16, 2024 (subject to possible extension as provided in this Section 8.1(b), the “Outside Date”); provided, however, that the right to terminate this Agreement under this Section 8.1(b) shall not be available to Homology or Q32 if such Party’s action or failure to act has been a principal cause of the failure of the Merger to occur on or before the Outside Date and such action or failure to act constitutes a breach of this Agreement, provided, further, however, that, in the event that the SEC has not declared effective under the Securities Act the Registration Statement by the date which is twenty-five (25) days prior to the Outside Date, then either Homology or Q32 shall be entitled to extend the Outside Date for an additional ninety (90) days;

(c) by either Homology and Q32 if a court of competent jurisdiction or other Governmental Authority shall have issued a final and nonappealable Order, or shall have taken any other action, having the effect of permanently restraining, enjoining or otherwise prohibiting the Contemplated Transactions;

(d) by Homology if the Required Q32 Stockholder Vote shall not have been obtained and evidence thereof delivered to Homology within fifteen (15) days of the Registration Statement becoming effective in accordance with the provisions of the Securities Act; provided, however, that once the Required Q32 Stockholder Vote has been obtained, Homology may not terminate this Agreement pursuant to this Section 8.1(d);

(e) by either Homology or Q32 if (i) the Homology Stockholder Meeting (including any adjournments and postponements thereof) shall have been held and completed and Homology’s stockholders shall have taken a final vote on the Homology Stockholder Matters and (ii) the Homology Stockholder Matters shall not have been approved at the Homology Stockholder Meeting (or at any adjournment or postponement thereof) by the Required Homology Stockholder Vote;

(f) by Q32 (at any time prior to the approval of the Homology Stockholder Matters by the Required Homology Stockholder Vote) if a Homology Triggering Event shall have occurred;

(g) by Homology (at any time prior to the adoption of this Agreement and the approval of the Contemplated Transactions by the Required Q32 Stockholder Vote) if a Q32 Triggering Event shall have occurred;

(h) by Q32, upon a breach of any representation, warranty, covenant or agreement set forth in this Agreement by Homology or Merger Sub or if any representation or warranty of Homology or Merger Sub shall have become inaccurate, in either case, such that the conditions set forth in Section 6.2(a) or Section 6.2(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become inaccurate; provided that Q32 is not then in material breach of any representation, warranty, covenant or agreement under this Agreement; provided, further, that if such inaccuracy in Homology’s or Merger Sub’s representations and warranties or breach by Homology or Merger Sub is curable by Homology or Merger Sub, then this Agreement shall not terminate pursuant to this Section 8.1(h) as a result of such particular breach or inaccuracy until the expiration of a 30-day period commencing upon delivery of written notice from Q32 to

Homology or Merger Sub of such breach or inaccuracy and its intention to terminate pursuant to this Section 8.1(h) (it being understood that this Agreement shall not terminate pursuant to this Section 8.1(h) as a result of such particular breach or inaccuracy if such breach by Homology or Merger Sub is cured prior to such termination becoming effective); or

(i) by Homology, upon a breach of any representation, warranty, covenant or agreement set forth in this Agreement by Q32 or if any representation or warranty of Q32 shall have become inaccurate, in either case, such that the conditions set forth in Section 6.3(a) or Section 6.3(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become inaccurate; provided that Homology is not then in material breach of any representation, warranty, covenant or agreement under this Agreement; provided, further, that if such inaccuracy in Q32’s representations and warranties or breach by Q32 is curable by Q32 then this Agreement shall not terminate pursuant to this Section 8.1(i) as a result of such particular breach or inaccuracy until the expiration of a 30-day period commencing upon delivery of written notice from Homology to Q32 of such breach or inaccuracy and its intention to terminate pursuant to this Section 8.1(i) (it being understood that this Agreement shall not terminate pursuant to this Section 8.1(i) as a result of such particular breach or inaccuracy if such breach by Q32 is cured prior to such termination becoming effective).

The Party desiring to terminate this Agreement pursuant to this Section 8.1 (other than pursuant to Section 8.1(a)) shall give a notice of such termination to the other Party specifying the provisions hereof pursuant to which such termination is made and the basis therefor described in reasonable detail.

8.2 Effect of Termination. In the event of the termination of this Agreement as provided in Section 8.1, this Agreement shall be of no further force or effect; provided, however, that (a) this Section 8.2, Section 8.3, and Article IX shall survive the termination of this Agreement and shall remain in full force and effect and (b) the termination of this Agreement and the provisions of Section 8.3 shall not relieve any Party of any liability for fraud or for any willful and material breach of any representation, warranty, covenant, obligation or other provision contained in this Agreement.

8.3 Expenses; Termination Fees.

(a) Except as set forth in this Section 8.3 all fees and expenses incurred in connection with this Agreement and the Contemplated Transactions shall be paid by the Party incurring such expenses, whether or not the Merger is consummated; provided, however, that (i) Homology and Q32 shall pay the costs and expenses incurred in relation to the filings by the Parties under any antitrust Law applicable to this Agreement and the transactions contemplated hereby, and (ii) Homology and Q32 shall share equally all fees and expenses incurred in relation to the printing and filing with the SEC of the Registration Statement (including any financial statements and exhibits) and any amendments or supplements thereto and paid to a financial printer or the SEC.

(b) If (i) this Agreement is terminated by Homology or Q32 pursuant to Section 8.1(b), (ii) at any time after the date of this Agreement and prior to the Homology Stockholder Meeting an Acquisition Proposal with respect to Homology shall have been publicly announced, disclosed or otherwise communicated to the Homology Board (and shall not have been withdrawn) and (iii) within twelve (12) months after the date of such termination, Homology enters into a definitive agreement with respect to a Subsequent Transaction or consummates a Subsequent Transaction, then Homology shall pay to Q32, within four (4) Business Days after termination (or, if applicable, upon such entry into a definitive agreement and/or consummation of a Subsequent Transaction), a nonrefundable fee in an amount equal to $2,400,000.

(c) If this Agreement is terminated by Q32 pursuant to Section 8.1(f), then Homology shall pay to Q32 within four (4) Business Days after termination, a nonrefundable fee in an amount equal to $2,400,000.

(d) If this Agreement is terminated by Homology pursuant to Section 8.1(d) or Section 8.1(g), then Q32 shall pay to Homology, within four (4) Business Days after termination, a nonrefundable fee in an amount equal to $5,850,000.

(e) If either Party fails to pay when due any amount payable by it under this Section 8.3, then (i) such Party shall reimburse the other Party for reasonable costs and expenses (including reasonable fees and disbursements of counsel) incurred in connection with the collection of such overdue amount and the enforcement by the other Party of its rights under this Section 8.3 and (ii) such Party shall pay to the other Party interest on such overdue amount (for the period commencing as of the date such overdue amount was originally required to be paid and ending on the date such overdue amount is actually paid to the other Party in full) at a rate per annum equal to the “prime rate” (as announced by Bank of America or any successor thereto) in effect on the date such overdue amount was originally required to be paid plus three percent.

(f) The Parties agree that, subject to Section 8.2, the payment of the fees and expenses set forth in this Section 8.3 shall be the sole and exclusive remedy of each Party following a termination of this Agreement under the circumstances described in this Section 8.3 that result in the payment of such fees, it being understood that in no event shall either Homology or Q32 be required to pay the individual fees or damages payable pursuant to this Section 8.3 on more than one occasion. Subject to Section 8.2, following the termination of this Agreement under the circumstances described in this Section 8.3 and the payment of the fees set forth in this Section 8.3 by a Party, (i) such Party shall have no further liability to the other Party in connection with or arising out of this Agreement or the termination thereof, any breach of this Agreement by the other Party giving rise to such termination, or the failure of the Contemplated Transactions to be consummated, (ii) no other Party or their respective Affiliates shall be entitled to bring or maintain any other claim, action or proceeding against such Party or seek to obtain any recovery, judgment or damages of any kind against such Party (or any partner, member, stockholder, director, officer, employee, Subsidiary, affiliate, agent or other representative of such Party) in connection with or arising out of this Agreement or the termination thereof, any breach by such Party giving rise to such termination or the failure of the Contemplated Transactions to be consummated and (iii) all other Parties and their respective Affiliates shall be precluded from any other remedy against such Party and its Affiliates, at law or in equity or otherwise, in connection with or arising out of this Agreement or the termination thereof, any breach by such Party giving rise to such termination or the failure of the Contemplated Transactions to be consummated. Each of the Parties acknowledges that (x) the agreements contained in this Section 8.3 are an integral part of the Contemplated Transactions, (y) without these agreements, the Parties would not enter into this Agreement and (z) any amount payable pursuant to this Section 8.3 is not a penalty, but rather is liquidated damages in a reasonable amount that will compensate the Parties in the circumstances in which such amount is payable.

ARTICLE IX

GENERAL PROVISIONS

9.1 Non-Survival of Representations and Warranties. The representations and warranties of Q32, Homology and Merger Sub contained in this Agreement or any certificate or instrument delivered pursuant to this Agreement shall terminate at the Effective Time, and only the covenants that by their terms survive the Effective Time and this Article IX shall survive the Effective Time.

9.2 Amendment. This Agreement may be amended with the approval of the respective boards of directors of Q32, Merger Sub and Homology at any time (whether before or after obtaining the Required Q32 Stockholder Vote and the Required Homology Stockholder Vote); provided, however, that after any such approval of this Agreement by a Party’s stockholders or members, no amendment shall be made which by Law requires further approval of such stockholders or members without the further approval of such stockholders or members. This Agreement may not be amended except by an instrument in writing signed on behalf of each of Q32, Merger Sub and Homology.

9.3 Waiver.

(a) Any provision hereof may be waived by the waiving Party solely on such Party’s own behalf, without the consent of any other Party. No failure on the part of any Party to exercise any power, right, privilege or

remedy under this Agreement, and no delay on the part of any Party in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy.

(b) No Party shall be deemed to have waived any claim arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such Party and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

9.4 Entire Agreement; Counterparts; Exchanges by Electronic Transmission or Facsimile. This Agreement and the other schedules, exhibits, certificates, instruments and agreements referred to in this Agreement constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among or between any of the Parties with respect to the subject matter hereof and thereof; provided, however, that the Confidentiality Agreement shall not be superseded and shall remain in full force and effect in accordance with its terms. This Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. The exchange of a fully executed Agreement (in counterparts or otherwise) by all Parties by facsimile or electronic transmission in PDF format shall be sufficient to bind the Parties to the terms and conditions of this Agreement.

9.5 Applicable Law; Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws. In any action or proceeding between any of the Parties arising out of or relating to this Agreement or any of the Contemplated Transactions, each of the Parties: irrevocably and unconditionally (a) consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware or, to the extent such court does not have subject matter jurisdiction, the Superior Court of the State of Delaware or the United States District Court for the District of Delaware, (b) agrees that all claims in respect of such action or proceeding shall be heard and determined exclusively in accordance with clause (a) of this Section 9.5, (c) waives any objection to laying venue in any such action or proceeding in such courts, (d) waives any objection that such courts are an inconvenient forum or do not have jurisdiction over any Party, (e) agrees that service of process upon such Party in any such action or proceeding shall be effective if notice is given in accordance with Section 9.7 of this Agreement and (f) irrevocably and unconditionally waives the right to trial by jury.

9.6 Assignability. This Agreement shall be binding upon, and shall be enforceable by and inure solely to the benefit of, the Parties and their respective successors and permitted assigns; provided, however, that neither this Agreement nor any of a Party’s rights or obligations hereunder may be assigned or delegated by such Party without the prior written consent of the other Party, and any attempted assignment or delegation of this Agreement or any of such rights or obligations by such Party without the other Party’s prior written consent shall be void and of no effect.

9.7 Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly delivered and received hereunder (a) one (1) Business Day after being sent for next Business Day delivery, fees prepaid, via a reputable international overnight courier service, (b) upon delivery in the case of delivery by hand or (c) on the date delivered in the place of delivery if sent by email or facsimile (with a written or electronic confirmation of delivery) prior to 6:00 p.m. New York City time, otherwise on the next succeeding Business Day, in each case to the intended recipient as set forth below:

9.8 Cooperation. Each Party agrees to cooperate fully with the other Party and to execute and deliver such further documents, certificates, agreements and instruments and to take such other actions as may be reasonably requested by the other Party to evidence or reflect the Contemplated Transactions and to carry out the intent and purposes of this Agreement.

9.9 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If a final judgment of a court of competent jurisdiction declares that any term or provision of this Agreement is invalid or unenforceable, the Parties agree that the court making such determination shall have the power to limit such term or provision, to delete specific words or phrases or to replace such term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be valid and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the Parties agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision.

9.10 Other Remedies; Specific Performance. 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 remedy will not preclude the exercise of any other remedy. The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms (including failing to take such actions as are required of it hereunder to consummate this Agreement) or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity, and each of the Parties waives any bond, surety or other security that might be required of any other Party with respect thereto. Each of the Parties further agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief on the basis that any other Party has an adequate remedy at law or that any award of specific performance is not an appropriate remedy for any reason at law or in equity.

9.11 No Third-Party Beneficiaries.

Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person (other than the Parties and the D&O Indemnified Parties to the extent of their respective rights pursuant to Section 5.15) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.
