FORM OF AMENDMENT NO. 1 TO PRE-FUNDED WARRANT
This AMENDMENT NO. 1 TO PRE-FUNDED WARRANT (this “Amendment”) is effective as of March 26, 2026 by and between Q32 Bio Inc., a Delaware corporation (the “Company”) and [_____]. (the “Holder”). Each of the Company and the Holder shall be referred to collectively as the “Parties” and individually as a “Party.”
W I T N E S S E T H:
WHEREAS, the Company issued the Holder a pre-funded warrant (the “Pre-Funded Warrant”) to purchase shares of the Company’s common stock, $0.0001 par value per share (the “Common Stock”), in the amounts set forth on the Pre-Funded Warrant, pursuant to the terms of a registered direct offering which closed on February 19, 2026;
WHEREAS, the Parties desire to amend certain provisions of the Pre-Funded Warrant pursuant to Section 5(l) of the Pre-Funded Warrant, as set forth below.
NOW, THEREFORE, in consideration of the mutual promises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each of the Parties agree with the others as follows:
1.Unless otherwise defined herein, all terms and conditions used in this Amendment shall have the meanings assigned to such terms in the Pre-Funded Warrant.
2.Section 3(e) of the Pre-Funded Warrant is hereby deleted in its entirety and replaced with the following:
“(e) Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company (or any Subsidiary), directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of the Company’s assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of more than 50% of the voting power of the common equity of the Company, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off, merger or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires more than 50% of the voting power of the common equity of the Company, (each, a “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section 2(e) on the exercise of this Warrant), the number of shares of capital stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to
any limitation in Section 2(e) on the exercise of this Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. The Company shall cause any successor entity to the Company, surviving entity or other Person, including any Purchaser of assets of the Company in a Fundamental Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant and the other Transaction Documents in accordance with the provisions of this Section 3(e) pursuant to written agreements in form and substance reasonably satisfactory to the Holder prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall be added to the term “Company” under this Warrant (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead to each of the Company and the Successor Entity or Successor Entities, jointly and severally), and may exercise every right and power of the Company and the Successor Entity or Successor Entities shall assume all of the obligations of the Company under this Warrant and the other Transaction Documents with the same effect as if the Company and such Successor Entity or Successor Entities, jointly and severally, had been named as the Company herein, after which, for the avoidance of doubt, the provisions of this paragraph (e) shall similarly apply to any subsequent Fundamental Transaction.”
3.No MNPI. The Company hereby agrees and acknowledges that the amendment contemplated by this Amendment does not constitute material nonpublic information of the Company or any of its subsidiaries and that the Holder is not subject to any confidentiality or similar obligations under any agreement, whether written or oral, between the Company, any of its subsidiaries or any of their respective officers, directors, affiliates, employees or agents, on the one hand, and the Holder or any of the Holder’s affiliates, on the other hand. The Company understands and confirms that the Holder and its affiliates will rely on the foregoing representations in effecting transactions in securities of the Company.
4.Registration Statement. The Company hereby agrees and acknowledges that the Registration Statement on Form S-3 (File No. 333-286491) remains available after giving effect to this Amendment for the issuance of the shares of Common Stock issuable upon exercise from time to time of the Pre-Funded Warrant without any need to file any amendment or supplement thereto.
5.Further Assurances. Each Party hereto, without additional consideration, shall cooperate, shall take such further action and shall execute and deliver such further documents as may be reasonably requested by the other Party hereto in order to carry out the provisions and purposes of this Amendment.
6.Counterparts. This Amendment may be signed in counterparts with the same effect as if the signature on each counterpart were upon the same instrument. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.
7.Headings. The headings of Articles and Sections in this Amendment are provided for convenience only and will not affect its construction or interpretation.
8.Waiver. Neither any failure nor any delay by any party in exercising any right, power or privilege under this Amendment or any of the documents referred to in this Amendment will operate as a waiver of such right, power or privilege, and no single or partial exercise of any such right, power or privilege will preclude any other or further exercise of such right, power or privilege.
9.Severability. The invalidity or unenforceability of any provisions of this Amendment pursuant to any applicable law shall not affect the validity of the remaining provisions hereof, but this Amendment shall be construed as if not containing the provision held invalid or unenforceable in the jurisdiction in which so held, and the remaining provisions of this Amendment shall remain in full force and effect. If the Amendment may not be effectively construed as if not containing the provision held invalid or unenforceable, then the provision contained herein that is held invalid or unenforceable shall be reformed so that it meets such requirements as to make it valid or enforceable.
10.Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Amendment shall be determined in accordance with the provisions of the Pre-Funded Warrant.
