2.That the Board of Directors duly adopted resolutions proposing to amend and restate the Certificate of Incorporation of this corporation, declaring said amendment and restatement to be advisable and in the best interests of this corporation and its stockholders, and authorizing the appropriate officers of this corporation to solicit the consent of the stockholders therefor, which resolution setting forth the proposed amendment and restatement is as follows:

RESOLVED, that the Certificate of Incorporation of this corporation be amended and restated in its entirety to read as follows:

First: The name of this corporation is MAIA Biotechnology, Inc. (the “Corporation”).

Third: The purpose of the Corporation is to engage in any lawful business or activity for which corporations may be organized under the DGCL and, in general, to possess and exercise all the powers and privileges granted by the DGCL, any other law of the State of Delaware, or the Certificate of Incorporation, together with any powers incidental thereto, so far as such powers and privileges are necessary or convenient to the conduct, promotion, or attainment of the business or purposes of the Corporation.

Fourth: This Corporation is authorized to issue two classes of shares of stock, which shall be designated, respectively, “Common Stock’’ and “Preferred Stock.” The total number of shares that the Corporation is authorized to issue is 100,000,000 shares. The number of shares of Common Stock authorized is 70,000,000 shares, $0.0001 par value per share. The number of shares of Preferred Stock authorized is 30,000,000 shares, $0.0001 par value per share. The rights, privileges, preferences and restrictions of the Preferred Stock shall be as set forth in one or more resolutions providing for the issuance of such stock adopted by the Corporation’s Board of Directors pursuant to authority expressly vested in it by this Article fourth”

Fifth: The Directors, subject to any rights of the holders of shares of any class or series of preferred stock of the Corporation, shall be classified with respect to the time for which they severally hold office into three classes, as nearly equal in number as possible. The Board of Directors may assign members of the Board already in office to a particular class. Directors shall be assigned to each class in accordance with a resolution or resolutions adopted by the Board. The term of each Director shall continue until the election and qualification of a successor and be subject to such Director’s earlier death, resignation or removal. At each annual meeting of stockholders of the Corporation, subject to any rights of the holders of shares of any class or series of preferred stock of the Company, the successors of the Directors whose term expires at that meeting shall be elected to hold office for a term expiring at the annual meeting of stockholders held in the third year following the year of their election.

Sixth: In furtherance and not in limitation of the powers conferred by the laws of the State of Delaware, the Board of Directors of the Corporation is expressly authorized to make, alter, and repeal the bylaws of the Corporation, subject to the power of the stockholders of the Corporation to alter or repeal any bylaw whether adopted by the stockholders or otherwise.

Seventh: Unless and except to the extent that the bylaws of the Corporation shall so require, the election of directors of the Corporation need not be by written ballot.

Eighth: To the fullest extent permitted by the DGCL, as the same may be amended from time to time, a director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director. If the DGCL is hereafter amended to authorize, with or without the approval of a corporation’s stockholders, further reductions in the liability of the Corporation’s directors for breach of fiduciary duty, then a director of the Corporation shall not be liable for any such breach to the fullest extent permitted by the DGCL, as so amended. Any repeal or modification of this Article EIGHTH, or the adoption of any provision of the Corporation’s Certificate of Incorporation inconsistent with this Article EIGHTH, shall only be prospective and shall not adversely affect the rights under this Article EIGHTH in effect at the time of the alleged occurrence of any action or omission to act giving rise to liability.

Ninth: To the fullest extent permitted by applicable laws of the State of Delaware, the Corporation is authorized to provide indemnification of (and advancement of expenses to) directors, officers, employees, and other agents of the Corporation (and any other persons to which DGCL permits the Corporation to provide indemnification), through bylaw provisions, agreements with any such director, officer, employee, consultant or other agent, or other person, vote of stockholders or disinterested directors, or otherwise, in excess of the indemnification and advancement otherwise permitted by Section 145 of the DGCL, subject only to limits created by the provisions of applicable law (statutory or non- statutory), with respect to actions for breach of duty to a corporation, its stockholders, and others. Any repeal or modification of any of the foregoing provision of this Article NINTH, by amendment of this Article NINTH or by operation of law, shall not adversely affect any right or protection of a director, officer, employee or other agent or other person existing at the time of, or increase the liability of any director of the Corporation with respect to any acts or omissions of such director, officer, or agent occurring prior to such repeal or modification.

Tenth: Except as provided in the last sentence of Article EIGHTH and Article NINTH, the Corporation reserves the right at any time, and from time to time, to amend, alter, change, or repeal any provision contained in this Certificate of Incorporation, and other provisions authorized by the laws of the State of Delaware at the time in force may be added or inserted, in the manner now or hereafter prescribed by law; and all rights, preferences, and privileges of whatsoever nature conferred upon stockholders, directors or any other persons whomsoever by and pursuant to this Certificate of Incorporation in its present form or as hereafter amended are granted subject to the rights reserved in this article.

Eleventh: Meetings of stockholders and meetings of the board of directors may be held within or without the State of Delaware, as may be determined from time to time by the Board of Directors. Furthermore, the Board of Directors may, in its sole discretion, determine that the meeting of stockholders or meeting of the board of directors shall not be held at any place, but may instead be held solely by means of remote communication (i.e., conference call, Internet meeting, etc.). The books of the Corporation may be kept (subject to any provision contained in the statutes) outside of the State of Delaware at such place or places as may be designated from time to time by the Board of Directors or in the bylaws of the Corporation.

No action shall be taken by the stockholders of the Corporation except at an annual or special meeting of stockholders called in accordance with the bylaws of the Corporation, and no action shall be taken by the stockholders of the Corporation by written consent or by electronic transmission.

Twelfth: Any action required or permitted to be taken at any meeting of the Board of Directors or of any committee thereof may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing setting forth the action so taken shall be signed by all of the Directors or committee members, as applicable, and such consent or consents shall be delivered to an officer or agent of the corporation by hand, regular mail, facsimile, e-mail or similar electronic transmission.

Thirteenth: Unless the Corporation consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if and only if the Court of Chancery of the State of Delaware lacks subject matter jurisdiction, any state court located within the State of Delaware or, if and only if all such state courts lack subject matter jurisdiction, the federal district court for the District of Delaware) shall be the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law (i) any derivative action or proceeding brought on behalf of the Corporation; (ii) any action or proceeding asserting a claim of breach of a fiduciary duty owed by any current or former director, officer or other employee of the Corporation, to the Corporation or the Corporation’s stockholders; (iii) any action or proceeding asserting a claim against the Corporation or any current or former director, officer or other employee of the Corporation, arising out of or pursuant to any provision of the DGCL, this Certificate of Incorporation or the Bylaws (as each may be amended from time to time) or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware; (iv) any action or proceeding to interpret, apply, enforce or determine the validity of this Certificate of Incorporation or the Bylaws (including any right, obligation, or remedy thereunder); (v) any action or proceeding as to which the DGCL confers jurisdiction to the Court of Chancery of the State of Delaware; (vi) any action by any director, officer or agent of the

Corporation for indemnification pursuant to this Certificate of Incorporation, the Bylaws or any indemnification agreements; and (v) any action asserting a claim against the Corporation or any director, officer or other employee of the Corporation, governed by the internal affairs doctrine, in all cases to the fullest extent permitted by law and subject to the court’s having personal jurisdiction over the indispensable parties named as defendants. In any action as to which the Court of Chancery of the State of Delaware determines that there is an indispensable party not subject to the personal jurisdiction of the Court of Chancery of the State of Delaware (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery of the State of Delaware within ten (10) days following such determination), in which case the United States District Court for the District of Delaware or other state courts of the State of Delaware, as applicable, shall, to the fullest extent permitted by law, be the sole and exclusive forum for any such claims. This Article XII shall not apply to suits brought to enforce a duty or liability created by the Securities Act of 1933, as amended (the “Securities Act”), the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or any other claim for which the federal courts have exclusive jurisdiction. Unless the Corporation consents in writing to the selection of an alternative forum, the federal district courts of the District of Delaware shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act or the Exchange Act. Any person or entity purchasing or otherwise acquiring or holding any interest in any securities of the Corporation shall be deemed to have notice of and consented to the provisions of this Certificate of Incorporation generally and this Article XII in particular.
