The Shares deliverable upon such exercise, as adjusted from time to time, are hereinafter sometimes referred to as “Warrant Shares,” and the exercise price for a Share in effect at any time, as adjusted from time to time, is hereinafter sometimes referred to as the “Exercise Price.” This Warrant is pursuant and subject to the Warrant Agreement dated [                ], 2022 (the “Warrant Agreement”) between the Company and Continental Stock Transfer & Trust Company (the “Warrant Agent”). A copy of the Warrant Agreement is available upon request to the Company.

(a)    EXERCISE OF WARRANT. This Warrant may be exercised in whole or in part at any time on or after the date 30 days after the consummation by the Company of its initial merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or similar business combination with one or more businesses or entities (the “Business Combination”) (as described more fully in the Registration Statement on Form S-1 (No. 333-264597) as filed with the Company, and terminating at 5:00 p.m., Eastern time on five years from the consummation of the Business Combination (the “Expiration Date”). Each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at the close of business on the Expiration Date. The Company in its sole discretion may extend the duration of the Warrants by delaying the

Expiration Date; provided, however, that the Company will provide at least ten (10) days’ prior written notice of any such extension to registered holders of the Warrants and, provided further that any such extension shall be identical in duration among all the Warrants.

(1)    This Warrant may be exercised by presentation and surrender hereof to the Company at its principal office with the Purchase Form annexed hereto (the “Purchase Form”) duly executed and accompanied by payment of the Exercise Price for the number of Warrant Shares specified in such Purchase Form (which may take the form of a “cashless exercise” pursuant to Section (a)(2) if so indicated in the Purchase Form).

(2)    The Holder shall pay the Exercise Price in immediately available funds; provided, however, that this Warrants may be exercised on a cashless basis at any time after notice of redemption shall have been given by the Company pursuant to Section (a)(2) and prior to the Redemption Date (as defined in Section 6.2 of the Warrant Agreement); provided that the Company may require the Holder to elect cashless exercise as set forth under this Section (a)(2) and the Holder must exercise this Warrant on a cashless basis if the Company so requires. In such event, the Holder shall satisfy its obligation to pay the Exercise Price through a “cashless exercise”, in which event the Company shall issue to the Holder the number of Warrant Shares determined as follows:

X = Y(A-B)/A

where

X = the number of Warrant Shares to be issued to the Holder.

Y = the total number of Warrant Shares with respect to which this Warrant is being exercised.

A = the Fair Market Value (as defined below) of one Share on the trading day immediately preceding the date on which Holder elects to exercise this Warrant by means of a “cashless exercise.”

B = the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.

For purposes of this Warrant, “Fair Market Value” means, for any security as of any date, the price determined by the first of the following clauses that applies: (a) if the Shares are then listed on a national securities exchange, the average reported last sale price of the Shares for the 10 trading days ending on the third trading day prior to the date of exercise, (b) if the Shares are quoted on the OTC Bulletin Board or the OTC Market, the average closing bid price on such market for the five most recently completed trading days, (c) if paragraphs (a) or (b) are not applicable, if an appraiser hired by the Company has provided a report on the fair market value of a Share within the 12-month period preceding the date on which Holder exercises this Warrant by means of a “cashless exercise,” the fair market value of a share of Shares as determined by such appraiser, or (d) if none of the foregoing is applicable, the price determined by the Board of Directors of the Company in good faith.

(b)    EFFECTIVE TIME OF EXERCISE. Each exercise of this Warrant shall be deemed to have been effected immediately prior to the close of business on the day on which the Purchase Form has been delivered to the Company (the “Exercise Date”) as provided in Section (a). At such time, the person or persons in whose name or names any certificates for Warrant Shares shall be issuable upon such exercise as provided in Section (c) below shall be deemed to have become the holder or holders of record of the Warrant Shares represented by such certificates.

2

Notwithstanding the foregoing, if the Holder or any assignee does not enter into the Shareholders’ Agreement within three (3) business days of being requested to do so by the Company, then the exercise of this Warrant will be deemed to not have been effective and void ab initio and the Holder or any assignee shall return any securities received by them pursuant to Section (c) to the Company.

(c)    DELIVERY TO HOLDER.

(1)    As soon as practicable after the exercise of this Warrant in whole or in part, and in any event within five (5) business days thereafter, the Company will cause to be issued in the name of, and delivered to, the Holder, or as such Holder (upon payment by such Holder of any applicable transfer taxes) may direct:

(A)    a certificate or certificates for the number of Warrant Shares to which such Holder shall be entitled, and

(B)    in case such exercise is in part only, a new warrant or warrants of like tenor, exercisable for in the aggregate the number of Shares equal (giving effect to any adjustment therein) to the number of Shares called for on the face of this Warrant minus the number of such shares purchased by the Holder upon such exercise.

(2)    To the extent permitted by law and except as provided in this Warrant, the Company’s obligations to issue and deliver Warrant Shares in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any person or entity or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other person or entity of any obligation to the Company or any violation or alleged violation of law by the Holder or any other person or entity, and irrespective of any other circumstance that might otherwise limit such obligation of the Company to the Holder in connection with the issuance of Warrant Shares. Nothing herein shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing Warrant Shares upon exercise of the Warrant as required pursuant to the terms hereof.

(d)    RESERVATION OF SHARES. The Company shall at all times reserve for issuance and/or delivery upon exercise of this Warrant such number of Shares (as adjusted pursuant to the terms hereof) as shall be required for issuance and delivery upon exercise of this Warrant. The Company covenants that all Warrant Shares so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and nonassessable. The Company will take all such action as may be reasonably necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of any securities exchange or automated quotation system upon which the Shares may be listed.

(e)    FRACTIONAL SHARES. No fractional shares or scrips representing fractional shares shall be issued upon the exercise of this Warrant. With respect to any fraction of a share called for upon any exercise hereof, the Company shall pay to the Holder an amount in cash equal to such fraction multiplied by the fair market value of a Share.
