Each Unit (“Unit”) consists
of one (1) share of Class A common stock, par value $0.0001 per share (“Common Stock”), of Kimbell
Tiger Acquisition Corporation, a Delaware corporation (the “Company”), and one-half of one redeemable warrant
to purchase one share of Class A common stock (each whole warrant, a “Warrant”). Each Warrant entitles
the holder thereof to purchase one (1) share (subject to adjustment) of Common Stock for $11.50 per share (subject to adjustment).
Each Warrant will become exercisable thirty (30) days after the Company’s completion of a merger, capital stock exchange, asset
acquisition, stock purchase, reorganization or other similar business combination with one or more businesses (each a “Business
Combination”) and will expire unless exercised before 5:00 p.m., New York City Time, on the date that is five (5) years
after the date on which the Company completes its initial Business Combination, or earlier upon redemption or liquidation (the “Expiration
Date”). The Class A common stock and warrants constituting the Units will begin separate trading on the 52nd day following
the date of the prospectus relating to the Company’s initial public offering (or, if such date is not a business day, the following
business day), unless UBS Securities LLC informs us of its decision to allow earlier separate trading, subject to the Company’s
filing with the Securities and Exchange Commission of a Current Report on Form 8-K containing an audited balance sheet reflecting
the Company’s receipt of the gross proceeds of the offering and issuing a press release announcing when separate trading will begin.
The terms of the Warrants are governed by a Warrant Agreement, dated as of [●], 2021, between the Company, Kimbell Tiger Operating
Company, LLC and Continental Stock Transfer & Trust Company, as Warrant Agent, and are subject to the terms and provisions contained
therein, all of which terms and provisions the holder of this certificate consents to by acceptance hereof. Copies of the Warrant Agreement

funds held in the trust account established in connection with the Company’s initial public offering only in the event that (i) the

public offering are redeemed in connection with a stockholder vote to approve an amendment to the Company’s amended and restated

combination activity, or (iii) if the holder(s) seek(s) to redeem for cash his, her or its respective shares of Common
Stock in connection with a tender offer (or proxy solicitation, solely in the event the Company seeks stockholder approval of the proposed
initial business combination) setting forth the details of a proposed initial business combination. In no other circumstances shall the
holder(s) have any right or interest of any kind in or to the trust account.
