WHEREAS, pursuant to the terms and conditions set forth in the Business Combination Agreement, at the effective time of the Second Merger (the
“Second Effective Time”), by virtue of the Second Merger and without any further action on the part of any Party hereto or the Registered Holders, New PubCo shall assume the Existing Warrant Agreement pursuant to the terms set forth
herein; 
 WHEREAS, Section 9.8 of the Existing Warrant Agreement provides that JCIC and the Warrant Agent may
amend the Existing Warrant Agreement without the consent of any Registered Holder for the purpose of curing any ambiguity contained in the Existing Warrant Agreement, including to conform the provisions of the Existing Warrant Agreement to the
description of the terms of the Warrants, or adding or changing any provisions with respect to matters or questions arising under the Existing Warrant Agreement as JCIC and the Warrant Agent may deem necessary or desirable and that JCIC and the
Warrant Agent deem shall not adversely affect the rights of the Registered Holders under the Existing Warrant Agreement; 
 WHEREAS,
pursuant to the terms and conditions of each of the Existing Warrant Agreement and the Business Combination Agreement, at the Second Effective Time, by virtue of the Second Merger and without any action on the part of any Registered Holders, each
Warrant that is outstanding immediately prior to the Second Effective Time shall, pursuant to and in accordance with Section 4 of the Existing 












 
Warrant Agreement, automatically and irrevocably be modified to provide that such Warrant shall no longer entitle the holder thereof to purchase the number of Ordinary Shares set forth therein
and in substitution thereof such Warrant shall entitle the holder thereof to acquire such number of shares of common stock of New PubCo, par value $0.0001 per share (“New PubCo Common Stock”), per Warrant, subject to adjustments as
provided in Section 4 and the last sentence of Section 3.1 of the Existing Warrant Agreement, that such holder would have received pursuant to the terms and conditions of the Existing Warrant
Agreement; and 
 WHEREAS, as a result of this Warrant Assumption Agreement, each Warrant outstanding immediately prior to the Second
Effective Time will be exchanged for a warrant to purchase New PubCo Common Stock pursuant to the terms and conditions of the Existing Warrant Agreement. 

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, JCIC, New PubCo and the Warrant Agent hereby agree as follows: 
 1. Assignment and Assumption. 

(a) Upon and subject to the occurrence of the Second Effective Time, JCIC hereby assigns, and New PubCo hereby assumes, the rights and
obligations of JCIC under the Existing Warrant Agreement and the Warrants, including the obligation to issue Ordinary Shares upon the exercise of the Warrants, and New PubCo hereby agrees to faithfully perform, satisfy and discharge when due, the
liabilities and obligations of JCIC under the Existing Warrant Agreement and the Warrants. As a result of the preceding sentence, upon and subject to the occurrence of the Second Effective Time, each Warrant will be exchanged for a warrant to
purchase New PubCo Common Stock pursuant to the terms and conditions of the Existing Warrant Agreement. 
 (b) This Warrant Assumption
Agreement is being executed and delivered pursuant and subject to the Existing Warrant Agreement. Nothing in this Warrant Assumption Agreement shall, or shall be deemed to, defeat, limit, alter, impair, enhance or enlarge any right, obligation,
claim or remedy created by the Existing Warrant Agreement or any other document or instrument delivered pursuant to or in connection with it. 
 2.
Amendment of Existing Warrant Agreement. 
 (a) JCIC, New PubCo, and the Warrant Agent hereby amend the Existing Warrant Agreement as
provided in this Section 2 effective immediately prior to the Second Effective Time and conditions on the occurrence of the Closing, and acknowledge and agree that the amendments to the Existing Warrant Agreement set forth
in this Section 2 are necessary or desirable and that such amendments do not adversely affect the interests of the Registered Holders. 

(b) All references to “Jack Creek Investment Corp., a Cayman Islands exempted company” in the Existing Warrant Agreement (including
all Exhibits thereto) shall refer instead to “Bridger Aerospace Group Holdings, Inc., a Delaware corporation.” As a result thereof, all references to the “Company” in the Existing Warrant Agreement shall be references to Bridger
Aerospace Group Holdings, Inc. or New PubCo rather than to Jack Creek Investment Corp. or JCIC. 
 (c) Reference to Ordinary Shares.
All references to “Class A ordinary shares” of JCIC and “$0.0001 par value” in the Existing Warrant Agreement shall refer instead to “shares of common stock” of New PubCo and “with a par value of $0.0001 per
share”, respectively. As a result thereof, all references to “Ordinary Shares” in the Existing Warrant Agreement shall be references to New PubCo’s Common Stock rather than to JCIC’s Class A ordinary shares.
