WHEREAS, the transactions contemplated by the Business Combination Agreement are referred to herein as the “Business Combination”;

WHEREAS, upon consummation of the Business Combination, as provided in Section 4.5 of the Existing Warrant Agreement, the Warrants will no longer be exercisable for shares of common stock of the Company but instead will be exercisable (subject to the terms of the Existing Warrant Agreement as amended hereby) for New Pubco common stock;

WHEREAS, in connection with the Business Combination, the Company desires to assign all of its right, title and interest in the Existing Warrant Agreement to New Pubco and New Pubco wishes to accept such assignment; and

WHEREAS, Section 9.8 of the Existing Warrant Agreement provides that the Company and the Warrant Agent may amend the Existing Warrant Agreement without the consent of any Registered Holders (i) to evidence the succession of another corporation to the Company and the assumption by any such successor of the covenants of the Company contained in the Warrant Agreement and the Warrants, or (ii) as the parties may deem necessary or desirable and that the parties deem shall not adversely affect the rights of the Registered Holders in any material respect under the Existing Warrant Agreement.

NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows:

Effective as of the First Effective Time, the Company and the Warrant Agent hereby amend the Existing Warrant Agreement as provided in this Section 2, and acknowledge and agree that the amendments to the Existing Warrant Agreement set forth in this Section 2 are to provide for the delivery of the kind and amount of shares of stock or other securities or property (including cash) receivable upon reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Warrants would have received if such holder had exercised his, her or its Warrant(s) immediately prior to such event pursuant to Section 4.5 of the Existing Warrant Agreement (in connection with the Business Combination and the transactions contemplated by the Business Combination Agreement).

“[INTENTIONALLY OMITTED]”
