The termination of the Rights Agreement shall terminate the rights of the parties thereto to enforce any provisions of such agreement that expressly survive the termination of the Rights Agreement. Each Class B Holder hereby waives any right to notice, right of first offer, right of first refusal or similar rights with respect to the Transaction, in each case that such Class B Holder may have under the Rights Agreement.

3. Vesting.

(a) The Class B Holders and the Company agree that, as of immediately prior to (but subject to) the Closing, all of the shares of Acquiror Class B Common Stock and Acquiror Common Stock issuable upon conversion of Acquiror Class B Common Stock in connection with the Closing held by the Class B Holders as of immediately prior to the Closing (the “SPAC Shares”) shall be unvested and shall become subject to the vesting and forfeiture provisions set forth in this Section 3 following the Closing (pro rata based on each Class B Holder’s relative ownership of SPAC Shares).

(b) 6,900,000 SPAC Shares, which represent 80% of the outstanding SPAC Shares, shall vest (and shall not be subject to forfeiture) at the Closing.

(c) 1,725,000 SPAC Shares, which represent 20% of the outstanding SPAC Shares (the “SPAC Vesting Shares”), shall vest (and shall not be subject to forfeiture) upon the date on which the Acquiror Common Stock’s volume weighted average price on the NASDAQ as reported by Bloomberg is greater than $12.50 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any twenty (20) trading days within any thirty (30) consecutive trading day period during the Vesting Period. Any SPAC Vesting Shares that have not vested, pursuant to this Section 3(c) or Section 3(d), by the end of the Vesting Period shall be deemed to be transferred by the forfeiting holder to the Acquiror without any consideration and shall be cancelled by the Acquiror and cease to exist.

(d) In the event that a Company Sale is consummated during the Vesting Period that will result in the holders of Acquiror Common Stock receiving a Company Sale Price equal to or in excess of $12.50 (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like), then immediately prior to the consummation of such Company Sale, to the extent it has not already occurred, the vesting condition set forth in Section 3(c) above shall be deemed to have occurred (and such unvested SPAC Vesting Shares shall become vested) and the holders of such SPAC Vesting Shares shall be eligible to participate in such Company Sale in the same manner as other holders of shares of Acquiror Common Stock. Notwithstanding anything to the contrary herein, in the event of any merger, sale, consolidation, business combination, recapitalization, capital stock exchange, tender offer, reorganization or other similar business transaction that does not constitute a Company Sale, any unvested SPAC Vesting Shares shall not be forfeited, shall remain outstanding, and shall remain subject to vesting as set forth in Section 3(c).

(e) Each holder of SPAC Vesting Shares shall be responsible for making an election in accordance with Section 83(b) of the Code in respect of its SPAC Vesting Shares. IT IS THE SOLE RESPONSIBILITY OF EACH SUCH HOLDER OF SPAC VESTING SHARES, AND NOT OF THE ACQUIROR OR SPONSOR (OR ANY OF THEIR AFFILIATES OR REPRESENTATIVES), TO MAKE AN ELECTION UNDER SECTION 83(B) OF THE CODE, EVEN IF SUCH HOLDER REQUESTS THAT THE ACQUIROR OR SPONSOR (OR ANY OF THEIR AFFILIATES OR REPRESENTATIVES) ASSIST IN MAKING SUCH ELECTION. EACH SUCH HOLDER THAT MAKES AN ELECTION UNDER SECTION 83(B) OF THE CODE WITH RESPECT TO SUCH SPAC VESTING SHARES SHALL PROVIDE A COPY OF SUCH ELECTION TO THE ACQUIROR ON OR BEFORE THE DUE DATE FOR MAKING SUCH ELECTION.

(f) For purposes of this Section 3:

(i) “Company Sale” means (which, for the avoidance of doubt, shall not include the Transactions): (x) any transaction or series of related transactions that results in any Person or “group” (within the meaning of Section 13(d)(3) of the Exchange Act) acquiring Equity Securities that represent more than 50% of the total voting power of the then outstanding voting securities of Acquiror (or the Equity Securities of the surviving Person outstanding immediately after such transaction or transactions) or (y) a sale or disposition of all or substantially all of the assets of Acquiror and its Subsidiaries on a consolidated basis, in each case other than a transaction or series of related transactions which results in at least 50% of the combined voting power of the then outstanding voting securities of Acquiror (or any successor to Acquiror) immediately following the closing of such transaction or series of related transactions beneficially owned, directly or indirectly, by individuals and entities (or Affiliates of such individuals and entities) who were the beneficial owners, respectively, of Equity Securities representing more than 50% of the total voting power of the then outstanding voting securities of Acquiror immediately prior to such transaction or series of related transactions.

(ii) “Company Sale Price” means the price per share for Acquiror Common Stock in a Company Sale as determined by the value ascribed to such Acquiror Common Stock in the definitive agreement relating to such Company Sale. If and to the extent the price paid per share in the Company Sale includes any escrows, holdbacks, deferred purchase price, earnouts or other contingent consideration that is payable to the holders of Acquiror Common Stock in such Company Sale (together, “Contingent Consideration”), the Acquiror Board shall determine the fair market value of any such Contingent Consideration as of the Closing Date in good faith. If and to the extent the consideration payable to the holders of Acquiror Common Stock in such Company Sale includes consideration other than cash and the value of such consideration is not specified in or determined by the definitive agreement relating to such Company Sale, the price for such non-cash consideration shall be determined by the Acquiror Board in good faith.

(iii) “Vesting Period” means the period beginning on the Closing Date and ending five (5) years following the Closing Date.

(b) Each Class B Holder hereby acknowledges and agrees that, immediately prior to the Effective Time, and subject to Section 4(a), each share of Acquiror Class B Common Stock that is issued and outstanding as of such time shall automatically convert into one share of Acquiror Class A Common Stock, and each Class B Holder jointly and severally agree that as a result of such conversion, the 8,625,000 outstanding shares of Acquiror Class B Common Stock shall collectively convert into 8,625,000 shares of Acquiror Class A Common Stock (subject to the vesting provisions set forth in Section 3 and ordinary equitable adjustments on account of any stock splits, stock dividends, reorganizations, recapitalizations and the like).

(c) Each Class B Holder waives any and all rights to convert any working capital loans made by such Class B Holder or any of its Affiliates into Acquiror Warrants or any other securities that may be issuable upon conversion of such Working Capital Loans.
