“ WHEREAS, in connection with the SPAC Continuance and the occurrence of the Closing, the Sponsor Shares will automatically be converted into shares of common stock of New PubCo (“New Pubco Common Shares”) pursuant to the Governing Documents of SPAC and the Sponsor Warrants will be assumed by New PubCo and be converted into the right to exercise such warrants for New PubCo Common Shares (collectively, the “Automatic Conversion”);”

(b) The fifth Recital of the Sponsor Side Letter is hereby amended and restated in its entirety as follows:

“ WHEREAS, the Sponsor Shares and Sponsor Warrants not forfeited hereunder shall continue to be subject to the Automatic Conversion; provided, that, the Automatic Conversion shall provide for the automatic conversion of each Sponsor Share into one New PubCo Common Share times the Reverse Split Factor (as such term is defined in the BCA Amendment) (rounded down to the nearest whole share after aggregating all New PubCo Common Shares held by the Sponsor) and each Sponsor Warrant will be converted into a right to exercise such warrants for a number of New PubCo Common Shares as adjusted by the Reverse Split Factor in accordance with the terms of the Warrant Agreement; and”

“1.11 Waiver of Adjustment Provisions. Notwithstanding anything to the contrary in any other document, agreement or contract to which Sponsor is bound, Sponsor (for itself, himself or herself and for its, his or her successors, heirs, assigns and permitted transferees) hereby (but subject to the consummation of the Amalgamation) irrevocably and unconditionally waives and agrees not to exercise or assert, any rights to adjustment or other anti-dilution protections with respect to the rate at which shares of SPAC Class B Shares convert into other shares of SPAC or New PubCo Common Shares in connection with the Automatic Conversion and, in furtherance of the foregoing, Sponsor hereby irrevocably and unconditionally agrees and acknowledges that, in connection with the SPAC Continuance and the occurrence of the Closing, (a) each SPAC Class B Share (other than those subject to the Automatic Sponsor Share Forfeiture or the Financing Sponsor Share Forfeiture) shall convert only into a number of New PubCo Common Shares (and not any other SPAC shares prior to the Automatic Conversion) equal to the Reverse Split Factor and (b) that each Sponsor Warrant shall only convert into the right to exercise such warrants for New PubCo Common Shares equal to the Reverse Split Factor, such waiver, agreement and acknowledgement constituting sufficient and necessary waiver under the terms of SPAC’s certificate of incorporation as currently in effect for such purpose, in each case subject to equitable adjustments for any Pre-Closing Splits to provide the same economic effect as contemplated by this Side Letter prior to such Pre-Closing Split; provided, that, no fractional shares shall be issued and the total number of New PubCo Common Shares to be received by the Sponsor shall be rounded down to the nearest whole share after aggregating all New PubCo Common Shares held by the Sponsor.”
