The Sponsor has agreed not to transfer, assign or sell any of the Private Placement Warrants (except to certain permitted transferees) until 30 days after the completion of the Company’s initial business combination. The issuance of the Private Placement Warrants was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”).

On March 4, 2021, E. Perot Bissell, Mary Anne Brelinsky, Amy Francetic, Adam Grosser and Marvin Odum were appointed as members of the Board of Directors of the Company (the “Board”).

The Units were issued pursuant to an underwriting agreement, dated March 4, 2021, among the Company, on the one hand, and Barclays Capital Inc. and Goldman Sachs & Co. LLC on the other hand.
