SPAC Sponsor, Terms That Would Result in Earlier Expiration of Restrictions [Text Block]	In addition, in order to facilitate our initial business combination or for any other reason determined by our sponsor in its sole discretion, our sponsor may surrender or forfeit, transfer or exchange our founder shares, private placement warrants or any of our other securities, including for no consideration, or otherwise amend the terms of any such securities or enter into any other arrangements with respect to any such securities. Although such actions are subject to the transfer and other restrictions affecting founder shares and private placement warrants set forth in the letter agreement and described elsewhere in this prospectus, there are no restrictions on the general partner’s ability to transfer equity interests held by the general partner or otherwise consent to a transfer by another limited partner, and transfers of equity interests in the sponsor or its direct or indirect parent entities may result in a change of ownership or control of the sponsor. See “Risk Factors — Risks Relating to our Sponsor and Management Team — A change of ownership or control of the sponsor could adversely affect our ability to consummate our initial business combination.”
