SPAC Sponsor and Affiliates Information, Restrictions on Sale of SPAC Securities [Table Text Block]

Pursuant to a letter agreement to be entered with us, each of our Sponsor, directors and officers has agreed to restrictions on its ability to transfer, assign, or sell the founder shares and private placement units.

The Sponsor has provided a working capital loan to us in the aggregate amount of up to $400,000 for the payment of expenses. As of June 30, 2026, $205,000 was outstanding under such working capital loan, with $195,000 remaining available for future borrowings.

In addition, in order to finance transaction costs in connection with an intended initial business combination, our Sponsor, executive officers, directors, or their affiliates may, but are not obligated to, loan us funds as may be required, which we refer to as working capital loans. At the option of the Sponsor, up to $200,000 in principal of these working capital loans entered into after the offering may be repaid in loan units.
