WHEREAS, the Company, the Representative, and Kingswood are parties to that certain Underwriting Agreement, dated August 5, 2025 (the “Underwriting Agreement”);
WHEREAS, the parties desire to amend the Underwriting Agreement to revise the calculation and payment terms of the Deferred Underwriting Commission; and

“1.3 Deferred Underwriting Commission. The Underwriters agree that 4.00% of the gross proceeds from the sale of the Firm Units ($2,880,000) and the Option Units (up to $432,000), if any (collectively, the “Deferred Underwriting Commission”), will be deposited and held in the Trust Account and payable directly from the Trust Account, without accrued interest, to the Representative for its own account upon consummation of the Company’s initial Business Combination. The Underwriters acknowledge and agree that the Deferred Underwriting Commission shall be payable only to the extent of, and shall in no event exceed, an amount equal to 4.00% of the funds remaining in the Trust Account after giving effect to all properly submitted redemptions in connection with the initial Business Combination. Each Underwriter, severally and not jointly, reserves the right in its sole discretion to waive the Deferred Underwriting Commission at any time prior to the initial Business Combination by providing written notice to the Company. In the event that the Company is unable to consummate a Business Combination and CST, as the trustee of the Trust Account (in this context, the “Trustee”), commences liquidation of the Trust Account as provided in the Trust Agreement, the Underwriters agree that: (i) they shall forfeit any rights or claims to the Deferred Underwriting Commission; and (ii) the Deferred Underwriting Commission, together with all other amounts on deposit in the Trust Account, shall be distributed on a pro-rata basis among the Public Shareholders.”
