Private Placement Units Purchase Agreement between the Issuer and Sponsor

On January 7, 2026, simultaneously with the consummation of the IPO, Sponsor purchased 530,000 Placement Units pursuant to the Purchase Agreement. The Placement Units and the securities underlying such Placement Units are subject to a lock up provision in the Insider Letter, which provides that such securities shall not be transferable, saleable or assignable until 30 days after the consummation of the Issuer's initial business combination, subject to certain limited exceptions as described in the Insider Letter.

The description of the Purchase Agreement is qualified in its entirety by reference to the full text of such agreement, a copy of which was filed by the Issuer as Exhibit 10.4 to the Current Report on Form 8-K filed by the Issuer with the SEC on January 8, 2026 (and is incorporated by reference herein as Exhibit 10.1).

Insider Letter

In connection with the IPO, the Issuer, Sponsor, Advisors and Mr. Cohen, and certain other parties thereto, entered into a letter agreement (the "Insider Letter"). Pursuant to the Insider Letter, the parties agreed to waive: (i) their redemption rights with respect to their Class B Shares and public shares in connection with the completion of the initial business combination, (ii) their redemption rights with respect to any Class B Shares and public shares held by them in connection with a shareholder vote to amend the Issuer's charter (A) to modify the substance or timing of Issuer's obligation to allow redemption in connection with its initial business combination or to redeem 100% of its public shares if it does not complete its initial business combination within 24 months (or 27 months, as applicable) from the closing of the IPO or (B) with respect to any other provision relating to shareholders' rights or pre-initial business combination activity; and (iii) their rights to liquidating distributions from the Issuer's trust account with respect to Class B Shares if the Issuer fails to complete its initial business combination within 24 months (or 27 months, as applicable) from the closing of the IPO (although they will be entitled to liquidating distributions from the trust account with respect to any public shares they hold if the Issuer fails to complete its initial business combination within the prescribed time frame). Sponsor also agreed that in the event of the liquidation of the Trust Account of the Issuer (as defined in the Insider Letter), it will indemnify and hold harmless the Issuer against any and all loss, liability, claims, damage and expense whatsoever which the Issuer may become subject to as a result of any claim by any vendor or other person who is owed money by the Issuer for services rendered or products sold to or contracted for the Issuer, or by any target business with which the Issuer has discussed entering into a transaction agreement, but only to the extent necessary to ensure that such loss, liability, claim, damage or expense does not reduce the amount of funds in the Trust Account; provided that such indemnity shall not apply if such vendor or prospective target business executes an agreement waiving any claims against the Trust Account.

In addition, in the event that the underwriter of the Issuer's IPO does not exercise its over-allotment option to purchase up to an additional 3,300,000 units, pursuant to the Insider Letter, Advisors has agreed to forfeit, at no cost, up to 1,100,000 Class B Shares. No units were purchased by the underwriter pursuant to its over-allotment option as part of the IPO.

The description of the Insider Letter is qualified in its entirety by reference to the full text of such agreement, a copy of which was filed by the Issuer as Exhibit 10.1 to the Current Report on Form 8-K filed by the Issuer with the SEC on January 8, 2026 (and is incorporated by reference herein as Exhibit 10.2).

Registration Rights Agreement

In connection with the IPO, the Issuer, Sponsor, Advisors and certain other parties entered into a registration rights agreement pursuant to which certain demand and "piggyback" registration rights were granted, which will be subject to customary conditions and limitations, including the right of the underwriters of an offering to limit the number of shares offered.

The summary of such registration rights agreement contained herein is qualified in its entirety by reference to the full text of such agreement, a copy of which was filed by the Issuer as Exhibit 10.3 to the Current Report on Form 8-K filed by the Issuer with the SEC on January 8, 2026 (and is incorporated by reference herein as Exhibit 10.3).
