As the Chairman and Chief Executive Officer of the Issuer, Mr. Pompliano has in the past and may receive future compensation in the form of Common Stock, options or other securities convertible into Common Stock. Professional Capital Management has entered into an agreement with the Issuer pursuant to which Professional Capital Management has agreed not to, without the prior written consent of the Issuer, sell, offer to sell, or otherwise transfer or dispose of any Common Stock received by Professional Capital Management in connection with the BCA until the earlier of (i) the six (6) month anniversary of the December 5, 2025, or (ii) the date on which the Issuer consummates a subsequent liquidation, merger, capital stock exchange, reorganization, or similar transaction which results in all of the stockholders of the Issuer having the right to exchange their shares of Common Stock for cash, securities or other property. Professional Capital Management also entered into an amended and restated registration rights agreement, dated December 5, 2025, by and among CCCM, the Issuer, Professional Capital Management, Jeff Park (collectively with Professional Capital Management, the "ProCap Holders"), and Columbus Circle I Sponsor Corp LLC, a Delaware limited liability company (the "Sponsor"), pursuant to which the registration rights agreement dated as of May 15, 2025, by and among CCCM, the Sponsor, and the underwriters in the CCCM initial public offering, will be assumed by the Issuer and provide the ProCap Holders with registration rights thereunder covering, among other securities, the shares of Common Stock. In connection with the Silvia Merger, Professional Capital Management entered into that certain lock-up agreement with the Issuer (the "Silvia Merger Lock-Up Agreement") pursuant to which the Silvia Merger Shares are subject to transfer restrictions for a period ending on the later of (A) the six-month anniversary of the Closing Date and (B) the date on which the price of the Common Stock equals or exceeds the $9.00 per share (subject to adjustment for stock dividends, splits, and similar recapitalizations). Any additional shares received as earnout consideration pursuant to the Silvia Merger Agreement (the "Earnout Shares"), if any, are subject to a six-month lock-up following the Earnout Release Date (as defined in the Silvia Merger Agreement). The Silvia Merger Lock-Up Agreement contains customary exceptions for transfers to affiliates, family members, trusts, and for tax obligations, among others. In addition, pursuant to the Silvia Merger Agreement, for a period of two (2) years following the Closing Date, Professional Capital Management is subject to a separate restriction prohibiting participation in any repurchase by the Issuer of Common Stock. In connection with the Silvia Merger, Professional Capital Management also entered into that certain registration rights agreement with the Issuer (the "Registration Rights Agreement"), pursuant to which the Issuer agreed to register the resale of the Silvia Merger Shares and Earnout Shares, if issued. Pursuant to the Registration Rights Agreement, a majority-in-interest of the then outstanding Registrable Securities (as defined in the Registration Rights Agreement) may make a written demand for registration of all or part of their Registrable Securities as soon as practicable, but not more than 45 days after the Issuer's receipt of the demand for registration. The Issuer will not be obligated to effect more than three registrations pursuant to a demand registration. Professional Capital Management may at any time request in writing that the Issuer register the resale of any or all of the Registrable Securities on Form S-3 or any similar short-form registration statement within 30 days, provided, however, that the Issuer will not be obligated to effect such request through an underwritten offering or if Form S-3 is not available. The Registration Rights Agreement also provides customary piggyback registration rights (subject to underwriter cutbacks) and allows the Issuer to postpone or withdraw the filing or effectiveness of a piggyback registration at any time in its sole discretion. Furthermore, the Registration Rights Agreement includes certain restrictions on registration rights if in the Issuer's good faith the registration would be seriously detrimental to the Issuer. In such case, the Issuer will have the right to defer such filing for a period of not more than 30 days; provided, however, that the Issuer will not defer its obligation in this manner more than once in any 12-month period. The Registration Rights Agreement includes customary indemnification and contribution provisions and provides that the Issuer will bear registration expenses (excluding underwriting discounts and commissions and fees of Professional Capital Management's counsel above an agreed cap). Registration rights will terminate with respect to Professional Capital Management when Professional Capital Management's shares may be sold without restriction under Rule 144, subject to customary conditions. There currently are no other contracts, arrangements, understandings or relationships (legal or otherwise) between the Reporting Persons and any other person with respect to any securities of the Issuer, including, but not limited to, transfer or voting of any other securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.
