### Footnotes:

(1) Each share of Series A Convertible Participating Preferred Stock, $0.0001 par value per share ("Series A Preferred Stock"), is convertible into one share of common stock, par value $0.0001 per share ("Common Stock") of the Issuer at any time at the option of the holder, subject to certain adjustments such as in connection with stock dividends, distributions, stock splits and stock combinations.

(2) Each share of Series A Preferred Stock held by the Equatorial Trust (the "Trust"), a family trust settled by Peter Beck and Kerryn Beck, will automatically convert into one share of Common Stock, upon the earliest to occur of (a) the any sale, assignment, transfer, conveyance, hypothecation or other transfer or disposition of such share of Series A Preferred Stock, except for certain permitted transfers described in the Issuer's amended and restated certificate of incorporation, as amended; (b) the first date on which the Peter Beck shall no longer serve as the Chief Executive Officer or such other executive officer position of the Issuer as approved by its Board of Directors; (c) the death or permanent disability of Peter Beck; or (d) the first date on which the outstanding shares of Series A Preferred Stock no longer represent at least 5% of the beneficial ownership of the Issuer's outstanding Common Stock.

(3) On June 17, 2025, the Trust optionally converted 5,000,000 shares of Series A Preferred Stock into 5,000,000 shares of Common Stock pursuant to the terms of the Series A Preferred Stock Certificate of Designation.  The Trust converted the shares for purposes of satisfying delivery of shares of Common Stock to the broker for sales to be made in future months under a Rule 10b5-1 Plan adopted by the Trust on June 13, 2025. The first date that shares are permitted to be sold under the Rule 10b5-1 Plan is September 15, 2025 and the Plan will expire under its terms on December 17, 2025.

(4) These shares are held directly by the Trust. Peek Street Equatorial Trustee Limited (the "Trustee") is the trustee of the Trust and each of Peter Beck, Kerryn Beck and Warren Butler serve as a director of the Trustee with shared voting and investment control of the shares and, as a result, the Trustee and each such individual is deemed to be an indirect beneficial owner of these securities. Each reporting person disclaims beneficial ownership of these securities, except to the extent, if any, of his, her or its pecuniary interest therein, and the filing of this Form 4 is not an admission that any reporting person is the beneficial owner of these securities for purposes of Section 16 or for any other purpose.
