Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 5(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	These securities are directly owned by certain private investment funds (the "Private Funds") and may be deemed to be beneficially owned by (a) Whitebox Advisors LLC by virtue of its role as the investment manager of the Private Funds and (b) Whitebox General Partner LLC by virtue of its role as the general partner of the Private Funds.
(2)	Each Reporting Person disclaims beneficial ownership of the reported securities except to the extent of its pecuniary interest therein, and this report shall not be deemed an admission that such Reporting Person is the beneficial owner of the securities for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or for any other purpose.
(3)	These warrants (the "Jones Act Warrants") are immediately exercisable, subject to certain restrictions on ownership of the Issuer's capital stock by non-U.S. citizens, including a beneficial ownership limitation (the "Beneficial Ownership Limitation") that prevents any holder that cannot establish to the Issuer's reasonable satisfaction that it is a "U.S. Citizen" within the meaning of the U.S. citizenship and cabotage laws commonly referred to as the "Jones Act" (principally 46 U.S.C. Section 50501(a), (b), and (d) and 46 U.S.C. Chapters 121 and 551) from exercising the Jones Act Warrants to the extent that, after giving effect to the issuance of shares of Common Stock upon such exercise, the holder would beneficially own more than 4.9% of the shares of Common Stock outstanding.
(4)	These warrants have no expiration date.
(5)	The Private Funds own an aggregate 2,885,061 Jones Act Warrants, each exercisable for 10.27167 shares of Common Stock, without giving effect to the Beneficial Ownership Limitation. Based solely on the application of the Beneficial Ownership Limitation to each Private Fund individually, and based on 222,166,587 shares of Common Stock outstanding as of September 9, 2026, provided by the Issuer, the Jones Act Warrants held by the Private Funds would be exercisable for up to an aggregate 21,435,064 shares of Common Stock.
(6)	The exercise price of these warrants is $0.00001 per share.
