| (a) | Amount beneficially owned:
The information required by this item with respect to each reporting person is set forth on rows 5 through 9 and 11 of the cover page to this Schedule 13G and is incorporated herein by reference for each such reporting person.
On August 4, 2026, after taking into account trades settling on August 5, 2026 as described below, Ascent directly owns 502,813 shares of Common Stock. In addition, as of August 4, 2026, there are 1,107,753 shares of Common Stock issuable pursuant to the Warrant, with such amount being the maximum issuable pursuant to the Blocker. The shares held directly by Ascent and the remaining shares issuable (up to the Blocker) pursuant to the Convertible Notes and the warrants are collectively referred to herein as the "Shares".
The Shares directly owned were acquired as follows: (i) as part of the completion of the offering of Shares described in its Prospectus (Registration No. 333-297627), filed on July 28, 2026 Ascent acquired 1,140,000 units of the Issuer, each consisting of 1 share of common stock, par value 0.01 of the Issuer (the "Common Stock") and a warrant to purchase one share of Common Stock (each a "Warrant"), (ii) on July 28, 2026, July 29, 2026 and July 30, 2026 Ascent sold 980,000, 130,000 and 30,000 shares of Common Stock respectively, (iii) on July 31, 2026, Ascent partially exercised the Warrants to acquire 571,429 shares of Common Stock, (iv) on August 3, 2026, Ascent sold 207,969 shares of Common Stock, (v) on August 4, Ascent sold 328,460 shares of Common Stock and (vi) on August 4, 2026, Ascent partially exercised the Warrants to acquire 1,360,000 shares of Common Stock and entered into binding trades to sell 892,187 shares.
The ownership percentages reported above are based on 13,082,612 shares of Common Stock outstanding (excluding shares of Common Stock issuable under the Warrants) as of the completion of the offering of Shares described in its Prospectus (Registration No. 333-297627), filed on July 28, 2026, (ii) 1,931,429 Shares issued upon exercise of the Warrants since July 28, 2026 (or to be issued pursuant to the exercise notice sent on August 4, 2026 under the Warrants) and (ii) 1,107,753 shares of Common Stock issuable by the Issuer upon partial exercise of the Warrant directly held by the reporting person, subject to a provision contained therein limiting beneficial ownership to an aggregate maximum of 9.99% (the "Blocker").
Due to the Blocker, Ascent is currently prohibited from fully exercising the Warrant. The percentage set forth on row (11) and the number of shares of Common Stock set forth on rows (6), (8) and (9) of the cover page for each reporting person give effect to the Blocker for the Warrant. Consequently, as of August 4, 2026, each of the reporting persons are not deemed to be beneficial owners of the full amount of shares of Common Stock issuable upon conversion exercise of the Warrant.
The percentage set forth on row (11) above and the number of shares of Common Stock set forth on rows (6), (8) and (9) above includes shares of Common Stock up to the Blocker (as defined in this footnote) amount, the partial exercise of a warrant to purchase Common Stock (the "Warrant") held directly by the reporting person. The Warrant is subject to a provision contained therein limiting beneficial ownership to an aggregate maximum of 9.99% (the "Blocker").
