        <amountBeneficiallyOwned>The ownership information presented below represents beneficial ownership of the shares of Common Stock, based upon 15,926,939 shares of Common Stock outstanding as of October 14, 2025, as disclosed in the Issuer's Current Report on Form 8-K filed with the Securities and Exchange Commission on October 14, 2025. The share amounts reported herein reflect a 1-for-15 reverse stock split of the Common Stock effected by the Issuer on February 24, 2025.

J. Wood Capital Advisors LLC is the record holder of 784,802 shares of Common Stock and 215,906 warrants to purchase an equal number of shares of Common Stock.
