The managing member of Western Standard and the portfolio manager to the Funds is Mr. Andersen. Each of Western Standard and Mr. Andersen disclaims beneficial ownership of the shares except to the extent of its or his pecuniary interest therein, if any, and this report shall not be deemed an admission that it or he is the beneficial owner of such shares.
F5 This Form 4/A is being filed to address a clerical error in reporting the number of shares beneficially owned following an acquisition of shares in a transaction on April 14, 2021. The correct number of shares beneficially owned following such transaction by the indirect beneficial owner set forth in footnote (2) to this Form 4/A was 947,306, rather than 947,396 as originally reported. In addition, this amendment corrects a clerical error in the calculation of the aggregate number of shares beneficially owned by the "13D Group," as set forth in the Remarks below. The correct number of shares beneficially owned by the 13D Group is 2,818,441, rather than 2,788,755 as originally reported.
F6 In addition to the corrections described in footnote (5) to this Form 4/A, this amendment is being filed to report a transaction on July 1, 2021, pursuant to which WSP acquired 52,914 shares from WSP QP. The aggregate shares held by WSP and WSP QP, who file jointly as reporting persons, did not change following this transaction.

Remarks:

As a result of an agreement among the persons listed below to vote their respective shares of Common Stock jointly, such persons have formed a "group" under Section 13(d)(1) of the Exchange Act. In addition to Mr. Andersen, Western Standard, LLC ("Western Standard"), Western Standard Partners, L.P. ("WSP") and Western Standard Partners QP, L.P. ("WSP QP" and together with WSP, the "Funds") (collectively, the "Western Standard Parties"), the members of this group are Noah G. Levy, Newtyn Management, LLC, Newtyn Partners, Newtyn TE Partners, LP, Newtyn Capital Partners, LP, and Ledo Capital, LLC (collectively, the "Newtyn Parties" and collectively with the Western Standard Parties, the "13D Group"). As a member of the 13D Group, each Western Standard Party would be deemed to beneficially own the aggregate amount of the Common Stock that each of the 13D Group members beneficially owns, in which case it or he would be deemed to beneficially own 2,818,441 shares of Common Stock. However, none of the Western Standard Parties have the ability to direct the acquisition or disposition or, except through the Cooperation Agreement, voting of the securities held by Newtyn Parties, and none of the Newtyn Parties have the ability to direct the acquisition or disposition or, except through the Cooperation Agreement, voting of the securities held by the Western Standard Parties. As members of the 13D Group, the combined holdings of the Western Standard Parties and the Newtyn Parties would result in each Western Standard Party having voting power equivalent to a combined beneficial ownership of 21.0% of the Issuer's outstanding Common Stock for voting purposes. Each Western Standard Party disclaims beneficial ownership of the shares beneficially owned by the 13D Group except to the extent of its or his pecuniary interest therein, if any, and this report shall not be deemed an admission that it or he is the beneficial owner of such shares.
