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 3,296,588 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 24.6% 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.
