The reporting person undertakes to provide to the Issuer, any security holder of the Issuer, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares purchased at each separate price within the ranges set forth in this footnote (1) to this Form 4.
2. The shares are directly held by NP. The general partner of the Funds is NCP. The general partner of NCP is Ledo. The investment manager to the Funds is Newtyn Management. The managing member of Newtyn Management and Ledo and the portfolio manager to the Funds is Mr. Levy. Each of Newtyn Management, Ledo, NCP and Mr. Levy 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.
3. The shares are directly held Newtyn TE. The general partner of the Funds is NCP. The general partner of NCP is Ledo. The investment manager to the Funds is Newtyn Management. The managing member of Newtyn Management and Ledo and the portfolio manager to the Funds is Mr. Levy.

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. Levy, Newtyn Management, LLC ("Newtyn Management"), Newtyn Partners, LP ("NP"), Newtyn TE Partners, LP ("Newtyn TE" and together with NP, the "Funds"), Newtyn Capital Partners, LP ("NCP") and Ledo Capital, LLC ("Ledo") (collectively, the "Newtyn Parties"), the members of this group are Eric D. Andersen, Western Standard, LLC, Western Standard Partners, LP and Western Standard Partners QP, LP (the "Western Standard Parties" and collectively with the Newtyn Parties, the "13D Group"). As a member of the 13D Group, each Newtyn 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 2,061,462 shares of Common Stock. However, 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 Western Standard Parties, and 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 the Newtyn Parties. As members of the 13D Group, the combined holdings of the Newtyn Parties and the Western Standard Parties would result in each Newtyn Party having voting power equivalent to a combined beneficial ownership of 15.4% of the Issuer's outstanding Common Stock for voting purposes. Each Newtyn 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.
