Explanation of Responses:
(1)  Each share of common stock was purchased together with one warrant to purchase 0.5 shares of common stock at a combined offering price of $1.3325.
(2)  Shares reported herein are owned by Pura Vida Master Fund, Ltd. (the "Pura Vida Master Fund"), Pura Vida X Fund LP (the "Pura Vida X Fund"), Lockheed Martin Corporation Master Retirement Trust (the "Retirement Trust"), and certain separately managed accounts (the "Managed Accounts," collectively the "Client Accounts"). Pura Vida Investments, LLC ("PVI") serves as the investment manager or sub-adviser to the Client Accounts. Efrem Kamen serves as the Managing Member of PVI.
(3)  By virtue of these relationships, the Reporting Persons may be deemed to have shared voting and dispositive power with respect to the securities owned directly by the Client Accounts. This report shall not be deemed an admission that the Reporting Persons are beneficial owners of the securities for purposes of Sections 13 and 16 of the Securities Exchange Act of 1934, as amended, or for any other purpose. Each of the Reporting Persons disclaims beneficial ownership of the securities reported herein except to the extent of the Reporting Person's pecuniary interest therein, if any.
(4)  The Warrants are subject to an ownership blocker provision that prevents the holder from exercising the Warrants if it would beneficially hold more than 19.99% of the common stock following such exercise.
