** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Shares reported herein may be held by Pura Vida Master Fund, Ltd. (the "Pura Vida Master Fund"), Pura Vida Pro Special Opportunity Master Fund, Ltd. (the "Pura Vida Pro Fund"), or certain separately managed accounts (the "Accounts"). Pura Vida Investments, LLC ("PVI") serves as the investment manager to the Pura Vida Master Fund and the Accounts. Pura Vida Pro, LLC ("PVP") serves as the investment manager to the Pura Vida Pro Fund. PVP is a relying adviser of PVI. Efrem Kamen serves as the Managing Member of both PVI and PVP.
(2) The securities reported herein may be deemed beneficially owned by each of: (i) PVI, which is deemed the beneficial owner of shares held by the Pura Vida Master Fund, the Pura Vida Pro Fund, and the Accounts (collectively, the "Client Accounts") in its capacity as investment manager on behalf of itself and PVP as its relying advisor, and (ii) Efrem Kamen who serves as the Managing Member of both PVI and PVP. Mr. Kamen exercises voting and dispositive control over the securities and is therefore deemed to be a beneficial owner of securities owned or controlled by PVI. Each of PVI and Mr. Kamen disclaim beneficial ownership of the reported securities held by the Client Accounts, except to the extent of its or his pecuniary interest therein.
