Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Each share of each series of preferred stock was convertible at any time on a 1-for-0.3333 basis into Common Stock, at the holder's election, and each share of each series of preferred stock automatically converted upon the closing of the Issuer's initial public offering. The shares of each series of preferred stock had no expiration date.
(2) Artal Luxembourg S.A. is a wholly-owned subsidiary of Artal International S.C.A., which is a wholly-owned subsidiary of Artal Group S.A., which is a wholly-owned subsidiary of Westend S.A., which is a wholly-owned subsidiary of Stichting Administratiekantoor Westend. Each reporting person disclaims beneficial ownership of the securities reported herein except to the extent of his or her pecuniary interest therein, if any.
(3) The Convertible Subordinated Promissory Note (the "Convertible Note") was purchased by the reporting person in connection with an August 2011 financing. The Convertible Note automatically converted into shares of Common Stock upon the closing of the Issuer's initial public offering at a price per share equal to the public offering price with a 20% discount. Since the public offering price was $13.00, the conversion price per share is $10.40.
