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) The Convertible Subordinated Promissory Note (the "Convertible Note") was purchased by Warburg Pincus Private Equity IX, L.P., a Delaware limited partnership ("WP IX"), in connection with an August 2011 financing. The Convertible Note is automatically convertible 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 price per share is $10.40. The offering price was determined on February 21, 2012, at which time the Convertible Note became a derivative security.
(2) Mr. Krieger, a director of the Issuer, is a Member and Managing Director of Warburg Pincus LLC, a New York limited liability company ("WP LLC"), which is the manager of WP IX. Mr. Krieger is also a Partner of Warburg Pincus & Co., a New York general partnership ("WP"), which is the managing member of Warburg Pincus Partners LLC, a New York limited liability company ("WP Partners"), which is the sole member of Warburg Pincus IX LLC, a New York limited liability company ("WP IX GP"), which is the general partner of WP IX. Messrs. Charles R. Kaye and Joseph P. Landy are the Co-Presidents and Managing Members of WP LLC and the Managing General Partners of WP and may be deemed to control WP IX, WP IX GP, WP Partners, WP and WP LLC.
(3) By reason of the provisions of Rule 16a-l of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), WP IX GP, WP Partners, WP, WP LLC and Messrs. Kaye, Landy and Krieger may be deemed to be the beneficial owners and have an indirect pecuniary interest in an indeterminate portion of the securities of the Issuer that may be deemed to be beneficially owned by WP IX. Each of WP IX GP, WP Partners, WP, WP LLC and Messrs. Kaye, Landy and Krieger disclaims beneficial ownership of such securities that may be deemed to be beneficially owned by WP IX, except to the extent of any pecuniary interest therein. This Form 4 shall not be deemed an admission that any reporting person or any other person referred to herein is a beneficial owner of any securities of the Issuer for purposes of Section 16 of the Exchange Act, or for any other purpose or that any reporting person or other person has an obligation to file this Form 4.
