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 shares are directly held by New Enterprise Associates 10, Limited Partnership ("NEA 10") and indirectly held by NEA Partners 10, Limited Partnership ("NEA Partners 10"), the sole general partner of NEA 10, and the individual general partners of NEA Partners 10 (NEA Partners 10 and its individual general partners together, the "Indirect Reporting Persons"). The individual general partners of NEA Partners 10 are Peter J. Barris, M. James Barrett and Scott D. Sandell. Each Indirect Reporting Person disclaims beneficial ownership within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, or otherwise of such portion of the NEA 10 shares in which such Indirect Reporting Person has no pecuniary interest.
(2) On November 16, 2015, NEA 10 exercised warrants to purchase a total of 9,445 shares of the Issuer's common stock for $0.33 a share. NEA 10 paid the exercise price on a cashless basis, resulting in the Issuer's withholding of 452 of the warrant shares to pay the exercise price and issuing 8,993 shares to NEA 10. The Issuer also paid cash to NEA 10 in lieu of any fractional shares to be issued upon exercise of the warrants.
