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) As disclosed in the registrants annual report on Form 10-K for the year ended December 31, 2016, on December 20, 2016, the reporting person was granted an option to purchase 197,707 shares of common stock. The option vests in two equal annual installments based on the registrant's satisfaction of certain performance criteria for the fiscal year ending December 2017. The performance criteria for 2017 were met, resulting in vesting of the option as follows: 98,854 shares vested on March 8, 2018 and 98,853 shares will vest on March 8, 2019. No Form 4 filing was required upon the initial grant of the option because the option was subject to vesting based on conditions that were not tied to the passage of time and continued employment and not tied directly to the market price of the registrant's common stock.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.

Potential persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB number.
