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 disposed are unvested restricted shares forfeited as a result of the reporting person's retirement as President and CEO on 12/31/17. Of the total shares forfeited, 7,200 shares (75%) are from the 1/22/16 restricted stock award grant and 11,500 (100%) are from the 3/15/17 restricted stock award granted to the reporting person.
(2)	The reporting person disclaims beneficial ownership of these securities, and this report shall not be deemed to be an admission that the reporting person is the beneficial owner of such securities for purposes of Section 16 or for any other purpose.
(3)	The options disposed are unvested employee stock options forfeited as a result of the report person's retirement on 12/31/17.
(4)	The option is 25% vested and exercisable, but will expire on 12/31/18, the one year anniversary of the reporting person's retirement.
(5)	The options disposed are unvested employee stock options forfeited as a result of the reporting person's retirement on 12/31/17. The option was completely unvested and therefore was 100% forfeited as of 12/31/17.
