**	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 Company granted 5,605 restricted shares under the Company's Long-Term Incentive Program. The shares were subject to certain restrictions under the applicable Restricted Stock Grant Agreements. 1,187 of the 3,210 shares that vested October 26, 2018 were withheld to cover withholding taxes due upon vesting.
(2)	In connection with a Separation Agreement and General Release (SA&GR) between the Company and the reporting person, 1,050 shares previously reported as beneficially owned in connection with Restricted Stock Grant Agreements were forfeited.
(3)	On February 15, 2018, the reporting person was granted an option to purchase 5,030 shares of common stock scheduled to vest in installments of 20%, 40%, and 40% per year over the three-year period. The option reported herein as acquired resulted from the acceleration of vesting of 22.5% of such option in connection with a SA&GR.
