Explanation of Responses:
( 1 )The amount of securities beneficially owned has been reduced by 45,802 shares due to the inadvertent misclassification of the shares in the previous Form 4 filing by the reporting person. Such shares were granted as restricted stock units ("RSU") and should have been reported in table II. See table II of this Form 4 and footnote #3 below.
( 2 )Not applicable. Each RSU represents the right to receive one share of the Company's common stock upon vesting without payment.
( 3 )As noted in footnote #1 above, the previous Form 4 filing inadvertently misclassified 45,802 shares. Thus, the amount of RSUs shown in column 7 of Table II has been increased by this amount in order to correctly set forth the number of outstanding RSUs.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
* 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).

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