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) This amendment is being filed to correct an inadvertent error in the original filing, which indicated that the reporting person had been granted an award of 70,464 shares of restricted stock. The correct amount granted was 52,848 restricted shares while the remaining 17,616 shares were awarded in the form of restricted stock units. See Table II and footnotes #2 and #3 below for further information.
(2) Not Applicable. Each Restricted Stock Unit ("RSU") represents the right to receive one share of the Company's common stock upon vesting without payment.
(3) Not Applicable. The RSU award vests in one-third annual increments beginning upon the first anniversary of the grant date, subject to the reporting person's continued employment with the Company and subject to accelerated vesting upon death, disability or retirement of the reporting person, or upon a change in control.

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.
