Explanation of Responses:

( 1 )The two reported transactions involved an amendment of an outstanding option, resulting in the deemed cancellation of the "old" option and the grant of a replacement option. The option was originally granted on July 30, 2007 and provides for vesting as follows: 12.5% of the shares vest on the date that is six (6) months after the Grant Date; the remaining shares vest in forty-two (42) equal monthly installments beginning on the date that is seven (7) months after the Grant Date.

Remarks: All of the items reported on this form involve the amendment of an outstanding option as a result of the Reporting Person entering into new executive employment and change-in-control agreements with the Issuer providing for an extension of the post-termination exercise period upon specified terminations of employment. The option amount reported on this form does not reflect exercises under the old option prior to the date of the deemed cancellation.

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