Explanation of Responses:

1. The option, which is exercisable as it vests, will vest with respect to 25% of the shares on May 11, 2007 and thereafter continues to vest over a three-year period in equal annual installments.

Remarks:

The Issuer's Compensation Committee awarded the option as part of the 2006 annual grants to employees. The amount of shares and vesting of the option reflect the Compensation Committee's new framework for option vesting to commence and be based upon the option grant date, instead of the employment anniversary date. In connection with this new framework, the Compensation Committee pro-rated the amount of option shares awarded to the reporting person based upon the number of weeks that such person was employed since such person's 2005 employment hire date to the option grant date. Subsequent annual grants to such person, if any, will be awarded without any such pro-ration.
