Explanation of Responses:

1. Represents shares of restricted common stock granted June 28, 2005 (the "Grant Date") withheld by the Company solely for the purpose of satisfying tax obligations arising upon the vesting of a portion of the restricted common stock awarded on the Grant Date.

2. Includes 14,485 shares of Restricted Common Stock, which is subject to vesting. Under certain circumstances as set forth in the governing agreements, all shares of restricted common stock granted to reporting person may be subject to accelerated vesting.

3. Subject to certain conditions, this option grant becomes vested and exercisable at a rate of one-third on 10/20/2008, one-third on 10/20/2009, and one-third on 10/20/2010. All unvested stock options under this grant immediately vest and become exercisable in the event of a change in control of the Company (as defined in the governing agreement).

4. Subject to certain conditions, this option grant becomes vested and exercisable at the rate of one-third on 11/30/2007, one-third on 11/30/2008, and one-third on 11/30/2009. All unvested stock options under this grant immediately vest and become exercisable in the event of a change in control of the Company (as defined in the governing agreement).

5. This option grant is fully vested.

6. The reported incentive bonus units will become vested with respect to 25% of the total number of incentive bonus units granted on May 15 of each of the calendar years 2007, 2008, 2009 and 2010, and will entitle the reporting person to receive a distribution of cash equal in value to the amount by which the average of the per share closing prices of the Company's common stock over a specified period of time exceeds the base value of $20.00 (which is subject to adjustment in the event of a change in the Company's capitalization). In the event the formula decribed above results in no payment to the reporting person on a vesting date, then the incentive bonus units vesting on such date will be forfeited without consideration. On May 15, 2007 and on May 15, 2008, the formula described above resulted in no payment to the reporting person. Accordingly, the reporting person forfeited 25% of his total incentive bonus units on each of May 15, 2007 and May 15, 2008.
