Explanation of Responses:

1. In January 2007, the issuer paid a special dividend of $5.40 per share of common stock to all stockholders of record as of the close of business on December 29, 2006. In connection with this special dividend, the issuer's Board of Directors adjusted all options that were awarded, but not exercised, prior to the ex-dividend date for the special dividend to account for the effect of the special dividend. The number of shares subject to each such option was increased and the exercise price correspondingly decreased such that each option had the same fair value to the holder before and after giving effect to the payment of the special dividend. Pursuant to this adjustment the number of shares underlying Mr. Selsam's options increased by 2,364 from 47,058 to 49,422 and the per share exercise price was correspondingly decreased.

2. The options vested in three equal annual installments beginning on January 18, 2002.
