(1)	In October 2005, the issuer paid a special dividend of $2.50 per share of common stock to all stockholders of record as of the close of business on September 30, 2005. 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.
(2)	Pursuant to the adjustment described in Footnote 1, the number of shares underlying the options increased by 6,476 from 179,255 to 185,731 and the per share exercise price was correspondingly decreased.
(3)	Pursuant to the adjustment described in Footnote 1, the number of shares underlying the options increased by 36,132 from 1,000,000 to 1,036,132 and the per share exercise price was correspondingly decreased.
(4)	The option vested in five equal annual installments beginning on March 24, 1999.
(5)	The option vested in three equal annual installments beginning on February 02, 2002.
