Explanation of Responses:

The Reporting Person's deemed purchase of the Issuer's Common Stock reported herein was matchable under Section 16(b) of the Securities Exchange Act of 1934, to the extent of 5,000 shares with the Reporting Person's sales of the Issuer's Common Stock at a weighted average price of $23.7536 per share on November 23, 2010. The Reporting Person has paid $6,268 to the Issuer, representing the deemed profit realized in connection with the short-swing transaction as calculated pursuant to Section 16(b). The Reporting Person may owe additional disgorgement to the Issuer in the event of a future sale of the Issuer's Common Stock within six months of December 14, 2010 on the incremental amount, if any, between the future sale price and the prices used to calculate the disgorgement disclosed above, and only on 5,000 shares.

2. The sale reported in this Form 4 was effected pursuant to a Rule 10b5-1 trading plan adopted by the Reporting Person on June 28, 2010.

3. Sale prices range from $22.23 per share to $22.83 per share. Sale price listed represents the weighted average sale price of all 50,000 shares sold.

4. Represents a non-market transfer of such shares by a co-signor on the Reporting Person's joint account to the co-signor's sole account.

5. 25% of the shares subject to the option vested on September 1, 2006, and the remaining shares vested monthly thereafter, such that 100% of the shares subject to the option became fully vested on September 1, 2009.
