Explanation of Responses:
1. The Form 4, as originally filed, incorrectly reported the Transaction Date as 5/23/2012. The Form 4, as amended by this Form 4/A, correctly reports the Transaction Date as 5/22/2012.
2. This option and the option exercised on May 24, 2012 (reported on the Form 4, as originally filed) were exercised pursuant to a Rule 10b5-1 Trading Plan adopted by Mr. Beretta on May 4, 2012.
3. This transaction was erroneously omitted from the reporting person's Form 4 as originially filed.
4. These shares were withheld by the issuer upon the exercise of an employee stock option to satisfy Mr. Beretta's tax withholding obligations. Such withholding is treated as a disposition of securities under Section 16 of the Securities Exchange Act of 1934, as amended.
5. The option, representing the right to purchase a total of 100,000 shares, became exercisable in five equal annual installments beginning on February 2, 2005.
