(1) These shares were withheld by the issuer upon the vesting of a restricted stock award to satisfy Mr. Darby'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.
(2) The shares are represented by units held in a unitized stock fund through the Issuer's 401(k) Retirement Plan and Trust. The unitized stock fund of the Issuer's 401(k) Retirement Plan and Trust consists of cash and Common Stock in amounts that vary from time to time. As of March 31, 2012, the reporting person had 3,071 units in the Issuer's 401(k) Retirement Plan and Trust, which units consisted of 2,454 shares of Common Stock.
(3) The option, representing a right to purchase a total of 10,000 shares, becomes exercisable in two equal installments of 5,000. The first such installment occurred on December 14, 2011, which was the fourth anniversary of the date on which the option was granted, and the second such installment occurs on December 14, 2012, which is the fifth anniversary of the date on which the option was granted.
