Explanation of Responses:
1. The Common Stock reported in this item was issued upon the settlement of a portion of a grant of Salary Stock Units ("SSUs) issued on September 30, 2010 pursuant to the Company's Salary Stock Plan (the "GMSSP") and vested upon grant. The portion of this award currently payable was settled on September 30, 2011 in shares of the Company's Common Stock, less a portion withheld for taxes.
2. On September 30, 2010 the employee received a grant of 8,183 SSUs, of which 2,728 SSUs were scheduled to be payable on September 30, 2011. On November 1, 2010 the Company amended its certificate of incorporation to effect a stock split in which each issued and outstanding share of Common Stock was converted into three shares of Common Stock. Pursuant to the terms of the GMSSP, each issued and outstanding SSUs was automatically converted into three SSUs, so that the employee was credited with a total of 24,549 SSUs granted on September 30, 2010, of which 8,184 SSUs became payable on September 30, 2011.
3. The SSUs do not have an expiration or exercise date or carry a conversion or exercise price. Each SSU is the economic equivalent of one share of Common Stock. Under the GMSSP, the Fair Market Value of the Common Stock is the average of the high and low trading prices for the Common Stock as reported on the New York Stock Exchange, on which the Common Stock is listed, on the date of the transaction, which was $20.30.
4. The SSUs reported in this item were granted on September 30, 2011 pursuant to the GMSSP and were fully vested upon grant. The SSUs will be delivered in the form of shares of Common Stock in three equal, annual installments beginning on September 30, 2012.
