Explanation of Responses:

1. Includes 25,000 Financial Performance-Based Restricted Stock (Class A Shares) ("FPB Restricted Stock") of the Issuer, awarded February 28, 2006 and 14,006 FPB Restricted Stock awarded March 20, 2007. 12,500 Shares of the February 2006 grant were deemed to have fully vested on March 15, 2007. The remaining portion may vest in 2008 and/or 2009 if the Issuer achieves specified financial performance targets in 2007 - 2008, and is dependent upon continued employment. With respect to the March 2007 grant, the performance-based vesting period extends over 2007, 2008, 2009 and 2010, and is also based on financial targets and continued employment. Such financial targets are set forth in a "Financial Performance-Based Restricted Stock Agreement", a form of which was filed by the Issuer as an exhibit to a Form 8-K filed with the SEC on March 2, 2006.

2. Stock Appreciation Rights (previously granted on November 17, 2004) vest 1/3 on each anniversary of the grant date, expire four years from the grant date, and may be settled in cash or stock at the discretion of the Issuer.
