*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	The award reported herein was part of an award of 5,441 shares of restricted stock awarded on April 21, 2008. The total award vested as to 25% immediately upon the original award date and vested as to the remaining shares at a rate of 25% annually from the original award date. Ms. Moon is now reporting all of the unvested shares, including the 25% that vested as of the event date, since the total shares awarded should have been reported on the original award date. All amounts reported herein reflect the recapitalization of the Company's common stock and the related adjustment of outstanding stock awards, whereby each share of the Company's common stock was converted into 1/12th of a share each of the Company's Class A, B-1, B-2 and B-3 common stock.
(2)	In connection with the vesting of 1,360 shares of deferred stock on April 21, 2010, 440 shares were delivered to the Company to satisfy tax withholding obligations, in accordance with the Company's 2007 Omnibus Incentive Plan.
