Explanation of Responses:

Id	Content
F1	The price represents the closing price of the issuer's Class A common stock as of May 9, 2023, the vesting date.
F2	This amount includes (a) Class A common stock attributable to vested restricted stock units that were awarded under the amended 2007 Stock Incentive Plan ("Plan") and (b) unvested restricted stock units that were awarded under the Plan.

Remarks:

This amendment corrects the originally reported number of shares withheld to cover income taxes as a result of the May 9, 2023 vesting under the Plan. The previously reported amount was inadvertently understated by 781 shares.
