( 2)	These deferred stock units convert on a one for one basis.
( 3)	Includes an aggregate of 899.4157 deferred stock units acquired through dividend reinvestment. Pursuant to the Merger Agreement, the deferred stock units were cancelled in exchange for a cash payment equal to $48.00 per share.
( 4)	These deferred stock units vested in full on the first anniversary from the date of grant and are payable no sooner than 30 days after the reporting person ceases to be a director of Arbitron Inc.
( 5)	Pursuant to the Merger Agreement, these options, which provided for vesting in three equal annual installments beginning on the first anniversary of the date of grant for each such option, were canceled in exchange for a cash payment representing (1) the difference between $48.00 per share and the exercise price of each such option and (2) the "Black-Scholes Termination Value," which is a term defined in the option award agreements to mean the excess, if any, of the Black-Scholes value of the option determined at the time of the transaction using assumptions set forth in the option award agreements, over the in-the-money value of the option calculated in accordance with (1) above.
