Suite 201
Minneapolis, Minnesota 55419-4841

Dear Lawrence,

Please accept this letter as my formal resignation as a board of director of Arbitron effective immediately. Due to the upcoming ownership change of my company it would be a conflict of interest for me to remain on the board.

I wish you and the company much continued success.

Sincerely,

/s/ Erica Farber
