Arbitron Inc. Chairman and Chief Executive Officer Adopts 10b5-1 Trading Plan

Arbitron Inc. (NYSE: ARB) announced today that Stephen B. Morris, chairman, president and chief executive officer, has established a new stock trading plan in accordance with guidelines specified under Rule 10b5-1 of the Securities Exchange Act of 1934. Mr. Morris is establishing this plan to diversify his investment portfolio in an orderly, prearranged manner and to facilitate payment of taxes. This new plan, which goes into effect on March 4, 2008, will replace an existing stock trading plan, which expired by its terms on November 1, 2007. Under the terms of the new plan, Mr. Morris will systematically exercise employee stock options and sell up to 90,382 shares of Arbitron stock over a period of 12 months, which a broker is authorized to execute at monthly intervals beginning in April 2008. These employee stock options are from grants that will expire on October 20, 2009 and August 19, 2014. Mr. Morris is in full compliance with the company's stock ownership guidelines and his current level of ownership of common stock will not be affected by this plan. This plan is scheduled to terminate on the earliest to occur of March 31, 2009, or the sale of 90,382 shares. Rule 10b5-1 permits officers and directors of public companies to adopt predetermined plans for selling specified amounts of stock. The plans may be entered into only when the director or officer is not in possession of material, non-public information, and may be used to gradually diversify investment portfolios over a period of time. The plans establish pre-determined trading parameters that do not permit the person adopting the plan to exercise any subsequent influence over how, when or whether to effect trades. Transactions under this plan, and all trades for directors and executive officers of Arbitron Inc., will be disclosed publicly through Form 144 and Form 4 filings as required by the Securities and Exchange Commission.
