— Westwood One’s Directors Approve Agreements and Recommend
Shareholders Vote For Agreements —

New York, NY — October 2, 2007 — Westwood One, Inc. (NYSE: WON) announced today that it has entered into binding agreements (subject to shareholder ratification) with CBS Radio, Inc. documenting a new long-term arrangement through March 2017. Westwood One’s Management Agreement, Representation Agreement and other related programming agreements and distribution arrangements with CBS Radio were scheduled to expire on March 31, 2009.

David Dennis, Chair of the Company’s Strategic Review Committee, which led the negotiation process with CBS Radio, stated: “We are pleased to announce the execution of this new arrangement with CBS Radio. We believe the proposed transaction provides several benefits to the Company and its shareholders, including continued long-term distribution of Westwood One programming and products to major-market radio stations, compensation tied to delivery of audience and an extension of non-competition provisions through March 2010.” Gary Yusko, Westwood One’s Chief Financial Officer, added: “With the negotiation process behind us, we can move forward with solidifying our financial structure and exploring initiatives to enhance shareholder value.”

The Westwood One Board of Directors has approved this new arrangement and recommended it to Company shareholders for approval. The Company is presently working on a preliminary proxy statement which it anticipates filing with the SEC by November 10, 2007, and intends to submit definitive proxy materials to its shareholders at an annual meeting of shareholders to be held early in the first quarter of 2008 at which time the proposed agreements will be voted on by Company shareholders.

“We’re pleased to begin a new chapter in CBS Radio’s long-standing relationship with Westwood One,” said Dan Mason, President and Chief Executive Officer of CBS Radio. “From broadcasting local traffic across our owned stations, to CBS Radio News across the Westwood One network, CBS and Westwood create a content and distribution team that is unparalleled in the industry.”

The new agreements include the following highlights which will become effective upon ratification by shareholders and satisfaction of other closing conditions. A more complete description of the material terms of the arrangement will be included in a Form 8-K to be filed with SEC within the next few days. A detailed description of the entire arrangement will be included in the Company’s proxy statement.

• Distribution: Under the terms of the agreements, the radio stations owned by CBS Radio will broadcast Westwood One commercial inventory, including that of the Network and Metro Networks divisions, through March 31, 2017 in exchange for certain programming and/or cash compensation. Any cash compensation to be paid to CBS’s radio stations will be tied to audience delivery (with respect to Network Inventory) and/or commercial inventory clearances (with respect to Network and Metro inventory). CBS Radio will receive cash incentives if the stations attain a high level of performance, and cash penalties will apply if a radio station’s performance falls below certain prescribed levels.

• Programming: The News Programming Agreement, which provides Westwood One with the exclusive national radio syndication rights to CBS Radio News, will continue through March 31, 2017.

• Management: The Management Agreement and Representation Agreement between Westwood One and CBS Radio will terminate. Westwood One will manage its business directly and separately from CBS Radio, and employ all of its officers. Employees of CBS Radio will resign from the Company’s Board. The provisions of the Management Agreement providing Westwood with: (i) a right of first refusal to syndicate CBS Radio programming will continue through March 2017 and (ii) certain non-competition and non-solicitation rights will continue through March 31, 2010 and 2012, respectively. In addition, as part of the termination of the historical arrangements between the companies, Westwood One and CBS Radio are releasing certain claims they may have against each other.

• Equity/Securities: Westwood One will retire the existing 3,000,000 warrants held by CBS Radio in Westwood One. CBS Radio has agreed to a standstill on the sale of its Company common stock until December 31, 2007.

The foregoing arrangement is subject to the approval of Westwood One shareholders, which will require the affirmative vote of shareholders owning a majority of the shares of common stock and Class B stock, voting together (not including shares owned by CBS Radio or its affiliates), represented in person or by proxy at the shareholders’ meeting. Further conditions to closing include the Company having adequate financing to conduct its business operations and the Company paying all amounts owed to CBS prior to consummating the transaction.

UBS Investment Bank and Moelis Advisors, a division of Mercanti Securities, LLC, advised in connection with the renegotiation of the CBS agreement and are continuing to advise the Strategic Review Committee on strategic opportunities. In addition, the independent directors have engaged Korn Ferry to conduct a search for the Company’s next CEO. As previously announced by the Company, Peter Kosann, a CBS employee, will step down upon the completion of the transaction with CBS Radio.
