NASDAQ Notifies Radio One, Inc. Class A Shares Fall Below Minimum Market Value

Radio One, Inc. (NASDAQ:ROIAK and ROIA), announced today that on May 21, 2008, the Company received a letter from The Nasdaq Stock Market notifying the Company that for the last 30 consecutive trading days, the Company’s Class A Common Shares have not maintained a minimum market value of publicly held shares of $5,000,000 as required for continued inclusion by Marketplace Rules. The notification does not affect the Class D Common Shares which represent over 95 percent of the Company’s outstanding public float. In accordance with Marketplace Rules, the Company will be provided 90 calendar days, or until August 19, 2008, to regain compliance with respect to the Class A Shares. If, at anytime before August 19, 2008, the minimum market value of the Company’s Class A Common Stock is $5,000,000 or greater for a minimum of 10 consecutive trading days, NASDAQ will provide written notification that the Company complies with the Rules. If compliance with this Rule cannot be demonstrated by August 19, 2008, NASDAQ will provide written notification that the Company’s securities will be delisted. At that time, the Company may appeal NASDAQ’s determination to a listing qualifications panel. "This is a result of the gradual migration of our Class A shareholders into our Class D Shares,” said Alfred C. Liggins, III, Chief Executive Officer of Radio One. "Since January 2005, we have seen shareholders convert almost 18 million shares of Class A Stock into Class D Stock given the conversion rights that the Class A Shares carry and the greater liquidity in the Class D Shares. Regardless, our focus is on maximizing long-term value and maintaining the liquidity of all of our securities.” The Company’s Class A Shares maintain their right to convert into Class D Shares.
