ITEM 3.01.                       Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing

On May 21, 2008, Radio One, Inc. (the "Company") received a letter (the “Notification”) from The NASDAQ Stock Market (“NASDAQ”) notifying the Company that for the last 30 consecutive trading days, the Company’s Class A common shares (the “Class A Shares”) have not maintained a minimum market value of publicly held shares (“MVPHS”) of $5,000,000 as required for continued inclusion by Marketplace Rule 4450(a)(2) (the “Rule”).  Therefore, in accordance with Marketplace Rule 4450(e)(1), the Company will be provided 90 calendar days, or until August 19, 2008, to regain compliance.  If, at anytime before August 19, 2008, the MVPHS 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 Rule.  If compliance with this Rule cannot be demonstrated by August 19, 2008, NASDAQ will provide written notification that the Class A Shares will be delisted.  At that time, the Company has the right to appeal NASDAQ’s determination to a listing qualifications panel.

The notification does not affect the Class D Common Shares which represent over 95 percent of the Company’s outstanding public float.  The Company’s Class A Shares maintain their right to convert into Class D Shares.
