IMPORTANT REMINDER CONCERNING THE PROPOSED MERGER OF JDN REALTY
CORPORATION AND DEVELOPERS DIVERSIFIED REALTY CORPORATION

Dear JDN Realty Corporation Shareholder:

     We have not yet received your proxy on the proposed merger between JDN Realty Corporation and Developers Diversified Realty Corporation (“DDR”). No matter how many or how few shares you own, your vote is important.

     JDN Realty is holding a Special Meeting of its shareholders on Thursday, March 13, 2003. At this meeting, you will be asked to approve the merger agreement and the merger. If the proposed merger is completed, each outstanding share of JDN Realty common stock will be converted into 0.518 of a DDR common share. For reasons explained in the Proxy Statement previously sent to you, the Board of Directors encourages you to vote FOR this proposal.

     The Special Meeting originally scheduled for January 29, 2003 was adjourned to March 13, 2003, and the record date was reset from December 2, 2002 to February 12, 2003. EVEN IF YOU SUBMITTED A PROXY CARD FOR THE ORIGINAL MEETING, WE REQUEST THAT YOU TAKE A MOMENT TO RETURN THE ENCLOSED PROXY CARD FOR THE ADJOURNMENT.

     Since consummation of the merger requires the approval of at least two-thirds of JDN Realty’s outstanding shares of common stock, a failure to vote will have the same effect as a vote against the merger.

     Please take the time today to return the enclosed proxy card in the envelope provided.

     I cannot overemphasize the importance of your vote. If you need an additional copy of the Proxy Statement, have questions or need assistance voting your shares, please call Georgeson Shareholder, which is assisting us with the solicitation of proxies, at (212) 440-9800 or Toll-free at (866) 870-4476.

     Your prompt attention to this matter is greatly appreciated.

     
    Sincerely,
     
     
    -s- Craig Macnab
    Craig Macnab
President and Chief Executive Officer
