Concurrent subsequently filed Pre-Effective Amendment No. 1 to the Registration Statement on July 16, 2001. The Commission declared the Registration Statement effective on July 19, 2001. In accordance with the undertaking contained in Part II, Item 17(a)(3) of the Registration Statement pursuant to Item 512(a)(3) of Regulation S-K, Concurrent files this post-effective amendment to remove from registration all of the shares which remain unsold under the registration statement as of the date hereof. Concurrent is also deregistering all shares to be sold by any purchaser because its obligation to maintain the effectiveness of the Registration Statement with respect to such shares pursuant to the terms of the purchase agreement by and between Concurrent and purchasers dated as of May 15, 2001 has expired. Accordingly, Concurrent files this Post-Effective Amendment No. 1 to the Registration Statement on Form S-3 to deregister 5,400,000 shares of its common stock covered by the Registration Statement that remain unsold as of the date hereof. SIGNATURES Pursuant to the requirements of the Securities Act of 1933, as amended, and Rule 478(a)(4) thereunder, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Post-Effective Amendment No. 1 to the Registration Statement on Form S-3 to be signed on its behalf by the undersigned, thereunto duly authorized, in the city of Duluth, state of Georgia, on October 10, 2003.
