NEON will receive no part of the proceeds of the sales. NEON originally issued all of the Shares in connection with the acquisitions of PaperFree Systems, Inc., located in Vienna, Virginia ("PaperFree") and SECCO Software-Engineering, Computing and Consulting GmbH, located in Frankfurt, Germany ("SECCO"). The "Selling Stockholders" section of the Prospectus is hereby supplemented to identify the holders of shares distributed in connection with the "make whole" provisions described in footnote 1 to the Selling Stockholder table of the May 22, 2000 Prospectus. The Prospectus Supplement should be read in conjunction with the Prospectus, and this Prospectus Supplement is qualified by reference to the Prospectus except to the extent that the information herein contained supersedes the information contained in the Prospectus. Capitalized terms used in this Prospectus Summary and not otherwise defined herein have the meanings specified in the Prospectus. SELLING STOCKHOLDERS The following amended table sets forth the number of shares owned by each of the Selling Stockholders who were formerly stockholders of the PaperFree or SECCO, and who received additional shares of NEON Common Stock in connection with NEON's acquisition of PaperFree and SECCO, respectively, as set forth in footnote 1 to the Prospectus. The table below sets forth, as of the date of this Prospectus Supplement, the name of such Selling Stockholders, the number of shares beneficially owned by them, and the number of shares which may be sold by them pursuant to the Prospectus as of the date of this Prospectus Supplement. None of such Selling Stockholders has had a material relationship with NEON within the past three years other than as described below or as a result of the ownership of the shares or other securities of NEON. None of such Selling Stockholders holds a number of shares that exceeds 1% of NEON's outstanding capitalization. No estimate can be given as to the amount of shares that will be held by such Selling Stockholders after completion of this offering because such Selling Stockholders may offer all or some of the shares and because there currently are no agreements, arrangements or understandings with respect to the sale of any of the shares. The shares offered by this Prospectus may be offered 2 from time to time by the Selling Stockholder named below. The Company may amend or supplement the Prospectus and this Prospectus Supplement from time to time to update the disclosure set forth therein and herein.

A number of shares which are, in the Company's best estimation, equivalent to these shares have been included in this registration statement, but they are not included in either column of the table. We intend to file a prospectus supplement to reflect any change in the number of shares offered by the individual Selling Stockholders as a result of these provisions. (2) Does not include an aggregate of 65,473 shares of common stock beneficially owned by the Selling Stockholders that have been deposited in escrow to secure the indemnification obligations of the Selling Stockholders. A number of shares equivalent to these escrow shares have been included in this registration statement, but they are not included in this column of the table. We intend to file a prospectus supplement to reflect any change in the number of shares offered by the individual selling stockholders as a result of the expiration of the escrow.
