This Prospectus Supplement should be read in conjunction with, may not be delivered or utilized without, and 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 Supplement and not otherwise defined herein have the meanings specified in the Prospectus. SELLING STOCKHOLDERS Recently, XML Fund LLC transferred a total of 35,794, of its shares of the Common Stock to its members, David Pool and David Kenyon. One of such transferees, David Kenyon, was not specifically named in the Prospectus. The following table lists the Selling Stockholder not previously specifically identified in the Prospectus as a Selling Stockholder, and the number of shares such Selling Stockholder beneficially owns and may sell pursuant to the Prospectus from time to time. The information in the table appearing under the heading "Selling Stockholders" in the Prospectus is hereby amended by adding the information below with respect to Mr. Keynon and by substituting the information set forth below in the case of Mr. Pool and the XML Fund LLC: Shares of Common Stock Shares of Common Stock to be Beneficially Beneficially Owned Prior to Owned after Offering(1)(9) Offering(1)(2)(9) ------------------------------- ------------------------- Name of Selling Stockholder Number Percentage Number of Shares of Number Percentage Common Stock Being Offered David Kenyon(9) 243 * 243 0 0 David Pool(3)(4)(5)(9) 171,114 * 171,114 0 0 XML Fund LLC(9) 3,977 * 3,977 0 0 -------------------------- * Less than one percent. (1) Of the total shares of common stock listed as owned by the selling stockholders, a total of 250,000 shares are held in an escrow account to secure indemnification obligations of the former stockholders of DataChannel to us. It is expected that these shares (less any shares that may be distributed from the escrow account to us in satisfaction of indemnification claims) will be released from escrow and distributed to the selling stockholders on December 14, 2002. The number of shares indicated as owned by each selling stockholder includes those shares (representing approximately 10% of the number of shares listed as beneficially owned by each selling stockholder) which such selling stockholder is entitled to received upon distribution of these shares from the escrow account. (2) We do not know when or in what amounts a selling stockholder may offer shares for sale. The selling stockholders might not sell any or all of the shares offered by this prospectus. Because the selling stockholders may offer all or some of the shares pursuant to this offering, and because there are currently no agreements, arrangements or understandings with respect to the sale of any of the shares, we cannot estimate the number of the shares that will be held by the selling stockholder after completion of the offering. However, for purposes of this table, we have assumed that, after completion of the offering, none of the shares covered by this prospectus will be held by the selling stockholders. (3) Employees or former employed of Netegrity and/or DataChannel. (4) Former directors or employees of DataChannel. (5) Excludes 3,977 shares of Netegrity common stock owned by XML Fund, LLC, a Washington limited liability company of which David Pool is the manager and of which he owns a majority of the equity interest. (9) XML Fund, LLC distributed to its members all of the shares of Netegrity common stock owned by XML Fund, LLC which were not held in the escrow account. The remaining 3,977 shares of Netegrity common stock owned by XML Fund, LLC are held in the escrow account. None of the 35,551 or 243 shares of Netegrity common stock distributed to David Pool or David Kenyon, respectively, is held in the escrow account. None of the selling stockholders has held any position or office with, or has otherwise had a material relationship with, us or any of our subsidiaries within the past three years, except that the selling stockholders indicated have been employed by us and/or DataChannel or were members of the DataChannel board of directors. In connection with our acquisition of DataChannel, we entered into employment offer letters with Lucie Fjeldstad, formerly President and Chief Executive Officer of DataChannel, and James Beach, formerly Chief Financial Officer of DataChannel, under which each agreed to perform certain services for us through June 14, 2002.
