EXPLANATORY NOTE

     On February 7, 2001, the Company acquired all of the outstanding capital stock of Corsair Communications, Inc. (“Corsair”) in exchange for capital stock of the Company as the result of a merger between Corsair and a wholly owned subsidiary of the Company. In connection with the merger, all of the options previously granted under Corsair’s 1997 Stock Incentive Plan (the “Corsair Plan”) and the Subscriber Computing, Inc. 1997 Incentive Stock Option, Nonqualified Stock Option and Restricted Stock Purchase Plan (the “Subscriber Computing Plan”), which prior to the merger were (when vested) exercisable to purchase Corsair common stock, were assumed by the Company and are now (when vested) exercisable to purchase Company Common Stock.

     Authorize.Net Holdings, Inc., a Delaware corporation (the “Company”), is filing this Post-Effective Amendment No.1 to the Registration Statement on Form S-8 (File No. 333-56772) filed on March 9, 2001, pertaining to the common stock of the Company, par value $0.001 per share (the “Common Stock”), offered under the Corsair Plan and the Subscriber Computing Plan.

     On November 1, 2007, pursuant to an Agreement and Plan of Reorganization (the “Merger Agreement”), dated as of June 17, 2007, by and among the Company, CyberSource Corporation (“CyberSource”), Congress Acquisition-Sub, Inc. and Congress Acquisition Sub 1, LLC, the Company became a wholly-owned subsidiary of CyberSource. As provided in the Merger Agreement, each share of Common Stock of the Company was converted, directly or indirectly, into the right to receive (a) 1.1611 shares of CyberSource common stock and (b) a pro rata share of $125 million in the form of a cash payment. Pursuant to the Merger Agreement, the Company and CyberSource have taken such actions as are necessary such that the Company’s Common Stock is no longer issuable under the Corsair Plan and the Subscriber Computing Plan.

     The Company hereby removes and withdraws from registration all securities registered pursuant to the Registration Statements that remain unissued.
