(the "Issuer"), as follows: Item 5. Interest in Securities of the Issuer. SAP AG beneficially owns 5,831,481 shares of Common Stock, including 1,749,444 shares of Common Stock that SAP AG acquired upon the termination of the Master Agreement for Securities Loan Transactions dated December 16, 2002 and related Transaction Confirmation dated December 23, 2002 (collectively, the "Agreement") between SAP AG and HSBC Trinkaus and Burkhardt KGaA, a German bank. The Agreement was terminated by SAP AG, effective as of July 18, 2003. The 5,831,481 shares beneficially owned by SAP AG represent approximately 19.92% of the Issuer's shares of Common Stock based on 29,270,247 shares of Common Stock outstanding as of May 12, 2003, as reported by the Issuer in its Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2003. SAP AG has sole voting and dispositive power with respect to 5,831,481 shares of Common Stock of the Issuer beneficially owned by SAP AG, but these shares are subject in certain respects to limitations under the Standstill Agreement and the Investor Rights Agreement as described in Item 4 of the Schedule 13D.
