This Amendment No. 6 (this “Amendment”) amends and supplements the Tender Offer Statement on Schedule TO filed with the Securities and Exchange Commission on May 26, 2010 (as amended or supplemented, the “Schedule TO”) by Sheffield Acquisition Corp., a Delaware corporation (the “Purchaser”) and a wholly-owned subsidiary of SAP America, Inc., a Delaware corporation (“SAP America”) and an indirectly wholly-owned subsidiary of SAP AG, a stock corporation organized under the laws of the Federal Republic of Germany (“SAP AG”). The Schedule TO relates to the offer by the Purchaser to purchase all of the outstanding shares of common stock, par value $0.001 per share (the “Sybase Common Stock”), including the associated rights to purchase shares of Series A Participating Preferred Stock issued pursuant to the Preferred Stock Rights Agreement, dated as of July 31, 2002, as amended, by and between Sybase, Inc., a Delaware corporation (“Sybase”), and American Stock Transfer and Trust Company (together with the Sybase Common Stock, the “Shares”), of Sybase, at a price of $65.00 per Share, net to the holder thereof in cash, without interest and less any required withholding of taxes, upon the terms and subject to the conditions set forth in the offer to purchase, dated May 26, 2010 (as it may be amended or supplemented, the “Offer to Purchase”), and the related letter of transmittal (as it may be amended or supplemented, the “Letter of Transmittal,” and together with the Offer to Purchase, the “Offer”), copies of which were filed with the Schedule TO as Exhibits (a)(1)(A) and (a)(1)(B), respectively. Capitalized terms used and not otherwise defined in this Amendment shall have the meanings assigned to such terms in the Offer to Purchase or in the Schedule TO.

Items 1, 4, 8 and 11

Items 1, 4, 8 and 11 of the Schedule TO are hereby amended and supplemented by adding the following paragraph to the end of each Item:

“The Offer expired at 9:00 p.m., New York City time, on Monday, July 26, 2010. The Offer was not extended. The Depositary has advised SAP America that a total of 80,929,717 Shares were validly tendered and not properly withdrawn upon expiration of the Offer (including 9,293,901 Shares subject to guaranteed delivery procedures). The number of shares validly tendered and not properly withdrawn upon expiration of the Offer represents approximately 92.1% of all outstanding Shares, and approximately 91.8% of Sybase’s voting securities determined on a Fully Diluted Basis. The Purchaser has accepted for payment all Shares that were validly tendered and not properly withdrawn in the Offer.

SAP America and the Purchaser intend to effect a short-form merger as promptly as practicable, without the need for a meeting of Sybase’s shareholders. In the Merger, the Purchaser will be merged with and into Sybase with Sybase continuing as the Surviving Corporation and a wholly-owned subsidiary of SAP America. At the effective time of the Merger, each Share issued and outstanding immediately prior to the effective time of the Merger (other than Shares that are held by Sybase, SAP America or any of their wholly-owned subsidiaries or Shares held by stockholders who properly exercise appraisal rights under the Delaware General Corporation Law) will, by virtue of the Merger and without any action on the part of the holders of the Shares, be converted into the right to receive $65.00 net to the holder in cash, without interest and subject to any required withholding of taxes.

SAP AG issued a press release on Tuesday, July 27, 2010, announcing the completion of the Offer. The full text of the press release is attached hereto as Exhibit (a)(5)(H) and is incorporated herein by reference.”
