SAP Commences Tender Offer for All Outstanding Shares of Sybase, Inc.

WALLDORF, Germany — May 26, 2010 — SAP today announced that its indirectly wholly-owned subsidiary, Sheffield Acquisition Corp., has commenced its cash tender offer for all outstanding shares of common stock of Sybase, Inc. at a price of $65.00 per share. The tender offer is being made pursuant to an Offer to Purchase, dated May 26, 2010, and in connection with the Agreement and Plan of Merger, dated May 12, 2010, by and among SAP America, Inc., Sheffield Acquisition Corp., and Sybase, which SAP and Sybase announced on May 12, 2010.

The board of directors of Sybase has unanimously determined that the offer and the other transactions contemplated by the merger agreement are fair to and in the best interests of Sybase’s stockholders. The Sybase board also approved the merger agreement, declared the merger agreement advisable and recommended that holders of shares of Sybase common stock tender their shares in the offer and adopt the merger agreement, if adoption by Sybase’s stockholders is required by applicable law.

The tender offer is scheduled to expire at 9:00 p.m., Eastern Time, on Thursday, July 1, 2010, unless the tender offer is extended.

There is no financing condition to the tender offer. The consummation of the tender offer is conditioned on the tender of a majority of the outstanding shares of Sybase’s common stock on a fully diluted basis, as well as receipt of antitrust clearance, and other conditions that are specified in the offer documents. Following completion of the tender offer and, if required, receipt of stockholder approval, SAP expects to consummate a merger in which remaining Sybase stockholders will receive the same cash price per share as paid in the tender offer. Following the merger, Sybase will become an indirectly wholly-owned subsidiary of SAP.
