SYBASE COMMENCES $300 MILLION MODIFIED DUTCH AUCTION TENDER OFFER

DUBLIN, Calif. — March 10, 2008— Sybase, Inc. (NYSE: SY), a leading provider of enterprise infrastructure and mobile software, today announced it has commenced its previously announced modified Dutch auction tender offer to purchase up to $300 million of its common stock, at a price range of $28 to $30 per share. The number of shares proposed to be purchased in the tender offer represents approximately 11.6% of Sybase’s currently outstanding shares, at the mid-point of the price range.

The tender offer will expire at 5:00 p.m. Eastern Time on Monday, April 7, 2008, unless extended by Sybase. Tenders of Sybase’s common stock must be made prior to the expiration of the tender offer and may be withdrawn at any time prior to the expiration of the tender offer.

The modified Dutch auction will allow stockholders to indicate how many shares and at which price within the company’s specified range they wish to tender. Based on the number of shares tendered and the price specified by the tendering stockholders, the company will determine the lowest price per share within the range that will enable it to purchase up to 10,000,000 shares, or such lesser number of shares as are properly tendered. All shares accepted in the tender offer will be purchased at the same price per share even if the stockholder tendered at a lower price. If the price per share determined in the tender is less than $30, the Company expects to purchase additional

shares such that a total of $300 million is used to purchase the Company’s shares. If stockholders tender more than $300 million worth of shares at or below the determined purchase price per share, Sybase will purchase $300 million of shares, subject to proration.

The tender is subject to conditions and other terms set forth in the tender offer materials that are being distributed to stockholders and filed with the Securities and Exchange Commission (SEC) today.

Stockholders must decide how many shares they will tender, if any, and the price within the specified range at which they will tender their shares for purchase by the Company.
