Estimated Revenues of $245 - $250 Million; Operating Profit

Sybase announced today that revenues for the fourth quarter
ending December 31, 1997 are currently expected to be in the
range of $245 million to $250 million. The company expects
to report an operating profit before taxes. The company also
expects earnings per share to range from a loss of ($0.07)
to a profit of $0.02 per share.

These estimated results are preliminary, subject to the
company closing its books and the company's management and
independent auditors completing their customary quarterly
review and annual audit procedures.

The estimated results in this announcement constitute
forward looking statements. Actual results for the Company's
fourth quarter and for the 1997 fiscal year could materially
differ from those estimated depending on a number of
factors, including whether all orders included in estimated
revenues meet the company's revenue recognition
requirements, the adequacy of estimated expense accruals and
reserves, the adequacy of the estimated tax provided for the
fourth quarter and fiscal year and adjustments arising from
the customary annual audit by management and the company's
independent auditors.
