Business Wire, May 12, 2008

REDWOOD CITY, Calif. -- Openwave Systems Inc. (Nasdaq:OPWV), one of the world's leading software innovators enabling revenue-generating personalized services which converge the mobile and broadband experience, today announced that it will delay the filing of its quarterly report on Form 10-Q for the three months ended March 31, 2008 pending the conclusion of an internal investigation being conducted under the direction of the Audit Committee of the Board of Directors, with the assistance of independent counsel, into allegations made by an employee relating to attempts by certain members of senior management to manage financial results. To date, the investigation has not reached any conclusion that the company's previously issued financial statements and earnings releases were materially misleading.

"The Company and its Board of Directors take these matters very seriously and accordingly the Company's management is cooperating fully," said Bruce Coleman, Interim Chief Executive Officer of the Company.

Although the Company is currently unable to predict the timing of the conclusion of the internal investigation, the Company will not be able to file its Quarterly Report on Form 10-Q by its prescribed due date, including the five-day extension of the filing deadline permitted under Rule 12b-25. The Company intends to file its Quarterly Report on Form 10-Q for the quarter ended March 31, 2008 as soon as practicable following the conclusion of the internal investigation.
