REDWOOD CITY, Calif. – August 31, 2006 – Openwave Systems Inc. (Nasdaq: OPWV), the leading provider of open software products and services for the communications industry, today announced that the company will streamline its management team with the elimination of four senior management level positions and reduce its worldwide staff by approximately 65 people.

“By taking these steps we will reduce the numbers of layers of management between our customers and our field and product organizations,” said David Peterschmidt, CEO of Openwave. “This will enhance our capability to continue to provide our customers with the products and services that they require in a timelier manner.”

The senior management level positions affected include the chief marketing officer, chief administrative officer, chief operating officer and chief corporate strategy and business development officer. The duties and responsibilities of the senior management positions will be assumed by existing senior management in Openwave’s field and product organizations.
