DEREGISTRATION OF SHARES

On June 14, 2001, the Board of Directors of the Registrant resolved to approve and adopt the Openwave Systems Inc. 2001 Stock Compensation Plan (the "2001 Plan") and resolved further to merge and subsume the AtMobile.com, Inc. Amended and Restated 1997 Stock Option Plan and the Software.com, Inc. 2000 Nonstatutory Stock Option Plan (together, the "Predecessor Plans") into the 2001 Plan. This Post-Effective Amendment No. 3 to the Registrant's Registration Statement No. 333-44926 on Form S-8 POS filed on November 20, 2000 (the "Registration Statement") is filed to deregister 119,425 shares previously registered that remain available for future grant under the AtMobile.com, Inc. Amended and Restated 1997 Stock Option Plan and 2,643,158 shares previously registered that remain available for future grant under the Software.com, Inc. 2000 Nonstatutory Stock Option Plan. The 2,762,583 shares deregistered by this Post-Effective Amendment No. 3 will be registered, by a subsequently filed registration statement on Form S-8 for the 2001 Plan, and the associated registration fee paid by the Registrant to register shares issuable under the Predecessor Plans on the Registration Statement will be carried forward and applied to the registration fee necessary to register shares issuable under the Registrant's 2001 Plan. Please note, however, that 170,936 shares remain subject to outstanding options previously granted under the Predecessor Plans. Accordingly, the Registration Statement will remain in effect to cover the potential exercise of such outstanding options.
