                        OPENWAVE SYSTEMS INC. ANNOUNCES
                          PRICING OF PRIVATE OFFERING
                       OF CONVERTIBLE SUBORDINATED NOTES


REDWOOD CITY, CALIF. - SEPTEMBER 4, 2003 - Openwave Systems Inc. (Nasdaq:
OPWV) today announced the pricing of a private offering of $135,000,000 of its
2.75% convertible subordinated notes due 2008. The offering has been made only
to qualified institutional buyers in accordance with Rule 144A under the
Securities Act of 1933. Openwave has granted the initial purchaser a 30-day
option to purchase up to an additional $15,000,000 of notes. The offering is
expected to close September 9, 2003, subject to customary closing conditions.

Each note will be convertible at any time at the holder's option at a
conversion price of $6.13 per share, which is equal to a conversion rate of
163.1321 shares per $1,000 principal amount of notes, subject to adjustment in
certain circumstances. Openwave expects to use approximately $11 million of
the net proceeds to purchase a portfolio of U.S. government securities that
will be pledged to secure the payment of the first six scheduled interest
payments on the notes. Openwave intends to use the remaining net proceeds from
the offering for additional working capital and other general corporate
purposes, including potential acquisitions or strategic investments. Openwave
has no specific agreements or commitments, and is not currently engaged in any
negotiations, for any material acquisitions or strategic investments.

Each holder of the notes will have the right to require Openwave to repurchase
its notes upon the occurrence of specified change in control events. In
addition, Openwave will have the right to redeem the notes for cash after a
specified date in 2006 if the price of Openwave's common stock exceeds a
specified threshold.

The notes and the shares of common stock issuable upon conversion of the notes
have not been registered under the Securities Act or any other securities
laws. Unless they are registered, the notes and the shares of common stock
issuable upon conversion of the notes may be offered and sold only in
transactions that are exempt from registration under the Securities Act and
any other applicable securities laws.
