     software for wireline and wireless service providers, today announced
     they will merge to create a global powerhouse that will provide a
     broad range of carrier-class software to wireless and wireline

     Donald J. Listwin as President and Chief Executive Officer, Alain
     Rossmann as Executive Vice President and Chairman of the Board of
     Directors, and John L. MacFarlane as Executive Vice President.

     Under the terms of the definitive merger agreement unanimously
     approved by the Boards of Directors of both companies, shareholders of

     the combined company. Each Software.com shareholder will be entitled

     Software.com. The merger is expected to be accounted for as a pooling
     of interests and is intended to be tax-free to shareholders of both
     companies.

     The merged company will be the premier provider of highly scalable
     infrastructure and application software enabling the delivery of
     email, voicemail, unified messaging, directory, and wireless Internet

     Telefonica, Deutsche Telekom, Mannesmann, and BellSouth. On a pro

     trailing twelve-month revenues of over $146 million, $94 million of
     deferred revenue and cash, cash equivalents and short term investments
     position of over $500 million, creating a powerful platform for
     further growth.

     Donald J. Listwin, who will be President and Chief Executive Officer,
     will join the merged company from Cisco Systems, where he has led
     service provider and consumer lines of business and has been
     responsible for developing Cisco's Internet technology and services
     for telecommunications companies. Alain Rossmann, Chairman and Chief
     Executive Officer of Phone.com, will be Executive Vice President and
     Chairman of the Board of Directors of the combined company. John L.
     MacFarlane, Chief Executive Officer of Software.com, will serve as
     Executive Vice President of the combined company, and Alan J. Black,
     Chief Financial Officer of Phone.com, will be Chief Financial Officer
     of the merged company. The Board of Directors of the merged company
     will consist of Listwin, Rossmann, MacFarlane, Reed E. Hundt, Senior
     Advisor at McKinsey & Company, Inc. and former Chairman of the Federal
     Communications Commission, Bernard Puckett, former Senior Vice
     President of IBM Corporation, and Roger Evans, General Partner of
     Greylock Limited Partners. The Company will be headquartered in
     Redwood City, California.

     "I am thrilled by the opportunity to join forces with Alain and John
     to lead this powerful combined company," said Donald J. Listwin. "This
     strategic merger brings together two dynamic and innovative companies
     with tremendous track records for providing reliable, highly-scalable
     infrastructure software to communication providers worldwide.
     Together, Phone.com and Software.com create a powerfully positioned
     global software company poised to drive and benefit from the
     unification of service offerings by IP-based communications service
     providers."

     "We are extremely excited to be joining forces with Software.com in
     this compelling strategic combination and to have Don join us at the
     merged company," said Alain Rossmann. "Don brings a tremendous track
     record for driving growth at Cisco and more than 20 years of
     experience in the networking industry. With his vision and experience,
     Don is the ideal person to grow and expand the business of the merged
     company. The merged company will be strongly positioned to capitalize
     on the explosive growth of the wireless Internet."

     "With highly complementary customers, product lines and business
     models, we will leverage significant cross-sell and up-sell
     opportunities over a broad portfolio of software products, including
     unified messaging, mobile mail, directory services, wireless Internet
     access gateways, voice processing, synchronization and instant
     messaging," said John L. MacFarlane. "Our customers will benefit from
     the combined company's IP-based infrastructure, unified platform and
     its unparalleled ability to operate across all standards.
     Additionally, by bringing together the industry's top talent under one
     roof, we will have an unmatched ability to innovate and bring new
     products to market."

     "BT is leading the unification of communication services. The combined
     company is uniquely positioned to provide the products, applications
     and services to capture this new market," said Kent Thexton, President
     of BT Global Mobile Internet. "We do business with each of these
     companies today. We look forward to working with the merged company to
     build the future of communication services."

     Mr. Tadashi Onodera, Executive Vice President of DDI Corporation,
     stated, "Japan's wireless Internet market is the fastest growing in
     the world. The merged company's unique ability to provide
     carrier-class, highly scalable software is instrumental to succeeding
     in this market."

     The transaction is expected to close by calendar year-end 2000 subject
     to approval of Phone.com and Software.com shareholders and customary
     closing conditions including obtaining necessary regulatory approvals.
     The name of the combined company will be announced at that time.

     In connection with approving the transaction, the Board of Directors
     of each company also adopted a Stockholder Rights Plan in which rights
     will be distributed as a dividend at the rate of one Right for each
     share of common stock of each company held by stockholders of record
     as of the close of business on August 18, 2000, with respect to
     Phone.com and August 24, 2000 with respect to Software.com. Under the
     Stockholder Rights Plan adopted by each company, the Rights generally
     will be exercisable only if a person or group acquires beneficial
     ownership of 15 percent or more of the company's common stock or
     commences a tender or exchange offer upon consummation of which such
     person or group would beneficially own 15 percent or more of the
     company's common stock.
