LUCENT TECHNOLOGIES TO ACQUIRE MOSAIX, A GLOBAL PROVIDER OF CUSTOMER
RELATIONSHIP MANAGEMENT AND CALL CENTER SOFTWARE AND SYSTEMS

For Immediate release:  Monday, April 5, 1999

        MURRAY HILL, N.J. - To expand its call center product portfolio and step
into the fast-growing area of customer relationship management solutions, Lucent
Technologies (NYSE: LU) today announced it has agreed to acquire Mosaix (Nasdaq:
MOSX), a Redmond, Washington-based provider of award-winning software that links
companies' front and back offices and helps them deliver more responsive and
efficient customer service.

        Under terms of the merger agreement, each share of Mosaix will be
converted into 0.1927 shares of Lucent -- $10.77 per Mosaix share, based on
Lucent's April 1, 1999 close of $55.875. The exchange rate reflects the
two-for-one split of Lucent's stock effective April 1, 1999.

        In order to facilitate pooling of interests accounting, Mosaix announced
it will terminate its stock repurchase program and reissue approximately 2.8
million common shares. Including these additional shares, the value of the
transaction would be approximately $145 million, based on Lucent's closing price
on April 1.

        The merger, which is expected to be completed in the quarter ending June
30, 1999, is projected to be neutral to earnings in fiscal 1999 and slightly
accretive in fiscal 2000.

        Lucent estimates the addressable global market for customer relationship
management solutions -- including software, systems and services -- is currently
at $11 billion and is growing at 27 percent annually.

        "Businesses are working harder every day to build highly profitable,
lifelong relationships with their customers," said Bill O'Shea, president,
Lucent Business Communications Systems. "The combination of Lucent and Mosaix
will help businesses deliver the kind of superior service that keeps customers
coming back again and again - whether through the door, the mail, the phone, the
fax or the web."

        Customer relationship management (CRM) is a multi-faceted approach to
marketing, sales and customer care being used by companies to create long-term
customer relationships and improve their business performance.

        Mosaix's intelligent CRM software, called ViewStar(TM), automates and
streamlines information about customer requests and the tasks required to
fulfill them, producing a way to efficiently manage customer workflow within the
company. The software creates a comprehensive record of customer transactions,
preferences and buying patterns. Among other things it enables a service
representative to respond quickly to a customer, and stimulate more business by
doing things like promoting special products based on buying patterns that have
been identified. In addition, ViewStar enables companies to manage and implement
a variety of enterprise-wide service levels to meet customers' needs.

        Built to run on a Microsoft(R) Windows NT(R) platform, the software
works with a variety of switches, integrated voice response systems and
relational databases, further improving Lucent's ability to support multivendor,
multimedia call centers anywhere in the world.

        "As businesses seek the most effective ways to attract and retain
customers, they're relying more and more on intelligent software," said Janice
Anderson, Lucent Customer Care Solutions vice president. "We've seen nothing
that comes close to Mosaix's exceptional ability to integrate the front-office
call center with customer and business information across the enterprise. Mosaix
and its visionary people are a great addition to our business and a great
investment for Lucent's future."

        Mosaix also offers outbound calling and call blending solutions for call
centers and a suite of agent effectiveness tools. Its team of consultants, who
are experts in CRM and customer care, will enable Lucent's NetCare(R)
Professional Services to build on its consulting business throughout the world.

        "Lucent is leading a communications revolution, where customer service
is more than a buzzword, and winning customers with every interaction is a
business imperative," said Nicholas A. Tiliacos, Mosaix president and CEO.
"Mosaix understands the importance of effectively managing customer
relationships, and we're delighted to bring our technology, our industry
experience and our people to work with Lucent."

        Mosaix employs approximately 550 people, and has more than 1,000
business customers using its software, systems and services solutions in the
United States, Canada, Europe, Asia, Africa and South America.

        The combination of Lucent and Mosaix will expand Lucent's suite of
award-winning CentreVu(R) customer care solutions. CentreVu products are used by
more than 18,000 business locations worldwide to provide superior call center

        The merger is subject to the approval of Mosaix shareholders and other
customary conditions. Mosaix has not determined whether the proposed issue of
approximately 2.8 million shares will be made through a public offering or a
private placement. Any public offering will be made only by a prospectus.
