 PEREGRINE SYSTEMS-Registered Trademark- AND HARBINGER-Registered Trademark-
ANNOUNCE MERGER TO CREATE LARGEST, MOST COMPlETE E-BUSINESS SOLUTIONS PROVIDER

                TRANSACTION BUILDS MARKET GIANT FOR B2B COMMERCE

                  SAN DIEGO, Calif. and ATLANTA, Ga. (April 5, 2000) --
Peregrine Systems, Inc. (NASDAQ: PRGN), the leading provider of Infrastructure
Management and e-Procurement software solutions, and Harbinger Corporation
(NASDAQ: HRBC), the leading provider of B2B e-Commerce delivery solutions, today
announced a definitive merger agreement. The deal combines the strengths of two
companies with premier track records for fully integrating e-Business processes
for Infrastructure Management, e-Procurement and e-Marketplaces (portals), and
rapidly deploying best-in-class e-Business solutions. The combined company will
enable businesses to access multiple e-Marketplaces for requisitioning,
acquiring, managing and disposing of critical assets, facilities and other
operating resources. With 44,000 customers and e-Marketplaces already processing
more than one million mission-critical transactions daily, the company will be
by far the largest provider of end-to-end e-Business solutions.

                  Under the agreement, Peregrine Systems will acquire all of the
outstanding stock and stock options of Harbinger at an exchange ratio of 0.75
share of Peregrine Systems

                                       1




common stock for each share of Harbinger common stock. The stock-for-stock
exchange represents a deal valued at approximately $2.1 billion based on the
closing price of Peregrine Systems shares on April 5, 2000. Peregrine Systems
expects to issue approximately 36 million shares in exchange for all the
outstanding equity securities of Harbinger. The transaction is expected to be
accounted for by the purchase method and treated as a tax-free
reorganization. The definitive agreement has been approved by the Boards of
Directors of both companies and is subject to approval by their respective
shareholders, regulatory approvals and customary closing conditions.

"The combination of Peregrine Systems and Harbinger reshapes the competitive
landscape for end-to-end e-Business solutions," said Steve Gardner, president
and CEO, Peregrine Systems. "As a single provider, we will create, operate and
link e-Business networks, e-Catalogs and online marketplaces, while managing the
full lifecycle and infrastructure of e-Business. Harbinger is the most advanced
and open B2B e-Commerce delivery organization in the world, which makes it a
logical addition to our Infrastructure Management software solutions. The
combination is powerful and creates the clear market leader for e-Business
solutions delivery," added Gardner.

        A. Merger Extends Infrastructure Management and e-Procurement
to e-Business

The merger will combine Peregrine Systems industry-leading e-Procurement,
asset and infrastructure management, and employee self-service solutions with
Harbinger's harbinger.net-SM- e-Marketplace enablement capabilities. Enabling
services via the e-Marketplace include catalog content management, e-Commerce
data transformation, integration and transaction processing, and e-Commerce
Application Service Provider (ASP) offerings.

The merger will create a company that for the first time delivers comprehensive
capabilities to implement the complete lifecycle of e-Business along with
unparalleled worldwide deployment services that help businesses rapidly deploy
broad-based B2B initiatives. Integrated capabilities include:

- -        Reliable Infrastructure
- -        e-Procurement
- -        e-Marketplace Access
- -        e-Catalog Content Management
- -        e-Business Networks
- -        e-Business Community Integration
- -        Employee Self Service
- -        Infrastructure Management

                                       2




Large enterprises will now be able to purchase a full suite of electronic
trading and procurement solutions from a single global supplier, including
integration to their asset management and other business systems. This
combination will also present a compelling value proposition for small-to-medium
size enterprises (SMEs) who will benefit through the availability of full
lifecycle, integrated e-procurement and asset management capabilities offered
via an ASP solution hosted on harbinger.net, the industry's leading
e-Marketplace enablement portal.

"e-Business is all about managing and connecting the internal processes of
e-Procurement and Infrastructure Management to multiple external marketplaces,
so buyers and sellers can rely on their e-Business technology to be more
effective," said James M. Travers, president and CEO of Harbinger. "With 2,500
employees worldwide, more than 44,000 customers including 90% of the Fortune
500, Peregrine Systems and Harbinger can deliver a compelling solution to
businesses of all sizes, with rapid startup and low risk. Customers need to ask
themselves if other B2B suppliers have effectively demonstrated the ability to
create, operate and deliver a complete end-to-end solution and open marketplace
to assure their e-Business success," concluded Travers.

A conference call to review the merger will be held Thursday, April 6, 2000 at
8:00AM EDT, 5:00AM PDT. The dial-in number for the call is 212-896-6100.
