ITEM 1. BUSINESS

     Harbinger Corporation ("Harbinger" or the "Company") is a leading worldwide
provider of business-to-business ("B2B") electronic commerce ("e-commerce")
products and services, offering comprehensive, scalable, standards-based,
solutions for businesses of all sizes. The Company develops, markets and
supports B2B e-commerce software products and provides network communications
and consulting services that help businesses fully automate the cycle of
transactions required in the electronic procurement of goods and services.
Harbinger is differentiated in the B2B e-commerce market by its core competency,
which focuses on the end-to-end process of building, managing and integrating
complete electronic trading communities (e.g., groups of companies that
regularly exchange B2B e-commerce transactions). The Company believes that this
end-to-end process requires domain expertise both as a technology and services
provider, but also as a trusted intermediary, which includes managing the
exchange and integration of mission-critical transactions, developing and
facilitating electronic procurement catalogs ("e-catalogs"), enabling and
deploying electronic marketplaces and vertical market exchanges, and managing
the on-going trading relationships between businesses using these marketplaces
and exchanges to communicate their purchasing and settlement transactions with
each other.

     Harbinger's software products enable businesses to engage in e-commerce
with one another by fully integrating e-commerce into their business
infrastructure and operations. The software is designed and compatible for use
with the most commonly used computer platforms and operating systems, and
provides secure and reliable transmission of e-commerce data between businesses
via the Internet and legacy networks. Harbinger offers the software as
customer-licensed applications for operation on an end-user's server, or on a
subscription basis as an Application Service Provider (ASP) in which the
software is hosted on Harbinger's servers and accessed by customers via the
Internet. Harbinger provides e-commerce delivery and implementation services for
its software, including installation, training and on-going customer support,
and additionally the integration of the software (and resulting e-commerce data)
with a customer's business systems. Delivery and implementation services can
also include outsourcing services for the operations management of a customer's
e-commerce systems, and management of a customer's e-commerce trading community
program. Harbinger additionally offers e-commerce network communications and
trusted intermediary services via its e-commerce portal on the Internet. The
e-commerce center facilitates electronic transaction exchange between businesses
using Internet Protocol ("IP"), the underpinning for the Internet, Intranets,
Extranets, Web sites and e-mail, and over standard telephone lines using non-IP
protocols, such as X.400, X.25 and Bisync. The Company's B2B e-commerce products
and services are deployed in many combinations to suit the individual needs of
its customers, resulting in a comprehensive, scalable, standards-based,
e-commerce solution for each customer, thus maximizing the number and value of
their e-commerce trading relationships with other businesses. As of March 31,
2000, the Company's

     Harbinger focuses day-to-day business operations on five corporate
priorities: (i) revenue growth; (ii) customer value renewal; (iii)
knowledgeable, committed and motivated team; (iv) operational excellence; and,
(v) infrastructure expansion. To achieve its objectives in these areas, the
Company announced that during 2000 it expected to: (a) increase market awareness
of Harbinger as the leading B2B e-commerce solutions provider; (b) capitalize on
its e-commerce center (harbinger.netSM) as the leading portal for
mission-critical B2B e-commerce; (c) complete the conversion of its
approximately 40,000 existing customers to Internet-enabled products and
services; and, (d) maintain operational excellence throughout the Company.

B2B E-COMMERCE

     Business-to-business e-commerce involves the automation of business
processes and transactions through the use of computers and telecommunications
to exchange and electronically process commercial information and transactions
between businesses. In the 1980s, the predominant technology for B2B e-commerce
was standards-based data exchange, which facilitated the computer-to-computer
exchange of business transactions between trading partners using formatted
messages. The transactions, typically purchase orders, shipping notices,
invoices and related confirmations, were communicated between businesses over
private service networks, known as value-added networks ("VANs"), which provided
security, auditability and delivery for transactions. In the 1990s, IP-based
networks including the Internet became more prominent in the B2B e-commerce
market and have greatly expanded the opportunity for software functionality,
types of transactions and the data communications of such transactions between
businesses.

     The advantages of B2B e-commerce typically include one-time or eliminated
data entry, reduced clerical workload, elimination of paper records, rapid,
accurate and secure exchange of business data, and reduced operating and
inventory carrying costs. B2B e-commerce, for example, facilitates uniform data
communications between trading partners in different industries, including
customers, suppliers, common carriers, banks and other financial institutions.
Standards-based data exchange remains a cornerstone of e-commerce and has
historically been the source of the majority of Harbinger's revenue. The Company
expects IP-based revenue to increase as a percentage of its total revenue.
Nevertheless, many B2B e-commerce transactions, including those generated by new
IP-based software applications, follow a common transaction flow originally
established using standards-based data exchange.

     Transaction Flow. B2B e-commerce transactions follow specific execution
methods. The following outlines a typical purchasing transaction. First, a
trading partner (the "sending partner") creates with its computer, either
manually or

                                       2

<PAGE>   4


electronically, the raw business data for the purchase order. Business data for
manual transactions may be created by selecting items from an e-catalog, whereas
automated transactions may be dynamically created by the sending partner's
business systems according to predetermined criteria for inventory levels, sales
forecasts, etc. Second, e-commerce software on the sending partner's computer
converts the raw business data into an acceptable, standards-based, e-commerce
purchase order. Third, the purchase order, now in e-commerce format, is
electronically transmitted through telecommunications links from the sending
partner's computer to the central server of a trusted third party that serves as
the transactional intermediary for many trading partners. Telecommunications
could be point-to-point between trading partners, but the predominant model
remains through intermediaries for reasons of security, auditing and ease of
delivery. Fourth, the intermediary receives and processes the transaction for
subsequent delivery to the intended trading partner (the "receiving partner").
Fifth, the receiving partner uses e-commerce software, but not necessarily the
same brand of e-commerce software employed by the sending partner, to act on the
purchase order. Sixth, based on the receiving partner's actions, a follow-up
transaction (e.g., order confirmation) is created and communicated back to the
sending partner ostensibly following the same procedures outlined in steps 1-4
above. The transaction exchange, following prescribed execution methods and
standard transaction sets (i.e., quotes, purchase orders, shipping and receiving
notices, invoices, payments and related transaction), continues between the
partners through invoicing and settlement.

     Trading Communities. Groups of companies that regularly trade with each
other generate a significant number of repetitive business transactions. These
groups and the individual companies that comprise their trading communities are
prospects for the implementation of B2B e-commerce solutions. Early market
expansion of B2B e-commerce and its associated trading communities was made
possible through the establishment of repetitive standard transactions sets
based on the ANSI X.12 and UN/EDIFACT formats. There are now subsets of these
standards in use across specific industries such as automotive, banking,
chemical, financial, grocery, healthcare, petroleum, retail and utilities. The
adoption of these standards-based formats as an accepted means of transaction
exchange has occurred, in part, because many groups and trade organizations and
many large companies within vertical communities increasingly recommend or
require their member organizations or trading partners to adopt such formats as
the primary method of communicating business transactions. The vast majority of
today's B2B e-commerce transactions utilize these standard and subset formats.
With the growth of IP-based e-commerce, the market is also seeing new formats
emerge such as extensible markup language ("XML") and open buying over the
Internet ("OBI"), which like standards-based data exchange in the 1980s must
first achieve market acceptance.

     Marketplaces and Vertical Market Exchanges. Several B2B e-commerce trading
models have evolved in the market over time including enterprise-centric,
consortium and open market. The predominant model, enterprise-centric (also
"e-hub" and "hub and spoke"), dates back to the 1980s, where large companies
within a trading group exercised substantial influence over how the group
exchanged B2B e-commerce transactions. This one-to-many trading model grew up in
vertical markets where there were clear industry leaders conducting business
around a specialized group of products. Within B2B e-commerce, the consortium
and open market trading models have emerged in recent years. The consortium
model is similar to the enterprise-centric model except that several large
enterprises, sometimes in joint-ventures which include e-commerce technology
suppliers, band together to build a marketplace for the exchange of
commodity-oriented goods and services. In contrast, the open market model is a
many-to-many marketplace for the exchange of commodity-oriented goods and
services, where no clear business leaders can dominate the playing field.
Transactions within these trading models can flow via Internet or Extranet,
public and private third-party networks. The process of building, managing and
integrating complete electronic trading communities around these e-commerce
trading models has a cascading effect across business segments and markets.
Large companies attract mid-market companies, who in turn attract smaller
enterprises to engage in B2B e-commerce, thus creating an integrated and
automated supply chain. This natural evolution and growth results in potential
new customers for B2B e-commerce software, network communications and consulting
services.

     According to GartnerGroup, B2B e-commerce transactions will grow to reach
$7.3 trillion worldwide by 2004. Furthermore, Company management estimates that
of the 3 million U.S. companies with five or more employees, approximately
200,000 (including virtually all of the Fortune 500) have elected to date to
make use of B2B e-commerce, representing about $45 billion in transaction value.
Although many of these businesses are members of existing trading communities,
the Company believes that the majority use B2B e-commerce to communicate with
only a small percentage of their suppliers, distributors and customers. For B2B
e-commerce to achieve analyst growth estimates over the next few years, the
Company believes penetration and adoption rates within the mid-market and small
enterprise will need to sharply increase. Adoption of B2B e-commerce and
expansion within trading communities will depend on various factors, such as the
extent of automation in the industry, the degree to which companies require
electronic trading from their trading partners, the level of computer
sophistication of businesses in the trading community, the frequency of
transactions among trading partners in the community and the economic benefits
derived from the trading community by implementing electronic trading, which
historically have accrued principally to the larger members of the community.

THE INTERNET AND INTERNET PROTOCOL

     The Internet is a collection of interconnected public and private networks
that allows any computer on the network to communicate with any other computer
on the network over IP. IP is the common denominator for the Internet as well as
for corporate Intranets, Extranets, Web sites and e-mail. Although the Internet
affords a lower cost, more robust, and widely available medium for B2B
e-commerce telecommunications, there are significant actual and perceived
concerns relating to the use of the Internet for commercial transactions. These
concerns include security, inability to confirm message integrity, vulnerability
of messages to interception and fabrication, lack of user support, service or
centralized "help desk" support, and difficulties in obtaining reliable
assurance of receipt of messages sent or the authenticity of messages received.
These difficulties inherent in the Internet are magnified when the Internet is
used to transport commercial, mission-critical, B2B e-commerce transactions.

     To solve the current problems with using the Internet and other IP networks
for transporting B2B e-commerce transactions, the Company offers a series of
products and services. The harbinger.net e-commerce center provides trusted
intermediary services including those for message integrity and accountability,
and centralized online customer support. Harbinger software products that
operate as Extranets, but do not require a Web browser interface, include secure
communications to harbinger.net using secure sockets layer ("SSL"), a security
protocol that is widely accepted for IP networks. Harbinger Express is an
e-commerce Extranet product using a Web browser interface and the browser's
native SSL component for secure transmission of transactions to harbinger.net.
Harbinger Templar(R) is an e-commerce e-mail product using patented and industry
standard encryption technologies for the highly secure transmission of
transactions to harbinger.net and directly between trading partners.

THE HARBINGER SOLUTION

     The Harbinger solution to address B2B e-commerce focuses on building,

customers the flexibility of purchasing Harbinger's solution as a licensed
application set or on a subscription basis as a network-delivered service via
harbinger.net.

     Migrate Customers to IP-based Products and Services. The Company believes
IP-enabled products and services amplify its ability to provide enhanced
features and improved service levels to its customers. As a result, throughout
1999 the Company engaged in a comprehensive marketing effort to migrate its
customers to IP-based products and services, with a goal of achieving a 50%
penetration by year-end. The Company is continuing the migration program during
2000 and intends to achieve further penetration by year-end.

     Provide a Comprehensive Range of Integrated Products and Services. All
products and services offered by the Company are or are expected to be
IP-enabled, and include e-commerce software for use on the full range of
commonly used computer platforms and operating systems, along with
industry-standard applications (e.g., Web browsers) where required. Harbinger
designs its products and services to include significant ease-of-use features
while providing a high degree of maintainability and supportability across the
customer and product life cycles. Customer self-services for problem reporting,
trouble shooting, software updates and similar services are available via online
connection to the harbinger.net e-commerce center. The software supports
standard formats and transactions for e-commerce, including X12, EDIFACT and
XML, and is designed to be adaptable to emerging B2B e-commerce facilitates such
as OBI, RosettaNet and BizTalk. While certain software is designed for
installation by the customer, more sophisticated e-commerce applications often
require delivery and implementation assistance provided by Harbinger's
professional services group. Such instances typically include specific customer
requirements for data transformation, as well as integration of the resulting
data with the customer's business systems including popular enterprise resource
planning ("ERP") systems. Finally, all the products and services are compatible
with the Company's harbinger.net e-commerce center and seeks to drive recurring
revenue through subscription and transaction volume.

     Focus on Building, Managing and Integrating Trading Communities. Harbinger
seeks to establish new and larger trading communities by (i) developing
marketing and technical competence within specific industries by understanding
the needs of major trade organizations and leading enterprises in the industry,
and the trading customs and practices of their trading partners, (ii) working
closely with trading partners to define software and information processing
requirements, (iii) developing trading community solutions that meet the needs
of trading partners in these markets, and (iv) providing a wide array of
value-added, high-quality products and services to facilitate the adoption and
implementation of B2B e-commerce solutions across these industries.

     Develop New B2B Technologies. The Company's research and development
("R&D") organization is continually working to improve the features, performance
and serviceability of its going-forward products and services. The group follows
the Software Process Handbook and Product Life Cycle Methodology to adhere to
the Software Engineering Institute Capability Maturity Model, which measures the
quality and stability of software per line of code. The R&D group is currently
evaluating an upgrade to its development standards for 2000, such as Rational
Unified process, to better standardize its software development around
object-oriented programming. Additionally, the Company is currently engaged to
develop new B2B e-commerce products and services through Harbinger Labs, a
separate group within its R&D organization. Harbinger Labs is focused on new B2B
e-commerce technologies for rollout in the 2001 through 2004 timeframe.

     Penetrate Worldwide Markets. The Company intends to aggressively pursue
worldwide B2B e-commerce opportunities in Europe, the Middle East and Africa
("EMEA"), and Asia-Pacific and Latin American ("APLA") theaters. The

Company has a direct presence in the United States, Canada, Germany, Italy,
Mexico, The Netherlands and the United Kingdom. Indirect channels are maintained
through distributors in countries where Harbinger does not have a direct
presence and complements the Company's direct sales, marketing and support
initiatives in the EMEA and APLA theaters.

     Maintain Operational Excellence. Harbinger's value-proposition is based on
a business model of operational excellence. This business model enables the
Company to pursue sustainable competitive advantage through its ability to
deliver products and services to customers at the lowest possible cost, with the
highest degree of quality and efficiency, backed by expert customer care. The
Company is implementing total quality management ("TQM") processes across the
organization and expects to achieve ISO 9001 certification by year-end 2000. The
Company strives to make itself the easiest to do business among all B2B
e-commerce providers.

     Pursue Strategic Acquisitions and Alliances. The Company intends to enter
new vertical markets, penetrate additional geographic markets and expand its B2B
e-commerce product and service offerings. The Company will continue to seek to
acquire complementary technologies and businesses opportunistically, when
appropriate and supportable. The Company has in the past completed acquisitions
to address other e-commerce opportunities on the Internet, enter new vertical
markets, acquire complementary technologies and further penetrate international
markets. The Company also actively seeks strategic alliances with leading
professional services companies, software application developers and computer
system suppliers to resell, distribute and co-market the Company's B2B
e-commerce products and services.

     Investment Division for Emerging Marketplace. The Company announced in
January 2000 that it was forming a new investment division with $25 million
allocated to capitalize emerging marketplaces and vertical market exchanges
hosted on harbinger.net. Vulcan Ventures, Inc., Paul Allen's venture capital
firm and one of the Company's largest and longest standing shareholders, also
plans to invest side by side with Harbinger as the Company builds equity stakes
in the emerging Internet startups. The division will be separately staffed, and
allow the Company to evaluate new opportunities and make investment decisions in
a highly competitive and rapidly changing market environment.

CATALOG DATA MANAGEMENT

     Harbinger Knowbility. Harbinger Knowbility is a comprehensive suite of
software tools for buyers and suppliers to create, load, manage and maintain
e-catalogs. Rationalizing data from existing paper catalogs and electronic
repositories to create e-catalogs is often the number one challenge faced by
companies trying to establish an online purchasing system. The Knowbility suite
produces fully rationalized data elements for fast search and accurate retrieval
by popular catalog search engines. E-catalog data and technology have been
applied in both supply chain management initiatives for production goods and
services, and maintenance, repair and operating ("MRO") supplies for
non-production goods and services. Additionally, Harbinger offers complete
outsourcing services for e-catalog development and maintenance, Application
Service for hosting of e-catalogs on harbinger.net.

APPLICATION SERVICES AND SOFTWARE

     Harbinger Application Services. Harbinger Application Services provides
businesses of all sizes subscription-based access and usage of Harbinger
e-commerce software, which is hosted for them on the harbinger.net e-commerce
center. In a market experiencing rapid advancement and change, many businesses
are opting to "rent" (ASP) versus "own" (license) software applications, thus
conserving capital for other strategic initiatives. Harbinger Application
Services can be tailored to the specific needs of each business including any
combination of software usage, transaction exchange and support services across
the complete range of Harbinger e-commerce software and e-catalog tools.

     Harbinger Marketplaces and Vertical Market Exchanges. Harbinger
Marketplaces and Vertical Market Exchanges are power by Harbinger's advanced IP
gateway technologies for rapidly creating, deploying, managing and operating
electronic marketplaces, which conform to the enterprise-centric, consortium and
open market trading models in today's environment for B2B e-commerce. Deploying
a full-service, real-time, end-to-end electronic marketplace requires more than
a Web site.


                                       9

Harbinger's one-to-many and many-to-many online exchanges may be operated on the
sponsor's servers or hosted on harbinger.net under Harbinger's ASP program, and
can be configured with complete front- and back-office e-commerce
infrastructures to manage the entire customer life cycle from recruitment to
registration, to on-going transaction exchange and billing.

     Harbinger Express. Harbinger Express is a Web-enabled application that
allows a business on one end of an e-commerce transaction to exchange
transactions with their trading partner using only an Internet connection and
standard Web browser. Frequently the application is used by small and mid-size
enterprises ("SME") that have been reluctant to implement full-scale e-commerce
systems within their businesses. Express applications are often sponsored by
larger enterprises wanting to expand their trading communities with SME trading
partners. Express automatically translates e-commerce transactions to and from
hypertext markup language ("HTML") so that trading partners using a Web browser
on one end of an exchange receive e-commerce transactions as Web pages, while
more sophisticated trading partners on the other end of an exchange receive
e-commerce transactions in their preferred format (i.e., XML, X12, EDIFACT,
etc.). For more complex business requirements, the SMEs can use an optional
Windows client application, which supports offline document processing and
application integration.

     Harbinger TrustedLink. Harbinger TrustedLink is a family of data
transformation and integration software that permits the rapid creation and
exchange of e-commerce transactions across a comprehensive range of e-commerce
standards such as XML, X12 and EDIFACT. The product family is used by businesses
of all sizes engaged in full-scale e-commerce programs. TrustedLink facilitates
the creation and control of business transactions, such as purchase orders and
invoices, and provides data integration and messaging functions for directly
interacting with a company's internal business systems, including popular ERP
systems.

     The Windows version of TrustedLink is the leading B2B e-commerce software
product for the desktop computer market. The OS/400 version of TrustedLink is
the leading B2B e-commerce software product for the mid-range computer market,
operating on the IBM AS/400 computer. The AS/400 is the leading mid-range
platform installed worldwide for use as either the main computer for a small or
mid-sized business or as a departmental or dedicated processor in a larger
business.

     Harbinger Instant Net Presence. Harbinger INP allows a company to establish
an Internet storefront for their business including a professional Web site and
online catalog and ordering suite. The software is designed for SMEs typically
implementing their first e-commerce sites and requires no programming skills.
Users create their Internet storefront by entering information to the software
following an interview format. The storefront can be previewed locally on the
desktop using the embedded Microsoft Internet Explorer software, and published
for use on the Internet via Harbinger's ASP program hosted on harbinger.net.

     Harbinger Templar. Harbinger Templar is an open, standards-based solution
for enabling secure transmission of digitally designed electronic documents,
including XML, X12 and EDIFACT documents, over the Internet and other IP
networks. Templar supplies security for message transmissions by utilizing
public key cryptography techniques licensed from RSA Data Security, Inc. and by
implementing security and confidentiality features at the software application
level. Templar generates a digital signature for each outbound message that
verifies the identity of the sender and automatically detects any alteration of
the message upon receipt. Templar automatically tracks message traffic and
message integrity and authenticity and provides user-configurable management
reports. Templar also maintains transmission records for audit trails. Harbinger
markets an exportable version of Templar in compliance with current U.S. export
control laws and regulations applicable to encryption technology. Harbinger
Templar is protected under U.S. Patent.

     Harbinger Prime Factors. Harbinger Prime Factors enables banks and other
businesses to secure financial and other information transmitted over internal
and external networks. Customers include money center banks, large corporations
and government agencies interested in securing data transmitted internally and
externally. Prime Factors products operate on computer platforms such as desktop
PCs, mid-range UNIX and AS/400, DEC and Tandem machines to MVS mainframes.

E-COMMERCE SERVICES

     Harbinger Business Community Integration. Harbinger Business Community
Integration ("BCI") offers outsourcing services for building, managing and
integrating complete electronic trading communities with suppliers, distributors
and customers. Many companies do not want the burden of finding new trading
partners, integrating them into existing e-commerce program, or managing the
ongoing electronic relationships across all trading partners. BCI is a tailored
service to meet the specific trading community needs of each business. The
program includes full-service capabilities for implementation


                                       10

and execution of marketing programs, information seminars, support materials,
telemarketing, trading format creation and distribution, software and services
delivery, installation assistance, testing and certification of e-commerce
software and telecommunications with all trading partners.

     Harbinger Operations Management (Outsourcing). Harbinger Operations
Management provides outsourcing services for the operation of Harbinger software
applications hosted on customers' servers. Many companies want to conserve
in-house IT resources for strategic initiatives other than e-commerce, opting to
rely on outside expert services for the operation and maintenance of their
e-commerce infrastructure. Operations Management is a tailored service to meet
the specific e-commerce operational needs of each customer. Harbinger staff
provides outsourcing services either onsite or remotely.

     Professional Services. Harbinger Professional Services is staffed by
technical consultants providing project management, installation, integration
and ongoing services for Harbinger software applications and e-commerce
implementations. This is particularly important for the many companies today
that are building end-to-end e-commerce infrastructures, which include
application-to-application interfaces between their internal business systems
and those of their trading partners. These integrated trading relationships
require e-commerce software to be tightly coupled with internal business
systems, including ERP systems, and communicate in real-time via the Internet or
near real-time via private networks and VANs. Harbinger Professional Services
specializes in the delivery and implementation of Harbinger software within
complex trading environments.

     E-Commerce Project Services. Harbinger E-Commerce Project Services
specializes in the development and implementation of e-commerce solutions that
leverage Harbinger applications and services.

care and ongoing support facilities related to the use and operation of
Harbinger software applications, network services and the business processes
associated with e-commerce. Customers can tailor their support program to
include annual maintenance with software updates and product enhancements, along
with any combination of no-charge and fee-based services. Harbinger operates
multiple hotline "help desks" across North America, Europe and Mexico. 24x7
customer self-services for problem reporting, trouble shooting, software
upgrades and downloads are available via online connection to the harbinger.net
e-commerce center.

SALES AND MARKETING

     Harbinger's principal marketing strategy focuses on establishing complete
electronic trading communities and expanding the number of trading partners
using Harbinger software and the harbinger.net e-commerce center. The Company
targets trading communities composed of trading partners in common industries or
markets conducting recurring business transactions. To achieve this objective,
the Company has developed a sales and distribution function that includes direct
and indirect channels to promote the implementation of B2B e-commerce within
trading communities primarily conforming to the enterprise-centric trading model
and secondarily to the consortium and open market trading models. Within its
direct selling operations, the Company utilizes a solutions selling approach to
address the needs of its customers and prospective customers.

     Direct. Harbinger has direct selling operations based in North America,
Europe and Mexico. Applying the best practices associated with solutions
selling, the Company's direct sales organization seeks to have customers license
or subscribe to (under an ASP program) its software and sell network and
e-commerce services to businesses of all sizes that address the needs and
requirements of those businesses e-commerce objectives. As of March 1, 2000, the
Company employed approximately 250 sales and marketing personnel. The Company's
compensation strategies are designed to reward sales personnel based upon sales
to new customers and the sale of additional products and services to existing
customers.

     Indirect. Harbinger seeks to complement its direct selling operations
through referral partners and distributors, and relies on distributors in the
Latin American and Asia-Pacific theaters. Through various alliance programs, the
Company has established relationships with referral partners, distributors,
application software developers, systems integrators and value-added resellers
of computer products. The Company's objective is to integrate Harbinger's
products with those of its business partners and to promote distribution of
Harbinger software along with products and services sold by its marketing
partners. The Company fosters relationships with software vendors who bundle or
imbed the Company's products with their own products, or which resell the
Company's products in particular trading communities. Distributors typically
sublicense the Company's software to end-user customers and pay the Company a
royalty, while co-marketers typically forward leads to the


                                       11

<PAGE>   13


Company in exchange for a percentage referral fee if the sale is completed. The
Company has relationships with partners such as AT&T, Ariba, Baan, Clarus,
Computer Associates, Computer Generated Solutions, Concur, daly.commerce, Data
General, Deloitte Consulting, Entrust Technologies, Ernst & Young,
Hewlett-Packard, IBM, Intentia, JBA, J.D. Edwards, MAPICS, Marcam, Microsoft,
OnDisplay, Optika, Oracle, Peachtree Software, PeopleSoft,
PricewaterhouseCoopers, PurchaseSoft, RightWorks, SAP, Sprint, Sun-Netscape
Alliance, Sybase, Syntegra Unisys and UUNET Technologies for distribution of its
products worldwide.

PRODUCT DEVELOPMENT

     The Company continues to assess the needs of businesses in various trading
communities and to develop software programs and network services, which
facilitate B2B e-commerce transactions via the harbinger.net e-commerce center,
or directly over standard telephone lines. The Company's product development
efforts currently are focused on providing a full range of B2B e-commerce
solutions to Harbinger customers and prospective customers. In addition, the
Company has incorporated into its products certain software licensed to it by
other software developers, where appropriate, to reduce product development
time.

COMPETITION

     The B2B e-commerce services and computer software markets are highly
competitive. Numerous companies supply B2B e-commerce network services, and
several competitors target specific vertical markets such as the pharmaceutical,
agri-business, retail and transportation industries. Additional competitors
provide software designed to facilitate e-commerce transactions and e-catalog
systems and services. Several of the Company's most significant competitors
provide network services and related software products and services. The Company
believes that many of its competitors have significantly greater financial and
personnel resources than the Company, due in part either to their revenue and
profitability, or market capitalization.

     The market for Internet B2B e-commerce software and services is also highly
competitive, ranging from small companies with limited resources to large
companies with substantially greater financial and marketing resources than the
Company. The Company believes that existing competitors are likely to expand the
range of their e-commerce services to include Internet-based capabilities, and
that new competitors, which may include telephone companies and media companies,
are likely to increasingly offer services which utilize the Internet to provide
B2B e-commerce services. Additionally, several competitive network service
providers allow their subscribers access to the Internet, and several major
software and telecommunications companies have Internet access services.

     The Company believes the principal competitive factors in the commercial
B2B e-commerce industry include responsiveness to customer needs, efficiency in
the delivery of solutions, ease of product use, quality of service, price and
value. The Company believes it competes favorably with regard to these factors.

INTELLECTUAL PROPERTY RIGHTS

     In accordance with industry practice, the Company relies primarily on a
combination of copyright, patent and trademark laws, trade secrets,
confidentiality procedures and contractual provisions to protect its proprietary
rights. The Company seeks to protect its software, documentation and other
written materials principally under trade secret and copyright laws, which
afford only limited protection. The Company presently has one U.S. patent for an
electronic document interchange test facility, one U.S. patent for technology
utilized in the Company's EDI/Open product and one U.S. patent for an EDI
communication system and for technology utilized in the Company's Templar
product. The Company routinely enters into non-disclosure and confidentiality
agreements with employees, vendors, contractors, consultants and customers.
Despite the Company's efforts to protect its proprietary rights, unauthorized
parties may attempt to copy aspects of the Company's products or to obtain and
use information that the Company regards as proprietary. There can be no
assurance that the Company's means of protecting its proprietary rights will be
adequate or that competitors will not independently develop similar technology.
The laws of certain foreign countries in which the Company's products are or may
be developed, manufactured, licensed or distributed may not protect the
Company's products or intellectual property rights to the same extent as do the
laws of the United States and thus make the possibility of piracy of the
Company's technology and products more likely. The Company believes that, due to
the rapid pace of innovation within the electronic commerce, EDI and related
software industries, factors such as the technological and creative skills of
its personnel are more important in establishing and maintaining a leadership
position within the industry than are the various legal protections of its
technology. The Company does not believe that any of its products infringe the
proprietary rights of third parties. There can be no assurance, however, that
third parties will not claim infringement by the Company with respect to current
or future products. From time to time, the Company has received notices which
allege, directly or indirectly, that the Company's products or other
intellectual property rights infringe the rights of others. The Company
generally has been able to address these allegations without material cost to
the Company. There can be no assurance, however, that the cost to the Company of
addressing these allegations will not increase in the future. The Company
expects that software product developers will increasingly be subject to
infringement claims as the number of products and competitors in electronic
commerce grows and the functionality of products in different industry segments
overlaps. Any such claims, with or without merit, could be time-consuming,
result in costly litigation, cause product shipment


                                       13

<PAGE>   15


delays or require the Company to enter into royalty or licensing agreements.
Such royalty or licensing agreements, if required, may not be available on terms
acceptable to the Company or at all, which could have a material adverse effect
on the Company.

     In its distribution agreements and certain of its customer or other
agreements, the Company agrees to indemnify certain parties, which may include
customers of parties with which the Company has contracted, for any expenses or
liabilities resulting from claimed infringements of patents, trademarks or
copyrights or certain other intellectual property rights of third parties. In
the event of litigation to determine the validity of any third-party claims,
such litigation, whether or not determined in favor of the Company, could result
in significant expense to the Company and divert the efforts of the Company's
technical and management personnel from productive tasks. In the event of an
adverse ruling in such litigation, the Company might be required to pay money
damages, to discontinue the use and sale of infringing products, to expend
significant resources to develop non-infringing technology or obtain licenses
from third parties. There can be no assurance that licenses from third parties
would be available on reasonable commercial terms, if at all. In the event of a
successful claim against the Company and the failure of the Company to develop
or license a substitute technology, the Company's business and operations
results would be materially adversely affected.

     Third Party Technology. The Company incorporates in its products certain
software licensed to it by other software developers. These include the public
key cryptography software licensed by RSA Data Security, Inc. to Premenos which
is used in connection with Templar as well as certain database software used in
the Templar and EDI/Open products and certain graphical interface software used
in EDI products and Templar.

     Premenos licensed the public key encryption technology pursuant to a
license agreement with RSA (the "RSA License"), which was transferred to
Harbinger in connection with the acquisition of Premenos. The RSA License grants
to the Company the non-exclusive, non-transferable, non-assignable limited
license to incorporate certain functionality within RSA's public key encryption
technology into a Premenos product solely to create a Bundled Product, as
defined in the RSA License, to reproduce and sublicense the Bundled Product, and
to use or authorize end-users to use the Bundled Product in conjunction with a
service bureau or internal network or to provide electronic communications,
messaging and similar services to third parties. A Bundled Product is defined as
a Company product which represents a significant functional and value
enhancement to the RSA technology designed to facilitate the secure exchange of
electronic information such as EDI documents over open networks. The RSA License
contains a number of restrictions regarding sublicensing of the Bundled Product
to act as a certification authority, as well as other restrictions regarding
end-user use, territory and distribution channels. The Company is prohibited
from selling the Bundled Product or any product with comparable functionality
which does not incorporate the RSA encryption technology, except in certain
circumstances, in which event the Company is required to pay the otherwise
applicable royalty fee to RSA.

     The Company also incorporates database software licensed from Sybase, Inc.
into its Templar and certain versions of its EDI/Open products, and incorporates
graphical software licensed from third parties into the EDI products and
Templar. Although the Company seeks and generally receives assurances from
third-party software vendors as to such third party's intellectual property
rights and the non-infringement by such software of other parties' rights,
Harbinger's right to use such software could be impaired by third party claims.
In addition, certain agreements pursuant to which the Company uses such software
may be terminated in accordance with their terms in certain circumstances.

     If the Company were deprived of the right to use software incorporated in
its products for any reason, there could be serious disruption to its business.

YEAR 2000 READINESS

     The Company spent considerable internal and external resources from 1997
through 1999 preparing for the "Year 2000" computer issue. The Year 2000 issue
relates to the ability of a computer system to properly process data beginning
on January 1, 2000. The Company's efforts were spent to ensure that its computer
products were "Year 2000 Ready," as defined, and that its internal core
information technology (IT) and non-IT systems were Year 2000 Ready.

     The Company believes it successfully implemented its Year 2000 program, as
evidenced by the continued successful operation of its computer products and
core internal IT and non-IT systems. The Company has not encountered any
significant problems with its third-party customers, financial institutions,
vendors and others with whom it conducts business. The Company will continue to
monitor its product performance and core IT and non-IT systems throughout 2000
to ensure ongoing performance. While there can be no assurance that no Year 2000
related issues will arise, as of December 31, 1999, the


                                       14

<PAGE>   16


Company believes, based on information currently available, that Year
2000-related events are not likely to have a material effect on its results of
operation, financial condition or liquidity.

     The total pre-tax cost associated with Year 2000 modifications of the
Company's products was approximately $1 million to $2 million, funded from the
Company's internal operating cash flows. Such costs do not include costs for new
internal software or for modifications to existing internal software for the
Company's IT systems, as these projects were not accelerated due to the Year
2000 issue.


EMPLOYEES

     As of March 8, 2000, the Company had approximately 1,003 full-time
employees. Approximately 309 are technical personnel engaged in maintaining or
developing the Company's products or performing related services, approximately
200 are marketing and sales personnel, approximately 314 are customer support
and operations personnel, and approximately 180 are involved in administration
and finance.

GOVERNMENTAL REGULATIONS AND INDUSTRY STANDARDS

     Government Regulatory and Industrial Policy Risks. The Company's network
services are transmitted to its customers over dedicated and public
communications lines. These transmissions are governed by legislative and
regulatory policies establishing charges, terms and conditions affecting
communications. Changes in the legislative and regulatory environment relating
to online services, EDI or the Internet access industry, including regulatory or
legislative changes that directly or indirectly affect telecommunication costs
or increase the likelihood of competition from regional telephone companies or
others, could have an adverse effect on the Company's business. The
Telecommunications Act of 1996 (the "Act") amended the federal
telecommunications laws by relaxing restrictions on regional telephone companies
and others competing with the Company. The Act set in motion certain events that
will lead to the elimination of restrictions on regional telephone companies
providing transport between defined geographic boundaries associated with the
provision of their own information services. This will enable regional telephone
companies to more readily compete with the Company by packaging information
service offerings with other services and providing them on a wider geographic
scale. While some legislative efforts to govern communications especially over
the Internet (most notably, provisions of the Communications Decency Act) have
been held by the U.S. Supreme Court to be unconstitutional, there can be no
assurance that future legislative or regulatory efforts to limit use of the
Internet in a manner harmful to the Company will not be successful. The Clinton
Administration has announced an initiative to establish a framework for global
electronic commerce. The Children's Online Privacy Protection Act becomes
effective April 21, 2000, and this and future governmental privacy initiatives
may affect the Company's provision of services. Also, some countries, such as
Germany, have adopted laws regulating aspects of the Internet, and there are a
number of bills recently adopted or currently being considered in the United
States at the federal and state levels involving electronic transactions,
encryption and digital signatures, all of which may impact the Company. The
Company cannot predict the impact, if any, that these laws and future court
opinions, legislation, regulations or regulatory changes in the United States or
other countries may have on its business. Management believes that the Company
is in compliance with all material applicable regulations. The Harbinger IVAS
product and the Harbinger Templar product both incorporate encryption technology
which is subject to U.S. export control regulations. Although both products are
currently exportable under licenses granted by the Commerce Department,
government regulation in this area is subject to frequent change and there can
be no assurance that these products will remain exportable.


ITEM 2. PROPERTIES.

     The Company occupies approximately 99,560 square feet of office space in
Atlanta, Georgia under a lease expiring in 2008, plus options to extend the
lease term. This location serves as the Company's headquarters and data center.
The Company also has offices in Michigan, Texas, California, South Carolina,
Oregon and Oklahoma, occupying approximately 39,800; 26,000; 73,615; 21,789;
2,100; and 14,700 square feet, respectively. In addition, the Company also has
offices in The Netherlands, Germany, the United Kingdom, Italy and Mexico
occupying approximately 1,600; 14,546; 7,600; 2,228 and 1,614 square feet,
respectively. The Company's offices are generally located in suburban office
park environments.


ITEM 3. LEGAL PROCEEDINGS.

     The Company is involved from time to time in various legal proceedings
incidental to the conduct of its business. In addition, on September 13, 1999,
the Company and three of its current or former officers and directors, C. Tycho
Howle, David Leach and Joel G. Katz, were named in a purported class action
lawsuit alleging violations of Sections 10(b) and 20(a) of the Securities
Exchange Act of 1934. The complaint alleged that during a class period running
from February 4, 1998 through October 1, 1998 defendants made materially false
and misleading statements, and failed to disclose material facts regarding the
Company's business condition, future prospects and integration of acquisitions.
According to the complaint, these purported



                                       16
<PAGE>   18


misrepresentations and omissions artificially inflated the price of the
Company's common stock throughout the class period and resulted in substantial
losses by members of the purported class. On January 13, 2000, the Court entered
an order appointing lead plaintiffs and lead plaintiffs' counsel. On March 6,
2000, plaintiffs filed an amended complaint reiterating and expanding upon the
basic claims asserted in the original complaint by, among other things, adding
allegations regarding the Company's accounting practices. Plaintiffs seek
certification of the case as a class action, a declaration that defendants
violated the federal securities laws, unspecified money damages according to
proof, interest, attorneys' fees and costs. The Company believes all claims
asserted in the action are without merit, and intends to defend the case
vigorously.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

     There were no matters submitted to a vote of security holders during the
last quarter of the year ended December 31, 1999.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS.

OVERVIEW

ABOUT THE COMPANY

     Harbinger Corporation (the Company) generates revenues from e-commerce
enablement services and from licensing software that facilitates the exchange of
electronic data between businesses. Revenues for enablement services principally
include transaction fees on harbinger.net, the Company's e-commerce portal;
subscription fees for access to applications hosted on harbinger.net (ASP);
software maintenance; and professional service fees for operations management
(outsourcing), business community integration (BCI), training, consulting and
project management. Transaction and subscription fees are a combination of
access and usage charges and are recognized as incurred each month. Software
maintenance is billed in advance with revenue deferred and recognized ratably
over the one-year service period. Revenues for professional services are based
on actual services rendered and are recognized as the services are performed.
License fees for software are generally recognized upon shipment, net of
estimated returns. Software revenues also include royalties due the Company
under distribution agreements with third parties which are recognized either on
shipment of software to a distributor, or upon sales to end users by a
distributor, depending on the terms of the distribution agreement.

     The Company also analyzes its mix of revenues in terms of the recurring
versus nonrecurring nature of the revenue streams. The Company includes revenues
from ongoing software maintenance and transactions on harbinger.net, together
with operations management, BCI and ASP services in its definition of recurring
revenues. Recurring revenues are recognized ratably over the contract period as
services are provided or may be billed and recognized on monthly subscription
terms generally over a two- to three-year period. The Company defines
nonrecurring revenues to include one-time professional service enablement
contracts, typically for consulting, project management or implementation
services, and software licenses.

     The Company seeks to maximize its recurring revenue streams in order to: 1)
promote customer retention, 2) provide increased visibility into long-term
revenue and cash flow generating capabilities, and 3) decrease the revenue and
cash flow risk associated with singular professional service and software
license contracts. Accordingly, in 1999 the Company increased its sales and
marketing efforts in its recurring revenue programs. The Company also seeks to
maximize the use of the public Internet as a means of conducting
business-to-business e-commerce. Since 1994, the Company has invested in
enabling its products and services to the Internet and is actively encouraging
its current customer base to migrate to Internet-capable technologies.

STOCK REPURCHASE PROGRAM

     On April 2, 1999 the Board of Directors approved the purchase of 10% of the
Company's outstanding common stock over the next 12 months. As of December 31,
1999 the Company had repurchased 4,323,050 shares of common stock at an
aggregate cost of $25.0 million.

ACQUISITIONS AND INVESTMENTS

     The Company acquired two companies in 1998 through a combination of $3.5
million in cash and the issuance of 194,497 shares of the Company's common
stock. The Company completed six acquisitions in 1997 through a combination of
cash totaling $15.1 million, the issuance of 12,514,000 shares of the Company's
common stock and the issuance of 533,000 stock options. The acquisitions
completed during 1998 and 1997 are described in Note 2 to the Company's
accompanying financial statements.

     In conjunction with these acquisitions the Company assigned personnel to
facilitate the integration of the acquired companies into the Company's
operations. As a result, certain payroll and associated costs (Integration
Activity Costs) directly related to integration activities are reflected as
restructuring and acquisition-related charges within the line titled, "Charge
for purchased in-process product development, write-off of software development
costs, restructuring, acquisition-related and other charges" in the consolidated
statements of operations for 1998 and 1997. These costs and their impact on
year-over-year comparisons are more fully explained in note 2 to the
consolidated financial statements and the following Results of Operations.


                                       19

<PAGE>   21



     During 1999 the Company became a one-third owner of GLINK, LLC (GLINK), a
joint venture established to develop an electronic marketplace for the grocery
industry. The Company accounts for its ownership in GLINK using the equity
method of accounting, which requires the Company to record its share of income
and losses of GLINK to the consolidated statements of operations under "Equity
in losses of joint ventures" in the period they occur.

     In the fourth quarter of 1999 the Company announced a substantial increase
in its investment in advertising, public relations, sales and technology in
order to enhance the awareness of its position as a supplier of e-commerce
enablement solutions in an expanding marketplace for business-to-business
e-commerce. The investments totaled approximately $3 million in the fourth
quarter of 1999, and are estimated to be about $25 million in 2000.

RESULTS OF OPERATIONS

     The following table presents, for the periods indicated, the percentage
relationship of consolidated statements of operations data items to total
revenues for the years ended December 31, 1999, 1998 and 1997:

1999 COMPARED TO 1998

     Revenues. Total revenues increased 15% to $155.5 million in 1999 from
$135.2 million in 1998. Revenues for services increased 23.4% to $108.7 million
in 1999 from $88.1 million in 1998. This increase is attributable to growth in
the Company's operations management and professional services, as well as growth
in transaction fees on harbinger.net.

     Revenues from software sales decreased 0.6% to $46.8 million in 1999 from
$47.1 million in 1998. In the fourth quarter of 1998, the Company phased out
about 40% of its product lines (collectively referred to as Sunset Products) and
discontinued relationships with certain third-party resellers of the Company's
software products. The decline in 1999 software sales is primarily attributable
to this phase-out. On a pro forma basis, software sales, net of Sunset Products
and discontinued third-party resellers, increased 24.3% to $40.8 million in 1999
from $32.9 million in 1998. The Company is in the process of upgrading its
products to accommodate public Internet data protocols and Windows functionality
and is actively migrating its customer base from old to new technology
platforms. Approximately 23% of software revenues were derived from these
migrations in 1999.

     Direct Costs. Direct costs for services increased to $46.4 million in 1999
from $34.5 million in 1998. As a percentage of service revenues, these costs
were 42.7% in 1999 and 39.2% in 1998. The increase in direct services costs as a
percentage of services revenues primarily reflects the effects of a higher
proportion of lower-margin professional enablement services revenues in 1999 and
the effect of reallocating personnel costs to Integration Activity Costs in
1998. Direct software costs increased to $4.6 million in 1999 from $3.7 million
in 1998. Direct software costs as a percentage of software revenues were 9.8% in
1999 and 7.9% in 1998. The increase in direct software costs as a percentage of
software revenues is primarily due to an increase in amortization of capitalized
software costs while software revenues remained relatively flat due to the
phase-out of Sunset Products.

     Selling and Marketing. Selling and marketing expenses increased 25% to
$39.6 million in 1999 from $31.6 million in 1998. As a percentage of revenues
these expenses were 25.4% in 1999 and 23.4% in 1998. The increase in selling and
marketing expenses as a percentage of revenues reflects an increase in sales
force personnel in 1999 and an incremental investment in marketing and brand
awareness for harbinger.net. In addition, the increase in 1999 is partially
attributable to the effect of reallocating personnel costs to Integration
Activity Costs in 1998.

     General and Administrative. General and administrative expenses decreased
4% to $31.0 million in 1999 from $32.2 million in 1998. As a percentage of
revenues these expenses were 19.9% in 1999 and 23.8% in 1998. Included in 1999
is a $3.3 million charge recorded in the fourth quarter for aged accounts
receivable, offset by $1.8 million in credits recorded in the first nine months
for recovery of outstanding royalty receivables from a specific customer that
had been reserved for in 1998. Included in 1998 is a $5.8 million net charge
recorded for outstanding royalty and accounts receivable from a reseller and
certain other customer accounts. Excluding the aforementioned net charges,
general and administrative expenses would have been $29.5 million or 18.9% of
revenues in 1999 and $26.4 million or 19.5% of revenues in 1998. The increase in
adjusted general and administrative expenses is primarily attributable to the
effect of reallocating personnel costs to Integration Activity Costs in 1998,
and increases in office space and investments in information technology in 1999.

     Depreciation and Amortization. Depreciation and amortization increased 18%
to $9.5 million in 1999 from $8.1 million in 1998. As a percentage of revenues
these expenses were 6.1% in 1999 and 6.0% in 1998. The increase in depreciation
and amortization is due to the purchase of computer hardware and software
associated with the Company's investment in its information technology
infrastructure during 1999 and the latter half of 1998.

     Product Development. Total expenditures for product development, including
capitalized software development costs, increased 24% to $17.6 million in 1999
from $14.1 million in 1998. Total expenses for product development increased 11%
to $11.8 million in 1999 from $10.6 million in 1998. As a percentage of revenues
total product development expenses decreased to 7.6% in 1999 from 7.9% in 1998.
The increase in product development expenses is primarily attributable to
increased development of Internet-based products, the 1999 addition of Harbinger
Labs, the Company's development group devoted to next generation product
development, and the effect of reallocating personnel costs to Integration
Activity Costs in 1998. The Company capitalized software development costs of
$5.8 million and $3.6 million in 1999 and 1998, respectively. In the third
quarter of 1999 the Company capitalized $1.6 million of development costs for
software that was originally being developed for internal use by the Company's
information technology group. Marketing and licensing efforts on this product
were initiated in the third quarter of 1999 and the first license of this
product was sold in the fourth quarter of 1999. Excluding this item, capitalized
software development costs were $4.2 million or 26.6% of total expenditures for
product development in 1999 and $3.6 million or 25.0% of product development in
1998. The increase in amounts capitalized reflects an increase in


                                       21

<PAGE>   23


development activities associated with products that have reached technological
feasibility. Amortization of capitalized software development costs included in
direct costs of software totaled $2.0 million and $1.6 million in 1999 and 1998,
respectively.

     Charge for Purchased In-Process Product Development, Write-off of Software
Development Costs, Restructuring, Acquisition-related and Other Charges
(Charges). The Company incurred Charges of $27.0 million in 1998 related to the
costs of integrating its acquisitions in 1998 and 1997 and its restructuring in
1998. Approximately $4.1 million in 1998 Charges were personnel costs
reallocated to Integration Activity Costs. The integration activities were
completed by the end of 1998 and the internal resources and their associated
costs are recorded in their original operating cost categories in 1999. (See
note 10 to the accompanying audited consolidated financial statements.)

     Income Taxes. The Company recorded income tax expense of $813,000 and
$705,000 in 1999 and 1998, respectively. Taxable income of $7.4 million will be
required in future years to realize the Company's net deferred income tax assets
at December 31, 1999 of $2.8 million, net of a valuation allowance. Future
decreases of $3.3 million in the total valuation allowance of $18.9 million at
December 31, 1999 relate to foreign net operating loss carryforwards and will
reduce the intangibles associated with those acquisitions as the net operating
loss carryforwards are realized.

     Discontinued Operations. The Company discontinued its TrustedLink
Procurement business (TLP) on September 30, 1998 and its TrustedLink Banker
division (Banker) on December 31, 1997, both of which had been generating lower
than desired profitability and growth and which management deemed to be no
longer strategic to the Company. The disposal of Banker was substantially
completed by December 31, 1998. During 1999 the Company recovered the remaining
loss reserve estimates associated with the disposal of Banker as contingencies
related with the disposal were resolved. The recovery of the reserve in 1999 for
Banker is reported in the accompanying consolidated statements of operations
under "Income (loss) on disposal of discontinued operations." At December 31,
1999 the Company had a remaining reserve of $3.3 million for TLP related to
certain remaining contingencies. (See note 11 to the accompanying audited
consolidated financial statements.)

         Net Income (Loss) and Earnings (Loss) Per Share. The Company realized
net income of $16.6 million or $0.41 per diluted share in 1999 and a net loss of
$14.7 million or $0.35 per diluted share in 1998. In order to facilitate
comparison of operating results year over year, the Company also presents its
earnings by adjusting for certain charges and tax-affecting the results at a 39%
effective rate (core earnings). A comparison of 1999 and 1998 is as follows:

     Core earnings declined in 1999 compared to 1998 primarily as a result of
the Company's investment in technology and marketing of the Company's e-commerce
portal, harbinger.net, in the first three quarters of 1999, as well as the
fourth quarter launch of its marketing and brand awareness campaign for the
Company as a whole. The Company expects to continue

                                       22

<PAGE>   24


this program in 2000 as well as increasing its sales force and enhancing its
technologies in order to position itself as a primary service provider to the
anticipated growing number of businesses seeking e-commerce solutions over the
next few years. As a result of these investments the Company expects a further
decline in core earnings in 2000.


1998 COMPARED TO 1997

     Revenues. Total revenues increased 14% to $135.2 million in 1998 from
$118.2 million in 1997. Revenues for services increased 38.9% to $88.1 million
from $63.4 million in 1997. This increase is partly attributable to acquisitions
made in 1998, and also reflects growth in transaction fees, professional
services and maintenance. Transaction fees increased as a result of an increase
in subscribers to the Company's VAN and IVAS networks, plus an increase in the
average transaction volume per customer each year. Software revenues decreased
14.1% to $47.1 million in 1998 from $54.8 million in 1997, primarily due to
decreased royalty revenues from resellers.

     Direct Costs. Direct costs for services increased to $34.5 million in 1998
from $22.7 million in 1997. As a percentage of service revenues these costs were
39.2% in 1998 and 35.8% in 1997. The increase in direct costs as a percentage of
service revenues is primarily attributable to a larger percentage of
lower-margin professional enablement services in 1998. The Company increased its
emphasis on enablement services in response to market demand for e-commerce
solutions integration. The increase in direct costs in 1998 compared to 1997 was
partially offset by the reallocation of personnel costs to Integration Activity
Costs in 1998. Direct software costs decreased to $3.7 million in 1998 from $7.8
million in 1997. Direct software costs as a percentage of software revenues were
7.9% in 1998 and 14.2% in 1997. The decrease in direct software costs is due to
decreased software amortization resulting from a write-off of capitalized and
purchased software development in connection with certain business combinations
in 1997 and a decrease in royalty and other fees paid by the Company to
third-party resellers in 1998.

     Selling and Marketing. Selling and marketing expenses increased 18% to
$31.6 million in 1998 from $26.7 million in 1997. As a percentage of revenues
these expenses were 23.4% in 1998 and 22.6% in 1997. The increase in selling and
marketing expenses as a percentage of revenues reflects an increase in sales and
marketing personnel and related selling costs offset by a decrease in
reallocated personnel costs to Integration Activity Costs.

     General and Administrative. General and administrative expenses increased
55% to $32.2 million in 1998 from $20.8 million in 1997. As a percentage of
revenues these expenses were 23.8% in 1998 and 17.6% in 1997. The increase in
general and administrative expenses is primarily due to a $5.8 million net
charge recorded for outstanding royalty and accounts receivable from a reseller
and certain other customer accounts. Excluding the impact of this net charge,
general and administrative expenses would have increased to $26.4 million or
19.5% of revenues for 1998. The increase in adjusted general and administrative
expenses as a percentage of revenues is attributable to an increase in personnel
and associated costs in both the Company's domestic and European operations, an
increase in rent for expanded office space, adjustments to compensation related
accruals and a decrease in personnel costs reallocated to Integration Activity
Costs in 1998 compared to 1997.

     Depreciation and Amortization. Depreciation and amortization increased 14%
to $8.1 million in 1998 from $7.1 million in 1997. As a percentage of revenues
these expenses remained the same. The increase in depreciation and amortization
is a result of additions to fixed assets and increased intangible assets
acquired through business combinations in 1998.

     Product Development. Total expenditures for product development, including
capitalized software development costs, decreased 30% to $14.1 million in 1998
from $20.3 million in 1997. Total expenses for product development decreased to
$10.6 million in 1998 from $15.3 million in 1997. As a percentage of revenues
total product development expenses decreased to 7.9% in 1998 from 12.9% in 1997.
The decrease in product development expenses is primarily attributable to
efficiencies gained in consolidating development resources of acquired
companies, and the impact of personnel costs reallocated to Integration Activity
Costs. The Company capitalized software development costs of $3.6 million and
$5.0 million in 1998 and 1997, respectively, which represented 25.0% and 24.7%
of total expenditures for product development in these respective periods. The
decrease in amounts capitalized reflects a decrease in development activities
associated with products that have reached technological feasibility.
Amortization of capitalized software development costs included in direct costs
of software totaled $1.6 million and $3.7 million in 1998 and 1997,
respectively.

     Charge for Purchased In-Process Product Development, Write-off of Software
Development Costs, Restructuring, Acquisition-related and Other Charges. The
Company incurred Charges of $27.0 million in 1998 and $40.6 million in 1997 as a
result of 15 acquisitions and two restructurings from 1996 to 1998.
Approximately $4.1 million in 1998 and $7.8 million in


                                       23

<PAGE>   25


1997 in Charges were personnel costs reallocated to Integration Activity Costs.
(See note 11 to the accompanying audited consolidated financial statements.)

     Income Taxes. The Company recorded income tax expense of $705,000 and $3.1
million in 1998 and 1997, respectively. 1998 tax expense decreased approximately
77% as compared with 1997. This is primarily due to profits in foreign taxing
jurisdictions in 1997 that could not be offset by domestic net operating losses.
Foreign tax expense was $1.2 million in 1997 as compared with a benefit of
$100,000 in 1998. 1997 tax expense also included deferred taxes of $1.1 million.
In 1998 there was no deferred tax expense because all deferred tax assets had
been fully reserved for with an allowance.

     Discontinued Operations. The Company discontinued TLP on September 30, 1998
and Banker on December 31, 1997, both of which had been generating lower than
desired profitability and growth and which management deemed to be no longer
strategic to the Company. The results of TLP and Banker for 1998 and 1997 are
reported in the accompanying reclassified audited consolidated statement of
operations under "Loss from operations of TrustedLink Procurement business and
TrustedLink Banker division." For Banker, the Company in 1997 provided for an
anticipated loss of $4.0 million related to the discontinuance of the division,
including an estimated $2.3 million for operating losses during the phase-out
period. As of December 31, 1998, the disposal of Banker was substantially
completed and $2.0 million in anticipated losses not incurred was recorded as a
reduction to "Income (loss) on disposal of TrustedLink Banker" on the statement
of operations in 1998.

     For TLP, the Company provided for an anticipated loss on the disposal of
the business of $6.4 million, including $2.9 million for operating losses during
the phase-out period. (See note 11 to the accompanying audited consolidated
financial statements.)

     Loss on Extinguishment of Debt. The Company recorded a loss of $2.4 million
on debt extinguishment in the first quarter of 1997 related to the acquisition
of Harbinger Net Services (HNS). (See note 2 to the accompanying audited
consolidated financial statements.)

     Net Loss and Loss Per Share. The Company realized net losses of $14.7
million or $0.35 per share in 1998 and $39.0 million or $1.02 per share in 1997.

     Core earnings increased in 1998 compared to 1997 primarily as a result of a
decrease in product development expenses in 1998 which was realized by
consolidating the development resources of acquired companies.

LIQUIDITY AND CAPITAL RESOURCES


                                       24

<PAGE>   26


     Cash and short-term investments decreased $19.3 million to $73.0 million at
December 31, 1999 compared to $92.3 million at December 31, 1998, primarily due
to 1999 stock repurchases totaling $17.6 million and a $17.2 million investment
in information technology and capitalized software, offset by $15.6 million of
positive cash flows from operations and exercises of options and warrants.

     Management expects the Company will continue to fund its operations,
investment needs and capital expenditures through cash flows generated from
operations, cash on hand, and additional equity and debt capital if necessary.
Several factors could have an impact on the Company's cash flow in the future,
including the effects of the Company's strategic investment in marketing and
sales and technology development, currently projected to be $25 million in
additional spending that will substantially be recorded to selling and marketing
expenses on the consolidated statement of operations in 2000. Additionally, the
Company recently announced the creation of a $25 million venture division
focused on investing in new vertical market portal opportunities in 2000. The
Company also anticipates continued liquidation of liabilities incurred due to
Charges and discontinued operations. Further, management is authorized to
repurchase additional Company stock if favorable pricing scenarios develop in
the future. Liquidity could also be negatively impacted as a result of a
shareholder class action lawsuit filed against the Company in 1999. Although the
outcome of this action cannot be determined at this time, management does not
believe the outcome will have a material adverse effect on the Company's
financial position.

     The Company does not believe that inflation has had a material impact on
its business, however, there can be no assurance that the Company's business
will not be affected by inflation in the future.

YEAR 2000 READINESS

     The Company spent considerable internal and external resources from 1997
through 1999 preparing for the "Year 2000" computer issue. The Year 2000 issue
relates to the ability of a computer system to properly process data beginning
on January 1, 2000. The Company's efforts were spent to ensure that its computer
products were "Year 2000 Ready," as defined, and that its internal core
information technology (IT) and non-IT systems were Year 2000 Ready.

     The Company believes it successfully implemented its Year 2000 program, as
evidenced by the continued successful operation of its computer products and
core internal IT and non-IT systems. The Company has not encountered any
significant problems with its third-party customers, financial institutions,
vendors and others with whom it conducts business. The Company will continue to
monitor its product performance and core IT and non-IT systems throughout 2000
to ensure ongoing performance. While there can be no assurance that no Year 2000
related issues will arise, as of December 31, 1999, the Company believes, based
on information currently available, that Year 2000-related events are not likely
to have a material effect on its results of operation, financial condition or
liquidity.

     The total pre-tax cost associated with Year 2000 modifications of the
Company's products was approximately $1 million to $2 million, funded from the
Company's internal operating cash flows. Such costs do not include costs for new
internal software or for modifications to existing internal software for the
Company's IT systems, as these projects were not accelerated due to the Year
2000 issue.

EURO CONVERSION

     Effective January 1, 1999, 11 of the 15 member countries of the European
Union adopted a single European currency, the euro, as their common legal
currency. Like many companies that operate in Europe, various aspects of the
Company's business were affected by the conversion to the euro. The Company has
not experienced any significant impact in its internal IT systems or its
customer products as a result of the euro conversion.


QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

     The Company has not entered into any transactions using derivative
financial instruments or derivative commodity instruments and believes its
exposure to interest rate risk, foreign currency exchange rate risk and other
relevant market risks is not material.

assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

         REVENUE RECOGNITION

         Services

         Revenues for services principally include subscription fees for
transactions on harbinger.net, the Company's e-commerce portal; software
maintenance; and professional service fees for outsourcing, training and
e-commerce enablement. Subscription fees are a combination of monthly access
charges and transaction-based usage charges and are recognized as incurred each
month. Software maintenance is billed in advance with revenue deferred and
recognized ratably over the one-year service period. Revenues for professional
services are based on actual services rendered and are recognized as services
are performed.

         Software

         The Company recognizes revenue in accordance with Statement of Position
(SOP) 97-2, Software Revenue Recognition, and SOP 98-4, Deferral of the
Effective Date of a Provision of SOP 97-2. Revenue is derived from the sale of
software licenses, hardware and software services and is allocated to each
element of the arrangement based on the relative fair values of the elements
established by the price charged when the respective element is sold separately.

         Revenues derived from software license fees are recognized upon
shipment, net of estimated returns. Software revenues also include royalties due
to the Company under distribution agreements with third parties that are
recognized either on shipment of software to a distributor or upon sales to end
users by a distributor, depending on the terms of the distribution agreement.

         In December 1998 the Accounting Standards Committee of the American
Institute of Certified Public Accountants issued SOP 98-9, Software Revenue
Recognition with Respect to Certain Transactions. SOP 98-9 is effective for
fiscal years beginning after March 15, 1999 and the Company does not expect a
material change to its accounting for revenues as a result of adopting the
provisions of SOP 98-9.

         Deferred Revenues

         Deferred revenues represent payments received from customers or
billings invoiced to customers for software and services billed in advance of
revenue recognition.



                                       67

         DIRECT COSTS

         Direct costs for services include network asset depreciation and
amortization, telecommunications charges and the costs of personnel to manage
network operations, customer support, professional service engagements and
consulting. Direct costs for software include duplication, packaging and
shipping of software, amortization of purchased technology and software
development costs and royalties paid to third-party distributors.

         CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

         Cash, cash equivalents and short-term investments are stated at cost,
which approximates fair value, and consist primarily of money market funds and
U.S. Treasury bills. The Company considers all highly liquid investments with
original maturities of three months or less to be cash equivalents. Investments
maturing between three and 12 months from the date of purchase are classified as
short-term investments.

         Management determines the appropriate classification of debt securities
at the time of purchase and re-evaluates such designations quarterly. As of
December 31, 1999 debt securities were classified as held-to-maturity as the
Company intended to hold, and had the ability to hold, these securities to
maturity. Held-to-maturity securities are stated at amortized cost, which
approximates fair market value.

         Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of temporary cash investments
and other short-term obligations of the U.S. Government.

         PROPERTY AND EQUIPMENT

         Property and equipment are stated at cost, less accumulated
depreciation and amortization. Depreciation and amortization are provided using
the straight-line method over the estimated useful lives of the assets,
generally three to 10 years. Leasehold improvements are amortized straight-line
over the shorter of the lease or estimated useful life of the asset.

         NONMONETARY TRANSACTION

         The Company accounts for nonmonetary transactions based on the fair
value of the assets or services involved. During 1999 the Company acquired
software to use in its internal purchasing system as part of its overall ERP
project in exchange for certain Company software products that the acquiring
company used internally. The fair value, based on a combination of market
comparables, competitive bids and prior sales histories, was $330,000. This
value was recorded as property and equipment on the consolidated balance sheets
and as software revenue on the consolidated statements of operations.

         INVESTMENTS IN JOINT VENTURES

         During 1999 the Company became one-third owner of GLINK, LLC (GLINK), a
joint venture established to develop an electronic marketplace for the grocery
industry. The Company accounts for its ownership in GLINK using the equity
method of accounting, which requires the Company to record its share of income
and losses of GLINK to the consolidated statements of operations under "Equity
in losses of joint ventures" in the period they occur. The Company also applied
the equity method of accounting for its holdings in other immaterial joint
ventures in 1997 that have since been dissolved.

         INTANGIBLE ASSETS

         Purchased Technology, Goodwill and Other Intangible Assets

         Purchased technology, goodwill and other intangible assets are
amortized on a straight-line basis over the expected periods to be benefited,
generally five to 10 years. The Company evaluates the recoverability of these
intangible assets at each period end using the undiscounted estimated future net
operating cash flows expected to be derived from such assets. If such evaluation
indicates a potential impairment, the Company uses the fair value to determine
the amount of these intangible assets that should be written off.


                                       68
<PAGE>   42

         Software Development Costs

         The Company capitalizes certain software development costs in
accordance with Statement of Financial Accounting Standards (SFAS) No. 86,
Accounting for the Costs of Computer Software to Be Sold, Leased or Otherwise
Marketed. Costs incurred internally to create a computer software product or to
develop an enhancement to an existing product are charged to expense when
incurred as research and development until technological feasibility has been
established for the product or enhancement. Thereafter, all software production
costs are capitalized and reported at the lower of unamortized cost or net
realizable value. Capitalization ceases when the product or enhancement is
available for general release to customers. Software development costs are
amortized on a product-by-product basis at the greater of the amounts computed
using (a) the ratio of current gross revenues for a product or enhancement to
the total current and anticipated future gross revenues for that product or
enhancement, or (b) the straight-line method over the remaining estimated
economic life of the product or enhancement, not to exceed five years. The
Company evaluates the net realizable value of its software development costs at
each period end using undiscounted estimated future net operating cash flows
expected to be derived from the respective software product or enhancement. If
such evaluation indicates that the unamortized software development costs exceed
the net realizable value, such amount is written off.

         INCOME TAXES

         The Company accounts for income taxes using the asset and liability
method of SFAS No. 109, Accounting for Income Taxes. Under SFAS No. 109 deferred
income tax assets and liabilities are recognized for the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases. Deferred income
tax assets and liabilities are measured using enacted tax rates expected to
apply to taxable income in the years in which those temporary differences are
expected to be recovered or settled. The effect on deferred income tax assets
and liabilities of a change in tax rates is recognized in income in the period
that includes the enactment date.

         RECLASSIFICATIONS

         Certain reclassifications have been made to the 1998 and 1997
consolidated financial statements to conform with the 1999 presentation.

         FAIR VALUE OF FINANCIAL INSTRUMENTS

         The Company uses financial instruments in the normal course of its
business. The carrying values of cash equivalents, short-term investments,
accounts and royalties receivable, accounts payable, accrued expenses and
deferred revenues approximate fair value due to the short-term maturities of
these assets and liabilities.

         FOREIGN CURRENCY TRANSLATION

         Assets and liabilities of the Company's international operations are
translated into U.S. dollars at current exchange rates while the related
statements of operations are translated at average exchange rates during each
quarterly reporting period. Net exchange gains or losses resulting from the
translation of assets and liabilities are recorded as cumulative foreign
currency translation adjustments and reported in the consolidated statements of
comprehensive income (loss).

         STOCK COMPENSATION PLANS

         The Company applies the intrinsic-value-based method of accounting for
its nonvariable stock option plans in accordance with the provisions of
Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to
Employees (APB Opinion No. 25), and related interpretations. As such,
compensation expense would generally be recorded on the date of grant only if
the current market price of the underlying stock exceeded the exercise price.

2.       ACQUISITIONS AND INVESTMENTS

         1999 INVESTMENT

         GLINK

          The Company became one-third owner of GLINK, a joint venture
established to develop an electronic marketplace for the grocery industry. The
Company made an initial $300,000 cash investment, which was recorded in "Other
assets" on the consolidated balance sheets (see note 13) .

         1998 ACQUISITIONS

         EDI Works! LLC (EDI Works!)

         Effective March 31, 1998 the Company acquired EDI Works!, a Texas
limited liability company, for 194,497 shares of the Company's common stock in a
transaction accounted for using the pooling-of-interests method of accounting.
The EDI Works! business combination is not material, and therefore has been
accounted for as an immaterial pooling, with the accumulated earnings of EDI
Works! of $129,000 being added directly to the Company's accumulated deficit on
the date of acquisition. The results of operations of EDI Works! are included in
the Company's consolidated statements of operations for the year ended December
31, 1998. In connection with the EDI Works! acquisition the Company recorded a
charge of $805,000 for acquisition-related expenses, asset write-downs and
integration costs (see note 10).

         MACTEC, Inc. (MACTEC)

         Effective July 9, 1998 the Company acquired substantially all of the
assets of the Materials Management Division of MACTEC, located in Tulsa,
Oklahoma, for approximately $3.5 million in cash. The Company recorded the
acquisition using the purchase method of accounting, with approximately $3.5
million recorded to goodwill in 1998 and an additional $128,000 recorded to
goodwill in 1999. The goodwill will be amortized ratably over 10 years.

         1997 ACQUISITIONS

         SupplyTech, Inc. (STI)

         On January 3, 1997 the Company acquired STI for 3,600,000 unregistered
shares of the Company's common stock in a transaction accounted for using the
pooling-of-interests method of accounting. Effective January 3, 1997 the results
of operations of the Company and STI were retroactively combined. In connection
with the STI acquisition, the Company incurred a charge of $12.4 million for
acquisition-related expenses, asset write-downs and integration costs incurred
(including a $3.2 million charge for the vesting of a contingent option which
became exercisable upon the closing of the merger) (see note 10). The Company
recorded a net deferred income tax asset during the first quarter of 1997 of
$1.8 million relating to the STI acquisition and provided a valuation allowance
against such net deferred income tax asset to reduce it to zero.

         Premenos Technology Corp. (Premenos)

         On December 19, 1997 the Company acquired Premenos, a Delaware
corporation based in Concord, California. In connection with the transaction,
which was accounted for using the pooling-of-interests method of accounting, the
Company issued 8,037,982 shares of its common stock in exchange for all of the
shares of Premenos common stock. All Premenos options and warrants were
converted into the Company's options and warrants in accordance with the
conversion ratio. In connection with the Premenos acquisition, the Company
incurred charges for acquisition-related expenses, asset write downs and
integration costs of $13.7 million in 1998 and $15.3 million in 1997 (see note
10).

         The financial position and results of operations of the Company have
been restated for all periods presented to give retroactive effect to the
Premenos acquisition. Total revenues and net income (loss) for the Company and
Premenos as previously reported are as follows (in thousands):

</TABLE>


         On September 30, 1998 the Company discontinued its TrustedLink
Procurement business (TLP) and on December 31, 1997 the Company discontinued its
TrustedLink Banker division (Banker). The revenues of Harbinger Corporation
reported above have been restated accordingly (see note 11).

         Harbinger Net Services (HNS)

         On January 1, 1997 the Company exercised its rights as majority
shareholder of HNS to appoint a majority of the members of the HNS Board of
Managers. As a result, effective January 1, 1997 the Company began accounting
for its investment in HNS by consolidating the balance sheets and statements of
operations of HNS with those of the Company. Prior to the January 1, 1997
acquisition date the Company accounted for its investment in HNS using the
equity method of accounting.

         Also on January 1, 1997 the Company entered into a debenture purchase
agreement with the holder of the debenture whereby the Company acquired the
debenture in exchange for $1.5 million in cash and 363,432 shares of the
Company's common stock valued at $4.2 million. The Company recorded an
extraordinary loss on debt extinguishment of $2.4 million in the first quarter
of 1997 related to this transaction.

         Immediately after this transaction the Company acquired the remaining
minority interest in HNS, consisting of 585,335 shares of HNS common stock and
stock options to acquire 564,727 shares of HNS common stock at exercise prices
ranging from $0.70 per share to $1.65 per share, by exchanging cash of $1.6
million and stock options to acquire 532,975 shares of the Company's common
stock at exercise prices ranging from $10.14 per share to $11.02 per share which
were valued at $2.2 million. Including transaction and other costs of $350,000,
the Company paid $4.1 million for the acquisition of the HNS minority interest
which was accounted for using the purchase method of accounting, with $2.7
million of the purchase price allocated to in-process product development and
charged to the consolidated statement of operations on January 1, 1997, and $1.4
million allocated to goodwill and purchased technology. The Company also
incurred acquisition-related expenses and asset write-downs related to this
acquisition of $2.0 million in 1997 (see note 10). The Company recorded a net
deferred income tax asset of approximately $840,000 as a result of this
acquisition and provided a valuation allowance against such net deferred income
tax asset to reduce it to zero.

         Smart Solutions for Electronic Commerce, Inc. (Smart Solutions)

         Effective May 1, 1997 the Company acquired all of the common stock of
Smart Solutions, a Michigan corporation based in Traverse City, Michigan, for
$677,000, consisting of 29,635 unregistered shares of the Company's common stock
valued at $454,000 and the assumption of $223,000 in liabilities. The Company
recorded the acquisition using the purchase method of accounting with $100,000
of the purchase price allocated to purchased technology, $71,000 allocated to
tangible assets and $506,000 allocated to goodwill.


                                       71

         Acquion, Inc. (Acquion)

         Effective August 22, 1997 the Company acquired all of the common stock
of Acquion, a California corporation based in Greenville, South Carolina, for
approximately $13.6 million, consisting of $12.0 million in cash and the
assumption of approximately $1.6 million in liabilities including transaction
costs. The Company recorded the acquisition using the purchase method of
accounting with $10.9 million of the purchase price allocated to in-process
product development and charged to the consolidated statement of operations in
1997, $641,000 allocated to purchased technology and $2.0 million allocated to
goodwill. The Company also incurred acquisition-related expenses and asset write
downs of $2.5 million during 1997 related to this acquisition (see note 10). The
Company recorded a net deferred income tax asset of approximately $4.1 million
as a result of this acquisition and provided a valuation allowance against such
net deferred income tax asset to reduce it to zero. TLP, a separate business
within Acquion, was discontinued by the Company on September 30, 1998 (see note
11).

         Atlas Products International, Limited (Atlas)

         Effective October 23, 1997 the Company acquired Atlas, a company
organized under the laws of England, based in Manchester, United Kingdom, for
467,098 unregistered shares of the Company's common stock in a transaction
accounted for using the pooling-of-interests method of accounting. In connection
with the acquisition the Company recorded charges for acquisition-related
expenses, asset write downs and integration costs incurred of $1.4 million in
1998 and $2.0 million in 1997, respectively (see note 10). The Atlas business
combination was not material, and therefore was accounted for as an immaterial
pooling, with Atlas' accumulated deficit of $296,000 being credited directly to
the Company's accumulated deficit on the date of acquisition.

PRO FORMA FINANCIAL INFORMATION

         The results of operations of the acquired companies have been included
in the Company's consolidated statements of operations beginning on the
following dates: EDI Works!: March 31, 1998; MACTEC: July 9, 1998; HNS: January
1, 1997; Smart Solutions: May 1, 1997; Acquion: August 22, 1997; and Atlas:
October 1, 1997.

         Unaudited pro forma results of operations of the Company for 1998 would
not be materially different as a result of the 1998 acquisitions of EDI Works!
and MACTEC and are therefore not presented for 1998.


3.       PURCHASED TECHNOLOGY AND DISTRIBUTION AGREEMENTS

         System Software Associates, Inc. (SSA)

         On May 26, 1999 the Company executed an agreement (the Agreement) with
SSA terminating its distributor arrangement that had existed since 1995. Under
the Agreement, SSA paid the Company a total of approximately $2.0 million in
settlement of certain royalty receivables, maintenance services provided to
SSA's customers by the Company from 1995 through 1999 and an additional license
of source code provided to SSA. The settlement proceeds were allocated pro-rata
to the three components of the Agreement based on their relative fair values.
The following credits were recorded to the Company's accompanying consolidated
statement of operations in 1999: $1.0 million to general and administrative
costs for collection of accounts that had been reserved for in 1998, $628,000 to
direct costs of services for reimbursement of maintenance costs, and $420,000 to
software revenue for license of source code.

         At December 31, 1998 the Company had a net provision of $3.6 million in
its allowance for doubtful accounts related to royalty receivables due from SSA.

         On July 21, 1995 the Company entered into a distribution agreement and
purchased certain software products from SSA in exchange for the issuance of
1,237,500 shares of the Company's common stock valued at $4.7 million at the
date of issuance and the issuance of 4,000,000 shares of the Company's zero
coupon redeemable preferred stock (see note 8). The Company allocated the
consideration associated with these transactions of $4.8 million (including
transaction costs of $122,000) as follows: $2.3 million to purchased technology
and $2.5 million to the distribution agreement based upon the estimated fair
values of the purchased technology and distribution agreement at the date of the
exchange. During 1997 the purchased technology was written down due to the
acquisition of other replacement technology that was licensed to SSA. In


                                       72
<PAGE>   46

1998 the intangible asset associated with the distribution agreement was written
off based upon estimated future net cash flows from the arrangement (see note
10).

         General Electric Information Services, Inc. (GEIS)

         On September 30, 1999 the Company entered into an agreement with GEIS
that terminated all prior existing arrangements between the Company and GEIS
relating to GEIS' distribution and support of a certain product. As part of the
1999 agreement GEIS paid the Company $665,000 for the license of certain object
and source codes.

         On December 31, 1995 the Company entered into an alliance agreement
with GEIS and an agreement to purchase certain software products from GEIS. The
total purchase price was $2.5 million, consisting of $300,000 in cash and the
assumption of a note payable to GEIS in the amount of $2.2 million. The Company
recorded the purchase of the technology and the alliance agreement based upon
fair value with $1.2 million of the purchase price allocated to in-process
product development and charged to the consolidated statement of operations in
1995, $375,000 allocated to purchased technology, $950,000 allocated to the
alliance agreement, and $15,000 allocated to tangible assets. During 1997 the
purchased technology was written down due to the acquisition of other
replacement technology that was licensed to GEIS and the distribution agreement
was written down based upon future expectations of net cash flows from the
arrangement (see note 10).

         Certain terms of the alliance agreement include the referral of
customers to the Company by GEIS, the performance of certain software
maintenance services by GEIS and a $1.2 million guaranteed payment by GEIS to
the Company for the two-year period ended December 31, 1997, relating to
software maintenance revenues to be paid by GEIS to the Company. GEIS'
subsequent sales to end-users exceeded the $1.2 million guaranteed payment each
year.

         Distribution Agreement

         On February 5, 2000 the Company entered into an agreement with an
existing distributor whereby the distributor agreed to pay $1.2 million to the
Company for royalties owed from prior agreements dating back to 1992. This
amount was recorded as software revenues in the fourth quarter of 1999 in the
accompanying consolidated statements of operations.

         The Company's income taxes currently payable for federal and state
purposes have been reduced by the tax benefit derived from stock option
transactions. The benefit, which totaled $498,000 for the year ended December
31, 1997, has been credited directly to stockholders' equity.

         There is no income tax expense or benefit for discontinued operations
of TLP (from operations) in 1999 and 1998. There was no income tax expense for
discontinued operations of Banker (from operations) in 1997. There was no income
tax expense or benefit relating to loss on disposal of TLP or Banker or
extraordinary loss on debt extinguishment.

</TABLE>

         During 1999 the net decrease in the valuation allowance was $5.1
million. During 1998 the net increase in the valuation allowance was $2.8
million. A valuation allowance is established to reduce the deferred income tax
assets to the level at which it is "more likely than not" that the tax benefits
will be realized. Realization of tax benefits of deductible temporary
differences and operating loss and tax credit carryforwards depends on having
sufficient taxable income within the carryback and carryforward periods. Sources
of taxable income that may allow for the realization of tax benefits include:
(a) taxable income in the current year or prior years that is available through
carryback, (b) future taxable income that will result from the reversal of
existing taxable temporary differences, and (c) future taxable income generated
by future operations. The Company


                                       76
<PAGE>   50

continually reviews the adequacy of the valuation allowance and recognizes these
benefits as reassessment indicates that it is more likely than not that the
benefits will be realized.

         The Company acquired net operating losses and research tax credit
carryforwards in the 1997 Premenos acquisition (see note 2) of approximately
$1.3 million and $1.7 million, respectively. The utilization of these net
operating loss and research tax credit carryforwards is restricted, based on the
ability of Premenos as a separate company to generate taxable income.

         At December 31, 1999 the Company had domestic and foreign net operating
loss carryforwards and research tax credit carryforwards of approximately $48.0
million, $11.8 million and $1.5 million, respectively. The domestic net
operating loss carryforwards expire at various dates through 2021 unless
utilized. The foreign net operating loss carryforwards do not expire and the
research tax credit carryforwards expire beginning in 2007 through 2012. The
Company's domestic net operating loss carryforwards at December 31, 1999 include
$30.5 million in income tax deductions related to stock options excluded from
the table of deferred income tax assets above, which will be reflected as a
credit to additional paid-in capital when realized.

8.       REDEEMABLE PREFERRED STOCK

         In 1995 the Company issued 4,000,000 shares of zero coupon redeemable
preferred stock to SSA. The zero coupon redeemable preferred stock issued had no
voting or dividend rights, vested at a rate of 1,000,000 shares per year only if
SSA attained certain royalty targets for the years 1997 through 2000, and
contained mandatory redemption provisions of $0.67 per share payable in cash or
the Company's common stock, at the option of the holder, 30 days after the end
of each year. The royalty targets for 1998 and 1997 were not met and 2,000,000
of the shares of the zero coupon redeemable preferred stock were forfeited by
December 31, 1998. The remaining 2,000,000 shares were terminated in 1999 per
the terms of an agreement executed between the Company and SSA on May 26, 1999
that dissolved the distributor relationship (see note 3).

9.   SHAREHOLDERS' EQUITY

         PREFERRED STOCK

         The Board of Directors is authorized, subject to certain limitations
prescribed by law, without further shareholder approval, to issue from time to
time up to an aggregate of 20,000,000 shares of preferred stock in one or more
series and to fix or alter the designations, preferences, rights and any
qualifications, limitations or restrictions on the shares of each such series
thereof, including the dividend rights, dividend rates, conversion rights,
voting rights, terms of redemption (including sinking fund provisions),
redemption price or prices, liquidation preferences and the number of shares
constituting any series or designations of such series. As of December 31, 1999
there were no shares of redeemable preferred stock issued and outstanding.

         COMMON STOCK

         On April 24, 1998 the Board of Directors declared a three-for-two stock
split in the form of a stock dividend on the Company's common stock paid on May
15, 1998 to shareholders of record on May 1, 1998. All share, per share and
shareholders' equity amounts included in the Company's consolidated financial
statements have been restated to reflect the split for all periods presented.

         WARRANTS

         The Company issued warrants in December 1997 related to the acquisition
of Premenos. The warrants enable the holders to acquire 26,199 shares of the
Company's common stock at $5.63 per share, representing the exchange ratio
agreed to in the merger agreement. As of December 31, 1999, 25,913 warrants were
exercised and 286 warrants were cancelled, leaving no warrants outstanding.

         The Company issued warrants in April 1996 related to the acquisition of
NTEX and INOVIS. The warrants enable the holders to acquire 73,125 shares of the
Company's common stock at a range of $7.55 to $7.61 per share, representing the
fair value of the common stock at the date of issuance. There were 20,000
warrants outstanding as of December 31, 1999, all at an exercise price of $7.61.

         Stock Options

         The Company's 1989 Stock Option Plan (the 1989 Plan) and 1996 Stock
Option Plan (the 1996 Plan), together combined (the Plans), provide for the
grant of options to officers, directors, consultants and key employees. The 1996
Plan was amended in 1998 to add 1,050,000 options available for grant. The
maximum number of shares of stock that may be issued under the 1996 Plan may not
exceed the sum of 8,737,500 plus an amount equal to the number of all shares
that are either not subject to options granted under the 1989 Plan or were
subject to options granted thereunder that expire without exercise to officers,
directors, consultants and key employees. There were 1,044,628 options available
for grant at December 31, 1999. Options granted under the terms of the 1996 Plan
generally vest ratably over four years and are granted with an exercise price no
less than the fair market value of the common stock on the grant date. Options
granted prior to July 1994 vested ratably over three years and options granted
since July 1994 vest ratably over four years. All options granted expire seven
years from the date of grant. At December 31, 1999 there were options
outstanding to purchase 6,373,845 shares of the Company's common stock, of which
options to purchase 2,358,682 shares were exercisable. In 1998 the Board of
Directors authorized a repricing of certain unexercised employee stock options
held by employees other than certain senior executive officers. The number of
shares repriced to $6.91 was approximately 2.6 million. The four-year vesting
period for all repriced shares began in October 1998.

         In 1993 the Board of Directors authorized the creation of a stock
option plan for nonemployee members of the Company's Board of Directors (the
Nonemployee Directors Plan). The Nonemployee Directors Plan was amended in 1998
to add 187,500 options, for a total of 525,000 shares of common stock reserved
for issuance under the Nonemployee Directors Plan at an option price no less
than the fair market value of the common stock on the option grant date. Options
expire seven years from the date of grant. The options granted under the
Nonemployee Directors Plan vest ratably in the year of grant based on attendance
at regularly scheduled board meetings. Options which have not vested in the year
of grant expire and become available for grant under the Nonemployee Directors
Plan. At December 31, 1999 there were options outstanding and exercisable to
purchase 372,749 shares of the Company's common stock and 57,939 options
available to grant.

         In addition to outstanding options granted under the Plans and
Nonemployee Directors Plan, the Company has granted options to acquire 157,500
shares of common stock to certain existing and former nonemployee directors for
past services. As of December 31, 1999, all of these options had been exercised.

         At December 31, 1999 the Company had five stock-based compensation
plans which are described herein. The Company applies APB Opinion No. 25 and
related interpretations in accounting for its plans. Accordingly, no
compensation cost has been recognized for its nonvariable stock option plans and
its stock purchase plan. Had compensation cost for the Company's five
stock-based compensation plans been determined in accordance with SFAS No. 123,
Accounting for Stock-Based Compensation, the Company's net income (loss) and
income (loss) per share would have been the pro forma amounts indicated below
(in thousands, except per share data):

         The fair value of each option grant is estimated on the date of grant
using the Black-Scholes option-pricing model with the following assumptions:
1999: dividend yield of 0.5%, expected volatility of 92.9%, risk-free interest
rate of 6.17% and expected lives of five years for all the Plan options; 1998:
dividend yield of 0.5%, expected volatility of 82.6%, risk-free interest rate of
5.3% and expected lives of five years for all of the Plan options; 1997:
dividend yield of 0.5%, expected volatility of 67.3%, risk-free interest rate of
5.7% and expected lives of five years for all of the Plan options.

         Employee Stock Purchase Plan

         The Company offers employees the right to purchase shares of the
Company's common stock at 85% of the market price, as defined, pursuant to the
Employee Stock Purchase Plan (the Purchase Plan). Under the Purchase Plan,
full-time employees, except persons owning 5% or more of the Company's common
stock, are eligible to participate after six months of employment. Employees may
contribute up to 15% of their annual salary toward the Purchase Plan up to a
maximum of $15,000 per year. A maximum of 487,500 shares of common stock are
reserved for issuance under the Purchase Plan. During the years ended December
31, 1999, 1998 and 1997 shares issued under the Purchase Plan were 96,000,
89,247 and 160,813,


                                       80
<PAGE>   54

respectively. A portion of the shares issued in 1997 disclosed above was
authorized under existing purchase plans of acquired companies and is excluded
from the calculation of shares available to issue under the Purchase Plan.

         Under SFAS No. 123, compensation cost is disclosed for the fair value
of the employees' purchase rights, which was estimated using the Black-Scholes
model with the following assumptions for 1999: dividend yield of 0.5%, expected
volatility of 92.9% and risk-free interest rate of 6.17%; 1998: dividend yield
of 0.5%, expected volatility of 82.6%, and risk-free interest rate of 5.3%; and
for 1997: dividend yield of 0.5%, expected volatility of 67.3% and risk-free
interest rate of 5.7%. The expected life of the employees' purchase rights was
three months for all years. The weighted average fair value of those purchase
rights granted in 1999, 1998 and 1997 was $10.32, $7.11 and $5.95, respectively.
The impact of the Purchase Plan on the Company's pro forma net income (loss) and
income (loss) per share presentation required per SFAS No. 123 has been included
in Stock Options above.


10       CHARGE FOR PURCHASED IN-PROCESS PRODUCT DEVELOPMENT, WRITE-OFF OF
         SOFTWARE DEVELOPMENT COSTS, RESTRUCTURING, ACQUISITION-RELATED
         AND OTHER CHARGES

         In connection with acquisitions and restructurings in 1998 and 1997,
the Company incurred charges for purchased in-process product development,
write-off of software development costs, restructuring, acquisition-related and
other charges (Charges). A summary of the components, as adjusted for
discontinued TLP, are as follows (in thousands):

</TABLE>


         Integration costs associated with business combinations include costs
incurred for cross training, planning, product integration and marketing. For
1998 and 1997 approximately $4.1 million and $7.8 million of integration costs,
respectively, resulted from the redirection of internal resources and their
associated costs (Integration Activity Costs) to manage integration activities.
At December 31, 1999 the accrued liabilities related to the Charges were
approximately $3.0 million, compared to $7.5 million at December 31, 1998 (see
note 6). The reduction to accrued liabilities in 1999 was all due to cash
payments made. The liabilities at December 31, 1999 consist primarily of
reserves for lease terminations, severance costs and legal fees. The remaining
liabilities involve management estimates and the actual results could vary from
these estimates.

         Charges for in-process product development are recorded as a result of
acquiring research and development efforts through business combinations that,
at the date of acquisition, have not yet generated commercializable products and
have no alternative future use. The valuations for such purchased in-process
product developments are made with the assistance of third-party experts based
on fair value. Intangible asset write downs consist primarily of capitalized
software and goodwill that have become impaired as a result of product
phase-outs.

11.  DISCONTINUED OPERATIONS

         The Company discontinued TLP on September 30, 1998 and established a
$6.4 million reserve for the estimated loss on disposal of TLP, including $2.9
million for anticipated operating losses during the phase-out period. In the
second quarter of 1999 the Company sold the intangible assets and certain
property and equipment of TLP for $1.3 million, comprised of cash of $500,000
and a note receivable of $800,000. The resulting loss on disposal of TLP was
$2.0 million. Repayment on the note will occur at the earlier of the buyer
achieving certain sales targets or December 31, 2000.

                                       81
<PAGE>   55

         At December 31, 1999, the remaining balance in the loss reserve was
$3.3 million, available for certain remaining contingencies associated with the
disposal of TLP. Such contingencies primarily relate to lease termination costs,
customer transition issues and collection risks associated with notes and
accounts receivable. Management presently does not have an estimate on when
these final contingencies will settle.

         The operating loss during the phase-out period from the measurement
date of September 30, 1998 to December 31, 1999 was $1.2 million.

         The results of operations for TLP for 1998 and 1997 are reported in the
accompanying reclassified statements of operations under "Loss from operations
of TrustedLink Procurement business and TrustedLink Banker division". Revenues
from TLP for the years ended December 31, 1998 and 1997 were $2.9 million and
$2.5 million, respectively. No income tax benefit was recognized in 1998 or 1997
due to the Company's net operating loss carryforwards.

         The assets and liabilities of TLP are included in the Company's
consolidated balance sheets as of December 31, 1999 and 1998 and are summarized
as follows (in thousands):

         In the fourth quarter of 1997 the Board of Directors approved the
discontinuance of Banker. Revenues from Banker were $4.0 million for the year
ended December 31, 1997. The results of operations for Banker for all years
presented are reported in the accompanying reclassified statements of operations
under "Loss from operations of TrustedLink Procurement business and TrustedLink
Banker division". In the fourth quarter of 1997 the Company established a $4.0
million reserve for the estimated loss on disposal of Banker, including $2.3
million for anticipated operating losses during the phase-out period. No income
tax expense or benefit was recognized in 1997 due to the Company's net operating
loss carryforwards. As of December 31, 1998 the disposal of Banker was
substantially completed and $2.0 million in estimated losses not incurred was
recorded as a reduction to "Loss on disposal of TrustedLink Banker" on the
statement of operations. During 1999 the remaining contingencies associated with
Banker were settled and $1.4 million in estimated losses not incurred was
recorded as a reduction to "Loss on disposal of TrustedLink Banker" in 1999. The
operating loss of Banker during 1998 was $280,000. The assets and liabilities of
Banker included in the Company's consolidated balance sheets were immaterial at
December 31, 1999 and 1998.

statements of operations for the years ended December 31, 1999, 1998 and 1997 is

</TABLE>

     Options to purchase l.6 million shares of common stock outstanding during
1999 were excluded from the computation of diluted earnings per share because
the options' exercise price was greater than the average market price of the
common shares, and therefore, the effect would be antidilutive.

     Options to purchase 4.4 million and 3.0 million shares of common stock
outstanding during 1998 and 1997, respectively, were excluded from the
computation of diluted earnings per share due to their antidilutive effect as a
result of the Company's loss from continuing operations in those years.

13.  OTHER RELATED PARTY TRANSACTIONS

         During 1999 the Company became one-third owner of GLINK, which licensed
certain Company software for $250,000 and contracted for $252,000 in
professional services for which the Company received a 12-month note receivable
that matures on September 30, 2000. One-third of the aforementioned revenues
were eliminated in consolidation. Additionally, the Company provided $80,000 in
consulting services to GLINK in 1999 that was recorded as work-in-process and
deferred revenue on the accompanying consolidated balance sheets because payment
terms by GLINK had not been finalized (see note 2).

         The Company received notes receivable during the first quarter of 1999
totaling $605,000 from five employees who were former shareholders of EDI
Works!. The terms of the full-recourse notes are 18 months with an annual
interest rate of 8.75%. Interest accrues on a monthly basis with principal and
interest due at the end of the term of the notes. At December 31, 1999 four of
the notes, including interest, were paid in full to the Company resulting in a
remaining balance of principal and interest of $135,000.

         The Company received $40,000, $284,000 and $465,000 in 1999, 1998 and
1997, respectively, in revenue from an affiliated company that is partially
owned by an employee of one of the Company's foreign subsidiaries. This same
affiliated company also billed the Company $22,000, $189,000 and $63,000 in
1999, 1998 and 1997, respectively, for services.

                                       83

<PAGE>   57

         The Company has a note receivable of $50,000 from a former executive
officer with an annual interest rate of 9%, renewable at the end of each year.
At December 31, 1999 this note was fully reserved, as it is anticipated this
debt will be forgiven as part of a severance agreement (see note 6).

         Prior to the acquisition of Premenos, one of Premenos' directors was a
partner of a law firm that provided various legal services to Premenos. Two
other directors of Premenos also provided training and consulting services to
the Company from time to time. Amounts incurred for all such services in 1997
were $493,000.

14.      SEGMENT INFORMATION, GEOGRAPHIC INFORMATION AND MAJOR CUSTOMERS

         SEGMENT INFORMATION

         The Company operates in a single industry segment: the establishment
and management of e-commerce relationships between businesses. The Company
manages its business along geographical lines, thus resulting in three
reportable segments: North America, Europe, and Asia Pacific and Latin America.
The accounting policies of each segment are the same as those described in the
summary of significant accounting policies. Revenues are attributed to a
reportable segment based on the location of the customer. Management evaluates
the performance of each segment on the basis of operating income, excluding
Charges and certain net general and administrative charges. Intersegment
royalties are calculated based upon revenues, as defined, derived from the sales
of certain software products and services at agreed upon percentages between the
segments. The measurement of long-term assets is not a significant factor in
management's evaluation of the results of the reportable segments.

         A summary of the Company's reportable segments as of and for the years
ended December 31, 1999, 1998 and 1997 is presented below (in thousands):

         Revenues attributed to the United States, the Company's country of
domicile, are substantially the same as revenues reported for the reportable
segment of North America (above) for all years presented. Revenues derived from
customers in foreign countries did not exceed 10% in any one country of the
Company's consolidated revenues in 1999, 1998 or 1997.

15.   COMMITMENTS AND CONTINGENCIES

         401(K) PROFIT SHARING PLAN

         During 1998 the Company consolidated its three separate 401(k) savings
and retirement plans into one plan (Plan) for all its domestic employees. In
general, all domestic employees are eligible to participate in the plan after
one month of employment and may contribute up to 15% of their annual salary up
to the maximum allowed by the Internal Revenue Code. Under the consolidated plan
the Company matches employee contributions at 50% to a maximum of 4% of their
annual salary, subject to a $2,200 limit per employee. Prior to consolidating
the plans the Company's matching contributions in 1997 varied from a range of
discretionary to 50% of employees' contributions. Total Company contributions
for its 401(k) plans totaled $776,000, $736,000 and $454,000 for the years ended
December 31, 1999, 1998 and 1997, respectively.

         CREDIT FACILITY

         During 1998 the Company converted its $10.0 million committed line of
credit to an uncommitted credit facility. There are no restrictive covenants or
commitment fees associated with the uncommitted facility. No amounts were
outstanding at December 31, 1999 and 1998.

         LEASES

         The Company leases office facilities, automobiles, fixtures and
equipment under operating leases which extend through 2005. Rent expense under
all operating leases was approximately $5.9 million, $5.5 million and $4.3
million for the years ended December 31, 1999, 1998 and 1997, respectively. At
December 31, 1999 the Company is obligated under these agreements to make the

         CONTINGENCIES

         The Company is involved in claims and other legal actions arising out
of the ordinary course of business, including discontinued operations and the
phase-out of certain non-strategic software products. Additionally, a
shareholder class action lawsuit was filed against the Company in September 1999
(see part I, Item 3 of the Company's December 31, 1999 Form 10-K). While the
ultimate results and outcomes cannot be determined, management does not expect
that they will have a material adverse effect on the Company's results of
operations or financial position.

                          INDEPENDENT AUDITORS' REPORT


The Board of Directors
Harbinger Corporation:


We have audited the accompanying consolidated balance sheets of Harbinger
Corporation and subsidiaries as of December 31, 1999 and 1998, and the related
consolidated statements of operations, comprehensive income (loss),
shareholders' equity, and cash flows for each of the years in the three-year
period ended December 31, 1999. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Harbinger
Corporation and subsidiaries as of December 31, 1999 and 1998, and the results
of their operations and their cash flows for each of the years in the three-year
period ended December 31, 1999 in conformity with generally accepted accounting
principles.
