                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1998
                                   (UNAUDITED)

1.       BASIS OF PRESENTATION

         The accompanying unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q. Accordingly, they
do not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements. The financial
information included herein is unaudited; however, the information reflects all
adjustments (consisting solely of normal recurring adjustments) that are, in the
opinion of management, necessary to a fair presentation of the financial
position, results of operations, and cash flows for the interim periods.
Operating results for the three months and nine months ended September 30, 1998
are not necessarily indicative of the results that may be expected for the year
ended December 31, 1998. For further information, refer to the consolidated
financial statements and footnotes thereto included in Harbinger Corporation's
("Harbinger" or the "Company") Form 10-K for the year ended December 31, 1997
and the Company's current reports on Form 8-K dated February 24, 1998 and May
26, 1998.

         All share, per share and shareholders' equity amounts in the unaudited
consolidated financial statements have been retroactively restated to reflect a
three-for-two stock split in the form of a stock dividend paid on May 15, 1998
(see Note 5).

         Management of the Company has made a number of estimates and
assumptions relating to the reporting of assets and liabilities and the
disclosure of contingent assets and liabilities to prepare these consolidated
financial statements in conformity with generally accepted accounting
principles. Such estimates include charges for in-process product development,
write-off of software development costs, restructuring, acquisition related and
other one-time charges; loss on discontinued operations and allowance for
doubtful accounts. Actual results could differ from management estimates.

         REVENUE RECOGNITION

         On January 1, 1998, the Company adopted Statement of Position 97-2,
Software Revenue Recognition, issued by the Accounting Standards Executive
Committee in October 1997, effective for financial statements for fiscal years
beginning after December 15, 1997. The implementation of this statement did not
have a material impact on the Company's unaudited consolidated financial
statements for the three-month and nine-month periods ended September 30, 1998.

         COMPREHENSIVE INCOME

         On January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130, Reporting Comprehensive Income, issued by the
Financial Accounting Standards Board ("FASB") in June 1997, effective for fiscal
years beginning after December 15, 1997. Comprehensive income includes all
changes in equity during a period except those resulting in investments by
owners and distributions to owners.

         OTHER

          The Company continues to evaluate the requirements of Statement of
Financial Accounting Standards No. 131, Disclosures about Segments of an
Enterprise and Related Information, issued by the FASB in June 1997, effective
for fiscal years beginning after December 15, 1997. The provisions of this
standard do not apply to interim periods in the year of adoption. The Accounting
Standards Executive Committee has issued Statement of Position 98-1, Accounting
for the Costs of Computer Software Developed or Obtained for Internal Use,
effective for fiscal years beginning after December 15, 1998. The Company
adopted this standard on January 1, 1998. The implementation of this statement
did not have a material impact on the Company's unaudited consolidated financial
statements for the three-month and nine-month periods ended September 30, 1998.

2.       ACQUISITION

         Effective March 31, 1998, the Company acquired EDI Works! LLC ("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 with a per-share value of $23.14. The EDI Works! business
combination is not material, and therefore has been accounted for as an
immaterial pooling, with EDI Works! retained earnings of $130,000 at December
31, 1997 being credited directly to the Company's accumulated deficit effective
January 1, 1998. The results of operations of EDI Works! are included in the
Company's consolidated statement of operations for the nine months ended
September 30, 1998. In connection with the EDI Works! acquisition, the Company
incurred a charge of $805,000 for acquisition-related expenses, asset write
downs and integration costs in the consolidated statement of operations for the
nine months ended September 30, 1998.

         Effective July 9, 1998, the Company acquired substantially all of the
assets of the Materials Management Division of MACTEC, Inc., located in Tulsa,
Oklahoma, for approximately $3.5 million in cash, subject to certain
post-closing adjustments. The Company recorded the acquisition using the
purchase method of accounting, with approximately $3.5 million recorded to
goodwill to be amortized ratably over 10 years.


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

         In connection with the acquisitions made in 1998 and 1997 and a
restructuring of the Company effective September 30, 1998, the Company incurred
charges for purchased in-process product development, write-off of software
development costs, restructuring, acquisition related and other one-time charges
("one-time charges"). A summary of the components is as follows (in thousands):

potentially resulting in an increase in such expense categories as a percentage
of total revenues.

4.       DISCONTINUED OPERATIONS

         In the third quarter of 1998 the Board of Directors approved the
discontinuance of the Company's TrustedLink Procurement ("TLP") business
effective September 30, 1998. The Company is reviewing its alternatives and
expects to divest this business within 12 months. The results of operations for
the TLP business for all periods are reported in the accompanying statements of
operations under "Discontinued operations". For the three-month and nine-month
periods ended September 30, 1997, "Discontinued operations" also include
operating results of the TrustedLink Banker division ("Banker"), which was
discontinued in the fourth quarter of 1997. Banker's income for the three-month
and nine-month periods ended September 30, 1997 was $137,000 and $173,000,
respectively.

         Revenues for the TLP business for the nine-month periods ended
September 30, 1998 and 1997 were $2.7 million and $1.1 million, respectively,
and for the three-month periods ended September 30, 1998 and 1997 were $596,000
and $1.1 million, respectively. Revenues for Banker for the nine-month and
three-month periods ended September 30, 1997 were $3.0 million and $1.1 million,
respectively.

         In the third quarter of 1998 the Company provided for an estimated
anticipated loss of $6.4 million related to the disposal of the TLP business. No
income tax expense or benefit was recognized in 1998 or 1997 due to the
Company's net operating loss carryforwards. The remaining assets and liabilities
of the TLP business, excluding cash and certain liabilities, are included in the
Company's consolidated balance sheet at September 30, 1998 and are summarized as
follows (in thousands):

5.       SHAREHOLDERS' EQUITY

         On March 31, 1998, the Company issued 194,497 shares of the Company's
common stock as consideration related to the Company's acquisition of EDI Works!
(See Note 2).

         On May 15, 1998, the Company paid a stock split in the form of a stock
dividend on the Company's common stock to shareholders of record on May 1, 1998
as a result of a three-for-two stock split declared by the Board of Directors on
April 24, 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.


6.       COMMITMENTS

         During 1998 the Company entered into lease agreements for office space
committing the Company to approximately $29 million in total payments through
mid-year 2008, with an average annual commitment of $3.3 million over the next
five years.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
         RESULTS OF OPERATIONS

         The following discussion and analysis should be read in conjunction
with the accompanying consolidated financial statements and notes, the Company's
Form 10-K for the year ended December 31, 1997 and the Company's current reports
on Form 8-K dated February 24, 1998 and May 26, 1998 and the Company's Safe
Harbor Compliance Statement filed herewith as Exhibit 99.1.

OVERVIEW

         Harbinger Corporation (the "Company") generates revenues from various
sources, including revenues for services and license fees for software. Revenues
for services principally include subscription fees for transactions on the
Company's Value Added Network ("VAN") and Internet Value Added Server ("IVAS"),
software maintenance and implementation charges and professional service fees
for consulting and training services. Subscription fees are based on a
combination of monthly access charges and transaction-based usage charges and
are recognized based on actual charges incurred each month. Software maintenance
and implementation revenues represent recurring charges to customers and are
deferred and recognized ratably over the service period. Revenues for
professional services are based on actual services rendered and are recognized
as services are performed. License fees for software are generally recognized
upon shipment, net of estimated returns. Software revenues also include royalty
revenues 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. In 1998 the
Company adopted Statement of Position 97-2, Software Revenue Recognition, issued
by the Accounting Standards Executive Committee. The implementation of this
statement did not have a material impact on the Company's consolidated financial
statements for the period ended September 30, 1998.

         During the nine months ended September 30, 1998, the Company incurred
acquisition and integration related and other one-time charges of $15.9 million
related to acquisitions made since September 30, 1997. These costs related to
business combinations include activities such as cross training, planning,
product integration and marketing ("Integration Activities"). Due to Integration
Activities in the nine months ended September 30, 1998 and 1997, certain
internal expense allocations ("Integration Activity Costs") included in the
"Charge for purchased in-process product development, write-off of software
development costs, restructuring, acquisition related and other one-time
charges" on the consolidated statement of operations may recur in other expense
categories in the future and may result in an increase in some expense
categories as a percentage of total revenues.

         During the third quarter of 1998 the Company implemented a
restructuring plan that included the termination of approximately 10% of its
personnel, the announcement of the discontinuance of certain non-strategic
software products and realigning its internal organizational structure,
including certain senior management. In connection with this plan the Company
recorded a one-time restructuring charge of $11.1 million. The costs related to
restructuring include estimates for asset write downs, termination benefits to
former employees and lease termination costs.

         Total restructuring, acquisition and integration and other one-time
charges ("one-time charges") for the nine months ended September 30, 1998 and
1997 were $27.0 million and $20.1 million, respectively. One-time charges
include management estimates. Actual costs could differ from such estimates.

         During the third quarter of 1998, the Company also announced its
intention to divest its TrustedLink Procurement business (see Note 4 to the
accompanying unaudited consolidated financial statements) during the next 12
months. The results of operations for this business have been reclassified to
discontinued operations for all periods in the accompanying unaudited
consolidated financial statements.
   12
1998 ACQUISITIONS

         Effective March 31, 1998, the Company acquired EDI Works! LLC ("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. The results of
operations of EDI Works! are included in the Company's consolidated statement of
operations for the nine months ended September 30, 1998.

         In connection with the EDI Works! acquisition, the Company incurred a
charge of $47,000 for acquisition related expenses, asset write downs and
integration costs in the consolidated statement of operations for the three
months ended September 30, 1998 and $805,000 for the nine months ended September
30, 1998.

         Effective July 9, 1998, the Company acquired substantially all of the
assets of the Materials Management Division of MACTEC, Inc., located in Tulsa,
Oklahoma, for approximately $3.5 million in cash, subject to certain
post-closing adjustments. The Company recorded the acquisition using the
purchase method of accounting, with approximately $3.5 million recorded to
goodwill to be amortized ratably over ten years.


RESULTS OF OPERATIONS

   REVENUES

         Total revenues increased 20% from $81.9 million in the nine months
ended September 30, 1997 to $98.6 million in the same period in 1998. Revenues
for services increased 39% from $46.1 million in the nine months ended September
30, 1997 to $63.9 million in the same period in 1998. This increase is
attributable to growth in transaction fees, increased professional services,
increased maintenance revenues and revenues from companies acquired since
September 1997. Software revenue decreased 3% from $35.8 million in the nine
months ended September 30, 1997 to $34.8 million in the same period in 1998. The
overall decrease in software revenue for the nine months ended September 30,
1998 compared to the same period in 1997 reflects offsetting effects of modest
declines in the Company's PC and UNIX product lines, decreased royalty revenues
and increases in license fees from the NT product line.

         Total revenues increased 21% from $29.2 million in the three months
ended September 30, 1997 to $35.4 million in the same period in 1998. Revenues
for services increased 36% from $16.2 million in the three months ended
September 30, 1997 to $22.1 million in the same period in 1998. This increase is
attributable to growth in transaction fees, increased professional services,
increased maintenance revenues and revenues from companies acquired since
September 1997. Software revenue increased 3% from $12.9 million in the three
months ended September 30, 1997 to $13.3 million in the same period in 1998. The
net increase is a result of decreases in software license fees from the
Company's UNIX product lines and decreases in royalty revenue offset by $1.1
million of software shipped and license fees recognized in the third quarter of
1998 for orders placed in the second quarter of 1998 that the Company did not
ship.

   DIRECT COSTS

         Direct costs for services increased from $15.8 million, or 34.3% of
services revenues, in the nine months ended September 30, 1997, to $24.8
million, or 38.8% of services revenues, in the nine months ended September 30,
1998. The increase in direct costs for services as a percentage of services
revenues is primarily attributable to growth in the Company's professional
services practice, which has lower margins than other components of the
Company's service revenues. The increase in direct costs was partially offset by
the impact of Integration Activity Costs. Direct costs for software decreased
from $5.8 million, or 16.1% of software revenues, in the nine months ended
September 30, 1997, to $3.2 million, or 9.2% of software revenues, in the nine
months ended September 30, 1998. The decrease in direct software costs as a
percentage of software revenues from the first nine months of 1997 compared to
the comparable period of 1998 primarily reflects the effects of a decrease in
software amortization in  
   13
1998 as a result of writing off capitalized and purchased software development
in connection with certain business combinations in 1997.

         Direct costs for services increased from $5.7 million, or 35.2% of
services revenue, in the three months ended September 30, 1997, to $9.3 million,
or 41.8% of services revenue, in the three months ended September 30, 1998. The
increase in direct costs for services as a percentage of services revenues is
primarily attributable to growth in the Company's professional services
practice, which has lower margins than other components of the Company's service
revenues. Direct costs for software decreased from $1.8 million, or 13.6% of
software revenues, in the three months ended September 30, 1997, to $1.3
million, or 9.9% of software revenues, in the three months ended September 30,
1998, primarily as a result of a decrease in software amortization in 1998 as a
result of writing off capitalized and purchased software development in
connection with certain business combinations in 1997.

   SELLING AND MARKETING

         Selling and marketing expenses increased 23% from $18.8 million, or
23.0% of revenues, in the nine months ended September 30, 1997 to $23.2 million,
or 23.6% of revenues, in the nine months ended September 30, 1998. For the third
quarters, selling and marketing expenses increased 43% from $6.4 million, or
21.8% of revenues, in the three months ended September 30, 1997, to $9.1
million, or 25.7% of revenues, in the three months ended September 30, 1998. For
both the nine-month and three-month period comparisons, the increase in expenses
is primarily due to increases in sales and marketing personnel and related
selling costs. For the quarters, selling and marketing expenses as a percentage
of revenues increased from the third quarter of 1997 compared to the third
quarter of 1998 due to increases in sales and marketing personnel and related
selling costs and a decrease in Integration Activity Costs.

   GENERAL AND ADMINISTRATIVE

         General and administrative expenses increased 61% from $15.2 million in
the nine months ended September 30, 1997 to $24.5 million in the nine months
ended September 30, 1998. As a percentage of revenues, these expenses increased
from 18.6% of revenues in the nine months ended September 30, 1997 to 24.8% of
revenues in the nine months ended September 30, 1998. For the third quarters,
general and administrative expenses increased 165% from $5.1 million in the
three months ended September 30, 1997 to $13.6 million in the three months ended
September 30, 1998. As a percentage of revenues, these expenses increased from
17.7% of revenues in the three months ended September 30, 1997 to 38.5% of
revenues in the three months ended September 30, 1998. For both the nine-month
and three-month period comparisons, the increase in general and administrative
expenses is primarily due to a $6.5 million provision in the third quarter of
1998 in the Company's allowance for doubtful accounts. This increase relates
primarily to management's concern regarding the recent financial condition of a
reseller. Management intends to continue to pursue collections of these
accounts, but has reserved based on management's estimate of collectibility, for
these accounts. Actual results could differ from this estimate.

         Adjusting for the impact of the specific charge to the allowance for
doubtful accounts, general and administrative expenses would have increased 18%
to $18.0 million, or 18.2% of revenues, for the nine months ended September 30,
1998 compared to the same period in 1997 and would have increased 39% to $7.1
million, or 20.1% of revenues, for the three months ended September 30, 1998
compared to the third quarter of 1997. The increase in expenses as a percentage
of revenues in the nine months ended September 30, 1998 is significantly
impacted by increases in expenses in the third quarter of 1998. The increase in
the third quarter of 1998 compared to the third quarter of 1997 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 the effect of Integration
Activity Costs between periods.
   14
   DEPRECIATION AND AMORTIZATION

         Depreciation and amortization increased 19% from $4.9 million in the
nine months ended September 30, 1997 to $5.8 million in the nine months ended
September 30, 1998. As a percentage of revenues, these expenses were 6.0% and
5.9% of revenues for the nine-month periods ended September 30, 1997 and 1998,
respectively. For the third quarters, depreciation and amortization increased
21% from $1.7 million in the three months ended September 30, 1997 to $2.0
million in the three months ended September 30, 1998. As a percentage of
revenues, these expenses were 5.8% and 5.7% for the three months ended September
30, 1997 and September 30, 1998, respectively. The increase in depreciation and
amortization for the nine-month and three-month periods of 1998 compared to
1997, respectively, is a result of additions to fixed assets and equipment and
reflects certain investments in infrastructure.

   PRODUCT DEVELOPMENT

         Total expenditures for product development, including capitalized
software development costs, decreased 31% from $15.4 million in the nine months
ended September 30, 1997 to $10.6 million in the same period in 1998. The
Company capitalized product development costs of $3.8 million and $2.8 million
in the nine months ended September 30, 1997 and 1998, respectively, which
represented 24.7% and 26.7% of total expenditures for product development in
these respective periods. As a percentage of total revenues, product development
expenses decreased from $11.6 million, or 14.1% of revenues, in the nine months
ended September 30, 1997, to $7.8 million, or 7.8% of revenues, in the nine
months ended September 30, 1998. The decrease in total expenditures for product
development for the nine months ended September 30, 1998 compared to the same
period in 1997 is primarily attributable to efficiencies gained in consolidating
development resources of acquired companies in the last 12 months, offset by the
impact of Integration Activity Costs. Amortization of capitalized software
development costs is charged to direct costs of software revenues and totaled
$2.7 million and $1.1 million, in the nine months ended September 30, 1997 and
1998, respectively.

         Total expenditures for product development, including capitalized
software development costs, decreased 28% from $5.1 million in the three months
ended September 30, 1997 to $3.6 million in the same period in 1998. The Company
capitalized software development costs of $1.3 million and $794,000 in the three
months ended September 30, 1997 and 1998, respectively, which represented 26.0%
and 21.8% of total expenditures for product development in these respective
periods. Product development expenses decreased from $3.8 million, or 12.8% of
revenues, in the three months ended September 30, 1997, to $2.8 million, or 8.0%
of revenues, in the three months ended September 30, 1998. The decrease in total
expenditures for product development for the third quarter of 1998 compared to
the third quarter of 1997 is primarily attributable to efficiencies gained in
consolidating development resources of acquired companies in the last 12 months,
offset by the impact of Integration Activity Costs. The decrease in the
percentage of capitalized product development costs as a component of total
expenditures for product development in the third quarter of 1998 compared to
the third quarter of 1997 is primarily attributable to a decrease in development
activities associated with products that have reached technological feasibility.
Amortization of capitalized software development costs is charged to direct cost
of software revenues and totaled $922,000 and $422,000 in the three months ended
September 30, 1997 and 1998, respectively.

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

         Total one-time charges increased 35% from $20.1 million for the nine
months ended September 30, 1997 to $27.0 million for the comparable period in
1998. Certain charges in 1998 were incurred as a result of continued efforts to
integrate the following recent acquisitions: $13.7 million attributable to
Premenos Technology Corp. ("Premenos") acquired on December 19, 1997; $1.4
million attributable to Atlas Products International, Limited ("Atlas") acquired
on October 23, 1997; and $805,000 attributable to EDI Works! acquired on March
31, 1998. Additionally, the Company recorded $11.1 million in termination
benefits to former employees, lease termination costs, asset write downs and
other charges attributable to a restructuring effective September 30, 1998. For
the nine months ended September 30, 1997 the one-time charges of $20.1 million
were attributable to the following acquisitions:
   15
$11.9 million to Supply Tech, Inc.; $4.3 million to Harbinger NET Services LLC;
and $3.9 million to Acquion, Inc. ("Acquion). (See Note 3 to the accompanying
unaudited consolidated financial statements.)

         Total one-time charges for the quarter ended September 30, 1997 were
$3.9 million compared to $14.0 million in the quarter ended September 30, 1998.
The charges for the three months ended September 30, 1998 were attributable as
follows: $2.7 million to Premenos; $200,000 to Atlas; $47,000 to EDI Works!; and
$11.1 million in termination benefits to former employees, lease termination
costs, asset write downs and other charges in connection with to a restructuring
effective September 30, 1998. The three-month charges for the comparable period
in 1997 were all attributable to the acquisition of Acquion.

         Certain one-time charges were made based on management estimates.
Actual results could differ from such estimates.

INTEREST INCOME, NET

         Interest income, net, increased 44% from $2.6 million for the nine
months ended September 30, 1997 to $3.8 million for the nine months ended
September 30, 1998. On a quarter-to-quarter comparison, interest income, net,
was $1.2 million in the third quarters of 1997 and 1998. The increase for the
nine months ended September 30, 1998 compared to the comparable period ended
September 30, 1997 is a result of higher average balances of cash and cash
equivalents and short-term investments in 1998 compared to 1997.

INCOME TAXES

         Income tax expense decreased 61% from $1.8 million for the nine months
ended September 30, 1997 to $705,000 for the nine months ended September 30,
1998. For the quarters ended September 30, 1997 and 1998 income tax expense
increased from $446,000 to $560,000, respectively. All changes in income tax
expense are attributable to the nondeductibility of certain expenses for tax
purposes incurred in 1997, particularly acquisition and integration related
charges, and current tax liabilities incurred in certain foreign and state
jurisdictions.

DISCONTINUED OPERATIONS

         On September 30, 1998, the Company discontinued its TrustedLink
Procurement ("TLP") business, which had been generating lower than desired
profitability and growth. The Company plans to divest the discontinued business
during the next twelve months. The results of operations for this business have
been reclassified to discontinued operations for all periods in the accompanying
unaudited consolidated financial statements. Reclassified losses for the TLP
business were $1.8 million and $10.7 million for the nine-month periods ended
September 30, 1998 and 1997, respectively, and were $938,000 and $10.7 million
for the three-month periods ended September 30, 1998 and 1997, respectively. In
the third quarter of 1998 the Company also provided for an estimated anticipated
loss on the disposal of the TLP business of $6.4 million. Actual costs could
differ from this estimate.

         In the fourth quarter of 1997 the Company discontinued its TrustedLink
Banker division ("Banker") and the unaudited consolidated financial statements
also reflect the impact of reclassifying the Banker results of operations to
discontinued operations. Such reclassified income for the three-month and
nine-month periods ended September 30, 1997 were $137,000 and $173,000,
respectively.

NET LOSS AND EARNINGS (LOSS) PER SHARE

         Net loss applicable to common shareholders increased from $22.6
million, or $0.61 per share, for the nine months ended September 30, 1997 to
$22.8 million, or $0.55 per share, for the nine months ended September 30, 1998.
Net income, adjusted to exclude one-time charges, a specific $6.5 million charge
to general and administrative expenses in the third quarter of 1998, a net loss
from discontinued operations and an extraordinary loss on debt extinguishment in
1997, net of the effect of income taxes, would have been $7.7 million, or $0.19
per share, for the nine months ended September 30, 1997, compared to $12.1
million, or $0.28 per share, for the nine
   16
months ended September 30, 1998, representing a 57% increase from 1997 to 1998.
Net income, excluding all aforementioned charges except the specific $6.5
million charge to general and administrative expenses in the third quarter of
1998, would have been $7.7 million, or $0.19 per share, for the nine months
ended September 30, 1997, compared to $8.2 million, or $0.19 per share, for the
nine months ended September 30, 1998, representing a 6% increase from 1997 to
1998.

         Net loss applicable to common shareholders increased from $9.0 million,
or $0.23 per share, for the quarter ended September 30, 1997 to $23.4 million,
or $0.56 per share, for the quarter ended September 30, 1998. Net income,
adjusted to exclude one-time charges, a specific $6.5 million charge to general
and administrative expenses in the third quarter of 1998 and a net loss from
discontinued operations, net of the effect of income taxes, would have been $3.7
million, or $0.09 per share, for the quarter ended September 30, 1997, compared
to $3.0 million, or $0.07 per share, for the quarter ended September 30, 1998,
representing a 20% decrease from 1997 to 1998. Net income (loss), excluding all
aforementioned charges except the specific $6.5 million charge to general and
administrative expenses in the third quarter of 1998, would have been income of
$3.7 million, or $0.09 per share, for the three months ended September 30, 1997,
compared to a loss of $961,000, or $0.02 per share, for the three months ended
September 30, 1998, representing a 126% decrease from 1997 to 1998.

         Earnings (loss) per share in future periods, for both basic and fully
diluted presentations, could be impacted by a potential change in the number of
shares of common stock outstanding as a result of the effects of the Company's
common stock repurchase program and the Company's repricing of certain
unexercised employee stock options held by employees other than certain senior
executive officers. Both programs were authorized by the Company's Board of
Directors in October 1998.

LIQUIDITY AND CAPITAL RESOURCES

         The Company's working capital decreased $14.6 million from $94.3
million as of December 31, 1997 to $79.7 million as of September 30, 1998. Net
cash provided by operating activities decreased 40% from $4.8 million for the
nine months ended September 30, 1997 to $2.9 million for the comparable period
in 1998, primarily as a result of liquidation of liabilities incurred due to
one-time charges associated with acquisitions since September 30, 1997.

         Net cash used in investing activities increased $2.7 million from $28.9
million for the nine months ended September 30, 1997 to $31.6 million for the
nine months ended September 30, 1998 due to an increase in short-term
investments over cash and cash equivalents between the periods offset by a
decrease in cash outlays for acquisitions of companies. Additionally, the
Company continues to acquire fixed assets and equipment in 1998.

         Net cash provided by financing activities decreased $47.1 million from
$58.0 million for the nine months ended September 30, 1997 to $10.9 million for
the nine months ended September 30, 1998 primarily resulting from the Company
receiving $60.0 million from a secondary stock offering in July 1997.

         Management expects that the Company will continue to be able to fund
its operations, investment needs and capital expenditures through cash flows
generated from operations, cash on hand, borrowings under the Company's $10
million credit facility and additional equity and debt capital. Management
believes that outside sources for debt and additional equity capital, if needed,
will be available to finance expansion projects and any potential future
acquisitions. The form of any financing will vary depending upon prevailing
market and other conditions and may include short or long term borrowings from
financial institutions, or the issuance of additional equity or debt securities.
However, there can be no assurances that funds will be available on terms
acceptable to the Company. Several factors could have an impact on the Company's
cash flows in the upcoming quarters, including the effects of the Company's
recent implementation of a common stock repurchase program (see Note 7 to the
accompanying unaudited consolidated financial statements), liquidation of
liabilities incurred due to a restructuring of the Company and a discontinued
operation effective September 30, 1998, and anticipated outlays for the
Company's on-going 1998 effort to enhance and consolidate its IT infrastructure.
The Company does not believe that inflation has had a material impact on its
business. However, there can be no assurance that Harbinger's business will not
be affected by inflation in the future.

YEAR 2000 READINESS

         Many currently installed computer systems and software products will
not properly process date information in the time period leading up to,
including and following the year 2000. These systems and products often store
and process the year field of date information as two digit numbers, and
misinterpret dates in the year 2000 and beyond as being dates in the year 1900
or subsequent years. This "Year 2000" issue impacts Harbinger both with respect
to its customers as a developer and vendor of computer software products and
services and internally for its information technology ("IT") and non-IT
systems.

         The Company formed a Year 2000 Steering Committee in July 1998 to
formally address the Company's Year 2000 issues, which formalized the Company's
Year 2000 assessment program begun in March 1997. The Year 2000 Steering
Committee has overseen the Company's Year 2000 Readiness Assessment Program,
which includes establishing the Company's standard for Year 2000 Readiness,
designing test parameters for its products, IT and non-IT systems, overseeing
the Company's remediation program, including establishing priorities for
remediation and allocating available resources, overseeing the communication of
the status of the Company's efforts to its customers, and establishing
contingency plans in the event the Company experiences Year 2000 disruptions.

         The Company describes its products and services as "Year 2000 Ready"
when they have been successfully tested using the procedure proscribed in its
Readiness Assessment Program. This procedure defines the criteria used to design
tests that seek to determine the Year 2000 readiness of a product. Under the
Company's criteria, a software product is Year 2000 Ready if it:

     1.  Correctly handles date information before, during, and after January 1,
         2000, accepting date input, providing date output and performing
         calculation on dates or portions of dates.

     2.  Functions accurately and without interruption before, during and after
         January 1, 2000 without changes in operation associated with the advent
         of the new century assuming correct configuration.

     3.  Where appropriate, responds to two-digit date input in a way that
         resolves the ambiguity as to century in a disclosed, defined and
         pre-determined manner.

     4.  Stores and provides output of date information in ways that are
         unambiguous as to century.

     5.  Manages the leap year occurring in the year 2000, following the
         quad-centennial rule.

         As of September 30, 1998 Company management estimates that
approximately 90% of its product readiness testing has been completed. While
many of the Company's products are presently Year 2000 Ready, the Company
currently estimates that all of its continuing products will be available to
customers in a Year 2000 Ready version by the end of 1998. Certain of the
Company's customers are currently using legacy versions of the Company's
products for which a Year 2000 Ready version will not be developed. The Company
has developed migration plans to move such customers to functionally similar
Year 2000 Ready products. The Company is also in the process of implementing a
website on the Internet that will include a general overview of the Company's
Readiness Assessment Program, including a list of products and the applicable
Year 2000 Ready version numbers of such products.

         The Company is presently engaged in a significant upgrade of
substantially all of its core IT systems, including those related to sales,
customer service, human resources, finance, accounting and other enterprise
resource planning functions, as a result of its growth in recent years. The
Company believes that the upgraded systems, which it expects to have
substantially implemented by mid-year 1999, are all Year 2000 Ready. The Company
is reviewing its remaining IT systems for Year 2000 Readiness, and expects to
modify, replace or discontinue the use of non-compliant systems before the end
of 1999. In addition, the Company is in the process of evaluating its Year 2000
readiness with respect to non-IT systems, including systems embedded in the
Company's communications and office facilities. In many cases these facilities
have been recently upgraded or are scheduled
   18
to be upgraded before year-end 1999 as a result of the Company's growth in
recent years. The Company is in the process of distributing surveys to its
principal IT and non-IT systems and services vendors soliciting information on
their Year 2000 Readiness as part of this review. The Company is also surveying
its vendors' websites for additional related information.

         The majority of the work performed for the Company's Year 2000
Readiness Assessment Program has been completed by the Company's staff.
Additionally, the Company engaged outside advisors to evaluate the Readiness
Assessment Program and to participate in certain elements of product testing.
The total costs for completing the Year 2000 Readiness Assessment Program,
including modifications to the Company's software products, is estimated to be
between $1 million and $2 million, funded through the Company's internal
operating cash flows. This cost does not include the cost for new software, or
for modifications to existing software, for the Company's core IT and non-IT
systems, as these projects were not accelerated due to the Year 2000 issue.
Approximately $200,000 to $300,000 in cost remains to be incurred to complete
the Company's Readiness Assessment Program.

         The Company believes that the purchasing patterns of customers and
potential customers may be affected by Year 2000 issues in a variety of ways.
Many companies are expending significant resources to correct or patch their
current software systems for Year 2000 compliance. These expenditures may result
in reduced funds available to purchase software products such as those offered
by the Company. Potential customers may also choose to defer purchasing Year
2000 compliant products until they believe it is absolutely necessary, thus
resulting in potentially stalled market sales within the industry. Conversely,
Year 2000 issues may cause other companies to accelerate purchases, thereby
causing an increase in short-term demand and a consequent decrease in long-term
demand for software products. In addition, Year 2000 issues could cause a
significant number of companies, including current Company customers, to
reevaluate their current software needs, and as a result switch to other systems
or suppliers. Any of the foregoing could result in a material adverse effect on
the Company's business, operating results and financial condition.

         At present the Company has only preliminarily discussed contingency
plans in the event that Year 2000 non-compliance issues materialize. The Company
expects to formalize its contingency plans prior to year-end 1999. In the case
of certain of the Company's value-added network operations, it will be difficult
for the Company to seamlessly implement alternative service arrangements due to
the nature and complexity of the customer interface. While the Company believes
that its Readiness Assessment Program is addressing the risks specific to the
Company for the Year 2000 issue, including its operations in markets outside of
the United States, it cannot be assured that events will not occur that could
have a material adverse impact on its business, operating results and financial
condition. Such events include the risk of lawsuits from customers and the
inability to process data internally on its IT systems. Further, the Company is
aware of the risk that domestic and international third parties, including
vendors and customers of the Company, will not adequately address the Year 2000
problem and the resultant potential adverse impact on the Company. Regardless of
whether the Company's products are Year 2000 compliant, there can be no
assurance that customers will not assert Year 2000 related claims against the
Company.

EURO CONVERSION

         Effective January 1, 1998, eleven of the 15 member countries of the
European Union are scheduled to adopt 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 will be affected by the conversion to the
euro. The Company is currently evaluating its products and systems. The failure
to adequately address the euro conversion issues could effect the Company's
ability to offer software and services in the effected countries, as well as its
ability to operate internal systems. While the company believes that it can
successfully remediate all related issues, there can be no assurance that it
will do so in a timely manner. The failure to do so could have an adverse effect
on the Company.

RECENT ACCOUNTING PRONOUNCEMENTS

          In 1998 the Company adopted Statement of Position 97-2, Software
Revenue Recognition, issued by the Accounting Standards Executive Committee, and
Statement of Financial Accounting Standards No. 130, Reporting Comprehensive
Income, issued by the Financial Accounting Standards Board. The Company adopted
Statement of Position 98-1, Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use, issued by the Accounting Standards
Executive Committee effective for fiscal years beginning after December 15,
1998, on January 1, 1998. The implementation of these statements did not have a
material impact on the Company's accompanying unaudited consolidated financial
statements for the three-month and nine-month periods ended September 30, 1998.

         The Company continues to evaluate the requirements of Statement of
Financial Accounting Standard No. 131, Disclosures about Segments of an
Enterprise and Related Information, which is effective for the year ending
December 31, 1998 but does not apply to interim periods in the year of adoption.
