                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  JUNE 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 six months ended June 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 4).

         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 six-month periods ended June 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
currently anticipates early adoption of this standard, possibly beginning in the
third quarter of 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 six months ended June 30,
1998.

         In connection with the EDI Works! acquisition, the Company incurred a
charge of $758,000 for acquisition-related expenses, asset write downs and
integration costs in the consolidated statement of operations for the six months
ended June 30, 1998.


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, the Company
incurred charges for purchased in-process product development, write-off of
software development costs, restructuring, acquisition related and other
one-time charges ("acquisition and integration related charges"). A summary of
the components is as follows (in thousands):

         Approximately $1.7 million of the costs and expenses incurred in the
three months ended June 30, 1998 and $3.7 million for the six months ended June
30, 1998 in connection with recent acquisitions included certain internal
expense allocations which may recur in other expense categories in the future,
potentially resulting in an increase in such expense categories as a percentage
of total revenues.


4.       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 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
payable 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 retroactively restated to reflect
the split for all periods presented.

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 consolidated financial statements and notes thereto included elsewhere
herein and 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.

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"), software maintenance and implementation
charges and charges 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
consulting and training 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 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 June 30, 1998.

         During the first half of 1998, the Company continued to work through
integration issues associated with its three acquisitions made between October
1997 and March 1998. In the three months ended June 30, 1998 the Company
incurred $5.0 million in acquisition and integration related and other one-time
charges associated with these recent acquisitions. 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 six months ended June 30, 1998, certain internal expense
allocations ("Integration Activity Costs") included in the acquisition and
integration related charges 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. The total acquisition and integration related charges for the
six months ended June 30, 1998 and 1997 was $13.0 million and $16.2 million,
respectively. The Company expects to incur additional merger related charges
from the completed acquisitions totaling $2.9 million in subsequent quarters
of 1998.


1998 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. 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 six months ended June 30, 1998.

         In connection with the EDI Works! acquisition, the Company incurred a
charge of $323,000 for acquisition related expenses, asset write downs and
integration costs in the consolidated statement of operations for the three
months ended March 31, 1998 and $435,000 for the three months ended June 30,
1998.

RESULTS OF OPERATIONS

   REVENUES

         Total revenues increased 24% from $52.7 million in the six months ended
June 30, 1997 to $65.4 million in the same period in 1998. Revenues for services
increased 45% from $29.8 million in the six months ended June 30, 1997 to $43.3
million in the same period in 1998. This increase is attributable to growth in
VAN fees, increased professional services, increased maintenance and
installation revenues as well as three acquisitions made in the last 12 months,
of which two were treated as immaterial poolings for accounting purposes and one
was a purchase. Revenue from software sales decreased 4% from $22.9 million in
the six months ended June 30, 1997 to $22.1 million in the same period in 1998.
The overall decrease in software sales for the six months ended June 30, 1998
compared to the same period in 1997 was heavily impacted by a decline in
software sales in the second quarter 1998. Several factors contributed to the
decline, including the Company's inability to ship $1.1 million in software
orders placed in the second quarter. The decline for the six months of 1998 was
partially offset by a first quarter 1998 increase in software sales of 9%
compared to the first quarter of 1997.

         Total revenues increased 21% from $28.4 million in the three months
ended June 30, 1997 to $34.3 million in the same period in 1998. Revenues for
services increased 50% from $15.1 million in the three months ended June 30,
1997 to $22.6 million in the same period in 1998. This increase is attributable
to growth in VAN fees, increased professional services, increased maintenance
and installation revenues as well as three acquisitions made in the last 12
months, of which two were treated as immaterial poolings for accounting purposes
and one was a purchase. Revenues from software license fees decreased 13% from
$13.3 million in the three months ended June 30, 1997 to $11.6 million in the
same period in 1998 primarily as a result of missed shipments, as discussed
above, plus a modest decline in sales of the Company's PC product lines.

   DIRECT COSTS

         Direct costs for services increased from $10 million, or 33.6% of
services revenues, in the six months ended June 30, 1997, to $16.7 million, or
38.5% of services revenues, in the six months ended June 30, 1998. The increase
in direct costs for services as a percentage of services revenues reflects a
modest decrease in professional service margins as a result of nonbillable work
performed by the professional services staff for both internal and external
projects and the use of higher cost outside contractors. The Company expects the
use of outside contractors to decrease by the end of 1998. This increase in
direct costs was partially offset by the impact of Integration Activity Costs.
Direct costs for software decreased from $4.0 million, or 17.5% of software
revenues, in the six months ended June 30, 1997, to $2.0 million, or 8.9% of
software revenues, in the six months ended June 30, 1998. The decrease in direct
software costs as a percentage of software revenues from the first six months of
1997 compared to the comparable period of 1998 primarily reflects the effects of
a decrease in software amortization in 1998 as a result of write-offs of
capitalized software development in connection with certain business
combinations in 1997 and a decrease in royalty fees paid by the Company for the
use of third parties' products embedded in the Company's products.

         Direct costs for services increased from $5.2 million, or 34.5% of
services revenue, in the three months ended June 30, 1997, to $9.0 million, or
39.9% of services revenue, in the three months ended June 30, 1998. The increase
in direct costs for services as a percentage of services revenues reflects a
modest decrease in professional service margins as a result of nonbillable work
performed by the professional services staff for both internal and external
projects and the use of higher cost outside contractors. This increase in direct
costs was partially offset by the impact of Integration Activity Costs. Direct
costs for software decreased from $2.2 million, or 16.2% of software revenues,
in the three months ended June 30, 1997, to $1.0 million, or 8.6% of software
revenues, in the three months ended June 30, 1998, primarily as a result of a
decrease in software amortization in 1998 as a result of write-offs of
capitalized software development in connection with certain business
combinations in 1997 and a decrease in royalty fees paid by the Company for the
use of third parties' products embedded in the Company's products.

<PAGE>   12

   SELLING AND MARKETING

         Selling and marketing expenses increased 16% from $12.5 million, or
23.7% of revenues, in the six months ended June 30, 1997 to $14.5 million, or
22.2% of revenues, in the six months ended June 30, 1998. For the second
quarters, selling and marketing expenses increased 17% from $6.7 million, or
23.4% of revenues, in the three months ended June 30, 1997 to $7.8 million, or
22.7% of revenues, in the three months ended June 30, 1998. For both the
six-month and three-month period comparisons, the increase in expenses is
primarily due to increased sales and marketing personnel. The decrease in
selling and marketing expenses as a percentage of revenues is primarily due to
the effect of increased revenues, efficiencies gained through recent mergers and
the effect of Integration Activity Costs.



   GENERAL AND ADMINISTRATIVE

         General and administrative expenses increased 14% from $10.1 million in
the six months ended June 30, 1997 to $11.5 million in the six months ended June
30, 1998. As a percentage of revenues, these expenses decreased from 19.1% of
revenues in the six months ended June 30, 1997 to 17.6% of revenues in the six
months ended June 30, 1998. For the second quarters, general and administrative
expenses increased 15% from $5.3 million in the three months ended June 30, 1997
to $6.0 million in the three months ended June 30, 1998. As a percentage of
revenues, these expenses decreased from 18.5% of revenues in the three months
ended June 30, 1997 to 17.6% of revenues in the three months ended June 30,
1998. For both the six-month and three-month period comparisons, the decrease in
general and administrative expenses as a percentage of revenues reflects
efficiencies gained in consolidation of merged companies over the past year and
the effect of Integration Activity Costs.


   DEPRECIATION AND AMORTIZATION

         Depreciation and amortization increased 28% from $3.2 million in the
six months ended June 30, 1997 to $4.1 million in the six months ended June 30,
1998. As a percentage of revenues, these expenses increased from 6.1% of
revenues in the six months ended June 30, 1997 to 6.3% of revenues in the six
months ended June 30, 1998. For the second quarters, depreciation and
amortization increased 29% from $1.6 million in the three months ended June 30,
1997 to $2.1 million in the three months ended June 30, 1998. As a percentage of
revenues, these expenses were 5.7% and 6.1% for the three months ended June 30,
1997 and June 30, 1998, respectively. The increase in depreciation and
amortization for the six-month and three-month periods of 1998 compared to 1997,
respectively, is a result of additions to property, plant and equipment,
primarily in computer hardware and software.


   PRODUCT DEVELOPMENT

         Total expenditures for product development, including capitalized
software development costs, decreased from $10.3 million in the six months ended
June 30, 1997 to $7.3 million in the same period in 1998. The Company
capitalized product development costs of $2.5 million and $2.0 million in the
six months ended June 30, 1997 and 1998, respectively, which represented 24.1%
and 27.7% of total expenditures for product development in these respective
periods. As a percentage of total revenues, product development expenses
decreased from $7.8 million, or 14.8% of revenues, in the six months ended June
30, 1997, to $5.3 million, or 8.2% of revenues, in the six months ended June 30,
1998, reflecting efficiencies from rationalizing product lines for the merged
companies and the effect of Integration Activity Costs. Amortization of
capitalized software development costs is charged to direct costs of software
revenues and totaled $1.8 million and $575,000, in the six months ended June 30,
1997 and 1998, respectively.

<PAGE>   13
         Total expenditures for product development, including capitalized 
software development costs, decreased from $5.0 million in the three months
ended June 30, 1997 to $3.7 million in the same period in 1998. The Company
capitalized software development costs of $1.3 million and $1.1 million in the
three months ended June 30, 1997 and 1998, respectively, which represented 26.1%
and 29.9% of total expenditures for product development in these respective
periods. As a percentage of total revenues, product development expenses were
$3.7 million, or 13.2% of revenues, in the three months ended June 30, 1997, and
$2.6 million, or 7.7% of revenues in the three months ended June 30, 1998,
reflecting efficiencies from rationalizing product lines for the merged
companies and the effect of Integration Activity Costs. Amortization of
capitalized software development costs is charged to direct cost of software
revenues and totaled $899,000 and $307,000 in the three months ended June 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

         Charges for purchased in-process product development, write-off of
software development costs, restructuring, acquisition related and other
one-time charges ("acquisition and integration related charges") decreased 20%
from $16.2 million for the six months ended June 30, 1997 to $13.0 million for
the comparable period in 1998. The charges in 1998 were incurred as a result of
continued efforts to integrate recent acquisitions: 1) $11 million attributable
to Premenos Technology Corp. ("Premenos") acquired on December 19, 1997, 2) $1.2
million to Atlas Products International, Limited ("Atlas") acquired on October
23, 1997, and 3) $758,000 to EDI Works!. The Company expects to incur additional
acquisition and integration related charges of $2.9 million in subsequent
periods in 1998. For the six months ended June 30, 1997 the acquisition and
integration related charges of $16.2 million were attributable to: 1) $11.9
million for Supply Tech, Inc., and 2) $4.3 million to Harbinger NET Services.
(See Note 3 to the unaudited consolidated financial statements.)

         There were no acquisition and integration related charges in the
quarter ended June 30, 1997 compared to $5 million in the quarter ended June 30,
1998. The three-month 1998 charges were attributable to: 1) $ 3.9 million to
Premenos, 2) $677,000 to Atlas, and 3) $435,000 to EDI Works!

INTEREST INCOME, NET

         Interest income, net, increased 81% from $1.4 million for the six
months ended June 30, 1997 to $2.6 million for the six months ended June 30,
1998. On a quarter-to-quarter comparison, interest income, net, increased 82%
from $695,000 in the second quarter of 1997 to $1.3 million in the second
quarter of 1998. The increase in all periods is due to an increase in combined
cash and cash equivalents and short-term investments from $60.0 million at June
30, 1997 to $105.1 million at June 30, 1998, primarily as a result of a
secondary stock offering in July 1997, exercises of stock options and warrants
and issuance of stock under the employee stock purchase plan in the last 12
months.

INCOME TAXES

         Income tax expense decreased 89% from $1.4 million for the six months
ended June 30, 1997 to $145,000 for the six months ended June 30, 1998. For the
quarters ended June 30, 1997 and 1998 income tax expense decreased from $1.7
million to $9,000, respectively. All decreases in income tax expense are
attributable to the nondeductibility of certain expenses for tax purposes
incurred in 1997, particularly acquisition and integration related charges.

NET INCOME (LOSS) AND EARNINGS (LOSS) PER SHARE

         Net income (loss) applicable to common shareholders increased from a
loss of $13.6 million, or $0.37 per share, for the six months ended June 30,
1997 to net income of $622,000, or $0.01 per share, for the six months ended
June 30, 1998. Net income, adjusted to exclude acquisition and integration
related charges, and an extraordinary loss on debt extinguishment in 1997, net
of the effect of income taxes, would have been $4.0 million,

<PAGE>   14

or $0.10 per share, for the six months ended June 30, 1997, compared to $8.6
million, or $0.19 per share, for the six months ended June 30, 1998,
representing a 115% increase from 1997 to 1998.

         Net income applicable to common shareholders decreased from $2.7
million, or $0.07 per share, for the quarter ended June 30, 1997 to $1.9
million, or $0.04 per share, for the quarter ended June 30, 1998. Net income,
adjusted to exclude acquisition and integration related charges, net of the
effect of income taxes, would have been $2.7 million, or $0.07 per share, for
the quarter ended June 30, 1997, compared to $4.3 million, or $0.10 per share,
for the quarter ended June 30, 1998, representing a 57% increase from 1997 to
1998.

LIQUIDITY AND CAPITAL RESOURCES

         The Company's working capital increased $6.1 million from $94.3 million
as of December 31, 1997 to $100.4 million as of June 30, 1998. Net cash provided
by operating activities increased 55% from $1.7 million for the six months ended
June 30, 1997 to $2.7 million for the comparable period in 1998, primarily as a
result of increased interest earnings in 1998 compared to 1997.

         Net cash used in investing activities increased $9.7 million from $4.3
million for the six months ended June 30, 1997 to $14 million for the six months
ended June 30, 1998 as the Company expanded its investment in property, plant
and equipment and continued to reinvest excess cash in short-term investments.

         Net cash provided by financing activities increased $10.1 million from
net cash used of $1.1 million for the six months ended June 30, 1997 to net cash
provided of $9.0 million for the six months ended June 30, 1998 as the Company
has substantially eliminated borrowings and reliance on lines of credit in 1998
compared to 1997. Additionally, in 1998, the Company continued to experience a
significant influx of cash from exercises of stock options and warrants and
issuance of stock under its employee stock purchase plan.

         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 credit
facilities 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. 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 COMPLIANCE

         The latest versions of the Company's products are designed to be Year
2000 compliant. The Company is in the process of determining the extent to which
its earlier software products as implemented in the Company's installed customer
base are Year 2000 compliant, as well as the impact of any non-compliance on the
Company and its customers. The Company currently anticipates that any problems
resulting from non-compliant products will be addressed through a combination of
product modifications as part of planned product enhancements and migration of
customers to functionally similar products which are Year 2000 compliant.
Additional efforts are being made to modify or replace other non-compliant
software, systems and equipment used by the Company internally, including third
party software, before the year 1999. In addition, the Company is in the process
of evaluating its Year 2000 readiness with respect to both information
technology ("IT") and non-IT systems on which the Company's operations rely.
Further, the Company is aware of the risk that 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. The Company projects
that the majority of the remaining compliance effort will be absorbed with the
product enhancements planned for 1998, and thus management believes that the
Year 2000 problem will not have a material adverse impact on the Company's
business, operating results and financial condition, although there can be no
assurance to that effect. Regardess 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.

<PAGE>   15
         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. Additionally, Year 2000 issues could cause a

                                AMENDMENT TO THE
                              EMPLOYMENT AGREEMENT
                                       OF

                          ----------------------------
                        DATED _____________ _____, 19___



         THIS AMENDMENT is made this _____ day of _______, 1998, by and between
HARBINGER CORPORATION, a Georgia corporation (the "Company"), and
__________________ (the "Executive").

         A.       Purpose. The Executive is now employed by the Company pursuant
                  to an Employment Agreement dated _______________ ____, 19___
                  (the "Agreement") and the Company desires to provide an
                  incentive to the Executive to continue to devote his
                  disinterested attention and undistracted dedication to the
                  performance of his duties in the potentially disturbing
                  circumstances of a Change of Control of the Company.

         B.       Severance Benefits and Limitations on Payment. If the
                  Executive's employment with the Company is terminated by the
                  Company other than for Cause or by the Executive for Good
                  Reason within the period beginning ninety (90) days before and
                  ending one hundred and eighty (180) days after a Change of
                  Control, any stock options awarded the Executive which remain
                  outstanding and not vested as of the Date of Termination shall
                  be deemed vested and exercisable; provided, that acceleration
                  in vesting does not adversely impact the availability of
                  pooling of interests accounting treatment, as such
                  determination is made by the Board in its reasonable
                  discretion.

         (C)      Definitions. For purposes of this Amendment, the following
                  definitions shall apply:

                  1.       Change of Control. A "Change of Control" shall be
                           conclusively deemed to have occurred if (and only if)
                           any of the following shall have taken place: (i) a
                           Change of Control is reported by the Company in
                           response to either Item 6(e) of Schedule 14A of
                           Regulation 14A promulgated under the Securities
                           Exchange Act of 1934, as amended ("Exchange Act"), or
                           Item 1 of Form 8-K promulgated under the Exchange
                           Act; (ii) any person (as such term is used in Section
                           13(d) and 14(d)(2) of the Exchange Act) is or becomes
                           the beneficial owner (as defined in Rule 13d-3 under
                           the Exchange Act) directly or indirectly, of
                           securities of the Company representing forty percent
                           (40%) or more of the combined voting power of

                           the Company's then outstanding securities; or (iii)

                           majority of the Board consists of individuals who

                           election or removal, unless the election of each
                           director who was not a director at the beginning of
                           such two-year period has been approved in advance by
                           directors representing at least a majority of the
                           directors then in office who were directors at the
                           beginning of the two-year period.

                  2.       Date of Termination. "Date of Termination" means the

                                    to the Change of Control of the Company,
                                    except in connection with the termination of

                                    retirement, or Cause or as a result of the
                                    Executive's death or termination of

                            INDEMNIFICATION AGREEMENT


      THIS INDEMNIFICATION AGREEMENT is made on this _____ day of ______, 19___,
between HARBINGER CORPORATION, a Georgia corporation ("HC") and ("Indemnitee").

                              W I T N E S S E T H:

      WHEREAS, Indemnitee is a member of the Board of Directors of HC and in
such capacity performs a valuable service for HC;

      WHEREAS, HC's Bylaws (the "Bylaws") authorize HC to indemnify its officers
and directors in accordance with the Official Code of Georgia Annotated (the
"Statute");

      WHEREAS, Section 14-2-856 of the Statute specifically provides that the
indemnification provided under the other sections of the Statute is not
exclusive of any other rights in respect to indemnification or otherwise to
which those seeking indemnification may be entitled under any resolution
approved or ratified by the Shareholders by a majority of the votes entitled to
be cast;

      WHEREAS, the shareholders of HC have authorized HC to enter into contracts
with the members of the Board of Directors of HC with respect to the
indemnification of such directors; and

      WHEREAS, in order to encourage Indemnitee to continue to serve as a member
of the Board of Directors of HC and to perform other designated services for HC
at its request, HC has determined and agreed to enter into this Agreement with
Indemnitee;

      NOW, THEREFORE, in consideration of Indemnitee's continued service as a
director of HC and the performance of such other services as requested by HC,
the parties hereby agree as follows:

      1. INDEMNITY OF INDEMNITEE. HC shall defend, hold harmless and indemnify
Indemnitee to the full extent permitted by the provisions of the Statute, as
currently in effect or as it may hereafter be amended, or by the provisions of
any other statute authorizing or permitting such indemnification, whether
currently in effect or hereafter adopted.

      2. ADDITIONAL INDEMNITY. Subject to the provisions of Section 3 hereof, HC
shall defend, hold harmless and indemnify Indemnitee in the event Indemnitee
was, is, or is threatened to be made a named defendant or respondent, in any
action, suit or proceeding, whether civil, criminal, administrative or
investigative and whether formal or informal (including any such action, suit or
proceeding brought by or in the right of HC), by reason of the fact that he is
or was a director of HC, or is or was serving at the request of HC as a director
of another corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise, against any obligation to pay a judgment, settlement,
penalty, fine (including an excise tax assessed with respect to an employment
benefit plan), expenses (including attorneys' fees), and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding. For purposes of this Section 2, Indemnitee shall be
considered to be serving an employee benefit plan at the request of HC if his
duties to HC also impose duties on, or otherwise involve services by, him to the
plan or to participants in or beneficiaries of the plan.

      3. LIMITATIONS ON ADDITIONAL INDEMNITY. No indemnity pursuant to Section 2
hereof shall be paid by HC to the extent of any liabilities incurred in a
proceeding in which Indemnitee is adjudged liable to HC or is subjected to
injunctive relief in favor of HC:

         (1) for any appropriation in violation of his duties, of any business
opportunity of HC;

<PAGE>   2

         (2) for acts or omissions which involve intentional misconduct or a
knowing violation of law;

         (3) for the types of liability set forth in O.C.G.A. ss.14-2-832; or

         (4) for any transaction from which Indemnitee received any improper
personal benefit.

      4. NOTIFICATION AND DEFENSE OF CLAIM.

         (a) Promptly after receipt by Indemnitee of notice of the commencement
of any action, suit or proceeding, Indemnitee will, if a claim in respect
thereto is to be made against HC under this Agreement, notify HC of the
commencement thereof, but the failure to so notify HC will not relieve it from
any liability which it may have to Indemnitee otherwise under this Agreement.
With respect to any such action, suit or proceeding as to which Indemnitee so
notifies HC:

             (i) HC will be entitled to participate therein at its own expense;
and

             (ii) except as otherwise provided below, to the extent that it may
desire, HC may assume the defense thereof.

         (b) After notice from HC to Indemnitee of its election to assume the
defense thereof, HC will not be liable to Indemnitee under this Agreement for
any legal or other expenses subsequently incurred by Indemnitee in connection
with the defense thereof other than reasonable costs of investigation or as
otherwise provided below. Indemnitee shall have the right to employ counsel of
his choosing in such action, suit or proceeding but the fees and expenses of
such counsel incurred after notice from HC of its assumption of the defense
thereof shall be at the expense of Indemnitee unless (i) the employment of
counsel by Indemnitee has been authorized in writing by HC, (ii) HC and
Indemnitee shall reasonably conclude that there may be a conflict of interest
between HC and Indemnitee in the conduct of the defense of such action, or (iii)
HC shall not in fact have employed counsel to assume the defense of such action,
in each of which cases the reasonable fees and expenses of Indemnitee's counsel
shall be paid by HC.

         (c) HC shall not be liable to Indemnitee under this Agreement for any
amounts paid in settlement of any threatened or pending action, suit or
proceeding without its prior written consent. HC shall not settle any such
action, suit or proceeding in any manner which would impose any penalty or
limitation on Indemnitee without Indemnitee's prior written consent. Neither HC
nor Indemnitee will unreasonably withhold his or its consent to any proposed
settlement.

      5. PREPAYMENT OF EXPENSES. Unless Indemnitee otherwise elects, expenses
incurred in defending any civil or criminal action, suit or proceeding shall be
paid by HC in advance of the final disposition of such action, suit or
proceeding upon receipt by HC of a written affirmation of Indemnitee's good
faith belief that his conduct does not constitute behavior of the kind described
in Section 3 of this Agreement and Indemnitee furnishes HC a written
undertaking, executed personally or on his behalf, to repay any advances if it
is ultimately determined that he is not entitled to be indemnified by HC under
this Agreement.

      6. CONTINUATION OF INDEMNITY. All agreements and obligations of HC
contained in this Agreement shall continue during the period Indemnitee is a
member of the Board of Directors of HC and shall continue thereafter so long as
Indemnitee shall be subject to any action, suit or proceeding, whether civil,
criminal, administrative or investigative, and whether formal or informal, by
reason of the fact that Indemnitee was an officer of HC, or is or was serving at
the request of HC as a director of another corporation, partnership, joint
venture, trust or other enterprise.

      7. RELIANCE. HC has entered into this Agreement in order to induce
Indemnitee to continue as a member of the Board of Directors of HC and
acknowledges that Indemnitee is relying upon this Agreement in continuing in
such capacity.

      8. SEVERABILITY. Each of the provisions of this Agreement is a separate
and distinct agreement and independent of the others, so that if any provision
hereof shall be held to be invalid or unenforceable for any reason, such
invalidity or unenforceability shall not affect the validity or enforceability
of the other provisions hereof.

      9. GENERAL.

         (a) This Agreement shall be governed by and construed in accordance
with the laws of the State of Georgia.

         (b) Neither this Agreement nor any rights or obligations hereunder
shall be assigned or transferred by Indemnitee.

         (c) This Agreement shall be binding upon Indemnitee and upon HC, its
successors and assigns, including successors by merger or consolidation, and
shall inure to the benefit of Indemnitee, his heirs, personal representatives
and permitted assigns and to the benefit of HC, its successors and assigns.

         (d) No amendment, modification or termination of this Agreement shall
be effective unless in writing signed by both parties hereof.

      IN WITNESS WHEREOF, the parties hereto have executed this Agreement on and
as of the day and year first above written.

                            INDEMNIFICATION AGREEMENT


      THIS INDEMNIFICATION AGREEMENT ("Agreement") is made on this ____ day of
________, 19___, between HARBINGER CORPORATION, a Georgia corporation ("HC") and
("Indemnitee").

                              W I T N E S S E T H:

      WHEREAS, Indemnitee is a member of the Board of Directors of HC and in
such capacity performs a valuable service for HC;

      WHEREAS, HC's Bylaws (the "Bylaws") authorize HC to indemnify its officers
and directors in accordance with the Official Code of Georgia Annotated (the
"Statute"); and

      WHEREAS, in order to encourage Indemnitee to continue to serve as a member
of the Board of Directors of HC and to perform other designated services for HC
at its request, HC has determined and agreed to enter into this Agreement with
Indemnitee;

      NOW, THEREFORE, in consideration of Indemnitee's continued service as a
director of HC and the performance of such other services as requested by HC,
the parties hereby agree as follows:

      1. INDEMNITY OF INDEMNITEE. HC shall defend, hold harmless and indemnify
Indemnitee to the full extent permitted by the provisions of the Statute, as
currently in effect or as it may hereafter be amended, or by the provisions of
any other statute authorizing or permitting such indemnification, whether
currently in effect or hereafter adopted.

      2. ADDITIONAL INDEMNITY.

         (a) Except as provided in subsections (d) and (e) of this Section 2
below, HC shall indemnify Indemnitee to the fullest extent permitted by the
Statute, and to the extent that applicable law from time to time in effect shall
permit indemnification that is broader than provided in this Agreement, then to
the maximum extent authorized by law, should Indemnitee be made a party to a
proceeding because he is or was a member of the Board of Directors against
liability incurred by him in the proceeding if Indemnitee acted in a manner he
believed in good faith to be in or not opposed to the best interests of HC and,
in the case of any criminal proceeding, he had no reasonable cause to be believe
his conduct was unlawful.

         (b) Indemnitee's conduct with respect to an employee benefit plan for a
purpose he believed in good faith to be in the interests of the participants in
and beneficiaries of the plan is conduct that satisfies the requirement of
subsection (a) of this Section 2 above.

         (c) The termination of a proceeding by judgment, order, settlement or
conviction, or upon a plea of nolo contendere or its equivalent shall not, of
itself, be determinative that Indemnitee did not meet the standard of conduct
set forth in subsection (a) of this Section 2 above.

         (d) HC shall not indemnify Indemnitee under this Agreement:

             (1) In connection with a proceeding by or in the right of HC in
which Indemnitee was adjudged liable to HC; or

             (2) In connection with any other proceeding in which Indemnitee was
adjudged liable on the basis that personal benefit was improperly received by
him unless, and then only to the extent that,  a 

<PAGE>   2

court of competent jurisdiction determines pursuant to Section 14-2-854 of the
Statute that in view of the circumstances of the case, Indemnitee is fairly and
reasonably entitled to indemnification.

         (e) Indemnification permitted under this Agreement in connection with a
proceeding by or in the right of HC is limited to reasonable expenses incurred
in connection with the proceeding.

      3. DETERMINATION AND AUTHORIZATION OF INDEMNIFICATION.

         (a) HC shall not indemnify Indemnitee under Section 2 of this Agreement
above unless a determination has been made in the specific case that
indemnification of Indemnitee is permissible in the circumstances because he has
met the standard of conduct set forth in subsection (a) of Section 2 of this
Agreement above; provided, however, that regardless of the result or absence of
any such determination, and unless limited by the Articles of Incorporation of
HC, to the extent that Indemnitee has been successful, on the merits or
otherwise, in the defense of any proceeding to which he was a party, or in
defense of any claim, issue or matter therein, because he is or was a member of
the Board of Directors, HC shall indemnify Indemnitee against reasonable
expenses incurred by him in connection therewith.

         (b) The determination specified in subsection (a) of this Section 3
shall be made:

             (1) By the Board of Directors of HC by majority vote of a quorum
consisting of Directors not at the time parties to the proceeding;

             (2) If a quorum cannot be obtained under paragraph (1) of this
subsection (b) of this Section 3, by majority vote of a committee duly
designated by the Board of Directors (in which designation Directors who are
parties may participate), consisting solely of two or more Directors not at the
time parties to the proceeding;

             (3) By special legal counsel:

                 (A) Selected by the Board of Directors or its committee in the
manner prescribed in paragraphs (1) and (2) of this subsection (b) of this
Section 3; or

                 (B) If a quorum of the Board of Directors cannot be obtained
under paragraph (1) of this subsection (b) of this Section 3 and a committee
cannot be designated under paragraph (2) of this subsection (b) of this Section
3, selected by a majority vote of the full Board of Directors (in which
selection Directors who are parties may participate); or

             (4) By the shareholders of HC, but shares owned by or voted under
the control of Directors who are at the time parties to the proceeding may not
be voted on the determination.

         (c) Evaluation as to reasonableness of expenses shall be made in the
same manner as the determination that indemnification is permissible, except
that if the determination is made by special legal counsel, evaluation as to
reasonableness of expenses shall be made by those entitled under paragraph (3)
of subsection (b) of this Section 3 to select counsel.

         (d) If the determination to be made pursuant to Section 3(a) above has
not been made within thirty (30) days following Indemnitee's written request for
indemnification, then Indemnitee shall be deemed to have met the standard of
conduct set forth in subsection (a) of Section 3 of this Agreement. If the
determination to be made pursuant to Section 3(c) above has not been made within
thirty (30) days following Indemnitee's written request for indemnification for,
or advancement of, expenses, then the expenses claimed shall be deemed
reasonable.

      4. NOTIFICATION AND DEFENSE OF CLAIM.

         (a) Promptly after receipt by Indemnitee of notice of the commencement
of any action, suit or proceeding, Indemnitee will, if a claim in respect
thereto is to be made against HC under this Agreement, notify HC of the
commencement thereof, but the failure to so notify HC will not relieve it from
any liability which it may have to Indemnitee otherwise under this Agreement.
With respect to any such action, suit or proceeding as to which Indemnitee so
notifies HC:

             (1) HC will be entitled to participate therein at its own expense;
and

             (2) except as otherwise provided below, to the extent that it may
desire, HC may assume the defense thereof.

         (b) After notice from HC to Indemnitee of its election to assume the
defense thereof, HC will not be liable to Indemnitee under this Agreement for
any legal or other expenses subsequently incurred by Indemnitee in connection
with the defense thereof other than reasonable costs of investigation or as
otherwise provided below. Indemnitee shall have the right to employ counsel of
his choosing in such action, suit or proceeding but the fees and expenses of
such counsel incurred after notice from HC of its assumption of the defense
thereof shall be at the expense of Indemnitee unless (i) the employment of
counsel by Indemnitee has been authorized in writing by HC, (ii) HC and
Indemnitee shall reasonably conclude that there may be a conflict of interest
between HC and Indemnitee in the conduct of the defense of such action, or (iii)
HC shall not in fact have employed counsel to assume the defense of such action,
in each of which cases the reasonable fees and expenses of Indemnitee's counsel
shall be paid by HC.

         (c) HC shall not be liable to Indemnitee under this Agreement for any
amounts paid in settlement of any threatened or pending action, suit or
proceeding without its prior written consent. HC shall not settle any such
action, suit or proceeding in any manner which would impose any penalty or
limitation on Indemnitee without Indemnitee's prior written consent. Neither HC
nor Indemnitee will unreasonably withhold his or its consent to any proposed
settlement.

      5. PREPAYMENT OF EXPENSES.

         (a) HC shall pay for or reimburse the reasonable expenses incurred by
Indemnitee resulting from Indemnitee having been a party to a proceeding in
advance of final disposition of the proceeding if:

             (1) Indemnitee furnishes HC with a written affirmation of his good
faith belief that he has met the standard of conduct set forth in subsection (a)
of Section 2 above; and

             (2) Indemnitee furnishes HC with a written undertaking, executed
personally or on his behalf, to repay any advances if it is ultimately
determined that he is not entitled to indemnification under this Agreement.

         (b) The undertaking required by paragraph (2) of subsection (a) of this
Section 5 must be an unlimited general obligation of Indemnitee but need not be
secured and may be accepted without reference to financial ability to make
repayment.

      6. CONTINUATION OF INDEMNITY. All agreements and obligations of HC
contained in this Agreement shall continue during the period Indemnitee is a
member of the Board of Directors of HC and shall continue thereafter so long as
Indemnitee shall be subject to any action, suit or proceeding, whether civil,
criminal, administrative or investigative, and whether formal or informal, by
reason of the fact that Indemnitee was an officer of HC, or is or was serving at
the request of HC as a director of another corporation, partnership, joint
venture, trust or other enterprise.

      7. RELIANCE. HC has entered into this Agreement in order to induce
Indemnitee to continue as a member of the Board of Directors of HC and
acknowledges that Indemnitee is relying upon this Agreement in continuing in
such capacity.

      8. SEVERABILITY. Each of the provisions of this Agreement is a separate
and distinct agreement and independent of the others, so that if any provision
hereof shall be held to be invalid or unenforceable for any reason, such
invalidity or unenforceability shall not affect the validity or enforceability
of the other provisions hereof.

      9. GENERAL.

         (a) This Agreement shall be governed by and construed in accordance
with the laws of the State of Georgia.

         (b) Neither this Agreement nor any rights or obligations hereunder
shall be assigned or transferred by Indemnitee.

         (c) This Agreement shall be binding upon Indemnitee and upon HC, its
successors and assigns, including successors by merger or consolidation, and
shall inure to the benefit of Indemnitee, his heirs, personal representatives
and permitted assigns and to the benefit of HC, its successors and assigns.

         (d) No amendment, modification or termination of this Agreement shall
be effective unless in writing signed by both parties hereof.

      IN WITNESS WHEREOF, the parties hereto have executed this Agreement on and
as of the day and year first above written.

                   AMENDED AND RESTATED 1993 STOCK OPTION PLAN
                        FOR (DUTCH) NONEMPLOYEE DIRECTORS


                  THIS STOCK OPTION AGREEMENT (the "Option Agreement") is made
and entered into as of the date set forth below, by and between HARBINGER
CORPORATION (hereinafter called the "Company"), a corporation organized and
existing under the laws of the State of Georgia, and the undersigned, an
individual resident of the state designated below (hereinafter called
"Optionee").

                  The Company has adopted the "Harbinger Corporation Amended and
Restated 1993 Stock Option Plan for Nonemployee Directors" (the "Plan"). This
Option Agreement is being made pursuant to the Plan and capitalized terms used
herein shall have the same meanings as those terms have in the Plan unless the
context in which these terms are used herein requires otherwise or the terms are
otherwise defined herein. The date of the grant of the option under this Option
Agreement is as of the date specified below (the "Option Date").

         1.       GRANT OF OPTION. The Company hereby grants to Optionee an
option to purchase the number of shares of $.0001 par value Common Stock of the
Company (the "Shares") designated below ("Option Shares"), subject to the right
to repurchase . Any portion of the option not exercised by Optionee as provided
herein will expire on the day prior to the fifth anniversary of the Option Date
unless sooner terminated as provided herein. Any option share subject to a
repurchase right as of the Annual Meeting of Shareholders following the date
hereof shall expire on the date of such meeting. The stock issued on the
exercise of this option, when paid for as herein provided, will be fully paid
and nonassessable.

         2.       EXERCISE OF OPTION. This option is fully vested and may be
exercised only during the period beginning on the Option Date and ending on the
day prior to the fifth anniversary date hereof (the "Term") described below. For
purposes of this Option Agreement, the "Repurchase Period" for an option shall
mean, for an Annual Grant, the approximate twelve (12) month period beginning
upon the date of the Annual Grant and ending on the date of the next Annual
Meeting, and for an Interim Grant, the period beginning upon the date of the
Interim Grant and ending on the date of the next Annual Meeting.

                  (a)      Annual Grants: Options granted as an Annual Grant
(see below) shall no longer be subject to repurchase as follows:

                  (1)      If Optionee attends one regular quarterly meeting of
                           the Board of Directors ("Board") during the
                           Repurchase Period, then the option shall no longer be
                           subject to repurchase immediately thereafter as to
                           twenty-five percent (25%) of


<PAGE>   4

                           the Option Shares, minus the number of Shares, if
                           any, as to which the option has been previously
                           exercised;

                  (2)      If Optionee attends two regular quarterly meetings
                           during the Repurchase Period, then the option shall
                           no longer be subject to repurchase immediately after
                           the second meeting as to fifty percent (50%) of the
                           Option Shares, minus the number of Shares, if any, as
                           to which the option has been previously exercised;

                  (3)      If Optionee attends three regular quarterly meetings
                           during the Repurchase Period, then the option shall
                           no longer be subject to repurchase immediately after
                           the third meeting as to seventy-five percent (75%) of
                           the Option Shares, minus the number of Shares, if
                           any, as to which the option has been previously
                           exercised; and

                  (4)      If Optionee attends four regular quarterly meetings
                           during the Repurchase Period, then the option shall
                           no longer be subject to repurchase immediately after
                           the fourth meeting as to all of the Option Shares,
                           minus the number of Shares, if any, as to which the
                           option has been previously exercised.

                  (b) Interim Grants: Options granted as an Interim Grant (see
below) shall no longer be subject to repurchase as follows:

                  (1)      If the fraction determined in Section 5.2.2 of the
                           Plan is three fourths (75%), then one third (33.3%)
                           of the Option Shares shall no longer be subject to
                           repurchase immediately following the attendance by
                           Optionee at a regular quarterly meeting of the Board
                           during the Repurchase Period, and an additional
                           one-third (33.3%) of the Option Shares shall no
                           longer be subject to repurchase following attendance
                           by Optionee at each of two (2) subsequent regular
                           quarterly meetings during the Repurchase Period, such
                           that the option shall no longer be subject to
                           repurchase immediately after attendance by Optionee
                           at the third regular quarterly meeting during the
                           Repurchase Period as to all of the Option Shares
                           subject to the option.

                  (2)      If the fraction determined in Section 5.2.2 of the
                           Plan is one half (50%), then one half (50%) of the
                           Option Shares shall no longer be subject to
                           repurchase immediately following the attendance by
                           Optionee at a regular quarterly meeting of the Board
                           during the Repurchase Period, and the remaining one
                           half (50%) of the Option Shares shall no longer be
                           subject to repurchase immediately after attendance by
                           Optionee at a second regular quarterly meeting during
                           the Repurchase Period, as to all of the Option Shares
                           subject to the option.

                  (3)      If the fraction determined in Section 5.2.2 of the
                           Plan is one quarter (25%), then all (100%) of the
                           Option Shares shall no longer be subject to
                           repurchase immediately following the attendance by
                           Optionee at a regular quarterly meeting of the Board
                           during the Repurchase Period.

                  The terms contained in the Plan are incorporated into and made
a part of this Option Agreement, and this Option Agreement shall be governed by
and construed in accordance with the Plan.


<PAGE>   5

A "regular quarterly meeting" shall refer to a regular meeting (including an
Annual Meeting or a special meeting held in lieu of a regular meeting) of the
Board held on a quarterly basis, as determined by the Chief Executive Officer of
the Company. In order to "attend" a meeting Optionee must be present as a
Director at the meeting in person or by telephone connection for the entire
period of the meeting and any adjournments thereof.

                  Each exercise of the option shall be by written notice in the
form of an exercise agreement provided by the Board to the President or
principal financial officer of the Company at its principal place of business,
accompanied by payment in cash, by bank-certified, cashier's or personal check
in the amount of the purchase price for the number of the Shares purchased. The
date of each exercise of this option shall be the date upon which the notice is
received by the appropriate officer.

                  The Company shall not be obligated to sell or issue any Shares
pursuant to the option unless the issuance of such Shares is at that time
effectively registered or exempt from registration under the Securities Act of
1933, as amended, and any other applicable securities laws. In connection
therewith, the Company may require from Optionee at the time of exercise
reasonable representations and warranties with respect to the investment intent
of Optionee and Optionee's status as an investor in the Shares in order to
qualify for exemptions from registration under state or federal securities laws.

                  Within a reasonable time after receipt of the notice of
exercise, the Company will take steps to ascertain compliance with this Option
Agreement. The Company shall then cause certificates representing the Shares for
the option exercised to be delivered as soon as reasonably possible, provided,
however, that if any law, regulation, or agreement requires the Company to take
action with respect to the Shares purchased prior to issuance, the date of
issuance of the Shares shall be extended for the period necessary to take such
action and comply with such law, regulation or agreement.

         3.       ADMINISTRATION. This Agreement shall be administered,
construed and interpreted by the Board with reference to the terms, conditions,
and interpretive provisions of the Plan.

         4.       PURCHASE PRICE. The purchase price per Option Share shall be
as designated below ("Exercise Price"), which is equal to or greater than 100%
of the fair market value of a share of Common Stock as of the Option Date.

         5.       TERMINATION OF SERVICE OR DEATH. In the event Optionee, during
his or her life, ceases to be an Eligible Director for any reason, any
unexercised portion of the option shall terminate one (1) year after termination
of Optionee's status as an Eligible Director due to disability (within the
meaning of Section 22(e)(3) of the Internal Revenue Code of 1986, as amended)
and thirty (30) days after the termination of Optionee's status as an Eligible
Director for any other reason, but in no event after the expiration of the term
of the option; provided further, however, that (a) with respect to any
installment of the option that is subject to a right of repurchase at the time
of termination of Optionee's status as an Eligible Director, the applicable
extension period shall not, unless otherwise provided by the Board, operate to
permit such installment to become no longer subject to a right of repurchase
within such period; (b) with respect to any installment of the option that was
no longer subject to a right of repurchase at the time of termination of
service, the applicable extension period shall not operate to permit the
exercise of such installment after the expiration of the period within which
such installment may otherwise be exercised; and (c) the applicable extension
period shall not operate to permit the exercise of an option if the service of
Optionee is terminated prior to the term during which the option would otherwise
have become no longer subject to a right of repurchase.


<PAGE>   6

                  In the event of the death of Optionee while Optionee is an
Eligible Director, but before the expiration of this option, the personal
representatives, heirs or legatees of Optionee may exercise the option held by
Optionee which was no longer subject to a right of repurchase on the date of
Optionee's death. The personal representatives, heirs or legatees must exercise
any such option within thirty (30) days after the date of the death of Optionee
and in any event prior to the date of expiration of the option, and such
exercise otherwise shall be subject to the terms and conditions of this Option
Agreement and the Plan; provided, however, that with respect to any installment
of the option that was subject to a right of repurchase on the date of
Optionee's death, the extension period shall not, unless otherwise provided by
the Board, operate to permit such installment to become no longer subject to a
right of repurchase within such period.

         6.       NO RIGHTS IN OPTION SHARES. Optionee shall have no rights as a
shareholder in respect of Shares covered by this Option Agreement until the date
of issuance of the Shares to him or her and only after the Shares are fully
paid. Optionee shall have no rights with respect to such Shares not expressly
conferred by this Option Agreement.

         7.       COMPANY'S REPURCHASE OPTION. If Optionee should cease to be an
Eligible Director, the Company or its assignee shall have the option to
repurchase that number of Shares which then remains subject to a right of
repurchase at a price equal to the exercise price per share indicated below as
the Exercise Price during the term of this Option (the "Repurchase Option").
Each Share shall be deemed to be an unvested Share until the date that such
Share is no longer subject to the Repurchase Option and shall thereafter be
deemed to be a vested Share. At any time within three months after the
expiration or termination of this Option, the Company or its assignee may elect
to repurchase any or all unvested Shares at the Optionee's exercise price by
giving Optionee or his representative written notice of exercise of the
Repurchase Option. The repurchase price per Share may be paid by check or by
cancellation of indebtedness, if any.

         8.       NONASSIGNABILITY. This option shall not be encumbered or
transferred in whole or in part except by will or the laws of descent and
distribution, and is exercisable during the lifetime of Optionee only by him or
her, except as expressly permitted by the Board.

                  In consideration for the grant of this option, Optionee
promises to use his or her best efforts in furtherance of the Company's business
and prospects and in the exercise of his or her duties as a member of the Board
of Directors of the Company.

                   AMENDED AND RESTATED 1993 STOCK OPTION PLAN
                            FOR NONEMPLOYEE DIRECTORS


                  THIS STOCK OPTION AGREEMENT (the "Option Agreement") is made
and entered into as of the date set forth below, by and between HARBINGER
CORPORATION (hereinafter called the "Company"), a corporation organized and
existing under the laws of the State of Georgia, and the undersigned, an
individual resident of the state designated below (hereinafter called
"Optionee").

                  The Company has adopted the "Harbinger Corporation Amended and
Restated 1993 Stock Option Plan for Nonemployee Directors" (the "Plan"). This
Option Agreement is being made pursuant to the Plan and capitalized terms used

         1.       GRANT OF OPTION. The Company hereby grants to Optionee an
option to purchase the number of shares of $.0001 par value Common Stock of the

option not exercised by Optionee as provided herein will expire on the seventh
anniversary of the Option Date unless sooner terminated as provided herein. The
stock issued on the exercise of this option, when paid for as herein provided,

         2.       EXERCISE OF OPTION. This option shall become vested and may be
exercised only during the period beginning on the Option Date and ending on the

                           Period, then the option shall be exercisable
                           immediately thereafter as to twenty-five percent
                           (25%) of the Option Shares, minus the number of
                           Shares, if any, as to which the option has been
                           previously exercised;


<PAGE>   9

                  (2)      If Optionee attends two regular quarterly meetings
                           during the Vesting Period, then the option shall be
                           exercisable immediately after the second meeting as
                           to fifty percent (50%) of the Option Shares, minus
                           the number of Shares, if any, as to which the option
                           has been previously exercised;

                  (3)      If Optionee attends three regular quarterly meetings
                           during the Vesting Period, then the option shall be

                           seventy-five percent (75%) of the Option Shares,
                           minus the number of Shares, if any, as to which the
                           option has been previously exercised; and

                  (4)      If Optionee attends four regular quarterly meetings
                           during the Vesting Period, then the option shall be
                           exercisable immediately after the fourth meeting as
                           to all of the Option Shares, minus the number of
                           Shares, if any, as to which the option has been
                           previously exercised.

                  (b)      Interim Grants: Options granted as an Interim Grant
(see below) shall become vested as follows:

                  (1)      If the fraction determined in Section 5.2.2 of the
                           Plan is three fourths (75%), then one third (33.3%)
                           of the Option Shares shall become exercisable
                           immediately following the attendance by Optionee at a
                           regular quarterly meeting of the Board during the
                           Vesting Period, and an additional one-third (33.3%)
                           of the Option Shares shall become exercisable
                           following attendance by Optionee at each of two (2)
                           subsequent regular quarterly meetings during the
                           Vesting Period, such that the option shall be
                           exercisable immediately after attendance by Optionee
                           at the third regular quarterly meeting during the
                           Vesting Period as to all of the Option Shares subject
                           to the option.

                  (2)      If the fraction determined in Section 5.2.2 of the
                           Plan is one half (50%), then one half (50%) of the
                           Option Shares shall be exercisable immediately
                           following the attendance by Optionee at a regular
                           quarterly meeting of the Board during the Vesting
                           Period, and the remaining one half (50%) of the
                           Option Shares shall be exercisable immediately after
                           attendance by Optionee at a second regular quarterly
                           meeting during the Vesting Period, as to all of the
                           Option Shares subject to the option.

                  (3)      If the fraction determined in Section 5.2.2 of the
                           Plan is one quarter (25%), then all (100%) of the

                           quarterly meeting of the Board during the Vesting
                           Period.

                  The terms contained in the Plan are incorporated into and made
a part of this Option Agreement, and this Option Agreement shall be governed by
and construed in accordance with the Plan. A "regular quarterly meeting" shall

<PAGE>   10

                  Each exercise of the option shall be by written notice in the
form of an exercise agreement provided by the Board to the President or
principal financial officer of the Company at its principal place of business,
accompanied by payment in cash, by bank-certified, cashier's or personal check
in the amount of the purchase price for the number of the Shares purchased. The
date of each exercise of this option shall be the date upon which the notice is
received by the appropriate officer.

                  The Company shall not be obligated to sell or issue any Shares
pursuant to the option unless the issuance of such Shares is at that time
effectively registered or exempt from registration under the Securities Act of
1933, as amended, and any other applicable securities laws. In connection
therewith, the Company may require from Optionee at the time of exercise
reasonable representations and warranties with respect to the investment intent
of Optionee and Optionee's status as an investor in the Shares in order to
qualify for exemptions from registration under state or federal securities laws.

                  Within a reasonable time after receipt of the notice of
exercise, the Company will take steps to ascertain compliance with this Option
Agreement. The Company shall then cause certificates representing the Shares for
the option exercised to be delivered as soon as reasonably possible, provided,
however, that if any law, regulation, or agreement requires the Company to take
action with respect to the Shares purchased prior to issuance, the date of
issuance of the Shares shall be extended for the period necessary to take such
action and comply with such law, regulation or agreement.

         3.       ADMINISTRATION. This Agreement shall be administered,
construed and interpreted by the Board with reference to the terms, conditions,
and interpretive provisions of the Plan.

         4.       PURCHASE PRICE. The purchase price per Option Share shall be

of the fair market value of a share of Common Stock as of the Option Date.

         5.       TERMINATION OF SERVICE OR DEATH. In the event Optionee, during
his or her life, ceases to be an Eligible Director for any reason, any
unexercised portion of the option shall terminate one (1) year after termination
of Optionee's status as an Eligible Director due to disability (within the
meaning of Section 22(e)(3) of the Internal Revenue Code of 1986, as amended)
and thirty (30) days after the termination of Optionee's status as an Eligible
Director for any other reason, but in no event after the expiration of the term
of the option; provided further, however, that (a) with respect to any
installment of the option that had not become exercisable at the time of
termination of Optionee's status as an Eligible Director, the applicable
extension period shall not, unless otherwise provided by the Board, operate to
permit such installment to become exercisable within such period; (b) with
respect to any installment of the option that had become exercisable at the time
of termination of service, the applicable extension period shall not operate to
permit the exercise of such installment after the expiration of the period
within which such installment may otherwise be exercised; and (c) the applicable
extension period shall not operate to permit the exercise of an option if the
service of Optionee is terminated prior to the term during which the option
would otherwise have been exercisable.

                  In the event of the death of Optionee while Optionee is an
Eligible Director, but before the expiration of this option, the personal
representatives, heirs or legatees of Optionee may exercise the option held by
Optionee on the date of Optionee's death. The personal representatives, heirs or
legatees must exercise any such option within thirty (30) days after the date of
the death of Optionee and in any event prior to the date of expiration of the
option, and such exercise otherwise shall be subject to the terms and conditions
of this Option Agreement and the Plan; provided, however, that with respect to
any installment of the option that had not become vested and exercisable on the
date of Optionee's death, the 


<PAGE>   11

extension period shall not, unless otherwise provided by the Board, operate to
permit such installment to become vested and exercisable within such period.

         6.       NO RIGHTS IN OPTION SHARES. Optionee shall have no rights as a
shareholder in respect of Shares covered by this Option Agreement until the date
of issuance of the Shares to him or her and only after the Shares are fully
paid. Optionee shall have no rights with respect to such Shares not expressly
conferred by this Option Agreement.

         7.       NONASSIGNABILITY. This option shall not be encumbered or
transferred in whole or in part except by will or the laws of descent and
distribution, and is exercisable during the lifetime of Optionee only by him or
her, except as expressly permitted by the Board.

                  In consideration for the grant of this option, Optionee
promises to use his or her best efforts in furtherance of the Company's business
and prospects and in the exercise of his or her duties as a member of the Board
of Directors of the Company.

                  IN WITNESS WHEREOF, the parties hereunto have set their hands
