REVENUES

The Company's revenues consist of software license revenues and service
revenues. Software license revenues for periods subsequent to December 31, 1997,
are recognized in accordance with the American Institute of Certified Public
Accountants' Statement of Position ("SOP") 97-2, Software Revenue Recognition.
Under SOP 97-2, software license revenues are recognized upon execution of a
contract and delivery of software, provided that the license fee is fixed and
determinable, no significant production, modification or customization of the
software is required and collection is considered probable by management. For
periods prior to December 31, 1997, software license revenues were recognized in
accordance with SOP 91-1, Software Revenue Recognition. Under SOP 91-1, software
license revenues were recognized upon execution of a contract and shipment of
the software, provided that no significant vendor obligations remained
outstanding, amounts were due within one year and collection was considered
probable by management. The appli-


                                                                              15
<PAGE>   2
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS (CONTINUED)

cation of SOP 97-2 had no impact on the Company's consolidated financial
statements for the year ended December 31, 1998. In 1999, software license
revenues will be recognized in accordance with SOP 97-2, as modified by SOP
98-9, Modification of SOP 97-2, Software Revenue Recognition with respect to
Certain Transactions. The Company believes it is currently in compliance with
SOP 97-2, as modified by SOP 98-9. Service revenues are recognized as the
services are performed. Maintenance revenues are derived from customer support
agreements generally entered into in connection with initial license sales and
subsequent renewals. Maintenance revenues are recognized ratably over the term
of the maintenance period. Payments for maintenance fees are generally made in
advance.

INTERNATIONAL REVENUES

The Company recognized $7.1 million, $2.4 million and $1.0 million of revenues
from international locations in 1998, 1997 and 1996, representing 18.1%, 12.3%
and 10.7% of total revenues, respectively. The Company's revenues from
international locations were primarily generated from customers located in
Europe. Revenues from customers located in Europe accounted for 13.2%, 10.3% and
10.1% of total revenues in 1998, 1997 and 1996, respectively. The continued
increase in revenues from international locations as a percentage of total
revenues is primarily the result of the Company's expansion of its operations
outside the United States, which has included both the hiring of additional
personnel as well as the establishment of additional reseller agreements. The
Company believes that continued growth and profitability will require further
expansion of its sales in international markets. The Company expects to commit
additional time and development resources to customizing its products and
services for selected international markets.

TOTAL REVENUES  

Total revenues were $39.5 million, $19.6 million and $9.0 million in 1998, 1997
and 1996, respectively, representing increases of 101.7% from 1997 to 1998 and
117.3% from 1996 to 1997.

LICENSE REVENUES

The Company's license revenues are derived from the licensing of software
products. License revenues were $33.0 million, $17.3 million and $7.8 million,
in 1998, 1997 and 1996, respectively, representing increases of 90.4% from 1997
to 1998 and 121.1% from 1996 to 1997. License revenues accounted for 83.7%,
88.6% and 87.1% of total revenues in 1998, 1997 and 1996, respectively. The
increase in license revenues resulted from increased sales to new customers and
additional sales to existing customers for new products and upgrades of existing
licenses. There were no price increases for products during 1998.

SERVICE REVENUES

The Company's service revenues consist of fees for maintenance, training and
professional services. Service revenues were $6.4 million, $2.2 million and $1.2
million in 1998, 1997 and 1996, respectively, representing increases of 189.9%
from 1997 to 1998 and 91.5% from 1996 to 1997. Service revenues accounted for
16.3%, 11.4% and 12.9% of total revenues in 1998, 1997 and 1996, respectively.
The increase in service revenues was attributed to an increase in revenue from
maintenance contracts, training and professional services for new and existing
customers.

COST OF REVENUES

Cost of revenues include expenses associated with royalty costs, production,
fulfillment and product documentation, along with personnel costs associated
with providing customer support in connection with maintenance, training and
professional services contracts. Royalty costs are comprised of third- party
software costs. Cost of revenues were $4.6 million, $2.9 million and $2.0
million in 1998, 1997 and 1996, respectively, representing increases of 59.9%
from 1997 to 1998 and 46.9% from 1996 to 1997. Cost of revenues accounted for
11.6%, 14.7% and 21.7% of total revenues in 1998, 1997 and 1996, respectively,
resulting in gross margins of 88.4%, 85.3% and 78.3% in each respective period.
The increase in cost of revenues was primarily the result of increased spending
in customer support to be more responsive to growing customer needs. The
improvement in the gross margin percentages were attributable to lower royalty
unit costs associated with the higher sales volumes during the 1998 periods and
a one-time charge of $400,000 for the write-off of inventories associated with
the discontinuation of the TRAKKER(R) product line during 1996.

RESEARCH AND DEVELOPMENT EXPENSES

Research and development expenses consist primarily of personnel costs
associated with software development. Research and development expenses were
$7.2 million, $4.6 million and $3.9 million in 1998, 1997 and 1996,
respectively, representing an increase of 55.6% from 1997 to 1998 and 17.7% from
1996 to 1997. Research and development expenses accounted for 18.3%, 23.7% and
43.7% of total revenues in 1998, 1997 and 1996, respectively. The 


16

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS (CONTINUED)


increase in absolute dollars was primarily due to increased headcount in
research and development from 40 to 55 people from 1997 to 1998 and 34 to 40
people from 1996 to 1997. The Company's product architecture and higher revenue
base have allowed the Company to introduce new products at lower incremental
costs thereby reducing research and development expenses as a percentage of
revenues. The Company anticipates that it will continue to commit substantial
resources to research and development in the future and that product development
expenses may increase in absolute dollars in future periods.

SALES AND MARKETING EXPENSES

Sales and marketing expenses consist primarily of salaries, commissions to sales
personnel and agents, travel, tradeshow participation, public relations and
other promotional expenses. Sales and marketing expenses were $17.5 million,
$10.2 million and $7.0 million in 1998, 1997 and 1996, respectively,
representing an increase of 72.2% from 1997 to 1998 and 44.5% from 1996 to 1997.
Sales and marketing expenses accounted for 44.4%, 52.0% and 78.2% of total
revenues in 1998, 1997 and 1996, respectively. The increase in absolute dollars
was primarily the result of increased headcount to continue to build the direct
sales force along with additional marketing and promotional activities to
penetrate the market. The decline in sales and marketing expenses as a
percentage of total revenues is due to sales productivity improvements resulting
from the expansion of the Network Health product family, increased revenues from
existing customers and improved lead generation. Headcount in sales and
marketing at the end of 1998, 1997 and 1996 was 75, 44 and 37 people,
respectively.

GENERAL AND ADMINISTRATIVE EXPENSES

General and administrative expenses consist primarily of salaries for financial,
administrative and management personnel and related travel expenses, as well as
legal and accounting expenses. General and administrative expenses were $2.8
million, $2.1 million and $1.2 million in 1998, 1997 and 1996, respectively,
representing an increase of 36.0% from 1997 to 1998 and 74.9% from 1996 to 1997.
General and administrative expenses accounted for 7.1%, 10.5% and 13.0% of total
revenues in 1998, 1997 and 1996, respectively. The increase in absolute dollars
reflects personnel growth and associated costs in general support areas. General
and administrative expenses declined as a percentage of total revenues due to a
significant increase in revenues.

OTHER INCOME (EXPENSE), NET

Other income consists of interest earned on funds available for investment net
of interest paid in connection with the financing of capital equipment. The
Company realized net other income of $2.3 million, $297,000 and $45,000,
respectively, in 1998, 1997 and 1996.

LIQUIDITY AND CAPITAL RESOURCES

The Company has financed its operations, prior to its initial public offering,
primarily through the private sale of equity securities and a credit line for
equipment purchases. On October 24, 1997, the Company completed its initial
public offering of 3,335,000 shares of Common Stock at a price of $14.00 per
share. Of these shares, 2,735,000 were issued by the Company and 600,000 were
sold by selling shareholders. The Company received net proceeds of approximately
$34.7 million. The Company had working capital of $43.0 million at December 31,
1998.

Net cash provided by (used in) operating activities was $14.1 million, $2.0
million and $(2.9) million in 1998, 1997 and 1996, respectively. Cash, cash
equivalents and marketable securities were $50.4 million, $36.5 million and $1.7
million in 1998, 1997 and 1996, respectively. Deferred revenues increased for
the year ended December 31, 1998 by $3.0 million due to an increase in overall
sales activity; $2.8 million of this increase came from deferred maintenance
contracts and $216,000 was the result of service and software license sales with
remaining contingencies such as completion of services, product acceptance and
credit worthiness.

Investing activities have consisted of the acquisition of property and
equipment, most notably computer and networking equipment to support the growing
employee base and corporate infrastructure and also investments in marketable
securities. The Company manages its market risk on its investment securities by
selecting investment grade securities with the highest credit ratings of
relatively short duration that trade in highly liquid markets. Financing
activities consisted primarily of the issuance of common stock and exercise of
options during 1998 and 1997 and from the proceeds from and repayments of bank
borrowings in connection with equipment purchases during 1997 and 1996.

During 1996, the Company entered into an agreement for an equipment line of
credit in the amount of $1.0 million (the "Equipment Line") with Silicon Valley
Bank. The Equipment Line, as amended, bore interest at the bank's prime plus 2%
and was collateralized by substantially all of the Company's assets. In December
1997, the Company paid off all outstanding principal and interest due under this
agreement.


                                                                              17
<PAGE>   4
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS (CONTINUED)


The Company had a revolving working capital line of credit with Silicon Valley
Bank. Borrowings outstanding under the line were limited to the lesser of $2.5
million or 90% of eligible accounts receivable. The Company's line of credit
expired on April 2, 1998. The Company also entered into a new equipment line of
credit with Fleet National Bank during June of 1997 for up to $1.0 million. In
December, 1997, the Company paid off all outstanding principal and interest
under this agreement.

Pursuant to the Tax Reform Act of 1986, the utilization of net operating loss
carryforwards for tax purposes may be subject to an annual limitation if a
cumulative change of ownership of more than 50% occurs over a three-year period.
As a result of the Company's 1995 preferred stock financings, such a change in
ownership has occurred. As a result of this ownership change, the use of the net
operating loss carryforwards will be limited. The Company has determined that
its initial public offering did not cause another ownership change. The Company
has deferred tax assets of approximately $17.3 million comprised primarily of
net operating loss carryforwards and research and development credits. The
Company has fully reserved for these deferred tax assets by recording a
valuation allowance of $17.3 million, as the Company believes that it is more
likely than not that it will not be able to realize this asset.

Pursuant to paragraphs 20 to 25 of Statement of Financial Accounting Standards
(SFAS) No. 109, the Company considered both positive and negative evidence in
assessing the need for a valuation allowance at December 31, 1997 and 1998. The
factors that weighed most heavily on the Company's decision to record a full
valuation allowance were (i) the Company's history of losses, (ii) the
substantial restrictions on the use of its existing net operation loss (NOL)
carryforwards and (iii) the uncertainty of future profitability.

As a result of the ownership change described above, the future use of
approximately $16.6 million of the Company's NOL carryforwards are limited to
only $330,000 per year; the substantial majority of such NOL carryforwards will
expire before they can be used. Pursuant to the provisions of SFAS No. 109, the
Company used all of its remaining unrestricted NOL and credit carryforwards in
computing the 1998 tax provision. The Company is also subject to rapid
technology change, competition from substantially larger competitors, a limited
family of products and other related risks, as more thoroughly described in the
"Risk Factors" section of the Company's Form 10-K, for the fiscal year ended
December 31, 1998. The Company's limited operating success in late 1997 and 1998
and its dependence on a single product family in an emerging market makes the
prediction of future results difficult, if not impossible, especially in the
highly competitive software industry. As a result, the Company found the
evidence described above to be the most reliable objective evidence available in
determining that a full valuation allowance against its tax assets would be
necessary.

The Company's net operating loss deferred tax asset includes approximately $4.3
million pertaining to the benefit associated with the exercise and subsequent
disqualifying disposition of incentive stock options by the Company's employees.
When and if the Company realizes this asset, the resulting change in the
valuation allowance will be credited directly to additional paid-in capital,
pursuant to the provisions of SFAS No. 109.

The difference between the Company's 1998 effective tax rate of approximately
5.5% and the applicable statutory rate can be attributed to the use of the NOL
and credit carryforwards described above. In addition, the Company received a
tax benefit of approximately $500,000 pursuant to the exercise of employee stock
options. The Company recorded this benefit as a component of additional paid-in
capital.

The Company's current export sales are denominated in United States dollars. To
the extent that international sales continue to be denominated in United States
dollars, an increase in the value of the United States dollar relative to other
currencies could make the Company's products and services more expensive and,
therefore, potentially less competitive in international markets.

As of December 31, 1998, the Company's principal sources of liquidity included
cash and marketable securities. The Company believes that its current cash and
market securities and cash provided by future operations will be sufficient to
meet its working capital and anticipated capital expenditure requirements for
the next 12 months. Although operating activities may provide cash in certain
periods, to the extent the Company experiences growth in the future, its
operating and investing activities may require significant cash. Consequently,
any such future growth may require the Company to obtain additional equity or
debt financing.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS (CONTINUED)


YEAR 2000 COMPLIANCE / YEAR 2000 READINESS DISCLOSURE STATEMENT

The Company is aware of the issues associated with the programming code in
existing computer systems and software products as the millennium (Year 2000)
approaches. The Company has set up a task force which consists of the Director
of Information Technology (IT) and Operations, the Manager of System
Applications and representative personnel from each functional area. This task
force is addressing the Year 2000 issue in the following categories: the Network
Health product; internal business computer systems and software applications;
internal systems other than computer hardware and software; and systems of the
Company's external suppliers and service providers. The Company is also
assessing its Year 2000 associated costs, risks and potential contingency plans.
Despite the Company's efforts with respect to the Year 2000 issue, there can be
no assurance that the Company's business, results of operations or financial
condition would not be materially adversely affected by the failure of the
Company's products, its internal systems and applications or the systems of its
third-party suppliers and service providers to properly operate or manage data
beyond 1999.

NETWORK HEALTH PRODUCT

In 1997, the Company initiated the necessary development to ensure Year 2000
compliance in the Network Health family of applications and believes it has
achieved Year 2000 compliance in Network Health 4.1 which was released in August
1998. The Company's existing customers can receive this release, at no charge,
through their annual software maintenance contract. The Company requires its
customers to purchase software maintenance in order to receive product support.
Specifically, the Company defines Year 2000 Compliance as the following: no
value for current date will cause any interruption in operation; date-based
functionality must behave consistently for dates prior to, during and after Year
2000; in all interfaces and data storage, the century in any date must be
specified either explicitly or by unambiguous algorithms or inferencing rules;
Year 2000 must be recognized as a leap year. The Company's definition of Year
2000 Compliance is adopted from the British Standard Institute's Definition of
Year 2000 Conformity Requirements (PD2000-1). A copy of the standard is
available for review on the Company's website. The Company makes no guarantee
of, claims no responsibility for and disclaims any liability to its customers,
with respect to Year 2000 compliance of operating platforms, hardware, software
or other products not developed by the Company, including equipment monitored by
the Network Health product.

INTERNAL BUSINESS COMPUTER SYSTEMS AND SOFTWARE APPLICATIONS

In 1998, the Company commenced a Year 2000 date conversion project to address
all internal existing computer systems, software applications and related
computer equipment (e.g. printers) used in conjunction with its internal
operations. The Company plans to identify, modify, upgrade and/or replace any
systems that have been identified as non-Year 2000 compliant to minimize the
possibility of a material disruption to it business. The Company has finished
assessing all existing internal systems and expects to complete the compliance
process on these systems before the end of 1999.

INTERNAL SYSTEMS OTHER THAN COMPUTER HARDWARE AND SOFTWARE

The operation of office and facilities equipment such as fax machines,
photocopiers, telephone switches, security systems, elevators and other common
devices may also be affected by the Year 2000 issue. The Company has identified,
and is currently assessing its options to remediate, the Year 2000 issue on its
office and facilities equipment.

SYSTEMS OF EXTERNAL SUPPLIERS AND SERVICE PROVIDERS

The Company has initiated communications with third-party suppliers of the
computers, software and other equipment used, operated or maintained by the
Company to identify and, to the extent possible, to resolve any issues regarding
the Year 2000 issue. The Company has also initiated communications with
facilities service providers upon which the Company relies for daily operations.
All external suppliers and service providers have been asked to provide a
written assurance that they are also preparing to be Year 2000 compliant in a
timely manner, and that their products/services will be available to the Company
up to and beyond the Year 2000, without interruption. A response has been
received from approximately 50% of these suppliers and service providers.
However, there can be no assurance that the systems operated by other companies
upon which the Company relies will be Year 2000 compliant on a timely basis.


                                                                              19

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS (CONTINUED)


ASSOCIATED COSTS

To date, the Company has not incurred any material costs related to the
assessment of, and preliminary efforts to upgrade or replace existing systems
identified as non-Year 2000 compliant. Management is continuing to assess the
total Year 2000 compliance expense, but based on a preliminary review to date,
does not expect the amounts required to be expensed over the balance of 1999 to
have an adverse material effect on its business, results of operations or
financial condition. There can be no assurance, however, that further assessment
of the Company's internal systems and applications will not indicate that
additional Company efforts to assure Year 2000 compliance are necessary, and
that such efforts may be costly.

ASSOCIATED RISKS

The Company expects to identify and resolve all Year 2000 issues that could
materially adversely affect its business, results of operations or financial
condition. However, management realizes it may not be possible to determine with
complete certainty that all Year 2000 problems affecting the Company will be
identified or corrected in a timely manner. As a result, the Company could be at
risk of experiencing a significant number of operational inconveniences and
inefficiencies that may divert management's time and attention from its ordinary
business activities and at risk of experiencing a lesser number of serious
system or product failures that may require significant efforts by the Company
to prevent or alleviate material business disruptions.

CONTINGENCY PLANS

The Company recognizes the importance of readiness for potential worst case
scenarios. As a result, the Company is working to identify scenarios with
significant risks, which would require contingency plans. The Company expects to
develop and complete any needed contingency plans no later than the summer of
1999.
