                         Notes to Financial Statements
                          September 30, 1998 and 1997


1. BASIS OF PRESENTATION

The accompanying unaudited financial statements have been prepared in accordance
with the rules and regulations of the Securities and Exchange Commission for
interim financial statements, therefore, certain information and footnote
disclosures normally contained in annual financial statements have been
condensed or omitted.  These financial statements should be read in conjunction
with the audited financial statements included in the Company's Annual Report on
Form 10-K for the year ended December 31, 1997.

The accompanying unaudited financial statements of the Company reflect all
adjustments, consisting solely of adjustments of a normal recurring nature which
are, in the opinion of management, necessary to fairly present the financial
position as of September 30, 1998 and the results of operations and cash flows
for the interim periods presented.  The results for the interim periods ended
September 30, 1998 are not necessarily indicative of the results to be expected
for the entire year.

2. REVENUE RECOGNITION

The Company recognizes revenues from licenses of computer software provided that
a noncancelable license agreement has been signed, the software and related
documentation have been shipped, there are no material uncertainties regarding
customer acceptance, collection of the resulting receivable is deemed probable,
and no other significant vendor obligations exist.  Maintenance revenues are
deferred and recognized over the related contract period, generally three months
to five years.  Services and other revenues generated from professional
consulting and training services and software customization services are
recognized as the services are performed.  Hardware revenues are recognized upon
shipment.

Effective January 1, 1998, the Company adopted Statement of Position ("SOP") 
97-2 "Software Revenue Recognition," ("SOP 97-2") and SOP 98-4 "Deferral of the
Effective Date of a Provision of SOP 97-2, Software Revenue Recognition" ("SOP
98-4") which were issued October 27, 1997 and March 31, 1998, respectively, and
supersede SOP 91-1. These SOPs address revenue recognition from a conceptual
level and do not specifically address implementation guidance. These SOPs did
not have a material impact on the Company's results for the nine month period
ended September 30, 1998. The Company believes, based on its reading and
interpretation of these SOPs, that these statements may result in a deferral of
future revenue recognition, but the Company feels that any impact of this
statement will be reduced by its anticipated changes to its business practices.
These SOPs are complex issues that must be integrated into the Company's current
and future business practices. The final implementation of this statement may
differ from the Company's current interpretation with respect to the impact on
future earnings.

3.  INVENTORIES

Inventories consist of hardware and software purchased from third parties
pending shipment to customers and are recorded at the lower of cost or market.

4.  COMPUTATION OF EARNINGS (LOSS) PER SHARE (IN THOUSANDS EXCEPT PER SHARE
    DATA)

On December 31, 1997, the Company adopted SFAS No. 128, Earnings Per Share
("SFAS No. 128").  In accordance with SFAS No. 128, basic earnings per share is
computed using the weighted average number of common shares outstanding during
the period.  Diluted earnings per share is computed using the weighted average
number of common and dilutive common equivalent shares outstanding during the
period, using the treasury stock method for options.  The following is a
reconciliation of the denominator in the computation of diluted earnings per
share (the numerator equals the net income (loss)):

5.  RECENT ACCOUNTING PRONOUNCEMENTS

Effective January 1, 1998, the Company adopted SFAS No. 130, "Reporting
Comprehensive Income" ("SFAS 130").  During the periods presented, the Company
had no changes in equity from transactions or other events and circumstances
from non-owner sources.  Accordingly, a statement of comprehensive income has
not been provided as comprehensive income (loss) applicable to common
stockholders equals net income (loss) applicable to common stockholders for all
periods presented.

The FASB also recently issued SFAS No. 131, "Disclosure about Segments of an
Enterprise and Related Information" ("SFAS No. 131").  SFAS No. 131 establishes
standards for the way public business enterprises are to report information
about operating segments in annual financial statements and requires those
enterprises to report selected information about operating segments in interim
financial reports.  SFAS No. 131 is effective for the Company beginning in 1998.
The Company is in the process of evaluating its business segments as defined by
SFAS No. 131.

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which defines derivatives, requires that
all derivatives be carried at fair value, and provides for hedge accounting when
certain conditions are met.  SFAS No. 133 is effective for the Company in 2000.
Although the Company has not fully assessed the implications of SFAS No. 133,
the Company does not believe adoption of this statement will have a material
impact on the Company's financial position or results of operations.

6.  LONG-TERM OBLIGATIONS

Effective in the second quarter of 1998, the Company entered into a non-
cancelable license agreement to purchase new license technology which the
Company plans to incorporate into their suite of information management modules.
Payments under this agreement are due through December 2001, with a net present
value of $1,300,000 at September 30, 1998.  This amount will be amortized over
the expected life of four years, at the greater of straight line or the
percentage of units sold to date to total expected unit sales.  In addition, the
Company entered into a non-cancelable maintenance agreement with an annual
expense of $204,000 in 1998 and $326,000 each year thereafter through 2004
related to these purchased licenses.

                                       7
<PAGE>
 
The net present value of the license payments, discounted at 12.5%, have been
recorded as a long-term obligation. The remaining principal payments of
$1,341,000 are due as follows:  $121,000 in 1998, $595,000 in 1999, $323,000 in
2000, and $302,000 in 2001.

OVERVIEW

The Company provides information management software and solutions for
relationship-oriented financial institutions.  These solutions allow the
Company's customers to provide, among other things, financial services such as
checking, savings and investment accounts, home banking, credit and debit cards,
ATM access and consumer lending.  The Company's products are primarily targeted
at large and mid-sized credit unions who want to operate their system in-house.
For smaller credit unions, the Company works through value added resellers
("VARs") to provide the Company's products.  Combining the in-house
installations with services provided by the Company's VARs, the approximately
425 credit unions using the Company's software represent over 5.6 million
members and $30.0 billion in assets.

The Company derives its revenues primarily from software license fees, service
fees including items such as training and installation, custom development and
disaster recovery, and maintenance fees.  A significant portion of the Company's
revenues are derived from contracts with organizations that have long decision-
making cycles, typically from six to twelve months.  The decision to purchase
the Company's products is followed by an installation and training cycle which
is labor-intensive and generally requires at least four months to complete.
Each new customer system consists of the Company's ULTRAFIS product and selected
information management applications, services and hardware.

REVENUES
--------

The Company's revenues are comprised of software, customer maintenance, services
and other revenues and hardware revenues. Revenues from the Company's core
business, which excludes hardware, increased 26% from $6.0 million for the three
months ended September 30, 1997 to $7.6 million for the three months ended
September 30, 1998.  Revenues from the Company's core business increased 18%
from $17.5 million to $20.6 million for the nine month period ended September
30, 1997 and 1998, respectively.  Total revenues (including the direct sale of
hardware from which the Company is transitioning to focus on its core business)
for the three months ended September 30, 1998 increased 27% over the same period
in the prior year from $6.7 million to $8.6 million, respectively, and increased
7% from $22.0 million for the nine months ended September 30, 1997 to $23.4
million for the nine months ended September 30, 1998.

Software revenues increased 50% from $2.1 million for the three months ended
September 30, 1997 to $3.1 million for the three months ended September 30,
1998, and increased 63% from $5.2 million for the nine months ended September
30, 1997 to $8.5 million for the nine months ended September 30, 1998.  The
increase in software revenues is primarily attributable to the increase in sales
of the Company's information management modules to existing customers as well as
sales to new accounts.

The Company's maintenance revenues are derived from quarterly, annual, and
multi-year support agreements with its customers.  Maintenance revenues
increased by 10% from $2.5 million for the three months ended September 30, 1997
to $2.8 million for the three months ended September 30, 1998. Maintenance
revenues increased 9% from $7.6 million for the nine months ended September 30,
1997 to $8.3 million for the nine months ended September 30, 1998. The increase
for both periods was primarily a result of increased new information management
application modules installed during 1997 and the first nine months of 1998.

Services and other revenues increased by 21% from $1.4 million for the three
months ended September 30, 1997 to $1.7 million for the three months ended
September 30, 1998, and decreased 19% from $4.7 million for the nine months
ended September 30, 1997 to $3.8 million for the nine months ended September 30,
1998.  For the nine months ended September 30, 1998, the Company continued to
experience some customer requests to delay installations of products as these
customers focused on meeting Year 2000 preparation and testing requirements.
For the three month period ended September 30, 1998, the level of these delays
decreased as many of the Company's customers have satisfied their regulator-
mandated requirement to test all critical systems before year end. The revenue
decline for the nine month period ended September 30, 1998 was also attributable
to a decrease in training and installation activities due to lower new system
sales volumes during the first six months of 1998.  Additionally, service
revenues declined due to the transfer of the Company's direct service bureau

                                       10
<PAGE>
 
operations in the third quarter of 1997 to Premier Systems, Incorporated
("PSI"), the Company's largest service bureau VAR, for which the Company
recorded a gain of $0.6 million in the third quarter of 1997.

In the fourth quarter of 1997, the Company entered into a relationship with Ex-
Cel Solutions, Incorporated ("ESI") to configure, sell, distribute, and provide
service for the Company's HP and IBM hardware products and operating systems.
This decision was made to allow the Company to focus on its core businesses of
software, services, and maintenance.  Accordingly, hardware revenues decreased
from $4.4 million for the nine months ended September 30, 1997 to $2.8 million
for the nine months ended September 30, 1998.  The Company expects direct
hardware revenues in 1998 to continue to decline due to its newly formed
relationship with ESI.  This revenue decline, however, is expected to be
partially offset by service fees from ESI's sale of hardware to the Company's
customers.  For the three month ended September 30, 1998, hardware revenues
increased to $1.0 million from $0.7 million for the three month period ended
September 30, 1997.  This is primarily attributable to hardware sold during the
first six months of 1998 but not shipped until the third quarter ended September
30, 1998.

GROSS MARGIN
------------

Gross margin as a percentage of total revenue increased two percentage points
from 46% for the three months ended September 30, 1997 to 48% for the three
months ended September 30, 1998 and increased eight percentage points from 41%
for the nine months ended September 30, 1997 to 49% for the nine months ended
September 30, 1998 primarily due to increased sales of software and the
Company's transition of lower margin hardware sales to ESI.

Software gross margin as a percentage of software revenue decreased 11
percentage points from 83% for the three months ended September 30, 1997 to 72%
for the three months ended September 30, 1998.  This decline is attributable to
the release to customers in the third quarter of 1998 of products with
significant third party components.  These third party components have lower
margins than the Company's internally developed software.  While these products
are expected to continue to be a significant part of the Company's offerings, 
the Company anticipates that software gross margin in future periods will
normalize at a level somewhere between the results released in the second
quarter ending June 30, 1998 and the third quarter ending September 30, 1998.
Software gross margin increased one percentage point from 83% for the nine
months ended September 30, 1997 to 84% for the nine months ended September 30,
1998. The Company's software margins will continue to fluctuate depending on the
mix of sales of the Company's internally developed software versus software
purchased or licensed from a third party.

Gross margin percentage from maintenance revenues decreased by one percentage
point from 41% for the three months ended September 30, 1997 to 40% for the
three months ended September 30, 1998. Gross margin percentage from maintenance
decreased by one percentage point from 39% for the nine month period ended
September 30, 1997 to 38% for the nine month period ended September 30, 1998.
These slight decreases were primarily due to investments to improve customer
service and higher fees for third party maintenance costs.

Gross margin percentage from services and other revenues increased 27 percentage
points from 6% for the three months ended September 30, 1997 to 33% for the
three months ended September 30, 1998.  Services and other revenues increased 11
percentage points from 7% for the nine months ended September 30, 1997 to 18%
for the nine months ended September 30, 1998.  These increases are primarily
attributable to increased productivity in the service delivery area, price 
increases made for certain services, and service fees received from ESI's
sale of hardware to the Company's customers.

Hardware gross margin as a percentage of hardware revenues decreased eight
percentage points to 24% for the three month period ended September 30, 1998
from 32% for the three month period ended September 30, 1997.  For the nine
month period ended September 30, 1998, hardware margins decreased nine
percentage points compared to the same period in 1997.  These declines are
attributable to higher discounts for hardware as well as sales of an increased
proportion of lower margin third-party hardware.  As 

                                       11
<PAGE>
 
previously discussed, the Company has entered into a relationship under which
ESI will sell and configure hardware in order to allow the Company to focus on
its core businesses. The Company expects direct hardware revenue in 1998 to
continue to decline, and does not expect to have any appreciable sales or margin
from hardware by the end of 1998. This revenue decline, however, is expected to
be partially offset by service fees received from ESI's sale of hardware to the
Company's customers.

OPERATING EXPENSES
------------------

Product development expenses increased from $1.1 million for the three months
ended September 30, 1997 to $1.2 million for the three months ended September
30, 1998.  The increase in total dollar spending was primarily the result of
additional costs for new information management module development.   Product
development as a percent of total revenues decreased from 16% for the three
months ended September 30, 1997 to 14% for the three months ended September 30,
1998 and decreased slightly from 16% to 15% of total revenues for the nine month
period ended September 30, 1997 and 1998, respectively.

Selling, general and administrative expenses increased from $2.3 million for the
three months ended September 30, 1997 to $2.5 million for the three months ended
September 30, 1998.  This increase is primarily attributable to increases in
administrative expenses. Selling, general and administrative expenses decreased
from $9.4 million for the nine months ended September 30, 1997 to $7.3 million
for the nine months ended September 30, 1998.  This decrease is primarily
attributable to reductions in staffing levels at the end of the first quarter in
1997. 

CERTAIN FACTORS AFFECTING FUTURE OPERATING RESULTS

MARKET CONDITIONS
-----------------

The Company's future operating results will depend upon conditions in its market
that may affect demand for its products and its ability to enhance its existing
products and introduce new products that meet market demands on a timely basis.
The Company must also manage growth and change effectively as failure to do so
could materially and adversely affect its business and operating results.

INSTALLATION ISSUES
-------------------

Installation of the Company's ULTRAFIS system is a complex process that must
typically be done without any disruption of the customer's service.  Failure by
the Company to successfully install an ULTRAFIS system could result in
significant loss of revenue in a particular quarter and fluctuation in the
Company's results of operations.  Although the Company schedules the
installations of its products several months in advance, its ability to achieve
its revenue plans, both in the near term and in the long term, depends on the
Company's continued ability to sign new customer contracts and to complete such
contracts on schedule.  Failure to close new customer contracts as a result of
lost sales or deferrals of customer decisions could have a material adverse
impact on the future operating results.  There can be no assurance that sales or
installations will continue to occur at historical rates or in accordance with
the Company's expectations.  Because the Company's operating expenses are based
on anticipated revenue levels and a high percentage of the Company's expenses
are relatively fixed, a small variation in the timing of the recognition of
specific revenues could cause significant variations in operating results from
quarter to quarter.

CUSTOMER ACCEPTANCE
-------------------

The Company's quarterly and annual revenues and operating results have varied
significantly in the past, and may continue to do so in the future.  Operating
results may fluctuate due to factors such as the demand for the Company's
products, the introduction and acceptance of new products and product
enhancements by the Company or its competitors, changes in the levels of
operating expenses, customer order deferrals in anticipation of new products,
competitive conditions in the credit union and financial services markets and
economic conditions generally or in various industry segments.  In addition, a
significant portion of the 

                                       12

Company's business has been derived from substantial contracts with large
organizations with long decision-making cycles, and the timing of such orders
has caused material fluctuations in the Company's operating results. The
Company's expense levels are based in part on its expectations regarding future
revenues and in the short term are fixed to a large extent. Therefore, the
Company may be unable to adjust spending in a timely manner to compensate for
any unexpected revenue shortfall. As a result, if anticipated revenues do not
occur or are delayed, the Company's operating results would be
disproportionately affected. The Company expects quarterly and annual
fluctuations to continue for the foreseeable future. Accordingly, the Company
believes that period-to-period comparisons of its financial results should not
be relied upon as an indication of future performance.

LEGISLATIVE ACTIVITY
--------------------

On February 25, 1998, the United States Supreme Court affirmed a ruling by a
United States District Court providing that federal credit unions may not extend
membership benefits to individuals who are not part of the credit union's
original charter group.  This ruling imposes limits on new customers that a
federal credit union may attract.  As a result, some federal credit unions have
expressed a reluctance to pursue extensive capital purchases until the impact of
the ruling is further assessed.  While federal credit unions represent
approximately 60% of all credit unions, less than half of these credit unions
are affected by this ruling.  The interpretation of this ruling could have a
material adverse effect upon the Company's business, financial conditions, and
results of operations. Since this Supreme Court ruling, there has been
significant congressional legislative activity.  On August 7, 1998, President
Clinton signed into law the Credit Union Membership Access Act ("CUMAA").  The
CUMAA allows multiple Select Employee Groups to have membership in the
same credit union.  While the CUMAA is effective immediately, certain provisions
of the CUMAA require the enactment of rules and regulations prior to
implementation.  The Company is currently assessing the impact that the CUMAA
may have on its operations and continues to monitor all legislative activity
that may affect its operations.

YEAR 2000
---------

Many software computer programs in the industry rely on internal date formats
using two-digit data programs to perform computation and decision-making
functions that may cause computer systems generally to malfunction with respect
to dates beginning with the Year 2000. The Company's products use an internal
date format that has never relied on two-digit data programs and which was
upgraded and made available to the Company's customers in August, 1994.  The
Company believes that date entry will not be a material issue either with 
Company's information management software products or the Company's own 
information management applications. 

The costs for Year 2000 compliance have been immaterial. The Company estimates
that such costs the Company has incurred through September 30, 1998 have been
substantially less than $100,000. Such costs have primarily resulted from the
Company's investment of staff time understanding Year 2000 compliance issues as
well as understanding obligations of the Company's customers to undergo
extensive Year 2000 compliance testing of their critical systems.

The Company has conducted its own Year 2000 compliance testing of its currently 
marketed products and has found no significant Year 2000 related issues.

In addition, on April 15, 1998, the Information Technology Association of 
America ("ITAA") announced that the Company had achieved Year 2000 
certification. ITAA is a trade association dealing with Year 2000 software 
compliance in the information technology industry. ITAA * 2000 is the ITAA's 
century date change certification program. The ITAA * 2000 Certification Program
provides information technology companies with the opportunity to have a neutral
and objective third-party evaluation of their Year 2000 processes and methods.

The Company has not evaluated its customers' Year 2000 compliance status. The
Company's customers are, however, required by the National Credit Union
Association ("NCUA") to test their critical systems for Year 2000 compliance
prior to December 31, 1998. Due to this extensive testing process, the Company's
products have been undergoing Year 2000 compliance testing since June, 1998 at
many customer sites. To date, no significant issues have been reported.

The Company has evaluated Year 2000 compliance issues with the third party
products the Company currently markets. While the Company has identified no 
significant Year 2000 related issues with such products, the Company is in the 
process of obtaining written verification of Year 2000 compliance from the 
vendors of such products.

The Company has considered obtaining Year 2000 compliance insurance as well as 
developing various contingency plans. Given that both internal and customer 
testing has indicated the Company's current products are Year 2000 compliant, 
the Company has concluded that neither Year 2000 compliance insurance nor 
contingency plans are necessary. For these same reasons, the Company has also 
concluded that any future Year 2000 compliance costs, if any, will not be 
material. 

The Company is currently not aware of any significant Year 2000 issues with its
major internal systems.

The Company expects no material impact to its financial position as a result of 
any pending Year 2000 issues related to its products.

LIQUIDITY AND CAPITAL RESOURCES

The Company's management believes current cash, cash equivalents and short-term
investments and expected cash generated from operations will satisfy its
expected working capital and capital expenditure requirements for the
foreseeable future.

The Company has a factoring agreement and a capital equipment facility.  The
factoring agreement provides for a 0.5% administrative fee for each receivable
purchased and a 1.75% monthly finance charge for as long as each purchased
receivable remains outstanding.  The factoring agreement renews, unless
terminated by the Company or the bank, in April 1999.  As of September 30, 1998,
the Company has not utilized the factoring agreement.  As of September 30, 1998,
the outstanding balance on the capital equipment facility was $393,000.  The
capital equipment facility bears interest at prime plus 0.25%. No further draws
are available and the Company established cash collateral for the capital
equipment facility balance.  The Company is paying off this balance and reducing
the cash collateral in monthly installments of $17,000. Borrowings under the
factoring agreement and capital equipment facility are secured by all tangible
and intangible assets of the Company.

Capital expenditures of $0.5 million during the first nine months of 1998 were
primarily for computer and miscellaneous equipment.

Net cash provided by operations was $0.8 million for the nine months ended
September 30, 1998, including a $631,000 net income for the nine months ended
September 30, 1998.  For the nine months ended September 30, 1997, net cash
provided by operations was $0.1 million.  Unbilled revenues increased $1.9
million from $2.3 million to $4.2 million.  This increase can be attributed to
the large number of information management module orders signed late in the
third quarter that have yet to be installed.  Inventories increased $1.4 million
from September 1997 to September 1998 due primarily to the purchase of third
party software licenses as discussed below. The increase of $1.7 million in 
long-term obligations is also related to the purchase of these software
licenses.

Effective in the second quarter of 1998, the Company entered into a non-
cancelable license agreement to purchase new license technology which the
Company plans to incorporate into their suite of information management modules.
Payments under this agreement are due through December 2001, with a net present
value of $1,300,000.  This amount will be amortized over the expected life of
four years, at the greater of straight line or the percentage of units sold to
date to total expected unit sales.  In addition, the Company entered into a non-
cancelable maintenance agreement with an annual expense of $204,000 in 1998 and
$326,000 each year thereafter through 2004 related to these purchased licenses.
