                      TRANSACTION SYSTEMS ARCHITECTS, INC.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


1.   Consolidated Financial Statements

     Transaction Systems Architects, Inc. (the "Company" or "TSA"), a Delaware
corporation, develops, markets, installs and supports a broad line of software
products and services primarily focused on facilitating electronic payments and
electronic commerce. In addition to its own products, the Company distributes,
or acts as a sales agent for, software developed by third parties. The products
are used principally by financial institutions, retailers and e-payment
processors, both in domestic and international markets.

     The condensed consolidated financial statements include the accounts of the
Company and its wholly-owned subsidiaries. All significant intercompany balances
and transactions have been eliminated. The preparation of the consolidated
financial statements in conformity with accounting principles generally accepted
in the United States requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the consolidated financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

     The condensed consolidated financial statements at December 31, 2001, and
for the three months ended December 31, 2001 and 2000, are unaudited and reflect
all adjustments (consisting only of normal recurring adjustments) which are, in
the opinion of management, necessary for a fair presentation of the financial
position and operating results for the interim periods. The condensed
consolidated financial statements should be read in conjunction with the
consolidated financial statements and notes thereto, together with management's
discussion and analysis of financial condition and results of operations,
contained in the Company's Annual Report on Form 10-K for the fiscal year ended
September 30, 2001. The results of operations for the three months ended
December 31, 2001 are not necessarily indicative of the results that may be
achieved for the entire fiscal year ending September 30, 2002.

2.   Revenue Recognition

     The Company generates revenues from licensing software and providing
postcontract customer support (maintenance or "PCS") and other professional
services. The Company uses written contracts to document the elements and
obligations of arrangements with its customers. Arrangements that include the
licensing of software typically include PCS and, at times, include other
professional services. PCS includes the right to unspecified upgrades on a
when-and-if-available basis and ongoing technical support. The other
professional services may include training, installation or consulting. The
Company also performs professional services for customers under arrangements
that do not include the licensing of software.

     Revenues under multiple-element arrangements, which may include several
software products or professional services sold together, are allocated to each
element based upon the residual method in accordance with American Institute of
Certified Public Accountants Statement of Position ("SOP") 98-9, "Software
Revenue Recognition, With Respect to Certain Arrangements." Under the residual
method, the fair value of the undelivered elements is deferred and subsequently
recognized. The Company has established sufficient vendor specific objective
evidence of fair value for PCS and other professional services based upon the
price charged when these elements are sold separately. Accordingly, software
license fee revenues are recognized under the residual method in arrangements in
which the software is licensed with PCS and/or other professional services, and
the undelivered elements of the arrangement are not essential to the
functionality of the delivered software.

     The Company recognizes software license fees upon execution of the signed
contract, delivery of the software to the customer, determination that the
software license fees are fixed or determinable, and determination that the
collection of the software license fees is probable. The software license is
typically for a term of up to 60 months and does not include a right of return.
The term for the PCS element of a software arrangement is typically for a period
shorter than the term of the software license, and can be renewed by the
customer over the remaining term of the software license. PCS or maintenance
revenues are recognized ratably over the term of the arrangement on a
straight-line basis. The other professional services element of a software
arrangement is typically accounted for separately as the services are performed
for time-and-materials contracts or on a percentage-of-completion basis for
fixed-price contracts. In those instances where the services are essential to
the functionality of any other element of the arrangement, contract accounting
is applied to both the software and services elements of the arrangement.

     The Company follows two methods for pricing its software licenses. Under
the first method, the software license is priced based upon the number of
transactions processed by the customer ("transaction-based pricing"). Under
transaction-based pricing, the customer is allowed to process a contractually
predetermined maximum volume of transactions per month for a specified period of
time. Once the customer's transaction volume exceeds this maximum volume level,
the customer is required to pay additional license fees for each incremental
volume level. Under the second method, the software license is priced on a per
copy basis and tiered to recognize different performance levels of the
customer's processing hardware ("designated-equipment-group pricing"). Under
designated-equipment-group pricing, the customer pays a license fee for each
copy of the software for a specified period of time.

     Licensees are typically given two payment options. Under the first payment
option, the licensee can pay a combination of an Initial License Fee ("ILF"),
where the licensee pays a portion of the total software license fees at the
beginning of the software license term, and a Monthly License Fee ("MLF"), where
the licensee pays the remaining portion of the software license fees over the
software license term. In certain arrangements, the customer is contractually
committed to making MLF payments for a minimum number of months. If the customer
decides to terminate the arrangement prior to paying the minimum MLF payments,
the remaining minimum MLF payments become due and payable. Under the second
payment option, the Company offers a Paid-Up-Front ("PUF") payment option,
whereby the total software license fees are due at the beginning of the software
license term. Under either payment option, the Company is not obligated to
refund any payments received from the customer. In the combination ILF and MLF
payment option, the Company recognizes the ILF portion of the software license
fees upon delivery of the software, assuming all other revenue recognition
criteria were met. In the PUF payment option, the Company recognizes the total
software license fees upon delivery of the software, assuming all other revenue
recognition criteria were met.

     In addition to SOP 98-9, the Company accounts for its software arrangements
in accordance with SOP 97-2, "Software Revenue Recognition." The primary
software revenue recognition criteria outlined in SOP 97-2 include: evidence of
an arrangement; delivery; fixed or determinable fees; and collectibility. SOP
97-2 specifies that extended payment terms in a software licensing arrangement
may indicate that the software license fees are not deemed to be fixed or
determinable. In addition, if payment of a significant portion of the software
license fees is not due until more than twelve months after delivery, the
software license fees should be presumed not to be fixed or determinable, and
thus should be recognized as the payments become due. However, SOP 97-2
specifies that if a company has a standard business practice of using extended
payment terms in software licensing arrangements and has a history of
successfully collecting the software license fees under the original terms of
the software licensing arrangement without making concessions, the company can
overcome the presumption that the software license fees are not fixed or
determinable. If the presumption is overcome, the company should recognize the
software license fees when all other SOP 97-2 revenue recognition criteria are
met.

     The Company has concluded that for certain BASE24 and ICE software
arrangements where the customer is contractually committed to make MLF payments
that extend beyond twelve months, the "fixed or determinable" presumption has
been overcome and software license fee revenues should be recognized upon
meeting the other SOP 97-2 revenue recognition criteria. In making this
determination, the Company considered the characteristics of the software
product, the customer purchasing the software, the similarity of the economics
of the software arrangements with previous software arrangements and the actual
history of successfully collecting under the original terms without providing
concessions. The software license fees recognized under these arrangements are
referred to as "Recognized-Up-Front MLFs." For all other products, it has been
concluded that (1) the Company does not have a standard business practice of
using extended payment terms, and/or (2) the Company does not have a long-range
history of successful collections for those products.

     The present value of Recognized-Up-Front MLFs, net of third-party
royalties, recognized during the three months ended December 31, 2001 and 2000
totaled approximately $4.0 million and $9.1 million, respectively. The discount
rates used to determine the present value of these software license fees,
representing the Company's incremental borrowing rates, ranged from 9.00% to
9.25% during the three months ended December 31, 2001, and from 9.50% to 11.00%
during the three months ended December 31, 2000. Recognized-Up-Front MLFs that
have been recognized as software license fee revenues by the Company, but not
yet billed, are reflected in accrued receivables in the accompanying condensed
consolidated balance sheets.

3.   Line of Credit Facilities

     The Company has a $25.0 million bank line of credit agreement with a large
United States bank secured by certain trade receivables. This credit agreement
provides that the Company must satisfy certain specified earnings, working
capital and minimum tangible net worth requirements, as defined, and places
restrictions on the Company's ability to, among other things, sell assets, incur
debt, pay dividends, participate in mergers and make investments or guarantees.
The Company also has a line of credit agreement with a large foreign bank in the
amount of 3.0 million British Sterling, which translates to approximately $4.4
million as of December 31, 2001. The foreign credit agreement requires the
Company to maintain minimum tangible net worth within the Company's wholly-owned
subsidiary, ACI Worldwide (EMEA) Ltd. The U.S. credit facility expires in June
2002 and the foreign credit facility expires in October 2002.

     Interest on the U.S. credit facility accrues at an annual rate equal to
either the bank's prime rate less .25% or the LIBOR rate plus 1.75% and is
payable monthly. Interest on the foreign credit facility accrues at an annual
rate of 1% above the bank's "base rate." During the three months ended December
31, 2001 and 2000, the Company recorded interest expense of $128,000 and
$481,000, respectively, related to its line of credit facilities. The carrying
amounts of the Company's credit facilities approximate fair value due to their
variable interest rates. Current U.S. line of credit borrowings outstanding
totaled $5.0 million as of December 31, 2001, with an interest rate on these
borrowings of 4.50%. The remaining $24.4 million is available to the Company for
future borrowings. The Company is in compliance with all debt covenants as of
December 31, 2001.

4.   Non-Cash and Other Charges

     The Company continually evaluates its investment holdings and long-lived
assets for evidence of impairment. During the three months ended December 31,
2001 and 2000, after considering current market conditions for technology
companies and specific information regarding those companies in which the
Company has an ownership interest, the Company determined that the declines in
market value for certain of its investment holdings were "other than temporary"
and charges to earnings for the declines in market value were required.
Therefore, the Company recorded non-cash charges of $2.9 million and $12.4
million, respectively, during the three months ended December 31, 2001 and 2000.
In addition, the Company expensed costs of $1.9 million associated with the
cancelled initial public offering of its wholly-owned subsidiary, Insession
Technologies, Inc. in the three months ended December 31, 2000.

     During the third quarter of fiscal 2001, the Company closed or
significantly reduced the size of certain product development organizations
and geographic sales offices. The Company also made executive management
changes and transferred its 70% ownership in Hospital Health Plan Corporation
to the minority shareholder. These actions resulted in a charge of $22.0 million
during the third quarter of fiscal 2001.

     Charges associated with these actions related to asset impairments, lease
obligations, termination benefits and other restructuring charges. Asset
impairments related to the write-off of property and equipment in vacated
office facilities and other-than-temporary declines in the fair value of
certain notes receivables. Lease obligations related to vacated corporate
office facilities. Amounts expensed represent estimates of undiscounted future
cash outflows, offset by anticipated third-party purchases or sub-leases.
Termination benefits were comprised of severance-related payments for all
employees terminated in connection with the operational restructuring and the
partial forgiveness of a note receivable from an executive officer.
Termination benefits do not include any amounts for employment-related
services prior to termination. Other restructuring charges included settlement
costs and allowance provisions for customers under related contractual
obligations.

     At September 30, 2001, the remaining accrued liability associated with
the restructuring and other charges described above was $4.0 million and
consisted of $1.4 million in lease obligations, $1.5 million in termination
benefits and $1.1 million in other restructuring charges. During the first
quarter of fiscal 2002, the Company reduced the liability related to these
items by approximately $100,000. The Company expects approximately $3.1
million of the remaining $3.9 million liability to be paid during the
remainder of fiscal 2002. The remaining portion, consisting primarily of lease
obligations, will be paid during fiscal 2003.

5.   Goodwill and Other Intangible Assets

     In June 2001, the Financial Accounting Standards Board (the "FASB")
released Statement of Financial Accounting Standards ("SFAS") No. 142, "Goodwill
and Other Intangible Assets," which established new accounting and reporting
requirements for goodwill and other intangible assets (with indefinite lives)
acquired in business combinations. Upon adoption of SFAS No. 142, goodwill and
other intangible assets with indefinite lives will continue to be recognized as
assets, but will not be amortized as previously required by Accounting
Principles Board Opinion No. 17, "Intangible Assets."

     SFAS No. 142 requires that goodwill be tested for impairment at the
reporting unit level at the time of adoption and at least annually thereafter,
utilizing a two-step methodology. The initial step requires the Company to
determine the fair value of each reporting unit and compare it to the carrying
value, including goodwill, of such unit. If the fair value exceeds the carrying
value, no impairment loss would be recognized. However, if the carrying value of
the reporting unit exceeds its fair value, the goodwill of this unit may be
impaired. The amount of impairment, if any, would then be measured in the second
step.

     Effective October 1, 2001, the Company adopted SFAS No. 142 and hired an
independent consultant to perform valuations of the Company's reporting units
that contain goodwill. Completion of the initial step of testing indicated that
the carrying value of one reporting unit exceeded its estimated fair value. Fair
value was determined using a discounted cash flow methodology. Thereafter, given
the indication of a potential impairment, the independent consultant completed
step two of the test. Based on that analysis, an impairment loss of $25.7
million (net of income tax benefit of $6.2 million), or $0.73 per basic and
diluted share, was recognized as a cumulative effect of accounting change. The
impairment within this reporting unit resulted primarily from overall softness
in discretionary information technology spending and slower than expected
adoption of secure document delivery technology.

6.   Common Stock and Earnings Per Share

     Exchangeable shares and options received by shareholders of MessagingDirect
Ltd. ("MDL") that have not yet been converted into TSA Class A Common Stock are
included in Class A Common Stock for presentation purposes on the September 30,
2001 and December 31, 2001 condensed consolidated balance sheets, and are
included in common shares outstanding for earnings per share ("EPS")
computations for the three months ended December 31, 2001. Exchangeable shares
and MDL options included in Class A Common Stock totaled 636,243 shares and
18,992 options as of December 31, 2001, and 650,146 shares and 20,040 options as
of September 30, 2001.

     EPS has been computed in accordance with SFAS No. 128, "Earnings Per
Share." Basic EPS is calculated by dividing net income available to common
stockholders (the numerator) by the weighted average number of common shares
outstanding during the period (the denominator). Diluted EPS is computed by
dividing net income available to common stockholders, adjusted for the effect of
any outstanding dilutive securities (the numerator), by the weighted average
number of common shares outstanding, adjusted for the dilutive effect of
outstanding dilutive securities (the denominator). For the three months ended
December 31, 2001 and 2000, basic and diluted EPS are the same, as any
outstanding dilutive securities were antidilutive due to the net loss in both
periods.

     The Company's products and services are currently organized within three
business units: (1) ACI Worldwide, (2) Insession Technologies and (3) IntraNet,

primarily by financial institutions, retailers and e-payment processors. Its
products are used to route and process transactions for automated teller machine
networks; process transactions from traditional point of sale devices, wireless
devices and the Internet; handle PC and phone banking transactions; control
fraud and money laundering; process electronic benefit transfer transactions;
authorize checks; establish frequent shopper programs; automate settlement, card
management and claims processing; and issue and manage multi-functional
applications on smart cards. MDL activities are included in the ACI Worldwide
business unit. Insession Technologies products facilitate communication, data
movement, monitoring of systems and business process automation across computing
systems, involving mainframes, distributed computing networks and the Internet.
IntraNet, Inc. products offer high-value payments processing, bulk/recurring
payments processing, wire room processing, global messaging, integration
payments management and continuous link settlement processing.

          Results of Operations.

Overview

     Transaction Systems Architects, Inc. ("TSA" or the "Company") develops,
markets, installs and supports a broad line of software products and services
primarily focused on facilitating electronic payments and electronic commerce.
In addition to its own products, the Company distributes, or acts as a sales
agent for, software developed by third parties. The products and services are
used principally by financial institutions, retailers and e-payment processors,
both in domestic and international markets.

Business Segments

     The Company's products and services are currently organized within three
business units: (1) ACI Worldwide, (2) Insession Technologies and (3) IntraNet,
Inc. Most of the Company's products and services are marketed and supported

Europe/Middle East/Africa ("EMEA") and Asia/Pacific. Each distribution network
has its own sales force and supplements this with reseller and/or distributor
networks.

units for the three months ended December 31, 2001 and 2000 (in thousands):

Backlog

     The Company defines recurring revenue backlog to be all monthly license
fees, maintenance fees and facilities management fees specified in executed
contracts to the extent that the Company contemplates recognition of the related
revenue within one year. The Company includes in its non-recurring revenue
backlog all fees (other than recurring) specified in executed contracts to the
extent that the Company contemplates recognition of the related revenue within
one year.

     The following table sets forth the Company's recurring and non-recurring
revenue backlog, by business unit, as of December 31, 2001 and 2000 (in

     Revenues. Total revenues for the first quarter of fiscal 2002 decreased
$9.3 million, or 12.5%, from the comparable period in fiscal 2001. The decrease
is the result of a $8.1 million, or 19.2%, decrease in software license fees
revenue and a decrease of $4.7 million, or 29.0%, decrease in services revenue
offset by a $3.5 million, or 22.0%, increase in maintenance fees revenue.

    The decrease in software license fee revenues for the first quarter fiscal
2002 is primarily the result of a decreased demand for the Company's ACI
Worldwide products, offset by a slight increase in demand for Insession
Technologies' and IntraNet, Inc.'s products. The decrease in demand for ACI
Worldwide's products is due to fewer transaction volume upgrades received during
the first quarter of fiscal 2002 as compared to the first quarter of fiscal
2001. This decrease is due to current global economic conditions that have
caused many of the Company's customers to forecast a slowing of electronic
transaction volume growth. As a result, these customers have reduced their
information technology budgets and spending commitments. For ACI Worldwide, the
first quarter of fiscal 2001 included a $6.2 million transaction volume upgrade
that resulted from a merger of two banks in the EMEA region. Revenue from the
first quarter of fiscal 2002 does not include any transactions of this size.

    In fiscal 2001, the Company changed its sales compensation plans for its ACI
Worldwide and Insession Technologies sales forces to emphasize PUF contracts for
both customer renewals and new customers rather than emphasizing ILF/MLF
contracts. Over time, the impact of this change is to increase the amount of PUF
revenue and reduce the amount of MLF revenue.

    The increase in maintenance fee revenues is due to the growth in the
installed base of the Company's software products in all three of its business
units.

    The decrease in services revenue for the first quarter of fiscal 2002
resulted from lower demand for technical and project management services, which
was primarily caused by decreased sales of the Company's ACI Worldwide products.
Offsetting this decrease was an increase is services revenues in the Company's
IntraNet, Inc. business unit related to services performed while migrating
customers to its new RS6000-based wire transfer product.

     Expenses. Total operating expenses for the first quarter of fiscal 2002
decreased $10.1 million, or 13.3%, as compared to the first quarter of fiscal
2001 (excluding $2.4 million of goodwill amortization charges in the first
quarter of fiscal 2001). During the third quarter of fiscal 2001, the Company
implemented a restructuring plan whereby it closed or significantly reduced the
size of certain product development organizations and geographic sales offices,
made executive management changes and transferred ownership in HHPC to the
minority shareholder. These actions have caused the Company's overall operating
expenses to decline.

     Cost of software license fees for the first quarter of fiscal 2002
decreased $0.6 million, or 5.1%, as compared to the first quarter of fiscal
2001. This decrease was due primarily to a decrease in royalties owed to the
owners of third-party products resulting from decreases in third-party product
sales volumes and a decrease in the royalty rate for one third-party product.

     Cost of maintenance and services for the first quarter of fiscal 2002
decreased $2.9 million, or 15.7%, as compared to the first quarter of fiscal
2001. This decrease was the result of fewer staff needed to support the
Company's services-related business.

     Research and development ("R&D") costs for the first quarter of fiscal 2002
decreased $1.0 million, or 10.1%, as compared to the first quarter of fiscal
2001. The Company terminated further development of certain products as part of
the fiscal 2001 corporate restructuring, causing this decrease. R&D costs as a
percentage of total revenues for the first quarter of fiscal 2002 were 13.9% as
compared to 13.5% for the first quarter of fiscal 2001. The Company capitalizes
costs related to certain internally-developed software when the resulting
products reach technological feasibility. Software development costs capitalized
in the first three months of fiscal 2002 and 2001 totaled approximately $0.3
million and $1.5 million, respectively.

     Selling and marketing costs for the first quarter of fiscal 2002 decreased
$3.1 million, or 15.6%, as compared to the first quarter of fiscal 2001. Selling
and marketing costs as a percentage of total revenues for the first quarter of
fiscal 2002 were 25.5% as compared to 26.4% for the first quarter of fiscal
2001. The decrease for the first quarter of fiscal 2002 is due to a decrease in
variable sales compensation expense resulting from less than expected sales and
profitability, as well as reduced costs resulting from the fiscal 2001 corporate
restructuring.

     General and administrative costs for the first quarter of fiscal 2002
decreased $2.5 million, or 15.4%, as compared to the first quarter of fiscal
2001. The decrease for the first quarter of fiscal 2002 as compared to the same
period in fiscal 2001 is attributable to reductions in personnel and occupancy
costs resulting from the fiscal 2001 corporate restructuring, as well as a
decrease in bad debts expense.

     Other Income and Expenses. The increase in net interest income in fiscal
2002 is primarily due to a decrease in borrowings on the Company's line of
credit facilities, resulting in decreased interest expense, as well as an
increase in interest income which resulted from an increase in the Company's
cash balance.

     The Company continually evaluates its investment holdings for evidence of
impairment. After considering current market conditions for technology companies
and specific information regarding those companies in which the Company has an
ownership interest, the Company determined that the declines in market value for
certain of its investment holdings were "other than temporary" and charges to
earnings for the declines in market value were required. Therefore, the Company
recorded non-cash charges of $2.9 million and $12.4 million during the three
months ended December 31, 2001 and 2000, respectively. In addition, the Company
expensed costs of $1.9 million associated with the cancelled initial public
offering of its wholly-owned subsidiary, Insession Technologies, Inc. in the
three months ended December 31, 2000. Also included in other expenses are
foreign currency translation gains and losses recognized by the Company.

     Income Taxes. The effective tax rate for the first quarter of fiscal 2002
was approximately 20% as compared to 19% for the first quarter of fiscal 2001.
The Company adopted SFAS No. 142 (see Footnote 5 for further details) as of
October 1, 2001. As a result of adopting SFAS No. 142, the Company recognized an
impairment loss on the carrying value of recorded goodwill and realized an
income tax benefit resulting from this impairment loss. The effective tax rate
for the first quarter of fiscal 2002 is lower than would be expected as the
Company recorded a valuation reserve against a portion of this tax benefit.

     As of December 31, 2001, the Company has deferred tax assets of $58.4
million and deferred tax liabilities of $2.0 million. Each quarter, the Company
evaluates its historical operating results as well as its projections for the
future to determine the realizability of the deferred tax assets. This analysis
resulted in a valuation allowance of $26.4 million being recorded as of December
31, 2001. The Company intends to analyze the realizability of the net deferred
tax assets at each future reporting period. Such analysis may indicate that the
realization of various deferred tax benefits has changed and, therefore, the
valuation reserve may be adjusted accordingly.

Liquidity and Capital Resources

     As of December 31, 2001, the Company's principal sources of liquidity
consisted of $36.8 million in cash and cash equivalents, and available bank
lines of credit. The Company has a $25.0 million bank line of credit agreement
with a large United States bank secured by certain trade receivables of TSA.
This credit agreement provides that the Company must satisfy certain specified
earnings, working capital and minimum tangible net worth requirements, as
defined, and places restrictions on the Company's ability to, among other
things, sell assets, incur debt, pay dividends, participate in mergers and make
investments or guarantees. The Company also has a line of credit agreement with
a large foreign bank in the amount of 3.0 million British Sterling, which
translates to approximately $4.4 million as of December 31, 2001. The foreign
credit agreement requires the Company to maintain minimum tangible net worth
within the Company's wholly-owned subsidiary, ACI Worldwide (EMEA) Ltd. Line of
credit borrowings outstanding totaled $5.0 million as of December 31, 2001. The
remaining $24.4 million is available to the Company for future borrowings. The
Company is in compliance with all debt covenants as of December 31, 2001.

     The Company's net cash flows provided by operating activities for the first
quarter of fiscal 2002 amounted to $14.2 million. Net cash used in operating
activities during the first quarter of fiscal 2001 was $9.0 million. In an
effort to enhance upfront software license fee payments, the Company adopted an
initiative in fiscal 2001 to pursue PUF payment options for its software
licensing rather than ILF/MLF payment options. Under the PUF payment option, the
licensee pays the license fee at the beginning of the software term whereas
under the ILF/MLF payment option, the licensee pays a portion of the software
license fees at the beginning of the software term and the remaining portion
over the software license term. The improvement in operating cash flows in the
first quarter of fiscal 2002 as compared to the first quarter of fiscal 2001 was
primarily due to a decrease in billed and accrued receivables, which is due in
part to the Company's emphasis on PUF contracts rather than ILF/MLF contracts.

     An important contributor to the cash management program is the Company's
factoring of accrued receivables, whereby an interest in its accrued receivables
is transferred on a non-recourse basis to third-party financial institutions in
exchange for cash. During the first quarter of fiscal 2002 and 2001, the Company
generated operating cash flows from the factoring of accrued receivables of $5.8
million and $3.1 million, respectively.

     The Company's net cash flows used in investing activities totaled $3.4
million and $5.0 million during the first quarter of fiscal 2002 and 2001,
respectively. The decrease in cash used in investing activities was due to
decreased additions of investments, notes receivable and software, offset by
increased purchases of property and equipment.

     The Company's net cash flows used in financing activities was $5.9 million
for the first quarter of fiscal 2002. Net cash provided by financing activities
was $11.1 million in the first quarter of fiscal 2001. During the first quarter
of fiscal 2002, the Company had net payments on its bank line of credit
facilities of $7.0 million as compared to net borrowings of $10.8 million during
the comparable period of fiscal 2001.

     The Company believes that its existing sources of liquidity, including cash
provided by operating activities along with cash generated from its factoring
program and borrowings available under its credit facilities, will satisfy the
Company's projected working capital and other cash requirements for the
foreseeable future.

Forward-Looking Statements

     This report contains forward-looking statements based on current
expectations that involve a number of risks and uncertainties. Generally,
forward-looking statements include words or phrases such as "management
anticipates," "the Company believe," "the Company anticipates," "the Company
expects," "the Company plans," "the Company will," and words and phrases of
similar impact, and include but are not limited to statements regarding
operations, business strategy and business environment. The forward-looking
statements are made pursuant to safe harbor provisions of the Private Securities
Litigation Reform Act of 1995. Actual results could differ materially. Factors
that could cause actual results to differ include, but are not limited to, the
following:

     o   The Company will continue to derive a majority of its total revenue
         from international operations and is subject to risks of conducting
         international operations including: difficulties in staffing and
         management, reliance on independent distributors, longer payment
         cycles, volatilities of foreign currency exchange rates, compliance
         with foreign regulatory requirements, variability of foreign economic
         conditions, and changing restrictions imposed by U.S. export laws.

     o   The Company will continue to derive a substantial majority of its total
         revenue from licensing its BASE24 family of software products and
         providing services and maintenance related to those products. Any
         reduction in demand for, or increase in competition with respect to,
         BASE24 products would have a material adverse effect on the Company's
         financial condition and results of operations.

     o   The  Company  will  continue  to derive a  substantial  portion  of its
         revenues  from  licensing of software  products  that operate on Compaq
         computers.  Any reduction in demand for these  computers or in Compaq's
         ability to deliver  products  on a timely  basis  could have a material
         adverse  effect on the  Company's  financial  condition  and results of
         operations.  Compaq has  announced  that it is planning to  consolidate
         its  high-end  performance   enterprise  servers  on  the  Intel  Corp.
         Itanium  microprocessor  by  2004.  Also,  Compaq  is  contemplating  a
         merger  with   Hewlett-Packard  Co.  The  Company  has  not  determined
         whether the  consolidation  of the  high-end  servers,  if it occurs as
         announced,  or the merger, if consummated,  would materially affect the
         Company's business, financial position or results of operations.

     o   The Company's business is concentrated in the banking industry, making
         it susceptible to a downturn in that industry. Further, banks are
         continuing to consolidate, decreasing the overall number of potential
         buyers of TSA's products and services.

     o   New accounting standards, or additional interpretations or guidance
         regarding existing standards, could be issued in the future, which
         could lead to unanticipated changes in the Company's current financial
         accounting policies. These changes could affect the timing of revenue
         or expense recognition and cause fluctuations in operating results.

     o   Fluctuations in quarterly operating results may result in volatility in
         the Company's stock price. No assurance can be given that operating
         results will not vary. The Company's stock price may also be volatile,
         in part, due to external factors such as announcements by third parties
         or competitors, inherent volatility in the high-technology sector and
         changing market conditions in the industry.

     o   The  Company  has  expanded  and may seek to  continue  to  expand  its
         operations   through  the   acquisition   of   additional   businesses.
         Acquisitions  involve  many risks  that  could have a material  adverse
         effect on the Company's  business,  financial  condition and results of
         operations.  Management's  negotiations of potential  acquisitions  and
         the  integration of acquired  businesses or  technologies  could divert
         their  time and  resources.  Further,  the  Company  may not be able to
         properly   integrate   acquired   businesses  or  technology  with  its
         existing  operations,  train and motivate  personnel  from the acquired
         business, or combine potentially different corporate cultures.

     For a detailed discussion of these and other risk factors, interested
parties should review the Company's filings with the Securities and Exchange
Commission.
