                      TRANSACTION SYSTEMS ARCHITECTS, INC.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


1.   Consolidated Financial Statements

     Transaction Systems Architects, Inc. ("TSA" or the "Company"), 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 March 31, 2002, and for
the three and six months ended March 31, 2002 and 2001, 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 and six months ended
March 31, 2002 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

                                        6



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 recognized during the three
months ended March 31, 2002 and 2001 totaled approximately $2.8 million and $2.8
million, respectively. The present value of Recognized-Up-Front MLFs recognized
during the six months ended March 31, 2002 and 2001 totaled approximately $6.9
million and $11.9 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 7.00% to 9.25% during the six months
ended March 31, 2002, and from 9.50% to 11.00% during the six months ended March
31, 2001. 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 $4.3
million as of March 31, 2002. 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 Company is in compliance with all debt
covenants as of March 31, 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." The Company recorded interest expense
of $36,000 and $527,000 during the three months ended March 31, 2002 and 2001,
respectively, and $164,000 and $1,020,000 during the six months ended March 31,
2002 and 2001, 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. The Company has no line of credit borrowings
outstanding as of March 31, 2002. The entire $29.3 million is available to the
Company for future borrowings. The U.S. credit facility expires in June 2002 and
the foreign credit facility expires in October 2002. The Company plans to renew
both lines of credit with financial terms similar to those currently in place.

4.   Gain on Sale of Subsidiary

     On February 14, 2002, the Company sold Regency Systems, Inc. ("Regency"),
which sells voice and Internet banking solutions to small and mid-sized banks,
to S1 Corporation ("S1"). Under the terms of the transaction, S1 acquired
Regency for 400,561 unregistered shares of S1 common stock and $6.0 million in
cash ($5.0 million net of expenses associated with the sale). S1 shares are
included in marketable securities and recorded at current market value. Pursuant
to the Stock Purchase Agreement, S1 was required to file a registration
statement on Form S-3 with the Securities and Exchange Commission ("SEC") to
register the resale of these shares. In the event that the fair value of the S1
common stock received (valued at the average closing price per share for S1
common stock for the last 10 trading days immediately preceding the date the
registration statement is declared effective by the SEC) is less than $5.1
million, or $12.73 per share, then S1 shall owe the Company, within five trading
days, the difference between $5.1 million and the fair value in cash, S1 common
stock, or any combination thereof, at S1's option. In connection with this
transaction, the Company recorded a gain of $4.1 million.

5.   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

                                        8



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 six months of
fiscal 2002, the Company reduced the liability related to these items by
approximately $2.0 million. The Company expects approximately $0.9 million of
the remaining $2.0 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.

6.   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 during the first quarter of fiscal 2002 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.

7.   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 March 31, 2002 condensed consolidated balance sheets, and are included
in common shares outstanding for earnings per share ("EPS") computations for the
three and six months ended March 31, 2002 and 2001. Exchangeable shares and MDL
options included in Class A Common Stock totaled 503,267 shares and 15,459
options as of March 31, 2002, 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

                                       10



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). There is no difference in the
numerator used for basic and diluted EPS computations. The differences between
the basic and diluted EPS denominators for the three and six months ended March
31, 2002, which amounted to approximately 232,000 and 219,000 shares,
respectively, were due to the dilutive effect of the Company's outstanding stock
options using the treasury stock method. Weighted average shares from stock
options of 1,680,000 and 1,666,000 were excluded from the computation of diluted
EPS for the three and six months ended March 31, 2002, respectively, because the
exercise prices of the stock options were greater than the average market price
of the Company's common shares. For the three and six months ended March 31,
2001, basic and diluted EPS are the same, as any outstanding dilutive securities
were antidilutive due to the net loss from continuing operations in both
periods.

10.  Stock-Based Compensation

     On August 1, 2001, the Company announced a voluntary stock option exchange
program (the "Exchange Program") offering to exchange all outstanding options to
purchase shares of the Company's Class A Common Stock ("Common Stock") granted
under the 1994 Stock Option Plan, 1996 Stock Option Plan and 1999 Stock Option
Plan held by eligible employees or eligible directors for new options under the
same option plans. The Exchange Program required that any person tendering an
option grant for exchange would be required to also tender all subsequent option
grants with a lower exercise price received by that person during the six months
immediately prior to the date the options accepted for exchange are cancelled.
Options to acquire a total of 3,089,100 shares of Common Stock with exercise
prices ranging from $2.50 to $45.00 were eligible to be exchanged under the
Exchange Program. The offer expired on August 28, 2001, and the Company canceled
1,946,550 shares tendered by 578 employees. As a result of the Exchange Program,
the Company granted replacement stock options to acquire 1,823,000 shares of
Common Stock at an exercise price of $10.04. The difference between the number
of shares cancelled and the number of shares granted relates to options
cancelled by employees who terminated their employment with the Company between
the cancellation date and the regrant date. The exercise price of the
replacement options was the fair market value of the Common Stock on the grant
date of the new options, which was March 4, 2002 (a date at least six months and
one day after the date of cancellation). The new shares have a vesting schedule
of 1/18 per month beginning on the grant date of the new options, except for
options tendered by executive officers under the 1994 Stock Option Plan, which
vest 25% annually on each anniversary of the grant date of the new options. The
Exchange Program was designed to comply with the Financial Accounting Standards
Board Interpretation No. 44, "Accounting for Certain Transactions Involving
Stock Compensation," and is not expected to result in any additional
compensation charges or variable-award accounting.

Item 2.  Management's Discussion and Analysis of Financial Condition and
          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
through distribution networks covering three geographic regions: the Americas,
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.

     The following are revenues and operating income (loss) for these business
units for the three and six months ended March 31, 2002 and 2001 (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.

revenue backlog, by business unit, as of March 31, 2002 and 2001 (in thousands):

     Revenues. Total revenues for the second quarter of fiscal 2002 decreased
$10.8 million, or 14.1%, from the comparable period in fiscal 2001. Total
revenues for the first six months of fiscal 2002 decreased $20.1 million, or
13.3%, from the comparable period in fiscal 2001. The three-month decrease is
the result of a $9.6 million, or 21.2%, decrease in software license fees
revenue and a decrease of $3.5 million, or 24.9%, decrease in services revenue
offset by a $2.2 million, or 12.7%, increase in maintenance fees revenue. The
six-month decrease is the result of a $17.7 million, or 20.2%, decrease in
software license fees revenue and a decrease of $8.2 million, or 27.1%, decrease
in services revenue offset by a $5.7 million, or 17.1%, increase in maintenance
fees revenue. Approximately $0.8 million of the decrease in total revenues for
the second quarter and first six months of fiscal 2002 was due to the sale of
Regency Systems, Inc. ("Regency"), which was part of the ACI Worldwide business
unit.

    The decrease in software license fee revenues for the second quarter and
first six months of fiscal 2002, as compared to the same periods in fiscal 2001,
is primarily the result of a decrease in demand for ACI Worldwide's and
Insession Technologies' products, offset by an increase in demand for IntraNet,
Inc.'s products.

    The decrease in demand for ACI Worldwide's products is due to fewer
transaction volume upgrades received during the second quarter and first six
months of fiscal 2002 as compared to the same periods in fiscal 2001. These
decreases are 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.

    The decrease in Insession Technologies' software license fees revenues is
primarily due to a decrease in demand for its ICE product line. This decrease in
demand has been caused by the same global economic conditions facing ACI
Worldwide.

    The increase in IntraNet, Inc.'s software license fees revenues is primarily
the result of migrating its customers from the Digital VAX-based MTS product to
the new RS6000-based MTS product.

    In fiscal 2001, the Company changed its sales compensation plans for its ACI
Worldwide and Insession Technologies sales forces to emphasize Paid-Up-Front
("PUF") contracts for both customer renewals and new customers rather than
emphasizing combination Initial License Fee and Monthly License Fee ("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 second quarter and first six months
of fiscal 2002, as compared to the same periods in fiscal 2001, resulted from
lower demand for technical and project management services, which was primarily
caused by decreased sales of ACI Worldwide's products and Insession
Technologies' 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 second quarter of fiscal 2002
decreased $10.3 million, or 13.9%, as compared to the second quarter of fiscal
2001 (excluding $3.4 million of goodwill amortization charges in the second
quarter of fiscal 2001). Total operating expenses for the first six months of
fiscal 2002 decreased $20.4 million, or 13.6%, as compared to the first six
months of fiscal 2001 (excluding $5.8 million of goodwill amortization charges
in the first six months 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. Approximately $1.1 million of
the decrease in operating expenses for the second quarter and first six months
of fiscal 2002 was due to the sale of Regency.

     Cost of software license fees for the second quarter of fiscal 2002
decreased $2.1 million, or 18.5%, as compared to the second quarter of fiscal
2001. Cost of software license fees for the first six months of fiscal 2002
decreased $2.7 million, or 11.7%, as compared to the first six months of fiscal
2001. These decreases were 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.

                                       16


     Cost of maintenance and services for the second quarter of fiscal 2002
decreased $2.2 million, or 12.4%, as compared to the second quarter of fiscal
2001. Cost of maintenance and services for the first six months of fiscal 2002
decreased $5.2 million, or 14.1%, as compared to the first six months of fiscal
2001. These decreases were the result of fewer staff needed to support the
Company's ACI Worldwide and Insession Technologies services-related business.

     Research and development ("R&D") costs for the second quarter of fiscal
2002 decreased $1.8 million, or 16.8%, as compared to the second quarter of
fiscal 2001. R&D costs for the first six months of fiscal 2002 decreased $2.8
million, or 13.6%, as compared to the first six months 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 three and six months ended March 31, 2002 were 13.6%
and 13.7%, respectively, as compared to 14.0% and 13.8%, respectively for
comparable periods 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
six months of fiscal 2002 and 2001 totaled approximately $0.6 million and $2.6
million, respectively.

     Selling and marketing costs for the second quarter of fiscal 2002 decreased
$1.8 million, or 9.7%, as compared to the second quarter of fiscal 2001. Selling
and marketing costs for the first six months of fiscal 2002 decreased $4.8
million, or 12.7%, as compared to the first six months of fiscal 2001. Selling
and marketing costs as a percentage of total revenues for the first six months
of fiscal 2002 were 25.3% compared to 25.1% for the first six months of fiscal
2001.

     General and administrative costs for the second quarter of fiscal 2002
decreased $2.4 million, or 15.0%, as compared to the second quarter of fiscal
2001. General and administrative costs for the first six months of fiscal 2002
decreased $4.9 million, or 15.2%, as compared to the first six months of fiscal
2001. These decreases were 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 the repayment of borrowings on the Company's line of
credit facilities, resulting in decreased interest expense, as well as an
increase in interest income resulting from an increase in the Company's cash
balance.

     The Company recorded a gain on sale of Regency in the amount of $4.1
million during the three months ended March 31, 2002. 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 six months of fiscal
2002 was approximately 17% as compared to 10% for the first six months of fiscal
2001. The Company adopted SFAS No. 142 (see Note 6 to the Condensed Consolidated
Financial Statements 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 six months of fiscal
2002 is lower than would be expected as the Company recorded a valuation reserve
against a portion of this tax benefit.

     Each quarter, the Company evaluates its historical operating results as
well as its projections for the future to determine the realizability of its
deferred tax assets. As of March 31, 2002, the Company has deferred tax assets
of $27.8 million (net of $25.9 million valuation allowance) and deferred tax
liabilities of $0.5 million. The Company intends to analyze the realizability of
its 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.

                                       17


Liquidity and Capital Resources

     As of March 31, 2002, the Company's principal sources of liquidity
consisted of $47.3 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 $4.3 million as of March 31, 2002. The foreign
credit agreement requires the Company to maintain minimum tangible net worth
within the Company's wholly-owned subsidiary, ACI Worldwide (EMEA) Ltd. There
are no line of credit borrowings outstanding as of March 31, 2002. The entire
$29.3 million is available to the Company for future borrowings. The Company is
in compliance with all debt covenants as of March 31, 2002. The U.S. credit
facility expires in June 2002 and the foreign credit facility expires in October
2002. Although no assurances can be given, the Company currently does not
anticipate circumstances that would lead to the non-renewal of either of these
line of credit agreements.

     The Company's net cash flows provided by operating activities for the first
six months of fiscal 2002 amounted to $25.4 million. Net cash used in operating
activities during the first six months of fiscal 2001 was $1.0 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 license term
whereas under the ILF/MLF payment option, the licensee pays a portion of the
software license fees at the beginning of the software license term and the
remaining portion over the software license term. The improvement in operating
cash flows in the first six months of fiscal 2002 as compared to the first six
months of fiscal 2001 is due to improvements in operating profits and 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 has been 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. The Company did not factor any accrued
receivables during the second quarter of fiscal 2002. During the first six
months of fiscal 2002 and 2001, the Company generated operating cash flows from
the factoring of accrued receivables of $5.8 million and $8.5 million,
respectively.

     The Company's net cash flows provided by investing activities totaled $0.8
million for the first six months of fiscal 2002 as compared to net cash flows
used in investing activities of $6.0 million during the comparable period of
fiscal 2001. Cash used in investing activities decreased by $2.4 million during
the first six months of fiscal 2002 as compared to the same period in fiscal
2001 due to decreased additions of investments, notes receivable and software,
offset by increased purchases of property and equipment. Additionally, the
Company received cash of $0.6 million from an acquisition completed during the
first six months of fiscal 2001. The Company also realized net proceeds of $5.0
million related to the sale of Regency during the second quarter of fiscal 2002.

     The Company's net cash flows used in financing activities totaled $10.7
million for the first six months of fiscal 2002 as compared to net cash flows
provided by financing activities of $4.7 million during the comparable period of
fiscal 2001. During the first six months of fiscal 2002, the Company made
payments on its bank line of credit facilities of $12.0 million as compared to
net borrowings of $3.3 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.

                                       18


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.  Hewlett-Packard  Company  announced on May 3, 2002 that it
         completed  its merger  transaction  with  Compaq.  Prior to the merger,
         Compaq  announced  a  plan  to  consolidate  its  high-end  performance
         enterprise servers on the Intel Corp.  Itanium  microprocessor by 2004.
         The  Company   has  not   determined   whether   the  merger,   or  the
         consolidation of the high-end  servers if it occurs as announced,  will
         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.
