Any statements in this press release regarding projected results are preliminary and "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. In addition, this press release may contain other forward-looking statements including statements regarding Transaction Systems Architects, Inc.'s ("TSA"), its subsidiaries or third parties' expectations, predictions, views, opportunities, plans, strategies, beliefs, and statements of similar effect. The forwarding-looking statements in this press release are subject to a variety of risks and uncertainties. Actual results could differ materially. Factors that could cause actual results to differ include but are not limited to the following.

The success of TSA, or any of its subsidiaries, entering into a new distribution or partnering arrangement depends on numerous factors including the acceptance of the distributed products or services by TSA's existing customer base and integration of the products and services into TSA's marketing efforts, the quality of the products or services as perceived after use by TSA's customers, and the degree of competition from competitive products or service providers.

TSA's business is concentrated in the banking industry, making it susceptible to a downturn in that industry.

TSA is subject to risks of conducting international operations including: difficulties in staffing and management, reliance on independent distributors, fluctuations in foreign currency exchange rates, compliance with foreign regulatory requirements, variability of foreign economic conditions, and changing restrictions imposed by U.S. export laws.

Fluctuations in quarterly operating results may result in volatility in TSA's stock price. No assurance can be given that operating results will not vary. TSA'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.

For a detailed discussion of these and other risk factors, interested parties should review TSA's filings with the Securities and Exchange Commission, including Exhibit 99.01 to TSA's Annual Report on Form 10-K for the fiscal year ended September 30, 2000.
