Private Securities Litigation Reform Act of 1995 Safe Harbor For Forward-Looking Statements 2 This communication contains forward-looking statements based on current expectations that involve a number of risks and uncertainties. All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements, including statements about the planned completion of the tender offer and the merger, estimates of revenues, operating margins, capital expenditures, cash, other financial metrics, expected legal, arbitration, political, regulatory results or practices, customer patterns or practices and other such estimates and results. No forward-looking statement can be guaranteed and actual results may differ materially from those that ACI Worldwide and Official Payments project. Numerous risks, uncertainties and other factors may cause actual results to differ materially from those expressed in any forward-looking statement, many of which are outside of the control of management. These factors include, but are not limited to: (1) the occurrence of any event, change or other circumstance that could give rise to the termination of the definitive agreement; (2) successful completion of the proposed transaction on a timely basis; (3) the impact of regulatory reviews on the proposed transaction; (4) the outcome of any legal proceedings that may be instituted against one or both of ACI Worldwide and Official Payments and others following the announcement of the definitive transaction agreement; (5) risks that the proposed transaction disrupts current plans and operations and the potential difficulties in employee retention as a result of the transaction; and (6) other factors described in ACI Worldwide's and Official Payments' filings with the SEC, including their respective reports on Forms 10-K, 10-Q and 8-K. Except to the extent required by applicable law, neither ACI Worldwide nor Official Payments undertakes any obligation to revise or update any forward- looking statements, or to make any other forward-looking statements, whether as a result of new information, future results or otherwise.
