Statements in this press release and by Company executives regarding its implementation of new business strategies and its relationship with United Airlines, Inc., as well as regarding operations, earnings, revenues and costs, represent forward-looking information. A number of risks and uncertainties exist which could cause actual results to differ materially from these projected results. Such risks and uncertainties include, among others: United's option under bankruptcy rules to assume or reject the existing United Express Agreement, the timing of such decision, efforts by United to negotiate changes prior to making a decision on whether to affirm or reject the contract, the ability and timing of agreeing upon rates with United, the effect of any bankruptcy court review of the tentative agreement on 2003 rates, and the fact that the Company cannot predict the timing or outcome of United's decision process or required approvals; the timing and impact on the Company's ability to implement an alternative business plan of any disengagement by the Company as a United Express carrier; the continued financial health of Delta Air Lines, Inc.; the ability of these partners to manage their operations and cash flow, and ability and willingness of these partners to continue to deploy the Company's aircraft and to utilize and pay for scheduled service at agreed upon rates; general economic and industry conditions; additional acts of war; and risks and uncertainties arising from the events of September 11, the impact of the outbreak of Severe Acute Respiratory Syndrome on travel and from the slow economy, any of which may impact the Company, its aircraft manufacturers and its other suppliers in ways that the Company is not currently able to predict. Certain of these and other risk factors are more fully disclosed under "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in ACAI's Annual Report on Form 10-K for the year ended December 31, 2002 and in its Quarterly Report on Form 10-Q for the three- month period ended March 31, 2003.
