New Credit Facilities

American Airlines, Inc. (“American”) is currently contemplating entering into new secured credit facilities (the “New Credit Facilities”) with Citigroup Global Markets Inc. as the Lead Arranger and a group of lenders to be determined. The New Credit Facilities are currently anticipated to (a) consist of a term loan of $1 billion and a revolving credit facility of $800 million, (b) mature seven years (in the case of the term loan) and five years (in the case of the revolving credit facility) after they are entered into, (c) be guaranteed by AAG, US Airways Group and US Airways, (d) be secured by liens on certain route authorities, slots and foreign gate leaseholds and (e) generally include customary affirmative, negative and financial covenants, events of default and other terms. AAG anticipates that proceeds from borrowings under the New Credit Facilities would be used for general corporate purposes. The timing of any such transaction is uncertain, and there can be no assurance the New Credit Facilities will be consummated in the amounts or on the other terms described above or at all.
