(“ATA”), with a debtor-in-possession loan facility of up to $47 million. As required by the Bid Proposal, on December 23, 2004, ATA and Southwest entered into a Secured Debtor-In-Possession Credit and Security Agreement dated as of December 22, 2004 (the “DIP Facility”) that provides up to $40 million in cash to ATA plus a guaranty by Southwest of up to $7 million. During the term of the DIP Facility, ATA is subject to certain financial covenants.

On February 3, 2005, Southwest and the Company entered into a First Amendment to Credit Agreement (the “First Amendment”). Under the First Amendment, the DIP Facility was amended by changing the starting date for the periods in which the Minimum Consolidated EBITDARR and Minimum Adjusted EBITDARR financial covenants are effective from January 1, 2005, to February 1, 2005.

On February 28, 2005, Southwest and the Company entered into a Second Amendment to Credit Agreement (the “Second Amendment”). Under the Second Amendment, the DIP Facility was amended by changing the starting date for the periods in which the Minimum Consolidated EBITDARR and Minimum Adjusted EBITDARR financial covenants are effective from February 1, 2005, to March 1, 2005.

On April 15, 2005, Southwest and the Company entered into a Third Amendment to Credit Agreement (the “Third Amendment”). Under the Third Amendment, the DIP Facility was amended by changing the starting date for the periods in which the Minimum Consolidated EBITDARR and Minimum Adjusted EBITDARR financial covenants are effective from March 1, 2005, to April 1, 2005.

On May 12, 2005, Southwest and the Company entered into a Fourth Amendment to Credit Agreement (the “Fourth Amendment”). Under the Fourth Amendment, the DIP Facility was amended by changing the starting date for the periods in which the Minimum Consolidated EBITDARR and Minimum Adjusted EBITDARR financial covenants are effective from April 1, 2005, to May 1, 2005.

The First Amendment, Second Amendment, Third Amendment, Fourth Amendment and Sixth Amendment (collectively the “Amendments”) were subject to the consent of the Air Transportation Stabilization Board and the Official Creditors Committee for ATA in its Chapter 11 case, both of which consented to each of these Amendments.
