C. Statutory and Rule Predicates. The statutory predicates for the relief sought in the Motion are sections 105(a), 363(b), and 503(b) of the Bankruptcy Code and Bankruptcy Rules 2002 and 6004.

D. Notice. As set forth in the Motion and evidenced by the affidavits of service filed with the Court, due, proper, timely, adequate, and sufficient notice of the Motion and the Merger Agreement has been provided in accordance with the Court’s Order Approving Form and Manner of Notice With Respect to the Motion of Debtors for Entry of Order Pursuant to 11 U.S.C. §§ 105(a), 363(b), and 503(b) Authorizing and Approving (I) Merger Agreement Among AMR Corporation, AMR Merger Sub, Inc., and US Airways Group, Inc., (II) Debtors’ Execution of and Performance Under Merger Agreement, (III) Certain Employee Compensation and Benefit Arrangements, (IV) Termination Fees, and (V) Related Relief, and Scheduling Evidentiary Hearing and Setting Objection Deadline With Respect Thereto, dated February 21, 2013 (ECF No. 6777).

E. Opportunity to Object. A reasonable opportunity to object to and to be heard with respect to the Motion and the relief requested has been given as required by the Bankruptcy Code and the Bankruptcy Rules to all persons entitled to notice.

F. Business Justifications. The Debtors have demonstrated good and sufficient business justification for approval of the Motion and the Merger Agreement and authorization to take the actions contemplated thereby or in connection therewith. The Debtors’

entry into and performance under the Merger Agreement (i) constitute a sound and reasonable exercise of the Debtors’ business judgment, (ii) provide value to and are beneficial to the Debtors’ estates, and are in the best interests of the Debtors and their stakeholders, and (iii) are reasonable and appropriate under the circumstances.

G. Alternative Transaction Procedures and Termination Fees. The alternative transaction procedures and the termination fees provided for in the Merger Agreement and described in Sections D and I of the Motion are an integral part of the transactions contemplated by the Merger Agreement, and the Debtors represent that, without these undertakings, the Debtors and US Airways would not have entered into the Merger Agreement or pursued the Merger. The termination fees are reasonable and appropriate in light of the size and nature of the Merger and the undertakings of the parties in connection therewith, including the considerable time and expense expended and likely to continue to be expended by the Debtors and US Airways with respect to the Merger Agreement.

H. Employee Arrangements. Because of the nature of the Merger, the necessity for a smooth transition and to successfully effect the Merger as seamlessly as possible, the employment uncertainty and insecurity faced by employees, and the critical role that employees have in the maintenance and preservation of enterprise value, the Employee Arrangements approved herein, except as provided for in paragraph 6 below, are reasonable and appropriate under the circumstances, and are necessary for the preservation of the value of the Debtors’ estates, including for purposes of section 280G and 4999 of the Tax Code.

I. Arm’s-Length Transaction and Good Faith. The Merger Agreement was negotiated, proposed, and entered into by the Debtors and US Airways in good faith, without collusion, and from arm’s-length bargaining positions. Each of the parties was represented by competent legal and financial professionals with respect to the Merger Agreement and the transactions contemplated thereby.

4. Termination Fees. If any of the American No Vote Transaction Fee, the American Alternative Transaction Fee or the American Termination Fee (as each of such terms is defined in the Merger Agreement) become payable pursuant to the terms of the Merger Agreement, such fee shall constitute an allowed administrative expense against AMR; provided, however, that such fee shall be appropriately allocated among the Debtors.

The foregoing authorization shall include, without limitation, providing or making any necessary or appropriate disclosures, filings, reports, registrations, and notices or obtaining any necessary or appropriate approvals, consents, permits, or authorizations of any third party or governmental entities or agencies for the Merger, including, without limitation, under the Hart Scott Rodino

b. Notwithstanding anything to the contrary in this Order, to the extent that the effectuation of any transactions contemplated by the Merger Agreement shall be subject to the parties’ obtaining any approvals, consents, permits, or authorizations that may be required by any governmental unit, nothing herein shall be deemed to grant any such approvals, consents, permits or authorizations.

c. Nothing in this Order or the Merger Agreement releases, nullifies, precludes or enjoins the enforcement of any liability or obligation to a governmental unit under police and regulatory statutes or regulations (including but not limited to environmental laws or regulations), and any associated liabilities for penalties, damages, cost recovery, or injunctive relief that any entity would be subject to as the owner, lessor, lessee, or operator of any property that is transferred pursuant to the Merger Agreement.
