Tudor Investment Agreement Effective as of July 7, 2005, US Airways Group, Inc., a Delaware corporation ("US Airways Group"), and America West Holdings Corporation, a Delaware corporation ("America West Holdings"), entered into an Investment Agreement (the "Tudor Agreement"), with Tudor Proprietary Trading, L.L.C. and certain investors listed on Schedule 1 to the Tudor Agreement for which Tudor Investment Corp. acts as investment adviser (collectively, the "Tudor Investors"). The Tudor Agreement contains terms substantially the same as the investment agreement previously entered into on May 27, 2005 by US Airways Group, America West Holdings and Wellington Management Company, LLP, on behalf of investors for which it acts as investment adviser (the "Wellington Agreement"), as described on the Form 8-K filed by America West Holdings on June 2, 2005, and the investment agreements entered into among America West Holdings, US Airways Group and certain equity investors on May 19, 2005 (the "May 19 Agreements," and together with the Wellington Agreement and the Tudor Agreement, the "Investment Agreements"), as described on the Form 8-K filed by America West Holdings on May 25, 2005. The transactions contemplated by the Tudor Agreement are expected to be consummated simultaneously with the closing under the Agreement and Plan of Merger (the "Merger Agreement") entered into on May 19, 2005 between America West Holdings, US Airways Group and Barbell Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of US Airways Group. The Merger Agreement provides that, upon the terms and subject to the conditions set forth in the Merger Agreement, Barbell Acquisition Corp. will merge with and into America West Holdings (the "Merger"), with America West Holdings continuing as a wholly owned subsidiary of US Airways Group. The Tudor Agreement provides that, upon the terms and subject to the conditions set forth in the Tudor Agreement, US Airways Group will sell to the Tudor Investors, and the Tudor Investors will purchase, shares of US Airways Group common stock for a per share purchase price of $16.50 and an aggregate purchase price of $65 million, payable in cash. The Tudor Investors, together with the investors who entered into the Wellington Agreement and the May 19 Agreements (collectively, the "Equity Investors"), have made equity commitments of $565 million in the aggregate. US Airways Group, America West Holdings and the Tudor Investors have each made customary representations, warranties and covenants in the Tudor Agreement. US Airways Group has made certain additional covenants not to issue or agree to issue additional equity securities of US Airways Group prior to the closing under the Tudor Agreement, other than: (i) under the Investment Agreements and to other equity investors on terms and conditions no more favorable than those contained in the Tudor Agreement and the stockholders agreement to be entered into in connection with the closing under those Investment Agreements (the "Stockholders Agreement"), and which, for agreements entered into on or prior to July 7, 2005, provide for up to an aggregate investment of $350 million at a purchase price of not less than $15.00 per share and up to an aggregate investment of $215 million at a purchase price of not less than $16.50 per share, and for agreements entered into after July 7, 2005, provide for up to an aggregate investment of $85 million at a purchase price of not less than $16.50 per share; (ii) pursuant to the Merger and the plan of reorganization (the "Plan") of US Airways Group and its domestic subsidiaries in connection with their voluntary petitions for reorganization pursuant to chapter 11 of title 11 of the United States Code, 11 U.S.C. Sections 101 et seq. (the "Bankruptcy Code") in the United States Bankruptcy Court for the Eastern District of Virginia, Alexandria Division (the "Bankruptcy Court"); (iii) for proceeds not to exceed the difference between the amount raised pursuant to (i) above and $800 million (which may be pursuant to a rights offering) at a price per share of no less than $16.50 and, except with respect to the rights offering, on other terms and conditions that are no more favorable to the purchasers of those shares than the terms and conditions provided in the Tudor Agreement and in the Stockholders Agreement are to the Tudor Investors. In addition the use of proceeds in excess of $650 million (including amounts raised pursuant to (i) above as well as this paragraph (iii)) is limited to the repurchase of equity securities of US Airways Group (including securities of America West Holdings convertible into or exchangeable for US Airways Group equity securities as a result of the Merger) expected to be outstanding on the effective date of the Merger at a repurchase price that implies a per share value of no more than $16.50. US Airways Group may use the proceeds for general corporate purposes, however, if it obtains the consent of at least two-thirds of the Equity Investors for amounts in excess of $650 million and up to $725 million, and at least three-quarters of the Equity Investors for proceeds in excess of $725 million and up to $800 million. Furthermore, if US Airways Group repurchases equity securities from any Equity Investor, that repurchase may only be done (A) with the consent of that Equity Investor, (B) at a purchase price per share equal to the price per share payable by that Equity Investor pursuant to the Equity Investor's respective Investment Agreement and (C) if that Equity Investor waives any break-up or similar fee otherwise payable to the Equity Investor. In addition, the first $50 million of any such repurchase from an Equity Investor must be offered first to Eastshore Aviation, LLC before any other Equity Investor, and Eastshore Aviation, LLC will have the right, but not the obligation, to accept that offer to repurchase in whole or in part for a period of at least 30 days after the receipt of the offer. Under the Tudor Agreement, each Tudor Investor is also granted the option, exercisable on or prior to the expiration date of the rights offering or on the closing date of the Merger if no rights offering takes place (the "Option Expiration Date"), to purchase at $15.00 per share up to the number of additional shares of new common stock of US Airways Group equal to that Tudor Investor's Option Amount divided by $15.00. The "Option Amount" is 20% of the Tudor Investor's aggregate purchase price set forth on Schedule 1 to the Tudor Agreement multiplied by a fraction, the numerator of which is the amount of equity raised from the Tudor Investors pursuant to the Tudor Agreement plus the amount of equity raised pursuant to (i) and (iii) above after July 7, 2005 up to an aggregate for the numerator of $150 million, and the denominator of which is $150 million. This option is transferable, in whole or in part, among the Equity Investors. In addition, the Tudor Agreement also provides that upon the Option Expiration Date, US Airways Group may make an offer to Eastshore, in an amount equal to one-third of the proceeds received from exercise of the options (together with the exercise of the options granted to the other Equity Investors pursuant to the Letter Agreement described below), to repurchase shares of US Airways Group common stock held by Eastshore at a purchase price of $15.00 per share, and Eastshore will have the right, but not the obligation, to accept that offer to repurchase in whole or in part for a period of at least 30 days after the receipt of the offer. In addition, the Tudor Agreement provides that in connection with the implementation of the Plan, US Airways Group may authorize and reserve for issuance under its equity incentive plan a number of shares of new common stock not to exceed 12.5% of the outstanding number of shares of new common stock on a fully diluted basis as of the effective date of the Merger (the "Employee Pool"). Any awards of these shares made or committed to be made at anytime before the second anniversary of the effective date of the Merger must: (i) if in the form of options, have an exercise price not less than the lesser of (a) fair market value as of the date of grant and (b) $16.50 (as appropriately adjusted to reflect stock splits, stock dividends, reverse splits and similar changes with respect to the new common stock effected after the closing of the Merger), provided that the exercise price for any options granted as of or immediately following the effective date of the merger may not be less than $16.50; (ii) if in the form of restricted stock, reduce the number of shares in the Employee Pool by three for each share of restricted stock issued; and (iii) in the case of either (i) or (ii), not be effective unless those awards are approved or ratified by the Board of Directors as constituted pursuant to the terms of the Merger Agreement, or by a committee with appropriate authority granted by that Board. Completion of the transactions under the Tudor Agreement is subject to customary conditions, including, among others, (i) execution and delivery of definitive transaction documents related to the investment by the Tudor Investors and approval of those documents, to the extent necessary, by the Bankruptcy Court, (ii) subject to certain exceptions, the accuracy of representations and warranties with respect to the business of America West Holdings or US Airways Group, as applicable, or with respect to certain matters by the Investors, (iii) the absence of any law or order enjoining the performance of any of the transaction documents, (iv) no governmental entity having instituted any proceeding seeking any order which would prevent the performance of any of the transaction documents, (v) the absence of any pending or threatened litigation which, if determined adversely to US Airways Group, would materially impair or limit the right of the Tudor Investors under the transaction documents, which the Tudor Investors reasonably determine has a reasonable likelihood of success, (vi) expiration or termination of the applicable Hart-Scott-Rodino Act waiting period and the receipt of certain other regulatory approvals, (vii) Bankruptcy Court approval of the Plan and that Plan not being in conflict with any of the transaction documents and being consistent with the financial plan provided to the Tudor Investors, and (viii) the Merger becoming effective simultaneously with the closing under the Investment Agreements. In addition, the obligation of the Tudor Investors to consummate the transactions contemplated by the Tudor Agreement is subject to, among other things, (i) all material contracts necessary for the successful implementation of the Plan having been assumed, assigned, rejected or renegotiated, as applicable, (ii) receipt by US Airways Group of equity investments of not less than $375 million or more than $800 million (including the conversion of the Eastshore Aviation, LLC debtor in possession credit agreement), subject to certain exceptions, (iii) the bankruptcy cases of US Airways Group and its domestic subsidiaries not having been converted to a case under chapter 7 of the Bankruptcy Code, (iv) US Airways Group having obtained directors and officers insurance of at least $100 million, (v) there not having occurred any change or event that could reasonably be expected to have a material adverse effect on the financial condition, assets, liabilities, business or results of operations of US Airways Group or America West Holdings, (vi) the amendment of US Airways Group's employee profit sharing plan in the manner specified in the Tudor Agreement, and (vii) the listing of the shares of common stock to be issued under the Tudor Agreement on the New York Stock Exchange or Nasdaq Stock Market. The Tudor Agreement contains certain termination rights for US Airways Group and the Tudor Investors. Unlike the May 19 Agreements, the Tudor Agreement does not contain terms that provide for payment of a termination fee to the Tudor Investors upon termination of the Tudor Agreement under specified circumstances. The Tudor Investors will not be entitled to designate any individual to be appointed to the board of directors of US Airways Group as of the effective time of the Merger. A copy of the Tudor Agreement is attached hereto as Exhibit 10.1 and is incorporated herein by reference. The description of the Tudor Agreement is qualified in its entirety by reference to the full text of the Tudor Agreement. The Tudor Agreement contemplates that at the closing thereunder, the Tudor Investors and US Airways Group will enter into the Stockholders Agreement along with the other Equity Investors. The Stockholders Agreement will provide that, subject to certain exceptions, the Tudor Investors will agree not to transfer any of the shares of US Airways Group common stock acquired pursuant to the Tudor Agreement until six months following the closing under the Tudor Agreement and that US Airways Group will provide certain customary registration rights to the Tudor Investors. Letter Agreement Amending the Merger Agreement and Other Investment Agreements Effective as of July 7, 2005, US Airways Group, America West Holdings, Barbell Acquisition Corp. and each of the Equity Investors (other than the Tudor Investors), including ACE Aviation Holdings Inc. ("ACE"), Eastshore Aviation, LLC ("Eastshore"), Par Investment Partners, L.P. ("Par"), Peninsula Investment Partners, L.P. ("Peninsula") and Wellington Management Company, LLP on behalf of certain investors for whom it acts as an investment adviser (the "Wellington Investors"), entered into a letter agreement (the "Letter Agreement") amending the Merger Agreement and the Investment Agreements (other than the Tudor Agreement, which already contains the applicable provisions discussed below). The key provisions of the Letter Agreement are as follows: (1) Clarification that the Wellington Investors and the Tudor Investors are considered "Equity Investors" and that each of the Wellington Agreement and Tudor Agreement are considered "Financing Commitments" for the purposes of the Merger Agreement. (2) Clarification of the provisions of the Merger Agreement with respect to the appointment of directors of US Airways Group at the effective time of the Merger, to affirmatively state that the Wellington Investors and Tudor Investors are not entitled to board representation and to clarify that if, prior to the closing, another investor agrees to invest more than $75 million, becomes entitled to designate a director and wishes to do so, ACE will waive its right to designate a director to accommodate the new equity investor. (3) Amendment of the merger exchange ratio for the America West Holdings Class A common stock from 0.5306 to 0.5362 and the merger exchange ratio for the America West Holdings Class B common stock from 0.4082 to 0.4125 to give effect to adjustment provided for below with respect to the Wellington Agreement. In addition, the number of shares expected to be outstanding upon the closing of the Merger Agreement and effectiveness of the Plan is amended from 47,475,729 to 59,642,591 to reflect the investments by the Wellington Investors and Tudor Investors. (4) Amendment of the provisions of section 4.20 of the Merger Agreement relating to additional shares to be issued to Par and Peninsula if US Airways Group enters into an alternative transaction to the Merger to clarify which transactions qualify as alternative transactions. In addition, the Letter Agreement specifies that as a result of the Wellington Agreement, and not pursuant to section 4.20 of the Merger Agreement, upon closing of the investment under the Wellington Agreement, additional shares of common stock will be allocated to the creditors of US Airways Group, the stockholders of America West Holdings, and Par, in the amounts of 545,454 shares, 261,818 shares and 101,818 shares, respectively. (5) The covenant of US Airways Group in the Investment Agreements not to issue or agree to issue additional equity securities of US Airways Group prior to the closing of the Investment Agreements are amended to correspond with the comparable provisions in the Tudor Agreement, as described above. In addition, under the Letter Agreement, US Airways Group agreed to grant to each of the Equity Investors other than the Tudor Investors an option comparable to the option granted to the Tudor Investors in the Tudor Agreement. The option is exercisable on or prior to the Option Expiration Date (as defined above), and gives the Equity Investor the right to purchase at $15.00 per share up to the number of additional shares of common stock equal to that Equity Investor's Option Amount divided by $15.00 and otherwise on the same terms and conditions as that Equity Investor's Investment Agreement. The "Option Amount" is the amount set forth next to each Equity Investor's name in the table below multiplied by a fraction, the numerator of which is the amount of equity raised from the Tudor Investors plus the amount of equity raised after July 7, 2005 pursuant to any equity investments and the rights offering up to an aggregate for the numerator of $150 million, and the denominator of which is $150 million. --------------------------------------|-------------------- Par Investment Partners, L.P. |$20 million --------------------------------------|-------------------- Peninsula Investment Partners, L.P. |$10 million --------------------------------------|-------------------- ACE Aviation Holdings Inc. |$15 million --------------------------------------|-------------------- Eastshore Aviation, LLC |$25 million --------------------------------------|-------------------- Wellington Investors |$30 million --------------------------------------|-------------------- Each option is transferable, in whole or in part, among the Equity Investors. The Letter Agreement also provides that upon the Option Expiration Date, US Airways Group will make an offer to Eastshore, in an amount equal to one-third of the proceeds received from exercise of the options (together with the exercise of the option pursuant to the Tudor Agreement and any similar option granted to other equity investors who invest after July 7, 2005), to repurchase shares of common stock held by Eastshore at a purchase price of $15.00 per share, and Eastshore will have the right, but not the obligation, to accept that offer to repurchase in whole or in part for a period of at least 30 days after the receipt of the offer. In addition, certain schedules of the Merger Agreement are amended by the Letter Agreement to reflect the investments under the Wellington Agreement and the Tudor Agreement. A copy of the Letter Agreement is attached hereto as Exhibit 10.2 and is incorporated herein by reference. The description of the Letter Agreement is qualified in its entirety by reference to the full text of the Letter Agreement. Amended and Restated Participation Agreements In addition, on July 7, 2005, each of Par and Peninsula entered into an amended and restated Participation Agreement (the "Amended Participation Agreements") with America West Holdings, which amended and restated the Participation Agreements entered into by such parties on May 19, 2005 in connection with the execution and delivery by Par and Peninsula of their respective Investment Agreements. The Amended Participation Agreements provide that, unless the Merger Agreement is terminated by US Airways Group or America West Holdings because America West Holdings enters into a superior alternative business combination transaction, neither Par nor Peninsula will make, directly or indirectly, any debt or equity investment in US Airways Group or provide, directly or indirectly, equity or debt financing for the purposes of funding a reorganization, business combination transaction or stand-alone plan of US Airways Group with respect to which America West Holdings is not involved. The Amended Participation Agreements also provide that, subject to certain limitations, in the event that America West Holdings is a party to or otherwise involved in, an alternative reorganization or business combination transaction involving the sale of US Airways Group common stock at a price greater than $15.00 per share and the transactions contemplated by the Par and Peninsula Investment Agreements are not consummated, America West Holdings will cause the Merger Agreement (or other applicable agreement) or the Plan to provide that, at the closing of such an alternative transaction, US Airways Group will issue shares of US Airways Group common stock (valuing such shares of at $15.00 per share for such purpose) representing an aggregate of 11.2% of the Additional Pre-Investment Value to Par and Peninsula (the "Equity Participation"), less any shares of US Airways Group common stock previously issued to them pursuant to the Equity Participation. For purposes of the Amended Participation Agreements, "Additional Pre-Investment Value" means the amount equal to: (A) $15.00, multiplied by (B) (x) the number of shares of US Airways Group common stock that would have been issued in the alternative reorganization or business combination transaction had the investment been made at $15.00 per share minus (y) the number of shares of US Airways Group common stock issued in such transaction. A copy of each of the Amended Participation Agreements is attached hereto as Exhibits 10.3 and 10.4 and is incorporated herein by reference. The description of the Amended Participation Agreements is qualified in its entirety by reference to the full text of the Amended Participation Agreements. * * * FORWARD-LOOKING STATEMENTS Certain of the statements contained herein should be considered "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995.
