 Section 2.01 Issuance and Purchase of New Common Stock. 
  
 Upon the terms and subject to the conditions set forth in this Agreement,
and in reliance upon the representations and warranties hereinafter set forth, the Investor grants to the Company an option to require the Investor to purchase for an aggregate purchase price of one hundred twenty five million dollars ($125,000,000)
(the “Investment Price”), that number of shares of common stock of the reorganized Company (the “New Common Stock”) on a Fully Diluted Basis determined in accordance with Schedule 1 attached hereto; provided,
however, that in no event shall the New Common Stock issuable to the Investor on a Fully Diluted Basis as of the Effective Date represent less than 19.2308% of the total New Common Stock of the reorganized Company. Notwithstanding the
immediately preceding sentence, to the extent that Eastshore agrees to amend the Air Wisconsin DIP Agreement to provide for a reduction in its equity ownership in the Company on a Fully Diluted Basis below 19.2308% in the event that any Substantial
Investor makes an investment in the Company, the Investor will also agree to a comparable (on a pari passu basis with Eastshore and on terms and conditions no less favorable to the Investor as are accorded to Eastshore in connection with such
agreement) reduction in its equity ownership in the Company on a Fully Diluted Basis; provided, that in no event shall Investors’ equity ownership on a Fully Diluted Basis be reduced below 16.6666%. At the Closing, if the Company exercises the
option described above, the reorganized Company will issue, sell and deliver to the Investor, and the Investor will purchase from the reorganized Company, the New Common Stock in accordance with the first sentence of this Section 2.01. The foregoing
option shall be deemed terminated and cancelled if the Company shall not have given the Investor written notice at least sixty (60) days prior to the Effective Date of its exercise of the option (indicating the amount it will require Investor to
purchase) and such notice shall be irrevocable unless otherwise consented to by the Investor in its sole discretion. 
  
 Section 2.02 Slots Option. Subject to the terms and conditions hereof, the Investor hereby grants US Airways (and its successor under the Plan) the
Slots Option. 
  
 Section 2.03 Closing. (a) Subject to the
satisfaction or, if permissible, waiver of the conditions set forth in Sections 8.01 and 8.02 hereof, the Closing shall take place at the offices of Arnold & Porter LLP, 555 Twelfth Street, NW, Washington D.C. 20004, at 10:00 a.m., Washington
D.C. time, on the Effective Date or at such other time, date and place as the parties may agree (the date on which the Closing occurs, the “Closing Date”); provided that the parties shall use commercially reasonable efforts to have the
Closing take place on the Effective Date. 
  

 10 

 (b) At the Closing, (i) the reorganized Company shall deliver to the Investor certificates representing
the shares of Common Stock to be purchased by, and sold to, the Investor pursuant to Section 2.01 hereof (registered in the names and in the denominations designated by the Investor at least two Business Days prior to the Closing Date), together
with the other documents, certificates and opinions to be delivered pursuant to Section 8.01 hereof, and (ii) the Investor, in full payment for the shares of Common Stock to be purchased by, and sold to, the Investor pursuant to Section 2.01 hereof,
shall pay to the reorganized Company as provided in Section 2.01 hereof, an aggregate amount equal to (x) the Investment Price minus (y) any amounts due as of the Closing Date to the Investor pursuant to Section 10.01 hereof (such payment to
be made in immediately available funds by wire transfer to the account designated by the Company, or by such other means as may be agreed between the parties hereto), and shall deliver the certificate required pursuant to Section 8.02(a) hereof.

  
 Section 2.04 Terms of Additional Investments. If the
Company, the Operating Companies or any of their respective Affiliates provides to any Person (including, but not limited to, any other Substantial Investor) that commits to acquire any shares of New Common Stock or any other Equity Securities of
the reorganized Company in connection with the Plan, any terms relating to such acquisition more favorable than those applicable to the Investor pursuant to this Agreement, then, in each such case, the Company shall provide written notice to the
Investor of such more favorable terms (the “Notice”). Within ten (10) Business Days following receipt of the Notice, the Investor may by written notice to the Borrower elect to accept any of the more favorable terms to apply to the
Investor hereunder. If the Investor does not so elect within such ten (10) Business Day period, the Investor shall have waived its right to accept the more advantageous terms that were described in the Notice. Anything in this Section 2.04 to the
contrary notwithstanding, the election provided to the Investor herein shall not be applicable with respect to any distributions of New Common Stock, subscription rights, or securities exchangeable for or convertible into equity securities in the
reorganized Company to the extent that the distributions of such securities and rights are to any creditors, shareholders, management, or employees of the Company or of any of its Subsidiaries, or on account of the GECC Convertible Note, in

Section 6.09(b). The Initial Business Plan or the most recent Amended Business Plan delivered to and approved by the Investor in accordance with the terms hereof, is hereinafter referred to as the “Final Approved Business Plan”.

  
 (c) If at any time and from time to time on or prior to the
Effective Date, the Company proposes to offer any shares of New Common Stock or any other Equity Securities of the reorganized Company in connection with the Plan on terms different, in any material respect, than those contained in this Agreement,
the Company shall promptly, but in any event not less than five (5) Business Days prior to making an offer to sell such New Common Stock or Equity Securities to a third party, provide Investor with written notice of its intent to make such offer (an
“Alternative Equity Offer Notice”) describing in detail all of the material terms and conditions of such offer, including the proposed ancillary arrangements and closing contingencies relating thereto (an “Alternative Equity
Offer”). Delivery of an Alternative Equity Offer Notice by the Company shall constitute an irrevocable offer by the Company to the Investor to purchase the New Common Stock or Equity Securities on the terms and conditions of the Alternative
Equity Offer. The Investor shall have a period of five (5) Business Days from the date of receipt of such Alternative Equity Offer Notice to notify the Company in writing of its intention to accept the offer to purchase the New Common Stock or
Equity Securities on the terms and conditions of the Alternative Equity Offer and the failure to deliver such notice by the Investor shall be deemed a rejection thereof. If the Company fails to comply with this Section 6.09(c), it will lose certain
of its rights under the Jet Service Agreement (as described in Exhibit C, paragraph 3(g)) to terminate aircraft.

seeking entry of the Omnibus Order and the negotiation of final forms of the definitive Transaction Documents, none of the parties hereto (or their Affiliates) shall be bound or obligated by this Agreement or any of the schedules or exhibits
thereto.

 ADDITIONAL COVENANTS 
  
 Section 7.01 Financial and Other Information. From and after the date hereof, the Company shall (and shall cause each of the Operating Companies
to) afford to the Investor, its Affiliates and their respective Representatives, including qualified prospective lenders to the Investor that sign appropriate confidentiality agreements, access, upon reasonable notice and in such manner as will not
unreasonably interfere with the conduct of such companies’ respective businesses, to their respective facilities, properties, books, contracts, commitments, records (including information regarding any material pending or threatened legal
proceeding to which any of such companies is, or reasonably expects to be, a party and negotiations relating to any labor agreements or labor disputes involving the Company or any of its Subsidiaries), key personnel, officers, independent
accountants and legal counsel; provided, however, that the Company will not be required to provide access to employee personnel files if providing such files would be unreasonable or a violation of applicable Law. The Company shall use
its commercially reasonable efforts to cause its lessors of the Leased Aircraft to cooperate with the Investor, its Affiliates and their respective Representatives in connection with the Transactions. 
  
 Section 7.02 Publicity. Except as required by Law or by obligations
pursuant to any listing agreement with or requirement of any national securities exchange or national quotation system on which the Common Stock is listed, admitted to trading or quoted, neither the Company (nor any of its Affiliates) nor the
Investor (nor any of its Affiliates) shall, without the prior written consent of each other party hereto, which consent shall not be unreasonably withheld or delayed, make any public announcement or issue any press release with respect to the
transactions contemplated by this Agreement. Prior to making any public disclosure required by applicable Law or pursuant to any listing agreement with or requirement of any relevant national exchange or national quotation system, the disclosing
party shall consult with the other parties hereto, to the extent feasible, as to the content and timing of such public announcement or press release. To the extent either party is required to file this Agreement or any Transaction Document with the
SEC or any other Governmental Authority (including the Bankruptcy Court), the parties shall consult with each other concerning information for which confidential treatment will be requested.

After the consummation of the Plan, the reorganized Company shall use its commercially reasonable efforts to cause (i) the listing or quotation of the New Common Stock on a national stock exchange or the NASDAQ National Market System as soon as
reasonably practicable, but in all events not later than 180 days after the consummation of the Plan, and (ii) a registration statement to be filed and declared effective upon the expiration of 12 months from the consummation of the Plan, and shall
keep such registration statement effective for two (2) years thereafter. 
  
 Section 7.04 Restrictions on Sale. The Investor agrees not to sell any New Common Stock prior to the earlier of the first anniversary of the Effective Date and the date that is six (6) months after the date on

 21 

 during any six (6) month period the Investor shall not sell, transfer or dispose of more than twenty-five percent (25%)
of the New Common Stock issued to the Investor in connection with the consummation of the Plan, provided that, notwithstanding any of the foregoing, the Investor may transfer any of its New Common Stock to any of its Affiliates, so long as such
Affiliate agrees to be bound by the terms of this Agreement and, if requested by the Company, Investor’s counsel provides the Company with an opinion that such transfer is exempt from the registration requirements of the Securities Act. In
addition, the Investor agrees not to sell, transfer or dispose of the New Common Stock in any manner that will, in one or more transactions involving the Investor, cause a change of control event for purposes of any of the Collective Bargaining
Agreements in effect on the date hereof or as may be modified after the date hereof in a manner that does not adversely affect the Investor for purposes of this restriction. 
  
 Section 7.05 Additional Jet Service Aircraft. The Investor hereby grants US Airways the option, if the Closing

will not be required to cure any default under the Original Jet Service Agreement in connection with the assumption of the Existing Jet Service Agreement.

the Company or their respective Affiliates to consummate the Transactions; (iii) no Governmental Authority shall have instituted any legal proceeding that seeks to restrain, enjoin, prevent, delay, prohibit or otherwise make illegal the performance

attached or delivered pursuant hereto (including, without limitation, the other Transaction Documents) set forth the entire agreement between the parties hereto with respect to the transactions contemplated by this Agreement. Any provision of this
Agreement may only be amended, modified or supplemented in whole or in part at any time by an agreement in writing among the parties hereto executed in the same manner as this Agreement. No failure on the part of any party to exercise, and no delay
in exercising, any right shall operate as waiver thereof, nor shall any single or partial exercise by either party of any right preclude any other or future exercise thereof or the exercise of any other right. No investigation by a party hereto of

 EXHIBIT A-1 
 SLOTS OPTION 
  
 The completion of
the transactions contemplated in this Exhibit A-1 is subject to the negotiation and execution of definitive documentation incorporating the terms set forth in this Exhibit A-1 and customary representations, warranties, covenants and conditions for a
transaction of this type, as well as events of default and remedies in respect thereof. The parties will use reasonable commercial efforts to complete such definitive documents prior to the entry of the Omnibus Order. The execution of the definitive
documentation for certain aspects of the transactions described herein will require the consent and approval of the ATSB Lender Parties. 
  
 1. Slot/Gate Option. At US Airways’ discretion, upon thirty (30) days’ prior written notice to the Investor and prior to the
Effective Date of the Plan, but in any event no later than December 31, 2005, US Airways may exercise its option to sell to Investor and license from Investor the right to use certain Slots at LGA and DCA which Investor will commit to acquire as
follows (the “Slots Option”) and the Company will provide the Investor with an option to acquire the Gates under certain specified conditions as specified below: 
  
 (a) Purchase of Slots. Investor will purchase one hundred thirteen (113) Unrestricted Commuter Slots at DCA
and twenty-four (24) Unrestricted Commuter Slots at LGA (“Slots”) for an aggregate purchase price of $51.64 million, less the reasonable legal fees and expenses of the Investor incurred in connection with the purchase and license back of
the Slots. The purchase of the Slots shall be subject to and concurrent with the consummation of the purchase of the Currently Owned Aircraft under the Republic Aircraft Transaction. Schedule 1 to this Exhibit A-1 contains a description of the
Slots. 
  
 (b) Sale/License. Investor will enter
into a license agreement with US Airways (the “Slot License”) to license US Airways’ right to use the Slots for a period equal to the later term of (a) the Existing Jet Service Agreement or (b) such other jet service agreement as may
be entered into between Republic or its Affiliate and US Airways relating to the EMB-170 and EMB-190 aircraft contemplated to be operated pursuant to a jet service agreement in the event the Republic Aircraft Transaction or the Additional Jet
Service Aircraft transactions are consummated (the “New Jet Service Agreement”, and together with the Existing Jet Service Agreement, the “Jet Service Agreements”)1. The DCA Slots will be licensed at an annual license fee in an amount equal to [REDACTED] of the purchase price, payable monthly in arrears. The LGA Slots will
be licensed at an annual license fee, payable monthly in arrears, in an amount equal to the level monthly payments sufficient to fully amortize the purchase price over the earlier of the expiration of the term of the New Jet Service Agreement or
that date on which the Slots or their functional equivalent expire at an annual interest rate of [REDACTED]. 

	1	The Existing Jet Service Agreement and the New Jet Service Agreement will have identical terms, except as otherwise contemplated on Exhibit D hereto and shall be
cross-defaulted. 

  

 34 

 (c) Termination. In the event that (i) US Airways consummates a chapter 11 plan of
reorganization in the Cases, including a liquidating chapter 11 plan, and neither it nor its successor under the plan continues to operate as an airline, and substantially all of US Airways’ flight operations are, therefore, discontinued, or
(ii) US Airways’ Case is dismissed or converted to a case under chapter 7 of the Bankruptcy Code, or US Airways is otherwise liquidated, and as a result of such dismissal, conversion or liquidation, substantially all of US Airways’ flight
operations are discontinued, US Airways may reject or terminate either or both of the Jet Service Agreements by providing ten (10) business days prior written notice to Chautauqua, Republic or the applicable Republic Affiliate, as the case may be,
and US Airways shall be deemed to have breached such Jet Service Agreement(s) as of the effective date of the applicable notice (the “Breach Date”) and Chautauqua, Republic or the applicable Republic Affiliate, as the case may be, shall
have, subject to objection as provided below: (x) administrative expense claims under sections 503 and 507 of the Bankruptcy Code for any obligations arising prior to the Breach Date with respect to the applicable Jet Service Agreement and (y)
general unsecured pre–petition claims under section 502(g) of the Bankruptcy Code for future damages resulting from such rejection or termination and for obligations that arise after the Breach Date with respect to the applicable Jet Service
Agreement. In each case the amount of the respective claims shall be subject to the ordinary claims process, including the right of parties in interest to object to the amount (but only the amount) of such claims. In the event that US Airways
materially defaults on either of the Jet Service Agreements or the Owned Aircraft Leaseback or the Jet Service Agreements otherwise terminate, other than in connection with a material breach by Chautauqua/Republic thereunder, the Slot License will
terminate. A default under the Slot License shall constitute a default under the Jet Service Agreements giving rise to the Investors’ right to terminate either or both Jet Service Agreements. 
  
 (d) Repurchase Option. Provided that US Airways is not in
material default under the Jet Service Agreements, the Owned Aircraft Leaseback or the Slot License, US Airways will have the right to repurchase all, but not less than all, of the DCA Slots (by acquiring the equity of the Special Purpose Trust
referred to below) at a price equal to the Investor’s purchase price and the LGA Slots at a price equal to the greater of the unamortized amount of the purchase price for such Slots and $1 (the “Repurchase Option”) (a) at any time
after US Airways’ emergence from the Chapter 11 Case and prior to the expiration of the term of the Slot License, or (b) upon the termination of either of the Jet Service Agreements by US Airways as a result of a material breach by
Chautauqua/Republic. As a condition precedent to the granting of the Repurchase Option, the Company shall, among other things, grant to the Investor (i.e., the buyer of the Slots) a perfected security interest in and first lien on the Repurchase
Option and all proceeds thereof (including, without limitation, the assets acquired upon the exercise of the Repurchase Option) to secure the Company’s obligations under the Jet Service Agreements. Upon exercise by the Company of the Repurchase
Option, (i) the Slots shall be transferred to a bankruptcy remote, special purpose trust (the “Special Purpose Trust”) whose sole beneficial owner will initially be the Investor, who shall immediately transfer such equity to the Company,
(ii) the notice of exercise of such option shall include a paragraph in which US Airways expressly grants in favor of Investor a perfected, first priority security interest in the equity of the Special Purpose Trust, (iii) such interest shall be
transferred subject to the retention by the Investor of a perfected, first priority security interest in such equity, (iv) such equity will constitute proceeds of and shall be subject to a perfected security interest and first lien in favor of the
Investor and (v) the Company shall simultaneously cause the Special Purpose 
  

 - 35 - 

 Trust to grant to the Investor a perfected, first priority security interest in the Slots. Provided that the Company or
any of its Subsidiaries is not in default under either of the Jet Service Agreements, the Investment Agreement or any other document contemplated therein, at the expiration of two (2) years following exercise of the Repurchase Option, the liens and
security interests shall terminate unless on or prior to such date the Company becomes subject to a bankruptcy proceeding, in which event the two year period shall be extended for a period equal to the period it takes to obtain a final order either
dismissing or closing such proceeding. 
  
 (e) Option to
Acquire Gates. Investor will be granted options to acquire (through sublease, assignment or otherwise) US Airways’ rights to the Gates, subject to any restrictions contained in the existing underlying leases and to the receipt of all
necessary airport and regulatory approvals and third party consents (the “Gates Option”). 
  
 (i) Option Exercise. The Gates Option shall only be exercisable in the event that US Airways defaults under the Slot License or is in
default under either of the Jet Service Agreements and such default is not cured by US Airways within thirty (30) days of receipt of written notice of default by Investor; provided that Investor must exercise the Gates Option within thirty (30) days
after the expiration of such cure period. 
  
 (ii)
Terms. The exercise price for the Gates Option shall be an amount equal to the fair market value of US Airways’ rights to the Gates determined on a basis as if no Gates Option existed, to be agreed upon at the time of exercise, or
in the event the parties are unable to agree, to be determined by mandatory binding baseball arbitration.

 EXHIBIT B 
 REPUBLIC AIRCRAFT TRANSACTION 
  
 The completion of the transactions contemplated in this Exhibit B is subject to the negotiation and execution of definitive documentation incorporating the terms set forth in this Exhibit B and customary representations, warranties,
covenants and conditions for a transaction of this type, as well as events of default and remedies in respect thereof. The parties will use reasonable commercial efforts to complete such definitive documents prior to the entry of the Omnibus Order.
The execution of the definitive documentation for certain aspects of the transactions described herein will require the consent and approval of the ATSB Lender Parties. 
  
 2. Acquisition of EMB-170 Aircraft. 
  
 (a) Slots Option Exercised. In the event that US Airways exercises and consummates the Slots Option, Republic
will at the same time purchase the ten (10) EMB-170 aircraft currently owned by US Airways (the “Currently Owned Aircraft”) and, at US Airways’ option, and so long as US Airways has arranged for 100% lease financing to have been made
available to Republic at such time and on terms reasonably acceptable to Republic, the three (3) EMB-170 aircraft currently committed to be delivered by Embraer (the “EMB Committed Aircraft” and, in the event the Company acquires the EMB
Committed Aircraft prior to the purchase of the Currently Owned Aircraft by Republic, then together with the Currently Owned Aircraft, the “Owned Aircraft”; the EMB Committed Aircraft, together with any Additional Jet Service Aircraft
described in Exhibit E, are the “Growth Aircraft”) and, subject to Republic’s satisfaction with the terms and conditions thereof and arrangements with respect thereto mutually agreed upon by Investor, US Airways and GECC, assume the
leases for the fifteen (15) EMB-170 aircraft that are currently leased by US Airways (the “Leased Aircraft”), and, subject to terms mutually agreed upon among Investor, US Airways and Embraer, Investor shall further assume US Airways
obligations to purchase additional aircraft from Embraer (the “Aircraft Orders”). Republic acknowledges that it has no right to any pre-delivery deposits posted with Embraer on account of the EMB Committed Aircraft. 
  
 (b) Slots Option Not Exercised. If the Slots Option has not
been exercised, the Investor shall have a one-time option, exercisable by written notice to the Company at any time during the thirty (30) day period commencing upon either the Effective Date or the date of termination of the Investment Agreement
(unless such termination is pursuant to Section 9.01(c) or (d) thereof), to purchase the Owned Aircraft and to assume the leases of the Leased Aircraft under the terms of this Exhibit B. If so exercised, the Company shall cause its Affiliates to
enter into the Republic Aircraft Transaction (subject to the applicable conditions thereto) within thirty (30) days of delivery of such notification (or such other date as the Investor and the Company shall agree in writing). 
  
 (c) Purchase Price/Debt Assumption. The purchase price for the
Owned Aircraft shall be a price equal to the fair market value of US Airways’ equity in such aircraft, which shall be $44.0 million for the Currently Owned Aircraft, (i) less any accrued maintenance costs, which shall be set at a rate of
[REDACTED], (ii) plus any pay down of debt on account of 
  

 42 

 the Currently Owned Aircraft from the date of the Investment Agreement to Closing, (iii) less assumed depreciation of
[REDACTED], commencing [REDACTED] and (iv) less any loss discovered through inspection of the aircraft that is not covered by effective warranty. In connection with such purchase Republic will assume all current debt obligations associated with the
Owned Aircraft, currently in the approximate amount of $169.4 million, subject to assignment to and assumption by Investor of such outstanding debt and Investor being satisfied with the terms and conditions of such debt and arrangements with respect
thereto mutually agreed upon by Investor, US Airways and Embraer, and US Airways will assign to Republic any remaining support package made available by Embraer in respect of such aircraft. The purchase of the Owned Aircraft is subject to the
inspection of such aircraft by the Investor. 
  
 (d) Lease
of Owned Aircraft. Republic will initially lease the Owned Aircraft back to US Airways at a monthly rate, payable monthly in advance and determined in accordance with the Lease Formula (as defined in Exhibit F), for a period beginning on the
purchase date and continuing until the successful completion of transition of each aircraft to the Republic certificate (the “Owned Aircraft Leaseback”). In addition to the monthly rates set forth in the Lease Formula, the monthly lease
payments shall include maintenance reserves, determined based on a rate of [REDACTED], assuming [REDACTED], payable bi-weekly in advance. At the inception of each lease, US Airways shall pay Republic a deposit of two months’ lease payments.
Concurrent with transferring each aircraft to Republic’s certificate, Republic will return the two months’ security deposit, any portion of the rent paid in advance by US Airways for such aircraft pertaining to a monthly period not fully
elapsed and any excess maintenance reserves. Republic will provide the Company with a monthly reconciliation of maintenance reserves compared with actual flight hours within fifteen (15) days following the end of each month and the next lease
payment will be adjusted, up or down, to reflect the actual flight hours. 
  
 (e) Leased Aircraft. US Airways will assign its rights and Republic will assume all of US Airways’ obligations under the current lease agreements covering the Leased Aircraft, subject to US Airways
paying any cure costs related thereto and to Republic’s satisfaction with the terms and conditions of such lease agreements; such assignment and assumption to occur as the leased aircraft are transitioned to the Republic Certificate as provided
below and begin operation under the New Jet Service Agreement. To the extent that US Airways has made payments in the form of security deposits or excess rent payments to or for the benefit of a lessor which have resulted in payments in excess of
the cumulative amount of GAAP rent (defined as the average periodic rental payments due under the applicable lease) owing to such lessor, then such excess amount shall be recaptured by US Airways through lower payments under the Jet Service
Agreement in a manner consistent with recognizing that US Airways should benefit by such higher initial rent payments. Republic and US Airways agree to negotiate in good faith to ensure that US Airways obtains the full benefit of such overpayments
during the term of the Jet Service Agreement and so long as US Airways is not in material breach of any payment obligation under the Jet Service Agreement. Republic’s obligation to assume any remaining leases of Leased Aircraft to be assumed
shall terminate upon (i) the material breach by the Company of any of the Transaction Documents or (ii) the termination of the Investment Agreement (other than a termination under Section 9.01(c) or (d) thereof). 
  

 - 43 - 

 (f) Transition of Owned and Leased Aircraft. Beginning the later of [REDACTED] and
sixty (60) days after Republic’s acquisition of the Owned Aircraft and Leased Aircraft, Republic will use commercially reasonable efforts to transition the Owned Aircraft and Leased Aircraft to the Republic Certificate at a rate of three (3)
aircraft per month; provided that the Currently Owned Aircraft shall be transitioned first and, if the EMB Committed Aircraft are acquired by Republic, the EMB Committed Aircraft shall be the first of the Leased Aircraft to be transitioned. Without
limiting the foregoing, the parties will agree upon a schedule for the transition of the Owned Aircraft and Leased Aircraft, including outside dates by which the leases must be assigned to and assumed by Republic. In the event that the Company
leases the EMB Committed Aircraft, the parties will agree to a schedule for the assumption of such leases. 
  
 (g) Operation of Owned Aircraft and Leased Aircraft. Upon transition of the Owned Aircraft and Leased Aircraft as described above, Republic
will operate the Owned Aircraft and Leased Aircraft as US Airways Express under the terms of the New Jet Service Agreement, as amended in accordance with the terms of Exhibit D. 
  
 (h) Preferential Hiring. Republic will comply with the terms of Letter of Agreement #91 to the US Airways
– ALPA Collective Bargaining Agreement with respect to the flight crews currently employed by US Airways’ EMB-170 Division (“Mid-Atlantic”), and will offer preferential hiring to any flight attendants and mechanics currently
employed at Mid-Atlantic. Furthermore Republic will comply with such Letter of Agreement #91 associated with any additional aircraft. 
  
 (i) Maintenance Facility. In the event the Investor acquires the Owned Aircraft and the Leased Aircraft, Republic agrees to relocate its
EMB-170/-190 heavy overhaul maintenance facility to a location specified by US Airways that is east of the Mississippi River and is consistent with Republic maintaining low operating costs in order to enhance US Airways’ ability to attract
additional financial support, provided that Republic receives local government economic and other support relative to the establishment of such facility reasonably satisfactory to the Investor. 
  
 (j) Purchase of Other Assets. In the event the Investor
acquires the Owned Aircraft and the Leased Aircraft, Investor will purchase, free and clear of all liens, a flight simulator and a cabin door trainer (together with all licenses and agreements related to the operation thereof) for an aggregate
purchase price equal to the fair market value thereof of approximately $9.5 million, and will also purchase certain spare parts and tooling equipment at an aggregate purchase price equal to the fair market value thereof and not to exceed $5.0
million. Any such purchase shall be subject to inspection by Investor. 
  
 (k) Fees of Aircraft Advisor. In the event Investor acquires any Growth Aircraft, Republic agrees to undertake any obligations owing to US Airways’ aircraft advisor with respect to fees payable in connection with
financing agreements with respect to Growth Aircraft. Any such costs shall be capitalized with the cost of the aircraft and passed through as a cost to US Airways under the New Jet Service Agreement and will be incremental to the lease rates
calculated in accordance with the Lease Formula on Exhibit F.

 EXHIBIT C 
 AMENDMENTS TO ORIGINAL JET SERVICE AGREEMENT 
  
 The Original Jet Service Agreement shall be amended and restated to reflect the following changes. Except as set forth below, the substantive terms and conditions of the Original Jet Service Agreement shall not change
(although the form of such agreement will be modified). 
  
 (1) Existing Jet
Service Agreement Costs (as contained in the Original Jet Service Agreement, with the following modifications): 
  
 [REDACTED] 
  
 (2) Comparable Terms to Air Wisconsin. In the Existing Jet Service Agreement, US Airways will represent to Chautaqua that the costs specified in Section 1 of this Exhibit C, taken as a whole, are not
materially different in costs to US Airways, on an average stage length of approximately [REDACTED] and approximately a [REDACTED], to the terms under the Air Wisconsin Airline Corporation Jet Service Agreement as approved by the Bankruptcy Court on
February 28, 2005. 
  
 (3) Term. The term of the Original Jet
Service Agreement shall be modified as follows: 
  
 (a) In the
event that US Airways does not exercise the Slots Option, at US Airways’ option, US Airways shall have the one-time right to terminate up to five (5) of the ERJ-145 aircraft flown under the Existing Jet Service Agreement, subject to 60
days’ written notice to Chautauqua prior to the termination of the first of such aircraft. US Airways may exercise this right by providing notice prior to the Effective Date (after which date such right shall expire), which notice shall specify
the termination dates for such aircraft. 
  
 (b) Subject to
Section 3(e) below and upon prior written notice delivered not later than the Effective Date, in the event US Airways exercises and consummates the Slots Option, at US Airways’ option, US Airways shall have the one-time right to terminate five
(5) ERJ-145 aircraft flown under the Existing Jet Service Agreement as follows: one (1) ERJ-145 aircraft may be terminated on the date that is the later of (x) the date each fifth Owned Aircraft or Leased Aircraft, collectively, is placed into
service under the New Jet Service Agreement or (y) the dates for such termination rights set forth in Schedule I to this Exhibit C. 
  
 (c) Subject to Section 3(e) below, in the event US Airways exercises its option to cause Republic to acquire the Growth Aircraft (and the parties reach
agreement on the delivery dates and other terms and conditions with respect to such Growth Aircraft), US Airways shall have the right to terminate two (2) ERJ-145 aircraft flown under the Existing Jet Service Agreement for every five (5) Growth
Aircraft 
  

 - 45 - 

 flown under the New Jet Service Agreement as follows: two (2) ERJ-145 aircraft may be terminated on the
date that is the later of (x) the date each fifth such Growth Aircraft is placed into service under the New Jet Service Agreement or (y) the dates for such termination rights set forth in Schedule I to this Exhibit C. 
  
 (d) At any time and from time to time during the period in which US Airways
has the right to terminate ERJ-145 aircraft flown under the Existing Jet Service Agreement under any of Section 3(a), Section 3(b), Section 3(c) or Section 3(g) of this Exhibit C, Chautauqua shall have the right to deliver to US Airways written
notice (a “Preliminary Chautauqua Termination Notice”) that it desires to terminate up to an aggregate number of ERJ-145 aircraft flown under the Existing Jet Service Agreement that does not exceed fifteen (15) less any such
aircraft that have been previously terminated under Section 3(a), Section 3(b), Section 3(c) or Section 3(g) or this Section 3(d). Within 10 Business Days of receipt of a Preliminary Chautauqua Termination Notice, US Airways shall have the right to
notify Chautauqua as to whether it accepts or rejects (which acceptance or rejection may be as to all, some or none of the aircraft designated for termination by Chautauqua in such Preliminary Chautauqua Termination Notice) Chautauqua’s
Preliminary Chautauqua Termination Notice. The failure of US Airways to deliver such notification within such 10 Business Day period shall be deemed an acceptance of Chautauqua’s Preliminary Chautauqua Termination Notice. In the event US
Airways gives timely written notice to Chautauqua that it rejects Chautauqua’s Preliminary Chautauqua Termination Notice as to any or all of aircraft designated for termination, then the total number of aircraft that US Airways may terminate
under Section 3(a), 3(b), 3(c) or 3(g) shall be reduced by the number of aircraft so rejected by US Airways (it being understood and agreed that the aircraft shall be reduced in the chronological order in which they are then eligible for termination
under any of Section 3(a), 3(b), 3(c) or 3(g)). In the event US Airways accepts (or is deemed to accept) Chautauqua’s written notice, then Chautauqua shall have the right to give US Airways written notice (a “Final Chautauqua
Termination Notice”), within not more than sixty (60) days from the acceptance or deemed acceptance of the Preliminary Chautauqua Termination Notice, as to the date(s) on which some or all of the aircraft designated for termination in the
Preliminary Chautauqua Termination Notice will be removed from service under the Existing Jet Service Agreement, and the number of such aircraft to be removed on each such date, provided, however, that the removal of the first of such aircraft shall
commence no earlier than sixty (60) days, and no later than one hundred twenty (120) days, from the date of the Final Chautauqua Termination Notice, and the Existing Jet Service Agreement shall terminate as to each such aircraft on the date
specified in the Final Chautauqua Termination Notice. If Chautauqua does not give such Final Chautauqua Termination Notice within the required sixty (60) day period, then Chautauqua may not terminate the aircraft subject to the Preliminary
Chautauqua Termination Notice unless it again complies with the provisions of this Section 3(d). In the event that Chautauqua exercises its right under this Section 3(d), US Airways will not be required to terminate more than two (2) aircraft in any
thirty (30) day period. 
  

 - 46 - 

 (e) US Airways shall not have the right to terminate ERJ-145 aircraft as provided for in Sections 3(b)
and 3(c) of this Exhibit C in the event and for so long as US Airways is then flying regional jet aircraft directly or indirectly owned or operated by any regional jet provider flying as “US Airways Express” other than (a) Air Wisconsin
Airline Corporation, under the Air Wisconsin Jet Service Agreement (up to a maximum of 70 aircraft) or (b) any other such regional jet provider flying 50-seater aircraft that makes an equity investment in connection with the Plan in the Company
which equates to at least [REDACTED] in each aircraft in such regional jet provider’s fleet then flying for US Airways; provided, however, that with respect any such other regional jet provider, at such time as US Airways has reduced the size
of such other regional jet provider’s 50-seater fleet being operated by US Airways to a point where such other regional jet provider’s investment in US Airways equates to at least [REDACTED] per aircraft, then US Airways may thereafter
terminate ERJ-145 aircraft of Chautauqua under the Existing Jet Service Agreement pursuant to Sections (3)(b) and (3)(c) of this Exhibit C in proportion to the rate at which US Airways terminates the remaining 50-seater fleet of such other regional
jet provider. 
  
 (f) The term of the Existing Jet Service
Agreement with respect to ERJ-145 aircraft not terminated pursuant to Sections 3(a) or 3(b) of this Exhibit C shall be March 1, 2013 (i.e., a one-year extension). 
  
 (g) If (i) the Company exercises its option to require the Investor to purchase New Common Stock under Section 2.01 of the
Investment Agreement and, in connection therewith, exercises the Slot Option, to be consummated upon the Investor’s purchase of the New Common Stock, (ii) the Investor has not consummated the purchase of New Common Stock other than as a result
of a failure of a condition to be satisfied or waived by the Investor under Section 8.01 (other than the condition that the Investor shall have approved the Initial Business Plan and any Amended Business Plan, or the condition that the Company shall
have consummated the Slot Option, to the extent that such failure to consummate the Slot Option results from the Investor’s election not to consummate the purchase of the New Common Stock), (iii) the sale of New Common Stock is completed with a
third party investor in connection with the consummation of the Plan on terms and conditions substantially identical, in all material respects, or on terms more favorable to the investor to those contained in the Investment Agreement and, if more
favorable, that were offered to the Investor under Section 6.09(c) of the Agreement and that the Investor declined to accept, and (iv) the Slot Option is not and has not been consummated with the Investor, then US Airways shall have the one-time
right to terminate up to ten (10) additional aircraft flown under the Existing Jet Service Agreement, subject to six (6) month’s prior written notice to Chautauqua, which notice shall specify the number of aircraft to be terminated, and upon US
Airways’ exercise of such aircraft termination right, US Airways shall have no further right to exercise or consummate the Slot Option. 
  
 (h) Notwithstanding anything in Sections 3(a) through (g) (or Schedule I to this Exhibit C) to the contrary, (i) in no event may US Airways terminate, in
the 
  

 - 47 - 

 aggregate, more than two (2) aircraft in any thirty (30) day period and (ii) Republic Airways will have
the right to designate the specific aircraft to be terminated. 
  
 (4)
Treatment of Claims. In the event that (i) US Airways consummates a chapter 11 plan of reorganization in the Cases, including a liquidating chapter 11 plan, and neither it nor its successor under the plan continues to operate as an
airline, and substantially all of US Airways’ flight operations are, therefore, discontinued, or (ii) US Airways’ Case is dismissed or converted to a case under chapter 7 of the Bankruptcy Code, or US Airways is otherwise liquidated, and
as a result of such dismissal, conversion or liquidation, substantially all of US Airways’ flight operations are discontinued, US Airways may reject or terminate either or both of the Jet Service Agreements by providing ten (10) business days
prior written notice to Chautauqua, Republic or the applicable Republic Affiliate, as the case may be, and US Airways shall be deemed to have breached such Jet Service Agreement(s) as of the effective date of the applicable notice (the “Breach
Date”) and Chautauqua, Republic or the applicable Republic Affiliate, as the case may be, shall have, subject to objection as provided below: (x) administrative expense claims under sections 503 and 507 of the Bankruptcy Code for any
obligations arising prior to the Breach Date with respect to the applicable Jet Service Agreement and (y) general unsecured pre–petition claims under section 502(g) of the Bankruptcy Code for future damages resulting from such rejection or
termination and for obligations that arise after the Breach Date with respect to the applicable Jet Service Agreement.

emergence from the prior bankruptcy of the Company, a number of employees complained to several regional offices of the SEC that the method of distribution and notification of vesting employed by the Company resulted in giving unfair advantage to
some employees and perhaps management over others. In each instance, the SEC office in question forwarded to the Company and inquiry requesting an explanation. The Company responded to each request with a full explanation of the method of
distribution and vesting provisions. The Company did not receive any further communication from the SEC regarding these complaints. These inquiries arrived and were responded to during the second half of 2003.

conditioned upon the approval of the United States Bankruptcy Court for the Eastern District of Virginia (the “Court”) in the pending bankruptcy proceedings of US Airways, Inc., et al, as debtors (Case No. 04-13819) (“the Chapter 11
Case”). A motion for such approval shall be submitted by the Buyer as soon as practicable following the execution hereof and in any event within the period required in order that such motion may be heard at the Omnibus Hearing currently
scheduled for January 27, 2005. The Buyer shall, in addition, use commercially reasonable efforts to permit this Amendment and any related documents to be filed in redacted form in a manner satisfactory to the parties and consistent with previously
filed redacted documents. 
  

	3.	EFFECT OF AMENDMENT 

  
 Subject to receipt of Court approval, as required by Paragraph 2 above, the provisions of this Amendment shall constitute a valid amendment to the
Agreement and the Agreement will be deemed to be amended to the extent herein provided. This Amendment supersedes any previous understandings, commitments, or representations whatsoever, whether oral or written, related to the subject matter of this
Amendment. 
  
 Both parties agree that this Amendment will
constitute an integral, nonseverable part of the Agreement, and that this Amendment will be governed by the provisions of the Agreement, except that if the Agreement and this Amendment have specific provisions that are inconsistent, the specific
provisions contained in this Amendment will govern. 
  
 Both
parties agree that neither this Amendment nor the approval thereof, as provided in Paragraph 2 above, shall constitute an assumption of the Agreement or the Amendment under section 365 (a) of the Bankruptcy Code or otherwise in the Buyer’s
pending bankruptcy proceedings, and nothing contained herein shall be construed to constitute such an assumption, and the Buyer reserves all of its rights in such regard. 
  

	4.	GOVERNING LAW 

  
 THIS AMENDMENT WILL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
THE PERFORMANCE OF THIS AMENDMENT WILL BE DETERMINED ALSO IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK. THE PARTIES HEREBY
ALSO AGREE THAT THE UNITED NATIONS CONVENTION ON THE INTERNATIONAL SALE
OF GOODS WILL NOT APPLY TO THIS TRANSACTION.

 In addition to the confidentiality provisions of Clause 22.4 of the Agreement, the Buyer and the Seller agree that the Buyer may disclose the terms and
conditions of this Amendment to the parties to that ATSB loan agreement dated as of March 31, 2003, as amended, the Unsecured Creditors Committee in the Chapter 11 Case, any prospective lender to and/or equity investor in Buyer and their respective
financial advisors and legal counsel; provided, however, that such parties agree to hold the terms and conditions of this Amendment confidential. 
  

	6.	COUNTERPARTS 

  
 This Amendment may be executed by the parties hereto in separate counterparts, each of which when so executed and delivered will be an original, but all
such counterparts will together constitute but one and the same instrument. 

 If the foregoing correctly sets forth our understanding, please execute this Amendment in the space
provided below, whereupon, as of the date first above written, this Amendment will constitute part of the Agreement.
