Re:  Master Memorandum of Understanding ("Master MOU")among US Airways, Inc.
     (including, as the context may require, as reorganized pursuant to th
     Bankruptcy Code, "US Airways"), US Airways Group, Inc. (including, as the
     context may require, as reorganized pursuant to the Bankruptcy Code,
     "Group"), and General Electric Capital Corporation, acting through its
     agent GE Capital Aviation Services, Inc. ("GECC"; and together with GE
     Capital Aviation Services, Inc. "GECAS", GE Engine Services, Inc. "GE
     Engine Services" and General Electric Company, GE Transportation Component
     "GEAE" and their respective affiliates, the "GE Entities")

Gentlemen/Ladies:

This Master MOU, when countersigned by the respective parties, shall set forth
our understanding with respect to a restructuring of the indebtedness and
obligations of US Airways and Group to the GE Entities, which understanding was
reached in separate negotiations with each of such respective parties in
connection with the related matters contained herein.
<PAGE>
In conjunction with the bankruptcy proceedings of Group and certain of its
subsidiaries (including US Airways) under Chapter 11, Title 11 of the United
States Code (the "Chapter 11 Case") commenced on September 12, 2004 (the
"Petition Date") in the United States Bankruptcy Court for the Eastern District
of Virginia, Alexandria Division (the "Bankruptcy Court"), US Airways wishes to
obtain and GECAS is willing to provide (both during the Chapter 11 Case and upon
emergence pursuant to a plan of reorganization ("Plan of Reorganization")
confirmed by the Bankruptcy Court) the following: (i) certain lease
modifications with respect to certain GECC aircraft leased to US Airways as
described in Exhibit A; (ii) certain lease and other arrangements in respect of
future regional jet acquisitions by US Airways (the "Regional Jet Lease
Transactions") as described in Exhibit B; (iii) certain sale-leaseback
transactions as described in Exhibit C; (iv) certain modifications to the
financing evidenced by the Credit Agreement dated as of November 16, 2001 among
US Airways, as Borrower, GECC, as Lender and Group, as Guarantor (as amended,
supplemented and modified, the "2001 Facility") and the Exit Liquidity Facility
Agreement dated as of March 31, 2003 among US Airways, as Borrower, GECC, as
Lender and Group, as Guarantor (as supplemented and modified, the "2003
Liquidity Facility") as described in Exhibit D; (v) a new bridge financing
facility as further described in Exhibit E (the "Bridge Facility"); and (vi)
waiver of registration penalties for the [REDACTED] EETC as described in Exhibit
F. In consideration of the foregoing, US Airways has agreed to issue certain
Convertible Notes to a GE Entity upon emergence from the Chapter 11 Case, the
terms of which are described in Exhibit G.

In addition, US Airways wishes to obtain certain modifications with respect to
certain of its contracts with GE Engine Services and GEAE, and GE Engine
Services and GEAE are willing to modify such provisions of such contracts with
US Airways, as further described in Exhibit H.

Each of these transactions and modifications is to occur pursuant to the terms
and conditions set forth in the following applicable term sheets attached as
Exhibits A through H (each, a "Term Sheet" and, collectively, the "Term
Sheets"). Certain of the transactions and modifications described in the Term
Sheets are scheduled to take effect upon judicial approval of the Master MOU no
later than December 17, 2004 or described in the attached term sheets as a Phase
I Transaction (the "Phase I Transactions"); others are scheduled to take effect
on January 18, 2004 or described in the attached term sheets as a Phase II
Transaction (the "Phase II Transactions"); and others are scheduled to take
effect upon US Airways' exit from bankruptcy or described in the attached term
sheets as an Exit Transaction (the "Exit Transactions" and, together with the
Phase I Transactions and the Phase II Transactions, the "Restructuring
Transactions").

     Exhibit A: Aircraft Lease Term Sheet

     Exhibit B: Regional Jet Lease Transactions Term Sheet

                                        2
<PAGE>
     Exhibit C: Sale-Leaseback Term Sheet

     Exhibit D: Existing Facilities Term Sheet

     Exhibit E: Bridge Facility Term Sheet

     Exhibit F: [REDACTED] EETC Term Sheet

     Exhibit G: Convertible Note Term Sheet

     Exhibit H: GEAE Restructuring Term Sheet

The parties further acknowledge and agree that (i) the Restructuring
Transactions contemplated in this Master MOU are comprised of several separate
interrelated transactions (each of which is individually described in its
respective Term Sheet), and (ii) each Phase I Transaction and Phase II
Transaction is expressly conditioned upon the consummation of every other Phase
I Transaction and Phase II Transaction. In no event shall any Term Sheet be
viewed as a stand-alone transaction. Accordingly, each of the transactions and
modifications contemplated by the Term Sheets must be evidenced by executed
definitive agreements in order to effectuate the Restructuring Transactions.

Each of the Phase I Transactions, the Phase II Transactions and the Exit
Restructuring Transactions shall only take effect on the effective dates and, in
each case subject to the satisfaction of applicable conditions, for such
transactions (whether such conditions are provided for in the schedules to this
Master MOU or in the applicable Term Sheet).

Each and every obligation of US Airways and Group to a GE Entity, or to another
party where nonperformance of such obligation could impose an obligation on a GE
Entity, which may be created under this Master MOU and the Term Sheets (such
obligations of US Airways and Group, the "US Airways Restructuring Obligations")
will be (i) cross-defaulted to each and every US Airways Restructuring
Obligation unless such cross-default has specifically been waived by the
affected GE Entity or in the Term Sheets and (ii) cross-defaulted with the cash
collateral order in respect of the existing loan guaranteed by the Air
Transportation Stabilization Board (the "ATSB") in accordance with the Air
Carrier Guarantee Loan Program (the "ATSB Loan").

Each of the parties hereto acknowledges that this Master MOU and the related
Term Sheets contain commercially sensitive and proprietary information. Each of
the parties agrees to keep this information strictly confidential and agrees to
disclose it to no person other than: (A) their respective board(s) of directors;
(B) employees working on the subject matter of this Master MOU; (C) professional
advisors advising them concerning the subject matter of this Master MOU provided
that US Airways and such outside professional advisors execute a confidentiality
agreement in form and substance acceptable to GECC and GE Engine Services; (D)
the ATSB, provided that US Airways shall use commercially reasonable efforts to
prevent disclosure of such information under the Freedom of Information Act; (E)
the Bankruptcy Court during the course of the

                                        3
<PAGE>
Chapter 11 Case, provided, however, that no document shall be filed with the
Bankruptcy Court unless either there has been obtained prior to the filing
thereof an order of the Bankruptcy Court enabling US Airways to file those
portions of the documents under seal or portions of such filed documents
designated by GECC are redacted, in each case, as GECC shall request in its sole
discretion; (F) the professional advisors of the Official Committee of Unsecured
Creditors (the "Creditors' Committee"), but only to the extent that designated
portions of such material to be disclosed are redacted, in each case, as GECC
shall request in its sole discretion, members of the Creditors' Committee, and
(G) any potential debtor-in-possession ("DIP") lender and equity investors
provided that such entities shall, in each case prior to disclosure, execute a
confidentiality agreement in form and substance acceptable to GECC and GEAE. A
written summary of the Restructuring Transaction, approved by GECC in advance of
disclosing such summary, may be provided to (i) US Airways' and Group's labor
unions, (ii) any lender, potential lender, or participant, (iii) any material
stakeholder in US Airways' and Group's proposed restructuring, (iv) the
Creditors' Committee (but only if such summary has been redacted in a manner
satisfactory to GECC as provided above) or (v) such other third parties as the
parties hereto may mutually agree; provided that such parties described in (i) -
(v) above have executed a confidentiality agreement in form and substance
acceptable to GECC and GE Engine Services. The parties agree that the terms of
this Paragraph will survive any termination, through expiration or otherwise, of
the Term Sheets that are the subject hereof.

Subject to the conditions set forth in Schedule A, Schedule B and Schedule C
hereto with respect to the Phase I Transactions, the Phase II Transactions and
the Exit Restructuring Transactions, this Master MOU and the Term Sheets are
intended to create binding legal obligations among the parties. Reference is
made to the milestones and events described in Schedule D hereto (as the same
may be amended, each a "Global Event of Default").

This Master MOU may not be modified or amended in any manner other than in
writing duly executed by or on behalf of all of the parties hereto.

Once this Master MOU has been countersigned, the parties will proceed to
finalize appropriate definitive agreements and to commence the other steps that
will be necessary or appropriate to complete the transactions contemplated by
the Term Sheets.

This Master MOU may be executed in any number of counterparts, each of which
when so executed shall be deemed to be an original, and such counterparts
together shall constitute and be one and the same instrument.

                            [Signature pages follow.]

                                 annual interest rate shall be computed as the
                                 sum of (i) three-month US Dollar LIBOR, as

                                 basis. Interest may be paid in US dollars or in

                                 Chapter 11 Case. The "LIBOR Setting Date" shall
                                 be the date which is two (2) Business Days in
                                 advance of the applicable three-month LIBOR
                                 period.

LOAN REPAYMENT:                  Principal amounts and interest paid in kind due
                                 under the Bridge Notes will be payable in full

                                 rank equally in right of payment with all
                                 existing and future senior unsecured
                                 obligations of Issuer. The Notes are senior
                                 unsecured and thus are junior to Issuer's
                                 secured obligations to the extent of the value
                                 of the collateral securing such secured
                                 obligation.

CONVERSION RIGHTS:               The Holder may convert any number of the Notes
                                 into the Issuer's common stock (the "Common
                                 Stock"), at any time, at

----------
*    The parties will work together to set a coupon rate for the Notes no later
     than thirty (30) days prior to the scheduled date of emergence from the
     Chapter 11 Case which would be reasonably expected to result in the Notes
     trading at par upon emergence from the Chapter 11 Case (the "Par Value
     Interest Rate"). Failing agreement on the Par Value Interest Rate, the
     parties will solicit rate recommendation from three national trading firms
     and will adopt the average of the three suggested rates.

                                 the Conversion Price.

CONVERSION PRICE:                The product of (x) 140-150% (at Issuer's
                                 option) and (y) the average closing price of
                                 the Common Stock for the sixty (60) consecutive
                                 trading days following Issuer's emergence from
                                 the Chapter 11 Case and listing on NASDAQ or a
                                 national stock exchange from the Chapter 11
                                 Case.

                                 the Chapter 11 Case; the Notes and the
                                 underlying Common Stock will be freely

                                 listed on a national stock exchange by one
                                 hundred-eighty (180) days following emergence
                                 from the Chapter 11 Case. Failure to achieve
                                 such listing within one hundred-eighty (180)

                                 the option of the Issuer, on the fifth (5th)

MANDATORY PREPAYMENTS:           Mandatory repayment at upon a "fundamental
                                 corporate change" with a customary coupon

          Rev 5) between Group and GEES (the "CF34-3B1 Agreement")
          (as amended, individually, an "Agreement" and collectively, the
          "Agreements")

Gentlemen/Ladies:

This term sheet is being entered into with reference to the Master MOU, dated
November 24, 2004, among US Airways Group, Inc., US Airways, Inc. and General
Electric Capital Corporation (the "Master MOU"), and will be attached thereto as
Exhibit "H."

The following sets forth the understandings which have been reached by US
Airways, Group, GEES and General Electric Company ("GEC") in relation to the
Agreements and certain other matters. Except as otherwise indicated, capitalized
terms not defined herein have the meanings given those terms in each Agreement
or in the Master MOU.

US Airways, Group and their affiliates filed voluntary petitions for
reorganization under Chapter 11 of the Bankruptcy Code on September 12, 2004
(the "Petition Date").

US Airways and Group seek forgiveness of certain obligations arising under the
Agreements,

                                       24
<PAGE>
and wish to defer other obligations arising thereunder and to make certain
amendments thereto. GEES and GEC are willing to grant such forgiveness, to
accept such deferrals and to make such amendments, subject to the terms and
conditions contained in this term sheet.

The parties agree as follows:

1. The provisions of this term sheet shall be subject to the conditions that (i)
US Airways, Group and their affiliates shall be in compliance with all of their
obligations under the Master MOU and the other term sheets attached thereto, and
(ii) no default shall have occurred with respect to the US Airways Restructuring
Obligations, or with respect to any other obligations between US Airways, Group
and/or any affiliate and the GE Entities, except (a) any payments that relate
solely to a good faith dispute regarding the performance of GEES or any of its
affiliates under any engine maintenance agreement (including, without
limitation, the Agreements) between US Airways or any of its affiliates and GEES
or any of its affiliates, (b) any lease payments that relate solely to a good
faith dispute regarding the return of an aircraft past the scheduled or mutually
agreed termination of the lease of such aircraft provided that neither US
Airways nor any of its affiliates is operating such aircraft, and (c) any
obligations that have been forgiven or deferred pursuant to this term sheet so
long as, with respect to any deferral, such payments are made at the time
specified in this term sheet (a "Cross-Default").

2. Notwithstanding any other provision of this term sheet, in the event that, in
the currently pending case under the US Bankruptcy Code, (a) US Airways
consummates a chapter 11 plan of reorganization, including a liquidating chapter
11 plan, and neither it nor its successor under the plan continues to operate as
an airline, and US Airways' flight operations are, therefore, discontinued, or
(b) the 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, US Airways discontinues flight operations,
then US Airways, Group or GEES may (subject to any applicable notice periods)
terminate the Agreements; provided, however, that this sentence shall not apply
if US Airways sells a material portion of its assets to any purchaser that is
not, prior to entering into the transaction with US Airways, a certificated air
carrier (or a member of the same consolidated group). In the event the previous
sentence is applicable, the claims of GEES in respect of the Agreements in the
pending bankruptcy case shall be limited as follows: (x) GEES shall have an
allowed administrative expense priority claim under Bankruptcy Code Section
503(b)(1)(A) in the amount of $1 million, plus a sum equal to any unpaid
invoices for services rendered after September 12, 2004, but prior to the date
of termination; and (y) GEES shall have an unsecured (except as provided in the
next sentence) prepetition claim for all other claims and damages related to the
termination or breach of, or any other claims arising under the Agreements.
Nothing in this paragraph shall limit the rights of GEES to enforcement of any
and all mechanics or similar liens which secure any sums owed to GEES under the
Agreements or which arise in connection with services performed thereunder.

3. The parties intend that the Master MOU and the term sheets attached thereto,
including this term sheet, will be submitted for approval of the bankruptcy
court on December 16, 2004. This term sheet shall become effective upon approval
by the court. If the Master MOU and attached term sheets are not submitted and
approved by the court on such date, then GEES and GEC may at their option elect
not to consummate the transactions described in this term sheet. The parties
will undertake to agree upon definitive documents prior to the hearing date, so
that

                                       25
<PAGE>
documents can be submitted to the court and executed promptly, and in no event
later than five days following approval (the "Assumption Date"). The parties
agree that this term sheet and any final agreement resulting from this term
sheet will be filed with the court under rules which will cause only a redacted
counterpart to become publicly available.

4. GEES agrees to forgive and release US Airways from the following obligations
under the Agreements:

[REDACTED] Agreement

     -    Payment of the [REDACTED] and [REDACTED], described in Section 1,
          Article III, Paragraph E.

     -    Payment of the [REDACTED] and [REDACTED], described in Section 1,
          Article III, Paragraph F.

     -    Payment of the [REDACTED] and [REDACTED], described in Section 1,
          Article III, Paragraph G.

[REDACTED] Agreement

     -    Payment of the [REDACTED] and [REDACTED], described in Section 1,
          Article III, Paragraph G.

     -    Payment of [REDACTED], [REDACTED] through the date of this term sheet,
          under Section 1, Article III, Paragraph H [REDACTED]. For sake of
          clarity, US Airways shall remain liable for payment of the [REDACTED]
          and [REDACTED] from and after the date of this term sheet, all as
          provided in (and subject to) such paragraph and Section 1, Article
          III, Paragraph I, including, but not limited to, the provisions of
          those paragraphs for forgiveness of a portion of the [REDACTED] under
          certain circumstances. US Airways' obligation to pay the [REDACTED]
          shall be documented in a promissory note.

     -    Purchase of one [REDACTED] scheduled for [REDACTED].

[REDACTED]Agreement

     -    Payment of the[REDACTED] and [REDACTED], described in Section 1,
          Article III, Paragraph F.

5. GEES agrees to defer payment by US Airways of [REDACTED] arising under the
Agreements during the months of [REDACTED], detailed in [REDACTED] hereto (the
"Deferred Obligations"). US Airways shall repay the Deferred Obligations,
[REDACTED], on the earlier of [REDACTED] (the "Termination Date") and the date
that is [REDACTED] following confirmation of debtors' plan of reorganization.

6. The parties agree:

     -    to extend the [REDACTED] Agreement for an additional term of
          [REDACTED] years. Existing contract terms and conditions shall
          continue during the extension.

     -    that US Airways shall have a one-time option, upon notice given not
          later than [REDACTED], to either (a) convert the [REDACTED] Agreement
          to an exclusive [REDACTED] arrangement, effective [REDACTED], provided
          the GEES proposal for such arrangement is competitive with proposals
          received by US Airways from vendors of comparable recognized
          reputation, or (b) terminate the [REDACTED] Agreement.

                                       26
<PAGE>
     -    that [REDACTED] of the [REDACTED] Agreement shall be deleted.

     -    that GEES shall have [REDACTED] with respect to [REDACTED] for Group's
          [REDACTED] and, if any, [REDACTED]. In the event that [REDACTED],
          Group or US Airways shall enter into a [REDACTED] with [REDACTED] for
          these [REDACTED].

     -    that, subject only to the amendments expressly set forth in this term
          sheet, the Agreements shall be assumed by US Airways and Group by
          execution of definitive documents on or before the [REDACTED], and
          shall continue in full force and effect as amended. Thereafter,
          subject to paragraph 2 of this term sheet, US Airways and Group shall
          perform their obligations under the amended Agreements as they become
          due, including, but not limited to, [REDACTED] under Section 1,
          Article III (A)(3) of the [REDACTED] Agreement.

     -    that the [REDACTED] engine build standard will be [REDACTED] near the
          end of the Agreement, without further financial adjustment, yet in
          such a way that US Airways' financial exposure due to engine lease
          return conditions is not harmed.

7. It is a condition subsequent to the agreements of GEES and GEC under this
term sheet that US Airways consummates a chapter 11 plan of reorganization under
which it (or its successor under the plan) continues to operate as an airline by
the Termination Date. Subject to paragraph 2 of this term sheet, failure of this
condition will cause all sums, payment of which has been deferred pursuant to
the Agreements, as amended by this term sheet, to become immediately due and
payable, and GEES shall not be precluded from the enforcement of any and all
mechanics or similar liens which may secure payment of such sums.

8. The full balance of all payments deferred under the Agreements, as amended
pursuant to this term sheet (i.e., the Deferred Obligations and the Deferred
Charges under the CFM56-5 Agreement), (i) shall be paid unconditionally, without
set-off or demand at the time such payments are due and payable in accordance
with the Agreements as modified by this term sheet, and (ii) shall accelerate
and become immediately due and payable, and shall be paid without notice or
demand, upon the occurrence of any Cross-Default. Payments deferred under each
Agreement shall accelerate and become immediately due and payable upon
termination of such Agreement for any reason other than GEES' default.

9. Engine overhaul charges for MCPH engines which will remain in US Airways'
fleet will continue to be paid monthly under the terms of the Agreements.
Conversely, GE will seek to recover engine overhaul charges for MCPH engines
which will be rejected or abandoned by US Airways or affiliates, as
debtor-in-possession, from the engine owners. Recovery from engine owners will
not affect the obligation of US Airways, Group or their affiliates to pay
charges due upon removal of the engines pursuant to the Agreements (but GE will
credit any sums received from engine owners against the Deferred Obligations).
Removal charges which become due postpetition will be an administrative expense
under Section 503(b) of the Bankruptcy Code, and will be due and payable upon
removal of such engine pursuant to the Agreements. If any engine in GE's
possession is scheduled to be rejected or abandoned by US Airways or an
affiliate, but such rejection or abandonment has not become effective, GE will
release the engine to US Airways or such affiliate upon payment of the
applicable removal charges. So that GE can take appropriate action, US Airways
or Group shall identify each MCPH engine prior to return

                                       27
<PAGE>
following overhaul as one of the following:

-    To be returned to fleet.

-    Rejected/abandoned.

-    To be rejected/abandoned--removal charge will be paid upon return to US
     Airways or an affiliate.

This paragraph 9 shall not apply with respect to GECAS-owned engines, removed
from US Airways' fleet pursuant to the Master MOU and the term sheets thereunder
(the "GECAS Engines"). Reconciliation, including any return-to-service charges
and any removal charges and credits with respect to the GECAS Engines, shall be
waived.

10. With respect to the GE-Snecma Aircraft listed in Exhibit A, US Airways will
cooperate with documentation of permanent leases substantially equivalent to the
existing interim leases, and execution of permanent leases no later than
December 17, 2004 (which may be held in escrow pending foreclosure). In the
event that US Airways does not emerge from bankruptcy, the administrative claim
related to such permanent leases shall be limited to three months rent under
such leases and performance of return conditions. If required by existing
agreements, US Airways will reimburse legal fees owing upon execution of
permanent leases.

11. If GEES, GEC or their respective affiliates shall become entitled to file
any claim in the chapter 11 case pending with respect to US Airways as the
result of a Cross Default, or the failure of a condition precedent or subsequent
to any such obligation, or otherwise arising out of this term sheet and the
transactions contemplated hereby, such claim shall be deemed timely if filed
within 30 days following the date of the breach, failure of condition, or other
event giving rise to such claim, notwithstanding any deadline fixed by law or
the prior entry of any order setting a bar date for such claim or any equitable
argument that might preclude the filing of such a claim.

12. Without limiting any provisions of the Master MOU or other term sheets
thereunder, US Airways and Group will be responsible for reimbursement of
reasonable legal fees paid by GEC and GEES to their outside counsel in
connection with the negotiation, documentation and implementation of this term
sheet, including, but not limited to, drafting of definitive documents.

13. Subject to the consent of the ATSB loan parties, if required, (a) on behalf
of themselves and their affiliates, US Airways and Group waive their rights
under Bankruptcy Code Section 362 solely to the extent necessary in order that
GEES may take such actions as necessary, including filing with the appropriate
county register of deeds, to retain liens against aircraft engines arising in
the ordinary course under Kansas Statute 58-201, following performance of
overhaul services, and (b) US Airways agrees that the Agreements shall be
amended as necessary to authorize such filings.

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

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

hereunder in respect of the obligation of the Investor to make the investment

between Wexford and Republic, and each of Wexford, Republic and the Company
shall promptly thereafter execute and deliver to each other appropriate
documentation reflecting such allocation. Upon delivery of such notification,

conditions herein, shall be performed by Republic.

without limitation, projected cash balances, fleet composition, revenues, debt
levels, expenses, cash flows and such other projections and similar data and
information, including the detailed assumptions used to prepare such
projections, as would be required under the Bankruptcy Code to be included in a
disclosure statement related to the Plan (the "Initial Business Plan"). During
the twenty-one day period following the Investor's receipt of the Initial
Business Plan (such period, the "Initial Business Plan Review Period"), in
addition to and not by way of limitation of the obligations of the Company under
Section 7.01 hereof, the Company shall (and shall cause each of the Operating
Companies to) afford to the Investor, its Affiliates and their respective
Representatives access to all information, data, 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, including,
without limitation, all data, information and materials underlying the
assumptions in

                                       19

<PAGE>

the Initial Business Plan. Not later than the last day of the Initial Business
Plan Review Period, the Investor shall notify the Company in writing as to
whether the Investor approves or disapproves the Initial Business Plan,
including the assumptions underlying the Initital Business Plan, which
determination shall be made in the sole and absolute discretion of the Investor.
The failure by the Investor to give such notification within such twenty-one
(21) day period shall be deemed an approval of the Initial Business Plan.

               (b) If at any time and from time to time after the Company shall
have delivered the Initial Business Plan under Section 6.09(a) above (or an
Amended Business Plan (as defined below), the Company makes a material
modification or supplement to the Initial Business Plan, taken as a whole (as
modified or supplemented, an "Amended Business Plan"), the Investor shall have
the same rights to approve in its sole and absolute discretion such Amended
Business Plan, in the manner provided in Section 6.09(a), and the Company's
obligations and the Investor's rights under Section 6.09(a) shall apply mutatis
mutandis to this 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.

          Section 6.10 Effectiveness Prior to Omnibus Order. The parties agree
that unless and until the Omnibus Order has been entered, except with respect to
the parties' obligations under Sections 2.04, 6.01, 6.02, 6.05, 6.08, 7.02,
Article IX and Sections 10.03 through 10.11 of Article X, and any related
provisions regarding the parties' obligations regarding filing of the Motion and
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.

          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.

          Section 7.03 Registration Rights and Listing of New Common Stock.
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 which shares of New
Common Stock are first distributed under the Plan to the holders of allowed,
unsecured claims in the Cases, and thereafter agrees that

                                       21

<PAGE>

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 occurs, to cause the Investor to

this Agreement at the Closing.

          Section 7.07 Chautauqua Pre-Petition Claim. The Company agrees that
the general unsecured pre-petition claims of Chautauqua under the Original Jet
Service Agreement shall be allowed, none of the Company nor any of its
Subsidiaries shall challenge or dispute (or support any challenge) such claim
and the Omnibus Order shall contain provisions to such effect, provided,
however, that the Company 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.

                                  ARTICLE VIII

                                   CONDITIONS

the Investor to make the Investment pursuant to Section 2.01 hereof is subject
to satisfaction or waiver of each of the following conditions precedent:

               (a) Definitive Documents. Definitive Transaction Documents
necessary to consummate the Transactions shall have been prepared, negotiated
and, to the extent applicable, executed by the parties (or, as applicable, their
Affiliates), and approval by the Bankruptcy Court of such documents pursuant to
a Final Order, as necessary, shall have been obtained. All Transaction Documents
(in form and substance satisfactory to the Investor), to the extent applicable,
shall have been executed by the parties thereto (other than the Investor and its
Affiliates) on or prior to the Effective Date, shall not have been modified,
shall be in effect and the consummation of the transactions contemplated thereby
shall not be stayed, and all conditions to the obligations of the parties under
the Transaction Documents shall have been satisfied or effectively waived. All
corporate and other proceedings to be taken by the Company or its Affiliates in
connection with the Transaction Documents and the transactions contemplated

                                       22

<PAGE>

thereby to be completed at the Closing and documents incident thereto shall have
been completed in form and substance satisfactory to the Investor, and the
Investor shall have received all such counterpart originals or certified or
other copies of the Transaction Documents and such other documents as it may
reasonably request.

               Without limiting the generality of the foregoing, in connection
with the consummation of the Plan, the reorganized Company and the Investor
shall have entered into certain agreements relative to the Investor's investment
in the reorganized Company, as follows:

                    (i) The Investor and the reorganized Company shall have
entered into a shareholders agreement with the other Substantial Investor(s)
containing customary terms and conditions reasonably acceptable to the Investor,
including, without limitation, provisions intended to preserve the corporate
governance agreements provided for above, provisions providing appropriate
representation on committees of the Board, and restrictions on transactions by
the reorganized Company or its Subsidiaries with Affiliates and to supercede the
provisions in Sections 7.01, 7.02, 7.03 and 7.04.

                    (ii) The Investor and the reorganized Company shall have
entered into an investor rights agreement with the other Substantial Investor(s)
containing customary terms and conditions reasonably acceptable to the Investor,
including, without limitation, rights typically available to significant equity
investors, including rights commonly referred to as "tag-a-long rights,"
"registration rights" and "piggyback registration rights."

               (b) Delivery. The reorganized Company shall have executed and
delivered to the Investor the shares of New Common Stock pursuant to and in
accordance with Section 2.01 hereof.

               (c) Board Representation. As contemplated by Section 5.01 hereof,
the Investor Directors designated by the Investor shall have been elected or
appointed to the Board effective as of the Closing Date.

               (d) Approvals. The Company shall have received (i) all material
Regulatory Approvals, which shall have become final (provided that, if an appeal
of such Regulatory Approval is pending and such appeal has a significant
possibility of being resolved adversely to the Company in a manner that would
reasonably be expected to have a material adverse effect on the ability of the
Investor or the Company or their respective Affiliates to consummate the
Transactions, this clause (i) shall be deemed not to be satisfied), and (ii) all
other material approvals, permits, authorizations, exemptions, consents,
licenses and agreements from other third parties that are necessary to permit
the Transactions to be completed or performed as contemplated by the Transaction
Documents and to permit the reorganized Company and its Affiliates to carry on
its business after such transactions in a manner not materially inconsistent
with the manner in which it was carried on prior to the Effective Date (together
with the Regulatory Approvals, the "Approvals"), which Approvals shall not
contain any condition or restriction that, in the Investor's reasonable
judgment, materially impairs the reorganized Company's ability to carry on its
business. Subject to the proviso in the first sentence of Section 6.01(a), all
waiting periods imposed by applicable Law (including, without limitation, under
the HSR Act) in connection with the Transactions shall have expired or been

                                       23

<PAGE>

terminated without any action having been taken by any court of competent
jurisdiction restraining, preventing or imposing materially adverse conditions

have instituted any legal proceeding that seeks to restrain, enjoin, prevent,
delay, prohibit or otherwise make illegal the performance of any of the

individually or in the aggregate, reasonably be expected to have a material
adverse effect on the ability of the Investor or the Company or their respective
Affiliates to consummate the Transactions, and (iv) there is no pending or
threatened investigation or litigation by any other Person relating to the
Transactions which, if determined adversely to the Company or the Investor,

contained in this Agreement, which breach would result in the failure to satisfy
any condition set forth in Section 8.01 hereof to the Investor's obligations and
that has not been cured within thirty (30) days following receipt by the Company
of written notice from the Investor of such breach, or (ii) any condition set

being satisfied;

               (c) the Company, if (i) there shall have been a breach by the
Investor of any material representation, warranty, covenant or agreement
contained in this Agreement which breach would result in the failure to satisfy
any condition set forth in Section 8.02 hereof to the Company's obligations and

force and effect except that (i) the terms and provisions of this Section 9.02

9.01(c) or (d), the one-time option to acquire the Owned Aircraft and the Leased
Aircraft in Section 6.03, as more fully described in Exhibit B, shall remain in
full force and effect and (ii) any termination of this Agreement shall not

by their terms survive termination.

          Section 10.01 Fees and Expenses. (a) Upon the Effective Date, the
Company shall pay to the Investor non-refundable fully paid fees as follows: (i)

               (b) Except as expressly provided herein or in any Transaction

Agreement or prevent any violation hereof and, to the extent permitted by

documents described herein (including the Plan) or 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 any other party hereto prior to or after the date hereof shall stop or
prevent the exercise of any right hereunder or be deemed to be a waiver of any
such right.

          Section 10.07 Counterparts. This Agreement may be executed in two or
more counterparts, each of which shall be deemed to constitute an original, but
all of which together shall constitute one and the same document.

and to be performed in that State without reference to its conflict of laws
rules. The parties hereto agree that the appropriate and exclusive forum for any
disputes arising out of this Agreement solely between the Company and the
Investor shall be the Bankruptcy Court, or if such court will not hear any such
suit, the U.S. District Court for the Southern District of New York, and, the
parties hereto irrevocably consent to the exclusive jurisdiction of such courts,
and agree to comply with all requirements necessary to give such courts
jurisdiction. The parties hereto further agree that the parties will not bring
suit with respect to any disputes arising out of this Agreement except as
expressly set forth below for the execution or enforcement of judgment, in any
jurisdiction other than the above specified courts. Each of the parties hereto
irrevocably consents to the service of process in any action or proceeding
hereunder by the mailing of copies thereof by registered or certified airmail,
postage prepaid, to the address specified in Section 10.06 hereof. The foregoing
shall not limit the rights of any party hereto to serve process in any other
manner permitted by the Law or to obtain execution of judgment in any other
jurisdiction. The parties further agree, to the extent permitted by Law, that
final and non-appealable judgment against any of them in any action or
proceeding contemplated above shall be conclusive and may be enforced in any
other jurisdiction within or outside the United States by suit on the judgment,
a certified or exemplified copy of which shall be conclusive evidence of the
fact and the amount of indebtedness. THE PARTIES AGREE TO

                                       31

provided herein, the provisions hereof shall inure to the benefit of, and be
binding upon, the Company's and the Investor's successors and assigns. Neither
this Agreement nor any rights or obligations hereunder shall be assignable by
any party hereto without the prior written consent of the other party hereto,
provided that (i) Republic shall be permitted to assign all or any portion of
its rights and obligations hereunder to any of its wholly owned Subsidiaries, so
long as such Subsidiaries are Certificated Air Carriers (if required in
connection with the rights or obligations being assigned) and capable of
performing each of Republic's obligations and agreements proposed to be
assigned, without any other party's consent and (ii) Wexford shall be permitted
to assign all or any portion of its rights and obligations hereunder to any of
its Affiliates so long as such Affiliate has the financial resources to perform
each of Wexford's obligations and agreements proposed to be assigned, without
any other party's consent; and provided further that such assignee Subsidiary or
Affiliate is not a "major airline" or "low cost carrier", as such terms are
commonly understood in the airline industry, or an Affiliate thereof.

          Section 10.10 No Third-Party Beneficiaries. This Agreement is for the
sole benefit of the parties hereto and their respective successors and permitted
assigns and nothing herein, express or implied, is intended or shall confer upon
any other Person any legal or equitable right, benefit or remedy of any nature
whatsoever under or by reason of this Agreement, except that the provisions of

or pursuant to any listing agreement with or requirement of any relevant
national exchange or national quotation system) without appropriate
confidentiality agreements with such third parties being in place that are
reasonably acceptable to the other parties hereto.

                                   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.

               (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 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 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").

<PAGE>

                    (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.

          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

          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

<PAGE>

the Currently Owned Aircraft from the date of the Investment Agreement to
Closing, (iii) less assumed depreciation of $55,000 per aircraft per month,
commencing October 1, 2005 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).

               (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 380 miles and approximately
a 10.2 hour daily block hour utilization, 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

<PAGE>

          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

<PAGE>
          (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 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

                                       47

<PAGE>
 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.

                         ADDITIONAL JET SERVICE AIRCRAFT

          The completion of the transactions contemplated in this Exhibit E is
subject to the negotiation and execution of definitive documentation
incorporating the terms set forth in this Exhibit E 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.

          In the event that the Closing under the Investment Agreement occurs,
the Company will have the option to have Republic purchase, finance, and operate
for US Airways in US Airways Express service an additional six (6) EMB-170
aircraft and sixteen (16) additional EMB-170 or EMB-190 aircraft (the
"Additional Jet Service Aircraft"). The agreement to place such aircraft into
service is subject to Republic's ability to secure financing for such aircraft
predicated upon lease rates calculated in accordance with the Lease Formula on
Exhibit F, subject to mutual agreement on delivery dates and notices.

          Republic will operate the Additional Jet Service Aircraft as US
Airways Express under the terms of the New Jet Service Agreement, as amended in
accordance with Exhibit D.

Notes:

1) The [REDACTED] is the Maximum Lease Rate (in the case of [REDACTED] ERJ
[REDACTED] aircraft being leased by Investor to US Airways) and the Maximum
Reimbursement Rate (to the extent the aircraft are being flown by Investor under
the JSA) for such aircraft being purchased by the Investor at a price of
[REDACTED]; provided however that to the extent the Fixed Rate Base increases
above or decreases below the [REDACTED] rate used in this model to arrive at the
[REDACTED] Aircraft Lease Rate, the Maximum Lease Rate and Maximum Reimbursement
Rate, as applicable, will be recalculated using the actual Fixed Rate Base; such
calculation shall be made upon the closing of the purchase of the aircraft.

2) To the extent that the Investor is able to [REDACTED], the Aircraft Lease
Rent will be adjusted downward by [REDACTED] of the difference between the
Maximum Lease Rate, or Maximum Reimbursement Rate, as applicable, as calculated
above and the debt service calculated assuming a loan at [REDACTED] of Aircraft
price, self liquidating over [REDACTED] with [REDACTED] payments [REDACTED],
using the lower Spread [REDACTED] used in determining the rate on the loan;
provided however that if a different base rate, such as [REDACTED], is used
instead of [REDACTED], the difference between [REDACTED] will be added to the
Spread; further provided that the savings will be calculated only after
reimbursing Republic for the third party legal, brokerage, fees to lender, and
other out of pocket costs associated with securing the financing, which costs
shall be reimbursed by capitalizing them into the debt.

3) To the extent that the Investor acquires any additional aircraft beyond the
[REDACTED] ERJ [REDACTED] aircraft, the lease/reimbursement rate shall be based
on the actual Aircraft Price and actual Fixed Rate Base used to determine the
rate on the loan, plus the actual Spread required by the lender. To the extent
that this spread is in excess of [REDACTED] bps, US Airways shall have the right
not to have the Investor place the aircraft into service under the JSA.

                              SEC REPORTS NOT FILED

Following the distribution to employees of their grants of Common Stock of the
Company as restricted stock in August, 2003, pursuant to the Plan of
Reorganization after 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.
