                    DISPOSITION AND REDEVELOPMENT AGREEMENT

         THIS AGREEMENT is entered into by and between the CITY OF PHOENIX,
ARIZONA ("City") and AMERICA WEST AIRLINES, a Delaware corporation
("Developer"). The City and the Developer agree as follows:

ARTICLE I. SUBJECT OF AGREEMENT

         SECTION 101. PURPOSE OF AGREEMENT

         The purpose of this Disposition and Redevelopment Agreement
("Agreement") is to put into effect the Sky Harbor Center Redevelopment Area
Plan for a redevelopment project (the "Project") by providing for the
disposition and development of certain real property designated and referred to
herein as the "Site". The development of the Site pursuant to this Agreement,
and the fulfillment generally of this Agreement, are in the vital and best
interests of the City of Phoenix and the health, safety, and welfare of its
residents, and in accord with the public purposes and provisions of applicable
federal, state, and local laws and requirements and, pursuant to Arizona Revised
Statutes Section 9-500.11, will assist in the creation or retention of jobs or
will otherwise improve or enhance the economic welfare of the inhabitants of the
City of Phoenix.

         SECTION 102. REDEVELOPMENT PLAN

         This Agreement shall be subject to the provisions of the Sky Harbor
Center Redevelopment Area Plan, approved on April 24, 1985 by the City Council
of the City of Phoenix by Resolution No. 16569, which is incorporated herein by
this reference and made a part hereof as though fully set forth herein.

         SECTION 103. THE SITE

         The Site consists of approximately 27 acres generally located at the
northwest corner of Buckeye Road and the Papago Freeway (I-10), in Phoenix,
Maricopa County, Arizona, within the portion of the Redevelopment Area legally
described as PHOENIX SKY HARBOR CENTER, PHASE 1, according to the plant of
record in the Office of the County Recorder of Maricopa County, Arizona, in Book
341 of Maps at page 37. The Site is comprised of approximately 13 acres,
<PAGE>   5
hereinafter defined as the "Initial Parcel", which includes the "Development
Parcel" and the "Driveway Parcel", and an adjacent parcel containing
approximately 13 acres, hereinafter defined as the "Option Parcel."

         SECTION 104. PARTIES TO THE AGREEMENT

                  SECTION 104.1 THE CITY

         The City is a municipal corporation of the State of Arizona, a public
body corporate, exercising governmental functions and powers pursuant to the
Slum Clearance and Redevelopment Act of the State of Arizona. The execution of
this Agreement and any other documents required to implement the provisions of
this Agreement was authorized by Ordinance No. S-26932, passed by the Phoenix
City Council on March 15, 2000.

         The principal office of the City is located at 200 West Washington
Street, Phoenix, Arizona, 85003-1611.

         "City" as used in this Agreement, includes the City of Phoenix, the
Community and Economic Development Department and any assignee or delegate of or
successor to their rights, powers and responsibilities under the Arizona Slum
Clearance and Redevelopment Law.

         The obligations, approvals and other actions by the City under this
Agreement are the exercise of redevelopment powers for the purpose of compliance
with the redevelopment considerations expressed in this Agreement, and is not an
agreement as a municipality exercising regulatory powers. The Developer
hereunder still must comply with land use regulations, codes and laws affecting
the acquisition, ownership, use, improvement and development of property, and
the vacation and abandonment of public rights-of-way and easements. Nothing in
this Agreement constitutes an exemption or grant of a variance from applicable
codes and laws.

                  SECTION 104.2 THE DEVELOPER

         Developer, America West Airlines, a Delaware corporation authorized to
do business in Arizona.

                                       2
<PAGE>   6
         The principal office of the Developer is located at 4000 East Sky
Harbor Boulevard, Arizona 85___.

         Notwithstanding any other provisions hereof, all of the terms,
covenants, and conditions of this Agreement shall be binding on and shall inure
to the benefit of the Developer and the permitted successors and assigns of the
Developer. Wherever the term "Developer" is used herein, such term shall include
any such permitted successors and assigns.

                  SECTION 104.3 PROHIBITION AGAINST CHANGES IN OWNERSHIP.
                                MANAGEMENT AND CONTROL OF DEVELOPER

         (a) The Developer represents and agrees that the leasing and
development of the Site and other undertakings pursuant to this Agreement are
and will be used for the purpose of redevelopment of the Site and not for
speculation in landholding. The Developer further recognizes:

                  (i)      the importance of the redevelopment of the Site to
                           the general welfare of the community; and

                  (ii)     the substantial financing and other public aids that
                           have been made available by law and by the government
                           for the purpose of making such redevelopment
                           possible; and

                  (iii)    the fact that a significant change in ownership or
                           control of the Developer or of a substantial part
                           thereof, as defined in this Section 104.3 of this
                           contract, is for practical purposes a transfer or
                           disposition of the Site; and

                  (iv)     the fact that the Site is not to be acquired or used
                           for speculation, but only for development by
                           Developer in accordance with this Agreement.

In view of the foregoing, the qualifications and identity of the Developer, its
partners and principals, are of particular concern to the City. The Developer
further recognizes that it is because of such qualifications and identity that
City is entering into this Agreement with Developer. No voluntary or involuntary
successor in

                                        3
<PAGE>   7
interest of Developer shall acquire any rights or powers under this Agreement
except as expressly set forth herein.

         (b) The Developer shall promptly notify the City of any and all changes
whatsoever in the identity of the parties associated with the Developer, in
joint ventures or partnerships for the purpose of acquiring and developing the
Site or any part thereof as hereinabove provided, which are known to the
Developer or its officers. Except as provided in this Agreement, this Agreement
may be terminated by the City if there is any significant change (voluntary or
involuntary) in the ownership or control of the Developer (other than such
changes occasioned by the public trading of stock which does not result in a
change in the present control of Developer), that has not been approved in
writing by the City at the time of such change, which approval may be given or
withheld in City's absolute discretion, prior to the issuance of Certificates of
Occupancy for construction of all minimum required development on the Site as
more fully described in Article 10 of the Development Lease referenced in
Section 201 below.

         (c) Within ten (10) calendar days after receipt of a written request
from the City, Developer shall provide the City with a copy of any contract,
agreement, document and related papers which directly or indirectly conveys,
assigns or changes Developer's interest as outlined in this Section 104.3. The
Developer agrees to and shall indemnify and hold City harmless from or against
all claims, demands and obligations asserted by or from any party claiming a
right, interest or ownership to this Agreement, the Site or the Development
thereof through or with Developer arising out of or in connection with
relationships entered into by Developer or its partners with such other party.

                  SECTION 104.4 INDEPENDENT CONTRACTOR

         Developer is an independent contractor in the performance of all
activities, functions, duties and obligations pursuant to this Agreement.
Developer or City are not and shall not be considered as joint venturers,
partners or agents of each other. Developer's officers, employees, agents and
subcontractors shall not be considered as officers, employees or agents of the
City. The City and Developer hereby agree not to represent to anyone that they
are agents of one another or have authority to act on behalf of one another.

lease with the City for the Initial Parcel. The lease ("Lease") shall be
substantially in the form attached hereto as Attachment No. 1. Failure to timely

further notice or action by the City, notwithstanding anything contained herein
to the contrary. Upon timely execution and delivery of the Lease, this Agreement
shall terminate, and all of the rights and obligations of the parties shall be
governed solely by the terms and conditions of the Lease.

         SECTION 203. CONVEYANCE OF LEASEHOLD

                  SECTION 203.1 TITLE INSURANCE

         The City and Developer shall request a preliminary title commitment

Lease execution and prior to exercise of the option to lease each Option Parcel;
provided, however, that the City shall be under no obligation to cure any title
exceptions contained therein.

                                        5

         (b)      Recording fees.

         (c)      Notary fees.

                  SECTION 203.2 CONVEYANCE OF LEASEHOLD INTEREST AND DELIVERY OF

         Subject to any mutually agreed upon extensions of time, conveyance of

this Agreement. The City and the Developer agree to perform all acts necessary
for conveyance in sufficient time for the property interest to be conveyed in
accordance with the foregoing provisions.

         Possession shall be delivered to the Developer concurrently with the
conveyance of the leasehold interest, except that access and entry by Developer
may be granted before conveyance as permitted pursuant to this Agreement.

                  SECTION 203.3 EXECUTION OF LEASE BY CITY

         Subject to any mutually agreed upon extensions of time, the City shall
execute the Lease and the Memorandum of Lease upon receipt of all fees and other
amounts required to be paid by Developer prior to Lease execution pursuant to

                  SECTION 203.4 RECORDATION OF DOCUMENTS

         The City shall file the Memorandum of Lease and any other instruments

<PAGE>   10
                  SECTION 203.5 TAXES AND ASSESSMENTS

         Ad valorem taxes and assessments, if any, on the Site and taxes upon
this Agreement or any rights thereunder, levied, assessed, or imposed for any
period prior to the conveyance of any leasehold and other interests thereto,
shall be borne by the City. Any taxes and assessments levied, assessed or

subject to the terms and conditions of the Lease with respect thereto.

                  SECTION 203.6 CONDITION OF THE SITE

         The Site shall be conveyed in an "as is" condition with no warranty,
express or implied, by the City as to title or the condition of the soil, its
geology or the presence of known or unknown faults. It shall be the sole
responsibility of the Developer at its expense to investigate and determine
whether or not the proposed development can be constructed on the Site. If, in
the opinion of Developer, the conditions are not in all respects suitable for
the use or uses to which the parcels will be put, and Developer still wishes to
proceed with the leasing of the Site, then it is the sole responsibility and
obligation of the Developer, at Developer's expense, to take such action as may
be necessary to place the Site in a condition suitable for its development.

                  SECTION 203.7 ACCESS TO AND ENTRY BY THE DEVELOPER UPON THE
                                SITE

         Prior to the conveyance of the leasehold, representatives of the
Developer or its agents, employees, designees and nominees, shall have the right
of access to and entry upon the Site to be leased at all reasonable times, for
the purpose of obtaining data and making surveys and tests necessary to carry
out this Agreement. The Developer agrees to and shall indemnify and hold the
City harmless from any and all injuries or damages arising out of any work or
activity of the Developer, its respective agents, employees, designees and
nominees.

         The City agrees to provide, or cause to be provided, to the Developer
all data and information pertaining to the Site and available to the City when
requested by the Developer.

                  SECTION 203.8 OBLIGATIONS OF CITY AND DEVELOPER WHICH ARE
                                CONDITIONS PRECEDENT TO LEASE EXECUTION BY CITY

         (a) Subject to any mutually agreed upon extensions of time, which shall
not be unreasonably withheld, and also subject to the satisfaction of all
conditions contained herein or the waiver of any such condition by the party who
is affected thereby, the City shall execute the Lease on or prior to the date
specified therefor in this Agreement.

         (b) The obligation of City to execute the Lease is conditioned upon
receipt of the following:

                  (i)      All fees payable by Developer pursuant to this
                           Section 202;

                  (ii)     Delivery to the City of a Development Lease and
                           Memorandum of Lease previously approved as to form by
                           the City and signed (in triplicate) by the Developer;
                           and

                  (iii)    Approval by the City of a legal description of the
                           Site (which shall separately describe the areas
                           designated by the City for the Initial Parcel and the
                           Option Parcel) and a conceptual site for the Initial
                           Parcel, which shall have been prepared by Developer
                           at Developer's sole expense.

         (c) Notwithstanding any provision contained herein to the contrary, the
parties hereto agree that Developer shall have no obligation to execute the
Lease if, in the opinion of Developer, conditions are not in all respects
suitable for the use or uses to which the parcel will be put, or if Developer
has not approved any aspects of its due diligence with respect to this Site

orientation, age or disability. Such action shall include, but not be limited to
the following: employment, upgrading, demotion or transfer; recruitment or
recruitment advertising; layoff or termination; rates of pay or other forms of

ARTICLE IV. DEFAULTS, REMEDIES AND TERMINATION

         SECTION 401. DEFAULTS - GENERAL

         Subject to the extensions of time set forth in Section 505, failure or
delay by any party to perform any term or provision of this Agreement
constitutes a default under this Agreement. Except as provided in Section 201
above, the party who so fails or delays must immediately commence to cure,
correct, or remedy such failure or delay, and shall complete such cure,
correction or remedy with reasonable diligence.

         A nondefaulting party shall give written notice of default to the party
in default, specifying the default complained of by the injured party. Failure
or delay in giving such notice shall not constitute a waiver of any default, nor
shall it change the time of default.

         Except as otherwise expressly provided in this Agreement, any failure
or delay by any party in asserting any of its rights or remedies as to any
default, shall

                                       11
<PAGE>   15
not operate as a waiver of any default, or of any such rights or remedies, or
deprive either such party of its right to institute and maintain any actions or
proceedings which it may deem necessary to protect, assert or enforce any such
rights or remedies.

         SECTION 402. INSTITUTION OF LEGAL ACTIONS

         In addition to any other rights or remedies, either party may institute
legal action to cure, correct or remedy any default, to recover damages for any
default, or to obtain any other remedy consistent with the purpose of this
Agreement. Such legal actions may be instituted in the County of Maricopa, State
of Arizona, or in the Federal District Court in the District of Arizona.

         If any legal action is instituted pursuant to this Agreement, the
prevailing party in such action shall be reimbursed by the other party for all
costs and expenses of such action, including reasonable attorneys' fees as may
be fixed by the Court

         SECTION 403. APPLICABLE LAW

         The laws of the State of Arizona shall govern the interpretation and
enforcement of this Agreement.

         SECTION 404. ACCEPTANCE OF THE LEGAL PROCESS

         In the event that any legal action is commenced by the Developer
against the City, service of process on the City shall be made by personal
service upon the City Clerk of the City of Phoenix, or in such other manner as
may be provided by law.

         In the event that any legal action is commenced by the City against the
Developer, service of process shall be made by personal service or in such other
manner as may be provided by law, whether made within or without the State of
Arizona.

         SECTION 405. RIGHTS AND REMEDIES ARE CUMULATIVE

         Except as otherwise expressly stated in this Agreement, the rights and
remedies of the parties are cumulative, and the exercise by any party of one or
more of such rights or remedies shall not preclude the exercise by it, at the
same time or different times, of any other rights or remedies for the same
default or any other default by such defaulting party.

         SECTION 406. REMEDIES

                 SECTION 406.1. DAMAGES

         (a) NOTICE AND CURE

         If any party defaults with regard to any of the provisions of this
Agreement except in the event of Developer's failure to timely sign and deliver
the Lease as required pursuant to Section 201, which shall result in immediate
termination of this Agreement without notice or time to cure, a nondefaulting
party shall deliver written notice of such default upon the defaulting party. If
the default is not commenced to be cured within thirty (30) calendar days after
service of the notice of default and is not cured promptly in a continuous and
diligent manner within a reasonable period of time after commencement, the
defaulting party shall be liable to the nondefaulting parties for any damages
caused by such default, and the nondefaulting parties may thereafter (but not
before) commence an action for damages against the defaulting party with respect
to such default.

         (b) LIMITATION ON DAMAGES

         Anything herein to the contrary notwithstanding, neither City nor
Developer shall in any event be responsible or liable for consequential,
exemplary or punitive damages as a result of any act or omission in connection
with this Agreement.

                  SECTION 406.2. SPECIFIC PERFORMANCE

         If any party defaults with regard to any of the provisions of this
Agreement except Section 201, default of which shall result in immediate
termination of this Agreement without notice or time to cure, the nondefaulting
parties shall serve written notice of such default upon the defaulting party. If
the default is not

                                       13
<PAGE>   17
commenced to be cured within thirty (30) calendar days after service of the
notice of default and is not cured promptly in a continuous and diligent manner
within a reasonable period of time after commencement, a nondefaulting party, at
its option, may thereafter (but not before) commence an action for specific
performance of the terms of this Agreement pertaining to such defaults.

                  SECTION 406.3 RIGHTS OF TERMINATION

         (a) TERMINATION BY DEVELOPER

         The Developer, at its option, may terminate this Agreement prior to
conveyance of the leasehold if: (i) the City, in breach of this Agreement, does
not tender conveyance of a leasehold, or deliver possession thereof, in the
manner and condition and by the date provided in this Agreement or fails to
perform any condition precedent thereto, and such failure is not cured within
thirty (30) calendar days after written demand by the Developer; or (ii) the
condition of the Site is determined to be unsuitable for development. In the
event of such termination, neither party shall have any further rights or
liabilities hereunder.

         (b) TERMINATION BY CITY

         The City at its option may terminate this Agreement immediately and
without further notice or action by City if:

         (i)      The Developer assigns or attempts to assign and/or convey this
                  Agreement (or any rights therein) in violation of this
                  Agreement;

         (ii)     City does not receive from Developer all items required under
                  Article II above within the times specified;

         (iii)    The Developer shall fail to perform any other obligations and
                  duties provided in this Agreement within the time for
                  performance specified therefor, or if no such time is
                  specified, within thirty (30) calendar days after the date of
                  written demand by the City to the Developer to perform such
                  obligation and duty.
