the over-the-counter market, on a national securities exchange or otherwise at
fixed prices which may be changed, at market prices prevailing at the time of
sale, at prices related to such market prices or at negotiated prices. The
Selling Securityholders may effect such transactions by selling the Securities
to or through underwriters, dealers or agents who may receive compensation in
the form of discounts, concessions or commissions from the Selling
Securityholders or the purchasers of the Securities for whom such underwriters,
dealers or agents may act. The Company will not receive any of the proceeds from
the sale of any of the Securities by the Selling Securityholders.
    
 
   
     Holders of Class B Common Stock are entitled to one vote per share, and
holders of Class A Common Stock are entitled to 50 votes per share on all
matters submitted to a vote of common stockholders, except that voting rights of
holders who are not United States citizens are limited as described herein. The
Senior Notes bear interest payable semiannually in arrears. The Senior Notes may
be redeemed at the option of the Company (i) prior to September 1, 1997, at any
time, at a redemption price equal to 105% of the principal amount or from time
to time in part from the net proceeds from a public offering of its capital
stock at a redemption price equal to 105% of the principal amount, in each case
plus accrued and unpaid interest, if any, to the redemption date; and (ii) on or
after September 1, 1997 at any time in whole or from time to time in part, at
redemption prices described herein. In addition, Senior Notes may be subject to
mandatory redemption, at a redemption price of 104% of the aggregate principal
amount of Senior Notes so redeemed, plus accrued and unpaid interest thereon,
under certain circumstances following the consummation of a public offering of
the Company's capital stock. The Senior Notes will be effectively subordinated
to $480.9 million of secured indebtedness incurred by the Company to acquire
aircraft and other assets (the "Secured Debt"). Holders of the Secured Debt will
be senior to the holders of the Senior Notes with respect to the collateral
securing such indebtedness. See "Description of the Senior Notes." Prior to this
registration, there has been no public market for any of the Securities.
Application has been made to list the Class B Common Stock and the Warrants on
the New York Stock Exchange. The Company does not intend to file an application
to have either the Class A Common Stock or the Senior Notes listed on a national
exchange and does not expect an active trading market to develop for either the
Class A Common Stock or the Senior Notes.
    
 
   
     The Selling Securityholders and any underwriters, dealers or agents
participating in the distribution of the Securities may be deemed to be
"underwriters" within the meaning of the Securities Act of 1933 as amended (the
"Securities Act"), and any profit on the sale of the Securities by the Selling
Securityholders and any commissions received by any such underwriters, brokers,
dealers or agents may be deemed to be underwriting commissions or discounts
under the Securities Act. Pursuant to the terms of the Registration Rights
Agreement (as hereinafter defined) the Company has agreed to indemnify the
Selling Securityholders against certain liabilities, including liabilities under
the Securities Act.

Securities should confirm the registration thereof under the securities laws of
the state in which such transactions will occur, or the existence of any
exemption from registration.

                               PROSPECTUS SUMMARY
 
     The following summary information is qualified in its entirety by the
detailed information and financial statements (including the notes thereto)
appearing elsewhere in this Prospectus, which should be read in its entirety.
Prospective investors should carefully consider matters discussed under the
caption "Investment Considerations."
 
                                  THE COMPANY
 
   
     America West Airlines, Inc. ("America West" or the "Company") is a major
United States air carrier providing passenger, cargo and mail service with its
primary markets in the western and southwestern regions of the United States.
The Company operates its route system through two principal hubs, Phoenix,
Arizona and Las Vegas, Nevada, and a mini-hub in Columbus, Ohio. As of July 31,
1994, America West operated a fleet of 85 jet aircraft and provided service to
45 destinations. Through alliance agreements with Mesa Airlines, Inc. ("Mesa"),
the Company provides connecting service to an additional 18 destinations. The
Company also has formed an alliance with Continental Airlines, Inc.
("Continental") to serve additional destinations.
    
 
   
     The Company filed a voluntary petition for protection under Chapter 11 of
the federal bankruptcy code on June 27, 1991. The Company's plan of
reorganization (the "Plan") was confirmed by the United States Bankruptcy Court
for the District of Arizona (the "Bankruptcy Court") on August 10, 1994. The
Plan will become effective on the date (the "Effective Date") on which certain
conditions specified in the Plan are satisfied or waived, which the Company
expects to occur on or about August   , 1994. In connection with its
reorganization in bankruptcy and related operational restructuring (the
"Reorganization"), the Company took significant steps to improve its operations,
including (i) reducing its fleet size from 123 aircraft in July 1991 to 85 at
July 31, 1994, facilitating a better matching of capacity to demand through
elimination of nonproductive routes; (ii) reducing the aircraft types operated
from five to three, resulting in reduced operating costs; (iii) implementing
certain enhancements to its revenue management system to optimize the level of
passenger revenues generated on each flight; (iv) eliminating Company operated
commuter service and introducing code sharing agreements to expand the scope of
service and attract a broader passenger base; and (v) implementing numerous cost
reduction programs, including a Company-wide pay reduction in August 1991 and
the reduction of aircraft lease rentals to fair market rates in the fall of
1992. As a result of these measures as well as a gradually improving economic
climate and a more stable environment relative to fare competition within the
airline industry, America West was one of only two major airlines to report a
profit in each quarter of 1993, realizing net income for 1993 of $37.2 million
and operating income of $121.1 million on revenues of $1.33 billion.
    
 
     America West currently operates with one of the lowest cost structures
among major U.S. airlines, based on reported 1993 results. America West's
operating cost per available seat mile for 1993 was 7.01 cents, which was
approximately 25% lower than the average operating cost per available seat mile
of the nine largest other domestic airlines and was comparable to the costs
incurred by Southwest Airlines, Inc. ("Southwest Airlines"). The Company's
business strategy is to continue to offer competitive fares while maintaining an
incrementally higher level of service relative to low cost carriers generally.
These services include assigned seating, participation in computerized
reservation systems, interline ticketing, first class cabins on certain flights,
baggage transfer and various other services. Management believes that its
principal hub locations in Phoenix and Las Vegas not only provide a low cost
environment for a substantial portion of the Company's operations, but also
position the Company to benefit from an expanding market for leisure travel.
 
     As a part of the Reorganization, the Company entered into certain
agreements (the "Alliance Agreements") with Continental and Mesa. With
Continental, the Company will implement certain code-sharing arrangements,
coordinate certain flight schedules, share ticket counter space, link frequent
flyer programs, and coordinate ground handling operations. With Mesa, America
West modified and extended two code-sharing agreements that establish Mesa as a
feeder carrier for the Company at its hubs in Phoenix and Columbus. The
code-sharing agreements provide for coordinated flight schedules, passenger
handling and computer reservations under the America West flight designator
code, thereby allowing passengers to
 
                                        3

purchase one air fare for their entire trip. Mesa connects 13 cities to the
Company's Phoenix hub, operates under the name "America West Express" and has
begun to incorporate the color scheme and commercial logo of America West on
certain aircraft utilized on these routes. Mesa serves five destinations from
the Company's Columbus mini-hub operations. Management believes the Alliance
Agreements will contribute significantly to the Company's passenger revenue and
operating results.
 
   
     Pursuant to the Reorganization, the Company will substantially reduce its
outstanding debt and increase its liquidity through the infusion of new capital.
In addition, the Company has reached agreements with certain key suppliers of
aircraft. At June 30, 1994, prior to the Reorganization, the Company's long-term
debt including current maturities and estimated liabilities subject to Chapter
11 proceedings aggregated approximately $880 million. Such liabilities at June
30, 1994, adjusted to give pro forma effect to the consummation of the Plan,
would aggregate approximately $638 million.
    
 
   
     Pursuant to the Reorganization, pre-existing equity interests of the
Company will be cancelled, the Company's obligations to other prepetition
creditors will be restructured and general unsecured nonpriority prepetition
creditors ("Prepetition Creditors") will receive, in full satisfaction of their
claims, 25,669,348 shares of Class B Common Stock and $9,828,145 cash. Holders
of the Company's pre-existing common equity interests will receive, on a pro
rata basis, 2,250,000 shares of Class B Common Stock and Warrants to purchase
6,230,769 shares of Class B Common Stock. In addition, pursuant to the exercise
of subscription rights, holders of pre-existing equity interests will receive
1,615,179 shares of Class B Common Stock for an aggregate purchase price of
$14,357,326 ($8.889 per share), including holders of pre-existing preferred
equity interests who will receive 250,000 shares of Class B Common Stock for an
aggregate purchase price of $2,222,250.
    
 
   
     Also pursuant to the Reorganization, the Company will receive approximately
$214.9 million in cash upon the issuance to AmWest Partners, L.P. ("AmWest"),
and to certain assignees of AmWest (as described below), of (i) 1,200,000 shares
of Class A Common Stock, (ii) 13,365,473 shares of Class B Common Stock, (iii)
Warrants to purchase 2,769,231 shares of Class B Common Stock and (iv) $100
million of Senior Notes. Certain funds managed or advised by Fidelity Management
Trust Company and its affiliates (collectively, "Fidelity") and Lehman Brothers
Inc. ("Lehman") will purchase a portion of the Securities that otherwise would
be issued to AmWest pursuant to assignments by AmWest to those parties. Pursuant
to these assignments, Lehman will acquire             shares of Class B Common
Stock and Warrants to purchase             additional shares of Class B Common
Stock in consideration of payment to the Company of approximately $7.7 million,
and Fidelity will acquire        shares of Class B Common Stock, Warrants to
purchase        additional shares of Class B Common Stock and $100 million of
Senior Notes. AmWest is a Texas limited partnership including as investors Mesa,
Continental and TPG Partners, L.P. ("TPG"). TPG is a Delaware limited
partnership which is acquiring aggregate beneficial ownership of      % of the
voting securities of America West. The general partner of AmWest is AmWest
GenPar, Inc., a Texas corporation. The controlling persons of AmWest GenPar also
control TPG. See "Investment Considerations -- Concentration of Voting Power;
Influence of AmWest or its Partners" and "Principal Stockholders." AmWest has
advised the Company that it expects to distribute to its partners the securities
acquired by it pursuant to the Reorganization. Pursuant to the Reorganization,
Lehman, Fidelity and TPG will receive additional shares of Class B Common Stock
for their existing claims and interests. These shares are not subject to the
Registration Statement of which this Prospectus is a part.

                           INVESTMENT CONSIDERATIONS
 
HISTORY OF LOSSES
 
     The Company experienced significant operating losses in each year of the
three year period ended December 31, 1992, and the Company operated as a
debtor-in-possession under Chapter 11 of the federal bankruptcy code from June
27, 1991 to the Effective Date. Although the Company's results of operations
improved in 1993, the airline industry has been extremely competitive and
generally unprofitable in recent years. In the long term, the Company's
viability is dependent upon its ability to sustain profitable results of
operations, and there can be no assurance that such results can be sustained.
 
ADVERSE INDUSTRY CONDITIONS AND COMPETITION
 
     The airline industry is highly competitive. Overall industry profit margins
have traditionally been low and, in each year of the three year period ended
December 31, 1992, were substantially negative. Airlines compete in the areas of
pricing, scheduling (frequency and flight times), on-time performance, frequent
flyer programs and other services. Many of America West's competitors are
carriers with substantially greater financial resources.
 
     The airline industry is susceptible to price discounting, which involves
the offering of discount or promotional fares to passengers. Any such fares
offered by one airline are normally matched by competing airlines, which results
in lower industry yields. In 1992 American Airlines introduced a new fare
structure followed by a deeply discounted summer sale. These steps were
generally matched by other U.S. airlines, including America West, and resulted
in substantially depressed industry yields and significant 1992 losses for most
of the major U.S. airlines. American Airlines and the rest of the domestic
airline industry subsequently abandoned that pricing structure, and fare levels
increased in 1993 from 1992 levels. Nonetheless, significant industry-wide
discounts could be re-implemented at any time, and the introduction of broadly
available, deeply discounted fares by a major U.S. airline would likely result
in lower yields for the entire industry and could have a material adverse effect
on the Company's operating results.
 
     Several of the Company's markets, including those in New York City, Texas,
Southern California, Washington, D.C., Chicago and Las Vegas, are served by
larger carriers and are highly competitive. On many routes, and in particular
those routes between Phoenix and California, fare competition has made it
difficult for the Company to raise fares except on a selective basis. Intense
fare competition with respect to certain markets has adversely affected
passenger yield and, as a result, profitability.
 
     In recent years several new carriers have entered the industry, typically
with low cost structures. Aircraft, skilled labor and gates at most airports
continue to be available to start-up carriers. In some cases, new entrants have
initiated or triggered further price discounting. The entry of additional new
carriers on many of the Company's routes (as well as increased competition from
established carriers) could negatively impact America West's results of
operations.
 
INCREASES IN FUEL PRICES
 
     Fuel costs constituted approximately 14% of America West's total operating
expenses during 1993. A one cent per gallon change in fuel price would affect
the Company's annual operating results by approximately $3 million at present
consumption levels. Accordingly, either a substantial increase in fuel prices or
the lack of adequate fuel supplies in the future would likely have a material
adverse effect on the operations of the Company. Moreover, fuel price increases
or supply shortages, such as those that occurred during the Persian Gulf war,
can occur at any time as a result of, among other things, geopolitical
developments.
 
     The Company purchases fuel on standard trade terms under master agreements
and has been able to obtain fuel sufficient to meet its requirements at
competitive prices. The Company does not currently hedge its fuel costs. In
August 1993, the United States government increased taxes on fuel, including
aircraft fuel, by 4.3 cents per gallon. Airlines are exempt from this tax
increase until October 1, 1995. When implemented, this new tax will increase the
Company's annual operating expenses by approximately $13 million based upon its
 
                                        9
<PAGE>   12
 
1993 fuel consumption levels. There can be no assurance that the U.S. government
will not impose additional taxes on fuel in the future or that such taxes will
not materially affect the Company's results of operations.
 
LEVERAGE
 
     Although the Reorganization will improve the Company's financial position,
the Company will be highly leveraged after the Effective Date. This high degree
of leverage will pose substantial risks to holders of the Securities and could
have a material adverse effect on the marketability, price and future value of
such Securities. This high degree of leverage will increase the reorganized
Company's vulnerability to adverse general economic and airline industry
conditions and to increased competitive pressures.
 
CONCENTRATION OF VOTING POWER; INFLUENCE OF AMWEST AND ITS PARTNERS
 
   
     At the Effective Date, it is anticipated that AmWest and its partners will
own approximately 30.5% of the shares of Class B Common Stock to be outstanding
immediately after the Effective Date and 100% of the Class A Common Stock, and
thereby will control approximately 70.6% of the voting power of America West
(71.4% assuming the exercise of Warrants issued to such holders). As a result,
AmWest or its partners will be able to elect a majority of its designees to the
Board of Directors and otherwise to control the Company by, among other things,
taking or approving actions to (i) amend the America West charter or effect a
merger, sale of assets or other major corporate transaction; (ii) defeat any
takeover attempt; (iii) determine the amount of dividends, if any, paid to
itself and the other holders of Common Stock; and (iv) otherwise control the
outcome of virtually all matters submitted for a vote of the stockholders of the
Company. Two of the partners of AmWest, Mesa and Continental, are engaged in the
airline industry and are parties to certain agreements with the Company. In
addition, the control persons of AmWest GenPar, Inc., the general partner of
AmWest, also control both Air Partners L.P., a special purpose partnership
formed in 1992 to participate in the funding of the reorganization of
Continental and a significant shareholder in Continental, and TPG, a Delaware
limited partnership which is acquiring aggregate beneficial ownership of      %
of the combined voting securities of America West. See "Principal Stockholders."
As a result, there can be no assurance that the interests of Continental, Mesa
or TPG will not differ from the interests of the Company or that either party
will not seek to influence the Company in a manner that serves its interests.
    
 
     Pursuant to the terms of the Stockholders' Agreement among the Company,
AmWest and certain other stockholders or their representatives, AmWest has
agreed to certain limitations on its ability to control the Company, including,
that for a three-year period beginning with the Effective Date, the Company
shall have a 15-member Board of Directors, six members of which may be
designated by parties other than AmWest or its partners (including three
Creditors' Committee Directors, one Equity Committee Director, one Independent
Company Director and one GPA Director, as such terms are defined in the
Stockholders' Agreement). The Stockholders' Agreement also contains other
restrictions on AmWest's ability to effect certain transactions involving the
Company. See "Principal Stockholders -- Stockholders' Agreements."
 
LIMITED TRADING MARKET; SHARES ELIGIBLE FOR FUTURE SALE
 
     There has been no trading market in the Securities prior to the Effective
Date. There can be no assurance regarding the development of an active market
for these Securities. Accordingly, there is no assurance that a holder of such
Securities will be able to sell such Securities in the future or as to the price
at which any such sale may occur. If a market should develop, it is anticipated
that such market may be volatile, at least for an initial period of time after
the Effective Date, and that certain of the recipients of the Securities in the
Reorganization may prefer to liquidate their investments rather than to hold
their investments on a long-term basis.
 
   
     Substantially all of the 43,800,000 outstanding shares of Class B Common
Stock and (assuming no exercise of the outstanding warrants) will be freely
tradeable, subject to certain restrictions with respect to shares held by AmWest
or its partners or assignees. These shares include 14,265,473 shares of Class B
Common Stock to be issued to the Selling Securityholders that are covered by the
Registration Statement of which this Prospectus is a part, 25,669,348 shares of
Class B Common Stock to be distributed to prepetition creditors and 2,250,000
shares of Class B Common Stock to be issued to pre-existing common equity
holders. In addition, at the Effective Date, the Company will issue Warrants to
purchase 10,384,615 shares of Class B
    
 
                                       10
<PAGE>   13
 
Common Stock. The Warrants will be immediately exercisable, and the Company
believes that substantially all of the shares of Class B Common Stock issuable
upon such exercise will be freely tradeable.
 
LIMITATION ON VOTING BY FOREIGN OWNERS
 
     The Company's Restated Certificate of Incorporation provides that no more
than 25% of the voting interest of the Company may be owned or controlled by
persons who are not U.S. citizens and that the voting rights of such persons are
subject to automatic suspension to the extent required to ensure that the
Company is in compliance with applicable laws relating to ownership or control
of a U.S. carrier. United States law currently requires that no more than 25% of
the voting stock of the Company (or any other domestic airline) may be owned
directly or indirectly by persons who are not citizens of the United States. See
"Description of Capital Stock -- Limitation on Voting by Foreign Owners."
 
LABOR NEGOTIATIONS
 
   
     The Company historically has operated without collective bargaining
agreements covering any of its employees. In October 1993, however, the Air Line
Pilots Association ("ALPA") was certified as the bargaining representative of
the Company's flight deck crew members, and formal negotiations of a collective
bargaining agreement have commenced. In addition, elections will be held during
September, 1994 on a proposal by the Association of Flight Attendants ("AFA") to
represent the Company's customer service representatives and the Company
anticipates that an election will be held during 1994 with respect to a proposal
by the Transportation Workers Union ("TWU") to represent the Company's fleet
service personnel. On August 1, 1994 the International Brotherhood of Teamsters
(the "Teamsters") filed an application to represent the Company's mechanics and
related personnel. The Company cannot predict whether either the AFA, TWU or the
Teamsters will be certified to represent any of the Company's employees.
Furthermore, there can be no assurance that a future collective bargaining
agreement with any of the ALPA, AFA or TWU will not contain wage increases, work
rules or other provisions that could materially affect the Company's operations
or financial performance. See "Business -- Employees."
    
 
GOVERNMENT REGULATION
 
     The Company is subject to the Federal Aviation Act of 1958, as amended (the
"Aviation Act"), under which the Department of Transportation (the "DOT") and
the Federal Aviation Administration (the "FAA") exercise regulatory authority.
This regulatory authority includes (i) the determination and periodic review of
the fitness (including financial fitness) of air carriers; (ii) the
certification and regulation of the flight equipment; (iii) the approval of
personnel who may engage in flight, maintenance and operations activities; and
(iv) the approval of flight training activities and the enforcement of minimum
air safety standards set forth in FAA regulations. In accordance with the
Airline Deregulation Act of 1978, domestic airline fares and routes are no
longer subject to significant regulation. The DOT maintains authority over
international aviation, subject to review by the President of the United States,
and has jurisdiction over consumer protection policies, computer reservation
system issues and unfair trade practices.
 
     In the last several years, the FAA has issued a number of maintenance
directives and other regulations relating to, among other things, retirement of
older aircraft, collision avoidance system, airborne windshear avoidance
systems, noise abatement and increased inspections and maintenance procedures to
be conducted on older aircraft. Additional laws and regulations have been
proposed from time to time which could significantly increase the cost of
airline operations by imposing additional requirements or restrictions on
operations. Laws and regulations have been considered from time to time that
would prohibit or restrict the ownership and transfer of airline routes or
slots. There is no assurance that laws and regulations currently enacted or
enacted in the future will not adversely affect the Company's ability to
maintain its current level of operating results. See "Business -- Government
Regulations."

FUTURE CAPITAL REQUIREMENTS
 
   
     After giving effect to the Reorganization on a pro forma basis, as of June
30, 1994, America West had $638.4 million of long-term indebtedness (including
current maturities) and $587.5 million of stockholders' equity. As of such date,
the Company had $284.9 million of cash and cash equivalents on a pro forma
basis. America West does not have available lines of credit or significant
unencumbered assets. America West is more leveraged and has significantly less
liquidity than certain of its competitors, several of whom have available lines
of credit or significant unencumbered assets. Accordingly, the Company may be
less able than certain of its competitors to withstand a prolonged economic
recession.
    
 
     As of June 30, 1994, the Company had significant capital commitments,
including firm commitments and options for a substantial number of new aircraft
with a cost aggregating approximately $2.7 billion, a total which is subject to
change pending the outcome of current negotiations. Upon the Effective Date, the
Company will have an obligation to lease up to eight aircraft pursuant to put
rights held by a third party. The Company will require substantial capital from
external sources to meet these financial commitments. The Company has no current
financing arrangements for most of its aircraft purchase commitments and intends
to seek additional financing (which may include public debt financing or private
financing) in the future when and as appropriate. There can be no assurance that
sufficient financing will be obtained for all aircraft and other capital
requirements. A default by the Company under any such commitment could have a
material adverse effect on the Company.
 
   
INDEPENDENT AUDITOR'S REPORT ON FINANCIAL STATEMENTS
    
 
   
     The reports of the Company's independent certified public accountants
covering the December 31, 1993 financial statements and schedules contain an
explanatory paragraph that states that the Company's Chapter 11 proceeding,
significant losses, accumulated deficit and highly leveraged capital structure
raise substantial doubt about its ability to continue as a going concern. The
financial statements and schedules do not include any adjustments that might
result from the outcome of these uncertainities. These reports do not cover the
pro forma financial statements included elsewhere in this Prospectus and,
accordingly, do not address the impact of consummation of the Plan on the
Company.

                                  THE COMPANY
 
GENERAL
 
   
     America West is a major United States air carrier providing passenger,
cargo and mail service, with its primary markets in the western and southwestern
regions of the United States. The Company operates its route system through two
principal hubs, Phoenix, Arizona and Las Vegas, Nevada, and a mini-hub in
Columbus, Ohio. As of July 31, 1994, America West operated a fleet of 85 jet
aircraft and provided service to 45 destinations. Through alliances with Mesa,
the Company provides connecting service to an additional 18 destinations. The
Company also has formed an alliance with Continental to serve additional
destinations.
    
 
     America West currently operates with one of the lowest cost structures
among the major U.S. airlines, based on reported 1993 results. America West's
operating cost per available seat mile for 1993 was 7.01 cents, which was
approximately 25% lower than the average operating cost per available seat mile
of the nine largest other domestic airlines and was comparable to the costs
incurred by Southwest Airlines. The Company's business strategy is to continue
to offer competitive fares while maintaining an incrementally higher level of
service relative to low cost carriers generally. These services include assigned
seating, participation in computerized reservation systems, interline ticketing,
first class cabins on certain flights, baggage transfer and various other
services. Management believes that its principal hub locations in Phoenix and
Las Vegas not only provide a low cost environment for a substantial portion of
the Company's operations, but also position the Company to benefit from an
expanding market for leisure travel.
 
     The Company's principal offices are located at 4000 East Sky Harbor
Boulevard, Phoenix, Arizona 85034. The Company's telephone number is (602)
693-0800.
 
BACKGROUND TO THE REORGANIZATION
 
     America West commenced operations in 1983 with three aircraft serving four
destinations from Phoenix, Arizona. America West's original route structure
consisted primarily of shorter-haul routes in the southwestern market, which
brought it into direct competition with certain low fare airlines, particularly
Southwest Airlines. Throughout the 1980s, America West financed rapid expansion
of its fleet, with corresponding significant increases in debt and lease
obligations. In addition, in the late 1980s, the Company entered the long-haul
and, on a very limited basis, international markets. The Company introduced
several aircraft types into its fleet in order to pursue this strategy. By July
1991, the Company operated a fleet of 123 aircraft serving 54 destinations in
the continental United States, Hawaii, Canada and Japan.
 
     The Company experienced a significant net loss for the last six months of
1990, as revenues were lower than anticipated and fuel costs were higher than
anticipated. The Persian Gulf conflict, which began in August of 1990, the fear
of terrorism and the deepening national recession produced depressed traffic
levels, higher fuel prices and fierce price competition in the airline industry.
Beginning in February 1991, the Company undertook a series of actions designed
to improve its cash position and reduce costs, including significant fare
promotions and pay reductions. In June 1991, however, the Company faced a severe
liquidity crisis and filed for protection under Chapter 11 of the United States
Bankruptcy Code.
 
     During the bankruptcy case, the Company operated as a debtor-in-possession
and implemented an operational restructuring pursuant to which it has:
 
   
     - Reduced its fleet size from 123 aircraft in July 1991 to 85 at July 31,
       1994, facilitating a better matching of capacity to demand through
       elimination of nonproductive routes.
    
 
     - Reduced the aircraft types operated from five to three, resulting in
       reduced operating costs, including those related to maintenance, training
       and parts inventories.
 
     - Implemented certain enhancements to its revenue management system to
       optimize the level of passenger revenues generated on each flight.
 
     - Eliminated Company operated commuter service and introduced code-sharing
       agreements to expand the Company's scope of service and attract a broader
       passenger base.
 
                                       13
<PAGE>   16
 
   
     - Implemented numerous cost reduction programs, including a Company-wide
       pay reduction in August 1991 and reduction of aircraft lease rentals to
       fair market rates in the summer of 1992.
    
 
     These programs, combined with a gradually improving economic climate and a
more stable environment relative to fare competition within the airline
industry, enabled the Company to realize operating income of $121.1 million in
1993, compared to operating losses of $74.8 million and $104.7 million for 1992
and 1991, respectively.
 
THE PLAN OF REORGANIZATION
 
   
     On August 10, 1994, the order of the Bankruptcy Court confirming the Plan
became final. The Plan will be consummated on the Effective Date when certain
conditions specified in the Plan are satisfied or waived. The Company expects
that the Effective Date will occur on or about August   , 1994.
    
 
     Pursuant to the Plan, after giving effect to various elections made by
general unsecured creditors and the exercise of certain subscription rights by
certain holders of pre-existing equity interests, the following will occur upon
the Effective Date:
 
   
     - AmWest (together with Lehman and Fidelity, as assignees of AmWest) will
       invest $214.9 million in consideration for the issuance of securities by
       the Company, consisting of (i) 1,200,000 shares of Class A Common Stock
       at a price of $7.467 per share; (ii) 13,365,473 shares of Class B Common
       Stock, including 12,259,821 shares at a price of $7.467 per share and
       1,105,652 shares at $8.889 per share (representing shares acquired as a
       result of cash elections made by unsecured creditors as described below);
       (iii) 2,769,231 Warrants to purchase shares of Class B Common Stock; and
       (iv) $100 million principal amount of Senior Notes.
    
 
   
     - The general unsecured creditors of the Company will be issued an
       aggregate of 25,669,348 shares of Class B Common Stock and cash
       aggregating $9,828,145 (such cash representing $8.889 per share paid to
       unsecured creditors electing to receive cash in lieu shares of Class B
       Common Stock).
    
 
   
     - Holders of preferred equity interests of the Company prior to the
       Reorganization will receive their pro rata share of (i) $500,000 and (ii)
       250,000 shares of Class B Common Stock (representing shares acquired
       pursuant to certain subscription rights at a price of $8.889 per share).
    
 
   
     - Holders of common equity interests in the Company prior to the
       Reorganization will be issued 3,615,179 shares of Class B Common Stock
       (1,365,179 of which shares are to be issued in exchange for cash,
       aggregating $12,135,076, provided by such equity holders upon the
       exercise of rights to subscribe for such shares at a price of $8.889 per
       share), and will receive 6,230,769 Warrants to purchase shares of Class B
       Common Stock.
    
 
   
     - In exchange for certain concessions principally arising from cancellation
       of the right of Guinness Peat Aviation ("GPA") affiliates to put to
       America West 10 Airbus A320 aircraft at specified rates, GPA, or certain
       affiliates thereof, will receive (i) 900,000 shares of Class B Common
       Stock; (ii) 1,384,615 Warrants; (iii) a cash payment of approximately
       $30.5 million; (iv) the right to require the Company to lease up to eight
       aircraft of types operated by the Company on terms that the Company
       believes to be more favorable than those currently applicable to the put
       aircraft, which right must be exercised prior to June 30, 1999; and (v)
       the right to designate one director of the Company.
    
 
     - Approximately $77.6 million of debtor-in-possession ("D.I.P.") financing
       will be repaid in full in cash.
 
     - Continental, Mesa and America West will enter into certain Alliance
       Agreements relating to code-sharing, schedule coordination and certain
       other relationships and agreements.
 
     - The Company's Board of Directors will be reconstituted to include 15
       members, of which nine shall be designated by AmWest, three shall be
       designated by the Official Committee of Unsecured Creditors (the
       "Creditors' Committee") and one shall be designated by each of the
       Official Committee of Equity Security Holders (the "Equity Committee"),
       GPA and the pre-Reorganization Board of Directors.
 
                                       14
<PAGE>   17
 
     - The Plan also provides for many other matters, including the satisfaction
       of certain other prepetition claims in accordance with negotiated
       settlement agreements, the disposition of the various types of claims
       asserted against the Company, the adherence to the Company's aircraft
       lease agreements, the amendment of the Company's aircraft purchase
       agreements and release of the Company's employees from all currently
       existing obligations arising under the Company's stock purchase plan in
       consideration for the cancellation of the shares of Company stock
       securing such obligations.
 
     The foregoing is a summary of the material aspects of the Plan. A complete
copy of the Plan has been filed as an exhibit to the Registration Statement.
 
                                USE OF PROCEEDS
 
     The Company will not receive any proceeds from the sale of the Securities
by the Selling Securityholders.
 
                                DIVIDEND POLICY
 
     The Company does not anticipate paying cash dividends in the foreseeable
future. The Company expects that it will retain all available earnings generated
by the Company's operations for the development and growth of its business. Any
future determination as to the payment of dividends will be made in the
discretion of the Board of Directors of the Company and will depend upon the
Company's operating results, financial condition, capital requirements, general
business conditions and such other factors as the Board of Directors deems
relevant. The Company expects that certain loan agreements including the
Indenture covering the Senior Notes will restrict the payment of cash dividends
on the Common Stock under certain circumstances. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."

     The following table sets forth the unaudited capitalization of the Company
at June 30, 1994, and as adjusted to give pro forma effect to the consummation
of the Plan at that date. The presentation does not purport to represent what
the Company's actual capitalization would have been had such transactions in
fact been consummated on such date. The table should be read in conjunction with

                            SELECTED FINANCIAL DATA
 
     The selected data presented below under the captions "Statement of
Operations Data" and "Balance Sheet Data" for, and as of the end of, each of the
years in the five-year period ended December 31, 1993, are derived from the
financial statements of the Company, which financial statements have been
audited by KPMG Peat Marwick, independent certified public accountants. The
financial statements as of December 31, 1993 and 1992, and for each of the years
in the three-year period ended December 31, 1993, and the report thereon, are
included elsewhere in this Prospectus.
 
   
     The selected data should be read in conjunction with the financial
statements for the five-year period ended December 31, 1993, the related notes
and the independent auditors' report, which contains an explanatory paragraph
that states that the Company's Chapter 11 proceeding, significant losses,
accumulated deficit and highly leveraged capital structure raise substantial
doubt about its ability to continue as a going concern, appearing elsewhere in
this Prospectus. The financial statements and the selected data do not include
any adjustments that might result from the outcome of these uncertainties. As a
result of the Company filing a voluntary petition to reorganize under Chapter 11
of the U.S. Bankruptcy Code on June 27, 1991 and operating as a
debtor-in-possession thereafter, the selected financial data for periods prior
to June 27, 1991 are not comparable to periods subsequent to such date. The
selected data presented below for the six-month periods ended June 30, 1994 and
1993 and as of June 30, 1994 are derived from the unaudited condensed financial
statements of the Company included elsewhere in this Prospectus.

(a) Includes extraordinary items of $2,024,000 in 1990 resulting from the
    purchase and retirement of convertible subordinated debentures and, in 1989,
    income tax benefits resulting from the utilization of net operating loss
    carryforwards amounting to $7,215,000.
 
(b) For purposes of computing the ratio of earnings to fixed charges, "earnings"
    consist of income (loss) before taxes and extraordinary items plus fixed
    charges less capitalized interest. "Fixed charges" consist of interest
    expense including amortization of debt issuance cost, capitalized interest
    and a portion of rent expense which is deemed to be representative of an
    interest factor. For the years ended December 31, 1992, 1991 and 1990,
    earnings were insufficient to cover fixed charges by $131,761,000,

          NOTES TO UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS
 
   
     The following notes set forth the explanations and assumptions used and
adjustments made in preparing the unaudited pro forma condensed balance sheet as
of June 30, 1994, and the unaudited pro forma condensed statements of operations
for the year ended December 31, 1993 and for the six months ended June 30, 1994.
    
 
   
     The unaudited pro forma condensed financial statements reflect the
adjustments described under "Pro Forma Adjustments" below, which are based on
the assumptions and preliminary estimates described therein, which are subject
to change. These statements do not purport to be indicative of the financial
position and results of operations of America West as of such dates or for such
periods, nor are they indicative of future results. Furthermore, these unaudited
pro forma condensed financial statements do not reflect anticipated changes
which may occur as the result of activities before and after the Effective Date
of the Plan and other matters. (For the purposes of the pro forma financial
statements, the "Effective Date" is assumed to be June 30, 1994 for the pro
forma balance sheet, and January 1, 1993 for the pro forma statements of
operations.)
    
 
     The unaudited pro forma condensed financial statements should be read in
conjunction with the financial statements and the notes thereto included
elsewhere in this Prospectus.
 
PRO FORMA ADJUSTMENTS
 
     The unaudited pro forma condensed balance sheet and unaudited pro forma
condensed statements of operations reflect the following pro forma adjustments
based on the assumptions described below:
 
     Balance Sheet Pro Forma Adjustments
 
     1. To record the effects of the consummation of the Plan:
 
   
          a. Estimated additional liabilities from settlement of certain claims;
     payment of certain claims; issuance of new debt to settle claims;
     cancellation of liabilities subject to Chapter 11 proceedings; and accrual
     and payment for reorganization expenses including success bonuses;
    
 
   
          b. Repayment of the debtor-in-possession loan;
    
 
          c. Forgiveness of employee notes receivable and the write-off of
     related deferred compensation under employee stock purchase plans.
 
          d. Issuance of Class A and Class B Common Stock to AmWest and its
     assignees for gross proceeds of $114.9 million and to settle claims; and
     record equity value of the reorganized Company;
 
   
          e. Issuance of $100 million of       % Senior Notes, including
     estimated fees and issuance costs of $1 million; and
    
 
   
          f. Cancellation of all pre-existing ownership interests and
     elimination of the accumulated deficit.
    
 
     2. To record the release of restricted cash and holdbacks related to credit
card transactions.
 
     3. To record estimated "fresh start" adjustments pursuant to Statement of
Position 90-7, Financial Reporting by Entities in Reorganization under the
Bankruptcy Code ("SOP 90-7"), issued by the American Institute of Certified
Public Accountants:
 
   
          a. Adjusting assets and liabilities to fair market value. Such fair
     market values were estimated by America West's management based on its
     reviews of various appraisals performed on certain of its owned facilities,
     aircraft, rotable spare parts (including spare engines) and flight
     simulators; and on management's estimates as to the fair values for other
     of its fixed assets such as ground support, maintenance and other
     equipment. Additionally, such estimated market values (including the fair
     market lease rates for leased aircraft) are deemed to reflect the fair
    
     market values of those assets, and certain other intangible
 
                                       22
<PAGE>   25
 
                          AMERICA WEST AIRLINES, INC.
 
   NOTES TO UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS -- (CONTINUED)
 
   
     assets and liabilities (i.e., deferred heavy aircraft maintenance and other
     aircraft-related maintenance accruals, leasehold improvements, deferred
     manufacturers' and other credits, and rent leveling provisions) are assumed
     to be written off at the Effective Date. America West has engaged
     independent parties to prepare valuations of certain of its fixed assets
     and leased aircraft rental rates. Based on the results of these valuations,
     these fair market values and lease rates will be adjusted accordingly.
    
 
          b. Adjusting operating leases (principally aircraft operating leases)
     to fair market lease rates; and
 
          c. Recording reorganization value in excess of amounts allocable to
     identifiable assets ("Excess Reorganization Value"). The reorganization
     value of America West at the Effective Date is based on a valuation
     analysis prepared by an independent third party. This valuation is, in
     turn, based on, among other considerations: historical financial results of
     America West, financial projections of America West through 1997 prepared
     by management, multiples based on a comparison of qualitative and
     quantitative data for selected publicly-traded companies engaged in
     businesses comparable to the business of America West, certain economic and
     industry information relevant to the business of America West and
     discussions with management regarding the current operations and prospects
     of America West. Many of the analytical assumptions upon which this
     valuation is based are beyond the control of America West and there may be
     material variations between such assumptions and the actual facts.
 
     Statements of Operations Pro Forma Adjustments
 
   
     4. To eliminate reorganization expense, net. Reorganization costs incurred
subsequent to the Effective Date and not accrued at the Effective Date will be
reflected as reorganization expenses in the statement of operations in the
succeeding period.
    
 
   
     5. To record interest expense and amortize debt issuance costs for the
Senior Notes, assuming an interest rate of 11.5%, and to adjust interest expense
for the payoff of the D.I.P. loan and the amortization of certain debt, given
that all such transactions began at the Effective Date.
    
 
     6. To adjust lease rent expense (principally aircraft operating leases) to
fair market rents.
 
     7. To adjust depreciation and amortization to be reflective of pro forma
balance sheet amounts:
 
   
          a. Amortization of Excess Reorganization Value of approximately $697
     million on a straight-line basis over a period of 20 years, and subject to
     certain adjustments as discussed at note 9 below; and
    
 
          b. Reduced depreciation and amortization primarily due to the
     write-down of fixed assets to fair value.
 
   
     8. To reclass interest income recorded previously as offsets to
Reorganization expenses and record interest income on additional cash and cash
equivalents due to the consummation of the Plan.
    
 
     9. To adjust income tax expense for the effects of the consummation of the
Plan, including limitations on the uses of net operating loss carryforwards due
to a statutory ownership change. Pro forma tax expense exceeds the U.S.
statutory tax rate of 35% primarily as a result of amortization of Excess
Reorganization Value and state and local taxes.
 
     It is estimated that the Company will have available at the consummation of
the Plan net future deductible temporary differences, primarily net operating
loss carryforwards. These deferred tax benefits have not been reflected in the
accompanying pro forma balance sheet. The realization of these benefits on a pro
forma basis are reported as a reduction in Excess Reorganization Value rather
than as a reduction in the tax provision in the statements of operations.

   NOTES TO UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The analysis of the impact of the consummation of the Plan on the provision
for income taxes has not been finalized. When such analysis is completed, the
actual results could differ from the estimates included in the pro forma
financial statements.
 
     10. Pro forma earnings per share have been computed based on the estimated
weighted average number of common shares outstanding during the applicable
period assuming that the Plan was effective on January 1, 1993. However, since
the exercise price of the Warrants will not be determined until a later date,
the earnings per share computation is presented without the effect of the
exercise of the Warrants for both primary and fully diluted earnings per share.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
   
ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS.
    
 
   
     On August 10, 1994, the United States Bankruptcy Court for the District of
Arizona (the "Bankruptcy Court") confirmed the Company's Plan of Reorganization
(the "Plan"). The Company currently anticipates that the Plan will be effective
after expiration of the Bankruptcy Code 10-day appeal period, on or about August
23, 1994 (the "Effective Date").
    
 
   
     In connection with the confirmation hearing on August 10, 1994, the Company
filed certain motions with the Bankruptcy Court to secure approval to pay the
following confirmation bonuses or success fees:
    
 
   
     -- $9.3 million to be paid based upon length of service to non-officer
        employees.
    
 
   
     -- $1.2 million to be paid to officers and other members of management.
    
 
   
     -- 125,000 shares of stock in the reorganized Company to be issued to the
        Company's Chairman and Chief Executive Officer.
    
 
   
     A hearing on these motions has been scheduled for August 24, 1994.
    
 
   
     On June 27, 1991 the Company filed a voluntary petition in the United
States Bankruptcy Court for the District of Arizona (the "Bankruptcy Court") to
reorganize under Chapter 11 of the United States Bankruptcy Code (the
"Bankruptcy Code"). The Company operated as a debtor-in-possession ("D.I.P.")
under the supervision of the Bankruptcy Court until the Effective Date of the
Plan.
    
 
     Due to the bankruptcy case, current economic conditions and the competitive
nature of the airline industry, no measure of comparability can be drawn from
past results in order to measure those that may occur in the future. Among the
uncertainties which have affected the Company's operations in the past and might
adversely impact the Company's future operations are (i) general economic
conditions; (ii) changes in the cost of fuel, labor, capital and other operating
items; (iii) increased level of competition resulting in significant discounting
of fares; and (iv) changes in capacity, load factors and yields or reduced
levels of passenger traffic due to war or terrorist activities.
 
     On the Effective Date of the Plan, America West will adopt fresh start
reporting in accordance with SOP 90-7, resulting in adjustment of the Company's
common stockholders' equity and the carrying values of assets and liabilities.
Accordingly, the Company's post-reorganization balance sheet and statement of
operations will not be prepared on a consistent basis of accounting with the
pre-reorganization balance sheet and statements of operations. In connection
with the Reorganization, the Company will receive a significant capital
infusion, a substantial amount of prepetition liabilities will be converted to
equity or otherwise discharged and significant adjustments will be made to
reflect the resolution of or provision for certain contingent liabilities.
 
IMPACT OF FRESH START REPORTING ON RESULTS OF OPERATIONS
 
     The fresh start reporting adjustments, primarily related to the adjustment
of the Company's assets and liabilities to fair market values, will have a
significant effect on the Company's future operating results. The more
significant adjustments relate to decreased depreciation expense, increased
amortization expense relating to reorganization value in excess of amounts
allocable to identifiable assets, reduced aircraft rent expense and increased
interest expense.
 
RESULTS OF OPERATIONS
 
   
     For the Six Months Ended June 30, 1994 as Compared to the Six Months Ended
June 30, 1993
    
 
   
     For the six months ended June 30, 1994, the Company realized a net income
of $35.3 million ($1.30 per common share on a primary basis) compared to $12.4
million ($.52 per common share on a primary basis) for
    
 
                                       25
<PAGE>   28
 
   
the comparable period of 1993. The results for the six months include
Reorganization expenses of $18.3 million and $1.9 million for 1994 and 1993,
respectively. The continuation of the positive trend in operating results, which
commenced during the fourth quarter of 1992, is attributable to several factors
which include improved economic and competitive fare conditions, the
stabilization of fuel prices as well as the benefits derived from the reduction
in fleet size from 104 aircraft to 85 aircraft, the implementation of numerous
cost reduction and revenue enhancement programs, the elimination of the
Company's commuter operation and the introduction of code sharing agreements.
    
 
   
     Passenger revenues for the six months ended June 30, 1994 increased 10.1%
to $665.0 million compared to the 1993 period. Although average passenger yield
declined by 4.6% during the period, RPMs increased by 15.3% more than offsetting
the decline in yield. Passenger revenues per ASM increased 5.9% to 7.55 cents
for the six months of 1994 on the strength of the increase in revenue passenger
miles.
    
 
   
     Revenues from sources other than passenger fares increased during the first
six months of 1994 to $43.6 million compared to $37.7 million for 1993. This
improvement of 16% was due primarily to increases in freight and mail revenues.
    
 
   
     The following table details certain key operating statistics for the six
month periods ended June 30, 1994 and 1993.

</TABLE>
    
 
     The changes in the components of operating expense per ASM between 1994 and
1993 are explained as follows:
 
   
     -- For the six month period of 1994 salaries and related costs have
        increased primarily due to performance and employment award
        distributions under the transition pay program which was instituted in
        the second quarter of 1993 and the new pay program instituted in the
        second quarter of 1994.
    
 
   
     -- Rentals and landing fees decreased due to the reduction in airport rent
        expense at New York's JFK and Phoenix's Sky Harbor International and the
        return of certain administrative office space, as part
    
 
                                       26
<PAGE>   29
 
   
        of the Company's facilities consolidation program. In addition, rentals
        and landing fees have decreased for the first six months of 1994
        compared to the 1993 period due to the return of a wet leased aircraft
        that serviced the Hawaii market through March 31, 1993.
    
 
   
     -- Aircraft fuel expense decreased due to the decline in the average price
        per gallon to 53.66 cents in 1994 from 62.87 cents for 1993.
    
 
   
     -- The increase in the level of agency commission expense is primarily due
        to the significant increase in passenger revenue per ASM from 7.13 cents
        for 1993 to 7.55 cents for 1994.
    
 
   
     -- The level of aircraft maintenance materials and repairs expense has
        increased primarily as a result of higher aircraft utilization. Average
        daily utilization of the aircraft fleet has increased from 10.7 hours
        per day for 1993 to 11.1 hours per day for 1994. This higher level of
        utilization has resulted in increases to engine and engine component
        repair expense and to increases in line maintenance materials usage.
    
 
   
     -- The increase in depreciation and amortization expense is primarily
        attributable to increased heavy engine overhauls on a scheduled basis.
    
 
   
     -- The increase in other operating expenses of 13% is primarily due to
        increased media advertising costs as well as expenses related to
        increased traffic such as credit card discount fees, booking fees,
        telephone charges, catering expenses and single/multiple use supplies.
    
 
   
     Non-operating expenses (net of non-operating income) amounted to $45.1
million and $29.7 million for 1994 and 1993, respectively. Interest expense for
1994 was $26.1 million, slightly below the $27.6 million for the same period of
1993. In conformity with SOP 90-7, the Company has ceased accruing and paying
interest on unsecured pre-petition long-term debt. Interest expense for 1994
would have been $33.9 million, if the Company had continued to accrue interest
on such debt.
    
 
   
     During the first six months, the Company incurred expenses of $18.3 million
in 1994 and $1.9 million in 1993 in connection with the Reorganization. Such
expenses for 1994 include increased professional fees and charges of $7.5
million related to the termination of the Kawasaki Put Agreement and the
settlement of an administrative claim. Reorganization related expenses are
expected to significantly affect future results.
    
 
   
     Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109 "Accounting for Income Taxes," (SFAS 109). Since
there was no cumulative effect of this change in accounting method, prior year
financial statements have not been restated.
    
 
   
     For the Years Ended December 31, 1993, 1992 and 1991
    
 
     The Company realized net income of $37.2 million ($1.50 per common share)
for 1993 compared to net losses of $131.8 million ($5.58 per common share) and
$222 million ($10.39 per common share) for 1992 and 1991, respectively. The
results for 1993 include reorganization expenses of $25 million and losses
aggregating $4.6 million primarily resulting from the disposition of surplus
spare aircraft parts and equipment. During 1992, the Company recorded
restructuring charges of $31.3 million, reorganization expenses of $16.2 million
and a gain of $15 million from the sale of its Honolulu to Nagoya, Japan route,
while the 1991 results were affected by reorganization expenses of $58.4
million. The Company was only one of two major U.S. airlines to report a profit
in each quarter of 1993.

     The Company began to realize significant improvement in its operating
results commencing the fourth quarter of 1992. During 1993, the level of
operating income improved each quarter as shown in the table below.

</TABLE>
 
     The improvement in operating results for 1993 compared to 1992 and 1991 is
attributable to several factors, the most significant of which are noted below.
 
     -- A gradually improving economic climate, and a more stable environment
        relative to fare competition within the airline industry.
 
     -- The reduction in fleet size from 123 aircraft in July 1991 to the
        current fleet of 85 aircraft has facilitated a better matching of
        capacity to demand. In addition, the consolidation of the fleet from
        five to three aircraft types has enabled the Company to further reduce
        its level of costs including those related to maintenance, training and
        inventories of parts.
 
     -- In addition to reducing or eliminating certain routes as part of the
        aircraft fleet downsizing, the Company implemented certain enhancements
        to its revenue management system in an effort to optimize the level of
        passenger revenues generated on each flight. Such enhancements enable
        the Company to more effectively allocate seats within various fare
        categories.
 
     -- The implementation of numerous cost reduction programs since 1991,
        including a Company-wide pay reduction in August of 1991 and reductions
        of aircraft lease rentals to fair market rates in the fall of 1992.
 
     -- The elimination of the Company's commuter operation and the introduction
        of three code-sharing agreements have enabled the Company to expand its
        scope of service and attract a broader passenger base.
 
     The effect of these programs and the other factors described above resulted
in operating income of $121.1 million for 1993, compared to operating losses of
$74.8 million and $104.7 million for 1992 and 1991, respectively.
 
     Total operating revenues were $1.3 billion in 1993, an increase of 2.4%
compared to the prior year and 6.3% less than 1991, primarily due to the
significant reduction in capacity. On April 1, 1993, the Company ceased service
to Hawaii. Passenger revenues for 1993, 1992 and 1991 were $1.2 billion, $1.2
billion and $1.3 billion, respectively. Summarized below are certain capacity
and traffic statistics for the years ended December 31, 1993, 1992 and 1991 and
the percentage change in such statistics from 1991 and 1992, respectively, to
1993.

     In spite of the significant decline in capacity in 1993 compared to the two
previous years, passenger revenues per ASM improved by 15.1 percent and 12.2
percent compared to 1992 and 1991, respectively. This improvement was primarily
attributable to the combination of the following factors.
 
     -- An improved climate relative to the economy and industry fare
        competition.
 
     -- The reduction in aircraft fleet size in conjunction with the
        implementation of enhancements to the Company's revenue management
        systems.
 
     -- The elimination of "fare simplification" in 1993 and 50 percent-off
        sales that occurred on an industry-wide basis in the second and third
        quarters of 1992.
 
     -- The 50 percent-off sale conducted by the Company on a system-wide basis
        in February 1991.
 
     Revenues from sources other than passenger fares decreased during 1993 to
$78.8 million compared to $79.3 million and $81.7 million for 1992 and 1991,
respectively. Freight and mail revenues comprised 51.0%, or $40.2 million, of
other revenues for 1993. This represents a decrease of 4.6% compared to 1992 and
8.0 percent compared to 1991. For the years 1993, 1992 and 1991, the Company
carried 110.7 million, 116.4 million and 119.8 million pounds of freight and
mail, respectively. The decline in freight and mail revenues during the last
three years is a direct result of capacity reductions, the most significant of
which relate to the cessation of service to Hawaii and Nagoya, Japan. The
balance of other revenues includes revenues generated from pilot training,
contract services provided to other airlines for maintenance and ground
handling, reduced rate fares, alcoholic beverage and headset sales, and service
charges assessed for refunds, reissues and prepaid ticket advices.
 
     In spite of the significant reductions in capacity which have occurred
since the filing for protection under Chapter 11, operating expense per ASM has
declined to 7.01 cents for 1993 from 7.10 cents for 1992 and 7.36 cents for
1991. The table below sets forth the major categories of operating expense per
ASM for 1993, 1992 and 1991 and the percentage change in such expenses from 1991
and 1992, respectively, to 1993:

     The changes in the components of operating expense per ASM should be
considered in relation to the decline in available seat miles of 10.8% and 16.7%
from 1992 and 1991, respectively, and are explained as follows:
 
     -- The 6.0% increase in salaries and related costs compared to 1992 is a
        result of the decline in capacity as well as the implementation of a
        transition pay program in the second quarter of 1993. The transition pay
        program was designed to restore a portion of the 10% wage reduction that
        was effected Company-wide on August 1, 1991 (officers and other
        management personnel received wage reductions of 10% to 25% commencing
        in February 1991). The program, which was in effect for four fiscal
        quarters, provided for the following payments on a quarterly basis to
        all active employees during the quarter.

             distributions were made based upon the Company meeting or exceeding
             its operating income target for a given quarter as incorporated in
             its business plan. The aggregate award for 1993 amounted to
             approximately $6.5 million including applicable payroll taxes.
 
          b. Commencing the third quarter of 1993, employment award
             distributions were made based on the greater of .5 percent of an
             employee's annual base wage, or $125, whichever is higher, on a
             quarterly basis. The aggregate award for 1993 amounted to
             approximately $2.6 million including applicable payroll taxes.
 
     The favorable variance compared to the 1991 level was primarily
attributable to the reduction in payroll costs related to the decline in
capacity as well as overhead and the Company-wide wage reduction instituted in
August 1991.
 
     -- Rentals and landing fees decreased due to the reduction in fleet size to
        85 aircraft as well as the reduction in rental rates to fair market
        rates for certain aircraft commencing in August 1992 for a period of two
        years.
 
     -- Aircraft fuel decreased due to the decline in the average price per
        gallon to 61.05 cents from 62.70 cents for 1992 and 67.10 cents for
        1991.
 
     -- The increase in the level of agency commission expense is primarily due
        to the significant increase in passenger revenue per ASM from 6.30 cents
        and 6.46 cents for 1992 and 1991, respectively, to 7.25 cents for 1993.
 
     -- The decrease in aircraft maintenance materials and repairs is primarily
        due to the change in the composition of the aircraft fleet.
 
     -- Restructuring charges incurred in 1992 consisted of the following:

     The restructuring charges were necessitated by aircraft fleet reductions
and other operational changes. The Company reduced its fleet to 87 aircraft at
the end of 1992, as well as eliminated two of five aircraft types it operated.
Additionally, employee headcount was reduced by approximately 1,500 employees
and service was terminated to ten cities through the end of 1992.
 
     -- The increase in depreciation and amortization is primarily attributable
        to increased heavy engine overhauls.
 
   
     -- Other operating expenses decreased 7.1 percent compared to 1992 and was
        lower by 18.9% compared to 1991. The decrease compared to the prior year
        is primarily attributable to the 10.8% decline in capacity.
    
 
     Non-operating expenses (net of non-operating income) for 1993, 1992 and
1991 were $83.1 million, $56.9 million and $117.4 million, respectively.
Interest expense decreased to $54.2 million in 1993 from $55.8 million in 1992
and $61.9 million in 1991. In conformity with Statement of Position 90-7,
"Financial Reporting by Entities in Reorganization under the Bankruptcy Code,"
issued by the American Institute of Certified Public Accountants, the Company
has ceased accruing and paying interest on unsecured pre-petition long-term
debt. Had the Company continued to accrue interest on such debt, interest
expense for 1993, 1992 and 1991 would have been $73.0 million, $73.9 million and
$79.3 million, respectively. See Financial Statements and Supplementary
Data -- Notes 3a and 4 of Notes to Financial Statements.

     The Company incurred expenses of $25 million in 1993, $16.2 million in 1992
and $58.4 million in 1991 in connection with its efforts to reorganize under
Chapter 11. Such expenses for 1993 include net charges aggregating $18.2 million
in accruals for unsecured claims and settlements of administrative claims
primarily relating to leased aircraft which were returned to the lessors.
Reorganization related expenses are expected to significantly affect future
results and to continue until such time as the Company has obtained approval for
its plan of reorganization.
 
     Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS 109"). Since
there was no cumulative effect of this change in accounting, prior year
financial statements have not been restated.
 
   
LIQUIDITY AND CAPITAL RESOURCES
    
 
   
     At June 30, 1994, the Company had a working capital deficiency of $106.8
million, which declined from $124.4 million at December 31, 1993, primarily due
to an increase in cash and receivables resulting from improved operating
results. At June 30, 1994, cash and cash equivalents were $176.9 million,
compared to $99.6 million at December 31, 1993.
    
 
   
     On the Effective Date (estimated currently to be August 23, 1994), the
Company expects unrestricted and restricted cash balances to be approximately
$287 million and $21 million, respectively (compared to $25 million and $41
million, respectively, prior to the Chapter 11 filing). The estimates of
unrestricted cash include approximately $214.9 million relating to the issuance
of the Class A Common Stock, the Class B Common Stock and the Senior Notes. Such
projected cash balances are also net of estimated Plan confirmation payments of
approximately $141 million, including approximately $78 million of outstanding
D.I.P. financing.
    
 
   
     Upon implementation of the Plan, the Company's total estimated long-term
debt (including related current maturities and liabilities subject to
compromise) will be reduced from approximately $957 million to approximately
$634 million. On the Effective Date, stockholders' equity is expected to be
$587.5 million. Accordingly, on a pro forma basis, the Company's ratio of debt
to equity is anticipated to be 1.08 to 1.
    
 
     After the Effective Date, the Company will be substantially less leveraged
and will possess significantly greater liquidity than during the several years
prior to filing its Chapter 11 petition. It is anticipated that such projected
financial condition in conjunction with its current low cost structure will
enable the Company to better withstand future negative events, such as an
economic downturn, escalating fuel prices and intense fare competition, as well
as gain access to traditional market sources for its future financing
requirements. Substantial obligations relating to long-term aircraft and airport
terminal facilities leases will continue to exist.
 
     During 1993, the Company incurred capital expenditures of $54.3 million,
primarily relating to aircraft modifications and heavy airframe and engine
overhauls. The Company anticipates capital expenditures for 1994 to aggregate
$82 million primarily for rotable spare parts, aircraft modifications and major
overhauls. The Company expects to fund these capital expenditures with cash
provided by operations.
 
   
     At June 30, 1994, the Company had on order a total of 49 aircraft of the
types the Company currently operates, of which 29 are firm orders and 20 are
option orders. The current estimated aggregate cost for the acquisition of the
49 aircraft is approximately $2.7 billion (which amount may change as a result
of current negotiations and does not reflect any deliveries the Company may take
pursuant to put arrangements more fully discussed below). All of these aircraft
are to be purchased from Boeing or AVSA. For a more complete description of the
Company's rights and obligations with respect to the purchase of aircraft, see
"Business -- Aircraft."
    
 
   
     With respect to the agreements with Boeing, the B737-300 purchase contract
has been affirmed in the Company's bankruptcy proceedings. With timely notice to
the manufacturer, all or some of these deliveries may be converted to B737-400
aircraft. Existing purchase agreements for B757-200 and B747-400 aircraft have
neither been affirmed nor rejected. All Boeing purchase agreements require a
24-month reconfirmation notice for the delivery of each aircraft. As of June 30,
1994, ten B737-300 and nine B757-200 delivery positions have expired due to the
lack of reconfirmation by the Company, leaving 14 and 11 delivery positions
    
 
                                       31
<PAGE>   34
 
   
for B737-300s and B757-200s, respectively. The failure to reconfirm such
delivery positions exposes the Company to loss of pre-delivery deposits and
other claims which may be asserted in the bankruptcy proceeding. The Company
also has a pre-petition executory contract under which the Company holds
delivery positions for four B747-400 aircraft under firm order and four B747-400
aircraft under option order. This executory contract allows the Company, with
the giving of adequate notice, to substitute B737-400 aircraft for those
delivery positions. The Company is currently renegotiating all of its aircraft
purchase agreements with Boeing to finalize the details of this amendment.
    
 
     With respect to the purchase of aircraft from AVSA, a single executory
contract for the purchase of 24 A320 aircraft has neither been affirmed nor
rejected by the Company. As part of the investment by AmWest, the A320 purchase
agreement was amended to provide the Company with greater flexibility and
reduced pricing. Under the modified terms, delivery dates of the aircraft will
fall in the years 1998 through 2000 with an option to further defer deliveries.
In addition, if new A320 aircraft are delivered as a result of the renegotiated
put agreement (see discussion below), the Company will have the right to cancel
on a one-for-one basis up to a maximum of eight non-consecutive aircraft
deliveries, subject to certain conditions. Negotiations are currently continuing
between AVSA and the Company.
 
   
     During 1994, leases relating to four Boeing 737-200 aircraft, two Airbus
A320 aircraft and two Boeing 757 aircraft are scheduled to expire. The Company
has negotiated extensions of the leases for all but one of the Airbus A320
aircraft for terms ranging from one to three years. One Airbus A320 aircraft was
returned to the lessor and was replaced by a Boeing 757 aircraft which has been
leased for a term of three years. In June 1994, the Company renegotiated a put
agreement for ten A320 aircraft. The new agreement reduced the number of put
aircraft from ten to eight and rescheduled the deliveries to start not earlier
than June 30, 1995 and end on June 30, 1999. Under the new agreement, new or
used A320 aircraft, B737-300 or B757-200 aircraft may be put to the Company but
at a rate of no more than two in 1995 and with respect to each ensuing year
during the put period, of no more than three. In addition, no more than five
used aircraft may be put to the Company and for every new A320 aircraft put to
the Company, the Company has the right to reduce the AVSA A320 purchase contract
on a one-for-one basis. During each January of the put period, the Company will
negotiate the type and delivery dates of the put aircraft for that year. The
puts will require 150-day notice and will be leased at fair market rates, for
terms ranging from three to 18 years, depending on the type and condition of the
aircraft. As part of the renegotiated agreement, certain financial concessions
were granted to the put holder.
    
 
     Following the implementation of the Plan, the net operating loss
carryforwards (and other tax attributes) of the Company may be subject to the
limitations imposed by section 382 of the Internal Revenue Code ("Section 382").
 
     Under Section 382, if a corporation undergoes an ownership change, the
amount of its pre-change losses that may be utilized to offset future taxable
income generally will be subject to an annual limitation. The issuance of Class
B Common Stock pursuant to the Plan will constitute an ownership change of the
Company.
 
     Subject to certain exceptions, the Senior Note Indenture limits the
declaration or payment of dividends and certain other transactions (defined in
the Indenture as Restricted Payments). Such Restricted Payments are not
permitted if a Default or an Event of Default has occurred and is continuing,
and otherwise such payments are limited generally to 50% (or 75% if the Senior
Notes receive certain investment grade ratings) of Adjusted Consolidated Net
Income, as defined in the Indenture, plus proceeds of certain capital stock
issuances plus $25 million. At December 31, 1993, on a pro forma basis, the
Company would have had available approximately $37 million for dividends or
other Restricted Payments under such test (assuming the Effective Date was
January 1, 1993, the 50% test were applicable, no capital stock was issued for
any reason and there was no default under the Indenture). For a more detailed
description of these restrictions, see "Description of the Senior
Notes -- Certain Covenants."

                                    BUSINESS
 
   
     America West is a major United States air carrier providing passenger,
cargo and mail service, with its primary markets in the western and southwestern
regions of the United States. The Company operates its route system through two
principal hubs, Phoenix, Arizona and Las Vegas, Nevada, and a mini-hub in
Columbus, Ohio. As of July 31, 1994 America West operated a fleet of 85 jet
aircraft and provided service to 45 destinations. Through alliances with Mesa,
the Company provides connecting service to an additional 18 destinations. The
Company has also formed an alliance with Continental to serve additional
destinations.
    
 
   
     The Company filed a voluntary petition for protection under Chapter 11 of
the Bankruptcy Code on June 27, 1991. The Company's plan of reorganization (the
"Plan") was confirmed by the United States Bankruptcy Court for the District of
Arizona (the "Bankruptcy Court") on August 10, 1994. The Plan will become
effective on the date (the "Effective Date") on which certain conditions
specified in the Plan are satisfied or waived, which the Company expects to
occur on or about August   , 1994. In connection with its reorganization in
bankruptcy and related operational restructuring (the "Reorganization"), the
Company took significant steps to improve its operations, including (i) reducing
its fleet size from 123 aircraft in July 1991 to 85 in May 1994, facilitating a
better matching of capacity to demand through elimination of nonproductive
routes; (ii) reducing the aircraft types operated from five to three to reduce
operating costs; (iii) implementing certain enhancements to its revenue
management system to optimize the level of passenger revenues operated on each
flight; (iv) eliminating Company operated commuter service and introducing code-
sharing agreements to expand the scope of service and attract a broader
passenger base; and (v) implementing numerous cost reduction programs, including
a Company-wide pay reduction in August 1991 and the reduction of aircraft lease
rentals to fair market rates in the fall of 1992. As a result of these measures
as well as a gradually improving economic climate and a more stable environment
relative to fare competition within the airline industry, America West was one
of only two major airlines to report a profit in each quarter of 1993, realizing
net income for 1993 of $37.2 million and operating income of $121.1 million on
revenues of $1.33 billion.
    
 
BUSINESS STRATEGY
 
     The Company's business strategy is to continue to offer competitive fares
while providing an incrementally higher level of service relative to low cost
carriers generally. The principal features of the Company's business strategy
are as follows.
 
     Maintain Competitive Pricing While Providing Differentiated
Service.  America West currently operates with one of the lowest cost structures
among the major U.S. airlines, based on reported 1993 results. The Company's
operating cost per ASM for 1993 was 7.01 cents, which was approximately 25% less
than the average operating cost per ASM of the nine largest other domestic
airlines and was comparable to the cost structure of Southwest Airlines, which
operates in the Company's principal market areas. Management believes that the
Company can continue to offer fares that are competitive with those offered by
low cost carriers in the Company's markets, while providing a differentiated
level of service generally. Passenger services provided by America West include
assigned seating, participation in computerized reservation systems, interline
ticketing, first class cabins on certain flights, baggage transfer and various
other services. The Company believes that these features distinguish America
West from certain low cost carriers in the Company's markets, including
Southwest Airlines, and enable the Company to attract passengers without
competing solely on the basis of fares.
 
     Achieve Growth in Revenue Passenger Miles. Management believes the
Company's pricing and service strategies, together with a gradual improvement of
general economic activity, will enable the Company to achieve growth in revenue
passenger miles in its existing markets and to expand into certain other North
American markets. Management believes that growth in existing markets will be
achieved in part due to the location of the Company's principal hubs. Both
Phoenix and Las Vegas are experiencing population growth in excess of national
averages, and these hubs are well situated to benefit from an expanding market
for leisure travel.
 
                                       33
<PAGE>   36
 
     Expand Service through Alliances.  As a part of the Reorganization, the
Company entered into Alliance Agreements with Continental and Mesa. With
Continental, the Company agreed to implement certain code-sharing arrangements,
coordinate certain flight schedules to maximize connections between the two
airlines, share ticket counter space, link frequent flyer programs, and
coordinate ground handling operations. With Mesa, America West has entered into
two code-sharing agreements that establish Mesa as a feeder carrier for the
Company at its hubs in Phoenix and Columbus. The code-sharing agreements provide
for coordinated flight schedules, passenger handling and computer reservations
under the America West flight designator code, thereby allowing passengers to
purchase one air fare for their entire trip. Mesa connects 13 cities to the
Company's Phoenix hub, operates under the name "America West Express" and has
begun to incorporate the color scheme and commercial logo of America West on
certain aircraft utilized on these routes. Mesa serves five destinations from
the Company's Columbus mini-hub operations. Management believes the Alliance
Agreements will contribute significantly to the Company's growth in revenue
passenger miles and operating results.
 
   
     Maintain a Cost Effective Fleet.  In connection with its Reorganization,
the Company substantially reduced its aircraft fleet to the current level,
reduced the aircraft types from five to three and renegotiated lease rates for
certain aircraft to fair market rates. As of June 30, 1994, the Company's fleet
consisted of 56 Boeing 737s, 17 Airbus 320s and 12 Boeing 757s, with an average
age of approximately 8.6 years. The fleet enables the Company to achieve low
fuel costs compared to industry averages and to enjoy operational efficiencies
due to the limited number of aircraft types. Current plans provide for an
increase in the Company's fleet from 85 to 105 aircraft by 1997 through the
acquisition of additional aircraft of the types currently operated by the
Company.
    
 
OPERATIONS
 
     Hub Operations. The Company operates primarily through hub airports in
Phoenix and Las Vegas and, to a lesser extent, through its mini-hub in Columbus,
Ohio. The Company schedules banks of flights timed to arrive at the hub from one
direction at approximately the same time and to depart toward the opposite
direction a short time later. The hub system allows the Company to transport
passengers between a large number of destinations with substantially more
frequent service than if each route were served directly.
 
     The Company is the leading airline serving Phoenix Sky Harbor International
Airport with approximately 40% of all enplanements and an average of 149 daily
departures during 1993. In Las Vegas, the Company is the second largest carrier
with approximately 26% of all enplanements during 1993. In both markets the
Company's principal competitor is Southwest Airlines, which handled
approximately 30% and 29% of enplanements in Phoenix and Las Vegas,
respectively, in 1993. America West offers fares comparable to or below those of
its competitors on most routes. America West is able to use pricing as a part of
its strategy because of its ability to provide service generally comparable to
the full service airlines while maintaining a lower cost structure than these
competitors. In selected markets, America West has chosen not to match Southwest
Airlines' fares, but differentiates itself from Southwest Airlines in these and
other markets by providing assigned seating, interline ticketing, baggage
transfer and various other services typically offered by a full service carrier.
 
   
     The Company established a mini-hub at Columbus, Ohio in December 1991. As
of July 31, 1994, the Company provided non-stop jet service to 11 destinations
from Columbus. During 1993, the Company enplaned approximately 18% of the
Columbus traffic compared to approximately 21% and 12% for USAir and Delta,
respectively.
    
 
     The success of the Company's hub system depends on its ability to attract
passengers traveling to and from its hubs, as well as passengers traveling
through the hubs to the Company's other destinations. The Company believes that
several factors have contributed to the success of its operations in Phoenix and
Las Vegas. First, the rate of population growth in these two cities has exceeded
the national average in recent periods. Second, Phoenix and Las Vegas are
popular vacation destinations and, therefore, benefit from the fact that a
growing percentage of airline travelers are leisure or non-business travelers.
Third, the Company believes that certain costs of operating in Phoenix and Las
Vegas are less than in certain other geographic regions. Finally, these hub
operations allow the Company to serve a number of relatively high density routes
 
                                       34
<PAGE>   37
 
that involve short-and medium-haul service without competing directly in the
more intensely competitive long-haul markets against larger carriers.
 
     Hub operations involve certain inefficiencies that are primarily associated
with the need to maintain terminal resources adequate to deal with periods of
peak demand when numerous aircraft converge at the hub, even though this demand
occurs only a few times per day. As a result, certain carriers have emphasized
or announced intentions to initiate "point-to-point" flights not integrated with
hub operations that can potentially serve specific routes at lower cost than
comparable hub operations. Although the Company continually evaluates its
operating strategy in light of changing market conditions, the Company's current
strategy is to increase utilization of its existing hub facilities by increasing
frequency of service on existing routes served by its hub operations and
identifying selected markets into which the Company can expand utilizing its
existing hub operations. An important part of the Company's strategy involves
code-sharing arrangements with regional carriers that serve its hub airports and
alliances with major carriers that complement the Company's operations.
 
     Regional/Commuter Service.  A number of passengers served by the Company's
operations arrive at its hub airports via regional or commuter service airlines
that serve the surrounding areas. These airlines typically utilize turboprop
rather than jet aircraft and focus on flights less than 200 miles in length and
90 minutes in duration. In order to maximize the number of enplanements of
passengers from these commuter airlines, America West has entered into two
code-sharing agreements with Mesa designed to establish Mesa as a feeder carrier
for the Company at its hubs in Phoenix and Columbus. The code-sharing agreements
provide for coordinated flight schedules, passenger handling and computer
reservations under the America West flight designator code, thereby allowing
passengers to purchase one air fare for their entire trip. Mesa connects 13
cities to the Company's Phoenix hub, operates under the name "America West
Express" and has begun to incorporate the color scheme and commercial logo of
America West on aircraft utilized on these routes. Mesa services five
destinations from the Company's Columbus mini-hub operation. In connection with
the Reorganization, the Company and Mesa agreed to extend the terms of these
code-sharing agreements until 1999.
 
     Alliance Agreements.  In connection with its Reorganization, the Company
agreed to form an alliance with Continental pursuant to which the Company and
Continental agreed to implement certain code-sharing arrangements, coordinate
certain flight schedules, share ticket counter space, link frequent flyer
programs, and coordinate ground handling operations for mutual benefit. These
arrangements will be implemented in phases, commencing in the third quarter of
1994. The Company believes that it will realize substantial benefits from such
agreements, which are intended to increase the number of America West
enplanements of Continental passengers and vice versa. In addition, the Company
will be able to offer its existing customers connections to a greater number of
destinations served by Continental, which may permit the Company to further
increase its market share in its hub markets.
 
COMPETITION AND MARKETING
 
     The airline industry is highly competitive and susceptible to price
discounting, and America West must compete with carriers that are much larger
and have substantially greater resources. See "Investment
Considerations -- Adverse Industry Conditions and Competition." Generally, the
passenger carrier industry is segmented into markets based on the length of trip
and level of service, including long-haul domestic and international routes,
medium-haul (two to three hours) and short-haul (less than two hours) routes
serviced by jet aircraft, and commuter routes served by turboprop aircraft.
America West services primarily short-haul and medium-haul routes connected to
its hub operations, engages only to a limited extent in long-haul flights, which
are dominated by larger carriers, and does not engage in regional commuter
flights, which are primarily served by smaller non-jet carriers. America West
competes primarily with Southwest Airlines at its Phoenix and Las Vegas hub
operations and with USAir and Delta at its Columbus mini-hub.
 
     As is the case with other carriers, most tickets for travel on America West
are sold by travel agents through computer reservation systems that have been
developed and are controlled by other airlines. Travel agents generally receive
commissions based on the price of tickets sold. Accordingly, airlines compete
not only
 
                                       35
<PAGE>   38
 
with respect to the price of tickets sold but also with respect to the amount of
commissions paid. Airlines often pay additional commissions in connection with
special revenue programs. Federal regulations have been promulgated that are
intended to diminish preferential schedule displays and other practices with
respect to the reservation systems that place the Company and other similarly
situated users at a competitive disadvantage to the airlines controlling the
systems.
 
     The Company has implemented certain measures to increase leisure travel
utilizing America West flights. In 1987 the Company developed America West
Vacations, which is a tour packaging division that arranges vacation packages
that include hotel accommodations, air fare and ground transportation in certain
markets. During 1993, this division sold approximately 500,000 room nights and
over 315,000 round trip tickets and generated approximately $126 million in
gross revenues. In 1993, the Company became the preferred commercial air carrier
of the MGM Grand Hotel Casino and Theme Park ("MGM") in Las Vegas. Pursuant to
an agreement with MGM, America West will develop joint marketing programs that
target travel agents and consumers, which management believes will enhance
America West's presence in the Las Vegas market.
 
     The Company also has an exclusive arrangement with the Phoenix Suns
professional basketball team pursuant to which the arena in which the team plays
is named "America West Arena," and the Company's name and logo appear throughout
the facility, including on the basketball court. As a result of this
association, the Company receives media exposure at no additional expense during
national and local telecasts of Phoenix Suns basketball games, as well as during
other events at the arena.
 
FLIGHTFUND
 
     All major airlines have established frequent flyer programs to encourage
travel on that particular carrier. America West offers the FlightFund program
that allows members to earn mileage credits by flying America West and certain
other carriers and by using the services of other program participants such as
bank credit cards, hotels and car rental firms. In addition, the Company
periodically offers special short-term promotions that allow members to earn
additional free travel awards or mileage credits. When a FlightFund member
accumulates mileage credits of 20,000 miles, the Company issues mileage award
certificates that can be redeemed for various travel awards, including first
class upgrades and tickets on America West or other airlines participating in
America West's frequent flyer program. Travel is valid up to one year from the
date of ticketing. Most travel awards are subject to blackout dates and capacity
controlled seating. Mileage award certificates automatically expire after two
years if issued prior to April 1, 1993 and after three years for certificates
issued after that date.
 
     FlightFund awards may also be redeemed for flights to certain international
destinations and Hawaii. America West is required to purchase space on other
airlines to accommodate such award redemption. In addition, America West has
entered into barter agreements with certain hotels and rental car agencies that
permit the Company to award discounts at such hotels and rental agencies to
FlightFund members in exchange for providing air travel to such hotels and
travel agencies.
 
     The Company accounts for the FlightFund program under the incremental cost
method whereby travel awards are valued at the incremental cost of carrying one
additional passenger. Costs including passenger food, beverages, supplies, fuel,
liability insurance, purchased space on other airlines and denied boarding
compensation are accrued as frequent flyer program participants accumulate
mileage to their accounts. Such unit costs are based upon expenses expected to
be incurred on a per passenger basis. No profit or overhead margin is included
in the accrual for these incremental costs.
 
     FlightFund's current membership is approximately 1.6 million participants.
At December 31, 1993, 1992 and 1991, the Company estimated that approximately
238,000, 238,000 and 235,000 travel awards were expected to be redeemed.
Correspondingly, the Company had an accrued liability of $7.4 million, $7.3
million and $6.2 million for 1993, 1992 and 1991, respectively. The accrual is
based upon the Company's estimates of mileage earned that will eventually be
redeemed for a travel award.

<PAGE>   39
 
     The number of FlightFund travel awards redeemed for round-trip travel for
the years ended December 31, 1993, 1992 and 1991, was approximately 99,000,
106,000 and 160,000, respectively, representing 2.8%, 3.0% and 3.0% of total
revenue passenger miles for each respective period. The Company does not believe
that the usage of free travel awards results in any significant displacement of
revenue passengers due to the Company's ability to manage frequent flyer travel
by use of blackout dates and limited seat availability.
 
AIRCRAFT
 
   
     In connection with its restructuring, the Company reduced the size of its
fleet from 123 in 1991 to 85 in 1993. The Company also reduced the different
types of aircraft in the fleet from five to three. At June 30, 1994, the Company
operated a fleet of 56 Boeing 737s, 17 Airbus A320s and 12 Boeing 757s.
    
 
   
     The table below sets forth certain information regarding the Company's
aircraft fleet at June 30, 1994:

     Each of the aircraft that is designated as owned serves as collateral for a
loan pursuant to which the aircraft was acquired by the Company or serves as
collateral for a non-purchase money loan.
 
     From 1994 through 1997, leases are scheduled to terminate on six aircraft
(four Boeing 737-200s and two Boeing 757-200s). In addition, leases for two
Airbus A320-200s were scheduled to terminate during 1994; however, the Company
extended one such lease for an additional twelve months. The other Airbus A320
aircraft was returned to the lessor in May 1994 and was replaced by a Boeing 757
aircraft which has been leased for a term of three years. In addition, certain
of the aircraft lessors have the right to call their respective aircraft upon
(in most cases) 180 days' prior notice to the Company. The Company, in turn
(with some exceptions), may retain such aircraft via a right of first refusal by
agreeing to the bona fide terms offered by a third party interested in leasing
or purchasing the aircraft. The Company does not believe that such call rights,
which were granted in exchange for concessions on payment terms relating to such
aircraft, will materially affect the Company's operations.
 
     At June 30, 1994, the Company had on order a total of 49 aircraft of the
types the Company currently operates, of which 29 are firm orders and 20 are
optional orders. The table below details such deliveries.

     At June 30, 1994 the estimated aggregate cost for delivery positions under
the existing contracts for the acquisition of B737s, B757s and A320 aircraft
from manufacturers listed in the above table is approximately $2.7 billion. The
table does not include any deliveries under put arrangements more fully
discussed below nor does it include orders for B747-400 aircraft.
    
 
   
     With respect to various contracts with Boeing presented in the table above,
a purchase agreement to acquire B737-300 aircraft has been affirmed in the
Company's bankruptcy proceedings. With timely notice to the manufacturer, all or
some of these deliveries may be converted to B737-400 aircraft. Existing
purchase agreements for B757-200 and B747-400 aircraft have neither been
affirmed nor rejected. Boeing purchase agreements carry a 24-month
reconfirmation notice for the delivery of each aircraft. As of June 30, 1994,
ten B737-300 and nine B757-200 delivery positions have expired due to the lack
of reconfirmation by the Company, leaving 14 and 11 delivery positions as
reflected in the table above. The failure to reconfirm such delivery positions
exposes the Company to loss of pre-delivery deposits and other claims which may
be asserted in the bankruptcy proceeding. The Company also has a pre-petition
executory contract under which the Company holds delivery positions for four
B747-400 aircraft under firm order and four B747-400 aircraft under option
order. This executory contract allows the Company, with the giving of adequate
notice, to substitute B737-400 aircraft for those delivery positions. The
Company is currently renegotiating all of its aircraft purchase agreements with
Boeing.
    
 
   
     With respect to the purchase of aircraft from AVSA presented in the table
above, a single executory contract for the purchase of 24 A320 aircraft has
neither been affirmed nor rejected by the Company. As part of the investment by
AmWest, the A320 purchase agreement was amended to provide the Company with
greater flexibility and reduced pricing. Under the modified terms, delivery
dates of the aircraft will fall in the years 1998 through 2000 with an option to
further defer deliveries. In addition, if new A320 aircraft are delivered as a
result of the renegotiated put agreement (see discussion below), the Company
will have the right to cancel on a one-for-one basis up to a maximum of eight
non-consecutive aircraft deliveries subject to certain conditions. Negotiations
are currently continuing between AVSA and the Company to finalize the details of
this amendment.
    
 
   
     In June 1994, the Company renegotiated a put agreement for ten A320
aircraft. The new put agreement reduced the number of aircraft from ten to eight
and rescheduled the deliveries to start not earlier than June 30, 1995 and end
on June 30, 1999. Under the new agreement, new or used A320 aircraft, B737-300
or B757-200 aircraft may be put to the Company but at a rate of no more than two
in 1995 and with respect to each ensuing year during the put period, of no more
than three. In addition, no more than five used aircraft may be put to the
Company and for every new A320 aircraft put to the Company, the Company has the
right to reduce the AVSA A320 purchase contract on a one-for-one basis. During
each January of the put period, the Company will negotiate the type and delivery
dates of the put aircraft for that year. The puts will require 150-day notice
and will be leased at fair market rates, for terms ranging from three to 18
years, depending on the type and condition of the aircraft. As part of the
renegotiated agreement, certain cash payments will be made and certain
securities will be issued to the put holder pursuant to the Plan.
    
 
   
     In connection with the Company's $78 million D.I.P. financing agreement,
the Company in December 1991, terminated its agreement with a D.I.P. lender to
lease 24 aircraft and replaced it with a put agreement to lease up to ten of the
aircraft. In September 1992, the put agreement was amended and the number of put
aircraft was reduced from ten to four with the aircraft scheduled for delivery
in 1994. In June 1994, the Company reached a settlement for the cancellation of
the right to "put" four aircraft to the Company for $4.5 million of which $2.5
million was paid in June 1994 and $2.0 million will be paid on the Effective
Date.
    
 
FACILITIES
 
     America West's principal facilities are associated with its hub operations
in Phoenix, Las Vegas and Columbus. The Company operates from Terminal 4 of
Phoenix Sky Harbor International Airport pursuant to a lease agreement that
included 28 gates and approximately 258,200 square feet at December 31, 1993.
The Company also leases approximately 25,000 square feet of additional space at
the airport for administrative offices and pilot training. Since 1988, the
Company has owned a 660,000 square foot maintenance and
 
                                       38
<PAGE>   41
 
technical support facility that includes four hangar bays, hangar shops, two
flight simulator bays, and warehouse and commissary facilities.
 
     In Las Vegas, the Company leases approximately 80,000 square feet of space
at McCarran International Airport, which includes seven gates and adjoining
holding room areas. At the Company's Columbus, Ohio mini-hub, the Company leases
30,000 square feet and two gates and has the ability to sublease additional
gates from other airlines as the need arises.
 
     Space for ticket counters, gates and back offices has also been obtained at
each of the other airports served by the Company, either by lease from the
airport operator or by sublease from another airline. Some of the Company's
airport sublease agreements include requirements that the Company purchase
various ground services at the airport from the lessor airline at rates in
excess of what it would cost the Company to provide those services itself.
 
     The Company owns the 68,000 square foot America West Corporate Center at
222 South Mill Avenue in Tempe, Arizona. The Company currently leases
approximately 500,000 square feet of general office and other space in Phoenix
and Tempe, Arizona.
 
EMPLOYEES
 
     Management believes that the Company's dedicated labor force has
contributed significantly to its successful reorganization. At December 31,
1993, the Company employed 8,102 full-time and 3,117 part-time employees, the
equivalent of 10,544 full-time employees. During 1993, the Company had 1,630,400
available seat miles per full-time equivalent employee and 1,064,200 revenue
passenger miles per full-time equivalent employee, based on the number of
full-time equivalent employees at year end. The Company's payroll and related
costs, which amounted to 1.78 cents per available seat mile for the year ended
December 31, 1993, is below the industry average.
 
   
     On October 26, 1993, the Air Line Pilots Association ("ALPA") was certified
by the National Mediation Board as the bargaining representative of the
Company's flight deck crew members. Formal negotiations commenced in April 1994
and are continuing. Both sides have exchanged preliminary proposals. In February
1989, the Association of Flight Attendants ("AFA") lost an election to represent
the Company's customer service representatives ("CSRs"). In June, 1994, the
National Mediation Board accepted AFA's new petition to represent the Company's
CSRs and ballots are scheduled to be mailed to all eligible flight attendants in
August 1994. The ballot count will be held September 15, 1994. In April 1994,
the Transportation Workers Union ("TWU") filed a petition to represent the
Company's fleet service personnel. The Company anticipates that elections with
respect to the proposals will be held during 1994.
    
 
   
     The International Brotherhood of Teamsters (the "Teamsters") filed an
application to represent the Company's mechanics and related personnel on August
1, 1994. As of August 12, 1994 the National Mediation Board had not determined
whether it will order an election.
    
 
   
     The Company cannot predict whether either the AFA, TWU or the Teamsters
will be certified to represent any of the Company's employees or the effect, if
any, that a future collective bargaining agreement with any of the ALPA, AFA or
TWU will have on the Company's operations or financial performance.
    
 
     The Company has arranged a program of insurance of the types and in the
amounts it believes customary in the airline industry, including coverage for
public liability, passenger liability, property damage, aircraft loss or damage,
cargo liability and workers' compensation. The Company believes such insurance
is adequate as to both risks covered and coverage amounts.
 
GOVERNMENT REGULATIONS
 
     Noise Abatement.  The Airport Noise and Capacity Act of 1990 provides, with
certain exceptions, that after December 31, 1999, no person may operate certain
large civilian turbo-jet aircraft in the United States that do not comply with
Stage 3 noise levels, which is the FAA designation for the quietest commercial
jets. These regulations will require carriers to gradually phase out their
noisier jets (such as the Boeing 737-200),
 
                                       39
<PAGE>   42
 
either replacing them with quieter Stage 3 jets or equipping them with hush kits
to comply with noise abatement regulations, over a five-year period commencing
December 31, 1994. As of December 31, 1993, 73 percent of America West's fleet
was in compliance with the FAA noise abatement regulations, and the Company
expects that it will meet the thresholds imposed by such regulations through
scheduled retirement of its older aircraft.
 
     Numerous airports, including those serving Boston, Denver, Los Angeles,
Minneapolis-St. Paul, New York City, San Diego, San Francisco, San Jose, Orange
County, Washington, D.C., Burbank and Long Beach have imposed restrictions such
as curfews, limits on aircraft noise levels, mandatory flight paths, runway
restrictions and limits on number of average daily departures, which limit the
ability of air carriers to provide service to or increase service at such
airports. The Port Authority of New York and New Jersey is considering a
phaseout of Stage 2 aircraft on a more accelerated basis than that of the FAA
requirement. The Company's Boeing 757-200s, 737-300s and Airbus A320s all comply
with current FAA Stage 3 noise regulations, as well as the more stringent noise
abatement requirements of the airports listed above.
 
     PFC Charges.  During 1990, Congress enacted legislation to permit airport
authorities, with prior approval from the DOT, to impose passenger facility
charges ("PFCs") as a means of funding local airport projects. These charges,
which are intended to be collected by the airlines from their passengers, are
limited to $3.00 per enplanement, and to no more than $12.00 per round trip. As
a result of competitive pressure, the Company and other airlines have been
limited in their abilities to pass on the cost of the PFCs to passengers through
fare increases.
 
     Environmental Matters.  The Company is subject to regulation under major
environmental laws administered by state and federal agencies, including the
Clean Air Act, Clean Water Act and Comprehensive Environmental Response
Compensation and Liability Act of 1980. In some locations there are also county
and sanitary sewer district agencies which regulate the Company. The Company
believes that it is in substantial compliance with applicable environmental
regulations.
 
     Aging Aircraft Maintenance.  The FAA issued several Airworthiness
Directives ("AD") in 1990 mandating changes to the older aircraft maintenance
programs. These ADs were issued to ensure that the oldest portion of the
nation's fleet remains airworthy. The FAA is requiring that these aircraft
undergo extensive structural modifications. These modifications are required
upon the accumulation of 20 years time in service, prior to the accumulation of
a designated number of flight cycles or prior to 1994 deadlines established by
the various ADs, whichever occurs later. Only one of the Company's 85 aircraft
is currently affected by these aging aircraft ADs. The Company constantly
monitors its fleet of aircraft to ensure safety levels which meet or exceed
those mandated by the FAA or the DOT.
 
     Safety.  America West is subject to the jurisdiction of the FAA with
respect to aircraft maintenance and operations, including equipment, dispatch,
communications, training, flight personnel and other matters affecting air
safety. The FAA has the authority to issue new or additional regulations. To
ensure compliance with its regulations, the FAA requires the Company to obtain
operating, airworthiness and other certificates which are subject to suspension
or revocation for cause. In addition, a combination of FAA and Occupational
Safety and Health Administration regulations on both federal and state levels
apply to all of America West's ground-based operations.
 
     Slot Restrictions.  At New York City's JFK and LaGuardia Airports,
Chicago's O'Hare International Airport and Washington's National Airport, which
have been designated "High Density Airports" by the FAA, there are restrictions
on the number of aircraft that may land and take-off during peak hours. In the
future, these take-off and landing time slot restrictions and other restrictions
on the use of various airports and their facilities may result in further
curtailment of services by, and increased operating costs for, individual
airlines, including America West, particularly in light of the increase in the
number of airlines operating at such airports. In general, the FAA rules
relating to allocated slots at the High Density Airports contain provisions
requiring the relinquishment of slots for nonuse and permits carriers, under
certain circumstances, to sell, lease or trade their slots to other carriers.
 
                                       40
<PAGE>   43
 
     On January 1, 1993, the FAA implemented new slot use standards that require
that all slots must be used on 80% of the dates during each two-month reporting
period. Previously, slots were required to be used at a 65% use rate. Failure to
satisfy the 80% use rate will result in loss of the slot. The slot would revert
to the FAA and be reassigned through a lottery arrangement.
 
     The Company currently utilizes two slots at New York City's JFK airport,
four slots at New York City's LaGuardia airport, four slots at Chicago's O'Hare
airport and six slots at Washington's National airport. Four of the slots at
Washington's National airport are temporary and the Company's right to utilize
such slots expires in September 1994; however, the Company currently expects
that its right to utilize such slots will be renewed. The average utilization
rates by the Company of all the foregoing slots range from 86% to 100%.
 
     CRAF Program.  In time of war or during a national emergency, United States
air carriers may be required to provide airlift services to the Military Airlift
Command under the Civil Reserve Air Fleet Program (the "CRAF Program"). During
the Middle East conflict in 1990-91, two of America West's aircraft participated
in the CRAF Program.
 
LEGAL PROCEEDINGS
 
   
     On June 27, 1991, the Company filed a voluntary petition in the United
States Bankruptcy Court for the District of Arizona to reorganize under Chapter
11 of the United States Bankruptcy Code. The Company's plan of reorganization
was confirmed on August 10, 1994, and will become effective on the Effective
Date, which the Company anticipates will be on or about August   , 1994. The
Bankruptcy Court retains jurisdiction over the Company for limited purposes.
    
 
   
     In August 1991, the Securities and Exchange Commission informally requested
that the Company provide the Commission with certain information and
documentation underlying disclosures made by the Company in annual and quarterly
reports filed with the Commission by the Company in 1991. The Company has
cooperated with the Commission's informal inquiry. On March 29, 1994, the
Company's Board of Directors approved the submission of an offer of settlement
for the purpose of resolving the inquiry through the entry of a consent decree
pursuant to which the Company would, while neither admitting nor denying any
violation of the securities laws, agree to comply with its future reporting
obligations under Section 13 of the Exchange Act. The Company was advised on May
6, 1994 that the Commission agreed to accept the Company's offer of settlement.
In order to implement the settlement, on May 12, 1994 the Commission issued an
"Order Instituting Proceedings Pursuant to Section 21C of the Exchange Act and
Opinion and Order of the Commission" (the "Order") finding the Company's Form
10-K for the year ending December 31, 1990, violated Section 13(a) of the
Exchange Act and Rule 13a-1 thereunder, and that the Company's Form 10-Q for the
first quarter of 1991 violated Section 13(a) of the Exchange Act and Rule 13a-13
thereunder, and ordering that the Company cease and desist from violating
Section 13(a) of the Exchange Act and Rules 13a-1 and 13a-13 promulgated under
the Exchange Act. The Order provides that the Company neither admits nor denies
any violation of the securities laws.

OTHER ARRANGEMENTS
 
     Mr. Franke, Chairman of the Board of Directors, is also the president of
the financial services firm, Franke & Co. In order to assist Mr. Franke with
certain costs associated with his service as Chairman and Chief Executive
Officer, the Company pays Franke & Co. an office overhead allowance of $4,167
per month in exchange for which Franke & Co. provides Mr. Franke's secretarial
and administrative support.
 
   
     Effective January 1, 1994, Mr. A. Maurice Myers left his position as
president and chief executive officer of Aloha Airlines, Inc. to join the
Company as President and Chief Operating Officer. The employment agreement
between the Company and Mr. Myers provides an initial two-year term at a base
salary of $375,000 per year. Mr. Myers also received a $100,000 transition
allowance. The Company loaned Mr. Myers approximately $320,000 to exercise
options to acquire stock of Aloha Airlines, Inc. The loan is secured by the
stock purchased by Mr. Myers but is otherwise nonrecourse to Mr. Myers. The loan
bears interest at a rate based on the rate of imputed interest under the
Internal Revenue Code. The loan matures within a specified period following
expiration of the employment agreement or other termination of employment or, if
earlier, on the date that is 180 days after the first date on which the pledged
stock becomes eligible for sale by Mr. Myers on a national securities exchange
or automated quotation system. In addition, the Company has agreed to assist Mr.
Myers in purchasing a residence in Phoenix, Arizona with a nonrecourse loan of
up to $200,000 secured by such residence. In connection with the confirmation of
the Plan, the Company has submitted for Bankruptcy Court approval a payment to
Mr. Myers of a reorganization success bonus in the amount of $400,000. The
Company has also agreed to provide to Mr. Myers certain retirement benefits,
reduced for vested accrued benefits payable under plans maintained by his former
employer. If Mr. Myers' employment with the Company is terminated or his
responsibilities are materially altered following a change in control, he is
entitled to receive a severance payment equal to 200% of his base salary and,
for a period of 12 months, medical and life insurance coverages as provided
immediately prior to such termination. Mr. Myers is entitled to participate in
any incentive plans or other fringe benefits provided by the Company to other
key employees.
    
 
     During 1993, the Company paid approximately $47,000 for consulting services
to Juan O'Callaghan, a former director of the Company.
 
   
     The Company and Mr. Franke entered into a Key Employee Protection Agreement
on June 27, 1994 pursuant to which the Company agreed to pay to Mr. Franke a
Severance Payment (as defined in the agreement) if a Change of Control (as
defined in the agreement) occurs in connection with a plan of reorganization and
if for any reason (including voluntary resignation or involuntary removal, but
excluding death) Mr. Franke ceases to serve as Chairman of the Company at any
time within 180 days after the date of confirmation of such a plan of
reorganization. A Change of Control (as defined in the agreement) would occur,
generally, (i) if individuals who constitute the Board of Directors of the
Company immediately prior to confirmation of a plan of reorganization cease to
constitute a majority of the Board (except that any individual who becomes a
director after the date of the agreement whose election or nomination was
approved by a majority of directors then comprising the incumbent Board is to be
considered as though he were a member of the incumbent Board), or (ii) if an
individual, entity or group (within the meaning of the Securities Exchange Act
of 1934, as amended) acquires beneficial ownership of 51% or more of the
combined voting power of the then outstanding voting securities of the Company
entitled to vote generally in the election of directors. Under the agreement,
the Severance Payment would be a lump sum amount equal to 200% of the sum of Mr.
Franke's annual base salary in effect immediately prior to the date of
termination and the administrative expense allowance then in effect. The Key
Employee Protection Agreement also provides for certain other benefits,
including medical and life insurance, accrued vacation pay for a 12 month period
and certain travel privileges consistent with the Company's policy for retired
executives.
    
 
   
     In connection with the confirmation of the Plan, the Company filed certain
motions with the Bankruptcy Court to secure approval to pay the reorganization
success bonuses of (i) $9.2 million to be paid to non-officer employees; (ii)
$1.2 million to be paid to officers and other members of management; and (iii)
125,000 shares of stock in the reorganized Company to be issued to William A.
Franke. A hearing on these motions has been scheduled for August 24, 1994.

                       COMPENSATION COMMITTEE INTERLOCKS
                           AND INSIDER PARTICIPATION
 
   
     The Compensation Committee of the Company's Board of Directors reviews all
aspects of compensation of executive officers of the Company and makes
recommendations on such matters to the full Board of Directors. The Compensation
Committee also reviews and approves all compensation and employee benefit plans,
the Company's organizational structure and plans for the development of
successors to corporate officers and other key members of management. During
1993, Frederick W. Bradley, Jr., Richard C. Kraemer, James T. McMillan, John R.
Norton, III and John F. Tierney served on the Compensation Committee.
    
 
   
     Both Mr. Tierney and Declan Treacy were elected to the Board of Directors
pursuant to a certain management letter agreement, as amended and restated,
between the Company and its debtor-in-possession lenders, including GPA. See
"Management -- Directors and Executive Officers". Both Mr. Tierney and Mr.
Treacy are executives of GPA. The management letter agreement will terminate as
of the Effective Date and GPA's representation on the Company's Board will be
determined pursuant to the Stockholders' Agreement and a voting agreement to be
entered between GPA and AmWest which collectively provide that GPA shall be
allocated one seat on the Company's Board of Directors for so long as it owns at
least 2% of the voting equity securities of the Company determined on a
fully-diluted basis.
    
 
   
     GPA has been and will continue to be a major supplier of leased aircraft
and engines to the Company and has provided financing for the Company prior to
and during the bankruptcy proceedings. In September 1990, GPA and the Company
entered into an agreement (the "Aircraft Finance Agreement") pursuant to which
(i) GPA provided a cash advance to the Company of $60.2 million and (ii) the
Company agreed to sublease 16 A320-200's and three spare engines and committed
to lease 10 additional A320-200's. Under the Aircraft Finance Agreement, the
monthly rental rates for each of the initial 12 aircraft is approximately
$307,000 (including adjustments in connection with certain security arrangements
and repayment of certain advances) and the monthly rental rates for each of the
remaining four aircraft averages approximately $345,000. The Company's
obligations under the Aircraft Finance Agreement are secured by a $17.6 million
letter of credit.
    
 
   
     In June of 1991, GPA and the Company restructured the Aircraft Finance
Agreement by eliminating the Company's obligations with respect to the 10
additional A320-200 aircraft, increasing the payments on the initial 12 aircraft
to repay advances on the cancelled aircraft as reflected above, and entering
into a put agreement (the "1991 Put Agreement"). Under the 1991 Put Agreement,
GPA is entitled to put 10 A320 aircraft to the Company over a three-year period.
Specified lease terms range from 18 to 23 years for a leveraged lease and seven
to 18 years for a single investor lease. Applicable rental rates are based on a
rental factor (.925% per month for a leveraged lease and 1.14% per month for a
single investor lease) multiplied by the cost of the aircraft to GPA. Rental
factors are subject to a 10-year reset provision based on changes in Treasury
rates in the case of leveraged leases and six-month adjustments based on LIBOR
rates in the case of single investor leases.
    
 
   
     In September 1991, after commencement of the Company's bankruptcy
proceedings, affiliates of GPA provided the Company $35 million of D.I.P.
financing. An additional $35 million was provided in September 1992. As of June
30, 1994, the aggregate outstanding principal balance of D.I.P. financing
provided by GPA was $54.4 million. The D.I.P. financing provided by GPA bears
interest at 350 basis points over the 90-day LIBOR rate and, along with the
other debtor-in-possession financing, is secured by substantially all of the
assets of the Company. Pursuant to the Plan and in accordance with a settlement
agreement to be entered into as of the Effective Date (the "Settlement
Agreement"), the Company will repay to GPA the outstanding balance under the
D.I.P. loan. In addition, GPA will receive 900,000 shares of Class B Common
Stock, 1,384,615 Warrants and a cash payment of $30.525 million, and the 1991
Put Agreement will be replaced with a new put agreement. The new put agreement
will reduce the number of aircraft from 10 to eight and reschedule the
deliveries to start not earlier than June 30, 1995 and to end on June 30, 1999,
unless otherwise agreed to by the Company. Under the new agreement, A320
aircraft with A-5 engines, B737-300 aircraft or B757-200 aircraft may be put to
the Company, but at a rate of no more than two in 1995 and no more than three in
each ensuing year during the put period. No more than five used aircraft may be
put to the Company,
    
 
                                       50
<PAGE>   53
 
   
and for every A320 aircraft (which may only be new aircraft) put to the Company,
the Company has the right to reduce the AVSA A320 purchase contract delivery on
a one-for-one basis. During each January of the put period, the Company and GPA
will negotiate the type and delivery dates of the put aircraft for that year.
The puts will require 150-day notice and will be leased at fair market rates,
for terms ranging from three to 18 years, depending on the type and condition of
the aircraft.
    
 
   
     Lease payments from America West to GPA under the Aircraft Finance
Agreement and the 1991 Put Agreement totaled $20,784,669 in 1991, $63,812,425 in
1992 and $63,073,184 in 1993. As of December 31, 1993, the Company was obligated
to pay approximately $1.136 billion over the terms of the 16 aircraft leases
under the Aircraft Finance Agreement. Payments by the Company to GPA under the
D.I.P. financing totalled $1,026,000 in 1991, $3,328,608 in 1992 and $16,298,189
in 1993.
    
 
                              CERTAIN TRANSACTIONS
 
     In September 1993, in connection with an extension of its
debtor-in-possession financing, the Company repaid $8.3 million of indebtedness
to Ansett Worldwide Aviation U.S.A., an affiliate of Transpacific Enterprises,
Inc., which was then a substantial stockholder of the Company. As of December
31, 1993, the Company leased or subleased 11 Boeing 737 aircraft from affiliates
of Transpacific Enterprises, Inc. and was obligated to pay $232 million over the
remaining terms of the leases.
 
     As part of the Reorganization, the Company entered into Alliance Agreements
with Continental and Mesa. See "Business -- Business Strategy" and
"Business -- Operations."
 
     Each of the transactions described above were the result of significant
negotiation among the parties thereto and were concluded on what the Company
believes to be terms no less favorable than would have been obtained had the
transactions been entered into with non-affiliated third parties. For a
description of certain transactions or arrangements between the Company and its
officers or directors, see "Management -- Other Arrangements."

STOCKHOLDERS' AGREEMENTS
 
     As of the Effective Date, the Company, AmWest, GPA and certain designated
stockholder representatives will enter into an agreement (the "Stockholders'
Agreement") with respect to certain matters involving the Company. The material
provisions of the Stockholders' Agreement are summarized below. The following
description, however, is only a summary and is qualified in its entirety by
reference to the Stockholders' Agreement, a copy of which has been filed as an
exhibit to the Registration Statement of which this Prospectus is a part.
 
     The Stockholders' Agreement provides that for a period lasting until the
first annual meeting after the third anniversary of the Effective Date (the
"Third Annual Meeting"), America West's Board of Directors will consist of 15
members including (i) nine members designated by AmWest; (ii) one member
designated by GPA for as long as GPA retains at least two percent of the voting
equity securities of the Company; and (iii) five independent directors (the
"Independent Directors") initially including (a) three designated by the
Creditors' Committee, (b) one member designated by the Equity Committee, and (c)
one director designated by the pre-Reorganization Board of Directors from among
the executive officers of the Company. Until the Third Annual Meeting, AmWest
and GPA will vote all shares of the Common Stock owned by them in favor of the
reelection of the initially designated Independent Directors for as long as such
Independent Directors continue to serve.
 
     In addition to the voting and other provisions of the Stockholders'
Agreement, AmWest and GPA have agreed that (i) AmWest will vote in favor of
GPA's nominee to the Company's Board of Directors, and (ii) GPA will vote in
favor of AmWest's nine nominees to the Company's Board of Directors for so long
as (a) AmWest owns at least 5% of the voting equity securities of the Company,
and (b) GPA owns at least 2% of the voting equity securities of the Company.
 
     The Stockholders' Agreement also provides that no director nominated by
AmWest will be an employee or officer of Continental. All directors who are
selected by or who are directors of Continental or Mesa and all directors who
are employees or officers of Mesa shall recuse themselves from voting on or
receiving information on any matters involving negotiations or direct
competition between Mesa and America West or Continental and America West,
whichever the applicable case may be.
 
     Until the Third Annual Meeting, approval by at least the three Independent
Directors or the affirmative vote of the holders of a majority of the voting
power of each class of Common Stock (excluding those shares owned by AmWest or
any of its Affiliates, as defined in the Stockholders' Agreement, but not,
however, excluding any shares owned, controlled or voted by Mesa or any of its
transferees that are not otherwise Affiliates of AmWest) is required to approve
(i) any merger or consolidation of the Company with or into AmWest or any of its
Affiliates; (ii) certain transactions involving issuances of voting securities
by the Company that result in AmWest or any of its Affiliates acquiring an
increased percentage ownership of such voting securities; and (iii) any
transaction or series of transactions having the same effect as (i) or (ii)
above.
 
     Under the terms of the Stockholders' Agreement, neither AmWest nor any
partner or Affiliate of AmWest or of any partner of AmWest may sell or otherwise
transfer any Common Stock (other than to an Affiliate of the transferor) if,
after giving effect thereto or to any related transaction, the total number of
shares of Class B Common Stock beneficially owned by the transferor is less than
twice the number of shares of Class A Common Stock beneficially owned by the
transferor, except in certain circumstances.
 
     In addition, the Stockholders' Agreement provides that for a period of
three years after the Effective Date, AmWest shall not sell, in a single
transaction or related series of transactions, shares of Common Stock
representing 51% or more of the combined voting power of shares of Common Stock
then outstanding other than (i) pursuant to or in connection with a tender or
exchange offer for all shares of Common Stock and for the benefit of all holders
of Class B Common Stock on a pro rata basis at the same price per share and on
the same economic terms, (ii) to any Affiliate of AmWest, (iii) to any Affiliate
of AmWest's partners, (iv) pursuant to a bankruptcy or insolvency proceeding,
(v) pursuant to judicial order, legal process, execution or attachment or (vi)
in a Public Offering as defined in the Stockholders' Agreement.

                            SELLING SECURITYHOLDERS
 
   
     The Selling Securityholders are the partners of AmWest, GPA and Fidelity.
AmWest is a limited partnership including Mesa and Continental. Pursuant to
partial assignments of the Investment Agreement by AmWest, Fidelity and Lehman
also purchased Securities from the Company through subscription agreements
between AmWest and those parties. Pursuant to the Reorganization Plan, AmWest
and such parties invested $214.9 million into the Company in exchange for the
Securities offered hereby. It is contemplated that prior to, on, or after the
Effective Date AmWest will distribute the Securities held by it to its partners,
and such Securities will be held directly by the partners of AmWest.
    
 
     The following table sets forth the name of each Selling Securityholder,
assuming the distribution of the Securities held by AmWest to its partners, and
the amount of the Securities (other than the Senior Notes) owned by each such
Selling Securityholder which are subject to being offered hereby. In addition,
Fidelity holds $100 million principal amount of the Senior Notes all of which
may be offered and sold pursuant to this Prospectus.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     At the Effective Date, assuming no exercise of outstanding warrants to
purchase Common Stock, America West will have 45,000,000 shares of Common Stock
outstanding, including 1,200,000 shares of Class A Common Stock and 43,800,000
shares of Class B Common Stock; the offer and sale of 15,975,000 of such shares
of Common Stock is registered under the Securities Act pursuant to the
Registration Statement of which this Prospectus forms a part. In addition, at
the Effective Date, America West will have 10,384,615 shares of Class B Common
Stock reserved for issuance upon the exercise of Warrants; the offer and sale of
4,153,846 of such shares is registered pursuant to the Registration Statement of
which this Prospectus forms a part.
    
 
     At the Effective Date, substantially all of the outstanding shares of
Common Stock and shares of Common Stock issuable upon exercise of the Warrants
(except to the extent such shares may have been acquired by an underwriter) will
be freely tradeable without restriction or further registration under the
Securities Act, either because such shares were issued or are issuable pursuant
to the exemption provided by Section 1145 of the Bankruptcy Code and such shares
are not "restricted securities" as defined in Rule 144 under the Securities Act
or because the offer and resale of such shares is registered pursuant to the
Registration Statement of which this Prospectus forms a part. To the extent
shares of Common Stock are owned or purchased by "affiliates" of the Company as
such term is defined in Rule 144 and are not registered
 
                                       55
<PAGE>   58
 
pursuant to the Registration Statement of which this Prospectus forms a part,
such restricted shares may generally be sold in compliance with Rule 144.
 
     In general under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated), including persons deemed to be affiliates, whose
restricted securities have been fully paid for and held for at least two years
from the later of the date of acquisition from America West or an affiliate
thereof, may sell such securities in brokers' transactions or directly to market
makers, provided the number of shares sold in any three-month period does not
exceed the greater of 1% of the then outstanding shares of the Common Stock or
the average weekly trading volume in the public market during the four calendar
weeks immediately preceding the filing of the seller's Form 144. Sales under
Rule 144 are also subject to certain notice requirements and availability of
current public information concerning America West. Pursuant to Rule 144(k),
after three years have elapsed from the later of the acquisition of the
restricted securities from America West or an affiliate thereof, such shares may
be sold without limitation by persons who have not been affiliates of America
West for at least three months.
 
     AmWest, Fidelity, Lehman and GPA have certain rights pursuant to agreements
with the Company to have the offering and sale of Securities held by them
registered with the Commission under the Securities Act. Under such agreements,
the Company may be required to effect such registration for a period of   years
from the Effective Date.
 
     Prior to this offering, there has been no market for the Common Stock of
America West. Future sales of substantial amounts of Common Stock in the public
market could adversely affect prevailing market prices.
 
                        DESCRIPTION OF THE SENIOR NOTES
 
   
     The Senior Notes will be issued under an Indenture dated as of
            , 1994 (the "Indenture") between the Company and American Bank
National Association, as trustee (the "Trustee"). The material provisions of the
Senior Notes and the Indenture are summarized below. The statements under this
caption relating to the Senior Notes and the Indenture are summaries only,
however, and do not purport to be complete. Such summaries make use of terms
defined in the Indenture and are qualified in their entirety by express
reference to the Indenture, which has been filed as an exhibit to the
Registration Statement of which this Prospectus is a part. All section
references under this heading are references to sections of the Indenture.
    
 
GENERAL
 
   
     Each Senior Note will mature on September 1, 2001, and will bear interest
at the rate per annum stated on the cover page hereof from the date of issuance,
payable semiannually in arrears on March 1 and September 1 of each year,
commencing March 1,1995, to the person in whose name the Senior Note is
registered at the close of business on the record date next preceding such
interest payment date. Interest will be computed on the basis of a 360-day year
of twelve 30-day months. The Company will pay the principal on the Senior Notes
to each Holder who surrenders such Senior Notes to a Paying Agent on or after
September 1, 2001 or, in the event of a redemption of the Senior Notes, on or
after the Redemption Date, as described below. The Company will pay principal
and interest in U.S. legal tender by Federal funds bank wire transfer or (in the
case of payment of interest) by check to the persons who are registered Holders
at the close of business on the Record Date next preceding the applicable
interest payment date. The aggregate principal amount of the Senior Notes that
may be issued will be limited to $100,000,000.
    
 
     The Senior Notes will be transferable and exchangeable at the office of the
Registrar and any co-registrar and will be issued in fully registered form,
without coupons, in denominations of $1,000 and any whole multiple thereof;
provided, however, that any Global Security representing all or a portion of the
Senior Notes may not be transferred except as a whole by the Depository in
certain circumstances unless and until it is exchanged in whole or in part for
Senior Notes in a non-global form. The Company may require payment of a sum
sufficient to cover any transfer tax or other similar governmental charge
payable in connection with certain transfers and exchanges.
 
                                       56
<PAGE>   59
 
RANKING
 
     The Senior Notes will be senior unsecured obligations of the Company and
will rank pari passu in right of payment with the Company's existing and future
senior unsecured obligations.
 
OPTIONAL REDEMPTION
 
   
     The Company, at its option on notice to the Holders, may redeem the Senior
Notes (i) prior to September 1, 1997 (A) at any time in whole but not in part,
at a Redemption Price equal to 105% of the aggregate principal amount of the
Senior Notes, plus accrued and unpaid interest thereon to the Redemption Date,
or (B) from time to time in part from the Net Offering Proceeds received by the
Company prior to           , 1997 from a Public Offering Sale at a Redemption
Price equal to 105% of the aggregate principal amount of the Senior Notes so
redeemed, plus accrued and unpaid interest thereon to the Redemption Date; and
(ii) on and after September 1, 1997 at any time in whole or from time to time in
part, at a Redemption Price equal to the applicable percentage of the aggregate
principal amount of the Senior Notes so to be redeemed, set forth below, plus
accrued and unpaid interest thereon to the Redemption Date if redeemed during
the 12 calendar months beginning on             of the years indicated below:
    
 
                             1997:          105.0%
                             1998:          103.3%
                             1999:          101.7%
                             2000:          100.0%
 
   
MANDATORY REDEMPTION
    
 
   
     If the Company shall consummate a Public Offering Sale at any time or from
time to time prior to           , 1997, it shall, promptly after each Public
Offering Sale so consummated at a time when, immediately prior to such
consummation, the Company shall have on hand cash and Cash Equivalents, not
subject to any restriction on disposition, of at least $100,000,000, then the
Company shall redeem Senior Notes at a redemption price equal to 104% of the
aggregate principal amount of the Senior Notes so redeemed, plus accrued and
unpaid interest to the redemption date. The aggregate redemption price and
accrued and unpaid interest of the Senior Notes to be redeemed shall equal the
lesser of (x) 50% of such Net Offering Proceeds or (y) the excess, if any, of
$20,000,000 over (ii) the amount of any Net Offering Proceeds of any prior
Public Offering Sale received prior to           , 1997, and applied to redeem
Senior Notes as described therein.
    
 
   
     The Senior Notes will not be entitled to the benefit of any sinking fund or
other mandatory redemption provisions.
    
 
CERTAIN COVENANTS
 
     Limitations on Restricted Payments.  Under the terms of the Indenture,
neither the Company nor any subsidiary shall: (i) declare or pay any dividends
on or make any distributions in respect of Capital Stock of the Company (other
than dividends or distributions payable solely in shares of Capital Stock (other
than redeemable stock) or in options, warrants or other rights to purchase
Capital Stock (other than Redeemable Stock)) to holders of Capital Stock of the
Company, (ii) purchase, redeem or otherwise acquire or retire for value (other
than through the issuance solely of Capital Stock (other than Redeemable Stock))
or warrants, rights or options to acquire Capital Stock other than Redeemable
Stock; (iii) redeem, repurchase, defease (including, but not limited to, in
substance or legal defeasance), or otherwise acquire or retire for value (other
than through the issuance solely of Capital Stock (other than Redeemable Stock)
or warrants, rights or options to acquire Capital Stock (other than Redeemable
Stock)) (collectively, a "prepayment"), directly or indirectly (including by way
of amendment of the terms of any Indebtedness in connection with any retirement
or acquisition of such Indebtedness) other than at scheduled maturity thereof or
by any scheduled repayment or scheduled sinking fund payment, any indebtedness
of the Company which is subordinated in right of payment to the Senior Notes or
which matures after the maturity date of the Senior Notes except out of the
proceeds of Refinancing Indebtedness); if, at the time of such transaction
described in clause (i), (ii) or (iii) (such transactions being hereinafter
collectively referred to as "Restricted Payments") and after giving
 
                                       57
<PAGE>   60
 
effect thereto, either the aggregate amount expended by the Company and its
Subsidiaries for all Restricted Payments (the amount of any Restricted Payment
if other than cash to be the fair market value of the property included in such
payment as determined in good faith by the Board of Directors as evidenced by a
Board Resolution) from and after the Closing Date shall exceed the sum of (A)
50% (or if the Senior Notes at the time of the proposed Restricted Payment are
rated Investment Grade by at least one rating agency of recognized standing
selected by the Company, 75%) of the aggregate Adjusted Consolidated Net Income
(or if such Adjusted Consolidated Net Income is a loss, minus 100% of such loss)
of the Company and its Subsidiaries for the period from the Closing Date and
through the day immediately prior to the day on which the Restricted Payment
occurs, calculated on a cumulative basis as if such period were a single
accounting period; (B) the aggregate net proceeds received by the Company after
the Closing Date (including the fair market value of non-cash proceeds as
determined in good faith by the Board of Directors as evidenced by a Board
Resolution) from any Person other than a Subsidiary, as a result of the issuance
of (or contribution to capital on) Capital Stock (other than any Redeemable
Stock) or warrants, rights or options to acquire Capital Stock (other than any
Redeemable Stock); (C) the aggregate net proceeds received by the Company after
the Closing Date from any Person other than a Subsidiary as a result of the
issuance of Capital Stock (other than Redeemable Stock) upon conversion or
exchange of Indebtedness or upon exercise of options, warrants or other rights
to acquire such Capital Stock and (D) $25,000,000. For purposes of any
calculation that is required to be made in respect of, or after the declaration
of a dividend by the Company, such dividend shall be deemed to be paid at the
date of declaration and shall be included in determining the aggregate amount of
Restricted Payments, and the subsequent payment of such dividend shall not be
treated as an additional payment.
 
     For the purposes of the preceding covenant, the net proceeds from the
issuance of shares of Capital Stock of the Company upon conversion of debt
securities shall be deemed to be an amount equal to the net book value of such
debt securities (plus the additional amount required to be paid upon such
conversion, if any), less any cash payment on account of fractional shares; the
"net book value" of a security shall be the net amount received by the Company
on the issuance of such security, as adjusted on the books of the Company to the
date of conversion.
 
     Notwithstanding the foregoing, if no Default or Event of Default shall have
occurred or be continuing at the time the Indenture shall not prohibit (i) the
purchase, redemption or other acquisition or retirement for value of any shares
of the Company's Capital Stock or the prepayment of any indebtedness of the
Company which is subordinated in right of payment to the Senior Notes or which
matures after the maturity date of the Senior Notes by any exchange for, or out
of and to the extent the Company has received cash proceeds from the
substantially concurrent sale or issuance (other than to a Subsidiary) of,
shares of Capital Stock (other than any Redeemable Stock of the Company) or
warrants, rights or options to acquire Capital Stock (other than any Redeemable
Stock); or (ii) the purchase or redemption of shares of Capital Stock of the
Company (including options on any such shares or related stock appreciation
rights or similar securities) held by officers or employees of the Company or
its Subsidiaries (or their estates or beneficiaries under their estates) upon
death, disability, retirement, termination of employment or pursuant to the
terms of any Plan or any other agreement under which such shares of stock or
related rights were issued, provided that the aggregate amount of such purchases
or redemptions of such Capital Stock shall not exceed $3,000,000 in any one
fiscal year of the Company.
 
   
     Limitation on Transactions with Affiliates.  Neither the Company nor any
Subsidiary of the Company shall, directly or indirectly (i) sell, lease,
transfer or otherwise dispose of any of its properties or assets, or issue
securities to, (ii) purchase any property, assets or securities from, (iii) make
any Investment in, or (iv) enter into or suffer to exist any contract or
agreement with or for the benefit of, an Affiliate or Holder of 5% or more of
any class of Capital Stock (and any Affiliate of such Holder) of the Company (an
"Affiliate Transaction"), other than (x) certain permitted Affiliate
Transactions and (y) Affiliate Transactions (including lease transactions) which
are on fair and reasonable terms no less favorable to the Company or such
Subsidiary, as the case may be, as those as might reasonably have been
obtainable at such time from an unaffiliated party; provided that if an
Affiliate Transaction or series of related Affiliate Transactions involves or
has a value in excess of $10 million, the Company or such Subsidiary, as the
case may be, shall not enter into such Affiliate Transaction or series of
related Affiliate Transactions unless a majority of the disinterested members of
the
    
 
                                       58
<PAGE>   61
 
   
Board of Directors of the Company or such Subsidiary shall reasonably and in
good faith determine that such Affiliate Transaction is fair to the Company or
such Subsidiary, as the case may be, or is on terms no less favorable to the
Company or such Subsidiary, as the case may be, than those as might reasonably
have been obtainable at such time from an unaffiliated party.
    
 
   
     (b) The preceding paragraph shall not apply to (i) any agreement as in
effect as of the Closing Date, or any amendment thereto (including pursuant to
any amendment thereto) so long as any such amendment is not disadvantageous to
the Holders in any material respect or any transaction contemplated thereby
(including pursuant to any amendment thereto); (ii) any transaction between the
Company and any Wholly Owned Subsidiary or between Wholly Owned Subsidiaries,
provided such transactions are not otherwise prohibited by this Indenture; (iii)
reasonable and customary fees and compensation paid to, and indemnity provided
on behalf of, officers, directors, employees or consultants of the Company or
any Subsidiary, as determined by the Board of Directors of the Company or any
Subsidiary or the senior management thereof in good faith; (iv) any Restricted
Payments not prohibited in Section 4.13; (v) any payments or other transactions
pursuant to any tax sharing agreement between the Company and any other Person
with which the Company is required or permitted to file a consolidated tax
return or with which the Company is or could be part of a consolidated group for
tax purposes; and (vi) transactions with Continental, Mesa and their respective
Affiliates as contemplated by Alliance Agreements.
    
 
   
     Limitation on Asset Sales.  Subject to certain provisions of the Indenture,
in the event and to the extent that on any date the Company or any of its
Subsidiaries shall receive Net Cash Proceeds from one or more Asset Sales (other
than Asset Sales by the Company or any Subsidiary to the Company or another
Subsidiary) then the Company shall, or shall cause such Subsidiary to, within 12
months after such date apply an amount equal to such Net Cash Proceeds (A) and
to repay Indebtedness of the Company or Indebtedness of any Subsidiary, in each
case owing to a Person other than the Company or any of its Subsidiaries, and/or
(B) as an investment (or enter into a definitive agreement committing to so
invest within 12 months after the date of such agreement), in property or assets

EVENTS OF DEFAULT
 
   
     An Event of Default, with respect to the Senior Notes, means any one of the
following events shall have occurred and be continuing: (i) default by the
Company for 30 days in payment of any interest on the Senior Notes; (ii) default
by the Company in any payment of principal of or premium, if any, on the Senior
Notes when such payment becomes due and payable; (iii) default by the Company in
performance of any other covenant or agreement in the Indenture or under the
Senior Notes, which shall not have been remedied within 30 days after receipt of
written notice from the Trustee or from the holders of at least 25% in principal
amount of the Senior Notes then outstanding; (iv) upon an event of default
resulting in the acceleration of the maturity of any issue or issues of
Indebtedness of the Company and/or one or more Subsidiaries of any principal
amount of $10 million or more in the aggregate, and such default shall be
continuing for a period of 30 days without the Company or such Subsidiary, as
the case may be, discharging the Indebtedness or effecting a cure of such
default; (v) a judgment or order not covered by insurance for the payment of
money in excess of $10 million having been rendered against the Company or any
Subsidiary and such judgment or order shall continue unsatisfied and unstayed
for a period of 60 days; or (vi) certain events involving bankruptcy, insolvency
or reorganization of the Company or any Material Subsidiary; (vii) failure by
the Company to make at the final (but not any interim) fixed maturity of one or
more issues of Indebtedness a principal payment or principal payments
aggregating 10 million or more, which failure shall not have been remedied
within 30 days of the payment default that causes the aggregate amount of such
indebtedness to exceed $10 million, or (viii) the cessation of the full force
and effect of the Indenture, except as permitted therein. The Trustee may
withhold notice to the holders of the Senior Notes of any default or Event of
Default (except in payment of principal of, or premium, if any, or interest on
the Notes) if the Trustee considers it in the interest of the holders of the
Senior Notes to do so.
    
 
   
     If an Event of Default occurs and is continuing with respect to the
Indenture, the Trustee or the Holders of not less than 25% in principal amount
of the Senior Notes outstanding may, and at the request of the Holders, the
Trustee shall declare the principal of and premium, if any, and accrued but
unpaid interest on all the Senior Notes to be due and payable. Upon such a
declaration, such principal, premium, if any, and interest will be due and
payable immediately. If an Event of Default relating to certain events of
bankruptcy, insolvency or reorganization of the Company or any Material
Subsidiary occurs and is continuing, the principal of and premium, if any, and
interest on all the Senior Notes will become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any Holders
of the Senior Notes. If an Event of Default relating to item (iv) in the
preceding paragraph occurs, such acceleration will be automatically rescinded if
the Event of Default is cured by the Company or waived by the holders of the
relevant Indebtedness within 30 days after the occurrence of the Event of
Default. Under certain circumstances, the holders of a majority in principal
amount of the outstanding Senior Notes may rescind any such acceleration with
respect to the Senior Notes and its consequences.
    
 
     The Indenture provides that no Holder may pursue any remedy under the
Indenture unless (i) the Trustee shall have received written notice from the
Holder of a continuing Event of Default, (ii) the Trustee shall have received a
request from holders of at least 25% in principal amount of the Senior Notes to
pursue such remedy, (iii) the Trustee shall have been offered indemnity
reasonably satisfactory to it, (iv) the Trustee shall have failed to act for a
period of 60 days after receipt of such notice and offer of indemnity, and (v)
during such 60-day period, a majority of the Holders do not give the Trustee
directions inconsistent with the initial request; however, such provision does
not affect the right of a holder of a Note to sue for enforcement of any overdue
payment thereon.
 
     The holders of a majority in principal amount of the Senior Notes then
outstanding have the right to direct the time, method and place of conducting
any proceeding for exercising any remedy available to the Trustee under the
Indenture, subject to certain limitations specified in the Indenture. The
Indenture will require the annual filing by the Company with the Trustee of a
written statement as to compliance with the covenants contained in the
Indenture.

with respect to matters or questions arising under the Indenture which shall not

for cancellation or (ii) (A) the Senior Notes mature within one year or all of
them are to be called for redemption within one year under arrangements

redemption, as the case may be, and to pay all other sums payable by it under
the Indenture or the Senior Notes, (C) no Event of Default with respect to the
Senior Notes shall have occurred and be continuing on the date of such deposit,
(D) such deposit will not result in a breach or violation of, or constitute a
default under, the Indenture or any other agreement or instrument to which the
Company is a party or by which either is bound and (E) the Company has delivered
to the Trustee any required Officers' Certificate and Opinion of Counsel.

Its address is 101 East 5th Street, St. Paul, MN 55101.
    
 
     The Indenture contains certain limitations on the right of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any such
claim as security or otherwise. The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest (as defined in
the Trust Indenture Act of 1939), it must eliminate such conflict or resign.
 
     The Indenture provides that in case an Event of Default shall occur (and be
continuing), the Trustee will be required to use the degree of care and skill of
a prudent man in the conduct of his own affairs. The Trustee will be under no
obligation to exercise any of its powers under the Indenture at the request of
any of the holders of the Senior Notes, unless such holders shall have offered
the Trustee indemnity reasonably satisfactory to it.
 
AUTHENTICATION
 
     Two officers of the Company will sign each Senior Note on behalf of the
Company, in each case by manual or facsimile signature. The Company's seal will
be reproduced on each Senior Note and may be in facsimile form. A Senior Note
will not be valid until the Trustee or an Authenticating Agent manually signs
the certificate of authentication on the Senior Note. Each Senior Note will be
dated the date of its authentication.
 
                          DESCRIPTION OF CAPITAL STOCK
 
     The authorized capital stock of the Company consists of 1,200,000 shares of
Class A Common Stock, $.01 par value (the "Class A Common Stock "), 100,000,000
shares of Class B Common Stock, $.01 par value (the "Class B Common Stock"),
(such classes of Common Stock referred to collectively as the "Common Stock")
and 48,800,000 shares of preferred stock, $.01 par value (the "Preferred
Stock"). As of the Effective Date, there were 1,200,000 outstanding shares of
Class A Common Stock and 43,800,000 outstanding shares of Class B Common Stock.
 
     The material terms of the Company's capital stock are summarized below. The
following description is a summary only, however, and is not intended to be
complete and is qualified by reference to the provisions of the Company's
Restated Certificate of Incorporation (the "Certificate of Incorporation") and
bylaws and the agreements referred to in this summary description, copies of
each of which have been filed as exhibits to the Registration Statement of which
this Prospectus is a part. As used in this section, except as otherwise stated
or required by context, each reference to AmWest includes any successor by
merger, liquidation, consolidation or similar transaction and any wholly owned
subsidiary of such entity or such successor.
 
COMMON STOCK -- ALL CLASSES
 
     Holders of Common Stock of all classes participate equally as to any
dividends or distributions on the Common Stock, except that dividends payable in
shares of Common Stock, or securities to acquire Common Stock, are paid in
Common Stock, or securities to acquire Common Stock, of the same class as that
held by the recipient of the dividend. Upon any liquidation, dissolution or
winding up of the Company, holders of Common Stock of all outstanding classes
are entitled, subject to the rights of preferred Stockholders, if any, to
receive pro rata all of the assets of the Company available for distribution to
the stockholders. Holders of Common Stock have no preemptive, subscription,
conversion or redemption rights (other than conversion rights of AmWest and GPA
described below), and are not subject to further calls or assessments. Holders
of Common Stock have no right to cumulate their votes in the election of
directors. The Common Stock votes together as a single class, subject to the
right to a separate class vote in certain instances required by law.
 
                                       66
<PAGE>   69
 
CLASS B COMMON STOCK AND CLASS A COMMON STOCK
 
     The holders of Class B Common Stock are entitled to one vote per share, and
the holders of Class A Common Stock are entitled to fifty votes per share, on
all matters submitted to a vote of common stockholders, except that voting
rights of non-U.S. citizens are limited as set forth below under "-- Limitation
on Voting by Foreign Owners."
 
     As set forth under the heading "Principal Stockholders," AmWest currently
owns in the aggregate 100% of the outstanding Class A Common Stock and   % of
the outstanding Class B Common Stock, which collectively represent approximately
  % of the total voting power of the outstanding Common Stock. In addition,
AmWest holds Warrants to acquire an additional 2,769,231 shares of Class B
Common Stock that, if exercised, would increase AmWest's voting control to   %.
See "Principal Stockholders -- Stockholders' Agreement" below for a discussion
of arrangements regarding the composition of the Board of Directors of the
Company.
 
   
     Holders of Class A Common Stock may at any time elect to convert such
shares into an equal number of shares of Class B Common Stock. Class B Common
Stock is not convertible into Class A Common Stock.
    
 
PREFERRED STOCK
 
     Pursuant to the Company's Certificate of Incorporation, the Company is
authorized to issue 48,800,000 shares of Preferred Stock. The Company's Board of
Directors by resolution may authorize the issuance of the Preferred Stock as a
class, in one or more series, having the number of shares, designations,
relative voting rights, dividend rights, liquidation and other rights
preferences, and limitations that the Board of Directors fixes without any
stockholder approval. No shares of Preferred Stock have been issued.
 
LIMITATION ON VOTING BY FOREIGN OWNERS
 
     The Certificate of Incorporation defines "Foreign Ownership Restrictions"
as "applicable statutory, regulatory and interpretive restrictions regarding
foreign ownership or control of U.S. air carriers (as amended or modified from
time to time)." Such restrictions currently require that no more than 25% of the
voting stock of the Company be owned or controlled, directly or indirectly, by
persons who are not U.S. citizens ("Foreigners") for purposes of the Foreign
Ownership Restrictions, and that the Company's president and at least two-thirds
of its directors be U.S. citizens. The Certificate of Incorporation provides
that no shares of capital stock may be voted by or at the direction of
Foreigners, unless such shares are registered on a separate stock record (the
"Foreign Stock Record"). The Company's bylaws further provide that no shares
will be registered on the Foreign Stock Record if the amount so registered would
exceed the Foreign Ownership Restrictions. Registration on the Foreign Stock
Record is made in chronological order based on the date the Company receives a
written request for registration.
 
LIMITATION OF DIRECTOR LIABILITY AND INDEMNIFICATION
 
     The Company's Certificate of Incorporation and Restated Bylaws
(collectively, the "Charter Documents") provide, to the fullest extent permitted
by Delaware law as it may from time to time be amended, that no director shall
be liable to the Company or any stockholder for monetary damages for breach of
fiduciary duty as a director. Delaware law currently provides that such waiver
may not apply to liability (i) for any breach of the director's duty of loyalty
to the Company or its stockholders, (ii) for acts or omissions not in good faith
or which involve intentional misconduct or a knowing violation of law, (iii)
under Section 174 of the Delaware General Corporation Law (governing
distributions to stockholders), or (iv) for any transaction from which the
director derived any improper personal benefit. The Charter Documents further
provide that the Company will indemnify each of its directors and officers to
the full extent permitted by Delaware law and may indemnify certain other
persons as authorized by law.
 
     Additionally, America West has entered into written agreements with each
person who served as a director or executive officer of America West as of the
date of the Investment Agreement providing for similar indemnification of such
person and that no recourse or liability whatsoever with respect to the
Investment
 
                                       67
<PAGE>   70
 
Agreement, the Plan or consummation of the transactions contemplated thereby
shall be had by or in the right of America West against such person.
 
DELAWARE BUSINESS COMBINATION STATUTE
 
     Pursuant to the Plan, the Company has elected not to be governed by Section
203 of the Delaware General Corporation Law ("DGCL"). In general, Section 203 of
the DGCL prohibits a Delaware corporation from entering into a "business
combination" with an "interested stockholder" for a period of three years unless
certain exceptions are applicable. Pursuant to the statute, the Company's
election not to be governed by Section 203 will not become effective until the
first anniversary date of the Effective Date.
 
     By opting out of Section 203, America West may be foregoing certain
"anti-takeover" protections that may otherwise be available to it under Section
203 in the event of an unsolicited takeover offer from a party other than
AmWest. However, given the limited protections provided by Section 203, the
significant holdings of Common Stock by AmWest after the Effective Date and
certain other factors, the Company does not believe that the protections
afforded by Section 203 are very significant or that an unsolicited takeover
offer is likely to occur.
 
     With respect to a possible "business combination" or takeover attempt by
AmWest or its affiliates involving the Company, the protective provisions of
Section 203 would not apply to such a transaction because the Board of Directors
of the Company has previously approved of the transactions contemplated by the
Investment Agreement and otherwise described herein prior to the date such
agreement was entered into and prior to the date that AmWest acquired any shares
of Common Stock. However, pursuant to the Stockholders' Agreement, AmWest will
be precluded from consummating any "Business Combination" (as defined in the
Stockholders Agreement) with the Company for a three-year period commencing on
the Effective Date, unless such transaction is recommended or approved in
advance by at least three Independent Directors or a majority of the Common
Stock of the Company not held by AmWest and its affiliates.
 
                            DESCRIPTION OF WARRANTS
 
GENERAL
 
   
     The Warrants will be issued under a Warrant Agreement dated on or about
August   , 1994 (the "Warrant Agreement") between the Company and First
Interstate of California, N.A. as warrant agent (the "Warrant Agent"). The
material terms of the Warrants and the Warrant Agreement are summarized below.
The statements under this caption relating to the Warrants and the Warrant
Agreement are summaries only, however, and do not purport to be complete. Such
summaries make use of terms defined in the Warrant Agreement and are qualified
in their entirety by express reference to the Warrant Agreement, which has been
filed as an exhibit to the Registration Statement of which this Prospectus is a
part. All section references under this heading are references to sections of
the Warrant Agreement.
    
 
     Each of the 4,153,846 Warrants offered hereby entitles the registered
holder to purchase from the Company one share of Class B Common Stock for
$        , subject to adjustment as provided in the Warrant Agreement, at any
time after the Effective Date and before the fifth anniversary of the Effective
Date (the "Expiration Date"). (Section 3.01)
 
CERTAIN TERMS OF THE WARRANTS
 
     Exercise of Warrants.  Warrants may be exercised by surrendering the
Warrant Certificate evidencing such Warrants at the Warrant Agent's Office with
the Election to Exercise form duly completed and executed. Surrendered Warrant
Certificates must be accompanied by payment in full to the Warrant Agent for the
account of the Company (i) in cash, (ii) by certified or official bank check or
(iii) by any combination of (i) or (ii) the Warrant Price for each share of
Class B Common Stock as to which Warrants are exercised and any applicable taxes
that the Company is not required to pay as set forth in Sections 4.08 or 6.01.
(Section 3.02(a)).
 
                                       68
<PAGE>   71
 
     The Company will not be required to issue fractional shares of Class B
Common Stock upon the exercise of the Warrants. In lieu thereof, the Company, at
its option, may purchase the fraction for an amount in cash equal to the
then-current market value of the fraction (as defined in Section 4.01(d)) or
issue scrip of the Company that is non-dividend bearing and non-voting and
exchangeable in combination with other similar scrip for the number of full
shares of Class B Common Stock represented thereby. (Section 3.03)
 
     The Company has the right, except as limited by law or other agreement, to
purchase or otherwise acquire Warrants at such times, in such manner and for
such consideration as it may deem appropriate. (Section 3.04)
 
     The Company will, at all times, reserve and keep available free of
preemptive rights out of its authorized and unissued Class B Common Stock, the
full number of shares of Class B Common Stock, if any, issuable if all
outstanding Warrants then exercisable were to be exercised. Any shares of Class
B Common Stock issued upon a Warrant holder's exercise of any Warrant shall be
validly authorized and issued, fully paid, non-assessable, free of preemptive
rights and free from all taxes (other than those required to be paid by the
holder or its transferees) liens, charges, security interests and claims created
or incurred by the Company in respect of the issuance thereof. (Sections
3.02(b); 4.06)
 
     Adjustment of Warrant Price.  The Warrant Price and the number of shares of
Class B Common Stock purchasable upon exercise of each Warrant are subject to
adjustment in certain events, including (a) the payment of a dividend in Common
Stock or certain combinations, subdivisions, or reclassifications of the Common
Stock, (b) the issuance to holders of Common Stock (without any charge to such
holders) of rights, options or warrants entitling the holders thereof to
purchase Common Stock (or securities convertible into Common Stock) at a price
per share less than the then-current market price per share, and (c) certain
distributions by the Company to holders of Common Stock of evidences of its
indebtedness or assets (excluding any cash dividend or distribution out of
retained earnings), all as described in the Warrant Agreement. The Company is
not required to make any adjustment to the Warrant Price unless such adjustment
could require an increase or decrease of at least $     in the Warrant Price
then subject to adjustment; provided, however, that any adjustments that are not
made for this reason must be carried forward and taken into account in any
subsequent adjustment. (Section 4.01) The Company may, at its option, reduce the
Warrant Price at any time.
 
     Rights Upon Consolidation, Merger, Sale, Transfer or Reclassification.  In
the event of certain consolidations with or mergers of the Company into another
corporation or in the event of certain leases, sales or conveyances of the
property of the Company to another corporation, the holder of each outstanding
Warrant shall have the right to receive, upon exercise of the Warrant, the kind
and amount of shares, securities, property or cash receivable upon such
consolidation, merger, lease, sale or conveyance by a holder of one share of
Class B Common Stock. (Section 4.05(a))
 
     In the event of any liquidation, dissolution or winding up of the affairs
of the Company, each holder of a Warrant may receive, upon exercise of such
Warrant in accordance with the Warrant Agreement, the same kind and amount of
any stock, securities or assets as may be issuable, distributable or payable on
any such dissolution, liquidation, or winding up with respect to each share of
Class B Common Stock of the Company. (Section 4.05(b))
 
     In the event of certain reclassifications or changes of the shares of Class
B Common Stock issuable upon exercise of the Warrants or in the event of the
consolidation or merger of another corporation into the Company in which the
Company is the continuing corporation in which the holders of the shares of
Common Stock thereafter receive shares, other securities, property or cash for
such shares of Common Stock, each holder of a Warrant shall have the right to
receive, upon exercise of the Warrant, the kind and amount of shares, other
securities, property or cash receivable upon such reclassification or change.
(Section 4.05(c))
 
     Rights as Warrantholders.  A holder of Warrants does not have any rights
whatsoever as a stockholder of the Company, either at law or equity, including
but not limited to the right to vote at, or to receive notice of, any meeting of
stockholders of the Company. The consent of any holder is not required with
respect to any action or proceeding of the Company nor do holders, by reason of
the ownership or possession of a Warrant,
 
                                       69
<PAGE>   72
 
have any right to receive any cash dividends, stock dividends, allotments or
rights, or other distributions paid, allotted or distributed or distributable to
the stockholders of the Company. A holder of a Warrant shall not have any rights
unless the right is expressly conferred by the Warrant Agreement or by a Warrant
Certificate held by the holder. (Section 5.01)
 
                              PLAN OF DISTRIBUTION
 
   
     Selling Securityholders may sell their Securities in transactions through
such underwriters, brokers, dealers or agents as may be approved by the Company
from time to time or through privately negotiated transactions; provided,
however, that pursuant to the Stockholders' Agreement, certain of the Selling
Securityholders have agreed that (i) they will not dispose of any Common Stock
(other than to an affiliate of the transferor) if, after giving effect thereto
and to any concurrent transaction, the total number of shares of Class B Common
Stock owned by the transferor is less than 200% of the total number of shares of
Class A Common Stock beneficially owned by the transferor; provided, however,
that the preceding will not prohibit any person from transferring or otherwise
disposing of all shares of Common Stock owned by such person; (ii) all of the
Securities issued to the Selling Securityholders shall bear the legend that the
Securities may not be sold, transferred or otherwise disposed of except in
accordance with applicable securities laws and the terms of the Plan; and (iii)
AmWest has agreed that subject to certain exceptions it will not, prior to
August   , 1997, sell in a single transaction or related transaction 51% or more
of the combined voting power of all shares of Common Stock then outstanding
unless other holders of Common Stock shall have been given a reasonable
opportunity to participate therein on a pro rata basis and at the same price per
share and on the same economic terms and conditions applicable to AmWest. See
"Principal Stockholders -- Stockholders' Agreement."
    
 
   
     The distribution of the Securities may be effected from time to time in one
or more transactions (which may involve crosses or block transactions) (i) in
the over-the-counter market, (ii) in transactions otherwise than in the
over-the-counter market or (iii) through the writing of options on the
Securities (whether such options are listed on an options exchange or
otherwise). Any of such transactions may be effected at market prices prevailing
at the time of sale, at prices related to such prevailing market prices, at
negotiated prices or at fixed prices. If the Selling Securityholders effect such
transactions by selling Securities to or through underwriters, dealers or
agents, such underwriters, dealers or agents may receive compensation in the
form of discounts, concessions or commissions from the Selling Securityholders
or commissions from purchasers of Securities for whom they may act as agent
(which discounts, concessions or commissions as to a particular underwriters,
dealers or agents might be in excess of those customary in the types of
transactions involved). The Selling Securityholders and any underwriters,
brokers, dealers or agents that participate in the distribution of the
Securities might be deemed to be underwriters and any profit on the sale of
Securities by them and any discounts, concessions or commissions received by any
such underwriters, brokers, dealers or agents might be deemed to be underwriting
discounts and commissions under the Securities Act. The Company will not receive
any of the proceeds from the sale of any of the Securities by the Selling
Securityholders.
    
 
   
     At the time a particular offer of Securities is made, a Prospectus
Supplement, to the extent required, will be distributed which will set forth the
aggregate amount and type of Securities being offered, the names of the Selling
Securityholders, the purchase price, the amount of expenses of the offering and
the terms of the offering, including the name or names of any underwriters,
brokers, dealers or agents, any discounts, commissions and other items
constituting compensation from the Selling Securityholders and any discounts,
commissions or concessions allowed or reallowed or paid to dealers.
    
 
   
     Under the Exchange Act and applicable rules and regulations promulgated
thereunder, any person engaged in a distribution of any of the Securities may
not simultaneously engage in market making activities with respect to the
Securities for a period, depending upon certain circumstances, of either two
days or nine days prior to the commencement of such distribution. In addition
and without limiting the foregoing, the Selling Securityholders will be subject
to applicable provisions of the Exchange Act and the rules and regulations
promulgated thereunder, including without limitation Rules 10b-6 and 10b-7,
which provisions may limit the timing of purchases and sales of any of the
Securities by the Selling Securityholders.
    
 
                                       70
<PAGE>   73
 
     Under the securities laws of certain states, the Securities may be sold in
such states only through registered or licensed brokers or dealers. In addition,
in certain states the Securities may not be sold unless the Securities have been
registered or qualify for sale in such state or an exemption from registration
or qualification is available and is complied with.
 
   
     Prior to this offering, there has been no public market for the Securities.
Application has been made to list the Class B Common Stock and the Warrants on
the New York Stock Exchange. No assurance can be given as to whether an active
trading market will develop for the Securities. All of the foregoing may affect
the marketability of the Securities and the ability of broker-dealers to engage
in market making activities with respect to the Securities. See "Investment
Considerations -- Limited Trading Market; Shares Eligible for Future Sale."
    
 
                                 LEGAL MATTERS
 
   
     The validity of the shares of Common Stock and certain legal matters
relating to the Senior Notes and Warrants offered hereby will be passed upon for
the Company by Andrews & Kurth L.L.P., Houston, Texas.
    
 
                                    EXPERTS
 
     The financial statements and schedules of America West Airlines, Inc., as
of December 31, 1993 and 1992, and for each of the years in the three-year
period ended December 31, 1993, have been included herein and in the
registration statement in reliance upon the reports of KPMG Peat Marwick,
independent certified public accountants, appearing elsewhere herein, and upon
the authority of said firm as experts in accounting and auditing.
 
     The reports of KPMG Peat Marwick covering the December 31, 1993 financial
statements and schedules contain an explanatory paragraph that states that the
Company's Chapter 11 proceeding, significant losses, accumulated deficit and
highly leveraged capital structure raise substantial doubt about its ability to
continue as a going concern. The financial statements and schedules do not
include any adjustments that might result from the outcome of these
uncertainties.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
    
   
                                 JUNE 30, 1994
    
 
   
1. REORGANIZATION UNDER CHAPTER 11, LIQUIDITY AND FINANCIAL CONDITION
    
 
   
     On August 10, 1994, the United States Bankruptcy Court for the District of
Arizona (the "Bankruptcy Court") confirmed the Company's Plan of Reorganization
("Plan"). The Company currently anticipates that the Plan will be effective
after expiration of the Bankruptcy Code 10-day appeal period on or about August
23, 1994 (the "Effective Date").
    
 
   
     In connection with the confirmation hearing on August 10, 1994, the Company
filed certain motions with the Bankruptcy Court to secure approval to pay the
following confirmation bonuses or success fees:
    
 
   
     -- $9.3 million to be paid based upon length of service to non-officer
employees.
    
 
   
     -- $1.2 million to be paid to officers and other members of management.
    
 
   
     -- 125,000 shares of stock in the reorganized Company to be issued to the
        Company's Chairman and Chief Executive Officer.
    
 
   
     A hearing on these motions has been scheduled for August 24, 1994.
    
 
   
HISTORICAL CHAPTER 11 EVENTS AND EVENTS LEADING TO PLAN CONFIRMATION
    
 
   
     On June 27, 1991, the Company filed a voluntary petition in the United
States Bankruptcy Court for the District of Arizona to reorganize under Chapter
11 of the United States Bankruptcy Code (the "Bankruptcy Code"). The Company is
currently operating as a debtor-in-possession ("D.I.P.") under the supervision
of the Bankruptcy Court. As a debtor-in-possession, the Company is authorized to
operate its business but may not engage in transactions outside its ordinary
course of business without the approval of the Bankruptcy Court.
    
 
   
     Subject to certain exceptions under the Bankruptcy Code, the Company's
filing for reorganization automatically enjoined the continuation of any
judicial or administrative proceedings against the Company. Any creditor actions
to obtain possession of property from the Company or to create, perfect or
enforce any lien against the property of the Company are also enjoined. As a
result, the creditors of the Company are precluded from collecting pre-petition
debts without the approval of the Bankruptcy Court.
    
 
   
     The Company had the exclusive right for 120 days after the Chapter 11
filing on June 27, 1991 to file a plan of reorganization and 60 additional days
to obtain necessary acceptances of such plan. Such periods were extended at the
discretion of the Bankruptcy Court, but only on a showing of good cause. On May
17, 1994, the Company filed a Disclosure Statement with the Bankruptcy Court
which includes its Plan of Reorganization. On June 28, 1994, the Bankruptcy
Court approved the adequacy of the Disclosure Statement and set into motion a
balloting process for the approval of the Plan of Reorganization. Subject to
certain exceptions set forth in the Bankruptcy Code, acceptance of a Plan of
Reorganization requires approval of the Bankruptcy Court and the affirmative
vote (i.e. 50 percent of the number and 66 2/3 percent of the dollar amount) of
each class of creditors and equity holders whose claims are impaired by the
plan. (See "Plan of Reorganization" for further discussion of the contents of
the Plan of Reorganization).
    
 
   
     Certain pre-petition liabilities have been paid after obtaining the
approval of the Bankruptcy Court, including certain wages and benefits of
employees, insurance costs, obligations to foreign vendors and governmental
agencies, travel agent commissions and ticket refunds. The Company has also been
allowed to honor all tickets sold prior to the date it filed for reorganization.
In addition, the Company is authorized to pay pre-petition liabilities to
essential suppliers of fuel, food and beverages and to other vendors providing
critical goods and services. Subsequent to filing and with the approval of the
Bankruptcy Court, the Company assumed certain executory contracts of essential
suppliers.

             NOTES TO CONDENSED FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
     Parties to executory contracts may, under certain circumstances, file
motions with the Bankruptcy Court to require the Company to assume or reject
such contracts. Unless otherwise agreed, the assumption of a contract will
require the Company to cure all prior defaults under the related contract,
including all pre-petition liabilities. Unless otherwise agreed, the rejection
of a contract is deemed to constitute a breach of the agreement as of the moment
immediately preceding the Chapter 11 filing, giving the other party to the
contract a right to assert a general unsecured claim for damages arising out of
the breach.
    
 
   
     February 28, 1992 was set as the last date for the filing of proofs of
claim under the Bankruptcy Code and the Company's creditors have submitted
claims for liabilities not paid and for damages incurred. There may be
differences between the amounts at which any such liabilities are recorded in
the financial statements and the amount claimed by the Company's creditors. In
connection with the confirmation of the Company's Plan of Reorganization, the
Bankruptcy Court will be requested to fix the total amount of allowed claims as
well as the total amount of disputed claims that may become allowed claims.
    
 
   
     The Company has incurred and will continue to incur significant costs
associated with the reorganization. The amount of these costs, which are being
expensed as incurred, is expected to significantly affect the results of
operations.
    
 
   
     As a result of its filing for protection under Chapter 11 of the Bankruptcy
Code, the Company is in default of substantially all of its debt agreements. All
outstanding pre-petition unsecured debt of the Company has been presented in
these financial statements within the caption Estimated Liabilities Subject to
Chapter 11 Proceedings.
    
 
   
     Additional liabilities subject to the proceedings may arise in the future
as a result of the rejection of executory contracts, including leases, and from
the determination by the Bankruptcy Court (or agreement by parties in interest)
of allowed claims for contingencies and other disputed amounts. Conversely, the
assumption of executory contracts and unexpired leases may convert liabilities
shown as subject to Chapter 11 proceedings to post-petition liabilities.
    
 
   
     Substantially all of the aircraft, engines and spare parts in the Company's
fleet are subject to lease or secured financing agreements that entitle the
Company's aircraft lessors and secured creditors to rights under Section 1110 of
the Bankruptcy Code. Pursuant to Section 1110, the Company had 60 days from the
date of its Chapter 11 filing, or until August 26, 1991, to bring its
obligations to these aircraft lessors and secured creditors current and/or reach
other mutually satisfactory negotiated arrangements. In September 1991, as a
condition to the borrowings under the initial $55 million D.I.P. facility, the
Company arranged for rent, principal and interest payment deferrals from a
majority of its aircraft providers as a condition to the assumption of the
related lease or secured borrowing by the Company. As a result of these
arrangements, the Company was able to assume the executory contracts associated
with 83 aircraft in its fleet without having to bring its obligations to these
aircraft providers current. In addition, as part of the initial D.I.P. facility,
the Company assumed and brought current certain agreements for 16 Airbus A320
aircraft, three CFM engines, a Boeing 757-200 and a Boeing 737-300.
    
 
   
     Twenty-two aircraft were deemed surplus to the Company's needs and the
associated executory contracts were rejected. Included in 1991 reorganization
costs was $35.2 million in write-offs of leasehold improvements, security
deposits, accrued maintenance, accrued rents and other costs to return the
aircraft which were subject to the rejected aircraft agreements. In certain
cases, final agreements were reached with such aircraft providers and no further
claims by such providers will be pursued as a result of the rejections. In other
instances, the aircraft providers have filed claims in the normal course of the
bankruptcy and as of June 30, 1994, significant claims for rejected aircraft
have not yet been settled.
    
 
   
     Due to the uncertain nature of many of the potential claims, the Company is
unable to project the magnitude of such claims with any degree of certainty.
However, the claims (pre-petition claims and administrative claims) that have
been filed against the Company are in excess of $2 billion. Such aggregate
    
 
                                       F-7

amount includes claims of all character, including, but not limited to,
unsecured claims, secured claims, claims that have been scheduled but not filed,
duplicative claims, tax claims, claims for leases that were assumed, and claims
which the Company believes to be without merit; however, claims filed for which
an amount was not stated, are not reflected in such amount. The Company is
unable to estimate the potential amount of such unstated claims; however, the
amount of such claims could be material.
    
 
   
     The Company is in the process of reviewing and seeking allowance or
disallowance, as appropriate, of the general unsecured claims asserted against
the Company. In many instances, such allowance process will include the
commencement of Bankruptcy Court proceedings in order to determine the amount at
which such claims should be allowed. The Company has accrued its estimate of
claims that will be allowed or the minimum amount at which it believes the
asserted general unsecured claims will be allowed if there is no better estimate
within the range of possible outcomes. However, the ultimate amount of allowed
claims will be different and such differences could be material. In its
Disclosure Statement, the Company estimates the range of allowed general
unsecured claims to be from a low of approximately $300 million to a high of
approximately $360 million. This range does not include, nor can the Company
currently estimate, claims which may arise and be allowed as a result of the
renegotiation of certain aircraft purchase agreements.
    
 
   
     The Bankruptcy Code requires that all administrative claims be paid on the
effective date of a plan of reorganization unless the respective claimants
agreed to different treatment. The Company is actively negotiating with
claimants to achieve mutually acceptable dispositions of these claims. Since the
commencement of the bankruptcy proceeding, claims alleging administrative
expense priority totaling more than $153 million have been filed. As of June 30,
1994, $115 million of the filed claims have been allowed and settled for $50.2
million in the aggregate. Additionally, the Company has obtained Bankruptcy
Court approval of an agreement which settled the remaining $38 million filed
administrative expense claim (which relates to a rejected lease of a Boeing
737-300 aircraft) for $5 million. Pursuant to an order dated May 18, 1994, the
Bankruptcy Court fixed July 1, 1994 as the bar date for filing such
administrative claims. In response to the notice of this bar date, certain
claims were filed asserting status as non-ordinary course administrative expense
claims. These include claims for administrative rent, breach of return
conditions on aircraft, guarantees and obligations under tax indemnity
agreements. The amount of such asserted claims, if allowed, could be material;
however, the Company is optimistic that the claims, except to the extent
previously known and provided for by the Company, will be either disallowed,
withdrawn or negotiated to a mutually acceptable amount.
    
 
   
PLAN OF REORGANIZATION
    
 
   
     On December 8, 1993 and February 16, 1994, the Bankruptcy Court entered
certain orders which provided for a procedure through which interested parties
could submit proposals to participate in a plan of reorganization for America
West. The Bankruptcy Court also set February 24, 1994 as the date for America
West to select a "Lead Plan Proposal" from the proposals submitted.
    
 
   
     On February 24, 1994, America West selected as its Lead Plan Proposal an
investment proposal submitted by AmWest Partners, L.P., a limited partnership
("AmWest"), which includes TPG Partners, L.P., Continental Airlines, Inc. and
Mesa Airlines, Inc. Certain funds managed or advised by Fidelity Management
Trust Company and its affiliates and Lehman Brothers, Inc. are participating in
the proposal as assignees of AmWest. On March 11, 1994, the Company and AmWest
entered into an Investment Agreement which was filed with the Bankruptcy Court
on March 11, 1994 (the "Original Investment Agreement"). The Original Investment
Agreement was superseded by a Revised Investment Agreement dated as of March 11,
1994 and filed with the Bankruptcy Court on March 28, 1994 (the "Revised
Investment Agreement"). The Revised Investment Agreement was superseded by a
Second Revised Investment Agreement dated as of April 7, 1994 and filed with the
Bankruptcy Court on April 8, 1994 (the "Second Revised Investment Agreement").
The Second Revised Investment Agreement was superseded by a Third Revised
Investment

Agreement dated as of April 21, 1994 and filed with the Bankruptcy Court on
April 26, 1994 (the "Third Revised Investment Agreement"). The Third Revised
Investment Agreement is substantially identical to the Second Revised Investment
Agreement except for a change in the configuration of the expanded 15-member
board of directors of the Company. The Third Revised Investment Agreement
substantially incorporates the terms of the AmWest investment proposal. It
provides that AmWest will purchase from America West equity securities
representing a 33.5 percent ownership interest (subject to adjustment) in the
Company for $114.8 million and $100 million in new senior unsecured debt
securities. The Third Revised Investment Agreement also provides that, in
addition to the 33.5 percent ownership interest in the Company, AmWest would
also obtain 71.2 percent of the total voting interest (subject to adjustment) in
America West after the Company is reorganized. The terms of the Third Revised
Investment Agreement have been incorporated into a Plan of Reorganization which
was filed with the Bankruptcy Court on May 17, 1994. By Order dated June 28,
1994, the Bankruptcy Court approved the Company's Disclosure Statement, finding
that it contained adequate information as required by Section 1125 of the
Bankruptcy Code. The Bankruptcy Court also entered an order fixing August 3,
1994 as the last date for filing objections to confirmation of the Plan of
Reorganization, voting to accept or reject the Plan and making any available
elections under the Plan. In addition, the Court fixed August 10, 1994 as the
hearing date for confirmation of the Plan of Reorganization. Consummation of the
Plan of Reorganization is subject to satisfaction of the closing conditions
specified therein, including (among others) the accuracy of certain
representations and warranties of the Company and the absence of any material
adverse change in the Company's condition (financial or otherwise), business,
assets, properties, operations or relations with employees or labor unions since
December 31, 1993.
    
 
   
     In addition to the interest in the reorganized America West that would be
acquired by AmWest pursuant to the Plan of Reorganization, the Plan also
provides for the following:
    
 
   
     1. The D.I.P. financing would be repaid in full with cash on the date the
Plan of Reorganization is effective ("Effective Date") or on such other terms as
may be agreed to.
    
 
   
     2. On the Effective Date, unsecured creditors would receive 59.5 percent of
the new common equity in the reorganized Company. In addition, unsecured
creditors would have the right to elect to receive cash at $8.889 per share up
to an aggregate maximum amount of $100 million, through a purchase by AmWest of
the shares otherwise allocable to such unsecured creditors making the election
under the Plan of Reorganization.
    
 
   
     3. Holders of common stock equity interests would receive 5 percent of the
new common equity of the Company. In addition, such holders of equity interests
would have the right to subscribe to purchase up to 1,615,179 shares of the new
Class B common stock of the Company for $8.889 per share from AmWest, and would
also receive warrants entitling them to purchase 6,230,769 shares of the
reorganized Company's common stock. With respect to establishing the price of
the warrants, the Bankruptcy Court will be requested to fix the total amount of
allowed unsecured claims as well as the total amount of disputed claims that may
become allowed claims. In turn, the aggregate amount established by the
Bankruptcy Court would be multiplied by 1.1 and the resultant product divided by
the number of shares of new common equity to be issued to unsecured creditors
(26,775,000 shares) to establish the price. Holders of preferred stock equity
interests would receive $500,000 cash and the right to subscribe to the purchase
of the first 250,000 shares of the over-subscription stock otherwise allocable
to holders of common stock equity interests.
    
 
   
     4. In exchange for certain concessions principally arising from
cancellation of the right of Guinness Peat Aviation ("GPA") affiliates to put to
America West 10 Airbus A320 aircraft at fixed rates, GPA, or certain affiliates
thereof, would receive (i) 2.0 percent of the new common equity in the
reorganized Company, (ii) warrants to purchase up to 1,384,615 shares of the
reorganized Company's common stock on the same terms as the AmWest warrants,
(iii) $30.5 million in cash, and (iv) the right to require the Company to lease
from GPA prior to June 30, 1999 up to eight aircraft of types operated by the
Company on terms which the Company believes to be more favorable than those
currently applicable to the put aircraft. (See Note 8(c) for further discussion
of the new put agreement.)

             NOTES TO CONDENSED FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
     5. Continental Airlines, Inc., Mesa Airlines, Inc. and America West would
enter into certain alliance agreements which would include code-sharing,
schedule coordination and certain other relationships and agreements. A
condition precedent to the Effective Date of the Plan of Reorganization is that
these agreements be in form and substance satisfactory to America West,
including the Company's reasonable satisfaction that such alliance agreements
when fully implemented will result in an increase in pre-tax income of not less
that $40 million per year.
    
 
   
     6. The expansion of the Company's board of directors to 15 members for a
period not less than three years following effective date. Nine members would be
designated by AmWest and other members reasonably acceptable to AmWest would
include three members designated by the Creditors' Committee, one member
designated by the Equity Committee, one member designated by the Company's
current board of directors and one member designated by GPA.
    
 
   
     7. The pre-petition executory contract for the purchase of 24 A320-200
aircraft between the Company and AVSA would be amended to provide the Company
with greater flexibility, reduced pricing and enhanced terms for the acquisition
of the aircraft than is presently provided in the contract. Under the modified
terms, delivery dates of the aircraft would fall in the years 1998 through 2000
with an option to further defer deliveries. In addition, if A320 aircraft are
delivered as a result of the new GPA Put Agreement (see item 4 above), the
Company would have the right to cancel on a one-for-one basis, up to a maximum
of eight non-consecutive aircraft deliveries hereunder, subject to certain
conditions. In exchange for these modifications, the contract, as modified,
would be assumed and certain promissory notes relating thereto would be
reinstated on the Effective Date of the Plan of Reorganization.
    
 
   
     8. The Plan of Reorganization also provides for many other matters,
including the disposition of the various types of claims asserted against the
Company, the adherence to the Company's aircraft lease agreements, the
renegotiation, assumption as modified or rejection of certain pre-petition
aircraft purchase agreements and release of the Company's employees from all
obligations presently existing under the notes issued in connection with the
Company's employee stock purchase plan, concurrent with abandonment of such
notes by the Company and the cancellation of the shares of Company stock
securing such notes.
    
 
   
     In connection with the selection of AmWest's proposal as the Lead Plan
Proposal and pursuant to an order of the Bankruptcy Court, America West and
AmWest entered into an Interim Procedures Agreement setting forth, among other
things, the rights and obligations of AmWest and America West pending
Confirmation of the Plan of Reorganization. After a series of hearings, and
certain modifications, a Third Revised Interim Procedures Agreement (the
"Interim Procedures Agreement") was approved by the Bankruptcy Court on May 4,
1994. Among other terms governing the relationship of America West and AmWest
and its partners until the Effective Date of the Plan of Reorganization, the
Interim Procedures Agreement provides, subject to certain exceptions, that
America West is prohibited from directly soliciting additional investment
proposals. However, the Interim Procedures Agreement provides that, until an
order approving a Disclosure Statement is entered, America West may consider
unsolicited proposals subject to certain rights of AmWest to match any
alternative proposal. If America West accepts any such alternative proposal, or
a competing plan of reorganization proposed by another party in interest is
confirmed by the Bankruptcy Court, the Interim Procedures Agreement provides
that AmWest may apply to the Bankruptcy Court, on a substantial contribution
basis consistent with Section 503(b) of the Bankruptcy Code for recovery of an
additional amount not to exceed $4 million as reasonable compensation for its
actions in connection with the proposed investment in America West and the
benefits it provided to America West and its constituents in connection
therewith and with the Chapter 11 Case, provided, however, that making the
proposed investment will not, in and of itself, entitle AmWest to any additional
payment. Further, should America West breach the Interim Procedures Agreement at
any time, AmWest has agreed that any damages it may be entitled to recover shall
be limited to an amount not to exceed $4 million, subject to the approval of the
Bankruptcy Court. Upon the entry of an order by the Bankruptcy Court approving
the Disclosure Statement, America

             NOTES TO CONDENSED FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
West has agreed not to consider any other proposals. (An order approving the
Disclosure Statement was entered by the Bankruptcy Court on June 28, 1994.)
    
 
   
     The Interim Procedures Agreement also provides that America West will
reimburse AmWest for all out-of-pocket and third-party expenses actually
incurred by AmWest through February 28, 1994, subject to a cap of $550,000. The
Interim Procedures Agreement also provides for America West to reimburse AmWest
for expenses covered under the Interim Procedures Agreement and incurred by
AmWest on and after March 1, 1994 in an amount of up to $300,000 per month,
provided that any unused portion of such $300,000 for any month shall accumulate
and be carried forward and be available in any subsequent month, through the
Effective Date of the Plan of Reorganization. On the Effective Date, America
West will be obligated to reimburse AmWest for all expenses covered under the
Interim Procedures Agreement, irrespective of the foregoing monthly limitations.
All such fees will be subject to final approval of the Bankruptcy Court.
    
 
   
     On June 28, 1994, the Bankruptcy Court entered an order fixing August 3,
1994, as the last date for filing objections to confirmation of the Plan of
Reorganization, voting to accept or reject the Plan of Reorganization and making
any applicable elections available under the Plan. Additionally, the Court fixed
August 10, 1994, as the hearing date for confirmation of the Plan of
Reorganization. The Plan of Reorganization must be approved by the Bankruptcy
Court and by specified majorities of each class of creditors and equity holders
whose claims are impaired by the Plan. Alternatively, absent the requisite
approvals, the Company may seek Bankruptcy Court approval of its Reorganization
Plan under Section 1129(b) of the Bankruptcy Code, assuming certain tests are
met.
    
 
   
     If at any time the Creditors Committee, the Equity Committee or any
creditor of the Company or equity holder of the Company believes that the
Company is or will not be in a position to sustain operations, such party can
move in the Bankruptcy Court to compel a liquidation of the Company's estate by
conversion to Chapter 7 bankruptcy proceedings or otherwise. In the event that
the Company is forced to sell its assets and liquidate, it is unlikely that
unsecured creditors or equity holders will receive any value for their claims or
interests.
    
 
   
     The Company anticipates that the reorganization process will result in the
restructuring, cancellation and/or replacement of the interest of its existing
common and preferred stockholders. Because of the "absolute priority rule" of
Section 1129 of the Bankruptcy Code, which requires that the Company's creditors
be paid in full (or otherwise consent) before equity holders can receive any
value under a plan of reorganization, the Company previously disclosed that it
anticipated that the reorganization process would result in the elimination of
the Company's existing equity interests. Due to recent events, including
sustained improvement in the Company's operating results as well as general
improvement in the condition of the United States' economy and airline industry,
existing holders of equity interests are anticipated to receive 5 percent of the

     The pro forma fresh start reporting common equity value was estimated by
the Company with the assistance of its financial advisors. The significant
factors used in estimating this value were analyses of publicly available
information of other companies believed to be comparable to the Company,
industry, economic and overall market conditions and historical and estimated
performance of the airline industry and certain financial analyses. There may be
differences between the amounts estimated above and those actually recorded when
fresh start reporting is applied as of the Effective Date, and such differences
may be material.
    
 
   
     Under fresh start reporting, the pro forma reorganization value of the
Company has been assumed to be allocated to the reorganized Company's assets and
liabilities on a basis substantially consistent with the purchase method of
accounting. Pro forma reorganization value not attributable to specific assets
of the reorganized Company has been included as "Reorganization value in excess
of amounts allocable to identifiable assets" in the pro forma condensed balance
sheet above. The pro forma fresh start reporting adjustments relate primarily to
the adjustment of the reorganized Company's assets and liabilities to fair
market values as well as reflecting the issuance of new stock and debt and the
discharge of certain pre-petition liabilities under the Plan. The ultimate
amount of such adjustments, when actually recorded, will likely have a
significant effect on the reorganized Company's future operations.

2. PER SHARE DATA
    
 
   
     Primary earnings per share is based upon the weighted average number of
shares of common stock outstanding and dilutive common stock equivalents (stock
options and warrants). Primary earnings per share reflect net income adjusted
for interest on borrowings effectively reduced by the proceeds from the assumed
conversion of common stock equivalents.
    
 
   
     Fully diluted earnings per share is based on the average number of shares
of common stock and dilutive common stock equivalents outstanding adjusted for
conversion of outstanding convertible preferred stock and convertible
debentures. Fully diluted earnings per share reflect net income adjusted for
interest on borrowings effectively reduced by the proceeds from the assumed
conversion of common stock equivalents.
    
 
   
3. LONG-TERM DEBT
    
 
   
     On June 13, 1994, the Company filed a motion seeking authorization to amend
the terms and extend the maturity of approximately $77.6 million of the D.I.P.
financing to the earlier of December 31, 1994, or the Effective Date of the
Plan. On June 28, 1994, the Bankruptcy Court granted the extension of the D.I.P.
financing. One of the D.I.P. lenders has elected to be repaid as of June 30,
1994 (the prior maturity date), in the approximate amount of $1 million.
Accordingly, the outstanding principal amount of the extended D.I.P. financing
will be approximately $77.6 million. While there are certain fees to be paid in
the event that the D.I.P. financing is not fully repaid prior to September 30,
1994, there is an interest rate reduction to 90-day LIBOR plus 250 basis points
for the period July 1, 1994 through September 30, 1994, unless the extended
D.I.P. financing is not repaid by such date. Under the terms of the amended
D.I.P. financing, the Company is required to notify the lenders if the
unrestricted cash balance of the Company exceeds $175 million. Subsequent to
June 30, 1994, the Company notifed the D.I.P. lenders that the Company's
unrestricted cash exceeded $175 million. The amended D.I.P. financing contains a
minimum unencumbered cash balance requirement of $74 million and certain other
covenants with which the Company was in compliance at June 30, 1994.
    
 
   
4. COMMON STOCK
    
 
   
     In May 1994, the Company entered into a settlement agreement with the
Patrician Corporation for its preferred dividend claim and issued 336,277 shares
of common stock. In return, Patrician agreed not to bring litigation seeking to
compel the issuance of such shares, or, in the alternative, to either rescind
its prior

conversion of the Series B preferred stock into common stock, or assert a claim
for such dividends senior to Common equity.
    
 
   
5. EMPLOYEE STOCK PURCHASE PLANS
    
 
   
     Under the Plan of Reorganization, the remaining obligations of
approximately $17.6 million under notes issued in connection with the Employee
Stock Purchase Plan will be forgiven on the Effective Date in return for the
cancellation of the shares held as security for such obligations. Such notes
will be abandoned by the Company as provided for in the Bankruptcy Code.
    
 
   
     As of June 30, 1994, 7,486,427 shares of common stock had been sold under
the plans. No shares were sold during the second quarter of 1994. At June 30,
1994, the unamortized deferred compensation and outstanding receivable balance
relating to such plans amounted to $875,000 and $17,603,000, respectively.

     For the quarter and six months ended June 30, 1994, income tax expense is
solely attributable to income from continuing operations. The difference in
income taxes at the federal statutory rate ("expected taxes") to those reflected
in the financial statements (the "effective rate") primarily results from the
benefit of net operating loss carryforwards resulting in an effective tax rate
of 4 percent.

             NOTES TO CONDENSED FINANCIAL STATEMENTS -- (CONTINUED)
 
   
     As of June 30, 1994, to the best of the Company's knowledge, it has not
undergone a statutory "ownership change" (as defined in Section 382 of the
Internal Revenue Code) that would result in any material limitation of the
Company's ability to use its net operating loss and business tax credit
carryforwards in future tax years. Should an "ownership change" occur prior to
the Effective Date of a plan of reorganization, the Company's ability to utilize
said carryforwards would be significantly restricted. Further, the net operating
loss and business tax credit carryforwards may be limited as a result of the
Company's reorganization under the United States Bankruptcy Code.
    
 
   
     Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109 "Accounting for Income Taxes" (SFAS 109). Since
there was no cumulative effect of this change in accounting method, prior year
financial statements have not been restated.
    
 
   
8. COMMITMENTS AND CONTINGENCIES
    
 
   
     (a) Leases
    
 
   
     During 1991, the Company restructured its lease commitment for Airbus A320
aircraft with the lessors. As a result of the restructuring, the Company's
obligation to lease ten A320 aircraft was canceled and the basic rental rate for
twelve aircraft was revised to provide for the repayment to the lessor over the
then remaining lease term of certain advanced credits received by the Company
which relate to the ten canceled aircraft.
    
 
   
     In the third quarter of 1991, the Company requested a deferral of rent and
other periodic payments from its aircraft providers. The deferral was requested
in an effort to conserve cash and improve the Company's liquidity position. As a
condition of securing the $78 million D.I.P. financing, the Company was required
to obtain from most aircraft providers rent, principal and interest payment
deferrals in excess of $100 million covering the six-month period of June
through November 1991. These deferrals will generally be repaid with interest at
10.5 percent over the remaining term of the lease or secured borrowing with
repayment commencing generally in December 1991. At June 30, 1994 and December
31, 1993, the remaining unpaid deferrals are reported as follows:

     In the third quarter of 1992, the Company requested an additional deferral
of rent and other periodic payments from its aircraft providers. The deferral
was requested to assure sufficient liquidity to sustain operations while
additional debtor-in-possession financing was obtained. The 1992 deferrals are
generally scheduled to be repaid either without interest during the first
quarter of 1993 or with interest over a period of seven years. At June 30, 1994
and December 31, 1993, the remaining unpaid deferrals are reported as follows:

     As of June 30, 1994, the Company had 66 aircraft under operating leases
with remaining terms ranging from one year to 25 years. The Company has options
to purchase most of the aircraft at fair market value at the end of the lease
term. Certain of the agreements require security deposits and maintenance
reserve payments. The Company also leases certain terminal space, ground
facilities and computer and other equipment under noncancelable operating
leases.
    
 
   
     Future minimum rental payments for years ending December 31 under
noncancelable operating leases with initial terms of more that one years are as

     Rent expense (excluding landing fees) was approximately $118.3 million and
$126.1 million for the six months ended June 30, 1994 and 1993, respectively.
    
 
   
     Collectively, the operating lease agreements require security deposits with
lessors of $8.1 million and bank letters of credit of $17.7 million. The letters
of credit are collateralized by $17.6 million in restricted cash.
    
 
   
     (b) Revenue Bonds
    
 
   
     Special facility revenue bonds issued by a municipality have been used to
fund the acquisition of leasehold improvements at the airport which have been
leased by the Company. Under the operating lease agreements, which commenced in
1990, the Company is required to make rental payments sufficient to pay
principal and interest when due on the bonds. The Company ceased rental payments
in June 1991. The principal amount of such bonds outstanding at December 31,
1992 and 1991 was $40.7 million. In October 1993, the Company and the bondholder
agreed to reduce the outstanding balance of the bonds to $22.5 million and
adjust the related operating lease payments sufficient to pay principal and
interest on the reduced amount effective upon the confirmation of a plan of
reorganization. The remaining principal balance of $18.2 million will be
accorded the same treatment under the plan of reorganization as a pre-petition
unsecured claim. The Company also agreed to make adequate protection payments in
the amount of $150,000 per month from August 1993 to plan confirmation.
    
 
   
     (c) Aircraft Acquisitions
    
 
   
     At June 30, 1994, the Company had on order a total of 49 aircraft of the
types the Company currently operates, of which 29 are firm orders and 20 are
option orders. The table below details such deliveries.

             NOTES TO CONDENSED FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
     At June 30, 1994, the estimated aggregate cost for delivery positions under
existing contracts for the acquisition of B737's, B757's and A320 aircraft from
manufacturers listed in the above table is approximately $2.7 billion. The table
does not include any deliveries under put arrangements more fully discussed
below nor does it include orders for B747-400 aircraft.
    
 
   
     With respect to various contracts with Boeing, a purchase agreement to
acquire B737-300 aircraft has been affirmed in the Company's bankruptcy
proceedings. With timely notice to the manufacturer, all or some of these
deliveries may be converted to B737-400 aircraft. Existing purchase agreements
for B757-200 and B747-400 aircraft have not been affirmed nor rejected. All
Boeing purchase agreements require a 24-month reconfirmation notice for the
delivery of each aircraft. As of June 30, 1994, ten B737-300 and nine B757-200
delivery positions have expired due to the lack of reconfirmation by the
Company, leaving 14 and 11 delivery positions, respectively, as reflected above.
The failure to reconfirm such delivery positions exposes the Company to loss of
pre-delivery deposits and other claims which may be asserted in the bankruptcy
proceeding. The Company also has a pre-petition executory contract under which
the Company holds delivery positions for four B747-400 aircraft under firm order
and four B747-400 aircraft under option order. This executory contract allows
the Company, with the giving of adequate notice, to substitute B737-400 aircraft
for those delivery positions. The Company is currently renegotiating all of its
aircraft purchase agreements with Boeing.
    
 
   
     With respect to the purchase of aircraft from AVSA presented in the table
above, a single executory contract for the purchase of 24 A320 aircraft has not
been affirmed nor rejected by the Company. As part of the investment by AmWest,
the A320 purchase agreement was amended to provide the Company with greater
flexibility and reduced pricing. Under the modified terms, delivery dates of the
aircraft will fall in the years 1998 through 2000 with an option to further
defer deliveries. In addition, if new A320 aircraft are delivered as a result of
the renegotiated put agreement (see below), the Company will have the right to
cancel on a one-for-one basis, up to a maximum of eight non-consecutive aircraft
deliveries hereunder, subject to certain conditions. Negotiations are currently
continuing between AVSA and the Company to finalize the details of this
amendment.
    
 
   
     In June 1994, the Company renegotiated a put agreement for ten A320
aircraft. The new agreement reduced the number of put aircraft from ten to eight
and rescheduled the deliveries to start not earlier than June 30, 1995 and end
on June 30, 1999. Under the new agreement, new or used A320-200 aircraft,
B737-300 or B757-200 aircraft may be put to the Company but at a rate of no more
than two in 1995, and with respect to each ensuing year during the put period,
of no more than three. In addition, no more than five used aircraft may be put
to the Company and for every new A320 aircraft put to the Company, the Company
has the right to reduce the AVSA A320 purchase contract on a one-for-one basis.
During each January of the put period, the Company will negotiate the type and
delivery dates of the put aircraft for that year. The puts will require 150-day
notice and will be leased at fair market rates for terms ranging from three to
eighteen years, depending on the type and condition of the aircraft. As part of
the renegotiated agreement, certain cash payments and securities will be issued
to the put holder pursuant to the Plan of Reorganization (see Note 1).
    
 
   
     In connection with the $78 Million D.I.P. Facility, in December 1991, the
Company terminated its agreement with a D.I.P. lender to lease 24 aircraft and
replaced it with a put agreement to lease up to ten of the aircraft. In
September 1992, the put agreement was amended and the number of put aircraft was
reduced from ten to four with aircraft scheduled for delivery in 1994. In June
1994, the Company reached a settlement for the cancellation of the right to put
four aircraft to the Company for $4.5 million of which $2.5 million was paid in
June 1994 and $2.0 million will be paid on the Effective Date of the Plan of
Reorganization.
    
 
   
     (d) Concentration of Credit Risk
    
 
   
     The Company does not believe it is subject to any significant concentration
of credit risk. At June 30, 1994, approximately 82 percent of the Company's
receivables related to tickets sold to individual passengers

through the use of major credit cards or to tickets sold by other airlines and
used by passengers on America West. These receivables are short-term, generally
being settled shortly after sale or in the month following usage. Bad debt
losses, which have been minimal in the past, have been considered in
establishing allowances for doubtful accounts.

The Board of Directors and Stockholders
    
   
America West Airlines, Inc., D.I.P.:
    
 
   
We have audited the accompanying balance sheets of America West Airlines, Inc.,
D.I.P. (the "Company") as of December 31, 1993 and 1992, and the related
statements of operations, cash flows and stockholders' equity (deficiency) for
each of the years in the three-year period ended December 31, 1993. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
    
 
   
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurances about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
    
 
   
In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of America West Airlines, Inc.,
D.I.P. as of December 31, 1993 and 1992, and the results of its operations and
its cash flows for each of the years in the three-year period ended December 31,
1993 in conformity with generally accepted accounting principles.
    
 
   
The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in note 1 to the
financial statements, on June 27, 1991 the Company filed a voluntary petition
seeking to reorganize under Chapter 11 of the federal bankruptcy laws. This
event and circumstances relating to this event, including the Company's
significant losses, accumulated deficit and highly leveraged capital structure,
raise substantial doubt about its ability to continue as a going concern.
Although the Company is currently operating as debtor-in-possession under the
jurisdiction of the Bankruptcy Court, the continuation of the business as a
going concern is contingent upon, among other things, the ability to (1) file a
Plan of Reorganization which will gain approval of the creditors and
stockholders and confirmation by the Bankruptcy Court, (2) maintain compliance
with all debt covenants under the debtor-in-possession financing agreements, (3)
achieve satisfactory levels of future operating results and cash flows and (4)
obtain additional debt and equity. Also, as discussed in note 1 to the financial
statements, as part of the Company's bankruptcy proceeding there is uncertainty
as to the amount of claims that will be allowed and as to a number of disputed
claims which are materially in excess of amounts reflected in the accompanying
financial statements. The accompanying financial statements do not include any
adjustments that might result from the outcome of these uncertainties.

                         NOTES TO FINANCIAL STATEMENTS
    
   
                        DECEMBER 31, 1993, 1992 AND 1991
    
 
   
(1) REORGANIZATION UNDER CHAPTER 11, LIQUIDITY, FINANCIAL CONDITION AND
SUBSEQUENT EVENTS
    
 
   
     On June 27, 1991, America West Airlines, Inc., D.I.P. (the "Company" or
"America West") filed a voluntary petition in the United States Bankruptcy Court
for the District of Arizona (the "Bankruptcy Court") to reorganize under Chapter
11 of the United States Bankruptcy Code (the "Bankruptcy Code"). The Company is
currently operating as a debtor-in-possession ("D.I.P.") under the supervision
of the Bankruptcy Court. As a debtor-in-possession, the Company is authorized to
operate its business but may not engage in transactions outside its ordinary
course of business without the approval of the Bankruptcy Court.
    
 
   
     Subject to certain exceptions under the Bankruptcy Code, the Company's
filing for reorganization automatically enjoined the continuation of any
judicial or administrative proceedings against the Company. Any creditor actions
to obtain possession of property from the Company or to create, perfect or
enforce any lien against the property of the Company are also enjoined. As a
result, the creditors of the Company are precluded from collecting pre-petition
debts without the approval of the Bankruptcy Court.
    
 
   
     The Company had the exclusive right for 120 days after the Chapter 11
filing on June 27, 1991 to file a plan of reorganization and 60 additional days
to obtain necessary acceptances of such plan. Such periods may be extended at
the discretion of the Bankruptcy Court, but only on a showing of good cause, and
extensions have been obtained such that the Company has until June 10, 1994 to
file its plan of reorganization with the Court or obtain an additional
extension. Subject to certain exceptions set forth in the Bankruptcy Code,
acceptance of a plan of reorganization requires approval of the Bankruptcy Court
and the affirmative vote (i.e. 50% of the number and 66 2/3% of the dollar
amount) of each class of creditors and equity holders whose claims are impaired
by the plan.
    
 
   
     Certain pre-petition liabilities have been paid after obtaining the
approval of the Bankruptcy Court, including certain wages and benefits of
employees, insurance costs, obligations to foreign vendors and governmental
agencies, travel agent commissions and ticket refunds. The Company has also been
allowed to honor all tickets sold prior to the date it filed for reorganization.
In addition, the Company is authorized to pay pre-petition liabilities to
essential suppliers of fuel, food and beverages and to other vendors providing
critical goods and services. Subsequent to filing and with the approval of the
Bankruptcy Court, the Company assumed certain executory contracts of essential
suppliers.
    
 
   
     Parties to executory contracts may, under certain circumstances, file
motions with the Bankruptcy Court to require the Company to assume or reject
such contracts. Unless otherwise agreed, the assumption of a contract will
require the Company to cure all prior defaults under the related contract,
including all pre-petition liabilities unless terms can be negotiated. Unless
otherwise agreed, the rejection of a contract is deemed to constitute a breach
of the agreement as of the moment immediately preceding Chapter 11 filing,
giving the other party to the contract a right to assert a general unsecured
claim for damages arising out of the breach.
    
 
   
     February 28, 1992 was set as the last date for the filing of proof of
claims under the Bankruptcy Code and the Company's creditors have submitted
claims for liabilities not paid and for damages incurred. There may be
differences between the amounts at which any such liabilities are recorded in
the financial statements and the amount claimed by the Company's creditors.
Significant litigation may be required to resolve any such disputes.
    
 
   
     The Company has incurred and will continue to incur significant costs
associated with the reorganization. The amount of these costs, which are being
expensed as incurred, is expected to significantly affect results of operations.
    
 
   
     As a result of its filing protection under Chapter 11 of the Bankruptcy
Code, the Company is in default of substantially all of its debt agreements. All
outstanding pre-petition unsecured debt of the Company has been

presented in these financial statements within the caption Estimated Liabilities
Subject to Chapter 11 Proceedings.
    
 
   
     Additional liabilities subject to the proceedings may arise in the future
as a result of the rejection of executory contracts, including leases, and from
the determination by the Bankruptcy Court (or agreement by parties in interest)
of allowed claims for contingencies and other disputed amounts. Conversely, the
assumption of executory contracts and unexpired leases may convert liabilities
shown as subject to Chapter 11 proceedings to post-petition liabilities.
    
 
   
     Substantially all of the aircraft, engines and spare parts in the Company's
fleet are subject to lease or secured financing agreements that entitle the
Company's aircraft lessors and secured creditors to rights under Section 1110 of
the Bankruptcy Code. Pursuant to Section 1110, the Company had 60 days from the
date of its Chapter 11 filing, or until August 26, 1991, to bring its
obligations to these aircraft lessors and secured creditors current and/or reach
other mutually satisfactory negotiated arrangements. In September 1991, as a
condition to the borrowings under the initial $55 million D.I.P. facility, the
Company arranged for rent, principal and interest payment deferrals from a
majority of its aircraft providers as a condition to the assumption of the
related lease or secured borrowing by the Company. As a result of these
arrangements, the Company was able to assume the executory contracts associated
with 83 aircraft in its fleet without having to bring its obligations to these
aircraft providers current. In addition, as part of the initial D.I.P. facility,
the Company assumed and brought current lease agreements for 16 Airbus A320
aircraft, three CFM engines, a Boeing 757-200 and a Boeing 737-300. Twenty-two
aircraft were deemed surplus to the Company's needs and the associated executory
contracts were rejected. Included in 1991 reorganization costs is $35.2 million
in write-offs of leasehold improvements, security deposits, accrued maintenance,
accrued rents and other costs to return the aircraft which were subject to the
rejected aircraft agreements. In certain cases, final agreements were reached
with such aircraft providers and no further claims by such providers will be
pursued as a result of the rejections. In other instances, the aircraft
providers have filed claims in the normal course of the bankruptcy and as of
December 31, 1993 significant claims for rejected aircraft have not yet been
settled.
    
 
   
     Due to the uncertain nature of many of the potential claims, the Company is
unable to project the magnitude of such claims with any degree of certainty.
However, the claims (pre-petition claims and administrative claims) that have
been filed against the Company are in excess of $2 billion. Such aggregate
amount includes claims of all character, including, but not limited to,
unsecured claims, secured claims, claims that have been scheduled but not filed,
duplicative claims, tax claims, claims for leases that were assumed, and claims
which the Company believes to be without merit; however, claims filed for which
an amount was not stated, are not reflected in such amount. The Company is
unable to estimate the potential amount of such unstated claims; however, the
amount of such claims could be material.
    
 
   
     The Company is in the process of reviewing the general unsecured claims
asserted against the Company. In many instances, such review process will
include the commencement of Bankruptcy Court proceedings in order to determine
the amount at which such claims should be allowed. The Company has accrued its
estimate of claims that will be allowed or the minimum amount at which it
believes the asserted general unsecured claims will be allowed if there is no
better estimate within the range of possible outcomes. However, the ultimate
amount of allowed claims will be different and such differences could be
material. The Company is unable to estimate the amount of such differences with
any reasonable degree of certainty at this time.
    
 
   
     The Bankruptcy Code requires that all administrative claims be paid on the
effective date of a plan of reorganization unless the respective claimants
agreed to different treatment. Consequently, depending on the ultimate amount of
administrative claims allowed by the Bankruptcy Court, the Company may be unable
to obtain confirmation of a plan of reorganization. The Company is actively
negotiating with claimants to achieve mutually acceptable dispositions of these
claims. Since the commencement of the bankruptcy proceeding, claims alleging
administrative expense priority totaling more than $153 million have been filed
and an additional claim of $14 million has been alleged. As of February 28,
1994, $115 million of the filed claims have

been allowed and settled for $50.2 million in the aggregate. The Company is
currently negotiating the resolution of the remaining $38 million filed
administrative expense claim (which relates to a rejected lease of a Boeing
737-300 aircraft) and the alleged $14 million administrative claim (which
relates to a rejected lease of a Boeing 757-200 aircraft). Claims have been or
may be asserted against the Company for alleged administrative rent and/or
breach of return conditions (i.e. maintenance standards), guarantees and tax
indemnity agreements related to aircraft or engines abandoned or rejected during
the bankruptcy proceedings. Additional claims may be asserted against the
Company and allowed by the Bankruptcy Court. The amount of such unidentified
administrative claims may be material.
    
 
   
  Plan of Reorganization
    
 
   
     Under the Bankruptcy Code, the Company's pre-petition liabilities are
subject to settlement under a plan of reorganization. Pursuant to an extension
granted by the Bankruptcy Court on February 2, 1994, the Company has the
partially exclusive right, until June 10, 1994 (unless extended by the
Bankruptcy Court), to file a plan of reorganization. Each of the official
committees has also been approved to submit a plan of reorganization. The
exclusivity period may be extended by the Bankruptcy Court upon a showing of
cause after notice has been given and a hearing has been held, although no
assurance can be given that any additional extensions will be granted if
requested by the Company. The Company has agreed not to seek additional
extensions of the exclusivity period without the advance consent of the
Creditors' Committee and the Equity Committee.
    
 
   
     On December 8, 1993 and February 16, 1994, the Bankruptcy Court entered
certain orders which provided for a procedure pursuant to which interested
parties could submit proposals to participate in a plan of reorganization for
America West. The Bankruptcy Court also set February 24, 1994 as the date for
America West to select a "Lead Plan Proposal" from the proposals submitted.
    
 
   
     On February 24, 1994, America West selected as its Lead Plan Proposal an
investment proposal submitted by AmWest Partners, L.P., a limited partnership
("AmWest"), which includes Air Partners II, L.P., Continental Airlines, Inc.,
Mesa Airlines, Inc. and Fidelity Management Trust Company. On March 11, 1994,
the Company and AmWest entered into a revised investment agreement which
substantially incorporates the terms of the AmWest investment proposal (the
"Investment Agreement"). The Investment Agreement provides that AmWest will
purchase from America West equity securities representing a 37.5% ownership
interest in the Company for $120 million and $100 million in new senior
unsecured debt securities. The Investment Agreement also provides that, in
addition to the 37.5% ownership interest in the Company, AmWest would also
obtain 72.9% of the total voting interest in America West after the Company is
reorganized. The terms of the Investment Agreement will be incorporated into a
plan of reorganization to be filed with the Bankruptcy Court; however,
modifications to the Investment Agreement may occur prior to the submission of a
plan of reorganization and such modifications may be material. There can be no
assurance that a plan of reorganization based upon the Investment Agreement will
be accepted by the parties entitled to vote thereon or confirmed by the
Bankruptcy Court.
    
 
   
     In addition to the interest in the reorganized America West that would be
acquired by AmWest pursuant to the Investment Agreement, the Investment
Agreement also provides for the following:
    
 
   
     1. The D.I.P. financing would be repaid in full with cash on the date a
plan of reorganization is confirmed ("Reorganization Date").
    
 
   
     2. On the Reorganization Date, unsecured creditors would receive 45% of the
new common equity in the reorganized Company, with the potential to receive up
to 55% of such equity if within one year after the Reorganization Date, the
value of the securities distributed to them has not provided them with a full
recovery under the Bankruptcy Code. In addition, unsecured creditors would have
the right to elect to receive cash at

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
$8.889 per share up to an aggregate maximum amount of $100 million, through a
repurchase by AmWest of a portion of the shares to be issued to unsecured
creditors under a plan of reorganization.
    
 
   
     3. Holders of equity interests would have the right to receive up to 10% of
the new common equity of the Company, depending on certain conditions
principally involving a determination as to whether the unsecured creditors had
received a full recovery on account of their claims. In addition, holders of
equity interests would have the right to purchase up to $15 million of the new
common equity in the Company for $8.296 per share from AmWest, and would also
receive warrants entitling them to purchase, together with AmWest, up to 5% of
the reorganized Company's common stock, at a price to be set so that the
warrants would have value only after the unsecured creditors would have received
full recovery on their claims.
    
 
   
     4. In exchange for certain concessions principally arising from
cancellation of the right of Guinness Peat Aviation ("GPA") affiliates to put to
America West 10 Airbus A320 aircraft at fixed rates, GPA, or certain affiliates
thereof, would receive (i) 7.5% of the new common equity in the reorganized
Company, (ii) warrants to purchase up to 2.5% of the reorganized Company's
common stock on the same terms as the AmWest warrants, (iii) $3 million in new
senior unsecured debt securities, and (iv) the right to require the Company to
lease up to eight aircraft of types operated by the Company from GPA prior to
June 30, 1999 on terms which the Company believes to be more favorable than
those currently applicable to the put aircraft. See note 11 for an additional
discussion of the put rights.
    
 
   
     5. Continental Airlines, Inc., Mesa Airlines, Inc. and America West would
enter into certain alliance agreements which would include code-sharing,
schedule coordination and certain other relationships and agreements. A
condition to proceeding with a plan of reorganization based upon the Investment
Agreement would be that these agreements be in form and substance satisfactory
to America West, including the Company's reasonable satisfaction that such
alliance agreements when fully implemented will result in an increase in pre-tax
income of not less than $40 million per year.
    
 
   
     6. The expansion of the Company's board of directors to 15 members. Nine
members would be designated by AmWest and other members reasonably acceptable to
AmWest would include four members designated by representatives of the Company,
the Equity Committee and the Creditors' Committee and two members designated by
GPA.
    
 
   
     7. The Investment Agreement also provides for many other matters, including
the disposition of the various types of claims asserted against the Company, the
adherence to the Company's aircraft lease agreements, the amendment of the
Company's aircraft purchase agreements and release of the Company's employees
from all currently existing obligations arising under the Company's stock
purchase plan in consideration for the cancellation of the shares of Company
stock securing such obligations.
    
 
   
     The Company has also entered into a revised Interim Procedures Agreement
(the "Procedures Agreement") with AmWest. The Procedures Agreement is subject to
the approval of the Bankruptcy Court and sets forth terms and conditions upon
which the Company must operate prior to the effective date of a confirmed plan
of reorganization based upon the terms of the Investment Agreement. The
Procedures Agreement provides for the reimbursement of AmWest's expenses (up to
a maximum of $3.6 million) as well as a termination fee of up to $8 million
under certain conditions. The Procedures Agreement has not yet been approved by
the Bankruptcy Court.
    
 
   
     The Company is currently developing with AmWest a plan of reorganization
based upon the foregoing terms. The Equity Committee has agreed to support the
plan. The Creditors' Committee has indicated that it does not support the
current terms of the Investment Agreement. Another group interested in
developing a plan of reorganization with the Company has proposed to invest $155
million in equity securities and $65 million in new senior unsecured debt
securities. The proponent of this proposal would receive a 33.5% ownership
interest in the reorganized Company, current equity holders would receive a 4%
ownership interest

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
in the reorganized company and the unsecured creditors would receive a 62.5%
ownership interest in the reorganized company.
    
 
   
     Any plan of reorganization must be approved by the Bankruptcy Court and by
specified majorities of each class of creditors and equity holders whose claims
are impaired by the plan. Alternatively, absent the requisite approvals, the
Company may seek Bankruptcy Court approval of its reorganization plan under
Section 1129(b) of the Bankruptcy Code, assuming certain tests are met. The
Company cannot predict whether any plan submitted by it will be approved.
    
 
   
     The Company is currently unable to predict when it may file a plan of
reorganization based upon the Investment Agreement, but intends to do so as soon
as practicable. Once a plan with a disclosure statement is filed by any party,
the Bankruptcy Court will hold a hearing to determine the adequacy of the
information contained in such disclosure statement. Only upon receiving an order
form the Bankruptcy Court providing that the disclosure statement accompanying
any such plan contains adequate information as required by Section 1125 of the
Bankruptcy Code, may a party solicit acceptances or rejections of any such plan
of reorganization. Following entry of an order approving the disclosure
statement, the plan will be sent to creditors and equity holders for voting
pursuant to both the Bankruptcy Code and orders that will be entered by the
Bankruptcy Court. Following submission of the plan to holders of claims and
equity interest, the Bankruptcy Court will hold a hearing to consider
confirmation of the plan pursuant to Section 1129 of the Bankruptcy Code.
Although the Bankruptcy Code provides for certain minimum time periods for these
events, the Company is unable to reasonably estimate when a plan based on the
Investment Agreement might be submitted for voting and confirmation.
    
 
   
     If at any time the Creditors' Committee, the Equity Committee or any
creditor of the Company or equity holder of the Company believes that the
Company is or will not be in a position to sustain operations, such party can
move in the Bankruptcy Court to compel a liquidation of the Company's estate by
conversion to Chapter 7 bankruptcy proceedings or otherwise. In the event that
the Company is forced to sell its assets and liquidate, it is unlikely that
unsecured creditors or equity holders will receive any value for their claims or
interests.
    
 
   
     The Company anticipates that the reorganization process will result in the
restructuring, cancellation and/or replacement of the interest of its existing
common and preferred stockholders. Because of the "absolute priority rule" of
Section 1129 of the Bankruptcy Code, which requires that the Company's creditors
be paid in full (or otherwise consent) before equity holders can receive any
value under a plan of reorganization, the Company previously disclosed that it
anticipated that the reorganization process would result in the elimination of
the Company's existing equity interests. Due to recent events, including
sustained improvement in the Company's operating results as well as general
improvement in the condition of the United States' economy and airline industry,
some form of distribution to the equity interests pursuant to Section 1129 may
occur. However, there can be no assurances in this regard.
    
 
   
     The accompanying financial statements have been prepared on a going concern
basis which assumes continuity of operations and realization of assets and
liquidation of liabilities in the ordinary course of business. As a result of
the reorganization proceedings, there are significant uncertainties relating to
the ability of the Company to continue as a going concern. The financial
statements do not include any adjustments that might be necessary as a result of
the outcome of the uncertainties discussed herein including the effects of any
plan of reorganization.
    
 
   
(2) ESTIMATED LIABILITIES SUBJECT TO CHAPTER 11 PROCEEDINGS AND REORGANIZATION
EXPENSE
    
 
   
     Under Chapter 11, certain claims against the Company in existence prior to
the filing of the petitions for relief under the Code are stayed while the
Company continues business operations as debtor-in-possession.

These pre-petition liabilities are expected to be settled as part of the plan of
reorganization and are classified as "Estimated liabilities subject to Chapter
11 proceedings."
    
 
   
     Estimated liabilities subject to Chapter 11 proceedings as of December 31,
1993 and 1992 consisted of the following:

(3) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    
 
   
  (a) Financial Reporting for Bankruptcy Proceedings
    
 
   
     On November 19, 1990, the American Institute of Certified Public
Accountants issued Statement of Position 90-7, "Financial Reporting by Entities
in Reorganization Under the Bankruptcy Code" ("SOP 90-7"). SOP 90-7 provides
guidance for financial reporting by entities that have filed petitions with the
Bankruptcy Court and expect to reorganize under Chapter 11 of the Code.
    
 
   
     SOP 90-7 recommends that all such entities report consistently while
reorganizing under Chapter 11, with the objective of reflecting their financial
evolution. To achieve such objectives, their financial statements should
distinguish transactions and events that are directly associated with the
reorganization from those of the operations of the ongoing business as it
evolves.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
     SOP 90-7 became effective for financial statements of enterprises that
filed petitions under the Code after December 31, 1990, although earlier
application was encouraged. The Company has implemented the guidance provided by
SOP 90-7 in the accompanying financial statements.
    
 
   
     Pursuant to SOP 90-7, pre-petition liabilities are reported on the basis of
the expected amounts of such allowed claims, as opposed to the amounts for which
those allowed claims may be settled. Under an approved final plan of
reorganization, those claims may be settled at amounts substantially less than
their allowed amounts.

     Cash equivalents consist of all highly liquid debt instruments purchased
with original maturities of three months or less and are carried at cost which
approximates market.
    
 
   
  (c) Restricted Cash
    
 
   
     Restricted cash includes cash held in Company accounts, but pledged to an
institution which processes credit card sales transactions and cash deposits
securing certain letters of credit.
    
 
   
  (d) Expendable Spare Parts and Supplies
    
 
   
     Flight equipment expendable spare parts and supplies are valued at average
cost. Allowances for obsolescence are provided, over the estimated useful life
of the related aircraft and engines, for spare parts expected to be on hand at
the date the aircraft are retired from service.
    
 
   
  (e) Property and Equipment
    
 
   
     Property and equipment is stated at cost or, if acquired under capital
leases, at the lower of the present value of minimum lease payments or fair
market value at the inception of the lease. Interest capitalized on advance
payments for aircraft acquisitions and on expenditures for aircraft improvements
is part of the cost. Property and equipment is depreciated and amortized to
residual values over the estimated useful lives or the lease term using the
straight-line method. The Company discontinued capitalizing interest on June 27,
1991 due to the Chapter 11 filing.
    
 
   
     The estimated useful lives for the Company's property and equipment range
from three to twelve years for owned property and equipment and to thirty years
for the reservation and training center and technical support facilities. The
estimated useful lives of the Company's owned aircraft, jet engines, flight
equipment and rotable parts range from eleven to twenty-two years. Leasehold
improvements relating to flight equipment and other property on operating leases
are amortized over the life of the lease or the life of the asset, whichever is
shorter.
    
 
   
     Routine maintenance and repairs are charged to expense as incurred. The
cost of major scheduled airframe, engine and certain component overhauls are
capitalized and amortized over the periods benefited and included in
depreciation and amortization expense. Additionally, a provision for the
estimated cost of scheduled airframe and engine overhauls required to be
performed on leased aircraft prior to their return to the lessors has been
provided.
    
 
   
  (f) Revenue Recognition
    
 
   
     Passenger revenue is recognized when the transportation is provided. Ticket
sales for transportation which has not yet been provided are reflected in the
financial statements as air traffic liability.

  (g) Passenger Traffic Commissions and Related Fees
    
 
   
     Passenger traffic commissions and related fees are expensed when the
transportation is provided and the related revenue is recognized. Passenger
traffic commissions and related fees not yet recognized are included as a
prepaid expense.
    
 
   
  (h) Income Taxes
    
 
   
     Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109, Accounting for Income Taxes.
    
 
   
     As more fully discussed at note 5, adoption of the new standard changes the
Company's method of accounting for income taxes from the deferred approach to an
asset and liability approach.
    
 
   
     As with the prior standard, the Company continues to account for its
investment tax credits and general business credits by use of the flow-through
method.
    
 
   
  (i) Per Share Data
    
 
   
     Primary earnings (loss) per share is based upon the weighted average number
of shares of common stock outstanding and dilutive common stock equivalents
(stock options and warrants). Primary earnings per share reflect net income
adjusted for interest on borrowings effectively reduced by the proceeds from the
assumed conversion of common stock equivalents.
    
 
   
     Fully diluted earnings per share in 1993 is based on the average number of
shares of common stock and dilutive common stock equivalents outstanding
adjusted for conversion of outstanding convertible preferred stock and
convertible debentures. Fully diluted earnings per share reflects net income
adjusted for interest on borrowings effectively reduced by the proceeds from the
assumed conversion of common stock equivalents.
    
 
   
  (j) Frequent Flyer Awards
    
 
   
     The Company maintains a frequent travel award program known as "FlightFund"
that provides a variety of awards to program members based on accumulated
mileage. The estimated cost of providing the free travel, using the incremental
cost method as adjusted for estimated redemption rates, is recognized as a
liability and charged to operations as program members accumulate mileage.
    
 
   
  (k) Manufacturers' and Deferred Credits
    
 
   
     In connection with the acquisition of certain aircraft and engines, the
Company receives various credits. Such manufacturers' credits are deferred until
the aircraft and engines are delivered, at which time they are either applied as
a reduction of the cost of acquiring owned aircraft and engines, resulting in a
reduction of future depreciation expense, or amortized as a reduction of rent
expense for leased aircraft and engines.
    
 
   
  (l) Fair Value of Financial Instruments
    
 
   
     The fair value estimates and assumptions used in developing the estimates
of the Company's financial instruments are as follows:
    
 
   
     Cash and Cash Equivalents
    
 
   
     The carrying amount approximates fair value because of the short maturity
of those instruments.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
     Accounts Receivable and Accounts Payable
    
 
   
     The carrying amount of accounts receivable and accounts payable
approximates fair value as they are expected to be collected or paid within 90
days of year-end.
    
 
   
     Long-term Debt and Estimated Liabilities Subject to Chapter 11 Proceedings
    
 
   
     The fair value of long-term debt and estimated liabilities subject to
Chapter 11 proceedings cannot readily be estimated as quoted market prices are
not available. Additionally, future cash flows cannot be estimated as the
repayment of these instruments is subject to disposition within the bankruptcy
proceedings.
    
 
   
  (m) Reclassifications
    
 
   
     Certain prior year reclassifications have been made to conform to the
current year presentation.
    
 
   
(4) LONG-TERM DEBT
    
 
   
     Long-term debt consists of the following:

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
     As part of the Chapter 11 reorganization process, the Company is required
to notify all known or potential claimants for the purpose of identifying all
pre-petition claims against the Company. Additional bankruptcy claims and
pre-petition liabilities may arise by termination of various contractual
obligations and as certain contingent and/or potentially disputed bankruptcy
claims are allowed for amounts which may differ from those shown on the balance
sheet.
    
 
   
     As discussed in note 1, payment of these liabilities, including maturity of
debt obligations, is stayed while the debtor continues to operate as a
debtor-in-possession. As a result, contractual terms have been suspended with
respect to debt subject to the Chapter 11 proceedings. The following paragraphs
include discussion of the original contractual terms of the long-term debt;
however, the maturity and terms of the long-term debt subsequent to the petition
date may differ as a result of negotiations that take place as part of the plan
of reorganization.
    
 
   
     No principal or interest may be paid on pre-petition debt without the
approval of the Bankruptcy Court. The Company has continued to accrue and pay
interest on its long-term debt related to D.I.P. financing, affirmed long-term
debt and secured debt included in estimated liabilities subject to Chapter 11
proceedings only to the extent that, in the Company's opinion, the value of
underlying collateral exceeds the principal amount of the secured claim. The
Company believes it is probable such interest will be an allowed secured claim
as part of the bankruptcy proceeding. Except as otherwise stated above, the
Company ceased accruing interest on pre-petition debt as of June 27, 1991, due
to uncertainties relating to a final plan of reorganization.
    
 
   
     (a) In September 1991, the Company completed arrangements for a $55 million
D.I.P. credit facility. The D.I.P. credit facility is secured by a first
priority lien senior to all other liens on substantially all existing assets of
the Company, except that such lien is junior in priority to Permitted First
Liens (as such term is defined in the D.I.P. credit facility documents) with
respect to the property encumbered thereby. In December 1991, the Company
completed arrangements for an additional $23 million of D.I.P. financing under
terms and conditions substantially the same as those associated with the $55
million D.I.P. credit facility. Quarterly interest payments for the D.I.P.
financings commenced in the quarter ending December 31, 1991 at the 90-day
London Interbank Offered Rate (LIBOR) plus 3.5% and quarterly principal
repayments of $3.9 million were to commence in September 1992 with the balance
due in September 1993, or earlier upon confirmation of an approved plan of
reorganization.
    
 
   
     In connection with the $23 million of D.I.P. financing, the Company agreed
to convert advanced cash credits for 24 Airbus A320 aircraft previously provided
to the Company into an unsecured priority term loan. At December 31, 1993, the
amount of the term loan was $68.4 million including accrued interest of $21.9
million. Until the Reorganization Date, the term loan will accrue interest at
12% per annum and such interest will be added to the principal balance. On the
Reorganization Date, 85% of the outstanding balance will be converted into an
eight-year term loan which will accrue interest at 2% over 90-day LIBOR and will
be secured by substantially all the assets of the Company if the D.I.P.
financing is fully repaid. Principal payments will be made in equal quarterly
installments, plus interest, commencing after the Reorganization Date. The
Company has the right to prepay the loan if the D.I.P. financing is fully
repaid. The remaining 15% of the term loan will be treated as a general
unsecured claim without priority status under the Company's plan of
reorganization. In the first quarter of 1994, the Company received information
that the term loan was purchased by a third party.
    
 
   
     In connection with the D.I.P. financing, a D.I.P. lender agreed to acquire
the Company's Honolulu to Nagoya, Japan route for $15 million. The Nagoya route
sale was finalized in March 1992, resulting in a gain of $15 million, which is
included in other non-operating income in the accompanying statement of
operations. Upon the completion of the sale of the Nagoya route, $10 million of
the proceeds from the sale were paid to the lender to reduce the Company's
obligation to the lender under the D.I.P. financing. The balance of the proceeds
from the sale of the Nagoya route were added to the Company's working capital.
The remaining D.I.P. balance was paid to this lender in connection with the
September 1992 D.I.P. Facility.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
     In September 1992, the Company completed arrangements to expand its
existing D.I.P. financing by an additional $53 million (the "September 1992
D.I.P. Facility").
    
 
   
     As a condition to the closing of the September 1992 D.I.P. Facility, the
Company was required to reduce its aircraft fleet and the number of aircraft
types from five to three pursuant to certain agreements with third parties,
including the following:
    
 
   
     1. With the exception of four lessors (two of which participated in the
September 1992 D.I.P. Facility and did not defer or reduce their lease
payments), aircraft lessors whose aircraft were retained in the fleet and who
agreed to payment deferrals during July and August 1992, were required to waive
any default which occurred as a result of such non-payments and to defer these
payments without interest until the first calendar quarter of 1993. In addition,
effective August 1, 1992, the rental rates on these retained aircraft were
reduced to fair market lease rates for a two-year period. The rental rates
adjust to market rates effective August 1, 1994.
    
 
   
     Of the remaining two lessors, one accepted rental payment reductions and
the other agreed to a deferral of the rents from July through October 1992.
Repayment of this deferral is monthly over seven years beginning November 1992
at level principal and interest at 90-day LIBOR plus 3.5%.
    
 
   
     2. The aircraft lessors who accepted rent reductions and agreed to waive
any administrative claims arising from the reductions stipulated that, if prior
to July 31, 1994, the Company defaults on any of these leases and the aircraft
are repossessed, the lessors are entitled to fixed damages which will be
afforded priority as administrative claims. Lessors of 11 aircraft have the
option, beginning August 1, 1994, to reset the rents to the current fair market
rental rates and, if elected by the lessor, to readjust at two other two-year
intervals during the remaining term of the lease.
    
 
   
     The Company also agreed in certain cases that lessors could call the
aircraft upon 180 days notice if the lessor had a better lease proposal from
another party which the Company was unwilling to match. During the period August
1, 1994 through July 31, 1995, certain of these lessors may call their aircraft
without first giving the Company the right to match any competing offer. Call
rights with a right of first refusal affect 16 aircraft and call rights without
a right of first refusal affect 10 aircraft. In addition, in order to induce
several lessors to extend the lease terms of their aircraft, the Company agreed
that the aircraft could be called by the lessors at the end of the original
lease term. One lessor of 11 aircraft has the right to terminate each lease at
the end of the original lease term of each aircraft. Such lessor also has the
right to call its aircraft on 90 days notice at any time prior to the end of the
amended lease term. America West has no right of first refusal with respect to
such aircraft. To date, no lessor has exercised its call rights.
    
 
   
     3. Certain principal and interest payments relating to owned aircraft due
in July 1992 were deferred without interest and were repaid by March 31, 1993.
Additionally, certain other principal and interest payments due from August 1992
through January 1993 were deferred and repaid beginning February 1993 over five
to nine years with interest at approximately 10.25%. In lieu of payment
deferrals, two of the aircraft lenders agreed to adjust the interest rates based
on 90-day LIBOR plus 3.5% per annum.
    
 
   
     In September 1993, the Bankruptcy Court approved an amendment to the D.I.P.
loan agreement extending the maturity date of the loan from September 30, 1993
to June 30, 1994. Concurrent with the extension of the maturity date, $8.3
million of the principal balance was repaid to one of the participants who did
not agree with the amendment. Interest on all funds advanced under the D.I.P.
facility accrues at 3.5% per annum, over 90-day LIBOR and is payable quarterly.
The amended D.I.P. loan agreement defers all principal payments to the earlier
of June 30, 1994 or the effective date of a confirmed Chapter 11 plan of
reorganization with the exception of $5 million that will be due on March 31,
1994. The amended terms of the D.I.P. financing require the Company to notify
the D.I.P. lenders if the unrestricted cash balance of the Company exceeds $125
million. Upon receipt of such notice, the D.I.P. lenders may require the Company
to prepay the D.I.P. financing by the amount of such excess. Subsequent to
December 31, 1993, the Company notified the

D.I.P. lenders that the Company's unrestricted cash exceeded $125 million;
however, the D.I.P. lenders have not exercised their prepayment rights. The
D.I.P. financings contain a minimum unencumbered cash balance requirement of $55
million at December 31, 1993 and other financial covenants. At December 31,
1993, the Company was in compliance with these covenants.
    
 
   
     As a condition to extending the maturity date of the D.I.P. financing in
September 1993, the Company also agreed to pay a facility fee of $627,000 to the
D.I.P. lenders on September 30, 1993 and to pay an additional facility fee equal
to 1/4% of the then outstanding balance of the D.I.P. financing on March 31,
1994. Consequently, the outstanding balance of $83.6 million is classified as a
current liability as of December 31, 1993. Presently, the Company does not
possess sufficient liquidity to satisfy the D.I.P. financing nor does it appear
likely that new equity capital will be obtained and a plan of reorganization
confirmed prior to June 30, 1994. Consequently, the Company will be required to
obtain alternative repayment terms from the D.I.P. lenders. There can be no
assurance that alternative repayment terms will be obtained. The Company
believes that any extension of the D.I.P. financing will be for a short period
of time and would be concurrent with the implementation of a plan of
reorganization.
    
 
   
     The D.I.P. financings contain a minimum unencumbered cash balance
requirement of $55 million at December 31, 1993 and other financial covenants.
At December 31, 1993, the Company was in compliance with these covenants.
    
 
   
     (b) These notes from financial institutions, secured by seventeen aircraft
with a net book value of $327.6 million, are payable in semi-monthly, monthly,
quarterly and semi-annual installments ranging from $75,000 to $1,637,000 plus
interest at 30-day LIBOR plus 3.5% (6.88% at December 31, 1993) to 10.79%, with
maturities ranging from 1999 to 2008. Approximately $105.3 million of these
secured notes have provisions providing for the reset of interest rates at
various future dates based on fluctuations in indices such as the Eurodollar
rate. Additionally, interest rates and principal payments for certain of these
notes were modified, as discussed above, in connection with the September 1992
D.I.P. Facility.
    
 
   
     (c) The Company has a $40 million line of credit that extends to December
31, 1997 for which no borrowing can occur after December 31, 1994. The purpose
of the line is to provide for the initial provisioning of spare parts for Airbus
A320 aircraft. The loan is repaid quarterly with level principal payments of
$970,000 each and interest at LIBOR plus 4%. At December 31, 1993 and 1992, the
Company had borrowings outstanding of $15.5 million and $20.4 million,
respectively, under this credit facility. However, the lender will not make the
unused credit of $24.5 million available at December 31, 1993 as a result of the
Chapter 11 filing. This loan was affirmed in December 1991 by the Bankruptcy
Court under Section 1110 of the Bankruptcy Code.
    
 
   
     The Company also has a $25 million line of credit that extends to September
1997 under which no borrowing could occur after September 1992. The credit line
was used for spare engine parts and has an interest rate of LIBOR plus 4%. At
December 31, 1993 and 1992, the Company had borrowings outstanding of $3.1
million and $4.6 million, respectively, under this credit facility. In
connection with the financing by this same lender of two aircraft flight
simulators in October 1992 (see (e)), this loan was affirmed in the bankruptcy
proceeding. Consequently, the outstanding balance at December 31, 1993 is
included in long-term debt.
    
 
   
     (d) This note from an aircraft engine manufacturer was originally made for
$30 million in September 1990. The note is secured by two aircraft, spare engine
parts and other equipment. Interest on the note began to accrue at its inception
at 90-day LIBOR plus 2.0%, compounded quarterly, until September 1993 when all
such accrued interest, or approximately $6 million, was paid. Interest is
currently paid quarterly at the same interest rate. In October 1992, this lender
financed two new flight simulators which were securing this note (see (e)), and
this loan was reduced by the amount of such financing, or approximately $22.8
million. Repayment of the balance of this loan is dependent on the future
delivery of certain firm ordered aircraft

scheduled to begin in November 1996 (however, the related aircraft purchase
agreement has been neither affirmed nor rejected at December 31, 1993). In
connection with the above financing of the two flight simulators, this note was
affirmed in the bankruptcy proceedings, and the outstanding balances at December
31, 1993 and 1992 are included in long-term debt.
    
 
   
     (e) In October 1992, the Company acquired two flight simulators and
executed two notes secured by the simulators. The notes are payable in 84 equal
monthly principal installments, plus accrued interest at LIBOR plus 2%. However,
the Company has the right, upon the giving of notice to the lender, to fix the
interest rate at the greater of the then current LIBOR plus 2% or 6.375%. In
connection with this financing, the Company affirmed in the bankruptcy
proceedings the agreements for a certain note payable (see (d) above) and a line
of credit (see (c) above).
    
 
   
     (f) In 1993, the Company settled three administrative claims with three
four-year promissory notes totaling $9.6 million with quarterly principal
payments and interest at 6%. At December 31, 1993, the outstanding balance of
these promissory notes was $8.7 million.
    
 
   
     Also in 1993, the Company renegotiated a note for certain ground equipment
for $2 million as part of an administrative claim settlement which takes effect
upon the confirmation of a plan of reorganization. The Company is required to
make adequate protection payments of $8,000 per month from the settlement date
until plan confirmation, at which time, the note term is 5 years with interest
at 6%.
    
 
   
     (g) The Company's 7 3/4% convertible subordinated debentures are
convertible into common stock at $13.50 per share. The debentures are redeemable
at prices ranging from 101.55% of the principal amount at December 31, 1993 to
100% of the principal amount in 1995 and thereafter. Annual sinking fund
payments of $1.5 million are required beginning in 1995.
    
 
   
     (h) The Company's 7 1/2% convertible subordinated debentures are
convertible into common stock at $14.00 per share. The debentures are redeemable
at prices ranging from 102.25% of the principal amount at December 31, 1993 to
100% of the principal amount in 1996 and thereafter. Annual sinking fund
payments of $1.6 million are required beginning in 1996.
    
 
   
     (i) The Company's 11 1/2% convertible subordinated debentures are
convertible into common stock at $10.50 per share. The debentures are redeemable
at prices ranging from 105.75% of the principal amount from January 1, 1994 to
100% of the principal amount in 1999 and thereafter. Annual sinking fund
payments of $5.8 million are required beginning in 1999.
    
 
   
     During 1991, certain bondholders converted $22.1 million of the 11 1/2%
convertible subordinated debentures into common stock. The conversion of the
11 1/2% subordinated debentures resulted in a charge to other non-operating
expense of $875,000 for incremental shares issued upon conversion. Certain
bondholders converted $1.4 million of the 7 1/2% convertible subordinated
debentures and $4.4 million of the 7 3/4% convertible subordinated debentures
into common stock.
    
 
   
     During 1992, certain bondholders converted $95,000 of the 7 1/2%
convertible subordinated debentures, $100,000 of the 7 3/4% convertible
subordinated debentures and $3.5 million of the 11 1/2% convertible subordinated
debentures into common stock.
    
 
   
     During 1993, certain bondholders converted $360,000 of the 7 1/2%
convertible subordinated debentures, $275,000 of the 7 3/4% convertible
subordinated debentures and $1.3 million of the 11 1/2% convertible subordinated
debentures into common stock.
    
 
   
     All of the convertible subordinated debenture interests will be subject to
settlement of their stated amounts in a plan of reorganization, thereby
eliminating the need for continued deferral of the debt issuance costs.
Therefore, the unamortized debt issuance costs of $2.8 million for these
convertible subordinated

debentures were charged to operations as reorganization expense in 1991. The
Company ceased accruing interest on all of these debentures as of June 27, 1991
in accordance with SOP 90-7.
    
 
   
     (j) This note from an aircraft manufacturer for deferred pre-delivery
payments was required under a purchase agreement entered into in 1990. The
deferred pre-delivery payments will accrue interest at one year LIBOR plus 4%
with both principal and interest due upon delivery of the aircraft. The Company
has ceased accruing interest on the outstanding balance in accordance with SOP
90-7. The acquisition of the aircraft associated with these deferred
pre-delivery payments is subject to the affirmation or rejection of the
respective aircraft purchase agreement by the Company in the reorganization
proceeding.
    
 
   
     (k) The Company has a $20 million secured revolving credit facility with a
group of financial institutions that expired on April 17, 1993. Borrowings under
this credit facility were either made i) at the federal funds rate plus 1%, ii)
based on a CD rate or iii) 90-day LIBOR two business days prior to the first day
of the interest period. The borrowings are secured by certain assets. The
Company is obligated to pay a commitment fee equal to  1/4% per annum on the
average daily amount by which the aggregate commitments exceed the applicable
borrowing base and  1/2% per annum on the average daily amount by which the
lower of the aggregate commitments or applicable borrowing base exceeds the
aggregate principal amount on all outstanding loans. At December 31, 1993 and
1992, the Company had an outstanding balance of $9.9 million and $11 million,
respectively, under the revolving credit agreement. Proceeds from sales of
assets securing the loan were used to prepay the loan during 1993. The Company
ceased accruing interest on the outstanding balance as of June 27, 1991 in
accordance with SOP 90-7.
    
 
   
     (l) The holders of industrial development revenue bonds have the right to
put the bonds back to the Company at various times. If such a put occurs, the
Company has an agreement with the underwriters to remarket the bonds. Any bonds
not remarketed will be retired utilizing a letter of credit. Any funding under
the letter of credit will be in the form of a two-year term loan at prime plus
2%. During the first quarter of 1991, the Company redeemed $14.5 million of the
$44 million of industrial development revenue bonds issued and outstanding and
agreed to a seven-year amortization schedule for the redemption of the remaining
balance. In July and August 1991, $29.5 million in the aggregate was drawn
against the letter of credit facility that supported these bonds. The Company
intends to remarket the bonds in the future. Such draws were made on behalf of
holders of such bonds who exercised their right to put the bonds back to the
Company for purchase. The bonds are currently held in trust for the benefit of
the Company. These bonds were issued in connection with the Company's technical
support facility.
    
 
   
     (m) These draws on a letter of credit from a financial institution, secured
by spare rotable parts with a net book value of $35.8 million, are payable in
quarterly installments of $1.3 million plus interest at prime plus 4.5%. The
Company has ceased accruing interest as of June 27, 1991 on the outstanding
balance in accordance with SOP 90-7.
    
 
   
     Maturities of long-term debt, excluding $225 million included in estimated
liabilities subject to Chapter 11 proceedings, for the years ending December 31
are as follows:

(5) INCOME TAXES
    
 
   
  Adoption of New Accounting Standard
    
 
   
     As of January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109). SFAS 109
is a fundamental change in the manner used to account for income taxes in that
the deferred method has been replaced with an asset and liability approach.
Under SFAS 109, deferred tax assets (subject to a possible valuation allowance)
and liabilities are recognized for the expected future tax consequences of
events that are reflected in the Company's financial statements or tax returns.
    
 
   
     In the year of adoption, SFAS 109 permits an enterprise to record in its
current year financial statements, the cumulative effect (if any) of the change
in accounting principle. Upon adoption, the Company did not need to record a
cumulative effect adjustment.
    
 
   
  Income Tax Expense
    
 
   
     For the year ended December 31, 1993, the Company recorded income tax
expense as follows:

                                                                        ====

                                                                        ====
</TABLE>
    
 
   
     For the year ended December 31, 1993, income tax expense is solely
attributable to income from continuing operations. The difference in income
taxes at the federal statutory rate ("expected taxes") to those reflected in the
financial statements (the "effective rate") results from the effect of the
benefit of net operating loss carryforwards of $12.6 million and state income
tax expense, net of federal tax benefit of $55,000, for an effective tax rate of
2%. In 1992 and 1991, the tax benefits at the federal statutory rate of 34% were
offset by the generation of net operating loss carryforwards.
    
 
   
     At December 31, 1993, the Company has available net operating loss,
business tax credit and alternative minimum tax credit carryforwards for federal
income tax purposes of $530.3 million, $12.7 million and $700,000, respectively.
The net operating loss carryforwards expire during the years 1999 through 2007
while the business credit carryforwards expire during the years 1997 through
2006. However, such carryforwards are not fully available to offset federal
(and, in certain circumstances, state) alternative minimum taxable income.
Accordingly, income tax expense recognized for the year ended December 31, 1993,
is attributable to the Company's expected net current liability for federal and
various state alternative minimum taxes. The alternative minimum tax credit
carryforward does not expire and is available to reduce future income tax
payable.
    
 
   
     As of December 31, 1993, to the best of the Company's knowledge, it has not
undergone a statutory "ownership change" (as defined in sec.382 of the Internal
Revenue Code) that would result in any material limitation of the Company's
ability to use its net operating loss and business tax credit carryforwards in
future tax years. Should an "ownership change" occur prior to confirmation of a
plan of reorganization, the Company's ability to utilize said carryforwards
would be significantly restricted. Further, the net operating loss and business
tax credit carryforwards may be limited as a result of the Company's
reorganization under the United States Bankruptcy Code.

  Composition of Deferred Tax Items
    
 
   
     The Company has not recognized any net deferred tax items for the year
ended December 31, 1993. Deferred income taxes reflect the net tax effects of
temporary differences between the carrying amounts of assets and liabilities for
financial reporting purposes and the amounts used for income tax purposes.
Significant components of the Company's deferred tax assets and liabilities as
of December 31, 1993 are a result of the temporary differences related to the
items described as follows:

</TABLE>
    
 
   
     SFAS 109 requires a "more likely than not" criterion be applied when
evaluating the realizability of a deferred tax asset. Given the Company's
history of losses for income tax purposes, the volatility of the industry within
which the Company operates and certain other factors, the Company has
established a valuation allowance for the portion of its net operating loss
carryforwards that may not be available due to expirations after considering the
net reversals of future taxable and deductible differences occurring in the same
periods. In this context, the Company has taken into account prudent and
feasible tax planning strategies. After application of the valuation allowance,
the Company's net deferred tax assets and liabilities are zero.
    
 
   
(6) EMPLOYEE STOCK PURCHASE PLANS AND OTHER EMPLOYEE BENEFIT PROGRAMS
    
 
   
     The Company has a stock purchase plan covering its directors, officers and
employees and certain other persons providing service to the Company, as well as
a separate plan covering its California resident employees. At December 31,
1993, the number of shares authorized under the plans is 10,450,000. Each
participating employee is required to purchase a number of shares having an
aggregate purchase price equivalent to 20% of such employee's annual base wage
or salary on the date of purchase. Each participating employee has the option of
simultaneously purchasing additional shares having an aggregate purchase price
not exceeding 20% of such wage or salary. California resident employees electing
to participate in the plan may purchase a number of shares having an aggregate
purchase price not exceeding 40% of their annual base wage or salary on the date
of purchase at a specified price.
    
 
   
     Participating employees can elect to finance their purchase through the
Company for up to 20% of their annual base wage or salary over a five-year
period at an interest rate of 9.5%. Employee notes receivable of $17.6 million
existed at December 31, 1993 and were classified in the stockholders' deficiency
section. Shares issued under the plans cannot be sold, transferred, assigned,
pledged or encumbered in any way for a period of two years from the date such
shares are paid for and delivered to participating employees. The employees'

purchase price is 85% of the market price on the date of purchase. The
difference between the employees' purchase price and the market price is
recorded as deferred compensation and is amortized over five years.
    
 
   
     The plans provide for the purchase of additional shares of common stock up
to 10% of the employee's annual base wage during the first year of employment
and 20% of the employee's annual base wage during each subsequent calendar year.
Such purchases may be financed through the Company at the same terms as
indicated above, as long as total outstanding amounts previously financed do not
exceed 10% of the employee's annual base compensation.
    
 
   
     Effective August 1, 1991, the Company suspended the mandatory portion of
the Employee Stock Purchase Plan for 60 days. Subsequent to the expiration of
the 60-day period, the Company indefinitely suspended the Employee Stock
Purchase Plan. The Company also suspended payroll deductions related to the
Employee Stock Purchase Plan as a result of a 10% across the board reduction in
wages which commenced August 1, 1991 for all employees whose wages had not been
previously reduced. The unpaid employee stock purchase notes continue to accrue
interest. The Company anticipates that the reorganization process will result in
the restructuring, cancellation and/or replacement of the interests of its
existing common and preferred stockholders.
    
 
   
     The bankruptcy process has caused the suspension of the Company's profit
sharing plan which covers all personnel. The plan provided for the distribution
of 15% of annual pre-tax profits to employees based on each individual's base
wage. The Company made no distributions under the plan in 1993, 1992 or 1991.
    
 
   
     The Company implemented a 401(k) defined contribution plan on January 1,
1989, covering essentially all employees of the Company. Participants may
contribute from 1% to 10% of their pre-tax earnings to a maximum of $8,994. The
Company will match 25% of a participant's contributions up to 6% of the
participant's annual pre-tax earnings. The Company's contribution expense to the
plan totaled $2.1 million, $2 million and $4.9 million in 1993, 1992 and 1991,
respectively.
    
 
   
     The Company provides no post-retirement benefits to its former employees
other than the continuation of flight benefits on a stand-by, non-revenue basis;
the cost of which is not material. Additional, no material post-employment
benefits are provided.
    
 
   
(7) CONVERTIBLE PREFERRED STOCK
    
 
   
     Annual dividends of $5.41 per share are payable quarterly on the 291,149
shares of voting Series B 10.5% convertible preferred stock. Each preferred
share is entitled to four votes and may be converted into four shares of common
stock subject to certain anti-dilution provisions. The preferred shares are
redeemable at the Company's election, if the price of common stock is at least
$19.32 per share, at $51.52 per share plus unpaid accrued dividends plus a

(8) COMMON STOCK
    
 
   
     Certain "Rights" have been distributed to certain shareholders of record on
August 25, 1986. The Rights, which entitle the holder to purchase one
one-hundredth ( 1/100th) of a share of Series D Participating Preferred Stock at
a price of $200, are not exercisable unless certain conditions relating to a
possible attempt to acquire the Company are met. In the event of an acquisition
or merger, the Rights will entitle the holder of a Right to purchase that number
of common shares of the acquiring or surviving entity having twice the market
value of the exercise price of each Right. The Rights expire on August 24, 1996
and are redeemable at a price of $.03 per Right under certain conditions.

     During 1991, the Company restructured its lease commitment for Airbus A320
aircraft with the lessors. As a result of the restructuring, the Company's
obligation to lease ten A320 aircraft was canceled and the basic rental rate for
twelve aircraft was revised to provide for the repayment to the lessor over a
ten-year period of certain advanced credits received by the Company which relate
to the ten canceled aircraft.
    
 
   
     In the third quarter of 1991, the Company requested a deferral of rent and
other periodic payments from its aircraft providers. The deferral was requested
in an effort to conserve cash and improve the Company's liquidity position. As a
condition of securing the $78 million D.I.P. financing, the Company was required
to obtain from most aircraft providers rent, principal and interest payment
deferrals in excess of $100 million covering the six-month period of June
through November 1991. These deferrals will generally be repaid with

     In the third quarter of 1992, the Company requested an additional deferral
of rent and other periodic payments from its aircraft providers. The deferral
was requested to assure sufficient liquidity to sustain operations while
additional debtor-in-possession financing was obtained (note 4). The 1992
deferrals will generally be repaid either without interest during the first
quarter of 1993 or with interest over a period of seven years. At December 31,

of credit are collateralized by certain spare rotable parts with a net book
value of $35.8 million and $17.6 million in restricted cash.
    
 
   
     Rent expense (excluding landing fees) was approximately $245 million in
1993, $307 million in 1992 and $319 million in 1991.

     (b) Revenue Bonds
    
 
   
     Special facility revenue bonds have been issued by a municipality used for
leasehold improvements at the airport which have been leased by the Company.
Under the operating lease agreements, which commenced in 1990, the Company is
required to make rental payments sufficient to pay principal and interest when
due on the bonds. The Company ceased rental payments in June 1991. The principal
amount of such bonds outstanding at December 31, 1992 and 1991 was $40.7
million. In October 1993, the Company and the bondholder agreed to reduce the
outstanding balance of the bonds to $22.5 million and adjust the related
operating lease payments sufficient to pay principal and interest on the reduced
amount effective upon the confirmation of a plan of reorganization. The
remaining principal balance of $18.2 million will be accorded the same treatment
under the plan of reorganization as a pre-petition unsecured claim. The Company
also agreed to make adequate protection payments in the amount of $150,000 per
month from August 1993 to plan confirmation.
    
 
   
     (c) Aircraft Acquisitions
    
 
   
     At December 31, 1993, the Company had on order a total of 93 aircraft of
the types currently comprising the Company's fleet, of which 51 are firm and 42
are options. The table below details such deliveries.

     The current estimated aggregate cost for these firm commitments and options
is approximately $5.2 billion. Future aircraft deliveries are planned in some
instances for incremental additions to the Company's existing aircraft fleet and
in other instances as replacements for aircraft with lease terminations
occurring during this period. The purchase agreements to acquire 24 Boeing
737-300 aircraft had been affirmed in the Company's bankruptcy proceeding. With
timely notice to the manufacturer, all or some of these deliveries may be
converted to Boeing 737-400 aircraft. At December 31, 1993, eight Boeing 737
delivery positions had been eliminated due to the lack of a required
reconfirmation notice by the Company to Boeing leaving 16 delivery positions as
reflected above. The failure to reconfirm such delivery positions exposes the
Company to loss of pre-delivery deposits and other claims which may be asserted
by Boeing in the bankruptcy proceeding. The purchase agreements for the
remaining aircraft types have not been assumed, and the Company has not yet
determined which of the other aircraft purchase agreements, if any, will be
affirmed or rejected.
    
 
   
     As part of the $68.4 million term loan (see note 4(a)), the Company
terminated an agreement to lease 24 Airbus A320 aircraft and ultimately replaced
it with a put agreement to lease up to four such aircraft. The lessor is under
no obligation to lease such aircraft to the Company and has the right to
remarket these aircraft to other parties. Prior to its bankruptcy filing, the
Company also entered into a similar arrangement with another lessor, whereby the
Company terminated its agreement to lease 10 Airbus A320 aircraft and replaced
it with a put agreement to lease up to 10 Airbus A320 aircraft.
    
 
   
     The put agreement related to the term loan requires the lessor to notify
the Company prior to July 1, 1994 if it intends to require the Company to lease
any of its put aircraft. The other put agreement requires 180 days prior notice
of the delivery of a put aircraft. The agreement also provides that the lessor
may not put more than five aircraft to the Company in any one calendar year.
This put right expires on December 31, 1996. No more than nine put aircraft
(from both lessors combined) may be put to the Company in one calendar year. The
put aircraft are reflected in the "Firm Orders" section of the table above.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
     The Investment Agreement provides that as partial consideration for the
cancellation of certain put rights, the lessor will receive the right to require
the Company to lease up to eight aircraft prior to June 30, 1999.
    
 
   
     The Company does not have firm lease or debt financing commitments with
respect to the future scheduled aircraft deliveries (other than for the put
aircraft referred to above).
    
 
   
     In addition to the aircraft set forth in the chart above, the Company also
has a pre-petition executory contract under which the Company holds delivery
positions for four Boeing 747-400 aircraft under firm orders and another four
under options. The contract allows the Company, with the giving of adequate
notice, to substitute other Boeing aircraft types for the Boeing 747-400 in
these delivery positions. As a result, the Company is still evaluating its
future fleet needs and is currently unable to determine if it will substitute
other aircraft types or reject this agreement.
    
 
   
     (d) Concentration of Credit Risk
    
 
   
     The Company does not believe it is subject to any significant concentration
of credit risk. At December 31, 1993, approximately 82% of the Company's
receivables related to tickets sold to individual passengers through the use of
major credit cards or to tickets sold by other airlines and used by passengers
on America West. These receivables are short-term, generally being settled
shortly after sale or in the month following usage. Bad debt losses, which have
been minimum in the past, have been considered in establishing allowances for
doubtful accounts.
    
 
   
(12) RELATED PARTY TRANSACTIONS
    
 
   
     During 1989, the Company sold 486,219 shares of common stock at $6.31 and
$9.79 to the stockholder that purchased 3,029,235 shares of common stock at
$10.50 in 1987 and $1 million of the Series C preferred stock in 1985. This
stockholder has the right to maintain a 20% voting interest through the purchase
of common stock from the Company at a price per share which is the average
market price per share for the preceding six months. In 1990, the stockholder
made direct purchases on the open market to maintain its 20% voting interest. On
February 15, 1991, the stockholder purchased 253,422 shares of common stock from
the Company at $5.50 per share. No such purchases occurred in 1993 or 1992.
    
 
   
     The Company has entered into various aircraft acquisition and leasing
agreements with this stockholder at terms comparable to those obtained from
third parties for similar transactions. The Company leases 11 aircraft from this
stockholder and the rental payments for such leases amounted to $33.7 million in
1993, $33.8 million in 1992 and $18.1 million in 1991. At December 31, 1993, the
Company was obligated to pay $232 million under these leases through August 2003
unless terminated earlier at the stockholder's option. In 1991, the stockholder
drew upon a $7.5 million letter of credit which had been issued in its favor in
lieu of a cash reserve for periodic heavy maintenance overhauls. This cash
deposit is included in other assets at December 31, 1993 and 1992.
    
 
   
     In addition, the stockholder participated as a lender in the September 1992
D.I.P. Facility and advanced $10 million of the $53 million in total D.I.P
financing. In September 1993, the stockholder was repaid the then outstanding
balance of $8.3 million as a result of not participating in the extension of the
maturity date of the debt financing.
    
 
   
     In order to assist the Chairman of the Board with certain costs associated
with his service as chairman, the Company pays an office overhead allowance of
$4,167 per month to a company owned by the chairman. During 1993 and 1992, such
payments totaled approximately $50,000 and $16,000, respectively.
    
 
   
     Additionally, a former member of the Board of Directors provided consulting
services to the Company during 1993 and 1992 for which he received fees of
approximately $39,000 and $47,000, respectively.

</TABLE>
    
 
   
     The restructuring charges were necessitated by aircraft fleet reductions
and other operational changes. The Company has reduced its fleet to 85 aircraft
and has reduced the number of aircraft types in the fleet from five to three.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145 of the Delaware General Corporation Law ("DGCL") authorizes,
inter alia, a corporation generally to indemnify any person ("indemnitee") who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding (other than an action by or in the right
of the corporation) by reason of the fact that such person is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation, in a similar position with another corporation or
entity, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him in connection
with such action, suit or proceeding if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. With respect to actions or
suits by or in the right of the corporation; however, an indemnitee who acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation is generally limited to attorneys' fees and
other expenses, and no indemnification shall be made if such person is adjudged
liable to the corporation unless and only to the extent that a court of
competent jurisdiction determines that indemnification is appropriate. Section
145 further provides that any indemnification shall be made by the corporation
only as authorized in each specific case upon a determination by the (i)
stockholders, (ii) board of directors by a majority vote of a quorum of
disinterested directors so directs, that indemnification of the indemnitee is
proper because he has met the applicable standard of conduct. Section 145
provides that indemnification pursuant to its provisions is not exclusive of
other rights of indemnification to which a person may be entitled under any
by-law agreement, vote of stockholders or disinterested directors or otherwise.
 
     Section 8.02 of the Company's By-laws, a copy of which is filed as Exhibit
3.2 to this Registration Statement provides, in substance, that directors,
officers, employees and agents shall be indemnified to the fullest extent
permitted by Section 145 of the DGCL.
 
     Article 12.0 of the Company's Restated Certificate of Incorporation, a copy
of which is filed as Exhibit 3.1 to this Registration Statement, limits the
liability of directors of the Company to the Company or its stockholders (in
their capacity as directors but not in their capacity as officers) to the
fullest extent permitted by the DGCL. Specifically, directors of the Company
will not be personally liable for monetary damages for
 
                                      II-1

breach of a director's fiduciary duty as a director, except for liability (i)
for any breach of the director's duty of loyalty to the Company or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) for unlawful
payments of dividends or unlawful stock repurchase or redemptions as provided in
section 174 of the DGCL or (iv) for any transaction from which the director
derived an improper personal benefit. The Restated Certificate of Incorporation
also provides that if the DGCL is amended after the approval of the Restated
Certificate of Incorporation to authorize corporate action further eliminating
or limiting the personal liability of directors, then the liability of a
director of the Company will be eliminated or limited to the full extent
permitted by the DGCL, as so amended.
 
     The form of the Third Revised Investment Agreement filed as Exhibit 10.1 to
this Registration Statement contains certain provisions for indemnification of
directors and officers of the Company and the Selling Securityholder against
civil liabilities under the Securities Act. Certain of these provisions are set
forth in the form of the Registration Rights Agreement filed as Exhibit 4.6 to
this Registration Rights Agreement.
 
     The Company intends to enter into indemnification agreements with certain
of its directors providing for indemnification to the fullest extent permitted
by the laws of the State of Delaware. These agreements provide for specific
procedures to better assure the directors' rights to indemnification, including
procedures for directors to submit claims, for determination of directors
entitled to indemnification (including the allocation of the burden of proof and
selection of a reviewing party) and for enforcement of directors'
indemnification rights.

ITEM 17.  UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes: (1) to file, during any
period in which offers or sales are being made, a post-effective amendment to
this registration statement: (i) to include any prospectus required by section
10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any
facts or events arising after the effective date of the registration statement
(or the most recent post-effective amendment thereof) which, individually or in
the aggregate, represent a fundamental change in the information set forth in
the registration statement; (iii) to include any material information with
respect to the plan of distribution not previously disclosed in the registration
statement or any material change to such information in the registration
statement.
 
     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

             INDEPENDENT AUDITORS' REPORT ON SCHEDULES AND CONSENT
 
The Board of Directors and Stockholders
America West Airlines, Inc. D.I.P.:
 
     The audits referred to in our report dated March 18, 1994 included the
related financial statement schedules as of December 31, 1993, and for each of
the years in the three-year period ended December 31, 1993, included in the
registration statement. These financial statement schedules are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statement schedules based on our audits. In our
opinion, such financial statement schedules, when considered in relation to the
basic financial statements taken as a whole, present fairly in all material
respects the information set forth therein.
 
     We consent to the use of our reports included herein and to the reference
to our firm under the heading "Experts" in the prospectus.
 
     Our report dated March 18, 1994, referenced to above, contains an
explanatory paragraph that states that America West's Chapter 11 proceeding,
significant losses, accumulated deficit and highly leveraged capital structure
raise substantial doubt about its ability to continue as a going concern. The
financial statements and financial statement schedules do not include any
adjustments that might result from the outcome of these uncertainties.

Trustee and any agent of the Company or the Trustee such security or indemnity
as may be required by them to indemnify and defend and to save each of them
harmless and, in every case of destruction, loss or theft, evidence to their
satisfaction of the destruction, loss or theft of such Security and of the
ownership thereof and in the case of mutilation or defacement, shall surrender
the Security to the Trustee or such agent.
    
 
     Upon the issuance of any substitute Security, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses (including the fees
and expenses of the Trustee or its agent) connected therewith. In case any
Security that has matured or is about to mature or has been called for
redemption in full shall become mutilated or defaced or be destroyed, lost or
stolen, the Company may, instead of issuing a substitute Security, pay or
authorize the payment of the same (without surrender thereof except in the case
of a mutilated or defaced Security), if the applicant for such payment shall
furnish to the Company and to the Trustee and any agent of the Company or the
Trustee such security or indemnity as any of them may require to save each of
them harmless, and, in every case of destruction, loss or theft, the applicant
shall also furnish to the Company and the Trustee and
 
                                       11
<PAGE>   18
 
any agent of the Company or the Trustee evidence to their satisfaction of the
destruction, loss or theft of such Security and of the ownership thereof.
 
     Every substitute Security issued pursuant to the provisions of this Section
2.6 by virtue of the fact that any such Security is destroyed, lost or stolen
shall constitute an additional contractual obligation of the Company whether or
not the destroyed, lost or stolen Security shall be at any time enforceable by
anyone and shall be entitled to all the benefits of (but shall be subject to all
the limitations of rights set forth in) this Indenture equally and
proportionately with any and all other Securities duly authenticated and
delivered hereunder. All Securities shall be held and owned upon the express
condition that, to the extent permitted by law, the foregoing provisions are
exclusive with respect to the replacement or payment of mutilated, defaced or
destroyed, lost or stolen Securities and shall preclude any and all other rights
or remedies notwithstanding any law or statute existing or hereafter enacted to
the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.
 
     SECTION 2.7  Cancellation of Securities; Destruction Thereof.
 
          (a) All Securities surrendered for payment, redemption, registration
     of transfer or exchange, if surrendered to the Company or any agent of the
     Company or any agent of the Trustee, shall be delivered to the Trustee for
     cancellation and, upon receipt thereof by the Trustee, shall be cancelled
     by it; and no Securities shall be issued in lieu thereof except as
     expressly permitted by any of the provisions of this Indenture. The Trustee
     shall destroy cancelled Securities held by it and deliver a certificate of
     destruction to the Company. If the Company or any agent of the Company
     shall acquire any of the Securities, such acquisition shall not operate as
     a redemption or satisfaction of the indebtedness represented by such
     Securities unless and until the same are delivered to the Trustee for
     cancellation.
 
          (b) At such time as all beneficial interests in a Global Security have
     either been exchanged for Securities in non-global form, redeemed,
     repurchased or cancelled, such Global Security shall be returned to and
     cancelled by the Trustee. At any time prior to such cancellation, if any
     beneficial interest in a Global Security is exchanged for Securities in
     non-global form, redeemed, repurchased or cancelled, the principal amount
     of Securities represented by such Global Security shall be reduced and an
     endorsement shall be made on such Global Security by the Trustee to reflect
     such reduction.
 
     SECTION 2.8  Temporary Securities.  Until definitive Securities are ready
for delivery, the Company may prepare and the Trustee shall authenticate
temporary Securities. Temporary Securities shall be substantially in the form of
definitive Securities but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee, upon receipt of a written order signed by two
Officers of the Company, shall authenticate definitive Securities in exchange
for temporary Securities. Until such exchange, temporary Securities shall be
entitled to the same rights, benefits and privileges as definitive Securities.
 
     SECTION 2.9  Currency and Manner of Payments in Respect of
Securities.  Payment of the principal of and premium (if any) and interest on,
any Security will be made in U.S. Legal Tender.
 
     SECTION 2.10  CUSIP Number.  A "CUSIP" number will be printed on the
Securities, and the Trustee shall use the CUSIP number in notices of redemption,
purchase or exchange as a convenience to Holders, provided that any such notice
may state that no representation is made as to the correctness or accuracy of
the CUSIP number printed in the notice or on the Securities and that reliance
may be placed only on the other identification numbers printed on the
Securities. The Company will promptly notify the Trustee of any change in the
CUSIP number.

                                  REDEMPTIONS
 
   
     SECTION 3.1  Notices to Trustee.  If the Company elects to redeem
Securities pursuant to Section 3.7 or is required to redeem Securities pursuant
to Section 3.8 it shall furnish to the Trustee, at least 10 but not more than 15
days before notice of any redemption is to be mailed to Holders (or such shorter
time as
    
 
                                       12
<PAGE>   19
 
   
may be satisfactory to the Trustee), an Officers' Certificate stating that the
Company has elected to redeem Securities pursuant to Section 3.7 or is required
to redeem Securities pursuant to Section 3.8, as the case may be, the date
notice of redemption is to be mailed to Holders, the Redemption Date, the
aggregate principal amount of Securities to be redeemed, the Redemption Price
for such Securities and the amount of accrued and unpaid interest on such
Securities as of the Redemption Date. If the Trustee is not the registrar for
the Securities, the Company shall, concurrently with delivery of its notice to
the Trustee of a redemption, cause the registrar for the Securities to deliver
to the Trustee a certificate (upon which the Trustee may rely) setting forth the
name of, and the aggregate principal amount of Securities held by each Holder.
The Company will also provide the Trustee with any additional information that
the Trustee reasonably requests in connection with any redemption.
    
 
     SECTION 3.2  Selection of Securities to be Redeemed.  If less than all
outstanding Securities are to be redeemed, the Company shall select the
outstanding Securities to be redeemed or accepted for payment in compliance with
the requirements of the principal national securities exchange, if any, on which
the Securities are listed or, if the Securities are not listed on a securities
exchange, on a pro rata basis, by lot or by any other method that the Trustee
deems fair and appropriate. If the Company elects to mail notice of a redemption
to Holders, the Trustee shall, at least 5 days prior to the date notice of
redemption is to be mailed, (i) select the Securities to be redeemed from
Securities Outstanding not previously called for redemption, and (ii) promptly
notify the Company of the names of each Holder of Securities selected for
redemption, the principal amount of Securities held by each such Holder and the
principal amount of such Holder's Securities that are to be redeemed. The
Trustee shall select for redemption Securities or portions of Securities in
principal amounts of $1,000 or integral multiples of $1,000; except that if all
of the Securities of a Holder are selected for redemption, the aggregate
principal amount of the Securities held by such Holder, even if not a multiple
of $1,000, may be redeemed. Except as provided in the preceding sentence,
provisions of this Indenture that apply to Securities called for redemption also
apply to portions of Securities called for redemption.
 
     SECTION 3.3  Notice of Redemption.
 
          (a) At least 30 days but not more than 60 days before any Redemption
     Date, the Company shall mail by first class mail to each such Holder's
     registered address a notice of redemption to each Holder of Securities or
     portions thereof that are to be redeemed. With respect to any redemption of
     Securities, the notice shall identify the Securities or portions thereof to
     be redeemed and shall state: (1) the Redemption Date; (2) the Redemption
     Price for the Securities and the amount of unpaid and accrued interest on
     such Securities as of the date of redemption; (3) if any Security is being
     redeemed in part, the portion of the principal amount of such Security to
     be redeemed and that, after the Redemption Date, upon surrender of such
     Security, a new Security or Securities in principal amount equal to the
     unredeemed portion will be delivered; (4) the name and address of the
     Paying Agent; (5) that Securities called for redemption must be surrendered
     to the Paying Agent to collect the Redemption Price for, and any accrued
     and unpaid interest on, such Securities; (6) that, unless the Company
     defaults in making such redemption payment, interest on Securities called
     for redemption ceases to accrue on and after the Redemption Date and the
     only remaining right of the Holders of such Securities is to receive
     payment of the Redemption Price upon surrender to the Paying Agent of the
     Securities redeemed; and (7) if fewer than all the Securities are to be
     redeemed, the identification of the particular Securities (or portions
     thereof) to be redeemed, as well as the aggregate principal amount of
     Securities to be redeemed and the aggregate principal amount of Securities
     to be outstanding after such partial redemption.
 
          (b) At the Company's request, the Trustee shall (at the Company's
     expense) give the notice of any redemption to Holders; provided, however,
     that the Company shall deliver to the Trustee, at least 10 days prior to
     the date that notice of the redemption is to be mailed to Holders, an
     Officers' Certificate that (i) requests the Trustee to give notice of the
     redemption to Holders, (ii) sets forth the information to be provided to
     Holders in the notice of redemption, as set forth in the preceding
     paragraph, and (iii) sets forth the aggregate principal amount of
     Securities to be redeemed and the amount of accrued and unpaid interest
     thereon as of the redemption date. If the Trustee is not the registrar for
     the Securities, the Company shall, concurrently with any such request,
     cause the registrar for the Securities to deliver to the Trustee a
     certificate (upon which the Trustee may rely) setting forth the name of,
     the address of, and the
 
                                       13
<PAGE>   20
 
     aggregate principal amount of Securities held by, each Holder; provided
     further that any such Officers' Certificate may be delivered to the Trustee
     on a date later than permitted under this Section 3.3(b) if such later date
     is acceptable to the Trustee.
 
     SECTION 3.4  Effect of Notice of Redemption.  Once notice of redemption is
mailed to the Holders, Securities called for redemption shall become due and
payable on the Redemption Date at the Redemption Price. Upon surrender to the
Trustee or the Paying Agent, the Securities called for redemption shall be paid
at the Redemption Price.
 
     SECTION 3.5  Deposit of Redemption Price.
 
          (a) On or prior to any Redemption Date, the Company shall deposit with
     the Paying Agent money sufficient to pay the Redemption Price of, and
     accrued interest on, all Securities to be redeemed on that date. After any
     Redemption Date, the Trustee or the Paying Agent shall promptly return to
     the Company any money that the Company deposited with the Trustee or the
     Paying Agent in excess of the amounts necessary to pay the Redemption Price
     of, and accrued interest on, all Securities to be redeemed.
 
          (b) If the Company complies with the preceding paragraph, unless the
     Company defaults in the payment of such Redemption Price, interest on the
     Securities to be redeemed will cease to accrue on such Securities on the
     applicable Redemption Date, whether or not such Securities are presented
     for payment. If a Security is redeemed on or after an interest record date
     but on or prior to the related Interest Payment Date, then any accrued and
     unpaid interest shall be paid to the Person in whose name such Security was
     registered at the close of business on such record date. If any Security
     called for redemption shall not be so paid upon surrender for redemption
     because of the failure of the Company to comply with the preceding
     paragraph, interest will be paid on the unpaid principal and interest from
     the redemption date until such principal and interest is paid, at the rate
     of interest provided in the Securities and Section 4.1.
 
     SECTION 3.6  Securities Redeemed in Part.  Upon surrender of a Security
that is redeemed in part, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder at the Company's expense a new Security
equal in principal amount to the unredeemed portion of the Security surrendered.
If a Global Security is so surrendered, such new Security so issued shall be a
new Global Security.
 
     SECTION 3.7  Optional Redemption.  The Company, at its option on notice to
the Holders as provided herein, may redeem the Securities:
 
          (a) prior to             , 1997
 
             (i) at any time in whole but not in part, at a Redemption Price
        equal to 105% of the aggregate principal amount of the Securities then
        Outstanding, plus accrued and unpaid interest thereon to the Redemption
        Date; or
 
   
             (ii) from time to time in part from the Net Offering Proceeds
        received by the Company prior to             , 1997 from one or more
        Public Offering Sales at a Redemption Price equal to 105% of the
        aggregate principal amount of the Securities so redeemed, plus accrued
        and unpaid interest thereon to the Redemption Date, except for amounts
        redeemed under Section 3.8 hereof; and
    
 
          (b) on and after             , 1997, at any time in whole or from time
     to time in part, at a Redemption Price equal to the applicable percentage
     of the aggregate principal amount of the Securities so to be redeemed, set
     forth below, plus accrued and unpaid interest thereon to the Redemption
     Date.

     SECTION 3.8  Mandatory Redemption.  In the event that, prior to
               , 1997, the Company consummates a Public Offering Sale and
immediately prior to such consummation the Company has cash and Cash
Equivalents, not subject to any restriction on disposition (other than any such
restriction imposed by this Indenture), of at least $100,000,000, then the
Company shall redeem Securities at a Redemption Price equal to 104% of the
aggregate principal amount of the Securities so redeemed, plus accrued and
unpaid interest to the Redemption Date. The aggregate Redemption Price and
accrued and unpaid interest of the Securities to be so redeemed shall equal the
lesser of (a) 50% of the Net Offering Proceeds of such Public Offering Sale and
(b) the excess, if any, of (i) $20,000,000 over (ii) the amount of any Net
Offering Proceeds of any prior Public Offering Sale received to                ,
1997 and applied to redeem Securities pursuant to this Section 3.8.

                            COVENANTS OF THE COMPANY
 
     SECTION 4.1  Payment of Principal and Interest.  The Company covenants and
agrees that it will duly and punctually pay or cause to be paid the principal
of, premium (if any) and interest on, each of the Securities at the place or
places, at the respective times and in the manner provided in such Securities
and in this Indenture. To the extent lawful, the Company shall pay interest on
overdue principal, premium and interest at a rate equal to the then applicable
interest rate on the Securities, compounded semi-annually.
 
     SECTION 4.2  Offices for Payments, etc.  So long as any Securities are
authorized for issuance pursuant to this Indenture or are outstanding hereunder,
the Company will maintain in the Borough of Manhattan, the City of New York, an
office or agency where the Securities may be presented for payment and for
exchange and registration of transfer as in this Indenture provided. The Company
will give prompt written notice to the Trustee of any change in the location of
such office or agency. Until the Company shall furnish to the Trustee a
different address therefor, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office of the Trustee as specified
in Section 12.4 hereof.
 
     The Company may also from time to time designate one or more other offices
or agencies where the Securities may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York, for such purposes. The Company will give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.
 
     SECTION 4.3  Appointment to Fill a Vacancy in Office of Trustee.  The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 8.9, a Trustee so that there
shall at all times be a Trustee with respect to the Securities.
 
     SECTION 4.4  Paying Agents.  Whenever the Company shall appoint a Paying
Agent other than the Trustee with respect to the Securities, it will cause such
Paying Agent to execute and deliver to the Trustee an instrument in which such
agent shall agree with the Trustee, subject to the provisions of this Section
4.4,
 
          (a) that it will hold all sums received by it as such agent for the
     payment of the principal of, premium (if any) and interest on the
     Securities (whether such sums have been paid to it by the Company or any
     other obligor on the Securities) in trust for the benefit of the Holders of
     the Securities or of the Trustee,
 
          (b) that it will give the Trustee notice of any failure by the Company
     (or by any other obligor on the Securities) to make any payment of the
     principal of, premium (if any) or interest on the Securities when the same
     shall be due and payable, and
 
          (c) that it will pay any such sums so held in trust by it to the
     Trustee upon the Trustee's written request, at any time during the
     continuance of the failure referred to in clause (b) above.
 
                                       15
<PAGE>   22
 
     The Company will, on or prior to each due date of the principal of, premium
(if any) or interest on the Securities, deposit with the Paying Agent a sum
sufficient to pay such principal, premium or interest so becoming due, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the
Trustee of any failure to take such action.
 
     If the Company shall act as its own Paying Agent with respect to the
Securities it will, on or before each due date of the principal of, premium (if
any) or interest on the Securities set aside, segregate and hold in trust for
the benefit of the Holders of the Securities a sum sufficient to pay such amount
so becoming due. The Company will promptly notify the Trustee of any failure to
take such action.
 
     Anything in this Section 4.4 to the contrary notwithstanding, but subject
to Section 11.1, the Company may at any time, for the purpose of obtaining a
satisfaction and discharge with respect to the Securities or for any other
reason, pay or cause to be paid to the Trustee all sums held in trust with
respect to the Securities by the Company or any Paying Agent hereunder, as
required by this Section, such sums to be held by the Trustee upon the trusts
herein contained.
 
     Anything in this Section 4.4 to the contrary notwithstanding, the agreement
to hold sums in trust as provided in this Section 4.4 is subject to the
provisions of Sections 11.3 and 11.4 hereof.
 
     SECTION 4.5  Reports and Information.
 
          (a) The Company will furnish to the Trustee within 120 days after the
     end of each fiscal year an Officers' Certificate stating that (i) a review
     of the activities of the Company and its Subsidiaries during the preceding
     fiscal year has been made to determine whether the Company has kept,
     observed, performed and fulfilled all of its obligations under this
     Indenture and the Securities, (ii) such review was supervised by the
     Officers of the Company signing such certificate, and (iii) that to the
     best knowledge of each Officer signing such certificate, (A) during such
     year the Company has kept, observed, performed and fulfilled each and every
     covenant contained in this Indenture and is not in default in the
     performance or observance of any of the terms, provisions and conditions of
     this Indenture (or, if a Default or Event of Default occurred, describing
     all such Defaults or Events of Default of which each such Officer may have
     knowledge and what action the Company has taken or proposes to take with
     respect thereto), and (B) no event has occurred and remains in existence by
     reason of which payments on account of the principal of, premium (if any)
     or interest on, the Securities are prohibited or if such event has
     occurred, a description of the event and what action the Company is taking
     or proposes to take with respect thereto. The Company will, so long as any
     of the Securities are outstanding, deliver to the Trustee, promptly after
     any Officer of the Company becomes aware of (i) any Default or Event of
     Default, or (ii) any default or event of default under any issue of
     Indebtedness that could result in an Event of Default under Section 7.1, an
     Officers' Certificate specifying such Default, Event of Default or default
     and what action the Company is taking or proposes to take with respect
     thereto.
 
          (b) If the Company is subject to the requirements of Section 13 or
     15(d) of the Exchange Act, the Company shall file with the Commission all
     quarterly and annual reports and such other information, documents or other
     reports (or copies of such portions of any of the foregoing as the
     Commission may by rules and regulations prescribe) required to be filed
     pursuant to such provisions of the Exchange Act. The Company shall file
     with the Trustee, within 5 days after it files the same with the
     Commission, copies of the quarterly and annual reports and such other
     information, documents, and reports (or copies of such portions of any of
     the foregoing as the Commission may by rules and regulations prescribe)
     that it files with the Commission as contemplated by this Section 4.5(b).
     The Company shall also comply with the other provisions of Section 314(a)
     of the TIA. If the Company is not required to file the aforementioned
     reports, the Company (at its own expense) shall file with the Trustee and
     mail, or cause the Trustee to mail, to Holders at their addresses appearing
     in the register of Securities at the time of such mailing within 5 days
     after it would have been required to file such information with the
     Commission, all information and financial statements, including any notes
     thereto and with respect to annual reports, an auditors' report by an
     accounting firm of established national reputation, and a "Management's
     Discussion and Analysis of Financial Condition and Results of Operations,"
     comparable to the disclosure that the Company would have been required to
     include in annual and quarterly reports, information,
 
                                       16
<PAGE>   23
 
     documents or other reports, including, without limitation, reports on Forms
     10-K, 10-Q and 8-K, if the Company was subject to the requirements of
     Section 13 or 15(d) of the Exchange Act.
 
     SECTION 4.6  Corporate Existence.  Subject to Article Six, the Company will
do or cause to be done all things necessary to preserve and keep in full force
and effect its corporate existence and the corporate, partnership or other
existence of each Subsidiary of the Company and the rights (charter and
statutory) and franchises of the Company and any Subsidiary of the Company;
provided, that the Company shall not be required to preserve any such corporate,
partnership or other existence of any Subsidiary or any such right or franchise,
if the Board of Directors of the Company shall determine in the exercise of its
business judgment that the preservation thereof is no longer desirable in the
conduct of the business of the Company or any Subsidiary and that abandonment of
any such right or franchise shall have no material adverse effect on the Company
and its Subsidiaries taken as a whole, or the Holders.
 
     SECTION 4.7  Payment of Taxes and Other Claims.  The Company will pay or
discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon the Company or any Subsidiary or upon the income, profits or
property of the Company or any Subsidiary, and (2) all lawful claims for labor,
materials and supplies that, if unpaid, might by law become a lien upon the
property of the Company, or any Subsidiary; provided, however, that the Company
shall not be required to pay or discharge or cause to be paid or discharged any
such tax, assessment, charge or claim the amount, applicability or validity of
which is being contested in good faith by appropriate proceedings and with
respect to which an adequate reserve has been established by the Company to the
extent required by GAAP.
 
     SECTION 4.8  Maintenance of Properties.  The Company shall, and shall cause
each of its Subsidiaries to, maintain all properties used or useful in the
conduct of its business in good condition, repair and working order and supply
such properties with all necessary equipment and make all necessary repairs,
renewals, replacements, betterments and improvements thereto, all as in the
judgment of the Company may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times;
provided, however, that nothing in this Section shall prevent the Company or any
Subsidiary from discontinuing the operation and maintenance of any of such
properties if such discontinuance is, in the good faith judgment of the Company
or such Subsidiary, as the case may be, desirable in the conduct of its
respective business and not disadvantageous in any material respect to the
Holders.
 
     SECTION 4.9  Maintenance of Insurance.  The Company will insure and keep
insured, and will cause each Subsidiary to insure and keep insured, with
reputable insurance companies, such of their respective properties, to such an
extent and against such risks, and will maintain liability insurance, to the
extent that property of a similar character is usually so insured by companies
engaged in a similar business and owning similar properties in accordance with
good business practice.
 
     SECTION 4.10  Compliance with Laws.  The Company shall comply, and shall
cause each of its Subsidiaries to comply, with all applicable statutes, rules,
regulations, orders and restrictions of the United States of America, all states

board, regulatory authority, bureau, agency and instrumentality of the
foregoing, in respect of the conduct of their respective businesses and the
ownership of their respective properties, except such as are being contested in
good faith and by appropriate proceedings and except for such noncompliance as
would not in the aggregate have a material adverse effect on the Company and its
Subsidiaries, taken as a whole.

        the right to require the Company to purchase all or any part of such
        Holder's Securities at a purchase price in cash equal to 101% of the
        principal amount thereof plus accrued and unpaid interest, if any, to

        relevant record date to receive interest due on the relevant interest
        payment date);
    
 
   
             (ii) the circumstances and relevant facts regarding such Change of
        Control;
    
 
   
             (iii) the purchase date (which shall be no earlier than 30 days nor
        later than 60 days from the date such notice is mailed; and
    
 
   
             (iv) the instructions, consistent with this Section 4.11, that the
        Company determines that a Holder must follow to have its Securities
        repurchased.
    
 
   
          (c) Holders electing to have a Security purchased will be required to
     surrender the Security, with an appropriate form duly completed, to the
     Company at the address specified in the notice at least 10 Business Days
     prior to the purchase date. Holders will be entitled to withdraw their
     election if the Company receives not later than three Business Days prior

     setting forth the name of the holder, the principal amount of the Security
     which was delivered for purchase by the Holder and a statement that such
     Holder is withdrawing his election to have such Security purchased.
    
 
   
          (d) On the purchase date, all Securities purchased by the Company
     under this Section shall be delivered by the Company to the Trustee for
     cancellation, together with an Officer's Certificate requesting such
     cancellation and stating that they are being delivered for cancellation in
     accordance with the terms of this Section 4.11 and that the Company shall

     the Exchange Act and any other securities laws or regulations in connection
     with the repurchase of Securities pursuant to this Section 4.11. To the
     extent that the provisions of any securities laws or regulations conflict
     with provisions of this Section 4.11, the Company shall comply with the
     applicable securities laws and regulations and shall not be deemed to have
     breached its obligations under this Section 4.11 by virtue thereof.
    
 
   
          (f) The Trustee shall be under no obligation to ascertain the

     other than as provided above, upon receipt of the written notice of Change
     of Control from the Company. The Trustee may conclusively assume, in the
     absence of written notice to the contrary from the Company, that no Change
     of Control has occurred.
    
 
   
     SECTION 4.12  Limitation on Issuances and Dispositions of Capital Stock of
Subsidiaries.  Each Subsidiary of the Company shall at all times be a Wholly
Owned Subsidiary of the Company. The Company (i) shall not, and shall not permit

             (i) declare or pay any dividends on or make any distributions in
        respect of the Capital Stock of the Company (other than dividends or
        distributions payable solely in shares of Capital Stock (other than
        Redeemable Stock) or in options, warrants, or other rights to purchase

        of the Company;
 
   
             (ii) purchase, redeem or otherwise acquire or retire for value
        (other than through the issuance solely of Capital Stock (other than

        warrants, rights (other than exchangeable or convertible Indebtedness of
        the Company not prohibited under clause (iii) below) or options to
        acquire Capital Stock of the Company; or
    
 
   
             (iii) redeem, repurchase, defease (including, but not limited to,
        in substance or legal defeasance), or otherwise acquire or retire for
        value (other than through the issuance solely of Capital Stock (other
        than Redeemable Stock) or warrants, rights or options to acquire Capital
        Stock (other than Redeemable Stock)) (collectively, a "prepayment"),
        directly or indirectly (including by way of amendment of the terms of
        any Indebtedness in connection with any retirement or acquisition of
        such Indebtedness), other than at any scheduled maturity thereof or by
        any scheduled repayment or scheduled sinking fund payment, any
        Indebtedness of the Company which is subordinated in right of payment to
        the Securities or which matures after the maturity date of the
        Securities (except out of the proceeds of Refinancing Indebtedness);
    
 
     if, at the time of such transaction described in clause (i), (ii) or (iii)
     (such transactions being hereinafter collectively referred to as
     "Restricted Payments") or after giving effect thereto, either (x) a Default
     or an Event of Default shall have occurred and be continuing or (y) the
     aggregate amount expended by the Company and its Subsidiaries for all
     Restricted Payments (the amount of any Restricted Payment if other than
     cash to be the fair market value of the property included in such payment
     as determined in good faith by the Board of Directors as evidenced by a
     Board Resolution) from and after the Closing Date shall exceed the sum of
     (A) 50% (or, if the Securities at the time of the proposed Restricted
     Payment are rated Investment Grade by both S&P and Moody's, 75%) of the
     aggregate Adjusted Consolidated Net Income (or if such Adjusted
     Consolidated Net Income is a loss, minus 100% of such loss) of the Company
     and its Subsidiaries for the period from the first day of the first quarter
     ended subsequent to the Closing Date and through the last day of the most
     recently completed quarter immediately preceding the quarter in which the
     Restricted Payment occurs, calculated on a cumulative basis as if such
     period were a single accounting period; (B) the aggregate net proceeds
     received by the Company after the Closing Date (including the fair market
     value of non-cash proceeds as determined in good faith by the Board of
     Directors as evidenced by a Board Resolution) from any Person other than a
     Subsidiary, as a result of the issuance of (or contribution to capital on)
     Capital Stock of the Company (other than any Redeemable Stock) or warrants,
     rights or options to acquire Capital Stock (other than any Redeemable
     Stock); (C) the aggregate net proceeds received by the Company after the
     Closing Date from any Person other than a Subsidiary as a result of the
     issuance of Capital Stock (other than Redeemable Stock) upon conversion or
     exchange of Indebtedness or upon exercise of options, warrants or other
     rights to acquire such Capital Stock and (D) $25,000,000. For purposes of
     any calculation that is required to be made in respect of, or after, the
     declaration of a dividend by the Company, such dividend shall be deemed to
     be paid at the date of declaration and shall be included in determining the
     aggregate amount of Restricted Payments.
 
          For the purposes of this Section 4.13, the net proceeds from the
     issuance of shares of Capital Stock of the Company upon conversion of debt
     securities shall be deemed to be an amount equal to the net book value of
     such debt securities (plus the additional amount required to be paid upon
     such conversion, if any), less any cash payment on account of fractional
     shares; the "net book value" of a security shall be the net amount received
     by the Company on the issuance of such security, as adjusted on the books
     of the Company to the date of conversion.
 
          (b) Notwithstanding the foregoing, if no Default or Event of Default
     shall have occurred or be continuing at the time or as a result thereof,
     the provisions of this Section 4.13 shall not prohibit (i) the
 
                                       19
<PAGE>   26
 
     payment of any dividend in respect of the Company's Capital Stock within 60
     days after the date of declaration thereof, if at such date of declaration
     such payment complied with the provisions hereof; (ii) the purchase,
     redemption or other acquisition or retirement for value of any shares of
     the Company's Capital Stock or the prepayment of any indebtedness of the
     Company which is subordinated in right of payment to the Securities or
     which matures after the maturity date of the Securities by any exchange
     for, or out of and to the extent the Company has received cash proceeds
     from the substantially concurrent sale or issuance (other than to a
     Subsidiary) of, shares of Capital Stock (other than any Redeemable Stock)
     of the Company or warrants, rights or options to acquire Capital Stock
     (other than any Redeemable Stock); or (iii) the purchase or redemption of
     shares of Capital Stock of the Company (including options on any such
     shares or related stock appreciation rights or similar securities) held by
     officers or employees of the Company or its Subsidiaries (or their estates
     or beneficiaries under their estates) upon death, disability, retirement,
     termination of employment of any such Person pursuant to the terms of any
     Plan or any other agreement under which such shares of stock or related
     rights were issued; provided that the aggregate amount of such purchases or
     redemptions of such Capital Stock shall not exceed $3,000,000 in any one
     fiscal year of the Company. For purposes of determining the aggregate
     amount of Restricted Payments permitted under clause (y) of Section
     4.13(a), all amounts expended pursuant to clauses (i) (to the extent deemed
     to have been paid and already included in determining the aggregate amount
     of Restricted Payments pursuant to clause (y) of Section 4.13(a)), (ii) and
     (iii) of this paragraph shall be excluded.
 
          Prior to making any Restricted Payment under this Section, the Company
     shall deliver to the Trustee an Officers' Certificate setting forth the
     computation by which the amount available for Restricted Payments was
     determined. The Trustee shall have no duty or responsibility to determine
     the accuracy or correctness of this computation or that the provisions of
     this Section have been satisfied and shall be fully protected in relying on
     such Officers' Certificate.
 
     SECTION 4.14  Limitation on Transactions with Affiliates.
 
   
          (a) Neither the Company nor any Subsidiary of the Company shall,
     directly or indirectly (i) sell, lease, transfer or otherwise dispose of
     any of its properties or assets, or issue securities to, (ii) purchase any
     property, assets or securities from, (iii) make any Investment in, or (iv)
     enter into or suffer to exist any contract or agreement with or for the
     benefit of, an Affiliate or holder of 5% or more of any class of Capital
     Stock (and any Affiliate of such holder) of the Company (an "Affiliate
     Transaction"), other than (x) Affiliate Transactions permitted under
     Section 4.14(b) and (y) Affiliate Transactions (including lease
     transactions) which are on fair and reasonable terms no less favorable to
     the Company or such Subsidiary, as the case may be, than those as might
     reasonably have been obtainable at such time from an unaffiliated party;
     provided that if an Affiliate Transaction or series of related Affiliate
     Transactions involves or has a value in excess of $10,000,000, the Company
     or such Subsidiary, as the case may be, shall not enter into such Affiliate
     Transaction or series of related Affiliate Transactions unless a majority
     of the disinterested members of the Board of Directors of the Company or
     such Subsidiary shall reasonably and in good faith determine that such
     Affiliate Transaction is fair to the Company or such Subsidiary, as the
     case may be, or is on terms no less favorable to the Company or such
     Subsidiary, as the case may be, than those as might reasonably have been
     obtainable at such time from an unaffiliated party.
    
 
          (b) The provisions of Section 4.14(a) shall not apply to (i) any
     agreement as in effect as of the Closing Date, or any amendment thereto so
     long as any such amendment is not disadvantageous to the Holders in any
     material respect or any transaction contemplated thereby (including
     pursuant to any amendment thereto); (ii) any transaction between the
     Company and any Wholly Owned Subsidiary or between Wholly Owned
     Subsidiaries, provided such transactions are not otherwise prohibited by
     this Indenture; (iii) reasonable and customary fees and compensation paid
     to, and indemnity provided on behalf of, officers, directors, employees or
     consultants of the Company or any Subsidiary, as determined by the Board of
     Directors of the Company or any Subsidiary or the senior management thereof
     in good faith; (iv) any Restricted Payments not prohibited by Section 4.13;
     (v) any payments or other transactions pursuant to any tax sharing
     agreement between the Company and any other Person with which the Company
     is required or permitted to file a consolidated tax return or with which
     the Company
 
                                       20
<PAGE>   27
 
     is or could be part of a consolidated group for tax purposes; and (vi)
     transactions with Continental Airlines, Inc., Mesa Airlines, Inc. and their
     respective Affiliates as contemplated by the Alliance Agreements.
 
     SECTION 4.15  Limitation on Asset Sales.  Subject to the following
paragraphs of this Section, in the event and to the extent that on any date
after the Closing Date the Company and its Subsidiaries shall receive Net Cash
Proceeds from one or more Asset Sales (other than Asset Sales by the Company or
any Subsidiary to the Company or another Subsidiary), then the Company shall, or
shall cause such Subsidiary to, within 12 months after such date apply an amount
equal to such Net Cash Proceeds (A) to repay Indebtedness of the Company or
Indebtedness of any Subsidiary, in each case owing to a Person other than the
Company or any of its Subsidiaries, and/or (B) as an Investment (or enter into a
definitive agreement committing to so invest within 12 months after the date of
such agreement), in property or assets of a nature or type or that are used in a
business (or in a Person having property and assets of a nature or type, or
engaged in a business) similar or related to the nature or type of the property
and assets of, or the business of, the Company and its Subsidiaries existing on
the date thereof (as determined in good faith by the Board of Directors of the
Company or such Subsidiary, as the case may be, whose determination shall be
conclusive and evidenced by a Board Resolution). The amount of such Net Cash
Proceeds required to be applied (or to be committed to be applied) during such
12-month period as set forth in clause (A) or (B) of the preceding sentence
shall constitute "Excess Proceeds."
 
     If on the first Business Day following any 12-month period referred to in
the preceding paragraph, the aggregate amount of Excess Proceeds from all Asset
Sales, not previously applied as provided in clause (A) or (B) of the preceding
paragraph, exceeds $15,000,000, the Company, within 10 Business Days after the
end of any such 12-month period, make an offer to purchase on a pro rata basis
from all Holders (an "Excess Proceeds Offer"), and shall purchase from Holders
accepting such Excess Proceeds Offer, the maximum principal amount (expressed as
an integral multiple of $1,000) of Securities that may be purchased from funds
in an amount equal to all such outstanding Excess Proceeds at a purchase price
equal to 100% of the principal amount of the Securities so purchased, plus
accrued and unpaid interest thereon (if any) to the date of purchase ("Excess
Proceeds Payment"). Upon completion of an Excess Proceeds Offer (or upon
termination of such offer if no repurchases are required), the amount of such
Excess Proceeds relating thereto shall be equal to zero.
 
     The Company shall commence an Excess Proceeds Offer by causing the Trustee
to mail a notice to each Holder stating: (i) that the Excess Proceeds Offer is
being made pursuant to this Section 4.15 and that all Securities validly
tendered will be accepted for purchase; provided, however, that if the aggregate
purchase price of Securities tendered in an Excess Proceeds Offer (including
accrued interest to the date of purchase) exceeds the aggregate amount of the
Excess Proceeds required to be applied in such Excess Proceeds Offer, the
Company shall select the Securities to be purchased on a pro rata basis (with
such adjustments as may be deemed appropriate by the Company so that only
Securities in denominations of $1,000 or integral multiples thereof shall be
purchased); (ii) the purchase price (including the amount of accrued interest)
and the purchase date (which shall be a Business Day no earlier than 30 days nor
later than 60 days from the date such notice is mailed) (the "Excess Proceeds
Purchase Date"); (iii) that any Security not tendered will continue to accrue
interest pursuant to its terms; (iv) that, unless the Company defaults in the
purchase of such Security on the Excess Proceeds Purchase Date, any Security
accepted for purchase pursuant to the Excess Proceeds Offer shall cease to
accrue interest after the Excess Proceeds Purchase Date; (v) that Holders
electing to have a Security purchased pursuant to the Excess Proceeds Offer will
be required to surrender the Security, together with the form entitled "Option
of the Holder to Elect Purchase" on the reverse side of the Security completed,
to the Paying Agent at the address specified in the notice prior to the close of
business on the Business Day immediately preceding the Excess Proceeds Purchase
Date; (vi) that each Holder will be entitled to withdraw its election (in whole
but not in part) if the Paying Agent receives, not later than the close of
business on the third Business Day immediately preceding the Excess Proceeds
Purchase Date, a telegram, telex, facsimile transmission or letter setting forth
the name of such Holder, the principal amount of Securities delivered for
purchase and a statement that such Holder is withdrawing its election to have
such Securities purchased; and (vii) that Holders whose Securities are being
purchased only
 
                                       21
<PAGE>   28
 
in part will be issued new Securities equal in aggregate principal amount to the
unpurchased portion of the Securities surrendered.
 
     On the Excess Proceeds Purchase Date, the Company shall: (i) accept for
purchase on a pro rata basis Securities or portions thereof tendered pursuant to
the Excess Proceeds Offer; (ii) deposit with the Paying Agent money sufficient
to pay the purchase price of all Securities or portions thereof so accepted; and
(iii) deliver, or cause to be delivered, to the Trustee all Securities or
portions thereof so accepted together with an Officers' Certificate specifying
the Securities or portions thereof accepted for purchase by the Company. The
Paying Agent shall promptly mail to the Holders of Securities so accepted
payment in an amount equal to the purchase price, and the Company shall execute
and the Trustee shall promptly authenticate and mail to each such Holders a new
Security equal in principal amount to any unpurchased portion of the Security
surrendered; provided that each Security purchased and each new Security
delivered shall be in a principal amount of $1,000 or an integral multiple
thereof. The Company will publicly announce the results of the Excess Proceeds
Offer as soon as practicable after the Excess Proceeds Purchase Date. For
purposes of this Section 4.15, the Trustee shall act as the Paying Agent.
 
     Notwithstanding the foregoing:
 
          (i) to the extent that any or all of the Net Cash Proceeds of any
     Asset Sale are prohibited or delayed by applicable local law from being
     repatriated to the United States of America, the portion of such Net Cash
     Proceeds so affected will not be required to be applied pursuant to this
     Section 4.14 but may be retained for so long, but only for so long, as the
     applicable local law will not permit repatriation to the United States of
     America (the Company hereby agrees to promptly take all reasonable actions
     required by the applicable local law to permit such repatriation) and once
     such repatriation of any such affected Net Cash Proceeds is permitted under
     the applicable local law, such repatriation will be immediately effected
     and such repatriated Net Cash Proceeds will be applied in the manner set
     forth in this Section 4.15 as if such Asset Sale had occurred on the date
     of repatriation; and
 
          (ii) to the extent that the Board of Directors of the Company has
     determined in good faith that repatriation of any or all of the Net Cash
     Proceeds would have an adverse tax consequence to the Company, the Net Cash
     Proceeds so affected may be retained outside the United States of America
     for so long as such adverse tax consequences would continue.
 
     The Company will comply with Rule 14e-1 under the Securities Exchange Act
of 1934, as amended, and any other securities laws and regulations thereunder to
the extent such laws and regulations are applicable, in the event that such
Excess Proceeds are received by the Company as contemplated by this Section 4.15
and the Company is required to repurchase Securities as described above.
 
   
     SECTION 4.16  Limitation on Payment Restrictions Affecting
Subsidiaries.  The Company shall not, and shall not permit any Subsidiary to,
create or otherwise cause or suffer to exist or become effective any Payment
Restriction or consensual encumbrance with respect to any Subsidiary thereof to
(a) pay dividends or make any other distributions on such Subsidiary's Capital
Stock; (b) make any loans or advances to the Company or any other Subsidiary; or
(c) transfer any of its property or assets to the Company or any other
Subsidiary except (i) restrictions imposed by applicable law; (ii) any
restrictions existing under this Indenture; and (iii) encumbrances or
restrictions contained in any agreement or instrument (A) relating to any
property acquired or leased by the Company or any of its Subsidiaries after the
Closing Date, provided that such encumbrance or restriction relates only the
property which is acquired or leased; (B) relating to any Indebtedness of any
Subsidiary at the date of acquisition of such Subsidiary by the Company or any
Subsidiary of the Company, provided that such Indebtedness was not incurred in
connection with, or in contemplation of, such acquisition (the Company being
entitled to rely upon a certificate of such Subsidiary as to whether such
Indebtedness was incurred in contemplation thereof); (C) arising pursuant to an
agreement effecting a refinancing of Indebtedness issued pursuant to an
agreement referred to in the foregoing clauses (A) and (B), so long as the
encumbrances and restrictions contained in any such refinancing agreement are no
more restrictive than the encumbrances and restrictions contained in such
agreements; (D) which constitute customary provisions restricting subletting or
assignment of any lease of the Company or any Subsidiary or provisions in
agreements that restrict the assignment of such agreement or any rights
thereunder;
    
 
                                       22
<PAGE>   29
 
and (E) which constitute restrictions on the sale or other disposition of any
property securing Indebtedness as a result of a lien on such property.
 
   
     SECTION 4.17  [Intentionally Omitted].
    
 
   
     SECTION 4.18  Limitation on Investments.  The Company shall not, and shall

consisting of non-cash proceeds from Asset Sales as contemplated by Section 4.15
of this Indenture; (ii) Investments consisting of Cash Equivalents; (iii)
accounts receivable if credited or acquired in the ordinary course of business

Company, in an aggregate amount not exceeding $5,000,000 in any fiscal year of
the Company; (viii) Investments made by way of any endorsement of negotiable
instruments received by the Company or any Subsidiary in the ordinary course of
its business and presented by it to any bank for collection or deposit; (ix)
stock, obligations or securities received in settlement of debts created in the
ordinary course of business owing to the company or any Subsidiary; (x)
Investments by the Company in any Subsidiary for the purpose of receivables
financing; and (xi) in addition to any other permitted investments, any other

any time].
    
 
   
     SECTION 4.19  Waiver of Stay, Extension or Usury Laws.  The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law or any usury law or other law
that would prohibit or forgive the Company from paying all or any portion of the
principal of, premium, if any, or interest on the Securities as contemplated
herein, wherever enacted, now or at any time hereafter in force, or that may
affect the covenants or the performance of this Indenture; and (to the extent
that it may lawfully do so) the Company hereby expressly waives all benefit or
advantage of any such law and covenants that it will not hinder, delay or impede
the execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law had been enacted.

Trustee may reasonably require of the names and addresses of the Holders of the
Securities pursuant to Section 312 of the TIA:
 
          (a) semi-annually and not more than 15 days after each record date for

     more than 15 days prior to the time such information is furnished.
 
     SECTION 5.2  Disclosure of Names and Addresses of Securityholders.  Each
and every Holder of Securities, by receiving and holding the same, agrees with
the Company and the Trustee that neither the Company nor the Trustee nor any
agent of the Company or the Trustee shall be held accountable by reason of the
disclosure of any such information as to the names and addresses of the Holders
of Securities in accordance with Section 312 of the TIA, regardless of the

                 CONSOLIDATION, MERGER, CONVEYANCE OR TRANSFER
 
     SECTION 6.1  Merger or Consolidation.  The Company shall not consolidate
with or merge into any other corporation or convey, lease or transfer its
properties and assets substantially as an entirety to any Person, unless:
 
          (a) the corporation formed by such consolidation or into which the
     Company is merged or the Person that acquires by conveyance, lease or
     transfer the properties and assets of the Company substantially as an
     entirety shall be a corporation organized and existing under the laws of
     the United States of America or any State or the District of Columbia, and
     shall expressly assume, by an indenture supplemental hereto, executed and
     delivered to the Trustee, in form satisfactory to the Trustee, the
     Company's obligation for the due and punctual payment of the principal of
     and interest on all the Securities according to their tenor and the
     performance of every covenant of this Indenture on the part of the Company
     to be performed or observed;
 
   
          (b) immediately before and after giving effect to such transaction, no
     Event of Default, and no event that, after notice or lapse of time, or
     both, would become an Event of Default, shall have happened and be
     continuing; and
    
 
   
          (c) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel each stating that such consolidation, merger,
     conveyance, lease or transfer and such supplemental indenture comply with
     this Article and that all conditions precedent herein provided for relating
     to such transaction have been complied with.
    
 
   
     This Section shall only apply to a merger or consolidation in which the
Company is not the surviving corporation and to conveyances, leases, and
transfers by the Company, as transferee or lessor.
    
 
     SECTION 6.2  Successor Corporation Substituted.  Upon any consolidation or
merger by the Company with or into any other corporation, or any conveyance or
transfer by the Company of its properties and assets substantially as an
entirety to any Person, in accordance with Section 6.1, the successor
corporation formed by such consolidation or into which the Company is merged or
to which such conveyance or transfer is made shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor corporation had been
named as the Company and in the event of any such conveyance or transfer, the
Company, except in the event of a conveyance by way of lease, shall be
discharged from all obligations and covenants under this Indenture and the
Securities and may be dissolved and liquidated. Such successor corporation may
cause to be signed, and may issue either in its own name or in the name of the
Company prior to such succession, any or all of the Securities issuable
hereunder that theretofore shall not have been signed by the Company or and
delivered to the Trustee; and, upon the order of such successor corporation,
instead of the Company and subject to all the terms, conditions and limitations
in this Indenture prescribed, the Trustee shall authenticate and shall deliver
any Securities that previously shall have been signed and delivered by the
officers of the Company to the Trustee for authentication, and any Securities
that such successor corporation thereafter shall, cause to be signed and
delivered to the Trustee for that purpose. All the Securities so issued shall in
all respects have the same legal rank and benefit under this Indenture as the
Securities theretofore or thereafter issued in accordance with the terms of this
Indenture as though all of such Securities had been issued at the date of the
execution hereof.
 
     In case of any such consolidation, merger, conveyance or transfer, such
changes in phrasing and form (but not in substance) may be made in the
Securities that may be endorsed thereon, as the case may be, thereafter to be
delivered as may be appropriate.

                            REMEDIES OF THE TRUSTEE
                    AND SECURITYHOLDERS ON EVENT OF DEFAULT
 
     SECTION 7.1  Event of Default Defined; Acceleration of Maturity; Waiver of
Default.  "Event of Default", with respect to the Securities, means any one of
the following events that shall have occurred and be continuing (whatever the
reason for such Event of Default and whether it shall be voluntary or
involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body):
 
          (a) default in the payment of the principal of or premium (if any) on
     any Security when the same becomes due and payable at maturity, upon
     acceleration, redemption or otherwise;
 
          (b) default in the payment of interest on any Security when the same
     becomes due and payable, and such default continues for a period of 30
     days;
 
          (c) the Company defaults in the performance of or breaches any other
     covenant or agreement of the Company in this Indenture or under the
     Securities and such default or breach continues for a period of 30
     consecutive days after the date on which written notice specifying such
     failure, stating that such notice is a "Notice of Default" under the
     Indenture and demanding that the Company remedy the same, shall have been
     given by registered or certified mail, return receipt requested, to the
     Company by the Trustee or to the Company and the Trustee by the Holders of
     25% or more in aggregate principal amount of the Securities Outstanding;
 
          (d) there occurs with respect to any issue or issues of Indebtedness
     of the Company and/or one or more Subsidiaries having an outstanding
     principal amount of $10 million or more in the aggregate for all such
     issues of all such Persons, whether such Indebtedness now exists or shall
     hereafter be created, an event of default that has caused the holder
     thereof to declare such Indebtedness to be due and payable prior to its
     Stated Maturity and such Indebtedness has not been discharged in full or
     such acceleration has not been rescinded or annulled within 30 days of such
     acceleration;
 
          (e) any final judgment or order (not covered by insurance) for the
     payment of money in excess of $10 million in the aggregate for all such
     final judgments or orders against all such Persons (treating any
     deductibles, self-insurance or retention as not so covered) shall be
     rendered against the Company or any Subsidiary and shall not be discharged,
     and there shall be any period of 60 consecutive days following entry of the
     final judgment or order that causes the aggregate amount for all such final
     judgments or orders outstanding against all such Persons to exceed $10
     million during which a stay of enforcement of such final judgment or order,
     by reason of a pending appeal or otherwise, shall not be in effect;
 
   
          (f) a court having jurisdiction in the premises enters a decree or
     order for (i) relief in respect of the Company or any Material Subsidiary
     in an involuntary case under any applicable bankruptcy, insolvency or other
     similar law now or hereafter in effect, (ii) appointment of a receiver,
     liquidator, assignee, custodian, trustee, sequestrator or similar official
     of the Company or any Material Subsidiary or for all or substantially all
     of the property and assets of the Company or any Material Subsidiary or
     (iii) the winding up or liquidation of the affairs of the Company or any
     Material Subsidiary and, in each case, such decree or order shall remain
     unstayed and in effect for a period of 60 consecutive days;
    
 
   
          (g) the Company or any Material Subsidiary (i) commences a voluntary

     the Company or any Material Subsidiary or (iii) effects any general
     assignment for the benefit of creditors of the Company or any Material
     Subsidiary;
    
 
          (h) the Company and/or one or more Subsidiaries fail to make at the
     final (but not any interim) fixed maturity of one or more issues of
     Indebtedness a principal payment or principal payments
 
                                       25
<PAGE>   32
 
     aggregating more than $10 million and all such defaulted payments shall not
     have been made, waived or extended within 30 days of the payment default
     that caused the aggregate amount of such defaulted payments to exceed $10
     million; or
 
          (i) any of the Applicable Documents shall cease, for any reason, to be
     in full force and effect in any material respect, except as a result of an
     amendment, waiver or termination thereof as contemplated or permitted
     therein.
 
     If an Event of Default (other than an Event of Default specified in clause
(f) or (g) above that occurs with respect to the Company) occurs and is
continuing, the Trustee or the Holders of at least 25% of the aggregate
principal amount of the Securities then Outstanding, by written notice to the
Company (and to the Trustee if such notice is given by the Holders (the
"Acceleration Notice" )), may, and the Trustee at the request of the Holders
shall, declare the entire unpaid principal, premium (if any) and accrued
interest on the Securities to be immediately due and payable as specified below.
Upon a declaration of acceleration, such principal, premium (if any) and accrued
interest shall be immediately due and payable. In the event of a declaration of
acceleration because an Event of Default set forth in clause (d) above has
occurred and is continuing, such declaration of acceleration shall be
automatically rescinded and annulled if the event of default triggering such
Event of Default shall be remedied, cured by the Company or waived by the
holders of the relevant Indebtedness within 30 days after the occurrence of the
Event of Default with respect thereto and the Company has delivered an Officer's
Certificate as to such effect. If an Event of Default specified in clause (f) or
(g) above occurs with respect to the Company, all unpaid principal of, premium
(if any) and accrued interest on the Securities then outstanding shall ipso
facto become and be immediately due and payable without declaration or other act
on the part of the Trustee or any Holder.
 
     The Holders of at least a majority in principal amount of the outstanding
Securities, by written notice to the Company and the Trustee, may waive all past
defaults and rescind and annul a declaration of acceleration and its
consequences if (i) all existing Events of Default, other than the non-payment
of the principal of, premium, if any, and interest on Securities that have
become due solely by such declaration of acceleration, have been cured or waived
and (ii) the rescission would not conflict with any judgment or decree of a
court of competent jurisdiction.
 
     Upon receipt by the Trustee of any Notice of Default pursuant to this
Section 7.1 with respect to Securities all or part of which are represented by a
Global Security, a record date shall be established for determining Holders of
Outstanding Securities entitled to join in such Notice of Default, which record
date shall be at the close of business on the day the Trustee receives such
Notice of Default. The Holders on such record date, or their duly designated
proxies, and only such Persons, shall be entitled to join in such Notice of
Default, whether or not such Holders remain Holders after such record date;
provided, that unless Holders of at least 25% in principal amount of the
Outstanding Securities, or their proxies, shall have joined in such Notice of
Default prior to the day which is 90 days after such record date, such Notice of
Default shall automatically and without further action by any Holder be
cancelled and of no further effect. Nothing in this paragraph shall prevent a
Holder, or a proxy of a Holder, from giving, after expiration of such 90-day
period, a new Notice of Default identical to a Notice of Default which has been
cancelled pursuant to the proviso to the preceding sentence, in which event a
new record date shall be established pursuant to the provisions of this Section
7.1.
 
     Upon receipt by the Trustee of any Acceleration Notice or any rescission
and annulment thereof, with respect to Securities all or part of which are
represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Securities entitled to join in such notice,
which record date shall be at the close of business on the day the Trustee
receives such notice. The Holders on such record date, or their duly designated
proxies, and only such Persons, shall be entitled to join in such notice,
whether or not such Holders remain Holders after such record date; provided,
that unless such declaration of acceleration, or rescission and annulment, as
the case may be, shall have become effective by virtue of the requisite
percentage having joined in such notice prior to the day which is 90 days after
such record date, such notice of declaration of acceleration or rescission and
annulment, as the case may be, shall automatically and without further action by
any Holder be cancelled and of no further effect. Nothing in this paragraph
shall
 
                                       26
<PAGE>   33
 
prevent a Holder, or a proxy of a Holder, from giving, after expiration of such
90-day period, a new written notice of declaration of acceleration, or
rescission and annulment thereof, as the case may be, that is identical to a
written notice which has been cancelled pursuant to the proviso to the preceding
sentence, in which event a new record date shall be established pursuant to the
provisions of this Section 7.1.
 
     SECTION 7.2  Collection of Indebtedness by Trustee; Trustee May Prove
Debt.  The Company covenants that (a) in case default shall be made in the
payment of any installment of interest on any of the Securities when such
interest shall have become due and payable, and such default shall have
continued for a period of 30 days or (b) in case default shall be made in the
payment of all or any part of the principal of any of the Securities when the
same shall have become due and payable, whether upon maturity of the Securities
or upon any redemption or by declaration or otherwise, then upon demand of the
Trustee, the Company will pay to the Trustee for the benefit of the Holders of
the Securities the whole amount that then shall have become due and payable an
all Securities for principal or interest, as the case may be (with interest to
the date of such payment upon the overdue principal and, to the extent that
payment of such interest is enforceable under applicable law, on overdue
installments of interest at the same rate as the rate of interest specified in
the Securities); and in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, including reasonable
compensation to the Trustee and each predecessor Trustee, their respective
agents, attorneys and counsel, and any expenses and liabilities incurred, and
all advances made by the Trustee and each predecessor Trustee except as a result
of its negligence or bad faith.
 
     Until such demand is made by the Trustee, the Company may pay the principal
of and interest on the Securities to the registered Holders, whether or not the
Securities are overdue.
 
     In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any action or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceedings to judgment or final decree, and may enforce any such
judgment or final decree against the Company or other obligor upon the
Securities and collect in the manner provided by law out of the property of the
Company or other obligor upon the Securities, wherever situated the monies
adjudged or decreed to be payable.
 
     In case there shall be pending proceedings relative to the Company or any
other obligor upon the Securities under Title 11 of the United States Code or
any other applicable Federal or state bankruptcy, insolvency or other similar
law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Company or the property of the Company or such other
obligor, or in case of any other judicial proceedings relative to the Company or
other obligor upon the Securities, or to the creditors or property of the
Company or such other obligor, the Trustee, irrespective of whether the
principal of the Securities shall then be due and payable as therein expressed
or by declaration or otherwise and irrespective of whether the Trustee will have
made any demand pursuant to the provisions of this Section, shall be entitled
and empowered, by intervention in such proceedings or otherwise:
 
          (a) to file and prove a claim or claims for the whole amount of
     principal and interest owing and unpaid in respect of the Securities and to
     file such other papers or documents as may be necessary or advisable in
     order to have the claims of the Trustee (including any claim for reasonable
     compensation to the Trustee and each predecessor Trustee and their
     respective agents, attorneys and counsel, and for reimbursement of all
     expenses and liabilities incurred, and all advances made, by the Trustee
     and each predecessor Trustee, except as a result of negligence or bad
     faith) and of the Securityholders allowed in any judicial proceedings
     relative to the Company or other obligor upon the Securities, or to the
     creditors or property of the Company or such other obligor,
 
          (b) unless prohibited by applicable law and regulations, to vote on
     behalf of the Holders of the Securities in any election of a trustee or a
     standby trustee in arrangement, reorganization, liquidation or other
     bankruptcy or insolvency proceedings or person performing similar functions
     in comparable proceedings, and
 
                                       27
<PAGE>   34
 
          (c) to collect and receive any monies or other property payable or
     deliverable on any such claims, and to distribute all amounts received with
     respect to the claims of the Securityholders and of the Trustee on their
     behalf; and any trustee, receiver, or liquidator, custodian or other
     similar official is hereby authorized by each of the Securityholders to
     make payments to the Trustee, and, in the event that the Trustee shall
     consent to the making of payments directly to the Securityholders, to pay
     to the Trustee such amounts as shall be sufficient to cover reasonable
     compensation to the Trustee, each predecessor Trustee and their respective
     agents, attorneys and counsel, and all other expenses and liabilities
     incurred, and all advances made, by the Trustee and each predecessor
     Trustee except as a result of negligence or bad faith.
 
     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or vote for or accept or adopt on behalf of any
Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Securityholder in
any such proceeding except, as aforesaid, to vote for the election of a trustee
in bankruptcy or similar person.
 
     All rights of action and of asserting claims under this Indenture, or under
any of the Securities may be enforced by the Trustee without the possession of
any of the Securities or the production thereof on any trial or other
proceedings relative thereto, and any such action or proceedings instituted by
the Trustee shall be brought in its own name as trustee of an express trust, and
any recovery of judgment, subject to the payment of the expenses, disbursements
and compensation of the Trustee, each predecessor Trustee and their respective
agents and attorneys, shall be for the ratable benefit of the Holders of the
Securities in respect of which such judgment has been recovered.
 
     In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the Holders
of the Securities in respect of which such action was taken, and it shall not be
necessary to make any Holders of such Securities parties to any such
proceedings.
 
     SECTION 7.3  Application of Proceeds.  Any monies collected by the Trustee
pursuant to this Article Seven in respect of the Securities shall be applied in
the following order at the date or dates fixed by the Trustee and, in the case
of the distribution of such monies on account of principal or interest, upon
presentation of the several Securities in respect of which monies have been
collected and stamping (or otherwise noting) thereon the payment, or issuing
Securities in reduced principal amounts in exchange for the presented Securities
if only partially paid, or upon surrender thereof if fully paid:
 
          FIRST: To the payment of amounts due the Trustee or any predecessor
     Trustee under Section 8.6;
 
          SECOND: In case the principal of the Securities shall not have become
     and be then due and payable, to the payment of interest on the Securities
     in default in the order of the maturity of the installments of such
     interest, with interest (to the extent that such interest has been
     collected by the Trustee) upon the overdue installments of interest at the
     same rate as the rate of interest specified in the Securities, such
     payments to be made ratably to the persons entitled thereto, without
     discrimination or preference;
 
          THIRD: In case the principal of the Securities shall have become and
     shall be then due and payable, to the payment of the whole amount then
     owing and unpaid upon all the Securities for principal and interest, with
     interest upon the overdue principal, and (to the extent that such interest
     has been collected by the Trustee) upon overdue installments of interest at
     the same rate as the rate of interest specified in the Securities and in
     case such monies shall be insufficient to pay in full the whole amount so
     due and unpaid upon the Securities, then to the payment of such principal
     and interest without preference or priority of principal over interest or
     of interest over principal, or of any installment of interest over any
     other installment of interest, or of any Security over any other Security,
     ratably to the aggregate of such principal and accrued and unpaid interest;
     and
 
          FOURTH: To the payment of the remainder, if any, to the Company or any
     other person lawfully entitled thereto.
 
                                       28
<PAGE>   35
 
     SECTION 7.4  Suits for Enforcement.  In case an Event of Default has
occurred, has not been waived and is continuing, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.
 
     SECTION 7.5  Restoration of Rights on Abandonment of Proceedings.  In case
the Trustee shall have proceeded to enforce any right under this Indenture and
such proceedings shall have been discontinued or abandoned for any reason, or
shall have been determined adversely to the Trustee, then and in every such case
the Company and the Trustee shall be restored respectively to their former
positions and rights hereunder, and all rights, remedies and powers of the
Company, the Trustee and the Securityholders shall continue as though no such
proceedings had been taken.
 
     SECTION 7.6  Limitations on Suits by Securityholders.  A Holder of
Securities may not pursue any remedy with respect to this Indenture or the
Securities unless; (i) such Holder gives to the Trustee written notice of a
continuing Event of Default; (ii) the Holders of at least 25% in aggregate
principal amount of outstanding Securities make a written request to the Trustee
to pursue the remedy; (iii) such Holder or Holders offer to the Trustee
indemnity satisfactory to the Trustee against any costs, liability or expense;
(iv) the Trustee does not comply with the request within 60 days after receipt
of the request and the offer of indemnity; and (v) during such 60-day period,
the Holders of a majority in aggregate principal amount of the outstanding
Securities do not give the Trustee a direction that is inconsistent with the
request.
 
     For purposes of this Section 7.6, the Trustee shall comply with Section
316(a) of the TIA in making any determination of whether the Holders of the
required aggregate principal amount of outstanding Securities have concurred in
any request or direction of the Trustee to pursue any remedy available to the
Trustee or the Holders with respect to this Indenture or the Securities or
otherwise under the law.
 
     A Holder of Securities may not use this Indenture to prejudice the rights
of another Holder or to obtain a preference or priority over such other Holder.
 
     SECTION 7.7  Unconditional Right of Securityholders to Institute Certain
Suits.  Notwithstanding any other provision in this Indenture and any provision
of any Security, the right of any Holder of any Security to receive payment of
the principal of, premium (if any) and interest on such Security on or after the
respective due dates expressed in such Security, or to institute suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.
 
     SECTION 7.8  Powers and Remedies Cumulative; Delay or Omission Not Waiver
of Default.  Except as provided in Section 7.6, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.
 
     No delay or omission of the Trustee or of any Holder to exercise any right
or power accruing upon any Event of Default occurring and continuing as
aforesaid shall impair any such right or power or shall be construed to be a
waiver of any such Event of Default or an acquiescence therein; and, subject to
Section 7.6, every power and remedy given by this Indenture or by law to the
Trustee or to the Holders may be exercised from time to time, and as often as
shall be deemed expedient, by the Trustee or by the Holders.
 
     SECTION 7.9  Control by Holders of Securities.  The Holders of a majority
in aggregate principal amount of the Securities at the time outstanding shall
have the right to direct the time, method, and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred on the Trustee with respect to the Securities by this Indenture;
provided, that such direction shall not be otherwise than in accordance with law
and the provisions of this Indenture; and provided, further, that
 
                                       29
<PAGE>   36
 
(subject to the provisions of Section 8.1) the Trustee shall have the right to
decline to follow any such direction if the Trustee, being advised by counsel,
shall determine that the action or proceeding so directed may not lawfully be
taken or if the Trustee in good faith by its board of directors, the executive
committee, or a trust committee of directors or Responsible Officers of the
Trustee shall determine that the action or proceedings so directed would involve
the Trustee in personal liability or if the Trustee in good faith shall so
determine that the actions or forbearances specified in or pursuant to such
direction would be unduly prejudicial to the interests of Holders not joining in
the giving of said direction. It being understood that (subject to Section 8.1)
the Trustee shall have no duty to ascertain whether or not such actions or
forbearances are unduly prejudicial to such Holders.
 
     Nothing in this Indenture shall impair the right of the Trustee in its
discretion to take any action deemed proper by the Trustee and that is not
inconsistent with such direction or directions by the Holders.
 
     Upon receipt by the Trustee of any written notice directing the time,
method or place of conducting any such proceeding or exercising any such trust
or power, with respect to Securities all or part of which are represented by a
Global Security, a record date shall be established for determining Holders of
Outstanding Securities entitled to join in such notice, which record date shall
be at the close of business on the day the Trustee receives such notice. The
Holders on such record date, or their duly designated proxies, and only such
Persons, shall be entitled to join in such notice, whether or not such Holders
remain Holders after such record date; provided, that unless the Holders of a
majority in principal amount of the Outstanding Securities shall have joined in
such notice prior to the day which is 90 days after such record date, such
notice shall automatically and without further action by any Holder be cancelled
and of no further effect. Nothing in this paragraph shall prevent a Holder, or a
proxy of a Holder, from giving, after expiration of such 90-day period, a new
notice identical to a notice which has been cancelled pursuant to the proviso to
the preceding sentence, in which event a new record date shall be established
pursuant to the provisions of this Section 7.9.
 
     SECTION 7.10  Waiver of Past Defaults.  Subject to Sections 7.1 and 7.7,
the Holders of at least a majority in principal amount of the outstanding
Securities, by notice to the Trustee, may waive an existing Event of Default and
its consequences, except a default in the payment of principal of or interest on
any Security as specified in clause (a) or (b) of Section 7.1.
 
     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Persons entitled to waive any past default hereunder.
If a record date is fixed, the Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to waive any
default hereunder, whether or not such Holders remain Holders after such record
date; provided, that unless such majority in principal amount shall have waived
such default prior to the date which is 90 days after such record date, any such
waiver previously given shall automatically and without further action by any
Holder be cancelled and of no further effect.
 
     Upon any such waiver, such Default shall cease to exist and be deemed to
have been cured and not to have occurred, and any Event of Default arising
therefrom shall be deemed to have been cured, and not to have occurred for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default at Event of Default or impair any right consequent thereon.
 
     SECTION 7.11  Trustees to Give Notice of Default, But May Withhold in
Certain Circumstances.  The Trustee shall, within ninety days after the
occurrence of a Default with respect to the Securities, give notice of all
Defaults known to the Trustee to all Holders of Securities in the manner and to
the extent provided in Section 313(c) of the TIA, unless in each case such
Defaults shall have been cured before the mailing or publication of such notice;
provided, however, that, except in the case of Default in the payment of the
principal of or interest on any of the Securities, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee, or a trust committee of directors or trustees or
Responsible Officers of the Trustee, or any combination of the foregoing, in
good faith determines that the withholding of such notice is in the interests of
the Securityholders.
 
     SECTION 7.12  Right of Court to Require Filing of Undertaking to Pay
Costs.  All parties to this Indenture agree, and each Holder of any Security by
its acceptance thereof shall be deemed to have agreed,
 
                                       30
<PAGE>   37
 
that any court may in its discretion require, in any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken, suffered or omitted by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit, having due regard to
the merit and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Securityholder or group of
Securityholders holding in the aggregate more than 10% in aggregate principal
amount of the Securities or to any suit instituted by any Securityholder for the
enforcement of the payment of the principal of or interest on any Security on or
after the due date expressed in such Security or any date fixed for redemption.
 
                                 ARTICLE EIGHT
 
                             CONCERNING THE TRUSTEE
 
     SECTION 8.1  Duties and Responsibilities of the Trustee; During Default;
Prior to Default.  With respect to the Holders of the Securities issued
hereunder, the Trustee, prior to the occurrence of an Event of Default with
respect to the Securities and after the curing or waiving of all Events of
Default that may have occurred, has undertaken to perform such duties and only
such duties as are specifically set forth in this Indenture. In case an Event of
Default with respect to the Securities has occurred (that has not been cured or
waived), the Trustee shall exercise with respect to such Securities such of the
rights and powers vested in it by this Indenture, and use the same degree of
care and skill in their exercise, as a prudent man would exercise or use under
the circumstances in the conduct of his own affairs.
 
     No provision of this Indenture shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or
its own wilful misconduct, except that:
 
          (a) prior to the occurrence of an Event of Default with respect to the
     Securities and after the curing or waiving of all such Events of Default
     with respect to such Securities that may have occurred:
 
             (i) the duties and obligations of the Trustee with respect to the
        Securities shall be determined solely by the express provisions of this
        Indenture, and the Trustee shall not be liable except for the
        performance of such duties and obligations as are specifically set forth
        in this Indenture, and no implied covenants or obligations shall be read
        into this Indenture against the Trustee; and
 
             (ii) in the absence of bad faith on the part of the Trustee, the
        Trustee may conclusively rely, as to the truth of the statements and the
        correctness of the opinions expressed therein, upon any statements,
        certificates or opinions furnished to the Trustee and conforming to the
        requirements of this Indenture; but in the case of any such statements,
        certificates or opinions that by any provision hereof are specifically
        required to be furnished to the Trustee, the Trustee shall be under a
        duty to examine the same to determine whether or not they conform to the
        requirements of this Indenture;
 
          (b) the Trustee shall not be liable for any error of judgment made in
     good faith by a Responsible Officer or Responsible Officers of the Trustee,
     unless it shall be proved that the Trustee was negligent in ascertaining
     the pertinent facts; and
 
          (c) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the Holders pursuant to Section 7.9 relating to the time, method and
     place of conducting any proceeding for any remedy available to the Trustee,
     or exercising any trust or power conferred upon the Trustee, under this
     Indenture.
 
     None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there shall be reasonable ground for believing that the
repayment of such funds or adequate indemnity against such liability is not
reasonably assured to it.

     Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.
 
     The provisions of this Section 8.1 are in furtherance of and subject to
Section 315 of the TIA.
 
     SECTION 8.2  Certain Rights of the Trustee.  In furtherance of and subject
to the TIA, and subject to Section 8.1:
 
          (a) the Trustee may rely and shall be protected in acting or
     refraining from acting upon any resolution, Officers' Certificate or any
     other certificate, statement, instrument, opinion, report, notice, request,
     consent, order, bond, debenture, note, coupon, security or other paper or
     document believed by it to be genuine and to have been signed or presented
     by the proper party or parties;
 
          (b) any request, direction, order or demand of the Company mentioned
     herein shall be sufficiently evidenced by an Officers' Certificate of the
     Company (unless other evidence in respect thereof be herein specifically
     prescribed); and any resolution of the Board of Directors of the Company
     may be evidenced to the Trustee by a copy thereof certified by the
     secretary or an assistant secretary of the Company;
 
          (c) the Trustee may consult with counsel and any written advice or any
     Opinion of Counsel shall be full and complete authorization and protection
     in respect of any action taken, suffered or omitted to be taken by it
     hereunder in good faith and in reliance thereon in accordance with such
     advice or Opinion of Counsel;
 
          (d) the Trustee shall be under no obligation to exercise any of the
     trusts or powers vested in it by this Indenture at the request, order or
     direction of any of the Securityholders pursuant to the provisions of this
     Indenture, unless such Securityholders shall have offered to the Trustee
     reasonable security or indemnity against the costs, expenses and
     liabilities that might be incurred therein or thereby;
 
          (e) the Trustee shall not be liable for any action taken or omitted by
     it in good faith and believed by it to be authorized or within the
     discretion, rights or powers conferred upon it by this Indenture; and
 
          (f) prior to the occurrence of an Event of Default hereunder and after
     the curing or waiving of all Events of Default, the Trustee shall not be
     bound to make any investigation into the facts or matters stated in any
     resolution, certificate, statement, instrument, opinion, report, notice,
     request, consent, order, approval, appraisal, bond, debenture, note,
     coupon, security, or other paper or document unless requested in writing to
     so do by the Holders of not less than a majority in aggregate principal
     amount of the Securities then Outstanding; provided, however, that, if the
     payment within a reasonable time to the Trustee of the costs, expenses, or
     liabilities likely to be incurred by it in the making of such investigation
     is, in the opinion of the Trustee, not reasonably assured to the Trustee by
     the security afforded to it by the terms of this Indenture, the Trustee may
     require reasonable indemnity against such expenses or liabilities as a
     condition to proceeding; the reasonable expenses of every such
     investigation shall be paid by the Company or, if paid by the Trustee or
     any predecessor Trustee, shall be repaid by the Company upon demand.
 
     SECTION 8.3  Trustee Not Responsible for Recitals, Disposition of
Securities or Application of Proceeds Thereof.  The recitals contained herein
and in the Securities, except the Trustee's certificates of authentication,
shall be taken as the statements of the Company and the Trustee assumes no
responsibility for the correctness of the same. The Trustee makes no
representation as to the validity or sufficiency of this Indenture or of the
Securities. The Trustee shall not be accountable for the use or application by
the Company of any of the Securities or of the proceeds thereof.
 
     SECTION 8.4  Trustee and Agents May Hold Securities; Collections, etc.  The
Trustee or any agent of the Company or the Trustee, in its individual or any
other capacity, may become the owner or pledgee of Securities with the same
rights it would have if it were not the Trustee or such agent and may otherwise
deal with the Company and receive, collect, hold and retain collections from the
Company with the same rights it would have if it were not the Trustee or such
agent.
 
                                       32
<PAGE>   39
 
     SECTION 8.5  Monies Held by Trustee.  Subject to the provisions of Section
11.4 hereof, all monies received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were received,
but need not be segregated from other funds except to the extent required by
mandatory provisions of law. Neither the Trustee nor any agent of the Company or
the Trustee shall be under any liability for interest on any monies received by
it hereunder.
 
     SECTION 8.6  Compensation and Indemnification of Trustee and Its Prior
Claim.  The Company covenants and agrees to pay to the Trustee from time to
time, and the Trustee shall be entitled to, reasonable compensation (which shall
not be limited by any provision of law in regard to the compensation of a
trustee of an express trust) and the Company covenants and agrees to pay or
reimburse the Trustee and each predecessor Trustee upon its request for all
reasonable expenses, disbursements and advances incurred or made by or on behalf
of it in accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all agents and other persons not regularly in its employ) except any such
expense, disbursement or advance as may arise from its negligence or bad faith.
The Company also covenants to indemnify the Trustee and each predecessor Trustee
for, and to hold it harmless against, any loss, liability or expense incurred,
without negligence or bad faith on its part, arising out of or in connection
with the acceptance or administration of this Indenture or the trusts hereunder
and its duties hereunder, including the costs and expenses of defending itself
against or investigating any claim of liability in the premises. The obligations
of the Company under this Section to compensate and indemnify the Trustee and
each predecessor Trustee and to pay or reimburse the Trustee and each
predecessor Trustee for expenses, disbursements and advances shall constitute
additional indebtedness of the Company hereunder and shall survive the
satisfaction and discharge of this Indenture. Such additional indebtedness shall
be a senior claim to that of the Securities upon all property and funds held or
collected by the Trustee as such, except funds held in trust for the benefit of
the Holders of particular Securities, and the Securities are hereby subordinated
to such senior claim.
 
     SECTION 8.7  Right of Trustee to Rely on Officers' Certificate,
etc.  Subject to Sections 8.1 and 8.2, whenever in the administration of this
Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or bad faith on the
part of the Trustee, be deemed to be conclusively proved and established by an
Officers' Certificate of the Company delivered to the Trustee, and such
certificate, in the absence of negligence or bad faith on the part of the
Trustee, shall be full warrant to the Trustee for any action taken, suffered or
omitted by it under the provisions of this Indenture upon the faith thereof.
 
     SECTION 8.8  Persons Eligible for Appointment as Trustee.  The Trustee
shall at all times be a corporation organized and doing business under the laws
of the United States of America or of any State or the District of Columbia, or
a corporation or other Person permitted to act as Trustee by the Commission
pursuant to the TIA, having a combined capital and surplus of at least
$50,000,000, and that is authorized under such laws to exercise corporate trust
powers and is subject to supervision or examination by Federal, State or
District of Columbia authority. Such corporation shall have an address in the
Borough of Manhattan, The City of New York for the presentment of Securities. If
such corporation publishes reports of condition at least annually, pursuant to
law or to the requirements of the aforesaid supervising or examining authority,
then for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. In case at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section, the Trustee shall resign immediately in the manner and with the effect
specified in Section 8.9.
 
     The provisions of this Section 8.8 are in furtherance of and subject to
Section 310(a) of the TIA.
 
     SECTION 8.9  Resignation and Removal; Appointment of Successor Trustee.
 
          (a) The Trustee, or any trustee or trustees hereafter appointed, may
     at any time resign by giving written notice of resignation to the Company
     and by mailing notice of such resignation to the Holders of then
     Outstanding Securities at their addresses as they shall appear on the
     registry books. Upon receiving such notice of resignation, the Company
     shall promptly appoint a successor trustee or trustees by written
 
                                       33
<PAGE>   40
 
     instrument in duplicate, executed by authority of the Board of Directors of
     the Company, one copy of which instrument shall be delivered to the
     resigning Trustee and one copy to the successor trustee or trustees. If no
     successor trustee shall have been so appointed and have accepted
     appointment within 30 days after the mailing of such notice of resignation,
     the resigning trustee may petition any court of competent jurisdiction for
     the appointment of a successor trustee, or any Securityholder who has been
     a bona fide Holder of a Security or Securities for at least six months may,
     subject to the provisions of Section 8.12, on behalf of itself and all
     others similarly situated, petition any such court for the appointment of a
     successor trustee. Such court may thereupon, after such notice, if any, as
     it may deem proper and prescribe, appoint a successor trustee.
 
          (b) In case at any time any of the following shall occur:
 
             (i) the Trustee shall fail to comply with the provisions of Section
        310(b) of the TIA with respect to the Securities after written request
        therefor by the Company or by any Securityholder who has been a bona
        fide Holder of a Security or Securities for at least six months; or
 
             (ii) the Trustee shall cease to be eligible in accordance with the
        provisions of Section 8.8 and Section 310(a) of the TIA and shall fail
        to resign after written request therefor by the Company or by any
        Securityholder; or
 
             (iii) the Trustee shall become incapable of acting or shall be
        adjudged a bankrupt or insolvent, or a receiver or liquidator of the
        Trustee or of its property shall be appointed, or any public officer
        shall take charge or control of the Trustee or of its property or
        affairs for the purpose of rehabilitation, conservation or liquidation;
 
     then, in any such case, unless the Trustee's duty to resign has been stayed
     as provided pursuant to Section 310(b) of the TIA, the Company may remove
     the Trustee and appoint a successor trustee by written instrument, in
     duplicate, executed by order of the Board of Directors of the Company, one
     copy of which instrument shall be delivered to the Trustee so removed and
     one copy to the successor trustee, or, subject to the provisions of Section
     315(e) of the TIA, any Securityholder who has been a bona fide Holder of a
     Security or Securities of such series for at least six months may on behalf
     of himself and all others similarly situated, petition any court of
     competent jurisdiction for the removal of the Trustee and the appointment
     of a successor trustee. Such court may thereupon, after such notice, if
     any, as it may deem proper and prescribe, remove the Trustee and appoint a
     successor trustee.
 
          (c) The Holders of a majority in aggregate principal amount of the
     Securities at the time Outstanding may at any time remove the Trustee and
     appoint a successor trustee by delivering to the Trustee so removed, to the
     successor trustee so appointed, and to the Company the evidence provided
     for in Section 9.1 of the action in that regard taken by the
     Securityholders.
 
          (d) Any resignation or removal of the Trustee and any appointment of a
     successor trustee pursuant to any of the provisions of this Section 8.9
     shall become effective upon acceptance of appointment by the successor
     trustee as provided in Section 8.10.
 
     SECTION 8.10  Acceptance of Appointment by Successor Trustee.  Any
successor trustee appointed as provided in Section 8.9 shall execute and deliver
to the Company and to its predecessor Trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor Trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all rights,
powers, duties and obligations of its predecessor hereunder, with like effect as
if originally named as trustee hereunder; but nevertheless, on the written
request of the Company or of the successor trustee, upon payment of its charges
then unpaid, the Trustee ceasing to act shall, subject to Section 11.4, pay over
to the successor trustee all monies at the time held by it hereunder and shall
execute and deliver an instrument transferring to such successor trustee all
such rights, powers, duties and obligations. Upon request of any such successor
trustee, the Company shall execute any and all instruments in writing for more
fully and certainly vesting in and confirming to such successor trustee all such
rights and powers. Any Trustee ceasing to act shall, nevertheless, retain a
prior claim upon all property or funds held or collected by such trustee to
secure any amounts then due it pursuant to the provisions of Section 8.6.
 
                                       34
<PAGE>   41
 
     No successor trustee shall accept appointment as provided to this Section
8.10 unless at the time of such acceptance such successor trustee shall be
qualified under Section 310(b) of the TIA and eligible under the provisions of
Section 8.8.
 
     Upon acceptance of appointment by any successor trustee as provided in this
Section 8.10, the Company shall give notice thereof to the Holders of
Securities, by mailing such notice to such Holders at their addresses as they
shall appear on the registry books. If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for
by the preceding sentence may be combined with the notice called for by Section
8.9. If the Company fails to give such notice within ten days after acceptance
of appointment by the successor trustee, the successor trustee shall cause such
notice to be given at the expense of the Company.
 
     SECTION 8.11  Merger, Conversion, Consolidation or Succession to Business
of Trustee.  Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to the corporate trust business of the Trustee, shall
be the successor of the Trustee hereunder; provided, however, that such
corporation shall be qualified under Section 310(b) of the TIA and eligible
under the provisions of Section 8.8, without the execution or filing of any
paper or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding.
 
     In case at the time such successor to the Trustee shall succeed to the
trust created by this Indenture any of the Securities shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the
certificate of authentication of any predecessor Trustee and deliver such
Securities so authenticated; and, in case at that time any of the Securities
shall not have been authenticated, any successor to the Trustee may authenticate
such Securities either in the name of any predecessor Trustee hereunder or in
the name of the successor Trustee; and in all such cases such certificate shall
have the full force that it has anywhere in the Securities or in this Indenture
provided that the certificate of the Trustee shall have; provided, however, that
the right to adopt the certificate of authentication of any predecessor Trustee
or to authenticate Securities in the name of any predecessor Trustee shall apply
only to its successor or successors by merger, conversion or consolidation.
 
     SECTION 8.12  Preferential Collection of Claims Against the Company.  The
Trustee shall comply with Section 311(a) of the TIA. Any Trustee that has
resigned or been removed is subject to Section 311(s) of the TIA to the extent
indicated therein.
 
     SECTION 8.13  Appointment of Authenticating Agent.  As long as any
Securities remain Outstanding, the Trustee may, by an instrument in writing,
appoint an authenticating agent (the "Authenticating Agent") that shall be
authorized to act on behalf of the Trustee to authenticate Securities, including
Securities issued upon exchange, registration of transfer, partial redemption or
pursuant to Section 2.5. Securities authenticated by such Authenticating Agent
shall be entitled to the benefits of this Indenture and shall be valid and
obligatory for all purposes as if authenticated by the Trustee. Whenever
reference is made in this Indenture to the authentication and delivery of
Securities by the Trustee or to the Trustee's Certificate of Authentication
(including, without limitation, in Section 2.3), such reference shall be deemed
to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a Certificate of Authentication executed on behalf of
the Trustee by such Authenticating Agent. Such Authenticating Agent shall at all
times be a corporation organized and doing business under the laws of the United
States of America or of any State or the District of Columbia, authorized under
such laws to exercise corporate trust powers, having a combined capital and
surplus of at least $5,000,000 (determined as provided in Section 8.8 with
respect to the Trustee) and subject to supervision or examination by Federal or
State authority.
 
     Any corporation into which any Authenticating Agent may be merged or
converted, or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency business
of any Authenticating Agent, shall continue to be the Authenticating Agent with
respect to all Securities for which it served as Authenticating Agent without
the execution or filing of any paper or any further act on the part of
 
                                       35
<PAGE>   42
 
the Trustee or such Authenticating Agent. Any Authenticating Agent may at any
time, and if it shall cease to be eligible shall, resign by giving written
notice of resignation to the Trustee and to the Company.
 
     Upon receiving such a notice of resignation or upon such a termination, or
in case at any time any Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section 8.13, the Trustee shall upon
receipt of an Company Order appoint a successor Authenticating Agent and the
Company shall provide notice of such appointment to all Holders in the manner
and to the extent provided in Section 12.4. Any successor Authenticating Agent
upon acceptance of its appointment hereunder shall become vested with all
rights, powers, duties and responsibilities of its predecessor hereunder, with
like effect as if originally named as Authenticating Agent. The Company agrees
to pay to the Authenticating Agent from time to time reasonable compensation.
The Authenticating Agent for the Securities shall have no responsibility or
liability for any action taken by it as such at the direction of the Trustee.
 
     Sections 8.2, 8.3, 8.4, 8.6, 8.8 and 9.3 shall be applicable to any
Authenticating Agent as if each reference to "Trustee" therein referred to the
Authenticating Agent.

                         CONCERNING THE SECURITYHOLDERS
 
     SECTION 9.1  Evidence of Action Taken by Securityholders.  Any request
demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by a specified percentage in
principal amount of the Securityholders may be embodied in and evidenced by one
or more instruments of substantially similar tenor signed by such specified
percentage of Securityholders in person or by agent duly appointed in writing;
and, except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee.
Proof of execution of any instrument or of a writing appointing any such agent
shall be sufficient for any purpose of this Indenture and (subject to Sections
8.1 and 8.2) conclusive in favor of the Trustee and the Company, if made in the
manner provided in this Article Nine.
 
     SECTION 9.2  Proof of Execution of Instruments and of Holding of
Securities.  Subject to Sections 8.1 and 8.2, the execution of any instrument by
a Securityholder or his agent or proxy may be proved in the following manner:
 
          (a) The fact and date of the execution by any Holder of any instrument
     may be proved by the certificate of any notary public or other officer of
     any jurisdiction authorized to take acknowledgments of deeds or administer
     oaths that the person executing such instruments acknowledged to him the
     execution thereof, or by an affidavit of a witness to such execution sworn
     to before any such notary or other such officer. Where such execution is by
     or on behalf of any legal entity other than an individual, such certificate
     or affidavit shall also constitute sufficient proof of the authority of the
     person executing the same.
 
          (b) The ownership of Securities shall be proved by the Security
     register or by a certificate of the Security registrar.
 
     The Company may set a record date for purposes of determining the identity
of Holders of Securities entitled to vote or consent to any action referred to
in Section 9.1, which record date may be set at any time or from time to time by
notice to the Trustee, for any date or dates (in the case of any adjournment or
reconsideration not more than 60 days nor less than five days prior to the
proposed date of such vote or consent, and thereafter, notwithstanding any other
provisions hereof, only Holders of Securities of record on such record date
shall be entitled to so vote or give such consent or revoke such vote or
comment.
 
     SECTION 9.3  Holders to be Treated as Owners.  The Company, the Trustee and
any agent of the Company or the Trustee may deem and treat the person in whose
name any Security shall be registered upon the Security register as the absolute
owner of such Security (whether or not such Security shall be overdue and
notwithstanding any notation of ownership or other writing thereon) for the
purpose of receiving payment of or on account of the principal of, premium (if
any) and interest on such Security and for all other purposes,
 
                                       36
<PAGE>   43
 
and neither the Company or the Trustee nor any agent of the Company or the
Trustee shall be affected by any notice to the contrary.
 
     SECTION 9.4  Securities Owned by the Company Deemed Not Outstanding.  In
determining whether the Holders of the requisite aggregate principal amount of
Outstanding Securities have concurred in any direction, consent or waiver under
this Indenture, Securities that are owned by the Company or any other obligor on
the Securities with respect to which such determination is being made or by any
Affiliate of the Company or any other obligor on the Securities with respect to
which such determination is being made shall be disregarded and deemed not to be
Outstanding for the purpose of any such determination, except that for the
purpose of determining whether the Trustee shall be protected in relying on any
such direction, consent or waiver only Securities that the Trustee knows are so
owned shall be so disregarded. Securities so owned that have been pledged in
good faith may be regarded as Outstanding if the pledgee establishes to the
satisfaction of the Trustee the pledgee's right so to act with respect to such
Securities and that the pledgee is not the Company or any other obligor upon the
Securities or any person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company or any other obligor on
the Securities. In case of a dispute as to such right, the advice of counsel
shall be full protection in respect of any decision made by the Trustee in
accordance with such advice. Upon request of the Trustee, the Company shall
furnish to the Trustee promptly an Officer's Certificate listing and identifying
all Securities, if any, known by the Company, to be owned or held by or for the
account of any of the above-described persons; and, subject to Sections 8.1 and
8.2, the Trustee shall be entitled to accept such Officer's Certificate as
conclusive evidence of the facts therein set forth and of the fact that all
Securities not listed therein are Outstanding for the purpose of any such
determination.
 
     SECTION 9.5  Right of Revocation of Action Taken.  At any time prior to
(but not after) the evidencing to the Trustee, as provided in Section 9.1, of
the taking of any action by the Holders of the percentage in aggregate principal
amount of the Securities specified in this Indenture in connection with such
action, any Holder of a Security the serial number of which is shown by the
evidence to be included among the serial numbers of the Securities the Holders
of which have consented to such action may, by filing written notice at the
Corporate Trust Office and upon proof of holding as provided in this Article
Nine, revoke such action so far as it concerns such Security. Except as
aforesaid, any such action taken by the Holder of any Security shall be
conclusive and binding upon such Holder and upon all future Holders and owners
of such Security and of any Securities issued in exchange of substitution
therefor or on registration of transfer thereof, irrespective of whether or not
any notation in regard thereto is made upon any such Security. Any action taken
by the Holders of the percentage in aggregate principal amount of the Securities
specified in this Indenture in connection with such action shall be conclusively
binding upon the Company, the Trustee and the Holders of all the Securities
affected by such action.

                                   AMENDMENTS
 
     SECTION 10.1  Amendments and Supplements Permitted Without Consent of
Holders.
 
          (a) Notwithstanding Section 10.2, the Company and the Trustee may
     amend or supplement this Indenture or the Securities without the consent of
     any Holder to: (i) cure any ambiguity, correct or supplement any provisions
     herein which may be inconsistent with any other provision herein, or to
     make any other provisions with respect to matters or questions arising
     under this Indenture which shall not be inconsistent with the provisions of
     this Indenture; provided that such amendment does not adversely affect the
     rights of the Holders; (ii) provide for uncertificated Securities in
     addition to or in place of certificated Securities; (iii) evidence the
     succession of another corporation to the Company and provide for the
     assumption by such successor of the Company's obligations to the Holders
     hereunder and under the Notes as permitted under Article Six; (iv) make any
     change that would (1) provide any additional rights or benefits to Holders
     or (2) not adversely affect the legal rights under the Indenture of any
     Holder, or (v) comply with the requirements of the Commission in order to
     effect or maintain the qualification of this Indenture under the TIA.

          (b) Upon the Company's request, after receipt by the Trustee of a
     resolution of the Board of Directors authorizing the execution of any
     amended or supplemental indenture, and the documents described in Section
     10.6, the Trustee shall join with the Company in the execution of any
     amended or supplemental indenture authorized or permitted by the terms of
     this Indenture and to make any further appropriate agreements and
     stipulations that may be contained in any such amended or supplemental
     indenture, but the Trustee shall not be obligated to enter into an amended
     or supplemental indenture that affects its own rights, duties or immunities
     under this Indenture or otherwise.
 
     SECTION 10.2  Amendments and Supplements Requiring Consent of Holders.
 
          (a) Except as otherwise provided in Section 10.1(a) and 10.2(c), this
     Indenture and the Securities may be amended or supplemented with the
     written consent of the Holders of at least a majority in aggregate
     principal amount of the then outstanding Securities (including consents
     obtained in connection with a tender offer or exchange offer for the
     Securities), and any existing Default or Event of Default or non-compliance
     with any provision of the Indenture or the Securities may be waived with
     the consent of Holders of at least a majority in principal of the then
     outstanding Securities (including consents obtained in connection with a
     tender offer or exchange offer for the Securities).
 
          (b) Upon the Company's request and after receipt by the Trustee of a
     resolution of the Board of Directors authorizing the execution of any
     supplemental indenture, evidence of the Holders' consent, and the documents
     described in Section 10.6, the Trustee shall join with the Company in the
     execution of such amended or supplemental indenture unless such amended or
     supplemental indenture affects the Trustee's own rights, duties or
     immunities under this Indenture or otherwise, in which case the Trustee may
     in its discretion, but shall not be obligated to, enter into such amended
     or supplemental indenture.
 
          (c) Without the consent of each Holder affected, no amendment,
     supplement or waiver to this Indenture shall: (i) reduce the principal
     amount of Securities whose Holders must consent to an amendment, supplement
     or waiver of any provision of this Indenture on the Securities, (ii) reduce
     the principal of or change the fixed maturity of any Security, or alter the
     provisions with respect to the redemption of the Securities in a manner
     adverse to the Holders, (iii) reduce the rate of or change the time for
     payment of interest on any Security, (iv) waive a Default or Event of
     Default in the payment of principal of, or premium (if any) or interest on,
     the Securities (except that Holders of at least a majority in aggregate
     principal amount of the then outstanding Securities may (1) rescind an
     acceleration of the Securities that resulted from a non-payment default,
     and (2) waive the payment default that resulted from such acceleration),
     (v) make any Security payable in money other than U.S. Legal Tender, (vi)
     make any change in the provisions of the Indenture relating to waivers of
     past Defaults or the rights of Holders to receive payments of principal of,
     or premium (if any) or interest on, the Securities, (vii) waive a
     redemption payment with respect to any Security, or (ix) make any change in
     Section 7.7, Section 7.10 or this sentence.
 
          (d) The Company may, but shall not be obligated to, fix a record date
     for the purpose of determining the Persons entitled to consent to any
     indenture supplemental hereto. If a record date is fixed, the Holders on
     such record date, or their duly designated proxies, and only such Persons,
     shall be entitled to consent to such supplemental indenture, whether or not
     such Holders remain Holders after such record date; provided, that unless
     such consent shall have become effective by virtue of the requisite
     percentage having been obtained prior to the date which is 90 days after
     such record date, any such consent previously given shall automatically and
     without further action by any Holder be cancelled and of no further effect.
 
          (e) It shall not be necessary for the consent of the Holders under
     this Section 10.2 to approve the particular form of any proposed amendment
     or waiver, but it shall be sufficient if such consent approves the
     substance thereof. After an amendment, supplement or waiver under this
     Section 10.2 becomes effective, the Company shall mail to each Holder
     affected thereby a notice briefly describing the amendment, supplement or
     waiver. Any failure of the Company to mail such notice, or any defect
     therein, shall not, however, in any way impair or affect the validity of
     any such amended or supplemental indenture or waiver.

     SECTION 10.3  Compliance with TIA.  Every amendment or supplement to this
Indenture or the Securities shall be set forth in an amended supplemental
indenture that complies with the TIA as then in effect.
 
     SECTION 10.4  Revocation and Effect of Consents.
 
          (a) Until an amendment, supplement or waiver becomes effective, a
     consent to it by a Holder of a Security is a continuing consent by the
     Holder and every subsequent holder of a Security or portion of a Security
     that evidences the same Indebtedness as the consenting Holder's Security,
     even if notation of the consent is not made on any Security. However, any
     such Holder or subsequent Holder may revoke the consent as to its Security
     or portion of a Security if the Trustee receives the notice of revocation
     before the date on which the Trustee receives an Officers' Certificate
     certifying that the Holders of the requisite principal amount of Securities
     have consented (and not theretofore revoked such consent) to the amendment
     or waiver.
 
          (b) The Company may, but shall not be obligated to, fix a record date
     for the purpose of determining the holders of Securities entitled to
     consent to any amendment or waiver. If a record date is fixed, then
     notwithstanding the provisions of the immediately preceding paragraph,
     those Persons who were holders of Securities at such record date (or their
     duly designated proxies), and only those Persons, shall be entitled to
     consent to such amendment or waiver or to revoke any consent previously
     given, whether or not such Persons continue to be holders of Securities
     after such record date. No consent shall be valid or effective for more
     than 90 days after such record date.
 
          (c) After an amendment or waiver becomes effective it shall bind every
     Holder, unless it is of the type described in Section 10.2(c), in which
     case the amendment or waiver shall only bind each Holder that consented to
     it and every subsequent holder of a Security that evidences the same debt
     as the consenting Holder's Security.
 
     SECTION 10.5  Notation on or Exchange of Securities.  The Trustee may place
an appropriate notation about an amendment, supplement or waiver on any Security
thereafter authenticated. The Company in exchange for all Securities may issue
and the Trustee shall authenticate new Securities that reflect the amendment,
supplement or waiver. Failure to make the appropriate notation or issue a new
Security shall not affect the validity and effect of such amendment, supplement
or waiver.
 
     SECTION 10.6  Trustee Protected.  The Trustee shall sign any amendment or
supplemental indenture authorized pursuant to this Article Ten if the amendment
does not adversely affect the rights, duties, liabilities or immunities of the
Trustee. If it does, the Trustee may, but need not, sign it. In signing such
amendment or supplemental indenture, the Trustee shall be entitled to receive
and, subject to Section 8.1, shall be fully protected in relying upon, an
Officers' Certificate and Opinion of Counsel as conclusive evidence that such
amendment or supplemental indenture is authorized or permitted by this
Indenture, that it is not inconsistent herewith, and that it will be valid and
binding upon the Company in accordance with its terms. The Company may not sign
an amendment or supplemental indenture until the Board of Directors approves it.

     SECTION 11.1  Satisfaction and Discharge of Indenture.
 
          (A) Except as otherwise provided in this Section 11.1, the Company may
     terminate its obligations under the Securities and this Indenture with
     respect to the Securities if:
 
             (i) all Securities previously authenticated and delivered (other
        than destroyed, lost or stolen Securities that have been replaced or
        Securities that are paid pursuant to Section 4.1 of this Indenture or
        Securities for whose payment money or securities have theretofore been
        held in trust and thereafter repaid to the Company, as provided in
        Section 11.4 of this Indenture) have been

          delivered to the Trustee for cancellation and the Company has paid all
          sums payable by it hereunder; or
 
             (ii) (A) the Securities mature within one year or all of them are
        to be called for redemption within one year under arrangements
        satisfactory to the Trustee for giving the notice of redemption, (B) the
        Company irrevocably deposits in trust with the Trustee during such
        one-year period, under the terms of an irrevocable trust agreement in
        form and substance satisfactory to the Trustee, as trust funds solely
        for the benefit of the Holders for that purpose, money or U.S.
        Government Obligations sufficient (in the opinion of a nationally
        recognized firm of independent public accountants expressed in a written
        certification thereof delivered to the Trustee), without consideration
        of any reinvestment of any interest thereon, to pay principal and
        interest on the Securities to maturity or redemption, as the case may
        be, and to pay all other sums payable by it hereunder, (C) no Event of
        Default with respect to the Securities shall have occurred and be
        continuing on the date of such deposit, (D) such deposit will not result
        in a breach or violation of, or constitute a default under, this
        Indenture or any other agreement or instrument to which the Company is a
        party or by which either is bound and (E) the Company has delivered to
        the Trustee an Officers' Certificate and an Opinion of Counsel, in each
        case stating that all conditions precedent provided for herein relating
        to the satisfaction and discharge of this Indenture have been complied
        with.
 
     With respect to the foregoing clause (i), the Company's obligations under
Section 8.6 shall survive. With respect to the foregoing clause (ii), the
Company's obligations in Sections 2.2, 2.3, 2.4, 2.5, 2.6, 4.1, 4.2, 4.3, 4.4,
8.6, 8.9, 11.2, 11.4 and 11.5 of this Indenture shall survive until the
Securities are no longer outstanding. Thereafter, only the Company's obligations
in Section 8.6 and 11.2 of this Indenture shall survive. After any such
irrevocable deposit, the Trustee upon request shall acknowledge in writing the
discharge of the Company's obligations under the Securities and this Indenture
with respect to the Securities except for those surviving obligations specified
above.
 
          (B) The Company will be deemed to have paid and will be discharged
     from any and all obligations in respect of the Securities on the 123rd day
     after the deposit referred to in clause (d) of this paragraph, and the
     provisions of this Indenture will no longer be in effect with respect to
     the Securities, except as to (i) rights of registration of transfer and
     exchange, (ii) substitution of apparently mutilated, defaced, destroyed,
     lost or stolen Securities, (iii) rights of Holders to receive payments of
     principal thereof and interest thereon, (iv) the Company's obligations
     under Section      , (v) the rights, obligations and immunities of the
     Trustee hereunder and (vi) the rights of the Holders of Securities as
     beneficiaries of this Indenture with respect to the property so deposited
     with the Trustee payable to all or any of them, and the Trustee, at the
     expense of the Company, shall at the Company's request execute proper
     instruments acknowledging the same; provided that the following conditions
     shall have been satisfied:
 
             (a) with reference to this Section 11.1(B), the Company has
        irrevocably deposited or caused to be irrevocably deposited with the
        Trustee (or another trustee satisfying the requirements of Section 8.8)
        and conveyed all right, title and interest for the benefit of the
        Holders of the Securities, under the terms of an irrevocable trust
        agreement in form and substance satisfactory to the Trustee as trust
        funds in trust, in and to (1) money in an amount, (2) U.S. Government
        Obligations that, through the payment of interest and principal in
        respect thereof in accordance with their terms, will provide, not later
        than one day before the due date of any payment referred to in this
        clause (a), money in an amount or (3) a combination thereof in an amount
        sufficient, in the opinion of a nationally recognized firm of
        independent public accountants expressed in a written certification
        thereof delivered to the Trustee, to pay and discharge, without
        consideration of the reinvestment of such interest and after payment of
        all federal, state and local taxes or other charges and assessments in
        respect thereof payable by the Trustee, the principal of, premium, if
        any, and interest on the outstanding Securities at the Stated Maturity
        of such principal or interest; provided that the Trustee shall have been
        irrevocably instructed to apply such money or the proceeds of such U.S.
        Government Obligations to the payment of such principal, premium, if
        any, and interest with respect to the Securities;
 
                                       40
<PAGE>   47
 
             (b) such deposit will not result in a breach or violation of, or
        constitute a default under, this Indenture or any other agreement or
        instrument to which the Company is a party or by which either is bound;
 
             (c) the Company shall have delivered to the Trustee (1) either (x)
        a ruling directed to the Trustee received from the Internal Revenue
        Service to the effect that the Holders of Securities will not recognize
        income, gain or loss for federal income tax purposes as a result of the
        Company's exercise of its option under this Section 11.1(B) and will be
        subject to federal income tax on the same amount and in the same manner
        and at the same times as would have been the case if such option had not
        been exercised or (y) an Opinion of Counsel to the same effect as the
        ruling described in clause (x) above and (2) an Opinion of Counsel to
        the effect that (w) the creation of the defeasance trust does not
        violate the Investment Company Act of 1940, (x) the Holders have a valid
        first-priority security interest in the trust funds and (y) after the
        passage of 123 days following the deposit (except, with respect to any
        trust funds for the account of any Holder who may be deemed to be an
        "insider" for purposes of the United States Bankruptcy Code, after one
        year following the deposit), the trust funds will not be subject to the
        effect of Section 547 of the United States Bankruptcy Code or Section 15
        of the New York Debtor and Creditor Law in a case commenced by or
        against the Company under either such statute, and either (I) the trust
        funds will not longer remain the property of the Company (and therefore
        will not be subject to the effect of any applicable bankruptcy,
        insolvency, reorganization or similar laws affecting creditors' rights
        generally) or (II) if a court were to rule under any such law in any
        case or proceeding that the trust funds remained property of the
        Company, (a) assuming such trust funds remained in the possession of the
        Trustee prior to such court ruling to the extent not paid to the
        Holders, the Trustee will hold, for the benefit of the Holders, a valid
        and perfected security interest in such trust funds that is not
        avoidable in bankruptcy or otherwise except for the effect of Section
        552(b) of the United States Bankruptcy Code on interest on the trust
        funds accruing after the commencement of a case under such statute and
        (b) the Holders will be entitled to receive adequate protection of their
        interests in such trust funds if such trust funds are used in such case
        or proceeding;
 
             (d) if the Securities are then listed on a national securities
        exchange, the Company shall have delivered to the Trustee an Opinion of
        Counsel to the effect that such deposit, defeasance and discharge will
        not cause the Securities to be delisted; and
 
             (e) the Company has delivered to the Trustee an Officers'
        Certificate and an Opinion of Counsel, in each case stating that all
        conditions precedent provided for herein relating to the defeasance
        contemplated by this Section 11.1(B) have been complied with.
 
     Notwithstanding the foregoing clause (a), prior to the end of the 123-day
period referenced to in clause (d)(2)(y) above, none of the Company's
obligations under this Indenture shall be discharged. Subsequent to the end of
such 123-day period with respect to this Section 11.1, the Company's obligations
in Sections 2.2, 2.3, 2.4, 2.5, 2.6, 4.1, 4.2, 4.3, 4.4, 8.6, 8.9, 11.2, 11.4
and 11.5 shall survive until the Securities are no longer outstanding.
Thereafter, only the Company's obligations in Section 8.6 and 11.2 shall
survive. If and when a ruling from the Internal Revenue Service or an Opinion of
Counsel referred to in clause (d)(1) above is able to be provided specifically
without regard to, and not in reliance upon, the continuance of the Company's
obligations under Section 4.1, then the Company's obligations under such Section
4.1 shall cease upon delivery to the Trustee of such ruling or Opinion of
Counsel and compliance with the other conditions precedent provided for herein
relating to the defeasance contemplated by this Section 11.1.
 
     After any such irrevocable deposit, the Trustee upon request, shall
acknowledge in writing the discharge of the Company's obligations under the
Securities and this Indenture with respect to the Securities except for those
surviving obligations in the immediately preceding paragraph.
 
          (C) The Company may omit to comply with any term, provision or
     condition set forth in clause (d) of Section 6.1 of this Indenture, the
     covenants described in Sections 4.11, 4.13, 4.14, 4.15 and 4.18 of this
     Indenture and clause (c) of Section 7.1 of this Indenture with respect to
     such covenants, and clauses (d),

     (e) and (h) of Section 7.1 shall be deemed not to be Events of Default, in
     each case with respect to the outstanding Securities if:
 
             (a) with reference to this Section 11.1(C), the Company has
        irrevocably deposited or caused to be irrevocably deposited with the
        Trustee (or another trustee satisfying the requirements of Section 8.8)
        and conveyed in and to all right, title and interest to the Trustee for
        the benefit of the Holders, under the terms of an irrevocable trust
        agreement in form and substance satisfactory to the Trustee as trust
        funds in trust, specifically pledged to the Trustee as security for
        payment of the principal of, premium, if any, and interest, in any, on
        the Securities for, and dedicated solely to, the benefit of the Holders
        of the Securities, in and to (1) money in an amount, (2) U.S. Government
        Obligations that, through the payment of interest and principal in
        respect thereof in accordance with their terms, will provide, not later
        than one day before the due date of any payment referred to in this
        clause (a), money in an amount or (3) a combination thereof in an amount
        sufficient, in the opinion of a nationally recognized firm of
        independent public accountants expressed in a written certification
        thereof delivered to the Trustee, to pay and discharge, without
        consideration of the reinvestment of such interest and after payment of
        all federal, state and local taxes or other charges and assessments in
        respect thereof payable by the Trustee, the principal of, premium, if
        any, and interest on the outstanding Securities on the Stated Maturity
        of such principal or interest; provided that the Trustee shall have been
        irrevocably instructed to apply such money or the proceeds of such U.S.
        Government Obligations to the payment of such principal, premium, if
        any, and interest with respect to the Securities;
 
             (b) such deposit will not result in a breach or violation of, or
        constitute a default under, this Indenture or any other agreement or
        instrument to which the Company is a party or by which it is bound;
 
             (c) no Default or Event of Default shall have occurred and be
        continuing on the date of such deposit;
 
             (d) the Company has delivered to the Trustee an Opinion of Counsel
        to the effect that (1) the creation of the defeasance trust does not
        violate the Investment Company Act of 1940, (2) the Holders of the
        Securities have a valid first-priority security interest in the trust
        funds, (3) the Holders will not recognize income, gain or loss for
        federal income tax purposes as a result of such deposit and defeasance
        of certain obligations and will be subject to federal income tax on the
        same amount and in the same manner and at the same times as would have
        been the case if such deposit and defeasance had not occurred and (4)
        after the passage of 123 days following the deposit (except, with
        respect to any trust funds for the account of any Holder who may be
        deemed to be an "insider" for purposes of the United States Bankruptcy
        Code, after one year following the deposit), the trust funds will not be
        subject to the effect of Section 547 of the United States Bankruptcy
        Code or Section 15 of the New York Debtor and Creditor Law in a case
        commenced by or against the Company under either such statute, and
        either (x) the trust funds will no longer remain the property of the
        Company (and therefore will not be subject to the effect of any
        applicable bankruptcy, insolvency, reorganization or similar laws
        affecting creditors' rights generally) or (y) if a court were to rule
        under any such law in any case or proceeding that the trust funds
        remained property of the Company, and (i) assuming such trust funds
        remained in the possession of the Trustee prior to such court ruling to
        the extent not paid to the Holders the Trustee will hold, for the
        benefit of the Holders, a valid and perfected security interest in such
        trustee funds that is not avoidable in bankruptcy or otherwise except
        for the effect of Section 552(b) of the United States Bankruptcy Code on
        interest on the trust funds accruing after the commencement of a case
        under such statute and (ii) the Holders will be entitled to receive
        adequate protection of their interests in such trust funds if such trust
        funds are used in such case or proceeding;
 
             (e) if the Securities are then listed on a national securities
        exchange, the Company shall have delivered to the Trustee an Opinion of
        Counsel to the effect that such deposit, defeasance and discharge will
        not cause the Securities to be delisted; and
 
                                       42
<PAGE>   49
 
             (f) the Company has delivered to the Trustee an Officers'
        Certificate and an Opinion of Counsel, in each case stating that all
        conditions precedent provided for herein relating to the defeasance
        contemplated by this Section 11.1 have been complied with.
 
     SECTION 11.2  Application by Trustee of Funds Deposited for Payment of
Securities; Other Miscellaneous Provisions.  Subject to Section 11.4, all monies
deposited with the Trustee (or other trustee) pursuant to Section 11.3 shall be
held in trust and applied by it to the payment, either directly or through any
Paying Agent (including the Company or the guarantor acting as Paying Agent), to
the Holders of the Securities for the payment or redemption of which such monies
have been deposited with the Trustee, of all sums due and to become due thereon
for principal premium, if any, and interest if may; but such money need not be
segregated from other funds except to the extent required by law.
 
   
     If the Trustee or any Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with Section 11.1 by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such applications, the
Company's obligations under this Indenture and the Securities related thereto
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 11.1B(a) or 11.1C(a) until such time as the Trustee or any Paying Agent
is permitted to apply all such money or U.S. Government Obligations in
accordance with Section 11.1; provided, however, that if the Company has made
any payment of interest on or principal of and premium (if any) on the
Securities because of the reinstatement of its obligations hereunder, the
Company shall be subrogated to the rights of the holders of the Securities to
receive such payment from the money or U.S. Government obligations held by the
Trustee for such purpose.
    
 
     SECTION 11.3  Repayment of Monies Held by Paying Agent.  In connection with
the satisfaction and discharge of this Indenture with respect to Securities, all
monies then held by any Paying Agent under the provisions of this Indenture with
respect to such Securities shall, upon demand of the Company, be repaid to the
Company or paid to the Trustee and thereupon such Paying Agent shall be released
from all further liability with respect to such monies.
 
     SECTION 11.4  Return of Monies Held by Trustee and Paying Agent Unclaimed
for Two Years.  Any monies deposited with or paid to the Trustee or any Paying
Agent for the payment of the principal of, premium (if any) or interest on any
Security and not applied but remaining unclaimed for two years after the date
upon which such principal or interest shall have become due and payable shall,
upon the written request of the Company and unless otherwise required by
mandatory provisions of applicable escheat or abandoned or unclaimed property
law, be repaid to the Company by the Trustee or such Paying Agent, and the
Holder of the Securities shall, unless otherwise required by mandatory
provisions of applicable escheat or abandoned or unclaimed property laws,
thereafter look only to the Company for any payment that such Holder may be
entitled to collect, and all liability of the Trustee or any Paying Agent with
respect to such monies shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment
with respect to monies deposited with it for any payment, may at the expense of
the Company, mail by first-class mail to Holders of such Securities at their
addresses as they shall appear on the security register notice, that such monies
remain and that, after a date specified therein, which shall not be less than
thirty days from the date of such mailing, any unclaimed balance of such money
then remaining will be, repaid to the Company.
 
     SECTION 11.5  Indemnity for U.S. Government Obligations.  The Company shall
pay and indemnify the Trustee against any tax, fee or other charge imposed on or
assessed against the U.S. Government Obligations deposited by the Company
pursuant to Section 11.1 or the principal or interest received in respect of
such obligations.

<PAGE>   50
 
Trustee shall have any liability for any obligation of the Company under this
Indenture or the Securities or for any claim based on, in respect of, or by
reason of, any such obligation or the creation of any such obligation. Each
Holder by accepting a Security waives and releases such Persons from all such
liability and such waiver and release is part of the consideration for the
issuance of the Securities.
 
     SECTION 12.2  Provisions of Indenture for the Sole Benefit of Parties and
Holders of Securities. Nothing in this Indenture or in the Securities expressed
or implied, shall give or be construed to give to any person, firm or
corporation, other than the parties hereto and their successors and the Holders
of the Securities any legal or equitable right, remedy or claim under this
Indenture or under any covenant or provision herein contained, all such
covenants and provisions being for the sole benefit of the parties hereto and
their successors and of the Holders of the Securities.
 
     SECTION 12.3  Successors and Assigns of the Company Bound by

expressly provided) it in writing and mailed, first-class postage prepaid, to
each Holder entitled thereto, at his last address an it appears in the Security
register. In any case where notice to such Holders is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders. Where this Indenture provides for notice in any manner, such
notice may be waived in writing by the person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of
such notice. Waivers of notice by Holders shall be filed with the Trustee, but
each filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.
 
     SECTION 12.5  Officers' Certificates and Opinions of Counsel; Statements to
be Contained Therein. Upon any application or demand by the Company to the
Trustee to take any action under any of the provisions of this Indenture, the

which the statements or opinions contained in such certificate or opinion are
based, (c) a statement that, in the opinion of such person, he has made such

person, such condition or covenant has been complied with.
 
     Any certificate, statement or opinion of an officer of the Company may be

certificate, statement or opinion may be based as aforesaid are erroneous, or in
the exercise of reasonable care should know that the same are erroneous. Any
certificate, statement or opinion of counsel may be based, insofar as it relates

is independent.
 
     SECTION 12.6  Payments Due on Saturdays, Sundays and Holidays.  If the date
of maturity of interest on or principal of the Securities the date fixed for
redemption or repayment of any Security shall not be a Business Day, then
payment of interest or principal need not be made on such date, but may be made
on the next succeeding Business Day with the same force and effect as if made on

accrue for the period after such date.

                        % SENIOR UNSECURED NOTES DUE 2001
 
1. INTEREST.
 
     America West Airlines, Inc., a Delaware corporation (the "Company"),
promises to pay interest on the unpaid principal amount of this Security to
Persons who are registered Holders at the close of business on the relevant
Record Date at the rate of    % per annum.
 
     Interest shall be computed on the basis of a 360-day year of twelve 30-day
months and shall be payable semi-annually on                15 and
               15 of each year commencing                15, 1994, or if any
such day is not a Business Day, on the next succeeding Business Day. Interest
will accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the date of issuance. Interest shall accrue with
respect to principal on this Security to, but not including the date of
repayment of such principal; provided, however, that if payment to the Paying
Agent occurs after 10:00 a.m., New York City time, interest shall be deemed to
accrue until the following Business Day.
 
     To the extent lawful, the Company shall pay interest on overdue principal,
premium (if any) and interest at the rate of interest borne by this Security. On
each Interest Payment Date, interest on the Securities will be paid for the
immediately preceding accrual period.
 
2. METHOD OF PAYMENT.
 
     The Company will pay interest on the Securities (except defaulted interest)
to the persons who are registered Holders at the close of business on the Record
Date next preceding the applicable Interest Payment Date. If the Company
defaults in the payment of the interest due on such Interest Payment Date, such

     The Trustee under the Indenture, in its individual or any other capacity,

                             CODE SHARING AGREEMENT
 
     This Agreement is made this 29th day of June, 1994, by and between

                                    RECITALS
 
     CAL and AWA are each certificated air carriers providing air transportation
services in their respective areas of operation.
 
     CAL and AWA desire to cooperate in the coordination of schedules by
allowing AWA to market its flight operations under the CO* designator and CAL to
market its flight operations under the HP* designator.
 
     NOW, THEREFORE, in consideration of the premises and the mutual promises
herein contained, CAL and AWA hereby agree as follows:
 
     1. Schedules to be Operated.  It is the intent of the parties to share
their two letter designator codes, "CO*" in the case of CAL and "HP*" in the
case of AWA. CAL operated Shared Code Segments (as herein defined) will be
marketed under not only CAL's "CO" designator code but also under AWA's "HP*"
designator code, and AWA operated Shared Code Segments will be marketed under
not only AWA's "HP" designator code, but also under CAL's "CO*" designator code.
Schedule 1 hereto sets forth the flight segments where shared code segments
("Shared Code Segments") will operate at the commencement of this Agreement and
some of the Shared Code Segments that will be operated in the future; however,
it is the intent of the carriers to designate, to the maximum extent permitted
by law, all flights operated by either as Share Code Segments during the term of
this Agreement. The carriers shall meet together every six months that this
Agreement is in effect to discuss the appropriateness of expanding or
contracting the list of city pairs on Schedule 1.
 
     2. Code Sharing Licenses.
 
          (a) CO* License.
 
             (i) Grant of License.  Subject to the terms and conditions of this
        Agreement, CAL hereby grants to AWA a nonexclusive, nontransferable,
        revocable license to use the CO* designator code on all of its flights
        operated as a Shared Code Segments. (AWA flights flown using the CO*
        code are hereinafter referred to as "CO* Flights").
 
             (ii) Control of CO* Flights.  AWA shall have sole responsibility
        for and control over, and CAL shall have no responsibility for, control
        over or obligations or duties with respect to, each and every aspect of
        AWA's operations including, without limitation, scheduling (except as
        provided in Section 12 hereto), pricing (except as provided in Section
        13 hereto), planning of flight itineraries and routings, reservations,
        reservations control/yield management, dispatch, fueling, weight and
        balance, flight release, maintenance, and flight operations and
        compliance with applicable rules and regulations.
 
          (b) HP* License.
 
             (i) Grant of License.  Subject to the terms and conditions of this
        Agreement, AWA hereby grants to CAL a nonexclusive, nontransferable,
        revocable license to use the HP* designator code on all of its flights
        operated as a Shared Code Segment. (CAL flights flown using the HP* code
        are hereinafter referred to as "HP* Flights").
 
             (ii) Control of HP* Flights.  CAL shall have sole responsibility
        for and control over, and AWA shall have no responsibility for, control
        over or obligations or duties with respect to, each and every aspect of
        CAL's operations including, without limitation, scheduling (except as
        provided in
 
                                        1
<PAGE>   2
 
          Section 12 hereto), pricing (except as provided in Section 13 hereto),
          planning of flight itineraries and routings, reservations,
          reservations control/yield management, dispatch, fueling, weight and
          balance, flight release, maintenance, and flight operations and
          compliance with applicable rules and regulations.
 
     3. Confidential Information.  Neither AWA nor CAL shall disclose to the
other carrier or be required to disclose by the other carrier any information
relating to its scheduling (except as provided in Section 12 hereto), pricing,
inventory control or flight profitability. Neither AWA nor CAL shall disclose
the terms of this Agreement or any proprietary information with respect to the
other obtained as a result of this Agreement, either during the term hereof or
thereafter except as may be required by law or by any order of a court or
administrative agency, and then on ten days' notice to the other. The parties
hereto recognize that, in the course of the performance of each of the
provisions hereof, each carrier may be given and may have access to confidential
and proprietary information of the other carrier, including proposed schedule
and fare changes, statistical data regarding loads and fares, sales and
promotional programs and other operating and competitive information
("Confidential Information"). Each carrier shall preserve, and shall ensure that
each of its officers, agents, consultants and employees who receive Confidential
Information preserve, the confidentiality of the other carrier's Confidential
Information.
 
     4. Quality of Service.  Each carrier shall perform its service with respect
to its flights operated under the designation of the other carrier in a timely,
expert and quality manner. Each carrier agrees that, in conducting flight
operations under the designator of the other carrier, it will employ prudent
safety and loss prevention policies.
 
     5. Audit.
 
          (a) CAL Audit.  CAL shall have the right, at its own cost, to inspect,
     review, and observe AWA's operations of CO* Flights, and/or to conduct a
     full safety and/or service audit of AWA's operations, manuals and
     procedures reasonably related to CO* Flights, at such intervals as CAL
     shall reasonably request. In the exercise of such right, CAL does not
     undertake any responsibility for the performance of AWA's operations. CAL
     shall coordinate its safety and service audits with AWA so as to avoid
     disruptions of AWA's operations. Any safety audit may include, without
     limitation, maintenance and operation procedures, crew planning,
     reservations, passenger and baggage handling, customer service, personnel
     records, spare parts, inventory records, training records and manuals,
     flight, flight training and operational personnel records. This paragraph
     shall not entitle CAL access to AWA's records, documents or systems
     relating to its pricing, inventory control or flight profitability.
 
          (b) AWA Audit.  AWA shall have the right, at its own cost, to inspect,
     review, and observe CAL's operations of HP* Flights, and/or to conduct a
     full safety and/or service audit of CAL's operations, manuals and
     procedures reasonably related to HP* Flights, at such intervals as AWA
     shall reasonably request. In the exercise of such right, AWA does not
     undertake any responsibility for the performance of CAL's operations. AWA
     shall coordinate its safety and service audits with CAL so as to avoid
     disruptions of CAL's operations. Any safety audit may include, without
     limitation, maintenance and operation procedures, crew planning,
     reservations, passenger and baggage handling, customer service, personnel
     records, spare parts, inventory records, training records and manuals,
     flight, flight training and operational personnel records. This paragraph
     shall not entitle AWA access to CAL's records, documents or systems
     relating to its pricing, inventory control or flight profitability.
 
     6. Public Relations.  In the event of any irregularity in Shared Code
Segments' operations, including, without limitation, any event causing damage to
persons or property, the operating carrier shall identify itself as being
operated independently of the carrier whose code is being used, and as being
solely responsible for its operations. Either carrier may state that it holds a
code sharing license from the other carrier and that it obtains certain services
from the other carrier if third parties inquire as to such relationship.
 
     7. Irregularities in Operations.  AWA shall promptly notify CAL of all
irregularities involving a CO* Flight which result in any damage to persons or
property as soon as such information is available and shall furnish to CAL as
much detail as practicable. CAL shall promptly notify AWA of all irregularities

     impracticable) of any intended (i) changes to its operating specifications,
     or (ii) material changes to the manner of conducting its business or the
     nature of its product. In the event any such change materially affects the
     value or risk to the other carrier of this Code Sharing Agreement in the
     other carrier's reasonable judgment, the other carrier shall be entitled to
     terminate this agreement if the change is implemented.
 
          (b) Correspondence from Government Authorities.  AWA shall immediately

     (ii) any investigation of AWA performed or proposed by any government
     authority, including, without limitation, any communication issued by a

     proposed by any government authority, including, without limitation, any
     communication issued by a government authority concerning the airworthiness
     of CAL's aircraft, the compliance of CAL's personnel with required

     parties. CAL shall monthly furnish AWA a summary of complaints, notices or
     violation, request to cease activity or similar correspondence which
     reasonably relate to HP* Flights and which are received by CAL from
     passengers, any government authority, or other parties. Each carrier shall
     comply with the other carrier's reasonable requests for actual copies of
     any such documents.

     fare displays of all computerized reservations systems in which CAL and AWA
     participate, the Official Airline Guide (to the extent agreed upon) and

     10. Terms and Conditions of Carriage and Claims Procedures.
 
          (a) In all cases the contract of carriage between a passenger and a
     carrier will be that of the carrier whose designator code is used and not
     that of the carrier operating the Shared Code Flight.
 
          (b) The carriers will use existing IATA procedures when handling and
     settling claims made by customers in connection with Shared Code Segments.
 
     11. Irregularity Handling.
 
          (a) In the event of flight delays, cancellations or other schedule
     irregularities that affect Shared Code Segments, the operating carrier will
     inform the carrier whose designator is also used of all pertinent
     information concerning an irregularity for customer information purposes.
 
          (b) The parties agree that they will cooperate in all available ways
     to accommodate passengers experiencing flight irregularities and that
     neither will forbear from providing such assistance because the other may
     have been responsible for the flight irregularity. In the event of a flight
     irregularity, the carrier causing or experiencing the irregularity shall
     bear all related costs associated with accommodating the passengers who
     have been delayed. The carriers will review existing procedures for
     accommodating interline passengers with respect to flight irregularities
     and oversales to determine their adequacy for the purposes of this
     Agreement and will make such adjustments in existing procedures as they
     find necessary or appropriate.
 
     12. Airport Operational Assistance.  CAL and AWA will cooperate to
coordinate and maintain their schedules to minimize the waiting time and to
maximize convenience of passengers who are connecting from a CAL to AWA flight
segment (or vice versa). Each carrier will provide the other with the airport
operational assistance that is required to assure schedule compatibility for
Shared Code Segments for which a Through Fare (as such term is hereinafter
defined) may be applicable. The carriers will use their respective best efforts
to align gates and ticket counter space where Shared Code Segments operate.
 
     13. Pricing and Capacity Control of Shared Code Segments.
 
                         [CONFIDENTIAL PORTION DELETED]
 
     15. Compliance with Laws and Regulations.  CAL and AWA each represent,
warrant, and agree that performance of its respective obligations under this
Agreement shall be conducted and all of its personnel shall at all times meet,
be in full compliance with and have all required licenses under any and all
applicable statutes, orders, rules and regulations, and satisfy all applicable
insurance requirements, whether in effect or hereafter promulgated of the United
States National Transportation Safety Board, Department of Transportation of
Federal Aviation Administration, Department of Defense of any country or
territory with jurisdiction over the Shared Code Segments.
 
     16. Independent Parties.
 
          (a) Independent Contractors.  It is expressly recognized and agreed
     that each carrier, in its performance and otherwise under this Agreement,
     is and shall be engaged and acting as an independent contractor and in its
     own independent and separate business; that each carrier shall retain
     complete and exclusive control over its staff and operations and the
     conduct of its business; and that each carrier shall bear and pay all
     expenses, costs, risks and responsibilities incurred by it in connection
     with its obligations under this Agreement. Neither CAL nor AWA nor any
     officer, employee, representative, or agent of CAL or AWA shall in any
     manner, directly or indirectly, expressly or by implication, be deemed to
     be, or make any representation or take any action which may give rise to
     the existence of, any employment, agent, partnership, or other like
     relationship as between CAL and AWA but each carrier's relationship as
     respects the other carrier in connection with this Agreement is and shall
     remain that of an independent contractor.
 
          (b) Status of Employees.  The employees, agents and/or independent
     contractors of AWA shall be employees, agents, and independent contractors
     of AWA for all purposes, and under no circumstances
 
                                        4
<PAGE>   5
 
     shall be deemed to be employees, agents or independent contractors of CAL.
     The employees, agents and independent contractors of CAL for all purposes,
     and under no circumstances shall be deemed to be employees, agents or
     independent contractors of AWA. In its performance under this Agreement,
     each carrier shall act as an independent contractor and not as an agent for
     the other. CAL shall have no supervisory power or control over any
     employees, agents or independent contractors employed by AWA, and AWA shall
     have no supervisory power or control over any employees, agents and
     independent contractors employed by CAL.
 
          (c) Liability For Employee Costs.  Each carrier, with respect to its
     own employees (hired directly or through a third party), accepts full and
     exclusive liability for the payment of worker's compensation and/or
     employer's liability (including insurance premiums where required by law)
     and for the payment of all taxes, contributions or other payments for
     unemployment compensation, vacations, or old age benefits, pensions and all
     other benefits now or hereafter imposed upon employers with respect to its
     employees by any government or agency thereof or any other party (whether
     measured by the wages, salaries, compensation or other remuneration paid to
     such employees or otherwise) and each carrier further agrees to make such
     payments and to make and file all reports and returns, and to do everything
     necessary to comply with the laws imposing such taxes, contributions or
     other payments.
 
     17. Indemnification and Insurance.
 
        (a) Indemnification.
 
             (i) AWA hereby assumes liability for, and shall indemnify, defend,
        protect, save and hold harmless CAL, its officers, agents, and employees
        from and against any and all liabilities, claims, judgments, damages,
        and losses, including all costs, fees, and expenses incidental thereto,
        of every type and nature whatsoever, including without limitation those
        involving (i) death of or injury to any person including, but not
        limited to, AWA's officers, employees and agents, (ii) loss of, damage
        to, or destruction of any property whatsoever, including any loss of use
        thereof, and (iii) trademark, service mark or trade name infringement,
        provided that such liabilities, claims, judgments, damages or losses are
        caused by or arise out of (or are alleged to be caused by or arise out
        of) any alleged acts or omissions of AWA or its officers, employees, or
        agents which are in any way related to the services contemplated by this
        Agreement. CAL shall give AWA prompt notice of any claim made or suit
        instituted against CAL which, if successful, would result in
        indemnification of CAL hereunder, and CAL shall have the right to
        compromise or participate in the defense of same to the extent of its
        own interest.
 
             (ii) CAL hereby assumes liability for, and shall indemnify, defend,
        protect, save and hold harmless AWA, its officers, agents, and employees
        from and against any and all liabilities, claims, judgments, damages,
        and losses, including all costs, fees, and expenses incidental thereto,
        of every type and nature whatsoever, including without limitation those
        involving (i) death of or injury to any person including, but not
        limited to, CAL's officers, employees and agents, (ii) loss of, damage
        to, or destruction of any property whatsoever, including any loss of use
        thereof, and (iii) trademark, service mark or trade name infringement,
        provided that such liabilities, claims, judgments, damages or losses are
        caused by or arise out of (or are alleged to be caused by or arise out
        of) any alleged acts or omissions of CAL or its officers, employees, or
        agents which are in any way related to the services contemplated by this
        Agreement. AWA shall give CAL prompt notice of any claim made or suit
        instituted against AWA which, if successful, would result in
        indemnification hereunder, and AWA shall have the right to compromise or
        participate in the defense of same to the extent of its own interest.
 
          (b) Insurance Coverage.
 
             (i) Each carrier shall, at all time during the term of this
        Agreement, maintain in full force and effect policies of insurance as
        follows:
 
                1. Comprehensive Airline Liability Insurance, including Aircraft
           Third Party, Passenger, including Passengers' Baggage and Personal
           Effects, Cargo and Mail Legal Liability for a

               Combined Single Limit (CSL) of not less than $500 million per
               occurrence per Aircraft. In respect of Personal Injury the
               maximum limit is $25 million per offense and in the aggregate.
 
                The minimum amounts of insurance coverage required under this
           paragraph 1 shall be per occurrence, combined single limit for all
           coverage required under this paragraph 1.

</TABLE>
 
             (ii) Subject to Section 17(b)(i) above, each carrier as appropriate
        shall cause the policies of insurance described in such Section 17(b)(i)
        to be duly and properly endorsed by that carrier's insurance
        underwriters as follows:
 
                1. as to the policies of insurance described in paragraphs
           (b)(i)1 and (b)(i)2 of Section 17:
 
                    (A) to provide that any waiver of rights of subrogration
               against other parties by one party will not affect the coverage
               provided thereunder with respect to the other party; and
 
                    (B) to provide that the one party's underwriters shall waive
               any and all subrogation rights against the other party, its
               directors, officers, agents, employees and other authorized
               representatives, except for gross negligence or wilful
               misconduct, with regard to any breach of warranty on the part of
               the other party or to provide other evidence of such waiver or
               recourse against the other party, its directors, officers,
               agents, employees and other authorized representatives.
 
                    (C) to provide that each party, its directors, officers,
               agents, employees and other authorized representatives shall be
               endorsed as named insured parties thereunder, except for gross
               negligence or wilful misconduct; and
 
                    (D) to provide that said insurance shall be primary
               insurance and to acknowledge that any other insurance policy or
               policies of each party shall be secondary or excess insurance.
 
                2. as to policies of insurance described in paragraph (b)(i)1 of
           Section 17 to provide a breach of warranty clause to said policies;
           and
 
             (iii) Each party shall cause each of the insurance policies
        referred to in Section 17(b)(i) to be duly and properly endorsed to
        provide that said policy or policies or any part or parts thereof shall
        not be canceled, terminated or materially altered, changed or amended by
        each party's insurance underwriters, until after 30 days' prior notice
        to the other party, such notice period to commence when such other party
        actually receives such notice.
 
             (iv) Simultaneously with the commencement of this Agreement, and
        from time to time thereafter upon request by either party, the other
        party shall furnish to the requesting party evidence reasonably
        satisfactory to the requesting party of the aforesaid insurance coverage
        and endorsements, including certificates certifying that the aforesaid
        insurance and endorsements are in full force and effect. Initially, this
        evidence shall be a certificate of insurance required hereunder.
 
             (v) In the event either party fails to maintain in full force and
        effect any of the insurance and endorsements required in terms of these
        sections, the other party shall have the right (but not the obligation)
        to procure and maintain such insurance or any part thereof. The cost of
        such insurance shall be payable by the first party to the other party
        upon demand by the other party. The procurement of such insurance or any
        part thereof by the other party shall not discharge or excuse the first
        party's obligation to comply with the provisions of Sections 17(b)(i)
        and 17(b)(ii)
 
          (c) Survival of Rights and Obligations.  The rights and obligations of
     Section 18(a) shall survive the expiration or termination of this
     Agreement.

     18. Term and Termination.
 
          (a) Term.  Unless the carriers agree to an earlier commencement date,
     the term of this Agreement shall commence as soon as practicable after the
     date that is the later of the date that this Agreement is signed by both
     parties or the date that the investment agreement between AWA and AmWest
     partners, L.P. (the "Investment Agreement") is consummated and shall
     continue until the date immediately preceding the tenth anniversary of the
     commencement date, unless earlier terminated as provided herein, and shall
     continue thereafter until either carrier gives the other carrier notice of
     termination at least 90 days prior to the effective date of such
     termination. In no event shall termination or expiration pursuant to this
     Section 18(a) be effective unless such 90 days' notice is provided.
 
          (b) Termination as a Result of Changes of Law.  In the event there is
     any change in treaties, statutes or regulations of air transportation that
     materially affects the rights and/or obligations presently in force with
     respect to the air transportation services of CAL or AWA or both, relating
     to CO* or HP* Flights, then the carriers will consult, within 30 days after
     any of the occurrences described herein, in order to determine or seek
     mutual agreement as to what, if any changes to this Agreement are necessary
     or appropriate, including but not limited to the early termination and
     cancellation of this Agreement.
 
          (c) Other Termination Rights.  In addition to any other provisions of
     this Agreement, this Agreement may be terminated, without liability, as
     follows:
 
             (i) By either carrier on 30 days' prior written notice, if the
        other carrier has breached any material provision of this Agreement
        unless such other carrier cures such breach within such 30 day period;
 
             (ii) By either carrier immediately on notice, if the other carrier
        shall be dissolved or shall fail to maintain its corporate existence in
        good standing, or shall have its authority to operate as a scheduled
        airline suspended or revoked, either in whole or with respect to the CO*
        or HP* Flights, or shall cease operations as a scheduled airline.
 
             (iii) By either carrier immediately on notice if the other carrier
        shall be cited by any government authority for any significant
        noncompliance with a material law, rule or regulation with respect to
        the marketing or operation of a CO* or HP* Flight;
 
             (iv) By either carrier immediately on notice, in the event that the
        commencement date of this Agreement is prior to the date that the
        Investment Agreement is consummated, if the Investment Agreement is
        terminated prior to its having been consummated;
 
             (v) Except for AWA's currently pending Chapter 11 proceeding, by
        either carrier if a petition is filed by or against the other carrier
        under bankruptcy law, or any other law providing for the relief of
        debtors, and the affected party does not succeed in having such petition
        lifted or stayed within sixty days from the date of entry; the carrier
        at its option may cancel this Agreement immediately and exercise such
        other remedies as may be available at law and/or in equity;
 
             (vi) By either carrier on six months' prior written notice, if a
        carrier, foreign or domestic, that competes with the terminating carrier
        on a material basis, acquires majority ownership of or substantial
        control over the other carrier.
 
             (vii) By CAL immediately on notice if
 
                1. AWA shall fail to maintain any of its aircraft in an
           airworthy condition and conduct its flight operations in accordance
           with the standards, rules and regulations promulgated by any
           government authority; or
 
                2. AWA shall have a completion factor of less then 80% during
           any 20 day period with respect to CO* Flights (including in such
           calculations all flights canceled less than one week prior to the
           date of its scheduled operation and excluding flights not completed
           due to weather or labor stoppages); and
 
                                        7
<PAGE>   8
 
             (viii) By AWA immediately on notice if
 
                1. CAL shall fail to maintain any of its aircraft in an
           airworthy condition and conduct its flight operations in accordance
           with the standards, rules and regulations promulgated by any
           government authority; or
 
                2. CAL shall have a completion factor of less then 80% during
           any 20 day period with respect to HP* Flights (including in such
           calculations all flights canceled less than one week prior to the
           date of its scheduled operation and excluding flights not completed
           due to weather or labor stoppages).
 
     19. Booking Fee.  The carrier operating over any segment of a Shared Code
Flight will be responsible for any booking fee relating to such segment charges
by the vendor of a computer reservation system used to create a booking on that
flight. If the booking fee relating to such segment is billed to the carrier
whose designator code is also used for that flight, the operating carrier will
reimburse the carrier whose designator code is also used for that flight.
 
     20. Entire Agreement, Waivers and Amendments.  This Agreement constitutes
the entire understanding of the carriers with respect to the subject matter
hereof superseding all prior discussions and agreements, written or oral. This
Agreement may not be amended, nor may any of its provisions be waived, except by
writing signed by both carriers. No delay on the part of either carrier in
exercising any right power or privilege hereunder shall operate as a waiver
hereof, nor shall any waiver operate as a continuing waiver of any right, power
or privilege.

     SECTION 5.03.  Delivery of Prospectuses.  If, and to the extent that, the
Company may be required by the 1933 Act or any other applicable Federal or state
law to furnish a prospectus to Warrant holders upon their exercise of Warrants,
the Company shall cause to be kept, either at the Warrant Agent's Office or at
such other location designated by the Company, sufficient quantities of such
prospectuses for delivery to Warrant holders upon their exercise of Warrants,
and shall deliver such prospectuses or cause such prospectuses to be delivered
to such Warrant holders together with the shares of Class B Common Stock or
other securities receivable by such Warrant holders upon their exercise of
Warrants.
 
                                   ARTICLE VI
 
                          CONCERNING THE WARRANT AGENT
 
     SECTION 6.01.  Payment of Certain Taxes.  The Company will from time to
time promptly pay all transfer, stamp or similar taxes and all other
governmental charges that may be imposed upon the Company or otherwise in
respect of the initial issuance or delivery of shares of Class B Common Stock
upon the exercise of Warrants, but the Company shall not be obligated to pay any
transfer, stamp or similar taxes or other governmental charges in respect of any
transfer of the Warrants or such shares effected by any holder thereof.
 
     SECTION 6.02.  Change of Warrant Agent.
 
          (a) The Warrant Agent, or any successor to it hereafter appointed, may
     resign its duties and be discharged from all further duties and liabilities
     hereunder (except liabilities arising as a result of the Warrant Agent's
     own negligence, willful misconduct or bad faith) after giving 60 days'
     notice in writing to the Company, except that such shorter notice may be
     given as the Company and AmWest shall, in writing, accept as sufficient. At
     least 15 days prior to the date such resignation is to become effective,
     the Warrant Agent shall cause a copy of such notice of resignation to be
     mailed to the registered holder of each Warrant Certificate. If the office
     of the Warrant Agent becomes vacant by resignation or incapacity to act or
     otherwise, the Company shall appoint a successor Warrant Agent in place of
     the Warrant Agent [; provided that in the event that AmWest is the holder
     of any Warrants at such time, the Company shall notify and consult with
     AmWest with respect to such proposed appointment]. If the Company shall
     fail to make such appointment within a period of 60 days after it has been
     notified in writing of such resignation or incapacity by the resigning or
     incapacitated Warrant Agent or by any holder of Warrants (who shall, with
     such notice, submit a copy of his Warrant Certificate for inspection by the
     Company), then the holder of any Warrants may apply, at the expense of the
     Company, to any court of competent jurisdiction for the appointment of a
     successor warrant agent.
 
          (b) The Warrant Agent may be removed by the Company at any time upon
     30 days' written notice to the Warrant Agent; provided, that the Warrant
     Agent shall not be removed until a successor Warrant Agent meeting the
     qualifications hereof shall have been appointed and provided further that
     in the event AmWest is the holder of any Warrants at such time, the Company
     shall obtain the consent of AmWest, which consent shall not be unreasonably
     withheld.
 
          (c) Any successor Warrant Agent, whether appointed by the Company or
     by a court, shall be a corporation organized, in good standing and doing
     business under the laws of the United States of America or any state
     thereof or the District of Columbia, and authorized under such laws to
     exercise corporate trust powers and subject to supervision or examination
     by Federal or state authority and having a combined capital and surplus of
     not less than $10,000,000. The combined capital and surplus of any such
     successor Warrant Agent shall be deemed to be the combined capital and
     surplus as set forth in the most recent report of its condition published
     prior to its appointment pursuant to law or to the requirements of a
     Federal or state supervising or examining authority. After appointment, any
     successor Warrant Agent shall be vested with all the authority, powers,
     rights, immunities, duties and obligations of its predecessor Warrant Agent
     with like effect as if originally named as Warrant Agent hereunder, without
     any further assurance, conveyance, act or deed; provided, however, that in
     no event shall any successor Warrant Agent be liable for any breach,
     default or failure of performance by the predecessor Warrant Agent of any
     covenant or obligation under this Agreement existing on the date the
     successor
 
                                       15
<PAGE>   3
 
     Warrant Agent assumes authority pursuant to this Section 6.02. If for any
     reason it becomes necessary or appropriate, the predecessor Warrant Agent
     shall execute and deliver, at the expense of the Company, an instrument
     transferring to such successor Warrant Agent all the authority, powers and
     rights of such predecessor Warrant Agent hereunder; and upon request of any
     successor Warrant Agent, the Company shall make, execute, acknowledge and
     deliver any and all instruments in writing to more fully and effectually
     vest in and confirm to such successor Warrant Agent all such authority,
     powers, rights, immunities, duties and obligations. Upon assumption by a
     successor Warrant Agent of the duties and responsibilities hereunder, the
     predecessor Warrant Agent shall deliver and transfer, at the expense of the
     Company, to the successor Warrant Agent any property at the time held by it
     hereunder. As soon as practicable after such appointment, the Company shall
     give notice thereof to the predecessor Warrant Agent, the registered
     holders of the Warrants and each transfer agent for the shares of its Class
     B Common Stock. Failure to give such notice, or any defect therein, shall
     not affect the validity of the appointment of the successor Warrant Agent.
 
          (d) Any corporation into which the Warrant Agent may be merged or with
     which it may be consolidated, or any corporation resulting from any merger
     or consolidation to which the Warrant Agent shall be a party, shall be the
     successor Warrant Agent under this Agreement without any further act,
     provided that such corporation is eligible for appointment as a successor
     to the Warrant Agent. Any such successor Warrant Agent shall promptly cause
     notice of its succession as Warrant Agent to be mailed to the Company and
     to the registered holder of each Warrant Certificate. In case at the time
     such successor Warrant Agent shall succeed to the agency created by this
     Agreement, any of the Warrant Certificates shall have been countersigned
     but not delivered, any such successor Warrant Agent may adopt the
     countersignature of the original Warrant Agent and deliver such Warrant
     Certificates so countersigned, and in case at that time any of the Warrant
     Certificates shall not have been countersigned, any successor to the
     Warrant Agent may countersign such Warrant Certificates either in the name
     of the predecessor Warrant Agent or in the name of the successor Warrant
     Agent; and in all such cases Warrant Certificates shall have the full force
     provided in the Warrant Certificates and in this Agreement.
 
          (e) In case at any time the name of the Warrant Agent shall be changed
     and at such time any of the Warrant Certificates shall have been
     countersigned but not delivered, the Warrant Agent may adopt the
     countersignatures under its prior name and deliver such Warrant
     Certificates so countersigned; and in case at that time any of the Warrant
     Certificates shall not have been countersigned, the Warrant Agent may
     countersign such Warrant Certificates either in its prior name or in its
     changed name; and in all such cases such Warrant Certificates shall have
     the full force provided in the Warrant Certificates and in this Agreement.
 
     SECTION 6.03.  Compensation; Further Assurances.  The Company agrees (i)
that it will pay the Warrant Agent the fees set forth in Exhibit B for its
services as Warrant Agent hereunder and, except as otherwise expressly provided,
will pay or reimburse the Warrant Agent upon demand for all reasonable expenses,
disbursements and advances incurred or made by the Warrant Agent in accordance
with any of the provisions of this Agreement (including the reasonable
compensation, expenses and disbursements of its agents and counsel) except any
such expense, disbursement or advance as may arise from its or any of their
negligence, willful misconduct or bad faith; and (ii) that it will perform,
execute, acknowledge and deliver or cause to be performed, executed,
acknowledged and delivered all such further and other acts, instruments and
assurances as may reasonably be required by the Warrant Agent for the carrying
out or performing of the provisions of this Agreement.
 
     SECTION 6.04.  Reliance on Counsel.  The Warrant Agent may consult with
legal counsel (who may be legal counsel for the Company), and the written
opinion of such counsel or any advice of legal counsel subsequently confirmed by
a written opinion of such counsel shall be full and complete authorization and
protection to the Warrant Agent as to any action taken or omitted by it in good
faith and in accordance with such written opinion or advice, provided that such
counsel shall be reasonably acceptable to the Company.
 
     SECTION 6.05.  Proof of Actions Taken.  Whenever in the performance of its
duties under this Agreement the Warrant Agent shall deem it necessary or
desirable that any matter be proved or established by
 
                                       16
<PAGE>   4
 
the Company prior to taking or suffering or omitting any action hereunder, such
matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of bad faith on the part of the Warrant Agent,
be deemed to be conclusively proved and established by an Officers' Certificate
delivered to the Warrant Agent; and such Officers' Certificate shall, in the
absence of bad faith on the part of the Warrant Agent be full authority to the
Warrant Agent for any action taken, suffered or omitted in good faith by it
under the provisions of this Agreement in reliance upon such certificate; but in
its discretion the Warrant Agent may in lieu thereof accept other evidence of
such fact or matter or may require such further or additional evidence as to it
may deem reasonable.
 
     SECTION 6.06.  Correctness of Statements.  The Warrant Agent shall not be
liable for or by reason of any of the statements of fact or recitals contained
in this Agreement or in the Warrant Certificates (except its countersignature
thereof) or be required to verify the same, and all such statements and recitals
are and shall be deemed to have been made by the Company only.
 
     SECTION 6.07.  Validity of Agreement.  The Warrant Agent shall not be under
any responsibility in respect of the validity of this Agreement or the execution
and delivery hereof (other than such execution and delivery by the Warrant
Agent) or in respect of the validity or execution of any Warrant Certificates
(except its countersignature thereof); nor shall it be responsible for any
breach by the Company of any covenant or condition contained in this Agreement
or in any Warrant Certificate; nor shall it by any act hereunder be deemed to
make any representation or warranty as to the authorization or reservation of
any shares of Class B Common Stock to be issued pursuant to this Agreement or
any Warrants or as to whether any shares of Class B Common Stock will, when
issued, be validly issued and fully paid and non-assessable.
 
     SECTION 6.08.  Use of Agents.  The Warrant Agent may execute and exercise
any of the rights or powers hereby vested in it or perform any duty hereunder
either itself or by or through its attorneys or agents and the Warrant Agent
shall not be responsible for the misconduct or negligence of any agent or
attorney, provided due care had been exercised in the appointment and continued
employment thereof.
 
     SECTION 6.09.  Liability of Warrant Agent.  The Warrant Agent shall incur
no liability or responsibility to the Company or to any holder of Warrants for
any action taken in reliance on any notice, resolution, waiver, consent, order,
certificate, or other paper, document or instrument believed by it to be genuine
and to have been signed, sent or presented by the proper party or parties. The
Company agrees to indemnify the Warrant Agent and hold it harmless against any
and all liabilities, including judgments, costs and reasonable counsel fees, for
anything done or omitted in good faith by the Warrant Agent in the execution of
this Warrant Agreement, except as a result of the Warrant Agent's negligence or
willful misconduct or bad faith.
 
     SECTION 6.10.  Legal Proceedings.  The Warrant Agent shall be under no
obligation to institute any action, suit or legal proceeding or to take any
other action likely to involve expense unless the Company or one or more holders
of Warrants shall furnish the Warrant Agent with reasonable security and
indemnity for any costs and expenses which may be incurred, but this provision
shall not affect the power of the Warrant Agent to take such action as the
Warrant Agent may consider proper, whether with or without any such security or
indemnity.
 
     SECTION 6.11.  Other Transactions in Securities of the Company.  The
Warrant Agent in its individual or any other capacity may become the owner of
the Warrants or other securities of the Company, or become pecuniarily
interested in any transaction in which the Company may be interested, or
contract with or lend money to the Company or otherwise act as fully and freely
as though it were not Warrant Agent under this Warrant Agreement. Nothing herein
shall preclude the Warrant Agent from acting in any other capacity for the
Company or for any other legal entity.
 
     SECTION 6.12.  Actions as Agent.  The Warrant Agent shall act hereunder
solely as agent and not in a ministerial capacity, and its duties shall be
determined solely by the provisions hereof. The Warrant Agent shall not be
liable for anything which it may do or refrain from doing in good faith in
connection with this Agreement except for its own negligence or willful
misconduct or bad faith.
 
     SECTION 6.13.  Appointment and Acceptance of Agency.  The Company hereby
appoints the Warrant Agent to act as agent for the Company in accordance with
the instructions set forth in this Agreement, and the
 
                                       17

     amendments with the Company for the purpose of evidencing the rights of
     Warrant holders upon consolidation, merger, sale, transfer,
     reclassification, liquidation or dissolution pursuant to Section 4.05
     hereof, making any changes or corrections in this Agreement that are
     required to cure any ambiguity, to correct or supplement any provision
     contained herein that may be defective or inconsistent with any other
     provision herein or any clerical omission or mistake or manifest error
     herein contained, or making such other provisions in regard to matters or
     questions arising under this Agreement as shall not adversely affect the
     interests of the holders of the Warrants or be inconsistent with this
     Agreement or any supplemental agreement or amendment.

number of the Warrants at the time outstanding, the Company and the Warrant
Agent may at any time and from time to time by supplemental agreement or
amendment add any provisions to or change in any manner or eliminate any of the
provisions of this Agreement or of any supplemental agreement or modify in any
manner the rights and obligations of the Warrant holders and of the Company;
provided, however, that no such supplemental agreement or amendment shall,
without the consent of the registered holder of each outstanding Warrant
affected thereby,
 
             (1) alter the provisions of this Agreement so as to affect
        adversely in any material respect the terms upon which the Warrants are
        exercisable; or

                   WARRANTS TO PURCHASE CLASS B COMMON STOCK
                         OF AMERICA WEST AIRLINES, INC.
 
     AMERICA WEST AIRLINES, INC., a Delaware corporation (hereinafter called the
("Company" ), for value received, hereby certifies that
 
                        or registered assigns, is the owner of the number of
Warrants set forth above, each of which represents the right, at any time
commencing on the day after             , 1994, and before 5:00 p.m., New York
time, on             , 1999, on which date such Warrants expire, initially to
purchase, subject to the terms hereof and of the Warrant Agreement (as
hereinafter defined), one share of Class B Common Stock, par value $[     ] per
share, of the Company (hereinafter called the "Class B Common Stock" ) at the
price of $[     ] per share (the "Warrant Price" ), subject to the terms and
conditions hereof and of the Warrant Agreement, each such purchase to be made,
and to be deemed effective for the purpose of determining the date of exercise,
only upon surrender hereof to the Company at the Warrant Agent's Office, with
the Election to Exercise Form on the reverse hereof duly completed and signed,
and upon [either (i)] payment in full to the Warrant Agent for the account of
the Company of the Warrant Price (a) in cash, (b) by certified or official bank
check, or (c) by any combination of the foregoing [or (ii) payment in full to
the Warrant Agent as provided pursuant to the last sentence of Section 3.02(c)
of the Warrant Agreement], and upon compliance with and subject to the
conditions set forth herein and in the Warrant Agreement. Capitalized terms that
are not otherwise defined herein shall have the meanings ascribed to them in the
Warrant Agreement (as hereinafter defined).
 
     The Warrant Price and, at the Company's option, either (1) the number of
shares of Class B Common Stock purchasable on the exercise of each Warrant or
(2) the number of Warrants outstanding, are subject to adjustment in certain
events as provided in the Warrant Agreement. In the event the Company elects to
adjust the number of Warrants outstanding rather than the number of shares of
Class B Common Stock purchasable on the exercise of each Warrant, the Company
shall cause the Warrant Agent to distribute to registered holders of Warrant
Certificates either Warrant Certificates representing any additional Warrants
issuable pursuant to the adjustment or substitute Warrant Certificates to
replace all outstanding Warrant Certificates in accordance with the provisions
of the Warrant Agreement. The Company shall not be required to issue fractions
of Warrants or Warrant Certificates evidencing fractional Warrants upon any such
adjustment or otherwise, but the Company shall make adjustment in cash or scrip
for any fraction of a Warrant which the registered holder of Warrants would have
been entitled to receive upon such adjustment or otherwise on the basis of the
then-current market value of such fraction of a Warrant (computed as provided in
the Warrant Agreement).
 
     This Warrant Certificate is issued under and in accordance with the Warrant
Agreement dated as of [            ], 1994 (herein called the "Warrant
Agreement" ), between the Company and the Warrant Agent and is subject to and is
to be construed in accordance with the terms and provisions of the Warrant

Agreement, which terms and provisions are hereby incorporated by reference
herein and made a part hereof. Every holder of this Warrant Certificate consents
to all of the terms contained in the Warrant Agreement by acceptance hereof. A
copy of the Warrant Agreement is available for inspection by the registered
holder hereof at the Warrant Agent's Office.
 
     The Company shall not be required upon the exercise of the Warrants
represented hereby to issue fractions of shares of Class B Common Stock, to
distribute stock certificates that evidence fractional shares of Class B Common
Stock or to issue Warrant Certificates representing fractional Warrants, but
shall make adjustment in cash or scrip for any fraction of a share which the
same registered holder of Warrants exercised in the same transaction would have

the transferor is less than twice the total number of shares of Class A Common
beneficially owned by the transferor; provided, however, that nothing contained

and any Affiliate of AmWest or such partners who hold or receive shares of the
Company or direct the voting of any shares held by AmWest, and upon any
assignees or transferees in a single transaction or a related series of
transactions of all or substantially all of the Common Stock owned by AmWest or
any of its partners or Affiliates of AmWest or any of their partners; except

held by it in a single transaction or a related series of transactions, except

parties hereto that it accepts and is bound and subject to the terms of this
Agreement.

("Regulation 13D-G") under the Securities Exchange Act of 1934 (as amended, the
"Exchange Act"), and shall amend such filing as required by Regulation 13D-G.
Each other party hereto covered by such filing covenants and agrees to promptly
provide to AmWest all information pertaining to such party and necessary to make
such amendments and to notify AmWest of any changes in facts or circumstances
pertaining to such party that would require any amendments under Regulation
13D-G.
 
     4.5 AmWest agrees that it shall not cause any amendment to the provisions
of the Restated Certificate of Incorporation or the Bylaws or otherwise take any
action that supersedes or materially adversely affects or impairs the rights and
obligations of the parties under this Agreement or is contrary to the provisions
of this Agreement.
 
     4.6 (a) Each certificate evidencing shares of Common Stock issued to AmWest
or any of its partners, GPA and any of their respective Affiliates, and any
assignee or transferee bound by the terms hereof, including shares of Common

        WHICH ARE ON FILE AT THE PRINCIPAL OFFICE OF AMERICA WEST
        AIRLINES, INC.
 
and each such certificate, for so long as such certificate is held by AmWest or
any of its partners and any of their respective Affiliates and any assignee or
transferee bound by the terms hereof and prior to the termination or expiration
of this Agreement, shall include in such legend the following:
 
        THIS CERTIFICATE AND ANY INTEREST HEREIN MAY NOT BE SOLD,
        TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN ACCORDANCE WITH
        THE AFORESAID STOCKHOLDERS' AGREEMENT.
 
          (b) All certificates evidencing shares of Common Stock and warrants of
     the Company that have not been registered pursuant to the Securities Act of
     1933, as amended, and that are not exempt from registration under Section
     1145 of the Bankruptcy Code, shall at all times be conspicuously stamped or
     marked with a legend including substantially as follows:
 
        THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN

        THE SECURITIES LAWS OF ANY STATE; AND SUCH SECURITIES MAY NOT BE
        SOLD OR TRANSFERRED OTHER THAN IN ACCOR-
 
                                        6
<PAGE>   20
 
          DANCE WITH THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OR AN
          EXEMPTION THEREFROM AND FROM ANY APPLICABLE STATE SECURITIES LAWS.
 
          (c) Upon the termination of this Agreement, the Company shall, without
     charge and upon surrender of certificates by the holders thereof and
     written request cancel all certificates evidencing shares of Common Stock
     bearing the legend described in subparagraph (a) above and issue to the
     holders thereof replacement certificates that do not bear such a legend for
     an equal number of shares held by such holders. Upon the transfer of any
     Common Stock bearing the legend described in subparagraph (a) above to a
     party not bound by and subject to this Agreement, the Company shall,
     without charge and upon the surrender of certificates by the holders
     thereof and written request cancel all certificates evidencing such shares
     of Common Stock and issue to the transferee thereof replacement
     certificates that do not bear such a legend.
 
     4.7 During the term of this Agreement, AmWest shall not cause the issuance
of any preferred stock that would (a) increase the number of directors in excess
of the number provided in Section 2.1 (except for increases caused by a
provision allowing holders of preferred stock to elect additional directors in
the event of nonpayment of dividends) or (b) eliminate or reduce the number of
Creditors' Committee Directors, Equity Committee Director, Independent Company
Director, or GPA Director.
 
5. RIGHTS UPON BREACH.
 
     5.1 Each party hereto recognizes and agrees that a violation of any term,
provision, or condition of this Agreement may cause irreparable damage to the
other parties which is difficult or impossible to quantify or ascertain and that
the award of any sum of damages may not be adequate relief to such other
parties. Each party hereto therefore agrees that in the event of any breach of
this Agreement, the other party or parties shall, in addition to any remedies at
law which may be available, have the right to obtain appropriate equitable
(including, but not limited to, injunctive) relief. All remedies hereunder shall
be cumulative and not exclusive.
 
     5.2 In addition to any other remedies available at law or in equity, each
party hereto agrees that the Company shall have the right (a) to withhold
transfer, and to instruct any transfer agent for securities of the Company to
withhold transfer, of any certificates evidencing shares of Common Stock held by
AmWest or any partner or Affiliate of AmWest or transferee if the Company
reasonably believes that such transfer would not be in material compliance with
the terms and provisions of this Agreement, unless the transferee provides to
the Company an opinion of legal counsel reasonably acceptable to the Company
that such transfer will be in material compliance with the terms and provisions
hereof, and (b) to require any person requesting such transfer to provide such
information as may reasonably be requested by the Company regarding ownership of
securities, affiliations, if any, between AmWest and the transferee and such
other matters pertaining to the transfer as may be appropriate to enable the
Company to determine the compliance of the proposed transfer of securities with
the terms and provisions of this Agreement.
 
6. TERMINATION.
 
     6.1 This Agreement shall automatically terminate without any action by any
party on the day immediately preceding the Third Annual Meeting and shall not be
extended except in accordance with Section 7.3. Upon such termination, the
rights and obligations of each party hereunder shall terminate and the
provisions of this Agreement shall be of no force and effect; provided that no
such termination shall relieve any person or entity from liability for breach or
default of this Agreement prior to such termination.
 
     6.2 GPA's rights and obligations under this Agreement (other than its
obligations under Section 2.1(g)) shall terminate immediately and without notice
upon the earlier of (a) termination of this Agreement under Section 6.1, (b) the
sale or transfer by GPA of equity securities of the Company resulting in the
holding by GPA of less than two percent (2%) of the voting equity securities of
the Company (on a fully diluted basis), or (c) any occurrence, other than as
described in clause (b) above, resulting in the holding by GPA of less than two
percent (2%) of the voting equity securities of the Company (on a fully diluted
basis) if (i) the Company files a Form 10-Q under the Exchange Act, or other
written report or statement, that is delivered to
 
                                        7
<PAGE>   21
 
GPA and a copy to the party designated in Section 7.1, reflecting information as
to the Company's total issued and outstanding capital stock as of a date therein
specified (the "Determination Date") from which GPA can determine whether it
holds less than two percent (2%) of the voting equity securities of the Company
(on a fully diluted basis) and (ii) GPA fails to acquire (by purchase, or
otherwise) sufficient voting equity securities of the Company such that it
continues to hold less than two percent (2%) of the voting equity securities of
the Company (on a fully diluted basis) determined as of the Determination Date
for thirty-five (35) days after delivery of such Form 10-Q, or provision of such
report or statement to GPA. GPA acknowledges that the Company's continuing with
its existing procedures for the distribution of Form-10Qs constitutes delivery
to GPA within the meaning of this Section 6.2.

     forty-five (45) days) in which such registration would require the Company

     of the Company shall have determined in good faith is not in the best
     interests of the Company and its stockholders; or (iii) during any period
     (not to exceed forty-five (45) days) if each of the Company, Investor and
     each Fidelity Fund agrees in writing to suspend such registration for such

     terms appropriate for such a transaction and (ii) the managing underwriter
     of such underwritten offering shall inform the Company and the Requesting
     Holder by letter of its belief that the amount of securities requested to
     be included in such registration exceeds the amount which can be sold in
     (or during the time of) such offering within a price range acceptable to
     the Requesting Holder, then the Company will include in such registration
     such amount of securities which the Company is so advised can be sold in
     (or during the time of) such offering as follows: first, such Registrable
     Securities requested to be included in such registration by the Requesting
     Holder, its Affiliates and any direct or indirect transferees of its

        2.3 Piggyback Registration.
 
          (a) Right to Include Registrable Securities.  If the Company at any
     time proposes to register any of its equity securities under the Securities
     Act (other than by a registration on Form S-4 or Form S-8 or any successor
     or similar form then in effect and other than pursuant to Section 2.1 or
     2.2) in a form and in a manner that would permit registration of the
     Registrable Equity Securities, whether or not for sale for its own account,
     it will give prompt (but in no event less than [thirty (30)] days prior to
     the proposed date of filing the registration statement relating to such
     registration) notice to all Holders of Registrable Equity Securities of the
     Company's intention to do so and of such Holders' rights under this Section
     2.3. Upon the request of any such Holder made within [twenty (20)] days
     after the receipt by such Holder of any such notice (which request shall
     specify the Registrable Equity Securities intended to be disposed of by
     such Holder and the intended method or methods of disposition thereof) (the
     "Piggyback Registration Notice"), the Company will use [commercially
     reasonable] [its best] efforts to effect the registration under the
     Securities Act of all Registrable Equity Securities which the Company has
     been so requested to register by the Holders thereof, to the extent
     required to permit the disposition (in accordance with the intended method
     or methods thereof as aforesaid) of the Registrable Equity Securities so to
     be registered, provided that if, at any time after giving notice of its
     intention to register any equity securities and prior to the effective date
     of the registration statement filed in connection with such registration,
     the Company shall determine for any reason not to register or to delay
     registration of such equity securities, the Company may, at its election,
     give notice of such determination to each such Holder and, thereupon, (i)
     in the case of a determination not to register, shall be relieved of its
     obligation to register any
 
                                        5

     the right of Investor to request that such registration be effected as a
     registration under Section 2.2, and (ii) in the case of a determination to
     delay registering, shall be permitted to delay registering any Registrable
     Equity Securities for the same period as the delay in registering such
     other equity securities. No registration effected under this Section 2.3
     shall be deemed to have been effected pursuant to Section 2.1 or 2.2 or
     shall relieve the Company of its obligation to effect any registration
     under such Sections.
 
          (b) Priority in Piggyback Registrations.  If (i) a registration
     pursuant to this Section 2.3 involves an underwritten offering of the
     securities being registered, whether or not for sale for the account of the
     Company, to be distributed (on a firm commitment basis) by or through one
     or more underwriters of recognized standing under underwriting terms
     appropriate for such a transaction and (ii) the managing underwriter of
     such underwritten offering shall inform the Company and the Holders
     requesting such registration by letter of its belief that the amount of
     securities requested to be included in such registration exceeds the amount
     which can be sold in (or during the time of) such offering within a price
     range acceptable to the Company, then the Company will include in such
     registration such amount of securities which the Company is so advised can
     be sold in (or during the time of) such offering as follows: first, all
     securities proposed by the Company to be sold for its own account; second,
     such Registrable Equity Securities requested to be included in such
     registration by Investor, any Fidelity Fund or any of their respective
     Affiliates pro rata on the basis of the amount of such securities so
     proposed to be sold and so requested to be included by such parties; third,
     such Registrable Equity Securities requested to be included in such
     registration by all other Holders pro rata on the basis of the amount of
     such securities so proposed to be sold and so requested to be included by

     such securities so proposed to be sold and so requested to be included.

     registration to permit the sale of the Notes thereunder in accordance with
     the intended method or methods of disposition thereof. If notified by a

     to this Agreement shall be permitted to withdraw all or part of its
     Registrable Securities from such registration at any time prior to the

     provided that, in the event of a withdrawal from a registration effected
     pursuant to Section 2.2, such registration shall be deemed to have been
     effected for purposes of Section 2.5(c) unless (i) the Requesting Holder
     and any Participating Holders shall have paid or reimbursed the Company for
     the reasonable fees and expenses paid by the Company hereunder to the
     extent such fees and expenses would customarily have been paid by sellers
     in connection with a registration of similar securities or (ii) the
     Requesting Holder elects to terminate such registration due to the
     occurrence of a Material Adverse Change; provided, however, that only one

        in no event later than ten (10) days prior to such filing), the Company
        will furnish to the Participating Holders or their counsel copies of
        reasonably complete drafts of all such documents proposed to be filed
        (excluding exhibits, which shall be made available upon request by any
        Participating Holder), and any such Holder shall have the opportunity to
        object to any information contained therein and the Company will make
        the corrections reasonably requested by such Holder with respect to such
        information prior to filing any such registration statement, amendment,

        request relates to information with respect to such Holder) and (B) as
        may be necessary to keep such registration statement effective for the
        period referred to in Section 2.1(b) in the case of a Shelf Registration
        Statement or [nine (9) months] in the case of a registration effected
        pursuant to Section 2.2 or 2.3 (or such shorter period as shall be
        necessary to complete the distribution of the securities covered
        thereby, but not before the expiration of the applicable period referred
        to in Section 4(3) of the Securities Act and Rule 174 thereunder), and
        comply with the provisions of the

        (in each case including all exhibits and documents incorporated by
        reference), such number of copies of the prospectus contained in such
        registration statement (including each preliminary prospectus and any
        summary prospectus) and any other prospectus filed under Rule 424 under
        the Securities Act relating to such Holder's Registrable Securities, in
        conformity with the requirements of the Securities Act, and such other
        documents as such Holder, underwriter or agent may reasonably request to
        facilitate the disposition of such Registrable Securities;
 
             (iv) use [commercially reasonable] [its best] efforts to register
        or qualify all Registrable Securities and other securities covered by
        such registration statement under (A) with respect to the Shelf

        statement remains in effect, and take any other action which may be
        reasonably necessary or advisable to enable such Holder to consummate
        the disposition of the securities owned by such Holder, except that the
        Company shall not for any such purpose be required to (a) qualify

        wherein it would not but for the requirements of this clause (iv) be
        obligated to be so qualified, (b) subject itself to taxation in any such

             (v) use [commercially reasonable] [its best] efforts to cause all
        Registrable Securities covered by such registration statement to be
        registered with or approved by such other governmental agencies or
        authorities applicable to the Company as may be reasonably necessary to
        enable the seller or sellers thereof (or underwriter or agent, if any)
        to consummate the disposition of such Registrable Securities in
        accordance with the plan of distribution set forth in such registration
        statement;
 
             (vi) furnish to each Holder of at least   percent (   %) in
        interest of Registrable Equity Securities or at least   percent (   %)
        in aggregate principal amount of Registrable Debt Securities covered by
        such registration statement a signed counterpart, addressed to such

           includes an underwritten public offering, dated the date of the
           closing under the underwriting agreement), and
 
                (B) a "comfort" letter, dated the effective date of such
           registration statement (and, if such registration includes an
           underwritten public offering, dated the date of the closing under the
           underwriting agreement), signed by the independent public accountants
           who have certified the Company's financial statements included in
           such registration statement,
 
        in each case, reasonably satisfactory in form and substance to such
        Holder (and underwriter or agent and their respective counsel) and
        covering substantially the same matters with respect to such
        registration statement (and the prospectus included therein) and, in the
        case of the accountants' letter, with respect to events subsequent to
        the date of such financial statements, as are customarily covered in
        opinions of issuer's counsel and in accountants' letters delivered to
        the underwriter or agent in underwritten public offerings of securities;
 
             (vii) promptly notify each Holder and any underwriter or agent
        participating in the disposition of Registrable Securities covered by
        such registration statement, at any time when a prospectus relating
        thereto is required to be delivered under the Securities Act, upon
        discovery that, or upon the
 
                                        8
<PAGE>   35
 
          happening of any event known to the Company as a result of which, the
          prospectus included in such registration statement, as then in effect,
          includes an untrue statement of a material fact or omits to state any
          material fact required to be stated therein or necessary to make the
          statements therein not misleading in light of the circumstances under
          which they were made, and promptly prepare and furnish to such Holder
          (or underwriter or agent, if any) a reasonable number of copies of a
          supplement to or an amendment of such prospectus as may be necessary
          so that, as thereafter delivered to the purchasers of such securities,
          such prospectus shall not include an untrue statement of a material
          fact or omit to state a material fact required to be stated therein or
          necessary to make the statements therein not misleading in light of
          the circumstances under which they were made;
 
             (viii) otherwise use [commercially reasonable] [its best] efforts
        to comply with all applicable rules and regulations of the SEC, and make
        available to its security holders, as soon as reasonably practicable
        (but not more than fifteen (15) months) after the effective date of the
        registration statement, an earnings statement satisfying the provisions
        of Section 11(a) of the Securities Act and Rule 158 promulgated
        thereunder, and furnish to each Holder covered by such registration
        statement or any participating underwriter or agent at least five (5)
        business days prior to the filing a copy of any amendment or supplement
        to such registration statement or prospectus;
 
             (ix) provide and cause to be maintained a transfer agent and
        registrar for all Registrable Securities covered by such registration
        statement from and after a date not later than the effective date of
        such registration statement;
 
             (x) use [commercially reasonable] [its best] efforts to (A) list,
        on or prior to the effective date of such registration statement, all
        Registrable Equity Securities covered by such registration statement on
        any securities exchange on which any of the Registrable Equity
        Securities is then listed, if any or (B) have authorized for quotation
        and/or listing, as applicable, on the National Association of Securities
        Dealers, Inc. Automated Quotation ("NASDAQ") of the National Market

             (xi) cooperate with each seller of Registrable Securities and each
        underwriter or agent participating in the disposition of such
        Registrable Securities and their respective counsel in connection with
        any filings required to be made with the National Association of
        Securities Dealers;
 
             (xii) use [commercially reasonable] [its best] efforts to prevent
        the issuance by the SEC or any other governmental agency or court of a
        stop order, injunction or other order suspending the effectiveness of
        such registration statement and, if such an order is issued, use
        [commercially reasonable] [its best] efforts to cause such order to be
        lifted as promptly as practicable;
 
             [(xiii) enter into such agreements and take such other actions as
        the Requisite Holders of such Registrable Securities shall reasonably
        request in order to expedite or facilitate the disposition of such
        Registrable Securities;]
 
             (xiv) promptly notify each seller and the underwriter or agent, if
        any:
 
                (A) when such registration statement or any prospectus used in
           connection therewith, or any amendment or supplement thereto, has
           been filed and, with respect to such registration statement or any
           post-effective amendment thereto, when the same has become effective;

                (C) of the notification to the Company by the SEC of its
           initiation of any proceeding with respect to, or of the issuance by
           the SEC of, any stop order suspending the effectiveness of such
           registration statement; and
 
                                        9
<PAGE>   36
 
                (D) of the receipt by the Company of any notification with
           respect to the suspension of the qualification of any Registrable
           Securities for sale under the applicable securities or blue sky laws
           of any jurisdiction;
 
             (xv) cooperate with each seller of Registrable Securities and each
        underwriter or agent participating in the distribution of such
        Registrable Securities to facilitate the timely preparation and delivery
        of certificates (which shall not bear any restrictive legends, other
        than as required by applicable law, the Investment Agreement or the Note
        Purchase Agreement) representing securities sold under a registration
        statement hereunder, and enable such securities to be in such
        denominations and registered in such names as such seller, underwriter
        or agent may request and keep available and make available to the
        Company's transfer agent, prior to the effectiveness of such
        registration statement, an adequate supply of such certificates;
 
             (xvi) not later than the effective date of such registration
        statement, provide a CUSIP number for all Registrable Securities covered
        by a registration statement hereunder;
 
             (xvii) incorporate in the registration statement or any amendment,
        supplement or post-effective amendment thereto such information as each
        Holder, the underwriter or agent (if any) or their respective counsel
        may reasonably request to be included therein with respect to any
        Registrable Securities being sold by such Holder to such underwriter or
        agent, the purchase price being paid therefor by such underwriter or
        agent and any other terms of the offering of such Registrable
        Securities;
 
             (xviii) during any period when a prospectus is required to be
        delivered under the Securities Act, make periodic filings with the SEC
        pursuant to and containing the information required by the Exchange Act
        (whether or not the Company is required to make such filings pursuant to
        such Act);
 
             (xix) in connection with an underwritten offering, participate, to
        the extent reasonably requested by the Requisite Holders or the managing
        underwriter for the offering, in customary efforts to sell the
        securities under the offering, including, without limitation,
        participating in "road shows."
 
          (h) Agreements of Certain Holders.  (i) Each Holder of Registrable
     Securities as to which any registration is being effected shall furnish to
     the Company such information regarding such Holder, the Registrable
     Securities held by such Holder and the intended plan of distribution of
     such securities as the Company may from time to time reasonably request in
     writing in connection with such registration. If any registration statement
     refers to Investor, any Fidelity Fund or any of their respective Affiliates
     by name or otherwise as the holder of any securities of the Company, then
     such Holder shall have the right to require [(A) the insertion therein of
     language, in form and substance reasonably satisfactory to such Holder, to
     the effect that the holding by such Holder of such securities is not to be
     construed as a recommendation by such Holder of the investment quality of
     the Company's securities covered thereby and that such holding does not
     imply that such Holder will assist in meeting any future financial
     requirements of the Company, or (B)] in the event that such reference to
     such Holder by name or otherwise is not required by the Securities Act or
     any similar federal or state blue sky statute and the rules and regulations
     thereunder then in force, the deletion of the reference to such Holder.
 
          (ii) Each Holder of Registrable Securities as to which any
     registration is being effected agrees, by acquisition of such Registrable
     Securities, that upon receipt of any notice (a "Suspension Notice") from
     the Company of the happening of any event of the kind described in clause
     (vii) of Section 2.5(g), such Holder will forthwith discontinue such
     Holder's disposition of Registrable Securities pursuant to the registration
     statement relating to such Registrable Securities until such Holder's
     receipt of the copies of the supplemented or amended prospectus
     contemplated by clause (vii) of Section 2.5(g)[; provided, however, that in
     no event shall the period (the "Suspension Period") from the date on which
     such Holder receives a Suspension Notice to and including the date on which
     such Holder receives copies of the supplemented or amended prospectus
     contemplated by clause (vii) of Section 2.5(g) exceed twenty (20) days].
     The Company shall [use commercially reasonable efforts to] take such
     actions as are necessary to
 
                                       10
<PAGE>   37
 
     end the Suspension Period as promptly as practicable. In the event the
     Company shall give any such notice, the period referred to in clause (ii)
     of Section 2.5(g) shall be extended by a number of days equal to the number
     of days of the Suspension Period.
 
     2.6 Underwritten Offerings.
 
          (a) Underwritten Offerings in Connection with a Shelf or a Demand
     Registration.  If requested by the underwriters for any underwritten
     offering in connection with a registration pursuant to Section 2.1 or 2.2,
     the Company will enter into an underwriting agreement with such
     underwriters for such offering, such agreement (i) to be satisfactory in
     substance and form to the Company and to each of Investor and each Fidelity
     Fund (so long as it or any of its Affiliates holds Registrable Securities
     to be included in such registration) and (ii) to contain such
     representations and warranties by the Company and such Holders (subject to
     the last sentence of this Section 2.6(a)) and such other terms as are
     generally prevailing in agreements of such type, including, without
     limitation, indemnities to the effect and to the extent provided in Section
     2.8. Each of Investor and each Fidelity Fund (so long as it or any of its
     Affiliates holds Registrable Securities to be included in such
     registration) shall be a party to such underwriting agreement and may, at
     its option, require that any or all of the representations and warranties
     by, and the other agreements on the part of, the Company to and for the
     benefit of such underwriters shall also be made to and for its benefit and
     that any or all of the conditions precedent to the obligations of such
     underwriters under such underwriting agreement be conditions precedent to
     its obligations thereunder. [No Holder shall be required to make any
     representations or warranties to or agreements with the Company or the
     underwriters other than representations, warranties or agreements regarding
     such Holder's Registrable Securities and such Holder's intended method of
     distribution and any other representation required by law.]
 
          (b) Underwritten Offerings in Connection with Piggyback
     Registrations.  If the Company at any time proposes to register any of its
     equity securities under the Securities Act as contemplated by Section 2.3
     and such securities are to be distributed by or through one or more
     underwriters, the Company will, if requested by any Participating Holder
     and subject to Section 2.3(b), arrange for such underwriters to include all
     of the Registrable Equity Securities to be offered and sold by such Holder
     or Holders among the securities to be distributed by such underwriters. The
     Holders of Registrable Equity Securities to be distributed by such
     underwriters shall be parties to the underwriting agreement between the
     Company and such underwriters, provided that such agreement is reasonably
     satisfactory in substance and form to the Requisite Holders, and may, at
     their option, require that any or all of the representations and warranties
     by, and the other agreements on the part of, the Company to and for the
     benefit of such underwriters shall also be made to and for the benefit of
     such Holders and that any or all of the conditions precedent to the
     obligations of such underwriters under such underwriting agreement be
     conditions precedent to the obligations of such Holders thereunder. Any
     such Holder shall not be required to make any representations or warranties
     to or agreements with the Company or the underwriters other than
     representations, warranties or agreements regarding such Holder, such
     Holder's Registrable Equity Securities and such Holder's intended method of
     distribution and any other representation required by law.
 
     2.7 Preparation; Reasonable Investigation.  In connection with the
preparation and filing of each registration statement under the Securities Act
pursuant to this Agreement, the Company will give the Holders of Registrable
Securities to be registered under such registration statement, their
underwriters or agents, if any, and their respective counsel and accountants
reasonable access to its books and records and such opportunities to discuss the
business of the Company with its officers and the independent public accountants
who have certified its financial statements as shall be necessary, in the
opinion of such Holders' and such underwriters' or agents' respective counsel,
to conduct a reasonable investigation within the meaning of the Securities Act.
 
     2.8 Indemnification.
 
          (a) Indemnification by the Company.  The Company agrees to indemnify
     and hold harmless, to the full extent permitted by law, each Holder
     participating in an offering hereunder, its directors, officers,
 
                                       11
<PAGE>   38
 
     shareholders, employees, investment advisers, agents and Affiliates, either
     direct or indirect (and such Affiliates', directors, officers,
     shareholders, employees, investment advisers and agents), and each other
     Person, if any, who controls such Persons within the meaning of the
     Securities Act (each such Person, an "Indemnified Party"), from and against
     any losses, claims, damages, liabilities or expenses, joint or several
     (each a "Loss" and collectively, "Losses"), to which such Indemnified Party
     may become subject under the Securities Act or otherwise, insofar as such
     Losses (or actions or proceedings, whether commenced or threatened, in
     respect thereof) arise out of or are based upon any untrue statement or
     alleged untrue statement of any material fact contained in any registration
     statement under which such securities were registered under the Securities
     Act (including all documents incorporated therein by reference), any
     preliminary prospectus, final prospectus or summary prospectus contained
     therein, or any amendment or supplement thereto, or any omission or alleged
     omission to state therein a material fact required to be stated therein or
     necessary to make the statements therein not misleading, and the Company
     will reimburse such Indemnified Party for any legal or any other expenses
     reasonably incurred by it in connection with investigating or defending
     against any such Loss, action or proceeding; provided that in any such case
     the Company shall not be liable to any particular Indemnified Party to the
     extent that such Loss (or action or proceeding in respect thereof) arises
     out of or is based upon an untrue statement or alleged untrue statement or
     omission or alleged omission made in such registration statement, any such
     preliminary prospectus, final prospectus, summary prospectus, amendment or
     supplement in reliance upon and in conformity with written information
     furnished to the Company through an instrument duly executed by such
     Indemnified Party specifically for inclusion therein; and provided,
     further, that the Company shall not be liable in any such case to the
     extent it is finally determined by a court of competent jurisdiction that
     any such Loss (or action or proceeding in respect thereof) arises out of or
     is based upon an untrue statement or alleged untrue statement or omission
     or alleged omission made
 
             (i) in any such preliminary prospectus, if (A) it was the
        responsibility of such Indemnified Party to provide the Person asserting
        such Loss with a current copy of the prospectus and such Indemnified
        Party failed to deliver or cause to be delivered a copy of the
        prospectus to such Person after the Company had furnished such
        Indemnified Party with a sufficient number of copies of the same prior
        to the sale of Registrable Securities to the Person asserting such Loss
        and (B) the prospectus corrected such untrue statement or omission; or
 
             (ii) in such prospectus, if such untrue statement or omission is
        corrected in an amendment or supplement to such prospectus and such
        amendment or supplement has been delivered to the Indemnified Party
        prior to the sale of Registrable Securities to the Person asserting such
        Loss and the Indemnified Party thereafter fails to deliver the
        prospectus as so amended or supplemented prior to or concurrently with
        such sale after the Company had furnished such Indemnified Party with a
        sufficient number of copies of the same [and informed the Indemnified
        Party of the necessity to deliver such amendment or supplement to
        purchasers of securities].
 
     Such indemnity shall remain in full force and effect regardless of any
     investigation made by or on behalf of such Indemnified Party and shall
     survive the transfer of such securities by such Indemnified Party. The
     Company shall also indemnify each other Person who participates (including
     as an underwriter) in the offering or sale of Registrable Securities
     hereunder, their officers and directors and each other Person, if any, who
     controls any such participating Person within the meaning of the Securities
     Act to the same extent as provided above with respect to Indemnified
     Parties.
 
          (b) Indemnification by the Sellers.  The Company may require, as a
     condition to including any Registrable Securities in any registration
     statement filed pursuant to Section 2.3 and as a condition to indemnifying
     such sellers pursuant to this Section 2.8, that the Company shall have
     received an undertaking reasonably satisfactory to it from each prospective
     seller of such securities, to indemnify and hold harmless (in the same
     manner and to the same extent as set forth in paragraph (a) of this Section
     2.8) the Company, each director, officer, employee and agent of the
     Company, and each other Person, if any, who controls the Company within the
     meaning of the Securities Act, from and against any Losses (or actions or
     proceedings, whether commenced or threatened, in respect thereof) arising
     out of or
 
                                       12
<PAGE>   39
 
     based upon any untrue statement or alleged untrue statement of a material
     fact contained in any registration statement under which such securities
     were registered under the Securities Act (including all documents
     incorporated therein by reference), any preliminary prospectus, final
     prospectus or summary prospectus contained therein, or any amendment or
     supplement thereto, or any omission or alleged omission from such
     registration statement, preliminary prospectus, final prospectus or summary
     prospectus, or any amendment or supplement thereto required to be stated
     therein or necessary to make the statements therein not misleading, if (but
     only if) such untrue statement or alleged untrue statement or omission or
     alleged omission was made in reliance upon and in conformity with written
     information furnished to the Company through an instrument duly executed by
     such prospective seller specifically for inclusion therein; provided,
     however, that such prospective seller shall not be obligated to provide
     such indemnity to the extent that such Losses result, directly or
     indirectly, from the failure of the Company to promptly amend or take
     action to correct or supplement any such registration statement,
     prospectus, amendment or supplement based on corrected or supplemental
     information provided in writing by such prospective seller to the Company
     expressly for such purpose; and provided further, that the obligation to
     provide indemnification pursuant to this Section 2.8(b) shall be several,
     and not joint and several, among such indemnifying parties. Notwithstanding
     anything in this Section 2.8(b) to the contrary, in no event shall the
     liability of any prospective seller under such indemnity be greater in
     amount than the amount of the proceeds received by such seller upon the
     sale of its Registrable Securities in the offering to which the Losses
     relate. Such indemnity shall remain in full force and effect, regardless of
     any investigation made by or on behalf of the Company or any such director,
     officer, employee, agent or participating or controlling Person and shall
     survive the transfer of such securities by such prospective seller.
 
          (c) Notices of Claims, etc.  Promptly after receipt by an indemnified
     party of notice of the commencement of any action or proceeding involving a
     claim referred to in paragraph (a) or (b) of this Section 2.8, such
     indemnified party will, if a claim in respect thereof is to be made against
     an indemnifying party, give prompt written notice to the latter of the
     commencement of such action, provided that the failure of any indemnified
     party to give notice as provided herein shall not relieve the indemnifying
     party of its obligations under this Section 2.8, except to the extent that
     the indemnifying party is actually and materially prejudiced by such
     failure to give notice. In case any such action is brought against an
     indemnified party, the indemnifying party shall be entitled to participate
     in and to assume the defense thereof [(such assumption to constitute its
     acknowledgement of its agreement to indemnify the indemnified party with
     respect to such matters)], jointly with any other indemnifying party
     similarly notified to the extent that it may wish, with counsel reasonably
     satisfactory to such indemnified party, and after notice from the
     indemnifying party to such indemnified party of its election so to assume
     the defense thereof, the indemnifying party shall not be liable to such
     indemnified party for any legal fees or other expenses subsequently
     incurred by the latter in connection with the defense thereof other than
     reasonable costs of investigation; provided, however, that if, in such
     indemnified party's reasonable judgment, a conflict of interest between
     such indemnified and indemnifying parties may exist in respect of such
     claim, such indemnified party shall be entitled to separate counsel at the
     expense of the indemnifying party; and provided, further, that[, unless
     there exists a conflict of interest among indemnified parties,] all
     indemnified parties in respect of such claim shall be entitled to only one
     counsel or firm of counsel for all such indemnified parties. In the event
     an indemnifying party shall not be entitled, or elects not, to assume the
     defense of a claim, such indemnifying party shall not be obligated to pay
     the fees and expenses of more than one counsel or firm of counsel for all
     parties indemnified by such indemnifying party in respect of such claim,
     unless in the reasonable judgment of any such indemnified party a conflict
     of interest may exist between such indemnified party and any other of such
     indemnified parties in respect of such claim, in which event the
     indemnifying party shall be obligated to pay the fees and expenses of such
     additional counsel for such indemnified party or parties. No indemnifying
     party shall, without the consent of the indemnified party, consent to entry
     of any judgment or enter into any settlement that (i) does not include as
     an unconditional term thereof the giving by the claimant or plaintiff to
     such indemnified party of a release from all Losses in respect of such
     claim or litigation or (ii) would impose injunctive relief on such
     indemnified party. No indemnifying party shall be subject to
 
                                       13
<PAGE>   40
 
     any Losses for any settlement made without its consent, which consent shall
     not be unreasonably withheld.
 
          (d) Other Indemnification.  The provisions of this Section 2.8 shall
     be in addition to any other rights to indemnification or contribution which
     an indemnified party may have pursuant to law, equity, contract or
     otherwise.
 
          (e) Indemnification Payments.  The indemnification required by this
     Section 2.8 shall be made by periodic payments of the amount thereof during
     the course of the investigation or defense, promptly as and when bills are
     received or Losses are incurred.
 
          (f) Contribution.  If for any reason the foregoing indemnity and
     reimbursement is unavailable or is insufficient to hold harmless an
     indemnified party under paragraph (a) or (b) of this Section 2.8, then each
     indemnifying party shall contribute to the amount paid or payable by such
     indemnified party as a result of any Loss (or actions or proceedings,
     whether commenced or threatened, in respect thereof), including, without
     limitation, any legal or other expenses reasonably incurred by them in
     connection with investigating or defending any such Loss, action or
     proceeding, in such proportion as is appropriate to reflect the relative
     fault of the indemnifying party on the one hand and the indemnified party
     on the other. The relative fault shall be determined by reference to, among
     other things, whether the untrue or alleged untrue statement of a material
     fact or the omission or alleged omission to state a material fact relates
     to information supplied by the indemnifying party or the indemnified party
     and the parties' relative intent, knowledge, access to information and
     opportunity to correct or prevent such untrue statement or omission.
     Notwithstanding anything in this Section 2.8(f) to the contrary, no
     indemnifying party (other than the Company) shall be required pursuant to
     this Section 2.8(f) to contribute any amount in excess of the amount by
     which the net proceeds received by such indemnifying party from the sale of
     Registrable Securities in the offering to which the Losses of the
     indemnified parties relate exceeds the amount of any damages which such
     indemnifying party has otherwise been required to pay by reason of such
     untrue statement or omission. No person guilty of fraudulent
     misrepresentation (within the meaning of Section 11(f) of the Securities
     Act) shall be entitled to contribution from any Person who was not guilty
     of such fraudulent misrepresentation.
 
     [2.9 Liquidated Damages.
 
          (a) If the Company shall not have filed, or the SEC shall not have
     declared effective, a Shelf Registration Statement as of the Effective

     principal amount of such Registrable Debt Securities and (ii) in the case
     of Registrable Equity Securities, $.  per share (or in the case of any

<PAGE>   41
 
          (d) If a stop order is imposed or if for any other reason the
     effectiveness of the Shelf Registration Statement is suspended during the
     period specified in the first sentence of Section 2.1(b), the Company shall
     pay liquidated damages to each Holder covered or to be covered by such
     registration statement in an amount equal to (i) in the case of Registrable
     Debt Securities, $.10 per $1,000 outstanding principal amount of such
     Registrable Debt Securities and (ii) in the case of Registrable Equity
     Securities, $.  per share (or in the case of any Warrant, $.  per share
     based on the number of shares issuable upon exercise of the Warrant) for
     each week specified in subsection (g) below.
 
          (e) If the stop order or other suspension of effectiveness of the
     Shelf Registration Statement referred to in clause (d) above shall not have
     been cured within ninety (90) days after such stop order was imposed or the

     the daily liquidated damages set forth in clause (d) above shall increase
     by an amount equal to (i) in the case of Registrable Debt Securities, $.15
     per $1,000 outstanding principal amount of such Registrable Debt Securities
     and (ii) in the case of Registrable Equity Securities, $.  per share (or in
     the case of any Warrant, $.  per share based on the number of shares
     issuable upon exercise of the Warrant) for each week specified in
     subsection (g) below.
 
          (f) If the stop order or other suspension of effectiveness of the
     Shelf Registration Statement referred to in clause (d) above shall not have
     been cured within one hundred and eighty (180) days after such stop order

          (g) The liquidated damages payable to any Holder set forth in this
     Section 2.9 shall begin accruing on the date on which the event triggering
     such liquidated damages occurs and shall cease to accrue (i) with respect
     to clauses (a) through (c) above, on the earlier of the date after the SEC
     declares the Shelf Registration Statement to be effective and the date
     after the SEC declares effective a registration statement effected pursuant
     to Section 2.2 covering such Holder's Registrable Securities and (ii) with
     respect to clauses (d) through (f) above, on the date after reinstatement
     of the effectiveness of the Shelf Registration Statement. The Company will
     pay the liquidated damages due with respect to any Registrable Securities
     at the end of each month during which such damages accrue. Liquidated
     damages shall be paid to the Holders entitled to receive such liquidated
     damages by wire transfer in immediately available funds to the accounts
     designated by such Holders.
 
          (h) The parties hereto agree that (i) the liquidated damages provided
     for in this Section 2.9 constitute a reasonable estimate of the damages
     that will be suffered by each Holder covered or to be covered by the Shelf
     Registration Statement by reason of the failure of the Shelf Registration
     Statement to be filed, to be declared effective and to remain effective in
     accordance with this Agreement and (ii) such liquidated damages shall be
     the sole remedy of each such Holder with respect to the matters set forth
     in this Section 2.9.]
 
     3. Rule 144 and Rule 144A.  (a) The Company will file the reports required
to be filed by it under the Securities Act and the Exchange Act and the rules
and regulations adopted by the SEC thereunder and will take such further action

Registrable Securities without registration under the Securities Act within the
limitation of the exemptions provided by (i) Rule 144, (ii) Rule 144A or (iii)

     any Fidelity Fund, (i) make available adequate current public information
     with respect to the Company within the meaning of paragraph (c)(2) of Rule
     144 and (ii) deliver the information required by Section (d) of Rule 144A
     (such information to be "reasonably current" within the meaning of Section

     4. Term.  This Agreement shall enter into force on the date hereof and
shall continue in full force and effect until the [sixth (6th)] [twelfth (12th)]
anniversary of the date hereof.
 
     5. Amendments and Waivers.  This Agreement may be amended, supplemented or
modified at any time; provided that (i) each of Investor and each Fidelity Fund
(so long as it or any of its Affiliates holds Registrable Securities), (ii) each
Holder of at least      percent (     %) in interest of Registrable Equity
Securities and      percent (     %) in aggregate principal amount of
Registrable Debt Securities then outstanding and (iii) the Company has provided
its written consent to such amendment, supplement or modification. Any term or
condition of this Agreement may be waived at any time by the party that is
entitled to the benefit thereof, but no such waiver shall be effective unless
set forth in a written instrument duly executed by or on behalf of the party
waiving such term or condition. No waiver by any party of any term or condition
of this Agreement, in any one or more instances, shall be deemed to be or
construed as a waiver of the same term or condition of this Agreement on any
future occasion.
 
     6. Entire Agreement.  This Agreement supersedes all prior discussions and
agreements between the parties with respect to the subject matter hereof
(including, without limitation, Section 11 of the Investment Agreement) and
contains the sole and entire agreement between the parties hereto with respect
to the subject matter hereof.
 
     7. No Third-Party Beneficiary.  The terms and provisions of this Agreement
are intended solely for the benefit of each party, their respective Successors
or permitted assigns and it is not the intention of the parties to confer
third-party beneficiary rights upon any other Person other than (i) any
Affiliate of Investor or Fidelity, (ii) any transferee, direct or indirect, of
any of the Registrable Securities held by Investor or Fidelity or (iii) any
other Person entitled to notice of the registration of Registrable Securities
under Sections 2.2(c) or 2.3(a), to indemnity under Section 2.8 [or to
liquidated damages under Section 2.9].
 
     8. Invalid Provisions.  If any provision of this Agreement is held to be
illegal, invalid or unenforceable under any present or future law, (i) such
provision will be fully severable, (ii) this Agreement will be construed and
enforced as if such illegal, invalid or unenforceable provision had never
comprised a part hereof, (iii) the remaining provisions of this Agreement will
remain in full force and effect and will not be affected by the illegal, invalid
or unenforceable provision or by its severance herefrom and (iv) in lieu of such
illegal, invalid or unenforceable provision, there will be added automatically
as a part of this Agreement a legal, valid and enforceable provision as similar
in terms to such illegal, invalid or unenforceable provision as may be possible.
 
     9. Nominees for Beneficial Owners.  In the event that any Registrable
Securities are held by a nominee for the beneficial owner thereof, the
beneficial owner thereof may, at its election, be treated as the holder of such
Registrable Securities for purposes of request or other action by any Holder or
Holders pursuant to this Agreement or any determination of any amount of shares
of Registrable Securities held by any Holder or Holders of Registrable
Securities contemplated by this Agreement. If the beneficial owner of any
Registrable Securities so elects, the Company may require assurances reasonably
satisfactory to it of such owner's beneficial ownership of such Registrable
Securities. For purposes of this Agreement, "beneficial ownership" and
"beneficial owner" refer to beneficial ownership as defined in Rule 13d-3
(without regard to the 60-day provision in paragraph (d)(1)(i) thereof) under
the Exchange Act.

in Section 2.9], the parties agree that, to the extent permitted by law, (i) the
obligations imposed on them in this Agreement are special, unique and of an
extraordinary character, and that in the event of a breach by any such party
damages would not be an adequate remedy; (ii) each of the other parties shall be
entitled to specific performance and injunctive and other equitable relief in
addition to any other remedy to which it may be entitled at law or in equity;
and (iii) any requirement for the securing or posting of any bond in connection
with the obtaining of any such injunctive or other equitable relief is hereby
waived.]
 
     14. GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN

other holder of its securities rights with respect to the registration of such
securities under the Securities Act without the prior written consent of
Investor and each Fidelity Fund (so long as they or their Affiliates hold
Registrable Securities).] The Company represents and warrants that, other than
as provided herein, it has not granted to any other Person rights with respect
to the registration of any Registrable Securities or any other securities issued

     16. Attorneys' Fees.  In any action or proceeding brought to enforce any

                  MANAGEMENT RESIGNATION ALLOWANCE GUIDELINES
                               NOVEMBER 18, 1993
 
PROGRAM PURPOSE
 
     The plan is intended to provide eligible employees with reasonable
transition support in order for them to seek career opportunities outside the
company. Management can use the plan after other reasonable alternatives for
dealing with the situation have been exhausted.
 
ELIGIBILITY
 
     Eligibility for the program is determined by the Company and is intended to
apply to management employees who permanently end their employment relationship
with AWA. Eligible management employees include those whose positions are
eliminated or downgraded in conjunction with a reorganization of
responsibilities or priorities within the Company or whose particular services
no longer fit the needs of the Company. All or some of the functions may be
transferred to another position or eliminated as a result of the reorganization.
 
     All resignation allowances are subject to case-by-case review by the
Compensation Committee of the Board of Directors. All resignation allowances for
directors, senior directors and officers of the corporation and all resignation
allowances for other management personnel in amounts in excess of twenty-six
(26) weeks pay must be approved by the Compensation Committee.
 
     The plan is not intended to relieve management of its responsibility to
appropriately deal with individual performance issues on a firm and constructive
basis. Specifically, the plan is not available for:
 
     - Employees with less than one full year of AWA service.
 
     - Employees subject to termination for cause, for example, an employee with
       an ongoing non-performance problem.
 
     - Employees guilty of serious misconduct, for example, stealing or willful
       or negligent destruction of AWA property.
 
PLAN DESIGN
 
     - The resignation allowance payments are based on Current Annual
       Compensation of three (3) weeks pay for each year of full-time AWA
       service (partial years to be pro-rated to date of termination) with a
       four (4) week minimum and a fifty-two (52) week maximum. If applicable,
       any unearned portion of a salary advance will be reimbursed to the
       company or will be deducted from the resignation allowance.
 
     - Five percent (5%) increase in allowance period for each year over age 40,
       not to exceed 52-weeks combined maximum payment.
 
     - Group medical/life coverages continue during the allowance period at the
       same cost paid by active employees.
 
     - Travel privileges on AWA continue during the allowance period. Travel
       privileges with other carriers vary based on the agreements with those
       carriers. All travel privileges cease if the resigned employee becomes
       employed by another airline.
 
     - The resignation date is the termination date for purposes of 401(k) and
       incentive stock options.
 
     - Outplacement services through an outplacement agency approved by Human
       Resources will be made available on a case-by-case basis with a maximum
       per employee cost to AWA of $5,000.

PROCESS
 
     1. Before discussing the resignation program with a potential candidate,
the supervising Officer or Director will review the situation with the Senior
Director, Human Resources, to confirm plan eligibility. The Senior Director,
Human Resources, will then coordinate approval of the resignation package as
required. Any exceptions to these guidelines require the advance review by Human
Resources and the approval of the CEO and the Compensation Committee of the
Board of Directors.
 
     2. Human Resources will prepare the resignation agreement documents,
including the resignation allowance payment calculation and employee benefits
summary.
 
     3. The supervising Officer or Director will make the offer to the employee
with appropriate coordination from Human Resources.
 
     4. The resigned employee is "out-processed" by Human Resources, Payroll and
the various employee benefits departments.

     KEY EMPLOYEE PROTECTION AGREEMENT ("Agreement"), dated June 27, 1994, by
and between AMERICA WEST AIRLINES, INC., a Delaware corporation (the "Company"),
and WILLIAM A. FRANKE ("Franke").
 
     WHEREAS, Franke is the Chairman of the Board and Chief Executive Officer of
the Company; and
 
     WHEREAS, at the time of Franke's employment as Chairman of the Board in
1992, the Company's Board of Directors and debtor-in-possession lenders agreed,
among other things, to use their best efforts to cause any plan of
reorganization filed with the Bankruptcy Court (as hereinafter defined) relating
to the Company to provide for the payment to Franke, upon substantial
consummation of such plan of reorganization, of a confirmation success bonus of
not less than $500,000; and
 
     WHEREAS, with significant contribution from Franke in his capacities as
Chairman of the Board and Chief Executive Officer of the Company, significant
financial and operating progress has been made by the Company and other actions
have been taken which have enhanced, and in the future are expected to further
enhance, the value of the Company's estate for the benefit of its creditors and
other constituencies; and
 
     WHEREAS, under Franke's leadership, the Company is currently endeavoring to
develop and finalize a confirmable Plan of Reorganization (as hereinafter
defined); and
 
     WHEREAS, the services and knowledge of Franke are valuable to the Company
in many respects, including (without limitation) the rendering of advice to the
Company and its Board of Directors with respect to the difficult and complex
process of developing and finalizing a confirmable Plan of Reorganization; and
 
     WHEREAS, the Company considers it prudent to enter into this Agreement in
order to (i) better secure Franke's continued services, (ii) ensure Franke's

a Change in Control (as hereinafter defined) and (iii) define the nature and
terms of Franke's severance benefits following a Change in Control.
 
     NOW THEREFORE, for and in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties (intending to be legally bound) hereby covenant and

        Board (the "Incumbent Board"), cease for any reason to constitute at
        least a majority of the Board; provided, however, that any individual
        becoming a director subsequent to the date hereof whose election, or
        nomination for election by the Company's stockholders, was approved by a
        vote of at least a majority of the directors then comprising the
        Incumbent Board shall be considered as though such individual were a
        member of the Incumbent Board; or
 
             (ii) any individual, entity or group (within the meaning of Section
        13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended)
        acquires the beneficial ownership (within the meaning of Rule 13d-3

          (d) "Company Affiliate" means any corporation, partnership or other
     business entity directly or indirectly controlling, controlled by or under
     common control with, the Company. As used in this definition, the term

     direct or cause the direction of the management and policies of a
     corporation, partnership or other business entity, whether through
     ownership of voting securities, by contract or otherwise.
 
          (e) "Confirmation Bonus" means any reorganization success bonus
     payable to Franke pursuant to a Plan of Reorganization in the event such
     Plan of Reorganization is confirmed and consummated.
 
          (f) "Confirmation Date" means the date a Plan of Reorganization is
     confirmed by the Bankruptcy Court.
 
          (g) "Plan of Reorganization" means any plan of reorganization which
     (i) is filed with the Bankruptcy Court and (ii) contemplates and, if
     confirmed and consummated, would result in the emergence of the Company
     from its Chapter 11 bankruptcy proceedings.
 
          (h) "Severance Payment" means as specified in Section 2 below.
 
          (i) "Termination Date" means as specified in Section 2 below.
 
     2. Severance Payment.  (a) If a Change in Control occurs in connection with
the consummation of a Plan of Reorganization and if, for any reason (including,
without limitation, a voluntary resignation or an involuntary removal but
excluding death), Franke ceases to serve as the Chairman of the Board and the
Chief Executive Officer of the Company at any time during the period of 180 days
beginning on the Confirmation Date, the Company agrees to pay to Franke,
promptly after the date on which Franke ceases to be the Chairman of the Board
and the Chief Executive Officer of the Company ("Termination Date"), a lump sum
amount (the "Severance Payment") equal to 200% of the sum of (i) Franke's annual
base salary as in effect immediately prior to the Termination Date and (ii)
Franke's annual administrative expense allowance as in effect immediately prior
to the Termination Date; provided, however, that the Severance Payment shall be
reduced by the amount of any Confirmation Bonus actually paid to Franke prior to
the Termination Date.
 
     (b) If all or any portion of the Severance Payment is actually paid to
Franke, any Confirmation Bonus thereafter payable to Franke shall be reduced by
the amount of the Severance Payment actually paid to Franke unless the payment
of such amount to Franke was taken into account in determining the amount of
such Confirmation Bonus.
 
     3. Medical Insurance.  During the 12-month period following the Termination
Date, the Company, at its cost, shall maintain in full force and effect for the
continued benefit of Franke and Franke's dependents all benefits available to
Franke and Franke's dependents under all medical plans and programs of the
Company, provided that (i) Franke's continued participation is possible under
the terms and provisions of such plans and programs and (ii) Franke pays the
regular employee contribution, if any, required by such plans and programs. In
the event that participation by Franke (or his dependents) in any such plan or
program after the Termination Date is barred pursuant to the terms thereof, or
in the event the Company shall terminate any such plan or program, the Company
shall obtain for Franke (and/or his dependents) comparable coverage under
individual policies.
 
     4. Life Insurance.  During the 12-month period following the Termination
Date, the Company, at its cost, shall continue to provide Franke all life
insurance coverages (and in the same amounts) provided to him by the Company
immediately prior to the Termination Date.
 
     5. Travel Privileges.  The Company shall provide Franke (and wife and his
dependents) such lifetime on-line and interline, positive space travel
privileges subject to the terms of the Company's non-revenue travel policy for
retired executives as from time to time in effect.
 
     6. Accrued Vacation Pay, etc.  Promptly after the Termination Date, the

accrued by Franke as of the Termination Date and (ii) all unpaid benefits earned
by Franke as of the Termination Date under any and all incentive compensation
plans or programs of the Company.

<PAGE>   50
 
     7. Tax Withholdings.  The Company shall be entitled to withhold from all
payments hereunder all applicable taxes (federal, state or other) which it is
required to withhold therefrom.
 
     8. Successors; Binding Agreement.  (a) This Agreement shall not be
terminated by the merger or consolidation of the Company whereby the Company is
or is not the surviving or resulting corporation or as a result of any transfer
of all or substantially all the assets of the Company. In the event of any such
merger, consolidation or transfer of assets, the provisions of this Agreement
shall be binding upon the surviving or resulting corporation or the person or
entity to which such assets are transferred.
 
     (b) The Company agrees that concurrently with any merger, consolidation or
transfer referred to in paragraph (a) above, it will cause any successor or
transferee to unconditionally assume in writing all of the obligations of the
Company hereunder on terms and conditions reasonably satisfactory to Franke.
Failure of the Company to obtain such assumption prior to the effectiveness of
any such merger, consolidation or transfer shall be a breach of this Agreement
and shall entitle Franke to immediately receive the Severance Payment from the
Company and, for purposes of implementing the foregoing, the date on which such
merger, consolidation or transfer becomes effective shall be deemed to be the
Termination Date.
 
     (c) This Agreement shall inure to the benefit of and be enforceable by
Franke's personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees. If Franke should die
while any amounts would still be payable to Franke hereunder if Franke had
continued to live, all such amounts, unless otherwise provided herein, shall be
paid in accordance with the terms of this Agreement to such person or persons
appointed in writing by Franke to receive such amounts or, if no person is so
appointed, to Franke's estate.
 
     9. No Mitigation.  The provisions of this Agreement are not intended to,
nor shall they be construed to, require that Franke seek or accept other
employment following a termination of employment. Except as provided in Section
1(a), the Company's obligations to make the payments to Franke required under
this Agreement or any other agreement and otherwise to perform its obligations
hereunder shall not be affected by any set off, counterclaim, recoupment,
defense or other claim, right or action that the Company may have against
Franke.
 
     10. Expense Reimbursement.  If any litigation, contest or dispute shall
arise under this Agreement involving the failure or refusal of the Company to
fully perform in accordance with the terms hereof, the Company shall reimburse
Franke, on a current basis, for all legal fees and expenses, if any, incurred by
Franke, on a current basis, for all legal fees and expenses, if any incurred by
Franke in connection with such litigation, contest or dispute, together with
interest thereon at the rate of 10% per annum, such interest to accrue from the
date the Company receives Franke's statement for such fees and expenses through
the date of payment thereof; provided, however, that in the event the final
resolution of such litigation, contest or dispute includes a finding denying, in
total, Franke's claims in such litigation, contest or dispute, Franke shall be
required to refund to the Company, over a period not to exceed 12 months from
the date of such resolution, all sums advanced to Franke pursuant to this
Section 10.
 
     11. Assignability.  The Company shall have the right to assign this
Agreement and to delegate all rights, duties and obligations hereunder, either
in whole or in part, to any affiliate of the Comapny, provided that no such
assignment or delegation shall relieve the Company of its obligations under this
Agreement.
 
     12. Notices.  All notices and all other communications to the parties shall
be in writing and addressed (i) if to the Company, at its principal office
address or such other address as it may have designated by written notice to
Franks for purposes hereof, directed to the attention of the Board with a copy
to the Secretary of the Company and (ii) if to Franke, at his residence address
on the records of the Company or to such other address as he may have designated
to the Company in writing for purposes hereof. Each such notice or other
communication shall be deemed to have been duly given when delivered or mailed
by United States registered mail, return receipt requested, postage prepaid,
except that any notice of change of address shall be effective only upon
receipt.

     13. Severability.  The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, which shall remain in full force and effect.
 
     14. Amendments and Waivers.  No provision of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in writing and signed by Franke and a duly authorized officer of the
Company. No waiver by either party hereto at any time of any breach by the other
party hereto of, or in compliance with, any condition or provision of this
Agreement to be performed by such other party shall be deemed a waiver of
similar or dissimilar provisions or conditions at the same or at any prior or
subsequent time.
 
     15. Benefits Not Exclusive.  The rights of and benefits payable to Franke
or his beneficiaries under this Agreement are not exclusive and are in addition
to any rights of and benefits payable to Franke or such beneficiaries under any
other agreement between Franke and the Company or under any employee benefit
plan or compensation program of the Company.
 
     16. Counterparts.  This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same instrument.

Board of Directors
America West Airlines, Inc.

Phoenix, Arizona 85034
 
Gentlemen:
 
     We have acted as counsel for America West Airlines, Inc. (the "Company") in
connection with the Company's Registration Statement on Form S-1 (the
"Registration Statement") to be filed with the Securities and Exchange
Commission (the "Commission") under the Securities Act of 1933, as amended (the
"Act"), relating to (i) shares of Class B Common Stock of the Company, par value
$.01 per share (the "Class B Common Stock"), (ii) warrants to purchase Class B
Common Stock (the "Warrants"), and (iii) senior unsecured notes of the Company
(the "Senior Notes") (the Class B Stock, Warrants and Senior Notes are
collectively referred to herein as the "Securities"), to be offered from time to
time pursuant to Rule 415 under the Act by certain selling securityholders of
the Company. The Securities are being issued pursuant to the Company's plan of
reorganization under Chapter 11 of the United States Bankruptcy Code as
described in the Registration Statement (the "Plan of Reorganization"). At your
request, this opinion is being furnished to you for filing as Exhibit 5.1 to the
Registration Statement.
 
     In our capacity as counsel for the Company in connection with the
registration by the Company and proposed issuance of the securities described
herein, we have examined the charter and bylaws of the Company, and have
examined the originals, or copies otherwise identified, of corporate records of
the Company, as furnished to us by the Company, certificates, advices and
assurances of public officials and of representatives of the Company, statutes
and other instruments and documents, as a basis for the opinions hereinafter
expressed. In giving such opinions, we have relied upon certificates of officers
of the Company with respect to the accuracy of the material factual matters
contained in such certificates.
 
     We have assumed that all signatures on all documents examined by us are
genuine, that all documents submitted to us as originals are authentic, that all
documents submitted to us as copies are true and correct copies of the originals
thereof and that all information submitted to us was accurate and complete.
 
     Based upon our examination as aforesaid, and subject to the assumptions and
limitations herein set forth, we are of the opinion that:
 
          1. The shares of Class B Common Stock to be issued pursuant to the
     Plan of Reorganization have been duly authorized by all necessary corporate
     action on the part of the Company and such shares, upon issuance pursuant
     to and in accordance with the Plan of Reorganization, will constitute
     validly issued, fully paid and non-assessable shares of common stock of the
     Company.

          2. The Warrants to purchase Class B Common Stock have been duly
     authorized by all necessary corporate action on the part of the Company
     and, upon the issuance of the Warrants pursuant to and in accordance with
     the Plan of Reorganization and the Warrant Agreement, the Warrants will
     constitute valid and binding obligations of the Company enforceable in
     accordance with their terms, except as limited by applicable bankruptcy,
     insolvency, reorganization, moratorium and similar laws and by principles
     of equity.
    
 
   
          3. The Senior Notes have been duly authorized by all necessary
     corporate action on the part of the Company and, upon the issuance of the
     Senior Notes pursuant to and in accordance with the Plan of Reorganization
     and the Indenture, the Senior Notes will constitute valid and binding
     obligations of the Company enforceable in accordance with their terms,
     except as limited by applicable bankruptcy, insolvency, reorganization,
     moratorium and similar laws and by principles of equity.
    
 
   
     In rendering the opinions set forth above, we express no opinion as to the
adequacy or sufficiency of the consideration paid or to be paid or contributions
made or to be made for any of the Securities in connection with the Plan of
Reorganization.
    
 
   
     This opinion is limited in all respects to the corporate law of the State
of Delaware, the laws of the State of New York and of the United States of
America. To the extent any of such opinions relate to the corporate law of the
State of Delaware, we have formed our opinion based solely upon a reading of the
Delaware General Corporation Law. We express no opinion with respect to the laws
or regulations of other jurisdictions applicable by virtue of conflict of laws
or other principles.
    
 
   
     We hereby consent to the filing of this opinion with the Commission as an
exhibit to the Registration Statement and to the use of our name in the
Registration Statement under the caption "Legal Matters."

                             CODE SHARING AGREEMENT
 
     This Agreement is made this 29th day of June, 1994, by and between
CONTINENTAL AIRLINES, INC. ("CAL"), a Delaware corporation, and AMERICA WEST
AIRLINES, INC. ("AWA"), Debtor and Debtor-in-Possession, a Delaware corporation.
 
                                    RECITALS
 
     CAL and AWA are each certificated air carriers providing air transportation
services in their respective areas of operation.
 
     CAL and AWA desire to cooperate in the coordination of schedules by
allowing AWA to market its flight operations under the CO* designator and CAL to
market its flight operations under the HP* designator.
 
     NOW, THEREFORE, in consideration of the premises and the mutual promises
herein contained, CAL and AWA hereby agree as follows:
 
     1. Schedules to be Operated.  It is the intent of the parties to share
their two letter designator codes, "CO*" in the case of CAL and "HP*" in the
case of AWA. CAL operated Shared Code Segments (as herein defined) will be
marketed under not only CAL's "CO" designator code but also under AWA's "HP*"
designator code, and AWA operated Shared Code Segments will be marketed under
not only AWA's "HP" designator code, but also under CAL's "CO*" designator code.
Schedule 1 hereto sets forth the flight segments where shared code segments
("Shared Code Segments") will operate at the commencement of this Agreement and
some of the Shared Code Segments that will be operated in the future; however,
it is the intent of the carriers to designate, to the maximum extent permitted
by law, all flights operated by either as Share Code Segments during the term of
this Agreement. The carriers shall meet together every six months that this
Agreement is in effect to discuss the appropriateness of expanding or
contracting the list of city pairs on Schedule 1.
 
     2. Code Sharing Licenses.
 
          (a) CO* License.
 
             (i) Grant of License.  Subject to the terms and conditions of this
        Agreement, CAL hereby grants to AWA a nonexclusive, nontransferable,
        revocable license to use the CO* designator code on all of its flights
        operated as a Shared Code Segments. (AWA flights flown using the CO*
        code are hereinafter referred to as "CO* Flights").
 
             (ii) Control of CO* Flights.  AWA shall have sole responsibility
        for and control over, and CAL shall have no responsibility for, control
        over or obligations or duties with respect to, each and every aspect of
        AWA's operations including, without limitation, scheduling (except as
        provided in Section 12 hereto), pricing (except as provided in Section
        13 hereto), planning of flight itineraries and routings, reservations,
        reservations control/yield management, dispatch, fueling, weight and
        balance, flight release, maintenance, and flight operations and
        compliance with applicable rules and regulations.
 
          (b) HP* License.
 
             (i) Grant of License.  Subject to the terms and conditions of this
        Agreement, AWA hereby grants to CAL a nonexclusive, nontransferable,
        revocable license to use the HP* designator code on all of its flights
        operated as a Shared Code Segment. (CAL flights flown using the HP* code
        are hereinafter referred to as "HP* Flights").
 
             (ii) Control of HP* Flights.  CAL shall have sole responsibility
        for and control over, and AWA shall have no responsibility for, control
        over or obligations or duties with respect to, each and every aspect of
        CAL's operations including, without limitation, scheduling (except as
        provided in
 
                                        1

          Section 12 hereto), pricing (except as provided in Section 13 hereto),
          planning of flight itineraries and routings, reservations,
          reservations control/yield management, dispatch, fueling, weight and
          balance, flight release, maintenance, and flight operations and
          compliance with applicable rules and regulations.
 
     3. Confidential Information.  Neither AWA nor CAL shall disclose to the
other carrier or be required to disclose by the other carrier any information
relating to its scheduling (except as provided in Section 12 hereto), pricing,
inventory control or flight profitability. Neither AWA nor CAL shall disclose
the terms of this Agreement or any proprietary information with respect to the
other obtained as a result of this Agreement, either during the term hereof or
thereafter except as may be required by law or by any order of a court or
administrative agency, and then on ten days' notice to the other. The parties
hereto recognize that, in the course of the performance of each of the
provisions hereof, each carrier may be given and may have access to confidential
and proprietary information of the other carrier, including proposed schedule
and fare changes, statistical data regarding loads and fares, sales and
promotional programs and other operating and competitive information
("Confidential Information"). Each carrier shall preserve, and shall ensure that
each of its officers, agents, consultants and employees who receive Confidential
Information preserve, the confidentiality of the other carrier's Confidential
Information.
 
     4. Quality of Service.  Each carrier shall perform its service with respect
to its flights operated under the designation of the other carrier in a timely,
expert and quality manner. Each carrier agrees that, in conducting flight
operations under the designator of the other carrier, it will employ prudent
safety and loss prevention policies.
 
     5. Audit.
 
          (a) CAL Audit.  CAL shall have the right, at its own cost, to inspect,
     review, and observe AWA's operations of CO* Flights, and/or to conduct a
     full safety and/or service audit of AWA's operations, manuals and
     procedures reasonably related to CO* Flights, at such intervals as CAL
     shall reasonably request. In the exercise of such right, CAL does not
     undertake any responsibility for the performance of AWA's operations. CAL
     shall coordinate its safety and service audits with AWA so as to avoid
     disruptions of AWA's operations. Any safety audit may include, without
     limitation, maintenance and operation procedures, crew planning,
     reservations, passenger and baggage handling, customer service, personnel
     records, spare parts, inventory records, training records and manuals,
     flight, flight training and operational personnel records. This paragraph
     shall not entitle CAL access to AWA's records, documents or systems
     relating to its pricing, inventory control or flight profitability.
 
          (b) AWA Audit.  AWA shall have the right, at its own cost, to inspect,
     review, and observe CAL's operations of HP* Flights, and/or to conduct a
     full safety and/or service audit of CAL's operations, manuals and
     procedures reasonably related to HP* Flights, at such intervals as AWA
     shall reasonably request. In the exercise of such right, AWA does not
     undertake any responsibility for the performance of CAL's operations. AWA
     shall coordinate its safety and service audits with CAL so as to avoid
     disruptions of CAL's operations. Any safety audit may include, without
     limitation, maintenance and operation procedures, crew planning,
     reservations, passenger and baggage handling, customer service, personnel
     records, spare parts, inventory records, training records and manuals,
     flight, flight training and operational personnel records. This paragraph
     shall not entitle AWA access to CAL's records, documents or systems
     relating to its pricing, inventory control or flight profitability.
 
     6. Public Relations.  In the event of any irregularity in Shared Code
Segments' operations, including, without limitation, any event causing damage to
persons or property, the operating carrier shall identify itself as being
operated independently of the carrier whose code is being used, and as being
solely responsible for its operations. Either carrier may state that it holds a
code sharing license from the other carrier and that it obtains certain services
from the other carrier if third parties inquire as to such relationship.
 
     7. Irregularities in Operations.  AWA shall promptly notify CAL of all
irregularities involving a CO* Flight which result in any damage to persons or
property as soon as such information is available and shall furnish to CAL as
much detail as practicable. CAL shall promptly notify AWA of all irregularities
involving a
 
                                        2

HP* Flight which result in any damage to persons or property as soon as such
information is available and shall furnish to AWA as much detail as practicable.
 
     8. Reporting Obligation.
 
          (a) Changes in Service.  Each carrier shall give the other carrier 60
     days advance notice (or notice as far in advance as possible if 60 days is
     impracticable) of any intended (i) changes to its operating specifications,
     or (ii) material changes to the manner of conducting its business or the
     nature of its product. In the event any such change materially affects the
     value or risk to the other carrier of this Code Sharing Agreement in the
     other carrier's reasonable judgment, the other carrier shall be entitled to
     terminate this agreement if the change is implemented.
 
          (b) Correspondence from Government Authorities.  AWA shall immediately
     provide CAL copies of any correspondence received from government authority
     which, with respect to CO* Flights, references (i) any alleged
     noncompliance with rules or regulations affecting air transportation, or
     (ii) any investigation of AWA performed or proposed by any government
     authority, including, without limitation, any communication issued by a
     government authority concerning the airworthiness of AWA's aircraft, the
     compliance of AWA's personnel with required operational or training
     procedures or any other matter relating to the safe operation of AWA
     aircraft.
 
          CAL shall immediately provide AWA copies of any correspondence
     received from any government authority which, with respect to HP* Flights,
     references (i) any alleged noncompliance with rules or regulations
     affecting air transportation, or (ii) any investigation of CAL performed or
     proposed by any government authority, including, without limitation, any
     communication issued by a government authority concerning the airworthiness
     of CAL's aircraft, the compliance of CAL's personnel with required
     operational or training procedures or any other matter relating to the safe
     operation of CAL aircraft.
 
          (c) Notice of Complaints.  AWA shall monthly furnish CAL a summary of
     complaints, notices or violation, request to cease activity or similar
     correspondence which reasonably relate to CO* Flights and which are
     received by AWA from passengers, any government authority, or other
     parties. CAL shall monthly furnish AWA a summary of complaints, notices or
     violation, request to cease activity or similar correspondence which
     reasonably relate to HP* Flights and which are received by CAL from
     passengers, any government authority, or other parties. Each carrier shall
     comply with the other carrier's reasonable requests for actual copies of
     any such documents.
 
     9. Flight Display.
 
          (a) All Shared Code Segments will be included in the availability and
     fare displays of all computerized reservations systems in which CAL and AWA
     participate, the Official Airline Guide (to the extent agreed upon) and
     CAL's and AWA's internal reservation systems, under the shared code as well
     as the operator's own code, to the extent possible. CAL and AWA will take
     the appropriate measures necessary to ensure the display of Shared Code
     Segments in accordance with the preceding sentence.
 
          (b) CAL and AWA will disclose and identify the Shared Code Segments to
     the public as actually being a flight of and operated by the operating
     carrier, in at least the following ways:
 
             (i) a symbol will be used in timetables and computer reservation
        system indicating that Shared Code Segments are actually operated by the
        other carrier;
 
             (ii) to the extent reasonable, messages on airport flight
        information displays will identify the operator of flights shown as
        Shared Code Segments;
 
             (iii) CAL and AWA advertising concerning Shared Code Segments and
        CAL and AWA reservationists will disclose the operator of each flight;
        and
 
             (iv) in any other manner prescribed by law.
 
                                        3
<PAGE>   57
 
     10. Terms and Conditions of Carriage and Claims Procedures.
 
          (a) In all cases the contract of carriage between a passenger and a
     carrier will be that of the carrier whose designator code is used and not
     that of the carrier operating the Shared Code Flight.
 
          (b) The carriers will use existing IATA procedures when handling and
     settling claims made by customers in connection with Shared Code Segments.
 
     11. Irregularity Handling.
 
          (a) In the event of flight delays, cancellations or other schedule
     irregularities that affect Shared Code Segments, the operating carrier will
     inform the carrier whose designator is also used of all pertinent
     information concerning an irregularity for customer information purposes.
 
          (b) The parties agree that they will cooperate in all available ways
     to accommodate passengers experiencing flight irregularities and that
     neither will forbear from providing such assistance because the other may
     have been responsible for the flight irregularity. In the event of a flight
     irregularity, the carrier causing or experiencing the irregularity shall
     bear all related costs associated with accommodating the passengers who
     have been delayed. The carriers will review existing procedures for
     accommodating interline passengers with respect to flight irregularities
     and oversales to determine their adequacy for the purposes of this
     Agreement and will make such adjustments in existing procedures as they
     find necessary or appropriate.
 
     12. Airport Operational Assistance.  CAL and AWA will cooperate to
coordinate and maintain their schedules to minimize the waiting time and to
maximize convenience of passengers who are connecting from a CAL to AWA flight
segment (or vice versa). Each carrier will provide the other with the airport
operational assistance that is required to assure schedule compatibility for
Shared Code Segments for which a Through Fare (as such term is hereinafter
defined) may be applicable. The carriers will use their respective best efforts
to align gates and ticket counter space where Shared Code Segments operate.
 
     13. Pricing and Capacity Control of Shared Code Segments.
 
                         [CONFIDENTIAL PORTION DELETED]
 
     15. Compliance with Laws and Regulations.  CAL and AWA each represent,
warrant, and agree that performance of its respective obligations under this
Agreement shall be conducted and all of its personnel shall at all times meet,
be in full compliance with and have all required licenses under any and all
applicable statutes, orders, rules and regulations, and satisfy all applicable
insurance requirements, whether in effect or hereafter promulgated of the United
States National Transportation Safety Board, Department of Transportation of
Federal Aviation Administration, Department of Defense of any country or
territory with jurisdiction over the Shared Code Segments.
 
     16. Independent Parties.
 
          (a) Independent Contractors.  It is expressly recognized and agreed
     that each carrier, in its performance and otherwise under this Agreement,
     is and shall be engaged and acting as an independent contractor and in its
     own independent and separate business; that each carrier shall retain
     complete and exclusive control over its staff and operations and the
     conduct of its business; and that each carrier shall bear and pay all
     expenses, costs, risks and responsibilities incurred by it in connection
     with its obligations under this Agreement. Neither CAL nor AWA nor any
     officer, employee, representative, or agent of CAL or AWA shall in any
     manner, directly or indirectly, expressly or by implication, be deemed to
     be, or make any representation or take any action which may give rise to
     the existence of, any employment, agent, partnership, or other like
     relationship as between CAL and AWA but each carrier's relationship as
     respects the other carrier in connection with this Agreement is and shall
     remain that of an independent contractor.
 
          (b) Status of Employees.  The employees, agents and/or independent
     contractors of AWA shall be employees, agents, and independent contractors
     of AWA for all purposes, and under no circumstances
 
                                        4
<PAGE>   58
 
     shall be deemed to be employees, agents or independent contractors of CAL.
     The employees, agents and independent contractors of CAL for all purposes,
     and under no circumstances shall be deemed to be employees, agents or
     independent contractors of AWA. In its performance under this Agreement,
     each carrier shall act as an independent contractor and not as an agent for
     the other. CAL shall have no supervisory power or control over any
     employees, agents or independent contractors employed by AWA, and AWA shall
     have no supervisory power or control over any employees, agents and
     independent contractors employed by CAL.
 
          (c) Liability For Employee Costs.  Each carrier, with respect to its
     own employees (hired directly or through a third party), accepts full and
     exclusive liability for the payment of worker's compensation and/or
     employer's liability (including insurance premiums where required by law)
     and for the payment of all taxes, contributions or other payments for
     unemployment compensation, vacations, or old age benefits, pensions and all
     other benefits now or hereafter imposed upon employers with respect to its
     employees by any government or agency thereof or any other party (whether
     measured by the wages, salaries, compensation or other remuneration paid to
     such employees or otherwise) and each carrier further agrees to make such
     payments and to make and file all reports and returns, and to do everything
     necessary to comply with the laws imposing such taxes, contributions or
     other payments.
 
     17. Indemnification and Insurance.
 
        (a) Indemnification.
 
             (i) AWA hereby assumes liability for, and shall indemnify, defend,
        protect, save and hold harmless CAL, its officers, agents, and employees

        of) any alleged acts or omissions of AWA or its officers, employees, or
        agents which are in any way related to the services contemplated by this
        Agreement. CAL shall give AWA prompt notice of any claim made or suit
        instituted against CAL which, if successful, would result in
        indemnification of CAL hereunder, and CAL shall have the right to
        compromise or participate in the defense of same to the extent of its
        own interest.
 
             (ii) CAL hereby assumes liability for, and shall indemnify, defend,

        of) any alleged acts or omissions of CAL or its officers, employees, or
        agents which are in any way related to the services contemplated by this
        Agreement. AWA shall give CAL prompt notice of any claim made or suit
        instituted against AWA which, if successful, would result in
        indemnification hereunder, and AWA shall have the right to compromise or
        participate in the defense of same to the extent of its own interest.
 
          (b) Insurance Coverage.

               provided thereunder with respect to the other party; and
 
                    (B) to provide that the one party's underwriters shall waive

               directors, officers, agents, employees and other authorized
               representatives, except for gross negligence or wilful
               misconduct, with regard to any breach of warranty on the part of
               the other party or to provide other evidence of such waiver or
               recourse against the other party, its directors, officers,
               agents, employees and other authorized representatives.
 
                    (C) to provide that each party, its directors, officers,

        referred to in Section 17(b)(i) to be duly and properly endorsed to
        provide that said policy or policies or any part or parts thereof shall
        not be canceled, terminated or materially altered, changed or amended by
        each party's insurance underwriters, until after 30 days' prior notice
        to the other party, such notice period to commence when such other party
        actually receives such notice.
 
             (iv) Simultaneously with the commencement of this Agreement, and
        from time to time thereafter upon request by either party, the other
        party shall furnish to the requesting party evidence reasonably
        satisfactory to the requesting party of the aforesaid insurance coverage

        to procure and maintain such insurance or any part thereof. The cost of
        such insurance shall be payable by the first party to the other party
        upon demand by the other party. The procurement of such insurance or any
        part thereof by the other party shall not discharge or excuse the first
        party's obligation to comply with the provisions of Sections 17(b)(i)
        and 17(b)(ii)

     18. Term and Termination.
 
          (a) Term.  Unless the carriers agree to an earlier commencement date,
     the term of this Agreement shall commence as soon as practicable after the
     date that is the later of the date that this Agreement is signed by both
     parties or the date that the investment agreement between AWA and AmWest
     partners, L.P. (the "Investment Agreement") is consummated and shall
     continue until the date immediately preceding the tenth anniversary of the
     commencement date, unless earlier terminated as provided herein, and shall
     continue thereafter until either carrier gives the other carrier notice of
     termination at least 90 days prior to the effective date of such
     termination. In no event shall termination or expiration pursuant to this
     Section 18(a) be effective unless such 90 days' notice is provided.
 
          (b) Termination as a Result of Changes of Law.  In the event there is
     any change in treaties, statutes or regulations of air transportation that
     materially affects the rights and/or obligations presently in force with
     respect to the air transportation services of CAL or AWA or both, relating
     to CO* or HP* Flights, then the carriers will consult, within 30 days after
     any of the occurrences described herein, in order to determine or seek

     or appropriate, including but not limited to the early termination and

        the marketing or operation of a CO* or HP* Flight;
 
             (iv) By either carrier immediately on notice, in the event that the

        terminated prior to its having been consummated;
 
             (v) Except for AWA's currently pending Chapter 11 proceeding, by
        either carrier if a petition is filed by or against the other carrier
        under bankruptcy law, or any other law providing for the relief of
        debtors, and the affected party does not succeed in having such petition
        lifted or stayed within sixty days from the date of entry; the carrier
        at its option may cancel this Agreement immediately and exercise such
        other remedies as may be available at law and/or in equity;
 
             (vi) By either carrier on six months' prior written notice, if a
        carrier, foreign or domestic, that competes with the terminating carrier
        on a material basis, acquires majority ownership of or substantial
        control over the other carrier.
 
             (vii) By CAL immediately on notice if
 
                1. AWA shall fail to maintain any of its aircraft in an
           airworthy condition and conduct its flight operations in accordance
           with the standards, rules and regulations promulgated by any
           government authority; or
 
                2. AWA shall have a completion factor of less then 80% during
           any 20 day period with respect to CO* Flights (including in such

           date of its scheduled operation and excluding flights not completed
           due to weather or labor stoppages); and
 
                                        7

           due to weather or labor stoppages).
 
     19. Booking Fee.  The carrier operating over any segment of a Shared Code
Flight will be responsible for any booking fee relating to such segment charges
by the vendor of a computer reservation system used to create a booking on that
flight. If the booking fee relating to such segment is billed to the carrier
whose designator code is also used for that flight, the operating carrier will
reimburse the carrier whose designator code is also used for that flight.
 
     20. Entire Agreement, Waivers and Amendments.  This Agreement constitutes
the entire understanding of the carriers with respect to the subject matter
hereof superseding all prior discussions and agreements, written or oral. This
Agreement may not be amended, nor may any of its provisions be waived, except by
writing signed by both carriers. No delay on the part of either carrier in
exercising any right power or privilege hereunder shall operate as a waiver

                               SERVICE AGREEMENT
 
     AGREEMENT made this 4th day of September, 1992 by and between America West
Airlines, Inc. ("AWA"), Debtor-In-Possession, a Delaware corporation having a

WITNESSETH:
 
     WHEREAS, AWA holds a certificate of public convenience and necessity issued
by the Department of Transportation ("DOT") authorizing AWA to engage in the
interstate and overseas air transportation of persons, property and mail between
all points in the United States, its territories and possessions;
 
     WHEREAS, Contractor holds a certificate of public convenience and necessity
issued by the Department of Transportation ("DOT") authorizing it to engage in
the interstate air transportation of persons, property and mail between all
points in the United States, its territories and possessions;
 
     WHEREAS, AWA owns various trademarks, service marks and logos, including
"America West Airlines" and distinctive exterior color decor and patterns on its
aircraft, hereinafter referred to individually and collectively as the "AWA
Trademarks;"
 
     WHEREAS, Contractor wishes to acquire a non-exclusive license to use one or
more of AWA's Trademarks in connection with the scheduled air transportation
services operated by Contractor pursuant to this Agreement, including the use of
the "HP" designator code used to identify, in computer systems and elsewhere,
Contractor's scheduled flights operated pursuant to this Agreement;
 
     WHEREAS, Contractor desires to operate, and AWA is willing to contract for,
AMERICA WEST EXPRESS operations in the manner and to the extent hereinafter
described;
 
     NOW, THEREFORE, for and in the consideration of the foregoing premises and
the mutual covenants and obligations hereinafter set forth, the parties to this
Agreement hereby agree as follows:
 
ARTICLE 1 -- COMPLIANCE WITH REGULATIONS
 
     Contractor hereby represents, warrants, and agrees that all air

     (b) All published schedules to be operated by Contractor pursuant to
Section 2.01(a) above or to add new markets other than those listed in Section
2.01(a) above must be submitted to AWA at least 30 days prior to the effective
date of such schedule. Contractor agrees that in the development of its
schedules, it shall consult with AWA and use its best reasonable efforts to
ensure that the primary needs of both local and connecting traffic in AWA
markets are being met. AWA shall not have the right to approve or disapprove
such schedules. AWA retains the right to withhold the use of its code, logo or
trademarks from any flight operated by the Contractor. AWA shall timely file
Contractor's code-shared schedules with its own schedules in accordance with
industry standards provided Contractor's schedules are timely received by AWA.
 
     (c) Notwithstanding anything to the contrary contained in this Section
2.01, Contractor shall be entitled to operate additional services under its own
name in the markets covered by this Agreement; provided that any aircraft used
in providing such services shall not bear AWA's logo or markings.
 
     (d) Contractor shall be the sole and exclusive air carrier authorized by
AWA to operate as AMERICA WEST EXPRESS (or operate by similar AWA turbo-prop
feeder-operation-designation) for all AMERICA WEST EXPRESS flights serving the
Phoenix hub. In consideration of their exclusive air carrier status, Contractor
shall have a right of first refusal to institute any new services (cities or
flights) which are forecast by AWA to be profitable. Such services shall be
inaugurated within 90 days of recommendation by AWA. If Contractor refuses to
provide the requested service, AWA shall have the right to contract with another
carrier to operate that route as an AMERICA WEST EXPRESS, provided that the
service shall be the same as that proposed to Contractor. Contractor shall have
the right of first refusal to provide service to any additional major cities or
hubs wherein AWA may desire to establish a code-sharing agreement. Contractor
shall have 30 days from the time it is offered the additional agreement to
accept or decline such opportunity. If accepted, Contractor shall have 120 days
to prepare itself to fulfill its obligations at the additional city or hub.
 
     (e) Contractor may withdraw from, reduce service, or suspend service in any
of its AMERICA WEST EXPRESS markets listed in Section 2.01(a) after
 
                         [CONFIDENTIAL PORTION DELETED]
 
     Contractor shall then give 30 days' notice to AWA of its desire to affect
service to that market.
 
                                        2
<PAGE>   68
 
     (f) Inauguration of services listed in Section 2.01(a) will be accomplished
according to the transition schedule contained in Exhibit A, made a part of this
agreement and attached hereto.
 
     Section 2.02 Aircraft To Be Used
 
     (a) Contractor will provide the scheduled air services described in Section
2.01 with short-to-medium range, multi-engine, turbine-propeller aircraft. Such
aircraft shall have a minimum of 19 seats and appropriate capacity for passenger
baggage, freight and mail.
 
     (b) Upon filing a Plan of Reorganization with the Bankruptcy Court,
Contractor shall begin to repaint its aircraft used in connection with the
services provided under this Agreement with exterior color decor and Trademarks
to be designed by AWA in consultation with Contractor. The Contractor shall
provide the paint and other materials for the exterior aircraft decor and AWA
shall paint the aircraft in its painting facility. Any change to the exterior
color decor and pattern of the aircraft subsequent to the original design shall
be made at the expense of AWA. AWA understands that the flowage of Contractor's
aircraft prevents Contractor from painting all of its aircraft in AWA colors.
Contractor will attempt to maximize the utilization of AWA painted aircraft on
code-shared routes. AWA understands that on occasion an AWA-colored aircraft may
be used in Contractor's "Mesa" system due to aircraft flowage requirements.
 
     In addition to the use of the AWA Trademarks on its aircraft, Contractor
shall use and display a suitable sign on the exterior of its aircraft
identifying Contractor as the operator of the services being provided pursuant
to this Agreement. The use and display of such sign shall be in compliance with
any applicable FAA rule or directive, shall be visible to passengers approaching
the aircraft for boarding and shall be subject to the prior written approval of
AWA as to its nature, size and location on Contractor's aircraft.
 
     Section 2.03 Flight Crews To Be Used
 
     All services performed by Contractor pursuant to this Agreement shall be
operated with crews consisting of a captain or pilot, and a first officer or
co-pilot. All such crew members shall at all times meet all currently applicable
governmental requirements, as such requirements may be amended from time to time
during the life of this Agreement, and shall be fully licensed and qualified for
the services to be performed hereunder.
 
ARTICLE 3 -- SUPPORT SERVICES AND FACILITIES
 
     Section 3.01 General Provision
 
     AWA and Contractor shall provide support services and facilities to the
extent and in the manner set forth in the subsequent sections of this Article 3.
Such support services and facilities, when furnished by AWA, shall be furnished
only with respect to Contractor's scheduled air services described in Article 2.
 
     Section 3.02 Communications and Reservations
 
     Reservation telephone lines will be maintained by AWA at the points listed
in Article 2 connecting those cities with AWA's reservations center.
Reservations for passengers using the services described in Article 2 and
connecting reservations to AWA or to other air carriers will be made by AWA on a
non-discriminatory basis in accordance with AWA's established methods and
procedures. For passengers originating their travel at points other than those
served by Contractor pursuant to Article 2, either on AWA's system or on the
systems of other airlines, connecting reservations to the services of Contractor
will also be made on a non-discriminatory basis in accordance with currently
established industry methods and procedures. In all cases, AWA will confirm the
reservations of Contractor's passengers through the entire itinerary of their
scheduled trips. When a contact number is supplied by the passengers making such
reservations, AWA will assume the responsibility of notifying passengers of any
changes in Contractor's schedules or operations, provided that Contractor
furnishes AWA with sufficient advance notice of such changes. Contractor will
provide AWA with parameters of Contractor's flight capacity and discount seat
inventory levels and AWA will use its best efforts to accommodate Contractor's
directions as to these levels.

     Section 3.03 Operations
 
     (a) In the event of flight delays, cancellations or other schedule
irregularities affecting Contractor's scheduled services, and as soon as
information concerning such irregularities is available, Contractor shall notify
AWA's flight control center and furnish AWA such information in as much detail
as possible.
 
     (b) Contractor shall be solely responsible for, and AWA shall have no
obligations or duties with respect to the dispatch of Contractor's flights
operated pursuant to this Agreement or otherwise. For the purposes of this
Section 3.03(b), the term "flight dispatch" shall include, but shall not be
limited to, all planning of flight itineraries and routings, fueling and flight
release.
 
     (c) From time to time, and solely upon request of Contractor or its flight
crews, AWA shall provide to Contractor at its cost, such U.S. Weather Bureau
information or data as may be available to AWA; provided that, in furnishing any
such weather information or data to Contractor, neither AWA nor its employees or
agents will be responsible or liable for the accuracy thereof.

     from time to time due to schedule irregularities in Contractor's
     operations.
 
     (b) Contractor shall provide its own services and facilities at all
airports other than Phoenix, Arizona and will provide the following services at

          (1) all passenger screening for passengers arriving on Contractor's

     (d) With respect to airbills issued by Contractor for transportation of
property on Contractor, AWA and other air carriers, and with respect to inbound
collect shipments, handled by Contractor, Contractor shall retain possession of
all cash proceeds collected and received by Contractor throughout the month in
connection with such transactions and all such cash proceeds shall be remitted
to AWA through the Clearing House in accordance with the procedures set forth in
the currently effective Manual of Procedures issued by said Clearing House, but
in no event later than the 28th day of the month following the month in which
such monies or proceeds were collected. Inbound C.O.D. shipments shall be
handled in accordance with established AWA policy. In addition, Contractor shall
prepare and furnish to AWA all written reports, accounts and documents that AWA

different passenger and air freight sales and accounting procedures as may be

airbills or other documents or of a bank in which the party may have deposited

percentage of revenue it derives under this Agreement, and advise Contractor of
the percentage and amount. Contractor will then develop and propose an
advertising program to be funded by the contribution which will then be
submitted to AWA for approval.

House referred to in Article 3 in accordance with the procedures set forth in
the currently effective Manual of Procedures issued by said Clearing House, but
in no event later than the 28th day of month following the month in which

                                        9
<PAGE>   75
 
10 percent, from the due date thereof to the date of payment. It is hereby
mutually agreed and understood by the parties hereto that the aforesaid Service
Charges
 
                         [CONFIDENTIAL PORTION DELETED]
 
AWA will use only the personnel in its employ and the equipment and facilities
which it owns or leases. In the event AWA is required to employ, retain or
otherwise furnish additional personnel or obtain, by purchase, lease or
otherwise any additional facilities or equipment, or incur in any manner
whatsoever any expenses or disbursements in connection with its performance of
this Agreement in excess of the personnel, facilities or equipment being
provided in the normal course of business, Contractor shall reimburse AWA in
full, through the Clearing House for the actual costs of such additional
personnel, facilities and/or equipment, and for any actual expenses or
disbursements incurred by AWA in connection with its performance under this
Agreement; provided that, prior to incurring any such additional costs or
expenses or making any such disbursements, AWA shall first obtain a written
approval therefor from Contractor.
 
     (b) All payments and/or reimbursements contemplated in this Article shall
be deemed to be in addition to and not in lieu of any other payments and/or
reimbursements required of either party hereto by other articles of this
Agreement.
 
     Section 8.02 Records and Reports
 
     (a) Upon either party's request, and until such time as the party advises
the other that such reports are no longer necessary, each party shall furnish to
the requesting party, within 60 days following the close of the first three
fiscal quarters of the party, unaudited financial statements including the
party's current corporate balance sheets and profit and loss statements, and
within 120 days after the close of its fiscal year, each party shall furnish the
other with audited financial statements of such party (or its parent company)
including, either separately or on a consolidated basis, the balance sheet and
profit and loss statements of that party. The appropriate reports filed on Form
10-Q or 10-K shall be satisfactory to fulfill such obligation.
 
     (b) Each party shall also promptly furnish the other with a copy of every
report that it prepares and is required to submit to the FAA, National
Transportation Safety Board ("NTSB") or any other governmental agency, relating
to any accident or incident involving an aircraft used by it in performing
services under this Agreement, when such accident or incident is claimed to have
resulted in the death of or substantial injury to any person or the loss of,
damage to, or destruction of any property.
 
     (c) Each party shall promptly notify the other in writing of (i) any change
in or relinquishment of control of it, (ii) any agreement contemplating such a
change or relinquishment with a copy of such agreement, if in writing, to the
other party, or (iii) any change or contemplated change in the Chief Executive
Officer position of it.
 
ARTICLE 9 -- EFFECTIVE DATE, TERMINATION AND CANCELLATION
 
     Section 9.01 Effective Date and Term
 
     (a) This Agreement will become effective on October 1, 1992 and will
continue in effect thereafter for a period of ten years, unless it is terminated
at an earlier date pursuant to one or more of the provisions of this Article 9.
The AMERICA WEST EXPRESS service described in Section 2 shall commence on the
dates specified in Section 2 and the applicable reservations and ticketing
services shall be made available 30 days in advance of the start of such
services.
 
     (b) In the event there is any change in the statutes governing the economic
regulation of air transportation, or in the applicable rules, regulations or
order of the DOT or some successor agency or department of the government having
jurisdiction over air transportation which change or changes materially affect
the rights and/or obligations presently in force with respect to the air
transportation services of AWA or Contractor, or both, then the parties hereto
will consult, within 30 days after any of the occurrences described
 
                                       10
<PAGE>   76
 
herein, in order to determine what, if any, changes to this Agreement are
necessary or appropriate, including but not limited to, the early termination
and cancellation of this Agreement. If the parties hereto are unable to agree
whether any change or changes to this Agreement are necessary and proper, or as
to the terms of such changes, or whether this Agreement should be cancelled in
light of the occurrences described above, and such failure to reach agreement
shall continue for a period of 30 days following the commencement of the
consultations provided for by this Section 9.01(c), then this Agreement may be
cancelled by either AWA or Contractor upon providing the other party a minimum
of 90 days' written notice of such cancellation.
 
     Section 9.02 Termination
 
     (a) In addition to the foregoing provisions of this Article, this Agreement
may be cancelled or terminated by either AWA or Contractor if there is an
assignment of this Agreement or any of its rights, duties or obligations created
hereunder with respect to any party to this Agreement without the written
consent of the other party. In the event that this Agreement is assigned,
whether by operation of law or otherwise, without such consent having been given
in writing, the party not making the assignment shall have the right immediately
to terminate the Agreement by telegraphic or written notice to the other party.
If AWA merges, combines or consolidated with another carrier, or if
substantially all of AWA's assets are acquired by another carrier and the "HP"
designator code or the AMERICA WEST EXPRESS will thereafter not be used for the
services of AWA or such other carrier at the Hub, Contractor shall have the
right to use, in accordance with this Agreement, such replacement or substitute
designator code and related trademarks as are utilized by AWA or such other
acquiring or new carrier for its primary services at the Hub. A merger,
combination, or consolidation by or with another person, company or corporation
by Contractor shall be considered an assignment by Contractor; provided,
however, a merger, combination, or consolidation by or with a subsidiary or
affiliate of Contractor or with another corporation in which Contractor is the
surviving corporation and in which there is no substantial change in the
ownership or control of Contractor shall not be considered an assignment by
Contractor.
 
     (b) Recognizing that AWA is presently operating as a Chapter 11 company,
under reorganization, in the event that Contractor shall file a voluntary
petition in bankruptcy or that proceedings in bankruptcy shall be instituted
against it and such party shall be adjudged bankrupt, or that a court shall take
jurisdiction of such party and its assets pursuant to proceedings brought under
the provisions of any federal reorganization act, or that a receiver of such
party's assets shall be appointed and such taking or appointment shall not be
stayed or vacated within a period of 60 days, or if AWA should change to a
Chapter 7 proceeding or re-enter bankruptcy after its discharge from its current
bankruptcy, the other party may thereupon terminate this Agreement by 15 or more
days' prior written notice to the other party.
 
     (c) Except as otherwise provided herein, if either party shall fail to
perform, keep, and observe any of the terms, covenants or conditions herein
contained on the part of such party to be performed, kept or observed, the
non-breaching party may give the breaching party notice in writing to correct
such condition or cure such default and, if any such condition or default shall
continue for 30 days after the receipt of such notice by the breaching party
and, if within such period of time the breaching party has not prosecuted with
diligence the correction of such condition or default, the non-breaching party
may then terminate this Agreement upon 15 or more days' prior written notice,
and this Agreement shall thereupon cease and expire at the end of such 15 or
more days in the same manner and to the same effect as if it were the expiration
of the original term.
 
     (d) If either party is required by the FAA or DOT to suspend a substantial
portion of its operations for any safety reason, and has not resumed a major
portion of such operations hereunder within 30 days of suspension, the other
party may terminate this Agreement upon five or more days' prior written notice.
 
     (e) AWA, in addition to the other provisions of this section and Section
9.01 above, may terminate this Agreement upon not less than 30 days' written
notice to the other party hereto should any one of the following conditions
occur during the time this Agreement is in effect:
 
          (1) if, during any two consecutive calendar months during the life of
     this Agreement, Contractor's flight completion factor shall fall below 97%
     due to cancellations attributable to maintenance or operational
     deficiencies within Contractor's normal management control;
 
                                       11
<PAGE>   77
 
          (2) if, for any two consecutive calendar months during the life of
     this Agreement, Contractor's on-time performance falls below the lower of
     either: a.) 75 percent of arrivals within 15 minutes; or b.) AWA's actual
     on-time performance during the same period;
 
          (3) if, Contractor fails to comply with the trademark license
     provisions of Article 11 of this Agreement;
 
     (f) Either AWA or Contractor may terminate this Agreement without cause at
any time after the third year from the effective date hereof upon 180 days'
written notice to the other party.
 
     (g) Any early termination or cancellation of one or more of the provisions
of this Article 9 shall not be construed so as to relieve any party hereto of
any debts or monetary obligations to the other party that shall have accrued
hereunder prior to the effective date of such termination or cancellation.
 
     Section 9.03 Force Majeure
 
     Neither AWA nor Contractor shall be liable for any failure to perform under
this Agreement if such failure is due to causes beyond its control, including,
but not limited to, acts of God or the public enemy, fire, floods, epidemics,
quarantine or strikes; provided, however, that the foregoing shall not apply to
the obligations described under Article 7 of this Agreement.
 
ARTICLE 10 -- USE OF CONTRACTOR'S AIRCRAFT
 
     In the event that aircraft owned and/or operated by Contractor bearing the
AMERICA WEST EXPRESS are available and can be utilized without adversely
affecting in any manner the regular scheduled services operated pursuant to
Section 2, such aircraft may be used:
 
          (1) for non-scheduled planeload passenger charters; or
 
          (2) for scheduled or non-scheduled services limited to the
     transportation of freight and/or mail in markets other than the markets
     described in Section 2.01; or
 
          (3) on an emergency basis in operations in other parts of Contractor's
     system not covered by this Agreement.
 
ARTICLE 11 -- TRADEMARK LICENSE FOR OPERATIONS TO BE CONDUCTED
              BY CONTRACTOR PURSUANT TO THIS AGREEMENT
 
     Section 11.01 Grant of Trademark License
 
     Contractor will conduct all operations described in Section 2 above, and
any additional operations undertaken by subsequent amendment hereto under the
servicemark "AMERICA WEST EXPRESS" and shall utilize the AMERICA WEST EXPRESS
Servicemarks consisting of the exterior color decor and patterns on its aircraft
as prescribed by AWA. AWA hereby grants to Contractor a non-exclusive, non-
transferable license to use such AMERICA WEST EXPRESS Servicemarks in connection
with the services to be rendered by Contractor under this Agreement; provided,
however, that subject to the provisions of Section 202(b) hereof, at any time
during the life of this Agreement, AWA may alter, amend or revoke the license
hereby granted and require Contractor's use of any new or different AWA
Servicemarks in conjunction with the air transportation services provided
hereunder as AWA may determine in the exercise of its sole discretion and
judgment.
 
     Section 11.02 Terms and Conditions Governing Trademark License
 
     (a) Contractor hereby acknowledges AWA's ownership of the AWA Servicemarks,
further acknowledges the validity of the AWA Servicemarks, and agrees that it
will not do anything in any way to infringe or abridge AWA's rights in its
Servicemarks or directly or indirectly to challenge the validity of the AWA
Servicemarks.
 
                                       12
<PAGE>   78
 
     (b) Contractor agrees that, in providing the services to be provided under
this Agreement in conjunction with one or more of the AWA Servicemarks, it will
conform to such customer service standards (including professional appearance
guidelines and uniform standards; ground equipment appearance standards; ticket
counter and gate area image standards; and other reasonable quality control
measures) as may be reasonably prescribed by AWA either specifically in this
Agreement or by subsequent communications to Contractor. AWA shall have the
rights, through such agents or representatives as it may designate, to inspect
the services and standards being performed by Contractor under this Agreement,
and in the event that, in AWA's opinion, there has been some deviation from such
services and/or standards, Contractor agrees upon written notice from AWA to
rectify promptly any such deviation.
 
     (c) Contractor shall not, without AWA's express written consent, advertise
the services to be rendered hereunder, nor make use of the AWA Servicemarks
referred to in Section 11.01 above in any advertising. AWA shall have absolute
discretion to withhold its consent concerning any and all such advertising and
use of the AWA Servicemarks in advertising by Contractor. In the event AWA
approves the use of such AWA Servicemarks in any advertising, such advertising
shall identify AWA as the owner of such servicemark(s), and to the extent that
any mark is registered, shall so specify.
 
     (d) To the extent that Contractor is licensed to use the mark "AMERICA WEST
EXPRESS," Contractor will use said mark only in the mark "AMERICA WEST EXPRESS"
and then only in conjunction with the services specifically embraced by this
Agreement.
 
     (e) Nothing in this Agreement shall be construed to give Contractor the
exclusive right to use the AWA Servicemarks, or to abridge AWA's right to use
and/or to license its Servicemarks, and AWA hereby reserves the right to
continue use of the AWA Servicemarks as AWA may desire.
 
     (f) No term or provision of this Agreement shall be construed to preclude
the use of the servicemarks "AMERICA WEST EXPRESS" or the aircraft exterior
color decor and patterns by other individuals or corporations not covered by
this Agreement so long as such use does not place such persons so authorized in
direct competition with Contractor in the markets covered by this Agreement,
subject to Contractor's right of first refusal set forth in Article 2.
 
     (g) Should this Agreement be cancelled or otherwise terminated for any
reason as set forth in Article 9 hereof, the AWA Servicemarks shall revert to
AWA and shall not thereafter be used by Contractor in connection with any
operations of Contractor.

                             lease from GPA, during the period beginning not
                             later than June 30, 1995 and ending on June 30,
                             1999 (the "New Put Period"), up to eight new or
                             used aircraft of types consistent with the
                             Company's fleet plan and requirements (such right
                             being referred to herein as the "New Put Right").
 
                             Each lease entered into by the Company in
                             connection with the exercise by GPA of the New Put
                             Right shall provide for the payment by the Company
                             of a fair market rental for the related aircraft,
                             taking into consideration whether the related
                             aircraft is new or used, the specifications and
                             condition of the related aircraft and all
                             provisions of such lease that are relevant to the
                             overall cost to the Company of the related
                             aircraft, and determined at or about the time of
                             delivery of such aircraft to the Company on the
                             basis of operating lease rentals then prevailing in
                             the marketplace for comparable operating leases of
                             comparable aircraft to airlines of comparable
                             creditworthiness to the Company (at or about the
                             time of delivery of such aircraft to the Company
                             and without regard to the prior pendency of the
                             Case); each such lease will be for a lease term
                             determined as hereinafter described; and each such
                             lease shall have such other terms and provisions
                             and be in such form as is agreed upon by

                             the Company and GPA and attached to the agreement
                             between the Company and GPA pursuant to which GPA
                             is granted the New Put Right (such agreement being
                             referred to herein as the "New Put Agreement").
        
                             The specific number, types and delivery dates for
                             the aircraft which GPA will be entitled to deliver
                             to the Company (and which the Company will be
                             obligated to lease from GPA) in a particular year
                             during the New Put Period (as well as whether such
                             aircraft will be new or used aircraft) will be
                             determined on the basis of mutual agreement by the
                             Company and GPA, taking into account the Company's
                             fleet requirements for such year, the availability
                             to GPA for purposes of the New Put Agreement (in
                             light of applicable commercial constraints) of
                             aircraft during such year and the number of
                             aircraft theretofore delivered and thereafter
                             remaining to be delivered by GPA to the Company
                             under the New Put Agreement; provided, however,
                             that if, on or prior to the Mutual Agreement
                             Deadline (as such term is hereinafter defined) for
                             a particular year, the Company and GPA shall not
                             have mutually agreed upon the specific number,
                             types and delivery dates for the aircraft which GPA
                             will be entitled to deliver to the Company (and
                             which the Company will be obligated to lease from
                             GPA) during such year (as well as whether such
                             aircraft will be new or used aircraft), GPA will
                             have the right to put to the Company (and the
                             Company will be obligated to lease from GPA without
                             any necessity for further agreement of the Company)
                             up to the Maximum Number (as such term is
                             hereinafter defined) of aircraft for such year,
                             with (i) the specific types of such aircraft being
                             selected by GPA from among the Eligible Types (as
                             such term is hereinafter defined), (ii) such
                             aircraft being new or used aircraft as selected by
                             GPA, and (iii) the specific delivery dates for such
                             aircraft being selected by GPA, in each case, upon
                             at least 150 days' prior written notice by GPA to
                             the Company; and provided further, however, that,
                             unless GPA and the Company shall otherwise agree in
                             writing (whether by reason of mutual agreement
                             relevant to a particular year or otherwise), GPA
                             will not have the right to put to the Company more
                             than five used aircraft during the New Put Period.
                             As used herein, the term "Mutual Agreement
                             Deadline" means (i) with respect to each of 1995
                             and 1996, January 31, 1995, and (ii) with respect
                             to each ensuing year during the New Put Period,
                             January 1st of the preceding year. As used herein,
                             the term "Maximum Number" means (i) with respect to
                             1995, two, and (ii) with respect to each ensuing

                             herein, and unless GPA and the Company shall
                             otherwise agree in writing, the term "Eligible
                             Types" means, with respect to the types of aircraft
                             which GPA will be entitled to put to the Company
                             without the necessity for further agreement of the
                             Company, Boeing 737-300 aircraft, Boeing 757
                             aircraft and Airbus A320 aircraft.
 
                             The aircraft which GPA will be entitled to deliver
                             or put to the Company (and which the Company will
                             be obligated to lease from GPA) may be new or used
                             aircraft; provided, however, that unless GPA and
                             the Company shall otherwise agree in writing, GPA
                             will not have the right to deliver or put to the
                             Company more than five used aircraft during the New
                             Put Period; and provided further, however, that any
                             such aircraft which is an Airbus A320 aircraft will
                             (i) be new ex factory or like-new having no greater

(a) The stock options and warrants are included only in the periods in which
    they are dilutive.
 
(b) The calculation is submitted in accordance with Regulation S-K Item
    601(b)(11) although not required by footnote 2 to paragraph 14 of APB
    Opinion No. 15 because it results in dilution of less than 3%.
 
(c) The calculation is submitted in accordance with Regulation S-K Item
    601(b)(11) although it is contrary to paragraph 40 of APB Opinion No. 15
    because it produces an antidilutive result.
 
(d) 10,384,615 warrants are available for exercise and as such the EPS
    calculation should follow the modified treasury stock method. However since
    the exercise price of the warrants will not be determined until a later
    date, the EPS computation is presented without the effect of the exercise of
    the warrants for both primary and fully diluted earnings per share.

(*) For the purpose of computing the ratio of earnings to fixed charges,
    "earnings" consist of income (loss) before income taxes and extraordinary
    item plus fixed charges less capitalized interest. "Fixed charges" consist
    of interest expense including amortization of debt issuance costs, a portion
    of rent expense which is deemed to be representative of an interest factor,
    and capitalized interest. For the years ended December 31, 1990, 1991 and
    1992 earnings were insufficient to cover fixed charges by $83,070,000,
    $228,680,000 and $131,761,000 respectively.

Comptroller of the Currency
Administrator of National Banks
Midwestern District Office
2345 Grand Avenue, Suite 700
Kansas City, Missouri 64108
 
July 7, 1994
 
Mr. Robert T. Lund
Senior Vice President and General Counsel
American Bank National Association
101 East Fifth Street
St. Paul, Minnesota 55101-1860
 
Dear Mr. Lund:
 
     The Office of the Comptroller of the Currency (OCC) has received your
letter concerning the title change and the appropriate amendment to the Articles
of Association. The OCC has recorded that as of July 1, 1994, the title of
American National Bank and Trust Company, St. Paul, Minnesota, Charter No. 6828,
was changed to "American Bank National Association".
 
     As a result of Garn-St Germain Depository Institutions Act of 1982, the OCC
is no longer responsible for the approval of national bank name changes nor does
it maintain official records on the use of alternate titles. The use of other
titles or the retention of the rights to any previously used title is the
responsibility of the bank's board of directors. Legal counsel should be
consulted to determine whether or not the new title, or any previously used
title, could be challenged by competing institutions under the provisions of
federal or state law.
 
Sincerely,
 
/s/ JUDITH A. BOLLIG
