jurisdiction and as a result of such proceeding was or is subject to a judgment,
decree or final order enjoining future violations of, or prohibiting or
mandating activities subject to, federal or state securities laws or finding any
violation with respect to such laws.


Item 3.  Source and Amount of Funds or Other Consideration.

     The aggregate amount of funds required by Continental to purchase the Class
A Common, the Class B Common and the Warrants from the Company was $18,771,001.
All funds used by Continental to purchase the Class A Common, the Class B Common
and the Warrants were obtained from the working capital of Continental and no
part of the purchase price for the Class A Common, Class B Common or Warrants
consisted of borrowed funds.



Item 4.  Purpose of Transaction.

     The purpose of the purchase of the Class A Common, Class B Common and
Warrants by Continental is for general investment purposes.

     Continental intends to review continuously its equity position in the
Company.  Depending upon future evaluations of the business prospects of the
Company and upon other developments, including, but not limited to, general
economic and business conditions and money market and stock market conditions,
Continental may determine to increase or decrease its equity interest in the
Company by acquiring additional shares of Class A Common, Class B Common or
Warrants or by disposing of all or a portion of its holdings of Class A Common,
Class B Common or Warrants, subject to any applicable legal and contractual
restrictions on its ability to do so.

     Continental has acquired its interests in the Class A Common, Class B
Common and Warrants as a result of the assignment by AmWest Partners, L.P.
("AmWest") of certain rights granted to AmWest under the Third Revised
Investment Agreement (the "Investment Agreement") between AmWest and America
West Airlines, Inc., prior to its reorganization ("Old America West"), including
AmWest's right to purchase Class A Common, Class B Common and the Warrants from
the Company on the Effective Date.

     AmWest and Old America West entered into the Investment Agreement on April
21, 1994.  Pursuant to the Investment Agreement, AmWest agreed, in connection
with and as part of the Plan, to acquire certain voting securities, debt
securities and warrants of the Company.  In addition, pursuant to the Investment
Agreement, the Company, AmWest, the Official Creditors' Committee and the
Official Equity Committee agreed to appoint a new Board of Directors for the
Company, to amend the charter and by-laws of the Company and to enter into
certain other agreements described in Item 6 below.  Following the successful
completion of the transactions contemplated by the Investment Agreement on
August 25, 1994 (including the assignment by AmWest of its rights under the
Investment Agreement to certain parties,

                                      11

including Continental), certain affiliates of Continental, including TPG
Partners, L.P. ("TPG"), TPG Parallel I, L.P. ("TPG Parallel") and Air Partners
II, L.P. ("Air Partners II") (TPG, TPG Parallel and Air Partners II,
collectively, the "TPG Parties") own a controlling interest in the Company.  A
copy of the Investment Agreement is filed as an exhibit hereto and incorporated
herein by reference.

     Except as set forth herein, Continental does not have any plans or
proposals which would relate to or result in:

     (a)  The acquisition of additional securities of the Company, or the
          disposition of securities of the Company;

     (b)  An extraordinary corporate transaction, such as a merger,
          reorganization or liquidation, involving the Company or any of its
          subsidiaries;

     (c)  A sale or transfer of a material amount of assets of the Company or of
          any of its subsidiaries;

     (d)  Any change in the present board of directors or management of the
          Company, including any plans or proposals to change the number or term
          of directors or to fill any existing vacancies on the board;

     (e)  Any material change in the present capitalization or dividend policy
          of the Company;

     (f)  Any other material change in the Company's business or corporate
          structure;

     (g)  Changes in the Company's charter, bylaws or instruments corresponding
          thereto or other actions which may impede the acquisition of control
          of the issuer by any person;

     (h)  Causing a class of securities of the Company to be delisted from a
          national securities exchange or to cease to be authorized to be quoted
          in an inter-dealer quotation system of a registered national
          securities association;

     (i)  A class of equity securities of the Company becoming eligible for
          termination of registration pursuant to Section 12(g)(4) of the
          Securities Exchange Act of 1934 (the "Exchange Act"); or

     (j)  Any action similar to any of those enumerated above.

Item 5.  Interest in Securities of the Issuer.

     (a) - (b) At the date hereof, Continental has the sole power to vote and
dispose of 325,505 shares of the Class A Common, 1,508,234 shares of the Class B
Common, and 802,860 Warrants.  The Warrants entitle holders to purchase one
share of the Class B Common at a price of $12.74 per share, subject to
confirmation of such price by the Bankruptcy Court pursuant to a final order and
to certain adjustments.  The Class A Common held by Continental represents
approximately 27.1% of the 1,200,000 shares of Class A Common outstanding as of
August 31, 1994, based on information provided by the Company. The Class B
Common held by Continental represents approximately 3.4% of the 43,925,000
shares of Class B Common outstanding as of August 31, 1994, based on information
provided by the Company. The Warrants held by Continental represent
approximately 7.7% of the 10,384,615 Warrants outstanding as of August 31, 1994,
based on information provided by the Company. Assuming exercise of the Warrants,
the Class B Common and Warrants held by Continental represent approximately 5.2%
of the 44,727,860 shares of Class B Common which would be assumed to be
outstanding upon such exercise.

     As set forth in Item 5(d) and 6, the TPG Parties have certain
understandings and agreements regarding the voting and disposition of the
securities of the Company held by them with GPA Group plc, an Irish public
limited company ("GPA"), Continental and Mesa Airlines, Inc., a New Mexico
corporation ("Mesa"). As a result of these agreements and understandings, the
TPG Parties together with each of GPA, Continental and Mesa comprise a group
within the meaning of Section 13(d)(3) of the Exchange Act, and each may be
deemed to beneficially own the securities of the Company owned by the other.
Information concerning the ownership of Class A Common, Class B Common and
Warrants by each of the TPG Parties, GPA and Mesa is contained in separate
Schedules 13D being filed by each of the TPG Parties, GPA and Mesa. As a group,
such parties beneficially own 1,200,000 shares of the Class A
Common, 9,604,429 shares of the Class B Common, and 4,897,538 Warrants. The
aggregate amount of Class A Common beneficially owned by the group represents
100% of the 1,200,000 shares of Class A Common outstanding as of August 31,
1994, based on information provided by the Company. The aggregate amount of
Class B Common beneficially owned by the group represents approximately 21.9% of
the 43,925,000 shares of Class B Common outstanding as of August 31, 1994,
based on information provided by the Company. The aggregate amount of Warrants
beneficially owned by the group represents approximately 47.2% of the 10,384,615
Warrants outstanding as of August 31, 1994, based on information provided by the
Company. Assuming exercise of the Warrants, the aggregate amount of Class B
Common and Warrants beneficially owned by the group represents approximately
29.7% of the 48,822,538 shares of Class B Common which would be assumed to be
outstanding upon such exercise.

     Except as described herein, Continental does not have the sole or shared
voting power to vote or the sole or shared power to dispose of any shares of
Class A Common, Class B Common or any of the Warrants.

     To the knowledge of Continental, none of the individuals named in Item 2
has the sole or shared power to vote or the sole or shared power to dispose of
any shares of Class A Common, Class B Common, or of any Warrants.

     (c) Except as stated herein, no transactions in shares of Class A Common,
Class B Common or Warrants were effected during the past 60 days by Continental
or to the best of its knowledge, any of the individuals identified in Item 2.

following is a brief description of the Priority Distribution Agreement, and is
qualified in its entirety by reference to such agreement, a copy of which is

     The Priority Distribution Agreement provides that the TPG Parties will

the securities of the Company covered by such agreement (including certain
shares of Class A Common and Class B Common), if such sharing of proceeds is
necessary to ensure that Continental receives a specified rate of return on its
investment in the securities of the Company.  Pursuant to the Priority
Distribution Agreement, the TPG Parties have also granted Continental a right of
first refusal with regard to the sale by any of the TPG Parties of any of the
securities covered by such agreement.

     (e)  Not applicable.

Item 6.  Contracts, Arrangements, Understandings or
         Relationships With Respect to Securities of the Issuer.

     On August 25, 1994, AmWest Genpar Inc., a Texas corporation ("AmWest
Genpar"), Apcal, L.P., a Texas limited partnership ("Apcal"), and Mesa entered
into an agreement (the "Termination Agreement"), pursuant to which AmWest was
dissolved.  Apcal and Mesa were limited partners of AmWest; AmWest Genpar was
its general partner.  The limited partners of Apcal included TPG and
Continental, and TPG and Continental have agreed to and acknowledged certain
provisions of the Termination Agreement and have (together with the other TPG
Parties and Mesa) additionally entered into certain related assignment and
assumption agreements with AmWest (copies of which agreements are attached as an
exhibit hereto and incorporated herein by this reference).  The following is a
brief description of the Termination Agreement and is qualified in its entirety
by reference to such agreement, a copy of which is filed as an exhibit hereto
and incorporated herein by reference.

                                      14

<PAGE>
 
     The Termination Agreement provides that AmWest assign to each of AmWest
Genpar, Apcal and Mesa its rights and obligations under the Investment Agreement
to purchase from the Company on the Effective Date certain shares of Class A
Common, Class B Common and Warrants and that each of AmWest Genpar and Apcal
assign such rights and obligations to certain of their affiliates (including the
TPG Parties and Continental) in accordance with certain agreements entered into
between such affiliates and AmWest. The Termination Agreement further provides
that each of AmWest Genpar, Apcal and Mesa (and each of their respective
affiliates, including Continental, to which rights to acquire securities have
been assigned) assume all obligations of AmWest under the Investment Agreement
in connection with the purchase of such securities.  As described below, the
Termination Agreement also contains certain provisions concerning the assignment
and assumption of certain rights of AmWest under the Stockholders' Agreement and
the Registration Rights Agreement (each as defined below).

     Pursuant to the Termination Agreement, AmWest has assigned to TPG its right
under the Stockholders' Agreement to designate certain directors of the Company
and their replacements, if any, provided that for as long as Mesa owns
securities representing at least 2% of the aggregate voting power of the
outstanding voting equity securities of the Company, TPG has agreed with Mesa to
cause one person identified by Mesa, who shall be reasonably acceptable to TPG,
to be included among TPG's designated directors.  In addition, each of the
parties to the Termination Agreement and their respective partners and
affiliates, including Continental, have agreed to assume certain of the
obligations of AmWest under the Stockholders' Agreement concerning the voting
and disposition of Class A Common and Class B Common and to be bound by the
terms of the Stockholders' Agreement as they relate to such actions.  The
Termination Agreement also provides that AmWest assign to TPG certain of its
rights under the Registration Rights Agreement (including the right to issue a
notice of demand), subject to certain notice and consent requirements.

     On August 25, 1994, AmWest, the Company, Lehman Brothers Inc., a Delaware
corporation ("Lehman"), Belmont Fund L.P., a Delaware limited partnership
("Belmont"), Fidelity Copernicus Fund, L.P., a Delaware limited partnership
("Copernicus"), and Belmont Capital Partners II, L.P., a Delaware limited
partnership ("Belmont II"), entered into a Registration Rights Agreement (the
"Registration Rights Agreement").  The following is a brief description of the
Registration Rights Agreement, and is qualified in its entirety by reference to
such agreement, a copy of which is filed as an exhibit hereto and incorporated
herein by reference.

     Pursuant to the Registration Rights Agreement, the Company has agreed to
file a shelf registration statement with respect to the securities issued or
issuable to each of the parties thereto and their respective affiliates and to
maintain effective such shelf registration statement for a period of three years
from the Effective Date (the "Shelf Period").  After the Shelf Period, AmWest
(or its designated assignee, which is TPG) may provide the Company with a notice
of demand to register under the Securities Act of 1933 such securities as are
included in such notice of demand or otherwise includable pursuant to the
Registration Rights Agreement,  for disposition in accordance with the terms of
such notice of demand.  The Registration Rights

                                      15


<PAGE>
 
Agreement also provides that the parties (including Continental) may include
securities held by them in any registration of equity securities by the Company
(whether or not on its own behalf), pursuant to certain limitations on such
inclusion in the event that the managing underwriter of any such registration
informs the Company of its belief that the amount of securities requested to be
included in such registration exceeds the amount which can be sold in an
acceptable price range.  The Registration Rights Agreement also provides that
the Company shall undertake certain specified actions with regard to the
registration and offering of any securities covered by the Registration Rights
Agreement and, pay stated amounts of liquidated damages to holders of
registrable securities in the event of the suspension or ineffectiveness of the
shelf registration statement covering such securities.

     On August 25, 1994, AmWest, GPA, the Company and certain other parties
entered into a Stockholders' Agreement (the "Stockholders' Agreement"). The
following is a brief description of the Stockholders' Agreement, and is
qualified in its entirety by reference to such agreement, a copy of which is
filed as an exhibit hereto and incorporated herein by reference.

     The Stockholders' Agreement has a term of approximately three years,
commencing on August 25, 1994 and ending on the date of the first annual meeting
of the Company occurring after August 25, 1997. Pursuant to the Stockholders'
Agreement, the parties have agreed that the Board of Directors of the Company
shall consist of up to 15 members to be designated as follows: nine members to
be designated by AmWest or its designated assignees (which assignee is TPG);
three members to be designated by the Official Creditors' Committee, provided
that each such member be reasonably acceptable to AmWest or its designated
assignees; one member to be designated by the Official Equity Committee,
provided that such member be reasonably acceptable to AmWest or its designated
assignees; one member to be designated by the Board of Directors of Old America
West, provided that such member be reasonably acceptable to AmWest or its
designated assignees; and one member to be designated by GPA for so long as GPA
shall own 2% of the voting equity securities of the Company, provided that such
member be reasonably acceptable to AmWest or its designated assignees. The Board
of Directors of the Company has been designated in accordance with these
provisions of the Stockholders' Agreement. The parties to the Stockholders'
Agreement, including Continental, have agreed to vote, or recommend the voting
of, the shares of Class A Common and Class B Common held by each of them in a
manner such that the provisions of the Stockholders' Agreement will be given
effect during its term and in order that both the election and removal of
directors will be consistent with its provisions.

     The Stockholders' Agreement also provides that, during its term, the
affirmative vote of a majority of the voting power of the outstanding shares of
each of the Class A Common and Class B Common entitled to vote (excluding any
shares owned by AmWest or any of its affiliates (including Continental) but not,
however, excluding shares owned, controlled or voted by Mesa or any of its
transferees or affiliates that are not otherwise affiliates of AmWest) voting as
a single class, shall be required to approve, adopt or authorize: (i) any merger
or consolidation of the Company with or into AmWest or any affiliate of AmWest,
(ii) any sale,

                                      16

<PAGE>
 
lease, exchange, transfer or other disposition of all or any substantial part of
the assets of the Company to AmWest or any affiliate of AmWest, (iii) any
transaction as a result of which AmWest or any affiliate of AmWest will, as
result of the issuance of voting securities of the Company (or securities
convertible or exchangeable for such voting securities) acquire an increased
percentage of the Company's voting securities, subject to certain exceptions and
(iv) any related series or combination of transactions having the same direct or
indirect effect as any of the foregoing. In addition, the Stockholders'
Agreement obligates AmWest, its partners and affiliates, including Continental,
not to (a) sell or otherwise transfer any shares of Class A Common or Class B
Common, if, after such transaction, the total number of shares of Class B Common
beneficially owned by the transferor is less than twice the number of shares of
Class A Common beneficially owned by the transferor (unless such transaction
results in the sale or transfer of all of such party's Class A Common and Class
B Common); and (b) sell or transfer, in a single transaction or related series
of transactions, shares of Class A Common and Class B Common representing 51% or
more of the combined voting power of all shares of Common Stock of the Company
then outstanding without the consent of the Company, pursuant to an affirmative
vote of not less than 75% of its directors and subject to certain enumerated
exclusions (including, without limitation, transfers to affiliates and sales in
connection with a public offering or tender offer for all shares of common stock
and for the benefit of all holders of Class B Common on a pro rata basis at the
same price and on the same economic terms).

     On August 25, 1994, AmWest and GPA entered into a Voting Agreement (the
"GPA Voting Agreement").  The following is a brief description of the GPA Voting
Agreement, and is qualified in its entirety by reference to such agreement, a
copy of which is filed as an exhibit hereto and incorporated herein by
reference.

     The GPA Voting Agreement provides that GPA shall vote for the nominees of
AmWest or its designated assignee to the Company's Board of Directors and that
AmWest (and its affiliates or assignees, including Continental, who receive
Class A Common or Class B Common as a result of an assignment by AmWest, subject
to certain enumerated exceptions) shall vote for GPA's nominees to the Company's
Board of Directors, in each case, for so long as AmWest or its affiliates own 5%
of the voting equity securities of the Company and GPA owns at least 2% of the
voting equity securities of the Company or until August 25, 2004, whichever
comes first.  In addition, the GPA Voting Agreement provides that AmWest shall
not transfer or assign any voting equity securities of the Company to Mesa, if
after giving effect to any such transfer or assignment, Mesa shall hold 7% or
more of the combined voting power of all such securities then outstanding.

     On August 25, 1994, Continental and the TPG Parties entered into a Priority
Distribution Agreement, which is described in Item 5(d) above.

     There are no other contracts, understandings or agreements with respect to
the securities of the Company between Continental and the other persons
identified in Item 2 and any other parties.

on or before the Outside Date, Investor nevertheless shall be required to
consummate the Investment  and, to that end, agrees to timely make such
adjustment to the composition of its partnership and to the Alliance Agreements
as required to resolve such antitrust objection; provided, however, that nothing
in this paragraph (b) shall affect the rights of the Company under Section 9(g)
or obligate the Company to enter into or approve any adjustment or modification
of the Alliance Agreements which, in the Company's reasonable judgment, is

<PAGE>
 
It is understood and agreed that this Agreement shall not create any obligation
of, or restriction upon, the Company or Investor or the partners of Investor
that would violate applicable provisions of law or regulation relating to
ownership or control of a U.S. air carrier.  At all times after the Effective
Date, the certificate of incorporation of the Company shall provide that, in the
event persons who are not U.S. citizens shall own (beneficially or of record) or
have voting control over shares of Common Stock, the voting rights of  such
persons shall be subject to automatic suspension as required to ensure that the
Company is in compliance with applicable provisions of law or regulation
relating to ownership or control of a U.S. air carrier.

        SECTION 13. Representations and Warranties of the Company.  The
Company represents and warrants to Investor as follows:

        (a) The Company has complied in all material respects with the terms of
    all orders of the Bankruptcy Court in respect of the Investment, this
    Agreement and the Procedures Agreement.

        (b) The Company has delivered to Investor copies of the audited balance
    sheets of the Company as of December 31, 1992 and the statements of income,
    stockholders' equity and cash flows for the years then ended, together with
    the notes thereto.  Such financial statements, and when delivered to
    Investor the financial statements of the Company referred to in Section 8(g)
    will, present fairly, in accordance with generally accepted accounting
    principles (applied on a consistent basis except as disclosed in the
    footnotes thereto), the financial position and results of operations of the
    Company as of the dates and for the periods therein set forth.

        (c) When delivered to Investor, the unaudited financial statements of
    the Company referred to in Section 15(b)(ii) will (i) present fairly, in
    accordance with generally accepted accounting principles (applied on a
    consistent basis except as disclosed therein and subject to normal year- end
    audit adjustments), the financial position and results of operations of the
    Company as of the date and for the period therein set forth, it being
    understood and agreed, however, that the foregoing representation relating
    to conformity with generally accepted accounting principles is being made
    only to the extent such principles are applicable to interim unaudited
    reports and (ii) reflect a financial position and results of operations not
    materially worse than those set forth in the pro forma financial statements
    contained in Plan 9.

                                       23

<PAGE>
 
        (d) The Projections and the Monthly Targets were prepared in good faith
    on a reasonable basis, and when prepared represented the Company's best
    judgment as to the matters set forth therein, taking into account all
    relevant facts and circumstances known to the Company.  Nothing has come to
    the Company's attention since the dates on which the Projections and the
    Monthly Targets, respectively, were prepared which causes the Company to
    believe that any of the projections and other information contained therein
    were misleading or inaccurate in any material respect as of such dates.  It
    is specifically understood and agreed that the delivery of the Projections
    and the Monthly Targets shall not be regarded as a representation, warranty
    or guarantee that the particular results reflected therein will in fact be
    achieved or are likely to be achieved.

        (e) No written statement, memorandum, certificate, schedule or other
    written information provided (or to be provided) to Investor or any of its
    representatives by or on behalf of the Company in connection with the
    transactions contemplated hereby, when viewed together with all other
    written statements and information provided to Investor and its
    representatives by or on behalf of the Company, in light of the
    circumstances under which they were made, (i) contains or will contain any
    materially misleading statement or (ii) omits or will omit to state any
    material fact necessary to make the statements therein not misleading.

        (f) The board of directors of the Company has approved the Investment
    and Investor's acquisition of Securities hereunder for purposes of, and in
    accordance with the provisions and requirements of, Section 203(a)(1) of the
    General Corporation Law of the State of Delaware and, as a consequence,
    Investor will not be subject to the provisions of such Section with respect
    to any "business combination" between Investor and the Company (as such term
    is defined in said Section 203).

        SECTION 14. Representations and Warranties of Investor.  Investor
represents and warrants to the Company as follows:

construed in accordance with the laws of the State of Arizona, without reference
to principles of

                                       27

<PAGE>
 
conflicts or choice of law under which the law of any other jurisdiction would
apply.

        SECTION 21. Amendment.  This Agreement may only be amended, waived,
supplemented or modified by a written instrument signed by authorized
representatives of Investor and the Company.  Investor may extend the time for
satisfaction of the conditions set forth in Section 8 (prior to or after the
relevant date) by notifying the Company in writing.  The Company may extend the
time for satisfaction of the conditions set forth in Section 9 (prior to or
after the relevant date) by notifying Investor in writing.

        SECTION 22. No Third Party Beneficiary.  This Agreement and the
Procedures Agreement are made solely for the benefit of the Company and Investor
and their respective permitted assigns, and no other Person (including, without
limitation, employees, stockholders and creditors of the Company) shall have any
right, claim or cause of action under or by virtue of this Agreement or the
Procedures Agreement, except to the extent such Person is entitled to protection
as contemplated by Section 28(b) or to expense reimbursement pursuant to the
Procedures Agreement or may assert a claim for indemnity pursuant to the
Procedures Agreement.

        SECTION 23. Assignment.  Except as otherwise provided herein, Investor
may assign all or part of its rights under this Agreement to any of its partners
(each of whom may assign all or part to its Affiliates) or to any fund or
account managed or advised by Fidelity Management Trust Company or any of its
Affiliates and may assign any Securities (or the right to purchase any
Securities) to any lawfully qualified Person or Persons, and the Company may
assign this Agreement to any Person with which it may be merged or consolidated
or to whom substantially all of its assets may be transferred in facilitation of
the consummation of the Plan and the effectuation of the issuance and sale of
the Securities as contemplated hereby or by the Related Agreements.  None of
such assignments shall relieve the Company or Investor of any obligations
hereunder, under the Procedures Agreement or under the Related Agreements.

        SECTION 24. Counterparts.  This Agreement may be executed by the
parties hereto in counterparts and by telecopy, each of which shall be deemed to
constitute an original and all of which together shall constitute one and the
same instrument.  With respect to signatures transmitted by telecopy, upon

party shall promptly be substituted for its facsimile.

        SECTION 25. Invalid Provisions.  If any provision of this

                                       28

<PAGE>
 
Agreement is held to be illegal, invalid or unenforceable under any present or
future laws, rules or regulations, and if the rights or obligations of Investor
and the Company under this Agreement will not be materially and adversely
affected thereby, (a) such provision will be fully severable, (b) this Agreement
will be construed and enforced as if such illegal, invalid or unenforceable
provision had never comprised a part hereof, (c) 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 (d) 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.  If the rights and obligations of
Investor or the Company will be materially and adversely affected by any such
provision held to be illegal, invalid or unenforceable, then unless such
provision is waived in writing by the affected party in its sole discretion,
this Agreement shall be null and void.

        SECTION 26.  Tagalong Rights.  On the Effective Date, Investor shall
enter into a written agreement for the benefit of all holders of Class B Common
(other than Investor and its Affiliates) whereby Investor shall agree, for a
period of three years after the Effective Date, not to sell, in a single
transaction or related series of transactions, shares of Common Stock
representing 51% or more of the combined voting power of all shares of Common
Stock then outstanding unless such holders 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 Investor;
provided, however, that such obligation of Investor shall not apply to any sale
of shares of Common Stock made by Investor (i) to any Affiliate of Investor,
(ii) to any Affiliate of Investor's partners, (iii) pursuant to a bankruptcy or
insolvency proceeding, (iv) pursuant to judicial order, legal process, execution
or attachment, (v) in a widespread distribution registered under the Securities
Act of 1933, as amended ("Securities Act") or (vi) in compliance with the volume
limitations of Rule 144 (or any successor to such Rule) under the Securities
Act.

        SECTION 27. Stock Legend.  All securities issued to Investor pursuant
to the Plan shall be conspicuously endorsed with an appropriate legend to the
effect that such securities may not be sold, transferred or otherwise disposed
of except in compliance with (i) Section 26 and (ii) applicable securities laws.

        SECTION 28.  Directors' Liability and Indemnification.  (a)

                                       29

<PAGE>
 
Upon, and at all times after, consummation of the Plan, the certificate of
incorporation of the Company shall contain provisions which (i) eliminate the
personal liability of the Company's former, present and future directors for
monetary damages resulting from breaches of their fiduciary duties to the
fullest extent permitted by applicable law and (ii) require the Company, subject
to appropriate procedures, to indemnify the Company's former, present and future
directors and executive officers to the fullest extent permitted by applicable
law.  In addition, upon consummation of the Plan, the Company shall enter into
written agreements with each person who is a director or executive officer of
the Company on the date hereof providing for similar indemnification of such
person and providing that no recourse or liability whatsoever with respect to
this Agreement, the Procedures Agreement, the Related Agreements, the Plan or
the consummation of the transactions contemplated hereby or thereby shall be
had, directly or indirectly, by or in the right of the Company against such
person.  Notwithstanding anything contained herein to the contrary, the

        (b) Investor agrees, on behalf of itself and its partners, that no
recourse or liability whatsoever (except as provided by applicable law for
intentional fraud, bad faith or willful misconduct) shall be had, directly or
indirectly, against any person who is a director or executive officer of the
Company on the date hereof with respect to this Agreement, the Procedures
Agreement, the Related Agreements, the Plan or the consummation of the
transactions contemplated hereby or thereby, such recourse and liability, if
any, being expressly waived and released by Investor and its partners as a
condition of, and in consideration for, the execution and delivery of this
Agreement.

construe the provisions of this Agreement.

        SECTION 30.  Interpretation.  In this Agreement, unless a contrary
intention appears, (i) the words "herein", "hereof" and "hereunder" and other
words of similar import refer to this Agreement as a whole and not to any
particular Section or other subdivision and (ii) reference to any Section means
such Section hereof.  The Section headings herein are for convenience only and
shall not affect the construction hereof.  No provision of this Agreement shall
be interpreted or construed against either party solely because such party or
its legal representative drafted such

                                       30

<PAGE>
 
provision.

        SECTION 31.  Termination.  This Agreement shall terminate concurrently

                        PRIORITY DISTRIBUTION AGREEMENT
                        -------------------------------


        PRIORITY DISTRIBUTION AGREEMENT, dated as of August 25, 1994, by and
among TPG Partners, L.P., a Delaware limited partnership ("TPG Partners"), TPG
Parallel I, L.P., a Delaware limited partnership ("Parallel"), Air Partners II,
L.P., a Texas limited partnership ("APII", and, collectively with TPG Partners
and Parallel, "TPG") and Continental Airlines, Inc., a Delaware corporation
("Continental", and collectively, the "Parties").

        WHEREAS, each of the Parties owns the amounts, set forth on Exhibit "A"
attached hereto, of shares of Class A and Class B Common Stock issued by America
West Airlines, Inc. or its successor as reorganized pursuant to Chapter 11 of
the United States Bankruptcy Code;

        WHEREAS, each of the Parties desires to share with the other Parties, in
the manner set forth in this Agreement, certain of the proceeds of the shares of
Class A and Class B Common Stock set forth on the attached Exhibit "A".

        NOW, THEREFORE, in consideration of the premises and the mutual
representations, covenants and agreements set forth in this Agreement, the
parties agree as follows:

        1.  Definitions.  As used in this Agreement, the following terms shall
have the following meanings:

        (a)  "Basic Threshold Amount" shall mean the amount
 necessary to ensure
that Continental, from all Deemed Proceeds or actual proceeds, as the case may
be, and nonrefunded payments to Continental by TPG hereunder, has been returned
its Cost Basis in all of its Securities plus its 10% Return.

        (b)  "Class A Common Stock" and "Class B Common Stock" and "Warrants"
shall mean the shares of Class A common stock, Class B common stock and warrants
to acquire Class B common stock issued by America West Airlines, Inc. (or its
successor as reorganized pursuant to Chapter 11 of the United States Bankruptcy
Code, "AWA") that are reflected on Exhibit "A", as adjusted for any sales or
conversions thereof or any stock dividends or splits with respect thereto.  Any
shares of Class A or Class B common stock or warrants of AWA acquired by any of
the Parties after the date of this Agreement (other than shares of Class B
common stock acquired pursuant to the exercise of Warrants) shall not constitute
shares of Class A Common Stock, Class B Common Stock or Warrants subject to this
Agreement.

        (c)  "Cost Basis" shall mean the per Security price set forth on Exhibit
A hereto.

<PAGE>
 
        (d)  "Securities" shall mean collectively, the Class A Common Stock, the
Class B Common Stock and the Warrants.

        (e)  "Specified Percentage" shall mean 200%, provided that if the
Securities owned by Continental and TPG are either (i) covered by a currently
effective registration statement filed with the Securities and Exchange
Commission (the "SEC"), under the Securities Act of 1933 (the "Securities Act")
or (ii) all able to be sold promptly pursuant to Rule 144 promulgated by the SEC
under the Securities Act, then the Specified Percentage shall be 150%.

        (f)  "10% Return" shall mean the amount required to return (with either
Deemed Proceeds or actual proceeds, as the case may be) to Continental or TPG,
as the case may be, a 10% per year return (compounded annually) on the
unreturned (either with Deemed Proceeds or actual proceeds as the case may be)
Cost Basis of the Securities in question.

     (g)  "Value" shall mean:

          (A)  if Securities are listed on a national securities exchange or on
the National Market System Quotations, or are traded in the over-the-counter
market and reported in the National Association of Securities Dealers' Automated
Quotation System, the last sales price of the Securities, on the valuation date,
or in the absence of a sale on such date, the last bid price on the valuation
date; and

          (B)  if Securities are not listed or traded in the manner specified in
clause (A) above, the fair market value, as reasonably determined by TPG of the
Securities.

     2.  Proceeds from TPG Sales.

        Each time that TPG sells all or any portion of its Securities ("Actually
Sold Securities"), Continental shall be deemed to sell a corresponding portion
(on a percentage basis) of its similar type of Securities ("Deemed Sold
Securities") for the same price per share as received by TPG ("Deemed Proceeds")
(with the understanding that Continental's 10% Return shall be deemed to have
continued to accrue on the Deemed Sold Securities through the date of the deemed
sale for purposes of such determination).  TPG agrees to utilize the proceeds
from its Actually Sold Securities as follows:

     (i)  First, to pay Continental any 10% Return accrued with respect to all
          of its Deemed Sold Securities and not previously returned with Deemed
          Proceeds or actual sale proceeds (as applicable) or nonrefunded prior
          payments by TPG hereunder;

                                       2

<PAGE>
 
    (ii)  Second, to retain amounts sufficient to receive a 10% Return accrued
          with respect to all of its Actually Sold Securities and not previously
          retained by TPG in connection with previous actual sales or refunded
          to TPG by Continental hereunder;

   (iii)  Third, to pay Continental amounts, if any, necessary to ensure that
          Continental has received from Deemed Proceeds or actual sale proceeds
          (as applicable) and nonrefunded prior payments by TPG hereunder both
          its 10% Return and its Cost Basis with respect to its Deemed Sold
          Securities; and

    (iv)     Finally, to retain any excess.

        Notwithstanding anything contained herein to the contrary, the proceeds
and timing of any actual sales of Securities by Continental shall be utilized
instead of the Deemed Proceeds and timing of the deemed sale of the
corresponding Deemed Sold Securities (i.e., the first Securities actually sold
shall be matched against the first Securities deemed sold) to the extent both
(i) actual sales preceded the deemed sales and (ii) utilization of actual sales
would reduce the amount owed by TPG hereunder or increase the amounts refundable
by Continental to TPG hereunder.

        For example, assume (i) the Parties acquired their Securities on 1/1/94,
(ii) TPG acquired twice the amount of Securities as did Continental, (iii) each
Party had a Cost Basis of $10 per share and (iv) the Parties actually sold
Securities as follows:

For purposes of this Agreement, Continental would be deemed to have sold the

     At any time that an actual sale by TPG of its remaining Securities for
their Value would net Continental Deemed Proceeds and required payments by TPG
to Continental hereunder of less than the Specified Percentage of Continental's
Basic Threshold Amount, then Continental shall have the right to require TPG (by
written notice to TPG) to pay (and TPG shall pay) in cash, within fifteen (15)
business days, the amount which TPG would have been required to pay pursuant to
this Section 2 if TPG actually sold all of its remaining Securities for their
Value as of the date TPG receives such notice; provided, however, that the
provisions of the last sentence of this paragraph will continue to apply if,
thereafter, TPG retains any Securities.  If any amounts are paid by TPG to
Continental hereunder and, upon the deemed sale of Continental Securities,
Continental has received Deemed Proceeds and payments from TPG hereunder in
excess of its 10% Return and its Cost Basis with respect to its Deemed Sold
Securities, then Continental shall within five business days of such deemed sale
repay TPG amounts paid to it to the extent of such excess.  For purposes of this
Agreement, proceeds from the sale of Class B Common Stock acquired by
Continental or TPG pursuant to the exercise of Warrants shall be determined by
deducting any exercise price paid therefor and TPG shall be entitled to first
recover any such exercise price prior to any such proceeds being subject to this
Agreement.

     3.   Certain Rights of First Refusal.  TPG shall not sell shares without
first notifying Continental.  Continental shall have the right of first refusal
to purchase all (but not less than all) of the Securities ("Offered Shares")
owned by TPG that TPG has notified Continental it desires to sell ("Sale
Notice").  Continental shall have the right to purchase the Offered Shares for
either (i) if such Offered Shares are not proposed to be sold on a public
exchange, on the same terms and conditions that the Offered Shares would have
been sold, or (ii) if such Offered Shares are proposed to be sold on a public
exchange, for the last sales price per share on the date on which Continental
issued its written notice described in the following sentence (or if there were
no sales on such date, the last sales price per share preceding such date).
Continental may exercise this right only if (x) it provides written notice to
each of the other Parties of its intention to do so within five (5) business
days after its receipt of the Sale Notice, and (y) it purchases all of such

                                       4

<PAGE>
 
Offered Shares on or before the tenth (10th) business day following such written
notice.

     4.   Notice.

for next day delivery with an overnight courier, (iii) forty-eight (48) hours
after being deposited in the United States mail or (iv) three (3) hours after
being telecopied or otherwise transmitted and receipt has been confirmed.

     (d)  The Parties shall have the right from time to time, and at any time,
during the term of this Agreement, to change their respective addresses and each
shall have the right to specify as his or its address any other address by
giving to the other parties at least thirty (30) days written notice thereof, in
the manner prescribed in Section 11(b); provided, that to be effective, any such
notice must be actually received (as evidenced by a return receipt).

     5.  GOVERNING LAW.  THE RIGHTS AND OBLIGATIONS OF THE PARTIES SHALL BE
INTERPRETED, CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
TEXAS.

     6.  Entire Agreement.  This Agreement, including all exhibits to this
Agreement and, if any, exhibits to such exhibits, contains the entire agreement
among the Parties relative to the matters contained in this Agreement.

     7.  Waiver.  No consent or waiver by any Party to or for any breach or
default by any other party in the performance by such other party of his or its
obligations under this Agreement shall be effective unless expressly set forth
in writing or be deemed or construed to be a consent or waiver to or of any
other breach or default in the performance by such other party of the same or
any other obligations of such other party under this Agreement.

                                       5

<PAGE>
 
Failure on the part of any party to complain of any act or failure to act of any
of the other Parties or to declare the other Parties in default, regardless of
how long such failure continues, shall not constitute a waiver by such Party of
his or its rights hereunder.

     8.  Severability.  If any provision of this Agreement or the application
thereof to any person or circumstance shall be invalid or unenforceable to any
extent, the remainder of this Agreement and the application of such provisions
to other persons or circumstances shall not be affected thereby, and the intent
of this Agreement shall be enforced to the greatest extent permitted by law.

     9.  Binding Agreement.  Subject to the restrictions on transfers and
encumbrances set forth in this Agreement, this Agreement shall inure to the
benefit of and be binding upon the undersigned Parties and their respective
legal representatives, successors and assigns.  Whenever, in this Agreement, a
reference to any Party is made, such reference shall be deemed to include a
reference to the legal representatives, successors and assigns of such Party.

     10.  Captions.  Captions are included solely for convenience of reference
and if there is any conflict between captions and the text of this Agreement,
the text shall control.

     11.  Counterparts.  This Agreement may be executed in multiple
counterparts, each of which shall be deemed an original for all purposes and all
of which when taken together shall constitute a single counterpart instrument.
Executed signature pages to any counterpart instrument may be detached and
affixed to a single counterpart, which single counterpart with multiple executed
signature pages affixed thereto shall constitute the original counterpart
instrument.  All of those counterpart pages shall be read as though one, and
they shall have the same force and effect as if all of the Parties had executed
a single signature page.

     Executed to be effective as of the 25th day of August, 1994.

                             TERMINATION AGREEMENT


       This Termination Agreement (this "Agreement") is made and entered into
effective and dated as of August 25, 1994, by and among AmWest Genpar, Inc., a
Texas corporation ("Genpar"), Apcal, L.P., a Texas limited partnership
("Apcal"), and Mesa Airlines, Inc., a New Mexico corporation ("Mesa").  All
capitalized terms used in this Agreement without definition shall have the
meanings assigned to them in the Limited Partnership Agreement of AmWest
Partners, L.P., dated as of March 16, 1994, as amended (the "Partnership
Agreement").


                                  WITNESSETH:
                                  -----------

       WHEREAS, each of the parties hereto is a Partner in AmWest Partners, L.P.
(the "Partnership"), a Texas limited partnership, formed for the purpose of
investing in Securities of America West Airlines, Inc., including its successor
as reorganized pursuant to Chapter 11 of the United States Bankruptcy Code
("AWA");

       WHEREAS, the Partnership previously has assigned to the Partners the
Partnership's rights and obligations to purchase the Securities pursuant to
notices dated August 23, 1994 and which rights and obligations have been assumed
by the Partners as provided for in such notices;

       WHEREAS, the parties desire to terminate and dissolve the Partnership and
to assign to the Partners
 and certain affiliates of the Partners the Securities
and certain rights and obligations of the Partnership under the Securities
Agreements and certain related agreements as provided herein; and

       WHEREAS, the parties desire to delegate to Genpar the obligations
specified herein requiring Genpar to serve as agent for the Partners for the
mutual benefit of each of them.

       NOW THEREFORE, in consideration of the mutual covenants set forth herein
and for other good and valuable consideration, the adequacy, receipt and
sufficiency of which are hereby acknowledged, the parties hereby agree as
follows:


       SECTION 1.  Dissolution of the Partnership.

       (a)  Pursuant to Section 6.02(c) of the Partnership Agreement, the
Partnership is hereby dissolved.  The execution and delivery of this Agreement
shall constitute the written consent of each Partner to the dissolution of the
Partnership pursuant to said Section 6.02(c).  The rights and obligations of

<PAGE>
 
each Partner relating to dissolution of the Partnership set forth in this
Agreement shall control any contrary provision in the Partnership Agreement.
Genpar is authorized to take all actions necessary or advisable for the
dissolution and termination of the Partnership, and each Limited Partner
constitutes and appoints Genpar, with full power of substitution, as its true
and lawful attorney-in-fact for the limited purpose of dissolution of the
Partnership and the specific obligations contemplated by this Agreement and
empowers and authorizes such attorney, in the name, place and stead of such
Limited Partner, to make, execute, sign, swear to, acknowledge and file in all
necessary or appropriate places all documents necessary or appropriate in the
dissolution of the Partnership.

       (b)  In connection with the dissolution of the Partnership, Genpar shall
prepare and file a final federal income tax return for the 1994 taxable year, as
well as any other reports required to be prepared and filed under Section 4.04
of the Partnership Agreement on behalf of the Partnership and shall exercise on
behalf of the Partnership and the Partners the responsibilities set forth in
Section 2.08 of the Partnership Agreement.  In connection with an audit of the
Partnership by the U.S. Internal Revenue Service, each Partner shall have all
rights under Sections 6221-6233 of the Code to have notice of and participate in
any such audit.  Genpar shall not extend the statute of limitations nor enter
into a settlement agreement with respect to any issue raised in an audit of the
Partnership without the prior written consent of each Partner.  Any direct, out-
of-pocket expense incurred by Genpar in carrying out its responsibilities and
duties under this Section 1(b) shall be allocated and charged to the Partners as
an Expense under Section 3(b) of this Agreement.

       SECTION 2.  Distribution of Securities.  Pursuant to Section 23 of the
Investment Agreement, the Partnership has notified AWA of its assignment of the
right and obligation to purchase Securities thereunder to the Partners or their
Affiliates (as such term is defined in the Investment Agreement, hereinafter
"Affiliates") and other third parties.  Pursuant to prior notice, the
Partnership has assigned to each Partner, and each Partner has assumed, the
following rights and obligations of the Partnership under the Investment
Agreement to purchase Securities:

Genpar and Apcal's rights and obligations to purchase Securities have been
assigned to their Affiliates in accordance with Subscription Agreements, as
amended, entered into between such Affiliates and the Partnership.  Each Partner
(and/or such Affiliates) has been notified by  Genpar of its assignment of
rights and obligations under the Investment Agreement to purchase Securities and
agrees to remit, or cause its Affiliates to remit, cash to AWA, via wire
transfer or otherwise, in consideration of such right in the amount and manner
set forth in the notices received by each Partner (and/or Affiliate).
Notwithstanding anything to the contrary in the Partnership Agreement, each
Partner, or its Affiliates or designees, shall receive its Securities directly
from AWA and will not acquire any Indirect Shares under the Partnership
Agreement.


       SECTION 3.  Expenses.

       (a)  Any Expenses of any Partner not heretofore reimbursed by or
submitted to Genpar under Section 2.05(b) of the Partnership Agreement shall be
submitted to Genpar.  Upon receipt of appropriate documentation, setting forth
in reasonable detail the amount for which reimbursement is sought and the basis
on which the charges were incurred, Genpar shall reimburse such expenses to the
requesting Partner.  Each Partner agrees that it (or, in the case of Apcal, its
constituent partners) shall contribute to Genpar its respective percentage (as
set forth below) of all Expenses and of all similar expenses of Fidelity not
reimbursed by AWA; provided, however, that Genpar shall first seek reimbursement
of all Expenses and all similar expenses of Fidelity from AWA in accordance with
Section 2 of the Third Revised Interim Procedures Agreement dated as of April
21, 1994, by and between AWA and the Partnership (the "Procedures Agreement").
As soon as practicable following the Effective Date, Genpar shall seek
reimbursement from AWA of all Expenses incurred on or after March 1, 1994 by or
on behalf of each Partner and of all similar expenses of Fidelity, without
regard to the limitations set forth in Section 2(a) of the Procedures Agreement.
Genpar shall notify each Partner of any sums due Genpar pursuant to the third
sentence of this Section 3(a) and may set off from any amounts due any Partner
any amount owing from such Partner under this Section 3(a).

behalf of each Partner or the Partnership or for similar expenses sought on
behalf of Fidelity, the amount of Expenses previously paid to or on behalf of
each Partner or the Partnership and of similar expenses previously paid to or on
behalf of Fidelity, and the amount of Expenses owing to or on behalf of each
Partner or the Partnership and of similar expenses previously paid to or on

pocket expenses incurred by such parties with respect to the formation,
operation and dissolution of the Partnership, including, without limitation,

       SECTION 4.  Indemnification and Confidentiality.

       (a)  Rights and Obligations Regarding Indemnification and Liability of
the Partnership Pursuant to the Interim Procedures Agreement.

       (i)  Genpar hereby assigns to each Partner the rights of the Partnership
pursuant to Section 8 of the Procedures Agreement, with respect to elimination
of the Partnership's liability to AWA.

       (ii)  Genpar hereby assigns to each Partner the rights of the Partnership
pursuant to Section 9 of the Procedures Agreement, with respect to any claim
that such Partner may have against AWA as an Investor Indemnified Party (as such
term is defined in the Procedures Agreement, hereinafter, an "Investor
Indemnified Party").

       (iii)  Each Partner (or, in the case of Apcal, its constituent partners)
agrees that to the extent that the Partnership is found to be liable to AWA
under the Investment Agreement or under Section 8 or Section 9 of the Procedures
Agreement as a result solely of any action or omission of a particular Partner
or any of its Affiliates, such Partner (or such Affiliate, as the case may be)
shall indemnify and hold harmless the Partnership and each other Partner (and
its Affiliates, if any) against any and all claims or liabilities of any nature
whatsoever, including reasonable legal fees and other expenses reasonably
incurred, arising out of or in connection with any such liability; provided,
however, that no Partner or Affiliate shall have any obligation to indemnify the
Partnership and each other Partner (and its Affiliates, if any) in an amount,
singly or in the aggregate, in excess of the lesser of (i) the purchase price of
the Securities acquired by such Partner (or its Affiliates) on the Effective
Date (as such term is defined in the Investment Agreement, hereinafter, the
"Effective Date") from AWA or (ii) the Value (as defined without regard to the
definition of "Valuation Date" as set forth in the Partnership Agreement) of any
such Securities held by such Partner (or such Affiliate(s)) at the time that
such Partner (or such Affiliate(s)) becomes obligated to indemnify the
Partnership and each other Partner (and its Affiliates, if any) pursuant to this
Section 4(a)(iii).  In addition, in the event that the Partnership shall be
found in a final judgment by a court of competent jurisdiction to be liable for
any breach of the Investment Agreement or the Procedures Agreement for any
action or omission not solely the responsibility of a particular Partner (or its
Affiliates), each Partner (or its Affiliate(s) which purchased Securities
pursuant to any assignment by a Partner of its right to purchase Securities
under the Investment Agreement) shall contribute to any judgment owed by the
Partnership in the respective percentage set forth opposite its name (or, in the
case of Apcal, its constituent partners' name) in the second table under Section
3(a) hereof; provided, however, that such

                                       5

<PAGE>
 
contribution shall in no event exceed, singly or in the aggregate, the lesser of
(i) the purchase price of the Securities acquired by such Partner (or such
Affiliates) on the Effective Date from AWA or (ii) the Value of any such
Securities held by such Partner (or such Affiliate(s)) at the time that such
Partner (or such Affiliate(s)) becomes obligated to contribute to any such
judgment.

       (b)  Rights and Obligations Regarding Indemnification and Liability of
the Partners.  Each Partner (or, in the case of Apcal, its constituent partners)
shall, to the fullest extent permitted by law, indemnify and hold harmless (in
such capacity, an "Indemnifying Partner") the Partnership and each other
Partner, its directors, officers, shareholders, employees, agents and Affiliates
(each, an "Indemnified Party") from and against any and all claims or
liabilities of any nature whatsoever, including reasonable legal fees and other
expenses reasonably incurred, arising out of, or in connection with the
registration and or sale of all or any portion of the Indemnifying Partner's
Securities if, and only to the extent that, such claims and liabilities arise
out of or in connection with any information provided by such Indemnifying
Partner in writing for use in any registration statement utilized by AWA in
connection with any such registration or sale; provided, however, that no
Partner (or, in the case of Apcal, its constituent partners) shall have any
obligation to indemnify the Partnership and each other Partner (or, in the case
of Apcal, its constituent partners) in an amount, singly or in the aggregate, in
excess of the lesser of (i) the purchase price of the Securities acquired by
such Partner (or its Affiliates) on the Effective Date from AWA or (ii) the
Value of any such Securities held by such Partner (or such Affiliate(s)) at the
time that such Partner (or such Affiliate(s)) becomes obligated to indemnify an
Indemnified Party pursuant to this Section 4(b).  If an Indemnified Party
becomes involved in any capacity in any suit, action, proceeding, or
investigation in connection with any matter which an Indemnifying Partner is
required to provide indemnification pursuant to this Section 4(b), the
Indemnifying Partner periodically shall, upon the request of such Indemnified
Party and receipt of invoices and such supporting documentation as the
Indemnifying Partner reasonably may request, reimburse such Indemnified Party
for its reasonable legal and other expenses (including the cost of any
investigation and preparation) incurred in connection therewith; provided,
however, that prior to any such advancement of expenses (i) such Indemnified
Party shall provide the Indemnifying Partner with an undertaking in form and
substance satisfactory to the Indemnifying Partner to repay promptly the amount
of any such expenses paid to it if it shall ultimately be determined by a court
or arbitrator of competent jurisdiction that such Indemnified Party is not
entitled to be indemnified by the Indemnifying Partner as herein provided in
connection with such suit, action, proceeding, or investigation; and provided
further that the failure for any reason of the Indemnifying Partner to advance
funds to any

                                       6

Indemnified Party shall in no way affect such Indemnified Party's right to
reimbursement of such costs if it is ultimately determined that such Indemnified
Party is entitled to indemnification pursuant to the terms hereof.

       (c)  Genpar hereby assigns to each Partner the rights of the Partnership
pursuant to Section 7 of the Procedures Agreement, with respect to the retention
and protection of Confidential Information (as defined in the Procedures
Agreement, hereafter "Confidential Information").  Each of the Partners hereby
agrees to be bound by the provisions of said Section 7 with respect to any
Confidential Information obtained from any other Partner.

       (d)  Genpar hereby assigns to each Partner the rights of the Partnership
pursuant to Section 21 of the Procedures Agreement, with respect to the sharing
of certain attorney-client privileged communications.  Each of the Partners
hereby agrees to be bound by the provisions of said Section 21 with respect to
any confidential communications received from any other Partner.


       SECTION 5.  Stockholders' Agreement.  Pursuant to Section 6 of the
Investment Agreement, the Partnership, AWA and certain other parties on the
Effective Date shall enter into a Stockholders' Agreement relating to certain
matters concerning the composition and voting of the board of directors of AWA
and the transfer of Securities by certain shareholders of AWA.  The Partnership
hereby assigns to the Partners (and, in the case of Apcal, to its constituent
partners), and such Partners (and, in the case of Apcal, its constituent
Partners) hereby assume the Partnership's rights and obligations under the
Stockholders' Agreement as follows:

       (a)  The Partnership hereby assigns to TPG Partners, L.P. ("TPG"), an
Affiliate of Genpar, the Partnership's right under the Stockholders' Agreement
to designate the AmWest Directors (as such term is defined in the Stockholders'
Agreement, hereinafter, "AmWest Directors") and any replacement of any AmWest
Director; provided, however, that for so long as Mesa owns, directly or
indirectly, securities representing at least 2% of the aggregate voting power of
the outstanding voting equity securities of AWA, TPG shall cause one person
identified by Mesa, who shall be reasonably satisfactory to TPG (the "Mesa
Director"), to be included among the Partnership's or TPG's, as the case may be,
designees to the AWA board of directors.  Mesa agrees that the Mesa Director
shall be a "Citizen of the United States," as such term is defined in accordance
with Section 40102, Title 49, United States Code, as now in effect or as it may
hereafter from time to time be amended.  For so long as Mesa owns, directly or
indirectly, securities representing at least 2% of the aggregate voting power of
the outstanding

                                       7

<PAGE>
 
voting equity securities of AWA and provided that TPG complies with its
obligation to cause one person identified by Mesa to be included among the
Partnership's or TPG's designees to the AWA board of directors, Mesa hereby
agrees to vote its Securities in favor of the Partnership's or TPG's designees,
as the case may be, to the board of directors of AWA.  Each of TPG and Mesa, to
the extent that it shall be entitled hereunder to identify a person to be
designated to the AWA board of directors, agrees to nominate or cause the
nomination of such directors in accordance with the Bylaws of AWA.

       (b)  For so long as the Stockholders' Agreement is in effect, each of the
Partners (and, in the case of Apcal, its constituent partners) agrees to vote
the Securities held and controlled by such Partner (or, in the case of Apcal,
its constituent partners) and to cause any directors of AWA designated by such
Partner (or, in the case of Apcal, its constituent partners) to vote or provide
written consents in favor of each Independent Director (as such term is defined
in the Stockholders' Agreement, hereinafter, an "Independent Director") and to
take any other action necessary to elect such Independent Directors.

       (c)  For so long as the Stockholders' Agreement  or the GPA Voting
Agreement dated as of August 25, 1994 by and between GPA Group plc and the
Partnership is in effect, subject to the conditions set forth in Section 2.1(c)
of the Stockholders' Agreement, each of the Partners agrees (and, in the case of
Apcal, its constituent partners) to vote the Securities held and controlled by
such Partner (or, in the case of Apcal, its constituent partners) and to cause
any directors of AWA designated by such Partner (or, in the case of Apcal, its
constituent partners) to vote or provide written consents in favor of the GPA
Director (as such term is defined in the Stockholders' Agreement, hereinafter,
the "GPA Director") and to take any other action necessary to elect such GPA
Director; provided, however, that the obligation of Mesa to so vote its
Securities in such fashion shall exist only for so long as the Stockholders'
Agreement is in effect.  To the extent that GPA is obligated to vote its
Securities in favor of the Partnership's or TPG's, as the case may be, designees
to the AWA board of directors, TPG shall enforce its rights against GPA equally
on behalf of each TPG designee to the AWA board of directors including, without
limitation, the Mesa Director.

       (d)  For so long as the Stockholders' Agreement is in effect, none of the
Partners nor any of their constituent partners or Affiliates shall sell or
otherwise transfer any common stock of AWA owned by them (other than to an
Affiliate of the transferror) if, after giving effect thereto and to any related
transaction by such person, the total number of shares of Class B Common Stock
of AWA beneficially owned by the transferor will be less than twice the total
number of Class A Common Stock of AWA beneficially owned by the transferor;
provided, however, that nothing contained in this Section 5(d) shall

                                       8

<PAGE>
 
prohibit any owner of common stock of AWA from selling or otherwise
transferring, in a single transaction or related series of transactions, all
shares of common stock of AWA owned by it, subject to the remaining provisions
of the Stockholders' Agreement.

       (e)  For so long as the Stockholders' Agreement is in effect, each of the
Partners (and, in the case of Apcal, its constituent partners) agrees to be
bound by Section 4.2 of the Stockholders' Agreement.  Each of the Partners (and,
in the case of Apcal, its constituent partners) agrees to be bound by Section
4.3 of the Stockholders' Agreement and to cause any Affiliates that may own
Securities to agree to be bound by said Section 4.3.  TPG further agrees that it
shall not transfer or assign all or substantially all of the shares of AWA held
by it in a single transaction or related series of transactions unless the
transferee (including any Affiliate of TPG) agrees in writing to be bound by the
terms of Section 5(a) hereof.

       (f)  For so long as the Stockholders' Agreement is in effect, each of the
Partners (and, in the case of Apcal, its constituent partners) agrees to vote
the Securities held and controlled by such Partner (or, in the case of Apcal,
its constituent partners) in compliance with Section 2.1(h) of the Stockholders'
Agreement.


       SECTION 6.  Registration Rights Agreement.  Pursuant to Section 11 of the
Investment Agreement, the Partnership and AWA shall enter into a registration
rights agreement (the "Rights Agreement") on the Effective Date pursuant to
which the Partnership, its Affiliates (including the Partners) and transferees
and assignees shall have the right to cause AWA to register the Securities
issued or issuable to the Partnership under the Investment Agreement and such
other Persons under the Securities Laws.  The Partnership hereby assigns the
rights of the Partnership under the Rights Agreement to the Partners as follows:

       (a)  Pursuant to Section 11 of the Rights Agreement, the Partnership
hereby assigns to TPG the right and authority to exercise any notice and consent
rights on the part of the Partnership under the Rights Agreement including,
without limitation, the issuance of any Notice of Demand (as such term is
defined in the Rights Agreement, hereinafter, a "Notice of Demand"); provided,
however, that during the Shelf Period (as such term is defined in the Rights
Agreement, hereinafter, the "Shelf Period"), TPG shall provide prior written
notice to each other Partner (or Affiliate of each other Partner known to it) of
any intention of TPG to provide AWA with a Notice of Demand and thereafter shall
not provide AWA with such Notice of Demand unless Mesa shall consent to such
action, which consent shall not be unreasonably withheld;

                                       9

<PAGE>
 
and provided further, that after the Shelf Period, TPG shall provide prior
written notice to each other Partner (or Affiliate of each other Partner known
to it) of any intention of TPG to provide AWA with a Notice of Demand and
thereafter, for so long as Mesa shall be an "affiliate" of AWA within the
meaning of Rule 144 under the U.S. Securities Act of 1933, as amended, shall not
provide AWA with such Notice of Demand unless Mesa shall consent to such action,
which consent shall not be unreasonably withheld.

       (b)  With regard to any notice, demand, request, action or consent
effected by TPG under the Rights Agreement (other than a Notice of Demand) that
TPG effects as the designated transferee Affiliate of the Partnership pursuant
to Section 11 of the Rights Agreement, TPG agrees, if and to the extent that the
consent of or notice to Fidelity or Lehman (as such terms are defined in the
Rights Agreement) is required by the Rights Agreement with regard to such
notice, demand, request, action or consent, then TPG, acting on behalf of the
Partnership, shall provide notice to and consult with Mesa prior to effecting
any such notice, demand, request, action or consent, and shall not effect such
notice, demand, request, action or consent without the consent of Mesa.  Subject
to the limitation contained in the preceding two sentences, if, and to the
extent that, any Partner is entitled to receive notice pursuant to the
provisions of any Securities Agreement, including, without limitation, the GPA
Registration Rights Agreement (as such term is defined in the Rights Agreement),
and an equivalent notice is not required to be provided to each of the other
Partners by virtue of such Securities Agreement, each Partner who receives such
notice shall use its best efforts to provide such notice pursuant to Section
7(a) of this Agreement to each other Partner who holds Securities and does not
receive such equivalent notice .

       (c)  As soon as reasonably practicable following the Effective Date, but
in no event later than ten days following the Effective Date, each of the
Partners shall use its reasonable efforts to prepare jointly and file, as
necessary, a Schedule 13D with the Securities and Exchange Commission, and to
amend such filing as required by Regulation 13D-G under the Securities Act of
1934, as amended.  Each of the Partners (or, in the case of Apcal, its
constituent partners) agrees to provide promptly all necessary information
pertaining to such Partner (or, in the case of Apcal, its constituent partners)
necessary to make such amendments.  Each of the Partners (and, in the case of
Apcal, its constituent partners) of any changes in facts or circumstances that
would require the filing of any such amendments.

       SECTION 7.  Miscellaneous.

       (a)  Notice.  All notices, demands, or requests provided for or permitted
to be given pursuant to this Agreement must be in writing.  All notices,
demands, and requests to be sent to a Partner or any assignee of a Partner
pursuant to this Agreement shall be deemed to have been properly given or served
if:  (i) personally delivered; (ii) deposited prepaid for next day delivery by a
nationally recognized overnight courier service, addressed to such Partner;
(iii) deposited in the United States mail, addressed to such Partner, prepaid
and registered or certified with return receipt requested; or (iv) transmitted
via telecopier or other similar device to the attention of such Partner.  All
notices, demands, and requests so given shall be deemed received:  (i) when
personally delivered; (ii) twenty-four (24) hours after being deposited for next
day delivery with an overnight courier; (iii) forty-eight (48) hours after being
deposited in the United States mail; or (iv) twelve (12) hours after being
telecopied or otherwise transmitted and receipt has been confirmed.  The
Partners and their respective assignees shall have the right from time to time,
and at any time during the term of this Agreement, to change their respective
addresses and each shall have the right to specify as his or its address any
other address within the United States of America by giving to the other parties
at least thirty (30) days' written notice thereof; provided, however, that to be
effective, any such notice must be actually received (as evidenced by a return
receipt).

       (b)  Amendments.  Amendments and supplements to this Agreement shall
require the written consent of each Partner.

       (c)  Governing Law.  Except to the extent that any agreement of the
Partners to vote Securities owned by them may be governed by Delaware law, this
Agreement is made under, and the rights and obligations of the Partners
hereunder shall be interpreted, construed, and enforced in accordance with, the
laws of the State of Texas, without reference to its conflicts of laws
provisions.

       (d)  Rules of Construction.  The general rule of construction for
interpreting a contract, which provides that the provisions of a contract should
be construed against the party preparing the contract, is waived by the parties.
Each party acknowledges that it was represented by separate legal counsel in
this matter who participated in the preparation of this Agreement or it had the
opportunity to retain counsel to participate in the preparation of this
Agreement but chose not to do so.

       (e)  Gender, Etc.  Unless the context clearly indicates otherwise, the
singular shall include the plural and vice versa.  Whenever the masculine,
feminine, or neuter gender is used inappropriately in this Agreement, this
Agreement shall be read as if the appropriate gender was used.

       (f)  Captions.  Captions are included solely for convenience of reference
and if there is any conflict between captions and the text of this Agreement,
the text shall control.  Unless otherwise specifically stated, references to
Sections refer to the Sections of this Agreement.

       (g)  Entire Agreement.  This Agreement contains the entire agreement
among the parties relative to the matters contained in this Agreement.

       (h)  Waiver.  No consent or waiver, express or implied, by any Partner to
or for any breach or default by any other Partner in the performance by such
other Partner of its obligations under this Agreement shall be deemed or
construed to be a consent or waiver to or of any other breach or default in the
performance by such other Partner of the same or any other obligations of such
other Partner under this Agreement.  Failure on the part of any Partner to
complain of any act or failure to act of any of the other Partners or to declare
any of the other Partners in default, regardless of how long such failure
continues, shall not constitute a waiver by such Partner of its rights
hereunder.

       (i)  Severability.  If any provision of this Agreement or the application
thereof to any person or circumstance shall be invalid or unenforceable to any
extent, the remainder of this Agreement and the application of such provisions
to other persons or circumstances shall not be affected thereby, and the intent
of this Agreement shall be enforced to the greatest extent permitted by law.

       (j)  Binding Agreement.  Subject to the restrictions on transfers and
encumbrances set forth in this Agreement, this Agreement shall inure to the
benefit of and be binding upon the undersigned Partners and their respective
legal representatives, successors, and assigns.  This Agreement shall be binding
upon, and enforceable by the other parties hereto (including, without
limitation, by Mesa) against, TPG or Continental only to the extent that (i) as
of the date of this Agreement, TPG or Continental have any obligations to the
Partnership including, without limitation, pursuant to Subscription Agreements
entered into by the Partnership with TPG and Continental, or (ii) TPG or
Continental has specifically assumed obligations to the Partnership or to Mesa
pursuant to this Agreement.

       (k)  Counterparts.  This Agreement may be executed in multiple
counterparts, each of which shall be deemed an original for all purposes and all
of which when taken together shall constitute a single counterpart instrument.
Executed signature pages to any counterpart instrument may be detached and
affixed to a single counterpart, which single counterpart with multiple executed
signature pages affixed thereto constitutes the original counterpart instrument.
All of these counterpart pages shall be read as though one and they shall have
the same force and effect as if all of the parties had executed a single
signature page.

Attention:  William A. Franke and Martin J. Whalen

            RE:  AmWest Partners, L.P.

Dear Sirs:

          Reference is made to Section 23 of the Third Revised Investment
Agreement dated April 21, 1994 by and between America West Airlines, Inc. and

          2.1  Shelf Registration Statements.

          (a)  Filing of Initial Shelf Registration Statement.  If, as of the
Initial Effective Date, (i) the effectiveness of the shelf registration
statement covering all of the Registrable Equity Securities and the Initial
Registrable Debt Securities (the "Initial Shelf Registration Statement") has
been suspended or the Initial Shelf Registration Statement is otherwise not
effective or (ii) the securities covered under the Initial Shelf Registration
Statement shall not qualify under all blue sky or other securities laws, the
Company shall use Commercially Reasonable Efforts to cause such Initial Shelf
Registration Statement to be effective as soon as practicable and to qualify

practicable.

          (b)  Filing of Secondary Shelf Registration Statement.  If, as of the
Secondary Effective Date, (i) the effectiveness of the shelf registration
statement covering all of the Secondary Registrable Debt Securities (the

Reasonable Efforts to cause such Secondary Shelf Registration Statement to be
effective as soon as practicable and to qualify such securities under all blue

          (c)  Continuous Effectiveness of Shelf Registration Statements.  Once
a Shelf Registration Statement is effective pursuant to Section 2.1(a) or
2.1(b), the Company shall use Commercially Reasonable Efforts to cause such
Shelf Registration Statement to remain continuously effective until the earlier
of (i) the third (3rd) anniversary of (A) in the case of the Initial Shelf
Registration Statement, the Initial Effective Date or (B) in the case of the
Secondary Shelf Registration Statement, the Secondary Effective Date and (ii) in
either case, the date on which all of the Registrable Securities covered by such
Shelf Registration Statement have been sold, but in no event prior to the
expiration of the applicable period referred to in Section 4(3) of the
Securities Act and Rule 174 thereunder (such period with respect to the Initial
Shelf Registration Statement or the Secondary Shelf Registration being defined
as the "Shelf Period" with respect to such Shelf Registration Statement);
provided, however, that with respect to each such Shelf Registration Statement
(x) the Company may (no more than twice during any twelve (12) month period and
for a period not to exceed forty-five (45) days on any one occasion, and not in
any event to exceed sixty (60) days in the aggregate) suspend use of such Shelf
Registration Statement at any time if the continued effectiveness thereof would
require the Company to disclose a material financing, acquisition or other
corporate transaction, which disclosure the Board of Directors of the Company
shall have determined in good faith is not in the best interests of the Company
and its stockholders and (y) the Company may suspend use of each such Shelf
Registration Statement during any period (not to exceed forty-five (45) days in
the aggregate) if each of the Company and the Requisite Holders of each of the
Registrable Equity Securities, if any, and the Registrable Debt Securities
covered by such Shelf Registration Statement consents in writing to such
suspension for such period, provided, further, that Investor and any of its
Affiliates (other than Mesa) shall not participate in any such consent and that
any Registrable Equity

                                       9

<PAGE>
 
Securities or Registrable Debt Securities held by such parties shall not be
taken into account for the purpose of such consent.

          (d) Underwritten Offering.  If the Requisite Holders of each of the
Registrable Equity Securities and the Registrable Debt Securities covered by the
Initial Shelf Registration Statement and the Secondary Shelf Registration
Statement, if any, acting together, so elect, the offering of Registrable
Securities pursuant to such Shelf Registration Statements shall be in the form
of an underwritten offering, with such book-running managing underwriter or
underwriters as they shall jointly select with the approval of the Company, such
approval not to be unreasonably withheld.

          2.2  Demand Registration.

          (a)  Registration on Request.  Except as provided in subsection (b)
below,

               (i)  at any time after the Shelf Period applicable to the Initial
          Shelf Registration Statement, Investor may provide the Company with a
          Notice of Demand (with a copy to GPA); and

              (ii)  if at any time during the Shelf Period the Initial Shelf
          Registration Statement is not effective during a continuous period of
          ten (10) days for any reason (other than under the circumstances and
          during the periods permitted by the first proviso in Section 2.1(c)),
          each of Investor and Fidelity may, at any time prior to the renewed
          effectiveness of such Initial Shelf Registration Statement or any
          replacement Shelf Registration Statement for such Initial Shelf
          Registration Statement, provide the Company with a Notice of Demand
          (with a copy to GPA) (which, in the case of Investor, shall be in
          addition to its right to provide the Company with a Notice of Demand
          pursuant to clause (i) above).

Upon receipt of a Notice of Demand, the Company shall use Commercially
Reasonable Efforts to effect at the earliest practicable date the registration
under the Securities Act of the Registrable Securities that the Company has been
so requested to register (whether pursuant to the Notice of Demand or pursuant
to notice provided under Section 2.2(d)), for disposition in accordance with the
intended method or methods of disposition specified in the Notice of Demand or
such other notice.

          (b)  Limitations on Demand Registration.  The Company shall not be
obligated to take any action to effect any registration pursuant to this Section
2.2:  (i) after the Company has, in accordance with the provisions of Section
2.5(c),

                                      10

<PAGE>
 
effected (A) one (1) registration of Registrable Securities with respect to a
registration requested pursuant to Section 2.2(a)(i) and (B) two (2)
registrations of Registrable Securities with respect to a registration requested
pursuant to Section 2.2(a)(ii); and (ii) in any period during which the Company
has suspended registration pursuant to the first proviso in Section 2.1(c).

          (c)  GPA Demand Registration.  If GPA exercises its right to a demand
registration (the "GPA Demand") pursuant to Section 2.2 of the GPA Registration
Rights Agreement, then the Company shall provide Investor and each of its
Affiliates which have been designated by Investor by notice to the Company to be
given notice of the GPA Demand (pursuant to the proviso to Section 11 or
otherwise), with a copy of such demand within five (5) Business Days of its
receipt thereof, and Investor may (but shall not be obligated to) provide the
Company with a Notice of Demand pursuant to Section 2.2(a) within twenty-one
(21) days of Investor's receipt of a copy of the GPA Demand and thereby void the
GPA Demand and obligate the Company to effect a registration of Registrable
Securities pursuant to Section 2.2(a)

          (d)  Notice to certain non-Requesting Holders.  Upon receipt of any
Notice of Demand from a Requesting Holder or any GPA Demand, the Company will
give prompt (but in any event within fifteen (15) days after such receipt)
notice to all Holders of Registrable Securities of such Notice of Demand or GPA
Demand and of such Holders' rights under this Section 2.2.  Upon the request of
any such Holder made within fifteen (15) days after the receipt by such Holder
of any such notice (which request shall specify the Registrable Securities
intended to be disposed of by such Holder and the intended method or methods of
disposition thereof), the Company will use Commercially Reasonable Efforts to
effect the registration of all Registrable Securities which the Company has been
so requested to register pursuant to the Notice of Demand or GPA Demand.  The
participation of Investor, any Fidelity Fund, Lehman or any of their respective
Affiliates or transferees, direct or indirect, in a GPA Demand pursuant to this
Section 2.2(d) shall (i) be subject to the provisions of Section 2.3(a) and
2.3(c) hereof and (ii) with respect to Investor, or Fidelity shall not be
considered a Notice of Demand pursuant to Section 2.2(a) and shall have no
effect on such parties' right to provide the Company with a Notice of Demand
pursuant thereto.

          (e)  Priority in Demand Registrations.  If (i) a registration pursuant
to this Section 2.2 involves an underwritten offering of the securities being
registered 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 Requesting Holder by letter of its
belief that

                                      11

<PAGE>
 
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 each of
Investor, any Fidelity Fund, Lehman or 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; second, such Registrable Securities
requested to be included in such registration by the direct or indirect
transferees of Registrable Securities held by Investor, any Fidelity Fund,
Lehman, or 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 securities requested to be included in such registration by
GPA or any of its Affiliates, pursuant to the GPA Registration Rights Agreement,
pro rata on the basis of the amount of such securities so proposed to be sold
and so included by such parties; fourth, such securities requested to be
included in such registration by the direct or indirect transferees of
securities held by GPA or any of its Affiliates, pursuant to the GPA
Registration Rights Agreement, pro rata on the basis of the amount of such
securities so proposed to be sold and so included by such parties, and fifth,
such Registrable 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 parties.

          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, with
the exception of a registration pursuant to a GPA Demand) 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 Efforts to effect the

                                      12

<PAGE>
 
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 Registrable Equity Securities in connection with such registration (but not
from its obligation to pay all Registration Expenses in connection therewith as
provided in Section 2.5(b)), without prejudice, however, to 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 (except for any right to demand
registration which may be exercised pursuant to the last clause of subsection
(i) of the preceding sentence) 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 (other than a registration made pursuant to a GPA
Demand) 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,
Lehman, 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

                                      13

<PAGE>
 
be included in such registration by the direct or indirect transferees of
Registrable Equity Securities held by Investor, Lehman, 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; fourth, such securities requested to be included in such registration
by GPA or any of its 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; fifth, such securities requested to be included in such registration by
the direct and indirect transferees of such securities held by GPA or any of its
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; and sixth, all other
securities of the Company requested to be included in such registration pro rata
on the basis of the amount of such securities so proposed to be sold and so
requested to be included.

          (c)  Priority in Piggyback Registrations Pursuant to a GPA Demand.  If
(i) a registration pursuant to this Section 2.3 is made pursuant to a GPA Demand
and involves an underwritten offering of the securities being registered 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, such securities requested to be included in such registration by GPA or
any of its 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; second,
such securities requested to be included in such registration by the direct and
indirect transferees of such securities held by GPA or any of its 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 Investor, Lehman,
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; fourth, such Registrable Equity Securities requested
to be included in such registration by the direct or indirect transferees of
Registrable Equity Securities held by Investor, Lehman, 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; and fifth, all other securities

                                      14

<PAGE>
 
of the Company requested to be included in such registration pro rata on the
basis of the amount of such securities so proposed to be sold and so requested
to be included.

          2.4  Trust Indenture Act Qualification; Rating.  At or prior to the
date the SEC declares the Initial Shelf Registration Statement to be effective,
the Company shall qualify the Indenture under the Trust Indenture Act, and shall
use Commercially Reasonable Efforts to effect such registration to permit the
sale of the Notes thereunder in accordance with the intended method or methods
of disposition thereof.  If notified by a nationally recognized rating agency
that the Notes are being rated, the Company shall cooperate in providing
information and making a presentation to such agency in connection therewith.

          2.5  Registration Terms and Procedures.

          (a)  Registration Statement Form.  Registrations under Section 2.2
shall be on such appropriate registration forms of the SEC (i) as shall be
acceptable to the Requesting Holder (such acceptance not to be unreasonably
withheld) and (ii) as shall permit the disposition of such Registrable
Securities in accordance with the intended method or methods of disposition.
The Company agrees to include in any such registration statement all information
that any Participating Holder shall reasonably request (to the extent such
information relates to such Participating Holder).

          (b)  Registration Expenses.  Subject to Section 2.5(f), the Company
will pay all Registration Expenses incurred in connection with a registration to
be effected (whether or not effected or deemed effected pursuant to subsection
(c) below) pursuant to Sections 2.1, 2.2 or 2.3.

          (c)  Effectiveness of Demand Registration.  A registration will not be
deemed to have been effected under Section 2.2 unless the registration statement
with respect thereto has been declared effective by the SEC and, subject to the
first proviso in Section 2.1(c) hereof and to Section 2.5(g)(vii) hereof,
remains effective for the earlier of six (6) months (subject to extension as
contemplated by the last sentence of Section 2.5(h)(ii)) or the distribution of
the securities covered by such registration statement; provided, however, that
if (i) after such registration statement has been declared effective, the
marketing of Registrable Securities offered pursuant to such registration
statement is materially disrupted or adversely affected as a result of any stop
order, injunction or other order or requirement of the SEC or any other
governmental agency or court (for reasons other than a misrepresentation or
omission by the Requesting Holder or any Participating Holder) or (ii) the
conditions to closing specified in the purchase agreement or underwriting
agreement entered into

                                      15

<PAGE>
 
in connection with such registration have not been satisfied (for reasons other
than a wrongful or bad faith act, omission or misrepresentation by the
Requesting Holder or any Participating Holder), such registration statement will
be deemed not to have become effective.  If a registration pursuant to Section
2.2 is deemed not to have been effected hereunder, then the Company shall
continue to be obligated to effect a registration pursuant to such Section.

          (d)  Selection of Underwriter.  If, in connection with a registration
effected pursuant to Section 2.2, the Requesting Holder so elects, the offering
of Registrable Securities pursuant to such Section shall be in the form of an
underwritten offering.  If the Requesting Holder so elects, it shall select one
or more nationally recognized firms of investment bankers to act as the book-
running managing underwriter or underwriters in connection with such offering,
provided that such selection shall be subject to the consent of the Company,
which consent shall not be unreasonably withheld.

          (e)  Registration of Securities.  Participating Holders may seek to
register different types of Registrable Securities and/or different classes of
the same type of Registrable Securities simultaneously and the Company shall use
its, and in the case of an underwritten offering, shall cause the managing
underwriter or underwriters to use Commercially Reasonable Efforts to effect
such registration and sale in accordance with the intended method or methods of
disposition specified by such Holders.

          (f)  Withdrawal.  Any Holder participating in a registration pursuant
to this Agreement shall be permitted to withdraw all or part of its Registrable
Securities from such registration at any time prior to the effective date of the
registration statement covering such securities; 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 fifty percent (50)% of the reasonable out-of-
pocket fees and expenses paid by the Company hereunder or (ii) the Requesting
Holder elects to terminate such registration due to the occurrence of a Material
Adverse Change; provided, however, that during the term of this Agreement only
one such withdrawal shall be permitted pursuant to the preceding proviso.

          (g)  Registration Procedures.  In connection with the Company's
obligations to register Registrable Securities pursuant to this Agreement, the
Company will use Commercially Reasonable Efforts to effect such registration so
as to permit the sale of any Registrable Securities included in such
registration in

                                      16

<PAGE>
 
accordance with the intended method or methods of distribution thereof, and
pursuant thereto the Company will as expeditiously as possible:

             (i)  prepare and (as soon thereafter as practicable) file with the
     SEC the requisite registration statement containing all information
     required thereby to effect such registration and thereafter use
     Commercially Reasonable Efforts to cause such registration statement to
     become and remain effective in accordance with the terms of this Agreement,
                                                                                
     provided that as far in advance as practicable before filing such
     registration statement or any amendment, supplement or exhibit thereto
     (but, with respect to the filing of such registration statement, in no
     event later than seven (7) 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 information relating to
     such Holder or the plan of distribution of the Registrable Securities prior
     to filing any such registration statement, amendment, supplement or
     exhibit;

             (ii)  prepare and file with the SEC such amendments and supplements
     to such registration statement and the prospectus used in connection
     therewith (A) as reasonably requested by any Participating Holder to which
     such registration statement relates (but only to the extent such request
     relates to information with respect to such Holder) and (B) as may be
     necessary to keep such registration statement effective for the applicable
     Shelf Period in the case of a Shelf Registration Statement or six (6)
     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 Securities Act with respect to the sale or other disposition of all
     securities covered by such registration statement during such period in
     accordance with the intended method or methods of disposition by the seller
     or sellers thereof set forth in such registration statement;

             (iii)  furnish to each Holder covered by, and each underwriter or
     agent participating in the disposition of securities under, such
     registration statement such number of conformed copies of such registration
     statement and of each

                                      17

     and documents incorporated by reference, which exhibits and documents shall
     be furnished to any such Person upon request), such number of copies of the
     prospectus (which in the case of Shelf Registration Statements, shall be
     substantially the same prospectus for both such Shelf Registration
     Statements) 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 Efforts to register or qualify
     all Registrable Securities and other securities covered by such
     registration statement under (A) with respect to the Shelf Registration
     Statements, all blue sky and other securities laws and (B) with respect to
     a registration effected pursuant to Section 2.2, all applicable blue sky
     and other securities laws, and to keep such registration or qualification
     in effect for so long as such registration statement remains in effect, and
     take any other action which may be reasonably necessary or advisable to

     in any jurisdiction 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 jurisdiction or (c) consent to general service of process in
     any jurisdiction;

             (v)  use Commercially Reasonable 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 Registrable Equity Securities or
     Registrable Debt Securities covered by such registration statement a signed
     counterpart, addressed to such Holder (and underwriter or agent, if any)
     of:

               (A)  an opinion of counsel to the Company, dated the effective
          date of such registration statement (and, if such registration
          includes an underwritten public

                                      18

          offering, dated the date of the closing under the underwriting
          agreement), and

               (B)  unless otherwise precluded under applicable accounting
          rules, 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 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 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

                                      19

<PAGE>
 
     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 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 System of NASDAQ if the Registrable
     Equity Securities so qualify; in each case subject to the applicable
     listing requirements of the respective securities exchange or NASDAQ;

             (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 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
     Efforts to cause such order to be lifted as promptly as practicable;

             (xiii)  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

                                      20

<PAGE>
 
          post-effective amendment thereto, when the same has become effective;

               (B) of any written comments from the SEC with respect to any
          filing referred to in clause (A) and of any written request by the SEC
          for amendments or supplements to such registration statement or
          prospectus;

               (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

               (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 or the agreement pursuant to which the Secondary Registrable Debt
     Securities are acquired on an initial issue by any Fidelity Fund or Lehman)
     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;

                                      21

<PAGE>
 
             (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); and

             (xix)  in connection with an underwritten offering, participate, to
     the extent reasonably requested by the Requisite Holders of the securities
     included in the offering or the managing underwriter for the offering, in
     customary efforts to sell the securities under the offering.

          (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, Lehman,
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 that such reference be in a form reasonably satisfactory to
such Holder or 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) (the period from the date on which such Holder receives a Suspension
Notice to the date on which such Holder receives copies of the supplemental or
amended prospectus being herein called the "Suspension Period").  The Company
shall take such actions as are necessary to end the Suspension Period as
promptly as practicable.  In the event the Company shall give any such notice,
the periods referred to in Section 2.5(c) and 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 (A) the Company
and (B) to the Requisite Holders of each of the Registrable Equity Securities
and the Registrable Debt Securities included in such offering, acting together,
(provided that the Company shall not be required to have in effect more than one
underwriting agreement at any one time in connection with the Shelf Registration
Statements) and (ii) to contain such representations and warranties by the
Company and such Holders 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, Lehman 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.

          (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
Sections 2.3(b) and 2.3(c), 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 Company and the Requisite Holders of each of the Registrable Equity
Securities included in such offering, 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.

                                      23

<PAGE>
 
          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 of securities provided for as described herein
(including, without limitation, under a Shelf Registration Statement or any
replacement Shelf Registration Statement), its directors, officers,
shareholders, employees, investment advisers, agents and Affiliates, either
direct or indirect (and each such Affiliate's 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, to the extent that 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

                                      24

<PAGE>
 
reliance upon and in conformity with written information furnished to the
Company 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 (in accordance with the notice
     provisions contained in Section 10 for Persons who are parties to this
     Agreement) with a sufficient number of copies of the same for delivery 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.  Each Holder participating in a
Shelf Registration Statement filed pursuant to Section 2.1 agrees to (and the
Company may require, as a condition to including any Registrable Securities in
any registration statement filed pursuant to Sections 2.2 or 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

                                      25

<PAGE>
 
securities included in any such offering regarding its agreement to) indemnify
and hold harmless and reimburse (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 based upon any untrue statement or alleged
untrue statement of a material fact contained in any such Shelf Registration
Statement or other registration statement pursuant to which securities of such
Holder are 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 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

                                      26

<PAGE>
 
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 exists 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 one additional counsel or firm of counsel for such indemnified
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 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

                                      27

<PAGE>
 
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, (i) as of the Initial Effective Date, the Initial Shelf
Registration Statement has been suspended or is not otherwise effective or (ii)

exercise of the Warrant), for each week specified in subsection (g) below.

          (c)  If the suspension or ineffectiveness referred to in clause (a)

any Warrant, $.90 per 1,000 shares based on the number of shares issuable upon
exercise of the Warrant), for each week specified in subsection (g) below.

          (d)  If a stop order is imposed or if for any other reason the
effectiveness of a Shelf Registration Statement is suspended during the Shelf
Period applicable to such Shelf Registration Statement, the Company shall pay
liquidated damages to each Holder covered or to be covered by such Shelf
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, $.40 per
1,000 shares (or in the case of any Warrant, $.40 per 1,000 shares 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 a 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 effectiveness
of such Shelf Registration Statement was otherwise suspended, the daily
liquidated damages set forth in clause (d) above shall increase to 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, $.65 per 1,000 shares (or in the case of
any Warrant, $.65 per 1,000 shares 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 a 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 was imposed or
the effectiveness of such Shelf Registration Statement was otherwise suspended,
the daily liquidated damages set forth in clause (d) above shall increase to an
amount equal to (i) in the case of Registrable Debt Securities, $.20 per $1,000
outstanding principal amount of such Registrable Debt Securities and (ii) in the
case of Registrable Equity Securities, $.90 per 1,000 shares (or in the case of
any Warrant, $.90 per 1,000 shares based on the number of shares issuable upon
exercise of the Warrant), for each week specified in subsection (g) below.

          (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 on the earlier of the date
after the SEC reinstates the effectiveness of the relevant Shelf Registration
Statement or otherwise declares such 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.
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 in immediately available funds by wire transfer
to each Holder of at least ten percent (10%) of Registrable Equity Securities
(but not less than an aggregate of 2,000,000 shares of Class A Common, Class B
Common and shares issuable upon exercise of Warrants) or at least ten percent
(10%) of the aggregate principal amount of Registrable Debt Securities (but not
less than $10 Million of aggregate principal amount of Registrable Debt
Securities) entitled to receive such liquidated damages to the accounts
designated by such Holders, and all other Holders entitled to receive such
funds, shall be paid by check mailed to such other Holders at the address shown
in the records of the Company for such Holders; provided that for purposes of
this Section 2.9(g), all Fidelity Funds shall be considered a single Holder.

          (h)  Notwithstanding any of the provisions of this Section 2.9, no
liquidated damages shall be payable (i) during any period of time that (A) a
Shelf Registration Statement or any replacement Shelf Registration Statement is
suspended by the Company pursuant to the first proviso in Section 2.1(c), or (B)
the Company is precluded from using or qualifying a Shelf Registration Statement
as a result of a change to the rules or regulations of the SEC applicable
thereto with which the Company is unable to comply after exercising Commercially
Reasonable Efforts to so comply; and (ii) to any party, if, as a result of such
party's acts or omissions, the Company is precluded from using or qualifying a
Shelf Registration Statement.

                                      30

<PAGE>
 
          (i)  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 a Shelf Registration
Statement by reason of the failure of such Shelf Registration Statement 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 as Investor, Lehman and/or any Fidelity Fund may reasonably request, all
to the extent required from time to time to enable Investor, Lehman and/or such
Fidelity Fund to sell 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 similar rule or regulation hereafter adopted by the
SEC.  Upon the request of Investor, Lehman and/or any Fidelity Fund, the Company
will deliver to Investor, Lehman and/or such Fidelity Fund a written statement
as to whether it has complied with such requirements and will, at its expense,
forthwith upon the request of Investor, Lehman and/or such Fidelity Fund,
deliver to Investor, Lehman and/or such Fidelity Fund a certificate, signed by
the Company's principal financial officer, stating (A) the Company's name,
address and telephone number (including area code), (B) the Company's Internal
Revenue Service identification number, (C) the Company's SEC file number, (D)
the amount of shares of each class of capital stock outstanding as shown by the
most recent report or statement published by the Company, and (E) whether the
Company has filed the reports required to be filed under the Exchange Act for a
period of at least ninety (90) days prior to the date of such certificate and in
addition has filed the most recent annual report required to be filed
thereunder.

          (b)  If at any time the Company is not required to file reports in
compliance with either Section 13 or Section 15(d) of the Exchange Act, the
Company at its expense will, forthwith upon the request of Investor, Lehman
and/or 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 (d)(4)(ii)
of Rule 144A).

          4.  Term.  This Agreement shall enter into force on the date hereof
and shall continue in full force and effect, subject to Section 18 hereof, until
the eighth (8th) anniversary of the date hereof.

                                      31

<PAGE>
 
          5.  Amendments and Waivers.  This Agreement may be amended,
supplemented or modified at any time; provided that each of (i) the Requisite
Holders of each of the Registrable Equity Securities and the Registrable Debt
Securities then outstanding and (ii) the Company has provided its written
consent to such amendment, supplement or modification; provided, however, that
no such amendment, supplement or modification which would prejudice the rights
expressly granted to Fidelity or any Fidelity Fund as a named party hereto shall
be effective without the written consent of Fidelity or such Fidelity Fund, as
the case may be; and provided further, that no such amendment, supplement or
modification which would prejudice the rights expressly granted to Lehman as a
named party hereto shall be effective without the written consent of Lehman.
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, Lehman, any Fidelity Fund, (ii) any transferee, direct or
indirect, of any of the Registrable Securities held by Investor, Lehman, any
Fidelity Fund or any of their respective Affiliates, or (iii) any other Person
entitled to notice of the registration of Registrable Securities under Sections
2.2(d) 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

                                      32

<PAGE>
 
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.

          10.  Notices.  All notices, requests and other communications
hereunder must be in writing and will be deemed to have been duly given only if

receive notice, requests or other communications hereunder, such notices,
requests and other communications shall be sent to the addresses and telecopy
numbers provided to the Company and the other parties hereto by notice as herein
provided and referencing this Agreement.  All such notices, requests and other
communications will (i) if delivered personally to the address as provided in

transmission to the facsimile number as provided in this Section 10, be deemed
given upon receipt, and (iii) if delivered by courier service or  by mail in the
manner described above to the address as provided in this Section 10, be deemed
given upon receipt (in each case regardless of whether such notice, request or

time may change its address, facsimile number or other information for the
purpose of notices to that Person by giving notice in accordance with this
Section 10 specifying such change to each of the other parties executing this

          11.  Assignment.  This Agreement shall be binding upon and inure to
the benefit of and be enforceable by the parties and their respective Successors
(including, in the case of the Company, the Company as reorganized pursuant to
the Plan) and permitted assigns.  In addition, each of Investor, Lehman, any
Fidelity Fund, and each of their respective Affiliates may assign any of its
rights hereunder (in whole or in part) to one or more Affiliates or to one or
more direct or indirect transferees of its Registrable Securities, provided,
however, that any such assignment by Investor to one or more of its Affiliates
which results in the liquidation of its entire interest in the Registrable
Securities, either upon dissolution or otherwise, shall include a designation of
the transferee Affiliate or Affiliates who shall thereafter have the right and
authority to

                                      35

<PAGE>
 
exercise any notice or consent rights on the part of Investor set forth in this
Agreement, and each other holder of Registrable Securities by means of an
assignment by Investor shall be bound by the actions taken by such designated
Affiliate(s), and provided further that any assignee which accepts the benefits
of this Agreement shall be deemed to have accepted and be bound by all
obligations on the part of the assignor hereunder.  No such assignment shall be
binding upon or obligate the Company to any such assignee unless and until (A)
the Company shall have received notice of such assignment as herein provided,
which notice shall (i) reference this Agreement and (ii) set forth the name and
address of any assignee for the purpose of any notices hereunder or (B) such
assignee can establish its beneficial or record ownership of any Registrable
Securities and shall have provided the Company with the information called for
by clause (A)(ii) of this Section 11.

          12.  Descriptive Headings.  The descriptive headings of the several
sections and paragraphs of this Agreement are inserted for convenience of
reference only and do not define or limit the provisions hereof or otherwise
affect the meaning hereof.

          13.  Specific Performance.  Except with respect to the matters set
forth 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; and (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.

          14.  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REFERENCE TO THE
CONFLICTS OF LAW PRINCIPLES THEREOF.

          15.  Registration Rights to Others.  Except for registration rights
granted by the Company to GPA under that certain Registration Rights Agreement
of even date herewith (the "GPA Registration Rights Agreement"), the Company
shall not provide to any other holder of its securities rights with respect to
the registration of such securities under the Securities Act without the prior
written consent of the Requisite Holders of each of the Registrable Equity
Securities and the Registrable Debt Securities then outstanding, which consent
shall not be unreasonably withheld; provided, however, that the foregoing
restriction shall not be applicable (i) to the grant by the Company of
"piggyback" registration rights which are subordinate in priority to the rights
of Holders of Registrable Securities pursuant to Sections 2.2(d) and 2.3(b), and
(ii) to any grant of

                                      36

<PAGE>
 
any demand registration rights by the Company after exercise or termination of
all demand registration rights set forth in Section 2.2, provided, however, that
in regard to any such grant of demand registration rights each of Investor, each
Fidelity Fund, Lehman and each of their respective Affiliates shall have the
right during the term of this Agreement to subscribe to or otherwise participate
in such rights on equal terms, and on a pro rata basis, with the parties granted
such rights.  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 or to
be issued by it.

          16.  Attorneys' Fees.  In any action or proceeding brought to enforce
any provision of this Agreement or where any provision hereof is validly
asserted as a defense, the successful party shall, to the extent permitted by
applicable law, be entitled to recover reasonable attorneys' fees in addition to
any other available remedy.

          17.  Limitation of Liability.  Each party to this Agreement
acknowledges and agrees that (i) this Agreement is not executed on behalf of or
binding upon any of the trustees, officers, directors, partners or shareholders
of any Fidelity Fund individually, but is binding only upon the assets and
property of each Fidelity Fund and (ii) the obligations of each Fidelity Fund
hereunder are several and not joint.  With respect to the obligations of any
Fidelity Fund arising out of this Agreement, each party to this Agreement shall
look for payment or satisfaction of any claim solely to the assets and property
of such Fidelity Fund.

          18.  Termination of Certain Rights.  The rights and obligations
hereunder of each of Investor, Lehman and each Fidelity Fund shall terminate
with respect to such party at such time when neither it nor any of its
respective Affiliates holds Registrable Securities, provided that the provisions
of Section 2.8 hereof, the rights of any party hereto with respect to the breach
of any provision hereof, and any obligation accrued as of the date of
termination (including any obligation accrued under Section 2.9 hereof) shall
survive termination of this Agreement.

          19.  No Inconsistent Agreements.  The Company will not hereafter enter
into, modify, amend or waive any agreement with respect to its securities if
such agreement, modification, amendment or waiver would conflict with the rights
granted pursuant to this Agreement to the Holders of Registrable Securities.
Without limiting the generality of the foregoing and subject to Section 18
hereof, the Company will not amend, modify or waive, or permit the amendment,
modification or waiver of Sections 2.1, 2.2 or 2.3 of the GPA Registration
Rights Agreement without the prior written consent of the Requisite Holders of

                                      37

<PAGE>
 
each of the Registrable Equity Securities and the Registrable Debt Securities
then outstanding, provided, however, that Investor and any of its Affiliates
(other than Mesa) shall not participate in any such consent and that any
Registrable Equity Securities or Registrable Debt Securities held by such
parties shall not be taken into account for the purpose of such consent.

          20.  Requisite Holders.  Each of the parties hereto agrees that the
Company may, in connection with the taking of any action permitted to be taken
hereunder with the consent or approval of the Requisite Holders of the
Registrable Equity Securities or Registrable Debt Securities, rely in good faith
on a certificate from any such holder or holders stating that it holds or is
acting on behalf of a majority in interest of the Registrable Equity Securities
or a majority in principal amount of the Registrable Debt Securities, as the
case may be.

          21.  Counterparts.  This Agreement may be executed simultaneously in
any number of counterparts, each of which shall be deemed an original, but all
of which shall together constitute one and the same instrument.

          22.  Repurchase Arrangement.  Notwithstanding anything contained in
this Agreement to the contrary, the parties hereto agree and acknowledge that
all rights of Fidelity Copernicus Fund, L.P. ("Copernicus") under this Agreement
in respect of Registrable Debt Securities held by Copernicus shall inure to the
benefit of and be enforceable by Copernicus, Lehman Government Securities Inc.
or any other transferee (including any counterparty) of such Registrable Debt
Securities, in each case as contemplated by the repurchase arrangement described
under "Plan of Distribution" as set forth in the Company's S-1 Registration
Statement filed with the SEC on June 26, 1994, as amended, provided that the
Company shall have no obligations under this Agreement with respect to any such
Person other than Copernicus unless and until it shall have been provided the
notice of assignment or information regarding ownership as set forth in Section
11 of this Agreement.

<PAGE>
 
               (i) at any time after the Shelf Period, GPA may (so long as it or
          any of its Affiliates holds Registrable Securities to be included in
          the registration) provide the Company with a Notice of Demand (with a
          copy to AmWest); and

               (ii) if at any time during the Shelf Period the Shelf
          Registration Statement is not effective during a continuous period of
          10 days for any reason (other than under the circumstances and during
          the periods permitted by the proviso to Section 2.1(b)), GPA may, at
          any time prior to renewed effectiveness of such Shelf Registration
          Statement, provide the Company with a Notice of Demand (which shall be
          in addition to its right to provide the Company with a Notice of
          Demand (with a copy to AmWest) pursuant to clause (i) above).

Upon receipt of a Notice of Demand, the Company shall, subject to the provisions
of Sections 2.2(b) and 2.2(c), use Commercially Reasonable Efforts to effect at
the earliest practicable date the registration under the Securities Act of the
Registrable Securities that the Company has been so requested to register
pursuant to the Notice of Demand, for disposition in accordance with the
intended method or methods of disposition specified in the Notice of Demand.

          (b) Limitations on Demand Registration.  The Company shall not be
obligated to take any action to effect any registration pursuant to this Section
2.2:  (i) after the Company has, in accordance with the provisions of Section
2.4(c), effected (A) one (1) registration of Registrable Securities with respect
to a registration requested pursuant to Section 2.2(a)(i) or (B) one (1)
registration of Registrable Securities with respect to a registration requested
pursuant to Section 2.2(a)(ii); (ii) during any period in which the Company
would be permitted to suspend registration pursuant to the proviso in Section
2.1(b); (iii) during any period if the Company and GPA agree in writing to
suspend such registration for such period; or (iv) if (A) within fourteen (14)
days after the giving of a Notice of Demand, the Company causes to be delivered
to GPA and each transfer agent for the Registrable Securities an opinion of
counsel in form and substance reasonably acceptable to GPA, and acceptable to
each such transfer agent for the purpose of permitting the transfer by GPA of
securities proposed to be sold without registration under the Securities Act or
the legending of such securities, to the effect that the proposed disposition of
such securities by GPA will not require registration or qualification under the
Securities Act; provided, however that GPA will promptly furnish to the Company
and such counsel all information such counsel may reasonably request in order to
enable such counsel to determine whether it would be able to render such an
opinion and (B) promptly (and in any event within a further fourteen (14) days
thereafter) the Company causes to be delivered to GPA, in exchange for all of
GPA's Registrable Securities, new certificates therefor duly issued and not
bearing any legend restricting further transfer.

          (c) AmWest Demand Registration Rights.  If  the Company is unable to
furnish the opinion of counsel pursuant to Section 2.1(b)(iv) and if within
twenty-one (21) days after AmWest's receipt of a Notice of Demand by GPA, AmWest
(or any successor or other holder of such right) exercises its right to a demand
registration pursuant to Section 2.2(a) of the AmWest Registration Rights
Agreement, then GPA's Notice of Demand shall be deemed revoked; provided,
however that GPA shall have the right to request that the Company include
Registrable Securities held by GPA in the demand registration requested by
AmWest in accordance with and subject to Section 2.3 hereof and Section 2.2 of
the AmWest Registration Rights Agreement.  If a Notice of Demand made by GPA is
deemed revoked pursuant to this Section 2.2(c), the Company shall continue to be
obligated to effect a registration requested by GPA pursuant to Section 2.2(a).

<PAGE>
 
          (d) Notice to certain non-Requesting Holders.  Upon receipt of any
Notice of Demand from GPA, the Company will give prompt (but in any event within
fifteen (15) days after such receipt) notice to all Holders of Registrable
Securities and all other Holders of securities entitled to participate in such
registration including holders of Registrable Equity Securities under the AmWest
Registration Rights Agreement, of such Notice of Demand and of such Holders'
rights to have securities included in such registration (subject to priorities
in registration rights set forth in this Agreement and the AmWest Registration
Rights Agreement).  Upon the request of any such Holder made within fifteen (15)
days after the receipt by such Holder of any such notice (which request shall
specify the securities intended to be disposed of by such Holder and the
intended method or methods of disposition thereof), the Company will (subject to
any priorities in registration rights among the various Holders) use
Commercially Reasonable Efforts to effect the registration of all securities
which the Company has been so requested to register pursuant to the Notice of
Demand.

          (e) Priority in Demand Registrations.  If (i) a registration pursuant
to this Section 2.2 involves an underwritten offering of the securities being
registered 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 GPA 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 GPA, 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 GPA and its 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; second, such Registrable Securities
requested to be included in such registration by all other Holders of
Registrable Securities pro rata on the basis of the amounts of such securities
to be sold and so proposed to be sold and so requested to be included by such
Holders; third such Registrable Equity Securities requested to be included in
such registration by AmWest, Fidelity, Lehman Brothers Inc. ("Lehman") or any of
their respective Affiliates under the AmWest Registration Rights Agreement 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; and fourth, such Registrable Equity
Securities requested to be included in such registration by other Holders of
Registrable Equity Securities under the AmWest Registration Rights Agreement pro
rata on the basis of the amounts of such securities so proposed to be sold and
so requested to be included by such parties, and fifth, such other securities of
the Company whose holders have registration rights which would permit inclusion
in such offering and which are 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 holders.

          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
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 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 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 Efforts to effect the registration under the

<PAGE>
 
Securities Act of all Registrable 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 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 Registrable Securities in connection with such
registration (but not from its obligation to pay all Registration Expenses in
connection therewith as provided in Section 2.5(b)), without prejudice, however,
to the right of GPA 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 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 (except for any right to demand
registration which may be exercised pursuant to the last clause of subsection
(i) of the preceding sentence) or shall relieve the Company of its obligation to
effect any registration under such Sections.

          (b) Priority in Primary Piggyback Registrations.  If (i) a
registration pursuant to this Section 2.3 involves an underwritten offering of
the securities being registered 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 AmWest, Lehman, or any Fidelity Fund or any of their respective
Affiliates under the AmWest Registration Rights Agreement 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 other holders of such securities under the
AmWest Registration Rights Agreement 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; fourth, such Registrable Securities requested to be included in such
registration by GPA or any of its 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; fifth such Registrable 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
holders; and sixth, all other securities of the Company requested to be included
in such registration pro rata on the basis of the amount of such securities so
proposed to be sold and so requested to be included.

          (c) Priority in Secondary Piggyback Registrations.  If (i) a
registration pursuant to this Section 2.3 involves an underwritten secondary
offering of the securities being registered for sale for the account of AmWest,
Fidelity or any of their respective Affiliates or transferees pursuant to the
AmWest Registration Rights Agreement, 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 Persons
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 such Persons, then the Company will include in such

<PAGE>
 
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
securities proposed to be sold for the account of AmWest, Lehman, any Fidelity
Fund or any of their respective Affiliates under the AmWest Registration Rights
Agreement 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; second, such
Registrable Equity Securities requested to be included in such registration by
other holders of such securities under the AmWest Registration Rights Agreement
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
Securities requested to be included in such registration by GPA or any of its
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; fourth, such
Registrable 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 Holders, and fifth, all other
securities of the Company requested to be included in such registration pro rata
on the basis of the amount of such securities so proposed to be sold and so
requested to be included.

          2.4. Registration Terms and Procedures.

          (a) Registration Statement Form.  Registrations under Section 2.2
shall be on such appropriate registration forms of the SEC (i) as shall be
acceptable to GPA (such acceptance not to be unreasonably withheld) and (ii) as
shall permit the disposition of such Registrable Securities in accordance with
the intended method or methods of disposition.  The Company agrees to include in
any such registration statement all information that any Participating Holder
shall reasonably request (to the extent such information relates to such
Participating Holder).

          (b) Registration Expenses.  Subject to Section 2.4(f), the Company
will pay all Registration Expenses incurred in connection with a registration to
be effected (whether or not effected or deemed effected pursuant to subsection
(c) below) pursuant to Sections 2.1, 2.2 or 2.3.

          (c) Effectiveness of Demand Registration.  A registration will not be
deemed to have been effected under Section 2.2 unless the registration statement
with respect thereto has been declared effective by the SEC and, subject to the
proviso in Section 2.1(b) and to Section 2.5(g)(vii) hereof, remains effective
for the earlier of six (6) months or the distribution of the securities covered
by such registration statement; provided, however, that if (i) after such
registration statement has been declared effective, the marketing of Registrable
Securities offered pursuant to such registration statement is materially
disrupted or adversely affected as a result of any stop order, injunction or
other order or requirement of the SEC or any other governmental agency or court
(for reasons other than a misrepresentation or omission by GPA or any
Participating Holder) or (ii) the conditions to closing specified in the
purchase agreement or underwriting agreement entered into in connection with
such registration have not been satisfied (for reasons other than a wrongful or
bad faith act, omission or misrepresentation by GPA or any Participating
Holder), such registration statement will be deemed not to have become
effective.  If a registration pursuant to Section 2.2 is deemed not to have been
effected hereunder, then the Company shall continue to be obligated to effect a
registration pursuant to such Section.

          (d) Selection of Underwriter.  If, in connection with a registration
effected pursuant to Section 2.2, GPA so elects, the offering of Registrable
Securities pursuant to such Section shall be in the form of an underwritten
offering.  If GPA so elects, it shall select one or more nationally recognized
firms of investment bankers to act as the book-running managing underwriter or
underwriters in connection with such offering, provided that such selection
shall be subject to the consent of the Company, which consent shall not be
unreasonably withheld.

<PAGE>
 
          (e) Registration of Securities.  Participating Holders may seek to
register different types of Registrable Securities and/or different classes of
the same type of Registrable Securities simultaneously and the Company shall use
its, and in the case of an underwritten offering, shall cause the managing
underwriter or underwriters to use Commercially Reasonable Efforts to effect
such registration and sale in accordance with the intended method or methods of
disposition specified by such Holders.

          (f) Withdrawal.  Any Holder participating in a registration pursuant
to this Agreement shall be permitted to withdraw all or part of its Registrable
Securities from such registration at any time prior to the effective date of the
registration statement covering such securities; 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
2.4(c) unless (i) GPA and any Participating Holders shall have paid or
reimbursed the Company for fifty percent (50)% of the reasonable out-of-pocket
fees and expenses paid by the Company hereunder or (ii) GPA elects to terminate
such registration due to the occurrence of a Material Adverse Change; provided,
however, that during the term of this Agreement only one such withdrawal shall
be permitted pursuant to the preceding  proviso.

          (g) Registration Procedures.  In connection with the Company's
obligations to register Registrable Securities pursuant to this Agreement, the
Company will use Commercially Reasonable Efforts to effect such registration so
as to permit the sale of any Registrable Securities included in such
registration in accordance with the intended method or methods of distribution
thereof, and pursuant thereto the Company will as expeditiously as possible:

          (i) prepare and (as soon thereafter as practicable) file with the SEC
     the requisite registration statement containing all information required
     thereby to effect such registration and thereafter use Commercially
     Reasonable Efforts to cause such registration statement to become and
     remain effective in accordance with the terms of this Agreement, provided
     that as far in advance as practicable before filing such registration
     statement or any amendment, supplement or exhibit thereto (but, with
     respect to the filing of such registration statement, in no event later
     than seven (7) 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 information relating to such Holder or the plan
     of distribution of the Registrable Securities prior to filing any such
     registration statement, amendment, supplement or exhibit;

          (ii) prepare and file with the SEC such amendments and supplements to
     such registration statement and the prospectus used in connection therewith
     (A) as reasonably requested by any Participating Holder to which such
     registration statement relates (but only to the extent such 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 six (6)
     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 Securities Act with respect to the sale or other disposition of all
     securities covered by such registration statement during such period in
     accordance with the intended method or methods of disposition by the seller
     or sellers thereof set forth in such registration statement;

<PAGE>
 
          (iii)  furnish to each Holder covered by, and each underwriter or
     agent participating in the disposition of securities under, such
     registration statement such number of conformed copies of such registration
     statement and of each such amendment and supplement thereto (in each case
     excluding all exhibits and documents incorporated by reference, which
     exhibits and documents shall be furnished to any such Person upon request),
     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 Efforts to register or qualify all
     Registrable Securities and other securities covered by such registration
     statement under (A) with respect to the Shelf Registration Statement, all
     blue sky and other securities laws and (B) with respect to a registration
     effected pursuant to Section 2.2, all applicable blue sky and other
     securities laws, and to keep such registration or qualification in effect
     for so long as such registration 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 generally to do business as a foreign corporation in any
     jurisdiction 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 jurisdiction or (c) consent to general service of process in any
     jurisdiction;

          (v) use Commercially Reasonable 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 Registrable Securities covered by such
     registration statement a signed counterpart, addressed to such Holder (and
     underwriter or agent, if any) of:

               (A)  an opinion of counsel to the Company, 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), and

               (B)  unless otherwise precluded under applicable accounting
          rules, 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;

<PAGE>
 
          (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 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 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 Efforts to (A) list, on or prior to
     the effective date of such registration statement, all Registrable
     Securities covered by such registration statement on any securities
     exchange on which any of the Registrable 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 System of NASDAQ if the Registrable
     Securities so qualify;

          (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 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
     Efforts to cause such order to be lifted as promptly as practicable;

          (xiii)  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:

<PAGE>
 
               (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;

               (B) of any written comments from the SEC with respect to any
          filing referred to in clause (A) and of any written request by the SEC
          for amendments or supplements to such registration statement or
          prospectus;

               (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

               (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) 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); and

          (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.

          (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 GPA or any of its
Affiliates by name or otherwise as

<PAGE>
 
the holder of any securities of the Company, then such Holder shall have the
right to require that such reference be in a form reasonably satisfactory to
such Holder or 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) (the period from the date on which such Holder receives a Suspension
Notice to the date on which such Holder receives copies of the supplemented or
amended prospectus being herein called the "Suspension Period").  The Company
shall take such actions as are necessary to end the Suspension Period as
promptly as practicable.  In the event the Company shall give any such notice,
the periods referred to in Section 2.5(c) and 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.

          2.5.  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 GPA (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 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 2.7.  GPA (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.

          (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 Sections 2.3(b) and (c),
arrange for such underwriters to include all of the Registrable Securities to be
offered and sold by such Holder or Holders among the securities to be
distributed by such underwriters.  The Holders of Registrable 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 Company and the Requisite
Holders, and the Requisite Holders 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.

<PAGE>
 
          2.6.  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 underwriter s' or agents' respective counsel,
to conduct a reasonable investigation within the meaning of the Securities Act.

          2.7. 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 provided for as described herein (including,
without limitation, under the Shelf Registration Statement or any replacement
Shelf Registration Statement), its directors, officers, shareholders, employees,
investment advisers, agents and Affiliates, either direct or indirect (and each
such Affiliate's 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, to
the extent that 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 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

<PAGE>
 
     amended or supplemented prior to or concurrently with such sale after the
     Company had furnished such Indemnified Party (in accordance with the notice
     provisions contained in Section 10 for Persons who are parties to this
     Agreement) with a sufficient number of copies of the same for delivery 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.  (i)  The Company may require, as
a condition to including any Registrable Securities in any registration
statement filed pursuant to Sections 2.1, 2.2 or 2.3 and as a condition to
indemnifying such sellers pursuant to this Section 2.7, that the Company shall
have received an undertaking reasonably satisfactory to it from each prospective
seller of such securities, and (ii) each Holder participating in the Shelf
Registration Statement or any replacement Shelf Registration Statement agrees,
to indemnify and hold harmless and reimburse (in the same manner and to the same
extent as set forth in paragraph (a) of this Section 2.7) 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 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 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
2.7(b) shall be several, and not joint and several, among such indemnifying
parties.  Notwithstanding anything in this Section 2.7(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 2.7, 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 2.7, except to the extent that the indemnifying

<PAGE>
 
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 exists 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 one additional counsel
or firm of counsel for such indemnified 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 any Losses for any settlement made without its consent, which
consent shall not be unreasonably withheld.

          (d) Other Indemnification.  The provisions of this Section 2.7 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 2.7 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 2.7, 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 2.7(f) to the contrary, no
indemnifying party (other than the Company) shall be required pursuant to this
Section 2.7(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

<PAGE>
 
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.

          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 as GPA may reasonably request, all to the extent required from time to
time to enable GPA to sell 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 similar rule or regulation hereafter adopted by the
SEC.  Upon the request of GPA, the Company will deliver to GPA a written
statement as to whether it has complied with such requirements and will, at its
expense, forthwith upon the request of GPA, deliver to GPA a certificate, signed
by the Company's principal financial officer, stating (A) the Company's name,
address and telephone number (including area code), (B) the Company's Internal
Revenue Service identification number, (C) the Company's SEC file number, (D)
the amount of shares of each class of capital stock outstanding as shown by the
most recent report or statement published by the Company, and (E) whether the
Company has filed the reports required to be filed under the Exchange Act for a
period of at least ninety (90) days prior to the date of such certificate and in
addition has filed the most recent annual report required to be filed
thereunder.

          (b) If at any time the Company is not required to file reports in
compliance with either Section 13 or Section 15(d) of the Exchange Act, the
Company at its expense will, forthwith upon the request of GPA, (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 (d)(4)(ii) of Rule 144A).

          4.   Term.  This Agreement shall be effective on the date hereof and,
subject to Section 15 hereof, shall continue in full force and effect until the
eighth (8th) anniversary of the date hereof.

          5.   Amendments and Waivers.  This Agreement may be amended,
supplemented or modified at any time; provided that each of (i) GPA (so long as
GPA or its Affiliates hold Registrable Securities), (ii) the Holders (which may
include GPA) of at least fifty-one percent (51%) in interest of Registrable
Securities, 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 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 and their respective
Successors 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

<PAGE>
 
GPA, (ii) any Holder of Registrable Securities entitled to notice of the
registration of securities under this Agreement and (iii) any Participating
Holder entitled to indemnity under Section 2.7.

          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.   Notices.  All notices, requests and other communications
hereunder must be in writing and will be deemed to have been duly given only (i)

Act other than rights granted pursuant to the AmWest Registration Rights
Agreement.

<PAGE>
 
          14.  Attorneys' Fees.  In any action or proceeding brought to enforce
any provision of this Agreement or where any provision hereof is validly
asserted as a defense, the successful party shall, to the extent permitted by
applicable law, be entitled to recover reasonable attorneys' fees in addition to
any other available remedy.

          15.  Termination of Certain Rights and Obligations.  The rights and
obligations hereunder of GPA shall terminate with respect to GPA at such time as

such agreement, modification or waiver would conflict with the rights granted

term of this Agreement.

          17.  Specific Performance.  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 and (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.

          18.  Requisite Holders.  Each of the parties hereto agrees that the
Company may, in connection with the taking of any action permitted to be taken
hereunder with the consent or approval of the Requisite Holders of the
securities to be included in the relevant registration, rely in good faith on a
certificate from such holder or holders stating that it holds or is acting on
behalf of a majority in interest of such securities.

          19.  Counterparts.  This Agreement may be executed simultaneously in
any number of counterparts, each of which shall be deemed an original, but all
of which shall together constitute one and the same instrument.

<PAGE>
 
          IN WITNESS WHEREOF, the parties have caused this Agreement to be
executed and delivered by their respective officers thereunto duly authorized as

and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

1.0  DEFINITIONS.

         "Affiliate" shall mean (i) when used with reference to any partnership,
any person or entity that, directly or indirectly, owns or controls ten percent
(10%) or more of either the capital or profit interests of such partnership or
is a partner of such partnership or is a person or entity in which such
partnership has a ten percent (10%) or greater direct or indirect equity

entity that, directly or indirectly, owns or controls ten percent (10%) or more
of the outstanding voting securities of such corporation or is a person or
entity in which such corporation has a ten percent (10%) or greater direct or
indirect equity interest.  In addition, the term "Affiliate," when used with
reference to any person or entity, shall also mean any other person or entity
that, directly or indirectly, controls or is controlled by or is under common
control with such person or entity.  As used in the preceding sentence, (A) the
term "control" means the possession, directly or indirectly, of the power to
direct or cause the direction of the management and policies of the entity
referred to, whether through ownership of voting securities, by contract or

  controlled by them in favor of the removal from the Board, upon notice by the
  group or entity having the right to designate such director under this Section
  2.1 and requesting such removal, of any person or persons designated to the
  Board by such group or entity, and (ii) to vote the Common Stock held and
  controlled by them (other than stock held individually by any Stockholder
  Representative) and to cause (or in the case of the Stockholder
  Representatives, recommend to) the directors designated by them to vote or
  take such action as may be required under the General Corporation Law or
  otherwise to implement the provisions of this Agreement.  The group or entity
  who has nominated any director in accordance with this Agreement shall have

  covered by such filing covenants and agrees to promptly provide to AmWest all

  to notify AmWest of any changes in facts or circumstances pertaining to such
  party that would require any amendments under Regulation 13D-G.

         BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "1933
         ACT") OR PURSUANT TO THE SECURITIES LAWS OF ANY STATE, AND SUCH
         SECURITIES MAY NOT BE SOLD OR TRANSFERRED OTHER THAN IN ACCORDANCE WITH
         THE REGISTRATION REQUIREMENTS OF THE 1933 ACT AND THE RULES AND
         REGULATIONS THEREUNDER OR AN EXEMPTION THEREFROM AND FROM ANY
         APPLICABLE STATE SECURITIES LAWS.

         4.7  During the term of this Agreement, AmWest shall not cause the
  issuance of any preferred stock by the Company 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.

  5.0    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 transfer of
  securities subject to this Agreement to provide such information as may
  reasonably be requested by the Company regarding ownership of securities,
  affiliations, if any, between the party requesting transfer 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.

     in this Agreement, neither GPA nor AmWest shall be obligated to vote any
     Voting Securities for which the voting rights have been suspended, whether
     voluntarily or involuntarily.

          (e) Failure to Nominate.  In the event that AmWest or GPA shall fail
     or refuse to designate a

                                       5

<PAGE>
 
     nominee to the Board for a position allocated to such party, each of AmWest
     and GPA shall take such action, or cause such action to be taken, as is
     necessary to cause such position to remain vacant unless and until such
     designation shall be made in accordance with this Agreement.

          (f) Removal.  Each of GPA and AmWest agrees:

               (i) to vote the Voting Securities held and controlled by it, and,
          to its best efforts, cause each of its Affiliates to vote the Voting
          Securities held and controlled by each such Affiliate, in favor of the
          removal of any director from the Board upon written request by the
          party which nominated such director; and

               (ii) to vote the Voting Securities held and controlled by it,
          and, to its best efforts, cause each of its Affiliates to vote the
          Voting Securities held and controlled by each such Affiliate, and to
          cause the directors designated by it to vote or take such action as
          may be required under the General Corporation Law or otherwise to
          implement the provisions of this Agreement.

     The party who has nominated any director in accordance herewith shall have
     the exclusive right to remove or replace such director by written notice as
     provided herein; except that nothing in this Agreement shall be construed
     to limit or prohibit the removal of any director for cause.

          (g) Acceptability of GPA Nominee.  AmWest hereby agrees that for
     purposes of Section 2(b)(ii) of this Agreement and Section 2.1(c) of the
     Stockholder Agreement, each of Patrick Blaney, John Tierney and Declan
     Traecy is acceptable to AmWest in all respects as GPA Director.

     Section 3.  Covenants of AmWest.

     (a) AmWest Partners, L.P. hereby covenants and agrees that its constituent
documents shall require that this Agreement be binding at all times upon all
general and limited partners (other than Mesa) of AmWest Partners, L.P. and any
Affiliate of AmWest Partners, L.P. or such partners (other than Mesa) who hold
or receive any Voting Securities

                                       6

<PAGE>
 
or direct the voting of any Voting Securities held by AmWest, and upon any
assignees or transferees (other than Mesa) in a single transaction or a related
series of transactions consummated prior to the Release Date of all or
substantially all of the Voting Securities owned by AmWest or any of its
partners or Affiliates of AmWest or any of their partners and AmWest agrees that
it shall cause each such assignee and transferee to provide to GPA written
acknowledgement that it accepts and is bound and subject to the terms and
conditions of this Agreement (including, without limitation, the provisions of
Section 6(f) hereof); provided, however, the requirements set forth in this
Section 3(a) shall not apply to:

               (i) any Fidelity Fund or Lehman with respect to Class B Common
     Stock of AWA and warrants to purchase Class B Common Stock of AWA acquired
     by them contemporaneously with the consummation of the Plan pursuant to an
     assignment or transfer from AmWest; and

               (ii) any assignee or transferee who acquires such Voting
     Securities pursuant to (A) a tender or exchange offer open to all
     shareholders of AWA on a pro rata basis at the same price per share and on
     the same economic terms, (B) a public distribution or sale on the open
     market (1) through a "brokers' transaction", as such term is defined in
     subsection (g) of Rule 144 under the Securities Act or (2) registered under
     the Securities Act, including, without limitation, any shelf registration
     contemplated under the Plan, or (C) a transfer made pursuant to Rule 144
     under the Securities Act.

     (b) AmWest agrees that prior to the Release Date it shall not sell or
transfer (including, without limitation, upon dissolution of AmWest Partners,
L.P.) any Voting Securities held by it to any of its general or limited partners
(other than Mesa), to any Fidelity Fund, or to any Affiliate of AmWest or such
partners and AmWest shall not sell or transfer all or substantially all of the
Voting Securities held by it in a single transaction or a related series of
transactions (except in accordance with clauses (i) or (ii) of Section 3(a)(2)
hereof) unless and until it causes each such assignee and transferee to provide
a written acknowledgement to GPA that it accepts and is bound and subject to the
terms and conditions of this Agreement (including, without limitation, the
provisions of Section 6(f) hereof).

                                       7

<PAGE>
 
     (c) AmWest agrees that it shall not vote its stock in favor of, or permit
the AmWest Directors to vote for, the elimination of the position on the Board
reserved for the GPA Director.

     (d) AmWest agrees that it shall not transfer or assign (including, without
limitation, upon dissolution of AmWest Partners, L.P.) any Voting Security to
Mesa if after giving effect to any such transfer or assignment, Mesa shall hold
7% or more of the combined voting power of all Voting Securities then
outstanding.

     Section 4.  Rights Upon Breach.

     Each of AmWest and GPA recognizes and agrees that a violation of any term,
provision, or condition of this Agreement may cause irreparable damage to the
non-breaching party 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
party.  Each of AmWest and GPA therefore agrees that in the event of any breach
of this Agreement, the non-breaching party 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.

     Section 5.  Termination.

     (a) This Agreement shall automatically and immediately terminate without
any action by any party upon:

          (i) (A) the sale or transfer by GPA and/or its Affiliates of Voting
     Securities which results in the holding by GPA and/or its Affiliates of
     less than two percent (2%) of all Voting Securities on a fully diluted
     basis or (B) the occurrence of any other event which results in the holding
     by GPA and/or its Affiliates of less than two percent (2%) of all Voting
     Securities on a fully diluted basis if, and only if, (x) AWA files a Form
     10-Q under the Securities Exchange Act of 1934, as amended, or other
     written report or statement, that is delivered to GPA and copied to the
     party specified herein, which contains information as to AWA's total issued
     and outstanding Voting Securities as of a date therein specified (the
     "Determination Date") from which GPA can determine whether it holds less
     than two percent (2%) of all Voting Securities on a fully diluted basis and
     (y) GPA and/or its Affiliates fails to acquire (by purchase or otherwise)
     sufficient

                                       8

<PAGE>
 
     Voting Securities such that GPA and/or its Affiliates hold at least two
     percent (2%) of all Voting Securities on a fully diluted basis determined
     as of the Determination Date within thirty-five (35) days after the
     delivery of such Form 10-Q, or provision of such report or statement to GPA
     (notwithstanding anything to the contrary in this Agreement, GPA
     acknowledges that AWA continuing with its existing procedures for the
     distribution of Form-10-Qs to GPA constitutes adequate delivery to GPA
     within the meaning of this Section 5(a)(i)) and to give prompt notice of
     such acquisition to AmWest following the expiration of such thirty-five
     (35) day period;

          (ii) the occurrence of any event which results in the holding by
     AmWest and/or its Affiliates of less than five percent (5%) of all Voting
     Securities on a fully diluted basis; or

          (iii) the tenth anniversary of the Effective Date, provided that in
     the event Section 218(c) of the General Corporation Law of the State of
     Delaware shall have been amended or deleted, the latest date permitted
     under such amended section or any successor provision thereto, and provided
     further that in the event the laws of the State of Delaware shall cease to
     impose a time limit on the effectiveness of voting agreements among
     stockholders, this Section 5(a)(iii) shall cease to have any force or
     effect.

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 any such termination shall not relieve any person or entity from
liability for breach or default of this Agreement prior to such termination; and
provided further that GPA agrees that in the event this Agreement is terminated
pursuant to Section 5(a)(i) hereof, GPA shall cause the resignation of, or
provide notice to AmWest requesting that it take such actions as are necessary
to cause the removal of, the GPA Director.

     (b) In the event that the Stockholder Agreement is terminated or becomes
unenforceable or invalid, in whole or in part, for any reason, this Agreement
shall remain in full force and effect and the terms and conditions contained in
this Agreement shall not be affected in any manner by any such termination,
unenforceability or invalidity.

     (c) Each of the parties bound by this Agreement hereby agrees that so long
as both the Stockholder Agreement and this Agreement are in effect, nothing
contained in this Agreement shall be construed to limit or otherwise affect the
obligations, rights or remedies of any party under the Stockholder Agreement.
