ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145 of the Delaware General Corporation Law ("DGCL") authorizes,
inter alia, a corporation generally to indemnify any person ("indemnitee") who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding (other than an action by or in the right
of the corporation) by reason of the fact that such person is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation, in a similar position with another corporation or
entity, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him in connection
with such action, suit or proceeding if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. With respect to actions or
suits by or in the right of the corporation; however, an indemnitee who acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation is generally limited to attorneys' fees and
other expenses, and no indemnification shall be made if such person is adjudged
liable to the corporation unless and only to the extent that a court of
competent jurisdiction determines that indemnification is appropriate. Section
145 further provides that any indemnification shall be made by the corporation
only as authorized in each specific case upon a determination by the (i)
stockholders, (ii) board of directors by a majority vote of a quorum of
disinterested directors so directs, that indemnification of the indemnitee is
proper because he has met the applicable standard of conduct. Section 145
provides that indemnification pursuant to its provisions is not exclusive of
other rights of indemnification to which a person may be entitled under any
by-law agreement, vote of stockholders or disinterested directors or otherwise.
 
     Section 8.02 of the Company's By-laws, a copy of which is filed as Exhibit
3.2 to this Registration Statement provides, in substance, that directors,
officers, employees and agents shall be indemnified to the fullest extent
permitted by Section 145 of the DGCL.
 
     Article 12.0 of the Company's Restated Certificate of Incorporation, a copy
of which is filed as Exhibit 3.1 to this Registration Statement, limits the
liability of directors of the Company to the Company or its stockholders (in
their capacity as directors but not in their capacity as officers) to the
fullest extent permitted by the DGCL. Specifically, directors of the Company
will not be personally liable for monetary damages for
 
                                      II-1
<PAGE>   4
 
breach of a director's fiduciary duty as a director, except for liability (i)
for any breach of the director's duty of loyalty to the Company or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) for unlawful
payments of dividends or unlawful stock repurchase or redemptions as provided in
section 174 of the DGCL or (iv) for any transaction from which the director
derived an improper personal benefit. The Restated Certificate of Incorporation
also provides that if the DGCL is amended after the approval of the Restated
Certificate of Incorporation to authorize corporate action further eliminating
or limiting the personal liability of directors, then the liability of a
director of the Company will be eliminated or limited to the full extent
permitted by the DGCL, as so amended.
 
     The form of the Third Revised Investment Agreement filed as Exhibit 10.1 to
this Registration Statement contains certain provisions for indemnification of
directors and officers of the Company and the Selling Securityholder against
civil liabilities under the Securities Act.
 
     The Company intends to enter into indemnification agreements with certain
of its directors providing for indemnification to the fullest extent permitted
by the laws of the State of Delaware. These agreements provide for specific
procedures to better assure the directors' rights to indemnification, including
procedures for directors to submit claims, for determination of directors
entitled to indemnification (including the allocation of the burden of proof and
selection of a reviewing party) and for enforcement of directors'
indemnification rights.

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

results of operations and projections for future operations and for a summary
and analysis of the Plan of Reorganization and certain related matters.
 
     ALL HOLDERS OF CLAIMS AGAINST AND EQUITY INTERESTS IN THE DEBTOR ARE
ENCOURAGED TO READ THE PLAN OF REORGANIZATION AND THE DISCLOSURE STATEMENT IN
THEIR ENTIRETY BEFORE VOTING TO ACCEPT OR REJECT THE PLAN.

entitled to priority under Section 507(a)(1) of the Bankruptcy Code, including,
without limitation, fees payable pursuant to Section 1930 of Title 28 of the
United States Code, but not including the Post-Petition Agreement Claims. To the

not at any default or penalty rate of interest;
 
                   (ii) the maturity of the Claim shall be reinstated as such
maturity existed before any default;
 
                   (iii) the holder of the Claim shall be compensated for any

                   (iv) the other legal, equitable or contractual rights to
which the holder of the Claim is entitled shall not otherwise be altered;
provided, however, that as to any Allowed Secured Claim which is a nonrecourse

General Unsecured Claims.
 
          3.5.1. Each holder of an Allowed General Unsecured Claim shall receive
its Pro Rata Share of 26,775,000 shares of NewAWA Class B Common Stock;
provided, however, that if the holder is an Electing Unsecured Creditor in
accordance with Section 3.5.2, such holder shall receive Electing Creditor Cash
equal to $8.889 for each share of NewAWA Class B Common Stock otherwise
allocable to it under this sentence.
 
          3.5.2. A holder of an Allowed General Unsecured Claim may become an
Electing Unsecured Creditor only by providing notice of such election on the
Ballot which such holder submits. Any holder of a Disputed General Unsecured
Claim that wishes to become an Electing Unsecured Creditor must provide notice
to the Debtor of the exercise of such right by no later than the Voting
Deadline. Each such election by a holder of a General Unsecured Claim shall be
irrevocable and must pertain to the entire amount of such holder's General
Unsecured Claim. In the event that the aggregate amount of the Electing Creditor
Cash would be in excess of $100,000,000, then each Electing Unsecured Creditor
shall receive only its Pro Rata Share of $100,000,000 in Cash and shall also
receive a number of shares of Electing Creditor Stock equal to the number of
shares of NewAWA Class B Common Stock it would have received if it were a
Non-Electing Unsecured Creditor minus the result of dividing the Electing
Creditor Cash it receives by $8.889. For purposes of allocating Electing
Creditor Cash among Electing Unsecured Creditors, each Disputed General
Unsecured Claim held by an Electing Unsecured Creditor shall initially be valued
at its face amount; provided, however, in the event that the aggregate amount of
Electing Creditor Cash would exceed $100,000,000 and one or more holders of
Disputed General Unsecured Claims have become Electing Unsecured Creditors, then
any party in interest with regard thereto (including, without limitation, the
Creditors' Committee), may seek an order of the Bankruptcy Court estimating the
amount of any and all such Disputed General Unsecured Claims at a lower amount
and, then, regardless of the amount at which such Disputed General Unsecured
Claims are eventually Allowed, the holders thereof will be paid Electing
Creditor Cash in an amount which does not exceed the amount of Electing Creditor
Cash which would be payable for a Claim in the amount of such estimate and for
any amount of the Disputed Claim which is Allowed in excess of such estimate,
the holder shall receive Electing Creditor Stock in accordance with Section
10.4. NewAWA Class B Common Stock distributed to Non-Electing Unsecured
Creditors, Electing Creditor Stock and Electing Creditor Cash shall be
distributed in accordance with Section 10.2.
 
          3.5.3. Any holder of an Unsecured Claim asserting that payment to any
other holder of an Unsecured Claim should be subordinated to such first holder
under Section 510(a) of the Bankruptcy Code, may only make such assertion by
filing an adversary proceeding in the Chapter 11 Case on or before the Voting
Deadline, or such other date as may be established by Final Order of the
Bankruptcy Court. Any such subordination of one Unsecured Claim to another
Unsecured Claim shall be made only upon Final Order of the Bankruptcy Court and
no distribution hereby to any holder of an Allowed Claim which is the subject of
such an adversary proceeding shall be delayed or withheld except upon Final
Order of the Bankruptcy Court. Any such adversary proceeding involving holders
of AWA Debenture Claims shall name as defendants the Debtor and on behalf of all
such holders, the Indenture Trustee.
 
          3.5.4. Class 5 is impaired under the Plan.

Pro Rata Share of $500,000 in Cash plus the right to purchase as of the
Effective Date its Pro Rata Share of the first 250,000 shares of
Over-Subscription Stock at the price of $8.889 per share or such lesser amount
of Over-Subscription Stock as is available after the purchase of Equity
Subscription Stock in accordance with Section 3.6.2. Such Cash shall be
distributed in accordance with Section 10.1. Payment for such Over-Subscription
Stock shall be made no later than the Effective Date. Such Cash and rights shall
be deemed to be in full satisfaction for all Claims and Equity Interests arising
in connection with the AWA Preferred Stock including accrued and unpaid
dividends thereon. Class 6.1 is impaired under the Plan. All shares of AWA
Preferred Stock shall be deemed to be cancelled, annulled and extinguished on
the Effective Date.

          3.6.2. Class 6.2 -- AWA Common Stock.
 
               (a) This Class consists of shares of AWA Common Stock other than
shares of AWA Common Stock which are pledged as collateral for Employee Stock
Purchase Notes. Each holder of such AWA Common Stock shall receive its Pro Rata
Share of (i) the Equity Interests Stock and (ii) the Equity Interests Warrants,
to be distributed in accordance with the procedure set forth in Section 10.2.
 
               (b) Additionally, each such holder of AWA Common Stock other than
the holder of a Disputed Equity Interest shall have the right to purchase its
Pro Rata Share of the Equity Subscription Stock at the price of $8.889 per
share; provided, however, that for purposes of determining such Pro Rata Share
there shall be considered to be an aggregate of 22,100,000 shares of AWA Common
Stock outstanding. Such right is not transferrable and may only be exercised by
the beneficial holder of such AWA Common Stock as of the Voting Record Date by
the irrevocable indication thereof on the Ballot which such holder delivers or
causes to be delivered. Each such holder may also indicate on the Ballot that it
wishes to purchase Over-Subscription Stock, if available. The Over-Subscription
Stock available to Purchasing Stockholders shall consist of the Equity
Subscription Stock not subscribed for in accordance with the second preceding
sentence and less the Over-Subscription Stock sold to holders of AWA Preferred
Stock in accordance with Section 3.6.1. Each Purchasing Stockholder must
irrevocably indicate on the Ballot the maximum number of shares of Equity
Subscription Stock and Over-Subscription Stock which it desires to purchase. As
set forth more fully in Section 10.2, either full payment or a satisfactory
guarantee of payment for all Equity Subscription Stock and Over-Subscription
Stock must be delivered by the Voting Deadline. The procedure for allocating
Over-Subscription Stock is set forth in Section 10.2.
 
               (c) Class 6.2 is impaired under the Plan. All shares of AWA
Common Stock will be cancelled, annulled and extinguished on the Effective Date.

under one or more Employee Stock Purchase Notes. This Class also includes AWA
Common Stock pledged as collateral for Employee Stock Purchase Notes. Each
holder of an Allowed Claim or Equity Interest in this Class shall receive in
exchange for and in consideration of the dismissal with prejudice and permanent
enjoinment of the Securities Actions, a release of any and all indebtedness
incurred under the Employee Stock Purchase Plan, including the forgiveness,
abandonment and cancellation of any liability under the Employee Stock Purchase
Notes, but shall receive no other distribution under the Plan. In addition, all
liens on AWA Common Stock securing Employee Stock Purchase Notes will be
released and such AWA Common Stock will be returned to AWA and cancelled,
annulled and extinguished as of the Effective Date and will not be entitled to
any distribution under Section 3.6.2. Pursuant to Sections 1123(a)(5)(E), (F)
and 1123(b)(3)(A) of the Bankruptcy Code, the treatment provided Class 7.1
Claims constitutes a compromise and settlement of the Securities Action and any
and all objections to such Claims. The Debtor will either file appropriate
pleadings seeking to effect the treatment provided Class 7.1 Claims in this
Section 3.7.1 as a compromise and settlement prior to the Confirmation Hearing
or request the Bankruptcy Court to approve this compromise and settlement at the
Confirmation Hearing as in the best interests of the Debtor and holders of
Claims and Equity Interests and fair, equitable and reasonable. Class 7.1 is
impaired under the Plan.
 
          3.7.2. Certain AWA Warrants, Options and Other Equity Interests and

(except to the extent they are included in Class 7.1): (i) AWA Warrants,

(iii) Subordinated Claims and (iv) all Claims, if any, arising from the
cancellation or rejection (to the extent they constitute executory contracts) of

Equity Interests will not be entitled to receive or retain any property under
the Plan on account of such Claims or Equity Interests, and pursuant to Section
1126(g) of the Bankruptcy Code, are deemed not to have accepted the Plan. Class
7.2 is impaired under the Plan. All AWA Warrants, Options and Other Equity
Interests will be cancelled, annulled and extinguished on the Effective Date.

                    EXECUTORY CONTRACTS AND UNEXPIRED LEASES
 
     5.1. Assumption of Certain Executory Contracts and Unexpired Leases.
 
          5.1.1. Except as otherwise provided in the Plan or in any contract,
instrument, release, indenture or other agreement or document entered into in
connection with the Plan, on the Effective Date, pursuant to Section 365 of the
Bankruptcy Code, AWA shall assume or assume and assign, as indicated, each of
the Assumed Agreements including, without limitation, the executory contracts
and unexpired leases listed on Schedule 3 hereto; provided, however, that AWA or
NewAWA shall have the right, at any time prior to the Effective Date, to amend
Schedule 3: (a) unless indicated otherwise on Schedule 3, to delete any
executory contract or unexpired lease listed therein, thus providing for its
rejection pursuant to Section 5.2; or (b) to add any executory contract or
unexpired lease, thus providing for its assumption or assumption and assignment
pursuant to this Section 5.1.1. The Debtor or NewAWA shall provide notice of any
amendments to Schedule 3 to the parties to the executory contracts or unexpired
leases affected thereby and, if such amendments are made before the Effective
Date, to the parties on the Official Service List. Pursuant to Section
1123(b)(2) of the Bankruptcy Code, the Confirmation Order shall constitute an
order of the
 
                                       16
<PAGE>   23
 
          Bankruptcy Court approving the assumptions and assignments described
in this Section 5.1.1, pursuant to Section 365 of the Bankruptcy Code, as of the
Effective Date.
 
          5.1.2. Unless otherwise agreed by AWA and the counterparty to any such
Assumed Agreement, (i) all cure payments which may be required by Section
365(b)(1) of the Bankruptcy Code under any Assumed Agreement, if not previously
made, shall be made on the Effective Date or promptly thereafter, and (ii) in
the event of a dispute regarding the amount or timing of any cure payments, the
ability of NewAWA to provide adequate assurance of future performance, or any
other matter pertaining to assumption or assignment, such dispute shall be
resolved by the Bankruptcy Court and NewAWA shall make such cure payments, if
any, or provide such assurance as may be required by the Final Order resolving
such dispute on the terms and conditions of such Final Order.
 
          5.1.3. Except as otherwise provided in the Plan (including any such
provision on Schedule 3) or in any contract, instrument, release or indenture or
other agreement or document entered into in connection with the Plan, each
Assumed Agreement shall, at AWA's option, be assumed only to the extent that any
such contract or lease constitutes an executory contract or unexpired lease.
Listing a contract or lease on Schedule 3 shall not, in and of itself,
constitute an admission by the Debtor or NewAWA that such contract or lease is
an executory contract or unexpired lease or that the Debtor or NewAWA has any
liability thereunder. Contracts and leases which are within the definition of
Assumed Agreements and which are later determined to have not been in fact
executory contracts or unexpired leases, shall be treated in accordance with the
provisions in the Plan for the treatment of that type of Claim which properly
arises from the true nature of the legal relationship between the parties as
determined by the Bankruptcy Court or by settlement; provided, however, that
either the Debtor or NewAWA may in its sole discretion amend the Plan to provide
for different treatment of any such Claim after Notice and a Hearing.
 
          5.1.4. Except as otherwise provided in the Plan (including any such
provision on Schedule 3) or in any contract, instrument, release or indenture or
other agreement or document entered into in connection with the Plan, all
assumptions of executory contracts and unexpired leases under the Plan shall be
without prejudice to the rights of the Debtor or NewAWA to assign later such
assumed executory contracts or unexpired leases, notwithstanding any prohibition
to the contrary in any such contract or lease.
 
     5.2. Rejection of Certain Executory Contracts and Unexpired Leases. On the
Effective Date, except for every Assumed Agreement, each executory contract and
unexpired lease entered into by AWA prior to the Petition Date that has not
previously expired or terminated pursuant to its own terms and (to the extent
they are executory contracts) all AWA Warrants, Options and Other Equity
Interests shall be rejected pursuant to Sections 365 and 1123(b)(2) of the
Bankruptcy Code and considered a Rejected Agreement hereunder.
 
     5.3. Claims Based on Rejection of Executory Contracts or Unexpired Leases.
All proofs of claim with respect to Claims arising from the rejection of any
Rejected Agreement shall be filed with the Bankruptcy Court within the later to
occur of thirty (30) days after the Effective Date. Any Claims not filed within
such time shall be forever barred from assertion against the Debtor, its estate
and property, or NewAWA.

                 BY THE PLAN AND THE CLASS OF CLAIMS AND EQUITY
                   INTERESTS DEEMED TO HAVE REJECTED THE PLAN
 
     6.1. Unimpaired Classes. Claims in Classes 1, 2 and 4 are not impaired
under the Plan. Any Class not specifically designated in the Plan as unimpaired
is impaired under the Plan. Claims in unimpaired Classes are not entitled to
vote on the Plan.
 
     6.2. Class Deemed to Have Rejected the Plan. Claims and Equity Interests in
Class 7.2 are not entitled to receive or retain any property under the Plan and
are therefore deemed not to have accepted the Plan, and such Class shall not be
entitled to vote on the Plan.

     6.3. Other Impaired Classes. Claims in Classes 3.1, 3.2, 3.3, 3.4, 3.5,
3.6, 5, 6.1, 6.2 and 7.1 are impaired under the Plan and shall be entitled to
vote on the Plan.

                      ACCEPTANCE OR REJECTION OF THE PLAN;
                   EFFECT OF REJECTION BY ONE OR MORE CLASSES
 
     7.1. Impaired Classes to Vote. Except as otherwise required by the
Bankruptcy Code or the Bankruptcy Court, each holder of a Claim or Equity
Interest that is impaired under the Plan is entitled to vote to accept or reject
the Plan if, as of the Voting Record Date, (i) its Claim is an Allowed Claim,
(ii) its Claim has been temporarily allowed for voting purposes only by order of
the Bankruptcy Court pursuant to Bankruptcy Rule 3018 (in which case such Claim
may be voted in such temporarily allowed amount), (iii) its Claim has been
scheduled by the Debtor (but only if such Claim is not scheduled as disputed,
contingent or unliquidated) and no objection to such Claim has been filed, (iv)
it has filed a proof of claim on or before the Bar Date (or such later date as
the Bankruptcy Court may have established with respect to any particular Claim,
but not later than the date of the order approving such Disclosure Statement),
and such Claim is not a Disputed Claim, or (v) its Equity Interest is registered
on the stock ledger or equivalent of the Debtor. Notwithstanding the foregoing,
a holder of a Disputed Claim which has not been temporarily allowed as provided
above may nevertheless vote such Disputed Claim in an amount equal to the
portion, if any, of such Claim which is not disputed and is shown as fixed,
liquidated and undisputed in the Debtor's Schedules or such amount which the
Debtor concedes is Allowed in a filing made by the Debtor in the Bankruptcy
Court. Each holder of an AWA Debenture Claim, and not the Indenture Trustee with
respect to such Claim, shall have the right to vote to accept or reject the
Plan.
 
     7.2. Acceptance by Class of Holders of Claims or Equity Interests. A Class
of holders of Claims shall have accepted the Plan if the Plan is accepted by at
least two-thirds in amount and more than one-half in number of the Allowed
Claims of such Class that have voted to accept or reject the Plan. A Class of
Equity Interests shall have accepted the Plan if acceptance is voted for by the
holders of at least two-thirds in amount of the Equity Interests of such Class
who have voted to accept or reject the Plan.
 
     7.3. Cramdown. Inasmuch as Class 7.2 is deemed not to have accepted the
Plan in accordance with Section 1129(a) of the Bankruptcy Code, and in the event
that one or more other Classes of impaired Claims or Equity Interests does not
accept or is deemed not to have accepted the Plan, the Debtor requests that the
Bankruptcy Court confirm the Plan in accordance with Section 1129(b) of the
Bankruptcy Code. AWA and AmWest reserve the right to modify the Plan to the
extent, if any, that confirmation pursuant to Section 1129(b) of the Bankruptcy
Code requires or permits such modification.

          8.6.1. On the Effective Date, in consideration for services rendered

including the formulation, preparation, dissemination, implementation or
confirmation of the Plan or the Disclosure Statement or any contract,
instrument, release or other agreement or document created or entered into, or
any other act taken or omitted to be taken in connection therewith, and the
Debtor is enjoined from asserting any such claim or cause of action in any court
or forum; provided, however, that this provision shall not operate as a release,
waiver or relinquishment of, or injunction against asserting, any such claims or
causes of action (i) provided in or contemplated by the Plan or (ii) arising
from any actual fraud (but not constructive fraud) or willful misconduct of any
such Person.
 
          8.6.2. On the Effective Date, in consideration for benefits realized
in the Chapter 11 Case, the Debtor shall be deemed to have finally and
irrevocably waived, released and relinquished any and all claims and causes of
action, if any, that it has or may have against AmWest, any of AmWest's
partners, Fidelity or Lehman or their respective partners, affiliates, employees
or professional advisors arising out of or related to such Person's actions or
omissions to act in connection with the Chapter 11 Case, including the

Plan or the Disclosure Statement or any contract, instrument, release or other
agreement or document created or entered into, or any other act taken or omitted
to be taken in connection therewith, and the Debtor is enjoined from asserting
any such claim or cause of action; provided, however, that this provision shall
not operate as a release, waiver or relinquishment of, or injunction against
asserting, any such claims or causes of action (i) provided in or contemplated
by the Plan, (ii) arising from any actual fraud (but not constructive fraud) or
willful misconduct of any such Person, and (iii) reserved to the Debtor pursuant
to the Investment Agreement or the Interim Procedures Agreement.
 
          8.6.3. On the Effective Date, the Creditors' Committee and each member
thereof, the Equity Committee and each member thereof, AmWest and each of its
partners, Fidelity and Lehman shall be deemed to have finally and irrevocably
waived, released and relinquished any and all claims and causes of action, if
any, that any of them have or may have against the Debtor or its professional
advisors arising out of or related to such Person's actions or omissions to act
in connection with the Chapter 11 Case, including the formulation, preparation,
dissemination, implementation or confirmation of the Plan or the Disclosure
Statement or any contract, instrument, release or other agreement or document
created or entered into, or any other act taken or omitted to be taken in
connection therewith, and such Persons are enjoined from asserting any such

operate as a release, waiver or relinquishment of, or injunction against
asserting any such claims or causes of action (i) provided in or contemplated by
the Plan, (ii) arising from any actual fraud (but not constructive fraud) or
willful misconduct of the Debtor, and (iii) reserved to AmWest and/or any of its

Agreement; and, provided, further, this Section 8.6.3 shall not apply to any
claims made against the Debtor arising from third party claims against the
Creditors' Committee or any member thereof or the Equity Committee or any member
thereof. Any Person who as of the Effective Date is or was an officer or
director of AWA, shall be a beneficiary of the releases provided under Section
8.6.3 if such Person, no later than the Effective Date, delivers a release in
substantially the form of Sections 8.6.1 and 8.6.2.
 
     8.7. Indemnification Obligations.
 
          8.7.1. Upon, and at all times after the Effective Date, the NewAWA
Charter shall contain provisions which (i) eliminate the personal liability of
AWA's former, present and future directors for monetary damages resulting from
breaches of their fiduciary duties to the fullest extent permitted by
 
                                       19
<PAGE>   26
 
applicable law and (ii) require NewAWA, subject, to appropriate procedures, to
indemnify AWA's former, present and future directors and executive officers to
the fullest extent permitted by applicable law.
 
          8.7.2. On or as of the Effective Date, NewAWA shall enter into written
agreements with each person who is a director or executive officer of AWA as of
the date of the Investment Agreement providing for similar indemnification of
such person and providing that no recourse or liability whatsoever with respect
to the Investment Agreement, the Plan or the consummation of the transactions
contemplated hereby or thereby shall be had, directly or indirectly, by or in
the right of AWA against such person.
 
          8.7.3. For purposes of the Plan, except as limited hereinafter, any
obligations of the Debtor to indemnify its current and former directors,
officers, employees, and any officer, director or employee serving as a
fiduciary of any employee benefit plan or program of AWA, pursuant to charter,
by-laws, contract or applicable state law shall be deemed to be, and may be
treated as though they are, executory contracts that are Assumed Agreements
under the Plan, and such obligations (subject to any defenses thereto) shall
survive confirmation of the Plan and remain unaffected thereby, irrespective of
whether indemnification is owed in connection with a pre-Petition Date or
post-Petition Date occurrence; provided however, that the foregoing assumption
shall not affect any release of such obligations given to the Debtor before the
Effective Date or to NewAWA on or after the Effective Date.
 
     8.8. Exemption from Certain Taxes. Pursuant to Section 1146(c) of the
Bankruptcy Code, none of the transactions contemplated to take place on the

and all property of the Debtor's estate (including without limitation, all
rights of the Debtor to recover property under Sections 542, 543, 550 and 553 of
the Bankruptcy Code, all Avoidance Litigation and all proceeds thereof) and any
property acquired by AWA or NewAWA under or in connection with the Plan shall
vest or revest in NewAWA, in each case free and clear of all Claims, liens,
charges, encumbrances or Equity Interests, other than as specifically set forth
in the Plan. The Plan does not contain any restrictions or prohibitions on the
conduct of the business of NewAWA and NewAWA shall have all of the powers of a
corporation under the Delaware General Corporation Law, consistent with its
obligations under the Stockholders' Agreement. From and after the Effective
Date, NewAWA may use, operate and deal with its assets, and may conduct and
change its business, without any supervision by the Bankruptcy Court or the
Office of the United States Trustee, and free of any restrictions imposed on the
Debtor by the Bankruptcy Code or by the Bankruptcy Court during the Chapter 11
Case. Nothing contained in this Section shall be construed to prohibit, limit,
restrict or condition the Debtor's authority in any lawful manner to sell or
otherwise dispose of any other assets.
 
     8.11. Implementation. The Debtor and AmWest shall be authorized and are
directed to take all necessary steps, and perform all necessary acts, to
consummate the terms and conditions of the Plan, including, without limitation,
the Investment Agreement.
 
     8.12. Cancellation of Securities. As of the Effective Date, all previously
issued and outstanding securities of the Debtor, including without limitation:
all AWA Common Stock, all AWA Preferred Stock, all AWA Warrants, Options and
Other Equity Interests and all AWA Debentures; any certificate or other
instrument evidencing any such security; except as otherwise specifically
provided in Section 10.3 hereof, any indenture relating to any of the foregoing;
and the Debtor's obligations thereunder shall be deemed void, cancelled, and of
no further force or effect, without any further action on the part of any
Person. Holders of Allowed Claims and Equity Interests represented by such
securities shall have such rights to receive distributions as are set forth in
the Plan.

     Confirmation Order shall be in effect;

     contemplated by the Investment Agreement shall have been simultaneously
     consummated; and
 
          (c) Each of the conditions precedent to the obligations of the Debtor

                 PROVISIONS COVERING DISTRIBUTIONS AND PAYMENTS
 
     10.1. Making of Distributions and Payments. NewAWA, or a Distribution Agent
on its behalf, shall make the payments and distributions expressly required to
be made by it in respect of the Post-Petition Agreement Claims, Allowed
Administrative Claims (other than Preserved Ordinary Course Administrative
Claims), Allowed Priority Wage Claims, Allowed Priority Benefit Plan
Contribution Claims, Allowed Priority Tax Claims, Allowed Convenience Claims and
AWA Preferred Stock upon the latest of (i) the Effective Date, or as soon
thereafter as practicable, (ii) such date as may be fixed by the Bankruptcy
Court, or as soon thereafter as practicable, (iii) the fifth Business Day after
such Claim is Allowed, or as soon thereafter as practicable, and (iv) such date
as the holder of such Claim and NewAWA have agreed or shall agree.
 
     10.2. Distributions by the Distribution Agent.
 
          10.2.1. On the Effective Date, NewAWA will issue in the name of the
Distribution Agent, as trustee, the Non-Electing Creditor Stock for distribution
to Non-Electing Unsecured Creditors in accordance with Section 3.5, and the
Electing Creditor Stock for distribution to Electing Unsecured Creditors in
accordance with Section 3.5. Additionally, NewAWA will deliver to the
Distribution Agent the Electing Creditor Cash for distribution to Electing
Unsecured Creditors in accordance with Section 3.5. As promptly as practicable
after the issuance of such NewAWA Securities and delivery of Electing Creditor
Cash to the Distribution Agent, the Distribution Agent will distribute such
securities and Cash to the holders of Allowed Claims entitled thereto in
accordance with Section 3.5, but shall reserve from such distributions the
Reserve Amount as required by Section 10.4.
 
          10.2.2. Not later than thirty (30) days after the Voting Deadline, the
Debtor shall allocate among the Purchasing Stockholders, the Equity Subscription
Stock and the Over-Subscription Stock in accordance with this Section 10.2.2 and
advise the Distribution Agent of such allocation. Each Purchasing Stockholder
shall be allocated initially the lesser of (i) the number of shares for which it
has made a valid purchase election on its Ballot and (ii) its Pro Rata Share of
the Equity Subscription Stock. Holders who hold shares of AWA Common Stock for
the account of others such as brokers, trustees or depositories may only
exercise the right to purchase Equity Subscription Stock and Over-Subscription
Stock upon receipt of instructions and appropriate payment or guarantee of
payment from the beneficial owners of such shares as of the Voting Record Date.
The shares of Equity Subscription Stock not allocated as above will be
considered Over-Subscription Stock and will be allocated first to holders of AWA
Preferred Stock in accordance with Section 3.6.1 and then to holders of AWA
Common Stock who have indicated on the Ballot that they wish to acquire more
than their Pro Rata Share of the Equity Subscription Stock. If sufficient shares
of Over-
 
                                       21
<PAGE>   28
 
Subscription Stock are available, all subscriptions therefor will be honored in
full. If sufficient shares of Over-Subscription Stock are not available to honor
all such subscriptions, the available shares of Over-Subscription Stock will be
allocated among those who subscribed based on their proportional number of
shares of AWA Common Stock. The allocation process may involve a series of
allocations in order to assure that the total number of shares of
Over-Subscription Stock is distributed on a Pro Rata Share basis. The right to
purchase Equity Subscription Stock and Over-Subscription Stock may be exercised
through a holder's broker, who may charge such holder a servicing fee in
connection with such exercise. No such fees shall be paid by the Debtor or
NewAWA. The Debtor shall establish the Stock Payment Escrow Account for the
purpose of receiving payment for Equity Subscription Stock and Over-Subscription
Stock, which shall be held by the Escrow Agent or another bank, trust company or
other organization independent of AWA and designated by the Debtor and approved
by the Bankruptcy Court. Purchasing Stockholders may choose one of the following
methods of payment:
 
          (a) The Purchasing Stockholder may deliver full payment for the Equity
     Subscription Stock and the Over-Subscription Stock, together with its
     Ballot, with the check made payable to AWA Subscription Stock Escrow
     Account, by no later than the Voting Deadline. The Debtor shall deposit all
     such checks in the Stock Payment Escrow Account with any interest thereon
     to accrue to the benefit of Debtor or NewAWA pending distribution of the
     Equity Subscription Stock and Over-Subscription Stock; or
 
          (b) The Purchasing Stockholder may deliver or cause to be delivered to
     the Escrow Agent, by no later than the Voting Deadline, a notice of
     guaranteed delivery by telegram or otherwise, from a bank or trust company
     or a New York Stock Exchange member firm, guaranteeing delivery of payment
     of the full price of the subscribed for Equity Subscription Stock and
     Over-Subscription Stock. In such case, full payment for the Equity
     Subscription Stock and the Over-Subscription Stock (as such amount may be
     reduced as set forth below) must be received by the Escrow Agent by no
     later than 5:00 p.m. on the fifth Business Day after the Confirmation Date.
 
Promptly after completing the allocation required by the first sentence of this
Section 10.2.2, a confirmation will be sent to each Purchasing Stockholder
showing the number of shares of Equity Subscription Stock and the number of
shares, if any, of Over-Subscription Stock allocated to such holder. In the
event that such number of shares of Over-Subscription Stock is less than the
number of shares of Over-Subscription Stock for which such holder has either
paid for or guaranteed payment for, such notice shall also state such fact and
if full payment shall have already been made for such stock, such notice shall
also include a check representing the excess payment. Whichever of the two above
methods of payment is used, issuance and delivery of the Equity Subscription
Stock, the Over-Subscription Stock and any refunds of payments therefor shall be
subject to collection of checks and actual payment pursuant to any notice of
guaranteed delivery. All offers to purchase Equity Subscription Stock and
Over-Subscription Stock shall be irrevocable. In the event that the Effective
Date has not occurred by the date the Interim Procedures Agreement is
terminated, all amounts in the Stock Payment Escrow Account (other than interest
accrued thereon) shall be returned to the Purchasing Stockholders who have made
payment for the Equity Subscription Stock and/or Over-Subscription Stock.
 
          10.2.3. On the Effective Date, NewAWA will issue in the name of the
Distribution Agent, as trustee, (i) the number of shares of Equity Subscription
Stock and Over-Subscription Stock to be issued to Purchasing Stockholders and
holders of AWA Preferred Stock in accordance with Sections 3.6.1, 3.6.2 and
10.2.2, and (ii) the Equity Interests Stock and the Equity Interests Warrants
for distribution to holders of AWA Common Stock as provided in Section 3.6.2. As
promptly as practicable after the Effective Date, but in any event within
fifteen (15) Business Days, the Distribution Agent will distribute (i) to each
holder of AWA Preferred Stock, the number of shares of Over-Subscription Stock
purchased in accordance with Section 3.6.1, (ii) to each Purchasing Stockholder,
the number of shares of Equity Subscription Stock and Over-Subscription Stock
purchased by such Purchasing Stockholder pursuant to Section 3.6.2 and (iii) to
each holder of AWA Common Stock as of the Distribution Record Date other than
the holder of a Disputed Equity Interest, such holder's Pro Rata Share of the
Equity Interests Stock and of the Equity Interests Warrants, less any Reserve
Amount required pursuant to Section 10.4; provided, however, that holders of AWA
Common Stock whose stock is held of record by Cede or by any other depository or
nominee on their behalf or their
 
                                       22
<PAGE>   29
 
broker-dealer's behalf will have their NewAWA Securities credited to the account
of Cede or such other depository or nominee.
 
          10.2.4. The Distribution Agent in its capacity as trustee holding
issued but undistributed NewAWA Securities and Electing Creditor Cash shall (i)
similarly hold in trust for distribution pursuant to this Section 10.2 any
dividend or distribution made thereon, and (ii) whenever any matter (including
election of directors) is presented for a vote by holders of such NewAWA
Securities, vote all of the NewAWA Securities so held by it in trust in the same
manner and proportion as the shares of NewAWA Class B Common Stock are voted.
 
          10.2.5. If, after the Effective Date, NewAWA (i) pays a dividend or
makes a distribution on the outstanding NewAWA Securities held by the
Distribution Agent, (ii) subdivides the outstanding shares of NewAWA Securities
held by the Distribution Agent into a greater number of shares or units, (iii)
combines the outstanding shares or units of NewAWA Securities held by the
Distribution Agent into a smaller number of shares or units, (iv) issues by
reclassification of the outstanding NewAWA Securities held by the Distribution
Agent any shares of its capital stock, or (v) is a party to a consolidation,
merger or transfer of assets providing for any change in or exchange of the
outstanding NewAWA Securities held by the Distribution Agent, then the
Distribution Agent's obligation to distribute NewAWA Securities to any holder of
an Allowed Claim or Equity Interest arising after the record date in the case of
a dividend or distribution and after the Effective Date of any of the other
foregoing transactions shall be adjusted so as to take into account such
dividend, distribution or other event. Any such distribution shall be made net
of any Distribution Agent Charges incurred in connection with such event.
 
          10.2.6. The duties of the Distribution Agent (including its duties as
trustee pursuant to this Section 10.2) are expressly limited to the ministerial
functions set forth in this Article 10. The Distribution Agent shall incur no
liability for its actions (or failure to act) or conduct as Distribution Agent,
or as trustee holding issued but undistributed NewAWA Securities or Cash except
to the extent attributable to the gross negligence or willful misconduct of the
Distribution Agent. The Distribution Agent shall at all times maintain a
segregated account for any Cash being held in trust, and shall deposit or invest
all such Cash in (i) direct obligations of the United States of America or
obligations for which the full faith and credit of the United States of America
is pledged, (ii) certificates of deposit and interest bearing deposits with
banks having a long-term bond rating of AA or better and capital, surplus and
undivided profits of not less than $100,000,000, or (iii) commercial paper
having one of the two highest ratings by Standard & Poor's, Inc. or Moody's
Investor Services, Inc., except as otherwise authorized by the Bankruptcy Court;
provided, however, that no such deposit or investment shall have a maturity of
more than 90 days. All Distribution Agent Charges shall be deducted from the
applicable NewAWA Securities or Cash held by the Distribution Agent. All Cash
and NewAWA Securities held by or transferred to the Distribution Agent for
distribution to holders of Allowed Claims or Equity Interests pursuant to the
Plan shall be held by the Distribution Agent (including NewAWA in its capacity
as Distribution Agent) solely as trustee of an express trust and shall not be or
constitute property of the Distribution Agent (including NewAWA as Distribution
Agent) for any purpose whatsoever, and the Distribution Agent shall not have any
right or interest to any such Cash or stock for its own account, except as
expressly provided in the Plan.
 
          10.2.7. AWA shall deliver to the Distribution Agent its stock ledger
for the AWA Common Stock or provide access thereto, which ledger shall reflect
the cancellation of certain AWA Common Stock in accordance with Section 3.7.1.
The Distribution Agent shall cause a register for the transfer of Allowed Claims
(other than Allowed AWA Debenture Claims) and of AWA Common Stock to be
maintained. Transfers after the Distribution Record Date shall be registered
only (i) upon Final Order of the Bankruptcy Court directing such transfer or
(ii) in the event of a transfer by operation of law.
 
     10.3. Service of Indenture Trustee.
 
          10.3.1. Subject to the right of the Indenture Trustee to resign and
terminate an Indenture as set forth in Section 10.3.2, the Indenture Trustee
shall receive and act as disbursing agent for all distributions to each holder
of record of an Allowed AWA Debenture Claim. Unless terminated pursuant to
Section 10.3.2 below, the Indentures shall continue in effect after the
Effective Date for the sole purpose of allowing the
 
                                       23
<PAGE>   30
 
Indenture Trustee to make the distributions to be made on account of such
Allowed AWA Debenture Claims under the Plan and for defending any subordination
action brought under Section 3.5. AWA and NewAWA shall be required to reimburse
the Indenture Trustee solely for fees, costs and expenses (including reasonable
costs of counsel associated therewith) in connection with activities required
under this Section 10.3.1. Any fees, costs, or expenses incurred by the
Indenture Trustee for any other activities it may undertake shall be collectible
solely from the holders of AWA Debentures. Notwithstanding anything to the
contrary herein, the Indenture Trustee shall retain any and all charging liens
or similar rights provided in the Indentures for so long as it is Indenture
Trustee.
 
          10.3.2. Notwithstanding the foregoing, the Indenture Trustee may at
any time terminate any or all of the AWA Indentures and all of the Indenture
Trustee's duties and obligations and authority to act thereunder, with or
without cause, by giving fifteen (15) days written notice of termination to
NewAWA and the Distribution Agent and by turning over to the Distribution Agent
a list of record holders of Debentures under such Indenture as of the
Distribution Record Date, together with such other information and documents as
may be reasonably necessary in order to permit the Distribution Agent to make
distributions to holders of Allowed AWA Debenture Claims arising out of the AWA
Debentures issued pursuant to such Indenture. If distributions under the Plan
have not been completed at the time of termination of such Indenture, the
Distribution Agent shall thereafter act in place of such Indenture Trustee, and
all references in the Plan to the Indenture Trustee for purposes of making
distributions under the Plan with regard to such Indenture shall be deemed to
apply to such Distribution Agent. Any actions taken by the Indenture Trustee not
for a purpose authorized in the Plan shall be of no force or effect.
 
          10.3.3. For purposes of any distributions under the Plan to holders of
AWA Debenture Claims, the Indenture Trustee (or if the Indenture Trustee has
resigned in accordance with Section 10.3.2, the Distribution Agent as its
successor) shall be deemed to be the sole holder of all AWA Debenture Claims
evidenced by the AWA Debentures issued under each Indenture. Accordingly, all
distributions provided for in the Plan on account of Allowed AWA Debenture
Claims shall be distributed to the Indenture Trustee as disbursing agent or, if
the Indenture Trustee has resigned pursuant to Section 10.3.2, to the
Distribution Agent as its successor, for further distribution to individual
holders of Allowed AWA Debenture Claims pursuant to the Plan. The transfer books
of the Indenture Trustee for the Debentures shall close as of the Distribution
Record Date and no further transfers shall be recognized.
 
          10.3.4. Any provision of the Plan to the contrary notwithstanding, no
distribution under the Plan shall be required to be made by the Indenture
Trustee or the Distribution Agent to any holder of an AWA Debenture Claim until
such time as the certificate representing the AWA Debenture in respect of which
such AWA Debenture Claim is made shall have been surrendered in accordance with
Section 10.3.5. Notwithstanding any provision of this Section 10.3.4 to the
contrary, any holder of an AWA Debenture Claim based on a certificate
representing an AWA Debenture that has been lost, stolen, mutilated or destroyed
may, in lieu of surrendering such certificate as provided in this Section 10.3,
deliver to the Indenture Trustee, or if the Indenture Trustee has resigned, to
the Distribution Agent as its successor, (i) evidence satisfactory to the
Indenture Trustee or the Distribution Agent, as the case may be, of the loss,
theft, mutilation or destruction of such certificate and (ii) such security or
indemnity as may reasonably be required by the Indenture Trustee or the
Distribution Agent, as the case may be, to save the Indenture Trustee or the
Distribution Agent, as the case may be, harmless with respect thereto, and upon
providing such evidence and such security or indemnity the holder of such AWA
Debenture Claim shall, for all purposes under the Plan, be deemed to have
surrendered such certificate.
 
          10.3.5. A holder of record on the Distribution Record Date of a
certificate relating to an AWA Debenture Claim shall surrender such holder's
certificate representing such AWA Debenture Claim to the Indenture Trustee, or
if the Indenture Trustee has resigned in accordance with Section 10.3.2, to the
Distribution Agent as its successor, in accordance with written instructions
given not more than thirty (30) days after the Effective Date to such holder by
the Indenture Trustee or the Distribution Agent, as the case may be. Upon
receipt of any certificate relating to such AWA Debenture Claim, the Indenture
Trustee or the Distribution Agent shall cancel such certificate and deliver such
canceled certificate to such Person as the Distribution Agent shall designate.
 
                                       24
<PAGE>   31
 
          10.3.6. On the Final Distribution Date, all rights under the Plan of
any holder of an Allowed AWA Debenture Claim which has not surrendered its
certificate representing such AWA Debenture Claim in accordance with this
Section 10.3 shall lapse and be automatically terminated without any further
action and the Indenture Trustee or the Distribution Agent as its successor
shall at such time return to the Distribution Agent any funds or property it
then holds in respect of such unsurrendered certificate to be treated as
unclaimed property pursuant to Section 10.6 and, upon such return, the Indenture
Trustee or the Distribution Agent as its successor shall have no further
obligation in respect of such funds or property.
 
     10.4. Reserves for Distributions for Disputed Claims and Disputed Equity
Interests.
 
          10.4.1. Except as may be otherwise agreed with respect to any Disputed
Claim or Disputed Equity Interest and as approved by the Bankruptcy Court, no
distributions shall be made with respect to all or any portion of a Disputed
Claim or Disputed Equity Interest unless and until such Disputed Claim or
Disputed Equity Interest (or portion thereof) shall have become an Allowed Claim
or Equity Interest and such Allowed Claim or Equity Interest is otherwise
entitled to distributions hereunder.
 
          10.4.2. Prior to making any distribution to holders of Allowed Claims
or Equity Interests in Class 5 or Class 6.2 in accordance with Section 10.2, the
Distribution Agent shall deposit in a Reserve established separately for each
such Class an amount of NewAWA Securities and/or Cash equal to the amount of
such distribution that would have been distributed to holders of Disputed Claims
or Disputed Equity Interests in such Class if such Disputed Claims or Equity
Interests were Allowed Claims or Equity Interests in their full face amount at
the time of the calculation of such distribution. A separate Reserve shall be
established and thereafter maintained for each Class as to which any Claims or
Equity Interests remain Disputed as of the Effective Date. The Distribution
Agent shall at all times until any Disputed Claim or Disputed Equity Interest is
resolved by Final Order, retain in the Reserve all amounts that would have been
distributed to the holder of such Disputed Claim or Disputed Equity Interest had
such Claim or Equity Interest been an Allowed Claim or Equity Interest in its
full face amount on the Effective Date. Notwithstanding the foregoing, upon
motion by the Debtor or NewAWA, the Bankruptcy Court may enter a Reserve Order,
establishing a Reserve Amount to be escrowed in the Reserve for any Class which
may be less than the amount otherwise required hereunder, which amount shall
reflect the Bankruptcy Court's estimate of the level of Reserves for a
particular Class reasonably required to protect the legitimate rights and
interests of holders of Disputed Claims or Disputed Equity Interests in such
Class. In the event a Reserve Order is entered, the Distribution Agent shall
deposit or retain in the Reserve with respect to any Class subject to such order
only the Reserve Amount required by such Reserve Order. Any amount not so
deposited or retained shall be distributed to all holders of Allowed Claims or
Equity Interests in the Class for which such Reserve Amount was established as
provided for in the Plan. The date of each such distribution shall be a
Distribution Date.
 
          10.4.3. As soon as practicable after a Disputed Claim or Disputed
Equity Interest, or portion thereof, becomes an Allowed Claim or Equity
Interest, the Distribution Agent shall make a distribution to the holder of such
Allowed Claim or Equity Interest from the Reserve in the amount of (i) the
portion of the NewAWA Securities or Cash in the Reserve that should be
distributed pursuant to the terms of the Plan in view of the amount of the
Allowed Claim or Equity Interest; plus (ii) the proportional share of any
interest, earnings or dividends actually earned and received on such Reserve;
less (iii) the proportional share of any Distribution Agent Charges incurred on
account of such escrowed assets. To the extent that sufficient New AWA
Securities or Cash are not available to make the full distribution required by
the preceding sentence, in view of the then-appearing rights of the holders of
other Disputed Claims and Disputed Equity Interests, the Distribution Agent
shall make such lesser distribution as shall then be ordered by the Bankruptcy
Court. No holder of a Disputed Claim or Disputed Equity Interest shall have any
claim against the Reserve for the Class in which such Disputed Claim or Disputed
Equity Interest is included until such Disputed Claim or Disputed Equity
Interest shall become an Allowed Claim or Equity Interest. In no event shall any
holder of any Disputed Claim or Disputed Equity Interest have any recourse
against or be entitled to receive (under the Plan or otherwise) or recover from
the Debtor, NewAWA, the Distribution Agent or any Reserve, any payment (in Cash,
NewAWA Securities or other property) in the event that the Reserve therefor is
insufficient to pay an Allowed Claim or Equity Interest in full. In no event
shall the Distribution Agent, the Debtor or NewAWA have any responsibility or
liability for any loss to or of any Reserve.
 
                                       25
<PAGE>   32
 
          10.4.4. The Reserve for a Class shall be terminated when all Disputed
Claims and Disputed Equity Interests are finally resolved in such Class. All
remaining assets, if any, in the Reserve shall be distributed, first, to
holders, if any, who received less than a proportionate distribution pursuant to
order of the Bankruptcy Court under Section 10.4.3 and thereafter to all holders
of Allowed Claims or Equity Interests in the Class for which such Reserve was
established, on a pro rata basis. The date of such distribution shall be the
Final Distribution Date with regard to such Class.
 
     10.5. Fractional Interests; Odd Lots; De Minimis Distributions.
 
          10.5.1. Fractional shares or units of NewAWA Securities shall not be
issued or distributed and no Cash payments shall be made in respect thereof. All
holders of Allowed Claims or Equity Interests in such Class which would
otherwise be entitled to a fractional interest in such NewAWA Security shall be
placed on a list in descending order according to the size of the fractional
interest in the NewAWA Security to be distributed. For purposes of the preceding
sentence, Electing Unsecured Creditors and Non-Electing Unsecured Creditors
shall be placed on separate lists. In the event that two or more holders of
Allowed Claims or Equity Interests are entitled to the same fractional portion
(rounded to six decimal places) in such NewAWA Security, their relative ranking
on any such list shall be determined by lot. The fractional shares or units
which each such holder would have received will be aggregated. Then, one share
or unit, as applicable, will be distributed to each of the holders on such list
in descending order until the total amount of aggregated shares or units is
exhausted.
 
          10.5.2. In the event that any holder of an Allowed Claim or Equity
Interest would receive fewer than ten (10) shares or units of NewAWA Securities
in a distribution made under this Article 10, the Distribution Agent may instead
sell such NewAWA Securities on behalf of any or all of such holders and they
distribute to each such holder its pro rata share of the Net Proceeds of such
sale. Such sale may be either a private sale or through a securities exchange or
automated quotation system on which such NewAWA Securities are listed and absent
manifest error or intentional wrongdoing on the part of the Distribution Agent
in connection with such sale, the Net Proceeds realized from such sale shall be
conclusively determined to be reasonable. The distribution of a pro rata share
of such Net Proceeds to each such holder shall be deemed to be in full
satisfaction of the payment to be made to such holder of Allowed Claims or
Equity Interests in such distribution. These procedures are intended to result
in the affected holders receiving appropriate distributions while saving
expenses in the administration of the Debtor's estate that would be associated
with maintaining such holders as stockholders of NewAWA.
 
     10.6. Delivery of Distributions; Unclaimed Property. Distributions and
deliveries to holders of (i) Allowed General Unsecured Claims shall be made at
the addresses set forth on the proofs of claim filed by such holders (or at the
last known addresses of such holders if no proof of claim is filed or if NewAWA
has been notified of a change of address), (ii) AWA Debenture Claims shall be
made at the address contained in the records of the Indenture Trustee (or, if
the Indenture Trustee has resigned pursuant to Section 10.3.2 of the Plan, in
such records it has delivered to the Distribution Agent as its successor) and
(iii) Equity Interests shall be made to the address shown on the stock ledger of
AWA. If any holder's distribution is returned as undeliverable, no further
distributions to such holder shall be made unless and until the Distribution
Agent, NewAWA or the Indenture Trustee is notified in writing of such holder's
then-current address, at which time all missed distributions shall be made to
such holder without interest (except to the extent that such missed
distributions have become unclaimed property). Amounts in respect of
undeliverable distributions made through the Distribution Agent or through the
Indenture Trustee, shall be returned to NewAWA until such distributions are
claimed. All claims for undeliverable distributions shall be made on or before
the second (2nd) anniversary of the applicable Distribution Date, and after such
date, such undeliverable distributions shall be unclaimed property. All
unclaimed property attributable to any Claim or Equity Interest shall revert to
the Reserve, if any, then existing with regard to Claims or Equity Interests of
such Class and, if none exists, to NewAWA, and the Claim of any holder with
respect to such property shall be discharged and forever barred and shall no
longer be deemed an Allowed Claim or Equity Interest.

     10.7. Method of Payment. Payments of Cash required to be made pursuant to
the Plan shall be made by check drawn on a domestic bank or by wire transfer
from a domestic bank at the election of the Person making such payment.
 
     10.8. Payment Dates. Whenever any payment or distribution to be made under
the Plan shall be due on a day other than a Business Day, such payment or
distribution shall instead be made, without interest, on the immediately
following Business Day.
 
     10.9. Compliance with Tax Requirements. In connection with the Plan, to the
extent applicable, the Distribution Agent and the Indenture Trustee shall comply
with all tax withholding and reporting requirements imposed on it by any
governmental unit, and all distributions pursuant to the Plan shall be subject
to such withholding and reporting requirements. The Distribution Agent and
Indenture Trustee shall be authorized to take any and all actions that may be
necessary or appropriate to comply with such withholding and reporting
requirements. Notwithstanding any other provision of the Plan, (i) each Person
(including holders of Allowed Claims and Equity Interests) receiving a
distribution of Cash or NewAWA Securities pursuant to the Plan shall have sole
and exclusive responsibility for the satisfaction and payment of any tax
obligations imposed by any governmental unit, including income, withholding and
other tax obligations, on account of such distribution and (ii) at the option of
NewAWA, no distribution pursuant to the Plan shall be made to or on behalf of
such entity unless and until such entity has made arrangements satisfactory to
NewAWA for the satisfaction and payment of such tax obligations. At the option
of NewAWA, any Cash or NewAWA Securities to be distributed pursuant to the Plan
shall, pending the implementation of such arrangements, be treated as an
undeliverable distribution pursuant to Section 10.6 above.

                       PROCEDURES FOR RESOLVING DISPUTED
                           CLAIMS OR EQUITY INTERESTS
 
     11.1. Filing of Objections to Claims or Equity Interests. After the
Effective Date, objections to Claims or Equity Interests shall be made and
objections to Claims or Equity Interests made previous thereto shall be pursued
only by NewAWA and, upon leave of the Bankruptcy Court for good cause shown, the
Creditors' Committee (if it is then still in existence). Any objections made by
NewAWA or the Creditors' Committee after the Effective Date shall be served and
filed not later than 180 days after the Effective Date; provided, however, that
such period may be extended by order of the Bankruptcy Court for good cause
shown.
 
     11.2. Settlement of Objections to Claims or Equity Interests After
Effective Date. From and after the Effective Date, NewAWA may litigate to
judgment, propose settlements of, or withdraw objections to, all pending or
filed Disputed Claims or Disputed Equity Interests, and NewAWA may settle or
compromise any Disputed Claim or Disputed Equity Interest, without notice and a
hearing and without approval of the Bankruptcy Court; provided, however, notice
of any settlement or compromise involving the allowance of a General Unsecured
Claim in excess of $100,000 shall be provided to the Indenture Trustee (if the
AWA Indentures have not been previously terminated) and to the Creditors'
Committee (if still then in existence), who shall each have ten (10) days to
object to such settlement or compromise and in such case, such settlement or
compromise must be approved by the Bankruptcy Court.
 
     11.3. Payment or Distribution to Holders of Disputed Claims or Equity
Interests. Except as the Debtor or NewAWA, as applicable, may otherwise agree
with respect to any Disputed Claim or Disputed Equity Interest, no payments or
distributions shall be made with respect to any portion of a Disputed Claim or
Disputed Equity Interest unless and until all objections to such Disputed Claim
or Disputed Equity Interest have been settled or determined by a Final Order of
the Bankruptcy Court. Payments and distributions to each holder of a Disputed
Claim or Disputed Equity Interest to the extent that it ultimately becomes an
Allowed Claim or Equity Interest shall be made in accordance with Section 10.4.
A Disputed Claim or Disputed Equity Interest that is estimated for purposes of
allowance and distribution pursuant to Section 502(c) of the Bankruptcy Code and
which is estimated and Allowed at a fixed amount by Final Order of the
Bankruptcy
 
                                       27
<PAGE>   34
 
Court shall thereupon be an Allowed Claim or Equity Interest for all purposes in
the amount so estimated and Allowed.
 
     11.4. Reserves for Disputed Claims and Disputed Equity Interests.
Appropriate Reserves for Disputed Claims and Disputed Equity Interests shall be
established and maintained as provided in Section 10.4.
 
                                   ARTICLE 12
 
                            MISCELLANEOUS PROVISIONS
 
     12.1. Modification of Payment Terms. NewAWA reserves the right to modify
the treatment of any Allowed Claim in any manner adverse only to the holder of
such Claim at any time after the Effective Date upon the consent of the holder
whose Allowed Claim treatment is being adversely affected.
 
     12.2. Discharge of Debtor. The rights afforded and the treatment of Claims
and Equity Interests under the Plan shall be in exchange for and in complete
satisfaction, discharge, release and termination of all Claims of any nature
whatsoever against the Debtor or any of its assets or properties and all Equity
Interests in the Debtor; and upon the Effective Date (i) the Debtor shall be
deemed discharged and released pursuant to Section 1141(d)(1)(A) of the
Bankruptcy Code from any and all Claims, including but not limited to demands
and liabilities that arose before the Effective Date, all debts of the kind
specified in Section 502(g), 502(h) or 502(i) of the Bankruptcy Code, whether or
not (a) a proof of claim based upon such debt is filed or deemed filed under
Section 501 of the Bankruptcy Code, (b) a Claim based upon such debt is allowed
under Section 502 of the Bankruptcy Code or (c) the holder of a Claim based upon
such debt has accepted the Plan; and (ii) all rights and interests of holders of
Equity Interests in the Debtor shall be terminated pursuant to Section
1141(d)(1)(B) of the Bankruptcy Code. The Confirmation Order shall be a judicial
determination of discharge and termination of all liabilities of and all Claims
against, and all Equity Interests in, the Debtor, except as otherwise
specifically provided in the Plan. On the Effective Date, as to every discharged
debt, Claim and Equity Interest, the holder of such debt, Claim or Equity
Interest shall be permanently enjoined and precluded from asserting against
NewAWA or against its assets or properties or any transferee thereof, any other
or further Claim or Equity Interest based upon any document, instrument or act,
omission, transaction or other activity of any kind or nature that occurred
prior to the Effective Date, except as expressly set forth in the Plan or the
Confirmation Order.
 
     12.3. Termination of Subordination Rights. Except as specifically provided
elsewhere herein, on the Confirmation Date, all contractual, legal or equitable
subordination rights that a holder of a Claim or Equity Interest may have with
respect to any distribution to be made pursuant to the Plan shall be discharged
and terminated, and all actions related to the enforcement of such subordination
rights shall be permanently enjoined. Accordingly, distributions pursuant to the
Plan to holders of Allowed Claims and Equity Interests shall not be subject to
payment to a beneficiary of such terminated subordination rights, or to levy,
garnishment, attachment or other legal process by any beneficiary of such
terminated subordination rights. Pursuant to Bankruptcy Rule 9019 and in
consideration for the distribution and other benefits provided under the Plan,
the provisions of this Section 12.3 shall constitute a good faith compromise and
settlement of all claims or controversies relating to the termination of all
contractual, legal and equitable subordination rights that a holder of a Claim
or Equity Interest may have with respect to any Allowed Claim or Equity
Interest, or any distribution to be made on account of such Allowed Claim or
Allowed Equity Interest.
 
     12.4. Termination of the Creditors' and Equity Committees.
 
          12.4.1. The Creditors' Committee shall, unless theretofore terminated,
terminate on the Effective Date and shall thereafter have no further
responsibilities in respect of the Chapter 11 Case except (i) with respect to
preparation and filing of applications for compensation and reimbursement of
expenses in accordance with Section 2.2.3, (ii) with respect to any contested
matter or adversary proceeding commenced prior to the Effective Date in which
the Creditors' Committee is an indispensable litigant or any appeal of an order
in the Chapter 11 Case in which the Creditors' Committee is an indispensable
litigant and if, in each case, the Creditors' Committee's participation in such
proceeding is consistent with the orders of the Bankruptcy Court establishing
the Creditors' Committee and with Section 1103 of the Bankruptcy Code, and
 
                                       28
<PAGE>   35
 
(iii) with respect to monitoring and participating in matters and proceedings
which could give rise to General Unsecured Claims (including, without
limitation, Avoidance Litigation, rejection of executory contracts and unexpired
leases and resolution of Unsecured Deficiency Claims and Disputed General
Unsecured Claims) for a period of five months after the Effective Date, unless
such period is extended by the Bankruptcy Court for good cause shown. In
connection with such activities, the Creditors' Committee may continue the
retention of its counsel, its local counsel and its accountants and may replace
one or more of such professional advisors, if necessary, but shall not retain
additional professional advisors. NewAWA shall pay the reasonable fees and
expenses of the Creditors' Committee incurred in connection with such
activities, provided, however, that the aggregate fees related to matters and
proceedings which could give rise to General Unsecured Claims shall not exceed
an average of $75,000 per month for the first two months after the Effective
Date and an average of $50,000 per month for any subsequent month. All such fees
and expenses shall be paid only in accordance with the fee and expense
guidelines promulgated by the Debtor in the Bankruptcy Case and shall be paid by
NewAWA within thirty (30) days of receipt of invoice therefor, except in the
case of an objection to any such fees and expenses, which, if not resolved by
NewAWA and the Creditors' Committee, may be noticed by either such entity for a
hearing before the Bankruptcy Court. Notwithstanding anything to the contrary in
this Section 12.4.1, all such activities shall cease when the aggregate amount
of Disputed Claims is less than $3,000,000 or one year after the Effective Date,
whichever occurs first, except in a case where the Creditors' Committee is an
indispensable litigant as contemplated by clause (ii) above.
 
          12.4.2. The Equity Committee shall, unless theretofore terminated,
terminate on the Effective Date and shall thereafter have no further

Court to be invalid, illegal or unenforceable, then, at the option of the Debtor
or NewAWA, such provision shall not affect the validity or legality of any other
provisions of the Plan which shall remain effective.
 
     12.9. Computation of Time. In computing any period of time prescribed or
allowed by the Plan, the provisions of Bankruptcy Rule 9006(a) shall apply.

shall be governed by, and construed and enforced in accordance with, the laws of
the State of Arizona, without giving effect to the principles of conflicts of
law thereof. Notwithstanding anything to the contrary herein, the laws of

        (ii) below minus the number of shares, if any, purchased by the Equity
        Holders pursuant to the second sentence of clause (iii) below. For each
        share of Class B Common issued to it, Investor shall pay $7.467;
        provided that (A) for each share acquired by Investor pursuant to clause
        (ii) below and (B) for each share not purchased by the Equity Holders
        pursuant to clause (iii) below, Investor shall pay $8.889.
 
             (ii) Unsecured Creditors.  The Unsecured Creditors (or a trust
        created for their benefit) shall be issued 26,775,000 shares.
        Notwithstanding the foregoing, each Unsecured Creditor shall have the
        right to elect to receive cash equal to $8.889 for each share of Class B
        Common otherwise allocable to it under this clause (ii). The election of
        each such Person (the "Electing Party") must be made on or before the
        date fixed by the Bankruptcy Court for voting with respect to the Plan;
        provided, however, that in the event that such elections of all Electing
        Parties aggregate to more than $100 million, then (A) the amount of cash
        so paid shall be limited to $100 million and (B) the Electing Parties
        shall each receive proportionate amounts of cash and Class B Common in
        accordance with the Plan. Subject to the foregoing proviso, Investor
        shall increase the Investment by the amount necessary to pay all
        Electing Parties the cash amounts payable to them under this clause (ii)
        in respect of the shares of Class B Common specified in their elections
        and, upon payment of such amounts, such shares shall be issued to
        Investor without further consideration. Notwithstanding the foregoing,
        Investor's acquisition of shares of Class B Common pursuant to this
        clause (ii) shall, if permitted by applicable securities and other laws,
        be consummated immediately after the issuance of such shares to the
        Electing Parties on the Effective Date. If such shares are not so
        acquired post-

          consummation of the Plan, all shares of Class B Common acquired by
          Investor pursuant to this clause (ii) shall, for all purposes hereof,
          be deemed to be part of the Securities acquired by Investor hereunder.
 
             (iii) Equity Holders.  The Equity Holders (or a trust created for
        their benefit) shall be issued 2,250,000 shares. In addition, the Equity
        Holders shall have the right to purchase up to 1,615,179 shares
        allocable to Investor pursuant to clause (i) above at $8.889 per share.
        Such election must be made by each Equity Holder on or before the date
        fixed by the Bankruptcy Court for voting with respect to the Plan. The
        Plan shall set forth the terms and conditions on which the foregoing
        rights may be exercised.
 
             (iv) GPA.  900,000 shares shall be issued to GPA.
 
          (3) Warrants.  There shall be Warrants to purchase 10,384,615 shares
     of Class B Common at the exercise price as specified in and subject to the
     terms of Exhibit A hereto, and such Warrants shall, in accordance with the
     Plan, be issued as follows:
 
             (i) Warrants to purchase up to 2,769,231 shares of Class B Common
        shall be issued to Investor; and
 
             (ii) Warrants to purchase up to 6,230,769 shares of Class B Common
        shall be issued to the Equity Holders or a trust or trusts created for
        their benefit; and
 
             (iii) Warrants to purchase up to 1,384,615 shares of Class B Common
        shall be issued to GPA.
 
          (4) Senior Unsecured Notes.  Investor shall, in accordance with the
     Plan and subject to the terms of Exhibit B hereto, be issued $100 million
     principal amount of Notes against payment in cash of not less than 100% of
     the principal amount thereof to the Company; provided, however, that the
     Company shall have the right, exercised at any time prior to the date fixed
     by the Bankruptcy Court for voting with respect to the Plan, to increase
     the principal amount of the Notes to be so purchased by Investor to up to
     $130 million. GPA shall, in accordance with the Plan, be issued $30,525,000
     principal amount of Notes; provided, however, that GPA shall have the right
     to elect to receive cash in lieu of all or any portion of the Notes
     otherwise issuable to it under this paragraph (4), such election to be made
     on or before the date fixed by the Bankruptcy Court for voting with respect
     to the Plan.
 
     (b) Holders of the Class A Common shall have fifty votes per share. Holders
of Class B Common shall have one vote per share. Holders of Class A Common and
holders of Class B Common shall vote together as a single class except as
otherwise required by law or the provisions of this Agreement. Investor may
elect, with respect to any shares of Class B Common held by it, to suspend the
voting rights relating to such shares by giving prior written notice to the
Company, which notice shall describe such shares in reasonable detail and state
whether or not the voting suspension is permanent or temporary and, if
temporary, specify the period thereof.
 
     (c) Neither Investor nor any Affiliate of Investor or of any partner of
Investor will transfer or otherwise dispose of any Common Stock (other than to
an Affiliate of the transferor) if, after giving effect thereto and to any
concurrent transaction, the total number of shares of Class B Common
beneficially owned by the transferor is less than 200% of the total number of
shares of Class A Common beneficially owned by the transferor; provided,
however, than nothing in this paragraph (c) shall prohibit any Person from
transferring or otherwise disposing, in a single transaction or a series of
concurrent transactions, of all shares of Common Stock owned by such Person.

     Independent Director was initially designated by the Creditors' Committee
     or the Equity Committee and if, at the time of such Independent Director's
     death, resignation, removal or disability (as the case may be), the
     Creditors' Committee or the Equity Committee (as the case may be) remains
     in effect, the successor to such Independent Director shall be designated
     by the Creditors' Committee or the Equity Committee (as the case may be).

     of any and all individuals designated for such election as contemplated by
     clauses (ii), (iii), (iv) and (v) of paragraph (a) above.

     amended to reduce the rentals payable thereunder, it being understood that,
     in consideration of any such amendment and with the consent of the
     Creditors' Committee, securities of the Company may be issued to such

     claims of any kind or nature arising out of or in connection with the GPA
     Put Agreement and/or the First Refusal Agreement (other than claims for

     from all currently existing obligations to the Company in respect of shares
     of Company stock purchased by such employees pursuant to the Company's
     stock purchase plan, such release to be in consideration for the
     cancellation of such shares.

     without limitation, tax liabilities and administrative expense claims)
     required to be paid by the Company on the Effective Date or to be paid by

     the Company during the course of its bankruptcy proceedings shall not be in
     excess of the amounts reflected in Plan R-2 plus any additional allowances
     provided in Section 7 (as reduced by any repayments of the existing
     debtor-in-possession loan made on or prior to the Effective Date) and shall
     not be materially different in nature than those specified in Plan R-2
     (except with respect to administrative claims not known to the Company when
     Plan R-2 was developed); and (G) the Company shall have paid all fees and
     expenses due Investor under the Procedures Agreement;
 
          (j) since the date hereof, there shall have occurred no outbreak or
     escalation of hostilities or other international or domestic calamity,
     crisis or change in political, financial or economic conditions or other
     adverse change in the financial markets that impairs (or could reasonably
     be expected to impair) in any material respect the Company's ability to
     carry on its business in a manner consistent in all material respects with
     prior practice or impairs (or could reasonably be expected to impair) in
     any material respect Investor's ability to realize the intended benefits
     and value of this Agreement or any Related Agreement;
 
          (k) the Related Agreements, including all Alliance Agreements, to be
     executed by the Company shall have been executed by the Company on or
     before the Effective Date and, once executed, shall not have been modified
     without the consent of Investor, shall be in effect and shall not have been
     stayed;
 
          (l) the Company shall have performed in all material respects all
     obligations on its part required to be performed on or before the Effective
     Date under this Agreement, the Procedures Agreement and the Related
     Agreements and all orders of the Bankruptcy Court in respect thereof that
     are consistent with the provisions of such instruments;
 
          (m) all representations and warranties of the Company under this
     Agreement, the Procedures Agreement and the Related Agreements shall be
     true in all material respects as of the Effective Date;

     Investor (which consent shall not be unreasonably withheld), withdrawn by
     the Company or dismissed;
 
          (o) the Disclosure Statement (in the form approved by the Bankruptcy
     Court and as amended or supplemented, if applicable) shall have been true
     and correct in all material respects as of the date first mailed to
     Unsecured Parties and as of the date fixed by the Bankruptcy Court for
     voting on the Plan and such Disclosure Statement shall not contain any
     untrue statement of a material fact or omit to state any material fact
     necessary in order to make the statements made therein (taken as a whole),

     condition shall not apply to statements or other information furnished or
     provided by Investor or any of its Affiliates for use in the Disclosure
     Statement;
 
          (p) the order approving the Disclosure Statement shall have been
     entered by the Bankruptcy Court on or prior to June 30, 1994, and, once

     effect and shall not have been stayed;
 
          (q) the Plan (including all securities of the Company to be issued
     pursuant thereto and all contracts, instruments, agreements and other
     documents to be entered into in connection therewith), the Disclosure
     Statement and the Confirmation Order shall be consistent with the terms of
     this Agreement and otherwise reasonably satisfactory in form and substance
     to Investor;
 
          (r) the Confirmation Order shall have been entered by the Bankruptcy

     respect, shall be in effect and shall not have been stayed and shall not be
     subject to any appeal;
 
          (s) the Effective Date shall have occurred on or prior to the Outside
     Date unless the reason therefor shall be attributable to the breach by
     Investor or its Affiliates of any of their respective representations,
     warranties, covenants or obligations contained herein or in the Procedures
     Agreement or any Related Agreement;.
 
          (t) either pursuant to the Confirmation Order or otherwise, the
     Bankruptcy Court shall have established one or more bar dates for
     administrative expense claims pursuant to an order reasonably acceptable to
     Investor, which bar date or dates shall occur on or before dates reasonably
     acceptable to Investor; and
 
          (u) the Securities and Exchange Commission shall have declared
     effective a shelf registration statement with respect to the Securities
     issuable to Investor.
 
In the event any of the conditions set forth in clause (a)-(n), (p) or (r) is
not satisfied by the date specified in such clause (the "Deadline"), then, on
the 15th day following the then current Deadline, the Deadline shall be
automatically extended on a day-to-day basis unless the Company and Investor
otherwise agree in writing or unless Investor gives a notice of termination to
the Company pursuant to Section 20(b) of the Procedures Agreement within such
15-day period. If any Deadline is automatically extended as aforesaid, Investor
may thereafter establish a new Deadline by giving notice to the Company
specifying the new Deadline, provided that the new Deadline may not be sooner
than 30 days after the date of such notice.
 
     SECTION 9.  Conditions to Company's Obligations Relating to
Investment.  The Company's obligations to consummate or to cause the
consummation of the issuance and sale of the Securities and the other
transactions contemplated by this Agreement shall be subject to the
satisfaction, or to the effective written waiver by the Company, of the
condition described in Section 8(b) and the following additional conditions:
 
          (a) payment of the Purchase Price;
 
          (b) Investor shall have delivered to the Company appropriate closing
     documents, including, but not limited to, executed counterparts of the
     Related Agreements and certifications of officers, and opinions of legal
     counsel, all of which shall be reasonably satisfactory to the Company;
 
          (c) there shall be in effect no injunction, stay, restraining order or
     decree issued by any court of competent jurisdiction, whether foreign or
     domestic, staying the effectiveness of any of the Approvals, the Initial
     Order or the Confirmation Order, and there shall not be pending any request
     or motion for any such injunction, stay, restraining order or decree;
     provided, however, that the foregoing condition shall not apply to any such
     injunction, stay, order or decree requested, initiated or supported by the
     Company or to any such request or motion made, initiated or supported by
     the Company;
 
          (d) the Related Agreements to be executed by Investor or any of its
     partners shall have been executed by such parties on or before the
     Effective Date and, once executed, shall not have been modified without the
     consent of the Company, shall be in effect and shall not have been stayed;
 
                                      A-11
<PAGE>   52
 
          (e) Investor, Continental and Mesa shall have performed in all
     material respects all obligations on their part required to be performed on
     or before the Effective Date under this Agreement, the Procedures Agreement
     and the Related Agreements and all orders of the Bankruptcy Court in
     respect thereof that are consistent with the provisions of such
     instruments;
 
          (f) all representations and warranties of Investor, Continental and
     Mesa under this Agreement, the Procedures Agreement and the Related
     Agreements shall be true and correct in all material respects as of the
     Effective Date;
 
          (g) the Company shall be reasonably satisfied that the Alliance
     Agreements, when fully implemented, shall result in an increase to the
     Company's pretax income of not less than $40 million per year; provided,
     however, that Investor shall have no liability for any failure of the
     Company to achieve any such increase in net income except to the extent
     such failure results from a default by Investor or its partners pursuant to
     the terms of such Alliance Agreements;
 
          (h) since the date hereof, there shall have occurred (A) no outbreak
     or escalation of hostilities or other international or domestic calamity,
     crisis or change in political, financial or economic conditions or other
     adverse change in the financial markets or (B) any adverse change in the
     condition (financial or otherwise), business, assets, properties or
     prospects of Continental or Mesa, in each case that materially impairs the
     ability of either Continental or Mesa to perform its obligations under the
     Alliance Agreements or the Company's ability to realize the intended
     benefits and value of this Agreement, the Alliance Agreements (as
     contemplated by clause (g) above) or the other Related Agreements;
 
          (i) since the time of their initial filing by the Company, neither the
     Plan nor the Disclosure Statement shall have been modified in any material
     respect without the prior consent of the Company (which consent shall not
     be unreasonably withheld or delayed), withdrawn by Investor or dismissed;
 
          (j) the certificate of incorporation and bylaws of the Company shall
     contain the terms contemplated by this Agreement and shall otherwise be
     reasonably satisfactory to the Company;
 
          (k) the Plan (including all Securities to be issued pursuant thereto
     and all contracts, instruments, agreements and other documents to be
     entered into in connection therewith), the Disclosure Statement and the
     Confirmation Order shall be consistent with the terms of this Agreement and
     otherwise reasonably satisfactory in form and substance to the Company;
 
          (l) the Confirmation Order shall have been entered by the Bankruptcy
     Court in form reasonably acceptable to the Company and, once entered, shall
     not have been modified in any material respect, shall be in effect and
     shall not have been stayed and shall not be subject to any appeal; and
 
          (m) the Effective Date shall have occurred on or prior to the Outside
     Date unless the reason therefor shall be attributable to the breach by the
     Company of any of its representations, warranties, covenants or obligations
     contained herein or in the Procedures Agreement or any Related Agreement.
 
     SECTION 10.  Cooperation.  (a) The Company and Investor will cooperate in a
commercially reasonable manner, and will use their respective commercially
reasonable efforts, to consummate the transactions contemplated hereby,
including all commercially reasonable efforts to satisfy the conditions
specified in this Agreement. The Company will use commercially reasonable
efforts, and Investor will cooperate in a commercially reasonable manner in
seeking, to obtain all Approvals.
 
     (b) Notwithstanding anything in Section 8 or 9 to the contrary, if prior to
the Outside Date, the Department of Justice or any other Regulatory Authority
raises any antitrust objection to the consummation of the Investment or the
implementation of any Alliance Agreement, which objection has not been resolved
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
prejudicial to the Company or the Unsecured Parties in any material respect and
which, if
 
                                      A-12
<PAGE>   53
 
entered into or approved, would materially impair the Company's ability to
realize the reasonably anticipated benefits of such Alliance Agreements.
 
     SECTION 11.  Registration Rights Agreement.  Investor and the Company will
enter into a registration rights agreement on terms acceptable to Investor and
the Company. The registration rights agreement will reflect the understanding of
the parties with respect to their registration rights and obligations and will
provide that Investor, its partners and any assignees and transferees, shall
have the right to cause the Company to (i) include the Securities issuable to
Investor pursuant to the Plan (including any such Securities issued or issuable
in respect of the Warrants or by way of any stock dividend or stock split or in
connection with any combination of shares, merger, consolidation or similar
transaction), on customary terms, in "piggyback" underwritings and registrations
and (ii) to effect, on customary terms, one demand registration under the
Securities Act for the public offering and sale of the Securities issued to
Investor under the Plan at any time after the third anniversary of the Effective
Date.
 
     SECTION 12.  Applicable Provisions of Law and Regulations.  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.
 
          (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.
 
                                      A-13
<PAGE>   54
 
          (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:
 
          (a) The general and limited partners of Investor (other than one such
     partner which will elect to suspend the voting rights of its Securities as
     contemplated by Section 4(b)) are U.S. citizens within the meaning of
     Section 101(16) of the Federal Aviation Act of 1958, as amended.
 
          (b) Investor has, or has commitments for, sufficient funds to pay the
     Purchase Price and otherwise perform its obligations under this Agreement.
 
          (c) No written statement, memorandum, certificate, schedule or other
     written information provided (or to be provided) to the Company or any of
     its representatives by or on behalf of Investor in connection with the
     transactions contemplated by the Alliance Agreements, when viewed together
     with all other written statements and information provided to the Company
     and its representatives by or on behalf of Investor, 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.
 
     SECTION 15.  Covenants.  (a) Investor covenants (i) to support, subject to
management's recommendation, increases in employee compensation through 1995 at
least equal to those set forth in Plan R-2 and (ii) after the Effective Date, to
cause the board of directors of the Company to consider implementation of a
broad based employee incentive compensation plan and a management stock
incentive plan.
 
     (b) The Company covenants (i) to use commercially reasonable efforts to
cause the shelf registration statement referred to in Section 8(u) to remain
effective for three years following its effective date and (ii) as soon as
available, to deliver to Investor a copy of the unaudited balance sheet of the
Company as of the end of each fiscal quarter of the Company prior to the
Effective Date and the unaudited statements of income and cash flows for the
periods then ended.
 
     SECTION 16.  Certain Taxes.  The Company shall bear and pay all transfer,
stamp or other similar taxes (if any are not exempted under Section 1146 of the
Bankruptcy Code) imposed in connection with the issuance and sale of the
Securities.
 
     SECTION 17.  Administrative Expense.  All amounts owed to Investor or its
assignees by the Company under this Agreement, the Related Agreements, the
Procedures Agreement and all orders of the Bankruptcy Court in respect thereof
shall be treated as an allowed administrative expense priority claim under
Section 507(a)(1) of the Bankruptcy Code.
 
     SECTION 18.  Incorporation by Reference.  The provisions set forth in the
Procedures Agreement, including, but not limited to, the provisions regarding
confidentiality, liability indemnity and termination, are hereby incorporated by
reference and such provisions shall have the same force and effect herein as if
they were expressly set forth herein in full.

Each other party hereto covered by such filing covenants and agrees to promptly
provide to AmWest all information pertaining to such party and necessary to make
such amendments and to notify AmWest of any changes in facts or circumstances
pertaining to such party that would require any amendments under Regulation
13D-G.
 
     4.5 AmWest agrees that it shall not cause any amendment to the provisions
of the Restated Certificate of Incorporation or the Bylaws or otherwise take any
action that supersedes or materially adversely affects or impairs the rights and
obligations of the parties under this Agreement or is contrary to the provisions
of this Agreement.
 
     4.6 (a) Each certificate evidencing shares of Common Stock issued to AmWest

     THIS CERTIFICATE AND ANY INTEREST HEREIN MAY NOT BE SOLD, TRANSFERRED OR

     (b) All certificates evidencing shares of Common Stock and warrants of the
Company that have not been registered pursuant to the Securities Act of 1933, as
amended, and that are not exempt from registration under Section 1145 of the
Bankruptcy Code, shall at all times be conspicuously stamped or marked with a
legend including substantially as follows:
 
     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND THE RULES AND REGULATIONS
     THEREUNDER (THE "SECURITIES ACT") OR UNDER THE SECURITIES LAWS OF ANY

<PAGE>   67
 
the holders thereof and written request cancel all certificates evidencing such
shares of Common Stock and issue to the transferee thereof replacement
certificates that do not bear such a legend.
 
     4.7  During the term of this Agreement, AmWest shall not cause the issuance

the event of nonpayment of dividends) or (b) eliminate or reduce the number of

5. RIGHTS UPON BREACH.
 
     5.1  Each party hereto recognizes and agrees that a violation of any term,
provision, or condition of this Agreement may cause irreparable damage to the
other parties which is difficult or impossible to quantify or ascertain and that
the award of any sum of damages may not be adequate relief to such other
parties. Each party hereto therefore agrees that in the event of any breach of
this Agreement, the other party or parties shall, in addition to any remedies at
law which may be available, have the right to obtain appropriate equitable
(including, but not limited to, injunctive) relief. All remedies hereunder shall
be cumulative and not exclusive.
 
     5.2  In addition to any other remedies available at law or in equity, each
party hereto agrees that the Company shall have the right (a) to withhold
transfer, and to instruct any transfer agent for securities of the Company to
withhold transfer, of any certificates evidencing shares of Common Stock held by
AmWest or any partner or Affiliate of AmWest or transferee if the Company
reasonably believes that such transfer would not be in material compliance with
the terms and provisions of this Agreement, unless the transferee provides to
the Company an opinion of legal counsel reasonably acceptable to the Company
that such transfer will be in material compliance with the terms and provisions
hereof, and (b) to require any person requesting such transfer to provide such
information as may reasonably be requested by the Company regarding ownership of
securities, affiliations, if any, between AmWest and the transferee and such
other matters pertaining to the transfer as may be appropriate to enable the
Company to determine the compliance of the proposed transfer of securities with
the terms and provisions of this Agreement.
 
6. TERMINATION.
 
     6.1  This Agreement shall automatically terminate without any action by any
party on the day immediately preceding the Third Annual Meeting and shall not be
extended except in accordance with Section 7.3. Upon such termination, the
rights and obligations of each party hereunder shall terminate and the
provisions of this Agreement shall be of no force and effect; provided that no
such termination shall relieve any person or entity from liability for breach or
default of this Agreement prior to such termination.
 
     6.2  GPA's rights and obligations under this Agreement (other than its
obligations under Section 2.1(g)) shall terminate immediately and without notice
upon the earlier of (a) termination of this Agreement under Section 6.1, (b) the
sale or transfer by GPA of equity securities of the Company resulting in the
holding by GPA of less than two percent (2%) of the voting equity securities of
the Company (on a fully diluted basis), or (c) any occurrence, other than as
described in clause (b) above, resulting in the holding by GPA of less than two
percent (2%) of the voting equity securities of the Company (on a fully diluted
basis) if (i) the Company files a Form 10-Q under the Exchange Act, or other
written report or statement, that is delivered to GPA and a copy to the party
designated in Section 7.1, reflecting information as to the Company's total
issued and capital stock from which GPA can determine whether it holds less than
two percent (2%) of the voting equity securities of the Company (on a fully
diluted basis) and (ii) GPA continues to hold less than two percent (2%) of the
voting equity securities (on a fully diluted basis) for greater than thirty-five
(35) days after delivery of such Form 10-Q, or provision of such report or
statement to GPA. GPA acknowledges that the Company's continuing with its
existing procedures for the distribution of Form-10-Qs constitutes delivery to
GPA within the meaning of this Section 6.2.

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

                             the "New Put Agreement").
 
                             The specific number, types and delivery dates for
                             the aircraft which GPA will be entitled to deliver
                             to the Company (and which the Company will be
                             obligated to lease from GPA) in a particular year
                             during the New Put Period (as well as whether such
                             aircraft will be new or used aircraft) will be
                             determined on the basis of mutual agreement by the
                             Company and GPA, taking into account the Company's
                             fleet requirements for such year, the availability
                             to GPA for purposes of the New Put Agreement (in
                             light of applicable commercial constraints) of
                             aircraft during such year and the number of
                             aircraft theretofore delivered and thereafter
                             remaining to be delivered by GPA to the Company
                             under the New Put Agreement; provided, however,
                             that if, on or prior to the Mutual Agreement
                             Deadline (as such term is hereinafter defined) for
                             a particular year, the Company and GPA shall not
                             have mutually agreed upon the specific number,
                             types and delivery dates for the aircraft which GPA
                             will be entitled to deliver to the Company (and
                             which the Company will be obligated to lease from
                             GPA) during such year (as well as whether such
                             aircraft will be new or used aircraft), GPA will
                             have the right to put to the Company (and the
                             Company will be obligated to lease from GPA without
                             any necessity for further agreement of the Company)
                             up to the Maximum Number (as such term is
                             hereinafter defined) of aircraft for such year,
                             with (i) the specific types of such aircraft being
                             selected by GPA from among the Eligible Types (as
                             such term is hereinafter defined), (ii) such
                             aircraft being new or used aircraft as selected by
                             GPA, and (iii) the specific delivery dates for such
                             aircraft being selected by GPA, in each case, upon
                             at least 150 days' prior written notice by GPA to
                             the Company; and provided further, however, that,
                             unless GPA and the Company shall otherwise agree in
                             writing (whether by reason of mutual agreement
                             relevant to a particular year or otherwise), GPA
                             will not have the right to put to the Company more
                             than five used aircraft during the New Put Period.
                             As used herein, the term "Mutual Agreement
                             Deadline" means (i) with respect to each of 1995
                             and 1996, January 31, 1995, and (ii) with respect
                             to each ensuing year during the New Put Period,
                             January 1st of the preceding year. As used herein,
                             the term "Maximum Number" means (i) with respect to
                             1995, two, and (ii) with respect to each ensuing
                             year during the New Put Period, three. As used
                             herein, and unless GPA and the Company shall
                             otherwise agree in writing, the term "Eligible
                             Types" means, with respect to the types of aircraft
                             which GPA will be entitled to put to the Company
                             without the necessity for further agreement of the
                             Company, Boeing 737-300 aircraft, Boeing 757
                             aircraft and Airbus A320 aircraft.
 
                             The aircraft which GPA will be entitled to deliver
                             or put to the Company (and which the Company will
                             be obligated to lease from GPA) may be new or used
                             aircraft; provided, however, that unless GPA and
                             the Company shall otherwise agree in writing, GPA
                             will not have the right to deliver or put to the
                             Company more than five used aircraft during the New
                             Put Period; and provided further, however, that any
                             such aircraft which is an Airbus A320 aircraft will
                             (i) be new ex factory or like-new having no greater

                             aircraft, or have IAE V2500A-1 Engines (upgraded
                             to maximum performance) if any of the conditions
                             described in the preceding clauses (a), (b) and

                             that any such aircraft which is not an A320
                             aircraft will have such specifications (including
                             configuration and engines) as are substantially
                             the same as those of other aircraft of the same
                             type in the Company's fleet or as are otherwise

     common stock shall apply equally to all classes of common stock; provided,
     however, that in the case of dividends payable in shares of common stock,
     or options, warrants or rights to acquire shares of common stock or
     securities convertible into or exchangeable for shares of common stock, the
     shares, options, warrants, rights or securities so payable shall be payable
     in shares of, or options, warrants or rights to acquire, or securities
     convertible into or exchangeable for, Class B Common.
 
          4.1.3 Liquidation.  In the event of any voluntary or involuntary
     liquidation, dissolution or winding up of the Corporation, after payment or
     provision for payment of the debts and other liabilities of the Corporation
     and liquidation preferences, if any, of any series of Preferred Stock, the
     holders of shares of all classes of common stock shall be entitled to share
     ratably in the remaining net assets of the Corporation. Neither the merger
     or consolidation of the Corporation, nor the sale, lease or conveyance of
     all or part of its assets, shall be deemed to be a liquidation, dissolution
     or winding up of the Corporation, either voluntarily or involuntarily,
     within the meaning of this Article 4.1.3.
 
        4.1.4 Conversion.
 
             4.1.4.1 Optional Conversion of Class A Common to Class B
        Common.  Holders of Class A Common shall have the right, at their
        individual options and at any time, to convert any or all shares
 
                                        2
<PAGE>   3
 
          of Class A Common held by them to the same number of shares of Class B
          Common by delivering to the Corporation a notice of their intent to so
          convert their shares of Class A Common and surrendering the
          certificate or certificates representing such shares. The Corporation
          shall promptly issue and deliver the certificate or certificates
          evidencing the shares of Class B Common issuable upon conversion in
          accordance with the holder's instructions. Such conversion, to the
          extent permitted by law, shall be deemed to occur as of the close of
          business on the date on which the holder's notice of intent is
          received and the holder's shares of Class A Common are surrendered.
          Class B Common issued under this Article 4.1.4.1 shall be deemed duly
          authorized, validly issued, fully paid, and nonassessable.
 
             4.1.4.2 In the case of any reorganization, reclassification or
        change of shares of the Class B Common (other than a change in par value
        or from par to no par value or as a result of a subdivision or
        combination), or in the case of any consolidation of the Corporation
        with one or more corporations or a merger of the Corporation with
        another corporation, or in the case of any sale, lease or other
        disposition of all or substantially all of the assets of the
        Corporation, each holder of a share of Class A Common at the time
        outstanding shall be entitled to convert such share into the kind and
        amount of shares of stock and other securities and properties (including
        cash) receivable upon such reorganization, reclassification, change of
        shares, consolidation, merger, sale, lease or other disposition, by a
        holder of the number of shares of Class B Common into which such shares
        of Class A Common might have been converted immediately prior to such
        reorganization, reclassification, change of shares, consolidation,
        merger, sale, lease or other disposition. In the event of such a
        reorganization, reclassification, change of shares, consolidation,
        merger, sale, lease or other disposition, effective provision shall be
        made in the charter of the resulting or surviving corporation or
        otherwise for the protection of the conversion rights of the shares of
        Class A Common as nearly equivalent as practicable, into any such other
        shares of stock and other securities and property deliverable upon
        conversion of shares of Class B Common into which such Class A Common
        might have been converted immediately prior to such event.
 
             4.1.4.3 The Corporation shall at all times reserve and keep
        available out of its authorized but unissued shares of Class B Common,
        solely for the purpose of issuance upon conversion of outstanding shares
        of Class A Common, such number of shares of Class B Common as shall from
        time to time be issuable upon the conversion of all of the outstanding
        shares of Class A Common. If any shares of Class B Common required to be
        reserved for purposes of conversion hereunder (i) require registration
        with or approval of any governmental authority under any federal or
        state law before such shares of Class B Common may be issued upon
        conversion or (ii) are listed on any national or regional securities
        exchange or listing service, the Corporation shall use its commercially
        reasonable efforts and incur commercially reasonable costs to cause such
        shares to be duly registered, approved, or listed, as the case may be
        prior to the effective time of such conversion.
 
             4.1.4.4 The Corporation shall pay all documentary stamp or other
        transactional taxes attributable to the issuance or delivery of shares
        of Class B Common upon conversion of any shares of Class A Common;
        provided, however, that the Corporation shall not be required to pay any
        taxes which may be payable in respect of any transfer involved in the
        issuance or delivery of any certificate for shares of Class B Common in
        a name other than that of the registered holder of shares of Class A
        Common converted.
 
          4.2 Preferred Stock.  Except as otherwise provided in that certain
     Stockholders' Agreement for America West Airlines, Inc., dated
                    , 1994 for so long as it remains in force and effect (the
     "Stockholders' Agreement"), the Preferred Stock may be issued as a class,
     without series, or if so determined from time to time by the Board of
     Directors, either in whole or in part in one or more series, each series to
     be expressly designated by distinguishing number, letter or title prior to
     the issue of any shares thereof. The Preferred Stock, and each series
     thereof, may have such voting powers, full or limited, including the right
     to have more or less than one vote per share, or no voting powers, and such
     designations, preferences, dividend rights and relative, participating,
     optional or other special rights, qualifications, limitations and
     restrictions, if any, as shall be stated and expressed in the resolution or
 
                                        3
<PAGE>   4
 
     resolutions of the Board of Directors providing for the issuance of such
     Preferred Stock (a "Preferred Stock Designation").
 
     The Board of Directors is hereby authorized to (i) fix or alter the
dividend rights, dividend rates, dividend preferences and participations,
conversion rights, voting rights, rights and terms of redemption (including
sinking fund provisions), the price or other consideration for which shares
shall be issued, the redemption price or prices, the liquidation preferences and
any and all relative, participating, optional or other special rights,
qualifications, limitations on and restrictions of each series of the Preferred
Stock and the number of shares constituting any such series and the designation
thereof, and (ii) increase or decrease the number of shares of any series
subsequent to the issuance of shares of that series to the extent permitted by
the DGCL, but not below the number of shares of such series then outstanding. In
case the number of shares of any series shall be so decreased, the shares
constituting such decrease shall resume the status which they had prior to the
adoption of the resolution originally fixing the number of shares of such
series. Notwithstanding anything to the contrary contained in this Restated
Certificate of Incorporation or any Preferred Stock Designation, the holders of
Preferred Stock shall not be entitled to vote separately as a class with respect
to any amendment to this Restated Certificate of Incorporation to increase the
number of authorized shares of Preferred Stock.
 
     4.5 Issuance of Nonvoting Stock.  The Corporation will not issue nonvoting
equity securities to the extent prohibited by Section 1123 of the Bankruptcy
Code; provided, however that this Article 4.5 (a) will have no further force or
effect beyond that required under Section 1123 of the Bankruptcy Code, (b) will
have such force and effect, if any, only for so long as such section is in
effect and applicable to the Corporation, and (c) in all events may be amended
or eliminated in accordance with applicable law as from time to time in effect.
 
5. NUMBER AND TERM OF DIRECTORS.
 
     The Board of Directors of the Corporation shall consist of up to fifteen
(15) members, which number may be increased or decreased from time to time by
resolution duly adopted by such Board, provided that at no time shall there be
fewer than nine (9) or more than fifteen (15) members. No decrease in the number
of Directors shall have the effect of shortening the term of any incumbent
Director. Except as otherwise provided in the Stockholders' Agreement, any
Director may be removed by the stockholders of the Corporation with or without
cause pursuant to the Bylaws and applicable law.
 
     Each Director shall be elected (a) in accordance with the Bylaws and shall
serve for a term of one year or until the death, resignation or removal of such
Director, and until a successor shall have been properly elected and shall
qualify, and (b) as provided in the Stockholders' Agreement.
 
     Beginning at the annual meeting of the stockholders immediately following
the third anniversary of the effective date of this Restated Certificate of
Incorporation (the "Third Annual Meeting"), the number of Directors shall be
divided into three (3) classes, as nearly equal in number as may be, to serve in
the first instance until the first, second and third annual meetings of the
stockholders to be held after the Third Annual Meeting, respectively, and until
their successors shall have been properly elected and shall qualify; and
thereafter for three-year terms. In the case of any increase in the number of
Directors of the Corporation, the additional Directors shall be so classified
that all classes of Directors shall be increased equally as nearly as may be,
and the additional Directors shall be elected as provided herein by the
Directors or by the stockholders at an annual meeting. In case of any decrease
in the number of Directors of the Corporation, all classes of Directors shall be
decreased equally, as nearly as may be. Election of Directors shall be conducted
as provided in this Restated Certificate of Incorporation, in the Bylaws, or by
applicable law.
 
6. MANAGEMENT.
 
     The Corporation shall be managed by the Board of Directors, which shall
exercise all powers conferred under the laws of the State of Delaware. The
Bylaws shall be adopted contemporaneous with the adoption of this Restated
Certificate of Incorporation pursuant to Section 303 of the DGCL, but,
thereafter, the power to make, alter or repeal the Bylaws shall be vested in the
Board of Directors, as may be limited by the Bylaws.

7. COMPROMISE OR ARRANGEMENT WITH CREDITORS.
 
     Whenever a compromise or arrangement is proposed between this Corporation
and its creditors or any class of them and/or between this Corporation and its
stockholders or any class of them, any court of equitable jurisdiction within
the State of Delaware, may, on the application in a summary way of this
Corporation or of any creditor or stockholder thereof or on the application of
any receiver or receivers appointed for this Corporation under the provisions of
Section 291 of Title 8 of the Delaware Code or on the application of trustees in
dissolution or of any receiver or receivers appointed for this Corporation under
the provisions of Section 279 of Title 8 of the Delaware Code order a meeting of
the creditors or class of creditors, and/or of the stockholders or class of
stockholders of this Corporation, as the case may be, to be summoned in such
manner as the said court directs. If a majority in number representing
three-fourths ( 3/4) in value of the creditors or class of creditors, and/or of
the stockholders or class of stockholders of this Corporation, as the case may
be, agree to any compromise or arrangement and to any reorganization of this
Corporation as consequence of such compromise or arrangement, the said
compromise or arrangement and the said reorganization shall, if sanctioned by
the Court to which the application has been made, be binding on all the
creditors or class of creditors, and/or on all the stockholders, of this
Corporation, as the case may be and also on this Corporation.
 
8. VACANCIES ON THE BOARD OF DIRECTORS.
 
     Except as otherwise provided in the Stockholders' Agreement, in case any
vacancy shall occur on the Board of Directors because of death, resignation,
retirement, disqualification, removal, an increase in the authorized number of
Directors or any other cause, the Board of Directors shall have the sole and
exclusive authority to, in accordance with the Bylaws, elect a Director to fill
such vacancy.
 
9. SPECIAL MEETINGS OF STOCKHOLDERS.
 
     Special meetings of the stockholders of the Corporation, for any purpose or
purposes, unless otherwise prescribed herein or by statute, may be called by the
Chairman of the Board and shall be called by the Secretary at the written
request, or by resolution adopted by the affirmative vote, of a majority of the
Board of Directors. Stockholders of the Corporation shall not be entitled to
request a special meeting of the Stockholders.
 
10. NO STOCKHOLDER ACTION BY WRITTEN CONSENT.
 
     All action by holders of the Corporation's outstanding voting securities
shall be taken at an annual or special meeting of the stockholders following
notice (or by written consent as provided below) as provided by law or in the
Bylaws. Stockholders of the Corporation shall have the power to act by means of
written consent only in the removal of directors in accordance with the
Stockholders' Agreement.
 
11. NOMINATIONS FOR ELECTION OF DIRECTORS.
 
     Except as may be otherwise provided in the Stockholders' Agreement, no
person shall be elected to the Board of Directors of this Corporation at an
annual meeting of the stockholders, or at a special meeting called for that
purpose, unless a written nomination of such person to the Board of Directors
(i) by a stockholder of the Corporation shall be received by the Corporation in
accordance with the Bylaws or (ii) is made by or at the direction of the Board
of Directors.
 
12. LIMITATION OF DIRECTOR LIABILITY; INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     12.1 Limitation of Liability.  A person who is or was a Director of the
Corporation shall not be personally liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the Director's duty of loyalty to the
Corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the DGCL; or (iv) for any transaction from which the Director
derived an improper personal benefit. If the DGCL is amended to authorize
corporate action further eliminating or limiting the personal liability of
directors, then the liability of the Directors of the Corporation
 
                                        5
<PAGE>   6
 
shall be eliminated or limited to the fullest extent permitted by the DGCL, as
so amended. The elimination and limitation of liability provided herein shall
continue after a Director has ceased to occupy such position as to acts or
omissions occurring during such Director's term or terms of office, and no
amendment or repeal of this Article 12.1 shall apply to or have any effect on
the liability or alleged liability of any Director of the Corporation for or
with respect to any acts or omissions of such Director occurring prior to such
amendment or repeal.
 
     12.2 Indemnification.  The Corporation shall indemnify, to the fullest
extent permitted by applicable law and pursuant to the Bylaws, each person who
is or was a Director or officer of the Corporation, and may indemnify each
employee and agent of the Corporation and all other persons whom the Corporation
is authorized to indemnify under the provisions of the DGCL.
 
13. FOREIGN OWNERSHIP OF VOTING STOCK.
 
     At no time shall more than twenty five percent (25%) of the voting interest
of the Corporation be owned or controlled by persons who are not "Citizens of
the United States" (as such term is defined in Section 101 of the Federal
Aviation Act of 1958, as amended, (Title 49, United States Code), or as the same
may be from time to time amended) ("Non-Citizens"). In the event that
Non-Citizens shall own (beneficially or of record) or have voting control over
any shares of common stock of the Corporation, the voting rights of such persons
shall be subject to automatic suspension to the extent required to ensure that
the Corporation is in compliance with applicable provisions of law and
regulations relating to ownership or control of a U.S. carrier. The Bylaws shall
contain provisions to implement this Article 13.0, including, without
limitation, provisions restricting or prohibiting transfer of shares of voting
stock to Non-Citizens and provisions restricting or removing voting rights as to
shares of voting stock owned or controlled by Non-Citizens. Any determination as
to ownership, control or citizenship made by the Board of Directors shall be
conclusive and binding as between the Corporation and any stockholder for
purposes of this Article 13.0.

     or her address as it appears on the records of the Corporation. Personal
     delivery of any such notice to any officer of a corporation or association
     or to any member of a partnership shall constitute delivery of such notice

          (c) Notice of any meeting of stockholders need not be given to any
     stockholder if waived by such stockholder in writing, whether before or
     after such meeting is held, or if such stockholder shall sign the minutes

procedures set forth in this Section 3.06.
 
          (a) For a proposal to be properly brought before an annual meeting by
     a stockholder, the stockholder must have given timely notice thereof in
     writing to the Secretary. To be timely, a stockholder's notice must be
     delivered to, or mailed and received, at the principal executive offices of
     the Corporation not less than sixty (60) days nor more than ninety (90)
     days prior to the scheduled annual meeting, regardless of any
     postponements, deferrals or adjournments of that meeting to a later date;
     provided, however, that if less than seventy (70) days notice or prior
     public disclosure of the date of the scheduled annual meeting is given or
     made, notice by the stockholder to be timely must be so delivered or

     stockholder in such proposal.

place, unless otherwise provided by these Restated Bylaws, notice need not be
given of the adjourned meeting if the time and place thereof are announced at
the meeting at which the adjournment is taken. At the adjourned meeting the
stockholders may transact any business which might have been transacted at the
original meeting. If an adjournment is for more than thirty (30) days or if
after an adjournment a new record date is fixed for the adjourned meeting, a
notice of the adjourned meeting shall be given to each stockholder entitled to
vote at the meeting.
 
     3.08 Quorum and Adjournment.  Except as otherwise provided by law, by the
Restated Certificate of Incorporation of the Corporation or by these Restated
Bylaws, the presence, in person or by proxy, of the holders of a majority of the
aggregate voting power of the stock issued and outstanding, entitled to vote
thereat, and the voting rights of which are not suspended, shall be requisite
and shall constitute a quorum for the transaction of business at all meetings of
stockholders. If, however, such majority shall not be present or represented at
any meeting of stockholders, the stockholders present, although less than a
quorum, shall have the power to adjourn the meeting.
 
     3.09 Majority Vote Required.  When a quorum is present at any meeting of
stockholders, the affirmative vote of the majority of the aggregate voting power
of the shares present in person or represented by proxy at the meeting and
entitled to vote on the subject matter shall constitute the act of the
stockholders, unless by express provision of law, the Restated Certificate of
Incorporation or these Restated Bylaws a different vote is required, in which
case such express provision shall govern and control.
 
                                        2
<PAGE>   6
 
     3.10 Manner of Voting.  At each meeting of stockholders, each stockholder
having the right to vote, and whose voting rights have not been suspended shall
be entitled to vote in person or by proxy. Proxies need not be filed with the
Secretary of the Corporation until the meeting is called to order, but shall be
filed before being voted. Each stockholder shall be entitled to vote each share
of stock having voting power registered in his name on the books of the
Corporation on the record date fixed, as provided in Section 6.04 of these
Restated Bylaws, for the determination of stockholders entitled to vote at such
meeting. All elections of directors shall be by written ballot.
 
     3.11 Proxies.  (a) At any meeting of stockholders, any stockholder may be
represented and vote by proxy or proxies appointed by a written form of proxy.
In the event that any form of proxy shall designate two or more persons to act
as proxies, a majority of such persons present at the meeting or, if only one
shall be present, then that one shall have and may exercise all of the powers
conferred by the form of proxy upon all of the persons so designated unless the
form of proxy shall otherwise provide.
 
          (b) The Board of Directors may, in advance of any annual or special
     meeting of the stockholders, prescribe additional regulations concerning
     the manner of execution and filing of proxies and the validation of the
     same, which are intended to be voted at any such meeting.

person presiding over any meeting of the stockholders shall have the power and
duty to determine whether a nomination or any other business proposed to be
brought before the meeting was made in accordance with the procedures set forth
in this Article 3 or Section 4.03 and, if any proposed nomination or business is
not in compliance with such provisions, to declare that such defective proposal
or nomination shall be disregarded.
 
     3.14 Inspections of Elections.  The Board of Directors by resolution shall
appoint one or more inspectors of election (which may include individuals who
serve the Corporation in other capacities including, without limitation, as
officers, employees, agents or representatives of the Corporation) to act at any
meeting of the stockholders and make a written report thereof. Such appointments
shall be made in accordance with, and each inspector shall have the duties
prescribed by, Section 231 of the General Corporation Law of the State of
Delaware (the "DCGL").
 
4. DIRECTORS.
 
     4.01 Powers.  The Board of Directors shall exercise all of the power of the
Corporation except such as are by law, or by the Restated Certificate of

Corporation shall consist of up to fifteen (15) members, which number may be
increased or decreased from time to time by resolution duly adopted by such

dated             among the Corporation and others, for so long as it remains in
force and effect (as supplemented and amended from time to time, herein
"Stockholders' Agreement"), shall prescribe the exact number of directors and
their method of election, removal and replacement. No decrease in the number of
Directors shall have the effect of shortening the term of any incumbent
Director.
 
          (b) Subject to and at such time as provided in the Restated
     Certificate of Incorporation, the number of Directors shall be divided into
     three (3) classes, as nearly equal in number as may be, to serve staggered
     three-year terms on the Board of Directors. In the case of any increase in
     the number of Directors of the Corporation, the additional Directors shall
     be so classified that all classes of Directors shall be increased equally
     as nearly as may be, and the additional Directors shall be elected as
     provided herein by the Directors or by the stockholders at an annual
     meeting. In case of any decrease in the number of Directors of the
     Corporation, all classes of Directors shall be decreased equally, as nearly
     as

     law.

Agreement, no person shall be elected to the Board of Directors of this
Corporation at an annual meeting of the stockholders, or at a special meeting
called for that purpose, unless a written nomination of such person to the Board
of Directors (i) by a stockholder of the Corporation who is entitled to vote at
such meeting shall be received by the Secretary of the Corporation at least
ninety (90) days prior to such meeting or (ii) is made by or at the direction of
the Board of Directors.
 
     4.04 Resignations.  Any Director may resign at any time by giving written
notice to the Board of Directors or the Secretary. Such resignation shall take
effect at the date of receipt of such notice or at any later time specified
therein. Acceptance of such resignation shall not be necessary to make it
effective.
 
     4.05 Removal.  Except as otherwise provided in the Stockholders' Agreement,
at any special meeting of the stockholders duly called as provided herein, any
Director may, by a vote of the holders of stock representing a majority of the
voting power of all the shares of stock issued and outstanding and entitled to
vote thereat, be removed from office with or without cause, and the successor of
the Director so removed may be elected at such meeting. Stockholders shall have
the right to act by written consent in the removal of directors in accordance
with the Stockholders' Agreement. In the absence or such an election, any
vacancy may be filled as provided in Section 4.06.
 
     4.06 Vacancies.  (a) Except as otherwise provided in the Stockholders'
Agreement, in case any vacancy shall occur on the Board of Directors because of
death, resignation, retirement, disqualification, removal, an increase in the
authorized number of Directors or any other cause, the Board of Directors may,
at any meeting, by resolution adopted by the affirmative vote of a majority of
the Directors then in office, though less than a quorum, elect a Director to
fill such vacancy.
 
          (b) If, as a result of a disaster or emergency (as determined in good
     faith by the then remaining Directors), it becomes impossible to ascertain
     whether or not vacancies exist on the Board of Directors, and a person is
     or persons are elected by Directors, who in good faith believe themselves
     to be a majority of the remaining Directors, to fill a vacancy or vacancies
     that said remaining Directors in good faith believe exists, then the acts
     of such person or persons who are so elected as Directors shall be valid
     and binding upon the corporation and the stockholders, although it may
     subsequently develop that at the time of the election (i) there was in fact
     no vacancy or vacancies existing on the Board of Directors, or (ii) the
     Directors who so elected such person or persons did not in fact constitute
     a majority of the remaining Directors.

Directors are elected, for the purpose of organization, election of officers,
and consideration of such other business as the Board considers relevant to the
management of the Corporation.

shall be held at such times and places, within or without the State of Delaware,
as shall be designated by the Chairman of the Board on not less than three (3)
days' notice (specifying the time and place of the meeting and the agenda

quorum is present shall be the act of the Board of Directors or such committee,
unless by express provision of law, of the Restated Certificate of Incorporation
or these Restated Bylaws, a different vote is required, in which case such
express provision shall govern and control. In the absence of a quorum, a

committee thereof, may participate in any meeting of the Board of Directors or
such committee by means of conference telephone or similar communications

person at such meeting.
 
     (b) Any action required or permitted to be taken at any meeting of the
Board of Directors or any committee thereof may be taken without a meeting if
all members of the Board of Directors or such committee, as the case may be,
consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the Board of Directors or such committee.
 
     4.14 Compensation.  (a) The Board of Directors, by a resolution or
resolutions may fix, and from time to time change, the compensation of
Directors.
 
     (b) Each Director shall be entitled to reimbursement from the Corporation

     any meeting thereof.
 
          5.06 Salaries.  The salaries of all officers of the Corporation shall
     be fixed by the Board of Directors from time to time, and no officer shall
     be prevented from receiving such salary by reason of the fact that he is

     entitling the holders thereof to purchase from the Corporation any shares
     of any class or classes or any other securities of the Corporation for such

     authorized but unissued stock of the Corporation the requisite number of
     shares for issuance upon the exercise of such warrants, rights or options.
     Such warrants, rights or options shall be evidenced by such instrument or
     instruments as shall be approved by the Board of Directors. The terms upon

7. LIMITATIONS OF OWNERSHIP BY NON-CITIZENS.
 
     7.01 Definitions.  (a) "Act" shall mean the Federal Aviation Act of 1958,
as amended (Title 49 United States Code) or as the same may be from time to time
amended.
 
          (b) "Beneficial Ownership," "Beneficially Owned" or "Owned
     Beneficially" refers to beneficial ownership as defined in Rule 13d-3
     (without regard to the 60-day provision in paragraph (d)(1)(i) thereof)
     under the Securities Exchange Act of 1934, as amended.
 
          (c) "Foreign Stock Record" shall have the meaning set forth Section
     7.03.
 
          (d) "Non-Citizen" shall mean any person or entity who is not a
     "Citizen of the United States" as defined in Section 101 of the Act,
     including any agent, trustee or representative of a Non-Citizen.
 
                                        9
<PAGE>   13
 
          (e) "Own or Control" or "Owned or Controlled" shall mean (i) ownership
     of record, (ii) beneficial ownership or (iii) the power to direct, by
     agreement, agency or in any other manner, the voting of Stock. Any
     determination by the Board of Directors as to whether Stock is Owned or
     Controlled by a Non-Citizen shall be final.
 
          (f) "Permitted Percentage" shall mean twenty five percent (25%) of the
     voting power of the Stock.
 
          (g) "Stock" shall mean the outstanding capital stock of the
     corporation entitled to vote; provided, however, that for the purpose of
     determining the voting power of Stock that shall at any time constitute the
     Permitted Percentage, the voting power of Stock outstanding shall not be
     adjusted downward solely because shares of Stock may not be entitled to
     vote by reason of any provision of this Article 7.
 
     7.02 Policy.  It is the policy of the Corporation that, consistent with the
requirements of Section 101 of the Act, Non-Citizens shall not Own or Control
more than the Permitted Percentage and, if Non-Citizens nonetheless at any time
Own or Control more than the Permitted Percentage, the voting rights of the
Stock in excess of the Permitted Percentage shall be automatically suspended in
accordance with Sections 7.03 and 7.04 below.
 
     7.03 Foreign Stock Record.  The Corporation or any transfer agent
designated by it shall maintain a separate stock record (the "Foreign Stock
Record") in which shall be registered Stock known to the corporation to be Owned
or Controlled by Non-Citizens. The Foreign Stock Record shall include (i) the
name and nationality of each such Non-Citizen, (ii) the number of shares of
Stock Owned or controlled by such Non-Citizen and (iii) the date of registration
of such shares in the Foreign Stock Record. In no event shall shares in excess
of the Permitted Percentage be entered on the Foreign Stock Record. In the event
that the Corporation shall determine that stock registered on the Foreign Stock
Record exceeds the Permitted Percentage, sufficient shares shall be removed from
the Foreign Stock Record so that the number of shares entered therein does not
exceed the Permitted Percentage. Stock shall be removed from the Foreign Stock
Record in reverse chronological order based upon the date of registration
therein.
 
     7.04 Suspension of Voting Rights.  If at any time the number of shares of
Stock known to the Corporation to be Owned or Controlled by Non-Citizens exceeds
the Permitted Percentage, the voting rights of Stock Owned or Controlled by
Non-Citizens and not registered on the Foreign Stock Record at the time of any
vote or action of the stockholders of the Corporation shall, without further
action by the Corporation, be suspended. Such suspension of voting rights shall
automatically terminate upon the earlier of the (i) transfer of such shares to a
person or entity who is not a Non-Citizen, or (ii) registration of such shares
on the Foreign Stock Record, subject to the final sentence of Section 7.03.
 
     7.05 Beneficial Ownership Inquiry.  (a) The Corporation may by notice in
writing (which may be included in the form of proxy or ballot distributed to
stockholders in connection with the annual meeting or any special meeting of the
stockholders of the Corporation, or otherwise) require a person that is a holder
of record of Stock or that the Corporation knows to have, or has reasonable
cause to believe has, Beneficial Ownership of Stock to certify in such manner as
the Corporation shall deem appropriate (including by way of execution of any
form of proxy or ballot of such person) that, to the knowledge of such person:
 
             (i) all Stock as to which such person has record ownership or
        Beneficial Ownership is owned and controlled only by Citizens of the
        United States; or
 
             (ii) the number and class or series of Stock owned of record or
        Beneficially Owned by such person that is owned or controlled by
        Non-Citizens is as set forth in such certificate.
 
          (b) With respect to any Stock identified in response to clause (a)(ii)
     above, the Corporation may require such person to provide such further
     information as the Corporation may reasonably require in order to implement
     the provisions of this Article 7.
 
          (c) For purposes of applying the provisions of this Article 7 with
     respect to any Stock, in the event of the failure of any person to provide
     the certificate or other information to which the Corporation is entitled
     pursuant to this Section 7.05, the Corporation shall presume that the Stock
     in question in owned or controlled by Non-Citizens.

          (b) At least ten (10) days before each meeting of stockholders, the
     officer in charge of the stock ledger of the Corporation shall prepare a
     complete list of the stockholders entitled to vote at the meeting, arranged
     in alphabetical order and showing the address of each stockholder and the
     number of shares registered in the name of each stockholder. Such list
     shall be open to the examination of any stockholder, for any purpose
     germane to the meeting, during ordinary business hours, for a period of at
     least ten (10) days prior to the meeting, either at a place within the city
     where the meeting is to be held, which place shall be specified in the
     notice of the meeting, or, if not specified, at the place where the meeting
     is to be held. The list shall also be produced and kept at the time and
     place of the meeting during the whole time thereof, and may be inspected by
     any stockholder who is present.
 
          (c) The Board of Directors shall determine from time to time whether
     and, if allowed, when and under what conditions and regulations the
     accounts and books of the Corporation (except such as may be by law
     specifically open to inspection or as otherwise provided by these Restated
     Bylaws) or any of them shall be open to the inspection of the stockholders
     and the stockholders' rights in respect thereof.
 
     8.02 Indemnification of Directors, Officers, Employees and Agents.  (a) The
Corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of the Corporation) by reason of the fact that such
person is or was a Director or officer of the Corporation, or is or was serving
at the request of the Corporation as a director, officer, employee, agent or
fiduciary of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise, against expenses, including attorneys' fees,
judgments, fines and amounts paid or owed in settlement actually and reasonably
paid or incurred by him or her or rendered or levied against him or her in
connection with such action, suit or proceeding if he acted in good faith and in
a manner he or she reasonably believed to be in or not opposed to the best
interests of the Corporation; and with respect to any criminal action or
proceeding, had no reasonable cause to believe his or her conduct was unlawful.
The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent
shall not, in itself, create a presumption that the person did not act in good
faith and in a manner which he or she reasonably believed to be in or not
opposed to the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his or her
conduct was unlawful.
 
          (b) The Corporation shall indemnify any person who was or is a party
     or is threatened to be made a party to any threatened, pending or completed
     action or suit by or in the right of the Corporation to procure a judgment
     in its favor by reason of the fact that such person is or was a Director or
     officer of the Corporation, or is or was serving at the request of the
     Corporation as a director, officer, employee, agent or fiduciary of another
     corporation, partnership, joint venture, trust, employee benefit plan or
     other enterprise, against expenses, including attorneys' fees, actually and
     reasonably paid or incurred by him or her in connection with the defense or
     settlement of such action or suit if he or she acted in good faith and in a
     manner he reasonably believed to be in or not opposed to the best interests
     of the Corporation; provided, however, that no indemnification shall be
     made in respect to any claim, issue or matter as to which such person shall
     have been adjudged to be liable to the Corporation unless and only to the
     extent that the Court of Chancery or the court in which such action or suit
     was brought shall determine upon application that, despite the adjudication
     of liability but in view of all circumstances of the case, such person is
     fairly and reasonably entitled to indemnity for such expenses which the
     court shall deem proper.
 
          (c) The Corporation shall, at the discretion of the Board of
     Directors, indemnify all employees and agents of the Corporation (other
     than Directors and officers) to the extent that Directors and officers
     shall be indemnified pursuant to subsections (a) and (b).

<PAGE>   15
 
          (d) To the extent that a person who may be entitled to indemnification
     by the Corporation under this section is or has been successful on the
     merits or otherwise in defense of any action, suit or proceeding referred
     to in subsections (a) and (b), or in defense of any claim, issue or matter
     therein, he shall be indemnified against expenses, including attorney's
     fees, actually and reasonably paid or incurred by him in connection
     therewith.
 
          (e) Any indemnification under subsections (a), (b), or (c) shall be
     made by the Corporation only as authorized in the specific case upon a
     determination that indemnification of the Director, officer, employee or
     agent is proper in the circumstances because he or she has met the
     applicable standard of conduct set forth in subsection (a) or (b). Such
     determination shall be made (i) by the Board of Directors by a majority
     vote of a quorum consisting of Directors who were not parties to such
     action, suit or proceeding, (ii) if such a quorum is not obtainable or,
     even if obtainable, a quorum of disinterested Directors so directs, by
     independent legal counsel in a written opinion, (iii) by the stockholders,
     or (iv) in any case in which applicable law makes court approval a
     prerequisite to indemnification, by the court in which such action, suit or
     proceeding was brought or another court of competent jurisdiction.
 
          (f) Expenses, including attorneys' fees, incurred by an officer or
     Director in defending a civil, criminal, administrative, or investigative
     action, suit or proceeding shall be paid by the Corporation in advance of
     the final disposition of such action, suit or proceeding upon receipt of an
     undertaking by or on behalf of the Director or officer to repay such amount
     if it shall ultimately be determined that he or she is not entitled to be
     indemnified by the Corporation as authorized in this section. Such
     expenses, including attorneys' fees, incurred by other employees and agents
     shall be so paid upon terms and conditions, if any, as the Board of
     Directors deems appropriate.
 
          (g) The indemnification and advancement of expenses provided by, or
     granted pursuant to, the other subsections of this section shall not be
     deemed exclusive of any other rights to which those seeking indemnification
     or advancement of expenses may be entitled under any bylaw, agreement, vote
     of the stockholders or disinterested directors or otherwise, both as to
     action in an official capacity and as to action in another capacity while
     holding such office.
 
          (h) The provisions of this section shall continue as to a person who
     has ceased to be a Director, officer, employee or agent and shall inure to
     the benefit of the estate, executors, administrators, spouse, heirs,
     legatees or devisees of a person entitled to indemnification hereunder and
     the term "person," where used in the section shall include the estate,
     executors, administrators, spouse, heirs, legatees or devisees of such
     person.
 
          (i) For the purposes of this Section 8.02, (i) "employee benefit plan"
     and "fiduciary" shall be deemed to include, but not be limited to, the
     meanings set forth, respectively, in Sections 3(3) and 21(A) of the
     Employee Retirement Income Security Act of 1974, as amended, and references
     to the judgments, fines and amounts paid or owed in settlement or rendered
     or levied shall be deemed to encompass and include excise taxes required to
     be paid pursuant to a applicable law in respect of any transaction
     involving an employee benefit plan, (ii) references to the Corporation
     shall be deemed to include any predecessor corporation and any constituent
     corporation absorbed in a merger, consolidation or other reorganization of
     or by the Corporation which, if its separate existence had continued, would
     have had power and authority to indemnify its directors, officers,
     employees, agents or fiduciaries so that any person who was a director,
     officer, employee, agent or fiduciary of such predecessor or constituent
     corporation, or served at the request of such predecessor or constituent
     corporation as a director, officer, employee, agent or fiduciary of another
     corporation, partnership, joint venture, trust, employee benefit plan or
     other enterprise, shall stand in the same position under the provisions of
     this Section 8.02 with respect to the Corporation as such person would have
     with respect to such predecessor or constituent corporation if its separate
     existence had continued, and (iii) all other terms shall be deemed to have
     the meanings for such terms as set forth in Section 145 of the DGCL.
 
     8.03 Dividends.  (a) Dividends may be declared at the discretion of the
Board of Directors at any meeting thereof.

          (b) Dividends may be paid to stockholders in cash or, when the
     Directors shall so determine, in stock. A Director shall be fully protected
     in relying in good faith upon the books of account of the Corporation or
     statements prepared by any of its officers as to the value and amount of
     the assets, liabilities or net profits of the Corporation, or any other
     facts pertinent to the existence and amount of surplus or other funds from
     which dividends might properly be declared.
 
          (c) Before payment of any dividend or any distribution of profits,
     there may be set aside out of the said surplus of the Corporation such sum
     or sums as the Board of Directors from time to time, in its discretion
     thinks proper as a reserve fund to meet contingencies, or for equalizing
     dividends, or for such other purpose as the Board of Directors shall think
     conducive to the interests of the Corporation and the Board of Directors
     may abolish any such reserve in the manner in which it was created.
 
     8.04 Execution of Deeds, Contracts, and Other Agreements and
Instruments.  Subject to the specific directions of the Board of Directors, all
deeds, mortgages and bonds entered into by the Corporation and all other written

President, or such other person or persons as may be authorized by any such
officer.
 
     8.05 Checks.  All checks, drafts, acceptances, notes and other orders,

endorsed on behalf of the Corporation by such officer or officers or by such
agent or agents as the Board of Directors may from time to time designate.

        as a whole by the Depository to the nominee of the Depository or by a
        nominee of the Depository to the Depository or another nominee of the
        Depository or by the Depository or any such nominee to a successor
        Depository or a nominee of such successor Depository.
 
     Each Depository must, at the time of its designation and at all times while
it serves as Depository, be a clearing agency registered under the Exchange Act
and any other applicable statute or regulation.
 
     SECTION 2.3  Certificate of Authentication.  Only such Securities as shall
bear thereon a certificate of authentication substantially in the form set forth
in Exhibit A hereto, executed (subject to Section 8.13) by the Trustee by the
manual signature of one of its authorized officers, shall be entitled to the
benefits of this Indenture or be valid or obligatory for any purpose. The
execution of such certificate by the Trustee upon any Security executed by the
Company shall be conclusive evidence that the Security so authenticated has been
duly authenticated and delivered hereunder and that the Holder of such Security
is entitled to the benefits of this Indenture.
 
     SECTION 2.4  Payments of Interest.  The Securities shall bear interest from
the date of authentication, and such interest shall be payable on the dates set
forth therein.
 
     The person in whose name any Security is registered at the close of
business on any record date applicable to such Security with respect to any
Interest Payment Date for such Security shall be entitled to receive the
interest, if any, payable on such Interest Payment Date notwithstanding any
transfer or exchange of such Security subsequent to the record date and prior to
such Interest Payment Date, except if and to the extent the Company shall
default in the payment of the interest due on such Interest Payment Date, in
which case such defaulted interest shall be paid to the persons in whose names
Outstanding Securities are registered at the close of business on a subsequent
record date (which shall be not less then five Business Days prior to the date
of payment of such defaulted interest) established by notice given by mail by or
on behalf of the Company to the Holders of Securities not less than 15 days
preceding such subsequent record date. The term "record date" as used with
respect to any Interest Payment Date (except a date for payment of defaulted
interest) for the Securities shall mean the date specified as such in the terms
of the Securities.
 
     Subject to the foregoing provisions of this Section 2.4, each Security
delivered under this Indenture upon transfer of or in exchange for or in lieu of
any other Security shall carry the rights to interest accrued and unpaid, and to
accrue, which were carried by such other Security.
 
     SECTION 2.5  Registration, Transfer and Exchange.  The Company will keep at
each office or agency to be maintained for the purpose as provided in Section
4.2 a register or registers in which, subject to such reasonable regulations as
it may prescribe, it will provide for the registration of Securities and the
registration of transfer of Securities. Such register shall be in written form
in the English language or in any other form capable of being converted into
such form within a reasonable time. At all reasonable times such register or
registers shall be open for inspection by the Trustee.
 
     Upon due presentation for registration of transfer of any Security at any
such office or agency to be maintained for the purpose as provided in Section
4.2, the Company shall execute and the Trustee shall authenticate and deliver in
the name of the transferee or transferees a new Security or Securities.
 
     At the option of the Holder thereof, Securities (other than a Global
Security, except as set forth below) may be exchanged for a Security or
Securities having authorized denominations in an equal aggregate principal
amount, upon surrender of such Securities to be exchanged at the agency of the
Company that shall
 
                                        9
<PAGE>   16
 
be maintained for such purpose in accordance with Section 4.2 and upon payment,
if the Company shall so require, of the amounts hereinafter provided.
 
     All Securities presented for registration of transfer, exchange, redemption
or payment shall (if so required by the Company or the Trustee) be duly endorsed
by, or be accompanied by a written instrument or instruments of transfer, in
form satisfactory to the Company and the Trustee and duly executed by the Holder
or his attorney duly authorized in writing.
 
     The Company may require payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection with any exchange or
registration of transfer of Securities. No service charge shall be made for any
such transaction.
 
     The Company shall not be required to exchange or register a transfer of (a)
any Securities for a period of 15 days next preceding the first mailing of
notice of redemption of Securities to be redeemed or (b) any Securities
selected, called or being called for redemption, in whole or in part, except, in
the case of any Security to be redeemed in part, the portion thereof not so to
be redeemed.
 
     Notwithstanding any other provision of this Section 2.5, unless and until
it is exchanged in whole or in part for Securities in non-global form, a Global
Security representing all or a portion of the Securities may not be transferred
except as a whole by the Depository to a nominee of such Depository or by a
nominee of such Depository to such Depository or another nominee of such
Depository or by such Depository or any such nominee to a successor Depository
or a nominee of such successor Depository.
 
     If at any time the Depository for any Securities represented by one or more
Global Securities notifies the Company that it is unwilling or unable to
continue as Depository for such Securities or if at any time the Depository for
such Securities shall no longer be eligible under Section 2.2, the Company shall
appoint a successor Depository eligible under Section 2.2 with respect to such
Securities. If a successor Depository eligible under Section 2.2 for such
Securities is not appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such ineligibility, the Company will
execute, and the Trustee, upon receipt of an Officer's Certificate of the
Company for the authentication and delivery of Securities in non-global form,
will authenticate and deliver Securities in non-global form in exchange for such
Global Security or Securities.
 
     The Company may at any time and in its sole discretion determine that the
Securities issued in the form of one or more Global Securities shall no longer
be represented by a Global Security or Securities. In such event the Company
will execute, and the Trustee, upon receipt of an Company order for the
authentication and delivery of Securities in non-global form, will authenticate
and deliver, Securities in non-global form in exchange for such Global Security
or Securities.
 
     Any person having a beneficial interest in a Global Security may upon
request exchange such beneficial interest for Securities in non-global form.
Upon receipt by the Trustee of written instructions (or such other form of
instructions as is customary for the Depository) from the Depository or its
nominee on behalf of any person having a beneficial interest in a Global
Security and upon receipt by the Trustee of a written order or such other form
of instructions as is customary for the Depository or the person designated by
the Depository as having such a beneficial interest containing registration
instructions, then the Trustee will cause, in accordance with the standing
instructions and procedures existing between the Depository and the Trustee, the
aggregate principal amount of the Global Security to be reduced and following
such reduction, the Company will execute and upon receipt of an authentication
order in the form of an Officers' Certificate, the Trustee will authenticate and
deliver Securities in non-global form.
 
     Securities in non-global form issued in exchange for a beneficial interest
in a Global Security pursuant to this Section 2.5 shall be registered in such
names and in such authorized denominations as the Depository for such Global
Security, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Trustee or an agent of the Company or the Trustee.
The Trustee or such agent shall deliver such Securities to or as directed by the
Person in whose names such Securities are so registered.
 
                                       10
<PAGE>   17
 
     The Securities executed by the Company, and authenticated and delivered by
the Trustee, upon any transfer or exchange contemplated by this Section 2.5
shall be dated the date of their authentication, shall be in authorized
denominations, shall be in like aggregate principal amount and have the same
Stated Maturity date and interest rate as, and bear interest from the most
recent date to which interest has been paid on (or if no interest has been paid,
from the date of), the Securities surrendered upon such transfer or exchange (or
as the portion of any Global Security being exchanged for Securities in
non-global form, as the case may be), and shall bear a number of other
distinguishing symbol not appearing on any Security contemporaneously
Outstanding.
 
     All Securities issued upon any transfer or exchange of Securities shall be
valid obligations of the Company, evidencing the same debt, and entitled to the
same benefits under this Indenture, as the Securities surrendered upon such
transfer or exchange.
 
     SECTION 2.6  Mutilated, Defaced, Destroyed, Lost and Stolen Securities.  In
case any temporary or definitive Security shall become mutilated, defaced or be
destroyed, lost or stolen, the Company in its discretion may execute, and upon
the written request of any officer of the Company, the Trustee shall
authenticate and deliver a new Security of the same Stated Maturity date
appearing on any Security, interest rate as, bearing interest from the most
recent date to which interest has been paid on (or if no interest has been paid,
from the date of) the mutilated or defaced Security, or the Security so
destroyed, lost or stolen, and bearing a number or other distinguishing symbol
not contemporaneously Outstanding, in exchange and substitution for the
mutilated or defaced Security, or in lieu of or in substitution for the Security
so destroyed, lost or stolen. In every case the applicant for a substitute
Security shall furnish to the Company and to the Trustee and any agent of the
Company or the Trustee such security or indemnity as may be required by them to
indemnify and defend and to save each of them harmless and, in every case of
destruction, loss or theft, evidence to their satisfaction of the destruction,
loss or theft of such Security and of the ownership thereof and in the case of
mutilation or defacement, shall surrender the Security to the Trustee or such
agent.
 
     Upon the issuance of any substitute Security, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses (including the fees
and expenses of the Trustee or its agent) connected therewith. In case any
Security that has matured or is about to mature or has been called for
redemption in full shall become mutilated or defaced or be destroyed, lost or
stolen, the Company may, instead of issuing a substitute Security, pay or
authorize the payment of the same (without surrender thereof except in the case
of a mutilated or defaced Security), if the applicant for such payment shall
furnish to the Company and to the Trustee and any agent of the Company or the
Trustee such security or indemnity as any of them may require to save each of
them harmless, and, in every case of destruction, loss or theft, the applicant
shall also furnish to the Company and the Trustee and any agent of the Company
or the Trustee evidence to their satisfaction of the destruction, loss or theft
of such Security and of the ownership thereof.
 
     Every substitute Security issued pursuant to the provisions of this Section
2.6 by virtue of the fact that any such Security is destroyed, lost or stolen
shall constitute an additional contractual obligation of the Company whether or
not the destroyed, lost or stolen Security shall be at any time enforceable by
anyone and shall be entitled to all the benefits of (but shall be subject to all
the limitations of rights set forth in) this Indenture equally and
proportionately with any and all other Securities duly authenticated and
delivered hereunder. All Securities shall be held and owned upon the express
condition that, to the extent permitted by law, the foregoing provisions are
exclusive with respect to the replacement or payment of mutilated, defaced or
destroyed, lost or stolen Securities and shall preclude any and all other rights
or remedies notwithstanding any law or statute existing or hereafter enacted to
the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.
 
     SECTION 2.7  Cancellation of Securities; Destruction Thereof.
 
          (a) All Securities surrendered for payment, redemption, registration
     of transfer or exchange, if surrendered to the Company or any agent of the
     Company or any agent of the Trustee, shall be delivered to the Trustee for
     cancellation and, upon receipt thereof by the Trustee, shall be cancelled
     by it; and no Securities shall be issued in lieu thereof except as
     expressly permitted by any of the provisions of this
 
                                       11
<PAGE>   18
 
     Indenture. The Trustee shall destroy cancelled Securities held by it and
     deliver a certificate of destruction to the Company. If the Company or any
     agent of the Company shall acquire any of the Securities, such acquisition
     shall not operate as a redemption or satisfaction of the indebtedness
     represented by such Securities unless and until the same are delivered to
     the Trustee for cancellation.
 
          (b) At such time as all beneficial interests in a Global Security have
     either been exchanged for Securities in non-global form, redeemed,
     repurchased or cancelled, such Global Security shall be returned to and
     cancelled by the Trustee. At any time prior to such cancellation, if any
     beneficial interest in a Global Security is exchanged for Securities in
     non-global form, redeemed, repurchased or cancelled, the principal amount
     of Securities represented by such Global Security shall be reduced and an
     endorsement shall be made on such Global Security by the Trustee to reflect
     such reduction.
 
     SECTION 2.8  Temporary Securities.  Until definitive Securities are ready
for delivery, the Company may prepare and the Trustee shall authenticate
temporary Securities. Temporary Securities shall be substantially in the form of
definitive Securities but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee, upon receipt of a written order signed by two
Officers of the Company, shall authenticate definitive Securities in exchange
for temporary Securities. Until such exchange, temporary Securities shall be
entitled to the same rights, benefits and privileges as definitive Securities.
 
     SECTION 2.9  Currency and Manner of Payments in Respect of
Securities.  Payment of the principal of and premium (if any) and interest on,
any Security will be made in U.S. Legal Tender.
 
     SECTION 2.10  CUSIP Number.  A "CUSIP" number will be printed on the
Securities, and the Trustee shall use the CUSIP number in notices of redemption,
purchase or exchange as a convenience to Holders, provided that any such notice
may state that no representation is made as to the correctness or accuracy of
the CUSIP number printed in the notice or on the Securities and that reliance
may be placed only on the other identification numbers printed on the
Securities. The Company will promptly notify the Trustee of any change in the
CUSIP number.
 
                                 ARTICLE THREE
 
                                  REDEMPTIONS
 
     SECTION 3.1  Notices to Trustee.  If the Company elects to redeem
Securities pursuant to Section 3.7 it shall furnish to the Trustee, at least 10
but not more than 15 days before notice of any redemption is to be mailed to
Holders (or such shorter time as may be satisfactory to the Trustee), an
Officers, Certificate stating that the Company has elected to redeem Securities
pursuant to Section 3.7, the date notice of redemption is to be mailed to
Holders, the Redemption Date, the aggregate principal amount of Securities to be
redeemed, the Redemption Price for such Securities and the amount of accrued and
unpaid interest on such Securities as of the Redemption Date. If the Trustee is
not the registrar for the Securities, the Company shall, concurrently with
delivery of its notice to the Trustee of a redemption, cause the registrar for
the Securities to deliver to the Trustee a certificate (upon which the Trustee
may rely) setting forth the name of, and the aggregate principal amount of
Securities held by each Holder. The Company will also provide the Trustee with
any additional information that the Trustee reasonably requests in connection
with any redemption.
 
     SECTION 3.2  Selection of Securities to be Redeemed.  If less than all
outstanding Securities are to be redeemed, the Company shall select the
outstanding Securities to be redeemed or accepted for payment in compliance with
the requirements of the principal national securities exchange, if any, on which
the Securities are listed or, if the Securities are not listed on a securities
exchange, on a pro rata basis, by lot or by any other method that the Trustee
deems fair and appropriate. If the Company elects to mail notice of a redemption
to Holders, the Trustee shall, at least 5 days prior to the date notice of
redemption is to be mailed, (i) select the Securities to be redeemed from
Securities Outstanding not previously called for redemption, and (ii) promptly
notify the Company of the names of each Holder of Securities selected for
redemption, the principal amount of Securities held by each such Holder and the
principal amount of such Holder's Securities that are to be
 
                                       12
<PAGE>   19
 
redeemed. The Trustee shall select for redemption Securities or portions of
Securities in principal amounts of $1,000 or integral multiples of $1,000;
except that if all of the Securities of a Holder are selected for redemption,
the aggregate principal amount of the Securities held by such Holder, even if
not a multiple of $1,000, may be redeemed. Except as provided in the preceding
sentence, provisions of this Indenture that apply to Securities called for
redemption also apply to portions of Securities called for redemption.
 
     SECTION 3.3  Notice of Redemption.
 
          (a) At least 30 days but not more than 60 days before any Redemption
     Date, the Company shall mail by first class mail to each such Holder's
     registered address a notice of redemption to each Holder of Securities or
     portions thereof that are to be redeemed. With respect to any redemption of
     Securities, the notice shall identify the Securities or portions thereof to
     be redeemed and shall state: (1) the Redemption Date; (2) the Redemption
     Price for the Securities and the amount of unpaid and accrued interest on
     such Securities as of the date of redemption; (3) if any Security is being
     redeemed in part, the portion of the principal amount of such Security to
     be redeemed and that, after the Redemption Date, upon surrender of such
     Security, a new Security or Securities in principal amount equal to the
     unredeemed portion will be delivered; (4) the name and address of the
     Paying Agent; (5) that Securities called for redemption must be surrendered
     to the Paying Agent to collect the Redemption Price for, and any accrued
     and unpaid interest on, such Securities; (6) that, unless the Company
     defaults in making such redemption payment, interest on Securities called
     for redemption ceases to accrue on and after the Redemption Date and the
     only remaining right of the Holders of such Securities is to receive
     payment of the Redemption Price upon surrender to the Paying Agent of the
     Securities redeemed; and (7) if fewer than all the Securities are to be
     redeemed, the identification of the particular Securities (or portions
     thereof) to be redeemed, as well as the aggregate principal amount of
     Securities to be redeemed and the aggregate principal amount of Securities
     to be outstanding after such partial redemption.
 
          (b) At the Company's request, the Trustee shall (at the Company's
     expense) give the notice of any redemption to Holders; provided, however,
     that the Company shall deliver to the Trustee, at least 10 days prior to
     the date that notice of the redemption is to be mailed to Holders, an
     Officers' Certificate that (i) requests the Trustee to give notice of the
     redemption to Holders, (ii) sets forth the information to be provided to
     Holders in the notice of redemption, as set forth in the preceding
     paragraph, and (iii) sets forth the aggregate principal amount of
     Securities to be redeemed and the amount of accrued and unpaid interest
     thereon as of the redemption date. If the Trustee is not the registrar for
     the Securities, the Company shall, concurrently with any such request,
     cause the registrar for the Securities to deliver to the Trustee a
     certificate (upon which the Trustee may rely) setting forth the name of,
     the address of, and the aggregate principal amount of Securities held by,
     each Holder; provided further that any such Officers' Certificate may be
     delivered to the Trustee on a date later than permitted under this Section
     3.3(b) if such later date is acceptable to the Trustee.
 
     SECTION 3.4  Effect of Notice of Redemption.  Once notice of redemption is
mailed to the Holders, Securities called for redemption shall become due and
payable on the Redemption Date at the Redemption Price. Upon surrender to the
Trustee or the Paying Agent, the Securities called for redemption shall be paid
at the Redemption Price.
 
     SECTION 3.5  Deposit of Redemption Price.
 
          (a) On or prior to any Redemption Date, the Company shall deposit with
     the Paying Agent money sufficient to pay the Redemption Price of, and
     accrued interest on, all Securities to be redeemed on that date. After any
     Redemption Date, the Trustee or the Paying Agent shall promptly return to
     the Company any money that the Company deposited with the Trustee or the
     Paying Agent in excess of the amounts necessary to pay the Redemption Price
     of, and accrued interest on, all Securities to be redeemed.
 
          (b) If the Company complies with the preceding paragraph, unless the
     Company defaults in the payment of such Redemption Price, interest on the
     Securities to be redeemed will cease to accrue on such Securities on the
     applicable Redemption Date, whether or not such Securities are presented
     for payment. If a Security is redeemed on or after an interest record date
     but on or prior to the related
 
                                       13
<PAGE>   20
 
     Interest Payment Date, then any accrued and unpaid interest shall be paid
     to the Person in whose name such Security was registered at the close of
     business on such record date. If any Security called for redemption shall
     not be so paid upon surrender for redemption because of the failure of the
     Company to comply with the preceding paragraph, interest will be paid on
     the unpaid principal and interest from the redemption date until such
     principal and interest is paid, at the rate of interest provided in the
     Securities and Section 4.1.
 
     SECTION 3.6  Securities Redeemed in Part.  Upon surrender of a Security
that is redeemed in part, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder at the Company's expense a new Security
equal in principal amount to the unredeemed portion of the Security surrendered.
If a Global Security is so surrendered, such new Security so issued shall be a
new Global Security.
 
     SECTION 3.7  Optional Redemption.  The Company, at its option on notice to
the Holders as provided herein, may redeem the Securities:
 
          (a) prior to             , 1997
 
             (i) at any time in whole but not in part, at a Redemption Price
        equal to 105% of the aggregate principal amount of the Securities then
        Outstanding, plus accrued and unpaid interest thereon to the Redemption
        Date; or
 
             (ii) from time to time in part from the Net Offering Proceeds
        received by the Company prior to             , 1997 from one or more
        Public Offering Sales at a Redemption Price equal to 105% of the
        aggregate principal amount of the Securities so redeemed, plus accrued
        and unpaid interest thereon to the Redemption Date; and
 
          (b) on and after             , 1997, at any time in whole or from time
     to time in part, at a Redemption Price equal to the applicable percentage
     of the aggregate principal amount of the Securities so to be redeemed, set
     forth below, plus accrued and unpaid interest thereon to the Redemption
     Date.

                            COVENANTS OF THE COMPANY
 
     SECTION 4.1  Payment of Principal and Interest.  The Company covenants and
agrees that it will duly and punctually pay or cause to be paid the principal
of, premium (if any) and interest on, each of the Securities at the place or
places, at the respective times and in the manner provided in such Securities
and in this Indenture. To the extent lawful, the Company shall pay interest on
overdue principal, premium and interest at a rate equal to the then applicable
interest rate on the Securities, compounded semi-annually.
 
     SECTION 4.2  Offices for Payments, etc.  So long as any Securities are
authorized for issuance pursuant to this Indenture or are outstanding hereunder,
the Company will maintain in the Borough of Manhattan, the City of New York, an
office or agency where the Securities may be presented for payment and for
exchange and registration of transfer as in this Indenture provided. The Company
will give prompt written notice to the Trustee of any change in the location of
such office or agency. Until the Company shall furnish to the Trustee a
different address therefor, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office of the Trustee as specified
in Section 12.4 hereof.
 
     The Company may also from time to time designate one or more other offices
or agencies where the Securities may be presented or surrendered for any or all
such purposes and may from time to time rescind
 
                                       14
<PAGE>   21
 
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in the Borough of Manhattan, the City of New York, for such purposes.
The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.
 
     SECTION 4.3  Appointment to Fill a Vacancy in Office of Trustee.  The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 8.9, a Trustee so that there
shall at all times be a Trustee with respect to the Securities.
 
     SECTION 4.4  Paying Agents.  Whenever the Company shall appoint a Paying
Agent other than the Trustee with respect to the Securities, it will cause such
Paying Agent to execute and deliver to the Trustee an instrument in which such
agent shall agree with the Trustee, subject to the provisions of this Section
4.4,
 
          (a) that it will hold all sums received by it as such agent for the
     payment of the principal of, premium (if any) and interest on the
     Securities (whether such sums have been paid to it by the Company or any
     other obligor on the Securities) in trust for the benefit of the Holders of
     the Securities or of the Trustee,
 
          (b) that it will give the Trustee notice of any failure by the Company
     (or by any other obligor on the Securities) to make any payment of the
     principal of, premium (if any) or interest on the Securities when the same
     shall be due and payable, and
 
          (c) that it will pay any such sums so held in trust by it to the
     Trustee upon the Trustee's written request, at any time during the
     continuance of the failure referred to in clause (b) above.
 
     The Company will, on or prior to each due date of the principal of, premium
(if any) or interest on the Securities, deposit with the Paying Agent a sum
sufficient to pay such principal, premium or interest so becoming due, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the
Trustee of any failure to take such action.
 
     If the Company shall act as its own Paying Agent with respect to the
Securities it will, on or before each due date of the principal of, premium (if
any) or interest on the Securities set aside, segregate and hold in trust for

satisfaction and discharge with respect to the Securities or for any other
reason, pay or cause to be paid to the Trustee all sums held in trust with
respect to the Securities by the Company or any Paying Agent hereunder, as
required by this Section, such sums to be held by the Trustee upon the trusts
herein contained.

     all such Defaults or Events of Default of which each such Officer may have
     knowledge and what action the Company has taken or proposes to take with
     respect thereto), and (B) no event has occurred and remains in existence by
     reason of which payments on account of the principal of, premium (if any)

     of the event and what action the Company is taking or proposes to take with
     respect thereto. The Company will, so long as any of the Securities are
     outstanding, deliver to the Trustee, promptly after any Officer of the
     Company becomes aware of (i) any Default or Event of Default, or (ii) any
     default or event of default under any issue of Indebtedness that could
     result in an Event of Default under Section 7.1, an Officers' Certificate
     specifying such Default, Event of Default or default and what action the
     Company is taking or proposes to take with respect thereto.
 
          (b) If the Company is subject to the requirements of Section 13 or
     15(d) of the Exchange Act, the Company shall file with the Commission all
     quarterly and annual reports and such other information, documents or other
     reports (or copies of such portions of any of the foregoing as the
     Commission may by rules and regulations prescribe) required to be filed
     pursuant to such provisions of the Exchange Act. The Company shall file
     with the Trustee, within 5 days after it files the same with the
     Commission, copies of the quarterly and annual reports and such other

     that it files with the Commission as contemplated by this Section 4.5(b).
     The Company shall also comply with the other provisions of Section 314(a)

     Commission, all information and financial statements, including any notes
     thereto and with respect to annual reports, an auditors' report by an
     accounting firm of established national reputation, and a "Management's

     include in annual and quarterly reports, information, documents or other
     reports, including, without limitation, reports on Forms 10-K, 10-Q and

existence of each Subsidiary of the Company and the rights (charter and
statutory) and franchises of the Company and any Subsidiary of the Company;
provided, that the Company shall not be required to preserve any such corporate,
partnership or other existence of any Subsidiary or any such right or franchise,
if the Board of Directors of the Company shall determine in the exercise of its
business judgment that the preservation thereof is no longer desirable in the
conduct of the business of the Company or any Subsidiary and that abandonment of
any such right or franchise shall have no material adverse effect on the Company
and its Subsidiaries taken as a whole, or the Holders.
 
     SECTION 4.7  Payment of Taxes and Other Claims.  The Company will pay or
discharge or cause to be paid or discharged, before the same shall become

property of the Company or any Subsidiary, and (2) all lawful claims for labor,
materials and supplies that, if unpaid, might by law become a lien upon the
property of the Company, or any Subsidiary; provided, however, that the Company
shall not be required to pay or discharge or cause to be paid or discharged any

which is being contested in good faith by appropriate proceedings and with
respect to which an adequate reserve has been established by the Company to the

judgment of the Company may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times;
provided, however, that nothing in this Section shall prevent the Company or any
Subsidiary from discontinuing the operation and maintenance of any of such
properties if such discontinuance is, in the good faith judgment of the Company
or such Subsidiary, as the case may be, desirable in the conduct of its
respective business and not disadvantageous in any material respect to the
Holders.
 
                                       16

     SECTION 4.9  Maintenance of Insurance.  The Company will insure and keep
insured, and will cause each Subsidiary to insure and keep insured, with
reputable insurance companies, such of their respective properties, to such an

     each Public Offering Sale so consummated at a time when, immediately prior
     to such consummation, the Company shall have cash and Cash Equivalents, not
     subject to any restriction on disposition, of at least $100,000,000, make
     an offer to apply a portion of the Net Offering Proceeds thereof equal to
     the lesser of (x) 50% of such Net Offering Proceeds and (y) the excess, if
     any, of (i) $20,000,000 over (ii) the amount of any Net Offering Proceeds
     of any prior Public Offering Sale received prior to                , 1997,
     and applied to purchase Securities pursuant to a prior Net Proceeds Offer
     pursuant to this Section 4.11), to purchase Securities on a pro rata basis
     from all Holders (a "Net Proceeds Offer") at a purchase price equal to 104%
     of the principal amount of the Securities so purchased, plus accrued and
     unpaid interest to the date of purchase. Any Net Proceeds Offer shall
     remain open from the time of mailing until 5 days (or such shorter period
     as may be required under applicable law) before the Net Proceeds Purchase
     Date.
 
          (b) Notice of a Net Proceeds Offer pursuant to this Section 4.11 shall
     be mailed, by first class mail, by the Trustee on behalf of the Company not
     more than 60 days after the consummation of the relevant Public Offering

     tender Securities pursuant to the Net Proceeds Offer and shall state the
     following terms:
 
             (i) that the Net Proceeds Offer is being made pursuant to this
        Section 4.11 and that all Securities tendered will be accepted for
        purchase; provided, however, that if the aggregate purchase price of
        Securities tendered in a Net Proceeds Offer (including accrued interest
        at the expiration of such offer) exceeds the aggregate amount of the Net
        Offering Proceeds required to be applied in such Net Proceeds Offer, the
        Company shall select the Securities to be purchased on a pro rata basis
        (with such adjustments as may be deemed appropriate by the Company so
        that only Securities in denominations of $1,000 or integral multiples
        thereof shall be purchased);
 
             (ii) the purchase price (including the amount of accrued interest)
        and the purchase date (which shall be a Business Day no earlier than 30
        days nor later than 60 days from the date such notice is mailed) (the
        "Net Proceeds Purchase Date");
 
             (iii) that any security not tendered will continue to accrue
        interest if interest is then accruing;
 
             (iv) that, unless the Company defaults in making payment therefor,
        any Security accepted for purchase pursuant to the Net Proceeds Offer
        shall cease to accrue interest on the Net Proceeds Purchase Date;
 
             (v) that Holders electing to have a Security purchased pursuant to
        a Net Proceeds Offer will be required to surrender the Security, with
        the form entitled "Option of Holder to Elect Purchase" on the reverse of
        the Security completed, to the Paying Agent at the address specified in
        the notice prior to the close of business on the Business Day prior to
        the Net Proceeds Purchase Date;
 
                                       17
<PAGE>   24
 
             (vi) that each Holder will be entitled to withdraw its election (in
        whole but not in part) if the Paying Agent receives, not later than the
        close of business on the third Business Day immediately preceding the
        Net Proceeds Purchase Date, a telegram, telex, facsimile transmission or
        letter setting forth the name of the Holder, the principal amount of the
        Securities the Holder delivered for purchase and a statement that such
        Holder is withdrawing its election to have such Securities purchased;
        and
 
             (vii) that Holders whose Securities were purchased only in part
        will be issued new Securities equal in aggregate principal amount to the
        unpurchased portion of the Securities surrendered.
 
     On the Net Proceeds Purchase Date, the Company shall: (i) accept for
purchase on a pro rata basis Securities or portions thereof tendered pursuant to
the Net Proceeds Offer; (ii) deposit with the Paying Agent money sufficient to
pay the purchase price of all Securities or portions thereof so accepted; and
(ii) deliver, or cause to be delivered, to the Trustee all Securities or
portions thereof so accepted together with an Officers' Certificate specifying
the Securities or portions thereof accepted for purchase by the Company. The
Paying Agent shall promptly mail to the Holders of Securities so accepted
payment in an amount equal to the purchase price, and the Company shall execute
and the Trustee shall promptly authenticate and mail to each of such Holders a
new Security equal in principal amount to any unpurchased portion of the
Security surrendered; provided that each Security purchased and each new
Security delivered shall be in a principal amount of $1,000 or an integral
multiple thereof. The Company will publicly announce the results of the Net
Proceeds Offer as soon as practicable after the Net Proceeds Purchase Date. For
purposes of this Section 4.11, the Trustee shall act as the Paying Agent.

        Capital Stock (other than Redeemable Stock)) to holders of Capital Stock
        of the Company;
 
             (ii) purchase, redeem or otherwise acquire or retire for value
        (other than through the issuance solely of Capital Stock (other than
        Redeemable Stock) or options, warrants or other giths to purchase
        Capital Stock (other than Redeemable Stock)) any Capital Stock or
        warrants, rights (other than exchangeable or convertible Indebtedness of

        in substance or legal defeasance), or otherwise acquire or retire for
        value (other than through the issuance solely of Capital Stock (other
        than Redeemable Stock) or warrants, rights or options to acquire Capital
        Stock (other than Redeemable Stock)) (collectively, a "prepayment"),
        directly or indirectly (including by way of amendment of the terms of
        any Indebtedness in connection with any retirement or acquisition of
        such Indebtedness), other than at any scheduled maturity thereof or by
        any scheduled repayment or scheduled sinking fund payment, any
        Indebtedness which is subordinated in right of payment to the
 
                                       18
<PAGE>   25
 
          Securities or which matures after the maturity date of the Securities
          (except out of the proceeds of Refinancing Indebtedness);
 
     if, at the time of such transaction described in clause (i), (ii) or (iii)
     (such transactions being hereinafter collectively referred to as
     "Restricted Payments") or after giving effect thereto, either (x) a Default
     or an Event of Default shall have occurred and be continuing or (y) the
     aggregate amount expended by the Company and its Subsidiaries for all
     Restricted Payments (the amount of any Restricted Payment if other than
     cash to be the fair market value of the property included in such payment
     as determined in good faith by the Board of Directors as evidenced by a
     Board Resolution) from and after the Closing Date shall exceed the sum of
     (A) 50% (or, if the Securities at the time of the proposed Restricted
     Payment are rated Investment Grade by both S&P and Moody's, 75%) of the
     aggregate Adjusted Consolidated Net Income (or if such Adjusted
     Consolidated Net Income is a loss, minus 100% of such loss) of the Company
     and its Subsidiaries for the period from the first day of the first quarter
     ended subsequent to the Closing Date and through the last day of the most
     recently completed quarter immediately preceding the quarter in which the
     Restricted Payment occurs, calculated on a cumulative basis as if such
     period were a single accounting period; (B) the aggregate net proceeds
     received by the Company after the Closing Date (including the fair market
     value of non-cash proceeds as determined in good faith by the Board of
     Directors as evidenced by a Board Resolution) from any Person other than a
     Subsidiary, as a result of the issuance of (or contribution to capital on)
     Capital Stock of the Company (other than any Redeemable Stock) or warrants,
     rights or options to acquire Capital Stock (other than any Redeemable
     Stock); (C) the aggregate net proceeds received by the Company after the
     Closing Date from any Person other than a Subsidiary as a result of the
     issuance of Capital Stock (other than Redeemable Stock) upon conversion or
     exchange of Indebtedness or upon exercise of options, warrants or other
     rights to acquire such Capital Stock and (D) $25,000,000. For purposes of
     any calculation that is required to be made in respect of, or after, the
     declaration of a dividend by the Company, such dividend shall be deemed to
     be paid at the date of declaration and shall be included in determining the
     aggregate amount of Restricted Payments.
 
          For the purposes of this Section 4.13, the net proceeds from the
     issuance of shares of Capital Stock of the Company upon conversion of debt
     securities shall be deemed to be an amount equal to the net book value of
     such debt securities (plus the additional amount required to be paid upon
     such conversion, if any), less any cash payment on account of fractional
     shares; the "net book value" of a security shall be the net amount received
     by the Company on the issuance of such security, as adjusted on the books
     of the Company to the date of conversion.
 
          (b) Notwithstanding the foregoing, if no Default or Event of Default
     shall have occurred or be continuing at the time or as a result thereof,
     the provisions of this Section 4.13 shall not prohibit (i) the payment of
     any dividend in respect of the Company's Capital Stock within 60 days after
     the date of declaration thereof, if at such date of declaration such
     payment complied with the provisions hereof; (ii) the purchase, redemption
     or other acquisition or retirement for value of any shares of the Company's
     Capital Stock or the prepayment of any indebtedness of the Company which is
     subordinated in right of payment to the Securities or which matures after
     the maturity date of the Securities by any exchange for, or out of and to
     the extent the Company has received cash proceeds from the substantially
     concurrent sale or issuance (other than to a Subsidiary) of, shares of
     Capital Stock (other than any Redeemable Stock) of the Company or warrants,
     rights or options to acquire Capital Stock (other than any Redeemable
     Stock); or (iii) the purchase or redemption of shares of Capital Stock of
     the Company (including options on any such shares or related stock
     appreciation rights or similar securities) held by officers or employees of
     the Company or its Subsidiaries (or their estates or beneficiaries under
     their estates) upon death, disability, retirement, termination of
     employment of any such Person pursuant to the terms of any Plan or any
     other agreement under which such shares of stock or related rights were
     issued; provided that the aggregate amount of such purchases or redemptions
     of such Capital Stock shall not exceed $3,000,000 in any one fiscal year of
     the Company. For purposes of determining the aggregate amount of Restricted
     Payments permitted under clause (y) of Section 4.13(a), all amounts
     expended pursuant to clauses (i) (to the extent deemed to have been paid
     and already included in determining the
 
                                       19
<PAGE>   26
 
     aggregate amount of Restricted Payments pursuant to clause (y) of Section
     4.13(a)), (ii) and (iii) of this paragraph shall be excluded.
 
          Prior to making any Restricted Payment under this Section, the Company
     shall deliver to the Trustee an Officers' Certificate setting forth the
     computation by which the amount available for Restricted Payments was
     determined. The Trustee shall have no duty or responsibility to determine
     the accuracy or correctness of this computation or that the provisions of
     this Section have been satisfied and shall be fully protected in relying on
     such Officers' Certificate.
 
     SECTION 4.14  Limitation on Transactions with Affiliates.
 
          (a) Neither the Company nor any Subsidiary of the Company shall,
     directly or indirectly (i) sell, lease, transfer or otherwise dispose of
     any of its properties or assets, or issue securities to, (ii) purchase any
     property, assets or securities from, (iii) make any Investment in, or (iv)
     enter into or suffer to exist any contract or agreement with or for the
     benefit of, an Affiliate or holder of 5% or more of any class of Capital
     Stock (and any Affiliate of such holder) of the Company (an "Affiliate
     Transaction"), other than (x) Affiliate Transactions permitted under
     Section 4.14(b) and (y) Affiliate Transactions (including lease
     transactions) which are on fair and reasonable terms no less favorable to
     the Company or such Subsidiary, as the case may be, than those as might
     reasonably have been obtainable at such time from an unaffiliated party;
     provided that if an Affiliate Transaction or series of related Affiliate
     Transactions involves or has a value in excess of $1,000,000 and less than
     or equal to $5,000,000, the Company or such Subsidiary, as the case may be,
     shall not enter into such Affiliate Transaction or series of related
     Affiliate Transactions unless a majority of the disinterested members of
     the Board of Directors of the Company or such Subsidiary or an Independent
     Financial Advisor shall reasonably and in good faith determine that such
     Affiliate Transaction is fair to the Company or such Subsidiary, as the
     case may be, or is on terms no less favorable to the Company or such
     Subsidiary, as the case may be, than those as might reasonably have been
     obtainable at such time from an unaffiliated party. In addition, neither
     the Company nor any Subsidiary shall enter into an Affiliate Transaction or
     series of related Affiliate Transactions involving or having a value of
     more than $5,000,000 unless the Company or such Subsidiary, as the case may
     be, has received an opinion from an Independent Financial Advisor to the
     effect that the financial terms of such Affiliate Transaction are fair to
     the Company or such Subsidiary or are at least as favorable as might
     reasonably have been obtained at such time from an unaffiliated party.
 
          (b) The provisions of Section 4.14(a) shall not apply to (i) any
     agreement as in effect as of the Closing Date, or any amendment thereto so
     long as any such amendment is not disadvantageous to the Holders in any
     material respect or any transaction contemplated thereby (including
     pursuant to any amendment thereto); (ii) any transaction between the
     Company and any Wholly Owned Subsidiary or between Wholly Owned
     Subsidiaries, provided such transactions are not otherwise prohibited by
     this Indenture; (iii) reasonable and customary fees and compensation paid
     to, and indemnity provided on behalf of, officers, directors, employees or
     consultants of the Company or any Subsidiary, as determined by the Board of
     Directors of the Company or any Subsidiary or the senior management thereof
     in good faith; (iv) any Restricted Payments not prohibited by Section 4.13;
     (v) any payments or other transactions pursuant to any tax sharing
     agreement between the Company and any other Person with which the Company
     is required or permitted to file a consolidated tax return or with which
     the Company is or could be part of a consolidated group for tax purposes;
     and (vi) transactions with Continental Airlines, Inc., Mesa Airlines, Inc.
     and their respective Affiliates as contemplated by the Alliance Agreements.
 
     SECTION 4.15  Limitation on Asset Sales.  Subject to the following
paragraphs of this Section, in the event and to the extent that on any date
after the Closing Date the Company and its Subsidiaries shall receive Net Cash
Proceeds from one or more Asset Sales (other than Asset Sales by the Company or
any Subsidiary to the Company or another Subsidiary), then the Company shall, or
shall cause such Subsidiary to, within 12 months after such date apply an amount
equal to such Net Cash Proceeds (A) to repay Indebtedness of the Company or
Indebtedness of any Subsidiary, in each case owing to a Person other than the
Company or any of its Subsidiaries, and/or (B) as an Investment (or enter into a
definitive agreement committing to so invest
 
                                       20
<PAGE>   27
 
within 12 months after the date of such agreement), in property or assets of a
nature or type or that are used in a business (or in a Person having property
and assets of a nature or type, or engaged in a business) similar or related to
the nature or type of the property and assets of, or the business of, the
Company and its Subsidiaries existing on the date thereof (as determined in good
faith by the Board of Directors of the Company or such Subsidiary, as the case
may be, whose determination shall be conclusive and evidenced by a Board
Resolution). The amount of such Net Cash Proceeds required to be applied (or to
be committed to be applied) during such 12-month period as set forth in clause
(A) or (B) of the preceding sentence shall constitute "Excess Proceeds."
 
     If on the first Business Day following any 12-month period referred to in
the preceding paragraph, the aggregate amount of Excess Proceeds from all Asset
Sales, not previously applied as provided in clause (A) or (B) of the preceding
paragraph, exceeds $15,000,000, the Company, within 10 Business Days after the
end of any such 12-month period, make an offer to purchase on a pro rata basis
from all Holders (an "Excess Proceeds Offer"), and shall purchase from Holders
accepting such Excess Proceeds Offer, the maximum principal amount (expressed as
an integral multiple of $1,000) of Securities that may be purchased from funds
in an amount equal to all such outstanding Excess Proceeds at a purchase price
equal to 100% of the principal amount of the Securities so purchased, plus
accrued and unpaid interest thereon (if any) to the date of purchase ("Excess
Proceeds Payment"). Upon completion of an Excess Proceeds Offer (or upon
termination of such offer if no repurchases are required), the amount of such
Excess Proceeds relating thereto shall be equal to zero.
 
     The Company shall commence an Excess Proceeds Offer by causing the Trustee
to mail a notice to each Holder stating: (i) that the Excess Proceeds Offer is
being made pursuant to this Section 4.15 and that all Securities validly
tendered will be accepted for purchase; provided, however, that if the aggregate
purchase price of Securities tendered in an Excess Proceeds Offer (including
accrued interest to the date of purchase) exceeds the aggregate amount of the
Excess Proceeds required to be applied in such Excess Proceeds Offer, the
Company shall select the Securities to be purchased on a pro rata basis (with
such adjustments as may be deemed appropriate by the Company so that only
Securities in denominations of $1,000 or integral multiples thereof shall be
purchased); (ii) the purchase price (including the amount of accrued interest)
and the purchase date (which shall be a Business Day no earlier than 30 days nor
later than 60 days from the date such notice is mailed) (the "Excess Proceeds
Purchase Date"); (iii) that any Security not tendered will continue to accrue
interest pursuant to its terms; (iv) that, unless the Company defaults in the
purchase of such Security on the Excess Proceeds Purchase Date, any Security
accepted for purchase pursuant to the Excess Proceeds Offer shall cease to
accrue interest after the Excess Proceeds Purchase Date; (v) that Holders
electing to have a Security purchased pursuant to the Excess Proceeds Offer will
be required to surrender the Security, together with the form entitled "Option
of the Holder to Elect Purchase" on the reverse side of the Security completed,
to the Paying Agent at the address specified in the notice prior to the close of
business on the Business Day immediately preceding the Excess Proceeds Purchase
Date; (vi) that each Holder will be entitled to withdraw its election (in whole
but not in part) if the Paying Agent receives, not later than the close of
business on the third Business Day immediately preceding the Excess Proceeds
Purchase Date, a telegram, telex, facsimile transmission or letter setting forth
the name of such Holder, the principal amount of Securities delivered for
purchase and a statement that such Holder is withdrawing its election to have
such Securities purchased; and (vii) that Holders whose Securities are being
purchased only in part will be issued new Securities equal in aggregate
principal amount to the unpurchased portion of the Securities surrendered.
 
     On the Excess Proceeds Purchase Date, the Company shall: (i) accept for
purchase on a pro rata basis Securities or portions thereof tendered pursuant to
the Excess Proceeds Offer; (ii) deposit with the Paying Agent money sufficient
to pay the purchase price of all Securities or portions thereof so accepted; and
(iii) deliver, or cause to be delivered, to the Trustee all Securities or
portions thereof so accepted together with an Officers' Certificate specifying
the Securities or portions thereof accepted for purchase by the Company. The
Paying Agent shall promptly mail to the Holders of Securities so accepted
payment in an amount equal to the purchase price, and the Company shall execute
and the Trustee shall promptly authenticate and mail to each such Holders a new
Security equal in principal amount to any unpurchased portion of the Security
 
                                       21

surrendered; provided that each Security purchased and each new Security
delivered shall be in a principal amount of $1,000 or an integral multiple
thereof. The Company will publicly announce the results of the Excess Proceeds
Offer as soon as practicable after the Excess Proceeds Purchase Date. For
purposes of this Section 4.15, the Trustee shall act as the Paying Agent.
 
     Notwithstanding the foregoing:
 
          (i) to the extent that any or all of the Net Cash Proceeds of any
     Asset Sale are prohibited or delayed by applicable local law from being
     repatriated to the United States of America, the portion of such Net Cash
     Proceeds so affected will not be required to be applied pursuant to this
     Section 4.14 but may be retained for so long, but only for so long, as the
     applicable local law will not permit repatriation to the United States of
     America (the Company hereby agrees to promptly take all reasonable actions
     required by the applicable local law to permit such repatriation) and once
     such repatriation of any such affected Net Cash Proceeds is permitted under
     the applicable local law, such repatriation will be immediately effected
     and such repatriated Net Cash Proceeds will be applied in the manner set
     forth in this Section 4.15 as if such Asset Sale had occurred on the date
     of repatriation; and
 
          (ii) to the extent that the Board of Directors of the Company has
     determined in good faith that repatriation of any or all of the Net Cash
     Proceeds would have an adverse tax consequence to the Company, the Net Cash
     Proceeds so affected may be retained outside the United States of America
     for so long as such adverse tax consequences would continue.
 
     The Company will comply with Rule 14e-1 under the Securities Exchange Act
of 1934, as amended, and any other securities laws and regulations thereunder to
the extent such laws and regulations are applicable, in the event that such
Excess Proceeds are received by the Company as contemplated by this Section 4.15
and the Company is required to repurchase Securities as described above.
 
     SECTION 4.16  Limitation on Payment Restrictions Affecting
Subsidiaries.  The Company shall not, and shall not permit any Subsidiary to,
create or otherwise cause or suffer to exist or become effective any Payment
Restriction or consensual encumbrance with respect to any Subsidiary thereof to
(a) pay dividends or make any other distributions on such Subsidiary's Capital
Stock; (b) make any loans or advances to the Company or any other Subsidiary; or
(c) transfer any of its property or assets to the Company or any other
Subsidiary except (i) restrictions imposed by applicable law; (ii) any
restrictions existing under this Indenture; and (iii) encumbrances or
restrictions contained in any agreement or instrument (A) relating to any
property acquired by the Company or any of its Subsidiaries after the Closing
Date, provided that such encumbrance or restriction relates only the property
which is acquired; (B) relating to any Indebtedness of any Subsidiary at the
date of acquisition of such Subsidiary by the Company or any Subsidiary of the
Company, provided that such Indebtedness was not incurred in connection with, or
in contemplation of, such acquisition (the Company being entitled to rely upon a
certificate of such Subsidiary as to whether such Indebtedness was incurred in
contemplation thereof); (C) arising pursuant to an agreement effecting a
refinancing of Indebtedness issued pursuant to an agreement referred to in the
foregoing clauses (A) and (B), so long as the encumbrances and restrictions
contained in any such refinancing agreement are no more restrictive than the
encumbrances and restrictions contained in such agreements; (D) which constitute
customary provisions restricting subletting or assignment of any lease of the
Company or any Subsidiary or provisions in agreements that restrict the
assignment of such agreement or any rights thereunder; and (E) which constitute
restrictions on the sale or other disposition of any property securing
Indebtedness as a result of a lien on such property.
 
     SECTION 4.18  Limitation on Investments.  The Company shall not, and shall
not permit any Subsidiary to make any Investment other than (i) Investments
consisting of non-cash proceeds from Asset Sales permitted by this Indenture;
(ii) Investments in cash and Cash Equivalents; (iii) accounts receivable if
credited or acquired in the ordinary course of business and payable or
dischargeable in accordance with customary trade terms; (iv) payroll advances
and advances for business and travel expenses in the ordinary course of
business; (v) Investments by the Company in its Subsidiaries in the ordinary
course of business; or (vi) Investments by any Subsidiary of the Company in the
Company or in any Subsidiary.

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

     SECTION 5.1  The Company to Furnish Trustee Information as to Names and
Addresses of Securityholders.  If and so long as the Trustee shall not be the
Security registrar for the Securities, the Company covenants and agrees that it
will furnish or cause to be furnished to the Trustee a list in such form as the
Trustee may reasonably require of the names and addresses of the Holders of the
Securities pursuant to Section 312 of the TIA:

     of such record date, and
 
          (b) at such other times as the Trustee may request in writing, within
     30 days after receipt by the Company of any such request as of a date not
     more than 15 days prior to the time such information is furnished.
 
     SECTION 5.2  Disclosure of Names and Addresses of Securityholders.  Each
and every Holder of Securities, by receiving and holding the same, agrees with
the Company and the Trustee that neither the Company nor the Trustee nor any
agent of the Company or the Trustee shall be held accountable by reason of the
disclosure of any such information as to the names and addresses of the Holders
of Securities in accordance with Section 312 of the TIA, regardless of the
source from which such information was derived, and that the Trustee shall not
be held accountable by reason of mailing any material pursuant to a request made
under Section 312(b) of the TIA.
 
     SECTION 5.3  Reports by the Trustee.  Any Trustee's report required under
Section 313(m) of the TIA shall be transmitted on or before May 15 in each year

to the Trustee no more than 60 days prior thereto.

                 CONSOLIDATION, MERGER, CONVEYANCE OR TRANSFER
 
     SECTION 6.1  Merger or Consolidation.  The Company shall not consolidate
with or merge into any other corporation or convey, lease or transfer its
properties and assets substantially as an entirety to any Person, unless:
 
          (a) the corporation formed by such consolidation or into which the
     Company is merged or the Person that acquires by conveyance, lease or
     transfer the properties and assets of the Company substantially as an
     entirety shall be a corporation organized and existing under the laws of
     the United States of America or any State or the District of Columbia, and
     shall expressly assume, by an indenture supplemental hereto, executed and
     delivered to the Trustee, in form satisfactory to the Trustee, the
     Company's obligation for the due and punctual payment of the principal of
     and interest on all the Securities according to their tenor and the
     performance of every covenant of this Indenture on the part of the Company
     to be performed or observed;
 
                                       23
<PAGE>   30
 
          (b) immediately before and after giving effect to such transaction, no
     Event of Default, and no event that, after notice or lapse of time, or
     both, would become an Event of Default, shall have happened and be
     continuing;
 
          (c) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel each stating that such consolidation, merger,
     conveyance, lease or transfer and such supplemental indenture comply with
     this Article and that all conditions precedent herein provided for relating
     to such transaction have been complied with; and
 
          (d) the Person formed by such consolidation or surviving such merger
     or to which the properties and assets of the Company as an entirety or
     substantially as an entirety are transferred or leased shall have a
     Consolidated Tangible Net Worth (immediately after and giving effect to
     such transaction) equal to or greater than that of the Company (immediately
     preceding such transaction).
 
     This Section shall only apply to a merger or consolidation in which the
Company is not the surviving corporation and to conveyances, leases, and
transfers by the Company, as transferee or lessor.
 
     SECTION 6.2  Successor Corporation Substituted.  Upon any consolidation or
merger by the Company with or into any other corporation, or any conveyance or
transfer by the Company of its properties and assets substantially as an
entirety to any Person, in accordance with Section 6.1, the successor
corporation formed by such consolidation or into which the Company is merged or
to which such conveyance or transfer is made shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor corporation had been
named as the Company and in the event of any such conveyance or transfer, the
Company, except in the event of a conveyance by way of lease, shall be
discharged from all obligations and covenants under this Indenture and the
Securities and may be dissolved and liquidated. Such successor corporation may
cause to be signed, and may issue either in its own name or in the name of the
Company prior to such succession, any or all of the Securities issuable
hereunder that theretofore shall not have been signed by the Company or and
delivered to the Trustee; and, upon the order of such successor corporation,
instead of the Company and subject to all the terms, conditions and limitations
in this Indenture prescribed, the Trustee shall authenticate and shall deliver
any Securities that previously shall have been signed and delivered by the
officers of the Company to the Trustee for authentication, and any Securities
that such successor corporation thereafter shall, cause to be signed and
delivered to the Trustee for that purpose. All the Securities so issued shall in
all respects have the same legal rank and benefit under this Indenture as the
Securities theretofore or thereafter issued in accordance with the terms of this
Indenture as though all of such Securities had been issued at the date of the
execution hereof.
 
     In case of any such consolidation, merger, conveyance or transfer, such
changes in phrasing and form (but not in substance) may be made in the
Securities that may be endorsed thereon, as the case may be, thereafter to be
delivered as may be appropriate.

                            REMEDIES OF THE TRUSTEE
                    AND SECURITYHOLDERS ON EVENT OF DEFAULT
 
     SECTION 7.1  Event of Default Defined; Acceleration of Maturity; Waiver of
Default.  "Event of Default", with respect to the Securities, means any one of
the following events that shall have occurred and be continuing (whatever the
reason for such Event of Default and whether it shall be voluntary or
involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body):
 
          (a) default in the payment of the principal of or premium (if any) on
     any Security when the same becomes due and payable at maturity, upon
     acceleration, redemption or otherwise;
 
          (b) default in the payment of interest on any Security when the same
     becomes due and payable, and such default continues for a period of 30
     days;
 
                                       24
<PAGE>   31
 
          (c) the Company defaults in the performance of or breaches any other
     covenant or agreement of the Company in this Indenture or under the
     Securities and such default or breach continues for a period of 30
     consecutive days after the date on which written notice specifying such
     failure, stating that such notice is a "Notice of Default" under the
     Indenture and demanding that the Company remedy the same, shall have been
     given by registered or certified mail, return receipt requested, to the
     Company by the Trustee or to the Company and the Trustee by the Holders of
     25% or more in aggregate principal amount of the Securities Outstanding;
 
          (d) there occurs with respect to any issue or issues of Indebtedness
     of the Company and/or one or more Subsidiaries having an outstanding
     principal amount of $10 million or more in the aggregate for all such
     issues of all such Persons, whether such Indebtedness now exists or shall
     hereafter be created, an event of default that has caused the holder
     thereof to declare such Indebtedness to be due and payable prior to its
     Stated Maturity and such Indebtedness has not been discharged in full or
     such acceleration has not been rescinded or annulled within 30 days of such
     acceleration;
 
          (e) any final judgment or order (not covered by insurance) for the
     payment of money in excess of $10 million in the aggregate for all such
     final judgments or orders against all such Persons (treating any
     deductibles, self-insurance or retention as not so covered) shall be
     rendered against the Company or any Subsidiary and shall not be discharged,
     and there shall be any period of 60 consecutive days following entry of the
     final judgment or order that causes the aggregate amount for all such final
     judgments or orders outstanding against all such Persons to exceed $10
     million during which a stay of enforcement of such final judgment or order,
     by reason of a pending appeal or otherwise, shall not be in effect;
 
          (f) a court having jurisdiction in the premises enters a decree or
     order for (i) relief in respect of the Company or any Subsidiary in an
     involuntary case under any applicable bankruptcy, insolvency or other
     similar law now or hereafter in effect, (ii) appointment of a receiver,
     liquidator, assignee, custodian, trustee, sequestrator or similar official
     of the Company or any Subsidiary or for all or substantially all of the
     property and assets of the Company or any Subsidiary or (iii) the winding
     up or liquidation of the affairs of the Company or any Subsidiary and, in
     each case, such decree or order shall remain unstayed and in effect for a
     period of 60 consecutive days;
 
          (g) the Company or any Subsidiary (i) commences a voluntary case under
     any applicable bankruptcy, insolvency or other similar law now or hereafter
     in effect, or consents to the entry of an order for relief in an
     involuntary case under any such law, (ii) consents to the appointment of or
     taking possession by a receiver, liquidator, assignee, custodian, trustee,
     sequestrator or similar official of the Company or any Subsidiary or for
     all or substantially all of the property and assets of the Company or any
     Subsidiary or (iii) effects any general assignment for the benefit of
     creditors of the Company or any Subsidiary;
 
          (h) the Company and/or one or more Subsidiaries fail to make at the
     final (but not any interim) fixed maturity of one or more issues of
     Indebtedness a principal payment or principal payments aggregating more
     than $10 million and all such defaulted payments shall not have been made,
     waived or extended within 30 days of the payment default that caused the
     aggregate amount of such defaulted payments to exceed $10 million; or
 
          (i) any of the Applicable Documents shall cease, for any reason, to be
     in full force and effect in any material respect, except as a result of an
     amendment, waiver or termination thereof as contemplated or permitted
     therein.
 
     If an Event of Default (other than an Event of Default specified in clause
(f) or (g) above that occurs with respect to the Company) occurs and is
continuing, the Trustee or the Holders of at least 25% of the aggregate
principal amount of the Securities then Outstanding, by written notice to the
Company (and to the Trustee if such notice is given by the Holders (the
"Acceleration Notice" )), may, and the Trustee at the request of the Holders
shall, declare the entire unpaid principal, premium (if any) and accrued
interest on the Securities to be immediately due and payable as specified below.
Upon a declaration of acceleration, such principal, premium (if any) and accrued
interest shall be immediately due and payable. In the event of a
 
                                       25
<PAGE>   32
 
declaration of acceleration because an Event of Default set forth in clause (d)
above has occurred and is continuing, such declaration of acceleration shall be
automatically rescinded and annulled if the event of default triggering such
Event of Default shall be remedied, cured by the Company or waived by the
holders of the relevant Indebtedness within 30 days after the occurrence of the
Event of Default with respect thereto and the Company has delivered an Officer's
Certificate as to such effect. If an Event of Default specified in clause (f) or
(g) above occurs with respect to the Company, all unpaid principal of, premium
(if any) and accrued interest on the Securities then outstanding shall ipso
facto become and be immediately due and payable without declaration or other act
on the part of the Trustee or any Holder.
 
     The Holders of at least a majority in principal amount of the outstanding
Securities, by written notice to the Company and the Trustee, may waive all past
defaults and rescind and annul a declaration of acceleration and its
consequences if (i) all existing Events of Default, other than the non-payment
of the principal of, premium, if any, and interest on Securities that have
become due solely by such declaration of acceleration, have been cured or waived
and (ii) the rescission would not conflict with any judgment or decree of a
court of competent jurisdiction.
 
     Upon receipt by the Trustee of any Notice of Default pursuant to this
Section 7.1 with respect to Securities all or part of which are represented by a
Global Security, a record date shall be established for determining Holders of
Outstanding Securities entitled to join in such Notice of Default, which record
date shall be at the close of business on the day the Trustee receives such
Notice of Default. The Holders on such record date, or their duly designated
proxies, and only such Persons, shall be entitled to join in such Notice of
Default, whether or not such Holders remain Holders after such record date;
provided, that unless Holders of at least 25% in principal amount of the
Outstanding Securities, or their proxies, shall have joined in such Notice of
Default prior to the day which is 90 days after such record date, such Notice of
Default shall automatically and without further action by any Holder be
cancelled and of no further effect. Nothing in this paragraph shall prevent a
Holder, or a proxy of a Holder, from giving, after expiration of such 90-day
period, a new Notice of Default identical to a Notice of Default which has been
cancelled pursuant to the proviso to the preceding sentence, in which event a
new record date shall be established pursuant to the provisions of this Section
7.1.
 
     Upon receipt by the Trustee of any Acceleration Notice or any rescission
and annulment thereof, with respect to Securities all or part of which are
represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Securities entitled to join in such notice,
which record date shall be at the close of business on the day the Trustee
receives such notice. The Holders on such record date, or their duly designated
proxies, and only such Persons, shall be entitled to join in such notice,
whether or not such Holders remain Holders after such record date; provided,
that unless such declaration of acceleration, or rescission and annulment, as
the case may be, shall have become effective by virtue of the requisite
percentage having joined in such notice prior to the day which is 90 days after
such record date, such notice of declaration of acceleration or rescission and
annulment, as the case may be, shall automatically and without further action by
any Holder be cancelled and of no further effect. Nothing in this paragraph
shall prevent a Holder, or a proxy of a Holder, from giving, after expiration of
such 90-day period, a new written notice of declaration of acceleration, or
rescission and annulment thereof, as the case may be, that is identical to a
written notice which has been cancelled pursuant to the proviso to the preceding
sentence, in which event a new record date shall be established pursuant to the
provisions of this Section 7.1.
 
     SECTION 7.2  Collection of Indebtedness by Trustee; Trustee May Prove
Debt.  The Company covenants that (a) in case default shall be made in the
payment of any installment of interest on any of the Securities when such
interest shall have become due and payable, and such default shall have
continued for a period of 30 days or (b) in case default shall be made in the
payment of all or any part of the principal of any of the Securities when the
same shall have become due and payable, whether upon maturity of the Securities
or upon any redemption or by declaration or otherwise, then upon demand of the
Trustee, the Company will pay to the Trustee for the benefit of the Holders of
the Securities the whole amount that then shall have become due and payable an
all Securities for principal or interest, as the case may be (with interest to
the date of such payment upon the overdue principal and, to the extent that
payment of such interest is enforceable under applicable law, on overdue
installments of interest at the same rate as the rate of interest specified in
the
 
                                       26
<PAGE>   33
 
Securities); and in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, including reasonable compensation
to the Trustee and each predecessor Trustee, their respective agents, attorneys
and counsel, and any expenses and liabilities incurred, and all advances made by
the Trustee and each predecessor Trustee except as a result of its negligence or
bad faith.
 
     Until such demand is made by the Trustee, the Company may pay the principal
of and interest on the Securities to the registered Holders, whether or not the
Securities are overdue.
 
     In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any action or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceedings to judgment or final decree, and may enforce any such
judgment or final decree against the Company or other obligor upon the
Securities and collect in the manner provided by law out of the property of the
Company or other obligor upon the Securities, wherever situated the monies
adjudged or decreed to be payable.
 
     In case there shall be pending proceedings relative to the Company or any
other obligor upon the Securities under Title 11 of the United States Code or
any other applicable Federal or state bankruptcy, insolvency or other similar
law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Company or the property of the Company or such other
obligor, or in case of any other judicial proceedings relative to the Company or
other obligor upon the Securities, or to the creditors or property of the
Company or such other obligor, the Trustee, irrespective of whether the
principal of the Securities shall then be due and payable as therein expressed
or by declaration or otherwise and irrespective of whether the Trustee will have
made any demand pursuant to the provisions of this Section, shall be entitled
and empowered, by intervention in such proceedings or otherwise:
 
          (a) to file and prove a claim or claims for the whole amount of
     principal and interest owing and unpaid in respect of the Securities and to
     file such other papers or documents as may be necessary or advisable in
     order to have the claims of the Trustee (including any claim for reasonable
     compensation to the Trustee and each predecessor Trustee and their
     respective agents, attorneys and counsel, and for reimbursement of all
     expenses and liabilities incurred, and all advances made, by the Trustee
     and each predecessor Trustee, except as a result of negligence or bad
     faith) and of the Securityholders allowed in any judicial proceedings
     relative to the Company or other obligor upon the Securities, or to the
     creditors or property of the Company or such other obligor,
 
          (b) unless prohibited by applicable law and regulations, to vote on
     behalf of the Holders of the Securities in any election of a trustee or a
     standby trustee in arrangement, reorganization, liquidation or other
     bankruptcy or insolvency proceedings or person performing similar functions
     in comparable proceedings, and
 
          (c) to collect and receive any monies or other property payable or
     deliverable on any such claims, and to distribute all amounts received with
     respect to the claims of the Securityholders and of the Trustee on their
     behalf; and any trustee, receiver, or liquidator, custodian or other
     similar official is hereby authorized by each of the Securityholders to
     make payments to the Trustee, and, in the event that the Trustee shall
     consent to the making of payments directly to the Securityholders, to pay
     to the Trustee such amounts as shall be sufficient to cover reasonable
     compensation to the Trustee, each predecessor Trustee and their respective
     agents, attorneys and counsel, and all other expenses and liabilities
     incurred, and all advances made, by the Trustee and each predecessor
     Trustee except as a result of negligence or bad faith.
 
     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or vote for or accept or adopt on behalf of any
Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Securityholder in
any such proceeding except, as aforesaid, to vote for the election of a trustee
in bankruptcy or similar person.

     All rights of action and of asserting claims under this Indenture, or under
any of the Securities may be enforced by the Trustee without the possession of
any of the Securities or the production thereof on any trial or other
proceedings relative thereto, and any such action or proceedings instituted by
the Trustee shall be brought in its own name as trustee of an express trust, and
any recovery of judgment, subject to the payment of the expenses, disbursements
and compensation of the Trustee, each predecessor Trustee and their respective
agents and attorneys, shall be for the ratable benefit of the Holders of the
Securities in respect of which such judgment has been recovered.
 
     In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the Holders
of the Securities in respect of which such action was taken, and it shall not be
necessary to make any Holders of such Securities parties to any such
proceedings.
 
     SECTION 7.3  Application of Proceeds.  Any monies collected by the Trustee
pursuant to this Article Seven in respect of the Securities shall be applied in
the following order at the date or dates fixed by the Trustee and, in the case
of the distribution of such monies on account of principal or interest, upon
presentation of the several Securities in respect of which monies have been
collected and stamping (or otherwise noting) thereon the payment, or issuing
Securities in reduced principal amounts in exchange for the presented Securities
if only partially paid, or upon surrender thereof if fully paid:
 
          FIRST: To the payment of amounts due the Trustee or any predecessor
     Trustee under Section 8.6;
 
          SECOND: In case the principal of the Securities shall not have become
     and be then due and payable, to the payment of interest on the Securities
     in default in the order of the maturity of the installments of such
     interest, with interest (to the extent that such interest has been
     collected by the Trustee) upon the overdue installments of interest at the
     same rate as the rate of interest specified in the Securities, such
     payments to be made ratably to the persons entitled thereto, without
     discrimination or preference;
 
          THIRD: In case the principal of the Securities shall have become and
     shall be then due and payable, to the payment of the whole amount then
     owing and unpaid upon all the Securities for principal and interest, with
     interest upon the overdue principal, and (to the extent that such interest
     has been collected by the Trustee) upon overdue installments of interest at
     the same rate as the rate of interest specified in the Securities and in
     case such monies shall be insufficient to pay in full the whole amount so
     due and unpaid upon the Securities, then to the payment of such principal
     and interest without preference or priority of principal over interest or
     of interest over principal, or of any installment of interest over any
     other installment of interest, or of any Security over any other Security,
     ratably to the aggregate of such principal and accrued and unpaid interest;
     and
 
          FOURTH: To the payment of the remainder, if any, to the Company or any
     other person lawfully entitled thereto.
 
     SECTION 7.4  Suits for Enforcement.  In case an Event of Default has
occurred, has not been waived and is continuing, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.
 
     SECTION 7.5  Restoration of Rights on Abandonment of Proceedings.  In case
the Trustee shall have proceeded to enforce any right under this Indenture and
such proceedings shall have been discontinued or abandoned for any reason, or
shall have been determined adversely to the Trustee, then and in every such case
the Company and the Trustee shall be restored respectively to their former
positions and rights hereunder, and all rights, remedies and powers of the
Company, the Trustee and the Securityholders shall continue as though no such
proceedings had been taken.

<PAGE>   35
 
     SECTION 7.6  Limitations on Suits by Securityholders.  A Holder of
Securities may not pursue any remedy with respect to this Indenture or the
Securities unless; (i) such Holder gives to the Trustee written notice of a
continuing Event of Default; (ii) the Holders of at least 25% in aggregate
principal amount of outstanding Securities make a written request to the Trustee
to pursue the remedy; (iii) such Holder or Holders offer to the Trustee
indemnity satisfactory to the Trustee against any costs, liability or expense;
(iv) the Trustee does not comply with the request within 60 days after receipt
of the request and the offer of indemnity; and (v) during such 60-day period,
the Holders of a majority in aggregate principal amount of the outstanding
Securities do not give the Trustee a direction that is inconsistent with the
request.
 
     For purposes of this Section 7.6, the Trustee shall comply with Section
316(a) of the TIA in making any determination of whether the Holders of the
required aggregate principal amount of outstanding Securities have concurred in
any request or direction of the Trustee to pursue any remedy available to the
Trustee or the Holders with respect to this Indenture or the Securities or
otherwise under the law.
 
     A Holder of Securities may not use this Indenture to prejudice the rights
of another Holder or to obtain a preference or priority over such other Holder.
 
     SECTION 7.7  Unconditional Right of Securityholders to Institute Certain
Suits.  Notwithstanding any other provision in this Indenture and any provision
of any Security, the right of any Holder of any Security to receive payment of
the principal of, premium (if any) and interest on such Security on or after the
respective due dates expressed in such Security, or to institute suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.
 
     SECTION 7.8  Powers and Remedies Cumulative; Delay or Omission Not Waiver
of Default.  Except as provided in Section 7.6, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.
 
     No delay or omission of the Trustee or of any Holder to exercise any right
or power accruing upon any Event of Default occurring and continuing as
aforesaid shall impair any such right or power or shall be construed to be a
waiver of any such Event of Default or an acquiescence therein; and, subject to
Section 7.6, every power and remedy given by this Indenture or by law to the
Trustee or to the Holders may be exercised from time to time, and as often as
shall be deemed expedient, by the Trustee or by the Holders.
 
     SECTION 7.9  Control by Holders of Securities.  The Holders of a majority
in aggregate principal amount of the Securities at the time outstanding shall
have the right to direct the time, method, and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred on the Trustee with respect to the Securities by this Indenture;
provided, that such direction shall not be otherwise than in accordance with law
and the provisions of this Indenture; and provided, further, that (subject to
the provisions of Section 8.1) the Trustee shall have the right to decline to
follow any such direction if the Trustee, being advised by counsel, shall
determine that the action or proceeding so directed may not lawfully be taken or
if the Trustee in good faith by its board of directors, the executive committee,
or a trust committee of directors or Responsible Officers of the Trustee shall
determine that the action or proceedings so directed would involve the Trustee
in personal liability or if the Trustee in good faith shall so determine that
the actions or forbearances specified in or pursuant to such direction would be
unduly prejudicial to the interests of Holders not joining in the giving of said
direction. It being understood that (subject to Section 8.1) the Trustee shall
have no duty to ascertain whether or not such actions or forbearances are unduly
prejudicial to such Holders.
 
     Nothing in this Indenture shall impair the right of the Trustee in its
discretion to take any action deemed proper by the Trustee and that is not
inconsistent with such direction or directions by the Holders.
 
     Upon receipt by the Trustee of any written notice directing the time,
method or place of conducting any such proceeding or exercising any such trust
or power, with respect to Securities all or part of which are
 
                                       29
<PAGE>   36
 
represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Securities entitled to join in such notice,
which record date shall be at the close of business on the day the Trustee
receives such notice. The Holders on such record date, or their duly designated
proxies, and only such Persons, shall be entitled to join in such notice,
whether or not such Holders remain Holders after such record date; provided,
that unless the Holders of a majority in principal amount of the Outstanding
Securities shall have joined in such notice prior to the day which is 90 days
after such record date, such notice shall automatically and without further
action by any Holder be cancelled and of no further effect. Nothing in this
paragraph shall prevent a Holder, or a proxy of a Holder, from giving, after
expiration of such 90-day period, a new notice identical to a notice which has
been cancelled pursuant to the proviso to the preceding sentence, in which event
a new record date shall be established pursuant to the provisions of this
Section 7.9.
 
     SECTION 7.10  Waiver of Past Defaults.  Subject to Sections 7.1 and 7.7,
the Holders of at least a majority in principal amount of the outstanding
Securities, by notice to the Trustee, may waive an existing Event of Default and
its consequences, except a default in the payment of principal of or interest on
any Security as specified in clause (a) or (b) of Section 7.1.
 
     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Persons entitled to waive any past default hereunder.
If a record date is fixed, the Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to waive any
default hereunder, whether or not such Holders remain Holders after such record
date; provided, that unless such majority in principal amount shall have waived
such default prior to the date which is 90 days after such record date, any such
waiver previously given shall automatically and without further action by any
Holder be cancelled and of no further effect.
 
     Upon any such waiver, such Default shall cease to exist and be deemed to
have been cured and not to have occurred, and any Event of Default arising
therefrom shall be deemed to have been cured, and not to have occurred for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default at Event of Default or impair any right consequent thereon.
 
     SECTION 7.11  Trustees to Give Notice of Default, But May Withhold in
Certain Circumstances.  The Trustee shall, within ninety days after the
occurrence of a Default with respect to the Securities, give notice of all
Defaults known to the Trustee to all Holders of Securities in the manner and to
the extent provided in Section 313(c) of the TIA, unless in each case such
Defaults shall have been cured before the mailing or publication of such notice;
provided, however, that, except in the case of Default in the payment of the
principal of or interest on any of the Securities, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee, or a trust committee of directors or trustees or
Responsible Officers of the Trustee, or any combination of the foregoing, in
good faith determines that the withholding of such notice is in the interests of
the Securityholders.
 
     SECTION 7.12  Right of Court to Require Filing of Undertaking to Pay
Costs.  All parties to this Indenture agree, and each Holder of any Security by
its acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken, suffered
or omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merit and good
faith of the claims or defenses made by such party litigant; but the provisions
of this Section shall not apply to any suit instituted by the Trustee, to any
suit instituted by any Securityholder or group of Securityholders holding in the
aggregate more than 10% in aggregate principal amount of the Securities or to
any suit instituted by any Securityholder for the enforcement of the payment of
the principal of or interest on any Security on or after the due date expressed
in such Security or any date fixed for redemption.

                             CONCERNING THE TRUSTEE
 
     SECTION 8.1  Duties and Responsibilities of the Trustee; During Default;
Prior to Default.  With respect to the Holders of the Securities issued
hereunder, the Trustee, prior to the occurrence of an Event of Default with
respect to the Securities and after the curing or waiving of all Events of
Default that may have occurred, has undertaken to perform such duties and only
such duties as are specifically set forth in this Indenture. In case an Event of
Default with respect to the Securities has occurred (that has not been cured or
waived), the Trustee shall exercise with respect to such Securities such of the
rights and powers vested in it by this Indenture, and use the same degree of
care and skill in their exercise, as a prudent man would exercise or use under
the circumstances in the conduct of his own affairs.
 
     No provision of this Indenture shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or
its own wilful misconduct, except that:
 
          (a) prior to the occurrence of an Event of Default with respect to the
     Securities and after the curing or waiving of all such Events of Default
     with respect to such Securities that may have occurred:
 
             (i) the duties and obligations of the Trustee with respect to the
        Securities shall be determined solely by the express provisions of this
        Indenture, and the Trustee shall not be liable except for the
        performance of such duties and obligations as are specifically set forth
        in this Indenture, and no implied covenants or obligations shall be read
        into this Indenture against the Trustee; and
 
             (ii) in the absence of bad faith on the part of the Trustee, the
        Trustee may conclusively rely, as to the truth of the statements and the
        correctness of the opinions expressed therein, upon any statements,
        certificates or opinions furnished to the Trustee and conforming to the
        requirements of this Indenture; but in the case of any such statements,
        certificates or opinions that by any provision hereof are specifically
        required to be furnished to the Trustee, the Trustee shall be under a
        duty to examine the same to determine whether or not they conform to the
        requirements of this Indenture;
 
          (b) the Trustee shall not be liable for any error of judgment made in
     good faith by a Responsible Officer or Responsible Officers of the Trustee,
     unless it shall be proved that the Trustee was negligent in ascertaining
     the pertinent facts; and
 
          (c) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the Holders pursuant to Section 7.9 relating to the time, method and
     place of conducting any proceeding for any remedy available to the Trustee,
     or exercising any trust or power conferred upon the Trustee, under this
     Indenture.
 
     None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there shall be reasonable ground for believing that the
repayment of such funds or adequate indemnity against such liability is not
reasonably assured to it.
 
     Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.
 
     The provisions of this Section 8.1 are in furtherance of and subject to
Section 315 of the TIA.
 
     SECTION 8.2  Certain Rights of the Trustee.  In furtherance of and subject
to the TIA, and subject to Section 8.1:
 
          (a) the Trustee may rely and shall be protected in acting or
     refraining from acting upon any resolution, Officers' Certificate or any
     other certificate, statement, instrument, opinion, report, notice, request,
     consent, order, bond, debenture, note, coupon, security or other paper or
     document believed by it to be genuine and to have been signed or presented
     by the proper party or parties;
 
          (b) any request, direction, order or demand of the Company mentioned
     herein shall be sufficiently evidenced by an Officers' Certificate of the
     Company (unless other evidence in respect thereof be herein
 
                                       31
<PAGE>   38
 
     specifically prescribed); and any resolution of the Board of Directors of
     the Company may be evidenced to the Trustee by a copy thereof certified by
     the secretary or an assistant secretary of the Company;
 
          (c) the Trustee may consult with counsel and any written advice or any
     Opinion of Counsel shall be full and complete authorization and protection
     in respect of any action taken, suffered or omitted to be taken by it
     hereunder in good faith and in reliance thereon in accordance with such
     advice or Opinion of Counsel;
 
          (d) the Trustee shall be under no obligation to exercise any of the
     trusts or powers vested in it by this Indenture at the request, order or
     direction of any of the Securityholders pursuant to the provisions of this
     Indenture, unless such Securityholders shall have offered to the Trustee
     reasonable security or indemnity against the costs, expenses and
     liabilities that might be incurred therein or thereby;
 
          (e) the Trustee shall not be liable for any action taken or omitted by
     it in good faith and believed by it to be authorized or within the
     discretion, rights or powers conferred upon it by this Indenture; and
 
          (f) prior to the occurrence of an Event of Default hereunder and after
     the curing or waiving of all Events of Default, the Trustee shall not be
     bound to make any investigation into the facts or matters stated in any
     resolution, certificate, statement, instrument, opinion, report, notice,
     request, consent, order, approval, appraisal, bond, debenture, note,
     coupon, security, or other paper or document unless requested in writing to
     so do by the Holders of not less than a majority in aggregate principal
     amount of the Securities then Outstanding; provided, however, that, if the
     payment within a reasonable time to the Trustee of the costs, expenses, or
     liabilities likely to be incurred by it in the making of such investigation
     is, in the opinion of the Trustee, not reasonably assured to the Trustee by
     the security afforded to it by the terms of this Indenture, the Trustee may
     require reasonable indemnity against such expenses or liabilities as a
     condition to proceeding; the reasonable expenses of every such
     investigation shall be paid by the Company or, if paid by the Trustee or
     any predecessor Trustee, shall be repaid by the Company upon demand.
 
     SECTION 8.3  Trustee Not Responsible for Recitals, Disposition of
Securities or Application of Proceeds Thereof.  The recitals contained herein
and in the Securities, except the Trustee's certificates of authentication,
shall be taken as the statements of the Company and the Trustee assumes no
responsibility for the correctness of the same. The Trustee makes no
representation as to the validity or sufficiency of this Indenture or of the
Securities. The Trustee shall not be accountable for the use or application by
the Company of any of the Securities or of the proceeds thereof.
 
     SECTION 8.4  Trustee and Agents May Hold Securities; Collections, etc.  The
Trustee or any agent of the Company or the Trustee, in its individual or any
other capacity, may become the owner or pledgee of Securities with the same
rights it would have if it were not the Trustee or such agent and may otherwise
deal with the Company and receive, collect, hold and retain collections from the
Company with the same rights it would have if it were not the Trustee or such
agent.
 
     SECTION 8.5  Monies Held by Trustee.  Subject to the provisions of Section
11.4 hereof, all monies received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were received,
but need not be segregated from other funds except to the extent required by
mandatory provisions of law. Neither the Trustee nor any agent of the Company or
the Trustee shall be under any liability for interest on any monies received by
it hereunder.
 
     SECTION 8.6  Compensation and Indemnification of Trustee and Its Prior
Claim.  The Company covenants and agrees to pay to the Trustee from time to
time, and the Trustee shall be entitled to, reasonable compensation (which shall
not be limited by any provision of law in regard to the compensation of a
trustee of an express trust) and the Company covenants and agrees to pay or
reimburse the Trustee and each predecessor Trustee upon its request for all
reasonable expenses, disbursements and advances incurred or made by or on behalf
of it in accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all agents and other persons not regularly in its employ) except any such
expense, disbursement or advance as may arise from its negligence or bad faith.
The Company also covenants to indemnify the Trustee and each predecessor Trustee
for, and to
 
                                       32
<PAGE>   39
 
hold it harmless against, any loss, liability or expense incurred, without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration of this Indenture or the trusts hereunder and its
duties hereunder, including the costs and expenses of defending itself against
or investigating any claim of liability in the premises. The obligations of the
Company under this Section to compensate and indemnify the Trustee and each
predecessor Trustee and to pay or reimburse the Trustee and each predecessor
Trustee for expenses, disbursements and advances shall constitute additional
indebtedness of the Company hereunder and shall survive the satisfaction and
discharge of this Indenture. Such additional indebtedness shall be a senior
claim to that of the Securities upon all property and funds held or collected by
the Trustee as such, except funds held in trust for the benefit of the Holders
of particular Securities, and the Securities are hereby subordinated to such
senior claim.
 
     SECTION 8.7  Right of Trustee to Rely on Officers' Certificate,
etc.  Subject to Sections 8.1 and 8.2, whenever in the administration of this
Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or bad faith on the
part of the Trustee, be deemed to be conclusively proved and established by an
Officers' Certificate of the Company delivered to the Trustee, and such
certificate, in the absence of negligence or bad faith on the part of the
Trustee, shall be full warrant to the Trustee for any action taken, suffered or
omitted by it under the provisions of this Indenture upon the faith thereof.
 
     SECTION 8.8  Persons Eligible for Appointment as Trustee.  The Trustee
shall at all times be a corporation organized and doing business under the laws
of the United States of America or of any State or the District of Columbia, or
a corporation or other Person permitted to act as Trustee by the Commission
pursuant to the TIA, having a combined capital and surplus of at least
$50,000,000, and that is authorized under such laws to exercise corporate trust
powers and is subject to supervision or examination by Federal, State or
District of Columbia authority. Such corporation shall have an address in the
Borough of Manhattan, The City of New York for the presentment of Securities. If
such corporation publishes reports of condition at least annually, pursuant to
law or to the requirements of the aforesaid supervising or examining authority,
then for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. In case at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section, the Trustee shall resign immediately in the manner and with the effect
specified in Section 8.9.
 
     The provisions of this Section 8.8 are in furtherance of and subject to
Section 310(a) of the TIA.
 
     SECTION 8.9  Resignation and Removal; Appointment of Successor Trustee.
 
          (a) The Trustee, or any trustee or trustees hereafter appointed, may
     at any time resign by giving written notice of resignation to the Company
     and by mailing notice of such resignation to the Holders of then
     Outstanding Securities at their addresses as they shall appear on the
     registry books. Upon receiving such notice of resignation, the Company
     shall promptly appoint a successor trustee or trustees by written
     instrument in duplicate, executed by authority of the Board of Directors of
     the Company, one copy of which instrument shall be delivered to the
     resigning Trustee and one copy to the successor trustee or trustees. If no
     successor trustee shall have been so appointed and have accepted
     appointment within 30 days after the mailing of such notice of resignation,
     the resigning trustee may petition any court of competent jurisdiction for
     the appointment of a successor trustee, or any Securityholder who has been
     a bona fide Holder of a Security or Securities for at least six months may,
     subject to the provisions of Section 8.12, on behalf of itself and all
     others similarly situated, petition any such court for the appointment of a
     successor trustee. Such court may thereupon, after such notice, if any, as
     it may deem proper and prescribe, appoint a successor trustee.
 
          (b) In case at any time any of the following shall occur:
 
             (i) the Trustee shall fail to comply with the provisions of Section
        310(b) of the TIA with respect to the Securities after written request
        therefor by the Company or by any Securityholder who has been a bona
        fide Holder of a Security or Securities for at least six months; or
 
                                       33
<PAGE>   40
 
             (ii) the Trustee shall cease to be eligible in accordance with the
        provisions of Section 8.8 and Section 310(a) of the TIA and shall fail
        to resign after written request therefor by the Company or by any
        Securityholder; or
 
             (iii) the Trustee shall become incapable of acting or shall be
        adjudged a bankrupt or insolvent, or a receiver or liquidator of the
        Trustee or of its property shall be appointed, or any public officer
        shall take charge or control of the Trustee or of its property or
        affairs for the purpose of rehabilitation, conservation or liquidation;
 
     then, in any such case, unless the Trustee's duty to resign has been stayed
     as provided pursuant to Section 310(b) of the TIA, the Company may remove
     the Trustee and appoint a successor trustee by written instrument, in
     duplicate, executed by order of the Board of Directors of the Company, one
     copy of which instrument shall be delivered to the Trustee so removed and
     one copy to the successor trustee, or, subject to the provisions of Section
     315(e) of the TIA, any Securityholder who has been a bona fide Holder of a
     Security or Securities of such series for at least six months may on behalf
     of himself and all others similarly situated, petition any court of
     competent jurisdiction for the removal of the Trustee and the appointment
     of a successor trustee. Such court may thereupon, after such notice, if
     any, as it may deem proper and prescribe, remove the Trustee and appoint a
     successor trustee.
 
          (c) The Holders of a majority in aggregate principal amount of the
     Securities at the time Outstanding may at any time remove the Trustee and
     appoint a successor trustee by delivering to the Trustee so removed, to the
     successor trustee so appointed, and to the Company the evidence provided
     for in Section 9.1 of the action in that regard taken by the
     Securityholders.
 
          (d) Any resignation or removal of the Trustee and any appointment of a
     successor trustee pursuant to any of the provisions of this Section 8.9
     shall become effective upon acceptance of appointment by the successor
     trustee as provided in Section 8.10.
 
     SECTION 8.10  Acceptance of Appointment by Successor Trustee.  Any
successor trustee appointed as provided in Section 8.9 shall execute and deliver
to the Company and to its predecessor Trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor Trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all rights,
powers, duties and obligations of its predecessor hereunder, with like effect as
if originally named as trustee hereunder; but nevertheless, on the written
request of the Company or of the successor trustee, upon payment of its charges
then unpaid, the Trustee ceasing to act shall, subject to Section 11.4, pay over
to the successor trustee all monies at the time held by it hereunder and shall
execute and deliver an instrument transferring to such successor trustee all
such rights, powers, duties and obligations. Upon request of any such successor
trustee, the Company shall execute any and all instruments in writing for more
fully and certainly vesting in and confirming to such successor trustee all such
rights and powers. Any Trustee ceasing to act shall, nevertheless, retain a
prior claim upon all property or funds held or collected by such trustee to
secure any amounts then due it pursuant to the provisions of Section 8.6.
 
     No successor trustee shall accept appointment as provided to this Section
8.10 unless at the time of such acceptance such successor trustee shall be
qualified under Section 310(b) of the TIA and eligible under the provisions of
Section 8.8.
 
     Upon acceptance of appointment by any successor trustee as provided in this
Section 8.10, the Company shall give notice thereof to the Holders of
Securities, by mailing such notice to such Holders at their addresses as they
shall appear on the registry books. If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for
by the preceding sentence may be combined with the notice called for by Section
8.9. If the Company fails to give such notice within ten days after acceptance
of appointment by the successor trustee, the successor trustee shall cause such
notice to be given at the expense of the Company.
 
     SECTION 8.11  Merger, Conversion, Consolidation or Succession to Business
of Trustee.  Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
 
                                       34
<PAGE>   41
 
any corporation succeeding to the corporate trust business of the Trustee, shall
be the successor of the Trustee hereunder; provided, however, that such
corporation shall be qualified under Section 310(b) of the TIA and eligible
under the provisions of Section 8.8, without the execution or filing of any
paper or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding.
 
     In case at the time such successor to the Trustee shall succeed to the
trust created by this Indenture any of the Securities shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the
certificate of authentication of any predecessor Trustee and deliver such
Securities so authenticated; and, in case at that time any of the Securities
shall not have been authenticated, any successor to the Trustee may authenticate
such Securities either in the name of any predecessor Trustee hereunder or in
the name of the successor Trustee; and in all such cases such certificate shall
have the full force that it has anywhere in the Securities or in this Indenture
provided that the certificate of the Trustee shall have; provided, however, that
the right to adopt the certificate of authentication of any predecessor Trustee
or to authenticate Securities in the name of any predecessor Trustee shall apply
only to its successor or successors by merger, conversion or consolidation.
 
     SECTION 8.12  Preferential Collection of Claims Against the Company.  The
Trustee shall comply with Section 311(a) of the TIA. Any Trustee that has
resigned or been removed is subject to Section 311(s) of the TIA to the extent
indicated therein.
 
     SECTION 8.13  Appointment of Authenticating Agent.  As long as any
Securities remain Outstanding, the Trustee may, by an instrument in writing,
appoint an authenticating agent (the "Authenticating Agent") that shall be
authorized to act on behalf of the Trustee to authenticate Securities, including
Securities issued upon exchange, registration of transfer, partial redemption or
pursuant to Section 2.5. Securities authenticated by such Authenticating Agent
shall be entitled to the benefits of this Indenture and shall be valid and
obligatory for all purposes as if authenticated by the Trustee. Whenever
reference is made in this Indenture to the authentication and delivery of
Securities by the Trustee or to the Trustee's Certificate of Authentication
(including, without limitation, in Section 2.3), such reference shall be deemed
to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a Certificate of Authentication executed on behalf of
the Trustee by such Authenticating Agent. Such Authenticating Agent shall at all
times be a corporation organized and doing business under the laws of the United
States of America or of any State or the District of Columbia, authorized under
such laws to exercise corporate trust powers, having a combined capital and
surplus of at least $5,000,000 (determined as provided in Section 8.8 with
respect to the Trustee) and subject to supervision or examination by Federal or
State authority.
 
     Any corporation into which any Authenticating Agent may be merged or
converted, or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency business
of any Authenticating Agent, shall continue to be the Authenticating Agent with
respect to all Securities for which it served as Authenticating Agent without
the execution or filing of any paper or any further act on the part of the
Trustee or such Authenticating Agent. Any Authenticating Agent may at any time,
and if it shall cease to be eligible shall, resign by giving written notice of
resignation to the Trustee and to the Company.
 
     Upon receiving such a notice of resignation or upon such a termination, or
in case at any time any Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section 8.13, the Trustee shall upon
receipt of an Company Order appoint a successor Authenticating Agent and the
Company shall provide notice of such appointment to all Holders in the manner
and to the extent provided in Section 12.4. Any successor Authenticating Agent
upon acceptance of its appointment hereunder shall become vested with all
rights, powers, duties and responsibilities of its predecessor hereunder, with
like effect as if originally named as Authenticating Agent. The Company agrees
to pay to the Authenticating Agent from time to time reasonable compensation.
The Authenticating Agent for the Securities shall have no responsibility or
liability for any action taken by it as such at the direction of the Trustee.
 
     Sections 8.2, 8.3, 8.4, 8.6, 8.8 and 9.3 shall be applicable to any
Authenticating Agent as if each reference to "Trustee" therein referred to the
Authenticating Agent.

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

                                   AMENDMENTS
 
     SECTION 10.1  Amendments and Supplements Permitted Without Consent of
Holders.
 
          (a) Notwithstanding Section 10.2, the Company and the Trustee may
     amend or supplement this Indenture or the Securities without the consent of
     any Holder to: (i) cure any ambiguity, correct or supplement any provisions
     herein which may be inconsistent with any other provision herein, or to
     make any other provisions with respect to matters or questions arising
     under this Indenture which shall not be inconsistent with the provisions of
     this Indenture; provided that such amendment does not adversely affect the
     rights of the Holders; (ii) provide for uncertificated Securities in
     addition to or in place of certificated Securities; (iii) evidence the
     succession of another corporation to the Company and provide for the
     assumption by such successor of the Company's obligations to the Holders
     hereunder and under the Notes as permitted under Article Six; (iv) make any
     change that would (1) provide any additional rights or benefits to Holders
     or (2) not adversely affect the legal rights under the Indenture of any
     Holder, or (v) comply with the requirements of the Commission in order to
     effect or maintain the qualification of this Indenture under the TIA.
 
          (b) Upon the Company's request, after receipt by the Trustee of a
     resolution of the Board of Directors authorizing the execution of any
     amended or supplemental indenture, and the documents described in Section
     10.6, the Trustee shall join with the Company in the execution of any
     amended or supplemental indenture authorized or permitted by the terms of
     this Indenture and to make any further appropriate agreements and
     stipulations that may be contained in any such amended or supplemental
     indenture, but the Trustee shall not be obligated to enter into an amended
     or supplemental indenture that affects its own rights, duties or immunities
     under this Indenture or otherwise.
 
     SECTION 10.2  Amendments and Supplements Requiring Consent of Holders.
 
          (a) Except as otherwise provided in Section 10.1(a) and 10.2(c), this
     Indenture and the Securities may be amended or supplemented with the
     written consent of the Holders of at least a majority in aggregate
     principal amount of the then outstanding Securities (including consents
     obtained in connection with a tender offer or exchange offer for the
     Securities), and any existing Default or Event of Default or non-compliance
     with any provision of the Indenture or the Securities may be waived with
     the consent of
 
                                       37
<PAGE>   44
 
     Holders of at least a majority in principal of the then outstanding
     Securities (including consents obtained in connection with a tender offer
     or exchange offer for the Securities).
 
          (b) Upon the Company's request and after receipt by the Trustee of a
     resolution of the Board of Directors authorizing the execution of any
     supplemental indenture, evidence of the Holders' consent, and the documents
     described in Section 10.6, the Trustee shall join with the Company in the
     execution of such amended or supplemental indenture unless such amended or
     supplemental indenture affects the Trustee's own rights, duties or
     immunities under this Indenture or otherwise, in which case the Trustee may
     in its discretion, but shall not be obligated to, enter into such amended
     or supplemental indenture.
 
          (c) Without the consent of each Holder affected, no amendment,
     supplement or waiver to this Indenture shall: (i) reduce the principal
     amount of Securities whose Holders must consent to an amendment, supplement
     or waiver of any provision of this Indenture on the Securities, (ii) reduce
     the principal of or change the fixed maturity of any Security, or alter the
     provisions with respect to the redemption of the Securities in a manner
     adverse to the Holders, (iii) reduce the rate of or change the time for
     payment of interest on any Security, (iv) waive a Default or Event of
     Default in the payment of principal of, or premium (if any) or interest on,
     the Securities (except that Holders of at least a majority in aggregate
     principal amount of the then outstanding Securities may (1) rescind an
     acceleration of the Securities that resulted from a non-payment default,
     and (2) waive the payment default that resulted from such acceleration),
     (v) make any Security payable in money other than U.S. Legal Tender, (vi)
     make any change in the provisions of the Indenture relating to waivers of
     past Defaults or the rights of Holders to receive payments of principal of,
     or premium (if any) or interest on, the Securities, (vii) waive a
     redemption payment with respect to any Security, or (ix) make any change in
     Section 7.7, Section 7.10 or this sentence.
 
          (d) The Company may, but shall not be obligated to, fix a record date
     for the purpose of determining the Persons entitled to consent to any
     indenture supplemental hereto. If a record date is fixed, the Holders on
     such record date, or their duly designated proxies, and only such Persons,
     shall be entitled to consent to such supplemental indenture, whether or not
     such Holders remain Holders after such record date; provided, that unless
     such consent shall have become effective by virtue of the requisite
     percentage having been obtained prior to the date which is 90 days after
     such record date, any such consent previously given shall automatically and
     without further action by any Holder be cancelled and of no further effect.
 
          (e) It shall not be necessary for the consent of the Holders under
     this Section 10.2 to approve the particular form of any proposed amendment
     or waiver, but it shall be sufficient if such consent approves the
     substance thereof. After an amendment, supplement or waiver under this
     Section 10.2 becomes effective, the Company shall mail to each Holder
     affected thereby a notice briefly describing the amendment, supplement or
     waiver. Any failure of the Company to mail such notice, or any defect
     therein, shall not, however, in any way impair or affect the validity of
     any such amended or supplemental indenture or waiver.
 
     SECTION 10.3  Compliance with TIA.  Every amendment or supplement to this
Indenture or the Securities shall be set forth in an amended supplemental
indenture that complies with the TIA as then in effect.
 
     SECTION 10.4  Revocation and Effect of Consents.
 
          (a) Until an amendment, supplement or waiver becomes effective, a
     consent to it by a Holder of a Security is a continuing consent by the
     Holder and every subsequent holder of a Security or portion of a Security
     that evidences the same Indebtedness as the consenting Holder's Security,
     even if notation of the consent is not made on any Security. However, any
     such Holder or subsequent Holder may revoke the consent as to its Security
     or portion of a Security if the Trustee receives the notice of revocation
     before the date on which the Trustee receives an Officers' Certificate
     certifying that the Holders of the requisite principal amount of Securities
     have consented (and not theretofore revoked such consent) to the amendment
     or waiver.
 
                                       38
<PAGE>   45
 
          (b) The Company may, but shall not be obligated to, fix a record date
     for the purpose of determining the holders of Securities entitled to
     consent to any amendment or waiver. If a record date is fixed, then
     notwithstanding the provisions of the immediately preceding paragraph,
     those Persons who were holders of Securities at such record date (or their
     duly designated proxies), and only those Persons, shall be entitled to
     consent to such amendment or waiver or to revoke any consent previously
     given, whether or not such Persons continue to be holders of Securities
     after such record date. No consent shall be valid or effective for more
     than 90 days after such record date.
 
          (c) After an amendment or waiver becomes effective it shall bind every
     Holder, unless it is of the type described in Section 10.2(c), in which
     case the amendment or waiver shall only bind each Holder that consented to
     it and every subsequent holder of a Security that evidences the same debt
     as the consenting Holder's Security.
 
     SECTION 10.5  Notation on or Exchange of Securities.  The Trustee may place
an appropriate notation about an amendment, supplement or waiver on any Security
thereafter authenticated. The Company in exchange for all Securities may issue
and the Trustee shall authenticate new Securities that reflect the amendment,
supplement or waiver. Failure to make the appropriate notation or issue a new
Security shall not affect the validity and effect of such amendment, supplement
or waiver.
 
     SECTION 10.6  Trustee Protected.  The Trustee shall sign any amendment or
supplemental indenture authorized pursuant to this Article Ten if the amendment
does not adversely affect the rights, duties, liabilities or immunities of the
Trustee. If it does, the Trustee may, but need not, sign it. In signing such
amendment or supplemental indenture, the Trustee shall be entitled to receive
and, subject to Section 8.1, shall be fully protected in relying upon, an
Officers' Certificate and Opinion of Counsel as conclusive evidence that such
amendment or supplemental indenture is authorized or permitted by this
Indenture, that it is not inconsistent herewith, and that it will be valid and
binding upon the Company in accordance with its terms. The Company may not sign
an amendment or supplemental indenture until the Board of Directors approves it.

                    SATISFACTION AND DISCHARGE OF INDENTURE;

     SECTION 11.1  Satisfaction and Discharge of Indenture.
 
          (A) Except as otherwise provided in this Section 11.1, the Company may
     terminate its obligations under the Securities and this Indenture with
     respect to the Securities if:
 
             (i) all Securities previously authenticated and delivered (other
        than destroyed, lost or stolen Securities that have been replaced or
        Securities that are paid pursuant to Section 4.1 of this Indenture or
        Securities for whose payment money or securities have theretofore been
        held in trust and thereafter repaid to the Company, as provided in
        Section 11.4 of this Indenture) have been delivered to the Trustee for
        cancellation and the Company has paid all sums payable by it hereunder;
        or
 
             (ii) (A) the Securities mature within one year or all of them are
        to be called for redemption within one year under arrangements
        satisfactory to the Trustee for giving the notice of redemption, (B) the
        Company irrevocably deposits in trust with the Trustee during such
        one-year period, under the terms of an irrevocable trust agreement in
        form and substance satisfactory to the Trustee, as trust funds solely
        for the benefit of the Holders for that purpose, money or U.S.
        Government Obligations sufficient (in the opinion of a nationally
        recognized firm of independent public accountants expressed in a written
        certification thereof delivered to the Trustee), without consideration
        of any reinvestment of any interest thereon, to pay principal and
        interest on the Securities to maturity or redemption, as the case may
        be, and to pay all other sums payable by it hereunder, (C) no Event of
        Default with respect to the Securities shall have occurred and be
        continuing on the date of such deposit, (D) such deposit will not result
        in a breach or violation of, or constitute a default under, this
 
                                       39
<PAGE>   46
 
          Indenture or any other agreement or instrument to which the Company is
          a party or by which either is bound and (E) the Company has delivered
          to the Trustee an Officers' Certificate and an Opinion of Counsel, in
          each case stating that all conditions precedent provided for herein
          relating to the satisfaction and discharge of this Indenture have been
          complied with.
 
     With respect to the foregoing clause (i), the Company's obligations under
Section 8.6 shall survive. With respect to the foregoing clause (ii), the
Company's obligations in Sections 2.2, 2.3, 2.4, 2.5, 2.6, 4.1, 4.2, 4.3, 4.4,
8.6, 8.9, 11.2, 11.4 and 11.5 of this Indenture shall survive until the
Securities are no longer outstanding. Thereafter, only the Company's obligations
in Section 8.6 and 11.2 of this Indenture shall survive. After any such
irrevocable deposit, the Trustee upon request shall acknowledge in writing the
discharge of the Company's obligations under the Securities and this Indenture
with respect to the Securities except for those surviving obligations specified
above.
 
          (B) The Company will be deemed to have paid and will be discharged
     from any and all obligations in respect of the Securities on the 123rd day
     after the deposit referred to in clause (d) of this paragraph, and the
     provisions of this Indenture will no longer be in effect with respect to
     the Securities, except as to (i) rights of registration of transfer and

     lost or stolen Securities, (iii) rights of Holders to receive payments of
     principal thereof and interest thereon, (iv) the Company's obligations
     under Section      , (v) the rights, obligations and immunities of the
     Trustee hereunder and (vi) the rights of the Holders of Securities as
     beneficiaries of this Indenture with respect to the property so deposited
     with the Trustee payable to all or any of them, and the Trustee, at the
     expense of the Company, shall at the Company's request execute proper
     instruments acknowledging the same; provided that the following conditions
     shall have been satisfied:
 
             (a) with reference to this Section 11.1(B), the Company has
        irrevocably deposited or caused to be irrevocably deposited with the
        Trustee (or another trustee satisfying the requirements of Section 8.8)
        and conveyed all right, title and interest for the benefit of the
        Holders of the Securities, under the terms of an irrevocable trust
        agreement in form and substance satisfactory to the Trustee as trust
        funds in trust, in and to (1) money in an amount, (2) U.S. Government
        Obligations that, through the payment of interest and principal in
        respect thereof in accordance with their terms, will provide, not later
        than one day before the due date of any payment referred to in this
        clause (a), money in an amount or (3) a combination thereof in an amount
        sufficient, in the opinion of a nationally recognized firm of
        independent public accountants expressed in a written certification
        thereof delivered to the Trustee, to pay and discharge, without
        consideration of the reinvestment of such interest and after payment of
        all federal, state and local taxes or other charges and assessments in
        respect thereof payable by the Trustee, the principal of, premium, if
        any, and interest on the outstanding Securities at the Stated Maturity
        of such principal or interest; provided that the Trustee shall have been
        irrevocably instructed to apply such money or the proceeds of such U.S.
        Government Obligations to the payment of such principal, premium, if
        any, and interest with respect to the Securities;
 
             (b) such deposit will not result in a breach or violation of, or
        constitute a default under, this Indenture or any other agreement or
        instrument to which the Company is a party or by which either is bound;
 
             (c) the Company shall have delivered to the Trustee (1) either (x)
        a ruling directed to the Trustee received from the Internal Revenue
        Service to the effect that the Holders of Securities will not recognize
        income, gain or loss for federal income tax purposes as a result of the
        Company's exercise of its option under this Section 11.1(B) and will be
        subject to federal income tax on the same amount and in the same manner
        and at the same times as would have been the case if such option had not
        been exercised or (y) an Opinion of Counsel to the same effect as the
        ruling described in clause (x) above and (2) an Opinion of Counsel to
        the effect that (w) the creation of the defeasance trust does not
        violate the Investment Company Act of 1940, (x) the Holders have a valid
        first-priority security interest in the trust funds and (y) after the
        passage of 123 days following the deposit (except, with respect to any
        trust funds for the account of any Holder who may be
 
                                       40

          deemed to be an "insider" for purposes of the United States Bankruptcy
          Code, after one year following the deposit), the trust funds will not
          be subject to the effect of Section 547 of the United States
          Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law
          in a case commenced by or against the Company under either such
          statute, and either (I) the trust funds will not longer remain the
          property of the Company (and therefore will not be subject to the
          effect of any applicable bankruptcy, insolvency, reorganization or
          similar laws affecting creditors' rights generally) or (II) if a court
          were to rule under any such law in any case or proceeding that the
          trust funds remained property of the Company, (a) assuming such trust
          funds remained in the possession of the Trustee prior to such court
          ruling to the extent not paid to the Holders, the Trustee will hold,
          for the benefit of the Holders, a valid and perfected security
          interest in such trust funds that is not avoidable in bankruptcy or
          otherwise except for the effect of Section 552(b) of the United States
          Bankruptcy Code on interest on the trust funds accruing after the
          commencement of a case under such statute and (b) the Holders will be
          entitled to receive adequate protection of their interests in such
          trust funds if such trust funds are used in such case or proceeding;
 
             (d) if the Securities are then listed on a national securities
        exchange, the Company shall have delivered to the Trustee an Opinion of
        Counsel to the effect that such deposit, defeasance and discharge will
        not cause the Securities to be delisted; and
 
             (e) the Company has delivered to the Trustee an Officers'
        Certificate and an Opinion of Counsel, in each case stating that all
        conditions precedent provided for herein relating to the defeasance
        contemplated by this Section 11.1(B) have been complied with.
 
     Notwithstanding the foregoing clause (a), prior to the end of the 123-day
period referenced to in clause (d)(2)(y) above, none of the Company's
obligations under this Indenture shall be discharged. Subsequent to the end of
such 123-day period with respect to this Section 11.1, the Company's obligations
in Sections 2.2, 2.3, 2.4, 2.5, 2.6, 4.1, 4.2, 4.3, 4.4, 8.6, 8.9, 11.2, 11.4
and 11.5 shall survive until the Securities are no longer outstanding.
Thereafter, only the Company's obligations in Section 8.6 and 11.2 shall
survive. If and when a ruling from the Internal Revenue Service or an Opinion of
Counsel referred to in clause (d)(1) above is able to be provided specifically
without regard to, and not in reliance upon, the continuance of the Company's
obligations under Section 4.1, then the Company's obligations under such Section
4.1 shall cease upon delivery to the Trustee of such ruling or Opinion of
Counsel and compliance with the other conditions precedent provided for herein
relating to the defeasance contemplated by this Section 11.1.
 
     After any such irrevocable deposit, the Trustee upon request, shall
acknowledge in writing the discharge of the Company's obligations under the
Securities and this Indenture with respect to the Securities except for those
surviving obligations in the immediately preceding paragraph.
 
          (C) The Company may omit to comply with any term, provision or
     condition set forth in clause (d) of Section 6.1 of this Indenture, the
     covenants described in Sections 4.11, 4.13, 4.14, 4.15 and 4.18 of this
     Indenture and clause (c) of Section 7.1 of this Indenture with respect to
     such covenants, and clauses (d), (e) and (h) of Section 7.1 shall be deemed
     not to be Events of Default, in each case with respect to the outstanding
     Securities if:
 
             (a) with reference to this Section 11.1(C), the Company has
        irrevocably deposited or caused to be irrevocably deposited with the
        Trustee (or another trustee satisfying the requirements of Section 8.8)
        and conveyed in and to all right, title and interest to the Trustee for
        the benefit of the Holders, under the terms of an irrevocable trust
        agreement in form and substance satisfactory to the Trustee as trust
        funds in trust, specifically pledged to the Trustee as security for
        payment of the principal of, premium, if any, and interest, in any, on
        the Securities for, and dedicated solely to, the benefit of the Holders
        of the Securities, in and to (1) money in an amount, (2) U.S. Government
        Obligations that, through the payment of interest and principal in
        respect thereof in accordance with their terms, will provide, not later
        than one day before the due date of any payment referred to in this
        clause (a), money in an amount or (3) a combination thereof in an amount
        sufficient, in the opinion of a nationally recognized firm of
        independent public accountants expressed in a written certification
        thereof delivered to the Trustee, to pay and discharge, without
        consideration of the reinvestment of
 
                                       41
<PAGE>   48
 
          such interest and after payment of all federal, state and local taxes
          or other charges and assessments in respect thereof payable by the
          Trustee, the principal of, premium, if any, and interest on the
          outstanding Securities on the Stated Maturity of such principal or
          interest; provided that the Trustee shall have been irrevocably
          instructed to apply such money or the proceeds of such U.S. Government
          Obligations to the payment of such principal, premium, if any, and
          interest with respect to the Securities;
 
             (b) such deposit will not result in a breach or violation of, or
        constitute a default under, this Indenture or any other agreement or
        instrument to which the Company is a party or by which it is bound;
 
             (c) no Default or Event of Default shall have occurred and be
        continuing on the date of such deposit;
 
             (d) the Company has delivered to the Trustee an Opinion of Counsel
        to the effect that (1) the creation of the defeasance trust does not
        violate the Investment Company Act of 1940, (2) the Holders of the
        Securities have a valid first-priority security interest in the trust
        funds, (3) the Holders will not recognize income, gain or loss for
        federal income tax purposes as a result of such deposit and defeasance
        of certain obligations and will be subject to federal income tax on the
        same amount and in the same manner and at the same times as would have
        been the case if such deposit and defeasance had not occurred and (4)
        after the passage of 123 days following the deposit (except, with
        respect to any trust funds for the account of any Holder who may be
        deemed to be an "insider" for purposes of the United States Bankruptcy
        Code, after one year following the deposit), the trust funds will not be
        subject to the effect of Section 547 of the United States Bankruptcy
        Code or Section 15 of the New York Debtor and Creditor Law in a case
        commenced by or against the Company under either such statute, and
        either (x) the trust funds will no longer remain the property of the
        Company (and therefore will not be subject to the effect of any
        applicable bankruptcy, insolvency, reorganization or similar laws
        affecting creditors' rights generally) or (y) if a court were to rule
        under any such law in any case or proceeding that the trust funds
        remained property of the Company, and (i) assuming such trust funds
        remained in the possession of the Trustee prior to such court ruling to
        the extent not paid to the Holders the Trustee will hold, for the
        benefit of the Holders, a valid and perfected security interest in such
        trustee funds that is not avoidable in bankruptcy or otherwise except
        for the effect of Section 552(b) of the United States Bankruptcy Code on
        interest on the trust funds accruing after the commencement of a case
        under such statute and (ii) the Holders will be entitled to receive
        adequate protection of their interests in such trust funds if such trust
        funds are used in such case or proceeding;
 
             (e) if the Securities are then listed on a national securities
        exchange, the Company shall have delivered to the Trustee an Opinion of
        Counsel to the effect that such deposit, defeasance and discharge will
        not cause the Securities to be delisted; and
 
             (f) the Company has delivered to the Trustee an Officers'
        Certificate and an Opinion of Counsel, in each case stating that all
        conditions precedent provided for herein relating to the defeasance
        contemplated by this Section 11.1 have been complied with.

Paying Agent (including the Company or the guarantor acting as Paying Agent), to
the Holders of the Securities for the payment or redemption of which such monies
have been deposited with the Trustee, of all sums due and to become due thereon
for principal premium, if any, and interest if may; but such money need not be
segregated from other funds except to the extent required by law.
 
     If the Trustee or any Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with Section 11.1 by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such applications, the
 
                                       42
<PAGE>   49
 
Company's obligations under this Indenture and the Securities related thereto
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 11.1B(a) or 11.1C(a) until such time as the Trustee or any Paying Agent
is permitted to apply all such money or U.S, Government Obligations in
accordance with Section 11.1; provided, however, that if the Company has made
any payment of interest on or principal of and premium (if any) on the
Securities because of the reinstatement of its obligations hereunder, the
Company shall be subrogated to the rights of the holders of the Securities to
receive such payment from the money or U.S. Government obligations held by the
Trustee for such purpose.
 
     SECTION 11.3  Repayment of Monies Held by Paying Agent.  In connection with
the satisfaction and discharge of this Indenture with respect to Securities, all
monies then held by any Paying Agent under the provisions of this Indenture with

Company or paid to the Trustee and thereupon such Paying Agent shall be released
from all further liability with respect to such monies.

upon which such principal or interest shall have become due and payable shall,
upon the written request of the Company and unless otherwise required by
mandatory provisions of applicable escheat or abandoned or unclaimed property
law, be repaid to the Company by the Trustee or such Paying Agent, and the
Holder of the Securities shall, unless otherwise required by mandatory
provisions of applicable escheat or abandoned or unclaimed property laws,
thereafter look only to the Company for any payment that such Holder may be
entitled to collect, and all liability of the Trustee or any Paying Agent with
respect to such monies shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment
with respect to monies deposited with it for any payment, may at the expense of
the Company, mail by first-class mail to Holders of such Securities at their
addresses as they shall appear on the security register notice, that such monies
remain and that, after a date specified therein, which shall not be less than
thirty days from the date of such mailing, any unclaimed balance of such money
then remaining will be, repaid to the Company.
 
     SECTION 11.5  Indemnity for U.S. Government Obligations.  The Company shall
pay and indemnify the Trustee against any tax, fee or other charge imposed on or
assessed against the U.S. Government Obligations deposited by the Company

incorporator or shareholder of the Company or the Trustee shall have any
liability for any obligation of the Company under this Indenture or the
Securities or for any claim based on, in respect of, or by reason of, any such
obligation or the creation of any such obligation. Each Holder by accepting a
Security waives and releases such Persons from all such liability and such
waiver and release is part of the consideration for the issuance of the
Securities.
 
     SECTION 12.2  Provisions of Indenture for the Sole Benefit of Parties and
Holders of Securities. Nothing in this Indenture or in the Securities expressed
or implied, shall give or be construed to give to any person, firm or

Indenture or under any covenant or provision herein contained, all such
covenants and provisions being for the sole benefit of the parties hereto and
their successors and of the Holders of the Securities.

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

in this Indenture shall include (a) a statement that the person making such
certificate or opinion has read such covenant or condition, (b) a brief
statement as to the nature and scope of the examination or investigation upon
which the statements or opinions contained in such certificate or opinion are
based, (c) a statement that, in the opinion of such person, he has made such
examination or investigation as is necessary to enable him to express an
informed opinion as to whether or not such covenant or condition has been
complied with and (d) a statement as to whether or not, in the opinion of such
person, such condition or covenant has been complied with.
 
     Any certificate, statement or opinion of an officer of the Company may be

or representations by counsel, unless such officer knows that the certificate or
opinion or representations with respect to the matters upon which his
certificate, statement or opinion may be based as aforesaid are erroneous, or in
the exercise of reasonable care should know that the same are erroneous. Any
certificate, statement or opinion of counsel may be based, insofar as it relates
to factual matters, information with respect to which is in the possession of
the Company, upon the certificate, statement or opinion of or representations by
an officer or officers of the Company unless such counsel knows that the
certificate, statement or opinion or representations with respect to the matters
upon which his certificate, statement or opinion may be based as aforesaid are
erroneous, or in the exercise of reasonable care should know that the same are
erroneous.
 
     Any certificate, statement or opinion of an officer of the Company or of
counsel may be based, insofar as it relates to accounting matters, upon a
certificate or opinion of or representations by an accountant or firm of
accountants in the employ of the Company, unless such officer or counsel, as the
case may be, knows that the certificate or opinion or representations with
respect to the accounting matters upon which his certificate, statement or
opinion may be based as aforesaid are erroneous, or in the exercise of
reasonable care should know that the same are erroneous.

filed with and directed to the Trustee shall contain a statement that such firm
is independent.

     SECTION 12.6  Payments Due on Saturdays, Sundays and Holidays.  If the date
of maturity of interest on or principal of the Securities the date fixed for
redemption or repayment of any Security shall not be a Business Day, then

the date of maturity or the date fixed for redemption, and no interest shall
accrue for the period after such date.

Act of 1939.  If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with the duties imposed by, or with another provision (an
"incorporated provision") included in this Indenture by operation of, Sections
310 to 316, inclusive, of the Trust Indenture Act of 1939, such imposed duties
or incorporated provision shall control.

                        % SENIOR UNSECURED NOTES DUE 2001
 
1. INTEREST.
 
     America West Airlines, Inc., a Delaware corporation (the "Company"),
promises to pay interest on the unpaid principal amount of this Security to
Persons who are registered Holders at the close of business on the relevant
Record Date at the rate of    % per annum.
 
     Interest shall be computed on the basis of a 360-day year of twelve 30-day
months and shall be payable semi-annually on                15 and
               15 of each year commencing                15, 1994, or if any
such day is not a Business Day, on the next succeeding Business Day. Interest
will accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the date of issuance. Interest shall accrue with
respect to principal on this Security to, but not including the date of
repayment of such principal; provided, however, that if payment to the Paying
Agent occurs after 10:00 a.m., New York City time, interest shall be deemed to
accrue until the following Business Day.
 
     To the extent lawful, the Company shall pay interest on overdue principal,
premium (if any) and interest at the rate of interest borne by this Security. On
each Interest Payment Date, interest on the Securities will be paid for the
immediately preceding accrual period.
 
2. METHOD OF PAYMENT.
 
     The Company will pay interest on the Securities (except defaulted interest)
to the persons who are registered Holders at the close of business on the Record
Date next preceding the applicable Interest Payment Date. If the Company
defaults in the payment of the interest due on such Interest Payment Date, such
defaulted interest will be paid to the Persons who are registered Holders of
Securities at the close of business on a subsequent record date established by
notice given not less than 15 days prior to such subsequent record date. The
Company will pay the principal of this Security to the Holder that surrenders
this Security to a Paying Agent on or after                , 2001 or, in the
event of a redemption of this Security, on or after the Redemption Date, as
described below. The Company will pay principal and interest in U.S. Legal
Tender by Federal funds bank wire transfer or (in the case of payment of
interest) by check. If this Security is a Global Security, all payments in
respect of this Security will be made to the Depository or its nominee in
immediately available funds in accordance with customary procedures established
from time to time by the Depository.
 
3. PAYING AGENT AND REGISTRAR.
 
     Initially,                (the "Trustee"), will act as Paying Agent and
registrar for the Securities. The Company may change any Paying Agent, co-Paying
Agent, registrar or co-registrar without notice. Except as provided in the
Indenture, the Company or any of its Subsidiaries may, subject to certain
exceptions, act as Paying Agent, registrar or co-registrar.
 
4. INDENTURE.
 
     The Company issued this Security under an Indenture dated as of
               , 1994 (the "Indenture") between the Company and the Trustee.

Indenture and those made part of the Indenture by reference to the Trust

are subject to all such terms, and Holders of the Securities are referred to the
Indenture and said Act for a statement of such terms. In the event of any
conflict between this Security and the Indenture, the Indenture shall govern.
The Securities are general unsecured obligations of the Company limited in
aggregate principal amount to $100,000,000.

8. DENOMINATIONS; TRANSFER; EXCHANGE.
 
     The Securities are in fully registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000. A Holder may register

     In accordance with the provisions of the Indenture and subject to certain
limitations therein set forth, an owner of a beneficial interest in a Global
Security may request a Security in certificated form, in exchange in whole or in

Securities in authorized denominations equal in principal amount to such
beneficial interest and to have such Securities registered in its name.

demand, authorization, direction, notice, consent, waiver or other action which
a Holder of a Security is entitled to give or take under the Indenture.

payment of principal, premium (if any) or interest on the Securities remains

back to the Company at its request. After that, all liability of the Trustee and
such Paying Agent with respect to such money shall cease.
 
11. DISCHARGE PRIOR TO REDEMPTION OR MATURITY.
 
     If the Company at any time deposits with the Trustee money or U.S.
Government Obligations sufficient to pay the principal of and interest on the
Securities to redemption or maturity and complies with the other provisions of
the Indenture relating thereto, the Company will be discharged from certain
provisions of the Indenture and the Securities (including the financial
covenants, but excluding certain obligations, including without limitation its
obligation to pay the principal of or interest on the Securities).
 
12. AMENDMENT; SUPPLEMENT; WAIVER.
 
     Subject to certain exceptions, the Indenture or the Securities may be
amended or supplemented with the consent of the Holders of at least a majority

with the consent of the Holders of at least a majority in aggregate principal
amount of the outstanding Securities. Without notice to or consent of any
Holder, the parties thereto may amend or supplement the Indenture or the
Securities to, among other things, cure any ambiguity, correct or supplement any
provision which may be inconsistent with any other provision, or to make any
other provisions with respect to matters or questions arising under the
Indenture which shall not be inconsistent with the provisions of the Indenture
(provided such amendment or supplement does not adversely affect the rights of
any of the Holders), provide for any additional rights or benefits to Holders or
make any change that does not adversely affect the rights of any Holder.
 
13. RESTRICTIVE COVENANTS.

of its Securities at its discretion by completing the form entitled "Option of
Holder to Elect Purchase" appearing on the reverse side of this Security.

exceptions, the Trustee or the Holders of at least 25% in principal amount of
Securities may declare all the Securities to be due and payable immediately in
the manner and with the effect provided in the Indenture. Holders of Securities
may not enforce the Indenture or the Securities except as provided in the
Indenture. The Trustee may require indemnity satisfactory to it before it
enforces the Indenture or the Securities. Subject to certain limitations,
Holders of a majority in principal amount of the Securities then outstanding may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold notice in certain circumstances.

present or future, of the Company or any successor corporation shall have any
liability for any obligation of the Company under the Securities or the
Indenture or for any claim based on, in respect of or by reason of, such
obligations or their creation. Each Holder of a Security by accepting a Security
waives and releases all such liability. The waiver and release are part of the
consideration of the issue for the Securities.

            ISSUANCE, EXECUTION AND TRANSFER OF WARRANT CERTIFICATES
 
     SECTION 2.01.  Form of Warrant Certificates.  The Warrants shall be
evidenced by certificates in temporary or definitive fully registered form (the
"Warrant Certificates" ) substantially in the form of Exhibit A hereto, and
designated as Warrants to Purchase Class B Common Stock of America West
Airlines, Inc., and may have such letters, numbers or other marks of
identification and such legends or endorsements placed thereon as may be
required to comply with any law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any securities exchange, or to conform
to usage, or as may, consistently herewith, be determined to be necessary or
appropriate by the officers of the Company executing such Warrant Certificates
as evidenced by their execution of the Warrant Certificates. Each Warrant shall
evidence the right, subject to the provisions of this Agreement and of the
Warrant Certificate, to purchase one share of Class B Common Stock at the

     SECTION 2.02.  Execution of Warrant Certificates.  Each Warrant

be valid for any purpose unless so countersigned. Warrant Certificates may be
countersigned by the Warrant Agent, with the same effect, notwithstanding that
any Persons whose manual or facsimile signatures appear thereon as proper
officers of the Company shall have ceased to be such officers at the time of
such countersignature. Any Warrant Certificate may be signed on behalf of the
Company by any Person who, at the actual date of the execution of such Warrant
Certificate, shall be a proper officer of the Company to sign such Warrant
Certificate, although at the date of the execution of this Agreement any such
Person was not such an officer.
 
     SECTION 2.03.  Issuance, Delivery and Registration of Warrant
Certificates.  The Warrant Agent shall, and the Company shall cause the Warrant
Agent to, countersign, issue and deliver:

     Certificates representing 2,769,231 Warrants;
 
          (b) to [the Equity Holders/the Trust as provided for in the Plan], on
     the Distribution Date, Warrant Certificates representing 6,230,769
     Warrants;

     shall countersign and deliver Warrant Certificates upon exchange or
     transfer of or substitution for, one or more previously countersigned
     Warrant Certificates as hereinafter provided. The Warrant Agent shall
     maintain books (the "Warrant Register" ) for the registration of Warrant
     Certificates (including, without limitation, registration of the Warrant
     Certificates described above) and the registration of transfers of Warrant
     Certificates after the Distribution Date.
 
     SECTION 2.04.  Transfer and Exchange of Warrant Certificates.
 
          (a) Notwithstanding anything herein to the contrary, neither any
     Warrant nor the Class B Common Stock underlying any Warrant may be sold,
     assigned or otherwise transferred to any Person unless such transfer is
     made pursuant to an effective registration statement or otherwise in
     accordance with the
 
                                        3
<PAGE>   7
 
     requirements of the 1933 Act and applicable state securities laws. Until
     the Restricted Securities cease to be Restricted Securities, certificates
     evidencing Restricted Securities (and only such certificates) will bear a
     legend in substantially the following form:
 
          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND THE RULES AND
     REGULATIONS THEREUNDER (THE "1933 ACT" ) OR UNDER 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 OR AN
     EXEMPTION THEREFROM AND FROM ANY APPLICABLE STATE SECURITIES LAWS.
 
     During such period, the Company may instruct its transfer agent to mark its
records to restrict the transfer of Restricted Securities.
 
     For purposes of this Agreement, the term "Restricted Securities" shall mean
the Warrants issued to AmWest[, GPA] or any of their respective Affiliates or
assignees on the Distribution Date and (a) any shares of Class B Common Stock
which have been issued upon exercise of such Warrants and (b) any shares of
Class B Common Stock which are issuable upon the exercise of such Warrants. For
the purposes of this Agreement, such securities will cease to be Restricted
Securities (i) when they have been sold pursuant to an effective registration
statement under the 1933 Act, (ii) when they are distributed to the public
pursuant to Rule 144 (or any similar provision then in force) under the 1933 Act
or (iii) when (A) they have been otherwise transferred without registration
under the 1933 Act pursuant to an exemption from the registration requirements
of the 1933 Act and (B) if it has so requested, the Company has received an
opinion of counsel (either its own counsel or, if the Company so requests,
counsel to the holders of such Restricted Securities) acceptable to the Company
that such Restricted Securities may be so transferred without registration or
pursuant to an exemption, and in each such instance has delivered new
certificates or other evidence of ownership for such securities that are not
subject to any stop transfer order or other restriction on transfer and not
bearing the legend prescribed by the preceding paragraph.
 
          (b) Subject to paragraph (a) above, the Warrant Agent, from time to
     time, shall register the transfer of all or any whole number of Warrants
     covered by any outstanding Warrant Certificates in the Warrant Register
     upon surrender at the Warrant Agent's Office of Warrant Certificates
     accompanied by a written instrument or instruments of transfer, in form
     satisfactory to the Company and the Warrant Agent, duly executed by the
     registered Warrant holder or his attorney duly authorized in writing. Upon
     any such registration of transfer, a new Warrant Certificate shall be
     countersigned by the Warrant Agent and issued to the transferee and the
     surrendered Warrant Certificate shall promptly be canceled by the Warrant
     Agent. Warrant Certificates may be exchanged at the option of the holder
     thereof, upon surrender, properly endorsed, at the Warrant Agent's Office,
     with written instructions, for other Warrant Certificates countersigned by
     the Warrant Agent representing in the aggregate a like number of Warrants.
     The Company or the Warrant Agent may require the payment of a sum
     sufficient to cover any tax or governmental charge that may be imposed in
     connection with any such exchange or transfer.
 
                                  ARTICLE III
            WARRANT PRICE, EXPIRATION DATE AND EXERCISE OF WARRANTS
 
     SECTION 3.01.  Warrant Price; Expiration Date.  Each Warrant Certificate
shall entitle the registered holder thereof, subject to the provisions thereof
and of this Agreement, to purchase from the Company at any time commencing at
the opening of business on the day after the Distribution Date and before 5:00
p.m., New York time, on the Expiration Date, one share of Class B Common Stock
for each of the Warrants specified therein, at the Warrant Price, subject to
adjustment as provided in Article IV hereof, payable in full at the time of
purchase. Each Warrant not exercised during the applicable period set forth
above shall become void, and all rights thereunder and all rights in respect
thereof under this Agreement shall cease at the end of such period.

<PAGE>   8
 
     SECTION 3.02.  Exercise of Warrants; Common Stock Record Date.
 
          (a) Commencing at the opening of business on the day after the
     Distribution Date, Warrants may be exercised by surrendering the Warrant
     Certificate evidencing such Warrants at the Warrant Agent's Office with the
     Election to Exercise form set forth on the reverse of the Warrant
     Certificate duly completed and executed by the registered holder thereof or
     his attorney duly authorized in writing, and by paying in full to the
     Warrant Agent for the account of the Company (i) in cash, (ii) by certified
     or official bank check or (iii) by any combination of the foregoing, the
     Warrant Price for each share of Class B Common Stock as to which Warrants
     are exercised and any applicable taxes that the Company is not required to
     pay as set forth in Section 4.08 or 6.01. A registered Warrant holder may
     exercise all or any number of whole Warrants represented by a Warrant
     Certificate. [In the alternative, the registered holder of a Warrant
     Certificate may exercise its rights to purchase some or all of the shares
     of Class B Common Stock represented by such Warrant Certificate on a net
     basis such that, without the exchange of any funds, such holder receives
     that number of shares of Class B Common Stock subscribed to pursuant to
     such Warrant Certificate less that number of shares of Class B Common Stock
     having an aggregate current market price per share, as computed pursuant to
     Section 4.01(d) hereof, at the time of exercise equal to the sum of (i) the
     aggregate Warrant Price for such shares subscribed to pursuant to such
     Warrant Certificate and (ii) any applicable taxes that the Company is not
     required to pay as set forth in Section 4.08 or 6.01 (unless such holder
     has otherwise paid to the Warrant Agent in cash or by certified bank check
     the amount of such taxes).]
 
          (b) Subject to the provisions of subsection (e) below and Section 4.08
     hereof, as soon as practicable (and in any event within five (5) Business
     Days) after the exercise of any Warrants and payment [, if applicable,] by
     the registered Warrant holder of the full Warrant Price for the shares as
     to which such Warrants are then being exercised, the Warrant Agent shall
     promptly requisition from the transfer agent of the Class B Common Stock
     and deliver to or upon the order of such registered Warrant holder a
     certificate or certificates for the number of full shares of Class B Common
     Stock to which such Warrant holder is entitled, registered in such name or
     names as may be directed by him (if other than to such registered holder,
     (i) to the extent such transfer is not validly restricted and (ii) upon
     payment of any transfer taxes that are required to be paid by such holder
     or its transferees in connection with any transfer by such registered
     holder), together with cash or scrip, as provided in Section 3.03 hereof,
     in respect of any fractional shares, and, if the number of Warrants
     represented by a Warrant Certificate shall not have been exercised in full,
     a new Warrant Certificate delivered to the holder of the Warrant
     Certificate or to his duly authorized assignee, countersigned by the
     Warrant Agent, for the number of Warrants remaining unexercised, together
     with cash or scrip, as provided in Section 4.04 hereof, in respect of the
     balance of any fractional Warrants represented by the surrendered Warrant
     Certificate. Any shares of Class B Common Stock issued upon a Warrant
     holder's exercise of any Warrant shall be validly authorized and issued,
     fully paid, non-assessable, free of pre-emptive rights and free from all
     taxes (other than those specified in clause (ii) above), liens, charges,
     security interests and claims created or incurred by the Company in respect
     of the issuance thereof.
 
          (c) A Warrant shall be deemed to have been exercised immediately prior
     to the close of business on the date of the due surrender for exercise of
     the Warrant Certificate and payment [, if applicable,] to the Warrant Agent
     for the account of the Company of the Warrant Price and any applicable
     taxes that the Company is not required to pay as set forth in Section 4.08
     or 6.01. Each Person in whose name any such certificate for shares of Class
     B Common Stock is issued shall for all purposes be deemed to have become
     the holder of record of such shares at the close of business on the date on
     which the Warrant Certificate was duly surrendered to the Warrant Agent and
     payment of the Warrant Price and any such applicable taxes was made to the
     Warrant Agent for the account of the Company, irrespective of the date of
     delivery of such share certificate, except that, if the date of such
     surrender and payment is a date when the stock transfer books of the
     Company are closed, such Person shall be deemed to have become the holder
     of such shares at the close of business on the next succeeding date on
     which the stock transfer books are open (whether before or after the
     Expiration Date).
 
                                        5
<PAGE>   9
 
          (d) The Warrant Agent shall promptly notify both the Company and the
     transfer agent of the Class B Common Stock in writing of any exercise of
     any Warrant and of the number of shares delivered upon the exercise of such
     Warrant and shall pay to the Company within 72 hours after receipt by wire
     transfer or certified or official bank check payable to the order of the
     Company the amount of money received by it upon the exercise of Warrants
     (less any amount paid by the Warrant Agent in respect of a fractional share
     upon such exercise in accordance with Section 3.03 hereof). The Warrant
     Agent shall hold any proceeds collected and not yet paid to the Company in
     a federally insured escrow account. A detailed accounting statement setting
     forth the number of Warrants exercised, the amount of funds received
     [and/or Warrants surrendered] upon such exercise and all expenses incurred
     by the Warrant Agent as provided in this Agreement shall be transmitted to
     the Company on payment to the Company of the funds so received [(or upon
     the receipt of the Warrants so surrendered)] upon exercise. The Warrant
     Agent shall render to the Company a complete accounting setting forth the
     number of Warrants exercised [and surrendered], the identity of the Persons
     exercising such Warrants, the number of shares issued, the amounts
     distributed to the Company and all expenses incurred by the Warrant Agent
     as provided in this Agreement as of the Expiration Date.
 
          (e) The Warrant Agent may deem and treat the Person named as the
     registered holder on the face of any Warrant as the true and lawful owner
     thereof for all purposes. If the Warrant Agent is instructed to deliver
     shares upon the exercise of Warrants or to deliver a Warrant Certificate
     representing unexercised Warrants, in either case registered in a name or
     names other than the name or names in which a Warrant Certificate tendered
     in connection with such exercise is registered, the Warrant Agent may
     require such documents, and such evidence of payment of applicable transfer
     taxes, as it may deem necessary to enable it to carry out the instructions
     of the bearer.
 
     SECTION 3.03.  No Fractional Shares to Be Issued.  Notwithstanding anything
to the contrary contained in this Agreement, if the number of shares of Class B
Common Stock purchasable on the exercise of each Warrant is adjusted pursuant to
the provisions of Section 4.02 hereof, the Company shall not be required to
issue any fraction of a share of Class B Common Stock or to distribute stock
certificates that evidence fractional shares of Class B Common Stock. If Warrant
Certificates evidencing more than one Warrant shall be surrendered for exercise
at one time by the same holder, the number of full shares which shall be
issuable upon exercise thereof shall be computed on the basis of the aggregate
number of Warrants so surrendered. If any fraction of a share of Class B Common
Stock would, except for the provisions of this Section 3.03, be issuable on the
exercise of any Warrant or Warrants, the Company shall, at its option upon
notice to the Warrant Agent given within two (2) Business Days of exercise of
any such Warrant or Warrants, either (a) purchase such fraction for an amount in
cash equal to the then-current market value of such fraction computed in
accordance with Section 4.01(d) hereof (assuming, for the purpose of such
computation, that the date of surrender of such Warrants to the Warrant Agent
shall be the applicable record date referred to in Section 4.01(d)) or (b) issue
scrip of the Company in lieu thereof, rounded up to the nearest one-hundredth of
a share. Such scrip shall be non-dividend bearing and non-voting, shall be
exchangeable in combination with other similar scrip for the number of full
shares of Class B Common Stock represented thereby, shall be issued in such
denominations (not less than one-hundredth of a share) and in such form, shall
expire after such reasonable time (which shall not be sooner than either (i)
five years from the date of issue or (ii) one year after the Expiration Date,
whichever first occurs) and may contain such provisions for sale for the account
of the holders of such scrip of shares of Class B Common Stock for which such
scrip is exchangeable or the payment to such holders of the market value of such
shares, and be subject to such other terms and provisions, if any, as the Board
of Directors may from time to time determine. The Warrant holders, by their
acceptance of the Warrant Certificates, expressly waive their right to receive
any fraction of a share of Class B Common Stock or a stock certificate
representing a fraction of a share of Class B Common Stock.
 
     SECTION 3.04.  Acquisition of Warrants by the Company; Cancellation of
Warrants.  The Company shall have the right, except as limited by law or other
agreement, to purchase or otherwise acquire Warrants at such times, in such
manner and for such consideration as it may deem appropriate. The Warrant Agent
shall cancel any Warrant Certificate delivered to it for exercise, in whole or
in part, or delivered to it for transfer, exchange, or substitution, and no
Warrant Certificates shall be issued in lieu thereof unless such exercise,
 
                                        6
<PAGE>   10
 
transfer, exchange or substitution is expressly permitted by the provisions of
this Agreement. On request of the Company, the Warrant Agent shall destroy
canceled Warrant Certificates held by it and shall deliver its certificates of
destruction to the Company. If the Company shall acquire any of the Warrants,
such acquisition shall not operate as a redemption or termination of the right
represented by such Warrants unless and until the Warrant Certificates
evidencing such Warrants are surrendered to the Warrant Agent for cancellation.
 
                                   ARTICLE IV
 
                 ADJUSTMENT OF WARRANT PRICE, SHARES OF COMMON
                    STOCK PURCHASABLE AND NUMBER OF WARRANTS
 
     SECTION 4.01.  Adjustment of Warrant Price.  The Warrant Price specified in
Section 3.01 shall be subject to adjustment from time to time as follows:
 
          (a) If the Company after the date hereof shall (i) pay a dividend or
     make a distribution to all holders of Common Stock or any class thereof in
     shares of Common Stock or any class thereof, (ii) subdivide the outstanding
     shares of Common Stock or any class thereof, or (iii) combine the
     outstanding shares of Common Stock or any class thereof into a smaller
     number of shares, then in any such case the Warrant Price in effect
     immediately prior thereto shall be adjusted to a price obtained by
     multiplying such Warrant Price by a fraction of which the numerator shall
     be the number of shares of Common Stock outstanding prior to such action
     and the denominator shall be the number of shares of Common Stock
     outstanding after giving effect to such action. An adjustment made pursuant
     to clause (i) of this subsection (a) shall become effective retroactively
     immediately after the record date for such dividend or distribution, and an
     adjustment made pursuant to clause (ii) or (iii) of this subsection (a)
     shall become effective immediately after the effective date of such
     subdivision or combination.
 
          (b) If the Company after the date hereof shall issue rights or
     warrants to all holders of Common Stock or any class thereof entitling them
     [for a period expiring within 45 days after the record date mentioned
     below] to subscribe for or purchase shares of Common Stock or any class
     thereof at a price per share less than the then-current market price per
     share (as determined pursuant to subsection (d) below) on the record date
     (or, if applicable, the ex-distribution date) mentioned below, the Warrant
     Price in effect immediately prior thereto shall be adjusted to a price
     obtained by multiplying such Warrant Price by a fraction of which (i) the
     numerator shall be the number of shares of Common Stock outstanding on the
     date of issuance of such rights or warrants plus the number of shares of
     Common Stock of the class subject to such rights or warrants which the
     aggregate offering price of the total number of shares so to be offered
     would purchase at the current market price of the Common Stock subject to
     such rights or warrants, and (ii) the denominator shall be the number of
     shares of Common Stock outstanding on the date of issuance of such rights
     or warrants plus the number of additional shares of Common Stock, or the
     applicable class thereof, to be offered for subscription or purchase;
     provided, however, that no adjustment shall be made if the Company issues
     or distributes to each holder of Warrants the rights or warrants which each
     holder of Warrants would have been entitled to receive had such Warrants
     been exercised prior to the record date mentioned below. Any such
     adjustments shall be made whenever such rights or warrants are issued and
     shall become effective retroactively immediately after the record date for
     the determination of stockholders entitled to receive such rights or
     warrants. [Upon expiration of the period during which any such rights or
     warrants may be exercised, any adjustment previously made pursuant to the
     foregoing provisions shall be recalculated to take into consideration only
     those rights or warrants actually exercised during the applicable period
     for exercise and notice of any such further adjustment to the Warrant Price
     shall be given to Warrant holders as herein provided.]
 
          (c) If the Company after the date hereof shall issue or distribute to
     all holders of Common Stock or any class thereof evidences of its
     indebtedness or assets (excluding any cash dividend or distribution),
     shares of capital stock of any class other than the Common Stock or rights
     to subscribe therefor (excluding those referred to in subsection (b)
     above), in each such case the Warrant Price in effect immediately prior
     thereto shall be adjusted to a price obtained by multiplying such Warrant
     Price by a
 
                                        7
<PAGE>   11
 
     fraction of which (i) the numerator shall be the sum of the amount, for
     each class of Common Stock then outstanding, of the then-current market
     price per share (determined as provided in subsection (d) below) of the
     Common Stock of such class, multiplied by the number of outstanding shares
     of such class, in each case on the record date (or, if applicable, the
     ex-distribution date) mentioned below less the then-current fair market
     value (as determined by the Board of Directors in its reasonable judgment
     whose determination shall be conclusive, and described in a statement filed
     with the Warrant Agent) of the assets or evidences of indebtedness so
     distributed, such shares of capital stock of any class other than Common
     Stock or rights to subscribe therefor, and (ii) the denominator shall be
     the sum of the amount, for each class of Common Stock then outstanding, of
     the then-current market price per share of the Common Stock of such class,
     multiplied by the number of outstanding shares of such class, in each case
     on the record date (or, if applicable, the ex-distribution date) mentioned
     below; provided, however, that no adjustment shall be made (1) if the
     Company issues or distributes to each holder of Warrants the subscription
     rights referred to above in this subsection (c) that each holder of
     Warrants would have been entitled to receive had the Warrants been
     exercised prior to the record date mentioned below, or (2) if the Company
     grants to each holder of Warrants the right to receive, upon the exercise
     thereof at any time after the distribution of the evidences of indebtedness
     or assets or shares of capital stock of any class other than the Common
     Stock referred to above in this subsection (c), the evidences of
     indebtedness or assets or shares of capital stock of any class other than
     the Common Stock that such holder would have been entitled to receive had
     the Warrants been exercised prior to the record date mentioned below. The
     Company shall provide the Warrant Agent, upon receipt of a written request
     therefor, with any indenture or other instrument defining the rights of the
     holders of any indebtedness, assets, capital stock or subscription rights
     referred to in this subsection 4.01(c). Any such adjustment shall be made
     whenever any such distribution is made and shall become effective
     retroactively immediately after the record date for the determination of
     stockholders entitled to receive such distribution. [Upon expiration of the
     period during which any subscription rights granted pursuant to this
     subsection (c) may be exercised, any adjustment previously made pursuant to
     the foregoing provisions shall be recalculated to take into consideration
     only those subscription rights actually exercised during the applicable
     period for exercise and notice of any such further adjustment to the
     Warrant Price shall be given to Warrant holders as herein provided.]
 
          (d) For the purpose of any computation under subsection (b) or (c)
     above, the current market price per share of any class of Common Stock on
     any date shall be deemed to be the average of the daily mean between the
     high and low sales prices regular way of the shares of such class of Common
     Stock on the exchange on which such shares are listed as specified below
     for the ten consecutive trading days (as defined below) preceding the
     applicable record date (or, if earlier, the date on which such class of
     Common Stock commences trading on an ex-distribution basis). If there shall
     not have been a sale regular way on any such trading day, the mean of the
     last reported bid and asked quotations regular way on the specified
     exchange on such day shall be deemed to be the only sale price. The
     exchange specified for purposes of this subsection 4.01(d) shall be the
     [New York Stock Exchange, Inc.] if the shares of the applicable class of
     Common Stock are listed thereon or, if the shares of the applicable class
     of Common Stock shall not be listed on such exchange, then that national
     securities exchange on which the applicable class of Common Stock is listed
     having the largest volume of trading in the applicable class of Common
     Stock during the calendar year or portion thereof next preceding such
     computation. If the shares of the applicable class of Common Stock shall
     not be listed on any such exchange on all such ten trading days, the
     average of the closing high bid and low asked prices for the applicable
     class of Common Stock in the over-the-counter market on each trading day on
     which such shares are not so listed as reported by the National Association
     of Securities Dealers Automatic Quotation System or, if not so reported,
     then as reported by the National Quotation Bureau Incorporated, or if such
     organization is not in existence, by an organization providing similar
     services (as determined by the Board of Directors of the Company), shall be
     deemed to be the only sale price on such trading day. If the shares of the
     applicable class of Common Stock shall not be so reported on any of such
     trading days, then the current market price per share of such shares of
     Common Stock shall be the fair market value thereof as determined in the
     reasonable judgement of the Board of Directors. For the purpose of this
     subsection 4.01(d), "trading day" shall
 
                                        8
<PAGE>   12
 
     mean a day on which the securities exchange specified for purposes of this
     subsection 4.01(d) shall be open for business or, if the shares of the
     applicable class of Common Stock shall not be listed on such exchange for
     such period, a day with respect to which quotations of the character
     specified for purposes of this subsection 4.01(d) shall be reported.
 
          (e) In any case in which this Section 4.01 shall require that an
     adjustment be made retroactively immediately following a record date, the
     Company may elect to defer (but only until five Business Days following the
     filing by the Company with the Warrant Agent of a certificate signed by the
     Chairman of the Board, Chief Executive Officer, the President or any Vice
     President of the Company (an "Officers' Certificate" ) [or a certificate of
     a firm of independent public accountants] as required in subsection (g) of
     this Section 4.01) issuing to the holder of any Warrant exercised after
     such record date the shares of Class B Common Stock issuable upon such
     exercise in excess of the shares of Class B Common Stock issuable upon such
     exercise prior to such adjustment.
 
          (f) No adjustment shall be required unless such adjustment would
     require an increase or decrease of at least $[0.05] in the Warrant Price
     then subject to adjustment; provided, however, that any adjustments that
     are not made by reason of this subsection (f) shall be carried forward and
     taken into account in any subsequent adjustment. In case the Company shall
     at any time issue Common Stock or any class thereof by way of dividend on
     any stock of the Company or subdivide or combine the outstanding shares of
     Common Stock or any class thereof, said amount of $[0.05] specified in the
     preceding sentence (as theretofore increased or decreased, if said amount
     shall have been adjusted in accordance with the provisions of this
     paragraph (f)) shall forthwith be proportionately increased in the case of
     such a combination or decreased in the case of such a subdivision or stock
     dividend so as appropriately to reflect the same. All calculations under
     this Section 4.01 shall be made to the nearest hundredth of a cent.
 
          (g) Whenever an adjustment in the Warrant Price is made as required or
     permitted by the provisions of Section 4.01, 4.02 or 4.03 of this
     Agreement, the Company shall promptly file with the Warrant Agent [(i)] an
     Officers' Certificate [in the case of an adjustment pursuant to subsection
     (a) or (i) of this Section 4.01, or (ii) a certificate of a firm of
     independent public accountants in the case of any other adjustment pursuant
     to this Section 4.01, in each case] (A) setting forth the adjusted Warrant
     Price as provided in this Section 4.01 and setting forth a brief statement
     of the facts requiring such adjustment and the computation thereof, and (B)
     setting forth the number of shares of Class B Common Stock (or portions
     thereof) purchasable upon exercise of a Warrant after such adjustment in
     the Warrant Price in accordance with Section 4.02 hereof or the number of
     Warrants outstanding in accordance with Section 4.03 hereof after such
     adjustment in the Warrant Price and the record date therefor, which
     Officers' Certificate [or certificate of a firm of independent public
     accountants, as the case may be,] shall be conclusive evidence (absent
     manifest error) of the correctness of any such adjustment, and promptly
     after such filing shall mail or cause to be mailed a notice of such
     adjustment to each Warrant holder at his last address as the same appears
     on the Warrant Register. The Warrant Agent shall be under no duty or
     responsibility with respect to any such certificate except to exhibit the
     same to any holder of Warrants desiring inspection thereof.
 
          (h) In case:
 
             (1) the Company shall declare a dividend (or any other
        distribution) on shares of Common Stock or any class thereof payable
        from sources other than its retained earnings (as such term is used in
        generally accepted accounting principles); or
 
             (2) the Company shall authorize the granting to the holders of
        shares of Common Stock or any class thereof of rights to subscribe for
        or purchase any shares of capital stock of any class or of any other
        right; or
 
             (3) of any reclassification of shares of Common Stock or any class
        thereof (other than a subdivision or combination of outstanding shares
        of Common Stock or any class thereof), or of any consolidation or merger
        to which the Company is a party and for which approval of any
        stockholders
 
                                        9
<PAGE>   13
 
          of the Company is required, or of the sale or transfer of all or
          substantially all of the assets of the Company; or
 
             (4) of the voluntary or involuntary dissolution, liquidation or
        winding up of the Company;
 
        then the Company shall cause to be filed with the Warrant Agent, and
        shall cause to be mailed to the holders of the Warrants, at their last
        addresses as they shall appear upon the Warrant Register, at least 10
        days prior to the applicable record date hereinafter specified, a notice
        stating (x) the date on which a record is to be taken for the purpose of
        such dividend, distribution or rights, or, if a record is not to be
        taken, the date as of which the holders of Common Stock (or any class
        thereof) of record to be entitled to such dividend, distribution or
        rights are to be determined, or (y) the date on which such
        reclassification, consolidation, merger, sale, transfer, dissolution,
        liquidation or winding up is expected to become effective, and, if
        applicable, the date as of which it is expected that holders of Common
        Stock (or any class thereof) of record shall be entitled to exchange
        their shares of Common Stock for securities or other property (including
        cash) deliverable upon such reclassification, consolidation, merger,
        sale, transfer, dissolution, liquidation or winding up. Failure to give
        any such notice, or any defect therein, shall not affect the validity of
        the proceedings referred to in clauses (1), (2), (3) and (4) above.
 
          (i) Notwithstanding anything to the contrary contained in this Section
     4.01, the Company shall be entitled, but not required, to make such
     reductions in the Warrant Price, in addition to those required by this
     Section 4.01, as it in its discretion shall determine to be advisable,
     including, without limitation, in order that any dividend in or
     distribution of shares of Common Stock (or any class thereof) or shares of
     capital stock of any class other than Common Stock, subdivision,
     reclassification or combination of shares of Common Stock, issuance of
     rights or warrants, or any other transaction having a similar effect, shall
     not be treated as a distribution of property by the Company to its
     stockholders under Section 305 of the Internal Revenue Code of 1986, as
     amended or any successor provision and shall not be taxable to them.
 
          (j) Notwithstanding anything to the contrary contained in this
     Agreement, no adjustment to the Warrant Price or the number of shares of
     Common Stock purchasable upon exercise of a Warrant (or the number of
     Warrants) shall be made as a result of, or in connection with, the issuance
     of (i) options or rights to purchase Common Stock issued to directors,
     officers or employees of the Company or its Subsidiaries pursuant to a
     stock option or other similar plan adopted by the Board of Directors, or
     the modification, renewal or extension of any such plan if approved by the
     Board of Directors, (ii) shares of Common Stock or other securities issued
     by the Company pursuant to and in accordance with the Plan, the Investment
     Agreement or the Related Agreements, or (iii) upon conversion of shares of
     any class of Common Stock into shares of any other class of Common Stock
     pursuant to and in accordance with the provisions of the Certificate of
     Incorporation of the Company as in effect from time to time.
 
     SECTION 4.02.  Adjustment of Shares of Class B Common Stock Purchasable
Upon Exercise of Warrants.  Unless the Company shall have exercised its election
as provided in Section 4.03 hereof, upon each adjustment of the Warrant Price
pursuant to Section 4.01 hereof the number of shares of Class B Common Stock
purchasable upon exercise of a Warrant outstanding prior to the effectiveness of
such adjustment shall be adjusted to the number of shares of Class B Common
Stock, calculated to the nearest one-hundredth of a share, obtained by (i)
multiplying the number of shares of Class B Common Stock purchasable immediately
prior to such adjustment upon the exercise of a Warrant by the Warrant Price in
effect prior to such adjustment, and (ii) dividing the product so obtained by
the Warrant Price in effect after such adjustment of the Warrant Price.
 
     SECTION 4.03.  Election to Adjust Warrants Instead of Shares Per
Warrant.  The Company may elect on or after the date of any adjustment of the
Warrant Price pursuant to Section 4.01 hereof to adjust the number of Warrants
outstanding in substitution for any adjustment in the number of shares of Class
B Common Stock purchasable upon the exercise of a Warrant as provided in Section
4.02 hereof. Each of the Warrants outstanding after such adjustment of the
number of Warrants shall be exercisable for one share of Class B Common Stock.
Each Warrant held of record prior to such adjustment of the number of Warrants
shall become that number of Warrants (calculated to the nearest hundredth)
obtained by (i) multiplying the
 
                                       10
<PAGE>   14
 
number of Warrants held of record prior to adjustment of the number of Warrants
by the Warrant Price in effect prior to adjustment of the Warrant Price, and
(ii) dividing the product so obtained by the Warrant Price in effect after
adjustment of the Warrant Price. The Company shall make a public announcement of
its election to adjust the number of Warrants, indicating the record date for
the adjustment, and, if known at the time, the amount of the adjustment to be
made. This record date may be the date on which the Warrant Price is adjusted or
any day thereafter, but shall not be less than 10 or more than 30 days later
than the date of public announcement. Upon each adjustment of the number of
Warrants pursuant to this Section 4.03, the Company shall cause the Warrant
Agent, as promptly as practicable, to distribute to holders of record of the
Warrant Certificates on such record date either (i) Warrant Certificates
evidencing any additional Warrants to which such holders shall be entitled as a
result of such adjustment, or (ii) in substitution and replacement for the
Warrant Certificates held by such holders prior to the date of adjustment, and
upon surrender thereof, if required by the Company, new Warrant Certificates
evidencing all the Warrants to which such holders shall be entitled after such
adjustment. Warrant Certificates to be so distributed shall be issued, executed
and countersigned in the manner specified in this Agreement (but may bear, at
the option of the Company, the adjusted Warrant Price), shall represent the same
class of Warrants as was represented by the Warrant Certificates so surrendered
and shall be registered in the names of the holders of record of the Warrant
Certificates on the record date specified in the public announcement.
 
     For the purposes of this Section 4.03, "public announcement" shall mean
publication at least once in a newspaper printed in the English language and
customarily published at least once a day for at least five days in each
calendar week and of general circulation in the Borough of Manhattan, New York,
New York.
 
     SECTION 4.04.  No Fractional Warrants to Be Issued.  Notwithstanding
anything to the contrary contained in this Agreement, the Company shall not be
required to issue fractions of Warrants on any distribution of Warrants to
Warrant holders pursuant to Section 4.03 hereof or otherwise or to distribute
Warrant Certificates that evidence fractional Warrants. If any fraction of a
Warrant would, except for the provisions of this Section 4.04, be issuable upon
an adjustment of the Warrant Price and distribution of Warrants pursuant to
Section 4.03 hereof or otherwise, the Company shall, at its option, either (a)
purchase such fraction for an amount in cash equal to the then-current market
value of such fraction computed in accordance with Section 4.01(d) hereof (with
respect to the current market price of the Warrant rather than the per share
current market price of the Class B Common Stock and assuming, for the purpose
of such computation, that the effective date of such adjustment of the Warrant
Price, or such other relevant date, shall be the applicable record date referred
to in Section 4.01(d)) or (b) issue scrip of the Company in lieu thereof,
rounded up to the nearest one-hundredth of a Warrant. Such scrip shall be
exchangeable in combination with other similar scrip for the number of full
Warrants represented thereby, shall be issued in such denominations (not less
than one-hundredth of a Warrant) and in such form, shall expire on the
Expiration Date and may contain such provisions for sale for the account of the
holders of such scrip of the Warrants for which such scrip is exchangeable or
the payment to such holders of the market value of such Warrants, and be subject
to such other terms and provisions, if any, as the Board of Directors may from
time to time determine. The Warrant holders, by their acceptance of the Warrant
Certificates, expressly waive their right to receive any fraction of a Warrant
or a Warrant Certificate representing a fraction of a Warrant upon the
adjustment thereof in accordance with this Article IV or otherwise.
 
     SECTION 4.05.  Rights Upon Consolidation, Merger, Sale, Transfer or
Reclassification.
 
          (a) In case of any consolidation with or merger of the Company into
     another corporation (other than a merger or consolidation in which the
     Company is the continuing corporation), or in case of any lease, sale or
     conveyance to another corporation of the property of the Company as an
     entirety or substantially as an entirety, such successor, leasing or
     purchasing corporation, as the case may be, shall execute with the Warrant
     Agent a supplemental agreement (1) providing that the holder of each
     Warrant then outstanding shall have the right thereafter (until the
     Expiration Date) to receive, upon exercise thereof, in lieu of each share
     of Class B Common Stock deliverable upon such exercise immediately prior to
     such event, only the kind and amount of shares and/or other securities
     and/or property and/or cash receivable upon such consolidation, merger,
     lease, sale or conveyance by a holder of one share of Class B Common Stock,
     and (2) setting forth the Warrant Price for the shares and/or other
 
                                       11
<PAGE>   15
 
     securities and/or property and/or cash so issuable, which shall be an
     amount equal to the Warrant Price per share of Class B Common Stock
     immediately prior to such event.
 
          (b) In case of any liquidation, dissolution or winding up of the
     affairs of the Company, the Company shall make prompt, proportionate,
     equitable, lawful and adequate provision as part of the terms of such
     dissolution, liquidation or winding up such that the holder of a Warrant
     may thereafter receive, on exercise of such Warrant, in lieu of each share
     of Class B Common Stock of the Company which such holder would have been
     entitled to receive upon exercise of such Warrant, the same kind and amount
     of any stock, securities or assets as may be issuable, distributable or
     payable on any such dissolution, liquidation or winding up with respect to
     each share of Class B Common Stock of the Company; provided, however, that
     in the event of any such dissolution, liquidation or winding up, the right
     to exercise the Warrants shall terminate on a date fixed by the Company,
     such date to be not earlier than the 60th day next succeeding the date on
     which notice of such termination of the right to exercise the Warrants has
     been given by mail to the holders thereof in accordance with Section
     4.01(h).
 
          (c) In case of any reclassification or change of the shares of Class B
     Common Stock issuable upon exercise of the Warrants (other than a change in
     par value, or from par value to no par value, or as a result of a
     subdivision or combination) or in case of any consolidation or merger of
     another corporation into the Company in which the Company is the continuing
     corporation and in which the holders of the shares of Common Stock
     thereafter receive shares and/or other securities and/or property and/or
     cash for such shares of Common Stock (including for this purpose shares
     reflecting a change in par value or from par value to no par value or as a
     result of a subdivision or combination of the shares of Common Stock), the
     Company shall execute with the Warrant Agent a supplemental agreement (1)
     providing that the holder of each Warrant then outstanding shall have the
     right thereafter (until the Expiration Date) to receive, upon exercise
     thereof, in lieu of each share of Class B Common Stock, deliverable upon
     such exercise immediately prior to such event, only the kind and amount of
     shares and/or other securities and/or property and/or cash receivable upon
     such reclassification, change, consolidation or merger by a holder of one
     share of Class B Common Stock, and (2) setting forth the Warrant Price for
     the shares and/or other securities and/or property and/or cash so issuable,
     which shall be an amount equal to the Warrant Price per share of Class B
     Common Stock immediately prior to such event. If, as a result of this
     subsection (c), the holder of any Warrant thereafter surrendered for
     exercise shall become entitled to receive shares of two or more classes of
     capital stock of the Company, the Board of Directors (whose determination
     shall be conclusive and shall be described in a statement filed with the
     Warrant Agent) shall determine the allocation of the Warrant Price between
     or among shares of such classes of capital stock.
 
          (d) Any supplemental agreement entered into pursuant to this Section
     4.05 shall, where appropriate, state the Warrant Price in terms of one full
     share of Class B Common Stock of the Company or one full share of the
     common stock of any successor, leasing or purchasing corporation.
 
          (e) The above provisions of this Section 4.05 shall similarly apply to
     successive reclassifications and changes of shares of Class B Common Stock
     and to successive consolidations, mergers, leases, sales or conveyances,
     mutatis mutandis.
 
          (f) Notice of the execution of any such supplemental agreement shall
     be mailed by the Company to registered holders of Warrants as soon as
     practicable after the execution of such supplemental agreement.
 
          (g) In the event that at any time as a result of the provisions of
     this Section 4.05, the holder of any Warrant thereafter surrendered for
     exercise shall become entitled to receive any shares or other securities
     other than shares of Class B Common Stock, thereafter the price or prices
     of such other shares or other securities so receivable upon exercise of any
     Warrant shall be subject to adjustment from time to time in a manner and on
     terms as nearly equivalent as practicable to the provisions of Article IV
     with respect to Class B Common Stock, and the provisions of Article III
     with respect to the Class B Common Stock shall apply on like terms to any
     such other shares or other securities.
 
                                       12
<PAGE>   16
 
     SECTION 4.06.  Covenant to Reserve Shares for Issuance on Exercise.  The
Company covenants that it will at all times reserve and keep available free of
preemptive rights out of its authorized and unissued Class B Common Stock,
solely for the purpose of issue upon exercise of Warrants and exchange of scrip
as herein provided, the full number of shares of Class B Common Stock, if any,
then issuable if all outstanding Warrants then exercisable were to be exercised.
The Company covenants that all shares of Class B Common Stock which shall be so
issuable shall be duly and validly issued and fully paid and non-assessable.
 
     The Company hereby authorizes and directs its current and future transfer
agents for the Class B Common Stock and for any shares of the Company's capital
stock issuable upon the exercise of any of the Warrants at all times to reserve
such number of authorized shares as shall be requisite for such purpose. The
Warrant Agent is hereby authorized to requisition from time to time from any
such transfer agents stock certificates required to honor outstanding Warrants
upon exercise thereof in accordance with the terms of this Agreement, and the
Company hereby authorizes and directs such transfer agents to comply with all
such requests of the Warrant Agent. The Company will supply such transfer agents
with duly executed stock certificates for such purposes and will provide or
otherwise make available any cash or scrip which may be payable as provided in
this Article IV. Promptly after the Expiration Date, the Warrant Agent shall
certify to the Company the aggregate number of Warrants then outstanding, and
thereafter no shares shall be reserved in respect of such Warrants.
 
     SECTION 4.07.  Condition Precedent to Reduction of Warrant Price Below Par
Value of Shares of Class B Common Stock; Compliance with Governmental
Requirements; Suspension of Exercise of Warrants. Before taking any action that
would cause an adjustment reducing the Warrant Price to below the then par value
of any of the shares of Class B Common Stock issuable upon exercise of the
Warrants, the Company will take any corporate action that may, in the opinion of
its counsel, be necessary in order that the Company may validly and legally
issue fully paid and non-assessable shares of such Class B Common Stock at such
adjusted Warrant Price.
 
     The Company covenants that if any shares of Class B Common Stock required
to be reserved for purposes of exercise of Warrants or exchange of scrip
require, under any Federal or state law or rule or regulation of any national
securities exchange, registration with or approval of any governmental
authority, or listing on any national securities exchange before such shares may
be issued upon exercise, the Company will in good faith and as expeditiously as
possible endeavor to cause such shares to be duly registered, approved or listed
on the relevant national securities exchange, as the case may be; provided,
however, that in no event shall such shares of Class B Common Stock be issued,
and the Company is hereby authorized to suspend the exercise of all Warrants,
for the period during which such registration, approval or listing is required
but not in effect.
 
     SECTION 4.08.  Payment of Taxes on Stock Certificates Issued upon
Exercise.  The initial issuance of certificates of Class B Common Stock upon the
exercise of Warrants shall be made without charge to the exercising Warrant
holders for any transfer, stamp or similar tax or for any other governmental
charges that may be imposed in respect of the issuance of such stock
certificates, and such stock certificates shall be issued in the respective
names of, or in such names as may be directed by, the registered holders of the
Warrants exercised; provided, however, that the Company shall not be required to
pay any tax or such other charges that may be payable in respect of any transfer
involved in the issuance and delivery of any such stock certificate, any Warrant
Certificates or other securities in a name other than that of the registered
holder of the Warrant Certificate surrendered upon exercise of the Warrant, and
the Company shall not be required to issue or deliver such certificates or other
securities unless and until the Person or Persons requesting the issuance
thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid.
 
     SECTION 4.09.  Warrant Agent Not Responsible for Adjustments or Validity of
Stock.  The Warrant Agent shall not at any time be under any duty or
responsibility to any Warrant holder to determine whether any facts exist that
may require an adjustment of the Warrant Price, or with respect to the nature or
extent of any such adjustment when made, or with respect to the method employed
herein or in any supplemental agreement in making the same. The Warrant Agent
shall not be accountable with respect to the validity or
 
                                       13
<PAGE>   17
 
value (or the kind or amount) of any shares of Class B Common Stock or of any
securities or property or scrip which may at any time be issued or delivered
upon the exercise of any Warrant or upon any adjustment pursuant to this Article
IV, and it makes no representation with respect thereto. The Warrant Agent shall
not be responsible for any failure of the Company to make any cash payment or to
issue, transfer or deliver any shares of Class B Common Stock or stock
certificates or other securities or property upon the surrender of any Warrant
for the purpose of exercise or upon any adjustment pursuant to this Article IV,
or to comply with any of the covenants of the Company contained in this Article
IV.
 
     SECTION 4.10.  Statements on Warrants.  The form of Warrant Certificate
need not be changed because of any adjustment made pursuant to this Article IV,
and Warrant Certificates issued after such adjustment may state the same Warrant
Price and the same number of shares of Class B Common Stock as are stated in the
Warrant Certificates initially issued pursuant to this Agreement. The Company,
however, may at any time in its sole discretion (which shall be conclusive) make
any change in the form of Warrant Certificate that it may deem appropriate and
that does not affect the substance thereof; and any Warrant Certificate
thereafter issued or countersigned, whether in exchange or substitution for an
outstanding Warrant Certificate or otherwise, may be in the form as so changed.
 
                                   ARTICLE V
 
           OTHER PROVISIONS RELATING TO RIGHTS OF HOLDERS OF WARRANTS
 
     SECTION 5.01.  No Rights as Stockholders.  Nothing contained in this
Agreement or in any Warrant Certificate shall be construed as conferring on the
holder of any Warrant or its transferee any rights whatsoever as a stockholder
of the Company, either at law or equity, including but not limited to the right
to vote at, or to receive notice of, any meeting of stockholders of the Company;
nor shall the consent of any such holder be required with respect to any action
or proceeding of the Company; nor shall any such holder, by reason of the
ownership or possession of a Warrant or the Warrant Certificate representing the
same, either at, before or after exercising such Warrant, have any right to
receive any cash dividends, stock dividends, allotments or rights, or other
distributions (except as specifically provided herein), paid, allotted or
distributed or distributable to the stockholders of the Company prior to the
date of the exercise of such Warrant, nor shall such holder have any right not
expressly conferred by this Agreement or the Warrant Certificate that he holds.
 
     SECTION 5.02.  Mutilated or Missing Warrant Certificates.  If any Warrant
Certificate is lost, stolen, mutilated or destroyed, the Company shall issue and
the Warrant Agent shall countersign, in exchange and substitution for and upon
cancellation of the mutilated Warrant Certificate, or in lieu of and
substitution for the Warrant Certificate lost, stolen or destroyed, upon receipt
of a proper affidavit or other evidence satisfactory to the Company and the
Warrant Agent (and surrender of any mutilated Warrant Certificate) and bond of
indemnity in form and amount and with corporate surety satisfactory to the
Company and the Warrant Agent in each instance protecting the Company and the
Warrant Agent, a new Warrant Certificate of like tenor and representing an
equivalent number of Warrants as the Warrant Certificate so lost, stolen,
mutilated or destroyed. Any such new Warrant Certificate shall constitute an
original contractual obligation of the Company, whether or not the allegedly
lost, stolen, mutilated or destroyed Warrant Certificate shall be at any time
enforceable by anyone. An applicant for such a substitute Warrant Certificate
shall also comply with such other reasonable regulations and pay such other
reasonable charges as the Company or the Warrant Agent may prescribe.
Notwithstanding the foregoing, in the event that a lost, stolen, mutilated or
destroyed Warrant Certificate was held by a Person to which Warrant Certificates
were originally issued pursuant to Section 2.03(a), [(b)] or (c), or by a Person
holding Warrants to purchase not less than 100,000 shares of Class B Common
Stock, (i) an indemnity agreement from such Person in lieu of a bond shall be
acceptable and (ii) no charges shall be made for such substitution. All Warrant
Certificates shall be held and owned upon the express condition that the
foregoing provisions are exclusive, with respect to the replacement of lost,
stolen, mutilated or destroyed Warrant Certificates, and shall preclude any and
all other rights or remedies notwithstanding any law or statute existing or
hereafter enacted to the contrary with respect to the replacement of negotiable
instruments or other securities without their surrender.

<PAGE>   18
 
     SECTION 5.03.  Delivery of Prospectuses.  If, and to the extent that, the
Company may be required by the 1933 Act or any other applicable Federal or state
law to furnish a prospectus to Warrant holders upon their exercise of Warrants,
the Company shall cause to be kept, either at the Warrant Agent's Office or at
such other location designated by the Company, sufficient quantities of such
prospectuses for delivery to Warrant holders upon their exercise of Warrants,
and shall deliver such prospectuses or cause such prospectuses to be delivered
to such Warrant holders together with the shares of Class B Common Stock or
other securities receivable by such Warrant holders upon their exercise of
Warrants.
 
                                   ARTICLE VI
 
                          CONCERNING THE WARRANT AGENT
 
     SECTION 6.01.  Payment of Certain Taxes.  The Company will from time to
time promptly pay all transfer, stamp or similar taxes and all other
governmental charges that may be imposed upon the Company or otherwise in
respect of the initial issuance or delivery of shares of Class B Common Stock
upon the exercise of Warrants, but the Company shall not be obligated to pay any
transfer, stamp or similar taxes or other governmental charges in respect of any
transfer of the Warrants or such shares effected by any holder thereof.
 
     SECTION 6.02.  Change of Warrant Agent.
 
          (a) The Warrant Agent, or any successor to it hereafter appointed, may
     resign its duties and be discharged from all further duties and liabilities
     hereunder (except liabilities arising as a result of the Warrant Agent's
     own negligence, willful misconduct or bad faith) after giving 60 days'
     notice in writing to the Company, except that such shorter notice may be
     given as the Company and AmWest shall, in writing, accept as sufficient. At
     least 15 days prior to the date such resignation is to become effective,
     the Warrant Agent shall cause a copy of such notice of resignation to be
     mailed to the registered holder of each Warrant Certificate. If the office
     of the Warrant Agent becomes vacant by resignation or incapacity to act or
     otherwise, the Company shall appoint a successor Warrant Agent in place of
     the Warrant Agent [; provided that in the event that AmWest is the holder
     of any Warrants at such time, the Company shall notify and consult with
     AmWest with respect to such proposed appointment]. If the Company shall
     fail to make such appointment within a period of 60 days after it has been
     notified in writing of such resignation or incapacity by the resigning or
     incapacitated Warrant Agent or by any holder of Warrants (who shall, with
     such notice, submit a copy of his Warrant Certificate for inspection by the
     Company), then the holder of any Warrants may apply, at the expense of the
     Company, to any court of competent jurisdiction for the appointment of a
     successor warrant agent.
 
          (b) The Warrant Agent may be removed by the Company at any time upon
     30 days' written notice to the Warrant Agent; provided, that the Warrant
     Agent shall not be removed until a successor Warrant Agent meeting the
     qualifications hereof shall have been appointed and provided further that
     in the event AmWest is the holder of any Warrants at such time, the Company
     shall obtain the consent of AmWest, which consent shall not be unreasonably
     withheld.
 
          (c) Any successor Warrant Agent, whether appointed by the Company or
     by a court, shall be a corporation organized, in good standing and doing
     business under the laws of the United States of America or any state
     thereof or the District of Columbia, and authorized under such laws to
     exercise corporate trust powers and subject to supervision or examination
     by Federal or state authority and having a combined capital and surplus of
     not less than $10,000,000. The combined capital and surplus of any such
     successor Warrant Agent shall be deemed to be the combined capital and
     surplus as set forth in the most recent report of its condition published
     prior to its appointment pursuant to law or to the requirements of a
     Federal or state supervising or examining authority. After appointment, any
     successor Warrant Agent shall be vested with all the authority, powers,
     rights, immunities, duties and obligations of its predecessor Warrant Agent
     with like effect as if originally named as Warrant Agent hereunder, without
     any further assurance, conveyance, act or deed; provided, however, that in
     no event shall any successor Warrant Agent be liable for any breach,
     default or failure of performance by the predecessor Warrant Agent of any
     covenant or obligation under this Agreement existing on the date the
     successor
 
                                       15
<PAGE>   19
 
     Warrant Agent assumes authority pursuant to this Section 6.02. If for any
     reason it becomes necessary or appropriate, the predecessor Warrant Agent
     shall execute and deliver, at the expense of the Company, an instrument
     transferring to such successor Warrant Agent all the authority, powers and
     rights of such predecessor Warrant Agent hereunder; and upon request of any
     successor Warrant Agent, the Company shall make, execute, acknowledge and
     deliver any and all instruments in writing to more fully and effectually
     vest in and confirm to such successor Warrant Agent all such authority,
     powers, rights, immunities, duties and obligations. Upon assumption by a
     successor Warrant Agent of the duties and responsibilities hereunder, the
     predecessor Warrant Agent shall deliver and transfer, at the expense of the
     Company, to the successor Warrant Agent any property at the time held by it
     hereunder. As soon as practicable after such appointment, the Company shall
     give notice thereof to the predecessor Warrant Agent, the registered
     holders of the Warrants and each transfer agent for the shares of its Class
     B Common Stock. Failure to give such notice, or any defect therein, shall
     not affect the validity of the appointment of the successor Warrant Agent.
 
          (d) Any corporation into which the Warrant Agent may be merged or with
     which it may be consolidated, or any corporation resulting from any merger
     or consolidation to which the Warrant Agent shall be a party, shall be the
     successor Warrant Agent under this Agreement without any further act,
     provided that such corporation is eligible for appointment as a successor
     to the Warrant Agent. Any such successor Warrant Agent shall promptly cause
     notice of its succession as Warrant Agent to be mailed to the Company and
     to the registered holder of each Warrant Certificate. In case at the time
     such successor Warrant Agent shall succeed to the agency created by this
     Agreement, any of the Warrant Certificates shall have been countersigned
     but not delivered, any such successor Warrant Agent may adopt the
     countersignature of the original Warrant Agent and deliver such Warrant
     Certificates so countersigned, and in case at that time any of the Warrant
     Certificates shall not have been countersigned, any successor to the
     Warrant Agent may countersign such Warrant Certificates either in the name
     of the predecessor Warrant Agent or in the name of the successor Warrant
     Agent; and in all such cases Warrant Certificates shall have the full force
     provided in the Warrant Certificates and in this Agreement.
 
          (e) In case at any time the name of the Warrant Agent shall be changed
     and at such time any of the Warrant Certificates shall have been
     countersigned but not delivered, the Warrant Agent may adopt the
     countersignatures under its prior name and deliver such Warrant
     Certificates so countersigned; and in case at that time any of the Warrant
     Certificates shall not have been countersigned, the Warrant Agent may
     countersign such Warrant Certificates either in its prior name or in its
     changed name; and in all such cases such Warrant Certificates shall have
     the full force provided in the Warrant Certificates and in this Agreement.
 
     SECTION 6.03.  Compensation; Further Assurances.  The Company agrees (i)
that it will pay the Warrant Agent the fees set forth in Exhibit B for its
services as Warrant Agent hereunder and, except as otherwise expressly provided,
will pay or reimburse the Warrant Agent upon demand for all reasonable expenses,
disbursements and advances incurred or made by the Warrant Agent in accordance
with any of the provisions of this Agreement (including the reasonable
compensation, expenses and disbursements of its agents and counsel) except any
such expense, disbursement or advance as may arise from its or any of their
negligence, willful misconduct or bad faith; and (ii) that it will perform,
execute, acknowledge and deliver or cause to be performed, executed,
acknowledged and delivered all such further and other acts, instruments and
assurances as may reasonably be required by the Warrant Agent for the carrying
out or performing of the provisions of this Agreement.
 
     SECTION 6.04.  Reliance on Counsel.  The Warrant Agent may consult with
legal counsel (who may be legal counsel for the Company), and the written
opinion of such counsel or any advice of legal counsel subsequently confirmed by
a written opinion of such counsel shall be full and complete authorization and
protection to the Warrant Agent as to any action taken or omitted by it in good
faith and in accordance with such written opinion or advice, provided that such
counsel shall be reasonably acceptable to the Company.
 
     SECTION 6.05.  Proof of Actions Taken.  Whenever in the performance of its
duties under this Agreement the Warrant Agent shall deem it necessary or
desirable that any matter be proved or established by
 
                                       16
<PAGE>   20
 
the Company prior to taking or suffering or omitting any action hereunder, such
matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of bad faith on the part of the Warrant Agent,
be deemed to be conclusively proved and established by an Officers' Certificate
delivered to the Warrant Agent; and such Officers' Certificate shall, in the
absence of bad faith on the part of the Warrant Agent be full authority to the
Warrant Agent for any action taken, suffered or omitted in good faith by it
under the provisions of this Agreement in reliance upon such certificate; but in
its discretion the Warrant Agent may in lieu thereof accept other evidence of
such fact or matter or may require such further or additional evidence as to it
may deem reasonable.
 
     SECTION 6.06.  Correctness of Statements.  The Warrant Agent shall not be
liable for or by reason of any of the statements of fact or recitals contained
in this Agreement or in the Warrant Certificates (except its countersignature
thereof) or be required to verify the same, and all such statements and recitals
are and shall be deemed to have been made by the Company only.
 
     SECTION 6.07.  Validity of Agreement.  The Warrant Agent shall not be under
any responsibility in respect of the validity of this Agreement or the execution
and delivery hereof (other than such execution and delivery by the Warrant
Agent) or in respect of the validity or execution of any Warrant Certificates
(except its countersignature thereof); nor shall it be responsible for any
breach by the Company of any covenant or condition contained in this Agreement
or in any Warrant Certificate; nor shall it by any act hereunder be deemed to
make any representation or warranty as to the authorization or reservation of
any shares of Class B Common Stock to be issued pursuant to this Agreement or
any Warrants or as to whether any shares of Class B Common Stock will, when
issued, be validly issued and fully paid and non-assessable.
 
     SECTION 6.08.  Use of Agents.  The Warrant Agent may execute and exercise
any of the rights or powers hereby vested in it or perform any duty hereunder
either itself or by or through its attorneys or agents and the Warrant Agent
shall not be responsible for the misconduct or negligence of any agent or
attorney, provided due care had been exercised in the appointment and continued
employment thereof.
 
     SECTION 6.09.  Liability of Warrant Agent.  The Warrant Agent shall incur
no liability or responsibility to the Company or to any holder of Warrants for
any action taken in reliance on any notice, resolution, waiver, consent, order,
certificate, or other paper, document or instrument believed by it to be genuine
and to have been signed, sent or presented by the proper party or parties. The
Company agrees to indemnify the Warrant Agent and hold it harmless against any
and all liabilities, including judgments, costs and reasonable counsel fees, for
anything done or omitted in good faith by the Warrant Agent in the execution of
this Warrant Agreement, except as a result of the Warrant Agent's negligence or
willful misconduct or bad faith.
 
     SECTION 6.10.  Legal Proceedings.  The Warrant Agent shall be under no
obligation to institute any action, suit or legal proceeding or to take any
other action likely to involve expense unless the Company or one or more holders
of Warrants shall furnish the Warrant Agent with reasonable security and
indemnity for any costs and expenses which may be incurred, but this provision
shall not affect the power of the Warrant Agent to take such action as the
Warrant Agent may consider proper, whether with or without any such security or
indemnity.
 
     SECTION 6.11.  Other Transactions in Securities of the Company.  The
Warrant Agent in its individual or any other capacity may become the owner of
the Warrants or other securities of the Company, or become pecuniarily
interested in any transaction in which the Company may be interested, or
contract with or lend money to the Company or otherwise act as fully and freely
as though it were not Warrant Agent under this Warrant Agreement. Nothing herein
shall preclude the Warrant Agent from acting in any other capacity for the
Company or for any other legal entity.
 
     SECTION 6.12.  Actions as Agent.  The Warrant Agent shall act hereunder
solely as agent and not in a ministerial capacity, and its duties shall be
determined solely by the provisions hereof. The Warrant Agent shall not be
liable for anything which it may do or refrain from doing in good faith in
connection with this Agreement except for its own negligence or willful
misconduct or bad faith.
 
     SECTION 6.13.  Appointment and Acceptance of Agency.  The Company hereby
appoints the Warrant Agent to act as agent for the Company in accordance with
the instructions set forth in this Agreement, and the
 
                                       17
<PAGE>   21
 
Warrant Agent hereby accepts the agency established by this Agreement and agrees
to perform the same upon the terms and conditions herein set forth.

                            MISCELLANEOUS PROVISIONS
 
     SECTION 7.01.  Supplements and Amendments.

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

<PAGE>   25
 
Agreement, which terms and provisions are hereby incorporated by reference
herein and made a part hereof. Every holder of this Warrant Certificate consents
to all of the terms contained in the Warrant Agreement by acceptance hereof. A
copy of the Warrant Agreement is available for inspection by the registered
holder hereof at the Warrant Agent's Office.
 
     The Company shall not be required upon the exercise of the Warrants
represented hereby to issue fractions of shares of Class B Common Stock, to
distribute stock certificates that evidence fractional shares of Class B Common
Stock or to issue Warrant Certificates representing fractional Warrants, but
shall make adjustment in cash or scrip for any fraction of a share which the
same registered holder of Warrants exercised in the same transaction would have
been entitled to purchase on the basis of the then-current market value of any
such fraction of a share (computed as provided in the Warrant Agreement). If the
Warrants represented hereby shall be exercised in part, the registered holder
hereof shall be entitled to receive, upon surrender hereof, another Warrant
Certificate for the balance of the number of whole Warrants not exercised as
provided in the Warrant Agreement.
 
     Commencing on the day after the Distribution Date, this Warrant Certificate
may be exchanged either separately or in combination with other Warrant
Certificates at the Warrant Agent's Office for new Warrant Certificates
representing the same aggregate number of Warrants evidenced by the Warrant
Certificate or Warrant Certificates exchanged, upon surrender of this Warrant
Certificate and upon compliance with and subject to the conditions set forth
herein and in the Warrant Agreement.
 
     Commencing on the day after the Distribution Date, this Warrant Certificate
is transferable at the Warrant Agent's Office by the registered holder hereof in
Person or by his attorney duly authorized in writing, upon surrender of this
Warrant Certificate and upon compliance with and subject to the conditions set
forth herein and in the Warrant Agreement. Upon any such transfer, a new Warrant
Certificate or new Warrant Certificates of different denominations, representing
in the aggregate a like number of Warrants, will be issued to the transferee.
Every holder of Warrants, by accepting this Warrant Certificate, consents and
agrees with the Company, the Warrant Agent and with every subsequent holder of
this Warrant Certificate that until due presentation for the registration of
transfer of this Warrant Certificate on the Warrant Register maintained by the
Warrant Agent, the Company and the Warrant Agent may deem and treat the Person
in whose name this Warrant Certificate is registered as the absolute and lawful
owner for all purposes whatsoever and neither the Company nor the Warrant Agent
shall be affected by any notice to the contrary.
 
     The Company is authorized by the Warrant Agreement to suspend the exercise
of all Warrants for any period during which any shares of Class B Common Stock
reserved for exercise of Warrants require, under any Federal or state law or
rule or regulation of any national securities exchange, registration with or
approval of any governmental authority or listing on any national securities
exchange and such registration, approval or listing is not in effect.
 
     Nothing contained in the Warrant Agreement or in this Warrant Certificate
shall be construed as conferring on the holder of any Warrants or his transferee
any rights whatsoever as a stockholder of the Company.
 
     This Warrant Certificate shall not be valid unless countersigned manually
by the Warrant Agent.
 
     The Warrant Agreement and each Warrant Certificate, including this Warrant
Certificate, shall be deemed a contract made under the laws of the State of New
York and for all purposes shall be governed by and construed in accordance with
the laws of the State of New York.

     agree to recommend to the Independent Directors to vote or provide written
     consents in favor of such designees and to take any other action necessary
     to elect such designees.
 
          (b) Three (3) Creditors' Committee Directors, one (1) Equity Committee

     than five (5) days in advance of any meeting of the Board at which a

     forth above and provided that the Stockholder Representatives shall select
     any Successor Independent Director to replace the Independent Company
     Director from among the executive officers of the Company. Each of AmWest
     and GPA agrees to vote the Common Stock held and controlled by them and to
     cause the AmWest Directors and the GPA Director, respectively, to vote or
     provide written consents in favor of such designees and to take any other

     Director shall be reasonably acceptable to AmWest at the time of his or her
     initial designation.

     the first Annual Meeting following the Effective Date and until the

     thirty (30) days in advance of each Annual Meeting prior to (but not
     including) the Third Annual Meeting, and no less than five (5) days in
     advance of any other meeting of the Board at which a director will be

     of death, disability, removal, resignation or otherwise, GPA shall give
     written notice to the other parties hereto designating the individual to
     serve as GPA Director. Unless the rights of GPA hereunder have been

     Stockholder Representatives agree to recommend to the Independent
     Directors, to vote or provide written consents in favor of such designee
     and to take any other action necessary to elect such designee; provided
     that the GPA Director shall be reasonably acceptable to AmWest at the time
     of his or her initial designation.
 
          (d) Except as otherwise provided herein, each of AmWest, the
     Stockholder Representatives, and GPA agrees to nominate or cause the
     nomination of the AmWest Directors, the Independent Directors, and the GPA
     Director, respectively, in accordance with the Bylaws.

     to vote any shares for which the voting rights have been suspended, whether
     voluntarily or involuntarily.
 
          (f) In the event that AmWest, the Creditors' Committee or Equity
     Committee (for so long as each is in existence and has the ability to
     designate a director as herein provided), the Stockholder Representatives,
     or GPA shall fail or refuse to designate a nominee to the Board for a
     position allocated to and to be filled by such group or entity as herein
     provided, such position shall not be filled and shall remain vacant unless
     and until such designation shall be made as herein provided.
 
          (g) In the event that the rights and obligations of GPA with respect
     to this Agreement are terminated in accordance with Section 6.2, GPA agrees
     to cause the resignation of, or provide notice to the other parties hereto
     as provided in subsection (h)(i) below requesting removal of the GPA
     Director, at which time the Board shall be reduced to fourteen (14)
     persons.
 
          (h) The parties hereto agree (i) to vote the Common Stock held and
     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 the exclusive right to remove or replace
     such director by written notice as herein provided; except that nothing in
     this agreement shall be construed to limit or prohibit the removal of any
     director for cause.
 
     2.2 Until the Third Annual Meeting, at least eight of the AmWest Directors,
at least two of the Creditors' Committee Directors, the Equity Committee
Director, and the Independent Company Director shall each be Citizens of the
United States.

5. RIGHTS UPON BREACH.
 
     5.1 Each party hereto recognizes and agrees that a violation of any term,
provision, or condition of this Agreement may cause irreparable damage to the
other parties which is difficult or impossible to quantify or ascertain and that
the award of any sum of damages may not be adequate relief to such other
parties. Each party hereto therefore agrees that in the event of any breach of
this Agreement, the other party or parties shall, in addition to any remedies at
law which may be available, have the right to obtain appropriate equitable
(including, but not limited to, injunctive) relief. All remedies hereunder shall
be cumulative and not exclusive.
 
     5.2 In addition to any other remedies available at law or in equity, each
party hereto agrees that the Company shall have the right (a) to withhold
transfer, and to instruct any transfer agent for securities of the Company to
withhold transfer, of any certificates evidencing shares of Common Stock held by
AmWest or any partner or Affiliate of AmWest or transferee if the Company
reasonably believes that such transfer would not be in material compliance with
the terms and provisions of this Agreement, unless the transferee provides to
the Company an opinion of legal counsel reasonably acceptable to the Company
that such transfer will be in material compliance with the terms and provisions
hereof, and (b) to require any person requesting such transfer to provide such
information as may reasonably be requested by the Company regarding ownership of
securities, affiliations, if any, between AmWest and the transferee and such
other matters pertaining to the transfer as may be appropriate to enable the
Company to determine the compliance of the proposed transfer of securities with
the terms and provisions of this Agreement.
 
6. TERMINATION.
 
     6.1 This Agreement shall automatically terminate without any action by any
party on the day immediately preceding the Third Annual Meeting and shall not be
extended except in accordance with Section 7.3. Upon such termination, the
rights and obligations of each party hereunder shall terminate and the
provisions of this Agreement shall be of no force and effect; provided that no
such termination shall relieve any person or entity from liability for breach or
default of this Agreement prior to such termination.

obligations under Section 2.1(g)) shall terminate immediately and without notice

sale or transfer by GPA of equity securities of the Company resulting in the
holding by GPA of less than two percent (2%) of the voting equity securities of
the Company (on a fully diluted basis), or (c) any occurrence, other than as
described in clause (b) above, resulting in the holding by GPA of less than two
percent (2%) of the voting equity securities of the Company (on a fully diluted
basis) if (i) the Company files a Form 10-Q under the Exchange Act, or other
written report or statement, that is delivered to
 
                                        7
<PAGE>   8
 
GPA and a copy to the party designated in Section 7.1, reflecting information as
to the Company's total issued and outstanding capital stock as of a date therein
specified (the "Determination Date") from which GPA can determine whether it
holds less than two percent (2%) of the voting equity securities of the Company
(on a fully diluted basis) and (ii) GPA fails to acquire (by purchase, or
otherwise) sufficient voting equity securities of the Company such that it
continues to hold less than two percent (2%) of the voting equity securities of
the Company (on a fully diluted basis) determined as of the Determination Date
for thirty-five (35) days after delivery of such Form 10-Q, or provision of such
report or statement to GPA. GPA acknowledges that the Company's continuing with
its existing procedures for the distribution of Form-10Qs constitutes delivery
to GPA within the meaning of this Section 6.2.

        Company with a Notice of Demand[; and
 
             (ii) if at any time during the Shelf Period the Shelf Registration
        Statement is not effective for any reason (other than under the
        circumstances and during the periods permitted by the proviso to Section
        2.1(b)), each of Investor and Fidelity may, at any time and from time to
        time, provide the Company with up to two (2) additional Notices of
        Demand.]
 
     Upon receipt of a Notice of Demand, the Company shall use [commercially
     reasonable] [its best] 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 Section 2.2(c)), 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), effected [(A) one (1) registration of Registrable
     Securities with respect to
 
                                        4
<PAGE>   8
 
     a registration requested pursuant to Section 2.2(a)(i) and (B) four (4)
     registrations of Registrable Securities with respect to a registration
     requested pursuant to Section 2.2(a)(ii); (ii) during any period (occurring
     no more than twice during any twelve (12) month period and not to exceed
     forty-five (45) days) in which such registration would require the Company
     to disclose a material 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; or (iii) during any period
     (not to exceed forty-five (45) days) if each of the Company, Investor and
     each Fidelity Fund agrees in writing to suspend such registration for such
     period.
 
          (c) Notice to certain non-Requesting Holders.  Upon receipt of any
     Notice of Demand from a Requesting Holder, the Company will give prompt
     (but in any event within           (     ) days after such receipt) notice
     to all Holders of Registrable Securities of such Notice of Demand and of
     such Holders' rights under this Section 2.2. Upon the request of any such
     Holder made within           (     ) 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] [its best] efforts to effect the registration of all
     Registrable Securities which the Company has been so requested to register
     pursuant to the Notice of Demand.
 
          (d) Priority in Demand Registrations.  If (i) a registration pursuant
     to this Section 2.2(c) 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 the amount of securities requested to
     be included in such registration exceeds the amount which can be sold in
     (or during the time of) such offering within a price range acceptable to
     the Requesting Holder, then the Company will include in such registration
     such amount of securities which the Company is so advised can be sold in
     (or during the time of) such offering as follows: first, such Registrable
     Securities requested to be included in such registration by the Requesting
     Holder, its Affiliates and any direct or indirect transferees of its
     Registrable Securities 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 second, 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.
 
        2.3 Piggyback Registration.
 
          (a) Right to Include Registrable Securities.  If the Company at any
     time proposes to register any of its equity securities under the Securities
     Act (other than by a registration on Form S-4 or Form S-8 or any successor
     or similar form then in effect and other than pursuant to Section 2.1 or
     2.2) in a form and in a manner that would permit registration of the
     Registrable Equity Securities, whether or not for sale for its own account,
     it will give prompt (but in no event less than [thirty (30)] days prior to
     the proposed date of filing the registration statement relating to such
     registration) notice to all Holders of Registrable Equity Securities of the
     Company's intention to do so and of such Holders' rights under this Section
     2.3. Upon the request of any such Holder made within [twenty (20)] days
     after the receipt by such Holder of any such notice (which request shall
     specify the Registrable Equity Securities intended to be disposed of by
     such Holder and the intended method or methods of disposition thereof) (the
     "Piggyback Registration Notice"), the Company will use [commercially
     reasonable] [its best] efforts to effect the registration under the
     Securities Act of all Registrable Equity Securities which the Company has
     been so requested to register by the Holders thereof, to the extent
     required to permit the disposition (in accordance with the intended method
     or methods thereof as aforesaid) of the Registrable Equity Securities so to
     be registered, provided that if, at any time after giving notice of its
     intention to register any equity securities and prior to the effective date
     of the registration statement filed in connection with such registration,
     the Company shall determine for any reason not to register or to delay
     registration of such equity securities, the Company may, at its election,
     give notice of such determination to each such Holder and, thereupon, (i)
     in the case of a determination not to register, shall be relieved of its
     obligation to register any
 
                                        5
<PAGE>   9
 
     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 or
     shall relieve the Company of its obligation to effect any registration
     under such Sections.
 
          (b) Priority in Piggyback Registrations.  If (i) a registration
     pursuant to this Section 2.3 involves an underwritten offering of the
     securities being registered, whether or not for sale for the account of the
     Company, to be distributed (on a firm commitment basis) by or through one
     or more underwriters of recognized standing under underwriting terms
     appropriate for such a transaction and (ii) the managing underwriter of
     such underwritten offering shall inform the Company and the Holders
     requesting such registration by letter of its belief that the amount of
     securities requested to be included in such registration exceeds the amount
     which can be sold in (or during the time of) such offering within a price
     range acceptable to the Company, then the Company will include in such
     registration such amount of securities which the Company is so advised can
     be sold in (or during the time of) such offering as follows: first, all
     securities proposed by the Company to be sold for its own account; second,
     such Registrable Equity Securities requested to be included in such
     registration by Investor, any Fidelity Fund or any of their respective
     Affiliates pro rata on the basis of the amount of such securities so
     proposed to be sold and so requested to be included by such parties; third,
     such Registrable Equity Securities requested to be included in such
     registration by all other Holders pro rata on the basis of the amount of
     such securities so proposed to be sold and so requested to be included by
     such Holders; and fourth, 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 Trust Indenture Act Qualification; Rating.  At or prior to the
     date the SEC declares the Shelf Registration Statement to be effective, the
     Company shall qualify the Indenture under the Trust Indenture Act, and
     shall use [commercially reasonable] [its best] 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
     remains effective for [nine (9)] months]; provided, however, that if (i)
     after such registration statement has been declared effective, the offering
     of Registrable Securities pursuant to such registration statement is
     interfered with by 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 in connection
     with such registration have not been satisfied (for reasons other than a
     wrongful or bad faith act, omission or misrepresentation by the
 
                                        6
<PAGE>   10
 
     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] [its
     best] 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
     the reasonable fees and expenses paid by the Company hereunder to the
     extent such fees and expenses would customarily have been paid by sellers
     in connection with a registration of similar securities or (ii) the
     Requesting Holder elects to terminate such registration due to the
     occurrence of a Material Adverse Change; provided, however, that only one
     such withdrawal shall be permitted pursuant to this clause (ii).
 
          (g) Registration Procedures.  In connection with the Company's
     obligations to register Registrable Securities pursuant to this Agreement,
     the Company will use [commercially reasonable] [its best] 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 possible) file with the SEC
        the requisite registration statement containing all information required
        thereby to effect such registration and thereafter use [commercially
        reasonable] [its best] 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 ten (10) days prior to such filing), the Company
        will furnish to the Participating Holders or their counsel copies of
        reasonably complete drafts of all such documents proposed to be filed
        (excluding exhibits, which shall be made available upon request by any
        Participating Holder), and any such Holder shall have the opportunity to
        object to any information contained therein and the Company will make
        the corrections reasonably requested by such Holder with respect to such
        information prior to filing any such registration statement, amendment,
        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 [nine (9) months] in the case of a registration effected
        pursuant to Section 2.2 or 2.3 (or such shorter period as shall be
        necessary to complete the distribution of the securities covered
        thereby, but not before the expiration of the applicable period referred
        to in Section 4(3) of the Securities Act and Rule 174 thereunder), and
        comply with the provisions of the
 
                                        7

          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 such amendment and supplement thereto
        (in each case including all exhibits and documents incorporated by
        reference), such number of copies of the prospectus contained in such
        registration statement (including each preliminary prospectus and any
        summary prospectus) and any other prospectus filed under Rule 424 under
        the Securities Act relating to such Holder's Registrable Securities, in
        conformity with the requirements of the Securities Act, and such other
        documents as such Holder, underwriter or agent may reasonably request to
        facilitate the disposition of such Registrable Securities;
 
             (iv) use [commercially reasonable] [its best] efforts to register
        or qualify all Registrable Securities and other securities covered by
        such registration statement under (A) with respect to the Shelf
        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] [its best] efforts to cause all
        Registrable Securities covered by such registration statement to be
        registered with or approved by such other governmental agencies or
        authorities applicable to the Company as may be reasonably necessary to
        enable the seller or sellers thereof (or underwriter or agent, if any)
        to consummate the disposition of such Registrable Securities in
        accordance with the plan of distribution set forth in such registration
        statement;
 
             (vi) furnish to each Holder of at least   percent (   %) in

           includes an underwritten public offering, dated the date of the
           closing under the underwriting agreement), and
 
                (B) a "comfort" letter, dated the effective date of such
           registration statement (and, if such registration includes an

           underwriting agreement), signed by the independent public accountants
           who have certified the Company's financial statements included in
           such registration statement,
 
        in each case, reasonably satisfactory in form and substance to such
        Holder (and underwriter or agent and their respective counsel) and
        covering substantially the same matters with respect to such
        registration statement (and the prospectus included therein) and, in the
        case of the accountants' letter, with respect to events subsequent to
        the date of such financial statements, as are customarily covered in
        opinions of issuer's counsel and in accountants' letters delivered to
        the underwriter or agent in underwritten public offerings of securities;
 
             (vii) promptly notify each Holder and any underwriter or agent
        participating in the disposition of Registrable Securities covered by
        such registration statement, at any time when a prospectus relating
        thereto is required to be delivered under the Securities Act, upon
        discovery that, or upon the
 
                                        8
<PAGE>   12
 
          happening of any event known to the Company as a result of which, the
          prospectus included in such registration statement, as then in effect,
          includes an untrue statement of a material fact or omits to state any
          material fact required to be stated therein or necessary to make the
          statements therein not misleading in light of the circumstances under
          which they were made, and promptly prepare and furnish to such Holder
          (or underwriter or agent, if any) a reasonable number of copies of a
          supplement to or an amendment of such prospectus as may be necessary
          so that, as thereafter delivered to the purchasers of such securities,
          such prospectus shall not include an untrue statement of a material
          fact or omit to state a material fact required to be stated therein or
          necessary to make the statements therein not misleading in light of
          the circumstances under which they were made;
 
             (viii) otherwise use [commercially reasonable] [its best] efforts
        to comply with all applicable rules and regulations of the SEC, and make
        available to its security holders, as soon as reasonably practicable

        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;

        any filings required to be made with the National Association of
        Securities Dealers;
 
             (xii) use [commercially reasonable] [its best] efforts to prevent
        the issuance by the SEC or any other governmental agency or court of a
        stop order, injunction or other order suspending the effectiveness of
        such registration statement and, if such an order is issued, use
        [commercially reasonable] [its best] efforts to cause such order to be
        lifted as promptly as practicable;
 
             [(xiii) enter into such agreements and take such other actions as
        the Requisite Holders of such Registrable Securities shall reasonably

                (D) of the receipt by the Company of any notification with
           respect to the suspension of the qualification of any Registrable
           Securities for sale under the applicable securities or blue sky laws
           of any jurisdiction;
 
             (xv) cooperate with each seller of Registrable Securities and each
        underwriter or agent participating in the distribution of such
        Registrable Securities to facilitate the timely preparation and delivery
        of certificates (which shall not bear any restrictive legends, other
        than as required by applicable law, the Investment Agreement or the Note
        Purchase Agreement) representing securities sold under a registration
        statement hereunder, and enable such securities to be in such
        denominations and registered in such names as such seller, underwriter
        or agent may request and keep available and make available to the
        Company's transfer agent, prior to the effectiveness of such
        registration statement, an adequate supply of such certificates;
 
             (xvi) not later than the effective date of such registration
        statement, provide a CUSIP number for all Registrable Securities covered
        by a registration statement hereunder;
 
             (xvii) incorporate in the registration statement or any amendment,
        supplement or post-effective amendment thereto such information as each
        Holder, the underwriter or agent (if any) or their respective counsel
        may reasonably request to be included therein with respect to any
        Registrable Securities being sold by such Holder to such underwriter or
        agent, the purchase price being paid therefor by such underwriter or
        agent and any other terms of the offering of such Registrable
        Securities;
 
             (xviii) during any period when a prospectus is required to be
        delivered under the Securities Act, make periodic filings with the SEC
        pursuant to and containing the information required by the Exchange Act
        (whether or not the Company is required to make such filings pursuant to
        such Act);
 
             (xix) in connection with an underwritten offering, participate, to
        the extent reasonably requested by the Requisite Holders or the managing
        underwriter for the offering, in customary efforts to sell the
        securities under the offering, including, without limitation,
        participating in "road shows."
 
          (h) Agreements of Certain Holders.  (i) Each Holder of Registrable
     Securities as to which any registration is being effected shall furnish to
     the Company such information regarding such Holder, the Registrable
     Securities held by such Holder and the intended plan of distribution of
     such securities as the Company may from time to time reasonably request in
     writing in connection with such registration. If any registration statement
     refers to Investor, any Fidelity Fund or any of their respective Affiliates
     by name or otherwise as the holder of any securities of the Company, then
     such Holder shall have the right to require [(A) the insertion therein of
     language, in form and substance reasonably satisfactory to such Holder, to
     the effect that the holding by such Holder of such securities is not to be
     construed as a recommendation by such Holder of the investment quality of
     the Company's securities covered thereby and that such holding does not
     imply that such Holder will assist in meeting any future financial
     requirements of the Company, or (B)] in the event that such reference to
     such Holder by name or otherwise is not required by the Securities Act or
     any similar federal or state blue sky statute and the rules and regulations
     thereunder then in force, the deletion of the reference to such Holder.
 
          (ii) Each Holder of Registrable Securities as to which any
     registration is being effected agrees, by acquisition of such Registrable
     Securities, that upon receipt of any notice (a "Suspension Notice") from
     the Company of the happening of any event of the kind described in clause
     (vii) of Section 2.5(g), such Holder will forthwith discontinue such
     Holder's disposition of Registrable Securities pursuant to the registration
     statement relating to such Registrable Securities until such Holder's
     receipt of the copies of the supplemented or amended prospectus
     contemplated by clause (vii) of Section 2.5(g)[; provided, however, that in
     no event shall the period (the "Suspension Period") from the date on which
     such Holder receives a Suspension Notice to and including the date on which
     such Holder receives copies of the supplemented or amended prospectus
     contemplated by clause (vii) of Section 2.5(g) exceed twenty (20) days].
     The Company shall [use commercially reasonable efforts to] take such
     actions as are necessary to
 
                                       10
<PAGE>   14
 
     end the Suspension Period as promptly as practicable. In the event the
     Company shall give any such notice, the period referred to in clause (ii)
     of Section 2.5(g) shall be extended by a number of days equal to the number
     of days of the Suspension Period.
 
     2.6 Underwritten Offerings.
 
          (a) Underwritten Offerings in Connection with a Shelf or a Demand
     Registration.  If requested by the underwriters for any underwritten
     offering in connection with a registration pursuant to Section 2.1 or 2.2,
     the Company will enter into an underwriting agreement with such
     underwriters for such offering, such agreement (i) to be satisfactory in
     substance and form to the Company and to each of Investor and each Fidelity
     Fund (so long as it or any of its Affiliates holds Registrable Securities
     to be included in such registration) and (ii) to contain such
     representations and warranties by the Company and such Holders (subject to
     the last sentence of this Section 2.6(a)) and such other terms as are
     generally prevailing in agreements of such type, including, without
     limitation, indemnities to the effect and to the extent provided in Section
     2.8. Each of Investor and each Fidelity Fund (so long as it or any of its
     Affiliates holds Registrable Securities to be included in such
     registration) shall be a party to such underwriting agreement and may, at
     its option, require that any or all of the representations and warranties
     by, and the other agreements on the part of, the Company to and for the
     benefit of such underwriters shall also be made to and for its benefit and
     that any or all of the conditions precedent to the obligations of such
     underwriters under such underwriting agreement be conditions precedent to
     its obligations thereunder. [No Holder shall be required to make any
     representations or warranties to or agreements with the Company or the
     underwriters other than representations, warranties or agreements regarding
     such Holder's Registrable Securities and such Holder's intended method of
     distribution and any other representation required by law.]
 
          (b) Underwritten Offerings in Connection with Piggyback
     Registrations.  If the Company at any time proposes to register any of its
     equity securities under the Securities Act as contemplated by Section 2.3
     and such securities are to be distributed by or through one or more
     underwriters, the Company will, if requested by any Participating Holder
     and subject to Section 2.3(b), arrange for such underwriters to include all
     of the Registrable Equity Securities to be offered and sold by such Holder
     or Holders among the securities to be distributed by such underwriters. The
     Holders of Registrable Equity Securities to be distributed by such
     underwriters shall be parties to the underwriting agreement between the
     Company and such underwriters, provided that such agreement is reasonably
     satisfactory in substance and form to the Requisite Holders, and may, at
     their option, require that any or all of the representations and warranties
     by, and the other agreements on the part of, the Company to and for the
     benefit of such underwriters shall also be made to and for the benefit of
     such Holders and that any or all of the conditions precedent to the
     obligations of such underwriters under such underwriting agreement be
     conditions precedent to the obligations of such Holders thereunder. Any
     such Holder shall not be required to make any representations or warranties
     to or agreements with the Company or the underwriters other than
     representations, warranties or agreements regarding such Holder, such
     Holder's Registrable Equity Securities and such Holder's intended method of
     distribution and any other representation required by law.
 
     2.7 Preparation; Reasonable Investigation.  In connection with the
preparation and filing of each registration statement under the Securities Act
pursuant to this Agreement, the Company will give the Holders of Registrable
Securities to be registered under such registration statement, their
underwriters or agents, if any, and their respective counsel and accountants
reasonable access to its books and records and such opportunities to discuss the
business of the Company with its officers and the independent public accountants
who have certified its financial statements as shall be necessary, in the
opinion of such Holders' and such underwriters' or agents' respective counsel,
to conduct a reasonable investigation within the meaning of the Securities Act.
 
     2.8 Indemnification.
 
          (a) Indemnification by the Company.  The Company agrees to indemnify
     and hold harmless, to the full extent permitted by law, each Holder
     participating in an offering hereunder, its directors, officers,
 
                                       11
<PAGE>   15
 
     shareholders, employees, investment advisers, agents and Affiliates, either
     direct or indirect (and such Affiliates', directors, officers,
     shareholders, employees, investment advisers and agents), and each other
     Person, if any, who controls such Persons within the meaning of the
     Securities Act (each such Person, an "Indemnified Party"), from and against
     any losses, claims, damages, liabilities or expenses, joint or several
     (each a "Loss" and collectively, "Losses"), to which such Indemnified Party
     may become subject under the Securities Act or otherwise, insofar as such
     Losses (or actions or proceedings, whether commenced or threatened, in
     respect thereof) arise out of or are based upon any untrue statement or
     alleged untrue statement of any material fact contained in any registration
     statement under which such securities were registered under the Securities
     Act (including all documents incorporated therein by reference), any
     preliminary prospectus, final prospectus or summary prospectus contained
     therein, or any amendment or supplement thereto, or any omission or alleged
     omission to state therein a material fact required to be stated therein or
     necessary to make the statements therein not misleading, and the Company
     will reimburse such Indemnified Party for any legal or any other expenses
     reasonably incurred by it in connection with investigating or defending
     against any such Loss, action or proceeding; provided that in any such case
     the Company shall not be liable to any particular Indemnified Party to the
     extent that such Loss (or action or proceeding in respect thereof) arises
     out of or is based upon an untrue statement or alleged untrue statement or
     omission or alleged omission made in such registration statement, any such
     preliminary prospectus, final prospectus, summary prospectus, amendment or
     supplement in reliance upon and in conformity with written information
     furnished to the Company through an instrument duly executed by such
     Indemnified Party specifically for inclusion therein; and provided,
     further, that the Company shall not be liable in any such case to the
     extent it is finally determined by a court of competent jurisdiction that
     any such Loss (or action or proceeding in respect thereof) arises out of or
     is based upon an untrue statement or alleged untrue statement or omission
     or alleged omission made
 
             (i) in any such preliminary prospectus, if (A) it was the
        responsibility of such Indemnified Party to provide the Person asserting
        such Loss with a current copy of the prospectus and such Indemnified
        Party failed to deliver or cause to be delivered a copy of the
        prospectus to such Person after the Company had furnished such
        Indemnified Party with a sufficient number of copies of the same prior
        to the sale of Registrable Securities to the Person asserting such Loss
        and (B) the prospectus corrected such untrue statement or omission; or
 
             (ii) in such prospectus, if such untrue statement or omission is
        corrected in an amendment or supplement to such prospectus and such
        amendment or supplement has been delivered to the Indemnified Party
        prior to the sale of Registrable Securities to the Person asserting such
        Loss and the Indemnified Party thereafter fails to deliver the
        prospectus as so amended or supplemented prior to or concurrently with
        such sale after the Company had furnished such Indemnified Party with a
        sufficient number of copies of the same [and informed the Indemnified
        Party of the necessity to deliver such amendment or supplement to
        purchasers of securities].
 
     Such indemnity shall remain in full force and effect regardless of any
     investigation made by or on behalf of such Indemnified Party and shall
     survive the transfer of such securities by such Indemnified Party. The
     Company shall also indemnify each other Person who participates (including
     as an underwriter) in the offering or sale of Registrable Securities
     hereunder, their officers and directors and each other Person, if any, who
     controls any such participating Person within the meaning of the Securities
     Act to the same extent as provided above with respect to Indemnified
     Parties.
 
          (b) Indemnification by the Sellers.  The Company may require, as a
     condition to including any Registrable Securities in any registration
     statement filed pursuant to Section 2.3 and as a condition to indemnifying
     such sellers pursuant to this Section 2.8, that the Company shall have
     received an undertaking reasonably satisfactory to it from each prospective
     seller of such securities, to indemnify and hold harmless (in the same
     manner and to the same extent as set forth in paragraph (a) of this Section
     2.8) the Company, each director, officer, employee and agent of the
     Company, and each other Person, if any, who controls the Company within the
     meaning of the Securities Act, from and against any Losses (or actions or
     proceedings, whether commenced or threatened, in respect thereof) arising
     out of or
 
                                       12
<PAGE>   16
 
     based upon any untrue statement or alleged untrue statement of a material
     fact contained in any registration statement under which such securities
     were registered under the Securities Act (including all documents
     incorporated therein by reference), any preliminary prospectus, final
     prospectus or summary prospectus contained therein, or any amendment or
     supplement thereto, or any omission or alleged omission from such
     registration statement, preliminary prospectus, final prospectus or summary
     prospectus, or any amendment or supplement thereto required to be stated
     therein or necessary to make the statements therein not misleading, if (but
     only if) such untrue statement or alleged untrue statement or omission or
     alleged omission was made in reliance upon and in conformity with written
     information furnished to the Company through an instrument duly executed by
     such prospective seller specifically for inclusion therein; provided,
     however, that such prospective seller shall not be obligated to provide
     such indemnity to the extent that such Losses result, directly or
     indirectly, from the failure of the Company to promptly amend or take
     action to correct or supplement any such registration statement,
     prospectus, amendment or supplement based on corrected or supplemental
     information provided in writing by such prospective seller to the Company
     expressly for such purpose; and provided further, that the obligation to
     provide indemnification pursuant to this Section 2.8(b) shall be several,
     and not joint and several, among such indemnifying parties. Notwithstanding
     anything in this Section 2.8(b) to the contrary, in no event shall the
     liability of any prospective seller under such indemnity be greater in
     amount than the amount of the proceeds received by such seller upon the
     sale of its Registrable Securities in the offering to which the Losses
     relate. Such indemnity shall remain in full force and effect, regardless of
     any investigation made by or on behalf of the Company or any such director,
     officer, employee, agent or participating or controlling Person and shall
     survive the transfer of such securities by such prospective seller.
 
          (c) Notices of Claims, etc.  Promptly after receipt by an indemnified
     party of notice of the commencement of any action or proceeding involving a
     claim referred to in paragraph (a) or (b) of this Section 2.8, such
     indemnified party will, if a claim in respect thereof is to be made against
     an indemnifying party, give prompt written notice to the latter of the
     commencement of such action, provided that the failure of any indemnified
     party to give notice as provided herein shall not relieve the indemnifying
     party of its obligations under this Section 2.8, except to the extent that
     the indemnifying party is actually and materially prejudiced by such
     failure to give notice. In case any such action is brought against an
     indemnified party, the indemnifying party shall be entitled to participate
     in and to assume the defense thereof [(such assumption to constitute its
     acknowledgement of its agreement to indemnify the indemnified party with
     respect to such matters)], jointly with any other indemnifying party
     similarly notified to the extent that it may wish, with counsel reasonably
     satisfactory to such indemnified party, and after notice from the
     indemnifying party to such indemnified party of its election so to assume
     the defense thereof, the indemnifying party shall not be liable to such
     indemnified party for any legal fees or other expenses subsequently
     incurred by the latter in connection with the defense thereof other than
     reasonable costs of investigation; provided, however, that if, in such
     indemnified party's reasonable judgment, a conflict of interest between
     such indemnified and indemnifying parties may exist in respect of such
     claim, such indemnified party shall be entitled to separate counsel at the
     expense of the indemnifying party; and provided, further, that[, unless
     there exists a conflict of interest among indemnified parties,] all
     indemnified parties in respect of such claim shall be entitled to only one
     counsel or firm of counsel for all such indemnified parties. In the event
     an indemnifying party shall not be entitled, or elects not, to assume the
     defense of a claim, such indemnifying party shall not be obligated to pay
     the fees and expenses of more than one counsel or firm of counsel for all
     parties indemnified by such indemnifying party in respect of such claim,
     unless in the reasonable judgment of any such indemnified party a conflict
     of interest may exist between such indemnified party and any other of such
     indemnified parties in respect of such claim, in which event the
     indemnifying party shall be obligated to pay the fees and expenses of such
     additional counsel for such indemnified party or parties. No indemnifying
     party shall, without the consent of the indemnified party, consent to entry
     of any judgment or enter into any settlement that (i) does not include as
     an unconditional term thereof the giving by the claimant or plaintiff to
     such indemnified party of a release from all Losses in respect of such
     claim or litigation or (ii) would impose injunctive relief on such
     indemnified party. No indemnifying party shall be subject to
 
                                       13
<PAGE>   17
 
     any Losses for any settlement made without its consent, which consent shall
     not be unreasonably withheld.
 
          (d) Other Indemnification.  The provisions of this Section 2.8 shall
     be in addition to any other rights to indemnification or contribution which
     an indemnified party may have pursuant to law, equity, contract or
     otherwise.
 
          (e) Indemnification Payments.  The indemnification required by this
     Section 2.8 shall be made by periodic payments of the amount thereof during
     the course of the investigation or defense, promptly as and when bills are
     received or Losses are incurred.
 
          (f) Contribution.  If for any reason the foregoing indemnity and
     reimbursement is unavailable or is insufficient to hold harmless an
     indemnified party under paragraph (a) or (b) of this Section 2.8, then each
     indemnifying party shall contribute to the amount paid or payable by such
     indemnified party as a result of any Loss (or actions or proceedings,
     whether commenced or threatened, in respect thereof), including, without
     limitation, any legal or other expenses reasonably incurred by them in
     connection with investigating or defending any such Loss, action or
     proceeding, in such proportion as is appropriate to reflect the relative
     fault of the indemnifying party on the one hand and the indemnified party
     on the other. The relative fault shall be determined by reference to, among
     other things, whether the untrue or alleged untrue statement of a material
     fact or the omission or alleged omission to state a material fact relates
     to information supplied by the indemnifying party or the indemnified party
     and the parties' relative intent, knowledge, access to information and
     opportunity to correct or prevent such untrue statement or omission.
     Notwithstanding anything in this Section 2.8(f) to the contrary, no
     indemnifying party (other than the Company) shall be required pursuant to
     this Section 2.8(f) to contribute any amount in excess of the amount by
     which the net proceeds received by such indemnifying party from the sale of
     Registrable Securities in the offering to which the Losses of the
     indemnified parties relate exceeds the amount of any damages which such
     indemnifying party has otherwise been required to pay by reason of such
     untrue statement or omission. No person guilty of fraudulent
     misrepresentation (within the meaning of Section 11(f) of the Securities
     Act) shall be entitled to contribution from any Person who was not guilty
     of such fraudulent misrepresentation.
 
     [2.9 Liquidated Damages.
 
          (a) If the Company shall not have filed, or the SEC shall not have
     declared effective, a Shelf Registration Statement as of the Effective
     Date, the Company shall pay liquidated damages to each Holder covered or to

<PAGE>   18
 
          (d) If a stop order is imposed or if for any other reason the
     effectiveness of the Shelf Registration Statement is suspended during the
     period specified in the first sentence of Section 2.1(b), the Company shall
     pay liquidated damages to each Holder covered or to be covered by such

     based on the number of shares issuable upon exercise of the Warrant) for
     each week specified in subsection (g) below.
 
          (e) If the stop order or other suspension of effectiveness of the
     Shelf Registration Statement referred to in clause (d) above shall not have
     been cured within ninety (90) days after such stop order was imposed or the

     per $1,000 outstanding principal amount of such Registrable Debt Securities

     the case of any Warrant, $.  per share based on the number of shares

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

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 and/or any Fidelity Fund, the Company will deliver to Investor 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
and/or such Fidelity Fund, deliver to Investor and/or such Fidelity Fund a

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

and do not define or limit the provisions hereof or otherwise affect the meaning

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

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