              1978, as amended, Title 11, United States Code (the "Bankruptcy
              Code"), as the basis for its claim that registration of the offer

              Chapter 11 ("Chapter 11") of the Bankruptcy Code in the United
              States District Court for the District of Delaware. On April 20,

              number 99-21550-C-11. The Company has continued to operate its
              business and manage its properties as a debtor-in-possession
              pursuant to Sections 1107 and 1108 of the Bankruptcy Code.

              January 25, 2000 (the "Plan"). The Plan was confirmed by the
              Bankruptcy Court by order dated February 7, 2000.

               time on or after the date of issuance thereof and will expire on
               June 30, 2002.



          (b) VOTING RIGHTS.

          The voting rights of each class of voting securities listed in (a)
          above is described below:

          Old Common Stock

          Each share of the common stock of the Company issued and outstanding
          prior to the Effective Date (the "Old Common Stock") has one vote with
          respect to all matters submitted to a vote of stockholders. Cumulative
          voting is prohibited. The Old Common Stock will be canceled pursuant
          to the Plan.

          New Common Stock


          Subject to the rights described below of holders of the New Senior
          Preferred Stock and the New Class B Common Stock to elect certain
          directors, holders of shares of New Common Stock will be entitled to
          one vote per share on any matter submitted to a vote of stockholders,
          including the election of directors to fill vacancies which are not
          otherwise designated to be filled by the holders of the New Preferred
          Stock or New Class B Common Stock. Cumulative voting will be
          prohibited. The holders of the New Class B Common Stock will have the
          right, voting separately as a class, to elect one director of the
          Company during periods in which the holders of the New Senior
          Preferred Stock are not entitled to elect all five directors of the
          Company.


          New Senior Preferred Stock


          The holders of the New Senior Preferred Stock will have the right,
          voting separately as a class, to elect four of the five directors to
          the New Board of Directors of the Company; provided, that if dividends
          have not been paid with respect to the payments due on the New Senior
          Preferred Stock commencing two years after the Effective Date of the
          Plan, such holders will have the right, voting separately as a class,
          to elect all five directors to the New Board of Directors of the
          Company. Such voting rights will terminate when all such dividends
          accrued and in default have been paid in full or set apart for
          payment. The term of the fifth director so elected will terminate
          immediately upon such payment or setting apart of funds for such
          payment. Holders of the New Senior Preferred Stock will have one vote
          per share, voting together with the New Class A Common Stock (and the
          New Junior Preferred Stock and any other series of classes of Company
          stock entitled to vote with the New Class A Common Stock), on all
          matters on which holders of the New Class A Common Stock are entitled
          to vote generally.

          In addition, so long as any New Senior Preferred Stock is outstanding,
          the affirmative vote or consent of the holders of at least 75% of all
          outstanding shares of New Senior Preferred Stock, voting separately as
          a class, will be required to (i) amend, alter or repeal any provision
          of the Certificate of Incorporation or Bylaws of the Company; (ii)
          authorize or issue, or increase the authorized amount of, any
          additional class or series of stock, or any security convertible into
          stock of such class or series, ranking senior to the New Senior
          Preferred Stock as to dividends or upon liquidation, dissolution or
          winding up of the Company; (iii) waive any covenant contained in the
          Certificate of Designation for the New Senior Preferred Stock,
          provided, however, that certain specified covenants may be waived with
          the consent of 66 2/3% of all outstanding shares of New Senior
          Preferred Stock voting separately as a class; (iv) consummate any
          merger, consolidation or sale of substantially all the assets of the
          Company, or (v) effect any reclassification of the New Senior
          Preferred Stock.

<PAGE>   8
          New Junior Preferred Stock


          Holders of the New Junior Preferred Stock will have one vote per share
          (voting together with the New Class A Common Stock, the New Senior
          Preferred Stock and any other series or classes of Company stock
          entitled to vote with the New Class A Common Stock), on all matters on
          which holders of the New Class A Common Stock are entitled to vote
          generally. In exercising such voting rights, each outstanding share of
          New Junior Preferred Stock will be entitled to one vote, excluding
          shares held by the Company or any entity controlled by the Company,
          which shares shall have no voting rights. If no shares of New Senior
          Preferred Stock are outstanding, the holders of the New Junior
          Preferred Stock will have the right, voting separately as a class, to
          elect two directors to the New Board of Directors.

          In addition, so long as any New Junior Preferred Stock is outstanding,
          the affirmative vote or consent of the holders of at least 75% of all
          outstanding shares of New Junior Preferred Stock, voting separately as
          a class, will be required to waive any covenant contained in the
          Certificate of Designation for the New Junior Preferred Stock,
          provided, however, that certain specified covenants may be waived with
          the consent of 66 2/3% of all outstanding shares of New Junior
          Preferred Stock voting separately as a class.



                              INDENTURE SECURITIES

ITEM 8.   ANALYSIS OF INDENTURE PROVISIONS.


          The following analysis of Indenture provisions required under Section
          305(a)(2) of the TIA is a summary and is qualified in its entirety by
          reference to the Indenture, a copy of which is filed as an exhibit to
          this application. Capitalized terms used herein and not otherwise
          defined shall have the meanings given them in the Indenture.


          EVENTS OF DEFAULT; WITHHOLDING OF NOTICE OF DEFAULT


          The Indenture defines an Event of Default as (i) the failure by the
          Company to pay installments of interest on the Notes as and when the
          same become due and payable and the continuance of any such failure
          for 30 days, (ii) the failure by the Company to pay all or any part of
          the principal or premium, if any, on the Notes when and as the same
          become due and payable at maturity, redemption, by acceleration, or
          otherwise, including payment due by reason of a Change of Control,
          (iii) the failure by the Company or any of its Subsidiaries to observe
          or perform any other covenant, agreement, or warranty contained in the
          Security Documents, the Notes or the Indenture and, subject to certain
          exceptions, the continuance of such failure for a period of 30 days
          after written notice is given to the Company by the Trustee or to the
          Company and to the Trustee by the Holders of at least 25% in aggregate
          principal amount of the Notes outstanding, (iv) certain events of
          bankruptcy, insolvency, or reorganization in respect of the Company or
          any of its Subsidiaries, (v) a default which extends beyond any stated
          period of grace applicable thereto (including any extension thereof)
          under any mortgage, indenture, or instrument under which there is
          outstanding any Debt of the Company or any of its Subsidiaries
          aggregating in excess of $5 million or a failure to pay such Debt at
          its stated maturity, provided that a waiver by all of the lenders of
          such debt of such default shall constitute a waiver under the
          Indenture for the same period, (vi) final judgments not covered by
          insurance aggregating at least $5 million at any one time rendered
          against the Company or any of its Subsidiaries and not stayed, bonded
          or discharged within 60 days, or (vii) any of the Security Documents
          not being in full force and effect or ceasing to give the Trustee a
          perfected security interest in, and Lien on, the Collateral (except as
          the result of a release effected pursuant to the Indenture or where no
          material adverse effect to the holders of the Notes would result). The
          Indenture provides that if a default occurs and is continuing and if
          it is known to the Trustee, the Trustee must, within 90 days after the
          occurrence of such default, give to the Holders notice of such
          default; provided, that, except in the case of default in payment of
          principal of, premium, if any, or interest on the Notes, the Trustee
          will be protected in withholding such notice if it in good faith
          determines that the withholding of such notice is in the interest of
          the holders of the Notes.



                                       8
<PAGE>   9

          If an Event of Default occurs and is continuing (other than an Event
          of Default specified in clause (iv), above, relating to the Company or
          its Subsidiaries), then in every such case, unless the principal of
          all of the Notes shall have already become due and payable, either the
          Trustee or the Holders of 25% in aggregate principal amount of Notes
          then outstanding, by notice in writing to the Company (and to the
          Trustee if given by Holders) (an "Acceleration Notice"), may declare
          all principal of the Notes, and accrued interest thereon, to be due
          and payable immediately. If an Event of Default specified in clause
          (iv), above, relating to the Company or its Subsidiaries occurs, all
          principal and accrued interest thereon will be immediately due and
          payable on all outstanding Notes without any declaration or other act
          on the part of the Trustee or the Holders. The Holders of not less
          than 75% in aggregate principal amount of Notes generally are
          authorized to waive such declarations of acceleration if (a) the
          Company has paid or deposited with the Trustee a sum sufficient to pay
          all accrued and unpaid interest on the Notes, the principal, and
          premium, if any, of any Notes which would become due otherwise than by
          such acceleration and certain other items, and (b) all existing Events
          of Default, other than the non-payment of the principal of, premium,
          if any, and interest on the Notes which have become due solely by such
          acceleration, have been cured or waived. However, no such waiver shall
          be effective for any Event of Default or event which with notice or
          lapse of time or both would be an Event of Default with respect to any
          covenant or provision which cannot be modified or amended without the
          consent of (x) 75% in aggregate principal amount of the Notes, or (y)
          the affected Holder of each of the outstanding Notes, unless (x) 75%
          in aggregate principal amount of the Notes, or (y) all such affected
          Holders, respectively, agree, in writing, to waive such Event of
          Default or event. No such waiver shall cure or waive any subsequent
          default or impair any right consequent thereon.

          Prior to the declaration of acceleration of the Notes, the Holders of
          66 2/3% in aggregate principal amount of the Notes at the time
          outstanding may waive on behalf of all the Holders any default or
          potential default, except a default or potential default (i) in the
          payment of principal of, premium, if any, or interest on any Note not
          yet cured, (ii) which arises because of a violation of the Indenture
          provision regarding amendments, supplements and waivers with the
          consent of Holders, or (iii) with respect to any covenant or provision
          which cannot be modified or amended without the consent of the Holder
          of each outstanding Note affected or 75% in aggregate principal amount
          of the Notes at the time outstanding, as the case may be; provided,
          however, that such a default may be waived by the consent of Holders
          of each outstanding Note affected or 75% in aggregate principal amount
          of the Notes outstanding, as the case may be.

          Subject to the provisions of the Indenture relating to the duties of
          the Trustee, the Trustee is under no obligation to exercise any of its
          rights or powers under the Indenture at the request, order, or
          direction of any of the Holders, unless such Holders have offered to
          the Trustee reasonable security or indemnity. Subject to all
          provisions of the Indenture and applicable law, the Holders of 66 2/3%
          in aggregate principal amount of the Notes at the time outstanding
          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.


          AUTHENTICATION AND DELIVERY OF THE NOTES; APPLICATION OF PROCEEDS


          A Note shall not be valid until an authorized signatory of the Trustee
          manually signs the certificate of authentication on the Note, but such
          signature shall be conclusive evidence that the Note has been
          authenticated pursuant to the terms of the Indenture.

          The Trustee shall authenticate Notes for original issue in the
          aggregate principal amount of up to $200,000,000 upon a written order
          of the Company in the form of an Officers' Certificate. The Officers'
          Certificate shall specify the amount of Notes to be authenticated and
          the date on which the Notes are to be authenticated. The aggregate
          principal amount of Notes outstanding at any time under the Indenture
          may not exceed $200,000,000. Upon the written order of the Company in
          the form of an Officers' Certificate, the Trustee shall authenticate
          Notes in substitution of Notes originally issued to reflect any name
          change of the Company.



                                       9
<PAGE>   10

          The Trustee may appoint an authenticating agent acceptable to the
          Company to authenticate Notes. Unless otherwise provided in the
          appointment, an authenticating agent may authenticate Notes whenever
          the Trustee may do so. An authenticating agent has the same rights as
          a Registrar, a Paying Agent or a co-Registrar appointed under the
          Indenture to deal with the Company, any Guarantor, any Affiliate, or
          any of their respective Subsidiaries.

          Notes shall be issuable only in registered form without coupons in
          denominations of $1,000 and any integral multiple thereof.

          The Notes will be issued pursuant to the Plan; there will be no
          proceeds from the issuance of the Notes.


          RELEASE OR RELEASE AND SUBSTITUTION OF PROPERTY SUBJECT TO THE LIEN OF
          THE INDENTURE


          The Notes will be secured by a lien on substantially all of the assets
          of the Company, other than Inventory and Receivables (the
          "Collateral"). The liens securing the Extended DIP Facility, the Post
          Confirmation Credit Facility and certain other indebtedness will be
          senior to the lien securing the Notes.

          Under certain circumstances specified in the Indenture, the Company
          may dispose of Collateral without requesting or receiving the consent
          of the Trustee, and, in certain circumstances, such disposal can be
          made free from the security interests. In addition, the Trustee can
          release all or part of the Collateral from the security interests,
          upon request by the Company, if no Event of Default has occurred and
          is continuing, and if one of the following conditions is met: (i) the
          Collateral to be released will be used within five business days
          either to make redemptions or purchases of Notes which will be
          delivered to the Trustee for cancellation, (ii) the Collateral is to
          be released in connection with an Asset Sale in compliance with the
          Asset Sale provisions, (iii) all of the conditions precedent to the
          termination of the security document under which the lien in the
          Collateral to be released was created, or to the release of such
          Collateral from the lien created by such security document, as set
          forth in such security document, have been satisfied, (iv) holders of
          not less than 75% in principal amount of the then outstanding Notes
          have consented in writing to such release of Collateral from the
          security interests; (v) the Collateral to be released secures debt or
          other obligations that constitute certain specified types of First
          Lien Debt and the Company has satisfied the requirements for obtaining
          subordination of the security interests therein and such Collateral is
          or will be encumbered by a lien permitted under the Indenture; or (vi)
          the release is required pursuant to or in order to effect compliance
          with the Plan or a Plan Order. The Company must also deliver any
          certificate or opinion required by the TIA. The Company can also
          request the Trustee to execute a subordination agreement, in lieu of
          releasing any Collateral, with respect to such Collateral.

          Upon satisfaction and discharge of the Indenture, the Trustee's lien
          on the Collateral will be released.


          SATISFACTION AND DISCHARGE OF THE INDENTURE


          The Indenture ceases to be of further effect as to all outstanding
          Notes (except as to (i) rights of registration of transfer,
          substitution, and exchange of Notes and the Company's right of
          optional redemption, (ii) rights of Holders to receive payments of
          principal of, premium, if any, and interest on the Notes and any other

          only if certain conditions are satisfied, including delivery by the
          Company to the Trustee of opinions of outside counsel acceptable to
          the Trustee (who may be outside counsel to the Company) to the effect
          that (i) the defeasance and discharge will not be deemed, or result
          in, a taxable event for Federal income tax purposes, with respect to
          the Holders, and (ii) all conditions precedent have been complied
          with. The Indenture will not be discharged if, among other things, (i)
          an Event of Default relating to certain events of bankruptcy,
          insolvency or reorganization of the Company shall have occurred and be
          continuing on the date of such deposit or at any time in the period
          ending on the 91st day after the date of such deposit, or (ii) the

          default under, the Indenture or any other material agreement or
          instrument to which the Company, the Guarantors, or any of their
          Subsidiaries is a party or by which its properties is bound. The
          Company will be deemed to have paid and discharged the entire
          indebtedness on all of the outstanding Notes when (i) all outstanding
          Notes have been delivered to the Trustee for cancellation, or (ii) the
          Company has paid or caused to be paid the principal of and interest on
          the Notes.


          EVIDENCE TO BE FURNISHED TO TRUSTEE AS TO COMPLIANCE WITH CONDITIONS
          AND COVENANTS


          The Company is required to furnish to the Trustee, within 60 days
          after the end of each fiscal quarter or 105 days after the end of a
          fiscal quarter that is also the end of a fiscal year, an officers'
          certificate to the effect that such officers have conducted or
          supervised a review of the activities of the Company and its
          Subsidiaries and of performance under the Indenture and that, to the
          best of such officers' knowledge, based on their review, the Company
          and its Subsidiaries have fulfilled all of their obligations under the
          Indenture or, if there has been a default, specifying each default
          known to them, its nature and its status. The Company is also required
          to notify the Trustee of any changes in the composition of the Board
          of Directors of the Company or any of its Subsidiaries or of any
          amendment to the charter or bylaws of the Company or any of its
          Subsidiaries.

          The Company will be required to deliver to the Trustee within 105 days
          after the end of each of its fiscal years a written report of a firm
          of independent certified accountants with an established national
          reputation stating that in conducting their audit for such fiscal
          year, nothing has come to their attention that caused them to believe
          that the Company or any of its Subsidiaries was not in compliance with
          certain provisions of the Indenture.

          The Company shall, so long as any of the Notes are outstanding,
          deliver to the Trustee immediately upon becoming aware of any Default
          or Event of Default under the Indenture, an officers' certificate
          specifying such Default or Event of Default and what action the
          Company is taking or proposes to take with respect thereto.

          The Company and each of its Subsidiaries, where applicable, shall
          deliver to the Trustee and to each Holder, within 15 days after it
          files them with the Commission, copies of all reports and information
          that the Company is required to file with the Commission pursuant to
          Section 13 or 15(d) of the Exchange Act.

          Concurrently with the reports delivered pursuant to the preceding
          paragraph, the Company shall deliver to the Trustee and to each Holder
          annual and quarterly financial statements with appropriate footnotes
          of the Company and its Subsidiaries, all prepared and presented in a
          manner substantially consistent with those of the Company required by
          the preceding paragraph.


ITEM 9.   OTHER OBLIGORS.


          The Company's obligations under the Indenture will be guaranteed by
          certain Subsidiaries of the Company and secured by a pledge of certain
          of such Subsidiaries' assets.

         INDENTURE, dated as of _________ ___, 2000, between TRANSTEXAS GAS
CORPORATION, a Delaware corporation (the "Company"), and FIRSTAR BANK, N.A., as
Trustee.

         Each party hereto agrees as follows for the benefit of each other party
and for the equal and ratable benefit of the Holders of the Company's 15% Senior
Secured Notes due 2005:



                                    ARTICLE I

                   DEFINITIONS AND INCORPORATION BY REFERENCE


         Section 1.1  Definitions.


         "Acceleration Notice" shall have the meaning specified in Section 6.2.

         "Accounts" means "accounts," as that term is defined in Article 9 of
the Uniform Commercial Code as in effect in the State of New York, together with
the proceeds and products thereof.

         "Adjusted Consolidated Net Income" of any Person for any period means
the net income (loss) of such Person and its consolidated Subsidiaries for such
period, determined in accordance with GAAP, excluding (without duplication) (i)
all extraordinary gains (but not losses), (ii) the net income, if positive, of
any other Person, other than a consolidated Subsidiary, in which such Person or
any of its consolidated Subsidiaries has an interest, except to the extent of
the amount of any dividends or distributions actually paid in cash to such
Person or a consolidated Subsidiary of such Person during such period, (iii) the
net income, if positive, of any Person acquired in a pooling of interests
transaction for any period prior to the date of such acquisition, and (iv) the
net income, if positive, of any Subsidiary of such Person to the extent that the
declaration or payment of dividends or similar distributions is not at the time
permitted by operation of the terms of its charter or any agreement, instrument,
judgment, decree, order, statute, rule, or governmental regulation applicable to
such Subsidiary.

         "Adjusted Consolidated Tangible Assets" means (without duplication), as
of the date of determination, (A) the sum of (i) discounted future net cash
flows from proved oil and gas reserves of the Company Entities, calculated in
accordance with SEC guidelines (before any state or federal income tax), as
estimated in a Reserve Report as of a date no earlier than the Company's most
recent fiscal year end (or, if such Reserve Report is unavailable, or if the
date of determination is after the end of the first fiscal quarter of the most
recent fiscal year of the Company, as estimated by the Company engineers on the
same basis as of a date no earlier than the end of the most recent fiscal
quarter, which estimates shall be confirmed in writing by a report by nationally
recognized independent petroleum engineers in accordance with SEC guidelines in
the event of a Material Change), (ii) the Net Working Capital of the Company on
a date no earlier than the date of the Company's latest consolidated annual or
quarterly financial statements, and (iii) with respect to all other tangible
assets (which are deemed to include mineral lease-hold interests) of the Company
Entities, the net book value of such other tangible assets on a date no earlier
than the date of the Company's latest consolidated annual or quarterly financial
statements, minus (B) minority interests and, to the extent not otherwise taken
into account in determining Adjusted Consolidated Tangible Assets, any gas
balancing liabilities of the Company Entities. In addition to, but without
duplication of the foregoing, for purposes of this definition, "Adjusted
Consolidated Tangible Assets" shall be calculated after giving effect, on a pro
forma basis, to (1) any Permitted Investment, on or before the date of the
transaction giving rise to the need to calculate Adjusted Consolidated Tangible
Assets (the "Assets Transaction Date"), in any other Person that, as a result of
such investment, becomes a Subsidiary of the Company, (2) the acquisition, on or



                                       1
<PAGE>   9

before the Assets Transaction Date (by merger, consolidation, or purchase of
stock or assets), of any business or assets, including, without limitation,
Permitted Investments, and (3) any sales or other dispositions of assets (other
than sales of Hydrocarbons or other mineral products in the ordinary course of
business) occurring on or prior to the Assets Transaction Date. For purposes of
calculating the ratio of the Company's Adjusted Consolidated Tangible Assets to
total consolidated Debt of the Company Entities, Debt of a Subsidiary that is
not a wholly owned Subsidiary of the Company (which Debt is non-recourse to the
Company or any of its other Subsidiaries or any of their assets) shall be
included only to the extent of the Company's pro rata ownership interest in such
Subsidiary.

         "Adjusted Net Assets" of a Guarantor means the lesser of (a) the amount
by which the Guarantor's property, at a fair valuation, exceeds the sum of its
debts (including unliquidated or contingent debts), (b) the amount by which the
present fair salable value of the Guarantor's assets exceeds the amount that
will be required to pay its probable liability on its existing debts as they
become absolute and matured, (c) the amount by which the Guarantor's assets
exceed the maximum amount that would constitute unreasonably small capital for
its business, or (d) the amount by which the Guarantor's assets exceed the
amount that such Guarantor should reasonably retain to pay its debts (including
unliquidated or contingent debts) as they mature.

         "Affiliate" means, with respect to any specified Person, (i) any other
Person directly or indirectly controlling or controlled by, or under direct or
indirect common control with, such specified Person, (ii) any director or
controlling shareholder of such other Person, or (iii) any officer of such
specified Person or such other Person. For purposes of this definition, the term
"control" means (a) the power to direct the management and policies of a Person,
directly or through one or more intermediaries, whether through the ownership of
voting securities, by contract, or otherwise, or (b) without limiting the
foregoing, the beneficial ownership of 10% or more of the voting power of the
voting common equity of such Person (on a fully diluted basis) or of warrants or
other rights to acquire such equity (regardless of whether presently
exercisable).

         "Affiliate Transaction" means, with respect to any Person, any
transaction or series of related transactions with any Affiliate of such Person
(including, without limitation: (i) the sale, lease, transfer or other
disposition of properties, assets or securities to such Affiliate, (ii) the
purchase or lease of any property, assets or securities from such Affiliate
(iii) an Investment in such Affiliate and (iv) entering into or amending any
contract or agreement with or for the benefit of any such Affiliate.

         "Agent" means any Registrar, Paying Agent or co-Registrar.

         "Allowed" shall have the meaning specified in the Plan.

         "Allowed Claim" shall have the meaning specified in the Plan.

         "Appraisal" means, when used with respect to the valuation of any
property, an appraisal prepared by an Appraiser as to the Appraised Value of
such property.

         "Appraised Value" means, with respect to any property at any date, the
then current fair market value of such property as set forth in the most recent
Appraisal.

         "Appraiser" means an independent appraiser of national recognition
qualified to appraise the property appraised.

         "Asset Sale" means any direct or indirect conveyance, sale, transfer or
other disposition (including through damage or destruction for which Insurance
Proceeds are paid or by condemnation), in one transaction



                                       2
<PAGE>   10

or a series of related transactions, of any of the properties, businesses or
assets of the Company or any Subsidiary of the Company, whether owned on the
Issue Date or thereafter acquired; provided, however, that "Asset Sale" shall
not include (i) any disposition of Inventory or Receivables, (ii) any pledge or
disposition of assets (if such pledge or disposition would otherwise constitute
an Asset Sale) to the extent and only to the extent that it results in the
creation of a Permitted Lien (other than the creation of a Permitted Lien in
connection with a Drilling Production Payment or a Drilling Program, which in
either case shall be treated as an Asset Sale hereunder), (iii) any issuance or
disposition of securities that is made pursuant to and in accordance with the
Plan or a Plan Order, or (iv) the Davis Transactions.

         "Attributable Debt" in respect of a Sale and Leaseback Transaction
means, at the time of determination, the present value (discounted at the rate
of interest implicit in such transaction, determined in accordance with GAAP,
or, in the event that such rate of interest is not reasonably determinable,
discounted at the rate of interest borne by the Notes) of the obligation of the
lessee for net rental payments during the remaining term of the lease included
in such Sale and Leaseback Transaction (including any period for which such
lease has been extended or may, at the option of the lessor, be extended).

         "Bankruptcy Code" means Title 11, United States Code, as amended from

of the Board of Directors of such Person.

         "Board Resolution" means, with respect to any Person, a duly adopted

         "Borrowing Base" means, as of any date, an amount equal to the sum of
(a) 85% of the book value of all Accounts owned by the Company and its
Subsidiaries (excluding any Accounts that are more than 90 days past due, less
(without duplication) the allowance for doubtful accounts attributable to such
current Accounts) calculated on a consolidated basis and in accordance with
GAAP, and (b) 70% of the current market value of all Inventory owned by the
Company and its Subsidiaries as of such date. To the extent that information is
not available as to the amount of Accounts as of a specific date, the Company
may utilize, to the extent reasonable, the most recent available information for
purposes of calculating the Borrowing Base.

         "Business Day" means a day that is not a Legal Holiday.

         "Capital Expenditures" of a Person means expenditures (whether paid in
cash or accrued as a liability) by such Person or any of its Subsidiaries that,

accounting practices.

at any time may require a Paying Agent to distribute all assets held by it to
the Trustee and account for any assets disbursed and the Trustee may at any time
during the continuance of any payment Default, upon written request to a Paying
Agent, require such Paying Agent to distribute all assets held by it to the
Trustee and to account for any assets distributed. Upon distribution to the
Trustee of all assets that shall have been delivered by the Company to the
Paying Agent, the Paying Agent (if other than the Company, or any Affiliate of
the Company) shall have no further liability for such assets.

         Section 2.5 Noteholder Lists. The Trustee shall preserve in as current
a form as is reasonably practicable the most recent list available to it of the
names and addresses of Holders. If the Trustee is not the Registrar, the Company
shall furnish to the Trustee on or before the third Business Day preceding each
Interest Payment Date and at such other times as the Trustee may request in
writing a list in such form and as of such date as the Trustee reasonably may
require of the names and addresses of Holders.

         Section 2.6 Transfer and Exchange. When Notes are presented by a
Holder to the Registrar with a request to register the transfer of the Notes or
to exchange such Notes for an equal principal amount of Notes of other
authorized denominations, the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transactions are met;
provided, however, that the Notes so presented


                                       26
<PAGE>   34
have been duly endorsed or accompanied by a written instruction of transfer in
form satisfactory to the Registrar duly executed by such Holder or by his
attorney, duly authorized in writing. The signature of the Holder or his duly
authorized attorney must be guaranteed by a participant in the Securities
Transfer Agents Medallion Program, the Stock Exchanges Medallion Program or the
New York Stock Exchange Inc. Medallion Signature Program. To permit
registrations of transfers and exchanges, the Company shall execute and the
Trustee shall authenticate Notes at the Registrar's request. All Notes issued
upon any registration of transfer or exchange of Notes shall be legal, valid and
binding obligations of the Company, evidencing the same debt, and entitled to
the same benefits under this Indenture, as the Notes surrendered upon such
registration of transfer or exchange.

         No service charge shall be made to a Holder for any registration of
transfer or exchange, but the Company or the Trustee may require payment of a
sum sufficient to cover any transfer tax or similar governmental charge payable
in connection therewith (other than any such transfer taxes or similar
governmental charge payable upon exchange (without transfer to another Person)
pursuant to Sections 2.10, 3.7, 4.14 and 9.5 of this Indenture).

         The Company shall not be required (i) to issue, register the transfer
of or exchange Notes during a period beginning at the opening of business 15
days before the day of any selection of Notes for redemption under Section 3.2
hereof and ending at the close of business on the day of selection, (ii) to
register the transfer of or exchange any Note so selected for redemption in
whole or in part, except the unredeemed portion of any Note being redeemed in
part, or (iii) to register the transfer of or exchange a Note between a record
date and the next succeeding interest payment date.

         Prior to due presentment for the registration of a transfer of any
Note, the Trustee, any Agent and the Company may deem and treat the Person in
whose name any Note is registered as the absolute owner of such Note for all
purposes, and neither the Trustee, any Agent nor the Company shall be affected
by notice to the contrary.

         Section 2.7 Replacement Notes. If a mutilated Note is surrendered to
the Trustee or if the Holder of a Note claims and submits an affidavit or other
evidence, satisfactory to the Company and the Trustee, to the Trustee to the
effect that the Note has been lost, destroyed or wrongfully taken, the Company
shall issue and the Trustee shall authenticate a replacement Note if the
Trustee's requirements are met. If required by the Trustee or the Company, such
Holder must provide an indemnity bond or other indemnity, sufficient in the
judgment of both the Company and the Trustee, to protect the Company, the
Trustee or any Agent from any loss which any of them may suffer if a Note is
replaced. The Company and the Trustee may charge such Holder for its reasonable,
out-of-pocket expenses in replacing a Note.

         Every replacement Note is an additional obligation of the Company.

         Section 2.8 Outstanding Notes. Notes outstanding at any time are all
the Notes that have been authenticated by the Trustee except those canceled by
it, those delivered to it for cancellation, and those described in this Section
2.8 as not outstanding. A Note does not cease to be outstanding because the
Company or an Affiliate of the Company holds the Note, except as provided in
Section 2.9.

         If a Note is replaced pursuant to Section 2.7 (other than a mutilated
Note surrendered for replacement), it ceases to be outstanding unless the
Trustee receives proof satisfactory to it that the replaced Note is held by a
bona fide purchaser. A mutilated Note ceases to be outstanding upon surrender of
such Note and replacement thereof pursuant to Section 2.7.


                                       27
<PAGE>   35
         If on a Redemption Date or the Maturity Date the Paying Agent (other
than the Company or an Affiliate of the Company) holds U.S. Legal Tender or U.S.
Government Obligations sufficient to pay all of the principal and interest due
on the Notes payable on that date, then on and after that date such Notes cease
to be outstanding and interest on them ceases to accrue.

         Section 2.9 Treasury Notes. In determining whether the Holders of the
required principal amount of Notes have concurred in any direction, amendment,
supplement, waiver or consent, Notes owned by the Company and Affiliates of the
Company shall be disregarded, except that, for the purposes of determining
whether the Trustee shall be protected in relying on any such direction,
amendment, supplement, waiver or consent, only Notes that the Trustee knows or
has reason to know are so owned shall be disregarded.

         Section 2.10 Temporary Notes. Until definitive Notes are ready for
delivery, the Company may prepare and the Trustee shall authenticate temporary
Notes. Temporary Notes shall be substantially in the form of definitive Notes
but may have variations that the Company reasonably and in good faith considers
appropriate for temporary Notes. Without unreasonable delay, the Company shall
prepare and the Trustee shall authenticate definitive Notes in exchange for
temporary Notes. Until so exchanged, the temporary Notes shall in all respects
be entitled to the same benefits under this Indenture as permanent Notes
authenticated and delivered hereunder.

         Section 2.11 Cancellation. The Company at any time may deliver Notes
to the Trustee for cancellation. The Registrar and the Paying Agent shall
forward to the Trustee any Notes surrendered to them for transfer, exchange or
payment. The Trustee, or at the direction of the Trustee, the Registrar or the
Paying Agent (other than the Company or any Affiliate of the Company), and no
one else, shall cancel and, at the written direction of the Company, shall
dispose of all Notes surrendered for transfer, exchange, payment or
cancellation. Subject to Section 2.7, the Company may not issue new Notes to
replace Notes it has paid or delivered to the Trustee for cancellation. No Notes
shall be authenticated in lieu of or in exchange for any Notes canceled as
provided in this Section 2.11, except as expressly permitted in the form of Note
and as permitted by this Indenture.

         Section 2.12 Defaulted Interest. Interest on any outstanding Note
which is payable, and is punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the Person in whose name that Note (or one or more
predecessor Notes) is registered at the close of business on the Record Date for
such interest.

         Any interest on any outstanding Note which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date plus, to the
extent lawful, any interest payable on the defaulted interest (herein called
"Defaulted Interest") shall forthwith cease to be payable to the registered
Holder on the relevant Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Notes (or their respective
         predecessor Notes) are registered at the close of business on a Special
         Record Date for the payment of such Defaulted Interest, which shall be
         fixed in the following manner. The Company shall notify the Trustee in
         writing of the amount of Defaulted Interest proposed to be paid on each
         Note and the date of the proposed payment, and at the same time the
         Company shall deposit with the Trustee an amount of money equal to the
         aggregate amount proposed to be paid in respect of such Defaulted
         Interest or shall make arrangements satisfactory to the Trustee for
         such deposit prior to the date of the proposed payment, such money when
         deposited to be held in trust for the benefit of the Persons entitled
         to such Defaulted Interest as provided in this clause (1). Thereupon
         the Trustee shall fix a Special Record Date for the payment of such
         Defaulted


                                       28
<PAGE>   36
         Interest which shall be not more than 15 days and not less than 10 days
         prior to the date of the proposed payment and not less than 10 days
         after the receipt by the Trustee of the notice of the proposed payment.
         The Trustee shall promptly notify the Company of such Special Record
         Date and, in the name and at the expense of the Company, shall cause
         notice of the proposed payment of such Defaulted Interest and the
         Special Record Date therefor to be mailed, first-class postage prepaid,
         to each Holder at his address set forth upon the registry books of the
         Company on the 10th day prior to such Special Record Date. The Trustee
         may, in its discretion, in the name and at the expense of the Company,
         cause a similar notice to be published at least once in a newspaper,
         customarily published in the English language on each Business Day and
         of general circulation in the Borough of Manhattan, the City of New
         York, but such publication shall not be a condition precedent to the
         establishment of such Special Record Date. Notice of the proposed
         payment of such Defaulted Interest and the Special Record Date therefor
         having been mailed as aforesaid, such Defaulted Interest shall be paid
         to the Persons in whose names the Notes (or their respective
         predecessor Notes) are registered on such Special Record Date and shall
         no longer be payable pursuant to the following clause (2).

                  (2) The Company may make payment of any Defaulted Interest in
         any other lawful manner not inconsistent with the requirements of any
         securities exchange on which the Notes may be listed, and upon such
         notice as may be required by such exchange, if, after notice given by
         the Company to the Trustee of the proposed payment pursuant to this
         clause accompanied by an Opinion of Counsel stating that the manner of
         payment complies with this clause, such manner shall be deemed
         practicable by the Trustee.

         Subject to the foregoing provisions of this Section, each Note
delivered under this Indenture upon transfer of or in exchange for or in lieu of
any other Note shall carry the rights to interest accrued and unpaid, and to
accrue, which were carried by such other Note.

         Section 2.13 Computation of Interest. Interest on the Notes will be
computed on the basis of a 360-day year consisting of twelve 30-day months.


                                   ARTICLE III

                                   REDEMPTION

         Section 3.1 Right of Redemption. Redemption of Notes, as permitted or
required by any provision of this Indenture, shall be made in accordance with
such provision and this Article III. The Notes may be redeemed at the election
of the Company, as a whole or from time to time in part, at any time on or after
the Issue Date, at the applicable Redemption Prices specified in Paragraph 5 of
the form of Note attached as Exhibit A hereto, set forth therein under the
caption "Optional Redemption," in each case, including accrued and unpaid
interest to the Redemption Date.

         Section 3.2 Notices to Trustee. If the Company elects to redeem Notes
pursuant to Paragraph 5 of the Notes, it shall notify the Trustee in writing of
the Redemption Date and the principal amount of Notes to be redeemed and whether
it wants the Trustee to give notice of redemption to the Holders.

         The Company shall give each notice to the Trustee provided for in this
Section 3.2 at least 30 days before the Redemption Date (unless a shorter notice
shall be satisfactory to the Trustee).


                                       29
<PAGE>   37

        Section 3.3 Selection of Notes to Be Redeemed. If less than all of the
Notes are to be redeemed pursuant to Paragraph 5 thereof, the Trustee shall
select the Notes to be redeemed pro rata, by lot or in such other manner as in
its sole discretion it deems appropriate and fair, and in such manner as
complies with any applicable legal and stock exchange requirements.

        The Trustee shall make the selection from the Notes outstanding and not
previously called for redemption and shall promptly notify the Company in
writing of the Notes selected for redemption and, in the case of any Note
selected for partial redemption, the principal amount thereof to be redeemed.
Notes in denominations of $1,000 may be redeemed only in whole. The Trustee may
select for redemption portions (equal to $1,000 or any integral multiple
thereof) of the principal of Notes that have denominations larger than $1,000.
Provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption.

        Section 3.4 Notice of Redemption. At least 30 days but not more than
60 days before a Redemption Date, the Company shall mail a notice of redemption
by first class mail, postage prepaid, to the Trustee and each Holder whose Notes
are to be redeemed. At the Company's request, the Trustee shall give the notice
of redemption in the Company's name and at the Company's expense. Each notice of
redemption shall identify the Notes to be redeemed and shall state the following
and such other matters as the Trustee shall deem proper:

               (1) the Redemption Date;

               (2) the Redemption Price, including the amount of accrued and
                   unpaid interest to be paid upon such redemption;

               (3) the name, address and telephone number of the Paying Agent;

               (4) that Notes called for redemption must be surrendered to the
                   Paying Agent at the address specified in such notice to
                   collect the Redemption Price;

               (5) that, unless the Company defaults in its obligation to
                   deposit U.S. Legal Tender with the Paying Agent in accordance
                   with Section 3.6, interest on Notes called for redemption
                   ceases to accrue on and after the Redemption Date and the
                   only remaining right of the Holders of such Notes is to
                   receive payment of the Redemption Price, including accrued
                   and unpaid interest, upon surrender to the Paying Agent of
                   the Notes called for redemption and to be redeemed;

               (6) if any Note is being redeemed in part, the portion of the
                   principal amount, equal to $1,000 or any integral multiple
                   thereof, of such Note that will not be redeemed and that,
                   after the Redemption Date and upon surrender of such Note, a
                   new Note or Notes in aggregate principal amount equal to the
                   unredeemed portion thereof will be issued;

               (7) if less than all the Notes are to be redeemed, the
                   identification of the particular Notes (or portion thereof)
                   to be redeemed, as well as the aggregate principal amount of
                   such Notes to be redeemed and the aggregate principal amount
                   of Notes to be outstanding after such partial redemption;

               (8) the CUSIP number of the Notes to be redeemed; and




                                       30
<PAGE>   38

               (9) that the notice is being sent pursuant to this Section 3.4
                   and pursuant to the redemption provisions of Paragraph 5 of
                   the Notes.

        Section 3.5 Effect of Notice of Redemption. Once notice of redemption
is mailed in accordance with Section 3.4, Notes called for redemption become due
and payable on the Redemption Date and at the Redemption Price, including
accrued and unpaid interest. Upon surrender to the Trustee or Paying Agent, such
Notes called for redemption shall be paid at the Redemption Price, including
interest, if any, accrued and unpaid on the Redemption Date; provided, however,
that if the Redemption Date is after a regular Record Date and on or prior to
the Interest Payment Date, the accrued interest through the date of redemption
shall be payable to the Holder of the redeemed Notes registered on the relevant
Record Date; and provided, further, that if a Redemption Date is a Legal
Holiday, payment shall be made on the next succeeding Business Day and no
interest shall accrue for the period from such Redemption Date to such
succeeding Business Day.

        Upon compliance by the Company with the provisions of this Article III,
including but not limited to Section 3.6, interest on the Notes called for
redemption will cease to accrue on and after the Redemption Date, regardless of
whether such Notes are presented for payment.

        Section 3.6 Deposit of Redemption Price. On or prior to the Redemption
Date, the Company shall deposit with the Paying Agent (other than the Company or
an Affiliate of the Company) U.S. Legal Tender sufficient to pay the Redemption
Price of, including accrued and unpaid interest on, all Notes to be redeemed on
such Redemption Date (other than Notes or portions thereof called for redemption
on that date that have been delivered by the Company to the Trustee for
cancellation). The Paying Agent shall promptly return to the Company any U.S.
Legal Tender so deposited which is not required for that purpose upon the
written request of the Company.

        If the Company complies with the preceding paragraph and the other
provisions of this Article III, interest on the Notes to be redeemed will cease
to accrue on the applicable Redemption Date, regardless of whether such Notes
are presented for payment. Notwithstanding anything herein to the contrary, if
any Note surrendered for redemption in the manner provided in the Notes shall
not be so paid upon surrender for redemption because of the failure of the
Company to comply with the preceding paragraph, interest shall continue to
accrue and be paid from the Redemption Date until such payment is made on the
unpaid principal and, to the extent lawful, on any interest not paid on such
unpaid principal, in each case at the rate and in the manner provided in Section
4.1 and the Note.

        Section 3.7 Notes Redeemed in Part. Upon surrender of a Note that is
to be redeemed in part, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder, without service charge, a new Note or
Notes equal in principal amount to the unredeemed portion of the Note
surrendered.


                                   ARTICLE IV

                                    COVENANTS

        Section 4.1 Payment of Notes. The Company shall pay the principal of
and interest on the outstanding Notes on the dates and in the manner provided in
the Notes to the Trustee at its New York agent's office unless otherwise
instructed in writing by the Trustee. An installment of principal of or interest

Paying Agent (other than the Company or an Affiliate of the Company) holds for
the benefit of the Holders, on or before 12:00 noon, New York, New York time on
that date, U.S. Legal Tender deposited and designated for and sufficient to pay
the installment.



                                       31
<PAGE>   39

The Company shall pay any and all amounts, including without limitation,
liquidated damages, if any, on the dates and in the manner required under the
Registration Rights Agreement.

        The Company shall pay interest on overdue principal and on overdue
installments of interest at the rate specified in the Notes compounded
semi-annually, to the extent lawful.

        Notwithstanding anything to the contrary contained in this Indenture,
the Company or the Trustee may, to the extent required by law, deduct or
withhold income or other similar taxes imposed by the United States of America
from principal, premium or interest payments on the Notes.

        Section 4.2 Maintenance of Office or Agency. The Company shall maintain
in the Borough of Manhattan in the City of New York, New York, an office or
agency where Notes may be presented or surrendered for payment, where Notes may
be surrendered for registration of transfer or exchange and where notices and
demands to or upon the Company in respect of the Notes and this Indenture may be
served. The Company shall give prior written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the address of the
Trustee set forth in Section 14.2.

        The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan in the City of New York, New York, for such purposes. The Company
shall give prior 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.
The Company hereby initially designates the corporate trust office of the
Trustee in the Borough of Manhattan in the City of New York, New York, as such
office of the Company.

        Section 4.3 Limitation on Restricted Payments. The Company shall not,
and shall not permit any of its Subsidiaries to, directly or indirectly, make
any Restricted Payment.

        Section 4.4 Corporate Existence. Subject to Article V, the Company shall

and effect its corporate existence and the corporate or other existence of each
of its Subsidiaries in accordance with the respective organizational documents

of the Company and each of its Subsidiaries; provided, however, that the Company
shall not be required to preserve, with respect to itself, any right or
franchise, and with respect to any of its Subsidiaries, any such existence,
right or franchise, if (a) the Board of Directors of the Company shall determine
that the preservation thereof is no longer desirable in the conduct of the
business of the Company and (b) the loss thereof is not disadvantageous in any
material respect to the Holders.

        Section 4.5 Payment of Taxes and Other Claims. The Company shall, and
shall cause each of its Subsidiaries to, pay or discharge or cause to be paid or
discharged, before the same shall become delinquent all taxes, assessments and
governmental charges (including withholding taxes and any penalties, interest
and additions to taxes) levied or imposed upon the Company or any of its
Subsidiaries or any of their respective properties and assets; provided,
however, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment or charge whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings and for which disputed amounts adequate reserves have been
established in accordance with GAAP.

        Section 4.6  Maintenance of Properties and Insurance.

        (a) Each of the Company and its Subsidiaries shall cause the properties
used or useful to the conduct of its business and the business of each of its
Subsidiaries to be maintained and kept in good condition, repair and working
order (reasonable wear and tear excepted) and supplied with all necessary

        (b) Each of the Company and its Subsidiaries shall provide, or shall
cause to be provided, for itself and each of its Subsidiaries, insurance
(including appropriate self-insurance) against loss or damage of the kinds that,
in its reasonable, good faith opinion, are adequate and appropriate for the
conduct of its business and the business of such Subsidiaries in a prudent
manner, with reputable insurers or with the government of the United States of
America or an agency or instrumentality thereof, in such amounts, with such
deductibles, and by such methods as is customary, in its reasonable, good faith
opinion, and adequate and appropriate for the conduct of its business and the

similar business. In addition, all such insurance shall be payable to the
Trustee as loss payee, as its interests may appear, under a "standard" or
"Texas" loss payee clause. Without limiting the foregoing, each of the Company
and its Subsidiaries shall (i) keep all of its physical property insured with
hazard insurance on an "all risks" basis, with broad form flood and earthquake

insurance and charge the amount thereof to the Company and its Subsidiaries. The
Company and its Subsidiaries shall furnish the Trustee with certificates of
insurance and policies evidencing compliance with the foregoing insurance
provision.

        (a) The Company shall deliver to the Trustee within 60 days after the
end of each of its fiscal quarters, or 105 days after the end of a fiscal

to determining whether the Company and its Subsidiaries have kept, observed,
performed and fulfilled its obligations (excluding those obligations addressed
by Section 11.3) under this Indenture and further stating, as to each such
Officer signing such certificate, regardless of whether the signer knows of any
failure by the Company or any Subsidiary of the Company to comply with any
conditions or covenants in this Indenture, or of the occurrence of any Default,
and, if such signer does know of such a failure to comply or Default, the
certificate shall describe such failure or Default with particularity.

attention that caused them



                                       33

described in the above clauses, the Company or the Subsidiary in question shall
have the right to determine in its sole discretion the category to which such
Debt applies and shall not be required to include the amount and type of such
Debt in more than one of such categories and may elect to apportion such item of
Debt between or among any two or more of such categories otherwise applicable,
provided, however, that any Refinancing Debt Incurred by the Company as an
extension, renewal, replacement or refunding of Debt existing on the Issue Date
and initially categorized upon Incurrence under Section 4.11(c) or Section
4.11(d) must continue to be categorized under, and apportioned in its entirety
to, Section 4.11(c) or Section 4.11(d), as the case may be, and (B) the amount
of any Debt which does not pay interest in cash or which was issued at a

        Section 4.12 Limitations on Restricting Subsidiary Dividends. The
Company shall not, and shall not permit any of its Subsidiaries to, directly or

except encumbrances and restrictions existing under this Indenture, the Extended
DIP Facility, the Post Confirmation Credit Facility or the Revolving Credit
Facility (or any refinancing of any such Debt facilities incurred in accordance
with Section 4.11(g)), and any agreement of a Person acquired by the Company or
a Subsidiary of the Company, which restrictions existed at the time of
acquisition, were not put in place in anticipation of such acquisition and are
not applicable to any Person or property, other than the Person or any property
of the Person so acquired.


        Section 4.13 Limitation on Liens. The Company shall not, and shall not
permit any of its Subsidiaries to, directly or indirectly, Incur, or suffer to
exist any Lien upon any of its respective property or assets, whether now owned

Section 4.13, if a Lien meets the criteria of more than one of the types of
Permitted Liens, the Company or the Subsidiary in question shall have the right
to determine in its sole discretion the category of Permitted Lien to which such
Lien applies, shall not be required to include such Lien in more than one of
such categories, and may elect to apportion such Lien between or among any two
or more categories otherwise applicable.

        Section 4.14  Limitation on Asset Sales.

        (a) The Company shall not, and shall not permit any of its Subsidiaries
to, consummate an Asset Sale unless (A) an amount equal to the Net Cash Proceeds
therefrom is (i) applied to a Note Redemption, (ii) used to make cash payments
in the ordinary course of business and consistent with past practices that are
not otherwise prohibited by this Indenture, provided, however, that the

below), (iii) used for Capital Expenditures in a Related Business within 180
days after the date of such Asset Sale; or (iv) with respect to an Asset Sale by
the Company or any of its Subsidiaries resulting from (x) the damage to or
destruction of assets for which insurance proceeds are paid or (y) condemnation,
eminent domain or similar type proceedings, in each case, used for Capital
Expenditures in a Related Business within 360 days after the date of such Asset
Sale; and (B) in the case of any Asset Sale or series of related Asset Sales for
total proceeds in excess of $1 million, at least 85% of the value of the
consideration for such Asset Sale consists of cash, Cash Equivalents or Exchange
Assets, or any combination thereof.

        (b) To the extent of the balance of such Net Cash Proceeds remaining
after application in accordance with Section 4.14(a), the Company shall make an
offer to the Holders to purchase Notes pursuant to and subject to the conditions
contained in this Indenture. Notwithstanding the foregoing provision of this




                                       37
<PAGE>   45

paragraph, the Company and its Subsidiaries shall not be required to apply any
Net Cash Proceeds in accordance with this Section 4.14(b) except to the extent
that the aggregate Net Cash Proceeds from all Asset Sales which are not applied
in accordance with Section 4.14(a) or with this Section 4.14(b) exceeds $5
million. Pending application of Net Cash Proceeds pursuant to this Section
4.14(b), such Net Cash Proceeds shall be invested in Permitted Investments.

        (c) In the event of an Asset Sale that requires the purchase of Notes
pursuant to Section 4.14(b), the Company shall be required to purchase Notes
tendered pursuant to an offer by the Company for the Notes (the "Repurchase
Offer") at a purchase price of 100% of their principal amount (without premium)
plus accrued but unpaid interest in accordance with the procedures (including
prorating in the event of oversubscription) set forth in Section 4.14(d). The
Company shall not be required to make a Repurchase Offer to purchase Notes
pursuant to this Section 4.14 if the Net Cash Proceeds available therefor is
less than $5 million (which lesser amount shall be carried forward for purposes
of determining whether such an Offer is required with respect to the Net Cash
Proceeds from any subsequent Asset Sale).

        (d) (1) Promptly, and in any event within 20 days after the Company
becomes obligated to make a Repurchase Offer, the Company shall be obligated to
deliver to the Trustee and send, by first-class mail to each Holder, a written
notice stating that the Holder may elect to have his Notes purchased by the
Company either in whole or in part (subject to prorating as hereinafter
described in the event the Offer is oversubscribed) in integral multiples of
$1,000 of principal amount, at the applicable purchase price. The notice shall
specify a purchase date not less than 30 days nor more than 60 days after the
date of such notice (the "Repurchase Date") and shall contain such information
concerning the business of the Company which the Company in good faith believes
will enable such Holders to make an informed decision (which at a minimum will
include (i) the most recently filed Annual Report on Form 10-K (including
audited consolidated financial statements) of the Company, the most recent
subsequently filed Quarterly Report on Form 10-Q of the Company and any Current
Report on Form 8-K of the Company filed subsequent to such Quarterly Report,
other than Current Reports describing Asset Sales otherwise described in the
offering materials (or corresponding successor reports), (ii) a description of
material developments in the Company's. business subsequent to the date of the
latest of such Reports, (iii) if material, appropriate pro forma financial
information, and (iv) all instructions and materials necessary to tender Notes
pursuant to the Repurchase Offer, together with the information contained in
clause (3) of this Section 4.14(d).

               (2) Not later than the date upon which written notice of a
Repurchase Offer is delivered to the Trustee as provided below, the Company
shall deliver to the Trustee an Officers' Certificate as to (i) the amount of
the Repurchase Offer (the "Repurchase Offer Amount") , (ii) the allocation of
the Net Cash Proceeds from the Asset Sales pursuant to which such Offer is being
made, and (iii) the compliance of such allocation with the provisions of Section
4.06(b). On such date, the Company shall also irrevocably deposit with the
Trustee or with a paying agent (or, if the Company is acting as its own paying
agent, segregate and hold in trust) in cash or Cash Equivalents, maturing on the
last day prior to the Repurchase Date or on the Repurchase Date if funds are
immediately available by opening of business, an amount equal to the Repurchase
Offer Amount to be held for payment in accordance with the provisions of this
Section 4.14. Upon the expiration of the period for which the Repurchase Offer
remains open (the "Repurchase Offer Period"), the Company shall deliver to the
Trustee for cancellation the Notes or portions thereof which have been properly
tendered to and are to be accepted by the Company. The Trustee shall, on the
Repurchase Date, mail or deliver payment to each tendering Holder in the amount
of the purchase price. In the event that the aggregate purchase price of the
Notes delivered by the Company to the Trustee is less than the Repurchase Offer
Amount applicable to the Notes so delivered, the Trustee shall deliver the
excess to the Company immediately after the expiration of the Repurchase Offer
Period for application in accordance with this Section 4.14, including, during
the period ending 180 days after such delivery, the provisions of Section
4.14(a).

               (3) Holders electing to have a Note purchased shall be required
to surrender the Note, with an appropriate form duly completed, to the Company
at the address specified in the notice at least three Business Days prior to the
Repurchase Date. Holders shall be entitled to withdraw their election if the
Trustee or the Company receives not later than one Business Day prior to the
Repurchase Date, a telex, facsimile transmission or letter setting forth the
name of the Holder, the principal amount of the Note which was delivered for
purchase by the Holder and a statement that such Holder is withdrawing his
election to have such Note purchased. If at the expiration of the Offer Period
the aggregate principal amount of Notes surrendered by Holders exceeds the
Repurchase Offer Amount, the Company shall select the Notes to be purchased on a
pro rata basis (with such adjustments as may be deemed appropriate by the
Company so that only Notes in denominations of $1,000, or integral multiples
thereof, shall be purchased). Each Holder whose Notes are purchased only in part
shall be issued new Notes equal in principal amount to the unpurchased portion
of the Notes surrendered by such Holder.

               (4) At the time the Company delivers Notes to the Trustee which
are to be accepted for purchase pursuant to this Section 4.14, the Company shall
also deliver to the Trustee an Officers' Certificate stating that such Notes are
to be accepted by the Company pursuant to and in accordance with the terms of
this Section 4.14. A Note shall be deemed to have been accepted for purchase at
the time the Trustee, directly or through an agent, mails or delivers payment
therefor to the surrendering Holder.

        (e) The Company shall comply, to the extent applicable, with the
requirements of Section 14 (e) of the Exchange Act and any other securities laws
or regulations in connection with the purchase of Notes pursuant to this Section
4.14. To the extent that the provisions of any securities laws or regulations
conflict with provisions of this Section 4.14, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under this Section 4.14 by virtue of such compliance.

        (f) Notwithstanding the foregoing limitations on Asset Sales and
restrictions on and requirements for the use of Net Cash Proceeds therefrom, the
Company and its Subsidiaries, as the case may be, may at any time and from time
to time effect any of the following transactions, and the Net Cash Proceeds, if
any, realized from any of the following transactions shall not be subject to the
application requirements of Section 4.14(a) or Section 4.14(b):

               (i) the Company or any Subsidiary of the Company may convey,
        sell, lease, transfer, or otherwise dispose of any or all of its assets
        (upon voluntary liquidation or otherwise) to the Company or to a wholly
        owned Subsidiary of the Company;

               (ii) the Company and its Subsidiaries may engage in Asset Sales
        not otherwise permitted in clauses (i) or (iii) through (vi) of this
        Section 4.14(f), provided, however, that the aggregate proceeds from all
        such Asset Sales and the fair market value of all assets sold pursuant
        to this clause (ii) does not exceed $1 million in any twelve-month
        period;

               (iii) the Company and its Subsidiaries may engage in Asset Sales
        incident to and resulting from a transaction expressly permitted under
        Section 5.1;

               (iv) the Company and its Subsidiaries may sell, assign, lease,
        license, transfer, abandon or otherwise dispose of (a) damaged, worn
        out, unserviceable or other obsolete property in the ordinary course of
        business, or (b) other property no longer necessary for the proper
        conduct of their business;




                                       39
<PAGE>   47

               (v) the Company and its Subsidiaries may engage in Asset Sales
        (a) in connection with the settlement of litigation or the payment of
        judgments, or (b) the Net Cash Proceeds of which are used in connection
        with the settlement of litigation or for the payment of judgments;
        provided, however, that the aggregate value of assets transferred
        pursuant to clauses (a) and (b) preceding from and after the Issue Date
        does not exceed $10 million;

               (vi) the Company and its Subsidiaries may convey, sell, transfer

        ordinary course of business; and

               (vii) the Company and its Subsidiaries may convey, sell, transfer
        or otherwise dispose of Drilling Production Payments and interests

        disposition shall be used for Capital Expenditures or to make a
        Repurchase Offer.

        (g) For the purpose of determining compliance with this Section 4.14
with respect to the application or use of the Net Cash Proceeds of any Asset
Sale consummated by the Company or any Subsidiary of the Company, if such Net
Cash Proceeds would be eligible for application or use under or pursuant to more
than one of the categories of application or use permitted under Section 4.14(a)
or Section 4.14(f), without, for purposes of determining such eligibility only,
giving effect to any specific limitation on the amount or the aggregate amount
of Net Cash Proceeds that may be applied or used under any otherwise eligible
category of application or use in effect at the time such application is to be
effected, the Person in question consummating such Asset Sale shall have the
right to determine in its sole discretion the eligible category or categories of
application or use pursuant to which all or any portion of such Net Cash
Proceeds shall be applied or used, and may, at its option and in its sole
discretion, elect either (i) to effect the application or use of the full amount
of such Net Cash Proceeds pursuant to any one of such eligible categories of
application or use permitted under Section 4.14(a) or Section 4.14(f), subject,
however, to any limitation on the amount or the aggregate amount that may be
applied or used under such eligible category of application or use in effect at
the time such application or use is effected, or (ii) to effect the application
or use of such Net Cash Proceeds by apportioning the full amount of such Net
Cash Proceeds to be applied or used between or among any two or more of such
eligible categories of application or use permitted under Section 4.14(a) or
Section 4.14(f) in such amounts and order of application or use as the Person in
question consummating such Asset Sale may determine in its sole discretion,
subject, however, as to each portion of such Net Cash Proceeds apportioned for
application or use under any one of such eligible categories of application or
use, to any limitation on the amount or the aggregate amount of Net Cash
Proceeds that may be applied or used under such eligible category of application
or use in effect at the time such application or use is effected.

        Section 4.15 Waiver of Stay, Extension or Usury Laws. The Company and
each Guarantor covenants (to the extent that it may lawfully do so) that it will
not at any time insist upon, 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 which would prohibit or forgive the Company or any Guarantor from paying all
or any portion of the principal of or interest on the Notes as contemplated
herein, wherever enacted, now or at any time hereafter in force, or which 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.

        It is the intention of the parties hereto to comply strictly with
applicable usury laws; accordingly, notwithstanding any provision to the
contrary in this Indenture or in any of the documents securing the payment of
the Notes or otherwise relating thereto, in no event shall this Indenture or
such documents require


                                       40

or permit the payment, charging, taking, reserving, or receiving of any sums
constituting interest under applicable laws which exceed the maximum amount
permitted by such laws. If any such excess interest is contracted for, charged,
taken, reserved, or received in connection with the Notes or in any of the
documents securing the payment thereof or otherwise relating thereto, or in any
communication by the Holders or any other Person to the Company or any other
Person, or in the event all or part of the principal or interest on the Notes
shall be prepaid or accelerated, so that under any of such circumstances or
under any other circumstance whatsoever the amount of interest contracted for,
charged, taken, reserved, or received on the amount of principal actually
outstanding from time to time under the Notes shall exceed the maximum amount of
interest permitted by applicable usury laws, then in any such event it is agreed
as follows: (i) the provisions of this paragraph shall govern and control, (ii)
any such excess shall be deemed an accidental and bona fide error and canceled
automatically to the extent of such excess, and shall not be collected or
collectible, (iii) any such excess which is or has been paid or received
notwithstanding this paragraph shall be credited against the then unpaid
principal balance on the Notes or refunded to the Company, at the Holders'
option, and (iv) the effective rate of interest shall be automatically reduced
to the maximum lawful rate allowed under applicable laws as construed by courts
having jurisdiction hereof or thereof. Without limiting the foregoing, all
calculations of the rate of interest contracted for, charged, taken, reserved,
or received in connection herewith which are made for the purpose of determining
whether such rate exceeds the maximum lawful rate shall be made to the extent
permitted by applicable laws by amortizing, prorating, allocating and spreading
during the period of the full term of the Notes, including all prior and
subsequent renewals and extensions, all interest at any time contracted for,
charged, taken, reserved, or received. The terms of this paragraph shall be
deemed to be incorporated in every document, security instrument, and
communication relating to this Indenture and the Notes.

        Section 4.16 Guarantee by Subsidiaries. If the Company or any of its
Subsidiaries shall make Investments in an aggregate amount, or otherwise
transfer (including by capital contribution) or cause to be transferred, in a
manner otherwise permitted pursuant to this Indenture, any assets (tangible or
intangible), businesses, divisions, real property, or equipment having a book
value as shown in the Company's most recent consolidated balance sheet or the
notes thereto (or if greater, a fair market value at the time of transfer) in
excess of $1 million in or to any Subsidiary of the Company, that is not a
Guarantor, the Company shall cause such transferee Subsidiary (a) to guarantee
payment of the Notes by executing a Guarantee, (b) to execute the appropriate
Security Documents, in substantially the form of the relevant Security Documents
executed and delivered on or about the Issue Date, necessary to grant a security
interest in all of the assets of such Subsidiary (other than Inventory and
Receivables, which shall be excepted from the Lien thereof) to secure such
Guarantee, and (c) to execute a supplemental indenture in which such Subsidiary
agrees to become and be a Guarantor and to be bound by the terms of this
Indenture. If the Company or any of its Subsidiaries shall subsequently sell or
otherwise transfer all of the Capital Stock of such Subsidiary held by the
Company or any of its Subsidiaries, the Guarantee (and the related Security
Documents) required hereby shall be withdrawn or canceled.

        The liability of each Guarantor under its Guarantee (and the related
Security Documents) will be limited to the amount of its Adjusted Net Assets.
Each Guarantor that makes a payment under or by reason of its Guarantee of the
Notes shall be entitled to assert a claim for reimbursement from each other
Guarantor of the Notes in an amount not to exceed the product of (x) the other
Guarantor's Adjusted Net Assets multiplied by (y) a fraction, the numerator of
which is the other Guarantor's Adjusted Net Assets and the denominator of which
is the sum of the Adjusted Net Assets of all Guarantors of the Notes.

        Section 4.17 Limitations on Line of Business. The Company shall not,
and shall not permit any Subsidiary of the Company to, directly or indirectly
engage to any substantial extent in any line or lines of business activity other
than a Related Business or such other business activities as are reasonably
related or incidental thereto.

Company, or such of its Subsidiaries, as the case may be, all of such Nominee's
right, title and interest in and to such Nominee Property.

indirectly, sell, lease, assign, transfer or convey all or substantially all of
its assets (computed on a consolidated basis), to another Person or group of
Persons acting in concert, whether in a single transaction or through a series
of related transactions, unless:

               (1) either (a) the Company or such Subsidiary, as the case may
        be, shall be the continuing Person, or (b) the Person (if other than the
        Company) formed by such consolidation or into which the Company or such
        Subsidiary, as the case may be, is merged or to which all or
        substantially all of the properties and assets of the Company or such
        Subsidiary, as the case may be, are transferred as an entirety or

        validly existing under the laws of the United States, any State thereof
        or the District of Columbia, and shall expressly assume, by an indenture
        supplemental hereto and any supplements to any Security Documents as the

        executed and delivered to the Trustee on or prior to the consummation of
        such transaction, in form satisfactory to the Trustee, all the
        obligations of the Company or such Subsidiary, as the case may be, under
        the Notes, the Security Documents, and this Indenture;

               (2) No Default or Event of Default shall exist or shall occur
        immediately after giving effect to such transaction;

               (3) immediately after giving effect to such transaction, on a pro
        forma basis, (x) the Net Worth of the Surviving Person is at least equal
        to the Net Worth of such predecessor or transferring entity immediately
        prior to such transaction, and (y) the Surviving Person immediately
        after giving effect on a pro forma basis to the Consolidated Fixed

        greater than 2.5 to 1, and (B) the Surviving Person's Adjusted
        Consolidated Tangible Assets are equal to or greater than 150% of the
        total consolidated principal amount or accreted value, as the case may

               (4) the Company has delivered to the Trustee an Officers'
        Certificate and an Opinion of Counsel, each stating that such
        consolidation, merger, assignment, or transfer and such supplemental
        indenture comply with this Article V and that all conditions precedent
        herein provided relating to such transaction have been satisfied; and

               (5) at the time of or within 120 days after the occurrence of the
        event specified above, the Notes have not been or are not downgraded by
        S&P, Moody's, or any successor rating agencies to either entity to a

        specified above is first publicly announced.

For purposes of this Section 5.1(a), the Consolidated Fixed Charge Coverage
Ratio shall be determined on a pro forma consolidated basis (giving effect to
such transaction) for the four fiscal quarters immediately preceding such
transaction.

        (b) For purposes of Section 5.1(a), the sale, lease, conveyance,
assignment, transfer, or other disposition of all or substantially all of the

the Company (or a wholly owned Subsidiary of the Company) at any time, provided,
however, that the Company shall have delivered to the Trustee an Officers'
Certificate stating that such Subsidiary has a Net Worth greater than zero and
such merger does not result in a Default or an Event of Default hereunder.

        Section 5.2 Successor Corporation Substituted. Upon any consolidation or
merger, or any transfer of assets in accordance with Section 5.1, the Surviving

                                   ARTICLE VI

                         EVENTS OF DEFAULT AND REMEDIES


        Section 6.1 Events of Default. "Event of Default," wherever used
herein, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be caused voluntarily or involuntarily or
effected, without limitation, 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 any interest upon any Note as and when the
same becomes due and payable, and the continuance of such default for a period
of thirty (30) days;

        (b) default in the payment of all or any part of the principal of (or
premium, if any, applicable to), the Notes when and as the same becomes due and
payable at maturity, redemption, by acceleration, or otherwise, including any
payment due by reason of the occurrence of a Change of Control;

        (c) default in the observance or performance of, or breach of, any
covenant, agreement or warranty of the Company or any of its Subsidiaries
contained in the Notes or this Indenture or any of the Security Documents, and
continuance of such default or breach for the period and after the notice, if
any, specified below;

        (d) a default which extends beyond any stated period of grace applicable
thereto, including any extension thereof, under any mortgage, indenture or
instrument under which there is outstanding any Debt of the Company or any of
its Subsidiaries with an aggregate principal amount in excess of $5 million if
by reason of such default the principal of such Debt and all accrued and unpaid
interest thereon have been declared due and payable, or failure to pay such Debt
at its stated maturity, provided, however, that a waiver by all of the lenders
of such debt of such default shall constitute a waiver hereunder for the same
period;

        (e) a decree, judgment, or order by a court of competent jurisdiction
shall have been entered adjudging the Company or any of its Subsidiaries as
bankrupt or insolvent, or ordering relief against the Company or any of its
Subsidiaries in response to the commencement of an involuntary bankruptcy case,
or approving as properly filed a petition seeking reorganization or liquidation
of the Company or any of its Subsidiaries under any bankruptcy or similar law,
and such decree or order shall have continued undischarged and unstayed for a
period of 60 days; or a decree or order of a court of competent jurisdiction
over the appointment of a receiver, liquidator, trustee, or assignee in
bankruptcy or insolvency of the Company, any of its Subsidiaries, or of the
property of any such Person, or for the winding up or liquidation of the affairs
of any such Person, shall have been entered, and such decree, judgment, or order
shall have remained in force undischarged and unstayed for a period of 60 days;

        (f) the Company or any of its Subsidiaries shall institute voluntary
bankruptcy proceedings, or shall consent to the filing of a bankruptcy
proceeding against it, or shall file a petition or answer or consent seeking
reorganization or liquidation under any bankruptcy or similar law or similar
statute, or shall consent to the filing of any such petition, or shall consent
to the appointment of a Custodian, receiver, liquidator, trustee, or assignee in
bankruptcy or insolvency of it or any of its assets or property, or shall make a
general assignment for the benefit of creditors, or shall admit in writing its
inability to pay its debts generally as they become due, or shall, within the
meaning of any Bankruptcy Law, become insolvent, fail generally to pay its debts
as they become due, or take any corporate action in furtherance of or to
facilitate, conditionally or otherwise, any of the foregoing;





                                       44
<PAGE>   52


        (g) final judgments not covered by insurance for the payment of money,
or the issuance of any warrant of attachment against any portion of the property
or assets of the Company or any Subsidiary, which, in the aggregate, equal or
exceed $5 million at any one time shall, be entered against the Company or any
of its Subsidiaries by a court of competent jurisdiction and not be stayed,
bonded or discharged for a period (during which execution shall not be
effectively stayed) of 60 days (or, in the case of any such final judgment which
provides for payment over time, which shall so remain unstayed, unbonded or
undischarged beyond any applicable payment date provided therein); or

        (h) except as caused by a release effected pursuant to and in accordance
with this Indenture, any of the Security Documents shall for any reason cease to
be in full force and effect other than pursuant to the terms thereof (except
where no material adverse effect to the Holders would result), or shall cease to
give the Trustee, for the ratable benefit of the Holders the Liens, rights,
powers and privileges purported to be created thereby including but not limited
to, a perfected security interest in, and Lien on, the Collateral in accordance
with the terms thereof, except where the failure to have such Liens, rights,
powers and privileges shall not have a material adverse effect on the Holders.

        If a Default occurs and is continuing and if it is known to the Trustee,
the Trustee must, within 90 days after the occurrence of such default, give to
the Holders notice of such Default; provided, however, that, except in the case
of Default in payment of principal of, premium, if any, or interest on the
Notes, the Trustee will be protected in withholding such notice if it in good
faith determines that the withholding of such notice is in the interest of the
Holders.

        A Default under clause (c) above (other than in the case of any Defaults
under Sections 4.3, 4.11, 4.13, 4.14, 4.16 or 5.1, which Defaults shall become
Events of Default without the notice specified in this paragraph or in Section
4.7(c) and upon the passage of 10 days) is not an Event of Default until the
Trustee notifies the Company, or the Holders of at least 25% in principal amount
of the outstanding Notes notify the Company and the Trustee of the Default, and
the Company does not cure the Default within 30 days after receipt of the
notice. The notice must specify the Default, demand that it be remedied and
state that the notice is a "Notice of Default." Such notice shall be given by
the Trustee if so requested by the Holders of at least 25% in principal amount
of the Notes then outstanding.

        In the case of any Event of Default pursuant to the provisions of this
Section 6.1 occurring by reason of any willful action (or inaction) taken (or
not taken) by or on behalf of the Company or any Subsidiary with the intention
of avoiding the period of time the Notes are not optionally redeemable or the
payment of the premium which the Company would have to pay if the Company then
had elected to redeem the Notes pursuant to Paragraph 5 of the Notes, an
equivalent premium (or, in the case of an Event of Default prior to the time
optional redemptions are permitted, to the extent permitted by law, a premium
equal to the stated interest rate of the Notes multiplied by the quotient of (i)
the number of full years left to maturity plus one, divided by (ii) five) shall
also become and be immediately due and payable to the extent permitted by law,
anything in this Indenture or in the Notes to the contrary notwithstanding.



        Section 6.2 Acceleration of Maturity Date; Rescission and Annulment. If
an Event of Default (other than an Event of Default specified in Section 6.1(e)
or Section 6.1(f) relating to the Company or any of its Subsidiaries) occurs and
is continuing, then, and in every such case, unless the principal of all of the
Notes shall have already become due and payable, either the Trustee or the
Holders of not less than 25% in aggregate principal amount of then outstanding
Notes, by a notice in writing to the Company (and to the Trustee if given by
Holders) (an "Acceleration Notice"), may declare all of the principal of the
Notes, determined as set forth below, including in each case accrued interest
thereon, to be due and payable immediately. If an Event of Default specified in
Section 6.1(e) or (f) relating to the Company or any of its Subsidiaries



                                       45
<PAGE>   53


occurs, all principal and accrued interest on the Notes shall be immediately due
and payable on all outstanding Notes without any declaration or other act on the
part of the Trustee or the Holders.

        At any time after such a declaration of acceleration being made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter provided in this Article VI, the Holders of 75% in
aggregate principal amount of then outstanding Notes, by written notice to the
Company and the Trustee, may waive, on behalf of all Holders, any such
declaration of acceleration if:

        (a) the Company has paid or deposited with the Trustee a sum sufficient
to pay:

               (1)  all accrued but unpaid interest on all Notes,

               (2) the principal of (and premium, if any, applicable to) any
        Notes which would become due otherwise than by such declaration of
        acceleration, and accrued but unpaid interest thereon at the rate borne
        by the Notes,

               (3) to the extent that payment of such interest is lawful,
        interest upon overdue interest at the rate borne by the Notes, and

               (4) all sums paid or advanced by the Trustee hereunder and the
        compensation, expenses, disbursements and advances of the Trustee, its
        agents and counsel; and

        (b) all Events of Default, other than the non-payment of the principal
of, premium, if any, and interest on Notes which have become due solely by such
declaration of acceleration, have been cured or waived as provided in Section
6.12.

        Notwithstanding the previous sentence of this Section 6.2, no waiver
shall be effective for any Event of Default or event which with notice or lapse
of time or both would be an Event of Default with respect to any covenant or
provision which cannot be modified or amended without the consent of (x) 75% in
aggregate principal amount of the Notes, or (y) the affected Holder of each of
the outstanding Notes, unless (x) 75% in aggregate principal amount of the
Notes, or (y) all such affected Holders, respectively, agree, in writing, to
waive such Event of Default or event. No such waiver shall cure or waive any
subsequent default or impair any right consequent thereon.


        Section 6.3 Collection of Indebtedness and Suits for Enforcement by
Trustee. The Company covenants that if an Event of Default in payment of
principal, premium or interest specified in clause (a) or clause (b) of Section
6.1 occurs and is continuing, the Company shall, upon demand of the Trustee, pay
to it, for the benefit of the Holders of such Notes, the whole amount then due
and payable on such Notes for principal, premium (if any) and interest, and, to
the extent that payment of such interest shall be legally enforceable, interest
on any overdue principal (and premium, if any) and on any overdue interest, at
the rate borne by the Notes, and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including
compensation to, and expenses, disbursements and advances of the Trustee, its
agents and counsel.

        If the Company fails to pay such amounts within 10 days of such demand,
the Trustee, in its own name and as trustee of an express trust in favor of the
Holders, may institute a judicial proceeding for the collection of the sums so
due and unpaid, may prosecute such proceeding to judgment or final decree and
may enforce the same against the Company or any other obligor upon the Notes and
collect the moneys adjudged or decreed to be payable in the manner provided by
law out of the property of the Company or any other obligor upon the Notes,
wherever situated.



                                       46
<PAGE>   54

        If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effective to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

        The Trustee shall also be authorized to take whatever additional action
at law or in equity may appear to be necessary or desirable to collect the
monies necessary to pay the principal, premium (if any) and interest on the
Notes.

        Section 6.4 Trustee May File Proofs of Claim. In case of the pendency
of any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Company or any other obligor upon the Notes or the property of the Company
or of such other obligor or their creditors, the Trustee (irrespective of
whether the principal of the Notes shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand on the Company or any obligor for the payment of
overdue principal or interest) shall be entitled and empowered, by intervention
in such proceeding or otherwise to take any and all actions under the TIA,
including:

        (a) to file and prove a claim for the whole amount of principal (and
premium, if any) and interest owing and unpaid in respect of the Notes 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 the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agent and
counsel) and of the Holders allowed in such judicial proceeding, and

        (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same;

and any debtor-in-possession or Custodian or other similar official in any such
judicial proceeding is hereby authorized by each Holder to make such payments to
the Trustee and, in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due it
for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.7.

        Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment, or composition affecting the Notes or
the rights of any Holder thereof or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.

        Section 6.5 Trustee May Enforce Claims Without Possession of Notes. All
rights of action and claims under this Indenture or the Notes may be prosecuted
and enforced by the Trustee without the possession of any of the Notes or the
production thereof in any proceeding relating thereto, and any such proceeding
instituted by the Trustee shall be brought in its own name as trustee of an
express trust in favor of the Holders, and any recovery of judgment shall, after
provision for the payment of compensation to, and expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Notes in respect of which such judgment has been recovered.

        Section 6.6 Priorities. Subject to the provisions of the Intercreditor
Agreements, any money collected by the Trustee pursuant to this Article VI shall
be applied in the following order, at the date or dates



                                       47
<PAGE>   55

fixed by the Trustee and, in case of the distribution of such money on account
of principal, premium (if any) or interest, upon presentation of the Notes and
the notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

        FIRST: To the Trustee in payment of all amounts due pursuant to Section
7.7;

        SECOND: To the Holders in payment of the amounts then due and unpaid for
principal of, premium (if any) and interest on, the Notes in respect of which or
for the benefit of which such money has been collected, ratably, without
preference or priority of any kind, according to the amounts due and payable on
such Notes for principal, premium (if any) and interest respectively; and

        THIRD:  To whomsoever may be lawfully entitled thereto, the remainder,
if any.

        Section 6.7 Limitation on Suits. No Holder of any Note shall have any
right to order or direct the Trustee to institute any proceeding, judicial or
otherwise, with respect to this Indenture, or for the appointment of a receiver
or trustee, or for any other remedy hereunder, unless:

        (a) such Holder has previously given written notice to the Trustee of a
continuing Event of Default;

        (b) the Holders of not less than 25% in principal amount of then
outstanding Notes shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default in its own name as Trustee
hereunder;

        (c) such Holder or Holders have offered to the Trustee reasonable
security or indemnity against the costs, expenses and liabilities to be incurred
or reasonably probable to be incurred in compliance with such request;

        (d) the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity has failed to institute any such proceeding; and

        (e) no direction inconsistent with such written request has been given
to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the outstanding Notes;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

        Section 6.8 Unconditional Right of Holders to Receive Principal,
Premium and Interest. Notwithstanding any other provision of this Indenture, the
Holder of any Note shall have the right, which is absolute and unconditional, to
receive payment of the principal of, and premium (if any) and interest on, such
Note on the Interest Payment Date or Maturity Dates of such payments as
expressed in such Note and to institute suit for the enforcement of any such
payment after such respective dates, and such rights shall not be impaired
without the consent of such Holder.

        Section 6.9 Rights and Remedies Cumulative. Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Notes in Section 2.7, 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



                                       48
<PAGE>   56

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.

        Section 6.10 Delay or Omission Not Waiver. No delay or omission by the
Trustee or by any Holder of any Note to exercise any right or remedy arising
upon any Event of Default shall impair the exercise of any such right or remedy
or constitute a waiver of any such Event of Default. Every right and remedy
given by this Article VI or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders, as the case may be.


        Section 6.11 Control by Holders. The Holder or Holders of 662/3% in
aggregate principal amount of then outstanding Notes 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 upon the
Trustee, provided, however, that:

        (a) such direction shall not be in conflict with any rule of law or with
this Indenture,

        (b) the Trustee shall not determine that the action so directed would be
unjustly prejudicial to the Holders not taking part in such direction or that
such action may involve the Trustee in personal liability, and

        (c) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction.



        Section 6.12 Waiver of Past Default. Subject to Section 6.8, the Holder
or Holders of not less than 66 2/3% in aggregate principal amount of the
outstanding Notes may, on behalf of all Holders, prior to the declaration of the
maturity of the Notes, waive any past default hereunder and its consequences,
except a default:

        (a) in the payment of the principal of, premium, if any, or interest on,
any Note as specified in clauses (a) and (b) of Section 6.1,

        (b) which arises because of a violation of the provisions of Section
9.2, or

        (c) in respect of a covenant or provision hereof which, under Article
IX, cannot be modified or amended without the consent of the Holder of each
outstanding Note affected or 75% in aggregate principal amount of the Notes at
the time outstanding, as the case may be; provided, however, that such a default
may be waived by the consent of Holders of each outstanding Note affected or 75%
in aggregate principal amount of the Notes outstanding, as the case may be.

        Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair the exercise of any right arising therefrom.


        Section 6.13 Undertaking for Costs. All parties to this Indenture
agree, and each Holder of any Note by his 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 to be taken 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 merits and good faith of the
claims or defenses made by such party litigant; but the provisions of this
Section shall



                                       49
<PAGE>   57

not apply to any suit instituted by the Company, to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in aggregate principal amount of the outstanding
Notes, or to any suit instituted by any Holder for enforcement of the payment of
principal of, or premium (if any) or interest on, any Note on or after the
respective Maturity Date expressed in such Note (including, in the case of
redemption, on or after the Redemption Date).

        Section 6.14 Restoration of Rights and Remedies. If the Trustee or any
Holder has instituted any proceeding to enforce any right or remedy under this
Indenture and such proceeding has been discontinued or abandoned for any reason,
or has been determined adversely to the Trustee or to such Holder, then and in
every case, subject to any determination in such proceeding, the Company, the
Trustee and the Holders shall be restored severally and respectively to their
former positions hereunder and thereafter all rights and remedies of the Trustee
and the Holders shall continue as though no such proceeding had been instituted.


                                   ARTICLE VII

                                     TRUSTEE

        The Trustee hereby accepts the trust imposed upon it by this Indenture
and covenants and agrees to perform the same, as herein expressed.

        Section 7.1  Duties of Trustee.

        (a) If a Default or an Event of Default has occurred and is continuing,
the Trustee shall exercise 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 person would exercise or use under the circumstances in the conduct of
his own affairs.

        (b)  Except during the continuance of a Default or an Event of Default:

               (1) The Trustee need perform only those duties as are
        specifically set forth in this Indenture and no others, and no covenants
        or obligations shall be implied in or read into this Indenture which are
        adverse to the Trustee.

               (2) In the absence of bad faith on its part, the Trustee may
        conclusively rely, as to the truth of the statements and the correctness
        of the opinions expressed therein, upon certificates or opinions
        furnished to the Trustee and conforming to the requirements of this
        Indenture. However, the Trustee shall examine the certificates and
        opinions to determine whether or not they conform to the requirements of
        this Indenture.

        (c) The Trustee may not be relieved from liability for its own negligent
action, its own negligent failure to act, or its own willful misconduct, except
that:

               (1) This paragraph does not limit the effect of paragraph (b) of
        this Section 7.1.

               (2) The Trustee shall not be liable for any error of judgment
        made in good faith by a Trust Officer, unless it is proved that the
        Trustee was negligent in ascertaining the pertinent facts.

               (3) The Trustee shall not be liable with respect to any action it
        takes or omits to take in good faith in accordance with a direction
        received by it pursuant to Section 6.2 or Section 6.11.




                                       50
<PAGE>   58

        (d) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or to take or omit to take any action
under this Indenture or at the request, order or direction of the Holders or in
the exercise of any of its rights or powers if it shall have reasonable grounds
for believing that repayment of such funds or adequate indemnity against such
risk or liability is not reasonably assured to it.

        (e) Every provision of this Indenture that in any way relates to the
Trustee is subject to subsections (a), (b), (c), (d), and (f) of this Section
7.1.

        (f) The Trustee shall not be liable for interest on any assets received
by it except as the Trustee may agree in writing with the Company. Assets held
in trust by the Trustee need not be segregated from other assets except to the
extent required by law.

        (g) The Trustee shall execute and deliver the Intercreditor Agreements
and any Subordination Agreements as provided in Section 11.2.

        Section 7.2  Rights of Trustee.  Subject to Section 7.1:

        (a) The Trustee may rely and shall be fully protected in acting or
refraining from acting on any document believed by it to be genuine and to have
been signed or presented by the proper Person. The Trustee need not investigate
any fact or matter stated in the document.

        (b) Before the Trustee acts or refrains from acting, it may consult with
counsel and may require an Officers' Certificate or an Opinion of Counsel, which
shall conform to Sections 14.4 and 14.5. The Trustee shall not be liable for any
action it takes or omits to take in good faith in reliance on such certificate
or opinion.

        (c) The Trustee may act through its attorneys and agents and shall not
be responsible for the misconduct or negligence of any agent appointed with due
care.

        (d) The Trustee shall not be liable for any action it takes or omits to
take in good faith which it believes to be authorized or within its rights or
powers.

        (e) The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, notice, request, direction, consent, order, bond, debenture, or other
paper or document, but the Trustee, in its discretion, may make such further
inquiry or investigation into such facts or matters as it may see fit.

        (f) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request, order or
direction of any of the Holders, pursuant to the provisions of this Indenture,
unless such Holders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which may be incurred
therein or thereby.

        (g) Whenever by the terms of this Indenture, the Trustee shall be
required to transmit notices or reports to any or all Holders, the Trustee shall
be entitled to rely on the information provided by the Registrar as to the names
and addresses of the Holders as being correct. If the Registrar is other than
the Trustee, the Trustee shall not be responsible for the accuracy of such
information.

        Section 7.3 Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Notes and
may otherwise deal with the Company, its Subsidiaries, or their



                                       51
<PAGE>   59

respective Affiliates with the same rights it would have if it were not Trustee.
Any Agent may do the same with like rights. However, the Trustee must comply
with Sections 7.10 and 7.11.

        Section 7.4 Trustee's Disclaimer. The Trustee makes no representation
as to the validity or adequacy of this Indenture or the Notes and it shall not
be accountable for the Company's use of the proceeds from the Notes, and it
shall not be responsible for (i) the use or application of any funds received by
a Paying Agent other than the Trustee, (ii) any statement in the Notes, other
than the Trustee's certificate of authentication, or (iii) the sufficiency of
the collateral for the Notes.

        The Trustee shall not be bound to ascertain or inquire as to the
performance or observance of any covenants, conditions or agreements on the part
of the Company hereunder or in any Security Documents, except as specifically
set forth herein or therein.

        Section 7.5 Notice of Default. If a Default or an Event of Default
occurs and is continuing and if it is known to the Trustee pursuant to Section
4.7(c), the Trustee shall mail to each Noteholder notice of the uncured Default
or Event of Default within 90 days after such Default or Event of Default
occurs. Except in the case of a Default or an Event of Default in payment of
principal (or premium, if any,) of, or interest on, any Note (including all
payments due on any Maturity Date), the Trustee may withhold the notice if and
so long as the board of directors, the executive committee or a trust committee
of directors and/or responsible officers of the Trustee in good faith determines
that withholding the notice is in the interest of the Holders.

        Section 7.6 Reports by Trustee to Holders. Within 60 days after each
May 15 beginning with the May 15 following the date of this Indenture, the
Trustee shall, if required, mail to each Noteholder a brief report dated as of
such May 15 that complies with TIA ss. 313(a). The Trustee also shall comply
with TIA ss.ss. 313(b) and 313(c).

        A copy of each report at the time of its mailing to Noteholders shall be
mailed to the Company and filed with the SEC and each stock exchange, if any, on
which the Notes are listed.

        Section 7.7 Compensation and Indemnity. The Company shall pay to the
Trustee from time to time compensation for its services (in whatever capacity
rendered) in accordance with the Trustee's fee schedule, as may be amended from
time to time. The Trustee's compensation shall not be limited by any law on
compensation of a trustee of an express trust. The Company shall reimburse the
Trustee upon request for all reasonable disbursements, expenses and advances
incurred or made by it. Such expenses shall include the reasonable compensation,
disbursements and expenses of the Trustee's agents, accountants, experts and
counsel.

        The Company shall indemnify the Trustee (in its capacity as Trustee) and
each of its officers, directors, attorneys-in-fact and agents for, and hold it
harmless against, any claim, demand, expense (including but not limited to,
compensation, disbursements and expenses of the Trustees' agents and counsel),
loss or liability incurred by it without negligence or bad faith on its part,
arising out of or in connection with the administration of this trust and its
rights or duties hereunder including the reasonable costs and expenses of
defending itself against any claim or liability in connection with the exercise
or performance of any of its powers or duties hereunder. The Trustee shall
notify the Company promptly of any claim asserted against the Trustee for which
it may seek indemnity. The Company shall defend the claim and the Trustee shall
provide reasonable cooperation at the Company's expense in the defense. The
Trustee may have separate counsel and the Company shall pay the reasonable fees
and expenses of such counsel; provided, however, that the Company will not be
required to pay such fees and expenses if it assumes the Trustee's defense and
there is no conflict of interest as reasonably determined by the Trustee between
the Company and the Trustee in connection with such defense. The Company need
not pay for any settlement made without its written



                                       52
<PAGE>   60

consent, which shall not be unreasonably withheld. The Company need not
reimburse any expense or indemnify against any loss or liability to the extent
incurred by the Trustee through its negligence, bad faith or willful misconduct.

        To secure the Company's payment obligations in this Section 7.7, the
Trustee shall have a lien prior to the Notes on all assets held or collected by
the Trustee, in its capacity as Trustee, except assets held in trust to pay
principal (and premium, if any,) or interest on particular Notes.

        When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.1(e) or Section 6.1(f) occurs, the expenses and
the compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

        The Company's obligations under this Section 7.7 and any lien arising
hereunder shall survive the resignation or removal of the Trustee, the discharge
of the Company's obligations pursuant to Article VIII and any rejection or
termination of this Indenture under any Bankruptcy Law.

        Section 7.8 Replacement of Trustee. The Trustee may resign by so
notifying the Company in writing. The Holder or Holders of a majority in
principal amount of the outstanding Notes may remove the Trustee by so notifying
the Company and the Trustee in writing and may appoint a successor trustee with
the Company's consent. The Company may remove the Trustee if:

        (1) the Trustee fails to comply with Section 7.10;

        (2) the Trustee is adjudged bankrupt or insolvent;

        (3) a receiver, Custodian, or other public officer takes charge of the
Trustee or its property; or

        (4) the Trustee becomes incapable of acting.

        If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holder or
Holders of a majority in principal amount of the Notes may appoint a successor
Trustee to replace the successor Trustee appointed by the Company.

        A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after that
and provided, however, that all sums owing to the Trustee provided for in
Section 7.7 have been paid, the retiring Trustee shall transfer all property
held by it as Trustee to the successor Trustee, subject to the lien provided in
Section 7.7, the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee shall have all the rights, powers and
duties of the Trustee under this Indenture. A successor Trustee shall mail
notice of its succession to each Holder.

        If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holder or Holders of at least 10% in principal amount of the outstanding Notes
may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

        If the Trustee fails to comply with Section 7.10, any Noteholder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.




                                       53
<PAGE>   61

        Notwithstanding replacement of the Trustee pursuant to this Section 7.8,
the Company's obligations under Section 7.7 shall continue for the benefit of
the retiring Trustee.

        Section 7.9 Successor Trustee by Merger, Etc. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all of its corporate trust business to, another corporation, the resulting,
surviving or transferee corporation without any further act shall, if such
resulting, surviving or transferee corporation is otherwise eligible hereunder,
be the successor Trustee.

        Section 7.10 Eligibility; Disqualification. The Trustee shall at all
times satisfy the requirements of TIA ss.ss. 310(a)(1), 310(a)(2) and 310(a)(5).
The Trustee shall comply with TIA ss. 310(b).

        Section 7.11 Preferential Collection of Claims against Company. The
Trustee shall comply with TIA ss. 311(a), excluding any creditor relationship
listed in TIA ss. 311(b). A Trustee who has resigned or been removed shall be
subject to TIA ss. 311(a) to the extent indicated.

        Section 7.12 No Bond. The Trustee shall not be required to give any
bond or surety in respect to the execution of its trusts, powers, rights and
duties under this Indenture or otherwise in respect of the premises.

        Section 7.13 Condition to Action. Notwithstanding anything elsewhere
in this Indenture to the contrary, the Trustee shall have the right, but shall
not be required, to demand, in respect of the authentication of any Notes or any
other action within the purview of this Indenture, any showings, certificates,
opinions, or other information, or corporate action or evidence thereof in
addition to that by the terms hereof required, as a condition of such action by
the Trustee if reasonably deemed desirable by the Trustee for the purpose of
establishing the right to the authentication of any Notes or the taking of any
other action by the Trustee.

        Section 7.14 Investment. The Trustee shall not be responsible or
liable for any loss suffered in connection with any investment of funds made by
it at the direction of the Company.

                                  ARTICLE VIII

                       LEGAL DEFEASANCE AND COVENANT DEFEASANCE

        Section 8.1 Option to Effect Legal Defeasance or Covenant Defeasance.
The Company may, at its option at any time within the final year of the Stated
Maturity of the Notes, elect to have Section 8.2 or, at any time, Section 8.3
applied to all outstanding Notes upon compliance with the conditions set forth
below in this Article VIII.

        Section 8.2 Legal Defeasance and Discharge. Upon the Company's
exercise under Section 8.1 of the option applicable to this Section 8.2, the
Company shall be deemed to have been discharged from its obligations with
respect to all outstanding Notes on the date the conditions set forth below are
satisfied (hereinafter, "Legal Defeasance"). For this purpose, such Legal
Defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented by the outstanding Notes, which shall
thereafter be deemed to be "outstanding" only for the purposes of Section 8.5
and the other Sections of this Indenture referred to in (a) and (b) below, and
to have satisfied all its other obligations under such Notes and this Indenture
(and the Trustee, on demand of and at the expense of the Company, shall execute
proper instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (a) the rights of
Holders of outstanding Notes to receive solely from the trust fund described in
Section 8.4, and as more fully set forth in such section, payments in respect of
the principal of, premium, if any, and interest on such Notes when such payments
are due, (b) the Company's obligations with



                                       54
<PAGE>   62

respect to such Notes under Sections 2.4, 2.6, 2.7, 2.10 and 5.2, (c) the
rights, powers, trusts, duties and immunities of the Trustee hereunder and the
Company's obligations in connection therewith and (d) this Article VIII. Subject
to compliance with this Article VIII, the Company may exercise its option under
this Section 8.2 notwithstanding the prior exercise of its option under Section
8.3 with respect to the Notes.

        Section 8.3 Covenant Defeasance. Upon the Company's exercise under
Section 8.1 of the option applicable to this Section 8.3, the Company shall be
released from its obligations under the covenants contained in Sections 4.3,
4.6, 4.7, 4.8, 4.10, 4.11, 4.12, 4.13, 4.14, 4.16, 4.17, 4.18, and 4.19 and
Article V, and in the Security Documents with respect to the outstanding Notes
on and after the date the conditions set forth below are satisfied (hereinafter,
"Covenant Defeasance"), and the Notes shall thereafter be deemed not
"outstanding" for the purposes of any direction, waiver, consent or declaration
or act of Holders (and the consequences of any thereof) in connection with such
covenants, but shall continue to be deemed "outstanding" for all other purposes
hereunder. For this purpose, such Covenant Defeasance means that, with respect
to the outstanding Notes, the Company need not comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document, but, except as specified
above, the remainder of this Indenture and such Notes shall be unaffected
thereby. In addition, upon the Company's exercise under Section 8.1 of the
option applicable to this Section 8.3, Sections 6.1(c) (with respect to the
covenants referenced in the first sentence of this Section 8.3) through 6.1(h)
shall not constitute Events of Default.

        Section 8.4 Conditions to Legal or Covenant Defeasance. The following
shall be the conditions to the applicable of either Section 8.2 or Section 8.3
to the outstanding Notes:

        (a) The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee satisfying the requirements of
Section 7.10 who shall agree to comply with the provisions of this Article VIII
applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefit of the Holders of such Notes, (a) U.S. Legal Tender in an
amount, or (b) U.S. Government Obligations which through the scheduled payment
of principal and interest in respect thereof in accordance with their terms will
provide, not later than one day before the due date of any payment, U.S. Legal
Tender in an amount, or (c) a combination thereof, in such amounts, as in each
case will be 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 and which shall be supplied by
the Trustee (or other qualifying trustee) to pay and discharge (i) the principal
of, premium, if any, and interest on the outstanding Notes on the stated
maturity or on the applicable redemption date, as the case may be, of such
principal or installment of principal, premium, if any, or interest; provided
that the Trustee shall have been irrevocably instructed to apply such Legal
Tender and the proceeds of such U.S. Government obligations to said payments
with respect to the Notes.

        (b) In the case of an election under Section 8.2, the Company shall have
delivered to the Trustee an Opinion of counsel in the United States reasonably
satisfactory to the Trustee confirming that (i) the Company has received from,
or there has been published by, the Internal Revenue Service a ruling or (ii)
since the date hereof, there has been a change in the applicable Federal income
tax law, in either case to the effect that, and based thereon such opinion shall
confirm that, the Holders of the outstanding Nots will not recognize income,
gain or loss for Federal income tax purposes as a result of such Legal
Defeasance and will be subject to Federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such Legal
Defeasance has not occurred;

        (c) In the case of an election under Section 8.3, the Company shall have
delivered to the Trustee an Opinion of Counsel in the United States to the
effect that the Holders of the outstanding Notes will


                                       55
<PAGE>   63

not recognize income, gain or loss for Federal income tax purposes as a result
of such Covenant Defeasance and will be subject to Federal income tax in the
same amount, in the same manner and at the same times as would have been the
case if such Covenant Defeasance had not occurred;

        (d) No Default or Event of Default with respect to the Notes shall have
occurred and be continuing on the date of such deposit or, in so far as Sections
6.2(e) or 6.2(f) is concerned, at any time in the period ending on the 91st day
after the date of such deposit (it being understood that this condition shall
not be deemed satisfied until the expiration of such period);

        (e) Such Legal Defeasance or Covenant Defeasance shall not result in a
breach or violation of, or constitute a default under, this Indenture or any
other material agreement or instrument to which the Company, the Guarantors, or

        (f) In the case of an election under either Section 8.2 or 8.3, the

or 8.3 was not made by the Company with the intent of preferring the Holders
over other creditors of the Company or with the intent of defeating, hindering,
delaying or defrauding creditors of the Company or others; and

        (g) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel in the United States, each stating that
all conditions precedent providing for relating to either the Legal Defeasance
under Section 8.2 or the Covenant Defeasance under Section 8.3 (as the case may
be) have been complied with as contemplated by this Section 8.4.

        Section 8.5 Deposited U.S. Legal Tender and U.S. Government
Obligations to be Held in Trust; Other Miscellaneous Provisions. Subject to
Section 8.6, all U.S. Legal Tender and U.S. Government Obligations (including
the proceeds thereof) deposited with the Trustee (or other qualifying trustee,
collectively for purposes of this Section 8.5, the "Trustee") pursuant to
Section 8.4 in respect of the outstanding Notes shall be held in trust and
applied by the Trustee, in accordance with the provisions of such Notes and this
Indenture, to the payment, either directly or through any Paying Agent as the
Trustee may determine, to the Holders of such Nots of all sums due and to become
due thereon in respect of principal, premium, if any, and interest, but such
money need not be segregated from other funds except to the extent required by
law.

        Anything in this Article VIII to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the request
of the Company any U.S. Legal Tender or U.S. Government Obligations held by it
as provided in Section 8.4 which, in the opinion of a nationally recognized firm
of independent public accountants expressed in written certification thereto
delivered to the Trustee (which may be the opinion delivered upon Section
8.4(a)), are in excess of the amount thereof which would then be required to be
deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

        Section 8.6 Repayment to Issuers. Any money deposited with the
Trustee or any Paying Agent, or then held by the Company, in trust for the
payment for the principal of premium, if any, or interest on any Notes and
remaining unclaimed for two years after such principal, and premium, if any, or
interest has become due and payable shall be paid to the Company on its request;
and the Holder of such Notes shall thereafter look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money shall thereupon cease; provided, however, that the
Trustee or such Paying Agent before being required to make any such repayment,
may at the expense of the Company cause to be published once, in the New York
Times and The Wall Street Journal (national edition), notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from



                                       56
<PAGE>   64

the date of such notification or publication, any unclaimed balance of such
money then remaining will be repaid to the Issuers.

        Section 8.7 Reinstatement. If the Trustee or Paying Agent is unable
to apply any U.S. Legal Tender or U.S. Government Obligations in accordance with
Section 8.2 or 8.3, as the case may be, by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, the Company's obligations under this Indenture and
the Notes shall be revived and reinstated as though no deposit had occurred
pursuant to Section 8.2 or Section 8.3 until such time as the Trustee or Paying
Agent is permitted to apply all such money in accordance with Section 8.2 or
Section 8.3, as the case may be; provided, however, that if the Company makes
any payment of principal of, premium, if any, or interest on any Notes because
of the reinstatement of its obligations, the Company shall be subrogated to the
rights of the Holders of such Notes to receive such payment from the Cash held
by the Trustee or Paying Agent.

        Section 8.8 Termination of Obligations Upon Cancellation of the Notes.
In addition to the Company's rights under Sections 8.2 and 8.3, the Company and
the Guarantors may terminate all of their obligations under this Indenture and
this Indenture shall be deemed satisfied and discharged (in each case subject to
Section 8.7) when:

               (1) all Notes theretofore authenticated and delivered (other than
        Notes which have been destroyed, lost or stolen and which have been
        replaced or paid as provided in Section 2.7) have been delivered to the
        Trustee for cancellation, and the Company or a Guarantor has paid or
        caused to be paid all sums payable hereunder by the Company; or

               (2) (i) all Notes not heretofore delivered to the Trustee for
        cancellation otherwise have become due and payable or, within 30 days
        will become due and payable or subject to redemption as set forth under
        Article III and the Company has irrevocably deposited or caused to be
        deposited with the Trustee as trust funds in the trust for such purpose
        an amount of money sufficient to pay and discharge the entire
        indebtedness on the Notes not heretofore delivered to the Trustee for
        cancellation, including all principal, premium, if any, and accrued
        interest (and liquidated damages, if any), (ii) the Company has paid all
        sums payable by it under this Indenture, (iii) the Company has delivered
        irrevocable instructions to the Trustee to apply the deposited money
        toward the payment of the Notes at the Maturity Date, and (iv) the
        Holders of the Notes have a valid perfected, exclusive security interest
        in such trust.

        In addition, the Company shall deliver to the Trustee an Officers'
Certificate and an Opinion of Counsel (who is not in-house counsel to the
Company or any of its Subsidiaries), each stating that all conditions precedent
specified herein relating to the satisfaction and discharge of this Indenture
have been complied with and that such satisfaction and discharge will not result
in a breach or violation of, or constitute a Default under, this Indenture or
any other instrument to which the Company, any Guarantor or any of their
Subsidiaries is a party or by which it or their property is bound.

                                   ARTICLE IX

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

        Section 9.1 Supplemental Indentures Without Consent of Holders. Without
the consent of any Holder, the Company, when authorized by Board Resolutions,
and the Trustee, at any time and from time to


                                       57
<PAGE>   65

time, may enter into one or more indentures supplemental hereto or a restatement
hereof or amendments to or restatements of any one or more of the Security
Documents, in form satisfactory to the Trustee, for any of the following
purposes:

               (a) to cure any ambiguity, defect, or inconsistency, or to make
        any other provisions with respect to matters or questions arising under
        this Indenture or any one or more of the Security Documents which shall
        not be inconsistent with the provisions of this Indenture, provided,
        however, that such action pursuant to this clause (a) shall not
        adversely affect the interests of any Holder in any respect;

               (b) to add to the covenants of the Company for the benefit of the
        Holders or to surrender any right or power herein conferred upon the
        Company or to make any other change that does not adversely affect the
        rights of any Holder, provided, however, that the Company has delivered
        to the Trustee an Opinion of Counsel stating that such change does not
        adversely affect the rights of any Holder;

               (c) to provide for additional collateral for the Notes;

               (d) to evidence the succession of another Person to the Company
        and the assumption by any such successor of the obligations of the
        Company herein and in the Notes in accordance with Article V;

               (e) to comply with the TIA; or

               (f) to restate this Indenture or any one or more of the Security
        Documents so that it reflects this Indenture or such Security Document,
        as the case may be, as originally executed as amended by all amendments
        and supplements hereto or thereto through the date of such restatement
        and contains only the then effective provisions of this Indenture or
        such Security Document, as the case may be.


        Section 9.2 Amendments, Supplemental Indentures and Waivers with
Consent of Holders. Subject to Section 6.8 and the last sentence of this
paragraph, with the consent of the Holders of not less than 662/3% in aggregate
principal amount of then outstanding Notes, by written act of said Holders
(including an electronic mechanism utilized by the Depository Trust Company as a
means of receiving consents or tenders of securities) delivered to the Company
and the Trustee, the Company, when authorized by Board Resolutions, and the
Trustee may amend or supplement this Indenture, the Notes or any of the Security
Documents or enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to or changing in any manner or eliminating, or
waiving compliance with, any of the provisions of this Indenture or the Notes or
of modifying in any manner the rights of the Holders under this Indenture or the
Notes, provided, however, that no such amendment, waiver or modification may,
without the consent of the Holders of not less than 75% in aggregate principal
amount of the Notes at the time outstanding, (i) amend, waive or modify the
provisions (including the definitions of the defined terms used therein) of
Sections 4.3, 4.11, 4.13, 4.14 or 4.16, or of Articles XI or XII, in a manner
adverse to the Holders, or (ii) amend or supplement any of the Security
Documents in a manner adverse to the Holders. Notwithstanding any of the above,
however, no such amendment, supplemental indenture or waiver shall, without the
consent of the Holder of each outstanding Note affected thereby:





                                       58
<PAGE>   66


        (a) change the Stated Maturity or the payment date of any installment of
principal of, or the payment date of any installment of interest on, any Note;

        (b) reduce the principal amount of any Note or the rate of interest
thereon or any premium payable upon the redemption thereof;

        (c) make the principal of, or the interest on, any Note payable with
anything or in any manner other than as provided for in this Indenture
(including changing the place of payment where, or the coin or currency in
which, any Note or any premium or the interest thereon is payable) and the Notes
as in effect on the date hereof;

        (d) reduce the percentage of principal amount of Notes whose Holders
must consent to an amendment, supplement or waiver of any provision of this
Indenture or the Notes;

        (e) reduce the rate or extend the time for payment of interest on any
Note;

        (f) (i) alter the redemption provisions (including the definitions of
the defined terms used therein) of Article III or of Paragraph 5 of the Notes,
or (ii) after the date upon which a Change of Control Offer (as defined in
Section 13.1(b)) is required to be made, reduce the Change of Control Purchase
Price (as defined in Section 13.1(a)) or otherwise alter the terms or provisions
of Article XIII; in any case, in a manner adverse to any Holder;

        (g) make any changes in the provisions concerning waivers of Defaults or
Events of Default by Holders of the Notes (except to increase any required
percentage or to provide that certain other provisions hereof cannot be modified
or waived without the consent of the Holders of each outstanding Note affected
thereby) or the rights of Holders to recover the principal or premium of,
interest on, or redemption payment with respect to, any Note;

        (h) make any changes that would subordinate the Notes in right of
payment to the payment of any other Debt of the Company or any of its
Subsidiaries (except as expressly provided in Section 11.2 or Section 11.5); or

        (i) make any changes in Section 6.4, 6.7 or this third sentence of this
Section 9.2.

        It shall not be necessary for the consent of the Holders under this
Section to approve the particular form of any proposed amendment, supplement or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

        After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders 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 amendment, supplement or waiver.

        After an amendment, supplement or waiver under this Section 9.2 or
Section 9.4 becomes effective, it shall bind each Holder.





                                       59
<PAGE>   67


        In connection with any amendment, supplement or waiver under this
Article IX, the Company may, but shall not be obligated to, offer to any Holder
who consents to such amendment, supplement or waiver, consideration for such
Holder's consent to such amendment, supplement or waiver; provided, that such
consideration is offered to all Holders and paid to all Holders who consent; and
provided further, that notwithstanding the preceding proviso, the Company shall
only be required to offer such consideration for the consent of a Holder if the
solicitation of such consent does not require registration under the Exchange
Act or any applicable state securities laws.


        Section 9.3 Compliance with TIA. Every amendment, waiver or supplement
of this Indenture or the Notes shall comply with the TIA as then in effect.

        Section 9.4 Revocation and Effect of Consents. Until an amendment,
waiver or supplement becomes effective, a consent to it by a Holder is a
continuing consent by the Holder and every subsequent Holder of a Note or
portion of a Note that evidences the same debt as the consenting Holder's Note,
even if notation of the consent is not made on any Note. However, any such
Holder or subsequent Holder may revoke the consent as to his Note or portion of
his Note by written notice to the Company or the Person designated by the
Company as the Person to whom consents should be sent if such revocation is
received by the Company or such Person before the date on which the Trustee
receives an Officers' Certificate certifying that the Holders of the requisite
principal amount of Notes have consented (and not theretofore revoked such
consent) to the amendment, supplement or waiver.

        The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver, which record date shall be the date so fixed by the
Company notwithstanding the provisions of the TIA. If a record date is fixed,
then notwithstanding the last sentence of the immediately preceding paragraph,
those Persons who were Holders at such record date, and only those Persons (or
their duly designated proxies), shall be entitled to revoke any consent
previously given, regardless of whether such Persons continue to be Holders
after such record date. No such consent shall be valid or effective for more
than 90 days after such record date.

        After an amendment, supplement or waiver becomes effective, it shall
bind every Noteholder; provided, however, that any such waiver shall not impair
or affect the right of any Holder to receive payment of principal and premium of
and interest on a Note, on or after the respective dates set for such amounts to
become due and payable expressed in such Note, or to bring suit for the
enforcement of any such payment on or after such respective dates.

        Section 9.5 Notation on or Exchange of Notes. If an amendment,
supplement or waiver changes the terms of a Note, the Trustee may require the
Holder of the Note to deliver it to the Trustee or require the Holder to put an
appropriate notation on the Note. The Trustee may place an appropriate notation
on the Note about the changed terms and return it to the Holder. Alternatively,
if the Company or the Trustee so determines, the Company in exchange for the
Note shall issue and the Trustee shall authenticate a new Note that reflects the
changed terms. Any failure to make the appropriate notation or to issue a new
Note shall not affect the validity of such amendment, supplement or waiver.

        Section 9.6 Trustee to Sign Amendments, Etc. The Trustee shall execute
any amendment, supplement, restatement or waiver authorized pursuant to this
Article IX, provided, however, that the Trustee may, but shall not be obligated
to, execute any such amendment, supplement, restatement or waiver which affects
the Trustee's own rights, duties or immunities under this Indenture. The Trustee
at the expense of the



                                       60
<PAGE>   68

Company shall be entitled to receive, and shall be fully protected in relying
upon, an Opinion of Counsel stating that the execution of any amendment,
supplement, restatement or waiver authorized pursuant to this Article IX is
authorized or permitted by this Indenture.

                                    ARTICLE X

        Section 10.1 Purposes for Which Meetings May Be Called. A meeting of
Noteholders may be called at any time and from time to time pursuant to the
provisions of this Article X for any of the following purposes:

        (a) to give any notice to the Company or to the Trustee, or to give any
directions to the Trustee, or to waive or to consent to the waiving of any
Default or Event of Default hereunder and its consequences, or to take any other
action authorized to be taken by Noteholders pursuant to any of the provisions
of Article VI;

        (b) to remove the Trustee or appoint a successor Trustee pursuant to the

        (d) to take any other action (i) authorized to be taken by or on behalf
of the Holder or Holders of any specified aggregate principal amount of the
Notes under any other provision of this Indenture, or authorized or permitted by
law, or (ii) which the Trustee deems necessary or appropriate in connection with
the administration of this Indenture.

        Section 10.2 Manner of Calling Meetings. The Trustee may at any time
call a meeting of Noteholders to take any action specified in Section 10.1, to
be held at such time and at such place in the City of New York, New York or
elsewhere as the Trustee shall determine. Notice of every meeting of
Noteholders, setting forth the time and place of such meeting and in general
terms the action proposed to be taken at such meeting, shall be mailed by the
Trustee, first-class postage prepaid, to the Company and to the Holders at their
last addresses as they shall appear on the registration books of the Registrar,
not less than 10 nor more than 60 days prior to the date fixed for a meeting.

        Any meeting of Noteholders shall be valid without notice if the Holders
of all Notes then outstanding are present in Person or by proxy, or if notice is
waived before or after the meeting by the Holders of all Notes outstanding, and
if the Company and the Trustee are either present by duly authorized
representatives or have, before or after the meeting, waived notice.

        Section 10.3 Call of Meetings by Company or Holders. In case at any time
the Company, pursuant to a Board Resolution, or the Holders of not less than 25%
in aggregate principal amount of the Notes then outstanding, shall have
requested the Trustee to call a meeting of Noteholders to take any action
specified in Section 10.1, by written request setting forth in reasonable detail
the action proposed to be taken at the meeting, and the Trustee shall not have
mailed the notice of such meeting within 20 days after receipt of such request,
then the Company or the Holders of Notes in the amount above specified may
determine the time and place in the City of New York, New York or elsewhere for
such meeting and may call such meeting for the purpose of taking such action, by
mailing or causing to be mailed notice thereof as provided in Section 10.2, or
by causing notice thereof to be published at least once in each of two
successive calendar weeks (on any



                                       61
<PAGE>   69

Business Day during such week) in a newspaper or newspapers printed in the
English language, customarily published at least five days a week of a general

publication to be not less than 10 nor more than 60 days prior to the date fixed
for the meeting.

        Section 10.4 Who May Attend and Vote at Meetings. To be entitled to vote
at any meeting of Noteholders, a Person shall (a) be a registered Holder of one
or more Notes, or (b) be a Person appointed by an instrument in writing as proxy
for the registered Holder or Holders of Notes. The only Persons who shall be
entitled to be present or to speak at any meeting of Noteholders shall be the
Persons entitled to vote at such meeting and their counsel and any

Company and its counsel.

        Section 10.5 Regulations May Be Made by Trustee; Conduct of the Meeting;
Voting Rights; Adjournment. Notwithstanding any other provision of this
Indenture, the Trustee may make such reasonable regulations as it may deem
advisable for any action by or any meeting of Noteholders, in regard to proof of
the holding of Notes and of the appointment of proxies, and in regard to the
appointment and duties of inspectors of votes, and submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall think appropriate.
Such regulations may fix a record date and time for determining the Holders of
record of Notes entitled to vote at such meeting, in which case those and only
those Persons who are Holders of Notes at the record date and time so fixed, or
their proxies, shall be entitled to vote at such meeting regardless of whether
they shall be such Holders at the time of the meeting.

        The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Noteholders as provided in Section 10.3, in which case the Company
or the Noteholders calling the meeting, as the case may be, shall in like manner
appoint a temporary chairman. A permanent chairman and a permanent secretary of
the meeting shall be elected by vote of the Holders of a majority in principal
amount of the Notes represented at the meeting and entitled to vote.

        At any meeting each Noteholder or proxy shall be entitled to one vote
for each $1,000 principal amount of Notes held or represented by him; provided,
however that no vote shall be cast or counted at any meeting in respect of any
Notes challenged as not outstanding and ruled by the chairman of the meeting to
be not then outstanding. The chairman of the meeting shall have no right to vote
other than by virtue of Notes held by him or instruments in writing as aforesaid
duly designating him as the proxy to vote on behalf of other Noteholders. Any
meeting of Noteholders duly called pursuant to the provisions of Section 10.2 or
Section 10.3 may be adjourned from time to time by vote of the Holder or Holders
of a majority in aggregate principal amount of the Notes represented at the
meeting and entitled to vote, and the meeting may be held as so adjourned
without further notice.

        Section 10.6 Voting at the Meeting and Record to Be Kept. The vote upon
any resolution submitted to any meeting of Noteholders shall be by written
ballots on which shall be subscribed the signatures of the Holders of Notes or
of their representatives by proxy and the principal amount of the Notes voted by
the ballot. The permanent chairman of the meeting shall appoint two inspectors
of votes, who shall count all votes cast at the meeting for or against any
resolution and who shall make and file with the secretary of the meeting their
verified written reports in duplicate of all votes cast at the meeting. A record
in duplicate of the proceedings of each meeting of Noteholders shall be prepared
by the secretary of the meeting and there shall be attached to such record the
original reports of the inspectors of votes on any vote by ballot taken



                                       62
<PAGE>   70

thereat and affidavits by one or more Persons having knowledge of the facts,
setting forth a copy of the notice of the meeting and showing that such notice
was mailed as provided in Section 10.2 or published as provided in Section 10.3.
The record shall be signed and verified by the affidavits of the permanent
chairman and the secretary of the meeting and one of the duplicates shall be
delivered to the Company and the other to the Trustee to be preserved by the
Trustee, the latter to have attached thereto the ballots voted at the meeting.

        Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

        Section 10.7 Exercise of Rights of Trustee or Noteholders May Not Be
Hindered or Delayed by Call of Meeting. Nothing contained in this Article X
shall be deemed or construed to authorize or permit, by reason of any call of a
meeting of Noteholders or any rights expressly or impliedly conferred hereunder
to make such call, any hindrance or delay in the exercise of any right or rights
conferred upon or reserved to the Trustee or to the Noteholders under any of the
provisions of this Indenture or of the Notes.


                                   ARTICLE XI

                                    SECURITY


        Section 11.1 Grant of Security Interest. In order to secure the payment
and performance of all obligations of the Company with respect to the Notes
including the due and punctual payment of the principal of, interest on and
premium, if any, on the Notes when and as the same shall become due and payable,
whether on an interest payment date, at a Maturity Date, by acceleration, call
for redemption or otherwise, and interest on the overdue principal and interest,
if any, of the Notes, each of the Company and each Guarantor hereby covenants to
execute, deliver and file of record for the benefit of the Holders, the Security
Documents to which it is a party and this Indenture. The Security Documents
shall grant to the Trustee a security interest in the collateral therein
described and when filed shall be deemed hereby incorporated by reference herein
to the same extent and as fully as if set forth in their entirety at this place,
and reference is made hereby to each Security Document for a more complete
description of the terms and provisions thereof. Each Holder, by accepting a
Note, agrees to all of the terms and provisions of the Security Documents and
the Trustee agrees to all of the terms and provisions of the Security Documents
signed by it.

        Section 11.2 Trustee's Execution of Intercreditor Agreements and
Subordination Agreements.

        (a) The Trustee, at the Company's expense, will execute, deliver, file
and record, all instruments and do all acts and other things as may be
reasonably necessary to provide pursuant to the Intercreditor Agreement(s) among
other things, that (i) the Liens securing the Security Interests will be junior
to the Liens on Shared Collateral securing the Debt and other obligations of the
Company under the Extended DIP Facility and under the Post Confirmation Credit
Facility, (ii) that in the event of any judicial or non-judicial foreclosure (or
conveyance in lieu thereof), any cash or other assets paid by reason thereof
will be applied, after payment of reasonable costs and expenses relating to
obtaining such proceeds, to the payment of the Debt outstanding under the
Extended DIP Facility and to the payment of the Debt outstanding under the Post
Confirmation Credit Facility, as the case may be, and only after the Debt
outstanding under the Extended DIP Facility and to the payment of the Debt
outstanding under the Post Confirmation Credit Facility, as the case may be, has
been paid in full, to the payment of the Notes, and (iii) that determinations
regarding the exercise of remedies against the Shared Collateral will be made by
the holders of not less than 75% of the outstanding principal amount of [ ]. The
Intercreditor Agreements will provide that




                                       63
<PAGE>   71


nothing contained therein will impair or affect the right of the Holders of the
Notes to institute suit for the enforcement of any payment thereon as and when
due.

        (b) Upon receipt of a Subordination Request, the Trustee (and any
lender, trustee or collateral agent under or with respect to any of the Security
Documents), at the Company's expense, will execute and deliver, within five
Business Days from the receipt of such Subordination Request, any instruments
deemed by the Company (or with respect to the Security Documents, the grantor of
the Security Interest thereunder) to be reasonably necessary or reasonably
appropriate to subordinate the Security Interests to any Lien accorded priority
over the Security Interests by the Plan or by a Plan Order, but only to the
extent, and only with respect to such Collateral as to which, such priority is
accorded, if the provisions of this Section 11.2(b) have been complied with. Any
such Subordination Request shall request the Trustee (and any such lender,
trustee or collateral agent under or with respect to any of the Security
Documents) to execute one or more specifically described instruments of
subordination (which instruments of subordination accompany such Subordination
Request) and shall certify that (i) the Lien to which the Security Interests are
to be subordinated is a Lien accorded priority over the Security Interests by
the Plan or a Plan Order, and (ii) that the subordination requested effects a
subordination of the Security Interests only to the extent, and only with
respect to Collateral as to which such subordination is, contemplated by the
provision of the Plan or the Plan Order on which the subordination requested is
based.

        (c) Upon receipt of a Subordination Request, the Trustee (and any
lender, trustee or collateral agent under or with respect to any of the Security
Documents), at the Company's expense, will execute and deliver, within five
Business Days from the receipt of such Subordination Request, any instruments
deemed by the Company (or with respect to the Security Documents, the grantor of
the Security Interest thereunder) to be reasonably necessary or reasonably
appropriate to subordinate the Security Interests to Permitted Liens securing
any First Lien Debt, if the provisions of this Section 11.2(c) have been
complied with. Any such Subordination Request shall request the Trustee (and any
such lender, trustee or collateral agent under or with respect to any of the
Security Documents) to execute one or more specifically described instruments of
subordination (which instruments of subordination accompany such Subordination
Request) and shall certify (1) that no Event of Default has occurred and is
continuing, and (2) that one of the conditions set forth below in clause (i) or

               (ii) Holders of not less than 75% of principal amount of the then

        Asset Sale made in compliance with Section 4.14;

               (iv) all of the conditions precedent to the termination of the
        Security Document under which the Lien in the Collateral to be released

                                       66
<PAGE>   74


               (v) Holders of not less than 75% in principal amount of the then

        Collateral from the Security Interests;

               (vi) the Collateral to be released secures debt or other
        obligations that constitute First Lien Debt and the Company (or with
        respect to releases under the Security Documents, the grantor of the
        Security Interest thereunder) has satisfied all the requirements for
        obtaining subordination of the Security Interests therein pursuant to
        Section 11.2(b) and such Collateral is (or will be, upon obtaining such
        release) encumbered by a Lien permitted pursuant to the terms of clauses
        (j), (l), or (o) of the definition of Permitted Liens; or

               (vii) the release of the Collateral to be released is required
        pursuant to, or is required in order to effect compliance with, the Plan
        or a Plan Order.

        (b) As a condition to any release of Collateral under this Section 11.5,
the Company shall deliver to the Trustee any certificate or opinion required by
TIA ss. 314(d), as to the fair value of any Collateral to be released, or by TIA
ss. 314(c), as to the fulfillment of any condition precedent to such release,
dated as of a date not more than 60 days prior to the date of substitution or
release. Such certificate or opinion shall state that the proposed release of
Collateral will not impair the Security Interests in contravention of the
provisions of this Indenture. The Person delivering such certificate or opinion
must be independent with respect to the Company if required by TIA ss. 314(d).

        (c) At the request of the Company (or with respect to releases under the
Security Documents, the grantor of the Security Interest thereunder), the
Trustee shall, in lieu of releasing any Collateral pursuant to this Section
11.5, execute and deliver a Subordination Agreement with respect to such
Collateral.

        (d) Any release or subordination of Collateral made in compliance with
the provisions of this Section 11.5 shall be deemed not to impair the Security
Interests in contravention of the provisions of this Indenture.

        Section 11.6 Release Upon Defeasance or Satisfaction and Discharge of
this Indenture.

certifying that all of the provisions of either Section 8.2, Section 8.3 or
Section 8.8 have been satisfied, the Trustee shall disclaim and give up any and
all rights it has in or to the Collateral, and any rights it has under the
Security Documents (subject to Section 8.7).

        (b) Any release of Collateral made in compliance with the provisions of
this Section 11.6 shall be deemed not to impair the Security Interests in

        Section 11.7 Reliance on Opinion of Counsel. The Trustee shall, before
taking any action under this Article XI, be entitled to receive an Opinion of
Counsel at the expense of the Company, stating the legal effect of such action,
and that such action will not be in contravention of the provisions hereof, and
such opinion shall be full protection to the Trustee for any action taken or
omitted to be taken in reliance thereon; provided, however, that the Trustee's
action under this Article XI shall at all times be and remain subject to its
duties and protections under Article VII.

        Section 11.8 Purchaser May Rely. A purchaser in good faith of the
Collateral or any part thereof or interest therein which is purported to be
transferred, granted or released by the Trustee as provided in this Article XI
(i) shall not be obligated to ascertain the validity of the transfer, grant or
release, and may rely on the authority of the Trustee to execute the document
evidencing such transfer, grant or release, (ii) shall not be obligated to
inquire as to the satisfaction of any conditions precedent to the exercise of
such authority, and (iii) shall not be obligated to determine whether the
application of the purchase price therefor complies with the terms hereof.

        Section 11.9 Payment of Expenses. Without limiting Section 7.7, on
demand of the Trustee, the Company forthwith shall pay or satisfactorily provide
for all reasonable expenditures incurred by the Trustee under this Article XI.
In the event that the Company (or with respect to any Security Documents, the
grantor of the Security Interest thereunder) makes a Release Request more often
than once a month, the Trustee and the Company shall negotiate an additional
reasonable fee for each such request. All such sums referred to in this Section
11.9 shall be a Lien upon the Collateral and shall be secured thereby.

        Section 11.10 Trustee's Duties. The powers and duties conferred upon the
Trustee by this Article XI are solely to protect the Security Interests and
shall not impose any duty upon the Trustee to exercise any such powers except as
expressly provided in this Indenture. The Trustee shall be under no duty to the
Company (or with respect to any Security Documents, the grantor of the Security
Interest thereunder) whatsoever to make or give any presentment, demand for
performance, notice of non-performance, protest, notice of protest, notice of
dishonor, or other notice or demand in connection with any Collateral, or to
take any steps necessary to preserve any rights against prior parties except as
expressly provided in this Indenture. The Trustee shall not be liable to the
Company (or with respect to any Security Documents, the grantor of the Security
Interest thereunder) for failure to collect or realize upon any or all of the
Collateral, or for any delay in so doing, nor shall the Trustee be under any
duty to the Company (or with respect to any Security Documents, the grantor of
the Security Interest thereunder) to take any action whatsoever with regard
thereto. The Trustee shall have no duty to the Company (or with respect to any
Security Documents, the grantor of the Security Interest thereunder) to comply
with any recording, filing, or other legal requirements necessary to establish
or maintain the validity, priority or enforceability of the Security Interests
in, or the Trustee's rights in or to, any of the Collateral.

        Section 11.11 Authorization of Actions to be Taken by the Trustee Under
the Security Documents. The Trustee may, in its sole discretion and without the
consent of the Holders, but subject to Article VII and the terms of the
Intercreditor Agreements, take all actions it deems necessary or appropriate in
order to enforce or effect the Security Documents. Such actions shall include,
but not be limited to, enforcing or effecting any term or provision of the
Security Documents or advising, instructing or otherwise directing the
collateral agent or other appropriate Person under any Intercreditor Agreement
with respect to the enforcement of any right or remedy with respect to
Collateral and/or any term or provision of the Security Documents. Subject to
the provisions of the Security Documents (and the Intercreditor Agreements), the
Trustee shall have the power to institute and to maintain such suits and
proceedings as it may deem expedient to prevent any impairment of the Collateral
by any acts which may be unlawful or in violation of the Security Documents or
this Indenture, and such suits and proceedings as the Trustee may deem expedient
to preserve or protect its interests and the interests of the Holders in the
Collateral (including power to institute and maintain suits or proceedings to
restrain the enforcement of or compliance with any legislative or other
governmental enactment, rule or order that may be unconstitutional or otherwise
invalid if the enforcement of, or compliance with, such enactment, rule or order
would impair the security hereunder or be prejudicial to the interests of the
Holders or of the Trustee). In addition, the Trustee may act upon any
Subordination

Request or Release Request by the Company (or with respect to any Security
Documents, the grantor of the Security Interest thereunder) on behalf of the
Company.


                                   ARTICLE XII

                                    GUARANTEE


        Section 12.1  Guarantee.

        (a) In consideration of good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, each Subsidiary of the Company
joining in the execution of this Indenture and the Notes for the purpose of
evidencing its Guarantee and its agreement to be bound by the terms of this
Indenture, and each Subsidiary of the Company that becomes a Guarantor in
accordance with Section 4.16 and/or that executes a supplemental indenture in
which such Subsidiary agrees to become and be a Guarantor and to be bound by the
terms of this Indenture, jointly and severally, hereby unconditionally
guarantees to each Holder of a Note authenticated and delivered by the Trustee
and to the Trustee, irrespective of the validity or enforceability of this
Indenture, the Notes or the obligations of the Company under this Indenture or
the Notes, that: (i) the principal of and interest (and premium, if any) on the
Notes will be paid in full when due, whether at the maturity or interest payment
date, on any Change of Control Payment Date, by acceleration, call for
redemption, purchase or otherwise, and interest on the overdue principal and
interest, if any, of the Notes, if lawful, and all other obligations of the
Company to the Holders or the Trustee under this Indenture or the Notes will be
promptly paid in full or performed, all in accordance with the terms of this
Indenture and the Notes, and (ii) in case of any extension of time of payment or
renewal of any Notes or any of such other obligations, they will be paid in full
when due or performed in accordance with the terms of the extension or renewal,
whether at maturity, on any Change of Control Payment Date, by acceleration,
call for redemption, purchase or otherwise (such guarantees being the
"Guarantee"). Each Guarantor acknowledges and agrees with and for the benefit of
the Holders of the Notes that the Guarantee of such Guarantor shall be secured
by a perfected security interests in substantially all of the assets of the
Guarantor (except Inventory and Receivables), subject, however, to the rights of
the holders of Permitted Liens encumbering such assets, and provided, however,
that no Guarantor shall be obligated to grant any such security interest in any
asset encumbered by a Permitted Lien if the granting of such security interest
would constitute a default under or with respect to such Permitted Lien. The
Guarantee is a guarantee of payment and not of collection.

        Failing payment when due of any amount so guaranteed for whatever
reason, the Guarantors shall be jointly and severally obligated to pay the same
whether or not the failure to so pay is or becomes an Event of Default.

        (b) Each Guarantor agrees that (i) its obligations with regard to this
Guarantee shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to
enforce the same, any delays in obtaining or realizing upon (or failures to
obtain or realize upon) collateral, the recovery of any judgment against the
Company, any action to enforce the same or any other circumstances that might
otherwise constitute a legal or equitable discharge or defense of a guarantor,
and (ii) this Guarantee will not be discharged except by complete performance of
the obligations contained in the Notes and this Indenture. Each of the
Guarantors hereby waives diligence, presentment, demand of payment, filing of
claims with a court in the event of insolvency or bankruptcy of the Company, any
right to require a proceeding first against the Company or right to require the
prior disposition of the assets of the Company to meet its obligations, protest,
notice and all demands whatsoever and covenants that




                                       69
<PAGE>   77


this Guarantee will not be discharged except by complete performance of the
obligations contained in the Notes and this Indenture.

        (c) If any Holder or the Trustee is required by any court or otherwise
to return to either the Company or any Guarantor, or to any Custodian, trustee,
or similar official acting in relation to either the Company or any Guarantor,
any amount paid by either the Company or any of the Guarantors to the Trustee or
such Holder, this Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. Each of the Guarantors agrees that it will
not be entitled to any right of subrogation in relation to the Holders in
respect of any obligations guaranteed hereby until all of such obligations are
paid in full.

        (d) Each of the Guarantors agrees that (i) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Section 6.2 for
the purposes of the Guarantee, notwithstanding any stay, injunction or other
prohibition preventing such acceleration as to the Company of any of the
obligations guaranteed by the Guarantee, and (ii) in the event of any
declaration of acceleration of those obligations as provided in Section 6.2,
those obligations (regardless of whether due and payable) will forthwith become
due and payable by each of the Guarantors for the purpose of the Guarantee.

        Section 12.2 Execution and Delivery of Guarantee. To evidence the
Guarantee and its obligations thereunder as set forth in Section 12.1, each of
the Guarantors agrees that a notation of such Guarantee substantially in the
form annexed hereto as Exhibit B shall be endorsed on each Note authenticated
and delivered by the Trustee, and that this Indenture (or a supplement hereto)
shall be executed on behalf of such Guarantor by two Officers or an Officer and
an Assistant Secretary of such Guarantor.

        Each of the Guarantors agrees that the Guarantee and its obligations
thereunder as set forth in Section 12.1 shall remain in full force and effect
and apply to all the Notes notwithstanding any failure to endorse on each Note a
notation of such Guarantee.

        If an Officer whose facsimile signature is on a Note no longer holds
that office at the time the Trustee authenticates the Note on which the
Guarantee is endorsed, the Guarantee shall be valid nevertheless.

        The delivery of any Note by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of the Guarantee set forth in
this Indenture on behalf of the Guarantors.

        Section 12.3 Limitation of Guarantor's Liability. Each Guarantor and,
by its acceptance hereof, each Holder hereby confirms that it is the intention
of all such parties that the guarantee by such Guarantor pursuant to the
Guarantee not constitute a fraudulent transfer or conveyance for purposes of any
federal or state law. To effectuate the foregoing intention, the Holders and
each Guarantor hereby irrevocably agree that the obligations of each Guarantor
under the Guarantee shall be limited to the maximum amount as will, after giving
effect to all other contingent and fixed liabilities of such Guarantor and after
giving effect to any collections from or payments made by or on behalf of any
other Guarantor in respect of the obligations of such other Guarantor under its
Guarantee or pursuant to Section 12.4, result in the obligations of such
Guarantor under the Guarantee not constituting a fraudulent conveyance or
fraudulent transfer under federal or state law. This Section 12.3 is for the
benefit of the creditors of each Guarantor. The provisions of this Section 12.3
shall survive until the Notes have been fully paid or deemed to have been fully
paid within the meaning of this Indenture.




                                       70
<PAGE>   78


        Section 12.4 Contribution. In order to provide for just and equitable
contribution among the Guarantors, the Guarantors agree, inter se, that in the
event any payment or distribution is made by any Guarantor (a "Funding
Guarantor") under the Guarantee, such Funding Guarantor shall be entitled to a
contribution from each other Guarantor in a pro rata amount based on the
Adjusted Net Assets of each Guarantor (including the Funding Guarantor) for all
payments, damages and expenses incurred by that Funding Guarantor in discharging
the Company's obligations with respect to the Notes or any other Guarantor's
obligations with respect to the Guarantee.

        Section 12.5 Rights Under the Guarantee.

        (a) No payment by any Guarantor pursuant to the provisions hereof to the
Trustee shall entitle such Guarantor to any payment out of any Collateral held
by the Trustee under the Indenture or any Security Documents.

        (b) Each of the Guarantors waives notice of the issuance, sale and
purchase of the Notes and notice from the Trustee or the Holders from time to
time of any of the Notes of their acceptance and reliance on this Guarantee.

        (c) Notwithstanding any payment or payments made by the Guarantors by
reason of the Guarantee, the Guarantors shall not be subrogated to any rights of
the Trustee or any Holder of the Notes against the Company until all the Notes
shall have been fully paid or deemed to have been fully paid within the meaning
of this Indenture. Any payment made by the Guarantors by reason of this
Guarantee shall be in all respects subordinated to the full and complete payment
or discharge under the Indenture of all obligations guaranteed hereby, and no
payment by the Guarantors by reason of this Guarantee shall give rise to any
claim of the Guarantors against the Trustee or any Holder. Unless and until the
Notes shall have been fully paid or deemed to have been fully paid within the
meaning of the Indenture, neither the Guarantors nor any of them will assign or
otherwise transfer any such claim against the Company to any other Person.

        (d) No set-off, counterclaim, reduction or diminution of any obligation
or any defense of any kind or nature (other than performance by the Guarantor of
its obligation hereunder) which the Guarantor may have or assert against the
Trustee or any Holder of any Notes shall be available hereunder to the Guarantor
against the Trustee.

        (e) The Guarantor agrees to pay all costs, expense and fees, including
all reasonable attorneys' fees, which may be incurred by the Trustee in
enforcing or attempting to enforce the Guarantee or protecting the rights of the
Trustee or the Holders of Notes, if any, in accordance with this Indenture.

        Section 12.6 Severability. In case any provision of the Guarantee shall
be invalid, illegal or unenforceable, that portion of such provision that is not
invalid, illegal or unenforceable shall remain in effect, and the validity,
legality, and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

                           RIGHT TO REQUIRE REPURCHASE

        Section 13.1 Repurchase of Notes at Option of the Holder Upon Change of
Control.

        (a) In the event that a Change of Control occurs, each Holder shall have
the right, at such Holder's option, upon the terms and conditions of this
Article XIII, to require the Company to repurchase all or any part of such
Holder's Notes (provided, however, that the principal amount of such Notes at
maturity must be $1,000 or an integral multiple thereof) on a date that is no
later than 60 Business Days after the occurrence of a Change of Control (the
date on which the repurchase is effected being referred to herein as the "Change
of Control Payment Date"), at a cash purchase price (the "Change of Control
Purchase Price") equal to 101% of the principal amount thereof, plus accrued and
unpaid interest, if any, on and including the Change of Control Payment Date.

        (b) Within 20 Business Days after the Company knows, or reasonably
should know, of the occurrence of a Change of Control, the Company shall make an
irrevocable unconditional offer (a "Change of Control Offer") to the Holders to
purchase for U.S. Legal Tender all of the Notes pursuant to the offer described
in clause (c) of this Section 13.1 at the Change of Control Purchase Price.
Within five Business Days after each date upon which the Company knows, or
reasonably should know, of the occurrence of a Change of Control requiring the
Company to make a Change of Control Offer pursuant to this Section 13.1, the
Company shall so notify the Trustee.

        (c) Notice of a Change of Control Offer shall be sent, at least 20
Business Days prior to the Final Change of Control Put Date (as defined below),
by first class mail, by the Company to each Holder at its registered address,
with a copy to the Trustee. The notice to the Holders shall contain all
instructions and materials required by applicable law and shall contain or make
available to Holders other information material to such Holders' decision to
tender Notes pursuant to the Change of Control Offer. The notice, which shall
govern the terms of the Offer, shall state:

               (1) that a Change of Control has occurred and that such Holder
        has the right to require the Company to purchase such Holder's Notes at
        a purchase price in cash equal to 101% of the principal amount thereof
        plus accrued and unpaid interest, if any, to the date of purchase

2/3% in aggregate principal amount of the Notes then outstanding, and any
existing Default or Event of Default or compliance with any provision may be
waived with the consent of the Holders of at least 66 2/3% in aggregate
principal amount of the Notes then outstanding. Without notice to or consent of
any Holder, the parties thereto may amend or supplement the Indenture or the
Notes to, among other things, cure any ambiguity, defect or inconsistency
(provided, however, that such amendment or supplement does not adversely affect
the rights of any Holder of a Note).

12.      Restrictive Covenants.

         The Indenture imposes certain limitations on the ability of the Company
and its Subsidiaries to, among other things, Incur additional Debt or issue
Disqualified Capital Stock, make payments in respect of its Capital Stock, enter
into transactions with Affiliates, incur Liens, sell assets, change the nature
of its business, merge or consolidate with any other Person and sell, lease,
transfer or otherwise dispose of substantially all of its properties or assets.
The limitations are subject to a number of important qualifications and
exceptions. The Company must deliver a quarterly report to the Trustee on
compliance with such limitations.

13.      Change of Control.

         In the event there shall occur any Change of Control, each Holder of
Notes shall have the right, at such Holder's option but subject to the
limitations and conditions set forth in the Indenture, to require the Company to
purchase on the Change of Control Payment Date in the manner specified in the
Indenture, all or any part (in integral multiples of $1,000) of such Holder's
Notes at a Change of Control Purchase Price equal to 101% of the principal
amount thereof, together with accrued and unpaid interest, if any, on and
including the Change of Control Payment Date.

14.      Successors.

         When a successor assumes all the obligations of its predecessor under
the Notes and the Indenture, the predecessor will be released from those
obligations.

<PAGE>   89


15.      Defaults and Remedies.

         If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in aggregate combined principal amount of the Notes and
the Company's Senior Secured Discount Notes then outstanding may declare all the
Notes to be due and payable immediately in the manner and with the effect
provided in the Indenture. Holders of Notes may not enforce the Indenture or the
Notes except as provided in the Indenture. The Trustee may require indemnity
satisfactory to it before it enforces the Indenture or the Notes. Subject to
certain limitations, Holders of a majority in aggregate principal amount of the
Notes then outstanding may direct the Trustee in its exercise of any trust or
power. The Trustee may withhold from Holders of Notes notice of any continuing
Default or Event of Default (except a Default in payment of principal, premium,
if any, or interest, including a Default at any Maturity Date), if it determines
that withholding notice is in their interest.

16.      No Recourse Against Others.

         No stockholder, director, officer, employee or incorporator, as such,
past, present or future, of the Company or any of its Subsidiaries or any
successor corporation shall have any liability for any obligation of the Company
or such Subsidiary under the Notes 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 Note by accepting a Note waives and releases all such liability. The waiver
and release are part of the consideration for the issuance of the Notes.

17.      Authentication.

         This Note shall not be valid until the Trustee or authenticating agent
signs the certificate of authentication on the other side of this Note.

18.      Abbreviations and Defined Terms.

         Customary abbreviations may be used in the name of a Holder of a Note
or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by
the entireties), JT TEN (= joint tenants with right of survivorship and not as
tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors
Act). Capitalized terms used herein and not otherwise defined shall have the
meanings assigned to them in the Indenture.

19.      CUSIP Numbers.

         Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company will cause CUSIP numbers to be
printed on the Notes as a convenience to the Holders of the Notes. No
representation is made as to the accuracy of such numbers as printed on the
Notes and reliance may be placed only on the other identification numbers
printed hereon.
