Each notice for 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 and/or the original issue discount ceases to accrete on Notes called for redemption 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 (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. 49 56 Section 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 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, and upon satisfaction or waiver of any conditions precedent to the Company's obligation to effect such redemption contained in the related notice of redemption, interest on the Notes called for redemption will cease to accrue, and/or the original issue discount will cease to accrete on the Notes called for redemption, on and after the Redemption Date, regardless of whether such Notes are presented for payment. Section 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, and/or the original issue discount will cease to accrete on the Notes to be redeemed 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 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 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 on the Notes shall be considered paid on the date it is due if the Trustee or Paying Agent (other 50 57 than the Company or an Affiliate of the Company) holds for the benefit of the Holders, on or before 11:00 a.m. Houston, Texas time on that date, U.S. Legal Tender deposited and designated for and sufficient to pay the installment. 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 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 13.2. 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 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 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 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 16 Guarantee by Subsidiaries. If TARC or TransTexas or any of their respective 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 $1,000,000 in or to any Subsidiary of the Company that is not a Guarantor or an obligor on either the TransTexas Intercompany Loan or the TARC Intercompany Loan, other than TTXD or any Subsidiary of TTXD after the TTXD Spin-off, the Company shall (a) cause such transferee Subsidiary to (x) guarantee payment of the TransTexas Intercompany Loan, in the case of Subsidiaries of TransTexas, or the TARC Intercompany Loan in the case of Subsidiaries of TARC, by executing a Guarantee and (y) execute the appropriate security document, in substantially the form of the relevant Security Document attached hereto, necessary to grant a security interest in all of the assets of such 69 76 Subsidiary (other than Equipment, Inventory and Receivables) to secure such Guarantee and (b) deliver to the Trustee an Opinion of Counsel, in form reasonably satisfactory to the Trustee, that such Guarantee is a valid, binding and enforceable obligation of such Subsidiary, subject to customary exceptions for bankruptcy, fraudulent transfer and equitable principles. If TARC or TransTexas or any of their Subsidiaries shall subsequently sell or otherwise transfer all of the Capital Stock of such Subsidiary held by TARC, TransTexas or any of their Subsidiaries, the Guarantee required hereby shall be withdrawn or cancelled. In addition, if the TTXD Spin-off has occurred the Guarantee by TTXD or any of its Subsidiaries shall be withdrawn or cancelled. The liability of each Guarantor under its Guarantee will be limited to the amount of its Adjusted Net Assets. Each Guarantor that makes a payment under its Guarantee of the TARC Intercompany Loan or the TransTexas Intercompany Loan shall be entitled to assert a claim for reimbursement from each other Guarantor of the respective Intercompany Loan, in each case in an amount not to exceed the product of (x) the other Guarantor's Adjusted Net Assets times (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 same Intercompany Loan.

Upon any consolidation or merger, or any transfer of assets in accordance with Section 5.1, the Surviving Person formed by such consolidation or into which the Company, TARC or TransTexas, as the case may be, is merged or to which such transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company, TARC or TransTexas, as the case may be, under this Indenture with the same effect as if such Surviving Person had been named as the Company, TARC or TransTexas, as the case may be, herein. When a Surviving Person duly assumes all of the obligations of the Company pursuant hereto and pursuant to the Notes, the predecessor shall be released from such obligations. ARTICLE VI EVENTS OF DEFAULT AND REMEDIES Section 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): 77 84 (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 30 days;

(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 $25,000,000, or 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 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; (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 $25,000,000 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 78 85 final judgment which provides for payment over time, which shall so remain unstayed, unbonded or undischarged beyond any applicable payment date provided therein); (h) any of the Security Documents shall for any reason cease to be in full force and effect (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 Lien, rights, powers and privileges shall not have a material adverse effect on the Holders; (i) Independent Directors not constituting a majority of the Board of Directors of the Company for a period of 90 days in the aggregate in any twelve-month period; (j) if the Phase I Completion Date has not occurred by the Required Phase I Completion Date; or (k) if the Phase II Completion Date has not occurred by January 31, 2000. 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, including a default in the payment of the Excess Cash Offer Price, Additional Interest Excess Cash Offer Price or Change of Control Purchase Price as required by this Indenture, 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, 4.14, 4.21, 4.24 or 5.1, which Defaults shall be Events of Default without the notice specified in this paragraph or 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) seven) 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 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 (f) relating to the Company or its Subsidiaries) occurs and is continuing, then, and in every such case, unless the principal of all of the Notes 79 86 shall have already become due and payable, either the Trustee or the Holders of not less than 25% in aggregate Value 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 (or the Change of Control Purchase Price if the Event of Default includes failure to pay the Change of Control Purchase Price), 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 its Subsidiaries 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 a majority in aggregate Value 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, (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, including, if applicable, any Event of Default relating to the covenants contained in Section 11.1. 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) 66 2/3% in aggregate Value of the Notes or (y) the affected Holder of each of the outstanding Notes, unless (x) 66 2/3% in aggregate Value 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 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 (1) or (2) 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 80 87 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. 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 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. 81 88 Section 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 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 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 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 82 89 enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders. Section 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 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 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 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 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 11 Control by Holders. The Holder or Holders of a majority in aggregate Value 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 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 12 Waiver of Past Default. Subject to Section 6.8, the Holder or Holders of not less than a majority in aggregate Value 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, or (b) 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 66 2/3% in aggregate Value of the Notes at the time outstanding, as the case may be; provided that such a default may be waived by 83 90 the consent of Holders of each outstanding Note affected or 66 2/3% in aggregate value 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 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 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 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 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. 84 91 (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.

(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 paragraphs (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 12.2. Section 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.

(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 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 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 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 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 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 Section 313(a). The Trustee also shall comply with TIA Sections 313(b) and 313(c). 86 93 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 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 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 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 (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 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; 87 94 (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 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. 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.

ARTICLE IX AMENDMENTS, SUPPLEMENTS AND WAIVERS Section 1 Supplemental Indentures Without Consent of Holders.

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 supplemental indenture. After an amendment, supplement or waiver under this Section 9.2 or 9.4 becomes effective, it shall bind each Holder. 93 100 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, or to all Holders, consideration for such Holder's consent to such amendment, supplement or waiver. Section 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 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 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 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 6 Trustee to Sign Amendments, Etc. The Trustee shall execute any amendment, supplement or waiver authorized pursuant to this Article IX, provided that the Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the Trustee's own rights, duties or immunities under this Indenture. The Trustee at the expense of the 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 or waiver authorized pursuant to this Article IX is authorized or permitted by this Indenture. 94 101 ARTICLE X MEETINGS OF NOTEHOLDERS Section 1 Purposes for Which Meetings May Be Called.
