RECITALS OF THE PARENT AND THE SUBSIDIARY ISSUER The Parent has heretofore executed and delivered to the Trustee an Indenture, dated as of September 16, 2003 relating to its subordinated debt securities (the "Original Parent Indenture"), providing for the issuance from time to time of one or more series of the Parents' subordinated debt Securities. The Subsidiary Issuer has heretofore executed and delivered to the Trustee an Indenture, dated as of September 16, 2003 relating to its subordinated debt securities (the "Original Subsidiary Issuer Indenture" and, together with the Original Parent Indenture, the "Original Indentures," and, as each shall be amended and supplemented by this First Supplemental Indenture, the "Indenture"), providing for the issuance from time to time of one or more series of the Subsidiary Issuer's subordinated debt Securities. Section 901(7) of each of the Original Indentures provides that the Parent or the Subsidiary Issuer, as applicable, and the Trustee may from time to time enter into one or more indentures supplemental thereto to establish the form or terms of Securities of a new series. Sections 901(2) and 901(3) of each of the Original Indentures permit the execution of supplemental indentures without the consent of any Holders to add to the covenants of the Parent or the Subsidiary Issuer, as applicable, for the benefit of, and to add any additional Events of Default with respect to, all or any series of Securities. Section 901(5) of each of the Original Indentures permits the execution of supplemental indentures without the consent of any Holders to add to, change or eliminate any of the provisions of the Indenture with respect to all or any series of Securities, provided that, among other things, such addition, change or elimination does not apply to any outstanding Security of any series created prior to the execution of such supplemental indenture. Section 301 of each of the Original Indentures provides that the Company may enter into supplemental indentures to establish the form, terms and provisions of a series of Securities issued pursuant to the Indenture. Sections 301(19) and 301(20) of each of the Original Indentures permit such supplemental indentures to add or to change the covenants and Events of Default that apply to Securities of the series to be issued. Section 301(22) of each of the Original Indentures permits such supplemental indenture to determine whether the Securities of the series to be issued will be issued together with other securities as units. 1 The Parent has duly authorized the issuance of its 7.25% Senior Subordinated Notes due September 15, 2013 (the "Parent Notes"), and to provide therefor the Parent has duly authorized the execution and delivery of this Indenture. The Subsidiary Issuer has duly authorized the issuance of its 7.25% Senior Subordinated Notes due September 15, 2013 (the "Subsidiary Notes" and, together with the Parent Notes, the "Notes"), and to provide therefor the Subsidiary Issuer has duly authorized the execution and delivery of this Indenture. The Parent has duly authorized the unconditional guarantee (the "Parent Guarantee") of the Subsidiary Issuer's obligations under the Subsidiary Notes and all the obligations of the Subsidiary issuer as set forth in this Indenture. The Parent and the Subsidiary Issuer have duly authorized the creation of units (the "Units"), each Unit consisting, subject to the Section 802, of $512 aggregate principal amount of Parent Notes and $488 aggregate principal amount of Subsidiary Notes. This Indenture is subject to the provisions of the Trust Indenture Act of 1939, as amended, that are required to be part of this Indenture and shall, to the extent applicable, be governed by such provisions. All things necessary have been done to make the Parent Notes, the Subsidiary Notes, the Parent Guarantee and the Units, each when duly issued, executed and delivered by the Parent and/or the Subsidiary Issuer, as the case may be, and authenticated as described herein, the valid obligations of the Parent and/or the Subsidiary Issuer, as the case may be, and to make this Indenture a valid agreement of the Parent and the Subsidiary Issuer, in accordance with its terms. Each party agrees as follows for the benefit of the other parties and for the equal and ratable benefit of the Holders of Units. ---------------------------------- ARTICLE I NOTES AND UNITS SECTION 1.1.

The Parent Notes, the Subsidiary Notes and any Additional Units shall be considered collectively as a single class for all purposes of this Indenture. Holders of the Parent Notes, the Subsidiary Notes and Additional Parent Notes and Additional Subsidiary Notes will vote and consent together on all matters to which such Holders are entitled to vote or consent as one class, and none of the Holders of the Parent Notes, the Subsidiary Notes or Additional Parent Notes and Additional Subsidiary Notes shall have the right to vote or consent as a separate class on any matter to which such Holders are entitled to vote or consent.

The Units will initially be issued in the form of a fully registered global security, which will be deposited with The Depository Trust Company ("DTC"). The principal of, premium, if any, and interest on the Notes (including Additional Amounts, if any, on the Subsidiary Notes) will be payable at the office or agency of the Parent and the Subsidiary Issuer maintained for such purpose in The City of New York, New York, or 3 at such other office or agency of the Parent and the Subsidiary Issuer as may be maintained for such purpose pursuant to Section 1.3; provided, however, that, at the option of the Parent or the Subsidiary Issuer, as the case may be, interest may be paid by check mailed to addresses of the Persons entitled thereto as such addresses shall appear on the Register. Payments in respect of the Parent Notes and the Subsidiary Notes (including principal of, premium, if any, and interest on the Notes (including Additional Amounts, if any, on the Subsidiary Notes)) will be made by wire transfer of immediately available funds to the accounts specified by DTC.

OR SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF 4 DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN." (E) Book-Entry Provisions. (1) This Section 1.1(e) shall apply only to the Global Unit deposited with the Trustee, as custodian for DTC. (2) The Global Unit initially shall (x) be registered in the name of DTC for the Global Unit or the nominee of DTC, (y) be delivered to the Trustee as custodian for DTC and (z) bear legends as set forth in Section 1.1(d). (3) Members of, or participants in, DTC ("Agent Members") shall have no rights under this Indenture with respect to the Global Unit held on their behalf by DTC or by the Trustee as the custodian of DTC or under the Global Unit, and DTC may be treated by the Parent, the Subsidiary Issuer or the Trustee and any agent of the Parent, the Subsidiary Issuer or the Trustee as the absolute owner of the Global Unit for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Parent, the Subsidiary Issuer or the Trustee or any agent of the Parent, the Subsidiary Issuer or the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or impair, as between DTC and its Agent Members, the operation of customary practices of DTC governing the exercise of the rights of a Holder of a beneficial interest in the Global Unit. (4) In connection with any transfer of a portion of the beneficial interest in the Global Unit pursuant to subsection (d) of this Section to beneficial owners who are required to hold Definitive Securities, the Registrar shall reflect on its books and records the date and a decrease in the principal amount of the Global Unit in an amount equal to the principal amount of the beneficial interest in the Global Unit to be transferred, and the Parent and the Subsidiary Issuer shall execute, and the Trustee shall authenticate and deliver, one or more Definitive Securities of like tenor and amount. (5) In connection with the transfer of the Global Unit to beneficial owners pursuant to subsection (d) of this Section, the Global Unit shall be deemed to be surrendered to the Trustee for cancellation, and the Parent and the Subsidiary Issuer shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by DTC in exchange for its beneficial interest in the Global Unit, an equal aggregate principal amount of Definitive Securities of authorized denominations. 5 (6) The registered Holder of the Global Unit may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or under the Notes or the Units. (F) Definitive Securities. (1) Except as provided below, owners of beneficial interests in the Global Unit will not be entitled to receive Definitive Securities. If required to do so pursuant to any applicable law or regulation, beneficial owners may obtain Definitive Securities in exchange for their beneficial interests in the Global Unit upon written request in accordance with DTC's and the Registrar's procedures. In addition, Definitive Securities shall be transferred to all beneficial owners in exchange for their beneficial interests in the Global Unit if (a) the Parent and the Subsidiary Issuer notify the Trustee in writing that DTC is unwilling or unable to continue as Depositary for the Global Unit or DTC ceases to be a clearing agency registered under the Exchange Act, at a time when DTC is required to be so registered in order to act as Depositary, and in each case a successor Depositary is not appointed by the Parent and the Subsidiary Issuer within 90 days of such notice or cessation, (b) each of the Parent and the Subsidiary Issuer executes and delivers to the Trustee and the Registrar an Officers' Certificate stating that the Global Unit shall be so exchangeable or (c) an Event of Default has occurred and is continuing and the Registrar has received a request from DTC that the Global Unit be so exchanged. Upon the occurrence of any of the preceding events in (a), (b) or (c) above, Definitive Securities shall be issued in such names as DTC shall instruct the Trustee. (2) Any Definitive Securities delivered in exchange for interest in the Global Unit pursuant to Section 1.1(e)(4) or (5) shall bear the applicable legend, as set forth in Section 1.1(d). (3) In connection with the exchange of a portion of a Definitive Security for a beneficial interest in the Global Unit, the Trustee shall cancel such Definitive Security, and the Parent and the Subsidiary Issuer shall execute, and the Trustee shall authenticate and deliver, to the transferring Holder a new Definitive Security representing the principal amount not so transferred. SECTION 1.2. EXECUTION AND AUTHENTICATION The Parent Notes shall be signed by one Officer of the Parent by either manual or facsimile signature. The Subsidiary Notes shall be signed by one Officer of the Subsidiary Issuer by either manual or facsimile signature. The Units shall be signed by one Officer of the Parent and one Officer of the Subsidiary Issuer by either manual or facsimile signature. If an Officer whose signature is on a Note or a Unit no longer holds that office at the time the Trustee 6 authenticates the Note or the Unit, as the case may be, such Note or Unit shall be valid nevertheless. A Note or Unit shall not be valid until an authorized signatory of the Trustee manually authenticates the Note or Unit, as the case may be. The signature of the Trustee on a Note or Unit shall be conclusive evidence that such Note or Unit has been duly and validly authenticated and issued under this Indenture. A Note or Unit shall be dated the date of its authentication. The Trustee may appoint an agent (the "Authenticating Agent") reasonably acceptable to the Parent and the Subsidiary Issuer to authenticate the Notes and the Units. Unless limited by the terms of such appointment, any such Authenticating Agent may authenticate the Notes and the Units whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by the Authenticating Agent. An Authenticating Agent has the same rights as a Paying Agent to deal with Holders or an Affiliate of the Parent and the Subsidiary Issuer. SECTION 1.3. REGISTRAR AND PAYING AGENT The Parent and the Subsidiary Issuer shall maintain an office or agency where Notes and Units may be presented for registration of transfer or for exchange (the "Registrar") and an office or agency where Notes may be presented for payment (the "Paying Agent"). The Parent and the Subsidiary Issuer shall cause each of the Registrar and the Paying Agent to maintain an office or agency in New York, New York. The Registrar shall keep a register of the Notes and Units and of their transfer and exchange (the "Register"). The Parent and the Subsidiary Issuer may have one or more co-registrars and one or more additional paying agents. The term "Paying Agent" includes any additional paying agent. The Parent and the Subsidiary Issuer shall enter into an appropriate agency agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Parent and the Subsidiary Issuer shall notify the Trustee of the name and address of each such agent. If the Parent and the Subsidiary Issuer fail to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 607. The Parent or the Subsidiary Issuer may act as Paying Agent, Registrar, co-registrar or transfer agent. The Parent and the Subsidiary Issuer initially appoints the Trustee as Registrar and Paying Agent. SECTION 1.4. PAYING AGENT TO HOLD MONEY IN TRUST By no later than 10:00 a.m. (New York City time) on the date on which any principal of or interest on any Note is due and payable, the Parent and the Subsidiary Issuer shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such principal or interest when due. The Parent and the Subsidiary Issuer shall require each Paying Agent (other than the Trustee) to agree in writing that such Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by such Paying Agent for the payment of principal of or interest on the Notes and shall notify the Trustee in writing of any default by any of the Parent 7 or the Subsidiary Issuer in making any such payment. If either the Parent or the Subsidiary Issuer acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Parent or the Subsidiary Issuer at any time may require a Paying Agent (other than the Trustee) to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon complying with this Section, the Paying Agent (if other than the Parent or the Subsidiary Issuer, as the case may be) shall have no further liability for the money delivered to the Trustee. Upon any bankruptcy, reorganization or similar proceeding with respect to the Parent or the Subsidiary Issuer, the Trustee shall serve as Paying Agent for the Notes. SECTION 1.5. HOLDER 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 of Notes and Units. If the Trustee is not the Registrar, or to the extent otherwise required under the TIA, the Parent and the Subsidiary Issuer shall furnish to the Trustee, in writing at least five Business Days before 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 may reasonably require of the names and addresses of Holders. SECTION 1.6. MUTILATED, DESTROYED, LOST OR STOLEN NOTES AND UNITS If a mutilated Note or Unit is surrendered to the Registrar or if the Holder of a Note or Unit claims that such Note or Unit has been lost, destroyed or wrongfully taken, the Parent and/or the Subsidiary Issuer, as the case may be, shall issue and the Trustee shall authenticate a replacement Note or Unit if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the Trustee, the Parent and/or the Subsidiary Issuer, as the case may be, such Holder shall furnish an indemnity sufficient in the judgment of the Trustee, the Parent and/or the Subsidiary Issuer, as the case may be, to protect the Parent and/or the Subsidiary Issuer, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss which any of them may suffer if a Note or Unit is replaced, and, in the absence of notice to the Parent and/or the Subsidiary Issuer, as the case may be, and the Trustee that such Note or Unit has been acquired by a bona fide purchaser, the Parent and/or the Subsidiary Issuer, as the case may be, shall execute by either manual or facsimile signature (and the Trustee shall authenticate and make available for delivery), in exchange for any such mutilated Note or Unit or in lieu of any such destroyed, lost or stolen Note or Unit, a new Note or Unit of like tenor and principal amount, bearing a number not contemporaneously outstanding. In case any such mutilated, destroyed, lost or stolen Note or Unit has become or is about to become due and payable, the Parent and/or the Subsidiary Issuer, as the case may be, in its discretion may, instead of issuing a new Note or Unit, pay such Note or Unit. Upon the issuance of any new Note or Unit under this Section, the Parent and/or the Subsidiary Issuer, as the case may be, may require the payment by the Holder thereof of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) in connection therewith. 8 Every new Note or Unit issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Note or Unit shall constitute an original additional contractual obligation of the Parent and/or the Subsidiary Issuer, as the case may be, and any other obligor upon the Note or Unit, whether or not the mutilated, destroyed, lost or stolen Note or Unit shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Notes and Units duly issued hereunder. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes or Units. SECTION 1.7. OUTSTANDING NOTES AND UNITS Notes and Units outstanding at any time are all Notes and Units authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section 1.7 as not outstanding. A Note or Unit, as the case may be, ceases to be outstanding in the event the Parent or the Subsidiary Issuer or a subsidiary of the Parent or the Subsidiary Issuer holds such Note or Unit, provided, however, that (i) for purposes of determining which are outstanding for consent or voting purposes hereunder, Notes and Units shall cease to be outstanding in the event the Parent or the Subsidiary Issuer or an Affiliate of the Parent or the Subsidiary Issuer holds such Note or Unit and (ii) in determining whether the Trustee shall be protected in making a determination whether the Holders of the requisite principal amount of outstanding Notes or Units are present at a meeting of Holders of Notes or Units for quorum purposes or have consented to or voted in favor of any request, demand, authorization, direction, notice, consent, waiver, amendment or modification hereunder, or relying upon any such quorum, consent or vote, only Notes or Units which a Trust Officer of the Trustee actually knows to be held by the Parent or the Subsidiary Issuer or an Affiliate of the Parent or the Subsidiary Issuer shall not be considered outstanding. If a Note or Unit is replaced pursuant to Section 1.6, it ceases to be outstanding unless the Trustee, the Parent and the Subsidiary Issuer receive proof satisfactory to them that the replaced Note or Unit, as the case may be, is held by a bona fide purchaser. If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a Redemption Date or Stated Maturity money sufficient to pay all principal and interest payable on that date with respect to the Notes or Units (or portions thereof) to be redeemed or maturing, as the case may be, and the Paying Agent is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture, then on and after that date such Notes or Units (or portions thereof) cease to be outstanding and interest on them ceases to accrue. SECTION 1.8. TEMPORARY NOTES AND UNITS Until Definitive Securities are ready for delivery, the Parent and the Subsidiary Issuer may prepare and the Trustee shall authenticate temporary Parent Notes, temporary Subsidiary Notes and temporary Units (together, the "Temporary Securities"). Temporary Securities shall be substantially in the form of the Definitive Securities but may have variations that the Parent and the Subsidiary Issuer consider appropriate for Temporary Securities. Without unreasonable 9 delay, the Parent and the Subsidiary Issuer shall prepare and the Trustee shall authenticate Definitive Securities. After the preparation of Definitive Securities, the Temporary Securities shall be exchangeable for Definitive Securities upon surrender of the Temporary Securities at any office or agency maintained by the Parent and the Subsidiary Issuer for that purpose and such exchange shall be without charge to the Holder. Upon surrender for cancellation of any one or more Temporary Securities, the Parent and the Subsidiary Issuer shall execute, and the Trustee shall authenticate and make available for delivery in exchange therefor, one or more Definitive Securities representing an equal principal amount of Parent Notes, Subsidiary Notes and Units. Until so exchanged, the Holder of Temporary Securities shall in all respects be entitled to the same benefits under this Indenture as a Holder of Definitive Securities. SECTION 1.9. CANCELLATION The Parent and the Subsidiary Issuer at any time may deliver Notes or Units to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes or Units surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and return to the Parent and/or the Subsidiary Issuer, as the case may be, all Note and Units surrendered for registration of transfer, exchange, payment or cancellation. The Parent and the Subsidiary Issuer may not issue new Notes or Units to replace Notes or Units it has paid or delivered to the Trustee for cancellation for any reason other than in connection with a transfer or exchange. SECTION 1.10. PAYMENT OF INTEREST; DEFAULTED INTEREST Interest on the Notes 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 the Notes are registered at the close of business on the regular record date for such interest at the office or agency of the Parent or the Subsidiary Issuer, as the case may be, maintained for such purpose pursuant to Section 1.3. Any interest on any Parent Note or Subsidiary Note, which is payable, but is not paid when the same becomes due and payable and such nonpayment continues for a period of 30 days shall forthwith cease to be payable to the Holder on the regular record date by virtue of having been such Holder, and such defaulted interest and (to the extent lawful) interest on such defaulted interest at the rate borne by the Notes (such defaulted interest and interest thereon herein collectively called "Defaulted Interest") shall be paid by the Parent or the Subsidiary Issuer, as the case may be, at its election in each case, as provided in clause (a) or (b) below: (A) The Parent or the Subsidiary Issuer, as the case may be, may elect to make payment of any Defaulted Interest to the Persons in whose names the Note is registered at the close of business on a Special Record Date (as defined below) for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Parent or the Subsidiary Issuer, as the case may be, shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date (not less than 30 days after such notice) of the proposed payment (the "Special Interest Payment Date"), and at the same time the Parent or the Subsidiary Issuer, as the case may be, 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 10 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 in this clause provided. Thereupon the Trustee shall fix a record date (the "Special Record Date") for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the Special Interest Payment Date 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 Parent or the Subsidiary Issuer, as the case may be, of such Special Record Date, and in the name and at the expense of the Parent or the Subsidiary Issuer, as the case may be, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be given in the manner provided for in Section 12.2, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having been so given, such Defaulted Interest shall be paid on the Special Interest Payment Date to the Persons in whose names the Units are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b). (B) The Parent or the Subsidiary Issuer, as the case may be, may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Units may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Parent or the Subsidiary Issuer, as the case may be, to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. Subject to the foregoing provisions of this Section, each Note delivered under this Indenture upon registration of, 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 1.11. COMPUTATION OF INTEREST Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. Solely for purposes of the Interest Act (Canada), the yearly rate of interest to which interest calculated for a period of less than one year on the basis of a year of 360 days consisting of 12 30-day periods is equivalent is such rate of interest multiplied by a fraction of which (i) the numerator is the product of (A) the actual number of days in the year commencing on the first day of such period, multiplied by (B) the sum of (y) the product of 30 multiplied by the number of complete months elapsed in such period and (z) the actual number of days elapsed in any incomplete month in such period; and (ii) the denominator is the product of (a) 360 multiplied by (b) the actual number of days in such period. The Trustee shall have no obligation to calculate interest under the Interest Act (Canada). SECTION 1.12. CUSIP AND ISIN NUMBERS The Parent and the Subsidiary Issuer in issuing the Notes and Units may use "CUSIP" and "ISIN" numbers (if then generally in use) and, if so, the Trustee shall use "CUSIP" and "ISIN" numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Units or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes and Units, and any such redemption shall not be affected by any defect in or omission of such CUSIP or ISIN numbers. 11 The Parent and the Subsidiary Issuer shall promptly notify the Trustee of any change in the CUSIP and ISIN numbers. SECTION 1.13. REDEMPTION AND REPURCHASE (A) There shall be no sinking fund for the retirement of the Parent Notes or the Subsidiary Notes or other mandatory redemption obligation. (B) The Parent and Subsidiary Issuer, at their joint option, may redeem the Units in accordance with the provisions of the Parent Notes, the Subsidiary Notes and the Indenture, including, without limitation, Article Eleven. (C) The Parent and Subsidiary Issuer, at the option of the Holders thereof, shall jointly repurchase the Units in accordance with the provisions of the Parent Notes, the Subsidiary Notes and the Indenture, including, without limitation, Sections 1009 and 1017. SECTION 1.14. CONVERSION The Units, the Parent Notes and the Subsidiary Notes shall not be convertible into any other securities. SECTION 1.15. MATURITY The Stated Maturity of the Parent Notes and the Subsidiary Notes shall be September 15, 2013. SECTION 1.16. PARENT SECURITIES The Subsidiary Notes shall be guaranteed by the Parent in accordance with the provisions of Article Thirteen and Exhibit C hereto. SECTION 1.17. OTHER TERMS OF PARENT NOTES, SUBSIDIARY NOTES AND UNITS Without limiting the foregoing provisions of this Article I, the terms of the Parent Notes, the Subsidiary Notes and the Units shall be as provided in the forms of the Parent Notes, the Subsidiary Notes and the Units as set forth in Exhibit A, Exhibit B, and Exhibit C respectively, hereto and as provided in the Indenture.

or (b) has repaid, repurchased, defeased or otherwise discharged any Indebtedness since the beginning of the period that is no longer outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio involves a discharge of Indebtedness (in each case other than Indebtedness Incurred under any revolving credit facility unless such Indebtedness has been permanently repaid and the related commitment terminated), Consolidated 20 EBITDA and Consolidated Interest Expense for such period will be calculated after giving effect on a pro forma basis to such discharge of such Indebtedness, including with the proceeds of such new Indebtedness, as if such discharge had occurred on the first day of such period; (2) if since the beginning of such period the Parent or any Restricted Subsidiary will have made any Asset Disposition or disposed of any company, division, operating unit, segment, business, group of related assets or line of business or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is such an Asset Disposition: (a) the Consolidated EBITDA for such period will be reduced by an amount equal to the Consolidated EBITDA (if positive) directly attributable to the assets which are the subject of such Asset Disposition for such period or increased by an amount equal to the Consolidated EBITDA (if negative) directly attributable thereto for such period; and (b) Consolidated Interest Expense for such period will be reduced by an amount equal to the Consolidated Interest Expense directly attributable to any Indebtedness of the Parent or any Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with respect to the Parent and its continuing Restricted Subsidiaries in connection with such Asset Disposition for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest Expense for such period directly attributable to the Indebtedness of such Restricted Subsidiary to the extent the Parent and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale); (3) if since the beginning of such period the Parent or any Restricted Subsidiary (by merger or otherwise) will have made an Investment in any Restricted Subsidiary (or any Person which becomes a Restricted Subsidiary or is merged with or into the Parent) or an acquisition of assets, including any acquisition of assets occurring in connection with a transaction causing a calculation to be made hereunder, which constitutes all or substantially all of a company, division, operating unit, segment, business, group of related assets or line of business, Consolidated EBITDA and Consolidated Interest Expense for such period will be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition occurred on the first day of such period; and (4) if since the beginning of such period any Person (that subsequently became a Restricted Subsidiary or was merged with or into the Parent or any Restricted Subsidiary since the beginning of such period) will have Incurred any Indebtedness or discharged any Indebtedness, made any Asset Disposition or any Investment or acquisition of assets that would have required an adjustment pursuant to clause (2) or (3) above if made by the Parent or a Restricted Subsidiary during such period, Consolidated EBITDA and Consolidated Interest 21 Expense for such period will be calculated after giving pro forma effect thereto as if such Asset Disposition or Investment or acquisition of assets occurred on the first day of such period. For purposes of this definition, whenever pro forma effect is to be given to any calculation under this definition, the pro forma calculations will be determined in good faith by a responsible financial or accounting officer of the Parent (including pro forma expense and cost reductions calculated on a basis consistent with Regulation S-X under the Securities Act). If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest expense on such Indebtedness will be calculated as if the rate in effect on the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness if such Interest Rate Agreement has a remaining term in excess of 12 months). If any Indebtedness that is being given pro forma effect bears an interest rate at the option of the Parent, the interest rate shall be calculated by applying such optional rate chosen by the Parent. "Consolidated EBITDA" for any period means, without duplication, the Consolidated Net Income for such period, plus the following to the extent deducted in calculating such Consolidated Net Income: (1) Consolidated Interest Expense; (2) Consolidated Income Taxes; (3) consolidated depletion and depreciation expense; (4) consolidated exploration expense; (5) consolidated amortization expense or impairment charges recorded in connection with the application of Financial Accounting Standard No. 142 "Goodwill and Other Intangible Assets;" (6) other non-cash charges reducing Consolidated Net Income (excluding any such non-cash charge to the extent it represents an accrual of or reserve for cash charges in any future period or amortization of a prepaid cash expense that was paid in a prior period not included in the calculation); and less, to the extent included in calculating such Consolidated Net Income and in excess of any costs or expenses attributable thereto and deducted in calculating such Consolidated Net Income, the sum of (x) the amount of deferred revenues that are amortized during such period and are attributable to reserves that are subject to volumetric Production Payments, and (y) amounts recorded in accordance with GAAP as repayments of principal and interest pursuant to dollar-denominated Production Payments. Notwithstanding the preceding sentence, clauses (2) through (5) relating to amounts of a Restricted Subsidiary of a Person will be added to Consolidated Net Income to compute Consolidated EBITDA of such Person only to the extent (and in the same proportion) that the net income (loss) of such Restricted Subsidiary was included in calculating the Consolidated Net Income of such Person and, to the extent the amounts set forth in clauses (2) through (5) are in excess of those necessary to offset a net loss of such Restricted Subsidiary 22 or if such Restricted Subsidiary has net income for such period included in Consolidated Net Income, only if a corresponding amount would be permitted at the date of determination to be dividended to the Parent by such Restricted Subsidiary without prior approval (that has not been obtained), pursuant to the terms of its charter and all agreements, instruments, judgments, decrees, orders, statutes, rules and governmental regulations applicable to that Restricted Subsidiary or its stockholders. "Consolidated Income Taxes" means, with respect to any Person for any period, taxes imposed upon such Person or other payments required to be made by such Person by any governmental authority which taxes or other payments are calculated by reference to the income or profits of such Person or such Person and its Restricted Subsidiaries (to the extent such income or profits were included in computing Consolidated Net Income for such period), regardless of whether such taxes or payments are required to be remitted to any governmental authority.

No Restricted Subsidiary may Incur any Indebtedness if the proceeds are used to refinance Indebtedness of the Parent.

The amount of any Indebtedness outstanding as of any date shall be (i) the accreted value thereof in the case of any Indebtedness issued with original issue discount and (ii) the principal amount or liquidation preference thereof, together with any interest thereon that is more than 30 days past due, in the case of any other Indebtedness. (j) In addition, the Parent will not permit any of its Unrestricted Subsidiaries to Incur any Indebtedness or issue any shares of Disqualified Stock, other than Non-Recourse Debt. If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, the Parent will require such Subsidiary to provide a Subsidiary Guarantee, and any Indebtedness of such Subsidiary shall be deemed to be Incurred by a Restricted Subsidiary of the Parent as of such date (and, if such Indebtedness is not permitted to be Incurred as of such date under this Section 1004, the Parent shall be in Default of this covenant). (k) For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Indebtedness, the U.S. Dollar Equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-dominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-dominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 1004, the maximum amount of Indebtedness that the Parent may Incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Indebtedness Incurred to refinance other Indebtedness, if Incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing. Section 1005 Limitation on Restricted Payments (l) The Parent will not, and will not permit any of its Restricted Subsidiaries, directly or indirectly, to: (1) declare or pay any dividend or make any distribution on or in respect of its Capital Stock (including any payment in connection with any merger or consolidation involving the Parent or any of its Restricted Subsidiaries) except: (A) dividends or distributions payable in Capital 51 Stock of the Parent (other than Disqualified Stock) or in options, warrants or other rights to purchase such Capital Stock of the Parent; and (B) dividends or distributions payable to the Parent or a Restricted Subsidiary of the Parent (and if such Restricted Subsidiary is not a Wholly Owned Subsidiary, to its other holders of common Capital Stock on a pro rata basis); (2) purchase, redeem, retire or otherwise acquire for value any Capital Stock of the Parent or any direct or indirect parent of the Parent held by Persons other than the Parent or a Restricted Subsidiary of the Parent (other than in exchange for Capital Stock of the Parent (other than Disqualified Stock)); (3) purchase, repurchase, redeem, defease or otherwise acquire or retire for value, prior to scheduled maturity, scheduled repayment or scheduled sinking fund payment, any Subordinated Obligations of the Parent or the Subsidiary Issuer (other than the purchase, repurchase, redemption, defeasance or other acquisition or retirement of Subordinated Obligations purchased in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of purchase, repurchase, redemption, defeasance or other acquisition or retirement); or (4) make any Restricted Investment in any Person; (any such dividend, distribution, purchase, redemption, repurchase, defeasance, other acquisition, retirement or Restricted Investment referred to in clauses (1) through (4) of this Section 1005(a) shall be referred to herein as a "Restricted Payment"), if at the time the Parent or such Restricted Subsidiary makes such Restricted Payment: (A) a Default shall have occurred and be continuing (or would result therefrom); or (B) the Parent is not able to Incur an additional $1.00 of Indebtedness pursuant to Section 1004(a) after giving effect, on a pro forma basis, to such Restricted Payment; or (C) the aggregate amount of such Restricted Payment and all other Restricted Payments declared or made subsequent to the Issue Date would exceed the sum of: (i) 50% of Consolidated Net Income for the period (treated as one accounting period) from the beginning of the first fiscal quarter commencing after the date of this Indenture to the end of the most recent fiscal quarter ending prior to the date of such Restricted Payment for which financial statements are in existence (or, in case such Consolidated Net Income is a deficit, minus 100% of such deficit); plus (ii) 100% of the aggregate Net Cash Proceeds received by the Parent from the issue or sale of its Capital Stock (other than Disqualified Stock) or other 52 capital contributions subsequent to the Issue Date (other than Net Cash Proceeds received from an issuance or sale of such Capital Stock to a Subsidiary of the Parent or an employee stock ownership plan, option plan or similar trust to the extent such sale to an employee stock ownership plan or similar trust is financed by loans from or Guaranteed by the Parent or any Restricted Subsidiary unless such loans have been repaid with cash on or prior to the date of determination); plus (iii) the amount by which Indebtedness of the Parent or its Restricted Subsidiaries is reduced on the Parent's balance sheet upon the conversion or exchange (other than by a Subsidiary of the Parent) subsequent to the Issue Date of any Indebtedness of the Parent or its Restricted Subsidiaries convertible or exchangeable for Capital Stock (other than Disqualified Stock) of the Parent (less the amount of any cash, or the fair market value of any other property, distributed by the Parent upon such conversion or exchange); plus (iv) the amount equal to the net reduction in Restricted Investments made by the Parent or any of its Restricted Subsidiaries in any Person resulting from: (A) repurchases or redemptions of such Restricted Investments by such Person, proceeds realized upon the sale of such Restricted Investment to an unaffiliated purchaser, repayments of loans or advances or other transfers of assets (including by way of dividend or distribution) by such Person to the Parent or any Restricted Subsidiary of the Parent; or (B) the redesignation of Unrestricted Subsidiaries as Restricted Subsidiaries (valued in each case as provided in the definition of "Investment") not to exceed, in the case of any Unrestricted Subsidiary, the amount of Investments previously made by the Parent or any Restricted Subsidiary in such Unrestricted Subsidiary, which amount in each case under this clause (iv) was included in the calculation of the amount of Restricted Payments; provided, however, that no amount will be included under this clause (iv) to the extent it is already included in Consolidated Net Income. 53 (m) The foregoing provisions of Section 1005(a) will not prohibit: (1) any purchase, repurchase, redemption, defeasance or other acquisition or retirement of Capital Stock, Disqualified Stock or Subordinated Obligations of the Parent or the Subsidiary Issuer made by exchange for, or out of the proceeds of the substantially concurrent sale of, Capital Stock of the Parent (other than Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary or an employee stock ownership plan or similar trust to the extent such sale to an employee stock ownership plan or similar trust is financed by loans from or Guaranteed by the Parent or any Restricted Subsidiary unless such loans have been repaid with cash on or prior to the date of determination); provided, however, that (a) such purchase, repurchase, redemption, defeasance, acquisition or retirement will be excluded in subsequent calculations of the amount of Restricted Payments and (b) the Net Cash Proceeds from such sale of Capital Stock will be excluded from clause (c)(ii) of the preceding paragraph; and provided, further, that for purposes of this clause (1), any sale made within 30 days of such purchase, repurchase, redemption, defeasance or other acquisition or retirement, shall be deemed to be a "substantially current sale"; (2) any purchase, repurchase, redemption, defeasance or other acquisition or retirement of Subordinated Obligations of the Parent or the Subsidiary Issuer made by exchange for, or out of the proceeds of the substantially concurrent sale of, Subordinated Obligations of the Parent or the Subsidiary Issuer that, in each case, is permitted to be Incurred pursuant to Section 1004 and that in each case constitutes Refinancing Indebtedness; provided, however, that such purchase, repurchase, redemption, defeasance, acquisition or retirement will be excluded in subsequent calculations of the amount of Restricted Payments; (3) any purchase, repurchase, redemption, defeasance or other acquisition or retirement of Disqualified Stock of the Parent or a Restricted Subsidiary made by exchange for or out of the proceeds of the substantially concurrent sale of Disqualified Stock of the Parent or such Restricted Subsidiary, as the case may be, that, in each case, is permitted to be Incurred pursuant to Section 1004 and that in each case constitutes Refinancing Indebtedness; provided, however, that such purchase, repurchase, redemption, defeasance, acquisition or retirement will be 54 excluded in subsequent calculations of the amount of Restricted Payments; (4) so long as no Default or Event of Default has occurred and is continuing, any purchase or redemption of Subordinated Obligations from Net Available Cash to the extent permitted under Section 1009; provided, however, that such purchase or redemption will be excluded in subsequent calculations of the amount of Restricted Payments; (5) dividends paid within 60 days after the date of declaration if at such date of declaration such dividend would have complied with this provision; provided, however, that such dividends will be included in subsequent calculations of the amount of Restricted Payments; (6) so long as no Default or Event of Default has occurred and is continuing, (1) the purchase, redemption or other acquisition, cancellation or retirement for value of Capital Stock, or options, warrants, equity appreciation rights or other rights to purchase or acquire Capital Stock of the Parent or any Restricted Subsidiary of the Parent or any parent of the Parent held by any existing or former employees or management of the Parent or any Subsidiary of the Parent or their assigns, estates or heirs, in each case in connection with the repurchase provisions under employee stock option or stock purchase agreements or other agreements to compensate management employees; provided that such redemptions or repurchases pursuant to this clause will not exceed $2 million in the aggregate during any calendar year (with 50% of the unused amounts in any calendar year being carried over to succeeding calendar years); provided, further, however, that such amount in any calendar year may be increased by an amount not to exceed (A) the cash proceeds received by the Parent from the sale of Capital Stock of the Parent to members of management or directors of the Parent and its Restricted Subsidiaries that occurs after the Issue Date (to the extent the cash proceeds from the sale of such Equity Interests have not otherwise been applied to the payment of Restricted Payments by virtue of the preceding paragraph (c)), plus (B) up to $2 million of any cash proceeds of key man 55 life insurance policies received by the Parent and its Restricted Subsidiaries after the Issue Date, less (C) the amount of any Restricted Payments made pursuant to clauses (A) and (B) of this clause (6)(a); provided, further, however, that the amount of any such repurchase or redemption will be included in subsequent calculations of the amount of Restricted Payments; and (2) loans or advances to employees of the Parent or employees or directors of any Subsidiary of the Parent, in each case as permitted by the Section 402 of the Sarbanes-Oxley Act of 2002, the proceeds of which are used to purchase Capital Stock of the Parent, in an aggregate amount not in excess of $2 million at any one time outstanding; provided, however, that the amount of such loans and advances will be included in subsequent calculations of the amount of Restricted Payments; (7) so long as no Default or Event of Default has occurred and is continuing, the declaration and payment of dividends to holders of any class or series of Disqualified Stock of the Parent issued in accordance with the terms of this Indenture to the extent such dividends are included in the definition of "Consolidated Interest Expense"; provided that the payment of such dividends will be excluded from subsequent calculations of the amount of Restricted Payments; (8) repurchases of Capital Stock deemed to occur upon the exercise of stock options, warrants or other convertible securities if such Capital Stock represents a portion of the exercise price thereof; provided, however, that such repurchases will be excluded from subsequent calculations of the amount of Restricted Payments; (9) the payment of reasonable and customary directors' fees to the members of the Board of Directors of the Parent; provided that such fees are consistent with past practice or current requirements; (10) the purchase by the Parent of fractional shares arising out of stock dividends, splits or combinations or business combinations; and 56 (11) Restricted Payments in an amount not to exceed $25 million; provided that the amount of such Restricted Payments will be included in subsequent calculations of the amount of Restricted Payments. (n) The amount of all Restricted Payments (other than cash) shall be the fair market value on the date of such Restricted Payment of the asset(s) or securities proposed to be paid, transferred or issued by the Parent or such Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment. The fair market value of any cash Restricted Payment shall be its face amount and any non cash Restricted Payment shall be determined conclusively by the Board of Directors of the Parent acting in good faith whose resolution with respect thereto shall be delivered to the Trustee, such determination to be based upon an opinion or appraisal issued by an accounting, appraisal or investment banking firm of national standing if such fair market value is estimated in good faith by the Board of Directors of the Parent to exceed $25 million. Not later than the date of making any Restricted Payment, the Parent shall deliver to the Trustee an Officers' Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by this Section 1005 were computed, together with a copy of any fairness opinion or appraisal required by this Indenture. Section 1006 Limitation on Layering The Parent will not Incur any Indebtedness if such Indebtedness is subordinate or junior in ranking in any respect to any Senior Indebtedness of the Parent unless such Indebtedness is Senior Subordinated Indebtedness of the Parent or is contractually subordinated in right of payment to Senior Subordinated Indebtedness of the Parent. Unsecured Indebtedness of the Parent is not deemed to be subordinate or junior to secured Indebtedness of the Parent merely because it is unsecured. The Subsidiary Issuer will not Incur any Indebtedness if such Indebtedness is subordinate or junior in ranking in any respect to any Senior Indebtedness of the Subsidiary Issuer unless such Indebtedness is Senior Subordinated Indebtedness of the Subsidiary Issuer or is contractually subordinated in right of payment to Senior Subordinated Indebtedness of the Subsidiary Issuer. Unsecured Indebtedness of the Subsidiary Issuer is not deemed to be subordinate or junior to secured Indebtedness of the Subsidiary Issuer merely because it is unsecured. Section 1007 Limitation on Liens The Parent will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, Incur or suffer to exist any Lien (other than Permitted Liens) upon any of its property or assets (including Capital Stock of Restricted Subsidiaries of the Parent), whether owned on the date of this 57 Indenture or acquired after that date, which Lien is securing any Senior Subordinated Indebtedness of the Parent or any Restricted Subsidiary or Subordinated Obligations of the Parent or any Restricted Subsidiary, unless contemporaneously with the Incurrence of such Liens effective provision is made to secure the Indebtedness due under this Indenture and the Notes, equally and ratably with (or prior to in the case of Liens with respect to Subordinated Obligations of the Parent or the Subsidiary Issuer) the Indebtedness secured by such Lien for so long as such Indebtedness is so secured. Section 1008 Limitation on Restrictions on Distributions from Restricted Subsidiaries (o) The Parent will not, and will not permit any Restricted Subsidiary to, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary to: (1) pay dividends or make any other distributions on its Capital Stock or pay any Indebtedness or other obligations owed to the Parent or any Restricted Subsidiary (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on Common Stock shall not be deemed a restriction on the ability to make distributions on Capital Stock); (2) make any loans or advances to the Parent or any Restricted Subsidiary (it being understood that the subordination of loans or advances made to the Parent or any Restricted Subsidiary to other Indebtedness Incurred by the Parent or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances); or (3) transfer any of its property or assets to the Parent or any Restricted Subsidiary. (p) The foregoing provisions of Section 1008(a) will not prohibit: (1) any encumbrance or restriction pursuant to an agreement in effect at or entered into on the date of this Indenture, including, without limitation, this Indenture and the Credit Facility in effect on such date; (2) any encumbrance or restriction with respect to a Restricted Subsidiary pursuant to an agreement relating to any Capital Stock or Indebtedness Incurred by a Restricted Subsidiary on or before the date on which such Restricted Subsidiary was acquired by the Parent (other than Capital Stock or 58 Indebtedness Incurred as consideration in, or to provide all or any portion of the funds utilized to consummate, the transaction or series of related transactions pursuant to which such Restricted Subsidiary became a Restricted Subsidiary or was acquired by the Parent or in contemplation of the transaction) and outstanding on such date; (3) any encumbrance or restriction with respect to a Restricted Subsidiary pursuant to an agreement effecting a refunding, replacement or refinancing of Indebtedness Incurred pursuant to an agreement referred to in Section 1008(b)(1), Section 1008(b)(2), this Section 1008(b)(3) or Section 1008(b)(4) or contained in any amendment to an agreement referred to in Section 1008(b)(1), Section 1008(b)(2), this Section 1008(b)(3) or Section 1008(b)(4); provided, however, that the encumbrances and restrictions with respect to such Restricted Subsidiary contained in any such agreement are no less favorable in any material respect to the Holders of the Notes than the encumbrances and restrictions contained in such agreements referred to in Section 1008(b)(1), Section 1008(b)(2) or Section 1008(b)(4) on the Issue Date or the date such Restricted Subsidiary became a Restricted Subsidiary, whichever is applicable; (4) in the case of Section 1008(a)(3), any encumbrance or restriction: (a) that restricts in a customary manner the subletting, assignment or transfer of any property or asset that is subject to a lease, farm-in agreement or farm-out agreement, license or similar contract, or the assignment or transfer of any such lease, license or other contract; (b) contained in mortgages, pledges or other security agreements permitted under this Indenture securing Indebtedness of the Parent or a Restricted Subsidiary to the extent such encumbrances or restrictions restrict the transfer of the property subject to such mortgages, pledges or other security agreements; (c) pursuant to customary provisions restricting dispositions of real property interests set forth in 59 any reciprocal easement agreements of the Parent or any Restricted Subsidiary; or (d) with respect to the disposition or distribution of assets or property in operating agreements, joint venture agreements, development agreements, area of mutual interest agreements and other agreements that are customary in the Oil and Gas Business and entered into in the ordinary course of business; (5) (a) purchase money obligations for property acquired in the ordinary course of business and (b) Capitalized Lease Obligations permitted under this Indenture, in each case, that impose encumbrances or restrictions of the nature described in Section 1008(a)(3) on the property so acquired; (6) any restriction with respect to a Restricted Subsidiary (or any of its property or assets) imposed pursuant to an agreement entered into for the direct or indirect sale or disposition of all or substantially all the Capital Stock or assets of such Restricted Subsidiary (or the property or assets that are subject to such restriction) pending the closing of such sale or disposition; (7) customary provisions in joint venture agreements and other similar agreements entered into in the ordinary course of business; (8) net worth provisions in leases and other agreements entered into by the Parent or any Restricted Subsidiary in the ordinary course of business; and (9) encumbrances or restrictions arising or existing by reason of applicable law or any applicable rule, regulation or order. Section 1009 Limitation on Sales of Assets and Subsidiary Stock (q) The Parent will not, and will not permit any of its Restricted Subsidiaries to, make any Asset Disposition unless: (1) the Parent or such Restricted Subsidiary, as the case may be, receives consideration at least equal to the fair market value (such fair market value to be determined on the date of contractually agreeing to such Asset Disposition), as determined in good faith by the Board of Directors in the case of an Asset Disposition for consideration exceeding 60 $20 million (including as to the value of all non cash consideration), of the shares and assets subject to such Asset Disposition; (2) at least 75% of the consideration from such Asset Disposition received by the Parent or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents; and (3) an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Parent or such Restricted Subsidiary, as the case may be: (i) first, to the extent the Parent or any Restricted Subsidiary, as the case may be, elects (or is required by the terms of any Senior Indebtedness), to prepay, repay or purchase Senior Indebtedness or Indebtedness of a Restricted Subsidiary (in each case other than Indebtedness owed to the Parent or an Affiliate of the Parent) within 365 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; provided, however, that, in connection with any prepayment, repayment or purchase of Indebtedness pursuant to this clause (a), the Parent or such Restricted Subsidiary will retire such Indebtedness and will cause the related commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid or purchased; and (ii) second, to the extent of the balance of such Net Available Cash after application in accordance with clause (a), to the extent the Parent or such Restricted Subsidiary elects, to invest in Additional Assets within 365 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; provided that pending the final application of any such Net Available Cash in accordance with clause (i) or clause (ii) above, the Parent and its Restricted Subsidiaries may temporarily reduce Indebtedness or otherwise invest such Net Available Cash in any manner not prohibited by this Indenture. 61 (b) Any Net Available Cash from Asset Dispositions that are not applied or invested as provided in the preceding paragraph will be deemed to constitute "Excess Proceeds." On the 366th day after an Asset Disposition, if the aggregate amount of Excess Proceeds exceeds $10 million, a "triggering event" shall be deemed to have occurred, which will result in the obligation of the Parent and the Subsidiary Issuer to make an offer ("Asset Disposition Offer") to all Holders of Units, and to the extent required by the terms of other Senior Subordinated Indebtedness, to all holders of other Senior Subordinated Indebtedness outstanding with similar provisions requiring the Parent and the Subsidiary Issuer to make an offer to purchase such Senior Subordinated Indebtedness with the proceeds from any Asset Disposition ("Pari Passu Notes"), to purchase the maximum number of Units, and the maximum principal amount of any such Pari Passu Notes to which the Asset Disposition Offer applies that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount of the Notes comprising the Units and of the Pari Passu Notes plus accrued and unpaid interest to the date of purchase, in accordance with the procedures set forth in this Indenture or the agreements governing the Pari Passu Notes, as applicable, as whole Units in the case of the Units and in integral multiples of $1,000 in the case of the Pari Passu Notes. To the extent that the aggregate amount of Notes comprising Units and Pari Passu Notes so validly tendered and not properly withdrawn pursuant to an Asset Disposition Offer is less than the Excess Proceeds, the Parent or the Subsidiary Issuer may use any remaining Excess Proceeds for general corporate purposes, subject to other covenants contained in this Indenture. If the aggregate principal amount of Notes comprising Units surrendered by Holders thereof and other Pari Passu Notes surrendered by holders or lenders, collectively, exceeds the amount of Excess Proceeds, the Trustee shall select the Units and Pari Passu Notes to be purchased on a pro rata basis on the basis of the aggregate principal amount of tendered Units and Pari Passu Notes. Upon completion of such Asset Disposition Offer, the amount of Excess Proceeds shall be reset at zero. (c) The Asset Disposition Offer will remain open for a period of 20 Business Days following its commencement, except to the extent that a longer period is required by applicable law (the "Asset Disposition Offer Period"). No later than five Business Days after the termination of the Asset Disposition Offer Period (the "Asset Disposition Purchase Date"), the Parent and the Subsidiary Issuer will purchase the principal amount of Units and Pari Passu Notes required to be purchased pursuant to this covenant (the "Asset Disposition Offer Amount") or, if less than the Asset Disposition Offer Amount has been so validly tendered, all Units and Pari Passu Notes validly tendered in response to the Asset Disposition Offer. (d) If the Asset Disposition Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Units pursuant to the Asset Disposition Offer. 62 (e) On or before the Asset Disposition Purchase Date, the Parent and the Subsidiary Issuer will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Asset Disposition Offer Amount of Units, and Pari Passu Notes or portions of Units and Pari Passu Notes so validly tendered and not properly withdrawn pursuant to the Asset Disposition Offer, or if less than the Asset Disposition Offer Amount has been validly tendered and not properly withdrawn, all Units and Pari Passu Notes so validly tendered and not properly withdrawn, as whole Units in the case of the Units and in integral multiples of $1,000 in the case of the Pari Passu Notes. The Parent and the Subsidiary Issuer will deliver to the Trustee an Officers' Certificate stating that the Units were accepted for payment by the Parent and the Subsidiary Issuer in accordance with the terms of this covenant and, in addition, the Parent and the Subsidiary Issuer will deliver all certificates and notes required, if any, by the agreements governing the Pari Passu Notes. The Parent, the Subsidiary Issuer or the Paying Agent, as the case may be, will promptly (but in any case not later than five Business Days after termination of the Asset Disposition Offer Period) mail or deliver to each tendering Holder of Units or holder or lender of Pari Passu Notes, as the case may be, an amount equal to the purchase price of the Notes comprising the Units or Pari Passu Notes so validly tendered and not properly withdrawn by such holder or lender, as the case may be, and accepted by the Parent and the Subsidiary Issuer for purchase, and the Parent and the Subsidiary Issuer will promptly issue new Notes comprising a new Unit, and the Trustee, upon delivery of an Officers' Certificate from the Parent will authenticate and mail or deliver such new Units to such Holder, in a principal amount equal to any unpurchased portion of the Units surrendered; provided that such new Unit will be a whole Unit or an integral multiple of a whole Unit. For the sake of clarification, in no event shall such new Notes be considered to be a new issuance of Indebtedness by the Parent or the Subsidiary Issuer. In addition, the Parent and the Subsidiary Issuer will take any and all other actions required by the agreements governing the Pari Passu Notes. Any Unit not so accepted will be promptly mailed or delivered by the Parent and the Subsidiary Issuer to the Holder thereof. The Parent and the Subsidiary Issuer will publicly announce the results of the Asset Disposition Offer on the Asset Disposition Purchase Date. (f) For the purposes of this Section 1009, the following will be deemed to be cash: (1) the assumption by the transferee of Indebtedness (other than Subordinated Obligations or Disqualified Stock) of the Parent or Indebtedness of a Restricted Subsidiary and the release of the Parent or such Restricted Subsidiary from all liability on such Indebtedness in connection with such Asset Disposition (in which case the Parent will, without further action, be deemed to have applied such deemed cash to Indebtedness in accordance with Section 1009(a)(3)(i); and 63 (2) securities, notes or other obligations received by the Parent or any Restricted Subsidiary of the Parent from the transferee that are converted by the Parent or such Restricted Subsidiary into cash within 60 days. (g) The Parent will not, and will not permit any Restricted Subsidiary to, engage in any Asset Swaps, unless: (1) in the event such Asset Swap involves the transfer by the Parent or any Restricted Subsidiary of assets having an aggregate fair market value, as determined by the Board of Directors of the Parent in good faith, in excess of $10 million, the terms of such Asset Swap have been approved by a majority of the members of the Board of Directors of the Parent; and (2) in the event such Asset Swap involves the transfer by the Parent or any Restricted Subsidiary of assets having an aggregate fair market value, as determined by the Board of Directors of the Parent in good faith, in excess of $25 million, the Parent has received a written opinion from an independent investment banking firm of nationally recognized standing that such Asset Swap is fair to the Parent or such Restricted Subsidiary, as the case may be, from a financial point of view. (h) The Parent and the Subsidiary Issuer will 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 repurchase of Units pursuant to this Indenture. To the extent that the provisions of any securities laws or regulations conflict with provisions of this covenant, the Parent and the Subsidiary Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Indenture by virtue of any conflict. The provisions under this Indenture relative to the Parent's and the Subsidiary Issuer's obligation to make an offer to repurchase Units as a result of an Asset Disposition may be waived or modified with the written consent of the Holders of a majority in principal amount of the Notes comprising the Units. Section 1010 Limitation on Affiliate Transactions (a) The Parent will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or conduct any transaction (including the purchase, sale, lease or exchange of any property or the rendering of any service) with any Affiliate of the Parent (an "Affiliate Transaction") unless: 64 (1) the terms of such Affiliate Transaction are no less favorable to the Parent or such Restricted Subsidiary, as the case may be, than those that could be obtained in a comparable transaction at the time of such transaction in arm's length dealings with a Person who is not such an Affiliate; (2) in the event such Affiliate Transaction involves an aggregate consideration in excess of $5 million, an Officers' Certificate certifying that such Affiliate Transaction satisfies the criteria in clause (a)(1) of this Section 1010 shall have been delivered to the Trustee; (3) in the event such Affiliate Transaction involves an aggregate consideration in excess of $10 million, the terms of such transaction have been approved by a majority of the members of the Board of Directors of the Parent and by a majority of the members of such Board having no personal stake in such transaction, if any (and such majority or majorities, as the case may be, determines that such Affiliate Transaction satisfies the criteria in Section 1013(a)(1)); and (4) in the event such Affiliate Transaction involves an aggregate consideration in excess of $25 million, the Parent has received a written opinion from an independent investment banking, accounting or appraisal firm of nationally recognized standing that such Affiliate Transaction is not materially less favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm's length basis from a Person that is not an Affiliate. (b) The foregoing Section 1010(a) will not apply to: (1) any Restricted Payment or any Permitted Investment permitted to be made pursuant to Section 1005; (2) any issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, employment agreements and other compensation arrangements, options to purchase Capital Stock of the Parent, restricted stock plans, long-term incentive plans, stock appreciation rights plans, participation plans or similar employee benefits plans and/or indemnity provided on behalf of officers and employees approved by the Board of Directors; 65 (3) loans or advances to employees, officers or directors in the ordinary course of business of the Parent or any of its Restricted Subsidiaries, in each case only as permitted by Section 402 of the Sarbanes Oxley Act of 2002, but in any event not to exceed $2 million in the aggregate outstanding at any one time with respect to all loans or advances made since the Issue Date; (4) any transaction between the Parent and a Restricted Subsidiary or between Restricted Subsidiaries and Guarantees issued by the Parent or a Restricted Subsidiary for the benefit of the Parent or a Restricted Subsidiary, as the case may be, in accordance with Section 1004; (5) the payment of reasonable and customary fees and compensation paid to, and indemnity provided on behalf of, officers and directors of the Parent or any Restricted Subsidiary of the Parent; and (6) the performance of obligations of the Parent or any of its Restricted Subsidiaries under the terms of any agreement to which the Parent or any of its Restricted Subsidiaries is a party as of or on the Issue Date and identified on a schedule to this Indenture on the Issue Date, as these agreements may be amended, modified, supplemented, extended or renewed from time to time; provided, however, that any future amendment, modification, supplement, extension or renewal entered into after the Issue Date will be permitted to the extent that its terms are not more disadvantageous to the Holders of the Units than the terms of the agreements in effect on the Issue Date. Section 1011 Limitation on Sale of Capital Stock of Restricted Subsidiaries (a) The Parent will not, and will not permit any Restricted Subsidiary of the Parent to, transfer, convey, sell, lease or otherwise dispose of any Voting Stock of any Restricted Subsidiary or to issue any of the Voting Stock of a Restricted Subsidiary (other than, if necessary, shares of its Voting Stock constituting directors' qualifying shares) to any Person except: (1) to the Parent or a Wholly Owned Subsidiary; or (2) in compliance with Section 1009 and immediately after giving effect to such issuance or sale, such Restricted Subsidiary would continue to be a Restricted Subsidiary. 66 (b) Notwithstanding the preceding paragraph, the Parent may sell all the Voting Stock of a Restricted Subsidiary as long as the Parent complies with Section 1009. Section 1012 SEC Reports Notwithstanding that the Parent may not be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, to the extent permitted by the Exchange Act, the Parent will file with the SEC, and make available to the Trustee and the registered Holders of the Units, the annual reports and the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) that are specified in Sections 13 and 15(d) of the Exchange Act within the time periods specified therein. In the event that the Parent is not permitted to file such reports, documents and information with the SEC pursuant to the Exchange Act, the Parent will nevertheless make available such Exchange Act information to the Trustee and the Holders of the Units as if the Parent were subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act within the time periods specified therein. Section 1013 Future Subsidiary Guarantees The Parent will not permit any Restricted Subsidiary (other than a Foreign Subsidiary) to Guarantee the payment of any Indebtedness of the Parent or any other Subsidiary unless such Restricted Subsidiary simultaneously executes and delivers a supplemental indenture to this Indenture providing for a Subsidiary Guarantee of such Restricted Subsidiary pursuant to this Indenture the form of which is attached hereto as Exhibit E. Notwithstanding the foregoing and the other provisions of this Indenture, in the event a Subsidiary Guarantor is sold or disposed of (whether by merger, consolidation, the sale of its Capital Stock or the sale of all or substantially all of its assets (other than by lease) and whether or not the Subsidiary Guarantor is the surviving corporation in such transaction) to a Person which is not the Parent or a Restricted Subsidiary, such Subsidiary Guarantor will be released from its obligations under its Subsidiary Guarantee if: (1) the sale or other disposition is in compliance with this Indenture, including Section 1009 and Section 1011; and (2) the Guarantee which required the creation of the Subsidiary Guarantee is released or discharged, except a discharge or release by or as a result of payment under such Guarantee. In addition, a Subsidiary Guarantor will be released from its obligations under this Indenture and the Subsidiary Guarantee if the Parent designates such Subsidiary as an Unrestricted Subsidiary in accordance with this Indenture. Section 1014 Limitation on Lines of Business 67 The Parent will not, and will not permit any Restricted Subsidiary to, engage in any business other than the Oil and Gas Business, except to such extent as would not be material in the opinion of the Board of Directors of the Parent (which opinion shall be reasonable and made in good faith) to the Parent and its Restricted Subsidiaries taken as a whole. Section 1015 Payments for Consent None of the Parent, the Subsidiary Issuer or any of the Restricted Subsidiaries will, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fees or otherwise, to any Holder of any Notes or Units for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid or is paid to all Holders of the Notes or Units that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment. Section 1016 [Reserved] Section 1017 Change of Control If a Change of Control occurs, then such Change of Control shall constitute a "triggering event" which shall result in the obligation of the Parent and the Subsidiary Issuer make an offer to repurchase from each Holder in all or any part of such holder's Units (as whole Units or an integral multiple thereof), at a purchase price in cash equal to 101% of the principal amount of the Notes comprising the Units plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date). Within 30 days following any Change of Control, the Parent and the Subsidiary Issuer will mail a notice (the "Change of Control Offer") to each Holder with a copy to the Trustee stating: (1) that a Change of Control has occurred and that such Holder has the right to require the Parent and the Subsidiary Issuer to purchase such holder's Units at a purchase price in cash equal to 101% of the principal amount of the Notes comprising such Units plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on a record date to receive interest on the relevant interest payment date) (the "Change of Control Payment"); (2) the repurchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed) (the "Change of Control Payment Date"); and (3) the procedures determined by the Parent and the Subsidiary Issuer, consistent with this Indenture, that a Holder must follow in order to have its Units repurchased. On or before the Change of Control Payment Date, the Parent and the Subsidiary Issuer will, to the extent lawful: (1) accept for payment all Units (as whole Units or in integral multiples thereof) properly tendered pursuant to the 68 Change of Control Offer; (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Units so tendered; and (3) deliver or cause to be delivered to the Trustee the Units so accepted together with an Officers' Certificate stating the number of Units being purchased by the Parent and the Subsidiary Issuer. The Paying Agent will promptly mail to each Holder of Units so tendered the Change of Control Payment for such Units, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder Notes comprising new Units equal in principal amount to, and evidencing the same Indebtedness as any unpurchased portion of the Units surrendered, if any; provided that each such Unit will be as whole Units or an integral multiple thereof. If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest, if any, will be paid to the Person in whose name a Unit is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender pursuant to the Change of Control Offer. Prior to mailing a Change of Control Offer, and as a condition to such mailing (i) all Senior Indebtedness must be repaid in full, or the Parent and the Subsidiary Issuer must offer to repay all Senior Indebtedness and make payment to the Holders that accept such offer and obtain waivers of any event of default from the remaining holders of such Senior Indebtedness whose holders accept such offer or (ii) the requisite holders of each issue of Senior Indebtedness shall have consented to such Change of Control Offer being made. The Parent and the Subsidiary Issuer jointly covenant to effect such repayment or obtain such consent within 30 days following any Change of Control, it being a Default of this Section 1017 if the Parent or the Subsidiary Issuer fails to comply with this Section. Neither the Parent nor the Subsidiary Issuer will be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Parent and the Subsidiary Issuer and purchases all Units validly tendered and not withdrawn under such Change of Control Offer. The Parent and the Subsidiary Issuer will 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 repurchase of Units pursuant to this Section 1017. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Indenture, the Parent and the Subsidiary Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations described in this Indenture by virtue of the conflict. 69 Section 1018 Statement by Officers as to Default (a) The Parent and the Subsidiary Issuer each will deliver to the Trustee, within 90 days after the end of each fiscal year of the Parent and the Subsidiary Issuer ending after the date hereof, an Officer's Certificate, stating whether or not to the best knowledge of the signers thereof the Parent or the Subsidiary Issuer, as the case may be, is in Default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Parent or the Subsidiary Issuer, as the case may be, shall be in Default, specifying all such Defaults and the nature and status thereof of which they may have knowledge. (b) The Parent or the Subsidiary Issuer, as the case may be, shall deliver to the Trustee, as soon as possible and in any event within five days after the Parent or the Subsidiary Issuer, as the case may be, becomes aware or should reasonably become aware of the occurrence of a Default or an Event of Default, an Officer's Certificate setting forth the details of such Default or Event of Default, and the action which the Parent or the Subsidiary Issuer, as the case may be, proposes to take with respect thereto. Section 1019 Effectiveness of Covenants The covenants described under Sections 1004, Section 1005, Section 1008, Section 1009, Section 1010, Section 1011, Section 1014 and clause (3) under Section 801 (collectively, the "Suspended Covenants"), will no longer be in effect upon (a) both the Parent Notes and the Subsidiary Notes having an Investment Grade Rating from both S&P and Moody's and (b) no Default or Event of Default having occurred and continuing under this Indenture. In the event that the Parent, the Subsidiary Issuer and the Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the preceding sentence and, subsequently, one or both of the rating agencies named above withdraws its ratings or downgrades the rating assigned to the Notes below the required Investment Grade Ratings or a Default or Event of Default occurs and is continuing, then the Parent, the Subsidiary Issuer and the Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants and compliance with the Suspended Covenants, unless and until the conditions set forth in the previous sentence are again satisfied. Notwithstanding that the Suspended Covenants may be reinstated, no default will be deemed to have occurred as a result of failure to comply with the Suspended Covenants during such suspension. Compliance with the Suspended Covenants with respect to Restricted Payments made after the time of such withdrawal, downgrade, Default or Event of Default will be calculated pursuant to Section 1005 as though such covenant had been in effect during the entire period of time from the date the Notes are issued." 70 SECTION 2.4. SUCCESSOR COMPANY Article Eight of the Original Indenture is supplemented, amended and restated to read in its entirety as follows. "Article Eight SUCCESSOR COMPANY Section 801 Merger and Consolidation The Parent will not consolidate with or merge with or into, or convey, transfer or lease all or substantially all its assets to, any Person, unless: (1) the resulting, surviving or transferee Person (the "Successor Company") will be a corporation, partnership, trust or limited liability company organized and existing under the laws of the United States of America, any State of the United States or the District of Columbia and the Successor Company (if not the Parent) will expressly assume, by supplemental indenture, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of the Parent under the Parent Notes, the Parent Guarantee and this Indenture; (2) immediately after giving effect to such transaction (and treating any Indebtedness that becomes an obligation of the Successor Company or any Subsidiary of the Successor Company as a result of such transaction as having been Incurred by the Successor Company or such Subsidiary at the time of such transaction), no Default or Event of Default shall have occurred and be continuing; (3) immediately after giving effect to such transaction, the Successor Company would be able to Incur at least an additional $1.00 of Indebtedness pursuant to Section 1004(a); and (4) the Parent shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with this Indenture. For purposes of this Section 801, the sale, lease, conveyance, assignment, transfer, or other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of the Parent, which properties and assets, if held by the Parent instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Parent on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Parent. The Successor Company will succeed to, and be substituted for, and may exercise every right and power of, the Parent under this Indenture. 71 Notwithstanding the preceding clause (3) of this Section 801, (x) any Restricted Subsidiary of the Parent may consolidate with, merge into or transfer all or part of its properties and assets to the Parent and (y) the Parent may merge with an Affiliate incorporated solely for the purpose of reincorporating the Parent in another jurisdiction to realize tax benefits; provided that, in the case of a Restricted Subsidiary that merges into the Parent, the Parent will not be required to comply with the preceding clause (4) of this Section 801. The Subsidiary Issuer will not consolidate with or merge with or into, or convey, transfer or lease all or substantially all its assets to, any Person other than the Parent or any Restricted Subsidiary. The Subsidiary Issuer may consolidate with or merge with or into, or convey, transfer or lease all or substantially all its assets to the Parent or any Restricted Subsidiary, if such Person will expressly assume, by supplemental indenture, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of the Subsidiary Issuer under the Subsidiary Notes and this Indenture. Thereupon, the Subsidiary Issuer will be fully released from its obligations under the Subsidiary Notes and the Parent or such Restricted Subsidiary, as applicable, will succeed to, and be substituted for, and may exercise every right and power of, the Subsidiary Issuer under the Subsidiary Notes and this Indenture and, in the case of a transaction in which the Parent is such successor, the Parent Guarantee will be automatically released, without any further action. Section 802 Assumption By Parent of Subsidiary Notes At any time at the joint option of the Parent and the Subsidiary Issuer, the Parent may assume, and the Subsidiary Issuer may assign, all of the Subsidiary Issuer's obligations with respect to all or, from time to time, part of the Subsidiary Notes, by supplemental indenture, executed and delivered to the Trustee, in form satisfactory to the Trustee. Upon such assumption, the Subsidiary Issuer will be fully released from its obligations under the Units and the Subsidiary Notes that have been so assigned and assumed and the Parent will succeed to the obligations of, and be substituted for, and may exercise every right and power of, the Subsidiary Issuer under this Indenture with respect to the Units and the Subsidiary Notes so assumed, and the Parent Guarantee will be automatically released, without any further action, with respect to the Units and the Subsidiary Notes so assumed."

SECTION 2.6. REMEDIES Article Five of each of the Original Indentures is supplemented, amended and restated to read in its entirety as follows: 76 "Article Five Remedies Section 501 Events of Default Each of the following is an "Event of Default": (1) default in any payment of interest on any Note when due, continued for 30 days, whether or not such payment is prohibited by the provisions described under Article Fifteen; (2) default in the payment of principal of or premium, if any, on any Note when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise, whether or not such payment is prohibited by the provisions described under Article Fifteen; (3) failure by the Parent or the Subsidiary Issuer to comply with its respective obligations under Article Ten or failure by the Parent to comply with its obligations under Article Thirteen; (4) failure by the Parent or the Subsidiary Issuer to comply for 30 days after notice with any of its respective obligations under Article Ten (in each case, other than a failure to purchase Units which will constitute an Event of Default under clause (2) of this Section 501 and other than a failure to comply with Section 801 which is covered by clause (3) of this Section 501); (5) failure by the Parent to comply for 60 days after notice with its other agreements contained in this Indenture; (6) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Parent or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Parent or any of its Restricted Subsidiaries), other than Indebtedness owed to the Parent or a Restricted Subsidiary, whether such Indebtedness or guarantee now exists, or is created after the date of this Indenture, which default: (a) is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness ("Payment Default"); or (b) results in the acceleration of such Indebtedness prior to its maturity (the "cross acceleration provision"); and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $10 million or more; 77 (7) (a) the Parent or a Significant Subsidiary or a group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Parent and its Restricted Subsidiaries), would constitute a Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law: (1) commences a voluntary case or proceeding; (2) consents to the entry of judgment, decree or order for relief against it in an involuntary case or proceeding; (3) consents to the appointment of a custodian of it or for any substantial part of its property; (4) makes a general assignment for the benefit of its creditors; or (5) consents to or acquiesces in the institution of a bankruptcy or an insolvency proceeding against it; or takes any comparable action under any foreign laws relating to insolvency; or (b) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (1) is for relief against the Parent or any Significant Subsidiary or a group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Parent and its Restricted Subsidiaries), would constitute a Significant Subsidiary in an involuntary case; (2) appoints a Custodian of the Parent or any Significant Subsidiary or a group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Parent and its Restricted Subsidiaries), would constitute a Significant Subsidiary or for any substantial part of its property; or (3) orders the winding up or liquidation of the Parent or any Significant Subsidiary or a group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Parent and its Restricted Subsidiaries) would constitute a Significant Subsidiary; or any similar relief is granted under any foreign laws and the order, decree or relief remains unstayed and in effect for 60 days; 78 (8) failure by the Parent or any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Parent and its Restricted Subsidiaries), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $10 million (net of any amounts that a reputable and creditworthy insurance company has acknowledged liability for in writing), which judgments are not paid, discharged or stayed for a period of 60 days. However, a default under clauses (4) and (5) of this Section 501 will not constitute an Event of Default until the Trustee or the Holders of 25% in principal amount of Notes (voting together as a single class) comprising the outstanding Units notify the Parent and the Subsidiary Issuer of the default and the Parent and the Subsidiary Issuer do not cure such default within the time specified in clauses (4) and (5) of this Section 501 paragraph after receipt of such notice. Section 502 Acceleration of Maturity; Rescission and Annulment If an Event of Default (other than an Event of Default described in clause (7) of Section 501) occurs and is continuing, the Trustee by notice to the Parent and the Subsidiary Issuer, or the Holders of at least 25% in principal amount of the Notes (voting together as a single class) comprising the outstanding Units by notice to the Parent, the Subsidiary Issuer and the Trustee, may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Notes to be due and payable. Upon such a declaration, such principal, premium and accrued and unpaid interest will be due and payable immediately. In the event of a declaration of acceleration of the Units because an Event of Default described in clause (6) of Section 501 has occurred and is continuing, the declaration of acceleration of the Units shall be automatically annulled if the event of default or Payment Default triggering such Event of Default pursuant to clause (6) of Section 501 shall be remedied or cured by the Parent or a Restricted Subsidiary of the Parent or waived by the Holders of the relevant Indebtedness within 20 days after the declaration of acceleration with respect thereto and if (1) the annulment of the acceleration of the Units would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, except nonpayment of principal, premium or interest on the Notes that became due solely because of the acceleration of the Notes, have been cured or waived. If an Event of Default described in clause (7) of Section 501 above occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all the Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. The Holders of a majority in principal amount of Notes (voting together as a single class) comprising the outstanding Units may waive all past defaults (except with respect to nonpayment of principal, premium or interest) and rescind any such acceleration with respect to the Units and its consequences if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, other than the nonpayment of 79 the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived. Section 503 Other Remedies If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of (or premium, if any) or interest on the Notes or to enforce the performance of any provision of the Units or this Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Units or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative. Section 504 Waiver of Past Defaults The Holders of a majority in principal amount of the outstanding Notes and Units by notice to the Trustee may (a) waive, by their consent (including, without limitation consents obtained in connection with a purchase of, or tender offer or exchange offer for, Units), an existing Default or Event of Default and its consequences except (i) a Default or Event of Default in the payment of the principal of, or premium, if any, or interest on a Note or (ii) a Default or Event of Default in respect of a provision that under Section 901 cannot be amended without the consent of each Holder affected and (b) rescind any such acceleration with respect to the Notes and its consequences if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived. When a Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right. Section 505 Control by Majority The Holders of a majority in principal amount of the outstanding Notes and Units may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 601 and Section 602, that the Trustee determines is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee 80 shall be entitled to indemnification satisfactory to it in its sole discretion against all fees, losses and expenses caused by taking or not taking such action. Section 506 Limitation on Suits Subject to Section 504, a Holder may not pursue any remedy with respect to this Indenture or the Notes or the Units unless: (1) such Holder has previously given the Trustee written notice stating that an Event of Default is continuing; (2) the Holders of at least 25% in principal amount of the Notes (voting together as a single class) comprising the outstanding Notes and Units have requested the Trustee to pursue the remedy; (3) such Holders have offered the Trustee reasonable security or indemnity against any loss, liability, fees and expense; (4) the Trustee has not complied with the request within 60 days after receipt of the request and the offer of security or indemnity; and (5) the Holders of a majority in principal amount of the outstanding Notes and Units have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request during such 60-day period. A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder. Section 507 Rights of Holders to Receive Payment Notwithstanding any other provision of this Indenture (including, without limitation, Section 506), the right of any Holder to receive payment of principal of, premium (if any) or interest on the Notes held by such Holder, on or after the respective due dates expressed in the Notes, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Notes. Section 508 Collection Suit by Trustee If an Event of Default specified in Section 501(1) or Section 501(2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Parent and the Subsidiary Issuer for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 607. Section 509 Trustee May File Proofs of Claim 81 The Trustee may file such proofs of claim and 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 agents and counsel) and the Holders allowed in any judicial proceedings relative to the Parent or the Subsidiary Issuer or its or their respective creditors or properties and, unless prohibited by law or applicable regulations, may be entitled and empowered to participate as a member of any official committee of creditors appointed in such matter and, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any custodian in any such judicial proceeding is hereby authorized by each holder to make 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 its counsel, and any other amounts due the Trustee under Section 607. Section 510 Priorities If the Trustee collects any money or property pursuant to this Article Five, it shall pay out the money or property in the following order: FIRST: to the Trustee for amounts due under Section 607; SECOND: subject to Article Twelve and Thirteen to Holders for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal and interest, respectively; and THIRD: to the Parent or the Subsidiary Issuer, as the case may be. The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section. At least 15 days before such record date, the Trustee shall mail to each Holder and to the Parent and the Subsidiary Issuer a notice that states the record date, the payment date and amount to be paid. Section 511 Undertaking for Costs 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 or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by the Parent and the Subsidiary Issuer, a suit by a Holder pursuant to Section 507 or a suit by Holders of more than 10% in outstanding principal amount of the Notes and Units. 82 Section 512 Trustee May Enforce Claims Without Possession of Notes or Units. All rights of action and claims under this Indenture, the Notes or the Units may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the Units 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, and any recovery of judgment shall, after provision for the payment of the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Units in respect of which such judgment has been recovered." SECTION 2.7. TRUSTEE Article Six of each of the Original Indentures is supplemented, amended and restated to read in its entirety as follows: "Article Six The Trustee Section 601 Duties of Trustee (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise 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 such Person's own affairs; provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security against loss, liability or expense satisfactory to the Trustee in its sole discretion. (b) Except during the continuance of an Event of Default: (i) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates, opinions or orders furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such certificates and opinions to determine whether or not they 83 conform on their face to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). (c) (1) 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: (A) this paragraph does not limit the effect of paragraph (b) of this Section 601; (B) 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; and (C) 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 505. (2) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section 601. (3) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Parent and the Subsidiary Issuer. (4) Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. (5) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. (6) Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 601 and to the provisions of the TIA. (7) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Parent or the Subsidiary Issuer shall be sufficient if signed by an 84 Officer of either the Parent or the Subsidiary Issuer, as the case may be. (8) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee reasonable security or indemnity satisfactory to it against the fees, costs, expenses (including reasonable attorneys' fees and expenses) and liabilities that might be incurred by it in compliance with such request or direction. Section 602 Rights of Trustee Subject to Section 601: (1) The Trustee may conclusively rely on any document (whether in its original or facsimile form) reasonably 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. (2) Before the Trustee acts or refrains from acting, it may require an Officers' Certificate and/or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on an Officers' Certificate or Opinion of Counsel. (3) 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. (4) 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, unless the Trustee's conduct constitutes willful misconduct or negligence. (5) The Trustee may consult with counsel of its selection, and the advice or opinion of counsel with respect to legal matters relating to this Indenture, the Notes and the Units shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel. (6) The Trustee is not required to make any inquiry or investigation into facts or matters stated in any document but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit and, if the Trustee determines to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Parent and the Subsidiary Issuer. 85 (7) The Trustee is not required to take notice or shall not be deemed to have notice of any Default or Event of Default hereunder, unless a Trust Officer of the Trustee has actual knowledge thereof or has received notice in writing of such Default or Event of Default from the Parent or the Subsidiary Issuer or the Holders of at least 25% in aggregate principal amount of the Notes comprising the Units then outstanding, and in the absence of any such notice, the Trustee may conclusively assume that no such Default or Event of Default exists. (8) The Trustee is not required to give any bond or surety with respect to the performance of its duties or the exercise of its powers under this Indenture. (9) In the event the Trustee receives inconsistent or conflicting requests and indemnity from two or more groups of Holders of Units, each representing less than the aggregate principal amount of Notes outstanding required to take any action thereunder, the Trustee, in its sole discretion may determine what action, if any, shall be taken. (10) The Trustee's immunities and protections from liability and its right to indemnification in connection with the performance of its duties under this Indenture shall extend to the Trustee's officers, directors, agents, attorneys and employees. Such immunities and protections and right to indemnification, together with the Trustee's right to compensation, shall survive the Trustee's resignation or removal, the discharge of this Indenture and final payments of the Units. (11) The permissive right of the Trustee to take actions permitted by this Indenture shall not be construed as an obligation or duty to do so. Section 603 Individual Rights of Trustee The Trustee in its individual or any other capacity may become the owner or pledgee of the Notes and Units and may otherwise deal with the Parent, the Subsidiary Issuer or its respective Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Sections 610 and Section 611. Section 604 Trustee's Disclaimer The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Notes or the Units, it shall not be accountable for the Parent's and the Subsidiary Issuer's use of the proceeds from the issuance of the Notes and Units, and it shall not be responsible for any statement of the Parent and the Subsidiary Issuer in this Indenture or in any document issued in connection with the sale of the Notes and Units or in the Notes or Units other than the Trustee's certificate of authentication. Section 605 Notice of Defaults 86 If a Default or Event of Default occurs and is continuing and if a Trust Officer has actual knowledge thereof, the Trustee shall mail to each Holder notice of the Default or Event of Default within 30 days after the Trustee has knowledge of such default. Except in the case of a Default or Event of Default in payment of principal of, premium (if any), or interest on any Note or Unit (including payments pursuant to the optional redemption or required repurchase provisions of such Note, if any), the Trustee may withhold the notice if and so long a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of Holders. Section 606 Reports by Trustee to Holders As promptly as practicable after each May 15, beginning with the May 15, following the date of this Indenture, and for so long as the Notes and Units remain outstanding, the Trustee shall mail to each Holder a brief report dated as of such reporting date that complies with TIA Section 313(a). The Trustee also shall comply with TIA Section 313(b). The Trustee shall also transmit by mail all reports required by TIA Section 313(c). A copy of each report at the time of its mailing to Holders shall be filed with the SEC and each stock exchange (if any) on which the Notes and the Units are listed. The Parent and the Subsidiary Issuer agree to notify promptly the Trustee whenever the Notes and the Units become listed on any stock exchange and of any delisting thereof. Section 607 Compensation and Indemnity Each of the Parent and the Subsidiary Issuer shall pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder as each of the Parent and the Subsidiary Issuer and the Trustee shall from time to time agree in writing. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Parent and the Subsidiary Issuer shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, costs of preparing and reviewing reports, certificates and other documents, costs of preparation and mailing of notices to Holders, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee's agents, counsel, accountants and experts. Each of the Parent and the Subsidiary Issuer shall indemnify the Trustee against any and all loss, liability, damages, claims or expense (including reasonable attorneys' fees and expenses) incurred by it without negligence or willful misconduct on its part in connection with the administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture (including this Section 607) and of defending itself against any claims (whether asserted by any Holder, the Parent, the Subsidiary Issuer or otherwise). The Trustee shall notify the Parent and the Subsidiary Issuer promptly of any claim for which it may seek 87 indemnity. Failure by the Trustee to so notify the Parent and the Subsidiary Issuer shall not relieve the Parent and the Subsidiary Issuer of their obligations hereunder. The Parent and the Subsidiary Issuer shall defend the claim and the Trustee shall provide reasonable cooperation at the Parent and the Subsidiary Issuer's expense in the defense. The Trustee may have separate counsel and the Parent and the Subsidiary Issuer shall pay the fees and expenses of such counsel provided that the Parent and the Subsidiary Issuer shall not be required to pay such fees and expenses if it assumes the Trustee's defense, and, in the reasonable judgment of outside counsel to the Trustee, there is no conflict of interest between the Parent and the Subsidiary Issuer and the Trustee in connection with such defense. The Parent and the Subsidiary Issuer shall not be under any obligation to pay for any written settlement without its consent, which consent shall not be unreasonably delayed, conditioned or withheld. The Parent and the Subsidiary Issuer need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee's own willful misconduct or negligence. To secure the Parent and the Subsidiary Issuer's payment obligations in this Section 607, the Trustee shall have a Lien prior to the Parent Notes or the Subsidiary Notes, as the case may be, on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on the Parent Notes or the Subsidiary Notes, as the case may be. The Parent and the Subsidiary Issuer's payment obligations pursuant to this Section 607 shall survive the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in clause (7) of Section 501 with respect to the Parent, the expenses are intended to constitute expenses of administration under any Bankruptcy Law. Section 608 Replacement of Trustee The Trustee may resign at any time by so notifying the Parent and the Subsidiary Issuer. The Holders of a majority in principal amount of the Notes comprising the then outstanding Units may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Parent and the Subsidiary Issuer shall remove the Trustee if: (1) the Trustee fails to comply with Section 610; (2) the Trustee is adjudged bankrupt or insolvent; (3) a receiver or other public officer takes charge of the Trustee or its property; or (4) the Trustee otherwise becomes incapable of acting. If the Trustee resigns or is removed by the Parent and the Subsidiary Issuer or by the Holders of a majority in principal amount of the then outstanding 88 Units and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of the Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Parent and the Subsidiary Issuer shall promptly appoint a successor Trustee. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Parent and the Subsidiary Issuer. Thereupon 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. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 607 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of at least 10% in principal amount of the then outstanding Units may petition, at the Parent and the Subsidiary Issuer's expense, any court of competent jurisdiction for the appointment of a successor Trustee. If the Trustee fails to comply with Section 610, unless the Trustee's duty to resign is stayed as provided in TIA Section 310(b), any Holder who has been a bona fide Holder of a Unit for at least six months may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. Notwithstanding the replacement of the Trustee pursuant to this Section 608, the obligations of the Parent and the Subsidiary Issuer under Section 607 shall continue for the benefit of the retiring Trustee. Section 609 Successor Trustee by Merger If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee. In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes and Units shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Notes and Units so authenticated; and in case at that time any of the Notes and Units shall not have been authenticated, any successor to the Trustee may authenticate such Notes and Units either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes and Units or in this Indenture. Section 610 Eligibility; Disqualification 89 The Trustee shall at all times satisfy the requirements of TIA Section 310(a). The Trustee shall have a combined capital and surplus of at least $100 million as set forth in its most recent published annual report of condition. The Trustee shall comply with TIA Section 310(b); provided, however, that there shall be excluded from the operation of TIA Section 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Parent or the Subsidiary Issuer are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(1) are met. Section 611 Preferential Collection of Claims Against the Parent or Subsidiary Issuer The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated." SECTION 2.8. DEFEASANCE AND COVENANT DEFEASANCE Article Fifteen of each of the Original Indentures is supplemented, amended and restated to read in its entirety as follows: "Article Fifteen DEFEASANCE AND COVENANT DEFEASANCE Section 1501 Discharge of Liability on Notes and Units; Defeasance (a) Subject to Section 1501(c), when (i)(x) the Parent or the Subsidiary Issuer delivers to the Trustee all outstanding Units (other than Units replaced pursuant to Section 1.6) for cancellation or (y) all outstanding Units not theretofore delivered for cancellation have become due and payable, whether at maturity or upon redemption or will become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name and at the expense of the Parent or the Subsidiary Issuer and the irrevocably deposits or causes to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders money in U.S. dollars, non-callable U.S. Government Securities, or a combination thereof, in such amounts as will be sufficient without consideration of any reinvestment of interest to pay and discharge the entire indebtedness on such Units not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption, (ii) no Default or Event of Default shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit and such deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Parent or the Subsidiary Issuer is a party or by which the Parent or the Subsidiary Issuer is bound; (iii) the Parent or the Subsidiary Issuer has paid or caused to be paid all sums payable by it under 90 this Indenture and the Units; and (iv) the Parent or the Subsidiary Issuer has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of such Units at maturity or the Redemption Date, as the case may be, then the Trustee shall acknowledge satisfaction and discharge of this Indenture on demand of the Parent or the Subsidiary Issuer (accompanied by an Officers' Certificate and an Opinion of Counsel stating that all conditions precedent specified herein relating to the satisfaction and discharge of this Indenture have been complied with) and at the cost and expense of the Parent or the Subsidiary Issuer, as the case may be. (b) Subject to Sections 1501(c) and 1502, the Parent or the Subsidiary Issuer at any time may terminate (i) all its obligations under the Units and this Indenture ("legal defeasance option"), and after giving effect to such legal defeasance, any omission to comply with such obligations shall no longer constitute a Default or Event of Default or (ii) its obligations under, Section 1004, Section 1005, Section 1006, Section 1007, Section 1008, Section 1009, Section 1010, Section 1011, Section 1012, Section 1013, Section 1014, Section 1015, Section 1017, clause (3) of Section 801 and Article Thirteen and the Parent or the Subsidiary Issuer may omit to 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 and such omission to comply with such covenants shall no longer constitute a Default or an Event of Default under Section 501(3) (solely as it relates to clause (3) of Section 801) and Section 501(4) and the operation of Sections 501(6), 501(7) (with respect only to Significant Subsidiaries) and 501(8) and the events specified in such Sections shall no longer constitute an Event of Default (clause (ii) being referred to as the "covenant defeasance option"), but except as specified above, the remainder of this Indenture and the Units shall be unaffected thereby. The Parent or the Subsidiary Issuer may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Parent or the Subsidiary Issuer exercises its covenant defeasance option, the Parent or the Subsidiary Issuer may elect to have any Subsidiary Guarantees in effect at such time terminate. If the Parent or the Subsidiary Issuer exercises its legal defeasance option, payment of the Units may not be accelerated because of an Event of Default, and the Parent Guarantees in effect at such time shall terminate. If the Parent exercises its covenant defeasance option, payment of the Units may not be accelerated because of an Event of Default specified in Section 501(3) (with respect only to the Parent's obligations under Article Thirteen), Section 501(4), Section 501(5), Section 501(6), Section 501(7) (with respect only to Significant Subsidiaries) or Section 501(8) or the failure of the Parent to comply with clause (3) of Section 801. 91 Upon satisfaction of the conditions set forth herein and upon request of the Parent or the Subsidiary Issuer, the Trustee shall acknowledge in writing the discharge of those obligations that the Parent or the Subsidiary Issuer terminates. (c) Notwithstanding the provisions of Section 1501(a) and Section 1501(b), the obligations of the Parent and the Subsidiary Issuer in Section 1.2, Section 1.3, Section 2.4, Section 2.5, Section 2.6, Section 2.7, Section 2.8, Section 2.9, Section 1001, Section 1002, Section 1003, Section 1016, Section 1018, Section 507, Section 607, Section 608, and in this Article Fifteen shall survive until the Notes and the Units have been paid in full. Thereafter, the obligations of the Parent and the Subsidiary Issuer in Section 607, Section 1504 and Section 1505 shall survive. Section 1502 Conditions to Defeasance The Parent or the Subsidiary Issuer may exercise its legal defeasance option or its covenant defeasance option only if: (a) the Parent or the Subsidiary Issuer irrevocably deposits in trust with the Trustee for the benefit of the Holders money in U.S. dollars or U.S. Government Securities or a combination thereof for the payment of principal, premium, if any, and interest on the Units to maturity or redemption, as the case may be; (b) the Parent or the Subsidiary Issuer delivers to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Securities plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal and interest when due on all the Units to maturity; (c) no Default or Event of Default shall have occurred and be continuing on the date of such deposit or, with respect to certain bankruptcy or insolvency Events of Default, on the 91st day after such date of deposit; (d) 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 Parent or the Subsidiary Issuer, as the case may be, or any of its subsidiaries is a party or by which the Parent or the Subsidiary Issuer, as the case may be or any of its subsidiaries is bound; (e) the Parent or the Subsidiary Issuer delivers to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940; 92 (f) in the case of the legal defeasance option, the Parent or the Subsidiary Issuer shall have delivered to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) in the United States stating that (i) the Parent or the Subsidiary Issuer has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the date of this Indenture there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such 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 had not occurred; (g) in the case of the covenant defeasance option, the Parent or the Subsidiary Issuer shall have delivered to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) in the United States to the effect that the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such deposit and covenant defeasance and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit and covenant defeasance had not occurred; and (h) the Parent or the Subsidiary Issuer delivers to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Notes and Units and this Indenture as contemplated by this Article Fifteen have been complied with. Section 1503 Application of Trust Money The Trustee shall hold in trust money or U.S. Government Securities deposited with it pursuant to this Article Fifteen. It shall apply the deposited money and the money from U.S. Government Securities through the Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Notes. Section 1504 Repayment to Parent or Subsidiary Issuer The Trustee and the Paying Agent shall promptly turn over to the Parent or the Subsidiary Issuer upon request any excess money or securities held by them upon payment of all the obligations under this Indenture. Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Parent or the Subsidiary Issuer upon request any money held by them for the payment of principal of or interest on the Units that remains unclaimed for two years, and, thereafter, Holders entitled to the money must look to the Parent or the Subsidiary Issuer for payment as general creditors. Section 1505 Indemnity for U.S. Government Securities 93 The Parent or the Subsidiary Issuer shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Securities or the principal and interest received on such U.S. Government Securities. Section 1506 Reinstatement If the Trustee or Paying Agent is unable to apply any money or U.S. Government Securities in accordance with this Article Fifteen by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Parent or the Subsidiary Issuer under this Indenture and the Units shall be revived and reinstated as though no deposit had occurred pursuant to this Article Fifteen until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Securities in accordance with this Article Fifteen; provided, however, that, if the Parent or the Subsidiary Issuer has made any payment of interest on or principal of any Notes because of the reinstatement of its obligations, the Parent or the Subsidiary Issuer shall be subrogated to the rights of the Holders of such Units to receive such payment from the money or U.S. Government Securities held by the Trustee or Paying Agent. The Trustee's rights under this Article Fifteen shall survive termination of this Indenture." SECTION 2.9. AMENDMENTS Article Nine of each of the Original Indentures is supplemented, amended and restated to read in its entirety as follows: "Article Nine AMENDMENTS Section 901 Supplemental Indentures Without Consent of Holders The Parent and the Subsidiary Issuer, each when authorized by a Board Resolution and the Trustee, at any time and from time to time, may amend or supplement this Indenture, the Notes or the Units, without the consent of any of the Holders of the Units, for any of the following purposes: (1) cure any ambiguity, omission, defect or inconsistency; (2) provide for the assumption by a successor corporation, partnership, trust or limited liability company of the obligations of the Parent or the Subsidiary Issuer under this Indenture; 94 (3) provide for uncertificated Units in addition to or in place of certificated Units (provided that the uncertificated Units are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Units are described in Section 163(f)(2)(B) of the Code); (4) add Guarantees with respect to the Notes; provided, however, that the designation is in accord with the applicable provisions of this Indenture; (5) secure the Notes; (6) add to the covenants of the Parent or the Subsidiary Issuer for the benefit of the Holders or surrender any right or power conferred upon the Parent or the Subsidiary Issuer; (7) make any change that does not adversely affect the rights of any Holder; (8) comply with any requirement of the SEC in connection with the qualification of this Indenture under the Trust Indenture Act; (9) provide for the issuance of exchange securities which shall have terms substantially identical in all respects to the Units (except that the transfer restrictions contained in the Units shall be modified or eliminated as appropriate) and which shall be treated, together with any outstanding Units, as a single class of securities; (9) make any change in the subordination provisions of this Indenture that would limit or terminate the benefits available to any holder of Senior Indebtedness of the Parent or the Subsidiary Issuer (or any Representative thereof) under such subordination provisions; (10) provide for the assumption by the Parent of the obligations of Subsidiary Issuer under the Subsidiary Notes and the related release of the Subsidiary of the Subsidiary Issuer from its obligations thereunder; or (11) provide for the release of the Parent Guarantee in accordance with this Indenture. Section 902 Supplemental Indentures With Consent of Holders The Parent and the Subsidiary Issuer, each when authorized by a Board Resolution and the Trustee, at any time and from time to time, may amend or supplement this Indenture, the Notes or the Units with the consent of the Holders of at least a majority in principal amount of the Notes (voting together as a single class) comprising Units then outstanding (including, without limitation, consents 95 obtained in connection with a purchase of, or tender offer or exchange offer for, Units) and, any past default or compliance with any provisions may be waived with the consent of the Holders of a majority in principal amount of the Notes (voting together as a single class) comprising Units then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Units). In addition, any amendment to Article Twelve that adversely affects the rights of any Holder of the Parent Notes or the Subsidiary Notes will require the consent of at least 66-2/3% in aggregate principal amount of the Parent Notes or Subsidiary Notes, respectively, then outstanding. However, without the consent of each Holder of an outstanding Unit affected, no amendment may, among other things: (1) reduce the principal amount of Notes comprising the Units whose Holders must consent to an amendment; (2) reduce the stated rate of or extend the stated time for payment of interest on any Note; (3) reduce the principal of or extend the Stated Maturity of any Note; (4) reduce the premium payable upon the redemption or repurchase of any Note or change the time at which any Note may be redeemed or repurchased as described above under Article Eleven, Section 1009 and Section 1017 or any similar provision, whether through an amendment or waiver of provisions in the covenants, definitions or otherwise; (5) make any Note payable in money other than that stated in the Note; (6) impair the right of any Holder to receive payment of, premium, if any, principal of and interest on such Holder's Notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder's Notes; (7) make any change in the amendment provisions which require each Holder's consent or in the waiver provisions; (8) make any change to the subordination provisions of this Indenture that adversely affects the rights of any Holder of Units. It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. After a supplemental indenture under this Section becomes effective, the Parent and the Subsidiary Issuer shall mail to Holders of Units a notice briefly describing such amendment. The failure to give such notice to all Holders of Units, or any defect therein, shall not impair the validity of a supplemental indenture under this section. 96 Section 903 Execution of Supplemental Indentures In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Officer's Certificate and Opinion of Counsel from the Parent and the Subsidiary Issuer stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee's own rights, duties or immunities under this Indenture or otherwise. Section 904 Effect of Supplemental Indentures Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Units theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. Section 905 Conformity with Trust Indenture Act Every amendment or supplement to this Indenture, the Notes or the Units executed pursuant to this Article shall comply with the requirements of the TIA as then in effect. Section 906 Reference in Notes and Units to Supplemental Indentures Notes and Units authenticated and delivered after the execution of any supplemental indenture pursuant to this Article Nine may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Parent or the Subsidiary Issuer shall so determine, new Notes and any Parent Guarantees endorsed thereon and new Units so modified as to conform, in the opinion of the Trustee, the Parent and the Subsidiary Issuer, to any such supplemental indenture may be prepared and executed by the Parent and the Subsidiary Issuer and such new Notes and Units may be authenticated and delivered by the Trustee in exchange for outstanding Notes and Units." SECTION 2.10. SUBORDINATION OF NOTES Article Twelve of each of the Original Indentures is hereby supplemented, amended and restated to read in its entirety as follows: "Article Twelve SUBORDINATION OF NOTES 97 Section 1201 Notes Subordinate to Senior Indebtedness The Parent covenants and agrees, and each Holder of a Parent Note, by accepting a Parent Note, likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this Article, the payment of the principal of (and premium, if any) and interest on each and all of the Parent Notes is hereby expressly made subordinate in right of payment to the prior payment in full of all existing and future Senior Indebtedness of the Parent. The Subsidiary Issuer covenants and agrees, and each Holder of a Subsidiary Note, by accepting a Subsidiary Note, likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this Article, the payment of the principal of (and premium, if any) and interest on each and all of the Subsidiary Notes (and any Additional Amounts) is hereby expressly made subordinate in right of payment to the prior payment in full of all existing and future Senior Indebtedness of the Subsidiary Issuer. Section 1202 Liquidation, Dissolution and Bankruptcy of Parent and Subsidiary Issuer (a) Upon any distribution to creditors of the Parent in a liquidation or dissolution of the Parent or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Parent or its property, an assignment for the benefit of creditors or any marshalling of the Parent's assets and liabilities: (1) holders of Senior Indebtedness of the Parent shall be entitled to receive payment in full in cash (or U.S. dollar-denominated Cash Equivalents) of such Senior Indebtedness (including interest after the commencement of any such proceeding at the rate specified in the applicable Senior Indebtedness) before the Holders of the Parent Notes shall be entitled to receive any payment of any kind or character with respect to the Parent Notes; and (2) until the Senior Indebtedness of the Parent is paid in full in cash (or U.S. dollar-denominated Cash Equivalents), any distribution to which the Holders of Parent Notes would be entitled but for this Article shall be made to the holders of the Senior Indebtedness of the Parent. Notwithstanding the foregoing, Holders of Parent Notes may receive (i) securities that are subordinated at least to the same extent as the Parent Notes to Senior Indebtedness and any securities issued in exchange for Senior Indebtedness and (ii) payments made from the defeasance trusts described in Article Fifteen. 98 (b) Upon any distribution to creditors of the Subsidiary Issuer in a liquidation or dissolution of the Subsidiary Issuer or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Subsidiary Issuer or its property, an assignment for the benefit of creditors or any marshalling of the Subsidiary Issuer's assets and liabilities: (1) holders of Senior Indebtedness of the Subsidiary Issuer shall be entitled to receive payment in full in cash (or U.S. dollar-denominated Cash Equivalents) of such Senior Indebtedness (including interest after the commencement of any such proceeding at the rate specified in the applicable Senior Indebtedness) before the Holders of Subsidiary Notes shall be entitled to receive any payment of any kind or character with respect to the Subsidiary Notes; and (2) until the Senior Indebtedness of the Subsidiary Issuer is paid in full in cash (or U.S. dollar-denominated Cash Equivalents), any distribution to which the Holders of Subsidiary Notes would be entitled but for this Article shall be made to the holders of the Senior Indebtedness of the Subsidiary Issuer. Notwithstanding the foregoing, Holders of Subsidiary Notes may receive (i) securities that are subordinated at least to the same extent as the Subsidiary Notes to Senior Indebtedness of the Subsidiary Issuer and any securities issued in exchange for Senior Indebtedness of the Subsidiary Issuer and (ii) payments made from the trusts described in Article Fifteen. Section 1203 Suspension of Payment When Senior Indebtedness in Default (a) The Parent and the Subsidiary Issuer may not pay principal of, premium if any, or interest on, or other payment obligations in respect of, the Notes or make any deposit pursuant to the provisions described under Article Fifteen and may not otherwise purchase, redeem or retire any Notes or Units (collectively, "pay the Notes") if: (1) any Senior Indebtedness is not paid when due in cash or Cash Equivalents or (2) any other default or Senior Indebtedness occurs and the maturity of such Senior Indebtedness is accelerated in accordance with its terms unless, in either case, the default has been cured or waived and any such acceleration has been rescinded or such Senior Indebtedness has been paid in full in cash or Cash Equivalents. However, the Parent and the Subsidiary Issuer may pay the Notes if the Parent and the Trustee receive written notice approving such payment from the Representative of the Senior Indebtedness with respect to which either of the events set forth in clause (1) or (2) of the immediately preceding sentence has occurred and is continuing. 99 (b) The Parent and the Subsidiary Issuer also will not be permitted to pay the Notes for a Payment Blockage Period (as defined below) during the continuance of any default (a "Non-Payment Default"), other than a Payment Default described in Section 1203(a) hereof, on any Designated Senior Indebtedness that permits the holders of the Designated Senior Indebtedness to accelerate its maturity immediately without either further notice (except such notice as may be required to effect such acceleration) or the expiration of any application grace periods. A "Payment Blockage Period" commences on the receipt by the Trustee (with a copy to the Parent) of written notice (a "Blockage Notice") of a default of the kind described in the immediately preceding sentence from the Representative of the holders of such Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period and ends on the earliest of (a) 179 days thereafter, (b) the date on which such Non-Payment Default is cured, waived in writing or ceases to exist, (c) the date on which such Designated Senior Indebtedness is repaid in full or (d) the date on which such Payment Blockage Period will have been terminated by written notice to the Trustee and the Parent from the Person or Persons who gave such Blockage Notice. The Parent and the Subsidiary Issuer may resume payments on the Notes after the end of the Payment Blockage Period (including any missed payments), unless the holders of such Designated Senior Indebtedness or the Representative of such holders have accelerated the maturity of such Designated Senior Indebtedness. Not more than one Blockage Notice may be given in any consecutive 360-day period, irrespective of the number of defaults with respect to Designated Senior Indebtedness during such period. In no event, however, may the total number of days during which any Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during any 360 consecutive day period. For purposes of this paragraph, no default or event of default that existed or was continuing on the date of the commencement of any Payment Blockage Period with respect to the Designated Senior Indebtedness initiating such Payment Blockage Period shall be, or be made, the basis of the commencement of a subsequent Payment Blockage Period by the Representative of such Designated Senior Indebtedness, whether or not within a period of 360 consecutive days, unless such default or event of default shall have been cured or waived for a period of not less than 90 consecutive days. (c) If payment of the Notes is accelerated because of an Event of Default, the Parent or the Trustee will promptly notify the holders of the Designated Senior Indebtedness or the Representatives of such holders of the acceleration. The Parent and the Subsidiary Issuer may not pay the Notes until five Business Days after such acceleration and, after that five Business Day period, may pay the Notes only if the subordination provisions of this Indenture otherwise permit payment at that time. (d) In the event that, notwithstanding the foregoing, the Parent or the Subsidiary Issuer will make any payment to the Trustee or the Holder of any Note 100 prohibited by the foregoing provisions of this Section, then and in such event such payment will be paid over and delivered forthwith to the Parent or the Subsidiary Issuer, as the case may be. In the event that the Parent or the Subsidiary Issuer will make any payment in respect of the Notes to the Trustee and the Trustee will receive written notice of a Payment Default or a Non-payment Default from one or more of the holders of Designated Senior Indebtedness (or their representative) prior to making any payment to Holders in respect of the Notes and prior to 11:00 a.m. Eastern Time, on the date which is two Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose, such payments will be paid over by the Trustee and delivered forthwith to the Parent or the Subsidiary Issuer, as the case may be. Section 1204 Subrogation to Rights of Holders of Senior Indebtedness (a) After all Senior Indebtedness of the Parent is irrevocably paid in full in cash or U.S. dollar-denominated Cash Equivalents reasonably satisfactory to the holders thereof and until the Parent Notes are paid in full, Holders of Parent Notes shall be subrogated (equally and ratably with all other Indebtedness pari passu with the Parent Notes) to the rights of holders of Senior Indebtedness of the Parent to receive distributions applicable to such Senior Indebtedness. A distribution made under this Article to holders of Senior Indebtedness of the Parent that otherwise would have been made to Holders of the Parent Notes is not, as between the Parent and the Holders of Parent Notes, a payment by the Parent on the Senior Indebtedness of the Parent. (b) After all Senior Indebtedness of the Subsidiary Issuer is irrevocably paid in full in cash or U.S. dollar-denominated Cash Equivalents reasonably satisfactory to the holders thereof and until the Subsidiary Notes are paid in full, Holders of Subsidiary Notes shall be subrogated (equally and ratably with all other Indebtedness pari passu with the Subsidiary Notes) to the rights of holders of Senior Indebtedness of the Subsidiary Issuer to receive distributions applicable to such Senior Indebtedness. A distribution made under this Article to holders of Senior Indebtedness of the Subsidiary Issuer that otherwise would have been made to Holders of the Subsidiary Notes is not, as between the Parent and the Holders of Subsidiary Notes, a payment by the Subsidiary Issuer on the Senior Indebtedness of the Subsidiary Issuer. Section 1205 Provisions Solely to Define Relative Rights This Article defines the relative rights of Holders of Notes and Units and holders of Senior Indebtedness. Nothing in this Indenture shall: (1) impair, as between the Parent and Holders of Parent Notes and between the Subsidiary Issuer and Holders of Subsidiary Notes, the obligation of the Parent and the Subsidiary Issuer, which is absolute and unconditional, to pay principal of and interest on the 101 Parent Notes and the Subsidiary Notes, as the case may be, in accordance with their respective terms; (2) affect the relative rights of Holders of Notes and Units and other creditors of the Parent or the Subsidiary Issuer, as the case may be, other than their rights in relation to holders of Senior Indebtedness; or (3) prevent the Trustee or any Holder of Notes or Units from exercising its available remedies upon a Default or Event of Default, subject to the rights of holders and owners of Senior Indebtedness to receive distributions and payments otherwise payable to Holders of Parent Notes or Subsidiary Notes. If the Parent of the Subsidiary Issuer fails because of this Article to pay principal of or interest on a Notes on the due date, the failure is still a Default or Event of Default. Section 1206 Trustee to Effectuate Subordination Each Holder of a Parent Note and a Subsidiary Issuer Note by his acceptance thereof authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article and appoints the Trustee his attorney-in-fact for any and all such purposes. Section 1207 No Waiver of Subordination Provisions (a) No right of any present or future holder of any Senior Indebtedness of the Parent or the Subsidiary Issuer to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Parent or the Subsidiary Issuer, as the case may be, or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Parent or the Subsidiary Issuer with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. (b) Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness of the Parent or the Subsidiary Issuer may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders of the Parent Notes or the Subsidiary Notes, without incurring responsibility to the Holders of the Parent Notes or the Subsidiary Notes and without impairing or releasing the subordination provided in this Article or the obligations hereunder of the Holders of the Parent Notes or the Subsidiary Notes to the holders of Senior Indebtedness of the Parent or the Subsidiary Issuer, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Indebtedness of the Parent or the Subsidiary Issuer, or otherwise amend or supplement in any 102 manner Senior Indebtedness of the Parent or the Subsidiary Issuer or any instrument evidencing the same or any agreement under which Senior Indebtedness of the Parent or the Subsidiary Issuer is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness of the Parent or the Subsidiary Issuer; (iii) release any Person liable in any manner for the collection of Senior Indebtedness of the Parent or the Subsidiary Issuer; and (iv) exercise or refrain from exercising any rights against the Parent or the Subsidiary Issuer and any other Person. Section 1208 Notice to Trustee (a) The Parent and the Subsidiary Issuer shall give prompt written notice to the Trustee of any fact known to the Parent or the Subsidiary Issuer which would prohibit the making of any payment to or by the Trustee in respect of the Parent Notes or the Subsidiary Notes. Notwithstanding the provisions of this Article or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment to or by the Trustee in respect of the Parent Notes or the Subsidiary Notes, unless and until the Trustee shall have received written notice thereof from the Parent or the Subsidiary Issuer or a holder of Senior Indebtedness of the Parent or the Subsidiary Issuer (or from any Representative therefor) with respect to a Payment Default, or one or more of the holders of Designated Senior Indebtedness (or from any Representative therefor), with respect to a Non-Payment Default; and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of TIA Sections315(a) through 315(d), shall be entitled in all respects to assume that no such facts exist; provided, however, that if the Trustee shall not have received the notice provided for in this Section at least three Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose (including, without limitation, the payment of the principal of (and premium, if any) or interest on any Parent Notes or Subsidiary Notes), then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purpose for which such money was received and shall not be affected by any notice to the contrary which may be received by it within three Business Days prior to such date. (b) Subject to TIA Sections315(a) through 315(d), the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Indebtedness of the Parent or the Subsidiary Issuer (or a trustee therefor) to establish that such notice has been given by a holder of Senior Indebtedness of the Parent or the Subsidiary Issuer (or a trustee therefor). In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness of the Parent or the Subsidiary Issuer to participate in any payment or distribution pursuant to this Article, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness of the Parent or the Subsidiary Issuer held by such Person, 103 the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article. Section 1209 Reliance on Judicial Order or Certificate of Liquidating Agent Upon any payment or distribution of assets of the Parent or the Subsidiary Issuer referred to in this Article, the Trustee, subject to TIA Sections 315(a) through 315(d), and the Holders of the Parent and the Subsidiary Notes shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Indebtedness of the Parent and the Subsidiary Issuer, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article. Section 1210 Trustee Not Fiduciary for Holders of Senior Indebtedness The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness of the Parent or the Subsidiary Issuer and shall not be liable to any such holders if the Trustee shall in good faith mistakenly pay over or distribute to Holders of Parent Notes or Subsidiary Notes, as the case may be, or to the Parent or the Subsidiary Issuer or to any other Person cash, property or securities to which any holders of Senior Indebtedness of the Parent or the Subsidiary Issuer shall be entitled by virtue of this Article or otherwise. Section 1211 Rights of Trustee as Holder of Senior Indebtedness; Preservation of Trustee's Rights The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article with respect to any Senior Indebtedness of the Parent or the Subsidiary Issuer which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness of the Parent or the Subsidiary Issuer, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. Nothing in this Article shall apply to claims of, or payments to, the Trustee under or pursuant to Section 607." 104 SECTION 2.11. PARENT GUARANTEE Each of the Original Indentures is hereby supplemented and amended by the addition of a new Article Thirteen which shall read in its entirety as follows: "Article Thirteen PARENT GUARANTEE Section 1301 Parent Guarantee The Parent hereby unconditionally guarantees to each Holder of a Subsidiary Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes, the Units or the obligations of the Subsidiary Issuer or the Parent hereunder or thereunder, that: (a) the principal of, premium, if any, and interest on the Subsidiary Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium, and interest on the Subsidiary Notes, if any, if lawful, and all other obligations of the Subsidiary Issuer to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Subsidiary Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Parent shall be obligated to pay the same immediately. The Parent agrees that this Parent Guarantee is a general unsecured senior subordinated obligation of the Parent and it is a guarantee of payment and not a guarantee of collection. The Parent hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes, the Units or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Subsidiary Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Subsidiary Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. The Parent hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Subsidiary Issuer, any right to require a proceeding first against the Subsidiary Issuer, protest, notice and all demands whatsoever and covenants that this Parent Guarantee shall not be discharged except by complete performance of the obligations contained in the Subsidiary Notes, the Units and this Indenture. If any Holder or the Trustee is required by any court or otherwise to return to the Subsidiary Issuer, the Parent, or any custodian, trustee, liquidator or other 105 similar official acting in relation to either the Subsidiary Issuer or the Parent any amount paid by the Subsidiary Issuer or the Parent either to the Trustee or such Holder, this Parent Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

The Guarantor agrees to be bound by all of the provisions of the Indenture applicable to a Subsidiary Guarantor and to perform all of the obligations and agreements of a Subsidiary Guarantor under the Indenture. SECTION 2.2. Subsidiary Guarantee. (a) Subsidiary Guarantee. Each Subsidiary Guarantor hereby fully, unconditionally and irrevocably guarantees, as primary obligor and not merely as surety, jointly and severally with each other Subsidiary Guarantor, to each Holder of the Securities and the Trustee the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the principal of and interest, including Additional Amounts, if any, on the Securities and all other obligations and liabilities of the Parent and the Subsidiary Issuer under the Indenture (including, without limitation, interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, relating to the Parent, the Subsidiary Issuer or any Subsidiary Guarantor whether or not a claim for post-filing or post-petition interest is allowed in such proceeding) (all the foregoing being hereinafter collectively called the "Obligations"). Each Subsidiary Guarantor further agrees (to the extent permitted by law) that the Obligations may be extended or renewed, in whole or in part, without notice or further assent from it, and that it will remain bound under this Section 2.2 hereto notwithstanding any extension or renewal of any Obligation. Each Subsidiary Guarantor waives presentation to, demand of payment from and protest to the Parent or the Subsidiary Issuer of any of the Obligations and also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any default under the Securities or the Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (a) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Parent or the Subsidiary Issuer or any other person under the Indenture, the Securities or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of the Indenture, the Securities or any other agreement; (d) the release of any security held by any c-2 Holder or the Trustee for the Obligations or any of them; (e) the failure of any Holder to exercise any right or remedy against any other Subsidiary Guarantor; or (f) any change in the ownership of the Parent or the Subsidiary Issuer. Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee herein constitutes a Guarantee of payment when due (and not a Guarantee of collection) and waives any right to require that any resort be had by any Holder to any security held for payment of the Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder to assert any claim or demand or to enforce any remedy under the Indenture, the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity. Subject to the provisions of Section 1013, each Subsidiary Guarantor agrees that its Subsidiary Guarantee herein shall remain in full force and effect until payment in full of all the Obligations or such Subsidiary Guarantor is released from its Subsidiary Guarantee upon the merger or the sale of all the Capital Stock or assets of the Subsidiary Guarantor in compliance with Section 2.2(b) hereto. Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest and Additional Amounts, if any, on any of the Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of the Company or otherwise. In furtherance of the foregoing and not in limitation of any other right which any Holder has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay any of the Obligations when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, each Subsidiary Guarantor hereby promises to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders an amount equal to the sum of (i) the unpaid amount of such Obligations then due and owing and (ii) accrued and unpaid interest and Additional Amounts, if any, on such Obligations then due and owing (but only to the extent not prohibited by law). Each Subsidiary Guarantor further agrees that, as between such Subsidiary Guarantor, on the one hand, and the Holders, on the other hand, (x) the maturity of the Obligations guaranteed hereby may be accelerated as provided in the Indenture for the purposes of its Subsidiary Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby and (y) in the event c-3 of any such declaration of acceleration of such Obligations, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantor for the purposes of this Subsidiary Guarantee. Each Subsidiary Guarantor also agrees to pay any and all reasonable costs and expenses (including reasonable attorneys' fees) incurred by the Trustee or the Holders in enforcing any rights under this Section.

(1) The obligations of each Subsidiary Guarantor hereunder will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to its contribution obligations under the Indenture, result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law and not otherwise being void or voidable under any similar laws affecting the rights of creditors generally. (2) Each Subsidiary Guarantor may consolidate with or merge into or sell its assets to the Company or another Subsidiary Guarantor without limitation.

Upon the sale or disposition of a Subsidiary Guarantor (by merger, consolidation, the sale of its Capital Stock or the sale of all or substantially all of its assets (other than by lease)) and whether or not the Subsidiary Guarantor is the surviving corporation in such transaction to a Person (whether or not an Affiliate of the Subsidiary Guarantor) which is not the Parent or a Subsidiary of the Parent, which sale or disposition is otherwise in compliance with the Indenture, such Subsidiary Guarantor will be released from all its obligations under the Indenture and its Subsidiary Guarantee and such Subsidiary Guarantee will terminate. (3) Each Subsidiary Guarantor will be deemed released from all its obligations under the Indenture and its Subsidiary Guarantee and such Subsidiary Guarantee will terminate upon the discharge of the Securities pursuant to the provisions of Article IV of the Indenture. (c) Right of Contribution. Each Subsidiary Guarantor hereby agrees that to the extent that any Subsidiary Guarantor shall have paid more than its proportionate share of any payment made on the obligations under the Subsidiary Guarantees, such Subsidiary Guarantor c-4 shall be entitled to seek and receive contribution from and against the Parent or the Subsidiary Issuer or any other Subsidiary Guarantor who has not paid its proportionate share of such payment. The provisions of this Section 2.2(c) shall in no respect limit the obligations and liabilities of each Subsidiary Guarantor to the Trustee and the Holders and each Subsidiary Guarantor shall remain liable to the Trustee and the Holders for the full amount guaranteed by such Subsidiary Guarantor hereunder. (d) No Subrogation. Notwithstanding any payment or payments made by each Subsidiary Guarantor hereunder, no Subsidiary Guarantor shall be entitled to be subrogated to any of the rights of the Trustee or any Holder against the Parent or the Subsidiary Issuer or any other Subsidiary Guarantor or any collateral security or guarantee or right of offset held by the Trustee or any Holder for the payment of the Obligations, nor shall any Subsidiary Guarantor seek or be entitled to seek any contribution or reimbursement from the Company or any other Subsidiary Guarantor in respect of payments made by such Subsidiary Guarantor hereunder, until all amounts owing to the Trustee and the Holders by the Company on account of the Obligations are paid in full. If any amount shall be paid to any Subsidiary Guarantor on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held by such Subsidiary Guarantor in trust for the Trustee and the Holders, segregated from other funds of such Subsidiary Guarantor, and shall, forthwith upon receipt by such Subsidiary Guarantor, be turned over to the Trustee in the exact form received by such Subsidiary Guarantor (duly indorsed by such Subsidiary Guarantor to the Trustee, if required), to be applied against the Obligations.
